Background: Cancer imposes significant economic challenges for individuals, families, and society. Households of cancer patients often experience income loss due to change in job status and/or excessive medical expenses. Thus, we examined whether changes in economic status for such households is affected by catastrophic health expenditures. Materials and Methods: We used the Korea Health Panel Survey (KHPS) Panel $1^{st}-4^{th}$ (2008-2011 subjects) data and extracted records from 211 out of 5,332 households in the database for this study. To identify factors associated with catastrophic health expenditures and, in particular, to examine the relationship between change in economic status and catastrophic health expenditures, we conducted a generalized linear model analysis. Results: Among 211 households with cancer patients, 84 (39.8%) experienced catastrophic health expenditures, while 127 (40.2%) did not show evidence of catastrophic medical costs. If a change in economic status results from a change in job status for head of household (job loss), these households are more likely to incur catastrophic health expenditure than households who have not experienced a change in job status (odds ratios (ORs)=2.17, 2.63, respectively). A comparison between households with a newly-diagnosed patient versus households with patients having lived with cancer for one or two years, showed the longer patients had cancer, the more likely their households incurred catastrophic medical costs (OR=1.78, 1.36, respectively). Conclusions: Change in economic status of households in which the cancer patient was the head of household was associated with a greater likelihood that the household would incur catastrophic health costs. It is imperative that the Korean government connect health and labor policies in order to develop economic programs to assist households with cancer patients.

The present study reports on the results of a risk survey of machinery safety at a shoe factory in Qingdao, China. The aim is to decrease industrial accidents and increase worker job satisfaction by searching for a change from a trend analysis and making improvements in problem areas. The first risk survey for machinery safety was carried out in April 2005. Based on the analysis of the survey results, machinery safety devices was installed in the factory by using CATlA V5. Also, we investigated job satisfaction concerning working apparatus and work tool improvement in a questionnaire about the working environment. The second survey of machinery safety was carried out in September 2005. We are in the process of comparing the first survey results with the second survey results in order to analyze decreasing trend in industrial accidents and improvement in job satisfaction. So far the data have shown improved short-term turnover and absenteeism. It means CATIVA V5 and CFR has had positive effect regarding safety in shoe manufacture industry. The survey with CATIVA V5 and CFR will be expanded to other East-Asian countries including Vietnam. The hope is that the present approach could make a significant contribution toward improved safety.

이 논문은 한국노동패널 조사 자료를 이용하여 실직자들이 겪는 임금 손실의 정도를 실직 발생 직후에서 부터 4년 후까지 분석하였다. 종전에 국내에서 이루어진 연구들에서는 주로 실직 직후에 발생하는 손실에 초점이 맞춰졌는데, 실직으로 인한 손실이 지속될 경우 이는 손실을 과소 추정하는 것이 된다. 논문의 분석 결과에 의하면 실직 발생 4년 후에도 실직으로 인한 임금 손실이 유의미하게 지속되는 것으로 나타났으며, 이는 실직으로 인해 발생하는 일자리 경험의 손실과 반복 실직의 발생에 크게 영향 받은 결과인 것으로 나타났다.

본 논문은 몸이 아픈데도 불구하고 출근을 하는 행위를 뜻하는 프리젠티즘(presenteeism) 과 연관되어 있는 직업 환경적 요소들을 탐색하고자 하는데 목적이 있다. 프리젠티즘은 학술연구 분야에서 상대적으로 새로운 개념이지만, 노동자들의 미래의 직업적 전망과 삶의 질에 위협을 가하는 중요한 요인이자, 노동생산성을 저하시킨다는 의미에서 중요한 사회적 이슈가 된다. 이 연구를 위해 안전보건공단에서 실시하는 근로환경조사 2014년 자료가 사용되었고, 분석에는 15세 이상의 임금근로자 24,571 명이 포함되었다. 프리젠티즘의 경험 여부에 대한 로지스틱 분석을 시행하여 노동시간과 개인생활, 노동환경과 직장환경, 고용불안정, 보상과 복지 네 가지 측면에서의 가설을 검증하였다. 분석 결과로부터 1) 근무시간으로 인해 가족/사회생활의 어려움이 크다고 느낄수록, 2) 노동시간압박이 크고, 직장만족도가 낮을수록, 3) 직업불안정성이 클수록, 4) 복지 수준이 낮을수록 프리젠티즘의 가능성이 높다는 점이 확인되었다. 이는 직장의 업무요구나 직업적 환경이 개인의 주관적 기대수준과 부조화가 나타나 개인적 자원의 손실이 예상될 경우, 건강상태가 좋지 않음에도 불구하고 출근을 하여 그 손실을 메우고자 한다는 본 논문의 이론적 논의와 일관된 결과라 볼 수 있다. 프리젠티즘은 노동자 개인의 삶의 질과 건강에 부정적인 영향을 줄 뿐만 아니라 사회적 비용도 발생시키는 관행인 만큼, 조직적인 측면에서 이를 예방할 수 있는 방법에 대한 모색이 필요하다.

