Several scholars in South Korea have predicted that maintenance costs of social infrastructure will sharply increase from the mid-2020s, and cause budgetary deficits among facilities management agencies. Interest in infrastructure asset management (IAM) is rising as a solution to such problem. In this study, an information system for asset valuation that reflects the salvage value and deferred cost of social infrastructure based on WBS (work breakdown structure) was developed in consideration of IAM. To reuse the construction cost information such as the acquisition cost, the interconnection between CBS (cost breakdown structure) and WBS was considered. Furthermore, asset valuation information was developed with XML schema to facilitate the exchange and reuse of the information among project participants.

디지털홈 서비스는 기존 PC에서 제공하던 서비스와 차별화된 서비스를 실용화 하지 못하고 있는 이유 중에 하나는 오프라인에서 제공하던 의료, 법률, 교육 등의 서비스를 가정에 맞게 직접 제공하고 있지 못하기 때문이다. 이를 위하여 본 논문에서는 온라인에서 의사, 변호사와 안전하게 거래할 수 있도록 국가자격 인증기반을 구축하고자 이에 필수적인 검증 가능한 온라인 자격증 발급을 위하여 기존 공인인증서에 자격필드를 추가하거나, 기존 공인인증서를 그대로 사용하거나, 별도의 자격인증서를 발급하는 등 세 가지 발급모델을 제시한다. 또한 이러한 세 가지 발급모델의 장단점을 비교 분석하여 향후 자격인증기반 구축할 때 선택할 수 있는 기준을 제시한다. 마지막으로 기 제시된 세 가지 발급 모델 중에 자격필드가 추가된 공인인증서를 이용하여 의료서비스(E-Health)를 받는 서비스 모델 시나리오를 제안하고자 한다.

The influence factors on the development of information technology(IT) infrastructure for knowledge management(KM) were not empirically investigated and identified. This study empirically examines the relationships among strategic performance measurement systems(SPMS), organizational learning, the strategic alignment of business strategy with information systems(IS) strategy, which is the necessary condition to provide the kinds of knowledge required for the successful realization of business strategy, and the active construction of IT infrastructure for KM. This study demonstrates that SPMS directly affects the organizational learning, with which the members of an organization acquire the types of knowledge about strategic goals or objectives and the ways attaining these goals, and indirectly influences the IS strategic alignment through organizational learning. Thus, the alignment between business strategy and IS strategy can be facilitated and activated by the adoption and implementation of SPMS. According to the results of this study, it is observed that the IS strategic alignment and organizational learning positively affect the activation of the development of KM IT infrastructure in a firm. The results of this study also shows that the construction of KM IT infrastructure, which supports the realization of KM activities, such as knowledge creation, transfer and sharing, can enhance the strategic position of a firm, and the intensified competitiveness of a firm can lead to the improvement of performance.

연구개발과정에서의 필수요소인 연구장비의 공동활용 및 효율적인 구축을 위해 한국에서는 국가예산으로 구축된 장비정보를 필수적으로 등록하도록 하고 있다. 등록정보의 다양한 활용(중복성 검토, 성능예측, 대체장비추천)을 위해 본 연구에서는 현재 유사장비검색기법에 대해 분석하고 유사도 산출 방법을 제시하였다. 이를 통해 자연어 상태인 장비정보에서 키워드를 추출하여 LSA 기법을 적용하면 키워드간의 유사도산출 및 장비정보 간 유사도 분석이 가능함을 확인하였으며 향후 연구장비분류정보를 접목하여 적용할 경우 의미있는 유사도 산출 및 이를 활용한 다양한 서비스가 가능 할 것으로 예측된다.

코로나19 사태는 정보통신의 기초가 되는 바탕 또는 토대인 정보통신기반의 필요성을 재인식하는 계기가 된다는 문제의식에 바탕을 두고 주로 법학적 관점의 문헌 조사와 규범적 고찰을 통하여 코로나19 사태에서 정보통신기반의 중요성을 확인하고 정보통신기반 구축·보호에서 국가의 책임을 구현하는 제도적 방안이 무엇인지를 총론적 관점에서 살펴보았다. 정보통신기반은 코로나19 대응에서 중요한 역할을 하였으며 포스트 코로나 시대의 디지털 전환의 주요 관건이다. 이에 따라 국가는 정보통신기반의 구축과 보호에 대한 책임이 있다. 국가의 정보통신기반 구축·보호 책임에서 제도적 방안은 중요한 의미를 지니며 법률적 차원의 대응뿐만 아니라 정보통신기반 구축·보호에 관한 국가목표규정을 형성하는 헌법적 차원의 대응도 필요할 수 있다. 이러한 연구결과는 관련 개별 법령에 대한 세부적인 연구의 기본 전제와 방향성을 제시한다.

