<P>Ethanolamine is important for synthesis of choline, phosphatidylethanolamine (PE) and phosphatidylcholine (PC) in plants. The latter two phospholipids are the major phospholipids in eukaryotic membranes. In plants, ethanolamine is mainly synthesized directly from serine by serine decarboxylase. Serine decarboxylase is unique to plants and was previously shown to have highly specific activity to <SMALL>L</SMALL>-serine. While serine decarboxylase was biochemically characterized, its functions and importance in plants were not biologically elucidated due to the lack of serine decarboxylase mutants. Here we characterized an <I>Arabidopsis</I> mutant defective in serine decarboxylase, named <I>atsdc-1</I> (<I><U>A</U>rabidopsis <U>t</U>haliana <U>s</U>erine <U>d</U>e<U>c</U>arboxylase-1</I>). The <I>atsdc-1</I> mutants showed necrotic lesions in leaves, multiple inflorescences, sterility in flower, and early flowering in short day conditions. These defects were rescued by ethanolamine application to <I>atsdc-1</I>, suggesting the roles of ethanolamine as well as serine decarboxylase in plant development. In addition, molecular analysis of serine decarboxylase suggests that <I>Arabidopsis</I> serine decarboxylase is cytosol-localized and expressed in all tissue.</P>

Metcalfa pruinosa has been spreading in Korea since 2005, which its first report at Gimhae in Kyeongnam province. It has been harmful to grape and major forest crops by direct sucking and indirect transmitting sooty mold disease causing economical loss. It is necessary to study its tracing route and movement conditions for the further efficient population management and prevention of its re-invasion. A total of 23 haplotype were observed in the analysis of nucleotide polymorphisms on mitochondrial cytochrome c oxidase I from total 124 voucher specimens among five countries. Only two haplotypes were exist in Korea and HAP1 was accorded with its of some European individuals. Moreover, the analysis of FST and AMOVA, the Korean population was relatively nearer with Spanish and Italian population than American populations, suggesting the Korean population might be originated from some European countries. Eight microsatellite loci were developed and characterized to facilitate more delegate population genetic analysis from 468 individual in five countries. The average character of each or overall population was revealed 18 average individual number, six alleles and 0.676 heterozygosity. The genetic distance (FST) was a little bit high among each populations ranged as – 0.010~0.245. In the tracing route analysis, the originating country of Korean population was also shown as migrated from some European countries. The population genetic analysis using genetic markers will be useful to trace the origin of pest and prevent from re-invasion fro efficient pest management.

본 논문에서는 물류창고의 자연배연을 위하여 한⋅일의 법령과 일본의 설계지침에서 제공되는 설계법을 조사하고 이를 통해 수용품 특성, 건축물 특성에 따른 배연설비 유효면적을 산정하였다. 그 결과, 양국의 법적 기준을 통한 유효면적은 10 m2, 20 m2로 산정되었고, 일본 지침을 통한 결과는 7~16 m의 층고에서 CUP를 수용한 공간은 24.71 m2부터 13.76 m2, CEP를 수용한 공간은 41.83 m2부터 22.54 m2로 산정되었다. 이렇게 산정된 유효면적을 통해 배출되는 배연량의 경우, 국내 법적기준을 적용한 경우는 모든 Case에서 플륨유량보다 배연량이 적었다. 일본 기준을 적용한 경우는 CUP 적재창고에서는 9 m부터 16 m까지는 연기발생량보다 배연량이 많은 배연효율을 냈으나 7 m부터 8 m에서는 배연량이 더 적었다. 지침을 적용한 유효면적에서는 모든 Case에서 연기배출량이 연기발생량보다 많았다. This study investigated the design methodologies outlined in Korean and Japanese legislation, along with Japanese design guidelines, pertaining to natural smoke ventilation systems in logistics warehouses. Subsequently, we determined the effective area of the smoke exhaust system based on the combustible materials and building characteristics. Our findings indicated that the calculated effective area per the statutory standards of both nations was 10 m2 and 20 m2, respectively. According to Japanese guidelines, the space accommodating the CUP ranged from 24.71 m2 to 13.76 m2 for floor heights between 7 to 16 m, while the space accommodating CEP ranged from 41.83 m2 to 22.54 m2. Analyzing the quantity of smoke emitted through the calculated effective area, we observed that, when applying domestic legal standards, the smoke exhaust rate consistently remained lower than the plume flow rate. Conversely, under the Japanese standard, the smoke emission efficiency of the CUP loading warehouse surpassed that of smoke emission from 9 m to 16 m, while it was lower from 7 m to 8 m. Notably, the smoke exhaust rate consistently exceeded the generated smoke quantity in all instances within the effective area governed by the guidelines.

