본 연구의 목적은 산업재해를 경험한 근로자의 경제활동형태 변동과 그 특성을 기술하고, 산재근로자의 노동시장이행과 관련하여 산재보상서비스를 비롯한 영향 요인이 무엇인지 탐색하는 것이다. 이를 위해 산재보험패널 1~3차(2013년-2015년)자료를 활용하여, 요양을 종료한 1,668명의 산재근로자를 대상으로 분석하였다. 연구결과는 첫째, 한번이라도 원직장 복귀를 경험한 사람은 36.9%, 재취업 경험자는 51.5%, 미취업 경험자는 36.9%였다. 경제활동형태 전이확률은 현재 원직장 복귀자가 다음 기에도 원직장을 유지할 확률은 88.1%, 재취업자의 재취업 유지 확률 88.9%, 미취업자가 다음 기에도 미취업자가 될 확률은 60.0%로 나타났다. 둘째, 경제활동형태 변화에서 재취업 대비 원직장 복귀에 유의미한 영향을 미치는 요인은 성별, 연령, 학력, 요양기간, 현재 업무수행능력, 산재전 직장규모, 근무기간, 종사상 지위 중 임시직, 일용직 그리고 직업훈련 총 횟수였다. 재취업 대비 미취업을 선택할 확률에 유의미한 영향을 주는 요인은 성별, 연령, 장해등급, 요양기간, 현재 업무수행능력, 산재 전 근로기간, 직업재활서비스 이용 경험이었다. 분석결과를 토대로 산재근로자의 직업복귀와 노동시장이행을 지원하기 위한 논의점을 제시하였다.

초고령화 사회로 진입하고 있는 대한민국 노인 인구의 상황을 반영하여 노인 교통사고의 특성을 파악하고, 이항형 변수를 활용하여 노인 보행자 교통사고에서 발생한 중상 이상의 교통사고와 경상 이하의 교통사고를 구분하여 독립변수와 종속변수의 관계를 분석하였다. 도로교통공단 교통사고분석시스템(TAAS)에서 지난 10년간('3년~'22년)의 노인 보행자 교통사고 자료를 구득하여 데이터 수집, 가공, 변수 선정을 수행하였으며, 기초 통계 및 사고 요인별 분석을 실시하였다. 로지스틱 회귀분석 모형을 적용하여 총 15개의 영향 변수를 도출하였고 노인 보행자 중상이상의 교통사고 발생 확률에 가장 큰 영향을 미치는 영향 변수들을 도출하였다. 이후, 로지스틱 모형의 정확도 분석을 위해 통계적 검정을 수행하였으며, 노인 보행자 교통사고에 영향을 미치는 변수를 도출 및 예측모형 구축에 따른 교통사고 발생확률 예측 방법을 제시하였다.

Purpose: This cross-sectional survey research was undertaken to identify the factors influencing time from onset to hospital arrival of stroke patients and to provide basic information for the development of intervention programs for stroke patients. Methods: The data were collected using a convenient sampling method from three hospitals in Inchon. The subjects were 78 patients who were diagnosed as stroke by doctor and they voluntarily participated in the study. Results: On the average, subjects arrived at the hospitals by 16.72 hours after the onset of stroke events with the range from 0.17 hours to 72 hours. Thirty-four(43.6%) subjects arrived within 3 hours which can maximize treatment effects. There was significant difference in hospital presentation time according to the level of knowledge(${\chi}^2=18.629$, p=.0003). A negative correlation was found between the hospital presentation time and self-efficacy (r= -.320, p=.004). Stepwise multiple regression analysis revealed that the most powerful predictor was self-efficacy. Self-efficacy, the level of knowledge and physical symptoms were significant factors and accounted for 21.7% of the variance of hospital presentation time in stroke patients. Conclusion: According to the results, self-efficacy is a useful concept for reducing the hospital presentation time from onset of attack in stroke patients. Therefore, nurses should consider educational programs which include not only a knowledge of stroke and recurrence prevention but also the concept of self-efficacy.

