Even though continuous management and supervision of reinforcement of policies to safeguard accidents at workplace and work sites were implemented. Accident prevention activities such as inspection and diagnosis are urgently required to induce a preliminary investigation to identify the risk factors for each type of work, before the work task to eliminate risks at the worksites. Since safety inspections at work sites were generally conducted through visual inspections, the results of safety inspections may vary depending on the findings and proficiency of the safety officers. The results of those inspections may have loopholes to prevent potential accidents at work. Therefore, the purpose of this study was to develop a risk identification checklist that can effectively perform safety inspections to prevent accidents at work sites. This study initially analyzed the previously developed accident checklist to identify current complications and issues in safety checklists. Based on the findings of major industrial accidents over the past three years, the relationship between accident, workplace, and work type were analyzed refereeing the safety inspection standards. A risk recognition-checklist was developed to provide basic data on identifying risk factors, and inspection guidance at work sites. To prepare for potential accidents by identifying and taking countermeasures to mitigate the high risk and serious accidents at sites by the guidelines of the checklist. The developed inspection checklist has been practically used by experts at work sites to perform safety inspections, and it has been verified its suitability, and feasibility, to prevent or mitigate workplace accidents, including securing the safety and health of field workers. The role of the developed safety checklist has been considered effective at worksites.

The main point of this study is to find ways to prevent accidents at complex linear sections in advance by improving geometric structure elements that can be considered from the designing stage. Complex linear roads are consisted of sections where straight sections connect with curved sections or sections where curved sections connect with curved sections with relatively high possibility of accidents and accidents can be reduced through improving designing elements in these sections. Therefore, this study aims to develop accident forecasting model in complex linear roads and to clarify major elements affecting traffic accidents. The results of analysis showed that the groups are divided into a group less than 355m based on curve radius of 355m, a group whose curve radius exceeds 355m and a group whose incline exceeds -0.79 and a group whose curve radius is below 355m and incline exceeds -0.79 for straight section + curved section, and for curved section + curved section, it is divided into a group whose first curved section is less than 410m based on curve radius of 410m and the first curve is turning right and a group exceeding 410m and the first curve is turning left. The major variables common in 2 models are front curve radius and curve types(left, right), road surfaces, weather.

The causes of accidents occurring in chemical plants vary, but 96% of industrial accidents occurring worldwide are caused by workers' unsafe behavior. The International Labour Organization (ILO) has announced 20 elements of workers' anxiety-warning behaviors that occur on multiple occasions at industrial sites in order to warn them of the risk of accidents caused by workers' anxiety-driven behavior, and to prevent industrial accidents, workers' anxiety-driven behavior should be controlled under stress In this study, major types of unsafe behavior were analyzed on the basis of information on the accident investigation history of domestic workspaces in order to find out how workers can manage their unsafe behavior. Based on the results of the analysis of the major anxiety war behavior, the root cause of causing anxiety war behavior was analyzed using the Swiss Cheese Model, and each root cause management method was proposed.

Article 79 of the Occupational Safety and Health Act mandates franchise headquarters with over 200 franchises to implement industrial accident prevention measures. Notably, the franchise business information provision system designates restaurants and wholesale/retail as the primary categories for information disclosure, with convenience stores classified as secondary. This study aims to identify law-regulated franchise headquarters and franchises and analyze industrial accidents within these sectors. Furthermore, it seeks to investigate adverse risk factors for individual processes across major industries. Pertinent franchise headquarters and franchises were discerned using the Fair Trade Commission's business information system. Data regarding the status of industrial accidents, as published by the Ministry of Employment and Labor, was leveraged in the analysis of industrial accidents. Additionally, a survey was conducted to derive detrimental factors for each process in major industries. The inquiry revealed a total of 7 wholesale and retail franchise headquarters subject to the law, along with 126 within the restaurant industry. Overall, there were 50,488 franchises in the wholesale and retail sector, and 71,283 in the restaurant business. Risk factors and improvement measures for industrial processes were determined for five industries: convenience stores, Korean food restaurants, coffee places, pizza eateries, and chicken vendors. Locating the currently developed safety and health program establishment guide proves to be challenging. Moreover, utilizing it can be difficult due to the industry-specific content, further complicated by the prevalence of franchise stores featuring numerous small businesses. Therefore, this study highlights the imperative need to develop guidelines that incorporate preventive measures tailored to each industry.

