디제잉을 하려면 필수적으로, 턴테이블, 믹서, 스피커와 같은 장비들이 필요하다. 하지만 이러한 장비들은 그 크기가 크고 많은 연결선으로 연결되기 때문에 휴대가 용이하지 않아, 일반인들이 가지고 다니면서 디제잉을 즐기고 음악을 믹싱하기에 적합하지 않다. 많은 사람들이 디제잉과 믹싱을 배우고, 또 언제 어디에서나 쉽게 즐길 수 있게 하기 위해서는 보다 작고, 휴대하기 편하면서도 설치의 번거로움이 없는 새로운 인터페이스를 개발할 필요성이 있다. 이 논문에서는 사람들이 언제 어디에서나 쉽게 디제잉과 믹싱을 즐길 수 있도록 해주는 휴대용 무선 믹싱콘솔 장치를 제안한다.

정보통신 안전 서비스의 제공에 따라 사업자 측면에서 관련 장비의 상호운용성 확보, 연구개발 또는 도입제품 평가의 용이성과 제품생산자 측면에서는 생산원가의 저렴화를 위하여 반드시 표준화가 필요하다. 본 논문에서는 안전기술의 표준화 연구를 수행하는 주요 국제기구인 ISO/IEC JTC1 SC21, SC27과 CCITT SG VII 등의 활동과 이에 대응한 국내 표준화 그룹들과 관련 기관들의 활동을 소개하였다. 또한 이러한 국내외 활동과 통신 사업자의 사업여건을 고려하여 통신 사업자가 정보통신 사업에 잇어서 소요되는 안전기술 및 이의 표준화 방향을 제시하고자 한다.

This paper proposes a user interface for enhancing immersiveness and usability by combining hologram and haptic device with common Leap Motion. While Leap Motion delivers physical motion of user hand to control virtual environment, it is limited to handle virtual hands on screen and interact with virtual environment in one way. In our system, hologram is coupled with Leap Motion to improve user immersiveness by arranging real and virtual hands in the same place. Moreover, we provide a interaction prototype of sense by designing a haptic device to convey touch sense in virtual environment to user's hand.

Maintainability in engineering terms means ease of maintenance / management of the product. Aircraft automatic test equipment (ATE) is heavily influenced by the design changes of the unit under test(UUT) since the test procedure is developed according to the function / performance characteristics of the UUT. Moreover, if the integrated ATE is an environment that checks more than one UUT, it is not easy to maintain the ATE for the UUT design changes. Developers should be able to flexibly cope with the change of development staff by selecting an easy and clear development method to improve the maintainability of ATE. It is also necessary to limit the area affected by the UUT design change to a specific range to minimize the area to be modified. In this paper, we propose ATE development method which focuses on maintenance improvement based on the aircraft ATE development process.

This study is to investigate into the factors that influence the use of a military logistics information system in Korean army. We developed the research model based on DTPB (Decomposed Theory of Planned Behavior) because the DTBP is an appropriate model in a mandatary using environment through the study of previous technology-acceptance models. A questionnaire survey was conducted with Korean army solders and civilian components who use the army logistics information system and 266 valid questionnaires are recovered. The collected data were analyzed by SPSS and AMOS. The results show that perceived usefulness and ease of use did not affect the attitude of the use intention. The influence of colleagues and upper class officers was all satisfactory and computer self-efficiency affected perceived control of behavior. The results of this study will contribute to the further use of the military logistics information system and future development strategy.

현재의 네트워크 시스템은 보안시스템 및 신규시스템이 추가됨에 따라 복잡함이 증가하고, 그에 따라 관리하기가 어려워져 관리자나 사용자가 이용하기에 불편함이 따른다. 또한 사용자의 잦은 변동과 단말의 이동성으로 인해 네트워크 관리하는데 있어 관리자가 해야할 일들이 많아 졌다. 따라서 앞으로의 네트워크 관리도구는 복잡성을 해결하고, 사용자의 편의성에 중점을 두어야 한다. 이러한 요구사항을 정리하여 본 논문에서는 사용자에게는 보다 쉽게 사용하고, 관리자에게는 최소비용과 관리의 용이성을 위한 보안시스템을 설계하였다. 이 시스템은 신규 사용자의 네트워크 접속후 인증을 받기위한 부분에 있어서 리눅스 시스템과 네트워크 장비를 연동해서 관리자가 정책적용시 자동으로 ACL을 구성해 보안관리를 강화하는데 목적을 두고 설계하였다.

Among the geophysical exploration methods, electromagnetic method(EM) has the broadest range of instrumental systems and remarkable range of applications. There are a lot of available techniques and instruments which have different depth of investigation and resolution depending on the operating frequency and source-receiver configuration. Furthermore, it is very easy to apply on the engineering and environmental problems since modern EM equipments are remarkably portable, considering their sophistication. Even though electromagnetic theory is very complex and not easy to understand, rapid avances in recent computer technology have made it possible to conduct accurate forward modeling and inversion of various EM exploration data. Here, we are going to provide brief theoretical principles, survey techniques and case histories of some selected EM methods that can be applied to geotechnical and environmental problems in Korea.

Highway construction is a combination of linear, repetitive, and highly equipment intensive operations. Various types of construction equipment are deployed to ensure undisrupted performance of construction, and thus productivity improvement and cost-saving can be achieved through well-thought-out planning. The selection of construction equipment is dependent upon construction sequence, site conditions, and construction methods. In the process of planning, management should consider various types of construction methods per each type of construction operation. Also, management should map out proper construction equipment operation plan that takes the construction duration and cost measures into consideration. However, limited availability of historic data from the similar types of operations has been a stumbling block to proper construction planning, making the operations performed based upon experience and intuition guided by rules-of-thumb. As a consequence, the planing phase rarely provided an adequate validity in the implementation phase. The researchers developed a process logic for each construction type that management can utilize from early phase of highway construction planning process. Moreover, derived the construction equipment combination optimized for efficiency by using the process simulation technique. The developed method is expected to be useful for the decision-making process that aims to evaluate efficiency of various process plans and to ensure optimal selection of construction equipment for highway construction projects.

The container terminal is the unified transportation system which connects between a land transportation and a sea transportation. This system has many subsystems such as ship operation, yard transfer operation, yard storage system, gate operation, and information manage system. This paper presents a method of modeling a simulator with which user can evaluate the efficiency of the equipment and allocation policies in the container terminal. The final purpose is to estimate the efficiency of each equipments and the distribution policies. In a design step in the simulator development. We suggest the Object Oriented method with which the developer can easily design, because the object oriented method has the advantages of reusability and modularity.
