  • S/W공학에서는 오랫동안 S/W의 재사용에 대해 연구해 왔지만, H/W 분야에서의 재사용처럼 활성화되진 못하였다. 이러한 가장 큰 이유로는 S/W 개발의 초기부터 재사용을 염두에 둔 개발이 아닌 일회성 개발을 하기 때문이다. 즉 개발 시작 단계인 요구사항 수집에서부터 해당 도메인에 대한 지식을 바탕으로 분석한 후 설계하지 않기 때문이다. 이는 S/W 설계에 관한 전문 지식을 갖고 있는 개발자의 부재와 더불어 주어진 개발 기간이 짧은 국내 S/W 개발 업계의 현실이 열악하기 때문이다. 그럼에도 불구하고 많은 S/W 개발 업체들은 개발기간의 단축과 개발비용의 절감을 위해 기존 S/W를 재사용하고자 한다. 재사용하고자 하는 자산이 외부의 공개 S/W든 회사 자체의 기존 자산이든 이 때 발생하는 문제가 원하는 기존 자산을 어떻게 찾아 신규 개발에 활용할 수 있는가이다. 최악의 경우에는 필요한 자산을 찾아 변경하는 것이 신규로 개발하는 것보다 더 비효율적인 경우도 발생한다. 본 논문에서는 임베디드 S/W 분야에서 S/W 자산을 재사용하기 위해 필요한 지원 시스템으로 자산들을 메타데이터로 등록하고 검색할 수 있는 지원 도구를 설계하고자 한다.

  • Purpose - The purpose of this study is to grasp the concept, characteristics and application status of sharing economy, and to derive a research model based on sharing economic service, and to analyze factors and influences of consumers' intention to reuse of sharing economy. Research design, data, and methodology - The questionnaires were created to examine variables for practical and theoretical implications. After pilot survey, conducted for 24 days from March 10th to April 2st in 2017, total numbers were 377. But 330 copies were used for the analysis with IBM SPSS Statistics 23.0 and IBM SPSS AMOS 23.0. The structural equation model was applied for this. Results - First, sharing economic services remain at an early stage, but it is meaningful to identify the revenue mechanism of the business model of the sharing economic platform. Second, in this study, it is meaningful that we systematized the theoretical structure by examining existing studies on the characteristics of the sharing economic service and consumer characteristics, and by examining empirically. Third, Satisfaction and Reliability are related to the characteristics of Sharing Economic Service (Security, Convenience, Discount, Sharing, Social Interaction), Consumer Characteristics (Personal Innovation, Word-of-Mouth) It is meaningful to broaden the understanding of the factors by verifying the mediating effect. Fourth, the sharing economy business is meaningful in that it is a new consumption trend that changes the meaning of consumption to consumers. Gradually, more and more people are recalling that purchasing something is not consumption, but sharing and borrowing is also consumption. In other words, through the sharing economy, consumers can experience more products and services, have more choices, and are expected to have a positive impact on economic growth by increasing the utilization of idle resources. Conclusions - Currently, the sharing economy is growing rapidly all over the world. Therefore, in the subsequent study, it is necessary to compare Korea and China's sharing economy and study the cultural and social characteristics of Korea and China. In particular, I think that steady research is necessary for more precise and specific direction on the influence of the shared economy.

  • In recent years, the development of ubiquitous computing technology as vital information anytime, anywhere to monitor and manage the demand for U-healthcare services is increasing. Accordingly, remote blood sugar management, remote blood pressure management, and research on U-healthcare service have been very active. But, the existing U-healthcare service monitoring devices and services has been implemented in different operating platforms and programing languages which are provided by diverse application service providers. For this reason, the users have difficulty in receiving diverse U-healthcare services. In this paper, SOA-based U-healthcare monitoring system has been designed and implemented. Through implementation, it is confirmed that the proposed SOA based U-healthcare monitoring system can increase the reuse of each service component to make it easier to reconstruct the structure of the new services.

  • With the active smartphones user exceeding 500 million by the end of 2014, China has now become the largest smartphone market in the world. Smartphone companies provide variety of information through a range of applications, such as communications, entertainment, games, and so on. There were many studies conducted about the user acceptance and continuous intention of mobile service. However, it is still not quite clear what factors attract people to reuse smartphone in China. This paper examines the continuous intention of smartphone about Chinese customers. This study incorporates perceived enjoyment as a additional construct into a extended TAM model, by integrating a hedonic service of smartphone. We propose a research model that reflects the individual characteristics and usage contexts of smartphone, such as innovativeness, social influence, and service quality, and analyze the structural relationship between the main variables through empirical study. This study empirically investigated a research model and conducted a survey of smartphone service users in China. Our study proved that perceived enjoyment has a positive influence on continuous intention to use smartphone services. This paper provides the managers an insight that smartphone companies should take more consideration on how to provide more enjoyable service and attract customers to reuse their services.
