A Fuzzy Analytic Hierarchical Method to Reduce Imprecision and Uncertainty in Drilling Operation’s Factor Selection Process for Unidirectional Carbon Fibre Reinforced Plastic Composite Plates
Authors: Odusoro Salome Ifeoluwa , Oke Sunday Ayoola
Published: March 2022

Parametric selection in machining processes is recently understood as a route to reducing waste generation in drilling activities and achieving a robust resource distribution in drilling activities. However, the selection methods dominant in the literature lack competence in reducing uncertainties and imprecision associated with the drilling process. The purpose of this research is to reduce the uncertainty and imprecision in previously analyzed data that used the analytic hierarchy process (AHP) method. This paper adjusts the uncertainty and imprecision by introducing a geometric mean-based fuzzy analytic hierarchy process. The selection method influences the drilling expert's preferences by imposing the fuzzy theory in a triangular member function that converts the crisp numerical values into fuzzy members and adequately suppresses the imprecision and uncertainty in the elements. The thrust force was positioned first in ranking with a FAHP method's weight of 0.415, which matched the literature value of 0.413 for the AHP method. It was found that the use of the FAHP method has corrected the imprecision and uncertainty introduced by the AHP method. It was found that the thrust force and torque were overestimated by or 0.48% and 3.95%, respectively and was accordingly corrected. Besides, no errors were found with the measurement of eccentricity response. Furthermore, the entry delamination, exit delamination and surface roughness were underestimated by -8.11%, -3.33% and -6.96%, respectively, and therefore corrected by the FAHP method. The usefulness of this effort is to enhance cost-effective decisions and the effectiveness in the distribution of scarce drilling resources.
Error Performance Analysis of Wireless Video Communication Systems Employing Multi-level MPSK Modulation and MIMO Technologies
Authors: Hosany Mussawir Ahmad
Published: March 2022

Real-time communications of high definition video with the available limited channel bandwidth is a fundamental requirement for modern mobile and wireless networks such as Wi-Fi, WiMax, 3G, LTE and the emerging 5G. To fulfill this requirement, H.264/AVC and High Efficiency Video Coding (HEVC) or H.265 standards have been implemented to achieve high error performance over wireless channels and large compression efficiency thereby optimizing channel bandwidth. The problem of establishing and maintaining reliable communication paths among mobile users employing multiclass bitstreams to achieve high spatial diversity and coding gains is a big challenge for researchers. In practice, multimedia standards employ data partitioning where different levels of importance are assigned to the multimedia content.
The problem of transmission of coded HEVC data over wireless channels employing MIMO technologies to maximize high spatial diversity and coding gains has not been explicitly explored in existing research works. Moreover, to meet the demand of 5G networks in providing ultra-reliable low latency communications it is required to study fully the performance of multimedia data over wireless channels. To this end we propose, in this paper, to study and analyze the performance of coded MIMO systems employing a triple-class bitstreams source namely a high priority, medium priority and low priority class. The objective of our study is to promote Unequal Error Protection (UEP) as well as spatial diversity of the coded bitstreams without sacrificing the channel bandwidth and increasing the computational complexity. Space-Time Block Codes with Orthogonal properties and Hierarchical or Multi-level 8PSK modulation are considered in our analysis and the adopted approach will be shown, through numerical evaluation and simulations, that excellent UEP capabilities as well as high spatial diversity gains can be achieved.
New Bit Error Rate (BER) expressions in closed form are derived for independent and identically distributed Rayleigh channel in the presence of Additive White Gaussian Noise (AWGN). Single and multiple fading channel reception systems with Maximum Ratio Combining (MRC) are considered. The simulations of our proposed UEP transmission model are designed and implemented in Matlab Simulink® R2017. It is shown that the most important priority data gives a coding gain of around 11 dB over the less important one at a BER of 10--6 for an 8-diversity order Orthogonal Space-Time Block Code (OSTBC) employing Hierarchical 8PSK modulation. This work can be extended to evaluate the error probability of multiuser coded systems for 4G and 5G networks.
Static and Buckling Analysis of a Three-Dimensional (3-D) Rectangular Thick Plates Using Exact Polynomial Displacement Function
Authors: Onyeka F. C. , Okeke T. E. , Nwa-David C. D.
Published: March 2022

