Telemedicine is the utilization of electronic facts to correspond expertise for sustaining healthcare when physical distance part the users. Within the same time frame, patient-related data can be simultaneously get collected for large number of people using remote monitoring. However, there is always a disadvantage if any issue arises due to software and hardware. Thus, computer-based patient monitoring can be problematic at sometimes if we exclusively depend on computer system. There should always be a balance between computer dependency and human intelligence use. Each and every one’s life difference can be made by maintaining the balance between the two. Here, in this review article, we discussed the historical perspectives, telemedicine system concepts, telemedicine centers infrastructure, role in diverse spheres, types of telemedicine technology, applications in public health, current initiatives, and finally the success and popularity of telemedicine during COVID-19 pandemic.

Published: May 2022

Objective: Brown HT is an extensively used food color. Our objective was to evaluate the possible toxic effect of Brown HT on male reproductive functions in rats.
Methods: Brown HT was administered to male rats orally at 100, 200, and 400 mg/kg body weight/day for a period of 30 days. At the end of this period, different types of parameters related to male reproductive physiology and activities of different antioxidant enzymes were measured by spectrophotometric method using standard protocols. The serum hormonal levels were measured by Chemiluminescence Immuno Assay method using the kit.
Results: We have observed significant decrease in mean body weight, gonado somatic index, number of epididymal sperms, percentage of motile sperms, and also decrease in serum level of luteinizing hormone, follicle-stimulating hormone (FSH), and testosterone in a dose dependent manner in Brown HT exposed rats. The activities of antioxidant enzymes such as superoxide dismutase, catalase, glutathione reductase, glutathione peroxidase, and glutathione-S-transferase have been decreased and the level of malondialdehyde, a biomarker of lipid peroxidation has been increased significantly in exposed rats. Histopathology of testes also showed degeneration of germ cells in somniferous tubules in Brown HT exposed rats.
Conclusion: According to this result, it is concluded that Brown HT suppresses the male reproductive functions probably by producing oxidative stress in testicular tissues and suppressing the hypothalamus-anterior pituitary-testicular axis in rat.

Published: May 2022

Objectives: The objectives of the study were to study the efficacy, safety, and cost-effective analysis of low-dose etoricoxib and add-on paracetamol versus therapeutic dose etoricoxib in patients who experienced pain after tooth extraction.
Methods: Patients were recruited and randomized to two study groups E1P and E2 on etoricoxib 30 mg and add-on paracetamol 500 mg 8 hourly and etoricoxib 60 mg once respectively for 3 days. The efficacy was assessed by visual analog scale, pain relief score, and global evaluation score. Patients were assessed at 0, 6, 24, 48, and 72 h. Safety was assessed by adverse drug reactions reported by the patients after 72 h. Cost-effective analysis was done by calculating the cost of treatment and the cost-effective ratio in both groups.
Results: Eighty patients completed the study having 40 patients in each group. Mean pain intensity reduction, mean pain relief score, and global evaluation score all showed significantly better results (p<0.05) in Group E1P as compared to Group E2 at 6, 24, 48, and 72 h, respectively. No patient had reported any serious adverse drug reaction in both the groups; however, incidence of headache and fatigue was twice in the etoricoxib only treated group (n=4) than low-dose etoricoxib-treated group (n=2). The treatment cost of Group E1P was lesser than Group E2 and was also cost effective.
Conclusion: Low-dose etoricoxib with add-on paracetamol is a better analgesic than therapeutic dose etoricoxib and is also found to be safer and cost effective.

Objectives: Diabetic retinopathy (DR) is a major microvascular complication of diabetes. The purpose of the study is to correlate the risk factors such as duration of diabetes, hypertension, dyslipidemia, HbA1c, and high serum creatinine with severity of diabetic retinopathy.
Methods: This is a hospital-based cross-sectional study conducted on 50 patients of diabetic retinopathy from March 2021 to August 2021. Best corrected visual acuity, slit lamp examination, and detailed fundus examination were done and grade of diabetic retinopathy was noted. The severity of diabetic retinopathy is correlated with duration of diabetes, HbA1c, serum cholesterol, BP, Hb%, and serum creatinine levels.
Results: In our study, there was found to be a statistically significant association between duration of diabetes (p=0.03) and HbA1c levels (p=0.04) with severity of diabetic retinopathy whereas dyslipidemia (p=0.7), hypertension (p=0.8), high serum creatinine levels (p=0.4), and anemia (p=0.3) were shown to have no significant association with severity of diabetic retinopathy.
Conclusion: In our study, the risk factors such as duration of diabetes and poor glycemic control have statistically significant association with severity of diabetic retinopathy and hypertension, dyslipidemia, anemia, and high serum creatinine have no significant association with severity of diabetic retinopathy. Thus, good glycemic control and regular screening for DR changes are the key to prevent progression of DR and to improve the quality of vision in diabetic patients.

