As high-rise buildings came in, the landscape of rural areas and natural landscapes often got damaged. Therefore, this study aims to prevent this, grasp the extent of the influence of the surrounding landscape, to grasp the range of height that can be permitted and present the direction of landscape management of agriculture and natural landscape. This study tried to grasp the range of height by using price sensitivity analysis method for two apartment and apartment complex which entered DangJin city and SeoSan city. First, in the case of a two apartment, the range of the height allowable section was from the 6th floor to the 11th floor in close range view, and it was a section from the 7th floor to the 12th floor in medium range view. In the case of the apartment complex, the range of the height allowable range was from the 10th floor to the 17th floor in close range view, the 9th floor to the 16th floor in medium range view. The stress index was found to be positive in a two apartment in close range view, and in the apartment complex case. therefore it was better to set it to a lower in the Range of Acceptable Height(RAH). Second, it showed no difference in the sensitivity of landscape to gender. Thirdly, the results of the landscape sensitivity analysis of major and non-major showed the difference in the medium range view picture of the apartment complex. Majors are lower than the point of minimum height(PMinH) than non-Majors. In the case of major, the stress index was 1.4. it turned out that it was better to make a decision closer to point of minimum height (PMinH). In the case of non-major, the stress index was -1.3. it was also able to accept decision close to the point of maximum height (PMaxH). Since the results of the above research gave changes only in the variable of the height of the landscape, we can not grasp the point of interaction with other variables, and future research is considered necessary.

Malignant esophagorespiratory fistula is a devastating and life-threatening complication of esophageal and bronchogenic carcinomas. As a non-surgical treatment, peroral stent placement into the esophagus or airway can close-off the fistula and prevent progression of the pneumonia. Although reopening of the fistula is not uncommon despite stent placement, interventional treatment is effective for sealing off reopened ERFs. Bronchopleural fistula is a well-recognized complication of pneumonectomy. There have been several reports to occlude the fistula with use of stents and much more experience is required.

목적: 골수강 내 금속정을 이용한 경골 분절 골절 치료에서 다양한 술식을 이용한 임상적 결과에 대해 알아보았다. 대상 및 방법: 2003년 1월부터 2009년 6월까지 경골 분절 골절 환자 중 골수강 내 금속정을 이용하여 수술 후 1년 이상 추시 가능한 18예를 대상으로 하였다. 평균 추시 기간은 38개월(15-72개월)이었다. 골절 분류는 AO 분류 42C2.1 4예, 42C2.2 10예, 42C2.34예였다. 폐쇄성 골절이 10예, 개방성 골절은 8예였다. 수술 시 정복을 위한 다양한 술식을 이용하였고, 골유합 시기와 불유합 또는 부정유합 등의 합병증을 조사하였다. 결과: 지연유합으로 뼈이식이 필요한 경우가 3예였으나, 추후 전 예에서 골유합을 얻었다. 평균 골유합 기간은 16.3주(범위 12-21주)였다. 5도 이상의 각형성은 2예에서만 나타났고 평균 각변형 정도는 2.2°였다. 슬관절 운동범위는 129°, 족관절의 운동범위는 68°였으며 관절의 구축이나 25° 이상의 운동 범위의 감소는 관찰되지 않았다. 다른 합병증은 국소감염증 2예가 있었다. 결론: 금속정 삽입 시 부가적인 술식의 사용이 동반되면 경골 분절 골절에서 교합성 골수강 내 금속정을 이용한 치료는 높은 골유합률과 낮은 합병증, 만족할 정렬을 얻을 수 있을 것으로 생각된다. Purpose: We evaluated the clinical outcomes of tibia segmental fractures treated by intramedullary nailing using various reduction techniques. Materials and Methods: From January 2003 to June 2009, 18 segmental tibial fracture patients treated by intramedullary nail were enrolled with a minimum 12-month follow-up. The mean follow-up was 38 months (range 15-72). According to the AO classification, the fractures were types 42C2.1, 42C2.2, and 42C2.3 in four, ten, and four patients, respectively. Ten fractures were closed and eight were open. We used various techniques for reduction during operation and investigated bone union time and complication (non-union, malunion etc.). Results: Bone grafting was performed in three patients. Complete union was achieved in all patients. The mean time for union was 16.3 weeks (range 12-21), except in three delayed union patients. All radiological evaluations showed good alignment (less than 5 degree) except in two patients; and the mean deformity angle was 2.2 degree. Knee range of motion (ROM) was 129 degree, and ankle ROM was 68 degree. Local wound infection occurred in two patients. Conclusion: Intramedullary nailing is a successful method in the acute management of segmental tibial fractures, if accompanied by appropriate reduction technique.

