Comparison of Imaging Modalities in the Diagnosis and Tumor Staging of
Colorectal Adenocarcinoma
Authors: Serinsöz Serdar , Aktürk Remzi
Published: December 2022

Background:

Colorectal cancer is a malignancy that affects the gastrointestinal tract. Clinical diagnosis has routinely been done with colonoscopy in conjunction with digital rectal and histological examinations.

Objective:

We show that CT, MRI, and MRI-DWI are all effective in T-staging colorectal adenocarcinoma when compared to pathology examination. However, differences in the detection and diagnostic agreement rates between the imaging modalities for the specific T-stages were observed.

Methods:

Fifty-six patients diagnosed with colorectal adenocarcinoma and underwent contrast-enhanced abdominal CT, non-contrast MRI, or MRI-DWI between January 2014 and March 2020 were retrospectively examined and compared to a biopsy or postoperative pathological T-stage.

Results:

The total diagnostic agreement rate for CT, MRI, and MRI-DWI were 58.93%, 76.79%, and 85.71%, respectively. T-staging was statistically and significantly different across all four stages analyzed for all imaging modalities. The T1-stage for MRI and MRI-DWI compared to pathology rates were statistically significant, whereas MRI-DWI and CT both demonstrated statistical significance for T3 and T2 stage comparison, respectively. Furthermore, a statistical and significant difference between the total stage comparison of MRI, MRI-DWI, and CT compared individually to pathology was also observed. All imaging modalities were able to statistically and significantly identify tumors based on tumor size according to the ROC analysis.

Conclusion:

These data suggest that CT, MRI, and MRI-DWI can identify and aid visually in the diagnosis of adenocarcinoma colorectal cancer. MRI-DWI is more specific and sensitive in the diagnosis and staging of colorectal tumors.
Detection of Cerebrovascular Diseases using Novel Discrete Component
Wavelet Cosine Transform
Authors: Pal Bandana , Jain Shruti
Published: December 2022

Aims:

Detecting and classifying a brain tumor amid a sole image can be problematic for doctors, although improvements can be made with medical image fusions.

Background:

A brain tumor develops in the tissues surrounding the brain or the skull and has a major impact on human life. Primary tumors begin within the brain, whereas secondary tumors, identified as brain metastasis tumors, are generated outside the brain.

Objective:

This paper proposes hybrid fusion techniques to fuse multi-modal images. The evaluations are based on performance metrics, and the results are compared with conventional ones.

Methods:

In this paper, pre-processing is done considering enhancement methods like Binarization, Contrast Stretching, Median Filter, & Contrast Limited Adaptive Histogram Equalization (CLAHE). Authors have proposed three techniques, PCA-DWT, DCT-PCA, and Discrete ComponentWaveletCosine Transform (DCWCT), which were used to fuse CT-MR images of brain tumors.

Result:

The different features were evaluated from the fused images, which were classified using various machine learning approaches. Maximum accuracy of 97.9% and 93.5% is obtained using DCWCT for Support Vector Machine (SVM) and k Nearest Neighbor (kNN), respectively, considering the combination of both feature's shape & Grey Level Difference Statistics. The model is validated using another online dataset.

Conclusion:

It has been observed that the classification accuracy for detecting cerebrovascular disease is better after employing the proposed image fusion technique.
In-vitro Susceptibility Testing Methods for Ceftazidime-avibactam against
Carbapenem-resistant Enterobacterales: Comparison with Reference
Broth Microdilution Method
Authors: Sharma Bhawna , Sreenivasan Priya , Angrup Archana , Kaur Satinder , Rana Sudesh , Kundu Jyoti , Biswal Manisha , Ray Pallab
Published: December 2022

Introduction:

β-lactam antibiotics, mainly cephalosporins, and carbapenems, have been
the mainstay of treatment for infections caused by Enterobacterales. However, their role in treating
clinical infections has become limited because of the increase in resistance. There is a need to have
cost-effective and rapid methods for antimicrobial susceptibility testing methods for newer antibiotics
like ceftazidime-avibactam against carbapenem-resistant Enterobacterales (CRE), which can
be applied in routine clinical microbiology laboratories. With this aim, the present study was conducted
to compare the disk diffusion and gradient diffusion, i.e., the E-test method with the reference
broth microdilution (BMD) method for in-vitro testing of ceftazidime-avibactam against
CRE.

