DESIGN OF DEMERIT CONTROL CHARTS WITH FUZZY C-MEANS CLUSTERING AND AN APPLICATION IN TEXTILE SECTOR
Authors: YILMAZ Hülya , YANIK Seda
Published: May 2020

Companies use process control to detect and prevent defectrcts in production. One of the most commonly
used technique is control charts. To control multiple dimensions of quality on
one control chart, multivariable control charts, control charts for attributes
and demerit control charts are widely used. In this study, we use demerit
control charts to monitor multiple defect types and propose to employ fuzzy
c-means method to cluster the defect types based on pre-specified criteria. The
criteria are chosen to represent the severity of defect types and specified as:
(i) number of scraps, (ii) number of reworks and (iii) time of rework. In order
to test the proposed method, u and c attribute control charts and demerit
control charts for six instances in a textile company are used and compared. It
is observed that both the scrap and the repair rates are decreased when the
proposed method of demerit control chart is used.

Psychoactive substances, also called psychotropic substances, are products which have the ability to promote stimuli or sensory changes, influencing emotions and the level of consciousness of those who use them. The objective of this study was to analyze the use of psychoactive substances among medical students at the Federal University of Amapá (UNIFAP), Amazon region, Brazil, in 2018. A quantitative and qualitative cross-sectional study was used, which used a convenience sample, not probabilistic, of university students. At this university, among medical students, it was noted that the use of psychotropic drugs is mainly due to the use of alcohol and analgesics. In the medical context, due to the easier access to prescription drugs, their use is much wider in this audience of professionals and academics, and the use of such substances is sometimes hidden and there is a difficulty in talking about and seek assistance.

As substâncias psicoativas, também denominadas de substâncias psicotrópicas, são produtos os quais detém a capacidade de promover estímulos ou alterações sensoriais, influenciando emoções e o nível de consciência de quem as usa. O objetivo deste estudo foi analisar o uso de substâncias psicoativas entre discentes de medicina da Universidade Federal do Amapá (UNIFAP) em 2018. Foi realizado estudo transversal quantitativo e qualitativo, que utilizou uma amostra de conveniência, não probabilística, de estudantes universitários. Nesta universidade, entre os discentes de Medicina, notou-se que o uso de psicotrópicos se dá, principalmente, pela utilização de álcool e analgésicos. No contexto médico, por conta do acesso facilitado às drogas de prescrição, a utilização das mesmas é muito mais ampla nesse público de profissionais e acadêmicos, sendo que o uso de tais substâncias é, por vezes, ocultado e existe uma dificuldade em falar sobre e procurar auxílio.

Published: May 2020

Desa Pegayaman merupakan salah satu desa muslim tertua di Bali yang masih kuat dalam memegang tradisi nya. Pelaksanaan hari besar keagamaan serta tradisi-tradisi oleh umat Islam Pegayaman menciptakan ruang-ruang budaya di Desa Pagayaman. Seperti yang terlihat pada saat perayaan hari besar keagamaan Maulud Nabi yang memiliki arti penting bagi masyarakat desa dimana hari raya ini dirayakan secara meriah oleh masyarakat Desa Pegayaman. Ruang budaya tak hanya tercipta di skala mikro yakni hunian atau masjid , tetapi hingga ke skala makro kawasan dengan digunakannya ruas-ruas jalan sebagai bagian dari pawai Sokok. Ruang-ruang budaya ini memberikan ciri khas permukiman Desa Pagayaman. Hal ini sejalan dengan dengan yang dinyatakan oleh Dansby dalam Sasongko (2005) bahwa pembentukan suatu lingkungan permukiman pada dasarnya sangat ditentukan oleh berbagai faktor, diantaranya adalah budaya masyarakat setempat. Bagaimana individu berhubungan dengan keluarga dan lingkungan sekitarnya sudah tentu berbeda antara satu budaya dengan budaya lainnya, selanjutnya bagaimana ruang itu ditata dan dirancang sangat tergantung pada pandangan hidup masing-masing. Identifikasi ruang budaya yang terbentuk pada saat perayaan Hari Raya Maulud Nabi dilakukan melalui superimpose ruang-ruang budaya pada skala makro dan mezzo yang terbentuk pada rangkaian pelaksanaan hari raya sehingga didapatkan ruang budaya yang utuh pada Perayaan Maulud Nabi tersebut.

