Numerical calculations have been made about the phase differences of the short circuit current in a solar cell according to the variation of the modulation frequency. The phase differences in short circuit current of the solar cell exposed to the modulated light source is measured experimentally. From the above two results, the minority carrier lifetime has been determined. Also, minority carrier lifetime has been determined from the observed photo-induced open circuit voltage decay wave form that follows termination of the excitation.

We investigated the effect of mechanical back side damage in viewpoint of electrical and surface morphological characteristics in Czochralski silicon wafer. The intensity of mechanical damage was evaluated by minority carrier recombination lifetime by laser excitation/microwave reflection photoconductance decay technique, atomic force microscope, optical microscope, wet oxidation/preferential etching methods. The data indicate that the higher the mechanical damage degree, the lower the minority carrier lifetime, and surface roughness, damage depth and density of oxidation induced stacking fault increased proportionally.

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.

In this paper, we analyse empirically the relations between ownership structure and cash holdings of firms listed on Korea Securities Market and Kosdaq Market of Korea Exchange. The main results of this study can be summarized as follows. Cash holdings increase as large shareholder's equity holdings increase. Cash holdings increase as the difference between first largest shareholder's and second largest shareholder's equity holdings increase, and cash holdings increase as the ownership concentration increase. Managerial ownership exert a non-linear effects on cash holdings. So to speak, at lower level of managerial ownership, managers hold more cash to pursue their own interests at the expense of minority shareholders, but at higher level of managerial ownership, the interests of managers and shareholders are aligned, and also at highest level of managerial ownership, managers hold more cash to pursue their own interests at the expense of minority shareholders. Cash holdings increase larger in owner-controlled firm than in management-controlled firm. These results support the expropriation of minority shareholders hypothesis that large shareholders can extract private benefits from corporate resources under their control at the expense of minority shareholders. This paper contributes to defining information value of large shareholder's equity holdings on cash holdings for a firms' other stakeholders such as investors and creditors, and to strengthening a legal and institutional safeguard for external minority shareholders. Ownership concentration might have negatively affected the evolution of the legal and institutional frameworks for corporate governance and the manner in which economic activity is conducted. It could be a formidable barrier to future policy reform.

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.

This paper focuses on a sociologic approach, the theory of planned behavior (Ajzen 1991) and a sociolinguistic field, the language shift (Fishman 1991, Crystal 2000). It describes the theoretical background of language shift and briefly mentions the history of Hungarian language and Romanian language contacts. After presenting language use of the Hungarian minority students and explaining the theory of planned behavior, it turns to apply the theory of planned behavior to the language shift from the view of bilingual speaker(s). This paper wants to propose the application of the theory of planned behavior in language shift and open new perspective in bilingual research.

The purpose of this study is to examine the types and characteristics of Chinese indigo dyed designs performed until today in private houses of Chinese minority races and to examine the modern value of traditional dyeing crafts of minority races by investigating the cases of utilizing modern private Chinese indigo dyed designs. As the research methodology for theoretical study about the history of Chinese traditional pattern dyeing, the origin, types and characteristics of Chinese indigo dyed designs, the preceding research data, photo data, and Internet data were utilized, and for the empirical research on Chinese traditional dyeing techniques and the cases of utilizing today Chinese indigo dyed designs, the on-site survey on Guizhou and Yunnan was conducted during February and March 2008 and the data were collected and analyzed. Based on the results of this research, it was found that Chinese indigo dyed designs represented Chinese traditional pattern dyeing, which was inherited and developed mainly in Chinese minority races and Chinese. It could be seen that according to geographical distribution and characteristics of each race, the types and characteristics of dyeing techniques were formed, which are classified into the batik of the Miao of Guizhou in the Chinese southwestern region, the tie-dyeing of Bai of Yunnan, and Chinese blue calico(resist printing) of Chinese private houses in the Hunan and Huseo regions, and these represent the three typical Chinese dyeing techniques today. Based on the results of empirical research on the utilizing cases, focusing on the traditional living handicrafts of Chinese minority races, traditional cultural articles, and artworks, the modern values such as practical, cultural, and artistic values of Chinese indigo dyed designs could be rediscovered.

It is essential to increase the switching speed of power devices to reduce the energy loss because high frequency is commonly used in power device operation these days. In this work electron irradiation has been conducted to reduce the lifetime of minority carriers and thereby to increase the switching speed of a$p^+- n^-$ junction diode. Effects of electron irradiation on the electrical properties of the diode are reported The switching speed is effectively increased. Also the junction leakages and the forward voltage drop which are anticipated to increase are found to be negligible in the $p^+- n^-$ junction diodes irradiated with the optimum energy and dose. The analysis results of DLTS and C-V profiling indicate that the defects induced by electron irradiation in the silicon substrate are donor-like ones which have the energy levels of 0.284 eV and 0.483 eV. Considering all the experimental results in this study, it might be concluded that electron irradiation is a very useful technique in improving the switching speed and thereby reducing the energy loss of $p^+- n^-$ junction diode power devices.

French poststructuralists Gilles Deleuze and Felix Guattari pointed out that the minority age already has come in the modern society through discussing minority topic. Futhermore, they supported 'Becoming' as new methodology that minorities escape from suppressed reality. 'Becoming' is the practical concept for how one identity could split into different lives and subjects, thus it could be explained as an exemplary that autonomous change and actively entering into different lives. The purpose of this study seeks the practical way for elder women can independently participate in media education which is based on concretely 'becoming woman'. For this, the article examines the main concept and thought of Deleuze and Guattari. The reason why this article premises this theory is for changing 'desire' of elder women's approach to 'becoming women' through new interpretation about minority and minorities which were defined by quantitative criteria. Consequently, this article would suggests the direction of senior media education for seniors for the positive and specific effect.
