This study intended to suggest criteria for selection of subjects by lower body shape types necessary for evaluating slacks. For this, the characteristics were examined by lower body parts which would influence the fit of slacks on 3D human body shape data of the front and sides of the lower body for lower body shaping. The frequency of subjects by lower body shape types and the boundary points for discrimination of each type were suggested so that they could be available in selecting subjects. Using the data from Size Korea(2004), indirect measurement values measured on the front and sides of the lower body among 3D human body shape data of 175 subjects were analyzed. Their height, waist, and hip circumference fell under the range of standard deviation based on the mean of women aged 18~24 years, and then lower body shaping was conducted by combining the front and side shapes of the lower body. The front of the lower body was classified into four sections: average waist/average hip type(F1), average waist/narrow hip tyle(F2), narrow waist/narrow hip type(F3) and narrow waist/wide hip type(F4) and the sides of the lower body were divided into four sections: average abdomen/average hip type(S1), flat abdomen/average hip type(S2), average abdomen/protrude hip type(S3)and round abdomen/flat hip type(S4), and thus total 16 lower body types were created by cross analysis. Besides, discriminant analysis suggested the boundary points for each shape type of the front and sides of the lower body as a criterion for deciding lower body shape type of each subject

This research was designed to investigate and compare the characteristics of preferred clothing textiles for slacks and skirt of college students. One hundred five subjects majoring in fashion design were surveyed and the subjects selected three favorite materials among 120 samples presented in a swatch book. The subject's weighted frequencies were added tv order of preference. The results of this study were as follows: 1. In the spring and fall seasons, black twill cotton drill was preferred foremost as a textile for slacks, and medium gray basket weaved cotton pinhead with stripe pattern was preferred as a textile for skirts. 2. In summer, dark bluish gray plain linen crash was the most preferred material for slacks, and pale yellow plain linen tropical cloth was preferred for skirts. 3. In winter, olive gray cotton corduroy was the most favorite textile for slacks, and moderate brown twill wool hound check was preferred for the skirt. 4. In thickness and weight, textiles for winter were thicker and heavier than those chosen for other seasons, and textiles for skirts showed various thicknesses and weights as compared with those of slacks. 5. In fiber content, natural fibers such as cotton and wool were preferred for an seasons. 6. In the weave of textiles, twiu we,3ve was preferred for spring, fall and winter season, and plain weave was preferred for summer. 7 The most preferred colors for slacks were B and PB, and those for the skirts were YR and PB. For color characteristics, solid fabrics were generally preferred, and patterned fabrics were preferred for skirts as compared with slacks.

In this study, university students were allowed to wear the slacks varying the thigh circumference(slim/straight type) and crotch length(long, middle, short crotch type). Tightness and uncomfortability for each slacks were measured to be expressed 5point-likert type. The results can be summarized as follows: 1. At the research for measuring uncomfortability, measures of slim types and straight types of thigh circumference, crotch length B and C, and the body movement such as sitting down on the chair, sitting down with their body curling like a ball, and getting down on their knees were higher in slim types than in straight types. 2. Only crotch length C had different measures between these two types in tightness. 3. In uncomfortability, each of them had different measures among three kinds of crotch length and two types of thigh circumference had different measures among three kinds of crotch length. Four kinds of movement had different measures among three kinds of crotch length in uncomfortability. While uncomfortability of crotch length B was the highest one, that of crotch length A was the lowest one. 4. In tightness, each of them had different measures among three kinds of crotch length. While tightness of crotch length C was the highest one, that of crotch length A was the lowest one. Four kinds of movement had different measures among three kinds of crotch length in tightness.

단일 희석법을 이용한 X-선형광분광법으로 주석, 슬랙중 $Ta_2O_5$와 $Nb_2O_5$, $ZrO_2$등을 정량분석하였다. 이 방법은 표준 검정 곡선을 직선으로 되게끔 수학적으로 보정하는 것이다. 시료의 조성과 비슷한 한개의 합성표준시료와 분석시료를 무수물의 $Li_2B_4O_7$으로 묽혀서 각각 시료가 1%, 2%, 3%되게 한다. 묽힌 시료들을 $1150^{\circ}C$에서 30분간 용융하여 유리화된 구슬을 만든 다음, 곱게 갈아서, 다시 유압기로 압축하여 분석시편을 만든다. 이 시편을 사용하여 X-선 세기를 측정하고, 원소의 특성 X-선 세기에 관한 J. Scherman의 식으로부터 유도한 식에 대입하여 분석 결과를 계산했다. 이들 분석결과들을 표준검정곡선법으로 얻은 기준값과 잘 일치하며, 결과에 대한 재현성도 좋음을 보여 주었다.

