Posterior contraction rates for non-parametric state and drift estimation

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).

Diversity of Indonesian Batik hanging area. One of the very well-known Indonesian batik is Batik Madura. Batik Madura has become a pride for Indonesia, especially for Madura. The purpose of the study is to model the Sumenep pride to Batik Madura and to see the level of risk or tendency of batik madura pride for the community group Sumenep. This research method uses a non parametric regression used a non-parametric regression because the dependent variable in this study is the variable Y are variables not normally distributed. The results of this study states that the level of risk of the village in Sumenep proud of batik is almost 5 times higher than the islands while people in this city who live in the district town at risk Sumenep proud of Batik Madura 8-fold compared to the archipelago. So it can be concluded that the city is much more proud of batik than those who reside in rural areas especially those who reside in the islands. This study uses data from 100 questionnaires were analyzed using logistic regression analysis. The conclusion of this study is the pride of the batik model as follows: Function logistic regression / logit function: g (x) = 0,074 + 1,568X4(1)+2,159X4(2 this is case the islands as a comparison, X4(1) is the place to stay in the village and X4(2) is the place to stay in town, so the Model Opportunities p(x) = EXP(g(x))/1+EXP(g(x)). Hopes for further research is to conduct research on the development of batik in an integrated region, the need to be disseminated to potential areas of particular potential in Madura batik, especially for residents who reside in the Islands.Keywords: Pride, Batik, Sumenep.

Penelitian ini bertujuan untuk mengetahui apakah pelatihan “mengasuh dengan empati, mengasuh dengan hati” dapat meningkatkan pengetahuan dan keterampilan parental empathyibu-ibu bhayangkari. Penelitian ini berbentuk pelatihan dengan dasar pikiran experiential learningyang diberikan pada sekelompok ibu-ibu bhayangkari yang memiliki anak usia 3 sampai 5 tahun, dan merupakan penelitian dengan one group pretestdan posttest design. Penelitian ini dilakukan di Jakarta Timur dengan melibatkan partisipan sebanyak 13 orang ibu yang memiliki anak usia 3-5 tahun dengan diberikan pelatihan sebanyak 10 sesi dalam waktu 4 hari. Pretest dan posttest diberikan sebelum dan setelah pelatihan dengan instrumen yang mengukur kemampuan parental empathy berdasarkan Eagle dan Bylund Makoul yang dirancang oleh peneliti. Hasil pretestdan post testdiuji dengan uji non parametric Wilcoxon Signed Rank menunjukkan level signifikansi p.value0,003 (<0,05). Hasil ini berarti terdapat perbedaan yang signifikan antara nilai pre-testdan post-test. Dengan demikian dapat disimpulkan bahwa pelatihan “Mengasuh dengan Empati, Mengasuh dengan Hati” dapat meningkatkan pengetahuan dan keterampilan parental empathyibu. Rekomendasi untuk penelitian selanjutnya adalah melakukan kunjungan rumah kepada partisipan agar partisipan memperoleh umpan balik langsung dan kemampuan parental empathy akan lebih meningkat.
