Published: March 2020

Bu çalışmanın amacı Telford, Salmon, Jolley ve Crawford tarafından 2004 yılında geliştirilen Çocuklar İçin Serbest Zaman Aktivite Anketi'nin (Children’s Leisure Activities Study Survey) Türk kültürüne uyarlanması, geçerlik ve güvenirliğinin saptanmasıdır. 2017-2018 eğitim-öğretim yılında Ankara ilindeki ortaokullara devam eden ve yaşları 11 ile 14 arasında değişen toplam 405 öğrenci çalışmaya katılmayı gönüllü olarak kabul etmiştir. Anketin uyarlanması süreci iki aşamadan oluşmaktadır. Birinci aşamada İngilizceden Türkçeye çevrilmesi ve Türkçeden İngilizceye geri çevrilmesidir. İkinci aşamada ise Türkçe ifadelerin anlaşılırlığının test edilmesi için pilot uygulama gerçekleştirilmiştir. Sonrasında geçerlik çalışması için 104 öğrenciye bir haftalık fiziksel aktivite günlüğü dağıtılmıştır. Yedinci günün sonunda günlük formu öğrencilerden geri toplanmış ve Çocuklar İçin Serbest Zaman Aktivite Anketi aynı gün uygulanmıştır. Güvenirlik çalışması için 301 öğrenciye bir hafta arayla iki kez anket uygulanmıştır. Uyum geçerliğinin belirlenmesi için sınıf içi korelasyon katsayıları hesaplanmış ve anketin orta şiddetli, yüksek şiddetli ve orta-yüksek şiddetli fiziksel aktiviteleri içeren aktif bölümünün geçerli (SKK=0.50 ile 0.95 arasında; p<0.05) olduğu ancak düşük şiddetli aktiviteleri içeren inaktif bölümünün geçerli olmadığı (p>0.05) saptanmıştır. Güvenirlik analizleri sonucunda ise sınıf içi korelasyon katsayılarının farklı şiddetteki aktivite türlerinde tüm yaş düzeyleri için (11-14 yaş) 0.52 ila 0.91 arasında değiştiği görülmüştür. Sonuç olarak; Çocuklar İçin Serbest Zaman Aktivite Anketi (ÇSZAA)’nin 11-14 yaşları arasındaki çocuklarda düşük şiddetli (inaktif) aktivitelerin değerlendirilmesinde kullanılamayacağı ancak orta şiddetli, yüksek şiddetli ve orta-yüksek şiddetli fiziksel aktivitelerin değerlendirilmesinde hem geçerli hem de güvenilir bir anket olması nedeniyle 11-14 yaşları arasındaki çocuklarda kullanılabileceği belirlenmiştir.
Mapping Platform Urbanism: Charting the Nuance of the Platform Pivot
Authors: Lee Ashlin , Mackenzie Adrian , J. D. Smith Gavin , Box Paul
Published: March 2020

Urban planners are increasingly working with ideas around datafied cities, such as platform urbanism, to understand urban life and changes with technology. This article seeks to assist urban planners in these efforts by analysing and mapping the qualities of platform urbanism. Drawing on a dataset of approximately 100 examples that detail urban data practices, we trace some of the current tendencies that are shaping the nature and dynamics of platform urbanism. While we identify no unifying narrative or overarching pattern to our data, we interpret this as supporting Barns’ (2019) notion of a pivot towards platforms. We argue this through exploring the interoperability between data sources and domains (vertical and horizontal integration), identifying elements of how platforms intermediate urban life through their growth in different sectors and the use of geolocation, and note the different artefacts that contribute to platform urbanism. We also note a concerning dynamic where city administration becomes ‘locked in’ to specific corporate products and interests, and thereby ‘locked out’ from alternatives. We discuss this in the context of social inclusion and what this means for urban planners, including the fragility of corporate platforms and what platforms urbanism means for social relationships in the city.

