기독교는 배아파괴로 인한 생명윤리문제를 들어 배아줄기세포연구에 반대하는 입장을 여러 차례 밝히고 신자들을 계도하고자 노력했으나 별다른 효과를 거두지 못했다. 이는 신자들의 태도결정에 교단의 입장 외에 다른 요인이 개입하고 있다는 것을 의미한다. 본 연구에서는 다양한 조사자료에 근거해 기독교 신자들이 배아 줄기세포에 대해 보이는 태도를 정리하고, 신자들의 태도형성에 영향을 미치는 요인을 동정하고자한다. 나아가 해당 요인들이 상호작용하는 과정, 신자들이 관련 정보를 해석하고 수용하는 과정에 보이는 특성 등을 정리하여, 배아연구에 대한 신자들의 태도결정에 종교적 요소가 미친 영향력이 제한적일 수밖에 없는 이유를 설명하고자한다.

The gas hydrates are probably most sensitive to climate change since they are stable only under specific conditions of high pressure and low temperature. One of the main factors responsible for formation of gas hydrates is the saturation of the gases with water vapor. Quantitative phase equilibrium data and understanding of the roles of water component in the phase behavior of the heterogeneous water-hydrocarbon-hydrate mixture are of importance and of engineering value. In this study, the water content of ethylene gas in equilibrium with hydrate and water phases were analyzed by theoretical and experimental methods at temperatures between 274.15 up to 291.75 K and pressures between 593.99 to 8,443.18 kPa. The experimental and theoretical enhancement factors (EF) for the water content of ethylene gas and the fugacity coefficients of water and ethylene in gas phase were determined and compared with each other over the entire range of pressure carried out in this experiment. In order to get the theoretical enhancement factors, the modified Redlich-Kwong equation of state was used. The Peng-Robinson equations and modified Redlich-Kwong equations of state were used to get the fugacity coefficients for ethylene and water in the gas phase. The results predicted by both equations agree very well with the experimental values for the fugacity coefficients of the compressed ethylene gas containing small amount of water, whereas, those of water vapor do not in the ethylene rich gas at high temperature for hydrate formation locus.

The purpose of this study was to investigate 1) the effects of clothing styles on impression formation of middle and high school students and 2) the differences in impression in relation to perceiver variablex(sex, age, residence). The sample consisted of 60 subjects in each of 8 perceiver groups according to sex, age and residence. Stimuli consisted of 10 color photographs of male and female adolescent wearing each of 5 clothing styles respectively. Questionnaires consisted of 43 seven-point semantic differential scales measuring perceivers responses to the stimuli, open-ended Question and perceiver’s clothing style preference. Responses to the semantic differential scale were factor analyzed and 4 factors - Self-confidence/refinement, Sincerity, Intelligence, and Sociability - were emerged to account for the structure of the impression of the male stimuli. Five factors - Sincerity, Refinement, Self-confidence, Sociability, Intellience - were emerged in case of female stimuli. One-way ANOVA results showed that clothing styles had the effects on all the factors of impression except Sincerity. From the reset analyzing the effects of perceiver variables on impressions, age had the effects in all the clothing styles, sex had the effects in 6 clothing styles, and residence in 5 clothing styles. Clothing style 5(male stimuli) and style 10(female stimuli) were the most preferred clothing style in all the subject groups.

It was studied the relationship between the red tide occurrence and the meteorological and oceanographic factors, the choice of potential area for red tide occurrence, and the satellite monitoring for red tide. From 1990 through 2001, the red tide continuously appeared and the number of red tide occurrence increased every year. Then, the red tide bloomed during the periods of July and August. An important meteorological factor governing the mechanisms of the increasing in number of red tide occurrence was heavy precipitation. Oceanographic factors of favorable marine environmental conditions for the red tide formation included warm water temperature, low salinity, high suspended solid, low phosphorus, low nitrogen. A common condition for the red tide occurrence was heavy precipitation 2∼4 days earlier, and the favorable conditions for the red tide formation were high air temperature, proper sunshine and light winds for the day in red tide occurrence. From satellite images, it was possible to monitor the spatial distributions and concentrations of red tide. It was founded the potential areas for red tide occurrence in August 2000 by CIS conception: Yeosu∼Dolsan coast, Gamak bay, Namhae coast, Marado coast, Goheung coast, Deukryang bay, respectively.

Piperlongumine (PL) is a natural product found in long pepper (Piper longum). The pharmacological effects of PL are well known, and it has been used for pain, hepatoprotection, and asthma in Oriental medicine. No studies have examined the effects of PL on bone tissue or bone-related diseases, including osteoporosis. The current study investigated for the first time the inhibitory effects of PL on osteoclast differentiation, bone resorption, and osteoclastogenesis-related factors in RAW264.7 macrophages stimulated by the receptor activator for nuclear factor-${\kappa}B$ ligand (RANKL). Cytotoxicity was examined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and osteoclast differentiation and bone resorption were confirmed by tartrate-resistant acid phosphatase (TRAP) staining and pit formation analysis. Osteoclast differentiation factors were confirmed by western blotting. PL exhibited toxicity in RAW264.7 macrophages, inhibiting osteoclast formation and bone resorption, in addition to inhibiting the expression of osteoclastogenesis-related factors, such as tumor necrosis factor receptor-associated factor 6 (TRAF6), c-Fos, and NFATc1, in RANKL-stimulated RAW264.7 macrophages. These findings suggest that PL is suitable for the treatment of osteoporosis, and it serves as a potential therapeutic agent for various bone diseases.

