Published: August 2021

Bu araştırma uzaktan eğitim sürecinde öğretmenlerin örgütsel değişime hazır olma ve örgütsel muhalefet algı düzeylerini belirlemek amacıyla gerçekleştirilmiştir. Öğretmenlerin görüşlerinin cinsiyet, medeni durum, öğrenim düzeyi ve mesleki kıdem değişkenleri açısından anlamlı farklılık gösterip göstermediğinin belirlenmesi araştırmanın alt problemleri olarak alınmış ve öğretmen görüşleri bu bağımsız değişkenlere göre değerlendirilmiştir. Bu kapsamda araştırma modeli olarak genel tarama modeli tercih edilmiştir. Araştırmanın evrenini Van ili Merkez İpekyolu ilçesinde görev yapan öğretmenler oluşturmaktadır. Araştırmanın örneklemi evrenden tabakalı örnekleme yolu ile farklı branşlardan seçilen toplam 231 öğretmen oluşturmaktadır. Veri toplamak için Çalışkan (2019) tarafından Türkçeye uyarlanan “Örgütsel Değişime Hazır Olma Ölçeği” ve Dağlı (2015) tarafından Türkçeye uyarlaması yapılan “Örgütsel Muhalefet” ölçeği kullanılmıştır. Ayrıca öğretmenlerin kişisel bilgileri hakkında dört maddelik (cinsiyet, medeni durum, öğrenim düzeyi ve mesleki kıdem) bir “Kişisel Bilgi Formu” kullanılmıştır. Toplanan veriler üzerinden betimsel istatistikler yapılmıştır. Yapılan araştırma neticesinde; öğretmenlerin örgütsel değişime hazır olma ve örgütsel muhalefet algı düzeylerinin orta düzey olduğu, öğretmenlerin örgütsel değişime hazır olma algılarının cinsiyetlerine ve mesleki kıdemlerine göre anlamlı şekilde farklılık gösterdiği, medeni durumları ve mezuniyet düzeylerine anlamlı şekilde farklılık göstermediği bulunmuştur. Ayrıca öğretmenlerin örgütsel değişime hazır olma ile örgütsel muhalefet algı düzeyleri arasında yüksek düzeyde anlamlı ve pozitif yönde bir ilişki; örgütsel değişime hazır olma ile dikey muhalefet algı düzeyi arasında orta düzeyde anlamlı ve pozitif yönde bir ilişki; örgütsel değişime hazır olma ile yatay muhalefet algı düzeyi arasında yüksek düzeyde anlamlı ve pozitif yönde bir ilişki olduğu bulgusuna ulaşılmıştır. Öğretmenlerin yaşadıkları değişimlerin ve örgütsel muhalefet davranışlarının sebeplerinin özellikle uzaktan eğitim sürecinde daha iyi anlaşılması açısından nitel çalışmalarla desteklenmesinin önemi vurgulanmıştır.

Published: August 2021

Bu çalışma Bilgisayar ve Öğretim Teknolojileri Öğretmenliği (BÖTE) bölümü Öğretim Tasarımı dersinin öğrenci merkezli yöntemler kullanılarak yeniden tasarlanması ve yapılan tasarımın detaylı olarak incelenmesini içermektedir. Bugün yüksek öğretimdeki birçok araştırma, öğretmen eğitiminde derslerin sadece kavramsal düzeyde işlendiğini ve gerçek hayat uygulamaları açısından zayıf olduğunu rapor etmektedir. Öğrenciyi merkeze alarak gerçek hayat uygulamaları ile anlamlı tecrübeler oluşturmak için, öğretim tasarımı dersinin öğreticisi ve aynı zamanda tasarımcısı “tasarım yoluyla anlama” ve “ters yüz edilmiş öğrenme” yaklaşımlarını dersin tasarımında kullanmıştır. Dersin tüm yönetimi ve materyallerinin paylaşımı Canvas öğrenme yönetim sistemi kullanılarak yapılmıştır. Araştırma deseni olarak durum çalışması kullanılmıştır. Çalışmada öğretim tasarımı dersinin yeniden tasarlanması ve uygulanması sürecindeki bütün deneyimlerini paylaşılmış ve bu süreç değerlendirerek öğrenci merkezli ders tasarımı için uygulamaya yönelik ve kuramsal önerilerde bulunulmuştur. Yapılan bu çalışmada, öğrenci merkezli tasarımların ciddi planlama ve zaman gerektirdiği tecrübe edilmiştir. Öğrencilerin, öğrenme yönetim sistemlerinde kısıtlı tecrübe sahibi olması, öğretim sürecinin başında bir engel oluşturması öngörülmüş ve muhtemel kısıtlamalar ve zaman kayıpları düşünülerek bir planlama yapılmıştır. Dersin bir öğrenme yönetim sistemi üzerinden yürütülmesi hem öğrenci hem de öğretim elemanı açısından dersin ilerleyen haftalarında uygulanmasını kolaylaştırmıştır. Ters yüz edilmiş öğrenme ve tasarım yoluyla anlama yaklaşımlarının uygulanmasında ortam şartlarının iyi analiz edilmesi gerektiği önemli bir değerlendirme sonucu olarak karşımıza çıkmaktadır. Öğretmen adayları uygulamaya dayalı ve gerçek hayat ile ilişkili bir tasarımı değerli bulduklarını fakat takım çalışmalarında kendi ekip üyelerini belirlemek istediklerini dile getirmişlerdir.

