High-speed telecommunication has brought variety of changes in every field of the world at large. In the field of education, use of multimedia has been positively introduced as teaching and learning tools. In addition, introduction of remote education as well as information and communication technology (ICT) has led an educational system gone into melting pot. These changes have known to be impossible without the provision of the infrastructure of telecommunications such as cabling, cable pathway, telecommunication equipments, and space for the equipments. Although the infrastructure of telecommunications should be fully considered from the early stage of the building design, most of the existing buildings have only cabling for voice communication such as telephone. As a result, heavy expenses are required for the installation of new telecommunication equipments. Such problems as defilement of the appearance of the building and a falling-off in reliability of telecommunication line are caused by the exposed cabling, when the cabling pathway and/or the space for the equipments are not reserved. Considering over 70% of error in telecommunication is coming from the cabling in building, it is necessary to reserve the space for efficient maintenance of the cabling and the equipments. In recent years, the national standard(TTAS.KO-04.0005) on the reservation of space for telecommunication cabling and equipments in residential and commercial building is established and applied for the building design. As well, the standard is in force for the educational buildings. In this study, we try to provide the guidelines for the design of telecommunications infrastructure in educational buildings for the purpose of efficient operation of education information and ICT.

현재 KT의 관로포설 공법은 관 상부 토피 1m를 확보한 상태에서 차량하중이 작용한다는 가정하에서 제정된 것이며, 토피 1m를 확보하지 못하는 구간에는 별도의 보강공법을 적용하고 있다. 그러나 현재 관로공사의 대부분을 차지하는 도로유관공사는 도로 조성이 종료되는 시점에는 토피 1m를 확보하지만, 도로조성 공사기간 중에는 별도의 보강공사 없이 토피 60cm 내외에서 공사 차량의 하중이 관로에 그대로 전달되고 있어 관로의 찌그러짐 현상이 발생하고 있다. 본 논문은 이와 같은 조건에서도 고품질의 관로를 확보하기 위하여 현행 FC관로 뿐만 아니라 지하매설관으로 사용되는 각종 재질의 관에 대한 특성을 검토하였으며 매설관 변형실험을 통하여 도로유관공사에 적합한 관로재질을 제시하였다.

Information and Communication Technology (ICT) has the potential to provide economic opportunities and help raise the social and political status of countries. For developing countries, ICT can be used as a tool for economic growth and social advancement in a short period of time. The benefits of ICT, however, are not only economic in nature. It can help improve professional skills, teaching quality, job creation, agricultural production, community involvement, and information use, personal relationships, and time use. These benefits are examples of how ICT has become an indispensable part of our lives. Myanmar is a developing country and is ranked low in the ICT Development Index. In terms of ICT development, Myanmar today is facing many issues such as a lack of telecommunication infrastructure, ICT awareness, electricity, and budget for ICT development. Among the economic reforms implemented by the recent government, the telecommunications sector has been opened up as a measure of economic reform. As a result of this reform, the telecommunications sector has been growing rapidly. Myanmar, however, remains behind other Asian countries. This paper discusses Myanmar's ICT infrastructure status, progress that has been made in the country's telecommunications over the last fifteen years, and the challenges that lie ahead.

Author outlines briefly developments of policies relating to telecommunication infrastructure and databases since latter half of 1970′s. There exist three phases. The first phase was from later 1970′s to 1985, which was an initial stage of electronic information service in Japan. In the second phase, 1985～1990, basic policy change made possible the privatization of telecommunication services and proliferation of database products and vendors, The third phase began in early 1990′s with downsizing in computer usage, wide-spreading information networks and rapid dissemination of personal computers. Then author describes offers on policy formation for "novel information infrastructure" and current situation concerning the "Internet" in Japan. Finally, tasks and problems for implementing new generation program for information infrastructure and database usage are pointed out, These are knowledge resource, cost, copyrights and cultural problems including language.

FTTH 가입자망 구축을 하기 위해 기존 시가지나 주택지역에 있는 통신 관로 시설을 분석한 바에 의하면 그 사용률이 약 71%에 이르고 있는 실정이며, 시설도 낙후되어 실제로 현장에서 사용하고자 하면 바로 사용할 수 없는 시설들이 상당히 존재하고 있다. 이를 위해서 본 연구에서는 FTTH을 구축하기 위한 통신기초시설의 수요를 사전에 예측하여 효율적이고 경제적인 투자방향을 모색해 보았다.

도시를 중심으로 지속적으로 발생하고 있는 초고속 네트워크서비스의 안정성을 확보하기 위해 KT는 경제적이고 안정된 구조의 직경 1,000mm 이하의 무인통신구를 건설하고 있다. 도심지에서 무인통신구 공사 허가 및 민원을 유발하는 요인으로 공사시 발생하는 이수 처리장치인 디샌더(Desander)의 소음과 진동이 있다. 소음과 진동은 불쾌감을 유발하고 인근 건물에 영향을 줄 수 있기 때문에 지속적인 관리가 필요하다. 본 연구는 소음과 진동의 주 원인인 디샌더가 발생하는 진동 특성을 모델링하고 설계인자를 이용한 최적화를 통해 진동전달 량의 최소화에 관한 것으로 이를 통해 디샌더의 설계단계에서부터 민원 유발원인인 진동과 소음을 최소화 하고자 한다.

With the proliferation of cloud computing infrastructures, service providers are able to deploy services in on-demand manner. Recently, microservice architecture has been attracting attention in order to maximize the efficiency of resource expansion in cloud infrastructure. Instead of implementing all of the service functions in a single software, service providers can easily and autonomously implement the necessary services by interconnecting the necessary services through an efficiently designed application programming interface (API). Moreover service developer can freely choice programming languages and define software, and functional structures to meet their functional requirements. In this paper, we propose virtual infrastructure manager service based on microservice architecture and evaluates its performance in scalability perspective.
