Attractor landscapes: A unifying conceptual model for understanding behaviour change across scales of observation
Authors: Heino Matti Toivo Juhani , Proverbio Daniele , Resnicow Ken , Marchand Gwen , Hankonen Nelli
Published: July 2022

Models and theories in behaviour change science are not in short supply, but they almost exclusively pertain to a particular facet of behaviour, such as automaticity or reasoned action, or to a single scale of observation such as individuals or communities. We present a highly generalisable conceptual model which is widely used in complex systems research from biology to physics, in an accessible form to behavioural scientists. The proposed model of attractor landscapes can be used to understand human behaviour change on different levels, from individuals to dyads, groups and societies. We use the model as a tool to present neglected ideas in contemporary behaviour change science, such as hysteresis and nonlinearity. The model of attractor landscapes can deepen understanding of well-known features of behaviour change (research), including short-livedness of intervention effects, problematicity of focusing on behavioural initiation while neglecting behavioural maintenance, continuum and stage models of behaviour change understood within a single accommodating framework, and the concept of resilience. We also demonstrate potential methods of analysis and outline avenues for future research.

Published: July 2022

Background. While there is ample theoretical and empirical interest in overparenting, little is known about how overparenting of adolescents operates in everyday family life. This study describes the development and validation of a novel instrument to assess overparenting with Experience Sampling Methods – The Momentary Overparenting (MOP) scale.Methods. Following 143 (Belgian and Dutch) adolescents for 7 subsequent days, we measured overparenting (i.e., worry, interference, and unnecessary help), autonomy support and psychological control 5 to 6 times per day. Using multilevel structural equation modeling on 1865 parent-adolescent interactions, we investigated the scale’s psychometric properties: within-family and between-family reliability, convergent and divergent validity.Results. Overparenting was characterized by both stable differences between families (46%), as well as dynamic fluctuations within families over time (54% of the variance). The MOP could reliably assess such real-time dynamics in overparenting. Momentary assessments correlated meaningfully with established instruments for overparenting at the between-family level. Within families, adolescents experienced interactions with more overparenting as more psychologically controlling and less autonomy supportive. Between families, overparenting correlated negatively with mothers’ autonomy support and positively with mothers’ psychological control. Conclusion. Worry, interference, and unnecessary help may be important expressions of overparenting in everyday family life – which can now be reliably measured from moment-to-moment as a distinct parenting construct.

Some forms of uncertainty may suppress the evolution of social learning
Authors: Turner Matthew Adam , Moya Cristina , Smaldino Paul E. , Jones James Holland
Published: July 2022

Social learning is essential to survival. It is likely to evolve when it is more efficient than asocial, trial-and- error learning. The consensus in cultural evolutionary theory holds that some amount of environmental variability and uncertainty about the best decisions are necessary for social learning to evolve. However, current models for the evolution of social learning tend to conflate forms of uncertainty, and rarely consider different ones in tandem. Moreover, many models are limited by considering only two possible behaviors and environ- mental states. Here we use evolutionary agent-based modeling to identify the complex ways in which differ- ent forms of uncertainty affect social learning. We model a time-varying environment with dozens of possible behaviors performed by agents engaging in individual and social learning. We show that ambiguous payoffs, larger possible decision sets, and shorter agent lifespans some- times increase social learning prevalence, as expected. However we also find which concrete uncertainty conditions cause evolution to select against social learning.