Türkiye’de bazı devlet okullarında üniforma, bazı devlet okullarında serbest kıyafet resmi olarak uygulanıyor görünse de gözlemler tutarlı bir uygulamanın olmadığı yönündedir. Bu tutarsız uygulamaların öğrencileri nasıl etkilediği hakkında çok az şey bilinmektedir. Bu araştırmada Malatya ilinde lise eğitimine devam eden ergenlerden elde edilen veri kullanılarak, ergenlerin okul kıyafetinin nasıl şekillendiği ve bu kıyafetlerin okulda hangi sorunlara neden olduğu değerlendirilmiştir. Bu amaçla yaşları 16 ila 18 arasında değişen 36 lise öğrencisi ile nitel görüşme yapılmıştır. Yapılan nitel görüşmelerin tematik analizi sonucunda şu üç ana tema belirlenmiştir: ‘kıyafeti tercihi, kıyafet tercihini etkileyen faktörler, kıyafet tercihinin okulda yansımaları’. Elde edilen bulgular çerçevesinde psikolojik yardım hizmeti sunan profesyonellere ve okul yöneticilerine uygulamaya yönelik öneriler sunulmuştur.

Authors: Bojórquez Ietza , Odgers-Ortiz Olga , Olivas-Hernández Olga L.
Published: September 2021

Introduction. Migrants could be at increased risk of the psychosocial and mental health consequences of the COVID-19 pandemic. Research is needed to assess their needs and the most useful interventions in this regard. Objective. To describe the mental health consequences of the pandemic and lockdown measures among migrants living in shelters in Tijuana, Mexico, during the COVID-19 pandemic, barriers to mental healthcare during this period, and the key elements of psychosocial support provided by civil society organizations (CSOs), as described by shelters’ staff. Method. In April-May 2020, we conducted a rapid qualitative study through interviews with persons providing services at eight migrant shelters, complementing the information with data from an ongoing ethnographic project. We situated the results within the levels of the United Nations’ Inter-Agency Standing Committee (IASC) pyramid of psychosocial and mental health support. Results. In addition to fear of contagion and economic insecurity, migrants experienced emotional distress associated with hardening migration policies, and the difficulties of having to find shelter in place in non-private spaces. Some CSOs continued or adapted previous psychosocial support activities, helping migrants navigate these issues, but other activities stopped amidst physical distancing measures and because of limited resources. Migrants themselves implemented some group activities. There was a surge of civil society initiatives of online support, but some shelters laeked the technological and other resources to benefit from them. Discussion and conclusion. Migrants require a tailor made response to their mental health needs in the COVID-19 pandemic, such as the one provided by CSOs.

Published: September 2021

Este artículo presenta un estudio de caso paradigmático del planeamiento urbanístico expansivo característico de la burbuja inmobiliaria que tuvo lugar en España entre los años 1997 y 2007. Se trata del municipio de Sariegos, en el entorno de León, como representativo de los procesos de descentralización residencial y suburbanización en el área urbana de una ciudad media española. El enfoque se centra en el análisis de los documentos de planeamiento, desde el punto de vista cuantitativo (dimensión de la clasificación de suelo) y cualitativo, a través del análisis del discurso que justifica la necesidad de crecimiento. Posteriormente, se analiza el grado de desarrollo y ejecución de las propuestas de planeamiento, ya en el contexto de la crisis inmobiliaria desatada a partir de 2007. Una vez constatada la sobredimensión del planeamiento y la existencia de importantes paquetes de suelo sin urbanizar o sin edificar, se concluye reflexionando sobre el presente y las propuestas que podrían hacerse de cara al futuro para la reconducción de los errores cometidos por el urbanismo expansionista.

