Protection of publicly distributed software components

The nature of client-server architecture implies that some modules are delivered to customers. These publicly distributed commercial software components are under risk, because users (and simultaneously potential malefactors) have physical access to some components of the distributed system. The problem becomes even worse if interpreted programming languages are used for creation of client side modules. The language Java, which was designed to be compiled into platform independent byte-code is not an exception and runs the additional risk. Along with advantages like verifying the code before execution (to ensure that program does not produce some illegal operations)Java has some disadvantages. On a stage of byte-code a java program still contains comments, line numbers and some other instructions, which can be used for reverse-engineering. This Master's thesis focuses on protection of Java code based client-server applications. I present a mixture of methods to protect software from tortious acts. Then I shall realize all the theoretical assumptions in a practice and examine their efficiency in examples of Java code. One of the criteria's to evaluate the system is that my product is used for specialized area of interactive television.

Water vapor tightness of packages: methods and optimizing

Työn tarkoituksena oli testata jo tutkimuskeskuksella käytössä ollutta ja tutkimuskeskukselle tässä työssä kehitettyä pakkauksen vesihöyrytiiveyteen liittyvää mittausmenetelmää. Saatuja tuloksia verrattiin keskenään sekä materiaalista mitattuihin arvoihin. Elintarvikepakkauksia tutkittiin myös kosteussensoreiden, säilyvyyskokeen sekä kuljetussimuloinnin avulla. Optimoinnilla tutkittiin pakkauksen muodon vaikutusta vesihöyrytiiveyteen. Pakkauksen vesihöyrynläpäisyn mittaamiseen kehitetty menetelmä toimi hyvin ja sen toistettavuus oli hyvä. Verrattaessa sitä jo olemassa olleeseen menetelmään tulokseksi saatiin, että uusi menetelmä oli nopeampi ja vaati vähemmän työaikaa, mutta molemmat menetelmät antoivat hyviä arvoja rinnakkaisille näytteille. Kosteussensoreilla voitiin tutkia tyhjän pakkauksen sisällä olevan kosteuden muutoksia säilytyksen aikana. Säilyvyystesti tehtiin muroilla ja parhaan vesihöyrysuojan antoivat pakkaukset joissa oli alumiinilaminaatti- tai metalloitu OPP kerros. Kuljetustestauksen ensimmäisessä testissä pakkauksiin pakattiin muroja ja toisessa testissä nuudeleita. Kuljetussimuloinnilla ei ollutvaikutusta pakkausten sisäpintojen eheyteen eikä siten pakkausten vesihöyrytiiveyteen. Optimoinnilla vertailtiin eri muotoisten pakkausten tilavuus/pinta-ala suhdetta ja vesihöyrytiiveyden riippuvuutta pinta-alasta. Optimaalisimmaksi pakkaukseksi saatiin pallo, jonka pinta-ala oli pienin ja materiaalin sallima vesihöyrynläpäisy suurin ja vesihöyrybarrierin määrä pienin.

EU:n uuden kemikaaliasetuksen ja REACH järjestelmän vaikutukset ABB Oy, Sähkökoneisiin

EU on valmistelemassa uutta kemikaaliasetusta joka sisältää myös nk. REACH järjestelmän. Uusi asetus tulee voimaan vuonna2006 tai 2007. Uudella asetuksella pyritään mm. parantamaan ihmisten terveyden ja luonnon suojelua, sekä selventämään nykyään hyvin sekavaa EU:n kemikaalilainsäädäntöä. Kemikaaliasetus koskee kemikaalien valmistusta, maahantuontia ja käyttöä valmistusprosesseissa. Tässä diplomityössä tarkastellaan uuden kemikaaliasetuksen ja REACH järjestelmän aiheuttamia vaikutuksia sähkömoottoreiden ja -generaattoreiden valmistukseen ABB Oy, Sähkökoneiden kannalta. Työssä on tarkasteltu uuden kemikaaliasetuksen tuomia muutoksia kemikaaliturvallisuuden hallintaan ja kemikaalikustannuksiin. Työssä tarkastellaan ABB Oy, Sähkökoneiden roolia jatkokäyttäjänä. Työssä on tarkastellut myös mitä vaikutuksia aineiden mahdollisilla poistumisilla markkinoilta olisi tuotantoprosessiin. Vaikutukset näkyvät pääasiassakemikaalikustannusten nousuna ja muutoksina kemikaali turvallisuuden hallinnassa, lisäksi markkinoilta saattaa poistua valmistuksen kannalta tärkeitä kemikaaleja. Asetuksen voimaantulon aiheuttamien lopullisten kustannusten määrään vaikuttaa suuresti se kuinka paljon aineita poistuu markkinoilta ja kuinka paljon tämän takia joudutaan tekemään muutoksia valmistusprosessissa.

