The purpose of this study was to develop and investigate the validity and reliability of the Korean Version of Nurse's Job Crafting Scale. The Korean version of Job Crafting was translated and reverse-translated, and its content validity was verified by experts. Statistics were processed using SPSS/WIN 21.0 and AMOS 21.0 programs through self-report questionnaires for 151 nurses. Exploratory factor analysis and confirmatory actor analysis were performed to verify construct validity, and model fit, concentrated validity, and discriminant validity were confirmed through the analysis results.To verify the criterion validity, correlations with each domain were obtained using the calling scale. For reliability verification, the internal consistency reliability coefficient was calculated and confirmed. Reliability of all 20 job crafting tools was Cronbach's α = .93, with .91 for factor 1 (Increase in structural work resources, 5 questions) and .87 for factor 2 (Increase in structural work resources, 5 questions). The factor 3 (Increase in social work resources, 5 questions) was .83. The factor 4 (Increasing challenging business needs, 5 items) was .87, which was satisfactory for the reliability of internal consistency, and the Korean Version of Nurse's Job Crafting Scale was found to be an applicable tool. This study shows that the Korean Version of the Nurse's Job Crafting Scale is a valid and reliable instrument to assess nurses in Korea.

Nitrous oxide (N₂O) is one of the six major greenhouse gases and is known to produce a greenhouse ef ect by absorbing infrared radiation in the atmosphere. In particular, its global warming potential (GWP) is 310 times higher than that of CO₂, making N₂O a global concern. Accordingly, strong environmental regulations are being proposed. N₂O reduction technology can be classified into concentration recovery, catalytic decomposition, and pyrolysis according to physical methods. This study intends to provide information on temperature conditions and reaction time required to reduce nitrogen oxides with cost. The high-temperature ranges selected for pyrolysis conditions were calculated at intervals of 100 K from 1073 K to 1373 K. Under temperatures of 1073 K and 1173 K, the N₂O reduction rate and nitrogen monoxide concentration were observed to be proportional to the residence time, and for 1273 K, the N₂O reduction rate decreased due to generation of the reverse reaction as the residence time increased. Particularly for 1373 K, the positive and reverse reactions for all residence times reached chemical equilibrium, resulting in a rather reduced reaction progression to N₂O reduction.

This essay aims to seek an alternative model of catechesis, as this form of education faces various challenges from the Korean Church especially during COVID-19 pandemic. For a long time, catechesis in the Korean Church narrowly focused on the act of producing Christians who would be loyal to the local church, rather than focusing on nurturing members loyal to Christ, an issue that has been problematized in recent publications on catechesis. Thus, the loss of social trust in the Korean Church and the decline of its public image exemplify how this type of catechesis as disciple-making for local church's benefit, mostly nurtures a vertical dimension of faith. The current teaching and learning method mostly employs a unilateral transfer of doctrine from the teacher to the learner and emphasizes the memorization of doctrine. This type of instruction renders the catechesis as the most lackluster and outdated form of Christian education. This essay aims to reconceptualize the traditional model of catechesis. This essay first critically evaluates current situations of catechesis and presents several alternative meanings on the concept of doctrine. Then it explores the theories of catechesis through different models posed by Christian educators such as John Westerhoff III and Richard Osmer. The final section is devoted to presenting an alternative form of catechesis that focuses on seeking holistic faith.

Objectives: Although the number of clinics offering temporomandibular joint (TMJ) physical therapy has been increasing to help with its treatment, the scope of dental physiotherapy reflected in the dental hygienist curriculum is very limited. This study aims to survey the status of dental physiotherapy work and the need for educating dental hygienists. Methods: An online community platform was used to survey 140 dental hygienists working in clinical dental hospitals. The survey included questions about general characteristics, the experience of dental physiotherapy work, the importance of physiotherapy work performance, and the need for physical therapy education for dental hygienists. Results: Half of the study participants had prior experience working in dental physiotherapy. Out of 140 participants, 88.6% agreed with the opinion that 'physical therapy work is important or that it will become important'. Furthermore, 84.3% agreed that 'physical therapy education is necessary for dental hygienists'. Even dental hygienists without physical therapy experience (50.7%) believed that related education would be necessary because of the importance of physical therapy work in dentistry. Conclusions: This study suggests the need for education in dental physiotherapy to help dental hygienists effectively perform clinical tasks.

