Purpose. The purpose of this study was to investigate the effect of visual field training on visual function, visual perception and attention enhancement. Methods. We examined the changes of visual function and visual perception tests for children with mild developmental disabilities through vision therapy. Results. At the time of the initial visit of the child, the ability to control not only distant and near visual function, but also accommodation, was also very limited. Also, the visual perception score was measured at 80 points. Through vision therapy, it was confirmed that the improvement of control ability as well as the visual function and visual perception function test results were also improved to 108 points. Conclusion. It was confirmed that vision therapy results in an improvement of visual function, improved visual perception ability, as well as visual perception ability, It was concluded that visual function affected visual perception, and that vision therapy used in order to prevent visual function deterioration was found to be very helpful.

For mobile robot, recognizing its current location is very important to navigate autonomously. Especially, loop closing detection that robot recognize location where it has visited before is a kernel problem to solve localization. A considerable amount of research has been conducted on loop closing detection and localization based on appearance because vision sensor has an advantage in terms of costs and various approaching methods to solve this problem. In case of scenes that consist of repeated structures like in corridors, perceptual aliasing in which, the two different locations are recognized as the same, occurs frequently. In this paper, we propose an improved method to recognize location in the scenes which have similar structures. We extracted salient regions from images using visual attention model and calculated weights using distinctive features in the salient region. It makes possible to emphasize unique features in the scene to classify similar-looking locations. In the results of corridor recognition experiments, proposed method showed improved recognition performance. It shows 78.2% in the accuracy of single floor corridor recognition and 71.5% for multi floor corridors recognition.

This study investigated the cross-cultural differences in temperament among Chinese, Korean-Chinese, and Korean children. Subjects were 1,046(258 Korean-Chinese, 290 Chinese, and 498 Korean) 4th graders from Yanji in China and Seoul and Ulsan in Korea. The short form of the Early Adolescent Temperament Questionnaire Scale-Revised containing 10 scales of 54 items was translated into Korean for Korean and Korean-Chinese children and into Chinese for Chinese children and was administered to children via home-room teachers. Chinese children rated themselves higher on activation control, attention, and pleasure- and perceptual-sensitivity subscales than other groups. On the contrary, Chinese-Korean children rated themselves higher on the affiliation subscale and Korean children rated themselves higher on the aggression subscale than other groups. There were larger gender differences among Chinese and Korean-Chinese than among Korean children: Gender difference was found in activation control, aggression, and attention subscales among Chinese children and in affiliation, aggression, attention and fear subscales among Korean-Chinese. There was only significant difference in pleasure sensitivity among Korean. Rapid westernization in Korea seems to be responsible for this result. Since there were significant differences of temperament between Korean and Korean-Chinese, and between Chinese and Korean-Chinese, it was interpreted that children's temperament is influenced by both their environment and genetic endowment.

This paper is a study on what kind of effect non-verbal communication in mobil electronic commerce has on purchase intention and visual attention. For this purpose, the screen of mobile shopping mall produced arbitrarily was exposed to the experimental group and the control group. The experimental group was exposed to the screen of mobile shopping mall that expressed non-verbal communication making use of cinemagraph images and the control group was exposed to the screen of mobile shopping mall based on still images. For the study, survey research and experimental research were conducted simultaneously. Data of survey research were analyzed by MANOVA and t-test, and by using eye-tracker experimental research recorded the duration of time that the subjects stared images. The results of experiment show that in non-verbal communication the experimental group that saw cinemagraph images recorded shorter average staring time than the control group that saw ordinary images, and the cinemagraph had statistically significant effect on visual attention as well. And it was analyzed that non-verbal communication had significant effect on the purchase intention of the experimental group, but had no effect on the purchase intention of the control group. The results can be interpreted that the people who saw cinemagraphs in mobile shopping environment had spent shorter time in seeing products than the people who saw ordinary images, but still the former came to have purchase intention on the products. The results of the present study can be useful for marketers who try to sell agrifood in mobile environment.

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most general childhood problems occurs locally and internationally, but the causes of ADHD are not cleared yet. Therefore, this study tried to examine some parts of the causes of ADHD closely, and finally contribute to the medical treatment of ADHD and its precautionary measures, by measuring and comparing concentration of minerals in hairs of the patients of ADHD and their control group's children. which can analyze the relevance to ADHD and the mineral content in human bodies, and mutual relations between toxic minerals and essential minerals in human bodies. After collection of hairs from 200 children(5 to 7-year-old, boys: 159 girls:41) diagnosed as ADHD by medical specialists based on the standard of DSM-IV diagnosis and their control group's 177 children(boys: 138 girls:39), the mineral concentration of samples was measured through ICP-MS and compared. And correlations between toxic minerals and essential minerals in human bodies among patients group was analyzed. All the toxic minerals(Pb, Hg, Al, Cd, As) of hairs analyzed in the study showed more higher range of concentration in patients group in comparison with their control group. Among them, the concentration of Pb(3.27 $\pm$ 3.82 ppm) and As(0.16 $\pm$ 0.15 ppm) in patients group were significantly high compared to their control group. And in this study Pb among toxic minerals showed negative correlation with Zn(r = -0.43), Mg(r = -0.15) among essential minerals. Cd among toxic minerals showed negative correlation with Zn(r = -0.20) among essential minerals. As among toxic minerals showed negative correlation with Ca(r = -0.14) among essential minerals.

Objective : This study was conducted to find out the electrophysiological abnormalities of the patients with attention-deficit/hyperactivity disorder(abbr. ADHD) through identifying the profiles of the event-related potentials. Methods : Through measuring event-related potentials of 20 patients with ADHD and 16 normal control children using Oddball paradigm, we evaluated the latencies and amplitudes of each wave form. Results : In the group older than 9 years old, the latencies that reflect selective attention and discriminative capacity of the patients with ADHD were significantly longer than those of normal controls, which suggests that patients with ADHD be more distractible to non-significant stimuli and that they be in lark of sustained attention and discriminative ability. Conclusions : We concluded that the patients with ADHD are more distractible to trivial stimuli than normal children but they lack discriminative, sustained ability of attention.