Authors: Novikov Kirill A. , Tamrazova Olga B. , Matushevskaya Yuliya I.
Published: September 2021

Background. Taking into account the data of recent studies on the treatment of rosacea, the development of new methods of treating this dermatosis using complex physiotherapeutic approaches and their synergism is of scientific and practical interest. In this work, we took into account the synergism of physiotherapeutic effects exerted by intense pulsed light and submilisecond neodymium 1064 nm laser radiation, as well as an increase in the destruction of pathologically altered vessels observed with the sequential use of both procedures.
Aims: to assess the effect of complex phototherapy on changes in the indicators of the dermatological index of the symptom scale and the dermatological index of quality of life, reflecting the effect of the therapy on the clinical manifestations of the disease and the patient's subjective assessment of the skin condition.
Material and methods. In the period 20172020 we conducted a randomized controlled study in which 130 patients with a combination of rosacea subtypes took part. All patients were divided into 4 groups. In each separate group, the following types of therapy were used: in group I laser therapy and 1% metronidazole cream; in group II phototherapy and 1% metronidazole cream; in group III complex photo-laser therapy and 1% metronidazole cream; in the comparison group (IV), patients received only 1% metronidazole cream. The treatment included 6 sessions with an interval of 2 weeks, with a total duration of 3 months. The effectiveness of therapy was assessed according to the results of the dermatological index of quality of life (DQL) and the dermatological index of the symptom scale (DYS) before and after treatment.
Results. The developed complex method of combination of rosacea subtypes therapy demonstrated maximum efficiency, which was reflected in the maximum (by 55.21%) decrease in DYS in group III compared with the other three groups: in group I, the decrease in DYS was 30.54%, in II 21.51%, in IV 21.56%. The DQL in group III decreased by 67.4%, which was significantly higher than the indicators of the other three groups: in group I, DQL decreased by 31.3%, in group II by 27.4%, in IV by 20.7%.
Conclusion. After the course of complex phototherapy in the group of patients with combination of rosacea subtypes, there was a decrease in the severity of clinical manifestations of the disease, as well as an increase in the quality of life of patients according to the data of the DYS and DQL, respectively.

Published: September 2021

Background. The annual death rate from stroke in Russia remains the highest in the world. Aims: To study the influence of combined methods of medical rehabilitation on the psychological status and functional independence of patients with post-stroke spasticity. Materials and methods. The article presents data on the effectiveness of the influence on the psychological status and functional independence of the combined methods of medical rehabilitation in 60 patients with ischemic stroke with movement disorders in the form of hemiparesis with increased muscle tone by the type of spasticity in the long-term period. The patients were divided into 2 groups comparable in terms of clinical and functional characteristics: the main group (n=30), who received combined methods of physiotherapy (thermotherapy, oxygen therapy, oxyhyperthermia, vibrotherapy, aromatherapy) from the Alpha LED Oxu Light Spa apparatus in addition to the standard rehabilitation complex , which includes exercise therapy, medical massage, kinesitherapy, and a control group (n=30), who received only a standard rehabilitation complex. To assess the initial psychological status and functional independence of the observed patients undergoing medical rehabilitation in the period from 3 to 6 months after the disease, the SAN method (well-being, activity, mood) and the FIM scale were used. Results. Before the start of rehabilitation in all patients included in the study. Тhere was a moderate degree of deterioration in well-being, a decrease in activity and mood, as well as a decrease in indicators of independence in everyday life. After the course of treatment (on day 14) and in the long-term period (after 8 months) the patients of the main group had a pronounced positive dynamics of the psycho-emotional status, which was manifested in an improvement in the indicators of well-being by 1.93 times (by 28%), activity by 1.95 times (by 29.6%) and mood by 2.01 times (by 29.8%) points. In the control group, after the standard course of treatment, there was less pronounced dynamics of psychometric indicators. When evaluating the results of functional independence on the FIM scale, there was a significant improvement in the indicators of independence in everyday life by 32%. Conclusion. The use of combined methods of medical rehabilitation in patients with post-stroke spasticity contributes to a significant increase in their quality of life and psychological status, which is confirmed by the FIM and SAN tests.
New computer technologies to determine postmortem interval by the Henssge method
Authors: Nedugov German V.
Published: September 2021

