  • Purpose: This study examined the effects of nutritional education related to sugar in elementary school children on nutritional knowledge, attitude, and dietary behavior. Methods: A questionnaire survey on the knowledge, attitudes, and intake related to sugar was conducted on 572 students in grades 4-5, who were attending five elementary schools in Seoul and Gyeonggi-do. Results: Among the survey subjects, 270 (49.8%) were cognitive in education, and 302 (50.2%) were non-cognitive. The sugar-related knowledge score was 3.67 points in the cognitive education group, which was significantly higher than the 3.55 points in the non-cognitive group. The rate of checking the sugar content in the nutrition label was 31.2% in the cognitive education group, which was significantly higher than in the non-cognitive group, 15.4%. The cognitive education group had a higher intake frequency of unsweetened candy, jelly, and raw fruits, and higher sugar intake of unsweetened bread, white milk, and raw fruits than the non-cognitive group. In the case of the cognitive education group, the total knowledge score showed a positive correlation with the food behavior scores, and a negative correlation with the frequency of purchasing snacks after school, and the average sugar intake per day. In the cognitive education group only, the education of nutrition teachers was analyzed as a factor to reduce the total sugar intake. The cognitive group of sugar education tried to eat foods with a lower sugar content than the non-cognitive group, and nutrition education was an important factor affecting the sugar intake. Conclusion: To reduce the sugar intake of elementary school students, it will be necessary to practice oriented-nutrition education by nutrition teachers continuously. In addition, it is important to develop and disseminate various types of nutrition education materials related to sugar that can be utilized easily by nutrition teachers.

  • This study would provide the basic data informative for establishing a VMD strategy, covering design and marketing for business owners and prospective entrepreneurs, including the persons concerned with the food and beverage industries by investigating the relationships of the impacts of several factors in the cognitive dimension factors of VMD in food and beverage stores on consumers' emotional response and behavior intention and the mediating effect of emotional responses, applying the concept of VMD to the food and beverage industries. To check this research purpose, data were collected through a survey, conducted with various consumers in their 20s through 60s who have experienced the use of food and beverage stores. The period of the survey was from September 20 through October 10, 2017, 202 copies of questionnaires were collected without missing values and used as data for the final analysis. As for the analysis of the data, using SPSS statistical software, frequency analysis and descriptive statistics, analysis of reliability and validity, correlation analysis, single and multiple regression analysis were conducted. According to the results of this study, first, the relationship of the impact between the VMD cognitive dimension of food and beverage stores and customers' emotional responses was statistically significant. In concrete, all factors of VMD cognitive dimension, including the factors of suitability and daily escape had positive (+) impacts on positive emotions. Second, as a result of an analysis of the impact of emotional responses felt in the process of visiting the food and beverage stores on customers' behavior intention, it turned out that positive emotions had a positive (+) impacts on visit intention and recommendation intention while negative emotions did not have any impacts on visit intention and recommendation intention. Third, as a result of an analysis of the impact of VMD cognitive dimension on behavior intention, the suitability and balance of the VMD cognitive dimension had positive (+) impacts on visit intention while daily escape and functionality had positive (+) impacts on recommendation intention. Fourth, as a result of checking if emotional responses had a mediating effect in the relationship between the VMD cognitive dimension and behavior intention, positive emotions had a full mediating effect while there was no mediating effect of negative emotions between the VMD cognitive dimension and behavior intention. In conclusion, this study found that the VMD cognitive dimension of food and beverage stores affected consumers' emotional responses and that emotional responses were a factor affecting behavior intention and proved that consumers' emotional responses differed depending on the factors in the cognitive dimension. Thus, in food and beverage stores, it would be necessary to make effective designs of the stores and differentiate the presentation of them through utilizing detailed factors of the cognitive dimension of VMD. Also, the results of this study could be utilized as the appropriate marketing tools for customers in food and beverage stores and as the basic data for establishing the strategy.

