Authors:   Politeknik Negeri Bandung, Kania Rafiati , Ramadhani Nabila Shafira , Wibisono Nono , Gunawan Arie Indra
Published: March 2024

Subscriber-based Video on Demand (SVoD) is currently growing business sector during the COVID-19 pandemic. Since the pandemic effect human mobilization, the Indonesian government strictly regulated visiting the cinema to press Covid-19 outbreak. Consequently, film providers and consumers adopt SVoD as an alternative digital platform. Nevertheless, Indonesian subscriptions are currently lagging behind other countries. In addition, a survey from Coalition Against Piracy in 2019 has discovered that 63 % of Indonesian consumers opt to access illegal streaming services instead of paying subscription fees to video streaming providers. This research empirically examines social influence, perceived risk, hedonic motivation, and utility value to influence behavioral intention to understand what factors influence paying subscriptions. The hypotheses proposed in our research model are tested on a sample of 291 Indonesian subscribers of SVoD platforms. The partial-least square modeling result shows that social influence, hedonic motivation, and utilitarian value can, directly and indirectly, influence behavioral intention. Contrary to research hypotheses, the perceived risk of adopting illegal streaming videos can only indirectly influence behavioral intention. Finally, it is noted that a combination of external and internal consumer motivation will impact subscriptions intention.
Exploring Voice of Customers to Chatbot for Customer Service with Sentiment Analysis
Authors:   School of Business and Management, Institut Teknologi Bandung, Indonesia, Murwati Anggun Siwi , Aldianto Leo
Published: March 2024

Abstract. Chatbots have been widely employed across a wide variety of companies and industries, from small- and medium-sized businesses to large corporations, and from e-commerce to financial institutions. Although chatbots have proven to be far more efficient and quicker than human agents, they do not always provide customers with a satisfactory experience because they lack a personal touch. Customer issues are often left unresolved and many are unsatisfied with chatbot services. This is unfavorable for firms that use chatbots for customer services as this jeopardizes their relationship with valued consumers. Thus, customer input is essential to streamline the product innovation process. This study uses a hybrid method involving lexicon-based TextBlob and logistic regression techniques to identify the sentiments of consumers toward chatbots for customer services based on user-generated content on Twitter. The results show that although people generally have positive encounters with chatbots, the gap between positive and negative sentiments is relatively small. This research provides insights that businesses can use to improve chatbot technology based on the voice of the customer to provide users with higher quality customer services in the future, especially since unsatisfied customers could be a threat to a business’s performance. Keywords: chatbot, customer services, sentiment analysis, social media mining, voice of customers.

Published: March 2024

Abstract. Bandung, the capital of West Java, is 2021 Indonesia's most crowded city. Congestion happens even then since the number of cars in Bandung has grown by an average of 11% annually. To overcome the congestion, the Ministry of Transportation Republic Indonesia programme created the "Teman Bus" programme in December 2021. Therefore, this study explores the impact of factors influencing passenger loyalty towards public bus services. A cross-sectional survey of bus users in Bandung was conducted in June 2022, with 211 respondents. The data were analysed using structural equation modelling. Using PLS-SEM, the relationship between constructs and loyalty was examined, and importance-performance map analysis was used to determine which drivers should prioritise increasing levels of a target construct of interest. The results indicate that perceived safety and security, perceived service quality, and image significantly influence loyalty. It also implies that those three variables, as revealed by the study's findings of the importance and performance matrix, need to be improved to increase customer loyalty when it comes to bus services.

Factors associated with young children being overweight on entry to primary school
Authors: Hall Joanne , Wee Christine , Harries Anthony D
Published: March 2024

Childhood obesity is a serious public health challenge, and there is limited evidence to show which pre-school interventions may prevent its occurrence. This study assessed whether selected factors, including contact with the Starting Well 0–19 service for children aged 1–3 years in north-west England, influenced children's risk of being overweight at primary school entry. It found that families with the most contact with the service (an integrated health visitor and children's centre offer) were more at risk. The findings show that the focus of these contacts does not positively influence risk factors for later overweight prevalence. The study findings replicate a known association between deprivation and children being overweight. Families having the highest contact levels with the Starting Well service had a significant association with their children being overweight at entry to primary school. This provides an opportunity to target these families with healthy lifestyle interventions and reduce the potential risk of childhood obesity.

