Antecedents of Continuance Intention of Social Networking Services (SNS): Utilitarian, Hedonic, and Social Contexts

This study aims to identify the key factors that influence the continuance intentions of social network service (SNS) users through an integrative framework. It suggests a theoretical model that contains utilitarian, hedonic, and social contexts. Data were collected from 286 SNS users in South Korea. This study analyzed the data through partial least squares structural equation modeling (PLS-SEM). The results indicate that both perceived ease of use and perceived usefulness are not related to continuance intention. The findings show that perceived enjoyment has a strong and significant impact on continuance intention. The analysis results reveal that communication positively affects continuance intention. Moreover, system quality serves as the key factor of perceived ease of use, even though it has no significant effect on perceived usefulness. Information quality was found to have a significant impact on perceived usefulness but not on perceived ease of use. The results of the study intimated that service quality is significantly related to both perceived ease of use and perceived usefulness. Positive affect significantly affects both perceived enjoyment and communication. Negative affect significantly impacts perceived enjoyment while having no significant impact on communication. Theoretical contributions and practical implications are elaborated.
Evaluation of health screening data for factors associated with peri-implant bone loss

Purpose Systemic health has a profound effect on dental treatment. The aim of this study was to evaluate peri-implant bone loss and health screening data to discover factors that may influence peri-implant diseases. Methods This study analyzed the panoramic X-rays of patients undergoing health screenings at the Health Promotion Center at Seoul St. Mary’s Hospital in 2018, to investigate the relationship between laboratory test results and dental data. The patients’ physical data, such as height, weight, blood pressure, hematological and urine analysis data, smoking habits, number of remaining teeth, alveolar bone level, number of implants, and degree of bone loss around the implant, were analyzed for correlations. Their associations with glycated hemoglobin, glucose, blood urea nitrogen (BUN), creatinine, and severity of periodontitis were evaluated using univariate and multivariate regression analysis. Results In total, 2,264 patients opted in for dental health examinations, of whom 752 (33.2%) had undergone dental implant treatment. These 752 patients had a total of 2,658 implants, and 129 (17.1%) had 1 or more implants with peri-implant bone loss of 2 mm or more. The number of these implants was 204 (7%). Body mass index and smoking were not correlated with peri-implant bone loss. Stepwise multivariate regression analysis revealed that the severity of periodontal bone loss (moderate bone loss: odds ratio [OR], 3.154; 95% confidence interval [CI], 1.175–8.475 and severe bone loss: OR, 7.751; 95% CI, 3.003–20) and BUN (OR, 1.082; 95% CI, 1.027–1.141) showed statistically significant predictive value. The severity of periodontitis showed greater predictive value than the biochemical parameters of blood glucose, renal function, and liver function. Conclusions The results of this study showed that periodontal bone loss was a predictor of peri-implant bone loss, suggesting that periodontal disease should be controlled before dental treatment. Diligent maintenance care is recommended for patients with moderate to severe periodontal bone loss.
The prolonged effect of Kinesio Taping on joint torque and muscle activity

Abstract Purpose Although Kinesio Taping has been extensively used, evidence about the effect of Kinesio Taping is still insufficient. The aim is to determine the effect of Kinesio Taping on elbow joint torque and muscle activity in time and frequency domains. Materials and Methods Thirty-eight healthy subjects were (27 females and 11 males) randomly divided into control and Kinesio Taping groups. Kinesio Taping was applied over biceps brachii muscle in Kinesio Taping group, whereas no taping was applied to control group. Maximum elbow joint torque and electromyography activity in time and frequency domains were assessed during maximum isometric contraction of biceps brachii muscle at baseline, after 10 min, 30 min, and 24 h. Repeated measure ANOVA and mixed ANOVA tests were used for in-group and between-group comparisons, respectively. Results Elbow joint torques among four assessment sessions were statistically altered in Kinesio Taping group and greater in Kinesio Taping group than in control group (F(3,57)= 3.317, p = 0.026, ηp2 = 0.149; F(3,108)=3.325, p = 0.022, ηp2 = 0.085; respectively). No difference was found in time domain muscle activity among assessment sessions in each group and comparison of groups (p > 0.05). Low-gamma band activity was changed among assessment sessions in Kinesio Taping group (F(3,57)= 6.946, p < 0.001, ηp2 = 0.268) while group × time interaction was not determined. Conclusions Kinesio Taping may influence joint torque of elbow more than without Kinesio Taping condition in 24th hour but the interpretation of this effect as a muscle strength enhancement compared with baseline can be arguable. Even if Kinesio Taping could not affect muscle activity in time domain, low-gamma band activity which is closely related to somatosensorial input may reach highest magnitude 24 h after Kinesio Taping.
Analysis Towards the Factors Relates to the Yield at Sharia Bond Which Listed on Indonesia Stock Exchange During Period of 2020

