Human resource factors associated with workplace safety and health education of small manufacturing businesses in Korea.

OBJECTIVES: Human resources (HR) are essential indicators of safety and health (SH) status, and HR can be key sources of workplace safety management such as safety and health education at work (SHEW). This study analyzed significant HR factors associated with SHEW of small manufacturing businesses in Korea. METHODS: The secondary data of the 2012 Korea Occupational Safety and Health Trend Survey were used to achieve this research purpose. A total of 2,089 supervisors or managers employed in the small manufacturing businesses completed the interview survey. Survey businesses were selected by multiple stratified sampling method based on industry code, business size, and region in Korea. The survey included workplace characteristics of HR and SHEW. RESULTS: SHEW was significantly related to business size, occupational injury incidence in the previous year, foreign and elderly worker employment, presence of site supervisors, and presence of SH committees (p <.05). SHEW for office workers, non-office workers, and newcomers was associated with business size, presence of site supervisors, and presence of SH committees in logistic regression analysis (p <.001). Businesses with 30-49 workers conducted SHEW 3.64 times more than did businesses with 5 to fewer than 10 workers. The companies that had occupational injuries in the previous year conducted SHEW 1.68 times more than the others. The businesses that had site supervisors and committees conducted SHEW 2.30 and 2.18 times more, respectively, than others. CONCLUSIONS: Site supervisors and SH committees were significant HR factors that improved SHEW in small manufacturing businesses.

Development of Evaluation Indicators for Hospice and Palliative Care Professionals Training Programs in Korea.

INTRODUCTION: The importance of training for Hospice and Palliative Care (HPC) professionals has been increasing with the systemization of HPC in Korea. Hence, the need and importance of training quality for HPC professionals are growing. This study evaluated the construct validity and reliability of the Evaluation Indicators for standard Hospice and Palliative Care Training (EIHPCT) program. METHODS: As a framework to develop evaluation indicators, an invented theoretical model combining Stufflebeam's CIPP (Context-Input-Process-Product) evaluation model with PRECEDE-PROCEED model was used. To verify the construct validity of the EIHPCT program, a structured survey was performed with 169 professionals who were the HPC training program administrators, trainers, and trainees. To examine the validity of the areas of the EIHPCT program, exploratory factor analysis and confirmatory factor analysis were conducted. RESULTS: First, in the exploratory factor analysis, the indicators with factor loadings above 0.4 were chosen as desirable items, and some cross-loaded items that loaded at 0.4 or higher on two or more factors were adjusted as the higher factor. Second, the model fit of the modified EIHPCT program was quite good in the confirmatory factor analysis (Goodness-of-Fit Index > 0.70, Comparative Fit Index > 0.80, Normed Fit Index > 0.80, Root Mean square of Residuals < 0.05). The modified model of the EIHPCT comprised 4 areas, 13 subdomains, and 61 indicators. DISCUSSION: The evaluation indicators of the modified model will be valuable references for improving the HPC professional training program.

Health Beliefs Associated with Cancer Screening Intentions in Korean Workers.

BACKGROUND: Cancer is a leading cause of death in Korea. To prevent cancer, it is essential to facilitate and promote appropriate cancer screening behavior in the adult population. The aim of this study was to examine health beliefs related to cancer screening intentions using the Health Belief Model (HBM). MATERIALS AND METHODS: The research participants comprised 275 male health and safety managers at commercial companies in Korea. The selfadministered survey explored demographic characteristics, cancerrelated factors, beliefs about cancer/cancer screening (BCCS) (vulnerability to cancer, severity of cancer, benefits of screening, and barriers to screening), and cancer screening intention. Multivariate logistic regression analyses were used to identify factors associated with an intention to be screened for cancer. RESULTS: Perceived health status and need for cancer prevention education were major factors associated with BCCS. Poorer health status was associated with greater perceived vulnerability, a perception of fewer benefits, and more barriers (p<0.05). A perceived greater need for cancer prevention education was associated with a higher perceived severity of cancer and more perceived barriers to screening (p<0.05). Marital status, cancer screening experience, and perceived vulnerability to cancer were significant influences on the cancer screening intention (p<0.05). Participants who had undergone cancer screening in the past 2 years were more likely to intend to be screened for cancer than were those who had not been screened; this was true across all degrees of intention and all types of cancer (p<0.01). Hesitant people considered themselves less vulnerable to gastric, lung, and liver cancer than did the poeple who intended to undergo cancer screening (p<0.05). CONCLUSIONS: Based on our findings, we recommend that workplace cancer prevention programs attempt to increase awareness about vulnerability to cancer among workers who hesitate to undergo cancer screening.

A polymorphism at -1607 2G in the matrix metalloproteinase-1 (MMP-1) increased risk of sudden deafness in Korean population but not at -519A/G in MMP-1.

