This study examined the influence of mothers' and children's emotional expressiveness on children's social competence. Sixty-five kindergarten children and their mothers were observed in a lab setting which included 5 free play and 5 task episodes. The children's and mothers' behaviors during these episodes were videotaped and rated by two coders in terms of emotional expressiveness, sociability to others, ability to regulate frustration, compliance, and autonomy. Intercoder reliability between the two coders for each behavioral category ranged from .84 to .99. The results showed that children's social competence was significantly influenced by their positive expressiveness, indicating that children with higher expressiveness were more sociable to others and less frustrated in a stressful situation. Significant relationships were also found between mothers' and children's negative expressiveness, and children's compliance and autonomy. In particular, the consistency between mothers' and children's levels of negative expressiveness significantly predicted the children's compliance and autonomy. The socialization of emotion between mothers and children was discussed, as was the relationship between emotional and social competence. Suggestions for future study were also presented.

Many reaearchers have reproted that poor body postures are associated with pains or symptoms of musculoskeletal dissoders. Therefore, the ergonomic evaluation of postural stresses as well as biomechanical stresses is important when a job such as automobile assembly tasks involves highly repetitive and/or prolonged poor body postures. A macropostural classification shema was developed to characterise various body postures occurring in automobile assembly tasks in the study. To specify a postural code and stress level to each body posture, perceived joint discomforts were subjectively evaluated in the lab experiments for the full range of motion in five human body joints. Based on the reaults, a postural classification scheme was developed where the full range of motion in each body joint was classified into several codes repressenting different stress levels. The automobile tasks were clustered into 12 types based on the result walk-in-surveillance and the possible posture codes for each task type are defined. I was exposed that the poor postural problems in automobile assembly tasks were concerned in most part with arms, trunk and neck. Application of te developed schema to seven operations in automobile assembly tasks showed that the schema can be used as a tool to identify the operations and tasks involving highly stressful body postures. The schema can also be utilised as a basis to prioritise the candidate assembly operations for redesign of work methods.

This study was aiming to examine work time, frequency, work environment, and postures of retail grocery store workers to evaluate the risk of musculoskeletal disorders. An ergonomic evaluation was conducted using job analysis and posture analysis. The four most time-consuming tasks were inspecting (27.4%), arranging (21.4%), cutting (17.6%), and displaying (15.6%). The height and length of the shelves evaluated in the field was inappropriate for workers. The most common posture was a standing posture with neutral back, and bent head, right upper arm, lower arms, and hands. Finally, this paper concluded that 'arranging,' 'cutting,' and 'displaying' seemed more stressful than other operations. The result of the ergonomic evaluation would contribute to design a better workspace in ergonomics.

This study investigated the relation between stressful life events and adjustment in elementary school children, with particular emphasis on the potential main and stress-buffering effects of social support and social problem solving skills. 4-6 graders (N=170) completed the Social Support Appraisals Scale(SSAS) and social problem solving skills task. The SSAS is a 31-item measure that taps the child's perceptions or appraisals of family, peer, and teacher support. Their parents provided ratings of stress in the child's environment and ratings of the child's behavioral adjustment. Teachers provided ratings of the child's behavioral and academic adjustment. Hierarchical multiple regression analyses and graphic display were used to analyze the data. The major findings were that (1) The results for parent-rated problems supported a stress-buffering model for family support and problem solving. (2) The results for teacher-rated problems were consistent with the stress-buffering model of social support. (3) The results for grade-point average supported a main effect model for problem solving. peer support, and family support. In addition, teacher support had the strongest stress-buffering effect on grade-point average.

The objective of this study was to identify risk factors associated with the occurrence of musculo-skeletal symptoms of cashiers and provide suggestions for an improved workspace design. Workload and exertion of each task were measured using job analysis and posture analysis. The three most time-consuming tasks were waiting (43.8%), scanning (23.5%) and payment transaction (22.9%). It was analyzed that the workspace can be improved by applying Korean anthropometric data to the design of the desk height. The most common posture was a standing posture with neutral back, and bent lower arms and hands. Finally, it was revealed that 'scanning' and 'payment transaction' seemed more stressful than other operations. The result of the ergonomic evaluation would be a useful basis for designing an improved workspace.

Purpose: Child Health nurse practitioners (CHNPs) in Korea have important roles in disease management and health promotion for children and adolescents. Yet, practices of CHNPs licensed and employed in hospitals have not been adequately identified. Thus, in this study the scope of practice by CHNPs and job satisfaction and stress were investigated and compared according to the CHNPs' position in the working place. Methods: A descriptive cross-sectional survey design was used. All 53 licensed CHNPs participated in the mail survey which included a 71-item questionnaire on job performance and job satisfaction and a job contents questionnaire. Descriptive statistics, ${\chi}^2$ test, independent t-test and Mann-Whitney U test were used to compare CHNPs employed as nurse practitioner (NP) and CHNPs employed as staff nurses. Results: Compared to CHNPs employed as staff nurses, CHNPs employed as NPs more frequently provided education, environment management, coordination and research in their practice areas. No significant difference was found in job satisfaction between the two groups except for the administration and income subdomains. Only the physical exertion subdomain in job stress was stressful to CHNP employed as staff nurse. Conclusions: Job performance of CHNPs in Korea needs to be revised to include more practical practice in education, coordination, and research related areas.
