The purpose of this study is to examine the effect of police investigation environment on perception toward legalization of private investigation. To enhance the completeness, this study conducted a survey on police officers in service and analyzed the survey data through statistical technique. The results for examination on how police investigation environment influence on perception toward legalization of private investigation were as follows. When the 'work burden from long-term cold case' composing the police investigation environment is high, the police officer highly evaluated the growth potential of private investigation, showed positive perception toward private investigation market, and showed intention for re-employment at private investigation agency after retirement. When the police officer experiences more difficulties from 'investigation other than criminal case', the police officer highly evaluated the growth potential of private investigation and showed intention for re-employment at private investigation agency. In addition, when the police officer thinks that there are a lot of difficulties for "Limited investigation on specialized area", the police officer showed positive perception toward growth potential of private investigation and private investigation market. In addition, police investigation environment showed significant result on legalization of private investigation. The result also verifies that as the difficulty of crime investigated by the police is getting higher quantitatively and qualitatively, it is necessary to introduce private investigation system which is specialized and able to investigate for a long time. This study hopes that this study result would be utilized as the grounds in signing the bill for introducing the private investigation system.
The object of this study is to propose a study on the Private Investigator usage for Cyber Crime. The latest trend of cyber crime is being evolve in sophisticated and complex way over the global, like internet fraud, cyber gambling, hacking and etc. Hence national investigative authority mobilize high specialized skills and method of criminal investigation by each nation. But it is hard to respond in rapid and effective way because of propoor, distribution of group and insufficient of related legal system. Already in other countries, not considerable amount of services are given to private investigators in detection and tracking part which is inefficient by nation. So it has significantly meaningful to compensate the defect and study about private investigator usage as companion of cooperation policing for effectively respond to cyber-crime. The way to effectively deal with the cyber-crime is reevaluate meaning of partnership policing and need of private investigator usage. Also it is to analyze the main issue about introduction of a system and suggest the effective way of introduction. First, legislation of private investigator usage which is based upon partnership policing should be made up. Moreover, to establish the range of private investigator's business and enhance the reliability, it is to propose introduction of leading professional global certificate and license system with sufficient education and test. We are expecting introduction of private investigator usage can improve efficiency of investigation and promote effective countermeasures of cyber-crime.
In terms of resources recycling and resolving waste disposal problems, it is very important to recover precious metals like Au, Ag and Pd and valuable metals like Cu, Sn and Ni from the scraps of waste electrical and electronic equipment(WEEE) that consists of detective electrical and electronic parts discarded during manufacturing electrical and electronic equipments and waste electrical and electronic parts generated during disassembling them. In general, the scraps of WEEE are composed of various metals and alloys as well as refractory oxides and plastic components. Precious and valuable metals from the scraps of WEEE can be recovered by gas-phase-volatilization, hydrometallurgical, or pyrometallurgical processes. However, the gas-phase-volatilization and hydrometallurgical processes have been suggested but not yet commercialized. At the present time, most of the commercial plants for recovering precious and valuable metals from the scraps of WEEE adopt pyrometallurgical processes. Therefore, in this paper, the technical and environmental aspects on the important pyrometallurgical processes through literature survey are reviewed, and the scale-up result of a new pyrometallurgical process for recovering the precious and valuable metals contained in the scraps of WEEE using waste copper slag is presented.
This study aims to analysis and measure on the private security for the academic directivity and security industry for the market directivity in Korea. For this study we compare and analysis the curriculum of 15 universities in Korea and the papers which were published on "Korean Security Science Review" that is a report in a professional private security. In conclusion, 269 subjects are used as instructional materials in 15 universities, thus 103 subjects for the private security and 60 for the leisure sports and first-aid treatment, 46 for the social science, 30 for the martial arts and shooting, 16 for the secretary affairs, 14 for the foreign languages. Regarding scientistic papers, 45.7% of papers for the private security of all and 14.6% for the public security, 14.6% for the criminal, and 11.6% for the terror etc. But there are any papers for the facilities guard or security in spite of the facilities guard is pivotal role in this field. The facilities guard or security, or maybe house detective, holds 80.5% of the private security market and it is important role in this industry in Korea. Besides, considering development of private security, the security market makeup the body-guard field hold 12.2%, prevention security system by censor hold 4.1%. So, this statistics show that the facilities guard lead practically the private security industry in this field, but there are any subjects for the education and any research for the paper. Thus some modification on the universities curriculum is required, also needs activity research in the facilities guard field for the development private security.
To investigate the condition of infectious rate of fascioliasis in the farm animals. This survey was carried out, by the interdermal reaction from different animals, ages and pestures in Daejeon Suburbs and Cattle market and Abattoir. The average positive rate of infectious reaction were 31.0% in Korean Cattle, 38,7% in dairy Cattle, 33.8% in Korea native Goats and 26.9% in dairy Goat. The positive rate was higher at the age of 2~6 that compares with at age of yearling. From survey on the river side area, valley and wet area, the rate of positive was occured higher, than from plain, high land and in case of animals have not been grazing. And the detective rate of liver fluke among the positive reaction was occured 92.5% in Korean Cattle and 94.7% in Korea native Goat.

