As various social problems occur due to increasing traffic accidents, the government has setup and executed strong safety policies. As a result, the number of traffic accidents and the death toll have been decreasing in recent years. However, the setup and execution of the various policies for reducing traffic accidents cost much, so it is necessary to evaluate the cost-effectiveness of each policy. In the present study, enforcement by means of an unmanned over-speed enforcement system, the enforcement effect of which was proven good compared to the cost required for traffic enforcement, is compared with enforcement by policemen. As a result of the comparison, the average speed was 82.66 km/h before the use of unmanned systems and policemen; the average speed with manned enforcement was 70.57 km/h; and the average speed with unmanned systems was 67.85 km/h. The speed limit violation rate was 65% before the use of unmanned systems and policemen; 32% with manned enforcement; and 15% with unmanned systems. Considering the kinds of vehicles, the average speed and violation rate were highest among private cars, then vans, and then trucks.. Considering lanes. The accident rate was estimated based on the above results, and the input cost-to-advantage was estimated. The annual cost-to-advantage was estimated by comparing the above estimated values with the conditions before the unmanned over-speed enforcement system. Subsequently, the enforcement by policemen showed a negative advantage of 76,130,590 won, and the enforcement by the unmanned system showed a positive advantage of 38,577,670 won.

The cultured tuna production which has suddenly expanded at the short time and the demand for it attract attention. Farming mode, distribution transactions, change of the market (domestic and international) and the price trend are reviewed from the Japan's position which is the biggest consuming country. This paper tries to describe the current status of the food system related to the cultured tuna. Japanese government began the development of the tuna culture technology in 1970. It was by the Fisheries Agency's project. Kinki University which is the large scale private university in Japan participated in the project. After that, 32 years have passed. Kinki University established the full farming of the bluefin tuna in August, 2002. On the other hand, in 1974, one Japanese private enterprise began its tuna farming business in Canada. Kinki University gave this company technical cooperation. Also, in the early stages of the 90s, as for the policy of the overseas fishery cooperation foundation, it supported the tuna farming business in Australia. It is very clear to understand that the long-term technological-development has supported the take-off scene of the tuna culture business not only in foreign countries but also in Japan. The total shipment scale of the cultured tuna expanded very much within about 10 recent years. However, the decrease of the wild tuna catch, the reinforcement of the fisheries regulation and the tuna body to dwarf are remarkable now. Under the condition as the mentioned above, Japan's tuna consumption, especially, in the market at the fatty meat of tuna of the cultured tuna is building up firm status. At present, the Mediterranean Sea coastal countries, Australia, Mexico and Japan have the tuna farming sites. Australia farms the southern bluefin tuna. The others do the bluefin tuna. About for 3 years, Japan farms the juvenile of the tuna. The global production areas are as follows. 8 coastal countries of the Mediterranean Sea; 18,000 tons (61 % of the cultured tuna quantity in foreign countries), Mexico; 4,500 ton (15%), Australia; 7,000 tons (24%). In 2003, Japan has 32 managements and 39 offices for tuna farming. In Japan, Kyushu and Okinawa district, the share shows itself as 80 % of the domestic production quantity. Especially, the share of Amami-oshima Island in Kagoshima Prefecture exceeds 60 %. Therefore, this island has the maximum production scale of Japan. The amount of supply of BT and SBT was 56,000 tons in 2004. In Abroad, the tuna farming business forms a fixed connection between the importer and the wholesaler which have their office in Japan. In the field of the capital composition, the payment in advance, transaction and the way of settlement, each maintains their fixed relation. The market conditions of the cultured tuna are supported by "the decline of price level" and "the expansion of the general public consumption segment". These lead a team merchandising, and it is supported by the fixed business connection of each. This makes the profit of each business which are on the cultured tuna distribution. However, they have competition on the power balance among them.

The labor contract Law has been prepared as an important solution for social stability. After long disputes around the orientations of the law, On June 29, 2007, the new Chinese labor contract law is passed. This law reflects the changing labor relations because of economic reforms like restructuring of the state-owned enterprises and so on. This law contains more market-oriented clauses that are supplemented by corporatist scheme supported by trade unions than the first draft. This law emphasize labor's rights and interests to remove prior labor contract problem. So Chines government see this law as standard law to restructure social relationship and also require firms to corporate social responsibility. Therefore, implementation of the new Chinese labor contract law bring about increasing labor cost, infringement of autonomy for human resource management, rigidity of industrial relations. Under these situation, Korean shipping and port logistics companies need to introduce management system of minimized employment, prepare human resource management in response to long-term employment, maintain favor relationship with trade union, and set up counteiplan about risk of a labor dispute.

