KONSEP MANAJEMEN WAKTU DALAM SURAT AL ‘ASHR
Authors: Firdaus Firdaus
Published: June 2022

Manajemen waktu dalam pengertian sederhana adalah mengatur waktu. Manajemen pada prisinsipnya adalah mengatur waktu, mengorganisasikan, atau memanfaatkan waktu dengan sebaik-baiknya untuk aktivitas dan tujuan yang bermanfaat. Menurut Atkinson (1990) manajemen waktu adalah suatu jenis keterampilan yang berkaitan dengan segala bentuk upaya dan tindakan seseorang yang dilakukan secara terencana agar individu dapat memanfaatkan waktunya dengan sebaik-baiknya. Dalam surat al’Ashr ayat pertama Allah menjadikan waktu sebagai qosam (sumpah), Allah bersumpah demi waktu untuk menegaskan tentang penting dan berharganya waktu bagi umat manusia, kemudian pada ayat kedua Allah menggunakan ibarah dalam bentuk penekanan atau ta’kid lebih dari satu untuk menegaskan betapa berharganya waktu. Selanjutnya pada ayat-ayat berikutnya Allah mengajarkan sebuah konsep manajemen waktu yang luar biasa, bukan hanya sekedar memanfaatkan waktu untuk diri sendiri. akan tetapi, ayat ini mencoba untuk menjelaskan agar kita dapat memanfaatkan waktu untuk maslahat kita dan orang lain.

Pada penelitian ini penulis mencoba untuk menggali makna yang lebih dalam tentang konsep manajemen waktu yang dipaparkan dalam surat al ‘Ashr dengan pendekatan semiotika. Yaitu dengan menjelaskan konsep makna dasar atau makna denotatif dalam teori Roland barthes dan makna konotatifnya sehingga melahirkan satu interpretasi dan konsep baru dalam memahami manajemen waktu dalam Al-Qur’an.manajem

Abstract
Den sociala meningen med barns delaktighet i vårdnads-, boende- och umgängesprocesser
Authors: Wågby Angelica
Published: June 2022

Sedan barnkonventionens tillkomst har vi sett olika tolkningar av hur barns delaktighet ska förstås. Ett kritiskt perspektiv grundat i socialfenomenologi föreslås här som ett sätt att åskådliggöra förgivettaganden som finns inom både aktuella policys och teoretiska resonemang kring fenomenet barns delaktighet. Inom situationen för familjerättsliga processer avseende vårdnad, boende och umgänge i Sverige utforskas barns delaktighet som en fråga om dess intersubjektiva konstitution i den sociala livsvärlden och i den mångfald av subvärldar där delaktigheten förekommer. Det fenomenologiska förhållningssättet gör det möjligt att förstå vad vi menar med barns delaktighet i den familjerättsliga situationen och så sätt närma sig fenomenet utifrån en kritisk reflektion.

Artikeln skriver in sig i det mångdisciplinära forskningsfält som intresserar sig för ungas livsvillkor och kulturella uttryck i stigmatiserade bostadsområden i svenska storstäder. Under senare år har en mobilisering med krav på social rättvisa växt fram i dessa områden. I denna artikel undersöker vi innehållet i fyra poddar som kan betraktas som viktiga i denna sociala mobilisering. Studien har tre specifika syften, som också ringar in dess kunskaps­bidrag. För det första undersöker vi hur ortenpoddar, det vill säga poddar som handlar om orten och är producerade av unga därifrån, kan ses som uttryck för hur marginaliserade unga handskas med den rasifiering och underordnade klassposition som är en del av deras uppväxtvillkor. För det andra visar vår analys hur poddar fungerar som mötesplatser för unga i den marginaliserade förorten såväl som arenor för motstånd i form av motoffentligheter. För det tredje bidrar studien med kunskap om poddars folkbildande potential genom att analysera de folkbildande läroprocesser som kommer till uttryck i de utvalda ortenpoddar som utgör artikelns material.

