Authors: Tang YiWen , Che XiaoTian , Wang Yao Lei , Ye Xin , Cao Wan Li , Wang Yi 
Published: April 2022

AimWe performed a comparative study to investigate the efficacy of closed system transfer devices (CSTDs) on the safe handling of injectable hazardous drugs (HDs).MethodsThe exposure assessments of cyclophosphamide and cytarabine were performed under traditional or CSTDs. For preparation activity, chemotherapy contamination samples on protective equipment (such as gloves and masks) were collected. The contamination analysis was performed by liquid chromatography with tandem mass spectrometry (LC-MS/MS). A 6-item form was distributed monthly (form M1–M6, total 6 months) to assess the pharmacists' experience on ergonomics, encumbrance, and safety impression.ResultsTotally, 96 wiping samples were collected throughout the study. The numbers of contaminated cyclophosphamide samples reduced under CSTD were −37.8, −41.6, −67.7, −47.3, and −22.9% and cytarabine were −12.3, −12.1, −20.6, −69.6, and −56.7% for left countertop, right countertop, medial glass, air-intake vent and door handle, as compared to traditional devices. The reduction was similar to pharmacist devices, i.e., −48.2 and −50.0% for masks and gloves cyclophosphamide contamination, −18.0 and −42.4% for cytarabine. This novel system could improve contamination on dispensing table, transfer container, and dispensing basket by −16.6, −6.0, and −22.3% for cyclophosphamide and −28.5, −22.5, and −46.2% for cytarabine. A high level of satisfaction was consistently associated with ergonomics for CSTD during the compounding process. Meanwhile, a slightly decreased satisfaction on ergonomics, encumbrance, and safety impression was observed for the traditional system between M2 and M3.ConclusionClosed system transfer devices are offering progressively more effective alternatives to traditional ones and consequently decrease chemotherapy exposure risk on isolator surfaces.

Published: April 2022

IntroductionSystematic evaluation of the quality of services provided in hospitals and healthcare centers is the first step toward standardization and improving their quality.MethodsIn this systematic review (meta-analysis) study, the information was collected by searching for the articles published in well-known Iranian and international and through searching for the keywords of SERVQUAL, services quality, gap, hospital, patients, Iran, and without language and time restrictions.ResultsA total of 18 articles were reviewed and opinions of 4,714 people who referred to hospitals and healthcare centers affiliated to Iran University of Medical Sciences during the past 10 years from 2010 to 2019 were examined in this study. The results showed that there was a quality gap in all 5 dimensions between the current status and desirable status of patients and based on a maximum score of 5, responsiveness (1.04), and assurance (0.99), empathy (0.95), reliability (0.91), and physical or tangible factors (0.86) were ranked first to fifth, respectively. According to the random effect model, the mean score of patients' perceptions and expectations and the gap between them was 3.59 (CI 95%: 3.73, 3.46), 4.66 (CI 95%: 4.33 and 4.66), and 0.86 (CI 95%: 1.00, 0.72), respectively.ConclusionThe patients' expectations in university hospitals were higher than their perceptions. Therefore, it is recommended for Ministry of Health and Medical Education of Iran to monitor periodically the quality of hospitals while focusing on students' and patients' satisfaction and pay attention to dimensions that have the highest quality gap.Systematic Review Registrationhttps://ethics.research.ac.ir/ProposalCertificateEn.php?id=167856&amp;Print=true&amp;NoPrintHeader=true&amp;NoPrintFooter=true&amp;NoPrintPageBorder=true&amp;LetterPrint=true, identifier: IR.AJUMS.REC.1399.747.

