The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

Is presenting guidance of information performance measurement as government PRM version 2.0 these common reference models in public sector. Government PRM is consisted of assessment classification system and standard line of sight and performance management standard form. Through this, is sorting performance element and define cause-and effect. Government PRM is supplying measurement categories at assessment classification system, but relative importance for application standard by measurement categories is not presenting. In this study, importance for government PRM's measurement categories been applying by commonness Test of information performance measurement of public sector wishes to deduce estimation and priority. Research model used Fuzzy QFD, and designed so that can reflect well PRM's development purpose. I applied Fuzzy AHP and FPP method that graft together fuzzy theory to minimize uncertainty and ambiguity in that expert opinion. Is drawn to element that "Standard model offer for information department and management" is the most important in government PRM's development purpose. "Quality of service" is showing the highest priority in customer results in measurement category. Importance for government PRM's measurement categories can offer common valuation basis in government and public institution. Hereafter if examine closely quantitative cause-and effect for structure model of measurement classification system when study government PRM more objective and efficient reference model become.

This study presents the alternative evaluation technique for the high-rise building structural system. The alternative evaluation of the structural system is performed in three steps, that is, preliminary evaluation, main evaluation and detailed evaluation. The evaluation categories are composed of structural performance, economic feasibility and term of work. Each categories are composed of detailed items to evaluate of its own. In preliminary evaluation, qualitative evaluation based on experimental knowledge is performed. In main and detailed evaluations, quantitative evaluations based on numeric data are performed. The weighted-sum method is applied to integrate the evaluated results of each items and its importance. The applicability of the proposed method was verified by applying it to the practical buildings and simulate the procedures.

국가 장기 전원개발 계획 수립에 있어서 객관적인 환경영향의 평가는 매우 중요하다. 원자력발전은 방사성 물질을 배출하는 반면, 화석연료에 의한 발전은 지구온난화 물질을 배출하는 특성을 지니고 있다. 전과정 평가방법은 연료의 채굴, 수송, 가공, 연소 그리고 폐기의 전체 과정에 걸친 환경 부하를 정량적으로 평가하는 수단이다. 본 연구는 우리나라에서 수행된 원자력발전원을 포함한 여러 전력 생산시스템에 대하여 전과정 평가방법(LCA: Life Cycle Assessmnet)을 통한 환경영향을 비교하고, 앞으로 수행되어야 할 방향을 제시하는 데 목적이 있다.(중략)

This is a comparative study that shows the overall environmental impacts from concrete structures when different compressive strength of concrete applied to structural systems having the same reference flow with different durability. A total of 24 MPa, 40 MPa and 60 MPa cases is analyzed to define the characteristic using end-point perspective LCA methodology including the stages of production, construction, maintenance and disposal. As results, global warming, non-renewable energy and respiratory inorganics problems are the major issues for assessing environmental impacts of concrete products.

In this study, life cycle assessment(LCA) for the nuclear power generation system and the thermal power generation system, which make a great distribution of the electric power supply in Korea, has been carried out to compare the environmental impact between two power generation systems. In system boundary of this study, the stage of construction, operation and demolition & disposal were included. For life cycle impact assessment(LCIA), three cases were considered; the single environmental impact for the $CO_2$ emissions, the 8 major global environmental impact, and the major global environmental impact categories including radioactive impact. As the results, it was found that the nuclear power generation system is environmentally superior to the thermal power generation system as 10,000 times in the evaluation for the $CO_2$ emissions, 90 times in the evaluation for the 8 major environmental impact categories, and 40 times in the evaluation for the environmental impact categories including radioactive impact.

To evaluate students properly in mathematics, it is essential to clarify and specify the object of study. Proper assessment tools are also needed coupled with an effective assessment method. The assessment tools have to be reasonable and trustworthy. Conducting the assessment should always produce fair and positive results and effectiveness. Establishing standards for the student evaluation competence of mathematics teachers should satisfy such objectives. Referring to the previous study suggested by Korea Institute' of Curriculum & Evaluation(KICE), this study classified the elements of capacity for evaluation competence into the general assessment, the assessment content understanding, and the assessment conduct & application areas. The specific elements of each area are established as standards. At last, 13 standards were suggested and summarized. to describe the math teachers' student evaluation competence.

Most of the studies on reduction of buildings' environmental burden in the construction industry have been focused on carbon dioxide emission, although there are various kinds of environmental issues such as global warming, acidification, and etc. which are considered by many researchers. Therefore, this study defined and suggested six impact categories and the principles to assess each impact for the assessment of comprehensive environmental impacts of buildings. The six impact categories are abiotic depletion, global warming, ozone layer depletion, acidification, eutrophication, and photochemical oxidation. A case study has been conducted through comparative analysis of two structural design alternatives to confirm the necessity of assessing the six impact categories. That is, the results of global warming potential and the six impacts proposed in this study were compared. By comparing the results of only global warming potential, the second design alternative using 24MPa concrete was chosen as a better alternative, while the first design alternative using 21MPa concrete was resulted as a better alternative when six impact categories were considered. The results mean that the assessment of various environmental impacts is an appropriate and reasonable approach and the comprehensive assessment offers more reliable results of environmental impacts in the building construction.

In this paper, we discuss the implementation of automatic internet text categorization system. A categorization algorithm is designed and the system is implemented by back propagation learning model. Internet documents are collected according to the established categories and tested by Chi-squre ($\chi^2$) for the document leaning, and the category features are extracted. The sets of learning and separating vector are productt>d by these features. As a result of experimental evaluation, we show that this system is more improved in the performance of automatic categorization than the nearest neigbor method.