Subject matter knowledge in Primary Education teacher training
Authors: Moral Santaella Cristina , De la Herrán Gascón Agustín
Published: March 2024

INTRODUCTION. The article questions a basic problem of didactics: the relevance of subject matter knowledge as a quality requirement in teacher training. Subject matter knowledge is assumed to be necessary to facilitate student learning and education. Specifically, it is understood as a requirement for teachers to be able to carry out didactic designs and developments that facilitate meaningful learning experiences and strengthen the conceptual structure of students. The objective of the research is to know if future Primary Education teachers and preservice Primary Education teachers have an adequate knowledge of subject matter knowledge. METHOD. To answer the objective, the type and organization of their knowledge is examined through concept maps, evaluating the productions with validated structural and semantic rubrics. RESULTS. The results show that, in general, teachers have a very poor organization of subject matter knowledge, with a weak didactic potential. DISCUSSION. Likewise, the data indicate that there are insignificant differences between the concept maps of teachers in training and those made by practicing teachers, which reflects a similar andcyclical knowledge structure. The conclusions point to the low and limited impact of teacher education programs on pre-service teachers’ acquisition of subject matter knowledge, even though it is understood as a general didactic requirement for teacher education and, for the development of quality teaching.

Introduction: Prosthetic joint infections (PJIs) are a dreaded complication of joint arthroplasty. Zoonotic organisms such as Pasteurella multocida (PM) rarely cause PJIs. Still, these organisms can be challenging to treat due to a low suspicion index and inadequate growth on culture. Next-generation sequencing (NGS) can be used to identify organisms in culture-negative PJIs. This is the first reported case of a PM positive total hip arthroplasty PJI using NGS. Case Report: We report the case of a 70-year-old male presenting with a periprosthetic hip infection. PM was identified in high relative abundance on NGS and grew in culture. Subsequent intraoperative samples were culture negative for Pasteurella, but NGS demonstrated continued presence of Pasteurella. Conclusion: PM is a rare case of PJI, but a high index of suspicion must be maintained in the appropriate clinical context. NGS is a vital tool for the identification of culture-negative organisms like PM. Keywords: Prosthetic joint infection, next-generation sequencing×culture negative, Pasteurella multocida, next-generation sequencing, hip infection, arthroplasty.

Introduction: Extensor tendon subluxation or dislocation resulting from sagittal band rupture can be associated with snapping, catching, locking, pain, and swelling of the finger. Several etiologies were reported in the literature, with frequent mention of a traumatic rupture caused by a direct blow at the level of the metacarpophalangeal joint (MCPJ). The other causes of sagittal band injuries are degenerative disease, congenital infection, and rheumatoid arthritis. To our knowledge, we report the first case of spontaneous idiopathic bilateral sagittal band rupture. Case Report: We, herein, present the case of a seronegative 29-year-old female who presented with pain and swelling in the dominant hand for 4 days. Conclusion: Upon examination, she was found to have bilateral dislocation of the extensor tendons at the level of the (MCPJ) of the third and fourth digits. Any underlying cause was excluded, and the diagnosis was confirmed with a dynamic ultrasound study. Keywords: Sagittal band, extensor tendon dislocation, spontaneous sagittal band rupture, metacarpophalangeal joint, hand pain.

