This study was conducted because of the investigator's concern for the high incidence and fatal nature of cancer in prime years of human life. The purpose of this study was to investigate risk factors on compilance for preventive health behavior of cancer. The data on which the analysis was based come from a survey of 828 married men & women, 40-59 years old. The instrument of the study were 'Health Belief Model' by Becker. The Data was analyzed using X--test, t-test, ANOVA, Pearson's Correlation Coefficient, Stepwise Multiple Regression. The followings were the result; 1. The examined group had a higher scores than the non-examined group in health belief variables. (p<0.001) 2. The higher level of health belief variables, the higher level of compliance for preventive health behavior is. (p<0.001) 3. The Stepwise Multiple Regression of compliance for preventive health behavior on the variables in the health belief model; Approximataly 65.5% of the variance of compliance for preventive health behavior was accounted for by health concern, susceptibility and barriers in combination. This meant that other factors seemed to influence preventive health behavior since the linear combination of variables failed to explain the remaining 34.5% of preventive health behavior of cancer. It tended to cost doubt on the usefulness of 5 variables in this model. Therefore further study to investigate the influential factors preventive health behavior of cancer is necessary.

A numerical procedure based on the finite element method for the nonlinear analysis of planar reinforced concrete frames is presented. Material nonlinearities such as cracking of concrete and yielding of steel are incorporated. This method is capable of providing accurate numerical solutions for the response of planar reinforced concrete frames failing primarily, in flexure throughout elastic, inelastic and ultimate load ranges. A numerical example is presented to demonstrate the validity and applicability of the present method. The results are compared with experimental results and the analytical results obtained by other investigator.

In this study a simple model is developed that predicts impact damage in a composite laminate using an analytical model. The model uses a non-linear approximation method (Rayleigh-Ritz) and the large deflection plate theory to predict the number of failed plies and damage area in a quasi-isotropic composite circular plate (axisymmetric problem) due to a point impact load at its centre. It is assumed that the deformation due to a static transverse load is similar to that occurred in a low velocity impact. It is found that the model, despite its simplicity, is in good agreement with FEM predictions and experimental data for the deflection of the composite plate and gives a good estimate of the number of failed plies due to fibre breakage. The predicted damage zone could be used with a fracture mechanics model developed by the second investigator and co-workers to calculate the compression after impact strength of such laminates. This approach could save significant running time when compared to FEM solutions.

Disposable marine product packaging materials such as wooden, Styrofoam, and corrugated cardboard boxes have a very low reuse rate, thus causing the logistics costs to rise and making it difficult to establish a unit load system for marine products. Disposable packing containers to be discarded are accompanied by resource and environmental issues home and abroad. Transportation vehicles for marine products have to return empty without loading different kinds of products after delivery due to the smell and properties of marine products, thus posing as an obstacle to logistics rationalization. In an effort to overcome those limitations, this study examined the stages of transportation including "producer-wholesale market in the producing area-commission merchant-wholesale market in the consumption area-commission merchant-quasi-wholesale market-consumer" and also analyzed the utilization and distribution of disposable packaging materials currently used in the circulation of marine products including wooden, Styrofoam, and corrugated cardboard boxes. Based on the analysis results, the investigator developed a logistics rationalization model capable of promoting semi-permanent reuse and lowering empty vehicle rate on return routes as an alternative to address environmental issues caused by disposable packaging materials, which have been an obstacle to the logistics rationalization of marine products, packaging costs in the process of repeating packing and unpacking at each stage of marine products circulation, and empty vehicle rates on return routes after marine products delivery.

Purpose: To examine the effect of a smoking prevention program on changing the knowledge and attitude toward smoking behavior of male middle school students. Method: A total of 69 male middle school students participated in this study. Each of them was assigned to either smoking prevention program (n=35) or to a control group (n=34). The intervention for the experiment group was developed by the investigator. The questionnaires for assessing knowledge and attitude were created by modifying scaled employed in previous studies. Result: 1) The experimental group with smoking prevention program showed higher scores in knowledge for smoking harmfulness in comparison with the control group (F=18.782, p=.000). 2) The experimental group with the smoking prevention program showed lower scores in attitude toward smoking behavior in comparison with the control group (F=17.483. p=.000). Conclusion: The results showed that the smoking prevention program was effective on improving knowledge and attitude toward smoking behavior in male middle school students. More studies on development of comprehensive smoking prevention programs for adolescents need to be conducted in the future.

Reconstruction analysis of traffic accident is done by analyzing diverse data such as the road, accident traces and damage on the automobile. Most data can be a variable in the process of analysis, and measurement error of the data occurs from the investigator, tool and the given environment. Therefore, accident analysis always has some risks of measurement uncertainty. This research quantify the uncertainty in traffic accident analysis by conducting repetitive measurement experiments for variables with high probability of uncertainly such as length (i.e. geometric structure of the road, tire marks) and coefficient of friction. This paper also suggests an analysis result for the uncertainly of photographic observation of automobile crush measurement. These statistical distributions can help determine appropriate ranges for the input data in order to estimate the accident reconstruction uncertainty.

Objectives: This pre-post quasi-experimental study was designed to investigate the effects of school based smoking prevention education on knowledge and attitude toward smoking, and the satisfaction of education among middle school students. Methods: The subjects included 94 middle school students in the experimental group. and 87 students in the control group. The educational content contained smoking refusal skills, which were taught through lectures and videos. Data collection was achieved using a self-reported questionnaire developed by the investigator. Data were analyzed with the SPSS 10.0 program including frequency, percentile, X2, paired t-test, and ANCOVA. Results: The results were as follows: 1. After the smoking prevention education, the smoking knowledge of the experimental group was significantly improved, whereas that of control group didn't change significantly. 2. There were no significant differences between pretest and post test attitude scores in both groups. 3. Refusal skill was the education content that provided the highest satisfaction for the subjects, and the degree of satisfaction was higher with video watching than with a lecture. Conclusion: Smoking prevention education for middle school students increased their level of smoking knowledge, but did not affect their attitudes toward smoking. Therefore, it is necessary to develop a more effective program, and to evaluate the effects of a long term education program with further studies.

Purpose: To identify bullying tendencies among elementary, middle, and high school students. Method: A descriptive study was conducted with 911 participating students. Data were collected using three, self-administered questionnaires that had been modified by the investigator. The data were analyzed by the SPSS Win 10.0 program using descriptive statistics, ANOVA. Result: The level of bullying was significantly different among elementary school, middle school and high school students. Middle school students were higher than elementary and high school students. In subtypes of bullying, language type was higher than alienation and physical damage types in elementary, middle and high school students. The methods to resolve a bullying situation are for the victim to 'speak to parents' in elementary school students, but 'bear alone' in middle school and highschool students. The answer to the question 'how many of your friends have been the victim of bullying' was 3-8 friends'. The reason for being a bully victim was 'because they pretend to be a superior man'. Conclusion: Although much research has been conducted in this area, further study among elementary, middle and high school students needs to be conducted. Furthermore, a variety of programs for preventing bullying among elementary, middle and highschool students should be developed.