Published: April 2022

ObjectivePrimary central nervous system lymphomas (PCNS) are relatively rare tumors, accounting for about 4% of all brain tumors. On neuroimaging, they are characterized by a low MR signal in T1, isointense in T2, bright uniform contrast enhancement, and diffusion restriction. The aim of this study is to note the lack of effectiveness of the MR/CT perfusion technique in complex multiparametric imaging in the differential diagnosis of primary lymphomas of the central nervous system in comparison with highly malignant gliomas and brain metastases.Materials and MethodsThis prospective study included 80 patients with CNS tumors examined/operated at the Federal Center for Neurosurgery (Tyumen, Russia) from 2018 to 2021. The patients were divided into 4 groups: group 1 consisted of 33 cases with primary CNS lymphomas (10 cases with atypical manifestations according to perfusion parameters and 23 cases of classic CNS lymphomas), group 2 with anaplastic astrocytomas—14 cases, group 3—23 cases with glioblastomas and group 4—10 cases with solitary metastatic lesions. The study was carried out on a General Electric Discovery W750 3T magnetic resonance tomograph, a Canon Aquilion One multispiral X-ray computed tomograph (Gadovist 7.5 ml, Yomeron 400 mg−50 ml). Additionally, immunohistochemical analysis was carried out with the following markers: CD3, CD20, CD34, Ki-67, VEGF.ResultsIt has been established that MR/CT perfusion is not a highly sensitive method for visualizing primary CNS lymphomas, as previously thought, but at the same time, the method has a number of undeniable advantages that make it indispensable in the algorithm of a complex multiparametric diagnostic approach for this type of tumor. Nevertheless, PLCNS is characterized by an atypical manifestation, which is an exception to the rule.ConclusionsThe possibilities of neuroimaging of primary lymphomas, even with the use of improved techniques for collecting MR/CT data, are limited and do not always allow reliable differentiation from other neoplasms.

The problem faced by the wood processing industry in Indonesia today is the shortage of wood raw materials. This occurs because the speed at which timber is used is not balance with the speed at which new stands are build. Meanwhile, the need for wood for furniture, building materials and other needs continues to increase in line with population growth. Therefore, it is necessary to find alternative raw materials for the wood processing industry. Bamboo is one material that can be use for this purpose. Bamboo is a long fiber and has advantages in terms of the harvest period, namely within 3-4 years it can be harvested, shorter than 8-20 years for fast-growing timber species. In this research, a combination of fiber and laminate boards with epoxy adhesive. The material used is the type of betung bamboo (Dendrocalamus asper) and then tested on the combination of fiber and laminated bamboo boards there are 3 tests, namely fracture strength, absorption capacity and density. The results of this research indicate that from the treatment of 255g adhesive and 127.5g of fiber has a higher average compared to 127.5g of adhesive and 255g of fiber. From the test results, the combination of fiberboards and laminate boards as HDF (Hard Dencity Fiberboard) classified which can be used for materials for making adhesive walls, ceilings, pinyi and containers. However, in contrast to the 127.5g adhesive and 255g fiber treatment included in the MDF (Medium Dencity fiberboard) classification, furniture such as household appliances, molding, window frames, door skins and car dashboards are used.

According to previous observations, the distribution of habitat and population of slow lorises in Indonesia shows that slow lorises are found mostly in plantation habitats, agricultural land, and community forests where the available feed supply is in the form of fruits, insects and small reptiles. Taman Buru Masigit Kareumbi is one of the areas that has a level of vulnerability to the illegal hunting of slow lorises outside the forest area that enters the community land area. One of the habitats for the Javan slow loris is the Masigit Kareumbi Hunting Park (TBMK). Observations in the study used the line transect method (line transect) combined with the spot lighting method and GPS mapping, with a sampling intensity of 1% in accordance with P.67 /Menhut-II / 2016 regarding criteria and forest inventory standards for sampling intensity. The survey was carried out by walking slowly at an average speed of 1 km / hour and systematically looking for and observing the presence of slow lorises on the forest floor, lower canopy, middle canopy and upper canopy. The existence of slow lorises in Taman Buru Masigit kareumbi is spread across utilization blocks in 3 locations, namely Bagus, Hadun, and Cimulu, and 5 Javan slow lorises were found directly in the field during the research.