Published: March 2024

Background: Severe burns can significantly impact various organ systems, including the gastrointestinal (GI) system. GI complications are frequently observed in patients with over 20% total body surface area (TBSA) burn. Objectives: This case series delves into the intricate phenomenology of post-burn GI dysfunction, challenging conventional cause-and-effect paradigms. Our aim is to discern, comprehend, and explore variables influencing positive and negative outcomes, laying the foundation for further research given the current heterogeneity in the literature. Methods: Severe burn patients with GI dysfunction identified between April 1, 2022, and July 31, 2022, from the institutional database are included in this retrospective case-series, and comparisons were made across baseline and treatment conditions across participants. Data were collected on demographics, burn characteristics, complications, and treatment outcomes. Results: We analysed 12 patients with severe burns and GI dysfunction and categorized them into two patterns: Pattern A, characterised by early onset symptoms, gastric and small bowel dilatation, and a relatively benign course with high recovery rates was observed in 6 patients; and Pattern B, characterised by late-onset symptoms, colonic dilatation, shock, and a high mortality rate due to megacolon was seen in 6 patients. Conclusion: The post-burn GI dysfunction observed in our study is a complex interplay of multiple factors. Adequate fluid resuscitation, timely excision of necrotic tissue, staged food ingestion, specific nutrient administration, and appropriate use of antibiotics and judicious use of selective digestive decontamination (SDD) are essential strategies to prevent and treat this syndrome.

Membrane-based optical fiber Bragg grating pressure sensor for health monitoring of pile foundations
Authors: Wu Wenjing , Sun Bin , Chen Shengyu , Gong Weiming , Wei Heming
Published: March 2024

A fiber Bragg grating (FBG) pressure sensor is proposed, designed, and fabricated for lateral earth pressure sensing, in which the FBG sensor is mounted on a 3D printed trestle structure combined with a membrane. The applied pressure can cause a deformation on the membrane, and then this deformation applied on the trestle structure causes tensile strain on the FBG. The proposed sensor is functionalized as a high-sensitive pressure transducer capable of converting the pressure into strain on the FBG. Here, the performance of the proposed sensor is numerically and experimentally investigated. The results show that the pressure sensitivity at 30°C is 10.62 pm/kPa within a range of 0–0.6 MPa. Due to the thermal expansion of the structure, the pressure sensitivity coefficient decreases with the increase of temperature; however, the cross effect between the temperature and strain on the sensing sensitivity is investigated and can be eliminated. The fabricated sensor has advantages of high sensitivity, good stability, and high pressure resolution, so it has potential in the field of structural health monitoring.
Object phase-valid region segmentation method for FPP-based three-dimensional measurement
Authors: Zou Yang , Li Qingwu , Yu Dabing , Gao Zheng , Chen Suyang
Published: March 2024

In most existing studies based on fringe projector profilometry (FPP), the whole scenario is reconstructed, or the ideal experimental settings are established to segment the object easily. However, in real industrial scenarios, automated object detection and segmentation are essential to perform object-level measurement. To address the problem, a dual-wavelet feature interaction network (DWFI-Net) is developed in this paper to perform object phase-valid region segmentation, where both the background and shadow are removed. In our work, the modulation and wrapped phase maps are considered as inputs innovatively. The modulation maps provide abundant structures and textures, while the wrapped phase maps complement and enhance shadows and edges. An adaptive wavelet feature interaction (AWFI) module is presented to learn and fuse the features, where discrete wavelet transformation (DWT) is applied to decompose the features. An edge-aware discrete cosine transformation (EDCT) module is developed as a decoder, where the discrete cosine transformation (DCT) is applied to interpret the fused features. Qualitative and quantitative experiments are performed to verify the superiority of our DWFI-Net and its effectiveness on object-level three-dimensional measurement based on FPP.
Optical properties of chain-like atmospheric aerosol particles
Authors: Liu Hanyan , Li Xingcai , Wang Juan , Cheng Ning
Published: March 2024

Using the generalized multiparticle Mie-solution method, this study examines the optical properties of chain-like particles under different atmospheric conditions and various arrangements. The structural composition of aerosols exhibits a more pronounced impact on their extinction and absorption cross sections when the incident wavelength is below 600 nm, whereas significant changes are observed in backscattering cross sections for incident wavelengths above 600 nm. As the orientation angle between the incident wave and particle chain increases, the extinction cross sections and absorption cross sections exhibit varying degrees of decline. Furthermore, marine atmospheric aerosol chains demonstrate similar extinction cross sections to those of polluted atmospheric aerosols, and their absorption cross sections closely resemble those of clean atmospheric aerosols. In addition, for a particle chain of fixed length, the greater the disparity in particle sizes within the chain, the larger the difference between the backscattering cross section and that of the chains with equal particle sizes. This research provides theoretical support for assessing the climate effects of aerosols and inverting aerosol properties by LiDAR data.

