Endurance calculation of welded joints in tubbing erector mechanism using digital methods
Authors: Panchenko O , Zabolotnyi K
Published: June 2024

Purpose. To develop and scientifically substantiate a methodology for determining the welded joint endurance during the operation of tubbing erector mechanisms, taking into account the unique conditions of their operation, in particular, under the influence of various types of loads. Methodology. The research uses both theoretical approaches to determining the influence of loads and experimental methods. In particular, the finite element method (FEM) is used when modeling the stress-strain state in welded joints to identify stress concentration points. To assess the endurance of the joints, semi-empirical calculation methods are used, in particular, Hot Spot Stress and Effective Notch Stress, followed by a comparative analysis of the results obtained. Findings. It has been determined that the traditional recommendations for selecting parameters for calculating stresses in technical objects using the Hot Spot Stress method are not always adequate for all scenarios of loading. A modified approach to assessing the endurance of welded joints is proposed, which integrates the Hot Spot Stress and Effective Notch Stress methods and takes into account the specifics of singular stress concentrators. Based on the analysis of the assessment results, greater accuracy in predicting the endurance of welded constructions is ensured. Experimental studies have revealed that the stress values occurring in welds depend on their geometric parameters, which made it possible to specify the criteria for assessing the strength of joints using the modified Hot Spot Stress and the Effective Notch Stress methods. Originality. Since traditional methods for selecting parameters necessary for determining stresses in welded joints using the Hot Spot Stress method are not always appropriate for different types of loads, there is a need to develop a modified combination of the two methods, Hot Spot Stress and Effective Notch Stress. This makes it possible to adapt calculations to the specifics of singular stress concentrators in welded joints, which is the novelty of the research. Practical value. The research results can be used in mechanical engineering to optimize projects for creating welded constructions, increasing their endurance and reliability. The proposed calculation methods make it possible to determine more precisely the values of equivalent stresses in hot spots of welded joints and predict their endurance, taking into account the real production conditions of the equipment operation.

Published: June 2024

Purpose. Analyses of problematic issues of qualification and implementation of criminal liability provisions for the crime provided for in Article 240-1 of the Criminal Code of Ukraine, and elaboration on balanced recommendations for improving the current Criminal Code of Ukraine and the practice of applying its individual provisions. Methodology. A system of methods of scientific knowledge that ensured the achievement of the declared research goal (philosophical (dialectical), statistical, specifically sociological, modeling methods). Findings. Lawmaking and law enforcement problems have been identified, which significantly reduce the preventive and protective potential of Article 240-1 of the Criminal Code of Ukraine, in particular: recognizing illegal actions with amber as criminal ones independent of its value; lack of differentiation of criminal liability for committing the analyzed crime depending on the forms of complicity, as well as poor quality differentiation depending on the value of amber; lack of references to relevant provisions of regulatory legislation in procedural documents; imperfection of the sanctions provided by the considered criminal law prohibition; lack of proper individualization of criminal liability of convicted persons. Originality. The authors were the first in criminal law science to carry out a comprehensive study of the practice of applying Article 240-1 of the Criminal Code of Ukraine, which made it possible to identify issues of qualification and implementation of criminal liability for illegal actions with amber and, based on this, to put forward balanced recommendations for improving the current Criminal Code of Ukraine and the practice of applying its individual provisions on the regulation of liability for illegal actions with amber. Practical value. Based on the results of elaboration on the research piece, specific proposals have been developed which can be considered during further law-making regarding updating relevant provisions of the applicable criminal law and in the course of law enforcement actions. It has been argued that in order to improve the ban under study, it is necessary to strengthen criminal liability regime for the commission of the acts provided for in Part 1 of it in the case of their commission by a group of persons, organized group and on a large scale. It has been justified that the analyzed composition of the crime should be constructed as formal and material. It has been proven that law enforcement bodies should: a) indicate in the relevant procedural documents, firstly, not only the mass of amber, but also its value, secondly, refer to the acts of regulatory legislation, which establish the procedure for mining and circulation of amber; b) pay more attention to the individualization of criminal liability of guilty persons.

