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.

글루타티온은 간 질환용 치료제 내지는 영양보충제로 시판되고 있다. 이전 실험에서 글루타티온 고함유 효모 Saccharomyces cerevisiae FF-8 균체(FF-8GY) 투여가 사염화탄소 및 알코올성 유발 간독성 개선효과를 나타내었다. 따라서, 알코올성 지방간의 산화 스트레스에 미치는 영향을 조사하기 위하여 시판되고 있는 글루타티온 고함유 효모 추출물(GYE)과 본 실험실에서 분리한 글루타티온 고함유 효모 FF-8GY을 비교실험 하였다. FF-8GY 또는 GYE 투여에 의한 간 조직 중의 산화스트레스 측정지표로서는 과산화지질(TBARS) 및 글루타티온 함량을 측정하였다. TBARS 농도는 간 조직 homogenize 분획에서 알코올 투여 대조군에 비해 FF-8GY 투여 실험군에서 5%수준에서 유의적으로 감소하였으며, GYE 투여에 의해서는 감소경향을 보였다. 간 조직 microsomal 및 mitochondria 분획에서도 같은 경향이 관찰되었다. 이때 간 조직 중의 글루타티온 농도는 정상군 보다 알코올 투여 대조군에서 5%수준에서 유의적으로 감소하였으며, 이러한 감소는 GYE 투여에 의해 더욱 감소되었으나 FF-8GY 투여에 의해서 정상군 수준까지 회복되는 것으로 나타났다. 한편 간조직의 손상정도를 나타내는 또 하나의 지표인 혈청 총단백질 및 알부민 농도는 알코올 처리 대조군에서 낮게 나타난 반면 FF-8GY 투여에 의해 정상군 수준 이상으로 증가하는 것으로 나타났다. 이상의 결과에서 글루타티온 고함유 효모 Saccharomyces cerevisiae FF-8 균체(FF-8GY)의 투여에 따른 알코올성 유발 산화스트레스의 경감 효과는 시판되고 있는 글루타티온 고함유 효모 추출물 보다 더욱 현저한 개선 효과가 있는 것으로 확인되었다.

본 연구는 발효울금 추출물에서 알코올로 유발된 산화적 스트레스에 대한 간세포 손상에 대한 보호 효과를 평가하기 위해 발효울금을 열수 추출, 냉수 추출, 80% 에탄올 추출 및 메탄올 추출하여 HepG2/2E1 세포에서 알코올과 추출물을 함께 처리 후 세포생존율을 평가하고 세포생존율이 가장 높은 냉수 추출물에서 reactive oxygen species(ROS) 함량, 항산화 지표와 malondialdehyde(MDA) 함량을 측정하였다. 알코올에 대한 간 보호 효과에서는 알코올만 처리한 군의 세포생존율이 72.8%로 감소하였으나 발효울금 냉수 추출물을 함께 처리 시에 세포생존율이 86.1%로 유의적으로 증가하며 간 보호 효과를 확인하였다. 또한, 발효울금 냉수 추출물에서 세포 내 ROS 생성 억제능은 에탄올만 처리한 군에서 무처리군에 비해 유의적으로 ROS 생성이 증가하였으나 발효울금 냉수 추출물 $100{\mu}g/mL$, $250{\mu}g/mL$, $500{\mu}g/mL$ 농도 처리군 모두 알코올만 처리한 군과 비교 시 유의적인 차이를 보이며 ROS level을 감소시켰다. 항산화 지표에서 효소적 항산화인 catalase, glutathione-S-transferase, superoxide dismutase, glutathione peroxidase 및 glutathione reductase는 알코올만 처리한 군에서 무처리군보다 감소하였으나 발효울금 냉수 추출물 $500{\mu}g/mL$ 농도 처리군에서는 알코올만 처리한 군에 비해 유의적인 차이를 보이며 항산화 효소의 감소를 억제하였다. GSH 함량은 에탄올만 처리한 군에서 무처리군보다 유의적으로 함량이 감소하였으나 발효울금 냉수 추출물 $250{\mu}g/mL$, $500{\mu}g/mL$ 농도 처리군 모두 에탄올만 처리한 군에 비해 GSH 함량의 감소를 억제하였다. MDA 함량은 알코올만 처리한 군에서 무처리군에 비해 유의적으로 증가하였으나 발효울금 냉수 추출물 고농도 처리군($500{\mu}g/mL$)에서는 알코올만 처리한 군에 비해 유의적인 차이를 보이며 MDA 함량을 감소시켰다. 이상의 결과로부터 발효울금 추출물 중 냉수 추출물에서 알코올성 간 손상에 대한 간 보호 효과가 높게 나타나는 것을 확인하였다. 결과적으로 본 연구를 통해 발효울금을 냉수 추출하는 것은 발효울금의 알코올성 간 손상에 대한 간 보호 효과를 증대시키고 ROS 생성을 억제, 항산화 효소와 GSH 함량의 감소 억제 및 MDA 함량의 증가 억제 효과를 높이는 것으로 확인되었다. 이에 발효울금을 냉수로 처리하여 추출하는 것이 간 보호 효과를 증대시킬 수 있는 효과적인 방법이며, 이러한 방법을 통해 얻은 발효울금 냉수 추출물은 알코올로 유발된 산화적 스트레스에 대한 간세포 손상에 대한 보호 효과가 있는 기능성 소재로 활용될 수 있을 것으로 생각한다.

