Construction industries is a labor intensive industries. According to Korea Productivity Center, most OECD members indicate high labor productivity more than Korea labor productivity in construction industries. First of all, for increasing labor productivity work efficiency and work condition should be managed by administrator in work site. Especially, work condition could be controlled by the management behaviors of administrator in work site such as work management type. This indicates that work management type could influence strongly work condition. But although that work management type could influence work condition is the characteristic of construction work is recongized to many people, the quantitative analysis on the relationship between work condition and work management type is not enough. Therefore the purpose of this study is to analyze the Influence of Work Management Type on Work Condition.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of hospital organization management. The subjects of this study were 510 employees in 1 University Hospital and 3 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from April 26 to May 7, 2004 through survey questionnaires. The main results of this study were as follows: First, From the results of multiple regression analysis to identify major influencing factors of labor union commitment level, In University hospitals, males than females, and those who had senior officer posts in labor union showed higher positive correlation with the attitude of their colleagues. In general hospitals, those who had served in Union for shorter period showed higher commitment in union. Second, When looking into the major influencing factors on the level of commitment in labor union according to their jobs, male administrators showed higher positive correlation in the level of commitment in labor union and the relationship with union. Among nurses, those who had lower education level, those who had higher job satisfaction, those who had higher emotional attachment to their job, those who had better relationship with union and better satisfaction in union showed higher commitment level. In medical technicians, those who had higher emotional attachment to their job showed higher commitment level. To summarize study results, the level of commitment in labor union depends on job satisfaction, managers' attitudes, emotional attachment to their jobs, union satisfaction factors, their colleagues attitudes toward union and thee atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as job satisfaction is important determinant in union commitment, hospital managers should have countermeasures to enhance the job satisfaction level of hospital employees. Moreover, as managerial factors of the principal of hospital influence union commitment directly, the attitudes of hospital managers toward union and transparency of hospital management should be improved.

The objectives of this study were to investigate the degrees of emotional labor, the effects to organizational effectiveness and the significant factors influencing organizational effectiveness in radiation therapy professional. The subjects of this study were the radiation therapists working at the hospital in Seoul and Gyungi. The self-reported questionnaires were administered to 205 radiation therapists and the data were analyzed with SPSS 19.0 package. The level of emotional labor of single or female subjects were revealed higher than married or male. The professionalism of job has significant correlation with emotional labor. Significant explanatory variables of the degrees of emotional labor included organization culture, distress and self-leadership. These three variables demonstrated the explanatory power of 13.9% of the emotional labor. Based on the findings, emotional labor of radiation therapist was correlated with occupational professionalism. These results suggest that the intervention program intervening emotional labor should be continued to develop in order to improve the effective self-leadership, organization culture and distress factor.

Purpose : The purpose of this study was to investigate the level of emotional labor and to identify affecting factors on emotional labor among one university hospital employees. Material and Method : This study was based on cross-sectional, self-administered, and Internet-based survey. The survey was conducted from Mar. 2 to Mar. 28. 2011. Total subjects were 812 employees working in one university hospital. Total response rate was 61.5%. Modified evaluation tool was used, which was originally developed by Morris and Feldman, to measure the level of emotional labor among hospital personnel. In order to identify the affecting factors on high level of emotional labor, we conducted logistic regression. The SPSS statistical software package was used to perform the statistical analysis. All statistical tests were 2-sided and a p-value<0.05 was considered statistically significant. Results : Average score of emotional labor was 3.06. Employees(3.39) who are working at the emergency department and hemodialysis room indicated the highest level of emotional labor, followed by wards(3.14), department of administration(3.14), department of ambulatory cares(3.06). The factors affecting on the high level of emotional labor were the highest level of schooling, types of department, and types of personality(p<0.05). Conclusion : The survey results showed that there was significant level of emotional labors among hospital employees. Therefore, the efforts to reduce the level of emotional labors are needed.

Objectives: Post-term pregnancy is a condition associated with increased maternal and fetal complications. Administration of castor oil causes cervical stimulation by increasing the production of prostaglandins. We examined the effects of castor oil on cervical ripening and labor induction through a systematic review and meta-analysis. Methods: The search process was performed to obtain relevant articles from databases including Pubmed, Cochrane library, Scopus, Science direct, SID, Iran Medex, and Google Scholar using the English keywords of cervical ripening, post-term, castor oil, labor induction, Bishop score, and pregnancy considering all possible combinations without time constraints and their Persian equivalents from national databases. Results: A total of eight related articles from the 19 primary studies were extracted and systematically reviewed. According to a cumulative chart, the difference in the post-intervention Bishop score was statistically significant (standard mean difference [SMD]: 1.64, 95% confidence interval [CI]: 1.67-2.11, p = 0.001), indicating an effect of castor oil on increasing the Bishop score. In addition, the difference in labor induction was statistically significant after the intervention (odds ratio: 11.67, 95% CI: 3.34-40.81, p = 0.001), indicating an effect of castor oil on increasing the odds ratio of labor induction (experience of vaginal delivery). Conclusion: This meta-analysis showed that oral administration of castor oil is effective for cervical ripening and labor induction. Midwives should closely monitor pregnant women with prolonged labor and collaborate with obstetricians to employ castor oil as a safe intervention to induce cervical ripening and labor to prevent undue caesarean surgery.

The purpose of this study is to clarify the reality of labor and capital productivity in the construction industry through an industry-level approach and to analyze the relationship between labor and capital productivity using a Cobb-Douglas production function. According to the research results, the construction industry has shown a very high capital productivity, while labor productivity has kept up a low level during the 1980s and 1990s. The reason was because of the lack of skillful construction workers and the decrease of capital. Meanwhile, the construction productivity has greatly increased since 2000 when there was no change in wages. This was because of a large inflow of low-wage foreign workers while the amount of value added has dramatically increased due to the liberalized sale price of apartment buildings. According to the analysis by the Cobb-Douglas production function, the elasticity coefficient of V/L to K/L in the construction industry had decreased from 1.1663 in the 1^st period(1971-1988) to 0.4465 in the 2^nd period(1989-1997), and to 0.1664 in the 3^rd period(1998-2003). Such a result means that the allocation of labor has gradually increased while the allocation of capital has decreased. Moreover there was a big increase in allocation of labor after 1998 due to the excessive deterioration of capital. In conclusion, in order to raise the construction productivity and to avoid labor-intensive production methods, investment for capital should be more increased. In particular, new machinery and equipment that can actually substitute human labor in construction sites should be more developed and applied to construction sites.

During a typical construction project, a contractor nay often find that the time originally available or normally expected to perform its work has been severely reduced. To finish the project by the completion date, the contractor is forced to find a way to speed up the progress of its work to compensate for the reduction in available time. The most frequent initial reaction of contractors to this situation is to increase on-site manpower by working longer time (overtime), adding more workers (overmanning), or implementing shift work (shift work) to increase the rate of progress. The goals of this study were to investigate how these three methods affect labor productivity and to quantify their impact on labor productivity by analyzing real project data collected from sheet metal contractors and mechanical contractors in the US.
