Published: July 2021

As an effort to control and handle COVID-19, the government has issued a school from home (SFH) policy. This policy has forced children to stay at home and carry out learning using digital media. This situation has an impact on increasing the use of digital media and the involvement of parents in children's learning significantly. This study explores the use of digital media in children in Surabaya during the pandemic period and how parents can assist the use of these media. This research uses qualitative methods with in-depth interview techniques. Researchers distributed questionnaires about the use of digital media to 66 parents, and nine parents stated that they were willing to become informants. The results show that in addition to a significant increase in the time to use digital media during the pandemic, the pandemic has also changed the parental assistance and supervision of children. Before the pandemic, the assistance model was carried out more with technical restrictions, in the form of time restrictions, content access, application choices, and the number of data packages (restrictive mediation). However, during a pandemic, the mentoring model was carried out with active mediation through discussions and critical thinking, active together with devices, close surveillance, and monitoring on applications and post online activities (active mediation, co-using, supervision, monitoring). One of the pandemic's positive impacts is the opening of discussion spaces between parents and children, the opportunity to use gadgets together, and opportunities for children and parents to learn digital skills.

Published: July 2021

This research uses a qualitative approach to explore inter-Island mobility and social change in Tidore Island, North Maluku. Data obtained from observations and interviews show that social change in Tidore occurred due to the dynamic factors of cross-island population mobility in recent years. Data were divided into groups of those who are working semi-permanently and those who are commuting to work (commuters). The main factors triggering inter-island population interactions in Tidore City are the need for labor supply, basic commodities in the food and logistic sector, as well as support services from several groups. Conversely, this town is the center of government services with labor suppliers in the formal sector (government) and service economy. It also depends on certain commodities that can only be supplied from the surrounding Island (Halmahera). The research analysis shows that infrastructure (transportation) availability contributes to the intention of local government and the community to create new economic centers in the form of regional commodity markets and additional ports to support population mobility as active mediators for the sustainability of socio-economic development in this region.

Authors: Berg A. V. , Penina G. O.
Published: July 2021

The dominant position among the reasons of working-age population’s health deterioration belongs to diseases of the peripheral nervous system (PNS), the peak prevalence of which occurs at the age of 35–40. PNS diseases are diagnosed in about 76.0% of industrial workers, and account for more than half of all occupational diseases. They are the main cause of incapacitation and long-term disability. Publications on disability due to PNS diseases are isolated.

The aim of the work. Clinical and functional characteristics of PNS disorders that cause disability in the working-age population.

Material and methods. Among 91 496 first recognized as disabled in the Republic of Bashkortostan in 2014–2018, all disabled people of working age were selected due to PNS diseases, in which the main independent diagnosis was radiculopathy, polyneuropathy, neuropathy and vibratory disease with indication to lumbar-sacral radiculopathy with polyneuropathy of the upper extremities. 107 people were identified to constitute a closed cohort for a comprehensive study of the clinical-functional state and patterns of disability formation in them. The clinical-functional characteristic is given on the basis of the results of studies set forth in the directional medical documents and the assessment by an expert neurologist of the Main Bureau of Medical and Social Expertise. Statistical analysis was performed in Microsoft Excel.

Results. The prevalence of PNS diseases has been found to be increasing. Three of the newly diagnosed neurological patients have been the carriers of PNS disease. PNS diseases are formed and reach peak in working age. Characterized by a chronic, progressive course, they often cause temporary and persistent disability. On average, there are 0.1 ± 0.028 persons with disabilities per 10 thousand of the able-bodied population due to PNS diseases, the level of which in dynamics for 2014–2018 increased by 1.7 times. Persons with disabilities (69.0%) are mainly represented by men, every second (50.6%) is over 50 years old, with an average age of 48.7 ± 5.7 years. The clinical-functional state is characterized by constant pain, numbness, seizures, restriction of movements in the limbs, sensory disorders, vegetative-vascular disorders.

Conclusion. The quantitative evaluation of the main types of the body functions and main categories of vital activity persistent disorders made it possible to detect that 69.3 ± 4.4% persons with disabilities have persistent moderate abnormalities of functions in the range 40–60% (II degree), another 24.4 ± 3.8 — persistent pronounced abnormalities in the range 70–80% (III degree) and 6.3 ± 6.0% — persistent significant abnormalities in the range 90–100% (IV degree).

The term «hypertensic crisis» is used to describe a condition that develops over time, and the outcomes depend on both, timing and completeness of medical care and the initial clinical status of the patient. The term «uncontrollable arterial hypertension» in ESC and RSC recommendations (2018–2020) cannot replace the concept of “uncomplicated HC” completely . It is advisable to adhere to the recommendations of the Russian Medical Society for Arterial Hypertension (RMSAH) developed in 2019, in which the division into complicated and uncomplicated HC still remains. In clinical practice, three variants of a signifi cant increase in blood pressure in patients with arterial hypertension should be distinguished: an isolated increase in blood pressure, uncomplicated and complicated HC. It is necessary to stratify patients with uncomplicated HC according to the degree of risk of cardiovascular complications development in order to determine the indications for their hospitalization. The rapid relief of a significant increase in blood pressure should lead to a safe level of patient’s pressure, taking into account the risk of hypotension and hypoperfusion of vital organs and systems.

Considering there are no activities in an office during nights and holidays, makes the business owners feel uncomfortable leaving the office. To overcome this problem, a sensor is to monitor a situation in the office whether there is a gas leak or a hotspot. It is hope that air pollution and fire monitoring tool can help to prevent fires. The way this tool works uses the Arduino Uno to retrieve data from the gas sensor and flame sensor. The data will be sent to the Ubidots server via NodeMCU ESP8266 as wifi or the internet. The monitoring display can be seen via Android and when there is an emergency, the ubidots server will immediately notify the room owner. The result shows that the effective distance of the sensor is around 10cm to 50 cm and the overall system runs well
The Design of Accident Detection and Tracking Systems on Motorcycles
Authors: Ramadaniati Febi
Published: July 2021

Motorcycles are type of vehicles with the highest accidents percentage every year. The location away from the settlement and the time of the accident is one of the factors that slow down the spread of information about accidents. This study aims to make a tool that can send such information in the form of notifications and crash site points to the victims’ families. Testing was conducted by looking at the sensor response detecting tilt on the motorcycle against the large reading angle. Furthermore, GPS module accuracy testing is conducted in reading the location by comparing GPS module readings with actual location points in Google apps Maps which is then calculated by using the Haversine Formula method up to gsm module capability testing for send SMS notifications in the form of latitude, longitude, and links that can connect to the Google Maps app. Based on the results of the trials and analyses that have been conducted, the slope sensor response area to transmit crash notification is <=50° or >=50°. After that, the GSM module will send notifications and location points detected by the GPS module with an average reading difference of 2.97 meters.