This paper is devoted to study the buckling response of axially compressed rectangular thick plate based on the exact polynomial potential functional. The governing and equilibrium equation of an isotropic plate was derived based on the three-dimensional (3-D) static theory of elasticity, to get the relations between the rotations and deflection. These equations are solved in the form of polynomial analytically to obtain the exact displacements and stresses that are induced due to uniaxial compressive load action on the plate. By incorporating deflection and rotation function into the fundamental equation and minimized with respect to deflection coefficient, a new expression of the determination of the critical buckling load was established. This expression was applied to solve the buckling problem of a clamped thick rectangular plate which was simply supported at the first and freely supported at the third edge (SCFC). A graphic representation of results showed that, as the aspect ratio of the plate increases, the value of critical buckling load decreases while as critical buckling load increases as the length to breadth ratio increases. This implies that an increase in plate width increases the chance of failure in a plate structure. This theory obviates the numerical approximations in the thickness direction thereby guaranteeing accuracy in the solution of the displacement along the direction of thickness axis of the plate, hence, a significant lessening of the cost of computation.

Authors: Darmayasa I. Made , Friska  , Anggakusuma
Published: March 2022

Background: Congenital disorders are a global problem with a greater incidence in developing countries. Knowing the presence of congenital abnormalities in pregnancy is a bad experience that is very unpleasant. In fact, it is Bed Breaking News which is very difficult for a pregnant woman to accept. A special approach is needed to inform patients and their families. Especially if the pregnancy termination will be carried out.
Methods: A case report of a 26-year-old second pregnant woman, with multiple congenital fetal anomaly
Results and Discussion: The mental stress experienced before and after the termination of pregnancy proved to be a serious problem. Knowing that there are congenital and multiple abnormalities in the baby they are carrying, pregnant women experience shock, sadness, and do not want to accept it, let alone termination of pregnancy. The patient even had time to seek a second opinion to reassure him. After the termination of pregnancy, the patient has just entered a recovery period and is gradually improving.
Conclusion: Although it takes time, the patient is ready to accept the results of the examination and agrees to terminate the pregnancy.

Published: March 2022

The generation of organic waste is one of the biggest problems in developing countries like Indonesia. Examples of organic waste that can be obtained, such as leaves, include banana leaves and coconut leaves. One way to process waste that can generally be done is by composting. In the composting process, a bioactivator such as EM4 is needed to accelerate the reaction process in the waste. This study aimed to determine the effectiveness of EM4 bioactivator in the degradation process of banana leaf and coconut leaf waste. Measurement of processing quality is measured in-situ with parameters of temperature, pH, and humidity. The waste temperature increased above 32oC for the addition of EM4 bioactivator, while without the addition of bioactivator it only increased to 31oC. pH tended to be in normal conditions and was in an acidic state on day 12. Humidity decreased from the beginning of the waste process to the end of the process. The final result of composting quality has met the criteria of SNI 19-7030-2004. There was also a decrease in the C/N content during the process, adjusting to soil conditions. The decrease in the value of C/N on the addition of bioactivator also influences the composting process.

Published: March 2022

Subject. The article considers global aerospace and defense companies operating in conditions of COVID-19 pandemic.
Objectives. The focus is on systematization of experience in combating the pandemic and analysis of changes in the global aviation market that need to be reflected in the development strategy of the Russian aviation industry.
Methods. The research methodology rests on the comparative analysis.
Results. The analysis showed that COVID-19 pandemic had practically no impact on the military segment of the aircraft industry. Restrictions on international transportation changed the ratio between international and regional air transportation in favor of the latter. At present, narrow-body jet aircraft with a capacity of 120–150 seats, regional aircraft of medium and large capacity, and general purpose aviation are the most popular. The business segment faces increased competition. The revenues of commercial aircraft manufacturers show a dramatic decline.
Conclusions. Diversification of defense and aerospace companies enables to overcome the crises caused by the COVID-19 pandemic. However, a sharp drop in demand for air transportation entailed restructuring in the global aviation market.

