Construction in Antarctica and South Georgia: delicate works in a pristine environment
Authors: van Doremaele Koen , Gibert-Suñé Emma , Meijer Emiel
Published: October 2021

This paper describes the design and construction works of the new wharves in Rothera in the Antarctic Peninsula and in the Sub-Antarctic island of South Georgia, two exceptionally isolated and environmentally protected locations with extreme climate conditions. Construction in such pristine locations requires special measures and an integrated design, preparation and construction approach. Minimum impact is achieved by re-using existing materials and reducing the amount of new materials required. Strict biosecurity and environmental monitoring has been in place. Design choices were focused on limiting the extent of the works on site by pre-fabrication of the structural elements in Europe, which also ensures the quality standards can be achieved. Low maintenance and durability are also keys aspects to the design choices.
Simplified approach for the seismic analysis of precast girder bridges with gap
Authors: Ayoub E. F. , Youakim M. , Nady P.
Published: October 2021

Precast girder bridges are very attractive structural systems to bridge engineers due to their construction rapidity. In their deck arrangement a gap is introduced between the precast girders and the inverted pier cross head. Under longitudinal seismic effect the gap can be closed and the superstructure movement will be locked by the web of the pier cross-head. Usually a rigorous and sensitive non-linear time history analysis will be required for this type of structures. In this paper, a simplified approach will be introduced to estimate the base shear force transmitted to the bridge substructure under seismic loading. In the present approach the modelling of the elastomeric bearing element stiffness is modified in such a way that under earthquake loading the relative displacement between top level and bottom level of bearing equals to the gap value. The seismic analysis with slight, moderate and sharp earthquake accelerations is performed based on the response spectrum analysis as presented by AASHTO LRFD.
Ground motion spatial variability and cable-stayed bridges: do we need to consider the asynchronous motion?
Authors: Efthymiou Eleftheria , Camara Alfredo
Published: October 2021

Cable-stayed bridges are landmark structures and key parts of transportation networks worldwide. It is of vital importance that their integrity is ensured even under very large earthquakes. The spatial variability of the ground motion could be a significant aspect of the seismic behaviour of long-span cable-stayed bridges due to the differential movement of the pylons, which may lead to an amplified seismic response and increased damage in the pylons. The purpose of this paper is to examine the effect of the spatial variability of the ground motion on the seismic response of cable-stayed bridges with H-shaped pylons and various span lengths. Focus is placed on the pylons of the bridges because the constitute key members for the overall stability and structural integrity of the bridge. The study explores how important the spatial variability is in the seismic response of cable-stayed bridges by considering two different orientations of the structures with respect to the seismic fault in an extensive program of non-linear response-history analyses.
Investigation on the reasonable area of energy-dissipation bars for hybrid rocking columns
Authors: Bao Zehua , Zhong Xueqi , Li Jianzhong
Published: October 2021

In recent years, hybrid rocking columns have drawn more and more interests from researchers, due to their self-centering capacity. The energy-dissipation bars, which are generally applied at the rocking joints of hybrid rocking columns, could improve their energy dissipation capacities. Thus, the reasonable reinforcement ratio of energy-dissipation bars is much required for engineering applications. To determine the reasonable reinforcement ratio of energy-dissipation bars, a numerical investigation is conducted in this paper based on nonlinear time-history analysis. The analysis results show that a reasonable reinforcement ratio of energy-dissipation bars can effectively reduce seismic displacements of the hybrid rocking columns, without excessive residual deformations. Further, the reasonable reinforcement ratio of energy-dissipation bars for hybrid rocking columns with different periods is proposed in this paper.
Numerical analyses on mechanical performance of flat buried approach slab and soil deformation
Authors: Xue Junqing , Xu Dong , Tang Yufeng , Briseghella Bruno , Huang Fuyun , Nuti Camillo
Published: October 2021

The vulnerability problem of expansion joints could be fundamentally resolved using the concept of jointless bridges. The longitudinal deformation of the superstructure can be transferred to the backfill by using the approach slab. The flat buried approach slab (FBAS) has been used in many jointless bridges in European countries. In order to understand the mechanical performance of FBAS and soil deformation, a finite element model (FEM) was implemented in PLAXIS. Considering the friction between the FBAS and soil, the buried depth, the FBAS length and thickness as parameters, a parametric analysis was carried out. According to the obtained results and in order to reduce the soil deformation above the FBAS, it is suggested to increase the friction between the FBAS and sandy soil, and the buried depth of FBAS. Moreover, it should be paid attention to the vertical soil deformation and the concrete tensile stress of FBAS in pulling condition.
Evaluation of the contact area of lorry tyres in Eurocode’s fatigue load model 4 (FLM4)
Authors: Hengeveld Sjoerd , Vervuurt Adri , Maljaars Johan
Published: October 2021

