Authors: Gupta Shipra , Arora Kirti , Trilok-Kumar Geeta
Published: April 2018

Severe zinc deficiency is rare in India but mild to moderate deficiency could be widespread. There is little data on zinc intakes based on nutritional assessment methods, mainly because the Indian Food Composition Tables that were available until recently gave incomplete zinc content values in foods. A pilot study was, therefore, undertaken to assess the zinc content of cereals and pulses consumed in Delhi and to compare the values with those given in the latest Indian Food Composition Tables. Four hundred and twenty six samples of twenty three varieties of cereals / cereal products and fifteen varieties of pulses, collected from wholesale suppliers in the north, south, east and west zones of Delhi, were analyzed for zinc using atomic absorption spectrophotometer. The concentration of zinc in a given cereal or pulse varied widely between the different zones. Cereals like pearl millet, Italian millet, dry maize, whole wheat and its flour and pulses like roasted Bengal gram and dry peas, Bengal gram dhal and lentil dhal were identified as rich sources of zinc. The mean zinc content in most of the foods analysed in the laboratory showed significant differences when compared with the mean values for cereals and pulses reported in the Indian Food Composition Tables given by the National Institute of Nutrition - Indian Council of Medical Research in 2017. A region specific food composition database is urgently needed as there seem to be huge differences in the zinc values of cereals and pulses consumed in Delhi as compared to the average values representative of all states given in the latest food composition database.

Authors: Johari Aanchal , Kawatra Asha
Published: April 2018

In the present study effect of processing treatments viz. blanching and germination on the proximate composition of Pennisetum glaucum (pearl millet) was studied. Proximate composition was analysed by the standard methods determined according to Association of Official Analytical Chemists. Results indicated that moisture content increased significantly after processing treatments. Blanching resulted in non significant increase in ash content of pearl millet grains. The crude protein content of unprocessed pearl millet was 11.55%. The crude protein content of blanched pearl millet grains was 11.27%. Crude protein content of germinated grains was found to be 12.38% as in comparison to 11.55% in unprocessed and 11.27 in blanching treatment. Crude fat content of unprocessed (control), blanched and germinated pearl millet grains were 5.36, 5.09 and 4.55%, respectively. Fiber content increased significantly after blanching and germination processing treatments. Processing treatments not only effect the nutritional composition of pearl millet but also contribute towards enhancement of shelf life.

Authors: Parekh Hetal N. , Mandalika Subhadra , Mehtalia Suresh
Published: April 2018

Risk of obesity, inflammatory conditions and poor glycemic control have been reported to be lower among vegetarian T2DM patients due to their lower intake of fat, high intake of dietary fiber and micronutrients. However, several factors influence dietary practices and thereby glycemic control among patients which demands in depth observation. A cross-sectional observational study to examine the association between body composition, glycemic control and hs-CRP of Type 2 Diabetes Mellitus (T2DM) patients was conducted on 160 uncontrolled T2DM patients including 81 (50.6%) vegetarians and 79 (49.4%) non-vegetarians with mean age of 49.8±7.2 years. They were assessed for body composition using anthropometry. Biochemical parameters [(Fasting Blood Sugar (FBS), Post Prandial Blood Sugar (PPBS), Glycosylated Hemoglobin (HbA1c) and high sensitive C Reactive Protein (hs-CRP)] were obtained from their case files. Data were analysed using SPSS software for Windows (Version 16.0, 2007, SPSS Inc, Chicago IL). Anthropometric indices (weight, BMI, WC, hip circumference, WHR, BMR, visceral fat) and hs-CRP levels were significantly higher in vegetarians than non-vegetarians (p<0.05). However, there was no significant difference in FBS, PPBS and HbA1C between the two groups (p>0.05). Vegetarian participants had higher hs-CRP (≤3.0 mg/dl) and poor glycemic control. A positive correlation of anthropometry indices with hs-CRP was also observed among the participants (p<0.05). Dietary practices of vegetarians might vary across the populations and communities and hence there is a strong need to strictly consider these differences in the development of dietary strategies for T2DM.

Authors: Parab-Waingankar Prajakta , Rao Shobha
Published: April 2018

The pertinent role of diet in the development of obesity and metabolic syndrome (MS) is evident among studies from developed countries, however scarce data is available from India that has a culturally unique diet pattern. Data on socio-economic background, dietary patterns, BMI, body fat, circumferences, skin folds and blood pressure were recorded on 302 affluent men (30-60 years) in a cross-sectional study in Pune, India. Fasting blood estimations were performed for glucose, insulin and lipids. The subjects were predominantly (70%) vegetarians with daily butter consumption at 50%, high consumption (> 4 times / week) of milk at 60.5% and > 2 times / week for milk products (36%), home-made fried snacks (35%), outside snacks (25.5%) and outside meals (32.2%). High consumption of home-made fried and sweet snacks, outside snacks and milk products showed significantly higher (p once/week) as compared to consumption of once or less per month, even after adjusting for BMI. It was thus evident that consuming foods high in unhealthy fats and sugar (> 2 times/week) increased the risk for both abdominal obesity and metabolic syndrome.

