  • As the distributed simulation system has been developed in the defense modeling and simulation, interoperability among heterogeneous simulators is essential to achieve the objectives of the distributed simulation system. However, the interoperability has been a problem to synchronize synthetic environment among many heterogeneous simulators that utilize different environmental data formats. SEDRIS (Synthetic Environmental Data Representation and Interchange Specification) was initiated to solve the problem of the interoperability. SEDRIS provides a standard mechanism to promote data interchange and reusability, and it represents all environmental things from ocean, land and atmosphere to the universe. Although SEDRIS provides various advantages as a standard environmental data format, applying of SEDRIS has been hindered by its broadness and complexity. The main objective of this paper is to explain application development process to improve SEDRIS usability for the atmosphere and ocean. The developed application of this paper provides auto-generation of SEDRIS data with minimum user's input, and the auto-generated SEDRIS data is also visualized and verified by the application.

  • 최근 네트웍의 보급과 지리정보의 활용이 증가하면서 효과적인 지리정보의 검색과 접근에 대한 중요성이 강조되고 있다. 하지만 기존의 GIS 데이터는 지리적으로 분리된 여러 부서나 조직에서 생성 및 관리되고 있으며, 공간 정보 유통을 위한 클리어링하우스 등이 서로 다른 DBMS 상에서 독자적인 스키마를 가지고 개발되어 있다. 이러한 이질적인 구조와 구현 환경으로 인해 일반 사용자들이 서로 다른 GIS 데이터베이스를 접근하여 검색하는데 많은 어려움이 따르고 있다. 본 연구에서는 OMG의 메타데이터 교환 표준인 XMI로 표현된 이질적인 GIS 데이터베이스의 메타데이터를 통하여 사용자에게 각 데이터베이스의 구현 환경과 스키마에 독립적인 공간 데이터를 검색 기능을 제공하는 검색 시스템을 구현하였다.

  • The purpose of this study was to examine factors contributing to financial resources interchange type and amount of the middle aged and the elderly household. For this study, the 6th KLIPS data was used, and sample size was 1,679 households including those with head of household being over the age of 50. Statistical analysis was conducted to examine frequency, percentile, mean and standard deviation, Pearson's correlation, Anova, Duncan's multiple range test and Heckman analysis First, Interchange amount of Benefits type household was significantly different according to the householder's gender, existence or nonexistence of a spouse, age, educational background, home ownership, family type and place of residence. However, interchange amount of provide- type households were significantly different according tohouseholder's gender, existence or nonexistence of a spouse, educational background, whether retired or not, and home ownership. Second, The receptive type of households and net receptive expense of households in terms of the financial resources interchanges and the findings of Heckman analyses suggest that the variables to have a significant effect on the receptive types of financial interchanges were as gender, age, education level, retired or not, and current economics. Factors having an effects on net receptive expense were age, and family type and for the number of receptive of financial resources, whether there is the receptive of financial resources, total income, total asset. Third, The supplying type of households and net supplying expense of households in terms of the financial resources interchanges, whether or not the type of financially supplying households is significant were residential area, total income, house ownership. Factor having an effect net supplying expense were age, family type, whether there is the supplying of financial resources, family satisfaction, and house ownership.

  • 데이터베이스와 관련된 표준화는 기본 참조모델 설정을 통하여 크게 데이터베이스 일반, 데이터, 데이터베이스의 세가지 분야로 나누어 설명할 수 있다. 이러한 데이터베이스 국제표준화 활동은 현재 다양하고 적극적으로 추진되고 있는 상황이다. 이에 국내의 표준화 활동을 강화하기 위해 문헌정보 분야의 ISO/TC46과 데이터베이스 분야의 ISO/IEC JTC1/SC32의 활동현황을 분석하고 이와 관련하여 국내 전문위원회의 활동을 강화하여 추진할 수 있는 방안을 제시하였다. 또한 관련된 국내 데이터베이스 표준 제정기관의 실태를 조사하고 향후 개선 방향을 제시하였다.

  • The insurance industry is highly competitive since it is difficult to differentiate one company's service from another. This paper examines how Ankuk Fire & Marine Insurance has differentiated its service and improved its competitive edge against others by using electronic data interchange (EDI). In order to improve its service level, Ankuk Fire Insurance has significantly reduced paper work by transmitting information electronically to its customers. This was possible with standardized product codes and databases which were installed both on the Ankuk and customer premises. Ankuk Fire Insurance transmits its customer's insurance information to the customer's database instead of hand-carrying or mailing it. The main benefits of this has been: (1) fewer errors as data does not need to be re-entered, (2) faster customer service with electronic data delivery, and (3) better quality customer service due to highly structured relationships with customers. EDI will soon be available to all insurance companies due to the goverment's aggressive promotion of a KTNet plan. Ankuk Insurance, therefore, needs to adopt the standardized protocol recommended by KTNet and develop new products which will give them a competitive edge and minimize the possibilities of losing their clients to other insurance firms.

  • The active use of the container vessel has brought with it high speed and reduced transit time ; however, the system of delivering the goods via B/L at the destination has lagged behind technical advances, becoming a burden to today's international traders, especially consignees and/or importers. More recently the sea waybill(SWB), that is to say an ocean-type AWB, has come on the scene. In Europe and the USA the use of SWB has increased significantly, but has also left room for improvement due to its short history of use. However, Recently, more attention is paid to SWB as a means to solve the B/L Crisis is getting more and more serious. In addition, due to its non-negotiability, the sea waybill could easily be replaced by messages sent between the interested parties by Electronic Data Interchange. With the paper document, transfer of title is fulfilled by transferring the original bill of lading to the buyer of the goods. However, in an electronic environment this is difficult to replicate. A number of solutions have been investigated, including using an electronic bill of lading, by controlling changes in title to goods through irrevocable, but transferable instructions to the carrier, or by appointing an independent electronic data registry, or replacing the bill of lading with a sea waybill, which is non-negotiable. The purpose of this study is to investigate some problems which may hinder SWB from coming into wide use and to analyse how to solve problems due to introduction of electronic sea waybill.

  • With expanded use of B2B(between enterprises), B2G(between enterprises and government) and EDI(Electronic Data Interchange), and increased amount of available network information and information protection threat, as it was judged that security can not be perfectly assured only with security technology such as electronic signature/authorization and access control, Bayesian networks have been developed for protection of information. Therefore, this study speculates Bayesian networks system, centering on ERP(Enterprise Resource Planning). The Bayesian networks system is one of the methods to resolve uncertainty in electronic data interchange and is applied to overcome uncertainty of abnormal invasion detection in ERP. Bayesian networks are applied to construct profiling for system call and network data, and simulate against abnormal invasion detection. The host-based abnormal invasion detection system in electronic trade analyses system call, applies Bayesian probability values, and constructs normal behavior profile to detect abnormal behaviors. This study assumes before and after of delivery behavior of the electronic document through Bayesian probability value and expresses before and after of the delivery behavior or events based on Bayesian networks. Therefore, profiling process using Bayesian networks can be applied for abnormal invasion detection based on host and network. In respect to transmission and reception of electronic documents, we need further studies on standards that classify abnormal invasion of various patterns in ERP and evaluate them by Bayesian probability values, and on classification of B2B invasion pattern genealogy to effectively detect deformed abnormal invasion patterns.
