We enzymatically modified rice starch to produce highly branched amylopectin and amylose analyzed the resulting structural changes. To prepare cluster (HBAPC), we first treated waxy with Thermus scotoductus α-glucanotransferase (TSαGT), followed by treatment Bacillus stearothermophilus maltogenic amylase (BSMA). Highly (HBA) was prepared incubating subtilis 168 branching enzyme (BBE) subsequently treating it BSMA. The molecular weight of TSαGT-treated reduced from 8.9 × 10 8 1.2 5 Da,...

Maltogenic amylase and α-glucanotransferase (α-GTase) were employed in an effort to develop efficient process for the production of isomaltooligosaccharides (IMOs). Bacillus stearothermophilus maltogenic (BSMA) α-GTase from Thermotoga maritima overexpressed Escherichia coli using overexpression vectors. An IMO mixture containing 58% various IMOs was produced liquefied corn syrup by hydrolyzing transglycosylation activities BSMA alone. When reacted simultaneously, content increased 68%...

The samples were collected from 82 sites nationwide year 2012. mean range values As, Cd, Cu, Hg, Ni, Pb, Zn 4.41 (0.16-18.9), 0.25 (0.04-0.82), 13.24...

Over time, children's outdoor activities and opportunities for children to play, have continually declined. Such problems led increased interest in providing better physical environments active free play residential neighborhoods. Previous research studies generally focused on specific places (i.e. playgrounds schoolyards) or types of buildings apartment complexes). The primary goal this paper is identify the characteristics neighborhood that are associated with behavior by analyzing spaces...

For this, a questionnaire survey was performed from December 28, 2020, January 17, 2021. A total of 295 copies were used for final analysis, results found following: As perception others, impulsive buying, value orientation properties higher, problem awareness increased....

This study aims to draw the factors of support and restriction as children play in outdoor space through their participation. The 135 students (fifth- sixth- graders) participated research using mapping method included daily diagram open-ended questionnaire. As results, park, school yard, playground rest were emerged spaces with high utilization rate. Through analysis based on children's perception, physical social-psychological are drawn restriction. Some such location relevant friend...

The primary goal of this study is to derive implications for planning child-friendly apartment complexes through the analysis GPS data children's outdoor activities within an car-free complex. was conducted by following process: First, first-through-third grade elementary school students who reside in complex Jamsil area Seoul. Second, collected processed illustrate activity-density open spaces. Third, spatial characteristics and use-behavior high medium-density areas were analyzed. Fourth,...

Infants with developmental risk factors are more likely to have feeding problems and develop chronic disorders. Early detection understanding of the progression problematic its relationship a child's biological functioning family environment will enhance effective symptom management development interventions prevent pediatric

고유가와 자연환경에 대한 관심증대에 따른 선박의 환경규제로 많은 해운회사들이 어려움을 겪고 있으며 그에 따라 에너지 이용 효율성에 관심이 증대하고 있다. 또한 향후 시간이 흐를수록 이러한 문제들의 중요성과 관심은 점점 증대될 것으로 보인다. 이에 한 방안으로 독일의 Skyssails사가 4년간의 개발로 완성한 스카이세일즈 시스템은 새로운 관심을 가지게 한다. 이는 선박에 대형 연을 달아 연비를 낮추는 시스템으로 현재 유럽의 일부 실용화되고 있는 기술이다. 연의 활용과 관련이 깊은 국내연안의 날씨 등을 고려하여 동북아 피더네트워크가 발달되어 국내연안에서 Strysail 활용에 검토와 효용을 분석하고, 유류절감비용, 환경비용을 추정하였다. 그 결과 시스템이 보조추진기구로써 연비절감과 환경비용절감에 도움이 될 수 있음을 알 있었다. Many shipping companies have suffered about high oil cost and environment regulation...

풍력에너지는 20여년 전부터 새로운 대체 연료로서 주목받기 시작하여 현재는 글로벌 비즈니스 모델로 성장하고 있다. 전 세계적으로 풍력발전이 차지하는 비율은 전체 발전량의 30%를 차지하며, 이 지난 10여 년 간 꾸준히 증가해 왔다. 근래에 들어 일반 발전방식들의 탄소 배출량 증가 및 온실효과로 인한 환경문제 등으로 인해 풍력발전에 대한 국제적 수요는 점차 커져가고 본 연구에서는 이러한 풍력 발전용 부품에 효율적인 운송경로를 제안하기 위해 부품의 운송 특성에 따라 그 경로를 접근성 우선 경로, 경제성 편의성 경로 분류하였다. 연구를 통해 풍력발전부품 제조업체들은 제품의 운송기간의 문제 뿐 아니라 운송경로의 효율성과 경제성까지 판단할 수 있게 되었다. 즉 지금까지 선박회사나 포워더를 이루어지던 결정을 제조업체도 해당 경제성을 분석하고 비교할 Wind energy began to receive attention as a new alternative fuel since 20...

연구의 목적은 중학교 과학영재학생들의 R & E 프로그램으로, Cu (II) -M (M=Zn, Al, Fe)의 산화-환원반응에서 생성물의 형상과 반응속도에 미치는 구리(II) 이온의 농도, 활성 금속 (M) 및 음이온(spectator ion)의 영향에 대한 연구를 수행하는데 있다. 본 수행한 결과, 다음과 같은 결론을 얻었다. 첫째, CuSO4-Zn 0.5 M 황산구리 수용액 보다 진한 농도와 표면적이 큰 아연 분말을 사용하였을 때, 환원 생성물은 빠르게 붉은색 구리로 환원됨을 확인 하였다. 불균일 반응계인 Cu(II)-M의 산화-환원반응은 반응물의 농도가 증가하면 구리의 핵형성 속도가 증가하므로 초기 형성된 검은색 구리가 붉은색으로 변화되는 것을 알 수 있었다. 산화-환원반응의 진행에 따른 형상 변화는 0.2 CuSO4 수용액에서 가장 쉽게 확인할 둘째, 생성물인 형상은 사용하는 금속의 종류에 따라 다른 확인하였다. 반응성이 아연(Zn)과 알루미늄(Al)은 반응초기에...

The purpose of this study is to analyse the conditions neighborhoods in Seoul and propose improvements by residential neighborhood types activating children's outdoor play. Based on analysis 4 sites Southwest district, suggests following improvements. First, 'low-rise dense area', it use parks schools actively order solve problem lack play space neighborhood. Especially, school that hub connection point social networks should de considered actively. Second, 'residential mixed spaces...

Due to the recently changed environment, demand for logistics is increasing, and in particular, proportion of life services increasing. Logistics facilities with various functions are needed support these demands services. However, since there a limit expansion facilities, it necessary change thinking diversify use existing or new by breaking away from rigid supply mind. Based on this necessity, researcher presented ideas industrial complex.
 For purpose, I estimated collection-delivery...
