A Study on the Countermeasures against International Computer Crime focusing on the Police Investigation Procedure. These days, much more intelligent, varied and advanced techniques for computer crimes have been used than for development of technology. In particular, it has been reported that the damages are enormous. Damages of some computer crimes can not be accurately reported. This study is to speculate specific types of computer crimes and obtain its prevention and countermeasures centering on the Police Investigation Procedure. In particular, it is to speculate international cooperation under the condition that global damages occur frequently due to preparation of advanced network environment.

Social network services(SNS) has been used as a means of communication for user or express themselves user. Therefore, SNS has a variety of information. This information is useful to help the investigation can be used as evidence. In this paper, A study of mobile digital forensic procedure for crime investigation in social network service. Analysis of database file taken from the smartphone at social network service application for mobile digital forensic procedure. Therefore, we propose a procedure for the efficient investigation of social network service mobile digital forensic.

It requires professional knowledge and much time to judge intellectual property rights infringement. The duties of customs administration are the balance between the propositon of trade facilitation through rapid clearance and the thesis of social security through exact examination. There is a view that the criminal procedure law control is necessary to the goods inspection of clearnce procedure if it is related to crimianl investigation. However, it seems that the customs law does not consider the goods inspection investigation as the investigation under judicial control, but only the mere administrative investigation. It can be said that the inspection of goods by customs law functioning as a clue of investigation is confined to the ordinary goods inspection, including the screening test. Searching for specific articles by specific informaition should be under the control of criminal procedure law because it constitutes the commencement of criminal investigation in criminal cases. This interpretation could be an opportunity as a harmonious operation between the goods inspection of customs clearance and the search and seizure of criminal procedure.

When assessing buildings that may collapse during a large earthquake, conventional rapid visual screening procedures generally provide good results when identifying buildings for further investigation. Unfortunately, their accuracy at identify buildings at risk is not so good. In addition, there appears to be little room for improvement. This paper investigates an alternative screening procedure based on fuzzy logic and artificial neural networks. Two databases of buildings damaged during the Athens earthquake of 1999 are used for training purposes. Extremely good results are obtained from one database and not so good results are obtained from the second database. This finding illustrates the importance of specifically collecting data tailored to the requirements of the fuzzy logic based rapid visual screening procedure. In general, results demonstrate that the trained fuzzy logic based rapid visual screening procedure represents a marked improvement when identifying buildings at risk. In particular, when smaller percentages of the buildings with high damage scores are extracted for further investigation, the proposed fuzzy screening procedure becomes more efficient. This paper shows that the proposed procedure has a significant optimisation potential, is worth pursuing and, to this end, a strategy that outlines the future development of the fuzzy logic based rapid visual screening procedure is proposed.

In an effort to enhance the independence of and expertise in military aircraft accident investigation, a permanent accident investigation board should be established. Establishing permanent accident investigation board would render the military accident investigation more reliable and would increase its public esteem. Because there is no provision governing the responsibilities of the investigation and cooperation between civil and military authority in case that both civil and military aircraft are involved, it is necessary to fill this gap by enacting appropriate laws. In case of civil aircraft accident investigation involving a military issue, it would be better to allow military authority to be involved in the investigation. For the betterment of investigation, it is also necessary to provide a field investigator an authority to directly collect relevant information. Since the sole purpose of accident investigation is to prevent the recurrence of aircraft accidents, the scope of information disclosure should be limited and the investigation report shall be used for neither criminal procedure nor disciplinary procedure so that the objectivity of the investigation should be ensured.

The objective of this study was to establish a procedure of concurrent engineering which can be easily a, pp.icable in Korean industry. An investigation of various techniques of concurrent engineering was conducted. Problems of Korean companies which can be resolved by concurrent engineering techniques were identified. Techniques which can resolve these problems at the relatively low cost and without complicated computer facilities were selected and form a procedure for this study. The procedure was a, pp.ied to a manufacturing company for validation. It was found that this procedure can substantially reduce time and cost of R&D and manufacturing.

Cloud computing is a service that to use IT resources (software, storage, server, network) through various equipment in an Internet-enabled environment. Due to convenience, efficiency, and cost reduction, the utilization rate has increased recently. However, Cloud providers have become targets for attack Also, Abuse of cloud service is considered as the top security threat. The existing digital forensic procedures are suitable for investigations on individual terminals. In this paper, we propose a new investigation model by analyzing the vulnerable points that occur when you investigate the cloud environment with the existing digital forensic investigation procedure. The proposed investigation model adds a way to obtain account information, and can apply public cloud and private cloud together. Cloud services are also easily accessible and are likely to destroy digital evidence. Therefore, the investigation model was reinforced by adding an account access blocking step.

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.

This paper suggests a PDA-based scientific traffic accident investigation system in order to improve the reliability and accuracy of a traffic accident investigation procedure. In order to fulfill this objective, a standard accident sheet with 32 elements to be used in the PDA system was developed through a reference review and an expert survey. Using this information, the required functionalities and realization procedure of the PDA system for traffic accident investigation were presented including mobile network environment and GPS/GIS design. A prototype of PDA system is presented and more improved and efficientmanagement is highly expected by applying the system developed in this paper.
