Authors: TAFINTSEVA S.I. , MOTOZIUK L.N.
Published: March 2023

The article identifies the main characteristics of the child as a client of psychological services, which must be considered by a child psychologist in order to increase the productivity of interaction and effective resolution of the request. Namely, the following leading characteristics are analyzed:unstable state of children’s ego (children’s ego is vulnerable and underdeveloped, which makes the child a difficult client), the leading role of play activities in interaction with the child (action dominates when working with a child, the psychologist must play by himself), taking into account the state of physical and emotional dependence of the child: the role of parents (main task - understanding and / or modifying family dynamics), heterogeneity of mental processes in childhood (counseling process includes child psychologist as a real object to be identified as a facilitator of development), “positive” and “negative” reactions of the child psychologist to the child-client (the child is able to cause unique emotional reactions that need to be understood). Based on these characteristics, the requirements for the personality of a child psychologist are determined.
An Analytical Theory for the Growth from Planetesimals to Planets by Polydisperse Pebble Accretion
Authors: Lyra Wladimir , Johansen Anders , Cañas Manuel H. , Yang 楊 Chao‐Chin 朝欽
Published: March 2023

Pebble accretion is recognized as a significant accelerator of planet formation. Yet only formulae for single-sized (monodisperse) distribution have been derived in the literature. These can lead to significant underestimates for Bondi accretion, for which the best accreted pebble size may not be the one that dominates the mass distribution. We derive in this paper the polydisperse theory of pebble accretion. We consider a power-law distribution in pebble radius, and we find the resulting surface and volume number density distribution functions. We derive also the exact monodisperse analytical pebble accretion rate for which 3D accretion and 2D accretion are limits. In addition, we find analytical solutions to the polydisperse 2D Hill and 3D Bondi limits. We integrate the polydisperse pebble accretion numerically for the MRN distribution, finding a slight decrease (by an exact factor 3/7) in the Hill regime compared to the monodisperse case. In contrast, in the Bondi regime, we find accretion rates 1–2 orders of magnitude higher compared to monodisperse, also extending the onset of pebble accretion to 1–2 orders of magnitude lower in mass. We find megayear timescales, within the disk lifetime, for Bondi accretion on top of planetary seeds of masses 10−6 to 10−4
M
⊕, over a significant range of the parameter space. This mass range overlaps with the high-mass end of the planetesimal initial mass function, and thus pebble accretion is possible directly following formation by streaming instability. This alleviates the need for mutual planetesimal collisions as a major contribution to planetary growth.

The physical properties of transiting exoplanets are connected with the physical properties of their host stars. We present a homogeneous spectroscopic analysis based on the spectra of FGK-type stars observed with the Hydra spectrograph on the WIYN telescope. We derived the effective temperatures, surface gravities, and metallicities, for 81 stars observed by K2 and 33 by Kepler 1. We constructed an Fe i and ii line list that is adequate for the analysis of R ∼ 18,000 spectra covering 6050–6350 Å and adopted the spectroscopic technique based on equivalent-width measurements. The calculations were done in LTE using Kurucz model atmospheres and the qoyllur-quipu (q
2) package. We validated our methodology via an analysis of a benchmark solar twin and solar proxies, which are used as a solar reference. We estimated the effects that including Zeeman-sensitive Fe i lines have on the derived stellar parameters for young and possibly active stars in our sample and found them not to be significant. Stellar masses and radii were derived by combining the stellar parameters with Gaia EDR3 and V magnitudes and isochrones. The measured stellar radii have a 4.2% median internal precision, leading to a median internal uncertainty of 4.4% in the derived planetary radii. With our sample of 83 confirmed planets orbiting K2 host stars, the radius gap near R
planet ∼ 1.9 R
⊕ is detected, in agreement with previous findings. Relations between the planetary radius, orbital period, and metallicity are explored and these also confirm previous findings for Kepler 1 systems.

