Tools for planning large-scale measurement surveys for the assessment of indoor environmental pollutants: the case of radon
Authors: Salvi Francesco
Published: December 2023

Risks from indoor pollutants require the implementation of effective policies to prevent and reduce exposure. To take decisions and actions, competent authorities need relevant information. In the case of indoor radon exposure, surveys are carried out by installing detectors in buildings (homes, workplaces) that measure radon concentration in rooms. Conducting national or large-scale surveys in buildings requires addressing both technical complexities of implementation and economic costs. In order to support the implementation of large-scale radon surveys, procedure and tools are described for defining the sample size of buildings to be measured according to available resources, for planning the sampling of buildings in relation to the specific objectives of the survey, and for obtaining a tool for management and control of sample recruitment and installation of radon detectors in buildings, reducing sources of bias. A particular application is shown for the case of the EU radon regulation.

Authors: Оборжицький Валерій Іванович , Сторож Володимир Георгійович , Фабіровський Сергій Євгенович
Published: December 2023

У статті запропонована схема і метод розрахунку двосмугового мікросмужкового балуна, який у двох смугах частот поряд з рівноамплітудним і протифазним розподілом сигналу між виходами забезпечує трансформацію комплексних опорів навантаження, різних у цих смугах, у дійсне значення вхідного опору джерела. При цьому досягається узгодження входу і виходів пристрою з високим рівнем розв’язки останніх. Запропонована структура складається з каскадного з’єднання чотирьох відрізків зв’язаних ліній, двох реактивних елементів, що реалізуються шлейфами, і ланки розв’язки виходів, для реалізації якої приведено три варіанти схем. Наявність у схемі елементів, параметри яких можна задавати, забезпечує гнучкість процесу проєктування без обмежень на значення опорів навантаження. Крім того, в процесі розрахунку враховується різниця фазових швидкостей мод мікросмужкових зв’язаних ліній. Для перевірки властивостей запропонованої схеми та методу її проєктування виготовлено та експериментально досліджено мікросмужковий балун на дві робочі смуги частот з середніми значеннями 1,4 ГГц і 2,8 ГГц при різних комплексних опорах навантаження. Результати вимірювань добре узгоджені з результатами електромагнітного моделювання і показують, що в обох смугах розбаланс амплітуд і фаз на виходах балуна не перевищує 1 дБ і 10 градусів відповідно, підтверджуючи доцільність використання запропонованої схеми та методу її проєктування.

Підвищення ефективності максимальної потужності сигналів NOMA покоління 5G і вище з використанням SLM алгоритму
Authors: Гоур Н. , Гаур Н. , Шарма Х.
Published: December 2023

В роботі представлено новий підхід для послаблення шкідливих впливів великого значення відношення пікового рівня потужності до середнього PAPR (Peak-to-Average Power Ratio), притаманних сигналам неортогональної системи множинного доступу NOMA (Non-Orthogonal Multiple Access), при застосуванні техніки вибіркового відображення SLM (Selective Mapping). NOMA — добре відома схема множинного доступу в сучасних системах безпроводового зв’язку, яка сприяє одночасній передачі сигналів багатьох користувачів за допомогою одного частотно-часового ресурсу. Однак система NOMA чутлива до підвищених рівнів PAPR, що викликає погіршення ккд та міжсимвольні перешкоди. Пропонований метод використовує SLM для подолання піків PAPR в сигналах NOMA. Шляхом формування набору різноманітних послідовностей фаз, SLM створю альтернативні варіанти оригінального сигналу NOMA. Тоді фазова послідовність, яка призводить до найнижчого значення PAPR, вибирається для передачі. Ця динамічна адаптація суттєво зменшує піки переданого сигналу і таким чином підвищує ккд, мінімізує спотворення, та зменшу ризик нелінійного підсилення. Проведено моделювання для оцінки ккд процедури, що розробляється. Результати показали значне зниження PAPR в сигналах NOMA у порівнянні з традиційними методами передачі. Крім того, цей метод зберігає якість сигналу та зменшує рівень бітових помилок BER (bit error rate), покращу спектральну густину потужності PSD (power spectral density) та підвищу загальну надійність структури радіомовлення. Ця стаття приводить до висновку про реалістичність інтегрування SLM в існуючі системи на основі NOMA, пропонуючи перспективний шлях для оптимізації ефективності сучасних радіомереж.

