This study deals with the distribution and morphological study of the neurons with the neuropeptide Y (NPY) in developing chick brain. The developing brains of Korean native chicks at embryonic days 8 (E8), E10, E12, E14, E16, E18, and E20 were used. The chicks were perfused with 4% paraformaldehyde through the left ventricle and aorta. The brains were removed and transferred into 30% sucrose, and then cut in a cryostat into $60{\mu}m$ in thickness. The sections were immunostained with free-floating and avidin-biotin complex (ABC) methods. The numerous neurons with NPY were first observed in nucleus rotundus of diencephalon at E8. In particular, neurons in nucleus rotundus had the well-developed processes. At E12, the neurons with NPY were distributed widely in diencephalon; nucleus septalis lateralis, medialis, nucleus magnocelluaris preopticus dorsalis, medialis, ventralis, nucleus preopticus medialis, nucleus dorsolateralis anterior thalami pars magnocellularis, and nucleus paraventricularis magnocellularis (paraventricular nucleus) except nucleus rotundus. From E12 to E20, positive neurons were oval-shaped, changed gradually into the spherical- and multipolar-shaped. The shapes of processes were also omnidirectional and the number of those were less than in telencephalon. As the chicks developed, the morphology of neurons with NPY showed the tendency to increase in their sizes and numbers.

이미영,김승수 ( Mi Young Lee,Soung Soo Kim ) 생화학분자생물학회 1990 BMB Reports Vol.23 No.4

A far migrating anionic isoperoxidase, named A₃, was isolated from Korean radish (Raphanus sativas L.) root. Purification of the enzyme was accomplished by CM-cellulose chromatography, DEAF-Sephacel chromatography and Sephadex G-75 gel filtration. The enzyme was a glycoprotein having molecular weight of approximately 50,000 as determined by SDS-PAGE and Sephadex G-150 gel filtration and the pI value was 3.0. The optimum pH of the enzyme was 6.0 for guaiacol and H₂O₂and the Km values for guaiacol and H₂O₂ were 8 mM and 1 mM, respectively. Substrate studies with natural phenolic compounds were performed and their Km values were determined. In comparison with other Korean radish isoperoxidases, A₃ had higher affinity for esculetin. A particular interest is that the enzyme showed as sigmoidal substrate saturation curve against scopoletin despite of its single Subunit structure.

건설업 산업재해발생율 평가지표 개선방안

이미영,오세욱,임세종,Lee, Miyoung,Oh, Sewook,Lim, Sejong 한국건설관리학회 2016 건설관리 : 한국건설관리학회 학회지 Vol.17 No.5

국내 건설재해율은 1992년 도입된 이후 현재까지 PQ에 '환산재해율' 반영 등을 통하여 건설재해 감소 및 건설업 안전관리 체제 구축에 기여하고 있다. 또한, 최근 정부가 도입 추진 중인 종합심사낙찰제에도 '재해율' 및 '사망만인율'이 평가항목으로 구성되어 입 낙찰제도의 그 영향력이 확대되고 있다. 그러나 현행 건설재해율은 입 낙찰제도에 따라 이원화된 기준으로 산정 및 운영되고 있는 실정이므로 현 시점에서 건설재해율 평가지표에 대한 현황 검토와 효율적 운영을 위한 방안이 모색될 필요성이 대두되고 있다. 이에 본 연구에서는 건설업체의 재해관리 실무자를 대상으로 설문조사를 실시하여, 현행 건설재해율의 평가 운영에 대한 현황 검토를 통하여 문제점을 분석하고 그에 따른 개선방안을 제시하였다. 연구 결과, 건설재해율 평가지표의 일원화를 위한 산정기준, 평가대상업체 범위 설정, 건설업 공상처리 개선 측면에서의 개선방안을 제시하였다. 제시된 개선방안을 통해서 보다 효율적이고 합리적인 건설재해율 평가지표의 산정 및 운영이 가능할 것이며, 나아가 건설업체의 자율적인 안전보건 활성화 등을 통한 건설 재해 감소 효과를 기대할 수 있을 것이다. Since the introduction of the converted accident rate in Pre-Qualification(PQ) process in 1992, the safety evaluation system has contributed to a reduction of construction accidents and development of the safety management system in public construction projects. As the comprehensive evaluation method the government plans to introduce includes the indicators 'accident rate' and 'death rate per 10,000 workers', the influences on the safety evaluation in the bidding process would be broader in public sector construction projects. However, the current safety evaluation system is operated by different estimating standards in the bidding process. At this point, a study of improvement on the safety evaluation index is required to review its current conditions and to propose its efficient operating method. Therefore, the purpose of this study is to analyze problems of the current safety evaluation system through the questionnaire survey on the qualified workers in construction safety management and to propose an improvement plan for the problems noticed. Our results suggest the standards of the unified process for the safety evaluation index, the size of construction firms needed for accident rate estimation, and the improvement plan for unreported accidents. The proposed improvement plan enables the reasonable estimation and efficient operation of the safety evaluation index, and further, it would contribute to reducing construction accidents through the activation of voluntary safety management by construction firms.

