Purpose: This protocol aims to improve the simplicity of the existing two-person cardiopulmonary resuscitation (CPR) by focusing on chest compressions and artificial respiration, and classifying the roles within the scope that can be observed. Methods: In this study, the protocol was developed by forming an expert group consisting of a professor from the emergency and rescue department, a professor from the nursing department, and a first aid officer from the fire department. In addition, if the number of panels is 15 and the derived content validity ratio (CVR) value exceeds 0.49, a reference point that satisfies content validity at 95% reliability is presented. Results: All 11 performance items exceeded the CVR value of 0.49 to meet the reference point, and the CVR range of this protocol is 0.625 to 1.000. Conclusion: In order to improve the quality of three-person CPR, verification of simulation models and continuous protocol revision should be conducted by individuals specializing in various fields.

Purpose: This study verified the reliability and validity of the Diet Quality Index for Indian children (DQIIC). Methods: The study sample included 100 school going boys and girls (7-9 years). The dietary behavior of children was studied using a questionnaire and 24-hour dietary recall. The DQIIC comprises 21 items which aimed to assess the diet of Indian children on the basis of variety, adequacy of consumption of dietary components, and moderation in the amount of nutrients that are associated with diseases and dietary habits. The reliability of the DQIIC was assessed using the split half method, Cronbach's alpha, and test retest reliability. Content validity was evaluated using content validity ratio (CVR). Results: The intake of iron was found to be less than the recommended dietary allowances. There was frequent consumption of empty calorie packaged foods and higher than the recommended amount of sodium. Reliability of the DQIIC was 0.85 by split half method and the correlation coefficient for test retest reliability was 0.87. Cronbach's alpha was 0.62 and CVR was 0.85 for this index. Most of the children fell in the moderately healthy category. Conclusion: The DQIIC is a reliable and valid tool to assess the diet quality of Indian children between 7-9 years.

2005년 정부가 첫 해양교육 정책인 「청소년 해양교육계획(2005~2010)」을 발표한지 16년이 지났다. 정부의 노력으로 해양교육 중요성에 대한 국민의 공감대는 형성되었지만, 그동안 수립한 정책이 국민을 비롯해 사회경제에 미친 영향을 객관적으로 분석하지는 못하였다. 따라서 본 연구는 해양교육 서비스에 개인들이 부여하는 가치의 정확한 정의와 측정 지표를 개발함으로써 해양교육 참여집단과 비참여집단 간 해양에 대한 인식과 행동의 차이를 파악하고 해양교육의 효용성을 분석하고자 하였다. 이를 위하여 첫째, 해양교육의 가치를 정의하고 국민 개인에게 제공할 수 있는 가치 항목에 대해 분류하였다. 둘째, 분류된 가치 항목들을 측정할 수 있는 지표 개발을 위해 다양한 전문가의 의견을 수렴할 수 있는 델파이조사를 실시하였다. 셋째, 각 항목별 내용타당도(Content Validity Ratio, CVR)를 측정하여 최종 지표와 설문 문항을 도출하였다. 전문가 델파이 분석 결과 32개의 지표 항목 중 CVR값 0.6 이상인 18개의 항목이 최종 채택되었다. 인지적 가치 범주에는 개인의 해양 지식 수준과 인식 변화, 문제해결 역량 등을 파악할 수 있는 지표들이 선정되었으며, 행동적 가치 범주에는 좀 더 구체적으로 해양을 바라보는 태도와 관계, 책임감 있는 행동 변화를 판단할 수 있도록 지표로 확장하였다. 본 연구는 정부가 국민에게 제공하는 해양교육서비스의 가치를 직접적으로 판단할 수 있는 근거를 제시한다는 점에서 의미를 가진다. 이와 같은 분석 결과들은 정부가 해양교육 정책을 지속적으로 추진하는데 있어 안정적인 예산 확보 및 인적자원 확대의 당위성을 확보하는데 기여할 것으로 기대한다.

