Se realizÃ³ una investigaciÃ³n descriptiva para determinar la percepciÃ³n sobre la formaciÃ³n en medicina familiar en 12 universidades del PerÃº. La muestra estuvo conformada por 48 mÃ©dicos residentes de ambos sexos, con edades entre 26 y 45 aÃ±os, usando una encuesta estructurada. Resultados: 61.7% de la poblaciÃ³n estudiada fue de sexo femenino, 69.6% entre 26 y 35 aÃ±os, 60.9% cursaba el tercer aÃ±o, 51.1% estudiaban en universidades nacionales; el 31.9% seleccionÃ³ la universidad por su prestigio, y la modalidad de ingreso fue en 57.4% en primera opciÃ³n. Respecto al campo clÃ­nico, 61.7% lo calificÃ³ como regular para la formaciÃ³n acadÃ©mica y 36.2% considerÃ³ que no contaba con servicios adecuados en cuanto a alimentaciÃ³n, estar de reposo, servicios higiÃ©nicos. En relaciÃ³n a la estructura acadÃ©mica, el 85.1% contÃ³ con currÃ­culo, el 66% con sÃ­labo en forma oportuna y el 51.1% refiriÃ³ tener a disposiciÃ³n el servicio universitario de biblioteca virtual.

Influence of Process Methods on the Hepatoprotective Effect of Curcumin Analogs Synthesized from Culilawan Oil in Mice (Mus musculus L.) with CCl₄ Induced Liver Damage
Authors: Kapelle Imanuel B. D. , Manalu Wasmen , Mainassy Meillisa C.
Published: September 2019

One of the downstream products which can be synthesized from culilawan oil is an analog curcumin compound (AKS) with a dioxolane ring. AKS products can be synthesized using conventional and microwave methods. The method of synthesis can influence physical properties, compound geometry, and pharmacological effects. The purpose of this study was to determine the effect of the processing method on the hepatoprotective ability of AKS, and to determine a protective dose. AKS was synthesized using insulated safrole compounds from Lawang oil and involved isomerization, oxidation, and aldol condensation of curcumin analogues. At the final stage of the analog curcumin synthesis process, 2 different methods were employed: the conventional method heated the chemical in a water bath at 30 °C for 3 hours, the microwave method heated the chemical using 140 watts of power for 2 minutes. Analogs were tested in vivo in mice (Mus musculus L.) with CCl₄ induced liver damage. Hepatoprotective efficacy of AKS products processed by the conventional method and the microwave method were compared using histology and liver enzyme (AST and ALT) assessment. Animals treated with conventionally produced AKS products had lower AST and lower ALT levels—and fewer histological signs of liver damage at a lower dose of AKS—than seen in either untreated animals or those treated with microwave produced AKS. Thus, products that are processed by conventional methods are more hepatoprotective.
Sanctus: An Architecture for Trusted Products
Authors: Shore Malcolm , Clark Andy , Zeadally Sherali
Published: September 2019

The last two decades have seen a fundamental shift in the manufacturing, sourcing and operation of technology, which has raised concerns in state security agencies about the cybersecurity risk to government and critical infrastructure. Sophisticated cyber attacks continue to be launched by state actors worldwide, while the engineering practices in common use have failed to deliver a commensurate improvement in technology cyber security. Cyber attacks continue to be successful against commercial networks, leading the US Government to encourage government agencies to look towards models such as zero-trust networking and tailored trustworthy spaces. There has been progress in product engineering, with formal methodologies such as Correctness by Construction (CbyC) successfully producing commercial products with increased trustworthiness. However, the adoption of these techniques has been limited, and governments are now increasingly resorting to an approach of technology Balkanization, where import and use of products and components may be restricted based on their country of origin. Even in the early stages of this strategy, the effect upon the economy is significantly adverse. We propose an alternative to technology Balkanization by combining trustworthy engineering approaches with the use of a national security component we call a sanctum which together can deliver sovereign trust.

