This study proposed an SCA advice system. It is an ontology-based recommender that provides advice on appropriate computer curricula based on the behavior of high school students. The three computer curricula at Chiang Mai Rajabhat University include computer science (CS), information technology (IT), and web programming and security (WEB). This study aims to design the ontology framework for an SCA advice system. The system considers three core ontologies: student, computer-curriculum, and advice. After analyzing student behaviors, the behavior types of CS, IT, and WEB were determined to be SB-2, SB-1, and SB-5, respectively. All subjects in these three curricula were analyzed and grouped into seven groups. Their curricula were synthesized in terms of basic skills, basic knowledge, and characteristics. Finally, advice results can be obtained by consolidating the curriculum nature of the CS, IT, and WEB curricula.

다양한 빅데이터 기술이 발전함에 따라, 기업의 전략결정에 있어서 과거에는 의사결정자의 직관이나 경험에 의존하는 경향이 있었다면, 현재는 데이터를 활용한 과학적이고 분석적인 접근이 이루어지고 있다. 이에 많은 기업들이 경영정보시스템 중의 하나인 비즈니스 인텔리전스 (Business Intelligence) 시스템의 예측분석 기능을 활용하고 있다. 하지만, 이러한 시스템이 미래의 경영환경 변화를 예측하고 기업의 의사결정을 돕는 조언자 (Advisor)로서 역할을 한다고 가정할 때, 시스템에서 제공하는 분석결과가 의사결정자에게 도움을 주는 조언 (Advice) 의 역할을 하지 못하는 경우가 많은 실정이다. 따라서, 본 연구에서는 미래예측의 문제에 있어 의사결정자가 시스템의 조언을 따르는데 영향을 미치는 요소들과 영향력에 대해 분석하고, 그 결과를 바탕으로 데이터 기반의 의사결정을 보다 적극적으로 지원하는 시스템 환경을 제시하고자 한다. 좀 더 구체적으로는 예측 과정에 대한 자세한 설명이나 근거 제시가 시스템의 예측결과에 대한 의사결정자의 수용정도에 미치는 영향을 연구하였다. 이를 위하여 193명의 실험자를 대상으로 영화의 개봉 주 매출액을 예측하는 업무를 수행하고, 예측에 대한 설명의 길이와 조언자의 유형(사람과 시스템의 조언 비교)뿐 아니라 의사결정자의 개인 특성이 의사결정자의 조언 수용정도에 미치는 영향을 분석하였다. 시스템에서 제공하는 조언 내용인 예측결과와 설명에 대해 의사결정가가 느끼는 유용성, 신뢰성, 만족도가 조언의 수용에 미치는 영향도 분석하였다. 본 연구는 시스템의 분석결과를 조언으로 보고 조언자와 조언에 관한 의사결정학 분야의 선행연구를 접목시켜 경영정보시스템 연구 분야를 확장하였다는 점에서 연구의 의의가 있고, 실무적으로도 데이터 기반의 의사결정을 보다 적극적으로 지원할 수 있는 시스템 환경을 만들기 위해서 고려해야 할 점들을 제시함으로써 시스템 활용을 위한 정책결정에도 도움을 줄 수 있을 것으로 본다.

Emergency Medical Service(EMS) requires a system that supports the communication between emergency medical technicians (EMT)s and the doctor in the emergency department. Because the rapid triage and on-site treatment of patients need doctor's medical advice. However, a system to assist the doctor assign for medical advice does not exist in Korea. This paper suggests a medical advice support system that focuses on appropriate doctor assign and real-time communication among the ambulance, the Emergency Medical Information Center (EMIC), and the doctor using an agent system. We expect that the system can help to solve the problems affecting prehospital EMS and improve its general quality.

This paper describes an adaptive recommendation system that provides real-time personalized trading advice to the investors based on their profiles and trading information environment. A proposed system integrates Stochastic technical analysis and artificial neural network that incorporates an adaptive user modeling. The user model is constructed and updated based on initial user profile and recorded user interactions with the system. The information presented to each individual user is also tailor-made to fit the user's behavior and preference. A system prototype was implemented in JAVA. Experiments used to evaluate the system's performance were done on both human subjects and synthetic users. The results show our proposed system is able to rapidly learn to provide appropriate advice to different types of users.