In the present study, a numerical simulation for the diffusion of hydrogen leakage of FCV(Fuel Cell Vehicle) in a tunnel was performed to aid the assessment of risk in case of leakage accident. The temporal and spatial distributions of the hydrogen concentration around FCV are predicted from the present numerical analyses. Flammable region of 4-74% and explosive region of 18-59% hydrogen by volume was identified from the present results. Factors influencing the diffusion of the hydrogen jet were examined to evaluate the effectiveness of tunnel ventilation system for relieving the accumulation of the leaked hydrogen gas. The distribution of the concentration of the leaked hydrogen for various cases can be used as a database in various applications for the hydrogen safety.

The purpose of this study is to investigate the effects of customer orientation factors in relation to medical services on the values of the service and customer satisfaction and loyalty. Those factors include patient safety and, as found by previous studies, specialization, explanation of what to be medically examined and customer orientation itself. Based on these pervious studies, this study surveyed customers of 7 general hospitals located in Busan to empirically identify relations between customer orientation factors of medical services and the values of the services and customer satisfaction. Results of the study can be summarized as follows. First, this study is very meaningful in that it established a basic theory of patient safety as one of the above customer orientation factors, and tried to empirically demonstrated the theory by applying it to medical services. Second, another of the factors, specialization was found positively affecting the values of medical services, but not affecting customer satisfaction. Customers are likely to choose specialized medical institutions even at higher cost when they undergo an accident or disease. Nevertheless, in factors, whether medical service providers are specialized is not influencing customer satisfaction. This is because medical institutions are failing to properly make recognized their specialization to customers who want to receive specialized medical services. Third, another of customer orientation factors, that is, explanation of what to be medically examined was found not having positive effects on the values of medical services and customer satisfaction. This is probably because enough time was not given for the explanation or because the explanation itself was not provided enough. Fourth, medical service providers' customer orientation was found positively influencing the values of medical services and customer satisfaction. In other words, it seems that customer-centered attitudes and behaviors of medical service providers had positive effects on customers' perception of medical services. Fifth, another of the factors, that is, patient safety was found positively affecting the values of medical services and customer satisfaction. This is probably because medical services' accurate diagnoses and reliable services had positive effects on customers' perception of medical services. Sixth, customers' perceived values of medical services were found having positive effects on customer satisfaction and loyalty. This suggests that the values of medical services are an antecedent variable that directly influences customer satisfaction and loyalty. Seventh, customer satisfaction was found positively affecting customer loyalty. This suggests that customer satisfaction is an antecedent variable of customer loyalty. In conclusion, this study showed that in relation to medical services, customer orientation factors' significant influences on the values of the services and customer satisfaction requires continuous efforts for raising customers' perceived qualities of medical services.

Tracheoinnominate artery fistula is a critical complication of tracheostomy. The most important factors influencing patient outcome are prompt diagnosis, immediate control of bleeding with a patent airway, and emergency operation with or without interruption of the innominate artery. Here, we report a case of tracheoinnominate artery fistula in a 40-year-old woman with cerebrovascular accident who was successfully managed with an aorta-axillary artery bypass.

Seafarers are one of the main engines driving economic growth in the maritime sector. The International Maritime (IMO) Organization estimated that there were approximately 1.5 million seafarers around the world engaged in international trade in 2012. Data have shown that human casualties in maritime accidents around Japan have shown an increasing trend over the last ten years. One cause is human error, which is inseparable from the human element that influences mariner's decisions and actions. The Personal Identification (PIN) Safe method is one way to systematically identify substandard and unsafe actions by considering the error taxonomies associated with various scenarios for a maritime system. The results are based on analysis of the role of the human element in commonly reported unsafe actions when interacting with equipment and other systems. Furthermore, patterns of influencing shaping factors were observed on the basis of data processing; the aim of this study was to promote safety culture and provide an opportunity to improve safety at sea.

Rail cars are subject to vibration, impact and wear which can cause severe defects leading to a fatal accident. Thus, they are designed and manufactured in consideration of such factors influencing their service lifetime. Under-frames are composed of steel and support most of load imposed on the car. Steel is very sensitive to corrosive environment and corroded even in a normal service condition. Regular maintenance can Protect steel Parts from corrosion by painting. However, an exposure of defect point to corrosive agents can make corrosion proceed to a considerable depth, which may cause the structure to remain under safety standard. It is necessary to understand corrosion behavior of rail cars in order to estimate unexpected accidents by corrosion.