Published: May 2022

Abstract: Nowadays, people face various diseases due to environmental conditions and their living habits. So the prediction of disease at an earlier stage becomes an important task. But the accurate prediction based on symptoms becomes too difficult for the doctor. The correct prediction of disease is the most challenging task. To overcome this problem data mining plays an important role to predict the disease. Medical science has a large amount of data growth per year. Due to the increasing amount of data growth in the medical and healthcare field the accurate analysis of medical data has been the benefit of early patient care. With the help of disease data, data mining finds hidden pattern information in a huge amount of medical data. We proposed general disease prediction based on the symptoms of the patient. For disease prediction, we use K-Nearest Neighbor (KNN) and Convolutional neural network (CNN) machine learning algorithms for the accurate prediction of disease. Disease prediction required a disease symptoms dataset. In this general disease prediction, the living habits of a person and checkup information consider for the accurate prediction. The accuracy of general disease prediction by using CNN is 84.5% which is more than the KNN algorithm. And the time and the memory requirement are also more in KNN than in CNN. After general disease prediction, this system can give the risk associated with the general disease which is a lower risk of general disease or higher. Keywords: KNN, CNN and Healthcare

Abstract: Due to the rise of Coronavirus Pandemic, the majority of people were forced to follow a lot of protocols from masks and social distancing to online presence at work places. One of those places are educational institutions. The lectures could be easily conducted using online video conferences, but exams are very difficult to be conducted online. And the part that makes it hard is invigilation of those exams. Invigilation is a very important part of any examination. Even though it is evident that examinations are for the candidates to evaluate their performance, they still try to cheat to get good results which may get them benefits they do not deserve. We propose a system that proctors or invigilates students while giving online exams. The system collects candidates' behavior projected on the camera at browsers and extracts information from those images, like ‘looking left’, ‘missing test’ etc. and logs them to a SQL database. The system also has a threshold for fouls candidate commits and would submit the exam when threshold is crossed.

Authors: Muher Sukmayanto  , Tubagus Hasanuddin  , Listiana Indah
Published: May 2022

Rice is an important commodity and the availability of rice supply in Indonesia must be maintained, because rice is the staple food of the Indonesian people which must always be fulfilled at all times. However, the fact is that the average productivity of rice produced by farmers is still low. Low rice productivity reflects the capacity of farmers in rice farming. The aims of this research are: (1) to know the level of farmer's capacity? and (2) to find out what factors that affect the capacity of farmers. This research was conducted in Kabupaten Lampung Tengah with the number of respondents as many as 100 farmers. The data analysis method used is multiple regression analysis. The results showed that the level of farmer's capacity was in the medium category. Factors that have a significant effect on farmer’s capacity are farmer’s’ age, farming experience, farmer’s motivation, community support, farmer group support, and agricultural extension support, while formal education, non-formal education, cosmopolitan level, land area, and family support have no significant effect on the capacity of farmers in rice farming.

Authors: Maulida Nur Isnaini  , Agustono  , Umi Barokah
Published: May 2022

Development is a long-term process of change to improve regional welfare. The regional economic development indicator is GRDP. The former Madiun residencies have the lowest average of GRDP. Accordingly, the economic development activities and effort to mitigate income inequality should be carried out properly. Using MRT, Williamson Index, and Shift Share analysis, the research results on agricultural, forestry and fisheries sectors of the former Madiun residencies include the basic and non-basic sectors. The basic-sector former residencies of Madiun include the regencies of Pacitan, Ponorogo, Madiun, Magetan, and Ngawi. Meanwhile, the non-basic sector ex-residence is the City of Madiun. The results of the Williamson Index show that the agricultural sector has a role in reducing income inequality. The IW value of ex-residencies with the agricultural sector has an average of 0.39, and the one without the agricultural sector is 0.53. As for the shift-share, the results show that the national share component of all sub-sectors is positive, meaning that sub-sector is experiencing growth. The industrial mix of all sub-sectors is negative (IM<0), meaning that sub-sector growth in former Madiun residencies is slow. The competitive share has positive value (CS>0), meaning that it has good sub-sector competitiveness and can develop.
Factors Affecting Delivery Performance of Pamarican District Farmers' Unhulled Rice Grain Supply Chain System of Ciamis Regency with PT Mitra Desa Pamarican
Authors: Helbawanti Octaviana , Dwi Apriyani
Published: May 2022

