  • 이 연구는 치어기 뱀장어 Anguilla japonica의 사료 내 맥반석(quartz porphyry, QP)과 BAISM을 단독 및 혼합 첨가가 성장과 내병성에 미치는 영향을 확인하고 첨가제로써 이용성을 평가하였다. 사료 내 첨가 물질로 맥반석(Quartz porphyry, QP)과 실험실에서 제작한 섭취 촉진 물질인 BAISM(BS)을 기초 사료에 각각 0% QP+0% BS($Q_0B_0$), 0.7% QP+0% BS($Q_{0.7}B_0$), 0.7% QP+0.3% BS($Q_{0.7}B_{0.3}$), 0.7% QP+0.5% BS($Q_{0.7}B_{0.5}$), 0.7% QP+0.75% BS($Q_{0.7}B_{0.75}$), 0.7% QP+1.0% BS($Q_{0.7}B_{1.0}$)의 6가지 수준으로 첨가하였다. 실험어는 4주간 예비사육 후, 평균 어체중 $15{\pm}0.3g(mean{\pm}SD)$인 치어기 뱀장어를 60 L 사각수조에 실험구별 30 마리씩 3반복으로 무작위 배치하여 8주간 사육실험을 진행하였다. 사육실험 종료 후, Edwardsiella tarda 복강 주사에 의한 누적 생존율을 조사하였다. 증체율, 일간성장률, 사료효율, 단백질전환효율에서 맥반석 단독 첨가구($Q_{0.7}B_0$)와 맥반석 BAISM 복합 첨가구($Q_{0.7}B_{0.3},\;Q_{0.7}B_{0.5},\;Q_{0.7}B_{0.75},\;Q_{0.7}B_{1.0}$)는 대조구($Q_0B_0$)에 비하여 유의하게 높았다(P<0.05). 특히, 맥반석 BAISM 복합 첨가구들 중 BAISM 0.5% 이상의 실험구($Q_{0.7}B_{0.5},\;Q_{0.7}B_{0.75},\;Q_{0.7}B_{1.0}$)는 나머지 실험구들에 비해 유의하게 높았고(P<0.05), 이들에 대한 유의한 차이는 없었다(P>0.05). 전어체 일반성분의 분석결과 수분 함량은 전 실험구에서 유의한 차이가 없었고(P>0.05), 단백질 함량은 첨가수준에 따라 유의적으로 증가한 반면(P<0.05), 지질과 회분의 함량은 유의적으로 감소하는 경향을 나타내었다(P<0.05). E. tarda에 의한 공격실험 결과 주사 15일 후, 맥반석BAISM 0.5% 이상 혼합 첨가구의 누적 생존율은 다른 실험구에 비해 유의하게 높았고(P<0.05), 전 실험구에서 40% 이상의 누적 생존율을 나타내었다. 따라서 치어기 뱀장어 사료에 맥반석 0.7%와 BAISM 0.5%를 첨가하는 것이 성장과 사료효율 증대 및 질병 저항성 증진에 효과가 있을 것으로 판단된다.

  • This study had conducted to push our society for getting some proper measures of the anti-drug abuse and adopting this study as a fundamental data for the school health education. Sample subjects were the 3rd grade of high school in Chungnam Province and the number were 1,014. The data had been collected on Dec. 3th-8th, 1990 according to the tool of Institute on Drug Abuse of Korea. And then Frequency and $x^2-test$ were need to analyse of data by SPSS-X program. The results of this study could be summarized as follows. 1. They had used 14 kinds of drugs: $70.1\%$ of the subjects students used alcohol, $69.2\%$ analgesics, $38.6\%$ cigarette, $15.0\%$ stimulants, $14.7\%$ antitussives, $11.2\%$ antithistamines, $8.9\%$ hypnotics, $7.1\%$tranquilizers, $4.2\%$ inhalants, $2.3\%$ marijuana, $1.4\%$ hallucinogens, $0.9\%$ cocaine, $0.6\%$ amphetamines, and $0.6\%$narcotics. The boys' drug using rate is higher than girls' except in analgesics and stimulants. 2. With respect to misbehaving, $43.0\%$ of the students said they had pop houses, $42.4\%$ adult video, $17.4\%$ unexcused absence from school, $11.0\%$ dangerous weapon, $9.1\%$ sexual intercourse, $70.1\%$ disappearance from home, 8.0% blackmail, and $6.0\%$ assault. In every kinds of misbehaving, the boys' misbehaving rate is higher than the girls'. 3. Almost every kinds of drugs have the students first used at the age of 15 through. 18. And $13.8\%$ of the students smoked every da·y and $1.7\%$ drank every day. 4. The frequency of the drug using such as cigarette (p<.01), marijuana (p<.05), cocaine (p<.05) and narcotics (p<.05) showed the stastically significant differences according to the religions of the subjects 5. The subjects who has complaints about someone use more drugs than the ones who doesn't, and who doesn't have any complaints about five elements have never used drugs such as marijuana, cocaine, amphetamines, narcotics, hallucinogens, and inhalants. 6. The drug using subjects have the more experiences of adult video, pop houses, and unexcused absent from school than the non-drug using ones. It means that the subjects who use drug were apt to do misbehaving more often than the ones who have never used them, and delinquent boys and girls use more drugs.

