Authors: Fadillah Haris
Published: May 2021

Artikel ini merupakan versi kedua dari PUPUR DINGIN SEBAGAI PERAWATAN WAJAH KHAS MASYARAKAT BANJAR yang berisikan materi tentang “Pupur dingin” atau bedak dingin merupakan perawatan wajah tradisional yang berbasis kearifan lokal Kalimantan Selatan yang telah digunakan oleh wanita Kalimantan sejak dahulu. Selain fungsinya sebagai perawatan kulit (skin care) dari sengatan matahari, selain itu pupur dingin juga banyak diminati sebagai oleh-oleh khas Banjar Kalimantan Selatan. Pengrajin bedak dingin di kelurahan Pasayangan Kabupaten Banjar, masih bertahan untuk dapat memproduksi juga disebabkan karena ingin mempertahankan tradisi warisan dari orang terdahulu. Melihat potensi dari bedak dingin yang tidak hanya diminati masyarakat lokal tetapi juga diminati oleh masyarakat dari luar daerah berpotensi untuk dapat dikembangkan. Namun produksi bedak dingin apabila musim hujan tidak bisa dilakukan karena proses pengering sangat tergantung dengan sinar matahari. Pupur dingin digunakan untuk melindungi kulit selama bekerja di ladang di bawah terik matahari
THE EFFECT OF SINGLE NUCLEOTIDE POLYMORPHISM (SNP) IN GLIOBLASTOMA MULTIFORME
Authors: Ghosh Asmita , Mukherjee Dattatreya , Patel Parth , Mukhopadhyay Debraj
Published: May 2021

Single nucleotide polymorphism is a genetic substitution of a base pair at a single position of the genome. SNPs are a common phenomenon and influence mRNA expression. Half of the SNPs occur in the non-coding region with 25% being mis-sense mutation and 25% being silent mutations. SNPs belong to the last generation of molecular markers which is identified through SNP mapping. SNPs are extensively studied to distinguish genetic expression and protein synthesis. These genetic differences are a major source of diseases in humans like cancers. One of the most common types of cancer of the brain is the Glioblastoma Multiforme that accounts for more than 80% of the malignant primary brain tumors (PBT). Researchers have found out a potential role of various SNPs in the genome to have a strong relation with Glioma formation and proliferation. Most SNPs are either not discovered, or their biological mechanisms are unknown, making it difficult to link putative associations with disease onset. The given review aims to identify some of the most common SNPs associated with GBM and classify the genetic basis along with future prospects. These SNPs are pioneer in Genome Wide Association studies to help in cancer research and identification of specific genetic alterations liked to GBM. Single Nucleotide Polymorphisms in a gene can be used as genetic biomarkers to aid better understanding of the mechanism of cancer formation, its aetiology, progression and metastatic behaviour.

Self-Reflection, Insight, and Mood Disorder Symptoms: Evaluating the Short Form of the Self-Reflection and Insight Scale with Clinical Interviews and Self-Reports
Authors: Silvia Paul , Eddington Kari , Harper Kelly , Kwapil Thomas Richard
Published: May 2021

The 20-item Self-reflection and Insight Scale (SRIS) is a widely used measure of individual differences in self-focused attention and private self-consciousness. In the present research, we examined the validity of a 12-item short form of the SRIS, which was recently developed based on item response theory models. Measures related to mental health and well-being were used as criteria for evaluating the relative effect sizes for the long and short SRIS. In Study 1 (n = 278 adults), the short and long SRIS scores had highly similar correlations with dimensional measures of depression, anxiety, and stress symptoms as well as with neuroticism. In Study 2 (n = 78 adults), participants were classified into major depression and healthy control groups based on structured clinical interviews. The short and long SRIS had similar profiles of differences between the two groups. Taken together, the studies suggest that the short forms effectively recover the effect sizes of the long forms, so the briefer SRIS would be a good option when time and survey space are tight.
Living in the Big Pond: Adding the Neighborhood as a Frame-of-Reference for Academic Self-Concept Formation
Authors: Fleischmann Moritz , Becker Dominick , Weßling Katarina , Nagengast Benjamin , Trautwein Ulrich
Published: May 2021

