  • Purpose: The purpose of this study was to investigate differences in the control process to satisfy spatial and temporal constraints imposed upon the anticipation timing response by analyzing the effect of spatio-temporal accuracy demands on eye movements, response accuracy, and the coupling of eye and hand movements. Research design, data, and methodology: 12 right-handed male subjects participated in the experiment and performed anticipation timing responses toward a stimulus moving at three velocities (0.53m/s, 0.66m/s, 0.88m/s) in two task constraint conditions (temporal constraint, spatial constraint). During the response, response accuracy and eye movement patterns were measured from which timing and radial errors, the latency of saccade, fixation duration of the point of gaze (POG), distance between the POG and stimulus, and spatio-temporal coupling of the POG and hand were calculated. Results: The timing and radial errors increased with increasing stimulus velocity, and the spatio-temporal constraints led to larger timing errors than the temporal constraints. The latency of saccade and the temporal coupling of eye and hand decreased with increasing stimulus velocity and were shorter and longer respectively in the spatio-temporal constraint condition than in the temporal constraint condition. The fixation duration of the POG also decreased with increasing stimulus velocity, but no difference was shown between task constraint conditions. The distance between the POG and stimulus increased with increasing stimulus velocity and was longer in the temporal constraint condition compared to the spatio-temporal constraint condition. The spatial coupling of eye and hand was larger with the velocity 0.88m/s than those in other velocity conditions. Conclusions: These results suggest that differences in eye movement patterns and spatio-temporal couplings of stimulus, eye and hand by task constraints are closely related with the accuracy of anticipation timing responses, and the spatial constraints imposed may decrease the temporal accuracy of response by increasing the complexity of perception-action coupling.

  • This study explored the conceptual framework of dieticians' intentions to recommend functional food and the mediating role of consumption frequency. A web-based survey was designed using a self-administered questionnaire. A sample of Korean dieticians (N=233) responded to the questionnaire that included response efficacy, risk perception, consumption frequency, and recommendation intention for functional foods. A structural equation model was constructed to analyze the data. We found that response efficacy was positively related to frequency of consumption of functional foods and to recommendation intention. Consumption frequency also positively influenced recommendation intention. Risk perception had no direct influence on recommendation intention; however, the relationship was mediated completely by consumption frequency. Dieticians' consumption frequency and response efficacy were the crucial factors in recommending functional foods. Dieticians may perceive risks arising from the use of functional foods in general, but the perceived risks do not affect ratings describing dieticians' intentions to recommend them. The results also indicated that when dieticians more frequently consume functional foods, the expression of an intention to recommend functional foods may be controlled by the salience of past behaviors rather than by attitudes.

  • Until now, Korea carried out disaster management under the perception that the central government or the local government bodies are totally responsible. However as the size of disasters become larger, the capacity of the public disaster management did not live up to the expectations. To analyze this issue, this research conducted interviews on disaster response readiness by "individual resident-residents cooperation-public/private collaboration" according to each preparedness-response-recovery stage, as resident representatives (Head of Ri, Head of Tong) as subjects. Based on the interviews, surveys were conducted to deduct the necessary factors needed for the general residents to exhibit disaster prevention capabilities. The surveys consist of 6 factors-risk perception, evacuation inductively, individual evacuation response, disaster prevention system, lookout & precaution, information communication.

  • This paper examines the Chinese government's response to four epidemic crises, including COVID-19, and analyzes the similarities and differences in these responses. It argues that while the Chinese government learned from previous epidemics and improved its handling of subsequent outbreaks, a significant variation occurred during the COVID-19 pandemic, which had a detrimental impact globally. Existing scholarly research on China's epidemic responses has often been limited in scope, focusing on individual crises and neglecting the central-local government relationship in crisis decision-making. By adopting a comprehensive approach, this paper delves into the nuanced dynamics of China's responses to these epidemics. It highlights the variations in responses, attributing them to the Chinese government's fear of undermined legitimacy and its consideration of its international image. The government's recognition of the importance of public perception and trust, both domestically and globally, has shaped its crisis management strategies. Through a detailed analysis of these factors, this paper contributes to a deeper understanding of the variations observed in China's epidemic responses. It emphasizes the significance of the central-local government relationship and the government's international image in determining its actions during epidemics. Recognizing these factors can provide policymakers and researchers with insights to shape future epidemic response strategies and foster effective global health governance.

  • This study attempts to understand how the perception of service quality as well as shopping motives influence on the emotional responses in store shopping, and to examine how these relevant variables influence on the store satisfaction. The 463 questionnaires were collected from the purchasers in department stores, fashion specialty stores, and national brand franchise stores. The results of this study are as fellows: 1. In regard to shopping motives, two dimensions of product motive and experiential motive were identified, explaining 47.39% of shopping motives. 2. In regard to emotional response, two dimensions of pleasure emotion and displeasure emotion were identified, explaining 65.95% of emotional responses. 3. Shopping motives led to the store satisfaction after the perception of service quality and then the experience of pleasure emotion. These related variables explained 60% of the store satisfaction. 4. The consumers of fashion specialty store showed the highest product motive, whereas the consumers of department stores showed the highest displeasure emotion in the store. As the results showed, customers' shopping motives influence their perception of service quality and pleasure emotion. Therefore, in order to stimulate shopping motives, the store environment that can give customers pleasure and opportunity to pursue various experiences should be provided. As the service quality is a very important variable that leads pleasure emotion in the store, sales persons should be trained to satisfy customers.

