The Impact of Credibility Attributes on Consumer Intention to Adopt Information on Social Networking Sites
Authors: Elsantil Yasmeen , Eid Riyad , Bedair Khaled
Published: March 2022

This study examines the effect of consumers’ perceived credibility of information on SNS on their attitude and intention to adopt this information in the Arab world. The study adopted a quantitative research approach using a survey questionnaire conducted among 317 individuals. Structural equation modelling was conducted. The results highlighted that there are positive direct effects of authority cues, expertise, trustworthiness, social identity and argument strength on perceived credibility. Although both authority cues and transparency have non-significant direct effects on perceived credibility, they have positive direct effects on attitude and indirect effects on intention via attitude. Finally, the positive impact of credibility on intention is mediated by attitude. This study contributes to the literature on the credibility of information on SNS and its effect on consumers’ intention to adopt it.

The sample consisted of 4703 Facebook posts from the top ten most popular Indian and global higher education institution pages. The platform engagement options were used to categorize audience reactions, while structural attributes were examined in accordance with applicable theory using a negative binomial regression model. Factor analysis and descriptive metrics were used to evaluate theme efficacy. The findings highlight the significance of developing a comprehensive assessment of content structural efficiency. The paper presents a number of evidence-based recommendations for projecting and estimating content performance. This study adds to the body of knowledge by first merging the content subject with its structural parts. Previously, the content theme was thought to be a qualitative unit.
Does Personality Influence the Frequency of Online Purchase Behavior?
Authors: Ayob Abu H. , Wahid Siti Daleela Mohd , Omar Nor Asiah
Published: March 2022

Scholars have acknowledged the influence of personality traits on individuals’ behavior. However, the effect of personality on (repetitive) online purchase behavior remains under-explored. This is a considerable deficit in knowledge because a marketing paradigm has shifted its interest to examine strategies for attracting new buyers as well as retaining existing customers. To further the understanding of this issue, this paper attempts to examine the relationship between the Big Five personality traits — openness, conscientiousness, extraversion, agreeableness, and neuroticism — and the frequency of online purchases among 386 university students in Malaysia. Through a Structural Equation Modelling analysis, we found that extraversion, agreeableness, and neuroticism were positively related with the frequency of online purchases. In contrast, openness and conscientiousness showed no significant effect. Overall, this research suggests that marketers should target buyers with certain personality traits because they are likely to use online platforms more often for purchasing items.
Toward a Significant E-Voting Adoption Model
Authors: Alomari Mohammad Kamel , Khan Habib Ullah
Published: March 2022

Technology, through internet use, has changed how citizens interact and communicate with their governments. However, in any society, a proportion of people cannot access this type of interaction due to digital divide issues. Consequently, this study developed a model by investigating the impact of digital divide factors on technological system adoption, that is, e-voting, mainly in Jordan, a developing country. The model proposes that four digital divide factors, namely age, education, income, and internet use, directly influence citizens' intentions to use an e-voting website. A survey study of 267 Jordanian citizens (and internet users) explored whether the digital divide e-voting adoption model was significant. Analysis of the collected data showed the model's significance for exploring the digital divide's impact on citizens' intentions to use an e-voting website. This study, with its focus on parliamentary elections, is one of the few to examine how the digital divide influences e-voting adoption in the Middle East. Future research will focus on municipality elections.

Customer Capabilities and Value Co-Creation Practices in Self-service Technologies: Insights from Commercial Banks in Sri Lanka
Authors: Galdolage B. S. , Rasanjalee R. M. K. S.
Published: March 2022

Many service encounters that service employees previously managed are being transformed into technology-enabled self-service interactions, including those in the banking sector. However, scholarly work has not paid sufficient attention to studying Self-Service Technologies (SSTs) in service encounters. Thus, the purpose of this study is to investigate the practices that customers engage in co-creating value with SSTs in the banking sector, along with prerequisite capabilities that customers must possess to complete successful service transactions. A qualitative approach was used, conducting semi-structured interviews with 50 banking customers who use SSTs in the Western Province, Sri Lanka. The study found seven key-value co-creation practices and five types of capabilities an individual should possess to use banking SSTs. The findings contribute to the existing literature by addressing the prerequisites and practices of customer value co-creation in banking SSTs, which have received sporadic attention.
Effect of Financial Development and Foreign Direct Investments on Economic Growth in SAARC Countries: A Panel ARDL Approach
Authors: Vandana . , Singh Shveta
Published: March 2022

