Objective: The purpose of this study is to examine the difference between teachers' traumatic experience and teachers' organizational commitment while considering individual differences of the childcare teachers and to investigate the effect of childcare teachers' traumatic experience on organizational commitment. Methods: This study used an online survey and collected data from 235 respondents. Then the data were analyzed by using a one-way ANOVA test, Scheffe post-hoc analysis, and hierarchical regression analysis. Results: First, this study found that there was a statistically significant difference between the traumatic experience of childcare teachers and teachers' organizational commitment depending on the age and career stage of the childcare teachers. Second, the childcare experience of childcare teachers showed a positive correlation with experience, and the traumatic experience showed a negative correlation with the organizational commitment. Third, childcare teachers' traumatic experience had a negative effect on normative and continuous immersion, respectively. Conclusion/Implications: This study contributes to the literature by recognizing the events that occurred in the process of childcare and identified the cause of the decrease in childcare teachers' motivation to work. It also suggests the need for continuous research on traumatic events that childcare teachers' experience during work in order to protect the rights and interests of childcare teachers.

In general, similar or previous projects are mainly referred to in order to derive operational test and evaluation(OT&E) items after acquiring weapon system. The idea that a more systematic method is needed is spreading because some of OT&E items derived in this process are redundant or unnecessary. Therefore, in this topic, we plan to use WBS, a tool that classifies components into a hierarchical structure and manages development easily to achieve the weapon system development goal. In addition, the WBS tool is applied to the medium-sized standard vehicle project, which is currently being research and developed, to effectively derive OT&E items. As a result of deriving OT&E items by applying WBS to the vehicle development field and electric devices of the medium-sized standard vehicle project, the operability and relationship were judged early, and then contents of the evaluation items could be written substantially while working on environmental adaptability. In the future, it is judged that the efficiency will be increased if the method discussed in this paper is applied when deriving the OT&E items from the R&D development project.

Purpose: More than 60% of patients with advanced cancer experience pain, and uncontrolled pain reduces the quality of life. Nurses are the closest healthcare providers to the patient and are suitable for managing cancer pain using pharmacological and non-pharmacological interventions. This study aimed to identify factors affecting the performance of cancer pain management among nurses. Methods: This study was conducted among 155 participating nurses working at a tertiary hospital who had experience with cancer pain management. Data collection was performed between October 18, 2021 and October 25, 2021. Data analysis was conducted using descriptive statistics, the independent-sample t-test, one-way analysis of variance, and hierarchical regression analysis. Results: There were 110 subjects (71.0%) who had no experience of cancer pain management education. The results of regression analysis indicated that barriers included medical staff, patients, and the hospital system for cancer pain management (𝛽=0.28, P<0.001). The performance of cancer pain management was also affected by experience of cancer pain management training (𝛽=0.22, P=0.007), and cancer pain management knowledge (𝛽=0.21, P=0.006). The explanatory power of the variable was 16.6%. Conclusion: It is crucial to assess system-related obstacles, as well as patients and medical staff, in order to improve nurses' cancer pain management performance. A systematic approach incorporating multidisciplinary interventions from interprofessional teams is required for effective pain management. Furthermore, pain management education is required both for cancer ward nurses and nurses in other wards.

Purpose: This study aimed to investigate COVID-19 vaccination intentions in Korean parents for their children aged 5 to 11 years and the factors influencing them. Methods: A cross-sectional online survey of 363 parents of children aged 5 to 11 years was conducted in Korea in April 2022. Data were analyzed using independent t-test, χ² -test, Fisher's exact test, and hierarchical logistic regression analysis using SPSS/WIN 26.0 and MedCalc software version 20.113. Results: Of 363 Korean parents with children aged 5 to 11, 42.4% intended to vaccinate their children. Significant factors influencing vaccination intention were the second or third birth order of children (OR = 3.45, 95% CI = 1.45~8.21), vaccine hesitancy-confidence (OR = 2.00, 95% CI = 1.51~2.65), vaccine hesitancy-collective responsibility (OR = 1.57, 95% CI: 1.10~2.25), and COVID-19 anxiety-avoidance (OR = 1.55, 95% CI = 1.13~2.11). Conclusion: Findings suggest that COVID-19 vaccine campaigns based on reliable information and evidence from health authorities are needed to increase COVID-19 vaccination. Well-designed health communications for the target population may help to increase parental vaccine acceptance.

