Parry-Romberg syndrome: is it a “relapsing-remitting” disease?
Authors: Kaya Tutar Nurhan , Akkas Sinem Yazıcı , Omerhoca Sami , Kale Nilufer , Saip Sabahattin
Published: December 2021

Parry-Romberg syndrome, also known as progressive hemifacial atrophy, is a rare, slowly progressive disorder characterized by unilateral, painless atrophy of the skin and subcutaneous tissue of the face. Neurological manifestations such as epilepsy, migraine and trigeminal neuralgia are relatively common and accompany in 15-20% of cases. Various etiologies such as infection, trauma, embryonic developmental dysfunction, sympathetic dysfunction and autoimmune disorders have been suggested as possible causes. Here we describe a 37-year-old woman whose disease manifested with dynamic contrast enhanced white matter changes over a period of two years, suggesting a “relapsing-remitting” course. Besides the inflammatory activity, positive serum-autoantibodies, inflammatory findings in cerebrospinal fluid, and an overlapping systemic autoimmune disorder may further support the hypothesis of autoimmune-inflammatory mediated pathogenesis.

Sandhoff disease is a rare type of hereditary (autosomal recessive) GM2-gangliosidosis, which is caused by mutation of the HEXB gene. Disruption of the β subunit of the hexosaminidase (Hex) enzyme affects the function of both the Hex-A and Hex-B isoforms. The severity and the age of onset of the disease (infantile or classic; juvenile; adult) depends on the residual activity of the enzyme. The late-onset form is characterized by diverse symptomatology, comprising motor neuron disease, ataxia, tremor, dystonia, psychiatric symptoms and neuropathy. A 36-year-old female patient has been presenting progressive, symmetrical lower limb weakness for 9 years. Detailed neurological examination revealed mild symmetrical weakness in the hip flexors without the involvement of other muscle groups. The patellar reflex was decreased on both sides. Laboratory tests showed no relevant alteration and routine electroencephalography and brain MRI were normal. Nerve conduction studies and electromyography revealed alterations corresponding to sensory neuropathy. Muscle biopsy demonstrated signs of mild neurogenic lesion. Her younger brother (32-year-old) was observed with similar symptoms. Detailed genetic study detected a known pathogenic missense mutation and a 15,088 base pair long known pathogenic deletion in the HEXB gene (NM_000521.4:c.1417G>A; NM_000521:c.-376-5836_669+1473del; double heterozygous state). Segregation analysis and hexosaminidase enzyme assay of the family further confirmed the diagnosis of late-onset Sandhoff disease. The purpose of this case report is to draw attention to the significance of late-onset Sandhoff disease amongst disorders presenting with proximal predominant symmetric lower limb muscle weakness in adulthood.

Authors:   School of Engineering and Technology, Central Queensland University, Australia, Sabrina Fariza , Azad Salahuddin , Sohail Shaleeza , Thakur Sweta
Published: December 2021

During the recent COVID-19 outbreak, educational institutions have transitioned to online teaching for all students for most of the programs. Due to lack of in-person interactions and monitoring, assessments in online courses may be more susceptible to contract cheating, collusion, fabrication and other types of academic misconduct than the assessments in face-to-face courses. This situation has raised several research questions that need immediate attention, such as what are the best possible options for online assessments and how to administer online assessments so that academic integrity could be preserved. The authors have conducted a scoping study and carried out an extensive literature review on i) different types of assessments that are suitable for online courses, ii) strategies for ensuring academic integrity, and iii) methods, tools and technologies available for preventing academic misconduct in online assessments. It is evident from the literature review that there are a range of options available for designing assessment tasks to detect and prevent violations of academic integrity. However, no single method or design is enough to eliminate all sorts of academic integrity violations. After thorough research and analysis of existing literature, the authors have provided a comprehensive set of recommendations that could be adopted for ensuring academic integrity in online assessments.

