Spatial Information and the Legibility of Urban Form: Big Data in Urban Morphology
Authors: Boeing Geoff
Published: October 2019

Urban planning and morphology have relied on analytical cartography and visual communication tools for centuries to illustrate spatial patterns, propose designs, compare alternatives, and engage the public. Classic urban form visualizations – from Giambattista Nolli’s ichnographic maps of Rome to Allan Jacobs’s figure-ground diagrams of city streets – have compressed physical urban complexity into easily comprehensible information artifacts. Today we can enhance these traditional workflows through the Smart Cities paradigm of understanding cities via user-generated content and harvested data in an information management context. New spatial technology platforms and big data offer new lenses to understand, evaluate, monitor, and manage urban form and evolution. This paper builds on the theoretical framework of visual cultures in urban planning and morphology to introduce and situate computational data science processes for exploring urban fabric patterns and spatial order. It demonstrates these workflows with OSMnx and data from OpenStreetMap, a collaborative spatial information system and mapping platform, to examine street network patterns, orientations, and configurations in different study sites around the world, considering what these reveal about the urban fabric. The age of ubiquitous urban data and computational toolkits opens up a new era of worldwide urban form analysis from integrated quantitative and qualitative perspectives.

Published: October 2019

This study aims to analyze the implementation of the da’wah management conducted by IMSULTRA. This research is a descriptive qualitative type conducted in Southeast Sulawesi. The results of this study indicate that the management of the da’wah implemented by the DPW IMSULTRA has not been done comprehensively. This can be seen from the process of planning, recruiting, organizing, monitoring, and evaluating the muballigh which have not done in a comprehensive and systematic way. The alternative solution that can be done by DPW IMSULTRA to overcome the obstacles faced or at least minimize the negative implications caused is to recruit several personnel (staff) whose duty is to carry out various technical matters, form a more specific and comprehensive work program every year, compile analysis the needs of the muballigh, selective recruitment, compile job descriptions for each clear element to improve the lecture scheduling system, and implement a better muballigh monitoring and evaluation system.

Authors: Columbié Fariñas Teresa , Pérez Castillo Raydel , Cordero Gonzalez Yoanne
Published: October 2019

Introducción: La hemorragia del postparto inmediato es toda pérdida por sangrado uterino en las primeras 24 horas. La actuación médica incluye la identificación precoz de factores de riesgo, medidas para la estabilización hemodinámica, manejo quirurgico y anestesiológico. El objetivo está en evaluar la actuación médica protocolizada ante el manejo de los  factores asociados a la hemorragia obstétrica en el postparto inmediato.

Método: Se realizó un estudio descriptivo, longitudinal, prospectivo desde enero de 2015 a diciembre de 2018 en el Hospital Juan Bruno Zayas en una muestra de 105 puérperas. Se incluyeron las variables: factores de riesgos, etiología, acciones resolutivas, medidas de prevención, pautas diagnósticas preliminares, acciones terapéuticas, severidad del sangrado, respuesta al tratamiento y complicaciones. La evaluación de la actuación se estandarizó como: Muy Bien (96 a 100 %), Bien (90 a 95,9 %), Regular (85 a 89,9 %) y Mal (Menos de 85%).

Resultados: Factores de riesgo como el uso de oxitocina para la conducción del trabajo de parto (84,7%) y la sobre-distensión uterina (44,7%) generaron atonía uterina (35,2%)  y  lesiones del canal blando (35,2%) como etiologías más frecuentes. Se repusieron las pérdidas sanguíneas según lo establecido por el protocolo de actuación ante hemorragia del postparto inmediato.  En el 100% de las actuaciones se contuvieron como medidas de prevención la clasificación por Banco de Sangre y Alumbramiento Activo. Las pautas diagnósticas se encaminaron a la cuantificación de la hemorragia y la detección de los signos de agravamiento y choque hipovolémico. 

