Ground subsidence has occurred in the downtown of Muan-eup in Korea. Integrated geophysical survey, including two-dimensional resistivity, CSMT(Controlled source magnetotelluric), magnetic, borehole logging, GPR and resistivity tomography, has been conducted to investigate the cause of subsidence and ground conditions. Since the target area is in the city downtown, there were no spaces for surface geophysical methods. To get regional geology and to facilitate the detailed geophysical interpretation in the survey area, two-dimensional resistivity, CSMT and magnetic surveys have been applied in the outer region of the downtown. From these results, we could accurately define the Gwangju fault system and estimate the geologic conditions in the downtown. For the detailed survey of the downtown area, resistivity tomography and borehole logging data have been acquired using a few tens of densely located boreholes. Among these survey results, borehole logging data provided the guide to classification of the rock type and we could define the geologic boundary of granite and limestone formations. From the resistivity tomograms of 42 sections, which are densely located enough to be interpreted in a three-dimensional manner, we could delineate the possible weak zones or cavities in the limestone formations. In particular, resistivity tomograms in the subsided area showed the real image of ground subsidence. The map of hazardous zone has been derived from the joint interpretation of these survey results and we could provide the possible reinforcement strategy in this area.

본 논문에서는 Active Shape Models(ASM)과 상태기반 모델을 사용하여 동영상으로부터 얼굴 표정을 인식하는 방법을 제시한다. ASM을 이용하여 하나의 입력 영상에 대한 얼굴요소특징점들을 정합하고, 그 과정에서 생성되는 모양변수벡터를 추출한다. 동영상에 대해 추출되는 모양변수벡터 집합을 세 가지 상태 중 한 가지를 가지는 상태벡터로 변환하고 분류기를 통해 얼굴의 표정을 인식한다. 분류단계에서는 표정별 표정변화에 따른 변화영역의 차이를 고려한 새로운 유사도 측정치를 제안한다. 공개데이터베이스 KCFD에 대한 실험에서는 제안한 측정치와 기존의 이친 측정치를 사용한 k-NN의 인식률이 k가 1일 때 각각 89.1% 및 86.2%을 보임으로써, 제안한 측정치가 기존의 이진 측정치보다 더 높은 인식률을 나타내는 것을 보인다.

Xinjiang Uygur Autonomous Region is the area with the most Muslim populations in China and the costume of this ethnic minority group was influenced from its surrounding environment and religion. Headgear is one of the important costume elements of Muslim ethnic minority such as Kazakh, Kirghiz, Uzbek, and Tadzhik people, and each group has developed narious forms of it. Especially, we can notice characteristics of headgear in Xinjiang Uygur and four ethnic minority groups through women's headgear pursuant to motive of wear, classification of type, differences and comparability with other areas. Thus, purpose of this study is to investigate women's headgear of Muslim ethnic minority in Xinjiang Uygur Autonomous Region. Based on local data at the Xinjiang Uygur Museum, the study referred to Chinese ethnic minority costume and literature data as well as advanced researches related to Islam, and analyzed characteristics of women's headgear of four ethnic groups in connection with Muslim formation background in Xinjiang Uygur. Women's headgear of Muslim ethnic minority in Xinjiang Uygur can be largely divided into three types; cylindrical, conical and hood type. Headgear was influenced not only by natural environment and weather for protection of body, but also by Islam. Along with strong desire for decoration and expression of racial features, it was used as a means of race discrimination and representation of identity. The religion of Islam within these four ethnic groups grew in accordance with tradition of existing nomadic tribes and regional characteristics, and women's headgear developed in various ways added with religious precepts and nomadic features. Taking everything into consideration, it is found that women's headgear of Kazakh, Kirghiz, Uzbek, and Tadzhik people developed, adopting their own living style and features of minority races instead of remaining identical to the headgear type of Muslim countries in other area.