This study analyzed students' polar literacy in an effort to promote polar education based on its high educational value. The polar literacy test items developed for this study consisted of questions about knowledge, skills, attitudes, and beliefs about the polar region, as well as background variables of students. The final test items, which were revised and supplemented several times through the preliminary test, were applied to 323 eighth graders in South Korea. We analyzed the response characteristics of the polar literacy questions for all students. Students were grouped into those with a global citizenship perspective and those with a pragmatic perspective, according to the viewpoint of polar issues and their polar literacy. Analysis showed that the students had a high understanding of climate change and living things in the polar regions, but had a very low understanding of ice, which is a key component of the polar regions. Moreover, they were unable to approach the Earth system thinking when dealing with polar issues. In addition, the global citizenship group had a higher intellectual understanding and deeper sympathy of the polar problem than the pragmatic group. This study is meaningful in that the survey results present a specific direction for future polar education.

This paper presents a novel convolutional neural network (CNN)-based approach for predicting bolt clamping force in the early bolt loosening state of bolted structures. The approach entails tightening eight bolts with different clamping forces and generating frequency responses, which are then used to create a similarity map. This map quantifies the magnitude and shape similarity between the frequency responses and the initial model in a fully fastened state. Krylov subspace-based model order reduction is employed to efficiently handle the large amount of frequency response data. The CNN model incorporates a regression output layer to predict the clamping forces of the bolts. Its performance is evaluated by training the network by using various amounts of training data and convolutional layers. The input data for the model are derived from the magnitude and shape similarity map obtained from the frequency responses. The results demonstrate the diagnostic potential and effectiveness of the proposed approach in detecting early bolt loosening. Accurate bolt clamping force predictions in the early loosening state can thus be achieved by utilizing the frequency response data and CNN model. The findings afford valuable insights into the application of CNNs for assessing the integrity of bolted structures.

Purpose: The purpose of this study is to objectify the analysis results using the disaster safety awareness survey for high school students, which has been systematically and continuously educated since the Ferry Sewol disaster, and to promote educational effects by identifying the educational status. Method: The 12 questions of the disaster safety awareness survey were answered using the direct entry method on a Likert 5-point scale, and the SPSS 24 and varimax (orthogonal rotation) methods were used to establish and test research hypotheses. Result: As a result of the verification, it was found that the independent variables, knowledge competency and attitude competency, had a positive effect on the dependent variable, behavioral competency, and there was no multicollinearity, so it was verified that it was meaningful. Conclusion: As a result of the survey analysis, domestic disaster safety education showed a significant impact on the level of disaster safety awareness as an education that meets its goals. Various aspects of disasters show that the educational effect can be improved only when education is established as education by life cycle.

Bentonite is widely recognized and utilized as a buffer material in high-level radioactive waste repositories, mainly due to its favorable characteristics such as swelling capability and low permeability. Bentonite buffers play an important role in ensuring the safe disposal of radioactive waste by providing a low permeability barrier and effectively preventing the migration of radionuclides into the surrounding rock. However, the long-term performance of bentonite buffers still remains a subject of ongoing research, and one of the main concerns is the erosion of the buffer induced by swelling and groundwater flow. The erosion of the bentonite buffer can significantly impact repository safety by compromising the integrity of buffer and leading to the formation of colloids that may facilitate the transport of radionuclides through groundwater, consequently elevating the risk of radionuclide migration. Therefore, it is very important to numerically quantify the erosion of bentonite buffer to evaluate the long-term performance of bentonite buffer, which is crucial for the safety assessment of high-level radioactive waste disposal. In this technical note, Two-region model is introduced, a proposed model to simulate the erosion behavior of bentonite based on a dynamic bentonite diffusion model, and quantitative evaluation is conducted for the bentonite buffer erosion with this model.

Among the healthcare-related judgments handed down in 2002, there was a significant ruling on the timing of the duty of explanation, stating that, in order to ensure the exercise of the patient's right to self-determination, the patient must be given time to consider and decide on the risks and side effects of a medical procedure in specific circumstances. In addition, in a case where an insurance company claimed unjust enrichment against a medical institution on behalf of its insureds, the court provided a clear standard by distinguishing between active and passive requirements regarding the need to preserve the right of subrogation of creditors. In the area of medical administration, there was a ruling that clarified that a medical institution's business suspension under the National Health Insurance Act is directed against the medical institution, a ruling that broadly recognized causation in a case of compensation for side effects of corona vaccination, and a ruling on the scope of a medical practitioner's license, such as the use of ultrasound devices by an oriental medicine practitioner. In a case involving a patient's claim for eviction from a medical institution, the court reviewed a ruling on just cause for termination of a hospitalization contract in relation to Article 15(1) of the Medical law.