Landsat is one of the popular satellites for observing land surface that is used in various areas including monitoring, detecting and classifying changes in land surface. However, shades, which cloud itself and its shadow, interrupted often clear observation and analysis of ground surface. For this reason, the process of removing shades and restoring original ground surfaces are critical for geospatial users. This study is planned to recommend a methodology for more accurate and clear images of Landsat-8 sensor, which provided two additional bands of costal/aerosol and cirrus. In fact, those bands are known as functioned effectively in detecting and restoring shades. Otsu's thresholding technique to detect clouds, we replaced those detective shades by using experimental and reference images. In accurate assessment, the overall accuracy and kappa coefficients were about 85% and 0.7128, respectively. This indicates that the proposed technique is effective for recovering the original land surface.

Purpose: Purpura fulminans is a rare but rapidly progressive, serious, often life-threatening disorder in childhood, which is complicated with septic shock or disseminated intravascular coagulopathy during acute infection. It occurs first as acute-onset petechial rash, and spreads rapidly into full thickness skin and soft tissue necrosis. In the past, it had high mortality rate, up to 80%, but recently, survival rate has increased due to early diagnosis, and rapid advancement of critical care and antibiotics. From our experiences of PF management, we would like to review the pathophysiology and suggest the surgical treatment guideline about meningococcal induced purpura fulminans. Methods: Two cases of purpura fulminans over the last 3 years were reviewed retrospectively about reconstructive management. After they were treated resuscitative management initially by the critical intensive care, reconstructive surgery was performed by plastic surgeon as soon as the patients were vitally and mentally stable. Results: There were 6 procedures in case 1, and 3 procedures in case 2. The mean delayed period from admission with sepsis to the first surgical debridement was 24 days and 42 days, respectively. Total hospitalization period was 103 days and 69 days, respectively. All of them were treated with debridement and split thickness skin graft, but delayed debridement was superior to early one in the point of preserving much more tissues. Conclusion: From our experience, we suggest that conservative therapy to the wounds appears to be the best tool in the initial vitally unstable period in order to preserve as much tissues and functions as possible if no active inflammation and compartment syndrome are detective.
This study set out to analyze the perceptions of investigative police officers and division police officers regarding Police Investigation Specialization, which had been in effect for four years, identify the problems, and search for alternative policies. The results led to the following alternative policies; first, the communication among the members should be facilitated by trading the jobs between investigative policemen and division members in certain percentage regularly, integrating job education and special work, and developing diverse support programs for detective activities to provide them with opportunities to experience and understand investigation. The second suggestion concerns the investigation members' morale. There should be a range of measures to boost their moral such as allocating separate budget and personnel to support the investigation department and the treatment of major criminal and civil cases, giving each investigation team an office and investigation room to improve their working environment, readjusting the promotion ratio of Police Investigation Specialization to introduce a promotion system proper for each investigation's characteristics. The third suggestion is to secure job efficiency. It's required to reinforce the current short-term specialized education program to bring up practical and professional investigators, open the certification exam of professional investigators to all members so that every policeman can have their abilities recognized and approved as long as they have the demanded capabilities, and create a system of shedding off the members idle at work by reflecting low performance records when evaluating the members to decide who to dismiss from Police Investigation Specialization. And finally, it's important to divide duties rationally. The rationality of duties division can be guaranteed by setting the guidelines for direct handling for the team leader to help him devote himself to his duties, defining objective criteria of measuring investigation workload, and creating devoted systems and teams for simple and small accidents so that experienced investigators can deal with high-profile cases.

This study analysed the effectiveness of aluminium(Al) filter in the added compound filtration for the removal of characteristic radiation from high atomic number material by DQE and image evaluation. 1mm Al was applied to each 0.1, 0.2, 0.3 mm copper and befere and after use were evaluated. Beam quality and DQE were tested by IEC regulations and image quality was evaluated by PSNR, MAE, MSE, CNR, SNR and qualitative analysis was performed by 7 items for resolution and contrast from chest x-ray criteria of national cancer checkup. MTF 10 and 50% were the same by 4.6, 2.54 cycle/mm and NPS, DQE, PSNR MAE, MSE, CNR, SNR and qualitative analysis were all the same or slightly better when Al was not used. PSNR is over 30dB and all significant and at the qualitative analysis, the p-value of t-test was over 0.05. The DQE and image quality evaluation have little difference between before and after use of Al filter and it is effective to use the Al filter for the reduction of skin dose by removal of characteristic radiation.
This paper is an attempt to examine historical drama which change rapidly in the manner of seeing history. Historical records are treated differently unlike in the field of modern history. Now the distinction between historical facts and fictions becomes no longer important. This change is affected by micro history, new cultural history, or post-modern history. History and narrative become interactive each other. In this respect they are no more historical drama. by Han Areum (director Suh Jae-hyung) represents this new trends. Of course, it doesn't suddenly pop up in 2005. It began in by Lee Yoon-Taek, was reinforced in by Kim Tae-Woong, and bloomed in . I intended to search important features of by following three. First is the interest about unimportant persons such as a maid of honor, an eunuch. In , they are the main characters. The author described much about those trivial people revealing the truth in different way of the existence. Second is the way of calling a past. In this piece, the past is not continuous. The past always appears at the stage by the present in the form of split which is imagination, recollection, revival. Third is a mixing genre. Comics, melodrama, and thrillers are all together in . This is a similar phenomenon to historical novel and movie of new trend. Strictly speaking, this piece isn't a history thriller. The accident of lost prince doesn't be treated importantly and the result isn't clear either. In this piece, detective genre is used for a symbol showing that writer pursuits the history, not the event. This represents well the characters of new historical drama because how historical facts are carefully recreated and constructed are important. It's enough to show the possibility to mix genre through comics and melodrama.