Published: July 2022

Background: Patients of end stage renal diseases on hemodialysis often suffer from multiple comorbidities leading to poly pharmacy which might lead to potential drug-drug interaction.
Aims and Objectives: The aim of this study was to assess the pattern of medicines prescribed to patients undergoing dialysis in a tertiary care hospital.
Materials and Methods: A cross-sectional observational study was conducted on patients admitted in dialysis unit to assess the pattern of drug use among them in a tertiary care hospital in eastern India from June to December 2019. With prior approval from the Institutional Ethics Committee the demographic details, biochemical and hematological parameters and details of medicine use were captured in a pre-designed, pre-validated form. The data were interpreted in mean, percentage, and diagrams using Microsoft Excel 2010.
Results: Among the recruited patients (n=160), majority of them were homemakers (30.62%) and unemployed (30%), out of which 42.75% were male and 51.25% were female suffering from chronic kidney diseases (70.62%) and acute kidney injury (29.37%). The mean age of the study population was 46.7±16.35 years. The mean pre-dialyzed systolic and diastolic pressure (mm Hg) and pulse rate recorded was 140.56±21.94, 83.04± 13.29, and 81.97±5.51, respectively. Before hemodialysis, the mean hemoglobin level was 11.135±1.219 gm/dl, urea139.81±69.29 mg/dl, creatinine 6.48±3.77mg/dl, sodium 136.63±4.07mEq/L, and potassium 4.47± 1.00 mEq/L. Major comorbidities found associated with these patients were hypertension (68.75%), diabetes mellitus (52.5%), and hypothyroidism (11.87%). The commonly prescribed drugs were anti-hypertensive (73.8%), proton pump inhibitors mainly pantoprazole (68.1%), diuretic (86.2%), calcium supplements (74.3%), insulin (53.1%), and erythropoietin (49.3%). Average number of drugs administered per patient was 5.3±1.78.
Conclusion: Patients in the dialysis unit are exposed to multiple drugs at a time due to their association with multiple comorbidities. Physician need to deal such patients very cautiously to avoid drug-drug interactions and adverse drug effects.

Authors: Bala Murali Krishna Patibandla  , Mriganka Deuri Bharali  , Ershad Hussain Galeti  , Saqib Shahab
Published: July 2022

Background: Kidneys are a pair of retroperitoneal organs supplied by a single renal artery and vein. However, the classic illustration of the renal vasculature, formed by one renal artery and one renal vein, occurs in ≤25% of cases. MDCT angiography is presently the most preferred investigation for assessing prospective renal donors.
Aims and Objectives: This study aims to familiarize urologists with the variations found in the renal vascular system, emphasizing prevalence, the adequate, appropriate terms, and the clinical and surgical implications involved.
Materials and Methods: A cross-sectional study in 50 patients clinically indicated to undergo CT Renal angiographic study over 2 years is included in the study. This study was carried out to look for any anatomical variants in renal vasculature. CT examination was performed on a multidetector 16 slice CT Siemens scanner in the department of radiodiagnosis. Once conventional CT is done, the data obtained can produce 3D post-processing images that simulate conventional angiograms.
Results: Out of 50 patients, single renal arteries are present in 27, and multiple renal arteries are present in 23 patients. Out of 27 patients with single renal arteries, 22.2 % has perihilar arterial branching. The most common variant was accessory renal arteries, which are found in 56% of individuals, followed by aberrant renal arteries found in 30% of individuals. Double renal arteries are found in 8.7% and triple renal arteries in 4.3% of cases. Out of 50 patients, 48 patients have a single renal vein, whereas two patients have supernumerary veins. The present study found right renal vein duplication in only 2% of patients.
Conclusion: Renal arteries and veins show numerous variations in their origin sites, numbers, course, and division patterns. These variants exist in the population with high prevalence and are thus crucial in preoperative and intra-operative analysis for better prognosis and reduced complications. Preoperative CT evaluation of renal vasculature using MDCT angiography helps depict the presence or absence of renal arterial and venous variants.
To evaluate the role of double J stent versus no stent in patients of renal and upper ureteric calculus undergoing extracorporeal shock wave lithotripsy
Authors: Shirale Vaishali , Jain Sudhir Kumar , Kaushik Rohit
Published: July 2022

Background: Extracorporeal shock wave lithotripsy (ESWL) was first introduced by Chaussy in 1980 for the treatment of urolithiasis, which has revolutionized the treatment of urinary stones. Renal colic, urinary tract obstruction, uremia, and renal failure can occur because of the stone fragments obstructing the ureter during the post-ESWL period. The role of double-J (DJ) stents in ESWL is controversial.
Aims and Objectives: The aim of the study was to evaluate the role of DJ stent in patients with renal and upper ureteric calculus undergoing extracorporeal shockwave lithotripsy.
Materials and Methods: Two hundred patients with solitary calculus 5 mm–2 cm in size, amenable to ESWL, located in renal pelvis, upper or middle calyx, upper ureter visiting Lok Nayak Hospital, New Delhi from December 2015 to April 2019 were studied and randomized into two groups: Test group (non-stented, 100 patients) and control group (Stented, 100 patients). Both groups underwent ESWL and subsequently compared for the following parameters: Stone clearance, post lithotripsy pain and analgesic dose requirement, number of ESWL sittings and shockwaves required, steinstrasse, urinary tract infection (UTI), and hematuria. Patients were followed up for 3 months after stone clearance to look for any recurrence.
Results: There was a significant difference (P<0.05) in the two groups with smaller number of ESWL sittings and number of shockwaves required, low frequency of colicky pain episodes and mean pain score, less analgesic dose requirement, lower incidence of hematuria, and UTI in non-DJ stent group. The overall stone clearance was higher in the non-DJ stent group (96.4%) as compared to the DJ stent group (89.3%). The incidence of steinstrasse was higher in the DJ stent group (10.7%) as compared to none in the non-DJ stent group.
Conclusions: There is no additional benefit of DJ stent on stone clearance, rather stenting further increases the morbidity due to associated complications. DJ stenting should not be performed in patients undergoing ESWL for renal and upper ureteric calculus up to 2 cm size.
An observational cross-sectional study of the serum sodium levels and their association with severity in chronic liver disease patients in a tertiary care center in Haryana
Authors: Navtej Singh  , Tarun  , Chamoli Ankit
Published: July 2022