Authors: Lailiah Novianti , Nursalam  , Indarwati Retno
Published: December 2023

People living with HIV (PLWH) experience higher psychological distress than the general population. Interventions to improve PLWH’s psychological condition need to be adjusted to the their age as each age group’s cognitive abilities are different. This systematic review aims to demonstrate age group-based interventions to improve psychological outcomes in PLWH. A search on articles (2014-2022) focused on experimental studies was conducted on Scopus, SAGE Journal, Science Direct, and PubMed. The searched articles tested interventions to improve psychological outcomes in PLWH and were published in English. The Joanna Briggs Institute (JBI) guidelines were used to assess their eligibility, and PRISMA diagram was used to compile the results of the search. Fifteen studies that matched the inclusion criteria were obtained, and they had experimental study designs. Several types of interventions were identified from the obtained literature. These interventions were designed according to their research subjects, and had been proven to have a significant effect on improving psychosocial conditions and quality of life in PLWH. Further research about age group-based interventions to improve psychological outcomes in PLWH is necessarily suggested. Future research is expected to be able to design interventions that focus on building resilience in individuals. The resilience is to make individuals manage their stress optimally. This may improve not only their psychosocial status but also their adherence to treatment and quality of life.

One of the organic farming goals is improving soil properties to support sustainable rice production. This study investigated the soil properties and rice yields under temporal variation of organic rice fields. Soil sampling was conducted in organic rice fields with three temporal variations, namely 0, 4, 7, and 10 years in a tropical monsoon region in Central Java, Indonesia. Variables observed included soil organic carbon, soil carbon stock, soil microbes population, dissolved organic carbon, soil liquid limit, soil sticky limit, soil plasticity limit, soil color changing limit, soil friability, soil porosity, soil total nitrogen, soil total phosphorus, soil available sulfur, exchangeable calcium, cation exchange capacity, total potassium, bulk density, base saturation, exchangeable sodium, exchangeable potassium, and rice yield.  This study confirms that soil organic carbon increased by 51.63% within 10 years (from 1.84% to 2.79%). Organic farming also improved all the physical, chemical, and biological soil properties, by the increase of soil organic carbon. However, soil organic carbon is mostly determined by soil cation exchange capacity, soil total phosphorus, and soil porosity. The mechanism of rice yield increase in organic rice farming is not affected by soil organic carbon directly but through the synergic increase in soil total nitrogen. The 1% increase of soil organic carbon increases 0.065% of soil total nitrogen hence rice yield increases by 1.66 tons ha-1. This study supports sustainable agriculture by providing evidence of improved soil properties under organic farming.
The role of red mud and cow manure for sustainable post-gold mining land rehabilitation
Authors: Suswati Denah
Published: December 2023

The detrimental ecological impact of unauthorized gold mining in Indonesia is significantly profound, notably apparent in the nutrient-deficient, sandy soils with low pH resulting from the process. These conditions contribute to considerable land productivity decline, especially in West Kalimantan. In response to this challenge, the current study proposes an inventive approach for soil reclamation using red mud residue, derived from bauxite ore extraction, and cow manure as restorative elements. This research delves into a novel soil restoration technique that employs red mud waste (a residual from ore refinement) in conjunction with cow manure as ameliorative agents. A distinct amalgamation of 0.2 kg of red mud and 3 kg of cow manure (T2R3) showcased superior results. The incorporation of this blend resulted in a significant increase in soil pH by 0.93 units, an increase in macronutrient content ranging from 82.84%-503.07%, and plant growth (plant height and stem diameter) increased between 32.85%-54.31% in the treatment with 0.2 kg of red mud and 3 kg of cow manure (T2R3) compared to the lower treatment of 0.1 kg of red mud and 1 kg of cow manure (T1R1). These changes were evident, indicating improved soil fertility and the potential for increased crop yield

Authors: Choukri Majda , Naimi Mustapha , Chikhaoui Mohamed
Published: December 2023

