Information about score obtained from a test is often interpreted as an indicator of the student's ability level. This is one of the weaknesses of classical analysis that are unable to provide meaningful and fair information. The acquisition of the same score if it comes from a test item with a different level of difficulty, must show different abilities. Analysis of the Rasch model will overcome this weakness. The purpose of this study was to analyze the quality of the items by validating the national chemistry exam instrument using the Rasch model. The research sample was 212 new students of the Department of Chemistry at the State University of Medan. The data collected was in the form of respondent's answer data to the 2013 chemistry UN questions, which amounted to 40 items multiple choice and uses the documentation method. Data analysis technique used the Rasch Model with Ministep software. The results of the analysis show the quality of the Chemistry National Exam (UN) questions is categorized as very good based on the following aspects: unidimension, item fit test, person map item, difficulty test level, person and item reliability. There is one item found to be gender bias, in which men benefit more than women. The average chemistry ability of respondents is above the average level of difficulty of the test items

В статье сравниваются экономические кризисы 1929-1933 и 2008-2009 гг. Автор анализирует разнообразные причины кризиса 1929-1933 гг. и приходит к выводу, что среди них особую роль сыграла низкая покупательная способность населения США 1920-х гг. Реформы Ф.Д. Рузвельта 1930-х гг. увеличили покупательную способность населения в два раза, что серьезно способствовало выходу из кризиса. В современном экономическом кризисе главной причиной, на взгляд автора, была неоконсервативная экономическая политика, которой правительство США следовало на протяжении 30 лет начиная с 1980-х гг.

Upper Devonian brachiopods from the core of the Kurgan-Uspenskaya-1 key borehole (south-western outlying areas of Western Siberia)
Authors: Mizens A. G. , Mizens L. I.
Published: August 2021

Research subject. Brachiopods from the core of the Kurgan-Uspenskaya-1 parametric borehole. The borehole was drilled in the south of Western Siberia 80 km southeast of the Kurgan town. Brachiopods were collected at a depth of 1,525.4 m in the IV tectonic block (core interval 1,450–1,794 m) in the greenish-gray marls of the Famennian stage of the Upper Devonian.

Materials and methods. The paleontological material is presented in the form of complete undamaged shells and individual valves of small- and medium-sized brachiopods. The safety of brachiopods makes it possible to determine their species and genera, sometimes in open nomenclature. The article provides a brief description of the available material.

Results. 11 species of brachiopods of the subtype Rhynchonelliformea belonging to six orders and nine genera were identified. The following ten species were described: Orbinaria fallax (Pand.), Semiproductus amplus Bubl., Schuchertella sp., Dalejina? sp., Camarotoechia panderi (Sem.et Moell.), C. volucera Nal., Athyris tobolica Nal., Cleiothyridina tenuilineata (Row.), Cl. ex gr. pectinata (Sem. et Moell.), Retzia? sp. The presented information allows conclusions about the age of the sediments enclosing the brachiopods under study and expands the existing knowledge of both the composition of the Upper Famennian brachiopods of the basement of the south of Western Siberia and their geographical and stratigraphic distribution.

Conclusion. An analysis of the stratigraphic distribution of the described brachiopods taking into account data on foraminifera allowed us to determine the age of the host rocks as the very top of the Famennian stage. The composition of the brachiopods allows these rocks to be correlated with coeval deposits of the East European Platform, Timan, the Urals, Kuzbass, the Gorny Altai, Kazakhstan and North America.

Authors: Chandrawati Putri Wulandari
Published: August 2021

Education is an essential need and an important element to create a broad-minded youth. While inIndonesia, the rate of tuition fees is still imbalanced with the economic rate. Thus, many peopledecided to discontinue their higher education. Decision making plays an important role to manageorganizations, including in educational institutions, as one of the main duties in managerial is makingdecisions. This study took place in a midwifery academy in Malang. In response to this situation, theacademy has a policy to alleviate students by paying the tuition fees in instalments. However, manystudents are in arrears as the result of this policy. Thus, management needs to take some considerationbefore making a decision toward the problem. Those considerations require high accuracy and timeconsuming to process information that support decision making. Currently, the decision-makingprocess in this academy is still semi-automated, in which some processes are still done manually,which affect longer time to make decisions, and the accuracy of calculations could not be fullyguaranteed. According to this condition, the purpose of this research is to design a decision supportsystem that enables us to process information for decision making and to offer decision alternativesfor decision makers. This research employs Systems Development Life Cycle (SDLC) with a decisiontable as a method to create decision alternatives. The prototype was developed using Visual StudioC#.Net. The result shows that by using the proposed prototype of DSS, decision makers can reduce5-10 minutes of decision making process compared to the old semi-automated system which stillrequired manual calculation and data collection and analysis before making the decision. A completedata and more detailed parameters for decision criteria are required to implement the proposedprototype of DSS in the institution with more objective consideration in the decision making processas the future work.

Published: August 2021

Background:

We reviewed the clinical outcomes of a procedure that combines endovascular embolization and a direct surgical approach in a hybrid operating room (OR) for the treatment of refractory dural arteriovenous fistulas (dAVFs).

Methods:

All patients with intracranial dAVFs who underwent a procedure combining endovascular embolization and direct surgical approach with biplane angiography or a robotic C-arm system in a hybrid OR between February 2004 and June 2020 were considered. Borden grading, occlusion rate, pre-and post-operative modified Rankin Scale (mRS) scores, and complications were retrospectively investigated. The pre-and postoperative mRS scores were compared using the Wilcoxon signed-ranks test.

