  • 최근의 공정한 정보 교환 프로토콜 연구에서는 중재자를 이용하지만 통신 쌍방 사이에 분쟁이 발생하는 경우에만 중재자가 개입하는 방법으로 중재자의 역할을 최소화시키고 있다. Mao는 공정한 정보 교환 프로토콜에 응용 가능한 검증가능 위탁 서명이라는 새로운 서명 개념을 제안하였다. 그러나, Mor 의 방식은 Staeler의 이산로그에 대한 검증가능 암호 기법을 이용하기 때문에 통신량과 계산복잡도가 매우 높다. 본 논문에서는 제곱근에 대한 검증가능 암호 기법을 이용한 검증가능 위탁 서명 방식을 제안하였다. 제안된 검증가능 위탁 서명 방식은 통신량이 적고 계산 효율성이 높은 장점이 있으나 위탁 기관을 단 하나밖에 허락하지 않는 단점이 있다. 또한, 본 논문에서는 제안된 검증가능 위탁 서명 방식의 응용으로 공정한 전자 계약프로토콜과 공정한 전자 등기 우편 프로토콜을 함께제안하였다.

  • The purpose of this study was to analyze the rationale and format of music therapy interventions with patients receiving hospice or palliative care in Korea. Through this analysis, I examined whether the music intervention used was based on a valid rationale and represented the professionalism expected of today's music therapy interventions. A total of 12 studies that met the selection criteria were identified, and the overall characteristics of each study and its format were analyzed. As a result of the analysis, it was confirmed that the rationale for each study and its format were influenced by the author's research field. The analysis also showed that the research on music-based interventions in hospice or palliative care settings was insufficient and involved a mix of professional and nonprofessional interventions. The results of this study suggest that importance of researchers possessing professional competence which requires offering a clear justification for their choice of interventions, music, and instruments. Additionally, these results emphasize the need for further development of evidence-based music therapy approaches in hospice and palliative care settings as the role of music in supporting patients in these environments has gained increasing recognition and validation.

  • Revocation is one of the main difficulties faced in implementing Public Key Infrastructures(PHs). Boneh, Ding and Tsudik first introduced a mediated cryptography for obtaining immediate revocation of RSA keys used in PKIs. Their method is based on the idea that each user's private key can be split into two random shares, one of which is given to the user and the other to an online security mediator(SEM). Thus any signature or decryption must be performed as a cooperation between a user and his/her associated SEM and revocation is achieved by instructing the mediator SEM to stop cooperating the user. Recently, Libert and Quisquater showed that the fast revocation method using a SEcurity Mediator(SEM) in a mRSA can be applied to the Boneh-Franklin identify based encryption and GDH signature schemes. In this paper we propose a mediated identity based signature(mIBS) with batch verification which apply the SEM architecture to an identity based signature. Libert's GDH siganture scheme is not forward secure even though forward security is an important and desirable feature for signature schemes. We propose an efficient key udating mediated signature scheme, mKUS based on mIBS and analyze its security and efficiency.

  • Arbitration is contractual by nature. One cannot be required to submit to arbitration any dispute which he has not agreed to so submit. As commercial transactions become increasingly complex, involving multiple parties and numerous contracts for a single transaction, however, limiting the parties who are subject to arbitration to only those who have signed a contract containing an arbitration clause would frustrate the purpose of such arbitration clause and might lead to injustice among the relevant parties. Therefore, U.S. courts have recognized a number of theories under which non-signatories may be bound to the arbitration agreement of others: (1) incorporation by reference; (2) assumption; (3) agency; (4) veil-piercing/alter ego; and (5) estoppel. Incorporation by reference and veil-piercing theories have already been recognized by Korean courts. Agency theory and estoppel theory are not recognizable under Korean law. However, the same or similar result may be achieved by applying the third party beneficiary theory or assumption by third party theory. Although a couple of Supreme Court cases appear to be at odds with the assumption theory, on the basis of the recent amendments to the Arbitration Act, such court precedents can be and should be reversed.

  • As arbitration becomes an increasingly popular mode of resolving disputes, neighboring industries begin to take notice. This interest is reflected in the increasing utilization of third party funding in international arbitration claims. In this regard, the third party funding industry appears particularly interested in investor-state arbitration claims because they typically involve considerable claim amounts and substantial legal fees. To examine this trend more closely, this paper, firstly, examines the investor-state arbitration more precisely in Chapter II. In Chapter III, this study continues to examine some legal issues which can arise as a result of a conflict of interest between the parties to the funding agreement including, inter alia, 1) a dispute in which the funder terminates the agreement during the arbitration proceedings, 2) a dispute in relation to a funder's intervention in arbitration proceedings, and 3) a dispute on the responsibility for adverse costs orders, if any. This paper further identifies major legal issues which can arise in relation to 1) disclosure of existence of the funding agreement, 2) attorney-client privilege. Lastly, in Chapter IV, this paper provides some lessons from an in-depth case study on third party funding agreements and solutions to avoid and to solve prospective disputes in the future.

  • We propose a Quantum Authentication and Key distribution protocol based on one-time n using one-way Hash function. The designated users can authenticate each other and the arbitrator using their one-time ID and distribute a quantum secret key using remained GHZ states after authentication procedure. Though the help of the arbitrator is needed in the process of authentication and key distribution, our protocol prevents the arbitrator from finding out the shared secret key even if the arbitrator becomes an active attacker. Unconditional security can be proved in our protocol as the other QKD protocols.

  • Recent Discussions on Third-Party Funding (TPF) in the forums of UNCITRAL, ICSID, and ICC are making different levels of progress towards finalizing the rules. However, they also have similarities in dealing with legal issues related to TPF, such as definitions, disclosure, allocation of costs, and security for costs. International treaty tribunals have dealt with TPF issues, too. When it comes to the standing of funded claimants, the tribunal in Ambiente v. Argentina did not accept the argument that claimants were controlled by the TPF provider. Concerning the scope of the disclosure, the tribunal in Tennant v. Canada ordered the disclosure of the TPF arrangement. As for the allocation of costs, the tribunal in Kardassopoulos v. Georgia noted that there is no reason why a TPF agreement should be treated differently than an insurance contract. Regarding the security for costs, the tribunal in South American Silver v. Bolivia considered the mere existence of a third-party funder as not an exclusive factor to determine costs in the earlier stage of the proceedings. Lastly, relating to TPF as a ground for annulment, the tribunal in Teinver v. Argentina declined the respondent's argument that the TPF agreement was the vehicle of fraud.

  • The purpose of this study was to investigate and compare how the Enneargram personality types of teachers in early childhood education and care would affect their job satisfaction and stress coping strategies. The findings are as follows. First, as to the distribution of the participants' Enneargram personality types, the most common was the Peacemaker type and the least common was the Achiever type. Second, for teachers' job satisfaction, there was a statistically significant difference in the job-related subcategory according to their personality types. The post-hot comparison showed that the Loyalist type showed the lowest score in job-related job satisfaction. Third, in terms of stress coping strategies, there was a statistically significant difference in the psychological coping strategy according to their personality types. The post-hot comparison showed that the Individualist type showed the highest score in psychological coping strategy. The implications for future studies are also discussed.