Research on the big fish little pond effect (BFLPE) shows that classroom selectivity, in terms of class-average achievement, negatively affects students’ academic self-concept due to social comparison processes. The neighborhood effects literature reports positive effects of neighborhood selectivity, in terms of advantageous socioeconomic neighborhood conditions, on students’ academic development via collective socialization mechanisms, but has not investigated academic self-concept as an outcome. To investigate how socioeconomic neighborhood conditions affect academic self-concept, we separately and simultaneously analyzed the effects of classroom and neighborhood selectivity on students’ academic self-concept using two student samples coming from two grade levels (N Grade 5) = 3,906, N Grade 9) = 3,277). When separately analyzing the neighborhood, we found socioeconomic neighborhood conditions to negatively predict general, math, and German self-concept in Grade 5. In Grade 9 this was only the case for math self-concept. When simultaneously analyzing the classroom and the neighborhood, we found advantageous neighborhood conditions to negatively predict general and math self-concept only in Grade 5. Our study shows that negative neighborhood effects on academic self-concept may exist, thereby introducing the neighborhood as a potential frame-of-reference for academic self-concept formation.
Association between Work Experience and Work-Related Musculoskeletal Disorders among the Clinical and Teaching Physiotherapists of Gujarat, India – An Observational Study
Authors: Ramanandi Vivek Harsukhbhai
Published: May 2021

Introduction: Work-related musculoskeletal disorders (MSDs) are present universally where physiotherapists are found to be at higher risk of being affected due to the postures attained at work. This can lead to excessive exertion associated with significant discomfort and pain in loading joints. In addition to these, the anatomical, physiological and physical characteristics of males and females are disparate so gender-based differences may also affect. However, the paucity of data for correlating the years of experience with MSDs was found in Gujarat. Hence, the present study was undertaken to investigate the association between the prevalence of MSDs with an increase in work experience among the physiotherapists of Gujarat.

Methods: This was an online cross-sectional survey study where 322 physiotherapists were included after gaining informed electronic consent. Prevalence rates were found by employing a standardized Nordic Musculoskeletal Questionnaire (NMQ) and non - parametric tests were used for data analysis.

Results: Present study showed no statistically significant relationship between the increase in work experience and work-related MSDs prevalence. It was also observed that females (68.63%) have more prevalence compare to males (61.19%). The majority f the physiotherapists reported complaints of MSDs in the lower back (41.30%) and neck (37.58%) regions.

Conclusion: It is inferred that the chances of being affected by MSDs do not increase with years of work experience. Moreover, female physiotherapists are more prone to MSDs. Thus, early identification and interventions through ergonomic advice and physiotherapy can prove to be very effective in declining the rate of MSDs to a notable extent.

Bilateral intracranial subdural osteomas of varying sizes imaged 7 years apart: illustrative case
Authors: Laghari Fahad J. , Eakin Sarah , El-Zuway Salem
Published: May 2021

BACKGROUND

Previously, solitary and unilateral aggregates of intracranial subdural osteomas have been described. These tumors are thought to be slow growing and at times inconsequential on the basis of characteristics of subjacent brain. Unilateral location and history of traumas have led to the thought that the head trauma may play a role in pathogenesis.

OBSERVATIONS

The authors describe a unique case of a patient who was found to have bilateral intracranial subdural osteomas of unequal size on the basis of computed tomography and magnetic resonance imaging. The presenting symptom was headache. Initially small and thought to be irrelevant, these tumors grew over the course of 7 years to cause mass effect and effacement of the sulci and gyri. The larger 15-cm-long tumor was excised and was sent for pathology, which showed classic histology for subdural osteoma.

LESSONS

The described case uniquely demonstrates evidence of the slow growth of intracranial subdural osteomas over the course of years. It is crucial not to disregard the tumor because it can grow over time to cause mass effect. Patient follow-up is strongly recommended. Bilateral tumor occurrence at a similar location in this case supports an etiology other than trauma. Further research is necessary.
Chiari malformation type 1: are we doing less with more? Illustrative case
Authors: Talamonti Giuseppe , Ferrari Erika , D’Aliberti Giuseppe
Published: May 2021

BACKGROUND

Classic treatment of Chiari malformation type 1 consists of foramen magnum decompression. Selected patients may require occipitocervical fixation, transoral odontoidectomy, tonsillectomy, and so forth. Treatment standardization does not yet exist, and some patients risk being overtreated.

