Today, labor unions have become more serious and have more critical roles in the IT industry. Labor union should enhance the quality of working life in an organization. It is the most important role of the union to satisfy employees. When a labor union enriches its roles, members have a positive attitude to the union. Hence, workers will be more satisfied and make more positive results. Moreover, although members have positive attitudes to the union, when labor and capital have a negative relationship, workers do not make the best performance. Furthermore, although unions and the companies work in close cooperation, when members have a negative attitude to the labor union, workers' performance will also decline. Hence, a positive attitude to labor unions and union-management relations has a mutual benefit for performance. This study explains these relationships with the effect of attitudes to labor unions (satisfaction, trust, and commitment) on organizational commitment and organizational citizenship behavior, and the moderate effect of union- management cooperation. The purpose of this study is to suggest that labor unions should have a positive relationship with management and win members' recognition in the IT field.

The purpose of this study is to analyze the changes in contents of home management part in the home economics textbooks fur middle school from the 1st to the 7th curriculum period. The contents in the all of home economics textbooks published in every curriculum period are analyzed. The major findings of this study are as follows: 1. The part of home management is divided into seven specific areas including 'definition and process of home management', 'utilization of family resource and environment management', 'time management', 'household labor/work nanagement', 'family financial management', 'purchasing', and 'consumer protection'. 2. From the 6th curriculum period, the area of 'definition and process of home management' begun to be explained using system's approach and the area of 'household labor/work management' changed its' focus from household to self management. 3. The areas emphasized in the beginning of curriculum period were 'family financial management' and 'household labor/work management'. The 'consumer protection' ' and 'utilization of family resource and environment management' were the areas emphasized in the later curriculum period. 4. The contents of 'family financial management' area have changed very little, however, the contents of 'purchasing' area have changed a lot during the all curriculum periods. 5. The contents of illustrations, tables, pictures, and activities have changed according to changes of the contents of the textbooks.

Purpose: The purpose of this study was to develop a webtoon education program on preventive self-management related to premature labor (PSM-PL) for women of childbearing age, to evaluate its effects, and to assess the usability of webtoon education for women of childbearing age. Methods: The study design was a stratified randomized trial with repeated measures. The participants were Korean women of childbearing age (between the ages of 19 and 49 years), with 49 participants each. The preventive health management self-efficacy related to premature labor (PHMSE-PL) scale, the preventive self-management knowledge related to premature labor (PSMK-PL) scale, and usability of webtoon education were assessed. The intervention group read six episodes of the PSM-PL webtoon within 2 days after clicking an online link. The control group did not receive anything but was given the webtoon after the last measurement. To test the effect of the repeatedly measured variables, a generalized estimating equation model was used. Results: The experimental group had statistically significantly greater increases in PHMSE-PL and PSMK-PL scores from baseline to immediately after and 2 weeks later than the control group. The average score for usability of webtoon education was high (4.52; standard deviation, 0.62) on a scale of 1-5. Conclusion: This webtoon education program on PSM-PL was a feasible and acceptable program that increased self-efficacy and knowledge of preventive health management of premature labor in women of childbearing age. Future studies that adopt a webtoon format can be beneficial for childbearing women with other risk factors.

Construction labor productivity, which is the greatest source of variation in overall construction productivity, is the critical factor for determining the project performance in terms of time and cost, especially during scheduled overtime when extra time and cost are invested. The objective of this research is to select an appropriate type of probability distribution function representing the variability of daily labor productivity during overtime. Based on the results of statistical data analysis of labor performance during different weekly work hours, lognormal distribution is selected in order to take advantage of easiness of generating correlated random numbers. The selected lognormal distribution can be used for development of a simulation model in construction scheduling, cost analysis, and other applications areas where representation of the correlations between variables are essential.

Traditionally, the construction industry has shown low labor productivity and productivity growth. To improve labor productivity, it must first be accurately measured. The existing method uses work-sampling techniques through observation of workers' activities at certain time intervals on site. However, a disadvantage of this method is that the results may differ depending on the observer's judgment and may be inaccurate in the case of a large number of missed scenarios. Therefore, this study proposes a model to automate labor productivity measurement by monitoring workers' actions using a deep learning-based pose estimation method. The results are expected to contribute to productivity improvement on construction sites.

The standard production unit system is the most basic element in our country construction. However, this standard production unit system shows a large difference in the actual amount of labor input for works at the Apartment housing construction, Therefore, it may be a reasonable alternative to estimate the cost of construction by historical cost data, works will be calculated the cost of labor must determine the exact amount and It is necessary to determine the exact amount of labor input for the construction progress management. This study examines the results of comparing the standard production unit system and the actual amount of labor counting in apartment housing construction was completed in the metropolitan area since 2000, the following results were obtained. the actual amount of labor input are looked for 1.184person/1000 of masonary, $0.084persons/m^2$ of plaster, $0.039persons/m^2$ of Waterproofing, $0.059persons/m^2$ of tile at the Apartment housing construction. in the actual amount of labor counting Compared with standard production unit system, masonry ratio of 59.8%, plaster ratio of 41.3%, waterproofing ratio of 31.5%, tile ratio of 34.3% and The labor rate in the works was the lowest in the plaster. was relatively high in the masonary. Therefore, the amount of labor country apartment housing construction is preferably calculated on historical cost data. But it seems that the amount of labor necessary complement ongoing close enough to the actual standard production unit system a major variable in construction management.

The moderators that relieve negative effects of emotional labor have been studied such as job characteristics and situational variables. But as reviewing these studies, they focused on the degree of emotional on certain condition, there's no distinction between that degree and moderating effects. So we should focus on the moderating variables as a organizational involvement. In this study, I hypnotized the mediating effect of job stress between emotional labor and organizational effectiveness. Then I explored moderating role of 'fairness perception of emotional labor' and 'problem-focused stress coping'. This study tested these relationships using data from 166 employees of domestic security service company. From this data, I found that emotional labor increases job stress and job stress fully mediates the relationship between individual attitude(job satisfaction, turnover intention). And one who perceives display rule fairer, feels less job stress than who is not. Lastly, one who copes more problem-focused when he/she experiences job stress, have less negative effect on turnover intention.
