THE MARGINALISED AND VOICELESS CHILDREN: AN IN-DEPTH LOOK INTO PSYCHO-SOCIAL SUPPORT IN SCHOOLS
Authors: Z Ntshuntshe , J Mathwasa
Published: September 2022

The death of a parent is a traumatic event that has far-reaching consequences for children's lives. Worldwide the number of orphans and vulnerable children has increased, as well as the adversities confronting them. Besides children’s learning schools have become essential for basic human rights. However, recent years have seen an increased emphasis on the provision of psychosocial support for the wellbeing of all children due to the serious consequences orphans and vulnerable children face causing them to miss out on learning. Tertiary institutions in various countries train teachers in Educational Psychology so that they are empowered to give psychosocial support so that they can respond appropriately to the unique challenges faced by vulnerable children in their setting. The purpose of this study was to evaluate the psychosocial support provided to orphans and vulnerable learners in schools. The study used an interpretivist paradigm within a qualitative approach, with semi-structured interviews conducted with four Life Orientation (LO) teachers, two school principals, and two district managers. The data was analyzed thematically. The findings revealed that teachers lacked understanding and expertise in dealing with orphaned learners and were dismissive of the concept of orphaned learners' vulnerability. The study concluded that a variety of factors contributed to the dissonance of support actions, including a lack of coordination and cooperation in the delivery of support to learners. As a result, the study recommends that teachers be trained in how to support orphaned and vulnerable learners and calls for a multisectoral integration of stakeholders in the provision of psychosocial support to orphaned and vulnerable learners.
TINGKAH LAKU PENGUNDIAN ETNIK MELAYU PADA PILIHAN RAYA UMUM KE-14
Authors: M. Shukrimun Muhammad Marwan , Hussin Supyan
Published: September 2022

Buat pertama kali dalam sejarah negara, UMNO/BN tumbang dalam Pilihan Raya Umum ke14 (PRU14). Banyak kerusi yang gagal dipertahankan termasuklah kawasan yang memiliki jumlah pengundi Melayu yang ramai. Perkara ini menimbulkan persoalan, adakah pengundi Melayu sudah tidak memilih parti berteraskan Melayu seperti UMNO? Kajian ini bertujuan melihat faktor yang mendorong pengundi Melayu melakukan perubahan dalam PRU-14. Kajian dilakukan secara kualitatif melalui temubual melibatkan responden yang menjadi pemegang taruh politik dan juga pakar politik negara. Secara umumnya, responden berpandangan rata-rata pengundi Melayu masih mengundi parti berteraskan Melayu atas faktor identifikasi parti dan sosiologi. Walau bagaimanapun, isu-isu yang berbangkit pada PRU-14 menepati teori pilihan rasional apabila ia turut mempengaruhi sebilangan pengundi Melayu. Kesimpulannya, pendekatan politik keetnikan kepada kaum melayu Melayu masih relevan sebagai kaedah meraih undi etnik Melayu. Namun faktor-faktor lain juga perlu diambil kira agar mendapat sokongan yang optimum. Kajian lanjut juga perlu dilakukan terutama terhadap pengundi di lapangan.
Urban Drama: Power Mediation in Antagonistic Copenhagen
Authors: Larsen Jan Lilliendahl , Frandsen Martin Severin
Published: September 2022

Recent research on participation in Danish urban planning has identified three typical formats of engagement: hearings, dialogue meetings, and workshops. Alongside these mainstream approaches, a plethora of less formalized and experimental formats drawing inspiration from collaborative and performative art practices have emerged. However, common to both the mainstream and experimental formats of participation is a difficulty when it comes to dealing with more strategic issues of power in the city. This article introduces and discusses the development, application, and power analytics of a format that focuses on these issues, the conflict and power-mediation method Free Trial! conceived by a local nongovernmental organization as a staged court case for high-profile issues in the city, which straddles political theater, deliberative participation, and research. The article demonstrates that advocacy, agonism, and liminoidity are the core elements that make the format effective in handling contentious issues in a constructive and enlightening manner within its created arena. However, it also shows that the handling of issues of power transcends the limits of this arena. To avoid reproducing unbalanced power relations of the city in general, the core elements of the format need to be incorporated among the wider public through an autonomous organization with this as its primary aim.
Immunomodulation by non-thermal plasma
Authors:   , Mohamed Hager , Krebs Fred C , Miller Vandana
Published: September 2022

