Effects of Photoperiod and Ethephon Treatment on Abscisic Acid Levels in Chrysanthemum morifolium Ramat.1
Authors: Sengupta Syamal K. , Rogers Marlin N. , Lorah Esther J.
Published: August 2022

Concentrations of abscisic acid (ABA) in purified extracts of ‘#3 Indianapolis White’ were measured with a gas liquid chromatograph (GLC) and confirmed by combined gas chromatography-mass spectrometry (GC-MC). Apices contained 1½ to 3 times as much ABA as young or old leaves. Plants under long day (LD) treatment contained more ABA than those receiving short days (SD). ABA levels in the apices of plants sprayed with ethephon, (2-chloroethyl) phosphonic acid, and receiving 2 or 3 weeks SD, were lower than in plants given only 2 or 3 weeks SD.
Predicting Stages of Sweet Corn (Zea mays L.) Development1
Authors: Arnold Charles Y.
Published: August 2022

The characteristics, limitations, and accuracy of 3 thermal (heat) unit systems were examined. One was a modified polynomial regression system and 2 were base temperature : cutoff temperature systems. All gave about the same minimum coefficient of variation if the proper parameters were used. Distinct differences were noted for the temperature-rate relationships found in 3 periods: planting to the 4th leaf, 4th leaf to silk, and silk to harvest.

No consistent advantage was found for maximums alone, minimums alone, or both maximums and minimums as independent variables over the use of the mean daily temperature. Planting dates used alone or in conjunction with thermal units were effective sometimes in reducing error of the predictive system. It is hypothesized that they reflect differences in climatic factors that show a trend during the growing season. The estimation of the 4th leaf stage failed to increase the accuracy of the prediction of silking or harvest dates enough to make the effort practical. The establishment of the 80% silking stage by field observation increased the accuracy of harvest date prediction.

The use of the Barger base temperature : cutoff temperature system with appropriate parameters is recommended.
Bean Yellow Mosaic and Tomato Ringspot Virus Influence on Growth and Elemental Content of ‘Dark Red Kidney’ Bean (Phaseolus vulgaris L.)1
Authors: Fries R. E. , Bergman E. L. , Boyle J. S.
Published: August 2022

Greenhouse nutrient cultures with lx and 2x modified Hoagland solutions were used to study the influence of bean yellow mosaic and tomato ringspot virus isolates on elemental content of plant parts of ‘Dark Red Kidney’ beans. All isolates reduced fresh and dry wt of plants. Plants grown in 2x solution were somewhat smaller than those treated with lx solution.

Solutions increased in pH and conductivity but decreased in volume. Control solution volumes decreased more while pH’s and conductivities increased more than those of comparable solutions containing virus-infected plants. Control plants absorbed more total P, K, Ca, Mg, Mn, and B from the solutions than inoculated ones.

Both increases and decreases in nutrient content of bean plants resulted from virus infection, higher concentrations and total amount of Mn in virus-infected plant parts and a possible association between plant K level and the amounts of water absorbed by roots was observed. Interpretation of elemental content has to be based on virus and/or isolate, plant part sampled, time of sampling, nutrient solution concentration and element.

Giving assignments as an assessment in online learning during the pandemic needs to be well-considered properly so that students are not frustrated with the piling up tasks but are unable to give educators an idea of ​​students' concepts understanding. This qualitative study aims to describe students’ responses to assignments in the form of journal writing in the Real Analysis course. The research was conducted by asking 109 students who took the Real Analysis class to write journal. At the end of the semester, students were asked to fill out a survei to find out the student's response to the task of writing a journal. Several students were then interviewed to get a more detailed information of the responses given in the survei. The results showed that 94% of the 109 students considered journal writing assignments need to be given in the Real Analysis course. As many as 99% of students agree that the feedback given by the lecturer helps students understand the material. Finally, 94% of students agree that journal-writing assignments are effective for improving understanding in the Real Analysis course. The results of the analysis of journals written by students showed that on average, more than 80% of students wrote notes related to concepts they had previously. It shows a meaningful learning process so that journal-writing assignments can be an alternative to achieve meaningful learning, especially in online learning during a pandemic.
Supervisor-Supervisee Relations and Job Performance: Study of Healthcare Field Officers in Chongwe, Zambia
Authors: Maseko Dalitso
Published: August 2022

