Innovative value propositions in the fashion metaverse

Russo Stefano Paolo,Mele Cristina,Spena Tiziana Russo 한국마케팅과학회 2024 Journal of Global Fashion Marketing Vol.15 No.1

At the present time, fashion companies experiment with the metaverse in pursuit of innovative value propositions (IVPs) to offer to customers, and this paper addresses that phenomenon. The metaverse is a “phygital” space that rests on a range of different technologies, leveraging the benefits they generate and enhancing their potential applications. We carried out an exploration of 17 cases across the fashion industry by deploying a “metaverse ethnography” to utilise thick data (qualitative information such as observations, feelings, and reactions) which offers contextual and qualitative insights. Our main contribution consists of a framework that has identified the metaverse as an enabler of IVPs. We address three main activities that fashion companies carry out to leverage the potential of the metaverse: crafting resources, designing contexts, and enabling experiences. Within these activities, fashion companies offer new value promises to customers and activate new strategic levers; both of these result in IVPs. We highlight implications for scholars, practitioners and for further research.

Importance of an Integrated Assessment of Functional Disability and Work Ability in Workers Affected by Low Back Pain

Russo Fabrizio,Di Tecco Cristina,Russo Simone,Petrucci Giorgia,Vadalà Gianluca,Denaro Vincenzo,Iavicoli Sergio 한국산업안전보건공단 산업안전보건연구원 2024 Safety and health at work Vol.15 No.1

Background This study examines the relationship between functional disability and work ability in workers affected by low back pain (LBP) through an analysis of correlations between the Oswestry Disability Index (ODI) and Work Ability Index (WAI). The role of personal and work factors on functional disability/work ability levels has also been studied. LBP is the most common musculoskeletal problem and a major disabling health problem worldwide. Its etiology is multifactorial. Multidisciplinary approaches may help reduce the burden of pain and disability and improve job continuity and reintegration at work. Methods A cohort of 264 patients affected by LBP from an Italian outpatient clinic were included in a clinical diagnostic/therapeutic trial aiming at rehabilitation and return to work through an integrated investigation protocol. Data were collected during the first medical examination using anamnestic and clinical tools. The final sample is composed of 252 patients, 57.1% man, 44.0 % blue collars, 46.4% with the high school degree, 45.6% married. Results WAI and ODI reported a negative and fair correlation (r = –0.454; p = .000). Workers with acute LBP symptoms have a higher probability of severe disability than those with chronic LBP symptoms. White collars without depressive symptoms reported higher work ability – even in chronic disability conditions-than those with depressive symptoms. Conclusion The study found that ODI and WAI have a convergent validity and this suggests that the two tools measure capture distinctive aspects of disability related to personal, environmental, and occupational characteristics. The most important and modifiable prognostic factors found for ODI and WAI were depressive symptoms, workday absence, and intensity of back pain. The study also found a mild association between age and ODI. The study's findings highlight the importance of using a multidisciplinary approach to manage and prevent disability due to LBP.

ON THE TOPOLOGY OF THE NONABELIAN TENSOR PRODUCT OF PROFINITE GROUPS

Russo, Francesco G. Korean Mathematical Society 2016 대한수학회보 Vol.53 No.3

The properties of the nonabelian tensor products are interesting in different contexts of algebraic topology and group theory. We prove two theorems, dealing with the nonabelian tensor products of projective limits of finite groups. The first describes their topology. Then we show a result of embedding in the second homology group of a pro-p-group, via the notion of complete exterior centralizer. We end with some open questions, originating from these two results.

Russo Luca,Avesani Giacomo,Gui Benedetta,Trombadori Charlotte Marguerite Lucille,Salutari Vanda,Perri Maria Teresa,Di Paola Valerio,Rodolfino Elena,Scambia Giovanni,Manfredi Riccardo 대한영상의학회 2021 Korean Journal of Radiology Vol.22 No.8

Immunotherapy is an effective treatment option for gynecological malignancies. Radiologists dealing with gynecological patients undergoing treatment with immune checkpoint inhibitors should be aware of unconventional immune-related imaging features for the evaluation of tumor response and immune-related adverse events. In this paper, immune checkpoint inhibitors used for gynecological malignancies and their mechanisms of action are briefly presented. In the second part, patterns of pseudoprogression are illustrated, and different forms of immune-related adverse events are discussed.

