  • This is a descriptive study to understand the preventive stage for STDs to provide a basis for sex education for college students. The colleges were selected by quota sampling in five representative cities in Korea. but the 1,691 college students were selected by convenient sampling in the cities nationwide, and the data were collected by self-reporting using a questionnaire consisting of 33 items. The results were as follows : 1. Their mean ages were 21.8 for female and 23.3 for male students, 2.78.0% of the males md 46.5% of the females permitted premarital sex, 57.1% of male and 10.3% of female college students had experienced sexual intercourse, 7. l% of males and 2.4% of females had experienced pregnancy, 10.3% of males and 3.4% of females had been infected with STDs, 72.1% of male and 13.8% of female didn't use condoms at the time of infection. 3. Most of the factors related to STDs infection, such as drinking, smoking, frequency of sexual intercourse. pregnancy, knowledge of STDs, the score of STDs prevention were statistically higher in the male student group than in the female group. 4. The students' mean score of knowledge about STDs was similar between the male group(7.80) and the female group(7.84) with a possible score range from 0-18. 5. Only fifteen percent of male and 9.6% of female students expressed that they will do something to prevent STD. 6. The group having the experience of sexual intercourse(t=3.924, P=.048) and the group of having experience of contracting STDs(t=16.638, P=.000) had shown statistically higher STDs prevention score than the group not having that kind of experience. but the group having experience with pregnancy didn't show any difference from. the group not having experience with pregnancy. Considering that 57.1% of males and 10.3% of females had sexual intercourse experience, 78% of male and 46.5% of female permitted premarital sex, 10.3% of male and 3.4% of female had been infected with STDs. It could be concluded that the college students were ignorant about the prevention of STDs and had unrealistic stage of the STDs prevention. Therefore, enforcement of education for the prevention of STDs including the dynamics of the sexual intercourse and STDs infection is needed.

  • 철강산업은 우리나라의 대표적인 국가 전략산업으로 정부의 적극적 정책지원과 민간의 경영노력이 조화를 이루어 1970년대 이후 한 국경제성장의 견인차 역할을 해왔다. 그러나 우리나라의 경우 철강산업 원자재의 대부분을 수입에 의존하고 있는 실정이며, 이때 수입되는 원자재의 중량이 무겁기 때문에 철강산업은 수송업이라 할 만큼 수송비 부담이 큰 산업이다. 수송의 합리화는 철강산업의 주요한 과제라 할 수 있다. 따라서 본 연구에서는 철스크랩의 안정적인 공급확보 차원에서 철스크랩 수출입 관련 해상운송의 운송경로별(컨테이너선 vs 벌크선) 경제성을 분석하였다. 이를 위해서 먼저 국내외 철강산업의 현황에 대해서 살펴보았으며, 연간 세계 조강생산규모와 철스크랩 소비규모, 세계 철스크랩 교역구조를 분석하였다. 또한, 철스크랩 수출입 관련 컨테이너선과 벌크선의 두 운송수단 간의 수송물류비를 비교하기 위해서 "D 사(社)"의 철스크랩 수출입 운송시간과 운송비용 항목을 이용하여 톤당 물리비용을 산정하여 비교하였다.

  • Background: For standardizing of Han-Yeol [寒熱], which is a kind of diagnosis method in oriental medicine, it is necessary to investigate into relationship of symptoms and signs representative of Han-Yeol [寒熱] to the biofunctional medical signals; thermal temperature by Thermography, Pulse-Respiration Ratio and so on. By correlation analysis of these data items acquired from patients, it could be provides the fundamental data for standardizing of Han-Yeol [寒熱]. Objectives: We performed this study to check the characteristics of thermal temperature with Han-Yeol [寒熱] statue by pulse-respiration ratio. Methods: We selected nine regions around acupoints including Yin dang[印堂], Sugu[水溝, GV26], Ch'ondol[天突, CV22], Chonjung[CV17], Chung-wan[中脘, CV12], Chonchu[天樞 S25], No-gung[勞官, P8], and calculated based on the utility of R.O.I.(Region of Integer) by IR-2000 these points temperature from 68 subjects. In practicing pulse-respiration ratio over 4.0 means the statues of Yeol [熱], pulse-respiration ratio below 4.0 means the statues of Han [寒]. To optimum conditions thermal temperature, which are not effected by internal and external variables, we studied preceding research. The results shows that optimal time period is 20minutes after undressed and the optimal region is the region around acupoints including Sugu [水溝, GV26]. Based on a preceding research results, we analyzed these data by Paired T-test between GV26 Region and 8-Thermography Regions and two-way repeated ANOVA with thermography$({\Delta}T)$ and Han-Yeol [寒熱] statue by pulse-respiration ratio. Results: 1. In applying of two-way repeated ANOVA with thermography$({\Delta}T)$ and Han-Yeol [寒熱] statue by pulse-respiration ratio, Sugu [水溝穴, GV26] - [印堂穴, HN1], Sugu 水溝, GV26] - Chonjung[CV17], Sugu [水溝, GV26] -Chung-wan[中脘, CV12]had significant differences. 2. In applying of Paired T-test between Sugu [水溝穴, GV26] Region and 8- Thermography Regions, there were significant differences except of Sugu [水溝穴, GV26] -Chondolp[天突, CV22]. 3. In the difference of Sugu [水溝, GV26] -Chung-wan[中脘, CV12], thermal temperature increases a lot in the statues of Yeol [熱], thermal temperature decreases a lot in the statues of Han [寒]. Conclusions: On the analysis of Thermography, we obtain the measurement conditions were considered the individual variations. And it is different that the thermal temperature change on Thermography according to Han-Yeol [寒熱] statue by pulse-respiration ratio.

