Published: June 2023

K-Pop fandom members participate in various pro-social activities, including donations, campaigns, and volunteering. Any form of pro-social behavior performed by the K-Pop fandom is related to its social identity as part of the fandom. This study aimed to analyze the correlation between K-Pop fan social identity and pro-social behavior. The study involved 145 individuals recruited through purposive sampling with the criteria such as aged 18–40 years and members of at least one K-Pop fandom. The data analysis revealed that social identity had a significant positive correlation with pro-social behavior and the direction of the relationship between the two variables was moderately strong. In other words, higher levels of social identity within the K-Pop fandom were associated with increased engagement in pro-social behaviors. Meanwhile, lower levels of social identity corresponded to reduced pro-social behavior.KATA KUNCI:Anggota fandom K-Pop; K Pop; perilaku prososial; identitas sosialABSTRAKAnggota fandom K-Pop berpartisipasi dalam berbagai kegiatan pro-sosial, termasuk donasi, kampanye, dan menjadi sukarelawan.

Published: June 2023

The research aims to analyze the effect of the Contextual Teaching and Learning (CTL) approach on creative thinking skills and learning outcomes and to describe the implementation of mathematics learning using the Contextual Teaching and Learning approach for class VI students at SDN 2 Ketapang Banyuwangi on the material Circumference and Area of a Circle. A mixed method was used in this research. The population in this research were all of the sixth-grade students for the 2021/2022 academic year, with a total of 54 students. The samples in this research were 23 students in the control class and 23 students in the experimental class, respectively, where the sampling technique used the Yamane formula. Statistical analysis used comparative analysis (t-test) and the N-gain test. The results showed: 1) the post-test t-test results between the control and experimental classes with a t-value of 4.791 (p-value = 0.000) and the t-test results differed between the post-test and pre-test scores between the control and experimental classes with the t-count value of 5.368 (p-value = 0.000). Both p-values are less than α (0.05), which means that the CTL approach influences students' creative thinking skills. 2) the post-test t-test results between the control and experimental classes with a t-count value of 2.136 (p-value = 0.038), the t-test results are the difference between the post-test and pre-test values between the control and experimental classes with a t-count value of 3.038 (p-value = 0.004). Both p-values are less than α (0.05), which means that the CTL approach has an effect on students Mathematics learning outcomes. Thus, the CTL approach has an effect on creative thinking skills and the mathematics learning outcomes of grade VI students on the circumference and area of a circle.

Published: June 2023

The frequency of purulent arthritis of the sternoclavicular joint is less than 1 % of all joint infections. As a rule, the cause is the hematogenous spread of a generalized infection or trauma.Material and methods. The result of treatment of 24 patients (18 men, 6 women, mean age 38.4 years) with purulent arthritis of the sternoclavicular joints in the period from January 1, 2012 to December 30, 2022 is presented. The causes, clinical manifestations, options for surgical intervention and treatment outcome.Results. Most patients (20 people) complained of pain and tissue swelling in the area of the affected joint. In 4 patients, the main symptom was pain and limited mobility of the arm on the side of inflammation, while no external manifestations of the infectious process were detected. The main laboratory indicators of the inflammatory process were leukocytosis (mean (12 ± 1.6)·109/l) and an increase in CRP from 4 to 86 mg/l (mean 22 ± 4.2 mg/l). 50 % of patients had type 2 diabetes. In 14 patients, in addition to the destroyed sternoclavicular joint, there was damage to the rib/ribs, sternum. In 5 patients, the infectious process was bilateral. Each patient underwent resection of the clavicle and sternum together with the sternoclavicular joint; if the ribs were affected, they were resected. Intraoperative complication was registered in 1 case – erosive bleeding from the right subclavian vein. All patients were treated in two stages. The main pathogen was Staphilococcus aureus. After cleansing the wound, it was closed with local or displaced tissues. Histological examination of removed macropreparations in 18 patients revealed signs of acute osteomyelitis. 5 patients needed intensive care, of which 4 patients died: from progressive sepsis against the background of multiple organ failure and from progressive heart failure against the background of pulmonary edema. Recurrence of the infectious process in the surgical area occurred in 1 patient.Conclusions. Purulent arthritis of the sternoclavicular joint is not an independent disease. Hematogenous damage to this area is associated with a decrease in immunity and the development of a generalized infection. Treatment should be complex, aimed at surgical removal of pathologically altered structures and tissues, as well as intensive therapy to compensate for organ dysfunctions.
VERTICAL MOTION OF MINIATURE WALKING ROBOTS. STATE OF THE PROBLEM REVIEW
Authors: Platov Illia , Pavlovskyi Oleksii 
Published: June 2023

