For this study, 18 kinds of cut and sew or seamless knitted test garment were made. Samples differed from each other by skirt angles(90°, 180°), gauges(7G, 12G, 15G), and grain directions(bias direction, wale direction, and radial direction). After measuring the mechanical properties of various gauges on the seamless knitting machine, I compared shape of the knitted flare skirt through subjective evaluation on appearances. The data analysis methods used in this study were descriptive statistics, one-way ANOVA, Duncan-test, correlation analysis, and regression analysis. The subjective evaluation on appearances of knitted flare skirts showed the following: In case of 90° skirt, the seamless skirt showed a much higher score in every gauge expect that of the cut and sew 12G, and silhouette of 15G wale direction. In case of the 180° skirt, the seamless type showed a much higher score in every item over the cut and sew expect the silhouette part of 7G wale direction.

This study is focused on the elucidation of efficient and correct marking methods by comparing and analyzing marker efficiency depending on the marking job condition such as interval of checking-pattern and marker orientation using woman's Jacket and Slacks. Research Method intended to compare the marking efficiency of Jacket and Slacks, check-less and check- patterned materials with the intervals of 1.5×1.5cm and 5×5cm were selected. First, in the comparison of marking efficiency depending on check-pattern interval, regardless of the direction of marker position, single-item makers and set-item makers, the efficiency of check-less materials was higher than those of check-patterned materials and increasing the intervals decreased marking efficiency and vice versa. Marking efficiency of Slacks was less influenced than marking efficiency of Jacket by check-pattern interval. Second, in the comparison of marking efficiency depending on the direction of marker position, regardless of check-pattern interval and number of maker pieces, the efficiency of nap-up-and-down position was higher than those of nap-one-way position. Third, the marking efficiency of single-item was more effective than one of set-item in all working condition except nap-one-way position in checkless materials.

The purpose of this study was to develop the pattern-making for Korean glove. To develop the pattern-making for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over th 15 years) were interviewed on the method of glove. The results of regression analysis(hand data) were as follows (unit: cm): wrist thumb tip length = middle finger length + 3.22, hand bread = 1.25 × middle finger length + 2.18, middle finger breadth at dist = 0.23 × index finger circumference + 0.4, maximum hand circumference = 3.15 × index finger circumference + 4.13, middle finger circumference = 0.91 × index finger circumference + 0.47, maximum hand thickness = 0.69 × index finger circumference －0.02. Hand measurements for glove pattern-making were developed: There were palmar hand length, hand circumference, index finger circumference and middle finger length.

The purpose of this study was to develop the dimension of hand pattern-making for Korean glove. The glove pattern-making has difficult problem in combination of anthropometric and engineering aspects. In addition, existing dimension data are not enough for glove pattern-making. Therefore, to develop the dimension for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over the 15 years) were interviewed on the method of glove. The result of comparing between the structures in hand and existing glove pattern, there draw deduction from follows. Pattern-making for glove need size of hand length, thumb length, index finger length, middle finger length, ring finger length, hand circumference, thumb～ring finger circumference and maximum hand thickness.

유기물 탈수 공정에 적용되는 투과증발 시스템을 설계하기 위한 투과증발 시스템 모사기가 개발되었다. 모사기는 시스템 모델링 및 수치 해석 알고리즘과 관련된 simulation engine과 모사기를 Windows 환경에서 쉽게 사용할 수 있도록 한 Graphical User Interface(GUI)로 구성되었다. 모사기 구조 및 사용 방법 등을 실규모 에탄올 탈수 공정 모사를 통하여 구체적으로 설명하였으며, 모사 결과를 실제 에탄올 탈수 Pilot test에 의한 실험 결과와 비교함으로써 모사기 성능이 우수함을 입증하였다.

글루탈알데히드와 황산을 이용하여 가교된 키토산 복합막을 제조하였다. 제조된 복합막은 글루탈알데히드와 황산용액을 이용하여 표면말을 선택적으로 가교하엿다. 제조된 키토산 막에서의 키토산과 아세트산간의 착체형성의 영향을 관찰하기 위하여 수산화나트륨으로 중화하여 성능을 비교하였다. 황산으로 표면을 가교한 경우 코팅된 활성층의 투과증발에 대한 영향을 관찰하였다. 글루탈알데히드로 가교된 키토산복합막은 지지체의 종류를 변화시키면서 투과증발성능을 비교하였다. 지지체의 순수투과성능이 증가할수록 투과유량은 비슷한 값들을 유지하였으며, 선택도는 증가하다가 다시 감소하는 경향을 나타내었다. 수산화나트륨으로 키토산을 중화시킨 경우에는 선택도는 감소하였고 투과유량은 유지되는 경향을 나타내었다. 황산을 이용하여 표면을 이온가교시킨 경우 키토산 복합막은 활성충우ㅏ 두께가 증가할수록 가교시간이 증가하여야 최적의 가교조건을 나타내었다.

물/에탄올 수용액에 대한 투과증발특성을 개선하기 위하여 키토산을 이용하여 키토산/폴리비닐알콜 블렌드, 인산화 키토산 복합막을 제조하였다. 키토산과 폴리비닐알콜은 조성을 변화시키면서 블렌드를 얻을 수 있었으며, 글루탈알데히드를 이용하여 가교 방법과 조건을 변화시켜서 가교된 키토산/폴리비닐알콜 복합막을 제조하였다. 가교 농도와 가교 시간이 증가할수록 선택도는 증가하였으며 투과유량은 감소하였다. 글루탈알데히드를 가교제로서 키토산용액에 직접 첨가한 경우가 표면만을 가교한 경우보다 우수한 투과증발 성능을 나타내었다. 또한 인산화반응을 통하여 반응시간에 따라서 인산화도가 조절된 인산화 키토산을 얻었으며 이를 이용하여 인산화키토산 복합막을 제조하였다. 반응시간이 증가할수록 인함량이 증가하였으며 더불어 인산기의 도입에 따른 친수성의 증가로 선택도의 증가가 나타났다.