  • Purpose - This empirical analysis determines the structured causal relations between perceived value, customer satisfaction, and repurchase intention among users of traditional markets. The results of this analysis would help merchants and market operators indevisingan appropriate strategy to successfully manage traditional markets. Research design, data, methodology - The perceived value model of traditional markets includes functional value (price), functional value (quality), emotional value, and social value. In this study, the perceived value of traditional markets is considered as an independent variable, while customer satisfaction and repurchase intention are shown as the dependent variables, where customer satisfaction is also considered as the mediating variable. The study aims to ascertain the extent of influence of the perceived value of traditional markets on customer satisfaction and repurchase intention. We use regression analysis to verify the effects. The measurement items were already deemed as reliable and valid in the previous study, but for this purpose, we made some modifications. We distributed questionnaires to 300 consumers on a national scale, and finally used 241 consumer responses among these as a sample. We analyzed the data using the SPSS 21.0 statistical program. Results - We obtained the following results. First, the order of perceived value dimensions of traditional markets that positively impact customer satisfaction is functional value (price), social value, emotional value, and functional value (quality). Second, the perceived value sometimes directly affects repurchase intention; its effect is typically strong with customer satisfaction as a parameter. The order of perceived value dimensions that positively impact repurchase intention is social value, functional value (price), emotional value, and functional value (quality). Third, the perceived value significantly influences repurchase intention, with customer satisfaction as the mediating variable. Conclusions - We should recognize the importance of perceived value in retail distribution markets, such as traditional markets. Moreover, we need to develop strategies to improve the perceived value. The practical implications of the study are as follows. First, with regards to functional value (quality; price) dimensions, we should have an appropriate assortment of high quality products that are reasonably priced. In addition, customers are satisfied with the friendly service, discounts, and other benefits provided by the merchants. Second, in terms of emotional value dimension, we need to develop differentiated events that provide fun and emotional experience to the customers. Third, in the context of social values dimension, we should strive to positively influence society to enhance social image through activities such as social services and contribution to community development. On the basis of these results, we present the implications, limitations, and future directions for the research. One of the policy implications of the study is that merchants of traditional markets must actively select customers and develop customer value. However, this study is limited in the fact that the population used for data collection is not fully representative, as the survey only covered some specific areas. Moreover, future studies could also benefit with additional research using moderating variables.

  • Choo-Joo(鄒澍;1790-1844) was the medicine scholar who lived in the late peroid of the Chung-Dynasty and wrote "Bon-Kyung-So-Jeung(本經疏證)", "Bon-kyung-Sok-So(本經續疏)", "Bon-Kyng-Seo-So-Yo(本經序疏要)". In the books mentioned above, He annotated the chief effectiveness of herbal medicine(本草) which had been presented on "Shin-Nong-Bon-Cho-Kyung(神農本草經)" and "Myoung-Eui-Byul-Lok(名醫別錄)". He defined medical action of 315 herb-items with the many theories of various scholars. Scholars whom Choo-Joo has qoutated belong to the school of study of Chinese classics, and they have regarded "Hwang-Je-Nae-Kyung(黃帝內經)", "Shin-Nong-Bon-Cho-Kyung(神農本草經)" and "Sang-Han-Lon(傷寒論)" as great important cannon and have lived during the Myoung Chung Dynasty. The distinctive character of Choo-Joo belongs to similar academic traditions. It seems that he was appected mainly by "Bon-Cho-Gang-Mok(本草綱目)" written by Lee-Si-Jin(李時珍), Mok-Jung-Soon(繆仲淳)'s "Sin-Nonng-Bon-Cho-Kyung-So(神農本草經疏)", You-Yak-Guem(劉若金)'s "Bon-Cho-Sul(本草述)" and Yang-Si-Tae(楊時泰)'s "Bon-Cho-Sul-Gu-Won(本草述鉤元)". He contributed in two big sides. First, Choo-Joo(鄒澍) have achieved much contribution in biliographical study of Chinese classics(考證學). He analyzed the medical theory of herb-medicine, combining with "Nae-Kyung(內經)", "Sang-Han-Lon(傷寒論)" and many theory of various scholars in order to make research on the chief effectiveness that had been presented in "Shin-Nong-Bon-Cho-Kyung(神農本草經)". Therefore the practical application of medical theory and term which had been represented on classics were offered. Secondary, Choo-joo did great accomplishment in pharmacology. The point of his theory was grasping the effect of a medicine through distinctive one beyond general feature. He set up standards that grasp distintive feature as form, color, energy and taste, place of production and temper. And on the basis of these standards he investigated distinctive feature on various fields, then he induced 'the Uem-Yang-0-Haeng Theory(陰陽五行說)' from distictions. According to the these method of classification, form(形) stand for the resultant shape of herbal function, color(色) represent the active direction of herb, energy and taste(氣味) imply the ultimate active function of herb, the place of production(産地) and the period of occurrence(發生時期) symbolize symptoms. When he applied these method to seek for effetiveness, he regarded the field which revealed most representative feature as of great importance, and Combining remained distinctions with one another, he determined more accurate medicinal value. These method of obsevation solved contradiction which occured by equaly appling all medical herbs for the regular standard. The most important theory that represented in Choo-Joo(鄒澍) is to induce and to certify the distintive feature of herb into the 'Uem-Yang-0-Haeng Theory'. That is, concluded as "spring(生), growing(長), change(化), collecting(收) and storing(藏)". As the results of these studies, he made clear the action of medicine more concretly and made 'the Uem-Yang-0-Haeng Theory(陰陽五行說)' more concret and actual for applying. And he contrbuted to establish the standard for grasping the effect of medicines.