This research analyzes the influence caused by the debt equity ratio (DER), maturity, firm size and rating of Islamic bonds on the yield to maturity (YTM) from corporate Islamic bonds. The research population consisted of corporate sharia bonds traded at the Indonesia Stock Exchange during period of 2020. The sample choosen technique was performed by purposive sampling. The research sample consisted of 59 corporate bonds that issued from 13 companies through all sectors except the banking and financial sectors. The research analysis method used descriptive statistics and multiple linear regression. The outcomes showed partially that the maturity variable had a significant positive affect to YTM, Rating had a negative affect on YTM, while DER and Islamic bond ratings had no affect on YTM. The research implication stated that companies need to increase their sharia bond ratings in order to maintain investor trust. For further research, it is expected to analyze other variables which had an impact to YTM because the coefficient of determination that reached from this research are 67%, while the remaining of 33% was determined by other variables which not explained in this research.
Estimation of the Minimum of a Function Using Order Statistics

Abstract Suppose A is a bounded set in ℛ d and f a real function defined on A. Suppose m = min{f(x; | x ∈ A} exists. Using a random sample X 1, X 2. …, X n from a uniform distribution over A we construct a confidence interval for m using asymptotic theory. Our results contain some statistical results valid in general extreme value theory (estimation of the main parameter of extreme value distributions).
Are Nonalcoholic Fatty Liver Disease and Bone Mineral Density Associated? — A Cross‐Sectional Study Using Liver Biopsy and Dual‐Energy X‐Ray Absorptiometry

There is controversy regarding the association between nonalcoholic fatty liver disease (NAFLD) and osteoporosis. Our study aim was to assess bone mineral density (BMD) in patients with biopsy‐proven NAFLD and examine if the severity of NAFLD affects BMD. A total of 147 adult women (n = 108) and men (n = 39) aged 18–76 years (mean ± standard deviation [SD] age 45.3 ± 12.5) were recruited in this cross‐sectional study and underwent a liver biopsy and dual‐energy X‐ray absorptiometry (DXA). NAFLD activity score (NAS) based on the degree of steatosis, lobular inflammation and hepatocellular ballooning was used to assess NAFLD severity. The majority of subjects, 53%, had steatosis, 25% had nonalcoholic steatohepatitis (NASH) whereas 23% served as control subjects with no evidence of NAFLD. There were no significant differences in the lumbar spine (1.09 ± 0.12, 1.11 ± 0.18, and 1.12 ± 0.15 g/cm2, p = 0.69, in controls, steatosis, and NASH, respectively) or hip BMD (1.10 ± 0.15, 1.12 ± 0.13, and 1.09 ± 0.13 g/cm2, p = 0.48, in controls, steatosis, and NASH, respectively) between the groups. Adjusting for age, gender, body mass index, and diabetes in multiple regression models did not alter the results. There was no correlation between NAS and neither lumbar spine BMD (r = 0.06, p = 0.471), nor hip BMD (r = −0.03, p = 0.716). In conclusion, BMD was similar across the spectrum of NAFLD in both genders and not related to the severity of the underlying histological lesions, suggesting that neither steatosis nor NASH exerts a detrimental effect on BMD in these relatively young patients. © 2022 The Authors.

