In this paper, an intelligent control of the greenhouse in the Greenhouse Management Framework (GMF) has been designed for the purpose of increasing the farmer’s profit and promoting the ease of agricultural production. The GMF is divided into Greenhouse Control Engine and Crop Growth Engine. The Greenhouse Control Engine consists of Data Aggregator, Greenhouse Information Storage, and Greenhouse Control Agent. The Greenhouse Control Agent includes Information Analyzer, Control Device Selector, and Greenhouse Control Model. The Crop Growth Engine consists of Crop Status Information Storage and Crop Growth Agent. The Crop Growth Agent includes Crop Status Predictor, Environment Set-points Decisioner, and Crop Growth Model. In this paper, the aim to reduce the consumption cost of the control device driven for the optimal greenhouse growth environment is one of the major features of the framework that is being proposed. In order to reduce heating cost, which consists of a major part in the cost of cultivation, we have tested the performance of our proposal for the GMF through the simulation. The simulated results confirm the decrease of heating costs from the present GMF.

<P>The expansion in knowledge of the microbial community structure can play a vital role in the electrochemical features and operation of microbial fuel cells (MFCs). In this study, bacterial community composition in a dual chamber MFC fed with brewery waste was investigated for simultaneous electricity generation and azo dye degradation. A stable voltage was generated with a maximum power density of 305 and 269?mW?m(-2) for brewery waste alone (2000?mg?L(-1)) and after the azo dye (200?mg?L(-1)) addition, respectively. Azo dye degradation was confirmed by Fourier transform infrared spectroscopy (FT-IR) as peak corresponding to -N=N- (azo) bond disappeared in the dye metabolites. Microbial communities attached to the anode were analyzed by high-throughput 454 pyrosequencing of the 16S rRNA gene. Microbial community composition analysis revealed that Proteobacteria (67.3?%), Betaproteobacteria (30.8?%), and Desulfovibrio (18.3?%) were the most dominant communities at phylum, class, and genus level, respectively. Among the classified genera, Desulfovibrio most likely plays a major role in electron transfer to the anode since its outer membrane contains c-type cytochromes. At the genus level, 62.3?% of all sequences belonged to the unclassified category indicating a high level of diversity of microbial groups in MFCs fed with brewery waste and azo dye.</P>

Miran, Waheed,Rasool, Kashif,Nawaz, Mohsin,Kadam, Avinash,Shin, Seolhye,Heo, Jun,Jang, Jiseon,Sung Lee, Dae Taylor Francis 2016 Desalination and Water Treatment Vol.57 No.19

<P>Microbial fuel cells (MFCs) are gaining tremendous interests for achieving simultaneous power production and recalcitrant wastewaters treatment. In this study, simultaneous electricity generation and tetra-azo dye (Direct Red 80) decolorization was examined in a dual chamber MFC. In addition, glucose and various volatile fatty acids were separately examined as co-substrates for anaerobic dye degradation and bioelectricity generation. Maximum power of 477.8 and 455.7mW/m(2) were attained with glucose (1,000mg/L) as a sole carbon source and glucose (1,000mg/L) coupled with dye (200mg/L), respectively. At this glucose and dye initial concentration, 85.8% color and 74.9% COD removal were resulted in 48h batch studies. Color removal without any co-substrate's addition was 23%, indicating dye was degraded mainly in the presence of carbon sources. There was no substantial negative effect in electricity generation was observed with the dye degradation. Dye removal was decreased with the increase in dye initial concentration (25-800mg/L) and increases notably with the increase in initial glucose concentration between 0 and 1,000mg/L, while afterward insignificant effect up to 2,000mg/L was observed. Glucose was determined as better co-substrate followed by acetic, propionic, and lactic acid in terms of dye removal and maximum power production. Gas chromatography-mass spectrometry showed sodium 4-aminoazobenzene-4-sulfonate to be the subsequent metabolites formed during the decolorization of dye. This work demonstrated that MFC could be applied to achieve electricity generation and simultaneous azo dye degradation using glucose as the preferred co-substrate.</P>

