The non-uniform distribution of contamination on insulator surface has appreciable effects on flashover voltage, and corresponding researches are valuable for the better selection of outdoor insulation. In this paper, two typical types of porcelain and glass insulators which are widely used in ac lines were taken as the research subjects, and their corrections of AC flashover voltage under non-uniform pollution were studied. Besides, their flashover characteristics under different ratio (T/B) of top to bottom surface salt deposit density (SDD) were investigated, including the analysis of flashover voltage, surface pollution layer conductivity and critical leakage current. Test results gave the modified formulas for predicting flashover voltage of the two samples, which can be directly applied in the transmission line design. Also, the analysis delivered that, the basic reason why the flashover voltage increases with the decrease of T/B, is due to the decrease of equivalent surface conductivity of the whole surface and the decrease of critical leakage current. This research will be of certain value in providing references for outdoor insulation selection, as well as in proposing more information for revealing pollution flashover mechanism.

By means of statistical analysis and module concept, this paper investigated the current situation of high school girl's uniform and put forward its improved design and database establishment. Combined with the survey data, the future design direction and trend of the high school girls' uniform were proposed. By using modular design concept, the uniform is divided into five modules, and a style database has been built. Meanwhile, the parametric pattern database has been completed by using garment CAD system, based on the style database above, which has 42,336 possibilities to assemble a pair of school uniform. Combining with digital sewing techniques and by using computerized embroidery machine, the personalized design of high school girl's summer uniform has been realized. And two simulated case have been given for examples to prove its feasibility. The idea of modular design and parametric design method proposed in this study offer references for establishing the modular design database and parametric pattern database for other types of school uniform and are of relatively high practical and theoretical value.

This study is considered about the Taekwondo(跆拳道) uniform classified by period and analyzed the current Taekwondo uniform. And founded on this contents, new designs of uniform, that a functional side are considered and can symb이ize the identity of Taekwondo, are presented through this study. Ancient times to the present time, the Taekwondo uniform classified into three types according to 'Period of putting on our nation's costume'(three kingdoms${\sim}$Joseon(朝鮮) times), 'Period of confusion on uniform'(Japan's colonial rule of Korea${\sim}$-the early 1970s), 'Period of the settlement on official uniform'(the late 1970s-the present time). And besides, the shape of our nation's costume in ancient times is succeeded until Joseon times and this basic style becomes the outset on the current Taekwondo uniform. The designed uniforms are connoted the notion of the aesthetic appreciation in Korean traditional costume, that is, a symbolic, dignified, moderate appreciation with the consideration of a functional side for Taekwondo. And the contents on the presented designs are classified into 'shape, pattern, color'. First, these designs that are adapted the shape of Baji(바지) Jeogori(저고리)-belt, which have symbolized our nation's costume, and the shape of Bacja(배자) had used in Joseon times, are connoted a 'traditional appreciation with functional side'. Second, these designs, which are adapted the patterns of the active image(a bugbear, flying horse, tiger for embroidered patches, Taegeuk(太極)) in a modern style, express a 'symbolic, dignified appreciation'. Third, these designs are well-matched a black and white color with multicolored stripes(saekddong, 색동), and its ones are connoted a 'moderate and symbolic appreciation'.

The purpose of this thesis is presenting desirable design of uniform which could reflect high school girls' demands with the researches on their consciousness of fashion and actual state of uniforms. Methods to accomplish this research include first, examinationson characteristics of high school girls and their consciousness of fashion with relevant articles, second, interviews with designers from major domestic uniform brands - ELITE, IVY, SMART - and third, analysis on related internet sites. Practical researches are followed by design analysis and proposal of improvement on high school girls' uniform, accompanied by collection of photographs from field studies, major uniform brands' shops and uniform related internet sites. Korean high school girls in the digital era are able to express themselves in each different fashion with own individuality, preference or intention, as they are particularly interested in clothes or their appearances. Their consciousness of fashion became visible in a shape of negative attitude and dissatisfaction with uniforms due to its out-of-date design, lack of features and inconvenience in action. Besides more than half of high school girls already experienced reforming it for better looks. As a result of current analysis on references of uniform designs, various levels of refinement were noticed even in uniform of similar details, design, fabric textile and color due to differences on size & length of jacket collar, dart, cutting line, size of details, decorative line, easiness in fit, length of clothes, and etc. To provide students of more refined and desired designs which reflect their demands, current uniforms are to begin acquiring delicate changes with present vogue and feature such as size of details, silhouette, cutting line, decorative line and etc. In addition newly designed uniforms are to present desirable design with image of refinement and neat as they actively comprehend students' needs within its symbolic, functional, economic and aesthetic characteristics by nature.

In in vitro cell experiments for the biological assessment of electromagnetic (EM) field, exposure system (ES) must be analyzed in terms of current density (J) and induced electric field intensity (E). Although in uniform B field, E and J in the sample medium are not distributed uniformly because of conductivity in sample dish. Thus, the precise estimation for E and J induced by uniform ELF within sample media is very important keys for successful in in vitro experiments. In this paper, we designed in vitro ELF ES with electromagnetic analysis using MATLAB simulator. Then we calculated from the measured B field to verify induced E & J distribution for random locations of cells within media in two cases of samples existence or not. ES with B field ranging from 0 to 20G consists of Helmholz coil and current generator based on the microprocessor. Also, we developed ELFES for each B field generation as uniform and non-uniform modes.

A typical HTS power transmission cable has multi-layer conductor structure to increase the current capacity. The current distribution among the conductor tapes is controlled mainly by pitches and winding directions of the layers, because the inductance of the layer is determined by the pitch and the winding direction. However, usually the current is not evenly distributed among the layers. This paper describes a method to make the current distribution more uniform and hence reduce the AC loss. If we choose a good combination we can find the optimal pitches and make an even current distribution. We studied the effect of the winding direction on a 2-layer cable by a statistical way. Calculation results and discussions will be presented.

The purpose of this study was to provide information on how to improve both the satisfaction and the current sizing system for the school uniform focused on middle and high school girls' students. For the satisfaction of their school uniform, there were statistical significance by the academic year in jacket design, blouse color, and skirt design in the case of middle school girls'. On the other hand, high school girls' evaluation of school uniform was significantly different in jacket color, jacket design, blouse color, textile of blouse, skirt color, and skirt design by the academic year. For the assessment of wearing motion, there was no significant difference by the grade in both middle school and high school girls'. However, it was shown more frequency of discomfort than that of comfort. For the evaluation of sizing fitness, the breadth of sleeve in jacket and the width of blouse were statistical significance in middle school girls' by the grade while the width of jacket, he breadth of sleeve in jacket, the length of blouse, the width of blouse and length of sleeve in blouse were different in high school students by the grade.
