DRM(Distal Right Management)은 컨텐츠의 불법 사용을 방지하여 저작권을 보호하고, 컨턴츠의 생성·유통·사용 관리 등에 필요한 모든 처리를 지원하는 종합 솔루션이다. DRM 체계에서 사용자(customer)는 컨텐츠를 정당하게 사용하기 위해서 클리어링하우스(clrearinghouse)로부터 라이센스를 발급받아야 한다. 일반적으로 라이센스(license)는 사용자의 공개키로 암호화된다. 그래서 사용자의 계산적 부담이 크다. 특히 무선 DRM 환경이라면, 사용자의 부담은 더 클 것이다. 따라서 본 논문은 익명성을 갖는 제안 1회용 대리서명 기법과 Y.Zheng의 Singcryption 기법을 적용하여 사용자의 계산량을 줄이고, 익명성을 갖는 효율적인 라이센스 다운로드 방식을 제안한다.

'Unlicensed medical practice by a non-medical practitioner' often represented by surrogate surgery or so-called 'ghost surgery,' causes irreparable damage to life or body, and therefore calls for very strict and effective controls. The 'bill on installment of CCTVs in an operating room' to prevent unlicensed surrogate surgery has been discussed for a long time, but due to numerous issues and heated confrontations, it has been pending in the National Assembly. Nevertheless, it is expected that the bill will be discussed again in earnest in the National Assembly because surrogate surgery and factory-type cosmetic surgery, which has been performed mainly in the field of cosmetic surgery, has also been occurring in the field of therapeutic surgery. In general, an operating room is considered as being locked or closed, as well as disallowing implicit complicity among insiders. Hence, if the insiders conspire to commit or cover up an illegal act, or if a surgeon performs rapid cosmetic surgery and then leaves the recipient (or medical institution) so as to perform more operations for profit - even if it is legitimate practice - it may result in serious consequences in terms of the recovery of a patient. In this case, installation of CCTVs can be of great help in identifying an illegal act and assessing any occurrence of negligence. On the other hand, while the fundamental purpose of therapeutic surgery is to restore a patient's life or body - that is, lifesaving - installation of CCTVs may base the relationship between a surgeon and a patient on distrust and surveillance, so it may increase the number of requests for CCTV footage or lead to more disputes, as well as placing a burden on the surgeon when best results are not achieved for a patient. As a result, the surgeon may choose non-invasive treatment contrary to conscience instead of risky but necessary surgery, or he/she may have significant difficulty in determining the timing of surgery, which may limit the provision of effective surgical medical care. Then, in terms of the relationship between a surgeon and patient, and in the long run, there could be significant disadvantages for the public and patients if CCTV footage is allowed. In this paper, we review domestic and overseas cases and issues regarding installation of CCTVs in an operating room, and present various viewpoints and suggestions to promote legislation with minimized legal problems and side effects, thereby contributing to protection of the lives and health of the public, patients, and recipients of surgery.

Generally, the liability for breach is defined as the civil liability that arises from the conduct of violation of a contract. There are two notable principles governing liability for breach that have fundamental impacts on the unified Contract Law of the People's Republic of China (hereinafter Chinese Contract Law) in the remedies. In China, during the drafting of the Contract Law, there was a great debate as to whether damages for breach of contract ought to follow the fault principle or to follow the strict liability principle. Ultimately the Chinese Contract Law follows the model of the CISG on this point, namely, it follows the strict liability principle (article 107) with an exemption cause of force majeure. Under Chinese Contract Law, it is interpreted as strict liability in principle. Strict Liability is a notion introduced into Chinese Contract Law from the Anglo-Saxon Law. The strict liability or no fault doctrine, on the contrary, allows a party to claim damages if the other party fails to fulfill his contractual obligations regardless of the fault of the failing party. Pursuant to the strict liability doctrine, if the performance of a contract is due, any non-performance will constitute a breach and the fault on the party in breach is irrelevant. This paper reviews problems of legal character or legal ground of contractual liability in Chinese contract law. Specifically, focusing on the interpretation of Chinese contract law sections and analysis of three cases related contractual liability in freight agency, the paper proposes some implications of structural features of Chinese contract law and international commercial transactions.

