Yttrium aluminum garnet (YAG) ceramics doped with Ce3+ was prepared by dry compaction using the common uniaxial pressing under powerful ultrasound assistance (PUA). The structure and luminescent properties of sintered ceramics were investigated. It was demonstrated that the powerful ultrasonic assistant during the dry pressing has a positive effect on the structural and luminescent characteristics of YAG: Ce3+ ceramics. The sintered material consolidation is very intensive accompanied by a decrease in the number of pores and grain growth at a sintering temperature of 1650 ºC. The luminous efficiency of YAG:Ce3+ ceramics vary from 120 to 219 lm/W (without ultrasound treatment) and from 120 to 250 lm/W (prepared with ultrasound conditions) closely related with the phase purity and implicitly with sintering temperature. It was demonstrated the positive effect of PUA on the thermal properties of ceramics.

Optical properties of lanthanum-gallium silicate (La3Ga5SiO14), lanthanum-gallium tantalate (La3Ga5.5Ta0.5O14), calcium-tantalum-gallium silicate (Ca3TaGa3Si2O14) crystals in the near ultraviolet (UV) and visible wavelength ranges (200-800 nm) have been studied. For the first time the angles of deviation of the moments of the dipole transition spectral dependences theta(λ) were used to characterize the absorption processes in these crystals. These dependences make it possible to reveal absorption bands that are weakly noticeable on the transmission coefficients spectral dependences, and to estimate the degree of deviation of the dispersion dependence theta(λ) from the value theta=45o corresponding to an ideal ordered crystal. Analysis of theta(λ) dependencies showed that in the studied wavelength range, the lowest deviation from theta =45o is observed in Ca3TaGa3Si2O14, and the highest - in La3Ga5SiO14. The coefficients of the specific rotation angle of the polarization plane rho were obtained by the spectrophotometric interference method in polarized light. The measured values are best approximated by the Vyshin equation. For the first time, dependences of the modified Drude formula 1/rho=f(λ2) were calculated for these crystals. These dependences should be linear in case of an ideal crystal. The largest deviation from the linear dependence is observed for La3Ga5SiO14 crystals, and the lowest for Ca3TaGa3Si2O14. The discrete values of the refractive coefficients No and Ne were measured by the prism method. La3Ga5.5Ta0.5O14 crystals have the highest refractive coefficients, Ca3TaGa3Si2O14 crystals have the lowest. The obtained values are approximated by the Sellmeier equation.

Fluoride nanocrystals co-doped with lanthanide ions are well known due to the possibility of conversion near-infrared (NIR) radiation into photoluminescence with large anti-Stokes shift. Owing to upconversion effect, such nanomaterials have shown great potential in photonics and biomedicine. However, fluoride nanoparticles can be reconfigured to photoluminescence with a Stokes shift into the near-infrared region of the spectrum. In this work, we focused on the properties of NaRF4: Yb3+, Er3+, Ce3+ (R = Y, Lu) nanoparticles exhibiting intense stokes luminescence in the vicinity of 1530 nm at 975 nm excitation. Photoluminescence quantum efficiency of synthesized nanoparticles was evaluated as 28% at 0.6 W/cm2 excitation intensity. Based on the photoluminescent properties of nanoparticles we designed compact waveguide amplifier for C-band telecommunication and developed time gated imaging system for NIR-to-NIR biovisualization.

Single color centers in the LiF crystal were studied by confocal fluorescence microscopy with analysis and statistical processing of the time dependences of their fluorescence intensity. The possibility of identifying quantum systems whose selection by luminescence excitation (absorption) spectra, luminescence spectra, and luminescence decay time is difficult due to their overlap or due to the coincidence of the corresponding characteristics of different centers is shown. An additional identification feature in this case is the flicker frequency and other characteristics of the time dependences of the luminescence intensity. The efficiency of the method is demonstrated by the example of two color centers of different nature (F2 and F3, stabilized by an impurity–vacancy dipole) in a lithium fluoride crystal.

