SELIS(SEoul Women's University Library and Information System) OPAC에 대한 이용자의 키워드/불연산자 탐색의 지식수준을 알아보기 위하여 4가지 사항에 따라 질문지의 결과를 분석하였다. 분석한 결과를 보면 SELIS OPAC 이용시 키워드 탐색에서 불연산자의 사용이 쉽다고 생각하고 불연산자의 사용으로 검색결과를 만족하는 이용자는 그렇지 않다고 응답한 이용자 보다 키워드/불연산 탐색의 지식수준이 높은 것으로 요약할 수 있다. 설문문항에서 제시한 지식은 키워드 탐색의 특성(단일 키워드 사용, 2개 이상의 키워드 사용), 키워드 탐색 시 불연산자의 사용, 색인에 대한 지식, 불용어 리스트에 대한 지식(비통제 용어) 키워드 탐색기법(전방일치, 우측절단). 불연산자의 올바른 사용, 키워드의 브라우징으로 주제어 선정에 관한 것이다. 앞에서 제시한 이러한 지식들은 OPAC의 키워드/불연산자 탐색에서 중요한 요소로 볼 수 있다. 성공적인 탐색을 위해서는 정보검색과정에 대한 개념적인 지식 즉, 정보요구를 탐색 가능한 질의어로 바꾸는 것과 주어진 시스템에서 질문의 결과를 얻는 방법에 대한 어의적인 지식(시스템의 특징을 어떻게 언제 이용할 것인가 하는 지식) 그리고 이용자의 질문에 대한 과학적인 기술 즉, 기본적인 컴퓨터 기술과 상세한 탐색문을 작성하는 구문론적인 지식이 요구된다. 그러나 지금까지 이용자에 대한 온라인목록 탐색의 중요한 지식으로 간주해온 것은 과학적인 기술방법에 관한 지식에만 치중하고 어의적인 지식, 개념적인 지식을 강조하는 것은 부족하였다. 따라서 온라인목록 이용에 관한 교육을 너무 과학적인 기법에만 치중할 것이 아니라 어의적 지식, 구문에 관한 기술과 개념적인 지식 교육에 초점을 맞추어야 할 것이다.

Objectives : The aim of the study is to investigate the oral health knowledge, attitude and dental caries experience in Korean 12-year-old adolescents. Methods : The subjects were 2,196 adolescents living in Seosan, with an average age of 12.2 years. Data were collected using a self-administered questionnaire from April 10 through June 10, 2011. A trained investigator made an oral examination of them in natural light, using a mirror and an explorer to determine their DMFT index. Results : The prevalence rate of dental caries of adolescents was 59.1%. The DMFT index of the subjects was 1.98, which was lower than the national mean of 2.2 for the same age. The DMFT index was significantly higher in the female(2.25) than the male group(1.72). The attitude of oral health was positively related to DMFT index in this study(OR=1.25; CI=1.01-1.54). It appears that knowledge and attitude concerning oral health, among young Korean 12-year-old adolescents living in Seosan, are in need of improvement. Conclusions : Based on the findings, dental caries experience is associated with attitude of oral health. This result suggests that the implementation of oral health promotion should be considered for various factors related to attitude of oral health in adolescents.

Objectives: The objective of the study was to investigate oral health index between adequate and inadequate dental care following preventive scaling in regular dental check-up and management. Methods: The subjects in Busan were assigned to two groups including inadequate dental care (140 patients) and adequate dental care (88 patients) after preventive scaling from January 2014 to June 2015. The study instruments included oral health knowledge, awareness, practice, and community periodontal index of treatment needs (CPITN). Results: CPITN was significantly different between the two groups (p<0.05). Positive correlations were found in oral heath knowledge and awareness (r=0.462, p<0.05) before application of preventive scaling. There was a close correlation in oral health awareness and practice (r=0.205, p<0.05) before application of preventive scaling. After application of preventive scaling, oral health knowledge and awareness showed positive correlation (r=0.643, p<0.05). After application of preventive scaling, there was also a close correlation between oral health knowledge and practice (r=0.453, p<0.05). Oral health awareness and practice (r=0.512, p<0.05) showed positive correlation after the application of preventive scaling. However, oral health practice and CPITN (r=-0.189, p<0.05) showed a negative correlation. Conclusions: Practice made periodontal condition improve. To promote oral health practice in the group without adequate dental care, it is necessary to pay attention to adequate dental care and preventive scaling through education by dental hygienists.