Published: March 2020

O objetivo do estudo foi o desenvolvimento e avaliação de um protótipo capaz de auxiliar na amostragem do percevejo marrom da soja, Euschistus heros (Fabricius, 1758), quando submetido à rápida mudança de temperatura, através de um jato de ar quente. Procurou-se conhecer a eficiência do equipamento quanto ao desprendimento e queda dos insetos de suas superfícies de repouso quando submetidos ao aumento de temperatura, através do lançamento de um jato de ar quente. Elaborou-se um equipamento capaz de aquecer o ar de 24 °C, inicialmente, para 50 °C, submetendo os insetos a uma variação térmica de 26 °C por um período de 2 segundos. Para estimativa da eficiência do equipamento, foram utilizados percevejos do primeiro ao quinto ínstar, adultos criados em cativeiro, e adultos capturados em plantações de soja. Estes foram posicionados em frente ao soprador com fluxo de ar de 4 m.s-1 e umidade relativa de 55%. Ao receber o fluxo de ar quente os percevejos desprenderam-se das vagens em uma eficiência média de 86,78% com desvio padrão de 6,96%. Concluiu-se que o equipamento desenvolvido é capaz de derrubar percevejos de todas as fases de desenvolvimento com uma eficiência média de 86,78%, possibilitando a estimativa da população dos insetos na lavoura quando coletados após derrubada.

Published: March 2020

O emprego da mecanização na cafeicultura brasileira é essencial para otimização da produção, entretanto, a crescente exigência dos mercados internacionais em busca de uma cadeia produtiva de baixo carbono faz com que as propriedades cafeeiras busquem compreender como suas atividades contribuem para a emissão de gases de efeito estufa (GEE). O objetivo do presente estudo foi estimar a emissão de CO2 equivalente (CO2 eq) por hectare, nas principais operações mecanizadas realizadas na cultura do cafeeiro no Sul de Minas Gerais. A estimativa de CO2 eq foi realizada através de um estudo de caso, utilizando-se para os cálculos os parâmetros de emissão de GEE da metodologia do GHG Protocol Agricultura. Os resultados mostraram que nas operações de plantio de café em sistema agrícola convencional as atividades de aração, aplicação de matéria orgânica e de bater covas contribuíram com 73,92% das emissões estimadas de CO2 eq ha-1 nesta etapa, totalizando 178,61 kg CO2 eq ha-1. Nos tratos culturais as operações realizadas para colheita mecanizada apresentaram-se como as maiores fontes de emissão de GEE, estimadas em 123,81 kg CO2 eq ha-1.

Published: March 2020

A alelopatia é uma estratégia da planta para sua defesa e delimitação territorial, muito comum em plantas daninhas. O gervão (Stachytarpheta cayennensis) é uma espécie de planta daninha frequente em áreas de cultivo e urbanas na região amazônica do Brasil. Poucos trabalhos sobre alelopatia têm destacado as alterações anatômicas que os metabólitos secundários causam nas plantas afetadas. O objetivo desse trabalho foi analisar a ação alelopática de cinco concentrações de extrato alcoólico (0; 0,5; 1; 2; e 4%) de S. cayennensis a nível de alterações anatômicas em plântulas de Cucumis sativus. Os resultados evidenciaram aumento de espessura nas estruturas anatômicas dos órgãos analisados de pepino em extratos aquosos e alcoólicos, demonstrando acentuado espessamento conforme o aumento das concentrações dos extratos da espécie em estudo. A confirmação de que a liberação dessas substâncias intervêm no desenvolvimento de C. sativus serve como importantes informações a serem utilizadas no desenvolvimento de estratégias alternativas ao uso de herbicidas em outras culturas, visando o manejo ecológico de plantas daninhas.
Hacia el “poeta-camaleón”: pretensiones de impersonalidad en las autopoéticas ensayísticas de Valente
Authors: Lucifora Maria Clara
Published: March 2020

