The objective of this paper is to develop a knowledge assets measurement model in Korea. There are relatively many researches on measuring knowledge assets of an organization. These previous researches, however, lack of comprehensive view of knowledge management and view of Korean organizational culture. We surveyed and analyzed previous researches, and found common factors to measure knowledge assets. We developed an updated version of knowledge assets index. The developed model has been validated for its fitness with real data of Korean companies. The result of this research can be used as a measurement tool for knowledge assets of public institutions as well as private companies.

Knowledge management can be defined as the valuable storing and creation of new knowledge, as well as the sharing of this knowledge to be applied in all areas of an organization's management activities (Turban et al., 2003). In a knowledge-based society where intangible intellectual assets are the source of competitive advantage rather than tangible assets, knowledge management activities are emphasized in both academia and industry. This study analyzes research on "knowledge management" keyword indexed in the Korean Citation Index (https://kci.go.kr), operated by the National Research Foundation of Korea (NRF), to identify related research trends in Korea and suggest future directions for knowledge management activities. The results show that knowledge management is being researched through the integration of various fields and theories, indicating the potential for expanding research topics and fostering interdisciplinary collaboration. Furthermore, the study of knowledge management often include the keyword 'innovation', emphasizing its significant role in organizational and technological innovations. The analysis of keywords by year also reveals that they reflect the major environmental changes of each period, demonstrating the increasing importance of knowledge management in the era of the Fourth Industrial Revolution.

The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.

This paper presents a knowledge based system to solve reactive power/voltage control problem in a power system. A need is recognized for new methods to alleviate a bus voltage limit violation more quickly when a power system becomes an emergency state due to contingency. To cope with this object, a set of indices concept which is used to make bus order list of reactive power injection priority is introduced. A set of indices, based on the overall system conditions, consists of steady state stability index, reactive power transmittance indes, voltage severity index and generator fuel cost index. This scheme and empirical rules of the knowledge on the basis of the human expert result in fast decision-making of the reactive power compensation devices since only the amount of devices is determined by the inference in the knowledge based system when the voltage violation is detected. In this approach, control devices such as shunt capacitor (reactor), transformer tap settings and generator voltages are utilized. Also the developed system herein can be used to minimize control action taken or generator fuel cost according to the user's option on the weighting factor. The results of a case study are also presented.

In recent years, construction projects have been forced to cope with lack of skilled labor and increasing hazard circumstance of human operations. A construction robotic system has been frequently accomplished as one alterative for overcoming these difficulties in increasing construction quality, enhancing productivity, and improving safety. However, while the complexity of such a system increases, there are few ways to carry out an assessment of the system. This paper introduces a knowledge-based multi-criteria decision-making process to assist decision makers in systematically evaluating an automated system for a given project and quantifying its system performance index. The model employs linguistic terms and fuzzy numbers in attempts to deal with the vagueness inherent in experts' or decision makers' subjective opinions, considering the contribution resulted from their knowledge on a decision problem. As an illustrative case, the system, called Robotic-based Construction Automation, for constructing steel erection of high-rise buildings was applied into this model. The results show the model's capacities and imply the application to other extended types of construction robotic systems.

Objectives : The purpose of this survey research was to investigate the relationship among oral health State, behavior and knowledge of oral health of patients who participate in dental hygiene students voluntarily. Methods : The subject in this were patients who got a scaling at the oral hygiene practice lab in the department of dental hygiene in S university dental clinic from April 1 to May 31, 2010. For the data analysis, an SPSS WIN 11.5 program was used and its signification level was 0.05. Results : 1. For the oral health state according to sex distinction, it showed the men's 0.78 MT index was higher than women's 0.48 MT index and statistically significant difference. For FT index, women(4.72) was higher than men(3.50) and it showed statistically significant difference(p<0.05). 2. For the oral health state according to age distinction, DT index of under 20years(2.44) was higher than the others and it showed statistically significant difference(p<0.05). 3. For the oral health state according to marriage distinction, not married DT index(1.59) was higher than married DT index(2.56) and it showed statistically significant difference(p<0.05). 4. For the oral health behavior according to age distinction, 87.0% 20~29years patients replied as I have experience of my teeth scaled and it showed statistically significant difference. 18.5% more than 30 years replied as I use interdental brush and it showed statistically significant difference. 18.5% more than 30 years replied as I use powered brush and it showed statistically significant difference(p<0.05). 5. For the oral health state according to oral health behavior distinction, there were significant difference that regular visit of dental clinic, experience of teeth scaled, toothbrushing, oral hygiene device(p<0.05). 6. For the oral health state according to oral health knowledge distinction, there were significant difference that toothbrushing time after each meal, appropriate toothbrushing time, toothbrushing method, dental caries foods(p<0.05). Conclusions : I suggest with the result of the study that there was a very close relationship between oral health status, behavior and knowledge of oral health. Therefore student of the dental hygiene should be encouraged to pay more attention to oral health care of the patient, and they should be well educated oral health care personnels who volunteers in practice for oral prophylaxis.