Partial protection and intrathecal invasion of CD8(+) T cells in acute canine distemper virus infection.

Initial non-inflammatory demyelination in canine distemper virus infection (CDV) develops against a background of severe immunosuppression and is therefore, thought to be virus-induced. However, recently we found a marked invasion of T cells throughout the central nervous system (CNS) in dogs with acute distemper despite drastic damage to the immune system. In the present study, this apparent paradox was further investigated by immunophenotyping of lymphocytes, following experimental CDV challenge in vaccinated and non-vaccinated dogs. In contrast to CDV infected, unprotected dogs, vaccinated dogs did not become immunosuppressed and exhibited a strong antiviral immune response following challenge with virulent CDV. In unprotected dogs rapid and drastic lymphopenia was initially due to depletion of T cells. In peripheral blood, CD4(+) T cells were more sensitive and depleted earlier and for a longer time than CD8(+) cells which recovered soon. In the cerebrospinal fluid (CSF) we could observe an increase in the T cell to B cell and CD8(+) to CD4(+) ratios. Thus, partial protection of the CD8(+) cell population could explain why part of the immune function in acute distemper is preserved. As found earlier, T cells invaded the CNS parenchyma in these dogs but also in the protected challenged dogs, which did not develop any CNS disease at all. Since markers of T cell activation were upregulated in both groups of animals, this phenomenon could in part be related to non-specific penetration of activated T cells through the blood brain barrier. However, in diseased animals much larger numbers of T cells were found in the CNS than in the protected dogs, suggesting that massive invasion of T cells in the brain requires CDV expression in the CNS.

Polttodirektiivien soveltaminen sellutehtaiden ilmapäästömittauksissa

EU:n polttodirektiivit, LCP- ja jätteenpolttodirektiivi ovat arkipäivää suuressa osassa polttolaitoksia Suomessakin lähivuosien kuluessa. Molemmat direktiivit on otettu mukaan Suomen lain-säädäntöön asetuksina, joita on hieman muutettu vastaamaan kansallisia tarpeita. Polttolaitokset tulevat muuttamaan aikaisempia käytäntöjään päästöistä mitattavien komponenttien sekä tarkkailujaksojen että raportoinnin osalta. Mittausten tulokset raportoidaan jatkossa yksikössä mg/Nm3. Jatkuvatoimisia mittausjärjestelmiä on asennettava yhä useampaan laitokseen ja savukaasuista tarkkaillaan pitoisuuksia päästöjen sijaan. Edelleen raportoidaan esim. ympäristölupaviranomaiselle vuosipäästöjen suuruus. Vuonna 2000 voimaan tulleen ympäristönsuojelulain ja -asetuksen velvoittamina toiminnassa olevat sellutehtaat ovat hakeneet uuden lain mukaista ympäristölupaa vuoden 2004 loppuun mennessä. Ympäristöluvan tarvitsevat myös kaikki teholtaan yli 50 MW:n polttolaitokset. Suuria polttolaitoksia koskeva LCP-direktiivi astuu voimaan vuoden 2008 alussa. Siksi uusissa ympäristöluvissa tullaantodennäköisesti vaatimaan myös sellutehtailta ko. direktiivin mukaisia mittaus-järjestelmiä ja päästörajoja. Laitoksissa on jo nyt melko kattavat päästömittausjärjestelmät, sillä myös voimassaolevat ympäristöluvat ja ilmapäästöjen tarkkailuohjelmat velvoittavat päästöjen jatkuvaan seurantaan pääosin samoista savukaasukomponenteista kuin mitä direktiivissäkin edellytetään. Tässä diplomityössä keskitytään LCP- ja jätteenpolttodirektiivien mittausvaatimuksiin, raja-arvoihin sekä raportointiin sekä Metsä-Botnian sellutehtaiden mittausjärjestelmien parantamis-toimenpiteisiin. Yksityiskohtainen toimintamalli on tehty Joutsenon tehtaan laitosta ja mittaus-järjestelmää silmällä pitäen. Sitä voidaan käyttää myös muillatehtailla mallina savukaasupäästöjen mittauksien ja laitteiden päivitysten yhteydessä. Toimintamalliin siirtyminen ei velvoita Metsä-Botnian tehtaita, mutta monet tehtaat haluavat laitteistokannan uusimisen yhteydessä siirtyä direktiivien vaatimuksia vastaavaan järjestelmään.

