Authors: Hassan Mehmood Ul
Published: March 2023

The current study aimed to find out English as a foreign language (EFL) students’ beliefs regarding the usefulness of corrective feedback (CF) in a cooperative learning (CL) environment. This study was a qualitative research design in which a narrative approach was used. The data were collected using interview questions as the research instrument. The researchers had a close observation, prepared notes, and made a record of interview responses from each student to explore and understand their beliefs towards CF provided by the instructors in the CL environment. The findings of this qualitative study revealed that EFL teachers get motivation and inspiration from EFL learners to give a suitable CL environment to second language learners which made the provided CF more effective. In the CL environment, the results indicate that EFL learners realised that they can find solutions to their problems in CL, and in their interviews, they stated that they would not be able to find solutions to their errors individually.

Diagnosis Method of Lubrication Failure by Coolant Immersion for a CNC Lathe Spindle
Authors: Takasugi Keigo , Suzuki Naohiko , Kaneko Yoshiyuki , Asakawa Naoki
Published: March 2023

As a result of the development of network technologies, diagnosis techniques that can collect machine states continuously and prognostic health management (PHM) are available in the factory. PHM technology is also beginning to be implemented in the machine tool field. However, few studies have described causality between feature values, including vibration and acoustic emission data, collected by machine and physical phenomena of failures under the actual use of machine tools. In the present paper, a PHM system of lubrication failure of bearings in CNC lathe spindles is developed. An acceleration sensor is used to collect machine states, and statistical feature parameters that characterize the lubrication failure are extracted from the obtained vibration data. Moreover, in order to clarify the cause-effect relation between the extracted feature parameters and physical phenomena of lubrication failure, several analyses using surface roughness measurement, residual stress measurement, and grease consistency measurement are conducted.

Published: March 2023

Process planning is well known as the key toward achieving highly efficient machining. However, it is difficult to standardize machining skills for process planning, which depend heavily on skilled operators. Hence, in a previous study, a computer aided process planning (CAPP) system using machine learning is developed to determine the operation parameters for finish machining of dies and molds. On the other hand, in rough machining, it is assumed that some machining operations are conducted sequentially using a respective tool according to the workpiece shape, which induces a much higher complexity in process planning. Therefore, in this study, machine learning is adopted to determine operation parameters for rough machining. The developed CAPP system converts the removal volume into a voxel model and infers a machining operation for each voxel. The inferred machining operation is visualized using different colors and identified corresponding to the voxel. Finally, the removal volume is classified using three different machining operations. However, machine learning is said to have a critical problem in that it is difficult to understand the reasons for the inferred results. Hence, it is necessary for the CAPP system to demonstrate the certainty level of the determined operation parameters. Thus, this study proposes a method for calculating the degree of certainty. If an artificial neural network is trained sufficiently, similar inferred results would always be obtained. Consequently, by using the Monte Carlo dropout to delete weights at random, the certainty level is defined as the variance of the inferred results. To verify the usefulness of the CAPP system, a case study is conducted by assuming rough machining of dies and molds. The results confirm that the machining operations are inferred with high accuracy, and the proposed method is effective for evaluating the certainty of the inferred results.
Augmented Reality-Based System for Skill Transfer of Workpiece Fixturing in Turning Operations
Authors: Nishida Koji , Itoh Masatoshi , Nakamoto Keiichi
Published: March 2023

For machining operations, preparation work called a “setting operation” is always required in advance. The setting operation, which affects the lead time and machining accuracy, strongly depends on the skill level of the operator. Therefore, to improve the quality of machining operations, skill transfer is necessary by extracting and generalizing the skills related to the setting operation. In addition, a variety of accidents often occur during the setting operation. This can lead to machine tool failure or a serious incident involving the operator. Thus, skill transfer to an unskilled operator is also important for work safety. On the other hand, augmented reality (AR) is a promising human-computer interaction technology to support skill transfer at the manufacturing site. An AR technology generally overlays virtual images on the real-world environment. In this study, an AR-based system is developed to demonstrate a recommended workpiece fixturing method in turning operations for assisting unskilled operators as the first step of skill transfer. In turning operations, two types of fixturing are usually assumed: outer diameter clamping and inner diameter clamping. The dimensions of the targeted product shape are detected, and the workpiece shape is obtained. The removal volume to be machined is calculated as the difference between the targeted product shape and workpiece shape. The fixturing method is determined to avoid contact between the removal volume and the assumed jaw. The results of a case study show that the developed AR-based system is effective for skill transfer of workpiece fixturing by demonstrating the recommended fixturing method using skills acquired from operators.
Feasibility Study of Laser-Assisted Incremental Forming for Carbon Fiber Reinforced Thermo Plastic Based on 3D-CAD Data
Authors: Tanaka Hidetake , Yamada Kippei , Ikari Tatsuki
Published: March 2023

