The article is devoted to the development of economic and mathematical tools for assessing the level of investment attractiveness of oil companies. It is noted that the oil industry is the driver of economic development of any country. The spread of the COVID-19 pandemic has caused a significant problem of instability in the Russian oil sector. This problem is of a strategic nature and its solution requires the activation of investment in the oil complex enterprises and, as a result, the development and use of model tools to assess the level of investment attractiveness of investment objects. The economic and mathematical model proposed in this article is based on the application of the mathematical apparatus of fuzzy logic and allows us to give a quantitative assessment of the investment climate of oil companies when operating with qualitatively defined characteristics (multipliers).

An efficient method has been developed for the synthesis of some derivatives of tetrahydropyrimidine-5-carboxylates based on the three-component condensation of various aldehydes and β-diketones with thiocarbamide. The antioxidant properties of the synthesized compounds were studied in model reactions by the kinetic method.
Is IPO Underpricing a Corporate Strategy?
Authors: Hua Wei
Published: November 2022

To determine whether Initial Public Offering (IPO) underpricing is a corporate strategy and could improve a firm’s long-run performance, I investigate whether IPO underpricing could promote or impede a firm’s innovation productivity. I use the firms listed in China’s Growth Enterprise Market (GEM) during the period from October 2009 to February 2017. The results of Ordinary Least Sqaure (OLS) show that underpricing is negatively related to innovation productivity, measured as the number of patents. It suggests that managers or underwriters only care about the immediate return and capital accumulation from IPO, rather than a firm’s future growth. Managerial myopia is detrimental to a firm’s long-term survival and development. Difference-in-Difference (DiD) methodology further establishes causality between underpricing and the number of patents, which compares the difference in the number of patents between the three-year window before IPO and after IPO.This probably suggests that IPO underpricing is not an active strategy to target long-term survival and growth. Industry and IPO suspension are also included to solve the effect from unobservable shock on the firm’s innovative capability. My future study could expand to discuss the channel through IPO affect the firm’s innovation productivity.

Published: November 2022

This research aimed to 1) create a charism model for personnel administration of school under the ‘Sisters of Saint Joseph of the Apparition’ in Thailand, in order to increase the commitment of personnel to the organization, and 2) demonstrate and improve the charism model. The research process was divided into three steps as follows: 1) developing a charism model, 2) demonstrating the model, and 3) enhancing the model. The findings revealed that the charism model for personnel management consisted of two factors. The first factor (charism) included 1) Agape Love, 2) Humility, 3) Altruism, 4) Vision, 5) Trust, 6) Service, and 7) Empowering. The second factor (personnel management) included 1) Planning, Recruitment and Positioning, 2) Promotion, Absence and Evaluation, 3) Performance, 4) Disciplinary Work and History Registration, 5) Code of Professional Ethics, and 6) Other Tasks Assignment. The researcher also developed a charism-based integrated personnel management manual for Saint Emilie school. The demonstration of the results revealed that lecturers and staff were satisfied with personnel management at the highest level. As the researcher considered each variable, the operational aspect had the highest average score, whereas salary, promotion, taking leave and evaluation had the lowest score. The six dimensions of the charism model for improving personnel administration were adjusted accordingly.
Numerical Investigations on Operation Modes and Transients of IPM Machines with Dual Windings
Authors: GÜNDOĞDU Tayfun
Published: November 2022

This paper investigates the flux-weakening characteristics and transient response of a dual winding interior permanent magnet (DWIPM) machine designed using the 2010 Toyota Prius IPM Machine specifications. In order to thoroughly adjust the main flux, dual windings are fed by separate identical inverters. Thus, significantly high-torque for high-speed requirements can be simply achieved by making one of the inverters open-circuited. Transient response of the DWIPM machine, including torque and current pulsations, occurring during normal drive or deactivation of one of the inverters has also been investigated for different operation modes. The flux-weakening performance characteristics of the proposed DWIPM machine have been compared with those of its single-fed counterpart in order to highlight the benefits and drawbacks of the dual-winding topology. The steady-state performance characteristics, torque/speed and power/speed curves, efficiency maps, machine transient response, different machine design options with various numbers of turns per phase and current amplitudes, and the importance of the electromagnetic coupling between dual windings have all been addressed. For transient and steady-state analyses, 2D, nonlinear, time-stepping finite element method (FEM) has been employed. It has been revealed that the proposed DWIPM machine exhibit significantly improved flux-weakening characteristics, particularly high-power at constant power region and high efficiency at constant torque region, and quite low current and torque pulsations occurring during operation mode change.

