Benjamin David Knisley , Grace Crosby , Margaret Barth , Linn Carothers
Recent reports demonstrate the need to improve methods for identifying obesity among adolescent minority populations, especially among Native American adolescents. Our study examined several anthropometric measures to see which one was the best indicator of obesity for Native American adolescents. We compared our data with that provided by the Centers for Disease Control and Prevention (CDC), and the national Health and Nutrition Examination Surveys (NHANESIII). We examined which measures differed significantly from the NHANESIII, and which were most effective for measuring obesity in Native American adolescents. Our study population represented a cross-sectional, epidemiological population (n=183) of Native American students (ages 14-18) from diverse tribal backgrounds at an urban residential high school. We obtained baseline anthropometric measurements of height, weight, waist, triceps skin-fold, and calf skin-fold measures from the Native American students and compared this information with reference data to assess weight classification by body mass indices (BMI) for our population. Under the conditions of our study, we found the calf skin-fold measure to be the best indicator of normal weight in male Native American adolescents, and the triceps skin-fold measure to be the best indicator of obesity in male Native American adolescents. The assessment of health risk by anthropometric measures we obtained appears appropriate for predicting obesity and developing effective interventions for Native American adolescents in general. Correlations between anthropometric measures and obesity in our study population may prove of significant interest for monitoring obesity prevention initiatives for Native American adolescents.

Juneman Abraham , Miranti Ayu Puteri
The quality life of breast cancer survivors has been the psychology’s focus of attention. However, studies discussing their sexuality highlighted from the social psychology perspective are still not very much, especially in Indonesia. This study aimed to predict sexual self-schema of breast cancer survivors based on their perceptions of the breast talk and physical self-concept. This study used a predictive-correlational design and employed psychological scales measuring instruments, multiple linear regression data analysis technique as well as purposive sampling method. This study was conducted on 130 women breast cancer survivors (Mage = 39.45 years old; SDage = 3.542 years; all been married) in Special Capital Region of Jakarta - the capital city of Indonesia, and its surrounding areas (Bogor, Tangerang, and Bekasi). The study results showed that the perception of functional breast talk and physical self-concept are able to predict sexual self-schema in positive directions. Other perceptions of breast talk (medicalized, gendered, and sexualized breast talk) are not able to predict it. This study has important implications in order to improve the life quality of the survivors, namely by managing fair discourses about breast in the public and keeping the proper physical self-concept since the early stage of life.

The Impacts of Biotechnology on Biodiversity in Global Health: A Case Study on Avian Influenza in Bangladesh

10.11591/ijphs.v4i2.4719
Muhiuddin Haider , Milind Patel , Priyanka Bhattacharjee , Maariya Bassa
Biodiversity is the variability of between genetics, species, or ecosystems of living organisms within a specific region. Biodiversity is essential for sustaining healthy living networks and systems because it allows for a variety of food sources, medicine, and biological control, while also playing a significant role in atmospheric regulation, nutrient cycling, and pollination. Loss of biodiversity and ecosystem change increases the risk of the emergence or spreading of infectious diseases and global pandemics such as the Avian Influenza (AI H5N1). Biotechnology is one solution for reducing, and ultimately eliminating, the transmission of avian influenza. Traditional methods of treating infected animals, such as common vaccines, are temporary solutions that have no effect on the biodiversity of an ecosystem. Methods in animal biotechnology such as artificial insemination, embryo transfer, and in vitro fertilization have led to developments of cheaper, safer, and more effective vaccines. Livestock that have been treated for H5N1, as well as those that are healthy and have never been infected have proven to increase the diversity, leading to the elimination of specific issues. Similar effects are attainable if these animal biotechnology methods were to be used on poultry infected with the avian influenza virus.

Abdelghani Rouini , Djillali Mahi
High voltage device dimensioning requires the prediction of the withstand voltage for test conditions  like impulses, surges and AC voltage. There is a large need of designer to have reliable design criteria and well-defined simulation procedure for device development. This parametric study is based on the methodology of experimental  designs.  This method allowed us  to  propose  a mathematical polynomial model. The objective of this paper is to study the discharge phenomena for a point –plane air  interval with insulating barrier between them. Firstly on experimental study of a laboratory setup that we designed to carry out the influence of parameters (geometrical) involved in the process of breakdown. The distance between electrodes and different parameters of the barrier such as its position between electrodes dimension and its holes is studied . The barrier acts as a geometrical obstacle against the direct propagation of discharge. Secondly, using results obtained by the experimental setup , we have experiments design  methodology of technique to predict the breakdown threshold voltage.

In the LTE-Advanced network, some femtocells are deployed within a macroecell for improving throughput of indoor user equipments (UEs), which are referred to as femtocell UEs (FUEs). Cross-tier interference is an important issue in this deployment, which may significantly impact signal quality between Macrocell Base Stations (MBSs) and Macrocell User Equipments (MUEs), especially for MUEs near the femtocell. To relieve this problem, the Third Generation Partnership Project Long Term Evolution-Advanced (3GPP LTE-Advanced) de fined the cognitive radio enhanced femtocell to coordinate interference for LTE-Advanced Network. Cognitive radio femtocells have the ability to sense radio environment to obtain radio parameters. In this paper, we investigated the performance of existing schemes based on fractional frequency reuse. Therefore, we proposed a scheme with cognitive radio technology to improve the performance of fractional fre-quency reuse scheme. Simulation results showed that our scheme can effectively enhance average downlink throughput of FUEs as well as the total downlink throughput in LTE-Advanced Networks.

Shahana Bano , K.Rajasekara Rao
In this paper we proposed a method which avoids the choice of natural language processing tools such as pos taggers and parsers reduce the processing overhead. Moreover, we suggest a structure to immediately create a large-scale corpus annotated along with disease names, which can be applied to train our probabilistic model. In this proposed work context rank based hierarchical clustering method is applied on different datasets namely colon, Leukemia, MLL medical diseases. Optimal rule filtering algorithm is applied on these datasets to remove unwanted special characters for gene/protein identification. Finally, experimental results show that proposed method outperformed existing methods in terms of time and clusters space.
