Authors: Erkmen Turhan , Günsel Ayşe , Altındağ Erkut
Published: May 2020

Information Technologies (IT) and IT-based capabilities represent a sovereign approach to firm survival and success in today’s business environment. The reflections of information technologies on company performance has always been a controversial topic in the management literature. As previous studies examining these kinds of relationships reported mixed results in terms of information technologies efficiency paradox, scholars are still trying to specify the underlying mechanisms and organizational factors linking IT to financial performance. Building on the resource-based view and positioning theory, this paper focuses on sustainable IT capabilities to generate value from IT investments. Moreover, the conflicting results regarding the effects of IT on firm performance lead to questions such as what sort of organizational contexts influence IT usage and enable firms to achieve business goals. This study considers IT capability as a three-dimensional construct—managerial IT capability, technical IT capability, and human support—and investigates the effects of sustainable IT capability on firm performance as well as analyzing the moderating effect of innovative climate. By studying the data from 221 managers of IT companies listed in the top 500 list of Information and Communication Technologies Authority (ICTA), we found that: (1) managerial and technical IT capabilities have significant and positive effects on quantitative performance, all aspects of IT capability—managerial IT capability, technical IT capability, and human support—are significantly and positively associated with qualitative performance, and (2) the relationship between technical IT capability and quantitative performance becomes stronger when the organizational climate is more innovation-oriented. (3) Similarly, the relationship between managerial and technical IT capabilities and qualitative performance becomes even stronger when the organizational climate is more innovative. The study concludes with a discussion of the theoretical and managerial implications.
Reconstruction or Reuse? How Real Estate Values and Planning Choices Impact Urban Redevelopment
Authors: Mangialardo Alessia , Micelli Ezio
Published: May 2020

Local administrators and private investors rely on various urban redevelopment strategies, the choice of which depends on the economic expectations of property owners and investors. Some of these options foresee replacing obsolete buildings with new constructions; others prefer the reuse of existing assets. This study examines the conditions that make these different strategies feasible, bringing to light the aspects that favor demolition and reconstruction processes over interventions based on the redevelopment of existing assets. The analysis focuses on the variables that determine the choice between these two options. The model that has been developed highlights, on one hand, the role of urban planning tools and urban densification and, on the other, the relationship between the land market and the value of existing assets. The model has been tested on five cities in northern Italy, which fall into three territorial categories—large metropolitan cities, medium-sized cities, and cities of limited rank—to test how different social and economic contexts affect the feasibility of the strategies we evaluated. The results of the study underscore the extent to which the demolition and reconstruction of existing assets is only viable in certain limited areas and under particular market and settlement conditions. While large metropolitan areas seem to have the option of radically replacing existing real estate assets, medium-sized cities and especially small cities are constrained in redeveloping existing urban assets and must forego demolition and reconstruction projects, which do not prove to be economically feasible.

Published: May 2020

The rapid growth of Information and Communication Technologies (ICT)—specifically, the Internet—has given emergence to e-learning. Resultantly, web-based e-learning systems are being increasingly developed to enhance the learning process. However, the utilization of such systems is low, mainly owing to poor quality content and overall design problems. To improve usage, it is imperative to identify the factors with the most significant impact on the quality of these systems so that the e-learning industry keeps these factors in consideration while developing e-learning systems. This study focused on the identification and prioritization of factors related to the design quality of e-learning systems through a hierarchical quality model. Thus, firstly, an extensive literature review was conducted to identify the factors that most affect the quality of web-based e-learning systems. Secondly, among the identified factors, only those with the most significant effect were considered. To identify the most important quality criteria, a survey was conducted. An instrument was deployed among 157 subjects, including e-learning designers, developers, students, teachers, and educational administrators. Finally, a second instrument was distributed among 51 participants to make a pairwise comparison among the criteria and rank them according to their relative importance. The identified and prioritized factors were classified into four main categories. Among these four factors, content was identified as the most important factor, whereas design was found to be the least important factor.
Prospective Analysis of Levels and Correlates of Physical Activity during COVID-19 Pandemic and Imposed Rules of Social Distancing; Gender Specific Study among Adolescents from Southern Croatia
Authors: Sekulic Damir , Blazevic Mateo , Gilic Barbara , Kvesic Ivan , Zenic Natasa
Published: May 2020