The power of praise in the workplace can move employees from apathy or resentment to happiness and productivity. Reinforcement such as positive reinforcement makes people feel appreciated and encouraged, which can be motivating and rewarding. An observational study aimed at examining the relationship between motivation and employee performance using through the lens of the Reinforcement Theory of Motivation and The Law of Effect was conducted on a Team of Healthcare Field Workers. Purposive sampling of twenty (20) Healthcare Field Workers from Chongwe Rural District of Zambia was done with whom a series of both negative and positive reinforcement strategies were applied. The final outcome of the study revealed a significant positive change from 5% to 30% of the overall staff performance on the targets in just four (4) weeks. Such an outcome definitely demonstrated that by carefully and genuinely using a system of positive or negative reinforcements, individuals can learn the correct set of responses for any given stimulus especially in relation to their job performance. Research reveals that when managers are more supportive of autonomy, employees perceive the value of their work efforts and are able to perfom as expected.
The Correlation between Sleeping Patterns and Academic Performance for TAU Medical Students
Authors: Erebe Tiffany
Published: August 2022

Sleep is very essential to promote proper functioning as human beings. Yet, in the “medical society”, whether as a student or practitioner, it’s a known fact that a lot of individuals struggle with different types of sleep disorders of varying degrees. Recent studies have been able to shed light on the detrimental effects of inadequate sleep on the general health and productivity of a person. The Circadian rhythm dictates the body’s natural bedtime-wakeup schedule. The better the quality of sleep, the less likely we are to experience significant daytime sleepiness. When a student has to do 8 courses, go to school for 10 hours and do extracurricular activities like volunteering, the time it will take to cover all of those tasks, sleep seems almost impossible for medical students. Regardless of whether previous students, now practitioners, were able to complete these tasks does not indicate that there is no problem. It is important we research this correlation because we need to know if this aspect in our day-to-day lives affects our outcome in academics. As students, we are expected to do a lot in a short span of time and pass exams with flying colours. As such, we must investigate one of the proposed factors that leads to poor academic performance in students. For the purpose of this research, our sample community would be limited to Texila American University Students in MD1-MD4. Keywords: Academic, Medicine, Performance, Pittsburgh, Students, Sleep.
A Comparison of Students’ Attitude and Perception towards Morning or Afternoon Classes in Texila American University, 2021
Authors: Adams Ramona
Published: August 2022

This paper reports on the findings from focus groups conducted at Texila American University on the attitudes of its medical students towards morning lectures. Students felt that two things were vital for a good lecture: (1) that the lecturer goes beyond what is written in the lecture notes; (2) that the lecture is interactive, by which students meant that the lecturer asks if students understand concepts and adjust the delivery accordingly, and the lecturer answers the students’ questions. The students in the focus groups also discussed what makes for a bad lecture: (1) lecturers reading straight from slides; (2) lecturers who ‘blame the students’ by saying that students don’t work hard enough and are too lazy to turn up to lectures; and (3) lecturers who cover the material too slowly or too quickly. The most prominent reason given for not attending lectures was the timetabling of lectures in such a way that students had too few classes in one day to make the sojourn to university worthwhile and relating to feelings of tiredness each afternoon. Any university seeking to improve attendance at lectures should perhaps look as much to improving its timetabling practices as it does to improve the practices of its individual lecturers. Keywords: Focus groups, Lectures, Student attitudes.
Farklı Yetersizlik Türlerinden Etkilenen Çocuk ve Gençlerin Duygu ve Davranış Bozukluklarının Değerlendirilmesi
Authors: UĞURLU Mahir , ERATAY Emine
Published: August 2022

