Overview of Family Education and Culture: Masculinity Male Dancer
Authors: Rizky Prawitha Fatia , Rahmawati Rahmawati , Maulid Pradipta Baricza
Published: February 2023

Gender is a characteristic difference between women and men that are formed from the culture learned and socialized since childhood. Gender characteristics give rise to the notion that men must be masculine, and women must be feminine.  The existence of stereotypes about gender roles culturally causes someone who has a profession that is opposite to gender to be considered inappropriate. For example, male dancers are considered not masculine because of society's views. This study wants to describe how male dancers maintain their identity as male and masculine by social perception, the type of masculinity of each subject, and the reasons for respondents choosing the profession of being a dancer. The research method used was a qualitative study in the form of interviews and observations of 3 male respondents who work as towing workers.  The theory is used based on Tuncay stating that masculinity can be defined socially as a way to become a man who is defeated into 11 elements. The type of masculinity uses four configurations of masculinity in the masculinity hierarchy and a special learning theory approach in career selection by Krumboltz.  From research results known that all respondents still show their masculinity without being influenced by the profession they choose. For respondents to be attractive is what they like. It can be interpreted that one's prophesied does not always affect one's level of masculinity or femininity. Therefore, in the concept of family education, introduction to the profession does not only contain achievement in education but also includes the socialization of values for the development of both self-concept and personality. The importance of family education in the introduction about gender identities and roles in children is a way not to be affected by the stereotypes of gender roles that apply in society but to see the needs of children in self-development and personality.

Published: February 2023

Developments in technology and culture affect a person's attitude and lifestyle. Lifestyle describes the "whole person" who interacts with his environment. One of the trendy lifestyles in demand by various people, including students, is the modern lifestyle. Modern lifestyles influence consumers' consumption decisions because good images will arise if we can follow this lifestyle. Especially in social problems, where to hang out, and style in appearance. So, a person's lifestyle is related to his association and social norms that are carried out in the surrounding environment. This study aimed to determine the relationship between the influence of lifestyle on student association and social norms. This research uses a quantitative approach with a correlational study. Respondents in this study were male students at a state university in Banten, Indonesia, which consisted of the Faculty of Law, Faculty of Medicine, Faculty of Teaching and Education, Faculty of Engineering, Faculty of Business Economics, Faculty of Agriculture, Faculty of Social and Political Sciences, totaling 115 people. Data collection uses a VALS scale questionnaire (adaptation). The results of this study indicate that there is an influence of lifestyle on association and social norms. A simple lifestyle following the circumstances of the respondents influences associations that do not require a "brand image" or require branded goods in their association. As well as influences social norms as well. If lifestyle changes, then the behavior shown will also affect the social norms that it does.

Published: February 2023

The development of noble character, especially the awareness of protecting the environment, can be optimized through the internalization process in learning. Children's literary media is an effective medium, especially applied to elementary school-aged children at the golden age of character planting. Stories in children's literature can dialogue life in an interesting, concrete, and contextual way. The fable entitled "The Story of a Seagull and the Cat Who Teaches It to Fly" by Luis Sepulveda is one of the translated fables with the theme of environment and family, which is considered to have the potential to be used as a learning resource for environmental education. Research that attempts to analyze the environment's value in fables and its use as a learning resource in the era of the MerdekaBelajar(independent learning) curriculum is still very limited. This research aimed to; 1) describe the value of environmental education in the fable "The Story of a Seagull and the Cat Who Teaches It to Fly" by Luis Sepulveda; 2) describe the use of fables as a learning resource for elementary school students; 3) describe its relevance to the profile of Pancasila students in the independent learning curriculum. This research is qualitative, using a text study approach and descriptive analysis. This study showed that this fable can be used as a source of learning materials for elementary school students following the theories that support student development and learning approaches, such as; meaningful learning and constructivism, as well as relevant to the proclamation of the Pancasila student profile in the Merdeka Belajar(independent learning) curriculum. The implication of this study is a recommendation for developing children's literature-based learning media to internalize environmental awareness characters