One of the problems in fulfilling the staple food consumption of rice in Indonesia is the rice distribution system. Delivery performance is one of the important measurements in the supply chain system since it is an indicator of the accuracy of the quantity and time of grain delivery from rice farmers involved in partnership with PT MDP. Respondents used in this study consisted of 30 rice farmers chosen through purposive sampling technique in Pamarican District, Ciamis Regency, West Java. The analytical method used is multiple linear regression or multiple linear regression model with Ordinary Least Square to analyze the influence of the distance of the farmer to the grain collection point, the length of time the farmer makes inventory, the experience of farming, the farmer's storage capacity, and the method of payment for grain or the transaction system on the delivery performance. The results of the analysis show the variables of distance, inventory, and transaction systems. The distance variable has a significant positive effect, the inventory variable has a significant negative effect, and the cash transaction system will improve the delivery performance of farmers to PT MDP. Farmers make cost efficiency for grain delivery by collecting grain first. A decrease in delivery performance occurs when farmers store the grain longer
The Economic Impact of Climate Change on the Local Apple
Authors: Ariadi Bambang Yudi
Published: May 2022

An unavoidable climate change has an impact on agricultural production.  This study aims at determining farmers’ knowledge concerning climate change and farmers’ behavior in apple cultivation, as well as it aims at investigating the impact of climate change on apple productivity, environmental damage, and apple prices. Primary data were collected using structured interviews to farmers of apple. Structural Equation Model (SEM) is employed to analyze the effect of climate change on production, environment and price changes. The results showed farmers possessed knowledge concerning climate change based on information mainly received from television and their perceived experience. Climate change causes the increase of warmer air temperatures, drought, and the need for product facilities, like fertilizers and pesticides. However, it causes the decrease of apple production. Climate change has a significant negative effect on apple productivity and the economic value of apples. The environment also has a negative effect on apple productivity at a lower level of significance.  During climate change, apple productivity has a negative effect on apple prices, It means that the higher the apple productivity is, the lower the apple price will be. Hence, climate change caused the impact of a decrease in the economic value of local apple agribusiness in Malang Raya.

Re-examining the quantum volume test: Ideal distributions, compiler optimizations, confidence intervals, and scalable resource estimations
Authors: Baldwin Charles H. , Mayer Karl , Brown Natalie C. , Ryan-Anderson Ciarán , Hayes David
Published: May 2022

The quantum volume test is a full-system benchmark for quantum computers that is sensitive to qubit number, fidelity, connectivity, and other quantities believed to be important in building useful devices. The test was designed to produce a single-number measure of a quantum computer's general capability, but a complete understanding of its limitations and operational meaning is still missing. We explore the quantum volume test to better understand its design aspects, sensitivity to errors, passing criteria, and what passing implies about a quantum computer. We elucidate some transient behaviors the test exhibits for small qubit number including the ideal measurement output distributions and the efficacy of common compiler optimizations. We then present an efficient algorithm for estimating the expected heavy output probability under different error models and compiler optimization options, which predicts performance goals for future systems. Additionally, we explore the original confidence interval construction and show that it underachieves the desired coverage level for single shot experiments and overachieves for more typical number of shots. We propose a new confidence interval construction that reaches the specified coverage for typical number of shots and is more efficient in the number of circuits needed to pass the test. We demonstrate these savings with a QV=210 experimental dataset collected from Quantinuum System Model H1-1. Finally, we discuss what the quantum volume test implies about a quantum computer's practical or operational abilities especially in terms of quantum error correction.
Jet: Fast quantum circuit simulations with parallel task-based tensor-network contraction
Authors: Vincent Trevor , O'Riordan Lee J. , Andrenkov Mikhail , Brown Jack , Killoran Nathan , Qi Haoyu , Dhand Ish
Published: May 2022

We introduce a new open-source software library Jet, which uses task-based parallelism to obtain speed-ups in classical tensor-network simulations of quantum circuits. These speed-ups result from i) the increased parallelism introduced by mapping the tensor-network simulation to a task-based framework, ii) a novel method of reusing shared work between tensor-network contraction tasks, and iii) the concurrent contraction of tensor networks on all available hardware. We demonstrate the advantages of our method by benchmarking our code on several Sycamore-53 and Gaussian boson sampling (GBS) supremacy circuits against other simulators. We also provide and compare theoretical performance estimates for tensor-network simulations of Sycamore-53 and GBS supremacy circuits for the first time.

