Authors: Bhanawat Hemant , Bharti Hridaya Raj , Srivastava Ambar
Published: May 2023

A study carried out with a random sample of 105 beneficiary households under Japan International Cooperation Agency (JICA) project in Himachal Pradesh mainly to examine the extent of diversification and increase in income of the farmers reveals that on average about 68% of operational holding in the possession of farmers was covered under the culturable command area of the total cropped area of 0.88 ha per household, and around 47% was diversified to the cultivation of vegetable crops. On the whole, the implementation of JICA project in different sites under study has led to an increase in income of the target income of Rs 125000 to be accomplished by the end of the project. Furthermore, the detailed analysis carried out reveals that gross average annual farm income is expected to rise based on findings, and the study strongly suggests diversification towards vegetable crops to reduce risk since per hectare income from vegetable crops is expected to increase further as the process of diversification gains momentum in the next two years of the project.

Authors: Chung Gil , Viveros Robert , Lee Charles , Soukhojak Andrey , Pushkarev Vladimir , Cheng Qian Yu , Raghothamachar Balaji , Dudley Michael
Published: May 2023

Correlation of X-ray topography and production line defect inspection tools has demonstrated the capability of in-line tools to differentiate between geometrically comparable basal plane slip bands (BPSB) and bar stacking faults (BSF) on 4H SiC wafers. BPSBs were found to propagate through epitaxial growth at high rates and with similar photoluminescence signatures to post-epitaxy BSFs. Molten KOH etching post-epitaxy provided evidence of distinguishing features between BPSBs and BSFs, suggesting that the defects were indeed correctly identified by in-line defect inspection tools pre-epitaxy.

Authors: Mu Hong Yun , Luo Yan Lei , Luo Yu , Liu Yao
Published: May 2023

In response to the problem of large energy waste in the loader actuator, a hybrid loader boom arm energy recovery and regeneration system is proposed, which adopts a supercapacitor as the energy storage element. Firstly, the working principle of the hybrid loader boom arm energy recovery and regeneration system is analyzed. Secondly, the mathematical model of the components is analyzed. Finally, AMESim is used to model the system. The simulation is carried out under typical working conditions with the LiuGong ZL50C loader as the simulation object and compared with the conventional system. The simulation results show that the hybrid power system does not affect the motion characteristics of the loader boom arm system compared with the conventional system. The hybrid power system can perform energy recovery regardless of the mode of operation, and the energy recovery efficiency reaches 55.7 %. When the system enters the hybrid mode, the supercapacitor SOC fluctuates less, and the energy regeneration efficiency reaches 90 %. The hybrid power system can effectively reduce engine fuel consumption and pollutant emissions, with the system's energy-saving efficiency of 44.4 % and CO, HC, and NOx emissions reduced by 41.1 %, 47 %, and 19.8 %, respectively. The system provides a reference for the research of energy-saving technology of the loaders, effectively reducing the operating cost of the loaders.

Authors: Gupta Abhishek , Kumar Pachar Ramesh
Published: May 2023

A hybrid signal processing technique (HSPT) is proposed in this manuscript for identification and categorization of faults in electrical transmission network. A fault indicator (FI) is suggested by decomposition of the currents by application of Alienation coefficient (ACF), Stockwell transform (ST) and Hilbert transform (HT) for identification of faults. An indicator for ground involvement during faulty condition (SGFI) is being suggested to detect the type of fault. The categorization of faults is done by utilizing faulty phase numbers and SGFI. It is found that the proposed technique is effective in identification of faults and to classify them in different scenarios together with fault on A-phase to ground (AGF), double phase fault (ABF), fault on two phases and ground (ABGF), three phase fault (ABCF) and three phase fault including ground (ABCGF). Study is done and validated on IEEE-9 bus system using MATLAB/Simulink environment. The effectiveness and applicability of the proposed technique with respect to different parameters of faults such as Fault Incidence Angle, Fault Impedance, Line loading, Generator Supply and Noise level is also checked. The results shows that proposed scheme is able to detect and classify the faults in different faulty events.
Role of Carbon Nanotubes in Expanding the Properties of Cement-Based Composites for Construction: An Overview
Authors: Katar Ihab M.
Published: May 2023

