The Korea Expressway Corporation announced that road casualties on expressways in 2016 were 262 deaths, a 24% decrease compared to 343 deaths in 2015, thanks to the expansion of rest areas for sleepy drivers. And the installation of large-sized banners containing strong messages such as "dozing while driving means your death" helped to reduce the casualty caused by driving while drowsy by 35% compared to that in 2015. Accordingly, this study tried to analyze the impact of public advertisements designed to prohibit dozing while driving on expressways upon drivers, and to present a direction for improvement of such public advertisements in the future. Based on case studies and library researches, the study contemplated the effects of public advertisements on expressways at home and abroad. It was confirmed that the accident rate has been higher on straight roads than on curved roads and that the framing of negative messages using provocative images or slogans on traffic accidents has been considerably effective. In conclusion, if the installation of outdoor billboards for public advertisements at rest areas for sleepy drivers is institutionalized and the systematic provision of information by road section inside and outside of vehicles via Variable Message Sign (VMS) services on expressways, outdoor billboards, or navigation services (including smartphones) is available, it would be possible to maximize the effect of the public advertisements.

In this study, the convergent relation between perception of patient safety culture and safety nursing activity was investigated to prevent safety accidents and prepare data of nursing intervention for patient safety. Nurses in B City who signed on the written consent participated in this study between February 16 and 28, 2015. A total of 266 copies were collected and were analyzed using the SPSS 20.0 program. The mean score of patient safety culture was 3.60 on a scale of 0 to 5, and safety nursing activity, 4.28. The subcategory of perception of patient safety culture, which included the accident report frequency and patient safety level positively (+) influenced safety nursing activity. Therefore, effective communications and report systems in hospitals may be necessary to enhance patient safety culture. Education programs of patient safety should be developed and provided to nurses in hospitals to enhance the levels of patient safety management and their services.

This research is the study on the comparative evaluation of SPC (Staggered Pedestrian Crossings) vs PC (Pedestrian Crossings) using risk analysis. Accident factor was elicited by survey of driver's and pedestrian's at SPC & PC. I estimated the weight of a risk of violation and a mental burden by AHP (Analytic Hierarchy Process) and compared degree of risk at SPC AND PC. In conclusion, a new alternative plan of a pedestrian crossing system, staggered pedestrian crossing which plays an important role in traffic flow, pedestrian's crossings which plats an important role in traffic flow, pedestrian's convenience and traffic safer is sager than pedestrian crossings the degree of risk used this study doesn't imply an measure of the number of accident and the rate of accident, in estimating the degree of risk of pedestrian crossings, we should analyze more data of accident, behaviors, and road circumstance to include driver's and pedestrian's violation behavior in an estimate index.

The editorials of the leading newspapers may reflect as well as help formulate the public opinions to a significant degree. Bearing this in mind, this study was carried out to provide information useful in formulating such public health policies that could practically meet the social interests and demands in health appearing in the editorials of the newspapers. This analysis covered the editorials of 5 leading newspapers such as Donga Ilbo, Chungang Ilbo, Hankook Ilto, Chosun Ilbo and Seoul Shinmoon for about 10 years from Jan. 1st, 1970 through Oct. 31th, 1979. The major findings are as follows: 1. The total number of health-concerned editorials in the five daily papers for the period was 1,768 or occupied 6.4% of the total editorials of the same sources. The increasing trend of frequnecy of the health-concerned editorials since 1976 indicates the increment of social interests and demands in health. Analysing the contents, environmental pollution received the greatest attention in those editorials, which was followed by medical affairs, environmental sanitation, and disease control in order in terms of frequency of appearance. However, there was a tendency that the interests in the environmental pollution, medical affairs and social welfare tended to increase year by year, whereas those in environmental hygiene and disease control comparatively decreased. 2. Motives of dealing with the health-concerned editorials were provided by announcement of the governmental policies and implementation for 25.6% and by out-breaks of the relevant events for 23.9%. This tendency coincides with the general characteristics of the editorials that reflect the timely issues. Closely analysing, however, the fact that the motives engendered by the out-breaks of the relevant events or by the season concerned comparatively tended to decrease as years pass by, indicates that the editorials tend more to seek the future-oriented demands in health rather than the current issue-oriented. 3. The editorials appeared to be more concerned with the governmental policies. 95.7% of all the editorials analysed were addressed to the government. This signifies the role of government in the field of public health and medical affairs. Their attitudes toward health-related policies of the government were much more negative than the other editorials that were addressed to the government in other fields. This suggests that the governmental interests in health were neither sufficient nor fair. 4. What the editorials most stressed were; (1) increment of governmental interests in health, (2) improvement of the governmental health administration, (3) enriching the basic statistics, and (4) development of various technologies pertinent to health affairs and disease control, and so forth. However, must of their suggestions were not concrete but rather abstract and conceptual. 5. The editorials also expressed strong interests in research area. The areas of the needed research most suggested by items are; (1) development of effective health care delivery system, (2) establishment of more practical system of calculating medical cost, (3) implementation of effective policies to control degenerative diseases, (4) division of medical care services and pharmaceutical services systems, (5) effective ways to prevent Co poisoning accidents, (6) changing status of environmental pollution and its effects upon health, and (7) status of occupational diseases, and so forth. 6. There were some editorials -not small in quantity -that have risk to mislead the public opinions as well as the health policies due to lack of professional knowledge of the writers. It is desirable to establish some kind of mechanism that screens the erroneous contents of the editorials to help prevent misleading opinions.

