This quasi-experimental research examined the effects of the process/genre approach (PGA) with the integration of blogs in EFL university-level students’ writing classrooms. This was a mixed-method study in which the participants’ essays and adopted questionnaires contributed to accumulating quantitative data while the interviews and observations provided qualitative data. The study took place over ten weeks at a university in central Taiwan in which paper-pencil instruction was applied in the control group, while blog instruction was employed for the experimental group. The students’ essays were computed by applying a paired-sample t-test, and the questionnaires were analysed by applying a Wilcoxon signed-rank test to determine whether there were any statistically significant differences in terms of the students’ writing performance and perceptions toward the PGA and blog writing after comparing the results of the pre-test and the post-test. The qualitative data was analysed to provide in-depth evidence to support the quantitative results. After the data analysis was completed, the paired-sample t-test demonstrated that there were significant differences in terms of the students’ writing performance in both groups, which demonstrates how the PGA developed the EFL university students’ writing performance. Because the students had more interactive opportunities to be exposed to the language inputs, this approach facilitated their English writing performance. The Wilcoxon signed-rank test presented that the students revealed positive attitudes toward writing blogs and also positive affections toward blog writing because they had higher levels of satisfaction and lower levels of apprehension when blogging. Moreover, there was a significant difference in terms of the factor of “learning with peers” in the control group since the PGA provided more interactive and communicative opportunities. The students also indicated greater understanding about their writing samples in the experimental group, since they were allowed to refer to the instructional contents on the blogs anytime and anywhere.

Most prevalent diseases in the elderly is of Non-Infectious Diseases, one of which is hypertension. Hypertension is a silent killer which symptoms can various in each others and similar with the symptoms of other diseases. 25.8% hypertension, causes at least 45% of deaths due to heart disease and 51% of deaths due to stroke. The kind of treatment consist of pharmacology and nonpharmacology. One of the non-pharmacology tretment is acupressur therapy The purpose of this study to determine the emphasis effect of acupressure points Taixi (Ki3), Sanyinjiao (SP6) to reduction blood pressure in the elderly with hypertension in PSTW Jember. The study design used is quasy experiment one group pretest posttest. Samples taken by simple random sampling, that is the elderly aged over 60 years with hypertension in Jember PSTW as many as 20 person. After the acupressure therapy mostly elderly blood pressure is decreased. The results were analyzed using SPSS with paired sample t-test if normal data distribution and the Wilcoxon signed rank test if data distribution is not normal. Results of analysis using paired samples t-test showed that the value of systole p = 0.001 (p < α). This research of the value of MAP p= 0.000 (p < α) and diastole using the Wilcoxon signed rank test was obtained p = 0.004 (p < α ) mean that suppression effect of acupressure points Taixi (Ki3) and Sanyinjiao (SP6) effective to decrease blood pressure in the elderly with hypertension in PSTW Jember

AbstractThe evaluation of geoscience data is a far-reaching topic which cannot be systematically covered. The purpose of inferential statistics is to harness useful information from data for making decisions. This paper conducts in-depth statistical study for the Bursa-Wolf and Molodensky Badekas models of the three-dimensional transformation parameters. We also considered the combined and observation equations scenarios of these methods for the comparative study. Four key indicators are conducted to evaluate the performance of the two transformation models according to the residual results. These include root mean square error (RMSE), paired t-test, Wilcoxon signed-rank test and the Cohen’s d effect size measure. RMSE evaluation is based on the mean difference between model estimates and observed values. The correlations in the model results is investigated based on paired t-test. Wilcoxon signed-rank test assesses the statistical significance of the model’s paired differences. To estimate the effect size of the performance differences, Cohen’s d measures are computed. Further, the residuals of the estimated parameters are plotted according to their respective control points. The inference results of these tests generally show that Badekas transformation approach is more precise than Bursa-Wolf. Specifically, Badekas combined case is the most precise, followed by its observation case, then Bursa-Wolf combined and finally its observation case is the least performing model. The application of various data analysis and statistical verifications make the task of data interpretation and best model selection easier.