Vacant houses are increasing across the country, but the appropriate measures have not been set up yet. Accordingly, vacant houses are left unattended for a long time, and become deserted to degrade the residential environment. They are often used as the space for the deviation of youth or even for crimes, threatening the safety of rural society. Vacant houses are not only personal properties but also public assets that form the residential environment of a town. Therefore, the problem should be better taken care of with appropriate policies. In this study, the present situation of vacant houses in Korea, the causes of the vacant house and the limits and lessons of the improvement projects were reviewed, along with the vacant house improvement systems in the UK and Japan. The most significant difference between the cases in Korea and other countries are the method of vacant house improvement. In terms of policies and support, Korea focuses on demolition, whereas other countries focus on reuse. In addition, the vacant house improvement projects in Korea are performed mostly by government agencies, whereas local governments and private organizations in other countries cooperate to improve vacant houses and go beyond mere residential environment improvement towards the local revitalization. Based on the study results, the following are proposed to efficiently improve and use the rural vacant houses. First, the Rearrangement of Agricultural and Fishing Villages Act, which allows the vacant houses to be left unattended and not improved, should be revised. Second, the intermediate support organizations that connect the demand and supply should be fostered and supported so that the use of vacant houses can be vitalized and privately led. Third, the best practices of using the vacant houses should be found and promoted, and the vacant house remodeling technique should be developed and propagated. Fourth, a special law should be enacted to comprehensively plan, support and execute the vacant house improvement, as in Japan. Finally, the value of the vacant houses as public properties should be shared in public so that all citizens can participate in addressing the vacant house issue to derive the detailed plans to solve the problem.

Purpose: Recently, social interest in an organized trauma system for the treatment of patients has been increasing in government and academia and the establishment of trauma center is being considered across the country. However, establishing such a system has not been easy in Korea, because enormous experiences and resources are necessary. The objectives of this study were (1) to estimate a trauma patient's demands during the course of treatment and (2) to provide appropriate direction for trauma centers to be established in Korea. Methods: The records of 207 patients who were admitted to the Department of Trauma Surgery in Ajou University Medical Center due to trauma were retrospectively reviewed for a 1 year period from March 2010 to February 2011. Patients were reviewed for general characteristics, number of hospital days, numbers and kinds of surgeries, numbers and kinds of consultations, ISS (Injury Severity Score) and number of patients with ISS more than 15. Results: All 207 patients were enrolled. The average number of hospital days was 36.7 days. The ICU stay was 15.9 days, and the general ward stay was 20.8 days. Admitted patients occupied 9.02 beds in ICU and 11.80 beds in the general ward per day. The average number of surgeries per patient was 1.4, and surgery at the Department of Trauma Surgery was most common. Number of consultations per patient was 14.23, and consultations with orthopedic surgeons were most common. The average ISS was 18.6. The number of patients with ISS more than 15 was 141 (61.8%) and the average number of patients treated per trauma surgeon as a major trauma patient was 94.3. The number of mortalities was 20, and the mortality rate was 9.7%. Conclusion: To reduce mortality and to provide proper treatment of patients with major trauma, hospitals need some number of beds, especially in the ICU, to treat patients and to prepare them for emergent surgery. An appropriate number of trauma surgeons and various specialists for consultation are also needed.

For government and public institutions, civil complaints containing direct requirements of citizens can be utilized as important data in developing policies. However, it is difficult to draw accurate requirements using text mining methods since the nature of the complaint text is unstructured. In this study, a new method is proposed that draws the exact requirements of citizens, improving the previous text mining in analyzing the data of civil complaints. The new text-mining method is based on the principle of Co-Occurrences Structure Map, and it is structured by two-step association analysis, so that it consists of the first-order related word and a second-order related word based on the core subject word. For the analysis, 3,004 cases posted on the electronic bulletin board of Busan City for the year 2016 are used. This study's academic contribution suggests a method deriving the requirements of citizens from the civil affairs data. As a practical contribution, it also enables policy development using civil service data.

