Nasal pathology as a cause of lacrimation in children
Authors: Karpishchenko Sergey A. , Rodneva Yuliia A. , Karpov Artemiy A.
Published: February 2022

Lacrimation or epiphora is one of the most common complaints in pediatric ophthalmic practice, indicating the presence of lacrimal duct obstruction. It is customary to distinguish between congenital or primary obstruction of the nasolacrimal duct the most common cause of lacrimation in newborns and children in the first year of life. Secondary or acquired dacryostenosis, characteristic of children from one year and older, most often has a rhinogenic origin, is more difficult to treat, and often leads to the development of complicated forms of the disease. Assessment of the cause of the epiphora is the key to making the correct diagnosis and choosing the optimal treatment tactics, conservative and/or surgical. A multidisciplinary approach, the interaction of an otorhinolaryngologist and an ophthalmologist is of great importance, which ensures the final successful result of lacrimation treatment in children.

Authors: Malyavskaya Svetlana I. , Kostrova Galina N. , Lebedev Andrey V.
Published: February 2022

Background. Vitamin D deficiency is common worldwide in all age groups, including children and adolescents, and is associated with adverse health outcomes. Evidence from observational studies indicates that vitamin D deficiency is associated with pathogenetic mechanisms of cardiovascular disease.
Aim. To assess vitamin D availability and prevalence of cardiovascular disease risk factors in adolescents and young adults.
Materials and methods. The cross-sectional clinical and laboratory study was carried out including schoolchildren aged 1015 years (319 subjects), of whom 49.2% were girls, mean age 13.31.6 years; young adults aged 1824 years (278 subjects), of whom 77% were girls, mean age 19.91.5 years, living in Arkhangelsk, Russia.
Results. The median level of 25-hydroxyvitamin D 25(OH)D in schoolchildren was 15.7 (12.219.2) ng/ml, in young adults 20.5 (14.926.9) ng/ml. The proportion of study participants with normal 25(OH)D levels (30 ng/ml or more) among schoolchildren was 1.6% and 19.0% among young adults. Both schoolchildren and young adults were found to have a high prevalence of cardiovascular risk factors. Proatherogenic metabolic abnormalities were found to be associated with low 25(OH)D levels.
Conclusion. The results obtained point to the necessity of implementing measures to prevent vitamin D deficiency in the groups indicated in the national program "Vitamin D Deficiency in Children and Adolescents in the Russian Federation: Modern Approaches to Correction".

NUMERICAL COMPUTATIONS OF GENERAL NON-LINEAR THIRD ORDER BOUNDARY VALUE PROBLEMS BY GALERKIN WEIGHTED RESIDUAL TECHNIQUE WITH MODIFIED LEGENDRE AND BEZIER POLYNOMIALS
Authors: Islam Nazrul , Asif Arefin Mohammad , Dhali Md. Nayan
Published: February 2022

Several different approaches are implemented and used to solve higher order non-linear boundary value problems (BVPs). Galerkin weighted residual technique (GWRT) are commonly used to solve linear and non-linear BVPs. In this paper, we have proposed GWRT for the numerical computations of general third order three-point non-linear BVPs. Modified Legendre and Bezier Polynomials, over the interval [0, 1], are chosen separately as a basis functions. The main advantage of this method is its efficiency and simple applicability. Numerical result is presented to illustrate the performance of the proposed method. The results clearly show that the proposed method is suitable for solving third order nonlinear BVPs
DERIVATION OF FORMULA OF APPROXIMATE IDEALIZED HYPHAL CONTOUR AS BUILT-IN HYPHAL FITTING PROFILE
Authors: Jaffar M.Z.A.M. , Ayop M.B.A.
Published: February 2022

Hypha consists of two regions; cap (apex) and cylindrical shaft (subapex and mature combined). The hyphal-cap is the most critical part due to its dominant role in the hyphal-wall growth and mor- phogenesis. Just how the hyphal-wall growth is regulated in order to maintain its tubular shape has been the subject of much research for over 100 years. Here, we derived a formula of approximate idealized hyphal-contour based on gradients of secant lines joining a fixed coor- dinate at the starting hyphal-shaft to any coordinates on the contour. The formula is capable of being a control for experimental analysis in which it is not limited to one specific shape of the hyphal-like cell. Also, it potentially can play a role as built-in or ready-made hyphal-fitting profile that “best fits” microscopic images of various actual hyphal- like cells. In other words, given a microscopic image of hyphal-like cell, mycologists and microbiologists would not have to wonder about mathematical representation of its contour since the formula has pre- pared for it.

