This study explored the eating attitudes, dieting habits, weight perception and exercise behavior of Korean women. Self-reported questionnaires were administered to 724 Korean college students. Compared to males, female students felt themselves overweight and dissatisfied with their body and desired to lose weight although both groups were within the range of the national standard. Female students dieted more, while males exercised more. Eighteen percent of females showed disturbed eating behavior. The score for disturbed eating behavior was highly related to weight perception in the female students. These results suggest that Korean college women have a high prevalence of eating disturbances without having actual weight problems. A majority of the women desired to lose weight which may be due to the misperception of their body weight and fatness. However, they did not adopt appropriate strategies such as doing regular exercise to reduce their body weight.

This study proposed a method to apply certain fuzzy-related Quality control concepts to design customer-oriented products considering user requirements and information starting with the product development stage. This approach showed how to define the importance level of design elements and how to Quantify complex subjective perception of products using the fuzzy linguistic rating method and quality function deployment concepts. Using this approach, various customer requirements could be interpreted and reflected on the early design phase of a new product. To validate the proposed method, an experiment was conducted for designing the shape of the beeper using 14 subjects and 10 commercial beeper products. Front area, width/length ratio, thickness, curve variance, weight, and display area were selected as design elements of the beeper. The results showed that among design elements, front area and weight are significantly related with the subjective perception of the products. Consequently, this study indicates that customer decision on product selection could be made by quantification of user perception for beeper products.

This study investigates the production and perception of Vietnamese tones by Japanese, Lao, and Taiwanese second language (L2) learners [n=30], comparing their performance in an Imitation task to that of Identification and Read-Aloud tasks. The results show that the Imitation task is generally easier for L2 speakers than the Identification and Read-Aloud tasks, suggesting that imitation is performed without some of the skills required by the other two tasks. It is also found that Lao and Taiwanese speakers outperform Japanese speakers, suggesting that prior experience with one tone language facilitates the acquisition of tone in another language. The result on speakers' tonal range show that L2 leaners have significantly narrower tonal F0 range than control Vietnamese speakers [n=11]. The results of error pattern analysis and tonal transcription also suggest that non-modal voice (glottal stop and creakiness) and contour tones (bidirectional fall-rise) are more difficult for L2 learners than modal voice tones (e.g., unidirectional contours: rising, falling, and level).

The purpose of this study is to investigate the changes of sensory and visual perception of children with intellectual disabilities by conducting psychomotorik (psychomotor activity) in the forest and indoor treatment rooms. Accordingly, this study divided 18 children with intellectual disabilities living in the facility for persons with disabilities located in Seoul into three groups: the experimental group participating in psychomotorik in the forest, the comparative group participating in psychomotorik in the treatment room, and the control group without any treatment at all. The program was conducted for 32 weeks, 4 hours a month. The results showed that psychomotorik promoted the sensory and visual development of children with disabilities. Psychomotorik in the forest showed significant effects on touch and activity level, form constancy and eye-hand coordination. Psychomotorik in the treatment room showed significant improvement in figure-ground with reduced motion. This suggests that psychomotorik in the forest as well as indoors is a positive factor for sensory adaptation reaction and visual development of children with intellectual disabilities.

This paper presents the theoretical development of a complete navigation problem of a nonholonomic mobile robot by using ultrasonic sensors. To solve this problem, a new method to computer a fuzzy perception of the environment is presented, dealing with the uncertainties and imprecision from the sensory system and taking into account nonholonomic constranits of the robot. Fuzzy perception, fuzzy controller are applied, both in the design of each reactive behavior and solving the problem of behavior combination, to implement a fuzzy behavior-based control architecture. The performance of the proposed obstacle avoidance robot controller in order to determine the exact dynamic system modeling system that uncertainty is difficult for nomadic controlled robot direction angle by ultrasonic sensors throughout controlled performance tests. In additionally, this study is an in different ways than the self-driving simulator in the development of ultrasonci sensors and unmanned remote control techniques used by the self-driving robot controlled driving through an unmanned remote controlled unmanned realize the performance of factory antomation.

