According to previous studies, the key factor in determining the loan interest rate for shipping companies is the default risk premium. Therefore, this study analyzes the determinants of the risk premium of shipping loans using a multiple linear regression model. With the risk premium as the dependent variable, a total of 10 independent variables are selected, including three factors: loan characteristics, borrower's creditworthiness, and economic situation. Samples are 82 shipping loans supported by Bank A from 2014 to 2022. As a result, borrower's creditworthiness(current ratio, debt ratio, firm age) and economic situation(freight index) affect the risk premium in analysis for all samples. It is found that borrower's creditworthiness has some influence on the risk premium for container ships(current ratio, cash holding ratio, debt ratio, operating income to sales) and bulk carriers(debt ratio, firm age). Market situation affects the risk premium in gas carriers. However, in the model targeting tanker ships, unlike previous studies, all factors have no effect on the risk premium.

In order to minimize damage from disasters, rapid initial measures using disaster response manuals are needed. However, the existing disaster response manual is written in the form of a vast booklet, so there is a limit to accurately understanding the contents of the manual and using it for disaster response. Therefore, this study established an e-SOP system based on the disaster response manual, and suggested countermeasures using the e-SOP in the event of a disaster. Based on the guidelines for preparing the on-site action manual, the main functions of the e-SOP consisted of situation propagation, situation reporting, and situation management. In order to increase the on-site responsiveness and usability of the system, the bottom-up reporting system was strengthened so that the person in charge could report the response situation of the site to the situation room using the situation reporting function. In addition, the situation room was able to identify and manage the progress of disaster response work and support decision-making through situation reports delivered from the field.

The purpose of this study is to compare the child care time, as well as the perceptions of and satisfaction with the time use, of fathers and mothers in dual-income families with preschool children. 444 time use data were gathered from the Statistics Korea Life Time Surveys in 2019. The results of this study are as follows. First, the total child care time of the two parents per family on a working day was 72.1 min on average, and more time was spent on primary care than on developmental care. Second, the father's child care time on a working day was 40.8 min on average, and the mother's time, almost three times more-110.3 min, which show a significant difference. By type of care, the mother's care time was about three times more than that of father for primary care, and about two times more for developmental care. Third, the mother's primary care time differed by household income level, and the primary care time of both fathers and mothers differed according to the number of their working hours weekly. Fourth, both fathers and mothers felt somewhat tired and had a time deficit, but mothers were less satisfied than fathers with the division of household tasks between them. To encourage fathers' voluntary participation in child care, they must be informed of their joint responsibility with their spouse as parents must be emphasized under the term "co-parenting." It is necessary to expand systems that support parental care and promote a family-friendly culture in workplaces to guarantee the rights of parents.

This study aims to address the sustainability of South Korea's conscription system, which is being questioned due to issues like low birth rates and societal changes, and to explore the necessity and implementation strategies for transitioning to an all-volunteer force (AVF). South Korea has long maintained national security through conscription, but it now faces challenges such as a decrease in military resources and the advancement of high-tech military technologies. To address these challenges, the study analyzes domestic and international cases of AVF and assesses the current state and issues of South Korea's military service system. The findings indicate that an AVF can enhance military professionalism and efficiency, respect individual choice, and contribute to reducing gender imbalance and promoting social equity. A phased roadmap for the implementation of the AVF is proposed, along with the need for legal and institutional frameworks and measures to foster public consensus. The study also discusses the potential positive economic impacts and long-term cost savings of the AVF. This research aims to provide concrete strategies and policy recommendations for adopting a Korean-style AVF, thereby proactively responding to changes in the future security environment and establishing a sustainable national defense posture.

Purpose: This study is a comparative study conducted to examine the differences in attitudes toward COVID-19 prevention, self-leadership, and infection prevention behaviors among nursing students based on their experience in community volunteer related to infection disease prevention. Method: A total of 286 nursing students (146 in the experimental group and 140 in the control group) from 14 regions across the country were conveniently sampled from November 1 to 30, 2021, and the average difference in each variable according to participation in volunteer activities was analyzed using a t-test. Results: The comparison of differences based on participation in volunteer activities showed that the group with volunteer experience had a statistically significantly higher score in all variables: attitudes toward COVID-19 prevention (42.25±5.35 points) compared to those without experience (40.02±6.30 points)(p=.001), self-leadership (72.04±13.18 points) compared to those without experience (66.58±10.85 points)(p<.000), and infectious disease prevention behavior (44.31±7.62 points) compared to those without experience (39.38±7.20 points)(p<.000). Conclusion: This study provides practical and educational implications by suggesting a direction for educating nursing students who will need to provide actual care in future infectious disease outbreaks. These results suggest that nursing students could carry out volunteer service related infection diseases prevention through customized education and promotion programs for different target groups, which could be supported by school budgets, club activities, or incorporated into regular courses. Furthermore, it can be utilized as foundational data for the development of future nursing education programs