A One-Parameter Class of Separable Solutions for An Age-Sex-Structured Population Model with an Infinite Range of Reproductive Ages, A Discrete Set of Offspring, and Maternal Care
Authors: Skakauskas Vladas
Published: June 2024

A mathematical model based on a discrete newborn set is proposed to describe the evolution of a sex-age-structured population, taking into account the temporary pair of sexes, infinite ranges of reproductive age of sexes, and maternal care of offspring. Pair formation is modeled by a weighted harmonic mean type function. The model is based on the concept of density of families composed of mothers with their newborns. All individuals are divided into the pre-reproductive and reproductive age groups. Individuals of the pre-reproductive class are divided into the newborn and teenager groups. Newborns are under maternal care while the teenagers can live without maternal care but cannot mate. Females of the reproductive age group are divided into singles and those who care for their offspring. The model is composed of a coupled system of integro-partial differential equations. Sufficient conditions for the existence of a one-parameter class of separable solutions of this model are found in the case of stationary vital rates.

Published: June 2024

PT X is a manufacturing company operating in the integrated cardboard industry, utilizing various machines, including flexography machines. This study aims to analyze the primary causes of production deficiencies in the flexography process and provide improvement recommendations using the Six Big Losses-based Overall Equipment Effectiveness (OEE) method. The OEE analysis revealed that the average availability ratio is 88.8%, falling short of the world-class standard of 90%. A deeper analysis using the Six Big Losses methodology identified that the primary cause for not achieving the desired availability ratio is the high percentage of setup and adjustment losses, which stands at 7%. To address these issues, several recommendations are proposed. Firstly, conducting comprehensive training for operators on the proper and correct operation of flexography machines is essential. This training will enhance their technical skills and reduce the time lost during setup and adjustments. Secondly, implementing daily briefings for operators before shifts begin, coupled with regular supervision, will ensure consistent adherence to operational standards. Moreover, establishing a routine and time-limited cleaning schedule for machines and work locations will minimize unexpected downtimes due to maintenance issues. Finally, developing and enforcing standardized machine operation protocols will promote discipline among operators, ensuring that all procedures are followed meticulously. These recommendations aim to improve the overall efficiency of flexography machines, thereby increasing the availability ratio to meet or exceed the world-class standard. By addressing the root causes of production inefficiencies, PT X can enhance its operational performance and maintain its competitive edge in the cardboard industry.

PT Wijaya Karya Industri dan Konstruksi has businesses in the fields of Steel, Plastic, Pressing and Casting (PPC) Manufacturing and heavy construction equipment. The PPC factory produces various kinds of manufacturing components, one of which is vehicle spare parts made from metal which are produced using a casting process. One of the products produced using a casting process is Pipe Water Inlet EW010. There are many Pipes Water Inlet EW010 defective products with an average of 52% defective products in July-August 2023. The research was conducted to analyze the sigma value and determine the factors of product defects and the impact of the defects to provide suggestions for product quality improvement. In this research, the method applied is the Six Sigma method and FMEA, by implementing DMAIC (Define, Measure, Analyze, and Control). From this research, the results showed that the most common defects were Leaking, Pen/core, and Porous, namely 89% cumulative. Pipe Water Inlet EW010 products are currently at level 2.44 sigma so corrective action needs to be taken to reach the six-sigma level. By applying the FMEA method, it can be seen that the most significant and most frequently occurring product defects are caused by poor core quality and work method errors. Therefore, the recommended alternative repair solution is to improve the quality of the cores used and improve work methods. The results show an increase in the sigma level value from 2.44 to 2.86 and a decrease in average defects from 52% to 23%.

