Prestar oídos al poema Escucha y afectividad en la poesía argentina reciente
Authors: Moscardi Matías
Published: July 2023

En el presente artículo, propongo un recorrido a partir de cuatro escenas en las que se articulan distintas relaciones entre escucha y afectividad: el odio, el amor, la política y la alteridad. Cada apartado pone en foco distintos libros de la última década: Odio a la poesía objetivista, de Francisco Garamona; Vos ahora voz, de Franco Rivero; Sequía y Una bomba nos está matando a todos, de Gabriel Reches; y Martes dedo, de Alfonsina Brión. Mi objetivo es analizar el funcionamiento solidario entre escucha y afectividad a través de los efectos formales y compositivos sobre los textos. Como hipótesis, parto de la idea de que la escucha marca en los poemas una forma de relación con el otro. Metodológicamente, retomo los trabajos de Florencia Garramuño y Luciana di Leone sobre poesía y afectividad. A su vez, me remito a las teorías de la escucha esbozadas por Jean-Luc Nancy y Peter Szendy. A modo de aporte al campo específico de la crítica de poesía argentina, si bien el artículo propone un recorrido por libros puntuales, la problemática planteada podría pensarse de manera transversal como una línea de composición posible para la poesía del presente.
La identidad y otras razones para quemar París: París y el odio de Matías Alinovi
Authors: Escobar-Jiménez Christian
Published: July 2023

Este artículo analiza la segunda novela del escritor argentino, Matías Alinovi, París y el odio, publicada en el año 2016. El trabajo toma como eje central de estudio el problema de la identidad y la relación entre París, lo argentino y lo latinoamericano. En su primera sección, el trabajo expone brevemente el surgimiento de la idea de América Latina como una construcción francesa por oposición a los intereses norteamericanos, así como la importancia de París y lo francés para América Latina. Después, el artículo toma tres puntos de referencia de la novela en cuestión para discutir las temáticas de París y la identidad. En primer lugar, el personaje de Bianco, un trasunto del escritor argentino Héctor Bianciotti; en segundo lugar, la relación de la novela con la París construida por Cortázar en su célebre Rayuela; y, en tercer lugar, la identidad latinoamericana vista desde París a través de la figura de Atahualpa Yupanqui. El artículo incluye referencias a una entrevista realizada al propio autor de la novela sobre estos temas.
Un recorrido por la ciudad negada: revistas digitales y nuevos sujetos en La Habana de principios del nuevo siglo
Authors: Maccioni Laura
Published: July 2023

A partir de la pintura Ciudad negada (2016), del artista plástico René Francisco Rodríguez, este trabajo propone un análisis de dos revistas digitales publicadas en La Habana durante la primera década del nuevo siglo: Cacharro(s) (2003-2005) y 33 y 1/3 (2005-2009). El artículo examina los modos en que estos e-zines, precursores en el campo de las revistas literarias virtuales, trastocaron las condiciones o reglas de aparición de los sujetos (Rancière, 1996, p.45), haciéndole lugar a las partes negadas o sin-parte en la vida pública. Asimismo, el análisis se detiene en la estrategia de “aligeramiento” del peso de los relatos identitarios y la tradición nacional que estas revistas llevan a cabo para complejizar las figuras de lo común, estrategias que las singularizan respecto de sus antecesoras en papel.
Entre La Habana revolucionaria y La Habana distópica. Representaciones de la ciudad en el cine cubano
Authors: Lastre Reynaldo
Published: July 2023

Este ensayo analiza la forma en que la representación de La Habana en el cine cubano proyecta relaciones económicas y sociales de sus habitantes a través del tiempo. Para hacerlo, elijo tres filmes realizados en tres momentos diferentes en el contexto posterior a 1959. De esa forma, mi análisis entra en diálogo directo con las políticas públicas y las estrategias de conservación y desarrollo del espacio urbano dentro del periodo revolucionario. Primero, analizo la representación de la Habana en Memorias del subdesarrollo (Tomás Gutiérrez Alea, 1968), en donde la ciudad funciona como intermediaria entre la revolución y el intelectual protagonista durante los primeros años del proceso. Después me detengo en Buscándote Habana (Alina Rodríguez, 2006), corto documental donde se exploran los espacios marginalizados de la ciudad a través del testimonio de migrantes cubanos ilegales. Finalmente, reviso la reelaboración de una Habana distópica en el corto de ficción Tundra (José Luis Aparicio, 2021).
El paisaje portuario, repositorio de la historia habanera
Authors: Leal del Ojo de la Cruz Yaneli
Published: July 2023