ANALISA KETERSEDIAAN KETAHANAN PANGAN PROVINSI KALIMANTAN TIMUR MENYAMBUT RENCANA IBU KOTA NEGARA BARU
Authors: Rachim Abdul , Habibi Muhammad
Published: March 2022

Pada hari Selasa 24 Agustus 2021 dalam pemberitaan kantor berita Antara, saat meninjau sodetan akses jalan menuju Ibu Kota Negara di Jalan tol Balikpapan-Samarinda KM 14, Presiden Republik Indonesia Bapak Joko Widodo menegaskan bahwa pembangunan IKN yang baru dio Provinsi Kalimantan Timur tetap diteruskan. Artinya bahwa Kalimantan Timur harus terus bersiap sedia, termasuk kedatangan sekitar 1,5 juta pejabat dan pegawai pemerintah pusat bersama keluarga, yang harus mendapat dukungan pasokan pangan. Pangan dalam kehidupan sehari-hari merupakan kebutuhan pokok manusia. Tanpa pemenuhan pangan, manusia tentu tidak dapat tumbuh dan berkembang dengan baik.

Adapun tujuan penelitian adalah mengetahui Ketersediaan Ketahanan Pangan Provinsi Kalimantan Timur menyambut Rencana Ibu Kota Negara Baru, dan mengetahui berbagai aspek yang berkenaan dengan Ketersediaan Ketahanan Pangan Provinsi Kalimantan Timur Menyambut Rencana Ibu Kota Negara Baru.Penelitian ini menggunakan metode penelitian kualitatif dengan sifat deskriptif, dengan analisis data menggunakan Analisis SWOT.

Hasil penelitian menunjukkan bahwa kondisi ketahanan pangan di Kalimantan Timur saat ini masih memerlukan perhatian yang lebih fokus, agar kerentanan pangan dapat dihindari. Mengingat dari sektor pertanian, peternakan, dan perikanan hanya komoditas ternak Domba dan Babi yang swasembada. Komoditas seperti beras, sayuran, buah-buahan, daging, ayam, itik bahkan telur masih membutuhkan pasokan dari wilayah tetangga. Hasil analisis SWOT menunjukkan bahwa yang paling rentan adalah masih adanya alih fungsi lahan pertanian ke sektor perkebunan sawit, batu bara, hingga properti perumahan. Sedangkan potensi pangan pada tingkat Kabupaten/Kota belum terpetakan dengan baik sehingga kebijakan yang ditetapkan belum dapat mengungkit potensi pangan yang dimiliki. Kebijakan dan program yang telah ditetapkan dan diaplikasikan oleh Pemerintah Provinsi dan Kabupaten/Kota masih perlu dikembangkan berbasis pada potensi produksi dan pengolahan hilirisasi produksi. Perlu kebijakan strategis yang berbasis pada kepemudaan dalam rangka pencapaian kondisi ketahanan pangan yang modern berbasis teknologi modern.

Body Composition Assessment in Masters Level Swimmers
Authors: Larson Megan , Morgan Amy , Kiss Jessica , Ludy Mary-Jon
Published: March 2022

Body composition of collegiate swimmers has been extensively studied; however, there are limited reports of body composition among Masters swimmers. This study compared the accuracy of air displacement plethysmography (ADP) and bioelectrical impedance (BIA) to the gold standard method of underwater weighing (UWW) in Masters level swimmers. The relationship between percent body fat (%BF) and body mass index (BMI) was also assessed. Recruitment (n = 6 females, 11 males) occurred at two Masters swim clubs. Pearson correlation coefficients revealed no significant differences between ADP, BIA, and UWW (p > 0.05). For both female and male Masters swimmers, the mean %BF was in the healthy range (30.4 ± 11.7% female, 21.3 ± 8.0% male); however, BMI was in the overweight range (27.0 ± 7.2 kg/m2 female, 26.4 ± 4.8 kg/m2 male). These findings suggest that while ADP, BIA, and UWW were comparable methods for assessing %BF in Masters swimmers, BMI did not adequately represent body composition and health risk for Masters swimmers.
Examining Youth Conceptualizations of Water Safety Behaviors among Participants in a Learn-to-Swim Program
Authors: Anderson Austin , Anderson Kristina , Ramos William , Beale-Tawfeeq Angela
Published: March 2022