Authors: DAĞLIOĞLU Yeşim , ÖZTÜRK Betül
Published: December 2021

The green synthesis approach has benefits over traditional methods in silver nanoparticle synthesis that involve chemical agents interrelated environmental toxicity. For this reason, this approach has been preferred for the biosynthesis of silver nanoparticles (AgNPs). In addition, nanoparticles produced through plants are much more stable, large in size and shape range and can be biosynthesized in high amounts. Silver nanoparticles were synthesized from silver compound (AgNO3) using bioactive compounds of Mandragora autumnalis as capping and reducing agents. Synthesis nanoparticles (Ma-AgNPs) were characterized by SEM, TEM, X-ray diffraction and UV-vis absorption spectroscopy analyzes. X-ray diffraction analysis indicated that the nanoparticles had a crystalline structure. X-ray diffraction analysis demonstrated that the nanoparticles had a crystalline structure. In SEM and TEM images, the spherical shaped and average size of Ma-AgNPs is 20-30 nm. It has been noted that Ma-AgNPs show high antioxidant activity by using DPPH with Ascorbic acid as a standard. It showed a zone of inhibition against Gram positive (Bacillus subtilis, Staphylococcus aureus) and Gram negative (Escherichia coli and Pseudomonas aeruginosa) bacteria.

Retrospective Analysis of the Emergency Risk Management Theory
Authors: Dokukin P.A. , Kharchenko S.G.
Published: December 2021

A retrospective analysis of the emergency risk management theory is presented. A brief history of the origin of the main emergency risk management theory terms and concepts is presented in the article. The events that required theoretical comprehension of emergency situations, their legislative regulation and the need to search for new solutions are investigated. Special attention is paid to the evolution of the Seveso Directive of the European Union. The author analyzes the advantages and disadvantages of the "absolute security" concept, justifies the inevitability of the transition to the "acceptable risk" concept. The quantitative measure of taking 10-6 per year as the maximum acceptable (or maximum permissible) individual risk and 10-8 per year as a negligible risk is justified.

Authors: Yi Wook , Kim Bo Hyun , Kim Jeong Mi , Kim Yong Ki
Published: December 2021

Metastasis to the thyroid gland is rare, and the incidence of thyroid metastasis is from 1.4% to 3% for all thyroid malignancies. The most common metastatic malignancy to the thyroid gland is renal cell carcinoma. Ultrasonography is useful to assess the malignancy risk of thyroid nodules, and the ultrasonographic features of metastatic renal cell carcinoma in the thyroid gland are hypoechoic solid nodules with increased vascularity. Here, we report a case of metastatic clear cell renal carcinoma with benign ultrasonographic features and fine-needle aspiration cytology in the thyroid gland. A 76-year-old woman visited our hospital for surgical management of a growing left thyroid mass. Her history comprised previous left nephrectomy for an unknown reason. Thyroid ultrasonography revealed a well-defined, isoechoic, solid mass. Left thyroidectomy was performed, and the final diagnosis was metastatic clear cell renal carcinoma of the thyroid gland.

Published: December 2021

Purpose. Research of problems arising in law enforcement practice for the protection of the rights of consumers of educational services. Differentiation of judicial and other ways of protecting educational rights. The correlation of the standards for educational and consumer legislation in resolving disputes on protection of rights of consumers of educational services. Methodology: dialectics, analysis, synthesis, induction and deduction, formal legal method. Conclusions. The legislation on consumer protection applies exclusively to educational services provided on the basis of full reimbursement of training costs, i.e. under the appropriate commutative contracts for the provision of educational services. In order to apply measures to protect the rights of a consumer acting in good faith, it is necessary in each case to establish the scope of service provision in comparison with the degree course scheme. Consumer demands for a significant reduction in the cost of paid educational services in the absence of real grounds are a manifestation of «consumer extremism». Scientific and practical significance. The results obtained in this article can be used in further research to solve the problem, in scientific and pedagogical activities, and in law enforcement activities of bodies dealing with specific disputes. These provisions can also be useful to consumers, since the correct choice of the procedure and method of protection accelerates the achievement of the goal of protecting the violated right.