Conclusión: Se evaluó de muy bien la actuación médica protocolizada ante el  manejo de los factores asociados a la hemorragia obstétrica en el postparto inmediato. Se recomienda la búsqueda activa de los incipientes síntomas y signos de agravamiento desde un enfoque integral sindrómico y de riesgos que particularice el estado previo carencial y la repercusión hemodinámica individual.
The Mediating Effect of Trust on the Relationship between Psychological Contract and Psychological Employment Contract Breach. A Pilot Test.
Authors: Faruk Shakur
Published: October 2019

Employees always expect their employers to fulfil the promises according to the conditions embedded in the employment contract being the factor binding them together, because when the employer fail to meet up with the promises made, it results to psychological employment contract breach. Thus, it has become crucial for employers to uphold prior promises made to employees for the purpose of reciprocated gestures from the employees leading to increased motivation and performance in the organizations. This paper used little number of sample data in examining psychological contract, trust and psychological employment contract breach in Nigeria public universities. More so, it employ the use of SPSS (Version 24) to examine the reliability and cronbach alpha of the measurement instruments, as well as the content and face validity. Academicians and experts were used in the instrument assessment and the pilot study result revealed that the instruments are reliable with evidence of reasonable regularity.

Published: September 2019

Background: The present study aimed to introduce a rapid transmission dosimetry through an electronic portal-imaging device (EPID) to achieve two-dimensional (2D) dose distribution for homogenous environments.Material and Methods: In this Phantom study, first, the EPID calibration curve and correction coefficients for field size were obtained from EPID and ionization chamber. Second, the EPID off-axis pixel response was measured, and the grey-scale image of the EPID was converted into portal dose image using the calibration curve. Next, the scattering contribution was calculated to obtain the primary dose. Then, by means of a verified back-projection algorithm and the Scatter-to-Primary dose ratio, a 2D dose distribution at the mid-plane was obtained.Results: The results obtained from comparing the transmitted EPID dosimetry to the calculated dose, using commercial treatment planning system with gamma function while there is 3% dose difference and 3mm distance to agreement criteria, were in a good agreement. In addition, the pass rates of γ < 1 was 94.89% for the homogeneous volumes.Conclusion: Based on the results, the method proposed can be used in EPID dosimetry.
Masculinity and Neighborhood Bullying among Adolescents in Ibadan, Nigeria
Authors: Omobowale Mofeyisara Oluwatoyin , Akpabio Offiong Esop , Amodu Olukemi Kehinde
Published: October 2019

Masculinity, as an identity signifier along gender lines, varies from one society to another. The nature, definition, and expression of masculinity (dominance, oppression, violence, and aggression) through social interactions may breed bullying, as found in the Agbowo community of Ibadan, Nigeria. The data for the study were collected through mixed methods and revealed that patriarchal constructed masculinity allows for hegemonic dominance, aggression, oppression, and violent acts that foster bullying among adolescent males in Agbowo. Hence, to address bullying-related problems among adolescents, an understanding of the societal context in which it is carried out is required.
Clarifying Liquidity
Authors: Hugoson Rolf
Published: October 2019

This article is a history of liquidity presented as interaction between metaphors and theoretical concepts in social contexts. While taking note of Zygmunt Bauman’s metaphor “liquid modernity,” the study instead surveys the wider conceptual field. The text turns around mercantile liquidity (liquidity as clarification) and liquidity in modern economics (characteristic of all assets), as well as older metaphors, notably the famous phrase of the Communist Manifesto, “all that is solid melts into air” (Alles Ständische und Stehende verdampft), which is revealed to have resonance in texts by poets, notably Heinrich Heine. The main result is the historical consistency of the field, where liquidity is a promise of knowledge and clarity.

"Warn the Duke"
Authors: Miller-Melamed Paul
Published: October 2019

How has the Sarajevo assassination been conjured and construed, narrated
and represented, in a wide variety of media including fiction, film, newspapers, children’s literature, encyclopedias, textbooks, and academic writing itself? In what ways have these sources shaped our understanding of the so-called “first shots of the First World War”? By treating the assassination of Archduke Franz Ferdinand (28 June 1914) as a "site of memory" à la historian Pierre Nora, this article argues that both popular representations and historical narratives (including academic writing) of the political murder have contributed equally to the creation of what I identify here as the “Sarajevo myth.”
Operculoinsular cortectomy for refractory epilepsy. Part 1: Is it effective?
Authors: Bouthillier Alain , Weil Alexander G. , Martineau Laurence , Létourneau-Guillon Laurent , Nguyen Dang Khoa
Published: September 2019

OBJECTIVE

Patients with refractory epilepsy of operculoinsular origin are often denied potentially effective surgical treatment with operculoinsular cortectomy (also termed operculoinsulectomy) because of feared complications and the paucity of surgical series with a significant number of cases documenting seizure control outcome. The goal of this study was to document seizure control outcome after operculoinsular cortectomy in a group of patients investigated and treated by an epilepsy team with 20 years of experience with this specific technique.

