دور رأس المال الفكري في تعزيز الأداء المالي لعينة من الشركات المساهمة في سوق العراق للأوراق المالية
Authors: كاظم فائق جواد 
Published: April 2020

ان الاهتمام براس المال الفكري وتنميته ضرورة حضارية تفرضها متطلبات العصر ولايمكن تصور مجتمع متقدم في امكانياته الإنتاجية فقيراً في كفاءة راس المال البشري.
وتمتاز بيئة العمل بالتغير بصوره دائمة مما يضع ادارة الشركات المالية امام تحد دائم باتجاه التكيف مع المستجدات في هذه البيئة المتغيرة وهذا لايتم الا اذا امتلكت هذه الشركات الموارد البشرية المؤهلة وتوفير ثقافه منظميه لها، الأمر الذي تجلت معه مشكلة البحث بالتساؤلين الآتيين:
1- هل لرأس المال الفكري قيمة مالية محددة يمكن قياسها كمياً باستعمال البيانات الخاصة بالأوضاع المالية للشركات ومعطيات بيئة أسواقها المالية؟
2- هل تفسر قيمة رأس المال الفكري في حال قياسها تباين ربحية الشركات بوصفها أحد أبعاد الأداء المالي فيها؟
يهدف البحث الى التقصي للعلاقة بين قيمة رأس المال الفكري وربحية عدد من الشركات العراقية المساهمة المدرجة في سوق العراق للأوراق المالية والتحقيق في طبيعة تلك العلاقة قوة واتجاه.
وقد شملت عينة البحث (30) شركة من مجموع الشركات العراقية المساهمة المدرجة في سوق العراق للأوراق المالية والبالغ عددها (73) شركة عام 2012.
وتحددت ابرز نتائج البحث بصلاحية أنموذج الاختبار في تفسير العلاقة بين قيمة رأس المال الفكري والأداء المالي للشركات المدروسة عينة البحث بالتركيز على ربحيتها والتنبؤ باتجاهاتها المستقبلية المتوقعة بعدما أثبتته نتائج الانحدار من معنوية إحصائية بين المتغيرات المدروسة في ظل تكرار عملية الاختبار نظراً لتعدد قياسات الربحية عبر استعمال مقياسي العائد على الموجودات والعائد على حق الملكية، ومن ثم الاتجاه الطردي المشفوع بقوة العلاقة بين المتغيرين المدروسين. أما بخصوص توصيات البحث، فقد برزت من بينها ضرورة التحقيق في مسألة ما إذا كان بالإمكان إجراء دراسات مستقبلية تركز على دراسة كل مكون من مكونات رأس المال الفكري، منفرداً ومجتمعاً، في الأداء المالي ومن ثم معرفة المكون الأكثر تأثيراً في ذلك.

Published: April 2020

يبرز هدف هذه الدراسة هو بيان واقع القطاع التجاري للعراق ومحاولة التطرق نحو الفرص المتاحة للنهوض بهذا القطاع من خلال الكشف عن المعوقات ذات التأثير السلبي على الميزان التجاري، حيث تكمن مشكلة البحث مما يعاني منه القطاع التجاري في العراق من تردي جانب الصادرات وأقتصاره على قطاع واحد وهو القطاع النفطي دون القطاعات الأخرى وبالمقابل زيادة جانب الأستيرادات السلعية الأستهلاكية بشكل كبير ومن ثم أغراق السوق المحلية بها .
وتبرز أهمية البحث من خلال التعرف على أهم المعرقلات الأساسية التي تواجه القطاع التجاري في العراق وكيفية النهوض به من خلال أتباع سياسات تصديرية وأستيرادية رشيدة وكيفية الحد من أرتفاع أسعار السلع المحلية من خلال تخفيض تكاليف الأنتاج والحد من الاستيرادات الخارجية، حيث توصل الباحث الى أهم استنتاج عدم قدرة الصناعات المحلية على الاستمرار بالإنتاج والمنافسة في الاسواق المحلية فضلاً عن الاسواق الخارجية فضلا عن سوء توزيع وأستخدام المواد المالية المتأتية من تصدير النفط الخام الى جانب عدم وجود أستراتيجية واضحة لرفع جودة وكفاءة القطاعات الصناعية والزراعية عن طريق هذه الموارد المالية مما أنشأ عنها انكشاف أقتصادي للعالم الخارجي، ويوصي الباحث، تشريع وتنفيذ قانون التعريفة الكمركية وتحقيق العدالة في تحمل العبء الضريبي وضرورة وضع خطط نحو أستغلال العوائد النفطية بصورة مركزة لغرض ألاستثمار في القطاعات الغير نفطية (الصناعية والزراعية) ورفع قدرتها الانتاجية من حيث الجودة والقدرة التنافسية وأنتاج ما يمكن أنتاجه في الداخل والحد من أستيراده.