Published: March 2024

The imaging
quality of a rotational
reflection high-speed tracking system is greatly affected by the
optical characteristics of the reflector and the depth of field
limitations of the imaging system, especially for tracking systems
working in small distances. In order to improve the imaging quality,
this paper focused on two factors that affect the imaging quality:
double vision caused by the optical characteristics of reflectors and
blurring caused by the depth of field of imaging systems. This paper
quantified the impact of these two factors on imaging through
theoretical analysis, proposed a method of changing the hardware
position, and conducted a simulation and experiments. The results show
that the proposed solution in this paper can effectively improve the
imaging quality of the system. The content studied in
this paper has certain significance in the field of high-speed
tracking of rotating reflectors and can provide reference for relevant
researchers.
Photodetector with a metalens packaging module for visible light communication based on RGBY illumination LED light source
Authors: Xi JianFei , Liu Jay GuoXu , Tu Yan , Yang Lanlan , Qin Tao
Published: March 2024

A novel, to the best of our knowledge, photodetector with a metalens packaging module used as the visible light communication (VLC) receiver is proposed and designed. An LED consisting of red, green, blue, and yellow chips (RGBY-LED) is adopted as the transmitter for intensity modulation direct detection VLC systems. A metalens array with a numerical aperture (NA) of 0.707 used as a polarization-insensitive planar lens of the VLC system receiver is designed at wavelengths of 457, 523, 592, and 623 nm corresponding to blue, green, yellow, and red for high efficiency. Compared with a traditional Fresnel lens positive-intrinsic-negative (PIN) photodetector module as the VLC receiver, the introduction of a metalens module can decrease the form factor of the VLC receiver module and, in particular, it is much thinner. The combination of the multi-color LED transmitter and photodetector metalens packaging module receiver can increase the modulation bandwidth due to four different wavelengths used for the VLC system. Finite-difference time domain (FDTD) simulations are performed to validate the performance of the photodetector with a metalens module. It is revealed that the corresponding efficiencies of 57.5%, 55.4%, 57%, and 56.3% were achieved at wavelengths of 623, 592, 523, and 457 nm, respectively, based on a metalens array with a 0.707 NA and 2.5 µm radius of the active area of the photodetector. It is a promising technology for indoor VLC systems such as those for smart phones and other Internet of Things devices due to the need for compact packaging for the receiver.
Climate change, biodiversity loss, and Indigenous Peoples’ health and wellbeing: A systematic umbrella review

Published: March 2024

Indigenous Peoples worldwide are experiencing a cascade of impacts on their health and wellbeing as a result of climate change and biodiversity loss. Existing literature at the interface of climate change, biodiversity loss, and Indigenous health tells us that Indigenous Peoples are among those most disproportionately and acutely affected by these impacts. Yet, a gap exists with respect to comprehensively and critically synthesizing the impacts reported across this literature and identifying Indigenous-led responses. Guided by an Indigenous advisory group, we employed a systematic umbrella review methodology, following PRISMA guidelines, to characterize the global secondary literature (PROSPERO registration #: CRD42023417060). In so doing, we identified the proximal, intermediate, distal, and gendered impacts of climate change and biodiversity loss on Indigenous health and wellbeing as well as Indigenous-led responses. Five databases were searched for published reviews, along with a grey literature search that focused on underrepresented geographic regions in the academic literature. Two independent reviewers conducted two-stage screening, data extraction, and quality assessment of retrieved records. Basic descriptive statistics were calculated. Qualitative data were analyzed thematically, using a constant comparative approach. A total of 38 review articles met the eligibility criteria and 37 grey literature records were retrieved and included in the review. Reviews were published between 2010–2023 and geographically clustered in the Circumpolar North. Intersecting proximal, intermediate, and distal impacts were characterized as place-based and specific, and linked to colonialism as an antecedent to and driver of these impacts. Gendered impacts were underexplored within reviews. Reviewed literature underscored the value of engaging diverse knowledge systems; platforming localized, community-led adaptation to climate change and biodiversity loss, while addressing sociopolitical constraints to these efforts; and applying a broader conceptualization of health that aligns with Indigenous frameworks. Going forward, we must foreground equity- and rights-based considerations within integrated responses to climate and biodiversity crises.
The influence of obesity and fat distribution on ankle muscle coactivation during gait
Authors: Maktouf Wael , Ferhi Hamza , Boyas Sébastien , Beaune Bruno , Gaied Chortane Sabri , Portero Pierre , Durand Sylvain
Published: March 2024

