MySQL database is the second place in the market share of the current database. Especially InnoDB storage engine has been used in the default storage engine from the version of MySQL5.5. And many companies are using the MySQL database with InnoDB storage engine. Study on the structural features and the log of the InnoDB storage engine in the field of digital forensics has been steadily underway, but for how to restore on a record-by-record basis for the deleted data, has not been studied. In the process of digital forensic investigation, database administrators damaged evidence for the purpose of destruction of evidence. For this reason, it is important in the process of forensic investigation to recover deleted record in database. In this paper, We proposed the method of recovering deleted data on a record-by-record in database by analyzing the structure of MySQL InnoDB storage engine. And we prove this method by tools. This method can be prevented by database anti forensic, and used to recover deleted data when incident which is related with MySQL InnoDB database is occurred.

Private security industry in South Korea has rapidly been growing in recent years. However, such a rapid growth is being criticized for its focus on external results, which has produced a number of problems. The continued growth of private security industry can be only based upon substantive and qualitative development. In this aspect, it is necessary to consider the global trends of the private security industry, particularly the recent trends of the U. S. security industry which has led the global security industry. This is because the recent trends of the U. S. private security industry would guide the future direction of the private security industry in South Korea. The U. S. private security industry has been replacing the role of law enforcement agencies including the police, from crime prevention to investigation and disaster management, not to mention asset protection and loss prevention. The recent trends of the U. S. security industry appears to be summarized by such characteristics as variety, specialty, and integration, which might account for the structural problem of the private security industry in South Korea. In short, the substantive and qualitative development of the private security industry in South Korea should be accomplished by strengthening its specialty and integration, and also widening its variety.

In the mordern society, the reliance on the cyber domain and the cyber connectivity has been increasingly strengthened. Due to this phenomenon, the cyberterror against critical infrastructures and state organs might lead to fatal consequences. Lately, North Korea's cyberattacks against South Korea's national organizations and financial computer networks are becoming more and more intelligent and sophisticated. The cyberattacks against such critical infrastructures have caused enormous economic loss and social disorder. This paper is designed to examine comparatively the cyberterror related laws and organizations of the advanced countries such as U.S. and U.K. and to draw implications. Although those countries are under different institutional and cultural backgrounds with varying security envrionments, they are identically pursuing measures by establishing government-wide counterterror system for coordination and cooperation. They are also commonly focusing upon creating new organizations equipped with new system and upon enhancing intelligence performance and devising punishment regulations. Korea is lack of framework laws regulating cyber security, having only scattered individual laws. Since such legal base is far from efficient counterterror activities, it is necessary that the legal and policy response of the advanced countries should be closely studied for selective introduction. That will eventually lead to legislation of cyber security law. With such legislation on hand, it is subsequently required to strengthen crisis management for prevention of cyberterror and to create joint response team, cooperating with private organizations.

This study examined how the meaning of news stories covering the split of national opinion was constructed in the media to represent social conflicts. To clarify the function of the term 'split of national opinion' as an ultimate term, this study examined the meaning of the term in the context of both text and society. Ten newspapers were included in the content analysis. The frequency of words used for the purpose of metaphor and equivalent in describing the split of national opinion was calculated to determine their meaning in the textual context. The frequency of incidents and subjects involved in allegedly causing the split of national opinion was calculated to determine their meaning in the social context. The results of this study are summarized as follows: First, the term 'split of national opinion' was coined by the newspapers as a metaphor of disease, disaster, and cost. The attitudes or the ways in which the split of national opinion was dealt with were generally negative and passive. Second, the term 'split of national opinion' was dealt with an equivalent status of such terms as national policy, national loss, societal problems, and ideology. Third, each newspaper reported that the split of national opinion had been caused by certain subjects, which indicates that each newspaper had its own position of viewing who was the key player in splitting the national opinion. The implication was also discussed that the use of the ultimate term would incur the unbalance of power between participants and the existing players, which would make individuals or groups who were involved in the social actions excluded and make the newspapers exercise the rhetorical power as news media.