The CHIME/FRB project has detected hundreds of fast radio bursts (FRBs), providing an unparalleled population to statistically probe the foreground media that they illuminate. One such foreground medium is the ionized halo of the Milky Way (MW). We estimate the total Galactic electron column density from FRB dispersion measures (DMs) as a function of Galactic latitude using four different estimators, including ones that assume spherical symmetry of the ionized MW halo and ones that imply more latitudinal variation in density. Our observation-based constraints of the total Galactic DM contribution for ∣b∣ ≥ 30°, depending on the Galactic latitude and selected model, span 87.8–141 pc cm−3. This constraint implies upper limits on the MW halo DM contribution that range over 52–111 pc cm−3. We discuss the viability of various gas density profiles for the MW halo that have been used to estimate the halo’s contribution to DMs of extragalactic sources. Several models overestimate the DM contribution, especially when assuming higher halo gas masses (∼3.5 × 1012
M
⊙). Some halo models predict a higher MW halo DM contribution than can be supported by our observations unless the effect of feedback is increased within them, highlighting the impact of feedback processes in galaxy formation.

Published: March 2023

In the present work, the performance of monolithic perovskite solar cells (mPSCs) was evaluated with regard to the concentration of methylammonium iodide (MAI) perovskites. The five different perovskite layers were carried out using different ratios of MAI:PbI2, labelled as A0, A1, A2, A3, and A4 accordingly, with corresponding ratios of 1:1, 1.1:1, 1.2:1, 1.3:1, and 1.4:1. In this study mPSCs with a sandwich type structure of glass/FTO/compact (c)-TiO2/mesoporous (mp)-TiO2/mesoporous (mp)-ZrO2/carbon was fabricated for this purpose. The fabricated mPSCs films were fully characterized by X-ray diffraction, Raman spectra and Filed emission scanning electron microscopy (FE-SEM). The photovoltaic characteristics were measured under AM 1.5, It was found that power conversion efficiency (PCE) increased with the increasing the concentration of MAI:PbI2 perovskites, from 1:1 to 1.1:1M. The maximum PCE of 17.68% was achieved mPSCs with MAI:PbI2 (1.1:1) as compared to mPSCs with MAI:PbI2 (1:1) PCE of 15.2%.

Published: March 2023

DME production by methanol dehydration using reactive distillation has a lot of potentials. However, the DME purity and methanol conversion is hard to be controlled and need inferential variable to be controlled. Data driven soft sensors can be utilised to select inferential variables, which can be used to control DME production by using reactive distillation. The data was collected from process simulation using ASPEN and analyzed by using PCA (Principal Component Analysis) and PLSR (Partial Least Squares Regression). The results show that based on the data driven soft sensors method, the DME purity can be controlled by using T4 as an inferential variable and ratio reflux as the manipulated variable. However, the methanol conversion is hard to be controlled because the potential inferential temperature was not significantly affected by reflux ratio and reboiler duty as the candidate manipulated variables.

Published: March 2023

To improve the specific capacitance, power and energy of electrical energy storage devices, in particular hybrid capacitors, various methods of cathode material modification are used. One of the methods of modifying nanostructured materials without applying high temperatures, pressures and long reaction times is ultrasonic treatment. Although the interaction of ultrasound with the structure and surface of electrode materials is well enough studied, there are few works that investigate the optimal duration of ultrasonic treatment and its relationship with the capacitive characteristics of these materials. Therefore, we investigated the efficiency of ultrasonic dispersion of nanocrystalline nickel molybdate hydrate for 15, 60 and 90 minutes. The appearance of two cathodic peaks on cyclic voltammetry patterns was analyzed and the charge / discharge mechanism of the electrode based on nanocrystalline NiMoO4 hydrate was presented. Based on the results of potentiodynamic and galvanostatic studies the specific capacitances of the initial NiMoO4 and the material modified by ultrasound for 15, 60 and 90 minutes were calculated. The proton diffusion coefficients of nickel molybdate hydrate were determined on the basis of the Randles–Sevcik equation. NiMoO4 subjected to ultrasonic dispersion for 60 min as a cathode material in a hybrid electrochemical system was tested.

Authors: Seo Mi-Hae
Published: March 2023

In October 2022, the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) updated the previous consensus report for management of hyperglycemia in type 2 diabetes (T2DM). In January 2023, ADA Standards of Care in Diabetes with pharmacologic approaches to achieve a glycemic target were published to align with the consensus report by ADA and EASD. This recent consensus report and ADA Standards of Care in Diabetes emphasized weight management as an important aspect of the holistic approach to management of T2DM. In addition, it included numerous results of cardiorenal trials involving glucagon-like peptide 1 (GLP-1) receptor agonist and sodium glucose cotransporter 2 (SGLT2) inhibitor in type 2 diabetes. This information was added to address broader recommendations for cardiorenal risk reduction, in particular for organ (heart and kidney)-specific protection. This review summarizes the 2022 ADA-EASD consensus report and 2023 ADA standards of care for diabetes regarding management of hyperglycemia in T2DM.

