This research was conducted to evaluate whether knowledge and information resources produced in four educational institutions function as a knowledge management system in the institutions, and to suggest a proposed plan for the foundation of the national knowledge management system. Knowledge and information resources available on the institutes' websites were classified as 'knowledge and information resources of result', 'knowledge and information resources of process', and 'knowledge and information resources of communication'. The application of metadata and the configuration of the search system were examined by content analysis method. From the result, 8 ways to improve the management of knowledge and information resources have been found; the development of standardized metadata and classification scheme, high recognition that the website is a counter for external distribution of knowledge and information resources, various searching skills and the provision of knowledge maps available, provision of linked information for original information acquisition, awareness of the agency managers and homepage managers to the homepages as knowledge management systems, segmentation of appropriate data size unit in a mobile environment work, an organic linkage function of the internal electronic approval system and the homepage have been proposed.

In order to establish the causes and measures for technical risks that occur in various ground conditions when a subsea tunnel is excavated, it is important to configure expected risk scenarios. In addition, when the risk scenarios are classified because the scenario that occurs along all tunnel route and the scenario limited to some area are considered together, a logical framework with systematic and organized responses can be provided for project managements. In this research, project risk scenarios and management elements were configurated, and the project schedule was established for the management techniques to the risk scenario. The risk scenarios expected in a subsea tunnel were classified into a common risk scenario and a special risk scenario, and the concept which can combine with the project management elements was derived.

It has been recently emphasized that comprehensive understanding of students' cognitive activities in the process of writing as well as final product is needed in order to develop an effective strategy for science writing. In this study, we investigated the characteristics of writing process in the situation that students wrote a composition in solving the application problem on a science topic. Seven eighth graders selected in the consideration of their science achievement and communication skills were asked to write a composition using think-aloud method. They were also interviewed after their writing work. The analyses of the results indicated that students' writing processes consisted of six distinctive components: generating, organizing, setting, translating, evaluating, and revising. It was also found that the patterns of process components for each student were different in terms of the frequency and the sequence. The patterns of process components were categorized into four types: systematic, tacit planning, trial and error, and random strategies. Educational implications were also discussed.

Phytoliths, silica microfossil that produced within and between cells and tissues of plants are especially yielded in Gramineae with many different forms and can attribute to the reconstruction of climatic and environmental changes and agriculture activity of the Quaternary. The phytoliths in soil can remain for long periods of time, because of strong resistance to physical and chemical weathering. The spatial range of study is too small due to deposition of phytoliths directly to the soil. There are difficulties of phytoliths identification because of multiplicity and redundancy, so far uniform and exact classification scheme has not been adopted. Therefore we attempted phytolith classification system applied to Korea. The paleoenvironmental reconstruction research using phytholith are applicated in many parts of studies. Also high-resolution paleoclimatic reconstruction expected to be possible using phytolith indices of Iph and Ic as well as climatic indicator of phytolith morphology.

This study aims to analyze the influence of organizational support perception of workers in medical institutions on intrinsic job motivation, and to check whether there is significance in the mediating effect of work-family conflict and work-family balance factors in this process. The results of empirical analysis through the questionnaire are as follows. First, it was confirmed that organizational support recognition had a significant positive effect on work-family balance as well as intrinsic job motivation, and work-family balance had a significant positive effect on intrinsic job motivation. Second, it was confirmed that organizational support recognition had a significant negative effect on work-family conflict, but work-family conflict had no significant influence on intrinsic job motivation. Third, in order to reduce job stress for medical institution workers, it is necessary to reduce job intensity, assign appropriate workload for ability. And in order to improve manpower operation and job efficiency, Job training and staffing in the right place are needed. Fourth, in order to improve positive organizational support perception and intrinsic job motivation, It is necessary to induce long-term service by providing support and institutional devices to increase attachment to the current job and recognize organizational problems as their own problems with various incentive systems. The limitations of this study and future research directions are as follows. First, it is believed that an expanded analysis of medical institution workers nationwide by region, gender, medical institution, academic, and income will not only provide more valuable results, but also evaluate the quality of medical services. Second, it is necessary to reflect the impact of the work-life balance support system on each employee depending on the environmental uncertainty or degree of competition in the hospital to which medical institution workers belong. Third, organizational support perception will be recognized differently depending on organizational culture and organizational type, and organizational size and work characteristics, working years, and work types, so it is necessary to reflect this. Fourth, it is necessary to analyze various new personnel management techniques such as hospital's organizational structure, job design, organizational support method, motivational approach, and personnel evaluation method in line with the recent change in the government's medical institution policy and the global business environment. It is also considered important to analyze by reflecting recent and near future medical trends.