Published: June 2023

Microorganisms that are capable of degrading lignocellulolytic materials can produce extracellular cellulase complexes. Microorganisms are an excellent alternative for the production of cellulolytic complex, since these sources have a high power of multiplication. In this work, we researched the production by the fungus Moniliophthora perniciosa. The production and pH and temperature optimum optimization were studied by Response surface methodology and carboxymethylcellulase (CMCase) characterization. Thermal stability was evaluated at 60, 70, 80 and 90°C. Doehlert experimental design was employed using inductor concentration in five levels (3.0, 4.5, 6.0, 7.5 and 9.0 g L-1 of yeast extract) and fermentation time was studied in three levels (7, 14 and 21 days). The production of CMC enzyme was higher in the concentration of 7.0 g L-1 of yeast extract and 19 days fermentation time. CMCase showed optimum pH and temperature at 7.2 and 47°C, respectively. The CMCase retained 88.66% of residual activity after 30 minutes of incubation at 90°C. Due to the characteristic of thermal stability, this enzyme will be studied to be expressed in recombinant microorganisms.

Published: June 2023

Background

Research clearly demonstrates social determinants of health (SDOH) impact health outcomes. Provider consideration of patient SDOH in prevention and treatment planning is critical for improved health care quality and health equity. Despite awareness of the connections between SDOH and improved population health, research demonstrates few providers document patient SDOH.

Objective

This qualitative study aimed to better understand the barriers and facilitators of SDOH assessment, documentation, and referral in different health care settings and roles.

Methods

Individual semistructured interviews were conducted with practicing health care providers in South Carolina between August 25, 2022, and September 2, 2022. Participants were recruited via community partners’ web-based newsletters or listservs using a purposive sampling design. An interview guide with 19 questions was used to explore the following research question: How do SDOH impact patient health and what are the facilitators and barriers experienced by multidisciplinary health care providers assessing and documenting patient SDOH?

Results

Participants (N=5) included a neonatal intensive care unit registered nurse, a nurse practitioner, a certified nurse midwife, a family and preventive medicine physician, and a counselor (licensed clinical social worker) with careers spanning 12 to 32 years. Participant responses are presented according to the following 5 themes: participants’ understanding of SDOH for the patient population, assessment and documentation practices, referrals to other providers and community-based resources, barriers and facilitators of SDOH assessment and documentation, and SDOH assessment and documentation training preferences. Overall, participants were aware of the importance of including patient SDOH in assessment and intervention but noted a variety of institutional and interpersonal barriers to assessment and documentation, including time constraints, perceptions of stigma around discussion of SDOH, and limited referral protocols.

Conclusions

Incentivizing inclusion of patient SDOH in health care must be facilitated from the top down, so assessment and documentation can be universally implemented in a pragmatic way that works for providers in a variety of roles and settings for the betterment of health care quality, health equity, and improved population health outcomes. Partnering with community organizations can serve to augment health care organizations’ resource and referral availability for addressing patients’ social needs.

Published: June 2023

UNSTRUCTURED

Acne Keloidalis Nuchae (AKN) is a chronic inflammatory condition which in vast majority of cases is treated medically. In rare cases where the condition is severe and refractory to treatment, surgical intervention is necessary. There is still no consensus on the best surgical method of treatment, but the wish for a short postoperative healing period and a cosmetically acceptable result is the same for all cases.
In this case we present a patient with severe refractory AKN, treated with excision and direct Split-Thickness Skin Grafting (STSG) in combination with Negative Pressure Wound Therapy (NPWT). This, with a both shorter healing period than previously described and with a satisfactory cosmetic result.

Authors: Beesoon Sanjay , Drobot Ashley , Smokeyday Melissa , Ali Al-Bakir , Collins Zoe , Reynolds Colin , Berzins Sandra , Gibson Alison , Nelson Gregg
Published: June 2023

BACKGROUND

Of all the care provided in health care systems, major surgical interventions are the costliest and can carry significant risks. Enhanced Recovery After Surgery (ERAS) is a bundle of interventions that help improve patient outcomes and experience along their surgical journey. However, given that patients can be overwhelmed by the multiple tasks that they are expected to follow, a digital application, the ERAS app, was developed to help improve the implementation of ERAS.

OBJECTIVE

The objective of this work was to conduct a thorough assessment of patient and provider experiences using the ERAS app.

METHODS

Patients undergoing colorectal or gynecological oncology surgery at 2 different hospitals in the province of Alberta, Canada, were invited to use the ERAS app and report on their experiences using it. Likewise, care providers were recruited to participate in this study to provide feedback on the performance of this app. Data were collected by an online survey and using qualitative interviews with participants. NVivo was used to analyze qualitative interview data, while quantitative data were analyzed using Excel and SPSS.

