Allowing only authorized users to record and inquire in the ledger, private blockchain technology is attracting attention from institutions and companies. Based on distributed ledger technology, records are immutable. Because news via the Internet can be easily modified, the possibility of manipulation is high. Some false communication report systems are designed to prevent such harm. However, during the gap between the false communication report and verification time, contents on the website can be modified, or false evidence can be submitted intentionally. We propose a system that collects evidence using a headless browser for more accurate false communication management, and securely preserves evidence through a private blockchain and prevents possibilities of manipulation. The proposed system downloads original HTML, captures the website as an image, stores it in a transaction along with the report, and stores it in a private blockchain to ensure the integrity from acquisition to preservation of evidence.

A study on the global trend of accreditation for mediators implies many important aspects of controlling of the quality of mediation. Firstly, whether or not having an accreditation system, most European countries and the U.S. have a common understanding on the fact that mediators need to be trained to mediate disputes, apart from their own expertise on the subject matters. Secondly, private-led accreditation has been utilized in countries having a Anglo-American law system such as the United Kingdom and the U.S. a while nation-managed one has been operated in the countries having a continental law system such as Austria, Belgium, Italy and Germany. Thirdly, private mediation service providers (usually institutions or companies) play an active role in the training and accreditation of mediators and further make them act as mediators in the disputes referred to them. Fourthly, the countries having a nation-managed accreditation system usually stipulate a certain mediation training and accreditation requirement by law. Fifthly, there is no uniform trend on the minimum hours of training required for accrediting the mediators. Sixthly, mediation training generally focuses on the practical mediation capacity-building, including mediation theory and role-playing, mediation simulations, peer review and supervision. And finally, the mediation theory mainly includes the role of mediator, mediation procedures, mediation communication, negotiation and communication skills, mediation ethics and mediator's code of conduct, etc.

Cloud computing is internet-based computing technology. This is a form for exchanging service focused on the Internet. Because Cost is saved and use is easy there's a tendency that many companies are using. Cloud is in the form of a public cloud and private cloud and hybrid cloud. The service model is SaaS, PaaS, IaaS. Cloud computing use is simple but it has a security vulnerability. In particular, there is a vulnerability in virtualization and centralized information. In order to overcome this new security technology is to be developed. In particular, network security technology and authentication technology should be developed. Another way to overcome security responsibilities must be clearly and policies should be unified.

The implementation of electronic transaction raises some new legal and institutional problem so it is necessary for us to prepare alternatives. As the development of electronic transaction is difficult without smooth settlement of dispute the pursue of smooth settlement of dispute is very important menu. while the most common method relating to the settlement of dispute is litigation. them relating to the litigation, the subject of governing law so jurisdiction and the subject of governing laws should be resolved above all. Further more in addition, the old act prior act was regarded as insufficient in that it lacked rules on international governing law to adjudicate, or international adjudicatory governing law, where as the expectation of the public was that the private international law should function as the basic law of the legal relational encompassing rules on governing law given the increase of It international disputes. for the move the private international law has also attracted more attention from the korean. Therefore, governing law to application concerned about electronic transaction should be prepared and the environment to keep electronic transaction secure and stable be guaranteed. And we should make plans to protect companies and consumers and should make efforts to expand electronic transaction infrastructure .

This article summarizes the structure of China's current social health insurance system and reviews the development status of China's private health insurance (PHI). China's medical security system is mainly composed of two parts: basic medical insurance (BMI) and PHI. Among them, the BMI provides reimbursement of basic medical expenses for the insured persons according to different proportions. PHI is a necessary supplement to the BMI and provides assistance to the insured persons in the event of illness or accident. By having PHI, people can obtain medical protection outside the coverage of BMI. In the development of PHI in China, the total medical cost is high and the insurance market size is large, but the proportion of PHI expenditure is low and the personal burden is high. Through this Chinese case, it will be helpful for mutual development between Korean PHI and national health insurance, for Korean insurance companies to enter the Chinese market, and for removing the medical burden on the people.

