Large metropolitan areas in the US are distinguished by highly fragmented fiscally independent suburban municipalities and special districts. The suburban fragmentation implies the congregation of similar socio-economic groups escaped from central cities and the disparity of geographical resources among local government jurisdictions. This study examines St.Louis County suburbs as a case study for the implictions of suburban governmental fragmentation and the fiscal disparities across local governmental boundaries by analyzing their relationship with public service provision using police and public school services as examples. The distribution of fiscal resources across political boundaries, the processes which created them, and public service inequalities reproduced from the disparity of fiscal resources reveal the causes and consequences of suburban governmental fragmentation. The central part of suburban fragmentation is the segregation of public goods consumption reproduced from the disparity of local fiscal resources, and it acts as a basic geographical segregating force in the suburban spatial organization.

RUVIS(Reflective Ultraviolet Imaging System) is an effective equipment that detects the location of latent fingerprint at crime scene using short wavelength ultraviolet of 254 nm. In this study, the degree of DNA damage in biological samples was compared depending on the distance and time of processing using four commonly used RUVIS. 50% of DNA was damaged by treating 10 seconds at 10 cm distance in 3 types of RUVIS such as Police RUVIS, SIRCHIE mini light and SIRCHIE RUVIS. In addition, the degree of DNA damage was increased as the distance was closer and the treatment time was longer. It showed that short wavelength UV could cause DNA damage when used close to the samples at crime scene. Therefore, it was suggested to use RUVIS at a distance of at least 1 m. The degree of DNA damage was not significant by Polilight which used long wavelength ultraviolet of 350 nm. As a result, the choice and usage of which UV light and RUVIS were critical for detection of fingerprint and successful DNA typing.

In this study, we tested Japanese trolling lines in the Jeju fishery. This fishery simulates the natural marine environment with many seabed rocks, and has been redesigned and manufactured it to be suitable for the Jeju fishery. In order to ensure that the trolling lines were deployed at the inhabitation depth of hairtails, the conditions required for the fishing gear to reach the target depth were determined for use during the experiment. The experimental test fishing was conducted at the depth of 120 m water in front of Jeju Seongsanpo and in the offshore area of Jeju Hanlim. The fishing gear used in the test fishing is currently used in a variety of field operations in Japan. However, several problems were identified, such as twisting of the line during its deployment and excessive sinking of the main line. The fishing gear was, therefore, redesigned and manufactured to be more suitable for the Jeju fishery environment. For the fishing gear to accurately reach the target depth, depth loggers were installed at the starting point of the main line and at the 250 m and 340 m points of the line. Depth and time were recorded every 10 seconds. According to the daytime positioning of hairtails in the lower water column, the target depth of the fishing gear was set at 100-110 m, which was 10-20 m above the sea floor. At a speed of 1.9 knots and with a 9 kg sinker attached, the main fishing line was deployed and catch yields at depths of 100 m, 150 m and 180 m were recorded and analyzed. When the 180 m main line was fully deployed, the time for the hairtail trolling lines to arrive at the appropriate configuration had to be 5 minutes. At this time, the depth of the fishing gear was 16-23 m above the sea floor, in accordance with the depths at which the hairtails were during the day. In addition, in order to accurately place the fishing gear at the inhabitation water depth of hairtails, the experimental test fishing utilized the results of the depth testing that identified the conditions required for the fishing gear to reach the target depth, and the result was a catch of up to 97 kg a day.

We review the adaptation strategies of the 21st climate change in an application to sea level rise. For the development of appropriate adaptation strategies on the coast vulnerable to the sea level rise, we have to consider the issues such as where to adapt, how to adapt, and when to adapt. The coastal target needed adaptation can be found by the evaluation of adaptive capacity of the coastal zone which requires the understanding of impacts and adaptive potential of the natural and socioeconomic systems in the coastal zone. Planned adaptation options to sea level rise can be classified into three generic approaches as managed retreat, accommodation, and protection In practice, the implementation of the options requires the analysis of land use, degree of vulnerability, cost and benefit, etc, and may be combination of the options rather than one approach. In terms of the response timing, the adaptation can be grouped as anticipatory and reactive ones. Generally it is more effective to consider both anticipatory and reactive adaptations at the same time for the impacts of future sea level rise. Due to the scientific uncertainty of climate change issues including sea level rise, the adaptation processes have to be designed to deal with a series of processes such as information md awareness establishment, planning and design implementation, and monitoring and evaluation in continuity and long-term period.

The oceans are the largest body of water geographical unit in the earth. In accordance with the general said of the international law, countries on the international law must have four elements: 1) settled residents; 2) determined territory; 3) a certain degree of government organizations; 4) the sovereignty. The country's basic rights are: 1) the right to independence; 2) the right to equal; 3) the right to jurisdiction; 4) the right to self-protection. UNCLOS as the only one of the "Constitution of the Earth" on the earth, the implementation of its entry into force make about 1/3 of the world's oceans should be assigned to the coastal states, in the use and management of ocean gave the coastal states the center jurisdiction, the coastal states' jurisdiction sphere had been expanded, the power comparison among all countries in the world had new changes. The ocean territory, like the land territory, is the most major material condition of a country. The ocean's strategic status is extremely important, is the important stage of the international political, economic and military struggle, there are many disputes about the rights and interests, resources and the development and utilization on the oceans. To resolve these disputes is bound to depend on a strong comprehensive national strength, including politics, economy, science and technology, as well as the powerful marine force, in which maritime police plays an important role.

