Sosiaaliset verkostot ovat yksilöiden ja ryhmien välisiä sidoksia, jotka kuvaavat sosiaalisiin suhteisiin ja aktiviteetteihin osallistumista. Sosiaaliset verkostot edistävät terveyttä, esimerkiksi syöpäpotilailla verkostojen on todettu olevan yhteydessä hyvinvointiin ja vähentyneeseen kuolleisuuteen.
Mittasimme Oulun ylipistolliseen sairaalaan (OYS) hoitoon tulleiden uusien rintasyöpä- (n=222) ja lymfoomapotilaiden (n=102) sosiaalisia verkostoja 2–5 kuukautta diagnoosin jälkeen sekä 9, 18 ja 36 kuukauden kuluttua. Kysyimme verkostojen henkilömäärää ja kuinka monen kanssa potilas oli puhunut syövästään seuraavissa osaverkostoissa: puoliso, perhe, lähipiiriin kuuluvat omaiset (aikuiset lapset perheineen, omat/puolison vanhemmat, omat/puolison sisarukset, tätä kaukaisemmat sukulaiset), läheiset ystävät, tuttavat, muut syöpäpotilaat, syöpää hoitaneet henkilöt, työyhteisö, muut hoitosuhteet, osallistuminen (uskonnollinen yhteisö, harrastukset, järjestötoiminta).
Alkuvaiheessa lähes 90 %:lla oli puoliso/kumppani, neljäsosalla kotona asuvia lapsia ja kaikilla joitakin lähipiiriin kuuluvia omaisia. Kolmella neljästä oli aikuisia lapsia perheineen (nuoremmilla useammin omia/puolison vanhempia, vanhemmilla aikuisia lapsia puolisoineen ja lastenlapsia) ja lähes kaikilla sisaruksia. Useimmilla oli ystäviä. Em. lähiverkostot olivat tyypillisesti laajoja ja kaikille oli yleensä puhuttu syövästä. Neljä viidestä oli jo alkuvaiheessa puhunut tuttaville ja muille syöpään sairastuneille. Työssä olevat olivat yleensä puhuneet työyhteisössään. Seurannassa jotkin osaverkostot harvinaistuivat ja supistuivat hiukan, rintasyöpäpotilailla enemmän kuin lymfoomapotilailla, mutta lähipiiriin kuuluvien kaukaisempien sukulaisten ja ystävien määrä suureni alkuvaiheen ja yhdeksän kuukauden välillä. Muiden syöpäpotilaiden määrä lisääntyi koko ajan.
Sairastuneilla oli paljon ja laajoja sosiaalisia verkostoja, joissa varsinkin läheisille oli puhuttu syövästä. Lähiverkostot olivat eri-ikäisillä erilaisia. Sairastumisen jälkeen lähipiiriin tuli lisää sukulaisia ja ystäviä, ja verkostoihin liittyi kanssapotilaita ja hoitoon osallistuvia. Vaikka osaverkostot saattoivat seurannassa vähentyä, tätä tapahtui hyvän ennusteen omaavassa syövässä (rintasyöpä) enemmän kuin vakavammassa (lymfooma). Tulkitsemme, että jälkimmäisillä oli suurempi tarve ylläpitää tukea antavia ihmissuhteita.
Kuntoutukseen osallistumisen sosioekonomiset erot - rekisteritutkimus oululaisista vuonna 2018
Authors: Rinne Hanna , Blomgren Jenni
Published: March 2022