Jeremy Waldron e a sabedoria da multidão: a importância do Legislativo na resolução de desacordos de moralidade política
Authors: Casimiro Matheus
Published: May 2022

atualmente, nos Estados que adotam Constituições rígidas e um controle jurisdicional de constitucionalidade forte, o Legislativo é visto com desconfiança enquanto as Cortes Constitucionais são tidas como um reduto de mestres da argumentação moral. Nesse cenário, ainda há razões para defender o protagonismo legislativo na resolução dos principais desacordos de moralidade política da sociedade? O presente trabalho analisa a crítica de Jeremy Waldron à visão utópica do Judiciário, apresentando os argumentos do autor em prol da sabedoria da multidão, que estaria presente no Legislativo. Como metodologia, utiliza-se o estudo bibliográfico, com ênfase nos argumentos apresentados por Waldron no livro A Dignidade da Legislação. Com base na análise realizada, constata-se que o Legislativo, mesmo que não seja composto por sábios eruditos, pode apresentar um significativo ganho epistêmico em virtude da diversidade de sua composição, sendo necessário ressaltar seu importante papel na resolução de desacordos morais da sociedade.

Track Association Based on the Empirical Mode Decomposition in Passive Localization
Authors: Lu Kai , Qi Chundong
Published: May 2022

In distributed passive localization and tracking system, the track
observed by the subsystem seems like Brownian motion track, because the
tracked target is non-cooperative target and its maneuver is often
complex, and the localization accuracy is poor. These track
characteristics will seriously disturb track association between
different subsystems. In order to solve this problem, the track to track
association algorithm based on empirical mode decomposition (EMD) is
proposed in this letter. Each dimension data of the track from each
subsystem is processed by EMD and the high frequency components are
eliminated. A track motion trend (MT) vector is created by collecting
the rest components of the processed data. For these vectors, the
corresponding rule is constructed, in which the association threshold is
self-adaptive, and the assumption of the target motion model is not
required. The simulation results show that the proposed algorithm can
accomplish track association effectively in passive localization
systems.

Published: May 2022

The rapid development of free and open access hydrological models and
coupling frameworks tools continue to present more opportunities for
coupled model development for improved assessment of floodplain
hydrology. In this study, we set up a The Upper Zambezi Hydrological
model and a fully spatially hydrological-hydrodynamic coupled model for
the Barotse Floodplain using GLOFRIM (GLObally applicable computational
FRamework for Integrated hydrological–hydrodynamic Modelling). The
hydrological and hydrodynamic models used are WFLOW and LISFLOOD-FP
respectively. The simulated flows generated by wflow model for the
upstream gauge stations before the Barotse Floodplain, were quite
similar and closely matched the observed flow as indicated by the
evaluation statistics; Chavuma, nse=0.738; kge = 0.738; pbias = 2.561
and RSR = 0.511; Watopa, nse=0.684; kge = 0.816; pbias = 10.577 and RSR
= 0.557; Lukulu, nse=0.736; kge = 0.795; pbias = 10.437 and RSR = 0.509.
However, even though wflow hydrological model was able to simulate the
upstream hydrology very well, the results at the floodplain outlet gauge
stations did not quite match the observed monthly flows at Senanga gauge
station as indicated by the evaluation statistics: nse=0.132; kge =
0.509; pbias = 37.740 and RSR = 0.9233. This is mainly because the
representation of both floodplain channels hydrodynamics and vertical
hydrological processes are necessary to correctly capture floodplain
dynamics. Thus, the need for an approach that saves as a basis for
developing a fully spatially distributed coupled hydrodynamic and
hydraulic models’ assessments for groundwater dependent tropical
floodplains such as the Barotse floodplain, in closing the gap between
hydrology and hydrodynamics in floodplains assessments. A fully model
coupling has the potential of been used in implementing adaptive wetland
management strategies for water resources allocation, environmental flow
(eflows), flood control, land use and climate change impact assessments.
A note on the MHD flow in a porous channel
Authors: Marusic-Paloka Eduard , Pazanin Igor
Published: May 2022