Giriş: Araştırmada farklı yetersizlik türlerinden etkilenen çocuk ve gençlerin duygu ve davranış bozukluklarının belirlenerek değerlendirilmesi amaçlanmıştır.Yöntem: Araştırmada nicel araştırma yöntemlerinden genel tarama araştırma modeli kullanılmıştır. Araştırmanın verileri 6-18 Yaş Çocuk-Gençler için Öğretmen TRF ölçeği ile 1439 çocuk ve gencin 501 öğretmeninden toplanarak SPSS 23 programıyla analiz edilmiştir.Bulgular: Yetersizlik türü ile duygu davranış bozuklukları arasında anlamlı farklılık bulunmuş; TRF ölçeğinden en yüksek puanı otizm spektrum bozukluğu olanlar, en düşük puanı ise görme yetersizliği olanlar almıştır. Erkeklerin kızlara göre ve çoklu yetersizliği olanların olmayanlara göre daha yüksek puan aldığı bulunmuş; eğitim kademesiyle birlikte TRF ölçeğinden alınan puanların arttığı belirlenmiştir.Tartışma: Araştırmada kurallara karşı gelme alt ölçeği dışındaki diğer alt ölçeklerde en yüksek puana OSB olan bireylerin; tüm alt ölçeklerde en düşük puana ise görme yetersizliği olan bireylerin sahip olduğu bulunmuştur. Bulgular literatürdeki yetersizlik türünün duygu ve davranış problemleri üzerinde etkili olduğu bulgusuyla benzerlik taşımaktadır. Bu durum üzerinde yaşadıkları iletişim ve sosyal etkileşim güçlükleri, akran ilişkileri ve oyun becerilerindeki sınırlılıklar, başkalarının düşünce ve yargılarını anlamada güçlük çekmelerinin etkili olduğu düşünülmektedir. Duygu ve davranış bozukluklarının etkilerini azaltmak için öğrencilere, öğretmenlere ve ailelere yönelik programlar hazırlanabileceği, araştırma verilerinin öğretmenlerden olduğu gibi ebeveyn bildirimleriyle de elde edilebileceği, araştırmanın 3-6 yaş arası çocukları kapsayacak şekilde yapılabileceği önerilerinde bulunulmuştur.

Published: August 2022

Bacillus subtilis is a Gram-positive bacterium that has gained an unprecedented reputation as an expression system at the industrial scale due to characteristics such as GRAS (Generally recognized as safe), ease of genetic manipulation, high growth rate on the cheap substrate, and short fermentation cycle. This expression system has been widely accepted for the production of various chemicals, pharmaceutical products, food products, proteins, and enzymes. But there are various hurdles to optimized production of heterologous protein in this expression system due to a lack of understanding regarding metabolic pathways and expression elements. In this review, we have emphasized strategies that can enhance the expression level of heterologous proteins in B. subtilis. These strategies included optimization of B. Subtilis strain, expression elements such as promotors, UTR (Untranslated region), RBS (Ribosome binding site), signal peptide, and metabolic pathways. Finally, contemporary challenges and future perspectives of B. subtilis as an industrial scale expression system were discussed.

Effects of Maternal Diet during Pregnancy or Lactation on the Development or Prevention of Allergic Diseases in Offspring
Authors: Kim Ja Kyoung
Published: August 2022

The increasing prevalence of allergic diseases in the past decades has been caused by environmental rather than genetic factors. Recent research has focused on the relationship between the mother’s environmental exposure, especially during pregnancy, and allergic outcomes in the offspring. Intervention studies to prevent allergic diseases have also been conducted. Environmental factors, such as diet induce changes in the mother's intestinal flora, and the signals generated have a permanent effect on the fetal immune development through an epigenetic mechanism, which may be involved in disease development. This review outlines whether dietary patterns in mothers are related to allergic diseases, and it summarizes whether supplementation with micronutrients, such as omega-3 unsaturated fatty acids, vitamin D, and folic acid can prevent allergic diseases. Studies have found that a westernized diet is associated with an increase in the prevalence of allergic diseases; however, intervention studies conducted with micronutrients or probiotics do not provide clear results regarding its preventive effect. A mother’s diet during pregnancy or lactation may affect the health of the child. Well-designed intervention studies are warranted to attempt to prevent allergic diseases. Consequently, good dietary patterns based on high-quality evidence are recommended for pregnant and lactating mothers.