Kuntoutukseen osallistumisen sosioekonomisista eroista on vain vähän tietoa. Tavoitteena oli selvittää, millaisia eroja kuntoutukseen osallistumisessa on ylipäätään ja eri osajärjestelmissä koulutuksen, ammattiaseman ja tulojen mukaan sekä selittyvätkö kunkin sosioekonomisen aseman mittarin mukaiset erot muilla sosioekonomisen aseman mittareilla, siviilisäädyllä ja sairastavuudella. Aineistona oli rekisteriaineisto Oulussa vuonna 2018 asuneista 25–64-vuotiaista (N=99569) sekä heidän sosiaali- ja terveyspalveluiden ja etuuksien käytöstään. Kuntoutukseen osallistuneiksi määrittelimme kaikki julkisen terveyspalvelujärjestelmän, Kelan tai työeläkelaitosten kuntoutukseen tai työterveyshuollon tai yksityiseen fysioterapiaan vuoden 2018 aikana osallistuneet. Menetelminä käytimme ristiintaulukointia ja logistista regressioanalyysia.
Kuntoutukseen osallistuminen oli keskimääräistä harvinaisempaa perusasteen koulutuksen saaneilla, yrittäjillä ja työttömillä sekä alimmassa tuloneljänneksessä, kun ikä ja sukupuoli oli huomioitu. Siviilisäädyn, muiden sosioekonomisten ja sairastavuuteen liittyvien taustatekijöiden vakioiminen ei juuri muuttanut tuloksia. Julkisen terveyspalvelujärjestelmän järjestämään kuntoutukseen osallistuivat todennäköisimmin työelämän ulkopuolella olevat ja pienituloiset. Kelan kuntoutukseen osallistuneiden profiili oli samankaltainen, mutta lisäksi Kelan kuntoutukseen osallistuivat todennäköisimmin korkeasti koulutetut ja ylemmät toimihenkilöt. Työeläkekuntoutukseen osallistuivat todennäköisimmin keskiasteen suorittaneet, opiskelijat ja muut työelämän ulkopuolella olevat sekä keskituloiset. Työterveyshuollon fysioterapiaan ja yksityiseen fysioterapiaan osallistuivat todennäköisimmin korkeasti koulutetut, palkansaajat sekä hyvätuloiset; yksityiseen fysioterapiaan usein myös yrittäjät.
Matalimmassa sosioekonomisessa asemassa olevilla on muita pienempi todennäköisyys osallistua kuntoutukseen. Kohdentuessaan hyväosaisille kuntoutus saattaa osin ylläpitää väestön sosioekonomisia terveyseroja. Kuntoutuksen sosioekonomisista eroista saatavaan kuvaan vaikuttaa kuitenkin se, mikä kaikki kuntoutus tutkimuksessa on mahdollista huomioida.
Social Media and the COVID-19: South African and Zimbabwean Netizens’ Response to a Pandemic
Authors: Mutanga Murimo Bethel , Ureke Oswelled , Chani Tarirai
Published: March 2022

Since the end of 2019, the world faced a major health crisis in the form of the Coronavirus (COVID-19) pandemic. To mitigate the impact of the pandemic, governments across the globe instituted measures such as restricting local and international travel and in many cases, ordering citizens to stay indoors. Considering the social and economic impact of these restrictions it becomes crucial to investigate internet citizens’ (netizens) perception about the precautionary measures adopted. The study is anchored in the digital public sphere theory, which treats social media applications as virtual platforms where netizens commune to share ideas and debate about issues that affect them. Social media platforms already have critical public views on the current pandemic. However, the majority of this data is unstructured and difficult to interpret. Natural language processing (NLP), on the other hand, makes the task of gathering and analysing vast amounts of textual data feasible. Extracting structured knowledge from natural language, however, comes with unique challenges due to diverse linguistic properties including abbreviation, spelling mistakes, punctuations, stop words and non-standard text. In this work, The Latent Dirichlet Allocation (LDA) algorithm was applied to tweeter data to extract topics discussed by netzens from Zimbabwe and South Africa.  The primary focus of this paper, is to comparatively explore the variety of topics that occupied twitter communities from the two countries. We examine whether or not the national identities that define and differentiate citizens of these countries also exist on Twitter as evident in the emerging topics. Furthermore, this work investigated public opinion by analysing how citizens discuss the issues around the COVID-19 pandemic on social media

Published: March 2022

Nowadays, it is essential to use all concepts of Human-Computer interaction to understand mobile application design usability. This manuscript aimed to analyze a mobile application user experience (Grab online transportation), especially Grab foodservice users, using a user experience questionnaire since we noticed some Grab food users' complaints.  Researchers collected data from 90 respondents within six were not used because the excel data analysis tool found that there were suspicious. We finally analyzed using an excel data analysis tool. The findings have shown that all six scales of the User Experience Questionnaire (UEQ) are good except the dependability scale. In addition, the mean scale value computed is favorable, and all values are more significant than 0.8 compared to the UEQ benchmark. The findings can be used for dependability improvement to reduce complaints from users.

