시아노아크릴레이트 훈증법은 비다공성 표면에 유류된 잠재지문을 현출할 때 효과적이다. 본 연구는, 진공챔버에서 시아노아크릴레이트를 훈증할 때 온도, 습도, 훈증 방법 등이 잠재지문 현출에 미치는 영향을 확인한 후 최적 반응 조건을 찾는데 있다. 진공챔버의 온도가 높을수록 시아노아크릴레이트 증발량은 증가했지만, 지문 융선에서 시아노아크릴레이트의 중합반응은 $30^{\circ}C$에서 가장 잘 일어났다. 상대습도가 40%, 50% 조건에서는 좋은 상태의 지문이 현출되었지만, 30%보다 낮거나 60%보다 높은 조건에서는 지문 융선에서 시아노아크릴레이트 중합반응 속도가 느려졌다. 진공챔버에서 시아노아크릴레이트를 자연적으로 증발시키는 방법보다는 $OMEGA-PRINT^{TM}$ dispersal pads와 수산화나트륨을 포함한 솜을 이용해 시아노아크릴레이트 훈증하는 방법이 효과적이란 사실을 확인할 수 있었다. 진공챔버에서 시아노아크릴레이트 처리시간은 상대습도에 비해 큰 영향을 주지 않았다.

민간조사제도는 사회문제로 등장하고 있는 심부름센터, 흥신소 등의 기능을 대체하고 경찰 기관 등 형사사법 기능을 보완하여 국민의 법률서비스의 길을 향상시킬 수 있다는 점에서 긍정적인 측면도 있지만 민간조사관들의 실질적인 활동과정에서 시민의 사생활 침해의 가능성을 지닌 것도 간과할 수 없기 때문에 신중한 접근이 필요하다고 볼 수 있다. 민간 경비의 한 분야에 속하는 민간 조사는 선진국에서는 경찰 및 민간 경비의 성장과 함께 발전해 왔으며 우리나라를 제외한 OECD 가입국에서는 민관조사와 관련된 법규를 제정하여 민간조사 제도를 발전시켜 왔다. 우리나라에서는 민간조사법 제정을 위한 여러번의 노력이 있었지만 여러사정으로 민간조사제도가 시행되지 못했다. 2008년 9월에 제출된 이인기 의원의 경비업법 개정안은 국민들이 사실관계 조사가 필요하더라도 전문성과 시간적 제약으로 본인들이 할 수 없기 때문에 국가에서 전문자격을 취득한 민간조사관에게 사실 조사서비스를 맡겨 서 사생활 침해도 방지하고 영업의 적정성도 도모하고 민간조사업을 건전하게 육성하기 위한 것이라고 볼 수 있다. 본 연구는 국회에 제출된 경비업법 개정안을 중심으로 문제점을 분석해보고 바람직한 경비업법의 방향을 제시하는데 연구의 목적을 두고자 한다. 본 법안의 문제점과 각계의 의견을 수렴하고 보완하여 국내 실정에 맞는 민간조사제도가 도입되길 희망하면서 민간조사제도의 성공적 정착을 위해서는 국민, 학계, 관련기관의 공동의 관심과 노력이 필요하다고 본다.

As a traditional method to apply fingerprint powder, brush method ("dusting") can create a risk to the health of crime scene investigators due to the inhalation toxicity of harmful and fine powders. Therefore, as a new method of applying powders, we tried to evaluate the potential of a chamber method for the development of latent fingerprint using fans in a closed chamber with a fixed capacity that can prevent the powders from being blown outside and exposed to the users, by comparing with the development results of the conventional brush method. Fingerprints on glass and plastic (PET) were extracted with black powder and green fluorescent powder, and the sharpness and minutiae of the developed fingerprints were compared for each method. The results of the black powder showed similar results, but the effect of the chamber method was slightly decreased when the green fluorescent powder was used. In order to improve the development with the green fluorescent powder, the mixture (50 : 50) of the fluorescent powder with the silica gel was tested and the results were similar to those of the brush method. It is expected that the chamber method has a high potential as a new powder application method considering the health of the crime scene investigator after fine tuning of development conditions with additional studies.

The characteristics of the records management systems of the Japanese colonial government can be summarized as follows. First, the Government General adopted a "decentralized retention" of public records. The Government General did not establish its own archives for central preservation of permanent public records. Colonial agencies established its own records office and the records office managed the records its agency created. Secret records and police records were exception. They were retained by the Secretary Office of the General Affairs Division and Police Division of the Chosun Government General respectively. Second, filing systems and retention periods of the public records followed the hierarchic structure of organization. In the headquarter of the government, records were filed by a "bureau-division-activity-file" classification system and a retention period of a file was given automatically by each unit the file belonged. A closed and cut-off file was retained and arranged according to its creating unit, creating year, and retention period. The filing system was easy to use once the filing system was established well, but to make it work effectively changes in activities and organizations should be on a reflected regular basis. It had an advantageous effect that permanent records could be preserved in a unified way throughout the organization. However, it is very critical to determine the permanent records in a professional way. Selection of the permanent records should be done professionally and in a historical perspective. Otherwise, the records retained as permanent records were not the records having an enduring value. And that was not done by the colonial government. Third, classification and scheduling of records were carried out by a creating division, rather than by the Records Office, mostly from the 1920s. Compilation of the records was also done by the creating agency. It implies that the records management lacked the professionalism. In conclusion, the records management system of the Chosun Government General wes nither modern nor user oriented. It managed the records for solely administrative purpose, i.e. effective colonial rule. The legacy of the colonial records system still exists in the public records system in Korean government. One should criticize the lack of will and efforts to modernize the public records system since the establishment of the Korean government while should reflect the historical origins of the records system in Korea.

