‘Elections can wait!’ The politics of constructing a ‘Hindu atmosphere’ in Kerala, South India
Authors: Paleri Dayal , Santhosh R.
Published: July 2023

The lack of electoral success of the Bharatiya Janata Party (BJP) in the South Indian state of Kerala is often explained through the idea of Kerala ‘exceptionalism’, a broad term used to explain the unique historical, political, and developmental trajectory of the state. However, such explanations do not adequately address the systematic and concerted attempts by Hindu nationalist organizations to transform the cultural sphere of Kerala into a fertile ground for its future electoral politics. Through an ethnographic study of three Hindu nationalist organizations in the civil society sphere of Kodungallur, a multi-religious town in central Kerala, this article explores the politics and implications of their cultural interventions. The article argues that, peeved by an ‘absent Hindu atmosphere’ in Kerala, these organizations are trying to construct new forms of sociality and subjectivity and a grassroots public sphere embedded in Hindu nationalist ideology in Kodungallur. Often described by these organizations as ‘apolitical’ and ‘cultural’, these interventions are indeed a critique of the Kerala public sphere which is characterized by religious pluralism and secular sociality. Hence, the attempt to create a ‘Hindu atmosphere’ by these organizations is a deeply political endeavour aimed at creating an exclusivist Hindu hegemony in the cultural sphere, which they assume will pave the way for their electoral hegemony in Kerala in the long run.
Long-read sequence analysis of MMEJ-mediated CRISPR genome editing reveals complex on-target vector insertions that may escape standard PCR-based quality control
Authors: Higashitani Yuki , Horie Kyoji
Published: July 2023

CRISPR genome editing is a powerful tool for elucidating biological functions. To modify the genome as intended, it is essential to understand the various modes of recombination that can occur. In this study, we report complex vector insertions that were identified during the generation of conditional alleles by CRISPR editing using microhomology-mediated end joining (MMEJ). The targeting vector contained two loxP sequences and flanking 40-bp microhomologies. The genomic regions corresponding to the loxP sequences were cleaved with Cas9 in mouse embryonic stem cells. PCR screening for targeted recombination revealed a high frequency of bands of a larger size than expected. Nanopore sequencing of these bands revealed complex vector insertions mediated not only by MMEJ but also by non-homologous end joining and homologous recombination in at least 17% of the clones. A new band appeared upon improving the PCR conditions, suggesting the presence of unintentionally modified alleles that escape standard PCR screening. This prompted us to characterize the recombination of each allele of the genome-edited clones using heterozygous single nucleotide polymorphisms, leading to confirmation of the presence of homozygous alleles. Our study indicates that careful quality control of genome-edited clones is needed to exclude complex, unintended, on-target vector insertion.

Authors: Pia Magali Perez , Seixas Jakeline Cibelle Santos
Published: July 2023

Small inbound tour operators, around the world, live in a competitive environment. They fight to carve out a profitable business niche. The success of this normally depends on collaboration with other operators and good relations with their local tourism authority. Experience Jordan Adventures (EJA), based in Amman, moved beyond this, reaching out to international organizations for support. In particular, they have taken advantage of their membership of the Adventure Travel and Tourism Association (ATTA) to make contacts and establish relationships with funding bodies such as the United States Agency for International Development (USAID) and the Jordanian Action for the Development of Enterprises (JADE). With their partners’ help, EJA has become a driver and developer of new adventure products, such as the Jordan Trail, a long-distance walking route, and the Jordan Bike Trail. These have brought economic value to remoter communities in Jordan.

Parental smoking in the first two years of a child's life and its associations with breastfeeding
Authors: Blazé Katharine S.R. , Xu Huilan , Buchanan Limin , Baur Louise A. , Wen Li Ming
Published: July 2023

Background

Exclusive breastfeeding for the first 6 months followed by ongoing breastfeeding to 12 months and beyond is associated with multiple benefits for both mother and child. Maternal smoking is associated with a reduction in breastfeeding. Little is known about the effect of partner smoking on breastfeeding.

