Published: April 2021

Penelitian ini merupakan penelitian dalam aspek geografi sosial. Tujuan penelitian ini adalah mengetahui pola migrasi dan faktor penyebab orang Biak bermigrasi ke Pantai Base-G Kota Jayapura. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Alasan penggunaan metode ini adalah karena teknik wawancara yang digunakan lebih banyak menggunakan wawancara mendalam terhadap informan-informan kunci termasuk penduduk setempat yang mengetahui riwayat pola migrasi dan faktor penarik orang Biak datang ke Pantai Base-G Kota Jayapura. Hasil penelitian menunjukkan bahwa migran orang Biak datang ke Jayapura karena alasan keamanan di daerah asalnya dan sebelumnya sudah ada orang Biak, yang merupakan keluarga dekat, telah menempati daerah tersebut. Alat transportasi yang pertama kali digunakan ketika datang ke Jayapura adalah kapal perintis. Alasannya karena pada saat itu belum ada kapal berukuran besar yang melayani transportasi dari Biak ke Jayapura. Migran orang Biak di Base-G baru mulai menempati Base-G tahun 1984. Sebelumnya, mereka bertempat tinggal di beberapa kawasan pemukiman penduduk di Kota Jayapura, Abepura, dan Sentani karena alasan belum mempunyai rumah. Penduduknya bertambah jumlahnya menjadi 147 jiwa. Migran orang Biak di Base-G saat ini berprofesi tetap sebagai nelayan, di samping bekerja sebagai buruh bangunan.

This article is a research in the aspect of social geography. The purpose of this study was to determine the migration patterns and factors that attract the Biak people to migrate to Base-G Beach of Jayapura City. The method used is descriptive qualitative. The reason for using this method is due to the interview technique used that mostly use in-depth interviews with key informants including local residents who have the knowledge of the history of migration patterns and the attracting factors of the Biak people to the Base-G Beach, Jayapura City. The results showed that Biak migrants came to Jayapura for security reasons in their home areas and previously there were Biak people, who were close relatives, who had occupied the area. The first means of transportation used when they came to Jayapura were pioneer ships. The reason was because at that time there were no large ships serving transportation from Biak to Jayapura. Biak migrants at Base-G only started to occupy Base-G in 1984. Previously, they lived in several residential areas in Jayapura, Abepura, and Sentani cities because they did not have a house. The population has increased to 147 inhabitants. Biak migrants at Base-G currently work as fishermen, in addition to working as construction workers.

Salah satu persoalan fundamental yang dihadapi pembangunan pertanian di wilayah perbatasan Indonesia adalah peran masing-masing lembaga terkait dengan pembangunan pertanian belum terpetakan dengan jelas menyebabkan pembangunan menjadi ego-sektoral. Penelitian ini menganalisis keterkaitan peran antar lembaga dalam pembangunan pertanian di perbatasan dengan Metode Interpretative Structural Modeling (ISM) dan berlokasi di tiga provinsi perbatasan dengan negara lain, yaitu: (1) Kalimatan Utara-Malaysia, (2) Papua-Papua Nugini, dan (3) Nusa Tenggara Timur-Timor Leste. Hasil penelitian menunjukkan bahwa, pertama, dari sisi keterkaitan peran antar lembaga pemeran yang beroperasi dalam pembangunan pertanian, ditemukan bahwa salah satu aspek penentu penguatan kelembagaan pertanian di perbatasan adalah fungsi koordinasi antar lembaga (interkoneksitas). Kedua, lembaga-lembaga pemeran prioritas terdistribusi ke dalam sektor independent dan linkage (koefisien rata-rata DP = 0,79) dan dependent (D=0,37) yaitu: (1) Kementerian Desa dan Pembangunan Daerah Tertinggal & Transmigrasi, (2) Kementerian Kelautan dan Perikanan, (3) Kementerian Pertanian/Ditjen Perkebunan, (4) Kementerian Perindustrian dan Perdagangan, (5) Kementerian Kelautan dan Perikanan. (6) Badan Pemberdayaan Masyarakat Desa (BPMD) provinsi/kabupaten, (7) Dinas Perindustrian & Perdagangan (Provinsi), (8) Dinas Kelautan dan Perikanan (provinsi/kabupaten), (9) Dinas Perhubungan (Provinsi/Kabupaten) (10) Dinas Pertanian/perkebunan (Provinsi/Kabupaten), (11) Lembaga Pemasaran/Koperasi Pertanian, (12) Lembaga Perbankan, (13) Dinas Koperasi/UKM (Kabupaten), (14) Kelompok Tani/Gabungan Kelompok Tani (Gapoktan), dan (15) Badan Penyuluhan Pertanian/Perkebunan (Kabupaten). Empat lembaga di antaranya merupakan lembaga pemeran kunci, yaitu: (1) Dinas Pertanian/Perkebunan (Provinsi/Kabupaten), (2) Badan Penyuluhan Pertanian/Perkebunan (Kabupaten), dan (3) Kelompok Tani/Gabungan Kelompok Tani (Gapoktan). Jika dipilah berdasarlkan tingkatannya, maka lembaga tingkat pusat yang memiliki peranan sangat penting dalam penguatan kelembagaan pertanian di perbatasan yaitu: (1) Kementerian Pertanian/Ditjen Perkebunan, (2) Pusat Penelitian Pertanian/Perkebunan (Balitbang Pertanian), dan (3) Kementerian Desa, Pembangunan Daerah Tertinggal dan Transmigrasi.
Hermeneutics and Phenomenology in Human and Social Sciences Research
Authors: Pérez-Vargas John Jairo , Nieto-Bravo Johan Andrés , Santamaría-Rodríguez Juan Esteban 
Published: April 2021

