The purpose of this study was to investigate the difference of the visual evaluation about gathered skirts according to different gathering conditions and objects. The experiment is made of factorial design for three variables-fabric(cotton, wool, polyester), ratio of gathers(1.5T, 2.0T, 2.5T), objects(real thing, 2D digital picture, 3D shape). Questionnaire consists of 33 sematic differential scale expressing gathered skirts' image. The subjects were 50 male and female students majoring in clothing and textile. The data were analyzed by Frequency, Factor analysis, Anova, scheffe's test. The results obtained were summarized as follows; 1. As the open-ended response there were difference among the image according to different gathering conditions and obects. 2. The image of gathered skirts was composed of 6 factors; activities, attraction, attention, softness, moderateness, function. 3. For visual evaluation of gathering conditions as different objects, there were similar as softly in fabrics and lager in ratio of gathers. 4. For visual evaluation of different objects as gathering conditions, there was more difference effect of ratio of gathers than fabrics.

Gathering is method used to control fullness along a seam line. The purpose of this study was to investigate the relationship between the quantitative research and qualitative method; the effect of gather and the types of gather drape. The experimental design consists of four factors: (l) three kinds of different weight and thickness of fabrics (2) three kinds of stitch densities (3) five kinds of ratio of gathers (4) three kinds of grain directions. Therefore one hundred thirty five (135) samples were made. And utilized SPSS WIN 10.0 Package in data analysis. The results of this study were as follows; First, after frequency analysis, side height, hem line width, node depth, node count, node width accorded with these result data recording. Second, after correlation analysis, side height related with front statements. Side height and entire visual was negative correlation. Hem line width, node depth, node count with section statements was negative correlation but node width at section statements was positive correlation. Third, after $k^2$ analysis, front picture parts getting excellent evaluation were 1st side height, 3rd hem line width, 4th node depth, 3rd node count, 3rd node width. And section illustration parts getting excellent evaluation were 4th side height, 1st hem line width, 2nd node depth, 3rd node count, 4th node width.

The purpose of this study was to identify the reasonable gathering conditions as consider of effect of gathering and variation of silhouette made by gathering conditions. The experimental design consists of four factorial design: (1) three kinds of different weight and different thickness fabrics (2) three kinds of different stitch densities (3) five kinds of different ratio of gathers (4) three kinds of different angles. Therefore one hundred thirty five (135) samples were made. Data analysis utilize SPSS WIN 10.0 Package. The results of this study were as follows: 1. In the aspect of fabrics, it is shown the visual propriety that it is as thin as the small stitch, and as thick as the big stitch. 2. As stitch densities, it shows the different stabilized nodes. 3. In the aspect of ratio of gathers, it is shown the visual propriety that a few was small stitches, which help formations of nodes, and a lot were big stitches, which help increased the effect of gather. 4. In the aspect of angle of bias, the drape appearance was excellent as a sample of cutting by 0 angle(0$^{\circ}$) of bias. The big stitches that help formations of stabilized nodes, and a case of cutting by 45 angle(45$^{\circ}$) of bias was small stitch.

This study compared the theory of a culvert spacing and analytical results of the seepage flow for the subsurface drainage. i) If culvert spacing (Sc) is within 5 m, the unit drainage (q) is very larger; in contrast, if Sc is 5 m or more, there is very little drainage in the middle between drains. Therefore, the drain spacing should be within 5 m to ensure high drainage efficiency. ii) Since the planned culvert drainage increases linearly with the soil's permeability coefficient (k), k must be taken into account when determining the drain diameter by the planned culvert drainage. iii) As a result of analyzing the drainage performance of the absorbing culvert, the drainage performance is sufficient with the diameter of the corrugated drain pipe Dc = 50 mm at the length of the drain Lc = 100 m. iv) Therefore, if the drain spacing (Sc) is less than 5 m using the low-cost non-excavated drainage pipe method (${\Phi}50mm$ the corrugated drain pipe and fiber mat) rather than the conventional trench drain method (Sc > 10 m, Dc > 100 mm), uniform and high drainage efficiency can be ensured as well as low construction cost. v) The sub-irrigation+drainage culvert requires narrower drain spacing (Sc < 2-3 m) for irrigation. As a result of examining the condition of 35 mm in diameter (Dc) and 2~3 m in drain spacing, it is possible to apply the non-excavated drainage pipe method to the sub-irrigation+drainage culvert because drainage performance is sufficient at the drain length Lc = 50 m.

거미꼬리고사리의 잡종성을 분석하기 위하여 모종으로 추정되는 꼬리고사리, 거미고사리와 함께 외부형태, 포자형태, 해부학적 형질 그리고 염색체에 관한 연구를 수행하였다. 거미꼬리고사리는 엽신이 선상 피침형으로 1회 우상분열을 하지만, 우편 기부가 중축에 넓게 붙어 거의 단엽에 가까운 형태를 띠어 거미고사리와 유사하거나 또는 도피침형이며 기부의 우편이 삼각상 피침형으로 2-3갈래져서 꼬리고사리와 유사한 특징을 동시에 가지고 있었다. 3 분류군의 포자의 표면무늬는 돌출된 날개를 형성하는 주름이 있고, 이들이 불규칙하거나 완전치 않은 망상을 형성하였다. 망상무늬의 분포양상은 꼬리고사리의 경우, 성긴 것부터 중간형까지, 거미고사리의 경우, 조밀한 것부터 중간형까지 나타난 반면, 거미꼬리고사리는 성긴 것부터 중간형 및 조밀한 것까지 모두 나타났다. 포자의 크기는 거미꼬리고사리가 평균 $54.63{\mu}m$로 $47.81{\mu}m$의 크기를 갖는 꼬리고사리와 $44.22{\mu}m$의 크기를 갖는 거미고사리보다는 큰 것으로 나타났다. 모든 분류군에서 잎의 표면세포는 파상형으로 나타났으나 꼬리고사리의 굴곡이 가장 얕았고, 거미고사리가 가장 깊었으며 거미꼬리고사리는 중간형으로 차이를 보였다. 또한 단위면적당($mm^2$) 기공의 수는 꼬리고사리가 67.00개로 가장 많았고, 거미고사리가 37.86개로 가장 적었으며, 거미꼬리고사리는 이들의 거의 중간인 45.91개로 나타나 차이를 보였다. 염색체의 수는 꼬리고사리와 거미고사리에서 2n = 72개로 나타난 반면, 거미꼬리고사리의 경우 마이산(전북)과 두륜산(전남)에서 채집된 개체에서 2n = 72개인 2배체와 불암산(서울)의 개체에서 2n = 144개인 4배체가 나타났다. 결과적으로 거미꼬리고사리는 잎의 형질, 포자의 표면무늬 및 크기, 잎의 표면세포의 형태와 기공 수 및 염색체의 변이등을 고려하였을 때 꼬리고사리와 거미고사리의 타가배수화과정을 거쳐 기원된 잡종으로 확인되었다.
