The study surveyed 1,127 mothers whose children aged 3 to 5 went to 25 randomly selected kindergartens, which were located in Busan Metropolitan City and the adjacent Gimhae City, and analyzed the preventive health behaviors on their children and the condition of home health education on their children. As the compulsory kindergarten education will e to be implemented within 4 years, this study aimed to draw up the rudimentary material for health education at kindergartens. The study results are summed up as follows: 1. Mothers' awareness of health-related attitude and behavioral level for their children at kindergarten: 1) The general health condition of the children, which mothers are aware of, was that they were healthy on the whole. As their children becomes older, the income level of the parents is lower, and mothers have lower level of educational standard, the health condition of the children was found a little lower. 2) In terms of mothers' recognition of the practice level of preventive health behaviors, the items such as going to bed regularly, washing hands and feet well, and having meals regularly were high in the practice level, while exercise and tooth-brushing were not practiced well. 2. The condition of mothers' health education of their children: 1) It was found that washing hands and feet, restriction of overeating and preference for specific kinds of food, guidance on regular sleep and regular meal were practiced well among items of home health education targeting kindergarten children. 2) Mothers have obtained information on family health from printed matter such as newspaper or magazine rather than the visual media. 3) From the cross analysis of mothers' health education on children and children's health behaviors, as the standard of education of mothers was higher, so was the level of preventive health behaviors of children. 3. From the result of multi regression analysis of the factors influencing the preventive hygiene of kindergarten children, it was found that as the home health education level was higher, so was the health behavior of children. On the other hand, as the mothers were older, the health behavior of children became lower.

While the demand for robots in the manufacturing industry has dramatically increased, the industrial robots' functionality is mainly determined by the effector attached to the end of their arms. They need a flexible gripping system that can act as a human hand and easily grasp a variety of objects, which requires resilient sensors. This study clarifies the electrical output characteristics of elastic tactile sensors according to contact terminals because the output characteristics of the tactile sensors vary greatly, depending on the contact material and the method of contact with the conductive wire. Our research considers the Three Roll Mill and Paste Mixer as the dispersion medium, and a nickel- and gold-plated brass electrode as the contact terminal.

Microelectronic product consumers may already be expecting another paradigm shift with smarter phones over smart phones, but the current status of microelectronic manufacturing engineering education (MMEE) in universities hardly makes up the pace for such a fast moving technology paradigm shift. The purpose of MMEE is to educate four-year university graduates to work in the microelectronics industry with up-to-date knowledge and self-motivation. In this paper, we present a comprehensive curriculum for a four-year university degree program in the area of microelectronics manufacturing. Three hands-on experienced-based courses are proposed, along with a methodology for undergraduate students to acquire hands-on experience, towards integrated circuits (ICs) design, fabrication and packaging, are presented in consideration of manufacturing engineering education. Semiconductor device and circuit design course for junior level is designed to cover how designed circuits progress to micro-fabrication by practicing full customization of the layout of digital circuits. Hands-on experienced-based semiconductor fabrication courses are composed to enhance students’ motivation to participate in self-motivated semiconductor fab activities by performing a series of collaborations. Finally, the Microelectronics Packaging course provides greater possibilities of mastered skillsets in the area of microelectronics manufacturing with the fabrication of printed circuit boards (PCBs) and board level assembly for microprocessor applications. The evaluation of the presented comprehensive curriculum was performed with a students’ survey. All the students responded with “Strongly Agree” or “Agree” for the manufacturing related courses. Through the development and application of the presented curriculum for the past six years, we are convinced that students’ confidence in obtaining their desired jobs or choosing higher degrees in the area of microelectronics manufacturing was increased. We confirmed that the hypothesis on the inclusion of handson experience-based courses for MMEE is beneficial to enhancing the motivation for learning.

Objectives: Unprotected leisure time exposure to ultraviolet radiation from the sun or artificial tanning beds is the most important environmental risk factor for melanoma, a malignant skin cancer with increasing incidences over the past decades. The aim of the present study was to assess the impact of skin health information provided by several sources and different publishing issues on knowledge, risk perception, and sun protective behavior of sunbathers. Methods: A cross-sectional questionnaire survey was conducted among Austrian residents (n=563) spending leisure time outdoors in August 2010. Results: Print media, television, and family were perceived as the most relevant sources of information on skin health, whereas the source physician was only ranked as fourth important source. Compared to other sources, information provided by doctors positively influenced participants' knowledge on skin risk and sun protective behavior resulting in higher scores in the knowledge test (p=0.009), higher risk perception (p<0.001), and more sun protection (p<0.001). Regarding gender differences, internet was more often used by males as health information source, whereas females were more familiar with printed information material in general. Conclusions: The results of this survey put emphasis on the demand for information provided by medical professionals in order to attain effective, long-lasting promotion of photoprotective habits.