Authors: Suyoga I Putu Gede
Published: May 2020

Ngubeng merupakan salah satu cara berupacara umat Hindu dari tempat yang jauh dari lokasi pelaksanaan upacara. Ngubeng menjadi menarik dikaji di tengah pandemi Corona Virus Disease (Covid-19) saat ini, utamanya terkait dengan pemanfaatan ruang sosio-religius umat Hindu. Tujuan studi untuk membaca tanda simbolik praktik ngubeng sebagai solusi yang paling relevan dilakukan oleh seluruh lapisan masyarakat Hindu dalam menjalankan sradha dan bhaktinya kepada roh suci leluhur dan Tuhan dengan segala manifestasi-Nya saat ini. Studi kualitatif dengan metode deskriptif interpretatif ini melandasi analisis data dengan teori Proksemika atau Semiotika Ruang. Temuan studi menunjukkan teknik upacara ngubeng (tanda) secara tidak disadari telah membentuk struktur ruang mikro (penanda), yakni jarak sosial dan jarak publik yang sangat relevan dengan salah satu upaya pencegahan dan penanggulangan transmisi virus corona. Tanda simbolik ini bermakna mengarahkan pada physical dan social distancing yang aman bagi semua pihak dalam berinteraksi dalam ruang sosio-religius umat Hindu. Praktik ngubeng, jika dikaitkan dengan modul ukuran jarak pada tata ruang Arsitektur Tradisional Bali dan konteks pandemi Covid-19, modul kategorial jarak tersebut dapat dilipatgandakan (sekali, dua kali atau lebih), sesuai keperluan tingkat kegawatan wabah dan kewaspadaan sosial yang perlu dilakukan secara bersama-sama. Hal ini pada akhirnya akan membentuk struktur ruang makro antar teritorial desa, kecamatan, kabupaten, provinsi, pulau dan/atau negara.
ЗНАЧЕННЯ АКТІВ ЛОКАЛЬНОЇ НОРМОТВОРЧОСТІ В РЕГУЛЮВАННІ ПРАЦІ
Authors: Сіроха Д. І.
Published: May 2020

Стаття містить аналіз сутності актів локальної нормотворчості та їхнього впливу на правове регулювання праці. Автор розглядає концепції та підходи до локальної нормотворчості в доктрині трудового права. Стаття містить авторську концепцію значення локальної нор-мотворчості, яка сформована на підставі аналізу правових актів і результатів наукових досліджень. У статті зазначено, що до сфери локальної нормотворчості віднесено лише певні сторони трудових відносин, які відображають їхню специфіку на конкретному підприємстві (наприклад, встановлення правил внутрішнього трудового розпорядку, графіка робіт тощо). Локальні правові норми мають нормативний характер. Вони являють собою веління уповноваженого органу управління, спільні рішення роботодавця та профспілкового комітету, волевиявлення трудового колективу. Ці норми, закріплені в зазначених документах, є результатом відповідної правової спеціаліза-ції, встановлюються з метою конкретизації та деталізації, урахування своєрідності конкретних відносин. Особлива увага приділена правовій природі правил внутрішнього трудового розпорядку, технічних правил та інструкцій. Автор формулює своє бачення значення актів ло-кальної нормотворчості в регулюванні праці у трьох основних аспектах. По-перше, це прояв принципу демократичності трудових відносин, відповідно до якого потреби й інтереси працівника безпосередньо вплива-ють на нормативний зміст трудових відносин. По-друге, це засіб виховання правової культури працівника і роботодавця, а також їхньої взаємної відповідальності у трудоправових відносинах. По-третє, це реалізація вимоги правової визначеності, відповідно до якої суб’єктам трудових відносин має бути надана можливість легкого доступу до правових приписів, що визначають вимоги до їхньої поведінки, а також можливість використати локально-правові норми для захисту своїх прав та інтересів за необхідності.
Віртуалізація реальності як феномен культури сучасного інформаційного суспільства
Authors: Сащук Ганна Миколаївна
Published: May 2020

