We surveyed 821 children (ages 12-15 y) in Daejeon city and Cunngcheong province, Korea for their use of vitamin mineral supplements (VMS), either over-the-counter drugs and/or health functional foods (HFF). We also considered the significant variables of VMS use, including demographic characteristics, health-related variables, eating habits and nutritional beliefs of VMS by subjects. The frequency of VMS use was 24.8% and, in comparison to counterparts, it was higher in subjects attending middle school (p<0.001), in those living in a large city (p<0.001), in those with a high monthly family income (p<0.05), and in those with high concerns about school performance by parents (p<0.01). Selfhealth concerns by subjects (p<0.05) and concerns about health of offspring by parents (p<0.01) were higher in users than in nonusers. Eating habits of subjects did not affect the use of VMS. Users had a more positive view concerning the potential health benefits of VMS than did nonusers (p<0.05). Most users took VMS when they were healthy (78.9%) and expected 'disease prevention and health maintenance' (44.6%). However, most users did not feel any special effects from VMS use (58.8%), and they got their information on VMS through family and relatives (53.9%). Users of VMS preferred vitamin C supplements (44.2%) and Ca-supplements (56.9%). Therefore, the results show that VMS use is widely spread among the subjects, and that use of VMS is influenced by multiple variables and subjective criteria. Therefore, practical guidelines on VMS use for children's health and growth should be given through nutritional education.

As advances in artificial intelligence (AI) increasingly approach areas once relegated to the realm of science fiction, there is growing public interest in using these technologies for practical everyday tasks in both the home and the workplace. This paper explores the applications of and implications for of using ChatGPT, a conversational AI model based on GPT-3.5 and GPT-4.0, in the field of occupational health and safety. After gaining over one million users within five days of its launch, ChatGPT has shown promise in addressing issues ranging from emergency response to chemical exposure to recommending personal protective equipment. However, despite its potential usefulness, the integration of AI into scientific work and professional settings raises several concerns. These concerns include the ethical dimensions of recognizing AI as a co-author in academic publications, the limitations and biases inherent in the data used to train these models, legal responsibilities in professional contexts, and potential shifts in employment following technological advances. This paper aims to provide a comprehensive overview of these issues and to contribute to the ongoing dialogue on the responsible use of AI in occupational health and safety.

Objectives: This study aimed to compare customers' perceptions of the need for a low-sodium diet and sodium-reduced operations in the industry foodservice by age. The relationships between health concerns and perceptions of the need for sodium-reduced operations and low-sodium diets in the industry foodservice were analyzed. Methods: A survey was conducted among 340 industry foodservice customers aged 20-50 years and residing in Seoul, Korea. This study investigated the respondents' health concerns, their perception of the need for sodium-reduced foodservice operations, their perception of a sodium-reduced diet, and the general details of the foodservices they used. A cross-tabulation analysis and ANOVA were performed to identify differences in measurement items by age, and a simple regression analysis was performed to examine relationships between measurement items. Results: For the customers' perception of the need for a sodium-reduced foodservice operation, the item "it is necessary to provide separate spices and sauces to reduce sodium intake" achieved the highest score (3.88 points out of a possible 5 points). For the perception of a sodium-reduced diet, the item "I think it is helpful for one's health" obtained the highest score (4.13 points). Respondents' health concerns had a positive effect on increasing the level of perception of the need for sodium-reduced foodservice operations and that of a sodium-reduced diet. Conclusions: Foodservice nutritionists could help enhance their customers' perceptions of the needs for sodium-reduced foodservice operations and sodium-reduced diets by frequently providing them with sodium-related health information.

