In this study, we developed a module that can perform two functions at the same time through interworking between a personal recognition module and a heat detection module in the era of COVID-19. This can simultaneously solve the problem of compatibility of the personal recognition module that occurs in the existing system and the problem of secondary infection that can occur during congestion due to the separate implementation of heat detection. Therefore, in this study, NFC and Bluetooth motherboards were developed, and an array-type non-contact temperature sensor was applied to detect heat. The developed system is expected to be able to realize both access control of floating population and effective quarantine at the same time in public institutions or private companies that require AI automated access control. In addition, it is judged that it is possible to link the embedded programming and web programming implementation method using the module of the development system to the educational program.

Purpose: This study examined the correlations between the satisfaction and effectiveness of practical training and theory lectures under two conditions: face-to-face lectures and non-face-to-face online lectures. Methods: A survey of 436 public health student, whereafter SPSS 20.0 (IBM) was used on the data to conduct frequency, descriptive statistics, and exploratory factor analyses. The Cronbach's α value was estimated in a reliability analysis, and a simple regression analysis was conducted to verify the study hypothesis. Results: It was found that the students preferred pre-recorded lectures online for both practical training and theory, claiming that when compared with face-to-face lectures, these non-face-to-face lectures meant a shorter commute and the ability to repeat the content. However, it was admitted that technical issues such as facilities or access difficulties and lower concentration could be a problem. The hypothesis that course satisfaction affects lecture effectiveness was verified, with both the practical training and theory lectures found to have a statistically significant positive (+) effect. The explanatory power of student satisfaction on the effectiveness of the theory component was slightly higher than that of the practical training component, with the students having more positive perceptions on the necessity of face-to-face lectures in practical training than they did for those in theoretical instruction. Conclusion: Providing non-face-to-face online theory courses and face-to-face practical training courses could increase student satisfaction and lecture effectiveness.

Purpose: This study aimed to identify the factors influencing post-traumatic stress disorder in intensive care unit nurses in dedicated hospitals for coronavirus disease of 2019 (COVID-19) during the peak of the outbreak. Methods: This study used a cross-sectional correlational design. A total of 100 participants completed questionnaires comprising the Impact of Event Scale-Revised (IES-R), coping strategy indicator, social support, and post-traumatic growth. Post-traumatic stress disorder was classified as normal, mild risk, and high risk. Data were analyzed using 𝛘² test, Fisher's exact test, Kruskal-Wallis test with multiple comparison analysis, Pearson correlation coefficient, and multinominal logistic regression analysis. Results: Fifty seven nurses (57.0%) had a high risk of post-traumatic stress. Higher levels of post traumatic stress were associated with higher levels of social support seeking, and higher levels of avoidance, and lower levels of social support from supervisors. Higher post traumatic growth was correlated with higher social support for seeking coping, and problem solving coping strategies, and social support from supervisors and colleagues. Post-traumatic stress risk was associated with social support seeking and supervisors' social support. In addition, a higher risk of post-traumatic stress was related to COVID-19 work duration and supervisors' social support. Conclusion: Supportive programs, including increasing social support and building coping skills, may be suggested to safeguard the mental health of critical care nurses during the pandemic.

The prevalence of atopic dermatitis (AD) in children has increased dramatically in recent years. Although AD has genetic determinants, this rapid increase is most likely due to changes in environmental influences--for example, dietary changes. The purpose of this case-control study was to assess the relationship between the risk of developing AD and dietary factors, including eating habits, food intake, and the consumption of various functional foods in children at ages of 7 or 8 years. 143 AD patients and 335 healthy children participated in this study. A mini-dietary assessment was utilized to evaluate the food intake and dietary patterns of the children, and other information, including demographic and socioeconomic characteristics, eating habits, and the frequency of functional food use was collected using a questionnaire. The results demonstrated that, among the demographic and socioeconomic factors assessed in this study, female gender, mother's employment, and the family history of AD significantly increased the risk of AD. However, no differences in dietary habits and specific food intake between AD patients and healthy controls were identified. On the other hand, the frequencies of taking multivitamin supplements, Spirulina, or gamma-linoleic acid were significantly higher in AD patients than in the controls. These data indicate that alterations in eating habits and the intake of certain foods may not be a critical cause associated with the risk of AD in school-age children, and caution should be taken in recommending food elimination diets for the purpose of preventing AD. Further studies are required in order to determine whether the intake of specific nutrients could contribute to the increase or prevention of the development of AD in school-age children.

This study was carried out to investigate the physicochemical characteristics, intake rate, and sensory properties of kimchi provided to elementary school foodservice in Seongnam. Average amount of kimchi intake at the elementary school foodservice for lower grade(1~3) students and higher grade(4~6) students was 7.15 g(23.83%) and 11.15 g(37.17%) respectively. The physicochemical properties of kimchi provided to the school foodservice in Seongnam were different between head cabbage kimchi(Pogi kimchi, H product) and head cabbage kimchi for children(C product). The head cabbage kimchi showed the pH 4.31~4.65(average pH 4.45), 6.86~8.38 $^{\circ}Brix$(average sugar content 7.74 $^{\circ}Brix$), and salinity 1.36~2.20%(average 1.73%) whereas the head cabbage kimchi for children indicated the pH 4.23~4.45(average pH 4.32), 7.68~8.48 $^{\circ}Brix$(average sugar content 8.18 $^{\circ}Brix$), and salinity 1.38~1.80%(average 1.65%). The result of the sensory evaluation of head cabbage kimchi and head cabbage kimchi for children indicated that there was significant difference by grades and gender. Higher graders tended to prefer less sweet, less sour and salty kimchi, and girls preferred sweet and sour kimchi more than boys. Therefore, it is required to develop kimchi for children considering sensory characteristics by grades and gender.
