This study examined smoking behavior of Korean female college students by applying the Ajzen's Theory of Planned Behavior, and tried to uncover the factors influencing smoking behavior. The main findings are as follows: First, the attitude toward smoking behavior and the perceived behavioral control were statistically significant in predicting smoking intention. The smoking intention was also significant in predicting smoking behavior. Thus, in order to promote to stop smoking, smoking prevention education emphasizing to reduce smoking intention, to lower the positive attitude toward smoking behavior and to enhance the capacity for perceived behavioral control seems to be helpful. Second, the smoking intention influenced significantly over the smoking behavior in all situations. But the influences of the attitude toward smoking behavior, the subjective norms, and the perceived behavioral control over the smoking intention varied from not significant in one situation to significant in the other situation. Thus, different prevention programs according to the characteristics of individuals need to be developed. Third, in a path analysis, the grade and the degree of satisfaction with college life had the indirect influence, and the growth place had the direct influence over the attitude toward smoking behavior and smoking intention. Thus the smoking prevention program focusing on the students who are the first grade, less satisfied with college life, and growing up in small cities should be developed.

Background: The organizational citizenship behavior is generally known as the important factor relevant to the organizational effectiveness. This research examined the mediating effect of the organizational citizenship behavior of hospital employees on the organizational effectiveness. Methods: Data were collected from 1,112 employees located in city of Seoul, Kyunggi and Chungnam province through self-administered questionnaires. Collected data were analyzed using IBM SPSS ver. 20.0, frequency analysis, t-test, analysis of variance, regression analysis, and path analysis. The main findings of the study are as follows. Results: First, it was found that many characteristics variables of personality, job, and relationship together affected organizational citizenship behavior of hospital employees. Especially, the following variables of negative affectivity, desire for growth, job value, job significance, and job security were found to have significant effect on the organizational citizenship behavior of hospital employees. Second, the results of path analysis showed that, through the mediating effect of organizational citizenship behavior, personality variables of positive and negative affectivity, and desire for growth, job characteristics variables of job value, job significance, and job security, and relationship variables of organizational support and task interdependence, had significant total effects on the level of job satisfaction of hospital employees. Conclusion: As a result, the organizational citizenship behavior seems to have both direct and indirect effects on the organizational effectiveness of hospital employees. Based on above findings, some theoretical and practical implications were discussed.

Objective: The goal of this research is to develop new user behavior model using user motion analysis with microscopic perspective for attracting user's participation in interactive space. Background: The interactive space is 'human's place', which is made up of complex elements of digital virtual space and traditional analog and physical environment based on human-computer interaction system. Human behavior has changed in it at the same time. If the user couldn't make participation in interaction, the purpose of the system is not met, which reduces its effect. Therefore, we need to focus on interactive space that is potential future direction from a new point of view. Method: For this research, we would discuss and study fields of interactive space; (1) finding definition of interactive space and studying background of theory about it. (2) providing base of user behavior model with study of user's context that is to be user information and motion. (3) examining user motion, classify basic motion type and making user participation behavior model in phases. Results: Through this process, user's basic twenty motions which are systematized are taken as a standard for analysis of interaction process and participation in interactive space. Then, 'NK-$I^5$ (I Five)' model is developed for user participation types in interactive space. There are five phases of user participation behavior: Imperception, Interest, Involvement, Immersion, and Influence. In this analysis, three indicators which are time, motion types, and user relationship are found to be related to participation. Conclusion: The capabilities and limitation of this research is discussed to attract user participation. This paper focuses especially on contribution of design to lead user's participation in interactive system and expectation to help adapt to user centered design of various interactive space with new aspect of user behavior research. Application: The results of the 'NK-$I^5$ (I Five)' model might help to realize successful interactive space based on user centered design.

The purpose of this study is to verify the relationships among innovative behavior, turnover intention, and job security. An additional purpose was to examine partial mediating effects on psychological ownership. The baseline of analyzing those relationships in this study is that the role of psychological ownership will be a mediator between job security and turnover intention as well as innovative behavior in the organization. To accomplish these purposes, a model was built among job security as predictor variable, the psychological ownership as mediating variable and turnover intention, and innovative behavior as criteria variables based on the studies conducted in the various areas. The 248 questionnaires surveyed from the area of DaeGu and Kyungbuk were used in the statistical analyses. The detail statistical techniques are such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, and multi regression analysis. The results of the study show that job security had positively significant effect on turnover intention and innovative behavior. In addition, only the psychological ownership of organization-level thinking have partial mediating effects between job security and innovative behavior also job security and turnover intention. The results may indicate that the psychological ownership of organization-level thinking be a key factor to alleviate the turnover intention of employees and to encourage the innovative behavior during their works for the small-medium size companies showing the unstable job security.

Objectives: This study was conducted to develop and validate Eating Behaviors Test form (EBT) for infants and young children, including eating behaviors of their parents and parental feeding practices. Methods: Draft version of EBT form was developed after a pretest on 83 mothers. It was consisted of 42 questions including 3 components; eating behavior of children, eating behavior of parents, and parental feeding practices. Using these questionnaires, the first survey was conducted on 320 infants and children, 1 to 6 year old, for exploratory factor analysis, and the second survey was collected on 731 infants and children for confirmatory factor analysis. Results: Exploratory factor analysis on 42 questions of EBT form resulted in 3 factor model for children's eating behavior, 3 factor model for parents' eating behavior, and 1 factor model for parental feeding practices. Three factors for children's eating behavior could be explained as follows; factor 1, pickiness (reliability ${\alpha}=0.89$; explanation of variance=27.79), factor 2, over activity (${\alpha}=0.80$, explanation of variance=16.51), and factor 3, irregularity (${\alpha}=0.59$, explanation of variance=10.01). Three factors for mother's eating behavior could be explained as follows; factor 1,irregularities (${\alpha}=0.73$, explanation of variance=21.73), factor 2, pickiness (${\alpha}=0.65$, explanation of variance= 20.16), and factor 3, permissiveness (${\alpha}=0.60$, explanation of variance=19.13). Confirmatory factor analysis confirmed an acceptance fit for these models. Internal consistencies for these factors were above 0.6. Conclusions: Our results indicated that EBT form is a valid tool to measure comprehensive eating and feeding behaviors for infants and young children.

Finite element analysis(FEA) is the most popular numerical method to simulate plasticity-induced fatigue crack closure and can predict fatigue crack closure behavior. Finite element analysis under plane stress state using 4-node isoparametric elements is performed to investigate the detailed closure behavior of fatigue cracks and the numerical results are compared with experimental results. The mesh of constant size elements on the crack surface can not correctly predict the opening level for fatigue crack as shown in the previous works. The crack opening behavior for the size mesh with a linear change shows almost flat stress level after a crack tip has passed by the monotonic plastic zone. The prediction of crack opening level presents a good agreement with published experimental data regardless of stress ratios, which are using the mesh of the elements that are in proportion to the reversed plastic zone size considering the opening stress intensity factors. Numerical interpolation results of finite element analysis can precisely predict the crack opening level. This method shows a good agreement with the experimental data regardless of the stress ratios and kinds of materials.