Authors: Kim Jeung-Im
Published: August 2022

Purpose: To pool preliminary items based on nine domains as the first phase of developing a preterm birth risk assessment scale (PBRAS).Methods: Item generation was performed using deductive methods, such as literature review and related scales, and inductive methods through in-depth interviews with 11 preterm birth (PTB) women, and ex­perts validated the content. The experts were clinical nurses who worked in delivery rooms, and professors who taught on the subject of women's health nursing. Preliminary survey for 32-item was conducted among 27 women with PTB.Results: After item generation and pooling for the PBRAS, a total of 84 items were developed. A 32-item questionnaire was integrated with rigorous review by experts. Internal consistency of the 32-item PBRAS had a Cronbach alpha of 0.90. The PBRAS was significantly correlated with pregnancy stress (r= 0.77, p<0.001), somatic awareness scale (r=0.72, p<0.001), and risk scoring for PTB (r=0.44, p<0.001).Conclusion: The 32-item PBRAS has content validity, but exploratory and confirmatory factor analyses for the 2nd phase of scale development needs to be performed.

Authors: Woo Minyoung , Chae Sun-Mi
Published: August 2022

Purpose: To examine the mediating effects of parental efficacy on the relationship between participating in online parenting communities and health-promoting behaviors for children among first-time mothers with infants and toddlers.Methods: The participants were 174 first-time mothers who used online parenting communities. Data were collected through self-report online questionnaires. Descriptive statistics, independent t-test, 1-way analysis of variance, Pearson correlation coefficient and multiple linear regression analysis were performed. The significance of the mediating effect was verified using the Sobel test and PROCESS macro.Results: Significant predictors for health-promoting behaviors for children among first-time mothers were maternal age, maternity leave, monthly income, weekly use of online communities, daily use of online communities, satisfaction with online communities, and parental efficacy, which explained 51.0% of maternal health-promoting behaviors for children. Parental efficacy partially mediated the relationship between mothers’ satisfaction with using online communities and their health-promoting behaviors for children.Conclusion: Interventions to enhance satisfaction with online parenting communities and parental efficacy should be developed to promote the health of infants and toddlers. Therefore, it is necessary to consider the needs of mothers for child rearing and health care, and develop online parenting communities that can provide qualitative health information and enable safe online interactions between mothers.
The Perceived Effectiveness of Secure Messaging for Medication Reconciliation During Transitions of Care: Semistructured Interviews With Patients
Authors: Brady Julianne E , Linsky Amy M , Simon Steven R , Yeksigian Kate , Rubin Amy , Zillich Alan J , Russ-Jara Alissa L
Published: August 2022

Background

Medication discrepancies can lead to adverse drug events and patient harm. Medication reconciliation is a process intended to reduce medication discrepancies. We developed a Secure Messaging for Medication Reconciliation Tool (SMMRT), integrated into a web-based patient portal, to identify and reconcile medication discrepancies during transitions from hospital to home.

Objective

We aimed to characterize patients’ perceptions of the ease of use and effectiveness of SMMRT.

Methods

We recruited 20 participants for semistructured interviews from a sample of patients who had participated in a randomized controlled trial of SMMRT. Interview transcripts were transcribed and then qualitatively analyzed to identify emergent themes.

Results

Although most patients found SMMRT easy to view at home, many patients struggled to return SMMRT through secure messaging to clinicians due to technology-related barriers. Patients who did use SMMRT indicated that it was time-saving and liked that they could review it at their own pace and in the comfort of their own home. Patients reported SMMRT was effective at clarifying issues related to medication directions or dosages and that SMMRT helped remove medications erroneously listed as active in the patient’s electronic health record.

Conclusions

Patients viewed SMMRT utilization as a positive experience and endorsed future use of the tool. Veterans reported SMMRT is an effective tool to aid patients with medication reconciliation. Adoption of SMMRT into regular clinical practice could reduce medication discrepancies while increasing accessibility for patients to help manage their medications.

Prediction of VO2max From Submaximal Exercise Using the Smartphone Application Myworkout GO: Validation Study of a Digital Health Method
Authors: Helgerud Jan , Haglo Håvard , Hoff Jan
Published: August 2022

Background

Physical inactivity remains the largest risk factor for the development of cardiovascular disease worldwide. Wearable devices have become a popular method of measuring activity-based outcomes and facilitating behavior change to increase cardiorespiratory fitness (CRF) or maximal oxygen consumption (VO2max) and reduce weight. However, it is critical to determine their accuracy in measuring these variables.