Background: Chronic liver diseases (CLDs) cause significant morbidity and mortality worldwide. Reduced serum sodium concentration is a common finding in patients with cirrhosis, being the most common electrolyte disorder in this setting.
Aims and Objectives: The objectives of the study were as follows: (1) To find the association of altered serum sodium levels with the disease severity (as per Child-Pugh Score [CPS] and Model for End-Stage Liver Disease [MELD]) and (2) to assess for the type of dysnatremias commonly found in CLD and its association with complications of CLD.
Materials and Methods: It is an observational cross-sectional study. It was done for 18 months (June 2019 till May 2020) in the Department of General Medicine of Bhagat Phool Singh Government Medical College for Women, Khanpur Kalan, Sonipat, Haryana.
Results: Among all patients with CLD, 30.8% had serum sodium levels ≤130 mEq/L), 32.5% had 131–135 mEq/L, and 36.7% had ≥136 mEq/L. Thus, hyponatremia was observed in 63.3% of the patients. Mean MELD score and mean CPS were significantly higher in patients with reduced serum sodium levels. In addition, Child-Pugh Class C was significantly more common in patients with serums sodium levels ≤130 mEq/L as compared to other patients. Hepatic encephalopathy, hepatorenal syndrome, and coagulopathy were found to occur significantly more common in patients with serums sodium levels ≤130 mEq/L.
Conclusion: Hyponatremia is very common among patients with CLD. Low serum sodium level was associated with more severe liver disease, more complications, and higher mortality.

Authors: Prem Singh  , Sanjay Kumar  , Koushik Biswas  , Abha Jyoti  , Amarendra Tripathi
Published: July 2022

Background: Peripheral artery disease (PAD) is due to abnormal Narrowing of arteries other than heart and brain (primarily due to atherosclerosis). PAD is the most common form of PVD.
Aims and Objectives: In the present study, we analyzed Vitamin D association with peripheral vascular diseases as well as coagulation and inflammation parameters.
Materials and Methods: The study was conducted for 100 PAD patients of 18–70 years age and divided in Group I≤20ng/ml and Group II>20ng/ml for serum Vitamin D level. A single, oral, and high- dose Vitamin D3 supplementation 1,20,000IU was given in GroupI. At baseline and at the end of the study after 1 month, Ankle Brachial Index, modified Rankin Scale, Vitamin D, Inflammation and coagulation parameter, HbA1c, etc., were performed in all patients. Evaluation was done using SPSS. The level P<0.05 was considered as the cut off value of significance.
Results: The majority of the PAD patients were Vitamin D deficient and have higher HbA1c level with statistically significant (P<0.05) association. This is because low Vitamin D is the risk factor for diabetes in which HbA1c level is higher.
Conclusion: Asingle, oral, and high-dose Vitamin D3 supplementation did not alter parameters of inflammation and hemostasis in patients with peripheral arterial disease, adding more data to other studies that did not confirm a causal role of Vitamin D in cardiovascular disease.