Material and Methods:

A total of 111 CRE isolates from various clinical samples were included.
Conventional PCR (Polymerase Chain Reaction) was done for the detection of genes encoding
carbapenemases and to see their expression, modified carbapenem inactivation method (mCIM)
along with EDTA (Ethylenediaminetetraacetic acid) carbapenem inactivation method (eCIM) was
done.

Results:

42.3% (47/111) isolates were resistant to ceftazidime-avibactam by the standard broth microdilution
method; however, 45.9% (51/111) were resistant by both disk diffusion and E-test. In
5.4% of isolates (similar in both methods), microbroth dilution method results did not match with
E-strip and disk diffusion. Very major errors (VME) by both disk diffusion and E-test were found
in 2.1% (1/47), and major errors (ME) were found in 7.8% (5/64) isolates (similar isolates in both
methods). The overall categorical agreement (CA) rate was 94.6% for both E-test and disk diffusion,
and the essential agreement (EA) rate was 90.1% (100/111) for E-test. 98% (109/111) of CRE
harbored carbapenemase genes either singly (30.3%) or in combination with others (69.7%).

Conclusion:

In conclusion, for CRE, E-test and the disk diffusion method for ceftazidimeavibactam
depicted an acceptable performance as an alternative to the reference broth microdilution
method.
Hyponatremia Related to Neurocritical Care: Focus on Diagnosis and
Therapy: A Systematic Review
Authors: Mezzini Gianluca , Marasco Stefano , Bertuccio Alessandro , Savioli Gabriele , Piccolella Fabio , Racca Fabrizio , Barbanera Andrea , Vitali Matteo
Published: December 2022

Introduction:

Hyponatremia is the most frequently occurring electrolyte disorder in
neurocritical care and traumatic brain injury, aneurysmal subarachnoid hemorrhage (SAH),
neurosurgery, and ischemic stroke are the clinical conditions more often associated with this
condition. SIADH and CSWS are the main causes of hyponatremia in neurologically ill patients.
Since hyponatremia is a negative prognostic factor for neurocritical patients, early diagnosis and
consequent targeted therapy are of fundamental importance. The present review was carried out
to provide a brief recap on the main causes and management of hyponatremia in the neurocritical
patient.

Methods:

A methodical search of the medical literature using the online database MEDLINE was
carried out and studies comprising case reports, prospective and retrospective observational
studies, or randomized controlled clinical trials in which there is a diagnosis of hyponatremia in
neurocritical patients were included.

Results:

18 articles were analyzed, consisting of 8 case reports, 4 case series, 3 prospective trials,
1 retrospective study, and 1 multicenter trial. A total of 1371 patients from 18 studies were
included. Patients’ average age was 29.28 ± 20.9, respectively. TBI was the main cause of
hyponatremia in the literature reviewed; 12 studies were about the relationship between TBI and
hyponatremia, 2 studies about stroke, 2 studies about SAH and 1 about hyponatremia postneurosurgical
procedure.

Discussion:

Hyponatremia is the most common electrolyte disorder in hospitalized patients and
the main scenarios of hyponatremic neurocritical patients are subarachnoid hemorrhage, ischemic
stroke, traumatic brain injury and iatrogenic hyponatremia due to neurosurgical cases.

Conclusion:

Hyponatremia is a frequent finding in neurocritical care and is also a recognized
negative prognostic factor leading to increased mortality and ICU length hospitalization. Its
diagnosis and therapy are essential for correct neurocritical management. The most common
cause of serum sodium abnormality is SIADH, and an early diagnosis for target treatment is
paramount to prevent delayed symptoms and complications.

Nonalcoholic Fatty Liver Disease
Authors: Jia Jue , Yuan Guoyue , Wang Zhaoxiang , Xia Yue , Pan Yi , Zhang Li , Tang Fengyan , Yu Xiawen , Yang Zhongming , Wang Dong , Yang Ling
Published: December 2022

Background:

Immune cell infiltration is an important component of nonalcoholic fatty
liver disease (NAFLD) pathogenesis. This study aimed to explore novel genes associated with immune
infiltration in the progression of NAFLD.

Methods:

CIBERSORT was used to evaluate the abundance of immune infiltration in the human
NAFLD via a high-throughput sequencing dataset. Further weighted gene co-expression network
analysis (WGCNA) was performed to search for the susceptibility gene module and hub genes
associated with differential immune cells. The expression of hub genes in different liver non-parenchymal
cell clusters and NAFLD-associated hepatocellular carcinoma (HCC) was also explored.

