  • The realization of carbon neutrality requires cooperation from various stakeholders and the utilization of a governance system. The criteria for participating members are crucial for the successful operation of governance, and it is especially necessary for experts who can provide scientific advice for policy implementation to share a framework for successful consensus. In this study, governance model theory and model structure, governance common success factors by case, and the application of governance cases in the climate and environmental sector of Seoul, were investigated and analyzed to derive common success factors in order to present the activity standards of the science and technology experts participating in governance. The study of the model theory suggested that the model structure is commonly composed of a basic condition-process-result structure, and it was confirmed that common success factors can be derived at the process stage which is the activity period of members. Through the case study of common success factors, overlapping factors were found to be reliability, accountability, transparency, networks, and related factors. The validity of the common success factors was verified using the analysis results of satisfaction survey data from Seoul Governance Committee participants. The results confirmed that reliability was the most valuable factor followed by networks, transparency, and responsibility, and it was found that the related factors were appropriately derived. The findings of this study are expected to be used as an activity factor for science and technology experts to increase the acceptability and effectiveness of carbon-neutral policies in the future.

  • Under the goal of investigating relations between emotional labor and sleep health according to the personality types of dental hygienists, who provide high quality medical service at dental clinics, this study surveyed 220 dental hygienists in Gumi city from July 2 to 21, 2010. The surveyed dental hygienists scored average 2.75 in emotional labor, which means their emotional labor was higher than average. Their emotional labor was in statistically significant relations with such general characteristics as educational background, place of work, salary, and drinking(p<0.05). The means of their emotional labor in six items were analyzed according to the personality types. As a result, personality type A had higher means in emotional labor than personality type B with statistical significance(p<0.05). The more stress they had from emotional labor, the worse their sleep health became. As for the relations between emotional labor and sleep health according to the personality types, the bad sleep health group accounted for 88.1% and recorded 2.85 mean scores in emotional labor, which was statistically significant(p<0.05), in personality type A. The regression analysis results of emotional labor in personality type A and sleep health indicate that the more emotional labor in personality type A they had, the worse their sleep health became. As for causality between personality type A and emotional labor, "difficulty with sleeping," "a feeling of lack of sleep when waking up," and "taking sleeping pills" had significant influences on the emotional labor of personality type A. Dental hygienist who owns the characteristics of personality type A, the more emotional labor, emotional stress of personality type A labor is high and unhealthy sleep affects the results were derived.

  • The purpose of the study was to develop an eating habit checklist for screening elementary school children at high risk of energy overintake. Dietary habits, food intake, anthropometric data were collected from 142 children (80 boys and 62 girls) in the 4th to 6th grades of elementary schools. Energy intake, fat intake, and percentage of Estimated Energy Requirement (%EER) were used as indices to detect the risk of energy overintake of the children. Pearson correlation coefficients were calculated between dietary habit scores and energy overintake indices in order to select questions included in the checklist. TV watching during the meal, meal speed, meal amount, overintake frequency, eatingout frequency, snack frequency, frequency of eating Ramyun or fast foods showed significant correlations with energy overintake indices. Stepwise regression analysis was performed to give each item a different weight by prediction strength. To determine the cut-off point of the test score, sensitivity, specificity, and positive predictive values were calculated. The 7-item checklist with test results from 0 to 13 points was developed, and those with equal or higher than 5 points were diagnosed as a risk group of energy overintake. Among our subjects 13.4% was diagnosed as the risk group. Mean energy intake of the subjects in the risk group and the normal group were 2,650 kcal and 1,640 kcal, respectively. However, there were no significant differences of Index of Nutritional Quality (INQ) of the other nutrients except eating fiber between the risk group and the normal group. This checklist will provide a useful screening tool to identify children at high risk of energy overintake.

  • The development of online funeral services and social issues of eco-friendly funeral culture have raised awareness of the new need for online funeral culture. There have been several attempts to revitalize online funeral services in domestic institutions and companies, but the effect is weak. The purpose of this study is to propose a design that can improve the accessibility and usability of online memorial services by analyzing the usability problem factors through a First Time User Experience analysis of the online memorial platform. Therefore, in this study, in order to identify the problem factors of the online memorial platform, a literature review on the UX, OOBE, and FTUE theories was conducted. The subject of the study was the app 'Memorial'. Before analyzing the First-Time User-Experience, IA was compared and analyzed with other similar services to understand the characteristics of the UX service of the app 'Memorial', which is the subject of the study. In addition, tasks corresponding to the Unpack-Setup/Configure-First Use stage were performed on 10 subjects who had no experience using the online memorial platform. The experimental process was expressed as the UX Curve to identify factors that caused negative experiences. As a result, the major problem factors included unnecessary UI elements, the need for sensitive personal information at the membership stage, and lack of immersion in the service. The improvements included strengthening community functions to facilitate the sharing of emotions and promote smooth communication between users. We proposed UI/UX service developments that enhanced the app by incorporating these insights. In order to verify the effectiveness, serviceability, and value of the developed prototype, an interview with a expert was conducted. The interviewes consisted of three service design experts. This study was conducted to contribute to the quality improvement and activation of the recently emerging online funeral services. The study is significant as it aims to understand the current status of these services and identify the factors necessary to improve service accessibility and usability. Subsequent studies require in-depth user verification of how much the proposed improvement plan affects the actual user experience.

  • The demand for electric motor fuel cells has surged in the automotive industry, leading to a recent increase in the demand for square aluminum cans used as fuel cell battery casings. The air vent located on the bottom of the rectangular battery casing prevents large explosions by intermittent pressure release prior to the accumulation of abnormally high pressures. Conventionally, the square cup battery casing is produced via six-step deep drawing, with the outer shape of the vent being manufactured by welding to the square battery casing. On the other hand, this study directly incorporated the air vent outlet into the bottom surface of the rectangular casing. The product of a coupled finite element analysis technique applying the thickness and contour generated from the square cup multi-step deep drawing formation analysis was used as the forging input shape. The results yielded increased prediction accuracy and the advanced prediction of defects, such as swelling and fracture. Based on the results of the initial analyses, two of the generated forging shapes were determined to be suitable, with the optimal forging shape being determined by molding analysis. The results presented here were validated by mold fabrication and a subsequent comparison of the actual and analytical results.

  • The extant entrepreneurship research has emphasized the development of businesses by recognizing and exploiting new opportunities rather than the development of people in organizations. To remedy this issue, scholars recently suggested the concept of humane entrepreneurship where the traditional view on entrepreneurship is enhanced by the human-centered logic. However, more scholarly work is needed to develop the concept of humane entrepreneurship as a new perspective of the entrepreneurship research domain. In this article, we attempt to enhance the research on humane entrepreneurship by suggesting its theoretical foundations and identifying the underlying dimensions of humane entrepreneurship with empirical data. This study suggests the five disciplines in management studies as theoretical foundations of humane entrepreneurship: strategic entrepreneurship, stakeholder theory, transformational leadership, motivation theory, and humanistic management. Also, we developed the measurement of humane entrepreneurship and tested its reliability and validity by collecting data from 19 countries. The results showed that the concept of humane entrepreneurship is composed of two dimensions, humane and enterprise cycles. Finally, this study provides further research agenda in the domain of humane entrepreneurship research.
