Background: As self-employed workers are vulnerable to health problems, this study aimed to analyze mental health problems and sleep disturbances among self-employed workers compared with paid workers in Korea. Methods: A total of 34,750 workers (23,938 paid workers and 10,812 self-employed workers) were analyzed from the fifth Korean Working Condition Survey, which included 50,205 households collected by stratified sampling in 2017. To compare mental health problems and sleep disturbance among self-employed workers and paid workers, multivariate logistic regression analyses were performed. Results: The odds ratio in self-employed workers compared with paid workers was 1.25 (95% confidence interval [CI]: 1.09-1.42) for anxiety, 1.11 (95% CI: 1.04-1.17) for overall fatigue, 1.11 (95% CI: 1.04-1.20) for difficulty falling asleep, 1.10 (95% CI: 1.02-1.18) for difficulty maintaining sleep and 1.24 (95% CI: 1.16-1.32) for extreme fatigue after waking up. Conclusions: Self-employed workers in Korea have a higher risk of self-reported mental health problems and sleep disturbances than paid workers. Further studies with a longitudinal design and structured evaluation are required to investigate the causal relationship between health problems and self-employment.

Background: Occupational pesticide exposure is a potential risk for respiratory health effects. Most clinical studies on pesticide exposure were related to acute exposure, and only a few studies on chronic exposure have been conducted. This study investigated the chronic respiratory health status and the chronic effects of occupational pesticide exposures of farmers in Gyeonggi-do. Methods: Surveys and pulmonary function tests were conducted on 1,697 farmers in 16 regions of Gyeonggi-do. The structured questionnaire included demographic characteristics, medical history, recent respiratory symptoms and diseases, and work-related conditions, and was conducted through one-on-one interviews. The prevalence of respiratory diseases was compared by the odds ratios (ORs) at 95% confidence intervals (CIs) estimated by logistic regression analysis. Additional multivariate logistic regression analysis was also conducted. Results: Pesticide work groups showed significant association with an obstructive pattern in the lung function test (unadjusted OR, 2.38; 95% CI, 1.17-5.52). Selected work-related variables of pesticide exposure were 'start age,' 'cumulative duration,' 'mixing pesticides,' and 'protection(goggle).' The obstructive pattern of lung function test showed significant associations with mixing pesticides (OR, 2.30; 95% CI,1.07-5.46), and protection (goggle) use (OR, 0.34; 95% CI, 0.12-0.79). Conclusions: Mixing two or more pesticides showed a significant association. Wearing goggles can be seen as an indicator of awareness of the protective equipment and proper wearing of protective equipment, and loss of pulmonary function can be prevented when appropriate protection is worn.

Background: Hotel housekeepers are one of the most important occupational group within tourism hotel sector; various health problems related to their job have been described, above all musculoskeletal disorders. The objective of this study is to understand the experiences and perceptions of hotel housekeepers and key informants from the Balearic Islands (Spain) regarding occupational health conditions and the strategies employed to mitigate them. Methods: A qualitative study was carried out. Six focus groups with hotel housekeepers and 10 semi-structured interviews with key informants were conducted. Next, we carried out a content analysis. Results: Hotel housekeepers reported musculoskeletal disorders, anxiety and stress as main occupational health problems; health professionals underscored the physical problems. Hotel housekeepers perceived that their work (physically demanding and with repetitive movements) caused their health conditions. To solve health issues, they used medication (anti-inflammatory agents, painkillers, sedatives and anxiolytics), which allowed them to continue working; health public services, generally rated as satisfactory; individual protective equipment; ergonomics (with difficulties due to high work pace and hotel facilities) and physical activity. Two contrasting attitudes were identified regarding sick leave: HHs who refused to accept a doctor-prescribed sick leave (due to fear of being fired, sense of responsibility, ...), and those who accepted it (because they could not continue working, they prioritised health before work). Conclusions: Our results might contribute to plan improvement strategies and programs to address health problems among hotel housekeepers. These programs should include interventions, such as coping strategies for the work-related risk factors (i.e., stress) and strategies to reduce medicine consumption. Additionally, hotel facilities should adopt policies focused on making workplaces more ergonomic (i.e., furniture) and to diminish the work pace.