Fatigue considerations dominate the design of new, innovative steel bridge decks. Weighing bridge deck al- ternatives requires representative values for contact areas and contact stress distributions of the tyres of heavy vehicles. Fatigue load model 4 in the Eurocode EN 1991-2 (FLM4) provides tyre contact areas together with a set of axle loads. The literature survey presented herein shows that the length of the contact area in FLM4 is too large.

The consequence of using a more realistic – i.e. shorter – tyre contact length together with a non-uniform contact stress distribution that is observed in practice, is that the contact stresses increase. As a result, the load effect and the fatigue life of some bridge deck details reduce, as is shown by the analyses presented in this paper. A method is proposed for determining an updated tyre contact area for the FLM4 Eurocode model, leading to a more realistic fatigue damage analyses.
Development of ductile cast-iron bridge slabs for onsite replacement
Authors: Akamatsu Shinsuke , Tobinaga Hironobu , Oshima‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌ Kunihiro , Nohara Norihiro
Published: October 2021

Most of the road bridges in Japan were constructed in the 1960s and 1970s, and many of them have been in service for more than 50 years. The reinforced concrete slabs of such bridges have been damaged and deteriorated by heavy traffic. Although these slabs have already been reinforced with steel plates, they have deteriorated further and need to be replaced.

The renewal of reinforced concrete slabs leads to increase of dead load, the fatigue damage at welds has not been completely solved in the case of steel slabs, and the social loss due to long-term road closures at the renewal construction of the slabs on urban highways. Therefore, there is an urgent need to develop an alternative slab that is lighter in dead weight, has good fatigue resistance, and can be installed rapidly.

The proposed slabs in this paper are made of ductile cast-iron instead of mild steel. Ductile cast-iron bridge deck can be light-weighted like mild steel, can show high fatigue resistance with improved residual stress and detail by integrally forming into complex shapes, and can be rapidly installed to the existing bridges by bolts.

The Hanshin Expressway has been conducting research and development for the practical application of ductile cast-iron slabs. This paper will introduce a ductile cast-iron deck, and will shows the study results of the details of the slab panels, the slab-to-slab connection method, and the slab-to-girder connection method.
Testing of composite girders with coiled spring pin shear connectors
Authors: Hällmark Robert , Nilforoush Rasoul , Vestman Victor , Collin Peter
Published: October 2021

Today, steel girder bridges with concrete deck slabs are generally constructed as steel-concrete composite structures, to utilize the material and the structural parts in an efficient way. However, many existing bridges constructed before the early 1980´s were designed without shear connectors at the steel-concrete interface. With increasing traffics loads and higher amount of load cycles, there is sometimes a need to strengthen these bridges. One way to increase the bending moment capacity is to create composite action by post-installation of shear connectors. The authors have studied the concept of strengthening by post-installed shear connectors, with a focus on a connector called coiled spring pin. This paper presents the results from the first beam tests performed with this kind of shear connector. In line with the previous push-out tests, the test results indicate a very ductile shear connection, with a potential to be a material- and cost-efficient strengthening alternative.
Strengthening old steel railway bridges: a review
Authors: Venturi Giorgia , Simonsson Peter , Collin Peter
Published: October 2021

Strengthening old bridges is an increasingly relevant strategy for risk prevention and operation continuity in management of infrastructures. Transportation networks are subjected to progressively stricter environmental and load conditions, leading to a growing number of deficient structures, also due to aging and deterioration. However, employable resources are finite, from both economical and environmental points of view. For these reasons, strengthening opportunities should be considered as a viable option, improving bridges behaviour with low economical and environmental impact. With this perspective, a selection of some of the most interesting strengthening techniques for old truss railway bridges is presented. To address effective solutions, the most frequent problems in old truss railway bridges are first presented. Literature analysis and experts’ interviews were conducted and compared to results obtained from a representative bridge cluster. Different solutions addressing highlighted problems are then collected and qualitatively evaluated, in terms of efficacy on structural behaviour and typical construction requirements. Finally, general remarks and recommendations based on collected evidence are presented.
Climatic advantages of the spread of timber constructions in peripheral regions - the case of southern Switzerland
Authors: Miccoli Stefano , Frangi Andrea
Published: October 2021