Desde la perspectiva del paisaje se pretende ofrecer una valoración patrimonial del puerto habanero, entendiendo que constituye un paisaje histórico cargado de significados transcendentales para La Habana. El reconocimiento de la herencia cultural de la bahía y de los vínculos históricos establecidos con la ciudad y su población, resultan clave en la regeneración de sentimientos afectivos y en la conservación de la esencia del lugar. De ahí que sea fundamental su valorización patrimonial desde una visión en sistema que analice el proceso histórico, el contexto físico, las manifestaciones materiales e inmateriales, sus interrelaciones, los vínculos con la ciudad y su proyección hacia el mundo. Para la elaboración de este artículo se utilizaron métodos teóricos y empíricos de análisis cualitativo en correspondencia con las prácticas habituales de estudio del paisaje, la observación del sitio y el análisis de documentos e imágenes.
La Habana en el siglo XXI: una ciudad leída, generada, desbordada
Authors: Viera Katia
Published: July 2023

Este trabajo se propone indagar en las lecturas, referentes, pautas y resortes del canon literario cubano que algunos narradores de la Generación Cero han realizado/usado/identificado para configurar La Habana en sus obras. Se parte de la hipótesis de que aquellos referentes y lecturas son actualizados, retomados y deconstruidos por parte de esta generación al momento de expresar su personal relación con/interpretación de la ciudad y aunque un conjunto de recientes escrituras producidas en Cuba quiera incendiar el archivo, muchas de ellas aún continúan nutriéndose de la tradición. De este modo, el presente texto dedica una primera parte a visibilizar las negociaciones con el canon y una segunda que describe el diseño trazado por parte de algunos autores del siglo XXI de su o sus ciudades desde la experiencia, las lecturas y la afectividad.

Kekerasan terhadap anak dan perempuan merupakan salah satu bentuk pelanggaran hak asasi manusia. Berbagai bentuk kekerasan kepada perempuan terus berkembang dalam kehidupan masyarakat, mulai dari kekerasan nonfisik atau verbal dan fisik. Hal inilah yang kemudian membuat masyarakat mendorong pemerintah untuk menetapkan Undang-Undang yang berlaku secara luas dalam rangka menghapuskan berbagai kekerasan. Rancangan Undang-undang Penghapusan Kekerasan Seksual berulang kali masuk dalam Program Legislasi Nasional, hingga kini belum terbentuk Undang-Undang yang sah sebagai tonggak penegakan keadilan yang menjadi dasar dalam memberikan sanksi pada pelaku dan memberikan perlindungan kepada korban. Oleh karena itu, metode pada kegiatan pengabdian ini yaitu penyampaian materi oleh narasumber kemudian di akhir kegiatan peserta membuat poster dengan aplikasi canva yang berisi tentang informasi UUTPKS. Dengan begitu, kegiatan pengabdian kepada masyarakat memiliki harapan untuk mencegah segala bentuk kekerasan seksual. Hal ini dilakukan dengan membuat dan menyebarkan poster melalui sosial media agar seluiruh masyarakat Kabupaten dan Kota Kediri sadar terhadap bahaya tindak kekerasan seksual. Khususnya juga mengetahui cara pencegahannya agar Kabupaten dan Kota Kediri dapat menjadi kota nol TPKS. Oleh sebab itu, perlu adanya sosialisasi UUTPKS kepada lapisan masyarakat agar dapat menjadi proteksi diri bagi anak dan perempuan.

