This study aims to investigate the effects of market commonality and resource similarity on price competition and the recursive consequences in the Korean lodging market. Price comparison among hotels in the same geographic market has been facilitated through the development of information technology, rendering little search cost of consumers. While the literature implies the heterogeneous price attack and response among hotels, a limited number of empirical researches focus on the asymmetric and recursive pattern in the competitive dynamics. This study empirically examines the price interactions in the Korean lodging market based on the theoretical framework of competitive price interactions and countervailing power. Demonstrating superiority to the spatial lag model and the ordinary least squares in the estimation, the results from spatial error model suggest that the hotels with longer operational history pose an asymmetric impact on the price of the newer hotels. The asymmetry is also found in chain hotels over the independent, further implying the possibility of predatory pricing. The findings of this study provide the evidence of a hierarchical structure in the price competition, with different countervailing power by the resources of the hotels. Theoretical and managerial implications are discussed, with suggestions for future study.

According to Resource Dependence theory, an organization's behavior and strategy is affected by external resources. An organization has diverse resources interacting with environment. Because organization cannot focus on all those resources, it concentrates on its critical resources. In market environment, firm responds to other firms by controlling their internal critical resources or manages interdependency with environment to get market share. Thus Firm should choose best behavior and strategy when internal and external resources are change. When new brand enters, incumbents might change their strategy to protect their market share depending on critical value. More precisely, incumbents sharing market with entrant respond, but incumbents having competitive internal resources do not. In this article, we study incumbent's responses to a new brand entry and long-term effect. We show that how incumbents change their price strategy in reaction to the new brand' entry and also show these responses vary depending on interdependency of internal resources and external environments and ownership.

컴포넌트 기반 소프트웨어 개발 (CBD) 기술은 재사용 가능한 컴포넌트를 조합하여 효율적으로 소프트웨어를 개발함으로써 개발 노력과 상품화 시간을 줄여주는 새로운 기술로 정착되고 있다. 이러한 CBD 컴포넌트는 한 도메인의 표준이나 공통적인 기능을 제공하여야 재사용성이 높아진다. 특히, 공통성 안의 미세한 가변적인 부분도 모델링하고, 이 가변성을 각 어플리케이션의 특성에 적합하게 특화 할 수 있도록 설계되어야 한다. 기존의 CBD 방법론에서도 이 중요성이 강조되고 있지만, 체계적이며 구체적인 개발 프로세스, 적용 지침 및 산출물 양식의 제공이 미흡하여, 도메인 컴포넌트의 개발은 비체계적인 프로세스와 개발자의 경험에 의존해 왔다. 본 논문은 컴포넌트 설계를 위한 체계적인 프로세스와 기법을 제안한다. 이 프로세스는 여러 단계와 활동으로 구성되며, 각 활동에 대한 세부 지침과 표준 양식도 포함하여 보다 효과적인 컴포넌트 개발을 도모한다. 제안된 기법의 실효성 검증을 위하여 금융 도메인에 적용한 사례연구를 제시하며, 다른 기법들과의 비교 평가도 다룬다. CBD의 공통 컴포넌트 개발에 제안된 프로세스와 지침의 사용함으로써 보다 재사용성과 적용성이 높은 컴포넌트가 비용 및 시간에 있어서 효율적으로 개발될 것으로 기대된다.

Software and Systems Product Line(SSPL) is a paradigm that has been developed and applied by European Union(EU) to achieve the productivity and competitiveness of EU industries on the world market. It is not just a simple system or software development methodology, but a sophisticated technology requiring capabilities for a high level of mass customization, platforms, processes and convergence of software and systems. EU has applied SSPL for the five selected industrial sectors including aerospace, automobile, medical equipment, consumer electronics and telecommunication equipment since 1990s and led the way to other industry sectors to stimulate the application of SSPL from 2006. In order for Korea to secure competitiveness in the manufacturing and service industries in the competitive borderless market, it is essential to gain the high level of capabilities for software development and convergence of software and systems. SSPL can be a powerful means to achieve this end. This paper discusses the paradigmatic concept of SSPL, how EU's major industries and companies have secured competitiveness through SSPL, key capabilities that are necessary for successful institutionalization of SSPL in Korea, and finally suggestions on core strategies to materialize the benefits of SSPL for Korea.

This study aimed to understand the current status of practice for sustainability in luxury fashion brands. A total of five luxury brands (Louis Vuitton, Hermès, Gucci, Burberry, and Prada) were selected. Each company's official website, sustainability reports, and articles on sustainability practices were compiled. In addition, analysis was performed based on criteria of sustainability such as environmental, social, economical, and cultural dimensions. As a result, the biggest commonality of the five brands was that they promoted the most active change in the environment. These brands tried to reduce energy consumption in materials and production processes. Among them, Burberry, Gucci, and Louis Vuitton had their own departments for sustainability. However, there were differences in strategies of activities between brands for social, economical, and cultural sustainability. Among the five companies, Burberry and Gucci pursued sustainability strategies the most aggressively. They separated their sustainability strategies in terms of environmental, social, economical, and cultural aspects and shared them with consumers. A set of outcomes for the plan were provided as objective data. The sustainable management strategy has become a key strategy for long-term growth of the luxury brand market. To survive in the market, luxury brands should elaborate sustainable management strategies and actively share them with consumers.

S/W product line is a S/W product or a set of S/W system, which has common functions. We can develop a specific S/W product, which satisfiesrequirements of a particular market segment and a mission in a specific domain by reusing the core asset such as the developed S/W architecture through the S/W product line. S/W development methodology based on the S/W product line can develop a S/W more easily and fast by reusing the developed S/W core asset. An advanced country of S/W technology selects S/W product line as a core field of S/W production technology, and support technology development. In case of USA, CMU/SEI (Carnegie Mellon University / Software Engineering Institute) developed product-line framework 4.0 together with the industry and the Ministry of National Defense. Europe is supporting the development of product line technology through ITEA(IT for European Advancement) program. In this paper, we aim to construct reference architecture of S/W product line for production of the S/W product line.

Recently, automotive companies have invested in vehicle weight reduction and clean car development because of oil price rises and environmental problems. In particular, USA car makers have developed the vehicle spending 1 liter per 34km complying with PNGV(Partnership for a new generation of vehicle) and Europe car makers have developed the vehicle spending 3 liters per 100km. The USA government announced "The green car policy" in order to boost production of more fuel effective cars in 2009. According to the policy, it will be restricted to sell the car which spends more than 1 liter per 14.9km by 2020. To satisfy the current situations on automotive market, hydroforming technology has widely adapted vehicle structures such as engine cradle, chassis frame, A pillar, radiator support, etc. However, automotive companies have to consider formability and performance to improve and maximize the benefit from this technology in advance of detail design. The paper deals with one of the vehicle weight reduction methods using tube hydroforming technology and platform commonality in front suspension. FEA simulation is also introduced to evaluate hydro-formability and NVH performance at the beginning of design stage which is the best way to reduce the failure cost.