Objective

This study aimed to determine the accuracy of using a smartphone and the application Myworkout GO for submaximal prediction of VO2max.

Methods

Participants included 162 healthy volunteers: 58 women and 104 men (17-73 years old). The study consisted of 3 experimental tests randomized to 3 separate days. One-day VO2max was assessed with Metamax II, with the participant walking or running on the treadmill. On the 2 other days, the application Myworkout GO used standardized high aerobic intensity interval training (HIIT) on the treadmill to predict VO2max.

Results

There were no significant differences between directly measured VO2max (mean 49, SD 14 mL/kg/min) compared with the VO2max predicted by Myworkout GO (mean 50, SD 14 mL/kg/min). The direct and predicted VO2max values were highly correlated, with an R2 of 0.97 (P<.001) and standard error of the estimate (SEE) of 2.2 mL/kg/min, with no sex differences.

Conclusions

Myworkout GO accurately calculated VO2max, with an SEE of 4.5% in the total group. The submaximal HIIT session (4 x 4 minutes) incorporated in the application was tolerated well by the participants. We present health care providers and their patients with a more accurate and practical version of health risk estimation. This might increase physical activity and improve exercise habits in the general population.
Online forum for testosterone-related discussions may help guide educational initiatives from healthcare providers (Preprint)
Authors: Ashton Leah , Pearlman Amy , Louters Marne
Published: August 2022

BACKGROUND

Testosterone Replacement Therapy (TRT) has been growing in popularity with a 400% increase in use between 2003 and 2013 in men 15 – 45 years of age with subsequent doubling of TRT spending to $2 billion. Rapid increases in TRT use, coupled with barriers to care, likely contribute to use of online communities for discussion among those with common interests regardless of geographic location, social status, or time constraints. Such communities allow for anonymous inquiry through patient-controlled narrative that provides catharsis, validation, and peer support without being subjected to the high financial and time cost of hospitals or clinics.

OBJECTIVE

We aimed to characterize the most commonly asked questions in the r/Testosterone Reddit community to help guide healthcare provider educational initiatives.

METHODS

Publicly-available online Reddit community r/Testosterone posts were reviewed over two eight-day periods in February and October 2021. Content was classified into the following categories: side effects of testosterone, lifestyle and lifestyle changes, bloodwork, TRT protocols, supplemental therapy, over-the-counter (OTC) supplements, injection technique and site, and clinic/online services to obtain TRT.

RESULTS

The first data collection reviewed 277 questions with the most common questions categorized into requests to review bloodwork (50/227, 18.1%), inquiries about supplemental testosterone therapy options (41/227, 14.8%), and questions regarding TRT protocols (28/227, 10.1%). The second data collection reviewed 380 questions. Categorization of the most common questions were review of blood work (77/380, 20.3%) and TRT protocol (48/380, 12.6%). Questions regarding side effects were also commonly asked (and within the top three categories; 58/380 and 15.3%). New, unique questions posed included clinic or online service to obtain TRT and syringes (17/380, 4.5%) and inquiries about injection technique (14/380, 3.7%) and the injection site (9/380, 2.4%). There was a 1.7-fold participation increase from 227 to 380 questions between the two data collections, and over the course of the study, r/Testosterone membership increased from approximately 52,800 to over 73,000. TRT protocols and bloodwork review remained amongst the top three categories discussed between both data collections, whereas the first data set had more questions regarding supplemental therapies and the second data set had more emphasis on side effects of TRT therapy.

CONCLUSIONS

Review of publicly-available online content specific to testosterone offers insight into relevant questions and concerns. Inquiries change over time, and therefore, we must evolve with our patient population. Use of online forums can guide the creation of relevant educational content.

Pengaruh Citra Tubuh terhadap Budaya Konsumsi pada Perempuan
Authors: Nafi Ibdiyana Musyarrifani
Published: August 2022

Women view their bodies more negatively than men and this affects their body image. Body image is a person's evaluation of his physical appearance, other people's perceptions of his body, and how his body is adapted to these perceptions. This paper will focus on discussing the arguments about how women's body image affects their consumption culture. The research method used is literature study of secondary data from book sources, online journal articles, and data published on the internet. It was found that the construction of the ideal body in society was shaped by the capitalist popular culture industry and supported by the mass media. This construction creates a standardization of the definition of ideal beauty. Not only that, the patriarchal culture that places women as symbols of beauty that fulfills aesthetic functions in the household also influences their consumption culture. In addition to being the market object of capitalism's products, women are also the main consumers of products that are believed to help increase satisfaction with their body image, such as beauty, fitness, health, and fashion products.

