However, many obstacles such as poor financial support, lack of time and poor nutritional knowledge can influence achievement of optimal nutrition which is proportional to the level of the athlete's physical activity. The purpose of this study was to determine the level of nutritional knowledge and dietary behavior of athletes in Khorramabad in 2013. Professional athletes of Khorramabad, Iran, with more than one year of regular exercise and at least one course participating in national championships competitions were studied in this cross-sectional, descriptive-analytic study. The samples included 247 athletes aged 17-29 years. Their nutritional knowledge and behavior were measured by the nutritional knowledge and behavior inventory. Results: The results showed a significant difference in nutritional knowledge of athletes by gender and educational level; female athletes have higher nutritional knowledge than male athletes. A gender-dependent difference was found in nutritional behavior; despite their higher nutritional knowledge, female athletes have weaker nutritional behavior than male athletes. However, no significant correlation was found between BMI and nutritional knowledge and behavior of the athletes. Moreover, findings showed that nutritional knowledge and behavior could be significantly different in various sports.展开更多

Methods: 300 students were selected for routine clinical teaching in the first half of 2021 and clinical nutrition teaching in the second half of 2021. After that, questionnaires were used to understand the medical students knowledge, attitude towards nutrition and dietary behavior, and to analyze the effect before and after clinical nutrition teaching. Results: after clinical nutrition teaching, the students awareness rate of nutrition knowledge was significantly higher than before nutrition education, the difference was statistically significant (P < 0.05). After receiving the teaching of clinical nutrition, the students pay close attention to their own nutritional status, which is manifested by the learning attitude of eager to learn nutritional knowledge. Among them, 279 (93.0%) students express that nutritional knowledge is very important, 297 (99.0%) students express that they are willing to take the initiative to learn more nutritional knowledge, and 279 (93.0%) students express that regular eating of snacks will affect their health status. 294 cases (98.0%) of students said it was very important to have breakfast in the morning. However, there were still 180 cases (60.0%) of students who preferred to sleep late rather than eat breakfast early. After the teaching of clinical nutrition, the rates of breakfast, body weight, regular and quantitative meals, fresh vegetables, fruits, bean products, dairy products, nuts, seafood, meat and eggs, carbonated drinks, western fast food, sweets, fried foods, preserved fruits, puffed foods, diet and supper were significantly higher than before (p < 0.05). Conclusion: after receiving clinical nutrition teaching, medical students nutrition knowledge, attitude and eating behavior have been significantly improved, and there is a high probability to control their own diet by using good nutrition knowledge and positive eating attitude, so as to improve their health. It has obvious application significance and is worthy of promotion.展开更多

Methods A cross-sectional survey was anonymously self-administrated by way of computer to all the 1st graders' among three vocational high schools in a district of Shanghai. Four cognition indicators, including perceived benefits, perceived barriers, perceived risks and self eJficacy were applied according to Health Belief Model. Results The percentage of respondents who reported ever sexual practices and contraceptives use at first sex was 7.01% and 56.64% respectively. Condom (58. 70%) and oral contraceptive pills (27.78%) were used by the majority. Main reasons for non-use were "shy to buy it" (26.53%) and "partner don't want to use any" (18.37%). Proportion of respondents who ever had sex regarded withdrawal and rhythm as effective were 68.35% and 68.42% respectively. Proportion of respondents having sex knew "If a person was infected with STDs, he/she might not have noticeable symptoms" were 22.86%. Proportion of respondents who reported non-use of contraceptives at first sex considered that "infrequent intercourse could not cause a girl pregnant even she had experienced her menstruation" were 40.63%. Proportion of respondents who had ever used condom got full score of knowledge on "how to correctly use condom" were 23,26%. Perceived risks were poorest among four cognition indicators. High level of contraceptive knowledge was connected with high rate of contraceptives use at first sex, whereas high level contraceptive cognition was connected with high rate of contraceptive use both at first and recent sex. Conclusions It is important to provide youth-friendly services as well as message on contraceptives among vocational school students.展开更多