Ekologi Akal Budi: Memahami Alam sebagai Kesatuan menurut Gregory Bateson
Authors: Tumanggor Bahtiar Jusuf Marulitua
Published: February 2022

While earth has been a living place for human beings, ecology crisis results from the speeding of human civilisation with its sudden jumps on science and technology. This crisis has caused damages in climate changes, global warming, and nature destructions. In spite of the changes in human behaviour, ecological crisis is also caused by epistemological crisis. Mechanistic paradigm leads humans to classify nature based on their own preferences. At the same time, positioning humans over nature brings humans’ hegemony. This article offers Gregory Bateson’s epistemological ideas to understand the unity between human beings and nature. Systemic paradigm can be used to sense nature as oneness of system that leads to the concept of sacrality of the earth. The concept of a sacred earth brings forth a systemic paradigm that shows nature as united with humans. Understanding sacrality as an intrinsic value of nature is a good epistemological start to maintain the ecological sustainability.
АКСІОЛОГІЧНИЙ ПІДХІД ДО ФОРМУВАННЯ ДУХОВНОЇ КУЛЬТУРИ МАЙБУТНЬОГО ВЧИТЕЛЯ
Authors: Білозерська С. І.
Published: February 2022

Стаття присвячена проблемі формування духовної культури майбутнього вчителя, яка значною мірою визначається рівнем педагогічної підготовки, прагненням до самовдосконалення в умовах професійної діяльності. Основоположним є твердження, що саме аксіологічний підхід до професійної педагогічної підготовки передбачає формування у студентів системи ціннісних орієнтацій, які визначають загальну спрямованість інтересів і прагнень особистості студента, а також розуміння цінностей духовної культури, що забезпечують цілісність та духовну зрілість особистості, прагнення до духовного саморозвитку, самоосвіти. Від характеру діяльності педагога, від його особистісних характеристик, ціннісних орієнтацій, життєвих установок та умов, які він створює, залежить не тільки якість засвоєння школярами встановлених освітнім стандартом знань, а й характер відносин суб’єктів освітнього процесу, атмосфера, в якій відбувається педагогічна взаємодія. Духовна культура майбутнього вчителя розуміється нами як складна, інтегративна якість, що виражається у високому рівні мотиваційно-ціннісного та морально-духовного ставлення до педагогічної діяльності, професійно-етичної вихованості, засвоєння морального досвіду та різних сторін духовного життя суспільства, у втіленні засвоєного в поведінці та професійній діяльності. Духовна культура педагога є показником особистісно-професійної зрілості та цілісності особистості; основою для створення власного ціннісного простору, який забезпечить освоєння базових цінностей життя та професійної діяльності. Здійснюючи змістовну інтерпретацію духовної культури, ми акцентували увагу на таких її складниках, як духовні знання, духовні цінності та духовне самовдосконалення. Духовні знання та цінності забезпечують формування у майбутніх педагогів здатності до самостійності, автентичної ціннісної орієнтації, заснованої на світоглядних рефлексіях, переживаннях, оцінках. Основними засобами духовного самовдосконалення є віра, любов, творення добра і боротьба зі злом, творення свободи і відповідальності, праця.
ОСОБЛИВОСТІ ОСОБИСТІСНОГО БЛАГОПОЛУЧЧЯ КУРСАНТІВ АКАДЕМІЇ ДЕРЖАВНОЇ ПЕНІТЕНЦІАРНОЇ СЛУЖБИ В УМОВАХ ПАНДЕМІЇ
Authors: Данильченко Т. В.
Published: February 2022

