Suomalaisten pienten ja keskisuurten yritysten etabloituminen Kiinan markkinoille

Tutkielman tavoitteena oli lähestyä Kiinan markkinoita suomalaisten pienten ja keskisuurten yritysten (pk-yritys) näkökulmasta. Tutkielman päätavoitteena oli käydä läpi niitä tekijöitä, joiden tiedostaminen auttaa suomalaisia pk-yrityksiä etabloitumaan Kiinan markkinoille. Tutkielman tarkoituksena oli myös tuottaa oleellista yleistietoa Kiinasta liiketoimintaympäristönä, minkä etsiminen on usein hyvin aikaakuluttavaa. Yleistiedon pohjalta pk-yritykset voivat punnita soveltuuko uusi ja houkutteleva markkina-alue niille. Tutkielma on luonteeltaan lähinnä kuvaileva markkinatutkimus, joka perustuu jo olemassa olevaan tietoon Kiinan markkinoista. Tutkielma toteutettiin ns. kirjoituspöytätutkimuksena ja suurin osa tiedosta on sekundaarista, yleistietoa liiketoimintaympäristöstä. Tutkielman lähdeaineistona käytettiin mahdollisimman uutta koti- ja ulkomaista kirjallisuutta, artikkeleita sekä seminaareissa esitettyjä tutkimuspapereita. Lähdeaineiston käsittely perustui aineistolähtöiseen analyysiin. Analyysin avulla pyrittiin tiivistämään aineisto ja kasvattamaan sen informaatioarvoa luomalla hajanaisesta aineistosta selkeää ja mielekästä, kadottamatta silti sen sisältämää informaatiota. Tässä tutkielmassa esiin tulleiden tekijöiden perusteella vaikuttaa siltä, että suomalaisilla pk-yrityksillä on huomattavia kehitys- ja kasvumahdollisuuksia Kiinan markkinoilla. Parhaat mahdollisuudet menestyä Kiinan markkinoilla on niillä yrityksillä, jotka omaavat kansainvälistä kokemusta, ovat teknologiaorientoituneita ja pitkälle erikoistuneita omalla toimialallaan. Menestyminen edellyttää myös hyvää paikallista markkinatuntemusta, kykyä solmia hyviä kontakteja paikallisiin viranomaisiin ja markkinoilla toimijoihin sekä valmiutta sitoutua pitkällä aikajänteellä Kiinan markkinoille.

Utilización de software de corrección automática en el campo de las ciencias de la salud

We live in an era of profound changes in university education. The implementation of Bologna plan has led us to raise new teaching methodologies, to review the role of the student, competency assessment, the incorporation of ICT. Unthinkable acts, one or two decade ago. The TIC concept is very broad and is attributed to the media, processes and content usage. Inside the supports and platforms, we stress tools that allow automatic correction of exercises, because they are instruments of great educational value because instantly they assess students and provide instant feedback about the knowledge that they have either as message support or note. If the power of these tools, we add the Internet, using e-learning environment, the results allow us to work, edit, evaluate, resolve doubts, and so on, anywhere, anytime. We present part of a platform and the results of its use in the field of health sciences

Editor i disseny d'interiors

L’OpenGL és un motor 3D que s’utilitza com a lligam entre el software i el hardware gràfic. Actualment és una de les tecnologies més utilitzades en el disseny d’aplicacions 3D. El treball està realitzat amb el programa Visual C++, que és el més recomanat per al desenvolupament d’aplicacions OpenGL. L’objectiu principal d’aquest treball és aprendre a programar amb aquest tipus de tecnologia que no hem estudiat durant el període de carrera. Un altre objectiu del treball era trobar una funció útil i pràctica per a l’aplicació i ens vam decantar per a realitzar un editor d’habitacions per un botiga o empresa de mobles. L’usuari pot de forma molt ràpida i senzilla dibuixar com és l’habitació que vol decorar de forma totalment personalitzada. El programa li generarà l’habitació en tres dimensions i amb els materials que s’han escollit (terra, parets, portes…). Després pot editar-hi mobles personalitzats o pertanyents a la llibreria del programa. El programa incorpora també una base de dades per a l’empresa que ens portarà la gestió de clients, habitacions, textures i mobles (permet ampliar la llibreria del programa). Un cop acabada l’habitació el programa ens hi permet fer una visita de forma interactiva i generar-ne la factura entre altres funcions. La conclusió principal després d’haver acabat aquest projecte, és que a part d’haver après OpenGL, hem aconseguit realitzar una aplicació molt pràctica de cares al disseny d’interiorisme.

