The important items, which should be considered in Private Investigation Law, can include subjects, licenses, the scope of business, qualifying examinations, and supervisory and penal provisions. The subjects of Private Investigation Law should be permitted to be both natural persons and juridical persons in terms of providing various services, but should be permitted to be juridical persons and should be administered on a license system, even in order to ensure public interests. Concretely, the introduction scope of Private Investigation Law can be regulated to include the followings: that is, investigating the whereabouts identification of runaways and missing children, investigating the personal identification, habit, way of action, motivation, whereabouts identification, real child confirmation, association, transaction, reputation, and personality of specific persons or specific groups, investigating the whereabouts identification of missing persons, owners of government-vested properties or renounced properties, investigating the whereabouts of lost properties or stolen properties, investigating the causes of fire, character defamation, slander, damage, accident, physical disability, infringement on real estate or movable property, and investigating all sorts of accidents including traffic accidents, insurance accidents, and medical malpractices. In the qualifying examination, examinees' age should be restricted to be over age 25. The person, who is exempted from its primary examination, should be restricted to be the person, who has the career of over 20 years in related fields, in consideration of its equity with other certificates of qualification. In the supervisory institution, as the policy institution is the supervisory institution in many countries including France (the police) and Japan (public security committee), so the National Policy Agency should be the supervisory institution in consideration of management aspects. In the penal regulations, especially, we should clarify the management of personal information (personal information protection, personal information management), and so should prevent the infringement of people's basic rights, and then should ensure the public interest.

The study was to investigate kinematic difference between flexed and extended type of knee during Jigeo-Cha-Gi in Taekwon-Do. For this subjects participated were consisted of weights of fin (1), bantam (1) and welter class(1) of male 3 national representative level skilled in two type(flexed and extended type) of Jigeo-Cha-Gi. 3D cinematography analysis was performed for motion analysis and Kwon 3D ver. 3.1) was used for 3D coordinates & analysis variables calculation. In Temporal variable there was no significant difference statistically in all phases & total elapsed time between flexed and extended type, but flexed type was delayed more 0.016 sec than extended type. In displacement of COG there was significant difference in level of p<.05 showing longer mean 6.13 cm in case of flexed type than extended type in displacement of COG during all phase and too significant difference in level of p<.01 showing longer mean 4.4 cm in case of flexed type than extended type in displacement of COG in follow through phase. In velocity of COG there was significant difference in level of p<.001 showing higher mean 15.53cm/s in case of flexed type than extended type in velocity of COG(Y direction) during targeting phase and peak velocity(Y) was more fast 8.74 cm/s in extended type than flexed type. In velocity of leading leg in forward direction(Y) there was significant difference in level of p<.05 showing higher thigh mean value in case of flexed type than extended type but showing higher foot mean value in extended type at level of p<.001 than flexed type in velocity of COG(Y direction). In velocity of leading leg in vertical direction(Z) there was no significant difference in the second & third phase in case of vertical velocity level, but momentum transferred efficiently form proximal to distal endpoint. In front-back & right-left orientation angle of trunk there was possibility of more stable Jigeo-Cha-Gi in extended than flexed type by decreasing in right-left orientation angle of trunk. In relative angle of lower leg(hip, knee, ankle) there was significant difference in level of p<.001 showing longer mean 32.74 deg. in case of flexed type than extended type in hip joint during the second phase but maintained insufficient extended knee of mean 168 deg. in targeting phase.

Realities of illegal fisheries in the central and southern coastal areas of the Yellow Sea were investigated. The study was based on the data released by the Ministry of Maritime Affairs and Fisheries (MOMAF) and Korea Coast Guard (KCG) during 1992-2002 and on questionnaire responses. Analyses of KCG data showed that the number of enforcements by the agency gradually decreased during 1998-2001 but rose in 2002. Analyses of the MOMAF data, however, revealed that illegal fisheries gradually increased during 1992-1996, but sharply increased after 1997, and that such illegal activities became more common in the East Sea beginning in 2001. MOMAF data also showed that although illegal fisheries began to increase in the Yellow Sea after 1997 they tended to decrease in the southern sea after 1998, with a high rate of small-bull trawlers (40.9%) that were non-sanction fisheries (38.1%). Questionnaire responses showed that illegal fisheries were mainly motivated by poverty (27.4%) and largely occurred in coastal fisheries (78.0%). Analyses of questionnaire responses also suggested that illegal fishing activities can be reduced through tougher laws regulating fisheries.

Since 2009 The Korean National Police Agency has been pushed "permissive left-turn" forward in order to making progress in Korean traffic operations system. Preceding researches manuals and guidelines present 6 standards(# of accidents # of lanes, pedestrian volume sight # of permissive left-turn lanes vehicle volume) as installation permissive left-turn. But in practical affairs it is most important that secure enough Gap-time between permissive left-turn vehicle and opposite through lane vehicle to make permissive left-turn vehicle move safer and more efficiently. This study suggests applying gap acceptance theory in microscopic model to permissive left-turn installation standards. Analysis methods of this study are field data survey statistical analysis and microscopic simulation analysis. This study collected field data by using AVI recording and measured permissive left-turn vehicle intersection passing time(T1) and against the opposite through lane vehicle Gap-time(T2). And statistical analysis performed about two values that measured before to predict the functionality between T1 and T2. These studies to overcome the limit of sample size carried out a microscopic simulation(VISSIM) plan and collect more samples to input statistical analysis.