Background: The Henssge method is still the main thermometric method to determine postmortem interval. However, its existing software implementations are characterized by several disadvantages associated with copying simplified nomographic variants of the original mathematical models without any optimization attempts, as well as procedural imperfection in finding the roots of implicit functions. In this paper, methods are proposed for optimizing solutions to the Henssge mathematical models and determine their errors, as well as software application implementation. Aim: Optimization of the Henssge algorithm and development of a series of applications based on the obtained data, designed to determine postmortem interval. Material and methods: Methods for solving double exponential Henssge models and determining their errors based on computational mathematics and regression modeling using the least-squares method with subsequent implementation in the format of computer programs in C# language optimized. Results: The discrete nature of residual variance changes of the double exponential Henssge models intended to determine the postmortem interval according to rectal and cranioencephalic thermometry data under constant external temperature conditions is eliminated. The interval estimate determination of postmortem interval at any confidence probability is possible. The application program Warm Bodies HR was developed, which implements applied optimization methods. The application program Warm Bodies AHBG, designed to determine postmortem interval by the Henssge method in a single discrete decrease or increase conditions in the constant temperature of the external environment, including a change in the cooling conditions of the corpse, was developed. The search for the roots of implicit functions in programs is carried out using the Newton tangent method, which ensures continuous source data nature and eliminates errors associated with the need to round directly measured physical quantities. Conclusions: The developed programs are recommended for forensic medical expert practice to determine postmortem interval.
Somnier. About one case of hereditary six-fingered. Bemerkungen zu einem Fall von vererbter Sechsfingerigkeit. Klinik, t. psych. u. nerv. Krankh. v. R. Sommer. B. V. H. 3. S. 297
Authors: Averbuch R.

The author describes a case of six-fingeredness in the family, in which this abnormality has already been observed in the course of four generations. On this occasion, he cites a whole series of works concerning the question of the inheritance of morphological abnormalities, both in humans and in animals. In one of these works (Gruber. Vortrag ber die Vererbung. Deutsche med. Wochenschz. 1909. S. 1995) it is indicated that, as a rule, the number of deformities decreases from generation to generation, if the deformities are not introduced from outside by marriages and are not amplified by kindred marriage (Insucht). Further in the same work, it is indicated that the appearance of such abnormal signs follows the apparently Mendel's laws of inheritance.

Liver transplantation for hepatocellular carcinoma with portal vein tumor thrombosis
Authors: Kim Sang Jin , Kim Jong Man
Published: September 2021

Traditionally, liver transplantation for hepatocellular carcinoma with portal vein tumor thrombosis is not recommended. However, with recent developments in locoregional therapies for hepatocellular carcinoma, more aggressive treatments have been attempted for advanced hepatocellular carcinoma. Recently, various studies on locoregional therapies for downstaging followed by living donor liver transplantation reported inspiring overall survival and recurrence-free survival of patients. These downstaging procedures included three-dimensional conformal radiation therapy, trans-arterial chemoembolization, stereotactic body radiation therapy, trans-arterial radioembolization, hepatic arterial infusion chemotherapy and combinations of these therapies. Selection of the optimal downstaging protocol should depend on tumor location, biology and background liver status. The risk factors affecting outcome include pre-downstaging alpha-fetoprotein values, delta alpha-fetoprotein values, disappearance of portal vein tumor thrombosis on imaging and meeting the Milan criteria or not after downstaging. For hepatocellular carcinoma with portal vein tumor thrombosis, downstaging procedure with liver transplantation in mind would be helpful. If the reaction of the downstaged tumor is good, liver transplantation may be performed.
Long-term survival after multimodal treatment involving radiotherapy for huge hepatocellular carcinoma with oligometastasis: a case report
Authors: Lee Byung Min , Seong Jinsil
Published: September 2021

The clinical efficacy of local ablative treatment for oligometastasis is widely accepted in most cancers. However, due to limited data, this has not been the case for hepatocellular carcinoma (HCC). Here, we report a case of pulmonary oligometastasis of a huge HCC that was treated by multimodality with liver-directed concurrent chemoradiotherapy (CCRT) plus subsequent resection of the primary lesion and local ablative radiotherapy (RT) for subsequent lung oligometastatic lesions. In this patient, liver-directed CCRT induced significant tumor shrinkage with compensatory hypertrophy of the non-tumor liver, followed by curative resection. Surgical resection of the first and second pulmonary metastatic lesions as well as local ablative RT of the third lesion achieved complete tumor regression, which led to long-term survival of 6 years. Therefore, the active use of local ablative RT requires full consideration in cases of oligometastatic HCC.

