This paper, so far to analyze the research trends in the issue that has been discussed for the introduction of private investigation institutions, by projecting its suggestion, want the investigation purpose of presenting the desirable introduction direction. The analyzed issue was extracted for existing research material on the introduction of private investigation institutions. Investigators pointed out issue is the name, business scope, corporate, qualification system (eligibility criteria and test), education, association establishment, regulatory agencies, has been included in the eight categories such as legislation form. For the name, I think there is a need to unify under the name "detective". For the scope of work, the amendment is difficult law, place an overview of the general business rules, more specific and detailed investigation business content, to discipline through the ordinance it is possible to be rational. Private investigation institutions, I think the need for limited operations of the corporation. For education, the new education and re-education on a regular basis I do for the private investigation workers. You must be one of the National Police Agency to the management authority. Legislative form, not to be defined by its own law, the revision of the security law, but that is to complement the provisions for private sector research system is effective.

The private military company(PMC) or the private military industry may be one of the most important, but little understood developments in security studies to have taken place over the last decade. This new industry, where firms not only supply the goods of warfare, but rather fulfill many of the professional service functions, is not only significant to the defence community, but has wider ramifications for global politics and warfare. The private military industry emerged in the early 1990s. Its underlying cause was the confluence of three momentous dynamics - the end of the Cold War and the vacuum this produced in the market of security, transformations in the nature of warfare, and the normative rise of privatization. In order to introduce MPFs(Military Provider Firms) into Korea, where in principle private citizens are prohibited to own a gun, unlike the United States, a special law should be enacted which allows them to possess weapons and fight in combat. Therefore, the National Assembly of Korea has been submitting and discussing "the Act on the Prevention and Conduction of Practice of Piracy" since 2014.

The main challenge at present in constructing hierarchical identity-based encryption (HIBE) is to solve the trade-off between private-key size and ciphertext size. At least one private-key size or ciphertext size in the existing schemes must rely on the hierarchy depth. In this letter, a new hierarchical computing technique is introduced to HIBE. Unlike others, the proposed scheme, which consists of only two group elements, achieves constant-size private keys. In addition, the ciphertext consists of just three group elements, regardless of the hierarchy depth. To the best of our knowledge, it is the first efficient scheme where both ciphertexts and private keys achieve O(1)-size, which is the best trade-off between private-key size and ciphertext size at present. We also give the security proof in the selective-identity model.

This thesis analyzes the effectiveness of master's transformational and transactional leadership on organizational commitment as well as job satisfaction of private security, scrutinizes the difference in master's leadership according to social-demographic group. The sum of this thesis is as follows. To begin with, analyzed the difference of leadership style according to social-demographic characteristics of private security, it showed that monthly income is over 2.5 million won as well as people over 30 years old have higher transformational leadership than the others. That is, the older people's age is and the more someone gains his living, the higher he esteems and trusts his master who has charisma, personal concern and shows intellectual stimulus. And examined thoroughly the difference of organizational commitment as well as job satisfaction in accordance with social-demographic characteristics of private security, people who are 20-25 years old, are college graduates and employees who have worked for 2-3 years do well calculational commitment. It means that the younger he is and the lower academic background is, the higher calculational commitment is by the profit and loss which affects them. Secondly, inquired into consequence of leadership style on job satisfaction. Leadership of intellectual stimulus has negative effect on job satisfaction, whereas it has positive effect on conditional compensation. Exactly, if the master exhibits leadership that stimulate to improve an initiative, it reduces the job satisfaction. On the contrary, for the reason that his master indicates leadership that accompanies conditional compensation, job satisfaction tends to increase. Finally, judged from the effects of leadership style on organizational commitment, the charisma, the lower factor of transformational leadership affects to emotional commitment positively and then, it shows that employees tend to become attached to the organization and have a sense of oneness with it, if their master is able to show charismatic leadership. In conclusion, the private security companies pursue employees whose school career and payment is lower because of incidence in labor expense related with the profit and loss. Owing to it, employees are not satisfied with their job much. And also there is the change in increasing rate of job satisfaction according to business performance of the conditional compensation, i.e. a consideration, a promotion, etc., and the calculational commitment. Therefore, the university should try to focus on the researches for cultivate more professional manpower for business, the companies must try to make better deal, offer welfare for their employees to develop of the private security industry, to rise the job satisfaction of private security. And then, investigation to find private security's own level ought to be done by organic industry-academic cooperation of university and industries.

IDS/IPS and networked computer systems are playing an increasingly important role in our society. They have been the targets of a malicious attacks that actually turn into intrusions. That is why computer security has become an important concern for network administrators. Recently, various Detection/Prevention System schemes have been proposed based on various technologies. However, the techniques, which have been applied in many systems is useful for existing intrusion patterns on standard-only systems. Therefore, probe detection of private clouds using BlockChain has become a major security protection technology to detection potential attacks. In addition, BlockChain and Probe detection need to take into account the relationship between the various factors. We should develop a new probe detection technology that uses BlockChain to fine new pattern detection probes in cloud service security in the end. In this paper, we propose a probe detection using Fuzzy Cognitive Map(FCM) and Self Adaptive Module(SAM) based on service security using BlockChain technology.
