Authors: Nada Qothrun , Herdiana Ike , Andriani Fitri
Published: November 2022

Individual psychological health can be seen from the health of the skin. Some skin diseases such as psoriasis and atopic dermatitis can be exacerbated by psychological problems. Based on this, a collaboration between specialist doctors and psychologists is needed to screen for psychological disorders in sufferers. One psychological screening instrument is the Depression Anxiety Stress Scale (DASS)-21; this study aims to test its validity and reliability. Non-probability convenience sampling was employed, and 292 participants aged 18-54 were willing to take part in the study. An internal structure validity test was conducted using confirmatory factor analysis, while concurrent validity was assessed by correlating DASS-21 with PHQ-9, GAD-7 and PSS scores. The reliability test was analyzed using composite reliability. The results of the CFA analysis showed that the data matched Lovibond's theory and that all DASS-21 items were valid (RMSEA =.076, CFI=.961, TLI = .955, SRMR = .065). The results of the concurrent analysis showed that the three scales had a positive correlation with the dimensions of DASS-21, while the reliability results showed a satisfactory value (.850 – .923). The results of the study indicate that DASS-21 is a valid and reliable instrument and can be used to measure depression, anxiety and stress in individuals with psoriasis and atopic dermatitis.

Published: November 2022

Children with Autism Spectrum Disorder (ASD) face obstacles in their cognitive development. This study aims to determine the effectiveness of the drum rhythm therapy model in stimulating cognitive abilities (attention, concentration, and short-term memory) in children with ASD. The experiment method was used with a one-group pretest-posttest design. Attention and concentration levels were measured both before and after therapy through a series of observations. A total of 14 children with ASD aged 4–12 participated in the study. All the participants were new students at Gilang Ramadhan Studio Band (GRSB), Surakarta, Indonesia. The drum rhythm therapy was employed with the participants for three months. Data analysis was conducted using Wilcoxon test analysis in SPSS Version 23. Results: The 14 participants showed an increase in attention, concentration and short-term memory scores following the therapy (Z = -2.533b, p = .011, p .05). The results of the study could support the use of the alternative therapy with ASD children to increase their attention, concentration and short-term memory.

Authors: Selian Sri Nurhayati , Khalefa Eslam Younis , Hanifah Lena
Published: November 2022

Women and children in many countries are forced to migrate due to prolonged civil wars and conflicts. The factors and conditions that affect the well-being of immigrant and refugee populations residing in host countries are not widely known. This study aims to identify and explore the personal experiences and migration processes that affect the well-being of immigrant women in Indonesia. A qualitative method and case study design were implemented. Eight refugee women from three different countries were interviewed: Somalia, Palestine, and Afghanistan. It was found that the contexts of identification, personal experiences, the migration process, and the motives or triggers for migration were important factors in influencing the women’s present and future well-being. The study provides implications for the theory of the model used. The application of the theory assisted the researchers to construct a conceptual framework of the subjective well-being of immigrant women.

Authors: Arikhah Arikhah , Sessiani Lucky Ade , Makmun Muhammad , Safitri Ririh Megah , Zuhri Mishbah Khoiruddin
Published: November 2022

Amidst the social-cultural predominance of male ulama in the religious context, female ulama play important roles and yet are often trapped in life-role complexity and gender bias, as they have a responsibility in both the domestic and public domains. This study aims to explore the meaning of the experience of gratitude among female ulama based on the perspective of positive psychology, with reference to the PERMA (Positive emotion, Engagement, Relationship, Meaning, and Accomplishment) model, with further interpretation of gratitude (shukr) from Sufi psychology. Using a qualitative (phenomenological) approach, we held online in-depth interviews with five female ulama participants from across Indonesia and Germany. The research demonstrates the interconnection between themes related to gratitude according to PERMA-Model and the embodiment of gratitude (shukr) in Sufi psychology. These findings provide evidence to support the practical implication of the integrative intervention of positive and Sufi psychology for clinical purposes or to promote flourishing and well-being among women.
Large Lower Lip Defect Reconstruction Using a Karapandzic Flap: A Case Report and Literature Review
Authors: Kim Ji Hoon , Chung Chang Eun , Lee Chong Kun
Published: November 2022

Squamous cell carcinoma is the most common cancer occurring in the oral cavity and oncologic wide cancer excision is a major cause of large lip defects. Large lower lip defect reconstruction with good functional and aesthetic results has always presented a challenge for plastic surgeons. There are various lower lip reconstruction methods depending on its size, location, and surgeon’s expertise. This is a case of a large defect spanning more than two-thirds of the lower lip after wide excision due to squamous cell carcinoma. The Karapandzic flap was used to reconstruct the defect with a commissuroplasty carried out in a second operation, which yielded a relatively good functional and aesthetic result. No recurrences or metastases were observed within a one year follow-up period.