Domo Hogar, Automatització de l'habitatge

En aquest projecte crearem un sistema per automatitzar els diferents dispositius que podem trobar en una casa. En primer lloc dissenyarem el hardware que serà el sistema nerviós des del que controlarem els dispositius a través del port USB d’un ordinador. Aquest sistema nerviós serà el punt d’interconnexió entre els dispositius de la casa i l’ordinador central que els controlarà. A nivell de hardware, a més a més del mòdul d’entrades i sortides d’interconnexió amb els dispositius que hem esmentat, ens trobem amb la necessitat d’instal•lar un ordinador central i diferents aparells repartits per la casa per poder realitzar les nostres necessitats (accions dels diferents dispositius) des de qualsevol punt de la casa. Amb aquests requeriments haurem d’estudiar les diferents possibilitats per fer el nostre sistema el màxim d’eficaç possible. Finalitzat l’estudi del hardware necessari pel nostre projecte, el següent pas és dissenyar el software. Aquest software serà l’aplicació encarregada de controlar tot el maquinari que hem dissenyat anteriorment i rebrà el nom de DOMO HOGAR. Aquest estarà format per dos programes diferents, DOMO HOGAR SERVER i DOMO HOGAR TERMINAL, cadascun d’ells amb unes funcions específiques. DOMO HOGAR SERVER serà l’aplicació que residirà a l’ordinador central i que permetrà a l’administrador gestionar totes les parts de les que forma part el nostre sistema: dispositius, tasques, pre-condicions, etc... També des d’aquesta aplicació editarem el panell tàctil que mostrarem des dels diferents terminals de l’habitatge. Per últim, aquesta aplicació també s’encarregarà de resoldre les peticions que farem, tant de l’ordinador central com dels terminals, i gestionar les diferents sortides en funció de l’acció a realitzar. Paral•lelament ens trobarem l’aplicació DOMO HOGAR TERMINAL que residirà en cada un dels terminals que hi hagi a la casa. Aquesta aplicació s’inicialitzarà llegint la configuració del panell tàctil de la base de dades de l’aplicació servidor resident a l’ordinador central i reconstruint una rèplica d’aquest panell tàctil. Finalment des d’aquesta aplicació terminal podrem donar ordres que seran emmagatzemades a la llista de tasques pendents de l’ordinador central perquè les resolgui des de l’aplicació del servidor. DOMO HOGAR ha estat creat per facilitar i confortar la vida quotidiana de les persones agilitzant el nostre dia a dia i permetent-nos invertir el nostre temps en les coses realment importants.

Disseny i implementació d'una pàgina web de subhastes

Amb la situació econòmica actual pot ser interessant poder vendre objectes que ja no s’utilitzen i també poder-ne comprar de segona mà. Amb aquesta idea sorgeix el projecte de crear una pàgina de subhastes online on la gent pugui comerciar amb les coses que ja no necessita. Tenint en compte el concepte inicial, el propietari de la pàgina no rebrà cap retribució ni percentatge de cada subhasta, tot l’import serà pel venedor. L’objectiu principal és el de poder oferir un lloc on després de registrar-se, els usuaris puguin veure i pujar per els articles que altres persones estan subhastant i també la possibilitat de crear les seves pròpies subhastes. Cada usuari disposarà d’un espai personal on veure les subhastes amb les que ha interactuat i així no perdre-les de vista i també on poder veure en cada moment l’estat de les subhastes que ha creat. La vista d’una subhasta s’actualitzarà automàticament sense haver de recarregar la pàgina i si algú puja durant l’últim minut la subhasta s’allargarà un minut més per evitar puges a l’últim moment i així maximitzar el preu final. Hi haurà un administrador que serà l’encarregat de gestionar el bon funcionament de la pàgina amb permís per afegir, editar, consultar i eliminar tota la informació disponible. Per portar a terme el projecte s’ha utilitzat PHP per la part de programació i MySQL com a sistema gestor de bases de dades.

Environmental Challenges in the Joint Border Area of Norway, Finland and Russia

This report examines the human impact on the subarctic environment of the joint border area of Norway, Finland and Russia. The aim is to present the current state and recent changes that have taken place in the region. The main threat to the environment is the Pechenganikel mining and metallurgical industrial combine in the towns of Nikel and Zapolyarny in the Kola Peninsula. Emissions from this complex include high levels of heavy metals, persistent organic pollutants and sulfur dioxide. Pollution, along with climate change, water level regulation and other anthropogenic effects, has affected the aquatic ecosystems in the joint border area. The main heavy metals in the area are copper and nickel, the highest concentrations of which are measured near the combine. Direct discharge of sewage into the river continues and airborne heavy metal particles are also deposited to areas farther away. Climate changeinduced increase in temperature and precipitation in the Kola Peninsula is evident. Water level regulation with seven hydropower plants in the Pasvik River have changed it into a series of lakes and lake-like reservoirs. This report discusses modelling, which was enabled to estimate the effect of climate change on Lake Inarijärvi and the Pasvik River hydrology, water level fluctuation and ecology and to follow the sulfur dioxide emissions emitted from the Pechenganikel. Effects of pollution on the nature and concentrations of the main pollutants were studied and climate change in the border area and its effects on the ecology were estimated. Also the effects of water level regulation on the ecological status of the aquatic ecosystems were addressed.

