This study was aimed at analyzing the location and the characteristics of the Urban hanok tissues that were formed in the downtown since 1920s. Focusing on the relationship between roads and lots, the developing process and the typological characteristics are examined. Through dividing the large and medium lots of the aristocratic families and on the hilly area near the Seoul City Wall, various shapes of urban hanok tissue were evolved. The urban hanok tissues developed before 1936 locate on the downtown sites, while those developed after 1936 locate on the hilly sites. The location of the tissues were identified in the upper area of Jong-no street. The former is composed of small size lots divided into average area $104.4m^2$ with the narrow alleys of about 2.0m width, while the latter is composed of medium size lots divided into average area $131.54m^2$ with the alleys of about 4.0m width. Moreover the structures of the tissues were evolved based on the developing period and the site condition. Moreover the structures of the tissues were evolved based on the developing period and the site condition. The typological characteristics were defined as the four patterns categorized with the bilateral concepts of alley's form and of alley's spacial feature.

The purpose of this research presents a method to position and makes the structure for eco-corridors reasonably with collectable analysing results of various effects shown in mammals' road-kill at 429 points. Target animals of this research are Leopard cat, Siberian weasel, Raccoon dog, Korean hare, Eurasian red squirrel, Siberian chipmunk and Water deer. The results derived from the empirical analysis on the contents above are followed. First, according to the results as for Leopard cat road kill analysis, which is designated as Endangered Species Class II, the eco-corridor might be located at near village having stead food in order to decrease the frequencies of road-kill, because its road kill points were mainly collected at 4 lane hilly road with mountain-road-farm area geological type of. Second, because Siberian weasel's road kill was detected at 2 lane hilly road with mountain-road-stream geological type, the eco-corridor might be located at near a mill to decrease road-kill frequencies. Third, the road-kill frequency of Eurasian red squirrel can be reduced when the eco-corridor is located at the area across coniferous tree near 4 lane west sea freeway with mountain-road-mountain. Fourth, the road-kill of Raccoon dog can be reduced when the eco-corridor is located at 4 lane mountain road or hilly road with the geological type having farm land-road-mountain(stream). Fifth, Korean hare's road-kill can be reduced when the eco-corridor is located at grass land across ridge line of mountain, because wild rabbit road kill was happened at 4 lane mountain road or 2 lane mountain road(mountain-road-mountain). Sixth, As for Siberian chipmunk, the eco-corridor might be located at the side slope of mountain road at 2 lane mountain road under the speed of 60km/h with mountain-road-mountain. Seventh, For Water deer, the eco-corridor might be located at 4 lane hilly road with mountain-road-farm land. As for Common otter, Amur hedgehog, Yellow-throated marten, Weasel, it is difficult to specify the proper site of eco-corridor due to the lack of data. Eco-corridors for carnivores might be well located at 4 lane hilly road or 2 lane hilly road with mountain-road-farm land, and the track for herbivores might be well located as a overhead bridge on mountain-road-mountain type across mountains. In order to position eco-corridors for wildlife properly, we have to research animal's behavior with ecological background, and to consider the local uniqueness and regularly collect the empirical road-kill data in long term 3 to 5 year, which can be the foundation for the more suitable place of wild life eco-corridors.

본 연구는 수치산림입지도, 수치기후도, 제5차 국가 산림자원조사 등의 누적된 자료와 다양한 통계모형을 이용하여 기후변화에 따른 생태권역별 임상별 산림 바이오매스 변화를 예측하였다. 그 결과 시간 경과에 따른 산림 바이오매스 변화량은 생태권역별 임상별로 서로 다른 패턴을 보였다. 산악권역, 남동산야권역, 남서산야권역에서는 시간이 경과함에 따라 모든 임상에서 산림 바이오매스가 감소하는 것으로 예측되었다. 반면에 중부산야권역의 침엽수림과 혼효림은 기후변화의 영향으로 바이오매스가 증가하는 것으로 분석되었다. 또한 해안도서권역에서는 침엽수림을 제외한 임상에서 산림 바이오매스가 증가하는 것으로 추정되었다. 본 연구는 기후변화 시나리오에 따른 지위지수 추정치 변화에 근거하여 산림 바이오매스 변화량을 산출함으로써 기후변화에 따른 산림재해 변화 패턴을 예측할 수 있는 정보를 마련하였다. 본 연구의 결과는 산림재해 대응전략 수립에 필요한 정보로 활용될 수 있을 것으로 기대된다.

This study was carried out to evaluate the analysis of environmental change (forest resources and soil water conservation by land types) after planting for prevention of between 2003 and 2006 from the stone hazarding areas in Guizhou province, China. Mean diameter growth of the trees was highest for Melia azedarach, followed by Robinia pseudoacacia, Lonicera fulvotomentosa, Choerospondias axillaris, Cupressus duclouxiana, and Eucommia uimoides Oliv. Mean height growth of the trees was greatest for R. pseudoacacia, followed by Ilex kudincha, M. azedarach, C. duclouxiana, C. axillaris, E. uimoides Oliv, Zanthoxylum bungeanum, and L. fulvotomentosa. Tree biomass was greater at the afforestation sites by 1.22-1.71 ton/ha compared to that of severely eroded mountain areas. The capacities of soil water conservation by land types were 2,790 ton/ha at latent rock desertification farmland, 2,655 ton/ha at rock desertification farmland, 1,680 ton/ha at dolomite sandstone hilly country, 1,650 ton/ha at halfstony hilly country, and 1,590 ton/ha at karst physiognomy site. Soil erosion was estimated to be 1,285 ton/$km^2$ which had been 2,178 ton/$km^2$ before afforestation. Also, we should be continuative manage after planting for prevention of the stone hazarding areas in Guizhou province, China.