In this paper we study the flow of a viscous incompressible conducting fluid through a corrugated channel filled with a porous medium. The fluid flow in the channel is under the action of the transverse magnetic field and driven by the pressure drop between the channel?s edges. Using boundarylayer analysis, we derive a higher-order asymptotic model taking into account the inertia and roughness-induced effects on the filtration velocity.
The Contagion Reputational Effects of Failed Individual Audit Partners: Evidence from an Audit Client Market
Authors: Gul Ferdinand A. , Lim Chee Yeow , Wang Kun , Xu Yanping
Published: May 2022

Prior research using individual auditor data shows that the stock market punishes the clients of failed auditors but not those of nonfailed auditors in the same tainted office (e.g., Li, Qi, Tian, and Zhang 2017). In this study, using audit client market share, we find similar results, but, more importantly, we document that the nonfailed partners’ client market shares decrease when they lack a track record to infer their audit quality credentials and when they reveal connections through teamwork experience with failed audit partners. In other words, nonfailed auditors in the same tainted office suffer contagion loss if there are no mitigating circumstances, such as a good track record or dissociation with failed auditors. These findings are novel in the literature and contribute to the empirical evidence for contagion effects in an individual partner reputational environment.

Sosiaalialan ammattilaisten kyvykkyys tietojärjestelmien käyttäjinä ja kokemukset tietojärjestelmien tuesta työlle
Authors: Salovaara Samuel , Hautala Sanna , Silén Marianne
Published: May 2022

Sosiaalialan korkeakoulutettujen ammattilaisten kokemuksia kartoitettiin nyt ensimmäistä kertaa osana valtakunnallista Sosiaali- ja terveydenhuollon tietojärjestelmäpalveluiden seuranta ja arviointi (STePS 3.0) -hanketta. Tutkimuksen tavoitteena on tuottaa tietoa Sote-tieto hyötykäyttöön -strategiassa määriteltyjen tavoitteiden toteutumisesta sosiaalialan ammattilaisten osalta. Tutkimuksessa kysyttyiin, miten kokeneita ja osaavia sosiaalialan ammattilaiset ovat tietojärjestelmien käyttäjinä, miten tietojärjestelmät tukevat sosiaalialan ammattilaisten tiedonhakua ja -vaihtoa ja miten hyvin asiakastietojärjestelmät tukevat sosiaalialan ammattilaisten työtä.
Tutkimusaineisto muodostui sähköiseen kyselylomakkeeseen syys-lokakuussa 2020 vastanneiden 990 sosiaalialan ammattilaisen vastauksista, jotka työskentelivät julkisella, yksityisellä tai kolmannella sektorilla moninaisissa sosiaalialan työtehtävissä. Tulosten mukaan sosiaalialan korkeakoulutetut ammattilaiset ovat kokeneita tietojärjestelmien käyttäjiä, mutta järjestelmien tarjoama tuki työlle on paikoitellen heikkoa. Julkisella sektorilla työskentelevien sosiaalialan ammattilaisten arviot tietojärjestelmien tarjoamasta tuesta työlle olivat kriittisempiä muihin sektoreihin verrattuna. Tietojärjestelmiä hyödynnetään tiedonhaussa pääasiallisena asiakastiedon lähteenä, mutta edelleen turvaudutaan myös vanhanaikaisiin ja tietoturvaltaan heikkoihin tiedon haun menetelmiin. Sosiaalihuollon asiakastiedon arkistoa ei vielä juurikaan hyödynnetä sosiaalialalla tiedonhaussa. Tutkimus nostaa esiin tarpeen tunnistaa tietojärjestelmien hyödyntämistä vaikeuttavat esteet sekä huomioida sosiaalialan vuorovaikutukseen ja sosiaalisiin verkostoihin kiinnittyvä käytäntö sekä erilaisiin ammatillisiin työtehtäviin liittyvät tarpeet paremmin tietojärjestelmien kehityksessä, jotta tietojärjestelmät voisivat jatkossa paremmin tukea sosiaalialan ammattilaisia heidän päivittäisessä työssään.
Terveydenhuollon digitaalisten tietojärjestelmien vaikutus hoitohenkilöstöön ja potilastuloksiin: Kartoittava kirjallisuuskatsaus hoitotyön näkökulmasta
Authors: Valkeapää Ella , Peltonen Laura-Maria
Published: May 2022

