Western clothing is adjusted to the figures of the human body unlike Korean traditional clothes. For this adjustment, we need a method, known as dart, to reasonably adjust a wide circumference to curves of the human body. So far, there has been some research in the aspect of clothing engineering on how to decide darts of skirts or trousers, but no theoretical research has yet been conducted on how to decide the number and amount of dart, which has caused difficulties in beginners' understanding of dart. Futhermore, there is no consistent drawing method for the number and amount of darts in existing teaching and teaming materials. Therefore, to develop teaching and teaming methods for darts, this study identified the amount and number of darts for waist girth of 66-72cm and a hip girth of 86-102cm. When the difference between the waist girth and the hips girth, including margins, is above a minimum of 26cm, two darts can be designed, but when the difference is below 24cm, one dart is necessary. The amount of darts increases by 0.5cm for every 2cm increase of the hip girth to the waist girth. In addition, as darts become longer, the cutting of the waist line becomes smoother. For one, rather than two, darts the curve of the waist line is steeper. Based on the above results, it was assured that when belts are curved through adjustment to the waist line of skirts or slacks, their composition can be stable. Therefore, in basic teaching about slacks and skirts, the number and amount of the darts should be designed according to the difference between the girths of the waist and the hip. This difference should be a minimum of 24cm, but if it is below 24cm, the number of darts needed is one.

The purpose of this study is to use DARTs (Directed Activities Related to text) to foster inquiry problems while actively engaging accelerated gifted elementary students in the field of earth sciences. This study is continually evolving in the classroom on the proposition that accelerate the scientific thought whether inquiry problems show any change according to the extent of prior background knowledge through DARTs. Researchers appointed the accelerated gifted elementary students with 14 investigation problems and it was their duty to not only classify the inquiry problems, but to analyze using interviewing methods according to type classification framework. Many scientific terms were used concretely in the inquiry problems that were propose after DART. The students gave a direct effect to the inquiry problem to be proposed according to the level of the content that it is presented in the DARTs worksheet. As a result, the NP-IP type and the EC-IP, NC-IP inquiry problem type proposed above much as a whole in DARTs former and prior. Particularly, the EMC-IP type and etc. was variously proposed after the DARTs. And the students proposing the inquiry problem of above average proposed the inquiry problem of the EP-IP type much unlike the general average student after the DARTs. The EC-IP, NC-IP and NF-IP type were changed much after DARTs used. Particularly, the EC-IP and NC-IP type were changed much.

An anatomical and ultrastructural study on the dart sac and the dart of a Korean snail Nesiohelix samarangae was conducted to understand their morphological characteristics with the help of the light microscope and electron microscopes, TEM and SEM. Nesiolelix samarangae had two darts which are pure white structures 6-8 mm in length, tapering from 0.6-0.8 mm to 0.15-0.3 mm. The dart sac had a long conic lumen subdivided into two by a septal wall, and the darts were centrally embedded in the thick muscular layers of the sac. The darts occupied each of the two luminal spaces one per each. The convexed surfaces of the darts had many crystal buds in the shape of the petals. Otherwise, the convexed surfaces of the darts had numerous crystal buds in the shape of candle or topaz. The luminal surface of the dart sac was covered with a single columnar epithelium. The epithelial cells possessed microvilli on their free surface.

In this study, we attempted to make an original pattern of clothing for an abnormal type of figure, especially for the type of kyphosis. We measured the curvature of the spine of a woman with kyphosis with a Martin measuring instrument and a silhouetter in the following ways. First, we counted the rate of shrinkage of the standard lines drawn on the surface of the body according as the body moved. Secondly, placing the front and back darts, the front and back shoulder darts and the side darts according to“Munhwa”pattern, we made cubic cuttings of four moving postures as well as the standing one. Thirdly, we superposed the developed patterns of the standing and the moving postures, measuring the position change and the amount to the change of the darts, and compared them. The results are as follows: 1) In the developed pattern of a cubic cutting of the basic pattern and the standing posture, the neckhole became larger than that of the basic pattern, and the waist line was lowered than that of the basic pattern because the center back line was shortened due to the curved backbone.

