Authors: Marlissa Elsyan Rienette
Published: December 2022

Purpose: The purpose of this study was to determine the factors supporting and inhibiting the income of traders in the RI-PNG border area.
 
Theoretical framework: In the trade process, Producers have a very important role in the process of buying and selling transactions. Producers are faced with driving factors which can support and influence the business so that it can progress and develop so as to increase the income received.
 
Design/methodology/approach: This study uses secondary data in the form of interviews using questionnaires. The analytical tool used is Force Field Analysis (FFA) to see the factors supporting and inhibiting the income of producers (traders) in the RI-PNG border area.
 
Findings: The results of the study based on the FFA analysis conducted stated that the highest key success factor in the supporting factor was the cooperative relationship between producers (traders) and the government, while the inhibiting factor was the low quality of human resources.
 
Research, Practical & Social implications: The results of this study can be used by policy makers, namely the government in connection with the known supporting and inhibiting factors in order to make policies that can increase the income and welfare of producers as well as provide benefits to the state.The results of this study can also be useful for the community at large because it opens their understanding of trade conditions in the RI-PNG border area, as well as factors that support and hinder, so that it can become new knowledge in the community.
 
Originality/value: The RI-PNG border area can become an area of economic growth because of the economic activities that occur. Various potential products can be traded through trade that occurs at the border. Therefore, besides focusing on infrastructure development around the border area, the government also needs to improve the character of the community so that they are able to compete in the trade to increase the community's income.The difference from previous research and this research is that most of the previous research only focused on the topic of producer income. Meanwhile, this study focuses on the factors supporting and inhibiting the opinion of producers in the RI-PNG

Authors: Altameemi Arshed Fouad , Al-Slehat Zaher Abdel Fattah
Published: December 2022

Purpose: The objective of this study was to investigate the effect of Islamic financing on commercial banks’ credit facilities tested under the mediation of the two variables of Islamic bank size (Total asset and Investment deposit).

Theoretical Framework: Even though studies of Islamic banking funding have been done within the Islamic economics and finance context, there has been needed to explore the effect of mediating the size of the Islamic bank and the relationship between Islamic financing and commercial banks’ credit facilities.

Design/Methodology/Approach: We used the methodologies of Baron and Kenny (1986) and Preacher and Hayes (2008) to test a mediation effect of the Islamic bank size variable. Regarding the testing and validity of the hypothetical research model, path analysis was used within the structural equation modeling analysis. The study sample consists of 16 commercial and Islamic banks in the Jordanian banking sector, it is comprehensive of all listed banks' data in the Amman stock exchange, to the possibility of fairly generalizing the results to the community.

Finding: Results indicate that the two variables of size indicators may partially mediate the direct effect of Islamic financing on commercial banks’ credit facilities. Such an effect is statistically significant. The findings provide practical solutions to enhancing competition in the Jordanian commercial and Islamic banking services market through various Islamic financing services to maintain and sustain banking resources.

Research, Practical & Social implications: Future studies can consider other indicators of Islamic bank size and assess their influence on the various dimensions of the relationship between Islamic funding methodology and commercial bank facilities

Implications/Originality/Value:  This study contributes to the literature on Islamic banking by analyzing the results of the effect of Islamic investment financing formulas on the commercial credit market in Jordanian banking, and it offers a practical and applied perception of the role played of the Islamic banking methodology in the Jordanian commercial credit market.

Authors: Chan Arianis , Suryadipura Dadan , Novel Nurillah Jamil Achmawati
Published: December 2022

Purpose:  This study evaluates the contribution of symbolic brand elements such as the destination name, logo, and tagline to forming a destination brand.

 

Theoretical framework: Branding is identified with a symbolic element in a product. In the context of destination branding, an emblem or logo promises a tourist experience that can be remembered and associated with a particular destination by tourists or visitors. (Mihalis Kavaratzis & Hatch, 2013)

 

Design/methodology/approach:  The article reports on field research that operationalizes a theoretical framework to examine visitor perceptions of West Java—involving 322 respondents, namely visitors to tourist destinations in West Java.