Aims

This study explores the smoking behaviour of mothers and their partners in the first two years of a child's life and its associations with breastfeeding practice.

Materials and Methods

We performed a secondary data analysis using survey data on 1155 mothers from their third trimester of pregnancy and at six, 12 and 24 months after delivery. Survey questions included smoking status of both mother and partner and breastfeeding intention and practice. Logistic regression models were conducted at each time point.

Findings

Where the mother or both parents smoke, babies were less likely to be breastfed at six months of age (adjusted odds ratio (aOR) 0.29, 95% CI: 0.13–0.66) compared with families where neither parent smoked. Non‐smoking mothers with smoking partners were less likely to intend to breastfeed (aOR 0.29, 95% CI: 0.11–0.82) and their babies were less likely to be breastfed at six and 12 months of age (aOR 0.64, 95% CI: 0.42–0.98 and 0.64, 95% CI: 0.43–0.95 respectively). There was no difference in breastfeeding behaviour between smoking and non‐smoking parents at 24 months.

Conclusion

Smoking parents are less likely to breastfeed their babies at ages six and 12 months. Breastfeeding promotion should target both smoking mothers and smoking partners.
Pharmacokinetic analysis driven letermovir dosing in pediatric hematopoietic cell transplantation patients with resistant CMV disease
Authors: Pai Vinita B. , Tansmore Jessica , Song Eunkyung
Published: July 2023

Background

Reactivation of cytomegalovirus (CMV) in CMV‐seropositive patients after haploidentical T‐cell receptor αβ+/CD19+ depleted hematopoietic cell transplant (HCT) is common. Due to delayed CMV‐specific immune reconstitution, patients may require prolonged antiviral therapy, including secondary prophylaxis (SP). We present our clinical experience with the off‐label use of letermovir for SP in a severely immunocompromised 2‐year‐old toddler with refractory pre‐B‐cell ALL and bilateral retinitis caused by resistant CMV (A594V UL97 mutation) following a haploidentical TCRαβ+/CD19+ depleted HCT.

Methods

The patient underwent measurement of two separate sets of letermovir serum concentrations, drawn at pre‐dose, 1 and 4 h (and 8 h during the second therapeutic drug monitoring) post‐dose. Pharmacokinetic parameters, including AUC0–24 were calculated, and dose adjustment was performed based on the drug level.

Results

While receiving oral letermovir 240 mg once daily without cyclosporine, the observed AUC0–24 was high (75 815 ng h/mL) with a Cmin of 209 ng/mL. The dose was reduced by 25% to 180 mg once daily. Despite the dose reduction, both AUC0–24 and Cmin values further increased to 119 095 ng h/L and 959 ng/mL, respectively. The patient continued oral letermovir 180 mg once daily for about 3 months, with adequate viral suppression (CMV viral load in plasma <150 IU/mL) and no recurrent CMV end‐organ disease or adverse events.

Conclusions

Given limited options for anti‐CMV therapy in young children with resistant CMV, letermovir could be considered as an alternative antiviral for SP. Further studies are warranted to evaluate the pharmacokinetics of letermovir in pediatric allogeneic HCT recipients.

Published: July 2023

In view of the problems such as a plurality of dominant water flow channels formed by flushing the reservoir and inferior development effect in the water injection oilfields, reconstructing the current well pattern and providing well pattern evaluation methods are important ways to enhance oil recovery by improving the injection–production relation and increasing the swept area of water flooding. However, the reservoir engineering methods, the simulation methods, and the artificial intelligence algorithms with few objectives enable comprehensive evaluation of the well pattern. In this article, considering multiple evaluation indexes in oilfield development by the glowworm swarm optimization algorithm and niche technology, automatic well pattern optimization is carried out. The glowworm swarm optimization algorithm has the advantage of efficient global search and simpler algorithm flow, which can speed up the convergence and reduce the parameter adjustment. The niche technology can better maintain the diversity of the solutions and solve the multimodal optimization problems more efficiently, accurately, and reliably. The new method was used to optimize the well pattern of one block in a water-flooding oilfield with high water-cut in a certain oilfield. The optimal well pattern is obtained by multiple iterations to maximize the control degree of the well pattern to the sand body. The results indicate that the injection production correspondence ratio and the reserves control degree of the well pattern to the sand body are improved by 4.48% and 7.94%, respectively.

