The future social makes an multipule effort to secure native competition. It is very difficult to foresee the length and deepest on the future social coming soon than human beings has experienced until now. The future social will be adopt a positive attitude on lifelong education, also, because It will be rapidly change. Like this foundation knowledge economic will be secure which a knowledge is high value and build up a fortune. Now, new sight for education is necessary definitely to a person. In the future, labor viability is utterly dependent on what the lifelong educations ability is.

This study investigated the differences in college students' attitudes towards, and knowledge of contraceptives. Gender, age group and place of residence were examined to identify variables related to contraceptive use. A total of 388 responses were obtained from college students. The results are as follows: Firstly, significant differences were found in degree of contraceptive knowledge between genders, age groups, and residence types. There was also a significant interaction effect between gender and age. Secondly, there were significant differences of attitudes towards contraception in gender and age and there was also significant interaction effect between residence type and age. Thirdly, college students' contraceptive use could be successfully predicted by gender and attitude towards contraception. Male students who had positive attitudes towards contraception were more likely to use contraceptives. This suggests attitudes towards contraception should be considered when developing contraceptive programs.

BACKGROUND/OBJECTIVES: This research was conducted to compare lecture- and experience-based methods of nutritional education as well as provide fundamental data for developing an effective nutritional education program in elementary schools. SUBJECTS/METHODS: A total of 110 students in three elementary schools in Jeollanam-do were recruited and randomly distributed in lecture- and experience-based groups. The effects of education on students' dietary knowledge, dietary behaviors, and dietary habits were analyzed using a pre/post-test. RESULTS: Lecture- and experience-based methods did not significantly alter total scores for dietary knowledge in any group, although lecture-based method led to improvement for some detailed questions. In the experience-based group, subjects showed significant alteration of dietary behaviors, whereas lecture-based method showed alteration of dietary habits. CONCLUSIONS: These outcomes suggest that lecture- and experience-based methods led to differential improvement of students' dietary habits, behaviors, and knowledge. To obtain better nutritional education results, both lectures and experiential activities need to be considered.

Process planning (selection and ordering of processes) and material selection for product manufacturing are two key things determined before taking full-scale manufacturing. Knowledge on product design. material characteristics, processes, time and cost all-together are mutually related and should be considered concurrently. Due to the complexity of problem, human experts have got only one of the feasilbe solutions with their field knowledge and experiences. We propose a hierarchical expert system framework of knowledge representation and reasoning in order to overcome the complexity. Manufacturing processes have inherently hierarchical relationships, from top level processes to bottom level operation processes. Process plan of one level is posted in process blackboard and used for lower level process planning. Process information on blackboard is also used to adjust the process plan in order to resolve the dead-end or inconsistency situation during reasoning. Decision variables for process, material, tool, time and cost are represented as object frames, and their relationships are represented as constraints and rules. Constraints are for relationship among variables such as compatibility, numerical inequality etc. Rules are for causal relationships among variables to reflect human expert\`s knowledge such as process precedence. CRSP(Constraint and Rule Satisfaction Problem) approach is adopted in order to obtain solution to satisfy both constraints and rules. The trade-off procedure gives user chances to see the impact of change of important variables such as material, cost, time and helps to determine the preferred solution. We developed the prototype system using visual C++ MFC, UNIK, and UNlK-CRSP on PC.

The purpose of this study was to investigate the university student's dietary behaviors, lifestyle and nutrition knowledge. The survey were composed of 81 male and 64 female students at W University in Daejeon. Results of survey shown that BMIs of male students was 23.9 which is higher significant at p<0.001 than female students was 20.8. In lifestyle, dietary habit patterns of female students showed higher significant in meal if under stress and snack intake at p<0.05. In terms of dining-out, both female and male students like Korean food. However, female students like Western food and flour-based food than their male counterpart. While male liked Chinese and Japanese foods at p<0.05. A siginificant higher proportion of male students smoked (p<0.001); drink (p<0.01) and exercised (p<0.05) than their female counterpart. In terms of nutrition knowledge, males have higher scores (out of a possible 15 points) than female scores (p<0.01). The results of this study suggests that nutrition education can motivate and improve dietary management for dietary compliance. Therefore, a proper planned nutrition education programs for university students is an efficient and effective education method.

Industrial processes are normally operated by skilled humans who have the cumulative and logical information about the system. Fuzzy control has been investigated for many application. Intelligent control approaches based on fuzzy logic have a chance to include human thinking. This paper represents modeling approach based upon operators knowledge without mathematical model of the system and optimize the controller. The experimented system is constructed for sending a ball to the goal position using wind of two DC motors in the predefined path. A vision camera to mimic human eyes detects the ball position. The system used in this experiment could be hardly modeled by mathematical methods and ould not be easily controlled by conventional manners. The controller is designed based on the input-output data and experimental knowledge obtained by trials, and optimized under the predefined performance criterion. And this paper shows the data adaptation for changeable operating condition. When the system is driven in the abnormal condition with unconsidered noise, the new optimal operating parameters could be defined by adjusting membership functions. Thus, this technique could be applied in industrial fields.