ON GROUPS SATISFYING THE MAXIMAL AND THE MINIMAL CONDITIONS FOR SUBNORMAL SUBGROUPS OF INFINITE ORDER OR INDEX

Russo, Alessio Korean Mathematical Society 2010 대한수학회보 Vol.47 No.4

In this article we will prove that a generalized radical group satisfying the maximal condition for subnormal subgroups of infinite order (the minimal condition for subnormal subgroups of infinite index, respectively) is soluble-by-finite. Such result generalizes that obtained by D. H. Paek in [5].

Marina Russo,Caterina Strisciuglio,Elena Scarpato,Dario Bruzzese,Marianna Casertano,Annamaria Staiano 대한소화기 기능성질환∙운동학회 2019 Journal of Neurogastroenterology and Motility (JNM Vol.25 No.1

Background/Aims Functional constipation (FC) is aa frequent functional gastrointestinal disorder, diagnosed according to the Rome criteria. In this study, we compared Rome III and Rome IV criteria for the diagnosis of FC, and determined the prevalence of FC according to these criteria. Methods Consecutive children between infancy and 17 years old were recruited for the study, excluding those with a known organic gastrointestinal disease. A prospective longitudinal design has beenused. For the diagnosis of FC, questionnaires on Pediatric Gastrointestinal Symptoms (QPGS) based on the Rome III and Rome IV criteria (QPGS-RIII and QPGS-RIV) were used. The agreement between these 2 questionnaires was measured by Cohen’s kappa coefficient. Results Two hundred fourteen children (mean age, 77.4 ± 59.5 months; 103 males) were screened. There was no statistically significant difference in the prevalence of FC evaluated using the QPGS-Rome IV vs the QPGS-Rome III in the overall sample (39/214 [18.2%] vs 37/214 [17.3.0%]; P = 0.831) as well as in any of the groups. The Cohen’s kappa test showed a good agreement between the 2 criteria (κ = 0.65; 95% CI, 0.51 to 0.78). Conclusion Our study demonstrates that the new Rome IV criteria have a good agreement with the Rome III criteria for the diagnosis of FC, without an increase in the number of potential diagnoses, despite the reduction in the duration of the symptoms. This conclusion is important in the management of childhood FC, since a late diagnosis negatively affects the prognosis.

On the convergence of a semi-Lagrangian scheme for the BGK model of the Boltzmann equation

Giovanni Russo,Piero Santagati,Seok-Bae Yun 한국산업응용수학회 2009 한국산업응용수학회 학술대회 논문집 Vol.2009 No.5

Recently, the first and second authors proposed a semi-Lagrangian scheme for the BGK model of the Boltzmann equation. In this talk, we show that the approximate distribution function of the scheme converges to the smooth solution of the BGK model. We also derive an explicit convergence estimate.

Morinda citrifolia Linn Leaf Extract Possesses Antioxidant Activities and Reduces Nociceptive Behavior and Leukocyte Migration

Mairim Russo Serafini,Rodrigo Correia Santos,Adriana Gibara Guimarães,João Paulo Almeida dos Santos,Alan Diego da Conceicão Santos,Izabel Almeida Alves,Daniel Pens Gelain,Paulo Cesar de Lima Nogueira 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.10

Herbal drugs have been used since ancient times to treat a wide range of diseases. Morinda citrifolia Linn (popularly known as “Noni”) has been used in folk medicine by Polynesians for over 2,000 years. It is reported to have a broad range of therapeutic effects, including effects against headache, fever, arthritis, gingivitis, respiratory disorders, infections, tuberculosis, and diabetes. The aim of this study was to investigate the antioxidant, anti-inflammatory, antinociceptive, and antibacterial properties of the aqueous extract from M. citrifolia leaves (AEMC). Antioxidant activity was observed against lipid peroxidation, nitric oxide, and hydroxyl radicals. The antinociceptive effect of AEMC was observed in the acetic acid–induced writhing test at the higher dose. Moreover, AEMC significantly reduced the leukocyte migration in doses of 200 and 400 mg/kg and showed mild antibacterial activity. Together, the results suggest that properties of M. citrifolia leaf extract should be explored further in order to achieve newer tools for managing painful and inflammation conditions, including those related to oxidant states.