Background: Due to the COVID-19 pandemic, global authorities have imposed rules of social distancing that directly influence overall physical activity in populations. The aim of this study was to evaluate the trends of changes in physical-activity levels (PALs) in adolescents and factors that may be associated with PALs among the studied boys and girls. Methods: Participants in this prospective study comprised 388 adolescents (126 females; mean age: 16.4 ± 1.9 years) from southern Croatia who were tested at a baseline (before the imposed rules of social distancing) and at a follow-up measurement (three weeks after the initiation). Baseline testing included anthropometric variables, variables of fitness status (done at the beginning of the school year), and PALs. At the follow-up, participants were tested on PALs. PALs were evaluated over an online platform using the Physical Activity Questionnaire for Adolescents. Results: A significant decrease of PALs was evidenced for the total sample (t-test = 3.46, p < 0.001), which was primarily influenced by a significant decrease of PALs in boys (t-test = 5.15, p < 0.001). The fitness status (jumping capacity, abdominal strength, aerobic endurance, and anaerobic endurance) was systematically positively correlated with PALs at the baseline and follow-up among boys and girls, with the most evident association between aerobic and anaerobic endurance capacities and PALs. Correlations between anthropometric and fitness variables with changes in physical activity (e.g., the difference between baseline and follow-up PALs) were negligible. Conclusions: Differences in PAL changes between genders were probably related to the fact that PALs among boys were mostly related to participation in organized sports. Correlations between baseline fitness status and PALs indicated the importance of overall physical literacy in preserving PALs in challenging circumstances, such as the COVID-19 pandemic observed here.

Surfaces of implanted medical devices are highly susceptible to biofilm formation. Bacteria in biofilms are embedded in a self-produced extracellular matrix that inhibits the penetration of antibiotics and significantly contributes to the mechanical stability of the colonizing community which leads to an increase in morbidity and mortality rate in clinical settings. Therefore, new antibiofilm approaches and substances are urgently needed. In this paper, we test the efficacy of a broad-range recombinant endolysin of the coliphage LysECD7 against forming and mature biofilms. We used a strong biofilm producer—Klebsiella pneumoniae Ts 141-14 clinical isolate. In vitro investigation of the antibacterial activity was performed using the standard biofilm assay in microtiter plates. We optimized the implantable diffusion chamber approach in order to reach strong biofilm formation in vivo avoiding severe consequences of the pathogen for the animals and to obtain a well-reproducible model of implant-associated infection. Endolysin LysECD7 significantly reduced the biofilm formation and was capable of degrading the preformed biofilm in vitro. The animal trials on the preformed biofilms confirmed these results. Overall, our results show that LysECD7 is a promising substance against clinically relevant biofilms.

Mutations are incorporated into the genomes of RNA viruses at an optimal frequency and altering this precise frequency has been proposed as a strategy to create live-attenuated vaccines. However, determining the effect of specific mutations that alter fidelity has been difficult because of the rapid selection of the virus population during replication. By deleting residues of the structural polyprotein PE2 cleavage site, E3Δ56-59, in Venezuelan equine encephalitis virus (VEEV) TC-83 vaccine strain, non-infectious virus particles were used to assess the effect of single mutations on mutation frequency without the interference of selection that results from multiple replication cycles. Next-generation sequencing analysis revealed a significantly lower frequency of transversion mutations and overall mutation frequency for the fidelity mutants compared to VEEV TC-83 E3Δ56-59. We demonstrate that deletion of the PE2 cleavage site halts virus infection while making the virus particles available for downstream sequencing. The conservation of the site will allow the evaluation of suspected fidelity mutants across alphaviruses of medical importance.