Authors: Pradnya Sidhawara Aloysius Gonzaga
Published: March 2022

One of the influential learning resources utilized today is a web-based learning management system. The web-based e-learning’s usability is also influenced by the user interface. In measuring usability, eye-tracking technology can be employed to examine eye gaze of an individual when looks at a specific point at a certain time. The use of eye-tracking is beneficial in obtaining objective data. This study aims to evaluate the usability of UAJY Learning Management System website interface and examine the user's interaction with the website interface. Thirty-five participants were recruited in a usability testing experiment. Participants were asked to do three tasks related to the use of e-learning features while their eye movements were recorded. The USE Questionnaire and task-related question data were processed using statistical descriptive methods and eye movement data generated into heatmaps. The Usefulness, Ease of Use, Ease of Learn, and Satisfaction aspects of the UAJY LMS gains more than 80% feasibility percentage. Overall results of feasibility categorized the UAJY LMS as Very Feasible. There was no difference found in usability aspects between gender, faculty background, and eye condition groups. Heatmaps results show that navigational elements in the LMS are utilized properly and successfully help participants in performing tasks.

Published: March 2022

Artificial intelligence has developed in various fields. The development became more significant after Neural Networks(NN) began to gain popularity. Convolutional Neural Networks(CNNs) are good at solving problems such as classification and object detection. However, the CNNs model tends to function to solve a specific problem. In the case of both object detection and face recognition it is difficult to make a single model that works well. NoonGil Lens+ is expected to be an approach that can solve both problems at once. As well as being a solution, it is also hoped that this approach can reduce the trade-off of accuracy and execution speed. The approach we propose can be called as Noongil Lens+, a system that connects YOLOv3 and FaceNet. It is inspired from a korean series called ‘STARTUP’. The author only develops the FaceNet model and the proposed system in this paper (NoonGil Lens+). Region Selection, a machine learning-based greedy approach was proposed to determine snapshots to fed into FaceNet for facial identity classification. FaceNet is trained on the CelebA dataset which has gone through the preprocessing process and is validated using the LFW dataset. NoonGil Lens+ was validated using 70 images of 7 celebrities, characters, and athletes. In general, the research was carried out successfully. NoonGil Lens+ using Region Selection has an accuracy of up to 75.2%. The Region Selection execution speed is also faster compared to Cascade Faces.

Authors: Vakili-Ghartavol Masoumeh , Arouiee Hossein , Golmohammadzadeh Shiva , Naseri Mahboobeh
Published: March 2022

The objective of this study was to investigate the chemical composition and in vitro antifungal activity of Mentha × Piperita L. (peppermint) essential oil (EO) against some plant pathogenic fungi (Alternaria alternata, Penicillium expansum, Rhizoctonia solani, and Rhizopus stolonifer). Antifungal activity of EO against the selected fungi was conducted using the agar diffusion method by adding peppermint EO concentrations (0, 250, 500, 750, 1000, and 2000 ppm). The gas chromatography-mass spectrometry (GC-MS) analysis of peppermint EO showed that the main constituent was menthol (36.4%), followed by menthone (27.7%) and menthyl acetate (11.2%). The mycelium growth of the selected fungi was significantly inhibited by peppermint EO. Light and electron microscopy studies showed that mycelium morphology was seriously changed after treatment with peppermint essential oil. The level of malondialdehyde illustrated that peppermint EO led to lipid peroxidation in the fungal pathogens. Therefore, due to its antifungal properties, peppermint EO can be used as an additive in the food industry and as an active substance in pharmaceuticals.
Evaluating chemical and thermal weed suppression in lemon balm (Melissa officinalis L.) cultivation
Authors: Borowy Andrzej , Kapłan Magdalena
Published: March 2022