Carbon nanotubes (CNTs) have been studied as a reinforcement material for cementitious composites, with promising results. Incorporating CNTs into cement-based materials enhances the composites' mechanical, thermal, and electrical properties, as cementitious materials have limited applications due to their strain capacity and less tensile strength. CNTs have high tensile strength and modulus, along with excellent electrical conductivity. These features make them ideal for construction materials. Using CNTs in cement-based composites can improve the durability and sustainability of construction materials and provide new opportunities for advanced applications in the construction industry. The addition of CNTs to cement-based materials can improve mechanical performance, improve fire resistance and reduce carbon dioxide emissions. The incorporation of CNTs in cementitious composites is a promising area of research with significant potential for use in the construction industry. The current study's findings are expected to provide insight into the new material and its glamorous scopes for application as construction materials.
Demonstration of SiC Trench Gate MOSFETs with Narrow Cell Pitch Using Source Self-Aligned Process
Authors: Kimoto Shinichi , Iijima Ryosuke , Harada Shinsuke
Published: May 2023

The SiC trench gate MOSFET with narrow cell pitch is demonstrated using a process in which the n+ source is self-aligned to the trench gate. A minimum cell pitch of 1.6 μm, which is difficult to achieve using the conventional device structure, is easily fabricated by applying a deep n+ source and a buried interlayer dielectric structure. The cell pitch reduction indicates a beneficial trend that contributes to a decrease in the specific on-resistance and an increase in the breakdown voltage. The process and structure are promising for further improving SiC power device characteristics.
Threshold Voltage Adjustment on 4H-SiC MOSFETs Using P-Doped Polysilicon as a Gate Material
Authors: May Alexander , Rommel Mathias , Abbasi Affan , Erlbacher Tobias
Published: May 2023

To scale digital circuits, symmetric threshold voltages (Vth) for n-type transistors (NMOS) and p-type transistors (PMOS) are important. One step towards this in silicon carbide (SiC) is selecting a p-doped polysilicon (pPolySi). This implementation has been shown in this work with Vth being evaluated by five different methods. Furthermore, operating temperatures up to 500 °C and their impact on Vth were investigated. It has been successfully demonstrated that elevated temperature shifts Vth of both transistor types towards 0 V, whereas changing the gate electrode from n-doped PolySi (nPolySi) to pPolySi shifts Vth of both transistor types to more positive values. Both effects are complementary for the PMOS, reaching Vth below 4 V.

Authors: Haziq Muhaimin , Ali Norshamsuri , Falina Shaili , Kawarada Hiroshi , Syamsul Mohd
Published: May 2023

Lateral GaN devices, with a substantial critical breakdown field and increased mobility of two-dimensional electron gas (2DEG), are particularly promising for future power applications. Despite low power consumption by design, further improvements are required in numerous areas, including reliability concerns and switching loss, usually contributing to significant power loss. The research objective concerns the impact of different notch structures on the transfer characteristics of GaN-based high-electron-mobility transistor (HEMT) devices. Thirteen simulated models were produced using COMSOL Multiphysics, incorporating the electrical, structural, and piezoelectric effects of the device. From the results, notch-structure devices demonstrated better electrical characteristics than devices using conventional architecture, particularly a model with a double-notch design. Higher transconductance and maximum drain current were among the improvements, benefiting from the notch structure at the barrier layer.
Crucial Roles of SATB1 in Regulation of Thymocyte Migration after Positive Selection
Authors: Naito Taku , Ise Marii , Tanaka Yuriko , Kohwi-Shigematsu Terumi , Kondo Motonari
Published: May 2023

