Published: April 2018

This article is a synopsis of paper SPE 29455, "Optimum Plunger Lift Operation." by J.O.A. Baruzzi and F.J.S. Alhanati. Petrobras, originally presented at the 1995 SPE Production Operations Symposium, Oklahoma City, OK, April 2-4. Please read the full-length paper for additional detail, illustrations, and references.

Plunger lift is one of the best options for low-productivity, high gas/liquid ratio (GLR) wells. Advantages are zero input energy and efficient removal of paraffin and scale depositions. The main disadvantage is a greater requirement for continuous monitoring.

A well producing by conventional plunger lift (Fig. 1) operates cyclically. During the buildup period, the flowline is kept closed. Liquid accumulates at the bottom of the well, and wellhead pressures continuously increase as gas accumulates in the tubing and annulus. After a set time, the flowline opens and a liquid slug, driven by gas expansion below the plunger, is produced to the surface. The main role of the plunger is to mitigate liquid fallback to the bottom of the well. Several electronic controllers for plunger-lift wells are available on the market. Usually, their logic consists of adjusting the buildup and afterflow times on the basis of the measurement of plunger rise velocity However, this may not always be the best approach.

Good estimates of possible well production rates are very important when considering lift alternatives for a particular well. Several prediction models have been suggested. None, however, accurately account for all the phenomena involved. Points of controversy include liquid accumulation at the bottom of the well during buildup and the flow of fluids around the plunger during slug production.

To study several aspects of plunger-lift operation, a small-scale experimental facility was built and a simple hydrodynamic model was developed. This paper discusses the results obtained, pointing out important factors that have been neglected in the past. An extensive literature review determined that neither the possibility nor the consequences of liquid accumulation in the tubing below the plunger or in the annulus during buildup have been addressed. Afterflow time is also an important parameter for well optimization but has not been considered in the dynamic models developed. This work attempts to clarify some of these points.

Published: April 2018

Climate change affects the Mediterranean region stressing lentil crops during flowering and seed set. Early maturation and drought tolerance are desirable traits in these conditions. Phosphorus (P) is considered to enhance early flowering, maturity and thus yields. Four P rates (0, 30, 60, 90 kg P2O5 ha−1) were applied on four cultivars (Samos, Thessaly, Flip, Ikaria) during two seasons. Growing degree-days (GDD) were calculated for vegetative (V4–5, V7–8) and reproductive stages (R1, R2, R4, R6, R8). At R2 (full bloom) carbon isotope discrimination (Δ) was used to assess water-use efficiency. At R8 (full maturity), the seed weight (SW) was determined by harvest. Cultivars, P and the P × cultivar and P × growth season interactions affected the earliness in reproductive stages; P had no effect on GDD of vegetative stages. Phosphorus both induced earliness (Flip, Thessaly) and delayed maturity (Samos, Ikaria). GDD and SW were negatively correlated for the P × cultivar interaction at R1 (first bloom), R2, R4 (flat pod) and R6 (full pod filling) stages; being the strongest at R1. Negative correlations were evident for the P × growth season interaction at R2, R4 and R6 stages; being the strongest at R4. Cultivars and P did not affect Δ. A proper combination of cultivar and P rate can mitigate lentil yield losses under changing Mediterranean climate.
Incorporating carbon emissions from landfills and wastewater treatment into a household emission inventory for systematically analysing household behaviour
Authors: Jia Junsong , Gong Zhihai , Chen Chundi , Gu Zhongyu , Xie Dongming
Published: April 2018

In this paper, taking Nanchang, China, as an example, we first systematically divided household behaviour into three components: entrance (eight lifestyles), kernel (energy uses and private vehicles) and outlet, which was a concern of few scholars and contained the carbon emissions (CEs) of domestic wastewater treatment and landfills. The CEs of entrance were calculated by consumer lifestyle approach and others by Intergovernmental Panel on Climate Change (IPCC). The results showed all the CEs of entrance, kernel and outlet had increasing trend from 1998 to 2014. They were 172.65 × 104, 22.19 × 104 and 9.18 × 104 t CO2 in 1998 and increased to 283.10 × 104, 78.83 × 104 and 23.03 × 104 t CO2 in 2006 and to 458.43 × 104, 206.82 × 104 and 33.55 × 104 t CO2 in 2014. Their shares were 66%–85%, 11%–30% and 4–6%, respectively. Although the CE shares of wastewater treatment and landfills are currently modest, they will become increasingly greater in the future. Thus, it is significant to construct this new accounting frame, especially for analysing sustainable household consumption behaviour. Finally, some attributes of the new frame are clarified, and related policy implications are put forward.

