미국의 전파관리 정책은 1990년대에 들어서 새로운 변화를 맞이하고 있다. 특히 경매에 의한 전파통신 사업면허의 부여, 전파사용료(Regulatory Fee)제도의 도입 등과 같은 새로운 제도의 시행과 이러한 제도의 시행을 뒷받침하기 위한 새로운 행정기구의 설립이나 기존 기구의 역할변화 등의 정책변화를 시도하고 있다. 본 논문은 FCC, NTIA 그리고 이들 두 기관사이의 협조와 조화업무를 담당하는 IRAC 등 미국의 전파관리 행정기구의 구성과 역할을 분석하고자 한다. 이러한 분석을 통하여 연방국가인 미국에서의 연방 정부와 민간간의 전파자원 이용에의 조화와 장기적인 전파지원 개발을 위한 각 기구의 노력을 엿볼 수 있다.

The purpose of this paper is to develope a training model and to make a syllabus for electro-technical officers(ETOs) on ship. In order to complete the purpose, firstly we study on qualification for electro-technical officers and also examine the foreign, domestic cases. Secondly, through the STCW convention and the IMO Model Course 7.08, we have compared the standards of competence for officers in charge of an engineering watch and ETO, and analyze the additional standards of competence to acquire the ETO's licenses. Finally, based on the results of this, we will suggest the development of a training model that officers in charge of an engineering watch must complete in order to obtain an ETO's license. This paper is expected to be useful in the educational institution preparing for training course.

We have studied on the possibility of precise positioning using hybrid Track Circuit system. Hybrid Track Circuit uses RFID which replaces UHF. Hybrid Track Circuit is a part of next generation railroad signal system which is available to communicate with a railway on board system based on a realtime operating system. If applicate on a current hand operating subway, phenomenon caused by driver's mistake such as passing a stop without stopping or mismatch error between PSD and train door should be prevented.

Generally, Urban railway have special characteristics with short distance journey and minimum headway intercity transportation. These days, urban railway operators choose the driverless operation system without driver. On the contrary, Conventional & high speed railway utilize for long distance and high speed running. Because of special conditions of freight railway operation compared with urban railway, operation of conventional & high speed railway is showed very different characteristics. In this paper, We compares different operation scheme of urban railway and conventional & high speed railway and then present condition for train control system based on radio.

IMO adopted comprehensive revisions to the International Convention and Code on Standards of Training, Certification and Watchkeeping (STCW) at diplomatic conference in Manila, Philippine in June 2010. In Korea, the legal amendment of Korean Marine Officers Act has been proposed to apply revised STCW convention to The Korean Law. The Korean Marine Officers Enforcement Ordinance Act currently working on follow-up and this legislation was passed in Legislation and Judiciary Committee. This thesis would like to look into the current status of how to apply the Electro-Technical Officers standard and license system from the Korean Marine Officers Act to be revised. Also, This study aims to effectively improve for Korean Marine Officers Enforcement Ordinance of Electro-Technical Officers system and to provide the policy proposal.