Open and Distance Education (ODE) has proven to be a viable alternative for teaching and learning with more inherent benefits compared to the traditional model of education. This mode of teaching and learning aimed at eradicating the challenges of the face-to-face mode of learning such as distance, age, work schedules, limited access and other factors that have made the face-to-face mode of learning rigid. ODE flexibility is evidenced in the ability of learners to learn ubiquitously at their own pace, anywhere, anytime using smartphones, laptops and desktop computers. As ODE grows and expands, the need to review its conceptual foundations, approaches and also to receive feedback from learners, employers and other stakeholders are becoming more imperative. This study employed an investigative approach via the use of online survey forms to elicit pertinent information regarding the learners’ perceptions and experiences at Ladoke Akintola University of Technology (LAUTECH) Open and Distance Learning Centre (LODLC). A total number of 2362 LODLC students participated in the online survey out of a total learners’ population of about 5,000. 54% of the respondents confirmed the adequacy of the LMS and the course material modules with more than 60% being able to easily access and download course materials from the LMS, 57% of the respondents rated the e-tutors to be effective knowledge facilitators while 60% believed the e-tutors stimulated learners’ interest by providing satisfactory answers to questions asked. This information amongst others will help administrators and management of LODLC programmes to make informed decisions about the conduct of the centres’ activities and adjust accordingly where necessary to improve service delivery.

In this work, N-(4-(N-acetylsulfamoyl)phenyl)-2-benzoyl-3-oxo-3-phenylpropanamide (HL) was synthesized by treating the appropriate dibenzoylaceticacid-N-carboxyethylamide with N-(4-aminophenyl)sulfonylacetamide and also characterized by using various analytical and spectroscopic techniques. Further, six metal complexes were synthesized from Zn(II), Ni(II), Mn(II), Cu(II), Co(II), and Pd(II) acetate and ligand in 1:2 ratio respectively. While Cu(II) and Pd(II) complexes exhibited square planar geometry, the others displayed octahedral geometry. Newly synthesized compounds were performed for antioxidant, DNA cleavage and antimicrobial activities. Tested compounds exhibited great potential antioxidant activity, especially Zn and Pd complexes. DNA cleavage results indicated that DNA could cleave with compounds through interaction. These compounds were investigated for their antimicrobial activity against seven microorganism species and showed moderate antimicrobial activity.
Consideraciones para el diseño de políticas fiscales para reducir la informalidad en América Latina y el Caribe
Authors: Cárdenas Mauricio , Fernández Cristina , Rasteletti Alejandro , Zamora Diego
Published: September 2021

La informalidad es un fenómeno multidimensional y persistente en América Latina y el Caribe, que tiene diversidad de causas y consecuencias. Esta publicación enfatiza el papel de la política fiscal como determinante clave de los elevados niveles de informalidad observados en la región, ya que define los incentivos que enfrentan los diferentes actores involucrados. La principal conclusión de este trabajo es que no existen soluciones fiscales simples y generalizables para reducir la informalidad, sino que se requieren estrategias integrales y a la medida, diseñadas en función de los niveles de productividad de las empresas, la calificación de los trabajadores, las condiciones fiscales y la normatividad preexistentes. El diseño de estas estrategias integrales y a la medida debe considerar la viabilidad política y fiscal de las medidas propuestas. Además, estas deben ser consensuadas entre las distintas partes interesadas, a fin de alentar su sostenibilidad en el tiempo, y tienen que presentar una secuencialidad adecuada. Si bien para muchos países de la región el fin último de estas estrategias debería ser la reducción de las cargas explícitas e implícitas sobre el trabajo formal, particularmente entre trabajadores de bajos ingresos, es importante lograr victorias tempranas que generen una dinámica a favor de la formalización. En este sentido, la introducción o reforma de regímenes simplificados de tributación y el fortalecimiento de las administraciones tributarias son un buen punto de partida pues, además de ser mecanismos generalmente efectivos para reducir la informalidad, tienen bajos costos políticos y fiscales. En muchos países estas medidas podrían introducirse de manera inmediata, para luego avanzar en el rediseño de políticas tributarias, sociales y laborales, que impulsen reducciones en la informalidad de mayor envergadura y sostenibles en el tiempo.

