This study aims to design mathematics-integrated classes that cultivate artificial intelligence (AI) thinking and to analyze students' AI thinking within these classes. To do this, four classes were designed through the integration of the AI4K12 Initiative's AI Big Ideas with the 2015 revised elementary mathematics curriculum. Implementation of three classes took place with 5th and 6th grade elementary school students. Leveraging the computational thinking taxonomy and the AI thinking components, a comprehensive framework for analyzing of AI thinking was established. Using this framework, analysis of students' AI thinking during these classes was conducted based on classroom discourse and supplementary worksheets. The results of the analysis were peer-reviewed by two researchers. The research findings affirm the potential of mathematics-integrated classes in nurturing students' AI thinking and underscore the viability of AI education for elementary school students. The classes, based on AI Big Ideas, facilitated elementary students' understanding of AI concepts and principles, enhanced their grasp of mathematical content elements, and reinforced mathematical process aspects. Furthermore, through activities that maintain structural consistency with previous problem-solving methods while applying them to new problems, the potential for the transfer of AI thinking was evidenced.

Purpose: The purpose was to examine the effectiveness of a psychosocial stress management program on stress and coping in student nurses. Method: A nonequivalent control group pre-posttest design was used. A convenience sample of 24 students from the Department of Nursing, Wonju College of Medicine, Yonsei University were assigned to experimental (n=12) and control groups(n=12). Stress was measured using the Visual Analog Scale (10 points) and blood cortisol. Coping was measured using a scale modified by So (1995) based on the Ways of Coping Checklist developed by Folkman and Lazarus (1985). Depression was measured using the CES-D by Radloff (1977) and state anxiety, using the State Anxiety Inventory by Spielberger (1976). The psychosocial stress management program included education, relaxation (Korean Dan Jeon-typed Breathing and music), and social support. Result: Results showed for the two groups, 1) a significant difference in stress scores (U= 19.50, p=0.002), 2) no difference in cortisol levels (8am, 4pm), 3) a significant difference in problem-focused coping (U=25.50, =0.007), 4) no difference in emotion-focused coping, and 5) no difference in state anxiety and depression. Conclusion: By utilizing the program, students were able to learn how to control their stress and improve their coping. Therefore with a partial modification, psychosocial stress management can be useful for continual management of stress in student nurses.

The purpose of this study is to suggest a pedagogic direction of home economics education that can form body image which organize self-concept of adolescents positively. To achieve this purpose, the study suggested a body image formation model of adolescents that can be applied to home economics education, and based on this formation model, analyzed contents on body image of current 12 textbooks of home economics education. The main results of this study are summarized as follows: First, to analyze textbook through body image formation model of adolescents, educational contents about body image were categorized into 4 constructs with 8 sub-categories. Second, we found the current textbooks about the child and family life field, food and dietary life field, and clothing life, are handling topics regarding body image formation model of adolescents, such as concepts and components of body image and antecedents and outcomes of body image. We conclude that although the current textbooks handles contents on body image of adolescents, those contents are sporadically presented across the three fields without an integrated perspective. Home Economics, as an entity of educating adolescents' self-esteem through daily life activities, needs to have a topic-oriented approach in developing a curriculum.
Contamination levels of aerobic colony counts, coliforms and pathogenic bacteria were tested in fried rice dishes to monitor quality for risk management. The prevalence of Bacillus cereus in dishes from 8 Chinese-style restaurants and 2 institutional foodservices was 10%, and the bacteria's contamination levels was 3.47 log CFU/g. Echerichia coli, Staphylococcus aureus, and Salmonella were not detected in any of the 10 samples. However, for their aerobic colony counts and numbers of isolated coliforms, the samples were 30% and 70% over the microbial criteria, respectively, for ready-to-eat foods presented in the Korean Food Code. This suggests that fried rice dishes, although cooked with oil at high temperature, require special care. For the prediction of the growth curve of B. cereus spp. in the fried rice samples, an experiment design of 3 storage temperatures ($7^{\circ}C$, $35^{\circ}C$, $57^{\circ}C$) x 5 storage times (0 h, 2 h, 4 h, 6 h, 24 h) was applied. The sample exposed to $35^{\circ}C$ showed no B. cereus spp. at 0 h; however, there was a tendency of slow growth (1.0 log CFU/g) after 4 hours of storage and then faster growth at 6 h (3.7 log CFU/g) and 12 h (4.7 log CFU/g), showing a growth rate of 0.56 log CFU/g/hr. These results indicate that fried rice, despite being heat-treated, can become heavily contaminated with B. cereus spp. when held over 2 hours at room temperature. However, the samples stored at $7^{\circ}C$ and $57^{\circ}C$ over 24 hours were not contaminated with B. cereus. Based on these results, management guidelines for controlling B. cereus are suggested.
