In spite of many previous studies conducted to prevent safety accidents at construction sites, the frequency of safety accidents has not decreased. And recently, a lot of research has been done to analyze the causes of the accidents resulting from the personal characteristics and behaviors of managers or workers, and eliminate them. However, despite these efforts, safety accidents occur consistently as managers and workers shift their responsibilities for the safety accidents onto someone other than themselves. Therefore, in order to prevent safety accidents, this study investigated the consciousness of shifting responsibility among managers and workers and analyzed the correlation between factors influencing the consciousness of shifting responsibility. In addition, it proposed the quantitative levels of the consciousness of shifting responsibility based on the survey of managers and workers. The results of this study demonstrated that managers tend to the shift responsibility onto workers, whereas workers the shift responsibility onto managers. It was additionally demonstrated that there is a correlation between the consciousness of shifting responsibility and the factors influencing it. The findings of this study are expected to improve the safety awareness among managers and workers and make contributions in the theoretical and practical aspects of construction safety management.

The purpose of this study is to understand the causal relationship between the safety behavior of delivery man and safety awareness, work environment, and occupational stress, to derive factors for enhancing safety behavior, and to manage them with priority. It seeks to provide basic data on the factors. In this study, with the help of a community site for delivery man, we conducted a questionnaire survey of a total of 119 delivery man working at distribution centers. Questionnaires were created using safety behavior, safety awareness, work environment, and occupational stress measurement tools created using survey questions from other studies. As a result of the analysis, there was a significant difference between safety education and the experience of accidents associated with working period. In addition, there was a significant correlation between safety behavior due to conflicts related to occupational stress, safety awareness and safety behavior, and safety behavior due to the safety system in the work environment. As a result, we investigated whether it was an accident and the factors that influence safety behavior, and concluded that appropriate improvements were needed.

Various social problems such as traffic congestion, car accidents and environmental problems(air pollution, noises etc.) have been happening in the Seoul metropolitan area that has the car oriented traffic system providing cars continuously. Along with this, the financial burden caused by current oil price anxiety made paradigm shift from caroriented to public transportation-oriented. Its typical example is an arterial branch bus system changing(bus lane through the center of main road) started in Seoul in July, 2004. But study on safety analysis of bus lane and characteristic of accidents are not sufficient enough to now. The bus lanes are expanded to provide roads for better traffic operation and accidents between buses and pedestrians or ordinary vehicles are considered main problems. This study divided each bus route of median bus lane(bus-only lane through the center of main roads) and bus lane at roadside by intersection and collected and analysed data about influence variables of bus accidents chosen in each section. We constructed a logistic model using collected data. As a result, bus lane at roadside are used by both buses and other kinds of vehicles differently from median bus lane and showed such characteristic in accident influence. Therefore access management to factors causing conflict and improvement of operation management are required. In case of median bus lane, the more buses moving general vehicle lane and traffic volume of section were, the more accidents happened. In case that stop line of center lane is not backward, view blocking of vehicles turning left caused accidents.

Background: The aim of this study was to analyze the interaction between neck and/or wrist pain and hand grip strength (HGS) and to investigate factors (age, sex, neck disorders, and carpal tunnel syndrome) influencing the HGS of industrial quality proofing workers (N = 145). Methods: Standardized questionnaires [Neck Disability Index (NDI), Boston Carpal Tunnel Questionnaire] were used to evaluate existing neck and/or wrist pain. HGS measurements were performed in different wrist positions. Results: Significant differences between participants with and without neck pain were found in different wrist positions, in neutral wrist position right [without neck pain (n = 48) 46.34 (43.39 - 49.30); with neck pain (n = 97) 38.46 (36.20 - 40.72), F_(1,144) = 16.82, p < 0.001, ŋ_p² = 0.11] and left [without neck pain 44.06 (41.19 - 46.94); with neck pain 37.36 (35.13 - 39.58), F_(1,144) = 12.70, p < 0.001, ŋ_p² = 0.08]. A significant difference between participants with and without wrist pain was found for neutral wrist position right [without wrist pain (n = 105) 42.53 (40.37 - 44.70); with wrist pain (n = 40) 37.24 (33.56 - 40.91), F_(1,144) = 6.41, p = 0.01, ŋ_p² = 0.04]. Regression analysis showed significant results especially for steps two (age and weight, NDI) and three (age and weight, NDI, Boston Carpal Tunnel Questionnaire) for neutral position right (R² = 0.355, R² = 0.357, respectively). Conclusion: Neck pain has an impact on HGS but should be evaluated in consideration of age and sex.

What to analyze cognitive works that are involved in ship navigation is a basic work to make alternatives for maritime safety such as development of bridge equipments, extraction of potential human errors and development of education/ training methods. In the domains in which much research on the human error has been performed such as aviation and nuclear plant, analysis methods for cognitive work analysis have been developed and applied to them. However, the research on the cognitive work analysis is not sufficient in the maritime domain. This paper proposes a method to analyze cognitive work of ship navigation. The method was developed so that some maritime characteristics and a variety of factors influencing cognitive works are reflected on cognitive work analysis processes. On the other hand, an ship collision accident was analyzed by the proposed method as a case study.

