  • Greenhouse gas emissions and environmental pollution persist globally, leading to an increase in extreme weather events, such as floods and droughts. Previous studies have investigated various factors for energy consumption, such as household, residential, economic, and social characteristics. However, the body of research examining energy-saving behavior and perceptions remains limited and underexplored. In particular, significant differences in energy conservation perceptions can be observed among individual household members, even within the same household. To this end, this study explores how household energy consumption is associated with various factors, including household characteristics, housing characteristics, energy-saving behaviors, and seasonal factors. We utilize survey data from the Household Energy Panel, spanning a 24-month period from January 2018 to December 2019, comprising a sample of 5,897 households across 17 cities and provinces nationwide. The findings of this study are expected to offer an empirical evidence for household energy-saving policies.

  • This study investigates the perceptions, Stages of Concern (SoC), and Levels of Use (LoU) regarding process-based assessment among Home Economics (HE) teachers to determine the necessary support for its implementation in schools. Data were gathered from a survey administered to HE teachers. The results are as follows. First, HE teachers viewed process-based assessment favorably, valuing its multifaceted evaluation approach over result-based assessment. The feedback from process-based assessments was seen as an opportunity for reflection for both educators and students. While some teachers expressed uncertainty about the optimal timing of implementation, they generally demonstrated a sound understanding of the feedback concept within the assessment process. HE teachers were predominantly concerned with their own professional expertise and the learning outcomes of their students. The majority of HE teachers have utilized process-based assessments for at least one semester. None deemed it irrelevant to their practice or showed disinterest in its adoption. Those who had yet to implement it were either in the first(introduction) or the second(preparation) stages.

  • Uzbekistan, one of the top five cotton-producing countries in the world, primarily focuses its textile and fashion industry on raw cotton exports and the sewing industry. For Uzbekistan to achieve high added value, it is essential for the textile and fashion industry, which is currently at the CMT(cut, make, and trim) stage, to upgrade to OEM (original equipment manufacturing), ODM (original design manufacturing), and OBM (original brand manufacturing). South Korea recognizes Uzbekistan as a potential manufacturing base and trading partner and has invested Official Development Assistance (ODA) funds for the development of Uzbekistan's textiles and apparel sector. This study aims to evaluate Uzbekistan's fashion higher education in the context of global competitiveness and measure the need and prospects for education ODA from the Korean government in this field. Comprehensive investigations, including surveys of academics, industry experts, and government officials, in-depth interviews, and focus group interviews, were conducted to understand Uzbekistan's current fashion education environment. According to the research results, despite the textile and fashion sectors playing a pivotal role in the Uzbek economy, there is room for improvement in the curricula and teaching and learning methods of the fashion higher education programs. This study holds significance as foundational data for establishing education ODA strategies.

  • Unlike conventional construction production methods, OSC (Off-Site Construction) have many restrictions depending on the production environment and technology, so it is important to develop a design plan considering these restrictions and select the optimal design alternative considering the overall efficiency of the building production process. Accordingly, the construction industry is paying attention to DfMA (Design for Manufacturing & Assembly) to derive the optimal design plan for the OSC project. Leading OSC countries such as Singapore and the United Kingdom have recognized the need to apply DfMA and presented DfMA guidelines and application strategies suitable for the characteristics of the OSC industry, and several researchers are conducting research to integrate DfMA into the construction industry. However, in the case of Korea, the need for industrial application and industrial application of DfMA is recognized, but there are no methods and tools necessary to implement the concept of DfMA in the design of actual construction projects. Therefore, this study aims to present the basic direction of strategy for applying DfMA and developing tools for the development of the domestic OSC industry by analyzing the development and application of DfMA in overseas construction. The results of this study can be used as basic data for the development of DfMA tools suitable for the domestic OSC industry and the establishment of policies related to DfMA in the future.

  • ESG management has garnered significant recognition as a crucial concern across all global industries. Within the logistics sector, there is a growing awareness of the importance of ESG management. However, active engagement in ESG practices remains predominantly confined to large corporations, leaving small and medium-sized logistics companies lagging in their comprehension and implementation of ESG principles. Previous studies have consistently underscored the necessity of establishing ESG management guidelines. Furthermore, there has been a call to determine the relative weights assigned to various ESG implementation evaluation criteria, taking into account the distinctive attributes of each category of logistics company. This study endeavors to ascertain the weightings of ESG implementation evaluation items for different types of logistics companies by employing the Analytic Hierarchy Process (AHP) methodology. The framework of evaluation is based on the evaluation items outlined in prior research, particularly focusing on ESG management guidelines tailored for small and medium-sized logistics companies. The findings of the analysis reveal distinct prioritizations across different sectors within the logistics industry. For maritime logistics companies, the environment emerges as the foremost concern, followed by society, information disclosure, and governance. Conversely, land transportation companies prioritize society, followed by governance, environment, and information disclosure. In the warehousing sector, environment takes precedence, followed by society, information disclosure, and governance. Comprehensive logistics firms, on the other hand, prioritize the environment, followed by information disclosure, society, and governance. Such guidelines are pertinent for regulatory bodies and industry stakeholders seeking to assess ESG practices within these enterprises. Moreover, this research contributes to the body of knowledge available to domestic small and medium-sized logistics companies, aiding them in effectively navigating and implementing ESG management principles.