This paper explores the impact of financial development and foreign inflows on economic growth in the following SAARC nations: Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka from 2006 to 2019. The econometric tool used is the Autoregressive Distributed Lag Model (ARDL) in panel settings and Pedroni Cointegration test to observe the connection between financial development, foreign influx, and economic growth. Findings from the Pedroni panel cointegration test showed that the variables are cointegrated in the long run. Pooled Mean Group (PMG) estimates suggested that broad money positively affects economic growth while gross savings have an undesirable influence on economic growth. However, the influence of domestic credit was negative but insignificant. Further, the influence of external influx on output growth is found to be adverse. The findings suggested that the economic policies of these countries should be defined by considering the financial sector of these countries.
Modified Spear flap for the reconstruction of a full-thickness defect of the nasal ala
Authors: Cecchi Roberto , Savarese Imma
Published: March 2022

Various options are available for the reconstruction of full-thickness defects of the nasal ala with different advantages and disadvantages, but none are fully satisfactory. We present the case of a 57- year-old man with a recurrent basal cell carcinoma of the right nasal ala and nearby cheek and upper lip. Tumour clearance was achieved after two stages of ‘fresh/frozen’ Tübingen technique, resulting in a 2.0×2.0 cm full-thickness defect of the lateral right ala. The wound involved the alar rim, groove and adjacent check and upper lip. Reconstruction was successfully achieved with a nasolabial turnover flap (modified Spear flap) in a single stage. The surgical procedure and subsequent outcomes are illustrated. Our experience shows the effectiveness of the nasolabial turnover flap for a single-stage repair of full-thickness defects of the nasal area and adjacent tissue.

Authors: Pradeep Thanuja G. , Namrata Devappa , Thomas Anju Mary
Published: March 2022

Purpose:

The purpose was to study the proportion and risk factors for posterior capsular rent (PCR) in small incision cataract surgery in a teaching hospital.

Methods:

We conducted a retrospective observational study of all cases with PCR in small incision cataract surgery performed between November 2015 and May 2018. The medical records were analyzed and data were collected.

Results:

There were a total of 63 cases of PCR out of 4206 cases who underwent small incision cataract surgery with a 1.68% PCR rate. The mean age was 65.5 years and the male-to-female ratio was 2.15:1. There was no association between nuclear sclerosis, pupil dilatation, and pseudoexfoliation. Resident operated surgeries had a PCR rate of 1.96 compared to faculty operated surgeries which was 1.46. Three faculty surgeons accounted for 54.3% of the cases while the remaining ten surgeons accounted for 45.7% of the cases. Postoperative day 1 vision was low, with only 19% achieving >6/18 vision, and 54% of the individuals needed more than one topical drug and 61.5% were started on oral steroids.

Conclusion:

Surgeon- and patient-related factors are equally important in avoiding posterior capsule rent in cataract surgeries. Patient-related factors should be carefully assessed preoperatively on slit-lamp biomicroscope, so that surgeons are prepared for all the complications and visual morbidity limited. Surgeon factors also need to be looked into and efforts have to be made to limit them and thus ensure the right to vision to each patient.

Authors: von-Bischhosffshausen Fernando Barría , Andrighetti G Francisco , Rivera G Nicole , Sabando F Vezna
Published: March 2022

Diabetic retinopathy (DR) is the leading cause of blindness among working-age persons in high-income countries. A public system strategy was developed to improve screening, using telemedicine, automatic detection using artificial intelligence (A/I) and medical reporting. In the current work, we evaluated program efficiency.

Material:

We conducted a cross-sectional study using information from an institutional database of retinographies submitted to the A/I platform in 2019. With a positive test, a medical report was made using the international scale.

