Objective : Patients complaining of dizziness and olfactory hallucination who were diagnosed and treated with the Shanghanlun disease pattern identification diagnostic system were analyzed to report cases. Methods : This is a case report on a patient who has been suffering from Dizziness andolfactory hallucination. According to Diagnostic system based on Shanghanlun provisions, Gyeji-tang was provided. The severity of Dizziness was evaluated by NRS. Results : When analyzing the patient's history and symptoms, it can be found in article No. 42 in Shanghanlun. In the first case, NRS changed from 8 to 2. In the second case, NRS change 8 to 1. Conclusions : Gyeji-tang can be effective in dizziness and olfactory hallucination with the Shanghanlun disease pattern identification diagnostic system.

상황 인식은 유비쿼터스 컴퓨팅 환경에서 중요한 핵심 기술 중 하나이다. 본 연구에서는 상황 인식 기술을 사례기반 음악추천시스템에 접목시켰다. 본 연구에서 제안하는 시스템은 음악청취의향 인식모듈과 음악추천 모듈로 구성된다. 음악청취의향 인식모듈은 사용자가 음악을 듣고 싶어 하는지 아닌지를 외부상황정보를 이용하여 추론한다. 사용자가 음악을 청취할 의향이 있다고 판단되면, 음악추천 모듈은 사용자와 유사한 성향을 보이는 다른 사용자들이 유사한 상황에서 주로 들었던 노래들을 사용자에게 추천한다. 제안 시스템과 전통적인 방식의 사례기반 음악추천시스템의 성능을 비교한 결과, 제안 시스템이 추천의 정확도에서 약 9% 포인트 높게 나타났다.

The shipbuilding industry is one of the domains which need an effective computer application. Particularly the productivity of process planning of a shipbuilding for crude -oil tanker can be greatly enhanced by introducing CAPP(Computer Aied Process Planning). In this paper we describe a prototype expert system which enables block division process planning in shipbuilding. The system determines block division lines of the midship sections of oiltanker. Case-based reasoning(CBR) approach is applied for this purpose instead of rule-based one.

It is very important to select the best employees who are suitable for their jobs and duties as considering the efficiency and productivity of the firms' performance. As a result, many kinds of selection methodologies and systems have been developed. Among them is the selection system based on the core competencies which is known as the superior selection systems that can increase the predictive validity who is the right people, compared to the traditional selection system based on the job analysis. Hence, the former has been focused in the complex business situation in recent years. In this case study, we examine the selection system case based on the core competencies of OSS team in Company A, which is one of the largest telecommunication firms and we suggest the implications. According to the results of this case study, defining the core competencies of the job and selecting the right people who had the related competencies not only decreased the turnover rate of OSS team in Company A, but also increased the employees' loyalty and satisfaction for the organizations. This study will be a benchmark to other departments that don't use competency selection system of Company A as well as the firms that want to adapt the selection system based on the core competencies. Also, this case study has a contribution that shows us an alternative model how can the firms identify and select the best right employees.

Objectives : The purpose of this case report is to report the effect of Daesiho-tang on adult acne by Shanghanlun provisions with extrusion therapy. Methods : According to diagnostic system based on Shanghanlun provisions, the patient was diagnosed with Taeyang-byung Gyeolhyung and treated by Daesiho-tang with extrusion therapy. The result of administrations were evaluated by Korean Acne Grading System(KAGS), Korean Skindex-29, and change of clinical symptoms. Results : After administration of Daesiho-tang for 150 days with weelky extrusion therapy, KAGS improved from grade 4 to grade 1, Skindex-29 improved from 67.93 to 15.51, and patient was very satisfied with the treatment. No serius treatment-related adverse events were reported. Limitations : This case is only one case that the level of evidence is weak. Two interventions were used together and the duration of photo was uneven. Conclusions : The patient almost recovered from acne treated by Daesiho-tang according to diagnostic system based on Shanghanlun provisions with extrusion therapy. This is the first case report that suggests '熱結在裏' on the number 136 provision of Shanghanlun means fever that is always present in chronic skin lesions.

This paper describes a study on the expert system based process planning of the block division process in shipbuilding. The prototype system developed deterines the block division line of the midship of crude-oil tanker. Case-based reasoning (CBR) approach relying on previous similar cases to solve the problem is applied instead of rule-based reasoning (RBR). Similar cases are retrieved from case base according to the similarity metrics between input problem and cases. The retrieved case with the highest priority is then adapted to fit to the input problem buy adaptation rules. The adapted solution is proposed as the division line for the input problem.

적조 현상에 대한 판별, 예측 분석을 위한 시스템은 현재 개발이 아주 미흡한 상태이고 현재의 적조원인에 대한 연구는 화학 및 생물학적 원인의 규명에 대해 그 초점이 맞추어져 있어 지능적인 의사 결정 알고리즘을 갖는 시스템 구현이 필요하다. 본 논문에서는 사례 기반 추론 기법을 이용하여 적조 현상에 관한 사례를 지식 베이스로 구축하고 추론하는 시스템을 설계하였다. 가장 유사한 사례 추천을 위해 KNN 알고리즘을 이용하였고 적조 사례 베이스를 구축하기 위하여 375 건의 데이터를 입력 받아 실험하였다. 학습 데이터로부터의 영향을 최소화하고 신뢰성을 확보하기 위해 10-Fold 교차검증을 수행한 결과 적조 사례에 대한 평균 정확도는 약 84.2%를 나타냈고 유사도 분류 k 개수가 5인 경우에 최적의 수행 결과를 나타냈다. 또한, 추론된 결과를 이용하여 적조 모니터링 시스템을 구현하였다.

This paper introduces an enhanced condition monitoring and diagnosis system recently developed for rotating machinery. In the system, the data aquisition/monitoring signal processing, machine condition classifier, case-based reasoning and demonstration modules are effectively integrated with user-friendliness so that machine operators can easily monitor and diagnose the status of rotating machinery in operation. Some of the new features include the directional spectrum, case-based reasoning and neural network techniques. And the demonstrator modules for fault diagnosis of a Bear driving system and for basic understanding of the rotor dynamics are provided to help the potential users better understand the system.

In order to adapt to today's rapidly changing environment and gain a competitive advantage, many companies are interested in CRM(Customer Relationship Management). Especially, the product recommendation system that can be implemented by personalizing the marketing strategy becomes the focus of CRM. In this research, we employed CBR(Case-Based Reasoning) technique that can overcome the limitation of CF(Collaborative Filtering) technique. Our system recommends the books that the customer is very likely to buy next time considering the factors such as 'Personal Features of Customer,' Similarity between Book Categories' and 'Sequence of Book Purchases'. Accuracy of predicting a book-not a particular book, but in the middle level of classification that contains about 190 categories-was about 57%.

A workflow model is useful fur business process analysis and has often been implemented for office automation through information technology. Accordingly, the results of workflow modeling need to be systematically managed as information assets. In order to manage the modeling process effectively, it is necessary to enhance the efficiency of their reuse. Therefore, this paper creates a Document-barred Workflow Modeling Support System (DWMSS) using a case-based reasoning (CBR) approach. It proposes a system architecture, and the corresponding modeling process is developed. Furthermore, a repository, which consists of a case base and vocabulary base, is built. A carte study is illustrated to demonstrate the usefulness of th is system.
