복잡한 분야의 한정된 데이터 상황에서의 사례기반 추론 : 공정제어 분야의 적용

Perhaps one of the most versatile approaches to learning in practical domains lies in case based reasoning. To date, however, most case based reasoning systems have tended to focus on relatively simple domains. The current study involves the development of a decision support system for a complex production process with a limited database. This paper presents a set of critical issues underlying CBR, then explores their consequences for a complex domain. Finally, the performance of the system is examined for resolving various types of quality control problems.

The purpose of this study is to analyze the dental treatment records of the disabled in Wonju Severance Christian Hospital, Korea for five years and utilize them as basic data for expanding medical services for the disabled. The electronic medical records of first oral examination for five years at department of pediatric dentistry were analyzed targeting the patients with mental retardation, brain lesions, autism, and mental disorder. In case of patients with single disability, it was found that there were 86 patients with mental retardation (55.1%), 28 patients with brain lesions (17.9%), 18 patients with autism (11.5%), and 2 patients with mental disorder (1.3%). In method of behavior management, there were 205 sedations (51.3%), 124 tell-show-do or protective stabilizations (31.0%), and 71 general anesthesia (17.8%). In case of sedation, most were midazolam intramuscular (192 cases, 93.7%), and waiting time after administration was 23.5 min (± 9.5 min) on average, and the treatment time was 36.3 min (± 17.2 min) on average. In general anesthesia, anesthesia time was 233.1 min (± 99.0 min) on average, and treatment time was 195.5 min (± 96.8 min) on average. Dental treatment specialized in the characteristics and demands of the disabled is very important, and social support for this is necessary. This study may be used as reference data in Korea for expanding medical services for the disabled in the future.

본 논문에서는 내용 기반 음악의 감성추출 연구의 동향을 살펴보고, 평가치를 기반으로 청중의 기호를 분석해 본다. 청중의 기호 분석은 가능한 많은 사람이 공감 할 수 있는 데이터를 사용하고자, 최근 이슈가 되고 있는 「나는 가수다」방송 프로그램의 음원 분석을 통해 이루어졌다. 데이터베이스는 총 7 번의 공연/경연마다 7 곡씩 순위가 매겨지므로 총 49 곡으로 이루어진다. 청중 평가단은 총 500 명의 엄격히 선발된 10 대에서 50 대, 각각 100 명 씩으로 구성되었다. 특징값은 오픈소스인 MIRtoolbox 를 이용해서, 총 376 개의 특징값을 추출하여 평가치와의 상관관계를 구해 청중 평가단의 기호를 분석한다. 실험결과 총 376 개의 특징값 중 10 개의 특징값이 청중평가단의 기호와 상관관계가 있다는 것이 나타났다. 마지막으로 내용 기반 음악의 감성 추출 연구에서 보이는 감성의 주관적 인식성 및 심리학적 설명의 난해함을 줄이고자, 향후 과제로 내용 기반 및 평가치 기반의 시스템을 결합한 감성 기반 음악 추천 시스템을 제안한다.

Objectives: This study aims to find out the association between Sasang and Eight Constitution by analyzing Sasang and Eight Constitution Diagnosis results. Methods: We analyzed Sasang and Eight Constitution Diagnosis results according to confidence, by reviewing medical records of 247 patients retrospectively whose Sasang and Eight constitutions were diagnosed by two independent specialists. We used chi -square test and Cramer Statistic to know association of two diagnosis results. Results and Conclusions: Taeumin was 49.8% in Jupita, Soeumin 65.2% in Mercuria, Soyangin 90.9% in Saturna. Taeumin was 54.2% in Jupita, Soeumin 83.4% in Mercuria, Soyangin 100% in Satuma in condition that Sasang and Eight Constitution diagnosis confidence is over Band 50 score. The higher diagnosis confidence is, also the higher association between Sasang and Eight Constitution is up to 0.414(Cramer Statistic). There is association between Sasang and Eight Constitution.