gradient decent 를 기반으로 한 Differentiable architecture search(DARTS)는 한 번의 Architecture Search 로 모든 후보 연산 중 가장 가중치가 높은 연산 하나를 선택한다. 이 때 비슷한 종류의 연산이 가중치를 나누어 갖는 "표의 분산"이 나타나, 성능이 더 좋은 연산이 선택되지 못하는 상황이 발생한다. 본 연구에서는 이러한 상황을 막기위해 Architecture Parameter 가중치의 gradient 를 기반으로 연산들을 클러스터링 하여 그룹화 한다. 그 후 그룹별로 가중치를 합산하여 높은 가중치를 갖는 그룹만을 사용하여 한 번 더 Architecture Search 를 진행한다. 각각의 Architecture Search 는 DARTS 의 절반 epoch 만큼 이루어지며, 총 epoch 이 같으나 두번째의 Architecture Search 는 선별된 연산 그룹을 사용하므로 DARTS 에 비해 더 적은 Search Cost 가 요구된다. "표의 분산"문제를 해결하고, 2 번으로 나뉜 Architecture Search 에 따라 CIFAR 10 데이터 셋에 대해 2.46%의 에러와 0.16 GPU-days 의 탐색시간을 얻을 수 있다.

The purpose of this study is to recognize of the size conditions of ready to wear skirts and analyze the patterns of them so that some educational patterns can be complemented. For this purpose, the investigation of the size conditions was focused on the body sizes and products sizes of the care labels. The patterns of them produced through CAD have been classified into 24 items for the effective and practical analysis. Thus, 9 brands were selected and the basic skirts marketed in 2002 spring were analyzed. The results were as follows. 1. Designs of the backs of the basic skirts produced by 9 brands have the similar designs with two darts. Regarding the designs of the front, 6 brands of them have the designs with no darts, 3 of them have the one with two darts. Designs of waists are composed of low waists and round belts. 2. Regarding the waist circumference as the basic composing elements of skirts, 55.6% of the patterns have the composition of the styles with larger front than the back but 33.3% of them have the same front as back. As to the hips, 77.8% of them have the composition of the patterns with larger back than the front. As for the comparison of waist lines, 55.6% of them have lower front lines than the back lines. 3. Regarding darts placement, it was moved to the side lines from the middle of 1/2 of waist lines, dart intake was 1.8-2.4㎝, the length of the front darts was 7.8-9.5㎝, and the length of the back darts 8.4-11.1㎝ 4. The results of wearing-tests by the sensory evaluation, it showed that almost all the items of the results were satisfactory.

This research proposes a pattern design method for 24 pleated skirts in order to develop an automatic draft program for pleated skirts that will enhance fit and enable mass production. The research method and results are outlined as follow. 1. Three-dimensional body measurements were conducted on 30 randomly selected women in their 20s. By using 34 body measurement items and 6 types of calculations among the items, the items required in the designing of an original pleated skirt were extracted. They were then interpreted through correlation analysis, variance analysis, a t-test, linear regression analysis and multiple regression analysis. 2. An extra amount was added to the waist measurement and external capsule measurement according to the number of times the pleats coincided and the thickness of the fabric by the degree of polymerization of the horizontal cross section (the test of this research: 0.518mm). The extra amount of waist measurement was 3.6cm while the hip measurement was 4.3cm larger than the hip measurement combined with the external capsule measurement and the extra amount. 3. Based on the ${\pm}$standard deviation/2 as the average of the difference between the external capsule measurement and waist measurement, the subjects were classified into 3 somatotypes. Somatotype 1 presented an average total length of waist darts of 23.6cm while that of somatotype 2 was 26.2cm and that of somatotype 3 was 30.2cm. It has been confirmed that there is a significant difference among somatotypes in the total length of waist darts from the front center to the front side and the total length of waist darts from the side to the back center in terms of the average amount of waist darts for every 12 parts on the WL.

The results are as follows: 1) In the developed pattern of a cubic cutting of the basic pattern and the standing posture, the neckhole became larger than that of the basic pattern, and the waist line was lowered than that of the basic pattern because the center back line was shortened due to the curved backbone. 2) As for the change of the standard line according to the movement, we found that the waist line, the center front line, the center back line, the bust width line, the upper back width line and the back width line became longer. Special consideration must be given to the function of the clothing for an abnormal type of figure. 3) The difference of the measurements between the cubic cutting and the body measurement regardless of the body movement is due to a gap by an acute angle at the jutted place between the developed pattern and the body surface. We found that the body measurement of the upper back width line, the back width line and the bust line became larger. Consequently, in making an original clothing pattern, it is desirable that we must not place the front and the back waist darts at the jutted place on the back from the functional and the aesthetic viewpoint of clothing. It is also desirable that we must widen the neckhole because the shoulder angle is close to a straight line due to a jut of the upper back width line.
