The higher output levels attained by automotive engines recently been accompanied by an increase in the amount of heat released by the engine. This higher heat release level has caused the thermal load in the engine compartment to rise. As a result, greater emphasis has been placed on thermal analysis of heat radiation from the radiator and of heat release from the engine. Heat release the coolant from the engine is released with heat transfer. It is. thus, the essential element to analysis of heat transfer process in cooling system for an automotive engine. However, most of the research about heat release to the coolant is performed from the standpoint combustion, so this research is done from the standpoint of heat transfer to the cooling system including the engine coolant. This study is performed on the analysis of heat release chracteristics in cooling system for an automotive engine according to the operating and cooling conditions. The results are summarized as follows: 1. The heat release is increased according as coolant temperature is decreased and coolant flowrate is increased. 2. The heat release is increased and heat release per power is decreased according as engine is increased with same engine speed. 3. The heat release is increased by increasing fuel comsumption according as engine speed increased.

남녀평등교육의 두 접근방식에 나타난 교육기회균등과 가치 문제 분석

There are two approaches to education for women liberation. One is the gender-free approach which attempts to ignore gender or to be free from gender-bias in education. The other is the gender-sensitive approach which pays attention to gender in order to prevent gender bias and inequality. The first approach argues for co-education, having come to the realization that sex-segregated education has been both different and unequal. In contrast, the second approach calls for women-centered education since our society, education and perceptual frameworks are themselves too gender-biased. The gender-free education has been supported in the tradition of Liberal Feminism, while the gender-sensitive education has recently been claimed by the Radical Feminists and the Social Feminists. The Liberal Feminists tend to emphasize the same education for women as for men. Focusing on the alleged inferiority of women, they want to redress sexual inequality as a result the stereotyping of expected role s for men and women and the translation of these into curricula. They emphasize equal educational opportunities between the sexes by ignoring gender as an access barrier (from admission to specific educational institutions and programs to opportunities for participations). They claim for women an education in the "masculine" virtues of rationality and independent judgment, while they claim for men an education in the "feminine" virtues of nurturance and care. They argue that single-sex schools or classes have fostered different and unequal education for men and women. In this tradition, co-education has been a major trend in public schools since ignoring gender has enabled us to move to co-education. Acknowledging power relations between men and women, the Radical Feminists and the Social Feminists argue for women-centered education, which aims at empowering women to change their position and, therefore, society. Believing that our current educational system tends to perpetuate patriarchal social relation, they began to question the assumptions underlying co-education, examining the manner in which the school under-evaluates womens performance even when they do better than men at the same activity. Arguing that male control of education has shaped the nature of education and knowledge promulgated schools, they question the dominant code of knowledge, the styles of pedagogy, and the ideals of the educated person. Feminist Pedagogy in this tradition legitimates womans personal experience as an appropriate arena of intellectual inquiry when facing established knowledge about women and social reality. Taking the everyday lives of women seriously, they challenge what has been defined as significant or valuable in our society.

치조골의 흡수와 상악동의 함기화로 인하여 상악 구치부에서 임플란트 식립을 위한 상악동골이식술은 이미 보편화된 술식이며, 그 예후도 아주 양호한 것으로 알려져 있다. 최근 조직은행 등을 통하여 다양 한 동종골 이식재들이 공급되고 있으며 또한 그 이식재의 특성도 비교적 양호한 것으로 알려져 있다. 그러나 동종골 이식재는 비교적 흡수가 빨리 일어나는 단점이 있어서 이에 대한 보완으로 이종골이나 합성골을 섞어서 사용하여 이식재의 빠른 흡수를 줄이려는 노력이 있어 왔다. 저자는 상악동골이식술 시 동종골과 이종골을 섞어서 이식하는 것이 아니라 상악동저의 환자의 자기 골조직과 접촉되는 부분은 동종골을 이식하고, 상부의 상악동점막에 접촉하는 부분은 이종골을 이식하 여 흡수에 보다 저항할 수 있도록 동종골과 이종골을 층상으로 골이식술을 시행하여 비교적 양호한 결 과를 얻었다.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

