Objectives: Optimal amount of muscle and fat mass has been associated with level of physical activity and are basic determinants of individuals’ health, fitness including occupational performance. The study determined the level of occupational physical activity and influence on anthropometrics, body composition and health of bricklayers in Kwara state, Nigeria. Methods: Descriptive correlational design was used. During the study only three bricklaying sites were functional and all the 45 bricklayers who met the inclusion criteria were purposively selected. Standardized instruments: non-elastic anthropometric tape rule, stadiometre and weight scale were used for anthropometric and body composition measurement while Occupational Physical Activity Questionnaire (OPAQ; r = .72) was used to assess work-related physical activity. Pilot test was conducted to confirm calibration and functionality of body composition equipment. Informed consent was sought from the participants with ethical approval obtained from the Institutional board. Statistical analysis was performed using SPSS V20.0 with descriptive statistics of mean and standard deviation for analyses of body composition and physical activity while inferential statistics of PPMC and t-test were for analysis of hypotheses at a 0.05 alpha level. Results: Participants performed vigorous intensity occupational physical activity expending an average of 2,699.1 MET-min∙wk-1. Occupational physical activity negatively correlated with their body mass index (N = 45, r = -.06, r2 = .36%, p = .05); Waist circumference (N = 45, r = -.083, r2 = .69%, p = .05) and positively correlated with their bicep circumference (N = 45, r = .61, r2 = 37.2%, p = .001) and chest circumference (N = 45, r = .40, r2 = 16%, p = .007). Conclusions: Bricklaying positively influenced body parameters which might induce health and fitness benefits. However, there is need for health promotion intervention for enlightenment and healthy lifestyle practice among bricklayers to improve overall health and fitness.

The red alga Gracilaria vermiculophylla, a species native to the waters of Korea and Japan, has invaded marine coastal areas of Europe and the Americas, thriving in conditions that differ from those of its native habitat. In recent years, G. vermiculophylla has been discovered in the Long Island Sound (LIS) estuary growing alongside the native congener Gracilaria tikvahiae. The goal of this study was to determine whether the two strains of G. vermiculophylla from different regions of the world have evolved genetic differences (i.e., ecotypic differentiation) or if the physiological performance of the strains simply reflects phenotypic plasticity. Two strains of G. vermiculophylla (isolated in Korea and LIS) and a strain of the LIS native G. tikvahiae were grown for four weeks under temperatures ranging from 20 to 34°C using a temperature gradient table (all other environmental conditions were kept constant). At the end of each week, wet weight of each sample was recorded, and thalli were reduced to the original stocking density of 1 g L−1 (excess biomass was preserved for tissue carbon and nitrogen analysis). Generally, the growth rates of Korean G. vermiculophylla > LIS G. vermiculophylla > G. tikvahiae. After one week of growth G. tikvahiae grew 9.1, 12.0, 9.4, and 0.2% d−1, at temperatures of 20, 24, 29, and 34°C, respectively, while G. vermiculophylla (LIS) grew 6.6, 6.2, 5.7, and 3.6% d−1. G. vermiculophylla (Korea) grew 15.4, 22.9, 23.2, and 10.1% d−1, much higher than the two strains currently inhabiting the LIS. On average, the LIS G. vermiculophylla strain contained 4–5% DW N, while the Korean strain and G. tikvahiae had more modest levels of 2–3% N DW. However, tissue N content declined as temperature increased in LIS and Korean G. vermiculophylla. The non-native haplotype may have evolved genetic differences resulting in lower growth capacity while concentrating significantly more nitrogen, giving the non-native a competitive advantage.

Clinical utilization of shear wave elastography in the musculoskeletal system
Leah C. Davis,Timothy G. Baumer,Michael J. Bey,Marnix van Holsbeeck 대한초음파의학회 2019 ULTRASONOGRAPHY Vol.38 No.1
Shear wave elastography (SWE) is an emerging technology that provides information about the inherent elasticity of tissues by producing an acoustic radiofrequency force impulse, sometimes called an "acoustic wind," which generates transversely-oriented shear waves that propagate through the surrounding tissue and provide biomechanical information about tissue quality. Although SWE has the potential to revolutionize bone and joint imaging, its clinical application has been hindered by technical and artifactual challenges. Many of the stumbling blocks encountered during musculoskeletal SWE imaging are readily recognizable and can be overcome, but progressive advances in technology and a better understanding of image acquisition are required before SWE can reliably be used in musculoskeletal imaging.
Chindia: Does Culture Matter in Hindu and Confucian Economies?
Leah Green,Patrick Mendis 연세대학교 동서문제연구원 2008 Global economic review Vol.37 No.4
China and India (Chindia) have begun in recent years to enjoy growing measures of economic success, reversing the centuries of structural poverty and their negligible rates of economic growth. This article examines the influence of varying cultural propensities-Hinduism in India and Confucianism in China--and their impact on each country`s economic turnaround. It discusses the historical circumstances that shaped Chindia`s perspectives on foreign direct investment and how the external forces contributed to their domestic policymaking. It also addresses three ways in which culture can affect economy and the two major events that cemented the direction of Chindian economic growth. Finally, the paper presents a comparative analysis of China and India and their respective impact of culture on development. It asserts that the forces of culture and its historical development do matter, especially when it comes for a nation to reverse its deprived and stagnated situation and to achieve a status of economic powerhouse.