RESULTS

Overall, patients found the app to be helpful in preparation for and recovery after surgery. Patients reported having access to reliable unbiased information regarding their surgery, and the app provided them with clarity of actions needed along their surgical journey and enhanced the self-management of their care. Clinicians found that the ERAS app was easy to navigate, was simple for older adults, and has the potential to decrease unnecessary visits and phone calls to care providers. Overall, this proof-of-concept study on the use of a digital health app to accompany patients during their health care journey has shown positive results.

CONCLUSIONS

This is an important finding considering the massive investment and interest in promoting digital health in health care systems around the world.

Published: June 2023

BACKGROUND

Interest in the application of predictive risk models (PRMs) in health care to identify people most likely to experience disease and treatment-related complications is increasing. In cancer care, these techniques are focused primarily on the prediction of survival or life-threatening toxicities (eg, febrile neutropenia). Fewer studies focus on the use of PRMs for symptoms or supportive care needs. The application of PRMs to chemotherapy-related symptoms (CRS) would enable earlier identification and initiation of prompt, personalized, and tailored interventions. While some PRMs exist for CRS, few were translated into clinical practice, and human factors associated with their use were not reported.

OBJECTIVE

We aim to explore patients’ and clinicians’ perspectives of the utility and real-world application of PRMs to improve the management of CRS.

METHODS

Focus groups (N=10) and interviews (N=5) were conducted with patients (N=28) and clinicians (N=26) across 5 European countries. Interactions were audio-recorded, transcribed verbatim, and analyzed thematically.

RESULTS

Both clinicians and patients recognized the value of having individualized risk predictions for CRS and appreciated how this type of information would facilitate the provision of tailored preventative treatments or supportive care interactions. However, cautious and skeptical attitudes toward the use of PRMs in clinical care were noted by both groups, particularly in relationship to the uncertainty regarding how the information would be generated. Visualization and presentation of PRM information in a usable and useful format for both patients and clinicians was identified as a challenge to their successful implementation in clinical care.

CONCLUSIONS

Findings from this study provide information on clinicians’ and patients’ perspectives on the clinical use of PRMs for the management of CRS. These international perspectives are important because they provide insight into the risks and benefits of using PRMs to evaluate CRS. In addition, they highlight the need to find ways to more effectively present and use this information in clinical practice. Further research that explores the best ways to incorporate this type of information while maintaining the human side of care is warranted.

Development of a cyberchondria severity scale for university students during the COVID-19 pandemic (Preprint)
Authors: Hsu Wan-Chen
Published: June 2023

BACKGROUND

Owing to the rapid development of the Internet, individuals can easily obtain health information online, which may positively or negatively affect their thoughts and behaviors. The coronavirus disease (COVID-19) pandemic caused millions of deaths worldwide. People’s daily lives were disrupted when restrictions were imposed preventing them from going outside, resulting in reduced physical activity. This phenomenon was exacerbated during the COVID-19 pandemic.

OBJECTIVE

Cyberchondria is a hybrid word that signifies a state in which individuals compulsively search for health-related information online because of health distress or anxiety, resulting in symptoms of such conditions. The objective of this study was to develop a university student cyberchondrial severity scale and understand the current situation.

METHODS

Exploratory factor analysis was conducted using 145 valid questionnaires. Subsequently, a nationwide survey was conducted in various universities in Taiwan; 802 questionnaires were used for confirmatory factor analysis, and the current status of cyberchondria among university students was analyzed.

RESULTS

The factor analysis led to a cyberchondria severity scale for college students with four constructs: increased anxiety (α=.908), obsessive-compulsive hypochondria (α=.865), perceived controllability (α=.884), and online physician-patient interaction (α=.858), and a total scale Cronbach's alpha 0.924, variance of 66.81%. The confirmatory factor analysis showed that item reliability ranged from 0.50 to 0.86, factor loadings ranged from 0.71 to 0.93, and the composite reliability for latent variables ranged from 0.83 to 0.90 (p<.001). The extracted average variance lay from 0.46 and 0.60. There were significant differences in the various dimensions of the university student cyberchondria severity scale, of which perceived controllability had the highest score and obsessive-compulsive hypochondria had the lowest score (F3,2403=256.26, p<.001).

