The success of social networking sites (SNSs) may depend on many factors. Continuance use of SNSs is one of these. Especially, in the Web environment where users can leave one service with a single mouse click, maintaining existing members cost much time and efforts. Without continuance use of SNSs, SNS-based service would not create any value. This study focused on identifying factors influencing users' continuance intention in SNSs. Based on relevant literature review, six influencing factors were initially identified. They were reputation, relational capital, knowledge quality, compatibility, personalization, and satisfaction. Web-based questionnaire survey was conducted and a total of 325 usable responses were collected. Reliability test and two rounds of exploratory factor analyses resulted in identifying five factors. The relationship between the factors and the continuance intention was tested by using multiple regression analyses. The analyses revealed that satisfaction was the most significant factor. Knowledge quality and relational capital also had significant effects while reputation and personalization did not have significant effect on continuance intention. Instead, reputation and personalization showed significance in influencing satisfaction.

In the construction industry, IT based information system has been diversely applied to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced to gather information in construction site, the effect of the IT device is limited, because of bringing about additional works of engineer. In this paper, we proposed a defect management system which is based on handwritten document digitalization framework for introducing applicability of new IT device, digital pen. By the proposed system, we can effectively gather and input defect information to defect management system by using digital pen and paper like conventional way. Applying the data gathering device, digital pen to defect management, it is able to increase productivity by improving work process, building up and utilizing defect information database of good quality.

This study attempted to investigate use of information for school foodservice management and perception of informations offered on Office of Education homepages according to Daegu and Gyeongbuk nutrition teachers and dietitians. The most frequently used web site information source and information type were 'charged foodservice information sites'(63.5%) and 'information on nutrition or menus'(63.5%), respectively. Subjects belonging to schools that served more meals per day tended to use informations more frequently. Information on 'management of the foodservice production process' showed a low satisfaction level as compared to importance in all groups, and information on 'nutrition education' showed a similar tendency for subjects belonging to schools that served 1 meals per day. Overall, efforts for development and dissemination of information are required to improve the quality and efficiency of school foodservice.

This paper introduces a 'Hanmal' Korean language diphone database for speech synthesis, which has been publicly available since 1999 in the MBROLA web site and never been properly published in a journal. The diphone database is compatible with the MBROLA programme of high-quality multilingual speech synthesis systems. The usefulness of the diphone database is introduced in the paper. The paper also describes the phonetic and phonological structure of the database, showing the process of creating a text corpus. A machine-readable Korean SAMPA convention for the control data input to the MBROLA application is also suggested. Diphone concatenation and prosody manipulation are performed using the MBR-PSOLA algorithm. A set of segment duration models can be applied to the diphone synthesis of Korean.

기능점수 방법은 소프트웨어 비용산정을 위한 규모산정에서 많이 이용되고 있다. 그러나 게임콘텐츠에서는 이를 이용하지 못하고 있다. ISO/IEC FDIS 19761(final draft)[8]에서는 게임콘텐츠에서 FP를 이용하지 말 것을 권고하고 있다. 이에 게임요소점수방식을 고안하였으나, 이 방식에서 쓰이는 게임요소의 가중치가 분명치 않은 부분이 있어 여기서 이 부분을 다루어 그 내용을 명확히 하였다. 게임요소에 대한 정의를 하여보고, 이중 그 의미가 불명확한 미션에 대하여 다소 세부적으로 다루었으며, 이들 게임요소의 가중치를 산정할 난이도에 대하여 검토한다. 난이도는 규모산정의 중요요소이므로 게임요소에 대한 명확한 난이도의 구분이 필요하다.

We studied how to achieve successful implementation of massive research and development projects requiring collaboration among industries, universities and government-supported research institute. We have set up an engineering process innovation model to be deemed most adequately for all practical purposes, relying on the theoretical studies on the merits and analysis of the effect of the information system based on Milestone Management, Work Breakdown Structures and Web, which is known to be effective for research project (schedule) management and the objective management, and implemented a real-world web-based project objective management system. After a review of various R & D Project Schedule Management methods, we found that this information system was very compatible with project objective management. This project objective management information system carries out research and development projects effectively and efficiently, getting together in cyber-space and sharing information, and has been equipped with an Early Warning Subsystem to allow for pre-analysis and timely response to potential problems arising from the course of the project. The system also contains an Executive Information System that in real time, automatically provides the management information required by managers with the rate of project progress (achievement, fulfillment and delay). Lastly, actual progress can be cross-checked through both on-line objective management on the web-based information system and design review meeting held on site, to improve the efficiency and validity of the information system. Moreover, overall effect was analyzed through questionnaires on how well the system and generated information meet requirements and on the ultimate impact of the system upon objective management and communication. The questionnaire on the system effect revealed that the information system was useful to objective management and communication, and that the quality of the system was more than acceptable as well.

In the past, strong social bands, which had spontaneous communities, existed in Korean traditional society. However, while it's developing through industrialization; monolithic apartment houses were introduced which causes less interaction between neighbors. With the growing attention to the higher living quality, various schemes to revitalize the community spirits have been groped, including to improve in hardhearted neighborhood relationships and to cope with the dreariness in the city. With the development of the internet and the spread of 'digital home', the communities in cyber space have been especially revitalized since the information-oriented society. In a move to strengthen the communities in apartment complexes, this study tries to find the revitalization scheme for virtual communities in apartment complexes by analyzing the contents of its web sites and understanding the world of virtual community. These are compared and analyzed. The related virtual communities ("cafe" or "blogs") are also analyzed. The results are as follows. 1) There are some differences among the contents provided by apartment virtual community developing companies, still, it could be categorized into four types; "apartment complex introduction and management information" "community revitalization" "living guide" "individual services" 2) The contents provided by self-organized communities of residents neither require additional charge nor special membership for information while the formation is not systematized. 3) In the comparison of apartment virtual community developing companies with residents self-organized communities, "apartment complex introduction and management information" on freeboard, notice, request and Q&A, and "community revitalization" on communication board are both provided throughout the web sites. 4) The contents provided by apartment virtual community developing companies makes the information available in a wide range with managers, on the other hand, self-organized communities emphasize on showing attachment and concern of residents and requiring communications between neighborhoods.

The study aims at assessing information on cultural festivals furnished through the internet homepage of a provincial government. The study examines 29 tourist festivals of ˝Cultural Festivals of Korea 2001˝, designated by the Ministry of Culture and Tournism. Based on the inquiring table, framed through the previous study, each festival´s information was surveyed and analyzed, by visiting the homepages of provincial governments. The results of the study show that 1) ˝The information of festival˝ is low in quality. Particularly, ˝the contents of festival˝ needs to be improved and expanded and ˝the festival periods˝ should be brought up to date. These are the important factors in making a decision to participate in the festival and the chief attraction of a homepage, well-planned and detailed information can influence more tourists who are interested in visiting a festival. 2) Seventeen festivals support ˝foreign language˝. But ˝festival information˝ is weak as it provides only an outline of festival and doesn´t even contain the date and contents of festival. Valuable information, like transportations, accommodations and restaurants when tourists visit a tourist spot, and detailed festival contents should be provided. 3) ˝Search˝ and ˝Q and A˝ are function which provide specifics for users. In addition to the homepage of a local government, these functions on the web page of cultural festivals or on an exclusive web page of tourism is required. 4) The homepage of festivals should offer ˝the information of participation˝. The convenience of information searchers should be considered by providing them information such as local prices, transportations, accommodations and restaurants which are necessary to participate in festival.