Temporal logics for hyper properties provide an elegant way to express properties of sets of executions traces. In contrast to classical temporal logics like LTL or CTL, they can express relations of individual execution traces of a system. Among others, they can formalize information-flow principles and other security requirements that are not definable in LTL or CTL. The article by Bernd Finkbeiner provides an overview of temporal logics for hyperproperties. The first part provides an introduction tp HyperLTL and algorithmic problems (satisfiability, model checking, monitoring, synthesis). The second part gives an overview of the landscape of the different variants of hyperlogics and their relative expressiveness.
The molecular phylogeny of the Buccinidae (Caenogastropoda: Neogastropoda) as inferred from the complete mitochondrial 16S rRNA gene sequences of selected representatives
Authors:   Department of Earth and Planetary Sciences, Graduate School of Environmental Studies, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8602, Japan., HAYASHI SEIJI
Published: July 2023

Complete mitochondrial 16S rRNA gene sequences from 35 caenogastropods were obtained to evaluate the phylogenetic relationship of the family Buccinidae at the intra-supra familial level. With respect to intergeneric relationships within the family, the molecular phylogeny supported three clades with statistical significance: Buccinum + Neptunea, Engina + Pisania + Pollia and Penion + Kelletia. These groupings are generally consistent with the morphological and paleontological evidence. In particular, it is noteworthy that the monophyly of Penion and Kelletia was established. Their close relationship as antitropical genera is confirmed for the first time. Babylonia was positioned remotely from the other buccinids confirming recent morphological and molecular work. The monophyly of the current concept of Buccinidae was violated by intercalations of nassariids and fasciolariids.

Published: July 2023

Character development is one of the goals of the teaching and learning process. On the other side, teachers are still looking for an effective way to instill good character in the students through online learning. According to the survey, this research focuses on the students' characters of individual performance, collaborative and spiritual character. The transition from conventional to e-learning because of the Covid-19 pandemic significantly affects the readiness of lecturers and students to get involved in learning activities, which affects the development of the students' characters. This is a mixed method case study, conducted in seven university.  Seven hundred forty-six students of public and private higher educations in Indonesia were investigated in this research. Data collected through observation, field journals and interviews. Data were analyzed through quantitatively and qualitatively. The result showed that the students' performance and collaboration characteristics were not as good as their spiritual character. The students did assignments without paying too much attention to the quality of the content. The students tended to finish the assignments independently, they were rarely involved in the discussion, felt the changing of the academic climate because of the difficulties in accessing the platform to fulfill the needs of remote interaction among the students. The lecturers' readiness was unfamiliar with the teaching platform, and they needed time for converting teaching material into digital form and gave them many assignments.

Authors: Fuchs Jennifer , Zwemer Eric , Gillespie Amanda , Zarick Paul , Berkoff Molly
Published: July 2023

OBJECTIVES

Pediatric patients hospitalized for physical injury and trauma are at increased risk of developing acute stress disorder. Routine identification and referral for treatment of patients with psychological sequelae of traumatic injury were added to the accreditation requirements of the American College of Surgeons for pediatric trauma centers in 2022. We aimed to use quality improvement methodology with iterative interventions to increase psychological screening consults for admitted pediatric trauma patients to 80% in 6 months.

METHODS

We planned a quality improvement intervention to increase identification of posttraumatic psychological symptoms in pediatric trauma patients. We created a Making Trauma Less Traumatic consultation service with a dedicated therapist to provide screening, treatment, and referral. Key interventions included education of key stakeholders and iterative improvements in consultation workflow. Our primary measure was frequency of eligible pediatric trauma patients who had consultation requests for posttrauma therapy during admission. We additionally monitored percent of patients with positive symptom screens and lost to follow-up.

