Environmental deterministic perspectives and resource-based perspectives have different perceptions on the factors that determine corporate performance. While the environmental deterministic viewpoint sees the external environment as having a significant impact on corporate performance. On the other hand, the resource-compliant viewpoint believes that it is important to obtain the necessary resources through appropriate decision-making in order to overcome the uncertainty of the environment. Although the external environmental impact on corporate performance is important, the study is in the position that efforts within the company to cope with environmental uncertainty are necessary. This study identified the role that factors within the company play in the process of affecting the external environment of the company's performance. This study looked at whether the CEO's innovation direction plays an mediating role in the market environment favorability affecting sales growth rate. The data was collected using a survey method. We collected data from 138 small and medium-sized manufacturing companies in Gyeongin area. The collected data was analyzed using SPSS 22 packages. According to the analysis, market environment favorability positively affects sales growth rate, and the CEO's innovation direction plays a mediating role between market environment favorability and sales growth rate. The results of this study showed that depending on the market environment, the CEO's interest and willingness to innovate, present a vision for innovation, and institutionalize innovation activities increase management performance through innovation.

Since China reformed and opened up itself, processing trade system has enormously contributed to chinese economic development and also become driving force of chinese economic growth. However, due to imbalance of industrial distribution, overproduction of labor-intensive product has expanded, and as a result, mass export of low-value-added products has aggravated trade friction. Also, these low-value-added products has caused environmental pollution and brought resource waste. On this, Chinese government start to modify system according to strategy for enhancement of processing trade. In this study, as a countermeasure of the Change of Chinese processing trade system, applicability of the bonded area is suggested. Firstly, even if a company's item is applied to prohibited or restricted items, the company can trade if through the bonded area. Secondly, even if a company has duty of deposit reservation, the company can be exempt from duty of deposit reservation if through the bonded area. Thirdly, as to importing facilities for processing trade, a company can receive more benefit through the bonded area than through outside of the bonded area.

In Japan, where ISO14001 certifications have passed the 10,000 mark, the need for environmental management has taken firm root among companies. However, in the small-and medium-enterprise sector, and among tiny businesses, there are firms not obtaining ISO certification due to their concern about human resources and increased work load. On the other hand, among businesses that have already succeeded in gaining ISO certification. one does not sense any growth with regard to the continual improvement. Voices from certain quarters indicate there is a lack of incentive to keep on improving. With this background, we herewith present a new system to evaluate the level of environmental management in a company by means of a 5-step system.

The purpose of this research is to examine the relationship between corporate social responsibility (CSR), green supply chain management (GSCM) practices, and business performances. After reviewing the extensive literature, we developed a research model including five constructs: CSR, GSCM practices, environmental, economic and operational performances. We conducted the statistical analyses based on the primary data collected from a survey questionnaire, responded by 93 different company managers in the Republic of Guatemala. Furthermore, we utilized structural equation modeling to analyze the data and to test the hypotheses. The results of the analyses showed that there is a significant influence of CSR on the adoption of GSCM practices. It was also found that GSCM practices have a significant influence on environmental, economic and operational performances. In addition, environmental performance has a significant impact on economic and operational performance. Finally, GSCM has a mediating role on the relationship between CSR and environmental and economic performance, but not with operational performance.

The average level of coke oven emissions in the work site was $0.04mg/m^3$, which was below the permissible exposure level($0.2mg/m^3$). The average level of 1-OH-pyrene in the urine of the wokers was $0.745{\mu}mol/mol$ creatinine which is far below the BEI($2.3{\mu}mol/mol$ creatinine). Correlation between airborne COE in working environment and urinary 1-OH-pyrene concentration was statistically significant. These results explain that exposure level by biological monitoring is much higher than that by environmental monitoring. The effect of hygienic measures for reducing internal exposure to polycyclic aromatic hydrocarbons was studied in 25 coke-oven workers. Their 1-OH-pyrene levels increased by $0.77{\mu}mol/mol$ creatinine, while working with ordinary protective measures. The average levels of the same workers with extra hygienic measures increased by $0.34{\mu}mol/mol$ creatinine. The average increase of the urinary 1-OH-pyrene concentration over the 5-day work week was 56.3%($0.43{\mu}mol/mol$ creatinine) lower when extra hygienic measures were taken(p=0.0001).

Stress is a primary health promotion issue in worksite research because psychological distress is closely related not only to workers　 health status but also to their job performance. This study identified the work environment and work condition factors affecting workers　 stress symptoms among the Korean manufacturing factory workers. A total of 7,818 factory workers employed in 1,562 manufacturing companies participated in the Korean nation-wide occupational health survey conducted by the Korean Occupational Safety and Health Agency in 2003. Participants were selected by the stratified proportional sampling process by standardized industry classification, company size, and locations. Trained interviewers visited the target companies and interviewed the factory workers randomly selected in each company. Work environments included physical work environments (temperature, noise, hazardous organic compounds, and so on) and psychological work environments (job demands, job control, and social support at work), and work conditions included daily working hour, rest time, and so on. Men were 71.5% and the mean age was 34.0 years old. The average working period in the present company was 6.9 years. The average stress score was 26.2 under the perfect score, 50, which means the moderate level of stress. Perceived stress had significant correlations with young age, poor physical work environment, high fatigue, bad perceived health status, and high job demands in Pearson's simple correlation analysis. Perceived health status and perceived fatigue explained 21% variance of stress symptoms and the work environment factor explained 4.8% of that; however, work condition did not have the sufficient effect. In particular, psychosocial work environment variables (job demand, job control, and social support at work) had a clear effect on stress symptoms rather than the physical work environments. Poor perceived health status, severe perceived fatigue, poor physical work environment, high job demands, low social support, heavy alcohol consumption and little exercise were significantly related to high stress symptoms in the Korean manufacturing workers.

Objectives: The purpose of this study was to compare vitamin D levels, sleep quality, and anxiety symptoms between shift workers and daytime workers and analyze the mediating effect of vitamin D and sleep quality between shift work and anxiety symptoms. Methods: The subjects of the study were 6744 people who received a medical examination while working for an electronics manufacturing company in 2016. We evaluated their shift work, vitamin D levels, sleep quality, and anxiety symptoms with blood samples and questionnaires. Chi-square test, t-test and path statistical analysis were performed. Results: The shift workers had significantly higher symptoms of anxiety than the day workers, significantly lower levels of vitamin D in the blood, and significantly poorer quality of sleep. The results of the pathway analysis confirmed that blood vitamin D and sleep quality had a mediating effect between shift work and anxiety symptoms. Conclusions: Shift workers should be constantly paying attention to mental health effects such as anxiety symptoms. Shift workers should also be alerted of the risk of vitamin D deficiency, encouraged about sun exposure and vitamin D intake, and required to undergo training and counseling on sleep hygiene.
