In this paper, the proprioceptive sensitivity was compared by Foot-Hand task method and the effect of the proprioceptive sensitivity and auditory to the standing position between blind and normal children was measured using BPM for 56 children in 7, 8, 9 and 10 years old. There are three measurement methods are used for BPM : Rest, Forward Looking, 'Sound' position. The following conclusions were obtained from the above measurements. 1. In comparison of proprioceptive sensitivity between blind and normal children, there is no significant difference(p > .05). There is no significant difference in comparison of each age group and also there is no difference in each gender group(p > .05). 2. In comparison of standing position measurement between blind and normal children, there is any difference (p > .05) in three measurement(Rest, Forward Looking, 'Sound' position) but there is no significant difference in each gender difference(p > .05). There is any difference between Rest and 'Sound' position of blind children, also there is any difference between Forward Looking and ' Sound ' position, rest and 'Sound' position of normal children(p > .05). 3. There is no significant difference of correlation between proprioceptive sensitivity test and standing position measurement in Pearson correlation coefficient(p > .05).

In tactical theater, it is crucial to detect ground moving targets and to locate them precisely. This problem can be resolved by using SAR (Synthetic Aperture Radar) sensors providing GMTI (Ground Moving Target Indication) capability. In general, to implement a robust GMTI sensor is not simple because of the strong competitions between target signals and clutter signals on the ground, and low speed of moving targets. Contrary to the case that a delay canceller is mostly suitable for ground surveillance radars, DPCA (Displaced Phase Centered Antenna) or STAP (Space Time Adaptive Processing) techniques have been adapted for GMT! function of modem airborne radars. In this paper, anew scheme of DPCA using two passive antennas with vertical separation is proposed, which also provides good clutter cancellation performance. The proposed scheme enables us to scan straight ahead of the carrying platform that is impossible with typical DPCA configuration. Simulations using various conditions have been performed to validate the proposed scheme, and the results are acceptable.

This article aims to review the monetary policy rule under inflation targeting framework focusing on Mongolia. The empirical analysis estimates the policy reaction function to see if the inflation targeting has been linked with a monetary policy rule emphasizing on inflation stabilization since its adoption in 2007. The study contributes to the literature by examining the linkage between Mongolian monetary policy rule and inflation targeting directly and thoroughly for the first time and also by taking into account a recent progress in the inflation targeting framework toward forward-looking mode. The main findings were: the Mongolian current monetary policy rule under inflation targeting is characterized as inflation-responsive rule with forward-looking manner (one quarter ahead); the inflation responsiveness is, however, weak enough to be pro-cyclical to inflation pressure; and the rule is also responsive to exchange rate due to the "fear of floating", which weakens the policy reaction to inflation and output gap.

In this study, we propose a method to improve the accuracy of acoustic odometry using optimal frame interval selection for Fourier-based image registration. The accuracy of acoustic odometry is related to the phase correlation result of image pairs obtained from the forward-looking sonar (FLS). Phase correlation failure is caused by spurious peaks and high-similarity image pairs that can be prevented by optimal frame interval selection. We proposed a method of selecting the optimal frame interval by analyzing the factors affecting phase correlation. Acoustic odometry error was reduced by selecting the optimal frame interval. The proposed method was verified using field data.

This paper addresses the effective and quantitative image DB construction for the development of front looking camera systems. The automotive industry has expanded the capability of front camera solutions that will help ADAS(Advanced Driver Assistance System) applications targeting Euro NCAP function requirements. These safety functions include AEB(Autonomous Emergency Braking), TSR(Traffic Signal Recognition), LDW(Lane Departure Warning) and FCW(Forward Collision Warning). In order to guarantee real road safety performance, the driving image DB logged under various real road conditions should be used to train core object classifiers and verify the function performance of the camera system. However, the driving image DB would entail an invalid and time consuming task without proper guidelines. The standard working procedures and design factors required for each step to build an effective image DB for reliable automotive front looking camera systems are proposed.

항공용 Multi-looking 카메라는 1대의 사진기 몸체에 5대의 카메라를 설치하여 동시에 1장의 연직사진과 4개의 경사사진을 획득하므로, 연직방향으로 촬영된 일반 항공사진에 비해 현장에 대한 다양한 정보를 제공한다. 그러나 3차원 공간정보 구축시 다각사진촬영시스템은 대형CCD를 사용하는것이 아니라 중형CCD를 사용하므로, 주요대상물의 전후좌우 영상을 취득하려면, 촬영시 중복도 설정을 고려하여야 하며, 특히 Sideward-looking 카메라의 경우 횡중복도 설정에 의해 특정대상물 촬영 여부를 확인할 수 있다. 이에 본 연구에서는 촬영시 횡중복도 변화에 의한 다각사진의 Sideward Footprint 및 촬영의 효율성에 대하여 분석하였다.

전방 감시 차량용 레이다에서 표적 거리와 속도 정보를 얻기 위해서는 일반적으로 주파수 변조된 연속파형(FMCW)이나 펄스 도플러(PD) 파형을 사용하고 있다. 그러나 고해상도의 표적 정보를 얻기 위해서는 펄스 폭이 매우 좁고 넓은 대역폭을 사용하여야 하므로 상대적으로 높은 첨두 전력이 필요하고 고속의 디지털 변환 처리속도가 요구된다. 본 논문에서는 계단 주파수 변조된 펄스 도들러 파형을 이용하여 고해상도의 표적 정보를 획득할 수 있는 SFPD(Stepped-frequency Pulsed-Doppler) 처리 기법을 제시한다. 제안된 SFPD 기법은 시뮬레이션을 통하여 기존의 FMCW 및 펄스 도플러 파형 방식과 비교 분석하였다. 본 기법은 필요에 따라서 거리 및 도플러 해상도를 가변할 수 있는 장점이 있기 때문에 이론적으로 고해상도의 표적 영상 형성이 가능하여 향후 정밀한 차량 충돌 방지를 위한 표적 식별에 활용할 수 있을 것으로 기대한다.

The purpose of this study is to verify the mediating effect of store benevolence for impact on store loyalty of store environment and store personality. For this study, data were collected through questionnaires. The survey ran from March to May, 2011, the total of 330 respondents was used in analysis. The subjects consisted of adults living in the Daegu and Gyeongsangbuk-do region, and convenience sampling. For statistical analysis, SPSS 19.0 were used to verify the study model. The major results of the study show that store benevolence may play a linkage role of store environment, store personality on store loyalty. The store benevolence variable has the effect of partial mediation. The analysis of relationship between the variables of store environment (convenience, information service accessibility, accessibility, variation) and the store type show significant differences store environment (convenience, information service and the store type). The analysis of relationship between the variables of store personality(warm, fun, sophisticated, forward-looking) and the store type show significant differences store personality (warm, fun, sophisticated, forward-looking) and store type. The analysis of relationship between the variables of store environment(convenience, information service accessibility, accessibility, variation), and the demographic variables show significant differences in store environment (information service accessibility) regarding only age. The analysis of relationship between the variables of store personality(warm, fun, sophisticated, forward-looking) and the demographic variable show significant differences in store personality(warm) regarding only age (accessibility, accessibility, variation).
