Damage Control Orthopedic Surgery.
Authors: Brahimi Fatmir , Selmani Edvin , Duraj Leard
Published: February 2019

The concept of damage control surgery was first described for the purpose of treating medically un-stable patients with abdominal trauma. The purpose of such surgery is rapid control of hemorrhage and contamination, not definitive repair of injuries. The goal is to improve survival of patients with the potentially lethal triad of hypothermia, acidosis and coagulopathy. Definitive repair of injuries and abdominal closure are not performed at the time of initial laparotomy. Rather, the abdominal wound is left open, a dressing is placed, and the patient is transported to the intensive care unit for continued re-suscitation. This includes optimization of hemodynamic condition, respiratory support, warming, and correction of coagulopathy. Following successful resuscitation, when the patient is medically stable, a return to the operating room is scheduled for repair of injuries and abdominal closure.

Published: February 2019

Background: Traumatic brain injury (TBI) is the leading cause of mortality and invalidity worldwide.

Objective: To explore whether traumatic brain injury may be a risk factor for subsequent stroke and to evaluate the role of other risk factors correlated with TBI and stroke.

Methods: We analysed 643 patients presented in the emergency department of Trauma UHC, from 1stof June 2011 - 1st of December 2011. We evaluated the following factors: age, gender, and severity of head trauma, type of head trauma, systemic hypertension, atrial fibrillation, and diabetes mellitus.

Results: During 1-year of follow upperiod 32 (4.97%) strokes occurred in TBI patients. The evaluation was done in correlation with the other risk factors taken into account in the study.

Conclusions: The role of TBI is underestimated in the evaluation of stroke. This study demonstrated that during the first year after TBI, 13.53 % of patients experienced stroke. After careful statistical cor-relations with the selected co-morbidities, we found that the diagnosis of stroke was strongly related with TBI.

Authors: Nguyen Hai Thanh , Ngo Cuong Quoc , Nguyen Hung Viet
Published: February 2019

Researches of human Brain Computer Interface (BCI) for the objective of diagnosis and rehabilitation have been recently increased. Cerebral oxygenation and blood flow on particular regions of human brain can be measured using a non-invasive technique – fNIRS (functional Near Infrared Spectroscopy). In this paper, a study of recognition algorithm will be described for recognizing whether one taps his/her left hand or right hand. Data with noises and artifacts collected from a multi-channel system will be pre-processed using a Savitzky- Golay filter for getting more smoothly fNIRS data. Characteristics of the filtered signals during left and right hand tapping process will be extracted using a Polynomial Regression (PR)-Support Vector Machine (SVM) algorithm. Coefficients of the polynomial determined by the PR algorithm, which correspond to Oxygen-Hemoglobin (Oxy- Hb) concentration changes, will be applied for the recognition of hand tapping. Then the SVM will be employed to validate the obtained coefficient data for the hand tapping recognition. Experimental results have been done many trials on 3 subjects to illustrate the effectiveness of the proposed method.

TINJAUAN UMUM TENTANG EKONOMI
Authors: Gozali M. Junus
Published: February 2019

Ekonomi adalah pengetahuan tentang kegiatan yang mengatur urusan kekayaan dalam bidang produksi, distribusi dan konsumsi. Masalah ekonomi ini telah dijelaskan dalam suatu hadits yang diriwayatkan oleh Anas Ibn Malik RA. bahwa Nabi Muhammad SAW telah memerintahkan kepada salah seorang sahabat Anshar untuk bekerja, berusaha mencari kayu bakar ke bukit, dan ia mengerjakan (produksi), menjual (distribusi), dan membeli makanan (konsumsi), serta bersedekah (melaksanakan peduli sosial).Pada saat ini terdapat dua sistem ekonomi, yang menguasai dunia, yaitu sistem ekonomi kapitalis dan sosialis. Kedua sistem ini masing-masing memiliki konsep yang bertolak belakang. Sosalisme memiliki konsep ekonomi kolektif, sedangkan kapitalisme memiliki kebebasan indvidu (liberal). Di samping perbedaan, yang berlolak belakang itu, keduanya mempunyai persamaan, yaitu aktivitas perekonomiannya memiliki watak materialisme murni.Berbeda dengan kedua sistem ekonomi di atas, sistem ekonomi Islam adalah sistem ekonomi yang berketuhanan. Di samping bersifat material, namun di dalamnya tidak mengabaikan aspek spiritual (ibadah). Sendi dari aspek spiritual adalah kesadaran individu muslim akan ketaatan kepada Allah dan Rasul-Nya. Dengan menempatkan Allah SWT pada puncak atas, maka segala aktivitas ekonomi dalam Islam. tidak akan terlepas dari pengawasan dan petunjuk yang diberikan di dalam al-Qur'an dan al-Hadits, baik, menyangkut dengan masalah produksi, distribusi, maupun konsumsi. Allah SWT melarang terhadap cara memperoleh barang produksi dalam mendistribuaikannya atau mengkomsumsikannya dengan jalan yang balil, kecuali dengan aktiuitas yang sah berdasarkan kebebasan dengan kesukarelaan masing-masing pihak, tidak curang dan tidak ada unsur paksaan atau tekanan. Dengan demikian tampaklah bahwa Islam telah menyelesaikan masalah bagaimana agar manusia dapat memanfaatkan (mengelola) kekayaan yang ada, dan inilah sebenarnya yang dianggap sebagai masalah ekonomi bagi suatu masyarakat. Sebagai kesimpulan dalam meninjau masalah ekonami, Islam hanya membahas masalah bagaimana cara memperoleh kekayaan, mengelola dan mendistribusikannya, sesuai dengan aturan al-Qur'an dan al­Hadits, dan mendapat hasil pemikiran para ulama. Dengan demikian hukum-hukum yang menyangkut masalah ekonomi dibangun atas tiga kaidah, kepemilikan (property), pengelolaan kepemilikan dan mendistribusikan kekayaan di tengah-tengah maayarakat.Keyword: Qur'an/Hadit, Ekonomi, Sistem