Since the unprecedented hydrogen fluoride leak accident in 2012, there has been growing demand for customized technical information for rapid response and chemical accident management agencies including the Ministry of Environment, the National Emergency Management Agency, and the National Police Agency need more information on chemicals and accident management. In this regard, this study aims to provide reliable technical data and guidelines to initial response agencies, similar to accident management technical reports of the US and Canada. In this study, we conducted a questionnaire survey and interviews on initial response agencies like fire stations, police stations, and local governments to identify new information items for appropriate initial response and improvements of current guidelines. We also collected and reviewed the Canada's TIPS, US EPA's hydrogen fluoride documents, domestic and foreign literature on applicability tests of control chemicals, and interview data, and then produced items to be listed in the technical guidelines. In addition, to establish database of on-site technical information, we carried out applicability tests for accident control data including ① emergency shut down devide, safety guard, shut down valve, ground connection, dyke, transfer pipe, scrubber, and sensor; ② literature and field survey on distribution type and transportation/storage characteristics (container identification, valve, ground connection, etc.); ③ classification and identification of storage/transportation facilities and emergency management methodslike leak prevention, chemicals control, and cutoff or bypass of rain drainage; ④ domestic/foreign analysis methods and environmental standards including portable detection methods, test standards, and exposure limits; and ⑤ comparison/evaluation of neutralization efficiency of control chemicals on toxic substances.

This paper is concerned with simulation exercises used to train key response agencies for crisis situations. While 'multi-agency' simulations are increasingly acknowledged as a necessary and significant training tool for emergency response organisations, many current crisis simulations are still focused on the revision of existing response plans only. However, a crisis requires a rapid reaction, yet in contrast to an 'emergency', the risks for critical decision makers in crisis situations are difficult to measure, owing to their ill-structure. In other words, a crisis situation is likely to create great uncertainty, unfamiliarity and complexity, and consequently should be managed by adaptive or second order expertise and techniques, rather than routine or structured responses. In this context, the paper attempts to prove that the current practices of simulation exercises might not be good enough for uncertain, unfamiliar, and complex 'crisis' situations, in particular, by conducting case studies of two different underground fire crises in Korea (Daegu Subway Fire 2003) and the UK (King's Cross Fire 1987). Finally, it is suggested that the three abilities: 'flexibility', 'improvisation' and 'creativity' are critical in responding to a crisis situation.

Online cybercrime has various causes. The criminal guilty language, Criminal lingo is active in the shaded area with the bilateral aspect of the word on cyber. It has been continuously producing massive risk factors in cyberspace. Criminals are shared and disseminated online. It has been linked with fake news and aids to suicide that has recently become an issue. Thus the criminal lingo has become a real danger factor on cyber interface. Recently, Criminal lingo is shared and distributed as cyber hazard information. It is transformed that damaging to the youth and ordinary people through the internet and social networks. In order to take action, it is necessary to construct an expert system based on AI to implement a smart management architecture with block-chain technology. In this paper, we study technically a new smart management architecture which uses artificial intelligence based decision algorithm and block-chain tracking technology to prevent the spread of criminal lingo factors in the evolving cyber world. In addition, through the off-line regular patrol program of police units, we proposed the conversion of online regular patrol program for "cyber harem area".

Fingerprinting is a frontier technique that is the most frequently applied for human identification throughout the world. All citizens over 17 year old living in the Republic of Korea must be fingerprinted to obtain a certificate of resident registration. In Korea, for this reason, human identification through fingerprints has been far better developed and used efficiently both in crime scene investigation and in confirmation of an unidentified body. Scientific approaches have been made to accurately extract the metamorphosed fingerprints in various environments. Because most of the studies on fingerprinting have been accomplished with biometric techniques, researches on restoration of human dermal tissue and taking custody data after collecting fingerprints have been comparatively undermined. In this study, a newly innovative method for fingerprint extraction was developed using the polyester film with print powders and the high temperature-moisturizing method. Compared to the conventional fingerprinting method of paper with ink, minutiae numbers of fingerprints were greatly increased in polyester film with print powders after restoration of fingertips by high temperature-moisturization. This newly developed procedure would be an efficient fingerprinting technique which could be utilized in scientific investigation and in personal identification in the future. Furthermore, the new method for restoration and extraction of fingerprints are easy and inexpensive to practice for a number of human identification.

A fingerprint is an impression of the friction ridges of all or any part of the finger. A friction ridge is a raised portion of the epidermis on the palmar (palm and fingers) or plantar (sole and toes) skin, consisting of one or more connected ridge units of friction ridge skin. There are two fundamental principles underlying the use of fingerprints as a means of identifying individuals - immutability and uniqueness. Friction ridges develop on the fetus in their definitive form before birth. Ridges are persistent throughout life except for permanent scarring. Ridge patterns and the details in small areas of friction ridges are unique and never repeated. Friction ridge patterns vary within limits, which allow for classification. We developed the high temperature-moisturizing method to obtained quality postmortem impressions from decomposing friction ridge skin. This technique is a simple procedure that uses boiling water to recondition the skin. This reconditioning process enhances detail present on the fingers and exposes ridge detail not visible to the naked eye. Therefore, we can recover the quality fingerprints, even from the worst decomposed bodies.