Визначено, що віртуальна реальність – це новий організований соціальний простір, який на противагу відображення реальної дійсності є джерелом  відмінності, заміщення, маніпуляцій, симулякрів - особливих об'єктів «відчужених знаків». З’ясовано, що важливою характеристикою віртуальної культури є її мозаїчність, пов'язана з особливостями процесу пізнання, а також структурування та ціннісного відбору соціального досвіду життєдіяльності. Як наслідок інтенсивного впровадження комп'ютерних інформаційних технологій у повсякденну культуру, безперервного і безладного потоку інформації, формується певний тип віртуальної культури, що поєднує в собі випадкові елементи культур різних народів та епох. Продемонстровано як дані елементи осідають за певними статистичними законами у свідомості індивідів, утворюючи щось на зразок «сховища повідомлень». Досліджено, що визначальною рисою віртуальної культури є побудований за принципом мультимедійного гіпертексту віртуальний простір, тобто специфічна організація інформаційних масивів, елементи яких пов'язані між собою асоціативними відносинами. Зазначено, що через специфіку просторової організації віртуальної реальності, у віртуальній культурі формується інша логіка мислення: нелінійна, непослідовна, недетерміністская, асоціативна. Ці ефекти досягаються завдяки моделюванню «іншого соціуму» та «іншого часу», відмінного від реального соціального часу - неодновимірного, оборотного, різноспрямованого і нескінченного. Підсумовується, що завдячуючи віртуальній реальності, не відбувається ціннісного відбору і структурування соціального досвіду, як у випадку спрямованого процесу пізнання, що реалізується за допомогою системи освіти. У цьому полягає основна відмінність віртуальної культури від культури в її традиційному розумінні в науці як ціннісно-відібраного та символіко-семіотично організованого досвіду багатьох людей.
ІДЕОЛОГІЧНІ ОСОБЛИВОСТІ ПАРТІЙНОЇ ПАЛІТРИ СУЧАСНОЇ УКРАЇНИ: АНАЛІЗ ПРОГРАМ ВІТЧИЗНЯНИХ ПАРЛАМЕНТСЬКИХ ПАРТІЙ
Authors: Кройтор Артем Вікторович
Published: May 2020

Статтю присвячено дослідженню політичної ідеології як чинника формування партійної системи України на підставі аналізу програм політичних партій України. Одним із важливих інститутів реалізації політичних ідей, перетворення їх у стратегію політичного розвитку держави є політичні партії, що презентуючи на виборах свої ідеології здобувають право їх реалізації за підтримки суспільства.
Партійна ідеологія базується на емпіричних світоглядно-методологічних формах суб’єктивного сприйняття політичної дійсності. Практичне вираження партійна ідеологія міститься у програмових та статутних документах політичних партій. Партійна ідеологія покликана виражати популярні у суспільстві політичні ідеї та цінності. В такому випадку парламентські вибори є механізмом не лише ротації еліти, але й відбору основних вимог у політичній системі, а отже і визначенням домінуючої політичної ідеології. У статті проаналізовано програми таких політичних партій, як «Слуга народу», «Голос», «Європейська солідарність», «Всеукраїнське об’єднання «Батьківщина», «Опозиційна платформа «За життя!». Визначено особливості партійних програм та їх ідеологічних складових. Доведено, що політичні партії України є партіями універсального типу з розмитими ідеологічними орієнтирами. Визначено, що новостворені політичні партії, подібно до «старих» залишаються лідерськими партіями, локомотивами рейтингу яких є їх лідери. Більшість партій за шкалою ліві – центристські – праві, є центристськими партіями соціал-демократичного спрямування, усі програми політичних партій, що здобули підтримку електорату, окрім «ОП – За життя» мають проєвропейське спрямування. Характерною особливістю таких партій як «Голос» та «Слуга народу» є медійність, віртуалізацій їх діяльності, відсутність розгалуженої організаційної регіональної структури. Важливою ознакою сучасних політичних партій залишається високий рівень ідеологічної мобільності та рецептивності, здатності до інтеграції окремих постулатів конкуруючих політичних ідеологій у програмі однієї партії.
What can urban design learn from changing winds? A case study of public space in Nanjing (1990s-2010s)
Authors: Xu Qiuxia , Xu Zhen
Published: May 2020