최근 한국사회에서는 출산율의 저하로 인한 사회경제적 영향을 우려하여 대책방안을 강구하여야 한다는 논의가 증대되고 있다. 그런데 국가정책을 개발${\cdot}$추진하기 이전에 반드시 요구되는 것은 저출산 현상의 올바른 인식과 철저한 원인규명이다. 따라서 본 연구에서는 출산율 변화의 원인을 다각적으로 살펴보고, 향후 변화방향을 전망해 보고자 한다. 먼저 자녀출산의 변화를 결혼상태 변화와 유배우부인의 출산율 변화 부분으로 나누어 살펴본 결과, 과거와는 달리 최근의 출산율 저하는 유배우 부인에 의해서가 아니라 미혼자의 결혼연장 또는 독신생활에서 기인되는 것으로 나타났다. 이들 두 요인에 영향을 주는 변수로는 경기침체 및 직장불안정, 결혼가치관의 변화와 초혼연령의 상승, 자녀양육 관심증대, 자녀양육비 부담, 가정과 직장의 양립을 위한 사회적 인프라 부족, 여성의 자아욕구 및 사회참여 증대, 자녀효용가치 감소, 이혼 등 가족해체의 증대, 그리고 불임부부의 증대 등인 것으로 판단된다. 향후 출산율 변화를 전망해 보면, 저출산을 일찍 경험한 서구 선진국의 경우와는 달리 정책의 추진에 한계가 있어 선진국보다 더 낮은 출산율을 회복하는 데는 많은 어려움이 있을 것이라는 판단이다. 더군다나 젊은 미혼남녀의 가치관이 개인주의화 되는 경향이 있다는 점을 감안한다면 출산율 회복정책을 추진한다 하더라도 한계가 있을 수밖에 없을 것이다. 수년간 실시된 각종 실태조사를 분석한 결과에 의하면 현재의 경기침체가 회복될 경우 약 20%의 출산율 상승 가능성이 있으며, 이 때의 합계출산율은 약 1.43명 수준이 될 수 있을 것으로 예견된다. 또한 종합적 체계적 출산회복정책을 효과적${\cdot}$효율적으로 추진한다면 약 10년 후에는 합계출산율이 약 1.6 수준으로 회복될 것이라는 낙관적 견해를 가져본다. 그렇지만 정책의 강도에 따라서 회복수준은 현저하게 상이할 것이다.를 진단, 치료함에 있어 진행성 신질환의 가능성을 시사하는 예후인자가 없다면 신생검보다는 지속적이고 정기적인 추적관찰만으로도 충분할 것으로 생각된다도 등은 양군 사이에 유의한 차이가 관찰되지 않았다. 발견 당시 혈청 $C_3$치의 감소는 모두 11명(61.1%)에서 관찰되었는데, 증상군에서는 7명(87.5%), 집단뇨검사군에서는 4명(40%)으로 증상군에서 혈청 $C_3$치의 감소가 보다 현저하였다. 그러나 추적관찰 기간 동안 증상군에서는 7명 중 4명, 집단뇨검사군에서는 4명 중 1명에서 혈청 $C_3$치는 정상범위로 증가하여 최종 관찰시점에서는 6명 (33.3%)에서만 혈청 $C_3$치의 감소가 지속되고 있다. 혈청 $C_3$치의 감소를 보인 경우를 다시 병리조직학적 분류에 의해 세분하여보면 발병당시에는 I형 8명(61.5%), II형에 1명(100%), III형 2명(50%)에서 관찰되었는데, 최종 시점에서는 I형 4명(30.8%), II형 1명(100%), III형 1명(33.3%)이었다. 또한 증상군에서 세포성 반월체형성과 세뇨관위축의 빈도가 높았으며, 사구체 혈관벽 비후와 사구체 간질의 증가의 정도가 집단뇨검사군에 비해 통계적으로 유의하게 높았다. 결론: 무증상성 요이상을 가진 환자에서 신장조직검사 실시 후 MPGN으로 진단되는 증례가 증가하고 있고, 오히려 증상을 동반하는 경우보다 빈도가 증가한다는 사실은 집단뇨 검사에서 소변의 이상소견이 발견되어 신장 조직검사를 실시할 경우 혈청 $C_3$치의 감소 여부에 관계없이 MPGN도 진단적 고려 대상이 되어야 한다고 생각한다.신장 조직검사를 시행한 결과 진행성 경과를 취할 수 있는 막 증식성 사구체 신염과 매우 희귀한 증례인 신유전분증 등으로 진단됨으로써 지속성 단백뇨의 경우 정확 진단적 접근이 필수적임을 알 수