Published: April 2018

An analytical study was carried out to determine the level of uranium in the soil and rock and associate it with the levels in surface and underground water, which are the main sources of drinking water in Singida Urban District, Tanzania. Fifteen water samples, 12 soil samples and nine rock samples were collected in Singida Urban District in February 2016. Water samples were analysed by the Government Chemist Laboratory Agency using inductively coupled plasma optical emission spectrometry (ICP-OES) (2007) and analyses for soil and rock samples were carried out through total X-ray fluorescence (XL3 ANALYSER) at Sokoine University of Agriculture in the Department of Soil and Geological Sciences. Uranium levels in the soils and rocks samples found ranged from 3.744 to 8.754 mg kg−1, SE ± 0.849 and P-value <0.001 for soil and 20.01–31.57 mg kg−1, SE ± 2.474 and P-value 0.077 for rocks respectively. The levels in soil and rock influences the levels in surface and underground water which were between 0.087 and 1.097 mg L−1 for surface water and <0.01–0.46 mg L−1 for underground water, respectively. Singida Urban District has higher uranium levels in the soil and rock with a consequence of high levels in drinking water sources.

Published: April 2018

Due to stringent local regulations and adverse environmental impacts, Vietnamese coal mining industries are under pressure to reuse the large volume of wastewater they produce. To this end, the aim of this study was to add microfiltration (MF) membranes after the conventional Vietnamese coalmine wastewater treatment systems (coagulation/sedimentation/filtration) to assess the feasibility of effluent reuse. The pilot-scale test was performed at a coalmine plant located in Quang Ninh province, Vietnam. Results indicate that precipitation with slaked lime (Ca(OH)2) and polyaluminum chloride (PACl) followed by sand filtration are important pre-treatment steps, prior to microfiltration. To achieve high Mn removals the sand in the filter had to be replaced by a KMnO4 coated sand. The MF membrane produced a stable and high quality effluent that meets the Vietnamese National Technical Regulations for Drinking Water quality (Fe < 0.5 mg/L, Mn < 0.3 mg/L, hardness <350 mg/L as CaCO3). Complete membrane recovery was achieved by sequential 24 h soakings in NaOCl, citric acid and a surfactant.
Risk Factors Associated With Musculoskeletal Injury: A Prospective Study of British Infantry Recruits
Authors: Sharma Jagannath , Heagerty Robert , Dalal S , Banerjee B , Booker T.
Published: April 2018

Background:

Musculoskeletal Injury (MSKI), a common problem in both military and physically active civilian populations, has been suggested to result from both extrinsic and intrinsic factors.

Objective:

To investigate prospectively whether gait biomechanics, aerobic fitness levels and smoking status as well as entry military selection test variables can be used to predict MSKI development during recruit training.

Methods:

British infantry male recruits (n = 562) were selected for the study. Plantar pressure variables, smoking habit, aerobic fitness as measured by a 1.5 mile run time and initial military selection test (combination of fitness, Trainability score) were collected prior to commencement of infantry recruit training. Injury data were collected during the 26 week training period.

Results:

Incidence rate of MSKI over a 26 week training period was 41.28% (95 % CI: 37.28 - 45.40%). The injured group had a higher medial plantar pressure (p < 0.03), shorter time to peak heel rotation (p < 0.02), current smoking status (p < 0.001) and a slower 1.5 mile run time (p < 0.03). In contrast, there were no significant differences (p > 0.23) in lateral heel pressure, age, weight, height, BMI and military selection test. A logistic regression model predicted MSKI significantly (p= 0.03) with an accuracy of 34.50% of all MSK injury and 76.70% of the non-injured group with an overall accuracy of 69.50%.

Conclusion:

The logistic regression model combining the three risk factors was capable of predicting 34.5% of all MSKI. A specific biomechanical profile, slow 1.5 mile run time and current smoking status were identified as predictors of subsequent MSKI development. The proposed model could include evaluation of other potential risk factors and if validated then further enhance the specificity, sensitivity and applicability.
Step Counts of Middle-Aged and Elderly Adults for 10 Months Before and After the Release of Pokémon GO in Yokohama, Japan (Preprint)
Authors: Hino Kimihiro , Asami Yasushi , Lee Jung Su
Published: April 2018

BACKGROUND

Smartphones have been integrated into our society and are expected to serve as tools to improve health outcomes. In the summer of 2016, Pokémon GO, a location-based augmented reality game for smartphones was released; it attracted attention from the perspective of health, especially with its potential to increase physical activity (PA). A few studies have compared objectively measured step counts before and after the release of the game; however, they were conducted over a short study period and evaluated only young people.

OBJECTIVE

The objective of this study was to confirm whether there was a difference in step counts between middle-aged and elderly players and nonplayers before and after the release of Pokémon GO.

METHODS

A total of 46 players and 184 nonplayers aged ≥40 years were matched for sex, age group, and PA level; they were respondents to a questionnaire randomly sent to citizens who were given free pedometers by Yokohama city. Their play status was identified through the questionnaire. To investigate the change in step counts before and after the release of Pokémon GO according to play status, a 2-way repeated-measures analysis of variance was performed. Step counts 1 month before the release of the game were compared with those 8 months after the release. In addition, subgroup analyses according to sex, age group, PA level, and subjective health status were performed.