Nichesourcing The Uralic Languages For The Benefit Of Linguistic Research And Lingual Societies

The emerging technologies have recently challenged the libraries to reconsider their role as a mere mediator between the collections, researchers, and wider audiences (Sula, 2013), and libraries, especially the nationwide institutions like national libraries, haven’t always managed to face the challenge (Nygren et al., 2014). In the Digitization Project of Kindred Languages, the National Library of Finland has become a node that connects the partners to interplay and work for shared goals and objectives. In this paper, I will be drawing a picture of the crowdsourcing methods that have been established during the project to support both linguistic research and lingual diversity. The National Library of Finland has been executing the Digitization Project of Kindred Languages since 2012. The project seeks to digitize and publish approximately 1,200 monograph titles and more than 100 newspapers titles in various, and in some cases endangered Uralic languages. Once the digitization has been completed in 2015, the Fenno-Ugrica online collection will consist of 110,000 monograph pages and around 90,000 newspaper pages to which all users will have open access regardless of their place of residence. The majority of the digitized literature was originally published in the 1920s and 1930s in the Soviet Union, and it was the genesis and consolidation period of literary languages. This was the era when many Uralic languages were converted into media of popular education, enlightenment, and dissemination of information pertinent to the developing political agenda of the Soviet state. The ‘deluge’ of popular literature in the 1920s to 1930s suddenly challenged the lexical orthographic norms of the limited ecclesiastical publications from the 1880s onward. Newspapers were now written in orthographies and in word forms that the locals would understand. Textbooks were written to address the separate needs of both adults and children. New concepts were introduced in the language. This was the beginning of a renaissance and period of enlightenment (Rueter, 2013). The linguistically oriented population can also find writings to their delight, especially lexical items specific to a given publication, and orthographically documented specifics of phonetics. The project is financially supported by the Kone Foundation in Helsinki and is part of the Foundation’s Language Programme. One of the key objectives of the Kone Foundation Language Programme is to support a culture of openness and interaction in linguistic research, but also to promote citizen science as a tool for the participation of the language community in research. In addition to sharing this aspiration, our objective within the Language Programme is to make sure that old and new corpora in Uralic languages are made available for the open and interactive use of the academic community as well as the language societies. Wordlists are available in 17 languages, but without tokenization, lemmatization, and so on. This approach was verified with the scholars, and we consider the wordlists as raw data for linguists. Our data is used for creating the morphological analyzers and online dictionaries at the Helsinki and Tromsø Universities, for instance. In order to reach the targets, we will produce not only the digitized materials but also their development tools for supporting linguistic research and citizen science. The Digitization Project of Kindred Languages is thus linked with the research of language technology. The mission is to improve the usage and usability of digitized content. During the project, we have advanced methods that will refine the raw data for further use, especially in the linguistic research. How does the library meet the objectives, which appears to be beyond its traditional playground? The written materials from this period are a gold mine, so how could we retrieve these hidden treasures of languages out of the stack that contains more than 200,000 pages of literature in various Uralic languages? The problem is that the machined-encoded text (OCR) contains often too many mistakes to be used as such in research. The mistakes in OCRed texts must be corrected. For enhancing the OCRed texts, the National Library of Finland developed an open-source code OCR editor that enabled the editing of machine-encoded text for the benefit of linguistic research. This tool was necessary to implement, since these rare and peripheral prints did often include already perished characters, which are sadly neglected by the modern OCR software developers, but belong to the historical context of kindred languages and thus are an essential part of the linguistic heritage (van Hemel, 2014). Our crowdsourcing tool application is essentially an editor of Alto XML format. It consists of a back-end for managing users, permissions, and files, communicating through a REST API with a front-end interface—that is, the actual editor for correcting the OCRed text. The enhanced XML files can be retrieved from the Fenno-Ugrica collection for further purposes. Could the crowd do this work to support the academic research? The challenge in crowdsourcing lies in its nature. The targets in the traditional crowdsourcing have often been split into several microtasks that do not require any special skills from the anonymous people, a faceless crowd. This way of crowdsourcing may produce quantitative results, but from the research’s point of view, there is a danger that the needs of linguists are not necessarily met. Also, the remarkable downside is the lack of shared goal or the social affinity. There is no reward in the traditional methods of crowdsourcing (de Boer et al., 2012). Also, there has been criticism that digital humanities makes the humanities too data-driven and oriented towards quantitative methods, losing the values of critical qualitative methods (Fish, 2012). And on top of that, the downsides of the traditional crowdsourcing become more imminent when you leave the Anglophone world. Our potential crowd is geographically scattered in Russia. This crowd is linguistically heterogeneous, speaking 17 different languages. In many cases languages are close to extinction or longing for language revitalization, and the native speakers do not always have Internet access, so an open call for crowdsourcing would not have produced appeasing results for linguists. Thus, one has to identify carefully the potential niches to complete the needed tasks. When using the help of a crowd in a project that is aiming to support both linguistic research and survival of endangered languages, the approach has to be a different one. In nichesourcing, the tasks are distributed amongst a small crowd of citizen scientists (communities). Although communities provide smaller pools to draw resources, their specific richness in skill is suited for complex tasks with high-quality product expectations found in nichesourcing. Communities have a purpose and identity, and their regular interaction engenders social trust and reputation. These communities can correspond to research more precisely (de Boer et al., 2012). Instead of repetitive and rather trivial tasks, we are trying to utilize the knowledge and skills of citizen scientists to provide qualitative results. In nichesourcing, we hand in such assignments that would precisely fill the gaps in linguistic research. A typical task would be editing and collecting the words in such fields of vocabularies where the researchers do require more information. For instance, there is lack of Hill Mari words and terminology in anatomy. We have digitized the books in medicine, and we could try to track the words related to human organs by assigning the citizen scientists to edit and collect words with the OCR editor. From the nichesourcing’s perspective, it is essential that altruism play a central role when the language communities are involved. In nichesourcing, our goal is to reach a certain level of interplay, where the language communities would benefit from the results. For instance, the corrected words in Ingrian will be added to an online dictionary, which is made freely available for the public, so the society can benefit, too. This objective of interplay can be understood as an aspiration to support the endangered languages and the maintenance of lingual diversity, but also as a servant of ‘two masters’: research and society.