Background

Excessive body weight is associated with gait alterations. In none of previous studies, body fat distribution has been considered as a factor that could change gait parameters and induce different neuromuscular adaptations.

Objective

This multicenter, analytical, and cross-sectional study aimed to investigate the influence of the body mass distribution on gait parameters and ankle muscle coactivation in obese individuals.

Methods

Three distinct groups were included in the study: a non-obese control group (CG, n = 15, average age = 32.8 ± 6.5 years, BMI = 21.4 ± 2.2 kg/m2), an obese-android group characterized by a Waist to Hip Ratio (WHR) greater than 1 (OAG, n = 15, age = 32.4 ± 3.9 years, BMI = 41.4 ± 3.9 kg/m2, WHR = 1.2 ± 0.2), and an obese-gynoid group with a WHR less than 1 (OGG, n = 15, age = 35.4 ± 4.1 years, BMI = 40.0 ± 5.7 kg/m2, WHR = 0.82 ± 0.3). All participants walked on an instrumented gait analysis treadmill at their self-selected walking speed for one minute. Spatiotemporal parameters, walking cycle phases, vertical ground reaction force (GRFv) and center of pressure (CoP) velocity were sampled from the treadmill software. Electromyography (EMG) activity of the gastrocnemius medialis (GM), the soleus (SOL) and tibialis anterior (TA) were collected during walking and used to calculate coactivation indexes (CI) between ankle plantar and dorsal flexors (GM/TA and SOL/TA) for the different walking cycle phases.

Results

Compared to OAG, OGG walked with shorter and larger strides, lower CoP velocity and GRFv. During the single support phase, SOL/TA coactivation was higher in OAG compared to OGG (p < .05). During the propulsion phase, SOL/TA coactivation was higher in OGG compared to OAG (p < .05).

Conclusion

Gait parameters and ankle muscle coactivation in obese individuals seem to be strongly dependent on body mass distribution. From the biomechanical point of view, body mass distribution changes gait strategies in obese individuals inducing different neuromuscular adaptations during the single support and propulsion phases.
Surveillance of the recurrence time of the effectiveness of national and region-level quarantines of COVID-19 pandemic in Chile

Published: March 2024

The World Health Organization has recommended a range of social and health measures to mitigate the spread of coronavirus disease 2019 (COVID-19), including strategies such as quarantines, border closures, social distancing, and mask usage, among others. Specifically, the Chilean authorities implemented the “step-by-step” plan, built on the concept of dynamic quarantine. Numerous studies have examined the effectiveness of these quarantines in Chile during the pandemic, utilizing data published by the Chilean Ministry of Health. This study’s primary aim was to enhance our understanding of quarantine effectiveness in Chile during the pandemic. We accomplished this by analyzing the distributional behavior of the time until the COVID-19 pandemic was deemed under control or not. In our study, we defined an event with two potential outcomes related to the instantaneous reproductive number (Rt), which signifies the time until a change in the event outcome occurs. Importantly, we did not predefine a specific temporal observation unit. These findings allowed us to complement the concept of effective quarantine by considering the dynamics generated by the protocols, such as phase 1 of the quarantine, in achieving natural herd immunity in response to the number of COVID-19 cases and Rt. We assessed the behavior of the mean and median residual lifetime until the initiation of controlled/uncontrolled episodes of the COVID-19 pandemic based on Rt in all regions of Chile. Despite variations in the distribution of residual times for controlled/uncontrolled episodes in different regions, there was a similar observation during the period considered (between March 2020 and March 2021): the mitigation measures did not produce a clear positive effect for controlling the epidemic. The residual times of episodes with Rr,t > 1 were not different from those episodes with Rr,t ≤ 1.

