This study was conducted to find out the adequate cutting method for propagation and the optimum treat-ing time of GA$_3$ to enhance the fruit setting of Pepino (Solanum muricatum AIT). Mixture of peat moss (50%) and vermiculite (50%) shows the best rooting for the Pepino stem cuttings. An active rooting was observed 15 days after the cuttings were treated with 1,000 ppm of NAA. Application of GA$_3$ at flowering stage was effective for fruit setting of Pepino and fruit setting was the most satisfactory when GA$_3$ was sprayed over the flowers.

This experiment was executed to investigate the effect of the carpenter bee as a pollinator on the fruit set increment of sweet pepper in summer hydroponics in the alpine area of Gangwon province, Korea. Where the number of fruit sets were increasing during the treatment of pollination by the carpenter bee, total yields during the whole growing period were not different. The number of seeds per fruit in the treatment of the carpenter bee increased more than that in the control by 7.3 percent increment, but the percentage of blossom-end rot increased. As fruit weight range of SS size (below 120g) decreased and that of L size (from 181g to 210g) increased by the pollination treatment, so the percentage of standardized products for the export to Japan improved. Therefore this result was effective for the fruit production of high quality for the export to Japan and it will be necessary for further study on the method of reducing blossom-end rot to be done.

As the adoption and high-performance enhancement of Electric Vehicles continue, the demand for high-output motors and high-capacity Magnetizer for producing large-scale IPMSM is increasing. The maximum peak current of the magnetization and the capacitor discharge time, which are important factors in the magnetization process, are determined by the circuit constants of the magnetizer. In this paper, we analyze the magnetizing system using MATLAB SIMULINK to design the circuit constant of the magnetizing yoke for magnetizing design and present the design procedure for Design the circuit constant. As a result, the parameters of the magnetizing yoke were derived to be 0.015[ohm] and 0.035[mH] based on the capacitance of 15,000[uF] and voltage of 5,000[V].

New type dioxygen bridged complexes of palladium were prepared by using $KO_2$ as a source of superoxide ion $(O_2^-)$. The method is completely different from the traditional one which has adopted the oxidative addition of molecular oxygen to transition metal complexes in low valency. It was suggested that the reaction to prepare the dioxygen complexes proceeded via nucleophilic displacement followed by electron transfer reaction. Five new type dioxygen complexes having ${\pi}$-allyl ligand were prepared and characterized by the application of the reaction of $O_2^-$.

정상 연구개의 근육조직에 대한 여러가지 해부학적 연구가 있어 왔지만, 구개열의 근육조직에 대한 연구는 이보다 훨씬 적었다. 또한 정상 연구개 근육조직의 형태를 잘 이해하는 것이 연구개 기능회복에 절대 필요할 것으로 사료되며 이에, 우리는 2개의 사체에서 채취한 정상상악골 및 연구개를 포함한 조직에서 연구개부위의 박리를 시행하여 근부착에 대한 해부학적 관찰을 시행하였다. 구개열환자에 있어서 연구개 근육들은 전후방적인 방향성을 가지고 있으며, 경구개 뼈의 후방 가장자리에 직접 근부착을 한다는 점에서 정상과 달랐다. 구개열 수술에 있어서 이러한 비정상적인 근부착을 박리하여 횡적방향으로 재구성하여 정중부에서 봉합하는 것이 정상적 연구개 sphincter를 만들고 연구개를 후방으로 후퇴시켜 정상적 연구개 해부구조를 재구성할 수 있는 방법이다.

본 논문은 가상 착의 시스템에 관한 것으로, 2D의류 모델 영상에서 의류 형상을 분할한 후, 분할된 의류 형상 영역의 음영 및 조명 특성을 유지하면서 사용자가 선택한 새로운 직물 패턴을 가상적으로 착용시킬 수 있는 2D 실사 기반 가상 착의 시스템의 직물 텍스쳐 매핑에 관한 것이다. 제안된 방법은 다양한 디지털 환경에서 실시간 처리가 가능하고 자연스럽고 사실적인 착용감을 제공할 뿐만 아니라 사용자의 수작업을 최대한 제거한 반자동화 처리가 가능하기 때문에 높은 실용성과 편리한 사용자 인터페이스를 제공할 수 있는 것이 특징이다. 제안된 방법에 따르면 실제 의복을 제작하지 않은 상태에서도 직물 원단의 디자인이 의복의 외관에 미치는 영향을 시뮬레이션할 수 있음에 따라 직물 디자이너의 창작활동을 도와줄 수 있고, 온라인상에서 직물 원단이나 의류를 거래할 시에 구매자의 의사결정을 지원해 B2B 또는 B2C 전자상거래 행위를 촉진할 수 있다. 더불어 기성복이나 맞춤복 모두에 대해 소비자가 자신의 취향에 어울리는 직물 패턴을 용이하게 선택하고 디자인하여 주문제작을 수행하는 거래환경을 조성할 수 있다.