Evidence for Elemental Variation in the Ejecta of the TYCHO Supernova Remnant

We present an X-ray study of the Tycho supernova remnant utilizing archival data from the high-resolution imagers (HRIs) on Einstein and ROSAT, the low-energy imaging telescopes (LEITs) on EXOSAT, and spectral data from the Broad Band X-ray Telescope (BBXRT). We have made use of the differing HRI bandpasses to construct images of Tycho in two spectral bands, o.7-1.8 keV and 1.8-4.5 keV. We find that the two images differ, with the harder image showing enhanced emission along much of the south, west, and north periphery. There appears to be enhanced soft emission in the interior and in one particular knot of emission in the southeast. Besides continuum (which we model here as thermal bremsstrahlung emission), we believe the hard image shows primarily the distribution of high-ionization Si and S K-shell lines which lie in the 1.8-2.6 keV band, while the softer image has contributions from Si as well as Fe XVII to Fe XXIV L-shell lines in the 0.7-1.4 keV band. Guided by the results of nonequilibrium ionization modeling of the BBXRT spectral data, we interpret the observed contrast in hard and soft X-ray emission in terms of variations in abundance, ionization timescale, and temperature. The most likely explanation for the spectral differences are spatial variations of the relative abundances of Si, S, and Fe.
Semiparametric Filtering of Spatial Autocorrelation: The Eigenvector Approach

In the context of spatial regression analysis, several methods can be used to control for the statistical effects of spatial dependencies among observations. Maximum likelihood or Bayesian approaches account for spatial dependencies in a parametric framework, whereas recent spatial filtering approaches focus on nonparametrically removing spatial autocorrelation. In this paper we propose a semiparametric spatial filtering approach that allows researchers to deal explicitly with (a) spatially lagged autoregressive models and (b) simultaneous autoregressive spatial models. As in one non-parametric spatial filtering approach, a specific subset of eigenvectors from a transformed spatial link matrix is used to capture dependencies among the disturbances of a spatial regression model. However, the optimal subset in the proposed filtering model is identified more intuitively by an objective function that minimizes spatial autocorrelation rather than maximizes a model fit. The proposed objective function has the advantage that it leads to a robust and smaller subset of selected eigenvectors. An application of the proposed eigenvector spatial filtering approach, which uses a cancer mortality dataset for the 508 US State Economic Areas, demonstrates its feasibility, flexibility, and simplicity.
Flux compactifications of Type II string theories under non-perturbative dualities

We consider string vacua formed by compactifying Type II string theories on toroidal orbifolds and generalised Calabi-Yau manifolds and their transformations under a set of non-perturbative dualities. The dualities are the Type IIA-IIB exchanging T duality, the self-symmetry of Type IIB S duality, the non-trivial combination of the two, U duality, and the generalisation of T duality to include Calabi-Yaus, mirror symmetry. The requirement of the effective theory superpotential being invariant under these dualities is used to justify additional fluxes which do not descend via compactification from the ten dimensional action, which form an N = 2 theory. Their non-geometric structures, Bianchi constraints and tadpoles are determined and then classified in terms of modular S duality induced multiplets. The Z2 Z2 orientifold is used as an explicit example of the general methods, with N = 1 Type IIB non-geometric vacua which possess T and S duality invariance also constructed. These are then used to motivate the existence of an exchange between moduli spaces on self mirror dual manifolds with N = 2. Such an exchange is seen to result in flux structures which are schematically the same as the standard formulation but with inequivalent flux constraints.
Energy-relaxation dynamics of photogenerated excitons observed from time-resolved photoluminescence of exciton-exciton scattering in CuI thin films