RESULTS

The mean ages of players and nonplayers were 56.5 (SD 9.9) years and 57.3 (SD 9.6) years, respectively, and the mean baseline step counts of players and nonplayers were 7641.8 (SD 2754.5) and 7903.3 (SD 2674.7), respectively. There was no significant difference in the age and baseline step counts according to a t test (2-tailed). In the analysis of all samples, the interaction between play status and time effect was significant for 3 of 8 months after release. In the subgroup analyses, the interaction was significant for 3 months in men, 7 months in the 55-64-year-old group, 2 months in workers, 4 months in the active group in PA level, and 2 months in participants with subjectively good health. The interaction was significant for only 1 month, at most, in other subgroups.

CONCLUSIONS

The present study confirmed a difference in step counts between players and nonplayers before and after the release of Pokémon GO. According to our analysis, step counts were higher until 7 months after the release. The player group maintained their step counts in winter, despite the decrease in step counts of nonplayers. In subgroup analyses, players were more likely to be men, aged <55 years, workers, active, and subjectively in good health.
A Remote Collaborative Care Program for Patients with Depression Living in Rural Areas: Open-Label Trial (Preprint)
Authors: Rojas Graciela , Guajardo Viviana , Martínez Pablo , Castro Ariel , Fritsch Rosemarie , Moessner Markus , Bauer Stephanie
Published: April 2018

BACKGROUND

In the treatment of depression, primary care teams have an essential role, but they are most effective when inserted into a collaborative care model for disease management. In rural areas, the shortage of specialized mental health resources may hamper management of depressed patients.

OBJECTIVE

The aim was to test the feasibility, acceptability, and effectiveness of a remote collaborative care program for patients with depression living in rural areas.

METHODS

In a nonrandomized, open-label (blinded outcome assessor), two-arm clinical trial, physicians from 15 rural community hospitals recruited 250 patients aged 18 to 70 years with a major depressive episode (DSM-IV criteria). Patients were assigned to the remote collaborative care program (n=111) or to usual care (n=139). The remote collaborative care program used Web-based shared clinical records between rural primary care teams and a specialized/centralized mental health team, telephone monitoring of patients, and remote supervision by psychiatrists through the Web-based shared clinical records and/or telephone. Depressive symptoms, health-related quality of life, service use, and patient satisfaction were measured 3 and 6 months after baseline assessment.

RESULTS

Six-month follow-up assessments were completed by 84.4% (221/250) of patients. The remote collaborative care program achieved higher user satisfaction (odds ratio [OR] 1.94, 95% CI 1.25-3.00) and better treatment adherence rates (OR 1.81, 95% CI 1.02-3.19) at 6 months compared to usual care. There were no statically significant differences in depressive symptoms between the remote collaborative care program and usual care. Significant differences between groups in favor of remote collaborative care program were observed at 3 months for mental health-related quality of life (beta 3.11, 95% CI 0.19-6.02).

CONCLUSIONS

Higher rates of treatment adherence in the remote collaborative care program suggest that technology-assisted interventions may help rural primary care teams in the management of depressive patients. Future cost-effectiveness studies are needed.

O “novo” ensino médio: apontamentos sobre a retórica da reforma, juventudes e o reforço da dualidade estrutural
Authors: Silveira Éder Da Silva , Ramos Nara Vieira , Vianna Rafael De Brito
Published: April 2018

Neste artigo apresentam-se algumas considerações críticas a respeito da reforma do Ensino Médio anunciada pelo governo Temer, expressa na Lei 13.415/2017. Metodologicamente, o texto resulta de uma abordagem de cunho qualitativo, bibliográfico e reflexivo. Enfatizamos algumas características, conteúdos e contradições dessa reforma a partir da tessitura de apontamentos sobre juventudes e Ensino Médio no Brasil, em particular sobre as propagandas do atual governo veiculadas na grande mídia. O texto denuncia a falácia do discurso da escolha dos jovens em relação aos itinerários formativos e o reforço da dualidade estrutural como efeito objetivo da reforma do Ensino Médio. Sobre esse último aspecto, considerando elementos da história da educação brasileira e das políticas educacionais, percebemos que o “novo” Ensino Médio não apresenta novidades capazes de transformar ou solucionar os problemas historicamente acumulados.
Populismo en el siglo XXI: un análisis comparado entre Asia y América Latina (Tailandia, Corea del Sur, Venezuela y Bolivia)
Authors: Garciamarín Hernández Hugo Antonio
Published: April 2018

Aunque el populismo es un fenómeno ampliamente estudiado por la Ciencia Política, hay pocos trabajos en materia comparada, más allá de Europa y América Latina. Esto ha provocado que se avance poco en el análisis de contextos menos explorados, como los de Asia, y en su contraste con populismos más estudiados, como los de América Latina. Por ello, este trabajo desarrolla una comparación entre populismos de Asia y América Latina a partir de cuatro dimensiones de análisis: la simbólica, la política, la ideológica y la repercusión en la calidad de la democracia. Los resultados demuestran que, aunque ambos populismos son simbólicamente incluyentes, sus repercusiones políticas, su expresión ideológica y sus resultados democráticos son sustancialmente diferentes.
Confianza en el Congreso y opinión pública: el caso mexicano
Authors: Gómez Vilchis Ricardo R.
Published: April 2018