Does the working environment influence health care professionals' values, meaning in life and religiousness? Palliative care units compared with maternity wards.

CONTEXT: Increased altruism, self-transcendence, and quests for meaning in life (MiL) have been found in palliative care (PC) patients and their families who experience the finiteness of life. Similar changes were observed in healthy subjects who were experimentally confronted with their mortality. OBJECTIVES: The study investigated how daily experiences of the transitoriness of life influence PC health care professionals' (HCPs) values, MiL, and religiousness. METHODS: In a cross-sectional study, the Schwartz Value Survey, the Schedule for Meaning in Life Evaluation, and the Idler Index of Religiosity were used to investigate personal values, MiL, and private religiousness. HCPs working in PC (confronted with death) were compared with a control group of HCPs working at maternity wards (MWs) using multivariate models. Differences were considered to be statistically significant at P < 0.05. RESULTS: Seventy PC- and 70 MW-HCPs took part in the study (response rate 74.0%). No differences between the groups were found in overall MiL satisfaction scores. PC-HCPs were significantly more religious than MW-HCPs; they listed spirituality and nature experience more often as areas in which they experience MiL. Furthermore, hedonism was more important for PC-HCPs, and they had higher scores in openness-to-change values (stimulation and self-direction). MW-HCPs were more likely to list family as a MiL area. They assigned more importance to health and scored higher in conservation values (conformity and security). Duration of professional experience did not influence these results. CONCLUSION: Basic differences in values, MiL, and religiousness between PC-HCPs and MW-HCPs might have influenced the choice of working environment because no effect of job duration was observed. Longitudinal research is needed to confirm this hypothesis.

Clinical chemistry variables in normal elderly and healthy ambulatory populations: comparison with reference values.

Laboratory values of the most commonly assayed clinical chemistry variables were determined in selected elderly and healthy ambulatory populations. The upper and lower limits (2.5 and 97.5 fractiles) were compared with the adult reference values in use in university hospitals of Switzerland. The results suggest that conventional adult reference values can be used for most variables in the elderly and that these values are also useful in an ambulatory population.

Balancing knowledge sharing and protection in collaborative innovation - The roles and dynamics of contracts, IPR's and trust

Pro-gradu tutkielman tavoitteena on tutkia, miten yritykset tasapainoilevat tiedon jakamisen ja suojaamisen välillä innovaatioyhteistyöprojekteissa, ja miten sopimukset, immateriaalioikeudet ja luottamus voivat vaikuttaa tähän tasapainoon. Yhteistyössä yritysten täytyy jakaa tarpeellista tietoa kumppanilleen, mutta toisaalta niiden täytyy varoa, etteivät ne menetä ydinosaamiseensa kuuluvaa tietoa ja kilpailuetuaan. Yrityksillä on useita keinoja tietovuodon estämiseen. Tutkielmassa keskitytään patenttien, sopimusten ja liikesalaisuuksien käyttöön tietoa suojaavina mekanismeina. Kyseiset suojamekanismit vaikuttavat luottamukseen kumppaneiden välillä, ja täten myös näiden halukkuuteen jakaa tietoa kumppaneilleen. Jos kumppanit eivät jaa tarpeeksi tietoa toisilleen, voi yhteistyö epäonnistua. Sopimusten, immateriaalioikeuksien ja luottamuksen rooleja ja vuorovaikutusta tutkitaan kahdenvälisissä yhteistyöprojekteissa. Tutkielmassa esitellään neljä case-esimerkkiä, jotka on koottu suomalaisen metsätoimialan yrityksen haastatteluista.