Immunological control of disseminated viral infections and cancers of the hematopoietic system can be achieved through robust CD8+ T cell responses. However, immune dysfunctions in patients with these conditions can lead to control failures and disease chronicity. As the first steps toward developing a novel immunological therapy, we investigated non-thermal plasma (NTP), which is a partially ionized gas containing reactive oxygen and nitrogen species (RONS). NTP application to cells induces oxidative stress and stimulates emission of immunogenic damage-associated molecular patterns (DAMPs) known to promote various functions of antigen presenting cells (APCs). These NTP-mediated effects and the resulting augmentation of immune responses were observed in several in vivo cancer models. However, the therapeutic effects of NTP against hematologic viral infections and hematopoietic cancers have not yet been studied. We investigated the immunomodulatory potential of NTP in the context of two challenging hematologic conditions: HIV-1 infection and acute T lymphoblastic leukemia. We hypothesized that NTP can be used to enhance the immunogenicity of the HIV-1-infected T cells or malignant T cells to offset multiple dysfunctions in the immune response in both of these diseases. Application of NTP to the J-Lat CD4+ T lymphocyte cell line, a model for latent HIV-1 infection, resulted in emission of pro-phagocytic and pro-chemotactic DAMPs in addition to modulation of molecules associated with antigen presentation. Accordingly, NTP-exposed J-Lat cells stimulated monocyte migration and maturation, as well as phagocytosis of NTP-exposed J-Lat cells. Similar immunostimulatory effects were observed after applying NTP to the leukemic Jurkat CD4+ T cell line and leukemic THP-1 monocytes, suggesting NTP-mediated immunomodulation as a therapeutic approach for leukemias may also be feasible. These results provide insights for a novel type of treatment in which patient cells are exposed ex vivo to NTP and then injected into the patient as a personalized immunotherapy. These studies provide the foundation for the development of NTP-based immunotherapies designed to boost CD8+ T cell responses that will offer drug-free control of HIV-1 infection, as well as immunological control of hematologic malignancies such as leukemia.
An investigation of accessibility towards educational programming for Syracuse City School District students at local theatre organizations
Authors:   , Borenstein Benjamin , Almanzar Salina , Yau Pamela
Published: September 2022

Despite many researchers attempts to prove the benefits of an arts education such as higher SAT scores and improved cognitive development, the arts have been subjected to a long-standing debate between educators and policy makers about its purpose and impact on student achievement. When comparing artistic programming between suburban and urban school districts, urban students have historically faced inequitable academic curriculums for decades. Theatre organizations have the potential to provide educational arts programming to close the opportunity gap presented by public school systems. Despite the emergence of educational programming at arts organizations, low-income, urban students still face barriers to participating in these programs. This thesis intends to investigate how theatre organizations in Syracuse are overcoming student barriers and creating equitable accessibility to their educational theatre arts programming for all interested participants. Barriers for students in the Syracuse City School District are identified in financial capacity, transportation, language, and institutional stigma.

The goal of the work described in this thesis was to determine if there are detectable amounts of heavy metals in a selection of commercially available e-liquid samples. Both flame and graphite furnace atomic absorption spectroscopy were the methods of analysis employed. A set of preliminary experiments was conducted in order to develop a reproducible method for sample preparation. Once completed, a final set of experiments were performed to quantify the amount of several heavy metals in each e-liquid. The e-liquids analyzed were from the manufacturers Vaporfi, E-liquid Depot, Vuse, and JUUL. The metals detected in one or more of the e-liquids tested were copper, nickel, iron, chromium, aluminum, and vanadium.
Literacy Instructional Coaching in the Realm of Writing
Authors: Abbott Jadelyn
Published: September 2022