Geological and Geophysical Observations to Determine the Gas Seepage Source of Titas Gas Field Region, Bangladesh
Authors: Bijoy Sourov Datta , Gazi Md Yousuf , Kabir SM Mainul , Imam Badrul 
Published: April 2020

Titas Gas Field, the largest gas field in Bangladesh, has been encountering gas seepages in numerous points at the surface in an area of about 7 sq. km. at the southeastern part of the field since 2006. Gas has been seeping through the water wells, small and large holes in the fields including agricultural lands, in the river and through the cracks in the ground. The present research attempts to point out the source of the gas seepages based on the field studies, wireline log analyses and other available borehole data. A reconnaissance resistivity survey has been carried out around the high seepages area to detect any evidence of shallow subsurface fault. No fault was detected by resistivity survey in the shallow depth in the seepage area and thus fault as a conduit for the seepage could not be confirmed. Primarily, all wells of Titas Well Location (TWL-C) (Titas-06, 08, 09 and 10) were suspected as possible source wells as the surface distribution of seepages generally clusters around TWL-C. Titas-06 and Titas-08 were taken out of suspect list as the gas seepage distributions do not follow well path and cement bonding against reservoir sands including ‘A’ sand in these two wells are also good. Gas seepages follow the well trajectories of Titas-09 and 10 wells but cement bonding against ‘A’ gas sand in Titas-09 also discarded the well as a probable source of the gas seepage. Also, the suggestion that Titas well-03 could be a source of gas seep is also ruled out because of the fact that it is located 3 km away from the seepage area, there is no evidence of any seepage in between the well 3 and the seepage area, and the gas sands are also well protected. The above evidences turned the whole focus onto Titas-10. Gamma ray, resistivity, density, sonic and neutron log signatures recorded initially in the Titas-10 well strongly indicated a major gas sand and has been designated ‘A1’ gas sand. On the basis of various logs including CBL/VDL log it is evident that about 23 meters (3157-3180-meter MD) gas sand at the top which is not protected by cement. It is most likely source of gas seeps in Titas gas field is the gap in the cement protection at the top of A sand in Titas-10 well.

Estimation of Carbon Stock in the Peat Soils of Bangladesh
Authors: Uddin MJ , Mohiuddin ASM 
Published: April 2020

There are a very few study on the estimation of carbon stocks in the peat soils of Bangladesh. There are three categories of peat soils in Bangladesh: Sapric peat, Hemic peat and Fibric peat. A study was conducted in these three kinds of peat soils at 100 cm depths regarding their stock. The study shows that the carbon in peat soils is about 0.12 Pg whereas it was about 0.25 Pg during 1970s. So, it was found that soil organic carbon loss is alarming and it has been reduced by half during 50 years of agricultural intensification in Bangladesh. These peat soils are losing their carbon due to the decrease of inundation level by climate change, intensive agricultural use and even fuel use for cooking purposes by the local stakeholders. So, it is very much urgent to take steps in preserving the peat soils of Bangladesh.

Incorporation of Sequence Stratigraphy in Gas Reservoir Correlation: A Case Study
Authors: Parvin Afroza , Woobaidullah ASM 
Published: April 2020

The application of sequence stratigraphy to resolve the miscorrelation between different genetic units in reservoir characterization in a gas field of Surma Basin is dealt with. Interpretation of available seismic and wireline logs (gamma ray, resistivity, density and neutron porosity) give the sequence stratigraphic correlation of reservoir sands. The reservoirs geometry, its extent, seal architecture and trapping styles have been revealed better with this correlation. There is juxtaposition of two reservoir sands, namely A1 and A2. A1 is located at older highstand sand, whereas A2 is in the younger lowstand sand. Lithostratigraphically they might be same but sequences stratigraphy reveals that they are different and deposited at different times. Moreover, the concept reveals that lowstand sand has better reservoir quality than any highstand and transgressive sand.

Authors: Hasan Mahmud , Haque Md Inja Mamun , Akter Nafia , Rahman Mohammad Shamsur , Eti Afroza Sultana 
Published: April 2020

The effects of three wetting media (cattle blood, rice gruel and subsurface clean water) of the culture media ingredients (a mixture of mustard oil cake, soybean meal and mud) on the yield and amino acid composition of tubificid worms cultured on a pilot scale in a fish farm for 42 days were evaluated. The worm yields were in the order: cattle blood wetted media (683.68 ± 3.86 mg/cm2), rice gruel (615.63 ± 3.66 mg/cm2), water (584. 38 ± 1.41 mg/cm2). Lysine, arginine and leucine were the most prevalent of the eight essential amino acids in worms cultured in the media wetted in cattle blood medium. The results suggested that a mixture of 40% mustard oil cake, 30% soybean meal and 30% mud can be used for the commercial culture of tubificid worms as live fish food. The tubificid worms showed high level of amino acids suitable for fish that require a high content of dietary amino acids.

