We investigated the physicochemical properties of brown rice by cultivar to select cultivar suitable for making brown rice porridge. The moisture content of the brown rice ranged from 8.79~11.78% with the highest varieties being 'Geonyangmi'. The crude ash and crude lipid content ranged from 1.02~1.65% and 1.65~3.26%, while the rest were similar except for 'Daebo'. Crude protein also had the lowest 'Daebo' and generally glutinous rice showed higher crude protein content than common rice. The hardness showed that 'Seolgaeng' and 'Keunnun' were the lowest, and 'Haiami' was the highest. In the RVA analysis, the setback was in the range -80.61~22.44 and was low in the order of 'Wolbaek', 'Baekjinju'', and 'Dongjinchal'. As a result of water binding capacity (WBC) measurement, 'Sindongjin', 'Geonyang' and 'Samkwang', were high in common rice, and 'Dongjinchal' and 'Hwaseonchal' were high in glutinous rice. Generally, solubility and swelling power in common rice was found to be lower than in glutinous rice. As a result, 'Samkwang' is considered suitable for brown rice porridge production because of high WBC, breakdown, and low setback.

2000년대 이후 화력발전소, 열병합발전소 및 소각로, 화학플랜트 등 고정 오염원의 질소산화물의 배출규제가 발효됨에 따라 대규모 배출업체를 시작으로 SCR(선택적 촉매 환원법) 탈질설비를 도입하고 있으며, 배출오염물 총량규제 등 점차적으로 배출규제가 강화되고 적용 범위가 확대됨으로 인하여 SCR 탈질촉매의 사용량이 증가하는 추세이다. 발전소나 소각장 등에 이미 설치된 SCR 탈질촉매는 2010년을 기점으로 비활성화하여 새로운 촉매로 교체됨으로써 폐촉매가 폐기물이 아닌 자원으로서 재활용하기 위한 기술개발이 절실히 필요한 상황이다. 본 연구에서는 폐촉매 재활용 기술에 대한 특허와 논문을 분석하였다. 분석범위는 1975년 ~ 2012년까지의 미국, 유럽연합, 일본, 한국의 등록/공개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였고, 기술의 정의에 의해 필터링 하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술에 따라 분석하였다. Since the 2000s, to start inducement of SCR(Selective Catalytic Reduction) denitrification facility by large scale companies which are emitted large amount of nitrogen oxides such as power plants, combined heat and power plant, incinerators and chemical plants due to take effect the regulation of stationary sources of nitrogen oxide(NOx), and the total amount of discharged pollutants, such as regulatory gradually emissions regulations are being strengthened and the expanded coverage due to the use of SCR denitrification catalyst is a growing trend. Since 2010 due to the new catalysts to replace the already installed power plants and incinerators due to inactive, and catalytic denitrification SCR waste catalyst waste as a resource rather than the development of technologies for recycling situation is urgently needed. In this study, analyzed paper and patent for recycling technologies of waste catalyst. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1975 to 2012. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies.

자연환경과 인위적 환경변화에 의한 홍수재해는 하상변동과 밀접한 관계를 갖는다. 본 연구는 금강유역을 대상으로 지리정보시스템(GIS)과 원격탐사(RS)를 이용하여 유역에서의 토양침식과 하상변동의 관계를 규명하고자 하였다. 지리정보시스템에서 범용토양유실공식 (USLE)을 이용하여 토양침식율을 계산하였다. 공주에서 이포까지 하상지형을 측량하였고, 3차원의 하상변화도를 작성하였다. 1982년에서 2000년까지 Landsat TM 영상을 이용하여 금강유역의 하상변동을 추적하였다. 연구결과, 강경일대의 토양침식율은 $1.8\;kg/m^2/$년이며, 하상증가율은 $+5\;cm/m^2/$년으로 산정되었다. 따라서 금강하류의 하상변화는 일정한 비율로 토양침식에 의하여 영향을 받는 것으로 해석된다. 또한 하상변동은 주로 금강의 지류와 본류의 접합부 하류일대에서 발생하였다. 금강하류에서 하상변동은 하성 세골재 채취가 하나의 원인으로 해석될 수 있으며, 골재채취로 인하여 1991년도에서 1995년도 사이 금강하상 위에 노출된 하상면적의 감소를 초래했던 것으로 추정된다. 한편, 금강유역 하상을 따라 교량건설, 경작지 조성을 위한 사주개간, 제방과 같은 수중 구조물들 설치는 퇴적물 집적과 퇴적하상의 노출면적 증가를 초래하였던 것으로 추정된다. Flooding hazard caused by natural and artificial environmental changes is closely associated with change in river bed configuration. This study is aimed at explaining a river-bed change related to soil erosion in the Keum river basin using GIS and RS. The USLE was used to compute soil erosion rate on the basis of GIS. River-bed profiles stretching from Kongju to Ippo were measured to construct a 3D-geomorphological map. The river-bed change was also detected by remote sensing images using Landsat TM during the period of 1982 to 2000 for the Keum river. The result shows that USLE indicates a mean soil erosion rate of $1.8\;kg/m^2/year$, and a net increase of a river-bed change at a rate of $+5\;cm/m^2$/year in the Kangkyeong area. The change in river-bed is interpreted to have been caused by soil erosion in the downstream of the Keum river basin. In addition river-bed change mainly occurred on the downstream of the confluence where tributaries and the main channel meet. Other possible river-bed change is caused by a removal of fluvial sand aggregates, which might have resulted in a net decrease of exposed area of sediment distribution between 1991 and 1995, while a construction of underwater structures, including a bridge, a reclamation of sand bars for rice fields and dikes, resulted in an increase of the exposed area of river-bed due to sediment accumulation.

