Green supply chain management(GSCM) has emerged as an organizational system which helps organizations and their parter to achieve corporate profit by reducing environmental risk and cost. The main objective of this study is to investigate the relationship among organizational factors(manager support and organizational learning), GSCM practices(investment recovery and eco-design) and GSCM performance based on the BSC. Using a sample of 125 Korean companies, path analysis is used to test the research model. The results shows that the manager support has a positive effect on the investment recovery and eco-design. The results also suggest that the organizational learning directly affect the investment recovery, but do not affect the eco-design. The investment recovery and eco-design have effect on the GSCM performance. In addition, the competitive pressure has moderating effects on most of the relationships between the organizational factors and GSCM practices. This findings provides useful insights for managers seeking to adopt GSCM practices, and also provide useful guidelines for researchers to study GSCM performance.

Due to resource constraints, most of Android application developers need to address potential performance problems during application development and maintenance. The coding styles and patterns of Android programming could often affect the execution time and energy efficiency which are utilized by the Android applications. Thus, it is necessary for application developers to apply performance-enhancing programming practices for mobile application development. This paper introduces performance-enhancing best practices for Android programming, and further, it evaluates the impact of these practices on the CPU time of the application. The original version with the performance-worsening code has been refactored to become an efficient version without changing its functionality. To demonstrate the efficiency of the proposed approach, each coding pattern was evaluated by measuring the CPU time under the controlled runtime environment. Furthermore, the Android applications were evaluated and compared via the CPU time of the original version, with that of the refactored version. These experimental results indicate that, by -using the proposed programming practices, the Android developer can develop performance-efficient mobile applications.

The level of hygiene practices varies depending on a variety of factors. The purpose of this study was to evaluate the level of hygiene practices performed in the contract foodservice establishments based on several variables, and to also determine the possible effects of each variable on the performance level of hygiene practices. We surveyed 215 contract foodservice establishments, excluding school facilities, managed by a large-scale contract foodservice company. The survey used a formulated sanitary checklist to evaluate the level of hygiene practices performed in the foodservice establishments. The sanitary checklist consisted of a total of 52 items in all 6 categories including personal sanitation and process control. The collected data underwent a series of analyses such as frequency analysis, ANOVA, and correspondence analysis of means using SPSS. from the results, we found significant differences among groups in categories such as the existence of a person in charge and types of business. A higher foodstuff cost had a tendency to correlate with a higher performance level for sanitary maintenance, but there was no significance on a statistical level.