Purpose. To compare and analyze the trend of appearance of the pseudo-term “digital criminology” in the science of criminology and prove that this is incorrect. Methodology: induction, deduction, synthesis, analysis, formal legal method, comparative legal method, logical method. Conclusions. The evolution of methods of committing crimes and instruments of crime does not always require the evolution of the science of criminology and the emergence of its varieties. You just have to assess the prospects of extrapolative ways and methods of proving the circumstances of the crimes in the era of digitalization of social relations, in terms of the provisions of modern criminal law and only criminal-legal research unit. The definition of “digital criminalistics”, which has recently appeared in science, actually misleads the scientific community with its novelty and originality, since such criminalistics in nature does not exist a priori. It is necessary to speak only about forensic or expert research of carriers of digital (electronic or computer) information. In criminalistics, it is logical to develop a new direction-the forensic study of electronic media of digital information and the use of computer expertise in establishing all the circumstances of the crime committed. And this is just a new section of forensic technology, studying a new subject of research for this naki. Here, the traditional forensic methodology should be applied, which will be aimed “atlinking” the electronic carrier of digital information and the digital information itself to a specific crime and to a specific person. Scientific and practical significance. The research is aimed at orienting forensic theory and practice towards the study of specific objects and contributes to the fact that all these studies are further applicable to the practice of crime investigation, and not only for theoretical purposes.

Reinterpretasi Persepsi Keagamaan tentang Kekerasan terhadap Perempuan (Perspektif Maqashid al-Syariah)
Authors: Hakim Budi Rahmat , Herlinawati Herlinawati
Published: December 2021

Abstract: Conceptually, the existence of religion is actually an alternative for the creation of a reality without violence, especially against women. Islam introduces the concept of preventing violence against women which refers to substantive verses (ushuliyah), as well as a general purpose / basis of sharia (maqashid al-syariah). In the context of married life, there are some basic rules put forward by the Al Quran as a guarantee for the benefit of a wife to avoid physical and psychological violence in relation to fulfilling her rights as a woman. This paper seeks to analyze and find the idea of benefit outlined by sharia in its relevance to efforts to prevent violence in a broad sense as upholding the principles of justice, human rights, and protection of life as the embodiment of maqashid al sharia. In understanding several verses, it is often questioned that the interpretation tends to give priority to men and downplay metaphors. In fact, these verses do not mean to denigrate women, they only refer to social roles and roles based on gender (gender roles), even generally having a history of sabab al-nuzul, so they are very historical. Generally verses like this are intended to support and realize the general purpose (maqashid) of the essential verses (ushul) which are also the central theme of the Quran. Abstrak: Secara konsep, keberadaan agama sesungguhnya menjadi alternatif bagi terciptanya realitas tanpa kekerasan khususnya terhadap perempuan. Islam memperkenalkan konsep pencegahan kekerasan terhadap perempuan yang mengacu pada ayat-ayat subtantif (ushuliyah), sekaligus menjadi tujuan umum/dasar syariah (maqashid al-syariah). Dalam konteks kehidupan berumah tangga terdapat beberapa aturan dasar yang diketengahkan Al Quran sebagai jaminan kemaslahatan bagi seorang istri untuk terhindar dari tindakan kekerasan fisik maupun psikis dalam kaitannya dengan pemenuhan hak-haknya sebagai perempuan. Tulisan ini berupaya menganalisis dan menemukan gagasan kemaslahatan yang digariskan syariat dalam relevansinya dengan upaya pencegahan tindak kekerasan dalam makna yang luas sebagai penegakkan prinsip keadilan, hak asasi, dan perlindungan hidup sebagai perwujudan maqashid al-syariah. Dalam memahami beberapa ayat, sering dipermasalahkan penafsiran yang cenderung memberi keutamaan kepada  laki-laki dan mengecilkan perumpuan. Padahal sesungguhnya ayat-ayat ini tidak bermaksud  merendahkan kaum perempuan, ia hanya merujuk pada fungsi dan peran sosial berdasarkan jenis kelamin (gender roles), bahkan umumnya mempunyai riwayat sabab al-nuzul, jadi sifatnya sangat historis. Umumnya ayat-ayat seperti ini dimaksudkan untuk mendukung dan mewujudkan tujuan umum (maqashid) ayat-ayat esensial (ushul) yang juga menjadi tema sentral Al Quran.

