This study aims to develop contemporary fashion designs from the unique Yao minority costumes and to explore the possibility of developing creative designs by using knitting materials. The research method is based on the cultural clothing and costumes of the Chinese ethnic minority, as well as literature concerning the Yao costumes and photo data to investigate the cultural background and characteristics apparent in Yao costumes. The overall design characteristics of Yao costumes are as follows. First, the shape of Yao costumes are divided into straight-lined short tops with pleated skirts or shorts, or cardigan tops with pants and aprons, or long shirts, pants, and a belt. Each variant of tribal clothing is different. Second, the colors used are mainly black or dark blue, and these are accented by other colors, such as red, orange, yellow, green, blue, and white. Third, the clothing patterns are mainly in plant, animal, natural, geometric, and human, etc. motifs. The most common patterns in daily life are the patterns using geometric shapes, plants, or animals. Using the background of the unique lifestyles of the Yao ethnic minority, this study applied hand knitting and jacquard techniques for a knit fashion design. In order to develop traditional patterns, Yao patterns were entered into an Illustrator and SDS-ONE APEX3-4 was used for simulation. Using wool fibers as the raw material; the knitting machine used a Bird's eye Jacquard technique-10GG. The results of this research and design work were as follows. First, the knitted clothing design using Yao clothing elements has significance for the development and flexible use of ethnic elements in contemporary creative design. Second, the straight cut design using hand-knitted and jacquard-knit fabrics can minimize waste materials and provide more possibilities for sustainable design development. Third, it provides additional methods for the combination of hand-knitting and jacquard knitting fashion design.

The BCBJ (Back Contact and Back Junction) or back-lit solar cell design eliminates shading loss by placing the pn junction and metal electrode contacts all on one side that faces away from the sun. However, as the electron-hole generation sites now are located very far from the pn junction, loss by minority-carrier recombination can be a significant issue. Utilizing Medici, a 2-dimensional semiconductor device simulation tool, the interdependency between the substrate thickness and the minority-carrier recombination lifetime was studied in terms of how these factors affect the solar cell power output. Qualitatively speaking, the results indicate that a very high quality substrate with a long recombination lifetime is needed to maintain the maximum power generation. The quantitative value of the recombination lifetime of minority-carriers, i.e., electrons in p-type substrates, required in the BCBJ cell is about one order of magnitude longer than that in the front-lit cell, i.e., $5{\times}10^{-4}sec$ vs. $5{\times}10^{-5}sec$. Regardless of substrate thickness up to $150{\mu}m$, the power output in the BCBJ cell stays at nearly the maximum value of about $1.8{\times}10^{-2}W{\cdot}cm^{-2}$, or $18mW{\cdot}cm^{-2}$, as long as the recombination lifetime is $5{\times}10^{-4}s$ or longer. The output power, however, declines steeply to as low as $10mW{\cdot}cm^{-2}$ when the recombination lifetime becomes significantly shorter than $5{\times}10^{-4}sec$. Substrate thinning is found to be not as effective as in the front-lit case in stemming the decline in the output power. In view of these results, for BCBJ applications, the substrate needs to be only mono-crystalline Si of very high quality. This bars the use of poly-crystalline Si, which is gaining wider acceptance in standard front-lit solar cells.

This study made fundamental approaches on the significance of social enterprises on minority protection policies. In particular, it offered discussions focused on the relationship between social enterprises and North Korean defectors which greatly affect minority policies. Study results can be summed up as follows. First, the greatest difficulties for North Korean defectors in their adjustment to Korean society are economic activities and a sense of social differences and social enterprises are a policy which can resolve these problems in the most effective way. Second, existing social enterprises were excessively run by the central government and they were support models which lacked creativity and development. To resolve such problems, a lesson was learned that these must change into policy models with local coproduction. Third, a lesson was learned that social enterprises offer more than simple economic activity, offering the proper functions of society, culture, living, and language, and thus the participation of North Korean defectors in social enterprises should be made mandatory in certain sectors. Such research results will contribute to theoretically explaining the relationship between North Korean defectors and social enterprises as minority policies.

There have been frequent reorganizations of administrative areas and place-names in China since 1949. These reorganizations were practiced with the two institutions 'city control over surrounding counties(shiguanxianzhi)' and 'county transform to city(shigaixian)' based on the socialist commodity supply system(gongxiaozhidu) and civil registration system(hukouzhidu). In this article I will try to discuss the influence and meaning of these reorganizations on the minority nationalities districts in frontier China. The Conclusions are as follows: The increase of the number of cities and the reorganization of the place-names in the minority nationalities districts is not the result of the increase of population or advancement of industrial structure but the result of Han people having non agriculture registration(feinongyehukou) population's increase. Therefore the reorganizations of administrative areas and place-names was a process of inclusion of the minority nationalities areas as a part of the Chinese territory(guotu) more perfective than before.

