This study examined Korean and the U.S.A..'s television anti-smoking advertisements that were coined to discourage adults and teens smoking. A content analysis of 71 television advertisements listed in the "Smoking Guidance Program" operated by Korea Health Promotion Foundation. This study evaluated to detect whether the advertising content reflected core health communication theories such as health belief model, theory of reasoned action, and social cognitive theory used in the designing of anti-smoking ad message to change behavior and attitudes toward smoking unfavorably. The results showed that Korean anti-smoking ads mostly relied on social norm messages, followed by smoking attitude. The message of modeling and self-efficacy was least used; while, the U.S.A. ads focused more on modeling and self efficacy. This difference comes from the cultural difference. Namely, Korea focused more on collectivism rather than individualism. The anti-smoking ads of Korea and the U.S.A. most frequently adopted horror and humor rather than sadness, no appeal, and angry. The ads targeted more on adults rather than teens. The research identifies the types of advertisements that are most likely to utilized and underutilize in the Korea and U.S.A. anti-smoking ads and contribute to further understandings of anti-smoking ads theoretically.

For given the importance of elementary school students developing the ability to solve problems using artificial intelligence (AI), problem-solving abilities should be developed using AI along with education to develop problem-solving abilities. Such students need a form that allows them to understand the concepts and principles of AI and to be easily educated in a fun way to understand basic understanding of how AI works. To this end, this study planned an 8-hour AI convergence program and operated based on self-driving cars, demonstrating that it was effective in improving elementary school students' problem-solving abilities, creativity, and AI understanding. As a result of operating the camp, students' understanding of AI was 3.56 (standard deviation 0.85), 4.00 (standard deviation 0.71), and t-value was -5.412 (p<0.001), indicating statistically improved understanding of AI, and high satisfaction and interest of students. In the future, it will be necessary to develop an educational program that allows elementary school students to devise their own ideas and create products to which AI models can be applied.

This study surveyed on the actual conditions of using sanitizers and disinfectants for improvements of sanitization on food utensils at 105 school and 20 industry foodservice operations. The questionnaire which was administered to 125 foodservices was used as a mail or visitation method. The answers of asking "Perception on temporary authorization system of sanitizers and disinfectants on food utensils" were 75% in contract managed school foodservices, 81.8% in self operated school foodservices, and 50% in industry. Main factors to choose sanitizers were sterilizing power (38.6%, 28.6%, 38.9%) and safety (32.6%, 46.1%, 33.3%) at every foodservices. Keeping ratio of sanitizers and disinfectants guidelines in contract managed school, self operated school and industry foodservices were 64.8%, 52% and 73.7%, respectively. If easy and practical guideline is developed, most foodservices replied to use if for disinfection of foodservices. Most of the foodservices were not only knowing sanitizers and disinfectants but also possessing a guideline. However, they didn't perform disinfection according to the guideline due to its complexity. Consequently, we suggest that it is necessary to provide an easy and practical "sanitizers and disinfectants guideline" and useful information.

Objectives: This study was conducted at a request for cooperation through an analysis of the effect of toothbrushing facilities at a public health center in Seongdong-gu. Also, with the aim of furnishing basic data to the proposal of a program for improving the ability of school aged children in managing oral cavities and developing a correct toothbrushing habit, the study conducted an investigation of how toothbrushing facilities affect change in the oral environment management ability and behavior of oral health care. Methods: From among elementary schools located in Seongdong-gu, Seoul the study selected A Elementary School where toothbrushing facilities were established and have been operated since 2008, B Elementary School in an adjacent region within the jurisdiction of Seongdong-gu where the demographic environment was similar among schools where toothbrushing facilities were newly established in 2012, and C Elementary School without toothbrushing facilities. Then the study was aimed at first grade students of the schools and an investigation was carried out from April to December 2012. Through a dental checkup, the study evaluated the teeth and periodontal health conditions, and a test of the oral environment management ability was undertaken three times. Regarding change of oral health care behavior, the study carried out a self-recording survey. Results: 1. Concerning decayed and filled tooth(dft) and decayed and filled surface (dfs), A Elementary School where toothbrushing facilities have been established and operated from the past showed a relatively lower decayed, missing, and filled teeth index than B Elementary School where toothbrushing facilities were established in 2012 or C Elementary School without toothbrushing facilities; however, there was no significant difference (p>0.05). For CPI, there was no significant difference by school; however, in looking into the difference between boy students and girl students, Code (0) was discovered higher in boy students whereas Code (1) was shown higher in girl students. 2. In the PHP index test in accordance with the existence of toothbrushing facilities before the installation of toothbrushing facilities, for A Elementary School where toothbrushing facilities have been established and operated from the past, the school recorded 4.28 points whereas B Elementary School where the facilities were established in 2012 recorded 3.51 points. Meanwhile C Elementary School without the facilities posted 4.30 points. Therefore there was a statistically significant difference according to the existence of toothbrushing facilities (p<0.05). 3. In a comparison of teeth health care behavior according to the existence of toothbrushing facilities, the number of answers that the respondent did not brush their teeth after lunch over the past one week was higher in B Elementary School and C Elementary School where there were no toothbrushing facilities. Regarding the average number of brushing after lunch for one week, it was discovered higher in A Elementary School (p<0.01). 4. In change of teeth health care behavior before and after the establishment of toothbrushing facilities, the case of answering that the respondents did not brush their teeth after lunch for one week increased more after establishment than before establishment. Also the average number of teeth brushings after lunch for one week decreased further after the establishment of toothbrushing facilities; however, it did not show a significant difference (p>0.05). One of the reasons that they do not brush their teeth, "the lack of a place", decreased significantly after establishment than before establishment (p<0.05), whereas the answer, "because their friends do not brush their tooth" increased greatly after establishment than before establishment; however, there was no significant difference (p>0.05). 5. In the comparison of the degree of knowledge about dental health according to the existence of toothbrushing facilities, the degree of knowledge about dental health was shown significantly higher in A Elementary School with toothbrushing facilities than in B Elementary School and C Elementary School where there were no toothbrushing facilities (p<0.01). Conclusions: Given the above results, it is difficult to attract change in behavior only with an environmental improvement; therefore, it is deemed necessary to develop an educational program that will help children to make a habit of oral health care not only through a school but also through a related policy and financial support of government organizations as well as the construction of the basis of a systematic and consistent cooperative system with relevant organizations.