OBSERVATIONS

A 20-year-old man with headache and Chiari malformation type 1 underwent extradural bone decompression. One year later, he was managed with the extradural section of his filum terminale. Eighteen months later, the patient underwent monitoring of intracranial pressure, occipitocervical stabilization, transoral odontoidectomy, minimally invasive subpial tonsillectomy, and occipital cranioplasty. His headache never changed, and he progressively developed hemiparesis and swallowing and respiratory disturbances. Two years later, a new magnetic resonance imaging scan showed extended syringomyelia with scarce peritonsillar subarachnoid space. The umpteenth operation consisted of the removal of a constricting epidural scar, arachnoid dissection, total tonsillectomy, creation of a wide subarachnoid space, and dural sac augmentation. The patient’s initial postoperative course was smooth, and his headache improved. However, 8 days after surgery, the patient acutely presented with vegetative disturbances and died because of malignant brainstem edema of unknown origin.

LESSONS

The story of this patient is not so uncommon. He underwent all the possible surgical treatments rather than a timely adequate osteodural decompression. Probably, he received less with more.
Herpes simplex meningitis after vestibular schwannoma surgery: illustrative case
Authors: Trakolis Leonidas , Naros Georgios , Vougioukas Vassilios , Tatagiba Marcos
Published: May 2021

BACKGROUND

Herpes is the most common cause of viral encephalitis in the young population. Herpes meningitis following brain surgery is very rare, however. Only a few cases are reported in the literature, and only one concerned an infection after vestibular schwannoma surgery.

OBSERVATIONS

The authors report a case of a 44-year-old patient who developed severe herpes meningitis a few days after removal of a large cystic vestibular schwannoma.

LESSONS

Herpes simplex virus meningitis following a posterior fossa surgery must be considered when patients develop atypical symptoms a few days after surgery.
Misdiagnosis of elevation of β-hCG in cystic craniopharyngioma: illustrative case
Authors: Saleh Umaira , Lim Liang Hooi , Ismail Ihfaz , Abd Wahab Nasser
Published: May 2021

BACKGROUND

Craniopharyngiomas and germ cell tumors (GCTs) are both rare intracranial tumors commonly present in childhood or middle age. They share similar clinical and radiological features. GCTs commonly give rise to tumor markers in the cerebrospinal fluid, hence guiding the treatment plan.

OBSERVATIONS

This article reports the case of a 5-year-old boy with a large sellar and suprasellar mass with obstructive hydrocephalus. Laboratory studies showed increased beta-human chorionic gonadotrophin (β-hCG) levels in the cystic fluid, suggestive of choriocarcinoma. He underwent 3 cycles of chemotherapy but showed a poor response. Further aspiration followed by tumor debulking was performed, and histopathological examination revealed craniopharyngioma.

LESSONS

This case report indicates that β-hCG, commonly regarded as a specific tumor marker for choriocarcinoma, is detectable in other forms of suprasellar tumors. The authors highlight clinical and radiological features of suprasellar tumors that can be misdiagnosed as intracranial GCTs. The relevance of tumor markers and indications for histopathological confirmation are discussed.

Authors: Nozawa Takanori , Okamoto Kouichirou , Nakazato Shinji , Motohashi Kunio , Suzuki Tomoaki , Morita Kotaro , Tashi Hideki , Watanabe Kei , Hasegawa Hitoshi , Watanabe Masato , Kawashima Hiroyuki , Fujii Yukihiko
Published: May 2021

BACKGROUND

Bow hunter’s syndrome or stroke (BHS) is characterized by rotational vertebrobasilar insufficiency elicited by rotation of the neck. It is caused by dynamic and reversible occlusion of the vertebral artery (VA). Reversible symptoms of rotational vertebrobasilar insufficiency are described as bow hunter’s syndrome, although brain infarction is rarely reported as bow hunter’s stroke.

OBSERVATIONS

A 70-year-old man experienced repeated cerebellar infarctions three times in the posterior inferior cerebellar artery (PICA) distribution of the nondominant right VA connecting the basilar artery. The onset of symptoms indicating cerebellar infarcts and the patient’s head position changes were unrelated. Dynamic digital angiography (DA) revealed that the nondominant right VA was occluded by an osteophyte from the C4 vertebral body, and the right PICA branches were shown to be passing through the distal right VA from the left VA. These findings were observed when the patient’s head was tilted to the right. An arterio-arterial embolic mechanism was suggested as the cause of repeated cerebellar infarctions.

