In this thesis, Improvisation of Jazz Vocal that can be characterized as Jazz music, namely practice of Scat suggest that way of applied approach that root position of chord and chord tones. Scat plays a solo using reproduced tunes of meaningless scat syllable that is not use the lyrics and melodies, which are written in a score. For this, Using the root position of chord is a reference point that Jazz vocal constructs a musical melody. Singing person can develop that reference point from simple scat to develop increasingly complex scat and can express that musical expression and communion. It analyzed the music functionally with a standard Jazz music 'All of me' as the center from composition of chord tone that improvise song to bass line, bass scat, analysis of chord tones arpeggio and expression. In this thesis, the improvisation of a Jazz vocal that may seem somewhat abstruse and complex could be relatively easy to construct through a gradual approach.

This study was done to define the color range, images and color characteristics of beige in fashion by analyzing the characteristics of beige that appears in contemporary fashion. In reference research, the general characteristics, the color name and range of beige was examined. In investigation research, color characteristics and images of beige that appear in contemporary fashion was defined, and it was discovered that the cases that the use of beige took more than 50% of the entire in the major collection from S/S season in 2007 to F/W season in 2010 as the subject of color analysis. The result of the study could be summarized as follows: First, the color range of beige consisted of the standard color from 2.5YR to 5YR, and color tone was pale and light gray. Second, the analysis of color beige that appear in contemporary fashion didn't show big differences according to year, season, and region. The color tones consisted of light grayish, pale, light, soft focusing colors from 5YR to 10YR. As for the arrangement of colors, it was arranged with black and it was used with the affiliation of YR, R, Y in many cases. Third, beige monochromatic image appeared soft, plain and classic. The arrangement of the image, modern, feminine, luxurious, gentle, intelligent five types were derived. Arrangements with achromatic colors were expressed in contemporary and sophisticated styles and arrangements with chromatic colors appeared to be soft, feminine and luxurious. This study draws the result to apply the fashion image of beige that was insufficient in other various color researches to design various color aspects by defining the image of beige that appears in contemporary fashion. Based on practical analysis for the color beige, it is evident that beige is an important factor and a powerful influence on fashion images.

Interference can seriously degrade the performance of GPS receiver because GPS signal has extremely low power at earth surface. This paper presents a Narrowband Interference Excision Filter (NIEF) in frequency domain that removes narrowband interferences with small signal loss. A NIEF transforms the received GPS signals with interferences into the frequency domain with FFT and then compute statistics such as mean and standard deviation to determine an excision threshold. All spectrums exceeding the threshold are removed and the remaining spectrums are restored by IFFT. A NIEF effectively can remove various and strong interferences with a simple structure. However, the signal power loss is unavoidable during FFT and IFFT. Besides the hamming window and overlap technique, a threshold-whitening technique and an adaptive detection threshold are adopted to effectively reduce the signal power loss. The performance of implemented NIEF is evaluated using real signals obtained by 12 bit GPS signal acquisition board. The output of NIEF is fed into the Software Defined Receiver to evaluate the acquisition and tracking performance. Experimental results shows that many types of interference such as single-tone CWI, AM, FM, swept CWI and multi-tones CWI are effectively mitigated with small signal power loss.

In this paper, we propose a method for the pattern inspection of LCD module using the color compensation and pattern matching. The pattern matching is generally used for the inspection method of LCD module at the industry. LCD module has many defections such as the brightness difference of the back light, the optic feature of liquid crystal, the difference of the light penetrated by driving LCD and the color difference by the lighting. The conventional method without the color compensation can not solve these defections and decreases the efficiency of inspecting LCD module. The method proposed to inspect defective badness through the pattern matching after it compensated color difference of the LCD occurred by the various causes. At first, it revises with setting by standard tone of color with the LCD pattern of the reference image. And It perform the preprocessing and pattern matching algorithm on the compensated image. In experiment, we confirmed that this algorithm is useful to detect some defections of LCD module. The proposed methods was easy to detect the faulty product.

In general, a Doppler radar can measure only the velocity of a moving target. To measure the distance of a moving target, it is necessary to use a frequency-modulated continuous wave or pulse radar. However, the latter are very complex in terms of both hardware as well as signal processing. Moreover, the requirement of wide bandwidth necessitates the use of millimeter-wave frequency bands of 24 GHz and 77 GHz. Recently, a new kind of Doppler radar using multitone frequency has been studied to sense the distance of moving targets in addition to their speed. In this study, we show that distance sensing of moving targets is possible by adjusting only the frequency of a 2.4 GHz Doppler radar with low cost phase lock loop. In particular, we show that distance can be sensed using only alternating current information without direct current offset information. The proposed technology satisfies the Korean local standard for low power radio equipment for moving target identification in the 2.4 GHz frequency band, and enables multiple long-range sensing and radio-frequency identification applications.