This study points out the problems of absence of the legislation for standard regulation on Video on Demand(VoD) advertisement which grows so fast lately, for this it recommends making legal references, which have the definition of non-linear broadcasting & VoD advertisement and VoD advertisement standard regulation in the merged Broadcasting Act, and adopting co-regulation system. Pay TV operators providing VoD service have the opportunities to make money as subscribers uses it increasingly. In case of linear service, the Broadcasting Act regulates the advertisement strictly, but not the VoD ads. The reason why is that Korean legislation including the Broadcasting Act does not have legal reference to regulate it, instead of that, it rely on the self-regulation system which is operated by pay-tv players who provide the VoD ads. So, there is the limitation to protect the minors such as children and youth from the harmful VoD ads, to be invulnerable for advertisers to influence to advertising agents, and to ensure the regulatory effectiveness under player-centric self-regulatory regime. In this context, this study analyses the how to regulate VoD ads standard with a three-pronged approach. First, it analyses the VoD ads regulation system in overseas countries, UK, Canada, EU and Ireland. Each country has the legal reference to regulate it in the Broadcasting Act or lower statures and adopts the co-regulatory regime the NRA and the 3rd entity operate together. Second, it reviews the objectives and scope of VoD ads standard. This study recommends that the objective of it is users protection and the scope of it is standard regulation not commercial practice. Third, this study researches how to legislate for regulation of VoD ads standard. Considering VoD service's characteristics(non-linear service) and legal position of Ads agency(i.e. pay tv operators), it suggest that legal reference will be in the integrated Broadcasting bill, which is the general law, not individual. If it is available to regulate VoD ads standard with co-regulatory regime, it expects the enhancement of user protection from the harmful VoD ads and make up sustainability of the pay-tv players' self-regulation.

The purpose of this study was to identify the preventive and the progressive inhibitory effects of enamel demineralization with fluoride releasing light-and self-cured orthodontic sealants(FluoroBond), in vitro, under the polarizing light microscope and the scanning electon microscope. The polarizing light microscopic group was subdivided into seven groups(Group A-Group G). The scanning electron microscopic group was also subdivided into seven groups(Group A'-Goup G'). For polarizing light microscopic evaluation, longitudinal sections were made longitudinally by Maruto cutter(Maruto Co., Japan) and Maruto grinding machine(Maruto Co., Japan). Sections were examined and photographed by the polarizing light microscope(Olympus Optical Co., Japan) using crossed polars and with the enamel rod longitudinal axis oriented at $45^{\circ}$ to the extinction position. For scanning electron microscopic evaluation, the specimens were coated with a highly conducting layer of gold palladium in a model Hus-4 high-vacuum evaporator and examined in an ISI-100B scanning electron microcope operated at 20kV. The results of this study were as follows : 1. The mean depths of artificial carious lesions under a polarized light microscope were $Group\;A(5.08{\mu}m),\;Group\;B(47.82{\mu}m,\;Group\;C(8.42{\mu}m),\;Group\;D(7.20{\mu}m),\;Group\;E(85.41{\mu}m),\;Group\;F(60.38{\mu}m),\;Group\;G(60.13{\mu}m)$. 2. There were statistically significant differences in Group B compared with Group A, C, and D(p<0.05), and also, in Group I compared with Group F and Group G(p<0.05). 3. Light-and self-cured orthodontic sealants had the preventive effects of enamel demineralization. 4. Light-and self-cured orthodontic sealants had the progressive inhibitory effects of enamel demineralization. 5. The time progress of demineralizing agent had no influence on the samples of light-and self-cured orthodontic sealants under the scanning electron microscope. 6. There was no difference between the specimens of light-and self-cured orthodontic sealants both in the polarized light microscopic group and in the scanning electron microscopic group.

