(1) Background: Bioreactors mimic the natural environment of cells and tissues by providing a controlled micro-environment. However, their design is often expensive and complex. Herein, we have introduced the development of a low-cost compression bioreactor which enables the application of different mechanical stimulation regimes to in vitro tissue models and provides the information of applied stress and strain in real-time. (2) Methods: The compression bioreactor is designed using a mini-computer called Raspberry Pi, which is programmed to apply compressive deformation at various strains and frequencies, as well as to measure the force applied to the tissue constructs. Besides this, we have developed a mobile application connected to the bioreactor software to monitor, command, and control experiments via mobile devices. (3) Results: Cell viability results indicate that the newly designed compression bioreactor supports cell cultivation in a sterile environment without any contamination. The developed bioreactor software plots the experimental data of dynamic mechanical loading in a long-term manner, as well as stores them for further data processing. Following in vitro uniaxial compression conditioning of 3D in vitro cartilage models, chondrocyte cell migration was altered positively compared to static cultures. (4) Conclusion: The developed compression bioreactor can support the in vitro tissue model cultivation and monitor the experimental information with a low-cost controlling system and via mobile application. The highly customizable mold inside the cultivation chamber is a significant approach to solve the limited customization capability of the traditional bioreactors. Most importantly, the compression bioreactor prevents operator- and system-dependent variability between experiments by enabling a dynamic culture in a large volume for multiple numbers of in vitro tissue constructs.

Weed infestation happens when there is intense competition between rice and weeds for light, nutrients and water. These conditions need to be monitored and controlled to lower the growth of weeds as they affected crops production. The characteristics of weeds and rice are challenging to differentiate macroscopically. However, information can be acquired using a spectral signature graph. Hence, this study emphasises using the spectral signature of weed species and rice in a rice field. The study aims to generate a spectral signature graph of weeds in rice fields and develop a mobile application for the spectral signature of weeds. Six weeds were identified in Ladang Merdeka using Fieldspec HandHeld 2 Spectroradiometer. All the spectral signatures were stored in a spectral database using Apps Master Builder, viewed using smartphones. The results from the spectral signature graph show that the jungle rice (Echinochloa spp.) has the highest near-infrared (NIR) reflectance. In contrast, the saromacca grass (Ischaemum rugosum) shows the lowest NIR reflectance. Then, the first derivative (FD) analysis was run to visualise the separation of each species, and the 710 nm to 750 nm region shows the highest separation. It shows that the weed species can be identified using spectral signature by FD analysis with accurate separation. The mobile application was developed to provide information about the weeds and control methods to the users. Users can access information regarding weeds and take action based on the recommendations of the mobile application.

The rapid development of mobile Internet technology and the wide spread of smart terminals have brought opportunities for the transformation of power grid business model. Compared to the non-real-time information, the real-time and running data of dispatch and control domain is easy to be intercepted and cracked. To solve this problem, this paper presents a new approach to mobile application security framework for the power grid control field. It is to realize secondary encryption by using the method of MD5+AES mixed encryption algorithm and combining the time stamp in real-time data transmission process. At the same time it is to prevent cross-border operations and brute force by using Token authentication and Session technology. China EPRI safety test results show that the application of the framework significantly improves the integrity, safety and reliability of real-time data in power grid control.

This empirical study was conducted to measure visitors’ experiences with a mobile guide application at Kuching Orchid Garden (KOG). A between-group experimental design with 114 participants was conducted to test three groups;(1)a group using the mobile guide application as an information aid,(2)a control group (with no information aid), and(3)a group using pamphlets to explore the KOG. The Museum Experience Scale (MES) was used to evaluate visitors’ experience for all participants, whilst the Multimedia Guide Scale (MMGS) was used to evaluate the visitors’ experience with the mobile guide group. The most notable result from the Museum Experience Scale (MES) showed an impact on the visitors in terms of knowledge and learning when using the mobile guide application. However, the study found that enhancing visitors experience goes beyond simply providing interactive technologies in public settings to aid with information delivery. A limitation was providing relevant information in a timely and seamless manner due to inaccuracies of mapping between physical and digital environments. Future works should consider beacons and other Bluetooth low energy (BLE) technology to address the issues with location based devices. It is also important to highlight that the use of one’s own device had a significant impact on learnability and control of the device, thus suggesting that the BYOD concept should be widely used in informal educational settings implementing mobile guide applications. The use of MES and MMGS informs future researches with an understanding of the different dimensions of visitors’ experiences with mobile guide technology in public spaces to inform mobile application development that may further boost visitors’ engagement, emotional connection, and meaningful experience.

Managing water consumption is important for life preservation. Knowing water consumption at homes can have a great impact on water saving. There is a global water crisis due to increasing population growth, climate change, increasing consumption. Giving a report about the state of the planet’s water, especially in developing countries, the report describes the outlook for future generations as worries. To visually check water taps in the house consumes time and requires a family member to be at the house. To remotely do so, we propose a system that monitors, alerts the user and allows the user to control the water flow through taps whenever there is an unusual reading of the water usage at home. The Water Flow Monitoring and Controlling System is an android- based mobile application. It is equipped with external hardware to sense a tap’s water flow rate and control which means turning on or off the water supply line whenever necessary. Registered users can login and view their house’s current water flowage from the mobile application. The external hardware updates the water flow rate at every specified time to a database through the Internet connection. If the users decide to turn on or off the water supply taps at their homes, it can be done through the on or off button provided in the mobile application. A user’s on or off instruction is set within the database. The hardware receives this instruction and performs the desired action.

BACKGROUND Background: Lack of knowledge and poor attitude is one of the barriers to colorectal cancer screening participation. Printed material such as pamphlets and posters were the main approach in health education on disease prevention. Current information technology advancement had seen an increasing trend of the public to read from websites and mobile app using their smartphone. Thus, health information dissemination should also be diverted to the current trend of information search. Increase in knowledge and awareness will hopefully increase the screening participation and prevent late detection of diseases such as colorectal cancer. OBJECTIVE This study aimed to assess the effectiveness of ColorApp mobile applications in improving the knowledge and attitude on colorectal cancer among user aged 50 years old and above who are the population at risk for the disease in Kedah. METHODS Methods: A quasi-experimental study has been conducted involving 100 participants in Kedah, Malaysia. Participants from five randomly selected community empowerment program in Kota Setar district was chosen as the intervention group while Kuala Muda district was chosen as the control group. Participants were given a self-administered validated questionnaire on knowledge and attitude towards colorectal cancer. A usable mobile application, the ColorApp (Colorectal Cancer Application) was developed as a new educational tool on colorectal cancer prevention. The intervention group were given 2 weeks to use the ColorApp. The same questionnaire was redistributed to both groups after two weeks. The mean percentage score for knowledge and attitude between groups were compared using Repeated Measure ANCOVA. RESULTS Result: There was no significant difference of age, sex, highest education level, current occupation, and diabetic status between the two groups. The number of smokers was significantly higher in intervention groups as compared to control group and it has been controlled during analysis. There was a significant difference in mean knowledge score between intervention and control group with regards to time [Huynh Feldt: F (1,95) = 19.81; p < 0.001]. However, there was no significant difference in mean attitude score between intervention and control group with regards to time [F (1,95) = 0.36, p = 0.550]. CONCLUSIONS Conclusion: The mobile application can be one of the adjunct approaches in educating the public on colorectal cancer.
