    The use of motion sensors in measuring heart rate using smartwatch applications is currently a trend. Everyone is very helpful for measuring their own heart rate. This research is about the comparison of accuracy in motion sensors and measuring heart rate using the Analytical Hierarchy Process (AHP) method. Every technology and application in motion sensor measurement in heart rate measurement has almost the same features and uses as Xiaomi, Samsung, and Apple Inc. From the calculations carried out by the researcher, it shows that the field/stadium that is the most chosen by the community (respondents) is by Random Sampling, with the acquisition of a value of 0.490 aka 49.00%. The second is Treadmill with a value of 0.294 aka 29.40%. the overall value is 0.216 aka 21.60% The alternative that is most chosen by the community (respondents) is the field/stadium. The Analytical Hierarchy Process method can make it easier for prospective technology users to be able to measure the accuracy of motion sensors and detect heart rates, the AHP method makes product decisions based on criteria and alternatives contained in the hierarchy, the results of the study are Apple Inc. as the respondent's choice for technology that is trusted to measure better accuracy on the motion sensor and measure heart rate

    Analisis Kebutuhan Ruang Parkir Paragon Mall Semarang

    Paragon Mall Semarang is the one of the biggest shopping centers in Semarang City. Parking space has been provided since the beginning of mall's area development, however it is no longer sufficient to meet the current demand. It is proved by the additional parking area in certain times, thus the effectivity of this parking area needs to be assessed more thoroughly. This Study aims to plan the parking space's availability with sufficient capacity and to give recommendation in implemetation and development of parking space. Methodologies used include: calculation standart capacity based on current guidance, deviation of cumulative graph for calculating current need, space and tariff optimation, and future need calculation. Paragon Mall has 7 dedicated parking areas: 5 car parking areas and 2 motorcycle parking areas. At its peak hours, every area suffered space deficiency although there are some empty space in another parking area. Current parking space deficiency total of car area are only 10 SRPs and no deficiency in sepeda motor area. After optimation is done then the capacity is increased to 1115 SRPs of car and 2030 SRPs of sepeda motorcycle that is sufficient in the next 7 years or until year 2022. Tariff optimation is done to get progressive tariff therfore the visitors would not linger and eventually the space might serve more visitors. Space optimation on parking area layout and tariff should also be supported by management system. The overall amount of current parking space's availibility shortage is 10 SRPs of car. After performing space and tariff optimization, the capacity is 1115 SRPs of car and 2030 SRPs of sepeda motorcycle that will last for the next 2 years i.e. up to 2017.Parking area's layout of Paragon Mall Semarang with space and tariff optimization should also be supported by existing parking management system. Overall, Paragon's parking area is only experiencing a minimum shortage.. To overcome the possibility of uneven accumulation in particular parking, solution that can be given is installing information panel which shows available parking space of all parking lot at the entrance to Paragon Mall Semarang

    Acute alcohol produces ataxia and cognitive impairments in aged animals : a comparison between young adults and aged rats.

    Aging in both humans and rodents appears to be accompanied by physiological changes that increase biological sensitivity to ethanol intoxication; however, animal models designed to investigate the behavioral significance of increased alcohol sensitivity have yet to be established. The present study sought to determine if acute ethanol administration produces differential effects on motor coordination and spatial performance in adult and aged rats. Findings revealed a dramatic increase in ethanol induced ataxia and cognitive impairment in aged animals relative to young adults as evaluated by several behavioral tasks. Importantly, the heightened deficits seen in aged animals were not due to differential blood ethanol levels. Possible neurophysiological mechanisms are proposed to explain the age-related increase in sensitivity to motor- and cognitive-impairing effects of ethanol. Given the high prevalence of alcohol use among the elderly, increased vulnerability to alcohol-induced deficits may have a profound effect on injury and quality of life in this population.M.A

    Age-related differences in ethanol withdrawal, withdrawal-induced anxiety, cognition, and response to allopregnanolone.

    Research with humans and rodents suggests that symptoms of alcohol withdrawal may be more severe in the elderly compared with younger adults. However, investigations of the effects of repeated ethanol intoxications and withdrawals on persistent deficits in motor and cognitive performance in aged rats are limited. The present study thus sought to investigate age-related differences in the severity of ethanol withdrawal in adult and aged rats and examine potential long-term deficits resulting from chronic liquid ethanol diet. Results revealed that adult rats exhibited robust signs of ethanol withdrawal using a four-item behavioral scale (rigidity, hypoactivity, irritability, and intentional tremors) but showed only a non-significant trend of anxiety-like behavior and hyperactivity in the elevated plus maze and open field tasks during withdrawal. In contrast, aged animals consumed significantly less ethanol per body weight than adults and achieved minimal withdrawal scores using the standardized scale, but exhibited profound anxiety-like behavior during withdrawal. After a 14 day cessation from ethanol, adult and aged rats treated with chronic ethanol diet showed spatial learning deficits in water maze acquisition and a cognitively-challenging reversal paradigm. Chronic ethanol consumption did not result in significant motor impairments in either age group as assessed by the aerial righting reflex. When challenged with an acute dose of ethanol, adult and aged animals demonstrated metabolic but not cognitive tolerance to ethanol. Finally, we investigated the effects of an acute dose of allopregnanolone on spatial memory in aged rats. In accordance with previous research, adult animals showed impaired performance when treated with allopregnanolone. However, the results for the aged animals were not statistically significant. Interestingly, animals receiving an acute ethanol challenge showed greater allopregnanolone-induced impairments in the water maze compared to those receiving saline. The current study thus demonstrates that aged rats are especially vulnerable to anxiety-like behavior during ethanol withdrawal, and that repeated ethanol intoxications and withdrawals impair cognition in both age groups. Research targeting mechanisms and treatment of withdrawal-induced anxiety in the elderly is a promising avenue of future investigation
