Equilibrium Analysis of Unfair Competition from Shoddy Goods: The Role of Consumer Behavior
Authors: Hu Shu , Wu Tong
Published: June 2024

Advances in e-commerce allow consumers to learn the truth about shoddy goods. This paper develops an analytical framework~-- for examining the competition between an honest manufacturer (the ''truth-teller'') and a deceptive manufacturer (the ''deceiver'')~-- that incorporates three aspects of consumer behavior:\ perceived utility, negative word-of-mouth (WOM), and aversion. Our equilibrium analysis suggests that a truth-teller's lowered production cost can reduce deception-related losses by discouraging the deceiver from excessively improving its product quality; however, the truth-teller's own excessive improvement of product quality would actually benefit the deceiver when consumers (wrongly) perceive the deceiver's products to be of high quality. Finally, a truth-teller can deal with a deceiver's unfair competition by facilitating the dispersion of early-bird consumers' negative WOM and/or by increasing late-arriving consumers' aversion to deception beyond a certain threshold. Otherwise, the truth-teller should notice that increased dispersion and aversion will give the deceiver a free ride on his reduced production cost. In particular, if the consumer response to deception~-- a combination of the dispersion of negative WOM and the aversion to deception~-- is weak, then the truth-teller always has an incentive to prevent the deceiver from excessively exaggerating its product quality by lowering his production cost; then the truth-teller's deceiver-induced profit loss would be reduced. However, if the consumer response to deception is strong, though the truth-teller can completely prevent the deceiver from exaggerating its product quality by raising his own production cost, he might not have sufficient incentive to do so since this strategy would reduce his own profit.

Purpose:
The study investigated microRNA-152-3p-mediated autophagy and sensitivity of paclitaxel-resistant ovarian cancer cells.
Methods:
The miR-152-3p mimics and miR-152-3p inhibitor were transfected in A2780 cells and A2780T cells, and the scrambled sequences were transfected as a negative control group, the transfection efficiency was detected by qPCR technology. MTT was used to detect the proliferation and IC50 value of the cells after transfection. The expression of target proteins in A2780 cells and A2780T cells were detected by qPCR; The expression of phosphatase and tensin homolog (PTEN) and ATG4D after transfection were analyzed by Western blot. The knockdown efficiency of PTEN was detected by reverse qRT-PCR, MTT and Western blot.
Results:
The expression level of miR-152-3p in A2780T cells was 52-fold higher than that in A2780 cells according to the results of qPCR. Downregulation of miR-152-3p reversed PTX-induced autophagy, inhibited cell proliferation and apoptosis, and reduced drug resistance in A2780T cells. Moreover, PTEN appeared to be potential targets of miR-152-3p, and low expression levels of miR-152-3p increased PTX sensitivity by downregulating PTEN in vitro.
Conclusion:
PTEN may be a novel therapeutic target gene for patients with PTX-resistant ovarian cancer.

Authors: Du Zhuman , Chen Xiaoju , Chen Pei
Published: June 2024

Mycoplasma pneumoniae is a common pathogen of community-acquired pneumonia, exhibiting a periodic epidemic pattern. However, there is currently no research comparing the characteristics of co-infections in patients with Mycoplasma pneumoniae. This study aims to explore the epidemiological characteristics of co-infections associated with Mycoplasma pneumoniae and to assess the specific traits of laboratory findings utilizing targeted Next-Generation Sequencing (tNGS) technology. A total of 104 patients diagnosed with Mycoplasma pneumonia were included. Based on the results of targeted NGS testing, patients were divided into a group with pure Mycoplasma pneumoniae infection (46 cases) and a group with Mycoplasma pneumoniae co-infected with other bacterial infections (58 cases). Data regarding demographic characteristics, laboratory tests, and targeted NGS results from bronchial lavage fluid during hospitalization were collected. Patients with pure Mycoplasma pneumoniae infection exhibited significant differences in lymphocyte count, neutrophil-to-lymphocyte ratio, alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) levels compared to those with Mycoplasma pneumoniae complicated by other infections (P < 0.05 for all). The rate of pure Mycoplasma pneumoniae infection was higher in females than in males (P < 0.05). Older patients were more prone to pure Mycoplasma pneumoniae infection, whereas younger patients were more likely to have Mycoplasma pneumoniae complicated by bacterial infections (P < 0.05 for both). Furthermore, Streptococcus pneumoniae was the most common pathogen associated with co-infections, particularly prevalent among children (P < 0.05). There are differences in age, gender, and laboratory test results between patients with pure Mycoplasma pneumoniae infections and those with Mycoplasma pneumoniae coinfections, with varying infection characteristics displayed among patients of different age groups.

