Bromilow's time-cost (BTC) relationship was examined for building projects in Vietnam using actual construction time and total construction cost. Data set was collected from 77 historical building construction projects completed between 1999 and 2005 which were adjusted by consumer price index (CPI) to 2000 price. Time-cost equations were specified respected to two sectors, public and private, in Vietnamese construction industry and all cases. It is shown that a public funded building project has the longer construction duration than a similar budget private funded project. The resulting models are statistically significant. The adjusted R-square coefficients of all cases, public and private projects models are respectively 0.403, 0.436 and 0.377 mean that the BTC regression lines moderately fit the data set.

For the quality improvement on private security industry, the quality of personnel in private security should be advanced through the systematic training. If the personnel in private security provide an advanced service in applying knowledge and technique to the field when in training, they can obtain the reliability from people. With the point of this side, practical and systematic training is essential to the restoration on the private security industry. The personnel of private security face many people in the field. So they must work with an active concept that can prevent additional crime from behavior suspicions through scientific observation method and systematic inquiry method rather than negative work with providing a friendly service in the field. For conducting this concept, therefore, this study suggested the improvement training program of "Question and Research Guides" from new employee training on existing private security. The scientific observation standard is specifically suggested from the study 'people watching' of Professor Morris, D. and an act contact question from lead technique that US FBI, police, and inspection institute are taking through the feature of human act and 'METT' that is the program for emotion capture training through human minute look is going to be applied on "Question and Research Guides" training. This will provide the educational mood for students with the training content that is available for the practical training program and the real work, and will help to restore the private security industry with obtaining people's reliability through the scientific work and advanced field treatment.

There is no prior research on organizational commitment and supervision for social welfare public officials in charge of public-private cooperation in public welfare fields. Therefore we are designed to determine the impact of social welfare public officials' public-private cooperation awareness on organizational commitment to verify the moderating effect of supervision on the effect between public-private cooperation awareness and organizational commitment. The analysis data is 242 questionnaires collected from Incheon public health and welfare officials visiting towns, villages, and villages in 10 counties. Using the SPSS 22.0 program, descriptive statistics and relationships between variables were analyzed, regression analysis was performed to analyze the influence between variables, and hierarchical regression analysis was performed to verify supervision control. As a result of the study, it was confirmed that the perception of public-private cooperation affects organizational commitment, interacts with supervision satisfaction, and has a moderating effect. Based on this, in order to improve the organizational commitment of social welfare public officials during public-private cooperation work, specific measures were proposed for sharing awareness and understanding between the public and private sectors, establishing an official system, and establishing a supervision system.

Backgrouds : This study was performed to compare the satisfaction levels for health examination programs provided by between the Korea National Health Insurance Corporation (KNHIC) and private healthcare organizations in Korea. We investigated factors associated with the satisfaction level for the KNHIC health examination. Also, factors explaining for the additional receipt of private healthcare organization's examination were identified. Methods : A self-administered questionnaire survey was conducted in June 2004 with 250 beneficiaries of the KNHIC industrial workers' program and 100 beneficiaries of the KNHIC selfemployed program. A total of 297 completed the questionnaire, including 213 (85.2%) and 84 (84.0%) for each insurance program. Ten questions measuring satisfaction levels for each examination program were rated on a scale ranging from 1 (strongly unsatisfied) to 5 (strongly satisfied). Results : Among the subjects receiving both examinations, the mean satisfaction level for the KNHIC examination (3.07) was significantly lower than that for the private healthcare organization's examination (3.50) (p<0.05). The KNHIC examination showed lower satisfaction for all of the 10 items than the counterpart. In particular, the KNHIC examination had the scores of lower than 3.0 for the items reflecting post-examination management services. According to the multiple regression analysis results, the satisfaction for the KNHIC examination was positively associated with the positive attitude toward health examination(${\bullet}$,=0.38, p<0.00). The logistic regression results showed that the likelihood of receiving the private healthcare organization's examination in addition to the KNHIC examination increases as the respondents were less healthier(OR=0.29, 95% CI = 0.10¢¶0.84), the satisfaction level for the KNHIC examination decreased(OR=0.46, 0.28¢¶0.75) or the attitude toward health examination was more positive (OR=2.56, 1.31¢¶5.12). Conclusion : The relatively low satisfaction level for both examination programs suggests that there's ample room for improvement of health examination services in Korea. The negative association between additional receipt of private healthcare organization's examination and satisfaction level for the KNHIC examination implies that the improvement of the satisfaction for the KNHIC examination would help to reduce the national expenditure spent on the additional examination.

The present study assessed children's perceptions of risk of sexual abuse before and after participation in a sexual abuse prevention program, and investigated the effects of the sexual abuse prevention program on the children's emotional response. The subjects for this study were 135 3rd and 145 6th graders, attending elementary school in Seoul. Instruments were the Sexual Abuse Situational Risk (Jacobs, Hashima, & Kenning, 1995) and the Children's Emotional Response Questionnaire (Garbarino, 1987). The results of this study were that (1) children's perceptions of the risk of sexual abuse by a stranger decreased, relative to those by familiar persons which increased after the program. Especially, 6th graders had higher perceptions of the likelihood of abuse by familiar persons than 3rd graders. Girls had higher perceptions of risk than boys. (2) Children perceived adults as more dangerous than adolescents both before-and after-program. (3) Children's perceptions of the risk of sexual abuse in public settings decreased, relative to perceptions of risk in private settings which increased after the program. Girls had higher perceptions of the liklihood of abuse in private settings than boys; no significant difference was found by grade. (4) Children's emotional response did not reveal a significant change between pretest and posttests.

Purpose: This study analyzed the effects of a health policy capacity development education program as a publicprivate partnership (PPP) model in official development assistance (ODA) for health policy administrators. Methods: Between October 2015 and September 2017, 41 participants from underdeveloped countries completed the three-week education program at K university, following the official selection process of the Korea International Cooperation Agency (KOICA) and each country's embassy. Results: The effects of the health policy capacity development education program differed significantly according to participants' age (p=.043), country region (p=.045), and academic or professional degree (p=.007). Academic or professional degree significantly predicted the effects of the program (β=.41, p=.007), explaining 21.7% of the variance in the regression model. Conclusion: The current selection process for ODA program participants considers recommendations from each country's embassy to determine eligible candidates. The hosting institution's opinions or suggestions regarding participants' professional expertise or work experience, country region, or demographic characteristics should also be considered in the participant selection process.

Purpose: This study aimed to identify factors influencing depressive symptoms in public and private sector employees. Methods: Survey data on 23,602 workers who had worked in the public or private sector were obtained from the 2014 Korean Working Condition Survey (KWCS). Symptoms of depression were measured using the WHO-5 Well-being Index. Data were analyzed using a $x^2$ test, t-test, and multivariate stepwise logistic regression to determine the factors affecting the symptoms of depression. Results: First, the prevalence of depressive symptoms was 41.1 % in public sector employees and 43.4 % in private sector employees. Second, the factors commonly affecting depressive symptoms in public and private sector employees were residence area, cognitive demands, development opportunities, social support from colleagues, social support from supervisors, social community at work, job rewards, and work-family conflict. In addition, age, company size, atypical work, ergonomic risks, quantitative demands, emotional demands, influence, and job insecurity were found to be predictors of depressive symptoms unique to private sector employees. Conclusion: Mental health programs including the employee assistance program (EAP) should be developed and implemented after considering the risk factors affecting depressive symptoms.