With the development of modern society, the number of livestock is increasing, and the corresponding odor is recognized as a serious social problem. In particular, the consumption of poultry meat, such as chicken, duck, and turkey, is expected to rise steeply, making odor problems near poultry farms. To address the problem, it is important to understand the influence of odor components on the complex odor. In this study, the odor data obtained from poultry farms were used to predict the complex odor using machine learning models and analyze the influence of the components. Furthermore, we analyze the differences in the amount of the odor components at the site boundary, compost site, inside the farm, and outside the farm using analysis of variance. The analysis showed that ammonia, trimethylamine, dimethyldisulfide, and acetaldehyde have a high effect on the complex odor. In particular, ammonia, trimethylamine, and acetaldehyde have different amount of the occurence by the location.

In the Fourth Industrial Revolution era, global powers are enhancing R&D support to leverage innovations like AI, IoT, and big data for productivity gains and structural economic and social reforms. Yet, the declining R&D budget growth rate and the forecasted sharp cut in South Korea's R&D budget in 2024 highlight the critical need for national R&D performance management system discussions. Diverging from previous studies focused on quantitative analysis of performance determinants, this research utilizes fuzzy set qualitative comparative analysis(fsQCA) to explore the interplay of factors affecting research institutions' outcomes comprehensively. Analyzing data from 2018 to 2022, it examines three outcome types of research institutions, identifying factor combinations crucial for success. By pinpointing these factors' configurations, the study offers institution-specific performance enhancement guidelines and insights for national R&D policy management and performance evaluation efficiency.

The purpose of this study is to explore tasks based on the current status of autonomous schools currently in operation. The research method used the method of literature research. In addition, the research contents were divided into the significance and development of autonomous schools, the types of autonomous schools, the current status of autonomous schools, and the areas of tasks. In the significance and development of autonomous schools, as alienation from standardized and standardized education occurred, autonomous schools with special cases for school and curriculum operation were systematically guaranteed for the improvement and development of the education system, including the school education system. Next, the types of autonomous schools were divided into general autonomous schools and Jeju autonomous schools. The general type is based on the Elementary and Secondary Education Act, and the Jeju type is operated under the Jeju Special Act, and the contents are also different, so their characteristic aspects were examined. Finally, the current status and tasks of autonomous schools were discussed. The characteristic aspects of the general and Jeju types, which differ in legal basis and content, were examined, and tasks were presented accordingly. The tasks were presented as the large number of autonomous schools, the concentration by region and type, the use of special cases mainly on institutional aspects such as principal qualifications and school management committees, and the smoothness of manpower support in Jeju. As a result of these discussions, it was requested to operate a substantial autonomous school, not a formal autonomous school operation.

This study aims to identify factors affecting the young and middle-aged people's stigma against older adults. By identifying the factors, solutions to lower stigma against older adults can be found. For this study, data from '2017 Age Integration Survey' sponsored by National Research Foundation of Korea and collected on March 2017 were used. Subjects of this study are 854 survey participants residing in 15 districts of South Korea. They are 480 young people aged from 18 to 44 and 374 middle-aged people aged from 45 to 64. T-test, Chow test and Multiple Regression Analysis by SPSS were conducted for the data. These are the results. Both the young and middle-aged people have a similarly high level of stigma against older adults. However, there are significant differences in the variables affecting the level of stigma against older adults between the two age groups. Two common variables affecting stigma against older adults in young and middle-aged people are the recognition of how older adults are depicted in media and age flexibility. The better they recognize discrimination against older adults in media and what an age flexible society is like, the stronger stigma against older adults they tend to have. On the other hand, sex, average monthly income and the opinion on how people treat older adults in their community are significant variables only for the young people. And living district is a significant variable only for the middle-aged people. The significance of this study is that it conceptualized 'stigma' as a cause for discrimination against older adults and focused on the stigmatizing subject, who are the young and middle-aged people, not the stigmatized subject, who are older adults in order to find solutions for lowering stigma against older adults.