El buen funcionamiento del Hardware y Software de una Cámara Gamma SPECT, depende de la correcta configuración y del control de calidad. Estas acciones son esenciales para la obtención de imágenes clínicamente válidas. Los fabricantes, recomiendan estas acciones, sin embargo, no existen técnicas descritas en los manuales correspondientes a estos equipos. Los objetivos del presente trabajo consisten en proponer una técnica exclusiva para el control de calidad extrínseca de una Cámara Gamma SPECT de fabricación variable que estén reconocidas en NEMA, IEC. Para ello se construye un módulo mezclador automático para preparar fantomas de campo uniforme, mediante el cual nos permitirá realizar los controles de calidad de los equipos SPECT. El módulo está constituido por un equipo mezclador automático y de un maniquí (denominado fantoma). Mediante la homogeneidad de mezclas bifásicas, obtenemos mapas de corrección extrínsecos, las mismas que nos sirven para evaluar la calidad del equipo. Se puede observar que depende de la homogeneidad de la mezcla y su distribución óptima de la mezcla miscible en el fantoma y en cantidades de volúmenes precisos, tales como: Cloruro de sodio 0.9% (3.5 litros) y Pertecnetato de sodio Tc 99m (?20mCi) de 0.1 a 0.4 ml. Considerando además la exposición a la radiación al preparar la mezcla fluida al tratar de conseguir que una pequeña cantidad de Tc‐99m, se concentre adecuadamente por el volumen de agua destilada en el maniquí, en el menor tiempo posible. El rendimiento del módulo mezclador analizado ha sido un trabajo de investigación muy importante, éste depende del diseño apropiado del sistema mezclador (impulsor), conformado por la geometría, el modelo matemático de la mezcla, análisis de la concentración, pruebas (geometría recipiente, volumen, diámetros), velocidad (potencia del motor), forma de las paletas mezcladoras (ángulo y número) componentes muy importantes en los objetivos trazados. La eficacia de la mezcla bifásica se muestra con la adquisición óptima de las imágenes de calidad de la Cámara Gamma SPECT, que actualmente se usan en los centros de Medicina Nuclear, INEN.

Published: April 2018

Las construcciones civiles edificadas sobre suelos inestables son vulnerables a los procesos naturales como la geodinámica interna, externa y el cambio climático. El poblado de Tapacocha que está asentado sobre suelo deslizado es sensible a los procesos naturales. El terremoto de mayo de 1970 ocasionó fracturamiento de la planicie, destrucción de sus construcciones; las intensas lluvias de los años 1942 y 1997 ocasionaron huaycos que destruyeron algunas de sus edificaciones y terrenos de cultivo. La geodinámica interna modeló el basamento con un intenso plegamiento y fracturamiento de las rocas sedimentarias; la geodinámica externa por geoformas modeladas por los movimientos rotacionales, deslizamientos, erosión diferencial. En la actualidad el efecto del cambio climático se manifiestan por las inusuales torrenciales lluvias que erosionan periódicamente y ponen en peligro las edificaciones civiles y la agricultura. Con el presente estudio se propone alertar a las autoridades y sus pobladores para prevenir y mitigar los efectos naturales destructivos.

Estudio palinológico de un perfil sedimentario del Holoceno medio-tardío, oeste del Iberá, Corrientes, Argentina
Authors: Fernandez Pacella Lionel
Published: April 2018

Con la denominación "Iberá", identificamos a uno de los humedales tropicales más importantes de la biósfera en términos de su extensión y de las especies que lo habitan, tanto animales como vegetales. El objetivo de este trabajo es a partir del análisis polínico y litológico de un perfil sedimentario, reconstruir las comunidades vegetales predominantes y sus variaciones, inferir los cambios en las condiciones climáticas que se habrían producido y deducir el ambiente deposicional durante el Holoceno medio y tardío en la región del Iberá. El perfil fue muestreado sobre una barranca ubicada en la zona central de la margen occidental del Sistema Iberá, en la localidad de San Miguel. La dinámica de la vegetación y la relación de los taxones permitieron establecer tres zonas polínicas: La Zona Polínica I (Holoceno medio) presenta una asociación característica de la estepa graminosa. Las litofacies identificadas sugieren un ambiente depositacional de valles anegadizos, que junto a las paleocomunidades vegetales reconocidas, señalarían para el Holoceno medio, condiciones húmedas. Las Zonas Polínicas II y III (Holoceno tardío) registran una asociación característica de estepa herbácea psamófila. El aumento observado en las Brassicaceae, estaría indicando disturbios ambientales, los cuales podrían reflejar la combinación de una intensa acción eólica bajo un clima árido. Las litofacies identificadas señalan un ambiente eólico con derrames fluviales y junto a las comunidades vegetales reconocidas, indicarían para el Holoceno tardío, condiciones áridas a semiáridas.
Caverna del Valle de Los Lisos: una hipótesis sobre su origen en el contexto geomorfológico de las Sierras de Córdoba, Argentina
Authors: García-Aráoz Eduardo
Published: April 2018

