  • The purpose of this research was to investigate the image dimension depending on the coloration of the Korean jacket of cromatic colors and the Korean skirt of acromatic color and to elucidate the image difference depending on the tone variation of the Korean jacket and the Korean skirt. The experimental materials used for this study were sets of stimulus and response scales(7 point semantic). The stimuli manipulated by computer simulation were 48 color pictures with various combinations of colors of jackets and skirts. The subjects were 576 female undergraduates living in Jinju city. This experiment was based on the $3{\times}4{\times}4$ factorial designs: jacket color(red, yellow and green), jacket tone(vivid, light, dull and dark), and skirt tone(N9, N7, N4 and N2). Image factor of the stimuli consisted of 4 different dimensions(youthfulness and activity, gracefulness, visibility and tenderness). Among them, the youthfulness and activity, and the gracefulness were important. According to the tone variation of Korean jacket of cromatic colors and Korean skirt of acromatic color, the images for a wearer were expressed diversely and showed the difference in image dimensions.

  • 본 연구는 인삼 extract가 동물의 조건회피반응에 양호한 영향을 미친다는 petkov 및 홍사악등(洪思岳等)의 이전 연구 결과를 재확인하기 위해 인삼 extract 대신 화학적으로 더욱 정 선된 saponin으로 바꾸고 또 인삼 투여량도 다양하게 했을 때 그 결과가 어떻게 되는가를 알아 보고자 하였다. 60마리의 흰쥐 숫컷을 피험동물로 삼아 매일 실험 25분전에 인삼을 복강으로 투여하고 왕복회피형 shuttle box에서 하루 30시행씩 조건반응을 6일간 계속하였다. 총 180시행중 전기충격을 받지않고 성공적으로 회피한 조건반응수(CR)를 성적의 지표로 삼아 투여량에 따른 각 무리간의 CR수를 식염수 통제군의 CR수와 비교하였다. 모든 인삼 saponin을 투여한 집단들은 식염수 통제집단에 비해 조건회피반응 수가 많은 경향을 보여주나 통계적으로 유의미한 차이는 아니었다. 조건회피반응 중 동물들이 나타낸 배변수는 두 대량 인삼군 (50mg 및 100mg/kg)에서 통제군에 비해 유의미하게 적었다. 이 결과는 인삼이 학습에 어떠한 영향을 미치는지에 대해 확실한 증거를 제시치 못하는 것이나 대량의 인삼이 배변수를 줄이는 것으로 보아 대량의 인삼은 중추신경 안정작용이 있을 것으로 추측되게 한다.

