Evaluación de la Calidad Técnica Científico en el Servicio de Emergencia del Hospital Abel Gilbert Pontón Año 2018 – 2019
Authors: Guerrero Lambida Rosa Angélica
Published: April 2019

La mejora continua de la calidad asistencial dentro de los sistemas nacionales de salud es uno de los objetivos principales para el MSP e instituciones privadas. Uno de los componentes a evaluar es la calidad técnico científica para lograr la eficiencia, eficacia y efectividad del servicio evaluado para lo cual se han elaborado varias herramientas de identificación y evaluación de problemas, siendo uno de ellos los indicadores de salud. 

Este estudio fue de tipo transversal retrospectivo de carácter analítico, en el que se evalúa la calidad técnico científico del área de emergencia de una forma objetiva por medio de indicadores

El universo de 1550 pacientes atendidos en 6 meses, se tomó una muestra probabilística de 300 casos clínicos tomados al azar, de las 10 patologías más frecuentemente atendidos en el área de emergencia del hospital de especialidades Abel Gilbert Pontón con su respectivo protocolo; se consideró la información obtenido en los formatos digitálicos 008 y 005 durante el periodo de julio del 2018 hasta enero del 2019.

La muestra fue compuesta por 300 historias clínicas, los valores obtenidos serán los numeradores y los denominadores de los indicadores elaborados para la evaluación técnica científica del área de emergencia con un valor estándar inicial mayor del 70% como óptimo según las guías españolas de Andalucía y OMS que se tomaron como referencia sobre calidad asistencial.

Como resultado se obtuvo que la evaluación realizada de la calidad técnico científico del servicio de emergencia identificó como principal problema la demora en la toma de decisiones en relación a la conducta definitiva con los pacientes, conduciendo a una estancia mayor a las 6 horas, valor que no está en relación a una calidad asistencial optima y que se relacionaría con la falta de socialización de los protocolos del servicio y actualización de los mismos que fueron otros de los problemas identificados, el siguiente paso es la elaboración de planes de acción como parte del ciclo de mejora continua en la calidad asistencial.

Este proyecto se encaminó al estudio, diseño y construcción de un sistema de control electrónico para medir el desgaste en los forros de las pastillas de frenos en un automóvil de competición. Se realizó un análisis sobre el problema que se origina en los discos de freno al sufrir daños prematuros e irreparables debido a los sistemas de alerta que traen incorporados, siendo los causantes del problema. Se realizó la selección e implementación de componentes electrónicos para solucionar el problema con los discos de frenos, garantizando su desempeño, su cuidado respectivo, el incremento de la vida útil tanto del disco como del forro de las pastillas de freno y sobre todo velar por la integridad del piloto del vehículo. Los resultados obtenidos en las pruebas fueron excelentes, se logró consumir 15 % más cantidad de forros de lo que normalmente se logra con la lámina de acero y evitar daños en la superficie de los discos. Mediante los cálculos de desgaste se determina que los forros no afectan al sistema incorporado ya que de igual manera mide el desgaste que sufren los mismos, garantizando su normal funcionamiento y la certeza de poder utilizar cualquier tipo de forros de frenos.
Chapter 2a: Virology

Published: April 2019

• TBEV is the most medically important member of the tick-borne serocomplex group within the genus Flavivirus, family Flaviviridae. • Three antigenic subtypes of TBEV correspond to the 3 recognized genotypes: European (TBEV-EU), also known as Western, Far Eastern (TBEV-FE), and Siberian (TBEV-SIB). Additional 2 genotypes have been identified in the Irkutsk region of Russia, currently named TBE virus Baikalian subtype (TBEV-BKL) and TBE virus Himalaya subtype (Himalayan and “178-79” group; TBEV-HIM). • TBEV virions are small enveloped spherical particles about 50 nm in diameter. • The TBEV genome consists of a single-stranded positive sense RNA molecule. • The genome encodes one open reading frame (ORF), which is flanked by untranslated (non-coding) regions (UTRs). • The 5′-UTR end has a methylated nucleotide cap for canonical cellular translation. The 3′-UTR is not polyadenylated and is characterized by extensive length and sequence heterogeneity. • The ORF encodes one large polyprotein, which is co- and post-translationally cleaved into 3 structural proteins (C, prM, and E) and 7 non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). • TBEV replicates in the cytoplasm of the host cell in close association with virus-induced intracellular membrane structures. Virus assembly occurs in the endoplasmic reticulum. The immature virions are transported to the Golgi complex, and mature virions pass through the host secretory pathway and are finally released from the host cell by fusion of the transport vesicle membrane with the plasma membrane.
Chapter 5: TBE in adults

