This paper focuses on a method to train a regression model from incomplete input values. It is assumed in this paper that there are no missing values in a training dataset while missing values exist during a prediction phase using the trained model. Under this assumption, we propose Intentional-Value-Substitution (IVS) training to obtain a machine learning model that makes the prediction error as minimum as possible. In IVS training, a model is trained to approximate the target function using a modified training dataset in which some feature values are substituted with a certain value even though their values are not missing. It is shown through a series of computational experiments that the substitution values calculated from a mathematical analysis help the models correctly predict outputs for inputs with missing values.

This study presents a repetitive control method based on a multi-stage particle swarm optimization (PSO) algorithm with variable intervals to enhance the tracking performance of Takagi–Sugeno (T–S) fuzzy systems. First, a T–S fuzzy model is used to describe a nonlinear system. A modified repetitive control structure with two repetitive loops guarantees the tracking accuracy of periodic signals. Taking advantage of the two-dimensional (2D) property with continuous control and discrete learning, a continuous-discrete 2D model is presented to describe the nonlinear repetitive control system. Next, a multi-stage PSO algorithm with variable intervals searches for the best parameter combination in the linear matrix inequality-based stability condition to regulate the control and learning actions, which avoids a suboptimal solution and guarantees high control accuracy. Finally, an application to control the speed of synchronous motor with a permanent magnet demonstrates the validity of the method, and comparisons with related methods show its superiority.

Cloud storage technology has attracted a considerable number of users owing to its exponential growth. Storing data in the cloud can save the resources of local storage configuration and reduce the cost of local hardware investment. However, the data stored in the cloud is out of the physical control (out of control) of the user. Based on the service characteristics of the cloud environment and the security requirements of user privacy data in the cloud environment, this paper proposes an improved identity proxy re-encryption algorithm based on the advanced encryption standard algorithm. The performance of the algorithm is optimized by reducing the number of bilinear mapping operations, whose calculation takes the longest time in the proxy re-encryption scheme. Only two bilinear mapping operations are required in this scheme. In addition, the encrypted data are tested to different degrees. The experimental results show that this scheme satisfies encryption and decryption performance requirements of the user.

Captions, which are used as a means of information support for deaf and hard-of-hearing students, are usually presented only in text form. Therefore, when mathematical equations and figures are frequently used in a classroom, the captions will show several demonstrative words such as “this equation” or “that figure.” As there is a delay between the teacher’s utterance and the display of the captions sometimes, it is difficult for users to grasp the target of these demonstrative words accurately. In this study, we prepared hybrid captions with mathematical equations and figures and verified their effectiveness via a comparison with conventional text-only captions. The results suggested that the hybrid captions were at least as effective as the conventional captions at helping the students understand the lesson contents. A subjective evaluation with a questionnaire survey also showed that the experimental participants found the hybrid captions to be acceptable without any discomfort. Furthermore, there was no difference in the number of eye movements of the participants during the experiment, suggesting that the physical load was similar for both types of captions.

Although sunlight is a promising renewable energy source, the light is incoherent and difficult to use directly. Therefore, a solar-pumped laser, which directly converts sunlight into coherent laser light of, is a promising technology. A solar-pumped laser collects sunlight into the laser medium to realize laser oscillation. In order to realize an efficient solar-pumped laser system, it is necessary to design a pumping cavity that absorbs maximal sunlight into the laser medium with minimal thermal shock. In this research, the pumping cavity shape was studied using a numerical ray tracing simulation. As a result, it was found that a cone shaped pumping cavity can be expected to improve the absorption rate by approximately 30% over a cylindrically shaped pumping cavity. Furthermore, the absorption power density distribution can be flattened by a vase shaped pumping cavity, while maintaining the same absorption efficiency. The vase shaped pumping cavity has almost half the dispersion of the absorbed power density in the laser medium when compared with the cone shaped pumping cavity.

In recent years, there have been several breakthroughs in the theoretical research of servo control algorithms. However most of these control algorithms remain in the simulation stage. They are difficult to be applied directly to practical platforms or complex industrial sites because of the lack of an experimental system suitable for the verification of their effectiveness. To address this problem, we designed a multi-function servo control algorithm verification experiment system (MVES) within the MATLAB/Simulink theoretical simulation model directly to communicate with the TwinCAT 3 PLC master program to perform different servo control experiments. The MVES supports various Simulink models. However, its and the operation is simple and convenient, which greatly reduces the workload of the algorithm test and has important practical value. Two sets of comparative experiments were used to verify the versatility and superiority of MVES.