Published: September 2021

Regressions have been continuously received great attention. However, there are still open issues in regression, and two of the issues is regression with multicollinearity and outlier. Regularization (Ridge, Lasso, and Elastic Net) techniques implement a means to control regression coefficients. The methods can decrease the variance and reduce our sample error for tackle multicollinearity. In robust regression, it is a form of regression method designed to overcome outliers. Robust regression is an important method for analyzing data that are infected with outliers. The data have been interacted on the second order interaction. The data contained 435 different independent interaction variables. The primary focus of this paper is to analyze and compare the impact of three different variable selection techniques regularization regression algorithms for the data seaweed drying. After that, it will be analyzed through robust regression (Tukey Bi-Square, Hampel, and Huber). As the result, the Lasso-Hampel was better than others with the MAE (4.09641), RMSE (5.275992), MAPE (7.9962), SSE (182491.2), R-square (0.6514791), and R-square Adjusted (0.649279). The method of Lasso-Hampel is able to be relied on investigation of the accuracy in big data obtained from regularization and robust regression.

Co-infections or consecutive infections of mucormycosis and aspergillosis are very rare. Additionally, distinguishing between these two infections is also difficult as both these conditions have similar clinical features. We report two similar cases from Tamilnadu, who presented to a tertiary care centre in Puducherry, India in 2017 (first case) and 2019 (second case). The first case was a 70-year-old, non-diabetic male patient who presented with haemoptysis with a prior history of pulmonary tuberculosis. Computed tomography bronchial angiography revealed an air-crescent sign and the histopathological examination showed a fungal ball (aspergillus and mucor) in the right upper lobe and foci of fungal infection in the middle lobe. The second case was a 65-year-old diabetic male patient who presented with blackish expectoration and haemoptysis. A high-resolution computed tomography scan showed a reverse-halo sign in the right upper lobe. The results of the bronchoscopy-guided biopsy were consistent with a diagnosis of mixed mucormycosis and aspergillosis with angioinvasion. Both patients responded to amphotericin B with surgical excision of the affected lobe in the first case. A high degree of clinical suspicion, early surgical intervention and antifungal therapy are essential in the treatment of this rare co-infection.

An analysis a question of Mathematics Final Exam in Junior High School in the school year of 2005/2006-2018/2019 based on a taxonomy TIMSS obtain results that percentage spread of content and cognitive dimension still not appropriate yet with TIMSS Assessment Framework. At the content dimension, the spread of a question dominated by geometry domain while data and probability have spread of a question very few. Then, algebra and number domain pretty close proportion which have been specified by TIMSS. 2. the question of Mathematics Final Exam in Junior High School to the scope of material which set by the government was not given percentage distribution of materials obviously while cognitive level from government obtains a result that different with findings result in the researcher based on TIMSS taxonomy because there is different definition at government cognitive level from with TIMSS cognitive domain. There is a question that includes an application in government cognitive level however it includes knowing domain based on TIMSS taxonomy. Suitability a question of Final Exam from the school year of 2005/2006 till 2018/2019 indicate there are percentages increase from year to year close appropriate to proportion TIMSS Assessment Framework. It shows the percentage each other domain close proportion TIMSS in content and cognitive dimension.

Technological improvements in the era of the Industrial Revolution 4.0 can be applied to learning mathematics as a medium of improving teacher performance. In addition, a pandemic situation forces teachers and students to implement online learning. One of the learning media that can help teachers in learning mathematics online is Socratic. The Socratic system generally consists of four basic components: acting humanely, thinking humanely, thinking rationally and acting rationally. For example, the Socratic can provide alternative solutions to the differential equations problems. Mathematics problems can be recorded by the Socratic through three main features:1) home screen, which is used to take pictures of solving the problem needed; 2) search results, the image that has been recorded will be searched for a solution through Socratic's artificial intelligence in internet database, and 3) an explanation, the search results that have been obtained, have their own explanation. Teachers and students as users may find the best solution for each explanation by the Socratic. Meanwhile, this study uses four stages of the literature review process:1) search for relevant literature, 2) evaluation and source selection, 3) identification of themes, and 4) outline of the structure of the writing. This paper systematically investigates the use of the Socratic as a technology application that can assist mathematical problems.
