The 070-VOIP service were began to support system of E.164 and an IP address service. The address system was proposed how an convergence of E.164 address system was worked with an EPC and an IP address to the multimedia convergence service within the integration of wireless and wireline. In future, it was presented the way that the end user could use an integrated address system to be based on E.164 in BcN networks. An expansibility will be easy to all things are put into in knowledge that u- address system use an integrated address system to the basis of E.164 system. E.164와 IP주소가 지원되는 070-VOIP 서비스가 시작되었다. 유${\cdot}$무선통합의 멀티미디어컨버젼스 서비스에서 EPC와 IP 주소를 E.164 주소로 융합하는 주소체계를 제안하였다. 향후 BcN네트워크에서 엔드유저는 E.164를 기반으로 하는 통합된 주소체계를 이용할 수 있는 방안을 제시하였다. 유비쿼터스 주소체계는 IP기반의 E.164 주소체계를 이용하여 통합된 하나의 주소체계를 적용함으로서 모든 사물에 지능화시에 확장성이 용이할 것이다.

In a recent year, The Korean Government has steadily carried out a scheme for realizing the officially assessed land price of standard land for taxation to the market price so as to enhance adequacy and credibility. As a result of the scheme, there is no doubt for remarkable achievement for the Government Will in view of quantitative aspect as the officially assessed land price has gradually been increased approaching to the market price since then. During this progress, however, the achievement in view of qualitative aspect has been figured out to be insignificant, and still need to be enhanced as it is on going hot issue against the principle of equity for taxation. In this regard, this study is to demonstrate fairness and equity to see whether or not the officially assessed land price has impartially been carried out by scrutinizing the data obtained through the carefully screened volume of market transaction records from January 01, 2014 to December 31, 2015 and thereby comparing the data with actual assessment rate in the year of 2016 within the jurisdictional boundary of the Busan Metropolitan City Government. In addition, as a result of analyses for demonstration, in cases where inequity and or unfairness are found to have been existent, an effort has exerted to identify the cause of the problem in either local-oriented aspect point of view or political point of view, and suggested political alternatives to overcome it.

스마트농업 교육 서비스는 농업정보의 확산을 촉진하기 위해 제공되며 농업 정보는 현재의 농업활동, 농산품, 농지에서의 생산자 경험으로부터 추출된다. 스마트농업 교육은 웹 오브젝트 기반의 자기주도형 학습으로 제공되어 공간, 장소, 시간에 제약을 받지 않는다. 본 연구에서는 클라우드를 기반으로 하는 학습관리기능과 감시기능, 학습심사기능 등으로 구성된 스마트농업 교육의 기준 구성도를 제시하여 스마트농업의 확산을 위해 필수적으로 요구되는 스마트 농업 교육 서비스 기술 표준 및 스마트 농업의 보급 과정에서 필요한 네트워크 기반 참조 모델을 제시 한다. Smart farming education service focuses on the dissemination of farming information that is the farming knowledge, farming skill, and farmer's experiences and knowhow, etc. This farming information is supposed from current activities, farming product and from the experience of farmer on the field. If the information is not available, or if available and not in a form that is amenable to being brought to the end producer then the process stalls at this point. The core component of the automation process for smart farming education service is the creation of a data store which will be a repository for the information of the smart farming education. The farming sector will benefit immensely from the implementation of farming data in farming contents repository which will serve as the knowledge base for the smart farming education service.

IT 와 농업분야의 융합은 생산, 유통, 소비 분야에서의 효율과 질적 향상을 기대하게 되었고 특히 IT 영역의 정보 분석 기술과 자동제어 기술은 농산물 생산에 많은 장점을 제공하게 되었다. 네트워크 기반에서의 농업 분야 ICT확대는 기술적, 환경적인 측면에서의 어려움들을 해결하게 되었다. 본 논문에서는 IT와 접목한 스마트 농업 환경에서의 표준 기능 모델을 제안 분석하고 이를 바탕으로 한 스마트 농업에서의 기술적 서비스 요구조건 을 제시한다. IT convergence with agriculture is expected to bring more efficiency and quality improvement in producing, distributing, consuming of agricultural products with the aid of information processing and autonomous control technologies of the IT area. Smart Farming based on network is a service which is capable of coping with environmental and technical problems with the actualized IT convergence case for agriculture. In this paper, it is required to consider the actualized IT convergence case for agriculture, namely Smart Farming as a solution to cope the presented problems. In addition, propose and suggest to standard model and standardization items requirement for the Smart Farming based on network.