The usefulness of 3 herbicides and flame weeding in lemon balm sown directly into the field was assessed in a two-year experiment. Glufosinate-ammonium (600 g∙ha–1) and flame weeding (90 kg propane∙ha–1) were applied 12–13 days after lemon balm sowing, i.e. shortly after weed emergence and 4 days before crop emergence. Bentazon (960 g∙ha–1) and fluazifop-P-butyl (150 g∙ha–1) were sprayed approximately 3 weeks after sowing, during the emergence of lemon balm, and when the weeds were in the cotyledon – 2–4 true leaves stage. All of the studied weed control methods significantly reduced the number and fresh weight of weeds growing 4 weeks after lemon balm sowing. The most effective method was spraying with glufosinate-ammonium, which controlled 69–76% of weeds. The efficiency of flame weeding was slightly lower. Bentazon caused slight, temporary chlorosis of some lemon balm cotyledons. Content of essential oil (1.9–2.1%), its composition and content of rosmarinic acid (2.08–2.44%) in lemon balm leaves, as well as content of total nitrogen (2.18–2.55%), phosphorus (0.30–0.32%), potassium (2.94–3.22%), calcium (1.02–1.60%), and magnesium (0.30–0.32%) in lemon balm raw material were independent of the weeding method. Content of essential oil, phosphorus, potassium and calcium were significantly higher in the dryer year. Studied weed control methods proved useful in the cultivation of lemon balm from direct sowing into the field. Methods with total action (flaming and glufosinate-ammonium) were more effective than those with selective herbicides (bentazon and fluazifop-P-butyl).

Published: March 2022

The present study was carried out during both 2018 and 2019 growing seasons on ‘Crimson Seedless’ grape vine grown on sandy soil. Vines received water, salicylic acid 200 mg/L, chitosan 10 g/L, putrescine 5 mM, phenylalanine 400 mg/L, ascorbic acid 500 mg/L, citric acid 700 mg/L, gibberellic acid 20 mg/L, active dry yeast 15 g/L at véraison (change of color) stages and at 10 days before harvesting time. Fruit clusters were harvested when total soluble solids (TSS) reached 16%, stored at 0°C and 85–90 relative humidity for 35 days then kept 2 days at shelf life (25 ±2°C and air humidity 70 ±2). Results at harvest time showed that, salicylic acid, putrescine, gibberellic acid and yeast increased average berry weight and juice volume. Salicylic acid, chitosan, putrescine, citric acid and gibberellic acid maintained the berry adherence strength and firmness. Salicylic acid, chitosan, putrescine and phenylalanine increased berry red color, as well as berry anthocyanin, TSS and sugars content. Highest acidity content was obtained by salicylic acid, chitosan, citric acid and gibberellic acid spraying. Results after cold storage and shelf life showed that, berry weight loss decreased significantly by all chemical sprays, except phenylalanine. High maintenance of berry adherence strength and firmness occurred by gibberellic acid followed by putrescine. All chemicals reduced the unmarketable grapes except the phenylalanine.
Effects of vine water status on vine performance and grape composition of (Vitis vinifera L.) cv. 'Sultani Çekirdeksiz'
Authors: Soltekin Oguzhan , Altındisli Ahmet
Published: March 2022

Drought caused by climate change increased the relevance of irrigation management in viticulture. In order to regulate irrigation strategies for Vitis vinifera L., their influences on vine performance, yield and quality attributes need to be understood. This study evaluates the effects of different irrigation schedulings on vine performance and grape composition in a vineyard of cv. ‘Sultani Çekirdeksiz’ (Sultana clone, H5) during three consecutive years (2015–2017). Three irrigation treatments were assayed: (i) full irrigation (FI), soil water content was completed to field capacity within one week intervals; (ii) DI65, applying 65% water of FI and (iii) DI35, applying 35% water of FI. Water stress caused by the deficit irrigation treatments limited vine performance in terms of vegetative development and yield. The highest phenolic content, antioxidant capacity and total flavonoid accumulation were obtained under DI35, although this treatment had lowest yield. In conclusion, DI65 (moderate stress) might result in a more balanced yield and grape quality attributes in comparison with FI and DI35.

In this study, biochemical and proteomic analyses were carried out on the ascocarp of Morchella tridentina Bres. For this, several ascocarp of M. tridentina were collected from different sites of Neelum Valley Azad Jammu and Kashmir, Pakistan. Identification was confirmed by phylogenetic sequencing using nuclear ribosomal DNA bar-coding technique along with morph-anatomical analysis. During the biochemical analysis, different bioactive compounds used in drugs to treat cancer, heart diseases, edema (veprisinium, visnagin, and bumetanide), and breast cancer (petunidin) were identified. Cerulinin, daidzein, guanthidin and okanin (imperative compounds) were also detected. Furthermore, protein analysis by FTICR/MS/Orbitrap revealed the presence of 921 proteins belonging to 171 protein groups having 165 unique peptide sequences. The study shows that this morel could be used as a source of bioactive substances to develop anticancer, antifungal, and antiviral drugs in the future. This fruitful addition of M. tridentina in Mycota of Pakistan increases the number of morels to three.