전기차 충전 인프라에서는 충전 및 결제 데이터를 포함하여 다양한 데이터가 전송되기 때문에 안전한 전기차 충전 인프라를 구축하기 위해서는 이에 대한 보안 연구가 요구된다. 그렇지만 기존에 진행된 연구들은 전기차 충전을 위한 충전 인프라 보다는 전력 계통 인프라와 같은 스마트 그리드 관련 보안 연구가 주를 이루고 있다. 또한 충전 인프라 관련 연구는 아직 부족한 현실이며, 위협모델링과 같은 체계적인 방법론을 이용한 연구는 아직 진행되고 있지 않다. 따라서 안전한 전기차 충전 인프라의 구축을 위해 위협모델링을 적용하여 보안 위협을 식별하고 보안요구사항을 체계적으로 분석하는 것이 필요하다. 본 논문에서는 Data Flow Diagram, STRIDE, Attack Tree를 활용한 위협모델링을 이용하여 충전 인프라에서 발생 가능한 위협을 정확히 식별하고 객관적인 보안요구사항을 도출하여 전기차 충전 인프라를 분석한다.

In order to survive in a competitive environment, many companies are taking much interest in building IT infrastructure and are investing in that area. But, despite of all the interest and investments, many companies are unsatisfied and confused because of the lack of guidance and understandings of IT infrastructure. Therefore the purpose of this study is to prove that the level of IT usage is different according to organizational characteristics and industrial categories, and to give a guideline to companies' planning on newly building IT infrastructure. In conclusion, companies newly planning on building IT infrastructure should consider the amount of information technology functional uses according to the organizational characteristics and industrial category and they follow the below guidelines. On building the IT infrastructure the organization having the characteristics of formalization should consider and provide the standardization function first. The companies having the characteristics of decentralization should consider and provider firstly the application and communication function. And the companies having the characteristics of specialization should consider and provider the security function.

The success of new product development is a key factor for getting competitive advantages. Marketing research has been investigating marketing capability, manufacturing technical capability, cross-functional integration, market knowledge competence, market orientation, and competitive environment as the key success factors of new product development. Recently, the role of IT infrastructure in enhancing new product advantage is assumed in the literature. However, the empirical studies on the role of IT infrastructure are lacking. The purpose of this study is to empirically exam the impacts of IT infrastructure on new product competitive advantage. In this study, IT infrastructure is conceptualized as the flexibility of IT infrastructure. Based on previous research, a conceptual model is established by incorporating the direct impact of IT infrastructure flexibility and its indirect impact through the key success factors on new product development. To empirically test the research model, data are surveyed from a pair of IS department and Marketing department of 92 consumer goods manufacturers. By employing PLS technique, the measurement reliability and reliability of research variables are tested and the path analysis is conducted to do the hypothesis testing. The path analysis shows that IT infrastructure flexibility has no direct effect on new product advantage, However, the indirect effect of IT infrastructure is found, which is mediated by marketing capability, manufacturing technical capability, cross-functional integration, and market orientation respectively. Hence, The flexible IT infrastructure increases cross-functional integration (H1), market orientation (H3), marketing capability (H5), and manufacturing technical capability (H6). All success factors of new product development excepts for competitive environment have a positive association with new product competitive advantages (from H10 to H14). Finally, the path from IT infrastructure flexibility to cross-functional integration, to market orientation, to market knowledge capability, and to new product advantage is found as the strongest path. These results indicate that the flexible IT infrastructure enhances information sharing with multiple departments and collaboration within a distributed innovation environment. The collaboration among departments positively affects the level of customer and competitor intelligence. The ability to obtain knowledge about customers and competitors makes firms to adapt to a changing environment quickly and to respond to customers' demands adequately. The flexible IT infrastructure also enhances the capability of organization to more rapidly respond to the changes in product design resulting in faster product development and reduced costs. In addition to, it enhances marketing capability by the two-way communications with customers and the analyses of various kinds of customer data. In brief, the finding of this study suggests that the flexible IT infrastructure allows many firms to pursue sustained new product competitive advantages. This study advances research on IT infrastructure in two important aspects. First, by Integrating marketing research and IS research, this study develops a conceptual model on the role of IT infrastructure in enhancing new product advantage. Second, it empirically finds the indirect impacts of IT infrastructure on new product advantage, which confirms the potential for the IS field to contribute to new product development research. The limitations of this study are also discussed to provide research directions for future research.
