본 연구는 사회 불안이 높은 사람들이 얼굴 표정을 해석할 때 사회 불안이 낮은 사람들에 비해 보다 부정적으로 해석하는지와 얼굴 표정의 재인에 있어서 편향이 있는지를 알아보기 위해 실시되었다. 350명의 대학생 중에서 사회 불안이 높은 대학생 20명과 낮은 대학생 20명을 선발하여 컴퓨터 화면을 통하여 동영상으로 20명의 얼굴 표정을 보여준 후에 각 얼굴에 대하여 직장동료라고 가정하였을 때 본인에게 얼마나 호의적, 혹은 비판적으로 대할 것 같은지를 판단하게 하였다. 또한 일정한 휴식 후에 20명의 얼굴 표정을 더하여 총 40장의 얼굴 표정을 사진 자극으로 제시하면서 재인과제를 실시하였다. 추가적인 연구로 얼굴 표정이 있는 간단한 그림자극에 얼굴 표정 관련 형용사를 생성하게 하였으며 휴식 후에 재인과제를 실시하였다. 실험 결과 동영상을 통한 20명의 얼굴 표정 판단에서는 사회 불안이 높은 집단이 좀 더 부정적으로 판단하는 편향이 발생하였으나 인물의 재인 과제에서는 두 집단 간 차이가 나타나지 않았다. 그림 자극을 통한 형용사 생성에서도 두 집단 간의 유의미한 차이는 없었으며 재인 과제에서도 차이는 나타나지 않았다. 판단 편향에 비하여 기억 편향에 집단 간 차이가 없는 것, 그리고 추가적으로 실시한 그림 자극 과제의 의미에 대하여 논의하였으며 사회 불안 장애에 관한 정보처리적 접근과 그와 관련한 본 연구의 제한점과 시사점에 대하여 논의하였다. The purpose of this study is to examine whether students with high social anxiety interpret facial expression more negatively than students with low social anxiety and whether their recognition of facial expression are biased. 20 students with high social anxiety and 20 students with low anxiety had been selected from 350 university students. After seen 20 faces in a short movie by computer, subjects were asked to judge how critical or acceptable each person would be on the assumption that they were colleagues(1-critical, 7-acceptable). Also, after certain recess, photos of previous 20 faces and new 20 faces were presented as an unexpected recognition task. As an additional study, subjects were ask to produce relative adjectives to simple facial pictures and were tested for recognition. As a result, subjects with high social anxiety were more negatively judged facial expression of 20 faces in a short movie than subjects with low social anxiety. However, in the recognition task concerning a short movie, there were no group difference. Also, there were no group differences in a picture stimulus test producing relative adjectives and recognition task concerning pictures. The result of Memory bias and judgemental bias were compared and the meaning of an additional test concerning picture stimulus were discussed. Finally, implications of these findings and information-processing approach to social anxiety disorder were suggested.

Infection is a major complication and potentially life-threatening in patients with acute leukemia. The patients require prompt broad-spectrum antibiotics therapy when fever develops. One of the keys to successful patient management is the recognition of institutional trends of the spectrum of infections and infecting microorganisms. So we evaluated 138 patients with acute leukemia and blastic crisis of chronic myelogenous leukemia admitted to Seoul National University Hospital from July 1986 to June 1992. The results are following: 1) Total number of febrile episodes was 224 and 60% of them occurred after chemotherapy. 2) Microbiologically-defined infection, clinically-defined infection, and unexplained fever accounted for 28%, 45%, 27% of the febrile episodes respectively. 3) Fifty-eight percent of microbiologically-defined infections were caused by gram-negative bactria, and 36% were gram-positive bacteria. There was a tendency to a greater proportion of gram (+) organisms than that of the last study (p>0.1). Escherichia coli was the most common organism, and coagulase-negative staphylococci, Pseudomonas aeruginosa, Klebsiella pneumoniae were common in decreasing order. 4) Pneumonia was the most common type of infection, followed by skin and soft tissue infection, perianal infection, gingivitis and primary septicemia. 5) Seventy-two percent of total infections improved with therapy and this success rate was higher than that of the last study(p<0.001).

This study was carried out to improve the culturing method of P. cocos, on saving labor and inoculation amount. Therefore, the result of this experiment was as the following. Proper mycelium growth and density of P. cocos was observed in MCM(mushroom complete medium). In the selection of tree species, pine and larch had better in spawn culture and sclerotia formation condition. In the experiment of pine, Yield was 33.7㎏/3.3㎡. In inoculation amount, conventional method(cross slice inoculation) required 16 ~ 20 bottles/1000cc of spawn. In contrast, short log,drilling inoculation method required 8 ~ 10 bottles/1000cc, 2 ~ 3 bottles/1000cc of spawn, which reduced by 50% and 85 ~ 90% of inoculation respectively. In conventional method, the yield of pine was 23.4㎏/3.3㎡. In the case of drilling and short log inoculation, Yield was 28.7㎏ / 3.3㎡(25㎜ / depth) and 30.1kg / 3.3㎡(35mm / depth), 31.7㎏ / 3.3㎡ respectively, Therefore, short log inoculation was increased by 25% and 35% compared with conventional method. In conclusion, management cost was also saved.