인쇄업이란 계약 또는 수수료에 의하여 인쇄물 및 출판물을 각종 제판술로 인쇄해내는 산업 활동을 일컫는데, 산업 특징상 노동집약적인 중·소기업형 영세업종의 형태가 보편적이다. 또한, 인쇄업은 주문에 의해 생산이 진행되는 수주산업이기 때문에 소기업 간 경쟁이 매우 치열하다. 더불어 인쇄업은 높은 시장 지향성을 띄는 도시형 산업으로, 예로부터 서울로, 그중에서도 유동인구가 많고 중심업무기능이 밀집해있는 곳으로 입지하기 시작하였다. 2013년 통계청 자료를 기준으로 서울특별시 내의 인쇄업체 수는 7,997개이며, 그중 중구에 위치한 인쇄업체 수는 5,450개이다. 이로써 중구는 서울시 전체 인쇄업체의 약 68%를 차지하고 있는 인쇄업의 중심지라고 할 수 있다. 본 연구에서는 국내 유일의 인쇄업 집적지인 중구의, 그중에서도 을지로 일대의 인쇄업이 언제, 어디서부터 시작되었는지 또한 시간의 흐름에 따라 인쇄업체의 입지 이동이 어떻게 진행되어 왔는지에 대해 분석해봄으로써 중구 인쇄업 집적지의 의의를 파악하고자 한다, 중구 지역은 조선시대부터 전통적으로 인쇄업의 중심지다. 1403(태종3)년에 주자소가 설치되었고 1800년대 이후 근대 인쇄업 또한 중구 을지로 2가를 중심으로 점차 주변 지역으로 확산되었다. 이후 1980년대 도심 재개발 정책에 따라 인쇄업 일부가 서울 외곽지역으로 이전하였지만, 최근 소규모 영세업체들이 다시 중구 을지로 일대로 재입지하는 추세를 보이고 있다. 또한, 답사를 통해 연구지역인 중구의 10개 동을 잘 정돈된 골목과 하청업체가 많은 곳, 낡고 좁은 골목들로 영세업체들이 밀집된 곳, 규모가 크고 첨단화된 곳으로 3가지의 큰 특징으로 분류하였다. 이로써 중구 을지로 일대는 시대의 흐름에 발맞춰 고유의 발전을 이룩한 우리나라 최대의 인쇄업 클러스터 지역이라고 할 수 있으며, 도시형 제조업인 인쇄업의 특성상 계속해서 중구 일대에 집적지를 이룰 것이다. Printing Business is called an industry activity that printing publication and printed matter by contract or commission. By the industry characteristic of printing business, it is universal pretty type of industry that labor-intensive of small business. Because printing business is an order made production industry, the competitions of a small-scale enterprises are very intensive. In addition, printing business is a city type industry that market oriented, so printing business has been concentrated in Seoul, that has many floating population and concentrated main function from old times. By the data of National Statics Office in 2013, there are 5,450 printing enterprises in Jung-gu and printing enterprises in Seoul are 7,997. So Jung-gu is a center of printing business that located 68% of printing enterprises. In this study, we look forward to know about Jung-gu that domestic unique printing cluster"s meaning by analysis when started cluster the whole region of Eulji-ro and moved location process as times goes by. Jung-gu has been traditional center of printing business from the Joseon period. When king Taejong period, in 1403 the typefoundry was set up and after 1800s printing business was spread out by the Eulji-ro-2-ga, Jung-gu. Since 1980s, some of the printing business enterprises relocated in outside of seoul by the urban redevelopment policy. But recently, small-scale enterprises are tend to relocate in Eulji-ro, Jung-gu area. Also, we classify 10 dong in Jung-gu into 3 groups by the big characteristics- At First, well arranged alleys and a lot of subcontractors, Second, concentrated small-scale enterprises in old and narrow allays and Third, big scale and modern region. So Eulji-ro, Jung-gu is one of the biggest printing clusters in Republic of Korea that indigenous development industry as times goes by. And printing cluster will stay in Jung-gu area by the characteristic of urban manufacturing.

식물공장은 센서네트워크를 비롯한 U-IT 기술이 접목된 미래 농업기술 중 하나로서 기존 온실재배 기술의 한계인 외부 환경적 요인의 영향을 최소화 할 수 있는 장점을 갖고 있다. 식물공장의 자동화된 재배 시스템은 작물 재배에 대한 편의 제공이라는 단순한 범위을 벗어나 식물공장에서 취득된 정보을 기반으로 하는 지식베이스의 구축과 이를 활용한 교육, 기타 응용 서비스 개발이 가능한 플랫폼으로서의 확장성을 제공한다. 본 논문에서는 식물공장의 서비스 확장을 위하여 식물공장 간 작물생육과 연관된 정보의 효율적 공유를 위한 Plant Factory Interworking Service(PFIS) 를 설계하고 이에 대한 구현 및 서비스 테스트에 대한 연구를 수행하였다. The plant factory represents one of the future agricultural systems into which ubiquitous information technology (U-IT) is incorporated, including sensor networking, and helps minimize the influence of external experimental factors that constrain the use of existing greenhouse cultivation techniques. A plant factory’s automated cultivation system does not merely provide convenience for crop cultivation, but also expandability as a platform that helps build a knowledge database based on its acquired information and develop education and other application services using the database. For the expansion of plant factory services, this study designed a plant factory interworking service (PFIS) which allows plant factories to share crop growth-related information efficiently among them and performed a test on the service and its implementation.