Introduction. Oxidative stress is one of the important causes of red blood cells (RBCs) storage lesion. As a hormone, melatonin (MT) is also an effective antioxidant, however the pro- and antioxidative properties of MT depend on the cell type, redox state, as well as experimental conditions.Aim of this study — to investigate the protective effects of low concentration of MT on the stored RBCs in vitro.Materials and methods. Leukofi ltered RBCs were incubated in MAP RBC additive solution with or without 150 pg/mL of MT for 42 days under blood bank conditions. The morphology, aggregation index, methemoglobin (MetHb), m alondialdehyde (MDA), glucose, lactic acid and ATP of RBCs were detected on days 0, 7, 14, 21, 28, 35 and 42 to observe the protective effects of MT during the storage of RBCs.Results. During RBCs s torage, the number of deformed RBCs, relative hemolysis rate, aggregation index, MDA and MetHb were signifi cantly affected by both storage time (p < 0.0001) and melatonin (p < 0.01), and they had interaction only on the number of deformed RBCs (p < 0.0001). The concentration of glucose, lactic acid and ATP were affected by storage time (p < 0.0001), but not by MT concentration (p > 0.05). The number of deformed RBCs, relative hemolysis rate, MDA and MetHb in MT group were signifi cantly lower than that in control group at the end of storage stage (p < 0.05).Conclusion. Our study showed low hypnotic drug concentration of MT is speculated to have protective effects on the quality of stored RBCs through antioxidative mechanism.
Substantiation of the diameters of pipelines of water supply and wastewater disposal systems based on minimizing the costs of their life cycle

Published: April 2022

При проектировании городских систем водоснабжения и водоотведения требуется обосновать диаметр трубопроводов, скорость движения воды и стоков. Существующие подходы и нормативные требования, изложенные в СП 31.13330.2012, базируются в том числе на экономических показателях, вычисляемых на основе приведенных затрат в строительство и эксплуатацию систем водоснабжения и водоотведения. Вместе с тем, согласно ГОСТ Р 587885-2019, выбор проектного варианта следует осуществлять на основе затрат жизненного цикла этих систем. Предлагается методика вычисления оптимальных значений диаметров труб и скорости движения воды и сточной жидкости в трубопроводах на основе затрат их жизненного цикла. Проведенные численные эксперименты показали, что оптимальные значения скорости зависят от величины расхода воды и сточной жидкости, стоимости электроэнергии и количества лет жизненного цикла систем водоснабжения и водоотведения. Предлагаются новые формулы вычисления экономически обоснованных значений скорости движения воды и стоков для стальных, чугунных и полиэтиленовых труб.
While designing urban water supply and wastewater disposal systems, substantiating the diameter of pipelines, the flow rate of water and wastewater is required. The existing approaches and regulatory requirements set forth in CP 31.13330.2012 are based, among other things, on the economic indicators calculated on the basis of the overhead costs for the construction and operation of water supply and wastewater disposal systems. At the same time, according to GOST R 587885-2019, the choice of a design option should be based on the life cycle costs of these systems. A method is proposed for calculating the optimal values of pipe diameters and the velocity of water and waste liquid in pipelines based on the costs of their life cycle. The conducted numerical experiments showed that the optimal values of the velocity depend on the flow rate of water and waste liquid, the cost of electricity and the number of years of the life cycle of water supply and wastewater disposal systems. New formulas are proposed for calculating economically justified values of the velocity of water and wastewater for steel, cast iron and polyethylene pipes.

خطاب الملأ في القرآن الكريم: قراءة في ضوء النقد الثقافي ونظرية الحجاج
Authors: الناصر دعد 
Published: April 2022

امتلك الملأ في القرآن الكريم سلطة الحكي، ولكنه لم يمتلك سلطة الحجة الظاهرة، فانطلق بإيعاز من نفوذه المادي ولغايات الحفاظ عليه يحاجج الأنبياء –عليهم السلام- وأتباعهم، فكان حجاجا مراوغا تقنَّع بالصلاح وإرادة الإصلاح، ودرء المفاسد التي ستتجرعها المجتمعات جرَّاء الدعوات النبوية "الطارئة"، مع أنه استبطن إرادة خفية تصارع الأنبياء الذين هدّدت رسالاتهم الشريفة سلطانهم الدنيوي، ونيّاتهم النفعية.
ستجيب هذه القراءة عن سؤالها المركزي: كيف تجلى النسق الظاهر المقنَّع، والباطن الخفي في الآيات التي نقلت خطاب الملأ؟ هذا الخطاب الذي سيكون ميدان التطبيق، وبمنهجية النقد الثقافي/ النسقي المشتغل أساسا على فضح الحيل الثقافية وأساليبها المقنّعة، وإذ جوَّز هذا النقد الثقافي استثماره المدارس والمناهج النقدية وصولا لغاياته، وإتقانا لحفرياته المعرفية، فقد اتكأت القراءة على الحقل اللساني ونظرية الحجاج لتبرز الخواء العقلاني الذي تميز به الملأ في صراعهم مع الأنبياء، الأمر الذي أفضى بهم إلى المخاتلة والإيهام في كلّ خطاباتهم الممتدة في فضاءات عديدة، حتى لكأنها خطاب واحد، وهو الخطاب الذي انهزم أخيرا على الصعيدين الفكري العقدي، والمادي الحضاري.