The purpose of this study is to inquire into the degree of health promotion activity in university students, and to find out the relationship between self-efficiency and health promotion behavior, Thus, we can offer basic data for developing an educational method or program for health promotion. For this research, data was collected from university men and women through a questionnaire from February 18 to March 20, 1998. A measuring instrument was based on lating reviews of health promotion behavior in chronic disease protection, perceived self efficiency, demographic factors, biological factors, and circumstatial factors. The content validity of the instrument was authenticated by two professors of nursing, and reliability was confirmed by 'cronbach' (${\alpha}^{\prime}$ after mortifying content through a pre-test on 30 students. 475 persons were analyzed in terms of average, percentage, t-test, ANOVA, Pearson's Correlation Coefficient, and Multiple Stepwise Regression by 'SPSS-PC'. The analyzed data is as follows: 1. Higher self-efficiency, as a cognitive-perceptual factor, has a beneficial effect on health promotion behavior (r=.479, p=.000). The result of analyzing the differences among a low group, a middle group, a high group in terms of self-efficiency reveals that the relationship between self-efficiency and health promoting behavior is meaningful. 2. The degree of health promoting behavior is 3.26 out of 6. Other figuresrelating to health promoting behavior, are as follows. self-actualization area (4.62), interpersonal area (4.60), stress management area (4.01), nutrition area (3.68), responsibility of health area (3.11), liquid and cigaret area (2.85), and exercise area (2.33). 3. The degree of self-efficiency was 6.81 out of 10. Other figures relating to self-efficiency are as follows. interpersonal area (7.89), self-actualization area (7.84), liquid and cigarette area (7.72), exercise area (6.88), stress management area (6.84), responsibility of health area (6.35), and nutrition area (6.34). 4. The different lerels of health promoting behavior according to a subject's general factos are following: age (p=0.003), sex (p=0.000), health concern of parents (p= 0.000), taking health programs (p=0.007), case history of familes (p=0.048). Health promoting behavier is also positirely affeted by the following: higher age, social sciences focus, religion, living the relatives', and the higher health concerns of parents. 5. The difference of self-efficiency according to a subject's general factors is positirely affected by sex (p=.008), the health concerns of parents (p=.004), body indexes (p=.001), and the higher health concerns of parents. 6. As the result of analyzing major factors, the most powerful factor appears to be self-efficiency, 26.6% of health promoting behavior. Suggestions: 1. Results of this study point to self-efficiency as a major factor in the health promoting behavior of university students. It is crucial, therefore, to develop a health program to promote self-efficiency and to study how to promote prerention of certain diseases. 2. That health promoting behavior appears low in this study shows that health education should be taken into the university class, with a focus on the daily life of students as its goal.

Carbon nanotubes (CNTs) stand at the frontier of nanotechnology and are destined to stimulate the next industrial revolution. Rapid increase in their production and use in the technology industry have led to concerns over the effects of CNT on human health and the environment. The prominent use of CNTs in biomedical applications also increases the possibility of human exposure, while properties such as their high aspect ratio (fiber-like shape) and large surface area raise safety concerns for human health if exposure does occur. It is crucial to develop viable alternatives to in vivo tests in order to evaluate the toxicity of engineered CNTs and develop validated experimental models capable of identifying CNTs' toxic effects and predicting their level of toxicity in the human respiratory system. Human lung epithelial cells serve as a barrier at the interface between the surrounding air and lung tissues in response to exogenous particles such as air-pollutants, including CNTs. Monolayer culture of the key individual cell types has provided abundant fundamental information on the response of these cells to external perturbations. However, such systems are limited by the absence of cell-cell interactions and their dynamic nature, which are both present in vivo. In this review, we suggested two viable alternatives to in vivo tests to evaluate the health risk of human exposure to CNTs.

Urban air mobility (UAM) is emerging as an innovative transportation solution for cities. However, the potential noise impact on urban life must be carefully examined. Continuous exposure to UAM noise, with its unique frequency characteristics and temporal variability, may adversely affect citizens' health by causing sleep disorders, cardiovascular disease, and cognitive impairmenet, particularly in children. NASA has formed a UAM Noise Working Group to study this issue comprehensively. In Korea, the Seoul Metropolitan Government's UAM demonstration project is expected to accelerate related research and development. Scientific analysis, including noise measurement, prediction modeling, and health impact assessment, must be prioritized. Measures to minimize noise should be established based on this evidence, such as optimizing flight modes, developing noise reduction technologies, and establishing new noise management standards. Transparency and social consensus are crucial throughout this process. Expert review and open communication with civil society are necessary to address related concerns. Sharing demonstration project results and providing opportunities to experience UAM noise through digital twin simulations can help address public concerns and build social consensus. Proactively and scientifically tackling noise issues is essential for the sustainable development and successful integration of UAM into daily life.

Throughout the century, based on the precedent set by Flexner in the United States, almost every subsequent report on the reform of medical education has pointed out the need for more prevention-oriented teaching in the curriculum. This has been particularly so in countries like Korea where the basic public health services have been so important for the improvement of health of the people. And, in fact, preventive medicine and public health have contributed a great deal to the prevention of communicable diseases and prolongation of life expectancy. Recently, however, along with the educational reform that emphasizing the interdisciplinary teaching, integration of basic science and clinical education, and centralization of responsibility for the medical education curriculum, concerns are being voiced by preventive medicine educators. These concerns are primarily centered around the fear that the implementation of interdisciplinary, centrally administered courses would result in a weakening of content and teaching expertise as well as a loss of departmental power and control. This paper foresees that preventive medicine and public health will be more important in Korea in the future and proposes that preventive medicine educators will have to step forward and turn the challenges of curricula restructuring into opportunities to expand the role of preventive medicine in the curricula of their institutions.
