Update on Canine and Human Rabies in a Rabies Endemic Situation in the Republic of Guinea

Each year, rabies kills nearly 60,000 people worldwide. Asia and Africa are the most affected. It is a public health problem because of the number of stray dogs in these nations. In Guinea, rabies is endemic and cases are often under-reported. The objective of this study was to determine the prevalence of rabies among human and animal exposures in Guinea. This was a retrospective analytical study from 2019 to 2021 conducted in the country’s human and veterinary health divisions and, primarily focused on rabies épidémiologique surveillance. The selection was based on human contact with an animal causing behavioural disorders, as well as animals put under observation following aggression on humans. The data were analysed using Epi Info version 21 software. Qualitative variables were expressed as proportions with 95% CIs, quantitative variables as mean ± standard deviation. The chi2 test and the Fischer exact test were used to compare proportions. A total of 85 veterinary facilities were visited and 100 animals registered, of which 93% were reported cases of exposure to canine rabies. One thousand five hundred and thirty-one (1531) people exposed to rabies were recorded between 2019 and 2021. During the period, the prevalence of human rabies was 0.533% [0.042 - 0.064] at 95% CI and that of canine rabies was 0.55% [0.039 - 0.061] at 95% CI. The biting animal was the dog in 97.2% of cases. Subjects over 45 years of age (57.7%) were the most affected. The prevalence of canine rabies was 0.5% compared with 0.533% for human rabies between 2019 and 2021. This low prevalence does not reflect the true extent of the phenomenon in Guinea, as few people consult health structures in the event of dog bites. Regular surveillance of the human and dog population is necessary for better rabies control in Guinea.

Localized Excitations of （2＋1）-Dimensional Korteweg-de Vries System Derived from a Periodic Wave Solution

With the aid of an improved projective approach and a linear variable separation method, new types of variable separation solutions （including solitary wave solutions, periodic wave solutions, and rational function solutions） with arbitrary functions for （2＋1）-dimensional Korteweg-de Vries system are derived. Usually, in terms of solitary wave solutions and rational function solutions, one can find some important localized excitations. However, based on the derived periodic wave solution in this paper, we find that some novel and significant localized coherent excitations such as dromions, peakons, stochastic fractal patterns, regular fractal patterns, chaotic line soliton patterns as well as chaotic patterns exist in the KdV system as considering appropriate boundary conditions and/or initial qualifications.

The Evaluation of Social Sharing Nets Users’ Fundamental Principals According to Nickname Usage and Time Spent

This work;It was made to determine the positive and negative usage information, attitudes and behaviors of social networking networks for users. Today, it is well known how the wide social effects of social networking sites are widespread and effective. As far as it can be followed from written and visual media, it causes significant damages for attitudes and behaviors for individuals. Looking at the results of the study, it seems impossible to limit the time and necessity of these networks for people, but it is understood that people force their limits and capacity. It was determined that the general acceptance and rejection areas are mixed and the dominant distinctive effects were weakened. Unable to prevent social dissolution and deterioration was realized by these social networks of networks. However, we cannot only talk about negative effects because their positive effects should be mentioned. Data were obtained in this direction. For example, some segments encourage the users of these sites to have more freedom, to develop democracy and human rights awareness. However, the real problem is when and where to stand. This study;Social networking networks use information, attitudes and behaviors;It was carried out for the purpose of evaluating the use of nicknames and networks for the use of networks. The data of the study were obtained by the application of a questionnaire and the data obtained were analyzed with appropriate statistical analysis methods. In the first part of the study, field study/operational concept scanning is performed and theoretical information is included. In the second part, the purpose of the study, the problem status, the importance of the study, limitations, assumptions, problem question, research method, research universe and sample are specified and informed. In the third section, the data obtained using appropriate statistical methods are analyzed. In the last section, some important suggestions and comments are made in the light of the data obtained.

尝试教学法诞生的过程,充分证明尝试教学法的本土性和原创性。针对20世纪60年代"先讲后练"教学模式的弊病,萌发"先练后讲"的教学设想,经过10年的教育实验和探索,终于形成了尝试教学法。这种教学法抓住了学习的本质,突出学生为主体,具有鲜明的中国特色,教师易学易用,教学效果显著,深受师生欢迎。再经过10多年的教育实验和研究,提升为具有中国特色的尝试教学理论,它的理论核心是"学生能尝试,尝试能成功,成功能创新"。创造性地提出"尝试成功说",区别于美国桑代克提出的"尝试错误说",并提出达到尝试成功的七个要素。又经过10年的实验研究提出尝试教育理论。

Personal knowledge in educational autobiography:An investigation on“good teachers”

A good teacher has various characteristics.We can observe directly teachers'behaviors or read their professional papers.However,the effective way is to have teachers tell their personal life history or educational autobiography.The personal knowledge of a good teacher will be revealed through the personal life history.According to numerous educational autobiographies,a good teacher has two characteristics:being kind to students and having passion.

Combined energy detection and one-order cyclostationary feature detection techniques in cognitive radio systems

One of the main requirements of cognitive radio systems is the ability to detect the presence of the primary user with fast speed and precise accuracy. To achieve that, a possible two-stage spectrum sensing scheme is suggested in this paper. More specifically, a fast spectrum sensing algorithm based on the energy detection is introduced focusing on the coarse detection. A complementary fine spectrum sensing algorithm adopts one-order cyclostationary properties of primary user＇s signals in time domain. Since the one-order feature detection is performed in time domain, the real-time operation and low-computational complexity can be achieved. Also, it drastically reduces hardware burdens and power consumption as opposed to two-order feature detection. The sensing performance of the proposed method is studied and the analytical performance results are given. The results indicate that better performance can be achieved in proposed two-stage sensing detection compared to the conventional energy detector.
