They say the 21 Century is the culture-centered age. As the income is increased. the concern about human culture will cause the elevation of life quality and the growth of culture needs. For that reason library service to meet their user's need for culture will be needed. The purpose of this study is to improve the university library service to suggest the solution for successful developmental strategy on cultural program of university library with the positive approach of analysis and evaluation. For specific instance, the cultural services of S women's university library was analyzed and evaluated. The point of the evaluation are five aspects: 1) the recognition of the users for the overall cultural services 2) the satisfaction index for the contents(topics) of the cultural services 3) the satisfaction index for the way of managing 4) the participation index of users. As the result of the analysis, the specific solution for the strategy of university library's cultural services for the future would be suggested.

The purpose of this study is to help out the settlement of the Green Map in Korea, and to suggest how to map, and help community people and environmental planner systematically take care of their own towns. This study is also to introduce the green mapping and its usefulness, based on the Green Map Movement, which originated from Net York City and has been expanding through the World. Environmental elements shown on the Green map vary between countries and for the Seocho-Gu Green Map, we have decided to indicate the places that we are proud of, and dishonored of. Especially, this paper is focused on finding the hidden environmental resources in our daily lives. Seocho-Gu, one of 25 self-governmental resources. Since the citizens and government officials are open-minded in their environments, it is a suitable area to start the first Green Map in Korea. As a method of locating the environmental resources, the "Foot Sensing Method" by which residents directly research, is the main difference from typical maps by the "Remote Sensing" which focused on the variety participation of the residents such as questionnaires, investigation with youth volunteers, users interviews which may be more meaningful than the Green Map itself. The purpose of application plan is to preserve the environmental resources through the smooth feedback with the residents. Thus, it must be acted as a opening window linking them with the local circumstances. In line with this, this study proposed the trial-version Web Green Map and Green tour plan. Recently, a need for an environmental map has been reflected in the environmental policies of Seoul Metropolitan City, and it is in place now. If environmental experts of different disciplines use the Green Map for landscape architecture, design, and city planning, it will help them make a better understanding of the needs of the community and to practice the user-centered design. Eventually, the Seocho-Gu Green Map will help its residents, tourists, government, and environmental planners continue establishing the healthy city environments. It is expected that the green map will be employed as a useful method for establishing healthy city and town through right way of use and contents.of use and contents.

Today, the world is evolving into a huge community that can communicate with real-time information sharing and communication based on the rapid advancement of scientific technology and information. Behind this information, the adverse effects of information assets, such as hacking, viruses, information assets, and unauthorized disclosure of information assets, are continually increasing as a serious social problem. Each time an infringement of the invasion and personal information leaks occur, many regulatory policies have been announced, including stricter regulations for protecting the privacy of the government and establishing comprehensive countermeasures. Also, companies are making various efforts to increase awareness of the importance of information security. Nevertheless, information security accidents like the leaks of industrial secrets are continuously occurring and the frequency is not lessening. In this thesis, I proposed a customized security policy methodology that supports users with various business circumstances and service and also enables them to respond to the security threats more confidently and effectively through not a monotonous and technical but user-centered security policy.

Usability has become an important consideration for product development, and as a result, there is a growing need for systems and tools that can support usability test projects. However, few studies so far have developed such systems and tools. During a usability test project, many participants take up different roles, such as project managers, usability testers, and subjects. We implement a web-based usability test system with which a project manager can manage and control all participants and documents throughout the entire usability test process, from the design of a usability test project to the analysis of the test results. A usability test generates many documents, such as subject agreement forms and before/after questionnaires. Since many different subjects can participate in a usability test, consistency during testing with different participants and efficient document management are the keys to success for a usability test. Since all users that participate in usability test projects can access web-based usability test systems through a web browser, regardless of the place where they are, the reliability of the testing results can improve since the tests are conducted in the locations where the target products are meant to be used. In particular, our system is useful for disabled individuals who cannot move.

An image recognition for surrounding conditions is very important in image transmission. In recently rears, as the information infrastructure is more general, the user-centered demands in which they want to identify by object's states image using wire or wireless environment have increased. However, existing mobile solution could be hard to expect high quality mage, because limitation of software processing according as network based on mobile terminal which has low band width supports software codec. To solve this weak point, this paper describes on hardware codec design based on MPEG-4 which is international video compression standard. Implemented system contains the embedded CPU for optimized design and it works high quality service as transmission speed and resolution in mobile circumstance.

In this study, we evaluated the uncertainty in the process of selecting GCM and downscaling method for assessing the impact of climate change, and influence of user-centered climate change information on reproducibility of Chungju Dam inflow was analyzed. First, we selected the top 16 GCMs through the evaluation of spatio-temporal reproducibility of 29 raw GCMs using 30-year average of 10-day precipitation without any bias-correction. The climate extreme indices including annual total precipitation and annual maximum 1-day precipitation were selected as the relevant indices to the dam inflow. The Simple Quantile Mapping (SQM) downscaling method was selected through the evaluation of reproducibility of selected indices and spatial correlation among weather stations. SWAT simulation results for the past 30 years period by considering limitations in weather input showed the satisfactory results with monthly model efficiency of 0.92. The error in average dam inflow according to selection of GCMs and downscaling method showed the bests result when 16 GCMs selected raw GCM analysi were used. It was found that selection of downscaling method rather than selection of GCM is more is important in overall uncertainties. The average inflow for the future period increased in all RCP scenarios as time goes on from near-future to far-future periods. Also, it was predicted that the inflow volume will be higher in the RCP 8.5 scenario than in the RCP 4.5 scenario in all future periods. Maximum daily inflow, which is important for flood control, showed a high changing rate more than twice as much as the average inflow amount. It is also important to understand the seasonal fluctuation of the inflow for the dam management purpose. Both average inflow and maximum inflow showed a tendency to increase mainly in July and August during near-future period while average and maximum inflows increased through the whole period of months in both mid-future and far-future periods.

The study aims to analyse Korean Long-Term Care Insurance system in terms of caring justice on the premise that elder care should be included in discussions and policies of care. Caring justice means an ideal of equal sharing duties and rights of care by all citizens. Four dimensions of caring justice(decommodification, defamilialization, degenderization and elderly participation and power) were established for the analysis. The results of the analysis were presented that Korean Long-Term Care Insurance system was maintained by commodificated and gendered care services attempting defamilialization with the exclusion of elderly beneficiaries, which represented typical caring injustice. Policy suggestions were made to realize caring justice: improving the status of caring labour by achieving proper service price and public employment, reorganization of life cycle based caring system integrating children, disabled adults and elders, and developing user-centered long-term care system to guarantee participation and choice of people in caring relationships.