The aim of this paper is to investigate the methods available for encouraging the spread of timber constructions in small, peripheral regions such as southern Switzerland. Since 2005, Switzerland has witnessed a major increase in the number of timber constructions, mainly due to the new fire prevention regulations and to the climate and energy goals that the country wants to meet in the near future. This growth has been less significant in southern Switzerland. Data given by the Federal Office for the Environment (FOEN) shows the climatic advantages of the spread of timber constructions. Therefore, the opportunities for increasing the growth of such constructions in southern Switzerland have been researched. In order to identify and take advantage of the unique features of the use of wood in this region, two recent timber buildings, the Nordic Ski Centre by Durisch & Nolli, and the House in Ludiano by Tocchetti & Pessina, are analyzed and presented in this paper. The case of southern Switzerland can be a model for the spread of timber constructions in other similar regions.
Engineering of a contemporary version of the stone arches of the "Pont des Trous" in Tournai
Authors: Duchêne Yves , de Ville de Goyet Vincent , Gens Frédéric
Published: October 2021

As part of the works on the Seine-Scheldt link, the Scheldt is to be expanded to CEMT class Va at the Tournai crossing. The main works comprise the widening of the Scheldt river and the central arch of the historic bridge called “Pont des Trous” – “Bridge of the Holes”. The choice of replacing the bridge has gone to a triple arch in stone masonry with a main span of 20 m for a height of 15 m and a thickness of 40 cm, closer from a sculpture. Due to its very small thickness and corresponding self-weight, accurate estimation, with wind tunnel tests by University of Liège, of the wind effects is of utmost importance for the verification of masonry and especially the joints openings. Nonlinear finite element calculations considering cracking and opening of joints, using Finelg software, show that the joints should be glued to ensure the stability. Finally, by political decision, this triple arch project was abandoned and replaced by a more conventional structure.
Bi-direction evolutionary structural optimization in seismic design of braced steel frame tall buildings
Authors: Jinlun Cai , Xin Zhao , Junchen Guo
Published: October 2021

The traditional design method of high-rise building structure often has a lot of redundancy, on the one hand, it consumes a lot of engineering materials and energy, and there is a large space for optimization; on the other hand, due to the failure of rational and effective use of structural materials, it may lead to increased safety risks. In addition, the traditional design method is based on experience judgment and manual iteration, so the design workload is heavy and the design efficiency needs to be improved. In this paper, based on the bi-directional evolutionary structural optimization, the optimal seismic design of a braced steel frame tall building is carried out. The results show that the algorithm can reasonably distribute the materials to each member, and achieve an efficient seismic optimization design.

This paper presents the ongoing benchmark results of IABSE Task Group 3.1. The task of this working group is to create benchmark results for the validation of methodologies and software programs developed to assess the stability and the buffeting response of long span bridges. Indeed, accurate estimations of structural stability and response to strong winds are critical for the successful design of long-span bridges. While the first results of the benchmark, dealing with a section approach, have been already published, in this paper the ongoing activity and results of the task group are presented. The topic of these results is the numerical response of a full-bridge model under the actions of a multi-correlated wind field both in terms of aeroelastic stability and buffeting response.
INDIGENOUS EDUCATION AS A NATIONAL PROJECT IN MEXICO 1910–1920S
Authors:   Russian State University for the Humanities, Molodchikova Tatiana S.
Published: October 2021

This article focuses on the study of the characteristics of the sociocultural policy of the Mexican state in relation to the indigenous population in the 1910–1920s – a period of revolutionary transformations and the building of a “new type” society in Mexico. During the Mexican Revolution, the “Indian question”, along with the work and agrarian question, became a key point in the policy of the revolutionary governments. The importance of the popular education issue in Mexico in the first post-revolutionary years was determined by the fact that three quarters of the population did not have access to the state education system, as well as by the existence of numerous ethnosocial groups, territorially and culturally separated from each other and the rest of the country. It should be emphasized that the 1910–1920s were marked by the genesis of numerous theories of the unification of Mexican society and the integration of the native population, as well as by the introduction of modern, experimental teaching methods (in particular, the rationalist and socialist school), the purpose of which was to translate into reality the Revolution ideals and build a new Mexican society. The policy of integrating the native population of Mexico was carried out through numerous educational projects, which include the “cultural missions”, “Indigenous Student House”, “House of the People” and others. Analysis of archival materials related to the preparation of the first «cultural missions», as well as the functioning of educational institutions designed to educate the indigenous student, made it possible to identify the characteristics of the socio-cultural integration of the rural population of Mexico during the above period.