Published: November 2022

Recent studies shed an unfavourable light on existing tools that support at-distance learning in pre-university students. Concerns revolve around motivation, focus, engagement as well as long-term knowledge retention rates. Multiple attempts were made to connect digital games with education, designated by Game-Based Learning, although educational outcomes have been mixed. Possibly due to ad-hoc experimentation, the effects seem related to relationships between specific game mechanisms and structural design. This research project focused on potential effects of a digital 3D role-playing game in learning. A multidisciplinary team built a prototype, named Liber Domus, using game developing techniques and mechanisms that have never been used or explored in the area on this scale. Preliminary results show the game presents students with a more dynamic approach to learning inside the classroom, increasing motivation and fun levels and allowing for a less repetitive revision of subjects, and the flexibility of the tool for both classroom and at-home learning. Further development is ongoing.
Can Bloom's Higher Order Thinking skills be achieved by Gamified Learning through Social Networking Site (SNS) like Facebook?
Authors: Nagarajan Amuthageetha , Sen Arkendu
Published: November 2022

Medical students commonly may resort to rote learning of complex medical topics such as neuroanatomy, primarily if they disengage and work in silos. Providing students with engaging and interactive content, especially of Higher Order Thinking Skills (HOTS) of Blooms, to understand such complex topics and simultaneously providing an opportunity for collaborative learning can be beneficial. This can allow authentic learning towards competency to handle complex medical issues. To address this, the present study developed a novel social network site using three key aspects: An integrated curriculum delivery approach with the integration of games to stimulate creativity (Gamified content), real-life medical scenarios (authentic Case-based learning), and the provision of a social networking platform (Facebook) to voice ‘students’ thoughts through simple, group brainstorming in an informal learning space (social media). Innovatively ‘Bloom’s taxonomy is used to create gamified quizzes of increasing difficulty levels and HOTS levels. We identify’ students’ engagement and learning effectiveness of social networking and gamified learning by medical students over traditional learning management systems. The Lecturers’ feedback also evaluates how well the learning outcomes are planned to be achieved through the learning designs of such games. We found that this learning design combining SNS with games at various levels enhanced the learning processes.

Published: November 2022

Despite the increasing use of simulation games in business education, only few studies have explored the cognitive processes that learners employ while playing the game, with quite controversial results about the students’ learning outcomes. The current study analyses the impact of a Business Simulation Game (BSG) on the cognitive processes related to the “Structure of the Observed Learning Outcome” (SOLO) taxonomy. Moreover, overall learning performance and perceived teamwork competency have been investigated. A quasi-experimental pre and post-test design was applied. Eighty (80) university students played a marketing simulation game to practise a business marketing plan. The results showed a significant improvement in the unistructural and extended abstract levels of the taxonomy after playing the game. There was no significant difference in the multi-structural level while the effect on the relational level was negative. Also, a strong, positive correlation between perceived teamwork competency and learning performance was found. Implications for instructional designers and educators are discussed.

Issues such as climate change and ever-increasing global warming have obliged governments and world authorities to comply with stringent regulations on the control of greenhouse gas (GHG) emissions in internal combustion engines (ICEs). Carbon dioxide (CO2), the most produced GHG, has been the major concern of climate change in recent years. To reduce carbon emissions, fuels with lower carbon content, such as alcohol fuels, or fuels with no carbon content, like hydrogen and ammonia, should be taken into consideration to be replaced by fossil fuels in internal combustion engines.

Authors: Walaa Mohamed Omar Ashry  , Mahmoud Mohammed Moawad  , Salah Mohammed Abd-Elghany
Published: November 2022