A three-dimensional (3D) printer can be used to form various shapes in a single process. However, shell shape formation is difficult because of the low adhesion strength between the layers in 3D printing, and sufficient stiffness cannot be maintained. Therefore, the authors focused on laser-assisted incremental forming, which enables the formation of shell shapes from sheet materials, and used carbon fiber reinforced thermo plastic (CFRTP) for the samples. In the study, a laser-assist incremental forming system based on 3D computer-aided design (CAD) data was developed. The system comprises computer-aided manufacturing (CAM) system, which generates a tool path based on CAD data and evaluates the formability between the CAD data and 3D-scanned data, including alignment compensation. The feasibility of the developed system was demonstrated through a set of forming experiments.

Published: March 2023

Efficient hybrid joining methods are required for joining metals and plastics in the automobile and airplane industries. Injection molded direct joining (IMDJ) is a direct joining technique that uses metal pretreatment and injection molding of plastic to form joints without using any additional parts. This joining technique has attracted attention from industries for its advantages of high efficiency and low cost in mass production. Blast-assisted IMDJ, an IMDJ technique that employs blasting as the metal pretreatment, has become suitable for the industry because metal pretreatment can be performed during the formation of the metal surface structure without chemicals. To satisfy industry standards, the blast-assisted IMDJ technique needs to be optimized under blasting conditions to improve joining performance. The number of parameters and their interactions make this problem difficult to solve using conventional control variable methods. We propose applying statistical and artificial intelligence analyses to address this problem. We used multiple linear regression and back propagation neural networks to analyze the experimental data. The results elucidated the relationship between the blasting conditions and joining strength. According to the machine learning predicted results, the best joining strength in blast-assisted IMDJ reached 22.3 MPa under optimized blasting conditions. This study provides new insights into similar engineering problems.
Automatic Parts Correspondence Determination for Transforming Assemblies via Local and Global Geometry Processing
Authors: Shibuya Hayata , Nagai Yukie
Published: March 2023

Transforming assemblies are products that alter their shapes by re-assembling their parts. This idea is applied to a wide range of objects from folding gadgets as outdoor gear aimed at saving space, to robotic characters fighting in Hollywood films which drastically change their appearance. While the former type falls into a folding or packing problems, the latter requires a different viewpoint to be solved since the destination shape is not necessarily aiming at minimizing the occupation space. As a possible solution, this kind of deformation can be decomposed into segmentation of the shape to parts and parts matching. Segmentation is a general problem in shape modeling and numerous algorithms have been proposed for this. On the other hand, matching simultaneously multiple parts (many-to-many matching) has hardly been explored. This study develops a many-to-many matching algorithm for surface meshes of parts from two distinct destination shapes of a single transforming assembly. The proposed algorithm consists of a local geometry analysis and a global optimization of parts combination based on such analysis. For the local geometry analysis, the surface geometric feature is described by a local shape descriptor. Some vertices are detected as feature points by intrinsic shape signature (ISS) and the geometry at the feature points is expressed by the signature of histogram of orientation (SHOT). For all the combination of pairs from each destination shape, the number of feature points with similar descriptor values is counted. In the global optimization, the final matching is determined by the maximum weight matching on a complete bipartite graph whose nodes are the parts, and edges are weighted by the number of the feature points with similar descriptors. We present successful results for several examples to empirically show the effectiveness of the proposed algorithm.
Utilization Method and Effect Evaluation of Systems Thinking in Future Design: Comparative Analysis of Policy-Making Workshops in Local Governments
Authors: Nomaguchi Yutaka , Senoo Ryotaro , Fukutomi Shinya , Hara Keishiro , Fujita Kikuo
Published: March 2023