This study was carried out to investigate changes of chemical compositions content affected by five harvest times in Lycium chinense M. The general conponents of L. chinense shoot were 6.25~8.74% moisture, 2.02~2.43% crude fat, 14.15~18.21% crude protein, 4.01~10.56㎍/㎎ total sugar, 1.07~1.93㎍/㎎ reducing sugar, and 10.3~15.8% ash. Total fatty acids were highest in linolenic acid (25.7~37.1%), followed by linoleic acid (21.9~26.7%), palmitic acid (13.5~18.8%), stearic acid (3.3~6.5%) and lowest in oleic acid (1.6~3.2%). Approxinately 50% of the total fatty acids consists of essential acids, linoleic and linolenic acids. The contents of inorganic matters were 4.25~7.16% K2O, 0.75~1.13% P_(2)O_(5), 0.43~0.86% CaO, 0.32~0.59% MgO, 120~429ppm Mn, 138.0~293.0ppm Fe, 3.0~26.1ppm Zn, and 0~23.3ppm Cu. Total free sugar and organic acid contents were 28.0~131㎎/g, 307.9~489.3㎎/g, respectively. Nineteen kinds of amino acids were extracted. It was found that glutamic acid had the highest content (10.0~10.9%) followed by aspartic acid, glycine, alanine, leucine and lysine, respectively. The content of tannic acid was 11.0~19.1㎎/g. There were no significant changes in the levels of effective components during different harvest times. The consistency of the levels of effective components may be due to the uniform cutting length of the Yuseong-2 and Cheongyang native shoots.

콘크리트 슬레브 증간깊이에 발생한 수평균열에 의한 스폴링, 펀치아웃같은 손상들이 연속철근콘크리트 포장(CRCP)에서 관찰되었다. 수평균열의 원인을 밝혀내기 위해서 현장실험과 더불어 수치해석을 수행하였으더 코어를 채취하여 콘크리트 슬래브 내에 수평균열의 분포를 조사하였다. 수평균열의 원인들을 파악하기 위해 설계, 재료 및 환경에 관련된 다양한 변수들을 현장 실험 및 수치해석시 고려하였고 CRCP의 수치해석 모델은 유한요소법을 사용하며 개발하였으며, 이 모델에 의해 소사된 CRCP내의 전단 및 인장응력 분포로 현장실험으로부터 얻은 결과들을 확인하였다. 횡방향 근열부근에서 슬래브 중간깊이에 위치한 철근부근에서 가장 높은 전단 및 인장응력이 발생함을 수치해석 결과를 통해 확인하였다. 수평균열이 할생한 단면과 그렇지 않은 단면의 란성계수와 열팽창계수같은 현장타설 콘크리트의 물성치 및 시공단계에서의 환경 조건들에 대한 평가가 수치해석결과가 타당함을 됫받침해준다. Severe spalling and half-depth punchout failures associated with horizontal cracks at the mid-depth of concrete slabs were observed in continuously reinforced concrete pavement (CRCP). To identify the causes of those horizontal cracks, field observations, laboratory tests, and numerical analyses were conducted. The extent of horizontal cracking in the concrete slab was investigated with coring. Several variables relative to design, material, and environment were considered in the field and laboratory studies to evaluate possible causes of horizontal cracking. Numerical models of CRCP were developed using the finite element discretization and the shear and normal tensile stress distributions in CROP were investigated with the models to verify the results obtained from the field and laboratory studies. Numerical analysis results show that maximum shear and normal tensile stresses develop near the depth of steel bars at transverse cracks. Evaluations of in-situ concrete material properties, such as modulus of elasticity and thermal expansion coefficient, from sections with and without horizontal cracks and environmental conditions during construction all support the results of the numerical analysis.

Food security, especially in developing countries, has been threatened by several factors. Fluctuations of food production world wide and its price are caused by unstable weather condition. Even when enough is produced, control over food-producing resources and distribution causes hunger. Population growth and limitted food production could lead to widespread famines. North Korean food shortage around 300million MT a year threatens the food security of the nation as well as that of South Korea. Several alternatives were suggested such as (1) development of high yielding technologies, (2) redistribution of control over food-producing resources in North Korea and (3) enhancement of cultivated land use in winter, etc.