Results:

In 2019, 220,994 retinographies were reported, corresponding to 24.0% of diabetic patients. Around half (53.0%) of cases were discarded by A/I, being different in each regional health service. The medical analysis discarded diabetic retinopathy in 30.2% of exams, 11.5% had diabetic retinopathy, including 2.3% with risk of blindness, while 3.7% could not be evaluated.

Discussion:

The use of A/I allowed optimizing the medical resources, discarded 53% of cases, which helped in the screening of diabetic retinopathy. Coverage is still insufficient, and detection of macular edema must be improved.

La retinopatía diabética (RD) es la principal causa de ceguera en la edad laboral en países desarrollados. Se desarrollo una estrategia en sistema publico para mejorar el tamizaje, usando telemedicina, detección automática (I/A) e informe medico. En este trabajo, deseamos evaluar su eficiencia.

Material: Se realizó un estudio transversal de retinografías tributados a la plataforma de I/A, durante el año 2019. Se obtiene la información desde una base institucional. Con examen positivo se realiza un informe médico usando para graduar la escala internacional.

Resultados: En 2019 fueron tributadas 220.994 retinografias, que corresponde al 24,0% de los pacientes en control por diabetes. El 53% de los casos fueron descartados por la I/A, siendo variable en los diferentes servicios de salud regionales. El análisis medico descartó RD en el 30,2% de los exámenes, el 11,5% presentaba una RD incluyendo un 2,3% con riesgo de ceguera y el 3,7% no pudo ser evaluado.

Discusión: El uso de I/A permitió optimizar el recurso medico, descartando 53% de los casos ayudando en el tamizaje de una RD. La cobertura aun es insuficiente y se debe mejorar la detección de un edema macular.
Knowledge, attitude, and practice of the use of personal protective equipment and its psychological impact among Indian anesthesiologists during the COVID-19 pandemic
Authors: Avula Jyothi , Babu Anand , George Donae Elizabeth , Rai Sakshi , Sahajanandan Raj , Lionel Karen Ruby , Joselyn Anita Shirley
Published: March 2022

Background:

Anesthesiologists, with their skills and expertise at performing various aerosol-generating procedures such as tracheal intubation and extubation, tracheostomies, and bronchoscopy-guided procedures, serve as frontline workers during the COVID-19 pandemic. They are exposed to the risk of infection as well as highly stressful environments in the operating theaters and intensive care units. Appropriate knowledge, attitudes, and practices (KAPs) with regard to the use of personal protective equipment (PPE) will help mitigate some of this stress.

Materials and Methods:

Owing to the nation's lockdown situation, an online questionnaire-based survey was conducted through WhatsApp, Facebook, and E-mail among anesthetists working at different health-care sectors in India. The KAP with regard to the use of PPE during the COVID-19 and its psychological impact were assessed by using a prevalidated questionnaire. All analyses were performed using SPSS version 25.

Results:

Among 301 study participants, 189 (62.8%) had good knowledge and 90% had favorable attitudes. Despite 66.4% of the study participants having received formal training regarding the use of PPE during the COVID-19 pandemic, good practices were seen only in 44.4%. Irrespective of the demographic variable assessed, 90% of the anesthesiologists felt that working was more stressful in the operating room during this pandemic, due to challenges with respect to effective communication, restrictions in movement and visibility attributed to PPE as well as an alteration in the usual routine.

Conclusions:

Despite adequate knowledge and attitudes regarding the use of appropriate PPE, the translation into practice was deficient. Emphasis on the checklist, protocol-based approaches, and regular updates on practice recommendations will help to improve adherence to quality practices. Donning of appropriate PPE contributes to significant physical and emotional stress among anesthesiologists during the COVID-19 pandemic. A platform to provide psychological support is the need of the hour.
Rough-Fuzzy Support Vector Clustering with OWA Operators
Authors: Saltos Atiencia Ramiro , Weber Richard
Published: March 2022

Rough-Fuzzy Support Vector Clustering (RFSVC) is a novel soft computing derivative of the classical Support Vector Clustering (SVC) algorithm, which has been used already in many real-world applications. RFSVC’s strengths are its ability to handle arbitrary cluster shapes, identify the number of clusters, and e?ectively detect outliers by the means of membership degrees. However, its current version uses only the closest support vector of each cluster to calculate outliers’ membership degrees, neglecting important information that remaining support vectors can contribute. We present a novel approach based on the ordered weighted average (OWA) operator that aggregates information from all cluster representatives when computing ?nal membership degrees and at the same time allows a better interpretation of the cluster structures found. Particularly, we propose the induced OWA using weights determined by the employed kernel function. The computational experiments show that our approach outperforms the current version of RFSVC as well as alternative techniques ?xing the weights of the OWA operator while maintaining the level of interpretability of membership degrees for detecting outliers.

