Purpose - Environmental issues, climatic changes, and greenhouse gases are problems to be solved at a global level. With an increased emphasis on the environmental and social responsibility of the management of companies, the manner in which companies approach quality-oriented culture and their individual sustainability management are being discussed as truly important issues to help them secure their competitiveness and growth strategies. This study proposes strategic directions to help manufacturers not only in expanding their competitive quality-oriented company culture but also in strengthening their sustainability management abilities. This study conducts a literature review and empirical research to examine how significantly the variables of a quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. Research design, data, and methodology - To verify research models and hypotheses, the study examined 170 companies using a questionnaire survey conducted over six weeks, and involved the performance of data analysis on 146 samples. Questionnaire responses were calibrated based on a Likert scale. The study used the Smart PLS 2.0 program designed for PLS (partial least squares), an analysis instrument of SEM (structural equation modeling). The study then verified empirical research hypotheses working on reliability analysis, validity analysis, factorial analysis, and path analysis. Results - Among the nine hypotheses, four are accepted and the rest are rejected. A quality-oriented company culture focusing on customer-centered management significantly influenced the maintainability management performance of environmental integrity and social responsibility, while economic profitability was dismissed. A process-focused quality-oriented company culture was significantly concerned with economic profitability but not with environmental integrity or social responsibility. A supply-chain cooperative company culture had a significant effect on economic profitability but not on environmental integrity or social responsibility. Conclusion - This study proposes strategic directions to help manufacturers expand their competitive quality-oriented company culture as well as strengthen abilities with sustainability management. It conducts a literature review and empirical research to examine how significantly the variables of quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. There are two main conclusions. First, companies should consider the need for social responsibility management and environmental transparent management-focused maintainability management as avenues to create new markets and business, thereby helping the companies secure a reputation for having a customer and process-centered quality-oriented company culture by creating shared values between supply chains and enabling win-win situations through cooperation. Second, we are marching towards a creative win-win era from a society of conflicts and ruptures. Companies should understand that social responsibility management and supply chain management (SCM)-focused cooperation are the foundations of sustainable development, as they try to improve their culture while pursuing both win-win relationships with interested parties and equity in various conflictive relations.

소비자의 구매 행위가 합리적이고 실용적인 방향으로 변화하는데 힘입어 할인점업계는 급속한 외형적인 성장과 함께 경쟁도 치열하다. 따라서 업계는 그 해결책으로 차별화와 수익성을 동시에 실현 시킬 수 있는 유통업체 브랜드(PB: Private Brand) 개발에 사활을 걸고 있다. 또한 치열한 경쟁 환경 하에서 생존하기 위해서는 고객만족을 넘어서 고객충성도를 높이는 것이 효과적인 방법임이 밝혀짐에 따라 PB가 고객충성도를 제고시키기 위한 전략적인 도구로 사용되고 있다. PB 이용 고객의 충성도를 높이려면 우선 고객집단의 특성을 파악해서 소비자가 지각하는 품질수준을 우선적으로 맞춰줘야 고객만족과 고객신뢰를 얻을 수 있고 결과적으로 고객충성도로 유도할 수 있다. 이에 본 연구는 지각된 품질에 영향을 미치는 선행요인과 고객충성도에 영향을 미치는 변수들 간의 관계에 대한 체계적인 분석결과를 제시하기 위해 선행연구에서 검증된 인과관계를 기반으로 연구모형과 연구가설을 설정했고, 주요 연구결과는 다음과 같다. 기업명성, 브랜드명성, 제품경험, 브랜드친숙도가 높을수록 지각된 품질이 높아지고, 지각된 품질이 높을수록 고객만족, 고객신뢰, 고객충성도가 높아지며, 고객만족과 고객신뢰가 높을수록 고객충성도가 높아지는 것으로 조사되었다. 또한 기업명성이 지각된 품질에 미치는 영향력은 PB가 NB보다 높게 나타난 반면 브랜드명성과 브랜드친숙도가 지각된 품질에 미치는 영향력은 NB가 PB보다 높게 나타났다. 이러한 실증분석 결과는 지각된 품질에 영향을 미치는 선행요인과 결과요인에 대한 보다 명확한 이해를 바탕으로 실무자가 마케팅 활동을 하는데 유용하게 활용할 수 있을 것이다.