  • This study aimed to propose implications for mental health and cultural arts education, in which certain factors can contribute to acquiring and improving creativity in adolescents to cultivate the creative human resources required in future society. The study used panel data from the Korean Education Longitudinal Study provided by the Korea Educational Development Institute. First, we analyzed the correlation between mental health and creativity and then examined mediation and serial mediation effects of the frequency of participation in cultural activities and the experience of them between two factors. The results showed that mental health was significantly positively correlated with creativity. Additionally, the frequency of participation in cultural activities and their experience were confirmed to have partial mediating effects. In other words, sound mental health factors such as comfort, enjoyment and happiness, cultural education, and cultural activities were found to have positive effects on creativity in adolescents. To develop creativity in adolescents, this study suggests the following challenges: (1) enhancing positive mental health, (2) increasing participation in cultural and artistic activities, (3) actively developing education programs for the cultural arts on community and educational sites, and (4) using and promoting local cultural and artistic education programs. These are expected to make an important contribution to fostering talented adolescents with creativity and convergence.

  • North Korea's rapidly advancing drone development and operational capabilities have become a significant threat to South Korea's security. The drone incursions by North Korea in 2014, 2017, and 2022 demonstrate the technological advancement and provocative potential of North Korean drones. This study aims to closely analyze the military threats posed by North Korean drones and seek effective countermeasures. The research examines the development level of North Korean drone technology, its military applications, the characteristics and patterns of recent drone incursions, the adequacy and limitations of South Korea's current response systems, and future countermeasures. For this purpose, domestic and international research literature and media reports were reviewed, and specific North Korean drone incursion cases were analyzed. The results indicate that North Korea's small drones possess technological features such as small size, low altitude, low-speed flight, long-duration flight, and reconnaissance equipment. These drones pose threats that can be utilized for reconnaissance, surveillance, surprise attacks, and terrorism. Additionally, South Korea's current response systems reveal limitations such as inadequate detection and identification capabilities, low interception success rates, lack of an integrated response system, and insufficient specialized personnel and equipment. Therefore, this study suggests various technical, policy, and international cooperative countermeasures, including the development of drone detection and identification technologies, the utilization of diverse drone neutralization technologies, the establishment of legal and institutional foundations, the construction of a cooperative framework among relevant agencies, and the strengthening of international cooperation. The study particularly emphasizes the importance of raising awareness of the North Korean drone threat across South Korean society and unifying national efforts to respond to these threats.

  • We investigated the effect of spectral fitting wavelength interval variations and selection of absorption cross-section on the sulfur dioxide slant column density (SCD) retrievals from the scattered sunlight observation using a UV-Vis hyperspectral instrument. The sulfur dioxide slant column densities were retrieved from the combinations of multiple spectral fitting intervals and absorption cross-sections. The observation was carried out at the site 0.53 km away from a combustion site located in Gimhae from December 1, 2023, to January 23, 2024. The radiances were obtained on the line of measurement sight toward the stack of the combustion facility. The best spectral fitting intervals were found to be from 305.7 to 321.1 nm. In terms of the absorption cross-section dependency, the SO2 (293 K), O3 (223 K, 243 K) show the best spectral fitting for the observed radiances with both the smallest fitting residual and SCD error. The effects of the fitting interval and cross sections found in this study can be useful information for improving SO2 retrievals based on UV hyperspectral measurements.

  • We confirmed that the children affected by child abuse, which has recently become an issue in the counseling field, were the highest in the ages of 10-17, and the number of occurrences by parents was the highest. We tried to understand the hardships of parents with adolescent children while conducting counseling and parental education to understand the difficulties of parenting experiences that play an important role in growing children. Therefore, this study attempted to analyze the subjective perception types and characteristics of each type of parenting experience of parents with adolescent children using the Q methodology. After forming a Q population and extracting the 33-question statement of the Q sample, the P sample was classified into the Q sample of 35 parents with adolescent children, and the perception type analysis was conducted with the QUANL program. As a result of our study, it was found that Type 1 was the unconditional love and understanding type, which was recognized as a process of endless understanding of children, Type 2 was the "reflection and change type," which recognizes empathy with children, communication, and parental reflection and change, Type 3 was the "learning and psychological independence assistance type," which recognizes that children should be psychologically independent and grow, and Type 4 was the "regret and identity confusion type," which recognizes regret about raising children in childhood and identity confusion as parents. Our study is meaningful in that it classified the subjective perception structure of parenting experiences perceived by parents with adolescent children by type. It is expected that this subjectivity study on parenting experiences will be used as basic data for parental education and parental counseling to raise adolescent children.

  • The purpose of this study sought to examine the mediating effect of social support in the relationship between adolescents' family strength and school life adjustment. For this purpose, a survey was conducted from May 2023 to June 2023 on youth attending middle and high schools in Daegu and Gyeongbuk, and statistical analysis was performed on the data of 768 people without missing data using SPSS 21.0 program. The results of this study were as follows. First, the family strength perceived by adolescents was found to have a significant positive effect on school life adaptation. Second, the family strength perceived by adolescents was found to have a significant positive effect on social support. Third, social support was found to have a positive and significant effect on school life adaptation. Fourth, social support showed a partial mediating effect in the relationship between adolescents' perceived family strength and school life adjustment. These research results have implications in that they provide empirical evidence to help adolescents adapt well to school life based on healthy family relationships. In addition, we hope that this will serve as a practical basis for the use of parent education programs and family counseling programs that help adolescents adapt well to school life by eliciting social support through positive family functions at home.
