Conceptual and procedural knowledge of integration is necessary not only in calculus but also in real analysis, complex analysis, and differential geometry. However, students show not only focused understanding of procedural knowledge but also limited understanding on conceptual knowledge of integration. So they are good at computation but don't recognize link between several concepts. In particular, Riemann sum is helpful in solving applied problem, but students are poor at understanding structure of Riemann sum. In this study, we try to investigate understanding on conceptual and procedural knowledge of integration and to analyze errors. Conducting experimental class of Riemann sum, we investigate the understanding of Riemann sum structure and so present the implications about improvement of integration teaching.

Purpose: The purpose of this study was to investigate the degree and pattern of knowledge management process, and to identify the relationship between knowledge management process and organizational effectiveness in clinical nurses. Method: Participants were 665 regular clinical nurses who had worked for over 1 year in general units of 9 tertiary medical hospitals including 2 national university hospitals, 5 university hospitals, and 2 hospitals founded by business enterprises. Data were collected from March to May 2003 through questionnaires. Four structured instruments were used to collect the data: Knowledge Management Process Scale(Jeong, Lee, Lee, & Kim, 2003), cCommitment Questionnaire(Mowday, Steers, & Porter, 1979), General Satisfaction Scale(CooK, Hepworth, Wall, & Warr, 1981), and one for general characteristics. The data were analyzed using factor analysis, reliability analysis, descriptive analysis, cluster analysis, one-way ANOVA, Scheffe test, correlation analysis with the SPSS for Windows 10.0 program. Result: 1) The average score for knowledge management process in nurses was $3.08{\pm}.54$ on a 5-point Likert scale. In order from highest mean score, the elements of knowledge management process, were Knowledge $Utilization(3.35{\pm}.57)$, Knowledge $Sharing(3.07{\pm}.58)$, Knowledge $Creation(2.99{\pm}.63)$, and Knowledge $Storage(2.91{\pm}.82)$. 2) Four knowledge management patterns for nurses, which were derived from cluster analysis, were inactivate pattern, delayed pattern, activate pattern, and high-activate pattern of knowledge management. 3) The degree of knowledge management process activation and 4 elements of knowledge management process, Knowledge Creation, Knowledge Storage, Knowledge Sharing, and Knowledge Utilization, were significantly correlated with nurses' organizational commitment and job satisfaction(p=.000). 4) The nurses' organizational commitment and job satisfaction showed significant differences according to the knowledge management patterns derived from cluster analysis of high-activate pattern, activate pattern, delayed pattern, inactivate pattern(p=.000). Conclusion: These results suggest that there are four knowledge management patterns for nurses, and knowledge management process positively affects the nurses' organizational commitment and job satisfaction. From the above findings, knowledge management process is empirically verified as a useful and effective method to increase organizational effectiveness, and develop the organization.

This study was conducted to test whether a comprehensive health promotion program for promotion strategies and knowledge about the disease, thus leading to the improvement of health status by using repeated measure of quasi- experiment design. Eighteen RA patients who visited the RA clinic of an university hospital located in Inchon were invited to participate in the CHPPRA. According to the study results, it was shown that the CHPPRA had significant effects on the patients' health status such as pain, depression, and functional disability. Also, that the improvement of health status was achieved by a positive change in the four health promotion strategies, which consisted of goal setting, positive thinking, exercise, and knowledge about the disease. Goal setting, positive thinking, and knowledge about the disease could also affect the patients' depression. Thus it can be interpreted that the improvement of these strategies may result in a remarkable decrease of depression. In addition, alleviation of functional disability may be due to increase of exercise. However although the strategies which were directly associated with pain management were not significantly improved, pain was significantly reduced. On the other hand, the study result showed that the other health promotion strategies included in CHPPRA such as pain management, positive thinking, stress management, asking for assistance and communication were not significantly increased. although the health status such as pain, depression, and functional disability, which are final goals of the program, were significantly improved through the exposition of patients to those health promotion strategies.

The subjects were selected among applicants for low-income family financing of the government and included 90 children and their parents. they were divided into 2 groups (less than 6 months and more than 6 months of participation in the study). We analyzed the effects of NutriPlus program and nutrition education in both study groups. The results of this study were summarized as follows: The number of children with less than 10th percentile in height and weight and weight for height was decreased. The anemia prevalence rate was reduced from 64.4% to 8.9%. NAR value of subjects increased for energy, protein, calcium, iron, vitamin A, riboflavin, niacin and vitamin C. The education program improved knowledge and attitude of the parents. In nutrition knowledge according to the income level, there were greater changes in the group of less than 100% compared to the subsistence. In nutrition attitude according to the education level, there were greater changes in the group of middle school graduates than in high school graduates or college graduates. There were no difference between less than 6 months group and more than 6 months group in improvement of hemoglobin level, anthropometric data and nutrients intakes. Based on these results, we conclude that providing supplementary food to children and nutrition education brought positive effects on growth of the children.

Rapid knowledge change, heightened competition. and shortened product life cycles are just a few of the constants faced by many buying firms in today's markets. Many buying firms have responded to these conditions by outsourcing non-core activities. The Quality and cost of a product or service offered in the market is a function, not only of the capabilities of the firm, but also of the network of suppliers who provide inputs to the firm. When a firm finds its suppliers lacking in performance it can help suppliers to develop their capabilities. There are three main goals for this study. The first goal is to identify the important factors that precede and influence firms' investment in knowledge transfer activities. The second goal is to investigate the relationship between knowledge transfer activities and the consequences of knowledge transfer activities. The last goal is to explore the effects of knowledge change speed. To analyze the validity of the research model and the hypotheses. the data are collected from 238 manufacturing firms through the administration of structured Questionnaires. The results of structural equation model analyses indicate that the model is generally valid and 11 of 14 hypotheses are supported by the data. Reasons for and implications of these observed relationships are discussed.

Data are an expression of the language or numerical values that show some features. And the information is extracted from data for the specific purposes. The knowledge is utilized as information to construct rules that recognize patterns or make a decision. Today, knowledge extraction and application of that are broadly accomplished for the easy comprehension and the performance improvement of systems in the several industrial fields. The knowledge extraction can be achieved by some steps that include the knowledge acquisition, expression, and implementation. Such extracted knowledge is drawn by rules with data mining techniques. Clustering (CL), input space partition (ISP), neuro-fuzzy (NF), neural network (NN), extension matrix (EM), etc. are employed for the knowledge expression based upon rules. In this paper, the various approaches of the knowledge extraction are surveyed and categorized by methodologies and applied industrial fields. Also, the trend and examples of each approaches are shown in the tables and graphes using the categories such as CL, ISP, NF, NN, EM, and so on.