An intelligent system embedded with multiple sources of knowledge may provide more robust intelligence with highly ill structured problems than the system with a single source of knowledge. This paper proposes the hybrid knowledge integration mechanism that yields the cooperated knowledge by integrating expert, user, and machine knowledge within the fuzzy logic-driven framework, and then refines it with a genetic algorithm (GA) to enhance the reasoning performance. The proposed knowledge integration mechanism is applied for the prediction of Korea stock price index (KOSPI). Empirical results show that the proposed mechanism can make an intelligent system with the more adaptable and robust intelligence.

The purpose of this study was to assess how mothers' oral health behaviour, knowledge, and socio-demographic characteristics influence on dental caries status of their children. The 142 children and their mothers were selected for this study. The children were 5 and 6 years old in the three day care centers in Ulsan, Korea. Date were collected by oral examination on children and self-administrated questionnaire on their mothers. The questionnaire was surveyed mothers' behaviour and know ledge of oral health and their socio-demographic characteristics. The findings of this study were summarized as follows: 1. The higher mother's educational level and the greater children members, the higher degree of oral health knowledge, but there was no significant relation. 2. There was significant relationship between working mothers and correct toothbrushing, between monthly mean income and important for oral health. 3. The dft index was lower when the higher mother's oral health knowledge, the larger toothbrushing frequency, preventive dental visit.

Effective energy consumption now becomes one of the area of knowledge management which potentially gives global impact. It is considerable for the energy management to optimize the usage of energy, rather than decreasing energy consumption at any cases. To resolve these challenges, an intelligent and personalized system which helps the individuals control their own behaviors in an optimal and timely manner is needed. So far, however, since the legacy energy management systems are nation-wide or organizational, individual-level energy management is nearly impossible. Moreover, most estimating methods of energy consumption are based on forecasting techniques which tend to risky or analysis models which may not be provided in a timely manner. Hence, the purpose of this paper is to propose a novel individual-level energy management system which aims to realize timely and personalized energy management based on context-aware computing approach. To do so, an index model for energy consumption is proposed with a corresponding service framework.

This study was intended to assess the effects of low glycemic index (LGI) nutrition education on dietary management and glycemic control of patients with type 2 diabetes mellitus. The subjects were 48 sex-matched patients with type 2 diabetes mellitus, aged $66.5\;{\pm}\;6.2$ years, visiting a public health center. They were divided into two groups: the control group (males 10, females 14) and the educated group (males 10, females 14). The educated group was provided with a LGI nutrition education program for 7 weeks. The control group was educated only one time for general diabetic education. Anthropometric indices, knowledge and perception of efficacy of low glycemic index carbohydrates, dietary glycemic index (DGI) and glycemic load (DGL), fasting blood glucose, and HbA1c were assessed. In the educated group body weight, body mass index and systolic blood pressure (from $138.0\;{\pm}\;18.9\;mmHg$ to $130.6\;{\pm}\;15.0\;mmHg$) were significantly reduced after the nutrition education (p < 0.05). The scores of knowledge and perception of efficacy of low glycemic index carbohydrates increased significantly in the educated group. Dietary glycemic index and glycemic load of the educated group decreased significantly from $103.4\;{\pm}\;67.6$ to $45.4\;{\pm}\;27.1$ (p < 0.001), and from $173.3\;{\pm}\;135.9$ to $66.8\;{\pm}\;50.4$ (p < 0.001), respectively. Also fasting blood glucose and HbA1c levels of the educated group significantly decreased from $124.5\;{\pm}\;28.8\;mg/dL$ to $96.7\;{\pm}\;21.6\;mg/dL$ (p < 0.001) and from $7.1\;{\pm}\;1.3%$ to $6.4\;{\pm}\;1.2%$ (p < 0.05), respectively. The score of knowledge and perception of efficacy of low glycemic index significantly correlated with fasting blood glucose and HbA1c levels negatively. DGI, DGL and duration of diabetes significantly correlated with HbA1c level positively. From stepwise multiple linear regression analysis, DGI, DGL and the duration of diabetes were extracted as factors influencing HbA1c level of the subjects. The results of this study suggest that low glycemic index nutrition education programs is an effective intervention measure for the glycemic control in type 2 diabetic patients.
