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.

The purpose of this study is to derive and propose agenda to improve the quality of minority services provided by regional cental libraries at the present time when information gap is deepening. First, text mining and topic modeling were conducted on 144 studies in the field of library and information science that dealt with minorities, and the discussions surrounding minorities in the domestic library world were examined in detail. Next, the current status of services for minorities in Regional central libraries were examined in detail, and tasks requiring discussion were sought in planning and operation of services for minorities in Regional central libraries. To this end, interviews were conducted with practitioners, in charge of services for minorities at Regional central libraries. Specifically, 1) awareness of minorities by practitioners, 2) current status of minority services, and 3) responsibility and role of Regional central libraries for planning and operating minority services and necessary support were analyzed. Based on the analysis results, the following tasks were derived. 1) Recategorization of minority groups, 2) Establishment of reference resource, 3) Reinforcement of education, and 4) Cooperation support between regional representative libraries and local public libraries were derived and suggested.

When analyzing default predictions in real estate companies, the number of non-defaulted cases always greatly exceeds the defaulted ones, which creates the two-class imbalance problem. This lowers the ability of prediction models to distinguish the default sample. In order to avoid this sample selection bias and to improve the prediction model, this paper applies a minority sample generation approach to create new minority samples. The logistic regression, support vector machine (SVM) classification, and neural network (NN) classification use an imbalanced dataset. They were used as benchmarks with a single prediction model that used a balanced dataset corrected by the minority samples generation approach. Instead of using prediction-oriented tests and the overall accuracy, the true positive rate (TPR), the true negative rate (TNR), G-mean, and F-score are used to measure the performance of default prediction models for imbalanced dataset. In this paper, we describe an empirical experiment that used a sampling of 14 default and 315 non-default listed real estate companies in China and report that most results using single prediction models with a balanced dataset generated better results than an imbalanced dataset.

The electronic structures and magnetism of the non-oxide perovskite MgCFe$_3$(001) surface were investigated by using the all-electron full-potential linearized augmented plane wave (FLAPW) method within the generalized gradient approximation (GGA). We considered both of the MgFe terminated (MgFe-Term) and the CFe terminated (CFe-Term) surfaces. We found that the minority spin d-bands of Fe(S) of the MgFe-Term are strongly localized and Fermi level (EF) lies just below the sharp peak of the minority spin d-band of Fe(S), while the minority spin d-bands of Fe(S) of the CFe-Term are not localized much and Fermi level (E$_F$) lies in the middle of two peaks of the minority spins. The majority Fe(S) d-band width of MgFe- Term is narrower than that of the CFe-Term. It is found that the magnetic moment of Fe(S) of the MgFe- Term is 2.51 ${\mu}$$_B$, which is much larger than that of 1.97 ${\mu}$$_B$ of the CFe-Term.

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.

Climate-related events unevenly affect society, worsening mental health disparities among vulnerable populations. This paper highlights that lesbians, gays, bisexuals, transgender, queers, and other individuals identifying as sexual and gender minorities (LGBTQ+) (LGBTQ+) could be considered a climate-vulnerable population in the Philippines, one of the most climate-vulnerable countries. As such, this paper elucidated that LGBTQ+ Filipinos can be marginalized in climate response efforts due to their sexual orientation and gender minority identities. According to the minority stress theory, discrimination against LGBTQ+ individuals may predispose them to mental health problems. Thus, there is a need to institute an LGBTQ+ inclusive mental health response for climate-related events to address discrimination against LGBTQ+ individuals and uphold their mental health.

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.

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.

History education is of growing significance in relation with minority group's identity issue in an irreversible trend of globalization. Archives and the cultural institution can be a major player in the reforming the history education as conducted in Britain. This paper deals with the Moving Here project led by The National Archives. The vision of the project is to overcome barriers to the direct involvement of minority ethnic groups in recording their own history of migration and to ensure this history is passed on to the next generation through schools. More than 200,000 digitised images and documents in the Moving Here have been selected from the 28 content partners' collections. In addition, TNA and the regional partners worked with minority ethnic groups to record their culture and stories. In doing so, real and lasting relation between the community and the ethnic groups has developed. The outputs of the project such as films and stories were distributed free for regional schools. The School section of the Moving Here provides a range of education resources. One of the most impressive outcome of the project is the minority's desire to have their own archives for identity and self-esteem.
