If we consider the cubism, which newly attempted the avant-garde movement in the mid-19th century, was an experimental movement to feel the space through the human action and observation from various viewpoints at the fixed three-dimensional world, then the futurism was an innovative movement that obtained an ion from continual motions. However, the study about meaning and emotion that correspond with the dis-structuralization era could not have been continuing. Therefore, the goal of this study is to construct an emotional theory and grope a possibility of the way to do through some theoretical investigations and experimental analysis about body movement and emotional expression. For the study method, experiment and analysis have been proceeded based on Miyauji study(1992) which was based on P. Thiel theory that is about direct recognition and empirical study for identical existence or experimentation. As a result of the study, it reached several conclusions. The first, body movement as an emotion that makes meaning is related to the space. The second is that the space is related to the background as an object of body. The last is that body as a creature which becomes the one with spirit in the space makes meaning. We look forward to a possibility of emotional study through the body movement.

An innovative interpretation of the per-unit interior permanent magnet (IPM) machine model known as Design Space is presented in this paper. Based on the proposed Design Space formulation, an effective computation method to predict IPM machine performance factors, such as the current and power factor in a full range of speeds, is proposed. A systematic methodology is summarized, which translates the full speed range machine design procedure into the region determination on the so-called Design Space. The effect of dc-link voltage is also analyzed in a similar manner with the current and power factor. A series of IPM motors have been designed, and a preferred motor is selected with the help of the proposed Design Space Methodology (DSM), which has the best tradeoff between the nominal voltage and the dropped voltage condition. Experiment results show that the selected motor satisfies the machine requirements and all the design constrains, such as the current and back-EMF limitations.

The purpose of this study was to know the differences in perceptual judgement for speech intelligibility in monosyllables by inexperienced listeners and vowel space area according to different dysarthric severity. Three dysarthric speakers with different severity(mild, moderate and severe) screened by 3 clinicians' screening tests before the experiment were conducted. Corner vowels (i, u, ae, a) in monosyllable level (CVC, 'p_p') and carrier phrases ('종이에_써') were chosen and analyzed for vowel space. Inexperience listeners (n=20) performed the intelligibility test for spoken syllables and carrier phrases by dysarthric speakers. The results show that there is a significant differences in both F1 and F2 values among 4 corner vowels. Vowel space area in the data of mildly impaired speakers was significantly higher than two others. In the scores of speech intelligibility judged by inexperienced listeners, the scores by a moderately impaired speaker were more higher than two other speakers. The discrepancy between perceptual judgement by inexperienced listeners and vowel space area will be discussed in this area.

Scientists at the International Space Station have been studying space life sciences to prepare for future manned space explorations, and require experimental specimen such as rodents for mass measurement. However, it is challenging to use mass measurement systems in space owing to the errors caused by factors such as mechanical-electronic noise. Therefore, to minimize the measurement errors, we propose a new algorithm called multiple calibration, which divides the mass range and calculates the sample weight by using the correction equation of each interval. We performed tests to evaluate and compare the performance of the proposed method to that of normal methods. As a result, the measurement accuracy improved by over two times using the multiple calibration method. Furthermore, we conducted mass measurements on various samples and confirmed that our method is valid for mass measurements.

This study analyzed the observation characteristics on space by analyzing through the visual perception experiment to the image dates from the original space and the rotated space of it. The results of this study are as fellow as: First, most frequently observed points were, lower end mainly from the center was more observed in the original space while upper end mainly from the center was more observed in the rotated space. Therefore, it is able for us to learn whether the space has the same design, the length of time focusing on one point differentiates as the image rotates. Second, differentiation in observation part, as shown in the case study, can be seen as a consequence of changes in perspective composition. The test indicates that when a design is presented to an observer, the observer's examining point would vary according to where the indoor perspective drawing places a vanishing point. Third, in zones I and II, observation was focused on lower end in the original picture while on the rotated picture there were more focus on the upper end and perpendicularity view of the indoor. Fourth, this study analyzed the mean value of the observation part. As one method wants to see how to change the observation characteristics by rotating the original space, few deviation from the mean value will be interpret to have similar observation characteristics over all even if it has the differences of watching place by rotated space.