Authors:   Department of Computer Science and Engineering, Gandhi Institute of Technology and Management-Visakhapatnam, Andhra Pradesh 530045, India, Singh Prem Kumar
Published: February 2023

Recently, a problem is addressed while dealing the data with Non-Euclidean Geometry and its characterization. The mathematician found negation of fifth postulates of Euclidean geometry easily and called as Non-Euclidean geometry. However Riemannian provided negation of second postulates also which still considered as Non-Euclidean. In this case the problem arises what will happen in case negation of other Euclid Postulates exists. Same time total total or partial negation of Euclid postulates fails as hybrid Geometry. It become more crucial in case the data is unknown, incomplete or exists beyond the three-way space as heteroclinic pattern. To understand this problem, the current paper tried to distinguish Euclidean, Non-Euclidean, Anti-Geometry, Neutrogeometry and Turiyam or Unknown geometry using the complement operator with an example.

Authors: McBroom Samantha , Elliott Tana , Cockerham Mona , Stankovic Vicky
Published: February 2023

Background and objective: The COVID-19 pandemic in 2020 increased the volume of patients seeking care in the Emergency Department (ED) for a respiratory crisis. Our community hospital experienced a filling of inpatient beds, leading to an overflow of admitted patients in the ED, where adequate staff (nurses, physicians, radiology, and laboratory staff), equipment, and rooms or places for patients were lacking. Times to obtain procedures that included cardiology, laboratory, and radiology performed and resulted significantly increased. Left without being seen (LWBS) is a challenge faced by EDs across the United States (US) and has become more prevalent since the COVID-19 pandemic. Best practice suggests an LWBS rate of less than 2%, but our hospital experienced an increasing rate of hitting over 5\% in January 2021. To reduce this rate, we implemented multiple rapid-cycle Plan-Do-Check-Act (PDCA) change interventions in triage and throughout the ED.Implementation/Methods: We implemented several rapid-cycle change interventions with a high-level action plan. These actions included hiring medical/surgical nurses to care for admitted patients awaiting beds, adding additional medical providers, implementing greeters, creating specialty chairs inside a major hospital thoroughfare, opening a 12-bed Admit Care Unit (ACU) adjacent to the ED, and more.Results: The rate of LWBS decreased from a high of 5.3% in January 2021 to 1.09% in January 2022.Conclusion/Implications to Practice: Patients in the ED recorded as LWBS are at higher risk for safety and quality transgressions. We continue to work toward excellent patient care by continuing to implement rapid-cycle changes in response to barriers as they arise. More research is needed to expand and rethink the process of ED throughput during pandemics and emergent national crises.

A microgrid is widely accepted as a prominent solution to enhance resilience and performance in distributed power systems. Microgrids are flexible for adding distributed energy resources in the ecosystem of the electrical networks. Control techniques are used to synchronize distributed energy resources (DERs) due to their turbulent nature. DERs including alternating current, direct current and hybrid load with storage systems have been used in microgrids quite frequently due to which controlling the flow of energy in microgrids have been complex task with traditional control approaches. Distributed as well central approach to apply control algorithms is well-known methods to regulate frequency and voltage in microgrids. Recently techniques based of artificial intelligence are being applied for the problems that arise in operation and control of latest generation microgrids and smart grids. Such techniques are categorized in machine learning and deep learning in broader terms. The objective of this research is to survey the latest strategies of control in microgrids using the deep reinforcement learning approach (DRL). Other techniques of artificial intelligence had already been reviewed extensively but the use of DRL has increased in the past couple of years. To bridge the gap for the researchers, this survey paper is being presented with a focus on only Microgrids control DRL techniques for voltage control and frequency regulation with distributed, cooperative and multi agent approaches are presented in this research.