Results:

Four hub genes (ITGBL1, SPINT1, COL1A2, and THBS2) were ultimately identified,
which may be associated with immune infiltration, fibrosis progression, and activity score. The
receiver operating characteristic curve (ROC) analysis suggested that these genes had good predictive
value for NASH and advanced fibrosis. A single-cell analysis showed that COL1A2 was highly
expressed in hepatic stellate cells (HSCs), especially in the later stage, while SPINT1 was highly
expressed in cholangiocytes (Cho). In addition, ITGBL1, COL1A2, and THBS2 might be associated
with transforming from nonalcoholic steatohepatitis (NASH) to HCC. Our findings identified
several novel genes that might be related to immune infiltration in NAFLD.

Conclusion:

These genes may serve as potential markers for the assessment of immune infiltration
as well as therapeutic targets for NAFLD. More studies are needed to elucidate the biological mechanism
of these genes in the occurrence and development of NAFLD.

Authors: Naseef Hani , AbuKhalil Abdallah  Damin , Orabi Tala , Joza Mohammad , Mashaala Carmen , Elsheik Malak , Dababat Aseel , Qattosa Maram , Al-Shami Ni'Meh , Rabba Abdullah K
Published: December 2022

Background

During the COVID-19 pandemic, off-label medication prescribing and utilizing herbal products and multiple vitamins in the treatment, prevention, and symptom management of COVID-19 was an urgently needed practice to halt the SARS-Cov2 infection crisis and progression.

Objectives

This study aimed to determine the correlation between medications used during the pandemic and SARS-CoV-2 infection post-recovery symptoms.

Methods

A cross-sectional questionnaire-based study was conducted on recovered COVID-19 patients. There were 20 multiple-choice questions, including patient demographics, treatment, and post-recovery symptoms. Chi-square and Fisher’s exact tests were used to investigate significant relationships. In addition, Binary logistic regression was performed to determine confounders. Data were analyzed using SPSS version 22.

Results

Medications and supplements varied in their therapeutic effects on SARS-CoV-2 post-recovery symptoms. Patients who took vitamin D and calcium experienced increased symptom frequency, and patients taking ACE inhibitors experienced more headaches and coughs. Furthermore, more patients receiving azithromycin were asymptomatic after recovery. Patients who took H2 antagonists reported persistent headaches and muscle pain.

Conclusion

Patients infected with SARS-CoV-2 have responded differently to medications, multivitamins, and herbal supplements. Patients reported resolution of some symptoms and persistence of others post-recovery. Therefore, expert opinion should be considered in covid-19 management until randomized controlled trials answer many questions and determine medications' safety and efficacy in prevention, treatment strategies, and symptoms of SARS-Cov-2 Infection post-recovery.
Prediction of Household Food Security Status using Ensemble Learning Models
Authors: Nigus Mersha , H.L. Shashirekha
Published: December 2022

Background:

This research uses the Ethiopian HICE survey dataset. Predicting food insecurity is critical in presenting the household's situation to the appropriate agencies that take preventative and intervention measures.

Objective:

This research paper's primary goal is to predict households' food security status using ensemble learning models.

Methods:

We use five base classifiers and a voting strategy for ensemble classification to enhance the performance of different base classifiers. Backward feature elimination and hard and soft voting-based ensemble learning are used to evaluate household food security. The training set for the basic classifiers is composed of the features that have been selected. Each ML classifier makes its prediction about the class label with the help of an ensemble learning method. For making decisions, hard voting uses a simple majority, whereas soft vote employs a weighted probability. To determine the final prediction. Ethiopian household income, consumption, and expenditure dataset are used to test the proposed ensemble learning approach. The backward feature elimination approach improved the model's performance by removing irrelevant and redundant features. Random forest, gradient boosting, multi-layer perceptron, K-nearest Neighbor, and Extra Tree classifiers were used to predict the family's level of food security. Finally, the authors compare the accuracy of ensemble and base classifiers.

Result:

The experiment result shows that the RF classifier surpasses the other base and ensemble classifiers and scored 99.98% accuracy. Because a Random forest classifier is an ensemble learning classifier that uses several decision trees, the final prediction is computed based on the majority vote of the several trees. The comparison result of hard and soft voting reveals that soft voting outperforms hard voting before and after feature selection with accuracies of 99.79% and 99.77%, respectively.