Introduction and aim: Diabetic foot ulcers are a serious medical and economic worry. It is the most common reason for diabetic patients to be admitted to hospital. If not treated appropriately, the infection might lead to amputation of the infected foot. The current research aims to recognise the frequencies of isolated aerobic bacterial pathogens associated with diabetic foot ulcers and detect their antibiotic susceptibility and resistance patterns to reduce the risk of complications.
Methodology: This cohort study included 140 swab samples from diabetic foot ulcers from patients referred to the surgery department at Al-Azhar University Hospital in New Damietta, Egypt, in the period between January and December 2018. All samples were processed for the identification of aerobic bacterial strains were identified using routine bacteriological culture methods and antimicrobial susceptibility by the Kirby-Bauer disc diffusion method.
Results: Out of 140 pus and tissue samples obtained of diabetic foot ulcers, 120 (85.7%) exhibited aerobic organism growth, yielding a total of 132 isolates with an average of 1.1 isolates per specimen. Polymicrobial infection was 10%. Gram-negative isolates were prominent (62.88%), with Pseudomonas aeruginosa (26.5%) being the most common strain causing diabetic foot infections, followed by E. coli (20.5%). Staph aureus was the most common Gram-positive bacteria (8.9%). Out of 83 Gram-negative bacteria, 54 (65%) produced extended-spectrum lactamase (ESBL). The majority of Gram-negative isolates were resistant to levofloxacin, gentamicin, ampicillin-sulbactam, and gatifloxacin. All Gram-negative bacteria were sensitive to imipenem. Of the 25 Staph aureus, 15 (60%) were Methicillin Resistant Staphylococcus aureus (MRSA) and susceptible to vancomycin and linezolid.
Conclusion: Pseudomonas sp. was the most prevalent cause of infections. Most isolates were multidrug resistant. In our study, Gram-negative bacteria were the main cause of diabetic foot infections. A significant number of MDR isolates were also observed. The inappropriate use of broad-spectrum antibiotics may be the main cause of the increase in the frequency of MDR isolates.

Published: November 2022

Introduction and aim: Obesity is a worldwide epidemic and nearly affects every organ. However, the renal changes in obesity are not sufficiently addressed. Thus we aimed to investigate the effects of high-fat diet induced obesity on the kidney and explore the effect of caloric restriction on the renal changes associated with obesity.
Methodology: Thirty male albino rats, 160-180 g included and divided into three equal groups. The first is the control group (received nothing except normal diet). The second is the high fat diet-fed group, where rats fed on high fat diet for 12 weeks. The third group fed as the second one for 12 weeks followed by diet restriction for 6 weeks by feeding on normal chow diet. The following measurement were recorded: 1) Initial and final body weight, 2) serum value of different biochemical parameters (lipid profile, glucose, insulin, cytokines, inflammatory markers and renal function tests). Finally, kidney was extract, fixed and prepared for histopathological examination.
Results: The final weight significantly increased in the obese than the control and diet restriction groups (421.0±17.13 versus 279.50±11.17 and 333.0±13.33 g, successively). The total cholesterol, TG, LDL, vLDL, glucose, insulin, HOMA-IR, IL-6, leptin, resistin, TNF-α, CRP and Plasminogen activator inhibitor-1, creatinine, urea, protein in urine, uric acid were significantly higher in obese than control and diet-restriction groups. However, HDL and adiponectin were significantly reduced in obese than the control and diet restriction groups. The diet restriction significantly improved laboratory values, but it remains significantly different than the control group. The correlation between weight gain with other variables and renal structural changes confirmed the laboratory results.
Conclusion: Obesity is associated with functional and structural renal changes. The potential mechanisms involve inflammation, lipotoxicity and perhaps other unknown mechanisms. Weight reduction constitutes the most effective intervention to guard or treat obesity-associated chronic kidney disease.

Published: November 2022

Central neuraxial blocks (CNBs) relevant to the practice of obstetric anesthesia and analgesia are spinal, epidural and combined spinal-epidural injections. These techniques are routinely used for cesarean deliveries and labor pain relief. Traditionally, CNBs are performed using surface anatomical landmarks. In the first instance the highest point of each iliac crest is identifies. The imaginary line connecting these points allegedly passes through the L4 vertebral body in non-pregnant women, and L3 vertebral body in pregnant women [1]. Based on this, the operator palpates and counts the spinous processes and decides on the needle entry point. Although this technique is widely accepted as relatively reliable, the correlation is inconsistent even in non complicated cases. Obesity, tissue edema, pelvic rotation, limited ability to bend forward, hyperlordosis, labor pain, underlying spinal deformity or previous back surgery and instrumentation pose additional difficulty for anesthesiologists to correctly locate the intervertebral levels.

A 91-year-old woman with primary complaints of abdominal pain and vomiting visited our hospital. Abdominal computed tomography revealed an ileocecal tumor with ileal dilation (Figure 1a). Colonoscopy (PCF‐Q260AZI; Olympus, Tokyo, Japan) revealed a circumferential cecal tumor invading the ileocecal valve (Figure 1b). A biopsy revealed adenocarcinoma, which was diagnosed as ileocecal cancer, resulting in obstruction. Surgery was deemed difficult due to her dementia and bedridden status. We placed a palliative colonic self-expandable metal stent (SEMS), with informed consent from her family. A 0.035-inch guidewire (JagwireTM, Boston Scientific Japan, Tokyo, Japan) was advanced to the ileum side, and an endoscopic retrograde cholangiopancreatography catheter was inserted through the guidewire to perform gastrografinography. The stenosis had flexion and was 60 mm in length. We selected HANAROSTENT NaturfitTM (22 mm × 9 cm, M. I. Tech, Seoul, Korea), as this could be placed with the side inside the large intestine (Figure 2a, c). We confirmed that the stent was patent and did not deviate by X-ray (Figure 2b, d). The patient was able to resume eating immediately and remains asymptomatic after three months.