한국산 무우 묘목의 성장에 따른 Peroxidase isozyme 들의 조직특이성 발현

이미영,김승수 ( Mi Young Lee,Soung Soo Kim ) 생화학분자생물학회 1990 BMB Reports Vol.23 No.4

Changes in the pattern of isoperoxidases and the specific activity of peroxidases were examined from cotyledone, hypocotyl and root portion of the Korean radish seedlings grown for 3, 5 and 7 days. The specific activity of peroxidases was very high in the root compared with that of hypocotyl and cotyledone portion of the seedlings and peroxidase isozyme patterns in these three organs were changed during entire growth periods. Total cellular RNA was isolated from hypocotyl and root portion of the seedlings with guanidium thiocyanate and guanidine HCl method. The total RNA was further fractionated by oligo (dT)-cellulose chromatography. For translation of peroxidase mRNAs in cell-free protein synthesizing system, rabbit reticulocyte lysate was tested and the optimum translational conditions of peroxidase mRANs were determined. The poly(A) +RNA and poly(A)-RNA isolated from hypocytyl and root portion of the seedlings grown for 5 and 7 days were translated in vitro and the correlation between the changes in the expression pattern of isoperoxidases and qualitative and quantitative changes in peroxidase mRNA populations was investigated. The peroxidase activity of poly(A)-RNAs was much higher than that of poly(A)+RNA in seedlings grown for 7 days when compared with that of poly(A)-RNAs from seedlings grown for 5 days.

Ag Pastes의 분산 특성 및 스크린 인쇄된 OTFTs용 전극 물성

이미영,남수용,Lee, Mi-Young,Nam, Su-Yong 한국전기전자재료학회 2008 전기전자재료학회논문지 Vol.21 No.9

We have fabricated the source-drain electrodes for OTFTs by screen printing method and manufactured Ag pastes as conductive paste. To obtain excellent conductivity and screen-printability of Ag pastes, the dispersion characteristics of Ag pastes prepared from two types of acryl resins with different molecular structures and Ag powder treated with caprylic acid, triethanol amine and dodecane thiol as surfactant respectively were investigated. The Ag pastes containing Ag powder treated with dodecane thiol having thiol as anchor group or AA4123 with carboxyl group(COOH) of hydrophilic group as binder resin exhibited excellent dispersity. But, Ag pastes(CA-41, TA-41, DT-41) prepared from AA4123 fabricated the insulating layer since the strong interaction between surface of Ag powder and carboxyl group(COOH) of AA4123 interfered with the formation of conduction path among Ag powders. The viscosity behavior of Ag pastes exhibited shear-thinning flow in the high shear rate range and the pastes with bad dispersion characteristic demonstrated higher shear-thinning index than those with good dispersity due to the weak flocculated network structure. The output curve of OTFT device with a channel length of 107 ${\mu}m$ using screen-printed S-D electrodes from DT-30 showed good saturation behavior and no significant contact resistance. And this device exhibited a saturation mobility of $4.0{\times}10^{-3}$ $cm^2/Vs$, on/off current ratio of about $10^5$ and a threshold voltage of about 0.7 V.

KSLA 연구논문 - 박물관내 도서관 운영 현황 및 전문도서관으로의 발전 전략

이미영,Lee, Mi-Yeong 한국전문도서관협의회 2010 KSLA bulletin Vol.2 No.-

박물관내 도서관은 인력, 예산, 조직내 인식 부족 등으로 본연의 기능을 전문적으로 수행하지 못하였다. 박물관내 도서관이 전문도서관으로서 보다 발전하기 위한 전략을 해외사례에서 찾고자 하였다. 그 결과, 관리자에서 수집가로서 사서의 역할 변화, 특성화된 컬렉션 확대, 기관 아카이브의 기능 수행, 도서관간 협력 네트워킹 구축 등을 발전전략으로 제시하였다. The lack of human resource, budget and understanding in organization didn't allow the library in museum to accomplish its function fully. I tried to find the development strategies toward special library in abroad cases. As a result, I suggested the librarian's role change from manager to collector, the expansion of the specialized collection, the function as institutional archives, the construction of networking between libraries.
