Parental Posttraumatic Stress Disorder and Attunement: Meta-Analysis
Authors: Asanov Julia , Rehman Neelofar
Published: May 2022

Background: Attunement between a primary carer and their infant plays a crucial role in infant brain development, attachment, sense of self and personality development, with long-term effects on risk of future psychopathology. The present study aimed at 1) identifying a comprehensive definition of attunement and 2) investigating parent-infant attunement in the context of parental posttraumatic stress disorder (PTSD).
Subjects and Method: Following PRISMA guidelines, a systematic review of the literature was conducted on parental PTSD and parent-infant attunement. Eligible studies were prospective, quantitative, published in peer-reviewed journals, included normal samples and samples with PTSD along with attunement variables, reporting correlational data, with mothers aged 16 or older and infants aged 0-18 months. 48 articles were examined in full-text and 18 selected for analysis. A National Heart, Lung, and Blood Institute (NHLBI) quality assessment tool was used to assess the quality of selected studies. Pooled effect sizes were calculated separately for positive and negative attunement variables under the random effects model, using comprehensive meta analysis (CMA).
Results: Analysis failed to reach statistical significance. The pooled effect size for parental PTSD and negative attunement was positive and small. The pooled effect size for parental PTSD and positive attunement was negative and small.
Conclusion: Due to the high heterogeneity among the included articles and statistically non-significant effect sizes, results need to be interpreted with caution. However, the results indicate that the presence of PTSD symptoms is likely to influence parents’ capacity to attune to their infants. Limitations and implications for future research and clinical practice are discussed.

Authors: Rahayu Putu Sri , Tamtomo Didik Gunawan , Budihastuti Uki Retno
Published: May 2022

Background: Injectable contraception is the most popular contraceptive method in Indonesia with a user percentage of 63.71% of the coverage of modern family planning users. In addition to the benefits and practicality of its use, this method also has various negative impacts that can endanger the health of the acceptor. This study aims to explore and describe the acceptor's response to the negative impacts experienced as a form of responsibility for the health of the acceptor.
Subjects and Method: This study was conducted using descriptive qualitative method with triagulation analysis technique that connects empirical facts. The dependent variable is injectable family planning. The independent variables are responsibility, patriarchal culture, and decision making. The study was conducted on 18 informants who are injection family planning acceptors in Timor Tengah Selatan Regency.
Results: The informants do not mind experiencing the negative impacts of using injectable contraceptives and prioritize the benefits and practicality of their use. The low level of education of informants is a problem in receiving and digging information. Limited access to information is also hindered by the lack of infrastructure to reach health facilities. The high pressure of patriarchal culture is one of the decision-making factors and the high number of injecting family planning users.
Conclusion: The acceptor's lack of information regarding the contraceptive method used is a barrier in responding to the negative impacts experienced.
The Impact of Exposure to Information Technology in Determining Women’s Knowledge of Complication during Pregnancy, Labor, and Postnatal
Authors: Nurmawati Erna , Napitupulu Joseph Gabriel , Sugiyarto Teguh
Published: May 2022