β-1,3/6-linked glucan 첨가사료가 넙치의 비특이적 면역반응에 미치는 영향

원경미,김수미,박수일 한국어병학회 2004 한국어병학회지 Vol.17 No.1

glucan 첨가 사료 투여가 넙치에 미치는 영향을 조사하기 위하여 넙치에 glucan 0%, 0.01%, 0.1%, 0.5% 첨가 사료를 연속 투여구와 격주 투여구로 나누어 공급하면서, 성장, 혈액 성분, 비특이적 면역능을 분석하였으며, 나아가 어병 세균인 Edwardsiella tarda균의 공격 실험에 대한 방어능을 조사하였다. gulcan 첨가 사료 투여는 넙치의 성장에 긍정적인 효과를 보였는데, 특히 0.05% 연속 투여구와 0.1% 격주 투여구에서 대조구보다 유의하게 높은 성장을 나타내었다. glucan 첨가사료의 투여가 넙치의 비특이적 면역 반응에 미치는 영향을 조사하기 위해 혈청 lysozyme과 전신 식세포의 확성 산소를 측정한 결과, 거의 모든 실험구에서 실험 기간 내내 대조구보다 높은 활성을 보였다. glucan 첨가 사료의 투여가 넙치의 생리에 영향을 미치는 지를 조사하기 위하여, total protein, glucose, GOT, GPT, Ht를 측정한 결과, 3주째 GPT 수치가 다소 높은 것을 제외하고는 그다지 큰 변화를 보이지 않았다. 마지막으로 Edwardsiella tarda (4×10^(6) cells/fish) 균을 공격 실험한 결과, 0.01% 연속 투여구를 제외한 모든 실험구에서 높은 방어력을 보였다. The effects of dietary β-1,3/1,6-linked glucan administration on nonspecific immune responses, hematology and disease resistance against Edwardsiella tarda in olive flounder, Paralichthys olivaceus were evaluated. Fish were fed the experimental diets supplemented with 0 %, 0.01 %, 0.05 %, 0.1 %, and 0.5 % of β-glucan to a commercial diet for 7 weeks. The test was performed in two ways such as fed on each β-glucan concentrations daily and every other week alternately. The body weight gain from the fish fed on daily the 0.05 % supplemented diet and fed on alternately the 0.1 % supplemented diet of β-glucan were significantly higher than the control. Both lysozyme activity and intracellular superoxide anion production of kidney phagocytes were higher in the all experimental groups than in the control. But there was no large difference in hematology among each group. The relative percent survival rate (RPS) after an artificial challenge with 4×10^(6) cells of E. tarda per fish was higher than the control, except for that fed on daily the 0.01 % supplemented diet.

이경원,배성렬,김상철 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.1

임상교정에서의 원활한 치아배열을 도모하기 위하여 진단과 치료계획의 수립 방향에 따라 제1소구치 혹은 제2소구치 발치 또는 제2대구치 발치 또는 비발치로 치료가 진행된다. 이때 나타나는 하악제3대구치의 위치적 변화 특히 근원심, 협설측 경사도의 변화도를 알아보고자 163명의 교정환자 (비발치군 77례, 제1소구치 발거군 78례, 제2대구치 발거군 8례)의 치료전후 Pantomogram상을 분석하였다. 결과적으로 하악 제2대구치 발거군에서 치료전후 근원심 경사도의 변화가 컸으며, 하악 제3대구치의 초기 근심 경사도는 치료 전후의 근심경사도와 높은 상관성을 보였으며, 치료전후의 근심경사도 변화량과도 높은 상관성을 보였다. 비발치군과 제1소구치 발거군에서 치료전후의 협설경사도 변화의 차이가 인정되었다. 치료전후의 협설경사도 변화는 치료전의 협설 경사도, 치료후의 협설경사도, 치료후의 근심경사도, 치료전후의 근심경사도 변화량과 높은 상관성을 보였다. Most of orthodontic cases are treated with extraction of certain teeth, which influence the pre-eruptive movement of the lower third molar, The purpose of this study was to evaluate the positional change of lower third molar following orthodontic treatment. Pre- and post-treatment pantomograms of 163 orthodontic patients (77 nonextraction group, 78 first premolar-extraction group, 8 second molar-extraction group) were analyzed in terms of the mesidistal and buccolingual angles of lower third molar. The results were as follows. 1. The change of the mesiodistal angle of lower third molar by orthodontic treatment was significant in second molar-extraction group. 2. The mesiodistal angle of lower third molar in pre-treatment was significantly correlated to the mesiodistal angle in post-treatment and/or the change of the mesiodistal angle by treatment. 3. The change of the buccolingual angle of lower third molar by treatment was significant in non-extraction group or first premolar-extrction group. 4. The change of the buccolingual angle of lower third molar by treatment was significantly correlated to the mesiodistal angle in post-treatment, the change of the mesiodistal angle by treatment, the buccolingual angle in pre-treatment or the buccolingual angle in post-treatment.