  • The purpose of this study is to promote health for young female workers. It is based on questionnaires collected from 215 female workers in Incheon area. This study includes health condition (fatigue scores), occupational disease, knowledge of abused drugs and the actual condition of drug use. The results are summerized as follows: - $47.4\%$ visited their health center and were treated with diseases like cold and headache $(34.9\%)$, gastroenteric disease $(6.5\%)$, trauma $(7.9\%)$ and chronic disease such as diabetes and hypertension $(3.3\%)$ - $44.7\%$ received regular health education and $4.7\%$ among them received education on abused drugs. - $20.5\%$ were suffering from work related diseases such as gastroenteric disease, headache, trauma, repiratory disease, skin problem, arthritis, low back pain, shortsightness and tuberculosis. - Total mean fatigue score as an indication of health status was $9.0\pm5.4$ points out of 30 points. Physical mean score (group I) was $3.92\pm2.2$ points and psychological mean score was $2.5\pm2.3$ points and neurosensory mean score was $2.6\pm2.1$ points out of each 10 points. - They recognized analgesics $(55.0\%)$ and the next are laxatives $(49.8\%)$, inhalants $(40.0\%)$, narcotics $(24.2\%)$, stimulants $(24.0\%)$, antihistamines$(5.9\%)$, diuretics $(3.0\%)$, tranquilizer $(2.4\%)$ and sedatives $(1.4\%)$ - They used analgesics $(37.2\%)$ the most and then laxatives $(6.0\%)$, stimulants$(5.6\%)$, diuretics $(1.9\%)$, antihistamines$(0.5\%)$, And nobody used tranquilizer, sedatives, narcotics and inhalant. - The relationship between career, drug abuse education, health center utilization and and the actual condition of drug using was examined. The longer the career and the more educated with drug abuse, the less drug used. And those who utilized health center rarely used more drugs. - The relationship between career, health center utilization, the score of fatigue and use of analgesics was also examined. Those group who have a longer career above 3 years and the group who have never used health center used more analgesics. And the group of fatigue score above 11.0 points used a little more analgesics than the other group. These results indicate that analgesics are the most frequent used drugs among female workers. Those analgesics such as geborin, penzal, saridon, aspirin, tyrenol should be used properly. These basic data is submitted for the education and consultation which are carried out by industrial nurses for promoting health of industrial workers.

  • Cytokines are hormone-like proteins which mediate and regulast inflammatory and immune responses. Transforming growth factor -$\beta$1(TGF-$\beta$) plays an important role in the control of the immune response and wound healing, and in the development o various tissues and organs, Nitric oxide(NO) is major messenger molecule regulating immune function and blood vessel dilation and serving as a neurotransmitter in the brain and peripheral nervous system. Also, NO is to be a potent mutagen that cause mutation in the p53 tumor suppressor gene in early phases of human gastric carcinogenesis. The purpose of this study was to investigate the effect of Helicobacter phlori lystes, lipopolysaccharide (LPS), and Staphylococcus enterotoxin B(SEB) on production of TGF-$\beta$1 and NO by human fibroblasts. Primary cultured human fibroblasts were incubated with H. pylori lysates(Hp), LPs, SEB, Hp+LPS, Hp+SEB, Hp+LPS+SEB. Cultured supernatants that were collected at 24, 48 and 72 hr were assessed for TGF-$\beta$1 by enzyme-linked immunosorbent assay and NO production by quantification of nitrite ion. TGF-$\beta$1 production in fibroblasts exposed with Hp, LPS or SEB for 48 hrs was enhanced, but for 72 hrs inhibited. Its production by doble exposure such as Hp+LPS, Hp+SEB, Hp+LPS+SEB was lowered in comparison with single exposure of Hp in cases of 24 and 48 hrs incubation, but for 72 hrs decreased in Hp vaculoating toxin(+), increased in Hp vacuolating toxin(-). No production in fibroblasts increaed at all doses of LPS. But its production by exposure of SEB increased or decreased according to dose and incubation time. Also, NO production by Hp vacuolating toxin(+) increased at all doses, but its production by Hp vacuolating toxin(-) decreased. Its production by doble exposure such as Hp+LPS, Hp+SEB, Hp+LPS+SEB decreased in comparison with single exposure Hp Therefore, quantities pf TGB-$\beta$1 and NO released by human fibroblasts shows differences according to kinds of stimulants. Also, in care stimulated with same kinds of stimulants, its productions exhibit quantitative differences according to exposure times. These results suggest that the decreased of TGF-$\beta$1 in fibroblasts by mixed exposure with Hp producing vacuolating toxin and bacterial toxins such as LPS and SEB may effect negatively in healing of host tissue and increased of NO by infection oh H. pylori may related to the increased susceptibility for human gastric carcinogenesis.

