This study is aimed at the development of comprehensive environmental management system, which can be operated on the basis of world wide web, as a topic of G7 project. Even though there should be lots of works remaining to achieve this goal, preliminary products can be summarized as follows : 1) integrated environmental information management system, 2) web based control engine, 3) surface water environment management system, 4) subsurface water environment management system, 5) sewer and waterworks management system. The core methodology of the engine is the generalized multidimensional finite element matrices to depict the terms in the analysis of various partial differential equations. Spatial information management system (ArcView) and Visual Basic were extensively employed to construct GUI oriented web based engine. The developed systems were composed of very intense computer codes due to the necessity of combinatory management of environmental problems. The web based engine could be served as a decision tool for the integrated management of environmental projects in Korea.

It is very common to produce fairytales, folktales, or fables into animations. If they often transform existing works into animations, we may have to examine how they change the original to communicate with the audience and also how they change the original's subject matter or theme to create meaning. The purpose of this study is to consider how the original's meaning and value were changed as Hans Christian Andersen's fairy tale, "The Snow Queen", was converted into an animation, , and also how it influenced the work itself. To attain the goal, this author is going to comparatively analyze the two works' narratives, actants, and semiotic squares by using A.J. Greimas' semiology. According to the findings, although "The Snow Queen" expresses the desire to go back to happy days in the past, it is not a simple return to the past but a stepwise process to become mature mentally as well as religiously. Meanwhile, intends to generate past-oriented meaning expressing the desire to return what is abnormal in the present to what was normal in the past and resolve the individual and religious aspects of "The Snow Queen" in a social and popular way.

The goal of educating consumers regarding food safety is to increase consumer competency in food safety. In order to recognize consumer problems and to develop consumer competency in rapidly changing consumer environment, it is necessary to cultivate consumer knowledge, attitude, and ability on food safety required in performing the consumer role effectively. Within this context, it is necessary to develop consumer-oriented education programs which aim to change consumer values and behaviors with regard to food safety. Based on information obtained from focus group interviews, the need for educational programs for food safety, which are related to the whole process of food consumption, have been raised. The process of food consumption is divided into buying, cooking/eating, and after eating, based on the process of consumer decision making and consumer behavior. Scenarios for consumer education on food safety were developed depending on the process of food consumption. This study developed a pilot consumer education program which included the whole process of food consumption. The program of this study was designed to induce consumers to change their behavior through establishing values on food safety and may contribute to lay the foundation for the realization of food safety culture. The results will be utilized to provide future directions for consumer education programs and efficient educational materials on food safety. Finally, it is hoped that empirical evaluation and analysis on the effects of consumer education programs will be investigated in future studies.

Data visualization has become a useful tool to effectively communicate information and is widely used not only by experts but also at a general level. However, it is dangerous that it is as efficient as it is to transmit false information. All data visualizations have hidden intent with powerful messages by editor. Building a system that grasps these intentions helps to understand the thoughts of groups and individuals. Most of the existing research focuses on effective data visualization methods and methods of expression. The more various visualization methods, the more likely the data will be distorted. In this paper, we present an analysis of deceptive data visualization in a goal-oriented environment. Based on the vulnerability of human cognitive processing, we classify the attack types and identify what tricks occur in the context of data visualization. This study suggests the first step in studying the case of aggressive visualization and opens the way for further research.

The Korean government is planning to introduce the Renewable Portfolio Standard (RPS) system to replace the currently used Feed-in-Tariff (FIT) system which is a subsidy-based mechanism to foster the renewable energy industry. The RPS system is a market-oriented system in which the power companies are obliged to use renewable energy sources to produce electricity by a certain ratio of their production level. They can either produce for themselves or simply purchase the REC (renewable energy certificate) in the market to implement. The objective of this article is to compare the RPS system with the current FIT system in terms of the implementing cost to achieve the policy goal to expand the share of renewable energy m the total power generation. The analysis is conducted using Linear Programming models. The results of this study imply several policy suggestions to successfully introduce the RPS system.