The guarantee of citizens' safety from crime is the reason for a nation's existence according to the social contract, and it is also a salient task in securing the citizens' right to the pursuit of happiness, which is a constitutional right expressing the nation's duty to its citizens. First, a procedure must be made mandatory that corresponds to the Miranda rule applied during the arrest of criminal suspect, which verifies whether there exists a risk of retaliatory crime to the victim of crime, crime reporter, or witness following their report of a crime or testimony. A measure to punish those who violate this should be devised. The second is the improvement of related laws and systems, such as expanding the scope of persons subject to protection from retaliatory crimes under the current law and strengthening information protection. Third, a retaliatory crime risk evaluation index must be developed, and the evaluation results must be quantified to clearly state measures and responsibilities, in detail, for personal safety at each level of intensity. The fourth is the expanded implementation of proactive personal safety measures for victims of crime and witnesses, as well as the development and application of advanced techniques. The last is a change in the perception s of those working for the judicial body. From the initial investigation stage of the crime to the diagnosis regarding the possibility of retaliation perpetrated on an ex-convict through psychological tests, systems of general cooperation, and mutual assistance must be established.

Medical certificate is a document to demonstrate a patient's health status, made up and signed by a physician, dentist, or oriental physician who attended the patient. It serves as an evidence in many official process including civil or criminal law suit, especially for one's personal injury. The Korean legal system also acknowledges and protects the evidentiary function of medical certificate by mandating physicians etc. to issue medical certificate in good faith and only when they personally attended the patient, and by criminally punishing them when they do not comply with these legal requirements. There are some reasons, however, that medical certificates often do not reflect the true health status of the patient: When physicians attend the patient and collect information regarding the health status of the patient, their priority is and should be the most cost-effective way to meet the health needs of the patient. It does not necessarily correspond to the accurate examination of the health status of the patient. Even when the patient's report on the history of the illness or the injury seems suspicious, physicians might have to avoid disproving it because that kind of attitude might harm the rapport between the physician and the patient. All these can distort the perception of the physicians and this distortion can be reproduced in the medical certificate they made up. Some of these problems might be resolved or at least enhanced by introducing new form of medical certificate which would guide physicians to reveal the nature, factual and theoretical grounds, and the limit of their findings more accurately. Others, however, would not be able to address, because it stems from the conflict between the physician's primary duty, duty to be loyal to the patient's life and health, and his secondary duty to serve as a public or neutral witness on the health status of the patient, and when both values or duties conflict with each other, they should choose the duty to the patient sacrificing the duty to the public or the court.

For the quality improvement on private security industry, the quality of personnel in private security should be advanced through the systematic training. If the personnel in private security provide an advanced service in applying knowledge and technique to the field when in training, they can obtain the reliability from people. With the point of this side, practical and systematic training is essential to the restoration on the private security industry. The personnel of private security face many people in the field. So they must work with an active concept that can prevent additional crime from behavior suspicions through scientific observation method and systematic inquiry method rather than negative work with providing a friendly service in the field. For conducting this concept, therefore, this study suggested the improvement training program of "Question and Research Guides" from new employee training on existing private security. The scientific observation standard is specifically suggested from the study 'people watching' of Professor Morris, D. and an act contact question from lead technique that US FBI, police, and inspection institute are taking through the feature of human act and 'METT' that is the program for emotion capture training through human minute look is going to be applied on "Question and Research Guides" training. This will provide the educational mood for students with the training content that is available for the practical training program and the real work, and will help to restore the private security industry with obtaining people's reliability through the scientific work and advanced field treatment.

The purpose of this paper is to introduce the industrial security policies in Germany and to look for the implication for the development of korean industrial security. Due to highly developed economy and industrial technology, Germany has become the main stage for the industrial espionage for a long time. In Germany industrial espionage is classified into two categories; Economy-espionage and Competition-espionage. While economy-espionage is related to the Espionage of foreign intelligence agencies, Competition-espionage means the act of espionage, that is implemented by the private sector. When it comes to economy-espionage, prevention of economy-espionage is the duty of the State, because it threat the national interest. Otherwise, the private sector has to take the responsibility of prevention of competition-espionage. It goes without saying that, the state has to investigate the crime, when espionage happens. But Prevention is more important than investigation in this regard. For the realization of Public-Private-Partnership, the private sector should be the genuine counterpart of the Public through the sharing responsibility of industrial-espionage prevention. Another talking point this paper suggest, is the national ethic in connection with economy-espionage. The State could be not only a actor of espionage prevention, but also a perpetrator. The economy-espionage for the purpose of national interest would not be justified, unless it has nothing to do with national security.
