It has been reported that a rapid elevation in the intracranial pressure is associated with increased arterial pressure, reduced heart rate and irregular respiration. In the present study an effort was directed to observe the possible blocking effect of dibenzyline, an alpha-sympathetic blocking agent, administered prior to the intracranial pressure elevation. Alhino rabbits were divided into two experimental groups: in one group, the intracranial pressure was raised by infusing normal saline into the extradural space and was sustained for 30 minutes, while in the other group, dibenzyline(12mg/kg B.W.) was administered 16 hours prior to the intracanial pressure elevation. In both groups, the arterial pressure, heart rate and respiratory rate were measured for 30 minutes at 5 minuteintervals. In the intracranial pressure elevated group, the arterial pressure increased to 99 mmHg at 10 minutes in comparison with 88mmHg in the beginning. At 25 minutes, it returned to or near its initial level. The slowing of the heart rate was seen toward the end of the response, i.e. in the beginning, 269 rate/min, at the end, 214 rate/min. The respiratory rate did not show any significant change. In the dibenzyline pretreated group, the arterial pressure and heart rate did not change markedly from the initial levels. From the above result, it can be stated that dibenzyline has blocking effects on the increased arterial pressure and reduced heart rate in rabbits during increased intracranial pressure.

In this paper, a trajectory tracking problems using SMC(sliding mode control) is presented. In the conventional method. SMC has been applied to linear systems and the output matrix C has to satisfy a restrictive condition that CB is nonsingular. Under suitable assumptions, decoupling SMC can be adapted to remove the restriction mentioned above. The Proposed control strategy is applied to trajectory tracking control and simulations results are given to demonstrate the effectiveness of the proposed control scheme.
지역통상정보 : 부가가치지적계수(VAIC) 모형을 이용한 한국 금융서비스 분야의 국제경쟁력 비교 분석

이 연구에서는 Pulic 등의 부가가치 지적계수(Value Added Intellectual Coefficient, VAIC) 모형을 이용하여 한국의 은행, 증권사, 보험사 등의 지적자본 효율성을 측정하고, 지적자본을 구성하는 인적, 구조적, 물적 자본과 금융기관의 경영성과 간의 상관관계 및 유의성을 분석하였다. 분석 결과 국내 금융회사중 부가가치 지적계수(VAIC) 및 인적자본 효율성 계수(HCE)는 은행, 보험, 증권 순으로 높았다. 한편, 아시아 주요국 및 세계 10대 은행들과 비교해 볼 때 한국을 포함한 선진국 은행들이 개도국 은행보다 VAIC와 HCE가 높은 것으로 나타났다. 다만, 한국은 호주 등에 비하여 VAIC 및 HCE가 낮은 수준인 것으로 나타났으며 최근 들어 그 수치가 하락세에 있는 것으로 나타났다. 한국 금융서비스 분야의 국제경쟁력 제고와 더불어 한국 금융산업이 해외시장 진출을 추진하는데 있어 시사점을 제시하고 있다. This study measures the efficiency of intellectual capital of Korea``s banks, financial investment companies, and insurance companies using the Value Added Intellectual Coefficient (VAIC) model, which was developed by A. Pulic and investigates into the relationship of each of VAIC’s elements - efficiency of human, structural, and material capital - with business performance of the institution. We found, first, average VAIC and human capital efficiency(HCE) of Korean financial institutions during 2001 - 2012 were highest among banks, followed by insurance companies and securities firm. Secondly, in general, banks in advanced countries tend to have higher HCE and VAIC compared with the banks of developing countries. Thirdly, Korean financial institutions`` HCE and VAIC are lower than those of Australia and even Taiwan and Thailand and have been on the decrease in recent years. This suggests that Korean financial institutions should enhance VAIC and HCE to enhance their international competitiveness.
Manipulation of a Micro Droplet in a Capillary Tube by Using a Flexural Acoustic Wave
박재식,김성현,이민환,김은선,황인각 한국물리학회 2019 새물리 Vol.69 No.7
We demonstrated the precise motion of a nanoliter-volume oil droplet in a capillary tube by using a flexural acoustic wave. An acoustic standing wave was excited between a compact co-axial acoustic transducer and the free end of the capillary tube. The liquid droplet was trapped at an antinode of the standing wave thus, the position of the droplet could be controlled by tuning the positions of the acoustic antinodes or the acoustic frequency. The position control was achieved over the entire length (15 cm) of the acoustic interaction region of the capillary tube to a precision of a few tens of m.

Noise maps are produced according to ‘The Method of making a Noise Map’ in order to noise control efficiently, and prediction model to predict road traffic noise which may apply to Korean situation, include CRTN, RLS 90, NMPB, Nord 2000 and ASJ 2003. Of them, ASJ 2003, Japans prediction model has not been verified for the application to Korean situation according to the classification of vehicle. In addition, ASJ 2003 was revised to ASJ 2008 recently, a classification for motorcycle was added. This study attempts to check the classification of vehicle in ASJ 2008 and ‘The Method of making a Noise Map’ to confirm the suitability of the application of them to Korean situation.
