The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

This study is to follow the studies, which were conducted in Moon island between July and October in 2010. The previous studies, which were conducted by Lim, Hyun-soo and Kang Eun-suk in 2010, studied the current status of education of divers by classifying it into five subjects such as diving science, diving equipment, diving safety, underwater environment, and diving activities through FGI of expert groups. Being aware of the lack of materials about the observation of non-fulfillment of education on diving equipment and underwater environment and interviews, we made visits to the spots where the previous studies were conducted between July 28 and August 2nd to newly add up materials on interviews and questionnaires and analysed the cause and problems of the educational non-fulfillment about diving equipment and underwater environment. The educational non-fulfillment about diving equipment resulted in inappropriate management of equipment and loss of equipment, immature assembly of equipment of equipment, the loss of waist belts, and diving knife"s inappropriate use. The educational non-fulfillment about underwater environment brought about the damage of underwater environment, panic by underwater environment, conflicts with fishing villages, and the problems of trash-littering and defecation.

강은숙,최은영,공마리아 대구대학교 특수교육재활과학연구소 2008 再活科學硏究 Vol.26 No.2

본 연구는 가출청소년에게 REBT에 근거한 미술치료를 실시하여 가출청소년의 분노 경감에 효과가 있다는 것을 검증하였다. D시에 있는 가출청소년 쉼터에서 의뢰된 3명의 가출소녀에게 2007년 3월 1일부터 4월 19일까지 약 6주 동안 1주일에 2회기씩 미술치료를 실시하였다. 연구의 효과를 측정하기 위해 비합리적 신념 검사(Irrational Belief Test)를 사전 사후에 검사하여 점수를 보았고, 척도의 내용의 변화를 비교하였으며, 미술치료 회기별로 사고의 변화의 질적 분석을 하였다. 그리고 분노 경감의 효과를 측정하기 위해 분노행동인 이차적 분노사고적 언어 사용 빈도를 관찰하여 빈도 변화를 도표화하여 비교 제시 하였다. 미술치료 프로그램의 단계는 친밀감 형성과 목표 정하기, REBT이론 설명단계, 비합리적인 신념에 대한 논박 단계, 사고 탐색 단계, 문제해결 단계, 종결로 구성하여 진행하였다. 본 연구 결과는 REBT에 근거한 미술치료가 가출청소년의 분노로 인한 비합리적인 신념들을 합리적인 신념으로 바꾸는 교육과 연습을 미술 작업과 함께 함으로써 분노의 수준이 낮아지는 효과가 있음을 확인하였다. 가출청소년을 대상으로 하는 미술치료는 1회성 실시가 아니라 지속적인 프로그램 실행이 필요하고 대상에 대한 관심과 애정으로 접근하는 것이 중요하다. The purpose of this study was to investigate the effect of art therapy based on REBT that affects the anger alleviation of runaway homeless youths. The study was conducted on three girls from runaway and homeless shelter in D city, and the art therapy program was carried out weekly 2 sessions for 6 weeks from March 1 to April 19, 2007. The change of the grade was examined between the pre/post Irrational Belief Test, the changes of items in each scale were compared and the change of thought was analysed in each session to evaluate the effectiveness of the research. And for evaluation of the effectiveness of anger alleviation, the changes of frequency were presented and compared as graphs after observing secondary anger thought-verbal, which is an anger behavior. The art therapy program was composed of following steps: rapport, establishing goal, explaining REBT theory, investigation track dysfunctional schema, problem solving and a close. The conclusion of this study ascertained the fact that the art therapy based on REBT resulted in positive changes on the level of anger by applying the education and practice which change the irrational belief caused by runaway and homeless youths' anger to rational belief. It is suggested that art therapy for runaway and homeless youths has to be carried out not as an one-off performance but as a continuing program with concern and affection to them. 본 연구는 가출청소년에게 REBT에 근거한 미술치료를 실시하여 가출청소년의 분노 경감에 효과가 있다는 것을 검증하였다.