Liquid Smoke Fractionation from Dry Distillation of Styrofoam Board Waste to Produces Liquid Fuel
Authors: Anom I Dewa K
Published: October 2021

Styrofoam waste is difficult to be decomposed by bacteria or microorganisms. Therefore it takes a long time to be decomposed naturally. Styrofoam waste, in general, is a big problem for the survival of living things on earth because there are quite a lot of them. So, if not handled properly can cause environmental pollution. Styrofoam waste is inorganic waste composed of polymers derived from chemicals. Additives from styrofoam are harmful to humans because they are carcinogenic. This study aims to utilize Styrofoam board waste into liquid fuel. Liquid fuel from styrofoam waste has been made successfully through dry distillation and fractionation methods. The result of fractional distillation is 42.00% liquid fuel. Based on the physical properties tests that have already been carried out, including the density test, viscosity,  flash point, boiling point, calorific value, and octane number, it turns out that the liquid has characteristics close to the standard gasoline fuel. The MS spectra and the GC chromatogram show that the liquid fuel consists of a mixture of hydrocarbon compounds, namely acetone 0.23%, acetic acid 0.40%, benzene 2.82%, toluene 3.56%, heptane 1.04%, 1-octene 0.26%, butyl ester 4.92%, 2,4-dimethyl-1-heptane 0.32%, p-xylene 13%, the compound with the highest composition was styrene 73.45%.

REDUCTION OF CORROSIVE ACTIVITY OF OPERATING OIL IN THE BENZENE DEPARTMENT OF COKE PRODUCTION OF PJSC «ARCELORMITTAL KRYVYI RIH» © I.I. Sikan, R.V. Karenov, N.V. Mukina, S.N. Solonko (Coke production of PJSC «ArcelorMittal Kryvyi Rih», 50095, Dnipropetrovsk region, Kryvyi Rih, Kryvorizhstal str., 1, Ukraine), L.P. Bannikov, PhD in technical sciences (State Enterprise "Ukrainian State Research Coal Chemical Institute (UHIN)", 61023, Kharkov, Vesnina st., 7, Ukraine) This paper analyzes and formulates the optimal technological solutions to reduce the corrosiveness of the absorption oil. The problem of reducing the corrosiveness and the ability of the absorbing oil to form the precipitates becomes especially actual in view of the introduction in the technological scheme of a new tube furnace ThyssenKrupp (Germany) for heating the absorption oil in the benzene section. All major work has now been completed at this facility, and soon the new furnace will be commissioned, which should significantly improve the regeneration of the absorption oil. Research of quality indicators of fresh oil and potentiodynamic testing of its water extracts has been fulfilled. To verify that the tube furnace tube material meets the requirements, a spectral analysis of a sample of the damaged tube was performed. The suspended solids of the circulating oil were observed under a microscope at a magnification of ×250. It was revealed that recycled absorption oil can lose quality as a result of tube furnace wear, frequent stoppages for repairs and watering of oil with coke oven gas condensate in scrubbers. Exit from the state of watering occurs during the operation of the distillation department due to "steaming" in the column. As a result, the concentration of salts in the oil occurs and, as a result, its corrosiveness increases. Oil watering in the distillation column occurs when the heating temperature drops. Before starting a new tube furnace, it is advisable to renew the entire working volume with fresh oil with preliminary flushing of the equipment. This will make it possible not to water it in the future during the smooth operation of the distillation and to maintain the proper quality of the absorption oil. Keywords: capture of benzene hydrocarbons, absorbing oil, distillation column, regeneration, tubular furnace, corrosiveness, survey, watering, suspended particles, aggregation.