  • I. Introduction Since the 1970's drug abuse among young people has increasingly become a social problem in Korea. In the 1980's, drug abuse, especially glue sniffing, has become the cause of many unfortunated incidents resulting in harm to others as well as the abusers themselves. Taking into consideration of the seriousness of this problem, the Republic of Korea National Red Cross initiated a nation-wide research programme, to understand the present situation and to raise the level of public awareness. The goal of this research was to begin a nation - wide campaign against drug abuse. The research team was composed of the Advisary Committee members and the staff of the Youth Department of the Republic of Korea National Red Cross. The data were collected in February 1988 with the collaboration of the staff and volunteers in the local Chapters. The respondents were allocated nation-wide by the quota sampling method. The questionnaires were distributed to the respondents in three groups :2, 700 to junior and senior high school students, 605 to working youths, and 916 to delinquent youths. A total of 4, 221 questionnaires were collected. II. Characteristics of the Respondents The respondents in each group were selected evenly from rural and urban areas. The general characteristics of the respondents can be described as follow: in case of students, the proportions between male and female respondents, and between senior high school and junior high school students were almost evenly distributed. In case of working youths, the proportion of females (80.5%) was higher than those of the students and the delinquents groups. Delinquent youths were defined as those currently being under custody of the centers for juvenile delinquents. Of this number, 38.8% and 68.2% were junior and senior high school drop-outs respectively. The majority of them (92.6%) were male. As for the family background of the respondents, the proportion of those residing in poverty - stricken areas, and the proportion of those from broken families were higher in case of working youths and delinquent youths than those in case of students. III. Present Patterns of Drug Abuse The following summarizes the presents of drug abuse, as tabulated from the results of the survey. 1. Smoking The percentage of youths who smoke was 36% in the student group, 32% m the working youths group, and 94.4% in the delinquent youths group. 2. Alcohol 50.3% of students, 71.6% of working youths, and 93.3% of delinquent youths has experienced drinking alcohol beverages. 3. Tonic: non - alcoholic, caffeinated beverages popular in Korea and Japan The percentage of those who have used tonic at least once was over 90% in all of the three groups. 4. Sedative About 70% of each group has used sedative with the proportion of working youths use higher than those in other groups. 5. Stimulants Those who have used stimulants comprised around 15% in each group. 6. Tranquilizers Somewhat less than 5% of students and working youths, and 28% of delinquent youths, have used tranquilizers. 7. Hypnotics The users of hypnotics amounted to 0.4% of students, 2.6% of working youths and 7.1% of delinquent youths. 8. Marihuana Those who have used marihuana indicated 0.7% of students, 0.8% of working youths, and 13% of delinquent youths. 9. Glue-sniffing The percentage of glue-sniffing was 3.7%, 5% in the students group and in the youths group respectively, but the proportion was unusually high, at 40.7% in the delinquent youths group. From the results of the survey the present situation of drug abuse in Korea can be summarized as follows: 1. A high percentage of Korean youths have experienced smoking cigarettes and drinking alcoholic beverages. 2. Tonics (non - alcoholic, caffeinated beverages), antipyretic analgesics and stimulants quite regularly used. 3. Tranquilizers, hypnotics, marihuana and glue-sniffing are more widely used among delinquent youths than the other youths. From this fact, there exists a correlation between drug abuse and juvenile delinquency. IV. Time-series Analysis of the First Experience of Drug Abuse and Deviant Behaviour The respoundents were asked when they were first exposed to drugs and when they committed deviant acts. By calculating the average age of each experience, the following pattern was found (See Figure 1). Youths are first exposed to drugs by abuse of tonic(non - alcoholic, caffeinated beverages). At the age of 13, they amoke cigarettes, the use of antipyretic analgesics begins at 14 year old, while at the age of 15, they use tranquilizers, and at 16 hynotics. The period of drug abuse which starts from drinking caffeinated beverages and smoking cigarettes and ends in the use of hypnotics takes about three years. During this period, other delinquent behaviours begin to surface, that is, at the age of 13 when smoking cigarettes begins, the delinquent behaviour pattern starts with truancy. Next, they start taking money from others by using physical force. Prior to the age