Published: June 2024

To assess nutritional status of patients with type 2 diabetes and analyze the risk factors by using 4 nutritional assessment tools in The Second Affiliated Hospital of Chongqing Medical University.This study involved 421 patients with type 2 diabetes hospitalized in The Second Affiliated Hospital of Chongqing Medical University between August 2022 and February 2023. Four nutritional assessment tools, including the GLIM, NRS-2002, MUST, and MNA-SF were used to assess nutritional status to the patients with type 2 diabetes. The multivariate logistic regression analysis method was used to identify the risk factors of nutritional status. The 421 patients has 252 (59.9%) males and 169 (40.1%) females, with the mean age of 58 ± 15 years, the median BMI of 24.7±3.8. The incidence of malnutritionnutrition risk were 12.8%, 22.1%, 30.4% and 33.3% for the GLIM, NRS-2002, MUST and MNA-SF tools, respectively. Compared with the well-nourished patients, the malnutrition patients show the significant differences in the aspects of the BMI, Barthel index, education level, sex, smoking, duration of diabetes, complication and medical insurance (P<0.05). After adjusting for confounding factors, the multivariate logistic regression analysis indicated that the BMI (odds ratio (OR) = 0.841, 95% CI = 0.769 - 0.919), sex (OR = 0.539, 95% CI = 0.301 - 0.967 ), duration of diabetes (OR = 0.955, 95% CI = 0.915 - 0.997 ), smoking (OR = 1.996, 95% CI = 1.089 - 3.657 ) might be the independently factors of nutritional status. Excluding the BMI from multivariate logistic regression analyze, the results showed that the Barthel index, education level (OR = 0.53, 95% CI = 0.286 - 0.981), sex (OR = 0.478, 95% CI = 0.272 - 0.843) were independent factors for malnutrition in T2DM patients (all P < 0.05). Excluding BMI again for confounding factor analysis, the multivariate logistic regression analysis indicated that Barthel index, education level (OR = 0.53, 95% CI = 0.286 - 0.981), sex (OR = 0.478, 95% CI = 0.272 - 0.843) were independent factors for malnutrition in T2DM patients (all P < 0.05). We shouldn’t ignore the prevalence of malnutrition in hospitalized patients with type 2 diabetes. The BMI, Sex, Duration of diabetes, smoking, Barthel’s index and Education level were independently associated with malnutrition. We recommend to prevent malnutrition in type 2 diabetes by controlling the influenced factors above.

This study addresses gaps in research on the pore structures of deep, organic-rich marine shales, focusing on the lower Silurian Longmaxi Formation in Sichuan's Luzhou Block, using wells L1 and L2. Employing techniques like organic geochemistry, mineral composition analysis, CO2 and N2 adsorption-desorption, high-pressure mercury intrusion, FIB-SEM, and NMR, the study identifies pyrobitumen as the main pore contributor, accounting for approximately 59.95%-62.00% of pores. It documents a reduction in pore storage and connectivity from the over-mature to semi-graphitised stages, with mesopores showing a smaller decline (8.37%-9.14%) compared to micropores and macropores (25.02%-52.86%). Additionally, connectivity of 100–1000 nm pores decreased significantly (33.46%-62.09%). Changes in the stages of maturity affected the pore characteristics: retained oil in mature stages transformed into pyrobitumen, reducing surface porosity. In the over-mature stage, diagenesis and thermal evolution led to gas-filled pyrobitumen pores which balanced with formation pressures to preserve pore structure. The semi-graphitised stage saw a significant reduction in pore volume and surface porosity due to compaction and carbonization.