Objective: The primary objective of this study was to perform a retrospective evaluation of the radiological and pathological features influencing the formation of peritumoral brain edema (PTBE) in meningiomas. Methods: The magnetic resonance imaging (MRI) and pathology data for 86 patients with meningiomas, who underwent surgery at our institution between September 2003 and March 2009, were examined. We evaluated predictive factors related to peritumoral edema including gender, tumor volume, shape of tumor margin, presence of arachnoid plane, the signal intensity (SI) of the tumor in T2-weighted image (T2WI), the WHO histological classification (GI, GII/GIII) and the Ki-67 antigen labeling index (LI). The edema-tumor volume ratio was calculated as the edema index (EI) and was used to evaluate peritumoral edema. Results: Gender (p=0.809) and pathological finding (p=0.084) were not statistically significantly associated with peritumoral edema by univariate analysis. Tumor volume was not correlated with the volume of peritumoral edema. By univariate analysis, three radiological features, and one pathological finding, were associated with PTBE of statistical significance: shape of tumor margin (p=0.001), presence of arachnoid plane (p=0.001), high SI of tumor in T2WI (p=0.001), and Ki-67 antigen LI (p=0.049). These results suggest that irregular tumor margins, hyperintensity in T2WI, absence of arachnoid plane on the MRI, and high Ki-67 LI can be important predictive factors that influence the formation of peritumoral edema in meningiomas. By multivariate analysis, only SI of the tumor in T2WI was statistically significantly associated with peritumoral edema. Conclusion: Results of this study indicate that irregular tumor margin, hyperintensity in T2WI, absence of arachnoid plane on the MRI, and high Ki-67 LI may be important predictive factors influencing the formation of peritumoral edema in meningiomas.

Proliferation and differentiation of ovarian cells are regulated by gonadotrophins and various intraovarian factors, with many of their actions dependent on growth factors. Transforming growth factor-$\beta$ (TGF-$\beta$) has been reportedly involved in the regulation of ovarian follicular development. The overall objectives of the present study were to examine the influence of TGF-$\beta$1 expression in ovarian follicular development or yolk formation and to investigate the association of egg weight with ovarian TGF-$\beta$1 expression at 60 wk. Egg weights of 70 Korean Native Ogol Chicken (KNOC) were recorded from 20 to 60 wk. Ovaries were taken at 60 wk, and TGF-$\beta$1 was measured with ELISA, respectively. Based on egg weight up to 60 wk and TGF-$\beta$1 expression in ovary, the chickens were divided into high and low groups. Egg weights and follicle weight in the high TGF-$\beta$1 group were higher than those in the low groups. Also, TGF-$\beta$1 expression and follicle weight in high egg weight group were higher than those in the low groups. Taken together, the results indicate that TGF-$\beta$1 is associated with egg weight in KNOC. This association of TGF-$\beta$1 with egg weight in KNOC supports the report that TGF-$\beta$ is mainly involved in the development and differentiation of follicles in the poultry. Further studies about other endocrine factors related to yolk formation are required to fully understand the endocrine mechanism of egg weight in Korean Native Ogol Chickens.

The purpose of this study is to find out the effect of suit color, necktie color and necktie patterns on the men's suit image formation. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 28 color pictures manipulated with suit color, necktie color and necktie patterns by computer drawing. The experimental design consists of 3 factorial design; 1) suit color (navy blue, beige), 2) necktie color (analogous, complimentary color), 3) necktie patterns (plain, dot, stripe, check, paisley, floral, abstract) The 7-point semantic differential response scale designed for visual evaluation of men's suit image on suit color, necktie color and necktie patterns were composed of 34 bipolar adjectives. The subject are 150 female undergraduate students in Chin-ju city. They responded twice to 14 stimuli at random order The result of this study are as follows; 1. By analyzing the responses of the subjects, 4 factors emerged in the dimensional structure of the men's suit image formed by suit color, necktie color and necktie patterns. The 4 factors are charm, potency, uniqueness and tenderness. Among these, charming and potential factors proved to be more important. 2. necktie color, suit color and neckite patterns had the significant effect on the formation of men's suit image. In the charm image, only necktie patterns were proved to be the most dominant variable. The most dominant variable in the potencial and unique image was necktie color and second to it suit color was important. But suit color was most significant in the image of tenderness. 3. In the effects of interactions between each variables, the combination of suit color and necktie color wins more significant than that of suit color and necktie patterns and that of necktie color and necktie patterns, but in the image of tenderness, only the combination of suit color and necktie color was more significant. In the interaction of suit color, necktie color and necktie patterns, the potential factor didn't have the significant effect.
