FATIGUE AND PHYSICAL HOUSEHOLD ACTIVITY IN PEOPLE LIVING WITH HIV

Резюме. Цілі: дослідити зв'язок втоми у людей що живуть з ВІЛ (ЛЖВ), побутової фізичної активності та факторами, які можуть на неї впливати. Матеріали і методи: Обстежено 60 ЛЖВ, 40 чоловіків і 20 жінок у віці від 23 до 61 року. Втому оцінювали за допомогою шкали FAS. Фізичну активність вивчали за допомогою щоденника фізичної активності, якість життя (ЯЖ) – опитувальником SF 36. Показник рівня CD4+ T-лімфоцитів визначали методом проточної цитофлуориметрії, вірусне навантаження (ВН) - за допомогою ПЛР. Результати дослідження та їх аналіз. Ступінь втоми у ЛЖВ коливалася від 17 до 47 балів, середнє значення – 36,4 ± 6,4 балів. До першої групи увійшло 46 пацієнтів з вираженою втомою, а до другої – 14 пацієнтів з помірною. У I групі встановлено: пряму кореляцію з вірусним навантаженням (r = 0,16, р = 0,02), позитивну кореляцію між психічним компонентом ЯЖ та тривалістю сну (r = 0,24, р = 0,06); зворотній зв'язок з фізичною побутовою активністю (r = -0,43, р = 0,0001), загальним показником ЯЖ (r = -0,16, p = 0,02), фізичним та психічним компонентами ЯЖ – r = -0,19, р = 0,03 та r = -0,37, р = 0,13 відповідно, рівнем CD4+ T-лімфоцитами та ВН (r = -0,25, р = 0,06). У II групі встановлено: пряму кореляцію між втомою та тривалістю сну r = 0.46, р = 0.22, ВН r = 0.24, р = 0.28; зворотна кореляція була між ступенем втоми та загальним показником ЯЖ r = -0.18, р = 0.03, фізичним компонентом ЯЖ r = -0.15, р = 0.02., рівнем CD4+ Т-лімфоцитів r = -0.27, р = 0.17, фізичною побутовою активністю r = -0.35, р = 0.005, ВН r = 0.53, р = 0.28. Висновки. Побутова фізична активність може зменшити втому у ЛЖВ. Тривалість сну позитивно впливає на досліджувані нами патерни здоров’я у ЛЖВ. Встановлено, що втома пов’язана з високим ВН, низькою ЯЖ та ІМТ. Виникає потреба у розробці математичної моделі оцінки втоми.

The increasing use of electrical energy in society in 2020 is closely related to the pandemic problem that is occurring. Increased household activity causes a surge in energy in the household sector. This increase in energy consumption needs to be balanced by providing exposure to the utilization of existing electrical equipment in households. The lighting system give an important role in energy consumption in the household sector. The dedication carried out is by providing knowledge on the use of the lighting system, the rules in PUIL 2000 and the calculation of the Basic Electricity Tariff (TDL) in 2020. Submission of this will certainly increase public understanding of energy savings so that it can contribute to overcoming the problem of electricity devisit occur.

Activity Recognition in Residential Spaces with Internet of Things Devices and Thermal Imaging

In this paper, we design algorithms for indoor activity recognition and 3D thermal model generation using thermal images, RGB images, captured from external sensors, and the internet of things setup. Indoor activity recognition deals with two sub-problems: Human activity and household activity recognition. Household activity recognition includes the recognition of electrical appliances and their heat radiation with the help of thermal images. A FLIR ONE PRO camera is used to capture RGB-thermal image pairs for a scene. Duration and pattern of activities are also determined using an iterative algorithm, to explore kitchen safety situations. For more accurate monitoring of hazardous events such as stove gas leakage, a 3D reconstruction approach is proposed to determine the temperature of all points in the 3D space of a scene. The 3D thermal model is obtained using the stereo RGB and thermal images for a particular scene. Accurate results are observed for activity detection, and a significant improvement in the temperature estimation is recorded in the 3D thermal model compared to the 2D thermal image. Results from this research can find applications in home automation, heat automation in smart homes, and energy management in residential spaces.

