This study on satisfaction with school food service (FS) programs was conducted with 485 middle school students and 515 high school students based on FS management type. There were four types of FS management: independent-conventional (IC), independent-commissary (ICM), contract-conventional (CC), and contract-delivery (CD). About seventy percent of the students expressed satisfaction with the food quantity of the school lunches. But one third of the students, who felt the quantity was insufficient, cited the small size of the rice serving. Many high school students cited the small size of the side dishes as well as the rice serving. It is suggested that the meal quantity should be determined in consideration of the students' physical development. The satisfaction with FS sanitation was lower than that with the meal quality, eating environment, and environment of dining room with respect to all four types of FS management, and was lowest in the CD. It is suggested that FS sanitation should be managed more thoroughly for the students' safety, and that the school FS Committee should carefully monitor the sanitary management of the contract FS companies by means of a well-designed and monitored management system. Most of middle and high school students expected good taste and a diversity of foods in their school lunches. Food taste should be improved, and various food materials and cooking methods should be used for balanced nutrition and greater student satisfaction, particularly in contract FS types (CC and CD).

Objectives: Standardized guidelines and reference points for a food security policy are necessary to guarantee that basic social safety nets work properly. Therefore, this study aimed to explore the basic concepts and detailed dimensions of food security, including the potential relevant indicators, and sought to establish standardized well-being baselines. Methods: A literature review and 14 expert roundtable discussions were carried out to analyze and extract the key concepts of food security. After determining these concepts and detailed dimensions of food security, a conceptual framework was modeled. Then, indicators for each local government that could be monitored and evaluated for each sub-area were suggested. Results: The concept of food security was defined as follows: Individuals should be provided with sufficient, safe, and quality food, which should be accessible to the community and available for use to achieve health and well-being. In addition, food security should be ensured sustainably in a changing environment. Four dimensions were suggested while conceptualizing food security. First, sufficient food, which means sufficient food supply in quantity, quality, and safety. Second, equitable food which includes creating environments in which high-quality and safe food can be purchased at an appropriate price and can be provided regardless of the socioeconomic gap. Third, healthy food which should be provided to promote people's health and happiness through the eco-friendly consumption of food. Fourth, sustainable food, which can be supplied in a sustainable manner and as part of an eco-friendly food system that considers the conservation of natural environments. Conclusions: The basic concepts and detailed areas of food security including the potential indicators proposed in this study, may be useful for developing and implementing various policies and programs to support food and nutrition security in the future.

Purpose: The small-scale environmental impact assessment conducted during the development project stage has focused on the preservation of the natural environment centered on non-urban areas, due to the nature of urbanization, health problems for citizens of high-density urban areas have a limitation in that they are relatively neglected. In the case of strategic environmental impact assessment and environmental impact assessment in urban areas, there is no basis for evaluation in urban areas because there are exceptions to be excluded from the target projects or there are no target project regulations for buildings. Therefore, in this research, we examined the problems with the target project such as the current environmental impact assessment, and tried to establish a system improvement plan that can solve them. Research design, data and methodology: After reviewing the current environmental impact assessment-related laws (including enforcement ordinances) and national land planning laws (including enforcement ordinances), exceptions such as environmental impact assessment in urban areas were identified and problems were identified. Based on this, an amendment to the Enforcement Decree was proposed to provide institutional support for the expansion of target projects such as environmental impact assessment in urban areas. Results and Conclusions: Through this research, it is expected that the projects subject to environmental impact assessment on development projects in urban areas directly related to the health of the people will be expanded, and the net function of the environmental impact assessment system will be maximized.

Groundwater is an essential drinking water source in Gyungbuk, South Korea. The primary source of nitrate in groundwater is from nitrogen fertilizers. Efficient management of a small drinking water plant requires a good understanding of its status such as the objective and the cognition of users. The objective of this study is to understand user situation and produce useful user-friendly policy based on user cognition. Most people who participated in this study, should take their groundwater from a good quality source. Even though they would like to have a good facility for getting safe water, they were reluctant to do it due to the cost used. It means that people who drink groundwater have no idea that health safety is affected by groundwater quality. The volume used depended upon personal activities such as agriculture and stockbreeding. We can easily find groundwater with nitrate that exceeds drinking water standards. Therefore, we have to carry out groundwater management with two categories ; 1) drinking water only and 2) others according to objectives in small drinking water systems.