We have investigated the excitation-photon-energy dependence of time-resolved photoluminescence spectra of the P emission due to exciton-exciton scattering at $10\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ in CuI thin films from the viewpoint of energy-relaxation dynamics of photogenerated excitons. The ultrashort time resolution of $0.4\phantom{\rule{0.3em}{0ex}}\mathrm{ps}$ using an optical-Kerr-gating method enabled us to obtain precise information of the relaxation dynamics under various excitation-photon-energy conditions. It is found that the onset time of the P emission, which corresponds to the time required for the appearance of the P emission after the irradiation of an excitation pulse, increases with increasing excitation-photon energy, while the rise and decay times of the P emission are independent on the excitation-photon energy. These results indicate that the onset time is connected with an energy-relaxation time of the photogenerated excitons toward the bottleneck region of the exciton-polariton. On the basis of a Fr\"ohlich-interaction model, we have quantitatively analyzed the energy-relaxation time, taking account of interactions between the excitons and longitudinal optical (LO) phonons, the so-called cascade process of LO-phonon scattering, in momentum space.
De Novo Asp219Val Mutation in Cardiac Tropomyosin Associated with Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM), caused by mutations in thin filament proteins, manifests as moderate cardiac hypertrophy and is associated with sudden cardiac death (SCD). We identified a new de novo variant, c.656A>T (p.D219V), in the TPM1 gene encoding cardiac tropomyosin 1.1 (Tpm) in a young SCD victim with post-mortem-diagnosed HCM. We produced recombinant D219V Tpm1.1 and studied its structural and functional properties using various biochemical and biophysical methods. The D219V mutation did not affect the Tpm affinity for F-actin but increased the thermal stability of the Tpm molecule and Tpm-F-actin complex. The D219V mutation significantly increased the Ca2+ sensitivity of the sliding velocity of thin filaments over cardiac myosin in an in vitro motility assay and impaired the inhibition of the filament sliding at low Ca2+ concentration. The molecular dynamics (MD) simulation provided insight into a possible molecular mechanism of the effect of the mutation that is most likely a cause of the weakening of the Tpm interaction with actin in the "closed" state and so makes it an easier transition to the “open” state. The changes in the Ca2+ regulation of the actin-myosin interaction characteristic of genetic HCM suggest that the mutation is likely pathogenic.
Clinical Results According to Inferior Oblique Manipulation in Patients with Inferomedial Blowout Fracture Involving the Orbital Strut

Background Detachment of the inferior oblique muscle may be necessary under certain circumstances to repair a large inferomedial orbital fracture involving the orbital strut. This study aimed to evaluate the outcomes of patients who underwent surgeries with and without inferior oblique muscle reattachment after its detachment to repair the orbital wall fractures. Methods Forty patients who underwent repair of combined floor and medial orbital wall fracture involving the orbital strut at a single tertiary institution between January 2014 and December 2020 were reviewed. Groups 1 and 2 comprised 20 patients each, who underwent surgery with inferior oblique muscle detachment without and with reattachment, respectively, and were followed up for at least 6 months postoperatively. Enophthalmos, Goldmann diplopia test, alignment test, ocular motility test, and orbital inferomedial angle ratio were the outcome measures. Results Statistically significant improvement was observed in ocular motility, diplopia, and enophthalmos postoperatively at the 1- and 6-month follow-up (p < 0.01). The mean postoperative inferomedial angle ratio (102.28 ± 10.62%) was improved significantly compared with the preoperative inferomedial angle ratio (115.61 ± 4.38%) (p = 0.004) in all patients. After surgery, inferior oblique muscle underaction was observed in seven and six patients in groups 1 and 2, respectively, which was associated with preoperative extraocular movement limitation and strabismus. Two patients showed diplopia in both groups at the last follow-up; they had inferior oblique muscle underaction but no enophthalmos. Conclusion Orbital fracture repair with or without inferior oblique muscle reattachment was clinically effective and safe; however, patients with preoperative strabismus and extraocular motility limitation should be informed of the increased risk of postoperative complications.
A Questionnaire Survey on Hoa Sen University Students’ Positive and Negative Achievement Emotions in Learning

Achievement emotions are defined as emotions that are directly linked to achievement activities or achievement outcomes. Achievement emotions are very important in the learning process because they can affect learning performances and learning outcomes. This study was carried out with the intention of examining the types of emotions that students experience and the affective factors related to achievement emotions. In the current study, three positive emotions, including enjoyment, hope, and pride, and three negative ones, including anger, anxiety, and boredom, are examined using an adapted version of the Achievement Emotions Questionnaire by Pekrun (2002). Students' emotional experiences are studied in learning-related achievement situations at university. Three hundred eighty students currently attending Hoa Sen University participated in the study. The results reveal that the students have a moderate and high level of positive and negative emotions. In addition, there is a significant difference in students' level of positive achievement emotions in terms of gender, hometown, and major and negative emotions in terms of hometown. Moreover, in-depth interview results reveal that most of the problems which lead to negative emotions are related to individual students. From the results, some educational implications are drawn to help minimize learners’ negative emotions and foster their positive emotions.
Duality and modern economics

