한국건축시공학회 한국건축시공학회지 2010, Vol.10 No.6 1-6 (6 pages)
건축물의 총 소유비용을 분석하기 위해서는 초기단계의 설계와 시공비용 이외에도 기획비용, 유지관리 및 운영비용을 고려해야 한다. 이를 LCC(Life Cycle Cost)라고 부른다. 현재, 충분한 데이터와 기준의 부족으로 인해 LCC의 분석에 많은 어려움을 겪고 있다. 본 연구에서는 건축물의 LCC 분석 방법을 제시하고, 현대식 아파트와 전통 한옥 주택에 대한 LCC 사례 분석을 수행하고자 한다. 사례 연구의 결과 한옥이 현대식 아파트에 비해 유지보수와 운영 비용에 있어서 보다 효율적인 것으로 조사되었다. -

have many problems particularly with software cost estimation and the assessment of the evaluation model. Software cost estimation mainly depends on two factors which are the estimation consistency and estimation accuracy. These are very much important to the perfect development of the software without any drawbacks to it. In the past there have been many models and techniques that have failed to give the correct software estimation that really challenges the all factors of perfect software in... -

pond to 8,888 $/yr infiltration system. The highest LCC were observed in constructed wetland ($418,324) while vegetated system had the lowest LCC ($210,418). LCC of BMPs was not so high as compared with the conventional treatment facility and sewage treatment plant. On the other hand, the relationship of removal efficiency on unit cost for TSS and TN was significant. This study will be used to design the cost effective BMP for diffuse pollution management and become models for LCC analysis. -

한국교육사회학회 교육사회학연구 2014, 제 24권 제 3호 1 1-29 (29 pages)
그 동안 취약계층 자녀를 위한 조기교육에 대한 투자의 중요성을 인정하면서도 그 보상교 육의 효과에 대해서는 회의적인 생각이 지배적이었다. 그렇지만 인지 능력보다는 정의적 능 력에서 변화를 통한 조기 유아교육의 유의미한 효과를 보여주는 일련의 연구결과는 빈곤에 대한 보상교육이 학업성적 향상과 이를 바탕으로 한 높은 사회경제적 지위 성취를 가정한 종전의 기본이념에 대한 전환점을 제기하고 있다. 또한, 사회형평성 차원에서만 고려되던 취 약계층에 대한 조기교육 프로그램은 장래에 발생할 수 있는 사회적 비용을 줄일... -

Rice blast disease, caused by Magnaporthe oryzae, results in an extensive loss of rice productivity. Previously, we identified a novel M. oryzae secreted protein, termed MSP1 which causes cell death and pathogen-associated molecular pattern (PAMP)-triggered immune (PTI) responses in rice. Here, we report the transcriptome profile of MSP1-induced response in rice, which led to the identification of 21,619 genes, among which 4,386 showed significant changes (P < 0.05 and fold change > 2 or < 1/2)... -

bp. Sites within the aligned sequences were conserved (53%), parsimony-informative (17%), singletons (28%), and indels (2%), respectively. Neighbor-Joining analysis showed intra and inter-nematodal variations within the populations as clone sequences from different nematodes irrespective of the sex of nematode isolate clustered together. Morphologically, the three groups (I, II and III) could not be distinctly associated with the molecular data from the 18S rRNA sequences. The three groups may... -

Betulinic acid (BA), a pentacyclic lupane-type triterpene, has a wide range of bioactivities. The main objective of this work was to evaluate the hepatoprotective activity of BA and the potential mechanism underlying the ability of this compound to prevent liver damage induced by alcohol in vivo. Mice were given oral doses of BA (0.25, 0.5, and 1.0 mg/kg) daily for 14 days, and induced liver injury by feeding 50% alcohol orally at the dosage of 10 ml/kg after 1 h last administration of BA. BA... -

JieWang, LiZhang, LijuanWang, ZhonghongLiu, YuYu 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.1 6 45-54 (10 pages)
Our study aims to determine the metabolism and excretion of novel pulmonary-targeting docetaxel liposome (DTX-LP) using the in vitro and in vivo animal experimental models. The metabolism and excretion of DTX-LP and intravenous DTX (DTX-IN) in New Zealand rabbits were determined with ultra-performance liquid chromatography tandem mass spectrometry. We found DTX-LP and DTX-IN were similarly degraded in vitro by liver homogenates and microsomes, but not metabolized by lung homogenates.... -