En el presente trabajo se realizó una búsqueda bibliográfica sobre la presencia de las benzodiacepinas en las aguas residuales y potables, debido a la ineficiencia de las plantas de tratamiento de residuales líquidos, y sus posibles incidencias en los organismos acuáticos. Por otra parte, se estudió el empleo de tres procesos avanzados de oxidación (PAOs) (radiación UV, ultrasonido de alta frecuencia y la radiación gamma) y su combinación con los agentes oxidantes H2O2 y el reactivo de Fenton para la degradación de los fármacos de tipo benzodiacepínico, haciendo un especial énfasis en el diazepam y el midazolam. Se reportaron niveles de notificación en los cuerpos de agua desde 9,5 ng L-1 hasta 1 μg L-1. De los PAO estudiados, el más empleado fue la radiación UV, con un 90-100 % de degradación a las dos horas de tratamiento. El ultrasonido de alta frecuencia fue el proceso menos empleado en la degradación de las benzodiacepinas. En el caso de la radiación gamma, a pesar de sus elevados porcentajes de degradación a dosis entre 2500 Gy y 5000 Gy, el uso de este proceso ha sido limitado por las regulaciones que implican. Para los tres PAOs en estudio, su combinación con los agentes oxidantes H2O2 y el reactivo de Fenton supuso una mejora significativa en la eficiencia de degradación para los fármacos pertenecientes a la familia de las benzodiacepinas.

Aflatoxin-B1 (AFB1) is a common contaminant for staple foods during the storage process. Chronic exposure to AFB1 is widely known to induce the development of hepatocellular carcinoma (HCC). However, there is a lack of understanding of AFBi role in HCC mechanism. This research aims to identify protein(s) in HCC that might interact with AFB1 and to predict the pathway effected by AFB1. Analyses were performed using bioinformatics tools. SMILES notation of AFB1 was submitted into Swiss Target Prediction. Interaction among predicted proteins were analyzed by using STRING. The 3D structure of target protein was constructed by homology modeling. Reverse docking was performed, and the result was ranked based on binding affinity score. Furthermore, protein interaction network was constructed and analyzed by using Cytoscape. Results showed that three protein groups were predicted as target of AFB1, such as kinases, phosphatases, and G protein-coupled receptor with probability of 46.7%, 20%, and 6.7%, respectively. Seven proteins of kinases were strongly related to HCC, including RAF1, MAPK1, MAPK3, AKT1, EGFR, GSK3B, and mTOR. Reverse docking considered the AKT1-AFB1 as the most potential complex with the lowest affinity score -10.2 kcal.mol-1. It has hydrophobic bonds in Trp80, Val270, Tyr272, Asp292, Thr211, Leu210, Leu264, and Lys268 residues, whereas hydrogen bond in Ser205 residues. Moreover, further analysis demonstrated that interaction of AKT1-AFB1 is related to the metastasis pathway in HCC mechanism.

Com a significativa evolução tecnológica vivenciada pela sociedade nos últimos anos, houve uma transmutação de gêneros textuais e, em decorrência, têm surgido novos modos de interação. Assim, com as possibilidades de acesso aos gêneros que circulam em espaços digitais, é fundamental que as escolas insiram em seus currículos propostas de estudos com relação aos textos multimodais, a fim de desenvolver nos alunos a capacidade de ler tais textos e compreendê-los. Nesse viés, o presente artigo busca analisar recursos semióticos constitutivos da videoanimação “Morte e Vida Severina”, embasada no poema do mesmo nome, com vistas a demonstrar as potencialidades que a combinação de semioses pode trazer para o processo de produção de sentidos. A pesquisa parte de uma metodologia bibliográfica que busca compilar estudos acerca da teoria da Semiótica Social (KRESS; VAN LEEUWEN, 2006; HODGE; KRESS, 1988; HOLANDA, 2013; GUALBERTO; SANTOS, 2019) e sobre o gênero videoanimação (ALVES; BATTAIOLA; CEZAROTTO, 2016; ALMEIDA; ALMEIDA, 1998; STEIN, 2000; VILLARTA-NEDER; FERREIRA, 2019). A análise compreendeu uma seleção de excertos do poema e de cenas da videoanimação correspondentes a cada excerto, para que se pudesse comparar os modos de representação na produção escrita e na configuração audiovisual. Como resultado, verificou-se que a videoanimação analisada apresenta potencialidades para o aperfeiçoamento de habilidades de leitura por parte dos estudantes, uma vez que os recursos semióticos usados na animação contemplam dimensões linguísticas e discursivas que mobilizam conhecimentos culturais, incitam a curiosidade e a percepção, estimulam o envolvimento emocional e a criticidade.

