The purpose of this study was to review the studies related to the problem of context in science education. Firstly, studies on context and context effects in science education (and also those related in cognitive psychology) were summarized according to the topics concerning science learning, such as deductive reasoning and probabilistic judgement, controlling variables, scientific inquiry skills, memory and consistency of misconceptions, selecting cognitive strategies and problem solving, achievement and momentum effect, and interest, religion and culture. Secondly, the common problems appeared from the analysis of the studies were discussed, such as (1) how to define contexts?, (2) how to classify contexts?, (3) how to characterize the effects of contexts? and (4) how to explain the context effects? Finally, the implications of the analysis of the studies on the problem of context were discussed in terms of recent development of science education, such as misconception studies, STS science education and the application of the history of science to science teaching.

The purpose of this study was to introduce major contents and examine the feminist social work practice. Feminist social work practice has never been introduced and applied to social work fields in Korea. By contrast, it has been developed and expanded in advanced Western countries. Feminist social work was emerged under the influence of worldwide Women's Movement on the end of 1960's. After the time, there were critics of existing social work practice by feminist, increase in interest of women's issues, development of principles and methods in feminist social work practice. Feminist social work practice brought, transformative change, application of gender perspectives to social work practice. Also, it offered the visions for 'integrative practice', accepted the alternative principles and methods, and enriched 'theory-practice'. As the result, feminist social work practice contributed to solving or alleviating the problems of many clients, especially women clients. These evidences suggest that feminist social work practice has the possibility of holding an position as a new alternative social work practice.

The main objective of this research is to identify the evaluation criteria of the local governments' projects for the fisheries industry development (LGPFID) and to develop the evaluation software prototype applicable to LGPFID. This research does not try to develop the whole evaluation processes and programs for LGPFID, but just to outline the approach to managing LGPFID. The evaluation processes and programs developed in this study is based on the group decision support systems(GDSS), which is a collaborative, system-oriented, and objective system useful in evaluating LGPFID. Specifically the goals of the programs are to : (1) enhance the quality of evaluation process for LGPFID; (2) provide the local government decision makers' and interest groups' access to comprehensive evaluation information; (3) support private-public collaboration in government's decision making. We used analytic hierarchy process model as a group decision making model and programmed the application software prototype with Visual Basic language.

The aim is to get comprehensive view point for the price of apartment. Apartment construction cost is the sun of land cost and building cost. Land price reflects the value of location where building stands. When the gap between price and affordability is narrow enough, effective demand promote apartment construction. The today's trends of rising price, which began in apartment housing, spreads to real estates market and finally overall consumer price. Problem is that price is decided only by supplier's interest. Equilibrium-pricing is common process in housing market. However it is important to review hedonic price and the factor of housing services and focused on the affordability of demanders. AHP analysis was used to study real needs and preference of demanders and dealt with 200 interviewees with brief checklists. We found that social factor is more important than building cost or site development. Especially location of apartment is most important to affect environment quality and accessibility to facilities.

Recent increase in the interest and adoption of BIM for infrastructure projects has created a need for formal BIM guidelines in the civil engineering domain. Currently a BIM guideline has been developed in Korea exclusively for the road sector. However, the guideline has gaps in the specification of how BIM models should be generated, managed and applied for maximum effect in projects. This study reviewed the guidelines and tender documents of Singapore to determine potential improvements to adopt in Korea. Results showed that Korea's guideline should focus more on process integration as to stipulating BIM deliverables, encourage a common data environment, clearly distinguish between compulsory and selective BIM applications, and require data and models that can be leveraged in the operation phase of the facility.

In the present study, a solution algorithm for the computation of unsteady flows on unstructured meshes is presented. Dual time stepping is incorporated to achieve the second-order temporal accuracy while reducing errors associated with linearization and factorization. This allows any time step size, which is suitable for considering physical phenomena of interest. The Gauss-Seidel scheme is used to solve the linear system of equations. A special treatment based on spring analogy is made to handle meshes with high aspect-ratio cells. The present method was validated by comparing the results with experimental data and those obtained from rigid motion.

In this paper, the instrument for scientific education in elementary school is developed with the application of basic robot technology for coming IT future world. Particularly, a kind of robot game to fun a race with each other is planed to give a motive or interest in scientific education. This robot game is played with two robots per player, One robot is moved wirelessly with a remote controller and the other robot is moved automatically with intelligence given by computer program made by a player. This game system will be in spotlight as multi-objective educational system not only to teach basic technology of IT, but also to improve the ability for logical and creative thought in elementary school students.

In the recent years, as the research and the development of micro and precision machinery become active, the interest of micro actuators using SMA(Shape Memory Alloy) has been increased. The dynamic characteristic analysis of SMA is necessary for actuator application and many common researches report the material characteristics of SMA sufficiently. However, the research on dynamic characteristics is very deficient. In this paper, the helical spring are fabricated with NiTi SMA wire of high resistivity. The force, response speed, temperature, and displacement are measured by digital force gauge, infrared thermometer, and laser displacement sensor so that the dynamic characteristics of this SMA is analyzed. Also, bidirectional actuator was fabricated and experimented for its performance.

Recently, engineering work become very important for the leaders of the information society for the future knowledge in the 21st century and the goal of engineering education is to prepare people to practice engineering as a profession and also to spread technological literacy, increase student interest in technical careers through science and math education. The College of Engineering (COE) of Korea Maritime University (KMU) aims to be the center of both IT-related high industrial technology and the industries related to port, shipbuilding and the ocean. Especially COE focuses on the educational principles to contribute to the development of the country and the regional communities by educating specialists that have international competitiveness. With the need to expand international collaboration in terms of engineering work, it is proposed to initiate a new state of the Asian-Pacific body of engineering conference. To the extent possible the basic discussion was made to expose elements and supports as full-scale illustration of the engineering conference. The result is a body that evokes multi agreement and joint declaration among members.