Setelah bangsa Arab melakukan penaklukan ke berbagai wilayah di sekitarnya, banyak di antara para penduduk daerah tersebut yang masuk Islam. Sebagai konsekuwensinya, mereka pun mempelajari bahasa Arab guna memahami ajaran Islam yang terkandung dalam al-Qur'an. Seiring dengan itu, percampuran antara bangsa Arab dan non-Arab (ajam) telah mengakibatkan terjadinya pencemaran (lahn) dan ketidak fasihan dalam berbahasa Arab. Sesuatu yang dapat merusak kemurnian bahasa Arab. Didorong untuk memelihara kemumian Bahasa al-Qur'an inilah kehadiran nahwu (gramatika bahsa Arab) sebagai sebuah disiplin ilmu menjadi penting.Dipelopori oleh para ulama di daerah Basrah (lrak). Ilmu nahwu tumbuh menjadi sebuah disiplin ilmu yang mandiri dan berkembang menjadi sebuah aliran nahwu terkenal yang biasa disebut dengan madzhab Basrah. Pada perkembangan berikutnya muncul berbagai aliran lain yang memiliki karakteristik tersendiri dan metode yang berbeda dengan Madzhab Basrah, seperti aliran Kufah, aliran Baghdad, alirn Mesir dan aliran Kordoba. Namun, dari sekian aliran tersebut hanya madzhab Kufah-lah yang dapat dikatakan setara dengan madzhab Basrah. Sehingga wacana gramatika bahasa Arab sempat diramaikan oleh perdebatan panajang antara para cendekiawan nahwu dari kedua aliran tersebut.Tulisan ini mencoba melacak motif-motif munculnya dan sejarah berkembangnya ilmu nahwu sebagai sebuah disiplin tersendiri.Kata Kunci: Nahwu, Lahn, Madzhab, Basrah, Kufah.

Perbuatan hukum misalnya jual beli bukanlah suatu perbuatan hukum yang sudah final pada saat terjadi suatu "akad" atau ''perjanjian" dianggap kesepakatan awal sesuai dengan asas konsesualisme menurut hukum perdata barat, akan tetapi dalam hukum Islam, akad atau perjanjian akan menjadikan syarat penyerahan atau "levering" sebagai suatu patokan telah selesainya perbuatan hukum jual-beli. Dalam hukum bisnis Islam bisa saja "penyerahan barang yang dibeli" sudah dilakukan pada saat akad ditutup atau ditanda tangani. Akan tetapi masing-masing pihak baik pembeli atau penjual tetap mempunyai opsi (pilihan) untuk membatalkan atau melangsungkan perbuatan hukum jual beli.