Сокращение сроков доводки новых моделей судовых дизелей по-прежнему остается актуальной проблемой. Основная причина увеличения указанных сроков – это весьма существенное отличие расчетных и экспериментальных данных, полученных на испытательных стендах. В частности, по локальным тепловым потокам, передаваемым от рабочего тела к деталям камеры сгорания, упомянутое отличие составляет 25 – 50%. Это не позволяет на стадии проектирования с достаточной точностью задать граничные условия при расчетном анализе теплового и напряженно-деформированного состояния деталей, образующих камеру сгорания (крышки цилиндров, поршня и втулки) и влечет за собой значительное увеличение сроков экспериментальной доводки новых моделей судовых дизелей. Показано, что даже при использовании современных программных комплексов, в которых реализуются весьма сложные с физической точки зрения математические модели, требуется задавать некоторые параметры априори или пользоваться существующими экспериментальными данными. Целью данной статьи является представление 12 канального контрольно-измерительного комплекса, реализующего современные экспериментальные методики по определению параметров рабочего процесса и радиационно-конвективного теплообмена и позволяющего получить достоверные экспериментальные данные. Отмечено, что полученные с помощью этого комплекса экспериментальные данные могут составить надежную базу данных для проверки адекватности математических моделей, используемых конструкторами на стадии проектирования судовых дизелей.

It is shown that even in using modern programmers complexes in which mathematical models physical complex some parameters need to use experimental data or a priori. The purpose of this paper is presentation of 12 canal control measured complex that realized modern experimental methods in definition of parameters gases and radiative convective heat transfer and given reliable experimental data.

В работе представлены результаты экспериментальных исследований плоских решеток профилей с большим углом поворота потока. Представленные результаты являются продолжением исследований структуры потока в криволинейных каналах постоянного сечения с углом поворота 167 градусов. Рабочие колеса с таким лопаточным аппаратом входят в состав малорасходных турбин конструкции ЛПИ. Поскольку при исследовании единичных каналов большой изогнутости выявлены обширные зоны отрыва пограничного слоя, то в исследованиях ставилась задача определения способа профилирования плоской решетки профилей, ограничивающего влияние отрыва на потери кинетической энергии в решетке. Исследовались три решетки профилей с относительной высотой решеток l/B = 0,44; 0,58 и 0,87. Относительный шаг соответственно: t/B = 1,23; 1,63 и 2,45. Для измерения статического давления по обводу профилей лопатки дренировались. А для измерения углов выхода потока из решетки производилось траверсирование потока. Результатом исследований явились рекомендации по удлинению выходной кромки до четырех калибров, что снизило потери в решетке на 3%.

The paper presents the results of experimental studies of plane cascades with a large angle of flow rotation. The presented results are a continuation of studies of the flow structure in curvilinear channels of constant cross-section with a rotation angle of 167 degrees. Running wheels with such a blading are part of low-consumption turbines of the LPI design. Since the study of single channels with a large curvature revealed extensive zones of separation of the boundary layer, the research task was to determine the method of profiling a plane cascade, limiting the effect of separation on the motional energy loss in the cascade. Three cascades with a relative height l/B = 0.44; 0.58 and 0.87 were investigated. The relative step, respectively: t/B = 1.23; 1.63 and 2.45. To measure the static pressure along the contour of the profiles, the blades were drained. And to measure the angles of the flow out of the cascade, the flow was traversed. The research resulted in recommendations for lengthening the trailing edge up to four calibers, which reduced the loss in the cascade by 3%.

