Comparative analysis of forest fire danger rating on the forest characteristics of thinning area and non-thinning area on forest fire burnt area was studied in this work. To investigate the effect of thinning slash in forest fire, Gangneung-si Wangsan-myeon, Ulgin-gun Wonnam-Myeon, Samchok-si Gagok-Myeon, in which forest fire broke out, were selected. As a result that investigated forest fire danger ratio between thinning slash and non-thinning slash, leeward scorching ratio(36%), crown damage ratio(29%), mortality of branch at the former are higher than those at the latter, leeward scorching ratio of tree, where thinning slash is around, is 10%-20% higher than that of independent tree. So I estimate that thinning slash has a some effect on the intensity of forest fire. And the result to investigate damage of forest fire according to tree species shows that leeward scorching ratio of conifer is 5% higher than that of non-conifer, and mortality of branch of the former is 19% higher than that of the latter. It is considered that forest fire may affect directly to a tree trunk if it diffuse to piled thinning tree because there was no space between thinning trees and trees. Furthermore, it was found that re-ignition had a chance to occur due to lots of piled thinning trees.

Nowaday, for the promotion of producing forest trees, production of excellent timbers, and build-up of public forest area, it is on the increase of the thinning-forest for artificial forest, natural forest, eco-friendly forest, and the forest for development and improvement of forest resources nationwide. Even though the thinning-forest is applied around 180,000ha every year, the quantity of collected/used products is only 18,000ha <TEX>$(240,000m^3)$</TEX> which is 10% of the whole thinning-forest area. Meanwhile, some reports represent that the left products after thinning-forest might increase the severity of forest fire and the waste of resources. Therefore, this study focused on the analysis of correlation between the accumulated products after thinning-forest and forest fire, and providing a preparation plan for the forest fire.

대학도서관 사서의 위기와 대처

이시영,Lee, Si-Young 한국도서관정보학회 2010 한국도서관정보학회지 Vol.41 No.3

오늘날 대학도서관 사서는 변화된 환경적 요인에 의해 전문직으로서의 그 직업적 정체성과 안정성을 위협받고 있다. 따라서 대학도서관 사서는 시시각각으로 변화하는 정보환경과 교육환경에 신속하게 적응하고 이용행태 변화에 따른 정보욕구를 충족시키기 위해 역할을 변화시킴으로써 그 존재 가치를 상승시킬 수 있을 것이며 그동안 지켜온 사서로서의 정체성을 유지할 것으로 생각된다. 이에 본 연구는 대학도서관 사서의 전문직으로서의 직업적 정체성을 위협하는 요소가 무엇인지를 현상과 문헌을 통해 파악하고 안정된 환경에서 전문가로서의 자부심을 가질 수 있도록 여건을 조성하기 위한 대처방안을 모색해 보고자 한다. These days, librarians working at university libraries have been suffering from uncertainty about their professional identity and their position stability by ever-changing circumstances. Therefore, librarians at university libraries have to adapt quickly to the informational and educational environment which are constantly changing. They have to alter their role to meet information needs of users and only then can boost their value to maintain their longstanding identity as an expert on information storage and access. The purpose of this study is to find factors which threaten the professional identity of librarians working at university libraries by analyzing the literature and phenomena and to research an effective counterplan to create conditions for librarians to take pride as professionals in stable circumstances.

이시영,박흥석,Lee,Si-Young,Park,Houng-Sek 한국방재학회 2008 한국방재학회 학술발표대회논문집 Vol.2008 No.1

We studied a basic concept and application about FARSITE, which is a forest fire spread simulator for preventing and predicting fire in United States Department of Agriculture(USDA). And, we researched a problem in the transition for introducing, so we serve the basic method for prevention and attacking fire. For this transition, we compared the behavior of the 2005 Yangyang forest fire with the result of a simulation. The spread direction is similar to real data. But, while mean spread of rate was 0.65km/hr on real data, it was 0.3km/hr on simulation. As Damaged area is 1,387ha on real, it was 5,368ha on simulation. Therefore, it is necessary to establish a fuel concept for more accurate simulation.