Due to the lack of focus on writing in teacher preparation programs and in-service professional development, teachers often feel unprepared to
teach writing. One way to mitigate these feelings is through the use of literacy instructional coaches. Literacy instructional coaches are
specialists who collaborate with teachers to help them develop specific skills, knowledge, and dispositions related to literacy instructional
practices and students’ literacy performance. Existing research indicates that teachers who receive instructional coaching are more likely to
use research-based practices, however, research on writing coaching is minimal. This three-study dissertation explores how literacy coaches
are supporting and influencing teachers in writing and writing instruction. Additionally, I examined if and how coach self-efficacy influences
their writing coaching practices. In this study, 66 K-6 teachers who are receiving literacy instructional coaching and 115 K-6 coaches completed
a researcher-created survey.

In Study I, I used mixed methods procedures to examine how coaches and teachers perceive their instructional coaching related to teaching (1)
writing across the curriculum, (2) stages of the writing process, and (3) writing skills. Findings suggest that coaches support teachers in
English Language Arts writing but are less frequently supporting teachers in disciplinary writing methods for diverse learners. Additionally,
multiple chi-square analyses suggest that coaches and teachers sometimes do not hold the same perception of the frequency of coaching writing
practices employed within the K-6 setting. Implications for both researchers and practitioners are discussed.

In Study II, I used survey responses to explore how teachers perceive writing coaching to impact their knowledge, skills, and dispositions
toward writing and writing instruction. Results indicate that teaching in writing is sparse, but those who do receive coaching feel more
competent and confident in writing instruction. Teachers’ preferred writing coaching practices are explored.

Lastly, in Study III, I explored if and how self-efficacy for writing, writing instruction, and teaching writing elements relates to instructional
coaches’ use of research-based writing practices during their coaching sessions. Through analysis of multiple logistic regressions, I identified that
self-efficacy for writing and teaching writing elements predicts the likelihood of a coach using research-based writing practices, while self-efficacy
for writing instruction was not a significant predictor of any practices. Implications for administrators and professional development agencies are discussed.
Biophysical Insights into the Transport Properties of Lysenin Channels
Authors: Bogard Andrew Merlin
Published: September 2022

The defense work focused on deciphering novel functionalities of lysenin channels with respect to adjustment of their
regulation and transport properties in response to environmental changes. Lysenin is a pore-forming toxin extracted from
the earthworm E. fetida, which self-assembles into large pores in artificial and natural lipid membranes containing sphingomyelin.
Prior investigations on their functionality identified strong regulation by voltage and ligands as fundamental traits of lysenin,
similar to ion channels. In addition, stochastic sensing, controlled switching, and hysteretic conductance have been added to the
list of intricate biophysical properties of lysenin channels as potential enablers of biotechnological and biomedical applications.
Our work employed electrophysiological measurements of lysenin’s biophysical activity in various environmental conditions. The first
important feature we discovered is the unusual selectivity of lysenin channels for monovalent anions and cations, which is uncommon
for pore-forming toxins. In the same line, we exploited the ability of divalent cations to force the lysenin channels into a stable
sub-conducting state and assessed how such conformational changes modulate their selectivity. Experimental and theoretical approaches
indicated that sub-conductance is accompanied by a substantial loss of selectivity, leading to the dissipation of the electrical gradients.
Next, our work focused on investigating the influence of Cu2+ ions on the functionality of lysenin channels. The major finding of these
experiments is that Cu2+ addition influences the hysteretic conductance to such an extent that lysenin behaves like a
memory molecule capable of preserving information about its immediate history in the absence of any applied voltage. Also, we
identified that addition of Cu2+ restores the voltage-induced gating of lysenin channels reconstituted in neutral
lipid membranes, known to suppress the voltage regulation. In conclusion, our results identified unusual biophysical properties
of lysenin channels which may be further exploited not only for understanding novel biological activities of transmembrane
transporters but also for potential use in biotechnology, bioengineering, and bioelectronics.
Overview of the causes and types of recurrent cystitis

