Purpose: Micro-computed tomography (micro-CT) has been widely used in the evaluation of regenerated bone tissue but reliability micro-CT not yet established.This study evaluated correlation between histomorphometric analysis and performing new formation measurement.Methods: Critical-size calvarial defects were created using a 8 mm trephine bur total 24 Sprague-Dawley rats, collagen gel mixed with autogenous rat marrow stromal cells (BMSCs) or BMSCs transduced by adenovirus containing...
Parnassius bremeri (P. bremeri), a member of the genus Snow Apollo in swallowtail family (Papilionidae), is high alpine butterfly that lives Russia, Korea, and China. It an endangered wildlife (Class I) South Korea globally species. The lack transcriptomic genomic resources P. significantly hinders study its population genetics conservation. detailed information developmental stage-specific gene expression patterns great demand for However, molecular mechanism underlying metamorphic...
Atopic dermatitis (AD) is a chronic inflammatory skin disease which requires continuous treatment due to its relapsing nature. The current includes steroids and nonsteroidal agents targeting inflammation but long-term administration causes various side effects such as atrophy, hirsutism, hypertension diarrhea. Thus, there an unmet need for safer effective therapeutic in the of AD. Peptides are small biomolecule drugs highly potent remarkably have less effects. Parnassin tetrapeptide with...
The retained charge (memory window) of a ferroelectric capacitor measured by the pulse method is smaller than that continuous wave method. This attributed to relaxation phenomenon which represents fast loss remanent polarization after removal applied voltage. induced depolarization field affected various parameters such as properties and thickness film, measurement temperature, electrode material formation an interfacial layer between film electrodes. In this study, effects each parameter...
Three species of Lepidoptera: Hendecaneura impar (Walsingham) Tortricidae, Deltoplastis apostatis (Meyrick) Lecithoceridae, and Doratoptera virescens Marumo Geometridae, are reported for the first time from Korea. Styrax obassia Siebold Zucc. is known larval host plant H. Impar: larvae were collected reared with leaves until emergence. Images adults their female genitalia provided, a photo larva given.
A method for the modeling of polarization-electric field (P-E) hysteresis curves ferroelectric thin film with asymmetric electrode configuration was developed. The curve capacitor materials is shifted due to work function difference between top and bottom electrodes apparent polarization values are reduced as screening length increases.
An embedded ferroelectric random access memory (eFRAM) with an electrical fuse (e-fuse) repair scheme, in which the information can be electrically programmed, was successfully developed for a high performance smart card. From viewpoints of security and cost-efficiency, e-fuse scheme cell is best way to improve yield We realized flexible efficient by controlling it signals addresses. The successful operation confirmed fixed attempt ratio over 95%. Additionally, one time programming cells...
Classical antibiotics are the foremost treatment strategy against microbial infections. Overuse of this has led to evolution antimicrobial resistance. Antimicrobial peptides (AMPs) natural defense elements present across many species including humans, insects, bacteria, and plants. Insect AMPs our area interest, because their stronger abilities in host defense. We have deciphered from an endangered Parnassius bremeri, commonly known as red spotted apollo butterfly. It belongs second largest...

디지털 앱북은 기존의 전자책에서 발전한 형태의 멀티미디어 콘텐츠로서 동영상, 소리뿐만 아니라 모바일 기기의 센서를 이용한 다양한 상호작용을 지원할 수 있는 장점이 있다. 발전으로 이러한 앱북의 수요는 폭발적으로 증가하고 있지만, 지원하기 위해서는 프로그래밍 제작 노력이 많이 필요하기 때문에 공급이 그 늘어난 수요를 따라가기 힘든 실정이다. 문제를 해결하고자, 본 논문은 자연과학 교육용 흥미를 느끼게 해주는 핵심 요소인 사용자-기기간 상호작용 기능들을 라이브러리로 구현하고 검증하였다. 제안 라이브러리는 사용자 동작 인식부, 기기 동작부, 콘텐츠 동작부로 구성되며, 각 부의 명령을 조합하여 함수를 제공한다. 설계는 코드의 재사용성, 개발자의 쉬운 이해와 활용성, 넓은 확장성을 구현된 상용화를 위한 앱북 제작에 직접 이용되었으며, 결과 코드 사용량을 크게 줄이고 개발 시간을 단축함으로써 효율을 높일 있었다. The digital app-book is an advanced form...
Purpose: The aim of this study was to investigate the effects EMD on demineralized root surface using human periodontal ligament cells and compare conditioning materials(tetracycline(TCN), EDTA).
