Background: Outdoor workers are at risk of high ultraviolet radiation exposure, and may have difficulty using sun protection. The objectives were to determine the prevalence of sun protection behaviors in a sample of outdoor construction workers, and to assess which factors predict better sun protection practices. Methods: Participants were recruited via construction unions. Workers answered a questionnaire on demographics, skin cancer risk, sun protection behaviors, and job. Sun protection behavior scores (from questions on sunscreen use, sleeved shirt, hat, shade seeking, sunglasses) were calculated by converting Likert-scale answers to scores from 0 to 4, and taking the mean (separately for work and leisure). Determinants of sun protection behavior scores were examined for work and leisure using generalized linear models. Results: Seventy-seven workers had complete questionnaire data (participation 98%). Sun protection behaviors used most often were hats (79% often/always) and sleeved shirts (82% often/always); least prevalent were shade-seeking (8% often/always) and sunscreen (29% often/always). For both work and leisure scores, the strongest predictor was skin type, with fairer-skinned individuals having higher sun protection behavior scores. Workers had higher scores at work than on weekends. Workplaces that required hats and sleeved shirts for safety purposes had higher protection behavior scores. Conclusion: This high-participation rate cohort helps characterize sun protection behaviors among outdoor workers. Workers practiced better sun protection at work than on weekends, suggesting that workplace policies supportive of sun protection could be useful for skin cancer prevention in the construction industry.

Online collaborative teaming, which has emerged as a new type of education in knowledge-based society, is being discussed actively in the areas of action learning at companies and project-based learning and inquiry-based learning at schools. It regards as an effective method for improving learners practical and highly advanced problem solving abilities, and for stimulating their absorption into learning through pursuing common goals of learning together. Different from individual learning, however, collaborative learning involves complicated processes such as organizing teams, setting common goals, performing tasks and evaluating the outcome of team activities .Thus, it is difficult for a teacher to promote and evaluate the whole process of collaborative learning, and it is necessary to develop systems to support collaborative learning. Therefore, in order to monitor and promote interaction among learners in the process of collaborative learning, the present study developed an extensible collaborative teaming supporting agent (ECOLA) in online learning environments.

Noise pollution, both in the environment and in the workplace, has been recognized as a major health hazard -one that can impair not only a person's hearing but also his physical and mental well-being. As industrialization progresses, the prevalence rate of occupational diseases is increasing, especially hearing loss, which has the highest prevalence rate among the occupational diseases. The major cause of noise is the construction of various large industries without any regulation of noise sources. Therefor, we must establish an enactment to control mechanical noise sources. as soon as possible. For the purpose of controlling the noise source, we must have exact data about such things as the sound level, the frequency of the peak sound and the revolutions per minute (r.p.m.) of the machine (a measure of the power of its motor). This study was undertaken in order to define the noise characteristics, the power of the machine's motor, the change of the sound level and the peak sound as the r.p.m. increases, and the permissible exposure time. The sample size of this study was 74 machines at 11 plants in 6 industries. The results are as follows; 1. The breakdown of the types of mechanical noise noted was : 63.6% continuous normal sound, 26.9% intermittent sound, 4.7% continuous repeating sound and 4.6% impulsive sound. 2. With respect to the type of industry, the overall sound level was the highest in the mechanical industry, with $103.8{\pm}2.8dB(A)$, and lowest in the textile industry, with $89.2{\pm}1.43dB(A)$. 3. With respect to the type of machine, the highest sound level was 124 dB(A) caused by Gauzing(II), in the mechanical industry, and the lowest was 76 dB(A) caused by Attachment (Jup Chack) (I) in the timber industry. 4. The shortest permissible exposure time to Gauzing(II) in the mechanical industry was less than 15 minutes. 5. Among 74 machines, 68.2% of the peak sound was situated in the high frequency range (52.7% at 2 KHz, 4.1% at 4 KHz and 1.4% at 8 KHz). 41.8% of the peak sound was in the middle frequency range (4.1% at 250Hz, 14.8% at 500Hz and 22.9% at 1KHz). 6. If one machine had two motors or more, the peak sound was shifted to the low frequency range. 7. As the r.p.m. increased, the overall and peak sound levels were increased without any change of the frequency of the peak sound. 8. Whenever the machines had the same kind and the same r.p.m., the overall and peak sounds were changed by the physicochemical characteristics of the raw materials and the management.

Objectives: This study was conducted to assess the trend of work-related accident rate in the past 10 years (2002~2011) in Gusan district, Ministry of Employment and Labor, Korea. Methods: To analyze the change of work-related accident rate in the past 10 years in Gunsan District, we analyzed the work-related accident and disease by the type of business, business scale and analyzing the victim's age and job period using workplace information management system(PKMS) in the Ministry of Employment and Labor. Results: The average rate of work-related accidents in Gunsan district was 0.96% in the past 10 years and it was a little higher than that of national average 0.75%. The rates of work-related accidents tended to decrease from 1.11% in 2002, to 1.09% in 2006, and to 0.79% in 2011. Mortality (per 10,000) rates also tended to decrease in the years 2002, 2006, and 2011 as 3.07, 2.46, and 1.53. By the type of business, the average rate of work-related accidents in the past 10 years was the highest in agriculture as 1.77%, followed by forestry farming at 1.76%. By the business scale, the average rate of work-related accidents was the highest in the group of under 5 employees as 2.05% and it was the lowest in the group of more than 300 employees as 0.50%. The ratio of work-related accidents in the 30's age group was decreased from 41.7% in 2002 to 25.2% in 2011 and the ratio for the 50's age group was increased from 28.6% in 2002 to 49.5% in 2011. Conclusions: Although the rate of work-related accident was decreased in the past 10 years, the polarization of work-related accidents rated by the business scale and age groups show a significant difference. So it is needed that the planning and implementing of work-related accidents prevention policies.