La caverna del Valle de Los Lisos conforma el cierre de una cuenca hidrográfica de aproximadamente 133 hectáreas, ubicada en el macizo Los Gigantes del batolito de Achala, en la Provincia de Córdoba, en la parte central de Argentina. Se compone de una serie de intrincados pasadizos desarrollados en litología granítica, con 20 metros de avance horizontal en sentido Norte-Sur y 25 metros de descenso total. Por su nivel inferior circula el arroyo que drena la cuenca. De acuerdo con las observaciones realizadas, se propone un modelo genético-evolutivo de la caverna que es consistente con la evolución geomorfológica regional de las Sierras de Córdoba, y consta de tres etapas luego del emplazamiento del cuerpo intrusivo: 1) Desarrollo de un perfil de meteorización profundo que condiciona la formación de un paleo-relieve con predominio de una morfología abochonada. 2) A partir de un escarpe mixto (erosivo y estructural), la generación de la cuenca hidrográfica que alimenta el cauce que circula a través de la caverna. 3) Formación de las galerías principales en sucesivas fases de erosión.

Authors: Van Hala Sonja , Cochella Susan , Jaggi Rachel , Frost Caren J. , Kiraly Bernadette , Pohl Susan , Gren Lisa
Published: April 2018

Background and Objectives: We sought to develop and validate a self-assessment of foundational leadership skills for early-career physicians.
Methods: We developed a leadership self-assessment from a compilation of materials on health care leadership skills. A sequential exploratory study was conducted using qualitative and quantitative analysis for face, content, and construct validity of the self-assessment. First, two focus groups were conducted with leaders in medicine and family medicine residents, to refine the pilot self-assessment. The self-assessment pilot was then tested with family medicine residents across the country, and the results were quantitatively evaluated with principal component analysis. This data was used to reduce and group the statements into leadership domains for the final self-assessment.
Results: Twenty-two invited family medicine residency programs agreed to distribute the survey. A total of 163 family medicine residents completed the survey, representing 16 to 20 residency programs from 12 states (response rate 28.9% to 34.8%). Analysis showed important differences by residency year, with more advanced residents scoring higher. The analysis reduced the number of items from 33 on the pilot assessment to 21 on the final assessment, which the authors titled the Foundational Healthcare Leadership Self-assessment (FHLS). The 21 items were grouped into five leadership domains: accountability, collaboration, communication, team management, and self-management.
Conclusions: The FHLS is a validated 21-item self-assessment of foundational leadership skills for early career physicians. It takes less than 5 minutes to complete, and quantifies skill within five domains of foundational leadership. The FHLS is a first step in developing educational and evaluative assessments for training medical residents as clinician leaders.

Authors: Binczyk Natalia M. , Babenko Oksana , Schipper Shirley , Ross Shelley
Published: April 2018

Background and Objectives: Residents in difficulty are costly to programs in both time and resources, and encountering difficulty can be emotionally harmful to residents. Approximately 10% of residents will encounter difficulty at some point in training. While there have been several studies looking at common factors among residents who encounter difficulty, some of the findings are inconsistent. The objective of this study was to determine whether there are common factors among the residents who encounter difficulty during training in a large Canadian family medicine residency program.
Methods: Secondary data analysis was performed on archived resident files from a Canadian family medicine residency program. Residents who commenced an urban family medicine residency program between the years of 2006 and 2014 were included in the study.
Results: Five hundred nine family medicine residents were included in data analysis. Residents older than 30 years were 2.33 times (95% CI: 1.27-4.26) more likely to encounter difficulty than residents aged 30 years or younger. Nontransfer residents were 8.85 times (95% CI: 1.17-66.67) more likely to encounter difficulty than transfer residents. The effects of sex, training site, international medical graduate status, and rotation order on the likelihood of encountering difficulty were nonsignificant.
Conclusions: Older and nontransfer residents may be facing unique circumstances and may benefit from additional support from the program.

