  • 환경과 개방화 그리고 경제성장에 대한 전통적 주장과 이를 반박하는 주장간의 논쟁은 끝나지 않고 있고, 두 가설을 검증할 수 있는 명확한 이론과 연구가 부재한 상황이다. 본 논문에서는 경제성장, 오염수준, 개방화를 설명하는 변수들을 설정하여 한국에서의 개방화와 경제성장, 오염수준과의 관계를 살펴보고 환경쿠즈네츠 곡선 가설을 검증하였다. 검증결과 한국에서는 개방화가 진전될수록 GDP가 상승하였고 개방화와 경제성장이 환경에 부정적 영향을 준다는 전통적 입장과 달리 환경수준과 개방화 및 경제성장은 정(正)의 관계로 나타났다. 즉, 개방화와 경제성장이 진행될수록 환경수준이 높아졌다. 이는 한국으로 유입되는 외국 자본의 성격이 오염집약적 산업이라기 보다는 친환경기술을 보유한 첨단기술산업임을 시사한다. 결론적으로 우리나라의 경우, 개방화와 외국자본의 유치는 환경오염을 가속화시킨다는 전통적인 가설과 달리 우리 경제를 성장시키고 환경수준을 높이는 효과를 가져온 것으로 추측된다. 아울러 교역이 증가해도 환경수준이 악화되지 않으며, 환경규제가 경제성장의 요인인 개방화를 감소시키지 않는다는 결론을 도출하였다. 이 결과는 수출경쟁력 약화 혹은 경제성장 둔화를 발생시키지 않고도 환경규제를 통해서 오염수준을 개선시킬 수 있음을 시사한다.

  • Purpose: This study aimed to construct and test a predictive model that explains and predicts the quality of life in older men living alone. Methods: A self-report questionnaire was used to collect data from 334 older adult men living along aged 65 years or over living in Jeollanam-do provinces. The endogenous variables were depression, self-rated health, instrumental activity of daily life, health promotion behaviors, the number of social participation activities and quality of life. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs. Results: The final model with 14 of the 8 analysed paths showed a good fit to the empirical data: χ2 = 173.26(p < .001, df = 53), normed χ2 = 3.27, GFI = .92, NFI = .90, CFI = .93, TLI = .89, RMSEA = .08 and SRMR = .06. Activities had direct effect on quality of life of older men living alone and social support had both direct and indirect effects. Meanwhile, function and socioeconomic status showed only indirect effects. The variables included in the eight significant paths explained 83.7% of variance in the prediction model. Conclusion: Instrumental activities of daily living and social support effect directly on quality of life in the older men living alone. Findings suggest that health care providers including community nurses need to provide social support as well as empowerment programs of instrumental activities of daily living and health promotion for improving quality of life of the older men living alone.

  • Purpose: The aim of this study was to identify the factors explaining protective behaviors against radiation exposure in perioperative nurses based on the theory of planned behavior. Methods: This was a cross-sectional study. A total of 229 perioperative nurses participated between October 3 and October 20, 2021. Data were analyzed using SPSS/WIN 23.0 and AMOS 23.0 software. The three exogenous variables (attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control) and two endogenous variables (radiation protective intention and radiation protective behaviors) were surveyed. Results: The hypothetical model fit the data (χ2/df = 1.18, SRMR = .02, TLI = .98, CFI = .99, RMSEA = .03). Radiation protective intention (β = .24, p = .001) and attitude toward radiation protective behaviors (β = .32, p = .002) had direct effects on radiation protective behaviors. Subjective norm (β = .43, p = .002) and perceived behavior control (β = .24, p = .003) had direct effects on radiation protective intention, which explained 38.0% of the variance. Subjective norm (β = .10, p = .001) and perceived behavior control (β = .06, p = .002) had indirect effects via radiation protective intention on radiation protective behaviors. Attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control were the significant factors explaining 49.0% of the variance in radiation protective behaviors. Conclusion: This study shows that the theory of planned behavior can be used to effectively predict radiation protective behaviors in perioperative nurses. Radiation safety guidelines or education programs to enhance perioperative nurses' protective behaviors should focus on radiation protective intention, attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control.

  • Purpose: This study developed and tested a hypothetical model of health promotion behavior on migrant workers based on the Health Promotion Model and the Health Literacy Skills Framework. Methods: Data were collected from 298 migrant workers in 9 regions across the country from December 2020 to March 2021. The exogenous variables were e-health literacy, occupational stress, acculturation, and social support. The endogenous variables were perceived benefits of action, self-efficacy, and health promotion behavior. Data were analyzed using SPSS/WIN 25.0, AMOS 20.0, and R-4.0.3 program. Results: The model fit was appropriate. Social support had the most significant direct impact on the health promotion behavior of migrant workers. Perceived benefits of action and self-efficacy played a mediating role in the relationship among e-health literacy, social support, and health promotion behavior. Based on multi-group analysis, the migrant worker group with less than 5 years of residency had a more statistically significant effect on the relationship between perceived benefits of action and health promotion behavior than those with over 5 years. Conclusion: Providing social support as a critical administrative strategy to enhance the health promotion behavior of migrant workers is necessary. Furthermore, when developing an intervention program utilizing the internal mechanism between social support and health promotion behavior, a self-efficacy-enhancing strategy is considered to be more effective. Additionally, educating migrant workers with short-term residence of less than 5 years about the benefits of health behaviors is essential.