Authors: Dasgupta Sibaji , Guria Sourabh
Published: July 2022

Atraumatic subdural hematoma (SDH) is a rare occurrence in neurosurgery practice. Such a case in pregnancy is also very rare. Here, we present a case of 33 weeks pregnant female presented with SDH which was operated and there was recurrence of similar hematoma in the same patient in the postpartum period. The primary cause in both the hematomas was unknown, but a pregnancy related or other risk factors may be responsible for causation of the hematomas in this case.
Study of cardiovascular dysfunction in chronic liver disease in a tertiary care hospital in eastern India
Authors: Sudipta Bandyopadhyay  , Prabir Kumar Kundu
Published: July 2022

Background: Chronic liver disease (CLD) exhibits characteristic hemodynamic changes along with pathological changes in the myocardium. Compensated by the decreased systemic vascular resistance, overt heart failure is usually not seen, and thus cardiac pathology is frequently overlooked.
Aims and Objectives: The objectives of the study were to study the presence, types, and severity of cardiovascular (CV) dysfunction in patients of CLD.
Materials and Methods: An observational cross-sectional study on 50 patients of CLD at Calcutta National Medical College and Hospital, with all relevant investigations.
Results: Out of a sample of 50 patients, of which 14.3% were mild, 34.3% moderate and 51.4% severe CLD (by Child-Pugh Class), 28.6% had a high normal heart rate (90 to 100/min), 45.7% had increased stroke volume index, and 42.9% increased cardiac index, reflecting hyperdynamic circulation. In 42% cases, left ventricular ejection fraction was increased more than 65%, reflecting hyperdynamic circulation, but decreased <55% in 23% cases, which may be an indicator of cirrhotic cardiomyopathy. Ejection fraction is significantly (P=0.016) increased after paracentesis in 33.3% patients, reflecting the mechanical effect of ascites on cardiac function. Diastolic dysfunction was present in 60% (P=0.012) and left ventricular mass index was increased in 45.7% cases. All the parameters correlated with increasing Child-Pugh Class severity of CLD.
Conclusion: A high level of awareness is needed to take into account the presence of CV dysfunction and cirrhotic cardiomyopathy in patients of CLD and predict the risk of adverse cardiac events. Specific treatment modalities need further study to improve prognosis in these patients.
A comparative study of mesh fixation with non-absorbable versus delayed-absorbable monofilament suture in Lichtenstein tension-free hernioplasty in a medical college
Authors: Subhadip Sarkar
Published: July 2022

Background: Mesh placement and subsequent fixation are an important aspect of hernia surgery. Different methods are available in modern days for fixing the mesh in inguinal hernioplasty surgery in both open and laparoscopic approach. However, sutures are still preferred by most of the surgeons because of its easy availability and cost- effectiveness. Conventionally, non-absorbable sutures are used to fix mesh.
Aims and Objectives: The objective of our present study is to compare the post-surgical outcomes of mesh fixation with monofilament non-absorbable sutures versus monofilament delayed absorbablesutures.
Materials and Methods: This prospective and randomized study was conducted at the Department of Surgery, ESIC-PGIMSR, Joka during the period of January 2017 –March 2019. Total 160 patients having unilateral uncomplicated inguinal hernia were included in this study; operated by the same surgical team. The patients were divided into two groups, each of 80 patients. In Group I, mesh fixation was done with delayed absorbable sutures whereas, in Group II, mesh was fixed with non-absorbable sutures. The data were analyzed with appropriate statistical tests such as Chi-square test and P < 0.05 that were considered as statistically significant.
Results: The development of post-operative pain was more common in Group II. The difference was statistically significant at 6 months post-operative time (P =0.042). When we compared the post-operative par esthesia in both surgical groups, more number of patients developed it in Group II but no significant statistical difference was observed (P-value came as 0.784, 0,221, and 0.385 after analyzing 3 months, 6 months, and 1 year data, respectively). Regarding other complications such ash ematoma, wound infection, seroma formation, and scrotal/ cord edema, no statistically significant differences were observed in either group (P-values were 0.339, 0.149, 0.313, and 0.117, respectively). No patient developed chronic discharging sinus post operatively in either group. No recurrence was noted in any patients included in this study, after 1 year of follow- up.
Conclusion: Using delayed-absorbable suture material with air knotting technique for mesh fixation in Lichtenstein tension-free open inguinal hernioplasty causes less chance of post-operative inguinal pain and pare sthesia. Hence, it is a good alternative choice for surgeons; in terms of safety and efficacy.
Outcome predictors in patients (older than 14 years) with acute febrile encephalopathy: Role of cerebrospinal fluid analysis
Authors: Nandmer Vijay Kumar , Nandmer Ajay Kumar
Published: July 2022