Students (N = 185) from three high schools in the district were asked through their class teachers to voluntarily complete the questionnaire. Results indicated that about 41% (n = 77) of the students lacked knowledge regarding potential sources of radiation exposure and 70% (n = 133) lacked knowledge regarding radon gas being the number one risk factor for lung cancer among non-smokers. Additionally, the ANOVA test indicated significant knowledge differences among school location. Students in school #1, located in the most affluent area, had significantly higher knowledge scores (M = 4.39) than school #2 located in a moderately affluent area (M = 3.50). Furthermore, we found significant differences in ethnicity on the environmental health attitude of the high school students. Black students reported lower positive environmental health attitude (M = 29.86) than White students (M = 32.63), Hispanic students (M = 32.33) and Asian students (M = 33.84). These findings demonstrated knowledge deficiency in some key areas in environmental health particularly the environmental diseases and conditions caused by manmade hazards such as pesticides, chemicals, radiation, air, water, and soil pollution. Targeted educational interventions to increase awareness and understanding of health effects, exposure to environmental hazards and carcinogens as well as risks associated to direct exposure as in this study, radon and radiation, should be provided to high school students. Practical education through tours where students can observe directly and participating in laboratory experiments could empower the students to translate this knowledge into positive environmental health behaviors and practices now and in the future.展开更多

文摘The individualization of education and teaching through the computer⁃aided education system provides students with personalized learning,so that each student can obtain the knowledge they need.At this stage,there are a lot of intelligent tutoring systems.In these systems,studentslearning actions are tracked in real⁃time,and there are a lot of available data.From these data,personalized education that suits each student can be mined.To improve the quality of education,some models for predicting studentsnext practice have been produced,such as Bayesian Knowledge Tracing(BKT),Performance Factor Analysis(PFA),and Deep Knowledge Tracing(DKT)with the development of deep learning.However,the model only considers the knowledge component and correctness of the problem,ignoring the breadth of other characteristics of the information collected by the intelligent tutoring system,the lag time of the previous interaction,the number of past attempts to a problem,and situations that students have forgotten the knowledge.Although some studies consider forgetting and rich information when modeling student knowledge,they often ignore student learning sequences.The main contribution of this paper is in two aspects.One is to transform the input into a position feature vector by introducing an auto⁃encoding network layer and to carry out multiple sets of bad political combinations.The other is to consider repeated time intervals,sequence time intervals,and the number of attempts to simulate forgetting behavior.This paper proposes an adaptive algorithm for the original DKT model.By using the stacked auto⁃encoder network,the input dimension is reduced to half of the original and the original features are retained and consider the forgetting memory behavior according to the time sequence of studentslearning.The model proposed in this paper has been experimented on two public data sets to improve the original accuracy.
文摘Today it is proved that the lack of adequate nutritional knowledge leads to problems such as obesity, overweight and increased cardiovascular diseases. However, many obstacles such as poor financial support, lack of time and poor nutritional knowledge can influence achievement of optimal nutrition which is proportional to the level of the athlete's physical activity. The purpose of this study was to determine the level of nutritional knowledge and dietary behavior of athletes in Khorramabad in 2013. Professional athletes of Khorramabad, Iran, with more than one year of regular exercise and at least one course participating in national championships competitions were studied in this cross-sectional, descriptive-analytic study. The samples included 247 athletes aged 17-29 years. Their nutritional knowledge and behavior were measured by the nutritional knowledge and behavior inventory. Results: The results showed a significant difference in nutritional knowledge of athletes by gender and educational level; female athletes have higher nutritional knowledge than male athletes. A gender-dependent difference was found in nutritional behavior; despite their higher nutritional knowledge, female athletes have weaker nutritional behavior than male athletes. However, no significant correlation was found between BMI and nutritional knowledge and behavior of the athletes. Moreover, findings showed that nutritional knowledge and behavior could be significantly different in various sports.