Climate is one of the prominent and persistent factors affecting the human habitat. During the recent urbanization, human society has left remarkable environment footprints including the macro- and micro- climates related to human settlement. It’s essential for urban planning decision-maker to contextualize people’s wellbeing in the public space and micro-climate changes. The adverse changes of micro-climate are usually related more to local developments than to global changes, with the causality relatively feasible to detect.
Characteristic of openness, the open spaces play an important role as outdoor relaxation and wind corridor, which is precious yet vulnerable assets for the citizens’ wellbeing. Agglomerated and unintentional developments inevitably change the wind patterns which potentially affect public life. A longitudinal study of such circumstance will provide knowledge and lessons for sustainable and salutary urban design.
Based on CFD simulation, this paper compared the static winter and summer airflows patterns of the Drum Tower area in downtown Nanjing during the period of 1990s-2010s. The results indicated that the wind pattern complexity increased gradually, the outdoor comfortability degraded dramatically in some areas, the environment inequity might be deteriorated too. The researcher suggests putting micro-climate issues firmly on the agenda of public wellbeing policy, involving various stakeholders in the assessment and urban design code with technical and social supports.
LEARNING the City: Beyond the Urban Diary
Authors: Wolfe Charles R.
Published: May 2020

My viewpoint towards understanding cities is ecumenical and immersive. We all experience urban life, and have associated expectations, however simple or complex. In democracies, informed representatives are said to advance the needs of their constituents. Basic human needs are similar, but how they are expressed and sorted in a chosen location are not, so places will vary based on blends and mixtures of expression. To understand the particulars of a city, we must understand associated and customized needs, as well as opportunities to provide them.
Achieving public health, safety and happiness will vary. Solutions may be similar, but not the same, and we need to understand—to see and feel—what these solutions, or ‘context keys’, look like from place to place. When considering customized ‘context keys’ for cities today, we must understand how each city or urban place varies from broad stereotypes. We should avoid one-size-fits-all solutions without community input.

Istraživanje obuhvaća vremenske granice od 1. rujna do 30. studenoga 2003. godine. Izabrana metodologija i primijenjene istraživačke metode usklađene su sa suvremenim istraživačkim trendovima koji se primjenjuju u sličnim medijskim istraživanjima i istraživanjima izbornih i političkih kampanja. Autori ukazuju na svu složenost proučavanja ove problematike koja zaokuplja pažnju recentne komunikološke i politološke znanstvene javnosti. Polazna istraživačka hipoteza u potpunosti je potvrdila predviđane istraživačke rezultate. Autorska istraživačka koncentracija usredotočena je na ispitivanje međusobnih korelacija između medijske zastupljenosti političkih opcija, osoba i izbornog građanskog ponašanja. Provedena je i induktivno-deduktivna analiza medijskog predstavljanja u korelaciji s utrošenim financijskim sredstvima za promidžbu i propagandnu kampanju. Dobiveni rezultati pokazuju da ne postoji značajniji uz-ročno posljedični odnos između medijske zastupljenosti i izbornog građanskog ponašanja. U zaključnom interpretiranju dobivenih rezultata je vidljivo da se stavovi o izbornoj preferenciji birača, prije izborne kampanje, nisu bitno izmijenili tijekom medijske promidžbene i propagandne izborne
građanske izloženosti.

LOAD BALANCING BETWEEN UNMANNED AERIAL VEHICLES OF A FLYING WIRELESS NETWORK USING AUTOMATIC REPLACEMENT AND CHARGING STATIONS
Authors: Kliushnikov I. , Fesenko H.
Published: May 2020

Today, multi-rotor UAVs (MUAVs) equipped with an electric motor are considered to be used as an affordable and cost-efficient tool to deploy flying wireless networks (FWNs). Nevertheless, the popular MUAVs have an endurance of about 30 minutes only. The last fact presents a significant barrier to use FWNs in complex, long-term missions. To overcome this problem, MUAVs can use shift schedule with a possibility for free schedule to be served at an automatic replacement and charging station (ARCS). After visiting the ARCS, MUAVs can either use the same route every new duty cycle or change the route.
The operation of a flying wireless network, consisting of five MUAVs and using one ARCS, is considered. The purpose of the flying wireless network is to organize the transmission of radiation monitoring data in the event of damage of the wired channel between a monitoring station and the crisis centre by creating: WiFi channel between the monitoring station and UAV of an aircraft type; LoRaWAN channel between AUAV and the crisis centre.
The following assumptions take place: the UAV of an aircraft type has sufficient flight time to complete the mission; five MUAVs periodically visit the ARCS; the location of the MUAVs within the flying wireless network during each subsequent cycle may be changed.
The problem of MUAV flight planning using the maximin criterion is formulated. It is shown that this problem can be transformed to the problem of finding the shortest path for each individual MUAV for load balancing between them.
The stages of implementation of the method of load balancing between the MUAVs of the flying wireless network are considered. The method requires adjusting flights routes for the MUAVs between the ARCS and the flying wireless network for each duty cycle. An example of the proposed method application to adjust flights routes for each of the three duty cycles is given.

