Background: The mining industry is known worldwide for its highly risky and hazardous working environment. Technological advancement in ore extraction techniques for proliferation of production levels has caused further concern for safety in this industry. Research so far in the area of safety has revealed that the majority of incidents in hazardous industry take place because of human error, the control of which would enhance safety levels in working sites to a considerable extent. Methods: The present work focuses upon the analysis of human factors such as unsafe acts, preconditions for unsafe acts, unsafe leadership, and organizational influences. A modified human factor analysis and classification system (HFACS) was adopted and an accident predictive fuzzy reasoning approach (FRA)-based system was developed to predict the likelihood of accidents for manganese mines in India, using analysis of factors such as age, experience of worker, shift of work, etc. Results: The outcome of the analysis indicated that skill-based errors are most critical and require immediate attention for mitigation. The FRA-based accident prediction system developed gives an outcome as an indicative risk score associated with the identified accident-prone situation, based upon which a suitable plan for mitigation can be developed. Conclusion: Unsafe acts of the worker are the most critical human factors identified to be controlled on priority basis. A significant association of factors (namely age, experience of the worker, and shift of work) with unsafe acts performed by the operator is identified based upon which the FRA-based accident prediction model is proposed.

In recent studies, construction industry workers with higher job stress and lower work ability were more likely to experience accidents at their workplace. Likewise, fatal accidents rate was higher among simple labor workers compared to technical workers. Therefore the evaluation of a worker's job stress and work ability seems to be important in preventing the occurrence of fatal accidents. To search for ways to reduce job stress and to improve work ability, the current study conducted a job stress analysis based on age, years of service, skill level, hobbies, sleep patterns, and monthly income. For this, the Korean occupational stress questionnaire short form and the Work Ability Index (WAI) developed by the Finnish Institute of Occupational Health (FIOH) were used. In this study, SPSS 12.0K statistics program was used for statistical analysis and significance was verified by the Kruskal-Wallis test and non-parametric tests. The results of this study can be summarized as follows : (1) Simple labor workers had higher job stress and less work ability than technical workers. (2) The more experienced workers had lower job stress and higher work ability. (3) In the case of workers who slept a lot, work ability was higher and job stress was less. (4) Monthly income influenced on the job stress and work ability. (5) Job stress and work ability in accordance with the age difference was not significant.

Objectives: This study was focused on the influence of chronic aircraft noise exposure on children's continuous performance, intelligence and reading skill. Methods: We enrolled 586 children in 4-6th grade of 7 primary schools near air base in Korea. Continuous performance was measured using the computerized ADS program. We analyzed 477-512 children on the visual continuous performance test, auditory continuous performance test, intelligence test, and reading and the vocabulary test. Intelligence was measured using vocabulary, digit span, block design, and digit symbol tests of K-WISC-III. Results: The commission error and variability deviation of auditory continuous performance test and reading test were significantly higher among children in schools with the helicopter noise and the fighting plane noise compared to children in the low noised schools. Conclusion: There was a possibility that chronic aircraft noise exposure was associated with impairment of the school performance. The result of our study also shows chronic aircraft noise was associated with reading ability.

Purpose : In this study, we would like to apply oral sensory play therapy program to children with cerebral palsy who have sensitive oral senses to find out the effect on oral sensory ability, oral function, performance ability and sociality. Methods : The subjects of this study were 20 children diagnosed with cerebral palsy, and 10 experimental groups and 10 control groups. Oral sensory play therapy programs, including oral sensory programs, were conducted in the experimental group, while only oral sensory programs were conducted in the control group. Oral Sensory Treatment Level was used to identify the sensory profile and the overall oral function of the oral function was used, and the performance and satisfaction of Canadian occupational performance measure (COPM) were examined to find out the performance of the work, and social skills were examined for social skills (SMS). Results : The level of oral sensory treatment, overall oral function, work performance and sociality all increased significantly in the experimental group, but the oral sense and oral function in the control group were significantly increased, but not significantly in the case of work performance and sociality. Conclusion : Through this study, we confirmed that oral sensory play therapy program is an effective arbitration method for oral sensation, oral function, work performance and social enhancement of children with cerebral palsy. Based on the results of this study, the study of arbitration protocols for children with cerebral palsy with oral sensory problems will have to be more active.