Published: April 2019

• TBE is the most important tick-borne arbovirus disease of humans. Epidemiological data indicate a trend towards an increasing severity with higher age.
• A number of possible genetic and non-genetic risk factors have been identified, which might have an impact on the manifestation and severity of human disease.
• Different TBEV strains seem to cause differing clinical courses of disease. While the TBE-Eu mainly causes a biphasic course, the clinical course of TBEV-FE and TBEV-Sib are mainly monophasic.
• The diagnosis of TBE is based on serological tests.
• So far there is no effective treatment of TBEV infections.

Protease-activated receptor-2 regulates glial scar formation via JNK signaling
Authors: Li Tian-Zun , Deng Hui , Liu Qiang , Xia Yong-Zhi , Darwazeh Rami , Yan Yi
Published: April 2019

The study aimed to determine the effects of protease-activated receptor-2 (PAR-2) on glial scar formation after spinal cord injury (SCI) in Sprague–Dawley (SD) rats and the underlying mechanisms. Rivlin and Tator’s acute extradural clip compression injury (CCI) model of severe SCI was established in this study. Animals were divided into four groups: 1) sham group (laminectomy only); 2) model group, treated with normal saline; 3) PAR-2 inhibitor group; 4) PAR-2 activator group. Enhanced GFAP and vimentin expression were the markers of glial scar formation. To determine whether JNK was involved in the effects of PAR-2 on GFAP and vimentin expression, we administered anisomycin (a JNK activator) in the presence of PAR-2 inhibitor and SP600125 (a JNK inhibitor) in the presence of PAR-2 activator. At 1, 7, 14 and 28 day after SCI, Basso, Beattie, and Bresnahan (BBB) locomotor score test was used to assess the locomotor functional recovery; immunofluorescence and western blot analysis were used to assess the expression level of GFAP, vimentin and p-JNK. Double immunofluorescence staining with GFAP and tubulin beta was used to assess the glial scar formation and the remaining neurons. Results suggested that PAR-2 is involved in glial scar formation and reduces neurons residues which can cause a further worsening in the functional outcomes after SCI via JNK signaling. Therefore, it may be effective to target PAR-2 in the treatment of SCI.

Although the fluid therapy plays a fundamental role in the management of polytrauma patients (PP), a tool which could determine it appropriately is still lacking. The aim of this study was to evaluate the application of a bioimpedance spectroscopy (BIS) for body fluids volume and distribution monitoring in these patients. This prospective, observational study was performed on 25 severe PP and 25 healthy subjects. The body fluids composition was repeatedly assessed using BIS between days 3 to 11 of intensive care unit stay while the impact of fluid intake and balance was evaluated. Fluid intake correlated significantly with fluid excess (FE) in edemas, and their values were significantly higher in comparison with the control group. FE was strongly associated with cumulative fluid balance (p<0.0001; r=0.719). Furthermore, this parameter was associated with the entire duration of mechanical ventilation (p=0.001, r=0.791) independently of injury severity score. In conclusion, BIS measured FE could be useful in PP who already achieved negative fluid balance in prevention the risk of repeated hypovolemia through inappropriate fluid restriction. What is more, measured FE has a certain prognostic value. Further studies are required to confirm BIS as a potential instrument for the improvement of PP outcome.

Borderline Personality Disorder and Religiosity: Exploring the Relationship
Authors: Hosack Lisa
Published: April 2019

The negative effects of borderline personality disorder (BPD) are widely documented. And while religiosity has been found to be generally beneficial for individuals with clinical disorders, little is known about the relationship of religiosity and personality disorders, including BPD.  The purpose of this quantitative, cross-sectional study was to examine the relationship between BPD and two important components of religiosity. The first was termed religious quest and was defined in the study as the level of one’s internal openness to faith and spirituality. The other was defined as religious engagement and was defined in the study as the external, behavioral marks of religious faith such as prayer and attendance at religious events. A survey comprised of several validated measures was administered to undergraduate students within a large public university in the Midwest (N = 466).

