The manual use of household lights poses a problem in the efficiency of electricity use. Humans with various activities often do not pay attention to the condition of the lights in the room whether it lights up or not. This is certainly a waste of electricity when they leave the room without turning off the switch. Therefore, researchers propose an automation system that can save electricity from lighting. In designing the system there are two sensors used, namely Passive Infra-Red (PIR) sensor and Light Dependent Resistor (LDR) sensor. PIR functions to detect the presence of human movements (objects) in the sensor work area, while the LDR sensor functions to detect the intensity of light around the room. The results of the system testing are that the PIR sensor works well around ± 2 minutes after the device is activated and the LDR Sensor will continuously measure the value of light intensity then turn on and off the light according to the programmed command.

Published: July 2019

Motorized vehicles are one of the most widely used means of transportation in everyday life by the community. Engine performance is supported by the presence of an engine that complements the vehicle's performance due to the engine as a lubricant in motorized vehicles. In motorized vehicles, it is often found that engine problems are quickly hot when used by drivers when traveling long distances and even when stuck in traffic. To overcome this problem, an Oil Breather System will be added to the vehicle by punching a hole on the right side of the engine and planting a nipple for the hose holder Oil Breather System. From that point on, the oil will flow quickly directly from the oil pump. The oil is then passed on the hose to the Oil Breather System. From there the oil is cooled by gusts of wind received by the Oil Breather System and proceed to the Oil Breather System hole. Therefore, the Oil Breather System was installed in motorized vehicles. With the installation of the Oil Breather System in the Cover Valve section, the Cover driven chain air heat temperature on the 2012 Yamaha Mio-J vehicle engine can be reduced by a temperature of 5 ° C. This research will continue for other types of vehicles.

The tip voltage is determined by the distance of the distribution and the amount of load. The form of configuration also affects the amount of power loss and voltage loss. So that a good configuration is needed in order to obtain good efficiency. Reconfiguration of the distribution network is used to reset the network configuration form by opening and closing switches on the distribution network. Reconfiguration is expected to reduce power losses and improve distribution system reliability. Many feeders and buses on the network if calculated manually will be difficult and require a very long time. So it is necessary to solve problems using program assistance. In this case, use Particle Swarm Optimization (PSO). Particle Swarm Optimization (PSO) algorithm based on the behavior of a herd of insects, such as ants, termites, bees or birds. BPSO is a development of the PSO algorithm designed to solve the optimization problem in a discrete combination, where the particle takes the value of binary vectors with length n and speed which is defined as the probability of xn bits to reach value 1.

Published: July 2019

Introduction: Monte Carlo (MC) is considered to be the most accurate method to calculate dose distribution in radiation therapy. However, the limitation of MC simulations is the long calculation time to reach the desired statistical uncertainty in the dose calculation as well as in clinical practice. To overcome the above limitations, Variance reduction techniques (VRTs) has developed and shorten the calculation time while maintaining accuracy. Therefore, the purpose of this study is the application of VRTs in code EGSnrc to find the optimal method for accelerator simulation and calculated dose distribution using MC method.

Methods: The linear Accelerator HPD Siemens Primus at the General Hospital of Dong Nai had been simulated by using BEAMnrc code and several variance reduction techniques such as: range rejection, photon forcing, bremsstrahlung photon splitting (uniform, selective and direction)... These VRTs were used under the same set of input parameters as histories of 2x108, photon energy of 6 MV, structure, size and material of the phantom… The computational efficiency ε is calculated by the following equation ε = 1/T.σ2 where T is the CUP time of calculation and  σ2 is an estimate of the variance, for evaluating and selecting the VRT which gives the best computational efficiency.

Results: The results showed a good agreement between the calculated dose and measured ones when applying different VRTs. These techniques were significantly reduced uncertainty in simulation compared the analog cases. Specifically, the efficiency of DBS and UBS improved by more than 90 times and 15 times compared with the analog instances, respectively. Rang rejection and photon forcing techniques also haveimproved the efficiency of simulation, but not significantly.

Conclusions: The application of the VRTs for EGSnrc increase the efficiency of the simulation. VRTs is a powerful tool that should be applied for the simulation by code EGSnrc to improve calculation efficiency by reducing simulation time and its variance. Our results show that the direction bremsstrahlung splitting (DBS) gives thebest computational efficiency.

