This study is intended to suggest the method of text arrangement in order to enhance visual perception which would help darify its communication. One hundred subjects without restriction of gender and profession participated in each experiment :their reading time was measured by the 0.01 second. The Analysis of Variance(two-way ANOVA without interaction) was performed for each experiment and the p value was 0.0001 which implies that there was a strong consistency among test results. Based on the first results, it is found that there is a consistent relationship between type size and text line length, and the following discovery was made ; the most effective ratio of type size to line length is approximately 1 :8. Judging from the Second and Third results, it seems that the vertical text arrangement is most efficient for reading regardless of text line length. So to make same rreading direction is more important than to narrow down the eye moving distance between column and column for efficient visual flow. This research supports the view that considering efficient eye movement on text, it is important to understand the mentioned variables that affect visual interpretation.

This study was to examine the pattern of visual interpretation in the process of eye-tracking. I categorized the subjects' observation inclination for analysis so that I could find out which element the user observing the space concentrated and explored. First, for 2 minutes of observation, there occurred 171 times of eye-fixations and 9.8 times of observation frequency on average, which showed that the subject, through this observing fixation, spent 44.5% of the entire time performing the visual activity in order to acquire the "visual understanding" of the lobby-space. Second, I found out that there was a consistent observation type as the time passed. I could categorize the subjects observing the space into 6 concentrating types and 3 discontinuing ones of observation types, which category can be utilized as data for analyzing the subjects' characteristics at space-observation. Third, the type, which was so intensive as to get the visual understanding on the space, was mostly of the case that (1) the subject had a kind of high degree of observation type, exploring the space, again having high degree of the observation type [Type A], (2) the subject repeated the concentration from the early part to the latter [Type C], which can be considered to be the observation type generally shared. Fourth, in the case of observing the space, 45.8% of the subjects showed a high rate of concentration at the time of starting the observation and in less than two minutes. The subjects of type A can be considered to understand the space visually by distinctively repeating the concentration and exploration.

This research has been carried out with the objects of sporting goods shops to find out what structure of those shops raises more interest from customers. The tracking eyes on the objects which are the same but seen to have different structures has revealed the followings. Customers' visual appreciation of Reverse left/right Images (11.1) was found to be higher than that of Original Images (10.6). Furthermore, the reverse left/right image of the space also was found to attract more interest from customers, which led them to have longer observation. The below is about the interpretation of the spatial exploration by observation time and the appreciation of its visual content in line with the experiment objects of selling spaces. The longer the space was observed, (1)the higher the expansive searching of space was, (2)the more spots were observed as if they did not know what to see after they first observed at early hours, (3)later (in the time range of 64~73 seconds) they came to look at the spots in which they got interested, (4)and then again they suddenly got lost what to see. When the change of observation characteristics by time range is reviewed, it can be seen that the searching of original images is changed from Divergent Feature to Convergent Feature when the observation time increases from the early stage of observation to the later. On the contrary, the reverse left/right images were found to have the opposite searching features, that is, from convergent exploration to divergent exploration. These findings show that the reverse left/right images of the sporting goods shops, which were the experiment objects, have more factors attracting customers' attention and interest and that it is the very shop-structure which makes customers have better visual appreciation of those shops.

The purpose of this study is to identify the differences in persuasive effectiveness of visual merchandising between consumers in Korea and China including the moderating roles of shopping value in effectiveness of visual merchandising. For the cross-cultural experiment, 2(degree of sensuousness of VM: high vs. low)${\times}$2(involvement: high vs. low)${\times}$2(nation: Korea vs. China) factorial design were used. A total of 480 questionnaires allocating 60 students to each group were distributed. The results were as follows. First, Chinese consumers were likely to respond favorably regardless of the degree of sensuousness of VM, while Korean consumers were more positive in high degree of sensuousness of VM. Second, aesthetic cognition of VM and attitude toward VM had positive influences on brand cognition in both countries. Third, Korean consumers with greater recognition of aesthetic attributes of VM had more positive brand attitude, while Chinese consumers with greater recognition of utilitarian attributes of VM had more positive brand attitude. Fourth, there were moderating effects of shopping value in persuasive effectiveness of VM in Chinese consumer group, while there were no significant moderating effects in Korean consumer group. With the cross-cultural interpretation of the fin-dings, strategic implications and suggestions for the global fashion retailing, specifically fashion visual merchandising, are provided.

This study aims at investigating the perceptions of science teachers about the role of visual representations in the teaching of electromagnetism, and finding out how science teachers use visual representations in their teaching of electromagnetism and the difficulties they experience in dealing with those representations. A total of 121 science teachers responded to the online survey. The results showed that most of the teachers agreed to the significance of using visual representations in the classroom but regarded their role as means of simply delivering science knowledge rather than constructing or generating knowledge. For the three visual representations widely used in teaching of electromagnetism in secondary schools (electrostatic induction on electroscope, magnetic field around current carrying wire, structure and principle of electric motor), the teachers preferred teacher-centered use of visual representations rather than student-centered and teacher's construction of representations were the most frequent among four types of use; interpretation, construction, application, and evaluation. The difficulties of teaching with these three visual representations were categorized into several factors; teachers, students, the characteristics of the representations, and lack of resources and classroom environment. Teachers' limited perceptions about the role of visual representations were associated with the ways of using visual representations in their teaching. Implications for the effective use of visual representations for science learning and teaching were discussed.

