low-velocity impact load on carbon fiber reinforced polymer (CFRP) composite plates fabricated with various stacking sequences were studied experimentally. The impact responses of the CFRP composite plates were significantly affected by the laminate stacking sequences. Three types of specimens, specifically quasi-isotropic, unidirectional, and cross-ply, were tested by a constant impact carrying the same impact energy level. An impact load of 3.44 kg, corresponding to 23.62 J, was applied to the... -

and high rigidity [1]. In particular, the fuselage and wings of various aircraft, as well as the load bearing structures and components of mechanical and civil engineering systems are currently being manufactured with CFRP. However, even a low velocity impact on the carbon fiber reinforced composites can cause considerable damage, including matrix cracking, fiber failure and delamination [2-6]. These damages can result in the dramatic loss of strength and stiffness of the composites [7-9]. -

The quantitative sudomotor axon reflex testing (QSART) is a classic test of routine postganglionic sudomotor function. We investigated sudomotor function by QSART after summer (July 2012) and winter (January 2013) seasonal acclimation (SA) in the Republic of Korea. QSART with acetylcholine (ACh) iontophoresis were performed to determine directly activated (DIR) and axon reflex-mediated (AXR1, 2) sweating rate.

Tonic smooth muscle exhibit the latch phenomenon: high force at low myosin regulatory light chains (MRLC) phosphorylation, shortening velocity (Vo), and energy consumption. However, the kinetics of MRLC phosphorylation and cellular activation in phasic smooth muscle are unknown. The present study was to determine whether Ca2＋-stimulated MRLC phosphorylation could suffice to explain the agonist- or high K＋-induced contraction in a fast, phasic smooth muscle. We measured myoplasmic [Ca2＋], MRLC... -

Tropical natives (TROP) are capable of tolerating tropical heat because of their long-term adaptation to tropical environments. When exposed to heat stress, these natives tend to respond with lower sweat output, which is generally thought to be the result of heat acclimatization. The main objective of this study was to clarify central mechanisms inherent to suppressed thermal sweating in tropical natives (Malaysians) by comparing their sweating responses to those of temperate native (TEMP)... -
Economical Sweating Function in Africans: Quantitative Sudomotor Axon Reflex Test

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2004, Vol.8 No.1 4 21-25 (5 pages)
People in tropics have the ability to tolerate heat by residential permanence in the tropics. Previously, we have shown that African and Thai subjects who lived for whole their lives in only their respective countries sweat less under hot conditions than South Koreans who also lived whole their lives in Korea. The difference in sweating responses was attributed to the dissimilar central and peripheral sweating mechanisms operating in people from both groups. In the present study, acetylcholine... -

수축의 크기는 Ca2+없는 용액으로 처리시간이 증가함에 따라 감소하며 10분후 완전 소실되었다. 9) Ca2+없는 용액으로 처리시간이 길어질수록 0.5mM Ca2+에서 10-7M SP에 의한 수축은 감소하였다. 10) Ca2+없는 용액에서 10분간 처리한 후 10-7M SP에 의한 수축은 Ca loading time이 길수록 외부 Ca2+농도가 높을수록 증가하였다. 이상의 결과로 볼 때 저농도의 SP는 주로 외부 Ca2+의 유입에 의해 수축을 일으키는 것으로 생각되며 이 Ca2+의 유입에 관여하는 기전은 K+투과도의 감소에 의한 막전위의 탈분극만으로 완전히 설명할 수... -

완성도 높은 보철물을 위해서는 기능성과 생물학적 요건 그리고 심미성을 만족 시켜야 한다. 최근들어 심 미적인 면에 대한 관심이 증가하면 치과 치료 전반에 걸쳐 심미성을 강조하는 술식과 재료들이 많이 보급 되고 있다. 보철분야의 심미 수복재료는 도재와 복합 레진 수복물이 주로 사용되고 있는데 금속 도재는 장 기간의 안정된 예후를 보이나 하부의 금속 구조물로 인해 심미성에 한계가 있으며 복합레진의 경우 변색 이나 마모 등의 한계가 있다. -

Hearing impairment is one of the most common physical disabilities in the world. Conductive hearing loss results from dysfunction of the middle ear, and sensorineural hearing loss results from abnormalities within the cochlea or central nervous system. To improve the diagnosis of hearing loss and develop new technologies for restoration of hearing, changes of the middle ear and cochlear functions in relation to ear structural disorders in hearing impaired ears need to be characterized. This... -

Nitrogen (N)-doped ordered mesoporous carbons (OMCs) with a dual transition metal system were synthesized as non-Pt catalysts for the ORR. The highly nitrogen doped OMCs were prepared by the precursor of ionic liquid (3-methyl-1-butylpyridine dicyanamide) for N/C species and a mesoporous silica template for the physical structure. Mostly, N-doped carbons are promoted by a single transition metal to improve catalytic activity for ORR in PEMFCs. In this study, our N-doped mesoporous carbons were... -

It critically reviews measured mercury emissions progress in the development of promising control technologies. This review provides useful information to scientists and engineers... -
Superhydrophobic carbon-based materials: a review of synthesis, structure, and applications
Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 16 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 5 89-104 (16 pages)
Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

한국습지학회 한국습지학회지 2016, Vol.18 No.4 13 448-455 (8 pages)
the Ministry of Environment (MOE) resulted to the construction of pilot facilities termed Best Management Practices (BMPs). Twelve BMPs installed for the diffuse pollution management in the Kyung-An Stream were monitored since 2006. Data on the mass loading, removal efficiency, maintenance activities, etc. were gathered and utilized to conduct the evaluation of long-term performance of BMPs. The financial data such as actual construction, design and maintenance cost were also collected to evalua... -
고속도로 강우유출수 처리를 위한 우드칩 충진 침투도랑의 성능평가