Published: February 2023

Present study focuses over the extraction of gold via sodium cyanide (NaCN) from boulangerite ore. Since the presence of antimony hinders the extraction of gold by cyanidation therefore, the ore was first treated with sodium sulphide (Na2S) and sodium hydroxide (NaOH) to remove/minimize the antimony content. Gold extraction via cyanidation was then studied for different parameters including concentration of NaCN, time effect and influence of temperature on leaching of gold. It was observed that extraction of gold increases with increase in concentration of NaCN and ore amount. Maximum leaching of gold (52.89 - 76.53 %) was carried out at 80 oC, 100 minutes leaching time, 300 rpm and a pH level of 10.5.

Published: February 2023

This research work presents a comparative study for morphological effects of high accelerated and non-accelerated lead ions on polymers. The ions are produced using lead target by high powered pulsed Nd: YAG laser with wavelength of 1.064 µm, energy of 10 mJ, pulse duration of 12 ns, and power of 1.1 MW, at low pressure of ~10-3 torr. The acceleration voltage of 500 V is used to accelerate Lead ions on polyvinylchloride (PVC). The PVC samples are also irradiated without applying any potential, just to have a comparison of both types of irradiation. The samples were irradiated for 300 shots for each sample. The morphological changes were observed using Transmission optical microscope (Motic DMB series). The results showed the morphological changes in polymeric samples for accelerating potential of 500 V and 0 V. Long chain formation of laser accelerated lead ions is observed at 500 V as compared to the 0 V. The ion induced dragging effects are shown for 0 V which depend upon the energy of lead ions and also on the properties of the polymeric sample.

Multideck screen (MDS) has found wide applications in mineral processing industry and their performance can be evaluated on the basis of various parameters. The screen was indigenously designed with three decks of various changeable screens. The efficiency of MDS was evaluated at different parameters through efficiency equation and partition/Tromp curves. The imperfection factor and cut size was also determined. Material feed rate of 1 kg/min, 2 kg/min and 3 kg/min; screen angle of 7°, 10° and 13°; aperture size of 2 mm, 1mm and 0.3 mm in the three decks were taken into account. The results showed that the efficiency of MDS improves with increasing screen angle and aperture size whereas it reduces with increasing feed rate. The cut size value improves with increasing screen angle and aperture size whereas it reduces with increasing feed rate. The imperfect factor value reaches zero with increasing screen angle and aperture size while value of imperfect factor increases with increasing feed rate. The maximum efficiency was found approx. 95% at screen angle of 13°, feed rate of 1 kg/min and aperture size of 2 mm.
Analytical models for gas production in a shale reservoir: A review focusing on pore network system
Authors: Abbas Muhammad Villayat , Shoaib Muhammad , Houady Alshmlh Nasir Atallah , Ahmad Shahid Arshad Shehzad , Kim Hyung-Mok
Published: February 2023

Shale gas reservoirs may contain pores with different origins (; natural or induced) and scales. They can be divided into four groups, inorganic porosity, organic porosity, natural micro-fractures porosity and artificially created fractures porosity. The inorganic porosity is the void spaces within matrix of clay, pyrite, silica and other non-organic minerals. The organic porosity is the void space that remains in organic matter after conversion the kerogen to gas and oil. Organic matter in the form of kerogen is finely dispersed within inorganic matrix and contain void spaces (organic porosity). Micro-fractures network contains void spaces (natural micro-fractures porosity) and pore network system is also formed after creation of hydraulically induced fractures (artificially created fractures porosity). Simulating gas production from shale gas is a complex process due to interaction of fluid with various pore scales. In the current research work, shale gas transport through complex porous network is reviewed. Transport mechanism for free and adsorbed gas in dispersed organic nano-pores is combination of both Darcy and non-Darcy phenomena. Slippage of gas molecules occurs in organic pores and desorption of gas molecules occurs as the reservoir pressure depletes. The combined flux from organic pores is transported into inorganic pores then transported into micro-fractures network which can be exploited if hydraulically induced fractures are created in the vicinity of wellbore. It is a huge challenge to model gas production from shales due to presence of multi-scaled porosities. Slippage effects and desorption further add to the complexity in shale gas reservoirs. Analytical models, presented in the current review paper, incorporate complexities in shale gas reservoirs so that production from shale gas can be modeled precisely.
Applications of wireline formation testing (WFT) and downhole fluid analysis (DFA): Reviewing the importance of this technology in reservoir evaluation
Authors: Alshmlh Nasir Atallah Houady , Abbas Muhammad Villayat , Shahid Arshad Shehzad Ahmad
Published: February 2023

