Gender inequality among champions and players’ reception of gender disproportion of utility support champions in league of legends

Designing female character in video game has been criticized as being sexually objectified and underrepresented in quantity (number of characters and their appearance rate in the game) and in quality (take only secondary role and inferior ability statistics given). In this paper, we analyze world leading multiple-user online battle arena game league of legends to see if previously criticized gender inequality of champions still stands and conduct a survey of 1,403 players of that game and asks how they feel about serious gender disproportion of utility support champions (all females). The result shows that league of legends still has serious gender disparity in performance parameters and there has been only a small change in 5-year span (2014-2019). The survey result tells us that game players also feel political incorrectness of such gender disproportion, but they accept such gender prototype because they have been taught as such as social role theory explains gender inequality issues

Effects of thermal boundary conditions on natural convection in a square enclosure with an inner circular cylinder differdentially heated from bottom wall

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.Two-dimensional numerical simulations are carried out for natural convection in an enclosure with a hot inner cylinder located at the center for four different Rayleigh numbers of 103, 104, 105 and 106. The immersed boundary method (IBM) was used to handle the virtual surface of the inner circular cylinder with a no-slip boundary condition. The Prandtl number Pr was taken to be 0.7 corresponding to that of air. This study focuses on the effect of the temperature variation of bottom wall of the enclosure on thermal and flow structures of natural convection. The results indicate negligible changes in thermal and flow structures based on variations in the size of the local heating zone on the bottom wall at Ra =103 and 104, although there is a small variation in the convection velocity in the enclosure. At Ra = 105, small inner vortices formed in the lower part of the cylinder show significant changes in their size with increases due to increasing the bottom wall temperature. At Ra = 106, the magnitude of convection velocity becomes much larger than that when Ra = 105. As a result, much stronger rising plumes than those for Ra = 105 were formed on the top of the cylinder. And the secondary vortices form and separate above the bottom surface of the cylinder. The generation and dissolution of vortices are dependent mainly on the temperature of bottom wall in the enclosure.dc201

Changes in Fire Weather Climatology Under 1.5 ◦C and 2.0 ◦C Warming

The 2015 Paris Agreement led to a number of studies that assessed the impact of the 1.5 ◦C and 2.0 ◦C increases in global temperature over preindustrial levels. However, those assessments have not actively investigated the impact of these levels of warming on fire weather. In view of a recent series of high-profile wildfire events worldwide, we access fire weather sensitivity based on a set of multi-model large ensemble climate simulations for these low-emission scenarios. The results indicate that the half degree difference between these two thresholds may lead to a significantly increased hazard of wildfire in certain parts of the world, particularly the Amazon, African savanna and Mediterranean. Although further experiments focused on human land use are needed to depict future fire activity, considering that rising temperatures are the most influential factor in augmenting the danger of fire weather, limiting global warming to 1.5 ◦C would alleviate some risk in these parts of the world

Nasal Deformity Due to Tuberculous Chondritis

Tuberculosis (TB) is a common disease worldwide. However, nasal TB is quite rare, and the diagnosis of nasal TB requires a high index of suspicion. The most common symptoms of this unusual presentation are nasal obstruction and nasal discharge. We present a case of nasal TB with involvement of the hard palate presenting with a chronically progressive nasal deformity and ulceration of the hard palate. A biopsy confirmed the diagnosis, and medication for TB was started and the lesions resolved. When a patient presents with chronic ulcerative lesions that do not respond to antibiotic treatment, TB should be included in the differential diagnosis. Biopsy of the lesion can aid in the confirmation of the diagnosis

Association between baseline smoking status and clinical outcomes following myocardial infarction

BackgroundWhether the effect of smoking on clinical outcomes following an acute myocardial infarction (AMI) is beneficial or detrimental remains inconclusive. We invesetigated the effect of smoking on the clinical outcomes in patients following an AMI.MethodsAmong 13,104 patients between November 2011 and June 2015 from a nationwide Korean AMI registry, a total of 10,193 participants were extracted then classified into two groups according to their smoking habit: (1) smoking group (n = 6,261) and (2) non-smoking group (n = 3,932). The participants who smoked were further subclassified according to their smoking intensity quantified by pack years (PYs): (1) <20 PYs (n = 1,695); (2) 20–40 PYs (n = 3,018); and (3) ≥40 PYs (n = 2,048). Each group was compared to each other according to treatment outcomes. The primary outcome was the incidence of major adverse cardiac and cerebrovascular events (MACCEs), which is a composite of all-cause mortality, non-fatal MI (NFMI), any revascularization, cerebrovascular accident, rehospitalization, and stent thrombosis. Secondary outcomes included the individual components of MACCEs. The Cox proportional hazard regression method was used to evaluate associations between baseline smoking and clinical outcomes following an AMI. Two propensity score weighting methods were performed to adjust for confounders, including propensity score matching and inverse probability of treatment weighting.ResultsWhile the incidence of all clinical outcomes, except for stent thrombosis, was lower in the smoking group than in the non-smoking group in the unadjusted data, the covariates-adjusted data showed statistical attenuation of these differences but a higher all-cause mortality in the smoking group. For smokers, the incidence of MACCEs, all-cause mortality, cardiac and non-cardiac death, and rehospitalization was significantly different between the groups, with the highest rates of MACCE, all-cause mortality, non-cardiac death, and rehospitalization in the group with the highest smoking intensity. These differences were statistically attenuated in the covariates-adjusted data, except for MACCEs, all-cause mortality, and non-cardiac death, which had the highest incidence in the group with ≥40 PYs.ConclusionSmoking had no beneficial effect on the clinical outcomes following an AMI. Moreover, for those who smoked, clinical outcomes tended to deteriorate as smoking intensity increased

A novel polymer-free everolimus-eluting stent with a nitrogen-doped titanium dioxide film inhibits restenosis and thrombosis in a swine coronary model

Background: Short-term outcomes regarding the safety and efficacy of a polymer-free everolimus-eluting stent (EES) with a nitrogen-doped titanium dioxide (N-TiO2) film in a swine coronary model have been reported. However, the long-term results of the use of this type of stent have not yet been evaluated or compared to those of other polymer-free coronary stents. Therefore, this study aimed to determine the mid- to long-term safety and efficacy of a polymer-free EES with an N-TiO2 film in a swine coronary model. Methods: Polymer-free EES with N-TiO2 films (n = 30) and polymer-free sirolimus-eluting stents (SES; n = 30) were implanted in 30 pigs. Quantitative coronary analysis and optical coherence tomography were conducted immediately and at 1 (quantitative coronary analysis only), 3, and 6 months after stenting. Histopathologic examinations were performed at 1, 3, and 6 months after stenting. Results: The polymer-free EES group had a lower percentage of neointimal growth than the polymer-free SES group at 3 months (22.5% ± 11.4% vs. 32.1% ± 12.3%; p < 0.001). The polymer-free EES group had a lower fibrin score than the polymer-free SES group at 1 month (1.9 ± 0.45 vs. 2.5 ± 0.54; p = 0.001). The re-endothelialization rates were similar between groups. The polymer-free EES group had a lower percentage of the area of stenosis than the polymer-free SES group throughout the follow-up period. Conclusions: The novel polymer-free EES with an N-TiO2 film has superior safety and efficacy than the polymer-free SES at the 6-month follow-up in a swine model