Objective: This study was carried out to assess the status of working environments, to improve the working environments, and to be helpful to prevent occupational disease. Methods: The authors measured the noise level, concentration of dust, heavy metals, organic solvents, and other chemicals at 95 industries (22 working processes) by type of working process in manufacturing industry of parts and accessories for motor vehicles and its engines from January to December 2003. Samples were measured and analyzed by regulations of Korea Ministry of Labor, manuals of National Institute for Occupational Safety and Health (NIOSH) and Occupational Safety and Health Administration (OSHA). Results: Results are as follows. 1. Major processes exceeding mean noise levels provided the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV) were shakeout [97.5 dB(A)]. shot-blast [94.2 dB(A)], pressing [92.9 dB(A)], crushing [91.2 dB(A)], and cleaning [90.6 dB(A)]. 2. Mean concentrations of dusts were not exceeded to the TLV. But concentration on some points of processes as like welding (6.50 mg/m3), foundry (5.24 mg/m3) were exceeded. 3. Mean concentrations of heavy metals were not exceeded to the TLV. 4. Mean concentrations of organic solvents and chemicals were not exceeded to the TLV. 5. Improving rate for working environment were significantly higher in industries with health manager than without (p<0.05), and by increasing the year of working environmental measurement (p<0.01). Conclusions: The results suggest that working processes of exceeding to the TLV will be needed rapid improvement of the working environment, and also the others will be needed positive management of the working environment. Health managers must be recommended to employ in the workplace, and further studies for relationship between working environment and health effects for the workers must be carried out.

This paper aims to examine whether there are significant differences in various aspects of a household's arrangements by type of employment of married woman; 1) the extent of the division of labor, 2) the authority of decision making, and 3) financial and expenditure responsibilities. It also investigates the determinants of gender equality in the family. Based on data collected in the fall of 2002 from a representative sample of the Korean population, this study finds that nonstandard employment of married woman including temporary work and daily basis work does not contribute to gender equality within the household, although most of nonstandard employees are full-time workers. However, standard employment of married woman contribute to gender equality in the family. The results of this study show that husbands whose wives are standard-employed are more likely to take part in housework chores that are female-dominated, and standardly employed wives are more likely than non-standardly employed or housewives to take part in the household's financial and expenditure responsibilities. Standardly employed wives also have more power in decision making process within households. On the contrary, non-standardly employed wives gain no advantage over housewives within their families, due to lack of bargaining resources that enable them to affect the household's arrangements. Thus, they have confronted additional burdens, which stem from carrying the dual role of doing house work as well as paid work. Such increasing work-family conflict may bring about disruption of family. Therefore, this study maintains that it is high time that government-level efforts should be made in order to improve the status of irregularly employed wives in the workplace.

The purpose of this study was to identify the effect of dental hygienists' perceptions of dental organizational culture and professional identity on organizational commitment. A survey was conducted with 310 dental hygienists working in dental hospitals and dental offices. If dental hygienists experience organizational cultures as having different degrees of organizational commitment, then the type of organizational culture and commitment may be important variables in understanding and reducing the turnover rate of dental hygienists and improving workplace performance. Efforts to form a healthy and positive organizational culture may therefore be necessary. The organizational culture most recognized by the dental hygienist was hierarchical culture (3.39) and the least recognized was task-orientated culture (2.71). The professional identity of the dental hygienist was 3.75 and the organizational commitment was 2.98. Correlation analysis was conducted to investigate the relationship between dental organization culture type, professional dental hygienist identity, and organizational commitment. As a result, professional identity and organizational commitment showed positive(+) correlation with innovation oriented culture and relationship oriented culture. Among the organizational culture types, relationship-orientated culture (p<0.001) and innovation-orientated culture (p=0.006) were significant influences on organizational commitment, and professional identity did not have a significant influence. The regression model was found to be statistically appropriate (F=11.857, p<0.001) and the model explaining power was 14.9%. These results suggest that efforts to create a relationship-orientated culture and an innovation-orientated culture and to reduce the hierarchical culture can be a strategy to enhance the organizational commitment and the professional identity of dental hygienists.

Objectives: The new Chemical Control Act from the Korean Ministry of Environment (2014-259) simply states only in basic phrases that every worker handling the listed chemicals should wear personal protective equipment (PPE) and does not consider the different hazard characteristics of particular chemicals or work types. The purpose of this study was to produce an exposure risk matrix and assign PPE to the categories of this matrix, which would be useful for revising the act to suggest PPE to suit work types or situations. Methods: An exposure risk matrix was made using hazard ranks of chemicals and workplace exposure risks in the previous study. For the 20 categories of exposure risk matrix PPE, levels A, B, C, D as classified by OSHA/EPA were assigned. After 69 hazardous chemicals were divided into 11 groups according to their physiochemical characteristics, respirators, chemical protective clothing (CPC), gloves and footwear were suggested on the basis of the assigned PPE levels. Results: PPE table sheets for the 11 groups were made on the basis of work types or situations. Full facepiece or half-mask for level C was recommended in accordance with the exposure risk matrix. Level A was, in particular, recommended for loading or unloading work. Level A PPE should be worn in an emergency involving hydrogen fluoride because of the number of recent related accidents in Korea. Conclusion: PPE assignment according to the exposure risk matrix made by chemical hazards and work type or situation was suggested for the first time. Each type of PPE was recommended for the grouped chemicals. The research will be usefully used for the revision of the Chemical Control Act in Korea.