Published: March 2023

Today, artificial intelligence is a key tool for turning a city into a smart city, and advances in information and communication technology (ICT) have led to the development of smart cities with many different parts. Smart Health is one of these components and is used to improve healthcare by providing services such as disease forecasting, early diagnosis, and others. There are various machine learning algorithms available now that can help with S-Health services, but which is better for disease forecasting? Gedaref State, for example, has some of Sudan's heaviest rains, and malaria and pneumonia are widespread throughout the year. Predicting future trends for these diseases has been a major focus for researchers in order for Gedaref's administration and the state's ministry of health to design effective ways to prevent and control the development of these diseases, as well as to prepare an adequate stock of medicine. As a result, it is necessary to establish a trustworthy and accurate forecasting model to aid Gedaref's government in developing economic and medical strategies for dealing with these diseases, as well as taking action on medical resource allocation. This study uses a time series dataset collected from the state's ministry of health to estimate malaria and pneumonia as common diseases in Gedaref state, Sudan, five months later. To comprehend the overall number of cases of diseases, two forecasting methodologies, namely the ARIMA and Prophet models, are applied to the disease's dataset. The performance of the ARIMA and FB-Prophet forecasting systems in predicting malaria and pneumonia diseases in Gedaref State is compared in this study. The data was collected from the state's ministry of health between January 2017 and December 2021. The results reveal that the ARIMA technique outperforms the FB-Prophet forecasting method in both malaria (RMSE: 182.8, MAE: 141.6, MAPE: 0.0057, and MASE: 0.0537) and pneumonia (RMSE: 1400.3, MAE: 1001.4, MAPE: 0.0513, and MASE: 0.9136).

Authors: Sangeetha S. , Sathappan S.
Published: March 2023

INTRODUCTION: MANETs were a group of nodes which connected each other to establish the network via wireless association to forward packets towards destinations.
OBJECTIVES: Reputation-based Symmetric Key Authentication (RSKA) technique is proposed to improve the security of data communication, which securely transmits data packets within MANET communication. Initially, a reputation counts-based node authentication algorithm is designed in RSKA technique by considering the reputation value of mobile nodes in networks.
METHODS: By using a reputation count-based node authentication algorithm, the RSKA technique performs the node authentication process before initiating route identification and selects cooperative nodes in MANETs for data transmission. Therefore, the RSKA of nodes results in improved security of data communication for enhancing throughput and reducing data loss rate. Besides, the RSKA technique uses symmetric key cryptography for secure data transmission in which a secret key is generated for the data to be transmitted by the corresponding mobile node along the route path of the source-destination pair. The destination node having the secret key can only decrypt the cypher text.
RESULTS: Thus, the RSKA technique improves the data confidentiality rate as well as minimizes the time to protect the data transmission in an efficient way. RSKA was calculated by various parameters, namely data loss rate, throughput and time to protect data delivery as well as data confidentiality rate. CONCLUSION: The simulation result of RSKA improves the data confidentiality rate for achieving secured data transmission as well as minimizes time to protect data delivery within MANETs compared with conventional methods.

For centuries, bread has been the world population's basic alimentary item. It is a bakery product made from the dough that has undergone the process of kneading, shaping, fermentation and baking. The purpose of this work is to determine the nutritional values and the microbiological quality of bread made from different types of flour. Energy value of bread was calculated based on the content of carbohydrates, proteins and fats. Microbiological quality control included bacteria that cause food spoilage, namely Salmonella spp., Listeria monocytogenes, Enteriobacteriaceae, Bacillus cereus, as well as molds and yeasts. The results of examining the energy value parameters, which are presented in our work, are in accordance with the Regulations concerning methods of physical and chemical analysis for testing quality control of grains, mill and bakery products, pasta and quickfrozen dough products. All tested microbiological parameters of white and wholemeal bread, as well as buckwheat and rye flour bread, were within the acceptable values, while corn flour bread had a slightly higher content of yeasts and molds than the prescribed standard.