본 연구는 고령사회를 앞두고 증가하고 있는 노인들의 자동차 운전에 대한 실태를 확인하고 향후 노인들의 안전한 자동차 운전에 대한 연구를 하는데 기초적인 자료로 사용하고자 하는 목적을 가지고 있다. P시에 소재하고 있는 노인복지관을 이용하고 있는 노인 128명을 대상으로 설문조사를 실시하였다. 설문조사를 통해서 노인들의 자가운전 현황을 파악하고, 자가운전을 하고 있다고 응답한 41명의 노인들을 대상으로 인지기능을 확인할 수 있는 한국판 몬트리올 인지기능평가(Montreal Cognitive Assessment Korean Version; MoCA-K)와 신경행동학적 인지상태 검사(neurobehavioral cognitive status examination; NCSE)를 실시하였다. 연구결과 대상 노인의 32%가 자동차운전을 하고 있었으며 매일 운전을 하는 경우(56.1%)가 가장 많고, 운전시간은 하루 1-2시간 정도(56.1%) 운전을 하는 경우가 가장 많았다. 차량사용목적으로는 여가활동(46.3%)에 많이 이용을 하였으며, 사고경험이 있는 노인은 31.7%였다. 인지기능검사 결과 개인에 따라서 특정항목에서 평균이하의 점수를 획득하는 경우가 있어 안전한 자동차 운전에 영향을 줄 수 있다는 것을 알 수 있었다. 그러므로 노인들의 안전한 자동차 운전을 위해서는 노인의 감소된 능력을 정확하게 측정할 수 있는 체계적인 평가시스템과 부족한 부분에 대해서 보완할 수 있는 운전재교육시스템의 의무화가 필요할 것으로 생각된다. 또한 향후 운전면허관리제도 및 갱신과 같은 노인의 운전을 위한 정부차원의 제도적 접근도 필요할 것이다.

Objectives: The purpose of this study is to provide basic data for the improvement of the working environment for health prevention and related countermeasures for shift workers. This study was conducted based on the Fifth Korean Working Conditions Survey (KWCS), which analyzed the health effects of shift work forces and compared them with preceding studies. Methods: By analyzing secondary rates using raw data from the 5th KWCS, 4,870 (9.7%) of the 50,184 total study subjects were divided into shift work and 45,314 (90.3%) non-shift work groups based on the response to shift status. Variables that could affect work health issues were identified and corrected. A cross-analysis was conducted to examine demographic characteristics (gender, age, and education level) of the workers and occupation characteristics (monthly net earnings, employment type, occupation, working period up to now, workplace scale, type of work system, and weekly working hours). In order to find the work health issue ratio between the shift and non-shift work groups, logistic regression was analyzed and the association with health problems according to shift type by gender was looked at through cross-analysis. Results: According to the surveys conducted from the 1st KWCS (2006) to the 5th KWCS (2017), the proportion of shift workers continued to increase. Also, muscular pains in the lower limbs (hips, legs, knees, feet, etc.) (OR=1.135, 95%CI 1.031-1.251), headaches, eyestrain (OR=1.580, 95% CI 1.428-1.748), anxiety (OR=1.715, 95% CI 1.402-2.099), difficulty falling asleep (OR=1.391), and other problems (OR=7.392) were reported. In addition, back pain, muscular pains in shoulders, neck and/or upper limbs, muscular pains in lower limbs (hips, legs, knees, feet, etc.), headaches, eyestrain, depression, anxiety, overall fatigue resulted in significant results for both male and female shift workers. Depression and anxiety were higher in female shift/circulation compared to males. Conclusions: The social nets for the health and safety of shift workers should be explored in a variety of ways, including management and supervision of shift sites, attempts to reorganize and improve the shift system, development of workers' health recovery programs, promotion, systematic treatment, and compensation systems.

This study quantitatively analyzes risks of industrial incidents to fisher on overseas tuna purse seiners and long liners. A Bayesian network is employed to analyze 478 cases of industrial incidents, comprising 401 cases from purse seiners and 77 cases from long liners, reported from 2019 to 2022. The highest risk of industrial incidents on purse seiners is attributed to diseases. Excluding diseases, risks are the highest during fishing: 5.31 times higher during catch handling, 2.05 times higher during maintenance, and 2.38 times higher during loading and unloading. The risk of industrial incidents caused by the hull is 9.50 times higher than those caused by fishing gear, 4.59 times higher than those caused by machinery, and 3.61 times higher than those caused by the caught fish. Among the types of industrial incidents, slips are the highest: 2.58 times higher than industrial incidents caused by being bump, 3.74 times higher than those caused by hit, and 3.94 times higher than those caused by imbalance and overexertion. For long liners, most industrial incidents are concentrated in diseases, with dental, musculoskeletal, skin, and respiratory diseases being the primary types of industrial incidents identified. This study aims to propose reduction measures for reducing the high-risk form of industrial incidents, specifically slips, and to present health management strategies for preventing diseases among fisher on overseas tuna fishing vessels. By addressing these aspects, this study seeks to contribute to the safety and sustainability of the overseas tuna fishing industry.