Investigation of the detailed pyrolysis characteristics of tobacco raw materials is important for the understanding of product design and consumption. In this work, pyrolysis characteristics and kinetic models of cigar filler tobacco (CFT), cigar wrapper tobacco (CWT), and flue-cured tobacco (FCT) were investigated by using a thermogravimetric analyzer coupled with Fourier-transform infrared spectroscopy (TG-FTIR). The pyrolysis of different tobacco samples could be divided into four stages based on the derivative thermogravimetric analysis (DTG) curves. Flue-cured tobacco underwent a marked decomposition process at lower temperatures (about 200 °C), while the thermal decomposition of cigar tobacco occurs at higher temperatures. During the pyrolysis process, evolved gases including H2O, CO2, CH4, CO, carbonyls, alcohols, phenols and aromatic compounds were detected by FTIR. CWT released more CO2 than CFT, while the amount of CO2, CH4, CO and aromatic compounds released by flue-cured tobacco was lower than that of cigar tobacco. The pyrolysis kinetics of tobacco leaves were further analyzed and compared through the isoconversional FWO (Flynn-Wall-Ozawa) and KAS (Kissinger-Akahira-Sunose) methods. The activation energy of FCT (from 100.1 kJ mol−1 to 192.1 kJ mol−1) was lower than that of CFT (from 207.36 kJ mol−1 to 319.28 kJ mol−1) and CWT (from 160.40 kJ mol−1 to 260.45 kJ mol−1). The thermal decomposition kinetics of different tobaccos were analyzed by Málek and Coats-Redfern methods.
Effects of lagging projectification in the public sector on realizing infrastructure projects
Authors: Wagner Reinhard F. , Radujkovic Mladen
Published: March 2022

The public sector in Germany lags behind the economy in terms of projectification, i.e., the prevalence of projects and experience in applying project management. This has significant implications for realizing complex infrastructure projects in which the public sector is involved as one of the main actors. Nowadays, projectification represents a particular way of thinking about how to embrace a series of dynamic and challenging changes, design them, and implement them effectively for the benefit of society. A quantitative study of projectification in society in Germany was the starting point for our research, the results of which we compared with data from earlier studies of projectification in the economy. Using an interpretative case study drawing on insights from the Berlin Airport, we analyzed the impact of lagging projectification in the public sector in Germany on realizing infrastructure projects to propose suitable approaches. The results of this case study reveal significant effects of lagging projectification in the public sector of Germany on realizing infrastructure projects. In the case of the Berlin BER Airport, an inadequate governance system led to a 9-year delay in the completion date and a 250% overrun of costs directly attributable to the project. This could have been avoided by involving the private construction industry more collaboratively, by building on previous experiences gained, and by a more cooperative way of project planning and implementation. To guide future research, hypotheses are derived that can be used to analyze the underlying problem in greater depth and to derive recommendations for action.
Balance of Cross-Functional Collaboration and Stretch and its Interaction with Firms’ Innovation Performance
Authors: Gerstberger Wolfgang
Published: March 2022

Literature does not provide a detailed explanation of the role of climate for innovation in the relationship between cross-functional collaboration and corporate innovation performance. The aim of this explorative study is therefore to investigate the complex interaction between cross-functional collaboration, climate for innovation and firms’ innovation performance. Based on the analysis of a random data sample of heads of works councils of 450 large-sized firms in Germany, working with innovation, this paper finds, that there is an effect between cross-functional collaboration and innovation performance which is complementary mediated by innovation climate. Overall, this finding leads to the conclusion that companies need to balance ‘soft’ factors as cross-functional collaboration and ‘hard’ factors as stretch in order to stimulate a productive innovation climate. Firms, which systematically work with and succeed in this balancing act, have also higher chances for increasing their innovation performance.
Cultural Diversity Drives Innovation: Does Institutional Residence Time Impact Behaviors?
Authors: Gallou Fabrice , Grandeury Arnaud , JONES GRAHAM
Published: March 2022

