Selected Aspects Related to Pre-development Stages of International Software projects. Case of Finland and Russia

The question of Pilot Project creation, due to support pre-development stage of software product elaboration, nowadays might be used as an approach, which allows improving the whole scheme of information technology project running. This subject is not new, but till now no model has been presented, which gives deep description of this important stage on the early phase of project. This Master's Thesis represents the research's results and findings concerning the pre-development study from the Software Engineering point of view. The aspects of feasibility study, pilot prototype developments are analyzed in this paper. As the result, the technique of Pilot Project is formulated and scheme has been presented. The experimental part is focused on particular area Pilot Project scheme's implementation- Internationally Distributed Software projects. The specific characteristic, aspects, obstacles, advantages and disadvantages are considered on the example of cross border region of Russia and Finland. The real case of Pilot Project technique implementation is given.

The tightness performance of pre-formed trays as package

Suojakaasupakkaaminen (MAP) on yleistynyt viime aikoina, koska sen avulla voidaan säilöä tuoreita tai vähän käsiteltyjä elintarvikkeita pidempään. Suurin syy hyllyiän pidentymiseen on hiilidioksidin aiheuttama mikrobien kasvun hidastuminen. Toisaalta huolena on patogeenisten mikrobien lisääntyminen anaerobisissa olosuhteissa. Pidempi säilyvyys voidaan saavuttaa myös käyttämällä vähemmän lisä- ja säilöntäaineita. Samalla suojakaasupakkaaminen kuitenkin vähentää myös pilaantuneiden tuotteiden määrää. Eniten suojakaasua käytetään lihan pakkaamisessa. Suojakaasupakkaamisessa elintarvikepakkaukseen syötetään normaalista huoneilmasta poikkeava kaasuseos. Pääasiassa kaasuseos koostuu hiilidioksidista, hapesta ja typestä. Lisäksi voidaan käyttää pieniä määriä hiilimonoksidia, argonia ja rikkidioksidia. Kaasuseoksen koostumus määräytyy elintarvikkeiden ominaisuuksien ja vaatimusten perusteella. Halutun kaasukoostumuksen tulee säilyä pakkauksessa muutamasta päivästä muutamaan kuukauteen riippuen elintarvikkeesta. Siksi tärkein pakkaukselta vaadittava ominaisuus on riittävä kaasutiiveys ja erityisesti hapenläpäisevyys. Koska suurin osa suojakaasupakkauksista on tällä hetkellä muovisia, tutkittiin kokeellisessa osiossa kartonkipakkausten tiiveysominaisuuksia. Kokeet tehtiin vertailemalla erilaisten vuoka- ja kansimateriaalien vaikutusta pakkausten tiiveyteen. Vuokien onnistuminen oli suurin yksittäinen tuloksiin vaikuttanut tekijä. Epäonnistuneen vuoan vaikutukset näkyivät myös saumauksessa, koska saumaustyökalun ja vuoan piti sopia yhteen. Lisäksi näkymättömät mikroreiät hankaloittivat todellisten vuotokohtien paikallistamista. Vuototestausten perusteella materiaaleille löydettiin kuitenkin viitteelliset optimiparametrit. Tärkein saumauksessa vaikuttanut tekijä oli sopivan saumauslämpötilan valinta. Prässättyjen vuokien laatu oli epätasainen. Siksi erityisesti rinnakkaisten kansitus- ja hapenläpäisymittausten väliset erot olivat merkitseviä. Lisäksi prässäys laski materiaalien hapenläpäisyominaisuuksia. Yksittäisten vuokien tiiveysominaisuudet täyttivät kuitenkin kaupallisille kaasupakkauksille asetetut vaatimukset. Vesihöyrynläpäisevyydessä materiaalin vesihöyrynläpäisy oli merkittävämpää kuin vesihöyryn kulkeutuminen vuotokohtien tai epäonnistuneiden saumojen kautta.

Bordetella pertussis - Vaccination and Strain Variation

Pertussis or whooping cough is a highly contagious vaccine-preventable disease of the human respiratory tract caused by the Bordetella pertussis bacteria. In Finland, pertussis vaccinations were started in 1952 leading to a dramatic decrease in the morbidity and mortality. In the late 1990s, the incidence of pertussis increased despite the high vaccination coverage. Strain variation has been connected to the re-emergence of pertussis in countries with long history of pertussis vaccination. In 2005, the pertussis vaccine and the vaccination schedule were changed in Finland. The molecular epidemiology and the strain variation of the B. pertussis isolates were examined in Finland and in countries with similar (France) and different (Sweden) vaccination history. Continuous evolution of the B. pertussis population in Finland was observed since the 1950s, and the recently circulating isolates were antigenically different from the vaccine strains. Comparison of the circulating isolates from Finland, France and Sweden did not refer to significant differences. Certain type of strains noticed in France already in 1994 mainly caused the recent epidemics in Sweden (1999) and in Finland (2003-4). On several occasions, a new type of strains first appeared in Sweden and some years later in Finland. The B. pertussis isolates from the infants were shown to be similar to those from the other age groups. It is suggested that the strains originate from the same reservoir among adolescents and adults. The strain variation does not seem to have a major effect on the morbidity among recently vaccinated individuals, but it might play a role among those who are in the waning phase of immunity. The incidence of pertussis in Finland has remained low since the change of the vaccination programme. This might be related to the epidemic nature of pertussis and the near future will show the real effectiveness of the new vaccination programme. At present, many infants are infected because they are too young to be immunised with the current schedule. New strategies or vaccines are needed to protect those who are the most vulnerable.

Nocturnal Transcutaneous Carbon Dioxide and Early Changes in Atherosclerosis in Pre- and Postmenopausal Women

The risk of cardiovascular diseases and sleep-disordered breathing increases after menopause. This cross-sectional study focuses on overnight transcutaneous carbon dioxide (TcCO₂) measurements and their power to predict changes in the early markers of cardiovascular and metabolic diseases. The endothelial function of the brachial artery, the intima-media thickness of the carotid artery, blood pressure, glycosylated hemoglobin A1C and plasma levels of cholesterols and triglycerides were used as markers of cardiovascular and metabolic diseases. The study subjects consisted of healthy premenopausal women of 46 years of age and postmenopausal women of 56 years of age. From wakefulness to sleep, the TcCO₂ levels increased more in postmenopausal women than in premenopausal women. In estrogen-users the increase in TcCO₂ levels was even more pronounced than in other postmenopausal women. From the dynamic behaviour of the nocturnal TcCO₂ signal, several important features were detected. These TcCO₂ features had a remarkable role in the prediction of endothelial dysfunction and thickening of the carotid wall in healthy premenopausal women. In addition, these TcCO₂ features were linked with blood pressure, lipid profile and glucose balance in postmenopausal women. The nocturnal TcCO₂ profile seems to contain significant information, which is associated with early changes in cardiovascular diseases in middle-aged women. TcCO₂ might not only measure the tissue carbon dioxide levels, but the TcCO₂ signal variation may also reflect peripheral vasodynamic events caused by increased sympathetic activity during sleep.
