The expansion of media art has not only developed the digital technology but also given lots of environmental evolution to improve various fields of design as the main topic of the 21st century. The purpose of this study is aimed at proposing the new design that integrates fashion accessaries with media art technology. This will be done by understanding the social environment in digital ages and studying technology of design based on a variety of literature about changes in our society, neo value, vision, culture and art with fundamental notion of media art. First stage for this study, put an idea into just fashion accessary design because it is not sufficient to incoporate fashion and media art technology. The presented OLED(Organic Light Emitting Diodes) in this study is a kind of display to be in a limelight in the next generation and can be applied to various field of design. media art simultaneously moved into the scope of artistic debates. As a result, we can found that the use of audiovisual introduced numerous new aspects to the conceptual and aesthetic engagement with questions of conception. Today, the presented forms of art and inter-action from the closed -circuit work to interactive media art installations to open process-exist as parallel possibilities.

The residential apartments have become a choice of a popular housing space since the first establishment of Mapo apartment in 1962. Therefore, the residential market experienced a bloom where residential apartments were sold as they were built simultaneously. However, this phenomenon was turned around and unsold lots appeared after the period of IMF and as the construction companies put out more various apartments by differing the characters and the strategies in building apartments. As a result, the leadership of residential market moved from the suppliers to consumers, in consequence, the wants of the consumers became more demanding. The consumer can freely control the number of rooms with a variable wall system or a bigger sized apartment with two entrances to the living room as well as having a bathroom with a master bedroom in a small-sized apartment. Many conceptual trials like this were taken to improve the residential environment and to give a change to the unit plan of the public housing. From these changes, one can observe a general trend that is taking place in current residential housing. Consequently, this study is on the type classification of unit plans in public housing built after 1999 and dwelled from 2001. The objectives of this study are to confirm the characteristics of the unit plans applied in recent public housing and provide basic materials that can be incorporated to residential space plan from now and hereafter.

With the rapid and broad changes of information ecology, the environment within which cataloging principles and standards operate has changed dramatically. As a result, IFLA study groups developed Functional Requirements for Bibliographic Records(FRBR) model which is a conceptual model for bibliographic universe. This study intends to make a comprehensive inquiry about historical meanings and functional features of FRBR model. To the end, a comprehensive literature survey and analysis was conducted to introduce how hot and serious the discussion on this model in library cataloging. In conclusion, this study made several suggestions on the role of academic and library world (or applications of this model in Korea Library circumstance.

This study is to analyse the hydrological behavior of agricultural reservoir using CAT (Catchment hydrologic cycle Assessment Tool). The CAT is a water cycle analysis model in order to quantitatively assess the characteristics of the short/long-term changes in watershed. It supports the effective design of water cycle improvement facilities by supplementing the strengths and weaknesses of existing conceptual parameter-based lumped hydrologic models and physical parameter-based distributed hydrologic models. The CAT especially supports the analysis of runoff processes in paddy fields and reservoirs. To evaluate the impact of agricultural reservoir operation and irrigation water supply on long-term rainfall-runoff process, the CAT was applied to Idong experimental catchment, operated for research on the rural catchment characteristics and accumulated long term data by hydrological observation equipments since 2000. From the results of the main control points, Idong, Yongdeok and Misan reservoirs, the daily water levels of those points are consistent well with observed water levels, and the Nash-Sutcliffe model efficiencies were 0.32~0.89 (2001~2007) and correlation coefficients were 0.73~0.98.

The purpose of this article is to identify the problems that Korean library and information policies (LIP) are facing with and to suggest its future direction for advancement. To the end, discussions include both progress and problems related to legal provision, government organization, administrative staff, professionals, finance, and master plans. Based on a thorough literature survey, this article begins from an analysis on the conceptual definitions of 'library and information policies,' explains the problems and limitations of Korean LIPs before 2006(the year when new 'library act' was established), and introduces major changes in Korean LIPs after 2006. Finally suggested are both strategies and methods to resolve the problems and limitations that Korean LIPs are facing with.

In this paper, we newly propose a performance enhanced CSMA/CD MAC(Medium Access Control) protocol for the Ethernet which changes its operation mode dynamically according to the network status, not fixed it as one of p-persistent mode and non-persistent mode. Dynamic mode change occurs independently on each node, and uses the consecutive success count and the fail count of the frame transmission. The simulation result shows that the dynamic mode change maintains the enhanced network utilization and transmission delay characteristics. Also we show the implementation simplicity of our MAC protocol through its conceptual design using the Ethernet commercial chip as it stands.

From water management point of view, the industrialization that we have achieved in the last decades brought out two major changes: water shortage and water quality deterioration. They are getting the big obstacles we must overcome to continuously pursue industrialization for further development in the next century. Many plans using dams and advanced treatment methods have been developed for control of quantity and quality, respectively. In this paper, an alternative is conceptually reviewed which is much different from the plans in regard that the alternative looks at system itself. It is based on an interceptor system coupling with a concept of zero-discharge. This system allows no discharge of wastewaters from point-sources to waterbodies which are very sensitive in terms of water quality. In addition reuse of treated effluents is emphasized to a maximum extent. The application of the system to the Nak-Dong river basin indicated that an interceptor system will need from the middle reaches of the basin where industrialization gets heavier. Since wastewaters are not directly discharged to the river, water quality of the down stream will improve. Treated effluents will be able to be reused at a number of industrial complex which currently get water from the Nak-Dong river. This reuse will help alleviate water shortage. The biggest problem anticipated is cost for building and operating such system. A cost-sharing plan among the beneficiaries is considered. Further research is suggested focusing on detailed engineering and technical matters for potential implementation.

The connection between the continuousness of Rabi oscillation and the discontinuity of quantum jumps has long remained one of the conceptual difficulties since the discovery of the quantum physical paradigm. In this study, however, we demonstrate that the behavior of the atom-field composite system gradually changes from the continuous Rabi interaction to the discontinuous quantum jumps as the atom-field coupling strength is reduced. The reduction occurs through enlarging the quantization volume of the mode so that the mode approaches one of the infinitely many modes of the thermal background.

Current cost income is composed of current operating profit and holding gains. There is two viewpoints about the nature of current cost changes: earnings and capital adjustments. The former is based on the financial capital maintenance concept, while the latter is based on the physical capital maintenance concept. Proponents of current cost accounting are convinced that it provides more useful information than conventional accounting. Advocates of financial capital believe that current cost information is needed for management to evaluate their past decisions, and thereby be able to improve their decision-making ability. Defenders of historical cost point out that current cost accounting violates the traditional revenue recognition principle by recognising increases in the value of assets before sales.

The purpose of this study was to examine the effects of animation-based instruction on elementary students' level of understanding and interest on a plant's structure and function, using "Magic School Bus(Joanna Cole, Bruce Degen, 1986)". The understanding and interest measurements were administered to 99 fifth grade students at a elementary school located in Seoul. The study examined the changes in understanding and interest through pre-test and post-test of the two groups. Intensive interviews were conducted to find factors that enhance understanding and interest. Three key findings were revealed from the results. First, the animation-based instruction enhanced the level of understanding in the experimental group compared to the control group. Second, animation-based instruction made high-achieving students enhance their interest in topic component and attitude component. And, animation-based instruction did not led low-achieving students to increase their interest in the topic component and attitude component. We suggest that animation-based instruction positively influences students' understanding, but its effects on students' interest are dependent on their conceptual understanding of the topic.