Authors: R. Jegan Murugan , V. Manivannan
Published: September 2019

Background: To assess the etiology, clinical profile, complications, outcome and prognosis of children admitted in the paediatric ICU with thrombocytopeniaMethods: This study was done on children admitted to the paediatric ICU of Tirunelveli Medical College Hospital during the period from December 2011 to April 2012. 112 consecutive  patients aged  2 months to 12 years with platelet counts less than 1 lakh were studied.Results: One in 6.25 children admitted in the paediatric ICU developed thrombocytopenia(15.95%incidence).The commonest age group of presentation of is 6-10 years(47.3%).Infants(45.5%) died more. Dengue(58.8%) was the commonest etiology, followed by enteric fever(11.6%), acute lymphoblastic leukemia (all 4.5%), septicemia(4.5%), plasmodium vivax malaria (2.7%). Leading cause of mortality is dengue shock syndrome(DSS  44.4%). The most common presenting symptom among the study group is fever(95.5%). Abdominal distension and pedal edema were significantly associated with low platelet counts, bleeding manifestations, increased transfusion needs and a  poor outcome. The presence of Altered sensorium, tachycardia, tachypnea, shock, seizures at presentation were all associated with significant bleeding and high mortality. Gastrointestinal bleed(41.07%) was the commonest bleeding manifestation. There was no significant correlation between the exact platelet counts and the bleeding. Children with counts less than 10,000  had a poor outcome.(57.1% mortality). Gall bladder wall edema and pleural effusion in Ultrasound correlate significantly with bleeding.Conclusions:  Thrombocytopenia is common in sick children in  paediatric ICU and has a definite bearing on prognosis. Infants have poor prognosis and need intensive monitoring. Mortality predictors, if present, need aggressive management. There is no role for prophylactic transfusions, as platelet counts do not correlate with bleeding.

Staircase-Like Crack Progression Due to Hydrogen Embrittlement of Cold-Worked Steel Strand
Authors: Fernandez Joseph Rogelio
Published: September 2019

Stressed carbon steel strand in an ungrouted duct susceptibility to pitting corrosion is low due to surface corrosion, but susceptibility of steel strand to Hydrogen Embrittlement (HE) can increase under those conditions.

 

The HE will facilitate crack growth within the strand. Various crack propagation mechanisms, such as longitudinal splitting and shear-cracking, have been shown as possible strand failure mechanisms by themselves in strand, but this may not be true in stressed strand in piles that has been embrittled by Hydrogen and without pre-cracking (Cracks initiating from stress concentrations naturally rather than with notching). Concentration measurements were performed to determine the level of Hydrogen involved in the embrittlement.

 

Results indicate that the fracture mechanism differs from shear cracking or longitudinal splitting alone as previously shown, but is a multi-step process of crack propagation starting perpendicular to stress, followed by variations of inter-lamellae longitudinal splitting at brittle region of lamellae and shear cracking at breaks in the lamellae. This process results in the crack following a “staircase” progression, and finally leading to ductile overload once cross-section has been significantly reduced. This fracture mechanism was also shown to be valid whether the strand was stressed by bending or mult-axially by stressing through a duct.

Причины, сдерживающие освоение маломасштабных непромышленных золотоносных россыпей
Authors: Глотов Валерий Васильевич
Published: September 2019

Рассмотрено современное состояние незаконной добычи золота из маломасштабных непромышленных золотоносных россыпей, а также причины, препятствующие разрешению этой важной народно-хозяйственной проблемы. Россия имеет богатый исторический опыт добычи золота силами частных лиц, что, несомненно, отражалось на пополнении золотого запаса страны, способствовало повышению занятости населения, обеспечивало вполне приемлемый жизненный уровень. Современные условия таковы, что запрет на вольноприносительство приводит к хищению золота, казна при этом не имеет дохода, а правоохранители имеют большие проблемы. Решить проблему возможно путем изменения действующих законов, применения нетрадиционных способов разработки маломасштабных непромышленных золотоносных россыпей. Это позволит создать новые хорошо оплачиваемые рабочие места, получить заметные социально-экономические выгоды, а добытое золото поступит в государственную казну, а не в криминальные структуры.

The high and increasing rate of uncertainty in the world’s Foreign Exchange Market (FEM) is one that poses a great concern to the market players, traders and policy makers. There is need to come up with reliable and sophisticated models foreign exchange rate and its determinants in order to predict their future values hence reduce the risks. This paper makes use of the Autoregressive Integrated Moving Average (ARIMA) model to forecast the foreign exchange rate of Turkey and inflation a major determinant of foreign exchange rate. This paper provides that ARIMA(3,1,3) is the best ARIMA model for forecasting foreign exchange rate of Turkey and that ARIMA(1,1,4) is the best ARIMA model for forecasting Turkey’s inflation (CPI). The paper also postulates that ceteris Paribas the foreign exchange rate of the lira against the dollar will be stable in the short run future. However, with the passage of time the suggested model of forecasting foreign exchange rate and inflation of Turkey should always be updated with current data. ACF, PACF, AIC and BIC together with forecasting performance measures like MAE, MAPE, Bias proportion, RMSE and Theil U statistics are very useful in the process of best model selection.