2001년 9월부터 2002년 6월까지 소규모 집수역 내 고도가 다른 3개 지점(해발 49, 104, 253m)에서 30분 간격으로 기온을 측정하여 다음과 같은 결과를 얻었다. 평균기온은 100m 당 0.2$^{\circ}C$씩 하강하였으며, 이 감율양상은 낮 시간대 지형에 의한 일사 수광량 변이에 의해 증폭되었다. 그러나 감율양상은 일몰시점부터 고도가 높을수록 기온이 더 높아지는 역전양상으로 전환되어 다음 날 일출시점까지 지속되었다. 이에 따라 계곡기저의 일 최저기온이 253m 지점에 비해 더 낮은 날이 연중 67%를 차지하였고 연평균 기온편차는 1.4$^{\circ}C$ 이었다. 맑은 날의 최저기온 역전강도는 겨울보다 봄가을에 더 커지며 대상지역에서 관측된 최대값은 6$^{\circ}C$ 이었다. 흐리고 비온 날의 최저기온은 감율양상이 지속되었으며 봄가을보다 겨울철의 기온감율이 더 컸다.

Eight hundred and seventy on goats from Naikhongchari FSR site in Bandarban district were examined for gastro-intestinal nematodes. The parasites encountered in the region were Haemonchus Sp, Bunostomum Sp, Oesophagostomum Sp and Strongyloides Sp. The overall infection rate was 78.41%. Among various species found. Haemonchus Sp emerged as the most prevalent, although Oesophagostomum and Bunostomum were also found in this studies. The seasonal fluctuation in infection was assessed by monitoring the fecal egg count. The maximum values for the prevalence and overall mean EPG were observed after the heavy rain fall season and remained at a relatively high level from June to November. Haemonchus Sp and Oesophagostomum Sp appeared to be of major important parasites in the goats of this climatic zone which deserved proper treatment to attain higher production from goat.

This paper concerns the design of blasts adjacent to structures and facilities. In order to investigate the site characteristics, measurements of in-situ wave propagation and laboratory tests of rock cores taken from the boreholes were carried out. Effects of rock media and delay intervals on ground vibration levels were identified from over sixty measurements of three times of test blasts. For practical use in the field, an empirical propagation equation was derived so as to reflect the characteristics of rock media and delay effects. Safe limits of vibration level for structures were conservatively established based on various suggested criteria. Safe limits for facilities were adopted so that vibration levels induced by blasting should not exceed the allowable limits specified in the manufacturer's installation condition. Suggested were blast pattern and operation to enhance the rock fracturing and to reduce the ground vibration levels under the restricted conditions.

본 연구에서는 KoFlux네트워크 타워 관측소의 하나인 광릉 낙엽 활엽수림에서 최초로 직접 관측된 이산화탄소 플럭스를 보고한다. 2002년 6월부터 8월까지 에디 공분산 시스템을 다른 기상 관측 기기들과 함께 30 m 타워에 설치하였다. 관측 장소가 계곡과 같은 경사지에 위치해 있음에도 불구하고 관측된 난류 특성이, 제한된 풍향(즉, 90$\pm$45$^{\circ}$)의 경우, 평평하고 균질한 이상적인 장소에서 관측된 것들과 크게 다르지 않았다. 관측 자료 회수율은 비록 낮았으나, 분석된 예비 결과는 고무적이고, 연구해야 할 가치가 있는 것으로 나타났다. 이류 항을 무시하면, 생태계의 순 $CO_2$ 교환(NEE)은 6월에서 8월까지 약 -1.2에서 0.7 mg m$^{-2}$ s$^{-1}$의 범위를 보였다. 약한 난류가 야간 NEE에 미치는 효과를 마찰 속도(u*)및 저류 항의 산출과 관련하여 살펴보았다. 낮은 u*가 NEE에 미치는 영향은 약 0.2 m s$^{-1}$의 문턱 값을 기점으로 뚜렷하게 나타났다. 야간 NEE에 미치는 저류 항의 역할은 거의 나타나지 않았는데, 이는 밤 동안 산림 내에 축적된 $CO_2$가 경사면을 따라 배수류로 빠져나갔기 때문인 것으로 사료된다. 이는 또한 저류 항을 한 높이에서만 관측된 농도 자료를 사용함으로 생긴 오차로 인한 인위적인 결과일 수도 있다. 쌍곡선 광 반응식을 적용한 결과, 관측된 NEE 변화의 80% 이상이 설명되어, 이 산림 지역의 $CO_2$ 교환이 주로 빛에 의해 조절됨을 보여주었다. 이러한 관계식은 계절에 걸쳐 빠진 자료를 채워 넣는 자료 처리 과정에 효과적으로 사용될 수 있다. 마지막으로, 선형류 모형에 근거한 간단한 규모 분석에 의하면, 이류항의 효과가 NEE산출에 큰 영향을 미칠 수 있는 것으로 나타났다.