Optiojärjestelyt HelsinginPörssin pankit- ja rahoitustoimialalistan yrityksissä 1996-2004

Tiivistelmä Tekijä: Veikko Huhta Nimi: Optiojärjestelyt Helsingin Pörssin pankit- ja rahoitustoimialalistan yrityksissä 1996-2004 Osasto: Kauppatieteiden osasto Vuosi: 2005 Pro gradu-tutkielma. Lappeenrannan Teknillinen Yliopisto. 84 sivua, 8 kuviota, 1 taulukko, 5 liitettä. Tarkastajina professori Jaana Sandström ja professori Ulla Kotonen Hakusanat: Optiojärjestelyt, omistajalähtöinen johtaminen, agenttiongelma, pankit- ja rahoitustoimiala Tutkielman tavoitteena oli selvittää, millaisia optiojärjestelyjä HelsinginPörssin pankit- ja rahoitustoimialan yrityksissä on käytössä. Optiojärjestelyjätutkittiin ensinnä tarkastelemalla niiden omistajille aiheuttamaa diluutiovaikutusta. Seuraavaksi tarkastelun kohteena olivat option merkintähinta, optiojärjestelyn voimassaoloaika sekä osinkokorjaus. Optiojärjestelyjen toimivuutta tutkittiin tunnuslukujen ja yrityksen markkina-arvon näkökulmasta. Optiojärjestelyn taustalla olevia tavoitteita tutkittiin omistusrakenteen näkökulmasta. Tutkimuksen kohteena olevat yritykset olivat Sampo Oyj, OKO Oyj, CapMan Oyj sekä Ålandsbanken Ab. Pankit- ja rahoitustoimiala ei ole ns. suurten tuotto-odotusten toimiala. Tasainen osingonjako on optiojärjestelyjen ehtojen valossa omistajille tärkeää. Toimialalla optiojärjestelyjen ensisijainen tehtävä näyttää olevan sitouttaa avainhenkilöitä yritykseen. Vain yhdessä yrityksessä omistajat voivat olla markkina-arvon kehitykseen tyytyväisiä. Omistuksen ja johdon yhdistyminen johtaa optiojärjestelyillä tavoiteltavaan suureen sitouttamisvaikutukseen. Omistusrakenne osoittautui suureksi selittäjäksi optiojärjestelyjen ehtoja asetettaessa.

Géotourisme et utilisation de sites naturels d'intérêt pour les sciences de la Terre: les régions de Crans-Montana-Sierre (Valais, Alpes suisses) et Chamonix-Mont-Blanc (Haute-Savoie, Alpes françaises)

