In this paper, we investigate visual and quantitative analysis of different tastes in the liquids using multi-array chemical sensor (MACS) based on the ion-selective electrodes (ISEs), which is so called the electronic tongue (E-Tongue) system. We apply the Fuzzy C-means (FCM) algorithm combined with Principal Component Analysis (PCA), which can be used to reduce multi-dimensional data to two- or three-dimensional data, to classify visually data patterns detected by E-Tongue system. The proposed technique can be determined the cluster centers and membership grade of patterns through the unsupervised way. The membership grade of an unknown pattern, which does not shown previously, can be visually and analytically determined. Throughout the experimental trails, the E-tongue system combined with the proposed algorithms is demonstrated robust performance for visual and quantitative analysis for different tastes in the liquids.

Despite the rapid adoption of electronic journals, the need for print journals still remains. The current level of foreign journals acquisition poses a threat to strengthening the national research capabilities. Furthermore, there is too much overlap among academic libraries for foreign journals. We propose the establishment of government funded foreign research information centers to systematically acquire and distribute foreign print journals. We discuss specific approaches to selecting and operating such centers. Foreign research information centers are expected to enhance the national scholarly information infrastructure as well as the academic libraries' core capabilities.

A variety of pattern recognition algorithms including neural networks may be applicable to the identification of odors. In this paper, an identification technique for an electronic odor sensing system applicable to wound state monitoring is presented. The performance of the radial basis function(RBF) network is highly dependent on the choice of centers and widths in basis function. For the fine tuning of centers and widths, those parameters are initialized by an ill-conditioned genetic fuzzy c-means algorithm, and the distribution of input patterns in the very first stage, the stochastic gradient(SG), is adapted. The adaptive RBF network with singular value decomposition(SVD), which provides additional adaptation capabilities to the RBF network, is used to process data from array-based gas sensors for early detection of wound infection in burn patients. The primary results indicate that infected patients can be distinguished from uninfected patients.

Thesis is very valuable primary and secondary infomation resource in that it contains systematic research methods, comprehensive and detailed data, and creative research results in specific areas. But thesis has been neglected in many libraries and information centers due to the problems of accessibility and obtainabiliy problems as one of a Grey Literature. As information technology and networks have been developing rapidly, the digitalization of thesis full-text and the possibility of online access arc also increasing. In this study, value and the characteristics of thesis is firstly reviewed. Secondly, by analyzing the current digitalization state of some domestic and foreign universities and institutions, some principles for the effective electronic transmission and effective management of thesis are suggested as one of knowledge management. Furthermore useful information is suggested for the users in terms of the online access and obtainability.

If the service provider provides mobile service with mobile switching centers that use different handoff message format, the soft-handoff between mobile switching centers is not available and the hard-handoff scheme is used instead. When this occurs, calls are often disconnected or there is an interruption of service. This can be very annoying to a mobile user. We propose the handoff subsystem of the ATM switch which provides the soft-handoff between wireless cells under the control of different MSCs. The proposed handoff subsystem transforms the handoff message format of the source MSC to that of the destination MSC. It also provides efficient routing scheme that distributes handoff packets to balance the traffic load.

This study aims to analyze the current policies and problems associated with the electronic records disclosure and to suggest the access paradigm for electronic records management. For this, Act on Disclosure of Information by Public Agencies. Public Records Management Act, and Electronic Government Act are analyzed in the light of public access to electronic records. The analysis lays special emphasis on the scope of public records to be disclosed, time to disclosure of public records. computer editing for pubic service. records dissemination through Internet, and the role of records centers and public libraries. Based upon the analysis, policy directions for electronic records management are suggested.

This study aims to propose a lifecycle cost model for electronic records & archival management. For this purpose, the study identified cost elements based on analysing public records & archival management activities and proposed cost factors for management by applying data gathered from records centers & archives. The study employed various methods: desk research, activity analysis, a cost information survey and interviews with experts in digital preservation, and records/archival management. The study made the first step to the cost studies in electronic records management in Korea. It is expected to update the CoMMPER model and redefine activities of electronic records management. Further case studies based on the model is required.

Clustering is one of the most well-known unsupervised learning methods that clusters data into homogeneous groups. Clustering has been used in various applications and FCM is one of the representative methods. In Fuzzy C-Means(FCM), however, cluster centers tend leaning to high density areas because the Euclidean distance measure forces high density clusters to make more contribution to clustering result. Previously proposed was density-independent clustering method, where cluster centers were made not to be close each other and relived the center deviation problem. Density-independent clustering method has a limitation that it is difficult to specify the position of the cluster centers. In this paper, an enhanced density-independent clustering method with an additional term that makes cluster centers to be placed around dense region is proposed. The proposed method converges more to real centers compared to FCM and density-independent clustering, which can be verified with experimental results.

Recently the government civil affairs administration system has been advanced to a cloud computing environment from a simple network environment. The electronic civil affairs processing environment in recent years means cloud computing environment based bid data services. Therefore, there exist lots of problems in processing big data for the government civil affairs service compared to the conventional information acquisition environment. That is, it processes new information through collecting required information from different information systems much further than the information service in conventional network environments. According to such an environment, applications of providing administration information for processing the big data have been becoming a major target of illegal attackers. The objectives of this study are to prevent illegal uses of the electronic civil affairs service based on IPs nationally located in civil affairs centers and to protect leaks of the important data retained in these centers. For achieving it, the safety, usability, and security of services are to be ensured by using different authentication processes and encryption methods based on these processes.
