Background: Socioeconomic status (SES) is closely associated with health outcomes, including mortality in critically ill patients admitted to intensive care unit (ICU). However, research regarding this issue is lacking, especially in countries where the National Health Insurance System is mainly responsible for health care. This study aimed to investigate how the SES of ICU patients in South Korea is associated with mortality. Methods: This was a retrospective observational study of adult patients aged ${\geq}20$ years admitted to ICU. Associations between SES-related factors recorded at the time of ICU admission and 30-day and 1-year mortalities were analyzed using univariable and multivariable Cox regression analyses. Results: A total of 6,008 patients were included. Of these, 394 (6.6%) died within 30 days of ICU admission, and 1,125 (18.7%) died within 1 year. Multivariable Cox regression analysis found no significant associations between 30-day mortality after ICU admission and SES factors (P>0.05). However, occupation was significantly associated with 1-year mortality after ICU admission. Conclusions: Our study shows that 30-day mortality after ICU admission is not associated with SES in the National Health Insurance coverage setting. However, occupation was associated with 1-year mortality after ICU admission.

Objectives: An epidemiological investigation was requested for a worker who developed COPD and IPF after long-term molding and firing at a domestic tile manufacturing site. We would like to share the results of the exposure assessment and the estimation of past work. Methods: The content of crystalline silica in four raw materials was analyzed, and the respirable fraction of crystalline silica and dust generated in the air from molding and firing workers and other processes were measured. The measurement and analysis method referred to the NIOSH method. Results: The crystalline silica content of the raw material was 24~47%. The concentration of crystalline silica in the molding and firing process workers and the surrounding area was at the level of the exposure standards set by the Ministry of Employment and Labor and ACGIH, and the respirable and total dust exposure levels were generally low. The crystalline silica concentration of the area samples measured to estimate past work was about twice as high as the exposure standard of the Ministry of Employment and Labor (0.05 mg/m3), and the exposure levels of respirable dust were also quite high at 0.903 and 1.332 mg/m3. Conclusions: It was confirmed that tile molding and firing workers are currently exposed to a fairly high level of crystalline silica, and a high level is also confirmed in area samples to estimate past work. In the past, it is judged that the level of exposure would have been much higher due to differences in production volume, working method, presence/absence of local ventilation facilities, and process layout. When working in such a working environment for a long time, respiratory diseases such as lung cancer, COPD, and IPF can occur.

이 글에서는 2000년대 중반 이후 한국의 임금불평등을 지니계수의 변화와 이를 초래한 요인들의 기여도를 분석하였다. 자료와 임금 지표에 따라 추세가 달라지지만, 주당 35시간 미만 일하는 파트타임의 증가로 전체근로자 임금총액의 지니계수는 증가하는 추세를 보여주는 반면, 시간당임금 지니계수와 풀타임근로자의 임금총액 지니계수는 하락하는 추세를 나타냈다. 파트타임 증가가 임금총액 기준의 불평등은 높였지만, 파트타임의 시간당임금 증가는 시간당임금 기준의 불평등을 낮추었다. 풀타임 노동자만을 대상으로, 지니계수 감소 요인을 분해한 결과, 불평등 감소에 절대적으로 기여가 큰 요인은 근속, 경력, 직종 등의 변수였고, 고용형태 변수는 불평등 감소에 미미하게 기여하는 것으로, 사업체 규모 변수는 불평등을 오히려 높이는 것으로 나타났다. 업종이나 연령, 교육 등의 변수는 불평등 변화에 유의미한 크기의 기여를 하지 못한 것으로 분석되었다. 여기에는 장기근속과 관리전문직종에 대한 임금프리미엄의 감소와 대규모사업체의 임금프리미엄 증가 등이 작용한 것으로 분석되었다.

Objectives: In this study, we assessed respiratory hazards in the working environment as the work-relatedness of occupational diseases were examined. Methods: The subjects of the study were three Korean meat roasting restaurants, one Chinese restaurant, and two cafeterias. Measurement items were total dust, respirable dust, fine dust (PM_2.5), PAHs, TVOCs, temperature, humidity, carbon monoxide, carbon dioxide, and nitrogen dioxide. Results: The concentration of total dust and respiratory dust in the restaurant was low. Most PAHs were undetectable, but some Napthalene and Acenaphthylene was detected. Thirteen kinds of PAHs were detected in one sample of roasted meat, and Benzo(a)pyrene was 1.496 ㎍/㎥. PM_2.5, TVOCs, CO, and CO₂ were instantaneously high, but the average concentration was low. NO₂ was not detected. Conclusions: The results show that harmful substances such as PM_2.5, PAHs, CO, and TVOCs were generated in the air in the catering industry. When roasting meat, Benzo(a)pyrene, a carcinogen related to lung cancer, was generated among PAHs. Lung cancer can occur when working for a long time in such a working environment. Therefore, it is necessary to improve the working environment for the health of restaurant workers, and it is necessary to evaluate the concentration of harmful substances by cooking method through further research.

Background: Arthroscopic surgical repair is a better intervention than non-operative (conservative) treatment for patients with shoulder dislocations. This systematic review determined the numbers-needed-to-treat (NNT) and relative risk reduction (RRR) associated with arthroscopic surgical repair versus non-operative treatment in reducing recurrence rates among patients with first-time traumatic anterior shoulder dislocations. Methods: We searched Google Scholar, MEDLINE, SPORTDiscus, and CINAHL from inception in 2015. All articles had to compare arthroscopic surgical repair and non-operative treatment and be written in English. We used the total number of subjects and the number of recurrent dislocations within each treatment to calculate the NNT and RRR for each study and the pooled data. Results: Six articles were selected and all clearly demonstrated that the arthroscopic surgical repair was more effective than non-operative treatment in reducing the recurrence episodes. The pooled NNT was 1.76 (95% confidence interval [CI]=NNT to benefit 1.50-2.13) and the pooled RRR was 86.0% (95% CI=77.0%-92.0%) among individuals who underwent arthroscopic repair. The average follow-up time was 56 months. Conclusions: A Strength of Recommendation Taxonomy level of evidence of 1 with a grade A recommendation supports the use of arthroscopic surgical repair over non-operative treatment in prevention of first-time traumatic anterior shoulder dislocations. We suggest that sports medicine practitioners consider the patients' age, occupation, and physical activity level when making a clinical decision.

This study attemps to identify the factors related to dealing withy work-family conflict of employed women, and to investigate the needs and the methods of support for household labor. Especially, the results of this study aims to be reflected in women's policy from a political point of view. For these purposes, 477 married women those being employed (more than 30 hours per week) and having nuclear family were selected. Statistics were frequencies, means, percentile, and two-way ANOVA. The results were as follows. First, employed mother's housework time is 5 hours 16 minutes on a weekday and 9 hours 32 minutes on Sunday with the exception of market work time. And 84.5% of total housework was performed by housewife. Thus they take chage of work burden(market work and housework), and make a difficulties of cooking and family care. Seconds, the highest needs of support was the change of thought on division of labor, responsibility on housework, and status of women. The next were the needs of the social organization(flex-time, a special holiday for woman workers, home-based work) and the public institution(day-care center, school feeding). Thirds, contributing factors to the needs of support were housewife's age and occupation. So, this two factors were crossed in order to analyze family type by factors.
