Within the lay literature, and social media in particular, there is often debate about the age at which a horse should be started and introduced to racing or sport. To optimize the welfare and longevity of horses in racing and sport, it is important to match exercise with musculoskeletal development and the ability of the musculoskeletal system to respond to loading. The justification for not exercising horses at a certain age is often in contrast to the scientific literature and framed, with incorrect generalizations, with human growth. This review provides a relative comparison of the growth and development of the horse to the descriptors used to define growth and development in humans. Measures of physeal closure and somatic growth demonstrate that the horse completes the equivalent of rapid infant growth by weaning (4–6 months old). At approximately 11 months old, the horse completes the equivalent of the childhood phase of growth and enters puberty. At 2 years old, the horse has achieved most measures of maturity used within the human literature, including the plateauing of vertical height, closure of growth plates, and adult ratios of back length:wither height and limb length:wither height. These data support the hypothesis that the horse evolved to be a precocious cursorial grazer and is capable of athletic activity, and use in sport, relatively early in life.

AbstractIntroductionChanges in human growth and development depend on genetic and environmental factors. In the case of Slovenia, the environmental factors changed as a result of the period of socio-economic transition that the country underwent between 1991 and 2013. The authors used anthropometric techniques to evaluate differences in body height, proportions and sexual maturity in 1,221 adolescents aged 14 in 1993, 2003 and 2013.MethodsData was collected as a part of the ACDSi study, which has monitored children’s somatic growth and motor development every decade over the last 40 years.ResultsBetween 1993 and 2013, a trend (p=0.08) towards increased body height was observed in males. The comparison of age at peak height velocity (PHV) between generations demonstrated a trend (p=0.07) of earlier entry into puberty in adolescents in 2013 compared to those in 1993. The leg-to-body height ratio increased (p<0.05) with every decade in males, while in females it decreased (p<0.05) in 2013. Similar trends were observed in the leg-to-trunk ratio. Contemporary generations experienced PHV at a younger age (p<0.05), which is true for both genders even in adolescents born no more than two decades (1993 (2013) apart. In both generations, females experienced PHV sooner than their male peers.ConclusionThe authors assume that females of the 2013 generation reached puberty earlier than females of older generations. It is most likely that, unlike females from older generations and unlike males, they were already at the stage of trunk growth at the time of the measurements, which explains the observed changes in their trunk length, leg-to-body height and leg-to-trunk ratios in comparison to earlier generations.

Moral planting to children from an early age is very important considering that in the era of an increasingly global era, moral education as the basis of self-discipline to be an internal control tool in behaving consistently in religion. A child is naturally created in a state ready to receive good and evil. The habituation of religious and moral values ​​for early childhood is very important to apply as early as possible to the most basic foundation in the process of growth and development of children. The objectives of this research are (1) To describe TPQ Al-Khumaier program, (2) To describe the application of moral values ​​to students by TPQ Al-Khumaier teacher (3) To know the obstacles in applying moral values ​​to the students of TPQ Al-Khumaier and looking for a solution. The results of this study indicate that the program TPQ Al-Khumaier has been implemented according to the program prepared by the school in collaboration with Kemenag Pekanbaru. The application of santri moral values ​​has been practiced in the activities and the process of habituation and modeling of the teachers. The obstacles are the duration of the meeting, social outside TPQ, including social media at home and in the neighborhood where students live.

Aspects of human growth and development have been studied since the inception of psychology as a field of science. The impact of the quality of mothering on children has been highly researched. However, little attention has been paid in the professional literature to the experiences of mothers as their children move through developmental stages. The focus of this hermeneutic phenomenology study was to investigate how mothers’ experiences of their child's growth and development changed her perceptions of her identity and herself. Participants were eight women who had launched the oldest child from the home within the last 2 years. Extensive data analysis and triangulation procedures were conducted to develop themes. Universal themes experienced by all participants were categorized as internal (questioning, comparison, being purposeful, and feeling supported) and external (experiencing joy). Some participant experiences were influenced by incidental themes such as subsequent children, expectations versus reality, and spirituality. Participants’ experience of their mothering role was also impacted by the process of letting go through the developmental progression of their children. Clinical implications are discussed.

Currently the development of children is the center of attention for families and schools, where at this time technology or social media in the current digital era has a very good and bad impact on children if parents and teachers do not monitor children in using social media. the impact of the misuse of technology, it must continue to guide children. Education in schools is very helpful for the growth and development of children. Because children who receive education at school understand more about some of the things that can be learned at school and children's behavior is more functional because it is shaped by observation and influenced by what they get. When parents or teachers educate children well, the child's association will be better. Because nowadays, especially the use of technology or social media, it really has an impact on children.

  Brazil has made a wide development and contribution in the field of Public Health. These contributions have maximized public health decision-making, which is a factor of great importance for the maintenance of health of a given population, either in the prevention of disease, as is the case of immunizations or with actions in Health Promotion, improving the quality of life of the affected population. Thus, the Journal of Human Growth and Development has contributed enormously to the dissemination of knowledge, not only in Brazil but also in the world making a major effort with its publications in English which is the preferred language of the modern scientific world. It was evidenced the importance of research in the investigation of better ways to obtain the public health of a given community, bringing discussion of themes that involve aspects of human growth and development such as nutritional aspects, sexuality, motor development, covering situations and diseases as obesity, cerebral palsy, dyslexia and violence. The Journal of Human Growth and Development has maintained the tradition of approaching the different aspects that involve clinical practice for people and for Public Health.