METHODS

Clinical, imaging, surgical, and seizure control outcome data of all patients who underwent surgery for refractory epilepsy requiring an operculoinsular cortectomy were retrospectively reviewed. Tumors and progressive encephalitis cases were excluded. Descriptive and uni- and multivariate analyses were done to determine seizure control outcome and predictors.

RESULTS

Forty-three patients with 44 operculoinsular cortectomies were studied. Kaplan-Meier estimates of complete seizure freedom (first seizure recurrence excluding auras) for years 0.5, 1, 2, and 5 were 70.2%, 70.2%, 65.0%, and 65.0%, respectively. With patients with more than 1 year of follow-up, seizure control outcome Engel class I was achieved in 76.9% (mean follow-up duration 5.8 years; range 1.25–20 years). With multivariate analysis, unfavorable seizure outcome predictors were frontal lobe–like seizure semiology, shorter duration of epilepsy, and the use of intracranial electrodes for invasive monitoring. Suspected causes of recurrent seizures were sparing of the language cortex part of the focus, subtotal resection of cortical dysplasia/polymicrogyria, bilateral epilepsy, and residual epileptic cortex with normal preoperative MRI studies (insula, frontal lobe, posterior parieto-temporal, orbitofrontal).

CONCLUSIONS

The surgical treatment of operculoinsular refractory epilepsy is as effective as epilepsy surgeries in other brain areas. These patients should be referred to centers with appropriate experience. A frontal lobe–like seizure semiology should command more sampling with invasive monitoring. Recordings with intracranial electrodes are not always required if the noninvasive investigation is conclusive. The complete resection of the epileptic zone is crucial to achieve good seizure control outcome.

Published: September 2019

OBJECTIVE

The present study was designed to answer several concerns disclosed by systematic reviews indicating no evidence to support the use of computed tomography angiography (CTA) in the diagnosis of brain death (BD). Therefore, the aim of this study was to assess the effectiveness of CTA for the diagnosis of BD and to define the optimal tomographic criteria of intracranial circulatory arrest.

METHODS

A unicenter, prospective, observational case-control study was undertaken. Comatose patients (Glasgow Coma Scale score ≤ 5), even those presenting with the first signs of BD, were included. CTA scanning of arterial and venous vasculature and transcranial Doppler (TCD) were performed. A neurological determination of BD and consequently determination of case (BD group) or control (no-BD group) was conducted. All personnel involved with assessing patients were blinded to further tests results. Accuracy of BD diagnosis determined by using CTA was calculated based on the criteria of bilateral absence of visualization of the internal cerebral veins and the distal middle cerebral arteries, the 4-point score (4PS), and an exclusive criterion of absence of deep brain venous drainage as indicated by the absence of deep venous opacification on CTA, the venous score (VS), which considers only the internal cerebral veins bilaterally.

RESULTS

A total of 106 patients were enrolled in this study; 52 patients did not have BD, and none of these patients had circulatory arrest observed by CTA or TCD (100% specificity). Of the 54 patients with a clinical diagnosis of BD, 33 met the 4PS (61.1% sensitivity), whereas 47 met the VS (87% sensitivity). The accuracy of CTA was time related, with greater accuracy when scanning was performed less than 12 hours prior to the neurological assessment, reaching 95.5% sensitivity with the VS.

CONCLUSIONS

CTA can reliably support a diagnosis of BD. The criterion of the absence of deep venous opacification, which can be assessed by use of the VS criteria investigated in this study, can confirm the occurrence of cerebral circulatory arrest.

Operculoinsular cortectomy for refractory epilepsy. Part 2: Is it safe?
Authors: Bouthillier Alain , Weil Alexander G. , Martineau Laurence , Létourneau-Guillon Laurent , Nguyen Dang Khoa
Published: September 2019

OBJECTIVE

Operculoinsular cortectomy (also termed operculoinsulectomy) is increasingly recognized as a therapeutic option for perisylvian refractory epilepsy. However, most neurosurgeons are reluctant to perform the technique because of previously experienced or feared neurological complications. The goal of this study was to quantify the incidence of basic neurological complications (loss of primary nonneuropsychological functions) associated with operculoinsular cortectomies for refractory epilepsy, and to identify factors predicting these complications.