Resumen: En las autopoéticas ensayísticas, los escritores ponen de manifiesto su ideología artística al tiempo que construyen una autofiguración que pretende guiar el derrotero de las interpretaciones de su obra y de su inserción en el campo artístico e intelectual. Este trabajo se centra en un corpus de ensayos eminentemente autopoéticos de José Ángel Valente, escritos a partir de 1970, para explorar la construcción de un sujeto ensayístico siempre en fuga, un «poeta-camaleón» (en palabras de Keats) signado por el intento persistente de alcanzar la impersonalidad, para dejar que la verdad del mundo fluya a través de él. Sin embargo, la figura de autor de Valente es tan potente en el campo artístico que ese intento se frustra y la pretensión de auto-extinción se convierte en un ejercicio discursivo, índice de una posición ética irrenunciable.Palabras clave: José Ángel Valente; ensayos; poeta-camaleón; impersonalidad. Abstract: In the essay autopoetics, writers highlight their artistic ideology, and at the same time, they build an autofiguration that aims to guide the interpretations of his work and its inclusion in the artistic and intellectual field. This paper focuses on a corpus of essays eminently autopoetic of José Ángel Valente, written since 1970, to explore the construction of an essay subject always in flight, a «camelion-Poet» (in Keats’ words), marked by the persistent attempt to reach impersonality, to let the truth of the world flow through him. However, the figure of Valente as an author is so powerful in the artistic field that this attempt is thwarted. Thus self-extinguishing intention becomes a discursive exercise, and index of an unwavering ethical position. Key words: José Ángel Valente; essays; camelion-Poet; impersonality.
Bearings-Only Tracking of Manoeuvring Targets Using Multiple Model Variable Rate Particle Filter with Differential Evolution
Authors: Saeidi Ghasem , Moniri M. R.
Published: March 2020

In standard target tracking, algorithms assume synchronous and identical sampling rate for measurement and state processes. Contrary to these methods particle filter is proposed with variable rate. These filters use a restricted number of states, and a Gamma distribution is applied at state arrival time so that the maneuvering targets could be tracked. Although this structure is capable of tracking a wide range of targets motion features using linear, curvilinear motion dynamics, it suffers from a basic weak point. It cannot estimate the position of targets in high maneuvering regions. Thus, multiple model variable rate particle filter (MM-VRPF) is utilized to overcome this shortage using various dynamic models. A weak point of a particle filter is a phenomenon called degeneracy that even exists in MM-VRPF structure. In this study, differential evolution method, is exploited to improve the mentioned method and a novel structure called multiple model variable rate particle filter with differential evolution (MM-VRPF with DE) is introduced. The simulation results of a bearing only tracking achieved from a maneuvering target, revealed that the proposed structure has better performance while it maintains advantages of variable rate structure.

Authors: Verma Piyush , Verma Alka , Agnihotri Anupam
Published: March 2020

India is an important player in the aluminium, especially because of its abundant bauxite reserves and low-cost skilled manpower. The sector has a significant importance in the growth of Indian economy since the aluminium consumption follows GDP growth curve. Indian aluminium sector is observed as one of the energy intensive sectors with ample scope for improvements in energy efficiency as compared to world standards. The aluminium industries are upgrading themselves by adapting state-of-art technologies, which are more energy-efficient and sustainable in a highly competitive market. These initiatives are further accelerated and motivated by an innovative incentivization scheme (called Perform, Achieve and Trade) of Govt. of India. Currently, the first phase (2012-15) is under implementation, and an unexpected movement towards energy efficiency is envisaged as a result that will ultimately lead towards production of low carbon aluminium for the society.

Authors: Evedove André Ulian Dall , Loch Mathias Roberto
Published: March 2020

Se buscó comparar la prevalencia de comportamientos de riesgo para la salud en hombres mayores viudos con las de hombres mayores con pareja, solteros y divorciados/separados, así como la prevalencia de comportamientos de riesgo en hombres mayores viudos según rango de edad, escolaridad y raza/color. Se realizó un estudio transversal con hombres mayores (≥ 60 años) entrevistados por el Sistema de Vigilancia de Factores de Riesgo y Protección para Enfermedades Crónicas por Encuesta Telefónica (Vigitel) en 2016 (n=5.384) y 2017 (n=5.801) que incluye muestras representativas de adultos de las capitales de los estados brasileños y del Distrito Federal. De ellos, 886 eran viudos. Los comportamientos de riesgo fueron: inactividad física en el tiempo libre, consumo irregular de frutas, verduras y legumbres, tabaquismo y consumo abusivo de alcohol. La prevalencia de tabaquismo fue menor entre los hombres mayores con pareja [RP = 0,68; IC95% (0,52-0,90)] que entre los viudos. En los demás comportamientos de riesgo no se observaron diferencias en la prevalencia de los viudos en relación a los demás grupos. Cuando se analizaron solamente los viudos, se observaron importantes asociaciones de los comportamientos de riesgo con las variables grupo de edad y escolaridad, pero no con raza/color.

