일반적으로 센서노드간의 데이타통신은 내부처리나 센싱 작업보다 더 많은 에너지 소모를 요구한다. 본 논문에서는, 내용인지(context-aware) 라우팅 테이블(routing table)을 이용하여 인접한 노드간의 질의 송수신을 위해 필요한 패킷 송신 수를 줄여 질의 최적화를 수행하는 새로운 아이디어를 제안한다. 내용인지 라우팅 테이블에는 현재 노드로부터 도달 가능한 하위노드에서 측정할 수 있는 센서의 종류에 관한 정보가 저장되어 있다. 내용인지 라우팅 정보를 이용하여 각 노드는 자식노드에게 불필요한 질의 송신이나 결과 전달을 차단함으로써 불필요한 패킷 송신의 수를 줄일 수 있다. 본 논문에서 제안한 방법을 바탕으로 한 시뮬레이션에서 최대 약 80%의 성능 효과를 보였다. In general, data communication among sensor nodes requires more energy than internal processing or sensing activities. In this paper, we propose a noble technique to reduce the number of packet transmissions necessary for sending/receiving queries/results among neighboring nodes with the help of context-aware routing tables. The important information maintained in the context-aware routing table is which physical properties can be measured by descendent nodes reachable from the current node. Based on the information, the node is able to eliminate unnecessary packet transmission by filtering out the child nodes for query dissemination or result relaying. The simulation results show that up to 80% of performance gains can be achieved with our technique.

본 연구는 proteomics의 방법을 이용하여 가금의 육질과 관련된 단백질을 찾고자 수행하였다. 인삼부산물 추출액을 급여한 실용 재래닭에서 육질과 관련된 것으로 추정되는 후보 단백질들이 선발되었으며, 이 결과는 가금의 육질을 향상시키는 단백질 Marker로서 이용될 수 있을 뿐만 아니라 현재까지 밝혀지지 않은 가금의 2D map을 만드는데 역시 중요하게 이용될 수 있다. There is growing interest for improving meat quality in chicken. Recently, the proteomics can be used as a valuable tool for identifying candidate proteins. In this study, we investigated the proteins expressed in chicken muscle for obtaining chicken muscle reference two dimensional(2D) map and identifying the proteins in muscle affecting Ginseng diet. A few candidate proteins have been currently characterizing using MALDI - TOF Mass spectrometry. Further investigations of the proteins can be used as valuable markers for selection of better quality chicken meat.

본 연구는 proteomics의 방법을 이용하여 가금의 육질과 관련된 단백질을 찾고자 수행하였다. 인삼부산물을 급이한 실용재래계와 대조구와의 비교에서 육질과 관련된 3개의 후보 단백질이 이 연구를 통해 밝혀졌다. 이 유전자들은 tropomyosin, triosephosphate isomerase와 한 개의 기능이 밝혀지지 않은 단백질이었다.<br/> 각각의 기능을 살펴볼 때 이 유전자들은 근육의 성장과 면역의 증강에 관여하며 이 결과는 인삼부산물을 이용하여 가금의 육질을 향상시키는 단백질 마커로 중요하게 이용이 될 수 있을 것으로 추정된다. The present study was aimed to investigate proteome affected by Panax ginseng extracts in chicken muscles. More than 300 protein spots were detected on silver staining gels. Among them, four protein spots were distinctively up-regulated by Panax ginseng treatments. The up-regulated proteins were finally identified as tropomyosin (2 spots), triosephosphate isomerase, and one unknown protein. Based on the known functions of the identified proteins, they are highly related to the muscle development and enhanced immunity in chicken. These proteins can give valuable information of biochemical roles for Panax ginseng in chicken meats.