geliştirilmesinde topsuz yapılan koşular ve interval çalışmalar önerilmektedir.
Fakat futbolcuların topsuz yapılan bu tip çalışmalara yönelik görüşleri henüz
netlik kazanmamıştır. Bu araştırmanın amacı; futbolcuların topla ve topsuz
yapılan antrenmanlarla ilgi görüşlerini belirlemektir. Yapılan araştırmaya
Afyonkarahisar ilinde bulunan ve süper amatör kümede oynayan yüz kırk beş
futbolcu (yaş: 22.70±4.53 yıl; antrenman yaşı: 8.94±2.01 yıl) katılmıştır.
Araştırmada futbolcuların demografik bilgilerinin yanında, topla ve topsuz
yapılan antrenmanlarla ilgili görüşlerinin belirlenmesine yönelik sorular
sorulmuştur. Futbolcuların %17’si topsuz antrenmanı sevmediğini, %9.7’si ise
nefret ettiğini bildirmiştir. Bunun yanında %24,1’i normal şiddete ve sürede
topsuz antrenmanı tercih ederken, %75.9’u daha yüksek şiddette ve uzun sürede
topla yapılan antrenmanı tercih edeceğini bildirmiştir. Sonuç olarak
futbolcuların topla yapılan antrenmanlarda antrenmanın şiddeti yüksek ve süresi
uzun olsa da topla yapılan antrenmanları daha fazla istedikleri görülmüştür.
Literatürde topla yapılan dar alan oyunları ve drillerdeki yüklenme şiddetinin
topsuz antrenmana göre daha yüksek olduğu bildirilmektedir. Futbolcuların topla
yapılan çalışmalara olan isteklerinin motivasyon aracı olarak kullanılması ile
antrenman sayısının düşük olduğu amatör takımlarda çalıştırıcıların
futbolcularda fiziksel, teknik ve taktik özellikleri kombine bir şekilde
geliştirebilmeleri için doğru şekilde planlanmış topla yapılan dar alan
oyunları ve drilleri kullanmaları önerilmektedir.

Obezite ve fazla kilo alma durumu her geçen gün daha
fazla insanı etkilemekte ve toplumu tehdit eden bir sağlık sorunu haline
gelmektedir. Kilo vermek isteyen insanların doğal ve bitkisel ürünlere olan
ilgisi gün geçtikçe artmakta çeşitli etki mekanizmalarıyla kilo kaybına yol
açtığı düşünülen kafein de bu ürünler içerisinde yerini almaktadır. Bu çalışma
da çeşitli arama motorlarında (scholar, pubmed, web of science ve ovid) kafein
ve obezite üzerine yapılan çalışmalar incelenerek geleneksel derleme yöntemi
ile kafeinin obezite üzerine etkisi incelenmiştir. Son zamanlarda yapılan
araştırmalarda, yüksek kahve alımının, tip 2 diyabet, kardiyovasküler hastalık,
bazı kanser türleri, parkinson hastalığı ve mortalite riskinin azalması ile
ilişkili olabileceği sonucuna varılmıştır. Obezitenin,  belirtilen tüm bu sağlık risklerinin altında
yatan başlıca nedenlerden biri olduğu göz önüne alındığında, kafein alımının obezite
riskinin azalmasıyla ilişkili olabileceği düşünülebilir. İncelenen çalışmalar
neticesinde ılımlı bir kahve tüketiminin sağlıklı bir beslenme ve diyet
programında kilo kontrolü amacıyla kullanılabileceği değerlendirilmektedir.

Intellectual Capital in light of Creativity and Competitiveness: Overview of Organizations’ Intangible Assets.
Authors: Yousef Areiqat Ahmad
Published: July 2019

This research paper addresses several issues related to intellectual capital including a historical overview, the interest in elusive and intangible assets, and the impact of latest technological progress associated with the information technology developments. Ralph Stayer, CEO of Johnsonville Foods Company was the first to use the term “intellectual property” to refer to the organization’s intangible assets. This paper also identifies the concept of intellectual property being a set of all knowledge capacities of the organizations that help them achieve their goals. The intellectual property includes ideas, inventions, technology, general knowledge, computer soft wares and programs, designs, data skills, processes, creativity and applications in all organizations. The intellectual capital is knowledge that can be converted into profits. The components of this concept were identified as follows: Structural capital, human capital, social capital and the psychological capital. The paper also discusses various definitions provided by several researchers relating to intellectual capital, amongst them: Edvinsson & Malone, K. E. Svieby, Y. Malhorta, T. Stewart, Despres & Channvel, and Mckenzie & Winkelen. Moreover, the researcher tackled different measures used in intellectual property assessment and classified them in the following clusters: (1) descriptive measures/scales that describe some traits and characteristics and are based on exploring views related to identify the impact of the intellectual capital on organizations’ business (2) scales and models correlated to the intellectual capital and the intellectual property, which measure the intellectual capital components (3) market value scales and models which focus on the book value of knowledge assets and their market value (4) scales and models of knowledge revenues which are based on calculating returns on assets (ROA). The paper concluded stating that specific issues relating to companies and the nature of the market made it impossible to come up with certain results that can be generalized when making comparison among modern administrative trends or attitudes which defined the intellectual capital as intangible assets. Thus, the researcher urged researchers and parties interested in building up and upgrading companies’ capacities to exert intensive efforts to boost investment in human capital for its key and influential role in accomplishing excellence and enhance the position of these companies.

