Since a 'Well-being' theme had become an issue in 90's, everyone now care about their health more than ever. Besides, IT has been developed so tremendously that we have various ways to collect up-to-dated information through the internet. In this thesis paper, I propose a web site called 'Calory&Diet' that provides customized information on diet. With its user friendly menu and feedback information, the proposed web site can be a good advisor for people who want to be healthy.

DB Integration website(tentatively named Food Processing Aptitude Information Center, FPAIC) has been designed through a "high-value products development project(2013)". Basically, the project aims to secure connections between food raw materials and processing industry, a variety of information sources, and users's convenience. It also aims to build the industry-university-based mutual growth in the food industry through sharing of processing suitability and material research on food raw materials. FPAIC consists of raw material story, information of sample characteristics, food processing study, preceding research data, food industry trends, and understanding of food processing. The major database of research on Food Processing is provided on information of sample characteristics, and food processing study. Currently the web site has 36 raw material stories, 380 information on sample characteristics and food processing studies, 1,600 preceding research data about 31 food raw materials. The web site also provides information on 70 useful web sites, as well as 77 food industry trends, 27 basic information about food processing.

블로그는 다양한 주제 분야에 대한 내용을 자유롭게 표현할 수 있는 일종의 개인 웹사이트로, 많은 양과 다양성으로 매우 중요한 정보원이 될 수 있다. 블로그는 생산속도가 매우 빠르므로 보다 고품질의 블로그를 선별하는 것이 중요하다. 본 논문에서는 블로그의 본문을 담고 있는 포스트를 대상으로 기계학습 기법을 이용하여 문서의 품질을 자동으로 평가하고자 하였다. 학습을 위한 자질로는 모든 블로그에 공통적으로 적용할 수 있도록 형태소 분석에서 추출한 동사, 부사, 형용사의 내용어만을 선택하였다. 성능 비교를 위해 수작업으로 약 4,600개의 정답 집합을 구축하고, 적합한 기계학습 기법을 찾기 위해 다양한 학습 기법을 사용하여 비교 실험하였다. 실험 결과 Bagging 기법의 성능이 79% F-measure로 가장 좋음을 보여주었다. 한정된 자질을 사용했을 때와 정답 집합의 문서 수 비율이 불균등할 경우 단순함, 유연성, 효율성의 특징을 지닌 Bagging 기법이 적합할 것으로 보인다.

Article 22(1) of the Library Act, which was completely revised in December 2006, stipulated that regional representative libraries are statutory organizations, and Article 25(1) of the Library Act, which was revised again in late 2021, renamed them as metropolitan representative libraries and expanded their duties. The reason why cities and provinces are required to specify or establish and operate metropolitan representative libraries is that in addition to their role as public libraries for public information use, cultural activities, and lifelong learning as stipulated in Article 23 of the Act, they are also responsible for the legal works of metropolitan representative libraries as stipulated in Article 26, and lead the development of libraries and knowledge culture by serving as policy libraries, comprehensive knowledge information centers, support and cooperation centers, research centers, and joint preservation libraries for all public libraries in the city or province. Therefore, it is necessary to analyze and diagnose whether the metropolitan representative library has been faithfully fulfilling its legal works for the past 15 years(2009-2023), and whether it is properly providing the results of its statutory planning and implementation on its website to meet the digital and mobile era. Therefore, this study investigated and analyzed the performance of the metropolitan representative library for the last two years based on the current statutory tasks and evaluated the extent to which it provides them through its website, and suggested complementary measures to strengthen its web services. As a result, it was analyzed that the web services for legal works that the metropolitan representative library should perform are quite insufficient and inadequate, so it suggested complementary measures such as building a website for legal works on the homepage, enhancing accessibility and visibility through providing an independent website, providing various policy information and web services (portal search, inter-library loan, one-to-one consultation, joint DB construction, data transfer and preservation, etc.), and ensuring digital accessibility of knowledge information for the vulnerable.

With the expansion of EC and the development of culture industry, Web-site shopping of cultural products have become recognized as one of the major purchasing channels for customers, as well as one of the competitive distribution channels for film distributors or theater group. The research is to investigate the impact of information quality and user interface quality on information service satisfaction and online purchasing intention of cultural products. The results of this study are as follows: 1) Both information quality and interface quality have meaningful influence on information service satisfaction and purchase intention. 2) Information service satisfaction gives significant impact on online purchasing intention irrespective of the level of customer involvement. 3) Information quality has a meaningful influence on online purchasing intention in case of high level of customer involvement, while interface quality gives strong impact on online purchasing intention in case of low level of consumer involvement. In conclusion, there is a need to consider the level of customer involvement for building a successful marketing strategy of online purchase sites of cultural products.

As the Internet and mobile services increase, the use of wired/wireless web contents services increase and the demand for various contents explosively grows. To survive in competitive market, and to minimize the errors and warnings for web accessibility and standardization, and then to maximize the web usability, the periodical evaluation for web site should be performed with the events of web marketing and campaign. Through the web evaluation, the errors for technical programming language and contents offering can be found and diagnosed. In this paper, the quantitative and qualitative evaluation method for web site providing web contents are presented, and the analytic results for the 138 home pages in domestic are evaluated to validate the quantitative methodology. The accessibility, standardization, and usability factor are adopted for the evaluation in which accessibility is evaluated for perceivable, operable, understandable, and robust discipline with K-WAH(Korea-Web Accessibility Helper) tool, the standardization are measured for the number of errors and warnings in technical language with the W3C validator, and finally the usability factor is analyzed for the number of visits, average visit duration, and bounce rate with Google Analytics. In addition to, the quantitative analysis is also performed with the consideration of cost for construction and operation of web site. From the results, in the case of total score of 100 in conversion with relative weight, the average and standard deviation are evaluated to be 55 and 14, respectively. The correlation analysis indicates that the coefficient is estimated as 0.058, and then correlation between the quantitative results and cost is evaluated to be a little positive.

The research aims to recommend strategies to promote PR activities of 'the Memory of the World(MoW)' on the websites. To achieve the goal, the researchers analyzed the current conditions of online PRs of the MoW in S. Korea by developing the standards/elements for analysis. The research examined the two main concepts of MoW and extracted the three core standards/elements for evaluating current online PRs of MoW through reviewing earlier studies: contents of PRs, ways of PRs, and features of media. The research examined PR activities on the 21 websites of 11 institutions which manage MoW in South Korea. The research found the significant features of the online PRs and suggested detailed strategies for improving the online PRs of MoW: first, it is required to emphasize the values of both preservation and utilization of MoW equally. Second, it is necessary to promote the PRs of MoW by using the way of 'user segmentation'. Third, it needs to develop the unit systems and/or services to integrate with related documentary heritages so that users can access documentary heritages effectively and efficiently. Finally, it is required to develop the guidelines or/and manuals to conduct and promote the PRs of the MoW by providing specific directions and methods of publicities.
