The trend of the web is moving from portal-centered to user-centered, and RIA(rich internet application) is considered best solution for usability and functionality of the next generation web. But the lack of reference document or technical guide for RIA implementation is a big obstacle for extension of RIA environment to practical business engineer or user. In this paper, I will suggest the implementation conceptand reference site for user-centered environment based on RIA concept. The suggested concept support wire/wireless environment, and use the e-mail that is already used by many company or portal. The contents of this paper will be very helpful to the practical engineer or portal/company that want to use or implement about RIA environment.

This study aims to investigate current status and problems of bookmobile services in Korea, especially focusing on human resources, vehicles, and collections. To do this, a questionnaire that contained questions on basic information, human resources, vehicles, collections and information and communication technologies was developed on the basis of 8 standards and guidelines related to bookmobile services and 77 bookmobiles belonging to public libraries and Saemaul bookmobiles were surveyed. As a result, many parts of human resources, vehicles, and collections of bookmobiles in Korea were inadequate to standards and guidelines related to bookmobile services. At the end of this study, some suggestions are made for improving bookmobile services in Korea. First, the human resources, vehicles, and collections of bookmobiles need to be innovated. Second, national policies for bookmobile services need to be reinforced. Third, perspectives on bookmobile need to be modified from economic approach to information welfare approach.

A mashup is a web page or application that uses and combines information, contents or Open APIs available on the web to create a new service. The mashup developed by the need not combination of simple information can contribute to new added-values with practicality and convenience. Thus, in this paper, we want to develop a RIA-based dynamic mashup service for the users considering weather forecast and marine information importantly. We design and implement the system that it can register a number of information about a domain dynamically through registration process based on the map and present a mark of domain location on the map and the information including internal environment, external environment and weather of related to the domain within a webpage. Implemented service need not require a tedious process visiting other web sites every time to confirm the relevant information because we can see simultaneously related information with a map within a page.

The purpose of this study is to investigate the current status of services and programs of bookmobiles in Korea. To do this, a questionnaire containing 22 questions on basic information, scheduling and stops of bookmobiles, services and programs of bookmobiles, promotions and needs assessment and improvement requirements was developed on the basis of 7 foreign standards and guidelines related to bookmobile services. 74 questionnaires from bookmobiles belonging to public libraries and Saemaul bookmobiles were analysed. As a result, many parts of the results including operation days per week, stops per day, operation hours per stop, visiting cycle, circulation per day, circulation period and circulation volume and promotion conformed to foreign standards and guidelines but the others did not conformed to them. Also, there were more group differences in services and programs between bookmobiles belonging to public libraries and Saemaul bookmobiles than between bookmobiles in metropolitan cities and provinces in Korea.

The purpose of this research is to describe the characteristics of "One Book, One Community" reading promotion campaigns in which universities are involved in the U. S. A. Many universities and colleges in various communities participate in "One Book" campaigns in communities as leaders or partners, and promote reading for students on campus through either "One Book, One Campus" or "common reading programs." Universities can contribute a lot to "One Book" campaigns in communities by providing library collection, human resources, and facilities, and especially coordinating programs and events which require subject specialties. Also, they can promote the significance of reading literary classics. "Common reading programs" help freshmen easily adjust to campus life and build the sense of belonging to the "academic community" by reading the same book and talking about it with other members of universities.

Thin films of tin sulphide (SnS) have been formed by a novel 2-stage process where-in D.C. magnetron sputtering was used to deposit to thin films of tin (Sn) and the layers then sulphidised using 5% hydrogen sulphide ($H_2S$) gas in Argon. Although it was not found possible to deposit high quality thin films of tin directly onto glass substrates, excellent layers of tin were produced by using molybdenum (Mo) coated glass as the substrate material. The chemical and physical properties of the SnS layers formed were determined using scanning electron microscopy, energy dispersive x-ray analysis, x-ray diffraction studies and using reflectance versus wavelength measurements and these related to the conditions of synthesis. The data shows that it should be possible to produce conventional "substrate structure" devices based on the use of this technology.

The title compound (C13H17NO2S) is monoclinic, space group P21/a, with a = 13.756 (3), b = 9.310(4), c = 21.305(3) $\AA$, $\beta$ = 95.0。, Z = 8, V = 2718.11 $\AA$3, Dc = 1.23$g·{\cdot}cm-3$, (Mo k$\alpha$) = 0.71069$\AA$,$\mu$ = 2.18 cm-1, F(000) = 1071.86, T = 298, R = 0.085 for 2935 unique observed reflections with I >2.0$\sigma$(I). The structure was solved by direct methods. The C-H bond lengths and the methyl groups are fixed and refined as their ideal geometry by allowing to ride on the parent atoms. Both molecules A and B have almost same structures except for two terminal ethyl groups. The ethylene-like skeleton including the nitro group in one molecule is nearly perpendicular to the plane of the methylbenzene group and two ethyl groups form a cis-type structure which has the dfferent orientations between two molecules; in the molecule A, two terminal methyl groups being the opposite directional arrangement against the plane of its skeleton, while in the B, with the same directional structure from its plane. The molecules in the crystal are packed together by non-bonded van der Waals forces.

In the situation where various social problems are raised due to rapid aging, how to send a long period of old age is emerging as an important issue. As the life span is extended, education for the elderly is attracting attention as a means of sending meaningful and effective old age that is about over 20years longer than before. This study aims to analyse the current status and characteristics of elderly education as lifelong learning in Japan where has already entered a super-aged society. This is because it will be expected to find meaningful lessons and implication for the development of education for the elderly in Korea, which is becoming more important. In order to complete this purpose, the literature review was conducted based on the data and reports published by the Ministry of Health, Labour and Welfare and Ministry of Education, Culture, Sports, Science and Technology of Japan which are institutions related to education for the elderly. Through this, the practical and policy support for the elderly education development in Korea was suggested. In specific, diversification of lifelong learning contents and execution places, expansion of out-reach education, and fostering coordinators were provided.
