Physical activity could be considered one of the factors that affect the immune system status and function. To find the relation between exercise and cytokines, we examined the possible effects of an 8-week endurance training program on the serum levels of cytokines, including tumour necrosis factor-alpha (TNF-${\alpha}$) and interferon-gamma (IFN-${\gamma}$) in sedentary men. A total of 30 healthy young male volunteers were randomly divided into an endurance training group and a control group. The training group followed a specific exercise protocol (running on a treadmill for 15~30 min at 50~70% maximal heart rate) for 8 weeks and the control group did not participate in any exercise program. Venous blood samples were collected from both the groups 24 h before and 24 h and 48 h after the exercise. Repeated ANOVA was used for statistical purposes. The serum levels of TNF-${\alpha}$ and IFN-${\gamma}$ were determined by ELISA. Significant (p<0.05) and non-significant (p>0.05) decreases were observed in the serum levels of IFN-${\gamma}$ and TNF-${\alpha}$, respectively, after the 8-week endurance training program. Our findings indicated that an 8-week endurance exercise may affect the serum levels of some inflammatory cytokines, suggesting the beneficial role of this training protocol in elderly population and people with certain conditions (inflammation of the vertebrae or other inflammatory diseases).

Objectives: The purpose of the study was to identify a gap between consumer characteristics and utilization of health information on the Internet. Methods: A telephone survey of nationally representative samples was conducted using structured questionnaires, and 1,000 of the 1,189 responses obtained were included in our analysis. The following variables were included in the analysis as potential predictors of health information use on the Internet: predisposing factors such as gender, age, and education status; enabling factors such as region and monthly household income; consumer need for health information; and attitude to health. Multiple logistic regression analysis was used to evaluate the association between utilization rate and the potential predictors. Results: Thirty-nine percent of consumers had obtained health information on the Internet over a one-year period. The utilization rates were higher for consumers who were young, educated, worked in the office setting, had higher incomes, wanted health information, and were able to use the Internet. The utilization rate was 5.35 times higher in the younger group (20-30 years) than in the elderly group (95% CI=2.21-12.97); 2.21 times higher for office workers than for manual workers (95% CI=1.16-4.20); 3.61 times higher for college graduates than for middle school graduates and below (95% CI=1.07-11.59); 1.99 times higher for people with monthly household incomes over 3,000,000 won than for those with monthly household incomes below 1,500,000 won (95% CI=1.01-3.92). Conclusions: There needs to be a paradigm shift, with consideration of not only Internet accessibility in the digital age, but also consumer ability and attitudes toward utilization of health information.

Objective: This study aims to understand the occupational injury characteristics of the workers in the motor vehicle parts (automobile parts) manufacturing industry and to present basic guidelines on accident prevention through accident analysis. Background: There occur many occupational injuries in the motor vehicle parts manufacturing industry. But there were few researches for the occupational injuries of the workers in the motor vehicle parts manufacturing industry. Method: This study analyzed the data of occupational injuries of 1,609 workers in the motor vehicle parts manufacturing industry in 2015. The accident characteristics were analyzed by dividing them into worker related factors and accident related factors. Results: Among the occupational injuries of the workers in the motor vehicle parts manufacturing industry, 80.6% of the victims were males, 64.0% were older than 40. 57.8% of the victims were employed by the companies with less than 50 workers. In addition, there was a difference in accident characteristics according to age, work experience, employment type, events or exposures, accident time of the day, agents, natures of injuries and illnesses, injured organs and injured body part. Conclusion: It is important to prevent equipment/machinery accidents. For this purpose, more efforts should be made to establish safety measures faithful to the basics of safety devices and safety work procedures. It is also suggested that prevention of disasters should be intensively carried out for workplaces with less than 50 employees and middle-aged and elderly people. Application: The result can be used to present guidelines for preventative measures for the workers in the motor vehicle parts manufacturing industry including safety education/training.

