Most of existing expert systems developed for Web use CGI-based techniques and this frequently makes them suffer from the overburden of commercial Web servers, which deal with large-scale services. However, since HTML-based inference technique represents expert's knowledge by hyperlinks among HTML documents, the hypertext function of the Web can perform the inference efficiently in terms of time and space without the help of additional inference engines. In spite of such benefits, when the expert's knowledge is relatively large and/or complicated, the HTML-based inference technique has usually become to have a hard time of dealing with a lot of HTML documents because generation and management tasks of the numerous HTML documents would cause big trouble to the knowledge engineer. To resolve this problem, we developed an automatic generation and management tool for Web-based inference sites, called WeBIS. With this tool, a knowledge engineer can input and edit expert's knowledge using Expert's Diagram on the GUI(Graphical User Interface) environment and automatically generate hyper-linked HTML documents for Web-based inference from the Expert's Diagram.

Response surface methodology (RSM) is a group of statistical modeling and optimization methods to improve the quality of design systematically in the quality engineering field. Its final goal is to identify the optimal setting of input variables optimizing a response. RSM is a kind of knowledge management tool since it studies a manufacturing or service process and extracts an important knowledge about it. In a real problem of RSM, it is a quite frequent situation that considers multiple responses simultaneously. To date, many approaches are proposed for solving (i.e., optimizing) a multi-response problem: process capability function approach, desirability function approach, loss function approach, and so on. The process capability function approach first estimates the mean and standard deviation models of each response. Then, it derives an individual process capability function for each response. The overall process capability function is obtained by aggregating the individual process capability function. The optimal setting is given by maximizing the overall process capability function. The existing process capability function methods usually use the arithmetic mean or geometric mean as an aggregation operator. However, these operators do not guarantee the Pareto optimality of their solution. Moreover, they may bring out an unacceptable result in terms of individual process capability function values. In this paper, we propose a maximin-based process capability function method which uses a maximin criterion as an aggregation operator. The proposed method is illustrated through a well-known multiresponse problem.

This study evaluated the effectiveness of a visiting inspection and knowledge-based food safety education program for cooks in child care facilities provided by the Center for Children's Foodservice Management (CCFSM). The research was conducted among cooks at 91 child care facilities; 56 existing facilities had been enrolled since 2011 and provided with the inspection and education program for 2 years and 35 new facilities were enrolled in 2012 and provided with the program for 1 year. The food safety knowledge of the cooks of the two groups were compared by the presence and duration of inspection and education programs provided by the CCFSM. The total mean score for food safety knowledge was $18.48{\pm}3.09$, with a group score of $19.34{\pm}2.68$ for the existing facilities and $17.11{\pm}3.25$ for the new facilities (P<0.001). There was no significant difference between groups in the knowledge of the personal sanitation. According to a post-test for food safety knowledge in the two groups after the completion of a one-year program on food safety by CCFSM, the mean score of food safety knowledge increased by 2.92 to 20.03 for cooks of the new facilities and both groups had significantly higher mean scores than pre-test (P<0.001). There was no significant difference in the mean score of each group by post-test. Thus, the one-year continuous program by CCFSM was effective in improving food safety knowledge of the cooks of the child care facilities.

Process-based knowledge management is `have knowledge operation system based in the task process and provide the accumulated knowledge of an organization for its members performing their task through a system in an appropriate format.' If it is embodied in the organization it is expected to significantly enhance the task process and knowledge. Meanwhile, Maier and Remus realized that if the organization`s strategy is added to the existing objective of knowledge management promotion strategy, it is in accord with major objectives of the process management such as BPR or BPM. Based on this, Maier and Remus devised a framework for promotion strategy of process-based knowledge management. As a result of analyzing their framework by applying it to examples of knowledge management promotion of the Ministry of Labor, it was found that process-based knowledge management should be applied in order to solve the problems and reflect improvement suggestions which had been constantly pointed out. Furthermore, the direction to be applied in connection with the improvement suggestions was presented in this study.