Wireline formation testing (WFT) is an important aspect in both exploration and production phases for reservoir evaluation. WFT tools can directly measure the formation pore pressures and then the pressure profiles are used to identify the type of pore fluids, identify the fluids density, fluid contact estimation, depletion and overpressure quantification, detection of continuity and connectivity of the reservoir in both the lateral and vertical directions. WFT is mostly used to evaluate formation permeability and taking fluid sampling.
The new generation wireline formation sampling tools include a downhole fluid analyzer (DFA), which can analyze the composition of fluids in real-time and under in-situ conditions and also can measure the spectra of crude oil. So, in result, it is possible to identify fluid compositional variation and reservoir vertical compartmentalization. The analysis of fluid composition depends on the optical absorption, and the mass fraction estimation for the three groups of hydrocarbons: methane (C1), C2-5, and C6 + along with CO2 as well. Also, it provides formation fluid properties like gas oil ratio (GOR), density, viscosity, and resistivity. The DFA results are subsequently validated and modified by laboratory analysis on the fluid samples attained from the formation.
The potential advantage of early measurements demonstrates that the DFA is a good decision-making solution in early stage without waiting for the lab result for months. Also, early DFA measurements are important in completion designing and well testing, the establishment of fluid gradients in reservoirs and connectivity, identifying and validating fluid distributions and reservoir structures.
Corrosion behavior of electrophoretically deposited boron nitride nanosheets on copper
Authors: Nadeem Aamir , Raza Mohsin Ali
Published: February 2023

The prime purpose of this research study is to determine the possibility of corrosion protection offered by boron nitride nanosheets (BNNSs) coated on pure Copper (Cu) strip through electrophoretic deposition (EPD). BNNSs suspension was developed by sonicating hexagonal boron nitride in isopropyl alcohol for 35 h prior to centrifugal partitioning of the supernatant solution, which contained BNNSs having thickness of ca. 11 nm as shown by atomic force microscopy. BNNSs deposition on copper substrate was processed in an EPD electrochemical cell arrangement keeping Cu metal as cathode and platinum as anode. The consequent BNNSs coating on the substrate was critically confirmed through series of microscopies adopting scanning electron, atomic force, and Fourier transform infrared. Energy dispersive x-ray analysis and x-ray diffraction techniques inferred the characterization positively. Tafel analysis and electrochemical impedance spectroscopy both were implied in order to evaluate Â the corrosion behavior of coatings developed on substrate copper. The former confirmed an approximate sixfold enhancement in  anti-corrosion capacity of copper protected by BN nanosheets than its bare form. The later, EIS analysis indicated a high impedance and charge transfer resistance ability of BNNSs coatings.

Menurut tradisi Bali, para penari Rejang Dewa harus gadis  yang belum menikah, gerak-gerak tarinya sangat sederhana, lemah gemulai, yang dapat dilakukan secara berkelompok atau masal, dan penuh dengan rasa pengabdian kepada leluhur dan para Dewa. Tari Rejang Dewa merupakan salah satu tarian upacara yang dikenal oleh kalangan masyarakat Bali yang biasa digunakan pada upacara piodalan.