How dividend policy shakes the price of share of an enterprise` is one of the most significant research issues in the ground of modern investment and finance. This study examines the influence of dividend announcement on the price of the mutual fund those are registered in Dhaka Stock Exchange (DSE). The empirical part of this study uses “event study methodology” to know whether dividend announcement delivers any price sensitive information which creates a movement of the price of mutual funds. Although much studies are made on the topics of dividend policy, it is vague that whether dividend policy effects the stock price. The researcher who supports dividend irrelevance theory, argues that firm’s value should depend on earning power of the company, not on in which way the total earnings are divided into dividend and retained earnings and at what amount dividend are given to the shareholder of the company. This research surveys price of mutual funds those are registered in Dhaka Stock Exchange (DSE) surrounding 44 days of the dividend announcement date. In this study, we examine 13 samples & used event study technique that shows dividend announcement doesn’t convey any price sensitive information immediately after announcement of dividend but price of the mutual fund goes to change dramatically before 7 days of record date which proves that announcement of dividend affects the price of mutual fund registered in Dhaka Stock Exchange (DSE). Finally, T-test also postulates that price of stock responses to dividend announcement is not statistically significant immediately from dividend announcement date to 7 days after the announcement date. However, an opposite result, the T test identifies that price of stock responses to the announcement of dividend is statistically significant from the 7 days before record date to record date.

Banks are more likely to fail from operational risk than from credit risk, and internal control at banks create operational risk losses. The objective of this study is to investigate internal control risk assessment and operational risk of quoted banks in Nigeria. 16 selected quoted banks in the Nigerian stock exchange from 2013-2017 were studied based on the 2012 banking reform on corporate governance by the then CBN governor Sanusi Lamido Sanusi’s “Project Alpha Initiative” (PAI). Data were collected from banks published annual reports, CBN statistical bulletin, NDIC report, CBN fact book, company website and banks’ Pillar III disclosure report for the relevant years sampled for analysis. The analysis carried out included pooled OLS regression, fixed and random effect and Hausman tests to determine the most suitable model for result interpretation. This was conducted with the aid of E-View 7 software. The findings shows that internal control risk assessment (ET and PQ) has positive significant effect on Operational risk (OPR). It was recommended that banks should ensure that internal control unit personnel are qualified and adequately trained to carry out banking activities as this will go a long way in reducing the risks from operations.
Approaches to Thoracic and Lumbar Spine: Our 10 Years Review
Authors: Datta Parthasarahi
Published: September 2019

Background: Lesions of the Thoracic and lumbar spine (TL) are numerous. These lesions affect one or more columns (anterior, middle and posterior) of the spine and compress the spinal cords either from anterior and posterior, giving rise to the features of radiculo-myelopathy. These lesions can be approached either from the anterior or posterior aspect of the spine. We present our last 10 years experience regarding the comparison between two approaches. Methods: Retrospective analysis of records of all patients with thoracic and lumbar lesion treated in our hospital between January 2005 and June 2014 was performed. Over the last 10 years, we came across 186 patients of thoracic and lumbar lesion lesion who were operated either by anterior or posterior approach and were the focus of this study. Follow up ranged from 6 months to 7 years. Results: All the patients presented with neurological deficits. They were evaluated with investigation protocol of our hospital. Anterior approach was done in 38 cases (n = 38) and posterior approach was done in 148 cases (n = 148). We compared between the two groups in terms of perioperative complications, recovery, persisting symptoms and mortality. Conclusion: Complete recovery is better in the posterior approach (74.3%) v/s 52.6%) and morality is more in the anterior approach (7.9% v/s 1.3%).

This study was conducted to evaluate the reproductive performance of females of Oreochromis niloticus originating from a strain of distant origin and extensively exploited in fish farming (Nyakabera strain) and a local strain recently removed from the natural environment (Lac Kivu strain). The experiment was carried out in triplicate with fry of 4.9 to 6.3 g placed in earthen ponds for a period of 6 months, at the Nyakabera fish station in South Kivu, Democratic Republic of Congo. The comparison of the two strains focused on the size of the first sexual maturity, gonado-somatic ratio, fecundity, egg diameter and condition factor. The results showed that under similar managed rearing conditions, the Nyakabera strain reaches sexual maturity earlier and is characterized by a higher gonado-somatic ratio and higher relative fertility, but a worse condition compared to the Lac Kivu strain. These differences, which indicate a better reproductive success of the Nyakabera strain, are related to the origin and the history of domestication, which are just as different from these two strains.