La falta de confianza en las instituciones de la democracia puede provocar que los ciudadanos “apuesten” por un retorno hacia un régimen autoritario. En México, ¿cuánta confianza tiene el ciudadano en el Congreso, comparado con otras instituciones? Y, aún más importante, ¿qué determina la confianza ciudadana en el Congreso? Con una base de datos de Barómetro de las Américas (lapop, 2014) que incluye 1 100 observaciones, este artículo utiliza modelos de mínimos cuadrados ordinarios (MCO) y encuentra que los principales determinantes de la confianza en el Congreso son la actitud del ciudadano hacia la democracia como forma de gobierno y su opinión sobre la corrupción que priva entre los funcionarios públicos.
Venezuela: el ocaso de una democracia
Authors: Romero Carlos A. , Benayas Grecia
Published: April 2018

Este artículo plantea la tesis de que, para su estudio, la actual política exterior venezolana debe relacionarse con dos importantes cambios observados en lo doméstico y en lo internacional, entendidos como driving forces. En primer lugar, la creciente erosión de la democracia y el fortalecimiento de regímenes iliberales en el mundo y, en segundo lugar, la transformación geopolítica del orden internacional. Basándonos en los principios del neorrealismo, la jerarquía y el balance de poder en un sistema internacional donde la  concepción clásica de la soberanía y de la discrecionalidad diplomática están cambiando, se concluye que Venezuela se ha convertido en un interesante caso para conocer más sobre esos procesos.
CORDEL E RELIGIOSIDADE: A FIGURA DO PROTESTANTE NA OBRA DA PRIMEIRA GERAÇÃO DE CORDELISTAS
Authors: Vasconcelos Micheline Reinaux de
Published: April 2018

O artigo aborda a produção de cordel de dois autores da primeira geração, Leandro Gomes de Barros e João Melchiades Ferreira da Silva, entre as décadas de 1890 e 1930, cujos folhetos traziam como tema, entre outros assuntos, discussões entre católicos e protestantes. Os estudos que trataram da penetração protestante no Brasil, do início do Oitocentos à primeira metade do séc. XX, ainda não contemplaram o uso dos cordéis como fontes históricas, que nos permitem uma aproximação da perspectiva, em parte, popular do contato com formas de religiosidade que eram novas para a sociedade brasileira. Pela análise dos folhetos, percebemos uma caracterização específica dos protestantes feita pelos cordelistas, os quais destacavam a rejeição do culto a Maria, aos santos, o uso de imagens (a crucifixo), a polêmica em torno da posse e leitura da Bíblia protestante e a descrição pejorativa dos protestantes.
CARLOS GARDEL COMO PATRIMÔNIO CULTURAL NA ARGENTINA
Authors: Kerber Alessander Mario
Published: April 2018

No presente artigo, analiso as práticas de ativação patrimonial realizadas em Buenos Aires para promover Carlos Gardel como patrimônio imaterial dessa cidade e da nação argentina de 1998 até o final da primeira década do século XXI. Para tanto, utilizo, como fontes, a materialidade resultante dessas ações realizadas pelo governo municipal de Buenos Aires: a legislação estabelecida, as intervenções no bairro do Abasto - especialmente a criação do Museo Casa Carlos Gardel - e as publicações produzidas no intuito de afirmar Gardel como portenho e argentino. Em pesquisa realizada anteriormente, havia demonstrado como Gardel construiu uma versão sobre a identidade nacional argentina em suas músicas, imagem e performances, como o próprio artista frequentemente se apresentou como representante dessa nação e como essa versão teve sucesso entre os seus públicos argentinos (constituindo motivo de disputa com os uruguaios) no período entre 1916 e 1935. No presente artigo, abordando um contexto histórico muito distinto, demonstro como as discussões recentes acerca do patrimônio imaterial trouxeram novamente à tona um nacionalismo argentino verificável nas ações realizadas de promover Gardel como patrimônio argentino e portenho.

Published: April 2018

O artigo investiga, a partir de documentação cartorial e da metodologia da História oral, uma família de descendentes de africanos que, diferentemente da grande maioria, conseguiu manter o sobrenome africano desde fins do século XIX, constituindo-se uma “peculiaridade”. Identidade esta, que também trouxe ao grupo, uma ambiguidade. Para além desta característica ímpar, a documentação investigada bem como as narrativas aponta para um passado onde foram proprietários de terras e de escravo. A escrita deste artigo segue a perspectiva das trajetórias de vida, ou da micro-história, com o objetivo de dar visibilidade a peculiaridade da família de descendentes de africanos, que desde o século XIX, em condições adversas, mantiveram o sobrenome de origem bantu na diáspora.