Dengue Hemorrhagic Fever is a serious problem in Central Java with an Incidence Rate (IR) of 10.2/100,000 population in 2018. Efforts to reduce the number of dengue fever cannot be separated from efforts to control the Aedes aegypti vector. Alternative vector control that is safer and more environmentally friendly can be done by utilizing compounds derived from plants that have biologically active properties. The plant that has the potential to be developed as a natural insecticide is galangal (Alpinia galanga). The amis of this study was to determine the effectiveness of a water filter added with biolarvicides from galangal rhizome extract. The research method used was a quasi-experimental method with 4 different concentrations of galangal extract (0.1%; 0.2%; 0.3% and 0.4%) and used a negative control without the addition of galangal extract. The results showed that in water filter treatment with galangal rhizome extract, there was death in Ae. aegypti mosquito larvae, while in negative control there was no larval death. The results showed that mortality of Ae. aegypti mostly occurred at a concentration of 0.4% as many as 25 larvae. Water filter with galangal rhizome extract biolarvicide has the potential to kill Ae. aegypti larvae.

Dengue has spread to over 400 of Indonesia’s 497 districts, including West Java Province in which 26 of its districts have been declared as hyper-endemic. A study was conducted to describe the spread of dengue incidences and its cluster during 2008-2017 in Kuningan District. The district is located in an important route, in migration and in the economic field, connecting the northern part of West Java to the southern part. A spatio-temporal analysis based on monthly dengue incidences from the local District Health Office was performed using SaTScan™. This study revealed there were Statistically significant high-risk dengue clusters with various RR in half of the subdistricts in Kuningan in the ten-year periods of 2008-2017 and a retrospective space-time analysis detected 17 significant clusters (P<0.001). Subdistrict Kuningan is detected as a high-risk area every year except for 2008, whereas Jalaksana emerged as a high-risk cluster in six of ten-year periods. We conclude that there was a dynamic spread of dengue cases initiated from the north part of Kuningan District to western areas. This study results do not properly predict RR due to a lack of information on some significant factors, such as vector density and related environmental and socioeconomic parameters. However, this study has provided a perspective on dengue incidence that can be used by local health managers and disease surveillance personnel to monitor prospective outbreaks and make decisions about how to implement an effective response.

N',N'-diethyl-m-toluamide (DEET) is the repellent most commonly used against mosquito vectors of diseases such as dengue, yellow fever and chikungunya. In Brazil, DEET is marketed in aerosol, solution, lotion and gel forms, at concentrations ranging from 6.65 to 25%. In this study, the kinetic degradation under UVC radiation was studied, as well as the penetration/permeation and the ocular irritant potential of DEET repellents in the form of solution, lotion and gel. The photostability study was conducted over 96h, and the DEET degradation kinetics under UVC radiation was fitted to the zero-order model for the three formulations; t90% values of 23.7 h, 17.0 h and 16.1 h were obtained for gel, lotion and solution forms, respectively. The in vitro skin penetration/permeation using the vertical Franz cell in pig skin showed that all the formulations penetrated/permeated the skin layers, at a higher rate when the lotion (p<0.05) was used, possibly due to its qualitative composition. The in vitro ocular irritant potential using the HET-CAM method indicated that one of the products evaluated was classified as "moderate irritant" and five as "severe irritant”. The set of data indicated the lower penetration/permeation of the solution form and reinforces the importance of being careful during application, to avoid accidental contact with the eyes.