文摘Due to the many types of distributed denial-of-service attacks(DDoS)attacks and the large amount of data generated,it becomes a chal-lenge to manage and apply the malicious behavior knowledge generated by DDoS attacks.We propose a malicious behavior knowledge base framework for DDoS attacks,which completes the construction and application of a multi-domain malicious behavior knowledge base.First,we collected mali-cious behavior traffic generated by five mainstream DDoS attacks.At the same time,we completed the knowledge collection mechanism through data pre-processing and dataset design.Then,we designed a malicious behavior category graph and malicious behavior structure graph for the characteristic information and spatial structure of DDoS attacks and completed the knowl-edge learning mechanism using a graph neural network model.To protect the data privacy of multiple multi-domain malicious behavior knowledge bases,we implement the knowledge-sharing mechanism based on federated learning.Finally,we store the constructed knowledge graphs,graph neural network model,and Federated model into the malicious behavior knowledge base to complete the knowledge management mechanism.The experimental results show that our proposed system architecture can effectively construct and apply the malicious behavior knowledge base,and the detection capability of multiple DDoS attacks occurring in the network reaches above 0.95,while there exists a certain anti-interference capability for data poisoning cases.
文摘Objective: to study the effect of nutrition knowledge, attitude and dietary behavior of medical students before and after clinical nutrition teaching, in order to provide favorable basis for nutrition education of medical students. Methods: 300 students were selected for routine clinical teaching in the first half of 2021 and clinical nutrition teaching in the second half of 2021. After that, questionnaires were used to understand the medical students knowledge, attitude towards nutrition and dietary behavior, and to analyze the effect before and after clinical nutrition teaching. Results: after clinical nutrition teaching, the students awareness rate of nutrition knowledge was significantly higher than before nutrition education, the difference was statistically significant (P < 0.05). After receiving the teaching of clinical nutrition, the students pay close attention to their own nutritional status, which is manifested by the learning attitude of eager to learn nutritional knowledge. Among them, 279 (93.0%) students express that nutritional knowledge is very important, 297 (99.0%) students express that they are willing to take the initiative to learn more nutritional knowledge, and 279 (93.0%) students express that regular eating of snacks will affect their health status. 294 cases (98.0%) of students said it was very important to have breakfast in the morning. However, there were still 180 cases (60.0%) of students who preferred to sleep late rather than eat breakfast early. After the teaching of clinical nutrition, the rates of breakfast, body weight, regular and quantitative meals, fresh vegetables, fruits, bean products, dairy products, nuts, seafood, meat and eggs, carbonated drinks, western fast food, sweets, fried foods, preserved fruits, puffed foods, diet and supper were significantly higher than before (p < 0.05). Conclusion: after receiving clinical nutrition teaching, medical students nutrition knowledge, attitude and eating behavior have been significantly improved, and there is a high probability to control their own diet by using good nutrition knowledge and positive eating attitude, so as to improve their health. It has obvious application significance and is worthy of promotion.

文摘This study assesses the impacts of the COVID-19 pandemic on Chinese residents’food safety knowledge and behavior,and explores the possible influence mechanism,namely,focus on media information.The study is based on internet survey data of 1373 residents in China.A series of econometric models are developed to estimate food safety knowledge and behavior of residents.Both the descriptive and econometric results indicate that the existence of COVID-19 cases in a community has a significantly positive effect on residents’food safety knowledge and behavior.Residents focusing on food safety-related information tend to have higher food safety knowledge and practice food safety behavior.When controlling the variable focused on food safety-related information,the marginal effects of the existence of COVID-19 cases in a community on residents’food safety knowledge and behavior significantly decrease.However,the decrease in consumers’food safety knowledge is quite minor.Hence,the COVID-19 pandemic indeed improves Chinese residents’food safety knowledge and behavior,while focus on food safety-related information is an important mechanism for improving food safety behavior.Moreover,the estimation results of the simultaneous equations model reveal that consumers’food safety knowledge has a significant and positive effect on their food safety behavior.Heterogeneous impacts of the COVID-19 pandemic on residents’food safety knowledge and behavior among different regions and income groups are observed.The findings of this study provide evidence that public health events could enhance residents’safety awareness and behavior,while residents’focus on relevant information plays an important role in improving knowledge and impacting behavior.
文摘Aim To find the relationship of periodontal status and dental caries status with oral health knowledge, attitude, behavior, among professional students in India. Methodology In a cross sectional study, a total of 825 students (males: 577, females: 248) fi'om six professions were surveyed using a self administered structured questionnaire including 41 multiple choice questions and the WHO Oral Health Assessment Form (1997). The data was analyzed using the SPSS version 13.0 to perform the Student's t-test, ANOVA test, Scheffe's test and Chi-square test, linear regression analysis. Results The mean percentage scores of the students for knowledge were 53.25 ±15.05; for attitude 74.97±20.48; and for behavior 59.09 ±18.77. The percentage of students with calculus score was found to be significantly high (43.8%). The percentage of professional students with DMFT〉4 was 14.1% and the percentage of students with decayed teeth was 46.2%. The regression analysis showed that the oral health behavior of the students was dependent on the attitude (P〈0.001), but showed no significant linear relation with the knowledge. Also, that the mean DMFT score was dependent on the oral health behavior (P〈0.05), but showed no significant relationship with the knowledge and attitude of the students. The periodontal status was independent on the knowledge, but showed a significant relationship with attitude and behavior of the students. Conclusion A positive attitude and adherence to good oral hygiene behaviors is associated with better oral health.
文摘The purpose of this study was to discuss the food sanitation knowledge, attitude, and behavior for the employees of university restaurants, and furthermore, to explain the interrelations of these various were occurring at school. A questionnaire survey procedure was used. Each two constructs of food sanitation attitude and behavior were analyzed by factor analysis. Data was analyzed by description, Pearson’s correlation and multiple regression analysis. The correctness rate toward the whole sanitation knowledge of trials was 70%. The overall attitude toward food sanitation was prone to positive and the attitude of employee self-responsibility was superior to the attitude of food sanitation practice. The sanitary guiding behavior was better than the sanitary habit behavior;and there was a significant relationship indicated through Pearson correlation analysis among three various. The sanitation knowledge and sanitation attitude showed a 42.6% predictive power to behavior, the attitude was mediated between knowledge and behavior. The university restaurant employees shared a more pessimistic view toward the benefits of training and the institutions could establish a committee for monitoring food nutrition and sanitation. It provides valuable information for development employees training while seeking to raise school restaurant food safety levels.
文摘The number of Korean students enrolling in universities overseas is rapidly growing. However, these populations are underrepresented in sexuality related research, despite the possibility of sexually risky behavior in overseas university students. We examined the sexual knowledge, attitudes, and behaviors of university students in Korea and studying in the United States. Data were collected—131 Korean students in Korea and in the US using a web-based self-report questionnaire system. Students in the US showed greater total sexual knowledge than students studied in Korea. There were differences in the sexual knowledge, attitude and behaviors according to general characteristics between both groups. Although students in the USA had a higher level of sexual knowledge, both students in the USA and in Korea had a low level of sexual knowledge overall.