У статті йдеться про особливості особистісного благополуччя курсантів в умовах пандемії. Особистісне благополуччя розглядається як екзистенційний мультиконцепт, що відображає баланс між пошуком суб’єктом задоволення (позитивних емоцій) у різних життєвих сферах згідно з імпліцитною концепцією благополуччя та розкриттям особистісного потенціалу й досягнення гармонії між внутрішнім і зовнішнім світом, на основі базових емоційних характеристик особистості і позитивних рис характеру. Курсанти, що перебувають у специфічних умовах навчання, переживають тиск як із боку навчального закладу (акцент оцінювання і порівняння, нормованість та жорстка організація життєвого простору), так і з боку соціального середовища (контактні обмеження, пов’язані з пандемію COVID-19, дистанційне навчання). Тому перевірялося припущення про зниження благополуччя особистості. У дослідженні взяли участь курсанти Академії Державної пенітенціарної служби: 60 осіб (30 хлопців і 30 дівчат) у вересні – листопаді 2019 року, 106 осіб (43 дівчини і 63 хлопці) у вересні – жовтні 2021 року. Спостережені такі особливості. По-перше, рівень суб’єктивного (афективного) благополуччя не змінився («задоволений незначною мірою») – відбулася гедоністична адаптація. По-друге, виявлені статеві відмінності у змінах суб’єктивного соціального благополуччя. Не змінилася емоційна оцінка стосунків із близьким колом спілкування та пошук соціального схвалення в курсанток. У юнаків-курсантів підвищились значущість соціальних зв’язків та потреба в активній участі у групових процесах. По-третє, психологічне благополуччя зросло: до початку пандемії в курсантів, як юнаків, так і дівчат, воно було нижче, ніж в її активний період. Особливі зміни стосувалися розуміння життєвих цілей – відбулася актуалізація побудови життєвих планів у ситуації пандемічної невизначеності. Також зафіксоване підвищення показників особистісного зростання та компетентності, оскільки ситуація пандемії дала можливість отримати новий досвід і віднайти більш ефективні форм поведінки. Рівень переживання загального особистісного благополуччя статистично достовірно підвищився: особи з його високим рівнем становили 25,8 % до пандемії і 38,7 % під час її перебігу.

Authors: Bambang Hari Prabowo
Published: February 2022

Korosi merupakan gejala dan proses destruktif yang terjadi pada setiap peralatan yang terbuat dari logam paduan besi maupun non besi. Logam baja yang banyak digunakan sebagai bahan konstruksi pada saat mulai diaplikasikan langsung mengalami proses korosi. Korosi merupakan proses alami yang bersinggungan dengan lingkungan dan reaksi elektrokimia. Sehingga proses dan laju korosi pada kenyataannya tidak dapat dihentikan selama bersinggungan dengan lingkungan. Metoda yang selalu dilakukan selama ini adalah mengendalikan korosi dengan cara menghambat laju korosi misalnya dengan coating, proteksi katodik, inhibitor dan lainnya.

Zeolit adalah batuan anorganik atau mineral yang merupakan senyawa alumina silikat terhidrasi, yang mempunyai kemampuan sebagai penjerap, katalis dan penukar kation. Berdasarkan kemampuan ini, kami melakukan percobaan bahwa partikel zcolit mampu sebagai inhibitor penjerap dan melakukan pertukaran kation. komponen utama struktur zeolit adalah (SiO4)-4 yang membentuk struktur 3 dimensi, sehingga muatan listrik yang dimiliki oleh kerangka zeolit baik yang dipermukaan maupun di dalam pori mampu berperan sebagai penjerap dan penukar kation.

Metoda yang digunakan cukup sederhana yaitu dengan cara perendaman benda kerja (baja karbon) selama 720 jam (30 hari) dalam lingkungan asam dan basa, dengan konsentrasi 4 M dan 2 M. Penambahan partikel zeolit ukuran 0,75 mm sebanyak 20 g/ 500 ml larutan asam/basa.

