Recently, domestic schools are increasingly interested in environmental education related to COVID-19 and the severe climate crisis, as well as artificial intelligence education related to the 4th industrial revolution that is rapidly approaching us. In particular, AI education is highly likely to be applied to 5th to 6th graders of elementary school, so measures related to connection with 1st to 4th graders are needed. There are many students who are not proficient in computers in the lower grades of elementary school, so there may be many restrictions in using the currently used teaching aids. Therefore, this study tried to develop an artificial intelligence education program for the lower grades of elementary school to secure the linkage of artificial intelligence education. The theme of the program was developed based on the topic of environmental education, which has recently increased in interest. As for the educational method, considering the developmental stage of the lower grades of elementary school, the STEAM education method was used, which was fused with various subjects and unplugged using play and games without a computer. of the program. For validity verification, Lawshe (1975)'s content validity ratio (CVR) calculation formula was used. The verification results were analyzed to be suitable for the purpose of development of all programs. In the future, it is necessary to measure the degree of effectiveness by applying the program proposed in this study to the lower grades of elementary school.

This study tried to develop a lifestyle redesign program that can be applied to college students. For program development, the Delphi research method was implemented with 8 experts. Based on previous studies on lifestyle and time use, the first Delphi survey investigated the prioritization of occupations through evaluation instruments, lifestyle types, and living time survey tables. In the second Delphi survey, it was constructed based on the opinions of experts, and when the content validity ratio was low, it was reconstructed by modifying and supplementing it. In the third Delphi survey, while maintaining the framework of the secondary content, the experts' own responses from the second time and the second average score with other experts were presented together. As a result of this study, a program with an average score of 3.88~4.00, a content validity ratio of 1.00, and a convergence of 0.00 was finally derived. In the lifestyle redesign program for college students, the first step of the pre-intervention evaluation is to identify the lifestyle type, apply evaluation tools, and select occupations. In the second step, the lifestyle is redesigned by the intervention execution, and the facilitator intervenes to help college students do well their tasks. The program was developed by encouraging them to practice, checking the lifestyle type change as a result of the intervention in step 3, applying evaluation instruments after the intervention, and ending the program in the last step. This study provided a rationale for using lifestyle redesign program as an intervention to change their occupational performance patterns in order to successfully carry out the life they want.
Background: Given that there are many Iranian women who have never had a Pap smear, this study was designed to develop and validate a measurement tool based on the Protection Motivation Theory to assess factors influencing the Iranian women's intention to perform first Pap testing. Materials and Methods: In this psychometric research, to determine the Content Validity Index (CVI) and the Content Validity Ratio (CVR), a panel of experts (n=10) reviewed scale items. Reliability was estimated through the Intraclass Correlation Coefficient (n=30) and internal consistency (n=240). Also, factor analysis (exploratory and conformity) was performed on the data of the sample women who had never had a Pap smear test (n=240). Results: A 26-item questionnaire was developed. The CVI and CVR scores of the scale were 0.89 and 0.90, respectively. Exploratory factor analysis loaded a 26-item with seven factors questionnaire (perceived vulnerability and severity, fear, response costs, response efficacy, self-efficacy, and protection motivation (or intention)) that jointly accounted for 72.76% of the observed variance. Confirmatory factor analysis indicated a good fit for the data. Internal consistency (range 0.70-0.93) and test-retest reliability (range 0.72-0.96) of sub-scales were acceptable. Conclusions: This study showed that the designed instrument was a valid and reliable tool for measuring the factors influencing the women's intention to perform their first Pap testing.
Purpose: There has been a growing recognition that person-centered care enhances the quality of life of nursing home residents with dementia. This study was conducted to develop a person-centered dementia care online education program for direct care staff in long-term care facilities. Methods: Delphi method with expert group was used to validate contents. We developed 61 draft items based on literature review. Twenty experts participated in consecutive three round surveys including 5-point Likert scale questions and open-ended questions. Based on experts' opinions, the content validity ratio for content validity and the coefficient of variation for stability were calculated. Results: Three-round Delphi surveys and additional feedback from the expert panel established a consensus of core contents: 1) dementia (7 categories), 2) person-centered care (6 categories), 3) communication (8 categories), and 4) behavioral and psychological symptoms of dementia (6 categories). Specific sub-categories in each category were differentiated according to the job qualifications (65 sub-categories for registered nurses, 64 sub-categories for nursing aids, and 41 sub-categories for personal care workers). Conclusion: This delphi study identified person-centered dementia education curricula, in which the person-centered approach should be a key policy priority in Korean long-term care system. Now it is urgently needed to develop education programs utilizing online platforms that enable efficient and continuous learning for long-term care staff, which can contribute to behavior changes in the person-centered dementia care approach and improvement of care quality in long-term care facilities.