ABSTRACT: Modification of threshold exemption from import duties was tested whether changing consumer preferences in shopping from abroad. This study uses a paired test with the initial hypothesis that there is no difference in the daily average value of imports before and after the policy is applied. The research data is only from the Customs offices which have services for shipment items (32 offices) on October 1, 2019, to March 2, 2020. Descriptive statistical results show that the average was USD135,065, then dropped to USD127,430. Based on the results, both the Paired Sample T Test and The Wilcoxon Signed Rank Test obtained a p-value of 0,000, meaning that the initial hypothesis was rejected. The adoption of this policy has changed the preferences of consumers shopping from abroad. The Government's aim to reduce the trade balance deficit and protect domestic businesses appears to be successful, however, if there are no substitute goods available in the country, the import will only move from importing consignment goods to general imports. The novelty is the variable of import duty on shopping preferences is not widely used. The limitation of this study only measures changes in spending preferences, do not in state revenue.Keywords: shopping preference, consignment, tax exemption, difference test ABSTRAK:Perubahan kebijakan batas pembebasan terhadap bea masuk dan pajak atas impor barang kiriman diuji apakah merubah preferensi konsumen dalam berbelanja barang yang dikirim langsung dari luar negeri melalui mekanisme impor barang kiriman. Penelitian ini menggunakan metode kuantitatif melalui uji berpasangan dengan hipotesis awal tidak adanya perbedaan nilai rerata impor harian baik sebelum maupun setelah kebijakan berlaku. Data penelitian hanya kantor-kantor Bea Cukai yang memiliki pelayanan atas barang kiriman (32 kantor) pada 1 Oktober 2019 sampai dengan 2 Maret 2020. Hasil statistik deskriptif menunjukkan bahwa rerata harian impor sebelum kebijakan tersebut berlaku sebesar USD135.065, kemudian turun menjadi USD127.430. Berdasarkan pengujian, baik pada Paired Sampel T Test maupun pada Wilcoxon Signed Rank Test diperoleh nilai p sebesar 0.000 (hipotesis awal ditolak). Hal ini berarti penerapan kebijakan tersebut telah merubah preferensi belanja dari luar negeri melalui impor barang kiriman. Tujuan Pemerintah untuk mengurangi defisit neraca perdagangan dan melindungi usaha dalam negeri tampaknya berhasil, namun apabila belum tersedia barang subtitusi di dalam negeri, importasi tersebut hanya akan berpindah dari impor barang kiriman menjadi impor umum. Keterbaruan pada penelitian ini adalah variabel bea masuk pada preferensi belanja belum banyak digunakan. Keterbatasan penelitian ini hanya mengukur perubahan preferensi belanja, tidak mengukur perubahan penerimaan negara.Kata Kunci: preferensi belanja, impor barang kiriman, pembebasan pajak, uji beda

Prevalensi diabetes melitus yang semakin meningkat setiap tahunnya cenderung meningkatkan risiko komplikasi dan kematian akibat diabetes melitus itu sendiri. Tujuan penelitian ini adalah untuk mengetahui pengaruh edukasi perubahan gaya hidup sehat terhadap clinical outcome (parameter klinis) pada pasien di Rumah Diabetes Universitas Surabaya. Rancangan penelitian menggunakan one group pretest-posttest yang diikuti oleh 27 subjek diabetes melitus di Rumah Diabetes Universitas Surabaya. Seluruh subjek diberikan edukasi (intervensi) dengan perangkat piring sehat dengan durasi 4 minggu. Pengukuran clinical outcome dilakukan terhadap gula darah puasa, indeks massa tubuh (IMT), lingkar perut, dan tekanan darah. Uji statistika yang digunakan adalah Wilcoxon signed rank test dan paired t-test. Hasil penelitian menunjukkan bahwa edukasi perubahan gaya hidup sehat berpengaruh signifikan terhadap penurunan gula darah puasa (p<0,001), indeks massa tubuh (p=0,005), lingkar perut (p=0,005), tekanan darah sistolik (p=0,013), namun tidak signifikan terhadap tekanan darah diastolik (p=0,247). Dapat disimpulkan bahwa edukasi perubahan gaya hidup sehat berpengaruh terhadap gula darah puasa, indeks massa tubuh, lingkar perut, dan tekanan darah sistolik. Keterbatasan dalam penelitian ini adalah keikutsertaan penderita diabetes melitus yang sedikit serta tidak adanya kelompok kontrol sebagai pembanding.