 

Findings:  The name of the destination is the most contributing element to the formation of the West Java destination brand. In addition, the name of the destination is accessible for visitors to remember and influences their visit decision. However, according to respondents, taglines and logos are also essential elements in branding destinations in West Java.

 

Research, Practical & Social implications: We suggest a future research agenda and highlight the symbolic brand elements in the form of brand names, logos, and slogans (or taglines) that contribute to overall destination branding in other city or country.

 

Originality/value:  The results of this study indicate the role of the brand element of the destination name can also influence the decision of tourists to visit the destination. The results refer to brand elements (at least the tagline and logo) which are “important” for branding West Java city/district destinations.

Authors: ÇAKAN Ahmet , UĞURLU Mustafa
Published: December 2022

DP600 steel and AA7075-T6 aluminium alloy plates were joined using the friction stir spot welding process. The effects of different tool rotational speeds on the mechanical properties, intermetallic compound formation and interface microstructure of welded joints were investigated. The highest lap shear tensile load was obtained from the samples joined at a rotational speed of 1040 rpm (6.5 kN). It was determined that the tensile load of the welded joint decreased with increasing tool rotational speed. XRD analysis performed on broken surfaces, the intermetallic phase was determined to be Al13Fe4. As a result of Vickers microhardness tests, the samples joined at 1320 rpm and 1500 rpm, in the structure of which intermetallic compounds were determined by XRD analysis, displayed higher hardness values. In addition, when scanning electron microscope images were examined, it was determined that the cracks observed in the samples and the porosity both increased with increasing tool rotational speed.

An Analysis of the Impact of Building Wind by Field Observation in Haeundae LCT Area, South Korea: Typhoon Omais in 2021
Authors: Kang Byeonggug , Kim Jongyeong , Kwon Yongju , Choi Joowon , Jang Youngsu , Kwon Soonchul
Published: December 2022

In the Haeundae area of Busan, South Korea, damage has continued to occur recently from building wind from caused by dense skyscrapers. Five wind observation stations were installed near LCT residential towers in Haeundae to analyze the effect of building winds during typhoon Omais. The impact of building wind was analyzed through relative and absolute evaluations. At an intersection located southeast of LCT (L-2), the strongest wind speed was measured during the monitoring. The maximum average wind speed for one minute was observed to be 38.93 m/s, which is about three times stronger than at an ocean observation buoy (12.7 m/s) at the same time. It is expected that 3 to 4 times stronger wind can be induced under certain conditions compared to the surrounding areas due to the building wind effect. In a Beaufort wind scale analysis, the wind speed at an ocean observatory was mostly distributed at Beaufort number 4, and the maximum was 8. At L-2, more than 50% of the wind speed exceeded Beaufort number 4, and numbers up to 12 were observed. However, since actual measurement has a limitation in analyzing the entire range, cross-validation with computational fluid dynamics simulation data is required to understand the characteristics of building winds.

Authors: Dainton Christopher , Jessani Ghazal , Hircock Caroline
Published: December 2022

Background

COVID-19-related travel restrictions profoundly impacted short-term medical missions (STMMs) abroad. This study describes the effect of the pandemic as perceived by STMM organisations serving Latin America and the Caribbean (LAC).

Methods

Information was updated for 359 primary care STMM organisations previously active in 2015, which were contained within an existing online database. Organisations were contacted to complete an online survey that gathered quantitative and qualitative descriptions of pandemic-related adaptations and program changes.

Results

22.5% (73/324) of previously active organisations had no website activity since 2020 or earlier, no longer existed, or had unclear website activity. Eighty-seven organisations responded to the survey. Ninety-six percent indicated that they would definitely (72/86, 84%) or probably (10/86, 12%) return to sending STMMs in the next five years, and most (46/83, 55%) of these intended to send an STMM within the next six months. Seventy-two respondents (93%) reported new adaptations, including direct funding for local healthcare professionals, sending equipment to host communities, focusing on training and teaching, and incorporating virtual care and electronic medical records.