노구치가 생각한 공간은 19세기와는 달리 고대 의식의 환경과 관련된 개념을 조각하고 이 개념을 조각적 공간에 포함시켰으며 또한 기술과 새로운 재료를 일상생활의 조각적 미학에 도입했다. 미술계뿐만 아니라 정원 조각, 무대 디자인 등에서도 공간에 대한 인식을 깨우쳐 주었다. 정원과 놀이터는 공간, 그 독특함을 보여주며, 그의 예술적 특성과 작품에 대한 연구의 결과로써 다음과 같은 결론을 얻을 수 있었다. 노구치의 작업은 동양의 미학을 서양의 모더니즘 양식에 결합함으로써 동 서양 예술의 합류점을 이루었으며, 예술의 사회적인 기능과 실용적인 미학 그리고 기능이 통합된 합리적 형태를 조형적 특성으로 하고있으며, 조각에 대한 그의 접근법은 공간이 최고라는 이해에 기반을 두고 있다는 것이다. 위의 연구 결과를 통해 알 수 있듯이 노구치의 공간적 조각은 상징적 표현과 재료에 대한 민감함, 예술가의 끊임없는 공간의 창출에 대한 노력으로 탄생된 것이며, 노구치에 대한 연구는 공간개념의 발전에도 도움이 될 뿐만 아니라 조형예술가에게도 기여할 수 있으리라 기대한다.

Infrared optical systems are operated at low temperature and vacuum (LT-V) condition, whereas the assembly and alignment are performed at room temperature and non-vacuum (RT-NV) condition. The differences in temperature and pressure between assembly/alignment environments and operation environment change the physical characteristics of optical and opto-mechanical parts (e.g., thickness, height, length, curvature, and refractive index), and the resultant optical performance changes accordingly. In this study, using input relay optics (IO), among the components of the Immersion GRating INfrared Spectrograph (IGRINS) which is an infrared spectrograph, a simulation based on the physical information of this optical system and an actual experiment were performed; and optical performances in the RT-NV, RT-V, and LT-V environments were predicted with an accuracy of $0.014{\pm}0.007{\lambda}$ rms WFE, by developing an adaptive fitting line. The developed adaptive fitting line can quantitatively control assembly and alignment processes below ${\lambda}/70$ rms WFE. Therefore, it is expected that the subsequent processes of assembly, alignment, and performance analysis could not be repeated.

In this study, the failure mechanism of sandwich-to-laminate T-joints under pull-off loading was investigated by experiment and the finite element method. A total of 26 T-joint specimens were manufactured and tested in order to investigate the effects of both adhesive thickness (0.4, 2.0, and 4.0 mm) and environmental conditions on the failure of the joints. The results showed that failure occurred mainly as intralaminar failure in the first layer of the sandwich face, which was contacted to the paste adhesive. The failure load did not significantly change with increasing adhesive thickness in both RTD (Room Temperature and Dry) and ETW (Elevated Temperature and Wet) conditions. In the case of ETW conditions, however, the failure load increased slightly with an increase in adhesive thickness. The joints tested in ETW conditions had higher failure loads than those tested in RTD conditions. In addition to the experiment, a finite element analysis was also conducted to investigate the failure of the joint. The stress inside the first ply of the sandwich face was of interest because during the experiment, failure always occurred there. The analysis results showed good agreement with the trend of experimental results, except for the case of the smallest adhesive thickness. The highest stress was predicted in the regions where initial failure was observed in the experiment. The maximum stress was almost constant when the adhesive thickness was beyond 2 mm.

The NASA Antarctica balloon experiment CREAM has successfully collected the data of energetic cosmic rays during flights in past years. We will present the recent analysis results of the CREAM experiment. We will also report on the launch and recovery process of the latest flight. The silicon charge detector of the CREAM has played the key role in the precision measurement of the charge constitution of energetic cosmic rays. We proposed the upgrade of the CREAM experiment with the installment of a new large silicon charge detector on top of the CREAM instrument. The charge measurement of the large silicon detector with no material in front is expected to improve the accuracy of the CREAM charge measurement drastically when combined with the measurement of the existing double layer silicon detector. We will present the fabrication of the large silicon detector and its performance in the radiation source test as well as in the beam test.
