This paper executes positive analysis about the thesis of 100 volumes which were published for 2000-2006 years through 'Korean System Dynamics proceeding', to grope and to see the academic developments of Korean System Dynamics. The summarized analysis results are same as follows. First, Korean System Dynamics researches appear that quantitative researches are much more than qualitative ones. Second, the researches that aimed to solve problem are relatively much more than theory-oriented ones. Third, System Dynamics researches in the department of social science are more abundant than that of science and engineering. Based on these results, for establishing of Korean System Dynamics identity, we will work hard to study qualitative researches, increase the research domains and elevate the academic statue of System Dynamics.

Objective: The aim of this study is to show a correct application procedure using the compact Korean anthropometric data application program called Korean Human Scale(KHS) for anthropometric design. Background: The nation-wide anthropometric survey project called 'Size Korea' developed KHS and distributed it to the public on the web site. But some insufficiency of the current web service of KHS misleads the users; they just put their own statue and pick up a meaningless data for a body dimension. Method: This study provides five steps to follow to read appropriate data from KHS for an anthropometric design. Results: As a case study, the depth dimension of the supervisory and control console used in the Korea nuclear power plant was determined following the procedure and compared with the console design guideline recommendation. Conclusion: The supplementary anthropometry table should be added on the web service of KHS for users to read a meaningful data for design. Application: If properly used, the KHS has a lot more potential application area than users can expect such as in control center design area.

The present study investigated the concept of Buddha in 9- 12- year-old children who were in the concrete operational stage. The concept of Buddha was investigated in the following dimensions:form, competence and role of Buddha, feelings toward Buddha, and prayer to Buddha. Questionaire data were gathered from 143 children attending the Bulkwang Sunday School Statistical analysis was by Chi square. The children perceived Buddha as (1) a statue or a monk living in their mind and in heaven; and (2) unrestricted and superhuman but different from the creator, keeping an eye on them all the time and everywhere. The role of Buddha was perceived as one of giving blessing with good things to those who pray. The children had diverse feelings of awe, thankfulness, fear and anger toward Buddha. Most of the children were confident that Buddha would respond to their prayers but a few showed some doubt. Children in the concrete operational stage were less credulous than those in the pre-operational stage. More than half of the childen reported that they experience the fulfilment of their prayers. The children had deep faith in attaining Buddhahood.

The purpose of this study is to propose the efficient improvement in the lawsuit to request the guarantee against defect. This study points out several problems about related act and subordinate statue and judgement by analyzing the character of contract in apartment house, related laws and regulations, appraisals and judicial decisions. This study deduces the necessity of the establishment of the specification and the breakdown cost for repair and maintenance work to provide the standard for the detached judgement.

This paper reports the application of radiocarbon wiggle matching for Korean wooden artifacts such as furniture and Buddhist statues for precise dating. Ten biannual samples of 20 years (AD 1249-1268) for AMS (accelerator mass spectrometry) radiocarbon measurements were prepared from a board of the pedestal for Buddhist statue at Jeongsusa (temple) in Kangwhado, Korea, which was dendrochronologically dated. The average 95.4% confidence interval of radiocarbon dating without wiggle matching was 123 year. When wiggle matching technique was applied, it became 37 year, 3.3 times smaller than that without wiggle matching. The results indicated that wiggle matching technique using the calibration curve for northern hemisphere (IntCal04: International radiocarbon calibration curve announced in 2004) can produce precise dates for Korean wooden artifacts which possess as much as 20 tree rings.

Mass production of forest medicinal plants is related to quality control of raw medicinal materials. Plant tissue culture is an important technology to produce high-quality plant materials. Numerous factors are reported to influence the success of in vitro regeneration of medicinal plants. Embryogenesis is known to be the most effective techniques and it has developed in some medicinal plant species. Various in vitro cultural condition for direct and/or indirect somatic embryogenesis systems have developed in Epimedium koreaum, Bupleurum falcatum, Paeonia lactiflora, Chrysanthemum zawadskii, Houttuynia cordata etc. In this study, we provide the present statue and information of in vitro propagation techniques that is able to apply as an efficient system for rootstock propagation system of forest medicinal plants.

In Korea, the management and remedial system of the slope near national road and highway has been studied actively. But in case of the slopes exist at the residential area and local government, there is not exact record of them. So in this study, we carried out analysis about nearly 14000 slopes which were reported by local government as the dangerous area. and went to the field work some of them.

The purpose of this study is to develop and apply effective teaching strategies and program for the gifted-in-science. The teaching material for the gifted students was focussed on microscope. This study consists of three steps according to the enrichment triad model of Renzulli. Firstly, the gifted students investigate and express themselves for theological backgrounds, for examples, kinds, structure and use in various ways of microscope. It is to provide basic data for the effective ideas and interest which help students have the appropriate microscopic conceptions. In the second step, it contains understanding of a term and function of microscope, making of simple microscope, principle of a statue focusing and size estimation of an outline of subjects by scientific investigation activity. Lastly, it focussed on enlargement of post-learning through investigation of relationship with inter-science and experiments using microscope. Therefore, it was concluded that this study may help teachers reconsider scientific program development for the gifted or enriched students and to be successful in the teaching-learning processes.

수지상 구리분말은 하나의 상(statue)이 복수의 접점(contact point)를 제공하며 표면적이 넓은 구조적인 특징으로 인해 발열기판 전도성 페이스트 등 다양한 전기 전가 분야에 활용되어왔다. 때문에 본 연구에서는 전해도금방법으로 수지상 구리분말이 형성될 때 첨가제가 수지상의 형상에 어떠한 영향을 미치는지 분석하였다. 첨가제는 PEG, JGB를 사용하여 농도별로 실험을 진행하였다. SEM 이미지 분석결과 첨가제가 추가함에 따라 수지상이 미세해지며 첨가제의 농도가 증가함에 따라 DAS(dendrite arm spacing)값이 감소하여 표면적이 증가하였다. BET 비표면적 분석결과 PEG($1.882m^2/g$)보다 JGB($2.119m^2/g$)에서 표면적을 넓히는 효과가 뛰어났다.
