In order for the users (shipping firms and shippers) and suppliers (stevedoring firms) in the container terminal industry to win-win, it is necessary to have some appropriate diverse market conditions for the industry. This study analyses the basic conditions and demand and supply characteristics of the industry and investigates the market performance of Busan container ports. First, this article analyses the basic characteristics of demand and supply. As the demand characteristics, there are five ones such as 1) exogeneity of demand, 2) function as export/import transportation and hub for transshipment, 3) increase of users' bargaining power, 4) high substituting elasticity, 5) reduction of volume growth. As the supply characteristics, there are seven ones such as 1) inelasticity of supply, 2) homogeneity of stevedoring services, 3) over-supply, 4) adoption of cutting-edge stevedoring technology, 5) scale economy and impossibility of storage, 6) labor market rigidity, 7) enhancing port's role in SCM. In addition, this study conducts the so-called structure-conduct-performance analysis. For the structure analysis, 1) lacks of scale economy in stevedoring companies, 2) high entry barrier, 3) strengthening of shipping firms' bargaining power, 4) transitory permission scheme for tariff are analyzed. For the conduct analysis, 1) price discrimination between export/import and transshipment, 2) mid-term length of terminal use contract, 3) continuous investment in equipment, 4) low level of cooperation among terminal operating firms are derived. For the performance analysis, 1) inequality in profitability, 2) reduction of export/import cost, 3) delay in adopting cutting-edge technology, 4) idle equipment are analyzed. Following this logical flow, the hypothesis that the market structure influences the market conduct is tested based on the actual dataset. As a future agenda in the conclusion, this article recommends the so-called port industrial policy.

As the Korean construction market in the apartment housing has changed to a housing consumer focused market, interest and importance on efficient use and management on existing buildings has increased rather than demand for new buildings. Interest of housing consumers on apartment house quality has increased in this market paradigm, and this spontaneously is connected to quality flaw related defect disputes and lawsuits that the importance of defect diagnosis has continuously increased. This defect diagnosis is directly connected to maintenance charges in defect dispute and lawsuit processes that rather objective and highly credible progress of duty is required. However, most defect diagnosis firms today that progress defect diagnosis are using different diagnosis methods and depend on the experience of experienced professionals that there is no standardized defect diagnosis process. Therefore, the purpose of this study is to provide common defect diagnosis process model for defect diagnosis firms utilizing the BPMN (Business Process Modeling Notation) modeling method. It is expected that this will contribute to professional and reliable task performances of concerned defect diagnosis workers. Furthermore, it is expected that design lawsuit damage will be substantially reduced by standardizing defect diagnosis processes.

This study investigates how characteristics in the value-chain industrial cluster affect the R&D investment and the output of firms in each industries. For this, we try to extract the inter-industrial networking structure from the input-output table in which 17 manufacturing sectors are included. In particular, we will give shape to the "unit structure" which shows the intermediary flows of goods and services between industries in order to get an unit of final demand in a certain industry. Using this "unit structure", we can try the inter-industrial networking analysis and get some indices of centrality and centralization related to the characteristics of each industries in the value-chain industrial cluster. The results show that the centrality in the value-chain industrial cluster does not have any consequence for the R&D investment and the output in each industries. However, there is a correlation between the centralization in the value-chain industrial cluster and the R&D investment and the output of firms in each industries. These results may be very suggestive in bringing up a new frame of industrial cluster policy in a macro level.

This essay examines the marketing of Fishermen's Cooperative in Korea, and in particular considers the marketing channel of fisheries products, No company can perform by itself all the activities involved in the production and distribution of its products and services to its final markets. It must work with other firm to get the job done. Thus marketing channel firms of the fisheries products include primarily the Fishermen's Cooperative the licensed dealers and tile merchant middlemen, The goal of marketing is in matching of segments of supply and demand. Every producer seeks to the link the marketing channel firms that will help it accomplish its objective best. Therefore this study surveys the three types of marketing channels through tile central market That. is, they are a marketing channel through the terminal market, a marketing channel through the fishermen's cooperative terminal market, and a marketing channel through the private fish market. Consequently the Fishermen's Cooperative can choose to improve in any of tile marketing channel as follows: \circled1 The Fishermen's Cooperative is nominated wholesaler in the terminal market. \circled2 It is abolished to sell by double auction in the production district terminal market and the consuming city terminal market of Fishermen's Coopertive. \circled3 The steady wholesalers in private fish market are entitled to the licensed dealers. \circled4 The Fishermen's Cooperative sponsored voluntary chains join with retailer, supermarkets, consumers' society. Therefore the study of marketing channel of fisheries products can appropriately referred to satisfying needs and wants through exchange process.

Recently many firms operate a cross-docking center in addition to run a distribution center to reduce logistics costs and maintain or enhance logistics service. However, it is true that many firms just operate their cross-docking centers as they are without any change, in spite of that the location of the cross-docking center should be changed and operated when the location of distribution center is changed and moved. This study presents the method that re-selects the location of the cross-docking center when the existing distribution center is changed. Describing the operation environment to apply the cross-docking system and the selection criteria of the cross-docking center under the environment of changeable logistics network, we define the simulation model which can analyze and select the location of the cross-docking center applied to a logistics field. The simulation model presents experiential algorithm selecting the location with the data of the demand point such as volume, transportation costs, and delivery distance.