This study aims to measure oral health knowledge and practice level among dental clinic patients, and examine their relationships with decayed, missing and filled teeth (DMF) index and the oral health-related quality of life (QOL). Empirical data have been collected from 311 patients through structured questionnaires and dental examinations conducted in Busan area. According to the analysis of causal relationship, oral health knowledge turned out to have a direct effect on oral health practices, which exerted both direct and indirect effects on DMF index and oral health-related QOL. While DMF index directly affected the oral health-related QOL, oral health knowledge proved to have only an indirect effect on DMF index and oral health-related QOL, mediated by oral health practices. Considering all these findings, effective oral health education and other intervention programs should focus on motivating people to participate in the active practices of desirable oral health behaviors, which will lead to the prevention of oral diseases and the subsequent improvement in the QOL.

Recently, many of organizations build up their performance measurement system (PMS) to measure their knowledge management performance. However, the system that doesn't well reflect the organization's strategies as well as surroundings could obstruct their performance improvement, instead. Therefore, It is really important to establish the PMS to reflect organization's surroundings and strategies. The purpose of this study is to make a diagnosis of a performance measurement practice of a domestic university's knowledge management. To serve this research purpose, we examine the uptight performance index and PMS from existing references. And we diagnose the specific practices and maturity rates of measuring performances, and the recognition of the performance index at "D" university recently adopting balanced scorecard to performance evaluation through the survey on academic affairs committee members, performance evaluation committee members, and administration members. The method analyzing data from the survey is a gap analysis which includes alignment analysis, congruence analysis, consensus analysis, and confusion analysis. We make a diagnosis of performance measurement practices at "D" university, raise several points of this performance measurement system, and present the improvement plans from these problems.

The purpose of this study was to investigate dietary attitudes food behaviors and nutrition knowledge of food nutrition major and non-major female students. The subjects of this study consisted of 98 food and nutrition majors and 98 non-majors. Questionnaires were completed by them. Food and nutrition majors gave a serious consideration of taste and nutrition in selecting foods while non-majors considered taste food price amount of food and preparing time. Food and nutrition majors got higher scores in hig-her level of nutrition knowledge than non-majors and both got about the same scores in basic nutrition knowledge. The mean body weights of both were about the same and mean height of non-majors was hig-her than food and nutrition majors. Accrding to obesity index ideal body weight was more in food and nutrition ajors and underweight was more in non-majors. Dietary attitudes food behaviors and nu-trition knowledge of food and nutrition majors were better than those of non-majors. Therefore nutrition non-majors need nutrition education in order to improve their food behaviors and nutrition knowledge.

This study was conducted to investigate the effectiveness of a nutrition and exercise education program on weight control and nutrition knowledge. The nutrition-exercise educational period was 12 weeks. The subjects were 160 adult women with an average age of 48.1 years. We investigated general characteristics, diet history, eating habits, and intake frequencies of six food groups by survey. A total of 94 women among the subjects participated in the pre and post nutrition knowledge evaluations and anthropometric data assessment. After the program, body weight, body mass index (BMI), and waist circumference significantly decreased. Further, % of body fat decreased, but not significantly. BMI significantly decreased (p<0.001) from 25.14 to $24.80kg/m^2$, and waist circumference significantly decreased (p<0.001) from 79.72 to 77.63 cm. The nutrition knowledge scores of subjects significantly increased (p<0.001) from 8.01 to 9.03. However, there was little change in employment. These results suggest that the nutrition-exercise education program may improve obesity index and nutrition knowledge. However, it is necessary to develop a specialized weight control program for workers.