Résumé : Au travers de l'étude des régions de Crans-Montana-Sierre (Valais, Suisse) et de Chamonix-Mont-Blanc (Haute-Savoie, France), cette recherche considère les liens existants entre activités touristiques et sciences de la Terre. Ainsi, les sites géologiques et géomorphologiques pris en compte sont perçus comme ayant non seulement une valeur scientifique, mais aussi un intérêt scénique, culturel et économique. D'un point de vue (géo)touristique, différents modèles d'analyse sont proposés pour expliciter les composantes de l'offre et de la demande et comprendre le cycle de vie des objets étudiés. L'offre que constituent ces sites est tout d'abord présentée afin d'évaluer leurs différents potentiels, ainsi que l'utilisation spatio-temporelle, didactique et économique qui en est faite. Ensuite, les logiques d'acteurs sont analysées au travers des phases de valorisation, d'exploitation et de transformation, dans le but de comprendre les facteurs et les projets d'utilisation les concernant. Enfin, la demande des différents publics cibles, de même que leurs caractéristiques socio-touristiques et (géo)didactiques, sont discutées. Pour ce faire, des méthodes d'inventaire, d'évaluation, d'entretien et de questionnaire ont été utilisées, à différentes échelles d'analyse. On constate d'abord que le pôle des valeurs scénique et économique présente une plus forte mise à contribution, par rapport à l'utilisation didactique. De plus, le niveau de protection des sites ne restreint généralement pas leur exploitation, au contraire du facteur risque. Du point de vue des publics cibles, une forte demande d'explications didactiques est exprimée, s'orientant vers une approche multithématique des potentiels à mettre en valeur; des biens et services de base sont ainsi demandés. Enfin, force est de constater que seuls de grands projets peuvent rendre les activités (géo)touristiques rentables. A l'avenir, sachant que le géotourisme peut répondre à une demande touristique liée au rêve et à l'émotion, l'approche de l'offre devrait intégrer une réflexion en didactique des sciences de la Terre, d'autant que cette forme de tourisme tend à devenir une composante du développement économique régional, notamment en dehors de la saison d'hiver. Idéalement, l'utilisation touristique de la géodiversité devrait s'accompagner d'une politique de protection dynamique, combinant préservation et mise en valeur. A terme, le but ultime de cette entreprise est notamment d'élargir la notion de patrimoine culturel, pour favoriser une approche transdisciplinaire du paysage Abstract : Based on the study of the areas of Crans-Montana-Sierre (Valais, Switzerland) and Chamonix-Mont-Blanc (Haute-Savoie, France), this study considers the links between tourism activities and Earth science. Thus, the studied geological and geomorphological sites have not only a scientific va1ue, but also scenic, cultural and economic value. From a point of view of tourism, different models of analysis are examined in order to explain the components of the supply and the demand, and to understand the life cycles of the considered objects. The primary product of these sites is first presented, in order to assess their different potential as well as their didactic, economic, spatial and temporal use. The stakeholders' behaviour is then analysed to understand the factors and projected use, with the help of the optimisation, exploitation and transformation phases. Finally, the demand of the different target markets as well as their socio-tourist and (geo)didactic characteristics are discussed. To complete this study, methods of census, assessment, interviewing and questionnaire surveying are used, at different scales of analysis. The main results appear to demonstrate that the scenic and economic values present a higher value relative to the didactic use. Moreover, the required conservation measures for the studied sites do not generally restrict the use, on the contrary to the "risk" factor. From the point of view of the target market, a relevant requirement for explanatory commentary is expressed and tends towards an approach optimising different themes to utilise potential; basic popular goods and services are also requested. Finally, it is clearly demonstrated that only relevant projects are able to make this kind of activity profitable. For the future, geotourism may be marketed to a tourist demand for imagination and emotion. Consequently, the product approach should integrate a reflection on Earth science popularisation given that this branch of tourism tends to receive a component of the economic and regional development, notably during the summer period. However, the use of geodiversity should include a concept of dynamic management, taking into account conservation as well as tourism development. Thus, the final aim of this process is to r,r'iden the notion of cultural heritage, in order to stimulate a multidisciplinary approach to the landscape.

Application des méthodes géophysiques à l'étude de deux sites (Kappelen et Grenchen) de l'aquifère poreux complexe du Seeland