본 연구에서는 식생이 활착된 식생매트 제품의 유속 저항 성능을 평가하기 위하여 식생매트의 설치 및 식생의 활착이 가능한 이동식 bed를 개발하고, 개발된 이동식 bed에서 식생매트 설치 및 식생의 활착을 완료한 후, 이동식 bed를 폭 11m 규모의 수로에 설치하여 실규모의 수리 실험을 수행하였다. 실험을 위하여 미국의 식생매트 제품의 시험방법인 ASTM D 6460을 참고하였다. 실험에 사용된 식생매트는 국내에서 통상적으로 사용되는 야자섬유 매트를 사용하였으며, 식생매트의 식생은 토심이 얕은 이동식 bed의 생육환경에서도 뿌리가 잘 발달할 수 있는 수크령을 선택하여 활착시켜 사용하였다. 실험은 봄 활착 및 가을 활착 두 가지 조건에 대하여 수행하였으며, 두 실험 조건의 결과 비교를 통하여 식생매트의 계절에 따른 식생활착 특성과 유속저항 성능 차이를 확인하였다.

This study comprehensively analyzes previous research comparing the similarities between 3D virtual and actual fittings, and identifies the current usage and limitations of virtual fitting programs. The findings reveal that, in most cases, 3D virtual fittings are not perfect substitutes for actual fittings. To address these limitations, this research focuses on the Hohenstein fitting test and BP-ANNs-based garment fit evaluation method, which incorporate various parameters, such as the correlation between wearers and garments, garment pressure, and ease, thus providing objective data, such as data acquired that can enhance subjective evaluations. By integrating such objective assessments, the study suggests potential improvements in virtual fitting accuracy. This research is expected to provide foundational data necessary for the development of a consumer virtual fitting systems alongside advancements in 3D virtual fitting technology.

This study was performed to investigate the usage and management of flavorings inside or outside (Europe, Japan, JECFA and USA) for that establish a legislation about the flavoring management in Korea. Also, this study contributed to prevent confusion when manufacturers produce flavorings used in food industry. 6,434 among 8,386 flavorings authorized by Korea Food and Drug administration are compound flavorings, and 618 among 6,434 compound flavorings are synthetic flavorings. Many other substances except for flavorings are using as solvent in flavoring manufacture. Flavorings used in food industries of Korea are listed at least one among FEMA, JECFA, CoE and JFFMA except for isooctyl acetate and tricyclene. 493 items out of total 618 synthetic flavorings have completed safety evaluation by JECFA. 106 synthetic flavorings out of the rest listed FEMA as GRAS and 20 synthetic flavorings used in Japan. The replier answered that the most frequently used flavorings are strawberry, grape, orange, plum, lemon and vanilla flavor and that the usage of flavoring added to foodstuffs is less than 0.5%.

This paper is related to a new technology allowing a user to have a 360 degree viewpoint of the virtual wearing object, and to an object VR(Virtual Reality)-based 2D virtual textile wearing system using viewpoint vector estimation and textile texture mapping. The proposed system is characterized as capable of virtually wearing a new textile pattern selected by the user to the clothing shape section segmented from multiview 2D images of clothes model for object VR, and three-dimensionally viewing its virtual wearing appearance at a 360 degree viewpoint of the object. Regardless of color or intensity of model clothes, the proposed system is possible to virtually change the textile pattern with holding the illumination and shading properties of the selected clothing shape section, and also to quickly and easily simulate, compare, and select multiple textile pattern combinations for individual styles or entire outfits. The proposed system can provide higher practicality and easy-to-use interface, as it makes real-time processing possible in various digital environment, and creates comparatively natural and realistic virtual wearing styles, and also makes semi -automatic processing possible to reduce the manual works to a minimum. According to the proposed system, it can motivate the creative activity of the designers with simulation results on the effect of textile pattern design on the appearance of clothes without manufacturing physical clothes and, as it can help the purchasers for decision-making with them, promote B2B or B2C e-commerce.