Published: June 2024

In recent years, the provision of drinking water and health to the residents of the holy metropolis of Mashhad has become the main concern of the decision makers of this basin. In this regard, one of the suggested ways to compensate part of the shortages of water demand for drinking and sanitation in the city of Mashhad is the plan to transfer water from the Chechehe and Qaretikan dams by constructing structures downstream of these dams and transferring the water to the water transfer tunnel of the Dosti Dam and then to the city of Mashhad. For this purpose, in this study, first, the changes in water allocation from these two dams were evaluated by taking into account drinking, agricultural, ecological needs and the water treaty between Iran and Turkmenistan using the WEAP water allocation model. Then, in the second stage, the assessment of meeting the above-mentioned needs was investigated using the Water supply percentage index. According to the results, the transfer of water due to the threshold of limit transferable volume, is practical and possible. However, it should be noted that no additional loading should be considered during the wet periods as compared to the existing conditions in order to ensure a stable supply of drinking water in Mashhad through two dams.
Performance of the structural damage detection of composite fibre concrete using (EMI) Technique with piezoelectric sensor
Authors: Sonker Maheshwari , Shanker Rama
Published: June 2024

Composite structures and materials find widespread applications across industries such as civil engineering, automotive, and aerospace owing to their exceptional strength-to-weight ratio, stiffness, and resistance to corrosion. However, these materials are prone to various forms of damage, including matrix cracking, delamination, and fiber breakage, which can compromise their performance and lead to failure. Hence, the development of robust health monitoring and inspection (HMI) techniques is imperative for the multi-damage detection and durability assessment of composite structures and materials. Electromechanical impedance (EMI) emerges as a promising HMI technique for such applications. EMI, a non-destructive testing (NDT) method, involves measuring the electrical impedance of a piezoelectric sensor bonded to the structure, enabling detection and characterization of damage. In this study, standard cube specimens were cast using OPC cement, Class F fly ash, and polypropylene fiber mixture. Analysis revealed a direct correlation between the Root Mean Square Deviation (RMSD) index and crack dimensions, with heightened sensitivity observed at smaller patch-to-damage distances. Moreover, the conductance and susceptance signatures consistently shifted with increasing damage, with significant leftward shifts indicating damage severity. A new damage index, ranging from 0 to 1, facilitated quantitative damage analysis, exhibiting pronounced variation in the 30–400 kHz frequency range. Additionally, equivalent stiffness and damping structure parameters were evaluated. Overall, the research demonstrates the effectiveness of surface piezoelectric sensors based on the EMI technique in monitoring concrete damage and its evolution, providing valuable insights for predicting the service life and durability of concrete structures.

Reproducible and scalable fabrication of two-dimensional (2D) materials within standard laboratory and industrial facilities has brought remarkable advancements and perspectives in both scientific and industrial domains. As the trajectory towards the graphene era continues, there is a compelling need to harness 2D technology further for the transformation of three-dimensional (3D) materials production and applications. Here, we resolve this challenge for one of the most widely utilized 3D material in modern electronics – gold – using graphene-inspired fabrication technology that allows us to develop a multistep production method of quasi-2D gold films. Such films demonstrate exceptional properties – continuous morphology, low sheet resistance (10 Ω/sq), and high transparency (80%), offering unprecedented opportunities in a variety of technological and scientific sectors. To this end, we demonstrate smart contact lenses and thermal camouflage based on 2D gold. Technologically, the record-breaking characteristics of ultrathin gold films open new horizons for the next-generation flexible and transparent electrodes for photonics and optoelectronics. Most importantly, the demonstration of 2D gold changes the very paradigm of the field of 2D crystals and dramatically expands the range of available 2D materials.
Vaccination Games of Boundedly Rational Parents toward New Childhood Immunization
Authors: Yin Wei , Ndeffo-Mbah Martial L , Oraby Tamer
Published: June 2024

