The purpose of the study, approaching from the aspect of the construction technologies, is to determine the architectural techniques of traditional wood architects in existence, through which the systems and techniques that create the inherent characteristics of Korean Architecture are clarified. With understanding traditional construction system and focusing on the fact that built environment results from the consistent standards and technologies of architects, this study inquires into the systematic standard and its formation that present in the process of planning for the overall scale and shape of a building from the following (four) perspectives. The study determines the characteristics of '間(Kan)' (unit; fundamental unit that measures Korean traditional houses) and the methods of columns disposition of which the '間 (Kan)' is made up. Once the necessary spaces are decided according to the size of a building, then floor plans are drawn with the standard unit, '間(Kan)'. The '間(Kan)', as a modular unit, is not only composing the floor plans, but also functioning as an Area unit, Space unit and Structural unit. Composition of '間(Kan)' varies with disposition of columns, and therefore multiform of floor and spaces are created. In this study, the '間(Kan)', as a standard unit, is used in the form of specific size and area, and it is demonstrated how the floor plans are developed by organizing the columns in accordance with the spaces requested.

The purpose of this study is to set the standard items of the garment size for infants. The studied subject consisted of 560 infants from at brith to 12 months of Pusan and Gyeongnam area. The Results from this analysis are as follows; 1. The most significant growths in body dimensions of infants as an month age advanced. Expecially, stature, weight and the items of height and length showed a quite rapid growth, but the items of girth, breadth and depth showed a slow growth. 2. The coefficient of correlation between stature and weight shows high value. The result of interpretation of the extracted components are as follows. It will be more appropriate to use the method of parallerizing with height and weight items rather than with month age in classficating and indicating of size for infant garment and in taking the head girth as basic item of infant for head-gears. Consequently, as the standard items for the classification of clothing constuction of infants, it is advisable to select weight alone or both stature and weight. 3. According to the method of classifying the somatotype by the index of body soundness, the Rohrer.Kaup index on the basis of standard items, weight and stature was divided into somatotype.

Reflecting the consumer's desire to look young, the "down-aging" trend, which blurs the distinctions between age groups, is the latest craze in the fashion market. The popularity of this trend made brand identities similar, resulting in customers becoming more interested in segmented notions of fashion (in terms of the story, design, high-quality material, etc.) regarding the product, and in particular, focus has become oriented to the fitness to the human body. In this sense, the researcher aimed to develop the prototype of a slim-fit tailored jacket that fits the standard somatotypes of women in their 30s well. For the purpose of this research, slim-fit tailored jackets from existing brands were collected and analyzed, and a subsequent wearability test was conducted based on the standard somatotype of women in their 30s. The research patterns were prototype of the developed slim fit tailored jacket are bust size of 3.8 cm, waist of 7 cm, and hip size of 3.8 cm. Then the research patterns were selected to develop the prototype of a properly fitting slim-fit tailored jacket. As outlined above, the development of a slim-fit tailored jacket prototype for the standard somatotypes of women in their 30s was conducted by solving the fitness issues of existing brands in order to produce properly fitting jackets that satisfy consumers.

Continuous synthesis process for monodispersed zirconia powders with ultrasonic wave mixing was developed. Reactant solutions were flowed through a T-tube with small diameter and then mixed in a microscale with ultrasonification. Reaction and aging were followed during the mixed solution of reactants is in plug flowing through a narrow long teflon tubing. Zr(n-OC4H9)4 in ethanol and H2O in ethanol were used as reactants. From this process monodispersed, spherical, non-agglomerated, singlet hydrated zirconia powders with 0.6 $\mu\textrm{m}$ average size were obtained. Geometrical standard deviation of the particle size distribution was less than 1.2 with ultrasonic mixing, and the geometrical standard deviation was not affected by the flow rate of the reactants.

The purpose of the study was to suggest ways of improvement of the present sizing systems for the middle aged women's clothing. For this, a questionnaire survey for the aged group and calculating coverage rate of one garment item(suit) between the companies has been carried out. The data was analyzed with use of SPSS package. The statistics were based o frequency, X2-test, t-test and one-way ANOVA. The results of the study was as follows: 1. In case of survey for middle aged women, the problems concerning the length and abdominal girth were found, that is to say, the former too long and the latter too tight. 2. The sizing systems between companies were very different in size classification and standard deviation of each sizes. 3. In calculating coverage rate of the 10 companies's sizing systems, coverage rate of the smallest size in each were the highest and those of the biggest were 0%. It means the standard deviation of the present sizing systems are not enough to cover the various body form of the middle aged women, so that the more diverse sizing system is required for the better fitness of middle aged women's clothing.

The pressure fluctuations in a gas-solid fluidized bed has been analysed using s statistical method interpreting fluidized 냥d behavior. The performing statistical a analysis of the pressure fluctuations in a fluidized bed of 6.7cm-ID. using uniform p particle size of 115 to $1015{\mu}m$ in diameter. The fluidized gas used air(velocity 0.1~1.2m/sec) at settled bed height to diameter ratios which is LlD=l.O. Then, the pressure fluctuations measured by DPT(differantial pressure transducer). The measuring characteristic values of pressure fluctuation were the mean value and standard value, and also, it has been found that the standard deviation of the pressure fluctuations can be effectively used to predict minimum fluidizing velocity and to explain the fluidized phenomena.

In this paper, we investigate the performance comparisons of various turbo interleavers which are adopted as a standard such as IMT-2000 and satellite DVB(digital video broadcasting). The bit error rate performance is calculated by the fixed point computer simulations over Rayleigh fading channels. For a fair comparison, the simulation is performed on the basis of equal the interleaver size as we can. From the results, it is shown that the turbo interleaver in W-CDMA outperforms the turbo interleavers in CDMA2000 and satellite DVB. The performance gains are even larger as the interleaver size is increased.

This paper presents splitting and merging algorithm based on adaptive thresholding. The algorithm first divides the image into blocks, and then compares each block using the calculated thresholding value. The blocks which are same are merged using the certain threshold value and different blocks are split unless it satisfies the threshold value. When the block has been merged, maximum and minimum block sizes are determined then the average block size is determined. After the average block size is determined the average intensity and standard deviation of average block is calculated. The process of thresholding is applied to binarize the image. Finally, the experimental results show that the proposed method distinguishes clearly the background with text in the document image.

The incomplete penetration(IP) discontinuity in butt joint weld, which is detected during safety analysis of the steel bridge by nondestructive evaluation(NDE) method, is classified as unacceptable defect according to the NDE codes and standards. In fact, there are a little allowance in butt joint weld in the view point of design criterion, and also detected IP discontinuity should be classified and evaluated for the fatigue strength and residual life estimation. In this study, we performed fatigue test to evaluate the fatigue strength of high strength steel(SWS490A) containing IP discontinuities in various size, the results compared and classified according to the bridge construction standard specification which published by korea administration of construction and traffic. Experimental results could be used to evaluate and estimate the IP discontinuities considering different stress range in butt joint bridge weld during periodic safety inspection.

My questionaire survey revealed that even those experts that engage in architectural design did not precisely understand much of the regulations concerning ground-level. In terms of restricting the size of the building area, the generous policy of excluding balconies and basements from the calculation of building size actually causes problems. As far as the right to sunshine is concerned, the weighted average ground-level is determined to be the ground-level standard of the neighboring plot when the neighboring plot is a sloping bare ground. When the difference of heights is over 3 meters, it would be appropriate to assess the weighted ground-level standard every 3 meters.