뚜렷한 입체 선택성을 갖는 알릴 디올의 고리 카보네이트와 아세토니드의 Wacker 산화 반응 연구

강석구,정경윤,정재욱,남궁은영,김태현 성균관대학교 기초과학연구소 1995 論文集 Vol.46 No.1

Palldium(Ⅱ) 촉매 하에서의 말단 알릴 디올의 고리 카보네이트와 아세토니드의 산화반응은 anti-Markovnikov hydation에 의해 알데히드 또는 α,β-불포화 알데히드 만이 생성되었다. 치환된 알릴 디올의 분자내 이중 결합의 반응으로는 (E)-알릴 디올의 경우에 β-케토 생성물을, 반면에 (Z)-알릴디올의 경우엔 α-케토 생성물을 얻을 수 있었다. 치환된 알릴 디올의 고리 카보네이트와 아세토니드에서는 각각 β-케토 화합물과 α,β-케토 화합물 들이 생성되었다. Palladium(Ⅱ)-Catalyzed oxidation of acetonides or cyclic carbonates of terminal allylic diols afforded aldehydes or α,β-unsaturated aldehydes as the sole products, resulting of anti-Markovnikov hydation. For the internal olefins of the substituted allylic diols, (E)-allylic diol provied β-keto-product, whereas (Z)-allylic diol affored α-keto-product. The acetonides and cyclic carbonates of the substituted allylic diols yielded β-keto-products and α,β-unsaturated ketones, respectively.

박현숙,장기용,김은남,강병조 대한생물치료정신의학회 1998 생물치료정신의학 Vol.4 No.2

본 연구는 선택적 세로토닌 재흡수 억제제(SSRIs), 특히 sertraline이 출혈 시간에 미치는 영향을 알아봄으로써 선택적 세로토닌 재흡수 억제제의 안전성과 혈액학적 부작용 측면을 평가하고자 하였다. 선택적 세로토닌 재흡수 억제제의 치료적 적응증에 해당하는 95명의 환자를 무작위 할당으로 sertraline 50mg 투여군, sertraline 200mg, 투여군, nortriptyline100mg 투여군, 위약(thiamine 100mg) 투여군으로 분류하여 정해진 양을 4주간 투여한 후 출혈 시간을 약물 투여 전, 약물 투여 2주 후, 약물 투여 4주 후의 3회에 걸쳐서 측정하였다. 95명의 환자 중 78명이 실험을 마쳤다. Sertraline 50mg 투여군에서 실험 전과 비교하였을 때 시간에 따르는 출혈 시간의 증가가 있었다. 다른 군에서는 실험 전과 실험 2주 후, 4주 후의 출혈 시간을 비교하였을 때 시간에 따르는 출혈 시간의 증가가 없었다. 연구 기간 동안 지혈 이상을 보인 환자는 없었다. 결론적으로 Sertraline 투여 초기에 정상 범위 내에서 출혈 시간의 증가가 있었다. Objective : This study was designed to assess the safety and hematological complications of the selective serotonin reuptake inhibitors(SSRIs) by examining the effect of sertraline on bleeding time. Method : Ninety five patients included in therapeutic indications of SSRIs were divided into sertraline 50mg, sertraline 200mg, nortriptyline 100mg, placebo(thiamine 100mg) groups. Bleeding time was measured at baseline, and repeated 2 and 4 weeks after the initiation of treatment with sertraline, nortriptyline and placebo 78 patients completed the study protocol. Result : Bleeding time was prolonged within normal range after 2 and 4 weeks of treatment in sertraline 50mg administration group. Bleeding time was not prolonged in the other groups. No patient developed clinical signs of abnormal hemostasis during the study period. Conclusion : Bleeding time was prolonged within normal range at initial period of treatment with sertraline.

김은영,양영수,강진석,김장형,최연성 제주대학교 공과대학 첨단기술연구소 2002 尖端技術硏究所論文集 Vol.13 No.2

In this paper, it was presented that broadly delivered scanner devices can also used in fingerprint recognition process and then modified existing steps of fingerprint image processing. First, using the adaptive binary method, that effect was certified already, increased the effect of the results. And then, applying table mapping methods that looks for elements from look-up table, decreased the processing time, too. Finally, it was presented that ridge-direction characteristics extracted from these processes can used effectively in the area of fingerprint recognition system.