Drowning represents a leading cause of unintentional deaths among children. Concomitantly, while formal swim instruction often incorporates water safety practices, the efficacy of these messages remains largely unexplored. This qualitative-based study sought to evaluate how youth apply learned water safety concepts when posed with a hypothetical aquatic scenario. Semi-structured interviews, augmented by use of a visual illustration prompt, were conducted with 29 participants of a youth Learn-to-Swim (LTS) program. Interviews assessed participants’ expressed water safety behaviors and were coded based on emergent themes. Findings indicated that most participants were able to identify a “struggling” swimmer in the dramatized illustration. When questioned regarding their hypothetical behavioral response to that swimmer in trouble, participants ultimately yielded appropriate behaviors (e.g., extending one’s reach) with prompting, revealing they would eventually enter the water. Additionally, participants also frequently mis-conceptualized or reported hesitancy in other behaviors; for instance, “calling” for help was sometimes misinterpreted to exclude contacting 911. Results also indicated that other sources, such as television, were important sources of water safety knowledge among participants and that relationships with social agents played a role in water safety messaging. Given these results, LTS programs and public health agencies should work to further improve the prioritization, practice, and communication of water safety behaviors.

Published: March 2022

Drowning is one of the leading causes of death worldwide and lifeguards’ action can be regarded as a significant contribution to change that reality. In this regard, the purpose of this systematic review was to identify factors associated with lifeguards’ performance. After extensive research on PsycArticles, PsicBooks, PsycInfo, SportDiscus, Web of Science, PubMed, Scopus and SportDiscus databases, containing the keywords “lifeguard” AND “performance”, “lifeguard” AND “skills” and “lifeguard” AND “drowning”, we obtained 429 research articles. After eliminating duplicates, excluding those that had no relevance to the study, and screening against set criteria, a total of five articles were fully reviewed. Four quantitative studies and one qualitative study were included in the present review. An analysis of the data was carried out and the findings indicated that there are determining factors for the successful performance of the lifeguard’s activity. Results indicate that factors related to the physical, technical, and psychological components are essential for an improved lifeguard’s performance. The analysis of the data also highlights the lack of studies related to behavioural competencies.

Published: March 2022

Improved eating behaviors and daily participation in physical activity such as swimming might abate the likelihood of African American youth becoming obese. Yet many African American youth neither consume the recommended daily servings of nutritious foods nor know how to swim. The purpose of this study was to investigate the impact of a culturally tailored multicomponent summer intervention to reduce obesity and unintentional drownings among underserved African American youth. Children (n = 145) participated in a three-hour, community-based intervention for four weeks. Measures of children’s attitudes perceived behavioral control, and subjective norms toward swimming, nutrition, and physical fitness were taken at baseline and 4 weeks later (n = 47). The only post-intervention significant finding indicated an improvement in children’s skillfulness in floating on their back without help. The limited changes in this multi-component program suggested that such interventions need to be longer in duration, intensity, and be required to reduce attrition.
Swimming Without Fear: Equitable Instruction
Authors: Khatchaturian Rubina , Stillwell Belinda
Published: March 2022

A qualitative single-subject exploratory case study approach was used to examine the effectiveness of an intervention process to assist a 30-year-old female in reducing her fear of water. During the 18-week intervention, systematic desensitization was utilized in conjunction with multiple data sources to determine its success. Data sources included the Spielberger State-Trait Anxiety Inventory (STAI), semi-structured interviews, swimming skills tests, collages, and participant and researcher journals. Data analysis examined changes in scores for the STAI and swimming skills tests while an inductive data analytic strategy was applied to organize and make sense of the interviews, collages, and participant journal entries. A researcher’s journal was kept confirming major findings. Results showed a decrease in fear as documented by interviews, participant journal entries, and the post-collage. No differences in scores were noted for the STAI and swimming skills tests. These findings suggest that cognitive and psychological progress was made by the participant; however, more time was needed to transform this progress into performing physical skills in the water.
Effective Lifeguard Scanning: A Review
Authors: Langendorfer Stephen , Pia Francesco , Beale-Tawfeeq Angela
Published: March 2022

