    The ensemble of low-density generator-matrix/low-density parity-check (LDGM-LDPC) codes has been proposed in literature. In this thesis, an irregular LDGM-LDPC code is studied as a sub-code of an LDPC code with some randomly emph{punctured} output-bits. It is shown that the LDGM-LDPC codes achieve rates arbitrarily close to the channel-capacity of the binary-input symmetric-output memoryless (BISOM) channel with a finite lower-bound on the emph{complexity}. The measure of complexity is the average-degree (per information-bit) of the check-nodes for the factor-graph of the code. A lower-bound on the average degree of the check-nodes of the irregular LDGM-LDPC codes is obtained. The bound does not depend on the decoder used at the receiver. The stability condition for decoding the irregular LDGM-LDPC codes over the binary-erasure channel (BEC) under iterative-decoding with message-passing is described. The LDGM-LDPC codes are capacity achieving with bounded complexity and possess natural binning/nesting structure. These codes are applied to secrecy coding. The problem of secrecy coding for the type-II binary symmetric memoryless wiretap channel is studied. In this model, the main channel is binary-input and noiseless and the eavesdropper channel is binary-symmetric memoryless. A coding strategy based on emph{secure nested codes} is proposed. A capacity achieving length-nn code for the eavesdropper channel bins the space 0,1n{0,1}^n into co-sets which are used for secret messaging. The resulting co-set scheme achieves secrecy capacity of the type-II binary symmetric memoryless channel. As an example, the ensemble of capacity-achieving regular low-density generator-matrix/low-density parity-check (LDGM-LDPC) codes is studied as a basis for binning. The previous result is generalized to the case of a noisy main-channel. The problem of secrecy-coding for a specific type-I wiretap channel is studied. In the type-I wiretap channel under consideration, the main channel is a binary-input symmetric-output memoryless (BISOM) channel and the eavesdropper channel is a binary-symmetric channel (BSC). A secure-nested-code that achieves perfect-secrecy for the above type-I channel is proposed. The secure-nested-code is based on a nested regular LDGM-LDPC code construction.M.S.Includes bibliographical referencesby Manik RainaIncludes abstrac

    Indonesia merupakan negara yang memiliki banyak sekali sentra kerajinan tangan yang terletak pada area pedesaan. Salah satu desa sentra kerajinan di Indonesia yang masih bertahan hingga saat ini adalah sentra kerajinan manik-manik kaca di Gudo, Jombang, Jawa Timur. Pada era 90-an, sentra kerajinan ini sangat sukses namun beberapa dekade ini mengalami penurunan pemasukan dikarenakan kurangnya inovasi serta wawasan mengenai pengembangan produknya. Untuk itu, penulis membantu mengembangkan produk-produk hasil manik-manik kaca pengrajin yang sebelumnya output produk hanya perhiasan sederhana menjadi produk yang dapat digunakan pada aktivitas sehari-hari seperti produk tas dengan menggunakan acuan konsep trend-forecasting 2020/2021 “ Essentiality”. Penulis melakukan eksplorasi material untuk mencari alternatif teknik baru yang dapat digunakan pengrajin. Lalu penulis menerapkannya pada produk baru yaitu produk tas. Selanjutnya, penulis melakukan pelatihan bersama para pengrajin guna memperkenalkan teknik eksplorasi baru dan saling bertukar pendapat bersama pengrajin, dan bersama-sama mengembangkan produk-produk menggunakan teknik baru ke arah yang lebih luas lagi. Hasil produk dari pelatihan cukup beragam antara lain produk apparel, perhiasan, home decor, bathroom set, hal ini membuktikan bahwa sebenarnya pengrajin juga dapat berinovasi secara luas. ===================================================================================================== Indonesia is a country that has many handicraft centers located in rural areas. One of the craft center villages in Indonesia that still survives today is the glass bead craft center in Gudo, Jombang, East Java. In the 90s, this craft center was very successful but in recent decades its income has decreased due to lack of innovation and increased product development. For this reason, the author helps develop products from glass bead craftsmen who were previously only jewelry jewelry that can be used in daily activities such as bags by using the concept of forecasting the 2020/2021 trend "Essentiality". The author explores the material to find alternative new techniques that can be used by craftsmen. Then the author applies it to a new product, namely bag products. Furthermore, the authors held training with the craftsmen to introduce new exploration techniques and exchange opinions with the craftsmen, as well as jointly develop products using new techniques in a broader direction. The results of the training were quite diverse, including clothing products, jewelry, home decorations, bathroom equipment, this proves that the actual maker can also be seen widely

