Leaf springs are widely used as a major suspension component in many commercial vehicles, such as buses, trucks, etc. They have a complex dynamic behavior due to the geometric nonlinear and the contact mechanism between the leaves. The interface conditions between the leaves play a significant role in the global behavior of the comfort and ride of the vehicle system. The paper concentrates on modeling leaf springs and contact frictions between the leaves using a nonlinear finite element approach. A nonlinear load-displacement hysteresis curve for the leaf spring is simulated and its results are compared with test results.

Each robot plays a role of its own behavior in dynamic robot-soccer environment. One of the most necessary conditions to win a game is control of robot movement. In this paper we suggest a win strategy using Cellular Neural Network to set optimal path and cooperative behavior, which divides a soccer ground into grid-cell based ground and has robots move a next grid-cell along the optimal path to approach the moving target.

Purpose The purpose of this paper is to examine factors and mechanism inducing end users' faithful appropriation of information security behavior through the information security system. This study is also trying to find out the role of Employees' adaptive activities like learning and feedback seeking behavior for the information security in organizations. Design/methodology/approach An empirical study was carried out with a sample of employees working in the financial service company. Employees(n = 268) completed a written questionnaire. Structural equation modeling was used to analyze the data. Findings Results indicated that employees' learning activities and feedback seeking behavior fully mediated the effect of major information security factors toward end users' faithfulness of appropriation of information security systems. In order to increase the level of employees information security behavior in accordance with security guideline, organizations should facilitate interactions that support the feedback seeking process between employees on information security awareness and behavior. Additionally, organizations may reinforce these behaviors by periodical training and adopting bounty hunter systems.

Purpose: This study was performed to examine predictors of allied health science students' exercise behavior using Pender's Health Promotion Model. Method: The subjects were 203 university students majoring in nursing, emergency medical service, and exercise prescription. The hypothetical model was based on the HPM(Pender, 1996). Exogenous variables of the model were exercise habit and role belief. Endogenous variables were exercise-related affect, exercise self-efficacy, exercise barrier, exercise intention, and exercise behavior. The data were analyzed by SAS PC program and LISREL 8.12 program. Result: The degree of exercise behavior was low(mean 1.86, range 1~4). The overall fit of the model to the data was acceptable. Exercise habit, exercise self-efficacy and exercise-related affect were significant predictors of exercise intention and exercise behavior. Conclusion: This study shows the necessity of the program to increase the level of exercise participation of university students majoring in allied health science. The model constructed in this study is applicable to explain exercise behavior of university students majoring in allied health science, and suggests that we should focus on exercise habit, exercise self-efficacy and exercise-related affect to increase the level of exercise behavior of this group.

Purpose: This descriptive correlation study was done to identify the hardiness, coping behavior, and organizational commitment of general hospital employees and show how these variables affect increases in role performance and problem solving ability to have a positive influence on organizational harmony. Methods: A quantitative, descriptive research design was used with a sample of 368 employees working in general hospitals in M and C cities. A survey was used to collect the data. Results: The score for perception of hardiness of general hospital employees was 2.85, and coping behavior was 2.40, both out of a possible 4 points, and organizational commitment, 3.03 out of a possible 5 points. There were statistically significant positive correlations between hardiness and coping behavior (r=.33, p<.001), also between hardiness and organizational commitment (r=.51, p<.001), and also between coping behavior and organizational commitment (r=.22, p<.001). Conclusion: The results of the study indicate that hardiness, coping behavior, and organizational commitment in general hospital employees have positive correlations, and thus hospital administrators should explore ways of increase individual employee hardiness and coping behavior, and make efforts to harmonize their organizations by enhancing organizational commitment.

