Diverse types of malicious code such as evasive Server-side Polymorphic are developed and distributed in third party open markets. The suspicious new type of polymorphic malware has the ability to actively change and morph its internal data dynamically. As a result, it is very hard to detect this type of suspicious transaction as an evidence of Server-side polymorphic mobile malware because its C&C server was shut downed or an IP address of remote controlling C&C server was changed irregularly. Therefore, we implemented Simulated C&C Server to aggregate activated events perfectly from various Server-side polymorphic mobile malware. Using proposed Simulated C&C Server, we can proof completely and classify veiled server-side polymorphic malicious code more clearly.

This study aimed to investigate how such retailers as department stores, large discount stores, book wholesalers, and clothing wholesalers used information technology for the QR strategy and whether the QR strategy had an effect on performance with a focus on the pipeline strategy. For this purpose, the QR strategy was divided into transaction efficiency, supplier partnership, and customer detail strategy. The differences in performance and information technology were analyzed according to the fit of the pipeline strategy, such as internal focus, supplier focus, and customer focus, the business strategy which were used by the retailers. And, an attempt was made to investigate whether performance was raised according to the level of adopting information technology. The results can be summarized as allows. First, the adaptive level of information technology had an effect on performance. But, seeing that the explanatory power of the regression analysis on the effect of the adaptive level of information technology on performance was shown to be very weak, it is judged that the level of QR information technology in the responding firms was very low compared to that of foreign firms. Second, information technology used by the retailers included universal product code, bar coding, customer database, and information utilities. It was shown that the group of firms seeking the transaction efficiency QR strategy and the internal focus pipeline strategy had the higher level of information technology than the retailers seeking other customer detail QR strategy and the customer focus pipeline strategy and the retailers with inconsistent strategy. This indicates that the firm seeking to raise its internal efficiency has a high level of using information technology. At the end of the paper, managerial implication and future research directions were discussed.

As South Korean large business groups, also known as Chaebol, have broadened their influence in the domestic economy, it is important to analyze the influence of internal transactions among Chaebol affiliates on their performance. In this paper, relationship between internal transactions and efficiency of Chaebol affiliates has been analyzed. Top five Chaebol groups in South Korea are selected; they include Samsung, Hyundai Motors, LG, SK, and Lotte group. Based on internal transactions among affiliates, social networks are constructed for each Chaebol group to analyze centrality, network structures and cliques. Data Envelopment Analysis (DEA) was conducted to examine the efficiency of the Chaebol affiliates. Then, correlations between the degree centrality and the efficiency of Chaebol affiliates were analyzed, and the network structures of Chaebol groups are presented. The result shows that positive correlations between degree centrality and efficiency are observed among four Chaebol Groups. This paper shows that the Social Network Analysis (SNA) techniques can be used in the empirical research for the analysis of internal transactions of Chaebol groups.