Published: September 2022

Bacterial cystitis accounts for the majority of urinary tract infection (UTI). It is frequently found in young, otherwise healthy females showing no signs of anatomical or physiological urinary tract defects. Among young women who have experienced an episode of acute bacterial cystitis, 25% to 50% develop recurrent episodes. Individuals with recurrent cystitis episodes have a greater susceptibility to urogenital colonization with uropathogens that thrive by adhering to uroepithelial cells. Further, there is an increased likelihood of infection with an antibiotic resistant uropathogen due to previous antimicrobial therapy for recurring infections. At each step of the pathogenesis, different host genetic, biologic, and behavioral factors, and bacterial factors interact and influence susceptibility to recurrent cystitis. Behavioral factors like sexual intercourse, use of spermicidal contraceptives and history of recurrent cystitis are major independent risk factors for recurrent cystitis infections. In post-menopausal women without comorbidities, estrogen depletion is mainly responsible for increased susceptibility to recurrent cystitis. Certain strain-specific bacterial virulence determinants may also contribute to recurrent cystitis by providing a selective advantage. Phenotypically, recurrent cystitis is categorized as reinfection or bacterial persistence. Majority of recurrent cystitis cases seen in men occur due to structural or functional abnormalities of the urinary bladder which allows same pathogens from the same site in the bladder to cause recurrences due to bacterial persistence. The concept of ‘uncomplicated’ and ‘complicated’ recurrent cystitis is used for classification of recurrent cystitis cases, similar to UTIs. Uncomplicated recurrent cystitis comprises cases occurring in young, healthy, nonpregnant women, mainly due to uropathogenic Escherichia coli. Due to the unique spectrum of host-bacterial interactions in the urinary tract, the distinction between complicated and uncomplicated recurrent cystitis is not straightforward. ‘Complicating’ factors such as structural, obstructive, neoplastic, functional, and neurological abnormalities of the urinary tract, systemic conditions including pregnancy, and certain demographic factors are attributed in the development of complicated recurrent bacterial cystitis.

Published: September 2022

Inflammation, which manifests as pain and swelling, forms the basis of various dental pathologies like dental caries and pulpitis. Inflammation is also associated with tissue injury in cases of surgical processes like tooth extraction, root canal treatment or third molar extraction. Various drugs which help reducing inflammation are used in the treatment of dental pathologies. In this article, the mechanism of action of trypsin, bromelain and rutoside is mapped to show the clinical benefit. To demonstrate comparative benefit of trypsin, bromelain, and rutoside combination, a literature search was carried out for real-world investigator-initiated studies. A qualitative analysis of these studies was carried out. All 7 studies, identified in literature, controlled clinical studies comparing efficacy and safety of combination of trypsin, bromelain, and rutoside with that of non-steroidal anti-inflammatory drugs like diclofenac, versus other anti-inflammatory enzymes like trypsin-chymotrypsin combination or serratiopeptidase. All studies have demonstrated efficacy benefit of combination of trypsin, bromelain and rutoside. Importance and place of trypsin-bromelain-rutoside combination in therapy of dental pathologies, is further emphasized based on the results of this review.

Authors: Mangla Aarushi , Vasani Hetal , Vegad M M
Published: September 2022

Metallo-beta-lactamase (MBL) producing Pseudomonas is a worrisome pathogen to hospital infection control due to production of resistance to multiple antibiotics. So, treatment options are narrowed down to only few antibiotics which will result in high morbidity and mortality. This study was conducted with the aim to detect prevalence of MBL producing Pseudomonas aeruginosa and to compare the different phenotypic methods for the detection of MBL production in Imipenem resistant clinical isolates of Pseudomonas aeruginosa.

: In this prospective study total of 14,145 different clinical samples received from different wards. Out of which 804 Pseudomonas aeruginosa were isolated and antibiotic sensitivity testing was done by Kirby-Bauer disc diffusion method using CLSI guidelines. These were evaluated for Carbapenems resistance and MBL production. Imipenem resistant strains were subjected to screening tests like Double-disc synergy test, Combined disc diffusion test (CDT) and Modified-Hodge test.