The article reviews the state of the art of developing miniature walking robots for vertical movement due to friction forces between limbs and surface. In particular, special attention is paid to miniature walking robots - hexapods, as they have good stability and cross-country ability compared to other types of robots, both wheeled and tracked. Unlike other types of robots, hexapods can be fully autonomous. This makes them a potentially versatile tool for solving a variety of tasks in different areas, such as: 1) rescue operations - hexapods can penetrate destroyed buildings to assess the condition under the rubble, explore underwater spaces, and generally move in places where there is not enough space for movement and complex maneuvers; 2) military use - hexapods can clear mines, be used for reconnaissance or surveying, while saving lives due to the possibility of complete autonomy; 3) industrial applications - due to their maneuverability and cross-country ability, hexapod robots can become indispensable in quarries and construction sites where there are slopes, mountainous terrain, and generally where wheeled or tracked robots cannot easily move; 4) speleology - search and exploration of minerals inside caves, mines, etc; 5) accident response, in particular, in the nuclear power industry.
Despite the long history of development and significant progress in this area, thanks to which many design solutions and modernizations are already known, the problem of vertical movement of small hexapod robots due to friction forces still remains unsolved.
Existing developments are usually aimed at moving on surfaces by imitating the limbs of biological creatures (insects, animals, etc.), which allows robots to climb upwards thanks to an adhesive substance, grip the surface with mechanical claws, etc. Magnet and suction cup designs have also been known for a long time, but this solution requires a very powerful power source and is not universal.
Therefore, one of the most promising areas of research is the vertical movement of hexapod robots due to friction forces between the limbs and the surface, since the robot remains autonomous and does not require special equipment and additional communication with a power source (compressor, etc.), and, more importantly, is able to move both on horizontal and vertical surfaces.
At the moment, there are several examples of successful use of hexapods for vertical movement, but the review of works has shown that the problem of vertical movement of miniature hexapod robots remains relevant and requires further research and development. Existing achievements in this area give us hope that in the future we will demonstrate effective solutions to this problem and the widespread use of hexapods in various industries and science.

The article presents the results of a study of the homogeneity of rectangular optical radiation fluxes for different versions of the initial sections of the light guide nozzles. When conducting a significant part of laser exposure in medicine, pathological areas of biological tissue or their projections located on the surface of the body are covered with light spots with contours, as a rule, in the form of flat geometric shapes.
The variability of the implementation of light spots in shape (circle, square, rectangle, triangle, rhombus, etc.) and linear dimensions of the cross section allows you to select the shape and size of the light spot, covering a specific pathological surface with minimal capture of intact tissues. At the same time, regardless of the shape and linear dimensions, the light spots should be as uniform as possible. To date, of particular interest is the provision of optical uniformity of rectangular light spots.
Firstly, similar forms of spots are widely used under the influence of laser medicine. Secondly, in the original optical stages of laser equipment and the light guides connected to them, first of all, optical fibers of a cylindrical shape with a rounded cross section of the optical flow at the output are used. The purpose of this work is to optimize the parameters of light guide nozzles of medical laser equipment with rectangular output optical radiation fluxes by evaluating the uniformity of the power density distribution for various options for the output sections of the nozzles. In the work, optical flows at the output of three versions of the distal sections of light guides were studied. The light guides were formed by optical fibers, including the use of microlenses at the output ends, and were apertured by channel optical waveguides in the form of rectangular parallelepipeds.
The experimental results obtained at the stage of physical modeling show the promise of using spherical micro-optical elements at the initial ends of optical fibers in combination with rectangular apertures in the form of channel optical waves to obtain rectangular light spots with a high level of optical homogeneity.

Optimized Engineering and Drilling Practices Help Break Record for Extended-Reach Well
Authors: Carpenter Chris 
Published: June 2023

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 204550, “Breaking ERD Records With Optimized Engineering and Practices: Making the Impossible Possible,” by Hussien Alzaki, SPE, Saudi Aramco; Nadhir Rahmani, Schlumberger; and Matthew Carr, K&M Technology Group. The paper has not been peer reviewed.

_
The complete paper describes preplanning, execution, and results of extended-reach drilling (ERD) with a large-bore design of 12¼ in. as the main stepout section and deploying 9⅝-in. casing on a shallow true vertical depth (TVD) of 4,200 ft. Progressive increase of ERD ratio and complexity from one well to the next was planned and executed until a record-breaking well had been achieved, deploying 8 km of 9⅝-in. casing with a 5.4 ERD ratio at 26,179 ft total depth (TD) horizontally all the way.

Planning Consideration and Risk Assessment
The presented ERD campaign was unusual because of its combined ERD ratio and very shallow TVD for the long horizontal sections. In addition to the obligation to reach the targeted formation in a 12¼-in. hole, complex challenges were addressed, such as the obligation to kick off and drill large holes (12¼-in. horizontal hole section and 9⅝-in. casing) up to a 5.4:1 ERD ratio at 4,200 ft (approximately 1,300 m) TVD.
The solution involved implementation of technically modeled engineered solutions that were verified during execution. Operational procedures included the following:
- Proper planning and execution of well profiles to ensure optimal placement in a specific formation and minimum side force
- Drilling and tripping procedures to ensure the lowest friction factor (FF) and allow drilling to TD with a limited rig capability
- Engineered solutions for casing-running technologies, which involved rotation and conventional running and flotation
Following risk assessment and the multiple peer reviews made for the subject well, a drilling plan was established that addressed the anticipated main limitations, which included the following:
- Bottomhole assembly (BHA) and drillstring design to allow reaching TD within optimal rig capacities
- Bit selection to reduce the number of
- runs needed to two (three maximum if a contingency were to be considered)
- Total dissolved solids (TDS) torque-limit management (30,000 lbf-ft at 180 rev/min)
- A rig-pumping pressure limit of 4,600 psi
- Hole-cleaning and FF management to prepare for deployment of 9⅝-in. casing
Is the soil dry density important when using TDR?
Authors: Technion Shay Nachum 
Published: June 2023

