Authors: Ji Changan , Wang Kang , Wang Qunjing , Chen Quan , Fan Minghao , Xu Bin , Wang Xiaoming , Zhao Wenguang , Xiong Lei 
Published: January 2025

Introduction:
Arc fault has become an increasingly prominent problem affecting the
safe operation of power distribution networks. Research on arc fault detection can effectively reduce
electrical fire accidents caused by arc faults, which is of great significance for ensuring the
safe and reliable operation of power distribution networks.

Methods:
In this paper, an arc fault detection method based on current convolution is proposed for
single-phase AC series arc faults. Firstly, the phase of the measured phase current is acquired
through the phase-locked loop. Then, the measured phase current is convoluted with the standard
sinusoidal signal whose phase is the same as the measured phase current, and the DC component
is obtained by low-pass filtering.

Results:
The occurrence of an arc fault is recognized by detecting the change in the DC component.

Conclusion:
Finally, the simulation results verify that the proposed method can detect the arc
fault quickly and accurately.

Authors: Liu Hongbo , Wu Juncheng , Lin Yuze , Yang Xiaodong 
Published: January 2025

Background:
Inertial navigation is a comprehensive technology involving precision
machinery, computer technology, microelectronics, optics, automatic control, materials, and other
disciplines and fields. Strapdown inertial navigation systems have gradually developed into the
mainstream and direction of inertial navigation systems because of their small size, low cost, simple
structure, and high reliability. The angular rate and acceleration information of the carrier relative
to the inertial space are measured by the inertial measurement unit (IMU), and the instantaneous
velocity and position information of the carrier are automatically calculated by Newton's law
of motion. It has the characteristics of not relying on external information, not radiating energy to
the outside world, not being disturbed, and good concealment. Therefore, it is widely used in aerospace,
aviation, and navigation, especially in the military field.

Objective:
This paper describes the development history of the Strapdown Inertia Navigation System
summarizes the research status of the Strapdown Inertia Navigation System, and looks forward
to its future development direction.

Method:
The key technologies of strapdown inertial navigation systems are investigated, and the
related research on strapdown inertial navigation technology is understood in detail. The hardware
composition and related algorithms of the strapdown inertial navigation system are analyzed in
detail.

Results:
Nowadays, strapdown inertial navigation technology is the mainstream of inertial navigation
technology. Compared with the gimbaled inertial navigation system technology, the
strapdown inertial navigation system has higher precision, smaller volume, and lower cost. At present,
the initial alignment technology, error compensation technology, navigation algorithm technology,
and inertial device technology of strapdown inertial navigation technology have made full
development.

Conclusion:
With the development of initial alignment technology, error compensation technology,
navigation algorithm technology, and inertial device technology, the accuracy, response speed
and anti-interference ability of strapdown inertial navigation technology have been significantly
improved. The development of strapdown inertial navigation is closely related to the gyroscope
technology which belongs to inertial device technology. The strapdown inertial navigation system
based on optical gyroscopes such as laser gyroscopes and fibre optic gyroscopes is mature, and the
MEMS strapdown inertial navigation system has a wide application prospect compared with the
optical gyroscope strapdown inertial navigation system.
Research Progress in Pre-Stage Deflection Jet Tube Type Electro-Hydraulic Servo Valve
Authors: LI Jianying , Chen Wanting , Guo Qi 
Published: January 2025

Background:
The pre-stage deflection is a key aspect of the deflector jet tube electrohydraulic
servo valve, and its performance not only affects the pressure gain, flow gain, and other
important parameters of the servo valve, but also affects the dynamic and static characteristics of
the servo valve and electro-hydraulic servo system.

Objective:
This paper aimed to outline the working principle of the pre-stage deflector jet tube
type electro-hydraulic servo valve, and review and analyze its research performance development
in five aspects.

Method:
The research progress in the key indexes of servo valve performance at different stages,
the mechanism and phenomenon of the erosion and wear of the pre-stage, the mechanism and
characteristics of the pre-stage cavitation, the structural improvement and parameter optimization
of the pre-stage, as well as the pre-stage drive mode, has been summarized.

Results:
It has been found that although a large number of scholars at home and abroad have improved
the structure and driving mode of the front stage of the deflecting jet tubular electrohydraulic
servo valve and optimized the parameters to improve the performance of the deflecting
jet tubular electro-hydraulic servo valve, the internal flow field of the front stage is complex,
prone to erosion and cavitation and many complex phenomena, and there are still many aspects to
be improved and innovated.

