t Global logistics companies are developing and introducing logistics systems to provide competitive logistics services. Especially as IT develops and mobile functions become more convenient, the Mobile TMS(Transportation Management System) is being introduced as a more convenient system for delivery workers and office managers. However, the success of such a system depends on the system developer who understand the site accurately and office managers and couriers who are using it in the field. The purpose of this paper is to understand which characteristics influence in exploiting new systems focusing on the attitudes of users who use the system daily, and we analyze it through the TAM(Technology Acceptance Model). According to the analysis result, when smart phone has become popular, users have concluded that usefulness is more significant than ease in acceptance of the systems. As a result, we draw suggestions that the focus should be on usefulness rather than ease of system at the stage of system developed.

The purpose of air traffic flow management is to balance demand and capacity in the national airspace, and its performance relies on an accurate capacity prediction of the airport or airspace. This paper developed a regression model that predicts the number of aircraft actually departing and arriving in a terminal maneuvering area. The regression model is based on a boosting ensemble learning algorithm that learns past aircraft operational data such as time, weather, scheduled demand, and unfulfilled demand at a specific airport in the terminal maneuvering area. The developed model was tested using historical departure and arrival flight data at Incheon International Airport, and the coefficient of determination is greater than 0.95. Also, the capacity of the terminal maneuvering area of interest is implicitly predicted by using the model.

As systematic information protection and management is recognized as an organization's core value, organizations are pursuing a shift from an individual-centered information management method to an organization-oriented information management method. The Enterprise content management system(ECMS) is a solution that supports document security and information sharing by insiders and is being introduced by many organizations due to recent technological developments. The purpose of this study is to present a method of improving performance through continuous use of the ECMS from the user's point of view and also suggest a method to improve the intention of continuous use through the expansion of the technology acceptance model. This study surveyed the employees of organizations that adopted the ECMS and verified the research hypothesis derived from previous studies through structural equation modeling. As a result of the analysis, usefulness, and ease of use affected on the intention of continuous use of the ECMS, and the knowledge sharing culture and the ECMS quality factors affected the technology acceptance model factors. The results of this study have academic and practical significance in terms of suggesting a plan to increase the usability of the ECMS from the user's point of view.

As recently, ' International convention for the control and management of ship's ballast water and sediments ' was adopted, it is necessary to accept the international convention in Korea. The systems of foreign countries for ship's ballast water control and management were investigated, and domestic environment-related laws were reviewed and compared regarding the discharge of industrial wastewater and ship's ballast water. Alternative measures of domestic legislation were suggested for acceptance of the international convention.

전력선 통신은 디지털 변복조 통신 기술의 발달에 힘입어 높은 신뢰성과 고속의 데이터 전송 속도를 제공하게 됨에 따라 차세대 통신 기술로 기대되고 있다. 아울러 배전 계통에서의 원격 검침은 단순히 검침 비용의 절감 차원이 아닌 수용가 정보 취득 및 수요관리 등의 기능을 함께 수용할 수 있어 보다 효율적인 에너지 사용관리 및 감시가 가능한 배전 계통 구축이 가능하다. 아울러 구성된 통신망을 이용하여 제공되는 다양한 부가서비스를 통하여 CRM(Customer Relationship Management)의 차원을 한 단계 높일 수 있는 방안의 하나로서 인식되어 선진국 전력회사들간에 지대한 관심의 대상이 되고 있다. 본 논문에서는 전력선 통신을 이용하여 저압 수용가의 원격 검침 시스템의 구축 방안을 소개하며, 시스템 구축 상에 관련된 기술적 사항과 효과적인 네트웍 구축을 위한 프로토콜 등을 다루었다.

최근 스마트폰, 태블릿PC 등 스마트 단말기의 보급 확대로 전자책 시장이 국내외에 지속적으로 성장하고 있지만, 실상은 생각보다 더디게 진행되고 있다. 2015년 전자책 독서실태 결과 지난 1년간 전자책 독서량은 지난번 조사에 비해 0.2권 감소한 1.4권에 그쳤으며 전자책 구독층이 가장 많은 10~20대의 전자책 이용 비중도 줄었다. 이에 본 연구는 대학도서관의 전자책 서비스에 있어서 지각된 가치와 지각된 위험을 기술수용모델(TAM)에 추가하여 서비스 이용자의 수용 후 지속적 사용의도를 실증적으로 분석하고자 한다. 이를 통해 향후 대학도서관 전자책 서비스, 더 나아가 정보서비스의 개발과 보급에 있어 유용한 시사점을 제고하고자 한다.