Background: There is no information on human and animal Cryptosporidium spp. in Njoro sub- county. The risk posed to humans and animals within the sub-county is therefore unknown. Materials and Methods: A total of 1476 animal and 378 human fecal samples were evaluated. Multivariate logistic regression was used to evaluate association between infection status and the predisposing factors. Results were expressed as odds ratio (OR) with a 95% confidence interval. Chi-square and Maentel–Haenszel tests were used to quantify relationships among variables. Results: Prevalence of Cryptosporidium spp. was 9.8% in humans, 10.8% in cows, 19.6% in sheep and 4.5% in goats. Prevalence in humans was significantly higher in females 12/37. Infection was highest in the elderly (27.27%), and significantly lower in adolescents and adults at 8.66% and 9.59%, respectively. Goats had lowest overall parasitization at all levels, while sheep had the highest parasitization at levels (+1 and +2). Relatively, humans had the highest parasite counts +3 cases (1.5%). Conclusion: Cryptosporidium spp. is prevalent in Njoro sub-county and domestic animals are important reservoirs and a potential source of zoonosis in humans. Children, elderly and females are at increased risk of infection, especially during rainy season. The study recommends maintenance of proper sanitation when handling domestic animals, treatment of drinking water and use of alternative safer sources of water in order to reduce infection.

Background: Leprosy is a disease that causes social, psychological, and economic issues. Failure to treat the causes of the immune system dysregulation in endemic areas of leprosy conditions makes the transmission of the bacteria easier. This paper aims to analyze the comparison of family income, occupation types of mothers and fathers, number of children, access to health facilities, and education of mothers, fathers, and children in mothers and children with leprosy in endemic and non-endemic areas. Materials and Methods: A cross sectional study by survey was done in both an endemic and a non-endemic area of leprosy in Tuban Regency, East Java, Indonesia. Retrieval of research data was done using interview techniques. Respondents who participated in this study were 106 pairs of mother and child respondents who met the research restriction criteria. Subjects were divided into 5groups based on diagnosis of leprosy and area of living. Bivariate analysis was performed by comparing the independent variables in each group A, B, C, and D with group E. Results:It was found that the variables that differed significantly between the endemic and non-endemic areas were the variable number of children with a p-value=0.004, family income with a p-value=0.049 and the variable mother’s education with a p-value=0.016. Meanwhile, other variables do not have significant difference. Conclusions:We found significant difference on the number of children, father’s education, mother's education, and family income. These variables can be a risk factor for leprosy. To make efforts to prevent the transmission of leprosy, stakeholders should consider these factors.

Significance. Strengthening providers integration to improve health indicators is an important direction of healthcare development. Purpose. To evaluate the degree of providers interaction and continuity of health care. Material and methods. Forms of interaction between health services, medical organizations and social services have been determined, its prevalence is considered as a characteristic of the level of interaction. The sociological survey of physicians was conducted in October 2020 to identify their opinion about the interaction forms. The responses were compared with the results of a similar survey in 2012. Results. Comparison of the 2012 survey and 2020 survey suggests some improvements in interaction between district physicians and outpatient specialists, however its level is hardly adequate. Interaction between district physicians and emergency care providers in polyclinics has improved. Interaction between polyclinic and hospital physicians before and after hospital admission is very limited and has deteriorated over the period under study. The level of outpatient physicians’ awareness of emergency calls and hospital admissions of their patients is low. Interaction between polyclinics and hospitals on the one hand, and rehabilitation units and social care providers on the other hand, is also low. Information on the location and volumes of care provided to patients is still inaccessible for most physicians. This limits continuity of care. Conclusion. The study shows that the Russian healthcare system remains fragmental. This is the result of low priority of integrative activities, as well as low involvement of health managers in these activities. Scope of application. The need for specifying activities aimed at improving health providers integration as a special subject of health policy has been substantiated. The results can be used by health policy decision-makers, health managers and health professionals.

