As the new competitive environment become more global, technologically oriented and customer driven, as customers continually demand higher quality, faster response, and greater reliability of products and services, the new global market demands a more customer responsive behaviour by companies and firms have responded with innovative products and improved manufacturing processes to manufacture products. Further, the shift from traditional manufacturing and purchasing to JIT manufacturing and purchasing requires customers and suppliers to shift from adversarial relationships to strategic partnerships, and information sharing, so as to attain flexibility, reliability, and speed. SCM practices such as supplier collaboration and information sharing is considered as a key to attaining supplier network responsiveness and enhancing the product innovation and the market access time. The current research investigates the effect of SCM practices on supplier network responsiveness, the product innovation and the market access time of export companies. Thus by providing empirical evidence of the said relationships, this study offers useful guidelines for measuring and improving the supplier network responsiveness of a firm, facilitating further research in the area.

기존의 전력망에 정보기술(IT)을 융합하여 전력 공급자와 소비자가 양방향 통신을 통하여 생산과 소비 효율을 최적화할 수 있는 스마트 그리드가 개발되고 있다. 그러나 전력망에 IT 기술이 융합되면서 정보통신 인프라에서 발생하고 있는 보안 문제가 전력망에서도 그대로 재현되고 있다. 스마트 그리드와 같은 제어 시스템 보안 기술은 기존의 IT 보안 기술과는 특성상 여러 가지 차이점이 존재한다. 따라서 전력 인프라에 대한 사이버 공격을 방지하고 대응하기 위하여 보안 기술이 개발단계 초기부터 고려될 필요가 있다. 본 논문에서는 국가 주요 정보하부구조를 구성하게 될 스마트 그리드의 취약성, 특성, 보안 필요성과 요구사항 및 네트워크 설계 원칙 등에 대한 분석 결과를 제시한다.

Uncertainties are unavoidable in engineering applications. In this paper we propose an alpha reliable multi-variable network design problem under demand uncertainty. In order to decide the optimal capacity enhancement, three performance measures based on 3E(Efficiency, Equity, and Environmental) are considered. The objective is to minimize the total budget required to satisfy alpha reliability constraint of total travel time, equity ratio, and total emission, while considering the route choice behavior of network users. The problem is formulated as the chance-constrained model for application of alpha confidence level and solved as a lexicographic optimization problem to consider the multi-variable. A simulation-based genetic algorithm procedure is developed to solve this complex network design problem(NDP). A simple numerical example ispresented to illustrate the features of the proposed NDP model.

에너지에 대한 수요가 급증하게 되면서 에너지의 효율적인 운영관리가 대두되기 시작하였다. 따라서 기존 전력 및 신재생에너지 기술에 ICT 기술이 융합된 스마트그리드 기술이 전 세계적으로 각광받기 시작하였다. 스마트그리드 기술은 사용자와 공급자에게 양방향 정보교환을 통하여 더욱 합리적인 의사결정이 가능하게 하였으며, 이러한 의사결정은 에너지의 효율적인 공급과 효율적인 사용으로 인한 에너지 낭비제거 그리고 에너지 신뢰성을 향상시킬 수 있다. 그러나 이러한 장점에도 불구하고 스마트그리드의 경우 ICT 기반의 네트워크를 통하여 정보를 공유를 하고 있기 때문에 사이버 침투에 취약하다는 약점이 있다. 그래서 이러한 약점을 보완하기 위하여 보안과 관련한 연구도 활발히 진행되어야 한다. 이번 본 고에서는 스마트그리드 보안 취약점과 그에 따른 사례들을 살펴보고 이에 대한 대응방안에 대하여 간략히 기술하고자 한다.