Background: Indonesian Demographic Health Survey (IDHS) 2012 reveals that Maternal Mortality Ratio (MMR) in Indonesia is 359 per 100,000 live births or increase from 228 per 100.000 live births in 2007. Compared to the other ASEAN countries, the risk of maternal death in Indonesia is also relatively high, 1 in 65 mothers. Some researches depict that maternal death is caused by inadequate care during pregnancy and delivery (labor). This condition is caused by the availability of health facility or improper health seeking behaviors. Considering the crucial role of knowledge to determine people behaviors, this paper is aimed to discuss the impact of information technology to shape people knowledge on maternal health.
Subjects and Method: Some variables in Indonesian Health Demographic Survey 2017, identify the subject’s  knowledge on danger sign of complication during pregnancy, labor/delivery and postnatal periods. In digitalized era, the knowledge may come from many sources. Therefore, the discussion will focus on the impact of subject’s  accessibility and utilization of internet, mobile phone, radio, TV and newspaper in shaping knowledge of maternal health.            
Results: This study found that women with primary education (OR= 1.57; p < 0.001), did not access the internet (OR= 2.49; p= 0.110); the frequency of accessing the internet for health (OR= 1.94; p= 0.083) increased women's knowledge about dangerous signs during pregnancy. While not reading newspapers (OR= 0.66; p < 0.001); not watching television (OR= 0.66; p<0.001), having or not having television (OR= 0.59; p < 0.001); do not have a mobile phone (OR= 0.64; p<0.001); not having a radio (OR= 0.88; p < 0.001) decreased women's knowledge of the danger signs during pregnancy, but this result was statistically significant.
Conclusion: This result reveal that the effectiveness of internet to influence women knowledge on maternal health must be improved because of its potential in this digitalized era and the progressive trend of internet penetration in Indonesia.
A Procedure to Quantify the Variability of Geotechnical Properties
Authors: Folle Daiane , Costa João F. , Koppe Jair C. , Zingano André C.
Published: May 2022

The geotechnical properties of soil should be considered for several civil engineering purposes. Geotechnical informa- tion is used for urban planning, environmental management, slope stability analysis, and foundation design, among others. Given the importance that geotechnical information assumes in several engineering applications, geotechnical mapping is deemed rele- vant. Methods for integrating field tests and quantifying estimate uncertainty in the construction of these geotechnical maps is preferably used in the decision-making process. A methodology to build this kind of maps is proposed based on geostatistical sto- chastic simulation. Maps covering an area of 4 km2 were built, based on the information derived from 141 boreholes, where stan- dard penetration tests (SPT) were carried out. Sequential Gaussian simulation was used for building these maps, since it reproduces data statistics and spatial continuity. The soil resistance to penetration of panels of 100 x 100 m2 was estimated and the estimation error was calculated. The results demonstrate the appropriateness and usefulness of the methodology for mapping geotechnical attributes.
Experimental Investigation of Mechanical Damage in Geogrids
Authors: Sieira Ana C. , Sayão Alberto S.
Published: May 2022

This paper presents the results of a comprehensive experimental program for investigating the influence of mechanical damage on the load-displacement behavior of geogrids. Unconfined tension tests, pullout and direct shear tests were carried out on intact and damaged specimens. Natural or artificial damages were produced either by imposing heavy compaction procedures in the laboratory or by simply cutting one or more geogrid elements. It is concluded that natural damage in the geogrid may be more pronounced when aggressive compaction methods are used with coarse grained soils. Fine grained soils did not show a significant strength reduction even when subjected to heavy compaction in the laboratory. Under pullout loading, artificial damage was also noted to be of little significance for fine soil (silty clay). Rupture of the geogrid’s transverse elements led to a significant pullout strength reduction. These transverse elements are responsible for anchoring the geogrid within the soil mass. However, under unconfined tensile load, these transverse elements are responsible only for the grid’s geometrical configuration and their rupture did not induce a significant strength loss. In direct shear, the position of the geogrid relative to the potential failure surface was shown to be an important factor.
Geo-Engineering Education and Training. The Past and the Future
Authors: Oliveira Ricardo
Published: May 2022

A brief background on education and training in Soil Mechanics, Rock Mechanics and Engineering Geology is presented, highlighting some facts which influenced the development of these sciences. The interplay between them is stressed. The International Societies (ISSMGE, ISRM and IAEG) role in promoting education at different levels is emphasised. The performance of scientists and engineers teams from different backgrounds for the study, design, construction and rehabilitation of major infrastructures and for the solution of many geoenvironmental problems is illustrated. These disciplines are taught today in University undergraduate courses in Civil Engineering, Geological Engineering and Geology and graduate courses are tending to be jointly attended by professionals coming from these three branches. The Bologna Declaration introduced significant modifications in University education and most European countries have already adjusted their education systems to its requirements. Based on some principles of this declaration, perspectives are presented concerning future education and training in geoengineering.
Slope Failure Reanalysis of a Dilatant Dense Sand from CPTU and Laboratory Tests
Authors: Karim U.F.A. , Menkveld A.
Published: May 2022

