The purpose of this study was to develop the beautiful basic bodice pattern that satisfied both functionality and aesthetics on the basis of the change in the figure and length of surface body for each movement through a three-dimensional development figure of surface body for young women (aged between 18 and 24) who were very sensitive to fitness of clothes. Existing three basic bodice patterns (Yim wonja-, ESMOD-, and FIT-types) were selected and then compared and analyzed in terms of drawing methods and the wearing test was carried out by a sensory test in order to design an experimental prototype. The design of study prototype was improved by three wearing test that was correlated with low satisfactory item. And the ease was established by difference of previous direct measurement and body surface measurement.

The purpose of this study was to investigate the most appropriate arm-hole depth in 9 positions of arm movements. This subjects were four females, college students aged 18 to 23 years old. The clothing size 55 was used for this study. In the experiments for the investigation of the arm-hole depth, the evaluations were performed for aesthetic view, clothing adaptability to arm movements, and quantity of materials pulled up by 9 movements of arm. The results of this study were as follows: 1) In the aesthetic evaluation, there were no significant differences in arm-hole depths. 2) In the evaluation of clothing adaptability to arm movements, the experiment clothes, in which-arm-hole depths were raised, had more positive evaluations especially with the increasing the angle of arm movements. 3) In the evaluation of clothing adaptability to each body areas, there were no significant differences in all body areas except upper arm circumference blade. 4) In the evaluation of quantity of materials pulled up by arm movements, the clothes of B/4-2 arm-hole depth had the least amount pulled up by arm movements, which showed the highest adaptability to arm movement.

In this study, we analyzed the results of virtual clothing simulation according to the difference in the lateral neck point as well as the front and back shoulder inclination angles of the bodice foundation. Lim's (2016) (S) and Lee's (1999) method (L) were selected as the different setting for the lateral neck point. S1, S2, L1 and L2 were developed by changing the shoulder inclination angles. The SND and LND were developed by removing the darts in the S and L, respectively; in addition, the SND1, SND2, LND1, and LND2 were developed with different shoulder inclination angles. The results of S and L were similar with only slight differences observed in the armhole shape. However, the results of SND and LND were very different. The patterns of the S series were similar to each other, but the patterns of the L series were different. In addition, the patterns of the SND and LND series could not find a similar trend.

In this study, the buckling loads and mode shapes characteristic of circular and non-circular(elliptical) closed composite shells were analyzed. To analyses the buckling behaviors, we develop and report an improved generalized shell element called 4EAS-FS through a combination of enhanced assumed strain and the substitute shear strain fields. A flat shell element has been developed by combining membrane element with drilling degree-of-freedom and a plate bending element. The combined influences of length, thicknesses, cross-sectional parameters, and fiber-angle on the critical buckling loads and mode shapes of circular and non-circular(elliptical) closed shells are examined.

This study was carried out to examine the calculations including the ease amount for bodice pattern. The conclusions were as follows. The areas that were required the ease amount were the horizontal reference line, armhole depth, back & front width. According to this result the calculations including the ease amount were obtained as follows: B/2+4.1cm for horizontal reference line, B/6+6.8 cm for armhole depth, B/6+3.9 cm for the half of back width, B/6+2.3 cm for the half of front width, B/4+4.3 cm for bust point length.

In this article, we present an automated system for adjusting the 6 degree of freedom (D.O.F.) circular fixator. The system includes a scheduling software to adjust the Hexapod Circular Fixator (HCF) and an automated strut with the ability of the multiple synchronized motion and independent motion. The HCF was designed to control a 6 D.O.F. Ilizarov fixator and it's mechanism. The HCF adjustment software evaluates each value of altered length of the HCF struts to correct the complex skeletal deformity by using the X-ray data of the patient. The data of HCF adjustment software feed into the automated strut system which provides the scheduled adjustment. Then, the automated strut is synchronized by input data. Also the data of HCF adjustment software can be used to adjust HCF without automated struts. The proposed HCF system was verified by experiments.

The quantitative representation for the magnetic force of a cylindrical permanent magnet acting on a ferromagnetic cylindrical object was derived on the basis of magnetization theories, and the Gilbert and Ampere models of magnetism. The magnetic force derived in this study is directly proportional to the remanent magnetization magnetic field, the cross-sectional area of the permanent magnet, the saturation magnetic field, and the cross-sectional area of the ferromagnetic object and is inversely proportional to the square of the quantity related to the distance between the permanent magnet and the ferromagnetic object. The magnetic forces of an AlNiCoV cylindrical permanent magnet and a Ferrite cylindrical permanent magnet, both with a radius of 0.4 cm and a length of 7 cm, acting on ferromagnetic objects at distances farther than the radius were calculated to be less than 3.6711 N and 0.1857 N, respectively.

통계적 절리모델링에서 가장 불확실성이 큰 부분이 절리의 길이분포를 추정하는 것이다. 절리선 길이 분포의 추정에서 이제까지는 주로 조사선 조사(scanline survey)를 통한 절리선 반길이 분포를 이용하여 왔다. 이 연구에서는 포이송 디스크 절리모델에 대하여 보다 정밀도가 높은 절리선 길이 분포 추정방법을 찾기 위하여 조사창 조사를 이용하였다. 직사각형 및 원형 조사창에 대하여 양쪽 끝이 조사창 내부에 존재하는 절리선인 양끝내포선의 길이 분포와 한쪽 끝만이 존재하는 한끝내포선의 길이 분포를 이용, 절리선 분포를 추정하는 4개의 관계식을 각각 유도하고 컴퓨터 모의실험을 통하여 유도식의 타당성을 검증한 후 각 유도식을 이용한 절리선 분포의 추정오차를 비교하였다. 또한 절리선 분포로부터 절리직경분포를 계산하는 수치적 해를 유도하고 컴퓨터 모의시험을 통해 수치적 해에 대한 타당성을 검증하였다. 이 연구에서 제시한 조사창 조사를 이용한 절리 길이의 추정방법은 앞으로 절리모델링 분야에서 적용성이 높을 것으로 판단된다.