Published: April 2018

Objectives:

To identify unique characteristics of the craniofacial complex and dental maturity in girls with central precocious puberty (CPP).

Materials and Methods:

This study included 34 Korean girls with idiopathic CPP (mean age, 8.6 ± .5 years) and 28 normal healthy girls of the same chronological age. An initial evaluation of the growth pattern of the craniofacial complex and dental maturity was conducted by analyzing lateral cephalometric and panoramic radiographs.

Results:

The mandibular ramus height (44.4 ± 4.1 mm) and total mandibular length (10.8 ± 4.3 mm) (P = .004 and .021, respectively) were greater and the lower anterior facial height was lesser (63.2 ± 2.4 mm) (P = .040) in the CPP group than in the reference group. In addition, the gonial angle (12.9 ± 6.1°; P = .045) and the mandibular plane angle (34.9 ± 4.8°; P = .012) were smaller in girls with CPP than in normal healthy girls. All the mandibular teeth were more mature in girls with CPP (P < .001). A strong positive correlation was observed between the mandibular tooth formation stages and the presence of CPP in girls (r = .756 to .957; P < .001).

Conclusions:

CPP had an effect on the anteroposterior growth of the mandible in the craniofacial complex and the rotation of the mandibular plane angle. Early maturation of the mandibular teeth was observed in girls with CPP.

The effect of the integration of talking toys on preschoolers’ vocabulary learning in English
Authors: Güngör Burcu
Published: April 2018

Appropriate conditions and suitable materials can inspire young children to learn a new language effortlessly. The present study attempted to investigate the effects of English talking toys as teaching materials on vocabulary learning of very young learners (VYL) based on their gender. The study was conducted at one of the public preschools in Yenimahalle/Ankara with 48 five-year old children from two classes. The first group of students was the experimental group and they were instructed using English talking toys as a teaching material. On the other hand, the other class was the control group and was instructed using flashcards. The target vocabulary for this study, which was incorporated into a Vocabulary Checklist Test, was developed after a close scrutiny of the relevant literature (i.e. vocabulary learning in young learners) and examination of the theme-related curriculum employed in the chosen preschool. To assess preschoolers' learning of target words in English, a new Vocabulary Checklist Test was developed by the researcher. The results of a series of t-tests showed that the class instructed with English talking toys performed better on both receptive and expressive/productive vocabulary. The results also indicated that there was not any significant difference between males and females in terms of the effect of English talking toys on preschool children's vocabulary learning. The findings suggest that English talking toys are not only used for entertainment and recreational purposes, they can also be used as teaching material particularly when it comes to teaching basic English vocabulary. The current study contributed to areas such as early childhood education, foreign/second language learning, foreign language testing and evaluation.
Erken çocuklukta işitme cihazı uygulamaları ve ebeveynler

Published: April 2018

Öz: İşitme kaybına işitme cihazlarıyla müdahaledeki amaç, mümkün olan en erken dönemde ses ve konuşma uyaranına erişimi sağlamaktır. Ancak çocuklarda cihazlandırma, işitme kaybına müdahale için bir başlangıç olarak kabul edilmelidir. İşitme kaybının müdahalesinde kullanılan yardımcı teknolojiler diğer engel türlerinden işitme kaybını ayırmakta, ebeveynlerin müdahale hakkında detaylı bilgilendirmesini zorunlu kılmaktadır. Bu bilgilendirme işitme kaybının doğasını, işitme cihazlarının özelliklerini, kullanım süresini, idamesini ve bakımını kapsamalıdır. İşitme kaybı ve müdahalesine ilişkin yeterli bilgi sağlanmadığında, işitme cihazlarını düzenli kullanılmamakta veya teknik sorunların çözülmesi gecikmektedir. Doğru bir bilgilendirme ebeveynlerin tüm bu zorlukların üstesinden gelmesini sağlayarak, müdahalenin verimliliğini artıracaktır. Bu bağlamda mevcut derlemede çocuklarda işitme cihazı uygulamalarında ebeveynlerin rolleri ve bu rollerin müdahale sürecine getirdiği açılımlar betimlenmiştir. Erken çocukluk döneminde işitme cihazı uygulamalarını ve ebeveynlerin rollerini betimlemeyi amaçlayan derlemede, işitme kaybının müdahale sürecinde ebeveynlerin yaşadıkları sorunlara kavramsal olarak değinilmiş, ebeveynlerin yaşadığı bu sorunları en aza indirebilmek adına yapılacak doğru bir bilgilendirme sürecine yönelik farklı önerilere yer verilmiştir. Bu amaç doğrultusunda yapılanan derleme türü bu çalışmada yazarların erken çocukluk dönemi işitme cihazı uygulamalarına ilişkin klinik deneyimi temelinde alanyazın bilgilerinin sentezi, yorumu ve değerlendirilmesi yapılmıştır.