    TITLE: Gender differences in substance use and depression among caregivers AUTHOR INFO Memunat Ogunmefun Manik Ahuja Author Affiliations: College of Public Health, East Tennessee State University, Johnson City, TN 37614, United States Background: Around 20% of adults in the United States provide care for a loved one, with approximately 61% of these caregivers identifying as women. Typically, a caregiver is defined as someone who provides help and support to a family member or friend who is facing illness or disability as a result of a medical condition. Caregiving may be rewarding, but it can also cause significant psychological strain, leading to adverse consequences, such as turning to substance use to cope with stress. Increased levels of stress in caregivers can make them more susceptible to various health problems, such as depression and anxiety disorders, sleep disturbances, compromised physical health, cardiovascular disease, and substance use disorders. The aim of this study is to examine the gender differences in substance use and depression among caregivers using a nationally representative sample. Methods: We used cross-sectional data from the 2021 Behavioral Risk Factor Surveillance System a nationally representative U.S. telephone-based survey of adults aged 18 years and extracted data for non-metropolitan/rural counties. Logistic regression analyses were conducted separately to test the association between self-identified caregiver status and three outcomes, including depression and current alcohol use. We controlled for past month’s income, race, educational status, and age. Caregiver status was identified based on providing care or assistance to a friend or family member over the last 30 days. Results: Overall, 21.7% (n=13,653) of our participants self-identified as a caregiver, while 19.5% reported depression, past month alcohol use (48.2%), past month smoking (13.5%), and past month marijuana use (4.2%). Significant interactions were found between caregiver status and gender (p=.0001). We then stratified by gender. Among males, self-identified caregiver status was associated with higher odds of depression (OR=1.48, 95% CI, 1.41,1.55). Among females, caregiver status was associated with higher odds of depression (OR=1.48, 95% CI, 1.29, 1.39). Caregiver status did not predict alcohol use. Conclusion: Caregiving has been known to cause psychological strain which may be associated with alcohol use and depression. According to this study, being a caregiver may contribute to depression regardless of gender, but it does not necessarily affect alcohol consumption. The gender differences observed in this study highlight the need for interventions and support programs that are tailored to meet the unique needs and challenges faced by male and female caregivers. It is important for healthcare professionals to consider caregiver status and gender when assessing mental health risk factors

    TITLE: Racial disparities associated with colon cancer screening in a nationally representative sample; A cross-sectional study AUTHOR INFO Yorandos Tafesse MD1 Manik Ahuja PhD, MA1 Author Affiliations: 1College of Public Health, East Tennessee State University, Johnson City, TN 37614, United States Colon cancer impacts nearly 2 million individuals in the U.S. each year. Early detection of colon cancer using colonoscopy can reduce the risk of mortality. The United States Preventive Services Task Force (USPSTF) recommends routine screening for colon cancer for all adults 50 to 75 years of age. Colon cancer screening behavior is different across a variety of predictor variables. Previous studies have identified older age, male gender, higher education, higher income, marriage, and the presence of chronic diseases to be associated with increased odds of colon cancer screening. However, less is known about the role of racial differences in screening. This study aims to determine if colon cancer screening rates are different between Whites and racial minorities in the United States controlling for potential confounders. This research can help bridge the existing gap on this topic and aid in identifying high-risk racial groups that could be targeted by future intervention strategies. We used cross-sectional data from the 2019 Behavioral Risk Factor Surveillance System, a nationally representative U.S. telephone-based survey of adults aged 18 years or older. We extracted data for adults age 50 or older (n=10,972). Logistic regression analyses were conducted to test the association between race and colon cancer screening. We also included chronic disease status, alcohol use, smoking, gender, and age in our model. Chronic disease status was coded as self-report 2 or more, 1 and 0 chronic diseases (referent), which included the summation of heart disease, hypertension, COPD, and diabetes. Overall, colon cancer screening is as follows among Whites (77.2%), Blacks (72.4%), Asian (60.1%), American Indian/Alaska Native (69.7%), and Hispanic (68.6%). Logistic regression results revealed that having 2 or more chronic diseases (OR=1.73; 95% CI 1.53,1.96), 1 chronic disease (OR=1.45; 95% CI 1.31,1.65), and female gender (OR=1.14; 95% CI 1.04,1.23) were associated with higher odds of screening. Race/ethnic minority status (OR=0.72; 95% CI 0.65, 0.81), low income (OR=0.64; 95% CI 0.57,0.70), and less than high school education (OR=0.71; 95% CI 0.59,0.84) were associated with lower odds of screening. Our research showed that racial minorities have lower odds of colon cancer screening after adjusting for gender, age, chronic diseases, income, and education status. Preventive practices should focus on increasing awareness on and availability of colon cancer screening means to racial minorities in the United States. Further research on the association between race and other screening modalities will help maximize the impacts of targeted interventions

    TITLE: Race, gender, and mental health outcomes in Tennessee AUTHOR INFO Eugene Annor Manik Ahuja PhD, MA1 Author Affiliations: 1College of Public Health, East Tennessee State University, Johnson City, TN 37614, United States Background: Tennessee has been disproportionally burdened with high levels of mental health disorders. Over the last decade, Tennessee has consistently ranked in the bottom 10 U.S. states in prevalence of mental health disorders. While it is known that Tennessee ranks lower in mental health status, less is known of how these differences vary across race. Methods: We used cross-sectional data from the 2019 Behavioral Risk Factor Surveillance System, a nationally representative U.S. telephone-based survey of adults aged 18 years or older for the State of Tennessee (n=6,242). Chi-square tests were conducted to assess differences across race. Logistic regression analyses were conducted to test the association between gender and past month mentally unhealthy days, stratified by race. We coded mentally unhealthy days binary, at 15 or more mentally unhealthy days in the past month, and less than 15 days. We controlled for income, educational attainment, health insurance, and age. Results: Overall, 22.9% of American Indian/Alaska Natives, followed by White (14.8%), Black (13.6%) and Hispanic (12.0%) reported 15 or more mentally unhealthy days in the past month. Among Blacks, there were no significant differences between males (13.2%) and females (13.9%) for 15 or more past month mentally unhealthy days (p=.76), as well as among Hispanics (p=.17) Among Whites, females (16.6) reported a significantly higher (p Conclusions: Our findings reveal that among Blacks and Hispanics in Tennessee, there were no significant gender differences in mental health outcomes. White among Whites and American Indian/Alaska Natives, females reported a significantly higher rate of past month mentally unhealthy days. The current study reports that the gap among males and females in report of poorer mental health has narrowed, particularly among Blacks and Hispanics in Tennessee. Further efforts towards providing equitable access to mental health services across race and gender in Tennessee, is essential