WATER BALANCE AT PLANTS IN TECHNOLOGICAL SOLUTIONS ENGINEERING
Authors: Galkina О. , Degtyar М.
Published: May 2020

In this paper questions and conditions of water management in the water-circulation systems taking into account water losses on the example of the coke-chemical plant are considered. The water balance of the primary gas refrigerators cycle at the Kharkiv coke plant has been calculated and compiled, taking into account the proposed technological solutions. As a result of the operation of the water-circulation systems, it was found that the water loss for evaporation at the Kharkiv Coke Plant is on average 2% in winter and 3% in summer. Water losses in the system are replenished with fresh technical water and purified phenolic wastewater. Technical appraisal of the work of heat-exchange equipment at coke plants is carried out consists of replacing part of fresh technical water with phenolic wastewater and minimizing wastewater discharges. The purpose of the project is to create conditions for the water re-use by coke-chemical plants and to predict its water balance depending on the technological decisions made. Thus, the purge of the system is 5.6 m3/hour, while the total irreparable water loss in the system is 9.4 m3/hour. In the article it is established that the application of the proposed technical solutions allows to reduce the amount of discharge of sewage into urban sewer network at 36 000 m3/year and consumption of fresh industrial water to 52 000 m3/year, and increase the service life of equipment from 6.5 to 8 years. These measures help to improve water and environmental situation, effective water management of the coke-plant, that is, to decrease the payment made for consumption of water resources and sewage plant. The presented water balance and calculations of losses of water in the reverse water supply system of the enterprise are executed prove positive effect from the proposed technology solutions.

The relevance and timeliness of ensuring the territorial development of land use at the regional level is deter-mined. The aim of the study is to develop conceptual provisions and a methodological approach to determining and assessing the territorial development of land use in regions. To achieve this goal, the following tasks are solved: identification of problems in the system for ensuring the territorial development of land use in the regions; the formation of conceptual provisions for determining the territorial development of regional lands; development of a methodological approach to assessing the level of territorial development of land use. The problematic aspects are identified and a definition of the concept of «territorial development of land use in the region» is proposed. The directions of the development and implementation of a methodological approach to assessing the territorial development of land use in the regions are described. As a result of the study, an integral indicator of the territorial development of land use in the region was determined, the value of which indicates the need to change its trends by taking measures and developing scientifically sound recommendations for ensuring the territorial development of land use for the transition from a moderate scenario to a growth scenario.

VARIABLE METHOD FOR SEARCHING THE RATIONAL DESIGN OF BACK RETAINING WALL SURFACE
Authors: Khalife R. , Melish N.
Published: May 2020

The article presents the formulation and implementation of the variable task of finding a rational outline of the back face of a retaining wall. In the framework of the Coulomb theory, an analysis is made of a system consisting of a retaining structure and soil pressing on it for the possibility of formulating a rational design problem. The simplest example shows the possibility of formulating the problem of finding the rational geometry of the back face of a retaining wall within a given horizontal projection. The substantiation of the operation of the energy method of rationalization in solving the problem under consideration is given. The essence of the proposed method for finding the rational geometry of the back face of the retaining wall is to approximate the curved generatrix of the back face of the retaining wall with a broken line. For each broken section, key dependencies are derived for its effect on the nature of the stress-strain state of the structure, in particular, in the formulation under consideration, on the magnitude of the bending moment in pinching. Key dependencies are derived and an algorithm for solving the problem is described. An illustrative example shows that, given the characteristics of a loose granular moment, the moment of pinching can actually be described through a combination of the angles of inclination of each of the sections, and in general the form of such combinations is infinite. The problem is reduced to searching for such a combination αi, in which the introduced criterion (in the formulation under consideration, the moment in pinching) takes its lower value. The implementation of the approach is demonstrated by a numerical example.
The proposed approach allows a variable method to determine the surface configuration of the retaining wall, rational from the standpoint of the accepted criterion. The example given in the work clearly proves the correctness of the statement of the problem and its solution. The operation of this method is advisable in the computing information environment. In particular, the practical application of the presented approach is possible by formulating and solving the linear programming problem by the simplex method.
Keywords: Retaining wall, curvilinear surface, approximation, variational approach.