Authors: Camargo Carlos Henrique Ferreira , Blood Marcelo Rezende Young , Medyk Camila , Ferreira Matheus Gomes , Ferro Marcelo Machado , Teive Hélio Afonso Ghizoni
Published: November 2022

Background:

Pain is a frequent non-motor symptom in patients with Parkinson’s disease (PD) and appears to be related to low levels of dopamine. This study describes the characteristics of chronic pain in a group of PD patients undergoing levodopa therapy.

Methods:

This was a cross-sectional study. The pain was assessed in 21 selected PD patients with chronic pain using several scales and instruments. Changes in pain response from levodopa use (wearing-off phenomenon) were monitored.

Results:

The most prevalent type of pain was nociceptive (71.4%), musculoskeletal and dystonic, but neuropathic pain accounted for the highest pain score according to the Parkinson’s Disease Pain Classification System (45.5±30.08). Patients with neuropathic, nociplastic, or nociceptive pain upon wearing-off were those who responded to levodopa (p=0.999). According to the McGill questionnaire, patients with pain upon wearing-off had higher scores in the affective/motivational dimension (p=0.022).

Conclusion:

Using a new pain classification and scoring tool, this study corroborates a good response to levodopa in PD-related pain.

Authors: Menassa Jeanine , Bou Nassar Dima , El Naboulsi Farah , El Naggar Essam , Sunna Nancy , Ghoubar Marcelle
Published: November 2022

Background:

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are associated with substantial disease burdens, including impaired quality of life, functional disability, and lost productivity. Early diagnosis and effective treatment are essential to reducing disease burden and improving long-term outcomes but remain difficult to achieve.

Methods:

To better understand the deficiencies contributing to diagnostic and therapeutic delays in RA and AS in Lebanon, a computer-assisted survey of 1,200 Lebanese citizens was conducted about their awareness and knowledge of these diseases, including characteristics and management.

Results:

Approximately two-thirds and one-third of the survey participants had heard of RA and AS, respectively; two-thirds admitted they knew little about either disease after interviewers provided detailed descriptions. Most participants were aware of the major signs and symptoms of the disease, but most were unaware of serious related comorbidities and complications. While 63% identified rheumatologists as healthcare providers specializing in RA treatment, 89% indicated orthopedists were treating physicians for AS. More than three-quarters of participants understood that early treatment can be effective in RA and AS in preventing disease progression and joint damage, but two-thirds mistakenly considered treatment to be a cure. Among participants who had RA vs AS (57 [4.8%] vs 28 [2.3%]), 21.1% vs 7.1% visited a rheumatologist when initially experiencing symptoms; 64.9% vs 35.7% visited a rheumatologist for follow-up care after diagnosis.

Conclusion:

To close gaps in knowledge and management of RA and AS, initiatives are needed to raise public awareness and educate patients and healthcare providers about the importance of early diagnosis and effective treatment.
Data Fusion of Non-destructive Testing Methods for Bridge Deck Condition Assessment
Authors: Cafiso Salvatore , Di Graziano Alessandro , Goulias Dimitrios G. , Pappalardo Giuseppina
Published: November 2022

Background:

Highway agencies explore the use of non-destructive testing (NDT) for assessing the condition of their infrastructure in the most cost-effective manner. NDTs can provide as-built construction quality, as well as in service condition assessment especially for older structures where some critical information and/or maintenance records are often not available. In many cases, the use of NDTs requires “ground true” data for either calibration or validation. Surveys for obtaining such information is often challenging for in service structures, time consuming and costly.

Aim:

Objective of this paper is to present a data fusion approach for forensic investigation of bridge decks, in which Ground Penetrating Radar (GPR) is used to assess the current condition combined with a Laser Scanner system to verify the bridge design features.

Methods:

The data fusion approach proposed in this study considers using GPR based condition data combined with geometric measurements of the bridge deck obtained from the Laser Scanner system. Such novel fusion approach permits to more accurately measure the current bridge deck conditions in terms of thickness of the bridge deck and rebar depth to assess deterioration. Furthermore, detection of variations in the rebar depth suggested the implementation of a correction procedure for the reflection amplitude of the GPR signal based on true rebar depths instead of the two-way travel time, which is commonly applied.