Conclusions

The results demonstrate resilience, flexibility and optimism among STMM organisations and an intent to return to pre-pandemic programming rapidly.

Improvement of tools for specific prevention of avian salmonellosis
Authors: Ruzina A.V. , Pankratov S.V.
Published: December 2022

Avian salmonellosis is an infectious disease that occurs in an acute or chronic form and can be caused by one or more species of the genus Salmonella. The source of infection is sick and diseased birds, which can be carriers of Salmonella for a long time, i.e. reservoirs for the pathogen. In addition to chickens, other poultry, especially waterfowl (geese, ducks), as well as pigeons, rodents (mice and rats), insects (cockroaches), domestic animals and humans are also sources of infection. All this leads to a persistent epizootic environmental disease associated with a high risk of Salmonella contamination of industrial poultry. The modern control system of salmonellosis infection should be based on an integrated approach and include not only the implementation of veterinary and sanitary rules and the use of effective therapeutic preparations, but also the use of specific prevention of avian salmonellosis (vaccination). The aim of the study was to conduct the research on the physicochemical and immunobiological properties of inactivated vaccine against avian salmonellosis produced using different oil adjuvants developed by ICTYO GROUP Corporation. Formaldehyde inactivated S. enteritidis culture and a range of adjuvants (ICTYOLANETM11, ICTYOLANETM19, ICTYOLANETM20 and ICTYOLANETM 21) were used to produce the vaccine samples. The vaccine samples were tested for sterility, stability and viscosity by conventional methods. Determination of reactogenicity and antigenic activity of the vaccines was carried out on 38-day-old young laying hens. Upon completion of the tests, the inactivated emulsion vaccine against avian salmonellosis produced using the ICTYOLANETM 11 adjuvant was found to have very high antigenic activity and residual reactogenicity. It is likely that after a series of tests to reduce the residual reactogenic properties of the vaccine by reducing the number of S. enteritidis microbial cells in a single immunizing dose it will be possible to obtain a non-reactogenic and effective preparation for the specific prevention of avian salmonellosis based on the ICTYOLANETM adjuvant.
A Novel Method for Determining the Non-cds Region By Using Error-Correcting Codes
Authors: OZTAS Elif Segah , BULUT YILGÖR Merve
Published: December 2022

Our main motivation question is "Is there any relation between the non-coding region and useless error-correcting codes?". Then we focused CDS and non-CDS areas instead of exon and intron, because CDS involves in process of synthesis a protein and is involved by exons. We get the data of the genes from NCBI [21]. In this study, we introduce the method Fi-noncds that is used for determining the non-CDS region by using error-correcting codes. We obtained that the error-correction codes that can't correct any codes named zero error-correcting code, placed in non-CDS areas, densely. This result shows that non-CDS regions (non-coding areas in DNA) match zero error-correcting codes (useless error-correcting code). Frame lengths 7,8,9 and 10,11,12,13 and 14 were tested by the method. Optimal result for selected genes (TRAV1-1, TRAV1-2, TRAV2, TRAV7, WRKY33, HY5, GR-RBP2) is frame length 8, n=7, k=2, dnaNo=1. Moreover, optimal results of the algorithm Fi-noncds matched the best sequence length 8 as in [1].

Modeling Earthquake-induced Landslide initiation using the Fibre Bundle Model
Authors: Chen Yuanjing , Van den Bout Bastian , Lombardo Luigi , van Westen Cees
Published: December 2022

Co-seismic landslides are triggered by strong ground shaking in mountainous areas, resulting in threats to human activity and infrastructure. Methods for physically-based modelling of co-seismic landslide triggering play an important role in disaster prevention and mitigation. Current approaches, however, focus on direct and full failure of sloping rocks and soils,and do not cover the dynamics of partial damage and post-earthquake stability. In order to specify the seismic effect and simulate the dynamic failure process, we propose the use of Fibre Bundle Model (FBM), a mathematical framework to simulate the highly nonlinear behaviour of the progressive damage and breakdown of disordered media statistically. Soil on slopes are considered as bundles of fibres with a certain strength probability distribution. The damage in soil structure gradually increment during ground shaking. Our approach, integrating seismic forcing into the method, allows for prediction of partial damage, as well as full failure. We reach good validation results (AUC of 0.78). Due to the underlyingprinciples, the partial damage can be interpreted as a deterministic partial damage, or as a proxy for failure probability. The partial damage could be critical in predicting the impact of post-seismic landslide effects.
A breakthrough in fast flood simulation
Authors: Van den Bout Bastian , Jetten Victor , van Westen Cees , Lombardo Luigi
Published: December 2022

