O R I G I N A L P A P E R Influence of Socioeconomic Factors and Family Social Support on Smoking and Alcohol Use among Health School Students
Get PDFABSTRACT Background: Substance dependence is a global problem threatening individuals and communities alike by negatively influencing public health and social cohesion. Objective: The aim of this study was to investigate the influence of socioeconomic factors and family social support on substance use and/or dependence among health school students. Results: A significant difference was found between student substance users and nonusers in terms of age, grade level, educational level and vocational status of the student's mother and father, and substance use among family members (p<0.05). On the other hand, it was determined that there was no influence of departments of the students, receiving any training on substance use, perceived family social support, and educational level of the student's father on the substance use (p0.05). Conclusion: The findings of our study suggest that family social support is an important determinant of students' substance use and therefore families need to be aware of the consequences of such behaviors. Trainings on overcoming the stress and information about use and/or abuse of substances should be given to the first-grade students in Samsun Health School to prevent the onset of substance use, and the frequency of such training sessions should be increased especially at the fourth grade
Case Report A Patient with Four-Year Survival after Nonsmall Cell Lung Carcinoma with a Solitary Metachronous Small Bowel Metastasis
Get PDFSolitary small bowel metastasis secondary to lung cancer is very uncommon. In this report, we present a patient with NSCLC and a metachronous solitary metastasis of the jejunum. She is alive without evidence of disease and doing well four years after palliative surgery, radiotherapy, and chemotherapy. To the best of our knowledge, this is the first case report describing a prolonged survival in a patient with a symptomatic solitary small bowel metastasis treated with palliative surgery, chemo-and radiotherapy instead of complete surgical resection
LOW-DELAY WINDOW-BASED RATE CONTROL SCHEME FOR VIDEO QUALITY OPTIMIZATION IN VIDEO ENCODER
Get PDFABSTRACT The consistent video quality and encoding latency due to buffering are two important aspects in designing rate control scheme for the application of real-time video coding system. To well balance these two contrary objectives, we firstly analyze the constraint of buffer latency and the definition of a "consistent" video quality. Then a window-based rate control scheme is proposed with one window for controlling the rate and latency, while the other window for optimizing video quality. By applying low complexity frame level ratedistortion model in the testing sequences, our proposed method shows excellent performance in balancing the encoder buffer latency and optimized video quality. Besides, this one-pass rate control scheme is highly practical for the real-time video coding application. Rate control, buffer latency, video quality, window-based, video encode

On the concepts of biochemical ecology and hydrobiology: Ecological chemomediators
Get PDFAbstract-Earlier, the author published two books and some papers, in which he described conceptual foundations of new scientific disciplines -biochemical ecology and biochemical hydrobiology. These trends in research include studies of the role of chemical substances in interorganismal interactions, in communication and regulation of supraorganismal systems. Another part of biochemical ecology concerns studies of the destiny and transformation of external chemical substances when they interact with the organisms. Both natural and man-made compounds are interesting for biochemical ecology. The basic concepts of biochemical ecology include ecological chemomediators and ecological chemoregulators that have already been included in the body of modern conceptions and are used in modern ecological literature. Application of biochemical ecology to aquatic ecosystems creates the basis for development of biochemical hydrobiology
Developing an Elective Course on Satellite Communications in Undergraduate Electrical Engineering Curriculum
Get PDFAbstract Keywords: Antenna look angles, attitude control, eclipse, equinox. Introduction For more than seven decades, Parks College of Engineering, Aviation and Technology, one of the 12 schools and colleges at Saint Louis University, has had the tradition of excellence in aerospace education. Founded in 1927 as the first federally certified college of aviation in the country, Parks College prepares graduates for exciting and rewarding careers in aerospace industry and other related technological fields.The explosive growth of communications satellites and the perceived potential of the medium for novel applications have generated intense interests in both the government and private sectors. This warrants a large demand for a course in satellite communications suitable for students majoring in any of the electrical, avionics and aerospace engineering disciplines offered at Saint Louis University. This course is an attempt to include materials from those areas useful to understand the overall concepts of satellite communications. It provides a broad coverage of topics, in some cases very briefly, as practical as possible. It is based on the assumptions that students have completed the usual undergraduate courses in mathematics and physics to understand the concepts of orbital mechanics and electromagnetic fields. A minimum of basic electrical engineering that includes materials in electronics and circuit theory is required. Handouts are provided to some students lacking backgrounds in communications theory and electromagnetic radiation. Many related topics that are not covered in previous courses are presented following the -just-in‖ approach. From the techniques of orbital aspects and radio wave propagations to the design of communication links, the course treats the entire field of satellite communications A communications satellite is a very simple concept, but simple concepts sometimes change the entire fabrics of the society. Terrestrial communications face long distance constraints of requiring a physical path between terminals. A communications satellite, in essence, is a radio relay in the sky. Satellite communications engineering combines such diverse topics as orbital mechanics, satellite construction including various subsystems, launching and positioning of geostationary satellites, geometric considerations of satellite, space environments and its effects, radio wave propagation, and space link and satellite access. This paper focuses briefly on unconventional topics falling beyond the discipline boundaries. Mathematical rigors and complexities are purposely avoided in many cases to make it more enjoyable and at the same time comprehensible to students