文摘Objective To study the relationship between contraceptive knowledge, cognition and behaviors among vocational high school students. Methods A cross-sectional survey was anonymously self-administrated by way of computer to all the 1st graders' among three vocational high schools in a district of Shanghai. Four cognition indicators, including perceived benefits, perceived barriers, perceived risks and self eJficacy were applied according to Health Belief Model. Results The percentage of respondents who reported ever sexual practices and contraceptives use at first sex was 7.01% and 56.64% respectively. Condom (58. 70%) and oral contraceptive pills (27.78%) were used by the majority. Main reasons for non-use were "shy to buy it" (26.53%) and "partner don't want to use any" (18.37%). Proportion of respondents who ever had sex regarded withdrawal and rhythm as effective were 68.35% and 68.42% respectively. Proportion of respondents having sex knew "If a person was infected with STDs, he/she might not have noticeable symptoms" were 22.86%. Proportion of respondents who reported non-use of contraceptives at first sex considered that "infrequent intercourse could not cause a girl pregnant even she had experienced her menstruation" were 40.63%. Proportion of respondents who had ever used condom got full score of knowledge on "how to correctly use condom" were 23,26%. Perceived risks were poorest among four cognition indicators. High level of contraceptive knowledge was connected with high rate of contraceptives use at first sex, whereas high level contraceptive cognition was connected with high rate of contraceptive use both at first and recent sex. Conclusions It is important to provide youth-friendly services as well as message on contraceptives among vocational school students.

文摘A mathematical formula of high physical interpretation,and accurate prediction and large generaliza-tion power is highly desirable for science,technology and engineering.In this study,we performed a domain knowledge-guided machine learning to discover high interpretive formula describing the high-temperature oxidation behavior of FeCrAlCoNi-based high entropy alloys(HEAs).The domain knowledge suggests that the exposure time dependent and thermally activated oxidation behavior can be described by the synergy formula of power law multiplying Arrhenius equation.The pre-factor,time exponent(m),and activation energy(Q)are dependent on the chemical compositions of eight elements in the FeCrAlCoNi-based HEAs.The Tree-Classifier for Linear Regression(TCLR)algorithm utilizes the two exper-imental features of exposure time(t)and temperature(T)to extract the spectrums of activation energy(Q)and time exponent(m)from the complex and high dimensional feature space,which automatically gives the spectrum of pre-factor.The three spectrums are assembled by using the element features,which leads to a general and interpretive formula with high prediction accuracy of the determination coefficient R^(2)=0.971.The role of each chemical element in the high-temperature oxidation behavior is analytically illustrated in the three spectrums,thereby the discovered interpretative formula provides a guidance to the inverse design of HEAs against high-temperature oxidation.The present work demonstrates the sig-nificance of domain knowledge in the development of materials informatics.

