The evolution of computing environments caused various dharges in our society. The change cj instruction media is one of these effects. WWW using network techndogy is regarded as a pov.powerful tool for rerrote instruction. The methods of utilizing network technologies in design instrudion and design process rould be diversified comparing with those of other general instruction. Computer graphics has been regarded as a very use!u design tool for its accuracy and rapidty. Network can help us to do creative work using cornplter graphics. The merits of this technology are sharing resources and rraking it easy to roIlaborate. Recent cxxnputer graphics instruction has some defects in oontents and methods. The oontents have a weak relationship with other industrial design subjects. From above, the purpose of this thesis is to use computer graphics and netv.urk technology for supporting basic design instruction. Virtual gallery using WWW can be a cyberspare v.tlere the evaluation of results and the exchange of information take plare. This tool makes it easier to oomrunicate and oollaborate with dassmates. A casestudy-Composition with basic objectswas exea.rted by individual for distributed asynchronous rmde. The results of this thesis are summarized for four factors. Rrst, it was easy to transform idea. Serond, student-oriented working was performed. Third, interaction among students was activated. Fourth, not only final results, but also midterm results was oonsidered for evaluation. These methods also have problems as rerent instruction methods, but it rould be used as a instruction tool to compensate for existing instruction methods.

Narcolepsy is characterized by sleep attack with excessive daytime sleepiness(EDS), cataplexy, sleep paralysis, and hypnagogic hallucination. Paradoxically, narcoleptics tend to complain of frequent arousals and shallow sleep during the night time despite their excessive sleepiness. However, nocturnal sleep fragmentation in narcoleptics is relatively ignored in treatment strategies, compared with sleep attack/EDS and cataplexy. In our paper, we attempted to investigate further on the poor nocturnal sleep in narcoleptics and to discuss possible treatment interventions. Out of consecutively seen patients at Seoul National University Sleep Disorders Clinic and Division of Sleep Studies, we recruited 57 patients, clinically assessed as having sleep attack and/or EDS. Nocturnal polysomnography and multiple sleep latency test(MSLT) were done in each of the subjects. We selected 19 subjects finally diagnosed as narcolepsy(mean age $26.0{\pm}18.3$ years, 16 men and 3 women) for this study, depending on the nocturnal polysomnographic and MSLT findings as well as clinical history and symptomatology. Any subject co-morbid with other hypersomnic sleep disorders such as sleep apnea or periodic limb movements during sleep was excluded. Sleep staging was done using Rechtschaffen and Kales criteria. Sleep parameters were calculated using PSDENT program(Stanford Sleep Clinic, version 1.2) and were compared with the age-matched normal values provided in the program. In narcoleptics, compared with the normal controls, total wake time was found to be significantly increased with significantly decreased sleep efficiency(p<.01, p<.05, respectively), despite no difference of sleep period time and total sleep time between the two groups. Stage 2 sleep%(p<.05), slow wave sleep%(p<.05), and REM sleep%(p<.01) were found to be significantly decreased in narcoleptics compared with normal controls, accompanied by the significant increase of stage 1 sleep%(p<.01). Age showed negative correlation with slow wave sleep%(p<.05). The findings in the present study indicate significant fragmentation of nocturnal sleep in narcoleptics. Reduction of REM sleep% and the total number of REM sleep periods suggests the disturbance of nocturnal REM sleep distribution in narcoleptics. No significant correlations between nocturnal polysomnographic and MSLT variables in narcoleptics suggest that nocturnal sleep disturbance in narcoleptics may be dealt with, in itself, in diagnosing and managing narcolepsy. With the objective demonstration of qualitative and quantitative characteristics of nocturnal and daytime sleep in narcoleptics, we suggest that more attention be paid to the nocturnal sleep fragmentation in narcoleptics and that appropriate treatment interventions such as active drug therapy and/or circadian rhythm-oriented sleep hygiene education be applied as needed.

While science museums, whose functions consist traditionally in collecting, preserving, researching, and displaying science-related objects, present scientific knowledge, figures, or tools in the historical context, science centers give more emphases on science education by exposing interactive exhibits to their visitors. However, neither objects-oriented exhibits nor hands-on technologies can provide museum visitors with the full insight into modem science in terms of its complicated relationships to politics, economy, culture, art, risk, and environment. This paper argues that for the 21st century we need to establish a new kind of science museum through the critical examination of its previous kinds - science museums and science centers. In the first part of this paper, the history of the first and second generations of science museums, including their recent trends in science centers, in the West will be elaborated. Secondly, the development of national science museums in Korea will be discussed specifically for the understanding of Korean science museums. The next part of this paper will seek for the possibilities of the third generation of science museums through three examples, which show interdisciplinary, contextual, and institutional approaches to change science museums or science centers. Fourthly, the social function of science museums as 'forum' will be discussed in relation to promoting public 'participation' of science as well as public 'understanding' of science. As a conclusion, some practical suggestions and conceptual guidelines will be proposed for the future Korean national science museum.