METHODS

Clinical, imaging, and surgical data of all patients investigated and surgically treated by our team for refractory epilepsy requiring an operculoinsular cortectomy were retrospectively reviewed. Patients with tumors and encephalitis were excluded. Logistic regression analysis was used for uni- and multivariate statistical analyses.

RESULTS

Forty-four operculoinsular cortectomies were performed in 43 patients. Although postoperative neurological deficits were frequent (54.5% of procedures), only 3 procedures were associated with a permanent significant neurological deficit. Out of the 3 permanent deficits, only 1 (2.3%; a sensorimotor hemisyndrome) was related to the technique of operculoinsular cortectomy (injury to a middle cerebral artery branch), while the other 2 (arm hypoesthesia and hemianopia) were attributed to cortical resection beyond the operculoinsular area. With multivariate analysis, a postoperative neurological deficit was associated with preoperative insular hypometabolism on PET scan. Postoperative motor deficit (29.6% of procedures) was correlated with fewer years of neurosurgical experience and frontal operculectomies, but not with corona radiata ischemic lesions. Ischemic lesions in the posterior two-thirds of the corona radiata (40.9% of procedures) were associated with parietal operculectomies, but not with posterior insulectomies.

CONCLUSIONS

Operculoinsular cortectomy for refractory epilepsy is a relatively safe therapeutic option but temporary neurological deficits after surgery are frequent. This study highlights the role of frontal/parietal opercula resections in postoperative complications. Corona radiata ischemic lesions are not clearly related to motor deficits. There were no obvious permanent neurological consequences of losing a part of an epileptic insula, including on the dominant side for language. A low complication rate can be achieved if the following conditions are met: 1) microsurgical technique is applied to spare cortical branches of the middle cerebral artery; 2) the resection of an opercula is done only if the opercula is part of the epileptic focus; and 3) the neurosurgeon involved has proper training and experience.

Published: September 2019

OBJECTIVE

Tractography-based targeting of the thalamic ventral intermediate nucleus (T-VIM) is a novel method conferring patient-specific selection of VIM coordinates for tremor surgery; however, its accuracy and clinical utility in magnetic resonance imaging–guided focused ultrasound (MRgFUS) thalamotomy compared to conventional indirect targeting has not been specifically addressed. This retrospective study sought to compare the treatment locations and potential adverse effect profiles of T-VIM with indirect targeting in a large cohort of MRgFUS thalamotomy patients.

METHODS

T-VIM was performed using diffusion tractography outlining the pyramidal and medial lemniscus tracts in 43 MRgFUS thalamotomy patients. T-VIM coordinates were compared with the indirect treatment coordinates used in the procedure. Thalamotomy lesions were delineated on postoperative T1-weighted images and displaced (“translated”) by the anteroposterior and mediolateral difference between T-VIM and treatment coordinates. Both translated and actual lesions were normalized to standard space and subsequently overlaid with areas previously reported to be associated with an increased risk of motor and sensory adverse effects when lesioned during MRgFUS thalamotomy.

RESULTS

T-VIM coordinates were 2.18 mm anterior and 1.82 mm medial to the “final” indirect treatment coordinates. Translated lesions lay more squarely within the boundaries of the VIM compared to nontranslated lesions and showed significantly less overlap with areas associated with sensory adverse effects. Translated lesions overlapped less with areas associated with motor adverse effects; however, this difference was not significant.

CONCLUSIONS

T-VIM leads to the selection of more anterior and medial coordinates than the conventional indirect methods. Lesions moved toward these anteromedial coordinates avoid areas associated with an increased risk of motor and sensory adverse effects, suggesting that T-VIM may improve clinical outcomes.
Intraoperative electrostimulation for awake brain mapping: how many positive interference responses are required for reliability?
Authors: Roux Franck-Emmanuel , Djidjeli Imène , Quéhan Romain , Réhault Emilie , Giussani Carlo , Durand Jean-Baptiste
Published: September 2019

OBJECTIVE

The purpose of this study was to characterize the reproducibility of language trials within and between brain mapping sessions.

