Tessellations are the pattern of iterations of geometric transformation. We can find them in the works of Escher, the famous Dutch artist. Also, We can find the beauty of tessellations in traditional Korean house doors, old Korean architecture, palace walls, and so forth. In this article, the figures of patterns we present are a pig, a frog, Tchiucheonwhang (the mascot of Korean football supporters), and figures by Escher, using the computer geometric program, GSP (Geometer's Sketchpad). We wanted to investigate the gender differences on students' achievement and disposition toward mathematics in constructing tessellations. The results indicated that if students were supported with well prepared instructional materials which helped students make their own figures, female students in particular would be more interested in learning geometric transformation.

Because sexual awareness is changing, I have tried to classify university students' attitudes toward sex. This study examined male and female university students and used a Q-method to measure these attitudes. Out of a total of 202, 33 statements were abstracted, and a P-sample of 1-7 parties consisting of 26 persons were studied. I Q-sorted the statements with a standard of 9 points for normal distribution and analyzed the data by means of a Principal Component Analysis with a Quan PC Program. According to the result of this research, university students' attitudes toward sex are divided into three types. Type 1 are called open-minded open: They may have a surgical abortion in case of an unexpected pregnancy and sexual intercourse occurs when a man and woman feel love for each other. They don't see sexual intercourse as a means reproduction nor virginal purity as unconditional. It is remarkable that these students regard sexual intercourse as a natural thing and sex as a basic desire of human beings. In short, they show an open-minded attitude toward sex. Type 2 are supporters of virginal purity; They regard virginal purity with great importance. They insist that both man and woman should be chaste but that sexual intercourse before marriage is unfavorable only to the woman. They do not believe in sexual intercourse without love and emphasize purity in sex education. Differen from type 1, they are very negative about surgical abortion. Type 3 experss love through sex. They belive that sexual intercourse makes a couple happy and a way to express their affection for each other. In other words, the relationship between man and woman is improved through sexual intercourse. They do not think of sexual intercourse in terms of childbirth.

The engineering knowledge and technology is core driving forces of continuous growth in knowledge based society. Companies, the government, and universities are the subjects of an innovation and the cooperation between them is very important. Nowadays, the main purpose of industry-university cooperation moves to train experts and develop a new product. A shift of the paradigm came from the change of recognition that the final consumers of the program are companies and the universities are supporters of the program. In this paper, we investigate the purpose, participation and satisfaction of companies to industry-academy technology cooperation through empirical studies. The need to expert training, product development and process development makes companies participate industry-academy technology cooperation and companies have different purpose of participation by the business type. Companies often feel that expert training, subsidiary purpose of industry-academy technology cooperation, is more important than product development or process development. This result is caused by the real world environment of small and mid-size companies, lacking of technology experts. The participation of companies to each technology cooperation program (technology transfer, joint technology development, consigned technology development, technology consulting, co-op. lab.) is also different by business type. The companies' satisfaction with the purpose of process development is relatively higher than that with the purpose of product development and companies show also different satisfaction value by business type and participating program. The results of this study can give a contribution to the design of demand oriented industry-academy technology cooperation model.

This study examined understanding and attitude of sustainable development(SD) of 38 college students in a nuclear power plant construction after education for sustainable development(ESD) through panel discussion. The results were as follows: First, after lesson 66% of students were expected that SD is possible if scientific technology is developed and a frugal life for the protection of environment is carried out. However, the remaining students regarded SD as an ideal concept, because they thought it is not possible to pursue environmental sustainability and socio-economic development simultaneously. Second, students' opinions in the evaluation of constructing a nuclear power plant in three aspects(environment, society and economy) before and after panel discussion were changed as follows; 1) After panel discussion, the objectors increased to 21% in economic evaluation, while the supporters increased to 11% in environmental evaluation. 2) Students majoring in engineering or natural sciences changed their opinions to agree in environmental evaluation because they considered a nuclear power plant safe and eco-energy. However students majoring in social science/business or liberal arts/arts changed their opinions to disagree in economic evaluation because they considered a nuclear power plant as high-cost energy when assessing danger-accidents cost, public consensus cost, operation and maintenance cost, and waste disposal cost. 3) This change of decision-making in students majoring in social science/business or liberal arts/arts after panel discussion was statistically significant(p<0.05). Implications of panel discussion as a teaching and learning method in ESD are also discussed.

