In order to determine the best operating rules for the Nakdong River, three cases were applied to analyze the simulated results of water supply capacity by HEC-ResSim model. This study discussed to present the best operating rules for conjunctive operating of existing the dams and new constructed the weirs through system network. The system network was constructed considering the water supply, the river environment and the operating facility. The water supply capacities are separately evaluated for each case applying the best rules. It is case1 that the dams are operated individually, case2 that the dams are operated in conjunction with the others dams, and case3 that dams and weirs are operated in conjunction with the others dams-weirs. Comparing the cases, case 3 has shown the best water supply capacity of the Nakdong River.

After the Industrial Revolution. most of experimental houses were had focused on the way of construction structure and material of buildings. Especially the Case Study Houses among experimental house of the mid-twentieth century were appreciated as an important case in a viewpoint of technology space and aesthetics. The Case Study Houses program was started by the sponsorship of magazinein California 1945 after the World War II. From 1945 to 1966. for about 20years more than 36 house projects were progressed by the Case study House Program This research divided and organized the expression characteristics of the Case Study Houses' technical spacious and artistic aspects. As a result the experimental housing concept that was established within the Case Study Houses became the remarkable concept of the modern architecture that is successfully accomplished within the frame of housing.

The purpose of this research is to examine track suits which appear in mass media and to attempt to understand their embedded symbolism. Hence, a theoretical inquiry and case study on suit tracks were carried out. The case study was confined to the period since 2000, when sportswear emerged as a megatrend in fashion, to 2012. Occurrences of track suits in film, TV dramas, music videos, advertisements, and fashion collections were examined. Research indicated that the track suits in film or TV drama worked as items to give a change to coordination, material and decoration, so that the track suits highlighted the characters in them rather than emphasizing external factors or their own design. They were used as tools to indicate the sensual and dynamical feminine image in the rap and hip hop genres in music video. They also showed the dynamic image of modern woman via advertisements of sports brands. In the case of celebrity fashion, both inside and outside Korea, they introduced the track suits in a comfortable and sensual manner through both official and unofficial image releases. In the fashion collections, transboundary deconstructiveness was strongly expressed in terms of design, material, color, and production method. The case study in this research indicated that the symbolism in track suits was characterized as transboundary deconstruction as well as value in dynamic femininity, and products from reactionary nostalgia.

In this study, we introduced the concept of ‘case-method’ which is the method to discuss about actual education with a concrete case. And we suggested that case-method need to be applied a program for mathematics teacher professional development. To assist this suggestion, we attempted to examine recent mathematics educational studies that is written by case-study and topics that is included in mathematics teacher educational program. After these examination, we pointed out that case-method with a educational case have not applied in teacher education program in korea. According to the suggestion in this study, we showed a concrete example of case-method. In this example, we set up three perspectives(on general theory of mathematics education, on contents of given case, on application given case to own class) to analysis given case and revealed several disscussion topics each perspective. Finally, we referred to the following research of this paper.

The engineering design is very important to make the building of engineering mind in many industry companies because most of companies require commonly the talents for engineering design in order to have originality, reliability and responsibility for university students. But, it can be thought that most of students studying engineering fields in Korea can not have their talents for engineering design in major fields of university sufficiently due to traditional engineering education method. In this paper, a case study of the teaching method for the 'esearch problem' that means capstone design in engineering education is suggested to improve the teaching skills for various engineering based fields. In this paper, a case study of teaching method in research problem for engineering design is shown in order to improve the teaching method for the design in engineering fields.

Including technical device and general information system, the information-technical(IT) system is defined as the technical system for acquiring, processing, storing and transferring information to a person. This paper presents Knowledge-based Heuristic Evolution Model for creating the advanced information-technical system. This Evolution Model is derived from the historical review on definition of evolution, the research on the architecture of the general IT system, history of IT system, technology innovation theory and multi-case study research. The evolution model is applicable to the conceptual creation of the advanced product in R&D organization requiring development methodologies like rapid-prototyping to develop next generation product. For the detailed theoretical construction and practical application of Evolution Model, the case study research based on action research is performed. the object of the case study is mobile device, especially mobile hand-held phone. Thus, we obtain the Evolution Model for creating the advanced information-technical system.

The Earthquake Case Study and Disasters Information System based on GIS (MapECDIS 2002 for Windows), sponsored by Science and Technique Ministry of CHINA, is a GIS system developed to provide a tool for the government and the public to query and comprehend the disaster information (since 2221BC) and case study results (since 1966) of destructive earthquakes occurred in China. The system is expected to be useful for the earthquake forecast practice, the seismology research and earthquake disasters research as an applied assistant tool. The design idea and main functions of the system are introduced in the paper.

The purpose of this paper is to introduce the development of a new Lesson Video-Case Lab (LVCL) program in Suzhou, China. This program involves the creation of several series of hypermedia video-cases on teaching and learning designed to facilitate mathematics teachers' professional development. Each of these video-cases consists of lesson clips, case questions, interviews with experts, comments by peers, responses by students and other related resources. The study has implications pertaining to the use of technology in teacher development, the production of hypermedia video-cases, as well as research on case-based pedagogy and pedagogy in general.

The final decision of study design in molecular and genetic epidemiology is usually a compromise between the research study aims and a number of logistical and ethical barriers that may limit the feasibility of the study or the interpretation of results. Although biomarker measurements may improve exposure or disease assessments, it is necessary to address the possibility that biomarker measurement inserts additional sources of misclassification and confounding that may lead to inconsistencies across the research literature. Studies targeting multi-causal diseases and investigating gene-environment interactions must not only meet the needs of a traditional epidemiologic study but also the needs of the biomarker investigation. This paper is intended to highlight the major issues that need to be considered when developing an epidemiologic study utilizing biomarkers. These issues covers from molecular and genetic epidemiology (MGE) study designs including cross-sectional, cohort, case-control, clinical trials, nested case-control, and case-only studies to matching the study design to the MGE research goals. This review summarizes logistical barriers and the most common epidemiological study designs most relevant to MGE and describes the strengths and limitations of each approach in the context of common MGE research aims to meet specific MEG objectives.
