Background: It is projected that low and middle-income countries will bear a major burden of tobacco related morbidity and mortality, yet, only limited information is available on the determinants of smoking initiation among youth in Africa. This study aimed to assess the determinants of smoking initiation and susceptibility to future smoking among a population of high school school students in Lagos, Nigeria. Materials and Methods: Baseline data from an intervention study designed to assess the effect of an anti-smoking awareness program on the knowledge, attitudes and practices of adolescents was analyzed. The survey was carried out in six randomly selected public and private secondary schools in local government areas in Lagos state, Nigeria. A total of 973 students completed self-administered questionnaires on smoking initiation, health related knowledge and attitudes towards smoking, susceptibility to future smoking and other factors associated with smoking. Results: Of the respondents, 9.7% had initiated smoking tobacco products with the predominant form being cigarettes (7.3%). Males (OR: 2.77, 95%CI: 1.65-4.66) and those with more pro-smoking attitudes (OR: 1.44, 95%CI: 1.34-1.54) were more likely to have initiated smoking. Those with parents and friends who are smokers were 3.47 (95%CI: 1.50-8.05) and 2.26 (95%CI: 1.27-4.01) times more likely to have initiated smoking. Non-smoking students, in privately owned schools (OR: 5.08), with friends who smoke (5.09), with lower knowledge (OR: 0.87) and more pro-smoking attitudes (OR 1.13) were more susceptible to future smoking. In addition, respondents who had been sent to purchase cigarettes by an older adult (OR: 3.68) were also more susceptible to future smoking. Conclusions: Being male and having parents who smoke are predictors of smoking initiation among these students. Consistent with findings in other countries, peers not only influence smoking initiation but also influence smoking susceptibility among youth in this African setting. Prevention programs designed to reduce tobacco use among in-school youth should take these factors into consideration. In line with the recommendations of article 16 of the WHO FCTC, efforts to enforce the ban on the sales of cigarettes to minors should be also emphasised.

Building Ukraine as an independent, sovereign state requires the education of a citizen-patriot, able to live and work in a democracy, ensure the unity of Ukraine, feel constant responsibility for themselves, their people, country, seek to make a real contribution to the reform process. Modern modernization of the education system requires the search for new information and communication technologies that can ensure the formation of a citizen with an active civic position, which involves not only students mastering the rights and responsibilities of citizens, convincing them of the feasibility of democratic transformation of society, patriotic qualities and feelings, but also the identification of motivated civic actions. The pandemic and hostilities have led to significant changes in the field of education around the world, they have caused educational problems in Ukraine. At the beginning of the quarantine in the spring of 2020, all educational institutions in the emergency mode switched to distance learning. Intensive use of information and communication technologies in the life of modern society has led to a rethinking of the content of education and training of future professionals: the main role is played not so much by the information itself as the ability to work with it, critically comprehend and produce new knowledge; the main thing is not the amount of information, but its quality; information is needed for further practical application and transformation into knowledge, and the ability to work with information becomes one of the important competencies of the modern specialist in the new transformation of society: from information to the knowledge society. In this context, one of the main forms of training is distance learning, which is able to respond to the challenges of society. The main methodological positions that are taken into account in the construction of the structure and dynamics of the formation of civic responsibility of the individual during the use of information and communication technologies are highlighted. The structure of civil responsibility as a holistic system of information and communication technologies is outlined, which includes three subsystems that characterize the natural, social and systemic qualities of citizenship, interconnected hierarchically and synergistically.The constituent elements of the structural part of the model of civic culture of the individual are analyzed.

This study examined changes of rumen fermentation, ruminal bacteria biodiversity and abundance caused by nitrate addition with Ion Torrent sequencing and real-time polymerase chain reaction. Three rumen-fistulated steers were fed diets supplemented with 0%, 1%, and 2% nitrate (dry matter %) in succession. Nitrate supplementation linearly increased total volatile fatty acids and acetate concentration obviously (p = 0.02; p = 0.02; p<0.01), butyrate and isovalerate concentration numerically (p = 0.07). The alpha (p>0.05) and beta biodiversityof ruminal bacteria were not affected by nitrate. Nitrate increased typical efficient cellulolytic bacteria species (Ruminococcus flavefaciens, Ruminococcus ablus, and Fibrobacter succinogenes) (p<0.01; p = 0.06; p = 0.02). Ruminobactr, Sphaerochaeta, CF231, and BF311 genus were increased by 1% nitrate. Campylobacter fetus, Selenomonas ruminantium, and Mannheimia succiniciproducens were core nitrate reducing bacteria in steers and their abundance increased linearly along with nitrate addition level (p<0.01; p = 0.02; p = 0.04). Potential nitrate reducers in the rumen, Campylobacter genus and Cyanobacteria phyla were significantly increased by nitrate (p<0.01; p = 0.01).To the best of our knowledge, this was the first detailed view of changes in ruminal microbiota by nitrate. This finding would provide useful information on nitrate utilization and nitrate reducer exploration in the rumen.