The golden time of emergency vehicle is directly connected to the public safety. Therefore, national attention has increased to cut down the emergency vehicle's travel time. In order to shorten the intial dispatch time of it, emergency preemption system was installed at five intersections, and after test operation, whether it could be introduced in the country was estimated. We analyzed the effect of the traffic volume, emergency vehicle's travel time, and queue length under preemption and non-preemption. In the verification of the emergency preemption system, it was confirmed that the emergency vehicle's travel time was reduced from 350% to 24% compared to non-preemption system(TOD). In the saturated condition, queue length were remained 15 minutes and near saturated condition was about 30 or 45 minutes. At the non-saturated condition, the queue length's difference between emergency preemption system and general signal was small.

The purpose of this study was to explore the correlation among professional self-concept, self-efficacy and job satisfaction and to identify the effect of professional self-concept and self-efficacy on job satisfaction in general hospital nurses. Questionnaires were completed by 156 nurses who were working for one general hospital in Busan. The mean score of professional self-concept and self-efficacy were $3.02{\pm}0.23$ and $2.92{\pm}0.21$ respectively. The mean score of job satisfaction was $2.76{\pm}0.26$. With respect to job satisfaction, the correlations were .325 (p<.001) for professional self-concept and .212 (p=.008) for self-efficacy. As integrate of the study result showed job satisfaction had correlation to professional self- concept and self-efficacy. The regression model explained 12.6% of job satisfaction. Professional self-concept was factor influencing job satisfaction. So professional self-concept enhancement strategies and self-efficacy improvement programs should be developed to improve job satisfaction.

The Korea Maritime Police Agency(KMPA) is the national maritime Search and Rescuee (SAR) authority with the responsibility to promote an efficient organization of SAR services and to coordinate the conduct of SAR operations within the Korean Search and Rescue Region(SRR). The maritime SAR operations shall provide an adequate and effective search and rescue services to minimize the loss by rendering aid to persons in distress and property in the marine environment. The essence of a successful search and rescue operation is the speed with which it is planned and carried out because survivors who need assistance and whose chances of survival diminish rapidly with time. This paper aims to propose an optimal allocation model of maritime SAR fleet in view of minimizing the search and rescue time. When maritime accidents occur, rescue units have to reach to the distress scene within the specified time. For this, SAR units must be redeployed to an advanced base so that Rescue Units(RU) can reach to the scene of distress in the shortest possible time. The Korean maritime SRR is divided into 180 sub-areas in consideration of an operational and technical ability of SAR units. The suggested model is verified through an empirical application to the Korean maritime SRR. And also the Rescue Vessels(RV) required is estimated for each Rescue Co-ordination Center(RCC).

According to the accident statistics published by the National Police Agency in 2007, the number of commercial vehicle(city, suburb and other buses) accidents consumes 3.5 percent of the total number of traffic accidents in this year. Since the commercial vehicles are responsible for not only the drivers but also the passengers, it leads more serious social and economic problems. There have been various forms of systems such as a digital speedometer or a black box to meet the social requirement for reducing traffic accidents and safe driving. however the system based on the data after accident control the driver by analyze dangerous drive behaviors, so there is a limit to control driver in real-time. Also speedometer currently managed provide the driver warning information in real-time, but using only the speed of vehicle and RPM information regardless of actual dangerous drive behaviors, disappear the effectiveness. In this study performed a simulation for drivers in general using a simulator programed with dangerous driving types we had developed in the previous study and judging the types. It'd be more effective system to provide the drivers warning information using weight valued in this study. However in this study is limited to apply weight as a result of simulation of drivers in general in actual situation should be made up the deficit based on information of driving type of actual commercial vehicles.

Recently, our society has been changing its population structure due to low birth rate along with the extension of life span due to the development of medical environment and improvement of living environment. It was not long before the population became older, and the problem of the elderly was amplified by generational conflict. The current generation of senior citizens could not afford to prepare for their own retirement income due to their children's education, marriage and housing problems, and is a generation alienated from the benefits of public income security. In addition, not only are they in poverty with rapid industrialization, informatization and economic instability, but they are also threatened with livelihood. The increase in elderly crimes arising from the elderly, who are less adaptable to our society dominated by materialism, is being highlighted as a new social issue. In this study, we are going to analyze the causes of violent and violent senior citizens' crimes in quality along with quantitative growth, and present criminal situations and preventive measures using 10 years of data, judging that this is a time when a national response is needed through a social discussion on crimes committed by senior citizens in our society, where the pace of aging is unprecedentedly fast in the world In order to achieve this research objective, various opinions and statistical data of our society where the standards of senior citizens are changing were reviewed, and analysis of crimes was conducted on literature utilizing data of the Supreme Public Prosecutor's Office, the National Police Agency, and the National Statistical Office, recent press releases, and existing research materials. In this study, we will diagnose crimes committed by senior citizens in various aspects, including the characteristics of the elderly and the view of the elderly in the present society, and explore the direction of development for the prevention of future crimes as well.