This paper introduces emergy(spelled with "m") that is a new environmental indicator in architecture, aiming to clarify conflicting claims of building design components in the process of energy-retrofit. Much of design practitioners' attention on low energy use in operational phases, may simply shift the lowered environmental impact within the building boundary to large consumption of energy in another area. Specifically, building energy reduction strategies without a holistic view starting from natural formation, may lead to the depletion of non-renewable geobiological sources (e.g. minerals, fossil fuels, etc.), which leaves a building with an isolated energy-efficient object. Therefore, to overcome the narrow outlook, this research discusses the total ecological impact of a building which embraces all process energy as well as environmental cost represented by emergy. A case study has been conducted to explore emergy-driven design work. In comparison with operational energy-driven scenarios, the results elucidate how energy and emergy-oriented decision-making bring about different design results, and quantify building components' emergy contribution in the end. An average-size ($101.9m^2$) single family house located in South Korea was sampled as a benchmark case, and the analysis of energy and material use was conducted for establishment of the baseline. Adoption of the small building is effective for the goal of study since this research intends to measure environmental impact according to variation of passive design elements (windows size, building orientation, wall materials) with new metric (emergy) regardless of mechanical systems. Performance simulations of operational energy were developed and analyzed separately from the calculation of emergy magnitudes in building construction, and then the total emergy demand of each proposed design was evaluated. Emergy synthesis results verify that the least operational energy scenario requires greater investment in indirect energy in construction, which clearly reveals that efficiency gains are likely to be overwhelmed by increment of material flows. This result places importance on consideration of indirect energy use underscoring necessity of emergy evaluation towards the environment-friendly building in broader sense.

The fisheries industry has been changed drastically during the so - called Golden Growth Era of Korea. Recently, WTO/DDA agenda drove industries out of their safe refuges toward infinite competitions in the world. This paper aims at finding out distinguished features in the structural changes of fisheries since 70s. Furthermore, policy implications are investigated in order for the fisheries to survive in the outdoors. The paper consists of the following sections. First, we consider why and for what the structural change of fisheries in historical perspective should be investigated. And we introduce how we can approach to the goal in various aspects in the second section. In the third section, we examine the historical change of Korean fisheries in respect of national economy, resource allocation mechanism, industrial structure, and fisheries society. In the fourth section, we extract the development steps in fisheries from the periodic characteristics, using various methods of the above approaches. And we deduce the next step for Korean fisheries in the future. Finally, we conclude that there needs some turning point of fisheries policies in Korea, striving to foster the fisheries industry in the future. As results of empirical analysis in this paper, we find that fisheries industry in Korea has experienced some momentous changes during 30 years, using I/O data of B.O.K. The weight of fisheries sector in the whole economy of Korea increased during early 70s, initially leading the national economy to export - oriented engine for growth. But fisheries sector has shrunk rapidly since late 70s. Almost resources in Korea were allocated to expanding manufacturing industries. Further, fisheries industry has encountered perfect international competitions since the late 90s. This paper draws that fisheries industry in Korea will jump across to next step of qualitative growth in the future. Therefore, we recommend that the policies should be focused on enhancing the industrial competitiveness, switching quantitative growth to qualitative advance in fisheries.

Even though 35% of Korean medical students are female, medical schools and hospitals maintain a strongly male-dominated culture which discourages female students from active career development. In 2006, Yonsei Medical school instigated an elective course entitled "Women in Medicine" to encourage and stimulate 51 female students who enrolled the course. Researchers conducted participant observations at all 6 lectures, as well as 2 surveys and 4 student fucus group discussions comprising a total of 18 students. The total satis faction r ate of the course was high at 4.6 points out of a 5-point score Nevertheless, the study results confirmed three conflict points between lectures and students. Firstly, the lecturers emphasized the excellence and carrier-goal oriented life style, whereas most students are more interested in an ordinary women doctor's life. Secondly, the lecturers emphasized the importance of husband and family's support for success in their career but most female students have little confidence in their ability to achieve a balance between work and family. Thirdly, the lecturers emphasized the women doctor who is able to lead a team effectively, but women students have few opportunities to play a leadership role in their school life. These study findings imply that there is a generation gap in the concept of "successful women doctor's life" between lecturers and students. and that interactive dialogue between lecturer and students is more important than lecture style presentations from extremely successful female doctors. In addition to such lectures, a leadership program based on active student participation should be developed.