Цель исследования – изучение влияния профиля поверхности винтового дентального имплантата на остеоинтеграцию.
Материалы и методы исследования. Исследованию подвергли 5 различных систем имплантатов, которые имеют отличные друг от друга способы модификации поверхностей.
Результаты исследования. Изучив степень шероховатости поверхностей выбранных образцов с помощью зондовой микроскопии, оказалось, что обработка с использованием биологически активного керамического порошка обеспечивает максимально развитый микрорельеф поверхности и наиболее высокие показатели шероховатости (Sa до 198,2 нм).
Заключение. В ходе экспериментальных исследований установлено, что дентальные имплантаты с биокерамическим покрытием обеспечивают остеоинтеграцию в короткие сроки от 3 до 4 месяцев с формированием качественного костного матрикса в периимплантатной зоне, что позволяет ускорить ортопедический этап нагрузки дентальных имплантатов.

В статье приведены результаты исследования прочностных характеристик винтовой фиксации ортопедических компонентов к дентальным имплантатам с плоскостным типом соединения.
Цель исследования. Изучить в эксперименте прочностные характеристики винтовой фиксации ортопедических компонентов к дентальным имплантатам с плоскостным типом соединения в условиях циклических нагружений, имитирующих функциональные нагрузки в ротовой полости.
Объекты и методы. Экспериментальное исследование соединения в системе «дентальный имплантат-абатмент» проводили на лабораторной установке в Институте прикладной физики НАН Беларуси. В основу принципа работы установки положено изучение прочностных характеристик испытуемых образцов при циклических механических воздействиях. В экспериментальных условиях оценивали прочностные характеристики винтовой фиксации ортопедических компонентов к 24 дентальным имплантатам из сплава Ti- Al-4V диаметром 3,75 мм и длиной 11,5 мм с плоскостным типом соединения, которые были распределены на 4 группы (n = 6) в зависимости от угла нагружения и силы воздействия.
Результаты исследования и их обсуждение. Установлено, что на новой экспериментальной модели после циклического воздействия дозированной механической нагрузки происходят изменения в системе «ортопедическая конструкция – дентальный имплантат». Причём величина изменений находится в прямой зависимости от места расположения винтового соединения, точки физического воздействия, количества циклов нагружения и угла воздействия нагрузки. Наибольшие изменения происходят со 2-м и 3-м винтовым соединением вследствие близкого расположения к точке приложения силового воздействия.
Заключение. Разработана, изготовлена и апробирована новая экспериментальная модель для оценки прочностных характеристик винтовой фиксации ортопедических компонентов к дентальным имплантатам. Выявлено достоверно значимое снижение показателей глубины соединения и степени зажатия ортопедических винтов после экспериментального нагружения, наиболее значимо они выражены во 2-м и 3-м винтовых соединениях экспериментальной модели. Установлена выраженная корреляционная зависимость (r = 0,73; r = 0,91) при увеличении угла и количества циклов нагружения до 200 000 накопление усталости ортопедических конструкций возрастает в 1,78 раз.

Published: July 2019

Реабилитация стоматологических пациентов с использованием дентальных имплантатов в настоящее время становится все более востребованной и успешной как в нашей стране, так и во всем мире. Наряду с успехами есть также и осложнения, связанные с ошибками на разных этапах имплантологического лечения. Многие осложнения возникают на хирургическом этапе во время установки дентальных имплантатов. Достижение прогнозируемого успеха дентальной имплантации подразумевает использование передающего устройства, которое позволяет реализовать запланированное лечение с наибольшей точностью. Таким устройством является хирургический шаблон. Цель исследования. Провести аналитический обзор литературы, посвященной использованию хирургических шаблонов при дентальной имплантации. Объекты и методы. Для анализа были отобраны научные статьи по проблеме использования хирургических шаблонов при дентальной имплантации за период 1987–2019 гг. Поиск источников выполнялся с помощью библиографических баз данных PubMed, MedLine, Scopus, Республиканской научной медицинской библиотеки, поисковой системы Google. Результаты исследования и их обсуждение. Проведенный детальный анализ отечественной и зарубежной научной литературы показал эффективность метода дентальной имплантации с применением хирургических шаблонов. Заключение. Известные методы лечения с использованием хирургических шаблонов имеют ряд недостатков, которые затрудняют проведение предсказуемой и точной дентальной имплантации у пациентов с концевыми дефектами зубных рядов на верхней и нижней челюсти.