Dual arguments have become a standard tool for analysis of problems involving optimization by consumers and producers. The principal aim of this book is to provide a fairly systematic yet simple exposition of the basic structure of such arguments. The emphasis is not on providing mathematically general proofs; instead, a geometric approach is used to provide, in an informal way, an intuitive understanding of duality theory. This book introduces the most common alternative ways of representing preferences and technologies, such as indirect utility and distance functions, expenditure and cost functions, and profit and revenue functions. and it discusses the assumptions under which alternative formulations contain precisely the same information. Results such as Roy's identity. the Hotelling-Wold identity, and Shephard's lemma are fully explained. as are their roles in facilitating analysis of behaviour.
Consequences of the Covid‐19 pandemic on complex multimorbid elderly: Follow‐up of a community‐based cohort. SAMAC3 Study

Abstract Background The restrictions imposed during the management of the pandemic led to lack of care of other health problems. Purpose To assess changes in the health status of complex multimorbidity elderly, functional and cognitive capacities, perception of the social surroundings, care provided by the nurses, including nursing diagnosis and interventions, use of health services, adverse events, and use of devices and technical help during the first 6 months of the Covid‐19 pandemic. Design A 1‐year longitudinal cohort study was conducted. Methods Ninety‐seven complex multimorbid elderly attended in primary care were evaluated every 3 months in a health area of the Spanish National Health System (SNHS). The research was called “SAMAC3 study”. Results Significant negative changes were observed in the functional and cognitive capacity of the elderly, and in several nursing diagnoses. A decrease was observed in the frequency of visit to the nurses, hospital admittance, length of hospital stays, and falls. Conclusions The functional and cognitive capacities of the cohort became worse. However, a significant decrease in the frequency of use of health services was observed. The nurses detected significant changes in activity‐exercise, cognitive‐perception, and roles‐relationships, but their interventions were mostly centered on resolving clinical matters that required immediate attention. Clinical Relevance The present study allowed us to observe that a situation of social and health stress has worsened the health indicators of multimorbid elderly, and the clinical care of community nurses was insufficient to providing care for the deterioration of the physical and cognitive domains.
Minimally Invasive Live Tissue High-fidelity Thermophysical Modeling using Real-time Thermography

We present a novel thermodynamic parameter estimation framework for energy-based surgery on live tissue, with direct applications to tissue characterization during electrosurgery. This framework addresses the problem of estimating tissue-specific thermodynamics in real-time, which would enable accurate prediction of thermal damage impact to the tissue and damage-conscious planning of electrosurgical procedures. Our approach provides basic thermodynamic information such as thermal diffusivity, and also allows for obtaining the thermal relaxation time and a model of the heat source, yielding in real-time a controlled hyperbolic thermodynamics model. The latter accounts for the finite thermal propagation time necessary for modeling of the electrosurgical action, in which the probe motion speed often surpasses the speed of thermal propagation in the tissue operated on. Our approach relies solely on thermographer feedback and a knowledge of the power level and position of the electrosurgical pencil, imposing only very minor adjustments to normal electrosurgery to obtain a high-fidelity model of the tissue-probe interaction. Our method is minimally invasive and can be performed in situ. We apply our method first to simulated data based on porcine muscle tissue to verify its accuracy and then to in vivo liver tissue, and compare the results with those from the literature. This comparison shows that parameterizing the Maxwell–Cattaneo model through the framework proposed yields a noticeably higher fidelity real-time adaptable representation of the thermodynamic tissue response to the electrosurgical impact than currently available. A discussion on the differences between the live and the dead tissue thermodynamics is also provided.