Objectives: Several epidemiological studies on medical care utilization prior to suicide have considered the motivation of suicide, but focused on the influence of physical illnesses. Medical care expenditure in suicide completers with non-illness-related causes has not been investigated. Methods: Suicides motivated by non-illness-related factors were identified using the investigator's note from the National Police Agency, which was then linked to the Health Insurance Review and Assessment data. We investigated the medical care expenditures of cases one year prior to committing suicide and conducted a case-control study using conditional logistic regression analysis after adjusting for age, gender, area of residence, and socioeconomic status. Results: Among the 4515 suicides motivated by non-illness-related causes, medical care expenditures increased in only the last 3 months prior to suicide in the adolescent group. In the younger group, the proportion of total medical expenditure for external injuries was higher than that in the older groups. Conditional logistic regression analysis showed significant associations with being a suicide completer and having a rural residence, low socioeconomic status, and high medical care expenditure. After stratification into the four age groups, a significant positive association with medical care expenditures and being a suicide completer was found in the adolescent and young adult groups, but no significant results were found in the elderly groups for both men and women. Conclusions: Younger adults who committed suicide motivated by non-illness-related causes had a higher proportion of external injuries and more medical care expenditures than their controls did. This reinforces the notion that suicide prevention strategies for young people with suicidal risk factors are needed.

노인 인구 증가는 유럽과 미국에 걸쳐 몇 년간 관찰되어 왔지만, 일본과 한국과 같은 개발도상국에서도 증가 추세가 현저히 나타나고 있다. 개발도상국에서는 2000년, 65세 이상 노인의 인구비율이 1960년에 비해 약 5배 정도 증가했으며, 2050년에는 전체 인구의 40% 정도를 차지할 것으로 예상되고 있다. 이런 급격한 인구 변화는 이들이 특정 권리와 구매력을 지니는 새로운 사회경제적 집단으로 성장하게 하는 계기가 되었다. 노화가 일어나면, 식이요법으로 어느 정도 조절할 수 있는 인체의 변화가 다양하게 일어난다. 그 중 대표적인 것은 글루타치온 합성과 이용의 균형에 변화가 생기는 것이다. 글루타치온은 인체에서 가장 중요한 항산화 물질이고, 식이 내 시스테인 아미노산에 의해 체내 함량이 결정될 수 있다. 시스테인이 풍부한 펩티드 제품이 기능성 식품 및 식품원료로 개발되었다. 소비자 조사 결과, 이 제품은 숙면과 활력을 제공하는 등 장점이 있음이 밝혀졌다. 동물 임상 실험 결과를 통해 특별히 노인 인구를 대상으로 하여 시스테인 펩타이드의 생리 활성과 대사 과정을 소개하고자 한다.

Objectives : Socioeconomic position (SEP) refers to the socioeconomic factors that influence which position an individual or group of people will hold within the structure of a society. In this study, we provide a comprehensive review of various indicators of SEP, including education level, occupation-based SEP, income and wealth, area SEP, life-course SEP, and SEP indicators for women, elderly and youth. Methods and results : This report provides a brief theoretical background and discusses the measurement, interpretation issues, advantages and limitations associated with the use of each SEP indicator. We also describe some problems that arise when selecting SEP indicators and highlight the indicators that appear to be appropriate for health inequality research. Some practical information for use in health inequality research in South Korea is also presented. Conclusions : Investigation into the associations between various SEP indicators and health outcomes can provide a more complete understanding of mechanisms between SEP and health. The relationship between specific SEP indicators and specific health outcomes can vary by country due to the differences in the historical, socioeconomic, and cultural contexts of the SEP indicators.

Objectives : This study aimed to investigate the associations between physical disorders and prevalent/incident suicidal ideation in a community dwelling older population aged 65 years or over. Methods : 1204 people aged 65 years or over evaluated at baseline. Suicidal ideation was identified using the questions from the community version of the Geriatric Mental State Schedule ("GMS B3"). Reported physical disorders covering 11 common and generally chronic health problems were ascertained. Covariates included were depression, age, gender, years of education, accommodation status, past occupation, and current occupation. Of 1066 without suicidal ideation at baseline, 805 (76%) were followed 2 years later, and incident suicidal ideation was evaluated. Results : Prevalent suicidal ideation was significantly associated with 4 of 11 physical disorders: eyesight problems, persistent cough, heart disease and paralysis or weakness in one leg or arm. Incident suicidal ideation was associated with 3 physical disorders: asthma, high blood pressure and paralysis or weakness in one leg or arm. Both prevalent and incident suicidal ideation were significantly associated with increased number of physical disorders. Conclusions : Certain physical disorders were comorbid and precipitating factors of suicidal ideation in elders. And appropriate intervention and treatment of physical disorders might prevent suicidal ideation in elderly.