Results:

This innovative analysis approach provided a more refined assessment of delaminated areas in the bridge deck. The data fusion and suggested analysis methodology was tested on a pre-stressed concrete bridge in Italy.

Discussion:

The approach proposed in this study can be used elsewhere for assessing the condition of bridge decks.

Conclusion:

The merging of such methods is particularly valuable for bridges were construction drawing and records may not be available, and/or there is potential concern of a deviation between design and as-built characteristics (i.e., where quality assurance and quality control records may be questionable).
Toxicity of Algal Foods With Respect to Human Health
Authors: Paz Soraya , Rubio Carmen , Gutiérrez Ángel J. , González-Weller Dailos , Hardisson Arturo
Published: November 2022

Since ancient times, algae have been a staple in the diet of Asian countries.
Currently, due to migratory currents, globalization and new eating habits, algae are
increasingly common in the markets and shops of Western countries. Edible algae can
accumulate elements that, in high quantities, pose a toxic risk to consumers. Various
authors have recorded high concentrations of toxic metals and trace elements in edible
algae. However, in all cases, it has been shown that some species of algae, such as the
Hizikia fusiform alga, tend to accumulate high concentrations of inorganic arsenic,
making it necessary to modulate its consumption. Likewise, algae of some
geographical origins are more exposed to contamination; therefore, it is recommended
to avoid their consumption. Likewise, in cases of people with a susceptibility to
suffering from thyroid problems, it is recommended to consume smaller amounts of
algae, avoiding some species, such as some species of red algae, which can accumulate
higher concentrations of iodine. In conclusion, it is recommended that the consumer
varies between species, avoiding consuming a single species of algae, as well as
avoiding those algae that come from places with a higher degree of contamination, as it
has been shown that they are accumulators of toxic elements. Likewise, it is necessary
to monitor the levels of certain toxic elements in edible algae in order to ensure the
quality of these foods.

Authors: Sianturi Duma Aulia , Gunawan Atma
Published: November 2022

Background: Continuous Ambulatory Peritoneal Dialysis (CAPD) is an effective modality of renal replacement therapy in patients with kidney failure. Peritonitis associated with peritoneal dialysis remains a significant challenge and complication to success long-term peritoneal dialysis.
Aim: This study aims to report the peritonitis as a cause of death of CAPD patients for six years in end-stage renal failure (ESRD) patients at RSUD Dr.  Saiful Anwar Malang.
Methods: A descriptive study was conducted involving 40 patients with end-stage renal failure who underwent CAPD therapy with peritonitis as the cause of patient mortality by taking data from the CAPD Center medical record at RSUD Dr.  Saiful Anwar from August 2014 to July 2020.
Results: From 674 end-stage renal failure patients who underwent CAPD, 248 patients (36.8%) died, and 426 patients (63.2%) survived to 5 years. CAPD peritonitis is the second most common cause of 40 (16.1%) mortality cases after cardiovascular disease. The most common bacteria causing CAPD peritonitis was coagulate-negative Staphylococcus, with as many as 15 (37.5%) cases.
Conclusion:  the most common cause of mortality was Staphylococcus coagulase-negative (37.5 %,), a bacteria that come from touch contamination or infection at the exit site. So that patients and caregivers must be trained to carry out proper exit-site, and it is essential to maintain good hand hygiene before performing exit-site. Appropriate prevention and management of peritonitis are critical to patients' long-term success on peritoneal dialysis.
Ventricular tachycardia in Arrhythmogenic Right Ventricular Cardiomyopathy: How to Manage?
Authors: Ivana Diah , Tri Tjahjono Cholid
Published: November 2022

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a condition characterized by fibrofatty replacement of the RV myocardium due to genetic abnormality. Structural changes may be absent or minor in the early stages of the disease and be localized in a specific region of the RV. Clinically it appears as RV electrical instability. To reduce the risk of arrhythmic events or sudden cardiac death, device therapy and pharmacotherapy may be recommended. In this paper, we describe a case of a female with ARVC and a brief discussion based on a literature review. The patient presented with chest discomfort accompanied by palpitation. An electrocardiogram (ECG) showed ventricular tachycardia of RV apex origin, and convert to symmetric inverted T-waves and probable epsilon waves in the right precordial leads, mimicking a pseudo-right bundle branch block (RBBB) pattern following electrical cardioversion. The parasternal short-axis view of echocardiography shows severe right ventricular dilatation. Subsequent workup using CMR was planned but the patient refused. We diagnosed this patient with ventricular tachycardia on a background of suspicious arrhythmogenic right ventricular cardiomyopathy. We were able to provide accurate diagnosis and treatment, avoiding potentially fatal consequences. As a result, it is critical to recognize potential ARVC ECG findings and to know when to pursue further research and implement therapies.

