The managerial environment of automobile industry has been rapidly changing, mainly with the tighter standard of legal and environmental regulations, the pressure of cost reduction from the end-user, the various functional improvements of vehicles, and the globalization management. In order to survive in this complicate circumstances, the automakers have strongly pursued the mutual collaboration with the suppliers, especially tier-1, for the optimal selection of parts/materials and the assembly manufacturing processes of the new model development. They prepare the early involvement program for the suppliers during the conceptual design stage, and implement the win-win strategy of technology development activity, in order to improve the value creation. This study considers the strategic technology management of automotive steel sheets makers on the aspects of strategy, processes, human & physical resources, and organization structure. It also suggests the corporate strategies of steel mills, in order to obtain the technology competence.

한국은 선진국의 원자력 산업 침체와는 대조적으로 아직도 활발하게 원자력발전소를 건설 운영하고 있으며 앞으로도 이와 같은 원자력발전을 적극 고려한 전력에너지 정책기조를 유지하려고 하고 있다. 한국의 경제규모는 세계 10위권에 진입하려 하고 있으며 OECD에 가입하는 등 국가의 전반적인 위상이 향상되었으며 현재 국제 원자력 시장에서 한국은 매우 중요한 고객인 동시에 수혜적 입장에서 벗어난 잠재적인 공급자라는 점이 널리 알려져 있다. 그러나 한국의 원자력산업을 세계화하기 위한 기반은 아직 미약한 상태에 머물러 있다. 이는 한국이 원자력발전소를 도입하기 시작한 1970년대초 이래로 기술국산화란 산업적 측면을 강조하여 원자력정책을 다루어 오면서 국제정치 및 국제교역 측면을 중시하지 않았기 때문이다. 이러한 배경에서 본 논문은 한국이 국제 원자력 통상 분야에서 활동 영역을 넓히고 국제 원자력정책 결정 과정에 보다 많은 영향력을 행사하기 위한 전략을 제시하고 있다.

The M&A of firms has been emerged as the effective means of fast diversification and growth in dynamic environment. However, the empirical research about M&A in Korea has not been implemented rich due to the difficulty of obtaining M&A data. In this research, we empirically investigate the relationships among M&A, environment and firms' performance focused on Korean manufacturing firms, understanding the current practice of M&A in Korea. We use the Manufacturing Productivity Panel Survey Data, which are collected by Korea Productivity Center in 2013. The sample size is 575 and the sample is divided into M&A group and non-M&A group. We conduct logit analysis with the independent variables of environment factors (munificence, dynamic, uncertainty), and firms' performance (sales growth, ROS, labor productivity and Inventory turnover), and dependent variable of M&A group or non M&A group. The results show that M&A is closely related to environment feature and firm performance: M&A firms are likely to be the higher munificence and dynamic and the lower sales growth and higher profitability than non-M&A group. In addition, we also examine the characteristics of firms by M&A types (competitors, customer/supplier and firms from unrelated industry). These results imply that if firms confront the pressure of uncertainty (dynamic) and the lower growth, they tend to choose M&A. Futhermore, to profoundly understand the behavior of firms about M&A, it is required to classify the M&A firms by merge types.

Today, many manufacturing companies realize that collaboration is crucial for their survival. Especially, in the perspective of quality, the importance of collaboration is emphasized because economic loss increases exponentially while defective parts go through the process in supply chain. However, the manufacturing companies are facing two main difficulties in implementing collaborative relationships with their suppliers. First, it is difficult for the suppliers to produce reliable products due to their obsolete facilities. The problem gets worse for second- or third-tire vendors. Second, the companies experience the lack of universally understandable set of terminology and effective methodologies for knowledge representation. Ontology is one of the best approaches to expressing and processing a domain knowledge. In this paper, we propose the manufacturing ontology-based quality prediction framework to represent and share the knowledge of industrial environment and to predict product quality in manufacturing processes. In addition, we develop the ontology-based quality prediction system based on the proposed framework. We carried out a series of experiments for an injection molding process at an automotive part supplier. The experimental results demonstrated that the proposed framework and system can be successfully applicable in manufacturing industry.

