This paper is concerned with a conceptual design of a knowledge-based modeler for network analysis. The "knowledge-based modeler" approach is suggested as a method for incorporating the user's qualitative knowledge and subjective decison in the course of the mathematical modeling and the subsequent solution procedure. The submodules of the proposed modeler such as database, model/algorithm base and functional knowledge bases are identified and the flows of information between the submodules are sequentially defined. A prototype system is implemented for experimental purpose by using the application software GURU.ware GURU.

본 연구의 목적은 대학 글쓰기 수업에서 내용지식으로부터 학생의 통합지식을 구성함에 있어 지식통합의 단위와 기준을 세분화하여 제시하는 것이다. 이를 위하여 전형성 있는 대학 글쓰기 교재 세 권을 분석하고 내용지식의 구성에 대한 제시방법을 텍스트 질적 분석방법을 통해 살폈다. 분석 절차와 제시방법은 Creswell의 질적 연구에서의 나선형 분석 모델을 따랐다. 이는 자료 수집부터 분석, 제시까지 순환적으로 반복되는 자료 분석 방법이다. 이를 통해 내용지식 구성단위에는 글 전체 단위, 단락 단위, 문장 단위의 세 가지 차원이 있음을 발견하였다. 또한 내용지식 구성의 체계화된 교육을 위해서 이 세 가지 단위 차원을 모두 다루는 것이 바람직함을 제시하였다. 다음으로 지식통합의 과정별 기준과 교육내용을 제안하였다. 지식의 선별 과정에서는 논지와의 적합성과 보충성의 기준을, 지식의 조직과 통합과정에서는 통일적 통합, 모순적 통합, 배경적 통합, 종합적 통합 등의 기준과 내용을, 지식의 표현과 인용 과정에서는 정확한 표현과 표기법, 출처표시 등의 절차 지식을 제안하였다. 나아가 표현의 차원에서 일반 글쓰기 교재에서 빈번하게 연습되는 '바꿔 말하기' 과정도 '요약, 연계, 해석과 변용'이라는 세 가지 차원에서 연습될 필요가 있음을 제안하였다. 그러나 이러한 결과는 몇 차례 더 세분화의 과정을 거쳐야 대학 수준의 글쓰기 교재에 활용하기 적합하고 체계화된 지식통합의 요목들을 정련할 수 있을 것으로 보이며 이를 추후 연구의 과제로 남긴다.

Purpose: Purpose of the study was to identify the effect of the Comprehensive Education Program (CEP) on intra-procedure anxiety, post-procedure uncertainty and athletic performance of back strengthening of patients undergo spinal nerve block (SNB). Methods: The participants (experimental group=33, control group=33) were recruited from a university hospital in G metropolitan city. Data were collected from July to November 2015. The experimental group was individually provided with a booklet/motion picture about the SNB and back strengthening exercise training before the SNB. This group also received a leaflet about back strengthening exercise post SNB. The Anxiety-Visual Analog Scale (A-VAS), the Mishel adapted uncertainty scale and newly created knowledge scale/athletic performance checklist were utilized as our study tools. Results: Intra-procedure anxiety score (F=25.70, p<.001), post-procedure uncertainty score (F=82.56, p<.001), post-procedure knowledge score (F=14.63, p<.001) and athletic performance rate of back strengthening (p=.003) of the experimental group showed statistically significant differences in comparison with the control group. Conclusion: This CEP is a cost and time-effective intervention for patients who undergo spinal injections, so it should be actively utilized as an educational management strategy in outpatient.

Virtual project organization may be recognized as one of the promising business models in which many knowledge sources externalize through cross boundaries of knowledge-based organizations. This paper proposes a knowledge competence evaluation of virtual project organization based on the following perspectives: 1) Individual knowledge perspective, 2) Activity-oriented knowledge perspective, and 3) Knowledge-driven social network perspective. In the framework, individual knowledge competence having experienced or learned from knowledge-based activities and virtual networks in the project, should be evaluated according to the assumption that knowledge and collaboration competence depends on the activities and networks acquired proportionally by the past participation to projects. An illustrative SI example is given in order to validate the proposed evaluation and computing procedure.

Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.

Seat belt is an important means to protect drivers and passengers from the damages by car accidents. Many ways to increase the seat belt wearing rate have been proposed through human factors researches. The primary ways to increase seat belt use rate have emphasized the intention-behavior cycle. This study focused on the gap between intention and behavior. The gap may be bridged by the habit for seat belt use behavior. Divers following a desirable car starting sequence, from sitting on the chair, fastening seat belt, starting engine to moving a car, reported that higher belt wearing rate and unconscious behavior (automated response). That is, the habitualized procedure knowledge prevented drivers from forgetting to fasten their seat belt. The reminder systems such as warning light and warning sound could not significantly give an influence in remembering to fasten seat belt. In order to increase the seat belt use rate, the desirable car starting procedure should be included in the driving education program.

While Logic Based Expert System (LBES) has a merit of rapid and complete inference, it also has a defect of huge knowledge base. Hierarchical LBES (HLBES) replaces the assertion time inference of LBES with the multi-level logic minimization procedure, and it guarantees smaller knowledge base comparing with LBES. This paper has two contributions. The one is proposing so-called fact-minimization procedure which reduces not only the number of facts or measured events but also the size of knowledge base dramatically. The other contribution is application of HLBES and the proposed fact-minimization to the fault diagnosis of power system. The application is successfully performed in the example with the transmission system which takes 72 goals and 352 facts.

Many dispatching rules have been developed for the on-line control of product flow in a job shop. The introduction of a flexible manufacturing system (FMS) has added a new requirement to classical job shop control problem : the selection of machines by parts of different types. An FMS can keep a great deal of information on the status of the system, such as information on what is scheduled in the near future, with great accuracy. For example, the knowledge of the time when the next part will arrive at each machine can be neneficial for the routing. This paper tests the effects of the use of this knowledge for part routing on the parts flow time (sum of the time for waiting and service) under a simple routing procedure- a look-ahead routing procedure. A test under many operating conditions shows that the reduction of part flow time from the cases without using this information is between 1% and 11%, which justifies more study on this routing procedure at real production sites when machine capacity is a critical issue. The test results of this paper are also valid for other highly automated systems such as the semi-conductor fabrication plants for routing when the arrivals of parts in the near future are known.

This paper presents a procedure for automated extraction of ridge shadows in noisy gray images. This procedure mainly consists of 1) a deformable model which is designed basing upon the knowledge about the shape of shadows and is expected to be useful in extracting ridge shadows especially located in low signal to noise ratio background, and 2) the scale space scheme which is also useful even if there is less information about the size and the positions of ridge shadows in advance. This procedure is applied to artificial images and its performance is evaluated experimentally.

With the rapid changes of business environments and the tremendous amount of information generated from those environments, most companies must learn to manage those changes and information more effectively. Furthermore, within those amounts of information, the information that meets with achieving the goal of each company should be selected and managed as a core competency, i.e. the knowledge, visible and invisible assets of the company. Knowledge management, as a tool of creating, sharing, and applying such knowledge, has pursued those requirements of companies and been studied by many researchers and consultants, especially focusing on the Knowledge Map'. It is said that a knowledge map is a powerful tool for scanning and managing the knowledge that exists in a company and that it is the most important part of establishing a knowledge management base. Until now, however, there have been no specific or practical models for establishing a knowledge map, in spite of the concern. For this reason, this paper suggests a practical model for establishing a knowledge map in terms of a knowledge acquisition procedure based on the traditional research concerning concept maps. In addition to this, for examining the validity of the model, a case study on the 'P' steel and iron company has been performed. This paper's methodology on developing a knowledge map and the procedures to apply them to the real business environment will suggest a cornerstone in the field of practical implementation of knowledge management.
