A forest functions classification map is an essential element for the management planning of national forests. This study was intended to make out the map at the stand level by utilizing the Forest Functions Evaluation Program(FFEP), developed by Korea Forest Research Institute. In this program, the potential of each function was evaluated in each grid cell, and then a forest functions estimation map was generated based on the optimum grid cell values in each sub-compartment unit. Finally, the program produced a forest functions classification map with consideration of the priority of the functions. The final forest functions classification map required for the national forest management planning made out overlapping those results which the rest of the forest classified referring priority functions classification map to national forest manager and classified according to the local administrative guidance and sustainable forest resources management guidance. The results indicated that the forest function classification using the FFEP program could be an efficient tool for providing the data required for national forest management planning. Also this study made a meaningful progress in the forest function classification by considering the local forest administrative guidance and sustainable forest resources management guidance.

It is necessary to diagnose the standard record management system when the system is being spread out to entire public organization and institutions. This study aims to analyze the standard record management system for improving system and revising the related standards in the future. This study evaluates the satisfaction on the interface and functional quality of the system through questionnaire survey on records managers. It is found that the satisfaction of functional quality is just above the line, but the interface fails to satisfy records managers. Also the reliability of the system appears to be higher satisfaction than efficiency and usability. Therefore, the study suggests that the standard records management systems should try to improve 'easy of use' and effectiveness and efficiency by implementing heavy batch job and promoting modulation of key function. And the study emphasizes that the standards will be revised with the long-term plan in order to develop standard records management system systematically and continuously.

The purpose of this study is to investigate the relationship between cognitive levels and achievement of science process skills. A science laboratory process skills test based on optional instrument of the SISS was administered to a sample of 162 students in the 8th grade. Practical assessment tasks consisted of the contents about acid, base, density, and a property of cobalt chloride. The format of this practical test was the station type that students had to conduct a short activity. Science process skills included three sub-skills which were categorized as designing, performing, and reasoning. As cognitive levels develop from concrete operational stage to transition stage and formal operational stage. total scores of science process skills and mean scores of sub-skills were significantly increased. Regardless of cognitive levels. all students were more successful on performing than designing or reasoning. In case of being controlled cognitive levels, gender differences and area differences were not detected in achievement of science process skills. According to these results. there was a strong relationship between cognitive levels and achievement of science process skills by practical assessment. This study implies that considering student's cognitive levels is very important for improving science process skills.

국내에서는 과거부터 현재까지 하천을 이수, 치수, 하천환경 등 기능별로 구분하여 관리해 오고 있다. 하지만 하천을 보다 합리적으로 관리하기 위해서는 종합적인 관점에서 접근이 필요하며 하천의 현 상황을 제대로 파악하는 것이 무엇보다 중요하다. 하천을 평가하기 위해 제방축조율, 수질 등 다양한 하천지표 및 평가기법들이 개발되어 왔으나 치수 이수 환경 친수 등 하천의 다양한 기능 중 특정 기능들에 대해서만 단편적으로 진단해 오고 있는 실정이다. 또한 4대강 사업, 생태하천조성 등 다양한 하천사업이 시행되고 있어 그 성과와 필요성을 정량적으로 평가 관리할 수 있는 제도 마련이 필요하며, 하천 기능을 종합적으로 진단하고 이를 객관적으로 정량화할 수 있는 체계 구축이 매우 절실하다고 할 수 있다. 따라서 건전한 하천종합관리체계 구축을 위해 하천의 기능인 이수, 치수, 하천환경 및 친수 요소간의 조화와 평가가 가능한 정량적 지표 및 지수의 개발이 필요하다. 보다 건전한 하천관리체계 구축을 위한 국가 수자원 정책 결정 시 정책결정자가 보다 다양한 정보를 획득하고 이를 통한 분석정보를 바탕으로 여러 가지 대안을 도출할 수 있어야 하며 이는 여러 가지 정보를 종합한 지표를 통해 보다 쉽게 얻을 수 있다. 하천의 다양한 기능에 대한 정보를 종합하여 지표화함으로써 정책결정자는 여러 가지 경우를 고려한 다양한 대안을 검토할 수 있게 되어 최적의 대안 도출이 가능해진다(건설교통부, 2006). 본 연구에서는 한정된 수자원을 다양한 목적과 제약조건을 충족시키면서 효율적으로 이용, 보전하기 위해 하천의 다양한 정보의 연계, 공유를 통한 통합관리체계 구축을 하고자 하천 특성을 표현할 수 있는 다수의 대리변수를 조사, 분석하였다. 또한 조사된 대리변수들 중 하천의 각 기능에 미치는 영향을 충분히 고려하여 대리변수를 선정하고 이를 통해 잠재지표를 선정하였다. 선정된 잠재지표를 이용하여 하천의 각 기능을 평가할 수 있는 하천종합관리지표를 개발하여 국내 국가하천에 적용함으로써 하천 특성의 시공간적인 변화를 분석하였다. 개발된 지표를 통해 국내 하천관련 사업에 대한 B&A 분석을 수행하여 사업 성과를 제시하였다. 본 연구에서 개발된 지표는 하천관련 사업의 전, 후 상황을 분석함으로써 사업효과를 분석할 수 있으며 하천관련 사업의 효과에 대한 대국민 홍보효과를 가져올 수 있을 것으로 사료된다.

