Do College Students At Majmaah University Meet the Weekly Recommended Physical Activity Guidelines? Cross-Sectional Analyses

Background and Aims: Regular engagement in physical activity (PA) has been known to associate with improved health and quality of life measures. Prior research reported that only 46% of Saudi college students meet the weekly recommended PA volumes. However, these prior studies lack using standardized PA assessment methods, and therefore, this study examined PA levels and calculated the proportions meeting the weekly PA guidelines among college students currently enrolled in Majmaah university, Saudi Arabia. Methods: Currently enrolled college students at Majmaah university were included. PA levels was evaluated using the International Physical Activity Questionnaire-Short Form. This questionnaire contains 7-item questions regarding the weekly time spent in vigorous-to-moderate PA (MVPA), walking, and sitting behavior. Additionally, proportions meeting the weekly recommended PA was calculated. Results: One hundred and fifty-eight college students were enrolled (41.2% males, M age= 23.32 ± 4.5 years, and M body mass index (BMI)= 24.1±5.0 kg/m²). Male college students spent more time in MVPA (p=0.001, d=0.50) and met the weekly recommended PA cutoffs at a higher proportion compared to female college students (p=0.023). There were no other significant differences in PA levels between male and female college students (all p values >0.05). Conclusions: Male college students spent more time in higher activity intensity and met the weekly recommended activity cutoffs at a higher proportion than female students at Majmaah University. Future research should examine factors associated with increased activity levels such as socioeconomic status and/or physical or mental status among college students.

Effect of multiple chronic conditions on family doctor contracting in the elderly in China: the moderating role of socioeconomic status

BackgroundChina's family doctor contracting service is an important part of deepening the reform of the healthcare systems, aiming to further develop chronic disease management services, enhance the capacity of primary health care services and improve the health of residents. The purpose of this study was to explore the influence of multiple chronic conditions in the elderly on family doctor contracting and whether socioeconomic status played a moderating role.MethodsA cross-sectional survey was conducted in Beijing, China. A total of 1814 elderly people over 60 years old were included in this study using a whole-group sampling method. The univariate analysis and logistic regression analysis was used to analyze the data.Results21.72% of the elderly signed up with family doctors. The multiple chronic conditions was a factor influencing the elderly to sign up with family doctors (OR = 1.44, 95%CI = 1.28–1.61), and the higher the degree of multiple chronic conditions, the stronger willingness to sign up. Socioeconomic status positively moderates the effect of multiple chronic conditions on signing. Also, physical activity intensity (OR = 1.25, 95%CI = 1.03–1.54) and willingness to first visit primary care facilities (OR = 1.38, 95%CI = 1.25–1.54) influenced the elderly to sign up with family doctors.ConclusionsThe elderly with a high degree of multiple chronic conditions, high activity intensity, and a strong willingness to first visit primary care facilities were more likely to sign up with family doctors. The health literacy of the elderly should be further improved, and publicity on the family doctor contracting service policies for the elderly with lower socioeconomic status should be strengthened to guide them to sign up with family doctors. At the same time, the service capacity of primary care facilities should be further improved to meet the health needs of the elderly.

Debris flow susceptibility based on the connectivity of potential material sources in the Dadu River Basin

The Dadu River Basin (DRB) is an important economic corridor on the Chuanxi Plateau. The DRB is located in the highly changeable terrain of the eastern Qinghai-Tibet Plateau and is often threatened by debris flows. To mitigate the damage of debris flow disasters to the construction and operation of large infrastructures such as railways, roads and hydropower stations in the DRB, it is necessary to evaluate debris flow susceptibility. The connectivity of potential material sources (CPMS), which proxies the possibility of potential material transfer from the source to the outlet, was calculated using an improved index of connectivity, excess topography and brittle fracture index to identify and quantify debris flow susceptibility. The results show that the IC and the gully scale have a Logartihmic function in the DRB, in which IC decreases as the catchment area increases. In 3967 gullies of the Dadu River and its tributaries, the total connectivity of potential material sources (TCPMS) could be used to distinguish between debris flow gullies and non-debris flow gullies (AUC = 0.748). The TCPMS and average connectivity of potential material sources (ACPMS) were used to classify the scale and activity intensity of the 2398 debris flow gullies into four levels. The moderate- and high-activity intensity and large- and extra large-scale debris flows are mainly distributed in Danba, Luding and Kangding. The results of this study provide reference and evidence for the identification and evaluation of debris flow susceptibility.