Recently, an advanced raw material supplying system in diecasting industry that molten metal produced by the raw material supplier can be directly delivered to the diecasting shops was proposed. It was known to have advantages of reducing melting process cost and improving working environment. However, for its successful mass production, the development of high insulation ladle is inevitable. In this study, the optimal mixing ratio of $SiO_2-Al_2O_3$ was investigated and the high insulation ladle with computer simulation result was built in a prototype and evaluated. The prototype which has refractory wall of $SiO_233%-Al_2O_3$ 35%-CaO 33% showed high insulation sufficient for carrying the Al molten metal for 138 minutes. Gas quantity result and SEM-EDS analysis on the melt poured in the ladle also showed extremely low level of 0.028 cc / 100 g and no penetration of Al molten metal into the refractory wall, satisfying the requirements for mass production.

The increasing application of electronic equipment has heightened the interest in power quality in recent years because there are economic impacts on utilities, customers, and suppliers of load equipment. The power quality would impose result in severe damage on many industrial customers. As having been supplied many kinds of electronic devices such as computer and communication equipment, automation equipment and various kinds of control devices etc., it comes to be more and more difficult to maintain the clean power quality. According to the restructuring in electricity industry the power quality may be treated as goods as contract terms and regulation elements between power supplier and consumer in the near future. Under the above environment, the power quality should be monitored for all day long with appropriate devices which is possible to measure and record the associated power quality data to prove each responsibility for the impacts when disputes arise due to power quality problems power quality problems are occurred. In this paper the authors propose some functions to be considered and system configuration to monitor the associated power quality elements in developing the web based power quality monitoring system.

The purpose of this study is to propose and test a model of customer retention in Internet shopping malls when switching barriers and comprehensive customer value exist in terms of economic and experiential aspects. The literature about customer retention propose that switching barriers are important factors other than satisfaction influencing customers' intention to remain with a specific supplier. The switching barriers mean anything that makes customers' defection difficult or costly and are consisted of perceived switching costs, attractiveness of alternatives and virtual relationships. The Customer Value Scale by Mathwick(2001) is applied to this study as economic value, shopping efficiency, service excellence, aesthetic appeal and playfulness(Zeithaml, 1988; Holbrook, 1994). The analyses showed partial support for the affirmative effect of customer values and switching costs and full support for the affirmative Influence of satisfaction on repurchase intention in the Internet shopping mall environment. But the attractiveness of alternatives and virtual relationship did not have a significant Influence like the result of Jones(1998)'s study of the service industry.

The purposes of this study are to investigate the formation and the change of apparel retail structure historically with the viewpoint that the retail structure is affected by the process of economic development. This study was done by literature research method and the result of this study is the following. The tailor and seamstress shops, the first clothing shops in Korea, were replaced by ready-made shops, because mass production system which had developed with the industrialization of Korea increased the advantage of economy of scale compared to handicrafts individual one. After that, the production system of apparel industry had been efficient continuously, while retail system had not. The retailing of famous brand apparel conducted by exclusive franchise store caused supplier oriented markets where the opinion and the desire of consumers were not reflected. While the retailing of the unknown brand apparel handled by small retail stores were inefficient. As the apparel industry matured in 1990s, various types of new stores appeared such as specialty stores, discount stores, TV home shopping, internet shopping, outlet malls, and big fashion stores in Dongdeamoon. These new stores have features of seeking profits in mass merchandising. As these large retail stores grow, the apparel retail structure of Korea is changing from a fragmented market to a vertically integrated one. This change is shown by the decrease of stores per inhabitants. With the change of environment, the apparel retail system which has lagged behind comparatively is expected to develop into more efficient system based on the large capital investment which raise the advantage of economy of scale.