Environmental conditions are known to impact human health and behavior, emotions such as pleasure, anxiety, and depression, and reduce stress. Interior design that elevates emotional comfort and satisfaction can help improve mental health and well-being. This study is a systematic review that analyzed previous empirical studies that explored the effect of interior design elements on the user's emotional response which is quantitatively evaluated by bio-signal and qualitatively evaluated through self-reported questionnaire surveys. This paper aims to derive the attributes of interior design and biometric indicators that affect the user's positive emotion through the synthesis of previous studies and to confirm the feasibility of measuring bio-signals as an objective evaluation tool for architectural design and as a quantitative research method. As a result of the review, the biometric data from EEG, fMRI, ECG, EMG, GSR, and eye-tracking were used to measure the participants' emotional responses, which were manifested as positive or negative depending on certain attributes of interior design such as the form, color, lighting, material and furniture. The attributes of interior design related to the positive emotional response were the curved shape, high ceiling, openness of space, and subdued tone colors. Standard lighting conditions and wooden spaces were related to stress reduction in terms of comfort and relaxation. The free arrangement of furniture was related to the user's positive emotions. On the other hand, consistent experimental protocols could not be found, and although the sample sizes of the studies were small, the studies have demonstrated the feasibility of the emotional response measurement by using the biometric data. Therefore this method can be a useful objective tool in the measurement of human-centric data in architectural design, and to develop the evidence-based design to induce positive emotions and minimize stress.

Digital TV broadcasting's resolution or tone quality is very excellent than analog broadcasting and has many advantages including various multimedia functions such as home shopping, home banking, internet search, telecommuting, VOD, etc. In this study, it is essential to analyze the regional electromagnetic environment before Digital TV broadcasting, and therefore we analyzed Busan area's limitation using ETRI propagation model. For maintaining high-quality Digital TV signals, we measure electric field intensity wide and far in Busan including mountains area and high-rise buildings. Generally, it has lower value by a standard ETRI propagation model than simulated value about standard model, but distribution pattern are similar with it. Compared theoretical values with the measured results, they have similar values for flat area but very different values for crowded city area and mountains area So we conclude that ETRI propagation model and theoretical model are not suitable for Busan in a free space.

SULNONGTANG is a kind of “goomkok”-korean typical soup made with beef, tone and organs, and is belived to be as a good source of portein and calcium, but there is no standard formulation for that. In order to set up the standard formulation of SULNONGTANG cooking method, I have performed a nutritional analysis of change in the components of SULNONGTANG, which contained the proximate composition, free amino acids, nucleotides, cholesterol, calium, phosphorus and iron. The conventional SULNONGTANG were cooked by conventional methods varing cooking time and ingredient. And also the current Market SULNONGTANG were cooked by the same methods for conventional SULNONGTANG and adding beef's head, hooves or knee tones. The result obtained in this study were as fallows: 1. In case of conventional SULNONGTANG, the most desirable cooking time was from 12 to 18 hours, the preparation method for group A was the best to maintain the optimal amount of nutrients and 5'-IMP. 2. In Market SULNONGTANG, nutritional contents were poorer than that of conventional SULNONGTANG. When the beef's head was added to the Market SULNONGTANG, nutritional status were more desirable than those added hooves or knee bones.

The aim of this study was to measure the suprathreshold taste intensity for sucrose, NaCl, citric acid, and quinine HCl in Korean young people using a whole-mouth, sip-and-spit procedure, employing the method of magnitude matching. The results were analysed in terms of sex, taste preference, and smoker or nonsmoker. One hundred twenty three subjects (61 male and 62 female, mean age of 25.2$\pm$2.1 years) were included for the study. Subjects were instructed to give nonmodulus magnitude estimates to the intensities of five concentrations each of sucrose, NaCl, citric acid, and quinine HCl; distilled water; 6 loudness levels of a 1,000-Hz tone, using the same 9-point intensity scale. Each of the 21 taste stimuli and 6 auditory stimuli are presented in random order twice. The auditory function is used to assess the absolute intensity function of the subject's taste system. The results were as follows; 1. The perceived taste intensity for sucrose, NaCl, citric acid, and quinine HCl increased progressively as the concentrations of taste solutions were increased. Most of the subjects are standing within the zone of mean value $\pm$1standard deviation in their total perceived intensity score, and nobody is outside the limit of mean value - 2standard deviation. 2. There were not significant difference in total perceived intensities for sucrose, NaCl, citric acid, and quinine HCl between males and females. 3. There were not significant difference in total perceived intensities for sucrose, NaCl, citric acid, and quinine HCl according to the difference in taste preference. 4. There were not significant difference in total perceived intensities for sucrose, NaCl, citric acid, and quinine HCl between smokers and non-smokers in males.
