Authors: Harahap Darwis , Afandi Ahmad , Siregar Try Mahendra 
Published: September 2023

This study examines factors that influence Indonesian Islamic banking customers’ behavioral intention to utilize digital banking services using the Unified Theory of Acceptance and Use of Technology (UTAUT 2). The factors examined include effort and performance expectations, social influence, facilitating conditions, price value, hedonic motivation, habits, trialability, and spiritual motivation. The study also examines whether Islamic lifestyle moderates the roles of social influence, habits, and spiritual motivation in the tendency to utilize Islamic digital banking. Gathering data from 195 Indonesian millennials and utilizing the partial least squares structural equation modeling (PLS-SEM) method, we find that not all factors have a positive effect on the propensity to utilize Islamic digital banking services. The performance expectations, social influences, price values, habits, and Islamic lifestyles all have a strong favorable effect on the desire to use digital banking. Meanwhile, the facilitating condition, hedonic motivation, trialability, and spiritual motivation only slightly affect the intention to use digital banking. Finally, the paper notes that absence of Islamic lifestyle’s moderating role.
2d Helmert and Affine Coordinate Transformation Using the Least Squares Method: Trabzon Province in Turkey
Authors: YILMAZ Nazan 
Published: September 2023

Abstract
ED50 datum uses Hayford ellipsoid and Greenwich meridian as the prime meridian. In Turkey, ED-50 datum using Hayford ellipsoid was used until 2001, and ITRF datum using GRS80 ellipsoid was used after 2001. In order to use coordinate systems in different datums, different systems must be associated and transformed to each other. In this study, 2D transformation parameters from ED-50 datum to ITRF-96 datum have been determined. For transformation, common points from both the ED-50 and ITRF systems have been selected in Maçka and Ortahisar districts of Trabzon province. The two-dimensional similarity (Helmert) and the Affine transformation methods have been applied through common points with the aim at defining the relationship between the two systems in the study area. Some statistical information has been obtained representing the sensitivity of the transformation parameters and the transformation process. In addition, test points have been selected in the study areas and the ED-50 datum coordinates of test points have been transformed to the ITRF-96 coordinates through transformation parameters. The differences between the transformed coordinates and current coordinates of these test points have been taken. The root mean square error (RMSE), minimum and maximum errors and the mean absolute errors (MAE) values have been calculated for differences. All calculations in the study have been made using the MATLAB R2022b program.

Published: September 2023

Abstract
Background
Polypoid endometriosis (PEM) is rare benign tumors with morphological features resembling malignant tumors. We aimed to analyze the clinicopathological features and outcomes of patients with PEM, and compare them to cases of endometriosis with malignant transformation.
Methods
In total 28 PEM and 44 cases of endometriosis with malignant transformation were retrospectively analyzed. Data from each of the patients was collected including clinicopathological features, treatment, and outcomes for evaluation.
Results
In the PEM group patients were aged 30 to 63 years (mean, 40.7 years). The most common clinical symptoms were pelvic mass, irregular vaginal bleeding, and lower abdominal pain. The primary sites were ovary, posterior vaginal fornix, rectum, uterosacral ligament, and abdominal incision. The PEM tumors had a median maximum diameter of 5.3 cm (IQR, 3.1–7.9). The follow-up data in the PEM group showed that 23/27 patients survived without residual disease, 3/27 patients survived with residual endometriosis, 1/27 patient survived with endometriosis-malignant low-grade endometrial stromal sarcoma (ESS). Compared with patients in the endometriosis with malignant transformation group, there were statistically significant differences in age, menopause, dysmenorrhea, adenomyosis, cancer antigen 125 (CA125) levels, and tumor size.
Conclusions
PEM is a benign lesion and has a risk of malignant transformation. Patients with PEM were younger with a smaller tumor size and a higher CA125 level when compared to patients with endometriosis with malignant transformation, which provides important information for the correct diagnosis of PEM.

Published: September 2023

Abstract
The blue-and-white porcelains from the Chinese Yuan Dynasty include different ornamentation effects, such as bow string and main patterns. In this study, ten pieces of blue-and-white porcelains from the Jingdezhen Ceramic University Museum were examined using energy-dispersive X-ray fluorescence to reveal the chemical compositions of their microzones. Three key findings were obtained. First, the Co-based material used in the specimens was imported ore with high Fe and low Mn contents, with certain amounts of Ni and As. Second, the bow-string and main patterns had different (Fe + Mn)/Co ratios; the main patterns had lower ratios, suggesting a purer Co material. Third, the differences in the elemental ratios were verified against a historical purification process, whereby the main pattern was speculated to be painted with purified Co-based materials. Finally, the material differences that began to appear during the Yuan Dynasty, which influenced the painting of blue-and-white porcelains in the Ming and Qing dynasties, were investigated. This study provides a new perspective on the blue-and-white porcelains from the Yuan Dynasty and the development of decoration systems for Chinese blue-and-white porcelain paintings.
The Role of Human Capital and Stress for Cost Awareness in the Healthcare System: A Survey among German Hospital Physicians
Authors: Lüdemann Christoph , Gerken Maike , Hülsbeck Marcel 
Published: September 2023