This study held physical measurement for male subjects in their 20s living in Ningbo City, Zhejiang Province in China, showing the biggest market in men's clothes. Their representative lower body types with average shapes and sizes were chosen so as to develop men's slacks patterns with better dimension fitness. The following are the results of the analysis: 1. Slacks patterns were made based on the mean measurement values of 5 people, who were closest to the representative body types, from the index*absolute group of 47 people. The dimensions of application for slacks pattern-making were 77cm(omphalion waist circumference), 91cm(hip circumference), and 103cm(slacks length). 2. For the comparison of high-fitness and more-room pattern dimensions, 5 styles of slacks were made: Korean, Chinese, British, Japanese, and industrial. In the dressing fitness tests, industrial patterns had excellent appearance and Japanese ones had the best function. 3. Based on the analysis results of slacks pattern comparison, the target slacks were experimentally made and received superior evaluation points to the compared slacks patterns in two times of evaluation for appearance and function. 4. The final slacks pattern in this research had the following dimensions: front waist circumference: W(1-2cm with room included)/4-1cm, back waist circumference: W/4+1cm, front hip circumference: H(9$\sim$10cm with room included)/4-1cm, back hip circumference: H/4+1cm, crotch length: H/4-1.5cm, hip length: crotch length-H/12, front crotch extension: H/16-1.5cm, back crotch extension: H/8+3cm, knee line: 33cm below crotch line, front tuck amount: 4cm, back dart amount: 2.5cm(center) and 1.5cm(side), and back dart length: 10cm (center) and 6cm(side).

The purpose of this study was to develop slacks pattern of elderly women aged over 60s by using the virtual twin and 3D virtual garment simulation system. The results were as follows; first, By using 3D Virtual Garment Simulation, new slacks pattern considered elderly women was development. The basic numerical formula were as follows, front waist girth W/4+2+1.5, back waist girth W/4+1.5+0.5, front hip girth H/4+0.75, back hip girth H/4+1.5, front crotch extension H/16-0.5, back crotch extension H/8-1.3, front dart amount 2 and back dart amount 1.5. Second, according to the results of the new slacks pattern's appearance evaluation, it estimated more highly than existing pattern in silhouette and ease amount, confirming that new slacks pattern is appropriate for the elderly women. Also, new slacks pattern was evaluated to allow proper space length of waist, abdomen and hip. Virtual models production through 3D body scan data, pattern draft and virtual garment digital program were applied to prototypic design method so as to enhance the fitness of ready-made garments. The use of the virtual twin made it impossible to comprehend the appearances and ease correspondent to motions. In order to evaluate wearing fitness, therefore, the system should be improved so as to change arm positions and perform various motions.

석탄가스화기는 석탄가스화복합발전과 석탄간접액화 공정에서 고효율을 얻기 위한 중요한 설비 중 하나이다. 현재 여러 종류의 석탄가스화기가 성공적으로 사용되고 있지만, 간단하면서도 신뢰도를 높일 수 있는 다양한 설계 변경이 가능하다. 건식 분류층 가스화기 4종류의 형태를 제시하고 이들을 체류시간, 가스화기 출구 합성가스의 온도, 합성가스 조성을 중점으로 비교하였다. 설계개념이 적정한지를 우선 파악하고자 반응을 배제한(cold-flow) CFD 해석을 먼저 수행하였고, 실제 가스화기 조건을 반영한 화학반응이 고려된(hot-flow) 해석을 수행하여 비교하였다. 가스화기 설계에 CFD를 적용하는 데는 슬랙의 거동과 슬랙탭 설계 등 측면에서 제한적이기는 하지만, 다양한 설계개념 중에서 가능성이 높은 가스화기 형태의 범위를 좁히는 데 매우 유용하게 사용될 수 있다.
