In this paper, we use scratch to design and develop non-formal learning experiences that are linked with contents of secondary science textbook to educational programs. The goal of this paper is to develop a convenient and interesting program for non-formal learning in a learning environment using various smart device. Theoretical approaches to mobile education, such as smartphones, and smart education support policies continue to lead to various research efforts. Although most of the smart education systems developed for students who have difficulty in academic performance are utilized, they are limited to general students. To solve the problem, the learning environment was implanted by combining the scratch, which is an educational programming that can be easily written. The science education program proposed in this paper shows the result of process of programming using ICT device using scratch programming. In the evaluation stage, we were able to display the creations and evaluate each other, so that we could refine them more by sharing the completed ideas.

Factory monitoring systems are gaining importance in wide areas of industry. Especially, there have been many efforts in implementation of vibration measurement and analysis for monitoring the status of rotating machines. In this paper, a digital signal processor (DSP) based monitoring system dedicated to the vibration monitoring and analysis on rotating machines is discussed. Vibration signals are acquired and processed for the continuous monitoring of the machine status. Time domain signals and fast Fourier transform (FFT) are used for vibration analysis. All of the signal processing procedures are done in the DSP to reduce the production and maintenance cost. The developed system could also provide remote and mobile monitoring capabilities to operator via internet connection. This paper describes the overview of the functional blocks of the implemented system. Test results based on signals from small-size single phase motors are discussed for monitoring and defect diagnosis of the machine status.

This article aims to discuss the barriers hindering cancer patients from receiving early palliative care, which has been demonstrated to be more effective in improving quality of life and controlling symptoms. Specifically, there are barriers in four aspects of delivering early palliative care. First, the difficulty of starting discussions about early palliative care and the lack of adequate appointment time can impede communication between oncologists and patients and their family members. Second, determining the timing of referral and deciding upon and applying a standard for referral can be barriers in the process of referral from oncology to palliative care. Third, palliative care patients and their family members can face difficulties regarding in what format and by whom the services will be delivered. Fourth, biases, misinformation, and inaccurate beliefs can be barriers in the process of patients and their family members accepting care. In order to facilitate early palliative care, research and policy regarding these barriers are necessary, along with efforts made by medical staff.

This study investigates the effectiveness of tailored anti-smoking campaigns by examining the interplay between self-construals, cigarette types, and stages of change in smoking cessation efforts. Focusing on both combustible cigarette and electronic cigarette users, the research explores how messages framed around either independent or interdependent self-construals influence attitudes and intentions to quit smoking. The findings indicate that in the early stages of cessation, combustible cigarette users respond more positively to messages emphasizing independent self-construals, which highlight personal health risks. Conversely, in the later stages, e-cigarette users are more receptive to interdependent self-construal messages that stress the broader impacts of smoking. We emphasize the importance of aligning smoking cessation messages with the psychological profiles and cessation readiness of different smoker groups. We offer theoretical and empirical insights for enhancing the effectiveness of public health campaigns.
