This describes the level of knowledge and attitudes about HIV and their related factors among Cambodian adolescents. A cross-sectional design was used to examine the knowledge and attitude of 463 Cambodian high school students using HIV-KQ-18 (HIV-Knowledge Questionnaire-18) and HIV/AIDS Behavior Surveillance Survey Index (measuring attitude about HIV). The majority of the adolescents had a relatively low level of overall HIV knowledge (6.70 ± 3.66 (range: 0-16)) and held a very negative attitude (1.92 ± 0.87 points (range: 0-4)) toward the disease. Using multiple regression analysis, being male (β = 0.28, p < 0.001) and using YouTube as a social network service (β = 0.33, p = 0.035) were found to be independent factors associated with higher level of HIV knowledge. Study findings suggest the importance of informing policymakers and school nurses about the need to develop a and require a culturally sensitive specific health education program on HIV for Cambodian adolescents.

Objectives: The purpose of this study was to explore the effectiveness of the STEAM (Science, Technology, Engineering, Arts, and Mathematics) education program on the use of specific food groups in improving nutrition-related knowledge and attitude, dietary behavior, creative problem solving, and STEAM attitude. Methods: We selected two classes at a kindergarten in Jeollabuk-do, South Korea. A total of 44 kindergarteners from the two classrooms participated in this study. The experimental group and the control group were formed with 22 students each. The experimental group attended 11 STEAM classes on the use of the grain, fruit, and milk food groups. First, we performed the paired t-test to examine changes from pre-to-post classes for both groups. Then, we used ANCOVA to compare post-test scores between the experimental and control groups with the adjustment of pre-test scores. Results: The results demonstrate that the STEAM education program on the use of the food groups significantly improved (1) nutrition-related knowledge and attitude, and dietary behavior (P < 0.001), (2) creative problem solving (P < 0.001), and (3) STEAM attitude (P < 0.001) in the intervention group when compared with the control group. Conclusions: The STEAM education program on the use of food groups is effective in enhancing nutrition knowledge and attitude, dietary behavior, creative problem solving, and STEAM attitudes among kindergarten students.

Background: The present study aimed to gather basic data for the development of an educational tuberculosis prevention program for prospective dental hygienists by understanding the level of knowledge, attitudes, and preventive behaviors related to tuberculosis for students in the Department of Dental Hygiene, who need preventive access to tuberculosis infection. Methods: The present study used a self-reported questionnaire on knowledge, attitudes, and preventive behaviors regarding tuberculosis, which was administered to dental hygiene students attending D University located in D city. Results: The average knowledge regarding tuberculosis was 16.17 ± 6.14, out of 30 points. Attitude regarding tuberculosis averaged 48.59 points (± 4.46), out of 60 points, and the degree of preventive behavior was 46.29 points (± 5.0), out of 60 points. Third year students ranked highest for knowledge regarding, attitude toward, and infection prevention behaviors of tuberculosis, compared to those in their first or second year (F = 7.20, p = 0.000). Those who had experienced tuberculosis themselves or with their relatives had higher attitudes toward tuberculosis than those who did not (F = 2.32, p = 0.02). Additionally, the higher the knowledge (β = 0.209, p = 0.004) and attitude (β = 0.425, p = 0.000) about tuberculosis, the higher the level of tuberculosis infection prevention behavior. Conclusion: Based on the results of the present study, it appears to be necessary to provide practical education to ensure that all students in dental hygiene are equipped with knowledge about tuberculosis, and that as a dental hygienist in carrying out dental hygiene management with a changed attitude, the act of preventing tuberculosis infection can be appropriately performed.

Mobile devices have become attractive learning devices for education. The digitalization of the higher education system in Sri Lanka by 2020 is part of the government's effort to modernize and enhance the country's overall education system particularly in view of the COVID-19 pandemic. Theoretically, this study contributes to the M-Learning model in higher education institutions via the integration of literature on technology adoption (TAM and UTAUT) with the variables of Perceived Usefulness, Perceived Ease of Use, Attitude, Effort Expectancy, Social Influence, and Facilitating Condition. The attitude towards M-Learning amongst higher education students was gauged via an online questionnaire survey. The convenience sample comprised 344 students from the Advanced Technological Institutes (ATI) in Batticaloa District, Sri Lanka. Descriptive statistics, a measurement, and structural model, and hypotheses testing were used to analyze the derived data. The findings indicate that mobile learning is significantly affected by perceived ease of use, social influence, effort expectancy, and facilitating condition, but negatively affected by attitude and perceived usefulness. The exhaustive literature review revealed that there are very few M-Learning studies related to digital learning in the context of higher education in the Batticaloa district.

A well-known difficulty in attitude estimation based on inertial measurement unit (IMU) signals is the occurrence of external acceleration under dynamic motion conditions, as the acceleration significantly degrades the estimation accuracy. Lee et al. (2012) designed a Kalman filter (KF) that could effectively deal with the acceleration issue. Ahmed and Tahir (2017) modified this method by adjusting the acceleration-related covariance matrix because they considered covariance modeling as a pivotal factor in the estimation accuracy. This study investigates the effects of covariance modeling on estimation accuracy in an IMU-based attitude estimation KF. The method proposed by Ahmed and Tahir can be divided into two: one uses the covariance including only diagonal components and the other uses the covariance including both diagonal and off-diagonal components. This paper compares these three methods with respect to the motion condition and the window size, which is required for the methods by Ahmed and Tahir. Experimental results showed that the method proposed by Lee et al. performed the best among the three methods under relatively slow motion conditions, whereas the modified method using the diagonal covariance with a high window size performed the best under relatively fast motion conditions.