Purpose: This study was conducted to test the effect of a scenario based hand hygiene education program on hand hygiene knowledge, hand hygiene perception, hand hygiene compliance and hand hygiene method in nursing students. Methods: A non-equivalent control group, non-synchronized quasi-experimental design was used. Forty five nursing students participated in the study with 22 in the experimental group and 23 in the control group. Data were analyzed using descriptive statistics, ${\chi}^2-test$, t-test, and repeated measures of ANOVA. Results: There were significant increases in hand hygiene knowledge (t=-4.28, p<.001) and accuracy of the hand hygiene method by week (F=7.33, p<.001). However, hand hygiene perception (t=-1.67, p=.102) and hand hygiene compliance rate (F=7.33, p=.405) were not significantly changed. Conclusion: The effects of the scenario based hand hygiene education program provided in this study were excellent, compared to the other hand hygiene education programs. Moreover, as a result of investigating the education effects through direct observation for 4 weeks, appropriate feedback was offered in the third week, and it was found that maintaining the effect was necessary. However, the current status of hand hygiene compliance and accuracy of methods for ensuring hand hygiene need to be studied further.

Purpose: The purpose of this study was to identify the level of body perception, obesity, and factors associated with stages of exercise and dietary habits change in university students. Methods: A descriptive design was used. Data were collected from 279 university students using structured questionnaires. Results: The body perception was significantly associated with self rated health (F=27.89. p<.001), weight satisfaction (F=137.74. p<.001) and weight control interest (F=39.19. p<.001). The BMI was significantly associated with weight satisfaction (F=34.08. p<.001) and weight control interest (F=19.59. p=.003). But the body perception and BMI were not significantly associated with depression (F=2.17, p=.073, F=0.86. p=.462), the change of exercise (F=25.91. p=.055, F=20.34. p=.061), and dietary habits (F=12.96. p=.677, F=11.29. p=.505). The related factors affecting the change of exercise behavior were counter conditioning, self efficacy, eating behavior, and helping relationship, including 30.4% R-square. The related factor affecting the change of dietary habit was only eating behavior, including 20.0% R-square. Conclusion: This study can provide useful information to develop effective programs for the change of exercise and dietary habits considering university students' stages of change according to the transtheoretical model.

Background: Cancer is a major health problem due to the aging population with increasing deaths. Family functioning is affected by cancer diagnosis and treatment. The aim of this study was to comparative analysis of the perception of family functioning by heads of families with and without cancer members during illness, focusing on changes or probable changes. Materials and Methods: This comparative study was conducted on two groups (families with a member of the cancer and controls without a family member with cancer). The families were of patients referred to the clinics and hospitals of Imam Khomeini, Taleghani and Omid of Urmia city, the number of samples being 148 for cases and 176for the control group. To collect the data, valid and reliable family functioning (FAD) was applied, a 60-item questionnaire with seven dimensions, with heads of families. To analyze the data SPSS- 23 Software was used for descriptive and analytical statistics. Significance level was defined p <0.05. Results: Among the seven items : problem solving, communication, roles, emotional response, emotional involvement, behavior control and overall functioning, only differences for average scores of problem-solving were statistically significant. Discussion: Contrary to common perception of severe damage for family functioning in families with cancer members, results of this study indicate that functioning in terms of family caregivers is more or less similar to that of the families with other diseases. Only in problem-solving item do these families experience more difficulty. Conclusion: According to the research findings, in nursing from families with cancer patient, it is recommended to focus more on the problem-solving item of the families.

This research sought to study viewers' perception of migrant women who wed Korean men following these women's level of specialty as shown on multi-cultural TV program by focusing on university students. Post test control group design method was utilized to conduct analysis, which demonstrates that there was a significant difference between the viewers on the professional migrant women and on the non-professional migrant women when it comes to the categories such as, 'Migrant women have specialized skills', 'migrant women have outstanding communication skills' and 'migrant women are independent minded.' Because of the existence (or non-existence) of professional careers as shown on TV program can affect viewers' perception of migrant women, it is necessary to develop measures such as development of expert group's advising system and to guarantee migrant women's diversity.