Results:

We evaluated 14 arteriovenous fistulas (AVFs) in consecutive 13 patients. Of these, ten AVFs were previously treated with endovascular embolization, ten were located in the transverse-sigmoid sinus, and four in the cortical vein. The Borden grade was II in two AVFs and III in 12 AVFs. Immediate occlusion of the AVF was achieved in 13 AVFs, and gradual occlusion was observed in one case. The median preoperative mRS was 1 (0–3), whereas the median postoperative mRS was 0 (0–1) which indicated marked improvement (P = 0.006). Complications including postoperative transient visual disturbance and intraprocedural extravasation were observed in only two cases.

Conclusion:

The combination of endovascular embolization and direct surgical approach in a hybrid OR could achieve sufficient occlusion of refractory AVFs with acceptable complication rates and improved symptoms.
Microsurgical resection of a giant cervico-medullary ependymoma: 2D-dimensional video
Authors: Oberman Dan Zimelewicz , Machado Raphael , Ribeiro Luiz Felipe , Von Zuben Daniela de Oliveira , Bahia Paulo Alves , Schiavini Hugo Corrêa , Monteiro Ruy
Published: August 2021

Background:

Ependymoma is a slowly growing benign neoplasm that constitutes 3–9% of all neuroepithelial spinal cord tumors.[3,4] They rarely involve the cervicomedullary junction where they both compress the distal brainstem and upper cervical cord. Due to the critical contiguous structures, gross total resection of these lesions may result in significant morbidity/mortality.[1,2] Utilizing intraoperative neuromonitoring can help limit the risks of removing these lesions. Not when considering the risk/complications of partial versus total resection, the surgeon should keep in mind that they are benign slow growing tumors with relatively good long-term survivals following partial removals. This surgical video shows the surgical strategy and management of a giant cervicomedullary ependymoma performed in a 23-year-old female.

Case Description:

A 23-year-old female presented with cervical pain and quadriparesis of 1-year’s duration. The MR with/without gadolinium showed a large intradural, intramedullary cervical spinal cord tumor that severely expanded the spinal cord. It contained a significant cystic component, extending from the lower brain stem to the inferior aspect of C7. The lesion was hyperintense on T1 and T2 sequences and demonstrated minimal contrast enhancement. Surgery warranted a posterior cranio-cervical midline approach consisting of a suboccipital craniectomy with laminotomy. The pathological diagnosis was consistent with an ependymoma (WHO I). Fifteen days postoperatively, the patient was discharged with a minimal residual quadriparesis that largely resolved within 6 postoperative months. Three months later, the MRI confirmed complete tumor removal of the lesion. Notably, longer-term follow-up is warranted before complete excision can be confirmed. If there is a recurrence, repeat resection versus stereotactic radiosurgery may be warranted.

Conclusion:

This video highlights a safe and effective surgical technique for the resection of a giant cervicomedullary ependymoma.

Published: August 2021

Description of the subject. Pericopsis elata (Fabaceae) is a long-lived light-demanding tree from African rain forests that produces timber of high economic value. Natural populations suffer from overexploitation and a deficit of natural regeneration. Plantations could increase its production and limit the pressure on natural forests. However, we lack knowledge on the influence of spacing and seed tree origin on tree growth to optimize plantation protocols. Objectives. This study evaluated the impact of sapling density and seed tree origin on the growth in diameter and height of P. elata plants, 20 months after plantation. Method. Seeds were collected on 19 mother trees in a 400 ha natural stand near Kisangani (DRC). In October 2017, seedlings were transplanted in a Nelder design plantation with three replicates, to compare sapling growth at 10 contrasting plant densities under full sun. Diameter and height increments of 540 plants were analyzed according to local competition and maternal origin using generalized additive models. Results. Twenty months after planting, height growth peaked at an intermediate density of 47,000 stems·ha-1 (165.6 ± 39.2 cm·year-1), while diameter growth peaked at a lower density of 4,200 stems·ha-1 (24.6 ± 8.3 mm·year-1). The maternal origin of saplings affected their growth, the coefficients of variation among mother trees reaching 7.6% and 6.4% for diameter and height increments, respectively. The initial diameter affected positively diameter growth while the initial height did not influence height growth. Conclusions.

Introduction. Le moustique Aedes aegypti, vecteur majeur d’arbovirus, se développe dans un large panel de réservoirs artificiels en zone urbaine. Ces gîtes larvaires sont exposés à des conditions biotiques et abiotiques variables pouvant influencer la capacité vectorielle du moustique adulte et, par conséquent, le risque de transmission de pathogènes. Ici, nous recensons l’état des connaissances sur les propriétés physico-chimiques et microbiologiques des habitats aquatiques d’Ae. aegypti qui affectent le comportement de pré-oviposition, le développement et la capacité à transmettre les virus de ce Culicidae. Littérature. La grande variabilité spatio-temporelle des propriétés abiotiques et biotiques des gîtes d’Ae. aegypti rend complexe leur caractérisation. Certains facteurs biotiques (matière organique, larves congénères, microbiote) et abiotiques (salinité, température, pH) des gîtes ont des effets forts et directs sur le développement des larves et se répercutent sur les caractéristiques physiologiques et morphologiques du moustique adulte telles que la taille, la fécondité, la longévité et sa capacité vectorielle. Conclusions. Au vu de l’influence du gîte larvaire, et notamment de son microbiote, sur des nombreux traits phénotypiques chez Ae. aegypti, des efforts sont encore requis pour mieux comprendre comment la variabilité naturelle des gîtes façonne la capacité vectorielle des populations de cette espèce invasive à travers le globe.