Reflexiók a jogegységi panasz kezdeti működésére, különös tekintettel az első indokolatlan eltérést megállapító jogegységi panasz határozatra
Authors: Csibor Ferenc
Published: July 2023

A Kúria jogegység, vagyis az egységes ítélkezési gyakorlat biztosításában legmagasabb bírói fórumként betöltött alkotmányos szerepében jelentős változás következett be 2020-ban. A korlátozott precedensrendszer hatályba lépése által a jogegységet immáron már első sorban a Kúria Bírósági Határozatok Gyűjteményében közzétett határozataihoz társuló kötőerő biztosítja. A rendszernek egy fontos elemét adja a jogegységi panasz elnevezésű új jogorvoslati eljárás. Jogegységi panasszal lehet élni a kúria felülvizsgálattal tovább nem támadható határozatával szemben, amennyiben a határozat eltérést tartalmaz a Kúria közzétett határozatától. Indokolatlan eltérés esetén a Jogegységi Panasz Tanács a határozatot hatályon kívül helyezi, és a Kúriát új eljárásra és új határozat hozatalára utasítja, valamint kimondja a bíróságokra kötelező jogértelmezést, ezzel előmozdítva a jogegységet. A tanulmány célja behatóbban megvizsgálni a legelső olyan jogegységi panasz ügyet, amikor a Jogegységi Panasz Tanács indokolatlan eltérést állapított meg. A vizsgálat kiterjed az alapügy tényállásának bemutatására, továbbá a jogegységi panasz lényegét adó jogkérdésre, miszerint az Európai Unió Bíróságának előzetes döntéshozatali eljárásban hozott határozata megalapozhat-e perújítást. A jogkérdés bemutatásánál külön figyelmet kap az előzetes döntéshozatallal foglalkozó nemzetközi uniós szakirodalomban, a perújítással kapcsolatban pedig a hazai eljárásjogi szakirodalomban kialakult álláspontok ismertetésére.
Önkormányzati autonómia – alkotmányos alapjog vagy személyiségi jog?
Authors: Nagy Sándor
Published: July 2023

A helyi önkormányzatok lényege az autonómiában, önrendelkezésük szabad gyakorlásában rejlik. Elemei kezdetben alkotmányi szinten védett alapjogok voltak, mára azonban csupán hatáskör csoportokká váltak – fókuszban a helyi közfeladatokkal –, amelyet számos alkotmánybírósági döntés is lefektetett, új alapokra helyezve a helyi önkormányzást. Az alkotmányjog mellett a polgári jogi jogviszonyokban is sajátos helye van az önkormányzatoknak, ugyanis kettős szerepet játszanak mind közjogi, mind magánjogi értelemben véve egyaránt. Miként értelmezhető az önkormányzati autonómia? Alkotmányos alapjogként vagy egyfajta különleges személyiségi jogként fogható fel? Noha a Magyarország helyi önkormányzatairól szóló 2011. évi CLXXXIX. törvény – ellentétben az Alkotmánnyal – az Alaptörvény 32. cikk (1) bekezdésében meghatározott feladat- és hatáskörök jogszerű gyakorlását alkotmánybírósági és bírósági védelemben részesíti, az szinte látszólagos. Az autonómia sérelmének bekövetkezése esetén jelenleg nincs olyan rendszer, ami hatékony védelmet nyújthatna a központi kormányzat ellensúlyaként működő szervezeteknek. Éppen ezért, amennyiben az autonómiát speciális személyiségi jogként interpretáljuk, úgy megnyílhat egy további út a helyi önkormányzatok jogvédelmének biztosítása vonatkozásában. A tanulmányban főként alkotmánybírósági döntéseken keresztül – jogdogmatikai módszert alapul véve – keresem a választ a fenti kérdésekre.

Authors: Atef Mahinour Mohamed , Shaltout Amany Ahmed Mohamed , Zamzam Maha Lotfy , Soliman Sharehan Hassan
Published: July 2023