Equilibrium of Invisible Hand in the Family: the Gravitation between Men and Women in Marriage Markets

The proof of the Invisible hand describes the inner market mechanism, which leads the producer to the meeting point with the uninformed consumer, where the price and the meeting time provide the maximization of the output on the consumption-leisure production possibility frontier and unintentionally maximize the buyer’s consumption-leisure utility. This mechanism also works in marriage markets where the Invisible hand corrects the misleading information. The paper confirms G. S. Becker’s assumption that more beautiful, charming, and talented women tend to marry wealthier and more successful men but refutes his conclusion that such marriage maximizes the aggregate output. The high male productivity really attracts women because it produces a strong male gravitation field. But the marriage of a very productive man to a beautiful woman fails because it represents for a beautiful woman a corner solution. The man’s wealth, accumulated before the marriage, as well the bride price reinforces this disequilibrium. A dowry can also result in a disequilibrium because it gives time for a man to look for another partner. The paper argues that the quality of men is determined not by their productivity as such but by the trade-off between the productivity and their ability to provide household services on the family consumption-leisure production possibility frontier. The quality of women is determined by the trade-off between household activity and efforts to support her natural female attractiveness. The invisible hand equilibrium represents something close to the mating of unlikes but with some peculiarities. The woman’s ability to provide household services substitutes the man’s household activity but it complements his gender-related quality of productivity. A housewife raises the productivity of her husband; she increases his attractiveness and reinforces his gravitation field at the expense of her own attractiveness and her gravitation field but only this way she maximizes her consumption-leisure utility. Polygamy also represents the invisible hand equilibrium but in this case the equal distribution of wealth between wives is followed by unequal distribution of household activities when some wives spend less time in the kitchen but more leisure time with the husband because they are more attractive. In monogamy, the woman’s strong gravitation field produces the phenomenon of the ‘tragedy of a femme fatale’. Her alliance with a wealthy man comes to the corner solution; she needs more attention of her husband but with that she decreases his gravitational field, and he becomes less interesting to her. The loss of male attractiveness results in the short time horizon of the equilibrium determined by the invisible hand.

Dual Effects of Hearing Loss and Dementia on Functional Limitations in Older Adults

Age-related hearing loss (HL) is both common and associated with elevated risk for cognitive decline and poorer health. To care for an aging population, it is critical to understand the effect of coexisting HL and dementia on functional activities. The effect of co-existing dementia and self-reported HL on daily functioning were assessed. A cross-sectional analysis was performed using nationally-representative data from the 2015 National Health and Aging Trends Study consisting of U.S. adults 65+. The sample included 1,829 adults with HL (22.8%) and 5,338 adults without HL. Multivariable Poisson regression was used to model the independent effects and interaction of self-reported HL and dementia status on three validated functional activity scales (self-care, mobility, and household). All analyses adjusted for sociodemographic and medical factors. HL participants were more likely to be white, older, male, less educated (p <0.01). 8.4% had possible dementia and 6.5% had probable dementia. Respondents with HL or possible or probable dementia had significantly lower mobility, self-care, and household activity scores (p<.001 for all comparisons) compared to their peers. A small yet significant interaction was present in all models, suggesting that HL respondents with co-occurring dementia had lower mobility, self-care, and household activity scores than predicted by the independent effects of dementia and self-reported HL (p<.001 for all comparisons). Older adults with co-occurring dementia and HL are at increased risk for poor functioning and should be screened by healthcare providers. Future work should consider the impact of intervention in this vulnerable/at-risk population.

Diurnal Profiles of Locomotive and Household Activities Using an Accelerometer in Community-Dwelling Older Adults with Musculoskeletal Disorders: A Cross-Sectional Survey

The present study investigates the diurnal profiles of locomotive and household activities in older adults with musculoskeletal disorders (MSDs) using an accelerometer. Furthermore, we examined the effect of chronic pain on their diurnal profiles in both activities. Seventy-one older adults with MSDs (73–89 years) were included in this cross-sectional survey, and 25 age-matched older adults (75–86 years) were selected as healthy older adults. The daily physical activities, including steps walked and locomotive and household activity intensities, were recorded using a triaxial accelerometer in terms of metabolic equivalent task-hours per week (MET-h/week). The diurnal profiles of steps and locomotive activities in older adults with MSDs were considerably lower than those of healthy older adults. In contrast, there was no significant decline in household activity. However, the locomotive and household activities were reduced by severe chronic pain. This survey demonstrated that the diurnal profiles of household activity in older people with MSDs as well as those in age-matched healthy older adults were maintained. Furthermore, severe chronic pain influenced both activities. Therefore, the maintenance of household activity throughout the day, as well as the management of chronic pain, may be important strategies for the promotion of physical activity in older people with MSDs.
