Present study investigated the differences in psychological tests responses between chronic motor tic disorder and tourette's disorder to clarify whether chronic motor tic and tourette's disorder constitute a single disorder on a continuum or not. Based on the diagnosis by child psychiatrists 29 chronic motor tic disorder and 10 tourette's disorder children between the age of 6 to 13 were selected, and the psychological tests responses of two diagnostic groups were compared. The results showed that tourette's disorder is more related to neulological problems than chronic motor tic disorder. Also it was found that children with tourette's disorder have more difficulties in social-emotional adjustment than children with chronic motor tic disorder. These results suggested that interactions among neurological factor, emotional factor and temperamental characristics might be more involved in tourette's disorder than in chronic motor tic disorder. The limitations of present study and the need for futher research on the comorbidity of tourette's disorder and ADHD were discussed.

Objectives : The authors purposed to present data for explaining gene-environmental interaction causing depressive disorder by examining the effects of genetic factors related to the serotonin system and environmental factors such as stressful life events in early adulthood. Methods : The subjects were 150 young adults(mean age 25.0${\pm}$0.54), a part of 534 freshmen who had completed the previous study of genotyping of TPH1 gene. We assessed characteristics of life events, depression and anxiety scale and checked if they had a depressive disorder with DSM-IV SCID interview. Along with TPH1 A218C genotype confirmed in previous study, TPH2 -1463G/A and 5HTR2A -1438A/G genes were genotyped using the SNaPshot$^{TM}$ method. Results : In comparison with the group without C allele of TPH1 gene, the number of life events had a significant effect on the probability of depressive disorder in the group with C allele. Other alleles or genotypes did not have a significant effect on the causality of life events and depressive disorder. Conclusion : The results of this study suggest that TPH1 C allele is a significant predictor of onset of depressive disorder following environmental stress. It means that the TPH1 gene may affect the gene-environmental interaction of depressive disorder.

American Psychiatric Association defined hwa-byung as a unique mental illness of Korea, a kind of anger syndrome. This illness caused by the Korean culture is more often found on women than men, especially middle-aged women. The cause of hwa-byung mainly depends on the traditional family structure of Korea formed by Confucianism. Other causes that many middle-aged women suffer from hwa-byung are that their low education level originated in their wrong-recognized position in society and poverty in the past makes them not to be able to control their minds effectively(social psychological factor), and that they get stressed and depressed because of loss of their position in the family after their children leave home and the menopause which hurts their feminine beauty (physiological factor). So, this program aims at letting them to; 1) experience catharsis of the negative feelings which causes hwa-byung by expressing in psychodrama, 2) ease the symptoms of hwa-byung by relaxing their mind, 3) understand themselves through sharing their feelings and thinking at the group level, 4) acquire the opportunities to stabilize and expand their role in their real lives through the role playing.

As the nature of triathlons is competition in three successive sports, triathletes experience elevated levels of stress on the body that are absent in single-sport athletic events, and consequently there are more potential medical problems to prepare for. Triathletes can also experience problems such as hypothermia, heat illness, excessive exposure to ultraviolet radiation, musculoskeletal injuries and trauma, immunosuppression, and haemolysis. Depending on the potentiality of such above-listed problems occurring in any given race, race organizers will prepare preventative measures and treatments accordingly. Olympic distance is not the only triathlon racing distance. Sprints, which are normally around half the Olympic distance, are common distances, as well as Long (2 km swim, 80 km bike, 20 km run), Ironman (3.8 km swim, 180 km bike, 42 km run), and ultra-distance events varying in length. Races of longer duration normally result in a higher percentage of athletes experiencing the above-mentioned medical problems, as well as inducing additional health risks such as hyponatraemia. Minimizing the occurrences of serious health issues is possible through the following means: carefully preparing for the probable race-day weather conditions; proper management and organization of the race; preparing an extensive water-safety and ground-course safety plan; distributing necessary nutrition along the course; and stressing the importance for athletes to have proper knowledge concerning race nutrition, biomechanical technique, physical preparation, and utilization of safe equipment. While risks of competing in triathlon are many, the instances of such medical problems are not excessive, and the triathlon has a reputation of being a reasonably safe sport as long as athletes with high risk take added precautions.

