The purpose of this study is twofold: First, to develop new sustainable design methods (aligned with ethnic elements and traditional culture) combined with three-dimensional digital clothing technology throughout the design process, which can be presented as guideline materials for various fashion designs to be developed in contemporary sensibilities. Second, it is the intention to produce creative fashion designs by incorporating the characteristics and methods of Miao's Huangping batik dyeing technique and to present various possibilities in the fashion design field. The overall design characteristics sought by Miao minority are in line with the complex terrain and the ecological and climatic conditions. Miaoist batik dyeing (registered as part of Chinese national intangible cultural heritage) features unique production methods and patterns. The study results are as follows. First, this attempt has enabled understanding of the national costume culture as Chinese Miao's traditional cultural heritage to be promoted, while the direction of contemporary design development using traditional elements has been presented. Second, the study demonstrated new and innovative expressions and styles relying on three-dimensional digital contouring technology and identified the possibility of developing various designs. Third, it was confirmed that the dyed batik pattern design created by the three-dimensional digital contouring technology could be recombined or expanded as digital printing to express the traditional ethnic designs in a practical manner utilizing digital printing techniques based on traditional characteristics.

Purpose - This research examined the relationship between business orientation and business goals and satisfaction of Korean-American business owners. Research design/data/methodology - Entrepreneurial Orientation (EO) and Small Business Orientation (SBO) were the theoretical constructs underlying this research. The responses from 200 Korean-American business owners who participated in the 2005 National Minority Business Owner Surveys were used for data analysis. Results - Noneconomic business goal was positively related to business owners' SBO tendency, and those with a SBO tendency had the higher business satisfaction than those with EO. Conclusions - The findings suggest that policy makers should develop business assistance programs that correspond with owners' business orientation.

c-Si wafer에 HWCVD로 증착된 a-Si:H 박막은 초기에 낮은 passivation 특성을 가지나 열처리 공정을 통해 효과적인 passivation을 가진다. 열처리 공정은 온도와 시간에 따라 큰 차이를 보인다. 이에 열선CVD를 이용하여 n type의 c-Si 기판에 a-Si:H을 증착하여 열처리 온도에 따른 Minority carrier Lifetime를 QSSPC를 통해 passivation 특성을 측정하였다. 온도는 $150^{\circ}C{\sim}270^{\circ}C$로 변화하여 측정하였다. 또한 열처리 시간을 10분씩 증가시켜 열처리 시간에 따른 passivation을 연구, 1ms에 이르는 Minority carrier lifetime을 얻었다.

The purpose of this study is to investigate the characteristics of fur and leather clothes of minority races of China in Northeas and Inner Mongolia. To examine their characteristics, the clothes and ornaments were classified into four types: headwear, clothes, footwear, and accessories. First, headwear was divided into animal head-shaped, petal-shaped, round-shaped, and cone-shaped head wear. Among them, the animal head-shaped headwear was made by making the best use of the shape of animal's head and it was used as the best disguising method when hunting. Second, clothes were composed of upper garments and lower garments. For the upper garments, Po and Jeogori were worn and pants were worn for the lower garments. The clothes were decorated with lining, applique, or top-stitching on the outer collar, neck circumference, and the edge of sleeves and pants. Third, for the footwear, high boots of leather were developed to meet the needs for a convenient life in the plains. In some areas, fur shoes and leather shoes were also used. Finally, accessories included bags and gloves. Bags were usually decorated with fur on the outside or with a fringe or applique of tanned leather. Gloves were lavishly decorated with embroideries and partly with fur or leather.

불균형 자료 문제에 대한 해결책으로 SMOTE (synthetic minority over-sampling technique)가 가장 많이 사용되고 있다. SMOTE는 유클리드 거리를 기반으로 가장 가까운 이웃을 선택한다. 그러나 유클리드 거리의 단점 중 하나는 변수들 간의 상관관계를 고려하지 않는다는 것이다. 이에 대한 대안으로 변수 간의 공분산을 고려하는 마할라노비스 거리가 제안되었다. 그러나 이상치가 존재하는 경우, 대개 마할라노비스 거리를 계산하는 데 영향을 미친다. 이 문제를 해결하기 위해 최소 공분산 행렬 MCD (minimum covariance determinant)를 사용하여 공분산 행렬을 추정하여 마할라노비스 거리를 사용한다. 이후 MCD를 활용한 마할라노비스 거리를 SMOTE에 적용하여 새로운 관측치를 생성한다. 대부분의 경우 이 방법이 불균형 자료를 분류하는 데 높은 성능 지표를 제공함을 보여주었다.

