Recently, the increase of international trade volume is leading to risk exposure and safety accidents in the port terminal industry. In addition, as Serious Disaster Punishment Act came into effect on January, 2021, various guidelines and laws to protect safety and life in port terminals are being enacted. However, despite these efforts, medium-to-large safety accidents in the port terminal industry have occurred. According to the Korea Occupational Safety and Health Agency, from 2016 to 2019, the number of casualties in the port handling industry increased by 4.2%. To build some effective follow-up management of port accidents and preparation of related safety laws/systems, a risk analysis in consideration of causes and damage of accidents should be conducted. Therefore, in this study, major risk factors and preventive measures were derived by conducting risk assessment based on 1,039 cases of port terminal accidents collected by the Korea Occupational Safety and Health Agency for five years. Priorities for preventive measures were then determined through IPA analysis, Borich needs analysis, and The Locus For Focus analysis.

This study aims to analyze an influence of industrial accident on industrial productivity. We analyzed relationship among industrial accident, labor force, and industrial productivity using vector error correction model (VECM). The data used in the analysis were the number of industrial accidents, the number of workers, and index of all industry production from January 2008 to June 2017 in Korea. Finally, the industrial accidents have played a role in reducing labor force and industrial productivity.

Objectives: We examined the association of hearing with cardio-metabolic diseases, dyslipidemia, hypertension and diabetes mellitus according to the personal and occupational characteristics of workers exposed to noise. Methods: The subjects of the study were 237,028 workers who underwent 2, 3, and 4 kHz airway pure tone audiometry in 2015 and who underwent clinical tests to diagnose cardiovascular-metabolic diseases. Cardiovascular-metabolic diseases were defined using reference values for respective items including blood pressure (systolic/diastolic), fasting blood glucose, cholesterol, and triglycerides. The airway pure tone hearing threshold of 2, 3, and 4 kHz, the average threshold of 2-3-4 kHz, and the hearing loss by the average threshold of the primary examination were distinguished. Results: Workers with cardiovascular-metabolic disease had significantly higher average hearing thresholds and higher rates of hearing loss. Logistic regression analysis, which adjusted for demographic variables of gender and age and occupational variables such as workplace size, industry, and type of work, and cardiovascular-metabolic disease as independent variables, showed that the odds ratio of hypertension to hearing loss in the mid-frequency was 1.239 (95% confidence interval: 1.118-1.374). For hypertension was 1.159 (1.107-1.214) and for diabetes it was 1.166 (1.104-1.230) for hearing loss in the high-frequency. Hearing loss measured by mean hearing was 1.178 (1.105-1.256) for hypertension and 1.181 (1.097-1.271) for diabetes. Conclusions: Cardiovascular-metabolic diseases in noise-exposed workers are associated with an increased risk of hearing loss and should be accompanied by bio-monitoring of cardiovascular-metabolic diseases in addition to auditory surveillance.

The recent increase in international trade volume and explosive increase in cargo volume due to the non-face-to-face society are leading to an increase in risk exposure and safety accidents in the port logistics industry. Consequently, as the atmosphere and consensus on safety are spreading throughout the society, various safety laws are being enacted by the industry. Nevertheless, according to the industrial accidents status analysis by the Ministry of Employment and Labor, the average annual number of injured persons increased by 11.1% and the number of deaths by 4.0% from 2015 to 2019. This means that special attention should be paid to possible future risks and preventive measures for major causes of accidents should be established. Therefore, in this study, risk assessment was conducted based on 5,028 accident cases that were reported by the Korea Occupational Safety and Health Agency for 5 years, from 2016 to 2020, and major risk factors for each industry were derived, and then bow-tie analysis was conducted to perform the risk assessment; Further, the study aimed to derive the causes and preventive measures from the risk factors.