Background: Recently, peripheral blood inflammatory biomarkers such as neutrophil-lymphocyte ratio (NLR) have been identified for their prognostic role in many types of cancers. Elevated NLR was associated with poor prognosis & increased mortality rates. This study assessed the predictive value of pretreatment NLR in non-metastatic breast cancer.Objective: To assess the role of pretreatment NLR in non-metastatic breast cancer and their effect on prognosis in terms of 5 years disease-free survival and overall survival.Methods: This retrospective cross-sectional study was conducted in Suez Canal University Hospitals in Ismailia, Egypt. 105 patients with pathologically proven breast cancer were recruited from January 2015 to December 2016. Patients & tumor characteristics were collected from medical records. Five-year overall survival & disease-free survival were analyzed.Results: Mean patients’ ages were 47.82 ± 11.65. The age ranges were between 25 & 78 years. There was no statistical significance between patients with low & high pretreatment NLR in terms of patients’ characteristics & tumor variables. With the ROC curve, the cut-off points for NLR were 1.65 & 1.55 for DFS and OS, respectively. In terms of patients’ DFS & OS, no statistically significant difference was found between non-metastatic breast cancer patients with low & high NLR (plog­-rank = .357 and .236, respectively). No statistically significant difference was found between patients with low & high pretreatment NLR in the period of five years OS & DFS.Conclusions: Pretreatment NLR is an inflammatory biomarker that might affect patient prognosis and survival. Further research is required to confirm the prognostic significance.
Use of Translated Saudi Folk Narratives to Improve Reading and Speaking Skills of Saudi EFL Learners
Authors: Yousif Abubaker , Eligedi Rajkumar , Bandu Sasidhar
Published: July 2023

The present study aims to explore how the use of translated Saudi folk narratives could help improve Saudi EFL learners' reading and speaking skills. (41) EFL elementary-level students from Prince Sattam bin Abdulaziz University were selected for this study to identify and assess the influences of the translated Saudi folk stories in enhancing the reading and speaking skills of Saudi EFL learners. An experiential teaching method using selected translated Saudi stories into English was adopted. The preliminary findings in the pre-intervention stage have shown that the students were neither motivated to read the content nor speak in English as the students encountered some kind of difficulties in comprehending the translated stories. The post-intervention results demonstrated that the students were motivated to read the Arabic stories in English. It also showed that the students were engaged to speak about Saudi / Arabic oral stories and culture. The effect of using Saudi-translated stories was observed in improving the reading and speaking skills of EFL Saudi learners. Thus, the study concludes that it is essential to use the translated Arabic folk stories as supplementary teaching material in the EFL reading and speaking classes. It also suggests that we need to translate Saudi folk stories into English for the benefit of Arabic and non-Arabic readers and speakers.
The Impact of Vocabulary Size on the Receptive Skills of Saudi EFL Learners
Authors: Alshehri Ahmad
Published: July 2023

The present study aimed to investigate the impact of vocabulary size on Saudi EFL learners’ reading and listening skills. Thirty-eight undergraduate Saudi EFL learners participated in the study. The study tools consisted of vocabulary size test (VST) developed by Nation and Beglar (2007). The test was developed to provide a reliable, accurate, and comprehensive measure of a learner’s vocabulary size from the 1st 1000 to the 14th 1000-word family of English word-level tests. A paid reading and listening comprehension tests were used. Both tests were obtained from ETS, TOEFL official application. The results revealed that the vocabulary size of the Saudi EFL learners in the tertiary stage was 2790 words. Furthermore, the study found a positive relationship between the scores of the vocabulary test levels and the score of the reading and listening test. This indicates that a higher level of performance in the vocabulary test may lead to a higher level of performance in the reading and listening test, and these relationships were statistically significant at the level of 0.01. Because of this, it was recommended that teachers and learners use different approaches and styles for teaching and learning vocabulary.
Formulaic Language Use by Learners of English in Interlanguage Communication
Authors: Pan Zhaoyi
Published: July 2023

This study investigated the use of formulaic language, in the form of four-word lexical bundles, by Thai learners of English as a second language (ESL) at various levels of English proficiency during interlanguage communication. The investigation focused on two aspects: the frequencies and pragmatic functions of the four-word lexical bundles. A total of 120 Thai ESL learners participated in the study, ranging from basic to intermediate and advanced English proficiency levels. In terms of frequency, a list of the most frequently used four-word lexical bundles by Thai ESL learners at each level was examined. Results showed that learners at higher English levels used less formulaic language in interactions than those at lower levels. Two similar four-word lexical bundles, centered on "I don't know" and "I think," were used by Thai ESL learners at all three English levels. The functional analysis demonstrated that Thai ESL learners at all three English levels used formulaic language to assert group identity as a device for social interaction and as a device for memory limitations to buy more time and process shortcuts. The function of asserting a separate identity was not used by intermediate-level Thai ESL learners. Furthermore, the function of processing shortcuts was used less at the advanced level than at the basic level. The findings of this study indicate that Thai ESL learners use formulaic language differently at different English proficiency levels. Therefore, formulaic language used by ESL learners in spoken English discourse should be further investigated.