This article of reflection problematizes the relationships between phenomenology and hermeneutics as epistemic places of research work through a documentary approach built in two phases. First, the text reflects on the terminological use present in the paradigms, approaches, epistemological perspectives, and research methods, thereby identifying that there is no criteria univocity in its references and approaches about research methodology treaties. Likewise, it is evident that there are methodological proposals that include phenomenology and hermeneutics in a complementary, articulated, or isolated way without allowing precise places of understanding that allow to locate their application in research. Based on the aforementioned, the second phase proposes an individual approach to the background and comprehensions of phenomenology and hermeneutics, identifying particularities that characterize them, possible theoretical-practical differences and approaches that can be established in view of their relevance from the epistemic and methodological framework of research in human and social sciences.

Relativistic Frozen Density Embedding calculations of solvent effects on the NMR shielding constants of transition metal nuclei.
Authors: Olejniczak Malgorzata , Antušek Andrej , Jaszunski Michal 
Published: April 2021

Nuclear Magnetic Resonance (NMR) shielding constants
of transition metals in solvated complexes
are computed at the
relativistic density functional theory (DFT) level. The solvent effects evaluated with subsystem-DFT
approaches are compared with the
reference
solvent shifts predicted from supermolecular calculations.
Two subsystem-DFT approaches are analyzed – in the
standard
frozen density embedding (FDE) scheme the transition metal complexes are embedded in an environment of solvent molecules whose density is kept frozen, in the second approach the
densities of the complex and of its environment are relaxed in the “freeze-and-thaw”
procedure.
The latter approach
improves the description of the solvent effects in most cases, nevertheless the FDE deficiencies are rather large in some cases.
Keywords — Frozen Density Embedding, NMR shielding constant, solvent shifts, transition-metal complexes
Does Alt-RAMEC protocol and facemask treatment affect dentoalveolar structures?
Authors: Özbilen Elvan Önem , Yılmaz Hanife Nuray , Acar Yasemin Bahar 
Published: April 2021

ABSTRACT

Objectives
To evaluate dentoalveolar changes immediately after the alternate rapid maxillary expansion and constriction (Alt-RAMEC) protocol and facemask (FM) treatment using cone-beam computed tomography images.

Materials and Methods
Cone-beam computed tomography images of 20 patients (mean age = 9.64 ± 1.3 years) who received the Alt-RAMEC protocol before FM treatment were retrieved in this retrospective study. Dental and alveolar inclinations, buccal and palatal alveolar bone thickness, and buccal and palatal alveolar bone height changes were measured before treatment (T0), after the Alt-RAMEC protocol (T1), and after FM treatment (T2). Measurements for right and left molars were performed separately. The Shapiro-Wilks test was used to assess the conformity of the parameters to the normal distribution. The paired t-test and repeated measures analysis of variance were used for normally distributed data. The Wilcoxon signed-rank test and Friedman test were used for non-normally distributed data. The Bonferroni correction was used to reduce the chances of obtaining false-positive results. Statistical significance was set at P &lt; .05.