В районах морских портов, на морских и сухопутных трассах актуальной является задача учета и контроля различных транспортных средств. Для решения этой задачи всё чаще используются технические системы распознавания таких средств, использующие видеокамеры. Однако видеоизображения по ряду причин не всегда бывают высокого качества. Поэтому теоретический и практический интерес представляет задача распознавания транспортных средств по сильно загрубленным их изображениям – силуэтам. В нашем исследовании используется экспериментальный материал из репозитория данных UCI (UCI Machine Learning Repository) и предлагается трехкаскадный метод машинного обучения для решения этой задачи. В первом каскаде формируется множество прецедентов классов – объектов с привязанными к ним собственными локальными контекстно-зависимыми метриками, обеспечивающими прецедентам максимально возможную «сферу действия». На втором каскаде применяются методы поиска логических правил (корректирующих логических правил), для которых описаниями (признаками) объектов служат расстояния от определенных в первом каскаде объектов в их собственных локальных пространствах. В третьем каскаде производится организация взаимодействия корректирующих логических правил путем их ансамблирования. Вероятность правильной классификации транспортных средств составила P = 0,972 (для оценки применялся метод 10-fold кросс-валидации). Этот результат превзошел ранее известные результаты.

In the areas of seaports, on sea and land routes, the task of accounting and control of various vehicles is urgent. To solve this problem, technical recognition systems of such means using special sensors are increasingly used. However, video images are not always of high quality for a number of reasons. Therefore, the theoretical and practical interest is the problem of recognition of vehicles on their heavily coarsened images – silhouettes. Our study uses experimental material from the UCI (UCI Machine Learning Repository) data repository and proposes a three-stage machine learning method to solve this problem. In the first cascade, a set of class precedents is formed - objects with their own local context-dependent metrics attached to them, providing the precedents with the maximum possible “scope of action”. At the second cascade, methods of searching for logical rules (corrective logical rules) are applied, for which the descriptions (attributes) of objects are the distances from the objects defined in the first cascade in their own local spaces. In the third cascade, the interaction of corrective logical rules is organized by their ensemble. The probability of correctly classifying vehicles was P = 0.972 (a 10-fold cross-validation method was used for the assessment). This result surpassed previously known results.

Сжатие видео представляет собой непрерывный процесс передачи по каналам связи для решения двух важных задач: оперативной доставки в реальном времени и сохранении качества сжатых визуальных данных. В последнее время вопросы сжатия становятся более требовательным с точки зрения производительности за счет увеличения вычислительной сложности и, следовательно, потребляемый мощности устройств передачи изображений. Дискретное косинусное преобразование (ДКП) является наиболее распространенным механизмом, используемым в области сжатия изображений. В данной статье приводится новый эффективный алгоритм реализации ДКП для сжатия видеоинформации морских сюжетов с учетом свойств и высоты съёмки. Эффективность алгоритм заключается в учете статистических свойств исходного сигнала изображений при вычислении коэффициентов ДКП. Приведены результаты моделирования предложенного алгоритма и показаны оценки информационных показателей: коэффициент сжатия, структурного сходства восстановленных изображений и СИГ/ШУМ по сравнению с стандартными методами сжатия.

Video compression is a continuous process of transmission over communication channels to solve two important tasks: operational delivery in real time and maintaining the quality of compressed visual data. Recently, compression issues have become more demanding in terms of performance due to increased computational complexity and, consequently, the power consumption of image transmission devices. Discrete Cosine transform (DCT) is the most common mechanism used in the field of image compression. This article presents a new effective algorithm for the implementation of DCP for compressing video information of marine scenes, taking into account the properties and height of the shooting. The effectiveness of the algorithm consists in taking into account the statistical properties of the original image signal when calculating the DCT coefficients. The results of modeling the proposed algorithm are presented and estimates of information indicators are shown: compression ratio, structural similarity of reconstructed images and SIG/NOISE compared to standard compression methods.