As buildings in South Korea become more skyscrapers, the risk of fire is also emerging. Thus, regulations, regulations, and guidelines are being improved to prevent the spread of smoke in the event of a fire in high-rise buildings, but research on smoke flow and pressure distribution in vertical spaces is insufficient. Therefore, in this study, the temperature of each floor in the vertical space according to the size of the fire is measured through the miniature model experiment, and the pressure difference is calculated to establish the basic data for the improvement of the performance of domestic air supply facilities in the future. Thus, a scale model of one-sixth the size of the actual building was produced to measure the temperature, and the pressure difference was derived by substituting the value for the expression. The pressure difference varies depending on the size of the cause of the fire, and it is believed that the differential pressure and conditions of the building should be taken into account before calculating the supply volume for the analysis of the pressure difference according to the size of the cause of the fire in the event of fire.

필로티 구조를 가진 도시형 생활주택은 건축 규제의 완화로 인해 화재위험성이 높은 실정이다. 또한;기존 화재사례 조사 결과 최초 착화지점에서 발생한 화재가 가연성 천장재를 통해 외장재로 확대되는 경로를 보였기 때문에 천장재의 화재확대방지가 우선적으로 이뤄질 필요가 있다. 이에 필로티 구조물의 천장재에 대한 조사를 시행한 결과 SMC;알루미늄;DMC;석고보드 등이 주로 사용되는 것으로 확인되었으나 70% 이상이 SMC 천장재인 것으로 조사되었다. 조사된 천장재를 대상으로 Cone Calorimeter 시험을 진행한 결과 SMC 217.10 kW/m2;알루미늄 15.07 kW/m2;DMC 1.78 kW/m2;석고보드 41.92 kW/m2로 조사되었다 Urban living spaces with piloti structures are at high risk for deregulation of building protocols. Recent fire case investigation results have shown the path of the fire from the initial ignition point to the exterior material via combustible ceiling materials; thus;preventing the spread of the fire through the ceiling material is a priority. Accordingly;investigations were conducted on the ceiling materials used in piloti structures;and it was confirmed that SMC;aluminum;DMC;and gypsum board were the main components;with the SMC ceiling materials accounting for more than 70% of the composition. Cone calorimeter tests were performed on these ceiling materials;and the heat fluxes of SMC;aluminum;DMC;and gypsum board were determined to be 217.10;15.07;1.78;and 41.92 kW/m2;respectively.

<P>Nonalcoholic fatty liver disease is a complex disorder which includes simple steatosis, steatohepatitis, fibrosis and ultimately cirrhosis. Previous studies have reported that genistein, a soy phytoestrogen, attenuates steatohepatitis induced in obese and type 2 diabetic models. Here we investigated the effect of dietary genistein supplementation (0.05%) on nonalcoholic steatohepatitis (NASH) development induced by a methionine-choline-deficient (MCD) diet in db/db mice. MCD-diet-fed mice exhibited a significantly lower body weight and a higher degree of steatohepatitis with increased oxidative stress, steatosis, inflammation, stellate cell activation, and mild fibrosis. Although genistein did not inhibit hepatic steatosis, we observed that oxidative stress, endoplasmic reticulum stress, and AMP-dependent kinase inactivation were alleviated by genistein. Genistein also down-regulated the augmented gene expressions associated with hepatic inflammation and fibrosis. Therefore, these results suggest that genistein may protect MCD-diet-mediated NASH development by suppressing lipid peroxidation, inflammation, and even liver fibrosis in db/db mice.</P>

Lycorma delicatula (White 1845), which has been recently introduced into Korea, is a notorious pest on grapes. This invasive insect has rapidly spread throughout central and southern Korea. To date, we have no behavioral or population genetics information, such as invasion routes and subsequent dispersal rates in Korea, to help understand and control populations of L. delicatula. Here, we have developed 15 novel microsatellite loci for L. delicatula. The isolated loci were polymorphic, with 2 to 19 alleles in 42 individuals from a single population in Cheonan. The analyses revealed that all 42 individuals had different multilocus genotypes with heterozygosity ranging from 0.214 to 0.866. Eleven of the 15 loci did not deviate significantly from Hardy-Weinberg equilibrium. The isolated markers will facilitate population genetic studies of L. delicatula.

반려동물을 키우는 사람들 중 1인 가구 증가로 인하여 주인의 부재 시 반려동물에게 배식하는데 어려움이 있어 자동급식기가 고안되었다. 본 논문에서는 아두이노 플랫폼을 이용한 사료 배급뿐만 아니라 약 배급 기능을 갖춘 IoT 약, 사료 혼합 자동급식기를 제안한다. 제안한 지동급식기에서는 사용자가 웹사이트를 통해 급식 서비스에 접근할 수 있고, 두 재료의 혼합 자동 배식 시스템을 통하여 편리하며 확장된 배식 기능을 경험 할 것 이라고 기대된다. Due to the increase in single-person households among the people who have companion animals, it is difficult to feed them to companion animals in the absence of the owner, so an automatic feeding machine was designed. In this paper, we propose an automatic feeding machine that has a drug distribution function as well as feeds using the Arduino platform. It is expected that in the proposed automatic feeding machine, users can access the food service through the website, and experience the convenient and extended food service function through the automatic dispensing system that combines the two materials.