Authors: Oh Jin-Kyoung , Han Minji , Kim Byungmi , Park Eun Young
Published: March 2022

Purpose This study aimed to estimate the risk of cancer incidence and mortality according to adherence to lifestyle-related cancer prevention guidelines.Materials and Methods Men and women who participated in the general health screening program in 2002 and 2003 provided by the National Health Insurance Service were included (n=8,325,492). Self-reported smoking, alcohol consumption, and physical activity habits and directly measured body mass index were collected. The participants were followed up until the date of cancer onset or death or 31 December 2018. The Cox proportional hazard model was used to evaluate the hazard ratio (HR) for cancer incidence and mortality according to different combinations of lifestyle behaviors.Results Only 6% of men and 15% of women engaged in healthy behavior at baseline, such as not smoking, not drinking alcohol, being moderately or highly physically active, and within a normal body mass index range. Compared to the best combination of healthy lifestyle behaviors, the weak and moderate associations with increased all cancer incidence (HR < 1.7) and mortality (HR < 2.5) were observed in those with heavy alcohol consumption and in former or current smokers. HRs of cancer mortality were significantly increased among current smokers in most combinations.Conclusion Compared to full adherence to cancer prevention recommendations, unhealthy behaviors increase cancer risk. As few people meet these recommendations, there is a great opportunity for cancer prevention.

With the beginning of this year, the journal you have in your hand or read on internet, Geologia Croatica has (partly) changed Chief Editors. The former editors Prof. Igor Vlahović and Dr. Ivo Velić resigned with January 2008, because the inflow of manuscripts declined in recent years due to the fact that articles published in our journal were not considered for scientific promotion in Croatia. They wanted, and have succeeded, in remotivating the Croatian geological and larger scientific community, and since January 2008, articles published in Geologia Croatica will be eligible for scientific promotion. In this way they have helped to maintain the journal. Dr. Ivo Velić agreed to be reappointed as editor in the transitional period to stress the continuity of editorial policy and to help the new incoming editor, prof. Mladen Juračić, and the new editorial board.

Published: March 2022

At the western seaward coast of the island of Dugi Otok, unusual goethite mineralization occurs as the infilling of a system of thin crevices in the Upper Cretaceous limestones of the Adriatic carbonate platform. Goethite is exceptionally well ordered and shows a variety of chemical compositions ranging from almost pure FeO·OH to Al-substituted composition accompanied by high Si and P impurity. The most characteristic textural type assemblages are goethite and coarse grained calcite in composite aggregates. These aggregates contain Al-substituted goethite with metamorphic silicate minerals embedded in the core, (black goethite) armoured by the XRD-pure, almost stoichiometric goethite (brown goethite). The geochemical and mineralogical features of the mineralization suggest an ascending solution from a hidden metamorphic source. We speculate that the source could have been activated by the thermal influx linked to the Pliocene intraplate magmatism in the eastern segment of Adria.