Tämän kartoittavan kirjallisuuskatsauksen tarkoituksena oli koota tutkimusnäyttöä terveyspalveluiden digitaalisten tietojärjestelmien vaikuttavuudesta hoitohenkilöstöön ja potilastuloksiin. Sisäänottokriteerit olivat: tutkimus käsittelee terveydenhuollon digitaalista tietojärjestelmää, joka on käytössä kliinisessä työssä sekä sen vaikutusta hoidon laatuun, hoitohenkilöstön tai potilaiden tyytyväisyyteen, toiminnan tehokkuuteen, hoidon tuloksiin, työn prosessiin tai hoidon kustannuksiin. Pois jätettiin viivakodin lukijat, johtamisen tietojärjestelmät ja mobiililaitteita käsittelevät tutkimukset, sekä tekoälyyn, herätteisiin, asioiden internetiin ja robotiikkaan pohjautuvat tutkimukset. Tiedonhaussa käytettiin neljää tietokantaa: CINAHL, Cochrane Library, PubMed ja Web of Science. Tuloksena löytyi 2400 artikkelia, joista 16 otettiin mukaan tutkimukseen. Artikkelit oli julkaistu vuosina 1995–2020. Tulokset analysoitiin deduktiivisella sisällönanalyysillä.
Neljä tukimusta oli tehty kokeellisella asetelmalla ja 12 oli tehty kvasikokeellisella asetelmalla. Tutkimusten laatupisteet olivat keskinkertaisia. Tietojärjestelmistä käytetyt termit muodostivat yläkategoriat: Potilasasiakirja, lääkehoidon prosessi, tiedon automaattinen tallennus sekä potilasportaali. Suurin osa tutkimuksista keskittyi potilasasiakirjoihin. Järjestelmien päätehtäviä olivat lääkehoidon prosessin tukeminen ja digitaalinen hoitotyön kirjaus. Digitaalisia tietojärjestelmiä verrattiin paperisiin järjestelmiin ja dataa kerättiin kyselylomakkeilla tai aika- ja liikeanalyysin avulla. Hoitohenkilöstön tuloksiin liittyen tutkituimpia aiheita olivat ajankäyttö ja tyytyväisyys, joiden suhteen tulokset jäivät ristiriitaisiksi. Potilastulokset eivät tulleet aineistossa esiin laajasti. Neljässä potilastuloksia koskevassa tutkimuksessa havaittiin kuitenkin niin positiivisia kuin negatiivisia vaikutuksia.
Tulosten perusteella voidaan todeta, että näyttö digitaalisen tietojärjestelmien vaikutuksesta henkilöstöön ja potilastuloksiin on vielä vähäistä ja digitaalisten tietojärjestelmien terminologia ja määritelmät ovat hajanaisia. Korkeatasoista näyttöä vaikuttavuudesta käytännön ympäristössä tarvitaan enemmän erityisesti siitä, miten tietojärjestelmät vaikuttavat potilastuloksiin.
Kohti käyttäjälähtöisiä kotidialyysin sähköisiä terveyspalveluita: Potilaskokemus ja ammattilaisten tarpeet suunnittelun lähtökohtana