  • To investigate the actual condition of the adult-smoking in Chinan County. I used self-reporting questionnaires among 923 residents living in nine districts selected at random among the sites of eleven eup-myons from December 28. 1998 to January 6. 1999. collected data and analyized using SPSS. The smoking rate of adults in Chinan County was $36.9\%$. There was a significant difference in smoking rate according to the age. gender, education and job among general characteristics. The smoking rate in group of above 40s was about $40\%$ and that of the male took $55.5\%$ which was higher than that of female and the smoking rate of the people having high-school education was the highest$(46.2\%)$. With regard to the career. the smoking rate of the farmers ranked first$(46.1\%)$. Therefore anti-smoking business for smokers should be focused on above 40 years old, males. people having high school education and farmers. As the result of the survey of smoking habits of 340 people who smoke currently, the average smoking begining age was 21.8 and $81.5\%$ among them was between 16-25 years old. $4.4\%$ was under 15. during around the elementary school. Most motives to smoke were as followed; curiosity or taste$(33.6\%)$, relief of stress $(31.2\%)$, peer presure$(26.5\%)$ And considering the amount of the cigarette which is smoked per day, the case which is less than a pack of cigarettes was highest as $75.5\%$ and the people who smoke over one pack of cigarettes took $24.5\%$. As for the kind of tobacco which is smoked, how to smoke and the desire for the smoking, most case was toxin was moderate$(47.8\%)$ or mild$(46.9\%)$. shallowly$(49.0\%)$ or deeply$(46.3\%)$ and under stress$(33.4\%)$. after meals$(27.8\%)$, during drink$(15.7\%)$ and so on. The highest point marked among the factors of smoking motives was 'the reduce of negative emotion' $(3.27\pm1.00)$. followed by 'uncomfortable habits' $(2.87\pm1.02)$, 'addiction' $(2.84\pm1.06)$. 'habit' $(2.74\pm1.12)$. 'pleasure' $(2.70\pm1.04)$. 'stimulus' $(2.59\pm.90)$, 'sensation-exercise satisfaction' $(2.42\pm.97)$. Smokers smoke to reduce the negative emotions when angry in most common case. depressed. anxious. uncomfortable. lone. ashamed or embarrased. and intend to solve the certain problem. etc. Other motives are uncomfortable habit. addiction. habit. pleasure and the pursuit of stimulus. The level of nicotine dependence of adults m Chinan County was 10.57 which amount to 'high' wholly. As the resulf of the level of nicotine dependence score. the people who are low in the level of nicotine was $33.5\%$. the people who are high was $48.2\%$. very high was $18.4\%$. The approach for anti-smoking for smokers should be conducted differently according to the level of the nicotine. For the people who are in low level of nicotin dependence the prohibition of the smoking should be guided through the approach to foster strong will. for those who are in 'high' by acquiring proper method for the prohibition of smoking. and for those who are 'very high' the anti-smoking should be induced by providing proper program because of the possibility of the suffer from abstinence syndrome. The difference of the level of nicotine with the general characteristics of the objects had not statistically significant difference. The difference of the level of nicotine dependence accompanied by smoking habit had statistically significant difference according to the amount of smoke, the kind of tobacos. smoke inhale habit. In other words, the group of heavy smokers had higher level of the nicotine dependence than that of the light smokers relatively and the group which smoke strong taboaco has higher level of nicotine than that of which smoke mild or moderate. And the group of smokers who smoke deeply has higher level of nicotine than that who smoke shallowly or nonswallow. Aa a result of the analysis of the correlation between smoking motive factors and the level of nicotine, there was the indication that people who smoke for the decrease of the negative emotion. habit, pleasure. stimulus. sensation-exercise satisfaction had high level of the nicotine dependence. As the result of the anti-smoking will of smokers. $65.0\%$ of them had prohibition of smoking will. $29.3\%$ had no will to quit smoke. The most important reason for anti-smoking was health. $67.9\%$ had experience to try to quit smoke and the biggest reason to fail to quit smoking was the lack of the will power to keep anti-smoking. $52.8\%$ of them were advised to stop smoking from their spouses or children. only $2.8\%$ were by medical. The people who have the opinion to need anti-smoking education were $69.6\%$. Therefore when the business for the hygine of the mouth for adult is set. it should be centered on the people who have intention of prohibition of the smoking and help to quit smoking by way of other affirmative counter-program not smoking under stress.

  • In birds, the photoperiodic seasonal breeding involves encephalic photoreception at the initial step of triggering the well-known endocrinal cascade. Especially in Japanese quail (Coturnix coturnixjaponica), the reproductive neuroendocrine function responds to a single long day, and hypothalamic regions are known to be important for the reproductive response. However, little is known about where and how the light and time signals are integrated to detect daylength information and transduced to the endocrinal responses. To gain insights into this issue, we are interested in the c-Fos expression in the hypothalamus of the Japanese quail. Meddle and Follett (1997) previously identified two hypothalamic regions where c-Fos-like immunoreactivities were induced in response to a long day by using an antibody to carboxyl terminal region of human c-Fos (Lys$^{347}$ -Leu$^{367}$ ). In the present study, we used a different anti-c-Fos antibody recognizing a region from Lys$^{128}$ to Ala$^{152}$ of human c-Fos, and found in long-day- stimulated quails many c-Fos-like immunoreactive nuclei localizing within two regions, nucleus anterior medialis hypothalami and nucleus periventricularis hypothalami, which are distinct from those identified in the previous study. Then, we focused on the difference in the cross-reactivities of the antibodies used, and determined the whole coding sequence of quail c-Fos to compare the antigenic sequences of the two antibodies with the amino acid sequence of quail c-Fos. We found that the antibody we used would recognize quail c-Fos more specifically than that used in the previous study.

