The TOEIC has widely used to evaluate business English proficiency in Korea, but those who achieved high scores still often face difficulties in performing their duties in English at work. This implies that the test may not evaluate business English proficiency effectively enough. With an ultimate goal of proposing an effective way of assessing business English proficiency, therefore, his study analyzed the predictive validity of the TOEIC. A correlation analysis was conducted between TOEIC scores of 64 office workers of multinational companies and their working skills in English evaluated by themselves, and their colleagues and seniors. Its results illustrated a significant correlation between their listening and reading scores and their working skills measured by all the groups, but not between their scores and their working skills in speaking and writing. In addition, the study did a delphi study to identify working skills in English to be assessed in business English tests and a contents analysis of the TOEIC. The results suggest business English tests should be able to assess working skills by work types and more direct testing of working skills in speaking and writing is needed.

An analytical and experimental study has been conducted to determine the optimal charging mass of working fluid for the maximum heat transport capacity of heat pipe with axially grooved wick. When the heat pipe is operated in a steady state, the liquid-vapor meniscus recession of working fluid to the bottom of groove is occurred in the evaporator region. In this work, the optimal charging mass of working fluid was obtained by considering the meniscus recession from the axial variation of capillary pressure, the radius of curvature and wetting angle of meniscus of liquid-vapor interface. Experimental results were also obtained by varying the charging mass of working fluid within a heat pipe, and presented for the trend of maximum heat transport capacity corresponding to the operating temperature and the elevation of heat pipe. Finally, the analytical results of the optimal charging mass of working fluid were compared with those from the experiment, both of which were in good agreement with each other.

The purpose of this study is to investigate the level of role stress perceived by employed housewives working in sales departments, and further, to devise coping strategies that can help reduce stress resulting from their multiple roles The sample of this study consisted of married women who were working in sales departments, who have at least one child, and who live in the greater Seoul metropolitan area. A total of 343 out of 450 originally distributed questionnaires were used for the analysis in this study. The findings of the study are: 1 The housewives in sales departments felt stress most severely in their role as a mother. Next were the roles as a wife, housewife, daughter, daughter-in-law, and working woman, in that order. 2. It appeared that age and the motive for employment affected the overall level of role stress among housewives. The two variables (age and the motive for employment) explained about 23% of the variance. The younger they were the higher was the level of role stress. Also, if they were working for an economic reason (to support the family), they tended to be more stressed out. The results of this study could be utilized as baseline data for policy-making, consultation, and development of educational programs for housewives working in sales departments, an area that has hardly been explored.

The purpose of this study was to investigate working mothers'parenting stress. The study was approached from an ecological perspective. Data were collected from 185 mothers who were professionals, office or labor workers, and have their children enrolled at the day care center located at their workplace. All the subjects lived in Seoul. The results of this study were as follows: 1. The working mothers'parenting stress was found to be at a moderate level(Mean=2.30). 2. The hierarchical and stepwise regression analyses revealed that significant variables in explaining the parenting stress of working mothers were the degrees of attachment with the subject's mother($\beta$=-.24), age($\beta$=-.23), the degrees of flexibility in working conditions($\beta$=-.19), educational level($\beta$=.18), the degrees of husbands'participation in child care($\beta$=-.17), and the number of children ($\beta$=.16). These variables explained 17.2% of working mother's parenting stress. 3. It was found that the effect of microsystem variables on working mothers' parenting stress were greater than the combined effects of mesosystem, exosystem and macrosystem variables.

The purpose of this study was to evaluate the effect of implementing the HACCP system on foodservice establishments. At first, the hygienic conditions were measured by microbiological hazard analyses of the cooking utensils and working areas. In order to solve the detected problems, the HACCP system was implemented, after what was considered a sufficient settlement period following the initial assessment, then microbiological verification was performed again. In relation to the cooking utensils and equipment(kitchen knives, cutting boards, knives for shredding vegetables, refrigerators, baskets, barts, working tables, preparation tables, tungs, dish-clothes and drains) the microbiological inspection on the Total Plate Count, Coliforms, Staphylococcus aureus and Listeria monocytogenes, were conducted with regard to the working areas(working tables, preparation tables, seasoning's shelves, serving tables, drinking water tables, refrigerators, storage rooms and dining tables), the Total Plate Count and Fungi were also examined. According to the microbiological hazard analyses there were many problems, especially with cutting boards, baskets, barts, dish-clothes and sinkballs. However, by introducing the HACCP system, the microbiological hazard levels were able to be controlled and lowered, and the total aerial bacteria in the working areas of the foodservice establishments were detected at levels below 6 CFU/plate.