Published: March 2024

Despite growing evidence supporting the importance of the quality of attachment during adolescence, no studies have been conducted to date in the Arab world due to an absence of valid and reliable tools to measure this construct in Arabic. The Inventory of Parent and Peer Attachment–Revised (IPPA-R) was devised as a self-report questionnaire in English to assess the quality of adolescent attachment to mother, father, and peers, each scale consisting of 25 items. The current study sets out to determine the psychometric properties of the Arabic IPPA-R and to explore attachment styles in Lebanon in a sample of 765 Lebanese adolescents. Results suggested a modified three-factor structure to reach satisfactory reliability of the Arabic IPPA-R, resulting in a modified questionnaire consisting of 19 items for each of mother (α = .82) and father (α = .85), and 21 items for peers (α = .89). Strict measurement invariance across gender was achieved for the IPPA-R parental forms, while only scalar invariance was achieved for the IPPA-R peers form. Overall, there were significant differences in attachment scores to mother and father, with adolescents scoring higher on attachment to mother, with both scores being significantly lower than attachment to peers. Gender differences were found on the peer scale with girls scoring significantly higher than boys. Results are interpreted from a cultural lens, emphasizing the importance of accounting for cultural, religious, and socio-economic factors in understanding adolescent attachment. This study is the first conducted in the Arab region and provides a road map to understanding gender-roles, parental expectations and adolescent perceived parenting, and their impact on adolescent attachment scores.
Relationship between gender roles, motherhood beliefs and mental health

Published: March 2024

Gender roles, as social constructs, play a significant role in shaping individuals’ beliefs and attitudes, influencing various aspects of life, including perceptions and expectations surrounding motherhood. These beliefs, acquired through culture and society, can have an impact on our mental well-being. This research consists of three independent studies conducted in the Mexican population. In the first and second studies, we extended the Attitudes Towards Gender Roles Scale and Motherhood Beliefs Scale and performed psychometric validation through exploratory and confirmatory factor analysis. The aim of including additional items in both scales was to update these attitudes and beliefs in Mexican culture to avoid the traditionalist bias in both instruments. Finally, the third study examined the relationship between the new versions of both scales and symptoms of depression, anxiety, and Positive Psychological Functioning as indicators of mental health in women and men with and without children. Our findings revealed a significant association between higher levels of traditional attitudes towards gender roles and traditional motherhood beliefs, as well as between non-traditional attitudes towards gender roles and non-traditional beliefs about motherhood. Interestingly, we observed that traditional attitudes toward gender roles were associated with lower anxiety and depression scores, while non-traditional attitudes were associated with higher levels of depression. Furthermore, individuals who embraced non-traditional attitudes towards both gender roles and motherhood beliefs tended to exhibit better psychological well-being in all subsamples. Additionally, women generally showed lesser alignment with traditional attitudes towards both gender roles and motherhood beliefs compared to men. However, women reported higher rates of depression and anxiety, along with lower psychological well-being scores, than their male counterparts. This highlights the significant influence that traditional cultural norms about gender roles and motherhood have on women’s mental health, underscoring the need for a deeper understanding and reevaluation of these traditional constructs in society.

Published: March 2024

This study aimed to explore the needs and wants of older adults in the context of movement-assistive clothing (MSC), with a focus on muscle strength and posture correction. A survey was conducted to understand the needs and wants of older adults, considering aspects of functions and designs, and to evaluate the comfort, safety, ease of use, usefulness, and intention of users to purchase and use products. A total of 408 individuals aged > 65 years participated in the study. The data were analyzed using descriptive analyses, such as mean, standard deviation, percentages, Cronbach’s alpha, chi-square test, independent t-test, analysis of variance, and regression using IBM SPSS 27.0. Exploratory Factor Analysis was also conducted to test the hypotheses. Open-ended questions were extracted using major themes after color-coding. Based on the results, design recommendations were derived, including the development of pants and innerwear with casual, minimalist styles, featuring achromatic colors, and utilizing stretchy, breathable fabrics. Comfort, safety, ease of use, and usefulness emerged as critical factors influencing the purchase and use of MSC by older adults. This study aimed to establish design guidelines by understanding the needs and wants of older adults and considering the aspects of movement-assistive clothing to relieve musculoskeletal issues. Accordingly, these findings are expected to aid in the creation of wearable suits using flexible fabric artificial muscles for active musculoskeletal correction in older adults.
The “bubbles”-study: Validation of ultra-short scales for the assessment of depression, anxiety and stress symptoms
Authors: Brailovskaia Julia , Schneider Silvia , Margraf Jürgen
Published: March 2024