: In our study out of 804 isolates,153(19.02%) isolates are resistant to Imipenem. Out of 153 Imipenem resistant isolates, Combined disc diffusion test was positive in 100%, Double disc synergy test in 76.5% and Modified-hodge test in 84.15% isolates.

: Combined disc diffusion test is very sensitive, cost effective and convenient screening test for detection of MBL producing Pseudomonas aeruginosa. So, all Imipenem resistant Pseudomonas isolates should be regularly screened for detection of MBL by Combined disc diffusion test (CDT) to prevent spread of resistance, longer hospital stay and treatment failure.
A Contribuição dos Estudos Discursivos Foucaultianos para uma Análise das Práticas de Liberdade no Espaço Heterotópico AzMina
Authors: Faria Bruna , Zíngara Andréa
Published: September 2022

O objetivo deste texto é apresentar uma reflexão acerca da produtividade dos estudos discursivos foucaultianos na e para análise de enunciados veiculados pela revista eletrônica AzMina em março de 2020. Primamos, no entanto, por um recorte, a partir de um gesto de leitura e de interpretação de uma sequência discursiva de autoria do Presidente da República em exercício, Exmo. Sr. Jair Messias Bolsonaro, publicada no referido veículo. Entendemos que esse espaço deu e dá voz ao sujeito feminino vítima de violências de cunho machista materializadas nos corpos das mulheres no período de isolamento social durante a pandemia provocada pelo novo Coronavírus. Para isso, lançamos mão das noções foucaultianas de heterotopia (2001), de contraconduta (2004), de dispositivo (1999) e de biopolítica (2008), pois quando articuladas tais noções promovem a compreensão do modo de construção de um espaço heterotópico configurado nessa revista ao gerar novas significações, valores e inspirar, por meio da desestabilização das convenções, outros projetos de vivência, representando as mulheres em sua heterogeneidade ao mesmo tempo em que demonstram a atualidade do pensamento do filósofo Michel Foucault para análises de discursos.
Does ENSO Significantly Affect Rice Production In Indonesia? A Preliminary Study Using Computational Time-Series Approach
Authors: Herho Sandy H. S. , Brahmana Ferio , Herho Katarina E. P. , Irawan Dasapta E.
Published: September 2022

ENSO is a phenomenon that is suspected to inﬂuence rice production in Indonesia. In this study, we try to ﬁnd direct correlation between ENSO and rice production in this region by using various latest computational time series methods, such as Dynamic Time Warping, Wavelet Coherence, and Bayesian Structural Time Series to quantify the statistical relationship between the Multivariate ENSO Index on annual rice production in 1961- 2019. We did not ﬁnd a direct correlation between these two variables, which may be due to the local inﬂuence of ENSO on different rice production areas in Indonesia. This study would also point out the importance of shifting the theme of research in Indonesia from mapping to monitoring and freely share the data. This step would bring science to progress further and faster.
Interpretation of the Results of Particle Size Analysis of Soils by Various Schools of Soil Science
Authors: Bezuglova O.S. , Boldyreva V.E. , Morozov I.V. , Tagiverdiev S.S. , Gorbov S.N.
Published: September 2022

The article discusses a few of today's applicable soil classifications in terms of their texture: the one by A. Kachinsky (Russians) and other two – by the US Department of Agriculture (USDA) and the World Reference Base for Soil Resources (WRB). The article also presents several discrepancies in the nature of the source of research (primary soil particles), the width of the borders of the key textural classes, and also in the need to take into account possible ways of their formation when classifying. Bearing it in mind, we have studied 57 separate soil samples of the Calcic Chernozem of the Rostov Region. The comparative study of the results of the particle-size distribution analysis was performed based on the results obtained with the help of the laser diffraction method, since it is not directly related to any of the above classifications, thus being free from whatever lasting stereotypes. The choice of options for the conditions of soil formation as presented in the Russian classification seems a key decisive parameter while interpreting experimental results. In the example under consideration, this classification allows for defining the variety of a textural class as clay (from light to heavy) depending on what type of soil formation the sample may be related to. Due to some discrepancies in determining the boundaries of the textural classes, we have observed redistribution of primary soil particles whereas their factual amount remains unchanged. All these differences are vital nowadays in view of globalization and boost in the number and importance of international research.