This study conducted a survey on the current status and satisfaction of libraries participating in the opening hours support project in order to continue it to meet the purpose of improving information access and life welfare. To this end, a questionnaire and interview survey were conducted for those in charge of opening hours for each library, and the results are as follows. First, the opening hours support project is a project that needs a strategy that fits the characteristics of the region and the environment. Therefore, it is necessary to consider operating independently rather than relying on national support in the future through the preparation of regional-oriented operation plans. Second, it is necessary to establish a flexible operating model for opening hours that both employees and users can understand. Third, it is necessary to prepare an organizational operation plan that requires both duties and responsibilities along with the rights equivalent to existing regular employees. Fourth, in order for national public libraries in Korea to develop and implement a consistent policy for specific policies and projects, it is necessary to unify the separate public library operating system in the future. Fifth, it is necessary to prepare education and guidelines for the continuity and stable operation of the project, and to activate services other than labor costs, such as support for improving the space for the user's pleasant use.

This study aims to identify priorities in book curation service that the teacher librarians perceive important through the AHP (Analytic Hierarchy Progress) method by comparing the jobs of teacher librarians with those of curators and selecting the contents and areas of book curation service provided by school libraries. For the purpose, this study categorized the book curation service areas by class and analyzed the priorities in the book curation service areas in the school libraries by applying the AHP method on the teacher librarians who are the personnel in school libraries. As a result, the priorities in the upper-tier class were turned out to be information services, improvement of expertise, information resources, management, and promotion & marketing in that order. The priorities in the lower-tier evaluation areas were shown in the order of survey & research, Q&A, self-development, exhibition, budget allocation, connecting with experts, trend analysis, reading education, human resources, planning, collaboration class, marketing services, book status, online promotion, offline promotion, and facilities & environment. Based on the results, this study suggested the following plans to provide effective book curation services in school libraries: grasping characteristics of school library users, setting classification criteria for book curation, and finding reader participation-oriented book curation service.

This paper is to consider the development process of conflict between Daegu and Gumi which has been arisen from Daegu city's plan of relocation of water intake plant. It first argues that water is a major common and public resource which is circulated through the social process as well as the natural one, and hence that conflicts within or between regions due to its allocation should be resolved or managed by construction of collaborative governance in which all stake-holders participate. In particular, it is pointed out that collaborative governance would be not only oriented to a normative goal, but also be mobilized as a strategic means. On the basis of this conceptual consideration, this paper explores the development process of conflict caused by Daegu city's plan of relocation of water intake plant, and analyze the starting conditions and deliberation process of the public-private committee which has been constituted through a consensus between Daegu and Gumi city government. It concludes that the current interruption of the committee has happened, because it has been mobilized politically as a strategic means for regional hegemony, not as a normative one to resolve the conflict.

Under the UN Security Council Resolution 1540/1810 in 2004 to restrict the proliferation of WMD (weapons of mass destruction) and their means of delivery, many countries have taken great efforts to, control the export of strategic items, thereby preventing the transfer of ABCM (atomic, biological, chemical weapons, missiles) and technologies and goods related to conventional weapons or dual-use items, Compliance Program (CP) in Korea or Internal Compliance Program(ICP) in Japan refers to a company's internal system or rules to comply with the export control laws and regulations, and is to prevent the unintentional illegal export of strategic items. This paper analyzes the Compliance Program (CP) of strategic export control system between Korea and Japan. Both countries have very similar legal frameworks under the guiding principles of multilateral export control regimes. However, there are some differences in actual procedures, classification service, supporting system, export license, sanctions for illegal exporters, etc. Korea should take more active and customer-oriented measures to promote the Compliance Program (CP) into Korean export companies for better awareness and positive attitude, practical information and education, smoothy government-firm communication, closer cooperation between Korea and Japan, etc.

According to the recent expansion of the network environment, the spread of smart devices is continuously increasing. With the spread of smart devices such as smart phones, smart pads and wearables, changes are taking place in smart technologies and IT convergence technologies. The development of smart technology is a key element of the 4th industrial technology. The Fourth Industrial Revolution expanded the new service-based industry by adding intelligence to residential, industrial and production environments using IT convergence and smart devices. Research on providing various services using smart technologies, such as smart home, smart factory, smart farm, and smart healthcare, is being conducted in variety. In particular, There is a sharp rise in smart homes due to the proliferation of IoT devices and the growth of sensor technology, control technology, applications, data management, and cloud services. Smart home services using smart technology provide residents with convenient, beneficial services and environments. Smart home service has complemented the existing home network service, but there still are flaws to be modified. In other words, the spread of smart devices, the development of service provider-oriented services, and the interlocking of services have limitations in providing services in consideration of user environment and user state. In order to solve this problem, this study proposes a smart home service system that considers the situation of the elderly.

Students' perception of science-related career strongly influences the formation of career motivation in science. Especially, the high level of science gifted students' positive perceptions plays an important role in allowing them to continue to study science. This study compared perceptions of science-related career between general and gifted middle school students using semantic network analysis. To ensure this end, we first structuralize semantic networks of science-related careers that students perceived. Then, we identified the characters of networks that two different student groups showed based on the structure matrix indices of semantic network analysis. The findings illustrated that the number of science-related careers shown in science gifted students' answer is more than in general students' answer. In addition, the science gifted students perceived more diverse science-related careers than general students. Second, scientific career such as natural scientists and professors were shown in the core of science gifted students' perception network whereas non-research oriented careers such as science teachers and doctors were shown in the core of general students' perception network. In this study, we identified the science gifted students' perceptions of science-related career was significantly different from the general students'. The findings of current study can be used for the science teachers to advise science gifted students on science-related careers.