The current status of technological advancement does not allow to generate complete flood simulations in real-time for large geographic areas. This hinders warning-systems, interactive planning tools and detailed forecasts and as a consequence the population cannot be quickly or reliably informed of where large masses of water will flow. Our novel method computes flood hazard maps over three orders of magnitude faster than current state-of-the-art methods. It applies physically-based principles of steady-state flow to evade full dynamic aspects of flood simulations. It directly estimates the relevant information for flood hazard, such as peak flow height, velocity and flood arrival time. Performance indicators show similar or exceeding accuracy compared to traditional flow models depending on the type of event and quality of the used elevation data. In our tests, computational costs are reduced on average by a factor 1500. As a result, the developed method provides new perspective for the field of flood hazards, flood risk reduction through new types of early-warning systems, and user-interactive hazard assessment systems. As climate change is expected to aggravate flood hazard, the presented method can bring necessary efficiency to flood simulation and thereby save lives and livelihoods.
On the Mathematical Aspects of Emotion
Authors: Yabu Takuya
Published: December 2022

I defined emotions mathematically and examined what kind of conclusions can be obtained from the definitions from a mathematical aspect. I defined the magnitude of a certain emotion and its rate of change over time, derived the resulting partial differential equation, and derived the solution. In addition, we derived the probability distribution and probability density function of emotions when the number of emotions processed is ∞, and showed that it is a random walk discretely. Finally, I described the characteristics obtained when emotion processing is a random walk, and showed what happens in actual emotional changes. As a result, it was shown that the actual phenomenon could be expressed. I was able to express the actual phenomenon of emotions, which have been treated statistically, from a few mathematical definitions.

Published: December 2022

When developing a variety, along with the classical breeding methods, there are increasingly being used bio-technological and molecular genetic methods. These methods include a cultivation technology of isolated anthers, based on the phenomenon of androgenesis. The current paper has presented the results of developing androgenetic rice lines from 7 hybrids of the first generation. The purpose of the work was to study the ability of rice hybrids to form callus on artificial nutrient media and develop regenerated plants followed by a visual estimation of ploidy. Developing dihaploid homozygous lines will speed up the breeding process. The selection of rice panicles was carried out in the field in the shooting phase at the stage of mononuclear pollen. There were cultivated 7218 anthers, of which there were obtained 259 calli. The combinations ‘Akustik x Nerica 1’, ‘Nerica 1 x Akustik c’, ‘Kapitan x Akustik’ were the most responsive to callus formation. The regeneration frequency to the number of calli was 9.13 %. There were identified 794 new formations, from which there were formed 46 plants, including 26 albino and 20 green. The largest number of plants was formed in the hybrid ‘Kapitan x Akustik’ (22 pcs., 14 of which are green). Among the survived green regenerated plants, according to a complex of morphological traits, two plants turned out to be haploids with small sterile flowers and anthers, thin and narrow leaves; five plants were dihaploids with well-grained panicles and medium-sized leaves; two plants were tetraploids that had a wide leaf, a large panicle with very large flowers, but with low fertility. Plants and seeds were handed over to breeders for further work.