Published: July 2023

Research methodology courses have become an important requirement for students in many undergraduate programs in Saudi Arabia. The purpose of this case study is to explore students’ perceptions of using collaborative learning (CL) in a research methodology course. This course is an undergraduate-level course that is taught in the Department of English Language and Translation at Saudi Electronic University (SEU) in a blended learning environment. Also, this study aims at understanding the effects of introducing group projects into the curriculum on students’ learning experiences from their points of view. In addition, this research sheds light on how students perceived the distribution of workload within groups. The current study employed qualitative methods to collect data by distributing a qualitative questionnaire with open-ended questions. The data were collected from 137 students enrolled in three different branches of SEU in Riyadh, Jeddah and Dammam. The data were analyzed by using thematic analysis to provide a rich description and generate themes. The findings of this study revealed that the majority of the participants believed that CL in a blended learning environment had a positive impact on their learning experience. The participants perceived CL as both beneficial and challenging. In addition, most of the participants felt that the workload was distributed equally among the group members. Based on the findings, recommendations are discussed to promote effective CL in higher education.

Published: July 2023

This research reveals students' readiness and perceptions of online learning post the COVID-19 pandemic. Online learning has gained significant popularity during the COVID-19 pandemic. This learning method offers flexibility and convenience for students, however now that learning in higher education institutions has returned to normal, how students' perceptions of online learning are fully debated in this study. Three hundred and eight students from local universities in Indonesia took part in a quantitative study to explore the satisfaction and effectiveness of online learning. This research is a cross sectional study completed by making an association between various parameters using an independent t-test and one-way ANOVA. The findings report that most of the students are dissatisfied with online learning and only the facts find that it is effective for their learning. It is based on the facts that both genders are equally ready for online learning after the post Covid-19 pandemic. It is proved by Welch test indicating that there was no significant difference in readiness for online teaching between gender (t= 0.089, p = 0.935). There is no significant difference in gender in their perception on the effectiveness of online learning. A negative t-value indicates (t = -0.45, p = 0.653). And there is no significant difference among the students from different faculties in their readiness for online learning based on one-way ANOVA test showing that p<0.05 level on the effectiveness of online learning post-covid [F(5, 127) = 3.714, p =0.004] and the readiness for online learning was not statistically different between faculties [F(5, 127) = 0.827, p =0.533]. Refer to online learning. The study concluded that a fully online mode may not be suitable for all types of learners. Instructors and institutions need to recognize these issues and provide appropriate supports and solutions to improve the effectiveness of online education.
Breast Cancer Incidence, Mortality, and Cost in Adolescent Idiopathic Scoliosis Patients and the Role of Low Dose Biplanar Radiography
Authors: Farivar Daniel , Skaggs David L. , Gabriel Keith , Illingworth Kenneth D.
Published: July 2023

Introduction:

Patients with adolescent idiopathic scoliosis (AIS) are susceptible to high doses of radiation from radiographs. The purpose of this study was to examine the future cost of radiation-induced breast cancer in patients with AIS and its potential financial and mortality impact.

Methods:

A literature review identified articles relating radiation exposure in patients with AIS to increased risk for cancer. Based on population statistics and breast cancer treatment costs in the year 2020, the financial impact of radiation-induced breast cancer and the estimated number of additional deaths per year due to breast cancer for patients with AIS were calculated.

Results:

The US female population in 1970 was 205.1 million. Based on a prevalence of 3.0%, an estimated 3.1 million patients had AIS in 1970. With an incidence of breast cancer in the general population of 128.3/100,000 and a standardized incidence ratio of 1.82—2.4 for breast cancer in patients with scoliosis, there will be a 3,282 to 5,603 patient increase in radiation-induced breast cancer in patients with scoliosis over the general population. With a projected base cost of $34,979 per patient for the first year of breast cancer diagnosis in 2020, the cost of radiation-induced breast cancer will be 114.8 to 196.0 million dollars per year. Using a standardized mortality ratio of 1.68 for scoliosis radiation-induced breast cancer, there will be an expected increase in deaths of 420 patients due to breast cancer presumably secondary to radiation exposure in the evaluation and treatment of AIS.