Background: Managing patients with acute febrile encephalopathy (AFE), characterized by fever and altered mental status, is one of the primary reasons for hospitalization and mortality. Understating the predictors of AFE outcome will assist the physician in providing early clues and subsequent inventions to tackle the problem.
Aims and objectives: To evaluate the predictors of outcome in patients with AFE, focusing on the cerebrospinal fluid (CSF) analysis.
Materials and Methods: A prospective observational study was performed on 507 patients with fever and altered mentation (above 14 years of age) in the Department of General Medicine between December 2017 and May 2019. CSF analysis was done to obtain protein, glucose, cell count, and adenosine deaminase (ADA). Computed tomography/magnetic resonance imaging and PS for malaria parasites were also performed.
Results: AFE was more common in males (54.63%). Tuberculous meningitis (TM) (44.8% vs. 41.6%) followed by bacterial meningitis (BM) (25.7% vs. 25%) was the most common diagnosis in females and males respectively. Mortality was more common in TM (57.4%) followed by BM (21.3%) patients. Of the 211 patients with TM, those who died had CSF protein ≥90 (49.7%; P= 0.012), CSF glucose ≥35 (53.2%; P=0.002), CSF cells ≥60 (47%; p=0.012) and ADA ≥15 (31.5%; P<0.001). Of the 127 patients with BM, those who died had CSF protein ≥90 (100%; P<0.001), CSF glucose ≥35 (78.3%; P <0.001) and CFS cells ≥60 (100%; P <0.001).
Conclusion: CSF analysis could be important for predicting the outcome and should be done as soon as possible after the clinical judgment of the AFE.

Authors: Sanjuna D  , Nikita Singh  , Gautam Chandrakoshi  , Rashmi Jain  , Ankit Jain
Published: July 2022

Background: The etiological agent for pandemic COVID-19 is severe acute respiratory syndrome corona virus 2. Hematological and biochemical parameters are the indicators of inflammation and coagulopathy.
Aims and Objectives: The present study aimed to determine how effectively the hematological parameters and biochemical markers can help predict the severity of critically ill COVID-19 patients.
Materials and Methods: The current retrospective cohort study was conducted among 200 COVID-19 patients admitted in the Sanjay Gandhi Memorial Hospital, Rewa, Madhya Pradesh, India. In our lab’s computerized system, certain hematological and biochemical parameters of the patients were retrieved and recorded. Receiver operating characteristics (ROC) curve analysis was done to evaluate the diagnostic accuracy of hematological and biochemical parameters.
Results: Total leukocyte count (TLC), absolute lymphocyte count (ALC), neutrophil to lymphocyte ratio (NLR), D-dimer, and serum ferritin had a significant relationship with severity among ICU patients (P<0.05). ALC, D-dimer, and serum ferritin can be used to predict the severity of COVID patients with area under the ROC-AUC curve values of 0.717, 0.725, and 0.710, respectively. Platelet to lymphocyte ratio, lymphocyte to monocyte ratio, and C-reactive protein were not useful to predict the severity of COVID illness.
Conclusion: Hb concentration, TLC, NLR, D-dimer, and serum ferritin were significantly raised in critically ill COVID patients. ROC curve analysis showed that ALC, serum ferritin, and D-dimer were able to predict the severity of COVID illness effectively. Conclusively, these parameters can be used to track the prognosis of patients.

Authors: Pamarthi Srinivas  , Sai Phanindra M  , Sathish Kumar Dake  , Raju Byshetty
Published: July 2022

Background: Phalynx fractures account for 2.9% of fractures and are most commonly associated with machinery injuries in middle and young-aged individuals. Many external fixators are used for the fixation of phalanges with complexity which are costly. In this study, we used a cheap, easy fixator to construct and can be used as an emergency or definitive fixation.
Aims and Objectives: The aim of the study was to evaluate the functional outcome after using a cheaper external fixator for phalynx fractures in place of costly mini external fixators for fixation which is used normally.
Materials and Methods: We had done this study on 28 patients with phalangeal fractures, mostly due to machinery injuries which are open injuries (22 patients), with male predominance (20). The mean age group in our study was 34.89 years. The most common phalynx involved was the middle phalynx of the ring finger (11 cases). We made a fixator with syringe caps and K-wires as fixators.
Results: Total active motion score used to assess the functional outcome after 3 months of follow-up and serial X-rays for assessing union. At the end of 3 months, 22 patients (78.5%) had shown excellent results, two patients (7.1%) had fair results, three (10.7%) had good results, and one patient (3.5%) had poor results.
Conclusion: We suggest this fixator as this is cheap and easy to reconstruct with the instruments commonly available in OT. This fixator gives similar results to complex high-end fixators as compared to previous studies. This needs less expertise and training and is cost-effective for the patient.

