Authors: Simbolon Nurmala Elmin , Febrianti Yusnita
Published: October 2020

The use of YouTube resources as learning materials becomes increased in English language teaching (ELT), especially when implementing the content-based instruction (CBI) approach. In addition to its importance during the recent global restriction caused by the Corona Virus Disease (COVID-19), one of the benefits of using YouTube is perceived to provide authentic learning, which can improve the student learning experience, hence prepare graduates in the future career. While several studies have shown the benefits of using videos in ELT classrooms, this study argues that consideration for suitability and relevance of the visual materials should include the contained meaning potentials; experiential, interpersonal, and textual aspects. The study analyzed three videos used as teaching and learning materials in a Maritime English course at a vocational university where the research was conducted. Foregrounded by SFL theories, the analysis of the videos utilized Multimodal Video Analysis (MMA) Software to present a selection process of teaching and learning materials in the form of YouTube videos. Findings show the specifics of the meaning potentials in the videos used for the teaching and learning materials of the Maritime English course. The results also highlight the positive qualities and drawbacks identified in the videos. Additionally, the findings of the study provide guidelines for selecting video materials suitable and relevant to the Maritime English course in vocational higher education in Indonesia.

Published: October 2020

The Indonesian Testing Service Centre (ITSC) has developed an online standardized test called TOEP (Test of English Proficiency) as a fresh alternative for measuring the test takers’ listening and reading proficiency. To ensure its quality, the TOEP scores need to be validated against the scores obtained from another established standardized test, in this case the ITP-TOEFL. This study aimed at finding out to what extent the range of scores which are measured by TOEP can predict the scores obtained from ITP-TOEFL. A quantitative approach was applied in this study, focusing on the analysis of scores obtained by 1,048 people taking TOEP in 2016, 2017, and 2019 and 383 testees had taken both TOEP and ITP-TOEFL. A regression analysis was conducted to establish the prediction equation of TOEP to ITP-TOEFL. The range of scores of proficiency measured through TOEP was estimated using the advanced item response theory, especially the information function value. The results of analysis show that TOEP can predict test takers’ English proficiency in the range of minimum 310 and maximum 656.34 at the ITP-TOEFL scales. It can be concluded that TOEP has a good predictive validity to ITP-TOEFL.

Published: October 2020

Die bei Industrie 4.0 angestrebte Selbstorganisation der Produktion wird im Wesentlichen ermöglicht durch ein im Kern normiertes Dienstesystem. Dieses benötigt dabei einen Grad von Interoperabilität zwischen Dienstesystemteilnehmern, der tatsächlich Plug-and-produce ermöglicht. Die Haupterwartungen an ein solches Dienstesystem liegen beim einfachen Auffinden (Erforschungsmechanismen) und Verstehen von Daten (maschinenlesbare Semantik). Die Dienstearchitektur, die dieser Beitrag behandelt, dient sowohl als Basis für die Implementierung der Verwaltungsschale, als auch der Industrie-4.0-konformen Kommunikation. Die zugrundeliegende Dienstearchitektur beschreibt dabei die statische Grundstruktur der Daten (das Industrie-4.0-Informations-Meta-Modell), die interaktiven Zugriffsschnittstellen zur Erforschung und Änderung der Daten (die Industrie-4.0-Informations-Dienste) sowie die Adressierung von Diensten in einem Dienstesystem. Auf Basis dieser Architektur können höherwertige Dienste zur Organisation der Produktion und Handhabung der Produkte (die Industrie-4.0-Anwendungsdienste), aber ebenso zur Selbstverwaltung der Ressourcen/Assets des Automatisierungssystems (Industrie-4.0-Plattformdienste) technologieunabhängig und interoperabel erstellt werden.

Specialists from Children Orthopedic Clinic (CITO) and Institute of Medical Technology elaborated therapeutically active implants on the base of N-vinilpirrolidone and methylmethacrylate with different additives. Those implants were successfully applied in clinical practice. Experimental study on rabbits showed the possibility of implants to stimulate osteogenesis. Various types and shapes of implants were elaborated using different combinations of additives. Minimum invasive surgical intervention and indications to implants application were worked out. From 1987 to 2001 one hundred thirteen patients with various pathology (obstetrical paresis, clubfoot, juvenile femur head ephiphysiolysis, congenital hip dislocation, funnel-shaped deformity of thorax, dystrophic varus deformity of femur head, osteochondropathy of lower limbs) were treated surgically using new implants. At 35 years follow up good and excellent anatomic and functional results were noted in 89% of cases.