Diseases of the ear and mastoid process in children are frequent causes of acute conditions and can lead to hearing loss - conductive and sensorineural hearing loss. Even one-sided hearing loss in children can lead to impaired speech development, cause psychoemotional disorders and become a serious barrier to education. The purpose of the study was to analyze dynamics in incidence of diseases of the ear and mastoid process in children in the Krasnoyarsk Krai, Central Siberia. Material and Methods. The authors have analyzed official data on incidence of diseases of the ear and mastoid process as well as other diseases of this class among children aged 0-14 from 2009 to 2018 in the Krasnoyarsk Krai. Results. The study shows that incidence of diseases of the ear and mastoid process in children aged 0-14 exceeds similar indicators in the Russian Federation and the Siberian Federal district. At the same time, despite the decreased prevalence and overall incidence of diseases of the ear and mastoid process during the study period there was a significant increase in the incidence of conductive and sensorineural hearing loss. Furthermore, a positive statistically significant association between the number of otorhinolaryngologists and the incidence of conductive and sensorineural hearing loss has been identified. Conclusion. In the Krasnoyarsk Krai, there is a significant number of undiagnosed cases of conductive and sensorineural hearing loss associated with low number of otorhinolaryngologists. Low share of the detected cases of diseases of the ear and mastoid process during regular check-ups suggests their low effectiveness. The study findings necessitate an in-depth analysis of the effectiveness of regular medical check-ups in the region with a low number of specialty doctors. Scope of application. The study results can be used in planning medical resources for pediatric population to ensure early detection and early initiation of treatment of conductive and sensorineural hearing loss.

Significance. Population aging is considered one of the characteristic features of the modern demographic processes. This is both a forecast for the future and a basis for setting goals for health systems. Thus, the 2008 analytical review of the WHO Regional Office for Europe says that the long-established type of the fragmented care needs to be replaced by a comprehensive and coordinated type of care [1]. It is logical that this phenomenon affects not only health care, but goals of the social services as well, and economic indicators in general. In this regard, many countries have been undertaking efforts to implement or improve long-term care. Purpose. To evaluate medical and social care organization for the elderly and senile population in the world on the basis of the content analysis. Material and methods. Content analysis of the World Health Organization documents on medical and social care organization for the elderly and senile population. A total of 212 documents have been analyzed, 54 out of them have been selected for the analysis including 38 WHO materials and 16 scientific publications on the topic. Selection criteria - the documents should contain sufficient information on medical and social care organization for the elderly and senile population. Results. Analysis of the selected documents and publications has identified an urgent need to develop a comprehensive system of medical and social care delivery for the elderly as a separate group of the population with its peculiar characteristics of the course of diseases, comorbidity, and the need for long-term care.
Evolution of the YouTube Personas Related to Survival Horror Games
Authors: Toniolo Francesco
Published: March 2021

The indie survival horror game genre has given rise to some of the most famous game streamers on YouTube, especially titles like Amnesia: The Dark Descent (Frictional Games 2010), Slender: The Eight Pages (Parsec Productions 2012), and Five Nights at Freddy’s (Scott Cawthon 2014). The games are strongly focused on horror tropes including jump scares and defenceless protagonists, which lend them to displays of overemphasised emotional reactions by YouTubers, who use them to build their online personas in a certain way. This paper retraces the evolution of the relationship between horror games and YouTube personas, with attention to in-game characters and gameplay mechanics on the one hand and the practices of prominent YouTube personas on the other. It will show how the horror game genre and related media, including “Let’s play” videos, animated fanvids, and “creepypasta” stories have influenced prominent YouTuber personas and resulted in some changes in the common processes of persona formation on the platform.
Coconuts, Custom-Play & COVID-19: Social Isolation, Serious Leisure and Personas in Animal Crossing: New Horizons
Authors: Comerford Chris
Published: March 2021

This paper discusses Animal Crossing: New Horizons’ (ACNH) release during the COVID-19 pandemic, and draws upon responses from nearly 2000 players to frame how the game acts as a platform for routine substitution and social connectivity in a disconnected physical world. A combination of the game’s elements, including its comforting aesthetic, participatory community, financial mechanics, and goal-setting, promotes the player’s construction of their sense of self and provides crucial stability. In contrast to other life simulator games such as The Sims, the timing of ACNH’s release makes its substitution efforts more adoptable by a wide spectrum of players between casual and hardcore sensibilities.
Moreover, the game substitutes some complex face-to-face interactions during self-isolation and it affords stability and routine through a simulacrum of real-life, however exaggerated and narrowed in scope. The gameplay provides player agency and self-determination of playstyle as well as routines that contrast with the intense disruption of the everyday by the pandemic. Players’ shared affinities and engagement with the game function as a form of serious leisure which in turn creates personas from a diverse range of roles such as, the social player, the turnip trader, the gardener, the artisan. The persona roles enable players to adopt multiple recognisable specialisations within an expansive social environment. In essence, players of ACNH create an array of malleable, interchangeable gaming personas that successfully embody the routine and social play forcibly absent from real life during the pandemic.

