of a fast Fourier transform algorithm. The frequency domain was divided into 3 bands: VLF (0 ~ 0.04 Hz), LF (0.04 ~ 0.15 Hz) and HF (0.15 ~ 1.00 Hz). Heart rate was 74.4±2.1 beats/min at rest and showed a steady increase during treadmill exercise with increasing speed and grade up to 196.7±5.0 beats/min. Total power of HRV was 35.0±6.7 (beats/min)2 at rest and progressively decreased during exercise down to 1.9±0.3 (beats/min)2. The %VLF power of HRV was 34.5±3.7 % at rest and showed no...

In the population genetic analysis based on the CP gene sequences, all 107 AMV isolates fell into two main clades (A, B) and isolates of clade A were further divided into three groups with significant subpopulation differentiation. The results indicated moderate genetic variation within and no clear geographic or genetic structure between the studied populations, implying moderate gene flow can play an important role in differentiation and distri- bution of genetic diversity among populations....

we report identification and functional analysis of a putative JmjC-domain-containing histone demethylase in Magnaporthe oryzae. Through bioinformatics analysis, we identified seven genes, which encode putative histone demethylases containing JmjC domain. Deletion of one gene, MoJMJ1, belonging to JARID group, resulted in defects in vegetative growth, asexual reproduction, appressorium formation as well as invasive growth in the fungus. Western blot analysis showed that global H3K4me3 level...

Play is a universal code, which mirrors the all-round development of a child. Play development reflects the emergence of early cognitive skills in children. The current study profiles the developmental trends of different types of play during the free and structured play scenario in South India. The sample included 48 pre-school children, aged between 3.6 to 5.6 years. Children’s play was recorded in two scenarios, which included free Play (spontaneous Play without any restrictions) and...

The issue of assessment is critical to children’s development. The adoption of suitable assessment tools/strategies would aid the process of judgment and decision making on children’s developmental milestones and learning. Therefore, this study examined the assessment procedure adopted for the pre-primary school children in Nigeria and to determine their developmental appropriateness to children. A descriptive survey design was adopted for the study. One hundred and sixty-two public schools...

an illustration with real-world data. Specifically, multilevel multiple-group latent profile analysis (MMLPA) models were fitted following seven steps to classify students according to their perception of instructional practices in science classrooms and to compare the latent profiles of two countries using Korean and Japanese data from the Programme for International Student Assessment (PISA) 2015. The results are as follows. First, multilevel latent profile analysis models fit better than...

주파수 영역 민감도 해석법은 동적 시스템의 전달함수에 대한 설계 파라미터의 변화에 의한 효과를 파악하기 위해 사용되어 왔으며, 이때의 민감도 함수는 시스템 설계 파라미터에 대한 시스템 전달 함수의 편미분 값이다. 일반적으로 종래의 주파수 영역 민감도 해석은 직접 미분법이나 라플라스 변환이 사용되어 왔다. 라플라스 변환을 사용하는 경우에 시스템의 차수가 증가할수록 역행렬 조작은 매우 많은 시간을 필요로 하며 또한 어려운 작업이다. 본논문에서는 이러한 다점을 보완하기 위하여 푸리에변환을 이용한 민감도 기법을...