CONCLUSIONS

This study is the first to develop a cyberchondria severity scale tailored to university students. The instrument was found to be reliable and valid. The various constructs were significantly correlated with each other, and increased anxiety and obsessive-compulsive hypochondria showed a significant moderate positive correlation with perceived controllability and online physician-patient interaction. These findings provide researchers, policymakers, and practitioners with evidence and opportunities to focus on preventive actions. The study can also be used as a reference for a broad-based qualitative and quantitative study design for future research to obtain a deeper understanding of online information searches and cyberchondria. Since studies on cyberchondrial severity scales are in their infancy, further research should examine the factors affecting cyberchondria, promoting online health information searches, and reading comprehension behavior as possible techniques for development.
Anonymous, Chat-based Peer Support Reduces Loneliness in Older Adults (Preprint)
Authors: Kilby Kimberly , Zhang Hao , Nagra Harpreet
Published: June 2023

BACKGROUND

Older adults have a high rate of loneliness which contributes to increased medical morbidity and mortality. Peer support interventions combine persons with a similar struggle or condition to create an environment of mutual support and have demonstrated positive benefits across a broad range of medical conditions and demographics.

OBJECTIVE

This case study describes the experience of a cohort of over 700 adults aged 65 years and older who engaged at least once in anonymous, chat-based, digital peer support to determine if participation led to measurable change in certain emotions.

METHODS

Chat narratives from peer conversations were analyzed to produce a quantitative measure of change in emotion (loneliness, stress, sadness, anger, and optimism) using a third-party public sentiment analysis natural language processing model. Sentiment analysis evaluated each user’s chat messages in temporal order and then normalized across various interaction lengths and reconstructed to produce a collective trend for each emotion.

RESULTS

As the chat progressed, there was a collective decrease in all variables, including loneliness, anger, sadness, and stress with a corresponding increase in optimism.

CONCLUSIONS

Chat-based peer support may be a viable intervention to help address loneliness in older adults and presents an alternative to traditional care. This form of peer support may also be an option to address anger, sadness, and stress. These are promising, hypothesis-generating results that, given the simplicity and scale of the intervention, support the need for further study in this area to expand the evidence for such cost-effective options available to address loneliness among populations of elderly adults.

Health myths are one of the factors that can hinder the achievement of government programs in the health sector, resistance that arises from the community can be even greater if the myths that are believed to have taken root in social life and are considered to have magical elements in their implementation. To change the wrong health beliefs in society, the role of health workers in providing health education and health literacy to all levels in society is important. Based on the problems found, the team's goal was to improve nursing students’ knowledge about health myths in Indonesia. The implementation of these activities was carried out for 199 nursing students from 7 provinces (DKI Jakarta, West Java, Banten, Jambi, East Java, Central Java, and Southeast Sulawesi) online through Zoom. This activity is the final series of a series of activities carried out by the Institute of Training, Education, and Research, Nurse Share Idea (NSID) about health myths that exist in Indonesia, while the implementation of this series of activities has been carried out from November 2020 to August 2021. The results of the Wilcoxon test of activities carried out can be seen in table 3. which shows that the value of sig = 0.002 (<0.005) means that the activities carried out have a positive impact on improving nursing students’ knowledge about health myths in Indonesia. Nurses have a role in facilitating public access to reliable health knowledge and information related to existing mythical issues. In supporting the role of nurses, activities to increase the knowledge of nurses and nursing students on topics related to health myths are also an important part to be considered and carried out on an ongoing basis because it has been proven to have a positive effect on its implementation.

Pondok Pesantren, as one of the major boarding-based education systems in Indonesia, faces significant challenges in preventing and controlling infectious disease transmission. Huge number of students (santri), crowded dormitories, shared lavatories, limited healthcare facilities, and intense social interactions increase the risk of transmitting infectious diseases within the facilities. This study aims to provide initial assessment of the history of infectious diseases and the spread of infectious diseases among santri living in Pondok Pesantren before conducting training and intervention related to infectious diseases prevention and control programs. It is a quantitative study using a descriptive analysis approach conducted in July-September 2022 at Pondok Pesantren Assalafiyah 2 Mlangi. A non-probability sampling with total sampling of 848 santri was used. The data were collected using self-administered questionnaires developed on Google Form and imported to Microsoft Excel for further data analysis. The results indicate that the majority of the santri have a history of infectious diseases (90.7%) during their time living in Pondok Pesantren. The most common infectious diseases found were influenza (55.40%), scabies (20.94%), conjunctivitis (6.50%), varicella (6.11%), herpes simplex (2.21%), tuberculosis (1.39%), and measles (1.13%). During the COVID-19 pandemic, a total of 21.11% of the students had been exposed to COVID-19 and 98.47% of the students had received vaccinations. Considering these findings, it is essential for the staff and students living in Pondok Pesantren to understand the steps to prevent the occurrence of infectious diseases and be able to identify and provide initial treatment to stop the transmission of the disease. The development of digital health intervention using a website or application will be implemented to help the students report and consult case findings to medical experts.