Since 1978, China's inbound tourism market has maintained a stable and rapid development trend. The period of rapid growth of inbound tourism in China began in 1986. More than 55 million travelers from all over the world visit China every year. At present, China's tourism industry has entered the stage of rapid development and has become an important industrial sector of the national economy. The comprehensive contribution of tourism to China's GDP has reached about 11 %. The total number of direct and indirect jobs in the tourism industry now accounts for 10.3 % of the country's total employed population. Today, China ranks fifth to sixth in the world in foreign exchange earnings from tourism. China's East, South, Southwest and Center have the highest demographic and accommodation capacity for tourism development. China's regular and high-speed rail network is also confined to these regions of the country. South Korea, Japan, the USA and Russia are among the leading inbound tourist donor countries. China annually receives about 5 million tourists from South Korea. Europe and America, which have high GDP per capita, also provide a large flow of tourists. Among the thirty-one provincial areas in China, Beijing, Liaoning, Shanghai, Jiangsu, Zhejiang, Shandong and Guangdong, which are located in the economically developed provinces and coastal areas in the east and south, have the most tourist arrivals, more than 3 million. Currently, the tourism industry in China is developing steadily, the inbound tourism market continues to grow at a high pace.

Authors: CANDAN Merve , YILDIRIM Salih
Published: September 2022

Objectives: Transmission from asymptomatic patients is one of the biggest challenges in controlling the Coronavirus disease 2019 (COVID-19) outbreak because these cases are a potential source for disease spread. Based on this situation, the aim of our study is to determine the prevalence of COVID-19 in asymptomatic pediatric dental patients representing Sivas and surrounding provinces.
Methods: The population of the study consists of pediatric patients between the ages of 0-14 who applied to Sivas Oral and Dental Health Hospital General Operating Room for dental treatments between July 2020 and August 2021.
Results: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was detected in only 5 patients (approximately 1.80%) out of 278 asymptomatic pediatric patients.
Conclusions: It is thought that the COVID-19 infection, which threatens the whole world, can progress asymptomatically in children, and therefore it may be a risk factor for the spread of the infection. To tackle the COVID-19 pandemic, it is recommended to maintain a high level of infection control measures in schools and day-care and to implement widespread testing on a global scale targeting the pediatric population.

Published: September 2022

Background: B. canis infections have been reported in many countries of the world. B.canis can cause infections both in dogs and human beings. It can be transmitted to human via laboratory accidents during handling and contact with sick dogs. is an infectious agent for humans and it is transmitted to humans by various ways including laboratory accidents and contact with sick dogs. Methods: In this study serum samples were collected by using stratified random sampling method from the Diyarbakýr Metropolitan Municipality Animal Care and Rehabilitation Center, where approximately 600 dogs were housed. Result: Out of 83 samples, 9.6% and 26.5% of serum samples were found as positive by B.canis RSAT and B.canis ELISA, respectively. While 6% and 9.6% of the samples were positive by B. abortus S99 RSAT and B. abortus ELISA, respectively. Sensitivity and specificity of B. abortus S99 ELISA was 98% and 95.5%, respectively. On the other hand, sensitivity and specificity of B.canis M(-) ELISA was 96.6% and 94%. As a result, it was concluded that B. canis infection is common in dogs and this should be considered both for dogs and public health. Unfortunately, there is no standardized commercial serological test for diagnosis of B.canis and other rough Brucella species currently. This is the main reason that rough brucella infections might not represent the real B.canis infection situation. Therefore, most of the cases have the possibility of being undetected. For this reason it is utmost important that B.canis RSAT and ELISA can be used as routine tests in the hospitals and veterinary clinics in the serological diagnosis of brucellosis.
Predictors of Women’s Childbirth Experience: A Prospective Longitudinal Study on Italian New Mothers
Authors: Molgora Sara , Campo Emanuela , Carones Maurizio Barbieri , Ferrazzi Enrico , Saita Emanuela , Facchin Federica
Published: September 2022

BACKGROUND

Women’s memories of their childbirth experience tend to remain unchanged over time. This experience can be influenced by obstetric factors as well as by sociodemographic and psychological variables.

