The purpose of this paper is to find how to do the width of skirt and the girth of the waist in the adequate pattern making for the obese women's skirt. Appearance test of the five experimental skirts was evaluated by the four experts in clothing construction. At the same time, 3D clothing air volume was observed for the five types of experimental skirt with different size specifications. The results from the appearance test were as follows; when the width of skirt pattern is set for(the shell girth/2), it was suggested w/4+1(front), w/4(back) for girth of the waist. On one hand, in case of (the shell girth of front)/2+(the shell girth of back)/2, it was suggested(the waist girth of front)/2 and(waist girth of back)/2 for obese women's skirt with the best appearance. As results, it was found that the width of skirt pattern for the obese women should be the greatest shell girth instead of hip girth. In the case of the hip girth, the amount of ease on hip was suggested 6cm. It was found that pattern with the wrinkle of ease was full of the gaps between body and skirt in 3D clothing air volume. In spreading out to 2D flat pattern from 3D scan data, when the width of skirt pattern was set for(the shell girth of front)/2+(the shell girth of back)/2, it was suggested(the waist girth of front/2)+(the waist girth of back/2) than the shell girth/2 in girth of the waist for the best appearance. And the conversion of 3D scan data into 2D flat pattern in curve shape of crosswise had to spread out of the plane in straight line. The obese women's clothing should be manufactured with systematical consideration of the diversity and scarcity of the obese women's body shape.

Otter boards in the trawl are the one of essential equipments for the net mouth to be spread to the horizontal direction. Its performance should be considered in the light of the spreading force to the drag and the stability of towing in the water. Up to the present, studies of the otter boards have focused mainly on the drag and lift force, but not on the stability of otter boards movement in 3 dimensional space. In this study, the otter board is regarded as a rigid body, which has six degrees of freedom motion in three dimensional coordinate system. The forces acting on the otter boards are the underwater weight, the resistance of drag and spread forces and the tension on the warps and otter pendants. The equations of forces were derived and substituted into the governing equations of 6 degrees of freedom motion, then the second order of differential equations to the otter boards were established. For the stable numerical integration of this system, Backward Euler one of implicit methods was used. From the results of the numerical calculation, graphic simulation was carried out. The simulations were conducted for 3 types of otter boards having same area with different aspect ratio(${\lambda}=0.5,\;1.0,\;1.5$). The tested gear was mid-water trawl and the towing speed was 4k't. The length of warp was 350m and all conditions were same to each otter board. The results of this study are like this; First, the otter boards of ${\lambda}=1.0$ showed the longest spread distance, and the ${\lambda}=0.5$ showed the shorted spread distance. Second, the otter boards of ${\lambda}=1.0$ and 1.5 showed the upright at the towing speed of 4k't, but the one of ${\lambda}=0.5$ heeled outside. Third, the yawing angles of three otter boards were similar after 100 seconds with the small oscillation. Fourth, it was revealed that the net height and width are affected by the characteristics of otter boards such as the lift coefficient.

도로 공사는 자연 생태계를 훼손하고, 떨어진 경관들을 긴 통로구조로 연결함으로써 외래식물의 침입 및 확산에 중요한 요인으로 고려된다. 본 연구는 도로 공사가 외래식물 조성 변화에 미치는 영향을 파악하기 위하여, 공사가 진행 중인 사업장에서 절토사면, 성토사면 및 평탄지의 지형특성에 따라 외래식물상 조사를 수행하였다. 지속적인 교란이 발생하는 사업으로써 일·이년생 외래식물에서 주로 증감이 발생하였다. 지형특성별 외래식물상 변화는 절토사면에서 감소하는 반면, 성토사면에서 증가하는 것으로 나타났으며, 평탄지는 발생장소에 따라 증감 특성이 달랐다. 이러한 외래식물상 변화의 원인은 비의도적으로 유입된 외래식물에 의해 주도되었다. 특히 성토사면에서 비의도적으로 유입되는 외래식물이 증가하는 것으로 연구되어, 성토사면이 생태계교란식물과 같은 위해성 높은 외래식물의 공급원으로 이용되지 않도록 관리하여야 한다. 반면 의도적으로 도입된 식재종들은 파종 시부터 대량 살포하기 때문에 군집을 형성하기 쉬우며 비식재지인 평탄지까지 확산하는 것을 파악할 수 있었다. 따라서, 도로공사 중이나 공사 후 도로사면 식생이 주변 생태계에 미치는 영향을 최소화되도록, 성토사면 조경계획에 지속성이 높은 고유종 식재를 환경영향평가 협의 시에 제안하는 것이 바람직하다.

Dill(Anethum graveolens L.) is a buttercup family, and flowers, leaves, stems, and seeds are all mainly used as spices. This study was carried out to discover and propagate genetic resources for the development of plant-derived medicinal fragrance materials, and to establish a database. In order to investigate the genetic characteristics of dill and to extract natural essential oils, 50 resources were parceled out the genetic resource center, sown, germinated, and then formally cultivated in the test research field. After sowing and propagation of 50 dill resources, the characteristics of each individual such as plant height, the diameter of polychasium during flowering, and the number of small inflorescences were investigated. The flowering period of dill was around May 31 to June 17, and about 10% of the proliferating population flowered around May 31. The plant length of dill was 32-14 lcm, and the length of petiole was 1~16cm, showing an average of 5cm. The color of the stem and leaf color was referred to the RHS Color chart, and the colors were classified as 44S, 19 V, and 75DI. Uses as many resources as possible with 35 resources equivalent to 19V. Inflorescences are lateral and opposite, polychasium inflorescences are somewhat flat at the upper part and have a diameter of 4.5~20cm, and divergent inflorescences are irradiated with 5~86 multiple flowers. The number of pedicels is 16-74, and the length of the pedicel is 1-18cm spread sideways or the length is different from each other.