This research broadens the prime concern of nuclear power plant operations from safe performance to both economic and safe performance. First emergency diesel generator is identified as one of main contributors for the lost plant availability through the review of plants forced outage records. The framework of an integrated architecture for performing modern on-line condition for operational availability improvement is configured in this work. For the development of the comprehensive sensor networks for complex target systems, an integrated methodology incorporating a structural hierarchy, a functional hierarchy, and a fault-system matrix is formulated. The second part of our research is development of intelligent diagnosis and maintenance advisory system, which employs Bayesian Belief networks (BBNs) as a high level reasoning tool incorporating inherent uncertainty use in probabilistic inference. Our prototype diagnosis algorithms are represented explicitly through topological symbols and links between them in a causal direction. As new evidence from sensor network development is entered into the model especially, our advisory of system provides operational advice concerning both availability and safety, so that the operator is able to determine the likely modes, diagnose the system state, locate root causes, and take the most advantageous action. Thereby, this advice improves operational availability

Children's health is interesting to parents and society. A system that assists to monitor the development of their children and gives nutritional advices is an interesting of parents. In this study, we present a system that allows to track the heights and weights of a child since he/she was born up to adulthood, to predict his age of puberty, and to provide nutritional advice. Particularly, it predicts the height in near future and the adult stature for detecting the child with abnormal development. We applied Sager's model for predicting the height in near future by using interpolation and regression techniques before puberty. After determining the puberty time, we proposed a model for predicting the height. Then we applied fuzzy logic for evaluating the health status and providing nutritional advice. Our system predicted stature in near future with error bound of $1.7361{\pm}0.0397cm$ in girls and $2.4020{\pm}0.0799cm$ in boys. Our model also gave a reliable adult stature prediction with error bound of $0.3507{\pm}0.2808cm$ in girls and $1.3414{\pm}0.7024cm$ in boys. At the same time, the nutrition was provided appropriately in terms of protein, lipid, glucid. We implemented a program based on this research. Our system promises to improve the health of every child.

Background : The objective of this study is proving the basic data for developing a management system for the discharges against medical advice(AMA) by identifying the characteristics of the AMA patients of an university hospital for 10 years. Methods : By using discharge abstract data base, we divided the total discharges(435,254) into two groups, discharge against medical advice and discharge with discharge order. We confirmed the characteristics of AMA group by analyzing discharge abstract data of the both groups by SAS software V6.12 and $x^2$ test. Medical records of AMA patients in the year 2000 were reviewed to identify the reasons for AMA which we couldn't extract from discharge abstract DB. Result : The total number of AMA for 10 years were 9,358(2.15%) and the AMA rate has been continuously decreased for 10 years. Male, admission through emergency room, discharges admission via other hospital, patients without operation during hospitalization, discharges in hopeless or not improved condition showed higher AMA rate. The AMA rate was higher as the age of the patients was higher, and the average length of stay was longer in AMA patients than in those with discharge order. The AMA rate in psychiatry was highest(14.3%) and it was higher in surgery departments than those of medical or other sections. The AMA rate varied by attending physicians even in the same department and it was statistically significant. Patients with the principal diagnosis of "medical observation and evaluation for suspected diseases" showed the highest AMA rate(15.5%), and that of schizophrenia or psychosis was the nest. One hundred twenty-one patients(19.5%) out of 622 AMA in 2000 discharged against medical advice for transfer to order health care facilities. Among them 71 patients(58.7%) discharged with their medical care information, such as copies of medical record, medical certificates, summaries, etc. Written oath of the patients discharged AMA was filed in their medical records in 466 cases(74.9%) although some of them were incomplete. Conclusion : Characteristics of AMA discharge could be used as the basic data in developing a system to manage the patients who have risk factors to leave the hospital against medical advice. By reducing number of patients leaving the hospital against medical advice we can increase satisfaction of medical providers and consumers.