This study was carried out to investigate the experiences of breast milk feeding information and education, breast milk feeding knowledge and attitude and needs for breast milk feeding nutrition education of high school students to encourage breast milk feeding. The subjects were 565 (male: 250, female: 315) high school students from first to third grade. The results obtained were as follows: In this survey, only 30.0% of subjects experienced breast milk feeding information and only 6.1% of subjects had breast milk feeding education. And the subjects showed the average scores of knowledge of breast milk feeding were 0.29 points of 1 point. Subjects knew well about ingredients of breast milk but they didn't know well about the physiology and method of breast milk feeding and benefits of breast milk feeding for mothers. The average scores of attitude of breast milk feeding were 3.03 points of 4 points, showed slight positive attitudes of breast milk feeding, but they had negative attitudes of emotional and practical aspects. The future plan of feeding practices was breast milk feeding 35.9% and 60.0% of formula milk feeding. A concern was that the students showed high ratio of formula milk feeding plan and they decided by incorrect knowledge of breast milk feeding. The 33.5% of students answered high school students will need breast milk feeding nutrition education, and they thought hospital faculties were the proper educators of breast milk feeding education, but dietitians were recomended as educators because of easy access at school and good knowledge of life-cycle nutrition. Therefore, to encourage breast milk feeding by mothers and supporters of breast milk feeding, breast milk feeding nutrition education is needed urgently among high school male and female students. And nutrition education programs will have to contain benefits of breast milk for babies and mothers and physiology and practical methods of breast milk feeding to improve emotional and practical attitudes for breast milk feeding. Nationwide campaign to promote breast milk feeding at public areas will be needed.

This study was intended to enlighten two-faced desires of the Bauhaus, revealing that it is closely related with the child education rooted in Frobel. The Bauhaus declared to disconnect with the traditional education standing for Academies and asked students to go bad to such 'innocence' as children had. The faculty of Bauhaus tried to understand of the essence of the world through primary geometrical forms as 'purity' without any inessential things as $Fr{\ddot{o}}bel$ did. Their attempts not to admit any nonessential things, however, and dinging to purity was rather a sort of neurosis. The modernism is not different from the child art hiding sadistic and dictatorial elements behind the myth of 'innocence'. Considering the child education was born and grown with nutrition from the bourgeois development, it was not compatible with democratic ideals of the Bauhaus. While the new types of schools for children provided an excellent preparation for the Bauhaus to initiate a new design education, people of the Bauhaus were going toward a different direction from aspiration of the bourgeois, strong supporters of the new schools.

This study has been performed to explore verbal and behavioral expression of sexual desires among male elderly residents who have been living in long tenn care facilities. There are three topics covered in this study; first, in what situations and how seriously do care workers encounter expression of sexual desires of the elderly residents? Second, what kind of negative consequences do they believe those sexual behaviors will lead to? Third, how can we implement defensive measures against the sexual behaviors? In this study, twenty three care workers working full time in five retirement and care facilities were asked about their experience and perception of the above study agendas, and answers of the qualitative interview were drawn as follow; first, the elderly residents apparently show a variety of sexual harassment and provoking behaviors such as sticking to specific women, physically touching and attacking, and induce obscenely activities against female residents, care workers, and volunteer visitors. Second, their sexual behaviors are often influenced by their isolated and abandoned emotionality as well as living situation in rural areas. Third, their sexual behaviors often critically affect care work plan and facility managements by severely discouraging female care givers and community supporters. Therefore in this study, suggestions and defensive measures were made as follows: first, education and counselling programs toward female workers and volunteers need to be developed, and the programs should cover psychological and behavioral mechanism of sexuality in later life. Second, self control plans need to be empowered toward the elderly residents; in the plans, the elderly residents shall be encouraged to evaluate primary cause and proper solutions of sexual behaviors of their peering residents. Third, combination of healthy housing and care facilities for frail elderly need to be integrated in a neighboring location, so that when residents and workers encounter extreme episodes of sexuality of healthy residents in a housing facility, the problematic sexual residents are partially transferred into a neighboring care facility and thereafter other residents and cafe givers are relieved from stressful contacts with the extremely sexual residents.