Bu çalışmada, Kayseri ili merkez ilçelerinde (Melikgazi, Kocasinan, Talas) bulunan altı yaş çocuklarına sunulan yaratıcı sınıf ortamlarının, çocukların yaratıcı düşünme becerileriyle ilişkisinin incelenmesi amaçlanmıştır. Araştırmanın çalışma grubunu, 51 öğretmen ve bu öğretmenlerin sınıflarında bulunan 357 çocuk oluşturmaktadır. Veri toplama aracı olarak öğretmenlere sınıflarındaki yaratıcı ortamı kaydetmeleri için “Okul Öncesi Yaratıcı Sınıf Ortamı Ölçeği” ve çocukların yaratıcılık düzeylerini belirlemek için “Hibrit Yaratıcılık Testi” uygulanmıştır.   Araştırma sonuçları; çocukların yaratıcılıklarının orta düzeyde, öğretmenlerin görüşlerine dayalı olarak sınıf ortamının yaratıcılık düzeyinin ise oldukça yüksek düzeyde olduğunu göstermiştir. Sınıf ortamının yaratıcılık düzeyine ilişkin elde edilen sonucun öğretmenlerin ortamın yaratıcılık düzeyini yapay bir olumlulukla yüksek görmeye eğilimli olmalarından kaynaklandığı söylenebilir. Ayrıca okul öncesi eğitim kurumunda bulunan sınıfların ortamlarının yaratıcılık düzeyi ile çocukların yaratıcılık düzeyi arasında pozitif yönde ancak düşük düzeyde ilişki olduğu tespit edilmiştir. Bu bulgu, öğretmenlerin okul ortamını çocukların ilgi, yetenek, beceri ve gereksinimleri doğrultusunda gerekli yaratıcı özellikler taşıyacak şekilde düzenleyemediklerini ya da çocukların yaratıcılıklarını ortaya koymalarını sağlayacak özellikte etkinlikler organize etmede zorlandıklarını düşündürmüştür.

Erken çocukluk, beynin gelişiminin en yoğun olduğu, bilişsel ve sosyal becerilerin temellerinin atıldığı bir dönemdir. Bu makalede, erken çocukluk döneminde ortaya çıkan becerilerin bağlantılarını ve gelişimlerinde rolü olan unsurları farklı örneklemlerde (tipik ve atipik gelişim gösteren çocuklar, tipik ve atipik gelişimsel bağlamlarda yetişenler) incelediğimiz araştırmalarımızı özetliyor, sonuçlarını diğer literatür bulgularıyla birlikte değerlendiriyoruz. Bulgular iki becerinin, alıcı dil ve yönetici işlev becerilerinin çocuğun psikolojik esenliği ve optimal gelişimi için kritik olduğunu ortaya koyuyor. Bu becerilerin gelişimine hangi unsurların nasıl etki ettiğini gösteren araştırma sonuçlarımızı derliyor, uygulamaya dair önermelerini tartışıyoruz.
Akademisyen olmak

Published: April 2018

Akademisyen olmayı sadece bir meslek olarak göremeyiz. Akademisyen olmayı hayat tarzına dönüştürmüş insanlar başarılı olabilir. Akademisyen olmak, başlıca iki konuda incelenebilir. Akademisyen olacak hocaları yetiştirmek açısından ve akademisyen olmayı seçen genç elemanlar açısından olarak ele alınabilir. Akademisyen olacak hocaları yetiştiren akademisyenler öncelikle objektif bir alım yapmalıdır. Daha sonra, hoca asistanının mesleki gelişimi desteklemeli ve alanda etkin bir konuma getirmelidir. Akademisyen olmayı seçen genç elemanlar ise, alanda deneyimli bir hoca ile çalışarak kendilerini geliştirmelidir. Bunun yanında bilgi birikimlerini artırmalı ve genel kültürlerini geliştirmedirler. Ders verme, araştırma ve yayın konularında kendilerini olabildiğince geliştirmelidirler. Puan kaygısıyla değil; alana katkı yapma kaygısıyla yapmalıdırlar.
Okul öncesi kaynaştırma sınıfında öğretmen
Authors: Metin Nilgün
Published: April 2018

Kaynaştırma programlarının temel amacı, özel gereksinimli çocukların içinde yaşadığı topluma uyum becerileri kazandırmaktır; aynı zamanda bu uygulamaların toplumda farklılıklara saygı ve özel gereksinimli bireylerin sosyal kabulünde artış sağlayacağı da düşünülmektedir. Kaynaştırma programlarının amacına ulaşmasında en etkili kişi olan öğretmenler bu uygulamalarda genel olarak üç önemli sorunla karşılaşmaktadır: Özel gereksinimli çocukla nasıl iletişim kurabilirim; problemlerle nasıl baş edebilirim? Eğitim programını nasıl uyarlayabilirim? Öğretmenler genellikle kaynaştırma programlarına karşı olumsuz tutuma sahiptirler, bunun nedeni ise özel gereksinimli çocuklar ve ihtiyaçları konusunda yeterli bilgiye sahip olmamalarıdır. Kaynaştırma programlarının amacına ulaşabilmesi ve tutumların iyileştirilmesi için öğretmen yetiştirme programlarında ve hizmet içi çalışmalarda, öğretmenleri özel gereksinimli çocuklar ve ihtiyaçları konusunda yeterli düzeyde bilgilendirmenin yanı sıra danışman destekli uygulama çalışmalarına yer verilmelidir.