Conclusion:

Based on the result obtained, ensemble learning plays a significant role in predicting household food security status and implementing hard and soft voting. The RF classifier surpasses the other base and ensemble classifiers with an accuracy of 99.98%. From ensemble methods, soft voting surpasses hard voting with an accuracy score of 99.79%.

Ceratonia siliqua L. Leaf Extracts by HPLC-ESI-MS
Authors: Meziani Saida , Oomah B. Dave , Bertrand Cédric
Published: December 2022

Background:

Olive (Olea europaea L.) and carob (Ceratonia siliqua L.), which contain considerable amounts of phenolic compounds, are the most important
nutritional and therapeutic plants in the Mediterranean basin.

Objectives:

The goal of this work is to revalue carob and olive leaves as key sources of polyphenols, hence increasing the value of waste goods.

Methods:

In this study, aqueous acetone or ethanol (80% v/v) extracts of olive (O. europaea L. cultivar aimel) and carob (C. siliqua L.) leaves from Algeria
were evaluated for phenolic content, and the extracts were characterized by reverse-phase high-performance liquid chromatography-electrospray
ionization mass spectrometry (HPLC-ESI-MS).

Discussion and Results:

The total phenolic content of olive and carob leaf extracts ranged from 5.6 to 23 mg GAE/g. The use of HPLC-ESI-MS to investigate phenolics
revealed that the extracts included a variety of phenolic compounds, including 23 compounds in olive leaf extracts and 17 compounds in carob leaf
extracts. In olive and carob, the major phenolic components are oleuropein and myricetin rhamnoside, respectively.

Conclusion:

According to our findings, olea europaea and Ceratonia siliqua appear to be rich suppliers of natural chemicals. These plants have a lot of
potential in terms of medications and functional foods.
Fetomaternal Physiology: Physiological Changes during Pregnancy
Authors: Orozco Vinasco Adriana Carolina , Álvarez Mónica San Juan , Vinasco David Orozco
Published: December 2022

Anesthesia during pregnancy is challenging due to the extreme physiological
and anatomical changes that occur. Deep knowledge of these changes and how they
influence anesthesia is critical in order to offer safe anesthetic care to both, mother and
the child. In this chapter, we will review the main features that occur in the respiratory,
cardiovascular, central nervous, renal, and gastrointestinal systems, among others, and
how it affects pharmacodynamics, pharmacokinetics, airway management and conduct
of anesthesia. Fetomaternal circulation and fetal physiology focused on anesthesia will
also be discussed.

Authors: Pinto Pilar Hernández , Doueil Marta López , Carrancho Rodrigo Sancho , Galnares Gómez Marta María
Published: December 2022

The principal goal of health systems is to provide safe and quality healthcare
for the patient. Deficiencies in the environment in which obstetric care is provided,
inadequate teamwork and communication, and poor individual performance during
emergencies have been identified as preventable causes of harm to obstetric patients.
There is growing evidence about training in Emergency Obstetric Care (EmOC) that
reduces the risk of maternal and newborn mortality and morbidity. The Institute of
Medicine identifies team-based training and simulation as methods to improve patients’
safety, especially in the obstetrics field, these may add value to it. Recent research
works review the effectiveness of training in EmOC and the use of simulation in
improved health outcomes. It remains unclear whether this translates into improved
patient outcomes.
Anesthesia for Fetal Surgery
Authors: Chacón Castillo Marta , Martos Gisbert Natalia , Orozco Vinasco Adriana
Published: December 2022

Fetal surgery has evolved in the last decades, mostly because of the
technical advances in therapeutic and monitoring devices. The timing and mode of
surgery depend on the disease to be treated. Local, neuraxial or general anesthesia can
be used on the mother. In some cases, fetal analgesia and paralysis are needed.
The idea of treating the fetus as a patient has evolved in recent years, as a consequence
of improvements in diagnostic imaging and surgical devices. In fetuses with congenital
airway obstruction, intrapartum surgical correction or airway management can be
performed while maintaining perfusion via the umbilical cord.
In 1980, maternal laparotomy and hysterotomy were proposed to treat fetuses with
congenital and developmental abnormalities, and the prerequisites for maternal-fetal
surgery were first formulated in 1982. They are still in use with some minor
modifications. A multidisciplinary approach to fetal intervention is essential. Both
obstetric and pediatric anesthesia is involved and it a close collaboration with surgical
teams is necessary.
Hypertensive Disorders in Pregnancy
Authors: Martinez Hurtado Eugenio D. , Merchante Míriam Sánchez
Published: December 2022