Authors: Alqattan Hamad , Morrison Zoe , Cleland Jennifer A.
Published: March 2020

ABSTRACT: This review aimed to identify methodological aspects of qualitative studies conducted to assess patient safety culture (PSC) in hospital settings. Searches of Google Scholar (Google LLC, Menlo Park, California, USA), MEDLINE® (National Library of Medicine, Bethesda, Maryland, USA), EMBASE (Elsevier, Amsterdam, Netherlands), PsycINFO (American Psychological Association, Washington, District of Columbia, USA) and Web of Science (Clarivate Analytics, Philadelphia, Pennsylvania, USA) databases were used to identify qualitative articles published between 2000 and 2017 that focused on PSC. A total of 22 studies were included in this review and analysis of methodological approaches showed that most researchers adopted purposive sampling, individual interviews, inductive content and thematic analysis. PSC was affected by factors related to staffing, communication, nonhuman resources, organisation and patient-related factors. Most studies lacked theoretical frameworks. However, many commonalities were found across studies. Therefore, it is recommended that future studies adopt a mixed methods approach to gain a better understanding of PSC.Keywords: Patient Safety; Culture; Needs Assessment; Qualitative Research.

Levantamento da suscetibilidade de Escherichia coli em infecções do trato urinário no laboratório São Geraldo em Varginha, Minas Gerais
Authors: Costa Daniela Rodrigues , Da Cunha Luciane Tavares
Published: March 2020

A infecção do trato urinário (ITU) é caracterizada pela invasão dos tecidos e colonização de bactérias do sistema urinário. A colonização das vias urinárias podem ser pelas vias baixas e superiores, que são as cistites e pielonefrites. Podem apresentar sintomas ou ser assintomáticas. Os sintomas comuns são febres, micção frequente, disúria em cistites; calafrios, dor intensa e febre são causadas pela pielonefrite. O objetivo deste trabalho foi analisar em culturas de urinas a prevalência da Escherichia coli e seu perfil de suscetibilidade de pacientes do sexo feminino atendidas pelo laboratório São Geraldo. O estudo foi realizado em um laboratório particular na cidade de Varginha–MG. Foram analisados 880 prontuários de pacientes do sexo feminino com faixa etária de 20 a 75 anos em um período de janeiro a dezembro. Dos prontuários analisados 272 foram culturas positivas representando 31%. A média das idades foi de 47,71 anos com desvio padrão de 15,92. As pacientes com idades entre 61 a 75 anos (30%) foram as que mais apresentaram ITU, e depois paciente com faixa etária entre 20 a 30 anos (20%). O micro-organismo mais prevalente foi a Escherichia coli com 87,5%. A Escherichia coli apresentou maior resistência aos antimicrobianos ciprofloxacina, levofloxacina e norfloxacina com pouco mais de 80%. Conclui-se que é importante o uso controlado de antibióticos, pois a resistência microbiana é cada vez maior e, como consequência, dificulta o tratamento das infecções do sistema urinário pelos profissionais de saúde.
Construção de um equipamento de baixo custo para registro de biopotenciais cardíacos visando à análise da variabilidade da frequência cardíaca
Authors: Teixeira Aurélio De Brito , Pereira Rafael
Published: March 2020