Infectious diseases harm societies through disease-induced morbidity, mortality, loss of productivity, and inequality. Thus, controlling and preventing them is critical for public health and societal well-being. However, societies can hamper efforts to control the spread of diseases by non-adherence to public health recommendations; like, through vaccine hesitancy. Various disease-transmission models have been utilized to help policymakers respond to (re)emerging outbreaks. The usefulness of such models in assessing the effectiveness of public health policies is significantly dependent on human behavior. This paper introduces a new model of parental behavior toward a new childhood immunization. The model incorporates societal features, social norms, and bounded rationality. We integrate that model with the dynamics of childhood disease depicted by a standard susceptible-infected-recovered model to offer a detailed perspective on vaccine acceptance dynamics. We found that the behavioral model provides a new population game theory's replicator dynamical equation with an entropy-like term. Interestingly, societal norms and bounded rationality play an important role in shaping vaccine uptake through a new function, which we call the critical societal vaccine cost. The results suggest that reduced vaccine costs below that critical societal vaccine cost and higher initial acceptance rates increase the probability of disease elimination. A gradual increase in the cost of vaccination as an adaptive dynamical policy of disease eradication is also possible. In particular, strong social norms and low levels of bounded rationality positively contribute to disease eradication even when the basic reproduction number of the disease in that society is large.

Authors: ilyes HABIA Mohamed , Aissa Manallah , Khaled Ayadi
Published: June 2024

Recent scientific and technical advancements have resulted in the creation of very sensitive biosensing devices for pathogen detection. Surface plasmon resonance (SPR) has developed as an environmentally benign and effective label-free detection method in clinical research, notably for studying biomolecular interactions such as hemoglobin interactions. SPR can be used to assess blood abnormalities such as anemia, which is characterized by a transitory fall in blood hemoglobin concentration due to a decrease in red blood cell count. When compared to gold film sensors, using silver as the metal material and graphene to improves the sensitivity and gives a more distinct reflectance spectrum. The fundamental goal of this research is to improve hemoglobin detection sensitivity by concentration analysis, hence leading to a better knowledge of blood behavior utilizing SPR. This entails examining SPR reflectivity and calculating electromagnetic field dispersion in multilayer structures using a mechanism for wave propagation in stratified media based on transfer matrices.

Kıymetli evrak hukukunda iş ve tatil günlerinin belirlenmesi kambiyo senetleri bakımından büyük bir önem arz etmektedir. Zira kanun koyucu, poliçede kabul için ibraz ve kabul etmeme halinde kabul etmeme protestosu düzenleme veya poliçe ve bonoda ödeme için ibraz ve ödememe halinde ödememe protestosu düzenleme için belirli zamanlar öngörmüş ve öngörülen bu zamanların tatil günlerine rastlaması ihtimalinde sorunun çözümüne yönelik 6102 sayılı Türk Ticaret Kanunu’nda (TTK) hükümler tahsis etmiştir. Ayrıca çekin ödenmesi için ibraz edilmesi yahut ödenmemesi durumunda ödenmeme durumunun tespitinin protesto ile yapılması hali için öngörülen tarih, tatil gününe denk gelmişse, tıpkı poliçe ve bonoda olduğu gibi sorunun çözümüne ilişkin TTK’de düzenlemelere yer verilmiştir. Ancak TTK ve diğer mevzuat hükümleri incelendiğinde iş ve tatil günlerini ilgilendiren hükümler arasında uyumlu bir bütünlük olmadığı göze çarpmaktadır. İşte bu sebeple kıymetli evrak hukuku bakımından iş ve tatil günlerinin saptanması önemli bir sorun teşkil etmektedir. Bu çalışmada kıymetli evrak hukuku çerçevesinde iş ve tatil günlerine ilişkin TTK ve diğer mevzuat hükümleri ele alınmış, konu hakkındaki Yargıtay kararlarından bahsedilmiştir.