Published: October 2020

Aneurysmal bone cyst refers to tumor-like lesions with an etiology not fully elucidated [10, 13, 14]. Until recently, bone cysts in children were classified as tumor processes [4]. A.P. Berezhny [1], based on a clinical and radiological study and analysis of a large number of observations, came to the conclusion that primary cysts in children, including aneurysmal ones, are a dystrophic process, usually affecting one bone without damaging the growth zone and adjacent bones. The same opinion is shared by some foreign authors [6]. However, at present, the point of view is more widespread, according to which an aneurysmal bone cyst is a reactive process that develops in response to bone damage [3, 5, 9, 10, 14].
Angular Stability Plate System (LCP) - the new AO standard for plate osteosynthesis
Authors: Neubauer Th. , Wagner M. , Hammerbauer Ch.
Published: October 2020

Locking Compression Plate (LCP) represents the latest development of AO plates, combining the features of conventional plates and internal fixators. This is achieved by a so-called combi-hole merging the Dynamic Compression Unit (DCU) of the DCP and the threaded hole of locked plates. Therefore all kinds of conventional screws as well as threaded locking head screws (LHS) can be inserted through the plate depending on the specific local requirements. However, LCP represents not a new plate per se, but rather a plate/screw system to enrich the well known АО-plate designs with the option of interlocking. As the mechanical characteristics have not changed by adding a combi-hole the complete set of small (3,5 mm) and broad (4,5/5,0 mm) АО-plates is available. Additionally LCP-systems adapted to certain anatomic regions, like the proximal humerus and distal radius as well as Tomofix2 plates for osteotomies have been developed. We report about our first experience in clinical use of LCP. Prom April 2000 till December 2002,310 LCP systems have been implanted in 274 patients. 303 plates (97,7%) were implanted for fixation of 285 fractures with different localization in 267 patients, including 17 pediatric fractures (5,9%),9 periprosthetic fractures (3,2%),5 delayed-unions (1,8%) and 4 pathologic fractures (1,4%). Seven plates (2,3%) were implanted to fix osteotomies. Of all plates 111 (35,8%)) implants were fixed with locking head screws,194 (62,6%) with both types of screws and only in 5 plates (l,6%o) conventional screws were used. 73 (23,5%o) of all plates were inserted using a minimal-invasive approach and 237 (76,5%) via an open procedure. Postoperative complications occurred in 14/267 patients (5,2%) exclusively treated for fractures, representing a complication rate of 5,2%o in 15/285 fractures. Loosening of implants were seen in 1,4%), deep wound infection in 1,05%), osteomyelitis, refracture and postoperative hematoma in 0,7%o, respectively. Secondary malalignment and problems with implant removal occurred in 1 patient (0,35%), respectively. No delayed or non-unions were observed. In LCP all options of plate osteosynthesis are included, so fixation can be adapted more accurately to the local situation and operative procedure is facilitated.
Tactics of surgical treatment of closed fractures of long bones of the extremities in patients with polytrauma in the early period
Authors: Sokolov V. A. , Byalik E. I.
Published: October 2020

Results of the treatment of 218 victims with polytrauma were analyzed during the period from 1998 to 2202. There were 127 patients with one and 91 patients with several closed fractures. Authors consider osteosynthesis for closed long bone fractures to be an urgent operation of third term. Osteosynthesis is absolutely indicated to the patients with psychomotor excitation, in cases of the threat for skin perforation by bone fragments and in patients requiring intensive nursing for their life rescue. The choice of operative method depends on polytrauma severity and fracture type. When osteosynthesis is petformed by urgent indications in patients with polytrauma the requirements to osteosynthesis stiffness are higher than in isolate injuries, as the rotation displacement, migration and fixator deformity frequently take place in unconscious patients who need constant intensive nursing. In patients with concomitant thorax injury urgent intramedullar osteosynthesis by nail is contraindicated due to the possibility of fat embolism syndrome development. In these patients plate osteosynthesis is preferred. If there are no absolute indications to urgent osteosynthesis this operation could be petformed on 310 days after trauma using lightly traumatic and invasive methods not waiting for the complete normalization of homeostasis parameters and restoration of soft tissues in the fracture zone. In closed long bone fractures tactics of early osteosynthesis allows to decrease the rate of hypostatic complications and mortality by more than 10% and achieve good functional results.

Published: October 2020

In 19 patients with typical clinical picture of 1-II bilateral coxarthrosis method of functional myoneurostimulation was used as monotherapy. Treatment course consisted of 15 procedures, 30 minutes each. Treatment results were assessed clinically and bimechanically. After treatment the intensity of pain syndrome decreased significantly; strength of muscles surrounding hip joint increased; the limitation of joint movement due to adductive contracture decreased; walk pattern was normalized. As a rule clinical status of patients that was achieved during the treatment lasted for 6 months. After that mentioned positive changes gradually became less pronounced. Repeated courses of stimulation improved physical condition of patients. Authors believe that efficacy of myoneurostimulation is determined by two main factors, i.e. influence of electric current upon articular and periarticular structures (neuro-muscular and ligamentous system, particularly) at movement as well as significant improvement blood circulation in the pathologic region.

