The growing condition and the point at issue were investigated for utilization as a fundamental data of the Boxthorn research in the growing farm household, which was chief producing district of Box-thorn in Chongyang, Chungmam province. The results were summarized as follow'; Lycium fruit wasproduced 445M/. in the 170.4ha. In practical cultivation, major numbers of decapitation were threetimes,, and planting distance was dense planting, and also amount of applied fertilizer was beyondbasic-fertilizer level and number of split application was abundant.Numbers of harvesting were six-ten times, and many labor was requiremented.The issues in cultivation were development of processing technique, supplement of varieties whichhave disease tolerance, superior quality and high yielding, improving of cultivation methods for laborsaving and magnification of demand.

경사 영상을 사용하는 워터쉐드에서는 영상 내의 잡음이 직접 국부적 최소 점들로 표현되어 영상의 과분할을 초래하게 된다. 특히 분할되어야 할 영역들의 경계에 대한 기울기 크기는 영역 분할의 정확성에 영향을 주어 전체 분할 성능을 좌우할 수 있다. 그러므로 본 논문에서는 기울기 크기를 결정하기 전에 영역들에 대한 경계의 선명도를 보존하면서 잡음을 제거함으로써 영상의 과분할을 줄일 수 있는 ATMF(Adaptive Trimmed Mean Filter)의 적용을 제안하였다.

Rice Fields have provided large areas of open water for centuries in regions with a variety of rice-growing cultures, and, in addition to producing rice also provide other animal and/or plant food sources and medicinal plants, thus acting as wetland systems and helping to sustain livelihoods and human well-being in these regions. Also rice fields in many parts of the world support important wetland biodiversity, such as reptiles, amphibians, fish, crustacean, insects and mollusca, and play a significant ole in water-bird flyways and the conservation of water-bird populations. The purpose of this study is to find a way conservation of rice fields in connection with paddies's laws, for example, amend the Conservation of Wetlands Law or legislate for the conservation of paddies.

Land prices reflect not only the uses of land, but the potential uses as well(Plantinga, 2002) so land values can be applied to very effective indices for deciding regional status and growing potential. The purpose of this study is to deduce determinant factors of regional land prices. Principal determinants of regional land prices are analyzed with a hedonic technique and spatial econometric models based on 2001 statistic data of Korea except large cities. The results provide the followings. 1. The spatial effect of rural regions are very little with adjacent regions. 2. The common index of land price is population density and other determinant factors are different depending on land uses.

In this paper, an algorithm that finds man-made structures in a praylevel aerial images is proposed to perform stereo matching. An extracted contour of buildings must have a high accuracy in order to get a good feature-based stereo matching result. Therefore this study focuses on the use of edge following in the original image rather than use of ordinary edge filters. The Algorithm is composed of two main categories; one is to find candidate regions in the whole image and the other is to extract exact contours of each building which each candidate region.. The region growing method using the centroid linkage method of variance value is used to find candidate regions of building and the contour line tracing algorithm based on an adge following method is used to extract exact contours. The result shows that the almost contours of building composed of line segments are extracted.

Purpose: Sebaceous carcinoma is a rare malignant tumor that occurs mostly in head and neck regions. Early diagnosis and treatment are necessary because it tends to be locally aggressive and goes through distal metastasis with fast progression. This study presents reliable surgical methods for sebaceous carcinoma in head and neck regions. Methods: Three patients were included in this study. First, a 61-year-old woman visited the hospital with a yellow-colored, slowly growing mass on the left ala. A 54-year-old woman had a brown-colored mass on her right preauricle. Last case was a 62-year-old man who had a yellow-colored mass on his scalp. CT scan and punch biopsy were done. All cases were diagnosed as sebaceous carcinoma. The lesions were resected with 10 mm safety margin and various regional flaps were used for reconstruction. Results: Histological examination revealed sebaceous differentiation and local invasions. Postoperatively, all patients did not suffer from complication and no recurrence was found. Conclusion: We recommend early wide excision with an enough safety margin, and a regional flap as a treatment of sebaceous carcinoma.

Interests in the Polar Regions have been growing due to various factors such as depletion of natural resources and advanced resource development technologies, accelerated rate of polar ice melting as a result of global warming, etc. In particular, demand for the workforce related to vessel passage using the Northern Sea Route and polar studies is still expanding. The International Maritime Organization adopted the Polar Code in 2015 for the safety of ship operation in polar waters and it will enter into force from 2017. But education and training section in the code has been prescribed only for the safe navigation in the ice covered waters intended for navigational offices. There is no basic safety training requirement that applies commonly for all personnel exposed to the risk of the polar regions and the relevant study or discussion has not been made so far. Therefore, this study provides basic data for developing safety training courses for crew and other personnel by analyzing relevant regulations on polar safety training and the contents of relevant safety training in offshore industry required by the costal states adjacent to arctic ocean.

Phaeosphaeria species are pathogenic on wheat, barley and a wide range of wild grasses. To analyze mating type loci of the Phaeosphaeria species and investigate mating type distribution in Iran, we sequenced mating type loci of 273 Phaeosphaeria isolates including 67 isolates obtained from symptomatic leaves and ears of wheat, barley, and wild grasses from two wheat growing region in Iran as well as 206 isolates from our collection from other regions in Iran which were isolated in our previous studies. Mating type genes phylogeny was successfully used to determine the species identity and relationships among isolates within the Phaeosphaeria spp. complex. In this study, we reported seven new host records for Phaeosphaeria species and the Phaeosphaeria avenaria f. sp. tritici 3 group was first reported from Iran in this study. Mating type distribution among Phaeosphaeria species was determined. Both mating types were present in all sampling regions from Iran. We observed skewed distribution of mating types in one region (Kohgiluyeh va Boyer-Ahmad) and equal distribution in the other region (Bushehr). However, when considering our entire dataset of 273 Iranian Phaeosphaeria isolates, the ratio of mating types was not deviated significantly from 1:1 suggesting possibilities for isolates of opposite mating type to interact and reproduce sexually, although the sexual cycle may infrequently occur in some regions especially when the climatic conditions are unfavorable for teleomorph development.

산업의 발전을 위해 자원개발이 필수적인 현시대에 육상자원의 고갈로 인해 극한지에 관심이 몰리고 있다. 그러나 극한지 자원개발을 위해서는 극한지의 환경을 이해하고 이에 맞는 건설기술 확보가 우선되어야 한다. 극한지에서 자주 나타나는 외부환경 중 특히 융해침하는 자원을 이송하는데 필수적인 배관에 치명적인 영향을 준다. 따라서 배관이 융해침하에 의해 어떤 영향을 받는지 예측하고 분석하는 것이 중요하다. 본 연구에서는 융해침하 시 배관의 매설깊이에 따른 영향을 분석하기 위해 3차원 모델을 개발하여 유한요소해석을 진행하였다. 이러한 극한지의 환경과 배관해석을 참고하여 Elasto-plastic이 고려된 배관이 받는 응력 및 변위를 분석하고 경향성을 알아보았다.