Published: June 2023

Indonesia has implemented the National Health Insurance (Jaminan Kesehatan Nasional/JKN) program administered by the BPJS Kesehatan (Health Care and Social Security Agency) to improve the quality of community health and well-being. In eight years, JKN implementation has had many challenges; complicated registration, premium, unsatisfactory service, and the lack of community participation. Policies regarding JKN should be known and understood. This study aimed to know the knowledge, attitudes, and behaviour towards health insurance that will be useful for stakeholders to develop public policies. This study was conducted in Umbulsari B sub-village in Sumberharjo, Prambanan, Yogyakarta, the lowest area of JKN participation based on Sleman HDSS data. We used a cross-sectional design study among 91 respondents who filled out a paper sheet questionnaire that consisted of five sections; demographic characteristics and insurance participation, knowledge, attitudes, actions, and satisfaction with the JKN program. Then, the community service activities; coordination with local stakeholders; JKN participation identification using CHIKA; educational media production and publication. Local stakeholders said that awareness about JKN is low. CHIKA data identification from 529 ID shows that 78.1% had become JKN participants, and 73.3% were "active". The respondents answered most of each knowledge point correctly (score >90%). But there are several things that respondents disagree with: "every participant will get the same health services (19.78%) in attitude point, and health workers in health facilities do not discriminate (21.21%) in satisfaction point. Then 21.21% of respondents rarely use health services routinely for medical check-ups. We developed educational media about the importance of JKN, as well as using CHIKA and Pandawa tutorials. Education about health insurance needs to be carried out continuously according to the local cultural context and innovations so that the community remains protected from the financial burden of accessing health services.

Introduction: This study intends to assess the impact of COVID-19 information-related sources, as well as one's knowledge, attitude, and behavior concerning vaccine acceptance, vaccine hesitancy, and vaccine refusal in a single vaccination site in Jambi, IndonesiaMethods: We conducted a cross-sectional study with total sampling in Puskesmas Putri Ayu, Jambi. The inclusion criteria are adults (>18 years) vaccinated with CoronaVac. Our exclusion criteria were refusal to participate in the study for any reason, contraindicated to COVID-19 vaccine administration, and receiving the second vaccine jab.Results: We include 245 respondents with a slight female predominance (53.5%). The majority is in the age group of 26-35 years old (20.8%). In the multivariate analysis, having a family member with≥2 comorbidities is almost six times more likely (OR 5.99, 95%CI 1.84-19.54; p-value = 0.003) to put a respondent in the vaccine hesitance and refusal group. Respondents who trust in friends or family are 2.25 times more likely (95%CI 1-5.04; p-value = 0.048) to belong in the vaccine hesitance and refusal group. Respondents who trust the internet are 0.45 times more likely to belong in the vaccine hesitance and refusal group (95%CI 0.21-0.96; p-value = 0.04). Lastly, respondents with poor knowledge are 0.58 times more likely (95%CI 0.38-0.88; p-value = 0.011) to belong in the vaccine hesitance and refusal group.Conclusions: This finding will be relevant to increasing vaccination uptake by targetting family members with comorbidities and devising a strategy to make their peers trust the COVID-19 vaccine to increase the uptake.