Berenice Nyland, Yang Gao, Zeng Xioadong, Josephine Ng 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 26 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2016, Vol.10 No.3 4 71-96 (26 pages)
In recent years early childhood education has become a focus for ambitious reforms in China. The emphasis on early experiences in this study was designed to address issues of unequal life chances, that is, the opportunities that individuals have to improve their lives across the life span. Children in rural China are more likely to be educationally disadvantaged and lack of birth registration compounds this problem. This paper examines data from rural China that was designed to collect household... -

due to its low cost and easy preparation. To find the optimum urea content, we tested three different ratios of urea to graphene oxide. The morphology of the composites was examined by field emission scanning electron microscope. Functional groups and bonding characterization were measured by X-ray photoelectron spectroscopy. Electrochemical properties were characterized by cyclic voltammetry in an organic electrolyte solution. Compared with thermally reduced graphene/sulfur (S) composite,... -

The cross sectional area (CSAs) of the RF and muscle thickness of the TA and GMM were measured at... -
Regulation of Pathogenesis by Light in Cercospora zeae-maydis: An Updated Perspective
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 2호 1 103-109 (7 pages)
The fungal genus Cercospora is one of the most ubiquitous groups of plant pathogenic fungi, and gray leaf spot caused by C. zeae-maydis is one of the most widespread and damaging foliar diseases of maize in the world. While light has been implicated as a critical environmental regulator of pathogenesis in C. zeae-maydis, the relationship between light and the development of disease is not fully understood. Recent discoveries have provided new insights into how light influences pathogenesis and... -

대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 3호 8 399-407 (9 pages)
A recombinant replication-defective adenovirus expressing the major epitopes of porcine circovirus-2 (PCV-2) capsid protein (rAd/Cap/518) was previously constructed and shown to induce mucosal immunity in mice following intranasal delivery. In the present study, immune responses induced by intranasal immunization with a combination of rAd/Cap/518 and cytosine-phosphate-guanosine oligodeoxynucleotides (CpG ODN) were evaluated in mice. The levels of PCV-2-specific IgG in serum and IgA in saliva,... -
An overview of calf diarrhea - infectious etiology, diagnosis, and intervention
Yong-il Cho, Kyoung-Jin Yoon* 대한수의학회 Journal of Veterinary Science 17 Pages
대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 1호 1 1-17 (17 pages)
Calf diarrhea is a commonly reported disease in young animals, and still a major cause of productivity and economic loss to cattle producers worldwide. In the report of the 2007 National Animal Health Monitoring System for U.S. dairy, half of the deaths among unweaned calves was attributed to diarrhea. Multiple pathogens are known or postulated to cause or contribute to calf diarrhea development. Other factors including both the environment and management practices influence disease severity or... -
Development of a real-time SYBR Green PCR assay for the rapid detection of Dermatophilus congolensis
Alfredo García, Remigio Martínez, José Manuel Benitez-Medina, David Risco, Waldo Luis García, Joaqu& 대한수의학회 Journal of Veterinary Science 4 Pages
대한수의학회 Journal of Veterinary Science 2013, 제 14권 제 4호 17 491-494 (4 pages)
Methods such as real time (RT)-PCR have not been developed for the rapid detection and diagnosis of Dermatophilus(D.)congolensis infection. In the present study, a D. congolensis-specific SYBR Green RT-PCR assay was evaluated. The detection limit of the RT-PCR assay was 1 pg of DNA per PCR reaction. No cross-reaction with nucleic acids extracted from Pseudomonas aeruginosa, Mycobacterium tuberculosis, Staphylococcus aureus, or Austwickia chelonae was observed. Finally, the RT-PCR assay was used... -

(PES) were implanted in male Sprague-Dawley rats (BW 400 ± 20 g). Two and four weeks after stent implantation, the aorta were collected, fixed with 2% glutaraldehyde, and cut into two segments. One segment was used for scanning electron microscopy analysis to evaluate re-endothelialization, and the other segment was used to calculate the neointimal area. At 2 weeks after stenting, the appearance of neointimal hyperplasia was less in the PES group than in the BMS group. At 4 weeks after stentin...
