1990년대 웹 개념의 등장으로 인터넷을 개방형 네트？, 사용자 친근성 및 편의성이라는 특성을 바탕으로 급속히 일반화되면서 각종 정보를 제공하는 정보 시스템에서도 커다란 변화를 가져왔다. 웹은 텍스트 정보뿐만 아니라 이미지, 오디오, 비디오 등 멀티미디어 정보를 쉽게 제공함으로써 기존 정보 시스템의 웹 기반으로의 전환을 가속화시키게 되었다. 물론 정보 내용도 텍스트 위주의 단순 초록 정보에서 전문(Full-Text) 정보로 급속히 이전되기 시작하였으며, 전문 정보를 처리하는 다양한 문서 포맷들로 등장하기 시작하였다. 하지만, 전문 정보는 본질적으로 대용량의 시스템 메모리, 막대한 처리시간, 보다 많은 전송용량 등을 요구하게 되므로 웹 기반 전문 시스템의 구축시 이러한 요인들을 세밀하게 비교 평가하여야 한다. 따라서 본 연구는 웹 기반 정보 시스템에서 어떻게 전문을 처리할 것인가에 초점을 맞추어 문서의 통합 정보 기능을 제공하는 정보시스템을 설계 구현한다. 먼저 인터넷상에서 표준 문서형식으로 사용중이거나 개발중인 문서 포맷들의 특징을 검토하고, 정보 시스템의 관점에서 전문정보를 어떤 문서 포맷으로 처리하는 것이 적합한가를 실험하고 평가한다. 그리고 이를 기반으로 본 연구의 목적인 전문 정보를 PDF 문서로 제공하는 웹 기반 정보 시스템을 설계 구현한다.

In Bayesian multi-target tracking, the Poisson multi-Bernoulli mixture (PMBM) filter is a state-of-the-art filter based on the methodology of random finite set which is a conjugate prior composed of Poisson point process (PPP) and multi-Bernoulli mixture (MBM). In order to improve the random finite set-based filter utilized in multi-target tracking of sensor scanning, this paper introduces the Poisson multi-Bernoulli mixture filter into time-matching Bayesian filtering framework and derive a tractable and principled method, namely: the time-matching Poisson multi-Bernoulli mixture (TM-PMBM) filter. We also provide the Gaussian mixture implementation of the TM-PMBM filter for linear-Gaussian dynamic and measurement models. Subsequently, we compare the performance of the TM-PMBM filter with other RFS filters based on time-matching method with different birth models under directional continuous scanning and out-of-order discontinuous scanning. The results of simulation demonstrate that the proposed filter not only can effectively reduce the influence of sampling time diversity, but also improve the estimated accuracy of target state along with cardinality.

Data mining is the process of autonomously extracting useful information or knowledge from large data stores or sets. For analyzing data of manufacturing processes obtained from database using data mining, source data should be collected form production process and transformed to appropriate form. To extract those data from database, a computer program should be made for each database. This paper presents a program to extract easily data form database in industry. The advantage of this program is that user can extract data from all types of database and database table and interface with Teamcenter Manufacturing.

For effective management and processing for civil affairs, online public services are in operation in every administrative organizations. However, due to the lack of links in each government departmental business processes on e-Government system, the satisfaction of the civil petitioners has not improved. In this paper, we propose an improved business process for the implementation of one-stop integrated civil affairs and suggestions services on e-Government system to reduce the time and cost for processing civil affairs and to improve the efficiency of the public services by cutting down the cost and time. This paper also suggests the ways to improve the quality of public service through redesigning civil affairs processing in the light of integrated system for the civil affairs and its suggestion.

In this paper, a reliable control system structured with dual CPU modules and dual I/O modules is implemented as a means of achieving a highly reliable fault tolerant control system. For this, faults in the system modules are first examined, and a fault detection technique consisting of self diagnostic, comparison process, and exception processing is applied. Self diagnostic is used to locate which components in the modules have been failed, while comparison process is to cmpare control outputs computed by both CPU modules and protect the plant from malfunction by blocking failed control outputsin advance. Finally exception processing is used to determine the faults that are not detected immediately by the self diagnostic and comparison process, e.g. bus error processing when acknowledge signal for data transfer is not activeted in the I/O modules. Also reliability analysis is conducted for the discrete time Markov model with dual structure. It is shown quantitatively that the reliability is improved in the control system with dual structure in comparison with a system with single module structure.

Consumer knowledge has been discussed as an important concept to understand information processing such as information search and evaluation process. It has been defined as the amounts and contents of information in consumer's memory accumulated by experiences. According to literature review, experts who have much knowledge are likely to retrieve their information related to products for a purchase efficiency. Therefore, they are likely to simplify the information processing for a choice. The purpose of this study was to examine the relationship between clothing product knowledge and evaluative criteria for a purchase. The results were as follows; First, it was found out that evaluative criteria were composed of four dimensions such as the management, the esthetic, the fitness and the brand. Therefore, it is implied that evaluative criteria for purchasing clothing products were multidimensional. Second, the level of objective knowledge was low, and consumers perceived that they didn't have much knowledge related with clothing products. Also, the relationships between objective and subjective knowledge were positive but low. Third, the evaluative criteria were effected by the level of consumer's knowledge significantly. In subjective knowledge, the subjects in a high group considered all criteria more deeply than in a low group. But there was a significant difference only in the esthetic between two groups in objective knowledge. The results of this study imply that consumer knowledge may influence evaluation process. Knowledgeable consumer would consider product attributes deeply for evaluating clothing products, and especially, the esthetic would be an important factor as an attribute including the instrumental and expressive functions in a purchase phase. Therefore, consumer knowl- edge would be a basis of predicting expert's information processing and managing heavy buyer or loyal consumers in apparel industry.