METHODS

Brain mapping and baseline testing data from 200 adult patients who underwent resection of left-hemisphere tumors were evaluated. Data from 11 additional patients who underwent a second resection for recurrence were analyzed separately to investigate reproducibility over time. In all cases, a specific protocol of electrostimulation brain mapping with a controlled naming task was used to detect language areas, and the results were statistically compared with preoperative and intraoperative baseline naming error rates. All patients had normal preoperative error rates, controlled for educational level and age (mean 8.92%, range 0%–16.25%). Intraoperative baseline error rates within the normal range were highly correlated with preoperative ones (r = 0.74, p < 10−10), although intraoperative rates were usually higher (mean 13.30%, range 0%–26.67%). Initially, 3 electrostimulation trials were performed in each cortical area. If 2 of 3 trials showed language interference, 1 or 2 additional trials were performed (depending on results).

RESULTS

In the main group of 200 patients, there were 82 single interferences (i.e., positive results in 1 of 3 trials), 227 double interferences (2/3), and 312 full interferences (3/3). Binomial statistics revealed that full interferences were statistically significant (vs intraoperative baseline) in 92.7% of patients, while double interferences were significant only in 38.5% of patients, those with the lowest error rates. On further testing, one-third of the 2/3 trials became 2/4 trials, which was significant in only one-quarter of patients. Double interference could be considered significant for most patients (> 90%) when confirmed by 2 subsequent positive trials (4/5). In the 11 patients who were operated on twice, only 26% of areas that tested positive in the initial operation tested positive in the second and showed the same type of interference and the same current threshold (i.e., met all 3 criteria).

CONCLUSIONS

Electrostimulation trials in awake brain mapping produced graded patterns of positive reproducibility levels, and their significance varied with the baseline error rates. The results suggest that caution is warranted when 2 of 3 trials are positive, although the need for additional trials depends on the individual patients’ baseline error rates. Reproducibility issues should be considered in the interpretation of data from awake brain mapping.
Spinal dural arteriovenous fistula formation after scoliosis surgery: case report
Authors: Elswick Clay M. , Khalsa Siri Sahib S. , Saadeh Yamaan S. , Pandey Aditya S. , Oppenlander Mark E.
Published: September 2019

Spinal dural arteriovenous fistulas are diagnostically challenging lesions, and they are not well described in patients with a history of a spinal deformity correction. The authors present the challenging case of a 74-year-old woman who had previously undergone correction of a spinal deformity with subsequent revision. Several years after the last deformity operation, she developed a progressive myelopathy with urinary incontinence over a 6-month period. After evaluation at the authors’ institution, an angiogram was obtained, demonstrating a fistula at the T12–L1 region. Surgical ligation of the fistula was performed with subsequent improvement of the neurological symptoms. This case is thought to represent the first fistula documented in an area of the spine that had previously been operated on, and to the authors’ knowledge, it is the first case report to be associated with spinal deformity surgery. A brief historical overview and review of the pathophysiology of spinal dural arteriovenous fistulas is also included.
Readmission after endoscopic transsphenoidal pituitary surgery: analysis of 584 consecutive cases
Authors: Younus Iyan , Gerges Mina M. , Dobri Georgiana A. , Ramakrishna Rohan , Schwartz Theodore H.
Published: September 2019

OBJECTIVE

Hospital readmission is a key component in value-based healthcare models but there are limited data about the 30-day readmission rate after endonasal endoscopic transsphenoidal surgery (EETS) for pituitary adenoma. The objective of this study was to determine the incidence and identify factors associated with 30-day readmission after EETS for pituitary adenoma.

METHODS

The authors analyzed a prospectively acquired database of patients who underwent EETS for pituitary adenoma from 2005 to 2018 at NewYork-Presbyterian Hospital, Weill Cornell Medicine. Clinical, socioeconomic, and radiographic data were reviewed for cases of unplanned readmission within 30 days of surgery and, as a control group, for all other patients in the series who were not readmitted. Statistical significance was determined with an alpha < 0.05 using Pearson’s chi-square and Fisher’s exact tests for categorical variables and the independent-samples t-test for continuous variables.