As the foodservice industry is labor intensive, the efficient management of human resources is an essential element for improving operational efficiency. This study was designed to investigate the performance level of human resource management in self-operated school foodservices and to examine the relationship between human resource management, organizational commitment, and productivity. Whether these factors rated differently by employment and job types was also examined. Data were collected through questionnaires distributed to 60 dieticians and 240 cooks in Seongnam and Yongin. Frequency analysis, factor analysis, the t-test and multiple regression analysis were tested using Minitab. Human resource management practices rated highly in the dimension of employee training (3.51), followed by working environment (3.39), and turnover management (3.37). In contrast, reward management (1.73) and working condition (1.56) received the lowest score. Organizational commitment scored 3.65 points, and showed that dedication (3.82) was the highest score; however, self-esteem (3.50) was the lowest score. For human resource management, there were significant differences between employment types as full time workers (3.85) rated management more highly than part-time worker (3.43). Overall productivity was fairly high, especially in high school foodservices. Only the performance appraisal had an influence on organizational commitment (${\beta}$=0.292, P<0.05). Productivity was positively correlated with human resource management (r=0.432, P<0.001) and organizational commitment (r=0.36, P<0.01). In conclusion, school foodservices need to establish objective performance standards, and increase employee morale by enhancing reward systems and working conditions. In particular, irregular employees require training with job performance standards and given a proper reward program, depending on their performance, to improve organizational commitment.

This study tried to explore the ways to operate service learning more effectively by analyzing the educational effects of service learning and changes in learning sentiments that appeared in the service learning operation process established for the realization of the Christian educational philosophy at a small local Christian university. The analysis was conducted using NVivo11, focusing on the reflection journals of students who participated in service learning in the first semester of 2022 at J University. As a result of the study, through service learning, personal competence growth, self-reflection and will to change, self-esteem and self-efficacy, social and civic aspects, social responsibility enhancement, community (community) empathy and awareness of participation, and helping others There were educational effects such as an increase in the breadth of understanding. In addition, learning emotions that appeared in the service learning process included positive emotions such as gratitude, challenge recognition, pride, confidence, and responsibility, and negative emotions such as worry (difficulty), upset, regret, and awkwardness. It is a measure to increase the educational effect based on the learning emotion shown in the service learning process. When operating service learning, the service period at the visiting institution is increased to 6 weeks or more, and based on close interaction and detailed analysis of the educational environment in the planning stage, Suggest to develop and operate a plan. In addition, if you have the opportunity to receive feedback from your professors and colleagues through demonstrations and mock presentations in the classroom before visiting the institution, and finally have the opportunity to visit the institution again after the results of service learning are announced, more quality service learning education will be operated. Based on the results of this study, it is expected that more valuable and meaningful service learning education opportunities will be provided to learners by designing and operating a practical and sophisticated service learning curriculum.

This study analyzed the effect of the entrepreneurship planning course provided by an women's university in Seoul on the enhancement of the core competencies of entrepreneurship of university students. To this end, pre- and post-test of core entrepreneurship competency were conducted on 63 female university students (32 in experimental group, 31 in control group) and then the results were analyzed. The course in which the experimental group participated was a team-based project learning course and it required a team of three people to draw an entrepreneurship plan containing social problem solving as the final result. The course was operated for a total of 8 weeks. To measure the level of entrepreneurship core competency in the pre- and post- test, the survey tool that was developed by the Ministry of Education and Korea Entrepreneurship Foundation (2020) was used. This tool composed by 'value creation', 'challenge', 'self-directed', and 'group creativity' competencies. As analyses methods, i) covariance analysis was performed using the pretest as a covariate, and then a two-way ANOVA was performed with treatment (experimental group, control group) and time point (pre test, post test) as two independent variables. Results show while there was no significant difference between the experimental group and the control group in the value creation competency, it significantly contributed to the enhancement of challenge, self-directed, and collective creativity competencies. Based on these results, implications and limitations were discussed, followed by future research direction.