본 연구는 1945년부터 2010년 까지 우리나라 주요 산불정책 변화 분석과 향후 정책대안을 마련하기 위하여 광복이후 산림청 발족 이전(1945~1966), 산림청 발족 이후 산림기본계획 수립이전(1967~1972), 제1차 산림기본계획기(1973~1978), 제2차 산림기본계획기(1979~1987), 제3차 산림기본계획기(1988~1997), 제4차 산림기본계획기(1998~2007), 제5차 산림기본계획기(2008~현재) 등 7단계로 나누어 분석한 결과, 1996년 4월 강원 고성산불을 계기로 산불조직, 제도 및 기술의 발전을 가져왔으며, 향후에는 보다 체계적인 지역단위 산불대응체계의 정착과 훈련이 필요하다. In this study, we studied and analyzed the change of forest fire policies in order for helping to improve a established forest fire policies. We divided into 7 periods for easier analysis. The first period was `the period of pre-establishing the Korea forest service after independence (1945-1966). And the second was `the period of pre-basic plan of forest` after establishing the Korea forest service(1967-1972). The third was `the period of the first basic plan of forest`(1973-1978). The forth was `the period of the second basic plan of forest`(1979-1987). The fifth was `the period of the third basic plan of forest`(1988-1997). The sixth was `the period of the forth basic plan of forest`(1998-2007). And the seventh was `the period of the fifth basic plan of forest`(2008-present). In the result, the fire fighting organization, system and techniques was made rapid progress after Goseong forest fire in Kangwon region in April 1996. For future large scale forest fire attacking, the establishment of more systematical regional forest fire action plan and exercise from this would be needed.

이시영,안상현,Lee,Si-Young,An,Sang-Hyun 한국방재학회 2008 한국방재학회 학술발표대회논문집 Vol.2008 No.1

This study analyzed on the area of Samcheok, Kangwondo about forest fire alarming area and enlargement of the area. Then, visible area by unattended watching camera and watchtower for forest fire which were run by Samcheok was cross-checked with geographic information system, and it could be whether effective on watching the area where the forest fire risk was high enough and also it could be expanded to larger forest fire. The result of study, the visible area by watching facilities only holds for 13.4% of the whole forest fire alarming area, but the forest fire can be observed even though it is occurred in small valley because of smoke and all the forest fire have been occurred in daytime. Therefore, it can be determined that watching area will be extended around 50.3% while the observation radii of watching facilities raise by 4km. However, Samcheok has much greater area of mountain area in compared to any other cities or counties, watching facilities should be installed and run additionally for extinguishing the forest fire from the beginning.

이시영,김지은,Lee. Si-Young,Kim. Ji-Eun 한국방재학회 2011 한국방재학회논문집 Vol.11 No.1

봄철은 강수량이 연평균의 13% 정도로 적어 건조한 계절이며, 영동지역에 대형 산불이 많이 발생했던 해는 풍속은 강하고 공중습도가 봄철 평균보다도 낮고 강수량도 상대적으로 적어 더욱 건조했다. 대형산불이 발생했던 날은 평균풍속, 최대풍속, 최대순간풍속이 5.9 m/s, 11.3 m/s, 20.9 m/s로 산불 발생일의 평균값보다 1.8 m/s, 3.0 m/s, 6.9 m/s 크게 나타나, 산불의 대형화와 기상요소는 밀접한 관계를 나타냈다. In this study, we analyzed the meteorological elements, when large forest fires were occurred, The rate of precipitation was 13% of annual average precipitation. Especially, the stronger wind speed, lower humidity and rainfall than average annual record were the distinct feathers on the year when large forest fire occurred in east coast area in Kangwon region. The average, maximum and maximum instantaneous wind speed was 5.9 m/s, 11.3 m/s and 20.9 m/s when large forest fires occurred. The average, maximum and maximum instantaneous wind speed on large fire occurred were 1.8 m/s, 3.0 m/s and 6.9 m/s faster than and average wind speed when whole forest fires occurred. The results indicated that the large forest fire occurrence had a close correlation with meteorological elements.