The current paper has presented the study results of the elements of cultivation technology (sowing date, sowing method, seeding rate) of grain sorghum in the southern part of the Rostov region. Field trials were carried out in 2018–2020. The object of research was the grain sorghum variety ‘Zernogradskoe 88’, included in the State List of Breeding Achievements for the North Caucasus region in 2013. According to the study results there was established that the lowest values of grain weight per plant and 1000-grain weight were formed with a seeding rate of 0.9 million of germinating seeds per ha.In the same variant of the trial, there was determined theworst plants’ preservation before harvesting. Sowing method had the greatest effect on plant density (69.5 %) and on 1000-grain weight (23.8 %); seeding ratehad the greatest effect on grain weight per plant (52.5 %). On average, through the years of study, there was obtained the maximum productivity of 4.14 and 4.12 t/ha with a seeding rate of 0.4 and 0.5 million of germinated seeds per ha, respectively. For grain sorghum, the sowing method with a row spacing of 0.15 and 0.30 m was the most acceptable, where there was yielded 3.70 and 3.65 t/ha. When sowing seeds in the 3rd decade of May (20–22 °C of warming up the soil at a seeding depth), there was identified a maximum productivity of sorghum grain with 3.92 t/ha. The greatest effect on productivity formation (41.6 %) was produced by the seeding rate, the share of the effect of the sowing date was 24.8 %, that of the sowing method was 3.6 %, weather conditions affected on 7.7 %.

Authors: CAN Yusuf , AKSOY Mehmet Akif , AKSOY Esra , NARLI Serkan
Published: December 2022

The number and variety of educational mathematics mobile applications (EMMAs) make it difficult to select mobile applications for mathematics learning and teaching. Therefore, in this study, multi-criteria decision-making (MCDM) techniques, which are effectively used in a wide variety of disciplines, were applied to choose among alternative applications according to specified criteria. In this context, it was aimed to determine which of the 13 considered EMMAs that work on Android-based tools and were proposed by experts according to certain features were most effective with the help of the TOPSIS algorithm, one of the popular MCDM methods. The results obtained from an evaluation using 10 criteria (4 evaluator-independent, 6 evaluator-dependent) were analysed with MATLAB.

In today's world, where the accessibility of information is increasing thanks to the development and transformative effect of technology, the use of technology in the education system is now indispensable. The use of technology in the learning experiences of students, who are defined as digitally native in particular, has facilitated both the design of activities more appropriate for their learning habits and the application of contemporary methods based on the constructivist approach. The pandemic process has increased the application of constructivist methods and the importance of research on these methods in order to increase the quality of distance education. In this context, the effect of the mobile assisted online flipped learning experience on pre-service teachers' information literacy skills and their educational beliefs was examined. A total of 74 pre-service teachers studying in the first year of the Guidance and Psychological Counseling Department of Tokat Gaziosmanpaşa University, Faculty of Education, participated in the study, which was carried out in a four-week period. The research was conducted with the quasi-experimental design with pretest-posttest control group. In the study, the pre-service teachers in the experimental group taught the selected topics within the scope of the Instructional Design course online through the mobile assisted flipped learning model, while the pre-service teachers in the control group taught the same topics online through the leacture-based instruction model. Before and after the process, measurement tools were applied to both groups, and the differences between and within groups were evaluated. In addition, by conducting a focus group interview with the pre-service teachers in the experimental group, their experiences about the process were tried to be understood in depth. As a result of the research, it was determined that the flipped learning model is also an effective method in the distance education process, and the course conducted through the mobile assisted online flipped learning model contributes to the increase of the information literacy level and edicational beliefs by improving the different skills of the pre-service teachers.
Thoracic spinal angiomyolipoma: case report from an Ethiopian neurosurgical teaching hospital. Illustrative case
Authors: Laeke Tsegazeab , Yibeltal Mestet , Kwon Young Dae
Published: December 2022

BACKGROUND

Angiomyolipoma (AML) of the spine is a rare benign neoplasm (accounting for 0.14%–1.2% of all spine tumors) that is often described along with angiolipoma because of their similarities. They occur almost exclusively in the extradural space, with the thoracic spine being the commonest level.

OBSERVATIONS

The authors present the clinical presentation, diagnosis, and treatment of an extremely rare case of thoracic spine AML in a 47-year-old male patient. The patient underwent laminectomy and gross total resection of the tumor and had an excellent immediate postoperative neurological recovery and long-term functional neurological outcome.