Wireless body area network (WBAN) is an emerging short-range wireless communication network with sensor nodes located on, in or around the human body for healthcare, entertainment and ubiquitous computing. In WBANs, energy is severely constrained which is the prime consideration in the medium access control (MAC) protocol design. In this paper, we propose a novel MAC protocol named Energy-efficient Relay MAC with dynamic Power Control (ERPC-MAC) to save energy consumption. Without relying on the additional devices, ERPC-MAC employs relaying nodes to provide relay service for nodes which consume energy fast. Accordingly the superframe adjustment is performed and then the network topology can be smoothly switched from single-hop to multi-hop. Moreover, for further energy saving and reliability improvement, the dynamic power control is introduced to adjust the power level whenever a node transmits its packets to the coordinator or the relaying node. To the best of the authors' knowledge, this is the first effort to integrate relay, topology adjustment and power control to improve the network performance in a WBAN. Comprehensive simulations are conducted to evaluate the performance. The results show that the ERPC-MAC is more superior to the existing standard and significantly prolongs the network lifetime.

Bovine whey protein expression patterns of colostrum are much different from that of milk. Moreover, bovine colostrum is an important source of protective, nutritional and developmental factors for the newborn. However, to our knowledge, no research has been performed to date using a comparative proteomic method on the changes in the bovine whey proteome during the transition from colostrum to milk. This study therefore separated whey protein of days 1, 3, 7 and 21 after calving using two dimension electrophoresis. Differentially expressed proteins at different collection times were identified using high-performance liquid chromatography in tandem with mass spectrometry (LC/MS) and validated by enzyme-linked immunosorbent assay (ELISA) in order to understand the developmental changes in the bovine whey proteome during the transition from colostrum to milk. The expression patterns of whey protein of days 1 and 3 post-partum were similar except that immunoglobulin G was down-regulated on day 3, and four proteins were found to be down-regulated on days 7 and 21 compared with day 1 after delivering, including immunoglobulin G, immunoglobulin M, albumin, and lactotransferrin, which are involved in immunity and molecule transport. The results of this study confirm the comparative proteomic method has the advantage over other methods such as ELISA and immunoassays in that it can simultaneously detect more differentially expressed proteins. In addition, the difference in composition of milk indicates a need for adjustment of the colostrum feeding regimen to ensure a protective immunological status for newborn calves.

The purposes of this study are to do surveys of the state of health and dental health behaviors of higher grade students in elementary school and their mothers, to investigate the relationship of students' dental health, and to apply those results to the systematic and efficient dental health care. The subjects were totally 618 people, including 309 elementary school students in 4th, 5th, or 6th grades and their mothers in Pusan. The questionnaires were used as instruments, which were made by the researcher and related with other preceeding studies. The content validity of the instruments was tested by two professors of nursing. Dental checking were conducted by an expert of dental sanitation, according to the standard of the World Health Organization. The period of collecting data was 20 months from October 20th to December 20th in 2000 and the collected data were analyzed by SAS program and classified as the real number, the percentage, the mean, the standard deviation, t-test, and F-test. In conclusion, there is no significant correlation between grades and treated or treatment-needed permanent teeth. There is the highest significant correlation between treated or treatment-needed permanent teeth and students' dental health behaviors. There is high significant correlation between mothers' dental health behaviors and students' dental health behaviors. Also, There is significant correlation between mothers' state of dental health and students' state of dental health. From the results of this study, the students' dental health behaviors are the most important variables in the students' state of dental health. But both boys(9.48) and girls(9.97) get the low marks on the total mark 15 about brushing, which can be self-controlled. Therefore, the developments of dental health guidance in education about dental health by mothers or the educational courses in schools, such as brushing educations by the experts, dental health education, brushing after lunch, or the various equipments in brushing, should be accomplished. Above all, behavior-centered education should be conducted instead of knowledge-centered education.

The purpose of this study was to analyze the smoking behavior and to provide the basic data required to develop a smoking cessation program. The study subjects were 407 industrial workers in Jecheon. The data were collected using a structured questionnaire. The data were analyzed by the SPSS 10.0 system using descriptive statistics, t-test, and Chi-square test. The study results were as follows 1. Current smokers were $64.0\%$, ex-smokers were $19.1\%$. and non-smokers were $16.9\%$. 2. The most common motives of smoking were anger. anxiety, depression. and stress in the workplace. 3. In smoking habits, about $65.1\%$ of the current smokers smoked 11-20 cigarettes/day, and $91.0\%$ had smoked for more than 5 years. The smoking areas of the workplace were outdoor $37.9\%,\;rest\;room\;34.2\%,\; lobby\;23.0\%,\;corridor\;21.4\%,\;and\;office\;8.6\%$. 4. Regarding smoking cessation, $78.2\%$ of current smokers had attempted. The frequency of smoking cessation attempts was 1-3 or less in $67.2\%$ of smokers. The duration of smoking cessation was 1-3 month or less in $61.6\%$ of the smokers. 5. The mean score for smoking knowledge was 17.62, smoking attitude 75.74. and perceived health state 12.27. 6. There were significant differences between smokers and non-smokers 10 smoking attitude (t=5.29, p=0.00), and perceived health state(t=6.47, p=0.00). 7. As a result of the homogeneity test, both types of smoking and perceived health state proved to have significant differences in the change of health state compared with 4 weeks ago'$(x^2=20.26,\;p=0.00)$ and the level of satisfaction of health state in activities of daily living'$(x^2=15.47,\; p=0.05)$. The important findings of this study showed that a smoking cessation program needs to be developed to enhance the negative smoking attitude. to promote the perceived health state through smoking cessation, to encourage the intention of smoking cessation, and to develop strategies of stress management.