In the past, many state Departments of Transportation (DOTs) in the U.S. managed their highway assets on a "worst first" basis and planned their highway projects in a tactical rather than strategic fashion. Due to increasingly tight highway budgets and recognition of long term benefits of asset management systems, the Federal Highway Administration (FHWA) has strongly pushed and encouraged state DOTs to implement asset management for managing their highway assets and highway projects. Currently, many DOTs have actively implemented and are in the process of applying this asset management concept for their highway infrastructure. However, different DOTs are developing different asset management systems because of their different organizational structures, data management structures, relationship with the legislature, and investment priorities. This study first identifies asset management indicators which are essential to successfully implementing asset management systems for State highway assets. The research team conducted a survey of asset management experts and reviewed the practices and policies of leading DOTs in asset management. Based on these indicators, this study develops an Asset Management Assessment Model (AM²) for different asset management systems. This model can be used by different DOTs to evaluate their current asset management systems and identify their strong areas and also their weak areas to improve in order to fully benefit from the advanced concept of asset management.

If a system has a large boundary and complexity, forecast's accuracy will be very low when consider the system's substance as black box. Thus, it is necessary that analysis by structure model. To examine competition in Northeast Asia Ports, it has assumed that the form of structure model, For which the System Dynamics method is adapted in this paper. Northeast Asia Ports Model includes five ports - Pusan, Kobe, Yokohama, Kaoshiung, Keelung, - which are adjacent to each other by geographically and has a competition relation. The Northeast Asia Ports Model has several sub-systems which consists of each unit port models. And, each unit port model found by quantitive, qualititive factors and their feedback loops. All effects which components of one port have influence to components of the rest ports must be surveyed in order to construct Northeast Asia Ports Model, but it may be impossible currently. In this paper Northeast Asia Ports Model was simplified by HFP-Hierarchical Fuzzy Process Method-adapted to integration of level variables of unit port model. Container cargo volumes in Northeast Ports Model is distributed by results of HFP method. And distributed container cargo volumes effected to unit port model. Developed model can estimate change of container cargo volumes in competitive relation by alternation of simple parameter, and reflects dynamics characteristics which are included in model.

In the hierarchical framework, galaxies grow through mergers and accretion. Those mechanisms leave faint features, such as stellar streams, shells and smooth stellar halos in the outskirts of galaxies. In order to search for those features in the nearby galaxies, we are conducting a KMTNet Nearby Galaxy Survey using the Korea Microlensing Telescope Network. We present a deep and wide-field imaging of NGC 5236, a barred spiral galaxy. In one-dimensional surface brightness profiles, we reach 28, 29 mag/arcsec2 in the R- and B-band, respectively. We find that the outer disk of NGC 5236 can be well described with a single exponential profile up to 17 kpc (~3.8 Reff) indicating that the excess light due to the stellar halo is not clearly detected. B-R color gradually increases towards the outskirts of the galaxy. It may reveal that stellar properties in the outskirts are marginally distinctive from those in the central part.

As the demand for logistics services increases rapidly in modern society, the existing freight delivery system through road transportation is caused various problems such as traffic congestion and greenhouse gas emissions. To solve that, the development of an 'underground logistics tunnel-based cargo transportation system' is currently being considered in Korea. In order to build a new concept stable and safe logistics system, derive system design requirements and functional specifications, and reflect them at the development of target system. In this study, to make foundation for development of an "underground logistics tunnel-based cargo transportation system," define system components through analysis from a hierarchical perspective, and the functions of each component were analyzed and defined. We identified what interfaces the components have at each stage of the operating process. Lastly, we defined a detailed operation scenario based on the previously derived results, deriving target system functional requirements.

Purpose: The purpose of this study is to identify the effects of preceptor's empathy, grit, and nursing environment recognized by newly graduated nurses on the organizational socialization. Methods: In this study, from June 22 to August 21, 2022, a convenience sample was perfored for new nurses working at general hospital in four cities. Analysis of the collected data was using the SPSS/WIN 26.0 software. The data was analyzed using independent t-test, one-way ANOVA, Scheffé test, Pearson's correlation coefficients, and hierarchical regression analysis. Results: The factors influencing the organizational socialization of new nurses were the type of work (β=.26, p<.001) and nursing work environment (β=.21, p=.037), in the order of these variables. These factors wew found to account for 16% of variance in the organizational socialization of new nurses (F=4.59, p<.002). Conclusion: To increase the organizational socialization of new nurses, medical institutions must make efforts to improve the nursing work environment.

The emotion recognition system in commercial environments such as call-center undergoes severe system performance degradation and instability due to the speech characteristic differences between the system training database and the input speech of unspecified customers. In order to alleviate these problems, this paper extends traditional method of emotion recognition of neutral/anger into two-step hierarchical structure by using emotional characteristic changes and differences of male and female. The experimental results indicate that the proposed method provides very stable and successful emotional classification performance about 25% over the traditional method of emotion recognition.