Published: July 2022

In recent years, research into the effects of torsion in concrete members and the impact of novel materials on torsional behavior has increased. Slurry Infiltrated Fiber Concrete (SIFCON) is a special kind of Fiber Reinforced Concrete (FRC). The purpose of this research is studying the influence of SIFCON on torsion behavior of reinforced concrete beams. In experimental program, five beam specimens are casted and tested under pure torsion. Two of them from normal concrete as a references, two from SIFCON with steel fiber volume 10% and the last beam was normal concrete strengthening by SIFCON with the steel fiber volume 10%. The results have been indicated enhancement in ultimate torsional moment of SIFCON beams when compared with reference, normal concrete beam. In addition, by reducing the twist angle and increasing torsional stiffness, the resistance moment of torsion was improved.

Authors: Novianarenti Eky , Mustaghfirin Muhammad Anis , Abdillah Achmad Fardiansyah
Published: July 2022

Axial fans are widely applied in the industrial sector. Axial fans are used for ventilation systems and other cooling systems. The blade design of the axial fan requires an airfoil study. Unfortunately, there are not many articles that discuss in detail about airfoils, especially on noise and vibration that can have an impact on axial fan performance using computational fluid methods or software. This study performs axial fan analysis using computational methods with ANSYS Fluent, Static Structural, Modal and Harmonic Response software to obtain the values of stress, vibration and fluid flow. The experimental design used is using NACA 1412, 4142, and 6412 airfoils on the tip with variations in angles of 60, 74, and 80. While on the hub uses NACA 9312, 9412, and 9512 airfoils with angle variations of 20, 30, and 60 and simulated to find the value of vibration and stress analysis. The 3D axial fan design is imported into the ANSYS Fluent, Static Structural, Modal and Harmonic Response software. The simulation results using Ansys Fluent, shows the pressure contour with a maximum value of 198.424 Pa and Velocity streamline with a maximum value of 28.8669 m/s. the results of the Ansys Static Structural simulation show that the average total deformation is 9.9275e-008 m. The simulation results using Ansys Modal, show that there is a natural frequency of 287.8 Hz and the simulation results of Ansys Harmonic Response obtained an average total deformation of 5.0809e-012 m and the equivalent stress value with a maximum value of σ y, max = 0.20186 Pa.

Pelaksanaan Perjanjian Baku dan Akibat Hukumnya bagi Konsumen
Authors: Eleanora Fransiska Novita , Dewi Aliya Sandra
Published: July 2022

Artikel ini bertujuan untuk mengetahui penerapan perjanjian baku dan akibat hukumnya bagi perlindungan konsumen, dikarenakan dalam praktiknya ada perjanjian yang tidak ada kata sepakatnya dan dibuat secara sepihak. Artinya ada pihak-pihak tertentu yang membuat isi perjanjian dan pihak lainnya harus menyepakatinya tanpa persetujuan yang biasanya disebut dengan klausula baku. Hukum perlindungan konsumen di Indonesia tidak mengatur secara eksplisit mengenai penjanjian yang di dalamnya memuat klausula baku, Klausula baku jika diterapkan akan merugikan konsumen sebagai pembeli barang dan jasa serta tidak memenuhi syarat-syarat sahnya suatu perjanjian, sehingga dalam penerapannya perjanjian yang memuat klausula ini secara sepihak akan bertentangan dengan aturan. Hasilnya adalah penerapan perjanjian sepihak ini banyak menimbulkan kerugian bagi konsumen dikarenakan hanya memberikan keuntungan bagi para penjual atau pelaku usaha saja dan tidak memenuhi syarat sahnya suatu perjanjian. Perjanjian yang menggunakan klausula baku dapat menimbulkan sengketa atau kerugian bagi pembeli sebagai konsumen yang hanya menerima saja jika ada sengketa yang timbul dan dalam hukum perjanjian tidak dilaksanakan berdasarkan kesepakatan dan itikad baik antara ke dua belah pihak yaitu penjual dan pembeli.
Treatment procedures for ideology-based terrorist offenders in Indonesia
Authors: Sukabdi Zora A.
Published: July 2022