우리 사회에서 일정 정도 이상의 사회와 가정에서의 기능상의 부적응을 초래하는 정신적 문제는 경제활동인구에 있어 가장 흔한 보건의료상의 문제일 것으로 추측되고 있으나, 현재까지는 정신보건제도 마련에 있어 가장 극심한 부적응을 보이는 정신적 장애를 지닌 환자를 위주로 수용시설과 지역사회에서의 재활과 관리에 그 초점을 두어 왔다. 즉 직업스트레스와 같은 일시적인 사회심리적 갈등으로 인한 신체증상의 호소나 알을 및 약물중독으로 인한 사고의 발생으로부터 일생동안 관리되어야 하는 지능저하나 학습장애와 같은 만성적인 문제에 이르기까지 다양한 스펙트럼을 보이는 사업장과 지역사회에서의 정신적 문제들 중 그 일부만이 제도적으로 관리되어 왔다. 실제 그 동안 직장 내 정신보건문제에 대한 행정적 관심은 일부 장애인의 취업 문제를 제외하고는 없었다고 하여야 할 것이다. 그러나 한편으로 우리 사회의 산업구조와 경제사회적 조건의 변화에 따른 노동내용과 조건상 유연화의 증대가 많은 직장에서 노동강화로 이어진다는 점, 그리고 가족 및 교류집단을 비롯한 전통적인 사회적 지지구조가 와해되고 있다는 점과 정신적 문제로 인한 기능상 부적응의 척도가 한편으로 사회적 가치관의 변화에 따라 계속 그 영역이 넓어지는 방향으로 변화하고 있다는 점등에서 직장 내 정신보건 문제는 앞으로 더욱 그 비중이 커질 것으로 판단되고 있다. 문제의 심각성에 대한 관심이 요구되는 현재의 시점에서 제도적 접근에 대한 검토 또한 시작되어야 할 것으로 판단되고 있다. 현재까지 기업 내에서 이루어지고 있는 정신보건관리의 현황을 단편적으로 파악해 보았을 때, 단지 일부 기업에서 취업시 내지는 부서 배치시 성격검사를 비롯하여 적성검사를 실시하고 있으며, 기업윤리확보 차원에서 비정규적으로 사기앙양을 주목적으로 하는 집단적인 교육이나 단체훈련이 이루어지고 있으나, 정신심리적 문제를 개인적 차원에서 그리고 또한 조직적 차원에서 체계화된 프로그램으로 관리하고 있는 사례는 아직 없다. 앞으로 직장 내 정신보건문제에 대하여 제도적인 접근을 하기 위하여서는 다음과 같은 세가지 조건들이 구비되어야 할 것으로 판단된다. 첫 번째로 문제점 그 자체의 내용과 그 규모에 대한 정확한 파악과 예측이 가능하여야 한다. 즉 제도 전체의 운영을 객관적으로 평가하고 개선할 수 있는 기제가 함께 있어야 제도가 실제적인 기능을 할 수 있다는 최소한의 목적이 달성될 수 있다. 두 번째로 문제점의 관리를 위한 효과적인 개입내용 및 개입지점의 확보가 가능하여야 한다. 특히 직장 내에서 수행할 수 있는 프로그램이 개발되어야 하며, 이는 시범사업과 시장을 통한 소비자, 즉 사업주들의 자발적인 선택을 통하여 검토되고 걸려져야만 한다. 마지막으로 제도 운영의 대상, 특히 정신보건문제를 안고 있는 노동자들의 자발적인 동의가 확보될 수 있어야 한다. 이는 정신적 문제가 안고 있는 편견과 그로 인한 차별이 가져다주는 문제를 함께 고려하면서 제도가 운영되어야 하며, 이에 있어 제도 운영상 노동자들의 주체적인 참여가 필요하기 때문이다. 이상 고려되는 직장 내 정신보건문제에 대한 제도적 접근을 담기 위하여서는 프로그램 개발이나 전문가 집단의 양성과 같은 단순한 기술적 접근과 이들의 인허가 및 사업화에 따른 적용기준 및 의무의 설정과 같은 제도적 접근에 그쳐서는 그 실효성을 담보하지 못할 것으로 판단된다. 보다 중요한 것은 이러한 정신보건문제에 대한 노사의 공감대를 이루어 내는 것이며, 사회 전반적인 인식의 확산과 더불어 바람직한 관리모습에 대한 사회적 가치관을 도출해 내는 것이 제도적인 접근의 성공을 보장할 수 있는 기반 조건이 될 것이다. 이러한 점에 있어 정신보건문제를 바라보는 기존의 가치관이 부정적이고 고착화된 모습만을 강조하였으나, 이제는 점차 긍정적이 사회활동에 수반되는 역동적인 모습으로서 비추어지는 것이 많아진다는 측면에서 그 전망을 밝게 하여 주고 있다.