OPTIMALISASI DAN PERAN LINGUISTIK DALAM PENGAJARAN BAHASA ARAB DI INDONESIA
Authors: Ismail Achmad Satori
Published: February 2019

Untuk mengembangkan pel,qjaran bahasa Arab di Indonesia pada saat ini perlu dilakukan berbagai upaya. Di antara upaya yang perlu dilakukan tersebut adalah dengan mengoptimalkan peran linguistik, terutama linguistik terapan, dalam pengajaran bahasa Arab. Hal ini mengingat bahwa pada dasarnya proses pengajaran bahasa menuntut pengetahuan tentang prinsip-prinsip bahasa yang dipelajari. Tanpa bantuan teori-teori linguistik, guru bahasa Arab akan menemukan kesulitan dalam memberikan deskripsi yang akurat tentang bahasa dan situasi penggunnya. Untuk itulah teori-teori linguistik  umum,  sosio-linguistik, dan psiko-linguistik perlu mendapatkan perhatian dalam proses pengajaran bahasa Arab. Pemanfaatan linguistik dalam pengajaran bahasa Arab setidaknya dapat dilakukan dalam proses memilih bahan pelajaran, menentukan tahapan pengajaran, proses penyampaian materi pengajaran, dan pelaksanaan evaluasi pengajaran bahasa.Kata Kunci: Linguistik, Pengajaran Bahasa Arab, Error Analysis

Resource Planning For a Single Landfill Site Selection Model Based on Greedy Strategy: A Case Study
Authors: Azriati Mat Nur , Benjamin Aida Mauziah , Abdul-Rahman Syariza
Published: February 2019

Landfilling, which has emerged as the most common method for disposal of solid waste and selection of appropriate landfill for solid waste management, is a crucial aspect in urban planning. It is compulsory to consider the various criteria, such as environmental, economic, and social criteria, in order to get the best search outcomes that can minimise the adverse effects of the surrounding population. As widely known, the process of selecting new landfills is divided into two important phases, which are: 1) the determination of potential candidate locations through an initial screening, and 2) suitability assessment based on several criteria. Previously, issues related to landfill site selection have been successfully solved by using Geographic Information System (GIS) and Multiple Criteria Decision-Making (MCDM) techniques, either individually or as an integrated approach. With that, this research aims to assist the authorities in planning a single landfill site selection by utilising all the available resources, which translates being cost-effective. Therefore, the Nearest Greedy (NG) technique had been employed to assess all five potential candidate locations by considering several related constraints. Next, the solutions were ranked based on the total distance travelled by vehicles in completing the overall waste collection process. The proposed approach was tested on a real dataset of the waste collection problem in a district located within the Northern Region of Peninsular Malaysia, which consisted of 146 residential areas and involving up to 18749 unit premises. After that, the solution obtained was compared with the present operating landfill facility, in which Candidate 4 appeared as the best alternative with a 6.74% reduction of total distance travelled, in comparison to the present operating landfill method. As such, the proposed solution may aid the local authorities and serve as a guideline in identifying suitable locations for waste disposal based on availability resources, which can discard unnecessary expenditure, such as fuel consumption.
Provision for Bad & Doubtful Financing and Contingency Reserve Management: Assessing Resilient and Stable Islamic Banks
Authors: Abu Bakar Mohd Afandi , Mohd Nasir Noormahayu , Abd Razak Farrah Dina , Kamsi Nor Samsinar , Che Ahmad Asmalia
Published: February 2019

Banks will not be resilient and stable if the provision for bad and doubtful financing (PBD) and contingency reserve (CR) failed to play its role as bank operational buffers whenever there is an economic condition disorder. Every firm has to face the financial uncertainties and the sudden shock of economic activity disorder, which will directly affect their operations. The management of PBD and CR is necessary to make the bank well protected. To verify the resiliency and stability of the Islamic bank, hence, this paper empirically examines the bank management of PBD and CR. An unbalanced panel data analysis was conducted on 67 Islamic banks from various countries for the period of 2000-2014. The empirical evidence shows, although the bank PBD does fulfil the resiliency and stability behaviour conditions, the insignificant relationship of the M2 growth and CPI growth to the PBD growth need some consideration from the banks and policy makers. The finding also provides an indication that only the current year profit growth behaviour is positively correlated to the CR growth. The findings recommend the Islamic bank PBD and CR management need to be sound to make it more resilient and stable.
Analysing Punishment of Corporations in Water Pollution Case
Authors: Abdul Wahab Harlida , Yaacob Nurli , Mohd Anuar Haslinda
Published: February 2019

For a stiffer penalty, punishment for the environmental violation was generally increased from Malaysian Ringgit 10,000 to Malaysian Ringgit 100,000 and from two years to five years imprisonment twenty years ago. Although the penalties are improved, the cases of environmental pollution and violation are yet increasing. This article examines the trend of punishment for environmental violations that imposed on the corporate entities or corporations. Focusing on the case of water pollution, the observations are made to the penalty’s provisions of the Environmental Quality Act 1974 and the penalties imposed through the court judgment against the corporations. For this purpose, cases and charges of water pollution are obtained from the records of Department of Environment Malaysia. Moreover, views of the judges of the Green Court on both laws and judgments relating to penalties are acquired. The study found that: (a) there is a wide gap between the punishment imposed by law and the penalties positioned by court; (b) corporate entities are willing to pay fines; (c) courts are not ready to impose imprisonment for default of payment to the corporations or individuals within the corporations. Though addressing water pollution, the findings should be far-reaching surpassing other types of environmental pollution.