OBJECTIVE

To examine whether women’s perceived childbirth experience changes over time; to identify the predictors (obstetric, sociodemographic, and psychological variables) of this experience immediately after delivery and after 3 months.

METHODS

This prospective longitudinal study comprised two hundred and twenty-one Italian women who completed a self-report questionnaire at two assessment points: immediately (1–3 days) after birth (Time 1) and 3 months postpartum (Time 2). At Time 1, the questionnaire included some questions on sociodemographic, psychological, and obstetric information, and the Wijma Delivery Experience Questionnaire (WDEQ(B); at Time 2 women compiled again the WDEQ(B).

RESULTS

Repeated measures ANOVA revealed that the childbirth experience did not change from Time 1 to Time 2. However, predictors of this experience were different between Time 1 and Time 2: at Time 1, the childbirth experience (WDEQ(B)_t1) was significantly predicted nly by type of cesarean section; at Time 2, the childbirth experience (WDEQ(B)_t2) was significantly predicted by WDEQ(B)_t1, history of psychological disorders, and type of conception.

DISCUSSIONS

Our findings enhance the understanding of the main predictors of a woman’s childbirth experience. Identifying areas of vulnerability is important for clinical practice, as well as for developing maternal health policies to improve women’s birth experiences, postpartum well-being, and the baby’s development.

OBJECTIVE

To determine the effect of childbirth preparation education on the prenatal adaptation of pregnant women.

METHODS

This study design was a quasi-experimental; one-group pretest-posttest. This study was conducted with the participation of 42 pregnant women and their spouses. The educations were given in four sessions in a special area designed for childbirth preparation educations in a private hospital where the study was conducted. The data of the study were collected using the Pregnant Women Information Form and the Prenatal Self-Evaluation Questionnaire. Prenatal Self-Evaluation Questionnaire consists of seven subscales which are the well-being of pregnant women and their infants, acceptance of pregnancy, acceptance of motherhood, fear of childbirth, relationship with her mother and relationship with her spouse. The Wilcoxon signed rank test statistics were used to analyze the difference between the pretest and posttest PSEQ scores.

RESULTS

The concerns about the well-being of pregnant women and their infants (p < .05), acceptance of pregnancy (p < .05), acceptance of motherhood (p < .05), fear of childbirth (p < .05), relationship with her mother (p < .05), relationship with her spouse (p < .05) subscale and total adaptation score (p < .05) were significantly higher before the education compared with the after the education. However, there was no significant difference between pre and post-education scores regarding readiness for birth subscale (p > .05).

CONCLUSION

This study showed that childbirth preparation education improves prenatal adaptation, acceptance of pregnancy and motherhood, relationship with her mother and relationship with her partner of pregnant women. In addition, it decreased fear of childbirth of pregnant women.

BACKGROUND

Perceived control and support can contribute to a positive childbirth experience. However, most studies have not differentiated between perceived internal and external control.

OBJECTIVE

The present study aimed to assess primiparous women’s perceived internal control, external control, and support, including family and professional support and their association with the childbirth experience.

METHODS

A cross-sectional study was carried out on 800 primiparous mothers recruited from health centers across Tabriz, Iran, through cluster sampling. The childbirth experience questionnaire (2.0) and the support and control in birth scale were used to measure women’s childbirth experience and their perceived internal and external control and support. Data were collected through an interview during early postpartum and analyzed by independent t-test, one-way ANOVA, Pearson correlation and general linear model.