Stress is a primary health promotion issue in worksite research because psychological distress is closely related not only to workers' health status but also to their job performance. This study identified the significant health behaviors affecting workers' job-related stress in Korean manufacturing industry with the national survey data conducted by the Korean Occupational Safety and Health Agency in 2003. A total of 7,818 factory workers in 1,562 manufacturing companies participated in the Korean nation-wide occupational health survey and 3,390 workers answered that they had any stressors in their workplace among the 7,818 workers finally participated in the analysis. Participants were selected by the stratified proportional sampling process by manufacturing industry classification, company size, and company locations (8 metropolitan and 8 non-metropolitan regions) in Korea. Trained interviewers visited the target companies and interviewed the factory workers randomly selected in each company. Smoking, drinking, weight control, exercise, sleeping, break time at work, and perceived fatigue were included in the health behavior construct. Stress symptoms was consisted of physical and psychological stress with 8 items. All survey responses were anonymously coded into the SPSS statistical program and testified using stepwise multiple regression analysis. Male workers were 73.5% and the 30s were 40.0% among the age groups. The married and the high school graduate were majority with 52.1% and 61.8% each. Current smokers were 44.7% and More than 50% of the participants drank alcohol sometimes. No exercise group was 59.3% and the participants who dissatisfied with their daily sleeping hours were 43.5%. In t-test and analysis of variance, the significant general characteristics associated with physical and psychological job stress were young age (p<0.001), single marital status (p<0.001), and short working period at the present company (p<0.001). The health behaviors related to physical job stress were current smoking, weight change during the past one year (p<0.001), weight control effort (p<0.001), exercise (p<0.001), daily sleeping dissatisfaction (p<0.001), break time, and perceived fatigue (p<0.001). All 10 health behavior factors were significantly associated with psychological job stress (p<0.05). Weight change, weight control effort, exercise, daily sleeping dissatisfaction, little break at work, and high perceived fatigue were significant factors affecting job stress. Daily sleeping dissatisfaction, little break at work, little exercise, weight change for the past one year and young age were selected as the significant health behavior and general factors affecting physical job stress symptoms in stepwise multiple regression analysis. The five factors explained 18.9% of the physical stress score variance. Six factors were selected as the significant health behaviors affecting psychological job stress: daily sleeping dissatisfaction, little exercise, frequent drinking alcohol, high perceived fatigue, little break at work, and little weight control effort. The six factors explained 10.6% of the psychological stress score variance.

Sessile marine bivalves including mussels, oysters and clams are often used as a sentinel species in coastal environmental monitoring since changes in the environmental quality are often well preserved in their tissues and shells. In this study, we investigated overall health condition of the Mediterranean Mussel, Mytilus galloprovincialis on the south coast using histology. Reproductive condition as gonad index (GI), condition index (CI) as a ratio of the tissue weight to the shell weight, digestive gland atrophy (DGA), types of parasites, and pathologic conditions including erosion, necrosis, hemocyte infiltration, and neoplasia were examined from each histological preparation. GI decreased from March to July then increased from July to September and spawning mussel could be observed as early as in April and the activity continued until September. CI also followed the monthly changes in GI, indicating that decrease in CI was associated with the weight loss due to spawning. DGA increased from March to June, decreased in July and increased from July to September. High DGA values observed in June and September were coincided with spawning and high water temperature. Histology also showed high prevalence of erosion in the digestive gland in June (36.0%) and September (56.4%), suggesting that high water temperature and spawning acted as environmental stressors. No parasitic organism was identified during the survey, although some symbiotic copepods were observed. Histology was found to be useful and affordable technique in monitoring the overall health of mussel, providing useful pathologic information of the cells and tissues.