Construction companies recently have been highly interested in developing information system as following the advanced of IT technology. Especially, with advent of knowledge-based paradigm, Knowledge Management System(KMS) has been actively built. However, current KMS is not optimized and not satisfied because KMS is not integrated with existing information system and has problems of method of knowledge management. The objectives of this research is to develop integrated KMS, which synthesizes knowledge and functions of scattered information system. This research investigates current KMS and analyzes the requirements of KMS. Based on the requirements, the utilization of construction portal is suggested. And integrated knowledge management method, which has connections with applications in construction portal, is suggested and the system is developed.

The development of web-aware knowledge discovery system has received a great deal of attention in recent years. It plays a key-enabling role for competitive businesses in the E-commerce era. One of the challenges in developing web-aware knowledge discovery systems is to integrate and coordinate and coordinate existing standalone or legacy knowledge discovery applications in a seamless manner, so that cost-effective systems can be developed without the need of costly proprietary products. In this paper, we present an approach for developing a framework of web-aware interoperable knowledge discovery system to achieve this purpose. This approach applies RMI and high-level code wrapper of Java distributed object computing to address the issues of interoperability in heterogeneous environments, which includes programming language, platform, and visual object model. The effectiveness of the proposed framework is demonstrated through the integration and extension of the two well-known standalone knowledge discovery tools, SOM_PAK and Nenet. It confirms that a variety of interoperable knowledge discovery systems can be constructed efficiently on the basis of the framework to meet various requirements of knowledge discovery tasks.

This paper developed measurement indices for intellectual capital of public R&D organizations and investigated causal relationships among the components. We developed 10 measurement factors and 37 indicators and confirmed the reliability of these measurements. We offered an alternative to the existing model for searching causal relationships. From our survey research, using the structural equation model, we found a new relationship. In contrast to the existing model, we found a cycling relationship among three variables: human capital causes structural capital, structural capital causes relational capital, and relational capital causes human capital.

In manufacturing process, usually 2-dimensional part drawing is used as a basic data. If a designer wants to recognize 2-dimensional drawing and formulate 3-dimensional shape, a proper feature recognition rule is required as a prerequisite step. These rules are converted Into knowledge base, should be ed separately in the recognition program and can be referenced In similar way of database application. In this paper, basic feature recognition rules are addressed in structure type knowledge base, and the application system is formulated which can be operated separately with existing data driven program.

The importance of Knowledge Management (KM) can be easily recognized in many diverse aspects of the theory studies and in KM's efforts to help implement the government's policy to innovate corporation management. The core of KM is to improve the circulation of knowledge by generation, accumulation, sharing, utilization and acquisition by learning. The improvement of knowledge circulation would result in high quality and quantity of intellectual assets in corporations and make decision-making more efficient. This, too, is the operational philosophy of the special libraries. The primary objective of this study is to promote KM by presenting KM methodology and by explaining a theoretical background and cases, based on the existing special libraries. I cite an example of a case wherein merging intellectual assets and human resources activated the company culture. The reference service system, which is the core of the special library, was used in this merging.

Uncertainty means incomplete stages of knowledge of propositions due to the lack of consensus of information and existing knowledge. As the amount of academic literature increases exponentially over time, new knowledge is discovered as research develops. Although the flow of time may be an important factor to identify patterns of uncertainty in scientific knowledge, existing studies have only identified the nature of uncertainty based on the frequency in a particular discipline, and they did not take into consideration of the flow of time. Therefore, in this study, we identify and analyze the uncertainty words that indicate uncertainty in the scientific literature and investigate the stream of knowledge. We examine the pattern of biomedical knowledge such as representative entity pairs, predicate types, and entities over time. We also perform the significance testing using linear regression analysis. Seven pairs out of 17 entity pairs show the significant decrease pattern statistically and all 10 representative predicates decrease significantly over time. We analyze the relative importance of representative entities by year and identify entities that display a significant rising and falling pattern.