  • Purpose : To investigate the medical information related to HRT online and the medical treatment of perimenopausal and postmenopausal women in the Dept. of Ob&Gy Korean Medicine Hospital, after the discontinuance of the WHI trial in U.S, July 2002. Methods : With the key-words "HRT", "Hormone Replacement therapy", "호르몬 대체요법(HRT)", 갱년기 증후군(perimenopausal syndrome)", “폐경기후증후군(postmenopausal syndrome)", I searched for the information from July 2002 to 2005 on DAUM, the representative portal site in Korea, and I've got a grasp of the tendency of the informational propagation on HRT. Moreover, I investigated chief complaints and tendency of give up HRT of the perimenopausal and postmenopausal women(aged between 47 and 60) who visited Dept. of Ob&Gy Korean Medicine Hospital for 2 years and 6 months since July 2002. Results : 1) Searching for the news on DAUM, I found; 2 articles on the methods of HRT: 4 on the positive effects of HRT: 4 on the general items including the positive effects of HRT: 19 on the side effects of HRT: 1 on the insignificant effect of HRT :4 on the apprehensions about HRT: 3 on the strengthening of the criteria on medical fees review: 3 on the discontinuance of HRT: 8 on the alternative materials and medicines to HRT: 4 on the guidance for the phyto-estrogen. 2) I analyzed chief complaints of 120 women. The majority of chief complaints were vasomotor symptoms like hot flush and sweating. There were only 4 patients who wanted to give up HRT. Conclusion : The side effects of HRT were objectively dealt with online but there was not enough effective and continuous guidance. In the case that a woman not on HRT wishes to overcome perimenopausal period through KM therapy, this information may have affected her decision. However, not many women who were already on HRT terminated the therapy for fear of side effects and switched to KM therapy. Promotion of KM therapy in improving health during perimenopausal and postmenopausal period is desperately needed.

  • 한국은 지난해 주력수출품목인 승용차(HS 8703)를 전세계에 409억불 수출하였다. 그러나 인접국인 일본시장에의 수출은 대 전세계 수출규모와 비교한다면 거의 없는 수준이다. 비록 장기간 경기침체 속에 있다하더라도 일본 자동차시장의 신차판매는 연간 500만대 규모의 큰 시장이다. 이러한 관점에서 일본 자동차시장의 경쟁구조를 분석하여, 이에 적합한 한국 자동차기업의 대일 수출전략을 제시하는 것은 의미가 있을 것이다. 본고는 J. S. Bain에 의하여 정립된 상위기업집중율($CR_k$)과 이단경지(伊丹敬之)(Itami Hiroyuki) 등의 일본시장 특성에 관한 선행연구를 이론적 배경으로 하여, 일본 자동차시장의 경쟁구조 변화를 분석하였다. 그 결과, 일본의 자동차시장에서는 시장지배적 위치에 있는 기업이 존재하고는 있으나, 차종별로 들어가면 빅3의 지배력에도 상당한 차이가 발생하고 있을 뿐만 아니라 경쟁구조도 계속 변화하고 있는 것으로 나타났다. 이에 따른, 한국 자동차기업의 대일 수출전략으로 일본 자동차메이커와의 제휴를 통한 유통채널 상호활용 전략, 한국자동차의 브랜드전략, 일본사양(Designed for Japan) 개발을 통한 고급화전략 등을 제시하였다.