  • The object of this study was to investigate the relationship between stress and the extent of coronary artery stenosis in 101 patients with coronary artery diseases. Global assessment of recent stress(GARS) scale and perceived stress response inventory were used to measure perception for stressors and stress responses. Biological variables such as the extent of coronary artery stenosis, the number of the affected lesions on coronary angiography, serum Low Density Lipoprotein(LDL)-cholesterol, High Density Lipoprotein(HDL)-cholesterol, and total cholesterol were measured in all the subjects. Scores of perceived stress related to changes in relationship and overall global scores on GARS scale had significantly positive correlation with the extent of coronary artery stenosis. On the other hand, scores of percieved stress related to changes in relationship and changes or no changes in routine had significantly positive correlation with the number of the lesions. Scores of perceived stress related to change or no change in routine also positively correlated with serum level of LDL-cholesterol and total cholesterol. In contrast, general somatic symptoms negatively correlated with the extent of coronary artery stenosis. Impulsive-aggressive behavior negatively correlated with the number of the lesions. However, impulsive-aggressive thinking positively correlated with LDL-cholesterol. The above results suggest that perception for stressors may negatively affect the extent of coronary artery stenosis, the number of the lesions, serum LDL-cholesterol and total cholesterol. However, some stress responses showed inconsistent effect on the above biological variables. Thus, strategies designed to modify perception for stressors and some stress responses are likely to help the patients minimize the extent of coronary artery stenosis and prevent the diseases.

  • In the third comprehensive library development plan, the formal and informal social safety space function of the library is used as a project. Therefore, this study investigated whether libraries were designated as evacuation facilities and related service status, and librarians' awareness, perception and attitude toward disaster and disaster response services. Based on this, it was intended to propose a direction to activate disaster and disaster response services. The research results are as follows. First, it is necessary to improve the perception of librarians who are the service providers. Second, discussions on spatial aspects, such as temporary or permanent, are needed. Third, development of disaster and disaster-related service models is required. Fourth, the administration's support and management are essential for the effectiveness of the library's function as a social safety space. Fifth, when developing guidelines for the role of libraries as social shelters and related services, specific details to address the concerns of individual libraries and librarians need to be specified.

  • The purpose of this study is to provide a fundamental research data that is necessary in an education of dietary life so that the students have sound dietary life through a right food purchase after investigating perception of children's dietary habit and activity, food labelling, and nutrition labelling for 400 students of the 5 and 6th grades. The result of the study are as followings. In terms of perception questions over food labelling, on the whole, "know it little bit" was the highest. Girls and country was higher than boys and city. A list of item that is important in contents of food labelling were period of circulation, data of manufacturing, price, used ingredient, origin of product, nutrition contain labelling, manufacturer, quantity in contents(quantity, the number). A meaningful difference was shown in gender(p<.05) and area(p<.01). In 30 perception questions over nutrition labelling, "know it little bit" was the most, and girls and country were higher than boys and city. In ascertaining nutrition labelling at the time of purchasing the food, "look often" was the most. Girls and city were higher than boys and Gun in average but no difference was statistically shown in knowledge mark in utilization and perception of nutrition labelling. The response rate in girls(p<.01) and country(p<.05) was higher in a question of "if nutrition labelling is displayed, nutriment that is harmful for our body will be eaten less" and girls' response rate was higher in the question of "being educated for my health". Therefore, practice centered nutrition education is necessary to purchase the food after ascertaining food nutrition labelling out of an attitude in habitually purchasing the processed food. The students develop comprehensible food nutrition labelling the direction to emphasizing nutrition educational labelling and recognizing that the healthy nutriment is contained without conventional and food safety centered labelling should be changed.

  • The purposes of the study were 1) to evaluate the visual image of colored Korean traditional dress for woman 2) to analyze the colors and, color combinations effect on the image perception using gestalt theory. The research method was a quasi-experimental with a between subjects design. The experimental materials developed for the study were a set of stimuli and a response scale. The stimuli was consisted of 17 drawings of females wearing Korean tradinational dress, by using CAD simulation. A response scale consisted of semantic differential scales. The subjects were 1138 undergraduate students of Taejon city, Chungnam province and Chungbuk province. Their responses to the semantic differential scales were analyzed using factor analysis, one-way ANOVA, Duncan's multiple range test, 1-test. Results were as follows; 1) The image of the stimulus was consisted of the 4 different dimensions.(sociability, evaluation, visibility, attractiveness) 2) Clothing colors had significant effects on image perception of the evaluation dimension, visibility dimension and attractiveness dimension in the mono-color set. The blue showed the most positive image on the evaluation dimension, and the yellow and the gray showed negative image on the same dimension. The yellow showed the most salient image and the gray showed the least salient image on the visibility dimension. The red showed the most attractive image and the green showed the least attractive image on the attractiveness dimension. 3) In hi-color set stimulus, the perceived image was influenced by color combinations. The yellow blouse-the red skirt set showed the most sociable image on the sociability dimension. The blue blouse-the green skirt set showed the most positive image on the evaluation dimension. The yellow blouse-the red skirt set showed the most salient image and the blue blouse-the green skirt set showed the least salient image on the visibility dimension. And the red blouse-the yellow skirt set showed the most attractive image on the attractiveness dimension. On conclusion the visual image of Korean traditional dress wearer was affected by dress colors and color combinations.