L'aquifère du Seeland représente une richesse en ressources hydriques qu'il est impératif de préserver contre tout risque de détérioration. Cet aquifère prolifique est constitué principalement de sédiments alluviaux post-glaciaires (graviers, sables et limons). Il est soumis aux contraintes environnementales des pratiques d'agriculture intensive, du réseau routier, des villes et de leurs activités industrielles. La connaissance optimale de ces ressources est donc primordiale pour leur protection. Dans cette optique, deux sites Kappelen et Grenchen représentatifs de l'aquifère du Seeland ont été étudiés. L'objectif de ce travail est de caractériser d'un point de vue hydrogéophysique l'aquifère au niveau de ces deux sites, c'est-à-dire, comprendre la dynamique des écoulements souterrains par l'application des méthodes électriques de surface associées aux diagraphies en intégrant des méthodes hydrogéologiques. Pour le site de Kappelen, les méthodes électriques de surface ont permis d'identifier les différents faciès géoélectriques en présence et de mettre en évidence leur disposition en une structure tabulaire et horizontale. Il s'agit d'un aquifère libre constitué d'une série de graviers allant jusqu'à 15 m de profondeur reposant sur de la moraine argileuse. Les diagraphies électriques, nucléaires et du fluide ont servis à la détermination des caractéristiques pétrophysiques et hydrauliques de l'aquifère qui contrôlent son comportement hydrodynamique. Les graviers aquifères de Kappelen présentent deux minéraux dominants: quartz et calcite. Les analyses minéralogiques indiquent que ces deux éléments constituent 65 à 75% de la matrice. La porosité totale obtenue par les diagraphies nucléaires varie de 20 à 30 %, et de 22 à 29 % par diagraphies électrique. Avec les faibles valeurs de Gamma Ray ces résultats indiquent que l'aquifère des graviers de Kappelen est dépourvu d'argile minéralogique. La perméabilité obtenue par diagraphies du fluide varie de 3.10-4 à 5.10-2 m/s, et par essais de pompage de 10-4 à 10-2 m/s. Les résultats des analyses granulométriques indiquent une hétérogénéité granulométrique au niveau des graviers aquifères. La fraction de sables, sables très fins, silts et limons constitue de 10 à 40 %. Ces éléments jouent un rôle important dans le comportement hydraulique de l'aquifère. La porosité efficace de 11 à 25% estimée à partir des résultats des analyses granulométriques suppose que les zones les plus perméables correspondent aux zones les plus graveleuses du site. Etablie sur le site de Kappelen, cette méthodologie a été utilisée sur le site de Grenchen. Les méthodes électriques de surface indiquent que l'aquifère captif de Grenchen est constitué des sables silteux comprenant des passages sableux, encadrés par des silts argileux imperméables. L'aquifère de Grenchen est disposé dans une structure relativement tabulaire et horizontale. Son épaisseur totale peut atteindre les 25 m vers le sud et le sud ouest ou les passages sableux sont les plus importants. La détermination des caractéristiques pétrophysiques et hydrauliques s'est faite à l'aide des diagraphies. Les intensités Gamma Ray varient de 30 à 100 cps, les plus fortes valeurs n'indiquent qu'une présence d'éléments argileux mais pas de bancs d'argile. Les porosités totales de 15 à 25% et les densités globales de 2.25 à 2.45 g/cm3 indiquent que la phase minérale (matrice) est composée essentiellement de quartz et de calcaire. Les densités de matrice varient entre 2.65 et 2.75 g/cm3. La perméabilité varie de 2 10-6 à 5 10-4 m/s. La surestimation des porosités totales à partir des diagraphies électriques de 25 à 42% est due à la présence d'argiles. -- The vast alluvial Seeland aquifer system in northwestern Switzerland is subjected to environmental