This paper proposes an improvement to differentiate assessment procedure for projects in consideration of their environmental impact as a means to improve efficiency in environmental impact assessment ("EIA") procedure. The targets of analysis were limited to lower impact projects. The current EA system in Korea has already attempted to introduce separate proceedings for certain projects.Tangible results from these efforts, however, have been limited. Other countries have adopted a "screening" system to determine whether EIA is applicable to a particular project, and if so, what procedure will be used therein. Therefore, this study suggests the screening as the process wherein need for EIA is determined with respect to projects which have undergone Prior Environmental Review System(PERS) and which appear to have comparatively negligible environmental impact. In this case, EIA can be omitted and the developer can then draft a mitigation plan instead. This study found that exempting certain projects deemed as having low environmental impact can considerably shorten the duration required for both environmental assessment and consultation, thereby improving efficiency. Other expected effects from the adoption of this screening include reduction in delays in project execution due to environmental assessments and reduced red tape through the provision of increased autonomy to developers and the approving authorities.

The purpose of this study was to develop the environmental management strategy of streams based on the quantified evaluation method of the stream environment. The six streams in Jinju city flowing into the Nam-river were selected for the case study. The stream environment evaluation was performed considering the following three independent field surveys. First, the stream naturalnesses considering 20 evaluation elements were investigated for each unit section of the streams having the length of 500m and the width of 100m, and then were evaluated into 5 grades. Second, water qualities of the streams were evaluated into 5 grades based on the results of eight times water quality survey. Third, the landuse patterns in the stream basins were evaluated into 5 grades according to the residential area ratio. Finally, the stream environments were classified into 5 grades by integrating the above three subfactors - stream naturalness, water quality, and residential landuse. According to the evaluation results of stream environments, the three environmental management strategies of streams were suggested. As the results of the case study, Panmun stream and Ghajwa stream were evaluated to the forth grade that need active environmental restoration, and Nabul stream and Yonga stream were evaluated to the second grade that need partial environmental restoration while Youngchun river and Dogsan stream were evaluated to the first grade showing the desirable stream environmental condition. The above environmental evaluation results for each stream will be an important reference for the further stream restoration or management plan.

The purpose of this study is to improve the previous groundwater contamination vulnerability assessment method, apply it to the study area, and select priority areas for groundwater management based on the quantitative analysis of groundwater contamination vulnerability. For this purpose, first, the previous 'potential contamination' based on groundwater contamination vulnerability assessment method was upgraded to the methodology considering 'adaptation capacity' which reduced contamination. Second, the weight of groundwater contamination vulnerability assessment factors was calculated based on the analytical hierarchy process(AHP) and the result of survey targeting groundwater experts. Third, Gyeonggi-do was selected as the study area and the improved methodology and weight were implemented with GIS and actual groundwater contamination vulnerability assessment was carried out. Fourth, the priority area for groundwater contamination management was selected based on the quantitative groundwater contamination vulnerability assessment diagram. The improved detailed groundwater contamination vulnerability assessment factors in this study were a total of 15 factors, and 15 factors were analyzed as new and improved weight with higher 'adaptation capacity' than the assessment factor corresponding to the previous 'potential contamination' in the weight calculation result using AHP. Also, the result of groundwater contamination vulnerability assessment in Gyeonggi Province using GIS showed that Goyang and Gwangmyeong which were adjacent to Seoul had a high groundwater contamination vulnerability and Pocheon and Yangpyeong County had a relatively low groundwater contamination vulnerability. In this study, the previous groundwater contamination vulnerability assessment was improved and applied to study areas actually. The result of this study can be utilized both directly and indirectly for the groundwater management master plan at national and local government level in the future.

이 연구는 현존해 있는 다양한 임상평가도구의 신뢰도와 타당도에 관한 분석 서술 연구이다. Rines(1974)에 의하면 평가는 학습경험을 통하여 목적을 달성하는 지의 여부를 측정하는 것이라고 하였고 평가의 목적은 교육증진을 도모하며, 목표를 설정하고, 학생의 학습진행과정을 사정하여 학생들을 위한 프로그램을 사정, 개발시키는데 있다고 피력 하였다. 간호교육에는 실무교육이 많은 비중을 차지하고 있다. 또한 많은 간호교육자들은 실습평가에 있어 많은 어려움을 경첩하고 있다. 이러한 난해한 실습평가도구를 개발하기 위하여 선행된 우선순위로써 현존해 있는 다양한 평가도구의 신뢰도와 타당도를 평가하는 것이 의의 있는 일이라 사료된다. 이 논문은 실습평가도구의 신뢰도와 타당도에 관심을 가진 임상지도교수나 간호교육자들을 대상으로 한 서술적 연구이다. 우선 간호교육평가에 있어서의 문제점을 분석하고 평가도구에 대한 전문가(Authority)의 의견을 피력한 다음 저자의 의견을 서술하였다. 결론적으로 현재까지 개발된 완전한 임상실습평가의 방법은 없다. 그러므로 현존해 있는 평가방법을 서술평가하고 문제점을 지적하므로써 질적인 평가도구개발에 도움을 줄 수 있다. 앞으로 간호교육자들이 각 문제점들을 보완하여 교육목적을 달성시킬 수 있는 효율적인 평가도구를 개발하는 것이 급선무이다.

This research analyzed acceptability of local public enterprise management assessment targeting Chungcheongnam-do direct management enterprises. To do this, this research analyzed influence with acceptability of local public enterprise management assessment by composing the area with 5 aspects related to local public enterprise management assessment. More differentiated strategy is required to operate management assessment efficiently, since direct management enterprises have different shape from other public enterprises in respect of organizational structure. In case of water and sewage, it tends to be difficult to return the result of management assessment to the local government organization, so that managers' interest and effort is necessarily required. Also, responsible person's professionalism is required to raise achievement of direct management enterprise through management assessment, politic management plan for this is necessary. Above all, the structure of incentive for management assessment result is difficult in making intended effect as other public enterprises. Therefore, differentiation of compensation system for assessment result is required.

Due to the recent aging population, the need for development and use of welfare technology is increasing in society, but the debate on the evaluation of the personal, social and economic effects of newly developed welfare technology is insufficient. The purpose of this study is to analyze the concept of welfare technology and the theoretical contents of technology assessment, and to discuss the development of indicators applicable to welfare technology assessment for older adults. For this purpose, the characteristics of welfare technologists, who are distinguished from the general technology, were examined and tried to establish the concept of welfare technology and to examine theoretically. In addition, welfare technology Assessment indicators reflect the characteristics of older adults and are presented in six areas, including personal, economic, social, technological, environmental and ethical aspects. For the case study, two welfare technology products for older adults were selected and applied to the welfare technology evaluation indicators. This study suggests that older adults and their caregivers need to be participating as an important stakeholder to increase the effectiveness of the welfare technology assessment.

Due to the importance of vehicle detector which plays an essential role in generating real-life traffic information, maintaining detector data quality is preeminent in advanced traffic management and information systems (ATMIS). To this end, agencies periodically conduct performance tests on detectors. Detector evaluation is generally performed by comparing baseline data with corresponding detector data. Here, two important things need to be addressed; one is errors (or uncertainties) included in baseline data and the other is the confidence interval concept to represent evaluation results of sample data to corresponding ones of population. To resolve these problems, a new detector evaluation scheme is introduced and the scheme is applied to individual level detector evaluations of loop, video image, and radar detectors. The purpose of individual level evaluation is to eliminate the balancing (or cancelling-out) effects of over- and under-counts. As a consequence, the proposed scheme is proven to be effectively applied to real-world detector evaluations.