The purpose of this study was to determine the impact of situational, clinical and psychsoical factors on treatment-seeking behavior among those with acute myocardial infarction(AMI). This study used a retrospective, descriptive design. The sample consisted of 72 patients aged over 30 and who were diagnosed with an acute myocardial infarction at two large university-affiliated medical centers from July 1, 1998 to March 30, 2000. But of 72, patients 5 who were an outlier in treatment-seeking time were deleted. Data were collected by using questionnaires, which included demographic data, situational, clinical and psychosocial data. Also patient interviews and chart review were used to obtain information related to treatment-seeking time. The results of this study were summarized as follows ; 1. Mean time from the onset of AMI symptoms to arrival at the hospital was $12.09{\pm}11.44$ hours; 2. Treatment-seeking time was not significantly different by age, gender, or education; 3. Most(44 or 65.78%) patients were at home when they began having AMI symptoms. The remaining patients were either in a public area, workplace or in a car. Patients at home delayed longer than those who had their first symptoms elsewhere, but not significantly different. Also, most patients were with another person when they began to experience AMI symptoms: a spouse(25 or 37.3%), other family member(31 or 46.3%); the remaining 11 were alone. There were no significant differences in treatment-seeking time based on whether alone or with others. Most patients(46 or 68.7%) used an ambulance rather than taking private transportation, and patients who used an ambulance were delayed longer than those who used private transportation, but there were no significant differences; 4. Time to treatment-seeking was not significantly different by blood pressure, heart rate on admission and the peak CK-MB, CPK and Cholesterol level, Killips class; 5. There were no significant statistical differences in treament-seeking times by anxiety level, mood status or control ability.
The objective of this study was to identify the current status of use and respective work scopes of dental hygienists and nursing assistants as perceived by dentists, thereby obtaining a model for how to efficiently use oral health assistance personnel. This study was based on a self-reported survey administered to a total of 126 dentists. The following findings were observed. Where competition among neighborhood clinics was relatively high, nursing assistants tended to be used as a resource to assist dental hygienists, whereas where it was relatively low, they were more likely to be considered to work as full substitutes for regular dental hygienists. Looking at the scopes of practice, dental hygienists were allowed to deal with matters of preventive care, oral health education, and health insurance claims. On the other hand, nursing assistants were allowed to be in charge of taking X-ray pictures from the outside and inside of mouth and keeping medical devices clean and safe. This study is expected to contribute to establishing more reasonable oral heath personnel structure design decisions.
Purpose - Franchise industries are significant both socially and economically. However, with increasing interest, there are manifold problems. It is necessary to seek measures for mature operation constantly despite unprepared franchisors, negative perceptions of the media and society toward franchise, and rapid changes in business start-up trends and propensity to consume that make business start-ups difficult. The paper aims to explain the effects of relational commitment and performance on the franchisor's management characteristics and justice in the food service franchise system. Research design, data, and methodology - This is an exploratory survey examining franchising in Korea. Based on a literature synthesis, we extract five constructs: managerial characteristics, support, fairness, trust, and satisfaction. We hypothesize that these factors influence the trust, satisfaction, and performance of franchisees. To examine these hypotheses empirically, we conducted a survey on the database of the Franchising Council of Korea. The study employs data from May to September 2014. In total, 135 completed questionnaires were received, of which 128 were usable. The data was analyzed with SPSS/PC 22.0. First, to test unidimensionality and nomological validity of the measures of each construct, we employed a scale refinement procedure. The result of a reliability test with Cronbach's α and factor analysis warranted unidimensionality of the measures for each construct. In addition, nomological validity of the measures was warranted from the result of the correlation and regression analysis. By analyzing the data, we can confirm most hypotheses. Results - Frist, franchisor characteristics have a positive effect on trust and satisfaction. Second, franchisor fairness has an effect on trust and satisfaction. Third, franchisor support has an effect on satisfaction. Further, the franchisee trust has an effect on satisfaction. Fourth, the satisfaction of a franchisee with a franchisor affects the performance of a franchisee. Finally, there is a possibility that not only franchisee performance but also increasing the credibility and improving the image of the franchisor through communication between franchisor and franchisee can improve franchisees' performance and satisfaction by motivating the franchisee for sustainable growth. Franchisers should endeavor for franchisees to obtain stable revenue with continuous and practical support. They should recognize that they can expand their business by supporting their franchisees. Franchisors should not only instantly respond to franchisees' troubles with interactive communications but also raise the ability of supervisors for better support. Franchisors should share their visions and goals with their franchisees and provide systematic and continuous support based on trust and clear company management. Franchisees should understand franchisors' position as well as participate in establishing the basic franchise system. Contributions - The paper contributes to understanding franchising in Korea. It offers insights and assistance to franchisors hoping to start franchises. This paper explores measurement issues related to franchisee performance by estimating its determinant factors (managerial characteristics, support, fairness, trust, and satisfaction). This study provides franchisors and practitioners planning to extend their franchising business with some practical knowledge.
The university must open the "School Development Plan and Specialization Plan" at the university allimi. The reason for this is the Special Act on the Disclosure of Information by Educational Institutions, enacted on May 25, 2007, and the Plan for Reform of University Reform announced by the Ministry of Education on Mar 28, 2014. Therefore, we examined the similarity and standardized model of the "School Development Plan and Specialization Plan" published by a total of 137 colleges. As a result of the study, only 17(12.4%) of the college produced information in two ways(school development and specialization), and the rest were not. The school development plan presented quantitative indicators such as world number one, The characterization plan presented qualitative indicators such as human. Based on this, standardized research procedures and conception are presented.
