The purpose of this study was to understand clothing condition of elderly men focusing on somatotype variation and satisfaction with ready-to-wear and to provide basic data in designing ready-to-wrar for the elderly men. The questionnaire method was used and one-to-one interviews were held for the elderly residents in Seoul, Deajon, Jonju, and Yeosu areas. The total of 275 questionnaires (from 148 elderly men in the 60's, 99 in the 70's and 28 in the 80's) were collected and used for statistics. SAS package was used for the statistics and the statistics were based on frequency, X2-test, ANOVA, Duncan's multifle range test. The results of the study were as follows; 1) Height (p< .05), weight (p< .001) and Rohrer index (p< .05) decreased significantly with ageing 2) The somatotypes of 75.6% were changed and the 70's 8t the 80's showed significantly (p< .05) higher changing rate compared to the 60's and more changes took place significantly (p< .001) with ageing. 3) The most preferred out wear was suit & tie and next was jumper or shirt. 4) For the mode of getting suit, the highest number 55.3%) purchased ready-to-wear, next (32.0%) was tailored and the least (12.7%) neither purchased nor tailored. The percentage of buying ready-to-wear significantly (p< .01) decreased with ageing. The main reason for getting tailor-made was not well fitting of ready-to-wear (20.7% out of 32.0%). And for the mode of getting suit, there was significant differance with income (p< .001) and pocket money (p< .01). 5) The most important factors in suit and shirt werefirst, size (fitness) and second, comfort in movement. 6) For the wearing feeling of suit, 55.3% showed discomfort. There was significant difference according to the age (p< .05) and pocket money (p< .05). The Discomfort increased with ageing and less pocket money. 7) 62.4% answered it uneasy to Pick out well fitting If comfortable suit. This showed their dissatisfaction with ready-to-wear. 8) As for the items of not well fitting, 64.4% answered in jacket, 60.8% in trousers, 46.0% in shirt. The above result shows that elderly men's somatotype changes as they age, suit is found uncomfortable and it's not easy for elders to pick out comfortable ready-to-wear. So, they seem to have a certain dissatisfaction in ready to wear. Therefore, there is a need for reorganization of size and developing pattern design according to measurement of elderly men.

Distal 3D Real Object Duplication System(RODS) consists of 3D Scanner and Solid Freeform Fabrication System(SFFS). It is a device to make three-dimensional objects directly from the drawing or the scanning data. In this research, we developed an office type SFFS based on Three Dimensional Printing Process and a industrial SFFS using Dual Laser. An office type SFFS applied sliding mode control with sliding perturbation observer(SMCSPO) algorithm for control of this system. And we measured process variables about droplet diameter measurement and powder bed formation etc. through experiments. Also, in order to develop more elaborate and speedy system for large objects than existing SLS process, this study applies a new Selective Multi-Laser Sintering(SMLS) process and 3-axis dynamic Focusing Scanner for scanning large area instead of the existing $f\theta$ lens. In this process, the temperature has a great influence on sintering of the polymer. Also the laser parameters are considered like that laser beam power, scan speed, scan spacing. Now, this study is in progress to eveluate the effect of experimental parameters on the sintering process.

This study intends to reconsider pleat, which was undermined as something too simple to express the details for women's costume, by focusing on the aesthetic value of plea in men's costumes in the west before the 20th century. Furthermore, based on the aesthetic value of the pleat, diverse studies on contemporary men's costumes shall help to attempt to set up a basis for the new mode of men's costume. The pleat, a component in the costume since the ancient times, had unique characteristics including functionality, a sense of volume, directing effect that is caused by line repetitions and formativeness that results through elasticity. First, the aesthetics of the pleat before the 20th century shows rhythmic sense through the repetition of the pleat line as shown in the drape type costume, and it also shows a sense of volume as the pleat is moved along the motion of the body. Second, it shows functionality as the expansion of space moves in accordance with the motion of body sets up an internal space of the costume that facilitates body motion. Third, the pleat extends two dimension space into three dimension space using its elasticity. It exaggerates specific parts of the costume while ignoring body shape in order to symbolize status and authority of men. Fourth, it unifies the costume by wrapping the body by using quadrangle cloths with drapers, and expanding the silhouette with the pleat artificially to conceal the physical character and personality of the wearer. The physical character of the wearer disappears into the space made by the pleat. The pleat reveals the voluptuous beauty within.

In this paper. we propose an efficient method for implementing hi-directional pixel-based focusing(BiPBF) based on a sparse array imaging technique. The proposed method can improve spatial resolution and frame rate of ultrasound imaging with reduced hardware complexity by synthesizing transmit apertures with a small number of sparsely distributed subapertures. As the distance between adjacent subapertures increases, however. the image resolution tends to decrease due to the elevation of grating lobes. Such grating lobes can be eliminated in conventional synthetic aperture imaging techniques. On the contrary, grating lobes arisen from employing sparse synthetic transmit apertures can not be eliminated, which has been shown analytically in this paper. We also propose the condition and method for suppressing the grating lobes below -40dB, which is generally required in practical imaging. by placing the transmit focal depth at a near depth and properly selecting the subaperture distance in Proportion to receive aperture size. The results of both the Phantom and in vivo experiments show that the proposed method implements two-wav dynamic focusing using a smaller number of subapertures, resulting in reduced system complexity and increased frame rate.

