In this paper, we design and implement an efficient fair off-line electronic cash system based on Elliptic Curve Discrete Logarithm Problem (ECDLP), in which the anonymity of coins is revocable by a trustee in case of dispute. To achieve this, we employ the Petersen and Poupard s electronic cash system [1] and extend it by using an elliptic curve over the finite field GF($2^n$). This naturally reduces message size by 85% compared with the original scheme and makes a smart card to store coins easily. Furthermore, we use the Baek et al. s provably secure public key encryption scheme [2] to improve the security of electronic cash system. As an extension, we propose a method to add atomicity into new electronic cash system. To the best of our knowledge, this is the first result to implement a fair off-line electronic cash system based on ECDLP with provable security.

This paper investigates the optimal ratio of the ex post cost settled in the total cost paid to the facility-operating agent and the size of compensation for demand promotion efforts made by the trustee. We have extended McAfee and McMillan(1986)'s principal-agent model by incorporating incentives for the demand promotion efforts. We show that cost reducing effort is negatively related with the ratio of the ex post cost settled in the total cost. In addition, the optimal level of demand promotion effort is determined by the size of the compensation and the ratio of the ex post cost settled. A simulation study confirms our findings from a theoretical model.

The water resources project of 320 Ha second stage reclamation, in which including an University City, out of 800 Ha Ndata Farm, Malawa, had been under studied in this research. The challenge of C value of runoff coefficient was obtained as 0.8, by introducing the attenuation factors method, proposed by second author, an IDF dimensionless method customary used in Taiwan, proposed by the third author, is translated further to solve the project design rainfall; Rational Method, thus, obtains 11.5 CMS as the 5 year recurrence storage. The final job, completed by the third author's on-site performance, includs field alignments and discussions with the trustee, Malawa President H. E. Dr. Bingu Wa Mutharika, when a special concern of anti-theft. In order to provide sufficient supply up to an amount of 44,000 M3 during April to November, the sketch package includes 6 measurements: one water barrage, one sluice gate, one intake, one sediment reservoir, one water reservoir, and 3199 Km long gravity-driving hydraulic pipe.

명의신탁이란 신탁자와 수탁자 간의 대내적 관계에서는 신탁자가 부동산소유권을 보유하고 신탁목적물이 부동산을 관리하고 수익 및 처분하면서 등기의 공부상 소유명의만을 수탁자로 하여 두는 제도로서 구법시대 부터 판례에 의하여 인정되어왔다. 부동산소유권과 그 밖의 물권을 실체적 권리관계에 부합하도록 실권리자 명의로 등기함으로써 부동산등기제도를 남용한 불법행위 등 반사회적 행위를 예방하고 부동산 거래의 안정화를 도모하여 국민경제의 건전한 성장에 기여함을 목적으로 1995년 제정된 부동산실명법에 의하여 원칙적으로 명의신탁이 금지될 뿐만 아니라 엄격하게 해석되어야 함에 불구하고 아직도 명의신탁은 척결되지 않고 있는 것이 사실이다. 특히 명의신탁에 있어서 부동산실명법에 의거 명의신탁약정이 무효가 된 경우에 명의신탁 대상의 부동산소유권이 누구에게 귀속되는가 등 여러 가지 문제점이 대두되고 있다. 따라서 명의신탁은 계약자유의 원칙이 지배하는 현시점에서 법률행위 논리가 반영되어야 할 것으로 본다.

Purpose: The article looks at the member' rights and trustees duties and determines where should the emphasis be as it often happens that these two aspects often clash. Research Design, Data and Methodology: It is determined in this article whether the trustees owe fiduciary duties to both the fund and members and further determines whether the trustees should advance the interests of the members. Results: The article further looks at the governance of the retirement funds and argues that the proper governance of these funds protects the interest of the members. The duty to disclosure of information to members is of paramount importance to ensure that members are able to make well informed decisions. Conclusion: The article considers the issues of disclosure of information from other countries, United Kingdom, United States and Malawi. It is argued in this article that trustees must be persons who are trustworthy and have the best interest of the members at heart and must therefore familiarize themselves with the laws that regulate their duties.