Water is an indispensable part of beer and brewing practice, and therefore it is not even possible to imagine a process in which water quality is neglected. For the purposes of this experiment, several different watersamples were collected from available springs. The basis of the experiment was the colored reaction of iodine on starch, which would prove the hydrolysis of starch granules from grains. This leads to the conclusion that the mineral composition, which affects the hardness of the water, does not have a decisive influence on the work of amylolytic enzymes, at least not to the extent that would significantly affect the production process.

Meningkatnya pertumbuhan jumlah penduduk serta keinginan untuk memiliki kendaraan pribadi membawa permasalahan lalu lintas berupa kemacetan di Kota Jakarta. Solusi kemacetan yang digemari oleh mayoritas pekerja di Kota Jakarta yaitu memanfaatkan transportasi publik. Salah satu moda transportasi publik yang dominan adalah kereta api. Namun, hal ini lantas membuat permasalahan baru di tempat pengadaan moda kereta api yaitu stasiun. Lahan yang terbatas dan tingginya pengguna kereta api menyebabkan kapasitas ruang parkir yang ada tidak dapat menampung seluruh kebutuhan parkir, sehingga mengharuskan pengunjung untuk memarkirkan kendaraannya di luar stasiun Palmerah. Penelitian ini akan membahas bagaimana karakteristik parkir di stasiun Palmerah, lalu apakah kebutuhan parkir sudah terpenuhi, dan bagaimana redesign parkir agar lahan yang ada menjadi lebih efisien. Dari penelitian ini diketahui bahwa indeks parkir di stasiun Palmerah mencapai angka 220%. Hal ini mengartikan bahwa fasilitas parkir di stasiun Palmerah bermasalah. Adapun jumlah kebutuhan ruang parkir yang didapatkan setelah penelitian berbanding jauh dengan lahan yang ada. Lahan yang ada hanya menampung 70 SRP sedangkan kebutuhan parkir adaah 143 SRP. Me-redesign fasilitas ruang parkir menjadi bangunan bertingkat menggunakan sistem APS adalah solusi yang baik untuk mengatasi permasalahan ini. Lahan parkir akan di-redesign menjadi bangunan bertingkat empat dengan kapasitas maksimum 152 SRP dari total kebutuhan 143 SRP. Dengan me-redesign lahan parkir dengan bangunan bertingkat bersistem APS, stasiun Palmerah akan mampu menampung kendaraan dengan jumlah melebihi akumulasi dan volume parkir maksimum.

Sistem drainase adalah serangkaian sarana dan prasarana yang digunakan untuk mengurangi atau membuang kelebihan air pada suatu wilayah atau lahan, sehingga lahan dapat difungsikan secara optimal. Tujuan penelitian ini adalah untuk mengetahui debit rencana dan dimensi yang sesuai dengan kala ulang 2, 5, dan 10 tahun. Lokasi penelitian ini adalah saluran drainase di Jalan Pramuka Kecamatan Rajabasa Kota Bandar Lampung. Penelitian ini dilakukan dengan dua jenis analisis, yaitu analisis hidrologi dan analisis hidraulika. Analisis hidraulika menggunakan program Storm Water Management Model (SWMM) untuk mempermudah proses evaluasi, selanjutnya menghitung debit rencana saluran dan menentukan dimensi saluran yang sesuai. Hasil perhitungan parameter statistik diperoleh distribusi Log Pearson III dan diperoleh debit rencana untuk kala ulang 2 tahun sebesar 13,5487 m3/detik, kala ulang 5 tahun sebesar 18,4453 m3/detik, dan kala ulang 10 tahun sebesar 21,8985 m3/detik. Berdasarkan hasil evaluasi dimensi saluran kondisi eksisting, saluran drainase di Jalan Pramuka perlu didesain ulang terutama pada zona 5 sampai zona 10. Disarankan dengan dimensi rata-rata pada kala ulang 2 tahun yaitu b = 0,75 m x h = 1,15 m, kala ulang 5 tahun yaitu b = 0,85 m x h = 1 m, dan kala ulang 10 tahun yaitu b = 0,85 m x h = 1,35 m sehingga saluran drainase mampu menampung debit banjir.