of 15, they are suspended from school, become hostile to adults, begin running away from home, and start using stimulants and alcohol. Soon they become involved even in glue-sniffing and in the use of marihuana. At the age of 15, they begin to see adult videos and carry weapons. Sexual promiscuity and usage of tranquilizers follows the viewing of adult videos. Consequently, by the time they reach the age of 16, they visit drinking establishments, and are picked up by police for committing delinquent acts. And finally, they come to use hypnotic - type drugs. From the above descriptions, drug abuse can be assumed to have a close correlation with delinquent behaviour. V. Social Factors Related to Drug Abuse As for the Korean youths, glue-sniffing is found to he related to aggressive delinquency, in such cases as run - aways, being picked up by the police, and taking money by force. Smoking cigarettes and drinking alcohol is found to be related to seeing adult videos and visiting drinking establishments. Hypnotics and marihuana were found to be representive of drugs which are related to degenerational delinquency, irrespective of social delinquency. The social factors connected with these drug abuse are as follows: 1. Individual factors Male students were more heavily involved in the usage of drug than females. Youths who do not attend church were more likely to be involved in drugs than those who attend. 2. Family factors The youths who were displeased with their mothers smoking and those who thought their parents did not love each other, or those whose parents had used drugs without prescription, were more likely to he drug users. 3. School factors Those youths who found school life boring, were unsuccessful in their studies, spend most of their time with friends, feel their teachers smoke too much, those who had a positive perception of their teachers smoking were likely to he drug users. To sum up, drug abusers depend on the influence of their parents, teachers and peers. IV. Reasons for Drug Abuse Korean students have mainly used drugs to release stress (42.8%), to stay awake (19.7%), and because of the easy accessibility of drugs( 16.6%). Other reasons are due to their ignorance of the side effects of the drugs (3.6%), natural curiosity (4.2%), and to increase strength(3.O%). From the above facts, the major reasons for drug abuse among Korean youths are to release stress and to stay awake in order to prepare exams. Furthermore, since drugs are readily available, we can conclude that drug abuse is caused by the school system(such as entrance exams) in Korea. VII. Conclusion Drug usage among Korean youths are relatively less common than those of western youths. In some cases, such as, glue-sniffing and use of stimulants, the pattern of drug abuse is found. Moreover, early drug abuse is evident, and it has a close connection with deviant behaviour, resulting in juvenile delinquency. Drug abuse cannot be attributed to any one social factor. Specifically, drug abuse depends on parents, peers, teachers and other members of the community, and also is influenced by social institutions such as the entrance exam system. Every person and organization concerned with youth must participate collectively in restraining drug abuse. Finally, it is suggested that social agencial working for youth welfare should make every effort to tackle this serious problem confronted by the Korean youths today.

  • This study investigates the changes inconsumer sensibility and product preferences according to theirecofriendly productperceptions. Stimulants (released by three companies of sport casual brands)include three shirts made of recycled polyester and three made of organic cotton. A surveymethod was used to respond to the emotion and image while watching the presented pictures of the clothes. The change in the reactions was analyzed before and after the presentation of eco-friendliness information. The questionnaire consists of sensibility adjectives, open-ended questions about the associated image of eco-friendliness, color attractiveness, product favorability, price satisfaction, and reasons for an eco-friendly productpurchase. The survey was conducted on 200adult male and female participants. Two factors ('eco' and 'design')were identifiedthrough the factor analysis of image adjectives. There was a statistically significant increase in the evaluation of sensibility, color attractiveness, product favorability, and price satisfactiondue to the re-evaluation of the same products after consumers recognized the eco-friendly information of apparel products. When consumers recognize products aseco-friendly, they evaluate the products more positively than before. The result of the analysis of the increases by textile materials shows no significant difference in the sensibility changes depending on the materials. However, with regard to 'eco', the increase of sensibility change for organic cotton products was larger than for recycled polyester products.