Conclusion:
This paper has thus summarized the defects of the front-end stage, and put forward
three future innovations of miniaturization, intelligence, and multifunction, to contribute innovative
ideas to the design of the front-end stage of the deflection jet pipe electro-hydraulic servo
valve in the future.

Published: January 2025

Objective:
This review examines the efficacy of psychological interventions
in the management of Irritable Bowel Syndrome (IBS).

Methods:
In the current study, a comprehensive analysis of the existing literature,
covering case studies and clinical trials, compiled from Google Scholar,
Sci-Hub, and PubMed, was performed. The research focused on the complex interplay
between psychological factors and irritable bowel syndrome (IBS), particularly
the ways in which mental and emotional states can impact IBS symptoms
and the effects of behavioral therapy on IBS management.

Results:
The efficacy of psychological therapies in addressing irritable bowel
syndrome (IBS) has proven effective. Cognitive Behavioral Therapy (CBT)
treats pain perception and gastrointestinal symptoms, whereas gut-directed hypnotherapy
is known for lowering symptoms and enhancing quality of life. Mindfulness-
based stress reduction and relaxation practices are effective for stress management,
but their availability is restricted. Personalized treatment strategies
tailored to individual requirements are vital for enhancing the advantages of these
therapies in IBS management.

Conclusion:
Psychological interventions provide a valuable and effective approach
to managing IBS. CBT, gut-directed hypnotherapy, and MBSR have
been shown to significantly improve symptoms and quality of life. Future research
should focus on improving these therapies to better address individual
symptoms and brain-gut connections. Incorporating neurological and neurophysiological
approaches may improve understanding and lead to more tailored
treatments. Expanding accessibility and encouraging collaboration between
healthcare providers and mental health specialists will be vital for optimizing
IBS management and improving patient outcomes.

Published: January 2025

The aim of this research were to analyze the RPM effect on the Petokong Type TEP 1 cutting capacity. The tools used include TEP-1 Type Cassava Stem Cutter, tachometer, stopwatch, 1000 ml measuring cylinder, 3.4 and 6 inch pulleys. The amount of bait used in this study was 2, 3, 4 cassava stalks. Revolutions per Minute (RPM) modification is done by using different pulley diameters. Pulleys with a diameter of 3 inches produce 3500 RPM, a diameter of 4 inches produces 2625 RPM, and a diameter of 6 inches produces 1750 RPM. Parameters observed in this study included working capacity, fuel consumption, and seed size uniformity. The best working capacity is owned by the B2R1 treatment combination of 9,900 seedlings/hour with the feed amount of 3 cassava stalks and 3500 RPM, while the lowest capacity is 6,000 seeds/hour produced in the B1R3 treatment with the feed amount of 2 cassava stems and 1750 RPM. Measuring fuel consumption is necessary using methods that are accurate and of long duration. In this study, the measurement of fuel consumption only lasted for 2 minutes using the method of adding fuel volume. This will cause a high error in the calculation. The use of Petokong produces a uniformity of above 95% which causes low seedling damage due to cutting.Keywords: Cassava Seeds, Cultivation of cassava, Lampung, Cutting machine, Pulley

Preparation of cassava seeds is usually done manually so it takes a relatively long time. TEP-1 type cassava stem cutter (Petokong) is a solution to meet the needs of cassava seeds in large quantities and quickly. This study aims to determine the performance of TEP-1 type Petokong and to compare it with manual cutting using a machete and saw, as well as to find out the cuttings of the seeds produced. The research was conducted in May 2019, at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The research was conducted by cutting cassava seeds using 3 different cutting tools, namely machetes, saws and TEP-1 type petokong. The research parameters consisted of cutting capacity, seedling size uniformity, seedling damage and growth test. The results showed that the highest cutting capacity of cassava stems was TEP-1 type petokong which produced 9720 seeds/hour while cutting using a saw produced 3600 seeds/hour and the lowest was cutting using a machete, as many as 1800 seeds/hour. The uniformity of cassava seeds cut using a TEP-1 type petokong is 99%, while cutting using a saw is 95%, and using a machete is 40%. The lowest percentage of damage to seedlings resulting from cutting was using TEP-1 type petokong which was 2%, damage to seedlings using saw was 10%, and using machetes was 20%. The results of testing the growth of seedlings up to the roots explained that cutting using a TEP-1 type of petokong had perfect and spreading root growth, cutting with a saw showed uneven root growth and cutting using a machete the root growth only occurred on several sides of the cassava seedlings. Keywords: Capacity, Cassava Stems, Cutting Tools.

