Sharing of product and process information with partners is a basic activity and key requirement which ensures success of distribution. ePedigree that encapsulates all of the event data from manufacturer to retail shop provides a flexible mechanism of storing and sharing traceable information to the partners of supply chain and credibility of shared information through digital signature based on Public Key Infrastructure (PKI). To generate the signature that can be authenticated through PKI, the partners of supply chain should pay for PKI certificates from Certificate Authority (CA). In case of agrifood cooperatives which consist of petty merchants or farmers, it is hard to pay for the PKI certificate for all members and is a big obstacle for the ePedigree to be applied to the supply chain. This paper proposes a private certification method of ePedigree for cooperatives. Cooperatives can apply the ePedigree using the proposed method to all the members at small cost and the proposed method can assure the credibility of information at the same level of the previous ePedigree.

Medical information is an important personal information for patients, and it must be protected. In particular, when medical personnel approach electronic medical records, authentication for enhanced security is essential. However, the existing public certificate-based certification model did not reflect the security characteristics of the electronic medical record(EMR) due to problems such as personal key management and authority delegation. In this study, we propose a fingerprint recognition-based authentication model with enhanced security to solve problems in the approach of the existing electronic medical record system. The proposed authentication model is an EMR system based on fingerprint recognition using PEMS (Private-key Escrow Management Server), which is applied with the private key commission protocol and the private key withdrawal protocol, enabling the problem of personal key management and authority delegation to be resolved at source. The performance experiment of the proposed certification model confirmed that the performance time was improved compared to the existing public certificate-based authentication, and the user's convenience was increased by recognizing fingerprints by replacing the electronic signature password.

In modern times, damage caused by the spread of the Internet has become very diverse. In particular, due to the craze of K-pop since 2008, the damage caused by copyright infringement in the domestic and international music markets has become the biggest problem in the Internet market. However, the manpower of the police and copyright protection agencies to solve these increasingly intelligent crimes is insufficient. Therefore, we are trying to find out the role of the public interest detective as a supplementary force for the public authority and as a substitute for the copyright protection agency that can provide legitimate help for victims in the prevention of music copyright infringement and disputes. For this study, first, the concept and types of music copyright, the concept of public interest detectives, the current status and system of music copyright were identified, and the role of detectives for music copyright protection was explored through system operation and status analysis of protection agencies and literature review. Through the results of this study, it is hoped that the role of a professional detective in the public interest dimension of music copyright protection can be a good soil for the development of the detective industry in the future.

Travel speed is an important parameter for measuring road traffic and incident detection system. In this paper I suggests a model developed for estimating reliable and accurate average roadway link travel speeds using image processing sensor. This method extracts the vehicles from the video image from CCTV, tracks the moving vehicles using deep neural network, and extracts traffic information such as link travel speeds and volume. The algorithm estimates link travel speeds using a robust data-fusion procedure to provide accurate link travel speeds and traffic information to the public. In the field tests, the new model performed better than existing methods.

There are many safeguards and measures available regulating the protection of a trademark and its registered holder, however, the protection of a licensee in a trademark license agreement is also important for protection of a intellectual property. Therefore, there are several measures in place for the protection of licensees' interests in Chinese trademark law. Article 43(3) of the Chinese Trademark Law rules a licensor who licenses others to use his registered trademark shall submit the trademark licensing to the trademark office for file, and the trademark office shall announce the trademark licensing to public. Without filing, the trademark licensing shall not be used against a bona fide third party. It means a licensee can not use an unrecorded license with the relevant trademark authority against third parties - essentially, this means that a licensee should insist on having their trademark license agreements recorded against the relevant trademark authority, so that a licensee's interests are protected as against the assignees, licensees and other types of third parties. Otherwise a third party in good faith can use the registered trademark legally against a licensee even though a trademark license agreement between a licensor and licensee is still valid.

