Agriculture reservoirs need a systematic approach that can control water purity and water improvement. The area under study, Bunam Lake exceeds the agricultural water standard level due to contamination from the upper stream. When the Taean Enterprise City was planned, the water quality improvement plan was applied to minimize the environmental change. However, in order to continuously maintain the water quality in the Bunam Lake, it was essential to apply the Total Pollution Load Management System (TPLMs). In order to achieve the targeted water quality in the Bunam Lake, standard flow rates and targeted water quality levels were applied to obtain the loading capacity which is as follows : BOD 1,891.2 kg/d, T-N 1,945.7 kg/d, T-P 131.7 kg/d. Also, the regional development load was calculated as, BOD 1,083.6 kg/d, T-N 942.2 kg/d, T-P 61.8 kg/d, which is required to be deceased :- by BOD 378.4 kg/d, T-N 198.9 kg/d, T-P 31.6 kg/d in order to safely achieve the targeted water quality in the Bunam Lake.

The purpose of this study is to analyze the mediating effect of flow in the quality of customizing e-services and customer loyalty, with a view to providing a realistic strategy for the development of fashion customizing services. For this study, a total of 489 adult women in their 20s and older participated in a survey, and the responses were analyzed using SPSS 23.0 and AMOS 23.0 . The findings of the analysis were as follows. First, the ease of use, privacy, individual designs, order status, and accuracy of orders, which were the factors of fashion customizing e-service quality, had a significant and positive impact on flow. Second, the ease of use, order status, and order accuracy, which were the factors of fashion customizing e-service quality, had a significant and positive impact on customer loyalty. Third, the flow of the fashion customizing service had a significant and positive impact on customer loyalty. Fourth, in the relationship between fashion customizing e-service quality and customer loyalty, flow had a significant mediating effect. The findings of this study are expected to be useful data for the fashion industry providing a set of criteria for optimized customizing e-services for customers.

Purpose: This study aims to conduct a systematic literature review to suitably identify wide and specific issues and topics on service quality in supply chain. Methods: This study is to investigate service quality in supply chain research using a systematic literature review methodology. In order to extract influential journals and papers, we used the SJR impact factor provided by the SCOPUS database. The collected 169 papers were analyzed using bibliometric analysis, citation analysis as well as keywords network. Results: We conducted a bibliometric analysis to identify top authors contributing to service quality in supply chain and their issues, and further examined important keywords and new emerging keywords. In addition, we extracted five influential papers by PageRank to clarify critical issues and divided into five clusters to identify topics of service quality in supply chain by using network-based approach. In order to examine comprehensive issues and topics of service quality in supply chain, we constructed a keyword network to observe difference in the classification of important keywords across network centrality measures. Conclusion: Our study reviewed literature on service quality in supply chain and explored the future directions and trends of service quality in supply chain.

Six sigma is a business management strategy and is used to improve the quality of the products and processes in many organizations. However traditional six sigma methodology, namely DMAIC, is not suitable for developing products. This paper investigates DFSS methodologies and presents a DFSS methodology for order based industry. Specifically, we suggest a customized DMADV method for order based industry and present a case study for developing a configuration optimization of the flying simulators.

Design modification of the stamping die for the upper member of a front end module carrier is carried out in order to improve the surface quality of the final product. The small inferiority induced by wrinkling near the wall of the upper member has been inspected after the draw-forming process. The finite element analysis is pursued with the whole geometry in order to consider the complicated shape. The simulation shows that the excess metal is developed by the irregular contact of the blank the tool and it remains after the final stroke. This paper proposes two guidelines for the modification. One is to add the draw-bead near the critical region in order to increase the draw-in force. The other is to modify the tool shape such as the forming shape at the wall in order to absorb the excess metal before the final stroke. Simulation results show that the proposed guidelines both guarantee the improved surface quality.

MBNQA(Malcolm Baldrige National Quality Award) was established in 1987 in order to promote the spread of TQM in U.S. Likewise, JQA(Japanese Quality Award) was set up in 1995 in order to upgrade the level of TQM activities in Japan. MBNQA and JQA are quite the same in their basic concepts, values, and the process of the examination, but they differ in the contents of the criteria. The objective of this study is to Identify the differences between MBNQA and JQA in terms of strategy planning category, Therefore, in this paper, strategy planning category is analyzed, especially its theoretical validity is examined by literature review. The major differences are as follows: JQA emphasizes strongly the evaluation process than MBNQA by requiring the measuring of the level of strategic achievement. On the other hand, in MBNQA, strategic objectives must be estimated by decision analysts techniques, scenario tools, and other statistical methodologies.

Different power quality (PQ) disturbance sources can have major impacts on the power supply grid. This study proposes, for the first time, an early warning approach to identifying PQ problems and providing early warning prompts based on the monitored data of PQ disturbance sources. To establish a steady-state power quality early warning index system, the characteristics of PQ disturbance sources are analyzed and summed up. The higher order statistics anomaly detection (HOSAD) algorithm, based on skewness and kurtosis, and hierarchical power quality early warning flow, were then used to mine limit-exceeding and abnormal data and analyze their severity. Cases studies show that the proposed approach is effective and feasible, and that it is possible to provide timely power quality early warnings for limit-exceeding and abnormal data.

Performance measurement is increasingly becoming a vital issue for promoting quality management within an organization. This research proposes a new performance measurement approach, called the Hierarchically Associated Performance Measurement, for the organizations which emphasize long term quality thrust through a balanced interface between the quality efforts of various units. The proposed approach is unique in that it considers relationships between internal quality activities and national quality award criteria and that it identifies and utilizes the quality responsibilities of functional units in order to encompass organizational roles in the evaluation process. The approach is illustrated via a numerical evaluation of a fictitious organization.
