Published: September 2023

Panel data is commonly used for the numerical response variables, while the literature for forecasting categorical variables on the panel data structure is still challenging to find. Forecasting is important because it is helpful for government policies. This study aimed to forecast multiclass or categorical variables on the panel data structure. The proposed forecasting models were autoregressive multinomial logit and autoregressive C5.0. The strategy applied so that the two models could be used for forecasting was to add autoregressive effects and fixed predictor variables such as location, time, strata, and month of observations. The autoregressive effect was assumed to be a fixed effect and treated as a dummy variable. The data used was the category of land conditions through The Area Sampling Frame (ASF) survey conducted by the BPS-Statistics Indonesia. The evaluation of both models was based on classification and forecasting performance. Classification performance was obtained by dividing the dataset into 75% training data for modeling and 25% test data for validation and then repeated 200 times. The classification results showed that the autoregressive C5.0 accuracy was 86.48%, while the autoregressive multinomial logit was 83.97%. A comparison of forecasting performance was obtained by dividing the data into training and testing based on the time sequence. The result showed that the forecasting performance was worse than the classification performance. Autoregressive C5.0 had an accuracy of 77.43%, while autoregressive multinomial logit had 77.77%.

Numerous nickel-titanium alloys have been designed by manufacturers, however there is little information on the precision of integrated EAL when utilized with various NiTi thermal processes to determine working length.An integrated EAL and endomotor assembly is utilized in this study to assess ex vivo the effects of different thermal processes on NiTi instruments.This study used 20 extracted human maxillary incisors. The visual approach was used to establish the working length (WL) control. WL was measured during cleaning and shaping using rotary files consisting of the Reciproc, Reciproc Blue, Wave One Gold, Twisted File Adaptive, and Hyflex CM systems using 0.25 diameter instrument size.Fisher's exact test and the Kruskal-Wallis statistic tests were used in the analysis of the information at hand.Heat treatment of NiTi rotary instruments has no significant impact on the EAL's accuracy (P &#62; 0.051).The precision of WL estimation using an EAL incorporated with the endomotor was unaffected by the use of thermal processes.

Published: September 2023

Diaphyseal fractures of humerus are common, representing 3% of all fractures and 20% of all humerus fractures. Though compression plate osteosynthesis is the gold standard, interlocking intramedullary nailing is also a reliable option. In this present study we evaluated the functional outcome of diaphyseal fractures of humerus treated with interlocking nails. A total of 36 patients with diaphyseal fractures of humerus, selected between October 2020 to May 2021 were managed by closed interlocking nail of humerus. This was a prospective study and all patients were followed up to a minimum of 6 months. The primary outcome measures were functional outcome assessed using DASH Score (The Disabilities of the Arm, Shoulder & Hand Score) & Constant-Murley scoring system respectively. Secondary outcomes were intra-operative conditions such as operative time and blood loss and post-operative complications. The mean time of radiological union was 15.7 weeks ranging from 14-26 weeks. All 36 fractures were united including one delayed union which united at 26 weeks. In our series, 4 patients had post operative shoulder stiffness including one prominent nail, 1 patient developed radial nerve neuropraxia which recovered in 8 weeks. All patients were evaluated on the basis of Constant Murley score for shoulder function and DASH score. In our study of 36 patients 69.4% got excellent results, 19.4% got good results, 8.3% got moderate/fair results and 2.8% got poor results. Interlocking nailing is a relatively quick, minimally invasive, biomechanically sound, cosmetically better method of internal stabilization of shaft humerus fractures with less union time, less infection and lesser threat to radial nerve and other complications. Besides it allows early mobilization. With correct anatomical knowledge, preoperative planning, good surgical techniques and postoperative rehabilitation interlocking humeral nailing is a viable option in the management of fracture shaft humerus promising excellent outcome.

Learning Habits and Speech Intelligibility of EFL Learners
Authors: Irawan Lalu Ari 
Published: September 2023

The idea of intelligibility is essential within a conversation. The status of English as a global language and its emergence varieties, the notion of standard English (British and American) may no longer appropriate within the context of global communication. This leads to the importance of teaching learners to achieve intelligibility, which is more realistic and attainable rather than forcing the students to have native like proficiency. This study aimed to examine various learning habits that may affect the quality of intelligibility of EFL learners in an English Community namely GEC in Mandalika University of Education. Qualitative narrative research approach was used. The data were collected by using two instruments:(1) indirect observation by the of a native speaker acted as a rater; (2) face to face interview which aim to find out students’ strategies in improving their pronunciation. The subjects of the study were five members of GEC who met a set of criteria. Among the five students, two performed well in aspects like word stress, segmental pronunciation, and voice quality, and these high achievers showed active improvement in both receptive and productive English skills, while the predominant issue observed among these students stems from a lack of established learning habits that facilitate consistent practice, particularly in developing productive language skills, which affects their level of intelligibility in pronouncing English words

Abstract
Background

An emerging regenerative medicine for Parkinson's is cell replacement therapy with midbrain dopaminergic (mDA) progenitor cells produced from human embryonic stem cells (hESCs) or induced pluripotent stem cells (iPSCs). Although protocols are well described, the process of hESC/iPSC differentiation remains challenging. Furthermore, different clonal iPSC lines can have variable responses to the same mDA protocol conducted in the same laboratory.

Methods

One solution to address this issue is to identify secreted biomarkers that are predictive of mDA differentiation efficiency. We used candidate approaches and unbiased proteomic methods to interrogate the secretome of cells as they are converting from pluripotent cells to committed mDA progenitor cells. We used conditioned media from two laboratories with different mDA protocols (Edinburgh, Kyoto) and multiple pluripotent stem cell lines (RC17, MasterShef7, 1231A3, 404C2).

Results

We have identified a collection of secreted molecules, including TFF3, CORIN, PDGFC, SERPINF1, and NRP1, that increase in conditioned media during the early stages of mDA differentiation. The kinetics of up-regulation and abundance of secreted biomarkers exhibited unique signatures for each cell line. However, in all cases we could identify biomarker signatures as early as day 4 of mDA protocols that were predictive of mDA differentiation efficiency. We further examined the secretome of differentiating striatal and cortical neurons to discover biomarkers of non-mDA cells, which led to the identification of PLAU and NCAM1 as diagnostic markers that should remain low during mDA differentiation. Finally, we multiplexed selected positive and negative markers to construct custom Luminex assay systems that can non-invasively analyse media samples during the time-course of mDA progenitor cell production for five hESC/iPSC lines.

Conclusion

We have identified a collection of over 10 secreted biomarkers useful for non-invasively monitoring the production of mDA progenitor cells for day 4 of differentiation from multiple clonal pluripotent stem cell lines.