본 논문은 거배비용분석 이론의 포괄적 이해를 돕기 위한 하나의 방법으로 거래비용분석법의 구성요소 중의 하나인 "거래비용"에 대한 개념검토를 목적으로 하고 있다. 유통경로 지배구조 현상을 규명하기 위한 하나의 방법으로 거래비용 분석의 개념적 틀을 적용한 지도 벌써 수십 년이 경과되었다. 본 연구의 출발점은 Williamson(1975)이 개념적 틀에서 제시한 자산특유성(asset specificity)을 어떠한 형태로 정의하고 있는지?, 기존의 선행연구들에서는 어떠한 형태로 자산특유성을 설명하고 있으며, 선행연구들에서는 자산특유성 개념의 조작적 정의를 어떠한 형태로 정의하고 있는지? 에 대한 물음에서 출발하고 있다. 본 연구를 통해 거래비용 이론이 완전 자유 경쟁체제가 아닌 통제 경제체제에서도 적용 가능한 것이냐 하는 것이다. 거래비용 이론은 Williamson(1975)이 제시한 개념적 틀을 그대로 적용할 것이 아니라 해당 산업내지는 국가 체제에 따라 수정 보완하여 적용하는 것이 바람직하다는 결론이다. 기존의 거래비용(자산특유성)에 대한 연구방향을 종합하여 요약하면 크게 네 가지 방향으로 나누어진다고 볼 수 있다. 첫째는 기업이 제품의 유통과 관련하여 기업이 특유자산을 보유하고 있는 판매 대리인을 이용할 것인지, 아니면 자사의 고용인을 이용할 것인지에 대한 연구의 흐름이다. 둘째, 원료의 공급에 있어 기업이 특유자산을 보유하고 불확실성이 큰 경우 기업이 직접 제조할 것인지 아니면 외부 공급자로 부터 구매할 것인지에 대한 의사결정의 문제를 다루고 연구의 흐름이다. 셋째는 기업이 해외 시장 또는 서비스 시장 진출 시 지사의 사용 할 것인지 아니면 현지 대리인의 이용에 관한 문제를 다루는 연구의 흐름이다. 넷째는 거래비용이론이 가지는 기본 가정의 한계를 지적하고 거래비용이론의 확장을 시도하는 연구의 흐름이다. 거래비용분석이 갖는 한계점으로는 첫째, 기존의 연구들은 Williamson(1975)이 제시한 개념들을 이용하여 단순히 유통경로 현상을 규명하는데 만 치중하고 있다는 것이다. 둘째, 유통경로 구성원들이 거래비용(자산특유성)때문에 다양한 거래구조를 형성했다면 그에 따른 명확한 성과가 있어야 하는데, Heide와 John(1988)의 지적에서 처럼 거래비용분석의 기본 가정에 관한 실증적 연구가 매우 애매 한다는 것이다. 셋째, 기업이 특유자산(불확실성)을 보유하고 있는 거래를 내부화한다고 가정하고 있으나 내부화에 대한 명확한 설명이 제시되어 있지 않다는 것이다. 다섯째, 거래비용 이론은 완전자유경쟁체제에 적합한 이론이라 할 수 있으며 통제경제 내지는 계획경제 체제하에서는 적용하기가 부적절한다. 향후 연구를 위한 제언으로는 경제구조와 산업구조의 차이에서 발생하는 현상으로 분석할 수 있으며, 다양한 산업구조에 거래비용분석을 적용할 필요성이 존재한다. 따라서 거래비용분석에서 제시하고 있는 거래비용에 대한 명확한 정의가 필요하다.

As society's relience on computerized information systems to support a wide range of activities proliferates, the long recognized importance for adequate data quality becomes imperative. Furthermore, current trends in information systems such as dispersal of the data resource together with its management have increased the difficulty of maintaining suitable levels of data integrity. Especially, the importance of adequate accounting (transaction) data quality has been long recognized and many procedures (extensive and often elaborate checks and controls) to prevent errors in accounting systems have been introduced and developed. Nevertheless, over time, even in the best maintained systems, deficiencies in stored data will develop. In order to maintain the accuracy and reliability of accounting data at certain level, periodic internal checks and error corrections (internal audits) are required as a part of internal control system. In this paper we develop a general data quality degradation (error accumulation ) and cost model for an account in which we have both error occurrences and error amounts and provide a closed form of optimal audit timing in terms of the number of transactions that should occur before an internal audit should be initiated. This paper also considers the cost- effectiveness of various audit types and different error prevention efforts and suggests how to select the most economical audit type and error prevention method.

In this paper, we propose a establishment of system level environment to exploit PC system with SSD (Solid State Disk) by using TLM (Transaction Level Modeling) method with SystemC language. The reason why we choose this modeling method is that it eases RTL (Register Transfer Level) modeling burdens and we can accurately estimate the performance about different architectural changes. Also, it provides simulation speed which is relatively faster than RTL modeling method. The baseline architectural platform we implemented showed that SSD's internal transfer time is a dominant factor, so we need to improve that part and it is expected to be a good simulator to measure the system's overall performance by exploiting SSD's internal architectures.