Depression, anxiety and stress symptoms cause substantial psychological and economic burdens around the globe. To mitigate the negative consequences, the negative symptoms should be identified at an early stage. Therefore, the implementation of very brief valid screening tools in mental health prevention programs and in therapeutic settings is advantageous. In two studies on representative German population samples, we developed and validated three ultra-short scales–the “bubbles”–that consist of only one item based on the Depression Anxiety Stress 21 subscales (DASS-21) for the assessment of depression, anxiety and stress symptoms. The results of Study 1 (N = 1,001) and Study 2 (N = 894) revealed that the bubbles are valid instruments that fit the DASS-21 subscales on the factor level. Moreover, the bubbles replicated the association pattern of the DASS-21 subscales with demographic variables, and with variables that belong to the negative and the positive dimension of mental health. Thus, due to their time- and cost-efficiency, the bubbles can be used as brief screening tools in research (e.g., large-scale studies, longitudinal studies, experience sampling paradigms) and in praxis. Their shortness can prevent fatigue, motivation decrease, and participants’ drop-out.

As unidades de conservação (UCs), notadamente os Parques Naturais, vêm se transformando no palco preferencial para a prática do ecoturismo no Brasil, tendo recebido, somente no ano de 2019, um fluxo superior a 15 milhões de visitantes (ICMBio, 2020). Por esse motivo, essa modalidade de turismo que, em sua definição, busca promover a conservação dos recursos naturais, necessita ser planejada, visando à minimização dos eventuais impactos que possa provocar. O presente trabalho teve o objetivo de avaliar os impactos causados pela visitação na trilha de um dos mais conhecidos atrativos da Chapada Diamantina, a Cachoeira do Buracão, localizada no Parque Natural Municipal do Espalhado, no município de Ibicoara (Bahia). Para isso, utilizou-se a metodologia Visitors Impact Management (VIM) através de uma adaptação ao Manual de Monitoramento e Gestão dos Impactos da Visitação em Unidades de Conservação, elaborado pela Secretaria de Meio Ambiente do Estado de São Paulo e pelo WWF-Brasil. Como resultados, identificou-se que os danos à vegetação são o principal impacto, decorrentes de uma falta de planejamento do traçado da trilha, tendo sido sugeridas medidas corretivas que ajudem a saná-los.

Inductively coupled argon plasma mass spectrometry (ICP-MS) was used to study the elemental composition of the underground and aboveground parts of the Datura stramonium growing on the territory of the Republic of Uzbekistan. The obtained data show that 41 elements were found in the composition of the vegetative organs of the D. stramonium, including 6 macroelements (Ca, P, K, Na, S, Mg), 8 essential microelements (Co, Cr, Cu, Fe, Mn, Se, Zn, Mo), and 6 conditionally essential. Moreover, 6 trace elements (B, Si, Ni, V, As, Li), 16 toxic (Pb, Cd, Ge, Sr, Zr, Tl, Bi, Sn, Sb, W, Ag, Ba, Al, Ga, Ti, Be) and 5 little studied elements (Nb, Cs, Ta, Rb, Re) were identified. It was revealed that among the detected elements in D. stramonium, 3 macroelements (Ca, K and Fe) are contained in a concentration of more than 1000 mg/kg, 4 elements (P, S, Mg, Si) are from 100 to 1000 mg/kg, 3 elements (Na, Mn, B), ranging from 10 to 100 mg/kg and the rest were in the range of less than 10 mg/kg. The macroelements were located between each other in the following order: in the roots of the plant Ca (40%)>K (39%)>P (9%)>Mg (6%)>S (4%)>Na (2%), and in the aerial part of the plant Ca (50%)>K (30%)>Mg (9%)>P (7%)>S (3%)>Na (1%). The highest content of essential trace elements in the composition of the roots and aboveground parts of the D. stramonium falls on the share of Fe (n/h 2015.4521 mg/kg, n/h 1516.3041 mg/kg), and among the conditionally essential microelements Si (n/h 397.8607, n/ch 234.4246). It has been established that the higher content of toxic elements in the composition in the underground part of D. stramonium falls on the proportion of A1 (36.92%) and Ti (35.54%), and in the aboveground part of Ga (48.57%) and Al (17.37%), relative to the total content toxic elements. According to the content of salts of heavy metals of the D. stramonium growing in Uzbekistan meets the requirements established by the Global Fund XIV and WHO. Salts of toxic elements Hg were not found. Comparative data showed that in both organs of D. stramonium growing in Uzbekistan, the content of the considered elements is lower than amount of the element of D. stramonium growing in Kazakhstan and South Africa.
Liver Abscess Due to Migrated Foreign Body