<P><B>Abstract</B></P> <P>Dengue viruses (DENV1-4) are mosquito-borne flaviviruses estimated to cause up to ∼400 million infections and ∼100 million dengue cases each year. Factors that contribute to protection from and risk of dengue and severe dengue disease have been studied extensively but are still not fully understood. Results from Phase 3 vaccine efficacy trials have recently become available for one vaccine candidate, now licensed for use in several countries, and more Phase 2 and 3 studies of additional vaccine candidates are ongoing, making these issues all the more urgent and timely. At the “<I>Summit on Dengue Immune Correlates of Protection</I>”, held in Annecy, France, on March 8–9, 2016, dengue experts from diverse fields came together to discuss the current understanding of the immune response to and protection from DENV infection and disease, identify key unanswered questions, discuss data on immune correlates and plans for comparison of results across assays/consortia, and propose a research agenda for investigation of dengue immune correlates, all in the context of both natural infection studies and vaccine trials.</P>

Brucellosis is a notorious zoonotic disease with global implications. Efforts to control the spread of the disease have been restricted to the agricultural livestock. Increasing incidences of accidental human infection have motivated researches to start working on alternative vaccines. At present, live attenuated vaccines are the only accepted type of vaccines used in developed countries for the prevention of brucellosis. Although serodiagnosis is occasionally unreliable, some countries have already claimed to have eradicated the disease, based on this testing. Live attenuated vaccines are not suitable for use in pregnant and immune-depressed animals. Moreover, these vaccines are not tolerated in humans. Therefore, many researches have been striving to discover alternative methods of vaccination. Most research has focused on the generation of subcellular, subunit, and DNA vaccines that are as efficient as the live attenuated vaccines. At present, none of the available vaccines has been able to replace the live attenuated vaccines. Therefore, additional research is necessary in order to discover a new brucellosis vaccine that is suitable for human use.
Involvement of Social Media in Disaster Management during the Wenchuan and Ya'an Earthquakes
Li, Leah Xiufang Center for Asian Public Opinion ResearchCollaborat 2014 Asian journal for public opinion research Vol.1 No.4
Social media is being increasingly utilized in disaster relief work to identify safety issues, locate displaced-victims, and seek or provide support for those who need help. The presence of social media in disaster management has changed significantly in recent years, as it was not prevalent in the 2008 Wenchuan earthquake, but had become a powerful force in the 2013 Ya'an earthquake. This paper discusses the development of social media in disaster management via making a comparison between how it functioned in the two earthquakes. It examines the following aspects: who are the stakeholders that use social media in the earthquake management; how do they adopt this means in response to the earthquakes; and what are the outcomes of adopting social media with regards to public engagement and collaboration in an emergency event. As Sina Weibo acts as the equivalent of China's Twitter, the methodology relies on an analysis of posts in Weibo. The outcomes primarily show that: (1) authorities, celebrities and the public actively adopted social media for the purpose of information dissemination and resource mobilization; and (2) social media users are both content consumers and content generators in the times of earthquakes. The study concludes that social media as a backchannel communication tool is helpful for government institutions, corporations, and nonprofit organizations to build relationships with their stakeholders in the disaster management cycle. The result will interest academics and emergency management practitioners who are concerned with improving disaster communication.

Brucellosis affects a wide range of host species, including humans and many livestock animals. Chronic infections of the disease make antibiotic treatment costly, and the current vaccine used in livestock has not been approved for human use. This study investigated the possible use of the Brucella abortus outer membrane protein A (OmpA) as a candidate subunit vaccine in an infected mouse model. The ompA gene was cloned and overexpressed, and the recombinant OmpA (rOmpA) protein fused to maltose binding protein (MBP) was purified in Escherichia coli. Immunogenicity was verified through western blotting, and mice were immunized and challenged to evaluate its protective effect. Mice treated with rOmpA exhibited induced humoral and host cell-mediated responses, with a significant increase in immunoglobulin G (IgG1 and IgG2a) and cytokine levels, especially TNF-α and IL-12, compared with the control groups treated with either MBP or PBS. In conclusion, rOmpA should be highly considered as a future subunit vaccine for brucellosis, and further studies regarding rOmpA and its protective ability are suggested.