Published: June 2024

The garment industry is one of the fastest-paced production environments, where speed and accuracy are crucial for meeting global customer demand. Cycle time plays an important role in satisfying the speed factor as it represents the overall time needed to produce a single piece of a product. Maintaining an appropriate cycle time is key to achieving production line balance. This study aims to analyze the cycle time of men's jacket production on a sewing line in an Indonesian garment industry by comparing the actual cycle time with the standard cycle time based on the operation breakdown for each production process step. Four significant discrepancies in actual cycle time were identified, ranging from 16% to 95%, indicating that the actual cycle time was significantly longer than the standard cycle time. The root cause of the highest cycle time was analyzed using Fishbone and 5 Whys analysis to understand the problem from each factor and sub-factor. Six improvement action plans were proposed and implemented, resulting in a 57.81% reduction in actual cycle time, from 127.66 seconds to 53.85 seconds, making it 17.66% faster than the standard cycle time. Furthermore, the total output per hour increased by approximately 216.67%, from 12 pieces to 38 pieces. This result implies that the study successfully identified the root of the problem on the sewing line and managed to increase production output.

Published: June 2024

Objective: To assess inter-observer reliability and reproducibility of CROES, Guy’s and S.T.O.N.E. nephrolithometry scoring systems (NSS). Material and Methods: A total of 128 patients who underwent percutaneous nephrolithotomy (PNL) between January 2019 and January 2021 were included in the study. Calculation of the CROES, S.T.O.N.E, and Guy’s NSSs was made by three independent urologists with different academic levels. These were; a very experienced (>500 PCNL cases) endourologist (Rater 1), a urologist who had just finished (>100 PCNL cases) their urology education (Rater 2) and a 3rd year urology resident who had never performed a PCNL operation (Rater 3). All were blinded to the procedure outcomes. Results: An excellent correlation was found between three raters for Guy and S.T.O.N.E. scoring systems (kappa value 0.810-0.962). However, for the CROES score there is an excellent correlation between Rater 1 and Rater 2, but there were good correlations between Rater 1 vs Rater 3 and Rater 2 vs Rater 3 (kappa values 0.910 and 0.698-0.721 respectively). The highest correlation was between Rater 1 and Rater 2 for Guy score (kappa value 0.962) (Table 3). All intra-class correlations were statistically significant (p<0.001). The highest intra-class correlations were seen for the S.T.O.N.E. score (ICC: 0.980). Conclusion: The present study revealed that all three NSS frequently used in current urology practice have reproducible and reliable results. Additionally, we believe that the application of CROES NSS by more experienced clinicians will be effective in obtaining clearer results.

Arslan'ın doktora tezinin kitaba dönüştürülmesiyle ortaya çıkan bu eser, Arslan'a göre bilim sosyolojisi alanında hazırlık aşaması özelliği taşır. Çünkü ülkemizde bu alanda yazılmış olan ilk eserdir. Öte yandan Arslan, eserinde bilginin nasıl oluşturulduğu ve nasıl kabul gördüğüne yönelik tartışmalara yer vermektedir. Eserin akademinin içinden bir ses olması dolayısıyla, genç araştırmacılar için bir motivasyon kaynağı olabileceği ve özellikle sosyal bilimler alanındaki okuyucular için anlamlı sorgulamalara kapı aralayacağı düşünülmektedir.