Os registros dos potenciais bioelétricos do coração são datados há mais de um século, e atualmente são utilizados tanto no contexto da clínica para instituição de diagnósticos, quanto para ensino e pesquisa nas áreas das ciências médicas. O objetivo desse estudo foi construir um equipamento de baixo custo, capaz de registrar e salvar em computador os dados de biopotenciais cardíacos para análise da variabilidade da frequência cardíaca (VFC), com possibilidade de registro com taxa de amostragem de 250 Hz a 2500Hz, o que viabilizaria o uso para fins didáticos e de pesquisa científica dos biopotenciais cardíacos, de humanos e de animais, por um mesmo equipamento de forma não invasiva. O equipamento proposto foi desenvolvido inicialmente em uma placa de prototipação universal a qual abarcou o sistema de aquisição, filtros e amplificação dos sinais bioelétricos do coração, que foram observados em um osciloscópio digital. A posteriori, foi desenvolvida uma versão final do protótipo como uma interface de ligação feita entre a placa do sistema e o computador através da placa e plataforma de software e hardware Arduino®, onde foi possível salvar os dados e realizar as análises dos biopotenciais, inclusive da variabilidade da frequência cardíaca, com software Origin® e Kubios HRV®. Os registros realizados com as taxas de amostragem propostas mostraram boa resolução temporal e viabilizaram a análise da VFC com boa coerência. Espera-se que o equipamento possa ser utilizado como facilitador em estudos que necessitem a captação de biopotenciais do coração em humanos e animais.

Processos de modificação corporal, como tatuagem, envolvem procedimentos traumáticos ao indivíduo, sendo a porta de entrada para microrganismos oportunistas. Assim, este estudo teve como propósito coletar e identificar fungos presentes em estúdios de modificação corporal. Para tanto, foram coletadas amostras do ar e materiais para tatuar, em três estúdios aleatórios de Maringá-PR. Todas as coletas foram semeadas em placas contendo Sabouraud Dextrose Agar e incubadas a 25 ºC por três dias. De todos as coletas, o desenvolvimento fúngico ocorreu apenas nas amostras de ar, identificadas como: Penicillium sp., Pseudallescheria sp. e Cladosporium sp. no primeiro estúdio; Cladosporium spp. no segundo estúdio; e Fonsecaea spp. e Nigrospora sp. no terceiro estúdio. É importante ressaltar que este é o primeiro trabalho a relacionar a presença de fungos em estúdios de modificação corporal. Conclui-se que houve crescimento de fungos com potencial patogênico nesses ambientes, os quais estão relacionados principalmente a micoses subcutâneas.

Published: March 2020

A intoxicação por carambola (Averrhoa carambola) é frequentemente relatada na literatura humana, porém raramente descrita na veterinária. Desta forma, objetivou-se relatar dois casos de intoxicação alimentar por carambola em cães. Um casal de cães da raça Shih tzu, ambos com dois anos de idade, foram atendidos após a ingestão da fruta carambola, oferecida pelo proprietário. Durante o exame físico, foi observado em ambos os animais taquicardia e taquipnéia, com midríase, apatia, fraqueza muscular, e sonolência, porém responsivos a estímulos sonoros e tácteis, e impossibilidade de manter-se em estação, assim como sucessivos soluços observados. Os animais foram relatados saudáveis e sem condição prévia que justificasse os sinais clínicos descritos. Após a instauração do tratamento suporte com fluidoterapia Ringer Lactato, carvão ativado, Citrato de Maropitant e oxigenioterapia via máscara facial para ambos os cães, os animais apresentaram significativa melhora. Permaneceram por 24 horas em observação na internação, não sendo descritos recidivas dos sinais clínicos pós-tratamento.

Published: March 2020

Herein, we report a case of appendix adenocarcinoma who presented with a recurrence 8 years after the initial diagnosis. A 54-year-old male underwent appendectomy in 2009. The pathology revealed a 1.7 cm diameter low grade mucinous carcinoid tumor. Any additional treatment was not recommended for patient other than appendectomy. The patient was admitted with the symptoms of ileus at 8 years after surgery and then underwent to right hemicolectomy in 2017. On histopathological examination of the specimen revealed a Goblet cell adenocarcinoid tumor, arising from iliocecal valv with pericolorectal tissue invasion of 5 cm in diameter. Lymph-node metastases were found in 16 dissected lymph nodes. The patient was initiated to treat with combined capecitabine and oxaliplatin chemotherapy. There is no clear evidence to support the superiority of any particular chemotherapy regimen for adjuvant treatment of appendix tumors. In this regard more studies are needed to use combined regimens.

