This study was aimed to clarify the distribution of lymph follicles and germinal centers in the lymph nodes of the C_57BL/6 and nude strain mice. Male adult mice were used in this study. After animal were sacrificed, the right popliteal lymph nodes were removed and fixed in Zenker-formol solution for 3 hours and embedded in JB-4 resin. One of every two section, cut 3㎛ in thickness serially, was stained with May-Gru‥nwald and Giemsa solution. The results obtained from this study were as follows; 1. The number of lymph follicles per popliteal lymph node was average 11.25 C_57BL/6 mice but, the number of lymph follicles in nude mice was 20.25. In C_57BL/6 mice major distribution(8.5) of the lymph follicles situated in peripheral cortex overlying the unit(PCOU). In unde mice major distribution(14) is peripheral cortex beyond the unit(PCBU). 2. The thickness of most lymph follicles was between 0.01-0.19 mm in C_57BL/6 mice. But in nude mice the thickness of most of lymph follicles was between 0.20-0.39mm 3. The number of lymph follicies contained germinal center was 8.75 in nude mice. But C_57BL/ 6 mice was not observed germinal centers. 4. The average number of deep cortex is 1.5 and shape is semiovoid in C_57BL/6 mice. Spherical shaped deep cortex was observed and the number of that is one in nude mice. In stained section low density deep cortex was observed in nude mice specifically. 5. The size of lymph follicle in C_57BL/6 mice is 0.405mm and in nude mice 0.795mm

Investigating Directives in Korean: Advice and Suggestion

Jee-Won Hahn 국제언어인문학회 2010 인문언어 Vol.12 No.2

Investigating Directives in Korean: Advice and Suggestion Jee-Won Hahn (Kyung-Hee University) Even though it is based on a small number of responses, this study provides some interesting findings and implications for two directive speech acts. Advice and suggestion are examined from three aspects: conceptual, situational, and linguistic. These speech acts are shown to present similarities and differences as well. From a conceptual aspect, a set of semantic features are identified to distinguish advice and suggestion. The situational dimension offers the insight into the speech act theory (Searle and Venderveken 1985) to understand the condition for determining directive speech acts. Finally, linguistic realizations present various strategies employed for performing an act. Compared to advice, due to weakening illocutionary force, suggestion tends to be simplified in types of linguistic strategies. In addition, this study argues that a sentence-based approach needs to be complemented by a variety of pragmatic devices when it comes to the English-learning environment.

徐志瑗 숙명여자대학교 대학원원우회 1986 원우논총 Vol.4 No.-

The purpose of this thesis is to study on the licensing of foreign trade mark as a kind of technology transfer. As a method of this study, the data in "The Import of Technology by Individual Firms" which are published by Ministry of Science and Technology are analysed. This paper presents the condition of the import of license of foreign trade mark as a kind of import of technology, and shos the problems of itself and the derived problems. And as a conclusion some proposals for them are presented. The proposals for the business management side are as follows; (1) The diversification of licensor-country is needed so as to minimize the problems caused b the bias of licensor-country. (2) The minimization of the unfaimess on contracts caused by competitive imports of license of foreign trade mark is needed. (3) The selective import of licensing of foreign trade mark, excluding nonessential consumption goods, is needed. (4) The long-run purpose of an import of license of foreign trade mark should be eventually to produce high quality products by establishing our own trade mark. And for the proposals toward the national economic side; (1) There should be consistent post-administration to improve the ussage effect of foreign trade mark and to minimize it's vicious side effects. (2) The consummer could be protected from misunderstanding the home-made goods under the license of foreign trade mark as genuine foreign goods, by using the combined trade mark both of the licensor and the licensee. (3) The consummer should clearly recognize home-made products, and so buy-home-made-goods-movement also needed so much. (4) The consummer should have planned-buying behavior. And they should buy the goods by it's quality rather than brand.