The objective of this study is review effective business reorganization measures for tackling financial difficulties for financial managers. The major cause of business failure is incompetent management. Business failure occurs when a company is unable to meet its current obligations, or the net worth of the company is negative : usually the signs of business failure are predictable in advance of its actual accurrence. Discriminant analysis as well as other analytical tools - profile analysis, dichotomous analysis, analysis of likelihood ratios - have been used to predict business failure on the basis of various financial ratios , among those, discriminant analysis has been tell known an excellent technique in predicting business failure. The first question to be raised is whether the business is better off, dead or alive. Assuming the decision is made that the firm should survive, reorganization procedure should be considered. The informal procedures of voluntary settlements used in reorganization are extension : composition and liquidation by voluntary agreement. Unless this settlement is possible by those means, the case goes to the courts for 1ega1 solution. If the court decides on reorganization rather than liquidation, it will appoint a trustee to control the firm for reorganization and to prepare a formal plan of reorganization. the plan must meet the stand of fair, equitable and feasible. In that case, the court will approve the plan.

Trust has been viewed from many perspectives according to their domains. This article reviewed some of many formerly suggested studies and models. And antecedents of trust, such as trustworthiness(ability, benevolence, integrity) and individual trust propensity as well as their interactions, were respectively and empirically tested in the context of Korean workplaces. Through the factor analysis of field survey(N=243), proposed conceptual independence in trustworthiness was only partially supported. Of the relationships between antecedents and trust, all components of trustworthiness were significantly sustained. While effects of individual trust propensity and its interactions with trustworthiness on trust were not found.

Customer's trust is one of major competitiveness sources along with price in Internet Web-based B2C e-commerce business. In general, trust is defined as the attitude that is established by a trustor when trustworthiness exists in a trustee and is perceived by a trustor. Designing e-commerce websites is important in that e-commerce website is understood as a means of constructing perceived trustworthiness and delivering it to customers. In this study 50 participants were interviewed and total of 831 participants responded to the survey questionnaire to investigate design factors influencing the perceived trustworthiness in e-commerce websites. Nine design factors were derived as the perceived trustworthiness-related design factors, and only six out of nine design factors were found as having significant effects on the perceived trustworthiness of e-commerce websites. In addition, the significant design factors were different according to gender and ages of e-commerce customers.

2016년 5월 19일 대법원은 전원합의체판결에서 부동산 매수자가 본인 명의로 소유권이전등기를 하지 않고 등기를 매도인에게서 직접 명의수탁자로 이전하는 제3자간 명의신탁(중간생략등기형 명의신탁)의 경우 명의수탁자가 신탁부동산을 임의로 처분하여도 형사처벌를 할 수 없다는 판결을 하였다. 본 논문에서는 민법과 형법의 교차영역인 명의신탁에서 민사사건의 형사화를 지양했다는 점에서 긍정적인 평가를 하지만 이에 따른 관련법의 정비를 통한 법개정을 제안한다. 즉, 명의신탁에 관한 법제 간 모순을 극복하기 위해 '부동산 실권리자명의 등기에 관한 법률'의 개정이 요구된다. 또한 부동산소유자가 그 등기명의를 타인에게 신탁하기로 하는 명의신탁약정을 맺고 그 등기명의를 명의수탁자에게 이전하는 소위 2자간 명의신탁의 경우도 비범죄화를 함으로써 법체계의 논리성과 통일성을 확보할 필요가 있다.

This study aims at finding what factors influence trust in e-government and how trust in e-government and satisfaction with e-government services affect trust in government. Despite of the importance of trust in e-government, there has not been sufficient research. Giving light on the factors of affecting trust in e-government is of academic significance. Therefore, the purpose of this study is to explore the nature, driving forces and consequences of citizens'trust in e-government and in government. The empirical results indicated that temporal embeddedness, network embeddedness, information provision quality, information security quality and e-participation quality affect satisfaction with e-government services and trust in e-government. Also, satisfaction with e-government services and trust in e-government influence trust in government, and satisfaction with e-government services affect trust in e-government.
