research is carried to schedule the nodes in ubiquitous sensor networks to reduce energy consumption, maximize the throughput, for effective prolonged network lifetime, scalability, and load balancing. Each ubiquitous node in USN should forward data to the base station. In Data Aggregation methods each node need not directly forward data to the base station instead it may forward data to a special node called head node which in turn forwards data to the base station. In this paper we proposed a... -

Attenuated functional exercise capacity in elderly and diseased populations is a common problem, and stems primarily from physical inactivity. Decreased function and exercise capacity can be restored by maintaining muscular strength and mass, which are key factors in an independent and healthy life. Resistance exercise has been used to prevent muscle loss and improve muscular strength and mass. However, the intensities necessary for traditional resistance training to increase muscular strength... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2011, Vol.15 No.4 5 217-239 (23 pages)
We carried out a series of experiment demonstrating the role of mitochondria in the cytosolic and mitochondrial Ca2＋ transients and compared the results with those from computer simulation. In rat ventricular myocytes, increasing the rate of stimulation (1∼3 Hz) made both the diastolic and systolic [Ca2＋] bigger in mitochondria as well as in cytosol. As L-type Ca2＋ channel has key influence on the amplitude of Ca2＋-induced Ca2＋ release, the relation between stimulus frequency and the... -
Ca2+-induced Ca2+ Release from Sarcoplasmic Reticulum Negatively Regulates Myocytic ANP Release in Beating Rabbit Atria

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2005, Vol.9 No.2 3 87-94 (8 pages)
It is not clear whether Ca2-induced Ca2 release from the sarcoplasmic reticulum (SR) is involved in the regulation of atrial natriuretic peptide (ANP) release. Previously, we have shown that nifedipine increased ANP release, indicating that Ca2 entry via voltage-gated L-type Ca2 channel activation decreases ANP release. The purpose of the present study was two-fold: to define the role of SR Ca2 release in the regulation of ANP release and whether Ca2... -

Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 1 67-77 (11 pages)
Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -

As a part of the electromagnetic spectrum, microwaves heat materials fast and efficiently via direct energy transfer, while conventional heating methods rely on conduction and convection. To date, the use of microwave heating in the research of carbon-based materials has been mainly limited to liquid solutions. However, more rapid and efficient heating is possible in electron-rich solid materials, because the target materials absorb the energy of microwaves effectively and exclusively.... -

In Mongolia, the regulation related to the private security industry, the Law on Contracted Private Security Services, was legislated relatively recently. The Law on Contracted Private Security Services was enacted into law in Mongolia 16 years ago, in 2000. This regulation has undergone two amendments since its inception. However, new revisions still need to be made to ensure that this regulation is in line with internationally accepted standards and practices. This paper compares the existing... -

최근 전력계통의 대형화와 중조류 설비의 증가 등으로 계통내부에서 소모되는 무효전력 급증에 따라 계통전압관리차원에서 부하역률 관리의 중요성이 새롭게 대두되고 있다. 따라서 본 논문에서는 최소자승법(Least Square Method)을 이용하여 변압기 무효전력 손실량을 산출하였으며, 유량평균법(Average Flow Method)을 사용하여 부하특성에 따른 지역별, 계절별, 시간대별 부하역률 대표모델을 수립하였다. -

화석연료의 고갈에 따른 연료유의 가격상승과 세계온난화에 따른 그린하우스가스(Green House Gas, GHG)등의 문제가 주목받고 있다. 이러한 이유로 해상운송사업은 연료의 소비를 줄이고 환경보호를 위해 온실가스를 줄이기 위한 친환경선박(Green ship) 기술에 대하여 관심을 보이고 있다. 선박의 전력시스템은 안전한 운항을 위한 가장 주요한 요소 중 하나이다. 이러한 이유로 선박 설계에 있어 대부분의 선박은 바우 스러스터(Bow thruster, B/T), 크레인 등의 장비사용에 따른 피크부하로 인하여 큰 용량의 발전기를 사용하고 있다.... -