Climate classification in Indonesia is needed to simplify climates, which vary greatly in number. The classification system that is often used in Indonesia is the Schmidt-Ferguson and Oldeman classification. The location of this research is Central Lampung Regency. In determining the climate type of Central Lampung Regency, there are 2 levels of the Schmidt-Ferguson climate suitability category for rice. The Sangat Sesuai (SS) category was 68,087.22 ha from 45.29% of the total ricefield area and for the Sesuai (S) category it was 82,235.04 ha from 54.71% of the total ricefield area. In Oldeman's climate suitability for rice, there are 2 levels of categories. The area for the Sangat Sesuai (SS) is 146,097.48 ha from 97.17% of the total ricefield area and for the Sesuai (S) category it is 4,252.54 ha from 2.83% of the total ricefield area. Rice suitability analysis was carried out to obtain a rice agro-climatic zone based on a ricefield use map and 5 regional limiting factors, namely: 1) Oldeman climate classification, 2) Schmidt-Ferguson climate classification, 3) Temperature, 4) Humidity, and 5) Slope. These 5 factors will be overlaid using Quantum GIS. The result of this analysis is that Central Lampung Regency is dominated by the Sesuai (S) category which is good for agricultural activities, especially rice plants. In the Central Lampung Regency, there are 3 categories of suitability for rice plants. In the Sangat Sesuai (SS) category of 63,780.33 ha of 42.43% of the total area of ricefields, for the Sesuai (S) category of 86,157.08 ha of 57,31% of the total area of ricefield, and in the Tidak Sesuai (TS) category of 389.00 ha of 0.26% of the total area of ricefield.

On regular power fuzzy graphs
Authors: Bharathi T. , Paulin S. Shiny , Sherlin M. Jeba 
Published: January 2025

Abstract
In this paper, we define the notion of regular power fuzzy graph (RPFG), as a combination of regular properties and power fuzzy graphs. We also define totally regular power fuzzy graph as a special case of RPFG. A comparative study between regular and totally regular power fuzzy graphs is investigated. It is also proved that any power fuzzy graph containing a pendant vertex can be neither regular nor totally regular. A necessary condition for a total power fuzzy graph to be perfectly regular is that the vertex and edge membership functions are constants.

Authors: Nathania D.P Salsabilla , Sujibto B.J. , Puspitasari Intan 
Published: January 2025

The phenomenon of quiet quitting has been recognized as a growing trend in the workplace, particularly among recent graduates post-COVID-19 pandemic. It reflects a deliberate strategy by young workers to resist excessive workloads and address organizational neglect of work-life balance. This study employs a qualitative approach, focusing on five informants who are recent university graduates working in Yogyakarta's informal sector. In-depth interviews were conducted to understand their experiences and strategies in practicing quiet quitting. The findings reveal that quiet quitting emerges as a coping mechanism against exploitative work demands, involving strategies such as rejecting additional tasks outside working hours, clearly separating work from personal life, and negotiating a balance between professional obligations and personal well-being. These practices indicate resistance to exploitative workplace norms and highlight a broader effort to establish sustainable work-life dynamics. The study underscores quiet quitting as a covert resistance strategy that is intricately tied to maintaining well-being and balance.AbstrakFenomena quiet quitting telah menjadi tren yang semakin berkembang di dunia kerja, terutama di kalangan fresh graduate pasca-pandemi COVID-19. Praktik ini menunjukkan adanya strategi yang disengaja oleh pekerja muda untuk menolak beban kerja berlebihan serta kurangnya perhatian organisasi terhadap keseimbangan antara kehidupan kerja dan pribadi. Penelitian ini menggunakan pendekatan kualitatif dengan melibatkan lima informan yang merupakan lulusan perguruan tinggi di Yogyakarta dan bekerja di sektor informal. Wawancara mendalam dilakukan untuk memahami pengalaman mereka dan strategi yang diterapkan dalam praktik quiet quitting. Temuan penelitian menunjukkan bahwa quiet quitting muncul sebagai mekanisme penyesuaian terhadap tuntutan kerja yang eksploitatif, dengan strategi seperti menolak tugas tambahan di luar jam kerja, memisahkan secara tegas kehidupan pribadi dari pekerjaan, serta menegosiasikan keseimbangan antara tanggung jawab profesional dan kesejahteraan pribadi. Praktik ini menunjukkan adanya bentuk resistensi terhadap norma kerja yang eksploitatif sekaligus menekankan perlunya upaya lebih luas untuk menciptakan dinamika kerja yang berkelanjutan. Penelitian ini menegaskan bahwa quiet quitting merupakan strategi resistensi terselubung yang terkait erat dengan upaya menjaga kesejahteraan dan keseimbangan hidup.