Nuruk contributes to the unique characteristics of Korean alcoholic beverages. In this study, the effects of nuruk extracts (NE) on anti-oxidant characters, melanogenesis, and anti-photoaging activity were investigated. NEs were obtained from the 70% ethanol extracts of six types of nuruk, which have been used in brewing of fermented alcohol beverages in Korea. First, various antioxidant characteristics were identified in terms of 2,2'-azino-bis(3-ethylbenzthiozoline-6-sulphonic acid) (ABTS) radical scavenging activity, superoxide dismutase (SOD) expression, and inhibition of xanthine oxidase activity. NE#4 exhibited potent ABTS radical scavenging activity ($IC_{50}$ = 19.51 ${\mu}g$/mL). Compared with NE#4, relatively lower levels of activity were observed for NE#3 and NE#6, with $IC_{50}$ values of 90.99 and 76.88 ${\mu}g$/mL, respectively. According to results of western blot analysis for determination of SOD expression in $H_2O_2$-treated HepG2 cells, NE#5 and NE#6 induced a dramatic increase in the expression ratio of SOD, compared to the group treated with $H_2O_2$ only. Activity of xanthine oxidase, which converts xanthine into uric acid, generating superoxide ions, was inhibited by NE#4 and NE#6 in a dose-dependent manner. NE#4 induced significant inhibition of mushroom tyrosinase activity. A reduction in cellular melanin contents of 80% was observed in B16F1 melanocytes treated with NE#5 and NE#6; these effects were similar to those of arbutin at 100 ${\mu}M$. In addition, gelatin zymography and reverse transcription-PCR analysis were performed for assessment of anti-photoaging activity of Nuruk. Treatment with NE#6 resulted in dramatically inhibited activities of matrix metalloproteinase (MMP)-2/-9, suppressed expression of MMP-1, and increased expression of type-1 procollagen. Results of gelatin zymography for NE#4 and NE#5 were similar, to a slightly lesser degree. These results suggest the potential of NE#4 and NE#6 as natural ingredients for use in functional foods and cosmetics.

The purpose of this study was to analyze variables associated with smoking and selected health behaviors. This study targeted adult men and women over 20 of age. The sample population was drawn from the national sample, and the samples were chosen from the telephone book. A total of 1,500 cases were collected through a telephone based interview survey. As a tool for this study, a structured questionnaire was developed. the variables included self-perceived health status, and selected 7 health behaviors; smoking behavior, physical activities, eating habit, weight control, alcohol consumption, stress management, and cancer exam. The healthy life practice actions of Trans-theoretical model have been classified into five stages. Smokers were more likely than non-smokers to positive attitudes toward smoking and the impact of smoking in this study. This means that smokers's awareness toward the impact of smoking is very week. Smoking behavior was significantly related to other health related behaviors based on the correlation analysis. However, gender, engaging in regular physical activities, moderate consumption of alcoholic beverages, and receiving a cancer examination were the variables that can explain and predict a person's stages of adopting a non-smoking behavior. Self perceived health status was closely related to other health behaviors. Gender, age, and monthly household income were important demographic variables that have significant relationship with the self-perceived health status. Among the health behaviors, regular physical activities and weight control were significant predictable variables. Similar results have been found in the National health and Nutrition examination survey in Korea. As a result of this study, it was found that among the selected health behaviors, engaging in physical activity was an important variable to increase positive sense of health and non-smoking behaviors. Educational and policy level input is needed to increase awareness and provide chances to participate in fitness activities. To those who maintain exercise, the environmental support and diffusion of knowledge information and education data should be strengthened. To change attitudes toward smoking, more in-dept awareness campaign and education should be provided according to people's different behavioral status. In addition, not only diffusing health education data and delivering knowledge information through related programs, but also environmental support system that helps an individual maintain his/her action is required. Such a support system means settlement of the health enhancement base of school, workplace and community should be carried out, and the policy level support and regular programs should be provided and spread to the unit of community.

Sasa (S.) quelpaertensis Nakai (Korean name, Jeju-Joritdae), which has anti-oxidative and anti-inflammatory activities, is a type of bamboo grass distributed widely in Jeju Island, Korea. S. quelpaertensis leaves are used for therapeutic purposes in traditional Korean medicine. This study examined the hepatoprotective effects of the S. quelpaertensis ethyl acetate fraction (SQEA) in a mouse model to mimic alcoholic liver damage. The mice were administered orally with 30% alcohol (5 g/kg) once per day with or without SQEA treatments (100 and 200 mg/kg) for 14 days consecutively. Alcohol consumption increased the serum alcohol content and histopathological changes but reduced the liver weight. Moreover, the livers of the alcohol group exhibited the accumulation of malondialdehyde and cytochrome P450 2E1 (CYP2E1), and lipid droplet coating protein perilipin-2. On the other hand, SQEA dose-dependently attenuated the alcohol-induced serum ethanol content and liver histopathological changes but increased the liver weight. Moreover, SQEA attenuated the level of CYP2E1 and inhibited alcohol-induced lipogenesis in the liver via decreased perilipin-2 expression. These results suggest that SQEA can provide a potent way to reduce the liver damage caused by alcohol consumption.