In order to reduce traffic accidents at long road sections involving high risks of traffic accidents, including tunnels, bridges or curves, the National Police Agency have decided a tentative installation and operation of an automated point-to-point speed enforcement system based on cameras at January, 2007. The first system was established at the direction to Kangreung of Dunnae Tunnel at December, 2007. Currently, the automated point-to-point speed enforcement system operates at 11 sections including eight sections on expressways and three sections on national highways. However, there have been few researches on the effects of the system upon the reduction of traffic accidents in a scientific way. To this end, this research effort was initiated to evaluate the effect of the automated point-to-point speed enforcement system on traffic safety by comparing the number of traffic accidents before and after the installation of the system using a comparison-group(C-G) method. Three-year-long traffic accident data for the expressways were collected in order to evaluate the system. As a result, the installation of the system was found to reduce traffic accidents by 49.97% in average.

This study analyzes the results of applying the ISO19030 (hull and propeller performance monitoring method) standard to an actual 178 k bulk vessel. Recently, there have been many attempts to apply various energy reduction solutions to vessels to continuously strengthen GHG reduction regulations and secure maritime competitiveness. However, it is not easy to quantitatively analyze the performance of a ship. To resolve these problems, shipping companies, marine paint companies, ship owners, and transportation associations have appointed specialists and standardized the ISO19030 (standard of hull and propeller performance monitoring method) guidelines in 2016 after three years of continuous review. The ISO19030 standard provides methods to monitor hull and propeller performance quantitatively through standardized procedures, thus allowing ship managers to arrive at informed decisions for hull and propeller maintenance, and to evaluate energy-saving solutions and ship-maintenance efficiency. The ISO19030 standard provides a method of analyzing the ship's own performance by collecting the ship's operation and agency data and correcting its environmental and operating factors. In this paper, we apply the ISO19030 standard to three actual ships and propose the ISO19030 application result and the improvement point of the current ISO19030 standard.

In this study, Private investigation in South Korea, while gone through so far of politics, the process of social change, a positive feature, without evolve, insufficient growth and security services of the business burden of national judicial institutions, detective industry international of the negative vicious circle, such as the acquisition of drop and expedient information of competitiveness is continuously induced it is a reality. It is, therefore, to the proposal, such as the following. First, it must be able to use the term "detective". Secondly, in order to verify the validity of this system, after introducing the first private sphere, in accordance with the stepwise its necessity, it is desirable to extend the operational range of the public area. Third, to have a country of qualification to private research workers, will be managed directly from the country is ideal. Fourth, we must also seek plan to specialize the designated educational institution as a commissioned education institution to institution with a faculty and facilities that are specialized. Fifth, the National Police Agency must manage and supervise the private investigation business. Sixth, the legislative form to amend the current security law, as a kind of private security, must be introduced by adding a private trillion business. Therefore, in order to complement the limitation of such studies, additional subsequent research has if it is not carried out.

The purpose of this study was to develop the entity theory on the recovering process from gambling addiction. This study focused on "What is the process of getting out of the pit of gambling addiction?" based on grounded theory methodology suggested by Strauss and Corbin(1990). The subjects of this study were 7 male gambling addicts living in Jeonbuk area. As the result of this study, a total of 97 concepts were drawn, which were classified into 28 subcategories and 16 superordinate categories. The results of analyzing the categories by paradigm showed that in the process of overcoming gambling addiction, the casual condition was 'Being cut off money; 'Losing the will', and the contextual condition corresponding to this phenomenon was 'Shame', 'Repent', and 'Wanting to die'. The core phenomenon was 'Giving up the dream of hitting the jackpot'. The intervening condition to boost this core phenomenon was 'Being helped by friends', 'Being supported by the police', 'Being led by the family', and 'Showing the willpower'. The action/interaction strategies were identified as 'Cutting off the flow of funds', 'Overcoming the temptation of gambling', and 'Diverting attention to other things', ending up 'Being conscious of family', 'Growing up', and 'Being free'. The core concept in the process of overcoming the gambling addiction was revealed as 'Being free by giving up the dream of hitting the jackpot'. The process of getting over the gambling addiction was 'The dream of hitting the jackpot being shattered', 'Giving up the dream of hitting the jackpot', 'Getting out of it', and 'Being free'. The study participants were classified into four types; 'Challenging type', 'Enjoying type', 'Showing off type', and 'Obsessive type'. This study was expected to have significance in establishing the first theory in Korea on the recovering process of gambling addict.