RESULTS

The results demonstrated a significant correlation between perceived internal control (r = 0.80, p < .001), external control (r = 0.79, p < .001) and professional support (r = 0.83, p < .001) with childbirth experience. By controlling confounders such as socio-demographic and reproductive variables, internal control [β (95% CI): 0.28 (0.25 to 0.31); p < .001], external control [0.10 (0.06 to 0.14); p < .001], professional support [0.27 (0.23 to 0.30); p < .001], were independent predictors of positive childbirth experience.

CONCLUSION

These findings point to the importance of perceived internal, external control and professional support and the relationship between healthcare providers, especially midwives, with the women in improving childbirth experience. It is suggested that healthcare providers give support to women and utilize methods that enhance women’s control during labor and childbirth.

Pemanenan singkong masih banyak dilakukan secara manual dengan menarik atau mencabut batang ubi kayu yang sudah siap panen. Penelitian ini bertujuan untuk mengetahui besarnya gaya yang diperlukan untuk mencabut batang ubi kayu. Penelitian dilakukan di lahan petani di Desa Bandar Agung, Kecamatan Bandar Sakti, Lampung Tengah. Sampel ubi kayu sebanyak 50 pohon dipilih untuk mewakili bagian tengah dan empat pinggir pada tanah seluas 1-ha berukuran 50-m x 200-m. Pengukuran gaya pencabutan ubi kayu dilakukan menggunakan kerekan yang ditopang rangka kaki tiga dari pipa besi dan dilengkapi dengan timbangan ayam 100 kg dan tali. Parameter yang diamati meliputi gaya pencabutan batang ubi kayu, kadar air tanah, kekerasan tanah, lingkar batang, tinggi tanaman, berat umbi singkong. Hasil penelitian menunjukkan bahwa gaya pencabutan ubi kayu berkisar dari 20 kg (196 N) hingga 70 kg (686 N) dengan rata-rata 44,9 kg (440,2 N). Hasil penelitian juga menunjukkan bahwa gaya pencabutan ubi kayu turun dengan naiknya kadar air tanah. Faktor tinggi tanaman, lingkar batang, dan bobot umbi juga berpengaruh positif terhadap gaya pencabutan ubi kayu.

We designed a high-precision fertilizer applicator to distribute fertilizer with the required dose at every specified point. The dose necessary aims to meet the nutritional needs of plants, so that plant growth is more effective while reduce waste. The fertilizer applicator was designed to have an auger and drive system that can discharge the fertilizer precisely. A 3D CAD model of the applicator was created to conduct a discrete element simulation to predict the discharge fertilizer process. Experiment was carried out to validate the simulation model. The experiment utilized a small-scale applicator prototype manufactured by 3D printing. A small electric actuator controlled by Arduino microcontroller was installed to rotate the auger. The auger can push and release the fertilizer precisely depending on the rotation's number. Both simulation and experiment results were compared and showed a small error of 6.42%. The results show our designed fertilizer applicator have good accuracy and precision, which indicates the applicator was suitable to distribute fertilizer uniformly.

Multidão, solidão
Authors: Loiola Rita
Published: September 2022

A solicitação endereçada ao leitor é elemento central da constituição da poética de Charles Baudelaire. Em alguns poemas em prosa reunidos no título póstumo O spleen de Paris, a relação entre poeta e leitor parece se estabelecer por meio da encenação do sujeito poético como um leitor levado aos limites da razão. Este artigo busca apontar alguns aspectos dessa dramatização do poeta como intérprete que por vezes fracassa diante do real, confrontado com a própria incapacidade de decifração. A leitura partirá de aproximações entre o poema em prosa “As multidões”, de Baudelaire, do conto “The Man of the Crowd”, de Edgar Allan Poe, traduzido pelo poeta, e de trechos dos Paraísos artificiais, buscando examinar a relação entre os termos “solidão” e “multidão” e uma certa fluidez ou indeterminação da constituição do sentido. Pretende-se, assim, apontar de que maneira a representação do poeta como um exegeta nem sempre bem-sucedido diante da promessa de significados pode estar operando na construção do que se poderia chamar de uma “poética da contradição” do texto baudelairiano.