This study was conducted in order to investigate the role of working memory in word recognition. As a preliminary step in tackling this topic, word frequency and working memory load were manipulated in a naming task. The results showed that word frequency is significantly involved with the working memory load. The effects of working memory load were greater in low-frequency word processing than in high-frequency word processing. These results indicat that working memory is involved more in the processing of low-frequency words. The implications for the teaching of children at the early reading acquisition stage are discussed in this paper.

This study investigated the change in stiffness and deflection of a scaffold working plate caused by damage to a cross-beam in the plate. Experiments were conducted considering various load and damage conditions of cross-beams. A cross-beam falling off from the working plate was considered damaged. The load-displacement curves of specimens at the center of the uniform load showed that the working plate stiffness decreased by 14.66%-1.89%, depending on the load interval due to the damage of one cross-beam. A reduction in the stiffness of 33.94%-40.76% resulted from the damage of two cross-beams. Moreover, the displacement increased by an average of 25% when one cross-beam was damaged and an average of 65% when two cross-beams were damaged. Therefore, damage to the cross-beam in the working plate can potentially cause accidents and harm workers. As the load increases, the risk of an accident due to the aforementioned damage also increases because the stiffness remarkably decreases with the load increase. Further, the damage to the cross-beam mainly reduces the stiffness but increases the displacement rather than the strength of the working scaffold plate.

The 52-hour workweek policy in Korea is a system that limits the maximum working hours per week to 52 hours including holiday work, which has been treated separately from overtime work during a week. Although this policy is designed to improve the quality of life and create jobs, it may also reduce the income of some workers. In general, it can be assumed that reduced working hours increase consumption at home. This study analyzed the effect of the 52-hour work policy on meat consumption patterns with the ordered logit model. Major factors considered in this study include working hours, income, and consumption frequency. It distinguished domestic and workplace consumption. The results show that the policy has had an impact on meat consumption patterns both at home and at work. If there is no change in income and only the working hours decrease, meat consumption in households increases. On the other hand, if both income and working hours decrease, household meat consumption decreases. Moreover, reduced working hours decrease the frequency of office happy hour and meat consumption in the workplace. However, the 52-hour workweek policy applies only to workers working more than 52 hours per week; thus, it is difficult to determine the overall effect of the policy on national meat consumption patterns.

Objective: The goal of this study was to investigate the effects of early childhood teachers' current working conditions such as welfare and wages, working hours, ECEC center's environmental characteristics, and parental involvement and community engagement on the professionalism of teachers. Method: A total of 988 respondents participated in the nationwide online survey. The data were analyzed by correlation analysis and structual equation modeling. Results: First, there were no statistically significant direct effects of ECEC teachers' working conditions on teacher professionalism. Second, there were significant direct effects of teacher efficacy and well-being on teacher professionalism. Third, there were significant indirect effects of teachers' working conditions on their professionalism, via efficacy and well-being, linking the impact of working conditions and the professionalism of teachers. Conclusion/Implication: The results of this structural model imply that policy input for teacher welfare, wage increases, and the enhancement of teachers' well-being and efficacy are valid and significant for the professional development of ECEC teachers. These results provide the data-driven evidence for the importance of welfare and socio-cognitive approaches for teachers.

The purpose of this study was to investigate empirically whether the expected effects of smart work in organizations were different between job types and positions. The development of information technology is demanding innovation of working style within the enterprise. There is a tendency to prefer the face-to-face working style in traditional organizations in the case of some positions or job types. However, many companies are carrying out smart work such as teleworking or telecommuting, flexible working time. But many companies still stick to their existing working methods. There is also the causal relationship between accepting attitudes toward smart work and expectation effects, depending on the position and the job types, even within the same organization. As a result of research, causal relationship analysis showed that the significant factors affecting productivity were teleworking and increasing work efficiency. The national social cost savings were influenced by the improvement of quality of life and flexible working hours. In order to activate communication within the organization, there was a positive effect on the increase of work efficiency. Only flexible working hours between the general manager and subordinates showed a significant difference.