Published: June 2024

Effective water resource management in gauged catchments relies on accurate runoff prediction. For ungauged catchments, empirical models are used due to limited data availability. This study applied artificial neural networks (ANNs) and empirical models to predict runoff in the Bhima River basin. Among the tested models, the ANN-5 model, which utilized rainfall and one-day delayed rainfall as inputs, demonstrated superior performance with minimal error and high efficiency. Statistical results for the ANN-5 model showed excellent outcomes during both training (R = 0.95, NSE = 0.89, RMSE = 17.39, MAE = 0.12, d = 0.97, MBE = 0.12) and testing (R = 0.94, NSE = 0.88, RMSE = 11.47, MAE = 0.03, d = 0.97, MBE = 0.03). Among empirical models, the Coutagine model was the most accurate, with R = 0.82, MBE = 74.36, NSE = 0.94, d = 0.82, KGE = 0.76, MAE = 70.01, MAPE = 20.6%, NRMSE = 0.22, RMSE = 87.4, and DRV = −9.2. In contrast, Khosla's formula (KF) significantly overestimated runoff. The close correlation between observed and ANN-predicted runoff data underscores the model's utility for decision-makers in inflow forecasting, water resource planning, management, and flood forecasting.

Carcinoma after Ultrasound-guided Microwave Ablation
Authors: Wang Xinyao , Gu Dongyue , Qin Haiying , Lu Xiao , Hu Jingxi , Zhang Huan , Wan Xiaoqi , He Guangbin
Published: June 2024

Background::

Ultrasound-guided microwave ablation (MWA) is recommended as a first-line treatment for early liver cancer due to its minimally invasive,
efficient, and cost-effective nature. It utilizes microwave radiation to heat and destroy tumor cells as a local thermal therapy and offers the benefits
of being minimally invasive, repeatable, and applicable to tumors of various sizes and locations. However, despite the efficacy of MWA, early
recurrence after treatment remains a challenge, particularly when it occurs within a year and has a significant impact on the prognosis of the
patient.

Objective::

This study aimed to identify the risk factors for early recurrence after MWA in patients with hepatocellular carcinoma (HCC) and establish a predictive model.

Methods::

A total of 119 patients with hepatocellular carcinoma (HCC) treated in the Department of Ultrasound at the First Affiliated Hospital of the Air
Force Medical University from January, 2020 to April, 2022 were included in this study. Patients were categorized into the early recurrence group
and the non-early recurrence group based on whether recurrence occurred within 1 year. We conducted univariate analysis on 29 variables. A
predictive model was developed using multiple-factor logistic regression analysis, and a risk column graph was created

Results::

A total of 28 patients were included in the early recurrence group, with an early recurrence rate of 23%. Tumor size ≥ 3cm, multiple tumors, AST >
35 U/L, low pathological differentiation, CD34 positive, Ki67 level, quantitative parameters mean transit time (mTT), and rise time (RT) were
confirmed as risk factors affecting early recurrence after ablation (P < 0.05). Furthermore, the model constructed based on these 5 predictive
factors, including tumor size, tumor number, pathological differentiation, CD34, and quantitative analysis parameter mTT, demonstrated good
predictive ability, with an AUC of 0.93 in the training set and 0.86 in the validation set.

Conclusion::

Our research indicates that the risk column graph can be utilized to predict the risk of early postoperative recurrence in patients after MWA. This
contributes to guiding personalized clinical treatment decisions and provides important references for improving the prognosis of patients.
Bimetallic Metal-Organic Framework Decorated 3D-electrospun Nanofibers as a Highly Efficient Sorbent for Removing Organic Dyes from Contaminated Water
Authors: El-Said Waleed Ahmed , Al-Bogami Abdullah S. , Akhdhar Abdullah , Akhtar Naeem
Published: June 2024

Background:

Recently, bimetallic metal-organic frameworks (MOFs) have gained
significant attention for their potential in treating industrial wastewater. The rapid increase in
industrialization worldwide has resulted in the continual discharge of organic dyes in aquatic
ecosystems. These dyes disrupt aquatic ecosystems and are hazardous for human beings. Thus, there
is a considerable demand to design a framework for the removal of contaminants from wastewater.
For this purpose, this study focuses on synthesizing BM-MOF@PC and investigating its efficacy in
removing methyl orange (MO) and congo red (CR).

