무선 센서 네트워크상에서 센서노드의 소프트웨어 변경, 패치 등의 작업을 위해서는 일반적으로 센서노드 별로 ISP(In System Programming)를 이용하여 프로그램 해야 한다. 이는 네트워크 내에 존재하는 노드의 수가 소량인 경우 크게 문제되지 않지만, 대량의 노드로 구성된 경우에는 프로그래밍을 위한 시간적인 측면과 투여되는 인력적인 측면에서 매우 높은 비용이 소요된다. 본 논문에서는 현재 많이 사용하고 있는 IEEE 802.15.4 기반의 단일 홉 무선 센서 네트워크 환경에서 노드의 수와 무관하게 고속 병렬로 센서노드 내부의 프로그램을 무선으로 업데이트 할 수 있는 기법을 제시하고 실험을 통하여 그 성능을 검증한다.

The letter of credit is quintessentially international. In the absence of international legal system, a private system based on banking practices has evolved, commanding the adherence of the international letter of credit community and providing the foundation of th reputation of this instrument. To maintain this international system, it is vital that international standard banking practice should not be subject to local interpretations that misconstrue or distort it. The UCP is a formulation of international standard banking practice. It is neither positive law nor a "contract term" in any traditional sense and its interpretation must be consonant with its character as a living repositary of international understanding in this field. As a result, the interpretation and application of specific articles of the UCP must be consistent with its evolving character and history and with the principles upon which sound letter of credit practice is predicated. This study, especially, focuses on article 13 and article 14 of the UCP500. Article 13(b) of UCP500 stipulates that banks will have a reasonable time, not to exceed seven days, to examine documents to determine whether they comply facially with the terms of the credit. The seven-day provision is not designed as a safe harbor, because the rule requires the issuer to act within a reasonable time. But, by virtue of the deletion of the preclusion rule in the document examination article in UCP500, however, seven days may evolve as something of a safe harbor, especially for banks that engage in strategic behavior. True, under UCP500 banks are supposed to examine documents within a reasonable time, but there are no consequences in UCP500 for a bank's violation of that duty. It is only in the next provision. Courts might read the preclusion more broadly than the literal reading mentioned here or might fashion a common-law preclusion rule that does not require a showing of detriment. Absent that kind of development, the change in the preclusion rule could have adverse effects on the beneficiary. The penalty, strict estoppel or strict preclusion, under UCP500 and 95UCC differs from the classic estoppel. The classic estoppel rule requires a beneficiary to show three elements. 1. conduct on the part of the issuer that leads the beneficiary to believe that nonconforming documents do conform; 2. reasonable reliance by the beneficiary; and 3. detriment from that reliance. But stict preclusion rule needs not detrimental reliance. This strict estoppel rule is quite strict, and some see it as a fitting pro-beneficiary rule to counterbalance the usually pro-issuer rule of strict compliance.

온라인상에서 안전하게 금융서비스를 이용하기 위해서는 사용자를 인증하는 기술이 요구된다. 키보드를 사용한 비밀번호 입력 방식이 가장 일반적이나, 키보드 입력이 쉽게 유출될 수 있음이 알려짐에 따라 많은 인터넷 뱅킹 서비스 및 간편 결제 서비스에서는 가상키보드를 사용하고 있다. 하지만 안전할 것이라는 기대와 달리, 가상키보드 역시 키보드 입력이 유출될 위험성이 존재했다. 본 논문에서는 가상키보드의 비밀번호 유출 가능성을 분석하고, PC 환경에서 마우스 이벤트 후킹과 화면캡처를 활용한 비밀번호 유출 방안을 제시했다. 또한, 국내 유명 인터넷 뱅킹 웹사이트 및 간편결제 서비스에서 비밀번호 유출 공격 가능성을 직접 검사하였으며, 그 결과 PC 운영체제에서 수행되는 가상키보드를 통한 비밀번호 입력방식이 안전하지 않음을 검증하였다.

For service innovation, it is crucial to measure the quality of service and identify the factors which affect it. In this study, for that purpose, a composite research model based on SERVQUAL and the technology acceptance model is proposed. The model is applied to three different service areas-Internet shopping, Internet banking, and cloud service. Analysis has been performed using the SEM methodology. The analysis shows that reliability, responsiveness and assurance affects the service quality in different ways for each, the result of which enables us to identify quality-determining factors in various service areas.