RESULTS

Of 584 patients undergoing EETS for pituitary adenoma, 27 (4.6%) had unplanned readmission within 30 days. Most readmissions occurred within the first week after surgery, with a mean time to readmission of 6.6 ± 3.9 days. The majority of readmissions (59%) were for hyponatremia. These patients had a mean sodium level of 120.6 ± 4.6 mEq/L at presentation. Other causes of readmission were epistaxis (11%), spinal headache (11%), sellar hematoma (7.4%), CSF leak (3.7%), nonspecific headache (3.7%), and pulmonary embolism (3.7%). The postoperative length of stay was significantly shorter for patients who were readmitted than for the controls (2.7 ± 1.0 days vs 3.9 ± 3.2 days; p < 0.05). Patients readmitted for hyponatremia had an initial length of stay of 2.6 ± 0.9 days, the shortest of any cause for readmission. The mean BMI was significantly lower for readmitted patients than for the controls (26.4 ± 3.9 kg/m2 vs 29.3 ± 6.1 kg/m2; p < 0.05).

CONCLUSIONS

Readmission after EETS for pituitary adenoma is a relatively rare phenomenon, with delayed hyponatremia being the primary cause. The study results demonstrate that shorter postoperative length of stay and lower BMI were associated with 30-day readmission.

Published: September 2019

OBJECTIVE

There have been numerous studies demonstrating increased pain and disability when patients’ spinopelvic parameters fall outside of certain accepted ranges. However, these values were established based on patients suffering from spinal deformities. It remains unknown how these parameters change over a lifetime in asymptomatic individuals. The goal of this study was to define a range of spinopelvic parameters from asymptomatic individuals.

METHODS

Sagittal scoliosis radiographs of 210 asymptomatic patients were evaluated. All measurements were reviewed by 2 trained observers, supervised by a trained clinician. The following parameters and relationships were measured or calculated: cervical lordosis (CL), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sagittal vertical axis (SVA), cervical SVA (cSVA), and T1 slope, TK/LL, truncal inclination, pelvic tilt (PT), LL−PI, LL/PI, and T1 slope/PI. Patients were stratified by decade of life, and regression analysis was performed to delineate the relationship between each consecutive age group and the aforementioned parameters.

RESULTS

Cervical lordosis (R2 = 0.61), thoracic kyphosis (R2 = 0.84), SVA (R2 = 0.88), cSVA (R2 = 0.51), and T1 slope (R2 = 0.77) all increase with age. Truncal inclination (R2 = 0.36) and T1 slope/CL remain stable over all decades (R2 = 0.01). LL starts greater than PI, but in the 6th decade of life, LL becomes equal to PI and in the 7th decade becomes smaller than PI (R2 = 0.96). The ratio of TK/LL is stable until the 7th decade of life (R2 = 0.81), whereas PT is stable until the 6th decade (R2 = 0.92).

CONCLUSIONS

This study further refines the generally accepted LL = PI + 10° by showing that patients under the age of 50 years should have more LL compared to PI, whereas after the 5th decade the relationship is reversed. SVA was not as sensitive across age groups, exhibiting a marked increase only in the 7th decade of life. Given the reliable increase of CL with age, and the stability of T1 slope/CL, this represents another important relationship that should be maintained when performing cervical deformity/fusion surgery. This study has important implications for evaluating adult patients with spinal deformities and for establishing corrective surgical goals.

Diagnosis of causes of blindness in veterinary ophthalmology is an urgent issue. There are a large number of diseases of central and peripheral nervous system, which can lead to partial or complete loss of visual function in animals. Visual evoked potentials (VEP) of brain can be a reliable diagnostic research method to clarify the location of the disfunction and causes of blindness in dogs and cats. Together, the visual evoked potentials and electroretinography complement each other and give a greater idea of electrophysiology of visual process. In this article on the basis of large quantity of information we examine the ways of applying this method and the problems, connected with its use. It is important to understand that the VEP can reveal the functional disturbances of visual way, but does not give the information about the structural changes.
MicroRNAs are a key factor in the globalization of tumor-host relationships
Authors: Chekhun V.F.
Published: October 2019