In this study, space allocation with an assessment system for improving the function of the ecological use and function of each space was undertaken to suggest appropriate goals and directions. Ogeum Park, used as the study site, is a stronghold green zone located in the fan-shaped area of the Songpa-gu green zone on a 22ha area site. The assessment system for this study consisted of a total of 3 steps: Step 1 includes the division of the spatial block, Step 2 assesses the proper functioning of each spatial block, while Step 3 includes space allocation and presents improvements for function by space. This study performed a basin analysis with the consideration that Ogeum Park is a forest area and divided the site into a total of 8 areas according to how the sections of land are used. The function of wildlife habitat included an analysis of plant ecology(vegetation type, vegetation layer, potential vegetation), animal ecology(wild birds), and waterways. The function of leisure and use included an analysis of gradients, noise, paths, status of use, and status of facilities. The evaluation of the function of habitat sorted items into native vegetation, vegetation diversification, vegetation potential, animal diversification and potential of animal habitats. The results of grading the evaluation scores by space in the function of habitat showed that the Areas IV and VII, which were 90% of the maximum point, were Grade A, Areas II and V were Grade B at 70% and Area I and VI were Grade C at 50%. Areas III and VIII, which were not found to be beyond the standard of 50%, were excluded. The evaluation of the functions of leisure and use classified items into use potential, use preference, use concentration, use diversification and use convenience. The results of the graded evaluation scores by space in use function, showed areas V and VI as Grade A, or 90% of the maximum score. Grade B, 70% of the maximum score, was given to Areas I and VII. Grade C, 50% of the maximum score, included Areas II, IV and VIII. Area III, graded lower the standard of 50%, was excluded. The study evaluated areas according to a common standard, classified spaces by proper functions into ecological spaces, environmentally-friendly use spaces and use spaces according to the standard of spatial distribution on the basis of the above results through a synthesis of grades of habitat function, leisure function and use. This offers ideas for the improvement of wildlife habitat and environment-friendly use functions by space.

The study of ecosystem service assessment has been actively researched and developed from Millennium Ecosystem Assessment(MA) and The Economics of Ecosystems and Biodiversity(TEEB). However, current assessments are limited to monetary assessments of ecosystem function and do not account for the effects of environmental factors and socioeconomic status. This study proposes methods to evaluate ecosystem service based on environmental and socioeconomic factors. The study assesses water yield function through the water yield model in InVEST Tool, and evaluates the overall ecosystem service of water yield as reflected by the amount of precipitation and population of the area. Results show that a difference exists between spatial distributions of the ecosystem function of water yield derived from natural conditions such as land cover and soil, and the spatial distribution of the ecosystem service that accounts for climate and socioeconomic factors. The value of ecosystem service increases for an area of higher population and lower precipitation with similar water yield. Thus, the ecosystem service of water yield should be evaluated not only by the water yield function, but also by climate and socioeconomic factors. The evaluation process described for this study should also be applicable to the evaluation of ecological services in other sectors.

Objective : This study is to analyze the current trends of research and the subject and method of assessments used in praxis functions through a systematic review. Methods : Through the PubMed, Proquest, and Google database, research articles from January of 1985 through April of 2016 were searched. The keywords used for this search were "praxis AND (validity OR reliability) AND (assessment OR test) AND (preschooler OR child)". Additionally, the name for the assessments from the previous review studies of praxis function assessments was searched. In the end, 14 papers were chosen and 8 assessments that were used in these papers were analyzed. Results : Among the final 14 papers, 10 studies (71.4%) were level III (non-randomized one group) which was the largest number in this review, followed by 4 studies (28.6%) with level II (non-randomized two groups). There was no RCT study which is the level of evidence of the level I research. The results for the analysis of the subjects' age of the final 8 assessments that were chosen showed that most of the praxis function assessments were developed for children. There were 6 assessments of which their reliability and validity were verified and other 2 assessments of which their reliability and validity were not both verified. Conclusion : This study proposes the current trends of research of praxis function assessments. The study's significance is that it provides a research evidence when choosing and utilizing assessments for the children.