In this study, an n-ZnO/p-Si heterojunction diode with embedded Ag nanoparticles was fabricated to investigate the possible improvement of light trapping via the surface plasmon resonance effect for solar cell applications. The Ag nanoparticles were fabricated by the physical sputtering method. The acquired current-voltage curves and optical absorption spectra demonstrated that the application of Ag nanoparticles in the n-ZnO/p-Si interface increased the photo current, particularly in specific wavelength regions. The results indicate that the enhancement of the photo current was caused by the surface plasmon resonance effect generated by the Ag nanoparticles. In addition, minority carrier lifetime measurements showed that the recombination losses caused by the Ag nanoparticles were negligible. These results suggest that the embedding of Ag nanoparticles is a powerful method to improve the performance of n-ZnO/p-Si heterojunction solar cells.

고등학교 2$\sim$3학년에게 적용되는 선택중심교육과정은 교사 수급 부족으로 운영이 제대로 되지 않고 있다. 따라서 본 연구에서는 사이버교육을 통해 희소선택과목을 운영하기 위해서 필요한 콘텐츠에 대한 요구 사항을 분석하고, 그것을 바탕으로 콘텐츠를 개발하고 시범 운영하였다. 그 결과, 학생들의 진도율은 높으나 만족도는 낮게 나타났다. 이것을 해결하기 위해서는 학습 분량을 줄이고, 난이도를 낮추어야 하며, 학습 플래너와 학습 튜터와 같은 온라인 교사를 투입하여 체계적인 학습 관리와 상담이 이루어져야 한다. 아울러 학생들이 원하는 과목을 수강할 수 있도록 다양한 선택 과목을 개발해야 하며, 이를 위해서는 국가 수준에서의 희소선택교과 운영체계 구축이 필요하다.

선거는 국민의 대표를 뽑는 국가의 중요한 이벤트이다. 현재 우리나라의 선거제도는 소수의 의견이 배제될 수밖에 없는 구조적인 한계를 가지고 있고 거대 정당의 독점을 공고화시키고 있다. 이러한 상황 속에서도 직접민주주의 실험, 비례대표의 확대 등 어떤 소수의 민의라 할지라도 현실정치로부터 배제되지 않도록 대안을 제시하고 당내 민주적인 제도화를 통해 실천해가고 있는 녹색당의 활동은 의미가 있으며 선거활동은 그러한 녹색당의 지향과 실천이 발현되는 과정이었다. 일상아카이브를 지향하는 인간과기억아카이브가 선거운동 초반부터 후보 및 선거활동가들과 함께 선거활동 아카이빙을 기획하고 선거 후 어떻게 기록을 분류하여 등록하였는지 살펴봄으로써 일상에서의 정치적인 활동과 지향이 선거라는 특별한 이벤트를 만나는 접점을 일상아카이브로 포착하는 과정을 설명하였다. 지방선거와 총선거 기록은 녹색당의 활동을 증명할 뿐만 아니라 한국 사회의 정치 상황과 선거제도의 한계를 드러내는 기록이면서 그 한계를 뛰어넘으려는 소수정당의 활동을 포착한 기록이다. 녹색당 선거기록이 어떻게 민주주의의 가치를 담고 있고 소수정당에 불리한 선거제도를 자신들만의 방식으로 돌파하는 과정을 보여주고 있는지 살펴봄으로써 녹색당 선거기록 컬렉션이 한국 정치사에 갖는 의미를 살펴보았다.

The injection molding process is a process in which thermoplastic resin is heated and made into a fluid state, injected under pressure into the cavity of a mold, and then cooled in the mold to produce a product identical to the shape of the cavity of the mold. It is a process that enables mass production and complex shapes, and various factors such as resin temperature, mold temperature, injection speed, and pressure affect product quality. In the data collected at the manufacturing site, there is a lot of data related to good products, but there is little data related to defective products, resulting in serious data imbalance. In order to efficiently solve this data imbalance, undersampling, oversampling, and composite sampling are usally applied. In this study, oversampling techniques such as random oversampling (ROS), minority class oversampling (SMOTE), ADASYN(Adaptive Synthetic Sampling), etc., which amplify data of the minority class by the majority class, and complex sampling using both undersampling and oversampling, are applied. For composite sampling, SMOTE+ENN and SMOTE+Tomek were used. Artificial neural network techniques is used to predict product quality. Especially, MLP and RNN are applied as artificial neural network techniques, and optimization of various parameters for MLP and RNN is required. In this study, we proposed an SA technique that optimizes the choice of the sampling method, the ratio of minority classes for sampling method, the batch size and the number of hidden layer units for parameters of MLP and RNN. The existing sampling methods and the proposed SA method were compared using accuracy, precision, recall, and F1 Score to prove the superiority of the proposed method.