Качество работы транспортной системы страны зависит среди прочего от эффективной системы оценки рисков транспортных происшествий и налаженной системы безопасности транспортного комплекса. Целью данного исследования является апробация комплексной математической модели оценки риска транспортных происшествий на водных объектах, учитывающей как чисто экологические последствия транспортных происшествий с судами, так и влияние этих происшествий на эксплуатационные и экономические показатели работы флота. Объектом анализа стали транспортные происшествия с сухогрузными судами. Комплексный риск транспортных происшествий прогнозируется путем произведения вероятностей столкновения с соответствующими последствиями. Среди источников убытков неэкологического характера автором были рассмотрены: потерянный фрахт в результате простоя судна; эксплуатационные расходы на ремонт; убытки от повреждения имущества на борту судна и убытки, причиненные гибелью или повреждением здоровья людей. Для учета этих факторов созданная ранее база данных была дополнена данными по простою судов, сроками проведения расследований, видами повреждений в результате транспортных происшествий. В результате выполненных исследований была создана классификация участков концентрации транспортных происшествий по уровню возможного риска с учетом факторов экологического и неэкологического характера.

The quality of the country's transport system depends, among other things, on an effective system for assessing the risks of such traffic accidents and an established security system for the transport complex. The purpose of this study is to test a comprehensive mathematical model for assessing the risk of transport accidents at river facilities, taking into account both the purely environmental consequences of transport accidents in an incident with ships, and the impact of transport accidents on the operational and economic performance of the fleet. The object of the analysis was transport accidents with dry cargo vessels. The complex accident risk is predicted by multiplying the collision probabilities with the corresponding consequences. Among the sources of losses of non-ecological nature, the author considered: lost freight as a result of the idle time of the vessel; maintenance costs; losses from damage to property on board the ship and losses caused by death or damage to human health. To take into account these factors, the previously created database was supplemented with data on the downtime of ships, the timing of TP investigations, types of damage as a result of transport accidents. As a result of the studies performed, a classification of areas with a concentration of traffic accidents was created according to the level of possible risk, taking into account environmental and non-environmental factors.

Обеспечение безопасного судовождения морских судов возможно путём разработки программных и программно-аппаратных средств, обеспечивающих контроль за окружающей такие суда обстановкой. В статье предложены три модели для оценки степени опасности столкновения морского судна с надводными объектами, встречаемыми на пути его движения. Модели отличаются входными параметрами - первая модель использует информацию о пеленге и дистанции, вторая – вычисляемую дистанцию и время сближения, третья – информацию о пеленге, скорости и курсе судна-цели, получаемые с радиолокационной станции. Каждая из моделей оперативно обрабатывает информацию с сенсоров для передачи в интеллектуальный блок, который принимает решение относительно необходимости осуществления манёвров расхождения с опасными объектами, обнаруженными на пути движения морского судна. Каждая модель исследована как в нечётком, так и в нейро-нечётком базисах. Для каждой модели проведено оценивание качества и проведено сравнение различных подходов к созданию моделей. Показано, что нейро-нечёткий подход позволяет практически однозначно определять степень опасности объектов для морского судна. Предложенные модели также целесообразно использовать при движении морских автономных надводных судов без экипажа на борту.

Ensuring safe navigation of sea ships is possible through the development of software and hardware tools that ensure control over the navigation condition surrounding such ships. The article proposes three models for assessing the collision danger degree rate for a sea ship with overwater objects encountered along the path of movement. The models differ by their input parameters - the first model uses information about bearing and distance, the second uses the calculated distance and approach time, and the third uses information about bearing, speed and course of the target ship obtained from the radar station. Each of the models processes information from sensors and transmit it to control unit, which makes a decision for passing with dangerous objects detected on the way of a sea ship. Each model was investigated in fuzzy and neuro-fuzzy bases. For each model, a quality assessment was done and a comparison of various approaches to model creation was carried out. It is shown that the neuro-fuzzy approach makes it possible to almost unambiguously determine the collision danger of objects for a sea ship. The proposed models are also suitable for use while navigating autonomous surface ships without a crew on board.