A Systematic Wealth Management Framework (SWMF) was developed as a private banking management tool to enable more integrative personal finance management of personal wealth. It is a reference model that provides an unified framework for development, operation, and management and makes provision for personal financial services in today's complex financial environment. This study suggested some practical results from banks and insurance companies that have established SWMF as the differentiation business strategy for wealthy customers. The focus of this manuscript is on capturing the methodological approach most financial institutions in Korea adopted to execute new e-finance planning and implementation based on the SWMF. The alignment between the wealth management business goals and information system architecture at an organization constitutes the main theoretical basis of the study. Relevant discussions are made on the wealth management framework as a general business model for financial industry, on the functional relationship between new information systems and business organizations. Finally, lessons learned from the SWMF implementation are discussed.

The CRM is the process of integrated customer management to increase the profitability of firm as a maximizing the consumer's value and supplying the high quality product or service. The Post Information Service Headquarter was recognizing the importance of CRM and constructed the customer relationship management system that based on CRM, steadily has made an endeavor for operating to improve the job operation such as posting, banking and insurance. This research analysed the impact of service quality on the customer satisfaction in the Korea Post Office. First of all, we review the existing literature on measurement of service quality and management. As a result of this review and survey of the employer in post office, nineteen factors emerged as important to the service management of The Korea Post Office; Postal Services, Banking Services, Insurance Services. The regression analysis was utilized for analyzing the influence of service quality factors upon the customer satisfaction. Results show that service quality factors have a statistically significant impact on the customer satisfaction of the Korea Post Office.

The purpose of this study is to explore an implication for new perspectives and concrete approaches to Korean Land Banking by analyzing the role of the Land Bank and the Land Storage System in the formation of Chinese Land Market, Land Management, and City Management. Time scope of this research focused on Chinese reform and opening since 1978, when study of land bank began to be actively performed in China. Research targets were Land Bank and Land Storage System related to Chinese Land System, and this research targeted Chinese Land Storage System as research object, which seem to have similar tendency to Korean Land Banking System, after examining the concept of Land Bank and Land Storage System. As the research method, this research arranged the contents and changes of policy based on discussed research documents over Chinese Land Bank and Land Storage System till today since the foundation of the nation. Later, this research investigated the realistic reflection and in-depth investigation of the problems through the operational mechanism and concrete case study of Chinese Land Storage System, a similar policy to Korean land bank, the researchers will look into the reality reflected and will carry out a in-depth study of the problems. China has established its characteristic socialistic market economy system, partly adopting the concept of capitalism, supporting socialism. This way, the researcher considers that such socialistic economic factors with strong welfare aspects can be adopted also in Korea, where capitalistic market economy system is maintained, and be utilized as a new measure for development strategy.

학점은행제는 평생학습사회를 구현하기 위한 교육 시스템이다. 이 시스템의 조건을 충족한 학습자는 전문대, 4년제 대학교의 학위와 동등한 학사 학위를 취득할 수 있다. 이 학습자의 학점과 학위 정보는 중앙 기관에 기록되어 관리되고 있다. 그러나 이러한 시스템은 중앙관리로 인해 해킹 등과 같은 보안 문제가 발생할 수 있다. 본 논문에서는 블록체인 기술을 기반으로 학점과 학위 정보를 관리할 수 있는 학점은행제 시스템을 제안한다. 제안된 시스템은 학점과 학위 정보는 블록에 저장되고 영구적인 방식으로 공개 원장에 기록된다. 블록들은 해킹과 조작 등의 보안 문제를 개선하기 위해 분산 네트워크 환경에서 블록체인 형식으로 연결되어진다. 또한 중앙 기관의 기능들이 네트워크 참여자들에게 분산되기 때문에 학점 은행 관리의 효율성이 증대될 수 있다. 제안된 시스템의 프로토타입은 Go-Ethereum 플랫폼에서 구현되었으며 스마트 컨트랙트를 사용하여 참여기관 간의 블록체인 정보를 실험적으로 검증하였다.
