Persepsi Orang Tua Peserta Didik terhadap Mata Pelajaran Penjasorkes di Sdn 9 Desa Sei Kelambu Kecamatan Tebas Kabupaten Sambas

The formulation of the problem in this study is How Parents Perceptions Learners to Learning penjasorkes in SDN 9 Village Sei Kelambu Tebas District Sambas ?. The purpose of this research is to know the perceptions of parents of learners on learning physical education of sports and health (Penjasorkes) at SDN 9 Sei Kelambu Village Tebas Subdistrict Sambas District. The method used is quantitative descriptive method. Sample amounted to 27 parents of learners while the population was as many as 108 people. Using indirect communication techniques and documentary study techniques. Data analysis is done by descriptive percentage. The results of data analysis are: 1) Parents' perceptions of the benefits of penjasorkes amounting to 76.26%, this result shows that when following the learning penjasorkes learners have shown good benefits, especially in SDN 9 Village Sei Kelambu District Tebas District Sambas, the children look very enthusiastic about learning pemas. 2) Perceptions of parents of learners on penjasorkes assessment amounted to 80.55%. This means that parents' assessment of the subject of physical and health education (penjasorkesS) is very good for their children for example can teach children respect each other, bear the risk of making mistakes in exercising, teach children to obey the rules during the game, avoid cheating in playing with his friends, practice responsible attitudes in daily life, and teaches children to accept defeat while competing

Factors Influencing the Concentrations of the Large Neutral Amino Acids in the Brain and in the CSF of Dogs After Portacaval Anastomosis

Portal-systemic shunting of blood is associated with hyperammonemia, an increased glutamine concentration in brain, an altered plasma neutral amino acid pattern, and high levels of several of the large neutral amino acids in brain. Since some of these amino acids are precursors for neurotransmitters and for other potentially neuroactive substances, high CNS levels of these amino acids may contribute to the development of encephalopathy. In order to determine the relative importance of changes in brain glutamine levels and changes in competition among the neutral amino acids for blood-brain transport, we measured the concentrations of the large neutral amino acids in plasma, cisternal cerebrospinal fluid and in brain tissue from various regions of dogs after end-to-side portacaval shunt. Although the changes in CSF amino acid levels correlated partially with altered amino acid plasma competitor ratios, better correlations were observed with the elevation of CSF glutamine. These results suggest a model of blood-brain amino acid transport in which a high level of glutamine in brain extracellular fluid competes with other neutral amino acids for efflux from brain, thus raising brain amino acid levels after portalsystemic shuntin
