This paper is dealing with the effectiveness to the crime prevention by the combined security system of the private security and the public security(the Police). In the western countries the public and the private security have well co-operated each other in terms of the job distribution. But our country's The private security has not much serviced in the crime prevention. The public security system has in limited capability to prevent the crime, therefore the co-production through with the private security industry and the community network are required to prevent and reduce the crime we are facing on. The followings are the result of survey on the prevention of crime through The combined security system(co-production) of The police, the private security and the community network; 1) The private security could be a big help to the police work if the two system can be co-operated smoothly. 2) The crime prevention could be not good worked out if police work would only be in the upper level class. 3) The job satisfaction is a positive if the co-operation between the police and the private security is on well.

The purpose of this study is to compare with the general and behavioral characteristics between simple and serial arsonists using the data derived from Scientific Crime Analysis System, Criminal Filing Search System, and Crime Information Management System. The analysis and findings reported here are derived from data extracted from 160 arsonists arrested by police officer. The independent variables included such socio-economic characteristic as arsonists' gender, age, occupation, education level, and previous criminal records of arsonists, and finally the general characteristics of the scene of fire settings. The dependent variable is whether or not serial fire setter. To achieve the purpose, the analysis of frequencies and cross-tab were conducted. According to frequence and cross-tab analysis, there are great differences of the general and behavior characteristics between two groups. In the comparison of simple and serial arsonists, serial arsonists are more likely to have previous criminal records, low socio-economic status, unmarried and no cohabitants than simple arsonists. furthermore, serial arsonists are more likely to use garbage papers for fire setting in the scene of the crime, to have mental or psychological problems, and to get involved in fire setting for the psychological pleasure than simple arsonists do. The present research has some obvious limitations. First, the analysis is based only on arsonists arrested by police officers. These may be considerable differences in arsonists arrested by police officers and fire setters not arrested by them. Additional research is needed to assess the extent to which these findings would apply to fire setters not arrested by police officer in Korea. Secondly, the data in this study are cross-sectional and simple cross-tab analysis are used. Potential limitation of cross-sectional data concerns the inability to specify the changes in measures as arsonists behavioral characteristics. Therefore, further studies need to use longitudinal data and more complicate statistical techniques such as correlation analysis, multiple regression analysis, or LISREL models to specify the casual relationships between dependent and independent variables for fire settings. Even if this study has some limitations, it is meaningful in which it first investigated the comparison of simple and serial arsonists focusing on the general and behavioral characteristics between two groups in Korea.

When the primary function of private security is to protect lives and property of clients, emergency management should be included in the security service and many countermeasure services should be carried out for that purpose. In theses contexts, private security should develop and maintain a educational program to meet their responsibilities to provide the protection and safety of the clients. Conclusionally, private security industry employers in Korea has not concerned with the importance of training and education by lack of recognition and has been passive about qualified guards. And the authorities supervising and the administrating the guards has not recognized the importance of private security and has neglected the training of the guards. In theses contexts, private security should develop and maintain a educational program of emergency management to meet their responsibilities to provide the protection and safety of the clients.

Modern society has been exposed to various dangers and crimes in the process of globalization, informationization, decentralization etc. along with the development of material civilization under rapid changing societal environment. These factors are exerting a lot of effects in public security environments, as result there are gradual interest about crime and crime prevention. Realization of responsibility who take charge of social safety, from public security to private security, appears important topic at the moment. The positive point of view which private security industry is responsible to cope with security spheres instead of public security has been emerged from the reason that the public security has limitation to solve security problems for themselves. It is the time to make effort to compromise the public security and the private security industry to forecast social change and prevent dangers in the advance. In Korea, there has been close cooperation between public security and private security for decades. Strongly emerging and interesting sphere is "Private Investigation(Private Detective)" in Korea at present. There has been some proposed legislations of private investigation for decreasing burden of public security and social sympathy about possibility of private investigation system is increasing now. In this study, we focused on the introduction of private investigation system through the analysis of bill proposals for last 14 years, for instance historical aspects, contents, the differences among bill proposals. Among these, a comparison on bill proposals of the 19th National Assembly's during 2012 - 2013 were analysed mainly. We examined the importance point at issue items for introduction of private investigation system. Suggestions for introduction of private investigation system is as follows. The necessity of independent bill for developmental private investigation system is needed and the main body should be a juristic person instead of a individual for the public interest and responsibility. For the good service of private investigation and to prevent the unqualified person become a private investigator, the recruiting system and examination of private investigator should be prepared well and take into consideration anticipated problems. Also the necessity of definite jurisdiction department's appointment to divide responsibility in operation.

The private security has achieved a rapid growth by playing an important role in supporting the public security. However, there are some negative results of this rapid growth. Violence committed by the private security is the biggest problem among them. This study discuss the necessity of eradicating violence committed by the private security, present some violence cases, and find solutions to the problem resulting from the cases. If violence committed by the private security is not eradicated, advancement in the private security service industry can not be expected. This study suggests the three possible solutions: reinforcing regulations restricting violence committed by the private security; strenthening the responsibility of the private security company (employer) for supervision and management on the private security guard (employee); establishing the philosophical identity of security service.

This study aims to analysis and measure on the curriculum of security programs in Korean university as the private security system. Civil security demand social safety life by the police protection and private security system. The private security or the civil guards shows rapid growth by the social development and improve the quality of life. But the supply and training system have some limitations in spite of the high demand guard-secretary. The main role of secretaries has been to accompany superiors in order to maintain their dignity or trait. Then the secretaries are required to play additional roles of safety managers such as a security manager, a protocol manager, an intelligence manager and a protective driver in order to overcome the domestic and the international safety environment and to elevate the quality of service as a competitive work. So, the purpose of this article is to analyze current situation of civil body and security guard training industry and to seek an educational model. For that, we examine in 'Do the professional training organizations meet social demand for the body and security guards'? And, 'What kind of training has to be provide for the body and security guards'? and 'What the qualifications of the trainers'? Then, 'What are the differences in training courses between private organizations and universities'? 'Is there differences in the job placement among the trainers of private organizations and universities'? etc.. Conclusion, the social demand common curriculum for the body and security guard will be drawn from the analysis of diverse training organizations with different training courses in contents, training periods, educational value, and social aim. Then we have to a standard curriculum for the successful training education system to provide social security.

About 6.7% mortality was reported in a starry flounder (Platichthys stellatus) aquaculture farm in 2022. Most of the diseased fish showed a loss of pectoral fin, hemorrhages on muscle and gills, pale gills, enlarged spleen, and nodules on kidney. Parasites, fungi or viruses (viral hemorrhagic septicemia virus and hirame novirhabdovirus) were not detected from diseased fish. However, numerous bacteria were isolated from liver, spleen and kidney. Nucleotide sequences of the A-protein-encoding virulence array protein gene (vapA) of the bacteria showed 99.93% identity with Aeromonas salmonicida subsp. masoucida. This study is the first report of isolation of atypical A. salmonicida in cultured starry flounder in Korea.