Double-positive thymocytes that have passed positive selection migrate from the cortex to the medulla, where negative selection and the development of thymic regulatory T cells (tTregs) take place. Medullary thymic epithelial cells (mTECs) play important roles in these selections, and their differentiation and maintenance depend on interaction with positively selected CD4+ single-positive cells. Therefore, migration and differentiation after positive selection must be coordinated to establish immune tolerance. However, the regulatory mechanisms of these processes are not fully understood. SATB1 is a genome organizer highly expressed in double-positive thymocytes, and SATB1 deletion causes various defects in T-cell development, including impaired positive and negative selection and tTreg differentiation. Here, we show that SATB1 is critical for temporally coordinated thymocyte trafficking after positive selection in mice. Satb1 knockout (ΔSatb1) led to precocious thymic egress caused by augmented S1pr1 upregulation in positively selected thymocytes, accompanied by lower induction of Ccr7, Tnfsf11, and Cd40lg. Altered thymocyte trafficking and functionality affected the differentiation of mTECs and, in turn, tTreg differentiation. Thus, SATB1 is required to establish immune tolerance, at least in part, by ensuring timely thymic egress and mTEC differentiation.

Objective: To evaluate the utility of infantile BCG vaccination history in predicting stage and grade of tumours in non-muscle invasive bladder cancer (NMIBC). Materials and methods: We retrospectively analyzed data from patients from a single center who were diagnosed with new NMIBC and underwent transurethral resection of bladder tumour (TURBT) between 2017 and 2022. We assessed BCG immunization status with various demographics and comorbidities, as well as tumour recurrence, progression, stage, and grade. Results: A total of 188 patients met the inclusion criteria for our study. The mean age of patients at the time of diagnosis was significantly lower in those that had been immunized with BCG (71 ± 9) than those who had not (77 ± 10) (p < 0.0001). History of BCG immunization did not correlate with sex, history of diabetes mellitus (DM), prior history of intravesical BCG treatment, and tumour recurrence, progression, stage, and grade. Conclusions: History of infantile BCG vaccination did not correlate with the depth of invasion and/or the grade in patients with non-muscle invasive bladder cancer. Patients that received infantile BCG vaccination were significantly younger at the time of diagnosis of NMIBC.

Published: May 2023

Objective:

To identify the association between serum albumin levels and disease severity among adult patients with dengue in mainland China.

Methods:

This retrospective cohort study analyzed the data of adult patients (aged ≥ 18 years) hospitalized with laboratory-confirmed dengue in a tertiary center for infectious diseases from 2013 to 2019 in mainland China. Serum albumin levels were estimated and compared between patients with severe dengue and non-severe dengue. Additionally, the association between serum albumin levels and severe dengue was evaluated using a generalized linear model [relative risks (RR)]. Multivariate logistic regression analysis was performed to identify the potential predictors of severe dengue.

Results:

Overall, 1568 patients were included in this study. Of these patients, 34 (2.17%) developed severe dengue. The median serum albumin levels were significantly lower in patients with severe dengue than that in those with non-severe dengue (33 g/L vs. 37 g/L, P<0.001). After adjustment for age, sex, and comorbidities, hypoalbuminemia (RR 4.877, 95% CI 2.193-11.461, P<0.001) was found to be a predictor of severe dengue. Serum albumin levels (OR 1.303, 95% CI 1.161-1.462, P<0.001)] and age (OR 1.038, 95% CI 1.017-1.061, P<0.001) were significant risk factors for severe dengue. The area under the curve for serum albumin levels to distinguish severe dengue was 0.787.

Conclusions:

Lower serum albumin levels were significantly associated with disease severity in adult patients with dengue. Hypoalbuminemia on admission resulted in at least a four-fold increased risk of severe dengue.

Authors: Samanta Sampriti , Bandyopadhyay Alapan , Bhattacherjee Sharmistha , Mukherjee Abhijit
Published: May 2023

Background:

Leprosy has been affecting humans since ancient times. A chronic infectious disease, it affects skin, peripheral nervous system, and other tissues which lead to nerve damage, pain, and visible deformities. The characteristic skin lesions of leprosy can lead to significant social stigmatization and functional impairments which can affect the quality of life (QoL).

Objective:

The present study was conducted to assess the dermatological QoL among these leprosy patients.