La Escuela de Aviación del Ejército Nacional de Colombia desarrolla desde hace un tiempo proyectos de innovación en tecnología sin modelos de gestión que respondan a las características de los productos y las necesidades de la industria aeronáutica. Por esta razón, se presenta un modelo para el desarrollo de proyectos de innovación en tecnología dirigido a este campo, integrando buenas prácticas de gestión de proyectos desde el análisis y el desarrollo de productos, modelos y estándares internacionales de la ingeniería para su aplicación en futuros proyectos. El modelo construido se aplicó al diseño de un banco de pruebas digital para las pruebas caza fallas de la GCU —Generator Control Unit— de las aeronaves Beechcraft King, en las que se analizó su aplicación en cada una de las fases del desarrollo del proyecto y el resultado final respecto a tiempos, costos y alcance. Como resultado fue posible determinar que el modelo contribuyó a la correcta gestión en cada fase del proyecto y aseguró un cumplimiento adecuado del tiempo y los procedimientos técnicos y de calidad, en comparación con otro proyecto ejecutado sin el uso del modelo. La evaluación del modelo permitió verificar también la innovación del producto que para este caso fue de enfoque estructural, por lo que se puede considerar como modelo integrado IIP — Integrate, Innovation, Process—, lo que permite la generación de nuevo conocimiento y de nuevos modelos de negocio en fases posteriores de maduración y futura comercialización.

The WHO has defined the obstruction of the availability, access, and delivery of therapeutic and/or preventive health services as a form of health attack. The Palestinian Authority faces significant challenges to ensure the sustainability of the delivery of its health services systems. The blockade of the Gaza Strip and the presence of Israeli settlements in oPt and the Separation Wall around Jerusalem all these obstacles affect the patient’s right to access health care services. Palestinian Patients need permit applications from Israeli authorities that require usually 7- 10 days depending on the case condition and the appointment from the target hospital in which the permit may be approved or denied or delayed. It has become a complex process due to the need to cross barriers or border crossings and restrictions on the movement of Palestinian patients and ambulances imposed by the Israeli government. Therefore, barriers policy to accessing health care services are a serious and permanent condition that can lead to a very stressful atmosphere and result in developing mental problems. This paper aims to provide an overview of the literature and established studies on mental health consequences related to access limitations policy to health care services system in Palestine.Method: PubMedand Google Scholar were used to search for materials for the literature review study. The Data in this literature review wascollected by searching in electronic databases such as PubMed and Google Scholar. The keywords used in the searching process are Mental Health AND consequences AND limited access OR Access Limitations AND health care services OR health care AND barrier AND Gaza strip OR West Bank AND Palestine. full-text articles critically appraised were included while the duplicated papers were extracted.The papers in this review follow the IMRAD style (Introduction, method, results, and discussion section).Result: More than 25 related materials founded including review studies, 3 WHO reports, and 2 Palestinian government statistical reports.Conclusion:Evidences from this review show that there is a necessity to maintain justice and equality among the Palestinian population and their right to freedom. Limited access to health-care services for Palestinian patients living in Gaza Strip, West Bank ,andEast Jerusalem affect negatively the patient’s quality of life and mental health mainly due to the Israeli Separation Wall besides road closures.

Background and aims: Cholesterol crystals have been proved to be able to cause inflammation. NLRP3 inflammasome is activated in response to the accumulation of cholesterol crystals to produce IL-1β, which is associated with atherosclerotic lesions. NLRP3, as part of innate immunity, is involved in the regulation of inflammatory activity described above. The main objective of this study was to investigate the relationship between the polymorphism of NLRP3 rs10754558 and the susceptibility to arteriosclerosis obliterans (ASO) in Chinese Han males. Methods: The NLRP3 rs10754558 genotype was detected by the TaqMan allele assays in 758 male patients suffered from arteriosclerosis obliteration and 793 male controls. Blood glucose, total cholesterol (TC), triglyceride (TG), urea nitrogen, creatinine, serum uric acid, high-density lipoprotein, low-density lipoprotein, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and IL-1β were detected in all subjects. Clinical data were recorded and genotype-phenotype was analyzed. Independent sample T test was used for comparison between the two groups. The odds ratio (ORs) with 95% confidence interval (CIs) was calculated to show the strength of the relationship between the genotype distribution or allele frequencies and ASO. Genotype-phenotype analysis was performed in ASO patients by ANOVA. Results: The frequencies of genotype and allele in ASO group were significantly different from that in control group (p = 0.022 by genotype, p = 0.003 by allele). People who were carrying genotype GG had a higher risk for ASO than those carrying genotype CC (OR=1.574,95％CI 1.161-2.135,P=0.003) ,which was still significant after the adjustment of the history of smoking, TC, LDL, fasting blood glucose, systolic blood pressure and BMI(OR=1.448,95％CI 1.046-1.461,P=0.004). Moreover, there was an interaction between rs10754558 of NLRP3 and rs2043211 of CARD8 gene. Under the premise of carrying the T allele of CARD8 rs2043211, the G allele of NLRP3 rs10754558 increases the susceptibility to ASO. This gene-gene interaction is consistent with IL-1β levels. Conclusion: Our finding suggests the polymorphisms of NLRP3 rs10754558 are probably associated with the development of ASO in Chinese Han male population. And there may be an interaction between rs10754558 of NLRP3 and rs2043211 of CARD8 gene in the development of ASO.