Impact of Land Use and Transport Interaction on Transmition of COVID-19 in Jakarta

Land use and transportation are well known to interact and influence one another. The COVID-19 pandemic is the global health crisis. The world faces difficulties managing disasters while making efforts to slowing the spread of COVID-19. The COVID-19 pandemic spreads quickly through physical contact, making it easy to spread in public places. The purpose of this study to determine the effects of land use and transportation interactions on COVID-19 transmission. The quantitative descriptive analysis and spatial statistical methods in Geographic Information Systems (GIS) have been used in this study. Descriptive analysis to describe data related to land use characteristics in the research area. Spatial Statistical Method in GIS to analyze data from both structured and spatial observations. Cross-checking the land use from Google Street View around the bus stop within a 400 meter radius with the existing land use directly yielded the observations. The findings revealed that the type of land use demonstrated an intensity of activity that had a high potential for spreading COVID-19 because at the bus stop with land use around the trading center, shopping centers, and office buildings that have a high activity intensity, it appears that they have a high positive number of COVID-19

Characteristics, formation mechanism and evolution model of Ordovician carbonate fault-controlled reservoirs in the Shunnan area of the Shuntuogole lower uplift, Tarim Basin, China

The Ordovician carbonate fault-controlled reservoir in the Shunnan area is substantially different from the typical karst reservoir closely related to an unconformity. The development of fault-controlled reservoirs is controlled by the deep and large strike-slip fault in the Middle Caledonian period. The characteristics, diagenesis types, diagenetic fluid evolution characteristics, fluid-rock interactions, and reservoir response of fault-controlled reservoirs were investigated systematically by analyzing 3D seismic, logging, and drilling core data. Production data, reservoir petrology, and chemical filling geochemistry were also used. The formation and evolution of fault-controlled reservoirs are affected by the coupling of the structure, lithofacies, and fluid. The dolomitization in the quasi-syngenetic period in the early stage of Episode I in the Middle Caledonian provided the material basis for the development of fault-controlled reservoirs. The Mg-rich high-salinity thermal fluid in the late Caledonian and the Early Hercynian provided a constructive transformation for the development of fault-controlled reservoirs. In contrast, the transformation of reservoirs by the Si-rich magmatic thermal fluid in the late Hercynian was mainly destructive, and the action range of the deep thermal fluid was strongly controlled by strike-slip fault zones. The releasing bend and superimposed parts of different structural styles in the fault zone have high activity intensity. These are areas where dissolution and transformation of the fluid occur preferentially. Dolomite is often more conducive to the development of fault fracture zones and promotes the dissolution and transformation of the deep thermal fluid. Therefore, the strike-slip fault cutting through the basement causes the hydrothermal fluid to enter the fault, dissolving carbonate minerals and forming a hydrothermal-modified fault-controlled reservoir composed of fractures, dissolution pores, and dolomite intercrystalline pores. The results provide a new approach and direction for the study of different types of deep and ultra-deep carbonate reservoirs.