Published: February 2022

A total of 10 bacterial isolates have been isolated from the gut of termites (Isoptera: Rhinotermitidae and Termitidae) and are known to have the ability to produce lignocellulolytic enzymes consisting of cellulase, laccase, and lignin peroxidase. The enzymatic ability allows these bacteria to be used as a source of new enzymes in the industrial world. However, further research on the character of bacteria to support identification has not been carried out. This study aims to characterize lignocellulolytic bacteria in the gut of termites morphologically and biochemically. Morphological observations were carried out including colony shape, colony edge, colony color, growth type, bacterial cell shape, and gram staining. Meanwhile, the biochemical characterization carried out included glucose fermentation test, indole formation, starch hydrolysis, catalase test, and nitrate reduction. The results showed that ten isolates of lignocellulolytic bacteria from the gut of termites (Isoptera: Rhinotermitidae and Termitidae) grew facultatively anaerobic, had almost similar morphological characters, with colony shapes including irregular and filamentous, colony edges in the form of lobate, undulate, and filamentous, and coloration. Colonies are white to yellowish white. The result of gram staining showed that most of the bacteria were gram positive bacteria with coccus and bacillus shaped bacterial cells. Biochemical analysis showed that these bacteria have the ability to ferment glucose, hydrolyze starch, reduce hydrogen peroxide (HÃ¢ââOÃ¢ââ 30%) and reduce nitrate.ÃÂ

Published: February 2022

Fertilizer substitutes elements that have been used by plants. There are two available fertilizers, inorganic and organic fertilizers. Long-term use of inorganic fertilizers on a land negatively affects the crop and the soil fertility, hence, the organic one is a better choice. This study aims to determine the effect of liquid organic fertilizer of banana peels on the growth of red spinach and determine the best treatment for red spinach growth. This study used a Completely Randomized Design consisted of 2 factors (dosage of POC banana peel and length of fermentation time). Each has 4 levels, 3 replicates. The results of data analysis using ANOVA test show that the treatment of fermentation length and dosage of POC banana peel increase growth parameters of red spinach include plant height, leaf number, leaf area, fresh weight, and dry weight, while the interaction treatment of fermentation length and dosage of POC banana peel affects almost all growth parameters, except for the leaf area parameter that shows no interaction. DMRT (ÃÂ± 5%) test shows that the best combination treatment for plant height and fresh weight is a dosage of 8 ml POC of banana peel that have been fermented for 15 days, and the best treatment for leaf number and dry weight is a dosage of 8 ml POC of banana peel that have been fermented for 10 days.

Published: February 2022

Potatoes are one of the foodstuffs that contain lots of carbohydrates, minerals, and vitamins. To develop potato cultivation, superior varieties are needed that produce high yields, are resistant to pests, and have good tuber quality. The growth of potato plantlets in the in vitro subculture process is determined by many factors, one of which is the administration of growth regulators and the concentration of growth regulators. The type of media or nutrients used also affects the growth and development of the explants and seedlings produced. This study aims to trigger the growth of potato plantlets so that their growth is optimal. The method used is a true experimental quantitative method with a one-factor Completely Randomized Design (CRD) design, namely variations in BAP concentration consisting of 5 treatments with 5 replications. Data collection techniques through observation or observation. Parameters observed were number of shoots, number of leaves, number of roots, and plantlet height. The data analysis technique used is the one way ANOVA test and for the average difference between treatments, the HSD (Honestly Significant Difference) test at 5% level is used. Based on the results of the study, it was known that there was an effect of giving the hormone BAP (6-Benzyl Amino Purine) on the growth of potato axillary shoots (Solanum tuberosum L.) in vitro. The results showed that there was a significant effect on the number of shoots (P = 0.007) with an average of 1.64 pieces, the number of leaves (P = 0.002) with an average of 1.42 pieces, the number of roots (P = 0.000) with an average of 1. an average of 1.70 pieces, and plantlet height (P=0.000) with an average of 2.65 cm. It was concluded that treatment D (1.5 ppm BAP) was the best treatment in increasing the growth of potato plantlets.

Published: February 2022

During the nesting season, green turtles have an instinct to return to their original place to lay their eggs. The success of turtle egg laying is influenced by the suitability of the beach for their nesting habitat which consists of physical and biological factors. The purpose of this study was to determine the suitability of the physical and biological factors of green turtle nesting habitat and its relationship to the number of green turtles landed at each station. The research method used is observation, the observation station is determined by purposive sampling, and the data analysis technique used is quantitative. The result is that physical and biological factors consisting of beach width and slope, sand texture and temperature, and vegetation at each landing station on Pangumbahan beach are still suitable as green turtle nesting sites except station 6. There were 47 green turtles that landed, and station 2 has the highest number of turtles landing, which is 16 turtles. Meanwhile, at station 6, no turtles landed. From the results of the correlation analysis, the beach slope factor and the vegetation density factor have a very strong and significant relationship with the number of turtles that landed. As for the other factors have a fairly - strong relationship. The conclusion is that all factors, both physical and biological factors from the beach, affect the number of green turtles that land, as evidenced by the relationship between the two variables.