The Future Design (FD) workshop (FDWS) is a discussion framework based on FD. The aim of FD is to activate a human trait calledfuturability, considering the preferences of future generations. Previous FD practices with the theme of policy-making in local governments have demonstrated this possibility. However, creating concrete proposals might depend on workshop participants’ abilities and emotions to perceive future society. By comparing two case studies, this study examines the effects of a method for utilizing a causal loop diagram (CLD), a tool for systems thinking, in FDWS to systematically draw the future society and activate discussions among the participants. CLD is a qualitative system model that helps identify the factors that lead to systemic problems and analyze the guidelines for solving them. Its effects on the performance of the FDWS discussion activity are evaluated. They are quantified by text mining analysis using participants’ remark records. Two case studies conducted at policy-making workshops in the local governments of Japan are examined. One is the FDWS in Kyoto City which adopted the proposed CLD utilization method, and the other is the FDWS in Suita City without CLD. The comparative analysis demonstrates that the proposed method makes the discussion livelier, less divergent, and more developed in the FDWS.

Authors: Tohari Chamim
Published: March 2023

This study examines the contribution of the Regional Leaders of Muhammadiyah Bojonegoro in an effort to stem the outbreak of the radicalism movement. The problem is limited to the following: (1) What are the views (regarding the definition, characteristics, and statements of agreeing or disagreeing) of Muhammadiyah leaders in Bojonegoro towards the Islamic radicalism movement? (2) What efforts can be taken by Muhammadiyah in Bojonegoro in stemming the spread of Islamic radicalism in society, especially in Bojonegoro? (3) In the field of da’wah, what strategies are used to minimize the possibility of spreading Islamic radicalism in society? The results of this study are: First, regarding the definition of radicalism according to figures and leaders of Muhammadiyah Bojonegoro, it is understood as a movement that wants to completely change the social order in unconstitutional ways. Among Muhammadiyah figures in Bojonegoro considers that radicalism is a product of conspiracy, so that in this context the meaning of radicalism is biased. However, all Bojonegoro Muhammadiyah leaders agreed that Muhammadiyah refused and would fight radicalism. Second, among the efforts/contributions of the Bojonegoro Muhammadiyah Regional Leaders in overcoming radicalism are manifested in various work programs such as implementing the policies of the Muhammadiyah Central Leadership to enlighten the community by showing the face of Islam that is rahmatan li al-‘alamin. Third, Muhammadiyah Bojonegoro does not use a special strategy either in the field of da’wah and in other fields related to combating radicalism, because in general the Muhammadiyah movement from the central level to the lowest level is a movement that shows the spirit of wasathiyah/moderate, inclusive, and promotes tolerance. But the most tangible contribution made by Muhammadiyah Bojonegoro is to instill moderate religious understanding in the community in a structured and systematic manner. The contribution of this research is to provide solutions for the government and society in general on how to spread the spirit of religious moderation structured and systematic.

The Juridical Study on the Implementation of the Ijarah Muntahiya bi at-Tamlik Contract in the Concept of Luzumu al-‘Aqdi
Authors: Bawono Bambang Tri , Laksana Andri Winjaya
Published: March 2023

The purpose of this study was to examine and analyze the implementation of the Ijarah Muntahiya bi at-Tamlik contract in the conception of Luzumu al-‘Aqdi. The approach method used in this research was sociological juridical. The results of this study indicated that the implementation of the Ijarah Muntahiya bi at-Tamlik contract at Bank Syariah Indonesia (Indonesian Sharia Bank, BSI) Semarang Branch Office in the concept of Luzumu al-‘Aqdi actually shows the occurrence of legal uncertainty. This is because the implementation of the Ijarah Muntahiya bi at-Tamlik contract should only be carried out through buying and selling, not grants. The implementation of the Ijarah Muntahiya bi at-Tamlik contract can only use a sale and purchase contract because this contract is part of the ijarah contract which aims to obtain profit or profit, while the grant contract is one of the tabarru’ contracts which aims to help each other and seek the pleasure of Allah alone. Besides that, implementation of the Ijarah Muntahiya bi at-Tamlik contract settlement through the sale of the Ijarah Muntahiya bi at-Tamlik object results in legal uncertainty, so that this has the potential to harm the musta’jir or the debtor in the event of bad credit or default. This is because the musta’jir or debtor should not be said to have debt, considering that the contract that is built is ijarah first which will end with ownership through buying and selling or grants, not buying and selling which is required by ijarah because its implementation is carried out in installments.

