The objective of this study was to investigate differences in clothing behavior and individual characteristics of female college students by their body cathexis and clothing attitude. The college students selected by random sampling were classified into four groups by their body cathexis and clothing attitude: positive congruity(positive body cathexis and clothing attitude, G1), positive incongruity(negative body cathexis and positive clothing attitude, G2), negative congruity(negative body cathexis and clothing attitude, G3), negative incongruity(positive body cathexis and negative clothing attitude, G4). The results were as follows: G1 was high in both public and personal self-esteem and self-image, extroverted, refined and impulsive. G2 were fashion opinion leaders, highly uneasy about society, highly impulsive, modem, peculiar, creative and introspective. G3 was highly uneasy about society, low in self-esteem, and less impulsive. G4 was low in both public self-esteem and fashion innovation, and avoided impulsive buying.

The proper design of man-machine systems requires as much understanding of the human element as of the machine. Although the modern systems engineer can obtain a very high degree of repeatability and accuracy for the characteristics of a machine, these of the human elements are much less well known. Due to the complexity and importance of modern man-machine systems, this difficult problem has recently received increasing attention. In this paper, the dynamic characteristics of the human operator have been newly determined by impulse estimation using Pseuo-random binnary signals as a test signal and the quasi-linear human operator models used as an element of a closed-loop control system adopted from McRuer & Krendel and Bekey. Also the techniques and instruments are presented for correlating the actual characteristics of the constructed system with anticipated theoretical values. Consequently, in spite of many problems remain yet, experimental results were very satisfactory.

The purpose of this study was to develop a standardized scale to measure consumption self-regulation. A preliminary 38-item scale was developed through a literature review. One thousand-twelve consumers responded to an online survey using the preliminary scale. A series of tests, such as test-retest, item-to-total correlation, Cronbach's reliability coefficient and factor analysis, were conducted using the survey data and a final scale comprising 30 items was then constructed. The consumption self-regulation scale consisted of four factors: (1) impulse control, (2) gratification delay, (3)self-reliance, and (4) self-management.

We developed a novel frame interpolation method to interpolate a frame between two successive original frames. Using this method, we are able to apply a double-rate driving method instead of an impulse driving method where a black frame is inserted between two successive original frames. The double-rate driving method enables amelioration of the motion blur of LCDs caused by the characteristics of human vision without reducing the luminosity of the whole screen. The image quality of the double-rate driving method was also found to be better than that of an impulse driving method using our motion picture simulator and an actual panel. Our initial model of our frame interpolation method consists of motion estimation with a maximum matching pixel count estimation function, an area segmentation technique, and motion compensation with variable segmentation threshold. Although salt and pepper noise remained in a portion of an object mainly due to inaccuracy of motion estimation, we verified the validity of our method and the possibility of improvement in hold-type motion blurring.

In this study, the dynamic analysis is performed fur predicting the transmitted force to flexible human body induced by prototype HIF(High Impulsive force) device operation, which is partially assembled by major parts. A beam-mass model and a shear-structure model are used for the flexible mount structure and their dynamic behavior are investigated by experimental results under rigid/flexible mount conditions using a general purpose device. From the test result of prototype device in rigid mount condition, the transmitted force to human body which can not be measured directly, is estimated based on the proved mount structure model.

We developed a novel Fame interpolation method to interpolate a frame between two successive original frames. Using this method, we are able to apply a double-rate driving method instead of an impulse driving method where a black Fame is inserted between two successive original Fames. The double-rate driving method enables improvement to the motion blur of LCDs caused by the characteristics of human vision without reducing the luminosity of the whole screen. Here, we report on the initial model of our frame interpolation method.

Channel-based radio-frequency fingerprinting such as a channel impulse response (CIR), channel transfer function (CTF), and frequency coherence function (FCF) have been recently proposed to improve the accuracy at the physical layer; however, their empirical performance, advantages, and limitations have not been well reported. This paper provides a comprehensive empirical performance evaluation of RF location fingerprinting, focusing on a comparison of received-signal strength, CIR-, CTF-, and FCF-based fingerprinting using the weighted k-nearest neighbor pattern recognition technique. Frequency domain channel measurements in the IEEE 802.11 band taken on a university campus were used to evaluate the accuracy of the fingerprinting types and their robustness to human-induced motion perturbations of the channel. The localization performance was analyzed, and the results are described using the spatial and temporal radio propagation characteristics. In particular, we introduce the coherence region to explain the spatial properties and investigate the impact of the Doppler spread in time-varying channels on the time coherence of RF fingerprint structures.

The purposes of this study were to identify clothing attitudes and purchasing motives according to consumption orientation of Chinese middle aged women. The results of this study were as follows: 1. Factors of shopping orientation were rich & fashion, economy & profit, traditional virtue & leisure utilizing, and frugality & pragmatism. Chinese middle aged women were classified into practicality pursuit group, material & fashion pursuit group, conservative leisure utilizing group, and negative stagnating group. 2. Factors of clothing attitudes were fashion, self-confidence & symbol, politeness, comfort, and luxury. Practicality pursuit group considered politeness of clothing more and did not purchase impulsively, but material & fashion pursuit considered many factors of clothing attitudes most. Conservative leisure utilizing group considered economy most, but negative stagnate group considered less. 3. Factors of clothing purchasing motives were fashion & conformity, fitness, impulse, and practical needs. Practicality pursuit group purchased clothing because of practical needs, but material & fashion pursuit group purchased of fashion & conformity, fitness, impulse, and practical needs.
