Deficiency in access to housing is a major manifestation of poverty. In the city of Bangalore, the poor and the marginalized constitute nearly 30 percent of the 8.47 million population (2011 Census) and are living in the nearly 640 slums in addition to squatter settlements and pavements. The city sprawls over an area of 741 sq. kms (2007 estimates) and the poor have very little access to personal living space. According to the Integrated Housing and Slum Development Program guidelines, each household with four average members should have 25 sq. meters of living space. In the case of poor of Bangalore, the attainment of even this minimum is a far cry. In recognition of this acuteness with regard to the problem of housing, the government has introduced schemes like the Jawaharlal Nehru National Urban Renewal Mission and the Rajiv Awas Yojana. And these schemes have witnessed only a limited success. Whenever the problem of housing for the urban poor is considered, the state and location of slums get into focus. The people living in slums are a crucial and inevitable support to the city economy. Relocation of slum people is fraught with loss of productivity and strain on the transport system and on the incomes of the poor. Their needs like housing, schooling, health centers, creches, hospices etc. have to be provided for. Financial support to the poor with regard to their housing needs will have to be imaginatively provided by banks and related institutions.

Marginalized random effects models (MREM) are commonly used to analyze longitudinal categorical data when the population-averaged effects is of interest. In these models, random effects are used to explain both subject and time variations. The estimation of the random effects covariance matrix is not simple in MREM because of the high dimension and the positive definiteness. A relatively simple structure for the correlation is assumed such as a homogeneous AR(1) structure; however, it is too strong of an assumption. In consequence, the estimates of the fixed effects can be biased. To avoid this problem, we introduce one approach to explain a heterogenous random effects covariance matrix using a modified Cholesky decomposition. The approach results in parameters that can be easily modeled without concern that the resulting estimator will not be positive definite. The interpretation of the parameters is sensible. We analyze metabolic syndrome data from a Korean Genomic Epidemiology Study using this method.

Background: Leukoplakia is an asymptomatic and potentially malignant change in the oral mucosa and high frequencies have been reported among smokers. The present study concerned the prevalence of tobacco use and leukoplakia and also associations between the two. Study design: This cross sectional survey was conducted amongst the Gond tribal population of Kundam Block, Jabalpur district, Madhya Pradesh state, Central India during 2007 to 2009. Screening for leukoplakia was conducted by a medical officer with two mouth mirrors. It is only based on visual inspection and oral pathology was not performed. A semi-structured questionnaire was used to collect information on socio-demographic and smoking habits. Prevalence of leukoplakia among users and non-users of tobacco was calculated in terms of percentages. Results: Of 1,552 individuals aged more than 12 years of age who were screened, 144 (9.3%) were found to have oral leukoplakia. The prevalence of leukoplakia was significantly elevated among tobacco users as compared to non-users (11% vs 2.5%; p<0.001). The percentage of leukoplakia was almost similar in both tobacco smokers and chewers (9% vs 11%; p=0.304). However, the percentage of leukoplakia was especially high among those chewers who also smoked tobacco (21.9%). Conclusions: The findings of the present study showed a positive effect of tobacco use and prevalence of leukoplakia. Also the prevalence was very high among Gond tribe, a marginalized population living in central India. There is a need for effective screening and treatment of leukoplakia in this area.

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 purpose of this study was to find the existential meanings of the culturally marginalized community organization. Based on the findings, the study examined the issues related to operating the organization and found the ways of helping such organization through service learning programs. For the study, the researcher chose the Korean school of Knoxville in the USA as a service community organization. This study used a qualitative method using narrative construction in the nature of the text shapes with first-person point of views. The research findings were discussed based on the observations and participation in the organization. The study found that the Korean school plays a role as a cultural liaison connecting the Korean culture to other cultures while enabling students to critically accept their native systems, values, and customs through understanding of their native language. However, problems were found in operating the school due to the lack of skills and knowledge of the school administration. Suggestions were made and implemented to the school in order to improve the performance of the school.

