This study aims to estimate the efficiency of soybean production using Data Envelopment Analysis, analyze the characteristics of efficient soybean agriculture using Tobit model, and calculate the efficient input-output levels of inefficient farmers using a frontier isoquant curve on the technical efficiency measures. The main results of this study are as follows: first, the technical and scale efficiency measures of the soybean farming were 0.832, 0.919, respectively; second, the average excessive levels of input cost are 9.1 hundred thousand won in 25 inefficient farmers.

하악 제 1대구치 매복의 발생 빈도는 전체 인구의 0.01%로 드물게 나타난다. 매복의 원인으로는 맹출 공간의 부족, 과잉치, 치성 종양이나 낭과 같은 맹출로상의 장애물, 유전적 요인, 내분비 질환, 외상 등이 있다. 하악 제 1대구치의 매복으로 인해 하안면 고경의 감소, 낭의 형성, 치관 주위염, 인접치의 치근 흡수, 부정 교합 등의 부작용이 생길 수 있으며, 치료 방법으로는 외과적 노출술, 교정적 견인, 외과적 재위치술, 발거 등이 있다. 다음의 두 증례는 하악 제 1대구치의 미맹출을 주소로 내원한 환아에게 외과적 노출술을 시행하여 원심 경사 매복된 하악 제 1대구치의 자발적 맹출을 유도한 증례들이다. Impaction of mandibular first molar is relatively rare and its overall frequency has been reported to be 0.01%. The etiology of impaction are lack of eruption space, physical obstacles such as supernumerary teeth, odontomas or odontogenic tumors, hereditary factors, functional disturbances of endocrine glands and traumas. Impaction of mandibular first molar can result in a short lower facial height, formation of a follicular cyst, pericoronal inflammation, resorption of the roots of neighboring teeth and malocclusion. The treatment options available for impacted teeth include surgical exposure, orthodontic forced eruption, surgical repositioning and surgical removal of unerupted molar. This report presents two cases of distally tilted and impacted mandibular first molars which were treated by surgical exposure. In these cases, we could observe spontaneous eruption of the impacted mandibular first molars after surgical exposure.

This study investigated the perceptions of elementary school teachers' on the science experimental training course using closed-form questionnare. 437 elementary school teacher, 21 school, 14 cities and counties in Gyung Nam province were selected as the objects for researching these matters. The results were as follows; First, without system and holding type teachers choose on the training not the same time but their ability freely. Second, to extend the trust the composition of place and instructor must be based on professor and research in the national university of education. Third, the composition of the text must be made of scientific growth based on important experimental activities teaching strategy, the using of materials. It must be increase multimedia training course on the science education. Fourth, the method of training course it must be happen on the experiment and discussion and it is necessary to grow up training level. Fifth, the type of training it must not give the score. Therefore it will be free and comfortable without difficulties. In the results, the improvement of science experimental training course is compatible on the purpose and it will help on the science teaching-learning.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

저자등은 전신적인 소양감을 동반한 홍반성 판상의 피부 병변과 자가 면역성 용혈성 빈혈이 동반된 Sezary 증후군을 진단하고 복합 화학 요법 CHOP으로 치료하여 피부 증상과 빈혈이 호전된 예를 문헌고찰과 함께 보고하였다. Sezary syndrome(SS), a leukemic variant of cutaneous T-cell lymphoma(CTCL), is monoclonal proliferation of CD4 T-cell having cerebriform nuclei in the skin and the peripheral blood. It is associated with erythroderma, pruritis, lymphadenopathy with protracted clinical course and systemic spread. We present a case of SS i a 38-year-old woman with generalized exfoliative erythroderma, plaques, and pruritus. Histopathologic findings of the skin lesions revealed infiltration of atypical lymphocytes in the dermis and epidermis. Electron microscopic findings of peripheral blood and skin showed atypical lymphocytes with cerebriform nuclei. Laboratory findings revealed direct Coombs' positive autoimmune hemolytic anemia, a rare association of SS. Chemotherapy with CHOP produced improvement of the skin manifestation and anemia.