Using path analysis with external model measurements, mediation tests, and internal model measurements. The results showed that transformational leadership had a significant positive effect on the work environment, organizational culture had a significant negative impact on the work environment, and work environment had a significant positive effect on work performance. The work environment can mediate the influence of transformational leadership on work performance. In comparison, the work environment has yet to mediate organizational culture's effect on performance. This research contributes to the relationship between transformational leadership behavior, organizational culture, work environment, and employee performance. Various variables are tested to provide results and a more comprehensive understanding of employee performance factors. Therefore, institutional leaders must have transformational abilities, work culture, and the environment by obtaining good information about their employees to achieve expected or significant results.

With the rapid development of technology, an application for online shopping (marketplace) was born. One of the largest in Indonesia is the Shopee marketplace. In the Shopee application there is a payment feature that can be made in stages, known as Spaylater. In this study, the theory used is the sale and purchase contract, loan contract, hiwalah contract and usury. This research uses the type of field research or field studies using a qualitative approach. This research was conducted on the Shopee application, where in the Shopee application there is an online loan feature called Spaylater. This feature makes it easy for users to make transactions, because Spaylater itself offers bailouts for users who want to transact but do not have cash. Then the researchers used primary data obtained from interviews with informants in accordance with the research problem. While secondary data, researchers obtained from books, journals, articles from the internet, DSN-MUI Fatwa and theories related to Islamic law. Then for the data collection method using observation, interviews and documentation. The results of this study indicate that if the activation of the Spaylater user is successful, the user can use the limit that has been given. Then regarding the view of Islamic law, looking at Spaylater, namely in the Spaylater mechanism there are conditions for contracts that are not fulfilled in Spaylater. Because in it there is a late fee given by the Spaylater, this late penalty is included in usury jahiliyah. Therefore the practice of Spaylater is not allowed in Islam because it contains elements of usury.

Primary mucinous cystadenocarcinoma (MCA) of the testis is extremely rare, only 10 cases having been reported to date. Metastases of mucinous adenocarcinomas that have originated in different sites can mimic primary MAC and must be included in the differential diagnosis. We report a case of primary MCA of the tunica vaginalis testis in a 28-year-old patient who presented with a painless mass on the left side of the scrotum. We present the clinical and pathological characteristics to contribute to the further understanding of these rare tumors.

Anaplastic pleomorphic xanthoastrocytoma (APXA) is a rare and aggressive brain tumor that requires a multidisciplinary approach for proper diagnosis and treatment. This case report presents the case of a 15-year-old male patient diagnosed with APXA in the left temporal region. The patient underwent a combination of imaging studies, including MRI, followed by a biopsy of the tumor tissue and surgery. The patient was then closely monitored for recurrence and progression of the tumor, and further received six cycles of chemotherapy and radiation therapy. This report aims to provide detailed information about the diagnostic process for APXA, which can be challenging due to its similarity to other tumors, such as pilocytic astrocytoma. Additionally, the report highlights the varying treatment options and outcomes for patients with APXA, as well as the importance of close monitoring for the recurrence and progression of the tumor. More research is needed to fully understand the best treatment options for APXA and to improve outcomes for patients diagnosed with this rare and aggressive brain tumor.

Background: Currently, comorbid patients with chronic obstructive pulmonary disease (COPD) and obesity are becoming increasingly common in clinical practice. The objective of this study was to conduct a comparative analysis of indicators of various types of body metabolism (carbohydrate, lipid, adipokine profile) in COPD patients with obesity and normal body weight. Methods and Results: The study included 86 patients with COPD (GOLD 3-4, group D). The diagnosis of COPD was established in accordance with GOLD, revision 2021.The patients were divided into two groups. Group 1 consisted of 43 COPD patients with NBW [31(72.7%) men and 12(27.3%) women aged 43 to 75 years (mean age of 62.40 ± 8.83 years)] and Group 2 consisted of 43 COPD patients with obesity [32(77.27%) men and 11(22.73%) women aged 48 to 72 years (mean age of 62.94 ± 5.96 years)]. All patients underwent an analysis of the composition of the body by the bioelectrical impedance method. Blood levels of total cholesterol (TC), triglycerides (TG), HDL-C, and LDL-C were determined by the enzymatic colorimetric method. The glucose level was determined by the glucose oxidant method. The serum adipokine levels (leptin, adiponectin, resistin), as well as testosterone and immunoreactive insulin, were determined using ELISA. To assess insulin resistance, the HOMA-IR index was calculated. To determine cardiovascular risk, the visceral adiposity index (VAI) was calculated according to the formula, which considers body mass index, triglycerides, HDL-C, and waist circumference. The level of HDL-C was significantly lower (P=0.0000)), and the levels of TC (P=0.0479), LDL-C (P=0.0020), glucose (P=0.0020), immunoreactive insulin (P=0.0000), and HOMA-IR index (P=0.0000), were significantly higher in Group 2 than in Group 1. As for the content of adipose tissue hormones, the leptin level was significantly higher in Group 2 (P=0.0000) than in Group 1, while there were no statistically significant differences between groups in the level of resistin (P=0.4996). The adiponectin level was significantly lower in Group 2 than in Group 1 (P<0.0001). The VAI level in Group 2 was significantly higher than in Group 1 (2.13±1.56 and 1.18±0.41, respectively, P=0.0002). In contrast, the testosterone level was significantly lower in Group 2 than in Group 1 (10.59±6.94 nmol/l and 20.02±12.25 nmol/l, respectively, P=0.0000). Conclusion: The high metabolic activity of adipose tissue in patients with COPD and obesity is directly related to the progression of comorbid conditions.
Characterization of Incidental Liver Lesions: Comparison of Multidetector CT versus Ultrasonography
Authors: Osman Hanady
Published: March 2023

