OBJECTIVE: To assess differences in how orthodontists and laypersons perceive a reduction in dentogingival display on smiling. METHODS: Sixty examiners from both genders (30 laypersons and 30 orthodontists) evaluated photographs of spontaneous smiles of two subjects , one male and one female. Based on the original images, smile height was modified by means of an image manipulation software program. The examiners assigned scores ranging from 0 to 10, according to the level of pleasantness. Method reproducibility was examined using the Wilcoxon test, while the Friedman and Wilcoxon tests (p < 0.05) were employed to observe intra- and interexaminer differences, respectively. RESULTS: No differences were found between the groups of examiners - in terms of esthetics - in response to changes in smile height of both genders . However,men smile had lower acceptability than the women smile. A mild reduction in dentogingival display on smiling (2 mm) was not perceived by either laypersons or orthodontists (p > 0.05). CONCLUSIONS: women smiles achieved higher scores than men smiles however, samples involving a larger number of subjects in each group are required to ensure whether or not this finding is linked to the subjects gender.

Es wird untersucht, unter welchen Bedingungen der von Buck jüngst vertäfelte Vorzeichenrangtest nach Pbatt wirksamer ist als der nullenreduzierte Wilcoxon-Test. Schlußfolgernd wird empfohlen, den PBATT-Test immer dann gegenüber dem Wilcoxon-Test zu präferieren, wenn mit Ausreißerdifferenzen gegen die unter der Alternativhypothese vorausgesetzte Behandlungswirkung gerechnet wird.

Periode emas tumbuh kembang seorang anak dimulai sejak anak dalam kandungan hingga berusia dua tahun. Wanita hamil dan anak-anak usia dibawah 5 tahun berada pada risiko tertinggi micronutrient deficiencies (MNDs), masalah pertumbuhan, penurunan intelektual, komplikasi perinatal dan meningkatnya risiko morbiditas dan mortalitas. Oleh karena itu ibu hamil memerlukan program edukasi tentang nutrisi yang tepat untuk kesehatan ibu dan janin. Edukasi berbasis keluarga sesuai program keluarga sehat dapat meningkatkan intensi untuk mengubah perilaku kesehatan. Menurut Theory of Planned Behavior (TPB), bahwa intensi untuk mengubah perilaku dipengaruhi oleh sikap, norma subjektif dan persepsi kontrol perilaku. Penelitian ini bertujuan mengidentifikasi pengaruh edukasi berbasis keluarga terhadap intensi ibu hamil untuk optimalisasi nutrisi pada 1000 Hari Pertama Kehidupan di wilayah kerja Puskesmas Neglasari, Kota Bandung. Desain penelitian menggunakan quasi eksperiment, pre-test and posttest with control group design.

Purpose: to investigate the diagnostic opportunities of contrast  magnetic resonance imaging with the effect of magnetization transfer effect in the diagnosis of focal metastatic lesions in the brain.Materials and methods.Images of contrast MRI of the brain of 16  patients (mean age 49 ± 18.5 years) were analysed. Diagnosis of  the direction is focal brain lesion. All MRI studies were carried out  using the Toshiba Titan Octave with magnetic field of 1.5 T. The  contrast agent is “Magnevist” at concentration of 0.2 ml/kg was  used. After contrasting process two T1-weighted studies were  performed: without T1-SE magnetization transfer with parameters of pulse: TR = 540 ms, TE = 12 ms, DFOV = 24 sm, MX = 320 × 224  and with magnetization transfer – T1-SE-MTC with parameters of pulse: ΔF = −210 Hz, FA(МТС) = 600°, TR = 700 ms, TE = 10 ms,  DFOV = 23.9 sm, MX = 320 x 224. For each detected metastatic  lesion, a contrast-to-brain ratio (CBR) was calculated. Comparative  analysis of CBR values was carried out using a non-parametric  Wilcoxon test at a significance level p < 0.05. To evaluate the  sensitivity and specificity of the techniques in the detection of  metastatic foci (T1-SE and T1-SE-MTC), ROC analysis was used. The sample is divided into groups: 1 group is foci ≤5 mm in size, 2  group is foci from 6 to 10 mm, and 3 group is foci >10 mm. Results.Comparative analysis of CBR using non-parametric Wilcoxon test showed that the values of the CBR on T1-weighted  images with magnetization transfer are significantly higher (p  <0.001) that on T1-weighted images without magnetization transfer. According to the results of the ROC analysis, sensitivity in detecting  metastases (n = 90) in the brain on T1-SE-MTC and T1-SE was  91.7% and 81.6%, specificity was 100% and 97.6%, respectively.  The accuracy of the T1-SE-MTC is 10% higher in comparison with  the technique without magnetization transfer. Significant differences (p < 0.01) between the size of the foci detected in post-contrast T1- weighted images with magnetization transfer and in post-contrast  T1-weighted images without magnetization transfer, in particular for  foci ≤5 mm in size, were found. Conclusions1. Comparative analysis of CBR showed significant (p < 0.001)  increase of contrast between metastatic lesion and white matter on  T1-SE-MTC in comparison with T1-SE.2. The sensitivity, specificity and accuracy of the magnetization transfer program (T1-SE-MTC) in detecting foci of  metastatic lesions in the brain is significantly higher (p < 0.01), relative to T1-SE.3. The T1-SE-MTC program allows detecting more foci in comparison with T1-SE, in particular foci of ≤5 mm (96% and 86%, respectively, with p < 0.05).

Attachment behaviors are behaviors experienced by children when they would leave their homes and families to join his friends at school he regarded as strangers. This behavior can interfere with the functioning life of the child so that the child can not be independent, and parents should be involved more in the activities of children. The study aimed to determine the effect of economic token therapy for reducing the attachment behavior among Kindergarten Students. The design of this study was quasi experimental with pre and post with control group. By using multistage random sampling and consecutive sampling technique with a total sample of 68 people who experienced attachment behavior. Consisted of 34 peoples as intervention group and 34 peoples as control group. Bivariate analysis using Wilcoxon test and mann-whitney test. The results showed that there were significant differences of attachment behavior before and after entering the token economy intervention in the intervention group compared with those in the control group (p = 0.000). Token economy therapy has positive effect to reduce attachment behavior of kindergarten student at the beginning of learning process in the kindergarten school. The application of economic token is recommended to overcome the attachment behavior of existing preschool children in schools and in the general public health services.   KEY WORDS: Attachment behavior, Token economy, Kindergarten students.