challenges due to intensive agriculture, roads, cities and industrial activities. Optimal knowledge of the hydrological resources of this aquifer system is therefore important for their protection. Two representative sites, Kappelen and Grenchen, of the Seeland aquifer were investigated using surface-based geoelectric methods and geophysical borehole logging methods. By integrating of hydrogeological and hydrogeophysical methods, a reliable characterization of the aquifer system at these two sites can be performed in order to better understand the governing flow and transport process. At the Kappelen site, surface-based geoelectric methods allowed to identify various geoelectric facies and highlighted their tabular and horizontal structure. It is an unconfined aquifer made up of 15 m thick gravels with an important sandy fraction and bounded by a shaly glacial aquitard. Electrical and nuclear logging measurements allow for constraining the petrophysical and hydrological parameters of saturated gravels. Results indicate that in agreement with mineralogical analyses, matrix of the probed formations is dominated by quartz and calcite with densities of 2.65 and 2.71 g/cc, respectively. These two minerals constitute approximately 65 to 75 % of the mineral matrix. Matrix density values vary from 2.60 to 2.75 g/cc. Total porosity values obtained from nuclear logs range from 20 to 30 % and are consistent with those obtained from electrical logs ranging from 22 to 29 %. Together with the inherently low natural gamma radiation and the matrix density values obtained from other nuclear logging measurements, this indicates that at Kappelen site the aquifer is essentially devoid of clay. Hydraulic conductivity values obtained by the Dilution Technique vary between 3.10-4 and 5.10-2 m/s, while pumping tests give values ranging from 10-4 to 10-2 m/s. Grain size analysis of gravel samples collected from boreholes cores reveal significant granulometric heterogeneity of these deposits. Calculations based on these granulometric data have shown that the sand-, silt- and shale-sized fractions constitute between 10 and 40 % of the sample mass. The presence of these fine elements in general and their spatial distribution in particular are important as they largely control the distribution of the total and effective porosity as well as the hydraulic conductivity. Effective porosity values ranging from 11 to 25% estimated from grain size analyses indicate that the zones of higher hydraulic conductivity values correspond to the zones dominated by gravels. The methodology established at the Kappelen site was then applied to the Grenchen site. Results from surface-based geoelectric measurements indicate that it is a confined aquifer made up predominantly of shaly sands with intercalated sand lenses confined impermeable shally clay. The Grenchen confined aquifer has a relatively tabular and horizontal structure with a maximum thickness of 25 m in the south and the southwest with important sand passages. Petrophysical and hydrological characteristics were performed using electrical and nuclear logging. Natural gamma radiation values ranging from 30 to 100 cps indicate presence of a clay fraction but not of pure clay layers. Total porosity values obtained from electrical logs vary form 25 to 42%, whereas those obtained from nuclear logs values vary from 15 to 25%. This over-estimation confirms presences of clays. Density values obtained from nuclear logs varying from 2.25 to 2.45 g/cc in conjunction with the total porosity values indicate that the dominating matrix minerals are quartz and calcite. Matrix density values vary between 2.65 and 2.75 g/cc. Hydraulic conductivity values obtained by the Dilution Technique vary from 2 10-6 to 5 10-4 m/s.