Authors: Kumaladewi Yuliyana , Fatimah Sari , Nuraeni Aan
Published: April 2018

AbstractBackground: Ventilator associated pneumonia (VAP) has been known to be the most common nosocomial infection in Intensive Care Unit (ICU). VAP increases length of care, cost, morbidity and mortality of patients in ICU. The ICU of RSMH Palembang have already been doing prevention of VAP incidence through VAP bundles, but the number of incidence were still high. Purpose: This study aimed to identify the factors associated with VAP incidence among the patients in ICU RSMH Palembang. Method: this study was quantitative study with kohort prospective approach. Samples were recruited from ICU RSMH Palembang using consecutive sampling technique for 4 months period (n=61). Data were collected using a questionnaire package consisting of a demographic questionnaire, CPIS instrument, APACHE II, an observation sheets that measure duration of using antibiotics, duration of using ventilator, reintubation and hand hygiene compliance. Data were analyzed using descriptive quantitative and logistic regression analysis. Results: VAP occured in 12 patients (19.7%). Bivariate test result with α:5% have shown that APACHE II (p:0.043), duration of using antibiotic (p:0.023), duration of using ventilator (p:0.001) and reintubation p:(0.001) were related to the incidence of VAP. Logistic regression analysis shows that reintubation (OR=0.035; CI 95%:0.28-0.658; p=0.013) and duration of ventilator > 5 days (OR=0.082; CI 95%: 0.09-0.74; p=0.026) were significant factor that affecting VAP. Conclusion. Reintubation was the most related factor with VAP incidence. It is recommended for doctors and nurses to conduct a proper and thorough assessment before extubation to minimalize the risk of reintubation.

AbstractHealth care management has an obligation to always provide safe, sustainable, comprehensive, quality and satisfactory health care for both the service user and care provider. The management and culture are built through the Interprofessional Health Care Collaborative Practice Model (MPIPK), which are implemented through four model components, i.e. the clinical pathway of patient management, team management of patients, patient care integrated documentation, and interdisciplinary patient problem solving through interdisciplinary case conference forums. In order to realize interprofessional collaboration practices, a cohesive climate is required that supports group functions and performances, and an instrument is needed to measure the team cohesiveness of this model. This research was conducted to develop a team cohesiveness measurement instrument in the interprofessional collaboration of health care. The instrumentation research design was carried out through the following steps: 1) Preparations of the instrument design commenced from the synthesis theory related to collective culture and individual culture on four components of the model; 2) Validation of the contents of the instrument with related experts; 3) Construct validation with 237 healthcare practitioners in an accredited hospital setting. Expert judgment results on instrument relevance (CVI) ranged from 0.77 to 0.91, the essence of instrument contents (CVR) was in range (+) 0.27 - 0.63, CVI and CVR scores indicated the relevant and essential content of the instrument. Test results of all constructed items were valid (0.283 - 0.847) and reliable, α Cronbach on 4 components (0.792 - 0.963) so, it is feasible to be used to measure the team cohesiveness.
Ciudadanía sexual en Costa Rica: los actos, las identidades y las relaciones en perspectiva histórica
Authors: Jiménez Bolaños José Daniel
Published: April 2018

Esta investigación tiene dos objetivos principales: sistematizar las discusiones teóricas con respecto al tema de ciudadanía sexual y proponer esta categoría de análisis para el abordaje de diferentes problemáticas asociadas a las políticas de sexualidad e identidad en Costa Rica. Mediante una revisión de fuentes periodísticas y estatales, se abordan diferentes coyunturas, principalmente en la década de 1990. Temas como el matrimonio igualitario y la creciente exposición de la diversidad sexual muestran que la ciudadanía sexual, como variable conceptual, puede ampliar el rango de estudio, al crear un diálogo entre las demandas por derechos, la canalización institucional de dichas demandas y la resolución usualmente insatisfactoria por parte del Estado para acatarlas.