The renewed deposition in the Palaeogene and the oldest part of the non-interrupted Palaeocene succession is characterized by the presence of Decastronema barattoloi (DE CASTRO), cyanobacterial tubes originally described in the Apennines. The reinterpretation of limestones from several sections located in the Kras region (NW part of the AdCP: Basovizza, Dolenja vas, Sopada, ?ebulovica) confi rmed the presence of these microfossils in peritidal sediments of Danian age (SBZ 1). The Cuisian (Late Lower Eocene) sediments, from eastern Istria (Brnjci section), Cres Island (Koroma?na Cove section) and Ravni kotari (Benkovac–Korlat section) contain individuals of this species in great numbers. The cyanobacterial tubes are scattered in laminated, fi ne grained mudstones and wackestones, immediately above the Cretaceous sediments (occasionally above bauxites or breccias). The Decastronema-bearing sediments pass upward into the Foraminiferal limestones of Cuisian age (SBZ 11, based on conical agglutinated foraminifera and alveolinids), allowing the age determination of the cyanobacterial remnants. The Palaeocene specimens are minute (up to about 180 ?m long), thick walled tubes that occur with the index fossil Bangiana hanseni DROBNE. The Eocene forms accompanied by ostracods, pelecypods, and miliolid and rotaliid foraminifera are segmented tubes, up to 400 mm long and usually thin walled.
Based on morphology and molecular data, Palisada rigida comb. nov. and Laurencia decussata comb. et stat. nov. (Rhodophyta, Rhodomelaceae) are proposed
Authors: Metti Yola
Published: March 2022

Inspecting herbaria collections of Laurencia rigida highlighted frequent misidentifications between L. rigida and L.heteroclada f. decussata, two poorly studied taxa from Australia. Recent collections of DNA material, including from topotypematerial, allowed for re-examination of these two taxa using molecular techniques. Detailed morphological andmolecular analyses based on two markers (rbcL and COI-5P) strongly supported these two taxa as being distinct fromeach other and requiring nomenclatural changes. Comprehensive morphological analyses highlighted features useful foraccurate identifications. Interestingly, L. rigida was found to belong to the genus Palisada with evidence from both themorphology and molecular data. Therefore, this study proposed recognizing L. rigida as Palisada rigida comb. nov. Moleculardata for L. heteroclada f. decussata on the other hand supported its separation from L. heteroclada, with too greata molecular distance to be considered a variety. Morphological characters that best separated P. rigida from L. decussataincluded seven characters; number of pericentral cells per vegetative axial segment, the presence of secondary pit connections,the presence of lenticular thickenings, tetrasporangia alignment, the presence of corps en cerise, holdfast morphology,and overall plant shape. Morphologically, L. heteroclada f. decussata was also separated from L. heteroclada,particularly by the following characteristics; ultimate branchlets morphologies, lower order branch lengths, primary axisand holdfast morphologies. Therefore, it was proposed that L. heteroclada f. decussata is recognized at a species level asL. decussata comb. et stat. nov.

Published: March 2022

Water temperature affects plankton survival and growth. The dinoflagellate Shimiella gracilenta survives using theplastids of ingested prey, indicating kleptoplastidy. However, studies on the effects of water temperature on kleptoplastidicdinoflagellates are lacking. We explored the growth and ingestion rates of S. gracilenta as a function of water temperature.Furthermore, using data on its spatiotemporal distribution in Korean coastal waters during 2015–2018, we predictedits distribution under elevated temperature conditions of +2, +4, and +6°C. Growth rates of S. gracilenta with andwithout Teleaulax amphioxeia prey as well as ingestion rates were significantly affected by water temperature. Growthrates of S. gracilenta with and without prey were positive or zero at 5–25°C but were negative at ≥30°C. The maximumgrowth rate of S. gracilenta with T. amphioxeia was 0.85 d-1, achieved at 25°C, and 0.21 d-1 at 20°C without prey. The ingestionrate of S. gracilenta on T. amphioxeia at 25°C (0.05 ng C predator-1 d-1) was greater than that at 20°C (0.04 ng Cpredator-1 d-1). Thus, feeding may shift the optimal temperature for the maximum growth rate of S. gracilenta from 20 to25°C. In spring and winter, the distributions of S. gracilenta under elevated temperature conditions were predicted notto differ from those during 2015–2018. However, S. gracilenta was predicted not to survive at some additional stationsunder elevated temperature conditions of +2, +4, and +6°C in summer or under elevated temperature conditions of +6°Cin autumn. Therefore, global warming may affect the distribution of S. gracilenta.