Materials and Methods:

An observational cross-sectional study was conducted among 122 leprosy patients who were receiving treatments at a rehabilitation center in North-Eastern India in a 3-month time period. The dermatology QoL Index (DQLI) questionnaire was used to assess the QoL among these patients. Descriptive statistics and logistic regression analyses were used.

Results:

Among a total of 122 patients, leprosy had no effect on QoL in 4.9%, small effect in 11.5%, moderate effect in 37.7%, very large effect in 43.4%, and extremely large effect in 2.5% cases. Mean DQLI score was 10.5 ± 5.1. The most affected domain was leisure and social followed by symptoms and feelings. When adjusted for predictors, age and sex were found to have a significant association with QoL.

Conclusions:

Leprosy with dermatological manifestations had a very large effect on QoL. The impairment was more than other chronic skin diseases, such as chronic urticaria, vitiligo, and psoriasis. It is necessary that periodic assessment of QoL should be incorporated into the management of leprosy patients.

Authors: Amini Zahra , Asady Hadi , Pourabdian Siamak , Forouharmajd Farhad
Published: May 2023

Introduction:

In addition to having auditory effects, sound also has nonauditory effects. Acoustic Annoyance is one of the nonauditory effects of sounds which are construed as psychoacoustic characteristics. The study at hand was undertaken to investigate the psychoacoustic characteristics of absorbents used in common earmuffs.

Materials and Methods:

In this study, four earmuffs prevalent in industries were used. The psychoacoustic characteristics of loudness and sharpness were measured and analyzed in sound levels of 75, 85, and 95 dB using an impedance tube and Va-Lab 4 software with and without absorbers. The results were analyzed with SPSS-26 software.

Results:

Results showed that the highest and the lowest increase in loudness were attributed to the EM-101 and the EM-104, respectively. In addition, with the increase in the sound level, the loudness increased. Furthermore, in 85 dB, there was no significant relationship between loudness and earmuff absorber only in the case of the earmuff EM-103. Furthermore, the highest and the lowest increase in sharpness were, respectively, attributed to the EM-101 and the EM-103. Only in the samples of EM-103 and EM-104 earmuffs at the level of 75 dB, there was no significant relationship between sharpness and earmuff absorber.

Conclusion:

Earmuffs used in industries showed different performances against the loudness and sharpness of the sound. In other words, the quality and the structure of earmuff absorber play noteworthy roles in decreasing the qualitative parameters of sound.

Published: May 2023

Aim:

The aim of this study was to evaluate the impact of patients’ characteristics on the efficacy and the safety of subcutaneous tirzepatide once-weekly in patients with uncontrolled type 2 diabetes mellitus (T2DM).

Materials and Methods:

This post hoc analysis of pooled SURPASS 1-5 randomized controlled trials narratively examined changes from baseline in hemoglobin A1c (HbA1c) and body weight and the proportions of patients who achieved the endpoint composite HbA1c with tirzepatide (5, 10, and 15 mg) across the following subgroups; baseline HbA1c (≥ 7.5% to ≤8.0% [≥48 ≤ 64 mmol/mol], ≥8.0% to ≤8.5% [≥64 ≤68 mmol/mol], and ≥ 8.5% to ≤9.0% [≥68 ≤75 mmol/mol]), baseline diabetes durations (≤ 5 years, 5–10 years, and ≥ 10 years), and age (non-elderly ≤ 60 years and elderly ≥ 60 years).

Results:

Based on diabetes duration, the mean HbA1c reduced from baseline (≥–1.87 % to ≤–2.24% [≥–20.57 to ≤–24.64 mmol/mol]) for tirzepatide 5 mg (P = 0.308), –1.89 % to –2.43% (–20.79 to –26.73 mmol/mol) with tirzepatide 10 mg (P = 0.015) and ≥–2.07 % to≤ –2.58 % (≥–22.77 to ≤–28.38 mmol/mol) with tirzepatide 15 mg (P = 0.010). Similar HbA1c and body weight reductions were observed across other subgroups (baseline HbA1c and age).