RESULTS

From September 2020 through November 2021, consults for eligible pediatric trauma patients improved from a baseline of 4.1% to a weekly mean of 100%. Of those screened, 32.7% had at least 1 symptom of acute stress. No families declined screening or therapy, though 29.5% were lost to intended follow-up.

CONCLUSIONS

We present a successful model of implementing routine psychological screening of pediatric trauma patients utilizing a dedicated consultation service. A high number of admitted patients screened positive for symptoms during hospitalization. Families were accepting of the intervention though follow-up was challenging.
A Residential Area at the Gates of the City: Controversies Surrounding “Quality of Life”

Published: July 2023

This article looks at the different meanings of the argument for “quality of life” used in support of an urban densification project in Geneva destined for a suburban area located at the gates of the city. It sheds light on the different values that underline this argument and stresses the dangers of using the term “quality of life” in the promotion of inclusive and sustainable cities to justify socially burdensome choices framed by both ecological and rationalist debates without taking into sufficient account the underlying social realities and concerns of the different parties involved. This article analyzes the controversies surrounding an urban densification project, showing how they refer to differentiated visions of “quality of life,” more or less socially and morally legitimized.

Authors: EGE İsmail , ÖZKAN Efekan , POLAT Selahattin
Published: July 2023

Bozburun Peninsula (Marmaris) attracts attention because it contains various karstic shapes on limestones belonging to different periods and it is also an important area in terms of tectonic activity. This study examines the area sizes of the karstic shapes determined by satellite images, topographic maps and field studies, the elevations, slopes, depth value ranges and extensions where they are clustered and the fault lines affecting them have been determined. In order to explain this effect quantitatively, the elongation ratio (RE) and elongation direction (EA α) from morphometric shape indices were used. Poljes, on the other hand, were evaluated in more detail separately from dolines and uvalas, the pitting rates (PR) was calculated. It was understood that in this study which Remote Sensing (RS), Geographic Information System (GIS) technologies and field observations were correlated, folds and fractures that occurred in the Western Taurus Karst Region during the paleotectonic and neotectonic periods had a positive effect on karstification, and it was determined the lie of the karstic shapes to a great extent resemblance to the lie of the faults.

Published: July 2023

In this study, poly(vinyl chloride) (PVC) nanocomposite membranes with maghemite copper oxide nanocomposite (PMC) were developed in order to enhancethe PVC membrane performance and its physicochemical properties for the separation of oil-in-water emulsions. The maghemite copper oxide nanocomposite was synthesized by co-precipitation method. The nanocomposite-based membrane was fabricated by casting the nanocomposite onto a PVC support. By using the co-precipitation process, maghemite copper oxide nanocomposite was created. Various techniques such as Transmission electron microscope (TEM), Scanning electron microscope (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR), have been used to characterize membranes. Water flux, solute rejection, and anti-fouling properties of the membrane were also evaluated. The results demonstrated the nanocomposite's high degree of crystallinity and well-dispersed nanostructure. The resulting membrane was found to have a high oil-water separation efficiency of 98% and an ultra-flux of 0.102L/m2.h compared pure PVC membrane. It was found that the rejection efficiency remained stable over5 cycle times with excellent anti-fouling and cycling stability. The results showed that the maghemite copper oxide nanocomposite-based PVC membrane is a promising material for use in the separation of oil-in-water emulsions, which provide valuable information for the development of new membrane and more flexible, durable, and anti-fouling, making it ideal for use in the separation of oil-in-water emulsions.
Physical Activity and Body Practices developed in Primary Health Care in Brazil from 2013-2021
Authors: Dutra Rinelly Pazinato , Knuth Alan Goularte
Published: July 2023