Geotechnical properties of dense to very dense sands at Channel Island Harbor in Oxnard, California, are re-evaluated after slope failures to select appropriate strength parameters for remedial and extension works. The revetment is excavated at a slope of 2:1 (horizontal: vertical) in estuarine and dune sands and covered with a geotextile filter and armor rock. Reanalysis of the slope stability explores laboratory and in situ strength conditions of peak, constant volume and residual angles for the sands. A stress-dilatancy theory provides the framework used in re-characterization of the soil and observed slope failure mechanisms. Effective friction angles are recommended for further slope stability analysis at that location.
Modeling the Influence of Biodegradation on Sanitary Landfill Settlements
Authors: Machado Sandro L. , Carvalho Miriam F. , Vilar Orencio M.
Published: May 2022

This paper presents a mathematical model to reproduce long term or secondary settlement of sanitary landfills. Sec- ondary compression is assumed to be commanded by two main processes: mechanical creep compression and the biodegradation of waste. The model introduces a biodegradation parameter that relates mass loss with volumetric variations. The biodegradation of Municipal Solid Waste (MSW) organic matter was represented through gas generation, modeled as a first order decay process. The gas generation was transformed into mass loss and used to evaluate biodegradation settlements through a mass balance equa- tion. Some qualitative approaches concerning the time origin of secondary compression processes were addressed and used in the simulations. Strategies for obtaining model parameters are also presented and the main implications of biodegradation on settle- ment are discussed. The results predicted by the model are compared with laboratory and sanitary landfill data and reveal high levels of agreement between measured and calculated values.

Sanatsal İmgeden Tıbbi İmgeye: Salpêtrıère Fotoğrafları ve Histerik Kadın Bedeninin İnşası
Authors: TAŞ Tuğba
Published: May 2022

Bu makalenin amacı, kültürün her alanına yayılmış olan histerik kadının görsel imgesinin tarihsel kökenlerini ve direngenliğinin nedenlerini ortaya çıkarmaktır. Bu doğrultuda Michel Foucault’nun soykütük yöntemi kullanılacaktır. Kökeni Hipokratik metinlere dayanan histeri tanımının, görsel bir imge olarak yaygın kullanıma girmesi 19. yüzyıl tıbbi pratikleri içinde fotoğrafın kullanılmasıyla başlamıştır. Fotoğrafı gerçeğin dolaysız bir kopyası olarak gören pozitivist yaklaşımı benimseyen psikiyatristler ve nörologlar, bedenin yüzeyine ilişkin izlenimci değerleri kullanıma sokmuşlar ve görünmez bir patoloji olarak ele aldıkları histeriye kanıt oluşturmak için fotoğrafı kullanmışlardır. Bu yaklaşımın en tipik örneğiyle Jean Martin Charcot’nun (1825-1893) yönetimindeki Salpêtrière Hastanesi’nde üretilen fotoğraflarda karşılaşırız. Paris’teki Salpêtrière Hastanesi’nde fotoğraf makinesinin bilimsel araştırma adına kullanılmasıyla, Foucault’nun kavramlarıyla söylersek, 19. yüzyıl klinik dispositifi içinde histeriye ilişkin güçlü bir bilgi alanı ve söylemsel çerçeve oluşturulmuştur. Bu makalede söz konusu çerçevenin diğer bir kurucu unsurunun fotoğraflarla eş zamanlı dolaşımda olan veya onları önceleyen sanatsal imgeler olduğu iddia edilmiştir. Bu nedenle makalede, Théodore Géricault’nun deli kadın portreleri, John Everett Millais’nin Ophelia (1851-1852) tablosu, Tony Robert-Fleury’nin Pinel à la Salpêtrière (1876) tablosu, André Brouillet’nin Une leçon clinique à la Salpêtrière (1887) tablosu ile Charcot ve Richer’in Les Démoniaques dans l’art (1887) kitaplarında yer verdikleri içine “şeytan giren kadın” ya da “cadı kadın” imgeleri Salpêtrière’de üretilen fotoğraflarla ilişkisi içinde ele alınacaktır.