Farmland spatial data are needed as a basic information in conducting rational use of farmlands in regional scale. This study develops a method that can be used to make up such farmland spatial data in a simple way and to develop a technique to manage them in a unitary way, and examines the effectiveness of the technique by applying it to the case area. A method that Web-Service Raster Image and Digital Cadastal Map can be utilized as a base map was devised. It was designed applying the vector system, in which one lot of farmland is area unit. Raster image and field survey data were combined to increase the accuracy of data. The lot boundaries of the existing boundary map were adjusted to the shapes of actual farmlands using GIS edition function. A proper farmland use classification system to the area characteristics was established and data obtained from the field survey were coded. Usually it is very difficult to identify the size of one lot of actual farmland in the existing space data, based on the results of the case study, the result map showed actual topography very realistically. Also the frequently occurring lot divisions and the serious topographical modifications by natural disasters frequently have made it impossible to survey farmlands on the catastral map in the field. But the final map had a great usefulness in that it may solve such problems by expressing the filed survey results graphically.

Objectives: This study was performed to estimate domestic usage amount of insecticide for fruit cultivation to suggest job-exposure matrix(JEM) regarding farmers treating agricultural insecticide. Materials and Methods: The domestic usage amount of insecticide for fruit cultivation was investigated according to two research methods. The former method is to use agricultural pesticides published annually from Korea Crop Protection Association(KCPA) and the latter method is to apply cultivation area of fruit provided officially from Statistics Korea(SK). Results: It was found that its domestic usage amount has decreased gradually from the first sale to presence(2012). However, there is a significant difference of annual usage trend of insecticide for fruit cultivation between shipments and estimation. The annual usage trends of insecticide for fruit cultivation based on regional classification were different from those based on total aspect. Conclusions: The region which used insecticide for fruit cultivation the most in Korea was as follows: Gyeonsang-do, followed by Jeolla-do, Chungcheong-do, Jeju-do, Seoul/Gyeonggi-do and Gangwon-do. An averaged ratio of usage amounts of insecticide based on shipments and those based on estimation by cultivation area was $980{\pm}186%$, which means that usage amounts of insecticide estimated by shipments are ten times higher than those based on cultivation area.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease characterized by fever and thrombocytopenia. Haemaphysalis longicornis ticks comprise the major population of ticks in the environment and have been considered as the main vector for SFTS virus (SFTSV). Here we investigated the distribution of ticks carrying SFTSV collected from the environment using the dragging or sweeping methods during April~October 2015 in Jeollanam-do, Korea. Sampling was taken from Songjeong, Omi, Bangkwang, Sandong areas in Jiri walking trails. Among the total 3,869 ticks collected, 3,823 ticks (98.8%) were H. longicornis, 41 (1.1%) were Amblyomma testudinarium, and 5 (0.1%) were Ixodes nipponensis. Classification results by regional groups of H. longicornis indicated that 1,613 ticks were collected in Sandong, 1,190 ticks in Omi, 603 ticks in Bangkwang, and 417 ticks in Songjeong. In monthly distributional studies of H. longicornis based on the developmental stages, nymph (325 ticks) was collected from May to October, 94% of larvae from April to June, and 94% of adult from June to August. These results showed the different dominant stage of ticks according to seasons. However, no SFTSV-specific gene was detected in 3,823 ticks of H. longicornis, 41 of A. testudinarium and 5 of I. nipponensis.

Backgroud: We have performed the CT-guided celiac plexus block (CPB) using anterior approach to evaluate the safety and efficacy of the procedure and to determine the role of CT. Methods: CPB were done in 10 patients (5 men and 5 women: mean age, 58.1 years) with intractable upper abdominal pain due to terminal malignancy of the stomach (n=3), pancreas (n=4), gallbladder (n=2), and liver (n=1). To permit an anterior approach, patients lay supine on the CT scan table during the procedure. One 21-guage Chiba needle was placed just anterior to the diaphragmatic crus between the celiac and superior mesenteric arteries and 10~12 ml of dehydrated alcohol was injected. Degree of pain relief following the procedure was assessed and pain was graded on a numeric rating scale (NRS) from 0 to 10. Results: The results suggest a direct relation between the degree of celiac invasion and the response to the CPB. With CT guidance, it is possible for us to direct the needle into more accurate region, allowing alcohol to be deposited in specific ganglion area. Conclusions: CT-guided CPB using an anterior approach was an easy and effective way of reducing intractable upper abdominal pain due to terminal malignancies. CT-guidance allowed precise needle placement and safe procedure. Careful classification of cases is important to predict the degree of pain relief using the grading system based on the degree of involvement of the celiac plexus.