Background: Physical activity and body practices (PCAF) are important strategies for health promotion, and widely recognized as a form of care within the Brazilian Unified Health System (SUS). The aim of the study was to map records of PCAF developed in Primary Health Care in Brazil, from 2013 to 2021.
Method: This cross-sectional and descriptive study used the Primary Care Health Information System (SISAB) data. Year-by-year PCAF records were presented in absolute and relative values in states, regions, and the country by team type and target audience.
Results: In total, 2,664,288 PCAF actions were recorded nationally throughout the period. A growth of 19,977.5% was observed in records from 2013 to 2019, but they dropped by 75.5% from 2020 and the COVID-19 pandemic. The regions that most recorded PCAF were the Southeast and Northeast, and the states of Minas Gerais, São Paulo, Rio de Janeiro, Bahia, Ceará, Goiás, and Santa Catarina. PCAF actions were directed mainly at the general community, women, older adults, and people with chronic diseases. The Expanded Family Health Center and Family Health were the health teams with the most records.
Conclusions: A significant increase in PCAF records was observed from 2013 to 2019. However, a substantial decrease was identified from 2020, linked to the pandemic. The distribution of actions is still unequal at the state and regional levels, which makes intersectoral strategies necessary to promote public policies and strengthen the PCAF and health promotion in the SUS.

In Africa and Asia, methods for processing grains and vegetables to powder and paste is still dominated by motorized grinding machine, which operates on energized rubbing of two grooved cast-iron discs. This method inadvertently results in tribological degradation of discs into ground foods. And implicitly, metal particles are consumed in ground foods with no detailed understanding of its chemical interaction with human body system and health implications. The aim of this study was to assess corrosion susceptibility of metallic contaminants in ground food and gastro-intestinal environments. Six grinding discs were selected for the study, based on manufacturing methods namely: rotary, cupola and pit furnaces. The discs chemical and phase compositions were determined using x-ray fluorescence spectroscope and x-ray diffractometer respectively. Corrosion susceptibility of metallic contaminants, in deionised water, ground maize water solution and simulated gastro-intestinal solution, were studied using electrochemical potentiodynamic polarisation scan and gasometric methods. Results showed that metallic contaminants corroded steadily in ground maize water but exponentially in simulated gastric solution, therefore suggesting metabolic placation of insinuated health concerns. This study is relevant to food industries where cognitive measures may have to be taken on materials selection to minimise tribological and corrosion degradations of metallic materials into foods.

Good access to the site of oral cancer is essential to adequate three-dimensional resection of the tumor. Lip-splitting approach offers excellent access to all areas of the mouth and pharynx, but this inevitably produces a facial scar. In order to achieve better functional and aesthetic results, we designed a novel incision, which is called Z-shaped incision. 58 patients fulfilled the inclusion criteria were divided into two groups randomly and went through lip-splitting procedure from March 2021 to April 2022. Eventually 22 patients from both groups were reviewed respectively within at least 6 months and evaluated with lip function assessment scale and POSAS. Results showed that Z-shaped incision group performed better than straight incision group on lip contact movement when 7 days and 1 month, and Z-shaped incision group had lower incidence of notched vermillion and recover faster on sensory disorder but Z-shaped incision group didn’t show advantage over straight incision group in other aspects. In conclusion, this study revealed the process of lip function recovery and scar formation during 6 months after lower lip-splitting incision, and introduced a novel Z-shaped lower lip-splitting incision that may be potential alternative in future operation.

Published: July 2023

Objectives. To investigate the long-term outcomes of truncus arteriosus repair, focusing on the impact of associated truncal valve insufficiency and arch obstruction.
Methods. Sixty-five patients underwent surgery at our institution between 1981 and 2021. Twenty patients had truncal valve insufficiency of at least moderate severity and 22 had arch obstruction. Thirty patients underwent primary repair and 35 underwent staged repair. The median follow-up duration was 10.1 years (range, 0–33.5). Perioperative and follow-up data were analyzed retrospectively.
Results. There were six deaths before definitive repair, four of which were associated with extracardiac syndromes. There were seven deaths after definitive repair, with a 10-year overall survival rate of 81%. When patients with extracardiac syndromes other than 22q11 deletion were excluded, the 10-year survival rate improved from 20% in 1981–2000 to 92% in 2001–2021 in patients with moderate or severe truncal valve insufficiency (p = .002) and from 50% to 100% in those with arch obstruction (p = .004). The 10-year survival rate in patients with moderate or severe truncal valve insufficiency and/or arch obstruction was higher after staged repair than after primary repair (88% vs 57%, p = .057). The 10-year freedom from reoperation rate other than for the right ventricular outflow tract was 63%.
Conclusions. Truncus arteriosus can now be treated with a low mortality risk. The presence of truncal valve insufficiency or arch obstruction was associated with increased mortality in the early years but the mortality rate improved in later years.
Institutional Review Board Approval: The study was approved by our institutional review board (25 November 2022; reference number 2022-110).