  • This paper investigates the effects of entrepreneurs' cognitive biases on business opportunity evaluation, given their strong entrepreneurial spirit, which is characterized by innovation, proactivity, and risk-taking. When making decisions related to business activities, entrepreneurs typically make rational judgments based on their knowledge, experience, and the advice of external experts. However, in situations of extreme stress or when quick decisions are required, they often rely on heuristics based on their cognitive biases. In particular, we often see cases where entrepreneurs fail because they make decisions based on heuristics in the process of evaluating and selecting new business opportunities that are planned to guarantee the growth and sustainability of their companies. This study was conducted in response to the need for research to clarify the effects of entrepreneurs' cognitive biases on new business opportunity evaluation, given that the cognitive biases of entrepreneurs, which are formed by repeated successful experiences, can sometimes lead to business failure. Although there have been many studies on the effects of cognitive biases on entrepreneurship and opportunity evaluation among university students and general people who aspire to start a business, there have been few studies that have clarified the relationship between cognitive biases and social networks among entrepreneurs. In contrast to previous studies, this study conducted empirical surveys of entrepreneurs only, and also conducted research on the relationship with social networks. For the study, a survey was conducted using a parallel survey method using online mobile surveys and self-report questionnaires from 150 entrepreneurs of small and medium-sized enterprises. The results of the study showed that 'overconfidence' and 'illusion of control', among the independent variables of entrepreneurs' cognitive biases, had a statistically significant positive(+) effect on business opportunity evaluation. In addition, it was confirmed that the moderating variable, social network, moderates the effect of overconfidence on business opportunity evaluation. This study showed that entrepreneurs' cognitive biases play a role in the process of evaluating and selecting new business opportunities, and that social networks play a role in moderating the structural relationship between entrepreneurs' cognitive biases and business opportunity evaluation. This study is expected to be of great help not only to entrepreneurs, but also to entrepreneur education and policy making, by showing how entrepreneurs can use cognitive biases in a positive way and the influence of social networks.

  • Purpose: For now, cognitive load is assessed based on survey-based methods, which can be difficult to track the amount of cognitive load in real-time. In this study, we investigated the difference in electrophysiological activation due to different levels of cognitive load not only at sensor-level but also at source-level using electroencephalogram that might be potentially used for quantitative cognitive load evaluation. Materials and Methods: In this study, ten healthy subjects (mean age 24.3 ± 2.1, three female) participated the experiment. All participants performed 4 sessions of n-back task in different difficulties: 0-, 1-, 2-, and 3-back during electroencephalogram recording. For sensor-level analysis, we calculated the event-related potential and event-related spectral perturbation while low resolution brain electromagnetic tomography (LORETA) to estimate the source activation. Each result was compared between different workload conditions using statistical analysis. Results: Statistical results revealed that the accuracy of the task performance was significantly different between different cognitive loads (p = 0.018). The post-hoc analysis confirmed that the accuracy of the 3-back task was significantly decreased compared to 1-back condition (p = 0.018), but not with 2-back condition (p = 0.180). ERP results showed that P300 target amplitude between 1-back and 3-back had a marginal difference in Cz (p = 0.059) and Pz(p = 0.093). A significant inhibition in Cz high-beta activation (p = 0.017) and decrease in source activation of right parahippocampal gyrus was found in 3-back condition compared to 1-back condition (p < 0.05). Conclusion: In this study, we compared the sensor- and source-level differences in electroencephalogram between different levels of cognitive load, that were found to be in line with the previous reports related to cognitive load evaluation. We expect that the outcome of the current study can be used as a feature to establish a quantitative cognitive load assessment system.