文摘Objectives:The purpose of the study was to investigate the nursing students'levels of the knowledge,willingness,and attitudes toward first aid behavior as bystanders in road traffic accident and the related factors.Methods:A total of 475 nursing students were recruited by convenience choosing in Tianjin University of Traditional Chinese Medicine.The nursing students'self-efficacy,core self-evaluation,knowledge,willingness and attitudes toward first aid behavior as bystanders in traffic accidents were investigated with a self-designed questionnaire.Results:The scores of knowledge,willingness,and attitudes toward first aid behavior in traffic accident trauma were 7.51±1.93,15.54±5.03,and 7.73±1.56,respectively.Students who once gained training of first aid showed lower levels of attitude toward first aid behavior than those untrained(t=-2.345,P=0.019).It was found that self-efficacy was correlated to the knowledge(r=0.150,P<0.001),willingness(r=0.182,P<0.004)and attitudes toward behavior of the first aid(r=0.371,P<0.001)among nursing students.Core self-evaluation was correlated to knowledge(r=0.193,P<0.001)and attitudes toward behavior of the first aid(r=0.199,P<0.001).Conclusions:The first aid knowledge among nursing students was not satisfactory.The study suggested that an unsustainable short first-aid training program may bring negative effects.Countermeasures should be taken to ensure both quality and continuity of first aid training.Meanwhile,more attention should be paid to improving the self-efficacy and core self-evaluation of the nursing students.
文摘Objective: To understand the current situation of prehospital first aid knowledge, attitude and behavior of university students in Jingzhou City. Methods: A prehospital first aid knowledge questionnaire and the convenience sampling method were used to survey 307 university students in Jingzhou City. Results: The mean score of prehospital first aid knowledge of university students in Jingzhou City was 12.85 ± 2.643, the mean score of attitude was 50.73 ± 4.114, and the mean score of behavior was 39.05 ± 8.898;There was a statistically significant difference in the scores of prehospital first aid knowledge, attitude, and behavior of university students depending on whether or not they had received prehospital first aid training (P P Conclusion: Jingzhou University students have a positive attitude toward pre-hospital first aid, but the knowledge level and behavior are low, which suggests that the government, society and the school should create good conditions to promote the improvement of pre-hospital first aid knowledge and ability.
文摘This cross-sectional descriptive study assessed general environmental health literacy among students focusing on their knowledge, skills, attitudes and behaviors regarding the environmental health, stewardship, and sustainability, using a questionnaire consisting of 35 core questions from the Centers for Diseases Control (CDCs). Students (N = 185) from three high schools in the district were asked through their class teachers to voluntarily complete the questionnaire. Results indicated that about 41% (n = 77) of the students lacked knowledge regarding potential sources of radiation exposure and 70% (n = 133) lacked knowledge regarding radon gas being the number one risk factor for lung cancer among non-smokers. Additionally, the ANOVA test indicated significant knowledge differences among school location. Students in school #1, located in the most affluent area, had significantly higher knowledge scores (M = 4.39) than school #2 located in a moderately affluent area (M = 3.50). Furthermore, we found significant differences in ethnicity on the environmental health attitude of the high school students. Black students reported lower positive environmental health attitude (M = 29.86) than White students (M = 32.63), Hispanic students (M = 32.33) and Asian students (M = 33.84). These findings demonstrated knowledge deficiency in some key areas in environmental health particularly the environmental diseases and conditions caused by manmade hazards such as pesticides, chemicals, radiation, air, water, and soil pollution. Targeted educational interventions to increase awareness and understanding of health effects, exposure to environmental hazards and carcinogens as well as risks associated to direct exposure as in this study, radon and radiation, should be provided to high school students. Practical education through tours where students can observe directly and participating in laboratory experiments could empower the students to translate this knowledge into positive environmental health behaviors and practices now and in the future.