Abstract

The use of Time Domain Reflectometry (TDR) to monitor soil water content at either field or laboratory scales is highly common. Regarding the soil bulk density effect on the TDR application, three main approaches are found in the literature: [1] Ignore the density issue and use calibration to a evaluate the water content regardless of the density. This approach is early and basic - yet common. [2] Include soil density in the calibration equation and use empirical calibration for the water content as a function of both the TDR output and soil density. In this approach, the soil density should be provided from a outsource. [3] Calibrate the soil dry density from the TDR waveform. In this case both water content and dry density are determined from the TDR analysis. In cases where the dry density is not available, in order to use TDR for water content measurement, a decision has to be made whether to address the density issue, despite it is requires resources, or not. This paper reviews this issue and validates the density effect using an efficient TDR calibration methodology. A calibration scheme which controls dry density of the specimen has been developed and applied. The methodology creates continuous calibration curves over a range of volumetric water content from a single test specimen. This paper presents a unique examination of the ASTM D6780 standard.
Transport of Bisphenol A, Bisphenol S and three Bisphenol F isomers in saturated soils

Published: June 2023

Abstract
With the limitation of the use of bisphenol A (BPA), the production of its substitutes, bisphenol S (BPS) and bisphenol F (4,4’-BPF) is increasing. Understanding the fate and transport of BPA and its substitutes in porous media can help reduce their risk of contaminating soil and groundwater systems. In this study, column and batch adsorption experiments were performed with 14C-labeled bisphenol analogs and combined with mathematical models to investigate the interaction of BPA, BPS, 4,4’-BPF, 2,2’-BPF and 2,4’-BPF with four standard soils with different soil organic matter (SOM) contents. The results show that the transport capacity of BPS and 4,4’-BPF in the saturated soils is significantly stronger than that of BPA. Meanwhile, the mobility of the three isomers of bisphenol F (2,2’-BPF, 2,4’-BPF and 4,4’-BPF) showed some variability in saturated soils with high SOM content. The two-site kinetic retention mode was applied to simulate and interpret experimental data, and model simulations described the interactions between the bisphenol analogs and soil very well. The fitting results show that SOM provides more adsorption sites for bisphenol analogs and these adsorption sites may be irreversible adsorption sites. For the different mobility of bisphenol analogs, hydrophobicity is the main factor leading to the difference in adsorption affinity between BPA, BPS, 4,4’-BPF and soil. The main factor leading to the difference of adsorption affinity between 4,4’-BPF and its isomers (2,2’-BPF and 2,4’-BPF) and soil may be hydrogen bonding force. In addition, the results of this study show that the relatively high mobility of BPA substitutes BPS and 4,4’-BPF may pose a significant risk to groundwater quality, so 4,4’-BPF and BPS may not be environmentally friendly alternatives to BPA. In addition, as by-products of 4,4’-BPF production, 2,2’-BPF and 2,4’-BPF have high mobility in soil and may pose a more significant threat to groundwater than 4,4’-BPF.

Abstract
Logistics and transportation industry is not only a major energy consumer, but also a major carbon emitter. Developing green logistics is the only way for the sustainable development of logistics industry. One of the main factors of environmental pollution is caused by carbon emissions in the process of vehicle transportation, and carbon emissions of vehicle transportation is closely related to routing, time-dependent speed and the slope of road. Therefore, vehicle routing problem with time windows considering carbon emissions is presented in this paper. a mixed integer programming model is built to describe the carbon emission optimization problem under the constraint of time windows. In this programming model, the high-granularity predictive speeds are used to compute carbon emissions. And to solve this problem, a hybrid genetic algorithm with adaptive variable neighborhood search method is presented. A case study with the logistics and traffic data in Jingzhou, China is validated, and the results shows that the effectiveness of the proposed model and algorithm.

Abstract

The Kagome lattice, naturally encompassing Dirac fermions, flat bands, and van Hove singularities, tends to intertwine exotic electronic states. Revealing the characteristics of its Fermi surface will help on clarifying the nature of the complex quantum phenomena in kagome material. Here we report the Fermi surface properties of the new kagome superconductor CsTi3Bi5 by the de Haas–van Alphen oscillations. The observed oscillations are clear and consist of six principal frequencies ranging from 214 T to 1013 T. The angular dependence of the frequency implies a quasi-two-dimensional electronic structure. In addition, the Berry phase corresponding to 281 T, determined by the Landau level fan diagram method and full Lifshitz-Kosevich formula fitting, yields a value close to π, which indicates a band structure with nontrivial topological property. These results underscore the potential of CsTi3Bi5 as a promising new platform to explore the interplay between topological order, electronic nematicity, and superconductivity.
