Numerous types of SIS (Strategic Information Systems) have been developed based on certain strategic frameworks. This paper reviews those traditional SIS frameworks, and points out the ignorance of customer-orientation. Also, this paper addresses a new SIS framework based on customer-orientation: i.e., transaction visibility. This paper proposes that computer systems can increase customer value by changing visibility in transactions with customers. Relevant cases are also presented for sake of clear understanding of this new framework.

This paper proposes a new concept of inter-organizational systems (IOS) visibility, considering the key role of IOS in IT-enabled supply chain (SC) cooperation. Further, antecedents and consequences IOS visibility have been studied. Antecedents of IOS visibility are identified from the two conflicting theories of inter-organizational relationships, i.e., RDT(resource dependence theory) and RV(relational view). Investigating SC cooperation from the perspectives of both partners (buyers and suppliers) is important, especially when channel partners depend on each other and when asymmetries in IOS visibility can exist. Hence, this study attempts to accommodate both partners' perspectives in IOS visibility and to look into the consequences of IOS visibility from each participant's perspective.

웹의 보편화로 인하여 수많은 데이터가 산출되고 있으나 데이터 관리를 위한 메타데이터 표준은 특정 도메인에 제한적이고 너무 광범위하게 정의되어 있어 데이터가 비효율적으로 관리되고 있는 실정이다. 이를 해결하기 위해 RDF를 활용하여 자원간의 관계를 정의하고 있으나, RDF의 특성에 적합한 편집도구가 전무한 상태이다. 따라서 본 논문에서는 RDF 저작도구를 설계 및 구현함으로써 RDF를 기반으로 메타데이터의 유효성 검증을 수행하고, 기술된 자원간의 관계를 가시적으로 분석할 수 있는 노드 앤 아크 다이어그램을 지원하며, 웹자원을 N-triple로 표현하여 데이터의 효율적인 관리 및 분석을 가능하게 하였다.

This paper presents GDOCF(Government Document Enterprise Architecture Framework) based on the direction of EA(Enterprise Architecture) framework to build GDOCEA. The construction of EA for GDOC offered various types of information technology Platform which advanced the interoperability between Government Information Systems. In addition, it insured the interoperability between the e-Government Initiatives and helped a consistent management for information resource. As a result, MOGAHA could support a policy decision and capital investment plan for information. Also, all the information needed for the operation and management of GDOC has been being referenced, shared and utilized as EA repository. Eventually Pilot EA would be a corner stone to build EA master plan considering all the information systems in MOGAHA.

The purpose of this study is to find out the positive effects of the block chain when applied to the logistics industry and what legal problems should be solved to apply the block chain to the logistics industry. As a result of the study, it was found that the block chain can create the streamlining document work, increasing visibility, improving transaction reliability, activating Internet of things, and expanding smart contract. However, in order to apply the block chain to the logistics industry, have also confirmed that the scope of electronic transactions, international distribution of electronic bill of lading, and legal supplementation related to personal information protection are necessary. It is meaningful to confirm the applicability in the logistics industry, the positive effect and the legal problem, but it is necessary to study the problem from the practical point of view in the hereafter research.

The degree of informational asymmetry relating to the expiration of index derivatives is usually increased as an expiration day of index derivatives approaches. The increase in the degree of informational asymmetry may have some effects on trading behavior of investors. To examine what the effects look like, 'life cycle of index derivatives' in this study is defined as three adjacent periods around expiration day: pre-expiration period(a week before the expiration day), post-expiration period(a week after the expiration day), and remaining period. It is inspected whether stock investor's trading behavior is changed according to the life cycle of KOSPI200 derivatives and what the reason of the changing behavior is. We have four results. First, trading behavior of each investor group is categorized into three patterns: ㄱ-pattern, L-pattern and U-pattern. The level of trading activity is low for pre-expiration period and normal for other periods in the ㄱ-pattern. L-pattern means that the level of trading activity is high for post-expiration period and normal for other periods. In the U-pattern, the trading activity is reduced for remaining period compared to other periods. Second, individual investors have ㄱ-pattern of trading large stocks according to the life cycle of KOSPI200 index futures while they show U-pattern according to the life cycle of KOSPI200 index options. Their trading behavior is consistent with the prediction of Foster and Viswanathan(1990)'s model for strategic liquidity investors. Third, trading pattern of foreign investors in relation to life cycle of index derivatives is partially explained by the model, but trading pattern of institutional investors has nothing to do with the predictions of the model.

The change in the management environment of the logistics industry in the era of global competition is becoming an era in which customers choose companies. Differentiation from competitors through the provision of products and services suitable for customers As customers' choices change depending on their superiority, companies are constantly striving to receive or retain customers' choices. Ultimately, this competitive structure can be seen as the importance of long-term relationship building. Therefore, in this study, we examined how factors related to transaction characteristics performed by logistics companies for customer satisfaction in the transaction relationship between cargo companies and shippers affect performance and long-term transaction intentions. First, we derived the factors of logistics service, cost, logistics infrastructure, and company competency, which are transaction characteristics factors of a logistics company that must be specifically realized for customer satisfaction in transactions between logistics companies. Second, we analyzed how the transaction characteristics factors of a logistics company affect the company's performance, and finally, how the company's performance factors affect long-term transaction intentions. As a result of empirical analysis, there were no statistically significant results on the relationship between transaction characteristics and performance of logistics companies, which can be attributed to the small size of the logistics companies that were the sample. In other words, logistics companies that do not have sufficient capacity to provide services at low prices have no choice but to engage in constant bleeding competition. It can be seen that it reflects the characteristics of the industry. On the other hand, the relationship between corporate performance factors and long-term transaction intention was found to have a positive relationship. The higher the level of partnership with logistics companies and visible financial performance is, the higher the transaction will be in the future, and the more the transaction volume will be gradually increased. And even if it costs a little more, it can be seen that the intention to continue trading is greatly expressed.