Cattle are susceptible to infection with multiple serovars of pathogenic leptospires, resulting in abortion, stillbirth, premature birth, reproductive failure and milk drop syndrome. Cattle also act as a reservoir host for L. borgpetersenii serovar Hardjo which is excreted from renal tubules via urine into the environment where it persists in suitable moist conditions. Our previous work demonstrated that 7% of urine samples from beef cattle were positive for L. borgpetersenii serovar Hardjo by culture and/or the fluorescent antibody test (FAT). In this study, a real-time PCR (rtPCR) assay was applied to determine the relative performance of rtPCR based detection of L. borgpetersenii serovar Hardjo compared to previously reported culture and FAT techniques. Of 42 bovine urine samples positive for leptospires by culture and/or FAT, 60% (25/42) were positive by rtPCR. Of 22 culture-positive samples, 91% (20/22) were rtPCR-positive. Of 32 FAT-positive samples, 50% (16/32) were rtPCR-positive. For 10 samples that were culture-positive but FAT-negative, 90% (9/10) were rtPCR-positive. For 20 samples that were FAT-positive but culture-negative, 25% (5/20) were rtPCR-positive. Collectively, these results indicate that no single assay is optimal, and the use of more than one assay to detect leptospires in urine from naturally infected cattle is recommended.

As fraturas do úmero proximal (FUP) representam aproximadamente 5%, quando consideramos todas as fraturas. São lesões frequentes em idosos após trauma de baixa energia, em decorrência da prevalência de osteoporose. Sua incidência tem aumentado nos últimos anos, elevação esta atribuída ao envelhecimento da população. As principais complicações nos idosos são a lesão do manguito rotador (MR) e a osteonecrose da cabeça umeral, possíveis causas de dor e disfunção no ombro, perda da independência e, consequentemente, diminuição da qualidade de vida. Preservar a independência é o principal objetivo do tratamento proposto, considerando também o alívio da dor e a manutenção da função do ombro.

Authors: Al-Radi Osman
Published: May 2020

Background: Phrenic nerve injury and diaphragmatic dysfunction are common after pediatric cardiac surgery leading to failure to wean from ventilatory support. Diaphragmatic plication is the standard management of diaphragmatic paralysis. The aim of this retrospective study is to review our experience with diaphragmatic plication and its effect on the operative outcome.

Methods: This retrospective cohort study included all patients who underwent diaphragmatic plication from June 2010 to June 2017. Seventy-six patients (2.87%) had unilateral diaphragmatic paralysis following 2646 congenital cardiac procedures. Sixty-four patients (2.4%) underwent diaphragmatic plication.

Results: The median age for the patients who had plication was 2.75 months (range 0.5- 36) and 3.7 months (range 0.66 to 123) for non-plicated patients. Thirty-six were males (56.25%), and the most common procedure associated with diaphragmatic plication was modified Blalock Taussig Shunt (n= 13; 20.3%). Left-sided diaphragmatic plication was performed in 44 patients (68.7%). The mean time between the primary surgery and diaphragm plication was 6.42±4.51 days. The mean ventilation period before plication was 4.93±3.71 days, and post plication ventilation median time was 2.11±1.82 days. Two patients (3.1%) required tracheostomy for prolonged respiratory insufficiency. One patient (1.6%) needed surgical revision, and two patients (3.1%) had their diaphragmatic plication during the initial surgery.