  • In Korean society, the theme of human errors in railway has been emerging as a critical issue. As far as human error studies are concerned, main trend has been inclined to be led by industrial engineering and systems science. Apart from those trends, this study empirically highlighted the relationship between depression, which has been a frequent research subject in the medical science and psychology, and accidents, with setting depression as an exogenous variable and cognitive failure and mistake as endogenous variables, respectively. Results of hypotheses test for the 204 respondents showed that driver's depression has a significant effect on accidents mediated by cognitive failure and mistake. This findings suggest the need for exploring the diverse latent factors causing human errors and for understanding the complex cognitive process as well as for establishing integrative countermeasures to mitigate human errors.

  • The stock market serves as a representation of economic well-being in a country. Along with the myriad of economic predictors, specific knowledge possession may lead to different macro consequences of stock performance and market value. This study empirically investigates the capacity of possessing excellent intellectual capital to increase the performance and values of listed banks in Indonesia. The selection of banks as the primary data represents such sectors' capability to attract, employ, or exploit the excellent internal capacity under the discussion of resource-based view theory. At best to the authors' knowledge, this topic's findings are still elusive and debatable upon considering the direct and indirect relationships between the proposed exogenous and endogenous variables. Eighteen listed banks form the panel data throughout 2011-2016. This study employs a path analysis and Sobel test to obtain the results of the proposed hypothesis. The results report some positive relationships of the intellectual capital to firms' performances and values, directly and indirectly, with a substantial effect on the second model compared to the first model. This study highlighted knowledge's capacity as a vital basis to gauge the banks' performance and valuation. However, a better formulation of intellectual capital is required to capture a better measurement.

  • Purpose: The purposes of this study were to develop and test a prediction model for caregiving experiences including caregiving satisfaction and burden in dementia family caregivers. Methods: The stress process model and a two factor model were used as the conceptual frameworks. Secondary data analysis was done with 320 family caregivers who were selected from the Seoul Dementia Management Survey (2014) data set. In the hypothesis model, the exogenous variable was patient symptomatology which included cognitive impairment, behavioral problems, dependency in activity of daily living and in instrumental activity of daily living. Endogenous variables were caregiver's perception of dementia patient's unmet needs, caregiving satisfaction and caregiving burden. Data were analysed using SPSS/WINdows and AMOS program. Results: Caregiving burden was explained by patient symptomatology and caregiving satisfaction indicating significant direct effects and significant indirect effect from unmet needs. The proposed model explained 37.8% of the variance. Caregiving satisfaction was explained by patient symptomatology and unmet needs. Mediating effect of unmet needs was significant in the relationship between patient symptomatology and caregiving satisfaction. Conclusion: Results indicate that interventions focusing on relieving caregiving burden and enhancing caregiver satisfaction should be provided to caregivers with high levels of dementia patients' unmet needs and low level of caregiving satisfaction.

  • The current study addresses the issue of whether the extent of cooperation between purchase and production departments relied on the food-items management, purchase process and cook's own job satisfaction. A self-administered questionnaire comprised of 61 statements was presented to the anonymous cooks to assess their perception of inter-departmental cooperation. Also, we asked them to evaluate the performance of food-items management, satisfaction with purchase process, i.e. purchase process, food-items, food suppliers, and job satisfaction. Out of 367 responses, 342 (93.2%) were available for analysis. The demographic characteristics of the respondents are presented and six hypotheses were tested using SPSS 11.0 and AMOS 5.0. The structural equation analysis revealed that the departmental cooperation between purchase and production departments, the exogenous variable, was not directly related with the respondents' job satisfaction. However, it was indirectly related with the job satisfaction through the two endogenous variables: -satisfaction with purchase process and performance of food-items management.

  • Purpose - In this article, a dynamic model like a VAR is an appropriate choice for estimating the possible interrelationship between ownership structure and firm performance as a dynamic process. Research design, data, and methodology - Data of this work are collected from Chinese stock exchange including 350 Chinese-listed firms during the period of 1999-2012. We hypothesize that this interrelationship dynamically exists between ownership structure and firm performance. To examine the correlation, a panel Vector Auto-regression (PVAR) approach generated by GMM method is utilized to test the possible dynamic relation embedded in corporate governance. Another two dynamic analysis solutions such as orthogonalized impulse-response function and variance decomposition are also used simultaneously. Results - Findings of this study indicate the evidence that dynamically endogenous relationship exists between ownership structure and firm performance. Further, there is a dynamical correlation between investment and performance. Impulse response and variance decomposition illustrate that impact of a shock to variables themselves is the main source for their variability. Conclusions - The conclusion in this study is that there is a bidirectional and inter-temporal effect between proportion of ownership and corporate performance for a long run in accordance with impulse response function. Overall, our results suggest that corporate governance in China is more market oriented.
