The students’ learning results in Biology are influenced by two factors, namely internal and external factors. The internal factors that can influence learning results are learning style, learning independence, and learning interest. The research aims to discover the relation of learning style, learning independence and learning interest with Biology learning results of the students at SMAN 1 Tonra in Bone District.The research is ex post facto. The population of the research were the students of class IPA at SMAN 1 Tonra in Bone District of academic year 2016/2017. The samples were 194 students taken by using stratified random sampling technique. Data were collected by employing questionnaire and documentation. The data of the research were analyzed by using descriptive and inferential statistics techniques. The results of the research reveal that (i) the students’ learning style tends to be in visual type, (ii) the students’ learning independence is in high category, (iii) the students’ learning interest is in high category, (iv) the students’ Biology learning results is in high category, (v) there is strong relation between learning style and the students’ Biology learning results, (vi) there is fairly strong relation between learning independence and the students’ Biology learning results, (vii) there is strong relation between learning interest and the students’ Biology learning results, and (viii) there is very strong relation between learning style, learning independence, and learning interest toword Biology learning results of the students at SMAN 1 Tonra in Bone District.
Abstract. This study aims to extract the essential features of Photoplethysmography (PPG) signal of men and women in healthy subjects using Power Spectral Density (PSD) and Detrended Fluctuation Analysis (DFA). A PPG instrument was used to obtain the PPG signal of 15 men and 15 women. Using PSD, four frequency bands were selected to divide the spectral component. The areas within the frequency bands relative to the total area were computed as features of the signals. Furthermore, using DFA, the average fluctuation F(w) was computed. The feature extraction using this technique produced 4 features from different windows. Hurst exponent was calculated to analyse the characteristics of the time series. For comparing the feature extraction techniques, Heart Rate (HR) and Peak to Peak Interval (PPI) were computed. Additionally, F and T tests for all techniques were computed to determine the differences between man and woman features that have been gathered using these two techniques. The results indicate that the features of PPG signals of men and women using PSD and DFA were significantly different. In order to evaluate the results, a clustering analysis was applied to the results using K-means clustering technique. The clustering plots show that the features were well distributed into the two groups.
The community diseases prevention behaviors assumed influenced by knowledge of infectious disease, hygiene and health knowledge, motivation and of behaviors aof disese prevention than influence by attitude prevention of infectious diseases. This study aimed to examine the effect of variable knowledge infectious disease, hygiene and health knowledge, motivation prevention of infectious diseases, an attitude towards the behavior of infectious disease prevention. The research was conducted in Maros Regency, South Sulawesi Province with a quantitative approach survey method, which uses the quesioner that measure all variables mentioned above. The population in this study is the district's communities sampled from the Turikale, Mandai and Bantimurung sub-District of 200 respondents. The Structural Equational Modeling (SEM) is used to assess significant relation between all variable. The results showed that infectious disease prevention knowledge, attitudes prevention of infectious diseases affect the community behavior of infectious disease prevention, while knowledge of hygiene and health, communicable disease prevention motivation does not affect the behavior of infectious disease prevention. These results, suggest that knowledge of hygiene and health and prevention of infectious diseases motivation of concern that the incidence of infectious diseases, especially pulmonary tuberculosis, dengue fever, and diarrhea in Maros is not increased.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
