Published: April 2019

Background
Mobile health (mHealth) apps demonstrate promise for improving sleep at scale. End-user engagement is a prerequisite for sustained use and effectiveness.

Objective
We assessed the needs and preferences of those with poor sleep and insomnia to inform the development of an engaging sleep app.

Methods
We triangulated results from qualitative (focus groups and app reviews) and quantitative (online survey) approaches. A total of 2 focus groups were conducted (N=9). An online survey tested themes identified from the focus groups against a larger population (N=167). In addition, we analyzed 434 user reviews of 6 mobile apps available on app stores.

Results
Common focus group themes included the need to account for diverse sleep phenotypes with an adaptive and tailored program, key app features (alarms and sleep diaries), the complex yet condescending nature of existing resources, providing rationale for information requested, and cost as a motivator. Most survey participants (156/167, 93%) would try an evidence-based sleep app. The most important app features reported were sleep diaries (148/167, 88%), sharing sleep data with a doctor (116/167, 70%), and lifestyle tracking (107/167, 64%). App reviews highlighted the alarm as the most salient app feature (43/122, 35%) and data synchronization with a wearable device (WD) as the most commonly mentioned functionality (40/135, 30%).

Conclusions
This co-design process involving end users through 3 methods consistently highlighted sleep tracking (through a diary and WD), alarms, and personalization as vital for engagement, although their implementation was commonly criticized in review. Engagement is negatively affected by poorly designed features, bugs, and didactic information which must be addressed. Other needs depend upon the type of user, for example, those with severe insomnia.

Published: April 2019

Beban gesek pada permukaan sebuah benda dapat menimbulkan panas pada permukaan kontak benda tersebut. Semakin besar beban gesek yang terjadi, suhu pada permukaan material akan menjadi lebih tinggi. Peningkatan suhu permukaan yang semakin tinggi dapat mempengaruhi sifat mekanis permukaan material dan tentunya dapat berimplikasi terhadap mekanisme kegagalan pada permukaan material tersebut, seperti kegagalan aus dan kegagalan retak. Pada penelitian ini, uji kekerasan dilakukan pada material dengan suhu permukaan tertentu. Permukaan material baja karbon sedang dipanaskan dengan variasi suhu yaitu mulai dari suhu kamar sampai dengan 300ºC, kemudian dilakukan uji Vicker’s. Tingkat kekerasan dan profil indentasi Vickers pada permukaan material dengan variasi suhu tersebut kemudian diinvestigasi.
Friction load on the surface of an object can cause heat on the contact surface of the object. The larger the frictional load occurs, the temperature on the surface of the material will become higher. Increased surface temperatures can further affect the mechanical properties of the material surface and can certainly have implications for the failure mechanisms on the surface of the material, such as wear failure and crack failure. In this study, hardness tests were performed on materials with certain surface temperature. The surface of the carbon steel material is being heated with temperature variations ranging from room temperature up to 300ºC, then Vicker's test. The degree of hardness and Vickers indent profile on the surface of the material with the temperature variation is then investigated.