Abstract
Background
Germany has the highest per capita health care spending among EU member states, but its hospitals face pressure to generate profits independently due to the government's withdrawal of investment cost coverage. The diagnosis related groups (DRG) payment system was implemented to address the cost issue, challenging hospital physicians to provide services within predefined prices and an economic target corridor to reduce costs. This study examines the extent of cost awareness among medical personnel in German hospitals and its influencing factors.
Methods
Using an online survey, participants across all specialties in hospitals estimated the prices in euros of four common interventions and answered questions about their human capital and perceived stress on the workplace. As a measure of cost awareness, the probability of estimating the prices correctly within a reasonable corridor was used. We employed logit, probit, and rare events logistic regression estimators to identify influencing factors and ensure the robustness of results in a sample of 344 observations.
Results
The results revealed that most of the respondents were unaware of the costs of common interventions. General human capital, acquired through prior education, and job-specific human capital had no influence on cost awareness, whereas domain-specific human capital, that is, gaining economic knowledge based on self-interest, had a positive nonlinear effect on cost awareness. Furthermore, an increased stress level negatively influenced cost awareness.
Conclusions
This paper is the first of its kind for the German health care sector that contributes responses to the question whether health care professionals in German hospitals have cost awareness and if not, what reasons lie behind this lack of knowledge. Our findings show that the cost awareness desired by the introduction of the DRG system has yet to be achieved by medical personnel.

Published: September 2023

Abstract
Reliable techniques for successful gene transfer and propagation of plants are of central importance in basic and applied research. In maize, conventional transformation and regeneration consist of difficult, time-consuming, and cultivar-dependent procedures. To overcome these problems here, we develop a strategy to utilize an efficient, reproducible, rather simple, and cost-effective system in gene transfer to maize without any need for complicated devices. For this purpose, we explore the transformation and expression of a designed protein (LHN2F) in maize seeds using poly-ethyleneimine-coated mesoporous silica nanoparticles (PEI-MSNs) and ultrasonic treatment. The plasmid pCAMBIA3301 harboring the lhn2f and bargenes is first loaded on the PEI-MSNs and then delivered using the ultrasonic treatment to mature maize seeds. Visual screening by the herbicide and laboratory procedures involving PCR, western blotting, ELISA, and RP-HPLC were used to identify recombination events. Up to 40 % of treated seeds were grown in herbicide medium and expressed the desired protein. This methodology has the potential to become an effective tool for maize genome manipulation and editing without the involvement of any tissue culture procedure.

Published: September 2023

Abstract
Climate change is a global phenomenon that significantly impacts the ocean environment around the Korean Peninsula. These changes in climate can lead to rising sea temperatures, thereby significantly affecting marine life and ecosystems in the region. In this study, four statistical approaches were employed to analyze ocean characteristics around the Korean Peninsula: layer classification, imputation for replacing missing values, evaluation using statistical tests, and trend analysis. The ocean was first classified into three layers (surface layer, middle layer, and bottom layer) to characterize the sea area around Korea, after which multiple imputation methods were employed to replace missing values for each layer. The imputation method exhibiting the best performance was then selected by comparing the replaced missing values with high-quality data. Additionally, we compared the slope of the water temperature change around the Korean Peninsula based on two temporal inflection points (2000 and 2009). Our findings demonstrated that the long-term change in water temperature aligns with previous studies. However, the slope of water temperature change has tended to accelerate since 2009.

Published: September 2023

Abstract
In this paper a control method is proposed for a system composed of PV array, five-phase impedance source inverter, five-phase induction motor and centrifugal pump. This method is based on controlling the motor speed to control the pump power as the insolation level or temperature change to attain the maximum power extraction from the PV-array. The motor speed is controlled by using artificial neural network which is trained to provide the desired inverter frequency and modulation index at any insolation level and temperature to attain the maximum PV operating power. The data of the neural network are based on the operation of the induction motor at constant air gap flux and perturb and observe method for maximum power point tracking. Simulation results are obtained using MATLAB Simulink to verify the proposed control method.