LESSONS

Transient nondominant VA occlusion has been rarely reported as a cause of BHS when the head is tilted. To confirm the diagnosis of BHS, additional head tilt is recommended when performing dynamic DA in patients with a cervical osteophyte.
Development and natural course of lateral posterior choroidal artery aneurysms arising from fragile choroidal collaterals in moyamoya disease: illustrative cases
Authors: Suzuki Tomoaki , Hasegawa Hitoshi , Okamoto Kouichirou , Ando Kazuhiro , Shibuya Kohei , Takahashi Haruhiko , Saito Shoji , Oishi Makoto , Fujii Yukihiko
Published: May 2021

BACKGROUND

Choroidal collaterals are a risk factor for hemorrhagic stroke, even in the nonhemorrhagic hemisphere, among patients with moyamoya disease (MMD). Peripheral choroidal aneurysms rupture in fragile collaterals; however, the development and natural course of these aneurysms remain elusive.

OBSERVATIONS

A 51-year-old woman, who had experienced a right cerebral hemorrhage 3 years earlier, presented with asymptomatic minor bleeding from a left lateral choroidal artery aneurysm in a predeveloped choroidal anastomosis. Although the aneurysm spontaneously thrombosed within 2 months, the choroidal collaterals persisted. After bypass surgery, the choroidal anastomosis regressed, and neither a de novo aneurysm nor a hemorrhagic stroke occurred. A 75-year-old woman with MMD, who had experienced a left frontal infarction 6 years earlier, experienced recurrent right intraventricular hemorrhage from a ruptured lateral choroidal artery aneurysm that developed in the choroidal anastomosis. The aneurysm spontaneously regressed 3 days after the rebleeding with no recurrence over the following 7 years.

LESSONS

Choroidal artery aneurysms may develop in the choroidal anastomosis and rupture in the nonsurgical or contralateral hemispheres. Patients with MMD who have a history of hemorrhagic or ischemic stroke and impaired cerebral blood flow require careful observation. Although aneurysms may rapidly regress spontaneously, bypass surgery can stabilize hemodynamic stress and prevent further hemorrhage.
Spontaneous closure of an incidental high-flow paravertebral arteriovenous fistula caused by vertebral giant cell tumor curettage: illustrative case
Authors: Lin Yen-Heng , Huang Yu-Cheng , Tsuang Fon-Yih
Published: May 2021

BACKGROUND

Paravertebral arteriovenous fistula (AVF) after spinal surgery is rarely reported in the literature. Its natural course is largely unknown.

OBSERVATIONS

The authors report a 31-year-old woman with a high-flow AVF after T12 vertebral giant cell tumor curettage. Eight months after the initial surgery, revision en bloc surgery was planned. Preoperative computed tomography angiography was performed for vascularity assessment, which incidentally revealed a large paravertebral early-enhanced venous sac. High-flow AVF was confirmed through subsequent spinal angiography. Endovascular embolization was scheduled before the surgery to avoid massive blood loss. However, the AVF closed spontaneously 1 month after the spinal angiography. The plan was changed to preoperative embolization; subsequently, three-level en bloc spondylectomy was performed smoothly.

LESSONS

Iatrogenic AVF is possible, prompting investigation by vascular imaging when suspected. Embolization is a preferred treatment method when feasible. However, for iatrogenic etiology, the prothrombotic property of the contrast medium may induce the resolution. Multidisciplinary discussion can be very helpful before aggressive spinal surgery.
Rare large colloid cyst obstructing the posterior third ventricle: illustrative case
Authors: Gerstl Jakob V. E. , Aquilina Kristian , Florman Jeffrey E.
Published: May 2021

BACKGROUND

Colloid cysts of the posterior third ventricle are exceedingly rare. This location is a high-risk zone for colloid cysts because of potential obstruction of the cerebral aqueduct.

OBSERVATIONS

The authors report a case of a 57-year-old man who presented with a 6-month history of progressive headache, short-term memory loss, visual blurring, and an episode of double vision. Magnetic resonance imaging (MRI) revealed a colloid cyst, 22 mm in diameter, attached to the roof of the posterior third ventricle. The posterior third ventricle was obstructed, but both foramina of Monro were patent. The entirety of the cyst was resected via a right frontal parasagittal, interhemispheric, transventricular approach through the foramen of Monro. It was not contained within the velum interpositum. The patient did not experience any postoperative deficits.

