Drawing upon the resource-based-view of a firm, we investigate the moderating role of operations efficiency on the link between environmental and financial performance. Extant literature has highlighted that operations efficiency is closely associated with the environmental/financial performance of firms, but no empirical study has investigated how operations efficiency affects the link between environmental and financial performance. We argue that operations efficiency could act as a moderator of this relationship. To test the hypothesized relationships, we have used available secondary quantitative UK data, namely data on the environmental/financial performance of Britain's most admired companies. By employing moderated regression analysis, we have found strong evidence for the moderating impact of operations efficiency. Our results are useful to managers in that they show that improvements in operations efficiency in a company can also help improve environmental/financial performance and vice versa.

Purpose - The purpose of the study is to examine the relationships among the following retail operations variables: retail store operations (i.e., store management, sales personnel, promotion of merchandise), success of assortment planning, firm performance (i.e., market share, overall competitive position, profitability, product quality, consumer satisfaction), and retail buyer's demographics and firm's characteristics. Research design, data, and methodology - After conducting a pilot test, the survey was conducted in Seoul, South Korea. With using the listwise deletion method, 378 usable data sets were analyzed. For data analysis, descriptive statistics, factor analysis, and Structural Equation Modeling (SEM) methods were employed. Results - As evidenced from the path diagram, the relationship between retail store operations and the success of assortment planning is strong and significant. Retail store operations affect firm performance, though at a weaker significance than it affects the success of assortment planning. The relationship between the success of assortment planning and firm performance, is the strongest relationship observed by this research. Conclusions - The findings of this empirical study contribute to the retail/fashion buying/management field by confirming (a) the importance of assortment planning for retail firm performance and (b) the role of store operations for successful assortment planning and firm performance for fashion retailers.

Construction operations generate a significant amount of air pollutant emissions, including carbon emissions. The environmental performance of construction operations is closely relevant to the operational efficiency of each resource employed, which indicates how efficiently each resource (e.g., construction equipment) is utilized. In this context, monitoring the operational efficiency of construction equipment provides key information in managing and improving the environmental performance and productivity of construction operations. In this paper, we report our efforts to measure the operational efficiency of construction equipment, using low-cost accelerometers. An experimental study and real-world case studies are conducted to demonstrate the feasibility of the proposed approach. The results have shown the potential of this approach as an economically feasible means of monitoring the environmental performance of construction operations.

For the sustainable development, companies are making a lot of efforts such as activities of sales increase and cost reduction. Among these, efforts to use limited resources efficiently and effectively is still being made steadily. And many methods for management innovation are being introduced and used. However there were partial or temporary effects only. So there are not enough to achieve operations performance to cover the entire system. Therefore, in order to maximize performance or to improve sustainability across the companies, it is necessary to rebuild the existing system with process perspective not with existing functional perspective. This study was performed to achieve the objective that is operation performance improvement of certification body. So literature review was researched and analyed about the process innovation and the process approach. And basic model which is compatible with ISO/IEC 17021 requirement for the certification body was established in this study. Based on this model, one of the certification body was selected and operation system for this organization was established, documented and implemented through the process approach method. In the result, operations performance of certification body on the side of efficiency and effectiveness is analyzed and the effect of reconstruction of system on operations performance was figured out

The main purpose of this study is to define antecedents that influence e-SCM synchronization and to investigate how it affects e-SCM performance. We, therefore, investigate (1) the impact of firms' internal IT planning capabilities on e-SCM synchronization and on SCM process management capability, (2) the impact of firms' internal IT infrastructure on e-SCM synchronization and on SCM process management capability, (3) the impact of firms' internal SCM process management capabilities on e-SCM synchronization, and finally (4) the impact of e-SCM synchronization on SCM performance. A survey has been administrated to the firms' SCM and marketing staffs and 171 returns analyzed. The results show that (1) IT plan has not direct impacts on e-SCM synchronization, but has direct impacts on organizational support, purchasing, and operations processes except logistics process. IT plan, however, has indirect impacts on e-SCM synchronization through purchasing and operations of SCM process management capability. (2) IT infrastructure has both direct and indirect effects on e-SCM synchronization, and also has direct impacts on organizational support, purchasing, and operations processes except logistics process. (3) SCM process management capabilities have direct impacts on e-SCM synchronization. Among these SCM core processes purchasing positively influences operations, which in turn positively influences logistics process management capability. (4) e-SCM synchronization has positive impacts on SCM performance indicator (SCOR), such as delivery reliability, responsiveness & flexibility, and cost. These results indicate that e-SCM synchronization can be critical to achieve better internal performance like cost and external performance like delivery reliability, responsiveness & flexibility of firms' SCM. In sum, this study demonstrates that the intervening role of e-SCM synchronization between e-SCM performance and IT management capability and between e-SCM performance and SCM core process management capability has been significant in achieving better e-SCM performance. Therefore, it can be suggested that e-SCM performance should be accomplished in consequence of the acceleration of e-SCM synchronization through the enhancement of preceding factors for the e-SCM synchronization.

데이터베이스 시스템 관계 연산자 중에서 연산 비용이 가장 비싼 연산은 조인 연산이다. 일반적으로 CPU 기반의 조인 연산의 경우에는 하나의 코어를 사용하거나 많게는 16개 정도의 코어를 사용하여 병렬 처리를 해서 병렬화에 따른 성능 향상이 크지 않다. 이에 반해, GPGPU(General-Purpose computing on Graphics Processing Units)는 수천 개의 프로세싱 유닛을 통한 병렬 처리가 가능해서 조인 연산 수행 시간을 크게 단축할 수 있다. 본 논문에서는 GPGPU 기반에서 조인 연산 병렬화를 구현하기 위해 NVIDIA의 CUDA SDK가 사용되며, CPU 기반과 GPGPU 기반에서의 조인 연산 성능을 측정한다. 사용되는 조인 연산은 NLJ (Nested Loop Join), SMJ (Merge Join), HJ (Hash Join)이며, GPGPU 장비는 TITAN Xp, GTX 1080 Ti 및 GTX 1080을 사용한다. CPU 기반과 GPGPU 기반의 성능을 비교하고, GPGPU 기반의 조인 연산과 이전 연구의 성능과의 성능을 비교한다. 마지막으로, 실험 결과는 GPGPU 기반의 성능이 CPU 기반의 성능보다 6~328 배 빠른 성능을 보였고 향후 연구의 방향성에 대하여 토의한다.