Fursatnâme adlı eseri üzerinde durulacaktır. Gelibolulu Âlî, eserini 1580 (980)
yılında sadrazam Sinan Paşa’nın isteğiyle yazmaya başlamıştır. Eser, Gelibolulu
Âlî’nin, Lala Mustafa Paşa’nın 1578-80 yıllarında düzenlediği Azerbaycan ve Şirvan
seferlerini anlattığı Nusretnâme adlı eserinin devamıdır ve Sinan Paşa’nın Gürcistan
seferini konu edinmektedir. Ancak Sinan Paşa’nın tasarladığı fetihleri yapmadan
Temmuz 1581’de aniden İstanbul’a dönmesi üzerine Gelibolulu Âlî, eser üzerinde çalışmayı
bırakmış ve eser yarım kalmıştır. Eser hacim olarak küçük olmakla birlikte,
gerek içeriği gerekse Gelibolulu Âli’nin hayatındaki etkisi açısından büyük öneme
sahiptir.

Faut-il brûler les ponts ? La poétique mode d’emploi
Authors: Meshkinfam Gabriel
Published: April 2019

La poétique est un faire, un geste, une manœuvre que le XXe siècle n’a cessé d’interroger selon une triple dimension : sa spatialité, son articulation avec la pensée et sa mise en scène du concept de différence. Pour rendre compte de ce mouvement si contemporain cet article entend proposer une traversée générale de ces considérations sur la poétique selon un schéma simple : la construction d’un pont. D’abord, sa conception, c’est-à-dire la compréhension de son essence ambivalente, oscillant toujours entre le lien et la disjonction. Puis, l’établissement de ses fondations autour du concept genettien de spatialité linguistique. Viennent ensuite les différentes considérations techniques et pragmatiques où la poésie jouera le rôle de maquette. Et parmi ces considérations, la question fondamentale : est-il nécessaire de détruire (ou déconstruire) le pont ?

Published: April 2019

Maisto produktai gali sukelti įvairių nepageidaujamų reakcijų, kurios vadinamos padidėjusiu jautrumu maisto produktams. Tyrimo tikslas buvo įvertinti Kauno mieste ikimokyklines įstaigas lankančių vaikų jautrumo maistui dažnį bei tėvų (globėjų) nuomonę ir žinias apie vaikų jautrumą maistui. Anketinėje apklausoje dalyvavo 1143 vaikų tėvai. Nustatyta, kad jautrumo maistui dažnis ikimokyklinėse įstaigose siekė 15,2 proc., (n=174), iš jų 98 (17,5 proc.) berniukai ir 76 (13,0 proc.) mergaitės. Mergaitės dažniau buvo jautrios šokoladui (61,8 proc.), citrusiniams vaisiams (50,0 proc.) ir pienui (43,4 proc.); tuo tarpu berniukai buvo labiau jautrūs pienui (54,1 proc.), šokoladui (45,9 proc.), kiaušiniams (39,8 proc.). Dažniausiai vaikams pasireiškė alerginės odos reakcijos (80,6 proc. berniukų ir 77,7 proc. mergaičių), rečiau – sloga, čiaudulys (41,8 proc. berniukų ir 31,6 proc. mergaičių). Tėvų nuomone, maisto alergijas lemia genetiniai veiksniai, mityba bei aplinkos tarša. Statistiškai reikšmingai daugiau žinių apie alergiją maistui ir anafilaksinio šoko galimybę turėjo aukštąjį išsilavinimą įgiję respondentai (atitinkamai ŠS = 2,73 (95 proc. PI 1,25-6,31) ir ŠS=2,83 (95 proc. PI 1,98-4,95). Vaikų jautrumas maistui lėmė didžiosios dalies respondentų šeimų gyvenimo kokybę (82,2 proc.), siekiant užtikrinti tinkamą vaikų mitybą bei gydymą.