최근 들어 보안사고의 대응 방식이 네트워크 보안이나 운영체제 보안과 같은 전통적인 방법에서 벋어나 개발생명주기보안이나 SW 공급망 보안으로 확대되고 있다. 이러한 흐름에서 주목받는 것이 BSIMM과 같은 소프트웨어 보안성숙도 모델이다. 보안성숙도 모델은 소프트웨어 시스템의 보안성 향상을 위해 관리자와 개발자가 중점을 두어야 할 부분을 스스로 평가할 수 있도록 하는 프레임워크이다. 본 고에서는 BSIMM을 통해 보안성숙도 모형이 갖는 특징을 소개하며, 이의 활용에 대해 살펴본다.

In business-to-business setting, dyadic relationships between firms are of paramount interest. Recent developments in business practice strongly suggest that to understand these business relationships, greater attention must be directed to the embedded context within which dyadic business relationships take place. As a result, it is important to develop an understanding which is to move from dyadic business relationship to business networks. The purpose of the current study is (1) to identify types of network benefits: information acquisition, access to tangible resources, cooperative support from network members, (2) to model network benefit efforts on a customer orientation for customer firm, (3) to examine the relationship between network characteristics and network benefits. Adopting resource-based view and social capital theory, the conceptual model is proposed. In order to develop and test a model, this paper was empirically to examine how network characteristics can reinforce network benefits leading to focal firm's customer orientation using 123 firms. Through structural equation modeling, this research found that (1) density influences information acquisition, access to tangible resources, cooperative support from network members, (2) centrality increases information acquisition, access to tangible resources. We also find that information acquisition, access to tangible resources, cooperative support from network members enhances focal firm's customer orientation. Finally, We discuss several theoretical and practical implications, and suggest limitations for the research and future research issue.

In the aftermath of an earthquake, seismic-damaged infrastructure systems loss estimation is the first step for the disaster response. However, lifeline systems' ability to supply service can be volatile by external factors such as disturbances of nearby facilities, and not by own physical issue. Thus, this research develops the bayesian model for probabilistic inference on common-cause and cascading failure of seismic-damaged lifeline systems. In addition, the authors present network robustness estimation metrics in the context of failure propagation. In order to quantify the functional loss and observe the effect of the mitigation plan, power and water supply system in Daegu-Gyeongbuk in South Korea is selected as case network. The simulation results show that reduction of cascading failure probability allows withstanding the external disruptions from a perspective of the robustness improvement. This research enhances the comprehensive understanding of how a single failure propagates to whole lifeline system performance and affected region after an earthquake.

Platform is considered as an alternative strategy to the traditional linear pipeline based business. Moreover, in the 4th industrial revolution period, efficiency driven pipeline business model needs to be changed to platform business. We have such success stories about platform as Apple, Google, Amazon, Uber, and so on. However, for those smaller corporations, it is not easy to find out the transformation strategy. The essence of platform business is to leverage network effect in management. Thus platform based management can be rephrased as network management across the business functions. Research on platform business is popular and related to diverse facets. But few scholars cover what the research trend of the domain is. The main purpose of this paper is to identify the research trend on platform business in Korea. To do that we first propose the analytical model for platform architecture whose components are consumers, suppliers, artifacts, and IT platform system. We conjecture that mapping of the research work on platform to the components of the model will make us understand the hidden domain of platform research. We propose three hypotheses regarding the characteristics of research and one proposition for the transitional path from pipeline to platform business model. The mapping is based on the research articles filtered from the Korea Citation Index, using keyword search. Research papers are searched through the keywords provided by authors using the word of "platform". The filtered articles are summarized in terms of the attributes such as major component of platform considered, platform type, main purpose of the research, and research method. Using the filtered data, we test the hypotheses in exploratory ways. The contribution of our research is as follows: First, based on the findings, scholars can find the areas of research on the domain: areas where research has been matured and territory where future research is actively sought. Second, the proposition provided can give business practitioners the guideline for changing their strategy from pipeline to platform oriented. This research needs to be considered as exploratory not inferential since subjective judgments are involved in data collection, classification, and interpretation of research articles.
