In this paper, we develop noninformative priors for the log-normal distributions when the parameter of interest is the common mean. We developed Jeffreys' prior, th reference priors and the first order matching priors. It turns out that the reference prior and Jeffreys' prior do not satisfy a first order matching criterion, and Jeffreys' pri the reference prior and the first order matching prior are different. Some simulation study is performed and a real example is given.

The purpose of this paper is to prove some common fixed point theorems for finite number of discontinuous, noncompatible mappings on non complete Menger spaces. Our results extend, improve and generalize several known results in Menger spaces. We give formulas for total number of commutativity conditions for finite number of mappings.

In this paper we obtain a unique common fixed point theorem for four self-maps which are involved in (𝜙, 𝜓)-weak contraction of a partially ordered b-metric space. The necessary condition has been given to a space for the existence of an unique common fixed of the maps. And our work changed conditions and nonlinear contraction, and search for the unique common fixed point of the maps.

Integrating various pathway data collections to create new biological knowledge is a challenge, for which novel computational tools play a key role. For this purpose, we developed the Java-based conversion modules KGML2SBML and KGML2BioPAX to translate KGML (KEGG Markup Language) into a couple of common data exchange formats: SBML (Systems Biology Markup Language) and BioPAX (Biological Pathway Exchange). We hope that our work will be beneficial for other Java developers when they extend their bioinformatics system into SBML- or BioPAX-aware analysis tools. This is part of our ongoing effort to develop an ultimate KEGG-based pathway enrichment analysis system.

Effect of Quartz porphyty(QP) on functional and morphological changes of the liver and kidney was studied in male common finch and white java sparrow fed with the basal diet(Control group) or experimental diet containing 3.0% QP(QP group) for 14 days. There was not significantly different morphological change of the liver upon light microscopic examination in common finch and white java sparrow between control group and QP group. Morphological change of renal tissue upon light microscopic examination in common finch and white java sparrow was not also significantly different between control group and QP group. The concentrations of serum creatinine, blood urea nitrogen, and nric acid as renal functional parameters of common finch and white java sparrow were not significantly different in the both groups. The activity of glutamic oxaloacetic transaminase(GOT) as hepatic functional parameter in common finch was significantly higher in the QP group($\rho$<0.05), whereas the activity of glutamic pyruvic transaminase(GPT) as hepatic functional parameter in common finch was not significantly different in the both groups. The activities of GOP and GPT in white java sparrow were not significantly different in the both groups. The morphologic findings and functional parameters of the liver and kidney observed in common finch and white java sparrow fed with 3.0% QP diet showed evidence of slightly liver damage accompanied with increased release of enzyme and fatty change of the hepatocytes in common finch, suggested that the tissues in some animals can be damaged by feeding a diet supplemented with 3.0% QP.

이 연구의 목적은 오래전부터 인정되어온 산하주민(山下主民)들의 관습적인 산림이용권이 일제하 산림소유권의 재편과정을 겪으면서 어떻게 처리되었는가를 밝히는 데 있다. "어느 지역의 주민이 집합체의 관계로 촌락공유림(村落共有林)이나 타인의 토지에서 초목, 야생물 및 토사의 채취, 방목 기타의 수익을 하는 권리"로 정의할 수 있는 관습적인 산림이용권은 총유(總有)와 특수지역권(特殊地役權)으로 구분할 수 있으며, 그러한 권리가 적용되는 산림을 촌락공유림(村落共有林) 및 특수지역림(特殊地役林)으로 구분할 수 있다. 이러한 관습적인 산림이용권은 삼림법(森林法)(1908), 삼림령(森林令)(1911), 조선임야조사사업(朝鮮林野調査事業)(1917~1924) 및 조선특별연고삼림양여사업(朝鮮特別緣故森林讓與事業)(1926~1934)을 거치면서 그 권리가 사유(私有) 또는 공유(公有)로 전환 해체되었다. 특히, 조선특별연고삼림양여사업(朝鮮特別緣故森林讓與事業)의 결과 관습적인 산림이용권은 소유권과 이용행태의 측면에서 큰 변화를 초래했다. 즉, 소유권이 공유(共有)(연고(緣故) 포함)에서 사유(私有) 또는 공유(公有)로 전환되었고 관습적인 산림이용권의 핵심내용인 집합체로서의 공장이용권이 해체된 것이다.