LESSONS

It is always wise to consider rare benign spinal epidural neoplasms such as spinal AMLs in the differential diagnosis of spinal epidural mass, despite metastasis being the commonest epidural tumor with variable modes of treatment, because the management of benign spinal epidural masses such as spine AML is always surgical and associated with an excellent long-term outcome.
Safety and efficacy of salvage therapy with laser interstitial thermal therapy for malignant meningioma refractory to cesium-131 brachytherapy: illustrative case
Authors: Yudkoff Clifford , Mahtabfar Aria , Piper Keenan , Judy Kevin
Published: December 2022

BACKGROUND

Anaplastic meningioma are rare, cancerous tumors of the central nervous system that often require multimodal therapy for tumor control. Both laser interstitial thermal therapy (LITT) and brachytherapy with implanted cesium-131 metallic seeds have demonstrated efficacy in the treatment of recurrent and resistant anaplastic meningioma; however, their safety as a dual therapy has never been reported.

OBSERVATIONS

In this report, the authors present a case of a 53-year-old female who received LITT in combination with brachytherapy after surgical and radiation treatment options had been exhausted. The authors discuss the unique safety concern of thermal injury with this treatment combination and demonstrate their method for the safe administration of these treatments together. Furthermore, the authors provide a review of the literature on LITT as an emerging therapy for anaplastic meningioma.

LESSONS

The use of LITT in combination with brachytherapy remains an option for salvage therapy in patients with recurrent meningioma that provides durable local control of tumor.

Published: December 2022

Abstract: The problem of virtual sensors design in linear and nonlinear systems is studied. The problems is solved in three steps: at the first step, the linear model invariant with respect to the disturbance is designed; at the second step, a possibility to take into account the nonlinear term and to estimate the given variable is checked; finally, stability of the observer is achieved. The relations allowing to design virtual sensor of minimal dimension estimating prescribed component of the state vector of the system are obtained. The theoretical results are illustrated by practical example.

Published: December 2022

The prevalence of arterial hypertension is reaching alarming proportions in low- and middle-income countries, including Ukraine. A sufficiently high prevalence of hypertension among people of the working age creates an additional economic burden on the country's budget.

Domestic and international clinical guidelines for the treatment of hypertension recommend to prefer using the combinations of drugs from different groups for the treatment of hypertension. Fixed combinations provide additional benefits for patients and healthcare programs, including simpler dosing regimens, improved adherence and better blood pressure control.

The aim of this research was to analyze the dynamics of changes in the range of fixed combinations of antihypertensive drugs registered at the pharmaceutical market of Ukraine in 2022 compared to 2015.

The object of the research was the data of the State Register of Medicinal Products of Ukraine for 2015 and 2022. The research was conducted using modern methods of analysis, systematization and generalization, mathematical and statistical calculations.

According to the results of the retrospective analysis it was established that the total number of registered drugs increased by 28%. During the analyzed period, the assortment of the domestic market was supplemented with new combinations of antihypertensive drugs, which contribute to the qualitative and quantitative expansion of the assortment of combined antihypertensive drugs.

In the analyzed period, there was a tendency to increase the share of medicines containing a fixed triple combination of active substances, which have antihypertensive effect, from 5.8% in 2015 to 13.6% of the assortment in 2022.

The analysis of the assortment structure of combined antihypertensive drugs made it possible to establish a significant dominance of two groups, namely, angiotensin II receptor blockers in combination with diuretics (almost 27% of the assortment) and angiotensin-converting enzyme inhibitor with diuretics (from 36.1% to 20% of the assortment).

According to the analysis, the dominance of foreign medicines at the pharmaceutical market of Ukraine was established. In 2015, the share of Ukrainian manufacturers was 26.45%, but the expansion of the range of drugs in the period until 2022 was provided by foreign manufacturing companies, which led to decrease in the share of domestic drugs to 17.3%.

The analysis of the domestic market of combined antihypertensive drugs showed significant saturation and increase in the depth of the product range in the period to 2022. Nevertheless, it also made possible to establish the feasibility of creating and developing domestic combined antihypertensive drugs.
