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.

The purpose of this study was to test the reliability and validity of the SART(Situation Awareness Rating Technique) tool to measure the situational awareness of patients with acute coronary syndrome. The translated SART was tested on 118 hospitalized patients with acute coronary syndrome to verify the reliability and validity of the tool. The analysis was conducted with Cronbach's alpha, exploratory & confirmatory factor analysis. Study findings found that the tool's reliability and model fit index improved when the two problematic items, namely, Situation Awareness 1 (Instability of Situation) and Situation Awareness 7 (Spare Mental Capacity) were removed. According to the results, the revised K-SART is deemed to be an appropriate method for assessing the degree of situational awareness of patients with acute coronary syndrome in decision making about treatment-seeking.

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.

The major results of the study are as follows: First, the accomplishement needs and academic self-efficacy enables students with start-up education through studying immersion and entrepreneurship to set up realistic objectives for personal life and resolving unpredictable problems. Second, creativity does not significantly affect studying immersion, but the higher the creativity of students participating in start-up education, the higher the entrepreneurship compare to studying immersion. Third, studying immersion has a significant impact on entrepreneurship, but has less impact on student's intention for start-up. Students with higher studying immersion through start-up education has higher entrepreneurship spirit and as a result, higher intention for start-up. Finally, the limitation of the study was that the sample was taken only from the freshman of Soonchunhyang University. Therefore, further study is needed for students from all university with start-up education.