Published: June 2023

Garbage is a problem in urban areas. One of the efforts that can be made against the waste problem is reprocessing it into useful materials. PKK is a family welfare coaching group that can turn waste into media material for educational games for PAUD students through self-help groups. The goal of this community service and research is to empower and assist PKK activist groups in optimizing waste as an educational game tool for children from a young age. The method used is a quantitative and qualitative approach. The quantitative data are in the form of demographic data, knowledge, and skills. In contrast, the qualitative data comes from structured interviews and FGDs with a grid of questions about waste, the efforts that have been made, and the benefits of recycling the waste as an educational game tool. The measuring tool used is a questionnaire about waste knowledge and a waste processing checklist sheet. The target of this activity was 25 PKK groups at RW 02 of Merjosari Subdistrict, Lowokwaru District, Malang City, and it was carried out in June-August 2019. This Gempa Perekat activity consisted of health education, focus group discussion, and forming self-help groups. The result of this activity is that the respondent's knowledge increases after receiving health education about waste management (0.000). There is an average skill in processing waste into a good educational game tool (73) among respondents, and they stated that all this time, waste has been disposed of, put in plastic bags, and burned. Furthermore, respondents hoped that there would be waste management that could be useful for PAUD students by processing waste into educational games. The conclusion of this activity is the Gempa Perekat program as a form of intervention in dealing with waste in the city by empowering the PKK as a self-help group in making educational game tools for PAUD students from waste.

This descriptive study was conducted with multisector stakeholders as the study population in Lombok Barat District, Indonesia from August – Desember 2022. Data were collected through observations and documents. Data analysis was done descriptively. This study showed that stakeholders’ engagement is a continuous activity to raise their awareness concerning the stunting issues and encourage them to be actively involved in the programs. Needs assessment and internal planning development, lobbying and advocacy, raising leader commitment, development planning and strategies, and capacity building were accomplished in this study to engage related stakeholders in the stunting interventions in Lombok Barat. The stakeholders who should be involved in the programs are not limited to the stakeholders from the health sector, but must include inter-sectoral stakeholders due to the complexity of the stunting determinants. Moreover, it is necessary to develop key messages to increase the stakeholders’ engagement according to their own needs. Additionally, leadership, leaders’ awareness of health issues as well as their commitment were identified as the main social capital for community action in the stunting prevention and control efforts.

Authors: Liu Ke
Published: June 2023

To solve the problem that model may not be convergent owing to datasets with small sample sizes results from the secrecy of labs, a fire detection method for lab fire detection based on CNN (Convolutional Neural Network) and transfer leaning is proposed. Experiments of transfer learning were conducted with configuration of super parameters and a small lab fire dataset, whose pre-trained models are GoogLeNet, ResNet and MobileNet trained with ImageNet dataset. We analyze and assess the loss function curve and the performances of the above models. Result shows that MoblieNet model is chosen to be the optimum model for fire detection, providing a reference to lab fire detection with small sample size datasets. Different from artificial fire surveillance, the proposed method based on CNN and transfer learning realize real-time, autonomy and efficient fire detection.

Authors: Gashan Amani , Bamanger Ebrahim
Published: June 2023

In the foreign language context, little research has been undertaken to explore university students’ attitudes towards virtual learning for language instruction. The purpose of this study was to investigate EFL learners’ attitudes toward utilizing the Second Life virtual world as an online instructional and language learning tool. To achieve the study purposes, a descriptive research design was used with a questionnaire to gather data, after ensuring its validity and reliability. Forty-one undergraduates who were enrolled in two CALL classes at a school of education participated in the study. Overall, the results suggest that the majority of EFL undergraduates have favorable attitudes toward using virtual games and that the use of Second Life served well as an online instructional tool for language learning. Based on the results of the current study, EFL instructors may be encouraged to integrate virtual world games to augment their students’ learning by providing them paths to engage in authentic communication with the target language users. Further, the integration of virtual learning is a promising alternative in times of pandemics when social distancing is an obligation. Such ends require that instructors plan some virtual world-based tasks of a goal-driven nature. Further research directions include implementing qualitative tools to explore how learners react to the nature of virtual world games, specifically in relation to the users’ ability to claim different identities.
Representation of Socio-cultural Authenticity in Post-colonial Sri Lankan Poetry in English
Authors: Karunaratne K M Sunethra Kumari
Published: June 2023

