This study evaluated the mechanical strength correlated to the percentage of the total volume of weld and porosities of Co-Cr alloy joints welded with TIG technique. Thirty specimens were perpendicularly sectioned to the long-axis and rejoined by using X30-shaped joint design with TIG welding. They were divided into 3 groups (n=10): the CG1 with a 60-A depth and 90-ms pulse; the CG2 with a 60-A depth and 120-ms pulse and the CG3 with a 60-A depth and 160-ms pulse. The specimens were submitted to nondestructive tests: radiographic inspection, penetrant liquid and Micro- CT (to calculate the percentage of the total volume of welding and the porosities) and then tested with 3-point bending. The fracture surfaces were analyzed with scanning electron microscopy (SEM). The data were statistically analyzed with 1-way ANOVA and the Tukey post hoc test for all the variables which were analyzed: flexural strength, total volume of weld and porosities. Pearson correlation test was also applied (ɑ=.05). The 1-way ANOVA showed that the factors machine parameters were not significant for flexural strength values (P=.231), the total volume of weld (P=.057) and porosities (P=.057). There are no significant relationships between any pair of variables after Pearson correlation test (P >.050). This, suggesting that the three machine regulation can be an option for joining prefabricated Co-Cr rods in this kind of union.

The general objective of this work is to identify a set of electronic governance practices for the executive power of the Brazilian States and Federal District, to measure and relate them to the economic and social development of the respective States and Federal District. In order to achieve this objective, the authors first used bibliographic research to build the theoretical platform about electronic governance and controllership in public management and the identification of electronic governance practices; next, a measurement and monitoring index of the development of electronic governance – 2013 is proposed. The Pearson correlation test was performed in order to verify the correlation between electronic governance and economic and social development indexes – GDP AND GDP per capita – and HDI and Gini, respectively. Lastly, the 2009 electronic governance index was used for comparison purposes. By comparing the results of the correlation and the percentage of the implemented practices, it was then concluded that the States with the highest GDP, the highest HDI and the lowest Gini are those which have the highest number of implemented electronic governance practices.

Abstract: Patients with type 2 diabetes mellitus (T2DM) are characterized by an acceleration of thrombopoiesis, an increase of platelet turnover, and a decrease of platelet survival time. These conditions affect the platelet count that manifest as an increase of the proportion of large and reactive platelets which are more thrombogenic. This study aimed to obtain the correlation between the platelet count and the platelet aggregation value in T2DM patients. This was an observational analytical study using the Pearson correlation test. Subjects were 30 T2DM outpatients at Endocrine-Metablolic Clinic of Prof. Dr. R.D. Kandou Hospital Manado. Blood samples of all patients were examined for platelet count and platelet aggregation value. The results showed that most of the subjects were ≥50 tahun (86.7%). Mean thrombocyte count was within normal level. Platelet aggregation values of the ADP 10 µm showed hypoaggregation, meanwhile of the ADP 5 µm showed normoaggregation The Pearson correlation test showed that there was no significant correlation between the platelet count and the platelet aggregation value, either using 10µm ADP (P = 0.22) or using 5µm ADP (P = 0.08). Conclusion:Keywords: platelet count, platelet aggregation, T2DMThere was no significant correlation between the platelet count and the platelet aggregation values in patients with type-2 diabetes mellitus at Endocrine-Metabolic Clinic of Prof. Dr. R.D. Kandou Hospital Manado.   Abstrak: Pada pasien diabetes melitus tipe 2 (DMT2) terjadi percepatan trombopoiesis, peningkatan pergantian trombosit, dan penurunan waktu hidup trombosit.

Recurrent aphthous stomatitis (RAS) is an oral mucosal disease which was more prevalent in women than men. Study has shown that zinc deficiency associated with the occurance of RAS. Other study also have shown that vitamin D deficiency contributed in RAS. However, there is no study yet that reveal the association between serum zinc and vitamin D/25 (OH)D in women with RAS. To investigate the association between serum zinc and vitamin D/25(OH)D in women with RAS. Thirty two women patients with RAS who meet the inclusion criteria participated in this study. The inclusions criteria was non pregnant women who have been diagnosed RAS and did not have other oral diseases. The exclusions criteria were those who have systemic diseases, taking medications including multivitamin, and have bad habits (i.e. smoking). Data concerning characteristic of subjects, severity of RAS, serum vitamin D/25(OH)D, and zinc were collected and presented descriptively. The correlation between serum zinc and Vitamin D/25(OH)D was analyzed using Pearson correlation test with 95% confidence interval. This study has been approved by Medical and Health Ethics Committe, Faculty of Medicine, Universitas Gadjah Mada, Yogyakarta. All subjects of this study have low mean value of serum vitamin D/25(OH)D (11.08 ± 3.11 ng/mL) and categorized with vitamin D deficiency. The subjects also have low mean value of serum zinc (54.78 ± 9.19 μg/dL) and seventy percent subjects have mean value of serum zinc below normal. The result of Pearson correlation test showed that there was a significant positive correlation between mean serum zinc and Vitamin D/25(OH)D (r= 0.351, p<0.05) in women with RAS. Serum zinc associated with vitamin D/25(OH)D and play role in pathogenesis of RAS.
