거래를 포함한 커뮤니케이션이 효율적으로 발전함에 따라 보다 다양한 채널의 커뮤니케이션이 가능해졌으나, 신뢰 메커니즘이 아직 형성되지 못하여 불확실성과 위험 요소를 야기시킬 수 있기 때문에 정보 사회에서의 신뢰성에 대한 문제는 점점 중요한 의미를 갖게 되었다. 정보사회에서 신뢰를 형성하는 방법은 매우 다양하다. 기존에는 이용자의 경험 및 타인으로부터의 정보입수, 공급자의 신용 및 명성, 정부의 법·제도 등을 토대로 신뢰형성이 이루어져 왔으나, 정보사회에서는 전자서명이라는 새로운 기술과 이러한 기술을 사회적으로 이용가능하게 하는 인증 관리 체계의 도입을 토대로 이루어지고 있다. 본 고에서는 전자서명과 인증제도의 국내·외적인 동향에 대해 분석하고자 한다.

인터넷 멀티캐스트 서비스는 네트워크 자원의 효율적 사용이라는 장점과 15년 이상의 연구, 개발에도 불구하고 아직 보편화 되지 못하고 있다. 이는 멀티캐스트 서비스가 망에서 지원이 잘 되지 않고 있고. 멀티캐스트 망 관리의 어려움. Killer Application 부재 등 많은 문제점이 있고, 멀티캐스트 서비스의 신뢰성 보장이 되지 않고 있다는 것도 하나의 문제점 이라고 할 수 있다. 본 논문에서는 인터넷 멀티캐스트 서비스의 신뢰성 보장을 위한 방법으로 기존에 발표된 트리기반의 프로토콜인 RMTP (Reliable Multicast Transport Protocol)[1]. [2]의 단점을 보완하여 신뢰성 있는 멀티캐스트 전송을 위한 방법을 제안하고자 한다.

The purpose of this study was to develop a perception of importance on patient safety management scale (PI-PSM) for Hospital Employee. The PI-PSM was developed and vallidated as follows: item generation, vertification of content validity, pilot study, and test of validity and reliability. In order to verify preliminary instrument, data was collected from 280 hospital employees. Data were analyzed by Varimax factor analysis and Cronbach's ${\alpha}$. There were 21 items in final instrument categorized into 4 factors as 'concern about patient safety management (7 items)', 'confidence about patient safety management (5 items)', 'will for patient safety management (5 items)', and 'recognition about patient safety management (4 items)'. The total varience explanined was 60.4%. The internal consistency, Cronbach's ${\alpha}$. was .86, and reliability of the sucscales ranged from .69 to .87. The results of this study may useful to assess the perception of importance on patient safety management.

As FTA is spreading, it is becoming more and more necessary to improve the accuracy and reliability of the country of origin information at the domestic trading stage in preparation for the actual surveys expected to surge in the near future. However, there are many problems in collecting and managing information related to origin. It is pointed out that the shortage of export-oriented profits and the incentive for issuance of FTA-related profits, as well as the lack of information on the distribution and management of origin information of domestic manufacturing companies are also pointed out as important causes. In this paper, we propose a method to improve the efficiency of management and circulation of smooth FTA origin (comprehensive) certificate of Korean companies and to improve reliability through manipulation prevention by building prototype of origin information management system based on private block chain Hyperledger. The block chain, called Distributed Ledger or Trusted Internet, provides a technical infrastructure that enables various related companies to distribute origin information with high reliability and immediate distribution in the supply chain, but research on its application is still in the beginning stage.

This study aimed to analyze the quality concepts and requirements of digital records as evidence and to find an implication to develop requirements for trusted digital records with securing authoritative qualities. To this end, this study compared requirements of records domain linking records process, records metadata and records systems with judicial domain on digital evidence, and identified the records requirements to secure the legal admissibility linking records and judicial domain. This study analyzed the relationship of quality concepts between digital records and digital evidence, found the legal admissibility is highly related to the reliability, and derived that it needs the measure to secure the reliability at the stage of records creation and capture. To prove authenticity of digital evidence, this study identified importance of records process, records metadata and records system, and proposed the necessity of measurement to secure records' evidence.

This study investigates the effects of supervisors' leadership style on franchisees' trust and commitment in a franchise system. We classified leadership into two styles - transformational leadership vs. transactional leadership, and it was hypothesized and tested that these two leadership styles have differential effects on trust and two different types of commitment - calculative commitment vs. affective commitment. A questionnaire survey was conducted to collect the data and a total number of 184 Korean franchisees in diverse industries participated to the survey. Using a structural equation modeling, we confirmed some differential effects of the two leadership styles. Transformational leadership was found to have positive effects on franchisees' trust in and affective commitment to the franchisor, while it has no effects on calculative commitment. On the other hand, transactional leadership was positively related to calculative commitment to the franchisor. But it had no effects on trust and affective commitment. Meanwhile, we also found that trust positively affects on both types of commitment. The results of this study suggest that the quality of franchisor-franchisee relationships can be improved by supervisor's strong leadership, especially by transformational leadership, and that transformational leadership, when compared to transactional leadership, is more important for developing a long-term and stable franchisor-franchisee relationship.