The quality of groundwater inan area is just as essential as the quantity. The groundwater quality of the Bemetera Block of Chhattisgarh State, in terms of domestic and irrigation use was studied. The hydrogeochemical evaluation, demonstrates that except of TH, SO42-, Ca2+, Mg2+, and Fe, all measured physical parameters in the study area fell within the Bureau of Indian Standards (BIS) limit. Further, certain sampling locations, such as S5 (Deep Aquifer), S9, S13, and S20, have a negative influence on drinking water quality as compared to others (shallow aquifer). Along with water quality analysis for the driking purpose, the irrigation water quality of the area was examined using several methods, and observed that most of the samples are suitable for domestic and irrigation purposes and some are not suitable.
Situation Analysis for Route Planning in Hilly Terrain

While travelling from one point to another in an unknown region, a user will come across many factors that would affect the move. If this move is in a threatened region, the factors affecting the move will be related to terrain and the situation. Thus, the information required for the move will be both natural and situational. Conventionally this information has to be analysed and converted to an optimum route. This would be based on analyzing the capability and experience of the individual. The natural or terrain factors can be known in advance and the situational factors have to be factored in dynamically. If the region is hilly, the slope will be the deciding factor for the shortest path along with the type of ground and the time of the move. Hence, natural factors have to be dovetailed along with situational factors to arrive at an optimum path. The intricate relationship between risk and time can be analysed with the help of the Risk-Time model. The relationship between all the factors being discussed can be found using a probabilistic model of the Bayesian network.

Rice bean acid phosphatase dialyzed against ethylenediaminetetracetic acid (1 mM), yielded no loss in activity at 0.5 mM p-nitrophenylphosphate. It had a mild activating effect at 0.1 mM p-nitrophenylphosphate. Divalent cations belonging to group II of Periodic Table like Mg2+, Ca2+, Sr2+, and Ba2+ at 0.5 mM concentration p-nitrophenylphosphate did not affect the enzyme activity. At 0.1 mM p-nitrophenylphosphate, however, only Mg2+ ions showed little inhibition. The transition metal ions viz. Zn2+ , Cu2+, Co2+, Mn2+ and Fe3+ showed inhibition at both pnitrophenylphosphate concentrations. Na+ , K+ , and NH4 + ions did not influence the enzyme activity, but Li+ inhibited the activity at 0.1 and 0.5 mM p-nitrophenylphosphate concentrations, respectively. Molybdate and phosphate anions proved to be strong inhibitors, but vanadate, a moderate inhibitor. Tartrate anion did not exhibit an effect on rice bean acid phosphatase. Sugars, plant hormones, medicines, vitamins, and amino acids at 1.0 mM concentration did not affect the enzyme activity. NADH exhibited the maximum activation, followed by citric acid, isocitrate, and oxaloacetate. Caffeine showed activation in the enzyme activity. Phosphate esters (1-Naphthylphosphate, phenylphosphate, PEP, and ADP) exhibited competitive inhibition when pnitrophenylphosphate was used as a substrate. Non-ionic detergents Triton X-100 and Tween-20 brought activation to the enzyme. The ionic detergent SDS brought complete loss to the enzyme activity. Dithiothreitol brought inhibition to the enzyme activity. The presence of β-mercaptoethanol did not influence the enzyme activity.

Liver cells (HepG2) were treated with well known toxic aromatic hydrocarbons 1-Naphthol and Dibenz[a,h]anthracene. Naphthol at 20-40µg/ml affected significant increase in the levels of reactive oxygen species in the cells.. Reactive nitrogen intermediates increased to an extent of 2.4 to 3.8 fold in cells treated with naphthol over a range of 20-80 µg/ml. Expression of antioxidant enzyme Glutathione peroxidase was found to increase two fold, while catalase expression was found to decrease by 21% on exposure to 1-Naphthol. Dibenz[a,h]anthracene did not affect discernible changes in the expression of these enzymes Induction of CYP1A1 mRNA by Naphthol at 60µg/ml was around 45 fold higher than untreated cells. Dibenz anthracene at a dose of 5µg/ml was found to be a potent inducer of CYP1A1 as it elevated expression of CYP1A1 mRNA to an extent of 350 fold. . Naphthol exhibited lipogenic potential in HepG2 cells. Concommitant increase in Sterol regulatory element binding protein 1c was observed.