The purpose of this scientific review was to address the question of what evidence-based visual surveillance/scanning skills exist in the peer-reviewed scholarly literature. It is well known that lifeguards spend a majority of their on-duty time surveying bathers and swimmers in the water. Lifeguards need to quickly distinguish among swimmers in distress and drowning persons from other bathers in order to rapidly come to their aid to prevent drowning. To be able to accomplish this task, Signal Detection Theory reveals that lifeguards need specific and extensive training in identifying the behavioral patterns associated with drowning persons and swimmers in distress. A typical drowning is not what has been popularized in the press and movies that shows a person calling for help and waving his or her arms about. Instead, drowning victims usually demonstrate the instinctive drowning response in which they are in a vertical position in the water, unable to call out because the mouth is underwater and arm and leg movements are ineffective in keeping them near the water’s surface. The literature revealed that expert lifeguard observation, scanning, and surveillance skills need to be acquired through planned systematic practice to identify the presence of the instinctive drowning response among bathers.

Morfologi dan kandungan unsur zeolit yang telah teraktivasi dan termodifikasi diuji dengan SEM-EDS. Hasil penelitian menunjukkan bahwa komposisi mineral pada zeolit setelah aktivasi terjadi kenaikan yang signifikan pada Na dan Si. Hal ini juga dikuti dengan pengotor pada area permukaan zeolit menjadi berkurang. Jumlah persentase unsur perak yang terendah ditemukan pada kelompok zeolit dengan modifikasi AgNO3 0,025 M dan jumlah persentase unsur perak yang tertinggi ditemukan pada kelompok zeolit dengan modifikasi AgNO3 0,1 M. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa aktivasi zeolit alam dapat menghilangkan material-material pengotor yang terdapat pada zeolit sehingga akan memudahkan modifikasi zeolit dengan ion perak. Jumlah unsur ion perak akan meningkat seiring dengan meningkatnya konsentrasi larutan perak nitrat yang digunakan.

Обобщены результаты геохимических поисков кобальт-медно-никелевых руд в западной части Кувалорогской интрузии никеленосной кортландит-норитовой формации, расположенной в южной части Камчатского срединного массива (КСМ). Выделена ведущая ассоциация химических элементов: Ni, Cu, Co, Cr. Элементный состав вторичных ореолов рассеяния соответствует составу рудных образований. Установлена тесная корреляционная зависимость между никелем, медью, кобальтом и хромом во вторичных ореолах рассеяния. При проведении поисковых работ на сульфидные кобальтмедно-никелевые руды наибольший интерес представляют комплексные аномалии никеля, кобальта и меди. В связи с тем, что в пределах КСМ нередко встречаются образования ультраосновного и основного состава, в которых никель и кобальт образуют изоморфную примесь в породообразующих силикатных минералах, особое значение имеет наличие ореолов меди, которая служит индикатором именно сульфидной минерализации.

The results of geochemical searches of cobalt-copper-nickel ores in the western part of the Kuvalorog intrusion of nickeliferous cortlandite-norite formation located in the southern part of the Kamchatka middle massif (KSM) are generalized. The leading association of chemical elements: Ni, Cu, Co, Cr. The elemental composition of secondary dispersion halos corresponds to the composition of ore formations. A close correlation between nickel, copper, cobalt and chromium in secondary scattering halos has been established. When conducting prospecting for sulfi de cobalt-copper-nickel ores, complex anomalies of nickel, cobalt and copper are of greatest interest. Due to the fact that ultramafi c and basic compositions are often found within the KSM, in which nickel and cobalt form an isomorphic impurity in rock-forming silicate minerals, the presence of halos of copper, which serves as an indicator of sulfi de mineralization, is of particular importance.