Background: Due to recent advancements in imaging techniques, as well as the widespread use of routine medical exams and screenings, incidental LL are now more frequently discovered by US. Physicians must decide whether to simply follow up when incidental LL are discovered in the US or to order additional imaging tests for lesion classification. The goal of our study was to identify LL using MDCT and US. Methods and Results: A total of 50 participants were selected from a variety of male and female patients with abdominal pain and suspected liver diseases, and received a CT triphasic scan and US at the Royal Care International Hospital, Ibn Alhaitham Diagnostic Center, Alfaisal Specialized Hospital, and the Department of Diagnostic Radiology in the CT department of Sudan from April 2018 to May 2020. The results of the ultrasound scanning (liver lesions and related findings) performed on patients before the CT scanning indicated that ascites+ liver lesions was predominant (48.6%). The incidental liver lesions that take peripheral nodular enhancement by MDCT when contrast media is injected, were liver metastases (30%), hemangioma (14%), and HCC (10%). Liver cysts represent 10(20%) of the total cases of lesions that were non-enhanced by CT, with a few cases of liver cirrhosis (2%), hepatosplenomegaly (2%), and cyst + hepatitis (2%). We found a significant relationship between peripheral nodular enhancement for liver lesions by MDCT and non-enhancing liver lesions (P=0.001). Conclusion: The US and CT scan findings have a statistically significant relationship (P≤0.017). Contrast-enhanced CT performs better at diagnosing liver lesions than does standard US.

Background: The goal of this study was to measure normal Achilles tendon (AT) thickness and width in adult asymptomatic Sudanese people using high-resolution ultrasound. Methods and Results: The study was conducted on members of a healthy Sudanese population (120 volunteers: 73/60.8% women and 47/39.2% men), who were chosen using simple random sampling. The study cases were all healthy people with no history of AT injuries or abnormalities. All patients were examined using a Toshiba Xairo200 linear transducer with a frequency range of 7-10MHz. All measurements were taken from a transverse scan at the calcaneus bone level of the AT insertion and 2 to 3cm above the calcaneus. The age group 20-27 had the most participants (44.2%), followed by 36-43 years (19.2%), 28-35 years (15.8%), 52-60 years (14.2%), and 44-51 years (6.7%). The study revealed that the mean age of participants was 34.19±12.29 years, height - 164±0.081 cm, weight - 67.22±15.97 kg, and BMI - 24.38±5.84 kg/m2. The mean thickness and width of the AT were 4.36±0.81 mm and 21.85±3.23 mm, respectively, at its insertion into the calcaneus, and 4.63±0.77 mm and 12.20±1.37 mm, respectively, at the level 2-3 cm above the insertion. We found significant differences according to gender between the AT thickness and width at insertion into the calcaneus and above insertion and no statistically significant differences between the AT measurement's right and left side data. Conclusion: The study found gender differences in the AT thickness and width at insertion into the calcaneus and 2-3 cm above the insertion. No statistically significant differences were detected between the AT measurement’s right and left side data.Age, weight, height, and BMI correlated with the thickness and width of the AT at its insertion into the calcaneus and 2-3 cm above. Furthermore, additional research should be conducted using an extended field-of-view technology to measure the length of the AT tendon in the Sudanese population.
