납석은 전남 일대를 중심으로 약 5,200만 톤이 부존 되어 있고 매년 약 80-90만 톤씩 생산되고 있어 , 국내 비금속광 중 생산액 순으로 4위 정도를 차지하고 있다. 수요의 대부분은 국내에서 조달하고, 생산량의 약 30% 정도를 수출하고 있지만 최근에는 고품위 광석을 중심으로 수입이 증가하는 추이를 보이고 있다. 방석의 국내 수요도 과거에는 내화벽돌용이 주를 이루었지만 근래에는 유리 장성유용이 가장 큰 시장역할을 하는 것으로 변모하였다. 물량만으로는 시멘트 부원료용이 가장 많지만 가격이 낮아 시장규모는 별로 크지 못하다. 시장가격을 기준으로 추정한 국내 납석시장의 규모는 수출시장을 포함할 경우 200억 원 규모이지만 소수의 상위 생산광산에서 주요한 시장을 차지하고 있어 다수의 소규모 광산들은 약 40억원 정도의 시장을 두고 경쟁하고 있다. 납석은 저가 광물인 만큼 고부가가치화를 시키려는 노력이 필요하며, 다량 부존되어 있는 저품위광을 활용하기 위한 노력과 다른 비금속광물과의 경쟁력을 지닐 수 있도록 분체물을 처리하는 분야의 연구 역시 필요할 것이다.

This paper focuses on effects that IPTV will have on domestic broadcasting market in the point of view of customers. The purpose of the paper is to present the future landscape of competitive media market when IPTV is launched, and to research how IPTV will have impact on terrestrial broadcasting, cable TV and satellite broadcasting industry. The paper integrates two known theories, such as the niche-gratification model and the value-expectancy model, to analyze competitive media market. The value expected model makes it possible to overcome the weakness of the niche-gratification model and to forecast competitiveness more accurately. According to this research, competitive power will be in the order of Cable TV, IPTV, and satellite broadcasting. Terrestrial broadcasting does not show strong competitive relationships with others statistically. As a result, Cable TV will be the most competitive medium in the future. IPTV will be stuck in the middle and can rapidly substitute for existing broadcasting services. While IPTV will severely threaten the satellite broadcasting company which has a relatively small number of subscribers, cable TV will be in a superior position to IPTV.

Customers of local monopolistic department store can switch their store more easily than ever due to the rapidly changing environment in distribution system represented by multi-store-strategy of large department stores, increase in discount store and growing non-store retailing system. Consequently, local department stores which enjoyed their business with little competition are forced to study and understand the customer switching behavior. This work is intended to understand the switching behavior characteristics of monopolistic local clepartrrent store users. For the end, previous researches are reviewed firstly, then characteristics of store-switching behavior of custorrers amid rapidly changing distribution environment are studied in view of the relations of dissatisfaction factor, switching barrier, switch intention and custorrer characteristics such as shopping orientation, variety-seeking behavior, degree of openess to competition and sociodemographics. Study shows that; 1) dissatisfaction factor is related to customer characteristics (shopping orientation and degree of openess to competition), 2) switching barrier recognition is related to customer characteristics (degree of openess to competition and sociodemographics) and dissatisfaction factor, 3) intention to switch to expected competitor is related to customer characteristics (shopping orientation, degree of openess to competition and sociodemographics) and switching barrier recognition. Accordingly, switch control strategy of the monopolistic local department store facing competitors' entry into market, must be made, specifically, in a way to understand customer characteristics and to make deliberate effort to reduce customer dissatisfaction.