Conclusion: Diaphragmatic plication is an effective procedure in the management of postoperative diaphragmatic paralysis. We recommend early plication for patients with symptomatic diaphragmatic paralysis causing prolonged ventilation

Residue number system (RNS) has emerged as a knocking field of research due to its high speed, fault tolerant, carry free and parallel characteristics. Due to these features it has got important role in high performance computing especially with reduced delay. There are various algorithms have been found as a result of the research with respect to RNS. Additionally, since RNS reduces word length due to the modular operations, its computations are faster compared to binary computations. But the major challenges are the selection of moduli sets for the forward (decimal to residue numbers) and reverse (residue numbers to decimal) conversion. RNS performance is purely depending on how efficiently an algorithm computes / chooses the moduli sets [1]-[6]. This paper proposes new method for selecting the moduli sets and its usage in cryptographic applications based on Schonhage modular factorization. The paper proposes six moduli sets {6qk1, 6qk+1, 6qk+3, 6qk+5, 6qk+7, 6qk+11} for the RNS conversions but the Schonhage moduli sets are expressed as the exponents that creates a large gap between the moduli’s computed. Hence, a new method is proposed to for computing moduli sets that helps in representing all the decomposed values approximately in the same range.

In underwater Wireless Sensor Networks (UWSN) the node mobility is higher as the nodes drift with the water so identifying the exact location of the nodes is a challenging task. Terrestrial WSN use Global Positioning System (GPS) to locate the nodes, but the same cannot be applied for UWSN as they do not propagate under water. Underwater uses acoustic channel for communication which suffers from low bandwidth, high propagation delay, high bit error rate, high node mobility and variable sound speed which makes localization a challenging task. Hence there is an evolving requirement for energy efficient localization algorithm. To overcome these problems we propose an Energy Efficient Cluster Based Localization Algorithm (EECBLA) to minimize the energy utilization and identify an accurate location of the sensor nodes. EECBLA is a cluster based localization protocol where the GPS enabled high power anchor nodes are utilized to estimate the location of the un localized sensor nodes. To improve the localization accuracy it is necessary to improve the network connectivity. Network connectivity can be improved by increasing the lifetime of the sensor nodes. EECBLA proposes an energy efficient localization scheme where the node operates in active and sleep mode to efficiently utilize the available energy. In this research work we take a sample example and demonstrate how the location is estimated through TOA and Euclidean distance. Accuracy of TOA is measured as 8.36, 4.76, 13.21, 14.85, 16.26 and 3.60. The average estimated localization error of EECBLA is around 4m to 6m. EECBLA localization error is compared with other localization algorithms like 3DUL whose average localization error is 5m to 10m, SDMA whose average localization error is around 24% and localization error of Hybrid RSS ranges from 4.69m to 15.85m. When compared with these methodologies there is a decrease in localization error by 3%, and the increase in accuracy by 5% in EECBLA protocol.

The current work expects to decide the attributes of compression of the (Magnesium composite) AZ 91E-Zro2-Fly Ash Hybrid Metal Matrix utilizing the conventional explanatory strategy and limited component technique. Fly ash and ZrO2 taken as equal weight proportions, composites are fabricated by means of a vortex method under the path of stir casting. The density and fracture toughness were found experimentally, the experimental density was decreased compare to the theoretical density, but the density is increased slightly for composites compare to the base material. The fracture toughness is decreased for composites compare to the base material; this is due to the improvement of the grains by adding strengthening molecules. The compressive strength was decreased by decreasing of the height of the deformation in percentage for base material and the composites of H/D 1.0 and 1.5. The compressive strength is high for the composites compare to the base material even the density of the composite is little bit high, hence suggested that composite system gives the better compressive strength results