Authors: Argenta Thaís Salvador , Borin Maria Luísa Batista , Busato Jader Galba , Amorim Ariuska Karla Barbosa 
Published: January 2025

Objective: This research aimed to carry out a bibliographical survey through bibliometrics to know the state of the art on the anaerobic treatment of leachate from composting with nanoparticles.

Theoretical Framework: Composting is one kind of waste treatment and its process generates an effluent named leachate. The anaerobic digestion can treat this material and generating biogas for energy use. Additionally, the use of nanoparticles appears as a technological tool capable of improving the production of biogas and the percentage of methane.

Method: The tool used to produce this research was bibliometric analysis. Searches were performed in the Web of Science and Scopus databases in September 2024 with a focus on anaerobic digestion of compost leachate. No search period was defined. The strategy of using both databases was to expand the amount of work related to the topic.

Results and Discussion: The first work indexed in both databases is from 2011. From 2011 to September 2024, 32 articles related to the topic were published with the participation of 18 countries, 153 authors and 70 institutions. The journal that accumulated the highest number of publications was Waste Management.

Research Implications: The implication of this research is to provide general information about the researches being developed and thus to identify scientific gaps. From this overview, the research field can be better studied and new publications will emerge.

Originality/Value: This research showed that the study of anaerobic digestion of composting leachate with nanoparticles is quite incipient and promising, as few articles on the subject have been reported. This is a scientific gap.

Authors: Pereira Victor Vinhal , Lyra Marília Regina Costa Castro , Maciel Netto André , Rodrigues Sofia Suely Ferreira Brandão 
Published: January 2025

Objective: This study aimed to characterize biological sludge residue from an industrial effluent treatment plant to assess the legal framework for its application in soil.

Theoretical Framework: Biological sludge generated during the industrial effluent treatment process constitutes one of the main residues of a refinery. When treated properly and in accordance with current standards, it has potential for use in agriculture and forestry, whether in its natural form, organic compost, blended with other residue or biochar.

Method: The residue was sampled and analyzed according to the aspects recommended by CONAMA Resolution No. 498/2020, namely: agronomic potential, reduction of vector attractiveness; chemical substances and microbiological quality.

Results and Discussion: The biological sludge did not meet the criteria for reducing vector attractiveness and barium concentration for the disposal of the residue in its natural form in soil. However, its agronomic potential and absence of organic chemical substances and pathogenic organisms allow investment in research aimed at its agricultural use in the form of organic compost, blended with other waste or even as biochar.

Research Implications: For industries that use the activated sludge system to treat their effluents, the disposal of biological sludge is a major challenge and its use in agriculture or forestry has been growing in recent years throughout the world.

Originality/Value: The disposal of biological sludge in natura is justified not only by taking advantage of the benefits of the components present in the sludge, but also because it is a low-cost alternative when compared to other forms of disposal.

Published: January 2025

Objective: The present study aimed to understand the perception of mental health in school students in the department of Córdoba, Colombia, in order to identify the social representations and motivations towards mental health care in this population.

Theoretical framework: The research is based on the health beliefs model, exploring categories such as generic perception of mental health, perceived susceptibility, perceived severity, signals for action, perceived barriers, perceived benefits and motivation.

Method: A hermeneutic-phenomenological qualitative approach was used. Thirty-five young people between 15 and 19 years of age participated and were interviewed to analyze their perspectives and experiences related to mental health.

Results and Discussion: The results showed a dichotomy in the understanding of the term “mental health”, associating it with both wellbeing and pathology. In addition, bonding experience played a relevant role in the categories of perceived susceptibility and cues to action. Well-being was identified as the main motivation for accessing mental health services. These findings highlight the need for comprehensive and timely care, especially in the post-confinement context of the COVID-19 pandemic.

Research Implications: This study underscores the importance of designing social-emotional interventions tailored to the needs of schooled adolescents, promoting strategies that favor early access and motivation towards mental health care.

Originality/Value: The research provides a contextualized analysis of the beliefs and experiences of young people regarding mental health, contributing to the design of policies and programs aimed at this population in post-pandemic contexts.