Economic Performances of German Agri-Food Businesses: an Extension of Existing Discourses on the Topic
Authors: Berendes Vincent , Blizkovsky Petr
Published: March 2020

Considering the circumstance that literature dealing with the economic performance of agri-food businesses in general, or particularly with the German agricultural sector, mainly deals with strictly agricultural-related theory in order to explain the economic success of agri-food businesses, the present paper aims to extend existing discourses to further areas of thought. Consequently, the characteristics: a) increased size of agribusiness, b) pull-strategies, c) the development of new markets and d) focus on the processing industry, that all correspond to the current picture of the German agricultural sector and are considered to be significantly responsible for recently managing to outpace the French agri-food sector, will be first explained in their success against the background of mainly non-agricultural-related literature. By doing so helpful and rather unnoted perspectives can be contributed to existing discourses. Second, the paper presents scatter plots which portray correlations between a) the added value of agriculture and the regular labor force, b) the added value of agriculture and the number of agricultural holdings and c) the added value of agriculture and the number of enterprises concerning milk consumption. Corresponding scatter plots which show different developments in Germany and France can be related to the findings of the first part of the paper and allow new perspectives in existing discourses as well.

Published: March 2020

[English]: The purpose of this qualitative exploratory study was to analyze students’ gestures in understanding algebraic expression. It involved 59 7th-grade students in Semarang city, Indonesia. Students’ gestures were identified through interviews and observations, then analyzed in three stages: data condensation, data display, and drawing and verifying conclusion. Time triangulation was utilized to assure data validity. The results showed that students employed: (1) direct gestures as a representation of coefficients and variables in the form of hand movements forming the shape of objects that they recognize in the everyday environment, (2) indirect gestures as a representation of coefficients and variables in the form of hand movements as if forming the shape of objects that they recognize in the daily environment then followed by consistent and repetitive hand movements as a representation of the coefficients, (3) direct gesture representing constants in the form of hand movements forming a specific number, and (4) writing gestures and pointing gestures to strengthen the explanation given. The present study concludes that the gestures made by the students in understanding the concepts of algebraic expression consist of representation, pointing, and writing. This study yields an important description of students' gestures and types of gestures about the algebraic concept, which provide a further understanding of the topic.

Connecting university mathematics and school mathematics to address Klein’s double discontinuity: A case of ring theory
Authors: Pramasdyahsari Agnita Siska , Setyawati Rina Dwi , Albab Irkham Ulil
Published: March 2020

[English]: The article aims to reveal how pre-service mathematics teachers (PMTs) identify the connection between ring theory and the mathematics topics in secondary schools in Indonesia. The data was collected from the students' workgroup as a part of course assignments in ring theory course in 6th semester. Through a descriptive qualitative approach, the identified mathematical connections by the PMTs were analyzed through the concept-by-concept framework. The findings show that connection that PMTs made is categorized as concept-by-concept comparison through common features. They could elaborate on the connected topic explicitly at some points and connect the mathematical ideas from ring theory to the school mathematics topics even though they do not reveal all the existing connections.

[English]: Mathematics learning should facilitate students' construction of knowledge. In constructing mathematics knowledge, students involve various types of thinking processes and styles. This qualitative research aimed to describe the process of students’ thinking in identifying concave plane based on Gregorc’s model of thinking style. It involved thirty-three 9th-grade students with a different style of thinking. Data were collected through tests, questionnaire, and non-structured interview then descriptively analyzed to reveal students’ thinking process and styles.  The present study found two different thinking styles, namely Sequential Concrete and Random Abstract from students who successfully identified the concave plane as a kite. There were different thinking processes in the development of definition, opinion, and conclusions from subjects with different thinking styles. However, the difference in the thinking process from each thinking styles do not hamper students’ success in constructing knowledge.