The aim of the study was to determine whether the B-type natriuretic peptide (BNP) plasma level predicted the severity of bronchiolitis without additional pathology in children admitted to an emergency department (ED). A total of 232 children (mean age: 7.7±1.2 months [range: 1-23 months]) presenting to ED with isolated bronchiolitis and 32 age- and gender-matched control subjects were included in the study. BNP levels differed significantly among the control (8.5±1.1 pg/ml) and mild (27.7±2.6 pg/ml), moderate (51.4±0.5 pg/ml), and severe (106.8±4.8 pg/ml) bronchiolitis groups (p < 0.001). Clinical severity score (p < 0.001; OR: 2.524; 95% CI: 1.826-3.487) and plasma BNP level (p < 0.001; OR: 2.231; 95% CI: 1.583-3.242) were independent risk factors for hospitalization. The length of hospital stay was significantly correlated with BNP level (p < 0.001; r: 0.698). In conclusion, the plasma BNP level may be a potent biomarker predicting disease severity in ED.
Rapunzel syndrome in a seven year old female
Authors: Gupta Anand , Kaur Jaswinder , Wadhwa Nishant
Published: April 2018

Rapunzel syndrome is characterized by gastric trichobezoar with extension beyond pylorus. Seven year old female presented with chronic pain abdomen and loss of appetite. Upper gastrointestinal (UGI) endoscopy showed large trichobezoar in the stomach with its tail extending into proximal duodenum. Child underwent exploratory laparotomy and a large trichobezoar measuring 15 cm was removed. Psychiatric opinion revealed that the child was suffering from `trichotillomania`; an obsessive compulsive disorder. UGI endoscopy is the preferred modality for diagnosis, as it delineates the mass and its extent. Small bezoars can be extracted via endoscopy using various disintegrating techniques but large bezoars need surgical management.
RELAÇÃO PROFESSOR-ALUNO: INTERAÇÕES MEDIADAS PELOS RECURSOS TECNOLÓGICOS DE COMUNICAÇÃO
Authors: Buzetto Angela Maria Frias Gonçalez , Fiamenghi-Jr Geraldo Antônio , Silva Marjorie Cristina Rocha
Published: April 2018

O objetivo foi analisar as percepções de aprendizagem dos alunos e as possíveis interferências nas formas de relação professor-aluno mediadas pelos recursos tecnológicos de comunicação. Os dados foram coletados por meio de um questionário em uma Faculdade Particular de São Paulo, em 46 alunos do primeiro ano de um curso superior, de ambos os sexos, entre 19 a 25 anos de idade. A aplicação grupal durou aproximadamente 50 minutos. Segundo a análise de conteúdo, destacaram-se situações em sala de aula cujas relações entre professores e alunos foram essenciais pelo vínculo afetivo estabelecido. Embora os participantes utilizem o celular continuamente, afirmam preferir as conversas ‘cara a cara’, por serem mais pessoais, permitirem perscrutar os estados emocionais e reações do outro, constituírem mais sigilosas e prazerosas. Essa temática é importante, pois as mudanças nas formas de interação demandam um novo olhar para o processo de ensino e aprendizagem.

Socio-semiotics as a journalism research method
Authors: Rodrigo-Alsina Miquel
Published: April 2018

As it will be possible to observe, the confrontation between semiotics and sociology in the study of journalism should take on various shades of meaning. In the first place, it is not pertinent to conceive a field of study as a battlefield in which different disciplines confront each other. On the contrary, there are many points in common between sociology and semiotics. In the second place, we should recall that one of the classic counterviews is that of quantitative content analysis, more characteristic of sociology, versus qualitative semiotics analysis. This confrontation is not new in the social sciences (Alvira, 1983). However, we should point out that we find ourselves facing a false dichotomy. The two methods are not incompatible, but rather complementary.
Journalism and change in the experience of time in Western societies
Authors: Franciscato Carlos
Published: April 2018

The purpose of this paper is to investigate the temporality produced by journalistic practice and the ways journalism has a privilege to build a specific type of social experience of the present time. This inquiry carries out a historical journey, but it is not our purpose to present a history of press in the sense of a history of institutions, particular genres and languages. Instead, this investigation develops a historical study in order to identify social temporal phenomena produced by journalism, and to express them in the form of descriptive categories, which give regularity to a diversity of temporal phenomena: instantaneity, simultaneity, periodicity, novelty, and public disclosure. Besides, we consider this work a theoretical study that uses historical elements to analyze, through a sociological approach, fundamental aspects of a social constitution of journalistic temporality.
Journalism as a research field
Authors: Sodré Muniz
Published: April 2018

This work deals with the emphasizing as necessary of the correlation be­tween journalistic practice and total culture in its mutations stemming from the new information and communication technologies. One of the epistemological preliminary aspects is the critique of the informational conception which conceives communication as the mere transfer of contents from one point to another and which has been sustaining theoretically the majority of media studies.
Can still images tell stories? Symptom and temporality in photojournalism narrative theory
Authors: Casadei Eliza Bachega
Published: April 2018

Temporality is one of the central concepts in defining narrative. In this sense, photojournalism has always been a problem for narratological studies, since traditional image theories understand photography as a figure that immobilizes time. The aim of this paper is to discuss if photojournalistic practice is able to engender narratives or whether it is merely linked to description. Since traditional theories, linked to the realm of visible, expel temporality of photojournalistic narratives, we must to give it back time to the image from another record: the visual. Our argument is that it is in the interchange of visible with the visual that narrative and temporality is given in photojournalism, in an image conception that does not take into account only the semiotic elements of photojournalism, but also its symptomatic aspects.