The calcifying odontogenic cyst(COC) showed diverse terminology or classification, clinicopathologic features as well as in its biologic behavior, although it was recognized as a distinct clinicopathologic entity. The epithelial lining of a COC appears to have the ability to induce the formation of dental tissues in the adjacent connective tissue wall, and that other odontogenic tumors may sometimes be associated with it. This case is a COC associated with a complex odontoma involving an impacted left maxillary lateral incisor in a 5-year-old female child. Radiographic examination revealed a well-demarcated radiolucent lesion partially occupied by a radiopaque mass, involving the left lateral incisor crown. The histologic sections showed a cystic cavity lined with ameloblastic epithelium containing ghost cell masses with admixed with complex odontoma components. The presence of mixed radiolucent-radiopaque lesion in children as observed in this case, the possibility of COC must be considered. In this case, there was no recurrence 1 year after enucleation and the space control is ongoing now.

In this paper, it was found that most of the machinery facilities problems generated by clients could be prevented in advance by systematically managing the mechanical equipment production process of small and medium enterprises (SMEs) that produce machinery facilities. Major point of this process is to establish an operating system that corresponds to reality of facility manufacturers as it represents 63% of machinery facilities problems that occur in customers and is a task that needs to be solved most intensively. Technical issues account for 23% of machinery facilities problems occurring at the client's companies and should be approached from a long-term perspective as they are directly related to the technical capabilities of the manufacturers. Organizational problems account for 14% of machinery facilities problems occurring in customer companies, and can change depending on the relationship of members and the nature of the human being, such as morality and motivation. In addition, we propose the establishment of an Internet-based production process management platform for smooth and efficient transfer of information between customers and machinery facilities manufacturers.

Although various models have been developed to establish the enterprise credit scoring, no model has utilized the enterprise human resource so far. The purpose of this study was to build an enterprise credit scoring model using enterprise human resource factors. The data to measure the enterprise credit score were made by the first-year research material of HCCP was used to investigate the enterprise human resource and 2004 Credit Rating Score generated from KIS-Credit Scoring Model. The independent variables were chosen among questionnaires of HCCP based on Mclagan(1989)'s HR wheel model, and the credit score of Korean Information Service was used for the dependent variables. The statistical method used for data analysis was logistic regression. As a result of constructing a model, 22 variables were selected. To see these specifically by each large area, 6 variables in human resource development(HRD) area, 15 in human resource management(HRM) area, and 1 in the other area were chosen. As a consequence of 10 fold cross validation, misclassification rate and G-mean were 30.81 and 68.27 respectively. Decile having the highest response rate was bigger than the one having the lowest response rate by 6.08 times, and had a tendency to decrease. Therefore, the result of study showed that the proposed model was appropriate to measure enterprise credit score using enterprise human resource variables.

Purpose : The main Purpose of this study is to develop new payment rates for services of Radiation Oncology, considering costs of treating patients. Material and Methods : A survey of forty hospitals has been conducted in order to analyze the costs of treating patients. Before conducting the survey, we evaluated and reclassified the individual service items currently using as Payments units on the fee-for-service reimbursement system. This study embodies the analysis of replies received from the twenty four hospitals. The survey contains informations about the hospitals' costs of 1995 for the reclassified service items on Radiation Oncology. After we adjust the hospital costs by the operating rate of medical equipment, we compare the adjusted costs with the current Payment rates of individual services. Results : The current payment rates were 5.05-6.58 times lower than the adjusted costs in treatment planning services, 2.22 times lower in block making service, 1.57-2.86 times lower in external beam irradiation services, 3.82-5.01 times lower in intracavitary and interstitial irradiation and 1.12-2.55 times lower in total body irradiation. Conclusion : We could conclude that the current payment system on Radiation Oncology does not only reflect the costs of treating patients appropriately but also classify the service items correctly. For an example, when the appropriate costs and classification are applied to TBI, the payment rates of TBI should be increased five times more than current level.