Liver abscess secondary to a migrated foreign body (fish bone) is a rare entity where early diagnosis helps in management and thereby improves the prognosis. We present a unique case of a 47-year-old hypertensive man who presented with high-grade fever, chills, rigors, and abdominal pain. On evaluation, he was found to have a liver abscess secondary to a foreign body (fish bone), although no history of foreign body ingestion was recalled by the patient. Drainage of liver abscess and removal of the foreign body comprise the treatment of choice. We report the successful management of a patient with liver abscess from a migrated fish bone. This case underscores the importance of considering foreign body ingestion as a potential cause of liver abscess, even when patients cannot recall such an event. Timely diagnosis and intervention, along with advances in imaging techniques, contribute to successful outcomes in these rare but challenging cases.
Dostoievski y los escorzos lacerados del alma
Authors: Esteban Ortega Joaquín
Published: March 2024

De manera general se podría decir que en la modernidad ilustrada lo trágico deja de expresarse públicamente en un género cultural específico para ser conducido a los espacios íntimos que el individuo autónomo encuentra en la novela. La resistencia de lo trágico se hace tensión con lo filosófico en el nuevo lugar personal de la literatura. Dostoievski, en esta tesitura, se convierte en paradigma y destino. El presente artículo intenta insistir en la capacidad filosófica de su literatura para hacer transparentes los abismos del alma humana. Veremos cómo únicamente admitiendo las heridas de la existencia se puede decir la verdad. Aunque vaya en ello la vida. En su energía narrativa encontramos la fuerza contradictoria que anima la existencia en el marco del nihilismo y de la compasión. ¿Nos podrá liberar su filosofía trágica de las peligrosas y dogmáticas derivas actuales del idealismo?

Las personas tenemos cuatro dimensiones: la relacional, la física, la psicológica y la espiritual. Las cuatro están interconectadas e influyen unas en las otras de manera continua. A la persona toda realidad le afecta. Somos seres afectivos y conocer nuestra afectividad, conocer qué ocurre en las distintas etapas de nuestra vida en Verdad, Bondad y Belleza puede marcar la diferencia entre vivir una vida en plenitud o no llegar al fondo de los anhelos más profundos del corazón.
Tools for cost management
Authors: Silva Jailson dos Santos , Leite Maria Silene Alexandre
Published: March 2024

This article aims to provide an overview of the literature in which cost assessment methods are currently used, and their characteristics and limitations are also pointed out. To achieve the proposed objectives, a Systematic Literature Review (RSL) was conducted. It was possible to identify the tools discussed in the bibliographic portfolio studied, namely: life cycle costing, target costing, the total cost of ownership, activity-based costing, variable costing, and mathematical models, as well as the difficulties in implementing these tools in different application contexts. It has also been noted that multiple tools are often employed in integrated methodologies to mitigate the inherent limitations of individual models when treated in isolation. The significance of this article resides in its contribution to the discourse on the evolution of cost management tools and their application within integrated approaches, particularly in addressing the typical challenges encountered in emerging business models.