The paper examines the influence of ownership type on environmental performance of Chinese listed enterprises. China's environmental problems are attributed to the collusion between enterprises and economy-oriented local governments, which has allowed many companies to skirt environmental regulations. Especially, local state-owned enterprises (SOEs) tend to have worse environmental performance than private firms, under the wing of local governments, with whom they have a closer political connection. According to the report of the Environmental Protection Agency, currently the unacceptably poor environmental performance of local SOEs has severely hampered the realization of green economy in China. After examining the dataset of 15,996 firm-year observations from 2,688 listed firms, this paper found that, in the presence of central government supervision and personnel intervention, listed local SOEs will be forced to improve their environmental performance in accordance with standards set by the central government, which leads to better environmental performance than that of listed private firms (private firms). The result of two-stage regression also supports the conclusion. This shows increased supervision and personnel intervention from the central government can significantly improve the environmental performance of local SOEs. The research in this paper expects to make a contribution to attaining the goal of green economy in China.

Disabilities can emerge due to traumatic spinal fractures. In terms of sacrococcygeal spine, because of its unique anatomic structure with minimal movement, the possibility for it to have a disability is relatively low. In Korea, unlike most disability criteria, private insurance companies acknowledge angular deformities caused by vertebral fractures as disabilities according to their degree, so there were several cases where patients required compensation, arguing angular deformity caused by sacrococcygeal fracture, which in some cases led to legal conflicts. Except the Act Welfare of Persons with Disabilities which recognizes only severe angular deformity affecting internal organs as disability and the industrial accident disability evaluation which does not recognize coccygeal fracture as disability but rarely recognizes sacral vertebra deformity equivalent to compressive deformation, there is little or no case where angular deformity is recognized as disability. Given the impairment evaluation standards in social insurance, McBride system, American Medical Association (AMA) guides, and newly proposed standards by the Korean Academy of Medical Sciences (KAMS), the most contentious point in the general terms and conditions of private insurance is spinal deformity. To overcome controversy over disability evaluation, the private insurance sector is now applying criteria for axial skeleton to sacrococcygeal vertebrae through revision of standards. Under these circumstances, it is fair to recognize sacrococcygeal fracture as impairment in terms of the pelvis only when the fracture leaves serious deformity and neurological symptoms with clear relevancy. Though it may not be easy to develop accurate disability evaluation standards, improvement is necessary to remove any irrationalities and make the standards as objective as possible.

Recently, many local governments suffering from traffic congestion have plans to introduce light weight (mid-size) rail transit systems, since the systems' investment costs are known to be much less than heavy rail transits such as the subway in Seoul. Most of the governments expect private partners to be involved in the systems' constructions and operations mainly because of their financial difficulties. Since the governments do not have experiences of evaluating and selecting privately financed transportation systems, they may need an evaluation guideline. This paper discusses evaluation criteria, methodologies, and procedures which will be helpful to local governments faced with evaluating light weight rail transit systems proposed by private companies.

Since the intranet is a combination of open internet technologies and private information systems, various technologies for information security are essentially needed. On recent, a lot of firewall systems are being constructed to be secure the informations from external networks such as Internet in many private companies. Even though internal attacks are more frequently happened than external ones in the intranet environments, there are quite few researches on secure intranet and the internal threats are underestimated so far. In this paper, we study the security threats for each service in the intranet and propose the security models appropriate to the intranet environments by using several cryptographic tools and protocols. Furthermore, we implement the proposed security models in Java applications through computer simulation.

This research put the point on deducing problems of our first-aid system and proposing improvement program. Now first-aid system has lots of weakness, such as short of speciality, limitation to raise finance. To improve these first-aid infrastructure must be expanded and improved, and it also needs enough effort for improvement of quality and arrangement of emergency medical treatment speciality. We should introduce commission to first-aid system so raise fund and make use of speciality. And also we should organize private partnership with hospitals or insurance companies, so that we can construct united system of first-aid system.