Published: April 2019

Vilniaus gimdymo namuose buvo atlikta retrospektyvioji 187 ligos istorijų analizė moterų, kurioms gimdymas buvo sužadintas prostaglandinais, skiriant misoprostolio tabletes į makštį arba po liežuviu. Tiriamosios suskirstytos į dvi grupes: moterys, kurioms buvo gimdymas sužadintas skiriant misoprostolio tabletes per makštį (67 moterys) bei moterys, kurioms sužadinimas buvo atliktas skiriant misoprostolio tabletes po liežuviu (120 moterų). Grupės buvo lygintos pagal mekonijaus buvimą vaisiaus vandenyse, gimdymo baigtis ir gimdymo užbaigimo būdo indikacijas. Rezultatai. Lyginant tiriamųjų grupes, moterų, kurioms misoprostolis buvo skirtas į makštį, vaisiaus vandenų su mekonijumi dažnis yra net 9,85 proc. didesnis, o cezario pjūvio operacijų skaičius 3,76 proc. mažesnis nei moterų, kurioms misoprostolis buvo skirtas po liežuviu. Tačiau šie skirtumai yra statistiškai nereikšmingi. Abiejose grupėse daugiausia moterų gimdė natūraliuoju būdu. Instrumentinių gimdymų užbaigimo kiekis bei indikacijos jam reikšmingai nesiskyrė tarp abiejų grupių. Lyginant cezario pjūvio operacijų dažnį tarp nesužadintų gimdymų bei sužadintų misoprostolio pagalba statistiškai reikšmingo skirtumo neaptikta.
ENDODONTIJOJE NAUDOJAMŲ DANTŲ ŠAKNIES KANALŲ MINKŠTŲJŲ UŽPILDŲ DAROMA ĮTAKA STIKLO PLUOŠTO KAIŠČIŲ RETENCINEI JĖGAI

Pagrindinis endodontinio gydymo tikslas yra užpildyti dantų šaknų kanalus trimatėje erdvėje, kad išvengtume kanalų reinfekcijos ir apsaugotume viršūninio apydančio audinius. Svarbu paminėti, kad ne tik kanalų apikalinės dalies, bet ir vainikinės dalies sandarumas yra svarbus endodontinio gydymo sėkmei. Šio darbo tikslas buvo įvertinti, susisteminti ir išanalizuoti mokslinėje literatūroje pateikiamus duomenis apie endodontijoje naudojamų DŠKMU įtaką SPK retencinėms savybėms. Šioje sisteminėje apžvalgoje išanalizuoti 6 pilno teksto straipsniai. Remiantis atrinktų straipsnių rezultatų duomenimis, galime teigti, kad epoksidinių dervų turintys DŠKMU pasižymi aukštesne retencine jėga nei kitų grupių DŠKMU. Pastebėta, kad aukštesnė retencinė jėga gaunama tada, kai SPK cementuojamas ne iš karto po endodontinio gydymo, o praėjus 7 – 15 dienų, arba 6 mėnesiams. Labiausiai retencinės jėgos praradimui turi įtakos DŠKMU pasirinkimas ir SPK cementavimo laikas, o ne cemento rūšis.

Intratekalinė chemoterapija – chemoterapijos vaistų suleidimas į stuburo smegenų kanalą, siekiant išgydyti onkologinę ligą arba išvengti jos recidyvo centrinėje nervų sistemoje. Dažniausiai šiam tikslui naudojami vaistai yra metotreksatas, citarabinas ir gliukokortikoidai. Jie gali būti naudojami atskirai arba kartu, t.y. taikoma triguba intratekalinė chemoterapija. Vaistai suleidžiami į subarachnoidinį tarpą atlikus juosmeninę punkciją. Po procedūros pacientą svarbu stebėti dėl nepageidaujamų chemoterapijos preparatų reiškinių (aseptinio meningito, cheminio arachnoidito, encefalopatijos, traukulių ir kt.) ir juosmeninės punkcijos komplikacijų (galvos ar nugaros skausmo, kraujavimo, infekcijos ir kt.).

Heterotopinis nėštumas yra būklė, kai tuo pačiu metu pasireiškia nėštumas gimdoje ir už gimdos ribų. Tai retas reiškinys, tačiau dėl taikomos pagalbinio apvaisinimo technologijos jo paplitimas padidėjo beveik 10 kartų. Heterotopinio nėštumo rizikos veiksniai: vyresnis nėščiosios amžius, rūkymas, dubens uždegiminė liga, kiaušidžių stimuliacija ar operacijos, intrauterinės spiralės naudojimas bei pagalbinis apvai-sinimas. Net 50 proc. moterų, kurioms diagnozuotas heterotopinis nėštumas, neturi rizikos veiksnių. Heterotopinio nėštumo diagnostiniai kriterijai yra ūminis pilvo skausmas, echoskopiniai duomenys (skystis Duglaso ertmėje), sumažėjęs hemoglobino kiekis. Konservatyvus gydymas kalio chlorido (KCl) ar hi-perosmosinio gliukozės tirpalo injekcija į heterotopinį gestacinį maišelį. Esant neveiksmingam konservatyviam gydymui arba esant ūmiai būklei taikoma skubi laparoskopija arba laparotomija, atliekant tubotomiją arba tubektomiją.