Sungai Bedadung merupakan salah satu sungai utama di Kabupaten Jember. Sepanjang aliran sungai segmen Kecamatan Sumbersari dan Kecamatan Kaliwates ini terdapat aktivitas antropogenik berupa perumahan padat penduduk dan lahan pertanian yang menghasilkan limbah organik maupun an-organik. Kegiatan tersebut  yang berhubungan langsung ke sungai berpotensi menambah beban pencemaran. Beban pencemaran yang dihasilkan dapat berpotensi menurunkan kualitas air. Tujuan penelitian ini yaitu menganalisis kualitas air dan laju deoksigenasi serta reoksigenasi Sungai Bedadung Segmen Kecamatan Sumbersari-Kaliwates menggunakan metode Streeter-Phelps. Pengambilan data berupa debit air, TSS, DO, BOD, dan COD dengan grab sampling. Hasil perhitungan laju deoksigenasi dan reoksigenasi disintesis dengan metode deskriptif kuantitatif. Nilai TSS dan DO memenuhi baku mutu kelas I akan tetapi nilai BOD dan COD tidak memenuhi baku mutu kelas I. Nilai rata – rata laju deoksigenasi (rD) dan reoksigenasi (rR) secara berurutan sebesar 0,798 mg/L.hari dan 2,753 mg/L.hari. Nilai laju reoksigenasi lebih besar dari pada nilai laju deoksigenasi. Kondisi tersebut mengindikasikan bahwa kemampuan Sungai Bedadung berjalan dengan baik dalam reduksi bahan organik secara alami. Besar kecilnya rR dan rD dipengaruhi oleh konstanta reoksigenasi, konstanta deoksigenasi, dan profil hidraulik sungai.

Laparoscopic surgical treatment of median arcuate ligament syndrome with the retrograde division technique: a case report
Authors: Fahri Yetisir , Afruz Babayeva , Kerim Güzel
Published: May 2022

Median arcuate ligament syndrome is a rare entity. This clinical condition develops by compression of the root of a celiac artery with the median arcuate ligament. The typical triad of this syndrome is the following; abdominal discomfort and pain, especially after a meal, and weight loss. In diagnosis, other causes should be ruled out and compression must be demonstrated by any type of imaging method. The main principle of treatment is cutting down the median arcuate ligament. A 54-year-old woman presented with untreatable recurrent abdominal pain and was diagnosed with median arcuate ligament syndrome by imaging with angiographic computed tomography. This patient was operated on. We performed laparoscopic division of median arcuate ligament with the retrograde surgical dissection technique. The patient was discharged from the hospital without any complaint on the third day after surgery. She was still symptom-free after 12 months. The laparoscopic retrograde dissection approach is a safe and feasible treatment modality for median arcuate ligament syndrome.

Published: May 2022

Aeronautical applications of morphing technologies are continued to increase their popularity and wide spread application during last years. The technology takes place in not only military, but also civil applications that aims providing superior performances to manned or unmanned aircraft than conventional configurations. However, multidisciplinary approach is required for an aerial vehicle to have ultimate outcome from such an application due to existence of interdisciplinary interactions. Therefore, this research aims to investigate effects of morphing wingtip application on longitudinal and lateral-directional stabilities of a fixed-wing unmanned aerial vehicle, which have remarkable effect on autonomous control performance considerations. In this article, morphing wingtip refers to folding the wing from a determined spanwise location with a dihedral angle. With the aim of the study, wingtips of an unmanned aerial vehicle were folded with 15, 30 and 45 degrees of dihedral angles to be compared with original non-dihedral design. Longitudinal and lateral-directional characteristics of new variations were evaluated in terms of stability derivatives by means of linearized equations of motion that were also presented in state-space representation. Aerodynamic impacts of each variation were assessed by means of computational results obtained from analyses with three-dimensional panel method. Furthermore, taking inertial changes into consideration, concluding remarks on both longitudinal and lateral-directional stability derivatives were presented for each configuration.