Conclusion:

Tirzepatide was consistently efficacious and safe in the broad spectrum of patients with T2DM subgroups across the SURPASS 1-5 trials.
Health literacy, medication belief, and demographic factors as correlates of medication adherence in person with diabetes mellitus
Authors: Olorunfemi Olaolorunpo
Published: May 2023

Background:

A rise in the number of people with diabetes is possible if immediate action is not taken to reverse the trend. Diabetes mellitus is a chronic medical condition that has serious health consequences for people. The goal of this study was to investigate the relationships between medication adherence, health literacy, and demographic characteristics.

Materials and Methods:

This correlational study methodology was used at the University of Benin Teaching Hospital in Benin City in 2020. The study included 180 diabetes participants. The tools used included belief about medications questionnaires (BMQ), medication adherence rating scales (MARS), and the Short Functional Health Literacy in Adults Test (STOHFLA), and used linear regression, descriptive statistics, and Spearman’s rho correlation.

Results:

The researcher discovered that 66.7% of the people lacked adequate health literacy, and MARS analysis revealed that medication adherence was low. Age and income level both had relationships with medication adherence, but marital status, and education did not. The researcher also found a link between medication adherence, health literacy, and medication belief using P-values of 0.004 and 0.002. The regression model indicates that age, medication belief, health literacy, and economic and income level are predicting factors for medication adherence.

Conclusion:

Nurses and hospital administrators need to focus more on the health literacy, age, income level, and health beliefs of their patients because there is evidence that these aspects are statistically associated with medication adherence.
General path integrals and stable SDEs
Authors: Baguley Samuel , Döring Leif , Kyprianou Andreas
Published: May 2023

The theory of one-dimensional stochastic differential equations driven by Brownian motion is classical and has been largely understood for several decades. For stochastic differential equations with jumps the picture is still incomplete, and even some of the most basic questions are only partially understood. In the present article we study existence and uniqueness of weak solutions to

\operatorname{d} Z_t=\sigma(Z_{t-})\operatorname{d} X_t

driven by a two-sided

\alpha

-stable Lévy process, in the spirit of the classical Engelbert–Schmidt time-change approach. Extending and completing results of Zanzotto we derive a complete characterisation for existence and uniqueness of weak solutions for

\alpha\in(0,1)

. Our approach is not based on classical stochastic calculus arguments but on the general theory of Markov processes. We prove integral tests for finiteness of path integrals under minimal assumptions.

From Bibliometrics to Altmetrics: Examining the Relationship Between Citation Count and Altmetric Score in Publications on Artificial Intelligence
Authors: Maatouk Yasser
Published: May 2023

In this research work, we studied two main research questions. First, we explored how artificial intelligence (AI) publications are seen on various altmetric platforms. Second, by looking at publications in the field of AI, we examined whether bibliometrics and altmetrics are correlated. For each of the 8000 AI publications on the Web of Science (WoS) database with altmetric scores, we recorded the citation counts and altmetric scores. Pearson’s correlation for the two lists of variables was found to be 0.2. This result is near to zero, indicating that there is weak correlation between citations and altmetric attention score. Further, in the two top lists of publications according to citation count and altmetric score, respectively, we found only one paper in common. For the time being, altmetric scores are weakly correlated with citation in the AI publications. In terms of research impact, altmetrics should be regarded as complementary to traditional bibliometrics rather than as a replacement measure. Beside these results, this article gives an overview of this area of research (scientometrics and informetrics). All related terminologies are defined, and for the purpose of this study we focus on bibliometrics and altmetrics.

Enhancement of kaolin clay soil for civil engineering application using rice husk ash and sawdust ash geopolymer cements
Authors: Salahudeen A. B. , Kpardong N. S. , Francis P. M.
Published: May 2023