The criticisms of Sri Lankan Literature in English have emphasized the inherent inability of Sri Lankans to produce competently written poetry in the English language when compared with the native English standards. These critics have underrated or completely have overlooked the significant achievements and a substantial amount of high-quality English poetry which carries authentic Sri Lankan flavor. Only a handful of researches on Sri Lankan Poetry has investigated the “genuine Sri Lankanness” of the subject. This study investigated how the authentic Sri Lankan flavor is represented in Sri Lankan poetry in English which were subjected to timely socio-cultural movements. The Sinhala-Buddhist identity, the criticism of Tamil separatism, the suffering undergone by the Sinhalese in Lankan civil war are elucidated combined with a typically Sri Lankan flavor. The absence of researches on this particular aspect where the poets have employed the Sri Lankan flavor in their writing tempted the researcher to study the area in detail. A qualitative approach with a content, thematic and discourse analyses have been applied in this research in elucidating the areas of Sri Lankan flavor in the literary texts. The true Sri Lankanness represented in the literary texts of selected Sri Lankan authors representing areas such as relationships, politics, social contexts, religions as well as education have been investigated and emphasized in this study.
Aportes en la discusión de un nuevo concepto de patrimonio gastronómico desde la complejidad y el diálogo de saberes
Authors: Borrega Reyes Yolanda
Published: June 2023

El patrimonio gastronómico se ha estudiado tradicionalmente desde enfoques socioculturales y/o nutricionales. Su comprensión, como un sistema vivo, dinámico y en constante cambio y transformación, precisa de una reflexión crítica en cuanto al concepto tradicional de Patrimonio Gastronómico siendo necesarias nuevas propuestas –en este caso, desde la complejidad y la transdisciplinariedad– que nos permitan profundizar en el conocimiento desde nuevos enfoques. En este trabajo se hace una crítica al concepto desde la perspectiva de la UNESCO y de autores académicos, para mostrar dos ejemplos de aportes locales a este concepto desde la visión quechua y aymara. Mediante el diálogo de saberes se propone un modelo para abordar los estudios referentes al patrimonio gastronómico y los procesos de patrimonialización, y puesta en valor.

Authors: Mastandrea Paula-Belén , Michel-Fariña Juan-Jorge , Cambra-Badii Irene
Published: June 2023

El contexto educativo actual requiere de docentes éticamente competentes para la detección y/o el abordaje de situaciones difíciles. Las series son una vía privilegiada para el acceso a situaciones éticamente controvertidas en tanto producen y reproducen imaginarios sociales actuales. Este artículo presenta la revisión y reelaboración de un esquema conceptual que reúne los grandes principios que organizan la ética en la educación a partir de la serie Merlí (2015-2018). Se realiza un análisis de contenido de los 40 episodios de la seriepara relevar las situaciones éticamente controvertidas allí presentes. Los resultados demuestran que estas controversias ocupan un lugar relevante en la serie y la necesidad de actualizar un esquema conceptual sobre los grandes principios que organizan la ética en la educación. Éste es un recurso clave para la elaboración de un dispositivo diagnóstico de sensibilidad ética y una herramienta de la formación docente en materia de ética profesional a partir de series contemporáneas.

Published: June 2023

Abstract: The rapid technical development of technology in the fields of sensors, data acquisition and communication, signal analysis and data processing has prepared SHM with great benefits. SHM often provides reliable data on the real conditions of a structure. Bridges, wind farms, nuclear power plants, geotechnical structures, historical buildings and monuments, dams, offshore platforms, pipelines, ocean structures, airplanes, turbine blades etc. may be objects for monitoring, just to mention some. The monitoring can be periodic or continuous, short-term or long term, local or global and the monitoring system can consist of a few sensors up to hundreds or even thousands of them depending on the demands of the monitoring object. As the area of the subject is numerous, this thesis principally brings up and discusses the subject from a civil engineering point of view. Cracking concrete, collapsing and deteriorating constructions are a not only phenomena that occurs in old structures.

Authors: A Azil Muhammed
Published: June 2023

Abstract: Scarcity of natural resources and insufficient agricultural food production due to increase in population is a major problem in today’s world.To overcome this problem, hydroponic system is used which is a type of indoor agriculture style that is independent of weather, and it also avoids the cost of plowing and labor works. The Hydroponic farming is the method of growing plants without making use of sunlight & soil. In this method, the plants are grown with their roots exposed to the mixture of minerals with water instead of underground soil with the help of NFT( Nutrient film technique) and DFT( Deep flow technique) . Many studies has been conducted in developing the food production techniques using hydroponics. An IOT technology is used in hydroponics system to preserve natural resources and increase food production by monitoring and controlling the micro-climate and environmental factors . Therefore we will be conducting a comparitive study on hydroponic plants first by controlling the parameters and then without controlling the parameters to represent the difference in productivity of crops in each case. By doing research on multiple papers related to hydroponics and different techniques used to controll and monitor various factors, we are able to understand and analyse the techniques which has been used in different research papers.
