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.

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.

Cho, Eun-Sang,Choi, Kun-Ho,Kim, Min-Gyu,Lim, Hoi-Jeong,Yoon, Suk-Ja,,Kang, Byung-Cheol 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4

Purpose : This study was aimed to compare skin entrance dose of digital radiography with that of film radiography and to show the dose reduction achievement with digital systems at 11 dental schools in Korea. Materials and Methods : Forty six intraoral radiographic systems in 11 dental schools were included in this study. Digital sensors were used in 33 systems and film was used in 13 systems. Researchers and the volunteer visited 11 dental schools in Korea. Researchers asked the radiologic technician (s) at each school to set the exposure parameters and aiming the x-ray tube for the periapical view of the mandibular molar of the volunteer. The skin entrance doses were measured at the same exposure parameters and distance by the technician for each system with a dosimeter (Multi-O-Meter : Unfors instruments, Billdal, Sweden). Results : The median dose was 491.2 μGy for digital radiography and 1,205.0 μGy for film radiography. The skin entrance dose digital radiography was significantly lower than that of film radiography (p<0.05). Conclusion : Fifty-nine percent skin entrance dose reduction with digital periapical radiography was achieved over the film radiography in Korean dental schools.