Firemen are directly exposed to various harmful chemicals, physical factors and mental stress during rescue and fire-fighting. In fire extinguishing, unstable posture, poisonous gas, dust, high temperature and heavy equipments are possible hazardous factors. The alertness for emergency, shift work, job strain and stress are also possibly hazardous. Therefore, this study aimed to investigate the prevalence of musculo-skeletal symptoms and job stress and to determine risk factors in firemen. This study was carried out in a group of 226 firemen in Busan City, Korea. Standardized Nordic Questionnaire was used to investigate the prevalence of musculo-skeletal symptoms and Psycho-social Well-being Index (abbreviated PWI) was used to investigate the prevalence of job stress. General and occupational characteristics were included education, marital status, alcohol and smoking history, working duration, and work shift system. Body mass index (BMI) scores were calculated by physical examination including height and weight. Concerning musculo-skeletal complaints, the commonest site was neck, and shoulder, lower back, upper back were the next. Complaint site above one area of body was about 80%. From multiple logistic regression analysis, working duration was significant variable in musculo-skeletal symptoms. Odds ratio were 15.4 in working duration. About 16.8% was high risk stress group. From multiple logistic regression analysis, shift work and alcohol drinking were significant variables in PWI scores. Odds ratios were 2.25 in shift work. Accordingly, interventions are needed for health promotion of long term and shift worker.

In a comprehensive summary use and supplementation of some well defined natural herbal formulations in the European swine breeding and fattening is documented. Along with this data also the quality assurance, hygenic as well as the standards of efficacy of the formulations are presented. Series of experimental and development work over the last several years with universities, research institutes, veterinarians and feed industry proved that the application of such phylo-components (feed supplementation) result in to optimizing swine breeding practices. On the basis of 4 specific formulations tested and used in the European veterinary field most of the common problems of pig breeding and rearing can be successfully handled. Precisely, problems of fertility, respiration, diarrhea and stress; which are directly related to imerse losses in production, with poor quality of piglets associated with immune suppressions. Besides curing common symptoms, one of the most important aspect is of improvement in the self defence mechanism which results ultimately in to increased immunity, vitality and health of the animals; of course, thereby reducing the mortality which is the most economical problem observed in the animal health. Moreover, data presented here reflects on the fact that the use of such high quality alternative formulations successfully replace conventionally used antibiotics or hormonal therapies. They also work synergestically of as complementary in vaccination program or act as growth promoting agents on natural basis.

Objectives : The aim of this study is to review the acupoints used in cocaine studies and interpret the effectiveness in an aspect of meridian theory of Korean medicine. Methods : Authors searched 50 articles in PubMed, 16 in KISS, 9 in OASIS, 40 in NDSL, and 19 in DBPIA, with the keyword of 'cocaine' or 'acupuncture'. The articles written in English only were included. The articles related with cocaine(abuse, dependence, sensitization, intake, withdrawal sign, withdrawal syndrome, reinstatement, seeking) only were subjected. The articles which used manual- or electro-acupuncture were included, and auricular was excluded. Results : The most frequently used acupoint was HT7, while LI4, LU9, ST36, and SP6 were used once respectively. HT7 could be understood to be used from the meaning of the name as well as the theory that Heart Meridian is deeply related with the brain function. LU9 seems to be used to enhance the effect of HT7. LI4 is thought to control reverting yin that flows toward the top of head following the theory of Jang Bu Sang Tong. ST36 appears to be used because it could regulate stress reaction that reverting yin is associated with. SP6 seems to have effect on brain function due to its ability to control spiritual disorder. Conclusions : The acupoints used in the cocaine studies are thought to influence the brain function through diverse mechanism, and Jang Bu Sang Tong theory seems to be involved in the mechanism, at least in part.