본 연구는 도시가로가 도시이미지를 결정짓는 중요한 요소이며, 도시가로 중 상업가로는 지역경제 활성화와 시민 삶의 질 향상 측면에서 중요한 의의가 있으나, 급속한 경제 발전과 산업화로 무분별하고 무질서한 개발을 이룬 구도심 경관이 질적 저하가 이루어진 문제점은 찾고자 진행되었다. 이를 위해 구도심 상업지역인 천안시 역사 주변의 상업 가로경관을 중심으로 이미지 현황을 형용사 어휘로 분석하였다. 분석 결과, 구도심 상업지역의 가로경관은 가로와 가로지역의 건축물, 가로의 오픈스페이스로 구분되어 가로의 경우에는 현대성, 복잡성, 질서성으로 설명되어지며, 가로지역의 건축물 외관은 질서성, 활동성, 정돈성, 복잡성으로 설명되어진다. 가로의 오픈스페이스의 경우에는 질서성, 쾌적성, 복잡성으로 설명되어진다. 연구결과를 통해 복잡성과 질서성의 이미지가 상업가로가 설명되는 주요 인자로 판단되었으며, 각 유형에 맞는 차별화된 가로경관 이미지를 구축하는 근거자료로 활용할 수 있을 것이다. Urban street is an element to determine an urban image and especially, commercial street is important for revitalizing local economy and improving the quality of citizen life. However, the rapid economic development and industrialization has brought a qualitative decline in the landscapes of old downtowns, due to the ill-advised and disordered development. Therefore, this study was conducted to find the problems of the qualitative decline. For this study, the present images of commercial street landscapes around the Cheon-an City Station, where is an old downtown commercial area, was analyzed using landscape adjectives. As a result, the street landscapes of old downtown commercial area were divided into a street, a building of street area and an open space of street. Here, street is explained as modernity, complexity and orderness, and the exterior of building in street area is explained as orderness, activity, orderliness and complexity. Also, open space of street is explained as orderness, comfortableness and complexity, In conclusion, the image of complexity and order ness were found as major factors of commercial street, and this study would be able to serve as basic data for constructing differentiated street landscape images.

ABA형태의 삼중블록공중합체는 고무상과 유리상의 상대적 성분에 좌우되는 열가소성 탄성체와 강화 플라스틱으로써 유용하다. 이러한 물질은 다른 고분자와 혼합하여 첨가제, 강화제, 상용화제로써 기능성을 줄 수 있다. 상업적으로 유용한 대부분의 블록 공중합체는 석유로부터 유래된다. 지구상의 유한한 화석자원 공급과 석유 사용 및 채굴에 관련된 경제, 환경적 비용을 고려하면 그 대안은 매력적이다. 이러한 흐름에 더하여 미래 지속 가능한 물질의 최종 용도를 위한 설계 및 그 실행이 요구되고 있다. 본 총설에서는 재생 가능한 ABA 형태의 삼중블록 공중합체 합성과 특성을 살펴보고, 특히 공중합체의 경성부분을 위한 높은 유리 전이온도 혹은 녹는점을 지닌 식물 유래 폴리올레핀과 다당류 유래 폴리락타이드와 공중합체의 연성부분을 위한 바이오 기반, 낮은 유리 전이온도, 무결정의 탄화수소계 고분자에 대해 논의하려고 한다. 이를 위해서 다양하게 제어된 고분자 중합법은 강력한 도구임이 증명되고 있다. 이러한 혼성 고분자의 정교한 합성에 관한 연구는 재생가능성, 생분해성, 고성능을 지닌 새로운 탄성체와 강화 플라스틱의 발전을 이끌고 있다. Block copolymers including ABA triblock architectures are useful as thermoplastic elastomers and toughened plastics depend-ing on the relative glassy and rubbery content. These materials can be blended with other polymers and utilized as additives, toughening agents, and compatibilizers. Most of commercially available block copolymers are derived from petroleum. Renewable alternatives are attractive considering the finite supply of fossil resources on earth and the overall economic and environmental expenses involved in the recovery and use of oil. Furthermore, tomorrow`s sustainable materials are demanding the design and implementation with programmed end-of-life. The present review focuses on the preparation and evaluation of new classes of renewable ABA triblock copolymers and also emphasizes on the use of carbohydrate-derived poly(lactide) or plant-based poly(olefins) having a high glass transition temperature and/or high melting temperature for the hard phase in addition to the use of bio-based amorphous hydrocarbon polymers with a low glass transition temperature for the soft components. The combination of multiple controlled polymerizations has proven to be a powerful approach. Precision-con-trolled synthesis of these hybrid macromolecules has led to the development of new elastomers and tough plastics offering renewability, biodegradability, and high performance.

The economic feasibility of a commercial indirect liquefaction process with the co-gasification process of petroleum coke which has been recognized as hazardous waste because of high sulfur content and bituminous coal and sub-bituminous coal mixtures was assessed. The 2,000 ton/day scale indirect liquefaction process including co-gasification, clean up, Fischer-Tropsch conversion and so on was assumed and used to analyze economical efficiencies with various conditions. Financial data from previous studies were modified and used and economical sensitivities with various mixture ratios were evaluated in this study. As a result, economic values of petroleum coke were superior than those of coals because of increasing sulfur sale. Also, mixtures with petroleum coke and bituminous coal was more favorable that those with petroleum coke and sub-bituminous coal due to lower moisture content. In case of sub-bituminous coal, the mixture ratio with petroleum coke had to be over 40wt% for the IRR of mixture to surpass 10%.

Disease is the major problem in ginseng cultivation from seed stratification, soil preparation prior to planting, right through to drying of the roots. There are many soil-borne disease pathogen in rhizosphere soil environment, furthermore occurrence of diseases by a diverse group of fungi and related organisms are closely related to various soil condition. Observable symptoms for soil-borne diseases include wilting, leaf death and leaf fall, death of branches and limbs and in severe cases death of the whole plant. The fungus Cylindrocarpon destructans is the cause of root rot characterized by a decay of the true root system in many ginseng production areas in Korea. Some pathogens are generally confined to the juvenile roots whilst others are capable of attacking older parts of the root system. However, the relation between the soil environmental characteristics and ginseng root rot by soil-borne disease pathogen is not clearly identified in ginseng field. In this paper, we reviewed soil-borne plant pathogen causing root rot disease of ginseng with respect to soil environment.
