Previous test equipment was bulky, took a long time to check, and was somewhat less economical. Since most of the checks were about analog signals, we preferred to check them using reference equipments. In this paper, a digital circuit design based on AITS is used to implement signals that can not utilize commercial measurement resources, and also designed and manufactured equipment that can inspect SRU. These test equipments were tested and evaluated by development, operation, and field evaluation, and they were installed to the Korean Field Force. This contributed to the improvement of operability by shortening the inspection time from 83.2 minutes to 7.8 minutes on average In addition, it did not utilize the reference equipment, so it could play a big role in lowering the mass production cost.

I studied a distance education model for English learning on the Internet. Basic WWW files, that contain courseware, are constructed with HTML, and functions, which are required in learning, are implemented with Java. Students and educators can access the preferred unit composed of the appropriate text, voice and image data by using a WWW browser at any time. The education system supports the automatic generation facility of English problems to practice reading and writing by making good use of the courseware data or various English text resources located on the Internet. Our system has functions to manage and control the flow of distance learning and to offer interaction between students and the system in a distributed environment. Educators can manage students' learning and can immediately be aware of who is attending and who is quitting the lesson in virtual space. Also, students and educators in different places can communicate and discuss a topic through the server. I implemented these functions, which are required in a client/server environment of distance education, with the use of Java. The URL for this system is "http://park.taegu-e.ac.kr" in the name of GAIA.

NiO thin films are very attractive for use as an antiferromagnetic layer, p-type transparent conducting films, in electrochromic devices and functional sensor layer for chemical sensors, due to their excellent chemical stability, as well as optical, electrical and magnetic properties. In addition, (100)- and (111)-oriented NiO films can be used as buffer layers on which to deposit other oriented oxide films, such as c-axis-oriented perovskite-type ferromagnetic films and superconducting films, because of the similarity in symmetry of oxygen ion lattice and lattice constants between the NiO films and the oriented oxide films. Thus, controlling the crystallographic orientation and surface roughness of the NiO films for a buffer layer are very important.

The buffer and backfill are important components of the engineered barrier system in a high-level waste repository, which should be constructed in a hard rock formation at a depth of several hundred meters below the ground surface. The primary function of the buffer and backfill is to seal the underground excavation as a preferred flow path for radionuclide migration from the deposited high-level waste. This study investigates the hydraulic conductivity and swelling pressure of Kyungju Ca-bentonite, which is the candidate material for the buffer and backfill in the Korean reference high-level waste disposal system. The factors that influence the hydraulic conductivity and swelling pressure of the buffer and backfill are analyzed. The factors considered are the dry density, the temperature, the sand content, the salinity and the organic carbon content. The possibility of deterioration in the sealing performance of the buffer and backfill is also assessed.

This study was carried out in order to analyze consumers' attitudes of purchasing livestock products. Data were gathered through questionnaires from a total of 628 consumers throughout November to December, 2005. The results obtained were as follows: 1. The most favorite meat of consumers was pork(43.6%). However, there were highly significant differences among socio-economic status (SES) of consumers (p<0.001). 2. Among milk and meat products, including fermented foods, city milk was the most favorite of consumers (39.7%) and the next was ham & sausage (34.1 %). 3. A majority of consumers preferred domestic livestock products (85.0%) to imports (6.5%). 4. Some of the most important factors in purchasing animal products included price (38.0%), safety (37.0%) and brand (13.4%). Significant differences were found among age groups, education levels, and jobs. 5. A majority of consumers purchased their livestock products at big shopping malls (54.7%), super markets (11.0%), and so on.

Purpose: This study was to describe nurses' research activities, perceptions and performances of evidence-based practice and barriers to the use of research evidence in nursing practice in Korea. Method: A cross-sectional survey design was used. A questionnaire, except for Barriers Scale, was developed for the study. Data was collected from a convenient sample of 437 registered nurses working at research and education oriented university hospitals. Result: Nurses' research-related activities were relatively low compared to previous studies. Also perceptions and performances of evidence based nursing practice were low. Preferred informational resources for clinical decision making were identified as ward manuals/clinical guidelines, manager/senior nurses, and literature/research. The major barriers to research utilization were a lack of implication for practice along with inadequate facilitation to implement research evidence and difficulty understanding research written in English. Priorities of barriers factor were Administrator, Communication, Adopter, and Research. Conclusion: The findings provide directions for future training, education, and managerial policy to achieve successful evidence based nursing practice.

