For safe mooring and towing between the ship and port, the equipment must be designed in accordance with the relevant international regulations. However, some small shipyards and engineering companies often do not fully comprehend the core contents. Therefore, the international regulations regarding towing and mooring equipment are reviewed and the bollard and chock are newly developed based on the Mooring Equipment Guideline 4 (MEG4) standards. A bollard is a mooring equipment used to fix a mooring rope to the hull. It has two columns and is mostly used in a figure eight pattern knots under the mooring condition. The chock, which is used to change the mooring rope direction coming into the ship from outside, is manufactured using a casting with curvature. The two mooring equipment are widely used in the stern, bow, and mid-side. Owing to the increase in the size of container vessels and LNG ships, the mooring rope load has increased and the safe working load of the mooring equipment must be revised. This study summarizes and examines the results of the allowable stress method obtained using finite element analysis modelling. To consider the mesh size effect, a reasonable criteria was suggested by referring the existing class guidance. Additionally, the safe working load was verified through nonlinear collapse analysis, and the elastic region against load increments was confirmed. Furthermore, the proposed evaluation method can be used to develop similar equipment in the near future.

Background: This study aimed to investigate whether there is a difference in organizational member attitudes by workplace environment and workplace types in dental hygienists working at dental health centers. Methods: A face-to-face survey or online survey was administered to dental hygienists working at dental health centers, and a total of 95 subjects were included. The survey includes 13 items to ask factors affecting employee's job satisfaction. Also, some questions were included to assess perception of organizational member attitude: five about organizational citizenship behavior, two about innovative behavior, and four about organizational commitment. Results: Dental hygienists working at dental clinics were more satisfied with their incomes and numbers of working days, while those from dental university hospitals and general hospitals were more satisfied with education support. In addition, hygienists working at dental hospitals were more satisfied with job autonomy, individual work capability, safe working environment, personal relation, potential for personal development, and positive labor-management relations, compared to those working at general and university hospitals (p<0.05). Among the items about perception of organizational member attitudes, the scores of items about organizational citizenship behaviors were higher, whereas the scores of items about innovative behaviors were relatively lower. Individuals working at dental hospitals than those working at general and university hospitals, chiefs and team and department leaders than team members, and those with increased satisfaction with current workplace had more positive perception of organizational member attitudes. Conclusion: For dental hygienists to have positive attitudes as organizational members, working environment should be improved, and executives of dental healthcare centers should pay attention to improving job satisfaction of organizational members. Moreover, since dental hygienists need to improve their perception of innovative behaviors and citizenship behaviors to strengthen specialty of dental hygienists in a changing dental healthcare, relevant training should be addressed in refresher courses or school programs.

Work-related musculoskeletal disorders constitute a major source of employee disability and lost wages. Cumulative Trauma Disorders(CTD) refers to a category of physical conditions which result from chronic musculoskeletal injury. Assessment of CTD risk in industry at early stage allows for early control, a safe environment, and a healthier workforce. In this study, the physical load of the shipping work in the cold storage warehouse were especially investigated. Employees were working with almost unnatural posture in a very restricted work space. The questionnaire and biomechanical analysis were used to evaluate the physical load. Results from analyses showed that they were sufficiently exposed to CTD due to repetition and unnatural posture. Based on the analysis, ways for improving working conditions are proposed. The analysis and proposals in this paper will serve as a basic tool for designing/redesigning working environment such as improvement of tools and equipments, design of times for work/rest cycle.

Purpose: The purpose of this study was to analyze the concept of nurses' safety within the context of the hospital environment. Methods: We used Rodgers' method of evolutionary concept analysis and reviewed the relevant literature and noted and categorized characteristics that appeared frequently. Results: Nurses' safety was defined as safe status and safe activity among nurses. Three key defining attributes were identified as: (a) the minimization of actual or perceived risk, (b) personal duties and rights, and (c) ensuring within a safe working environment. Antecedents of nurses' safety were categorized into three dimensions: (a) individual, including vigilance and knowledge gained through education and training; (b) institutional, including safety provision in the organizations; and (c) national, including legislation. The outcomes of nurses' safety included the following: (a) continued competence in nurses' work; (b) enhancement of the quality of patient care; and (c) reductions in nurses' turnover rates. Conclusion: Nurses' safety ensures that qualified nurses are able to continue to perform their duties and provide good patient care. The findings of this study could contribute to future research examining nurses' safety. In addition, appropriate tools must be developed to measure the concept.

The coastal composite fishery has the highest rate of around 30.0% in registered fishing vessels of Korea for the last three years. The risk analysis for the fisher's safety of coastal composite fishing vessels was conducted to serve as a basic data for improving the healthy and safe working environment of fisher using fisher's occupational accidents of the national federation of fisheries cooperatives (NFFC) from 2016 to 2018 (n = 1,105). As a result, the occupational accident occurrence rate of coastal composite fishery was 3.76% in all industries, 7.8 times the rate of that. In addition, death and missing rate was found to have a serious level management to 10.10‱. Among the accidents, 76.0% occurred at sea. The slipping, others and contact with machinery or fishing gear occurred more frequently in order in the frequency of accident occurrence pattern. In the risk assessment using frequency and severity, slipping, contact with machinery and others showed high risk during fishing. The results are expected to contribute to identification and assessment of safety hazard occurred in coastal composite fishing vessels.