This study examined the cultural dietary habits as well as attitudes toward food, within other life pattern elements, of students living in Gwangju City and Chonnam Province, Korea. Questionnaires from 1,000 student respondents were analyzed. The survey consisted of questions regarding physical condition and health status, dietary consciousness, food preference, knowledge of food and nutrition, and dietary culture. The results showed that 1.6% of the students considered their own physical condition to be extremely poor, and 2.7% and 2.1% also considered their father's and mother's physical conditions as extremely poor, respectively. Among the respondents, 18.3% were smokers and consumed an average of 14.8 cigarettes per day. With regard to their dietary habits, the students answered that they preferred to eat meals with friends rather than with family members, fruit was chosen for eating over health food supplements, and there was very little participation or interest in various food and cultural festivals. The female students had a tendency to alleviate mental stresses by eating, while the male students performed more physical activity to deal with stress. The female students also preferred cereal, fruit, fast food, and sweetened foods more than the male students. Between the smokers and non-smokers, significantly more non-smokers chose fruit (p<0.01), ethnic foods (p<0.05), and sweetened foods (p<0.05) as compared to the smokers. Body mass index (BMI) had significant positive correlations with soft drink (p<0.01), health food supplement (p<0.01), and alcoholic beverage (p<0.001) consumption, while BMI was negatively correlated with cereal (p<0.01), fruit (p<0.001), and sweetened food (p<0.01) intake. The health status of students was positively correlated with their father's health status (p<0.01), mother's health status (p<0.001), and BMI (p<0.05), as well as cereal (p<0.001), high protein side dish (p<0.01), fruit (p<0.01), vegetable (p<0.01), and traditional food (p<0.001) intake. The average body weight for female students was approximately 5 kg less than the Korean Nutrition Society's standardized weight, therefore, it is strongly recommended that measures be taken to develop a systematic nutrition education program that would help those students who often unintentionally skip breakfast or go on extreme diets to improve body image.

This research, aiming at analyzing the Emergency Medical Technicians' duties prior to establishing a baseline for question development in the national exams to qualify for the EMTs, investigated the importance and frequency per unit specified in the description with the EMTs to be subjects working on the task spot by means of questionnaires. The EMT duties were classified into 9 items like 1) the notification and response, 2) the scene size-up, 3) the patient assessment, 4) the emergency care, 5) the patient transport, 6) the duties at hospital clinics, 7) the operational management, 8) the receiving and responding to a call, 9) the self-development, and put the functional tasks into 52 items, describing the task elements into 177 items, and then questioned 112 EMTs working on the spot from July 21 through August 30, 2000, which showed the following results. 1) The distribution of subjects' career showed the highest rate with 33.9% for those who careered "less than a year", only 13.4% for those with more than 4 years and the highest rate with 43.8% for those who aged at 20-25. And 70.5% of all those who were questioned was the junior college graduates, 58.9% for those working at fire station and 29.5% working at hospital clinics. 2) Looking at the distribution of frequency and importance for each task element, questioning 'the patients main symptoms', 'accidental type', 'place of the patients identification' showed the highest rate in both frequency and importance in the field of "notification and response". 3) In the "scene size-up", identifying the patients showed the highest rate of frequency and importance, compared to other field of tasks, among which "identifying the patients' state" showed the highest rate of frequency (2.66) and importance (2.81). 4) In the "patient assessment", "identifying the patients" showed the high rate of frequency and importance in most elements of task, especially the importance showed the highest rate with 2.83 for the task of airway management and the cervical immobilization during "the primary assessment", and the frequency showed the highest rate for questioning the past case of the task of grasping the patients' history. 5) In the "emergency care", "the management of the heart attacked patients" and "the advanced cardiac life support" showed a high rate in the importance, whereas the frequency showed a very low rate. The high rate of frequency during the emergent task was the management of "musculoskeletal system injury patients" and of "the gastro-intestinal and urinary genital system injury patient support." In care of the patients with heart attack, the management of the airway showed the highest rate with 2.95, whereas the management of alcoholic abused patients and of dying patients, showed comparatively lower rate of assessment in the importance. The frequency of tasks showed the highest rate with 2.69 in the control of bleeding and the lowest with 0.47 in the management of abnormal delivery of child. 6) As to the patient transport, "the emergency transport" showed the highest rate with 2.74 and the unemergent transport with 2.55 in the importance, and the task importance at hospital showed the highest rate with 2.89 in managing the cardio-pulmonary resuscitation and with 2.60 in identifying the patient state. 7) Of all the tasks related with "operational task", the high importance was to "educate for the management of the first responder", but the frequency of tasks mostly showed a low rate and "receiving and responding to a call" showed relatively a high rate of importance and frequency. And related with "the self-development", "the health care management" and "the stress control" on working spot showed a high rate, but the frequency mostly showed a low rate.