Studies on terrorism have increased dramatically since the 9/11 World Trade Center attacks. However, the ways in which terrorist offenders’ rehabilitation should be constructed needs to be examined systematically, regardless of whether the approach used to look at terrorism is clinical or non-clinical. This research was carried out to identify treatment procedures for terrorist offenders based on first-hand experience of terrorism rehabilitators by applying qualitative design. The study involved interviews with terrorist rehabilitators in Indonesia who had been involved in treatment for ideology-based terrorist offenders in Indonesia in a variety of counseling and deradicalization programs. The findings show that the participants mention the presence of modifiable and unmodifiable domains of terrorist offenders. They believe that the domain of terrorism Motivation is likely modifiable, whereas Ideology is more challenging or takes longer to modify, while Capability is unlikely to be modified. The findings also demonstrate that there are nineteen steps for treating modifiable domains and seventeen steps for addressing unmodifiable domains of offenders. The results of this study may provide insights on treatment for offenders with different specifications related to motives, doctrines, attitudes, roles in ideological groups, militancy, and capabilities.

Published: July 2022

Thiopurine exposure from inflammatory bowel disease (IBD) treatment had been associated with a higher risk of lymphoproliferative disorders namely peripheral T-cell lymphoma, as early as 2 years after its initiation. We report a rare case of classical or type 1 enteropathy-associated T-cell lymphoma (EATL) with liver metastasis in a long-standing Crohn’s disease 61-year-old patient treated with azathioprine monotherapy. He presented with acute, severe abdominal pain with cholestatic jaundice and pancytopenia. Colonoscopy showed multiple small, superficial ulcers at the terminal ileum and the biopsy taken was reported as classical EATL, an uncommon gastrointestinal non-Hodgkin’s lymphoma with CD2, CD 3, CD 30, and CD 56 positivity and more than 90% Ki67 proliferative index. Computed tomography (CT) 3-phase liver scan suggested liver metastasis. This case highlights the unusual presentation of classical EATL in non-celiac disease patients and its risk association with thiopurine therapy in IBD.

Published: July 2022

INTRODUCTION: Pedobarography has been widely used in developed countries for few decades. However, in Malaysia it is still in its infancy. Studies showed that the normal values of pedobarography vary between races. To the best our knowledge there is no standard value available for Malaysian or Southeast Asia. This study is designed to measure the pressure values in the normal foot of Malays in Pahang, Malaysia and its difference between different gender and body mass index (BMI). Materials and Methods: A total of 400 feet of adult Malay subjects with no existing diabetes mellitus, lower limb and spine pain or problem are measured using Emed-q100 pedobarography device. Results: 226 (56.5%) were females. 44.5% were with normal BMI followed by overweight (31.5%), and obese (24%). The mean-maximum-peak pressure (MPP) is 509kPa (SD 167) with no significant difference among gender and BMI. Most (38.5%, n=154) of the peak pressure area (PPA) are observed in 1st metatarsal head and big toe region (1MH&T), followed by 2nd metatarsal head (2MH) (34.3%, n=137). In the normal BMI group, 48.3% were in 1MH&T region while in the overweight and obese groups, 42.1% and 43.8%, respectively were in 2MH. This difference is significant (x2(df=8)=36.963, p<0.001). There was no significant difference between PPA and gender. ConClusion: The MPP among Malays in this study was 509kPa(SD 167) and it is not affected by different genders or BMI. The PPA are most commonly fall on 1MH&T. There is a significant shift in the overweight and obese groups to the 2MHT. This finding can be used as initial reference for further studies, in Malaysia particularly.

Published: July 2022

INTRODUCTION: Ultrasound has been widely used to assess thyroid nodules. Although ultrasound elastography has been developed to improve detection of thyroid malignancy, it has received mixed responses. This study aimed to determine the efficacy of ultrasound elastography in detecting malignant thyroid nodules. MATERIALS AND METHODS: Patients with thyroid nodules were assessed using conventional ultrasound and elastography followed by fine-needle aspiration and or hemithyroidectomy. The ultrasound findings were compared with the cytology or histopathology for statistical analysis. RESULTS: Out of 156 nodules from 92 patients included in the study, 12 (7.7%) were malignant and 144 (88.8%) were benign. The elastography was found to be an independent predictor of malignancy (OR 10.35, 95% CI [1.31, 81.6], p = 0.03). Other independent predictors were taller shape and central Doppler pattern obtained using conventional ultrasound. A combination of the three independent predictors was shown to improve the sensitivity of detecting malignant thyroid nodules up to 100%, 95% CI [73.5,100] with NPV of 100%. A new scoring system incorporating the three variables was developed and an algorithm using the scoring system was proposed. CONCLUSION: Thyroid elastography is an independent predictor of thyroid malignancy. Its performance is comparable to conventional ultrasound when used alone and improved when used in combination with conventional ultrasound. It is valuable as screening and risk-stratification tools for patients with thyroid nodules.
On the nonlocal problems in time for subdiffusion equations with the Riemann-Liouville derivatives