Developmental pathways linking the quality and intensity of organized afterschool activities in middle school to academic performance in high school

IntroductionAdolescents' organized afterschool activities have been linked to their academic performance, but processes contributing to these relations are not well understood. This study tested two pathways linking activity intensity and activity quality in 6th grade to high school academic performance: adolescents' activities in 9th grade and adolescents’ academic skills in 9th grade. MethodsData were from the Study of Early Child Care and Youth Development, a longitudinal study conducted at 10 sites in the United States. Data were collected from 918 participants (51% female) who were assessed in 6th grade (Age 12; middle school), 9th grade (Age 15; beginning of high school), and 12th grade (Age 18; end of high school). Results & ConclusionsFindings from structural equation models indicated that adolescents who had higher activity intensity and activity quality in 6th grade participated in activities with higher intensity and quality in 9th grade. These 9th grade activities formed an indirect path linking 6th grade activities to high school academic performance, including grades and number of advanced classes. In addition, 6th grade activity quality promoted adolescents’ work orientations in 9th grade, a key academic disposition that then predicted grades and number of advanced classes in high school. These findings suggest that organized afterschool activities in middle school may prepare adolescents for academic success in high school via their participation in activities in 9th grade as well a stronger work orientation in 9th grade.

SEBARAN LUTUNG Trachypithecus cristatus (Raffles, 1821) DI PULAU PAHAWANG, INDONESIA

Human and wildlife conflicts have a negative impact, especially langurs whose habitat in a small island. The study objective was to identify presence and the distribution of langurs in a small island. Data were collected using observation methods, then analyzed using descriptive analysis. The results show that there were 23 langur groups that distributed in 23 locations, with the number of smallest groups consisting of 6 individuals and the number of largest groups consisting of 12 individuals. Langur was found in the morning at 05.38 WIB-10.57 WIB and in the afternoon at 17.08 WIB-18.10 WIB. Most of these animals are found in agroforestry areas and a small part in mangrove forests. The highest activity intensity is found in the morning with the form of eating, locomotion (moving), grooming and resting activities. The existence of langurs in a small island is a good thing and must be preserved because langurs belong to protected animals. One way to conserve these animals is to create alternative conservation-based langur tourism.

Petroleum charge and entrapment along active faults: Study of the accumulation mechanism of the Qinhuangdao 29 oil field on the slope of the Shijiutuo uplift, Bohai Sea

In the Qinhuangdao 29 (QHD29) oil field, oil generated from the first member of the Shahejie source rocks is mainly contained in Paleogene reservoirs, whereas deeper oil sourced from the third member of the Shahejie (Es3) source rocks is generally accumulated in Neogene reservoirs. The present study was undertaken to better understand the differences in petroleum accumulation in the QHD29 oil field and to provide suggestions for future petroleum exploration on the Shijiutuo uplift. Laser Raman spectroscopy reveals that carbon dioxide (CO2) exists with hydrocarbon gas in the same fluid inclusions. Measured homogenization temperatures of aqueous inclusions range from 80°C to 160°C (176°F to 320°F), indicating late-stage rapid petroleum accumulation with a charging time of no earlier than 5.1 Ma. The results of grains containing oil inclusions measurements reveal the presence of paleo-oil accumulation in the current natural gas column. In terms of the boundary fault activity rate (FAR), CO2 distribution is quite relevant to the late-stage activity of boundary faults, with high content of CO2 corresponding to the section of the F1 fault with high-intensity activity (higher FAR values). Both Neogene and Paleogene reservoirs in well A1 contained predominantly Es3-derived oil and were accompanied by abundant mantle CO2. This reveals the segmented vertical transport of petroleum in the fault: both the mantle-derived CO2 and hydrocarbons vertically migrated and accumulated in shallower reservoirs in the high-activity intensity section of the boundary fault. This may account for the occurrence of predominantly Es3-derived oil in the reservoirs near the section of the fault with high activity intensity. In the eastern part of the QHD29 oil field, vertical migration may have been limited because of the relatively low intensity of fault activity, and the distribution of sandstones seems to dominate the petroleum accumulation. Our research reveals that lithologic traps in the Es3 stratum may still have great potential for exploration along the slope of the Shijiutuo uplift.