Nichesourcing for the benefit of linguistic research and native speakers

The National Library of Finland is implementing the Digitization Project of Kindred Languages in 2012–16. Within the project we will digitize materials in the Uralic languages as well as develop tools to support linguistic research and citizen science. Through this project, researchers will gain access to new corpora 329 and to which all users will have open access regardless of their place of residence. Our objective is to make sure that the new corpora are made available for the open and interactive use of both the academic community and the language societies as a whole. The project seeks to digitize and publish approximately 1200 monograph titles and more than 100 newspapers titles in various Uralic languages. The digitization will be completed by the early of 2015, when the Fenno-Ugrica collection would contain around 200 000 pages of editable text. The researchers cannot spend so much time with the material that they could retrieve a satisfactory amount of edited words, so the participation of a crowd in editing work is needed. Often the targets in crowdsourcing have been split into several microtasks that do not require any special skills from the anonymous people, a faceless crowd. This way of crowdsourcing may produce quantitative results, but from the research’s point of view, there is a danger that the needs of linguistic research are not necessarily met. Also, the number of pages is too high to deal with. The remarkable downside is the lack of shared goal or social affinity. There is no reward in traditional methods of crowdsourcing. Nichesourcing is a specific type of crowdsourcing where tasks are distributed amongst a small crowd of citizen scientists (communities). Although communities provide smaller pools to draw resources, their specific richness in skill is suited for the complex tasks with high-quality product expectations found in nichesourcing. Communities have purpose, identity and their regular interactions engenders social trust and reputation. These communities can correspond to research more precisely. Instead of repetitive and rather trivial tasks, we are trying to utilize the knowledge and skills of citizen scientists to provide qualitative results. Some selection must be made, since we are not aiming to correct all 200,000 pages which we have digitized, but give such assignments to citizen scientists that would precisely fill the gaps in linguistic research. A typical task would editing and collecting the words in such fields of vocabularies, where the researchers do require more information. For instance, there’s a lack of Hill Mari words in anatomy. We have digitized the books in medicine and we could try to track the words related to human organs by assigning the citizen scientists to edit and collect words with OCR editor. From the nichesourcing’s perspective, it is essential that the altruism plays a central role, when the language communities involve. Upon the nichesourcing, our goal is to reach a certain level of interplay, where the language communities would benefit on the results. For instance, the corrected words in Ingrian will be added onto the online dictionary, which is made freely available for the public and the society can benefit too. This objective of interplay can be understood as an aspiration to support the endangered languages and the maintenance of lingual diversity, but also as a servant of “two masters”, the research and the society.