Published: March 2020

Introduction: Uncontrolled pain has many negative effects to the body. The Guideline of Pain Management has been specifically arranged, but assessment and pain treatment in the Emergency Room (ER) have not adequate yet. Integrated pain assessment before and after treatment is very important in monitoring pain management effectiveness. Objective: The aim of this study was to determine pain score of emergency patients before and after treatment. This study was also conducted to record the treatment timing that was given by the paramedics in the emergency room. Method and Material: This study was a description research with 40 trauma patients as samples in the ER at Dr. Soetomo Hospital. Patient’s pain level was measured twice, before the treatment and an hour after that. The pain level was measured using Visual Analog Scale (VAS). Patients were given ketorolac 30mg intravenous as the treatment. Result and Discussion: There were2.5% of the patients VAS 1 and the other 12.5% VAS 10. An hour after treatment 20% of the ER patients were free of pain and the rest 7.5% VAS 6. The average of VAS before the treatment were 6.38 ± 2.1and an hour after later they decreased to 2.23 ± 1.7. There were only 67.5% of the ER patients that were treated in the 1st hour, 17.5% of them were treated in the 2nd hour, the other 10% were treated in the 3rd hour, and the last 5% of them were treated in the 4th hour. Conclusion:The average value of pain was decreased when one hour after administration of pain therapy by paramedics, but therapy at different times showed no difference in the level of pain reduction that can be inferred.

Introduction: Propofol has been known as one out of many inductive drugs which, can cause pain during intravenous injection. There has been a high prevalence of injection pain in pediatric patients. The mechanism of injection pain has not been known. Some therapeutic methods have been tested to reduce the pain, with several success rates. Objective: To compare the effectivity of 5% dextrose-diluted propofol and ringer lactate-diluted propofol, with dilution comparison of 1:1, in their role to reduce intravenous injection pain in pediatric patients, from age 2-15 years old during elective surgery in the Integrated Surgical Building Center of Dr. Soetomo General Hospital Surabaya. Method and Material: Forty-five patients PS ASA I-II, which fulfill inclusion criteria, were induced with general anesthesia. Patients had been selected randomly into three groups. Group I (control group) were injected with propofol without dilution. Group II was injected with propofol with a dilution of 5% dextrose, into 5 mg/ml liquid. Group III was injected with propofol with a dilution of ringer lactate, into 5 mg/ml liquid. Result and Discussion: The level of pain was evaluated afterward, with responding to the four-point scale and spontaneous expression. Patients’ blood pressure, mean arterial pressure, heart rate, and oxygen saturation were also examined after injection. Compared to the control group, those in groups with 5% dextrose-diluted and ringer lactate-diluted propofol are not effective in reducing intravenous injection pain, with analytical statistics p=0.503 (p > 0.05). Also, the dilution of propofol has no significant difference to the hemodynamic measurement of patients. Systolic and diastolic blood pressure, and mean arterial pressure were declined after the induction, but statistically insignificant. The heart rate of patients was inclined but also not significant. Conclusion: 5% dextrose-diluted and ringer lactate-diluted propofol with a comparison of 1:1 were not significantly effective in reducing intravenous injection pain in pediatric patients.
CORRELATION BETWEEN NUTRITIONAL STATUS AND WAIST CIRCUMFERENCE WITH THE INCIDENCE OF HYPERTENSION IN THE ELDERLY

Published: March 2020

Background : Hypertension is the main risk factors of cardiovascular diseases that cause mortality. One of the risk factors of hypertension is obesity. Purpose: This study aimed to determine the relationship between nutritional status and waist circumference with the incidence of hypertension in the elderly. Methods: This study was observational analytic with cross-sectional design. The sample in this study was a partial of the elderly who participated in the elderly posyandu as many as 271 respondents. The sampling techniques is simple random sampling. Secondary data in the form of the results of the elderly health checkup at the elderly posyandu in the Puskesmas Sidotopo Wetan in 2018. Results: This study showed that of 271 respondents, there were 107 respondents found with hypertension (39.50%). The majority of hypertension was suffered by respondents with overweight nutritional status (46.70%), and waist circumference with the central obesity category (74.80%). Correlation found between nutritional status and the incidence of hypertension in the elderly (p=0.02<α=0.05). Prevalence Ratio of 1.32 means that elderly people with overweight nutritional status have the risk of 1.32 times greater to experience hypertension than elderly with underweight and normal nutritional status (p=0.02; PR=1.32). No correlation found between waist circumference and the incidence of hypertension (p=0.21). Conclusion: Nutritional status significantly associated with the incidence of hypertension in the elderly. However, waist circumference is not significantly associated with the incidence of hypertension.