Results
Buccal alveolar bone thickness and alveolar bone inclinations decreased significantly from T1 to T0 and showed no significant change from T2 to T1. The total reduction T2-T0 was statistically significant. The change in palatal alveolar bone thickness was not significant T1-T0 but increased significantly for T2-T1 and T2-T0. Buccal alveolar bone height, palatal alveolar bone height, and molar inclinations increased significantly T1-T0, but there was no significant change T2-T1. The total reduction at T2-T0 was statistically significant.

Conclusions
The results of this study revealed that the effects of the Alt-RAMEC protocol on dentoalveolar tissues were similar to the changes reported in the literature after rapid palatal expansion.

Published: April 2021

In this paper, the education programs offered to students with special needs in the online distance education format during the Covid-19 pandemic period in TRNC and the online family guidance/counseling services offered to their families were evaluated from the perspective of the families. In the study, the data obtained follow a parallel course with other studies in the literature. In studies on the academic support provided by families for children and family participation in learning processes, the relation between family involvement at home and at school and academic success was revealed, which is also the case in this study. In addition, family involvement was determined as an essential predictor of the school success of students, and it was emphasized that increasing family participation would help education reach higher standards and students encounter alternative opportunities.
Analysis of colon curvatures toward optimizing colonoscopy examinations
Authors: Laframboise Jacob , Barr Keiran , Ungi Tamas , Tan Pearl , Hookey Lawrence 
Published: April 2021

Purpose: Colonoscopy is a complex procedure with considerable variation among patients, requiring years of experience to become proficient. Understanding the curvature of colons could enable practitioners to be more effective. The purpose of this research is to develop methods to analyze the curvature of patients’ colons, and compare key segments of colons between supine and prone positions.
Methods: The colon lumen in CT scans of 42 patients were segmented. The following steps were automated by Python scripts in the 3D Slicer application: a set of center points along the colon were generated, and a curve was fit to those points. By identifying local maximums and local minimums in curvature, curves were defined between two local curvature minimums. The angle of each curve was calculated over the distance of curves.
Results: This process was used to identify and analyze curves on the colon centerline in different patient positions. On average, there are 32.63±0.83 curves in supine position and 31.24±0.80 in prone. In the supine position the curves turn an average of 77.80±2.25 degrees, and 75.88±1.87 degrees in prone. Graphically, there are observable differences between positions for curves of specific magnitudes.
Conclusion: This process can quantify the curvature of colons, and could be adapted to consider other patient groups. Descriptive statistics indicate supine position has more curves in the descending colon, and prone has sharper curves in the descending colon. These preliminary results motivate further work with a larger sample size for statistical analysis, which may reveal significant differences.
Using Convolutional Neural Networks for the Detection of Spinal Transverse Processes
Authors: Wu Victoria 
Published: April 2021

Introduction: Scoliosis, an excessive curvature of the spine, affects approximately 1 in 1,000 individuals. As a result, there have formerly been implementations of mandatory scoliosis screening procedures. Screening programs are no longer widely used as the harms often outweigh the benefits; it causes many adolescents to undergo frequent diagnosis X-ray procedure This makes spinal ultrasounds an ideal substitute for scoliosis screening in patients, as it does not expose them to those levels of radiation.
Spinal curvatures can be accurately computed from the location of spinal transverse processes, by measuring the vertebral angle from a reference line [1]. However, ultrasound images are less clear than x-ray images, making it difficult to identify the spinal processes. To overcome this, we employ deep learning using a convolutional neural network, which is a powerful tool for computer vision and image classification [2].
Method: A total of 2,752 ultrasound images were recorded from a spine phantom to train a convolutional neural network. Subsequently, we took another recording of 747 images to be used for testing. All the ultrasound images from the scans were then segmented manually, using the 3D Slicer (www.slicer.org) software. Next, the dataset was fed through a convolutional neural network. The network used was a modified version of GoogLeNet (Inception v1), with 2 linearly stacked inception models. This network was chosen because it provided a balance between accurate performance, and time efficient computations.
Results: Deep learning classification using the Inception model achieved an accuracy of 84% for the phantom scan.
Conclusion: The classification model performs with considerable accuracy. Better accuracy needs to be achieved, possibly with more available data and improvements in the classification model.

Authors: Rattanakaemakorn Ploysyne , Ploydaeng Monthanat , Udompanich Siriorn , Thadanipon Kunlawat , Rutnin Suthinee , Rajatanavin Natta 
Published: April 2021

Background:
Mycosis fungoides is the most common form of cutaneous T-cell lymphoma. Narrowband ultraviolet B and psoralen and ultraviolet A are effective treatment options, but studies of their treatment efficacy and disease relapse remain limited.