Оптические свойства ван-дер-ваальсовых гетероструктур на основе 2D-монослоев борофена, нитрида галлия и оксида цинка

Published: July 2023

In this paper, we consider two new atomic models of van der Waals vertical heterostructures of metal-semiconductor type based on a 2D buckled triangular borophene with metallic conductivity and graphene-like 2D monolayers of gallium nitride GaN and zinc oxide ZnO, which are semiconductors. Using the density functional theory, the equilibrium configurations of supercells of the borophene/GaN and borophene/ZnO heterostructures are found and their thermodynamic stability at room temperature is shown. Within the framework of the nonstationary first-order perturbation theory, the optical characteristics (complex permittivity and absorption coefficient) are calculated in the electromagnetic radiation wavelength range of 0.2–2 μm. The presence of anisotropy in the optical properties of the borophene/GaN and borophene/ZnO heterostructures is established when the direction of light polarization is chosen. This is due to different manifestations of the optical properties of the constituent monolayers of the heterostructure. When light is polarized in the direction of the zigzag edge of the GaN/ZnO (along the X axis), the optical properties of GaN and ZnO semiconductor monolayers are predominantly manifested. When light is polarized in the direction of the zigzag edge of the borophene monolayer (along the Y axis), the optical properties of borophene manifest themselves. A synergistic effect has been found from the combination of borophene and ZnO monolayers in the composition of the borophene/ZnO vertical heterostructure, which manifests itself in the form of a section of the increasing plot of the real and imaginary parts of the complex permittivity in the infrared region for both directions of light polarization. It is shown that the difference in the values of the absorption coefficient of the borophene/GaN heterostructure between the UV and visible ranges can reach ~ 7 times, between the UV and near IR ranges - ~ 14 times, and for the borophene/ZnO heterostructure this difference can be up to ~ 6 times and up to ~18 times, respectively. It is predicted that borophene/GaN and borophene/ZnO heterostructures can be used to create UV radiation detectors.
Brothels as Heterotopic Spaces: An Analysis of the Movie Begum Jaan
Authors: Kurien Swetha Mary
Published: July 2023

Brothels are restricted spaces for individuals who follow and praise the societal norms of morality. But these spaces also give easy access to the patriarchal society to suppress women since they do not fit into the so-called “respective” roles in society. Brothels are usually viewed as spaces for men to fulfill their desire for sex, enhancing their masculinistic peculiarities. Women are always suppressed in these sexual acts as they are viewed as derogatory subjects and forced to subjugate under men. The Bollywood movies have created a series of narrations portraying brothels where the above peculiar characteristics are reinitiated and represented. Contrary to this, the movie Begum Jaan portrays a brothel negating all the stereotypical understandings of it, as argued in the paper. To prove this, the paper views the Brothel in the movie as a “heterotopia,” keeping in mind the concepts related to gender, power, and space itself through qualitative analysis.
Training Image Synthesis for Shelf Item Detection reflecting Alignments of Items in Real Image Dataset

We propose a novel cut-and-paste approach to synthesize a training dataset for shelf item detection, reflecting the alignments of items in the real image dataset. The conventional cut-and-paste approach synthesizes large numbers of training images by pasting foregrounds on background images and is effective for training object detection. However, the previous method pastes foregrounds on random positions of the background, so the alignment of items on shelves is not reflected, and unrealistic images are generated. Generating realistic images that reflect actual positional relationships between items is necessary for efficient learning of item detection. The proposed method determines the pasting positions for the foreground images by referring to the alignment of the items in the real image dataset, so it can generate more realistic images that reflect the alignment of the real-world items. Since our method can synthesize more realistic images, the trained models can perform better.