The global goat population continues to grow and is now over one billion. The number of goats raised primarily for milk production is also growing, due to expanding demand. Most of the world dairy goat production and consumption is in Asia, but a global view of the dairy goat sector reveals important lessons about building successful modern dairy goat industries. The most organized market for goat milk is found in Europe, especially in France. The European goat sector is specialized for milk production, mostly for industrial cheesemaking, while also supporting traditional on-farm manufacturing. Government involvement is significant in sanitary regulation, research, extension, support for local producer organizations, and markets, and ensures safety and quality. Nonetheless, producers are still vulnerable to market fluctuations. New dairy goat industries are developing in countries without a long goat milk tradition, such as China, the United States, and New Zealand, due to rising consumer demand, strong prices, and climate change. The mix of policies, management and markets varies widely, but regardless of the country, the dairy goat sector thrives when producers have access to markets, and the tools and skills to sustainably manage their livestock and natural resources. These are most readily achieved through strong and inclusive producer organizations, access to technical services, and policies that enable the poor and marginalized groups to benefit from increasing demand.

As population concentration, high-rise, and high-density progresses amid rapid industrialization and urbanization in Korea, green areas in the city have decreased significantly and the natural environment has deteriorated day by day due to various development projects. In order to cope with these social changes, many studies related to park and green areas have been conducted, but in the case of Gwangju-si, only studies on green areas such as vegetation structures, street facilities, and recreation forests have been conducted on park green areas. The situation is not losing. Therefore, in this study, a survey was conducted on Gwangju citizens to understand the usage behavior and satisfaction of park green areas, and to provide basic data for future park development and reorganization. As a result, first, to induce a variety of static and dynamic activities in order to increase the park satisfaction of Gwangju citizens, it is possible to create a park that has not been formed as soon as possible, and by planning programs with various themes. Second, it is necessary to expand green space services in marginalized areas by creating water streams, flower pots, and rooftop greening around the lives of Gwangju citizens, and create park green spaces with themes using cultural and historical resources for each administrative district. Third, in order to solve the dry landscape in some urban areas, it is necessary to establish a three-dimensional landscape plan by creating a variety of green areas such as potted plants, green areas, and street trees, and by giving functions of park green areas such as expanding leisure and convenience facilities.

이 연구는 인도네시아 이슬람 극단주의 역사와 최근의 인도네시아의 국제 이슬람 극단주의의 확산 실태를 조사한다. 이 연구의 수행을 위해서는 인도네시아 이슬람 극단주의 관련 문헌조사와 관련자들의 질적 인터뷰를 병행한다. 문헌조사를 위해서는 미디어 보도, 관련 연구 보고서와 논문 등을 수집하고 활용한다. 질적 인터뷰를 위해서는 국내체류 인도네시아 학생들과 체류자들, 인도네시아인과 결혼한 한국인 배우자들, 인도네시아 현지에서 활동하는 한국인 선교사들 등을 포함한다. 이들에 대한 질적 인터뷰는 30분에서 2시간에 걸쳐 진행되었다. 연구대상의 모집단을 사실상 특정화 할 수 없으며 연구주제의 성격상 인터뷰 대상에 접근이 용이하지 않았기 때문에 편의 샘플과 눈덩이 샘플 추출 방식을 활용하였다. 연구결과에 따르면, 인도네시아의 이슬람 극단주의는 뿌리가 깊고 일반적으로 아프가니스탄, 파키스탄, 이집트, 사우디아라비아 등과 같이 이슬람 극단주의가 공고히 뿌리를 내리고 있는 다른 무슬림 국가들과 유사한 역사적 경험을 공유한다. 즉, 서방 제국주의에 대한 반작용으로 이슬람 원리주의가 시작되었으며, 독립이후 근대국가 발전과정에서 소외되었고 소련-아프간 전쟁을 거치며 극단화 폭력화 하는 과정을 거쳤다. 또한 9.11테러 이후 국제적 이슬람 극단주의 네트워크와 연결되어 글로벌 지하드에 편입되는 발전경로를 보여준다. 이러한 역사적 발전 궤적은 인도네시아의 이슬람 극단주의가 상당히 조직적이고 공고하다는 것을 알려준다. 한편, 최근 들어 IS와 알카에다 등의 국제 이슬람 극단주의 세력의 동아시아 확장전략에 따라 인도네시아로의 침투와 확장이 관찰된다. 이는 특히 인도네시아의 소외되고 낙후한 시골지역에서 보다 뚜렷이 관찰된다. 이러한 인도네시아에서의 국제 이슬람 극단주의 세력의 확산은 지리적 근접성, 국내 상당규모의 이주자 공동체의 존재 등의 사실을 고려할 때 직접적으로 우리 국가에 위협을 미치게 될 것이다. 이러한 맥락에서 인도네시아 내에서의 이슬람 극단주의 확산 동향에 대한 주의와 관심은 시기적으로 매우 필요하다고 볼 수 있다.