ENGLISH PRONUNCIATION DIVERSITY PRODUCED BY INDONESIAN COVER-SINGERS: A CASE STUDY ON THE YOUTUBE CHANNEL
Authors: Utami Ismi Maulina
Published: December 2021

This study focuses on the pronunciation changes of the Indonesian cover-singers on YouTube. It is qualitative research by using documentation technique. There were three subjects of this study namely RM with song “Memories”, AH with song “Thank You Next”, and HD with song “Comethru”. At the first singer’s pronunciation, there were 26 mispronounced words and she did consonant deletion, vowel shift, vowel coalescence, consonant neutralization, consonant insertion, and metathesis. At the second singer’s pronunciation, there were 17 mispronounced words and she did consonant deletion, vowel shift, consonant neutralization, consonant insertion, assimilation, and diphthongization. At the third singer’s pronunciation, there were 12 mispronounced words and she did consonant deletion, consonant neutralization, vowel shift, vowel coalescence, and consonant insertion. These pronunciation changes occur because of the distinction between the phonological system of English and Bahasa Indonesia , and the Indonesian cover-singers still rely on the word’s spelling rather than phonetic sound. Regardless of these two reasons, there are also several similarities in the phonological system between English and Bahasa Indonesia, but the Indonesian cover-singers still perform the pronunciation changes.
El discurso de Iván Duque sobre el Acuerdo Final en el escenario internacional
Authors: Ríos Sierra Jerónimo , Morales Jennifer
Published: December 2021

Iván Duque siempre mantuvo una posición crítica ante el Acuerdo de Paz suscrito entre el Gobierno colombiano presidido por Juan Manuel Santos y la guerrilla de las Fuerzas Armadas Revolucionarias de Colombia (FARC-EP). Una vez que llega a la presidencia, en agosto de 2018, su política gubernamental, de acuerdo con todos los informes de seguimiento, ha estado caracterizada por incumplimientos, retrasos y dificultades. Así, el objetivo de este trabajo es analizar de qué modo el mandatario colombiano construye, dirige y modula su discurso en función del escenario en el que se encuentra. Metodológicamente, se revisaron los veintisiete viajes al exterior que ha protagonizado entre agosto de 2018 y diciembre de 2020, de manera que se analizan los contenidos de cada una de sus comparecencias, tal y como se encuentran recogidas en el portal de la Presidencia de la República. Al observar los informes de seguimiento al Acuerdo con las FARC-EP y las comparecencias en el exterior, es te trabajo explora y analiza las contradicciones reales entre el proceso efectivo de implementación y el discurso político que se proyecta. El resultado más relevante tendrá que ver con el marcado contraste existente entre la situación precaria del Acuerdo de Paz y un discurso en el que aspectos como la reincorporación, la noción de paz con legalidad o la reducción de los cultivos ilícitos aparecen como las prioridades más destacadas en sus intervenciones fuera del país.

Published: December 2021

Este trabalho propõe um procedimento para obter ganhos robustos de realimentação parcial de estados para controle das correntes de conversores conectados à rede com incertezas paramétricas. Controladores por realimentação parcial de estados permitem diminuir o número de sensores, produzindo respostas de boa qualidade com menor custo de implementação. Neste cenário, condições de projeto baseadas em LMIs podem fornecer resultados conservadores devido a restrições de estrutura (e.g., diagonal) que devem ser impostas nas variáveis de otimização. Em contrapartida, LMIs de análise são menos conservadoras e podem prover um certificado de estabilidade robusta do sistema em malha fechada de forma eficiente para um dado controlador. Como contribuição, é proposto aqui um procedimento de projeto para encontrar ganhos de realimentação parcial de estados otimizados, combinando uma meta-heurística com uma LMI de análise, para prover uma garantia teórica de estabilidade. Um estudo de caso mostra a vantagem da proposta em relação a LMIs de síntese para obter ganhos de realimentação parcial de estados. Resultados em tempo real mostram a superioridade do controlador proposto quando comparado a um controlador proporcional-integral da literatura. Resultados experimentais em protótipo de padrão industrial confirmam a viabilidade prática da proposta, com respostas em conformidade com a norma IEEE 1547.