공허안증후군은 뇌하수체와 내로 거미막하 공간이 내려와 뇌하수체가 편평해지는 질환이다. 공허안증후군 환자의 대부분은 뇌하수체 기능 장애 없이 우연히 발견되는 경우가 많다. 저자들은 이차 성징 발현 소실을 주소로 내원한 30세 남자에서 원발성 공허안증후군과 중추성 요붕증, 단독성 성선자극호르몬 결핍증이 동반되었음을 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Primary empty sella syndrome(PESS) associated wish trophic hormone deficiency is rare. Furthermore, PESS with central type of diabetes insipidus(DI) and isolated anterior pituitary hormone deficiency is extremely rare. We experienced a case of PESS associated with central type of DI and isolated gonadotropin deficiency in a 30-year-old man who had complained of sexual infantilism and polyuria. MRI of pituitary gland showed posteriorly displaced pituitary stalk and CSF-like signal intensity in the sella turcica. We report this case wish review of the relevant literatures.

본 연구는 proteomics의 방법을 이용하여 가금의 면역시스템에 관련된 단백질을 찾고자 수행하였다. 면역활성 물질을 처리한 후 면역활성화시 발현되는 단백질을 찾아보았다. 이 결과는 가금의 면역과 관련된 단백질 마커의 이용뿐 아니라 현재까지 밝혀지지 않은 가금의 2D map을 만드는데 역시 중요하게 이용이 될 것이다. Specific biomarkers to detect significant immunological or physiological responses would be extremely valuable on the development of feeding technique. Proteomics, the study of proteins within a cell or biological samples, may offer a novel approach to immunological or physiological monitoring of chicken responses to immune system. By studying the protein content of cells responding to a vaccine or growth factor, it may be possible to develop a metric for quantitating the magnitude of immunological or physiological responses. Proteomics could also provide a tool for obtaining valuable information regarding the underlying regulatory mechanisms and pathways in Korean Native Chicken by comparing with subspecies of KNC and other species, like Cornish and White Leghorns.

To investigate the manufacturing methods of surimi-like materials (SLM) from breast muscle of spent hen, the muscles were diced, chopped and washed with distilled water or sodium chloride solution at 0.1, 0.5 and 1% level and then washed with distilled water to extract myofibrillar protein. When used only distilled water to extract myofibrillar protein, washing was repeated 3 times followed by homogenization and centrifugation of breast muscle after each washing (CM; conventional method). Whereas, to extract myofibrillar protein using sodium chloride solution had sufficient to do 2 times washing by distilled water after 1 time washing by sodium chloride followed by homogenization and centrifugation of breast muscle after each washing (NM; new method). The both batter and cooked SLM gel from NM had significantly (p<0.05) lower redness compared with CM. Again, SDS-PAGE with sarcoplasmic protein fractions showed that the bands of phosphorylase had increased staining intensity in NM compared with CM. These results indicated that the brightness was related to sarcoplasmic protein fractions. SDS-PAGE with myofibrillar protein showed that the bands of myosin had increased staining intensity in NM compared with CM. Data implied that myofibrillar protein extraction with sodium chloride solution had the better adaptability for the breast muscle of spent hen then the commonly used distilled water method.

This experiment was conducted to investigate the effect of dietary supplementation of the Black Soldier Fly(BSF) larvae on growth performance, carcass rate, and fatty acid profile of chicken meat in broiler chicks. Four hundred eighty 1-d-old broilers(Ross 308) were distributed into 3 treatments with 4 pens at 30 birds per replicate. Treatments were corn-soybean meal based broiler diet (control) and the basal diet replaced with BSF at the level of 3 and 6% respectively. Viability was not different significantly. Body weight gain was higher in control than other treatments. Feed intake was not statistically different of treatments. Feed conversion ratio was lower in ontrol than other treatments. Relative weight of breast meat was significantly increased in all treated groups than in control. But, another relative weights of chicken meat cuts (thigh, wing, neck, back) were not significantly different among the groups. In conclusion, it could be suggested that dietary supplementation of Black Soldier Fly larvae could beneficially improved the performance on broiler