Dalam pengurusan cuti ASN, instansi yang yang bertanggung jawab dalam mengurus urusan kepegawaian lingkungan Pemerintahan Kabupaten Toraja Utara yakni Badan Kepegawaian, Pendidikan, dan Pelatihan (BKPP) Kabupaten Toraja Utara. Masalah yang terjadi pada BKPP Kabupaten Toraja Utara mengenai masalah cuti pegawai yang akan diajukan ASN. Terkadang masih ada ASN yang belum memahami aturan cuti sehingga pada saat ASN datang ke kantor BKPP membawa berkas permohonan cutinya, pengajuannya tidak dapat diproses lebih lanjut disebabkan karena permohonan cutinya yang tidak sesuai dengan aturan cuti yang berlaku. Ketika ASN ingin mengajukan cuti tahunan, BKPP Bidang Diklat harus mencari satu persatu arsip cuti pegawai dalam bentuk buku agenda untuk mengetahui sisa cuti pegawai tersebut, kemudian BKPP membuatkan surat pengantar pengajuan cuti ASN, yang mana itu membutuhkan waktu yang lama dan cukup ribet sehingga pengurusan pengajuan cuti pegawai menjadi lebih lama. Oleh karena itu, dibutuhkan pembuatan suatu sistem informasi cuti ASN sehingga pemrosesan pemberian cuti ASN lebih cepat dan tepat dilakukan. Metode yang digunakan dalam pengembangan sistem ini adalah metode waterfall yang memiliki tahapan mulai dari analisis, perancangan, implementasi dan pengujian. Hasil pengujian blackbox yang telah dilakukan semuanya berhasil atau tidak adanya kesalahan (error) dan hasil pengujian implementasi sistem menggunakan User Acceptance Test (UAT) sudah sangat baik digunakan oleh ASN dalam mengajukan cuti dengan memperoleh nilai persentase 87,99%.

Tanaman holtikultura yang awalnya dikenal sebagai tanaman perkebunan rakyat mulai berkembang pesat dengan perkembangan teknologi saat ini. Metode budidaya dengan hidroponik mulai digemari karena dianggap lebih efisien pada penggunaan lahan dan perawatan. Pemberian nutrisi pada tanaman sayuran hidroponik merupakan kewajiban yang harus dilakukan secara berkala dengan cara mengukur nutrisi yang ada pada larutan hidroponik secara konvensional. Hal tersebut dapat ditunjang dengan penggunaan teknologi mikrokontroller. Pada penelitian ini dibuat rancang bangun alat kontrol kadar nutrisi dalam air pada sistem hidroponik dengan Total Disollved Solid (TDS)”. Pengujian dilakukan dengan mempompa nutrisi terlarut AB mix dan air baku kedalam wadah penampung sampai sensor TDS meter dan sensor HY-SRF05 mendeteksi nilai kondisi tertentu. Selanjutnya disirkulasikan ke talang pipa tanam yang menjadi kebutuhan tanaman sawi. Hasil pengujian tersebut kemudian dibandingkan yaitu pemberian larutan nutrisi dengan alat TDS & EC antara sensor TDS meter selisih paling rendah adalah 0,05 atau sebesar 4,9 % sedangkan yang paling tinggi adalah 0,36 atau sebesar 36,3 %.

Authors: Tyler John , Dr. Panayotis Thanos
Published: March 2023

The major benefits of resistance training include four primary areas: cardiovascular, musculoskeletal, neuropsychological, and metabolic. Resistance exercise improves overall cardiovascular health while significantly reducing the risk of associated diseases. Cardiovascular health is specifically enhanced through the lowering of blood pressure as well as improved lipid and inflammatory profiles. Resistance training enhances musculoskeletal health through increases in bone mineral density, tendon and ligament thickness, muscle hypertrophy, and increases in balance and flexibility. Additionally, strength training provides an effective treatment option for osteoporosis, osteopenia, sarcopenia, arthritis, and low-back pain. Neuropsychologically, resistance exercise reduces anxiety, stress, and depression, while increasing cognitive function in healthy and diseased individuals. Obesity and weight management comprise the primary metabolic focus. Resistance training effectively manages weight and body fat by increasing fat-free mass, resting metabolic rate, and caloric expenditure. Overall, resistance exercise presents an effective treatment option for disease prevention and intervention by improving health and wellness.