Authors: El-Sheikh Sawsan , Eleiwa Naglaa , Nazim Heba
Published: May 2020

Objective: The present work was conducted to evaluate the possible renoprotective effect of both calcium acetate and quercetin against gentamicin-induced nephrotoxicity in rat. Design: Controlled study. Animals: Seven groups of male albino rats. Procedures: Seventy, apparently healthy, male albino rats were haphazardlydivided into seven equal groups. Group 1: injected I.P with normal saline (control), Group 2: received gentamicin (80 mg/kg/d, I.P for 7 consecutive days), Group 3: received gentamicin plus lower dose of calcium acetate (75 mg/kg/d, orally for 7 consecutive days) simultaneously, Group 4: received gentamicin plus higher dose of calcium acetate (200 mg/kg/d, orally for 7 consecutive days) simultaneously, Group 5: received gentamicin; afterwards, rats were treated with quercetin (50 mg/kg/d, orally for 7 consecutive days, Group 6: received quercetin; afterwards, rats were simultaneously treated with gentamicin plus quercetin with the same doses, and Group 7: received gentamicin, calcium acetate (lower dose), and quercetin simultaneously. Results: The study demonstrated the nephrotoxic impacts of gentamicin biochemically and histopathologically. Gentamicin treatment induced a significant increase in blood urea nitrogen (BUN) and serum creatinine levels besides a significant elevation in C-reactive protein (CRP) level. The significant increase in the tissue malondialdehyde(MDA) level and the significant reduction in the tissue superoxide dismutase(SOD) and glutathione(GSH) levels demonstrated that gentamicin-induced nephrotoxicity was mediated through oxidative stress reactions. Gentamicin-induced degenerative changes in renal tubules and glomeruli were also reported. Conclusion and clinical relevance: The use of both calcium acetate (lower and higher doses) or quercetin (therapeutically and prophylactically) in combination with gentamicin significantly minimized its nephrotoxicity as revealed from decreasing BUN, serum creatinine, CRP levels, oxidative stress reactions, and histopathological alterations with better protective effect of quercetin than Ca acetate. Co-administration of both calcium acetate and quercetin with gentamicin could prevent gentamicin-induced nephrotoxicity.

Takikardia supraventrikular (SVT) mewakili serangkaian takiaritmia yang berasal dari sirkuit atau fokus yang muncul di atas bundel His dan mengakibatkan denyut jantung melebihi 100 kali/menit. Takikardia reentri atrioventrikuler (AVRT) ortodromik merupakan jenis SVT kedua yang paling umum dijumpai pada sekitar 55% pasien dengan sindrom WolffParkinson-White (WPW). Sindrom WPW merupakan bentuk kelainan pre-eksitasi ventrikel yang paling umum dijumpai. Sindrom ini ditandai dengan adanya jalur aksesori antara atrium dan ventrikel yang memungkinkan adanya rute alternatif untuk depolarisasi ventrikel. Dilaporkan seorang wanita, 34 tahun dengan sindrom WPW yang terdiagnosis setelah terminasi dari takikardi kompleks sempit melalui manuver valsava yang dimodifikasi. Manuver ini merupakan teknik lini pertama yang biasa digunakan untuk mengembalikan irama sinus. Teknik non-invasif ini berfungsi untuk memperpanjang periode refrakter nodus AV melalui peningkatan tekanan intrathorakal dalam waktu singkat sehingga menstimulasi aktivitas baroreseptor di lengkung aorta dan karotis yang selanjutnya meningkatkan tonus parasimpatis. Sebagai kesimpulan, dokter perlu menyadari bahwa manuver ini berpotensi untuk menginduksi takiaritmia letal akibat blokade nodus AV sehingga memicu konduksi melalui jalur aksesori pada pasien dengan sindrom pre-eksitasi.

The attack strategy proposed in our work uses Duo-Attack using Jamming and Spoofing to evaluate the experiment and record the observations.
Optimal Multipath Conveyance with Improved Survivability for WSN’s In Challenging Location
Authors: Zong Chen Dr. Joy Iong
Published: May 2020

The sensor networks with the capability of conveying information’s through the wireless medium in many circumstances are affected by the inner energy and the exterior atmospheric changes as the sensors are employed in the areas that are beyond human reach and left uncared. Since routing procedure seems as the main source of energy utilization in these types of networks formulated by the sensors and as the prevailing routing procedures considers the parametric optimization from the network perception alone eluding the atmospheric influences over the network from the exterior sources, makes the sensors obtuse to the sudden unexpected changes in the atmosphere. So this leads to failure in conveyance of information’s due to the failure in the routing and the fading of the path established. To manage such circumstance effectively the paper formulates a multi path conveyance with improved survivability for wireless-sensor-networks. The method takes into consideration the residual energy, depth and the dynamic changes in the atmosphere. The developed routing evades the information from passing over the hazardous area and forms a reliable conveyance by creating an atmosphere based on the monitoring competencies of the sensor network. The formulate method is experimentally evaluated using the network simulator-2 to acquire the vital enhancements in the life expectancy of the network framed and the delivery rate of the packets.
Computer Vision on IOT Based Patient Preference Management System