Utilization of Turi leaves (Sesbania grandiflora) and cassava tubers (Manihot esculenta) as a protein source to replace some fish meal can be done by silage of the two ingredients. This silage fermentation process requires adding inoculum from the fermented liquid to obtain good quality silage. This study aims to determine the effect of fermented liquid on the quality of silage made from Turi leaves and cassava tubers for fish feed ingredients through parameters of Titration End Point and pH levels. The research treatment was the addition of fermented liquid for four days with a sugar content of 1% (CT4-1%) in the treatment silage (S_CT4-1%), compared to the initial silage (SA) and the negative control silage (SKN). The results showed a significant (P<0.05) addition of CT4-1% fermented liquid, namely Titration End Point S_CT4-1% a significant increase of 281.9% from 18.33 mL in SA to 70.00 mL in treatment. The pH condition significantly decreased from 5.35 in SA to 4.17 in the treatment. Titration End Point on SKN only increased by 90.9% from 18.33 mL to 35.00 mL, with pH only dropping from 5.35 to 4.31. Study concuded that CT4-1% produced excellent quality silage of Turi leaves and cassava tubers based on TAT and pH levels. This quality can increase the chance of silage of Turi leaves and cassava tubers treated with CT4-1% as a partial substitute for fish meal in fish feed manufacture.

Catfish have become an important contributor to fish production in Indonesia. Catfish consumption in Indonesia always increases every year. To meet the demand for catfish consumption, it was carried out with an intensive aquaculture system. However, the high cost of feed has been identified as a significant constraint in catfish farming. Efforts to increase catfish growth are needed to reduce feed costs, one of the efforts is by probiotic supplementation through the feed. This study was carried out to determine the best dose of probiotic rabal dried addition to increasing catfish growth. The experiment used four treatments and three replications. Probiotic rabal dried doses: 0% of feed (A)/feed (control), 5% of feed (B), 10% of feed (C), and (D) 15% of were used as treatment. The feed was given ad-satiation with a frequency of feeding three times a day. Observations were made for 45 days. The results indicated that the B treatment of 5% of feed gave the best absolute weight growth and feed conversion ratio. While catfish fish survival rate was not significantly different on all treatments.

Pembenihan belut sawah, Monopterus albus (Zuiew, 1793) belum dapat dilakukan karena terbatasnya teknologi. Pembenihan belut sawah dimulai dengan pemilihan calon induk jantan dan betina dengan mengembangkan metode praktis untuk membedakan jenis kelamin berdasarkan perbedaan morfologi tubuh. Penelitian dilakukan untuk mengidentifikasi perbedaan morfologi belut sawah jantan dan betina dengan metode morfometrik truss. Seratus ekor belut sawah jantan dan betina digunakan dengan mengukur 18 karakter fenotip pada bagian kepala, badan dan ekor. Hasil penelitian menunjukkan terdapat sepuluh karakter fenotip yang dapat digunakan untuk membedakan antara belut sawah jantan dan belut sawah betina. Lima karakter fenotip dapat menunjukkan belut sawah jantan lebih besar ukurannya dibandingkan belut sawah betina terutama pada bagian tubuh anterior nostril, panjang dari ujung depan rahang atas sampai posterior nostril, ukuran lebar mulut, panjang badan dan panjang total. Adapun belut sawah jantan lebih kecil ukurannya dibandingkan belut sawah betina pada panjang dari sudut bukaan mulut sampai belakang pangkal operkulum, panjang rahang atas, panjang kepala, lebar badan bagian vent dan panjang ekor. Secara praktis, bagian ventral-dorsal kepala menjadi penanda belut sawah jantan dengan lebar mulut lebih dalam dan rahang yang lebih kekar. Sedangkan belut sawah betina dapat diketahui dari bagian ekor yang lebih panjang yang diduga berkaitan dengan persiapan rongga untuk perkembangan gonad saat dewasa. Bagian badan tidak dapat dijadikan penanda untuk perbedaan jenis kelamin belut sawah.