Korea has preserved a highly sophisticated silk fabric culture throughout its history. Among these fabrics, Ra (羅) was considered to be a premium gauze fabric that required advanced skill and dedication to utilize. Ra is a complex gauze fabric in which four warp threads are twisted together and intersect with the weft to form intricate holes. This unique structure gives Ra its distinctive transparency and elasticity among silk textiles. It was widely used for veils, garments, and various items from the Three Kingdoms period to the Joseon Dynasty. However, its complex weaving process limited production efficiency, leading to its decline. Today, Ra has become obsolete. This study focuses on the elastic characteristics of Ra, where intersecting warp threads create net-like structured holes. This stucturre was emulated by developing a silk knit using a Raschel knitting machine. The developed product consists of three types: one replicating the alternating complex structure present in the traditional patterns of Munra (紋羅), another reproducing the distinctive hexagonal holes of the 4-end complex gauze, and the last expressing the hexagonal holes with the weft passing through them. Inspired by Ra's traditional uses in clothing and everyday items, various products were designed and produced. These include a women's coat with Akjureum, a 17th-century Joseon-style women's Jeogori, a modern market-style Jeogori, and a envelope inspired by a Goryeo Dynasty pouch artifact. These items confirm the potential and applicability of the developed silk knit as a material for modern Hanbok products. This study underscores the significance of developing new textiles that incorporate traditional materials, highlighting how tradition can be preserved in diverse ways.

The purpose of this study is to understand the meaning and context of adolescents' experiences of repetitive self-injury and to suggest that self-injurious behavior has characteristics of addictive disorder. In-depth interviews were conducted from December 26, 2022 to January 1, 2023 by using a semi-structured questionnaire for six adolescents who are attending outpatient psychiatirc clinic showing repetitive behavior of self-injury. The data were analyzed using Colaizzi's phenomeno-logical method focused on deriving the common attributes of all participants. We classified derived common attributes in the aspect of the diagnostic criteria of DSM-5 addictive disorder. 21 sub-themes and 6 categories were derived by gathering common meanings from 268 semantic units. The six categories of this study were raging pain, a wound that cannot not be revealed, extreme pores being pierced, continuous longing for self-harm, process of moving forward with pain. In the future, there is a need to develop various systematic intervention programs, including effective coping methods to help clinical adolescents' recover from self-injury, and further evaluation and research on them.

Research on the integration of Knowledge Graphs (KGs) and Language Models (LMs) has been consistently explored over the years. However, studies focusing on the automatic generation of text using the structured knowledge from KGs have not been as widely developed. In this study, we propose a methodology for automatically generating specific domain-related research items (Related Work) at a level comparable to existing papers. This methodology involves: 1) selecting optimal prompts, 2) extracting triples through a four-step refinement process, 3) constructing a knowledge graph, and 4) automatically generating related research. The proposed approach utilizes GPT-4, one of the large language models (LLMs), and is desigend to automatically generate related research by applying the four-step refinement process. The model demonstrated performance metrics of 17.3, 14.1, and 4.2 in Triple extraction across #Supp, #Cont, and Fluency, respectively. According to the GPT-4 automatic evaluation criteria, the model's performamce improved from 88.5 points vefore refinement to 96.5 points agter refinement out of 100, indicating a significant capability to automatically generate related research at a level similar to that of existing papers.

The purpose of this study was to confirm the relationship between self-esteem, family strength, and awareness of support for the elderly among college students, and to identify factors that affect awareness of support for the elderly. The participants of the study were 131 college students, and data was collected using a structured questionnaire from March 26 to April 11, 2024. Data analysis was performed using Independent t-test, One way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. The results of the study showed a positive correlation between self-esteem and family strength (r=.49, p<.001), and between family health and awareness of support for the elderly (r=.30, p<.001). Factors that influence the participant's awareness of support for the elderly are age (β=-.18, p=.029), sibling status (β=.18, p=.027), and family strength (β=.26, p=.002). Based on the results of this study, it is necessary to have college students actively participate in programs related to the elderly so that they can have a positive attitude toward the elderly and establish correct values through continuous interaction with the elderly.

Background: The design, implementation, and evaluation are three important stages of occupational safety and health (OSH) interventions. Historically, there has been a tendency to prioritize implementation, often neglecting detailed design and rigorous outcome evaluation. Currently, much has changed, and contemporary approaches recognize the interdependence of these stages, considering them integral to the success of any intervention. This work presents a comprehensive procedure for implementing interventions, not only to ensure short-term effectiveness but also their long-term sustainability through continuous monitoring. The focus is on a national OSH project introducing a near-miss management system (NMS) in Italy. Methods: Initial meetings were convened among project partners, complemented by interviews with diverse stakeholders, to plan implementation steps and test the NMS. Tailored questionnaires were designed for diverse stakeholder groups - initial promoters, company managers and employers, and employees - facilitating targeted implementation, and three case studies were started in Italian regions to assess the structured implementation, involving intervention promoters and collaborating companies. Results: The primary outcome is the development of practical tools, specifically three questionnaires, which are considered valuable for establishing an effective human-centered implementation strategy, meticulously designed to facilitate ongoing monitoring of processes and continual enhancement of instruments intended for NMS integration within companies. Conclusions: This work lays the foundation for successful NMS implementation in Italy and, although the outlined procedure had specific objectives, it also provides valuable insights applicable in enhancing the effectiveness and sustainability of interventions across diverse contexts. It underscores the importance of comprehensive planning, stakeholder engagement, and continuous evaluation in achieving lasting OSH interventions.
