The purpose of this stud)r was to critically review the trends of research methodologies of environmental education. We analyzed Journal of Korean Society for Environmental Education (vol. 1 ∼vol. 14(1)) and The Journal of Environmental Education(vol. 25∼vol. 31) to investigate the trends of methodology in EE research of Korean and other countries and to explore the tasks of it. The findings were as follows, 1) More than half of the character of the papers in Korea were actual condition (54.38%), substitute proposal (32.12%), and the papers in others countries were actual condition (39.35%), substitute proposal (33.55%). 2) The major parts of the method of the papers in Korea were literature review (26.05%), survey research (23.79%), on the other hand the papers in other counties were survey research (42.70%), literature review (25.84%). The results indicated that the research methodologies of environmental education in Korea were needed to be reinforced in the field of qualitative and quantitative research methods.

A DF (Directory Facilitator) provides yellow pages services for other agents in agent platform. That is to say, the agents are able to register the descriptions of the services they provide for DF or inquire DF about the services other agents provide. The Current DF cannot federate with heterogeneous agent platforms. Because DF is not opened to the other DF in the heterogeneous agent platform, it is need to something about federation technology between them. Thus, we propose the database server for the federation technology among DFs. The main purpose of the database server is to provide the environment where agents can register their services and search about the services that other agents on the heterogeneous platform provide.

Electronic equipments and make other electronic systems to operate abnormally by means of electromagnetic interference, or can operate abnormally themselves by electromagnetic interference of other electronic systems. Therefore, electronic equipments are required to reduce their electromagnetic interference as small as for other systems to operate properly and operate properly within electromagnetic interference from other electronic systems. In order to prove that electronic equipments meet such requirements, they should undergo electromagnetic environmental test. In this study, we introduce electromagnetic environmental requirements, test procedures and test results of gimbal engine actuation system of KSR-III.

The characteristic fitness of food to each Sa-sang constitution and the relationship between Han-Yeoul characteristics and chemical composition after classifying Samgye-tang ingredients and other food into Ohn-Yeoul-Ryang-Han characteristic were assessed. When the suitable constitution to the each characteristic was investigated after classifying Samgye-tang ingredients and other food into Han, Ryang, Pyound, Ohn and Yeoul of which fitness case for Soeumin was 44∼63% but fitness case for Soyangin and Taeyangin was only 0∼18%. When the relationship between Samgye-tang ingredients and other food classified into Ohn-Yeoul-Ryang-Han and chemical composition of fatty acid, amino acid, vitamin and mineral was investigated, the value of correlation coefficient was extremely low. There was not the relationship between chemical composition and Han-Yeoul classification. Therefore it should be further investigated the relationship between characteristic and chemical composition by additional analysis index.

To analyze the effect of reminder type on the development of time-based prospective memory of children, 270(90 each 5-, 7-, and 9-year old) participants were randomly divided by age group into three subgroups : self-cued reminder, other-cued reminder, and control groups. Results showed that the performance of time-based prospective memory significantly increased with age, and the presentation of reminders was effective for improving the performance of time-based prospective memory. For younger children the presentation of other-cued reminder was more effective than self-cued reminder, but for the older children, presentation of self-cued reminder was more effective than other-cued reminder.

In the present paper, flow fields around two dimensional single and two circular cylinders are analysed by a finite difference method. Navier-Stokes and the continuity equations an solved to simulate the flow fields. A overlapped grid system(the composite of a body boundary-fitted grid system near the body and a rectangular grid system for other flow fields) is used for this calculation. In the use of overlapped grid system, it is most significant thing to exchange the physical quantities from one grid system to the other one continuously, In this research, the linear interpolations of physical quantaties are done for this purpose in the overlapped region. The numerical calculations are carried out for the flows around a circular cylinder and two cylinders to verify the accuracy of present method. The flow fields around two cylinders facing the flow with side by side and tandem arrangement are analysed. The results are compared to other experimental and computational ones done in other single grid system.

According to the Bank Profitabilities Statistics of OECD members, Our domestic banks applying commissions for both exchange and selling/buying foreign currencies are evaluated as much higher than those of other countries banks. The theory indicates an analysis results and comparison in between banks over the world. Our domestic bank assert that, in general, the aggregated banking commission income is lower than those of other countries by comparing in the field of non-interests profits. Viewing by another analysis in details, some commission rate applying to domestic services are far below than cost basis, but other commission rate applying to foreign currency transaction services is abnormally higher. Such unfair rate should be lowered to the similar level to other banks in the world and also the actual cost should be reasonably reevaluated in the reasonable manner. One more thing, The writer suggest that domestic banks should spend efforts to increase their income by improving and diversifying with the various type of new commissions applied to domestic market, such as multi-functional financial services, expanding ATM services, electronic settling technique etc under today's rapidly changing and opening world financial market.

In distributed autonomous robotic systems (DARS), each robot must behave by itself according to its states ad environments, and if necessary, must cooperate with other robots in order to carry out their given tasks. Its most significant merit is that they determine their behavior independently, and cooperate with other robots in order to perform the given tasks. Especially, in DARS, it is essential for each robot to have evolution ability in order to increase the performance of system. In this paper, a schema co-evolutionary algorithm is proposed for the evolution of collective autonomous mobile robots. Each robot exchanges the information, chromosome used in this algorithm, through communication with other robots. Each robot diffuses its chromosome to two or more robots, receives other robot's chromosome and creates new species. Therefore if one robot receives another robot's chromosome, the robot creates new chromosome. We verify the effectiveness of the proposed algorithm by applying it to cooperative search problem.

Although the microfinance sector in Bangladesh is mainly driven by Non-Governmental-Organizations (NGOs), there are other types of Microfinance Institutions (MFIs) that also provide financial services to the poor. Despite the criticism of microfinance programs, the current poverty situation in Bangladesh still requires such programs for consistently battling poverty. Hence, the aim of this paper is to profile the microfinance sector based on their legal status and investigate any possible differences (if any) between them in various aspects. After a thorough investigation of the sector, it was found that around 33 million of the clients are being served by the mainstream MFIs (NGO and Grameen Bank) while another 10-15 million clients are served by other types of MFIs (financial cooperatives, credit unions, various ministries etc.), accounting for the one-third of the total population in Bangladesh. While the mainstream MFIs basically works with poor, other categories of MFIs are concerned with relatively wealthy clients. Looking into the financial performance and social intermediation of the MFIs, the NGO-MFIs performed better than other types of MFIs in the sector.

During one year period from Sep. 1986 to Sep. 1987, we have experienced 6 cases of infective endocarditis requiring surgical interventions. All 6 patients had class IV or V cardiac disability at the time of surgery. The indication for surgery was rapidly progressive congestive heart failure in all cases. Four patients underwent aortic valve replacement including one double valve replacement. Two other patients required other surgical procedures, removal of large left atrial vegetation mass in one patient and excision of destroyed pulmonary valve and aortic vegetation in the other patient. Two patients died; one of mitral annulus rupture after release of aortic clamp and the other of mediastinal bleeding 3 months after replacement of aortic valve. Three out of 4 survivors are in NYHA Class I and the remaining patient is in Class II. We emphasize that early operative intervention is life-saving in patients with persistent or progressive congestive heart failure, irrespective of the activity of the infective process or the duration of antibiotic therapy.