Methods:

A novel, low-cost, eco-friendly Zn and Co-based bimetallic MOF (BM-MOF) modified
polyaniline and cellulose acetate (PC) were synthesized based on electrospun (BM-MOF@PC)
nanofibers. The prepared BM-MOF@PC was characterized by SEM, XRD, FTIR, and N2
adsorption-desorption isotherm. The smooth formation of BM-MOF@PC nanofibers generates high
adsorption capability by exposing the maximal active site for the adsorption at the entire surface. The
adsorption capability of synthesized BM-MOF@PC nanofibers was evaluated against MO and CR
dyes from an aqueous phase.

Results:

The maximum adsorption capacity of MO and CR at the surface of BM-MOF@PC
nanofibers were 636.9 and 313.05 mg/g, respectively. Several adsorption parameters, including
initial dye concentration, contact time, temperature, the adsorbent's doses, and pH's effect on
adsorption kinetics, were investigated. The ability of BM-MOF@PC nanofibers to adsorb MO and
CR at various pHs indicated that several attraction forces, including electrostatic interaction,
hydrogen bonding, and π-π interactions, could be involved in the dye removal.

Conclusion:

The fabricated material BM-MOF@PC nanofibers have a large surface area compared
to BM-MOF, which indicates the more active sites for the adsorption of MO and CR dyes. Moreover,
the BM-MOF@PC nanofibers demonstrated robust reusability towards MO and CR adsorption
across five cycles, which suggested that our fabricated material is more stable and economically
reliable in real-time applications.

Therapeutic termination of pregnancy (TToP) is performed for maternal health risks or severe fetal malformations. Research focuses on women's psychopathological outcomes after TToP, noting that 10-22% of women experience psychiatric disorders, especially depressive symptoms and post-traumatic stress disorder (PTSD). However, little is known about paternal mental outcomes. This study analyzed biological fathers' mental health at a 1-year follow-up after TToP. Results indicate biological fathers show no alarming psychiatric outcomes one-year post-TToP, with no signs of PTSD. Resilience might be a protective factor, but further research is needed. Furthermore, the high percentage of paternal emotional neglect during childhood should interfere with the conclusions. Additional analysis is mandatory and it is essential to highlight that 30% of the original male sample refused to complete the questionnaires due to emotional distress in recalling. Still, their data are missing, and it is not possible to make inferences from them. However, mental health support should be offered on a regular basis to both men and women.

Authors: Vladimirov Yu. S.
Published: June 2024

The article is devoted to presentation of fundamentals of the metarelational paradigm based on metaphysical principles and aimed at joining the principles of three dualistic physical paradigms in the context of the relational approach. The problems of utmost importance, solvable in the framework of the metarelational approach are shown. Among these are: evidence of spinor description of particles in quantum electrodynamics; an algebraic formulation of the atomic theory; revealing the sources of the origin of classical space-time concepts; a new approach to justification of types and the properties of elementary particles involved in strong interactions; the relational approach to atomic nuclei structure description; the description of going from a prototype to the present concepts of classical space-time; a dualistic relational interpretation of classical physics; an approach to the nature of gravitational interactions alternative to General Relativity.