Materials that can be used for 3D printing have been developed in terms of phase and functionality. Materials should also be easily printed with high accuracy. In recent years, the concept of 4D printing has been extended to materials whose physical properties such as shape or volume can change depending on the environment. Typically, such high-performance 3D printing materials include bio-inks and inks for sensors. This study deals with the optimization of the manufacturing method to improve the functional properties of the pressure sensitive material, which can be used as a sensor based on change of the resistance according to the pressure. Specifically, the number of milling for dispersion, the ratio of hardener for controlling elasticity, and the content of MWCNTs were optimized. As a result, a method of manufacturing a highly sensitive pressure-sensitive ink capable of use in 3D printing was introduced.

The major purpose of this study was to develop the nutrition education contents and material through the basic data from the service provider and the consumer. And also, to find out the differences of attitude and needs between the service provider (SP breastfeeding specialist), present consumer (PC, pregnant or lactating women) and future consumer (FC, college women). There were types of questionnaires, which consisted of needs and attitudes toward child and maternal nutrition, as well as the personal characteristics of the study subjects. The subjects consisted of 113 breastfeeding specialists who served at medical related institutions, 197 pregnant or lactating women and 309 college women. The self-administered questionnaires from subjects were collected from October to November 2005 in Seoul and Kyunggi Province. The data was analysed by SPSS Win 12.0, ANOVA and Kruskal-Wallis test. The results of this study were as following: 1) The most Important determining factors on breastfeeding was 'medical specialist's support' (3.51) and the next one was 'knowledge of maternity care practice' (3.39). And the importance score of determinating factors on breastfeeding was significantly different between each group (p < 0.001). The groups of consumer (3.50 at PC and 3.59 at FC) considered the service provider (3.32) more important. The service providers considered a more effective determining factor to be 'husband and family support' and 'peer support' than the others (p <0.001). 2) To compare the effective factors of breastfeeding practices between the three groups, the service providers were more significantly considered than the otters such as 'attendance of intervention program' (p < 0.001). But the PC group considered the most effective factors wis 'mother's job after delivery'. 3) The self-evaluated score of the breastfeeding knowledge was the most high in SP; the score was significantly different between groups. The knowledge score of nutritional aspects in human milk was most highly evaluated. But maternity care practice and public acceptance marked the lower evaluation score than other issues. 4) The desirable types of educational material was mass media, and the next was printed matter such as booklets. Two kinds if consumers preferred DVD or VCR tapes than and the service provider group (p < 0.001). 5) The priority contents of nutrition service PC group wanted the information about infant care more than maternal care (p < 0.05), but FC group's priority was significantly different compared with PC group (p < 0.001). The priority of SP group pointed out the information of practical child care methods. The results showed the needs of nutrition service, education channels, and perception toward effective factors on consumer behavior changes were significantly different between each group. Thus the result of this study may suggest that consumer oriented nutrition service programs must be developed.

The purpose of this study is to understand the current status of high school students' exposure to pornographic materials as well as to provide basic data to develop sex education programs. This study was conducted through a self-administered questionnaire survey of 774 students of six high schools in Seoul, three boys' and three girls' respectively, from August 22 to August 25, 2000. This study shows that high school students' exposure to pornographic materials such as CD-ROMs, internet, video tapes and adult movies has become very serious. The results of this study are as follows. 1. Among the students surveyed, $23.5\%$ of them currently has opposite-sex friends, while $42.2\%$ used to have and $34.2\%$ has never had opposite-sex friends. 2. $55.3\%$ of the students pick up their sexual knowledge from their friends, followed by mass media $(47.5\%),\;school (21.1\%),\;adult\; magazines (17.1\%)\;, internet (14.1\%)$, pornography visual $materials (11.5\%),\; sexual\; books (3.6\%)$ and pornography printed $materials (2.4\%).$ 3. Regarding the frequency of sexual education taken in school, $54.2\%$ of the students answered 'often', while $37.6\%$ answered 'almost none', 'several times' $(4.4\%)$, 'never' $(2.9\%)$ and 'frequently' $(0.9\%)$, respectively. Regarding sexual education at home, $42.2\%$ answered 'almost none', followed by 'never' $(36.3\%)$, 'often' $(16.3\%)$, 'several times' $(3.3\%)$ and 'frequently' $(1.8\%)$, respectively. 4. $68.2\%$ of the students have been exposed to adult movies, followed by pornography videos $(60.1\%)$, internet chatting $(50.2\%)$ and pornography computer diskettes $(38.0\%)$. 5. The degree of exposure to pornographic materials of boy students is much higher than that of girl students. 6. It appears that there is an interrelation between the kind of schools and the degree of the students' exposure to pornographic materials. 7. The higher the students' grade is. the more they have been exposed to pornographic materials. 8. It shows that there is an interrelation between the students' academic performance and the degree of their exposure to pornographic materials. 9. There is also an interrelation between the amount of students' pocket money and the degree of their exposure to pornographic materials. 10. There is an interrelation between the degree of their adaptation to school life and the degree of their exposure to pornographic materials. 11. It appears that there is an interrelation between their parents' relations with them and the degree of the students' exposure to pornographic materials. 12. There is a significant difference in the degree of their exposure to pornographic materials in accordance with their residential area. 13. There is also a significant difference in the degree of their exposure to pornographic materials in accordance with the average income of their families. 14. There is also a significant difference in the degree of their exposure to pornographic materials in accordance with the mean sexual education at home.