필수설비에 대한 개념은 국가마다 조금씩 다르게 정의되고 있으며, 이에 따라 통신정책의 형태에 있어서도 다양성을 갖는다. 특히 캐나다의 규제기관인 CRTC는 특정 설비의 독점성 여부, 해당 설비가 경쟁사업자의 서비스제공에 있어서 필수성 여부(대체 설비의 이용 가능성), 경쟁사업자의 자체 구축 가능성 둥을 종합적으로 고려하여 필수설비를 정의하고 있다. 현재 캐나다에서 필수설비로 규정된 통신설비는 전화국 코드, 가입자 명부, 특정 구역 내에 있는 가입자선로 등이 해당된다. 한편, 필수설비의 요건은 일치하지 않으나 경쟁도입 초기에 경쟁사업자의 시장진입을 촉진하고, 경쟁사업자에게 어느 정도의 자체 통신망 구축 유인을 제공하기 위하여 도시지역의 가입자선로, 트래픽 중계 및 CCS7 전송서비스에 대해서는 5년 동안에 한하여 세분화의무를 부과하고 있다. 아울러 전주, 관로 등 지원 구조물은 이미 전기통신법 상에 관련 규정이 있다는 점에서 별도로 필수설비 규정을 부과하지 않고 있다.

Opening domestic market to international trade may enhance not only actual competition but also potential competition from foreign competitors. It seems that the competition authority has focused mainly on the actual competition (measured by the current market share) and has paid less attention to the potential competition. In this regards, this paper investigated the relation between potential foreign competition and domestic market structure. Using dynamic panel regression model, we analyzed the dynamic response of import penetration to the changes of domestic market condition in Korea as a proxy for the degree of potential foreign competition. The empirical results suggests that potential foreign competition does exist in the Korean manufacturing sector and this tendency is more stronger when the market is more concentrated. Thus, in order to effectively implement competition policy, it is necessary to consider both actual and potential competition.

For the successful implementation of ERP systems, it is very important to solve the issue of "misfits", that is, the gaps between the functionality offered by the ERP package and the required by the adopting organization. To solve the "misfit" issue, adapting to the new functionality has been recommended instead of customizing the ERP package. However, these claims are mostly based on case studies and anecdotal evidence with limited empirical justification. The purpose of this study is, therefore, to study the effect of ERP customizing on user satisfaction and firm performance. In this study, we also examine the differences in the effects of ERP customizing among three customizing types: modification, add-on development (to use 'user exit'), and add-on development (not to use 'user exit'). According to the empirical field study, we find no significant differences in user satisfaction and firm performance by overall customizing (total of three customizing types) level. However, we find significant differences in user satisfaction and firm performance by add-on development level. And the influences of customizing types on user satisfaction and firm performance are significantly affected by the functionality level offered by the ERP system and BPR level. These results indicate that ERP customizing may not always be the incorrect choice for solving the "misfit" issue.

This study empirically investigated inter-relationships among the influence factors on the adoption of e-commerce, which are classified as cause factor (i.e., perceived environmental uncertainty and competition), facilitators (i.e., perceived economic benefits, inter-organizational trust, suppliers' pressure and capability and asset specificity) and support factor (i.e., top management's support and organizational resource capability). The results of regression analyses showed that competition, inter-organizational trust, suppliers' pressure and capability, top management's support, and organizational resource capability have a positive impact on the adoption of e-commerce. In the analyses of inter-relationships among the influence factors, it was found that perceived environmental uncertainty positively influences suppliers' pressure and capability and perceived economic benefits, and competition has a positive impact on asset specificity. It was also observed that perceived economic benefits, inter-organizational trust and suppliers' pressure and capability positively affect top management's support, and inter-organizational trust and suppliers' pressure and capability have a positive impact on organizational resource capability. With mediating regression analyses, it was found that competition has an indirect impact on the adoption of e-commerce through the effect on perceived economic benefits, suppliers' pressure and capability, organizational resource capability and top management's support. The results of mediating regression analyses also showed that suppliers' pressure and capability and perceived economic benefits have indirect effects on the adoption of e-commerce through the effects on top management's support and organizational resource capability. From these results, it is concluded that intense competition causes the activation of facilitators, and the facilitators contribute to both the enhancement of top management support and the creation of organizational resource capability, which are directly linked to the adoption of e-commerce.