Tyrimo objektas. Riebios veido odos poveikis gyvenimo kokybei. Tyrimo tikslas. Išanalizuoti jaunų žmonių gyvenimo kokybę ir riebios veido odos sąsajas.

Tyrimo medžiaga ir metodai. Atliekant tyrimą taiky-tas originalus klausimynas, grįstas mokslo informacijos šaltiniais. Apklausti 396 18-35 metų amžiaus respondentai, iš kurių 128 turintys riebią veido odą. Duomenys analizuoti naudojant IMB SPSS Statistics (version 19) programinės įrangos duomenų paketą. Analizuotiems duomenims buvo naudojami: Šapiro Vilko (Shapiro-Wilk), Kolmogorovo-Smirnovo (Kolmagorov-Smirnov) ir Kruskalio Voliso (Kruskal-Wallis) neparametriniai kriterijai, duomenys buvo koduojami, skaičiuojami vidurkiai, standartiniai nuokrypiai, mediana, dažniai, procentai, statistinis reikšmingumas.

Tyrimo rezultatai. Atlikus tyrimą nustatyta, kad riebią veido odą turintys jauni žmonės patiria socialinę ir emocinę atskirtį. Jie labiau vengia bendrauti su kitais žmonėmis, vengia viešų susibūrimų, dėl savo odos yra linkę būti namuose, jaučia stresą ir kitus nemalonius jausmus. Analizuojant surinktus duomenis pagal amžiaus grupes nustatyta, kad 18-23 metų amžiaus respondentai labiau jaučia riebios veido odos įtaką socialinei bei emocinei būsenai.

Išvados. Atlikus tyrimą paaiškėjo, kad riebi veido oda sukelia psichologinį diskomfortą ir turi įtakos jaunų žmonių gyvenimo kokybei. Nustatyta, kad riebi veido oda blogina ją turinčių žmonių socialinę ir emocinę būseną.

Association of Organizational Attributes With Human Resource Disclosure: Evidence From Bangladeshi Banks
Authors: Ali Mohammad , Ahmed Tania
Published: April 2019

This paper aims to investigate the extent to which organizational attributes are associated with the human resource disclosure of banking organizations. Content analysis is used to collect the data from annual reports available on the bank’s website and unweighted disclosure index is employed to record the score of HR items. Descriptive statistics is used to analyse the extent of HR disclosure and multiple linear regression model is carried out to analyse the impact of the determinants including length of service, size of the bank, profitability, total number of employees and total number of pages on the explained variable. The study endorses that the highest reported item is the description of the staff whereas the least reported item is the performance of the employee. The result approves that only two attributes including the profitability of the banks and the total number of pages of the annual reports are significantly and positively associated with the level of human resource disclosure of banks. But the other attributes including length of service, size of the bank and total number of employees have no significant impact on HR disclosure.

Published: April 2019

The current study endeavors to explore the effects of oscillations in exchange rate on commodity trade flow between Pakistan and China, employing the data for the time period of 1982-2017. Applying ARDL Bound Testing approach, we find that 63% exporting and 55% importing industries of Pakistan demonstrate the co-integration. Further, employing ARDL technique, the current study deduces that 55% in the short run and 18% exporting industries in the long run respond to the volatility. In imports function, the volatility affects 56% industries in short as well as long run. Intriguingly, two exporting industries coded as 651 (57% share) & 652 (13% share) do not respond to the volatility. And, this is the unique aspect of our study.
Whole Blood mRNA Expression Pattern Differentiates AD Patients and Healthy Controls Through Bioinformatics Analysis
Authors: Zhu Mengjia , Wang Liqun
Published: April 2019