Authors: Hidalgo-Fuentes Sergio
Published: December 2021

El presente estudio investigó las relaciones entre la autoestima, la soledad y el uso problemático del smartphone y las diferencias de género. La muestra fue no probabilística y estuvo compuesta por 202 participantes (106 hombres y 96 mujeres), con edades comprendidas entre los 18 y los 58 años, que completaron las siguientes pruebas: Smartphone Addiction Scale, Social and Emotional Loneliness Scale for Adults y Escala de Autoestima de Rosenberg. Se calcularon los estadísticos descriptivos, la prueba U de Mann-Whitney, análisis de correlación bivariados y dos modelos de regresión múltiple jerárquica. Se hallaron diferencias significativas entre hombres y mujeres en el uso problemático del smartphone. Además, también se encontraron diferencias en función del género en las relaciones entre las variables. Los análisis de regresión mostraron que, entre las mujeres, la autoestima y la soledad social son predictores negativos del uso problemático del smartphone, mientras que la soledad romántica es un predictor positivo. El presente estudio contribuye a un mejor conocimiento de las causas del uso excesivo del smartphone.
Riesgo suicida y discriminación en adolescentes y jóvenes marplatenses
Authors: Cordoba Paula , Oliva Camila , Galarza Aixa
Published: December 2021

El propósito de esta investigación fue estudiar la relación entre riesgo suicida y discriminación percibida en adolescentes y jóvenes marplatenses. Se realizó un estudio descriptivo, correlacional, transversal con un diseño no experimental y metodología cuantitativa. La muestra estuvo compuesta por 199 adolescentes y jóvenes de la ciudad de Mar del Plata. Se administraron el Inventario de Orientaciones Suicidas y una Encuesta de Discriminación Percibida. Los datos indicaron correlaciones significativas positivas entre las dimensiones de discriminación y las de riesgo suicida, con tamaños del efecto grandes. Estos resultados respaldan la hipótesis de que, a mayor percepción de discriminación total, habría un mayor riesgo suicida en la población encuestada, más allá de las dimensiones específicas de la discriminación —características físicas, diversidades sexuales, o aspectos socioculturales y económicos—. Tal como afirman los hallazgos, los adolescentes que sufren discriminación pueden experimentar depresión, temor, baja autoestima, aislamiento y sentimientos de rechazo, lo que afecta su desarrollo y su vida diaria, y puede favorecer la emergencia de ideaciones y planes suicidas.

Grain legumes are a valuable source of food proteins; hence, their exploitation is expected to grow in relation to a growing world's food needs. Apart from high level of dietary fibre, their protein composition makes them useful in managing diabetes. This paper reports a study conducted to evaluate the effects of four different non-soy legume-based (Vigna unguiculata ssp. dekindtiana var dekindtiana, Vigna unguiculata ssp. unguiculata, Sphenostylis stenocarpa and Vigna subterranea) diets in rats administered with alloxan monohydrate (150 mg/kg bodyweight). Concentration of plasma glucose, triacylglycerol, total cholesterol, HDL-cholesterol and HDL-triacyglycerol as well as hepatic levels of cholesterol and triacylglycerols were determined spectrophotometrically in alloxan-induced diabetic rats fed on these legumes for five weeks. Induction of rats with alloxan monohydrate led to significant (p<0.05) elevation of fasting plasma glucose and reduction in body weight. Consumption of each of the four legumes led to a significant reduction in the fasting plasma glucose concentrations in the diabetic rats (p<0.05) with V. subterranean causing about 60% reduction. Vigna unguiculata ssp. dekindtiana var dekindtiana and Sphenostylis stenocarpa caused a reversal of the diabetes-induced reduction of hepatic cholesterol (p<0.05). Plasma dyslipidemia was observed in the alloxan-induced diabetic rats as significant (p<0.05) increases in total cholesterol, triacylglycerols, HDL-cholesterol, HDL-triacylglycerols and LDL-cholesterol levels were observed. The legumes improved the plasma lipid profile as shown by a significant (p<0.05) reduction in the ratios of total cholesterol/HDL-cholesterol (ranging from 1.25-2.25 for control groups to 1.00-1.35 for the legume-fed groups) and LDLCholesterol/HDL-Cholesterol (ranging from 0.50-1.75 for control groups to 0.50-0.75 for the legume fed groups). The results suggest that wild cowpea, white cowpea, african yam bean and bambara groundnut equally reversed diabetes-associated dyslipidemia as indicated by the indexes of cardiovascular disorder. This, therefore, underscores the potential of these underutilized legumes in managing dyslipidemia associated with diabetes in experimental rats. These data should contribute toward enhancing the nutraceutical potential and utility of these legumes.

