ROK Forces operate Link-11, Link-16 and Korean Tactical Data Link System with Link-K(JTDLS: Joint Tactical Data Link System). As the change from Link-11 to Link-22 approaches, in the JTDLS Completed Business will be added tactical data link processing such as Link-22. In this paper, we propose the data management structure for data from multiple tactical data links. Also, we simulate to find ways to process a lot of data quickly using Shared Memory, In-Memory DB, Self Development DB in DLP, and then we confirm the result.

The compensation characteristics of the distorted WDM channels compensated for by dispersion management (DM) and optical phase conjugation in the long-haul ($50\;fiber\;spans{\times}80km$) transmission link with the randomly distributed single mode fiber (SMF) length and residual dispersion per spans (RDPS) for implementing of the flexible link configuration are investigated. It is confirmed that the compensation effect in the link with the randomly distributed SMF length and RDPS is similar with that in the link with the uniform distribution, when the launch power of WDM channels are restricted within 0 dBm. This result means that the proposed link configuration is useful for designing and deploying the long-haul WDM transmission link.

The management of enterprise knowledge has been increasingly important because knowledge emerges as the new basis of competition in postcapitalist society. One of the key issues in knowledge management is to put knowledge into a repository where it can be easily stored, reused, and recreated. This paper proposes a model repository and the corresponding knowledge management framework. The emphases of model repository is on abstraction knowledge in the form of schematic models. Two major benefits are model independence and model integration. A metaschema is constructed according to six conceptual components: separate unit, external link, internal link, separate unite descriptor, link descriptor, and composite descriptor, which can be applied for a variety of models. A prototype system with a case illustrates the practical usefulness of model repository for knowledge management

Purpose: The Malaysia Education Blueprint is primarily concerned with the transformation of students' minds through the curriculum offered at the school level (2013-2025). Diversity in the application of teaching and learning methods is one means of achieving the transformation of students' minds through the Secondary School Standard Curriculum. Consequently, the production of ExSheetLink's Module for Accounting Education is the primary outcome of this study, which had three objectives: the need for ExSheetLink's Module in the process of producing financial statements for Accounting Students in secondary school to the Accounting Teacher; and the design of ExSheetLink's Module that meets the entire process in the production of financial statements for Accounting Students in secondary school based on the Documents Curriculum and the Accounting Students' needs. Research design, data and methodology: This study outlines the research framework for module development in accordance with the Design and Development Research Method, which combines multiple research techniques (Mixed Method). Results: The development of ExSheetLink's Module is completed and can be used for the level of effectiveness purposes. Conclusion: The transformation of Accounting Students' minds is a success thanks to the ExSheetLink Module. Researchers also suggested that all Malaysian Secondary School accounting students test the ExSheetLink Module.

New optical transmission link techniques improving performance of WDM channels, each channel have bit rate of 40 Gbps, are proposed. The proposed optical link configuration consist of optical phase conjugator (OPC) placed at middle of total transmission length, and dispersion management (DM) as a role of compensating dispersion cumulated in transmission line. It is confirmed that Q-factor of total channels are improved by combining OPC and DM in optical transmission link as a result of following fact; DM not only mitigate the cumulated dispersion in total transmission line but also help OPC to compensate optical nonlinearities. And, it is confirmed that the improvement of Q-factor of overall WDM channels depends on net residual dispersion (NRD) of optical link.

The combat systems in Korea navy have been operating some kinds of tactical data link systems such as Link-11, ISDL and JTDLS. Each tactical data link system has the ability to transmit and receive tactical information like track, engagement, weapon information by using unique message of theirs. And each unique message has their own format. But a number of tactical data link system make combat effectiveness worse because their major functions are duplicated unnecessarily. So, many advanced countries are trying to make united data link system. Similarly, the combat systems in Korea navy will operate C4I data link system, and it is combined version current ISDL, KNCCS and JTDLS data link system. In this paper, we consider the development current tactical data link systems in Korea navy. Also, compare the characteristics between I-message used in ISDL and Host-Interface message used in C4I. From these results, we analyze advanced points about C4I data link system.

본 연구에서는 하이퍼텍스트나 웹 문서의 검색에서 링크로 연결된 문서들이 주제적으로 서로 관련되어 있다는 것을 기반으로 하여 링크정보를 참조한 웹 문서 클러스터링 기법을 제안하였고 이것을 이용하여 검색된 결과를 질의 근접 순위화함으로써 웹 문서 검색의 성능을 향상시키는 방안을 연구하였다. 본 연구에서 사용된 웹 문서 집단은 웹(WWW)을 통하여 직접 수집하였으며 웹 문서가 다른 웹 문서를 링크하고 있을 때를 OutLink, 다른 웹 문서로부터 링크를 받고 있을 때를 InLink로 구분하였다. 실험결과 OutLink를 참조하여 클러스터링을 수행하는 기법과 InLink를 참조하여 클러스터링을 수행하는 기법 모두 검색 성능을 향상시켰다.

This study describes the concept of link resolvers using OpenURL. Then, the study analyzed the commercially available link resolvers in terms of remote & local hosting, title list, customization of the services and usage statistics. The results will help the libraries select the appropriate link resolvers that are relevant to the features of the libraries.

As the number of Mobile IP users is expected to grow, the signaling overhead associated with mobility management in the wireless Internet is bound to grow. And since the wireless link has far less bandwidth resources and limited scalability compared to the wired network link, the signaling overhead associated with mobility management has a severe effect on the wireless link. In this paper, we propose IP-Grouping algorithm that can greatly reduce the signaling cost in the wireless link as Access Routers(ARs) with a large rate of handoff are grouped into a Group Zone. Based on the numerical analysis and simulation, we show that the wireless signaling cost in the IP-Grouping is much lower than that of the Hierarchical Mobile IPv6 under various condition.