The authors have elaborated a new method for conservative treatment of femoral head aseptic necrosis (FHAN) at early stages of the disease (prior to cartilaginous layer collapse). The method consists of performance of prolonged epidural analgesia by administration of local anesthetic through epidural catheter with dosed speed for 6 - 8 days. Drug sympathectomy results in vascular tension drop that favours the improvement of microcirculation in hip joint region. Results of that method application in 24 patients show that it enables to cup off the pain syndrome and restore patient's functional abilities directly after treatment course completion. Remission lasts for up to 12 months. Application of the proposed method enables to postpone performance of total hip arthroplasty for the period of up to 6 years.

Experimental study of the influence of crystalline silicium upon the damaged physis of the proximal femoral growth zone was performed in 24 Chinchilla rabbits. Defect of growth zone was created by drilling (2.6 mm in diameter). In first experimental group a metallic screw was inserted into the created defect. In the second group silicium monocrystal 5x5x0.5 mm was placed into the defect next to the metallic screw. In control animals only the defect was created. In animal from 1st and control groups roentgenological picture showed the development of deformity in the operated extremity. No deformity was detected in animals from 2nd experimental group. Positive effect of crystalline silicium upon the damaged growth zone function was noted. Further study of this phenomenon may be perspective for the elaboration of new implantation materials with a view to stimulate regeneration of affected physis, preservation of its function, bones deformity prevention and correction.

Nanostructural biocomposite material Collapan and platelet-rich autoplasma (PRP) were applied for the treatment of 158 patients with non-consolidating fractures and pseudarthrosis of extremities' long bones. It was shown that combined application of Collapan and PRP was available, safe and effective measure for activization of reparative bone regeneration. Consolidation of fractures and healing of pseudarthroses was achieved in 97.8% of patients. In control group (traditional surgical treatment) positive results was achieved in 81.4% of patients. Terms of fracture consolidation reduced by 11.0±2.3 days, of pseudarthroses healing - by 20±4.3 days. Nanostructural Collapan is a perfect matrix for isolation of autologous growth factors from platelets that contribute to fracture healing activization.

Published: October 2020

Analysis of CITO outpatient department archives has shown that practically from 20 to 30% of patients with spine pathology are suffering from scoliosis. The most common types are lumbar and thoracolumbar scoliosis. Progression of lumbar scoliosis goes on after growth completion and is accompanied by formation of pronounced degenerative changes in the spine. Clinically the course of the disease is aggravated by marked persistent pain syndrome. Results of surgical treatment performed at CITO spine pathology department with application of ventral and dorsal instrumentation have been analyzed for 118 patients with lumbar and thoracolumbar scoliosis. Eighty of those patients were operated on in childhood and juvenile age, 38 patients at the age of 25 - 70 years. Use of ventral instrumentation enabled to achieve high degree of lumbar and thoracolumbar scoliosis correction - up to 72% of initial deformity, average derotation made up 12.9° or 44.3% of initial rotation. Use of dorsal instrumentation is also effective for surgical treatment of lumbar and thoracolumbar scoliosis (66.8% of lateral curvature). Screw fixation ensures higher degree of the lateral curvature (68.2%) and sagittal profile as well as rotation component (33.1% of initial value). Presence of focal neurologic symptomatology is the indication to decompressive operations followed by instrumental fixation and posterior fusion. Defor-mity correction is performed only within the limits of deformity mobility

Study included 168 patients (31 women and 138 men, aged 17-47 years) to whom anterior cruciate ligament (ACL) autoplasty was performed during the period from 1996 to 2003. Kits of mechanical instruments with metric and calibration scales were used for ACL reconstruction. In 150 patients ACL reconstruction was performed using patellar ligament with 2 bone blocks, in 19 patients using tendons of semitendinous and gracilis muscles on the affected side. Formation of the axes for tibial and femoral channels was based on 5 criteria. Analysis of postoperative knee joint X-rays of 132 patients (73%) detected graft location disturbance in 46 patients (37%). Assessment by Lysholm scale showed 24.1% (27 patients) of satisfactory and poor results. By IKDC form 1995 the share of C and D groups increased up to 34.8% (39 patients).

Results of operative treatment using radical thoracoplasty in 31 patients with funnel breast were analyzed. Mean age of patients was 14.98±4.36 years. All patients had concomitant spine deformity. For purpose of cosmetic effect improvement the mini-invasive submammary accesses were used. Fixatives of sternocostal complex from nickel-titanium with shape-memory were worked out. The shape memory effect was achieved by cooling of the implant that resulted in implant plasticity. After being inserted the implant restored its original shape. That technique allowed achieving full correction of the deformity and positive cosmetic effect in all patients. No complications associated with plate migration were revealed. Radical thoracoplasty with thoracocostal complex stabilization by plate with shape-memory effect is pathogenetically justified and allows correcting the funnel chest of any degree and form and is indicated to patients of any age groups.