Authors: Murali Bellamkonda , Susheela R. , Shanti M. , Shailaja K. , Shashikala T.
Published: December 2021

Background: Long-term and stable livestock productivity could be possible only through a year-round supply of quality green fodder and it is essential for the sustainability of dairy farms. The year-round supply of quality green fodder is challenging to livestock farmers; however, it is possible by adopting perennial grass-legume intercropping systems. Methods: A field experiment with eight treatments consisting of two perennial grasses (Napier- bajra hybrid grass and guinea grass) alone or in combination with three fodder legumes (Lucerne, Hedge Lucerne and Sesbania) was conducted for 3 years (2016-17, 2017-18 and 2018-19) in a sandy loam soil at the Agricultural Research Institute, Professor Jayashankar Telangana State Agricultural University, Hyderabad. The treatments were replicated thrice in a randomized block design. Perennial grasses were raised in paired row method (row to row 120cm and plant to plant 60 cm. The legume intercrops were grown with their respective spacing within 120 cm row. Sesbania inter crop was allowed to grow for 6 months and later trimmed to a height of 1 meter in the establishment year. Growth parameters were measured only for grasses at each harvesting and green fodder, dry matter and crude protein yields were recorded for both grasses and legumes at each cut and accumulated annually (total 6 cuts/year) for statistical analyses. Result: The results indicated that among the grasses, Napier-bajra hybrid recorded significantly higher green fodder, dry matter and crude protein yields; in case of leguminous inter crops, Sesbania recorded highest green fodder, dry matter and crude protein yields followed by Hedge Lucerne. About total productivity of the system, Napier-bajra hybrid + Sesbania (2:1) cropping system recorded highest green fodder, dry matter and crude protein yields. Highest net returns and B:C ratio was also noted with Napier bajra hybrid +Sesbania (2:1) cropping system and proved to be the best perennial fodder system for year-round supply fodder to the livestock.

Dengue hemorraghic fever (DHF) is an infectious disease caused by the dengue virus and It is still be a major health problem in Southeast Asia, especially in Indonesia. Kabupaten Jember is still categorized as a dengue endemic area with its disease development expanding from year to year. This study aims to determine the correlation of platelet count and hematocrit levels to the severity of DHF patients at RSD dr. Soebandi Jember, as well as knowing whether the platelet count and hematocrit levels can be used as a predictive value for the severity of DHF patients at RSD dr. Soebandi Jember. This study used an observational analytic study with a cross-sectional study design. The data of this study used secondary data from the medical records of DHF patients at RSD dr. Soebandi Jember. The results of this study with a total of 68 samples showed that there was a significant negative correlation between the platelet count to the severity of DHF patients (p = 0,000, r = -0,487). The hematocrit levels showed an insignificant and negative correlation to the severity of DHF patients (p = 0,658, r = -0,055). The platelet count can be used as a predictive value for the severity of DHF patients.