Due to the high risk of morbidity and mortality in pregnant women with
unrecognised and untreated preeclampsia, a high index of suspicion for signs of
preeclampsia should be used to evaluate, treat and monitor patients. Early blood
pressure control and seizure prophylaxis during labour are essential to ensure maternal
safety. However, a limited proportion of pregnancies and deliveries may present a wide
range of complications that may require admission to a critical care unit (CCU).
Hypertensive disorders of pregnancy and massive hemorrhage are among the most
common causes of admission to the CCU in pregnant and post-partum women.

Published: December 2022

The postpartum period is the time after delivery when physiological changes
by the pregnancy return to the previous state. Primary postpartum haemorrhage takes
place during the first 24 hours, and secondary postpartum haemorrhage occurs between
24 hours and 6 weeks after delivery.
Many disorders can occur in the immediate postpartum period, there is a considerable
source of morbidity and mortality in women of reproductive age, which can be mild to
severe and life-threatening.
Protocols aimed at the multidisciplinary management of postpartum haemorrhage, and
together with the use of coadjuvant hemostatic agents, the activation of massive
transfusion protocols in a responsible manner, and surgical management have improved
the prognosis of these patients.
Analgesia after Labor and Cesarean Section: Chronic Pain after Pregnancy
Authors: Gomar Sancho Carmen , Plaza Moral Ana , Vendrell Jordà Marina , López Hernández Antonio , León Carsí Irene
Published: December 2022

Chronic pain (CP) conditions after childbirth include persistent pain after
caesarean section (CPCS), perineal pain after instrumental vaginal delivery, lower back
pain and pelvic girdle pain. Any type of CP before or during pregnancy increases the
risk of CP after delivery. Scar pain is the most recognized etiology for CPCS with a
neuropathic component, although it is less frequent than in other surgeries. Reported
CPCS incidence ranges from 1 to 23%. Pain intensity is moderate and decreases with
time in all studies. The severity and duration of peripartum pain are the main risk
factors for CP and its control is the most recommended strategy for reducing risk. Fear
of fetal and neonatal adverse events means that CP is often undertreated, but after
delivery, pharmacological restrictions disappear and many pain drugs are compatible
with breastfeeding. Education of obstetric teams about early detection and referral to
specialized consultation of women with CP is the key. In this chapter, available
information in the recent literature, mainly during the last years, is presented. This
chapter focuses on CP conditions after childbirth, as analgesia for labor and childbirth
and immediate pain after CS and vaginal delivery are covered in other chapters of this
book.
Anesthetic Management for External Cephalic Version
Authors: Rodriguez María Luz Serrano , Ezquerra Sara Hervilla , Fernandez Tellez Laura , Rodriguez Esteve Andrea Alejandra , Castillo Marta Chacon
Published: December 2022

Approximately 3% to 4% of term fetuses are in breech presentation, and this
is a common indication for cesarean delivery. Twenty percent of elective cesarean
sections are due to breech position.
External cephalic version (ECV) is an obstetric maneuver that applies external pressure
to the fetal posture through the maternal abdomen, to convert a breech presentation to a
vertex presentation. Since the risk of adverse events after an ECV is small, the
possibility of ECV should be offered in all pregnancies with breech presentation,
provided that there is no contraindication.
A standardized protocol, an experienced gynecologist and adequate analgesia can
facilitate the maneuver and improve the success rate, turning the ECV into a maneuver
with an excellent safety profile which is an interesting option to avoid a cesarean
section.