Ray tracing remains of interest to Computer Graphics community with its elegant framing of how light interacts with objects, being able to easily support multiple light sources, and simple framework of merging synthetic and real cameras. Recent trends to provide implementations at the chip-level means raytracing’s constant quest of realism would propel its usage in real-time applications. AR/VR, Animations, 3DGames Industry, 3D-large scale simulations, and future social computing platforms are just a few examples of possible major impact. Raytracing is also appealing to HCI community because raytracing extends well along the 3D-space and time, seamlessly blending both synthetic and real cameras at multiple scales to support storytelling. This presentation will include a few milestones from my work such as the Slicing Extent technique and Directed Safe Zones. Our recent applications of applying machine learning techniques creating novel synthetic views, which could also provide a future doorway to handle dynamic scenes with more compute power as needed, will also be presented. It is once again renaissance for ray tracing which for last 50+ years has remained the most elegant technique for modeling light phenomena in virtual worlds at whatever scale compute power could support.

Background: Family communication can become a support system for adolescents. Ineï¬€ective communication in the family causes emotional problems and poor psychological well-being in adolescents.
Purpose: This study aimed to analyze the determinant factor of eï¬€ective family communication in adolescents.
Methods: This was a cross-sectional multi-centre design with 357 participants aged 15-16 from fve high schools in Indonesia. We used the convenience sampling method to select participants. Communication in the family questionnaire, Rosenberg Self Esteem Instrument, Depression Anxiety Stress Scale (DASS-21), and the Scale for Suicide Ideation (SSI) questionnaires were used to measure communication within the family, selfesteem, stress, anxiety, depression, and suicide ideation, respectively. Data were analyzed using Chi-square and binary logistics regression.
Results: Most of the adolescents were male (52.1%), had harmonious families (96.6%), had economic status above the minimum wage (65.5%), had high self-esteem (88.5%), and had high social support (67.8%). However, in terms of mental health problems, as many as 47.3%, 74.2%, 72%, and 30.5% of adolescents experienced stress, anxiety, depression, and suicidal ideation, respectively. The multivariate analysis concluded that gender (AOR: 0.499; 95% CI: 0.294-0.847) and socioeconomic status (AOR: 0.2.162; 95% CI: 1.296â€“3.608) were signifcantly correlated with family communication.
Conclusion: Males adolescents are more likely to have ineï¬€ective family communication than female adolescents. Also, adolescents with a family socioeconomic status below the minimum wage have a greater risk of ineï¬€ective family communication. Therefore, it is essential to improve family communication through assertive communication training in adolescents and families in the educational and community setting.

Objective: To determine the sociodemographic and clinical characteristics associated with positive attitudes towards sexuality in older adults seen in the outpatient clinic of the Hipólito Unanue National Hospital from september to december, 2021. Methods: Cross-sectional analytical observational study, which included 227 adult patients over 60 years of age from the outpatient clinic of the HNHU geriatrics service attended by teleconsultation. Attitudes towards sexuality were measured by applying the Questionnaire of Attitudes towards Sexuality in Older Adults, dividing the result into positive and negative attitudes.Results: 86.3% of older adults have a positive attitude towards sexuality, the age of 60 to 79 years was presented in 73% of these patients, higher education was higher in the group with positive attitude (47%), 53.6% of the patients with a positive attitude reported having a current partner, having received educational talks increases the probability of a positive attitude towards sexuality by 3.12 times. In the bivariate analysis, there was a statistically significant association between age 60 to 79 years (RP: 1.31, 95%CI: 1.12-1.52, p<0.001), higher education (RP: 1.19, 95%CI: 1.08-1.31, p=0.001), having a current partner (RP: 1.32, 95%CI: 1.19-1.46, p<0.001), having received educational talks (RP: 1.13, 95%CI: 1.03-1.24, p=0.033). In the multivariate analysis, an association was found between having a current partner and a positive attitude towards sexuality (RPa: 1.177, 95%CI: 1.09-1.26, p<0.001).Conclusions: There is a high frequency of positive attitude towards sexuality in older adults, and having a current partner was an independent associated factor.