The purpose of this study focusing on the gather decorations shown in the modern fashion was to review needlework techniques and design features of gather decorations and thereupon, analyze the aesthetic characteristics of gather decorations shown in designers' works to examine the gather decoration trend in today's fashion. First, the decorative features of gather decorations different from the conventional costumes are shirring, lace and trimming combined or shirring repeated. Second, in view of sensualism, the gather decorations seem to play a role of enhancing the exposure as a mode of expression, while the indirect exposure or beach is mixed with the materials to widen the range of gather decoration expressions. Third, in terms of history, the conventional decorative techniques are combined with new techniques and materials to create a fantastic and romantic mood different from the conventional costumes. Fourth, in view of rhythms, the wave line of the rim for gather decorations serves to express some vivid effects; on the human body, its monotonous plane repetition will turn into a new expression or a voluminous physical sense of motion. However, since expressions or meanings of the gather decorations are much diversified, they should not be regarded as simple decoration details. Our modern designers searching for new expression of creases use unique structural forms to explore the possibility of creative gather decorations. In all, since gather decorations seem to be significant as unique details conducive to a structural pragmatism and aesthetics, it is deemed necessary to continue to develop gather decorations.

Single analytical procedure including extraction, liquid chromatography, and mass spectrometric analysis was evaluated for the simultaneous measurement of lysophospholipids (LPLs). LPLs, particularly, lysophosphatidic acids (LPA) and sphingosine 1-phosphate (S1P) are lipid messengers ubiquitously found in various biological matrix. The molecular species mediate important physiological roles in association with many diseases (e.g. cancer, inflammation, and neurodegenerative disease), which emphasize the significance of the simple and reliable analytical method for biomarker discovery and molecular mechanistic understanding. Thus, we developed analytical method mainly focusing on, but not limited by those lipid species S1P and LPA using reverse phase liquid chromatography-tandem mass spectrometry (RPLC-ESI-MS-MS). Extraction method was modified based on Folch method with optimally minimal level of ionization additive (ammonium formate 10 mM and formic acid). Reverse-phase liquid-chromatography was applied for chromatographical separation in combination with negative ionization mode electrospray-coupled Orbitrap mass spectrometry. The method validation was performed on human blood plasma in a non-targeted lipid profiling manner with full-scan MS mode and data-dependent MS/MS. The proposed method presented good inter-assay precision for primary targets, S1P and LPA. Subsequent analysis of other types of LPLs identified a broad range of lysophosphatidylcholines (LPCs) and lysophosphatidyl-ethanolamines (LPEs).

Efficient power management plays a crucial role to strengthen competitiveness in the market of portable mobile commodities. This paper presents a proactive power management technique, called by Energy-Aware Scheduling policY (EASY), to exploit the sleep time information of running applications. Different from previous power management approaches focusing on power conservation in standby mode, the proposed scheme characterizes each application program's operational characteristic in active mode by observing how long the task stays in sleep state of CPU scheduler. Based on the measured sleep time, the proposed EASY speculates an adequate CPU clock frequency according to the current CPU workload and scales the frequency directly to the predicted one. Experimental results show that the proposed scheme reduces the power consumption by 10-30% on average compared to traditional DPM approach, with a minimal impact on the performance overhead.

Objectives: The objective of this study is to review the methods of combining acupoints of HANGYEOK(Cooling Mode) and YEOLGYEOK(Heating Mode) in Saam Acupuncture Method. Methods: We searched and investigated the journals and literatures by OASIS(Korea Institute of Oriental Medicine) and relevant searching engines with the key word "Saam, Hangyeok, Yeolgyeok". Unfortunately there was no relevant articles on this theme except six literatures. Six literatures with the key words relevant to Saam and acupuncture were selected and analyzed according to each composition of acupuncture prescription especially focusing on HANGYEOK and YEOLGYEOK. Results: Analyzing HANGYEOK and YEOLGYEOK of 12 meridians, two different methods emerged. In HANGYEOK to treat Heat Pattern, one method is to tonify Water points and directly sedate Fire points. The other is also to tonify Water point, but sedate Earth points instead of Fire points. It is assumed that Earth sedation method is to eradicate the underlying Fire. In only Heart meridian and Pericardium meridian there is one method to treat Heat Pattern: Water tonification and Fire Sedation. In YEOLGYEOK to treat Cold Pattern, there is one method to tonify Fire points and sedate Water points. In Pericardium meridian and Triple Energizer meridian there are some different combination of acupoints depending on literatures. Conclusions: Considering HANGYEOK and YEOLGYEOK in Saam Acupuncture Method, two methods are mainly discussed in HANGYEOK; Water Tonification Fire Sedation and Water Tonification Earth Sedation. To remove the underlying Fire, it is regarded that Water Tonification Earth Sedation is appropriate and close to Saam's thought.