Background: Gene chip has a wide range of applications in screening disease markers.Methods: GSE63063 dataset including 238 healthy controls and 285 patients with Alzheimer’s disease (AD) was downloaded to investigate the whole blood mRNA expression pattern. Lumi and LIMMA packages of R software were used to screening differential-expressed genes (DEGs). We functionally annotate DEGs through DAVID database. Then STRING database and Cytoscape software were used to construct protein-protein interaction models for hub genes.Results: Our results indicated that 51 DEGs altered in AD patients compared with healthy controls. These DEGs was associated with transcription (BP), RNA binding (MF) and ribosome (CC) terms and the ribosome signaling pathway. In addition, Ribosomal protein S17 (RPS17) was identified as the top 1 in hub genes using maximal clique centrality. RPS17 mutations reduced erythrocyte production and impaired brain development. Finally, the expression levels of the three genes (NDUFA1, RPL36AL, and NDUFS5) showed a good predictive effect.Conclusion: In conclusion, we explored the expression of genes in the AD blood and NDUFA1 may be a potential biomarker for predicting AD.
Patient empowerment and involvement in telemedicine
Authors: Nielsen Marie Konge , Johannessen Helle
Published: April 2019

Objective: Telemedicine is a rapidly expanding area, and this article discusses the implications of patient empowerment and user involvement in relation to frail patients. Our aim is to critique the mechanical way telemedicine is being implemented in the health sector.Methods: We present the basic ideas of empowerment and user involvement behind telemedicine, exemplifying them with a case of user resistance to telemedicine. Four logics of empowerment are employed to identify the underlying rationale in specific cases of telemedicine. The case comes from a large evaluation of new welfare technology products. The data consist mainly of written documents and an interview.Results: Telemedicine is often considered a way to increase empowerment and user involvement in healthcare. The majority of the geriatric patients in the described case refused to engage in telemedicine, preferring instead to be hospitalized. The case appeared to be driven primarily by a professional logic of empowerment. User involvement and empowerment are discussed in terms of their demands and implication for users, such as 1) intrusion on the private sphere, i.e., the home and 2) the question of the responsibility for treatment and 3) the expectation, that the capabilities and resources of patients and relatives may increase.Conclusions: Although telemedicine is acknowledged as relevant, a mechanical approach too often hampers empowerment for the patient. Some patient groups may not feel safe using telemedicine, in which case user involvement and empowerment are not possible.

Published: April 2019

In this research, the main issue is to illustrate the huge differences between female and male characters’ choice of words and their linguistic and psychological effect of the novel’s A Passage to India by Forster (1924). The researchers have set some questions and attempted to answer them through using qualitative methods endorsed by Potter's (1999) and Lakoff's (1973). These qualitative methods are the ones which focus on vocabulary, word analysis, and word meaning. The main concern of these methods is to gather non-numerical data proofing our main idea even more by giving examples from the incidents in the novel. They also refer to the meanings, concepts, definitions, characteristics, metaphors, symbols, and description of things. The research comes out with some important findings. It is revealed that words alone do deliver the whole meaning. However, it is demonstrated that gender, body language, words of politeness, and punctuations that show the tone of voice do help words convey their effect more clearly. It is also found that females have strong tendency to use descriptive words to express their feelings. This makes females' language more pleasant than males'. It is further noticed that females use tag questions more commonly to seek approval. On the other hand, it is observed that males produce formal sentences to realize and ascertain dominance in their speech.
Figurative Language Comprehension in Schizophrenia and Its Neural Basis
Authors: Cheng Heben
Published: April 2019

Schizophrenia is a kind of serious mental disease, which may cause major impairment in patients’ social-cognitive ability. It has been found that pragmatic ability in schizophrenic patients is often impaired, especially for figurative language comprehension. Figurative language refers to irony, metaphor, idiom and the like. People with schizophrenia tend to interpret figurative language as its literal meaning, which is called schizophrenic concretism. By reviewing extant literature, we found that the literature concerning this topic mainly consists of two parts: behavioral studies and brain-imaging studies. The behavioral studies mainly explore how clinical factors and cognitive ability have an impact on figurative language comprehension. Brain-imaging studies mainly discuss hemisphere lateralization in schizophrenia and whether theory of mind network in schizophrenic patients is different from that of normal groups. We conclude that future research should further explore the relationship among figurative language comprehension, cognitive ability and clinical factors, and also reveal related neural mechanism.