Uuden kotidialyysihoidon sähköisen palvelun tavoitteena on sujuvoittaa ja tukea potilaiden hoitoa. Palvelun loppukäyttäjien huomioiminen ja osallistaminen kehittämistyöhön on tärkeää, jotta palvelu voidaan ottaa laajasti käyttöön ja se koetaan hyödylliseksi.
Tässä artikkelissa kuvataan tutkimus, jonka tavoitteena oli selvittää kotidialyysipotilaiden ja heitä hoitavien ammattilaisten tarpeita ja kokemuksia uudelle kehitettävälle sähköiselle ratkaisulle, joka sisältää sovelluksen ja erilaisia mittareita. Tutkimus on osa monialaista ’Terveysteknologia predialyysi- ja kotidialyysihoidossa’ -tutkimushanketta. Tutkimusaineisto kerättiin kahdesta etäjärjestelyin toteutetusta työpajasta, joihin osallistui vuoden 2021 lopussa yhteensä viisi potilasta ja neljä ammattilaista. Työpajojen suunnittelussa hyödynnettiin tutkimusprojektissa aiemmin kerättyä laajaa haastattelu- ja arviointitutkimusaineistoa. Työpaja-aineistot analysoitiin laadullisin menetelmin.
Potilailla oli jonkin verran käyttökokemusta uudesta kotidialyysin sähköisestä ratkaisusta. Potilaat näkivät mittareista ja sovelluksesta koostuvassa kokonaisuudessa paljon potentiaalia. He kokivat tärkeänä mahdollisuudet omien mittaustulosten seurantaan ja tietoperusteiseen hoitoon liittyvään päätöksentekoon. Potilaiden mielestä jatkuva mittaaminen ja kyselyiden täyttäminen oli kuitenkin ajoittain raskasta. Lisäksi he kokivat älyrannekkeen käytettävyyden heikoksi.
Ammattilaiset olivat tietoisia uudesta sähköisestä ratkaisusta, mutta heillä ei vielä ollut kokemusta sen käytöstä. Ammattilaisten näkökulmasta uuden ratkaisun tulee istua osaksi nykyistä teknistä työskentely-ympäristöä. Ratkaisun potentiaalisina hyötyinä nähtiin erityisesti potilaan kokonaiskuvan hahmottaminen ja potilaiden tilan seuraaminen yhdessä potilaiden kanssa. Ammattilaiset toivoivat käyttöönoton tueksi lisäresursseja ja opastusta.
Kehitettävässä kotidialyysin sähköisessä palvelussa nähdään olevan potentiaalia, mutta sen laajempaan käyttöön liittyen on tärkeää suunnitella ja sopia toimintatavat ammattilaisten ja potilaiden välillä. Palvelun jatkokehityksessä tulee kiinnittää huomioita käytettävyyteen ja yhteentoimivuuteen nykyisten sovellusten ja järjestelmien kanssa, jotta uuden palvelun käyttö on sujuva ja luonteva osa hoitoa sekä potilaiden että ammattilaisten näkökulmasta. Tulevaisuudessa sähköisten palveluiden avulla voidaan rohkaista useampia potilaita valitsemaan kotihoito kalliimman ja vähemmän yksilöidyn sairaalahoidon sijaan.
Haz de cuenta (que) como marcador discursivo del español de México. Un estudio de variación pragmática a partir del análisis de corpus.
Authors: Guillén Escamilla Josaphat Enrique
Published: May 2022

Este trabajo tiene como objetivo analizar el comportamiento del marcador discursivo haz de cuenta (que) considerando la influencia de los factores sociales: región geográfica, sexo, edad y nivel de instrucción. En particular, se busca: (i) determinar cuál es la distribución geográfica de este marcador en distintas variedades del español, (ii) describir la influencia del sexo, la edad y el nivel de instrucción en su empleo en el español de la Ciudad de México y (iii) caracterizar sus funciones discursivas. Para tales fines, se analizan los corpus PRESEEA (2014), Ameresco (Albelda & Estellés 2021) y el Corpus Sociolingüístico de la Ciudad de México (Martín Butragueño & Lastra 2011, 2012, 2015). Los resultados señalan que este marcador es propio de la variante del español de México y, como tal, puede desempeñar cuatro funciones: (i) ejemplificación, (ii) reformulación, (iii) representación y (iv) continuativo. En cuanto a la influencia de las variables sociales, en el español de la Ciudad de México, son los jóvenes y el nivel de instrucción medio quienes privilegian su uso, en tanto que mujeres y hombres muestran un comportamiento bastante homogéneo en su empleo. Finalmente, se concluye que haz de cuenta (que) es una marca dialectal del español de México que se ha desarrollado en los años recientes.
“En el 8 de marzo nos dan calor”. Memorias de expresas políticas uruguayas en la primavera feminista
Authors: De Giorgi Ana Laura
Published: May 2022

Este artículo tiene como principal objetivo analizar los modos de las expresas políticas de Uruguay de narrar el pasado e intervenir en el espacio público en el contexto de un nuevo momento feminista. El texto parte de la inquietud por comprender la interpelación que el movimiento feminista actual lleva a cabo en un colectivo de expresas políticas organizadas en torno a la denuncia de violencia sexual y la construcción de un memorial para presas políticas. Se detiene especialmente en los lugares de enunciación y en el acercamiento a un lenguaje feminista. En términos conceptuales, busca lograr un aporte articulando dos campos de estudio: la memoria y los estudios de género; en términos histórico-políticos: tender un puente, siempre inestable, entre el movimiento de los derechos humanos y el feminista. Las fuentes que se analizan son los testimonios orales de expresas políticas desplegados en los últimos dos años en Uruguay.