Purpose : This study aimed to investigate the effects of health science majors' communication skills on their adjustment to college life. Methods : The subjects were 336 college students majoring in health science at colleges located in Busan. The survey's questionnaire comprised 38 items, including 15 items for communication skills and 19 items for adjustment to college life. Results : In the gender-based comparison of communication skills and adjustment to college life, female students had better communication skills, with overall higher scores than male students for the understanding others and communication. In the age-based comparison of communication skills and adjustment to college life, students aged 21 to 22 showed the best communication skills, while students aged 18 to 20 exhibited the least communication skills. In terms of adjustment to college life, those aged 25 or older scored the highest, and those aged 21 to 22 scored the lowest. In the school-year-based comparison of communication skills and adjustment to college life, third- and first-year students showed the best and least communication skills, respectively. Overall, third- and fourth-year students were more adjusted at adjusting to college life than first- and second-year students. Third-year students also scored the highest in academic adjustment, whereas second-year students scored the lowest. In terms of relationships between the students' communication skills and their adjustment to college life, communication skills were positively correlated with the following subdomains: understanding of others, self-expression, and communication. Communication skills also showed a positive correlation with adjustment to the college environment, including personal-emotional adjustment. Conclusions : The present study found that communication skills did not significantly affect health science majors' adjustment to college life. However, given that communication skills are an essential factor for effective work performance and greater job satisfaction, it is recommended that colleges provide students with relevant education and experiences to help them enhance communication skills while in school.

Objective : The present study investigated the effects of group play activities based on Ayres Sensory $Integration^{(R)}$ (ASI) on sensory processing ability, social skill ability and self-esteem of low-income children with attention deficit hyperactivity disorder (ADHD). Methods : A total of 20 low-income participants with children with ADHD were recruited and divided into an experimental group (n=10) and a control group (n=10). Sensory processing ability was measured via the Short Sensory Profile (SSP). Social skill ability was measured via the Social Skills Rating System (SSRS). To measure self-esteem, the Rosenberg's self- esteem scale was used. The experimental group received the $ASI^{(R)}$ group play activities for 50 minutes, twice per week for six weeks, while the control group did not receive an intervention. Level of significance of all statistical analyses was .05. Results : Social skill ability (F=4.443, p=.05), cooperation (F=5.328, p=.035) and self-esteem (F=5.358, p=.033) differed significantly between groups after the intervention. Conclusion : Our findings indicate that the group play activities based on $ASI^{(R)}$ are effective in improving social skill ability and self-esteem. This study provided a theoretical basis for the claim that sensory integration therapy should be applied in general elementary schools.

The object of the study is to examine the change of social-economic structure and poverty-shape to escape poverty. In Korea, the working poor have been increased by flexibility and division of labor market since the economic crisis in 1997, and are faced with hard conditions due to the vulnerable welfare system. Especially the workers who engage in irregular jobs were increased by restructure of labor market. Besides they are in unstable employment terms such as low payment, low-skill and exclusion from welfare-benefit. Many small independent businessmen are also in danger of poverty for enterprises trend to move abroad by globalization. Poverty policy in our country was focused on the absolute poor class that has relation with old age, unemployment, disable, disease etc, so they were the object of welfare policy. The poverties, however, are increasing rapidly after the economic crisis, and they work so hard but are still poor, that is, participation in labor market doesn't become an element to escape poverty. Thus the emergence of new poverties whose core consists of the working poor becomes to need new poverty policy. The study is to survey change of their economic conditions, their welfare conditions, their experiences and responses of social dangers after the economic crisis, then to explore the policy to escape poverty. As the result of the study, it shows that the working poor experienced many kinds of social dangers like unemployment, decrease of income etc. In their welfare conditions as their responses to the social dangers, the benefit of social insurance, enterprise welfare like legal retirement pay and paid leave and private welfare such as private pension and insurance are low. The working poor are faced with social dangers, moreover, they don't have skill or education for adapting themselves to information society. The study says that it needs variable policies for the working poor to escape poverty, and suggests payment & tax policies as stable income policy, occupational discipline and skill-education for promoting the quality of employment, moreover, social insurance as expansion of social welfare policy and housing & education policies whose objects are the working poor.