This descriptive study was aimed to identify factors which influence safety performance through evaluation of nurse's perception of patient safety culture and safety control in general hospital. Self-administered web surveys were conducted by 342 nurses who employed in general hospital from May 09 to May 13, 2014. Data were analyzed using the SPSS/WIN 21.0 statistical program. The results of analysis revealed that the score of safety culture perception was 3.34, safety control was 3.50, safety performance was 3.53 and all scores were higher level than usual. There were significant positive correlation between safety performance and perception of patient safety culture, safety control (r=.463~.645, p<.001). The positively influencing factors of safety performance are marital status, frequency of accident reports, general perception of patient safety and safety control. Explanation ratio of the variables for the safety performance was 52.0% in this study(F=4.252, p=.004). This study findings suggest that it would be useful as a preliminary report of nurse's intervention strategy through confirmation of the nurse's positive effect to improve safety performance in general hospital.

The primary goal of this study was to investigate factors affecting job satisfaction of injured workers who returned to work. There are two types of injured workers' returning to work returning to pre-injury job and getting a new job. After separating the two types of workers we conducted the multiple regression analysis on the data from the Workers'Compensation Insurance Panel of the Korea Workers' Compensation and Welfare Service Corporation(2014). The sample consisted of 1,333 occupationally injured workers who were finished with medical treatment(693 workers returned to previous work place, and 640 workers found new work places). Main results are as follows. First, injured workers who got new jobs were vulnerable to sustainability to job, work status, average monthly wage as well as job satisfaction compared with injured workers who returned to pre-injury job. Second, gender, educational level, skill fitness, average monthly wage, welfare benefits, family income/leisure life/residential environment/social relation satisfaction, and maintenance of relation with business owner during medical care were related to job satisfaction of injured workers who returned to pre-injury job. Third, gender, work status, skill fitness, continuous work possibility, average monthly wage, family income/leisure life/social relation satisfaction, substitute worker for assigned task during medical care and maintenance of relation with business owner during medical care affected on job satisfaction of injured workers who got new jobs. Based on these findings implications for policy and interventions were discussed in regards to job satisfaction of injured workers.

Longitudinal tunnels are defined as tunnels with length of over 1km. Because of Korea's topographical conditions and as safety measures for linear design, many tunnels are inevitably being constructed in Korea. The number of longitudinal tunnels constructed on expressways amounted to 104 as of the end of 2010 with a total length of 192km. Given the increasing demand for tunnels and the increasing length of tunnels, a safety evaluation of longitudinal tunnels needs to be conducted. As such, this study selected design elements, transportation environment and delineation system as elements to check and tried to determine factors influencing road crashes. For this, tunnels have been classified based on history of crashes; ones with crashes and ones without crashes and statistically meaningful explanatory variables were selected. By using these variables, a logit model was development in order to better grasp the factors that directly and strongly influence crashes. The result, related to crashes as well as the analysis were utility tunnel interior materials of driving lane and passing lane, which are related to driver's visibility, lateral width widening to consolidate space in a tunnel, and annual average daily traffic (AADT) per lane. These results may be used in the future as analysis indicators when drawing up plans to prevent crashes in longitudinal tunnels.

In order to reduce the safety risk of forestry operations, this research was conducted to examine the suitability of chainsaw protective pants after repeated laundering, testing four different products that are currently used in hand-held chainsaw operations. Laundering was repeated 10, 20, 30, 40, and 50 times. After washing, we measured the shrinkage ratio of 17 measurement positions mostly affecting the safety of forest operations and suggested the expected safety life cycle of chainsaw protective clothes. The results showed that most of the products have only one measurement position where the standard shrinkage ratio (<6%) was exceeded after 20 washings, and that the lateral direction of measurement positions shrank more than the vertical one. The numbers of repeated launderings and measurement positions were found to be significant factors influencing the shrinkage ratio (p<0.05). In the shrinkage rates for 17 measurement positions, there were significant correlations between five of the measurement positions (a, b, g, j, and n) and the number of repeated launderings (p<0.05). Therefore, the results suggest that about 10 months would be suitable for an adequate safety lifetime for chainsaw protective pants. The relationship between the number of repeated launderings and the measurement positions will be further analyzed in detail to examine the durability of chainsaw protective pants.

Unsafe working environments slow down working speed in that it takes a lot of time to respond in case of an accident, greatly reducing the productivity of construction work. Therefore, proper safety management that does not impede the productivity of construction works is a very important factor for successful construction project. However especially in mega project, the mutual effects of safety management and productivity are complex. Therefore, this study establishes a causal model between safety management and productivity influencing factors based on effectiveness metrics, and analyzes the effect of increased site congestion due to excessive personnel input, irregular safety measures and inefficient change of work schedules. The result of this study, is expected to contribute to enhancing the competitiveness of the construction industry as the basis for establishing a safety management plan that can secure appropriate productivity.