Based on the Zigbee-based wireless sensor network, I suggest the way to reduce errors between the short distance, improving the accuracy of the presumed distance by revising the deviation of RSSI(Received Signal Strength Indication) values is to estimate the distance using only the RF signal power without the additional hardware. In general, the graph measured by RSSI values shows the proximity values which are ideally reduced in proportion to the distance under the free outdoor space in which LOS(Line-Of-Sight) is guaranteed. However, if the result of the received RSSI values are each substituted to the formula, it can produce a larger margin of error and less accurate measurement since it is based upon the premise that this free space is not affected by reflected waves or obstacles caused by the ground and electronic jamming engendered by the environment. Therefore, the purpose of this study is to reduce the margin of errors between the distances and to measure the proximity values with the ideal type of graph by suggesting the way to revise the received RSSI values in the light of these reflected waves or obstacles and the electronic jamming. In conclusion, this study proves that errors are reduced by comparing the proposed deviation correction method to the revised RSSI value.

We experienced a patient in whom rupture of the peroneus longus tendon occurred after ostectomy of the peroneus tubercle of the calcaneus. Acute rupture of the peroneus tendon can be managed by end-to-end anastomosis, while neglected cases can be treated by tenodesis, tendon transfer, or tendon graft. In the current patient, the tendon ends were mildly retracted, yielding a small gap. We successfully repaired the retracted tendon ends after lengthening by Z-plasty.

네트워크 인프라의 성장과 디지털 영상압축 기술의 발달로 네트워크 카메라 서버를 이용한 실시간 영상감시 시스템의 수요가 증가함에 따라 가정이나 소규모 사무실에 적합한 실용화 수준의 보안 시스템에 대한 요구도 함께 증대되고 있다. 기존의 CCTV를 이용한 실시간 영상감시에 비해 네트워크 카메라 서버를 이용한 영상감시는 많은 이점이 있다. 본 논문에선 실시간 영상감시 시스템의 핵심 모듈로서 JPEG 영상의 수집과 전달을 담당하는 JPEG Streamer의 모델을 설계, 구현하며 JPEG Streamer의 안정성과 효율성을 위해서 쓰레드 풀과 공유메모리를 사용하고 실시간 영상의 품질을 높이기 위해서 더블버퍼링의 개념도 도입하였다. 또한 제시된 Streamer의 모델을 이용하여 개인 휴대단말기(PDA)로 무선 인터넷을 통해 실시간 영상을 전송하는 무선 영상 감시시스템을 제시한다. Recently, the network Infrastructure grows rapidly and the digital image compression technique has made remarkable progress. Therefore, the demand of the real-time image surveillance system which uses a network camera server has been increasing. Network Camera Server has emerged as an attractive alternative to the CCTV for the wireless video surveillance. In this article, the model of JPEG Streamer for collecting and delivering JPEG image is designed and realized as a key module for the wireless video surveillance system. The thread pool and shared memory have been used to improve the stability and efficiency of the JPEG Streamer. In addition, the concept of double buffering is of much benefit to improve the quality of real-time image. In this article, the wireless video surveillance system by using JPEG Streamer is suggested to send the real-time image through the wireless internet with the personal digital assistance (PDA).