Published: June 2024

ABSTRACT – This study critically evaluates the effectiveness of Islamic governance on the financial performance of Islamic banks in Indonesia. Due to the absence of regulations defining optimal Sharia Supervisory Board (SSB) structure and qualifications, the research explores the empirical relationship between SSB characteristics and financial performance. Using a quantitative approach, the study analyzes data from 14 Islamic banks over a seven-year period (2014-2020). Multiple regression analysis reveals that SSB size, educational background, and financial/accounting expertise have minimal impact on financial performance. Interestingly, cross-membership on SSBs is found to have a negative effect. These findings, coupled with the observation of SSBs often lacking banking and finance backgrounds, suggest a potential disconnect between Sharia governance and managerial activities. The study advocates for clear and comprehensive regulations to strengthen SSB composition and competence, ultimately promoting the sustainable development of Islamic banking in Indonesia.========================================================================================================ABSTRAK – Hubungan Antara Tata Kelola Syariah dan Kinerja Keuangan: Bukti dari Perbankan Syariah Indonesia. Studi ini secara kritis mengevaluasi efektivitas tata kelola Syariah terhadap kinerja keuangan perbankan syariah di Indonesia. Mengingat belum adanya peraturan yang mengatur struktur minimum dan kualifikasi optimal Dewan Pengawas Syariah (DPS), penelitian ini bermaksud mengkaji secara empiris empiris hubungan antara karakteristik DPS dan kinerja keuangan. Dengan menggunakan pendekatan kuantitatif, penelitian ini menganalisis data dari 14 bank Islam selama tujuh tahun (2014-2020). Hasil analisis regresi berganda menunjukkan bahwa ukuran DPS, latar belakang pendidikan, dan keahlian keuangan dan akuntansi kurang memiliki dampak terhadap kinerja keuangan perbankan syariah. Menariknya, cross-membership pada DPS ditemukan memiliki efek negatif. Temuan ini, ditambah dengan pengamatan terhadap DPS yang seringkali tidak memiliki latar belakang perbankan dan keuangan, menunjukkan potensi keterputusan antara tata kelola Syariah dan aktivitas manajerial. Studi ini merekomendasikan adanya peraturan yang jelas dan komprehensif untuk memperkuat komposisi dan kompetensi DPS, yang pada akhirnya mendorong pengembangan bank syariah yang berkelanjutan di Indonesia.

This study examines the financing risk management practices of Bank Jatim Syariah, a prominent provincial-owned Islamic bank in Indonesia with total assets of IDR400 trillion, in response to the rising trend of Non-Performing Financing (NPF) in Islamic banking over the past decade. The research focuses on Bank Jatim Syariah due to its extensive service area, large customer base, and substantial financing portfolio. Employing a qualitative methodology, data was collected through interviews with the bank's financing committee and management, coupled with an analysis of pre-pandemic financing documents. The findings reveal that Bank Jatim Syariah has successfully implemented a robust NPF mitigation mechanism, including debt restructuring, debt scheduling, and both litigious and non-litigious dispute resolution strategies. These measures have effectively reduced NPF levels below 2.35%, minimized bank losses, and ensured the bank's continued ability to serve its 40 million customers in East Java. The study highlights the importance of proactive risk management strategies in maintaining the stability and growth of Islamic banking institutions.======================================================================================================== ABSTRAK – Strategi Mitigasi Risiko Pembiayaan pada Bank Jatim Syariah.

Published: June 2024

The paper is intended to provide reference material, guidance and know-how on handling, conditioning and storage of spent sealed radioactive sources (SRS) to both users of sealed sources and operators of waste management facilities. Due to the limited availability of disposal practices for spent SRS, disposal is covered in a broad context only. Aspects of handling, conditioning, and storage of spent sealed radioactive sources resulting from the use of radioisotopes and radiation sources in research, medicine, industry, and agriculture are described. The paper presents the current situation in Kosovo and Albania regarding the management of low-level radioactive waste, temporary interim storage and their system until final disposal, taking into account the IAEA documents on this topic. The methods applied for the conditioning of LLRW and SRS are simple. The important point after the inventory of radioactive waste was their location and the ID (identifying number) of the radioactive sources, based on the type of radioisotopes and their activity. The paper contains in some detail technical procedures for the conditioning of spent SRS, describes the means required to assure the quality of the resulting package and discusses the measures to prepare waste packages with a certain flexibility to accommodate possible future disposal requirements.