Vocalizations of the common dolphin Delphinus Delphis, were recorded from a single hydrophone while coastal visual survey was performed in the East Sea in March 2017. Like most Delphinidae, common dolphins produce whistles, echolocation clicks, and burst-pulsed calls, with repertoires that differ between species and geographically separated populations. This study focuses on using frequency analysis to classify sounds into three categories and to compare them with those of other common dolphin populations. The fundamental frequencies of the whistles were high in the 6 to 14 kHz range, while echolocation clicks were in the 40 to 90 kHz frequency band. These results are similar to high-energy distributions in the same frequency band in other regions. Based on this study of the acoustic characteristics of dolphins off the east coast of Korea, cetacean vocalizations can be classified using a database of cetacean sounds in Korea. In addition, this technique could improve data quality for visual whale surveys and could be applied to various other research subjects.

The disease-causing koi herpes virus (KHV), also known as cyprinid herpesvirus-3 (CyHV3), causes mass mortality of koi and carp. Koi (Cyprinus carpio) is a host for KHV, one of 12 virus species in the Alloherpesviridae family. We examined the effects of KHV disease koi (KK), and on koi×red common carp (KR) and red common carp×koi (RK) cross, using a virus challenge test. The infected fish had clinical signs that included gill necrosis and skin lesions. The RK and KR were highly more resistant (cumulative mortality: RK; 6% and KR; 8%) to KHV infection than KK fish (cumulative mortality: 28%). KHV DNA was confirmed in the tissues of all dead fish in groups by use of polymerase chain reaction (PCR), and the presence of the KHV protein in kidney was confirmed by immunohistochemistry. Histological analysis showed severe gill lesions and fusion of the lamellae in KK fish, but less severe damage in RK fish. In immunohistochemistry analysis, the KHV protein localized in the cytoplasm of infected kidney cells of KK, but the cross groups had lower levels of KHV antigen. Our data indicate that the cross groups had increased resistance to KHV disease.

본 시험은 2010년부터 2012년까지 경북 성주에서 2모작 작부체계에 알맞은 다수성이며 조숙성인 콤먼베치의 품종을 선발 할 목적으로 헤어리베치 Cold green, 콤먼베치 Maxivesa, Wild common, Rasina, Morava 및 Blanchefleur의 생육특성, 건물수량 및 사초품질을 평가하였다. 시험설계는 품종을 처리로한 6처리 3반복의 난괴법으로 배치하였다. 파종은 2010년 10월 11일과 2011년 10월 3일에 하였으며 수확은 2011년 5월 4일과 2012년 5월 10일에 실시하였다. 가을의 초형은 Wild common은 부복형이었으며 다른 품종들은 반직립형이었다. 유식물의 활력은 다른 품종들에 비해 Wild common이 다소 낮았다. 내한성은 Cold green과 Wild common이 우수했으나 다른 콤먼베치 품종들은 낮았다. 개화기는 Cold green이 4월 22일로 가장 빨랐으며 Wild common은 4월 26일 Rasina와 Blanchefleur가 4월 28일이었으며 Maxivesa가 5월 17일이었다. 1년차 시험에서 건물수량은 Cold green은 다른 5품종보다 수량이 높았으며 (p<0.05), Wild common은 나머지 4품종보다 많았으며 (p<0.05), Maxivesa와 Blanchefleur는 Rasina와 Morava보다 높았다 (p<0.05). 2년차 시험에서도 건물수량은 Cold green은 다른 5품종 보다 높았으며 (p<0.05), Wild common은 다른 4품종보다 높았다 (p<0.05). 일반적으로 베치의 CP 함량은 높았고 섬유소함량은 낮았다. 가을 파종 콤먼베치의 품종은 개화기가 빠르며 내한성이 강한 Wild common이 좋을 것으로 생각된다.

In this paper we prove common fixed point theorem for four mappings, under the condition of compatible mappings of type ($\alpha$) in Menger space, without taking any function continuous. We improve results of Pathak, Kang and Baek [13] and Cho, Murthy and Stojakovic [37].