Objectives:
This study aimed (1) to determine the efficacy of narrowband ultraviolet B and psoralen and ultraviolet A as a treatment for early-stage mycosis fungoides and explore the predictive factors for complete remission and (2) to determine the relapse rate and analyze their predictive factors, including the utility of maintenance therapy.

Methods:
This was a retrospective cohort study consisting of 61 patients with early-stage mycosis fungoides (IA - IB) treated with narrowband ultraviolet B or psoralen and ultraviolet A as the first-line therapy from January 2002 to December 2018 at the Division of Dermatology, Ramathibodi Hospital, Bangkok, Thailand. Cox regression analysis and Kaplan–Meier survival curve were performed for the main outcomes.

Results:
A complete remission was achieved by 57 (93.5%) patients. The median time to remission was 7.80 ± 0.27 months. Types of phototherapy (narrowband ultraviolet B or psoralen and ultraviolet A), age and gender did not associate with time to remission, while the presence of poikiloderma and higher disease stage led to a longer time to remission. The cumulative incidence of relapse was 50.8%. The median time to relapse was 24.78 ± 5.48 months. In patients receiving phototherapy during the maintenance period, a treatment duration longer than six months was associated with a significantly longer relapse-free interval.

Conclusion:
Narrow-band-ultraviolet B and psoralen and ultraviolet A are effective treatment options for early-stage mycosis fungoides. Maintenance treatment by phototherapy for at least six months seems to prolong remission.
Comparison of effectiveness of interventions in reducing mortality in patients of toxic epidermal necrolysis: A network meta-analysis
Authors: Patel Tejas K. , Patel Parvati B. , Thakkar Sejal 
Published: April 2021

Background:Limited evidence is available about effectiveness and choice of immunomodulating treatment modalities for toxic epidermal necrolysis (TEN).Aims:To compare the effectiveness of interventions to reduce mortality in patients of toxic epidermal necrolysis through network meta-analysis.Methods:Studies were retrieved using PubMed, Google Scholar and Cochrane Database of Systematic Reviews from inception to September 18, 2018. Only English language articles were considered. Observational and randomized controlled studies having ≥ 5 TEN patients in each intervention arm were included. Two investigators independently extracted study characteristics, intervention details and mortality data. Bayesian network meta-analysis was performed using the Markov chain Monte Carlo (MCMC) approach through the random effect model. The ranking analysis was done to provide a hierarchy of interventions. The consistency between direct and indirect evidence was assessed through node spit analysis. The primary outcome was to compare the mortality [Odds ratio OR (95% credibility interval CrI)] among all treatment modalities of TEN.Results:Twenty-four studies satisfying the selection criteria were included. The network analysis showed improved survival with cyclosporine as compared to supportive care [OR- 0.19 (95% CrI: 0.05, 0.59)] and intravenous immunoglobulin [OR- 0.21 (95% CrI: 0.05, 0.76)]. The hierarchy of treatments based on “surface under the cumulative ranking curves” (SUCRA) value were cyclosporine (0.93), steroid+intravenous immunoglobulin (0.76), etanercept (0.59), steroids (0.46), intravenous immunoglobulin (0.40), supportive care (0.34) and thalidomide (0.02). No inconsistencies between direct and indirect estimates were observed for any of the treatment pairs.Limitations:Evidence is mainly based on retrospective studies.Conclusion:The use of cyclosporine can reduce mortality in TEN patients. Other promising immunomodulators could be steroid+intravenous immunoglobulin combination and etanercept.
Accurate Tunneling Splittings for Proton Transfer in Malonaldehyde and Formic Acid Dimer Using the One-Dimensional Schrödinger Equation
Authors: Tikhonov Denis 
Published: April 2021

In this manuscript we present an approach for computing tunneling splittings for large amplitude motions. The core of the approach is a solution of an effective one-dimensional Schrödinger equation with an effective mass and an effective potential energy surface composed of electronic and harmonic zero-point vibrational energies of small amplitude motions in the molecule.The method has been shown to work in cases of three model motions: nitrogen inversion in ammonia, single proton transfer in malonaldehyde, and double proton transfer in the formic acid dimer. In the current work we also investigate the performance of different DFT and post-Hartree-Fock methods for prediction of the proton transfer tunneling splittings, quality of the effective Schrödinger equation parameters upon the isotopic substitution, and possibility of a complete basis set (CBS) extrapolation for the resulting tunneling splittings.