In traditional programing education, computers were used as the main tool. Consequently, it was problematic to provide education in an environment without computers or for learners without computer skills. To address this problem, this study developed and validated an unplugged robot education system capable of computerless programming education. The key feature of the proposed system is that programing can be done only by connecting programming blocks in symbols of a flow chart with built-in commands. Validation of the system was performed by a specialist group. Validity was very high with values of content validity ratio (CVR) over 0.7 in all evaluation criteria except "Ease of error debugging" and "Linkages to educational curriculum," whose CVR values were each 0.6. Future directions include improvement in the two areas that scored lower than the others did by, respectively, system improvement to support debugging in error conditions that may occur during the programming process, and development of user guide to support linkages to educational curriculum.

Purpose: The purpose of this study was to verify the validity and reliability of the Korean version of the Pain in Older Adults Knowledge Survey (K-POAKS) to assess knowledge of pain in older adults including people with dementia for use in long-term care hospital nurses. Methods: Survey data were collected from a convenience sample of 179 nurses who have worked in long-term care hospitals in B, D and U cities. The Kuder-Richardson Formula 20 for internal consistency for test reliability was conducted. The content, criterion-related and construct validity were evaluated using SPSS/WIN 22.0. Results: The KR 20 was .75 and Content Validity Ratio (CVR) was a range of 0.84~1.00. The criterion-related validity was positively correlated with attitudes (r=.28, p<.001) and performance (r=.21, p=.004). The construct validity of K-POAKS was analyzed by conducting the principal component method using the exploratory factor analysis varimax rotation, and seven factors were derived above the eigenvalue of 1.0. The seven factors explained 58.5% of the total variation. Conclusion: The Korean version of the POAKS showed satisfactory internal reliability, content validity, criterion-related validity and construct validity. These results suggest that the K-POAKS could be used as a suitable tool to measure the knowledge of the aged people's pain, including that of dementia patients for long-term care hospital nurses.

Purpose: This study aimed to describe the process of developing a validated pediatric nursing simulation scenario template using the real-time Delphi method. Methods: A panel of 13 pediatric nursing experts participated in a real-time Delphi survey conducted over two rounds. Initially, 83 items were included in the questionnaire focusing on the structure and content of the simulation scenario template. Data analysis involved calculating the content validity ratio (CVR) and the coefficient of variation to assess item validity and stability. Results: Through iterative rounds of the Delphi survey, a consensus was reached among the experts, resulting in the development of a pediatric nursing simulation scenario template comprising 41 items across nine parts. The CVR values ranged from 0.85 to 1.0, indicating a high consensus among experts regarding the inclusion of all items in the template. Conclusion: This study presents a novel approach for developing a pediatric nursing simulation scenario template using real-time Delphi methods. The real-time Delphi method facilitated the development of a comprehensive and scientifically grounded pediatric nursing simulation scenario template. Our template aligns with the International Nursing Association for Clinical Simulation and Learning standards, and provides valuable guidance for educators in designing effective simulation scenarios, contributing to enhanced learning outcomes and better preparation for pediatric clinical practice. However, consideration of cultural and contextual adaptations is necessary, and further research should explore alternative consensus criteria.

Purpose: The purpose of this study was to evaluate the psychometric properties of the Korean version of the Alzheimer's Disease Knowledge Scale (ADKS-K) to determine its applicability to Korean adults. Methods: Cross-cultural validity was performed according to Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN). The Kuder-Richardson Formula 20 for internal consistency and Intraclass Correlation Coefficient (ICC) for test-retest reliability were conducted. Content validity, criterion related validity and construct validity were evaluated. The Classical Test Theory (CTT) model and the Item Response Theory (IRT) model were applied in performing the item analysis. Results: The KR 20 was .71, and the ICC was .90, indicating that the ADKS-K has internal consistency and stability reliability. Thirty items of the ADKS-K had significant Content Validity Ratio (CVR) values, i.e., mean of 0.82 and range of 0.60~1.00. Mean item difficulty and discrimination indices calculated by TestAn program were 0.63 and 0.23, respectively. Mean item difficulty and discrimination indices calculated by BayesiAn program were -0.60 and 0.77, respectively. These tests indicate that ADKS-K has an acceptable level of difficulty and discriminating efficiency. Conclusion: Results suggest that ADKS-K has the potential to be a proper instrument for assessing AD knowledge in Korean adults.