Conclusion:

The estimated radiation-induced breast cancer financial impact in 2020 will be between 114.8 and 196.0 million dollars per year, with an increase in deaths of 420 patients per year. Low-dose imaging systems reduce radiation exposure by up to 45 times while maintaining sufficient image quality. New low-dose radiography should be used whenever possible with patients with AIS.

Disconnected: Electronic Patient‐ReportedOutcome Measure Collection In Orthopaedic Patients at an Urban Safety-Net Hospital
Authors: Tucker Nicholas J. , Shah Ananya , Mauffrey Cyril , Hammerberg Mark , Parry Joshua A.
Published: July 2023

Introduction:

Collection of patient-reported outcome measures (PROMs) in orthopaedic patients at safety-net hospitals is challenging. The purpose of this study was to evaluate the success of electronic PROM (E-PROM) collection in this setting.

Methods:

A retrospective review identified 207 consecutive orthopaedic patients undergoing 77 elective arthroplasty procedures and 130 trauma procedures. E-PROMs were collected through automated e-mails from an online patient engagement platform (PatientIQ) at 2 weeks, 6 weeks, and 3 months postoperatively. Patients with trauma received the percentage of normal Single Assessment Numerical Evaluation (SANE) and Patient-Reported Outcomes Measurement Information System–Physical Function (PROMIS-PF). Arthroplasty patients received the Hip/Knee SANE, Hip/Knee Disability and Osteoarthritis Outcome Score-Joint Replacement (HOOS Jr/KOOS Jr), PROMIS Global Physical Health (PROMIS-G-PH), and Veterans RAND 12-Item (VR-12) Health Survey.

Results:

Compared with patients with trauma, arthroplasty patients were older (median difference 18.0 years; 95% confidence interval [CI] 12.0-22.0; P < 0.0001), more likely to be Hispanic/Black (proportional difference 16.9%; CI 2.8-30.3%; P = 0.02), more likely to have noncommercial or no insurance (proportional difference 34.0%; CI 23.2-43.0%; P < 0.001), and did not differ in Area Deprivation Index or E-PROM completion at each time point. E-PROMs were completed at 2 weeks, 6 weeks, and 3 months by 25.1% (52 of 207), 24.6% (51 of 207), and 21.7% (45 of 207) of all patients, respectively. Trauma and arthroplasty patients had a similar rate of partial E-PROM completion. Patients who completed 3-month E-PROMs were less likely to be Hispanic/Black (PD −16.4%; CI −31.0 to −0.2%; P < 0.04); less likely to have noncommercial/no insurance (PD −20.0%; CI −35.5 to −4.5%; P = 0.01); and did not differ in age, sex, Area Deprivation Index, or procedure type.

Discussion:

The low collection rate of E-PROMs from orthopaedic patients at safety-net hospitals should be weighed against their costs. E-PROM collection may exacerbate disparities in PROM collection among certain patient populations.