LESSONS

This case supports the theoretical evidence that colloid cysts in the posterior zone of the third ventricle pose a risk for obstructive hydrocephalus. This report of a large cyst in a rare location describes a unique lesion and provides the first published MRI description.
First reported use of real-time intraoperative computed tomography angiography image registration using the Machine-vision Image Guided Surgery system: illustrative case
Authors: Wadhwa Harsh , Malacon Karen , Medress Zachary A. , Leung Christopher , Sklar Matthew , Zygourakis Corinna C.
Published: May 2021

BACKGROUND

Vertebral artery injury is a devastating potential complication of C1–2 posterior fusion. Intraoperative navigation can reduce the risk of neurovascular complications and improve screw placement accuracy. However, the use of intraoperative computed tomography (CT) increases radiation exposure and operative time, and it is unable to image vascular structures. The Machine-vision Image Guided Surgery (MvIGS) system uses optical topographic imaging and machine vision software to rapidly register using preoperative imaging. The authors presented the first report of intraoperative navigation with MvIGS registered using a preoperative CT angiogram (CTA) during C1–2 posterior fusion.

OBSERVATIONS

MvIGS can register in seconds, minimizing operative time with no additional radiation exposure. Furthermore, surgeons can better adjust for abnormal vertebral artery anatomy and increase procedure safety.

LESSONS

CTA-guided navigation generated a three-dimensional reconstruction of cervical spine anatomy that assisted surgeons during the procedure. Although further study is needed, the use of intraoperative MvIGS may reduce the risk of vertebral artery injury during C1–2 posterior fusion.
Chronic allergic fungal sinusitis invading the skull base in an immunocompetent male: illustrative case
Authors: Naik Anant , Yang Darrion Bo-Yun , Bellafiore Frank J. , Amine Muhamad A. , Hassaneen Wael
Published: May 2021

BACKGROUND

Allergic fungal sinusitis (AFS) is an immunoglobulin E–mediated reaction to fungal organisms in the sinonasal region and can be categorized as acute or chronic. Acute infection is typical in immunocompromised patients, while chronic infection is classically seen in immunocompetent patients. Spread of infection to the skull base is a rare and potentially lethal complication of prolonged infection. Surgical management is frequently augmented with steroid therapy to prevent recurrence.

OBSERVATIONS

The authors present a case of a 20-year-old African American male with prolonged headaches and blurred vision who was diagnosed with chronic invasive fungal sinusitis resulting in invasion of fungal burden into the anterior skull base and the posterior aspect of the clivus, in addition to complete obliteration of the maxillary sinus. The patient was managed surgically without complication and with gradual improvement in vision.

LESSONS

Early management and detection of AFS should be a focus to prevent erosion of the fungal burden into the skull base. Neurosurgery and ear, nose, and throat surgery have a multidisciplinary role in the management of advanced AFS cases.

Published: May 2021

Introduction: Vitamin D deficiency is an emerging risk factor for cardiovascular diseases. Very few studies have been done to find out vitamin D deficiency status among cardiovascular patients in Nepalese setup. This research aims to find out the prevalence of vitamin D deficiency among patients of acute coronary syndrome admitted in a tertiary care center of eastern Nepal.

Methods: This was a descriptive cross-sectional study conducted among patients of acute coronary syndrome admitted in a tertiary care hospital from 1st February 2018 to 31st July 2018. Ethical clearence was taken from Institutional Review Committee of B.P. Koirala Institute of Health Sciences (Reference number: 259/074/075-IRC). Convenience sampling method was used. Data was entered in Microsoft Excel and analyzed using Statistical Package for the Social Sciences version 25. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data.

Results: A total of 33 (64.7%) at 95% Confidence Interval (51.58-77.82) patients of acute coronary syndrome had vitamin D deficiency in our study with 19 (37.3%) having mild deficiency and 14 (27.4%) having moderate deficiency. None of the patients had severe vitamin D deficiency in our study. The mean vitamin D levels were lower in diabetics (23.57Â±9.28ng/ml) as compared to non-diabetics (31.91Â±12.50ng/ml), in hypertensive patients (24.36Â±7.67ng/ml) as compared to non-hypertensive patients (30.97Â±13.72ng/ml), and in patients with dyslipidemia (22.86Â±6.44ng/ml) as compared to those without dyslipidemia (37.68Â±13.15ng/ml).

Conclusions: Prevalence of vitamin D deficiency among patients of acute coronary syndrome in our study was comparable to various other homologous international studies.

