This study discusses the occupational value and the feasibility of introducing an accredited detective system that is not the only OECD country. The procedures and methods of the study were developed as qualitative research methods through review of various previous studies and case analysis in related fields. The results obtained through the study are as follows. First, detectives have various social values as public goods. It is basically a policy alternative that can improve the quality of public services and secure the soundness of national finance. This can further enhance the confidence of the people in state institutions. Second, as detectives are already legally recognized in other countries, they will be able to fulfill their social roles as new jobs through cultivation. Next, in order to advance research in the field of accredited detective systems, research based on quantitative data should be more active.

Purpose: With the diversification of modern society, it is difficult to predict crime types, and the limitations of the state's functions, such as human limitations and lack of budget, are increasing. Method: However, as the number of private investigation companies that do not use illegal means to solve the request increased, attempts were made to introduce a public detective system that would manage and supervise it and compensate for the gap in public power. Result: However, due to the nature of the Private Investigator system, legislation has not progressed as the National Police Agency and the Ministry of Justice are at odds with existing laws that guarantee existing jobs such as lawyers and credit research. Conclusion: Therefore, this study analyzes the bills related to the authorized detective to the National Assembly, examines major issues such as the scope of work of the authorized detective business, the selection of management and supervisory authorities, and suggests ways to improve the successful settlement of the Private Investigator system.

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 is to suggest legalization of private investigation system by giving an example of Japanese detective investigation on people who have been missing for a long time. To accomplish the research purpose, this study reviewed literature and used preceding researches on Japanese detective system to complete theoretical background. This study also identified the missing people in Korea and Japan to accomplish the research purpose. Conclusion: In Japan, about 80,000 people are reported to be missing every year. Although most of them are found on that day or within a week, some of them are not found for more than a week. There even a case where the person was missing for more than 3 years. In such case, the Japanese citizens requests detectives to find the missing person instead of depending on the police. When Japanese detectives are paid by their client, they provide the security service requested by the client. Japanese detectives receive about 100,000 yen to 700,000 yen for finding missing person and they find the missing person through investigation on voluntary or involuntary missing person. Such activities of Japanese detectives point out the necessity of introducing private investigation system in Korea. Currently, most missing people are not found in Korea. Introduction of private investigation system will help in finding the missing person, reducing the excessive workload of police, and creating jobs.

Paul Auster's The Locked Room, the third novel of The New York Trilogy, has been examined by many critics in terms of anti-detective fiction or postmodernism. However, this paper focuses upon how the author adopts and utilizes some key elements of the traditional detective novel and its literary tradition. Mystery storytelling is one of Auster's literary strategies and the theme of the double is another. For his novel Auster explores the theme of the double as in Poe's "William Wilson." In The Locked Room, the narrator "I" is described as a shadow of his childhood friend Fanshawe. After Fanshawe's disappearance "I" becomes a literary agent for his friend, and becomes a husband of his friend's wife and a father of his friend's child. Searching for information to write a biography of his friend, he realizes that his friend has always been living inside his skull condemned to a mystical solitude. When Fanshawe appears in the narrator's mind as an image of the door of a locked room, the locked room is also a metaphor for the closed consciousness of the narrator. In his strategy of mystery storytelling, Auster employs the quest of detective fiction as well as the irony of Oedipus the King, where the criminal pursued by the king turns out to be himself. The Locked Room starts with the mystery of Fanshawe's disappearance, and as the novel develops, the narrator pursues numerous clues about his biographical subject like a private eye. Ironically, however, he finds that the ghost of Fanshawe has always been with him and that this is inevitable. As the narrator resolves to quit his life as a double, he contrives to name a strange man Fanshawe as if he tries to turn his biographical subject into a fictional character in the same way Fanshawe has controlled the narrator like a character in Fanshawe's novel. Beaten by the fictional Fanshawe and recovering from a near-death experience, the narrator prepares for his final showdown with Fanshawe. The transcendence of his existence as a double is epitomized by his act to tear off the red notebook handed to him by Fanshawe, which confusingly delivers a message that a life is doomed to be a failure. The narrator's act to cut off Fanshawe's influence bespeaks his breaking out of his locked consciousness and a new start for his life with his own identity.

A scanning slot digital mammography system Luing a plastic scintillating fiber screen (SFS) is currently being developed To improve the x-ray interaction efficiency and absorption efficiency of an SFS, high Z elements can be added into the scintillating fiber core. In this paper, we investigated theoretically the zero spatial frequency detective quantum efficiency, DQE(0), and modulation transfer function, MTF(f), of three 2 cm thick SFSs made of polystyrene, polystyrene loaded with 5% by weight of lead, and polystyrene Loaded with 10% by weight of tin scintillating fibers. X-ray interaction efficiency, scintillating light intensity distributions and line spread functions were generated using Monte Carlo simulation. DQE(0) and MTF(f) were computed for x-ray energies ranging from 15 to 50 keV. Loading high Z elements into the SFS markedly increased the DQE(0). For x-ray energies used for mammovaphy, DQE(0) values of both high Z element loaded SFSs are about a factor of three higher than the DQE(0) of an Min-R screen. At mammographic x-ray energies, MTF(f) values of all three SFSs are Venter than 50% at 25 Ip/mm spatial frequency, and were found to be dominated by the 20 um individual scintillating fiber diameter used The results show that both hiP DQE(0) and spatial resolution can be achieved with the high Z element loaded SFSs, which make these SFSs attractive for use in a scanning slot detector for digital mammography.

Low story apartments and housings with manual fire extinguishers are very susceptible to fro damages, when people are absent or there are old and weak peoples. To reduce such fire damages, automatic fire suppression at the early stage is very important, and thus automatic and cost-effec-tiye fire extinguisher was developed. This study revealed that the reaction temperature and response time are greatly influenced by the small thickness variation of the detective parts and heating rates. The influence of the thickness of the detective parts was shown significant when the heating rate was low, The reduction in the thickness could lower the response time to 40seconds.