Published: November 2022

BACKGROUND

Hepatocellular cancer (HCC) is associated with high mortality, and early diagnosis leads to better survival. Patients with cirrhosis, especially due to nonalcoholic fatty liver disease and viral hepatitis, are at higher risk of developing HCC and form the main screening group. The current screening methods for HCC (6-monthly screening with serum alpha fetoprotein and ultrasound liver) have low sensitivity; hence, there is a need for better screening markers for HCC.

OBJECTIVE

Our study, TENDENCY, aims to validate the novel screening markers (methylated septin 9, urinary volatile organic compounds, and urinary peptides) for HCC diagnosis and study these noninvasive biomarkers in liver disease.

METHODS

This is a multicenter, nested case-control study, which involves comparing the plasma levels of methylated septin 9 between confirmed HCC cases and patients with cirrhosis (control group). It also includes the comparison of urine samples for the detection of HCC-specific volatile organic compounds and peptides. Based on the findings of a pilot study carried out at University Hospital Coventry & Warwickshire, we estimated our sample size to be 308 (n=88, 29% patients with HCC; n=220, 71% patients with cirrhosis). Urine and plasma samples will be collected from all participants and will be frozen at –80 °C until the end of recruitment. Gas chromatography–mass spectrometry will be used for urinary volatile organic compounds detection, and capillary electrophoresis–mass spectrometry will be used for urinary peptide identification. Real-time polymerase chain reaction will be used for the qualitative detection of plasma methylated septin 9. The study will be monitored by the Research and Development department at University Hospital Coventry & Warwickshire.

RESULTS

The recruitment stage was completed in March 2023. The TENDENCY study is currently in the analysis stage, which is expected to finish by November 2023.

CONCLUSIONS

There is lack of effective screening tests for hepatocellular cancer despite higher mortality rates. The application of more sensitive plasma and urinary biomarkers for hepatocellular cancer screening in clinical practice will allow us to detect the disease at earlier stages and hence, overall, improve HCC outcomes.

Abstract: Every day, many people around the world lose their lives in road accidents. Most deaths occur due to lack of access to adequate medical care. Over 1.25 million people die in road accidents. The goal of this project is to find out where the vehicle is located and locate the vehicle by sending messages through a system located within the vehicle system. In most cases, you may not be able to locate the scene of the accident. I don't know where the accident happened. To avoid such situations, we project an accident detection warning system for emergency assistance using IOT and mobile applications. As soon as an accident is detected, our system will identify the appropriate coordinates and send them to nearby emergency services and the victim's family so that they can arrive as soon as possible.

GST Implication and its Impact-A Public Perspective
Authors: S Dinesha A
Published: November 2022

Abstract: Goods and Services Tax issue has been debated for several years since 2005 some of the individuals support the implementation of GST, some oppose to it. The main reasons for the consumer unwilling to support or opposed the implementation of GST because of the fear of price hike majority of the respondents believed that GST would causes higher inflation. In addition , lack of information and unclear about the purpose of GST implementation consumers are too worried until they brought up one issue , particularly regarding charges of 6% of GST on money withdrawn from the ATM . This will replace sales tax and service tax which has been payable tax annually, where as GST is payable monthly. Because of this SME’S should plan for additional cash and be aware that GST is payable whether they have received payment from their customers or not. This paper begins with introduction to GST, Concept of GST, further analysis of challenges, problems of indirect tax system and GST implicationin Indian economy. It also cites on effective management of GST implications in Indian Economy. Hence, this present article explores how perception of public on GST implication and its impact on the Indian economy. The study has been conducted with respect to Shivamogga region general public professionals and non-professionals. The primary data have collected from 100 respondents and draws some conclusions about possible future directions for research in GST offered by various researchers.