Intisari— Pencurian data pribadi merupakan tindakan kriminal dan melanggar hukum pada bidang teknologi informasi. Oleh karena itu, pengamanan data pribadi harus memiliki tingkat pengamanan yang lebih. Pengaman data pribadi dapat dilakukan dengan salah satunya memberikan password terhadap file data. Untuk menghindari pembobolan password dapat melakukan enkripsi terhadap password. Penelitian ini menggunakan algoritma Caesar Chiper dalam melakukan proses enkripsi. Namun beberapa algoritma kriptografi klasik yang telah banyak diketahui secara luas memiliki kelemahan yang dapat dipecahkan oleh criptanalysis. Oleh karena itu, untuk menghindari hal tersebut, sebelum melakukan enkripsi, algoritma caesar cipher dimodifikasikan terlebih dahulu kemudian dikonversikan kedalam code ASCII. Hasil modifikasi algoritma memberikan tingkat kompleksitas keamanan pesan, bila dibandingkan dengan caesar algoritma tanpa modifikasi. Hal ini ditunjukan dari hasil ciphertext yang menghasil ciphertext yang berupa karakter gabungan, membuat ciphertext semakin sulit untuk dibaca dan dipahami oleh manusia, sehingga dapat meningkatkan keamanan pesan dan dapat meminimalisir terjadinya peretasan oleh pihak yang tidak bertanggungjawab.

Internet of Things (IoT) Enabled Air Quality Monitoring System for Conventional and UAV Application
Authors: Kumar V. Vinoth , Sasikala G.
Published: March 2022

The purpose of this research is to make a system to read the air quality by detecting the various gases existing in the air by using Arduino UNO and node MCU module for conventional as well as UAV applications. The emergence of the Internet of Things (IoT) has made it easier to read the various gases present in the environment using smartphones from the workplace. The use of an Arduino processor with a Node MCU to construct an air quality monitoring system is discussed in this paper. The Node MCU is used to transmit live data for CO, CO2, and PM2.5 concentrations that are sensed by sensors. This data can be monitored continuously by the user via the mobile phone. The calibration of sensors is highly important while reviewing and grasping the large literature on the subject of IoT-based air quality monitoring. The proposed low-cost live air quality monitoring system uses commercially available gas sensors to detect environmental gases such as CO, CO2 and PM2.5 to monitor air quality in an outdoor area. The proposed system is used to correctly evaluate the experimental outcomes. This proposed prototype model incorporates an open-source cloud facility with Arduino for air quality monitoring, confirming low cost, comfort, and convenience for a customizable air quality monitoring system. As a result, the suggested system can simply be converted to use in a UAV for monitoring air quality in the outdoors at various altitudes, and it can be scaled up in the future.

Um mögliche Veränderungen des Gesprächsverhaltens (Lehrperson, Lernende) im Laufe dieser Fortbildung (1 Jahr) zu erfassen, werden unterschiedliche Analysemethoden verwendet, die unterschiedliche Perspektiven repräsentieren (allgemein- und fachdidaktische), unterschiedliche Aspekte der Gespräche fokussieren und quantifizierende mit qualitativen Verfahren kombinieren. Das Potenzial dieses Vorgehens wird anhand von zwei Beispielen – Videodaten einer Geschichts- und einer Mathematiklehrperson – illustriert und diskutiert, in denen je unterschiedliche Analyseverfahren zur Anwendung kommen.

Published: March 2022

Abstract:
Background: Chronic empyema thoracis (CET) is common in developing and developed countries despite advancement in diagnostic and therapeutic technologies. Some of the cases of CET can be managed with antibiotics and tube drainage alone, some of them managed with less extensive surgical procedure like video-assisted thoracoscopic surgery (VATS) or open decortication alone, while some of the complicated cases need extensive decortication and debridement of necrotic lung tissue or lobectomy. Our aim is to present our experience of management of cases of chronic empyema thoracis in children.
Methods and Material: This is a retrospective observational study of cases, managed at tertiary care center with chronic empyema thoracis. Records of cases of CET admitted, referred or transferred to department of pediatric surgery at our center over last three years were studied. Demographic data, clinical, radiological profile, surgical/ non-surgical intervention, hospital stay, aetiology, outcome was analysed. Follow up was up to the last recorded outpatient visit. This study is a retrospective observational study with small number of cases statistical tool are not used to draw any statistical interference.
Results: Twenty-nine cases with median age 3 years, male to female ratio was 25:4 were admitted over three years. Pre-operative bronchopleural fistula was seen in four. Five cases were managed conservatively, twenty underwent decortication alone while four cases required decortication along with lobectomy.  Tuberculosis was detected in three cases. A pyogenic organism was identified in ten cases only. Post-operative ventilation was required in three patients. There was no mortality. All thrived well at 12-18 months follow up.
Conclusions: Management of chronic empyema should be case based. Cases of CET in children can managed with conservative (with appropriate drainage of cavity, proper antibiotics, and nutritional build-up of child), thoracotomy and decortications alone or some time removal of disease lung also required depending on clinical and radiological finding of cases.