Published: May 2021

Dieng area is a mountainous area, dieng has land with high fertility levels so that they are increasingly high in the agricultural sector, especially potatoes. During the time, the technology for sorting potato seeds was still manual with humans, so it was less effective. The conveyor here is very useful as this device which will later work with loadcell as a weigher, and this device will be driven using a dc motor then the speed stabilization uses the PID algorithm with trial and error methods and this tool is supported using ultrasonic sensors and two servo sorting. This device works with 1 cycle, namely with 1 command with a value of KP 55, KI 20 and KD 0.001. The conveyor movement is quite stable with an average error value of 0.276 load cell with a standard deviation of 0.211877 with an achievement level of 80%.
Mechanical properties of bituminous mixtures under sinusoidal cyclic loadings: Experiment and modelling
Authors: Tuan Nguyen Quang
Published: May 2021

Mechanical behaviour of bituminous mixtures is characterized by the great thermal sensitivity and the large viscous effects. This paper focuses on the linear viscoelastic (LVE) behaviour of bituminous mixtures that is considered for pavement design. The studied material is a GB3 mix (GB in French is “Grave Bitume”) which is often used for base course construction in France. Complex modulus tests are performed to determine the LVE properties of bituminous mix. Sinusoidal cyclic loadings in tension and compression for small strain amplitudes (up to 10-4 m/m) are applied on cylindrical samples at different temperatures (from -23.4°C to 39.1°C) and different frequencies (from 0.03 to 10Hz). The complex modulus E* and complex Poisson’s ratio ν* are obtained for these large ranges of temperature and frequency. From all these data, it is shown that within the linear viscoelastic domain and in the 3D case, the Time Temperature Superposition Principle (TTSP) is applicable and verified. A model with a continuum spectrum called 2S2P1D (2S2P1D means two Springs, two Parabolic elements, one Dashpot), developed at the Ecole Nationale des Travaux Publics de l’Etat (ENTPE), is used to simulate the 3D LVE behaviour of tested bituminous mixture.

Keywords:

linear viscoelasticity; bituminous mixture; modelling; complex modulus; complex Poisson’s ratio.
General non-uniform quadrilateral cross-sections for thin-walled FG sandwich beams
Authors: Nguyen Tan-Tien , Nguyen Quoc-Hung , Le Thang D. , Le Hiep D.
Published: May 2021

The paper aims at introducing an analysis of thin-walled functionally graded sandwich beams for general non-uniform quadrilateral cross-sections. Generally, the materials are assumed to be graded through the thickness following a predefined shape while Poisson's ratio kept as a constant due to its less domination. The cross-section linearly varies from one end to another end of the beam. In order to relax the difficulties in modeling as well as capturing the behaviors of thin-walled functionally graded beams, a higher-order approach has been applied including warping, coupling distortions as well as Poisson's distortion. A multi-separated beam on each edge of the cross-section which is an application of the so-called beam-frame-modal method is adopted. Subsequently, the effects of these major importance along with anisotropy of materials are then fully considered. As a consequence, the analysis is able to extensively applied to closed-section beam-shells with different curvatures. In order to illustrate the accuracy and computational efficiency of the method, various examples have been conducted in which the results obtained from finite element package as ABAQUS are employed.

Keywords:

quadrilateral cross-section; thin-walled FG beam; higher-order coupling; beam frame modal.

Published: May 2021

In recent years, together with the boom of the industrial revolution 4.0, terms such as artificial intelligence (AI) are gradually gaining popularity engineering domain. This study proposed a number of AI models for predicting the axial strength in circular steel tube confined concrete (STCC) columns. Particularly, artificial neural networks (ANNs), support vector regression (SVR), linear regression (LR), and M5P were applied in this study. This study applied 136 samples of short and intermediate STCC columns infilled with normal strength concrete, high strength concrete, or ultimate high strength concrete to evaluate the AI models. Compressive strengths of concrete cylinders was ranged from 23.20 Mpa to 188.10 Mpa. The AI models were assessed by statistical indexes including MAPE, MAE, RMSE, and R. The analytical results revealed that the M5P the most effective AI model comparing to others. Comparing with the other models, predicted data obtained by the M5P model show the highest agreement with the actual data in predicting the axial strength of STCC columns. Particularly, the MAPE and R of M5P models were 10.62% and 0.977 respectively. Similarly, the RMSE by the M5P model was 330.38 kN which is the lowest value among 419.39 kN by the LR model, 337.84 kN by the ANNs model, and 857.11 kN by the SVR model. Therefore, the M5P model can be considered as a useful tool to accurately predict the compressive capacity of the STCC columns.

