The communication protocols used in industrial wireless networks are designed to meet requirements of security and reliability in communications. These requirements are guaranteed by techniques like message enciphering and radio frequency interference avoidance. The WirelessHART protocol was the first one developed specifically to meet the needs of industrial applications. WirelessHART networks use centralized control where one element, the network manager, is responsible for configuring, creating and maintaining the network. This feature increases reliability as management conflicts will not occur, but the rout of communications between network manager and field devices may need several hops on the network due to the mesh topology employed in the protocol. Procedures such as joining new devices require the exchange of a series of commands with the network manager, which takes a large period of time to be executed. This paper presents a technique designed for mobile devices aiming the reduction of time needed for the publishing service. The proposed technique favors the use of mobile devices with strict time constraints under the range covered by the wireless network and precedes the study of an efficient handover process. The results present a time comparison between the standard and proposed data collection.

The development experienced by humans when explored deeply will make people more confident in the power of God. Simple things such as the process of developing the language and art of children, in fact there is something extraordinary in it, which if disturbed will have an impact on further developments or other aspects.Writing this journal uses a qualitative approach, through observation, interviews, and documentation as a data collection technique. Based on the results of the research conducted, there are some results, namely the indicator of language development of VA class children basically has been achieved in accordance with the task of development at his age. But there are some things that have not been maximized in achieving this, such as the use of synonyms from several words, and metaphorical sentences that do not fully understand. The development of VA class art is in the phase of the Early Realism and the Early Age of Pseudo Naturalism which in the early realism phase In the period of Early Realism, children's work more closely resembled reality. Perspective awareness begins to emerge, but based on one's own vision. Keywords: Language Development, Art, Madrasah

Abstract Background Passive sensor data from mobile devices can shed light on daily activities, social behavior, and maternal-child interactions to improve maternal and child health services including mental healthcare. We assessed feasibility and acceptability of the Sensing Technologies for Maternal Depression Treatment in Low Resource Settings (StandStrong) platform. The StandStrong passive data collection platform was piloted with adolescent and young mothers, including mothers experiencing postpartum depression, in Nepal. Methods Mothers (15–25 years old) with infants (< 12 months old) were recruited in person from vaccination clinics in rural Nepal. They were provided with an Android smartphone and a Bluetooth beacon to collect data in four domains: the mother’s location using the Global Positioning System (GPS), physical activity using the phone’s accelerometer, auditory environment using episodic audio recording on the phone, and mother-infant proximity measured with the Bluetooth beacon attached to the infant’s clothing. Feasibility and acceptability were evaluated based on the amount of passive sensing data collected compared to the total amount that could be collected in a 2-week period. Endline qualitative interviews were conducted to understand mothers’ experiences and perceptions of passive data collection. Results Of the 782 women approached, 320 met eligibility criteria and 38 mothers (11 depressed, 27 non-depressed) were enrolled. 38 mothers (11 depressed, 27 non-depressed) were enrolled. Across all participants, 5,579 of the hour-long data collection windows had at least one audio recording [mean (M) = 57.4% of the total possible hour-long recording windows per participant; median (Mdn) = 62.6%], 5,001 activity readings (M = 50.6%; Mdn = 63.2%), 4,168 proximity readings (M = 41.1%; Mdn = 47.6%), and 3,482 GPS readings (M = 35.4%; Mdn = 39.2%). Feasibility challenges were phone battery charging, data usage exceeding prepaid limits, and burden of carrying mobile phones. Acceptability challenges were privacy concerns and lack of family involvement. Overall, families’ understanding of passive sensing and families’ awareness of potential benefits to mothers and infants were the major modifiable factors increasing acceptability and reducing gaps in data collection. Conclusion Per sensor type, approximately half of the hour-long collection windows had at least one reading. Feasibility challenges for passive sensing on mobile devices can be addressed by providing alternative phone charging options, reverse billing for the app, and replacing mobile phones with smartwatches. Enhancing acceptability will require greater family involvement and improved communication regarding benefits of passive sensing for psychological interventions and other health services.