The ongoing inflammatory process in COVID infection is reported to cause acute cardiac injury either due to direct cytotoxicity or oxidative stress injury to myocytes. Hypercoagulability and endothelial dysfunction are the two main events resulting in the transient thrombotic process. Objective: To assess the coronary artery occlusion in COVID infected patients presenting with ST-elevation myocardial injury. Methods: A descriptive case series study was conducted on 52 patients presenting with ST-elevation myocardial infarction along with COVID infection. Data was collected regarding demographic profile, Troponin levels, COVID PCR, changes in ECG, Echocardiographic findings and coronary arteries were assessed angiographically. Data were analyzed using SPSS software and various percentages were calculated. Results: Of all the 52 patients studied, 46 patients (88%) tested positive for COVID -19 on RT-PCR done via nasopharyngeal swab. Other 6 patients tested negative initially but they had findings on their CXR and HRCT suggestive of interstitial pneumonia. All the patients were in age group 30-60 years with 32 patients (62%) being males and 20 being females (38%). None of the patients previously had any history of angina or myocardial infarction. Inflammatory markers were raised in about 43 patients (82.7%). ECG showed ST segment elevation in anterior leads in 35 patients (67%) and in inferior leads in 9 patients (17%) and in lateral leads in 2 patients (3.8%). Qualitative Troponin I test was positive in all the patients, whereas, about 41 patients (78%) had Quantitative Troponin I test in high probability range. About 50 patients (96%) had Ejection Fraction greater than 45% and normal segmental wall motion analysis. The coronary arteries were reported to be normal or recanalized in 40 patients (76%) and mild-moderate disease in single or two vessels are present in rest of the 12 patients. None of the patients had shown culprit artery severe disease or clot burden on angiograms. Conclusions: Acute Cardiac injury in previously asymptomatic patients may be related to the pro-thrombotic state created by COVID-19 infection resulting in endothelial dysfunction and mimicking ST-elevation myocardial injury raising Troponin levels indicated by raised D-Dimers and CRP level. The auto-recanalization of the coronary arteries and normal echocardiographic findings, are good prognostic factors for the post cardiac injury rehabilitation.

APPLICATION OF DEPRECIATION NET PRESENT VALUE AND INTERNAL RATE OF RETURN IN ENGINEERING PROJECTS A BRIEF LITERATURE REVIEW
Authors: Wangchuk Pema
Published: July 2023

The Net Present Value (NPV), Internal Rate of Return (IRR), and Depreciation Methods are employed in most engineering projects to visualize the true potential of Return on Investment (ROI) in today’s capital investment world. Most previous studies have appreciated and indicated the usefulness of each method in determining economically feasible projects. However, some previous studies have applied all methods without a proper distinction between budgeting and accounting concepts and lacked insights into various situations under which each method has differed. This paper aims to explore the circumstances in which all methods differ to determine the most economically and optimal project alternatives. It describes a thematic literature review of the past 17 articles like the peer-reviewed conference and journal articles published from 1969 through 2021. The articles with citations have been randomly selected to analyze the data. The results indicate that the three methods are commonly used in all engineering projects under certain conditions. It concludes that NPV and IRR are capital budgeting methods based on discounted cash flow methods while depreciation is the accounting method based on non-cash discounted methods. The results also demonstrate that different depreciation methods are also employed throughout the project evaluation process to determine the best project alternatives. For an engineer to produce the results and make effective investment decisions, estimating the cost, predicting the savings, and acclimatizing to the budgeting and accounting concepts are crucial under each method.

Abstract: Porous concrete for low-impact development has long been studied for the improvement of urban stormwater management. However, the porous concrete made using Recycled Concrete Aggregate (RCA) is still lacking, particularly concerning its strength and infiltration rates. Therefore, this paper aimed to design porous concrete using RCA with optimum infiltration rate without compromising the strength. To fulfill this aim, a laboratory study evaluating the strength and infiltration characteristics of a porous concrete mix is presented. From the mixed design 1: 0.4: 3.6 (Portland Pozzolana Cement (PPC): natural sand: natural coarse aggregate), Natural Coarse Aggregate (NCA) is partially replaced by RCA in the interval of 0%, 15%, 30%, and 45% to find the optimum infiltration without compromising the strength. The 10 mm aggregate is used as it was recorded for the highest compressive strength after curing for 28 days. With the increase in the addition of RCA, the compressive strength decreases whereas the infiltration rate increases. From the comparative study of infiltration rate and compressive strength, 30% replacement of NCA with RCA in the ratio of 1:0.4:1.08:2.52 (cement: fine aggregate: RCA: NCA) is found to give the most satisfactory result with infiltration rate and compressive strength of 9737 mm/hr and 8.67 MPa respectively. The water quality test is conducted to evaluate whether the porous concrete detention system can reduce the pollutants from the surface run-off. The pH and acidity parameters are considered to check the quality of stormwater. Stormwater after infiltrating through the prototype becomes basic in nature.