Mobile network infrastructure is being completed with the development of hardware and software for mobile devices. Network in mobile devices has evolved for telematics that is expanded much more than its existing concept. Telematics is compound word that is formed from the words "telecommunication" and "informatics". It means that telematics performs control and monitoring service with using mobile device resources. These services provide their services for users' requests through wired or wireless network from mobile devices and server that offers contents and network service collects management information of mobile devices. Map service is one of the preferred services for many telematics users. However, mobile map service has a limit between traffic and information sharing. Therefore it is very important to supply their information for both service provider and terminal user. In this paper, we design a new interactive sketch map using routes and information on the space to be applied effectively, and provide an extended document format that is defined to an extensible and dynamic clustering scheme to have portability map service for mobile device.

This study analyzed tourists' intention at Gangcheon Mountain, Sunchang-gun for local tourism. The contents of study included impression, characteristics, specialized resources, development direction, intention of visit and its form, destination prior and post visit, travelling expenses, and development form of tourism. The results were as following. Impression and characteristics showed that gochujang and fermentation industry established a strategic ground of local development. Intention of revisit of tourists was relatively high by 97.1%. Furthermore, tourists were mainly family units and they preferred family-based recreational type for the future local tourism development form. Therefore, a development strategy will be required that involves inexpensive accommodation, unique local food items, agricultural-specialty products and local tour packages. For invigoration of local tourism, recruitment of skilled managers for farm village experience will be necessary as well.

Central Asian Countries had been independent in 1991 from USSR. Since then it have been increasing foreign trade and investment amount with outside countries including China, Japan, EU and South Korea. Korean enterprises and entities have endeavored to secure plentiful natural resources, oil and gas energy and expand the market share to exporting the consuming and industrial competitive goods and services for those countries. In the case of disputes of commercial transactions and investment, arbitration is regarded as a dispute resolution system which has been preferred in international transactions and investments by the business world. Since the collapse of the USSR, Central Asian Countries have worked to modernize its arbitration law and procedure to conform with international standard rules. Arbitral legislation in Central Asian countries is based on the Model Law as adopted in 1985. However, CIS's legislation systems of arbitration are not satisfied with the international standard in national laws and practices. That is the reason to consider for the specific parliament about arbitration for the dispute resolutions in the commercial transaction and investment between Korean enterprises and CIS. In this article, it is discuss problems and its alternatives in the dispute resolution about the commercial transaction and investment into Central Asian countries including the tendency to the increasing the trade volumes of goods and investment between South Korea and CIS. According to this article, South Korea consider the long term strategy followed the preferred economic relative partnership for business success on commercial transaction and investment with the Central Asian Countries.

이 글은 근로자가 직장을 선택하는 과정에서 원하는 직장을 선택하는지 여부가 근로자와 일자리의 일치도를 나타내는 데 한 지표로 활용될 수 있다는 점에 착안하여, 그러한 입직 과정에서의 희망직장 선택 여부가 근로자의 임금에 어떤 영향을 미치는지 살펴보고자 한다. 특히 이 글에서는 패널 자료를 활용하여 근로자의 비관측된 이질성이 임금에 미치는 영향을 통제할 수 있는 모형을 제시하고, 그를 한국노동패널 조사의 3개년 조사 결과에 적용하여 희망직장의 선택 여부에 따른 임금격차를 계산하였다. 그 결과 우리는 희망직장의 선택 여부에 따라 약 50% 이상의 임금격차가 발생함을 발견할 수 있었으며, 이러한 임금격차가 전통적인 임금격차의 설명틀로 설명될 수 없다는 점에서 일자리에서의 생산성 격차가 그 원인일 가능성을 제기하였다. 이 경우 이러한 가능성에 대한 분석이 이뤄지지 않았다는 점은 이 글의 한계로 지적될 수 있으며, 추후 연구를 통해 규명되어야 할 것으로 보인다. 그럼에도 불구하고 이 글의 분석 결과는 직업알선 활동의 개선을 통해 경제 효율성이 증대될 수 있으리라는 점을 시사하는 것으로 보인다.
