The purpose of this study was to analyze the cases of IMF Managing Director Christine Lagarde to discuss power dressing characteristics represented in the fashion style of women political leaders. Study methods included literature reviews on the theoretical background of Christine Lagarde's Political Leadership formation and the power dressing of women political leaders. The results of the study were as follows. First, governor Christine Lagarde's fashion styles worn at formal events were summarized into suits, bags, scarves and jewelry. Clothing type was found to be 98% suits, 5% dress with the colors black, gray and white being worn the most, 84% were achromatic, blue tones and vivid tones were about 16%. Faborite accessories included scarves, jewelry and luxury bags. Scarves were higher frequency utilization at 51% of the total wear. Second, characteristics of power-dressing appearring as fashion styles were summarized as wealthy, honorable, having political power, being, charismatic or, feminine. Luxury suite luxury brands holds a sense of power with many believing they wealth, honor and charisma. Luxury bags, V-zone ornaments of scarves and, jewelry are items of power that people often wear in order to charisma and a symbol of power. They are also, used as an important element in portraying confidence and leadership as IMF governors.

In surface grinding, the conditions of the grinding wheel has much more significant effect on the machined workpiece as compared to other metal removal processes. The contact between the grinding wheel and the workpiece introduce heat and resistance, which restrict the self-dressing of the grits and result in burrs cracks on the workpiece. Therefore, before or during the grinding operation, it is necessary to self-dressing the grinding wheel for more accurate performance. In general, however, the choice of the dressing time has made by the operator's own decision or the condition of the workpiece. In this paper, a new method for finding the optimal dressing time of the grinding wheel is proposed. In order to develop a more sophisticated methodology, a non-contacting in-process optical measurement method using a laser beam has been introduced to find the glazing, loading, and spilling of the grinding wheel Simultaneously, a three-dimensional computer simulation of the grinding operation has been attempted based on the contact mechanism between the grinding wheel and the workpiece. The grains of the grinding wheel are simulated and the optimal dressing time is determined based on the amount of grain wear and work surface roughness.

이 연구는 기능성 사료용 보리의 생산 기술을 개발하기 위한 기초자료를 얻고자 식물체 전체에 안토시아닌이 함유된 겉보리인 '보안찰보리' 품종을 이용하여 전년에 구명된 안토시아닌의 축적을 높이기 위한 최적 추비 및 수확시기를 구명한데 (Song et al., 2011) 이어 최적 시비량과 생산성, 사료가치 및 부위별 축적정도를 검토하였다. 그 결과 질소 추비량이 증가함에 따라 출수기가 지연되었고, 초장은 80% 증비구에서 가장 컸으며, 건물율은 유의적으로 감소하였다 (p<0.05). 생초수량은 증가되는 경향이었으나 통계적인 유의성은 없었고, 건물수량과 TDN 수량은 처리구간에 차이가 없었다. 조단백질 함량은 부위별로 이삭 > 총체 > 잎 줄기 순으로 높았으며 (p<0.05), 질소 추비량의 증가에 따라 모든 부위에서 유의적으로 증가하였다 (p<0.05). NDF와 ADF는 부위별로 잎 줄기 > 총체 > 이삭 순으로 높았으며 (p<0.05), 질소 추비량의 증가에 따라 잎 줄기에서는 감소하였고, 총체와 이삭은 처리구간에 차이가 없었다. TDN 함량은 이삭 > 총체 > 잎 줄기 순으로 높았으며 (p<0.05), 질소 추비량의 증가에 따라 잎 줄기는 증가하였고 (p<0.05), 총체와 이삭은 처리구간에 차이가 없었다. 안토시아닌 함량은 부위별로 잎 줄기 > 총체 > 이삭 순으로 높았으며 (p<0.05), 질소 추비량의 증가에 따라 잎 줄기와 총체에서 유의적으로 감소하였다 (p<0.05). 특히 cyanidin-3-glucoside (C3G), delphinidin (Del), malvidin-3-glucoside (M3G), malvidin (Mal)의 감소가 가장 현저하였다 (p<0.05). 이상의 결론을 종합하여 볼 때, 이 연구에 이용된 '보안찰보리'는 잎 줄기에 안토시아닌 축적이 가장 많고, 조사료 수량을 고려하면서 안토시아닌 함량이 높은 조사료용 유색보리를 생산하기 위해서는 월동 후 생육재생기에 표준 추비량을 주는 것이 가장 유리한 것으로 판단되었다.

Silk protein has been investigated by many researchers to apply to biomedical field. We reviewed biomedical applications of silk protein such as matrix of wound dressing and drug delivery system. Since silk fibroin/ poly (ethylene glycol) (PEG) semi-interpenetrating polymer networks showed good mechanical properties and wound healing phenomena, it can be used as wound dressing materials. Sericin nanoparticles pre- pared by conjugation with PEG and silk protein/ poloxamer mixture gel are expected to become a deliv- ery as matrix for hydrophobic drug.

A new dressing technique with utilizes electrolytic phenomenon for realizing effective mirror surface grindings with metal bonded super-abrasive wheels is called “Electrolytic In-process Dressing Grinding”. This technique enabled metal bonded micro-grain wheels, such as micro-grain cast iron fiber bonded wheels, to be used for mirror surface finish processes effectively. But this technique requires a lot of knowledge and experience to perform. And the condition of dressing is variable according to the time. Therefore adaptation of Monitoring and Control technique is needed.

The puropose of this study was to investigate the relationships between four aspects of clothing behavior ana marital adjustment. Marital adjustment was measured with the Spaniel's Marital Adjustment Scale. The questionnaire measuring clothing behavior consisted of items designed to assess dressing for self, dressing for others, self-concept regarding clothing and dependence in clothing. This questionnaire was selected and revised from inventories of such researchers as Pasnak, Sin, Lee, Park and Creekmore. This questionnaire was administered to 269 home makers in Seoul. Statistical analyses utilized in this study included correlation coefficients and $X^2$ test. The results were as followes: 1. Marital adjustment showed significant and positive relationships with dressing for self, dressing for others, ana self-concept regarding clothing. 2. Marital adjustment was negatively correlated to dependence in clothing.

Ferrite is widely used in the material of magnetic head, but is difficult of grinding because of their brittleness and hardness. Therefore, diamond wheel with superabrasive is required for surface grinding of this brittle material. But the conventional dressing method can not apply to the diamond wheel with superabrasive. In this study describes a newly proposed method for carrying out effective inprocess dressing of diamond wheel with superabrasive. Using the IEDD the surface roughness of workpiece was improved and grinding force was very low. Resently IEDD is good method to obtain the efficiency grinding and surface grinding of brittle materials.