These days, good quality road construction materials are scarce and their haulage to the construction site is expensive. When unsuitable materials are encountered during flexible pavement construction, the most technical and economical option is always to improve them to meet design standards. One of these deficient materials mostly encountered in tropical regions is kaolin clay soils. Cement and lime that are traditional deficient soil improvement agents are on high demand therefore have kept the cost of engineering construction financially high. Thus, the use of agricultural wastes such as sawdust and rice husk as alternative construction materials will considerably reduce the cost of construction and as well mitigate the environmental hazards caused by the wastes and cement production. This study investigated and compared the performance of rice husk ash (RHA) and sawdust ash (SDA) geopolymer cements in improving the geotechnical properties of kaolin clay soil used for flexible pavement construction. All laboratory experimental tests were carried out in accordance with British Standard (BS) 1377 and BS 1924 for natural and modified kaolin clay soil samples respectively. Soil samples were mixed with geopolymer cement at stepped concentrations of 0, 4, 8, 12, 16 and 20% by dry weight of soil. Results indicated that the plasticity index value of the natural kaolin clay of 18.52% was reduced to 7.24% at 20% RHA geopolymer cement content. The unconfined compressive strength of the natural soil was improved by 600 and 400 % by RHA and SDA geopolymer cements respectively. It was concluded that the use of up to 20% RHA and SDA geopolymer cements can efficiently and eco-friendly improve kaolin clay for flexible pavement foundation purpose.

This paper presents a Fuzzy Logic Controller-based energy management system (EMS) to control hybrid energy sources. The design is a single-phase and grid-tied system sized to handle the system's diverse load demands. The design system consists of photovoltaic modules, a grid source and a single-phase standby generator. The system uses energy produced by the PV modules (using Perturbation and Observation MPPT to maximize energy generated from the modules) and power stored in the Energy Storage Unit (ESU) to fulfil the various load needs while prioritizing the selling of excess energy to the grid. The fuzzy controller controls and manages the highlighted operational activities and prevents the ESU from overcharging and undercharging. Simulink is adopted to implement the proposed system within the simulation period; as the irradiation increased from 0W/m2 to 100W/m2, the grid's power supply dropped from 6000W to 4000W because of the amount of PV power generation between 0.6s and 0.8s. The photovoltaic module contributed to the system's overall power consumption while keeping the DC bus voltage between 396V and 406V. The EMS using the fuzzy logic controller provides high levels of energy security, system effectiveness and O &M cost optimization. It has also offered a consistent and uninterrupted power supply.

Kalp yetersizliği, sık hastaneye yatışlara sebep olması, yüksek morbidite ve mortalite oranları nedeniyle ciddi bir sağlık sorunudur. Kalp yetersizliği tedavisinin başarıya ulaşabilmesi ve semptomların kontrol altına alınabilmesi için etkili hemşirelik bakımının verilmesi gerekmektedir. Kalp yetersizliğinde hemşirelik bakımının temel amaçları; semptom kontrolünü sağlamak, egzersiz kapasitesini arttırmak, farmakolojik tedavinin etkinliğini değerlendirmek, komplikasyonları önlemek ve yaşam tarzı değişikliklerini sağlamaktır. Hemşirelikte kuram ve modellerin kullanılarak bakıma yansıtılması, hemşirelik bakım kalitesinin arttırılması, holistik ve etkili hemşirelik bakımının sağlanması açısından oldukça önemlidir. Hemşirelik kuramcılarından Virginia Henderson temel insan gereksinimlerine dayandırdığı kuramında, bireyi biyo-psiko-sosyo-kültürel ve gelişimsel gereksinimler açısından ele almaktadır. Hemşirelik mesleğinin özünü iyi yansıtması ve birey odaklı olması açısından kuramın, kalp yetersizliği olan hastaların bakımında kullanılabileceği düşünülmektedir. Bu olgu sunumunda, kalp yetersizliği tanılı bir hastanın bakım gereksinimlerinin Henderson Hemşirelik Modeli doğrultusunda ele alınması ve hastaya özgü hemşirelik bakım planı sunulması amaçlanmıştır.

