As electronic commerce establishes itself as a viable and competitive channel, this research compares the attractiveness of online and offline purchase from a transaction cost perspective. In the process, we propose a framework that integrates transaction cost with purchase decision process and product type. Specifically, the paper proposes and tests hypotheses regarding the difference between online and offline channels with respect to the transaction costs incurred in each stage of the purchase decision process. These differences are further compared across different product types categorized according to the FCB Grid. A total of 24 hypotheses were tested by conducting a questionnaire survey on university students. The results showed that 19 out of 24 hypotheses were supported. Following a detailed presentation of the analysis results, the paper concludes by discussing the academic and managerial implications of the findings.

Similar software is often developed with the Clone-And-Own (CAO) approach that copies and modifies existing artifacts. The CAO approach is considered as a bad practice because it makes maintenance difficult as the number of cloned products increases. Software product line engineering is a methodology that can solve the issue of the CAO approach by developing a product family through systematic reuse. Migrating product families that have been developed with the CAO approach to the product line engineering begins with finding, integrating, and building them as reusable assets. However, cloning occurs at various levels from directories to code lines, and their structures can be changed. This makes it difficult to build product line code base simply by finding clones. Successful migration thus requires unifying the source code's file path, class name, and method signature. This paper proposes a clustering method that identifies a set of similar codes scattered across product variants and some of their method full paths are different, so path unification is necessary. In order to show the effectiveness of the proposed method, we conducted an experiment using the Apo Games product line, which has evolved with the CAO approach. As a result, the average precision of clustering performed without preprocessing was 0.91 and the number of identified common clusters was 0, whereas our method showed 0.98 and 15 respectively.

UPS(Uninterruptible Power Supply)는 우리말로는 무정전전원장치(無停電電源裝置)라고 하는데, 정전(停電 : Stoppage of Electric Current)과 같은 전원장애(電源障碍)가 발생한 경우 UPS에 접속되어 잇는 기기에 지속적으로 전원을 공급하는 장치를 말한다. UPS방식에는 상시 인버터방식, 상시 상용방식, 라인 인터랙티브방식의 세가지가 있다.

Software product line (SPL) engineering is a reuse paradigm that helps organizations increase productivity and improve product quality by developing product from reusable core assets. In SPL, product configuration is the process of selecting the desired features and feature attributes for a given product from a feature model. In order to develop a successful product, feature and feature attribute selection that can achieve the product goal is important. There can be thousands of features and feature attributes resulting in myriads of configurations and finding the best configuration efficiently is a hard task. This paper proposes a systematic process for feature-based product configuration. To support development of a product that satisfys all product goals(business goals and quality goals), a model showing how feature and feature attribute combinations are related to product goals is included and a method for deriving an optimal product configuration using the model is proposed.

Clone-and-own reuse is an approach to creating new software variants by copying and modifying existing software products. A family of legacy software products developed by clone-and-own reuse often requires high maintenance cost and tends to be error-prone due to patch-ups without refactoring and structural degradation. To overcome these problems, many organizations that have used clone-and-own reuse now want to migrate their legacy products to software product line (SPL) for more systematic reuse and management of software asset. However, with most of existing methods, variation points are embedded directly into design and code rather than modeled and managed separately; variation points are not created ("engineered") systematically based on a variability model. This approach causes the following problems: it is difficult to understand the relationships between variation points, thus it is hard to maintain such code and the asset tends to become error-prone as it evolves. Also, when SPL evolves, design/code assets tend to be modified directly in an ad-hoc manner rather than engineered systematically with appropriate refactoring. To address these problems, we propose a feature-oriented method for extracting a SPL asset from a family of legacy applications. With the approach, we identify and model variation points and their relationships in a feature model separate from implementation, and then extract and manage a SPL asset from legacy applications based on the feature model. We have applied the method to a family of legacy Notepad++ products and demonstrated the feasibility of the method.

본 연구는 JIT생산시스템에서 혼합조립라인에 대한 제품순서게획에 대한 연구이다. 본 연구에서 고려하는 조립라인을 효과적으로 수행하기 위해서는 서로 다른 제품들을 조립하기 위한 제품순서가 결정되어야 한다. 필요한 제품을 적시에 적당한 양만큼 생산하는 JIT생산시스템에서의 제품 순서계획의 목적은 라인에서 소비 되는 모든 부품들의 소비율을 일정하게 유지시키는 것이다. 본 연구에서는 부품소비율을 일정하게 유지시키 면서 동시에 순서계획수립시 계획파괴를 줄일수 있도록 그룹개념을 이용하여 순서계획문제를 정식화하고 이 에 대한 해법을 제시하였다. 본 연구에서 개발한 해법의 우수성을 평가하기 위해 총변동과 순서계획의 파괴빈도에 대한 실험을 통하여 기존해법과 비교한 결과 본 연구의 해법이 우수한 결과를 제공하였다.

Chinese consumers get more interests in the brands which show the consumers with th trust rather than the those which provide consumers with excessive information on brand. Accordingly, this study aimed to find out that the antecedents of brand authenticity such as brand consistency, continuity, individuality, authority, ethics affect the brand aura through brand authenticity and surveyed data from a total 400 Chinese consumers for the analysis. As a result, this article is summarized as followings. First, brand continuity, individuality, authority affected brand authenticity but brand consistency and ethics did not have a direct effect on brand authenticity. Second, brand authenticity had positive effect on brand aura. This study provides information on the antecedents of brand authenticity of Chinese consumers. Further, it will provide meaning suggestion point of the importance of brand authenticity in establishing of brand aura.