The purpose of this thesis was to investigate the similarities between religious costumes and Kazakh and Tajik minority women's costumes in the Chinese northwestern minority population that believes in both Islam and Shamanism. The research was conducted by investigating the forms, colors, and patterns of 240 representative costume pieces and making quantitative comparisons between religious and traditional costumes. The results showed that the Kazakh and Tajik costumes were similarly formed, both intended to cover the human body. Both the Islamic and traditional headdresses were also similarly shaped. In terms of color, black, white, green, and blue were found frequently in the Islamic religious costumes, as were red and yellow. Red, white, and brown, ascribed to the colors of shamanism, signifying incantations, were also frequent, indicating that this was engrained in their lives. A review of the traditional costumes revealed the patterns of Islam. Plants, geometry, abstraction, and letter patterns were dominant, whereas the meaning of the Islamic patterns, rebirth, sun, life, and hope, influenced the traditional costume patterns. Patterns associated with incantations, like the animal horns shown in the shamanism religious costumes, were persistently observed even after the people were converted to Islam. This study on the similarities between religious and traditional costumes in the Chinese minority might help us understand the connection between religious and traditional costumes and elucidate the cultural costume transition process.

This treatise studies on how ideology and value of Chinese minority race undergo change according to social, political transition that the Chinese minority race has experienced for a long time and I also have tried to elucidate how these kinds of their experiences have been effected upon their own life, even it is part of my basic subjects for my study. Hence I would give weigh to focus on contemplating process of the past and the present rather than predictive discussion of how their pursuing value will be transformed. For my ebullient study, I'm willing to make Yi-Zu's moral culture become axis of my treatise, and capitalize on not only how Han-Zu's ideological philosopies have been disseminated, but also how acculturation have been taken place in Yi-Zu's moral culture system. Yi-Zu has the longest history and the greatest their own population, even the largest residence of various Chinese minority races. And Yun-Nan is the historical place where not only various Chinese minority races have lived, but also acculturation between Chinese majority, Han-Zu and them have been begotten. Above all, I would delve into traditional religion to understand Yi-Zu's moral culture as was already mentioned that it is my axis of treatise. Furthermore, I deliberated on how Taoism have been infiltrated Yi-Zu's moral culture, also how Han-Zu's ideological philosophies have been permeated Yi-Zu's, and what is more how to help themselves still remained in Yi-Zu's. Through my such these efforts, I analyze the aspect of embracing of Han-Zu's moral culture by Yi-Zu's and some facts of vicissitudes about it.

Autophagy is a self-digestion process, wrapping cytoplasmic proteins or organelles to form vesicles for degradation in lysosomes. The process plays an important role in the maintenance of intracellular homostasis. Here we overview articles on autophagy and cancer/tumors in Pubmed and found 327 articles. Autophagy exists in many tumors and is involved in cell malignant transformation and tumor cell growth. In early phases of tumorigenesis, autophagy clears the abnormally folded proteins and dysfunctional organelles such as mitochondria. Autophagy can also inhibit cell stress responses and prevent genetic damage. When a tumor develops, autophagy helps tumor cells survive nutritional deficiencies and hypoxic conditions. Studies of autophagy in the occurrence and progression of tumors should provide new therapeutic strategies for tumors.

This study aims to prove that the fact that minority races in the north-eastern region contributed sable skin to the Quing Dynasty might be related to Cho-Sun of King Muryong in the Warring states period because documents are available here and there. The Chinese had been using fur clothing since ancient times but we cannot find any mention that they had used sable skin. This fact shows that sable skin was not widely used because of its rarity. Cho-pi had been used in making costume on a large scale from the period of the Han Dynasty to the end of the Quing Dynasty. Cho-pi was very rare and it was used as a measure of bartering. China met the demand of cho-pi by the Cho-pi contributions of the frontier minority races. It might bwe that the high demand of Cho-pi in the Quing Dynasty forced minority races to contribute Cho-pi The documents concerning Cho-pi in the north-eastern region are of great importance not only to the history of costume but also to the history of ancient economy and national culture.

This paper suggests heuristic algorithm with polynomial time complexity for rigging elections problem that can be obtain the optimal solution using linear programming. The proposed algorithm transforms the given problem into adjacency graph. Then, we divide vertices V into two set W and D. The set W contains majority distinct and the set D contains minority area. This algorithm applies divide-and-conquer method that the minority area D is include into majority distinct W. While this algorithm using simple rule, that can be obtains the optimal solution equal to linear programing for experimental data. This paper shows polynomial time solution finding rule potential in rigging elections problem.

Among the various possible factors affecting the Minority Carrier Life Time (MCLT) of the mc-Si crystal, dislocations formed during the cooling period after solidification were found to be a major element. It was confirmed that other defects such as grain boundary or twin boundary were not determinative defects affecting the MCLT because most of these defects seemed to be formed during the solidification period. With a measurement of total thickness variation (TTV) and bow of the silicon wafers, it was found that residual stress remaining in the mc-Si crystal might be another major factor affecting the MCLT. Thus, it is expected that better quality of mc-Si can be grown when the cooling process right after solidification is carried out as slow as possible.