İçe Dönük Bir Tipin Serencamı: Fahim Bey ve Biz Romanı
Authors: KAROĞLU İlhan
Published: May 2023

Abdülhak Şinasi Hisar, ilk romanı Fahim Bey ve Biz’de 19. yüzyıl sonlarından II. Meşrutiyet’e uzanan dönemde sınırlı düzeyde de olsa Batı kültürüne aşina bir karakterin, muhitiyle ilişkisini resmeder. Bursalı bir eşrafın oğlu olarak küçük memuriyetlerle İstanbul’da tutunmaya çalışan Fahim Bey, Londra sefaret kâtipliği sonrası pamuk girişimi için sermayedar bulamayınca hayali şirket kuracak derecede bir hülya adamıdır. Henüz gençken kendine özgü tercih, ilgi ve hevesleriyle dikkat çeken Fahim Bey, günün koşullarına göre oluşmuş toplumsal ve kamusal düzene yabancıdır. İçe dönük bir mizaç olarak dış dünyayı kendi tasarı ve yargıları üzerinden değerlendirir, tercihleri konusunda hiçbir şüphe duymaz. Gençliğinden itibaren arkadaş ve çevresi tarafından tuhaf bulunduğu, eleştiri ve alaylara maruz kaldığı halde yaşam tercihlerinde herhangi bir değişikliğe yönelmez. Sınırlı dost çevresi dışında yalnız bir yaşam sürse de bu durumdan şikâyetçi değildir. Dış dünya ile hülyaları arasında uyum yakalayamayan bir içe dönük olarak kendini insanlardan gittikçe soyutlayan Fahim Bey, Carl Gustav Jung’un psikolojik analizlerine göre incelemeye uygun bir karakterdir. Jung’un kavramsallaştırdığı persona (maske) arketipi; kişinin sosyal ve kamusal alanda kendisinden beklenen davranış biçimine uyum göstermesi şeklinde ifade edilebilir. Jung psikolojisinde kişinin içe dönük ya da dışa dönük oluşu dış dünyanın koşullarına uyum göstermesinde de belirleyici bir etmendir. Bu çalışmada Jung psikolojisinden hareketle Fahim Bey karakterinin, personasıyla niçin denge kuramadığı; hangi etmenlerden ötürü toplumsal ve kamusal düzenle uyuşma kabiliyeti gösteremediği ortaya konulmaya çalışılmıştır.
HyperATL*: A Logic for Hyperproperties in Multi-Agent Systems
Authors: Beutner Raven , Finkbeiner Bernd
Published: May 2023

Hyperproperties are system properties that relate multiple computation paths
in a system and are commonly used to, e.g., define information-flow policies.
In this paper, we study a novel class of hyperproperties that allow reasoning
about strategic abilities in multi-agent systems. We introduce HyperATL*, an
extension of computation tree logic with path variables and strategy
quantifiers. Our logic supports quantification over paths in a system - as is
possible in hyperlogics such as HyperCTL* - but resolves the paths based on the
strategic choices of a coalition of agents. This allows us to capture many
previously studied (strategic) security notions in a unifying hyperlogic.
Moreover, we show that HyperATL* is particularly useful for specifying
asynchronous hyperproperties, i.e., hyperproperties where the execution speed
on the different computation paths depends on the choices of a scheduler. We
show that finite-state model checking of HyperATL* is decidable and present a
model checking algorithm based on alternating automata. We establish that our
algorithm is asymptotically optimal by proving matching lower bounds. We have
implemented a prototype model checker for a fragment of HyperATL* that can
check various security properties in small finite-state systems.
Hidup Beriman menurut Yakobus 1:2-8
Authors: Manullang Juanda , Lumy Aghi
Published: May 2023

Setiap orang percaya pernah mengalami pencobaan dan memiliki kisahnya masing-masing di dunia masa kini yang semakin praktis dan serba instan. Orang percaya sekarang ini ketika diperhadapkan dalam cobaan hidup yang tidak dapat diselesaikan secara instan, pada akhirnya memutuskan menyerah dengan keadaan. Iman dilupakan dan ini merupakan sebuah problem dalam kekristenan dewasa ini. Untuk itu, artikel ini menelaah pentingnya hidup yang tekun di dalam iman sebagaimana nasihat Yakobus kepada orang percaya yang menderita akibat penjajahan Romawi. Dengan menggunakan pendekatan kualitatif dan sumber-sumber literatur, penelitian ini akan menggali pentingnya hidup beriman melalui penggalan teks Yakobus 1:2-8. Kesimpulan utama yang diperoleh adalah perlunya perubahan persepektif di kalangan orang Kristen mengenai pencobaan yang harus dilihat sebagai proses penguatan iman dan jalan untuk melatih ketekunan. Hanya dengan cara itu, setiap cobaan yang dihadapi akan dilihat sebagai proses yang menumbuhkan kebergantungan dan kepercayaan yang kuat kepada Tuhan.
Book Review: Menuju Dialog Teologis Kristen Islam
Authors: Aritonang Arthur
Published: May 2023