A 65-year-old man with a history of left renal cell carcinoma 25 years ago underwent left nephrectomy and was regularly followed up. Last year, positron emission tomography showed mediastinal lymph node enlargement. Bronchoscopic biopsy revealed cancer recurrence and metastasis. We administered ipilimumab (1 mg/kg) and nivolumab (4 mg/kg) combination therapy. A week later, he developed diarrhea and abdominal pain. Colonoscopy revealed a reddish edematous mucosa with erosions and ulcers from the terminal ileum to the ileocecal valve (Fig. 1A, B). Terminal ileum biopsy revealed lamina propria by inflammatory cell infiltration; however, no crypt abscess or apoptotic bodies were observed. The colon and esophagogastroduodenoscopy findings were normal (Figure 1C, D). Small intestinal capsule endoscopy revealed redness and edema in the jejunum (Figure 2 upper). From the deep jejunum to the ileum, and further into the ileum, common villi, erosions, and ulcers became apparent (Figure 2 lower). Tests for stool bacteria, cytomegalovirus, and other viruses were negative. Therefore, his condition was diagnosed with immune-related enteritis. His symptoms did not improve after stopping ipilimumab and nivolumab. Treatment with predonisolone 40 mg/day immediately improved his symptoms.

Traditional institutions as a medium in the process of holding a ceremony, including the traditional Lodo Huer ceremony. In Kajowair Village, hewokloang sub-district, there are traditional institutions that play a role in this process of traditional rituals as referred to as the Lodo Huer custom called Rawin. Traditional institutions (Rawin) have a very important role in the traditional ritual of lodo huer, namely before the traditional ritual ceremony begins, the traditional institution performs a ceremonial ceremony as the opening for the lodo huer ceremony. The traditional institution (moan rawin) as the leader before and after the traditional ceremony take place. The process of the traditional lodo huer ritual in Kajowair Village, Hewokloang sub-district cannot be separated from the role of traditional institutions. Indigenous institutions have a very important position in this regard which relates to common interests in the process of sustaining the traditional ritual of lodo huer, in order to achieve common goals and the welfare of indigenous peoples. Traditional institutions represent indigenous peoples in managing and regulating the implementation of the traditional lodo huer ritual process in Kajowair Village which is believed to be a tradition that is passed down from generation to generation. "Traditional institutions have a very important role in providing opportunities for young people during the process of the Lodo Huer traditional ceremony, starting from the beginning of the activity starting until the end of the Lodo Huer traditional ceremony. This means that during the process of the traditional Lodo Huer ceremony, it is very dependent on traditional institutions. “In the traditional Lodo Huer ceremony there are 7 (seven) main events that must be carried out, namely the first one is poto pare, the second is tokang nuhun, the third is wake l'oe, the fourth is pero urun papa blatan, the following are 'ea gete, nara krus and the last the last one is pa'at krus” “Efforts are being made to preserve the traditional lodo huer ceremony by giving lessons to young people to learn more about what is done during the process of the traditional lodo huer ceremony so that it remains preserved and carried out as a tradition that has never been lost and extinct

Published: November 2022

Learning readiness is a condition of students who are ready to take lessons in terms of giving responsis or answers in both physical and mental abilities. Based on a survey conducted at SMA Negeri 1 Talibura, many students were not ready to receive economics. This is seen by the lack of student’s attention when the teacher explains the material in front, so the that the material delivered by the teacher is not accepted by students and there are still many students who do not study the material in depth so they only depend on the material delivered by the teacher alone. In addition, students only have a reference book prepared by the school, students should also have to have othercompanion books so that they can add to their horizons. This research was conducted at SMA Negeri 1 Talibura with the aim to determine the effect of learning readiness on learning outcomes economic subjects in class XI SMA Negeri 1 Talibura. The population in this study was the whole of the research object, namely the number of all students of class XI Social Sciences. The sample used in this study was a random sampling technique.
