Health Risk of Obesity in Native American Adolescents

10.11591/ijphs.v4i2.4718
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.

10.11591/ijece.v5i3.pp539-547
Tsung-Hui Chuang , Guan-Hong Chen , Meng-Hsun Tsai , Chun-Lung Lin
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.

Mostafa Abdul Fellani , Aboubaker M. Gabaj
The industrial application of Coupled Tank System (CTS) is widely used especially in chemical process industries. The control of liquid level in tanks and flow between tanks is a problem in the process technologies. The process technologies require liquids to be pumped, stored in tanks, and then pumped to another tank systematically. This paper presents development of Proportional-Integral-Derivative (PID) controller for controlling the desired liquid level of the CTS. Various conventional techniques of PID tuning method will be tested in order to obtain the PID controller parameters. Simulation is conducted within MATLAB environment to verify the performances of the system in terms of Rise Time (Ts), Settling Time (Ts), Steady State Error (SSE) and Overshoot (OS). The trial and error method of tunning will be implemented and all the performance results will be analyzed using MATLAB. It has been demonstrated that performances of CTS can be improved with appropriate technique of PID tuning methods.

10.11591/ijece.v5i3.pp586-598
Yunjin Lee , Mingyu Lim , Yangchan Moon
In this paper, we present our communication middleware (CM), which is designed to reduce the effort of developing common communication functionalities for social networking services (SNSs) in the client-server model. SNS developers can apply the application-level communication services of CM both to an SNS server and to client applications simply by calling application programming interfaces (APIs) and configuring various options related to communication services. CM was developed to enable SNS developers to easily build fundamental services such as transmission of a user-defined event, user membership and authentication management, friend management, content upload and download with different numbers of attachments, chat management, and direct file transfer. All of the communication services also provide options that a developer can customize according to his or her SNS requirements.

Thoracic time-sequential MRI can be used to assess diaphragm motion pattern without exposing radiation to subject. Clinicians may employ the motion to evaluate the severeness of chronic obstructive pulmonary disease (COPD). This study proposed a novel method of diaphragm motion extraction method on time-sequential thoracic MRI in sagittal plane. Otsu’s threshold and active contour algorithm are used to obtain diaphragm boundary. An automatic diaphragm motion tracking and extraction of respiratory pattern are also performed based on the diaphragm boundary. A total of 1200 frames time-sequential MRI in sagittal plane was obtained for total of 15 subjects (8 healthy volunteers and 7 COPD patients). The proposed method successfully extracts diaphragm motion and respiratory patterns for both healthy volunteers and COPD patients. DOI: http://dx.doi.org/10.11591/telkomnika.v14i2.7375

Power Optimization of Spark Ignition Engine by Fuzzy Logic Ignition Controller Based on Knock Detection

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/1475
Agus Sujono , Raden Soekrisno , Eka Firmansyah , Oyas Wahyunggoro
Spark ignition engines have many advantages, but to increase the power and efficiency, they have a problem to set the right ignition timing, at which the maximum power can be delivered. In reality, the optimum ignition time is immediately prior to, or close to, the moment of detonation (knock). On the other hand, the value of this optimum ignition timing is dependent primarily on the rotation of the crank shaft and the level of throttle openings. To provide the right  timing proficiency level, it is very difficult to overcome the mechanical control system as found in conventional engines. So, in this study, a new electro-mechanical method based on Fuzzy Logic Ignition Controller (FLIC) which follows the pattern of the timing in the detonation chart was created. The results of the FLIC study, in fact, are able to provide correction for each spark plug ignition, according to the data on the chart of the optimal ignition timings for all combinations of engine rotations and throttle openings. From the final data recorded, it can be said that the FLIC influence on the power output which increases of up to 15% above normal. DOI: http://dx.doi.org/10.11591/telkomnika.v14i2.7597