Pendidikan bukan sekedar konsumsi ilmu tetapi juga merupakan investasi produktif dalam masyarakat. Proses pendidikan sejatinya merupakan proses pembudayaan, sehingga pendidikan adalah perjalanan menuju proses pembiasaan. Akan tetapi, sering sekali terdapat kesalahan yang menganalogikan bahwa pendidikan hanya sebatas proses transfer ilmu. Bahkan secara sempit, pendidikan hanya dimaknai secara sempit sebatas pendidikan formal yang terikat oleh institusi resmi. Proses pendidikan yang dirasa mampu menjawab kebutuhan pasar, yakni konsep ‘kolaborasi’ antara pendidikan formal dengan pendidikan non-formal yang merupakan ‘penggalian’ potensi melalui aktualisasi diri. Sinergisitas antara pendidikan formal dan non formal dapat menjadi media dalam pemetaan potensi diri.  Dengan demikian sinergisitas keduanya mampu memunculkan keselarasan ‘balancing’ dalam diri pribadi.

Pendidikan non formal yang menjadi dasar dalam pendidikan karakter yaitu pelatihan tari Rejang Dewa pada anak usia dini. Tujuannya adalah untuk memperkenalkan makna, fungsi, dan media pendidikan yang menjadi acuan nilai-nilai pendidikan karakter dikarenakan di dalamnya terdapat berbagai pesan moral, gagasan yang terkonsep pada Tri Hita Karana.

Published: February 2023

O presente artigo aborda as propriedades mecânicas de aços com baixo teor de carbono e as alterações que podem ser causadas pelo processo de soldagem em conjunto com diferentes tratamentos térmicos. O objetivo é analisar de forma experimental a diferença que os procedimentos aplicados ao material causam em suas propriedades e microestrutura. O desenvolvimento de trabalhos como este possibilita um fácil acesso ao conhecimento das propriedades finais dos materiais que foram submetidos a diferentes processos de fabricação, o que permite saber quais são as aplicações ideais e as não recomendadas na elaboração de projetos e protótipos.

La ciencia no pretende ser verdadera, ni, por tanto, final e incorregible, cierta, como en cambio, hace la mitología. Lo que afirma la ciencia es: Que es más verdadera que cualquier modelo no científico del mundo; la ciencia es capaz de probar, sometiéndola a contrastación empírica la pretensión de verdad. Es más, la ciencia es capaz de descubrir sus propias deficiencias, de construir representaciones parciales de las estructuras del mundo para que sean cada vez más adecuadas.

En esa perspectiva, el vocero del desarrollo científico, tecnológico y humanístico de la Universidad Nacional de Huancavelica Siglo XXI, en su trajinar académico, donde se viene divulgando los resultados del quehacer científico de los miembros de la comunidad universitaria, en la presente edición pone a consideración de la comunidad interesada en el saber científico, artículos relacionados con problemáticas afines a las ciencias empresarias y de ingeniería; tales como: “Efectos del Programa Reactiva en la Fuerza Laboral de MYPES en Regiones Pobres”; “Empoderamiento Económico en Mujeres del distrito de Paucará y Acobamba de la Región de Huancavelica” y “Correlaciones Fenotípicas y Medidas Biométricas en Ovinos de la Región de Huancavelica”. Artículos de transcendental importancia para los miembros de la comunidad científica, puesto que, son documentos resultado de procesos de investigación, originados por problemáticas palpitantes de la región, el país y el mundo.

Es así que, en nuestra revista Siglo XXI, los autores y coautores de los artículos científicos objetivizan sus ideas por medio de las proposiciones científicas y/o tecnológicas que pueden ser percibidos y entendidos por todo el que lo desee e interese; toda vez que la conversión del conocimiento personal en conocimiento científico va acompañada por la representación del primero con la ayuda de un conjunto de señales materiales convencionales que pertenecen a uno o más lenguajes propias de una determinada disciplina científica.