The problem of stability analysis for the general class of random pulsed and switching neural networks is presented in this paper, which is to be investigated both continuous dynamics and impulsive jumps of random disturbances. Two numerical examples are used to explain and highlight the effectiveness of the results developed. The purpose of this article is to provide a comprehensive overview of studies, including continuous time and discrete time models for solving various problems, and their application in motion planning and superfluous manipulator management, chaotic system tracking, or even population control in mathematical biological sciences. Considering the fact that real-time performance is in demand for time-varying problems in practice, analysis of the stability and convergence of various models with continuous time is considered in a unified form in detail. In the case of solving the problems of discrete time, procedures are summarized for how to discriminate a continuous model and methods for obtaining an accuracy decision.
Due to its strong ability to extract features and autonomous learning, neural networks are rooted in many industries, for example. neuroscience, mathematics, informatics and engineering, transport, etc. Despite their widespread use in various fields, such as artificial intelligence, language recognition, and computer simulation, the issue of neural network stability analysis is the most primary and fundamental that has attracted intense attention in recent decades. and references therein.

TRANSITION PROCESSES IN ELECTROMECHANICAL TRANSMISSION WITH A RESILIENT-ELASTIC COUPLING
Authors: Kindratskyy В. , Litvin R.
Published: May 2020

Driving systems for hybrid cars and electric vehicles equipped with electric motors have different structures and characteristics. In the vast majority of hybrids, depending on the driving mode, the torque on the wheels of the car can be generated separately by both the internal combustion engine and the electric motor, or by working together.
Based on the research results it is established that at the moment of starting the electric motor, the torque in the transmission sections steeply increases to 17 N•m, and for about 1 s decreases to the value of 7 N•m. In the period from 4 to 5.5 s, the torque increases to 14 N•m, which is explained by the overcoming of the inertial load during acceleration of the driven weight, and rapidly decreases to the value of 4 N•m, which corresponds to the consolidated moment of resistance to movement. The electromagnetic moment of electric motor thus also increases steeply in the initial stage of starting the motor up to 66 N•m and after 1 s decreases to the value of 15 N•m. After 5.5 s there is an increase in the moment to the value of 66 N•m and after 5.8 s it stabilizes and ranges from -6 to 22 N•m. In turn, the calculations for an electromechanical transmission equipped with a resilient-elastic coupling showed that the maximum torque in its sections Т2 during the start-up period decreased to 9 N•m, and the acceleration time to a steady turning velocity of the driven weight slightly increased to 6.8 s. The torque that occurs in the transmission sections during acceleration to a steady velocity does not exceed 13 N•m. The torque in the resilient-elastic coupling sections during the start-up period does not exceed 10 N•m, and its value, upon reaching the steady motion of the driven weight, is slightly less than 5 N•m. Peak torque in the resilient-elastic coupling sections Т1 reaches 22 N•m, while in the transmission Т2 it is 13 N•m, which confirms the efficiency of resilient-elastic coupling operation.
Thus, the use of resilient-elastic coupling in an electromechanical transmission can reduce the amplitude of the torque in the drive sections during the start-up period by about 1.9 times, as compared to the amplitude of the torque without resilient-elastic coupling, and reduce the peak torque of the transmission sections by 1.7 times.

Priority directions and measures among the main branches of urban electric transport are resource saving in the subway transportation system during its operation. First of all, this problem must be solved by scientific support, that is, at the stage of designing parts and components of vehicles. One of the main tasks that are solved at the design stage is to increase the load-bearing capacity of the parts by analyzing their stress-strain state. The article is devoted to the calculation of the load capacity reserve of the longitudinal beam of the front subway trolley under the action of evenly distributed over the entire length of the load without taking into account the transverse forces. The priority of the research topic is substantiated, the purpose and tasks are formulated. Two approaches to the power calculation of the bearing capacity of the longitudinal beam are introduced: the calculation of the permissible stresses and the limit state. In both cases elastic models of beams are considered. In the case of calculation on the limit state, the mechanics of the occurrence of plastic hinges at the places of rigid fixing of the ends of the beam are first substantiated. The beam still retains its load capacity. With the further growth of the external load, the emergence of a plastic hinge is justified even in the middle of the beam with the simultaneous loss of the beam of the bearing capacity. To simulate the behavior of the beam according to its characteristics, including the stress and the degradation condition of its load capacity, the mathematical formulation of the problem of calculating the load capacity of the longitudinal beam when calculating the permissible stresses and the limit state without taking into account the transverse force. The load-bearing capacity of the longitudinal beam in the calculation of permissible stresses and the limit state is analyzed. The analysis of the obtained results allows us to judge the effectiveness of the proposed mathematical model as a whole. The obtained equations for the maximum allowable load when calculating the limit state and the allowable stresses allow us to reliably estimate the bearing capacity of the longitudinal beam in both cases. The increase in the bearing capacity of the beam in the case of calculation on the limit is three times. The conclusions about the adequacy of the analysis of the bearing capacity of the longitudinal beam bearing capacity were made. Keywords: resource saving, beam, bearing capacity, allowable stresses, limit state.
The Role of Written Corrective Feedback in EFL Writing
Authors: Mamad Abderrahim
Published: May 2020