Implementation of Principal Component Analysis and Learning Vector Quantization for Classification of Food Nutrition Status
Authors: Pardede Jasman , Athifah Hilwa
Published: May 2022

Balanced nutrition is very good in the process of child development. During the COVID-19 pandemic, consuming a balanced nutritious diet can keep a child's immune system from transmitting the virus. In determining the nutritional content of children's food during the pandemic, a classification of the nutritional content of children's food is carried out by applying the principal component analysis (PCA) dimension reduction method and the learning vector quantization (LVQ) classification method. The data used in this study amounted to 1168 data with 25 indicators of food nutrients. From the tests that have been carried out, the combination of the PCA-LVQ method produces an average accuracy of 58% with the highest accuracy of 60%. In addition, this study also compares the performance of the PCA dimension reduction method, independent component analysis (ICA) and factor analysis (FA) on the LVQ classification process. The final result of testing the three methods is that the FA method takes the fastest time, which is 4.10434 seconds and the PCA method produces the highest accuracy, which is 58.2%

This study used Corona Virus Disease-19 (Covid-19) data in Indonesia from June to August 2021, consisting of data on people who were infected or positive Covid-19, recovered from Covid-19, and passed away from Covid-19. The data were processed using the adaptive LMS algorithm directly without pre-processing cause calculation errors, because covid-19 data was not balanced. Z-score and min-max normalization were chosen as pre-processing methods. After that, the prediction process can be carried out using the LMS adaptive method. The analysis was done by observing the error prediction that occurred every month per case. The results showed that data pre-processing using min-max normalization was better than with Z-score normalization because the error prediction for pre-processing using min-max and z-score were 18% and 47%, respectively.

The following credit card records were used in this study of 284.807 transactions made by credit card holders in Europe for two days from the Kaggle dataset. This is a very poor data set, having 492 transactions, an imbalance of only 0.172% of the 284.807 transactions. The purpose of this study is to obtain the best model and then simulate it by electronically detecting unauthorized financial transactions in bank payment systems. The dataset for this study is unbalanced class data with 99.80% for the major class and 0.2% for the minor class. This type of class-imbalanced data problem is solved by applying method a combination of minority oversampling techniques using Synthetic Minority Oversampling Technique (SMOTE). To determine the most appropriate and accurate classification in solving class balance problems, comparisons were made with the Random Forest Classifier (RFC), Logistic Regression (LGR), and Gradient Boosting Classifier (GBC) algorithms. The test results in this study are the Random Forest Classifier (RFC) algorithm is better than other algorithms because it has the highest accuracy the percentage of data-train is 100% and data-test is 99.99% and the evaluation of the AUC score as a result of algorithm testing is 0.9999.

Abstract – Expert systems can be applied to the classification of dengue fever. Dengue is a serious disease that can be fatal if not diagnosed and treated properly. Headache, muscle aches, fever, and rash are some of the most prevalent symptoms. Dengue fever is a disease that is endemic in various South Asian and Southeast Asian nations. Dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome are the three types of dengue (DSS). Currently, these diseases may be classified using a machine learning approach with dengue symptoms as the input data. This study proposes implementing an Artificial Neural Network (ANN) with the Backpropagation (BPNN) algorithm as the classifier to categorize dengue types, divided into three categories: DF, DHF, and DSS. The dengue symptoms are represented by 21 attributes in the dataset. It was gathered from 110 patients. Cross-validation with k-fold 3, 5, and 10 were applied as the evaluation method. Three parameters were obtained to evaluate the ANN classification method: precision, recall, and accuracy. These were used to justify the most optimal performance. Cross-validation using k-fold 3 produced the best evaluation results, with precision, recall, and accuracy values of 97.3%, 97.3%, and 97.27%, respectively.
