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.

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.

There has been a study about the effective multimedia education using a computer following the appearance of a virtual space. Also, there has been an effort to connect the information & communication technology with education. The popular on-line lecture systems are mostly on English lecture sites. However, they just offer the YOD(Video On Demand) services ignoring students' convenience. To improve these week points, we design and implement the multimedia leaching system focusing on an efficient repeat-effect in order that students can control the Media Player by clicking a sentence on a web page. This paper presents the Editor and Player considering students' interest and the effective learning fruits. So users can easily make multimedia materials and use them to improve their English listening skill.

고지연,강항원,이재생,김춘송,박성태,김복진 한국환경농학회 2004 한국환경농학회지 Vol.23 No.2

영남지방 벼-보리 이모작답에서 가장 널리 시행되고 있는 보릿짚 처리방법인 소각이 대기환경에 미치는 영향을 소각시 발생하는 온난화가스, 대기오염가스 및 분진발생량을 중심으로 살펴보았다. 보릿짚 소각시 온난화가스 발생량은 CO₂376.8, CH₄ 1.56, N₂O 0.05 kg/10a 로서 CO₂의 발생량이 가장 많았으며, 대기 오염가스 중에는 유기물의 불완전 연소시 배출되는 CO발생량이 28.8 kg/10a로서 가장 많았다. 그 외 SO₂ H₂S, NH₃, NO등의 질소 및 황 함유 유해가스도 소량 발생되었고 발생된 PM 10 분진의 대부분은 인체에 미치는 영향이 PM 10보다 큰 PM 2.5로 이루어져 있었다. 또한 수확시기가 빠르거나 수분함량이 높은 보릿짚일수록 온난화가스 및 대기오염 가스의 발생량이 증가하고 소각 연기내 PM 10 분진중 PM 2.5의 미세분진 비중이 높았다. 수확적기로 알려진 출수 40일 이후의 보릿짚은 출수 후 40일된 보릿짚 소각시 발생하는 대기오염가스 발생량과 큰 차이가 없었다. This study was carried out to determine impacts of burning of barley straw produced from rice-barley double cropping paddy field on air quality by investigating emissions of greenhouse gases (CO₂, CH₄ and N₂O), air pollution gases (CO, SO₂, H₂S, NH₃ and NO) and particulate matters (PM 10 and PM 2.5). When the barley straw at a rate of 4.5 t/ha was burned at open status, the emitted GHGs amounts were CO₂ 376.8 kg/10a, CH₄ 1.56 and N₂O 0.06. The amount of CO emission was the largest among air pollution gases. These results showed that the range of 45~55% of total C in barley straw was emitted as CO₂-C, followed by CO-C (6.4~5.9%) and CH₄-C (0.5~0.7%). As far as moisture content in barley straw is concerned, the higher moisture content that the barley straw contains, the larger amount of air pollution gases and the higher portion of PM 2.5 in PM 10 were emitted when it burned. In case of harvesting time of barley straw, emission amounts of greenhouse, air pollution gases and PM 2.5 portion in PM 10 had tendency to increase when earlier harvested barley straw was burned.

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.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.