Published: November 2022

Abstract: The underwater images are a good source of information which explores idea about sea creatures, to study about seafloor hydrother-mal vents. Low contrast, color distortion and poor visual appearance are the major issues that an underwater image has to undergo. Such problems were caused by dispersion and refraction of light as they penetrate from rarer to denser media. The scattering of light reduces color contrast. The influence of water in underwater images is not only due to scattering but also due to the presence of underwater organisms. Here we introduce an improved method for underwater image enhancement based on the fusion method that is capable to restore accurately underwater images. The proposed work takes a single image as the input and a sequence of operations such as white balancing, gamma correction and sharpening are performed on the input image. Finally wavelet image fusion of the inputs is done to obtain the resultant output. In the initial stage, color distorted input image is white balanced to remove the color casts maintaining a realistic subsea image. In the second stage, CLAHE is performed on the gamma corrected image. CLAHE plays a significant role in luminance enhancement of underwater images. At the same time, histogram equalization is performed on the sharpened image and finally performed the wavelet fusion.

Critical thinking and problem-solving skills are necessary skills in the 21st century learning. However, the initial tests of students' critical thinking and problem-solving skills showed low scores. Therefore, the purpose of this study was to improve students’ critical thinking and problem-solving skills through the POGIL (Process Oriented Guided Inquiry Learning) model combined with a digital mind map based on online learning.  This study uses the Classroom Action Research (CAR) method following the design of Kemmis & McTaggart, which consists of 4 stages, namely planning, implementing the action, observing, and reflecting. The stages of the POGIL model consist of orientation, exploration, concept formation combined with making digital mind maps, applications, and closings. The research subjects were students of class XI MIPA 4 of SMAN 2 Malang, totalling 28 students which consisted of twenty girls and eight boys. The percentage of critical thinking skills achievement increased by 29.61% from 66.87% in the first cycle to 86.67% in the second cycle. Problem-solving skills increased by 22.16% from 70.27% in the first cycle to 85.84% in the second cycle. The results showed that the POGIL model combined with a digital mind map based on online learning could improve students’ critical thinking and problem-solving skills.
To the calculation of the stability of lattice elements of steel structures
Authors: Belyi Grigory I.
Published: November 2022

Introduction. The practical method of calculating lattice elements of steel structures for local and general stability contains an internal contradiction. The general stability check assumes the presence of an additional branch bending arrow in the lattice plane, and the local stability check negates it, which does not guarantee local stability when checking the general stability of the lattice rod. The calculated combinations of forces at the ends of any structural element, under the action of the same calculated combinations of loads, almost always have different values. Consequently, the longitudinal forces in the branches of the lattice elements, separated by the calculated length from the lattice plane, will always be variable, which is not taken into account in the current design standards.

Materials and methods. To eliminate the mentioned contradiction, an analytical method is proposed for solving the problem of general stability of lattice elements of steel structures, taking into account the provision of local stability of the most loaded branch. The solution of the problem of stability of a branch from the lattice plane (two-branched elements) is carried out using the inverse numerical-analytical method: according to a given stress-strain state in the most loaded section of the elastic branch, acting and fictitious, compensating for the development of plastic deformations, deformation forces are numerically determined. Then, by the inverse analytical solution of the deformation problem, the actual loading of the branch at its ends is established.

Results. The coefficient of overall stability of lattice elements is determined by solving a quadratic equation that includes an additional dependence on the coefficient of stability of the branch in the lattice plane. The stability coefficient of the branch from the lattice plane is obtained in the general case of loading by a longitudinal force with different values of end eccentricities in combination with a uniformly distributed axial load.

Conclusions. An analytical solution to the problem of general stability of lattice elements is proposed, taking into account the stability of the branch. The solution of the problem of stability of a branch from the lattice plane (two-branched elements) is obtained when it is actually loaded with a variable longitudinal force acting with different values of terminal eccentricities.

Published: November 2022

Conditional expectations and residuals (CERES) and partial residual (PR) plots have been used in linear regression model for the identification of outliers. But not much work has been done on how they perform in generalized linear models (GLM). Binomial regression model is a very important type of GLM which have wide applications in dealing with Liver cancer and many other types of data. In this paper, CERES and PR plots is used in binomial regression to detect the outliers. Through real data set, the performance of these plots on the detection of possible outliers is observed separately. The CERES plot performs well in order to diagnose this problem. However, the performance of the CERES and PR plot is found very similar to detect outlier by using simulated data but visualization of CERES plot is better as compared to the PR plots.