Authors:   International Business Management, Faculty of Management and Business, Ciputra University Surabaya, Indonesia, Immanuel Dewi Mustikasari , Peter Yosef ,   International Business Management, Faculty of Management and Business, Ciputra University Surabaya, Indonesia
Published: December 2022

This quantitative method research aims to determine whether the product description influences purchase intention, with the mediation of enduring and situational involvement as part of platform involvement. This research is based on the Theory of Planned Behavior (TPB), Involvement theory, and previous research on product description, platform involvement, and purchase intention on online platforms. The number of samples in this study was 95 respondents, with the determination of the sample using a purposive sampling technique, with the respondent’s criteria being online consumers who had made transactions on the Tokopedia and Shopee marketplace platforms. The data analysis method is structural equation modelling Partial Least Square (SEM-PLS) with SmartPLS 3.3.7 software. The results of this study indicate that product description can positively and significantly affect enduring and situational involvement. However, the mediation between the product description and purchase intention is only fully found on the situational involvement variable, while enduring involvement does not affect purchase intention. It is different from the results of previous studies, which stated that enduring and situational involvement influence purchase intention. The implications for further researchers, it is recommended to reuse enduring involvement and purchase intention variables and other variables that can lead to enduring involvement concerning consumer purchase intention. Different types of products, populations, and analytical models, can be used to conduct further research to provide a more complete and appropriate description and data.
THE EFFECT OF CHARACTERISTICS OF MANAGEMENT ACCOUNTING SYSTEM INFORMATION (BROADSCOPE, TIMELINESS, AGGREGATION, AND INTEGRATION) AND DECENTRALIZATION OF MANAGERIAL PERFORMANCE
Authors:   Akuntansi, Fakultas Ekonomi dan Bisnis Universitas Ma Chung, Indonesia, Sari Intan Purnama , Noviana Melody ,   Chongqing University, International Bussiness Management, China
Published: December 2022

This study tested the hypothesis developed by Chenhall and Morris (1986) and aims to examine the effect of management information system characteristics of management accounting and decentralization on managerial performance. This study uses contingency theory as a grand theory because the theory of the contingency approach is based on the premise that no management accounting system is always appropriate for all types of companies. This study was analyzed using multiple linear regression analysis. This study used a survey method using a questionnaire with 41 respondents consisting of 5 area managers and 36 supervisors at one pharmaceutical company in Bali province. The results showed that the characteristics of management accounting system information in broadscope, timeliness, aggregation, and integration did not affect managerial performance. It is because managers and supervisors do not fully use the information of the existing management accounting system, so the information management accounting system does not contribute to decision-making that will impact managerial performance. The results of this study are not in line with previous research, but this research supports the contingency theory approach. The decentralization variable has a significant effect on managerial performance. These results support previous research showing that delegating authority from officials to lower-level officials can assist management in making decisions better to improve managerial performance.

Published: December 2022

The urgency of this study is to solve the problem regarding the slow penetration of TikTok Livestreaming shopping; even though the traffic opportunities on TikTok are huge and far outperform any social media application, even if it is compared to applications that existed before TikTok, such as Facebook and Instagram. This study analyzes the factors influencing purchase intention among TikTok users in Indonesia. The number of samples in this study is 180 respondents. A questionnaire with a 5-point Likert scale was used to collect data. The data were processed by using Structural Equation Model (SEM) approach. Of the five direct hypotheses tested, all of them had a significant effect. Thus, we can say Live streaming Shopping Attribute, Products’ Trust, and Sellers’ Trust are the determinant variables of purchase intention. Even though this research has provided factual information on the contribution of antecedent purchase intention variables, it is necessary to expand the variables considered to support the increase in purchase intention, such as the Guarantee Return Policy and seller pacing. Unlike previous studies that mostly assessed the direct effect of exogen variables on purchase intention used a one-level mediating variable, throughout the author’s knowledge, there has been no one to examine the influence of antecedent factors live streaming purchase intention through sequence mediation. This study implies that sellers who use the live streaming channel on TikTok to market their products have to pay serious attention to the quality of the products and guarantee that the products will provide maximum benefits for their buyers.

Published: December 2022

This study explores consumer Panic Buying (PB) and Compulsive Buying (CB) due to consumer anxiety during the COVID-19 pandemic. The role of the religious moderator was also tested to influence consumer attitudes and behavior towards PB and CB to carry out responsible consumption. To empirically test consumer shopping behavior to- wards groceries during the COVID-19 pandemic in East Java, Indonesia. Using the conve- nience sampling approach, data were gathered from young and adult customers in East Java, Indonesia. Through an online survey, 334 customer answers were obtained. The hypotheses were tested using SEM-PLS, which could analyze variables’ effect and role in the complex model. The results indicate that anxiety significantly affects panic buying and compulsive buying. Then panic buying has a significant effect on compulsive buying. Further, the results show that anxiety indirectly influences panic buying and compulsive buying. Likewise, religiosity can suppress consumer anxiety when they want to make panic buying and also compulsive buying. This study further contributes as a pilot study on the role of religion in consumer behavior research in a pandemic context, where consumer religiosity can significantly suppress their anxiety in terms of their panic buying and compulsive buying. This study has special implications for retail stores and government agencies for planning retail and social policies that are positive for consumer behavior during a pandemic.