OBJECTIVES/HYPOTHESIS: Matrix metalloproteinase-1 (MMP-1) is associated with a risk of inflammatory disease and cancer invasion. Two common etiologies for sudden deafness (SD) are circulatory disturbance and inflammation. The present study aimed to investigate whether MMP-1 polymorphisms are associated with SD. STUDY DESIGN: Case-control study. Ninety-nine Korean SD patients and 530 normal patients (controls) were used in this study. METHODS: Single nucleotide polymorphism (SNP) of MMP-1 (at -1607G/2G and -519A/G) was analyzed using the pyrosequencing method. RESULTS: At MMP-1 -1607G/2G, the distributions of 2G/2G, G/2G, and G/G genotypes in controls were 36.8%, 44.3%, and 18.9%, respectively, and in SD patients were 46.5%, 48.5%, and 5.1%, respectively. The 2G/2G genotype was found to increase the risk of SD compared with the G/G genotype (codominant model: P = .0029; recessive model: P = .0003). The 2G allele was found to increase the risk of SD compared with the G allele (P = .002). At MMP1 -519A/G, there was no statistically significant increase in the risk of SD. Among haplotypes of MMP-1 polymorphisms -1607G/2G and -519A/G, 2GA and GA were found to be associated with SD (P < .05). CONCLUSIONS: These results suggest that the 2G/2G genotype is associated with an increased risk of SD compared with the G/2G and G/G genotypes. Furthermore, the 2G allele may be a risk factor for SD.

Social support for stress prevention in hospital settings.

AIMS: The purpose of this study was to identify the effects of social support, interacting with work stressors, on psychological stress prevention in a public hospital, based on Karasek's demand-control-support (DCS) model. METHODS: A self-administered survey was conducted with 240 employees of a public hospital in the south-east of the United States. The survey asked for demographic information, details on job demands and job control as work stressors, social support, and depressive symptoms as the representative psychological stress symptoms. RESULTS: Social support was detected as a primary interpersonal positive factor buffering depressive symptoms. Social support was also related to job control and depressive symptoms in the simple correlation. Only the main effect model with general characteristics was significantly accepted in hierarchical regression analysis (p = .04). High social support was associated with low depressive symptom scores, which means that social support had a positive association with health care employees' mental well being. However, any two-way or three-way interaction model was not accepted. The main effect part of the demand-control-support model was supported; however, interactions between demands, control, and support failed to be supported.

A longitudinal study of the relationship between health behavior risk factors and dependence in activities of daily living.

OBJECTIVES: The purpose of this study was to shed further light on the effect of modifiable health behavior risk factors on dependence in activities of daily living, defined in a multidimensional fashion. METHODS: The study participants were 10,278 middle aged Americans in a longitudinal health study, the Health and Retirement Survey (HRS). A multi-stage probability sampling design incorporating the effect of population sizes (Metropolitan and non-metropolitan), ethnicity (the non-Hispanic White, the Hispanic, and the Black), and age (age 51-61) was utilized. Basic Activities of Daily Living (ADL) were measured using five activities necessary for survival (impairment in dressing, eating, bathing, sleeping, and moving across indoor spaces). Explanatory variables were four health behavior risk factors included smoking, exercise, Body Mass Index (BMI), and alcohol consumption. RESULTS: Most participants at baseline were ADL independent (1992). 97.8% of participants were independent in all ADL's at baseline and 78.2% were married. Approximately 27.5% were current smokers at baseline, and the subjects reported moderate or heavy exercise were 74.8%. All demographic characteristics and behavioral risk factors were significantly associated with the ADL status at Wave 4 except alcohol consumption. Risk behaviors such as current smoking, sedentary life style and high BMI at Wave 1 were associated with ADL status deterioration; however, moderate alcohol consumption tended to be more related to better ADL status than abstaining at Wave 4. ADL status at Wave 1 was the strongest factor and the next was exercise and smoking affecting ADL status at Wave 4. People who were in ADL dependent at Wave 1 were 15.17 times more likely to be ADL dependent at Wave 4 than people who were in ADL independent at Wave 1. Concerning smoking cigarettes, people who kept only light exercise or sedentary life style at Wave 1 were 1.70 times more likely to be died at Wave 4 than the people who did not smoke at Wave 1. CONCLUSIONS: All demographics and health behaviors at wave 1 had consistently similar OR trends for ADL status to each other except alcohol consumption. Smoking and exercise in health behaviors, and age and gender in demographics at Wave 1 were significant factors associated with ADL group separation at Wave 4.

Effects of social support at work on depression and organizational productivity.

OBJECTIVE: To examine how social support at work affects depression and organizational productivity in a work-stress framework. METHODS: A self-administered survey for 240 workers in a public hospital in the southeastern United States. RESULTS: Social support at work was directly related to high job control, low depression, and high job performance. Social support did not buffer the negative effects of work factors on depression and organizational productivity. CONCLUSIONS: Social support at work had a direct and beneficial effect on workers' psychological well-being and organizational productivity without any interaction effect on the work-stress framework.

Effectiveness of a healthy work organization intervention: ethnic group differences.

This study examined ethnic group differences in the effectiveness of a healthy work organization intervention on organizational climate and worker health and well-being. Our sample consisted of employees from 21 stores of a large national retail chain. The intervention involved establishing and facilitating employee problem-solving teams in 11 of the stores. Teams were charged with developing and implementing action plans tailored to the needs of their specific site. Pre- and postcomparisons of the treatment and control groups showed that the intervention produced positive effects on both the climate and health and well-being outcomes; however, these effects varied significantly by ethnic group. Particularly in terms of organizational climate, black and Hispanic employees were the primary beneficiaries of the participatory intervention process. These results are interpreted in terms of social identification and self-categorization theories and are contrasted with traditional participatory and diversity training approaches.