Published: April 2019

The problem of economic empowerment of rural society is very complex because of various rural conditions with various limitations such as education level, skill, and lack of facilities and infrastructures among others are communication means which are expected to be able to bridge to interact in dealing with various problems in rural areas. The means of communication that can reach all the inferior rural areas is community radio. Radio as an information media has a strategic role in synergizing various resources and elements of both the government, private, community, college. Community radio can bring the distance between the various gaps that exist in rural communities. With the program of radio broadcast interactive dialogue will be an educational process to the community because there will be an exchange of ideas and education that can involve many parties and the community umm in solving various problems faced by the community; both in the strategic, tactical and technical levels that are mutually beneficial so that there will be mutualist symbiosis. Thus the sustainability of community economic empowerment activities will be more guaranteed sustainability.

Extracting super-resolution details directly from a diffraction-blurred image or part of its frequency spectrum
Authors: Sheffield Edward Y
Published: April 2019

It is usually believed that the low frequency part of a signal’s Fourier spectrum represents its profile, while the high frequency part represents its details. Conventional light microscopes filter out the high frequency parts of image signals, so that people cannot see the details of the samples (objects being imaged) in the blurred images. However, we find that in a certain “resolvable condition”, a signal’s low frequency and high frequency parts not only represent profile and details respectively. Actually, any one of them also contains the full information (including both profile and details) of the sample’s structure. Therefore, for samples with spatial frequency beyond diffraction-limit, even if the image’s high frequency part is filtered out by the microscope, it is still possible to extract the full information from the low frequency part. On the basis of the above findings, we propose the technique of Deconvolution Super-resolution (DeSu-re), including two methods. One method extracts the full information of the sample’s structure directly from the diffraction-blurred image, while the other extracts it directly from part of the observed image’s spectrum (e.g., low frequency part). Both theoretical analysis and simulation experiment support the above findings, and also verify the effectiveness of the proposed methods.
Aperture Antennas
Authors: Kozakoff Dennis J.
Published: November 2024

Aperture antennas include those having large planar areas such as parabolic reflectors. The classic technique used in the calculation of aperture antenna radiation patterns is applying the equivalence principle followed by physical optics approximations. The equivalence principle is based on replacing the physical antenna aperture with a virtual antenna aperture consisting of an ensemble of Huygens sources, each of which is a source of spherical wavelets. The total pattern is taken as a construction of these Huygens secondary waves. It can be further shown that a simple Fourier transform relation exists between the amplitude distribution of these sources and the radiation pattern in angle space. For many aperture antenna problems, the distribution can be assumed from theoretical considerations or determined empirically from near‐field probes of the aperture fields. But there are many other antennas such as horn antennas, where a virtual aperture can also be constructed in front of the physical aperture in order to model and analyze the antenna. Thus, an aperture antenna has more to do with the method used to model the antenna than its actual form.

For most aperture antenna problems, these classical techniques are adequate and give reasonably accurate results. However, more modern analysis techniques such as the method of moments (MoM), the finite‐element method (FEM), and the finite‐difference time‐domain (FDTD) method are also discussed. These methods are more robust and accurate, but the complexity and large amount of computer resources required must be traded off with the accuracy desired. Generally, they are infeasible for high‐gain antennas.
Dielectric Loaded Antennas
Authors: Shafai L.
Published: November 2024

Dielectric media affect the wave propagation by their reflective index. Their use in antennas can provide a number of diverse benefits. In applications such as high‐gain antennas, they influence the phase of the propagating waves, and thus influence the direction and gain of the transmitted waves. Lens antennas are typical examples that can be used alone, or in conjunction with other antennas, such as horn and microstrip antennas, to enhance their gain. In other applications like dielectric loaded horns and waveguides the use of dielectric inside them controls the excitation of various modes and thus the performance of the horns. Hybrid and multimode horns are examples that can improve the horn performance for reflector feed applications. Similarly, dielectric resonator antennas can control and improve the radiation performance by controlling the excitation and the phase of the wave propagating through them. Dielectrics being non‐conducting can also be used to insulate and, thus, isolate the antennas from living tissues, in medical treatment and studies. Large permittivity of some dielectrics reduces the signal wavelength and in areas of small antennas can be used to reduce the antenna dimensions. Finally, the dielectric permittivity also influences the wave impedance and can be used to match the impedance of antennas to the radiation media and enhance their gain. This article provides a brief review of some of these applications.
