Due to the significant size of overseas construction projects, the cost overrun has enormous impacts on the financial status of construction companies. The managers' appropriate perception and identification of key risk factors in the construction phase notably affect the performance of projects. However, the actual impacts of risk factors and local manager' s perception of them could be deviated. For this reason, we aim to compare the performance of actual cases and general opinions of responsible practitioners in terms of risk factors relevant to cost overruns in order to present a practical strategy for risk management. Firstly, factors classified from literature review were used to simulate 290 cost overruns data sets from 20 cases by introducing Monte-Carlo Simulation and were ranked by standardized coefficients through multiple regression analysis. Secondly, a survey was conducted against 42 local managers to rank their perception of impact on cost overrun with identical factors by using Stepwise Weight Assessment Ratio Analysis (SWARA). Comparison results show that conflicts such as 'conflict with subcontractors' and 'conflict with the local community' have caused excessive cost overrun. However, managers' perception of these as less significant than the actual influences and consider other risks such as 'material price fluctuation' and 'construction quality errors', as relatively serious. Therefore, education for local managers on conflict risks needs to be presented.

This study examined the influence of adolescents' perception of empathy and peer support on happiness. The subjects of this study were 113 adolescents from U-city. Frequency analysis, reliability analysis, correlation analysis, and multiple regression analysis were performed using the SPSS 22.0 program. First, in the effect of the empathy ability perceived by adolescents on the feeling of happiness, the sub-factors of the empathy ability, such as cognitive empathy and emotional empathy, had a significant positive effect on happiness. In particular, the cognitive empathy factor of the empathy ability has more influence on happiness. Second, in the relationship between the adolescents' peer support and feelings of happiness, the sub-factors of peer support, emotional support, and instrumental support had a significant positive effect on happiness. On the other hand, the sub-factors of peer support, informational support, and evaluative support did not affect happiness significantly. In particular, the emotional support factors have more influence on happiness than the instrumental support factors. This means that a higher level of empathy and peer support perceived by adolescents results in a higher feeling of happiness. This study provides basic data for preparing educational programs to improve adolescents' happiness

College students face serious difficulties while seeking jobs, leading to a high degree of stress, which is thought to affect their attitude towards smoking. The purpose of this study was to identify the relationship between hardiness, job-seeking stress, and the attitude towards smoking among students, and to further identify the factors influencing smoking attitude. Data were collected using a structured questionnaire administered to 145 students. Data analysis was performed using the SPSS program, t-test, ANOVA, Kruskal Wallis test, Pearson's Correlation Coefficients, and hierarchical multiple regression analysis. Smokers constituted 22.1% of the sample. The study showed that smoking attitudes varied according to the smoking status (H=28.26, p<.001). The smoking attitude was seen to be desirable in the high group (t=-3.27, p=.001) and low job-seeking stress group (t=4.40, p<.001). There was a positive correlation between hardiness and smoking attitude (r=.18, p=.028). There was a negative correlation between job-seeking stress and smoking attitude (r=-.28, p=.001). Also, the factors affecting the smoking attitude were non-smoker respondent (β=.50, p<.001), job-seeking stress (β=-.23, p=.015), former smoker respondent (β=.22, p=.016) and the explanatory power was 24.3%. Therefore, school and health public center counseling and employment support programs need to help students manage and cope with stressful situations to change their attitude towards smoking in a desirable direction.

The purpose of this study is to research how a teaching personality and ethics in teaching affect the competence of students majoring in early childhood education. Questionnaires were distributed to 211 early childhood education students residing in I-city. For this study, frequency analysis, averages, and standard deviation were calculated by using SPSS 22.0, with Cronbach's alpha for the reliability test. To determine the relevance of each variable, correlation analysis and multiple regression analysis were done, with results as follows. First, the teaching personalities perceived most by the students were morality and educational principles. Ethics for infants and ethics for households were most perceived in the ethics of teaching; for competency, understanding of the curriculum, understanding infant protection, and learning support were perceived the most. Second, there is a statistically significant correlation among a teacher's personality, ethics, and competence. Third, the sub-factors of both personality and ethics have a positive effect on competence. The above results indicate that there should be multilateral research into students majoring in early childhood education to ensure they have correct and positive competency so they can provide high-quality early childhood education services, recognizing the importance of competence.

This study used data from the 6rd and 12th year of the Korean Welfare Panel to evaluate the effects of the Personal Assistance Service(PAS) system on the labor market of PAS users' participation. For the purpose of this study, 64 program groups using the Korean PAS and 344 control groups not using the Korean PAS were selected using Caliper matching among the propensity score matching. A chi-square test was used for the difference in characteristics between groups, and a simple difference-in-differences (DID) model and a double-difference multiple regression analysis of DID were performed to estimate the effect of thepolicy before and after the Korean PAS. As a result of the study, it was found that statistically, PAS had no significant effect on the labor market. This is due to the low number of system users, resulting in low post-hoc power, incomplete matching and limited availability of PAS Assistants for Disabled People. Therefore, In order to demonstrate the effectiveness of the Personal Assistance Service(PAS) system, specialized services and systems that meet the needs of the disabled and household members should be implemented.

Background: Complementary and alternative medicine (CAM) has been used frequently, and its use continues to increase in lung cancer patients, despite insufficient scientific of its efficacy. To investigate this situation, we analyzed the current awareness and use of CAM in Korean lung-cancer patients. Methods: This prospective survey-based study was performed at seven medical centers in South Korea between August and October 2019. The survey assessed general patient characteristics and the awareness and use of CAM. We analyzed differences in the clinical parameters of patients aware and not aware of CAM and of CAM non-users and users. Results: Of the 434 patients included in this study, 68.8% responded that they were aware of CAM and 30.9% said they had experienced it. In univariate analysis, the patients aware of CAM were younger with poor performance status, had advanced-stage lung cancer, received more systemic therapy, and received concurrent chemoradiation therapy (CCRT). By multiple logistic regression, younger age, poor performance status, advanced stage, and prior CCRT were identified as independent risk factors for CAM awareness. There were no significant differences in the general characteristics and cancer-associated clinical parameters of CAM non-users and users. Conclusion: Specific clinical parameters were associated with patients' awareness of CAM, although there were no significantly different characteristics between CAM users and non-users.

To establish an effective performance appraisal system, ratee accountability is essential because it increases the likelihood of meaningful utilization of performance appraisal feedback. In the context of a multi-rater performance appraisal system, this study examines the effect of the ratee general accountability and accountability to the supervisor and peers on the ratee's intention to change behavior based on the performance appraisal feedback. This study further explored the moderating effect of perceived feedback specificity on the relationship between the ratee accountability and behavioral change intention. Hierarchical multiple regression analysis was conducted using the survey data from 153 employees in eight firms with multi-rater performance appraisal systems. The results showed that ratee general accountability was positively associated with the intention to change behavior. Furthermore, perceived feedback specificity attenuated the positive relationship between the ratee general accountability and behavioral change intention, which was the opposite of the hypothesized direction. The findings indicate the importance of managing and facilitating ratee accountability for implementing a multi-rater performance appraisal system. The result also emphasizes the critical role that performance appraisal feedback plays in motivating performance improvement by providing flexible, constructive advice and behavioral change strategies instead of inducing self-defense or justification.