This study examined the worsening severity of global droughts caused by climate change. However, the multiple definitions and varied range of drought indices pose challenges in effectively monitoring and assessing the prevalence and severity of droughts. This study aims to give a comprehensive overview of the various drought definitions found in the literature and how they have evolved based on their applications. Specifically, the focus was to shed light on the dynamic nature of drought characterization and offer insights into the factors that shaped its conceptualization over time. Within this context, this study explored three primary categories of drought indices: climatic, remote sensing, and composite. Each category was discussed in relation to its utility in specific fields, such as meteorological, agricultural, and hydrological drought assessments, along with an analysis of their strengths and limitations. Furthermore, this study presents modified meteorological drought indices that have been adapted to better monitor agricultural droughts. Additionally, the authors used geographic information systems to create a map showing the distribution of drought-related publications globally over the past decade. The findings showed that countries with arid and semi-arid climates are more actively involved in drought research, highlighting their particular interest and concern regarding the subject matter. The implications of this study emphasize the urgent need for immediate and coordinated efforts to address the escalating issue of droughts caused by climate change. By improving monitoring and assessment methods and focusing on tailored strategies in vulnerable regions, it is possible to mitigate the far-reaching consequences of drought and to build more resilient communities and ecosystems.

The article considers the process of wear of the friction surfaces of disc brakes, taking into account their designparameters, the coefficient of wear resistance of materials, the initial braking speed of the car, the amount of mileage andits braking distance during this period, which are used to estimate the resource of braking mechanisms.For this, a systematic approach was used, a rational combination of experimental research and analysis of knowntheoretical scientific results of I.V. Kragelsky on the theory of friction and wear.It is known that in order to estimate the resource of braking mechanisms of motor vehicles, it is important to establishthe amount of permissible wear of friction surfaces that form frictional contact.The authors established the regularity of changes in the wear of the friction surfaces of disc brake mechanismsdepending on the friction radius, the kinematic rolling radius of the wheel, the amount of drive pressure and the brakingdistance of the car.It is important to assess the service life of brake mechanisms of passenger cars in operation is to establish thepermissible relative wear of individual parts and couplings of brake mechanisms. Since the most responsible part of thecar's braking system, which is the brake mechanism, works in different conditions of wear, then establishing the relativewear of the coupled parts that create friction, depending on the change in its geometric parameters and operating modesduring operation, is an urgent task.A predictive assessment of the resource of brake mechanisms of the front and rear axles of passenger cars is provided,which is proposed to be carried out based on the indicator of the relative wear of the friction surfaces. It is shown on theexample of Chevrolet Aveo passenger cars that the relative wear of the brakes of the front axle is maximum and variesbetween 22.5-26.1%, while the relative wear of the brakes of the rear axle is 21.0-22.5%. The resource of the brake discis 4.44 times greater than the resource of the friction pad, while this indicator is 4.76 for the rear axle.

Parents have the right to raise children. It was found that several parents applied authoritarian parenting to develop children's social intelligence. This study aims to determine whether the application of authoritarian parenting by parents to their children can develop social intelligence. The method used is qualitative. The research was conducted in April-May, at SMP Negeri 92 Jakarta to be precise, with the research subjects consisting of six key informants and four key informants. From this study, it was found that the authoritarian parenting style adopted by parents came from internal factors (parental personality, parenting beliefs, parents' age, and parents' gender) and external factors (parents' education, socioeconomic status, and environment). Not all children who grow from authoritarian parenting have good social intelligence. Because two out of four students actually withdraw from the environment that requires them to interact. For parents who believe that applying authoritarian parenting can develop children's social intelligence, they need to pay attention to several things, such as increasing knowledge by participating in parenting training, providing fair care for each child, and living in a good social environment. In addition, the application of authoritarian parenting by parents with the aim of developing children's social intelligence should be reconsidered because there are several things that need attention, such as the child's mental condition.

Authors: NAS Şahin , MİÇOOĞULLARI Seyit Ali , MOALLA Maya
Published: December 2023

With globalization, the international fragmentation of production (IFP) splits the production process of final goods and services into several stages undertaken in different countries integrated into global production networks. BRICS + T countries have rapidly participated in the (IFP) process especially after 2000s. The main purpose of this paper is to analyze the nexus between BRICS+T countries’ participation in the global production networks and their economic development. The vertical specialization rate, as an indicator of this participation, had been calculated utilizing OECD Input-Output Tables. Subsequently, the development index was calculated utilizing economic-technological and cultural-institutional indicators published by World Bank. The vertical specialization’s impact on development was estimated utilizing the CS-ARDL estimator. The results revealed that while the vertical specialization has a statistically significant positive impact on development in the short term, a positive but not statistically significant impact was recorded in the long term. Konya (2006) causality test was performed to examine the causal relationship among the selected variables. The results revealed a one-way causality running from development to vertical specialization in China and Turkey and a one-way causality running from vertical specialization to development in Brazil. No causality relationship could be detected in other countries included in the analysis.