Published: December 2021

Background: Surgery is one of the medical options for improving health. Surgery will break the main chain that causes health problems. Patients undergoing surgery will receive anesthetic management to relieve pain sensations. Pain sensations will be felt again after the period of anesthesia gradually disappears. Post-surgery clients will feel pain that varies widely. Purpose: This study aims to determine differences in the characteristics of postoperative client pain with general anesthesia and regional anesthesia. Methods: The method used was observational in postoperative clients with a cross-sectional design. Pain characteristics were observed after 4 hours postoperatively. Observation of pain used a pain characteristic observation sheet with observation items including pain intensity, pain onset, pain quality, and pain coping pattern. Observations were made on 30 postoperative clients with general anesthesia and 30 postoperative clients with regional anesthesia. The pain characteristics of the two groups after surgery were compared and the differences were seen. Result: The results of the study generally showed that the characteristcis of postoperative client pain with regional anesthesia (mean score = 18.1) were heavier than clients who received general anesthesia (mean score = 17.5). The results of the Mann Whitney test showed that the value of p = 0.000 (pain scale), p = 0.017 (pain time range), 0.000 (pain onset), p = 0.018 (pain intensity), p = 0.000 (pain depth), p = 0.000 (coping pattern). Conclusion: There are differences in pain characteristics between postoperative clients with general anesthesia and regional anesthesia on the aspects of pain scale, pain onset, the intensity of pain, depth of pain, and coping patterns of pain. The length of time of surgery and the level of depth of the surgical incision have a very significant effect on the characteristics of postoperative pain.

This paper analyses remotely sensed data over a part of the Psammitic Rocks in Efon-Alaaye and Environs to elucidate its geology and structural framework as well as delineate the potential zones of mineralization. The study area belongs to the Precambrian Basement Complex terrain of Southwestern Nigeria and lies within the eastern unit of the Ilesha schist belt. The lithologic units comprise schistose quartzites, quartz schists, quartz-mica-schists, and granitic gneisses. Landsat 8 satellite imagery and Shuttle Radar Topography Mission imagery (SRTM), both of path 190 and row 055, were used for the purpose of this study. A total of 138 lineaments of total length of 147.948 Km, were automatically extracted from both data. Rose diagram showed that the lineaments are bi-directional, with major lineaments trending NE-SW, E-W and the subsidiary ones in the NW-SE direction. These lineaments are mostly mapped on the schistose quartzites. Also, N-S trending faults were mapped from the Digital Elevation Model map generated from the SRTM data which was confirmed to be reverse fault based on field studies. The mineral alteration map generated revealed signatures of gold, iron oxides and silica minerals, while the mineralization potential map was done with reference to established geological settings of the area in conjunction with the structural elements such as folds, faults, joints and fractures mapped and measured on the field. These structures are typical of gold mineralization and associated metallic minerals in the Ilesha schist belt. This study also confirmed that mineralization in the study area is structurally controlled and type of mineralization is epigenetic in nature as a result of favorable ground preparation.

Terdapat kebijakan-kebijakan baru terkait pencegahan persebaran virus COVID-19. Beberapa kebijakan tersebut terkait sistem perkuliahan pada mahasiswa, yang dapat menyebabkan konsekuensi psikologis seperti kesepian. Dalam mengatasinya pertama diperlukan sikap dan hubungan sehat dengan diri sendiri, yang disebut sebagai self-compassion. Penelitian ini dilakukan pada 108 mahasiswa di Indonesia dengan usia 18-25 tahun yang saat ini melaksanakan perkuliahannya di kala pandemi COVID-19. Alat pengumpul data berupa kuesioner adaptasi UCLA Loneliness Scale Version-3 dan Self-Compassion Scale. Teknik sampling data pada penelitian ini adalah purposive sampling. Hasil penelitian menunjukan bahwa self-compassion memiliki pengaruh yang signifikan terhadap kesepian mahasiswa di kala pandemi COVID-19 dengan nilai koefisien sebesar R=0,514 (p<0,05). Koefisien determinasi (R2) self-compassion terhadap kesepian sebesar 0,264 yang berarti bahwa self-compassion menyumbang 26,4% faktor untuk memprediksi kesepian.