이시영(Si-young Lee),김학주(Hark-joo Kim),전희(Hee Chun),염성현(Sung-hyun Yum),이현주(Hyun-joo Lee) (사)한국생물환경조절학회 2007 생물환경조절학회지 Vol.16 No.2

겨울철 난방연료가 많이 소모되는 대규모 연동형 온실의 보온성을 향상시키기 위해 터널용 보온자재로 많이 사용되는 다겹보온커튼을 이용하여 기존의 부직포, 알루미늄스크린 등과 보온성을 상대적으로 비교하였다. 또한 다겹보온자재는 보온성이 높으나 두께가 두꺼워 전동모터를 이용한 자동개폐장치를 구성하기 어려운 단점이 있으므로 연동형 온실에 적용할 수 있는 고장이 적고 작동이 원활한 커튼 개폐장치를 개발하여 작물재배 및 난방연료 절감효과를 검토하였다. 다겹보온자재와 부직포, 알루미늄스크린 등의 보온커튼용 자재의 열관류량을 측정하여 상대적인 보온효과를 비교한 결과 부직포에 비해 알루미늄스크린의 열관류량이 적었고, 알루미늄 및 화학솜의 3겹보온자재와 다겹보온자재는 알루미늄스크린에 비해 열관류량이 각각 23.3%, 43.0% 적게 나타나 다겹보온자재의 보온성이 우수한 것으로 판단되었다. 다겹보온자재는 여러 겹으로 누빈 조합형 보온자재이므로 두께가 두껍고 화학솜, 폴리폼 등 연신되기 쉬운 자재를 이용하므로 장기간 사용시 커튼 개폐장치의 예인선이냐 보온자재가 처지게 될 우려가 있으므로 예인식과 권취식 개폐방법을 동시에 적용하여 보온커튼 개폐장치를 구성하였다. 시험용 온실에 다겹보온커튼과 부직포커튼을 설치하고 풋고추를 재배한 결과 다겹보온커튼 설치 온실에서 풋고추의 생육이 유리하였고 초기수량도 27% 정도 증수되었으며, 경유온풍기의 난방연료 소모량은 46% 정도 절감되었다. This study was accomplished to compare energy saving effects of several heat insulation materials in greenhouse and to develop new automatic opening and closing equipment which is suitable to the most effective heat insulation material. To find out more effective heat insulation material, the magnitude of heat transfer occurred through aluminum screen (ALS), non-woven fabric (NWF), double-layer aluminum screen with chemical cotton sheet (DAL), and multi-layer fabric screen material quilted with non-woven fabric, chemical cotton, poly foam, and polypropylene (MLF) were compared relatively. The results showed that the relative magnitude of heat transfer occurred through MLF was lower than DAL and ALS by 23.3% and 43.0% respectively. MLF screen material was the most effective compared with other heat insulation materials. But because of thickness, there was a need of new mechanism for automatic operation in greenhouse. Accordingly, new screen system using MLF-thick but profitable for keeping warm in greenhouse-was developed. Opening & closing equipment was designed to roll MLF with pipe axis during opening process and pull MLF with string during closing process with electric motors, clutches, drums, and so on. In hot pepper cultivation and energy saving test during winter time, the early stage yield of pepper under MLF screen system was higher than NWF by 27%, and gasoline consumption of MLF screen system was lower than NWF by 46%.

Forest fire danger rate of thinning area was lower than that of non thinning area, because height rate of leewardside in burned stem of tree, damage rate of crown and mortality of tree in thinning area were 30.8%, 37% and 48.4% lower than that in non-thinning area, respectively. Intensity of forest fire varied depending upon topographical condition up slope, down slope, aspect, location as well as species, breast height diameter and forest tree density. Especially, a mountaintop area was burned down when forest fire was spread to up slope ridge of mountain.