Natural Disasters and Green Party Support
Authors: Hilbig Hanno , Riaz Sascha
Published: October 2021

A growing literature shows that extreme weather events induce pro-environment attitudes. We examine the political effects of a severe flood shortly before the 2021 German federal election. Drawing on about 600,000 survey responses and electoral data, we assess how flooding affected (i) the perceived salience of climate change, (ii) self-reported Green Party support, and (iii) Green Party voting in federal elections. We find that even severe local flooding had little to no effect on these outcomes. Additional evidence supports two mechanisms underlying this finding: nationwide rather than local effects of severe disasters, and voter demands for disaster relief rather than climate change prevention. We test the former mechanism using a regression discontinuity design and find that the flood increased nationwide Green Party support, although this effect persists for only two weeks. Our results shed new light on the precise duration and geographic scope of the political effects of natural disasters.

Published: October 2021

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of DENN/MADD domain containing 1C, encoded by DENND1C when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, DENND1C expression was correlated with recurrence-free survival in basal subtype breast cancer, a molecular subtype sharing significant overlap with triple negative breast cancer. DENND1C may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.

Jiwa merupakan salah satu komponen penting karena ketika jiwa tidak mendapatkan porsi dalam kepuasan maka akan mengakibatkan gangguan berupa setres depresi dansebagainya. Disini Rabiah Al-Adawiyah muncul dengan praktek spiritualnya untuk mengobati masalah kejiwaan dan spriritualitas.. Rabi’ah adalah orang pertama yang mampu membuat pembagian mahabbah (cinta) sehingga lebih mendekat pada perasaan. Cinta menurut Rabi’ah ada dua macam, yaitu: cinta karena dorongan hati belaka, dan cinta yang didorong karena hendak membesarkan dan mengagungkan. Rabi’ah mencintai Allah karena ia merasakan dan menyadari betapa besarnya nikmat dan kekuasaan-Nya, sehingga cintanya menguasai seluruh lubuk hatinya. Ia mencintai Allah karena hendak mengagungkan dan memuliakan-Nya. Selayaknya orang yang sedang dimabuk cinta, Rabi’ah sering kali menciptakan syair-syair cinta yang ditujukan kepada Allah. Kita mengetahui bahwa permasalahan jiwa terutama cinta merupakan hal penting dan berpengaruh sangat besar kedalam jiwa, banyak cinta yang membutakan, karena cinta memainkan peran penting dalam kehidupan. Potensi dan frekuensi cinta berubah sesuai dengan situasi dan kondisi. Cinta juga berfungsi unutk mengikat hubungan antar manusia dan juga menghubungkan kepada Tuhan. Pemahaman yang salah akan berakibat ke berbagai macam aspek.

SYAP1 expression associates with survival in triple negative breast cancer.
Authors: Mamoor Shahan
Published: October 2021

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of synapse associated protein 1, encoded by SYAP1 when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, SYAP1 expression was correlated with overall survival in basal subtype breast cancer, a molecular subtype sharing significant overlap with triple negative breast cancer. SYAP1 may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of ataxin 7-like 3, encoded by ATXN7L3 when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, ATXN7L3 expression was correlated with recurrence-free survival in basal subtype breast cancer, a molecular subtype sharing significant overlap with triple negative breast cancer. ATXN7L3 may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of vacuolar protein sorting 52, encoded by VPS52 when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, VPS52 expression was correlated with recurrence-free survival in basal subtype breast cancer, a molecular subtype sharing significant overlap with triple negative breast cancer. VPS52 may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.
A Scalable Empathic-Mindset Intervention Reduces Group Disparities in School Suspensions

Published: October 2021

Suspensions remove students from the learning environment at high rates throughout the United States. Policy and theory highlight social groups that face disproportionately high suspension rates—racial-minoritized students, students with a prior suspension, and students with disabilities. We used an active placebo-controlled, longitudinal field-experiment (Nteachers=66, Nstudents=5,822) to test a scalable “empathic-mindset” intervention, a 70-minute online exercise to refocus middle-school teachers on understanding and valuing the perspectives of students and on sustaining positive relationships even when students misbehave. In pre-registered analyses, this exercise reduced suspension rates especially for Black and Hispanic students, cutting the racial disparity over the school year by 45%. Significant reductions were also observed for other groups of concern. Moreover, reductions persisted through the next year when students interacted with new teachers, suggesting that empathic treatment with even one teacher in a critical period can improve students’ trajectories.
Assessing Safety Performance on Urban and Suburban Roadways of Lower Functional Classification: A Comparison of Minor Arterial and Collector Roadway Segments
Authors: Chakraborty Meghna , Gates Timothy
Published: October 2021

