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.

Word templates exist for select journals, and their primary objective is to facilitate submissions to those journals, thereby optimizing editors' and publishers' time and resources by ensuring that the desired style (e.g., of sections, references, etc.) is followed. However, if multiple unrelated authors use the exact same template, a risk exists that some text might be erroneously cloned if template-based papers are not carefully screened by authors, journal editors or proof copyeditors. Elsevier Procedia® was used as an example. Select cloned text, presumably derived from MS Word templates used for submissions to Elsevier Procedia® journals, was assessed using Science Direct. Typically, in academic publishing, identical text is screened using text similarity software during the submission process, and if detected, may be flagged as plagiarism. After searching for "heading should be left justified, bold, with the first letter capitalized", 44 Elsevier Procedia® papers were found to be positive for vestigial template text. The integrity of the information in these papers has been compromised, so these errors should be corrected with an erratum, or in the case of extensive errors and vast tracts (e.g., pages long) of template text, papers should be retracted and republished.

Purpose: This study aims to determine the status of dental technician's continuing education and licensing reporting and provide basic data that can aid in improving the operation of progressive continuing education and licensing reporting and development programs. Methods: This study included dental technicians nationwide who attended the 2023 Korea Dental Technology Expo & Scientific Conference and responded to an online survey from July 21 to July 23, 2023. In total, 180 copies were analyzed. The reliability of satisfaction with continuing education demonstrated a Cronbach's α of 0.924. IBM SPSS Statistics version 21.0 (IBM) was used to statistically analyze the collected data. Results: Satisfaction with continuing education for dental technicians was 2.78, 2.81, 3.21, 2.96, and 2.87 for the number of lectures offered, composition of major fields, lecture content, instructor level, and overall satisfaction, respectively. The average satisfaction with continuing education was 2.93, which was lower than the average (3 points). The investigation revealed that overall improvement was required. Conclusion: Measures for those who have not completed continuing education must be implemented within the government's legal influence by actively using the license reporting system. Strengthening verification of completion of continuing education, improving autonomous disciplinary rights, diversifying the content and learning methods of continuing education, linking with the license reporting system, improving institutional postevaluation, and introducing related policies should be conducted when opening a dental laboratory.

The introduction of bio-based materials has been recommended in the geotechnical engineering field to reduce environmental pollutants such as heavy metals and greenhouse gases. However, bio-treated soil methods face limitations in field application due to short research periods and insufficient verification of engineering performance, especially when compared to conventional materials like cement. Therefore, this study aimed to develop a machine learning model for predicting the unconfined compressive strength, a representative soil property, of biopolymer-based soil treatment (BPST). Four machine learning algorithms were compared to determine a suitable model, including linear regression (LR), support vector regression (SVR), random forest (RF), and neural network (NN). Except for LR, the SVR, RF, and NN algorithms exhibited high predictive performance with an R² value of 0.98 or higher. The permutation feature importance technique was used to identify the main factors affecting the strength enhancement of BPST. The results indicated that the unconfined compressive strength of BPST is affected by mean particle size, followed by biopolymer content and water content. With a reliable prediction model, the proposed model can present guidelines prior to laboratory testing and field application, thereby saving a significant amount of time and money.

The study examined perception of library personnel towards social media utilization for information service delivery in kwara state university library. It adopted the descriptive survey design with population consisting of 27 professional librarians in three selected university libraries in kwara State. Total enumerative sampling techniques were used because the population of the study is manageable by the researcher. Percentage and mean were used in analyzing the data. Primary data solicited would be cleaned, coded and entered into the Statistical Package for Social Sciences (SPSS) version 20 software for quantitative analysis. The findings of the study revealed the services rendered by library professional in university libraries in Kwara State, are Current Awareness Services (CAS), Photocopying services, Technical Services, Circulation/borrowing services, Internet services, and Bibliographic verification services. Majority of the respondent indicated Myspace, Google plus, Flickr, Telegram, Twitter, WhatsApp and Facebook are the social media platforms used for service delivery by librarians. Also, majority of the respondents in university libraries indicated Google plus, LinkedIn, Myspace, Skype, WhatsApp, Flickr, WeChat, Twitter and Facebook as social media space use for information service delivery effectively and Bandwidth problem, Limited fund, Lack of maintenance culture, Lack of Awareness, Copyright Issue, Technophobia are the major challenges inhibiting the use of social media for service delivery by the library staff. Lastly, the study concluded with recommendations.

Purpose: This study was done to develop a cell phone addiction scale for Korean adolescents. Methods: The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 577 adolescents in two middle schools and three high schools. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data. Results: Twenty items were selected for the final scale, and categorized into 3 factors explaining 55.45% of total variance. The factors were labeled as withdrawal/tolerance (7 items), life dysfunction (6 items), and compulsion/persistence (7 items). The scores for the scale were significantly correlated with self-control, impulsiveness, and cell phone use. Cronbach's alpha coefficient for the 20 items was .92. Scale scores identified students as cell phone addicted, heavy users, or average users. Conclusion: The above findings indicate that the cell phone addiction scale has good validity and reliability when used with Korean adolescents.

In this paper, we have studied scale tools for measure programming task value and learning persistence at elementary school students. In order to develop complete test tools, we have improved the completeness by revising tests through stepwise verification. The first scales were constructed based on the previous studies. As a result of the content validity test, 5 out of 14 items of the task value test tool and 1 out of 10 items of the learning persistence test were not suitable. The second test tools were constructed by revising and supplementing the first scale, and consisted of 13 items of task value and 8 items of learning persistence. As a result of the contents validity test, all the items included in the test tool proved to be valid. The reliability of the secondary testing tools were also found to be reliable at ${\alpha}=.970$ and ${\alpha}=.975$, respectively.
