Field investigation was performed right after the occurrence of debris flow at Jinbu area. Geomorphic and geotechnical characteristics were investigated and rain fall data were collected. Based on these data, seepage and slope stability analysis was performed to verify the behavior of ground water and factor of safety of the slope according to the rainfall intensity and time. As a results, the minimum value of factor of safety achieved in long time after the moment of maximum precipitation rate. And it is confirmed that the factor of safety is susceptible to ground water level rather than rainfall intensity.

프로그래밍 환경이 단순구조 편집환경에서 보다 복잡한 환경으로 진보되고, 언어 기반 편집 환경의 비중이 확대되면서 속성 문법의 점진적 평가의 이용이 효과적이다. 점진적 평가는 새로운 속성 트리가 기존의 속성 트리와 정확히 비교되어 기존 속성 트리를 사용하여 새로운 속성 트리를 구성한다. 본 논문에서는 Carle의 알고리즘을 분석하고 새로운 점진적 평가 알고리즘으로 재구성한다. 특히, 새로운 속성 트리 $d'_{copy}$의 생성 과정과, 최적화된 속성트리의 새로운 점진적 평가 알고리즘을 추가한다.

This paper proposes an arc fault circuit interrupter (AFCI) using the distorted voltage wave in electric arc faults. It perceives a voltage instantaneously at the time of voltage drop. and occurrence. It is an AFCI of the new concept which operates with high reliability. The primary reason of electric fire is arc and spark. It prevents an electric fire or an electric leakage accident with quick responsiveness. Earth Leakage Circuit Breaker(ELB), Molded_case Circuit Breaker (MCCB) or Residual Current Protective Device(RCD) can not cut off electric arc or spark to be a major factor of electrical fire. This theory will be able to intercept an arc or a spark. which occurrence with periodic. Consequently It raises a reliability and validates a practicality of RCD.

본 논문은 클라이언트 버퍼 확장 기법과 프록시 프리픽스 캐싱을 응용하여 기존의 패칭 기법의 성능을 향상시키기 위한 새로운 패칭 기법을 제안한다. 제안된 기법은 프록시에서 비디오의 프리픽스를 캐싱하여 패칭 윈도우 크기를 확장한다. 또한 클라이언트의 버퍼로 부터 오버플로우된 스트림을 공유하고 저장하기 위해 프록시 버퍼를 통해 클라이언트의 버퍼 공간을 확장한다. 프록시에서 프리픽스와 패칭 윈도우 크기가 확장되므로 기존의 패칭 기법보다 서버의 대역폭 요구량이 현저히 줄어들게 된다. 성능 평가를 통해 제안된 기법이 서버의 대역폭 요구량을 줄일 수 있음을 보인다.

Carboniferous and Cretaceous rock samples were collected from 3 and 12 sites respectively in the vicinity of the Okcheon Zone. Mean directions of characteristic component magnetizations from Carboniferous rocks along the Honam Shearzone reveal that the Okcheon zone was considerably rotated and deformed during Triassic. The amount of rotations were clockwisely $80.3^{\circ}$ in Mungyeong and $42.4^{\circ}$ in Hwasun areas. Mean directions of characteristic component magnetizations obtained from Cretaceous Yeongdong and Neungju Basin were identical to those from the Gyeongsang Basin in the Yeongnam Block indicating no relative motion between them since Cretaceous. Cretaceous paleopole position from 4 locations, $204.9^{\circ}E$ in longitude and $65.1^{\circ}N $ in latitude.

This paper is study on a novel high efficiency step up-down converter using loss-less snubber capacitor. The proposed converter is accomplished that the turn-on operation of switches is on zero current switching (ZCS) by DCM. The converter is also applicable to a new quasi-resonant circuit to achieve high efficiency converter. The control switches using in the converter are operated with soft switching, that is, ZVS and ZCS by quasi-resonant method. The control switches are operated without increasing their voltage and current stresses by the soft switching technology. The result is that the switching loss is very low and the efficiency of the converter is high.

The purpose of this study was to investigate the effect of heat application on ischemia-reperfusion injury to quadriceps femoris muscle of the rats. Nine weeks old male Sprague-Dawley white rats were divided into five groups: 1) control(only reperfusion following ischemia), 2) heat application before reperfusion following ischemia(PreHeat), 3) heat application after reperfusion following ischemia(PostHeat). All groups were 30 minute, 1 hour, 3 hours reperfusion after 2 hours ischemia with clamping abdominal artery, and investigate superoxide dismutase(SOD) immunohistochemical reactions for quadriceps femoris muscle of the rat. SOD immunohistochemical reaction of experimental groups were more than the control group.

Objectives: The purpose of this study was to examine the quality and reputation of medical services in hospitals run by Gangwon-do 1,3, and 10 dentists, to investigate the mitigation effects of trust and quality on patient satisfaction and loyalty. Methods: Of the 600 surveys collected, 578 were used. Results: Although there were differences in dental services by type of institution, fame influenced patient satisfaction in all three institutions, and patient satisfaction also affected loyalty in all three institutions. The moderating effect of trust was shown to one dentist, and physician trust was shown to have a moderating effect. Conclusions: The establishment of reputation trust and the practice of dental medical services are important for attracting patients.

The reinforcement of Inorganic filler silica treated with LBR-MDI In SBR vulcanizates were Investigated. The inorganic filler silica treated with MDI on unmodified surface and that of silica treated by MDI was retreated with LBR. The charateristics of vulcanization, physical properties, surface properites and dynamic properties were investigated after mixing those silica with SBR and unmodified silica with SBR. Rheometric studies of the vulcanization showed that S-series has fast scorch $time(t_{10})$ and an optimum cure $time(t_{90})$ in the SBR compounds. And it was turned out that SBR vulcanizates compounded with LBR treated silica was better than any other componnds in hardness, tensile strenght, 100 300% modula and elongation. We could confirm that urea bonding is formed from IR spectrum. We concluded that L-series shows the best reinforcement effect in SBR vulcanizates.

Purpose: The purpose of the study was to explore the experience of patients with facial burn injuries regarding their interpersonal relationships. Methods: The phenomenological research method was used. Participants of the study consisted of five males and three females. Data were collected through individual in-depth interviews from November, 2014 to February, 2015 and analyzed using Colaizzi's method. Results: Five theme clusters were extracted that described patients' experiences. They are "being a lonely foreigner," "closing my mind toward the world," "hiding hurt feelings," "companion of my face," and "communicating with the world". Conclusion: The results of this study provide a deep understanding and insight into the experience of interpersonal relationships among facial burn patients. The development of a comprehensive program including physical, psychological, and social aspects is recommended to address the problems facial burn patients encounter in interpersonal relationships and to facilitate interaction.
