Large-scale urban developments with increasing population and expansion of industrial facilities have destroyed the ecosystem. Consequently, the importance of vertical farm as a form of urban agriculture is increasing. However, such problems of vertical farms as economy and lack of awareness of residents are being raised. Firstly, this study derived types of vertical farm that are applicable to residential spaces through an examination of vertical farm buildings, and then inferred assessment items for a questionnaire survey for the development of u-services. Secondly, based on the issues deduced from the survey, u-services needed in vertical farm buildings were derived to use them as the basic data when we plan for a ubiquitous vertical farm building in residential space in the future. As result, the following uservices of ubiquitous vertical farm were proposed: u-notification service about the condition of crops from the aspect of growth management based on ubiquitous technology, remote/automatic control u-services, harvest information u-service for harvest management, recipe information u-service, and indoor air quality monitoring u-service, indoor environment adjusting u-service, and farm environment control u-service. Considering that many new buildings in Korea are residential buildings and many high-rise buildings are being planned, studies on vertical farm buildings must be continued.

As technology develops, more advanced technologies involving GPS, GIS, RFID and sensor networks have been adopted in agriculture sector for u-Farm. However, technology adoptions have been evaluated as ineffective. Farmers and agri-business have low level of understanding on technology so it is not efficiently utilized. This study introduces a case of RFID/sensor networks of mushroom farm as a u-Farm case study, focusing on developing a framework for analysis of u-Farm investment returns. RFID and sensor networks improve real-time production control, processing management, and traceability. Integration of RFID and sensor networks leads to innovation into the mushroom farm, reducing labor cost, increasing productivity, and improving quality of the mushroom. The ROI which is used as an indicator of performance indicator is 413%.

Generally, because individual agricultural product possesses its own distinctive characteristics and shows different characteristics at each stage of the agricultural supply chain, it is necessary to develop a proper enterprise architecture for managing information system. In this paper, we propose an enterprise architecture based on RFID/USN technology that can be used as a reference enterprise architecture for u-IT application in the agriculture sectors, which is called the u-Farm enterprise architecture with taking heterogeneous characteristics of agricultural products into account for. In addition, we also developed the RFID/USN middleware platform as a core infrastructure technology. Fo evaluation of the performance of the proposed u-Farm architecture and the RFID/USN middleware platform, the field-trial evaluation at the apple Agricultural Processing Center (APC) has been executed and the results shows that the proposed architecture and platform perform well in terms of information integration over the whole SCM process from the farming stage to delivering statge to the customers. It is expected that the proposed u-Farm enterprise architecture can be utilized as a standard information architecture, and the RFID/USN middleware platform can be a infrastructure platform for future u-IT based information technology applications and services in the agricultural environment.

Through USN field Test Projects launched in 2005, 9 USN application service models such as u-Ocean, u-Construction, u-Farm, u-Hospital has been deployed. We conducted technical, industrial, economical feasibility tests to verify those services. This thesis will cover briefly the current situation of USN industry domestically and internationally. It will show the future prospect of convergence service model based on USN in conjunction with research details and results from previous USN field Test Projects.

Purpose - The production efficiency of agricultural crops has been the subject of numerous studies in the field of agricultural economics. This study examines the production efficiency of emerging vineyards in the 14 northern U.S. states and aims to understand raw input and managerial factors affecting the grape production with focusing on the effect of farm size. Research design, data, and methodology - Using a unique survey dataset that was collected from 176 vineyards in 2012, we employed data envelopment analysis (DEA) for estimation of production efficiency in individual vineyards. Production efficiency is regressed on various input and managerial covariates to understand factors influencing the productivity. Results - Although there exists positive correlation between the farm size and productivity of vineyards in Northern U.S. states, we find negative relationship when the farm size is instrumented by the additional farm size expansion indicator. The negative effect is more pronounced for the recently established vineyards. Conclusions - This study suggests that there needs to be adequate managerial improvements for emerging vineyards in northern states for the achievement of increased productivity.

Recently, the u-IT applications for plants and livestock become larger and control of livestock farm environment has been used important in the field of industry. We implemented wireless sensor networks and farm environment automatic control system for applying to the breeding barn environment by calculating the THI index. First, we gathered environmental information like livestock object temperature, heart rate and momentum. And we also collected the farm environment data including temperature, humidity and illuminance for calculating the THI index. Then we provide accurate control action roof open and electric fan in of intelligent farm to keep the best state automatically by using collected data. We believed this technology can improve industrial competitiveness through the u-IT based smart integrated management system introduction for industry aversion and dairy industries labor shortages due to hard work and old ageing.

현재 농작물의 품질과 직결되는 병해충에 관하여 농작물 재배 현장에서 바로 사용할 수 있는 모바일 전용의 응용 시스템은 부족한 실정이다. 따라서 본 논문에서는 병해충 예찰 및 기본 정보에 관해서는 충실하나 즉각적인 진단 기능이 매우 부족하고 아울러 농작물 재배 현장에서 바로 사용할 수 있는 모바일 기반의 병해충 전용 시스템의 부재를 개선하기 위해서, u-Farm을 위한 모바일 기반의 농작물 재배 현장 중심형 스마트 병해충 정보검색 시스템을 설계 및 구현한다. 제안하는 시스템은 이미지의 전문 분석에 유용한 검색 라이브러리인 루씬(Lucene) 및 JSON 데이터 구조를 기반으로 농작물 재배 현장에서 병해충의 정보를 웹뿐만 아니라, 본인이 소유한 스마트 폰을 통해 실시간으로 직접 확인할 수 있는 장점이 있다. 또한, 시스템의 확장 및 재사용성을 높이기 위해 객체지향 모델링을 기반으로 설계하였으며, 농작물의 메타 정보뿐만 아니라, 메타 정보 기반의 텍스트 및 색상 등과 같은 이미지 특징 정보를 기반으로 검색이 가능하다. 본 시스템을 통해 u-Farm 실현뿐만 아니라 농업인이나 재배 현장 관리자들이 농작물 작황, 병해충 현황 파악 및 관리를 실시간으로 진행할 수 있다.

Most of the current cultivation log is recorded by growers manually or whose environment information is input based on the grower's own judgement. It is not easy for growers to record the image of disease and insect pests in the cultivation log. In this regards, u-Farm cultivation log management system based on Web 2.0 and smart phone is introduced in this paper, that is used for the effective cultivation management and grower's convenience. In the system, the value of environment information is transmitted to servers via sensors. It designs and implements Web 2.0 Flex so as to make the cultivation log more reliable and provide users with active, convenient GUI in case the log is recorded by desktop. In this process, detailed modules are designed by object-oriented UML considering the reusability and maintenance of the system. Moreover, the system introduced in this paper is proved to be more excellent by the qualitative assessment compared with the other researches.

이코노미스트는 수산 양식업 혁명을 가리키는 블루 레볼루션을 통해 2030년경 주요 수산물 대부분이 수산 양식업을 통해 조달될 것임을 시사 했으며, William Hallal은 2015년에 양식 수산물이 전체 수산물의 50%에 이를 것으로 예측 하였다. 이러한 시대적 변화에 대응하기 위해 국내외 유관기관에서는 다양한 u-양식장에 관한 연구 및 시범사업을 수행해왔다. 본 연구는 그간 국내외 수산업 양식업 발전을 위해 수행되어 온 u-양식장 적용 사례연구를 통해 효과 및 문제점을 식별하고, ICT 기반 스마트 양식장 시스템을 위한 기술 개발 및 정책 방향을 제안하고자 한다.