With the increased demand for membrane structures in recent years, there have been many studies of their mechanical properties, to the extent that such structures have become recognized as independent structures with a level of safety and durability comparable to those of other general structures. But in reality, the study for the maintenance of membrane structures has not been as active. In particularly, the study of watertightness from the perspective of maintenance has been very limited. Accordingly, a study on securing watertightness performance and the guidelines for maintenance is necessary. In this study, through a case study of water leakage accidents in membrane structures overseas, causes of leakage were selected from the membrane material itself, joint parts and open door of roof part in membrane structure. The water leakage and deterioration elements were analyzed from those leakage causes. The degree of importance of the water leakage and deterioration index was also designated using the AHP (Analytic Hierarchy Process) method. As a result, the basic technical index was suggested for the maintenance of the roofs of large-span membrane structures to prevent water leakage. This index will be used to make a guideline for the long-term maintenance of the roofs of large-span membrane structures.

The construction industry has the most safety accidents of any of the domestic industries. Special care must be taken because disasters in the construction industry lead to social problems caused by huge property losses and casualties. As a result, there is a growing awareness of disasters occurring in the construction industry, and government departments are tightening their regulations on safety management. In particular, the OSHA (Occupational Safety and Health Agency) focuses on the expansion of protection targets and the clarification of responsibility in the full amendment OSHA. As a result, a study that focuses on the client's responsibility for safety management is needed. In this study, the project performance capability assessment of construction project management contractors, which is being carried out with uniform assessment criteria without considering the characteristics of the construction project, is considered and all the amendments to the OSHA are considered, and the factors were derived for improvement measures.

A study survey about the rice cake producers completing the food hygiene education in Korea was investigated by characteristics of the rice cake business. The difference between their online and offline awareness of food hygiene education were compared. The average age of rice cake producers is 50 (40.1%), with a high school education (52.6%), 10-20 years of service (34.3%) showed the highest percentage. In relation to sales and work area, workshop personnel are engaged in two (79.5%), An area of less than $99.17m^2$ (92.0%), rent (60.2%) with most paying a monthly rental amount of less than 1 million won (54.8%). There were 228 accident cases in three years (an annual average of 2.4%), manufacturing, Processing the item number was less than 20 types of analysis (86.7%). Case of food hygiene education graduates are women, the lower the age, the higher the education level, was preferred online. Online education was chosen because of 'time, economic, convenience'(73.7%). Online graduates have recognized that health education is more conducive to business. There was no significant difference between the sales online and offline graduates. For hygienic management response was that online graduates are well above the 7.4% offline graduates. Online and offline graduates 60.7% appeared to be more satisfied than the previous training institutions.

In semi-transverse ventilation system applied for road tunnel, adjustment of the port opening ratio is an essential part for uniform airflow rate per unit length over the entire tunnel. However, it has not been considered decently throughout the design process and operating of the tunnel. Therefore, in this study, we developed a program for the calculation of the opening size ratio of supply or exhaust port in transverse ventilation system and carried out the research to present a management plan for the port. In supply duct system, the opening size of the port had a tendency to increase and then decrease later when it gradually becomes closer toward the bulkhead at the beginning of the duct the minimum opening degree is to appeared as 56%. In the exhaust system, port size is the smallest at the beginning of duct as 15%, has shown a tendency to increase towards the bulk head. As results of estimating the air flow rate for 300 m intervals, the exhaust flow rate in the center of tunnel appeared to be extremely low as 8.1% and 12.5% when port size is constant and is adjusted supply type. Thus, even if the normal ventilation efficiency is declines, yet it is highly recommend adjusting the port size in order to obtain a uniform flow rate at fire accidents.

In ports of Korea, the marine traffic flow is congested due to a large number of vessels coming in and going out. In order to improve the safety and efficiency of these vessels, South Korea is operating with a Vessel Traffic Service System, which is monitoring its waters for 24 hours. However despite these efforts of the VTS (Vessel Traffic Service) officers, collisions are occurring continuously, the risk situation is analyzed that occurs once in about 20 minutes, the risk may be greater. It investigated to reduce these accidents by providing a safety standard for collision danger in a timely manner. Thus, this study has developed a risk prediction module to predict risk in advance. This module can avoid collision risk to adjust the speed and course of ship using a risk evaluation model based on ship operator's risk perspective. Using this module, the ship operators and VTS officers can easily be identified risks in complex traffic situations, so they can take an appropriate action against danger in near future including course and speed change. To verify the effectiveness of this module, this paper predicted the risk of each encounter situation and confirmed to be capable of identifying a risk changes in specific course and speed changes at Busan coastal water.

Fishing vessel insurance of National Federation of Fisheries Cooperatives indemnifies the assured against marine losses by reason of maritime perils, that is to say, perils of the seas, sinking, stranding, collision, extraordinary action of winds waves and fire, damage, salvage. Therefore this insurance is a rational protective measures for preserving fishermen's property by the exposure to maritime perils. But there may be some problems on the perils covered by fishing vessel insurance clauses bemuse these clauses are not clearly and accurately prescribed in part. Especially where the assured may claim payment from fortuitous accidents or casualties of the seas musing the loss, they used to raise a question in argument about the ambiguity of these clauses. So these problems may need to be reformed for the purpose of preventing or decreasing those of the assured, the fishermen. After drawing out some problems on the perils covered by fishing vessel insurance clauses, this thesis will suggest the improving schemes on the perils covered by these clauses.