As car-oriented road policies have been made forward so far, relatively pedestrians' walking conditions are so in poor environments that more than two thousand pedestrians die from car accidents every year. Pedestrians' walking right has been severely invaded like that. Pedestrians' walking right is a right that people are able to walk safely and comfortably in pleasant surroundings as long as they don't threaten the public safety, order maintenance, and welfare. The government has an obligation to provide safe, comfortable, and pleasant environments to pedestrians. Recently interests in pedestrians' safety are increasing, government-driven supports have been made to make safe, pleasant, and healthy walking surroundings. As poor walking condition improvement projects cost high, they should be progressed to accomplish maximal effects using finite finances efficiently, and post feasibility evaluations of the projects should be severely estimated. However site selecting indicators which satisfy with the goal for composing safe working surroundings have not been decided yet, though currently it has a legal basis to specify walking condition improvement sites by the Law for Pedestrians' safety and Comfort Increasement. Therefore this study focuses on suggesting improved ways for selecting sites where pedestrians' safe environment project by reviewing previous research. When project sites are selected, evaluation indicators related to awareness survey of residents and history should be excluded, and disaster safety assessments for walking safety facilities, latent human hazards and natural disasters like a strong wind are proposed besides evaluations on pedestrians' safety and walking environment for matching with the purpose of the project to make safe working surroundings.

Purpose: This study investigated the knowledge, attitudes, and perceptions of a safe environment, as well as self-reported and observed compliance with the use of personal protective equipment (PPE), among intensive care unit (ICU) nurses. Methods: This study was conducted in October 2021 with 55 nurses working in the medical and surgical ICUs of a general hospital in Seoul. A self-reported questionnaire and an observational tool for compliance with the use of PPE were used to collect data. Results: Except for masks, the observed compliance for all other PPE types was lower than the self-reported compliance. Male nurses showed significantly higher observed compliance than female nurses. Self-reported compliance with PPE use, including "when there is a possibility of contact with objects contaminated with blood or body fluids, mucous membranes, damaged skin, or contaminated skin" (r = .23, p = .015) and "when there is a possibility of contact with blood, body fluids, secretions, or exudates" (r = .27, p = .004) showed significant correlations with knowledge of PPE. In the results for self-reported compliance with PPE use, gown use had a significant correlation with knowledge (r = .24, p < .001) and perceptions of a safe environment (r = .15, p = .016) for PPE, and gloves showed significant correlations with attitudes (r = .14, p = .024) and perceptions of a safe environment (r = .18, p = .003). Conclusion: The observed compliance with PPE use tended to be lower than the self-reported compliance among ICU nurses. It is necessary to develop and apply an effective educational program that can enhance improve actual compliance with PPE use among intensive care unit nurses.

Existing safety education delivered to construction workers has limitations in concentration and immersion, so delivery power and interest are low. In order to improve the unstable behavior of construction workers and prevent safety accidents through education, a paradigm shift to hands-on education is necessary. Experiential safety education aims to contribute to the prevention of safety accidents and induce safe behavior by construction workers to recognize risks faster, select safe working methods suitable for the working environment, and improve emergency response and proactive response. Experiential education facilities have a follow-up learning effect in case of danger. The experience facility, which consists of the same working environment as the actual construction site, is designed to experience falls, equipment contraction, fire, and electric shock. In order to achieve the results of safety education that has invested a lot of time, construction workers must have motivation to participate, and "experiential safety education" through playful, deviant, and aesthetic experiences reduces serious accidents.

Objectives: The purpose of this study is to provide basic data for elucidating the clinical experiences of nursing assistants working at dental clinics and for establishing the bases necessary for building a safe working environment for the staff at dental clinics. Methods: From March 28 to August 20, 2022, the study conducted in-depth interviews with nursing assistants working with dental hygienists in dental clinics. The collected data were analyzed using the phenomenological method. Results: The study analyzed the meanings associated with the dental clinical assistance work experiences of nursing assistants in dental clinics. A total of 98 semantic words and 9 sub-categories were extracted, which were ultimately categorized into 4 central meanings: 'imperfect reality', 'work without boundaries', 'putting oneself in someone else's shoes', and 'symbiosis'. Conclusions: The nursing assistants were exposed to an environment where they needed to perform delegated treatment procedures even when they lacked dental work competency. They recognized their gaps in learning and the necessity for designated roles as clinical assistants. Thus, it is necessary to review the allocation and expansion of the work roles of dental practitioners based on the practical and rational realities in dental practice.