There is a great body of literature that indicates that writing is the most difficult language skill in language learning. Students often find it challenging to write a coherent, well thought and well accurate piece of writing because of the various aspects (organization, content, grammar, syntax, word choice) they need to satisfy while writing. For teachers of writing, what matters is not students’ mastery of all these aspects at once, but their ability to write a good piece of writing. This aim is really disregarded once the produced paper receives little or no feedback on students’ writing. Therefore, the proposed paper aims at outlining the different strategies and types of written corrective feedback that English foreign language (EFL) teachers employ to respond to students’ writings, focusing on the definitions, characteristics, advantages and limitations of each strategy and type. Suggestive dimensions of feedback provision and useful tips on implementing good feedback are also addressed.

Published: May 2020

Pattern and process of vegetation change (succession) were compared on two northern North Island
volcanoes: Whakaari (White Island) and Rangitoto Island where the endemic woody tree Metrosideros
excelsa is the primary colonizer of raw volcanic substrates. Quantitative data from our previous publications
(see References) and the references therein illustrate sequences of vegetation succession following
significant volcanic eruptions. New information on Rangitoto Island M. excelsa patch dynamics and updated
vascular species statistics for Whakaari have also been included. We also draw on supporting data from M.
excelsa forest on the mainland and long-inactive volcanic islands in the Bay of Plenty, to provide a context
for understanding the vegetation dynamics on Whakaari and Rangitoto Island. Species facilitation, light
availability, humidity, substrate and disturbance history are all key determinants of vegetation succession
across these volcanic landscapes.
The 2011-2012 El Hierro submarine eruption: a challenge of geochemical and thermal imaging for volcano monitoring
Authors: Pérez Nemesio M.
Published: May 2020

A shallow submarine eruption occurred between October 12, 2011 and March 5, 2012 about 2 km
off the southern coast of El Hierro, the youngest and smallest of the seven major islands of the Canarian
archipelago. This submarine eruption rose from a depth of 363 meters and finally reached 89 meters bsl
and provided us a unique chance to study a variety of precursory signals before the eruption as well as to
evaluate for the very first time magma emission rates from a shallow submarine eruption using airborne
thermal imaging.
Femininity and masculinity in Chinese culture
Authors: Huan Wang
Published: May 2020

n traditional Chinese culture, the concepts of femininity and masculinity are “plural categories” which are based on family and society, hence they are not clearly distinguished nor opposite to each other. In ancient times, people valued the power of women, channelling it by saying that women should devote themselves to benefiting the state. Meanwhile, society oppressed women by limiting them to their marital homes in order to eradicate men’s unconscious fear of the destructive side of feminine power. On the other hand, for Chinese men, sexual pleasure and aggression were unwelcome, while the mother–son relationship was most important within the family, and comradeship and brotherhood between men another important aspect of relationships. Profoundly mutual relationships were not encouraged between men and women in ancient China. Even until now, all men and women and their intimate relationships have been in the service of politics. The interests of the family and state are placed above individual interests. However, the one-child policy, as the product of government decision based on population numbers rather than human factors, and implemented by coercion, has produced a generation of empowered daughters and “little emperors” who increasingly value and appreciate individualism. The new generations must learn how to develop new forms of mutuality between the partners, with evolving implications for masculinity and femininity.