Summary. A new round of molecular oncology development in the post-genomic era significantly changes the conventional understanding of the nature and origin of the malignant process. Increasingly, fundamental phenomena are emerging that change the “canonical” views of the dominant role of gene mutations that contribute to the uncontrolled proliferation and emergence of heterogeneous malignant cells. Recent numerous studies have shown that significant variability in the initiation, proliferation and control of the apoptotic program of tumor cells is due to numerous epigenetic processes, including the level of expression of microRNAs (miRNAs). This paper reviews the literature data and presents the results of own research in which miRNAs have been found to form a molecular phenotype for malignancy. Their role as a “conductor” of the functioning of a genetic-epigenetic orchestra that coordinates various aspects of malignancy has been suggested. MiRNAs have been shown to be an active participant in balancing mechanisms in the development of controversial processes in breast cancer cell lines of varying degrees of malignancy. The analysis of the literature data and the own studies of the expression profile of only a few miRNAs suggests that scientists and clinicians have received a new marker and a target that simultaneously plays the role of an active insider in both the oncogene-oncosuppressor relationship and in the globalization of this process at the tumor-host level. Further investigation of the “alarm” marker in this network will allow to reconsider the molecular genetic classification of neoplastic disease, which will provide the development of a new strategy for cancer therapy.

Penglihatan warna merupakan salah satu fungsi penglihatan yang penting dalam kehidupan sehari-hari. Akan tetapi, tidak semua orang dikaruniai kemampuan penglihatan warna yang normal. Salah satunya adalah penderita defisiensi penglihatan warna atau lebih dikenal dengan istilah buta warna. Buta warna adalah suatu keadaan dimana seseorang tidak dapat membedakan warna tertentu yang bisa dibedakan oleh orang lain dengan mata normal. Tingkat mobilitas dan kesibukan saat ini membuat rendahnya kesadaran dan kurangnya pengetahuan masyarakat mengenai kelainan buta warna, serta melakukan tes buta warna sejak dini. Gangguan buta warna dapat diketahui dengan melakukan test buta warna menggunakan buku tes metode Ishihara. Penilitan ini bertujuan untuk membuat aplikasi tes buta warna yang mengimplementasikan Metode Ishihara dengan teknik penalaran maju (forward chaining). Jenis buta warna yang dapat di identifikasi pada aplikasi ini yaitu: penglihatan normal, buta warna parsial, dan buta warna total. Aplikasi ini dirancang berbasis android menggunakan bahasa pemrograman Java dan XML serta menggunakan metode Artificial Intellegence dilanjutkan dengan pengujian sistem dengan menggunakan metode black-box dan white-box. Dengan adanya aplikasi ini dapat disimpulkan bahwa aplikasi tes buta warna berbasis android dengan menggunakan metode Ishihara dapat mempermudah masyarakat untuk melakukan tes buta warna guna mengetahui gangguan penglihatan warna terhadap mata dengan hasil diagnosa yang dapat diperoleh secara langsung melalui smartphone android.

Türkiye, İkinci Dünya Savaşı’ndan sonra Batılı Devletler ile ittifak kurmak istedi. Bu nedenle Ortadoğu’da ayrı bir savunma sisteminin oluşturulması için çalıştı. Mısır ise bölgenin lideri olmak istiyordu. Bu nedenle Mısır, İngiltere’yi Süveyş bölgesinden çekmek istedi. Fakat Türk yetkililer Mısır’ın bu isteğini onaylamadı. Kısa bir süre sonra Mısır ile Türkiye arasında büyükelçi krizi ortaya çıktı. Hulusi Fuat Tugay 1951 yılında Kahire’ye büyükelçi olarak gönderilmişti. Hulusi Fuat Tugay’ın eşinin Mısır Hanedanlığı ile akrabalık ilişkileri vardı. Büyükelçinin eşinin mallarına Mısır Hükümeti tarafından el konuldu. Hulusi Fuat Tugay buna tepki gösterdi. Kısa bir süre sonra Mısır yöneticileri tarafından sınır dışı edildi. Büyükelçi krizi ile ilgili haberler yerli ve yabancı basında yer aldı. Mısır basınına göre olay büyükelçiye yönelikti. Türk basını ise olayı, diplomatik yetersizlik olarak değerlendirdi. Çalışmamızda yerli ve yabancı basında yer alan haberler, büyükelçi krizinin nedenleri ve sonuçları incelendi.