Database Rights in Safe European Home: The Path to More Rigorous Protection of Information

1. Introduction "The one that has compiled ... a database, the collection, securing the validity or presentation of which has required an essential investment, has the sole right to control the content over the whole work or over either a qualitatively or quantitatively substantial part of the work both by means of reproduction and by making them available to the public", Finnish Copyright Act, section 49.1 These are the laconic words that implemented the much-awaited and hotly debated European Community Directive on the legal protection of databases,2 the EDD, into Finnish Copyright legislation in 1998. Now in the year 2005, after more than half a decade of the domestic implementation it is yet uncertain as to the proper meaning and construction of the convoluted qualitative criteria the current legislation employs as a prerequisite for the database protection both in Finland and within the European Union. Further, this opaque Pan-European instrument has the potential of bringing about a number of far-reaching economic and cultural ramifications, which have remained largely uncharted or unobserved. Thus the task of understanding this particular and currently peculiarly European new intellectual property regime is twofold: first, to understand the mechanics and functioning of the EDD and second, to realise the potential and risks inherent in the new legislation in economic, cultural and societal dimensions. 2. Subject-matter of the study: basic issues The first part of the task mentioned above is straightforward: questions such as what is meant by the key concepts triggering the functioning of the EDD such as presentation of independent information, what constitutes an essential investment in acquiring data and when the reproduction of a given database reaches either qualitatively or quantitatively the threshold of substantiality before the right-holder of a database can avail himself of the remedies provided by the statutory framework remain unclear and call for a careful analysis. As for second task, it is already obvious that the practical importance of the legal protection providedby the database right is in the rapid increase. The accelerating transformationof information into digital form is an existing fact, not merely a reflection of a shape of things to come in the future. To take a simple example, the digitisation of a map, traditionally in paper format and protected by copyright, can provide the consumer a markedly easier and faster access to the wanted material and the price can be, depending on the current state of the marketplace, cheaper than that of the traditional form or even free by means of public lending libraries providing access to the information online. This also renders it possible for authors and publishers to make available and sell their products to markedly larger, international markets while the production and distribution costs can be kept at minimum due to the new electronic production, marketing and distributionmechanisms to mention a few. The troublesome side is for authors and publishers the vastly enhanced potential for illegal copying by electronic means, producing numerous virtually identical copies at speed. The fear of illegal copying canlead to stark technical protection that in turn can dampen down the demand for information goods and services and furthermore, efficiently hamper the right of access to the materials available lawfully in electronic form and thus weaken the possibility of access to information, education and the cultural heritage of anation or nations, a condition precedent for a functioning democracy. 3. Particular issues in Digital Economy and Information Networks All what is said above applies a fortiori to the databases. As a result of the ubiquity of the Internet and the pending breakthrough of Mobile Internet, peer-to-peer Networks, Localand Wide Local Area Networks, a rapidly increasing amount of information not protected by traditional copyright, such as various lists, catalogues and tables,3previously protected partially by the old section 49 of the Finnish Copyright act are available free or for consideration in the Internet, and by the same token importantly, numerous databases are collected in order to enable the marketing, tendering and selling products and services in above mentioned networks. Databases and the information embedded therein constitutes a pivotal element in virtually any commercial operation including product and service development, scientific research and education. A poignant but not instantaneously an obvious example of this is a database consisting of physical coordinates of a certain selected group of customers for marketing purposes through cellular phones, laptops and several handheld or vehicle-based devices connected online. These practical needs call for answer to a plethora of questions already outlined above: Has thecollection and securing the validity of this information required an essential input? What qualifies as a quantitatively or qualitatively significant investment? According to the Directive, the database comprises works, information and other independent materials, which are arranged in systematic or methodical way andare individually accessible by electronic or other means. Under what circumstances then, are the materials regarded as arranged in systematic or methodical way? Only when the protected elements of a database are established, the question concerning the scope of protection becomes acute. In digital context, the traditional notions of reproduction and making available to the public of digital materials seem to fit ill or lead into interpretations that are at variance with analogous domain as regards the lawful and illegal uses of information. This may well interfere with or rework the way in which the commercial and other operators have to establish themselves and function in the existing value networks of information products and services. 4. International sphere After the expiry of the implementation period for the European Community Directive on legal protection of databases, the goals of the Directive must have been consolidated into the domestic legislations of the current twenty-five Member States within the European Union. On one hand, these fundamental questions readily imply that the problemsrelated to correct construction of the Directive underlying the domestic legislation transpire the national boundaries. On the other hand, the disputes arisingon account of the implementation and interpretation of the Directive on the European level attract significance domestically. Consequently, the guidelines on correct interpretation of the Directive importing the practical, business-oriented solutions may well have application on European level. This underlines the exigency for a thorough analysis on the implications of the meaning and potential scope of Database protection in Finland and the European Union. This position hasto be contrasted with the larger, international sphere, which in early 2005 does differ markedly from European Union stance, directly having a negative effect on international trade particularly in digital content. A particular case in point is the USA, a database producer primus inter pares, not at least yet having aSui Generis database regime or its kin, while both the political and academic discourse on the matter abounds. 5. The objectives of the study The above mentioned background with its several open issues calls for the detailed study of thefollowing questions: -What is a database-at-law and when is a database protected by intellectual property rights, particularly by the European database regime?What is the international situation? -How is a database protected and what is its relation with other intellectual property regimes, particularly in the Digital context? -The opportunities and threats provided by current protection to creators, users and the society as a whole, including the commercial and cultural implications? -The difficult question on relation of the Database protection and protection of factual information as such. 6. Dsiposition The Study, in purporting to analyse and cast light on the questions above, is divided into three mainparts. The first part has the purpose of introducing the political and rationalbackground and subsequent legislative evolution path of the European database protection, reflected against the international backdrop on the issue. An introduction to databases, originally a vehicle of modern computing and information andcommunication technology, is also incorporated. The second part sets out the chosen and existing two-tier model of the database protection, reviewing both itscopyright and Sui Generis right facets in detail together with the emergent application of the machinery in real-life societal and particularly commercial context. Furthermore, a general outline of copyright, relevant in context of copyright databases is provided. For purposes of further comparison, a chapter on the precursor of Sui Generi, database right, the Nordic catalogue rule also ensues. The third and final part analyses the positive and negative impact of the database protection system and attempts to scrutinize the implications further in the future with some caveats and tentative recommendations, in particular as regards the convoluted issue concerning the IPR protection of information per se, a new tenet in the domain of copyright and related rights.