Power bloggers have become one of the most important resources of blog service companies, and only those who attract and secure power bloggers will be able to have competitive edge and profitability in blog related businesses. This study examines the effects of technology acceptance factors and economical factors on the loyalty of power bloggers. The analysis results show that the usefulness, power of social influence and enjoyment positively affect the attitude and intention to continuous use. The relationship between the attitude and intention to continuous use is demonstrated as significant. The economical benefit exhibits weakly positive influence on the attitude to blogging, but not on the intention. This indicates that although many power bloggers receive economic benefits through their blogging activities, such economical benefits do not have big impact on their activities and the intention to use. The blog service providers may use the analysis results when developing new blog services. In particular, the usefulness, which is often considered as one of the most important factors in the success of the blogosphere, is found to have less impact than the enjoyment among power bioggers. This is because blog users, especially power bloggers, use the blog not for a specific purpose or for generating a special product; most of them use the blog to satisfy their own personal desires. When developing blog services, therefore, it is important to cater to the users' enjoyment and their psychological compensation. What is surprising is that the effect of the economical factor is not ad significant as one might have expected. This implies that the new blog services that provide profit sharing or advertising revenue sharing may not be as successful as one would have hoped for in maintaining the loyalty of power bloggers.

KAIST' is the TV drama which has portrayed modem science & technology and the life of scientists & engineers for about one and half year. The purpose of this study is to appraise the drama 'KAIST' as an informal science learning. Using the interesting materials such as soccer robots, computer systems and satellites, the drama arouse students' interest and frequent watching. In general, the drama 'KAIST', as a source for informal science learning, played a positive role: it showed the image of scientists who have humane and sociable character being different from the students' image of real scientists, and changed positively the students' science-technology related attitudes, especially the attitudes towards scientists/engineers, science/technology, and the social nature of science/technology. Teachers commented that the drama 'KAIST' might arose students' interest in science, but the made-up contents and the genius-like characters could cause negative educational effects.

Previous studies stated that low carbon innovation performance could be influenced by government regulations and the green market, which is the new trend of consumer consumption in the present time, mainly focusing on external factors. Before study augured that low carbon innovation performance could be driven by internal and external factors of cooperation such as institutional pressure, stakeholder pressure, and innovation resources. However, the study of green transformational leadership and organizational environmental culture on low carbon innovation performance is rare, especially in Chinese manufacturing, as well as the effect of influencing factors of TPB model: environmental attitude, subjective norm, and perceived behavior capability on low carbon innovation performance. Previous studies mostly used the TPB model for predicting individual behavior. This study established a theoretical model combining the TPB model with green transformational leadership and organizational environmental culture of Chinese automobile manufacturing on low carbon innovation performance. This study consists of two sections of research methodology: section 1 related to questionnaire design and data collection. We established a questionnaire and distributed it online, targeting responses from the managerial level working in Chinese automobile manufacturing. Eventually, 155 valid questionnaires were used for analysis. Section 2 involved data analysis using statistical software. Reliability and data validity was examined by reliability analysis and factor analysis. Correlations and convergent validity analyses were applied, and structural equation modeling was conducted to test the proposed hypotheses. The findings indicated that green transformational leadership, organizational environmental culture, and essential factors of TPB model; environmental attitude, subjective norm and perceived behavior capability positively affect low carbon innovation performance. In addition, the indirect effect of green transformational leadership was tested and found that organizational environmental culture and TPB factors mediated the relationship between transformational leadership and low carbon innovation performance.

Purpose : The purpose of this study was to investigate dual gender identity, masculine gender identity, feminine gender identity, undifferentiated gender identity with related to Sex, home environments, parental child-rearing attitude of warmth, parental child-rearing attitude of control, role division of parents and determine predictors for dual gender identity. Method : Study subjects were $6^{th}$ grade of primary students with 2,118. Data was collected from Oct to Nov 2003 by using structured questionnaire. Results : ${\cdot}$ Among the children, 345 had masculine gender identity, 529 had feminine gender identity, 526 had undifferentiated gender identity, and 718 had dual gender identity. ${\cdot}$ There were significant differences in the children's sex, mother's age, father's age, mother's educational level, father's educational level, existence of mother's job, father's job, social economic status, sex of siblings, mother's job satisfaction, family structure, family atmosphere, child-rearing attitude(warmth and control), role division of parents($p{\leq}0.001$) among 4 groups. ${\cdot}$ The significant predictors for dual gender identity were children's sex (OR = 0,196, P =0.001), father's age(OR = 31.053, p = 0.020), mother's educational level(OR = 43,980, p = 0.001), father's job(OR=27.465, p = 0.001), social economic status(OR=O.941, p=0.001), sex of siblings(OR = 0.329, p = 0.005), mother's job satisfaction(OR = 0.673, p =0.001), family structure(OR = 0.887, p = 0.001), family atmosphere(OR = 23.786, p = 0.001), parental Child-rearing attitude of warmth(OR = 8.043, p = 0.001) and child-rearing attitude of control(OR = 0.666, p = 0.005), role division of parents(OR = 3.009, p = 0.001). Conclusions : These findings suggest the necessity of broad understandings about factors which influence dual gender role, and construction of combinative model. Also they suggest parent education for establishment of children's dual gender identity.