강지현,유병연,서희선,심경원 대한비만학회 2002 The Korean journal of obesity Vol.11 No.2

연구배경 : 목둘레는 인슐린저항성과 관련된 여러 질환과 연관되어 있으며 인슐린저항성의 위험이 증가되어 있는 환자들에서 목둘레가 임상적인 선별검사로 유용하게 쓰일 수 있으리라고 제시되어진 바 있다. 따라서 본 연구에서는 목둘레와 비만 관련 지표 및 인슐린저항성의 지표로서의 HOMA score 와의 상관관계를 알아보고, 비만 환자를 예측할 수 있는 최적의 목둘레 분별점을 알아보고자 하였다. 대상 및 방법 : 건양대학병원 종합검진센터에 내원하여 건강검진을 받은 성인 남녀 대상자 364명 (남자 199명, 여자 165명) 중 249명 (남자 136명, 여자 113명) 실험군(test group)로 하여 receiver output curve (ROC) 분석을 통해 체질량지수 25 kg/㎡에 대한 최적의 (optimal) 민감도와 특이도를 가지는 목둘레 분별점을 구하였으며, 나머지 115명 (남자 63명, 여자 52명)을 유효군 (validation group)으로 하여 실험군에서 얻어진 목둘레 분별점을 적용하여 그 유효성을 알아보았다. 또한 묵둘레와 비만 관련 지표 및 인슐린저항성의 지표로서의 HOMA score와의 상관관계를 알아보았다. 결과 : 목둘레는 남녀 대상군 모두에서 허리둘레, 엉덩이 둘레, 엉덩이허리둘레비, 체질량지수, 체지방률, 공복시 혈중 인슐린, HOMA score와 강한 양의 상관관계를 보였으며 실험군에서 비만 환자를 예측할 수 있는 최적의 목둘레의 분별점은 남자에서는 36.6 cm 여자에서는 32.3 cm 였다. 이때의 민감도는 남자 81.92%, 여자 91.5%, 특이도는 남자 77.4%, 여자 69.7%, 정확도는 남자 80.2%, 여자 85%였다. 또한 실험군에서 얻어진 목둘레의 분별점을 유효군에 적용한 결과 남자에서는 민감도 91.9%, 특이도 53.9%, 정확도 76.1%로 나타났으며 여자에서는 민감도 81.25%, 특이도 85%, 정확도 82.69%로 나타났다. 결론 : 본 연구는 측정이 간편한 단순 비만 지표로서의 목둘레와 흔히 사용되는 비만 관련 지표 및 인슐린저항성과의 관련성을 밝혔으며 비만환자를 예측하기 위한 방법으로서 남자 36.6 cm, 여자 32.3 cm라는 목둘레의 분별점을 제시하였다. 향후 보다 일반화할 수 있는 보완 연구가 이루어져야 할 것으로 생각된다. Background : Neck circumference has been reported to be related to the other anthropometric measures of obesity and also associated with the metabolic disorders related to insulin resistance. The measurement of neck circumference could be useful in clinical screening for persons at an enhanced risk for insulin resistance. The aim of this study was to determine whether a single measure of neck circumference might be correlated with other obesity indices and HOMA score and to define neck circumference cutoff levels for obesity. Methods : We examined 364 consecutive persons (199 men and 165 women), who visited konyang university hospital health examination center during August, 2002. To find the optimal, maximal sensitivity and specificity for neck circumference, the receiver output curve (ROC) analysis of cutoff points against BMI (25 kg/㎡) was performed using the test group (136 men and 113 women). We validated the cutoff level using validation group (63 men and 52 women). Other obesity indices and fasting glucose and insulin were measured to find the correlation between neck circumference. Results : Neck circumference was significantly correlated with waist circumference, hip circumference, waist hip ratio, BMI, total body fat percent, fasting insulin and HOMA score. Neck circumference 36.6 cm for men and 32.3 cm for women was the best cutoff levels for determining the subjects with BMI over 25 kg/㎡. In the validation unrelated group, the test characteristics were acceptable with 91.9% sensitivity, 53.9% specificity, and 76.1% accuracy for men, and 81.25% sensitivity, 85% specificity, and 82.69% accuracy for women. Conclusion : Neck circumference as a simple and easy screening method for obesity was strongly correlated with the other conventional obesity indices and HOMA score as a index of insulin resistance and we defined neck circumference cutoff level for obesity according existing BMI cutoff levels.

조경원,한유경,서경혜,조정아,이지은 이화여자대학교 교육과학연구소 2006 교육과학연구 Vol.37 No.1

21세기 지식정보화 사회는 전통적인 학교교육의 변혁을 요구한다. 이에 학교교육 개혁을 성공적으로 이끌어 나아갈 수 있는 교원의 리더십 특히 학교행정가의 리더십이 절실히 요구되고 있다. 그렇다면 지식정보화 사회에서 요구되는 학교행정가의 리더십이란 무엇이며 어떤 역량을 포함하는가? 본 연구는 학교행정가의 리더십과 핵심역량에 대한 선행연구가 학교 현장과는 유리된 채 이론적, 당위적 수준에 그치고 있다는 문제의식에서 출발하여 학교행정가의 리더십을 구성하는 핵심역량이 무엇인가에 대한 교사, 교감, 교장, 행정실장 및 서무부장의 인식을 파악하고 이들 집단의 인식을 비교 분석하는 데 목적을 두었다. 이를 위해 우선 문헌연구를 통해 리더십에 대한 관점과 개념의 변화를 고찰하였고 변혁적 리더십 관점에 기초하여 학교행정가가 갖추어야 할 핵심역량으로 교육적 리더십, 학교 계획 및 조직, 학교교육과정 편성 및 운영, 학교운영, 인적자원 개발, 학교재정 관리, 교육법 이해 및 집행, 학교교육정책 이해, 학교·학부모 및 지역사회 협력, 정보통신기술 활용과 같은 열 가지 역량을 도출하였다. 문헌연구를 통해 도출된 핵심역량에 대한 학교 현장의 관점을 알아보기 위해 초·중·고등학교 교직원을 대상으로 10대 핵심역량의 중요도와 현재 실행정도에 대해 설문조사를 수행하였다. 설문조사에는 144개 학교의 교직원 1,136명이 참여하였다. The purpose of this study is to investigate the perspectives of teachers, vice-principals, and school staff on school administrators' leadership and core abilities. For this purpose, first, we examined the perspectives and concepts of school administrator's leadership and identified 10 core abilities that constitute the school administrator's leadership. Second, we developed a questionnaire to investigate the perspectives of teachers, vice-principals, and school staff on to what extent the 10 core abilities are important and whether their school administrators actually exert these 10 core abilities. Finally, we conducted a survey research, including teachers, vice-principals, and school staff with various years of experiences in elementary and secondary schools in Korea. The findings show that teachers, vice-principals, principals, and school staff consider the 10 core abilities very important for school administrators. However, they perceive that school administrators, in reality, do not exert the 10 core abilities as much as they think these abilities are important. In particular, teachers rated school administrators' leadership relatively low compared to principals, vice-principals, and school staff. The difference between their perception on the importance and exertion of 10 core abilities indicates the need for programs that promote the development of 10 core abilities for school administrators and consequently support the development of school administrator's leadership.