Gracias al diseño, implementación, concretización y evaluación de cada artículo científico, los lenguajes científicos contenidos en cada uno de ellos, se crean, modifican y difunden como parte de las teorías y procedimientos científicos; consiguientemente, su lectura, relectura, análisis y dilucidación de los mismos, no pueden realizarse independientemente del de las teorías y procedimientos inherentes a las disciplinas científicas a las cuales pertenecen los artículos propuestos en la presente edición de Siglo XXI.

Finalmente, reiteramos nuestra invitación a todos los interesados en difundir sus resultados de las investigaciones realizadas en cada uno de los espacios disciplinarios de la ciencia, la tecnología y las humanidades a remitir sus artículos científicos para ser publicados en nuestro vocero oficial de ciencia y tecnología de la Universidad Nacional de Huancavelica. Lo esperamos.

Synchronizing decisions: A dynamic programming, real option framework for New Product Development with stage-to-stage correlations
Authors: Kumiega John
Published: February 2023

Much research has investigated the application of real options to staged, new product development projects. Still, this literature has not addressed an important intuition�that bad projects may stay bad. A new product development project or a technology startup backed venture capital may include stage-to-stage dependencies. Its �state� at one gate may influence the transition probabilities at later gates. We develop a novel real option model that captures this intuition using dynamic programming and serial correlations. In a subsequent paper, we introduce partial derivatives similar to the Greeks that we named �control maps�. These control maps will assist the firm�s management to assess the financial impact of resource reallocations to project success factors. Such reallocations have the intent of turning bad projects into good ones. Thus, the proposed framework enables management to synchronize its management decision with financial ones.

Social media has become an integral part of our lives as Platforms like Facebook, Twitter, Instagram are conceived as a means of direct consumer interaction. Here, the problem identified is that although, these mediums have been promising their consumers some major concerns like privacy and censorship resistance, the promise has not been kept. Keeping the profitability in mind, social media platforms are risking the privacy of consumers. Centralized nature of these mediums is the main reason behind these issues. So, the objective of the project is to build an application in a decentralized way so that consumers can communicate without censorship while protecting their privacy.

Published: February 2023

Objective: To assess the accuracy of application of diffusion weighted imaging in the diagnosis and evaluation of acute onset ischemic strokes. Study Design: Cross sectional validation study. Place and Duration: Department of Diagnostic Radiology, Mardan Medical Complex, Hospital, Mardan from 15th October 2020 to 15th April 2021. Methodology: Patients whose presentation was highly suggestive of acute stroke, were undergone a non-contrast Computed tomography scan of the brain immediately by Asteion VP single slice. Those found negative for acute hemorrhage on Computed tomography images were subjected to Magnetic resonance imaging on Achieva 1.5 Tesla. Diffusion-weighted imaging technique of MRI scan was done in addition to the conventional T1W, T2W, and FLAIR scans of MRI which were also done. DWI was performed as early as possible not later than 24 hours after symptoms onset. Both DWI imaging technique and conventional routine T1W, T2W and FLAIR scans of MRI were repeated after 7 days. Results: The mean age of the sample was 57.6 + 5.9 years. On Diffusion-weighted imaging, stroke was observed in 60.2% of patients. Later on follow-up conventional magnetic resonance imaging scans were done after 7 days, stroke was recorded in 69.9% of patients confirming the diagnostic accuracy of DWI imaging in sub-acute stroke in early diagnosis. Conclusion: Conventional MRI scans like T1W, T2W and FLAIR have diagnostic accuracy only after some days. It has poor diagnostic accuracy in early onset sub-acute ischemic strokes. On the other hand, DWI imaging scans of MRI can be a useful tool for early detection of ischemic strokes as it diagnosed stroke in 60.2% of patients which were later confirmed by conventional MRI scans done after 7 days. Conventional MRI scans have high accuracy of detection of strokes but only after some days. So DW1 imaging may be applied for early diagnosis of strokes in sub-acute onset strokes.