The purpose of this study was to analyze the role of perceived market influence, which is an important psychological factor influencing consumer behavior in the market, and explain how consumer beliefs related to the market can affect sustainable consumer behavior. First, this study found that gaps in perceived market influence were statistically significant for age and job. Second, environmental concern, organic food consumption (vegetables and meats), and purchase behavior of organic foods were found to be significantly different by degree of perceived market influence of consumers. The mean values were found to be high for the group having strong perceived market influence. This tendency suggests an association between higher perceived market influence consumers and more environmentally friendly consumer behavior. Lastly, this study used Structural Equation Modeling to analyze the effect of perceived market influence as a moderating variable and mediating variable on the relationship between environmental concerns and consumer behavior toward organic foods. The results show a mediating effect on perceived market influence, but a moderating effect could not be found. This result implies that perceived market influence might indirectly affect consumer behavior when transferring environmental concerns to consumer behavior toward organic foods.

This study examined the proper roles of dietitian and nurse-teacher in the weight control program (WCP) in schools and the effect of the WCP on subjects with respect to anthropometric measurements, nutrition knowledge, dietary attiude, and behavior changes. The program consisted of six sessions of nutrition education and frequent face-to-face nutrition counseling. Subjects were 22 obese children in the 4th and 5th grade who underwent counseling and 18 obese children in another school who served as a control group. After two months of WCP, obesity index such as .elative body weight (RBW, from 135.7 to 132.5), tricep skinfold thickness (TSFT, from 34.9 to 32.8 mm), and body fat content (from 32.0 to 29.8%) had decreased significantly in the experimental group, while the control group showed no significant differences in these indices. The reductions in obesity indices were maintained in the experimental group except for fat content (32.6%), which returned to its original value within six months. The control group significantly increased fat content in the same period (from 31.2% to 36.2%). Both groups decreased RBW, TSFT, and fat content while midarm circumference and waist/hip ratio remained the same after one year. Subjects' nutrition knowledge was improved with average test scores from 15.1 to 16.7 while nutrition attitude and behavior test scores remained unchanged suggesting that behavior modification may require more time than knowledge acquirement. These results suggest that proper nutrition counseling can initiate weight reduction. However, the maintenance of controlled weight requires changes in attitude and behavior which have not been achieved by the present WCP. The role of school dietitian for WCP in this study was limited to assisting the nurse-teacher in nutrition education. Expansion of dietitian's role in nutrition education and counseling is needed.

Purpose: The purposes of this study were to better understand types of health behavior in middle aged women in the Korean agricultural society, understand their nursing needs, and eventually present guidelines to develop proper nursing interventions. Method: Participants for this study were 16 middle aged women from farming communities, who lived in C county and were independent and without chronic ailments. In collection and analysis of data Strauss & Cortin's (1997) research processes and methods were used. The period of data collection was between April 2001 and February 2002. Result: The results of the study showed that the core category was the family-oriented process of $yangsaeng^{1)}$, and four types of health behaviors were observed; $momboyang^{2)}$ maintenance of health through daily life, managing mental health, and managing illness. Each type was perceived to differ from the other in the terms of health behavior priority which was largely affected by the cultural surrounding, for example, degree of attention to children's education and tendency to a traditional role for women. Conclusion: In conclusion, nurses need to understand various types of health behavior in middle aged women. The findings from this study can be applied to the development of Korean nursing interventions that are based on health behavior among middle aged women in the Korean agricultural society. These interventions can then. be based upon understanding of Korean culture rather than drawn only from Western concepts of health behavior.

This study determines the factors that contribute to the sense of self-identity for children from multicultural and rural families and provides a systematic understanding of individual self-identity. It also provides implications on how parents, teachers, and professionals can approach their role when instructing and rearing children of different sociocultural backgrounds. The subjects consist of the 310 children from multicultural families (Korean fathers and immigrant mothers) residing in South Korea and 280 children from rural families with similar conditions to those in multicultural families in North Jeolla Province South Korea. The sense of self-identity and maternal parenting behavior were perceived differently by children of multicultural and rural families, whose sense of self-identity was affected by school satisfaction and maternal parenting behavior.