Tujuan dari penelitian ini adalah menentukan faktor-faktor penyebab bahaya longsor di Kecamatan Kulawi melalui AHP dan memetakan lokasi yang berpotensi bahaya longsor berdasarkan analisis spasial. Pada penelitian ini digunakan 5 data faktor penyebab longsor yaitu data kemiringan lereng, curah hujan, jenis tanah, penggunaan lahan, dan kondisi geologi. Kemudian dilakukan  perhitungan bobot setiap parameter penyebab longsor menggunakan Metode AHP dan besar pengaruh dari setiap parameter terhadap kejadian longsor. Hasil perhitungan diperoleh bobot dari setiap parameter penyebab bencana longsor yaitu bobot kemiringan lereng 52%, bobot curah hujan 25%, bobot kondisi geologi (batuan) 12%, bobot jenis tanah 6% dan bobot penggunaan lahan 5%. Data-data penyebab longsor tersebut kemudian ditumpang susun (overlay) dengan peta yang ada dan menghitung nilai hazard (bahaya longsor). Berdasarkan hasil analisis spasial diperoleh, lokasi yang berpotensi longsor di Kecamatan Kulawi diklasifikasikan menjadi tidak bahaya, kurang bahaya, sedang, bahaya, dan sangat bahaya dengan luas daerah berturut-turut  25,13  (2,23%), 418,71  (37.17%), 560,78  (49,8 %), 103,78  (9,2%), dan 17,93  (1,96%). Kejadian longsor di Kecamatan Kulawi dipengaruhi oleh keadaan lahan yang dibuka masyarakat untuk areal perkebunan dan ladang pada kawasan yang derajat kemiringannya cukup tinggi.

Gamerek az iskolában
Authors: Szabó József
Published: April 2018

Az elektronikus játékok terjedése többek között a pszichológusok figyelmét is felkeltette, akik a játékfüggőség veszélyeire figyelmeztettek. A felállított hipotézis szerint a játékhasználatnak igen komoly haszna is lehet, segíti az együttműködést, a kommunikációt, új ismereteket is nyújt, de a csapatjátékon keresztül a stratégiai gondolkodást is támogatja. A kutatás arra kereste a választ, hogy a fiatalok milyennek látják a gamerek világát, hogyan ítélik meg a játékok hasznosságát, hogyan viszonyulnak a sporthoz, és mennyiben befolyásolja a játék a tanulmányi eredményeiket. A vizsgálat azt mutatja, hogy a fiúk és a lányok játékhasználata nem tér el jelentősen, a tanulmányi eredmények az intenzív játékhasználat mellett sem romlanak. Ugyanakkor a szabadidő kitöltésében az aktív sportolás is megjelenik, elsősorban a csapatjátékok. A gamerek világa más, mint a mai felnőtteké, és rendkívül sok pozitív, a mindennapi életben hasznosítható részt tartalmaz.

Computer gamers in school

The proliferation of computer games has primarily drawn the attention of psychologists, who warn of the dangers of game addiction. According to our hypothesis computer games might have several advantages; help and cooperation, communication, provide new information, even support the strategic way of thinking through team games. At the focus of this research is how young people see computer games, what advantages they find in them, how computer games help their approach to sports and how playing these games influences their school results. The research shows that there is no significant gender difference in their use of games, and young people’s school results are not affected even if they play games intensively. Moreover, their free time activities involve regular sports, mostly team sports. These young people see the world in a different way and computer games themselves enrich their everyday lives.

Okul
iklimi okullarda eğitim-öğretimin kalitesini belirleyen en önemli unsurdur.
Gürültü okul iklimini bozarak eğitim-öğretim faaliyetlerinin verimini düşürmektedir.
Bu araştırmanın amacı sınıf öğretmenlerin okullardaki gürültü kirliliğinin
düzeyi, nedenleri, etkileri ve kontrol edilmesi konusunda görüşlerini
değerlendirmektir. Çalışma nitel bir araştırma olup, olgu bilim deseninde
tasarlanmıştır. Bu çerçevede öğretmenlerin okulda gürültü ile ilgili sahip
oldukları bilgi, deneyim ve görüşlerin ortaya çıkarılmaya çalışılmıştır.
Araştırmanın sonucunda okuldaki gürültü kirliliğine ilişkin öğretmen görüşleri
yedi tema altında toplanmıştır. Bu temalar; “okulda gürültü düzeyi”, “gürültü
kirliliği kavramının anlamı”, “okuldaki gürültünün sebepleri”, “okuldaki
gürültünün yoğunlaştığı yerler ve zamanlar”, “öğretmenlerin gürültüye karşı
verdikleri tepkiler”, “gürültünün eğitsel, fizyolojik ve psikolojik etkileri” ve “öğretmenlerin
gürültünün azaltılması veya engellenmesine dair görüşleri” şeklindedir.
Öğretmenlerin en çok dile getirdiği söylemler “okuldaki gürültünün sebepleri”
ve “gürültünün eğitsel, fizyolojik ve psikolojik etkileri” temaları altında
olduğu dikkat çekmektedir.