Authors: Anugrah Rinasa Agistya
Published: December 2022

This study aimed to determine the working principle, troubleshooting, and the effect of CVT roller weight variations on Suzuki Nex-FI 2014 motorcycles. This research process was carried out by analyzing the measurement results of each CVT component and comparing the results. The research method used is an experimental method by holding the throttle at 3,250 rpm; after it is stable, the throttle is rotated up to 10,000 rpm. The results of troubleshooting analysis and measurement of drive belt wear and tear are from the standard size of 19.50 mm to 18.00 mm, and the tolerance limit for use is 18.60 mm. As for the roller variation test results, using a lighter weight roller, for example, 8 grams and 9 grams, get maximum results at low and medium rotational speeds, compared to using an 11-gram roller (standard). The downside of this 8-gram and 9-gram roller is that it only gets good acceleration and torque at low rotational speeds. While at a high rotational speed less than the maximum. If we use an 11-gram roller, the acceleration and torque will get less than the maximum results but maximum power.

The possibility of fixing velocities of fluid motion in model porous medium (glass beads) by measuring the transverse relaxation time T2 by spin echo method is shown. The magnetic field gradient arising due to the difference in the magnetic permeability of the fluid and the porous medium causes a decrease in the average time T2, with makes it possible to fix the fluid motion in the absence of an external magnetic field gradient. The addition of magnetic nanoparticles to the fluid under study increases the dependence of T2 on fluid velocity and increases the sensitivity in determining the permeability of porous medium by NMR-relaxometry.

The analysis of flows with free boundaries is a non-linear problem, since
their forms are not known in advance and must be found. The described
method is effective for various problems with various dynamic
conditions on free boundaries. This iterative method is based on the
quasi-linearization of the boundary conditions for the velocity potential
proposed by A. N. Ivanov in 1962. The iterations include the successive
solutions of the Fredholm integral equations of the second kind
(allowing to determine the pressure over a known boundary) and
singular integral equations (to correct the boundary shape). Here both
the general formulation of the method and its development for specific
types of flows are presented, as well as numerous examples of
solutions for them.

A technique has been developed and, for the first time, sufficiently complete data on the radiation-induced conductivity (RIC) of polystyrene (PS) at a temperature of 79 K, close to the boiling point of liquid nitrogen (77 K). RIC has been studied under pulsed and continuous exposure to electrons with an energy of 50 keV. It is shown that the RIC of PS at a temperature of 79K, as well as at room temperature, determined by the sum of two components: prompt and delayed. Both components at 79K are much smaller than at 298K. The total signal falls off by a factor of 40, while the delayed component falls off by a factor of almost 200, and the prompt component dominant in the RIC signal. The possibility of the occurrence of electrostatic discharges (ESD) in PS with decreasing temperature was studied. It has been shown that PS, which is capable of resisting the occurrence of ESD at room temperature, at 79K passes into the category of materials in which ESD is possible.

Анализ и интерпретация полученных данных с учетом возможных схем поверхностных реакций показал, что после отжига при толщине 1 ML состав слоев (сверху вниз) пленки Fe соответствовал 2 ML Si/Fe. А с увеличением толщины до 2 ML он изменился на Fe/Si/Fe и до 3 ML на Fe-FeSi. Затем после отжига пленки толщиной 3 ML он изменился на FeSi. При 4 ML произошло формирование двухслойной пленки FeSi/FeSi2. И далее при 7 ML и 10 ML состав слоев пленки изменился на Fe3Si/FeSi2 и соответственно Fe/Fe3Si/FeSi2. При этом верхний слой Fe3Si при 7 ML покрылся 0.6 ML сегрегированного Si. А верхний слой Fe при 10 ML после осаждения и отжига при 250oС покрылся 0.3 ML и соответственно 0.6 ML сегрегированного Si. В последней пленке Fe, латеральный размер зерен и средняя высота рельефа пленки составили 10-20 nm и соответственно ~0.4 nm.