Published: February 2019

The features of primary-to-secondary leak accident progression with high pressure injection system (HPIS) flow control using a control valve (CV) compared with HPIS operation without CV were analyzed within the scope of the revised accident management strategy. The management strategy for primary-to-secondary leak accident designed for symptom-oriented emergency instructions of South Ukrainian NPP unit 3 was taken as a basic strategy. The evaluation of CV efficiency applied two modes for CV (pressurizer filling mode and supporting of margin to saturation in the primary system mode), which have been used depending on the stage of the accident (before and after level recovery in pressurizer). Research was carried out for the accident progression without any equipment failures and for the accident with the failures of emergency gas removal system valve in the fully open position. In addition, the experts performed comparative calculations of the integral leak flow for the different diameters of the leak for cases with using and without using CV for HPIS. The calculation results were shown that automated work of the CV can reduce integral leak flow and ensure an adequate margin to saturation in the primary system, but comes with the self-oscillations phenomenon.

Authors: Kovbasenko Yu.
Published: February 2019

The paper considers the impact of different operational conditions on VVER-1000 spent fuel isotopic composition. Such operational conditions include the presence or absence of absorber rods in guide tubes of fuel assemblies, changing the concentration of boric acid dissolved in the moderator (water) during the campaign, fuel and/or moderator temperature. Moreover, the impact caused by manufacturing tolerance applied while manufacturing fuel assembly was analyzed by weight of fuel and by its enrichment. Calculations were made for reactor cells of fuel assemblies for VVER-1000. They were composed of the new fuel assemblies of Westinghouse Company and the typical fuel assemblies of Russian TVEL suppliers.

Published: February 2019

The paper presents the analysis of dynamic behavior of the reinforced concrete containment of NPP unit under the combined effect of internal pressure shock caused by the accident in the reactor hall and seismic impact of design-basis earthquake using the finite element method (FEM) and DIPROS software. Using the modal analysis and numerical solution of the FEM equations of containment concrete, the stress-strain state of the building structure in the post-accident period was defined. It is shown that the maximum intensity of the stresses in the steel liner of the containment does not exceed the yield strength of the steel liner material. Accordingly, the liner integrity is preserved, the containment remains operable and ensures compliance of radiation safety requirements.

Authors: Iarmosh I. , Olkhovyk Yu.
Published: February 2019

For development of the management strategy for radioactive waste to be placed in near-surface disposal facilities (NSDF), it is necessary to justify long-term safety of such facilities. Use of mathematical modelling methods for long-term forecasts of radwaste radiation impacts and assessment of radiation risks from radionuclides migration can help to resolve this issue. The purpose of the research was to develop the conceptual model for determining the maximum activity of radwaste to be safely disposed in the NSDF and to test it in the case of Lot 3 Vector NSDF (Chornobyl exclusion zone). This paper describes an approach to the development of such a model. The conceptual model of 90Sr migration from Lot 3 through aeration zone and aquifer soils was developed. The results of modelling are shown. The proposals on further steps for the model improvement were developed.

Risk-Informed Approach to Structure Integrity Prediction and Optimization of In-Service Inspection of Heat Exchange Equipment with High Defect Statistics
Authors: Zarazovskii M. , Borodii M. , Kozlov V.
Published: February 2019

A physically and statistically based approach to steam generator heat exchange tube integrity assessment is proposed in the paper. The method is based on stochastic laws of crack dimensions distribution taking into account their growth, limit load model of cracked tube and SG plugging statistics. Based on the history of plugging tubes of specific SG, three statistical parameters have to be found: initial number of defects, initial defect size and defect growth rate. The developed method was used to predict HET failure for all Ukrainian SGs and to justify pressure reduction of hydrostatic test (HT) for primary side of NPPs with VVER. It is shown that pressure reduction does not practically increase the fracture probability during operation.

Published: February 2019

In accordance with global practice and a number of existing regulations, the use of conservative approach is required for the calculations related to nuclear safety assessment of NPP. It implies the need to consider the determination of neutron fluence errors that is rather complicated. It is proposed to carry out the consideration by the way of multiplying the neutron fluences obtained with transport calculations by safety factors. The safety factor values are calculated by the developed technique based on the theory of errors, features of the neutron transport calculation code and the results obtained with the code. It is shown that the safety factor value is equal 1.18 with the confidence level of not less than 0.95 for the majority of VVER-1000 reactor places where neutron fluences are determined by MCPV code, and its maximum value is 1.25.
