ANALYSIS AND RESEARCH ON THE KEY FACTORS OF SPORTS IN MAINTAINING HUMAN HEALTH

ABSTRACT Introduction The research on the promotion of physical fitness of the human body by exercise has also attracted widespread attention in sports and rehabilitation medicine. Object This article uses ultrasound to study the bone density health of the human body, thereby establishing the relationship between sports and bone density health. We hope to use the research results of this article to improve people’s awareness of sports health. Method We used ultrasound to test the bone mineral density of two groups of students (exercise group and non-exercise group) to explore the relationship between different sports items and the students’ bone mineral density. Results There is a significant difference in bone density between the two groups of students. There is no gender difference in bone density. Conclusion Students need to strengthen physical exercise in the growth and development stage to improve bone density. Level of evidence II; Therapeutic studies - investigation of treatment results.</div

LONG-TERM EFFECTS OF JUMP ROPE TRAINING ON ATHLETES’ PHYSICAL HEALTH

ABSTRACT Introduction Jumping rope is an aerobic exercise that requires little time, consumes a high energy level, and does not require sizeable physical space or high investments. Although there are extensive studies in the literature on its short- and medium-term benefits, long-term responses are still inconclusive. Objective Explore the long-term effects of jump rope training on the physical health of athletes. Methods A randomized study was conducted before the protocol of regular physical education activities. The experimental group was differentiated by practicing a specific long-term jump rope protocol. Interferences of external factors were controlled during the 12 weeks of the experiment. Data analysis, observation of changes in fitness indicators, and statistical control were discussed. Results The mean time for a 50-meter run was 8.85s versus 9.63s before the experiment. A gain of 0.78s, representing an 8% increase over the speed. The girls’ mean value before the experiment was 9.62s versus 9.18s after the experiment. The gain of 0.44 seconds represented an increase of 4.6%. Well-being perception was improved with injuries reduction over the control group. Conclusion Long-term jump rope training has been shown to improve fitness and reduce injuries in athletes and has the potential to become a viable option for physical education training. Evidence Level II; Therapeutic Studies - Investigating the result.</div

China and India: opportunities and threats for the global software industry

The penetration of software in all facets of life has been so significant that it is not an exaggeration to say that we live in a software-enabled world today. This has led to a flourishing, multi-billion dollar global software industry. However, over the last decade, several economic, demographic and technological factors have substantially impacted the global software industry landscape. Two very prominent developments have been globalization of software development, and emergence of India followed by China as two major software nations. Although the development trajectory of software industry in China has been different than that of India, both China and India are now competing for achieving supremacy in the global software industry.</p

Software industry in China and India

The last decade has witnessed the emergence of China and India as the two most significant economies in the global competitive landscape. The prominence of China and India is due not only to rapidly growing local markets but also a phenomenally increasing concentration of economic and innovative activities that is taking place in these two countries. Particularly in the context of the global software industry India has acquired the repute of a leading 'software nation,' whereas China is fast gaining ground and emerging as a serious player. Various economic indicators, including the flow of FDI, testify the significance of India and China in the global software industry landscape.</p

Image1_Comparative Chloroplast Genomics and Phylogenetic Analysis of Thuniopsis and Closely Related Genera within Coelogyninae (Orchidaceae).JPEG

The genus Thuniopsis was recently proposed for a rare orchid species T. cleistogama formerly classified in the genus Thunia. The relationships between Thuniopsis and its related genera have not yet been conclusively resolved. Recognition of the genus provides a new perspective to illustrate the morphological diversity and plastome evolution within Coelogyninae. In this study, we sequenced and assembled complete chloroplast (cp) genomes for three accessions of Thuniopsis cleistogama and two accessions of Thunia alba. A total of 135 genes were annotated for each cp genome, including 89 protein-coding genes, 38 tRNA genes, and eight rRNA genes. The ENC-plot and neutrality plot analyses revealed that natural selection dominated over mutation pressure in their evolutionary process. Specially, we found that selection played a vital role in shaping the codon usage in Thunia alba cp genome. General characteristics of the cp genomes were further analyzed and compared with those published plastomes of four other related species. Despite the conserved organization and structure, the whole individual cp genome size ranged from 158,394 bp to 159,950 bp. In all the examined plastomes, sequences in the inverted repeat (IR) regions were more conserved than those in the small single copy (SSC) and large single copy (LSC) regions. However, close examination identified contraction and expansion of the IR/SSC boundary regions, which might be the main reason for the cp genome size variation. Our comparative analysis of the cp genomes revealed that single nucleotide polymorphisms (SNPs) and insertions/deletions (InDels) provided valuable information for identifying genetic variations within and among genera. Furthermore, sequence variations in the protein-coding regions were more conserved than those in the non-coding regions. We selected eight divergence hotspots with nucleotide sequence diversities (Pi values) higher than 0.08. Most of these polymorphisms were located in the intergenic regions. Phylogenomic analyses recovered largely congruent relationships among major clades and strongly supported the monophyly of Thuniopsis. The results obtained in this study can improve our understanding of the classification of this enigmatic genus. The chloroplast genomic data presented here provide valuable insights into the phylogeny and evolutionary patterns of the Coelogyninae as well as the orchids as a whole.</p
