This study examines the wearing conditions of working clothes according to the working environment and working processes at machinery, automobile, shipbuilding industry sites. It also investigates the relationship between the wearing sense of working clothes and the overall comfort according to work processes. The hazardous working environment was high in the order of the shipbuilding industry, machinery, and automobiles. The findings on the harmful overall work environmental factors were the noise, heavy dust, and noxious fumes, respectively. In general, the satisfaction with the wearing performance of working clothes was low especially with regard to sweat absorbency, sweat permeability, body protection and covering, and the work motion suitability. In respect of the correlation between the overall comfort and the wearing sense of working clothes, the satisfaction was decreased in the order of movement comfort, sensual comfort, and physiological comfort.

The emission of noxious gases is a significant problem in pig production, as it can lead to poor production, welfare concerns, and environmental pollution. The noxious gases are the gasses emitted from the pig manure that contribute to air pollution. The increased concentration of various harmful gasses can pose health risks to both animals and humans. The major gases produced in the pig farm include methane, hydrogen sulfide, carbon dioxide, ammonia, sulfur dioxide and volatile fatty acids, which are mainly derived from the fermentation of undigested or poorly digested nutrients. Nowadays research has focused on more holistic approaches to obtain a healthy farm environment that helps animal production. The use of probiotics, prebiotics, dietary enzymes, and medicinal plants in animal diets has been explored as a means of reducing harmful gas emissions. This review paper focuses on the harmful gas emissions from pig farm, the mechanisms of gas production, and strategies for reducing these emissions. Additionally, various methods for reducing gas in pigs, including probiotic interventions; prebiotic interventions, dietary enzymes supplementation, and use of medicinal plants and organic acids are discussed. Overall, this paper provides a comprehensive review of the current state of knowledge on reducing noxious gas in pigs and offers valuable insights for pig producers, nutritionists, and researchers working in this area.

This study examined the work environment and wearing conditions of industrial protective clothing in shipbuilding workshops. It also investigated the relationship between the wearing sensation of industrial protective clothing and overall comfort, according to work process. In addition, the work posture according to work process was evaluated based on ergonomic factors. The wearing rate of industrial protective clothing was 73.3%, 66.7%, and 60.1% for workers engaged in welding, grinding, and painting, respectively. The harmful work environment factors, listed from most harmful to least harmful, were found to be high temperature pyrogens, noxious fumes, organic solvents, UV rays, and heavy dust. The aspect of wearing performance of industrial protective clothing that was most related to user dissatisfaction was poor sweat absorbency. In terms of the correlation between the overall comfort and the wearing sensation of industrial protective clothing, the satisfaction was low shown in orders of physiological comfort, sensual comfort, and movement comfort.

This study analyzes the work environment and the work clothes wearing conditions of shipyard painters. In addition to this, three types of experimental painting work clothes were evaluated by painters in terms of the material performance and wearing functions. The findings on the harmful painting work environmental factors were organic solvents, noise, heavy dust, high temperatures, and noxious fumes. The body parts damaged during painting operations were the skin, arms, whole body, and face. In general, the satisfaction with the wearing performance of work clothes for painting was low especially in regards to sweat absorbency, sweat permeability, body protection, covering, and the work motion suitability. The satisfaction with the wearing sense of painting working clothes (regardless of the type of material) was high in the order of movement comfort> sensual comfort> physiological comfort. The satisfaction in overall comfort according to the types of material was high in the order of nylon> SMS nonwoven fabric> SF nonwoven fabric.

This study examined the wearing conditions of working clothes of shipbuilding industry workers according to the working environmental factors and working process features. It was also investigated the relationship between the wearing sense of working clothes and the overall comfort according to work processes. In the working process of shipbuilding industry, the process of fitting, welding, grinding and painting were chosen by considering work environmental factors, disaster types, hazardous materials, work process features, working clothes and safety equipments of each work categorized. The workers of fitting process usually wore the standard working clothes, while more than 60% of the workers of welding, grinding and painting wore the specialized protective clothes. The hazardous work environmental factors such as noise, heavy dust, high temperature and noxious fumes affected to the workers of fitting, welding and grinding. However, the workers of painting were greatly damaged by organic solvent. The dissatisfaction with the wearing performance of working clothes was highly shown in the sweat absorbency, moisture permeability and body protection. In respect of the correlation between the overall comfort and the wearing sense of working clothes, the satisfaction was decreased in orders of movement comfort> sensual comfort> physiological comfort.

There are now the plating process that have many hazardous factor cause of the using numerous noxious chemical and bad working environments. The purpose of the study is to make a selection of suitable safety evaluation method that can analyze and righteously find with numerous hazardous factor of the plating process. And another purpose is to systematically adjust the risk of plating process by comprehension of the role of process, equipment, and source material. Therefore, these studies are carried out in the following three investigations of this report. The first research understands the injurious human health and environment by analyzing hazardous material based on the MSDS. To evaluate the safety of process and compartment, the second research is proposed the security secure counterproposal by using the FMEA and the HAZOP. The final research is devoted to systematically analyze the hazard by applying for reasonable guide word and doing the HAZOP for hazardous factor in specific process.

본 연구는 작업환경측정기관 분석실에서 많이 다루어지고 있는 유해화학물질에 대해 CHARM(Chemical Hazard Risk Management)을 이용한 위험성평가를 실시하고 위험성을 추정하였다. 이를 위하여 서울 및 경기지역의 위험성평가를 실시한 작업환경측정기관 6곳을 선정하였으며, 그 결과 화학물질 노출 위험성 물질은 29개 물질이 선택 되었다. 성상별로는 액체 16개, 고체 10개 물질이었고, 특별관리물질인(CMR) '발암성(Carcinogenic)' 1A - 11개, 1B - 1개, 2 - 8개, '생식세포변이 원성(Mutagenic)' 1A - 4개, 1B - 3개, 2 - 8개, '생식독성(Repro-toxic)' 1A는 해당물질이 없고, 1B - 1, 2 - 6개 물질이 포함되어 있었다. 위험성 추정 결과 '낮음'에 해당하는 물질은 30.4%, '보통' 66.1%, '높음' 3.6%로 평가 되었다. 또한 6개 기관의 각 물질별 위험성 추정 결과 2개 기관이 위험성 추정 결정 중 '높음'에 해당하는 물질을 포함하고 있었다. 본 연구를 통하여 화학물질 평가도구인 CHARM(Chemical Hazard Risk Management)을 이용한 위험성 평가를 시도하였다는데 그 의의가 있으며, 작업환경측정기관 분석실의 위험성과 관리 화학물질을 우선적으로 도출하여 안전성 평가 및 비상조치 계획 수립과 안전관리 매뉴얼 구축과 작업환경측정기관 분석실에 대한 사고 및 위험성 관리의 제도적 법적 관리의 기초 자료로 활용되기를 기대한다.