Previous research of urban roadway safety performance has generally focused on roadways of high functional classifications, such as principal arterials. However,roadways with lower functional classifications, including minor arterials and collectors, typically possess characteristics that differ from those of higher roadway classes. Therefore, assumptions made on the general effect of the predictor variables from typical safety performance functions may not apply to lower roadway classes. Toaddress these knowledge gaps, a safety performance evaluation of urban/suburban minor arterial and collector roadway segments was performed using traffic androadway data along with eight years of crash data from 189 miles of two-lane urban and suburban roadways in Washtenaw County, Michigan. Mixed-effect negativebinomial models with segment-specific random intercept were developed for minor arterial and collector road segments, considering total, fatal+injury, and propertydamage only crashes. In general, minor arterial roadways showed greater crash occurrence compared to collector roads. Posted speed limit had a significant positiveassociation with crash frequency, and this effect increased when the speed limit exceeded 40 mph. The effect of speed limit was stronger on minor arterial segmentsand for fatal+injury crashes. Additionally, driveway density was found to have a significant effect on safety performance, which was stronger for commercial/industrialdriveways compared to residential driveways and for collector roads compared to minor arterials, particularly when considering residential driveways. On-street parkingwas associated with lower crash occurrence, with a stronger effect on collector roadways, likely due to greater parking turnover when compared to minor arterials.
Efektivitas Penggunaan Visual Art In Counseling Untuk Meningkatkan Konsep Diri Siswa
Authors: kristine gaby
Published: October 2021

Penelitian ini dilatar belakangi hasil pengamatan dan pengalaman peneliti, bahwa siswa sekolah menengah kejuruan tidak mampu berinteraksi dan tidak mendapatkan aktualisasi diri saat di lingkungan sekolah. Siswa mencari aktualisasi diri dengan mengikuti komunitas handcore yang memiliki kebiasaan membuat gravity sebagai ungkapan perasaan yang dituangkan lewat kreatifitas namun tidak terarah sehingga cenderung memiliki konsep diri negatif. Penerapan konseling visual art merupakan salah satu alternatif untuk membantu siswa dalam mengekspresikan hambatan konsep diri. Penelitian ini menggunakan pendekatan kuantitatif dengan teknik penelitian menggunakan pre eksperimen. Rancangan yang digunakan adalah one group pretest-posttest. Sampel diambil secara purposive sampling sebanyak 5 siswa yang skor konsep dirinya negatif. Treatment menggunakan visual art. Visual art in counseling merupakan salah satu teknik konseling seni yang difokuskan pada visualisasi atau simbolisasi untuk mengungkapkan permasalahan konseli melalui berbagai cara seperti mewarnai, menggambar, dan mematung. Teknik ini digunakan untuk membantu konseli dalam mengungkapkan hal-hal yang terkadang sulit terungkap secara verbal, pengalaman-pengalaman atau harapan yang terepresi di alam bawah sadar, dan simbol-simbol subyektif yang ia miliki.

Published: October 2021

Obesity is considered as one of the entrance point of multimorbidity and has an impact on physical and mental health. While some evidence points out to a possible relationship between obesity, multimorbidity and suicidal spectrum, little provide a direct association. Thus, the aim of the present study was to examine the co-occurring effect of both multimorbidity and obesity on suicidal ideation. Methods A cross-sectional analysis of the Canadian Community Health Survey data was conducted. A weighted sample of young adults (18 to 30 years-old) with obesity, from the province of Quebec, of the 2005 (n=394) and 2015–2016 (n=295) cycles were investigated independently. Multimorbidity, suicidal ideation, and health behaviours were self-reported. Results The prevalence of physical multimorbidity was 15% in 2005 and 18% in 2015–2016. Adjusted logistic regressions showed an association between multimorbidity and suicidal ideation (2005: OR 3.59, 95% CI 1.89-6.81; 2015–2016: OR 3.72, 95% CI 1.88-7.36). Among covariates, the significant association of sex (OR 1.98; 95% CI 1.16-3.37) and educational status (OR 3.27; 95% CI 1.49-7.18) in the 2005 cycle, were not replicated in the 2015–2016 cycle (education: OR 0.93; 95% CI 0.46-1.87; sex (OR 0.90; 95% CI 0.48-1.69). Finally, our results suggest no consistent association between health behaviours and suicidal ideation.Conclusion Multimorbidity seems to be associated with suicidal ideation among those with obesity. Attention should be given to multimorbidity management within obesity-related interventions for young people, as the development of suicidal ideation may also be prevented.