In this study, the Delphi method and AHP (analytic hierarchy process) were used to evaluate tunnel collapse risk from a comprehensive and multifaceted perspective. Influence factors were established through literature reviews, previous studies, and brainstorming sessions with expert groups, resulting in the construction of five main classification systems. A panel of 21 experts was formed, and three rounds of Delphi surveys were conducted to prevent errors and biases in the expert judgment process, thereby enhancing reliability. Ultimately, 14 influence factors were identified through CVR (content validity ratio) and COV (coefficient of variation) analyses of the experts' responses. Subsequently, the AHP method was applied to assess the relative importance of each influence factor and calculate the final composite weights. The timing of support and reinforcement had the highest priority, followed by groundwater inflow, joint conditions, support pattern levels, and auxiliary methods. These findings help identify the key factors affecting tunnel collapse risk and provide a foundation for developing strategies to improve tunnel safety.
Purpose: This study was conducted to develop, validate, and assess the reliability of a questionnaire for nutritional literacy among young Korean adults. Methods: The draft questionnaire contained 65 items in 7 domains (i.e., dietary guideline, nutrition and health, nutrients, 5 food groups [food bicycle], nutrition labeling, portion size, and nutrition management for disease prevention). The authors developed a draft questionnaire based on a literature review. After multiple drafts, 52 items were retained and 13 were eliminated in the 7 domains according to professional advice from 5 nutrition experts. A panel of experts (n = 20) comprised of clinical dietitians and nutrition professors completed the content validity assessment, including quantitative and qualitative feedback. As the results, all items of the portion size were eliminated from the questionnaire. A sample of 211 young adults completed the test-retest reliability assessment. Test-retest reliability was evaluated using intra-class correlation coefficient (ICC) and inter-item reliability by Cronbach α coefficient. Results: The final questionnaire contained 30 items with 5 questions each on the dietary guideline, nutrition and health, nutrients, 5 food groups (food bicycle), nutrition labeling, and nutrition management for disease prevention. The Lawshe content validity ratio for domains ranged from 0.60 to 1.00. The ICC scores for questions ranged from 0.64 to 0.86. Cronbach's α for domains ranged from 0.83 to 0.90 and for the overall questionnaire was 0.87. Conclusion: The questionnaire showed strong content validity, test-retest reliability, and high inter-item reliability, indicating that it is a useful tool for assessing nutritional literacy of young adults.
Objectives: Maintaining a balanced diet is very crucial for adolescents. However, adolescents, who may have a short notion about the amount of food, find it difficult to plan daily meals by applying the target pattern proposed by the Korean Nutrition Society. This study was carried out to revise the target pattern based on cooked dishes instead of raw material food groups as an easier way for Korean adolescents to plan their meals. Methods: Target pattern for Korean adolescents were revised based on the following: $1^{st}$, categorize dish groups, $2^{nd}$, calculate representative values of each dish based on the adolescent' intake amount. $3^{rd}$, assign the recommended number of intake for each dish. Validity of the target pattern for Korean adolescent meal plan was examined by the energy content, energy contribution ratio, and NAR & INQ of nutrients. Results: The 11 dish groups categorized were bab; gook tang gigae; side dishes of meat, fish, egg, legume, kimchi, vegetable, seaweed; and between meal of fruit, and milk dairy product. Based on the representative energy values, recommended number of intake were assigned to each dish. For boys, bab and gook tang gigae: 3 each; meat, fish, egg, and legume: 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk dairy product: 2 each were assigned. For girls, bab and gook tang gigae: 2 each; meat, fish, egg, and legume: choice of 3 dishes, 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk dairy product: 2 each were assigned. Energy contents, energy contribution ratio of carbohydrate, protein, and fat for boys and girls were in adequate range. The NARs were 1.0 and INQs were ${\geq}1.0$ for all nutrients examined. Conclusions: Revised dish-based, instead of food-based adolescent target patterns for boys and girls were easier and a valid way of Korean adolescent meal planning.
Purposes: The purpose is to establish the direction of healthcare R&D through private nonprofit organization. Methodology: The data is divided into two groups: 12 physicians and pharmacists, and 16 persons including professors related to university donation, non-profit foundation executives. Each group was subjected to two Delphi surveys. To analyze the validity of the opinion, the content validity ratio and the consensus of experts were verified. Findings: Funding should be invested in 'development research' and 'application research'. The factors that hinder the donation culture are 'donation prevention system such as tax imposition system and rebate double penalty system', 'insufficient motivation of fund raising person', and 'lack of fund specializing specialist'. The fund raising strategy should be centered on a small number of large donors or a balance between large and small donors. The fund raising target should be effective to raise funds for corporate and individual donors. It is necessary to clarify the purpose of the social problem to be solved by the campaign strategy for promoting donation, to announce the validity of the trust and transparency of the institution, and to emphasize the social investment by the private sector. Practical Implications: It is necessary to present directions through private nonprofit organizations for the future development of healthcare R&D. The legal and institutional deficiencies of the domestic nonprofit organization fundraising infrastructure should be improved. In order to create a social investment climate, it is necessary to improve the awareness of donations and develop various donation programs for the private sector.
