  • This research was to examine the understandings of elementary school teachers on the phenomena related to light and image, and to survey their perception change related to learning contents of optics. The subjects were selected from the elementary teachers who were enrolled in a graduate course, 'Science education seminar' at an education college located in Chungchungbuk-Do, South Korea. Among the five students who exposed their perceptions clearly in the class, the three of them were selected who agreed to the proposal of the case study. To achieve the purpose of this study, semi-structured interviews following the conception test with the 3 elementary teachers were conducted. During the analysis of the data, additional interviews by phone, e-mail, and internet messenger were conducted if necessary. According to the results, all of the elementary school teachers lacked the scientific conceptions of the phenomena related to light and image. Unfortunately, their learning experiences did not help them to understand the scientific concepts. During the interviews, the teachers recognized the importance of the viewpoints of seeing, image, cognition of light, point light source to understand the phenomena related to light and image.

  • The objectives of this study were to investigate differences between image perceptions according to gender, place of residence, and fashion trend; and to examine how the image of preferred clothing was evaluated in each given area of fashion trend. Subjects were 386 schoolchildren (boys:196, girls:190) in Seoul, Daejeon, and Jinju, Korea. Based on a quasi-experiment study, a survey was conducted with a questionnaire providing different clothing images of fashion trend. Stimuli were 5 colored photo pictures of a girl wearing clothing according to fashion trend. The clothing used in the study met requirements of 2004 S/S trend of children's clothing. The high valued clothing sold in three target places were used. There was a significant difference in image perceptions between two sexes. Girls showed more positive attitude in image perceptions toward fashionable clothing in most areas than boys. Children from smaller towns evaluated the model clothing more fashionable. Schoolchildren preferred sporty clothing to the other fashionable clothing. In view of trend, romantic clothing normally viewed less dynamic were evaluated preferable clothing when children viewed the clothing active. Sports-wears were considered fashionable when they viewed the clothing neat and vigorous.

  • Image saliency detection is the basis of perceptual image processing, which is significant to subsequent image processing methods. Most saliency detection methods can detect only a single object with a high-contrast background, but they have no effect on the extraction of a salient object from images with complex low-contrast backgrounds. With the prior knowledge, this paper proposes a method for detecting salient objects by combining the boundary contrast map and the geodesics-like maps. This method can highlight the foreground uniformly and extract the salient objects efficiently in images with low-contrast backgrounds. The classical receiver operating characteristics (ROC) curve, which compares the salient map with the ground truth map, does not reflect the human perception. An ROC curve with distance (distance receiver operating characteristic, DROC) is proposed in this paper, which takes the ROC curve closer to the human subjective perception. Experiments on three benchmark datasets and three low-contrast image datasets, with four evaluation methods including DROC, show that on comparing the eight state-of-the-art approaches, the proposed approach performs well.

  • The purpose of this study was to examine the perception of health-related majors in their third year of college about the image of a dental hygienist as prospective dental personnels. The findings of the study were as follows: 1. Concerning perception of the image of a dental hygienist by geographic region, the college students from large cities gave 89.07 to that, and the college students from small and mid-sized urban areas gave 85.03. The former gave higher marks to the image of a dental hygienist, and the gap between the two was statistically significant. By department, the students who majored in physical therapy gave the highest score of 88.93, dental technology and radiology gave the second highest score of 86.91. The clinical pathology gave the third highest score of 83.28, and the gaps among them were significant. 2. As for their perception of the four subfactors(qualifications, roles, social participation and interpersonal relationship) of the image of a dental hygienist by geographic region, there were statistically significant gaps in their way of looking at the qualifications, roles and interpersonal relationship of a dental hygienist. By department, the physical therapy majors gave the highest marks to all the four subfactors. 3. When they were asked to give one or more answers to the question what affected their image building about a dental hygienist, the largest number of the students that accounted for 67.9 percent replied that the looks of dental hygienists whom they saw in dental clinics or hospitals impacted on their image of a dental hygienist.

  • The purpose of this study was to examine self-perception of body image and dieting behaviors by gender among high school students. The data were collected by a self-administered questionnaire during April, 2010, and analyzed by SPSS Windows V.18.0. The results were as follows. First, many respondents showed a desire to be underweight and regarded themselves as overweight, even though they had a normal BMI. Second, female respondents showed a higher level of concern about diet than male respondents. Third, male respondents received information about diet mostly from their family or friends, whereas female respondents received information from blogs, mini-homepages, or Kin-search on the Internet. Finally, female respondents showed a higher level of practice for fasting therapy than male respondents, whereas male respondents showed a higher level of practice for food therapy, drug therapy, oriental medicine therapy, and steam bath therapy. Therefore, high school should educate students to get right recognition and knowledge of diet.

  • The purpose of this research was to investigate the effects of clothing style and color of male casual wear on image perceptions and age evaluations. $4{\times}2$ (top color${\times}$trouser color) and $2{\times}3{\times}2$ (clothing style${\times}$clothing hue${\times}$clothing chroma) factorial designs were used as the experiment designs. Photoshop program was used to manipulate the clothing colors after creating photos of models wearing experiment clothing for stimulus. Subjects were 280 female college students from Seoul region and each subject responded to two stimuli. Factor analysis showed four factors of images of male casual wear; sociability, conspicuousness, softness and masculinity. Polo shirts were evaluated higher in sociability and softness than jumpers and nary blue trousers were evaluated higher in masculinity than beige trousers. High chroma clothing was assessed higher in sociability and conspicuousness than low chroma clothing. High chroma red jumpers displayed very sociable feel and low chroma blue jumpers displayed the lowest sociability. High chroma male clothing resulted in younger age perception but age was evaluated young when a black shirt was worn under the jacket when wearing a low chroma jacket.

  • The purpose of this study was to investigate the influences of adolescents' body image and communication with their parents on the alienation of male and female middle school students. The subjects were 253 middle school students. The data were analyzed with SPSS win 18.0 using Cronbach's ${\alpha}$, t-test, one-way ANOVA, Scheff$\acute{e}$ test and stepwise regression. The findings showed that problematic communication with the father was the strongest factor in explaining the alienation of male middle school students. The second strongest factor was the middles school student's open communication with the mother, and the third strongest factor was the middle school student's perception of physical health. Unlike male students, open communication with the father was the strongest factor in explaining the alienation of female middle school students. Problematic communication with the mother was the second strongest factor. Perception of physical appearance was the third strongest, and perception of physical health was the fourth strongest factor. Based on the results of the study, implications were discussed in terms of the alienation of male and female middle school students.