Innovation activities in large organizations are typically conducted by teams. Previous research noted the positive correlation between innovation performance and the cultural diversity of teams, wherein people from different backgrounds approach problems differently and have differing tolerances for risk. In a long term extension of these studies we aim to determine if these proclivities attenuate over time, as members modify & harmonize their behaviors driven by cultural norms of the organization. In an early read out from this effort, cohorts of innovation team members across several continents and representing six of the ten global cultural clusters completed a series of team analytics and questionnaires. The analytics were derived from cross-cultural communication frameworks which have been utilized to assess how culturally associated values influence behavioral traits. The respondents invited to participate were directly involved in innovation projects either as part of their main function or through membership of a specific innovation team and represented a range of experience levels. Subjects were also invited to offer written commentary on team and organizational culture as it applies to innovation. A definitive trend was uncovered wherein employee service time (in years) correlated with moves from cultural group norms towards more moderated, centrist decision making traits and lowered risk taking appetite. Further, specific indicators which correlate to disruptive ideation and innovation performance softened as a function of service time, independent of cultural origins. Together, this may signal a need for innovation teams to be mindful that balance is maintained with respect to members service time and new team entrants are supported to pursue high-risk high-reward ideas.
Choosing Between Innovative and Traditional Payment Systems: An Empirical Analysis of European Trends
Authors: Camilleri Silvio John , Agius Christabelle
Published: March 2022

The current variety of payment methods offers faster settlements and reasonable security, however payment innovations may be met with inertia or resistance.  This study addresses the characteristics which may be associated with the adoption of novel payment systems and salient user trends in this respect.  We investigate whether the reliance on traditional payment methods across European countries is related to socio-economic aspects, and also delve into the payment habits at the individual level.  Results from an econometric model suggest that financial market development and education-related factors are negatively related to the use of traditional payment instruments.  When considering consumer payment habits and awareness about novel facilities, particular differences across generations emerged.  Cash and debit cards are most widely used and it seems that such choices are related to perceived convenience rather than due to aversion towards novel systems.

Published: March 2022

We carried out a qualitative investigation of a pioneer of the Industrial Internet of Things operating in Silicon Valley since 1989. We reconstructed a sequence of strategic turns and conceptualized their current business model in a way that is relevant for several other industries enabled by the Internet, generalizing Thompson’s concept of mediating technologies in order to adapt it to contemporary, knowledge-based economies. We propose an interpretive framework for mediating technologies that we express by means of semantic networks.
The Impact of Emotional Experiences of Innovation Champions on Innovation Outcomes
Authors: Swart-Opperman Christina , Dharani Babar , April Kurt
Published: March 2022

This article aims to explore the impact of emotions and behaviours of innovation champions on organisation innovation outcomes. Our research suggests that champions do not necessarily contribute to successful outcomes. This could be ascribed to the fact that the role of the innovation champion is often oversimplified, while the context and specific emotional experiences of the champion impact champion behaviour. Therefore, for the purposes of this article, we considered the innovation champion as an internal role player, soliciting support for innovation and thereby influencing outcomes. The study reanalyses the interview data of twenty innovation champions from six African countries within the financial services industry. The article provides additional insights into the complexities associated with ‘championing’, linked to the champion’s own emotional experiences, discretionary and citizenship behaviours. The study reveals that, although there is an increased awareness of the factors triggering champion behaviours, the description of the fluid role of the champion remains a challenge. The role of the innovation champion and the question whether such roles are over- or underrated will thus continue to receive attention in literature.

Pseudo ST segment elevation myocardial infarction in a case of apical hypertrophic cardiomyopathy
Authors: Okonkwo Ekene Kenneth , Han Jennie , Attar Nadeem
Published: March 2022

Background:

Apical hypertrophic cardiomyopathy (AHCM) is a relatively rare variant of hypertrophic cardiomyopathy. The condition is associated with numerous clinical and electrocardiogram (ECG) features, some of which are well documented in the literature.

Case Presentation:

We present a case of a 77-year-old female who presented with a syncopal episode. Her ECG showed lateral ST segment elevation and her cardiac biomarkers were not in keeping with a myocardial infarction. She was diagnosed with AHCM based on characteristic findings on echocardiography. The association between AHCM and lateral ST segment elevation is one that has only been described in a handful of cases in literature.

Conclusion:

The authors hope that in presenting this case we can add to the body of literature and remind readers to be aware of the possibility that lateral ST segment elevation may be an indicator of AHCM, especially when this electrocardiographic feature occurs in the absence of the other well-known causes of ST segment elevation.