Recently companies have increased the new projects to improve and innovate the business process in order to adopt the advanced technologies such as IoT (Internet of Things), Big Data Analysis, Cloud Computing, mobile and artificial intelligence technologies for sustainable competitive advantages under rapid technological and socioeconomic external environmental changes. However, there are obstacles to achieve the project goals, corporate's strategy and objectives due to various kind of risks based on characteristics of projects and conflicts of stakeholders participated on projects. Hence, the solutions are required to resolve the various kind of risks and conflicts of stakeholders. The objectives of this study are to investigate the impact of the project governance, agency conflicts on the project success based on agency theory by using the statistical hypothesis testing the relationship among those variables. As a result of hypothesis testing, we could find that the project governance impacts positively on project success and negatively on the agency conflicts. Further, the agency conflicts impacts negatively on the project success. Finally, we could find that the agency conflicts such as goal conflict, different risk attitude and information asymmetry between project manager and team members impact negatively on the project success. Meanwhile, the project governance impact positively on the project success, negatively impact on the agency conflicts such as goal conflict, different risk attitude and information asymmetry between project manager and project team members. In order to increase the project success rate, the project governance institutions such as PGB (Project Governance Board), EPMO (Enterprise Project Management Office), PSC (Project Steering Committee) are needed to prevent or reduce the agency conflicts between project manager and team members.

We present a new MDA-based Mobile-IPv6 multicast routing algorithm for wirelese service operators to offer Mobile-IP over IMT-2000 service under IMT-2000 network by taking advantage of the existing infrastructure for IMT-2000 multimedia application services. The extended IMT-2000 system architectures use an PDSNs (i.e. IWFs), and the home network (i.e. Internet) backbone and intermediate network are composed of ATM entities. A key feature of the new protocol is the use of MDA(Multicast Delivery Agent) to reduce delivery path length of the multicast datagram. We show that proposed protocol is efficient in terms of various performance measures such as multicast traffic load, multicast related handoff, and average routing length when we implement it using the Mobile-IPv6. Particularly, the number of tunneling and average routing length of datagram are reduced relatively, the multicast traffic load is also decreased.

The Streptomyces peucetius OIM (Overproducing Industrial Mutant) strain is a recursively-mutated and optimally-screened strain used for the industrial production of polyketide antibiotics, such as doxorubicin (DXR). Using the S. peucetius OIM mutant strain as a surrogate host, a model minimal polyketide pathway for aloesaponarin II, an actinorhodin shunt product, was cloned in a high-copy conjugative plasmid, followed by functional pathway expression and quantitative metabolite analysis. The level of aloesaponarin II production was noted as being significantly higher in the OIM strain than in the wild-type S. peucetius, as well as in the regulatory network-stimulated S. coelicolor mutant strain. Moreover, the aloesaponarin II production level was seen to be even higher in a down-regulator $wblA_{spe}$-deleted S. peucetius OIM strain, implying that the rationally-engineered S. peucetius OIM mutant strain could be used as an efficient surrogate host for the high expression of foreign polyketide pathways.

Existing studies have shown consistent results that a diversification discount phenomenon occurs, which means that the value of the company decreases as the degree of diversification of a company increases. Nevertheless, it is explained by the agency theory as a factor that continues to promote diversification by companies. And in order to solve the agency problem, it is important to form an effective governance structure. In order to solve these problems, this study aims to study how the directors' concurrent information affects the monitoring effect of the board of directors through this affects diversification.To this end, research was conducted on KOSPI companies for 6 years from 2011 to 2016.As a result of the analysis, in the case of the concurrent appointment of the CEO and the inside director, there was a positive (+) effect, but the significance could not be confirmed. In the case of adjunct appointments as outside directors, positive results were confirmed that were significant for diversification.

국내에서는 매년 많은 수의 자격시험이 치러지고 있다. 현재 대부분의 시험장에서 응시자 본인 확인 절차는 감독관이 응시자의 얼굴과 신분증 사진을 비교하는 방식으로 이루어진다. 하지만 이 방식은 사람에 따라 오차가 클 수 있으며, 사진과 눈에 띄는 차이가 없으면 동일인물로 판단하기 쉽다. 최근까지도 대리응시 이슈가 발생하고 있어 근절을 위한 보다 강력한 조치가 필요하다. 본 논문에서는 지문과 오토인코더, SGAN을 이용하여 대리응시방지를 강화할 수 있는 본인 확인 시스템을 제안한다. 이때 응시자의 지문정보가 그대로 인증 서버에 저장되면 응시자의 생체정보가 노출될 수 있다는 문제점이 존재한다. 따라서 오토인코더를 통해 지문의 특징점만 추출하여 인증용 이미지를 생성하고 이 이미지를 서버에 저장하여 학습시키도록 한다. 적은 학습데이터 환경에서 분류기로써 좋은 성능을 갖는 SGAN을 통해 인증 이미지와 응시자가 동일인물인지 확인할 수 있다. 서버가 공격을 받더라도 응시자의 지문데이터가 그대로 노출되지 않게 되어 보안 취약점을 극복할 수 있다.
