The purpose of this study is to provide some new perspectives in explaining how supply chain capabilities can create a sustained competitive advantage for the firm. In particular, drawing from the dynamic capability theory and supply chain management literature, we propose that supply chain capabilities can serve as a catalyst in transforming resources into higher value for a firm. The model consists of two independent variables (IT capability, and relationship management capability), one mediating variable (supply chain capability), and a dependent variable (performance). To test the model, the research subjects are selected from 1,000 KOSDAQ (Korean Securities Dealers Automated Quotations, Korean) firms. The result shows that IT capability is the most important determinants of supply chain capabilities, and relationship management capability have positive impact to supply chain capabilities. supply chain capabilities also has positive impact on corporate performance.

스마트기기가 보편화되고 있고 무선랜의 사용량이 증가함에 따라 로그 AP를 이용한 공격 가능성도 높아지고 있다. 로그 AP에 접속할 경우, 로그 AP는 중간자 공격(Man-in-the-middle attack)을 수행할 수 있으므로, 매우 쉽게 개인 정보를 획득할 수 있게 된다. 다양한 종류의 로그 AP를 탐지하는 방법에 관해 많은 연구가 이루어지고 있고, 이 논문에서는 그 중, 정상 AP에 무선으로 연결하고 이를 중계해서 자신은 정상 AP의 SSID를 보여줌으로써 정상 AP인 것처럼 하여 사용자를 속이는 로그 AP를 탐지하는 방법을 제안한다. 이런 로그 AP를 탐지하는 데 있어서 기계학습 알고리즘의 일종인 SVM(Support Vector Machine)을 사용하여, 사용자의 환경에 따라 자동으로 탐지 기준을 설정하여 로그 AP를 90% 이상의 확률로 탐지하는 알고리즘을 제안하고, 이의 성능을 실험을 통해 입증한다. Widespread use of smartphones and wireless LAN accompany a threat called rogue AP. When a user connects to a rogue AP, the rogue AP can mount the man-in-the-middle attack against the user, so it can easily acquire user’s private information. Many researches have been conducted on how to detect a various kinds of rogue APs, and in this paper, we are going to propose an algorithm to identify and detect a rogue AP that impersonates a regular AP by showing a regular AP’s SSID and connecting to a regular AP. User is deceived easily because the rogue AP’s SSID looks the same as that of a regular AP. To detect this type of rogue APs, we use a machine learning algorithm called SVM(Support Vector Machine). Our algorithm detects rogue APs with more than 90% accuracy, and also adjusts automatically detection criteria. We show the performance of our algorithm by experiments.

The purpose of this study is to find the determinants of SCM systems success in the perspective of vendor companies. In developing the research model, we have focused on selecting the success factors appropriate for the vendors through reviewing past researches and on developing more accurate success measures. The model consists of three independent variables (IT HR capability, process innovation, and collaboration relationship), one mediating variable (IS Integration), and a dependent variable (organization performance). The results show that process innovation is the most important determinant of organization performance, and collaboration relationship is the most important influencing factor of IS integration with full mediating effect. The practice characteristic of SCM systems has direct and indirect effect on organization performance from the viewpoint of private industrial network.

Currently, business environment is characterized by fast and dramatic changes in customer expectations. Deep competition and high technology are increasingly creating high level of market uncertainty in turbulent environment. To respond current situation, firms are seeking to enhance dynamic capabilities across the supply chain. A key emphasis of supply chain management (SCM) is to improve supply chain dynamic capabilities between trading partners through IT competence. Most firms increasingly rely on information technology (IT) to improve the process integration and the performance of supply chain. IT competence provides fundamental support to supply chain dynamic capabilities and supply chain performance. And IT competence can facilitate the development of higher-order supply chain dynamic capabilities. Supply chain dynamic capabilities (SCDC) refer to the ability of an organization to identify, utilize, and assimilate both internal and external resources information to facilitate the entire supply chain activities in turbulent environment. The primary objective of this study is to provide a new perspective in explaining how IT competence and IT-enabled supply chain dynamic capability can create a sustained competitive advantage and performance for supply chain of the organization. This research reviewed existing literatures related to IT competence and supply chain dynamic capabilities, and classified them according to resource-based view (RBV) and dynamic capabilities theory (DCT). Dynamic capability theory follows the resource-based view in term of relevant guidance for future research of strategic management. The dynamic capability has been proposed as the firm`s ability to integrate, build, and reconfigure internal and external competences to address a higher level of turbulent environment. This study provides a conceptual framework to explore the relationships among IT competence (IT flexibility, IT management), and supply chain dynamic capabilities (information exchange, supply chain coordination, IT integration, supply chain responsiveness), and supply chain performance. Hypotheses are tested on survey data collected from 116 respondents charged in supply chain operation of manufacturing organizations. This study develops valid and reliable instruments to measure the sub-dimensions of IT competence and supply chain dynamic capabilities, and we applied SEM (structural equation modeling) to test causal relationships between research variables. Empirical results show that IT competence does not have significant influence on supply chain performance, however, IT competence has significant influence on supply chain performance through supply chain dynamic capabilities. Especially, supply chain dynamic capabilities have significant relationship to supply chain performance. This finding suggests that IT competence is a driver to facilitate the development of supply chain dynamic capabilities, and that supply chain dynamic capability is a determinant to improve supply chain performance of an organization. The contribution of this study is to provide the importance and the necessity for the notion of supply chain dynamic capability that enhances supply chain performance.