The purpose of this thesis is to provide basic information of efficient flow line arrangement, which results from examining the factors of route choice with a focus on the store' space elements and pedestrian activity patterns in the outlets. The route tracking is applied to grasp pedestrian activity patterns, therefore, a concrete analysis into influential factors of the space structure arrangement and forms on route choice. The route tracking is a means to understand pedestrian activity patterns by establishing an unrecognizable space and examining every route in the investigating area for pedestrian activity pattern research. Three sample stores have different systems in the ground plan structures, the escalator location and the directions. The analysis focuses on the booth arrangement and shopping patterns. In conclusion, route choice of the customers and the structure of the space are quite closely related and affect the quality of shopping. This can suggest evidence for the need of the space structure to meet the pedestrian activity patterns.

We propose a model for the line expansion problem in the AMOLED (Active Matrix Organic Light Emitting Diodes) industry, which now faces market uncertainty: for example, changing customer needs, technological development path, etc. We focus on the optimal investment time and size of the AMOLED production lines. In particular, employed here is the ROV (Real Options Valuation) model to show how to capture the value of line expansion and to determine the optimal investment time. The ROV framework provides a systematic procedure to quantify an expected outcome of a flexible decision which is not possible in the frame of the traditional NPV (Net Present Value) approach. Furthermore, we also use Monte Carlo simulation to measure the uncertainty associated with the line expansion decision; Monte Carlo simulation estimates the volatility of a decision alternative. Lastly, we present a scenario planning to be conducted for what-if analysis of the ROV model.

In this paper, we suggest the exact perturbation analysis(Exact_PA) technique with respect to the buffer storage in tandem queueing networks, through which the optimal buffer storage design problem is considered. The discrete event dynamic equations for the departure time of a customer are presented together with the basic properties of Full Out(FO) and No Input(NI) with respect to the buffer storage. The new perturbation rules with respect to the buffer storage are suggested, from which the exact perturbed path can be obtained. The optimal buffer storage problem is presented by introducing a performance measure consisting of the throughput and the buffer storage cost. An optimization algorithm maximizing this performance measure is derived by using the Exact_PA technique. The proposed perturbation analysis technique and the optimization algorithm are validated by numerical examples.

Customers want to have more convenient and comfortable vehicle. Motor-on-caliper EPB(Electrical Parking Brake) System is one of the new systems for customer's convenience. It is applied for Midsize vehicle for reducing weight/price compared to cable puller type EPB. In this paper we studied sound quality improvement of motor-on-caliper EPB system. We developed the sound quality index and suggested the interior sound quality target value. To meet the target value cascading target was also suggested. EPB motor vibration level & sound radiation level, vibro-acoustic transfer function level from EPB to interior was defined. To find out effective way of sound quality improvement and find cascading target, TPA(Transfer Path Analysis) was carried out.

This study has empirically analyzed the competitive strategies of the Korean component manufacturers. To differentiate the competitive strategies, the study employed two indexes: degree of support from customer firms and degree of internal innovation process. The performance measures include cost, quality, delivery and flexibility. 115 questionnaires were finally collected from the Korean part manufacturers and used for the final analyses. ANOVA, Chi-squared tests and t-tests were employed for statistical analyses. There are two major findings in this study. First, both internal innovation and external support from customers are equally important to improve manufacturing competitiveness of Korean component manufacturers. Second, strategic path to improve competitiveness of Korean component manufacturers is as follows: focusing on internal innovation ${\rightarrow}$ seeking for formal relationship with customers ${\rightarrow}$ pursuing external support from customers.

Because of increasing demand for safety of the power transformer, the seismic qualification process in accordance with the standard of IEEE Std 693-1997 is essentially required by customer. Dynamic analysis method and static analysis method were used to qualify the seismic withstanding of the power transformer at high seismic level. Maximum stress was detected at the connection between the main structure and appendages, and maximum displacement was detected at the point of appendage's end tip. Load path and substructure system can be considered as important elements to prevent over stress and over displacement.