Published: April 2022

Untuk mengetahui adakah pengaruh pembelajaran online pada masa pandemi terhadap sikap belajar siswa di MAN 1 Mandailing Natal. Penelitian dilakukan karena penulis menemukan permasalahan dalam proses pembelajaran TIK diantaranya siswa tidak memperhatikan guru, sikap belajar siswa saat belajar kurang baik, dan kurangnya keinginan siswa untuk mengetahui tentang pembelajaran TIK disebabkan oleh kurangnya fasilitas untuk mengenal alat-alat yang ada pada pelajaran TIK. Penelitian ini menggunakan metode kuantitatif dengan korelasi dan pengolahan data menggunakan SPSS. Populasi dalam penelitian ini adalah seluruh siswa kelas X MIA-3, MIA-4, Mia-5 yang berjumlah 107 siswa, sedangkan sampel diambil melalui teknik proportional random sampling dengan jumlah 44 siswa. Instrumen yang digunakan adalah angket/angket dengan skala likert. Hasil uji validitas angket dinyatakan valid dengan nilai sig. (2-tailed) masing-masing variabel X dan variabel Y adalah < 0,005. Hasil pengujian reliabel dilihat dari nilai rhitung dan rtabel diperoleh nilai rhitung > rtabel. Nilai rtabel sebesar 0,297 diperoleh dari nilai N 44 = angka 44 memiliki nilai rtabel sebesar 0,297. Hasil uji reliabilitas dapat diketahui bahwa secara keseluruhan variabel X dan Y memiliki nilai cronbach's alpha > 0,06. Variabel X memiliki nilai 0,854, variabel Y dengan nilai 0,902, sehingga dikatakan reliabel. Hasil penelitian menunjukkan bahwa pembelajaran online berpengaruh terhadap sikap belajar siswa sebesar 70% dan nilai korelasi sebesar 84,1%. Pengaruh yang diberikan adalah cukup baik, meskipun di masa pandemi COVID-19 siswa tidak bersikap negatif selama proses belajar online berlangsung dan saat berinteraksi di luar pembelajaran Sikap siswa juga cukup baik. Karena guru selalu mengontrol siswa selama pembelajaran berlangsung dan siswa juga masih di bawah pengawasan orang tua sehingga saat belajar beberapa siswa ada yang mendampingi baik orang tua maupun saudara.

meantime to return to work following percutaneous transpedicular fixation versus open pedicle screw fixation. We evaluated the average time required to return to work following percutaneous transpedicular fixation versus open pedicle screw fixation in traumatic lumbar spine injury.
Material and Methods: A randomized controlled trial included 60 patients. At study entry baseline demographics (age, gender, & duration of injury) were recorded. 30 patients were in the percutaneous transpedicular fixation group (A), while 30 patients were in the open pedicle screw fixation group (B). All the patients were followed every month time taken to return to work (TTRW) was noted on a proforma.
Results: Mean time taken by patients to return to work after surgery in Group A was 2.9 days, while in group B it was 5.1 days in group B. The difference between the two groups was significant (p-value 0.001). Within Group A, male and female genders showed a significant difference (p-value 0.032) in the TTRW after surgery. However, Group B did not show a similar difference between male and female patients. Duration of procedure had a significant effect on the TTRW (p-value 0.001).
Conclusion: We found ‘ time is taken to return to work’ was 2.93 ± 0.82 in group A and 5.10 ± 0.71 in group B (P-value 0.001). There was a significant difference in both groups. Percutaneous transpedicular fixation is a fast, safe and effective method as compared to other methods.
