Korean Government has invested a lot of efforts on digital contents industry. It believes that the digital contents industry enables Korea to regain the reputation of the most powerful IT country. Among its various efforts to promote the digital contents industry, a Digital Contents Identifier System, called UCI(Universal Contents Identifier), has been developed and deployed. UCI has provided a critical infrastructure for digital contents production and distribution. Thanks to Korean Government's efforts, users (companies and individuals) have currently registered 3.8 million digital contents through 25 RA organizations. Although the number of registered contents has been increased rapidly, many organizations hesitate to adopt the UCI system due to the lack of visible and short-term returns from the UCI system. Thus, this research tries to explore factors which affect UCI user satisfaction. This research finds that user's awareness, information quality, and service quality are the critical influencing factors toward UCI user satisfaction. In addition, this research finds that the critical influencing factors in public organizations are different from the critical influencing factors in private organizations. These findings hopefully provide useful guidelines for disseminating the UCI system widely.

The present thesis aims to analyze in consideration of recent changes in teaching environment in the universities the commercial digital contents and e-learning courses provided by the libraries, and to propose the ways to encourage university library service needed under the current situation. A survey of professors and students upon the quality of commercial digital contents service provided by the libraries in I University was made to measure its influence upon e-learning courses. The quality of commercial digital contents service provided by libraries was measured through Digital Library Service Quality Index (which will be referred as DL-SQL Model from here), which is used as a model to examine the Digital Library Service, with partial adjustments of 4 levels (information system service, digital books service, customer service quality, and customer community service) and 7 components (search possibility, an exclusive organization and interface, accessibility, digital books, customer support service, personalized service, and customer community). Among the library services in regard to digital contents, "customer service" and "customer community service" were analyzed to have stronger influence upon e-learning teaching and studying than quality-based service for "information system" and "digital books". Consequently, it is concluded that customized information service provided by the library for the professors who teach e-learning courses and their students is more influential to supporting e-learning courses than quantity pushing service through purchasing commercial digital contents, upon which the direction of digital contents policy to provide library services for e-learning courses should be based.

To improve the quality control of frequently used oriental medicinal plants, the storage, cutting, processing and decokting methods of Rehmannia glutinosa Libosch. var. purpurea Makino(熟地黃) were examined. The contents of 5-hydroxymethyl-2- furaldehyde(5-HMF) of Rehmannia glutinosa Libosch. var. purpurea Makino were analysed by HPLC at various conditions as the standard component. Raw materials were classified into 3 groups with their specific gravity(天 地 人黃) and determined the ding weights and the contents of water, the solid component of Ji-Hwang(地黃) was the most. Rehmannia glutinosa Libosch. var purpurea Makino was steamed and dried nine times and analysed the content of 5-HMF on every time. In the case of Ji-Hwang, the standard component of the ninth sample was produced the most. But which of the tenth samples of Chun-Hwang and Yin-Hwang(天黃 人黃) were the most. The best decokting conditions which were determined by the yield of 5-HMF were as follows : non cutting, soaking time was 0 minutes, decokting time was 75 minutes after boiling. The contents of sugar on each of samples were determined. The contents of standard component increased by steaming number and the contents of sugar decreased.

This study was conducted to find pork quality to meet the needs of consumers. Thus, the meat quality and fatty acid composition of longissimus muscles from purebred pigs (Landrace, Yorkshire, and Duroc) and three-way crossbred LYD pigs were compared and evaluated. Chemical compositions of longissimus muscles were significant (p<0.05) different among pigs. Duroc contained significant (p<0.05) higher fat contents than other pigs, whereas significant (p<0.05) higher moisture contents were observed in Landrace, Yorkshire, and LYD pigs compared to those of Duroc pigs. The values of pH_{24 h} and pH_{14 d} were the highest in Landrace pigs. Myoglobin contents of LYD pigs were higher (p<0.05) than those of purebred pigs. Regarding meat color, Duroc and Yorkshire pigs had higher redness values than Landrace and LYD pigs, while Landrace pigs had the lowest (p<0.05) color values among all pigs. There was no significant difference in shear force or water holding capacity (WHC). Duroc pigs maintained the lowest drip loss during 14 d of cold storage. In sensory evaluation, the marbling scores of Duroc pigs were higher (p<0.05) than other pigs. Regarding fatty acid compositions, total USFA, poly-, n-3, and n-6 contents were the highest (p<0.05) in LYD pigs, while total SFA contents were the highest (p<0.05) in Duroc pigs. Based on these results, purebred pigs had superior overall meat quality to crossbred pigs.

The e-book technology is developing day by day with the expansion of e-ink technology. However, consumers' complaint over contents which are relatively deficient compared to paper book, the issue of compatibility of file between bookstores is not improved as yet. This means that present e-book market needs study in the viewpoint of consumer who intend to accept requirement of market instead of viewpoint of technical development. Thus, this study intends to measure the quality of three main attributes such as system, contents and service based on IS Success Model which compose e-book to identify the influence on readers' purchase intention. Result, System quality is to device purchase intention, and Contents quality is to e-book pruchase intention, it showed a significant damaging effect on.

One of the key factors for success in fostering web-service is the supply of user-generated contents(UGCs). Technological interactivity is an environmental factor which stimulates user-content interaction, and reflects the system's capability for supporting various interactions that are allowed by a medium. The present study uses a structural equation model to investigate the influence of three components of technological interactivity-user control, synchronicity, and responsiveness-on web-services' perceived content performance. The results show that web-services' user control and synchronicity exhibited a positive relationship with the perceived efficiency of content generation; further, perceived efficiency boosts perceptions of content quality, which means that the user control and synchronicity of a web-service also have an indirect effect on perceived content quality. Additionally, responsiveness has a positive effect on perceived content quality. These findings are important for marketers and operators seeking to make their web-service successful.

Increasing use of organically grown foods has renewed interest in the relationship between agricultural methods and food quality. The objective of this study was to evaluate the physicochemical characteristics and antioxidant activities of organic strawberries. For this study, strawberries were measured in terms of quality characteristics, including weight, length, diameter, hunter color, soluble solid contents (SSC), moisture contents, and pH, as well as antioxidant activities, including DPPH and ABTS radical scavenging activities and total phenol and flavonoid contents. Consequently, conventional strawberries showed higher weight, diameter, and L (lightness) and b (yellowness) values than organic strawberries (p<0.001). Length, moisture contents, pH, a (redness) value, and DPPH and ABTS radical scavenging activities were similar (p<0.05). However, organic strawberries showed higher SSC and total flavonoid and phenol contents than conventional strawberries (p<0.001). These results indicate that there were significant differences between organic and conventional agriculture techniques.

In rapidly changing educational technology and trends, services providing educational digital contents have been focused on offering new contents customized on the state-of-the-art technology and trends, rather than re-evaluating or eliminating the contents on service based on the changed topics and video quality. This study explores domestic cases about educational digital contents in order to draw implications on proper life-cycle models and effective re-evaluation periods for the quality assurance of the contents. To achieve this objective, representative services in primary-secondary, higher, and lifelong education sectors were selected, and experts in the services were participated in focused group interview. Based on the interview results, the re-evaluation process and life-cycle issues in the management of contents were analyzed according to the educational levels and the implications on the life-cycle models were drawn. This study contributes to establishing a basis for the systematic life-cycle policy of the services in order to make more sustainable management of the digital contents.