전자상거래는 비대면(非對面) 거래로 모든 제반과정이 진행되기 때문에 상대에 대한 신뢰성의 문제가 크며, 거래 당사자와 거래 내역에 대한 입증을 해줄 인증기관이 필요하게 된다. 현재 미국의 베리사인 등 사설인증업체가 국내전자상거래 업체의 인증업무를 담당하고 있는 실정이다. 또한, 인중은 필연적으로 관련 기술의 표준화가 수반되는데 이에 대한 국내기술이 미흡하므로 국제동향을 고려한 국내인증기술의 개발이 시급하다. 특히, 글로벌 전자상거래에서는 인증기관에 대한 문제가 더욱 절실한데 문제는 어떠한 형태로 어떤 기관이 주축이 되어 인중체계를 구축하는가 하는 것이다. 현재, 인증체계는 네트워크 방식, 계층구조, 혼합형의 세가지가 논의되고 있으며, 각각의 장단점이 존재하므로 이에 대한 심도있는 논의가 필요하다. 이러한 체계는 국가별로 상이할 수 있지만, 문제는 글로벌 전자상거래를 활성화하기 위해서는 보다 일관된 형태의 인증체계 구축이 필요하다는 점이다. 현재까지 이와 관련한 심도있는 논의는 미흡한 실정이며, 미국 EU 등 일부국가와 UNCITRAL, OECD, ICC 등 관련 기구에서 다양한 의견을 제시하고 있는 상태이다. 이러한 문제는 단시일 내에 해결되기는 어려울 것으로 보인다. 다만, 단기적으로는 관련국가들간의 상호인증을 통한 해결이 가능할 것으로 판단되며, 이러한 상호 인증이 전세계적으로 확산되어감에 따라 글로벌 전자상거래를 위한 인증체계가 심도있게 논의될 것으로 판단된다. 이와 관련하여 상호 인증과 관련한 국내관련 법제의 보완이 필요하며, 실제로 인증을 담당할 관련 당사자들의 자구노력이 매우 시급한 시정이라 하겠다.

Airport is not only a public facility but a place where multiple cultural and ethnic groups are visiting. It has been reported though several researches that the level of emotional labor is more heavier than any other job. The more complex our society become, the more frequently emotional labor has been focused. Emotional labor became recently the issue of integrated studies above. Considering the level of emotional labor of airport employees, this paper believes their emotional labor has not been focused compared to such as tourism and service industry. This paper tried to research empirically the impact of internal marketing on airport employees' customer-oriented attitude based on their emotional labor using SEM (Structural Equation Modeling). According to the SEM results, it was proven that 'Autonomy of Airport Employee', a latent variable of internal marketing has a significant negative effect on employees' outside emotion. The outside emotion has also a significant effect on their customer-oriented attitude. It could be concluded the effort to increase decision making authority of employees should be implemented to provide them with deeper customer oriented insight.

Most applications using the PKI allows a user to execute the certificate validation processing. The efficiency of user system can be declined by the user-side processing resulting the overhead and low speed of the validation processing. Therefore, in this paper, we propose a new certificate validation processing method can decrease the overhead on user by allowing CAs of the hierarchical PKI to participate in the validation processing. Therefore, our proposed scheme can not only reduce the considerable overhead caused by the user-side whole processing without a new implementation of the delegated server but also improve the time spent for the processing by the reduction of the validation processing job on user.

Consultation program for pharmaceutical development is a new system in which pharmaceutical companies meet and discuss scientific and/or regulatory issues with drug regulatory authority in the research process and before submitting new drug applications. This program helps pharmaceutical companies reduce uncertainties in the research and development and increase the possibilities of getting drug marketing approval. Developed countries such as US, EU, and Japan have implemented various forms of pre-submission meetings or consultation programs since the mid-1990s. The rapid development of technology in pharmaceutical R&D increases the importance of communication between drug development companies and drug regulatory authority in Korea, too. In designing the consultation program, it is desirable to focus on the stages of clinical trials which take the longest period of time and the biggest amount of money in the pharmaceutical R&D process. We suggested that results or recommendations by drug regulatory authorities in pre-submission meetings or consultations be formally documented and considered in review process. Explicit scientific reasons are required for changing the results from consultations.

Regulation for the testing and operation of autonomous vehicles on public roadways has been recently developed all over the world. For example, the licensing standards and the evaluation technology for autonomous vehicles have been proposed in California, Nevada and EU. But specific safety evaluation scenarios for autonomous vehicles have not been proposed yet. This paper presents safety evaluation scenarios for extraordinary service permission of autonomous vehicles on highways. A total of five scenarios are selected in consideration of safety priority and real traffic situation. These scenarios are developed based on existing ADAS evaluation and simulation of autonomous vehicle algorithm. Also, Safety evaluation factors are developed based on ISO requirements, other papers and the current traffic regulations. These scenarios are investigated via computer simulation.