Authors: Saha Shukanta , Begum Hasna Hena , Nasrin Shamima 
Published: April 2020

A pot experiment was conducted to study the effect of drought stress on growth and accumulation of proline in five rice varieties namely BRRI dhan-30, BRRI dhan-32, BRRI dhan-34, BRRI dhan-38 and BRRI dhan-56 and to characterize them on the basis of their behavior of drought tolerance. Drought stress caused the decrease of growth like root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, the ratio of root-shoot length. Among the rice varieties, BRRI dhan-56 showed the lowest decrease of growth of plant. BRRI dhan-56 showed the least decrease of water content in both root and shoot. On the other hand, the accumulation of proline was increased in five rice varieties under stress. BRRI dhan-56 showed the highest (3.7- folds) increase in the accumulation of proline in leaf under stress. This study suggests that BRRI dhan-56 may possess drought tolerance characteristics while BRRI dhan-30, BRRI dhan-32, BRRI dhan-34 and BRRI dhan-38 may be drought sensitive based on their growth and proline accumulation behavior.

Authors: Sandu Aurelia Mihaela , Fürtös Adrian Mircea , Gorgan Radu Mircea 
Published: April 2020

Introduction: Brain vascular pathology, aneurysms, arteriovenous malformations (AVMs), cavernomas, dural arteriovenous fistulas (DAVF), venous angiomas and capillary telangiectasia, represents a serious health problem worldwide.
Aim: The aim of this article is to perform an analysis of patients with brain vascular pathology and to analyze costs of health services, a research market for an entrepreneurial project, in order to design guidelines for patients’ selection and treatment.
Material and methods: We performed an observational, descriptive study of patients with vascular pathology, from 2018 to 2019.
Results: A total of 153 patients with brain vascular pathology were admitted in our department. Mean age was 49.53 ± 13.997 years. Sex ratio was 0.86. Mean hospital stay was 11.33 ± 13.724 days. Seventy-four patients (48.37%) underwent surgery. Seventy-eight patients (50.98%) had cerebral aneurysms. Complications were seen in 24 patients (30.77%) and vasospasm in 32 cases (41.03%). Thirty-six patients underwent surgery. Outcome was favorable, according to mRS(p=0.001) and Karnofsky score(p=0.006).Thirty-three patients (21.57%) had brain AVMs. Twenty patients underwent surgery. Complications were seen in 4 cases (12.12%). The outcome was favourable, according to mRS(p=0.001) and Karnofsky score (p=0.002). Thirty-nine patients (25.49%) had cavernomas. Surgery was performed in 18 cases. The outcome was favourable, according to Engel Epilepsy Surgery Outcome Scale, mRS (p=0.000) and Karnofsky score (p =0.000). Costs of health services were correlated with longer hospitalization, higher mRS, lower Karnosfsky score, presence of complications and presence of vasospasm.
Conclusions: Proper treatment of brain vascular pathology ensures a favourable outcome. Adequate patients’ selection and choosing the best treatment can reduce costs. Surgery is the treatment of choice in ruptured aneurysms, AVMs and cavernomas. Early surgery, with specific treatment of the vascular lesion and removal of intracranial blood ensures a better outcome, with lower medical costs. Prevention of complications, aggressive treatment of vasospasm reduces medical costs.

Authors: Bălașa Adrian , Hurghiș Corina-Ionela , Tămaș Flaviu , Florian Ioan-Alexandru , Peter Levente , Chinezu Rareș 
Published: April 2020

Aim: Pedicle screw fixation is an established technique in the lumbar and thoracic area. Fluoroscopy-guided screw placement and subsequently navigation have decreased the rate of misplaced screws, but no technique has wholly eliminated this risk. This paper aims to study the difference between the accuracy of the fluoroscopic guided screw placement to that of the 2D fluoroscopy- preop CT fused neuronavigation guided technique, a lesser-used navigation technique.
Material and Methods: This retrospective study reflects our results using both techniques between March 2018 and March 2019 in both degenerative or traumatic spinal pathology for thoracic and lumbar regions. The accuracy of the screw placement was measured using Mirza grading system on postoperative CT images.
Results: A total number of 56 patients underwent spinal instrumentation surgery. A total of 274 screws were placed with a mean number of 4.89 screws per patient; 199 screws were implanted using neuronavigation and 75 using the freehand-2D fluoroscopy-guided technique. The accuracy rate of pedicle screw placement in the freehand technique guided by 2D fluoroscopy was 88,00%. With the use of neuronavigation, the accuracy increased to 89,96%.
Conclusion: Pedicle screw placement accuracy is higher when guided by CT-fluoro matching neuronavigation compared to freehand fluoroscopy-guided technique and can be used in departments where there is no intraoperative O-arm or 3D fluoroscopy available.