In previous study, visual representation competence taxonomy (VRC-T), which is composed of two dimensions, was developed for the purpose of promoting effective visual representation use and research in science education. In this study, elementary school students' visual representation competence for shadow phenomenon was investigated using VRC-T. In terms of visual representation competence, 'interpretation' was the highest score, followed by 'construction' and 'integration'. It also showed that students' visual representation competence was not high even after learning shadow-related units in the regular curriculum. On the other hand, text-based scientific knowledge was not correlated with all categories of visual representation competence. This indicates that there is a need to emphasize visual representation more in science class. Finally, hierarchical relationship among cognitive processes of VRC-T was explored according to ordering theory. If the tolerance level is somewhat loosened, a linear hierarchical relationship was found between the six cognitive processes. This suggests that VRC-T is an analytical framework that can be useful when designing assessment tools, tasks, and science class activities to enhance visual representation competence.

The aim of this research is to explore the potential of analogy and metaphor as design strategies for supporting the creative design thinking. For the empirical research on analogical and metaphoric process in designing, we conducted design experiments that consist of three different conditions of given items as stimulation for design inspiration: baseline, surrealist paintings, and housing design collections. The results were analyzed using a protocol analysis in order to obtain more systmatic interpretation of the design processes and strategies. As a result, it was noted that students are more apt to read visual information rather than semantic information in the given items. Instead of the representation of their senses or feelings from the paintings, they visualized the analogical images of the paintings for the design representation. However, analogical and metaphoric thinking derived from the given items seem change a designer's perspective, thus bring a novel interpretation on design problems, and eventually more creative and meaningful design ideas. An extended research using one-semester training and observation of the design studio process is introduced as a follow-up study for this paper. This research will investigate the long-term effect of the analogy and metaphor on the design thinking.

Clinical evaluations, nerve conduction studies, and electromyography play major complementary roles in electrophysiologic diagnoses. Electromyography can be used to assess pathologic changes and localize lesions occurring in locations ranging from motor units to anterior-horn cells. Successfully performing electromyography requires knowledge of the anatomy, physiology, and pathology of the peripheral nervous system as well as sufficient skill and interpretation ability. Electromyography techniques include acquiring data from visual/auditory signals and performing needle positioning, semiquantitation, and interpretation. Here we introduce the basic concepts of electromyography to guide clinicians in performing electromyography appropriately.

Objective : The purpose of this study is to report the improvement in a patient who had Tourette syndrome treated with Hoeyeoksan based on Shanghanlun provisions. Methods: The symptoms of the patient were checked on days 14, 34, 62, 82, 103, and 119 after administration of Hoeyeoksan. Tourette syndrome was evaluated using Yale Global Tic Severity Scale (YGTSS), and oversleep and constipation were evaluated using visual analog scale (VAS). In addition, new clinical implications for the interpretation of Shanghanlun provision 318 were reviewed. Results: Daily tics occurred ten times a day for 14 days after the initial diagnosis but decreased to eight times a day after 34 days, six times a day after 62 days, five times a day after 82 days, twice a day after 103 days, and once a day after 119 days after administration of Hoeyeoksan. Oversleep and constipation improved together with Tourette syndrome. Conclusions: In this study, we observed that Hoeyeoksan had a therapeutic effect by improving the chief complaint of the patient. Hence, the interpretation of Shanghanlun provision 318 must include a patient's behavioral and sleep patterns as predisposing factors of Tourette syndrome.

Objective: This study aimed to report the improvement of a patient with chronic insomnia who was treated with Baekho-tang based on the Shanghanlun disease pattern identification diagnostic system (DPIDS). Methods: The patient's symptoms were checked on days 19, 37, and 52 after taking Baekho-tang. Chronic insomnia was evaluated by the degree of insomnia, hours spent asleep, and the number of times the patient woke up during the night, which were all assessed by a visual analog scale (VAS) with the Leeds Sleep Evaluation Questionnaire. In addition, new clinical implications for the interpretation of the 350th Shanghanlun provision were reviewed. Results: After administering Baekho-tang for 52 days, based on the 350th Shanghanlun provision according to the DPIDS, the VAS score decreased from 10 to 1. Conclusions: The patient recovered from chronic insomnia. This case report suggests that the words "滑," "厥," and "裏" in the 350th provision of Shanghanlun mean physical and psychological causes of insomnia. In addition, Baekho-tang had a therapeutic effect in improving the chief complaint of the patient. Therefore, the interpretation of the 350th Shanghanlun provision requires a new definition that includes the patient's lifestyle, family conflict, and past history of the patient as a cause of chronic insomnia.