This research empirically investigated the influence factors on the activation of environmental innovations (EI) in Korean manufacturing firms. In this study, external factors (compulsory demand, government regulation, normative pressure and imitative pressure) and internal factors (environmental resources, top management support, integration of environmental tasks, capabilities of environmental personnel, and environmental strategy/environmental management systems) were totally considered. The results of a multiple regression analysis showed that influence factors such as top management support, environmental resources and integration of environmental tasks have a significant and positive impact on levels of EI. However, the effects of external factors were not statistically significant. We also examined whether capabilities of environmental personnel as well as environmental resources, which are directly related with degrees of EI, have a moderating impact on relationships between other internal factors and levels of EI. With a subgroup analysis, the moderating role of abilities of environmental personnel were empirically confirmed. Through a multiple regression analysis, the direct effects of external factors on the adoption or construction of internal factors were demonstrated. The effects of government regulation, normative pressure and imitative pressure on internal factors were significant and positive. It was also found that external factors have indirect effects on EI through internal factors. Finally, the results of multiple regression analyses indicated that EI positively influences the achievement of environmental competitive benefits, and environmental competitive advantages can improve the organizational performance of a firm.

As electronic commerce is growing to be a part of everyday business life for companies, enterprises are required to establish the appropriate strategy to effectively realize their business visions. The correct choice of strategy enables organizations to make efficient use of internal resources and adjust to the external environment, affecting their performance. The nature of the firms' strategy has been currently focused on the new business model such as e-commerce. In the beginning of e-commerce, the decreasing cost of business transactions was a major benefit affecting its success. However, e-commerce firms are currently facing new advanced information technology, various business models and serious competition. To deal with these new challenges, there is an increasing demand for right strategy direction to effectively and efficiently manage a corporation's internal resources and external environments that are related to electronic commerce. Moreover, it is necessary both to set up the feasible strategy direction and to evaluate its outcome. The purpose of this study attempts to provide appropriate e-commerce strategy, which is well matched with e-commerce performance, as the different strategies affect different results of e-commerce. On the basis of the results of this research, we can see that the strategies selected by e-commerce companies differ according to the e-commerce type and firm's size.

The research tries to find appropriate nations and cities of the international supporting centers according to Korean firms' requests. It also tries to find out proper designs of governance structure and strategic and operational control system of the center. Two methods are used to find out Korean firms' requests. One is the expert interviews and the other is the questionnaire survey. The email survey is sent to 120 firms of IT service, package software, telecom facilities and broadcasting equipment industries. Their opinions in addition to interview results are used as a basis of selecting potential regions for new centers and types of their services. According to survey results, southeast asia is the most preferred region and Indonesia, Vietnam, Thailand, Malaysia and Singapore are selected as potential nations for a location of the center in southeast asia. However, the survey result is not fully agreed with the interviewees' opinions. The interviewees tell that there are not much demand in nations with low purchasing power and low IT industry level. That is, Indonesia and Vietnam are not proper places for the centers.

The purpose of this study is to examine an immoral effectiveness decrease by information access monitoring between ethical dilemma and unethical information-sharing behavior. Firms are raising the demand of confidential information management and are highlighting the ethical awareness of organizational members. The individuals in organization are concerned information sharing for future-oriented social networking. To prevent their immoral behavior, Firms should consider investing the information access monitoring. This system is aiming at log verification of movement, storage and deletion on information and will reduce an ethical conflict and unethical behavior on employees. I used the structural equation methodology for this empirical study. The research model constructs the voluntary and involuntary dilemma of information sharing on the two independent-variables, the unethical information behavior and the improper networking reinforcement on the two dependent-variables and the information access monitoring the one mediating-variables. This model tests the power effect of direct path, indirect path and total path. According to the study, the two ethical dilemma of information sharing provided a high influence to the unethical sharing action and to the inappropriate social networking strengthens. However, the mediating role of information access monitoring shows the effect weakens of independent and dependent variables. Thus, the mediating variables appeared to be important for the controlling role of an unethical behavior and improper social networking. Ultimately, The firms will need to invest the information access monitoring for a compulsory ethics behavior of organizational members. In addition, this can hinder networking enhancements for future opportunistic behaviors.

This paper empirically examines effects of exporting on employment over the period 2000-2007 for Korean listed and non-listed manufacturing firms. The paper employs the dynamic panel model of labor demand and controls for simultaneity of the exports and real wages using a two step random effect Tobit-DPD (Dynamic Panel Data) procedure. Our empirical results suggest that surprisingly, there is no robust evidence for employment effects of exporting of Korea's large firms and small-medium sized firms during the sample period after Korean financial crisis. This implies that Korean exporting patterns have been changed in a way that exporting highly capital intensive goods leads to importing more intermediate goods and thus to countervailing the employment effects of exporting. This suggests that expansion of exporting by lowering exporting prices through the bilateral FTA might not be helpful to enhancing employment in Korea.
