Observation Results

<em>This research has the aim of increasing the skills to write reports on the results of simple environmental observations. The subjects of this study were class II SD Negeri 2 Kritig, totaling 15 students. This research was conducted in 3 cycles. Each cycle consists of 4 stages, namely planning, implementing and observing, and reflecting. There are two assessments carried out in this study, namely an assessment of the content of the report and an assessment of the writing. The results of his research for the assessment of report content in the first cycle of completeness reached 80% and increased in cycles II and III to reach 100%. Then for the written assessment, completeness reached 26.67% in the first cycle increased to 67% in the second cycle and 86.7% in the third cycle. Furthermore, the average final score in cycle I reached 73.99, increased to 78.75 in cycle II and reached 80.2 in cycle III. So the conclusion is that through the use of instructional video media it can improve the skills of writing reports on environmental observations of grade II students of SD Negeri 2 Kritig.</em>

SUMMARY Objectives: This randomized clinical trial tested the three-month desensitizing effect of two protocols using nano-hydroxyapatite formulations compared with Pro-Argin and fluoride varnish. Methods: Twenty-eight subjects with 137 teeth presenting dentin exposure with a minimal hypersensitivity of four on the visual analog scale (VAS) took part of this study. The subjects were randomly assigned to four groups: Desensibilize Nano-P paste (20% hydroxyapatite [HAP], potassium nitrate, and sodium fluoride [NaF]; 9000 ppm fluoride [F]); Desensibilize Nano-P associated with experimental home-care pastes (10% HA, potassium nitrate, and NaF; 900 ppm F); Pro-Relief professional paste (8% arginine with Pro-Argin technology) associated with home-care toothpaste (8% arginine, sodium monofluorophosphate, 1450 ppm F); and Duraphat professional varnish (NaF varnish, 22,600 ppm F). The professional treatments were performed in weekly appointments over three weeks. The home-care products were used continuously for three months. A VAS was used to assess the tooth sensitivity response after standardized evaporative stimulus at baseline and after one month and three months. The baseline score was deducted from the final score, and the means were analyzed using nested analysis of variance, while the comparison between times was performed by a general linear model (p&lt;0.05). Results: At the first month all treatments were effective, but there were no significant differences among them (p=0.94). At the third month, despite the fact that NaF varnish had the lowest effect in reducing hypersensitivity, no significant difference was found among the treatments (p=0.09). Only Pro-Relief increased its effect over time (p=0.049). Conclusions: Nano-hydroxyapatite formulations (with or without home-&gt;care product association) were as effective as the other treatments in reducing dentin hypersensitivity over three months.

This study aims to determine the effect of the TGT type cooperative model (Teams Games Tournament) on student learning motivation. Researchers conducted research at SDN Cangkring Turi Prambon. The type of research used is a quantitative approach to experimental methods with Pre Experimental design. The type used is One Group Pretest-Posttest Design. The subjects taken were 21 grade II students at SDN Cangkring Turi Prambon. TGT learning model is used to find out the effect of the TGT learning model on the learning motivation of class II students of SDN Cangkring Turi Prambon. The results of this study indicate that the analysis of the data obtained is tcount of 20.80 and ttable of 1.725. Thus tcount > ttable, namely 20.80> 1.725, there is the effect of the TGT model on the learning motivation of class II students of SDN Cangkring Turi Prambon. While the results of the eta squared test obtained 0.955 ≥ 0.14 has the meaning of great influence.

Introduction: The students of a country like Bangladesh, where language of medical education is completely English, suffer from a lot of problems in grasping English and also Latin and Greek terms used in English.Objective: This study was aimed to estimate the extents and to identify the nature of the problems faced by the undergraduate students in different aspects of English used in Anatomy.Methods: The study was conducted on 191 third year medical students, who had just passed the Anatomy portion of their undergraduate course from two renowned government medical colleges and one private medical college of Bangladesh. A written assessment test of students' performance was designed using two sets of questions as the instrument of the test. Each student was graded, according to the percentage frequency of correct responses, as having Grade IV difficulty (up to 20%), Grade III difficulty (20.01% to 40%), Grade II difficulty (40.01% to 60%), Grade I difficulty (60.01% to 80%) and Grade 0 with 'no difficulty' (above 80.01%). Comments were also collected from the students regarding their problems with English used in Anatomy.Results: An average of only about 48.2% responses on 'English used in Anatomy' was correct, ranging from about 20 to 70%. An arbitrary grading of difficulty level showed that 75% of the students were suffering from Grade II to Grade III difficulties. Performance of the students showed that the undergraduate medical students of Bangladesh were facing varying but noticeable amounts of difficulty with most of the areas of 'English used in Anatomy'.Conclusion: Organized, regular ways of dealing with these problems should be devised taking into consideration the specific aspects showing weakness and based on principles of terminology and English rather than on individual terms or words. Key words: English used in Anatomy; difficulty; undergraduate medical student DOI: 10.3329/jafmc.v6i2.7272JAFMC Bangladesh. Vol 6, No 2 (December) 2010 pp.32-36

AbstractPolyhydroxyalkanoate synthase, PhaC, is a key enzyme in the biosynthesis of PHA, a type of bioplastics with huge potential to replace conventional petroleum-based plastics. While two PhaC structures have been determined recently, the exact mechanism remains unclear partly due to the absence of a tunnel for product passage. The PhaC fromAquitaleasp. USM4, PhaCAq, was characterised and showed aKmof 394 µM and akcatof 476.4 s−1on the 3HB-CoA substrate. A model based on the structure of the closely related PhaC fromCupriavidus necator, PhaCCnrevealed a three-branched tunnel at the dimeric interface. Two of the branches open to the solvent and serve as the putative routes for substrate entrance and product exit, while the third branch is elongated in a PhaC1 model fromPseudomonas aeruginosa, indicating a function of accommodating the hydroxyalkanoate (HA) moiety of the HA-CoA substrate. Docking of the two tetrahedral intermediates formed during catalysis suggests a PHA elongation mechanism that requires the HA moiety of the ligand to rotate ~180°. Both classes I and II PhaCs share a common mechanism for polymer elongation, and substrate specificity is determined in part by a bulky Phe/Tyr/Trp residue in the third branch in class I, which is conserved as Ala in class II to create room for longer substrates. The PhaCAqmodel provides fresh insights into a general PhaC mechanism, pinpointing key residues for potential engineering of PhaCs with desirable characteristics.