Araştırma, ortaöğretimde hafızlık eğitimi alan öğrencilerin teknolojiye yönelik tutumlarını ve tekno-dindarlığa yönelik görüşlerini belirlemek; bu tutumların program türü, cinsiyet, sınıf düzeyi ve yerleşim yerine göre farklılaşıp farklılaşmadığını incelemek amacıyla yapılmıştır. Veri toplama sürecinde ortaöğretim öğrencilerinin teknolojiye yönelik tutumlarını ölçmek amacıyla genel tarama (survey) modeli kullanılmıştır. Çalışma, 2022-2023 eğitim-öğretim yılında hafızlık proje okullarında öğrenim gören toplam 271 öğrenci ile gerçekleştirilmiştir. Veri toplama aracı olarak Yurdugül ve Aşkar tarafından hazırlanan “Öğrencilerin Teknolojiye Yönelik Tutum Ölçeği (ÖTYT)” ve Torun tarafından hazırlanan “Tekno-Dindarlık Ölçeği (TDÖ)” kullanılmıştır. Araştırma verileri dijital ortamda toplanmış ve bilgisayar ortamında çözümlenerek yorumlanmıştır. Verilerin analizinde dağılımın normalliğini test etmek maksadıyla Kolmogorov-Smirnov testi uygulanmıştır. Yapılan normallik testine bakıldığında verilerin bütün analizler açısından normal dağılım gösterdiği görülmüştür. Dağılımın normal olması sebebiyle örneklemin karşılaştırılmasında bağımsız gruplara t testi, ikiden fazla olan örneklemin karşılaştırılmasında tek yönlü varyans analizi tercih edilmiştir. Araştırmada sonuç olarak örgün eğitimle birlikte hafızlık projesinde öğrenim gören öğrencilerin teknolojiye yönelik tutumları ile sınıf düzeyi ve cinsiyet arasında anlamlı fark tespit edilmiştir (p<.0.05). Ancak sınıf düzeyi ve cinsiyet bağımsız değişkenleri bağlamında tekno-dindarlığa dair anlamlı bir fark tespit edilememiştir. (p<0.05). Diğer yandan gerek teknolojiye yönelik tutum gerek tekno-dindarlık bağlamında yerleşim yeri ve program türü açısından da anlamlı bir fark tespit edilememiştir (p<0.05).

6 Şubat Kahramanmaraş merkezli iki büyük deprem sadece 11 ili değil Türkiye’nin tamamını ilgilendiren önemli sosyal bir hadise olarak tarihteki yerini aldı. Önemli iç göç hareketlerine neden olan depremin ardından yaşananlar, afet sosyolojisinin Türkçe literatürde neden daha fazla çalışılması gerektiğini hatırlattı. Ülkemizde uluslararası düzensiz göç çalışmalarının gölgesinde kalan iç göç hareketlerinin ülke içerisinde oluşturduğu hareketliliğin tetkik edilmeye muhtaç durumu, özellikle afet sosyolojisinin göç hareketleri ile birlikte incelenmesi gerekliliği ile birleşince bu çalışmanın üzerinden uzun yıllar geçse de kendisinden sonra gelen çalışmalara rehberlik edeceği gerçeğini ortaya koymaktadır. Çalışma, 6 Şubat Depremlerinin ardından Türkiye içerisinde yaşanan iç göç hareketlerini, afet sosyolojisi bağlamında ve sosyal politikalar ekseninde analiz etmeyi ve durum tespiti yapmayı, gelecekte yaşanması muhtemel benzer afet durumlarında da yapılması gerekenleri aktarmayı amaç edinmektedir. Sonuç itibariyle düşünüldüğünde ise; Türkiye’de deprem sonrası yaşanan iç göç hareketlerinin kısa sürede geri dönüşlere sebep olduğu fakat bu süreç içerisinde toplumun belleğinde önemli kırılmalara da neden olduğu görülmüştür.
Cinderella: The Feminist Tale (A Discourse Analysis of the Story’s Adaptation through Podcast)