Penelitian ini bertolak dari keprihatinan guru terhadap proses belajar siswa di sekolah, terutama ditengah pandemi wabah Virus Corona yang melanda seluruh bidang kehidupan, termasuk bidang pendidikan. Hal demikian telah membuat proses belajar mengajar di sekolah cukup terhambat dan menyebabkan siswa terus diliburkan. Kondisi demikian menjadi kendala yang cukup serius bagi para guru dan siswa untuk terus melaksanakan proses belajar mengajar yang efektif di sekolah seperti dahulu. Untuk itu, diperlukan upaya kreatif dari para guru supaya pembelajaran tetap dapat dilangsungkan walaupun hanya dari rumah dengan memanfaatkan teknologi berupa aplikasi Zoom Meeting. Upaya kreatif yang dimunculkan guru supaya proses pembelajaran dapat terus berlangsung dan diyakini tidak membuat siswa bosan adalah model pembelajaran diskusi. Adapun permasalahan umum yang berusaha dicari pemecahannya, antara lain: (1) Pelaksanaan proses pembelajaran menggunakan metode diskusi; (2) Hasil belajar siswa terutama pada mata pelajaran PKn; (3) kendala yang dihadapi guru dan siswa dalam proses pembelajaran diskusi. Proses pengumpulan data menggunakan pendekatan kualitatif deskriptif dan instrumen yang digunakan adalah wawancara dan studi dokumentasi. Hasil penelitian menunjukkan bahwa (1) Proses belajar mengajar di SMP Negeri 3 Dedai menggunakan metode diskusi cukup berhasil; (2) Hasil belajar siswa cukup baik, walaupun sebenarnya kalau mau jujur, nilai mereka menurun, namun karena guru mempunyai pertimbangan yang cukup banyak, maka nilai siswa paling tidak diusahakan stagnan (3) Kendala yang dihadapi adalah pengeluaran orang tua siswa yang cukup besar berkaitan dengan kuota untuk internet, seringkali gangguan signal terutama pada saat cuaca buruk dan bagi siswa yang tinggal jauh dari pusat kecamatan diperlukan tempat khusus yang ada signal untuk mengakses internet. Kata kunci: Mata Pelajaran PKn, Metode Diskusi, Hasil Belajar

A SWITCHING GAIN CONTROLLER IN DRSIGNING OPTIMUM CONSTRAINT CONTROL PROBLEMS BASED ON GENETIC ALGORITHM
Authors: Awad Osama Ali
Published: May 2021

This paper introduces an iterative approach for the design of an optimum switching gain controller for a linear time invariant single input/single output (SISO) systems. The controller parameters are determined at different switching instants so as to improve the dynamic characteristics of a closed loop system and satisfy a set of inequalities. The approach is based on solving a constrained parameter optimization problem. Optimization is carried out based on the genetic algorithm (GA) in order to find the optimum number of switching, optimum switching instants and optimum controller parameters vector. All that in the sense of minimizing a certain time based objective function and satisfying a set of parametric and operating constraints. Constraints imposed on the controlled system may be in the form of design specifications and/or performance requirements. The technique is applicable for any controller structure, and gives a set of an optimum parameter values switched at optimum switching instants. Parameter values are function of the system states at these instants. Different systems are examined to show the applicability of the presented approach.
Online Course: Application Models in the Educational Process
Authors: Grechushkina N. V.
Published: May 2021

Digitalization of education and the development of electronic pedagogy as a branch of pedagogical science are the conditions that actualize the analysis of online courses application mo-dels which is the purpose of this study. Based on the analysis of scientific pedagogical literature, the article addresses the typology of online courses integration models implemented in the traditional (face-to face) educational process. The author has studied and summarized the various approaches to selecting  integration models of online courses  in Russian and  foreign scientific and pedagogical literature and developed a typology of patterns of online courses application based on three criteria: the organization of the educational process (characteristics: the character of the online course incorporating in the educational process, a way of organizing the educational process), the contents of traditional face-to-face and online components in the learning content (characteristics: a change in the structure of educational process, forms and methods of training), and the organization of interaction between the subjects of the educational process (characteristics: organization of pedagogical support, organization of pedagogical interaction between the subjects). This approach made it possible to pinpoint thirty-four models of online courses application and  integration. Each model implemented in practice can be identified unambiguously when typologizing by one characteristic of the corresponding criterion and refer to several types when considering its different characteristics.