Published: May 2020

Patient preference management is an essential work for any healthcare scheme to give priority to the needy patient. The work is generally carryout by a caretaker in the healthcare block to enroll their details of the patient on computer to find out and suggest an available consultant and time slot for the patient. These kind of usual works can be helpful up to certain normal conditions only. During uncertain times like viral explosion or war or nature disaster, the usual system will make the patient to wait in a queue for enrollment process. Most of the time it is intolerable to make a severe injured person to wait in the queue for the treatment. At the same time, during viral explosion the people were asked to stay at their home and for treatment they have to make a phone call to the care taking team for expressing their situation and health status. Attending a huge number of phone calls manually and providing a good suggestion to the caller is a challenging work for any healthcare team. The proposed IoT based computer vision system suggests the patient to send their status through a mobile phone message or email to the healthcare server to segregate the status of patient as emergency, severe and follow-up categories. This makes the healthcare team to identify the needy patient at right time to serve them. The proposed system is simulated with different computer vision algorithm and analyses its accuracy, time delay and drop rate to make a reliable patient preference management system.
Considerations on the optimal processing capacity of beet sugar factories
Authors: Schick Rudolf
Published: May 2020

The economic situation of the European sugar industry is currently very tense. The expected introduction of a climate-neutral mode of operation by 2050 will require considerable investment in the coming decades. This will further strengthen the cost advantages of the cane sugar industry, which, in contrast to the beet sugar industry, has for many years been obtaining most of its energy requirements from the renewable fuel bagasse. In order to remain competitive with the cane sugar industry, further reductions in production costs are necessary. As it is hardly possible to increase efficiency through technological improvements, the most promising measures to reduce production costs will be to further increase the processing capacity of the individual factories and possibly extend the campaign. Using a simplified mathematical model, the influence of transport costs, labour costs and constant costs on the optimal capacity of beet sugar factories is investigated. The lowest production costs for white sugar are used as an optimality criterion.

Published: May 2020

Alicerçada em três tendências em Educação Matemática surge a aliança entre História da Matemática (HM), Tecnologias Digitais em Informação e Comunicação (TDIC) e Investigação Matemática (IM). Considerando que cada uma das referidas tendências possui argumentos favoráveis ao uso em prol do ensino e aprendizagem de Matemática isoladamente, a aliança busca conexão desses de modo a compor mais uma proposta pedagógica no campo da Educação Matemática. Baseia-se assim, por exemplo, nos argumentos favoráveis ao uso da HM de Miguel e Miorim (2019), nas considerações da informática na Educação Matemática de Borba e Penteando (2019) e nas ponderações da IM de Ponte, Brocardo e Oliveira (2019), delineando ainda um constructo que perpassa por outras referências de aspectos teórico e metodológicos. Nessa ótica, nesse artigo almeja-se realizar uma apreciação do delineio da aliança e seus fundamentos juntamente com a apresentação de práticas que emergem da elaboração de produtos educacionais respaldados na mesma a partir de pesquisa da abordagem qualitativa. Desse modo, perpassa pelos moldes da aliança entre HM, TDIC e IM apontando como resultado parâmetros de sua elaboração, termos e expressões inerentes, nortes metodológicos para elaboração de proposta, entre outros aspectos.

