As a point that should be improved further in present SART, the size, the number, and the economy were enumerated. Some SART developed to solve them in Japan were introduced in this paper. That is automatically operating SART, circular polarization SART and so on. In addition, One Mile SART was mentioned. It is SART miniaturized instead of limiting the function, because all crews and passengers can always carry the small and light SART. The parts were made for trial purposes and the performance was confirmed.

SART(Search and Rescue Radar Transponder) is a radar transponder capable of operating in the 9GHz band, which is one element of GMDSS. The fundamental function of the SART is to indicate its position. Thus, it is so much available to assist SAR operation when an emergency and casualty occur at any sea area. In the thesis, we designed, manufactured each part of circuit to develop the advanced SART and configured to test the characteristics in many ways. As the result of detailed things, we confirmed that the developed SART could be high possibility of production.

이 연구는 급성관상동맥증후군을 경험한 환자의 상황인식 수준 측정을 위한 SART 도구의 신뢰도와 타당도를 검증하기 위해 시도되었다. 입원한 급성관상동맥증후군 환자 118명에게 번역된 SART 도구를 적용하여 도구의 신뢰도와 타당도를 분석하였다. 도구의 신뢰도와 타당도는 Cronbach 알파, 탐색적, 확인적 요인분석을 통해 분석하였다. 연구 결과 상황 인식 1(Instability of Situation, 상황의 불안정성)과 상황 인식 7(Spare Mental Capacity, 여분의 정신력)의 두 문항을 제거하였을 때 도구의 신뢰도와 모델 적합도 지수가 향상되는 것으로 나타났다. 수정된 국문판 SART는 급성관상동맥증후군 환자의 치료추구행동에 대한 의사결정 시 상황인식 정도를 측정하는 데 적절한 도구로 판단된다.

Inspection and shape measurement of three-dimensional objects are widely needed in industries for quality monitoring and control. A number of visual or optical technologies have been successfully applied to measure three-dimensional surfaces. However, those conventional visual or optical methods have inherent shortcomings such as occlusion and variant surface reflection. X-ray vision system can be a good solution to these conventional problems, since we can extract the volume information including both the surface geometry and the inner structure of any objects. In the x-ray system, the surface condition of an object, whether it is lambertian or specular, does not affect the inherent characteristics of its x-ray images. In this paper, we propose a three-dimensional x-ray imaging method to reconstruct a three dimensional structure of an object out of two dimensional x-ray image sets. To achieve this by the proposed method, two or more x-ray images projected from different views are needed. Once these images are acquired, the simultaneous algebraic reconstruction technique(SART) is usually utilized. Since the existing SART algorithms have several shortcomings such as low performance in convergence and different convergence within the reconstruction volume of interest, an advanced SART algorithm named as USART(uniform SART) is proposed to avoid such shortcomings and improve the reconstruction performance. Because, each voxel within the volume is equally weighted to update instantaneous value of its internal density, it can achieve uniform convergence property of the reconstructed volume. The algorithm is simulated on various shapes of objects such as a pyramid, a hemisphere and a BGA model. Based on simulation results the performance of the proposed method is compared with that of the conventional SART method.

In this paper, an X-band power amplifier using GaAs FET was designed and fabricated, which is to be used as SART transmitter sweeping at the frequency range of 9.2 GHz~9.5 GHz. The amplifier is consist of two stages using ATF-46101 FET of Hewllett-Packard. Finally, the amplifier using microstrip line matching solution shows that MAG is 23 dB at the center frequency of 9.35 GHz.

This paper is devoted to the examination of the identity of the Sogdian descendants and their historical role in the second millennium CE. More specifically, it discusses the Sogdian connection to the later Iranic-speaking peoples of Central Asia, namely, the Sarts and the Tajiks. It then discusses the symbiotic relationship between the Sogdian descendants and the Mongols and the Mongol descendants (Chaghatays and Uzbeks) in Central Asia. In sum, this paper argues that the Sogdians did not perish after the Arab conquest of Central Asia in the eighth century CE. They survived under new exonyms Sart and Tajik. Like the Sogdians in pre-Islamic Central Asia, the Tajiks or Sarts played important historical roles in the Mongol and post-Mongol states of Central Asia, maintaining a symbiotic relationship with the nomad elites.

본 연구는 창업교육이 대학생들의 창업에 대한 인식을 높이고 상황에 맞는 역할을 할 줄 아는 유연하고 창의적인 인재를 양성하기 위하여, 본 연구에서는 SCH대학교에서 신입생 대상으로 실시한 기업가정신 교육을 받은 학생들을 대상으로 설문조사를 실시하였으며, 회수된 설문지는 SPSS와 SmartPls 2를 이용하여 분석되었다. 분석 결과, 첫째, 성취욕구와 학업적 자기효능감은 학습몰입과 기업가정신이 학생들이 창업교육을 받음으로써 미래의 삶과 자신의 목표를 위하여 달성 가능한 목표를 세우고, 예측가능 하지 않은 문제들을 해결하는데 도움이 될 수 있다는 관점에서 이루어져야 한다는 것을 제시해주고 있다. 둘째, 창의성은 학습몰입에 유의한 영향을 미치지 않으나, 기업가정신은 창업교육에 참여하는 학생들의 창의성이 높을수록, 학습몰입보다는 기업가정신이 더 높아진다는 것을 의미한다. 셋째, 학습몰입은 기업가정신에 유의한 영향을 미치나, 창업의도에는 직접적으로 유의하지 않으나, 기업가정신은 창업의도는 창업교육으로 인하여 학습몰입이 높은 대학생일수록, 기업가정신이 높아지고, 그 결과 창업의도가 높다는 것을 의미한다. 마지막으로, 본 연구의 한계점 및 향후 연구방향은 표본이 SCH대학교의 1학년 학생들만을 대상으로 연구되었다. 향후 창업교육을 시행하고 있는 모든 대학교의 참여 대학생들을 대상으로 연구하여 비교분석할 필요가 있다.