This study aims to analyze the stunting prevention program in North Bengkulu Regency through the AGIL concept proposed by Talcot Parsons in the theory of Structural Functionalism. This study uses a qualitative research approach, with case studies. The type of research used is a more in-depth descriptive. Research data were collected through observation techniques, unstructured interviews and document collection. Research informants were determined through purposive sampling technique. The results showed that there were 4 stunting prevention programs in North Bengkulu Regency, namely maternal and child health service programs, nutrition counseling programs and supplementary feeding, social protection programs and sanitation and clean water programs through the use of village funds. These four programs were able to reduce stunting rates in the research locations. Implementation of the program is emphasized on the process of community empowerment. The main targets are changes in personal health behavior and environmental health behavior. The process of adaptation, goal setting, integration, and pattern maintenance are also fairly well systemized in the program realization process. In the future, program implementation needs to be accompanied by the economic maturity of the community.

The problem of terrorism in Indonesia is clearly troubling all circles to any social aspect. Efforts made by the government are still predominantly spontaneous and repressive. Besides, the explanation of social theory in explaining terror behavior in Indonesia is still not able to provide a broad and in-depth insight, so this problem has solved on the phenomena that appear on the surface only. Therefore, it is important to find a complex theoretical explanation that can be overcome to the root. The focus of the study is to analyze how the social reproduction of terror behavior in Indonesia with the perspective of Pierre Bourdieu. The descriptive method with a qualitative approach was used in this research. The method of data collection is done by using observation, interview and documentation techniques. The results of this study show that terror behavior in Indonesia is an inner thought that lasts for quite a long time. The practice of terror does not happen instantly due to a certain momentum reaction. The reproduction of the terror behavior practice indicates the existence of a well-maintained habitus in the community. Their struggle is also inseparable from the existence of social capital and economic capital for the actors. Religious tendencies are used as a media that is considered appropriate to perpetuate the socialization process.

Objectives: Anorexia is one among the most prevalent conditions triggering malnutrition, drastic weight loss and serious health issues in people especially older adults. Habb-e-Hilteet is commonly prescribed Unani pharmacopoeial formulation for anorexia. However, no scientific data is available as to its safety and efficacy. The current study assessed the appetite-inducing effect and safety of Habb-e-Hilteet in Ḍu‘f al-Ishtihā (anorexia) patients.

Methods: An open prospective clinical trial was carried out in 95 clinically diagnosed anorexia patients of either gender (19-65 yrs old). The study was approved by Institutional ethic committee and conducted in accordance with the GCP guidelines. Habb-e-Hilteet, 1 pill (500mg) was administered orally in patients twice daily for 14 days. The safety of the formulation was assessed by important pathological and biochemical indices and monitoring adverse events. The efficacy was assessed on the basis of improvement in the Simplified Nutritional Appetite Questionnaire (SNAQ) score.

Results: Out of 95 patients recruited, 78 completed the trial and 17 patients lost to follow-up. The mean age of patients was 29.8 yrs, with the majority (59.0%) being female. Overall therapeutic response was found to be 96%. A significant (P<0.05) increase in the mean SNAQ score was observed after 7 and 14 days of treatment when compared to baseline. No significant difference before and after treatment was observed in pathological and biochemical indices. No adverse events were reported during the entire study period.

Conclusion: The study results indicate that Habb-e-Hilteet could be a viable treatment option for anorexia with no safety concerns.

Published: December 2022

With the growing teacher attrition rates caused by aging, burnout, and changes in the education system, more and more teaching positions remain vacant every year. Despite the difficulties, however, there are a lot of teachers who choose to remain in the profession; they feel emotionally fulfilled at their jobs and masterfully balance their work requirements and personal life. Resilience might be one of the factors that supports teachers in dealing with the demands of their professional life. The aim of the research is to explore how teacher resilience can help teachers remain in the profession. Transcendental phenomenological research was carried out to reach the aim of the study. A questionnaire for in-service teachers was used to measure their resilience with the Resilience Scale for Adults (RSA) and select interview candidates. Narrative interviews were carried out with eight resilient teachers in three different stages of their careers – working as teachers for five years or less, six to fifteen years and more than fifteen years. The interviewees represented three different cities, various school sizes, and both private and public schools. In the interviews, the teachers’ understanding of resilience and their experiences as resilient educators were explored. Based on the narrative interviews, ways to maintain teacher resilience were proposed. It can be concluded that resilient teachers are more likely to remain in the profession, as they are able to mobilize their internal and external resources to cope with the challenges of the job.
