  • Background: Breast and cervical cancers are the most common types of cancer in women worldwide. Previous studies in Asia have shown that related knowledge and awareness is low among female university students. The goal of this study was to assess breast and cervical cancer knowledge, practices, and awareness among female university students in Samsun,Turkey. Materials and Methods: This research was a cross-sectional survey of female university students using a self-administered. questionnaire to investigate participant awareness and knowledge of breast and cervical cancer. A total of 301 female university students participated. Descriptive statistics and chi square tests were used for data analysis. Results: The mean age of the participants in this study was $22.0{\pm}5.91$ years. Regarding family history, 89.7 % of the students had no known familial history of breast cancer. Students (65.4%) had knowledge about breast self examination and 52.2 % of them had performed breast self examinationm while 55.1% of them had knowledge about prevention of cervical cancer. Conclusions: Although the results are preliminary, the study points to an insufficient knowledge of university students in Samsun about breast and cervical cancer.

  • The purpose of this study is to identify the basic scientific knowledge of in- and pre-service elementary school teachers, specific areas having insufficient knowledge and the reason for the lack of understanding. For the study, we analyzed the survey asking basic scientific knowledge to in-service elementary school teachers within an urban communities and pre-service elementary school teachers enrolling the first, the second and the third year in National University of Education. The results shows that there is the lack of understanding about scientific knowledge such as boiling points, perihelion, substances, and elements, which elementary school teachers should have exactly known. With regard to the age, an effort is required to increase scientific knowledge of the in-service teachers in 50's, compared to those in 20s' and 30s'. In the pre-service teachers, the average in the third year was significantly higher than that in the first and second year. Regarding the major background in high school, both of in- and pre-service teachers who completed the science course showed significantly higher average than those who completed the liberal arts course. In addition, regarding the major in the university, the average of the group with science and engineering major was higher than that of the group with other majors.

  • Background: Knowledge and individual perceptions about adverse effects of all forms of tobacco exert direct influence on the level of tobacco consumption in various socio-demographic groups. The objective of this study was to determine the nature, extent and demographic correlates of knowledge, attitudes and perceptions of use of tobacco among adults in low and middle income countries. Materials and Methods: The Global Adult Tobacco Survey, conducted in fourteen different countries from 2008-2010, was sourced for the data analyzed in this study. Descriptive statistical analyses were conducted to determine the prevalent knowledge and individual perceptions amongst adults about all forms of tobacco consumption. Results: There was relatively high awareness about the harmful effects of smoking tobacco with main awareness being about its relationship with lung cancer (>90% in most countries). In contrast, there was relatively low awareness about harmful effects of smokeless tobacco (< 90% in all countries except India and Bangladesh), and observed correlation of smoking tobacco with heart attack (40.6% in China, 65.1% in India) and stroke (28.2% in China, 50.5% in India). Conclusions: A large proportion of adults living in low and middle income countries possess adequate knowledge about smoking tobacco but have inadequate awareness as well as false perceptions about smokeless forms of tobacco. Popular beliefs of inverse relationships of tobacco consumption with knowledge, attitudes and perception of populations towards tobacco are challenged by the findings of this study.

  • Background: To assess the effect of an information leaflet on the level of Chinese youth's knowledge about hepatitis B and hepatocellular carcinoma (HCC), the most common type of primary liver cancer (PLC). Materials and Methods: A total of 500 students, from two universities in the Chaoshan area of China, were randomly divided into an intervention group of 280 participants and a control group of 220. Baseline knowledge of HCC and hepatitis B was evaluated by questionnaire interview. Subsequently, only the intervention group was given an information leaflet of HCC and hepatitis B. Three months later, the two groups were contacted for a second interview. Changes in knowledge from baseline of HCC and hepatitis B were compared between the two groups. Results: There was no statistically significant difference in mean PRE-questionnaire scores between the intervention and control groups. However, the mean POST-questionnaire score was significantly higher in the intervention group after the intervention. The leaflet had the greatest effect on the participants' questionnaire score, and raised their level of knowledge about HCC and hepatitis B. Conclusions: The information leaflet intervention is significantly effective in improving the knowledge of HCC and hepatitis B among the youth.

  • A simulated realistic virtual environment is inhabited by autonomous cyber-humans who play the roles of agents in events. A key element, which enables this realism, is the historical context formed by time and space. A knowledge-representation scheme, composed of both spatial and temporal aspects needed by the agent to respond to dynamically changing situations, is essential for the design of a realistic virtual agent. In this work, spatial and temporal aspects of dynamic situations in the virtual environment have been formalized as a key component of our knowledge-representation scheme. This scheme provides a mathematical framework to construct realistic virtual situations that change with time, and background knowledge for agents in the simulated environment to deduce new pieces of information and plan against changing situations.