Published: May 2020

The Best Value (BV) environment was introduced into the Netherlands in 2006. By 2008 testing was being done by a partnership of Arizona State University and Scenter (Sicco Santema, professor from Delft University). In 2010, the first significant test of the BV approach was done by the Rijkswaterstaat to deliver the $1B fast track infrastructure projects, and by 2015, the BV approach had become the “buzzword” of procurement and the professional procurement organization NEVI. However, in the delivery of professional engineering services, larger, more traditional services which were built on a system of relationships between clients and vendors, clients controlling the expert, and the importance of “billable man-hours”. The transition from a traditional approach to a BV approach is very challenging. Large traditional professional organizations naturally will have more difficulty adapting to the new approach. The BV approach utilized the expertise of experts to replace the need for relationships and owner management, direction and control (MDC). It also places less value on traditional practices that have been used by professional services to get business (relationships and working together with the client in a trust based relationship). The study captures the efforts of a very successful engineering firm (the second largest in the Netherlands) as they attempt to become successful in this new approach. The Best Value team that they have put together has had outstanding results in using the BV approach to changing their paradigm.

Published: May 2020

Summary. Posttraumatic (secondary) arthrosis of the shoulder joint, which develops as a result of fractures of the proximal epimetaphysis of the humerus, accounts for about 10% of all arthrosis cases of the shoulder joint, regardless of therapeutic tactics. Objective: to investigate the main causes of the development of post-traumatic arthrosis of the shoulder joint in patients with fractures of the proximal epimetaphysis of the humerus. Materials and Methods. The clinical group consisted of 295 patients with fractures of the proximal epitaphysis of the humerus, who from 2009 to 2020 were treated at the departments of the SI “Institute of Traumatology and Orthopedics of NAMS of Ukraine” (Kyiv). Of these, 55 (18.64%) were patients who had post-traumatic arthrosis of the shoulder joint. The age of the patients ranged from 27 to 68 years (mean age 42.7±9.5 years); men were 155 (52.5%), women 140 (47.5%). The presence of post-traumatic omarthrosis was determined in terms of 3 to 5 years after the fracture. All patients with post-traumatic osteoarthrosis of the shoulder joint, depending on the treatment, were divided into two groups: group A – patients after metal osteosynthesis of the proximal epimetaphysis of the humerus, group B – patients who underwent conservative treatment. Group A included 35 (63.6%) patients, group B – 20 (36.4%) patients. A general AS/ASIF classification was used to determine the type of a fracture. Conclusions. The highest number of cases of post-traumatic omarthrosis after conservative treatment was found in patients with type A1 fractures – 10.9% and A2 – 14.6%; after surgical treatment, post-traumatic omarthrosis was developed in patients with type C3 fractures – 12.6% and A3 – 14.6% (p≥0.05). The main reason for the development of post-traumatic omarthrosis is aseptic necrosis of the shoulder head – 61.8% (p≤0.05), which is more common in patients with type B and C fractures according to AO. The greatest impact on the development of omarthrosis in patients with fractures of the proximal epimetaphysis of the humerus is the load on the shoulder joint, both during rehabilitation and in daily life, and the presence of contracture in the shoulder joint.

Published: May 2020

Penelitian ini mendiskusikan tentang proses harmoni internal diantara ‘dimensi sertaan jiwa’, yaitu Al-ruh dan Al-hawa. Jiwa (Al-nafs) adalah diri yang memiliki peran utama dalam proses harmoni tersebut. Dengan pendekatan kepustakaan (library reseach), proses harmoni tersebut dijelaskan pada kerangka konsep Psikologi Islam. Untuk mendinamiskan jiwa, Allah SWT meyertakan hawa nafsu (al-hawa) pada diri manusia. Hawa nafsu pada awal dan dasarnya memilki kecenderungan negatif (al-nafs al-ammarah bi al-su), Energy hawa nafsu yang dapat dikendalikan akan bertransformasi menjadi dorongan positif (al-nafs al-muthmainah). Ketaatan jiwa terhadap anjuran kebaikan dari al-ruh adalah kunci utama pengendalian al-hawa. Al-ruh adalah diemensi sertaan pada jiwa yang memiliki peran startegis dalam membimbing jiwa supaya tetap dijalan kebaikan.