Changes in viscosity and dynamic theological properties of Job's-tears were measured by Bohlin dynamic tester as a function of moisture, and measurement was performed within a linear viscoelastic range. The result of the shear stress vs shear rate of Job's-tears at different moisture contents $(50{\sim}75%)$ was applied to mathematical models and Herschel-Bulkley model showed the highest correlation coefficient. Lower moisture content (55%) produced higher yield stress and consistency index, but lower flow behavior index, whereas higher moisture content showed reverse effects. Job's-tears with $50{\sim}70%$ moisture contents showed a higher storage modulus (G') than loss modulus (G') at all frequencies, showing a higher concentrated polymer characteristics. However, higher moisture content (>75%) showed crossover point between G' and G', and frequency dependency. As the moisture content was increased, the amount of viscoelastic properties such as G', G', complex viscosity decreased during heating, and initial temperature and miximum value of viscoelastic properties shifted to higher temperatures, representing the moisture-dependence of Job's-tears upon theological properties.

Purpose: The purpose of this study was to investigate the relationship between subjective quality of life and job stress with regard to general characteristics and health characteristics of physical therapists (PTs) and occupational therapists (OTs). Methods: The study involved administering questionnaires to 93 PTs and OTs who worked in urban medical institutions between November 2009 and October 2009. A questionnaire (KvSBQOL) developed by Dunbar and colleagues and translated into Korean version by Yoon et al was used for measuring subjective quality of life. A questionnaire developed by Kim was used for measuring job stress. Results: Among PTs and OTs, the mean quality of life score was 3.10 points and the mean level of job stress was 3.42. Female PTs and OTs had significantly greater levels of job stress. Those PTs and OTs in the 'Lowest pay' group and in the 'Associated Degree' group reported the lowest quality of life. Those in the 'Very healthy' group of PTs and OTs had significantly lower job stress than the other groups. The group with the highest job stress had the lowest quality of life. A limitation of this study was that all data was self-reported and subject to associated bias. Conclusion: To prevent loss of business services by PTs and OTs, it is important to know how job stress affects quality of life. Our findings suggest that a reduction in job stress can improve quality of life among PTs and OTs.

Background: Nursing home resident care is an ongoing topic of public discussion, and there is great interest in improving the quality of resident care. This study investigated the association between nursing home employees' job satisfaction and residents' satisfaction with care and medical outcomes. Methods: Employee and resident satisfaction were measured by questionnaire in 175 skilled nursing facilities in the eastern United States from 2005 to 2009. Facility-level data on residents' pressure ulcers, medically unexplained weight loss, and falls were obtained from the Centers for Medicare and Medicaid Services Long-Term Care Minimum Data Set. The association between employee satisfaction and resident satisfaction was examined with multiple and multilevel linear regression. Associations between employee satisfaction and the rates of pressure ulcers, weight loss, and falls were examined with simple and multilevel Poisson regression. Results: A 1-point increase in overall employee satisfaction was associated with an increase of 17.4 points (scale 0-100) in the satisfaction of residents and family members (p < 0.0001) and a 19% decrease in the incidence of resident falls, weight loss, and pressure ulcers combined (p < 0.0001), after adjusting for staffing ratio and percentage of resident-days paid by Medicaid. Conclusion: Job satisfaction of nursing home employees is associated with lower rates of resident injuries and higher resident satisfaction with care. A supportive work environment may help increase quality of care in the nation's nursing homes.