Cinderella’s character and feminist ideology are contradictory. The phrase “Cinderella Complex Syndrome,” which refers to women’s dread of independence, supports this idea. Fairy tales are full of beautiful, passive, submissive princesses, as well as bold, independent female constrained by archaic gender stereotypes. They uphold conventional norms about gender roles and value. Fairy tale adaptation is not a new phenomenon; for centuries, people have used it to further their objectives, uphold their cultural standards, and further their ideologies. The construction of feminism in Cinderella rhyme via podcast is the main focus of this study. This rendition carries the feminist ideals while representing an unexpected tale. This study uses discourse analysis methodology, relying on the ideas of liberal feminism and Linda Hutcheon’s theory of adaptation. According to this theory, adaptation encompasses both the process and the final output. It is evident from Cinderella’s podcast that retelling of the narrative is dependent on the story teller’s perception and incorporates a new ideology – liberal feminism, which is associated with the second wave of feminism. This study shows how the liberal feminism ideology in Cinderella’s rhyme is constructed through modifications in the storyline and characterization. This Cinderella portrayal gives more depth that doesn’t match the image of a traditional princess and shows that she can accomplish anything she sets her mind to. This Cinderella adaptation tale shows Cinderella active role that frees herself from her oppressor as the development of liberal feminism in her character. Cinderella’s assertive voice in voicing her demands and desires also supports the liberal feminism idea.

In recent years, the widespread adoption of digital textbooks has revolutionized the way students access educational content. Technology has advanced quickly, and as a result, textbooks are now available to students worldwide in digital form, which has improved their overall academic performance. This modification is acceptable for the sustainable learning program, where students have access to materials from anywhere and at any time and digital textbooks promote online learning. This study intends to examine the variables influencing elementary distance learner students’ intentions to adopt digital textbooks. Structured equation modeling (SEM) was used to evaluate quantitative data from 316 higher education students in Indonesia. According to the findings, students' intentions to use digital books were positively impacted by facilitating condition (Conway & Huffcutt), performance expectancy (PE), self-efficacy (SE), and perceived learning opportunities (PLO). However, attitude, affective, ICT usage habits, effort expectancy, and social influences did not affect students’ intention to use digital textbooks. This research provides important information for the government, decision-makers, and schools on using digital textbooks at the tertiary level in the future.

Today, businesses are operating in a VUCA environment. In the VUCA environment, Occupational Safety and Health (OSH) skills are essential for a business’s viability and sustainability since they safeguard personnel, ensure legal compliance and standards conformance, reduce operational costs, foster productivity, elevate reputation, and exhibit social responsibility. In a VUCA environment, the risk management process acts as a pillar for business viability and sustainability. With effective risk management, businesses can use it to proactively detect and reduce risks, improve adaptation and resilience, guarantee business continuity, make better decisions, and instill confidence among stakeholders. Businesses may negotiate uncertainty, grasp opportunities, and put themselves in a position for long-term success by managing risks properly. Effective risk assessors are essential to the success of risk management because they provide accurate and trustworthy assessments of potential risks. Hence, through this study, it investigates the criticality of OSH risk assessor skills in functioning in the VUCA environment; and identifies the pedagogical preferences for effective risk assessor program. A quantitative research approach is employed for this study, utilising a three (3) parts survey comprising 25 items. The study involved fifty (50) OSH practitioners as the respondents. The Relative Importance Index (RII) results for OSH risk assessor skills in a VUCA environment, assessed on a ten-point Likert scale, are as follows: applied knowledge of the subject matter (0.88), communication skills (0.87); attention to detail (0.87); risk control techniques (0.87); ethical consideration (0.87); risk assessment methodologies (0.86); analytical thinking (0.85); critical thinking (0.85); data analysis (0.84) and adaptability (0.84). Next, respondents conveyed their preferences regarding pedagogical approaches using a ten-point Likert scale. The Relative Importance Index (RII) scores for these approaches are as follows: problem-based learning (0.83); authentic assessment (0.82); inquiry-based learning (0.81); collaborative learning (0.81); technology integration (0.81); experiential learning (0.81); cultivating creativity and innovation (0.81); project-based learning (0.80); multidisciplinary and interdisciplinary approaches (0.80) and metacognitive strategies (0.79).This study contributes to the design of the OSH risk assessor programme for assisting industries in operating in the VUCA environment by helping them to understand the vision, develop situational awareness, make complex situations clear, and generate hypotheses to address potential risks, all of which lead to more informed decision-making, increased resilience, and efficient resource use.