  • The purpose of this study was to investigate the differences and interaction effects in impression formation according to eyeglasses, earrings, hair length, and clothing color worn by woman in Her 20s. A quasi-experimental method was used for this study. The experimental design was a $3{\times}2{\times}2{\times}4$(eyeglasses${\times}$earrings${\times}$hair length${\times}$clothing color) factorial design. The model of stimulus photographs was a woman with an oval shape face in her late twenties. She wore a tailored collared jacket with a white dress shirt. The subjects were 362 female college students. First, the women wearing glasses were found to be more potent but gave more negative impressions in terms of loveliness, politeness, and attractiveness than the women without glasses. Second, the women wearing earrings were perceived to have higher individuality, attractiveness, potency, loveliness, and elegance than the women without earrings. Third, the women with short hair were evaluated to have higher individuality, potency, and elegance, and to have lower loveliness, politeness, and attractiveness than the women with long hair. Fourth, the red clothes were perceived to have the higher individuality, loveliness, and attractiveness than the dark red or grey clothes. The light grey clothes were considered as the most elegant and the dark grey clothes were shown to have low attractiveness. Fifth, the women wearing the horn-rimmed glasses with short hair were evaluated to have high individuality. The women wearing glasses with short hair were evaluated lower in loveliness than those with long hair. The women with short hair, wearing glasses without earrings were evaluated very low in attractiveness.

  • The purpose of this study is to abstract the image from black dress, which has been favored by many people regardless of the times and examine it throughout the history of drss and thereby clearly define the images that black limplies in dress. Color image is a visual symbol, an image that forms through a combination of visual stimulus created by color, coupled with all the external factors related to it. Black is a one-dimensional color, of which the impact is subjective to its energy, which depends on light reflected on the object, and its texture. Therefore, black projects different images, depending on its surroundings. In general, black has had negative connotations in the Western culture. In dress, however, it has implied other various images different from the general negative ones. By combining general images of black and those exprssed in dress, major images of black were categorized into dignity, elegance, eroticism, asceticism and tragedy. Dignity is a category similar to the sublime. Dress with dignity has sharp contours and is generally made of velvet or silk which can be characterized by their splendor and voluminous-ness, exaggerating the body of a person wearing it. Such costume is mostly found in powerful countries in history such as Burgundy Court in the 15C, Spain in the 16C. Netherlands in the 17C. Elegance evokes grace and beautifulness. It includes elegance, grace, beauty and dandyism as subcategories or silk. Good examples are dandies' black costume and Ladies black and white dressees in the 19C. Eroticism is an image which expresses sexual attractiveness. Costume with eroticism is made of velvet or silk, which project sumptuousness through reflection. Such costumes expose parts of the body or are tightly tailored in order to emphasizes body contours. Asceticism means restraint from physical and mental desires. Costume with asceticism makes a person wearing it look smaller by covering the whole body. Puritan's black dresses and Bourgeoisie's black suit are good examples. Tragedy is anguish. sorrow. Black costume with grievous feelings such as mourning dresses is made of lusterless textile concealing most of the body except for the face.

  • The purpose of this study was to provide the guidance in more objective and proper clothing design and a strategy of fashion marketing from consumer sensibilities about adult women's town wear in un-limited circumstance. The specific objectives were 1) to investigate relationship between fashion sensibility and consumer sensibility of Good and Bad women's town wear, 2) to compare fashion sensibility with consumer sensibility of Good and Bad women's town wear, and 3) to investigate a dimension of Good and Bad women's town wear in fashion sensibility. Because they can affect estimators, the collected photos at shopping mall, department stores, and churches (S/S, F/W: April 28, 2004~May 1, 2005) were prepared removing face and background and attached on gray board. To investigate consumer sensibilities, the stimulus were 80 photos (40 for 'good', 40 for 'Bad'). The questionnaire consisted of bi-polar 25 pairs adjective scale of consumer sensibility was distributed 600 female (20's~40's) living in Busan (June 28, 2005~July 11, 2005). The data were analyzed by ANOVA, Regression analysis, and MDS. The results of practical study are summarized as follows. Fashion sensibility on the preference in Good and Bad women's town wear is closely related in 'want to buy-do not want to buy' and buying need is 'like-dislike'. For the fashion sensibility dimension at Good women's town wear, X axis showed from Young to Adult and Y axis showed from Hard to Comfortable following positioned design characters. For the fashion sensibilities dimension at Bad women's town wear, X axis showed from Young to Adult, Y axis showed from Normal to Unique, and Z axis showed from Heavy to Light following positioned design characters.