Most of the vehicles currently under development and in operation are equipped with various IoT sensors, but some of the factors that cause car accidents are relatively difficult to detect. One of the major risk factors among these factors is black ice. Black ice is one of the factors most likely to cause major accidents, as it can affect all vehicles passing through areas covered with black ice. Therefore, black ice detection technique is essential to prevent major accidents. For this purpose, some studies have been carried out in the past, but unrealistic factors have been reflected in some parts, so research to supplement this is needed. In this paper, we tried to detect black ice by analyzing color images using the CNN technique, and we succeeded in detecting black ice to a certain level. However, there were differences from previous studies, and the reason was analyzed.

This study was done to define nursing diagnose and to test the validity of the characteristics for patients with cerebrovascular accidents being seen at home by home health care nurses. This study was a descriptive study. The sample consisted of 10 experts(professors and home health care nurses) who had had a variety of experience using nursing diagnoses in clinical practice, and 336 nurse progress notes for 18 patients with cerebrovascular accidents. First, 32 nursing diagnoses were defined by the analysis of 336 nurse progress notes, and ten nursing diagnoses were selected according to a criteria of frequency and four nursing diagnoses from home health care clinical practice. Second, content validity was examined by an expert group which considered the sign / symtoms of the fourteen nursing diagnoses. The instrument used for this was a checklist for sign / symtoms based on the nurse progress notes and literature : Carpenito(1993), Kim Cho Ja et al (1994), Lee Sun Ok et al.(1994), Kim Mae Ja et al. (1992), Seoul University Hospital (1993) , Kim Mi Ja et al. (1991). The data were collected from March 1995 to April 1995. Data were analyzed using Content Validity Incidence where if 80% or more of the expert group agreed, characteristics were defined as a major sign/symtoms, if between 50% and 79% of the expert group agreed with the characteristic it was defined as a minor sign / symtoms. The results of this study are summarized as follows : 1. Thirty-two nursing diagnoses related to patients with cerebrovascular accidents were defined. There was a high frequency for the following : 'Potential for disuse syndrome (61%)', 'Impaired physical mobility(50%)', 'Impaired skin integrity (44.4%)', Potential for aspiration(33.3%)', 'Potential for infection: respiration(33.3%)', 'Self-care deficit : bathing /hygine(27.8%)', 'Ineffective family coping(22.2%)', 'Potential for trauma(22.2%)', 'Alteration in nutrition: less than body requirements(22.2%)'. The following diagnoses were also used in home health care clinical practice : 'Anxiety in family (50%)', 'Caregiver fatigue(27.8%)', 'Ineffective treatment behavior (22.2%)', 'Ineffective Levin tube management and Levin tube feeding(22.2%)'. Fourteen nursing diagnoses were selected. 2. Ten of the nursing diagnoses for patients with cerebrovascular accident were listed as nursing diagnoses by NANDA but four nursing diagnoses were new nursing diagnoses used in home health care clinical practice. 3. Characteristics of the ten Nursing Diagnoses from NANDA were developed from the sign /symtoms in the literature and in the nurse progress notes. These characteristics was verified as major or minor sign / symtoms by the expert group. 4. Characteristics of the four nursing diagnoses used in home health care were not defined by the literature but only by the nurse progress notes and verified as major or minor signs /symtoms by the expert group. On the basis of the findings of this study, the following recommendations are made : 1. Continual study is necessary to identify other signs /symtoms not verified in this study. 2. It is necessary to use verified signs /symtoms in home health care clinical practice. 3. It is necessary to define related factors which define each diagnoses in this study. 4. It is necessary to develop of standardized nursing are plans which include defined signs and symtoms. 5. It is necessary to study the outcomes of the standardized nursing care plans.
