In this study, a survey was conducted of students in grades 7 through 12, student teachers enrolled in their senior year at teachers' colleges, and science teachers. Subjects were surveyed on their conceptions of phenomenon related with dissolution, saturation, and extraction. The models and analogies used by student teachers and science teachers to explain dissolution were sought. The highest percentage of students thought of dissolution as a phenomenon in which particles broke into the spaces between other particles. The models or analogies used by the highest percentage of science teachers were similar. They generally conceived of dissolution phenomenon through what we call the 'space conception'. A conception of dissolution phenomenon as 'hydration through attraction of solvent and solute' was held by more student teachers than science teachers; there were some differences, however, according to their academic background. The percentage of teachers professing this view decreased when they attempted to explain the process of extraction of matter in a solution after other matter had dissolved or after the solution was cooled, indicating that the 'hydration' conception was not firmly established in the student teachers' cognition. Therefore, it can be inferred that the conceptions of dissolution as 'hydration' were transformed into the conceptions of dissolution as 'space' after teaching dissolution phenomenon as practicing teachers. This finding should be considered in teacher-training courses.

Acceptance and Commitment Therapy (ACT) is a functional contextual intervention approach based on the behavioral theory on human language, which views human suffering as originating in psychological inflexibility fostered by cognitive fusion and experiential avoidance. Thus, the goal of ACT is to enhance psychological flexibility using six core processes including acceptance, cognitive defusion, self-as-context, contact with present moment, values clarification, and committed action. Recent clinical trials have suggested the efficacy for ACT in the treatment of various mental illness and psychological distress. The aim of this review is to offer more knowledge and better understanding of ACT by presenting its underlying principle and an overview of the research field.

Various new technologies and aiding instruments are always being introduced for the betterment of the challenged. This project focuses on aiding the mute in expressing their views and ideas in a much efficient and effective manner thereby creating their own place in this world. The proposed system focuses on using various gestures traced into texts which could in turn be transformed into speech. The gesture identification and mapping is performed by the Kinect device, which is found to cost effective and reliable. A suitable text to speech convertor is used to translate the texts generated from Kinect into a speech. The proposed system though cannot be applied to man-to-man conversation owing to the hardware complexities, but could find itself very much of use under addressing environments such as auditoriums, classrooms, etc

The goal of this study is to deepen the understanding of robot business and application, and examine the relationships and development trends of robot evaluation scales. Through interactive mapping, 113 types of robot data samples were realized to be placed on seven evaluation scales and reference on specific information of each items were allowed. Also, by examining the robot development trends among different countries through interactive mapping, the trends could be largely divided into American, European, Japanese, and Korean. Throughout various parts of the evaluation scale, American and European views were found to consider robots mainly as tools. On the other hand, Japanese and Korean views considered robots as a 'partner' or 'neighbour' and were working to satisfy these aspects.

Public bicycle system (PBS) is a new emerging and popular mode of public transportation. PBS data can be adopted to analyze human movement patterns. Previous work usually focused on specific scales, and the relationships between different levels of hierarchies are ignored. In this paper, we introduce a multi-scale and interactive visual analytics system to investigate human cycling movement and PBS usage condition. The system supports level-of-detail explorative analysis of spatio-temporal characteristics in PBS. Visual views are designed from global, regional and microcosmic scales. For the regional scale, a bicycle network is constructed to model PBS data, and an flow-based community detection algorithm is applied on the bicycle network to determine station clusters. In contrast to the previous used Louvain algorithm, our method avoids producing super-communities and generates better results. We provide two cases to demonstrate how our system can help analysts explore the overall cycling condition in the city and spatio-temporal aggregation of stations.

Purpose: This article aims to investigate the influence of pricing and distribution on the level of satisfaction and purchase decisions among consumers of pharmaceutical products in Kazakhstan. Research design, data, and methodology: A mixed-methods research design was utilized, incorporating primary and secondary data. Primary data were collected through a survey administered to customers across various pharmacy types, with 100 valid responses analyzed. Secondary data involved an extensive review of existing literature and analysis of national statistics concerning the pharmaceutical market trends from 2008 to 2022. Results: The results reveal a complex relationship between price perceptions and customer satisfaction. A significant segment of the population views current drug prices as high, which affects their satisfaction levels and purchase decisions. The study also highlights the importance of service quality in enhancing customer satisfaction, suggesting that service improvements could mitigate some of the negative perceptions of pricing. Conclusions: This research contributes to the limited but growing body of knowledge on the impact of pricing strategies on consumer satisfaction in the pharmaceutical sectors of developing countries like Kazakhstan. Focusing on economic and behavioral aspects, this study provides a more holistic understanding of the factors driving consumer satisfaction and purchase behaviors in this critical sector.

It is well known that high school girls' mean achievement levels in science tests are lower than high school boys' and that fewer women than men are employed as scientists and engineers pursue scientific careers. Many research attributed the sex difference in achievement level in science and the lack of women in science among others, to the experiential differences in scientific activities and the differences in attitudes toward science and scientists. Therefore, the study had its object to examine the sex difference by high school students in scientific experience and attitudes toward science and scientists. The differences in science experiences were identified at eight schools over rural and urban areas in Kangwon province. Science activities surveyed included use of experimental materials and instruments, observation of scientific phenomena, and extracurricular scientific activities. Attitude scale contained the nature of science, scientific research methods and philosophical views held by scientists. The study found sex differences in scientific experiences and attitudes. i. e.: fewer high school girls than boys had experience with scientific activities, especially with extracurricular activities; however, girls had more positive attitude toward science and more active desire to participate in science. Consequently, the study implies that, in order to narrow the gaps between achievement levels for boys and girls, science education should take consideration of the sex difference in experiences with and attitudes toward science.