This study was conducted to find out head teachers' perception of the implementation of the capitation grant scheme in Sunyani West East District of the Brong Ahafo Region. The study specifically focused on explaining how head teachers conceptualised the concept of capitation grant scheme, the implementation process, and the challenges associated with the implementation of the scheme. A descriptive research design was adopted for the study, and a questionnaire and an interview guide were designed and administered to a sample of 40 head teachers from the district in the Region. The analysis of data revealed that 70.0% of thehead teachers had an in-depth understanding of the source of capitation grant as being from the Government. The study, among others, found that the main challenges confronting the smooth implementations of the scheme were delay in the release of funds and inadequate funds. It is recommended that Government should release adequate amount of the grant in good time (thus, before the beginning of each quarter) so that school heads will avoid pre-financing of school activities. Also, the Ghana Education Service should continue to train head teachers in financial management and administration for prudent use of funds.
Musculoskeletal Disorders of the Cervical Spine Following Neck Dissections Due to Malignancies of the Head And Neck
Authors: Mihaylova Zornitsa
Published: September 2019

Neck dissections are surgical interventions aiming the removal of lymph nodes from specific areas of the neck, together with non-lymphatic structures falling within the scope of the operation – m. sternocleidomasstoideus (MSCM), v. jugularis interna (VJI), n. accessorius (N.XI). Due to the involvement of important anatomical structures in the neck dissections, postoperative outcoomes and complications associated with impaired function of the musculoskeletal system of the neck arise.

The purpose of the present study is to determine the degree of cervical spine movements depending on the volume of surgical neck dissection.

            Methods. The goniometry method was used to evaluate the motor function of the operated patients. The results obtained were analyzed via SPSS Vers23.0.

Results. A statistically significant difference was observed postoperatively at the 3rd month in all directions of movement studied in the three groups of operative interventions (neck dissections): flexion – F(2,65)=643.566, p<0.001; extension – F(2,65)=445.045, p<0.001; lateral flexion – F(2,65)=314.077, p<0.001; rotation – F(2,65)=121.980, p<0.001.

            Conclusion. Assessment of the cervical spine shows that all directions of movement are affected, most significantly affecting lateral flexion in all groups of operated patients with neck dissection.

Przełomem w rozpętaniu masowego terroru w ZSRR stało się lutowo-marcowe plenum KC WKP(b) (1937), które zainicjowało działania NKWD na rzecz likwidacji „kontrrewolucyjnych elementów”. Równolegle do tych działań prowadzone były od lipca 1937 r. do listopada 1938 r. operacje przeciwko „wrogim narodowościom” – potencjalną „piątą kolumną”, „bazą powstańczą” na wypadek wojny. Obejmowały one wszystkie warstwy ludności. Skazano wtedy ponad 335 tys. osób, spośród których rozstrzelano prawie 74%. Głównym celem było zniszczenie resztek „nacjonalistycznych elementów” – bazy dla zagranicznych wywiadów. Na przykładzie tej operacji w Kirgizji zostały przedstawione jej etapy (przygotowania, aresztowanie, śledztwo, wyrok) oraz „technologia” represji. Nawiązując do „operacji polskiej” NKWD, przytoczono bliższe informacje archiwalne o sprawie Ludwika Krynickiego. Dokonano analizy pochodzenia narodowościowego 137 ofiar, których szczątki wydobyto w Czon-Tasz, a także składu narodowego prawie 21 tys. represjonowanych w Kirgizji w latach 1918–1953 (m.in. 180 Polaków).

Published: September 2019

A dinâmica molecular de Car-Parrinello é uma ferramenta que vem sendo aplicada com grande frequência, uma vez que ela realiza simulações de sistemas moleculares dinâmicos em nível Ab initio. Neste trabalho, foi realizado um estudo da estrutura da molécula do dimetilcarbonato para a verificação do controle da adiabaticidade do sistema resultante da simulação através da dinâmica molecular de Car-Parrinello. Inicialmente, as propriedades estruturais da molécula do DMC foram verificadas através de cálculos Ab initio, pelo pacote de programas Gaussian 2003, em que foram utilizados o conjunto de base 6-31G* e o funcional de correlação e troca B3LYP. As simulações foram realizadas pelo pacote de programas QuantumEXEPRESSO, em que variou-se a massa fictícia, mantendo-se o tamanho do passo fixo e, em seguida, mantendo-se a massa fictícia fixa e variando o tamanho do passo de tempo.
