Delamination crack detection is very important for improving the structural reliability of laminated composite structures. This requires real-time delamination detection technologies. For composite laminates that are reinforced with carbon fiber, an electrical potential method uses carbon fiber for reinforcements and sensors at the same time. The use of carbon fiber for sensors does not need to consider the strength reduction of smart structures induced by imbedding sensors into the structures. With carbon fiber reinforced (CF/) epoxy matrix composites, it had been proved that the delamination crack was detected experimentally. In the present study, therefore, similar experiments were conducted to prove the applicability of the method for delamination crack detection of CF/polyetherethereketone matrix composite laminates. Mode I and mode II delamination tests with artificial cracks were conducted, and three point bending tests without artificial cracks were conducted. This study experimentally proves the applicability of the method for detection of delamination cracks. CF/polyetherethereketone material has strong electric resistance anisotropy. For CF/polyetherethereketone matrix composites, a carbon fiber network is constructed, and the network is broken by propagation of delamination cracks. This causes a change in the electric resistance of CF/polyetherethereketone matrix composites. Using three point bending specimens, delamination cracks generated without artificial initial cracks is proved to be detectable using the electric potential method: This method successfully detected delamination cracks.

결론적으로 위성에 의한 강우관측은 지금은 지구의 거의 대부분 지역에서 관측 및 모니터링과 더불어 강우를 이해하는 능력에 커다란 기여를 하고 있다. 특히 1997년 11월 TRMM의 등장으로 강우의 연직분포 및 정량적 관측이 이루어지므로서 국내에서도 위성강우의 활용연구가 급진전할 것으로 기대된다. 또한 위성강우자료를 이용한 농업 및 수자원분야에서의 연구도 기대된다. 위성강우자료를 농업/수자원 분야에 적용하기 위해서는 먼저 자료간의 결합시에 발생되는 규모(scale)와 해상도(resolution) 문제를 다루는 평가연구가 요구된다. 규모문제는 주어진 연구에 가장 적절한 구역의 개수에 대한 불확실성 때문에 발생되며, 해상도 문제는 해당자료를 저해상으로 결합하여 분석하게 되면 기대치 이상의 정보손실을 야기시키기 때문이다. 이와 같은 의문점이 어느 정도 구명된다면 위성강우자료를 이용한 연계연구는 무궁무진하다고 말할 수 있다. 예를 들면 농업분야에서는 위성강우에 의한 격자기반(grid-based)의 토양수분 및 지하수위 변화, 농경지 침수지역 예측 등에, 수자원분야에서는 공간강우-유출해석에 의한 홍수예 · 경보시스템의 향상, 도시지역 홍수범람지역의 예측 등에 활용할 수 있다.

Purpose: The purpose of this study was to develop a standardized education protocol for peritoneal dialysis patients. Methods: First, the demand for education was investigated from the 27 patients on peritoneal dialysis and 16 guardians, and later, the standardized nursing education protocol has been developed through the comprehensive literature review and the critical analysis of the related studies. Contents validity and applicability have been tested through the expert group survey. Results: The standardized peritoneal dialysis nursing education protocol with 9 areas and 20 items has been developed. The content validity for timing and duration, contents, method, and place of education proposed by the protocol were all above than 0.8. In terms of the applicability of the protocol, the experts scored between 4.20 to 4.93 for all items except one. The item on home visit education acquired the lowest applicability score, because there might exist potential restrictions in visiting patient's home. Conclusion: The standardized education protocol developed in this study turned out to be adequate by representing high content validity for all items and the applicability also was high except the item on home visit education. Further researches to test the effects of this education protocol should be done.

The purpose of the study is to identify Ambulatory Care Sensitive Conditions (ACSC) and their potential health insurance applicability in Korea, using the correlation and regression analysis with the empirical data provided by Korean Health Insurance Review Agency(KHIRA). Here, ACSC would be thought of as conditions that when timely and effectively treated in the outpatient medical services can help reduce the risk of hospitalizations. As for ACSC, reducing accessibility for outpatient visit results in increasing hospitalization. In this respect, the ACSC concept is popularly adopted as one of the performance indicators of the national health system. As one of main results, fortifying the accessibility to necessary health care in a way of sharing appropriately the role with private health insurance can lead to the efficiency of national health care delivery systems in view of total health care expense, in particular in a case of ACSC children. Lastly, we would like to strongly suggest that the disease treatment data set reported to KHIRA needs to be opened to private insurance companies only for illness experience investigation.

As impermeable layer continues to increase with the urbanization process, direct input of nonpoint source pollutants into water bodies via stormwater has caused serious effects on the aquatic ecosystem. Potential applications of rain gardens are increasing not only as best management practices (BMP) for reducing the level of nonpoint source pollutants but also as an ecological engineering alternative for low impact development (LID). In this study, remediation performance of various planting types, such as a mixed planting system with shrubs and herbaceous plants, was assessed quantitatively to effectively manage stormwater and increase landscape applicability. The mixed planting system with Rhododendron lateritium and Zoysia japonica showed the highest removal performance of $76.9{\pm}7.6%$ and $58.4{\pm}5.0%$ for total nitrogen and $89.9{\pm}7.9%$ and $82.4{\pm}5.2%$ for total phosphorus at rainfall intensities of 2.5 mm/h and 5.0 mm/h, respectively. The mixed planting system also showed the highest removal performance for heavy metals. The results suggest that a rain garden with the mixed planting system has high potential applicability as a natural reduction system for nonpoint source pollutants in order to manage stormwater with low concentrations of pollutants and will increase water recycling in urban areas.

This study was attempted to provide a scientific basis for the problem of location selection by spatial scale for efficient promotion of projects related to green care farm complex. Location potential assessment system in local government scale consists of two major components from demand-side and supply-side consideration. The demand-side aspect considered the characteristics of potential users, while supply-side aspect used total 18 indices over 8 divisions under 3 fields. For the location potential assessment in district scale, total 8 indices under 3 major divisions were considered based on biological, physical, social, and economic environment. The application results of the location potential evaluation system in local government scale(excluding metropolitan cities) showed high location potential in southern Gyeonggi Province and near Busan Metropolitan City. As a result of applying the district-scale location potential evaluation system to Geumsan-gun, Geumsan-eup, Chubu-myeon, and Jewon-myeon have high potential. Further studies to improve the applicability of the developed indices are recommended by enhancing assessment indices, complementing base data, and reinforcing with spatial analysis.