While Korea has actively discussed the fields of comics and animation, with an aim toward public art and publicity for cultural welfare, research on public cultural content for the underprivileged and their regions is in fact lacking. The Korean government has also tried to improve Korea's cultural welfare, but its benefits have failed to be evenly given to the underprivileged. Therefore, we need to take greater interest in the underprivileged and their regions. Korea should work to correct the unbalance among regions in the field of cultural welfare (cultural differences between the capital area and other regions, and between new towns and old), as well as improve the living environments of isolated areas. For this reason, such a public art project should be conducted from two directions. First, the underprivileged living in poor conditions should be allowed to live in clean and cultural environments. And second, public art, comics, and storytelling through animation should be formed with an eye on urban culture. This project aims to focus on improving "the quality of citizens' lives" through creating the unique characteristics and landscape of the city. It will be presented through the use of public art, which presents the elements of the city with charm and vitality. The two directions stated above are our urgent tasks. Public art, comics, and animation storytelling regarding the history, culture, and natural resources of the region will develop with the affection and pride of the citizens, and public art will help create an environment that allows people to discuss their issues. In addition, it will be cultural environments that will allow all citizens to enjoy beautiful streets and events. This project will be an opportunity to realize cultural democracy by pursuing social values such as publicity, communication, equality, and participation.

The purpose of this case study is to analyze the environmental and sociological impacts on a golf course construction at the damaged area of a previous limestone mine. Due to a long term of the open-pit mining, that site had been abandoned with geographical and ecological destruction before it was renovated to Ostar Danyang public golf course. This study is focused on the review of restoring the ecosystem through golf course construction procedures. Literature surveys of restoration through golf course construction in Japan and Canada were analyzed the procedure of utilization of previously existed lime mine. The sociological and environmental changes before and after construction were compared and analyzed. Environmental impacts on geographical, animal and plant ecology, and water quality were not affected or significantly improved after golf course construction from the mining site existed before. The local economy was also improved by increasing employment of resident and tax payment to local government. The construction of golf course could be one of the typical alternatives of ecological restoration of abandoned lime mine. Moreover in this project, minimizing the environmental impacts on surrounding ecosystem was emphasized by a larger size of developing construction. The harmonious lay-out on nature and artificial landscape were also considered a very first stage of construction procedure.

According to an annual industrial accident report from Ministry of Employment of Labor, among the various types of accidents, the number of accidents from construction industry increases every year with the percentage of 27.56% as of 2014. In fact, this number has risen almost 3% over the last four years. Currently, among the industrial accidents, heavy machinery causes most of the tragedy such as collision or narrowness. As reported by the government, most of the time, both heavy machinery drivers and workers were unaware of each other's positions. Nowadays, however when society requires highly complex structures in minimal time, it is inevitable to allow heavy construction equipments running simultaneously in a construction field. In this paper, we have developed Approach Detection System for excavator in order to reduce the increasing number. The imaged based Approach Detection System contains camera, approach detection sensor and Around View Monitor (AVM). This system is also applicable in a small scale construction fields along with other machineries besides excavators since this system does not require additional communication infra such as server.

Crimes must be reduced not only because of the financial, physical, and emotional damages they bring to the victims but also because crimes increase social costs by elevating distrust in society and instilling fear. With the increasing number of crimes in Korea, finding other factors that affect the occurrence of crimes is needed beyond the current viewpoint for crime analysis. Social support factors can be candidates for studies on the social support effect on crime occurrence in their initial stage. In this study, we identified the effect of social support factors on crime occurrence or deterrence, none of which has been considered important until now, given the emergence of spatial econometrics. The resulting Moran's I values revealed the existence of a spatial autocorrelation in all three crimes: heinous crimes, theft, and violence. As shown in the analysis using spatial econometrics and ordinary least squares, social support from families is significant in reducing all crimes especially violence. Social support from the local government is significant in preventing only theft. The spatial econometrics model is only valid in heinous crimes. These different effects of social support factors and spatial factors on crime occurrences are caused by the different characteristics of crimes. Hence, policymakers should consider the social support effect when they establish policies related to social housing or welfare.