Authors: Chhetri Indra Bahadur
Published: July 2023

Like many other countries, Bhutan is also experiencing rapid trend of urban expansion mainly due to out-migration from rural to urban areas particularly in capital city, Thimphu. This study focuses on the dynamics of urban expansion, evaluating urban growth and land consumption pattern of Thimphu, using multi-temporal Landsat images during the year 1990-2018. The main aim of the study is to perform supervised classification to classify built-up area, green area, bare-land and others (water bodies, agricultural lands, etc…) and to perform a change analysis from the viewpoint of increasing the built-up areas (man-made structures) and decreasing in green and open spaces. Moreover, the study also highlights how has the land consumption pattern of the region changed over the years. The findings of the study confirmed that the Thimphu city has its built-up areas increased during 1990-2018 with net growth of 4.63 km2 (106.19%). The urban area was 4.36 km2 in 1990, 5.80 km2 in 2000 (33.03% growth), which increased to 7.24 km2 in 2013 (24.83% growth) and 8.99 km2 (24.17% growth) in 2018. The study also showed that there is decrease in land consumption between 1990-2018. In 1990, land consumption was 155.65 m2 per person which decreased to 78.48 m2 per person in 2018. This decrease in land consumption indicate that the city is experiencing increased densification between the years 1990-2018. The classifier performance evaluation was done using overall accuracy and kappa coefficient. The classification produced an overall accuracies ranging between 78.74% to 90.46 % and overall kappa statistics between 0.72 to 0.87 for all years indicating classification accuracy of moderate to substantial accuracy.

Published: July 2023

The building sector in Bhutan is responsible for 42% of total energy and consumes 242,916 TOE of thermal energy. The maximum thermal energy was used for space heating. As per the studies conducted on the energy efficiency of the buildings in Bhutan, the buildings are found to be the worst performance in terms of thermal and airtightness. Without the proper insulation, lack of choice of the building materials as per the climatic conditions and lacks of awareness in the society about the green building practices has led to poor indoor quality of life. Buildings located inthe high region are found to be uncomfortably cold during winter months.This research focuses on studying the thermal performance of different building typologies. The main findings of this research were on enhancing indoor thermal comfort and reducing heating energy demand by the incorporation of passive measures. The results were achieved by simulating the buildings in EnergyPlus software using the data collected from questionnaires and field surveys. The simulation results showed that among the investigated buildings, a concrete hollow block wall located at Kabesa has the less comfort hour of 15% at the existing condition. When passive interventions were incorporated into the building, the thermal comfort hours were achievable up to 32% with the load reduction potential of 65%.As for the traditional house with the adobe brick wall and timber wall at Changdagang, had more comfort hours than the building located at Kabesa. With the different set of passive intervention, it was found that comfort hour of 38% to 41% and load reduction of 25.9% can be achieved for the building with adobe brick wall and timber wall respectively. Whereas for stone masonry with cement mortar and RCC framed structure located at Begana and Langdru had a thermal comfort hour of more that 30%. However, RCC framed structure was reported to have huge demand for heating energy compared to stone masonry with cement mortar. The passive intervention prepared for RCC and stone masonry had the potential to achieve 41%-57% of thermal comfort hours. The results from all the investigated buildings revealed that the inclusion of passive design could improve indoor thermal comfort and can achieve a reduction in heating energy demand.

In this research, an approach for predicting wind energy using machine learning has been explored. An indirect method has been adopted. Predicting wind speed at first using the hourly weather data and combining that predicted wind speed with the power curve of considered wind turbine prepared by the companies. This research aims to develop a generalized machine learning based wind power forecasting model for Bhutan. Thus, hourly weather data for the year 2018 and 2019 of 300kW On-grid Wind Farm at Rubesa was used to train the base model. Meanwhile, the trained base model was tested against the weather data sets for the selected sites namely Gaselo and Dagana. A Random Forest Regression machine learning algorithm was used in this research. The developed base model has five input variables which are time, temperature, global horizontal irradiance, relative humidity, and pressure, while the target is wind speed. The R- squared values, Root Mean Square Error (RMSE), and Mean Absolute Error (MAE) for the developed base model were found to be 0.88, 0.40 and 0.30 respectively. Energy output in the wind turbine was calculated via the predicted wind speed and power curve prepared by the wind turbine companies. The calculated energy output could shape the considered theoretical power curve. The power curve considered in the present research is 300kW On-grid Wind Farm at Rubesa, Wangdiphodrang.