Buku ini ditulis oleh Dr. Bambang Noorsena yang berisikan kumpulan artikel dan berbagai karya lepas Noorsena yang pernah disajikan diberbagai kesempatan sejak akhir 1997. Berbagai tulisan ini dibingkai dalam sebuah judul: Menuju Dialog Teologis Islam Kristen. Tulisan ini dilatarbelakangi oleh beban sejarah lalu, di mana dalam konteks Indonesia para pembawa agama semisal Islam diidentikan dengan Arab (Timur Tengah), sedangkan kekristenan identik dengan Barat. Menurut Noorsena, kekristenan di Indonesia sudah tercabut dari akar Timur Tengah oleh karena mengalami proses westernisasi. Dengan demikian tujuan, penelitian ini dilakukan untuk menjembatani kesenjangan hubungan Islam dan Kristen dalam dialog teologis Noorsena menawarkan wacana kekristenan Timur Tengah (Kristen Syria) di Indonesia. Secara tradisi/model Islam melestarikan tradisi/model ibadah agama Kristen Syria dan juga agama Yudaisme.
An Overview High Performance of Stress Corrosion Cracking Behavior for Aeronautic Applications
Authors: Sushmitha Evangeliene S.R , Robinson Smart D.S , Saravanan Vimala , Ramachandran M
Published: May 2023

Tensile stress combined with exposure to a corrosive environment result in a cracking process known as stress corrosion cracking (SCC). It falls in the threshold of the material's fatigue limit and dry cracking. Tensile stress can be applied directly or exist as residual stress within the material. SCC results from specific combinations of composition, environment, and stress. Processes like cold forming, welding, heat treating, machining, and grinding introduce residual stresses. Stress erosion cracking (SCC) occurs when cracks form under static tensile stress and the environment around us . It develops by the result of the interaction between mechanical stress and corrosion/oxidation reactions. The occurrence and progression of SCC depend on the materials, applied loads, and environmental conditions. Some Contributing Factors to SCC In summary, two main features of SCC are emphasized: localization and acceleration of oxidative reactions.
El desempleo y la violencia contra la mujer en Guatemala
Authors: Morales Ixcajó Leonel Humberto
Published: May 2023

PROBLEMA: Guatemala ha sido azotado por la violencia desde la colonia, las dictaduras del siglo XIX, el conflicto armado interno, hasta el llamado tiempo de paz que precede a la actualidad. La discriminación y exclusión social como una manifestación de la violencia contra la mujer tienen un impacto en el bienestar de la población, y merman la oportunidad de acceso al empleo en los mercados formales al históricamente vulnerado segmento de la mujer. OBJETIVO: analizar la participación de la mujer de Guatemala en el empleo y las consecuentes implicaciones que la violencia contra la mujer tiene en éste. MÉTODO: se utilizó el método analítico y técnicas de observación para el estudio retrospectivo de 2010 a 2021 para comprender la naturaleza particular de los fenómenos. RESULTADOS: la tasa de desempleo de la mujer no disminuye al mismo ritmo que la del hombre. La falta de inclusión y oportunidad laboral en el sector formal para la mujer, producto de la discriminación social, se refleja en su alta participación en el sector informal, cuya condición se agudiza cuando existe una combinación de elementos como: sexo, etnia, localidad. CONCLUSIÓN: la brecha de desigualdad por el acceso al empleo entre el hombre y la mujer sigue creciendo, además, los instrumentos para el combate delictivo de  la violencia contra la mujer son insuficientes y no han mitigado los efectos de exclusión.