This study analyzed the recent serious disaster cases of chemical extinguishing agent poisoning and suffocation investigated by KOSHA and proposed the safe use of chemical substances, including the chemical extinguishing agent. An analysis of the statistical figures an increase in the number and variations of chemical poisoning and suffocation cases in industry between 2011~2016 increased. Unlike other physical accidents, chemical accidents are very high in severity and it is difficult to identify the chemical hazard and risk. To prevent chemical disasters, it is essential to develop and use an easy chemical risk assessment tool. For the safe use of chemical substances, in which it is difficult to carry out hazard identification and risk assessments, this thesis presents the useful chemical recognition and risk assessment tools, CHEM-i and CHARM developed by KOSHA.

Portable ladders are widely used as ascend and descend pathways and platforms for works at height at residential and industrial sites. In the last 10 years, 267 fatalities and 36,571 accidents related to portable ladders have been reported, suggesting a need to develop countermeasures to prevent such accidents. In this study, an in-depth focus group interview (FGI) was conducted with various stakeholders of portable ladders to survey the current usage and requirements for improving work safety. A new portable ladder called active platform ladder was developed based on the requirements suggested by the FGI. A stability test confirmed that the developed ladder is more stable than conventional ones, suggesting that it can reduce the fall accidents.

항공교통관제사와 조종사 사이의 의사소통은 항공기 운항 안전에 있어서 매우 중요한 요소이다. 국제민간항공기구(ICAO)는 민간항공운송산업의 발전과 안전 도모를 위해 조종사 영어자격능력 시험을 의무사항으로 규정하고 있다. 왜냐하면 조종사의 우수한 의사소통능력은 비상상황 또는 비정상상황을 즉각적으로 대응할 수 있는 매우 필수적인 능력들 중 하나이기 때문이다. 대한민국 국토교통부는 2006년부터 ICAO EPTA 시험을 민간항공운송에서 조종사 의무자격시험으로 법적으로 규정하고 산하기관인 교통안전공단을 통해 시험을 주관하고 있다. 본 연구는 EPTA 시험에 응시하는 응시자의 시험에 대한 신뢰성을 증진시키고 시험제도의 발전방안을 모색하고자 하였다. 이를 위해 본 연구는 첫째, EPTA 시험제도와 관련한 이론적 배경을 고찰하였다. 둘째, EPTA 시험제도의 국내에서 정착 및 발전과정을 살펴보았다. 셋째, EPTA 시험제도의 신뢰성증진 및 발전방안 모색을 위해 총 15명의 항공전문가들을 대상으로 질적 연구를 수행하였다. 본론의 질적연구를 통해 연구자들은 국외 ICAO 공식 인증 EPTA 시험결과와 국내 교통안전공단이 주관하는 EPTA 시험결과를 바탕으로 교차응시에 따른 EPTA 등급을 비교·분석할 수 있었으며 시험응시자들에 대한 인터뷰를 통해 국내 EPTA 시험 발전을 위한 개선방안을 도출하였다.

건설현장에서 작업환경측정을 하고 있으나 노출되고 있는 유해인자를 세분화하여 작업환경측정을 하지 않고 공정별 대표적으로 노출되는 소음, 진동 등 몇 가지만 실시하고 있다. 이에 건설현장에서 가장 많이 노출되는 산화규소분진의 유해성과 현재 건설현장에서 하고있는 개선대책의 보완점을 찾고자 한다. 연구방법: 안전보건공단과 산업보건협회에서 발행하는 실태조사 보고서 및 작업환경측정 기관의 자료를 활용하여 현황을 분석하였고 산업안전보건법의 작업환경측정에 관한 규칙과 비교 분석 하였다. 연구결과: 산화규소분진의 유해성을 파악하고 개선책을 보완도출하였다. 결론: 건설현장의 산화규소분진의 유해성을 도출하고 이에 따른 개선대책을 제시함으로써 현장에서 적극적으로 적용한다면 산화규소분진에 대한 직업병을 줄일 수 있을 것으로 기대된다.
