This paper analyzed the management quality activities and performance based on industrial types. We divided the business into four industrial types, manufacturing industry, service industry, medical institution and public enterprise. We analyzed the differences of the elements of management quality in industrial types. The results show that leadership, measurement, analysis and knowledge management and workforce focus categories are not significant and strategic planning, customer and market focus, process management and performance categories are significant. This paper proposes the directions of management quality activities and performance according to industrial types based on these results.

The picking process in distribution center is one of the most difficult and time-consuming process. The improvement of picking productivity is a core element which decides efficiency of the distribution center. The time to shipping on vehicles from receiving depends on the arrangement of items or picking methods. The Pick to Light system typically is used to improve the efficiency of order picking. In some cases the layout design of Pick to Light system has been performed rather than scientific analysis by a common experience. Therefore, this study analyzed the impact of picking performance by the zone arrangement method in order picking process of Pick to Light system.

The purpose of this study is to examine the green management evaluation criteria and Employee Awareness and analyze their impact on management performance. A survey was conducted using a questionnaire form that was given to companies with fewer than 300 regular workers and less than 30 billion won in sales. The three-step mediated effect analysis proposed by Baran and Kenny was performed to verify the roles of the parameters. The research results are summarized as follows. First, awareness of greenhouse gases and environmental pollution play a mediating role affecting the management performance. Second, awareness of harmful chemical substances play a mediating role affecting the management performance. Lastly, The survey subjects were limited to SMEs in Chungcheong province and thus, this may not be applicable to all companies.

The airport processes are restricted by some limits of performance objects as size of airport, ability of human resources, capacity of facilities and operational rules. These limitations make passenger handling difficult when passenger numbers increase. In order to solve this problem, we modeled the airport process and analyzed departure passenger arrival, scheduled security manpower under specific customer service level maintenance with mixed integer programming and validate the efficiency with simulation with adapting smart airport framework. We concluded that the airport management with information techniques can reduce waiting time within security and immigration process.

With advancements of quay side equipments and technologies, the bottleneck of port operations has moved from quay side to yard side. The yard management of a port has significant influences on the competitiveness of a port in the global shipping network. The research area of yard management has attracted a lot of attentions from both the academia and the industrial practitioners. This paper gives a comprehensive review for the studies on the yard management in container terminals. From three aspects, i.e., yard cranes management, yard vehicles management, and yard spaces management, this paper reports the advances in these three areas. Some future directions on the yard management researches are also discussed. The purpose of this paper is to stimulate more practically relevant researches in this emerging area.

This study investigates the current situation of the ISO 9000 manufacturing industry in Taiwan, analyzing the business influence of ISO 9000 and the relation of the influence to industry-related characteristics. The study utilized polling and was approached from six aspects, using 26 indicator items to evaluate performance. The six approaches consisted of business management, finance management, production management, human resources management, marketing management, and a company's overall situation. Methods used to analyze the collected data were mainly drawn from descriptive statistics e.g.. the T test and analysis of single factors with variation. The study found that $96.6\%$ of the industry thought that the introduction of the ISO 9000 series was somewhat beneficial. The 26 indicator items among the six approaches were proved substantially effective by the T test. It was obvious that the effect of the ISO 9000 series industry standard was beneficial and helpful to the manufacturing industry.

This paper presents a non-linear control chart based on support vector machine regression (SVM-R) to improve the accuracy of fault detection of cyclic signals. The proposed algorithm consists of the following two steps. First, the center line of the control chart is constructed by using SVM-R. Second, we calculate control limits by variances that are estimated by perpendicular and normal line of the center line. For performance evaluation, we apply proposed algorithm to the industrial data of the chemical vapor deposition process which is one of the semiconductor processes. The proposed method has better fault detection performance than other existing method
