Development and catch efficiency of an attracting device to collect and monitor the invasive fireworm Hermodice carunculata in the Mediterranean Sea

The fireworm Hermodice carunculata (Annelida) is emerging as a native invader and a neonative species in the Central Mediterranean basins. Its ongoing areal expansion has probably been triggered and pursued by the climate alterations which are affecting the Mediterranean environments and biota. However, increased H. carunculata abundance and distribution may be miscalculated and underestimated due to the lack of effective tools for collection and monitoring. Indeed, fireworms spend most of the daytime in crevices and holes, making it impossible to obtain reliable data in underwater surveys.In this study, traps were developed to provide suitable shelter and food to fireworms, and their effectiveness and specificity were assessed by testing different immersion times, environmental conditions and types of bait. Pierced plastic baskets adapted for fireworm capture proved to be extremely easy to set up, reproducible, cheap, and highly specific. The devices were used in 11 sites located along the Ionian Apulian coast (Italy). They resulted suitable and effective: more than 90% of the traps baited with raw fish succeeded in capturing H. carunculata specimens, with an average of 8-9 fireworms captured per trap. The traps were deployed in a depth range of 1.5-9 m with immersion times of up to 4 h, and even large sized fireworms (> 32 cm in length) were caught. These attracting devices could be successful in different forthcoming challenges, allowing the collection of a great number of fireworms to investigate their impact on rocky bottom communities, distribution and potential for bioprospecting. Besides, the cheapness and ease of use of the traps also make them suitable for Citizen Science studies and sampling campaigns aiming at characterizing the expanding populations. Future applications will be critical to improve deployment success and test user friendliness.

AbstractAn e-commerce website which is a website for conducting buying and selling transactions must have an attractive User Interface (UI) in order to make many users interested in using their website in buying and selling transactions. The User Interface is one of the factors that determine the number of visitors to a website. User Interface is discussed in the discipline of HCI (Human and Computer Interaction) or also known as human and computer interaction. Because the User Interface is so important on a website, a Usability Test is needed, to check how efficient and effective the website's User Interface is. In this study, the authors compare the Usability Tests of two e-commerce websites, namely Bukalapak and Shopee, which are 2 of the 3 biggest e-commerce websites in Indonesia. The method used is the Heuristic method which all of its characteristics can be used to test all the characteristics of an efficient and effective User Interface. The research was conducted by distributing questionnaires to 70 correspondents. From the results of this study, it was found that the Shopee website was more effective and efficient to use compared to the Bukalapak website.

Soda Machine and User Experience: A Study of Icon Display

Touch-screen GUIs have become a key feature of modern consumer electronics. The purpose of this study is to investigate the effect that reducing the number of icons on the GUI of a popular soda machine has on drink selection time and user satisfaction. Twenty subjects participated in the study, with 10 assigned to the control and experimental groups respectively. Time to make a drink selection was recorded and compared between groups using unpaired t-test. User satisfaction was measured using a five-point scale questionnaire. The results suggested that user satisfaction, except for the display dependability category, is not affected by the reduction of the number of icons on the soda machine GUI and no change was observed in drink selection time.

Reminder and Online Booking Features at Android-Based Motorcycle Repair Shop Marketplace

Generally, vehicle service is a must for the vehicle owner. However, due to tight work routines, people often forget to service their vehicles. In addition, the service process is still using a manual system, such as taking a queue number which leads to the long queue of the service time. An Android-based Motorcycle Repair Shop Information System provides a solution to remind people to do a regular service on their vehicles with a reminder feature and make online bookings. The system development uses the SDLC (System Development Life Cycle) method. The implementation process requires an Android smartphone and a computer device by using MySQL as data storage, Firebase as a notification sender, React native and Visual Studio Code are used for developing the system. The results of the UAT test (user acceptance testing) from 20 users show 55,8% answered agree to the display, features and flow of the system, 39,5% answered strongly agree to the three question parameters, and 4,7% answered disagree with the flow and display of the system.

Empathic accuracy in design: Exploring design outcomes through empathic performance and physiology

Empathic design highlights the relevance of understanding users and their circumstances in order to obtain good design outcomes. However, theory-based quantitative methods, which can be used to test user understanding, are hard to find in the design science literature. Here, we introduce a validated method used in social psychological research – the empathic accuracy method – into design to explore how well two designers perform in a design task and whether the designers’ empathic accuracy performance and the physiological synchrony between the two designers and a group of users can predict the designers’ success in two design tasks. The designers could correctly identify approximately 50% of the users’ reported mental content. We did not find a significant correlation between the designers’ empathic accuracy and their (1) performance in design tasks and (2) physiological synchrony with users. Nevertheless, the empathic accuracy method is promising in its attempts to quantify the effect of empathy in design.
