기업데이터네트워크를 좀 더 세분화해보면 Wide Area Network와 Local Area Network로 분류 할 수 있다. WAN은 기업의 본사, 전산센타 그리고 지점들간의 통신을 위하여 필요한 네트워크를 말하며, LAN은 본사, 전산센타, 지점내의 전산 자원들을 네트워크로 구성하는 것을 말한다.

Wireless Sensor Networks are consisted of sensor nodes that communicated with each other to transmit information. Because sensor nodes have physically many limits, wireless sensor networks are hard to adopt for traditional networks. Transmissions are consumed most energy of sensor nodes. That's why energy-efficient transmission techniques and QoS support techniques for different kind of data are most important in wireless sensor networks. The thesis proposes the agent based framework for energy distribution and QoS in wireless sensor networks. Agents have its own behavior policy by means of a gene, which is optimized by genetic operations. Agents behavior to distribute energy consumption over sensor nodes. Simulation results show that the enhanced framework extends the lifetime of sensor nodes. Successful transmission ratios of emergency data and non emergency data are increased by 27% and 14%, respectively. Also, the results demonstrate that Qos of networks are improved.

We analyzed romance of the three kingdoms written by Luo Guanzhong by using complex network to compare its properties with those of social network. The three kingdom network has a scale free and hierarchical network properties. Human-human interaction networks are dramatically changing in response to time and space. Due to lack of the dynamic interacting data, the researches only focus to analysis for properties of the statical networks. The romance of the three kingdoms is a Chinese historical novel based upon events from the end of the Han Dynasty, the Three Kingdoms era of China, and the reunification of the land. There are over a thousand characters, over a three thousand human-human interactions, and the dynamic changed in human-human interactions in the historical novel. Here, we introduce that a possible method for analyzing about dynamic changing of the complex network.

Ad-hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration or reliable support services such as wired network and base stations. Recently, Ad-hoc networks are evolving to support multimedia contents according to expansion of ad hoc multi-hop communication system. Wireless ad-hoc network is different from the conventional wired network by frequent changes in network topology, number of routers and resources, there are a number of problems in applying conventional routing protocol to ad-hoc network. The AODV routing protocol is proposed for mobile node in ad-hoc networks. AODV protocol that provides to guarantee QoS for data transmission in ad hoc networks that link break frequently occurs. In this paper, AODV routing protocol based NDIS(Network Driver Interface Specification) is implemented. We design high performance image transmission that can operate with software(AODV) for ad-hoc networks without degradation. and verify operation of AODV routing protocol on the test bed.

Smartwork technology, using teleworking, smartwork centers and mobile terminal, provides a flexible work environments without constraints of time and space. Smartwork system to increase the work efficiency has the information protection threats according to their convenience. Thus, in order to build smartwork, it is proper to provide information protection audit to help ensure the information protection. In this paper, we have proposed an infortaion protection audit model at the practical and technical level for building a smartwork environment. We were classified as a terminal, network and server area for information protection, and derived a professional information protection check items. Further, by establishing a smartwork information protection audit time to map ISMS control items, we have proposed an audit model so that it is possible to improve the security and efficiency. It also verified whether the proposed model is suitable or not by doing a survey if deduced audit domain and check items correspond with the purpose of the smartwork information protection audit to auditors and IT specialists. As the result, this study was 97% satisfaction out of 13 check items.

For workflow systems using XML documents for saving workflow process definition and especially for XML-based worflow systems, a repository needed to provide control for XML documents. The repository allows uniform access to shared data and facilitates integration among tools in workfolw systems. An XML repository gives the best solution to maintain, exchane, and modify the workflow process definition meta data, which is in the form of XML documents . The XML repository, where users can lookup the worflow definition objects, serves as the metadata foundation of the workflow system. In this paper, we developed for XML Repository(called REPOWO : REPOsitory for Workflow) that can store, delete, search and transform XML documents. REPOWO is implemented by combining EJB components based on RDBMS. By REPOWO, workfolw process definitions, data type definitions and transition informations can be easily manage.

The purpose of this study is to provide the fruitful directions for the future studies on smart work by analyzing the past and present trends that are related to smart work. For this, a wide range of materials and MA and PhD treatises produced from 1992 to the present have been collected and have been analyzed on the basis of various standards, including objective of study, approach method, methodology, method of data collection, statistical technique of analysis, summary of problems and alternativesto overcome limitations. Lessons and implications of this study for the possibility of smart work are presented. I hope this study will contributeto future studies concerned about smart work.