This experimental study was carried out to determine the antibacterial effect of Crude Ginger Extract (CGE) and Ethanolic Ginger Extract (EGE) against standard strain of Staphylococcus aureus in the Department of Pharmacology and Therapeutics with the collaboration of Department of Microbiology, Mymensingh Medical College, Mymensingh from July 2016 to June 2017. The growth of Staphylococcus aureus started to be inhibited from 70% CGE incorporated media and complete inhibition of growth occurred at 100% CGE. In case of Ethanolic Extract, sensitivity was seen against Staphylococcus aureus using disc diffusion method. Zones of inhibition were 8, 13 and 19 mm at 25, 50 and 100 μg/10 μl respectively. The minimum inhibitory concentration (MIC) of EGE was assessed by broth dilution technique. The MIC of EGE was 400 μg/ml against Staphylococcus aureus. From the study it is clearly observed that there is definite antibacterial effect of crude ginger extract (CGE) and ethanolic ginger extract against Staphylococcus aureus. Further studies are required to detect and isolate the active ingredients present in the Ginger extract responsible for antibacterial effect.

Published: May 2020

Background: Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of developing cardiovascular disease. Echocardiography (ECHO) carries information about cardiac diseases and prognosis in COPD patients.

Objective: To find out the Echocardiography changes in COPD patients and to assess Right ventricular (RV) dysfunction by echocardiography and correlate with the disease severity.

Methods: A prospective study was conducted on 70 patients admitted with symptoms and signs suggestive of COPD in the Department of Medicine, Gazi Medical College and Hospital (GMCH), Khulna from January 2017 to December 2018. Patients were diagnosed clinically as having COPD with confirmation by spirometry. The patients with asthma, bronchiectasis, tuberculosis, pneumoconiosis, restrictive lung disease like kyphoscoliosis, rheumatic, congenital, ischemic heart disease and hypertension were excluded from the present study.

Results: Regarding symptoms, majority 65 (92.9%) patients had breathlessness, 58 (82.9%) had cough with sputum, 25 (35.7%) had swelling of feet. Regarding signs, 68 (97.1%) patients had tachypnea, 24 (34.3%) had raised JVP, 23 (32.9%) had loud P2 suggestive of pulmonary arterial hypertension. Regarding echocardiographic findings, 42 (60.0%) patients had Cor pulmonale, 32 (45.7%) had LVDD, 31 (44.3%) had RVH, 30 (42.9%) had PAH, 29 (41.4%) patients had RA/RV dilation, 11 (15.7%) had RVSD and 9 (12.9%) had LVH. Table 08 shows RA/RV dilatation, RVH, Cor pulmonale, PAH and LVDD were statistically significant (p<0.05) when compared with severity of COPD. Conclusion: High occurrence of cardiac co morbidities such as PAH, RV dysfunction and LV dysfunction accompanied COPD patients. The severity of complications increased with severity of COPD which makes a linear relation. The 2D-echocardiography is more sensitive than radiography and clinical methods in detecting cardiovascular complications like PAH, ‘p’ pulmonale and RV dysfunction in COPD patients.

Published: May 2020

O sorgo granífero (Sorghum bicolor L.) é um cereal fortemente utilizado em alimentos processados por ser isento de glúten, devido a importância desse grão se faz necessário definir as condições seguras para armazenamento. Assim, objetivou-se determinar as isotermas de dessorção para os grãos de sorgo granífero. As isotermas de dessorção dos grãos foram obtidas pelo método estático-indireto, obtendo-se a atividade de água do produto nas temperaturas de 10, 20, 30 e 40 ºC, para a faixa de teor de água entre 14 a 24 ± 0,1% em base seca. Aos dados experimentais foram ajustados modelos matemáticos frequentemente utilizados para representação da higroscopicidade de produtos agrícolas. Para verificar o grau de ajuste dos modelos considerou-se a magnitude do coeficiente de determinação, do teste de Qui-quadrado, do erro médio relativo, erro médio estimado, critérios de informação de Akaike (AIC), e critérios de informação bayesiano de Schwarz (BIC).  Todos os modelos representam satisfatoriamente as isotermas de dessorção, no entanto segundo os parâmetros avaliados o modelo de Chung-Pfost foi o mais adequado. Para o armazenamento dos grãos de sorgo granífero o limite máximo de teor de água é de 15,69; 15,08; 14,53; 14,03% b.s., para as temperaturas de 10, 20, 30 e 40 ºC, respectivamente.