Ser propietario de inmuebles en México, a partir de la Reforma Constitucional y la promulgación de la Ley de Extinción de Dominio, puede tener consecuencias de pérdida del patrimonio, esta reforma es una consecuencia de la inseguridad por actividades de delincuencia organizada; por ejemplo en la celebración de contrato de arrrendamiento se otorga el uso y disfrute del inmueble, el inquilino demuestra ser una persona responsable pero realiza alguna actividad ilícita de acuerdo a la norma jurídica, el propietario confiado sufre la pérdida de su inmueble; entonces el Estado sin compensación alguna procede a extingir los derechos de propiedad. Esta investigación nos arroja una clara violación de derechos humanos. Utilizamos el método científico y descriptivo donde se concluye con el análisis de las reformas constitucionales.

This study aims to analyze students' interests in towards courses at English Department of Universitas Prima Indonesia in Medan. This qualitative study uses a case study design involving 60 students in the 5th semester of the Academic Year 2018 as participants. Data are obtained through questionnaires and interviews, thus the results showed that students have higher interests in the courses of teaching and education than other variety of courses taught in the English Department. The second interest was found in language skill courses. The reasons were to determine their future goals as teachers as well as the major program decision. Students argued that the majors they chose were following their interests, but some students were still unsure about the majors and interests they had chosen. This study suggests that lecturers should motivate the students to strengthen their competences particularly to identify the students’ interests in teaching or any other goals.

Los cambios ambientales provocados por la intervención humana conllevan a amenazas de desastres naturales, desequilibrio en los ecosistemas y pérdidas lamentables. El propósito del presente estudio consistió en brindar una descripción de cómo las instituciones educativas de la comuna uno de la ciudad de Medellín, preparan sus comités escolares para la atención y el manejo de desastres en relación con los procesos y las recomendaciones del Sistema Nacional de Gestión del Riesgo de Desastres de Colombia. Para el análisis se tuvo como referencia la información del plan de emergencias de la comuna uno, el cual fue realizado por el Departamento Administrativo de Gestión del Riesgo de Desastres. En los resultados se identificó que no todas las instituciones educativas de la comuna tienen conformados los comités escolares para la atención de desastres, no obstante, se hacen responsables de la gestión del riesgo, la identificación de las amenazas, la realización de simulacros, la capacitación en primeros auxilios, la bomberotecnia, la evacuación y las mejo[1]ras locativas. En conclusión, las instituciones educativas de la comuna uno de la ciudad de Medellín, se están preparando para responder de la mejor manera ante la materialización de un fenómeno amenazante.

Emociones, una conversación entre Filosofía, Neurociencia y Estética
Authors: Agudelo Monsalve Carolina
Published: March 2022

El objetivo principal de este articulo es acercarse a la comprensión teórica sobre las emociones desde dos perspectivas, una filosófica y otra neurocientifica. A la vez, generar un dialogo con teóricos de la estética y la memoria con el fin de configurar una propuesta para reestetizar las emociones desde el recuerdo o la memoria alegre como herramienta para encontrar sentido a la vida y potenciar la acción de los sujetos. Esta potencia se ha visto disminuida entre muchas otras razones por la naturalización de afectos negativos como la tristeza y el miedo o la falta de consciencia frente a lo que significan las emociones en la construcción de realidades.