  • Objectives: To identify the current status of Korean medical practice pattern, diagnosis and treatment of dementia through recognition survey, and to use it as a preliminary data for various dementia research. Methods: Questionnaires were developed through expert meetings. The disease was defined as dementia and mild cognitive impairment, and areas were designated to practice pattern, diagnosis and treatment. From December 18, 2016-January 18, 2017, 221 respondents, including 36 neuropsychiatrists of Korean Medicine and 185 general physicians (including other medical specialists) were included. Results: 1. In both groups, the most commonly used KCD (Korean standard classification of disease and cause of death) were in the order of Unspecified Alzheimer's Dementia (F00.9), Mild Cognitive Impairment (F06.7), and Unspecified Dementia (F03). 2. The most commonly used pattern identification were zang-fu and qi-blood-yin-yang in both groups. 3. Diagnostic evaluation tools were mainly conducted by MMSE, radiologic examination, K-DRS, GDS and CDR in both groups. 4. Both groups reported using acupuncture and herbal medicine mainly. 5. In both groups, the acupuncture method was used extensively in the order of Body, Scalp, and Sa-Am. 6. Neuropsychiatrists used a variety of herbal medicines such as Wonjiseokchangpo-san (Yuanzhushichangpu-san), Yukmijihwang-tang (Liuweidihuang-tang), Palmijihwang-won (Baweidihuang-won), Sunghyangjungki-san (Xingxiang Zhengqi-san) and Ondam-tanggami (Wendan-tangjiawei). General physicians used a variety of herbal medicines such as Ondam-tanggami (Wendan-tangjiawei), Bojungikgi-tang (Buzhongyiqi-tang), Yukmijihwang-tang (Liuweidihuang-tang). 7. Neuropsychiatrists used a variety of Korean herbal preparation products (benefit and non-benefit) such as Ekgan-sangajinpibanha (Yigan-sanjiachenpibanxia), Yukmijihwang-tang (Liuweidihuang-tang), Jodeung-san (houteng-san), Palmijihwang-won (Baweidihuang-won). General physicians used a variety of Korean herbal preparation products such as Bojungikgi-tang (Buzhongyiqi-tang), Banhabaegchulcheonma-tang (banxiabaizhutianma-tang), Yukmijihwang-tang (Liuweidihuang-tang), Ekgan-sangajinpibanha (Yigan-sanjiachenpibanxia), Palmijihwang-won (Baweidihuang-won). Conclusions: By confirming awareness of Korean medical doctors treating dementia in clinical fields and understanding differences between neuropsychiatrists of Korean medicine and general physicians, it can be used to understand guideline users' needs and confirm clinical questions during development of future clinical practice guidelines for dementia.

  • Although telephone surveys are an attractive alternative to household interviews it is important to determine whether the data collected by the two methods are comparable. To answer this question, findings from the telephone survey literatures are examined in the view point of i) direct effect which means expressions of preference of the interview detail of answers on open questions and item missing data rates ii) statistical estimates and iii) differences of interviewers and data collection modes. Differences are explained by social desirability effects on the telephone, cognitive ability of the survey question, and mode effects and interviewer effects.

  • Purpose: This study sheds light on the need for trust in buyer-seller relationships in supply chains and explores why long-term orientation is important. It also investigates the effect on relationship performance. This study provides implication on how to build robust supply chains. Methodology: A survey was conducted with firms with supply chains in South Korea. A total of 350 valid questionnaires were analyzed through Entrust Survey-a sampling company. Structural equation modeling (SPSS 18.0 and AMOS) was employed to test the hypotheses. Results: Cognitive trust had a positive effect on emotional trust. Emotional trust had a positive effect on long-term orientation but did not have a significant effect on relationship performance. Long-term orientation was proportionate to relationship performance. Conclusions: Trust is a critical factor in supply chains. As business environments are rapidly changing, the uncertainties are also meaningful. Supply chains have collapsed owing to COVID-19, the Russia-Ukraine war, and the U.S.-China trade war, and they are only just recently being rebuilt. Maintaining relationships with supply-chain partners is vital, and promoting cognitive and emotional trust is necessary.

  • 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.
