A questionnaire of four sections was conducted with university students during the research. The survey was organized as; personal information at the first section, environmental knowledge test at the second section, attitudes towards environment at the third section and behavioral scales at the fourth section. The research consisted of students studying in Agriculture Department in Northern Cyprus Universities in spring semester of 2015-2016 academic year, as the sample consisted of 114 female, 186 male, totally 300 students studying in fall semester of the same academic year. The data obtained during the application were analyzed in SPSS 20.00 package program. Whether the attitudes and behaviors’ of students towards environment differed in terms of independent variables of the research were investigated by using t-test for two variable features and Anova, Wilkis Lambda, Manova test for more than two features. According to the findings of the research, the attitudes and behaviors’ of university students towards environment do not differ according to educational level, income level of their parents and whether they received training about environment.","PeriodicalId":72412,"journal":{"name":"Biostatistics and biometrics open access journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44467720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental unit could be a person or an animal. In repeated measurement design each subject is measured before and one or several times after an intervention. Areas where RMDs are widely used include medicine, pharmacology, animal sciences and psychology. A characteristic feature of RMD is that the effect which a treatment has during its period of application (its direct effect) may persist into the following period(s). If the effect persists only into the immediately following period, the effect is called the first-order residual effect or residual effect. The choice of RMD must be made in a way that the treatments can be efficiently compared after allowing for the residual effects. In this paper circular balanced and strongly balanced repeated measurement designs are constructed to extend the work of Iqbal and Tahir [1] for v ≤ 100 in 3 periods.","PeriodicalId":72412,"journal":{"name":"Biostatistics and biometrics open access journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47760534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Use of statistical techniques becomes inevitable to validate the predictive power of the biomarkers and also to ensure the reproducibility of results. Identification of statistically significant covariates and competing risks is another important aspect of any biostatistical study for understanding disease progression. This paper attempts to review some useful statistical and biostatistical techniques being utilized in the study of dementia, Alzheimer’s disease (AD) in particular, and also proposes some potentially reliable techniques which can be helpful in critically examining the complexities involved in brain activities of AD patients and its association with other pathological and physical changes in the patients. This paper concludes by proposing an objective-wise methodological structure for biostatistical analyses of AD.","PeriodicalId":72412,"journal":{"name":"Biostatistics and biometrics open access journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68370880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Streaming multimedia is an Internet data transfer method that facilitates the transfer of audio and video files from computer to computer in a “stream.” Streamed media packets can be played as soon as the data starts arriving at the receiving computer—users do not have to wait until the full file has been downloaded. Streaming audio has been more successful than video, which has generally been limited to small picture sizes or low resolution (grainy) video Paperions, but as the bandwidth increases, higher quality, full-screen video becomes possible. When a sound file is to be prepared for streaming, it is compressed to reduce the overall size of the file. Streaming audio is currently being used as a supplement to classroom-based and online course delivery, usually in the form of pre-recorded lectures, interviews with guests, student Papers, samples of student classroom interaction, or sound bytes of content relevant to the course of study. When implemented wisely, video can alleviate the “page-turning” boredom of many online courses [1]. The multimedia based e-learning content of this site is protected by data encryption, as more users come to understand the internet’s open nature and the dangers of web surfing, Today’s web browsers automatically encrypt text when making a connection to a secure server. This prevents intruders from listening in on private communications. Even if they are able to capture the message, encryption allows them to only view scrambled text or what many call unreadable gibberish. Upon arrival, the data is decrypted, allowing the intended recipient to view. Without this security mechanism, information transferred over the internet can be easily captured and viewed by anyone listening. Data encryption refers to mathematical calculations and algorithmic schemes that transform plaintext into cyphertext, a form that is non-readable to unauthorized parties. The recipient of an encrypted message uses a key which triggers the algorithm mechanism to decrypt the data, transforming it to the original plaintext version. Another security mechanism implemented in this Paper is the Online face recognition which facilitates a user who is equipped with a display device. Our online singleimage face recognition system is implemented using still imagebased algorithms [2].
