The system designed in this paper, can mark the interior state of greenhouse using sensors of temperature, humidity and illumination on greenhouse interior by greenhouse system for farm village area's agriculture automation. And, the real time monitor is possible real time monitoring by camera. Also, system that can supply water using spring cooler system and humidifier. The proposed system can sustain a designed environment of the greenhouse through rentilation fan, fluorescent light and roof door control. TCP/IP is used for the remote control of state the sensors in the client program. 본 논문에서 설계된 시스템은 농촌 지역의 농업 자동화를 위한 온실 시스템으로 온실 내부에 온도, 습도, 조도 센서를 이용한 온실 내부의 상태를 표시할 수 있으며 카메라를 이용하여 실시간 관측이 가능하다. 또한 본 시스템은 지붕 개폐, 스프링 쿨러와 가습기를 이용한 수분 공급, 환풍기, 형광등 등을 통하여 온실 내부의 환경을 유지시킬 수 있다. 모든 센서를 이용한 상태와 온실 제어를 TCP/IP를 이용한 클라이언트 프로그램에서 원격으로 관리할 수 있다.

Korea is rapidly aging to make the fastest pace even when compared to the advanced countries of the world, and entered into an aging society in 2017. The current classification of welfare facilities for the elderly is divided into medical facilities, home welfare facilities, and leisure facilities, but the elderly who enter the facility are similar to the disease, functional status and health problems and requirements. However, due to institutional problems and entrance criteria, the facilities are still classified separately, so that they can not meet the needs of the consumer through the troublesome procedure when moving between hospitals and welfare facilities. This demanding regulation naturally causes the burden of supporting the family have. Welfare facilities are important for families who need economic activity and elderly people who have difficulty living alone. Elderly people who are in need of returning home after surgery because of health problems or sudden accident rate while using care service For our part, our old age system is not right. The purpose of this study is to propose the improvement plan for the urgent care for the elderly in Korea based on the comprehensive contents after analyzing the case of the elderly medical welfare system for the elderly and analyzing the space according to the facility.

Purpose Rhei Rhizoma (RR) is one of the herbal medicines traditionally used to treat diverse inflammatory diseases. The present study was undertaken to elucidate the antioxidant and anti-inflammatory activities of Rhei Rhizoma on experimental reflux esophagitis (RE) in rats. Methods The antioxidant activity of RR in vitro was measured in terms of radical scavenging capacity such as DPPH and ABTS. RE was produced by ligating both the pylorus and the transitional junction between the forestomach and the corpus. Rhei Rhizoma (125 and 250 mg/kg) were administered every day for 7 days, and its effect was estimated on comparison with RE control and normal rats. Results RR scavenged DPPH and ABTS effectively and IC50ofDPPH and ABTS radical scavenging activity of RR were 4.8 μg/ml and 15.75 μg/ml. The administration of RR decreased the elevated serum ROS in RE control rats. The RE control rats exhibited the down-regulation of antioxidant-related proteins such as Nrf2 and HO-1expression levels in the esophagitis; however, the level in the RR-treated RE rats was significantly higher than that in the RE control rats. Moreover, RE control rats exhibited the up-regulation of the protein expression related to oxidative stress at the esophagitis, but RR administration significantly reduced the expression of inflammatory proteins through the MAPK-independent signaling pathways. The expression of inflammatory mediators and cytokines by NF-κB activation was modulated through blocking the degradation of IκBα. In addition, the oral administration of RR regulated the gastric mucosal damage in RE rats. Conclusion The administration of Rhei Rhizoma effectively ameliorates the inflammatory damage of esophageal mucosa through radical scavenging activity and the activation of the Nrf2/HO-1 pathway.

A β-glucosidase from Penicillium italicum was purified with a specific activity of 61.8 U/mg, using a chromatography system. The native form of the enzyme was an 88.5-kDa tetramer with a molecular mass of 354 kDa. Optimum activity was observed at pH 4.5 and 60oC, and the half-lives were 1,737, 330, 34, and 1 hr at 50, 55, 60, and 65oC, respectively. Its activity was inhibited by 47% by 5 mM Ni2+. The enzyme exhibited hydrolytic activity for p-nitrophenyl-β-D-glucopyranoside (pNP-Glu), p-nitrophenyl-β-D-cellobioside, p-nitrophenyl-β-D-xyloside, and cellobiose, however, no activity was observed for p-nitrophenyl- β-D-lactopyranoside, p-nitrophenyl-β-D-galactopyranoside, carboxymetyl cellulose, xylan, and cellulose, indicating that the enzyme was a β-glucosidase. The kcat/Km (s-1 mM-1) values for pNP-Glu and cellobiose were 15,770.4 mM and 6,361.4 mM, respectively. These values were the highest reported for β-glucosidases. Non-competitive inhibition of the enzyme by both glucose (Ki = 8.9 mM) and glucono-δ-lactone (Ki = 11.3 mM) was observed when pNP-Glu was used as the substrate. This is the first report of non-competitive inhibition of β-glucosidase by glucose and glucono-δ-lactone.