Increased multi-cultural families over the recent decade have led to more studies on the current situations and problems they face. Fathers in multi-cultural families are supporters who can help their migrant wives adapt their new surroundings; however, it is difficult to find studies on them as their roles as fathers in multi-cultural families have been overlooked. This study develops educational programs for fathers in multi-cultural families and analyzes the effect of the educational programs. The educational program development for fathers in multi-cultural families was based on consideration of related articles, studies, and reports. The effect analysis for the educational program for fathers in multi-cultural families was performed through the investigation of 'self-esteem' and 'parent self-confidence' about educated fathers in multi-cultural families. The educational program for fathers in multi-cultural families was composed of 5 themes which can improve their self-esteem, understand the father's role and function, learn the skills of playing and conversation with their children and express the father's thoughts for his own family using positive methods. We educated 12 fathers in multi-cultural families through the development of the program over 5 weeks to verify the effect of educational programs for fathers in multi-cultural families. The results showed the following : The level of father's self-esteem in multi-cultural family increased 124% and the level of parent self-confidence increased 141%. In conclusion, the educational effect for fathers in multi-cultural family exists and their desire for a successful multi-cultural family increased through the educational programs.

The study is aimed to investigate the current status of ESD(Education for Sustainable Development) programs in private sector(businesses) carried out in Korea since UN DESD was launched in 2005, For this purpose we conducted a questionnaire survey and case studies on those companies who have supposedly pursued sustainability management Results of questionnaire surveys showed that those in charge of writing sustainability reports in companies had an extremely high understanding of SO, but were not well aware of ESD. These businesses started to pursue sustainable management due to global trends and decisions of CEOs, and most of them had divisions that took charge of or are responsible for sustainable management Sustainability issues that they mainly dealt with were corporate social responsibility, energy and climate change, but other issues were being covered, too. Internal stakeholders got involved in projects related to sustainability from the planning stage. Learning on sustainable management was primarily made through information delivery, and education programs were usually conducted for staff members and executives. Those who cooperated on their sustainable development projects were mostly local communities, universities, etc. They had few ESD programs that they directly developed and carried out, and few cases of ESD-related cooperation; and in those few cases, their partners were often elementary/middle/high schools and universities. Results of ESD case studies and questionnaire surveys showed that businesses dealt with various issues of sustainable development in addition to corporate social responsibility and diversified education programs were carried out inside these companies, Business themselves, therefore, need to be considered and researched in further detail as important targets of ESD as well as supporters or cooperation partners on ESD programme.

In recent years, as changing the habit of eating, the pathology in the colon grows up annually. The colonoscopy is generalized, but if requires much time to acquire a dexterous skill to perform an operation and the procedure is painful to the patient. biomedical and robotic researchers are developing a locomotive colonoscope that can travel safe1y in colon. In this paper, we propose a new actuator and concept of semi-autonomous colonoscope. The micro robot comprises camera and LED for diagnosis, steer- ing system to pass through the loop, pneumatic actuator and bow-shaped flexible supporters to control a contact force and to pass over haustral folds in colon. For locomotion of semi-autonomous colonoscope, we suggest an actuator that is based on impact force between a cylinder and a piston. In order to validate the concept and the performance of the actuator, we carried out the simulation of moving characteristics and the preliminary experiments in rigid pipes and on the colon of pig.