Published: July 2022

Initial boundary value problems with a time-nonlocal condition for a subdiffusion equation with the Riemann-Liouville time-fractional derivatives are considered. The elliptical part of the equation is the Laplace operator, defined in an arbitrary N−dimensional domain Ω with a sufficiently smooth boundary ∂Ω. The existence and uniqueness of the solution to the considered problems are proved. Inverse problems are studied for determining the right-hand side of the equation and a function in a time-nonlocal condition. The main research tool is the Fourier method, so the obtained results can be extended to subdiffusion equations with a more general elliptic operator.

This paper investigates inner boundary value problems with a shift for a second-order mixed-hyperbolic equation consisting of a wave operator in one part of the domain and a degenerate hyperbolic operator of the first kind in the other part. We find sufficient conditions for the given functions to ensure the existence of a unique regular solution to the problems under study. In some special cases, solutions are obtained explicitly.

Ultrasonik Akış Ölçümünde Sıcaklık Etkisinin İncelenmesi ve Kompenzasyonu
Authors: GÖKÇEN Alkım , YEŞİL Bahadır
Published: July 2022

Bu makale, elektronik akış ölçüm cihazları için ultrasonik piezoelektrik dönüştürücüler üzerindeki sıcaklık etkilerinin bir

değerlendirmesini sunar. Dönüştürücüler, çift yönlü özelliklerinden dolayı elektrik sinyallerine karşı ultrasonik dalga ve ultrasonik dalgalara karşı elektrik sinyalleri üretir. Fiziksel ortamın sıcaklık dinamiği, ultrasonik dönüştürücülerin elektrik dinamiklerini etkileyen en önemli parametrelerden biridir. Sıcaklık değişimi kaynaklı yanlış sensör okumaları, farklı sıcaklıklar için akış ölçüm işlemi sırasında kalibrasyon hatalarına neden olur. Bu nedenle, dönüştürücü özellikleri üzerindeki sıcaklık etkilerini belirlemek ve genelleştirilmiş bir çözüm oluşturmak için bir test prosedürü ve veri toplama süreci geliştirilmiştir. Başlangıçta, bir akış ölçer gövdesi üzerinde karşılıklı olarak iki özdeş dönüştürücü konumlandırılmıştır. İkinci olarak, gövdeler, farklı akışlar için sinyal ölçümleri almak üzere bir test masasına yerleştirilmiştir. Ultrasonik sinyal ölçümlerini toplamak için bir kablosuz iletişim veri toplama kartı kullanılmıştır. Test işlemi 5 farklı sıcaklık ve 13 debi için tekrarlanmıştır. Veri toplama sonucu elde edilen veri seti MATLAB ortamında değerlendirilip, çalışma koşulları belirlenmiştir ve makine öğrenmesi algoritmalarına dayalı bir sıcaklık etkisi

kompenzasyon modeli önerilmiştir. Bu yöntem, dönüştürücü elemanlarının zaman ekseni bilgilerini dikkate almaktadır. Gerçek akış hızını tahmin etmek için her deney sıcaklık değeri ve Uçuş Süresi (TOF) sinyallerinin ortalama değerleri dikkate alınmaktadır. Böylece, sıcaklık değişimi ve akış ölçümü arasındaki ilişkiyi oluşturmak için makine öğrenmesi algoritmalarından doğrusal regresyon, destek vektör regresyonu (SVR), Gaussian süreç regresyonu (GPR) ve yapay sinir ağları (YSA) kullanılmıştır. Önerilen modelin kompenzasyon performansı 𝑅2, ortalama kare-kök hata (𝑅𝑀𝑆𝐸), ortalama mutlak hata (𝑀𝐴𝐸) ve ortalama kare hata (𝑀𝑆𝐸), gibi hata metriklerinin hesaplanması ile incelenmiştir. Sonuçlara göre, YSA tabanlı kompenzasyon algoritmasının 𝑅2 = 0.95 metriği ile en iyi sonucu verdiği görülmüştür.
