Purpose: The purpose of this study is to find a way to improve and overcome the psychological treatment limited to the negative factors dealt with in psychology from a positive psychological point of view. To this end, this study aims to verify whether a positive psychotherapy program can improve happiness, resilience, and post-traumatic growth along with improvement of psychological symptoms such as depression. Research design, data and methodology: To this end, in this study, mean difference analysis was conducted using t-test on 10 participants in the 16th PPT program and 14 in the control group. Also, after setting the main variables, we tried to confirm the effectiveness through simple regression analysis and multiple regression analysis of the causal relationship model. Results: As a result of the independent sample t-test and the paired sample t-test, it was confirmed that the group participating in the PPT program had higher flourish, happiness, resilience, post-traumatic growth, and lower depression. In addition, as a result of regression analysis, it was confirmed that post-traumatic growth had a positive effect, and that depression was a life-threatening factor. Conclusions: Since the PPT program has a positive effect on the participants with relatively negative psychological symptoms, it is necessary to expand it. In addition, it is necessary to introduce various preventive programs such as PPT as well as traditional psychological treatment for negative symptoms such as depression.

Purpose - This research paper aims to examine the impact of entrepreneurial orientation (EO) and government support programs (GSP) on new product performance in Korean Small and Medium-sized Enterprises (SME). We specifically focus on the interaction between these two factors and their influence on the new product performance of Korean SMEs. Research design, data, and methodology - We collected survey questionnaires from SMEs that are certified with Inno-biz by the Korean Ministry of SMEs and Startups. The collected data was analyzed using SPSS 26 and AMOS to create an integrated model. Result - Based on the analysis, our findings indicate that the proactiveness and innovativeness dimensions of EO have a positive effect on new product performance. However, the risk-taking dimension of EO has a negative effect. Additionally, GSP exhibit both positive and negative moderating effects on different dimensions of EO. Conclusion - It is important to recognize that GSP are not a universal solution for all challenges faced by SMEs. Hence, it is crucial for policy-makers to have a clear understanding of SMEs' capabilities and the level of EO dimensions in order to identify types of GSP that could lead to positive outcomes, while minimizing the negative effects of GSP.

The main objective of this study is to examine the impact of entrepreneurial orientation (EO) on small and medium-sized enterprises' (SMEs) performance in the context of subcontracting buyer-supplier relation. Specifically, we seek to examine whether the power dynamics between buyer and supplier either support or hamper subcontracting SMEs' ability to effectively pursue EO for enhancing their performance. Research design, data, and methodology: We collected survey questionnaires from Korean SMEs that are certified with Inno-biz by the Korean Ministry of SMEs and Startups. The collected data was analyzed using SPSS 26 and AMOS to create an integrated model. Result: Based on the analysis, our findings indicate that the proactiveness and innovativeness dimensions of EO have a positive effect on the SMEs' performance. However, the risk-taking dimension of EO has a negative effect on performance. Additionally, buyer dependency exhibit both positive and negative moderating effects on different dimensions of EO. Conclusion: For SMEs that rely heavily on a particular buyer in terms of sale, pursuing innovativeness dimension of EO could lead to positive performance, while pursuing proactiveness dimension of EO had a negative moderating effect on performance.

Purpose: While there has been extensive research on discretionary accruals (hereafter, 'DA') and accounting conservatism, interpretations have varied among researchers depending on how discretionary accruals are determined as proxies. This study investigates the relationship between discretionary accruals (DA) and accounting conservatism, focusing on the distinctions between signed DA and absolute DA. Research design, data and methodology: Using financial data from companies listed on the KOSPI and KOSDAQ markets from 2010 to 2020, we employ regression analysis to explore how signed and absolute DA impact accounting conservatism. This approach allows us to parse out the effects of positive versus negative discretionary accruals systematically. Results: Our findings indicate a divergent impact of DA on accounting conservatism. Specifically, in cases of negative DA, an increase in DA corresponds with heightened accounting conservatism. Conversely, when DA is positive, increases in DA do not exhibit a significant relationship with changes in accounting conservatism. These effects suggest that the nature of DA-whether it represents upward or downward earnings adjustments-critically influences its relationship with conservatism. Conclusions: The results elucidate the nuanced role of discretionary accruals in influencing accounting conservatism. The decrease in accounting conservatism associated with absolute increases in DA appears primarily driven by groups with downward earnings adjustments. This suggests that as negative DA diminishes toward zero, accounting conservatism intensifies, whereas positive DA does not have a parallel effect.

Purpose: The purpose of this study was to examine the impact of body mass index (BMI) and waist circumference (WC) for pulmonary function in normal-weight and obese women. Methods: Data from women aged ${\geq}40$ years were obtained from the 2011 Korean National Health and Nutrition Examination Survey. Obesity was measured by BMI and WC and pulmonary function was measured by forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), and a ratio between forced expiratory volume in 1 second ($FEV_1$/FVC). Multiple linear regression analysis was performed for assessment of the association between FVC, $FEV_1$, $FEV_1$/FVC and obesity variables. Results: BMI showed positive association with FVC, $FEV_1$, $FEV_1$/FVC, and WC showed positive association with $FEV_1$ and $FEV_1$/FVC in normal-weight women. BMI and WC showed negative association with FVC, $FEV_1$ in obese women. A 1 unit increase in BMI showed an association with a 25-mL reduction in FVC and a 19-mL reduction in $FEV_1$. A 1-cm increase in WC showed an association with a 6-mL reduction in FVC and a 4-mL reduction in $FEV_1$. Conclusions: BMI and WC showed negative association with pulmonary function in obese adult women. Therefore, obese women with reduced pulmonary function should be encouraged to lose weight for improvement of their pulmonary function.
