본 연구에서는 하천 물리모니터링 결과를 바탕으로 청미천 유역의 본류에 대한 하천 수변환경을 평가하였다. 평가 지침은 수생태 건강성 평가에서 제시된 지침을 따랐다. 평가 결과, 죽산천과 청미천 합류부 지점은 2등급으로 생태서식 여건이 좋은 편으로 나타났다. 모래로 된 교호사주가 좌우안 넓은 지역에 걸쳐 형성되어 있고, 하중도 및 식생 사주도가 형성되어 식생활착이 왕성하며, 주로 달뿌리풀 위주의 군락이 형성되어 있었다. 특히 합류점 상류 본천은 자연하천의 모습을 간직하고 있었으며, 양안에는 식생과 수목이 왕성하게 자연적으로 형성되어 있었다. 화봉천과 청미천 합류부 지점에서의 수변환경 모니터링 조사 결과, 하도는 정비되어 있으나 저수로는 사행을 유지하고 있으며, 제외지의 토지이용 상태와 하천 복개율 및 횡방향 인공구조물 상태는 비교적 바람직한 것으로 나타났다. 하도 내 저수로는 호안공이 설치되지 않고 흐름의 다양성 자연스럽게 형성되어 있다. 이 지점은 하천환경이 비교적 잘 보전되어 있어, 지속적인 보전을 위한 유지관리가 요구된다. 특히 죽산천에 축산 농가 및 시가지의 확장으로 오염원이 증가되고 이들이 하천으로 유입될 우려가 있다. 생태환경을 보전하기 위한 비점오염원 유입 차단 및 수질개선 대책이 우선시되어야 할 것으로 판단되었다.

The purpose of this study was to investigate the result of a market research on men's jacket in their age of 25 to 35, who wear fitted jackets most, and to examine the comparative analysis of pattern and the wearing evaluation between classic jacket and fitted jacket. The results are as follows; Firstly, according to the results of a market research, 32.0% of the target owned fitted jackets, and 28.7% expressed their desire to buy only fitted jackets. This means their concern and preference for fitted jacket with which they could show up young, fresh and slim look are as high as those for classic jacket. Secondly, classic jacket showed the higher value than fitted jacket in such items as chest girth, waist girth, hip girth, sleeve's hem girth, jacket length, shoulder length, side seam length, and across shoulder point length. On the other hand, fitted jacket showed the higher value than classic jacket in back armhole length, front length, collar point length and sleeve's vent length. Thirdly, classic jacket was larger than fitted jacket in 1/2 chest girth(1.0cm), 1/2 waist girth(2.0cm), 1/2 hip girth(1.0cm), back width(0.5cm), front width(0.5cm) and side width(1.0cm). However, fitted jacket was higher than classic jacket in the armhole depth(0.5). Fourthly, the results of appearance evaluation revealed that there was a significant difference in 6 items. In other words, classic jacket was evaluated more appropriate than fitted jacket in such items as back width, back length, back neck depth, chest girth, waist girth and hip girth. And the fitted jacket had a higher value than the classic jacket in shoulder angle item. Fifthly, In the functional evaluation, fitted jacket was evaluated more uncomfortable than classic jacket. And this means that fitted jacket doesn't have a proper ease amount in each part and it has a high armhole depth compared to classic jacket. Therefore, for more comfortable patternmaking of fitted jackets, it would be required a pattern design which reflect men's own shoulder lines and women designers' flexibility that will satisfy both appearance and function.

This study attempted to develop a bodice prototype suitable for the 20's obese male's trunk with a BMI of 25kg/m² or more, which is distinguished from the standard body type. Through this, it was intended to provide data to help the development of clothing for obese males. Patterns such as front bodice shoulder line and front sagging were modified through primary appearance and garment pressure evaluation. Through the second evaluation, corrections such as back armhole, back waistline, and front sagging were performed. Through the third evaluation, the final pattern drafting method was developed by removing the front sagging added through the second evaluation. In the case of obese male body types in their 20s, a drafting method distinguished from the standard body type was required in the method of setting the front and back waist lines, back armhole darts, and front shoulder lines due to protruding and posture of the abdomen. This study was meaningful in that it presented a bodice prototype drafting method suitable for the 20s obese males. In the follow-up study, it is thought that actual clothing experiments and studies to develop clothing patterns by applying them to obese male tops in their 20s should be conducted.

The purpose of this paper is to develop usability evaluation tool for wearable computer. In this paper, we propose evaluation factor and object through context evaluation in the real environment. The basic idea of this process is to know the thought from wearable user. Also, we gathered the opinion from expert group. As a result, we adopted evaluation question categories. By examining some empirical data which is obtained from observation and wearability evaluation, we conclude usability evaluation of wearable computer, including smart clothing. The design process in creating a successful wearable usability is no longer about providing technical success, rather about creating a optimal user experience.

Most energy using in building part is mainly consumed for heating and cooling to meet occupancy's comfort temperature. Generally, heating energy consumption show high value than cooling energy in Korea because of high temperature difference in winter season as compared with summer in apartment building. The efforts to develope mechanical performance have been studied to reduce energy consumption in building energy field until now. However, the energy consumption in building is impacted by not only system performance but also PMV particularly at temperature and Clo value. This means that energy consumption can be changed by occupancy's comfort setting temperature in apartment building. This study investigated the passibility of overheating in apartment building by occupant' slow Clo and its setting temperature from preceding research and then the heating energy consumption by setting temperature was calculated with ESP-r. The effects of heating energy and $CO_2$ reduction are also evaluated quantitatively with Clo value. The results showed that keeping ISO-7730 standards can reduce heating energy up to 21% in compared with option 2; also, wearing underclothes with ISO-7730 standard can considerably reduce heating energy consumption up to 50%. As compared with option 2, the reduction of $CO_2$ emission for option 3 showed 0.63TCO2 of kerosene, 0.49TCO2 of LNG and 1.09TCO2 of electricity. The option 4 can be reduced by 1.48TCO2 of kerosene, 1.16TCO2 of LNG and 2.57TCO2 of electricity respectively.

This study aims at measuring and comparing the joint range of motion(ROM) of the elderly, quantitatively understanding the joint ROM and duration for their dressing and undressing of pants with 3D motion analysis equipment, and thereby providing basic data necessary for the future development of clothes carrying functional designs. The findings are as follows. As for the study method, the 9-item joint ROM measurements were conducted with goniometer, and the questionnaire analyses were carried out for t-test, ANOVA, and regression analysis with spss12.0 program. The 3D motion analyses were handled with 3D Motion Analysis Package Version 3.1 Program. The findings are as follows. First, the ROM was shown to be significantly low, as the arthritis-pain consciousness level was felt higher by the subject than the average one. Seven ROM variables, such as hip flexion, hip adduction, hip internal rotation, hip external rotation, knee flexion, ankle dorsiflexion, and ankle plantar flexion, were shown to significantly affect the discomfort level experienced at the time of dressing or undressing. Second, in the motion of inserting the remaining leg into the pant crotch part(3e), the difference of angles in the hip joint and knee joint was the largest between the women in their 20s and the elderly women with arthritis. Third.