Purpose: To evaluate the diagnostic accuracy of a commercially available test kit for noninvasive prenatal determination of the fetal RhD status (NIPT-RhD) with a focus on early gestation and multiple pregnancies. Methods: The FetoGnost RhD assay (Ingenetix, Vienna, Austria) is routinely applied for clinical decision making either in woman with anti-D alloimmunization or in order to target the application of routine antenatal anti-D prophylaxis (RAADP) to women with a RhD positive fetus. Based on existing data in the laboratory information system the newborn’s serological RhD status was compared with NIPT RhD results. Results: Since 2009 NIPT RhD was performed in 2,968 pregnant women between week 5+6 and 40+0 of gestation (median 12+6) and conclusive results were obtained in 2,888 (97.30%) cases. Diagnostic accuracy was calculated from those 2244 (77.70%) cases with the newborn’s serological RhD status reported. The sensitivity of the FetoGnost RhD assay was 99.93% (95% CI 99.61% - 99.99%) and the specificity was 99.61% (95% CI 98.86% - 99.87%). No false positive or false negative NIPT RhD result was observed in 203 multiple pregnancies. Conclusion: NIPT RhD results are reliable when obtained with FetoGnost RhD assay. Targeted routine anti-D-prophylaxis can start as early as 11+0 weeks of gestation in singleton and multiple pregnancies.

Background: Patients with intestinal obstruction consist of a major proportion of emergency room visits and the complication is associated with significant morbidity and mortality. It has a diverse etiology and varies from region to country. In developed countries it is mainly due to adhesions and in developing countries due to obstructed hernias. Although there are numerous studies from the western world there have been few recent publications from the developing world. Method: We retrospectively analyzed all the patients admitted for intestinal obstruction to our department from January 1996 to December 2019. Their demographic data, duration of symptoms before presenting to the hospital and duration of stay before surgery in the hospital were noted along with cause and level of obstruction. The type of procedure, any post-operative complications, mortality or re-exploration were also noted. Post-operative complications were graded as per Clavien Dindo classification. Results: A total of 986 patients presented with intestinal obstruction during this period out of which 743 patients underwent surgery. There were 429 (57.74%) males 314 (42.26%) females who had a mean age of 50.1 years (range 11 to 96 years). The commonest cause of obstruction was adhesions in 273 (36.7%) followed by carcinoma [130(17.5%)], tuberculosis [111(14.9%)], stricture [94(12.7%)] and hernia (5.4%) patients. Colorectal surgery was the most common previous procedure in the adhesive group [85(31.1%)]. Colon cancer was the common cause in carcinoma group. Ileum was the most common site of obstruction [329(44.3%)]. The overall operative mortality was 41 (5.5%). Conclusion: Postoperative adhesions are now the commonest cause of intestinal obstruction in our referral center with a comparable mortality rate with western reports. Though the etiology of intestinal obstruction is shifting towards the western pattern, tuberculosis, obstructed inguinal hernia still consists a major chunk of patients in developing countries.

Because of the increasing population and more waste generation, the area required for the disposal of MSW increases. Sanitary Landfill is one of the important method used for the disposal of MSW. The problem faced during new landfill sitting and availability of land is also increased simultaneously. Optimization of landfill sitting shows the prime importance at the environmental, social, and economic levels. The present work is carried out for the Solid Waste Management plant of Nashik Municipal Corporation (MH) India. As the landfill site is on the verge of the closure period, new landfill sitting identification is essential with consideration of all criteria to reduce environmental degradation and improve the standard of living of people nearby vicinity. This study aims to identify potential landfill sites for the year 2021 and the upcoming 25-year period, using a Remote Sensing (RS) - Geographical Information Systems (GIS) with Multi-Criteria Decision Analysis (MCDA). Fifteen parameters were considered while selecting a potential landfill site i.e., geomorphology, hydrogeology, distance to road, drainage, lineament, slope, LULC, distance to water bodies, population density used for AHP-MCDA. Airport, water bodies, road, habitation are used for restriction buffer analysis and aspect, while the wind rose diagram used for final site suitability. The weights of the 9 parameters were obtained from a constructed AHP matrix with a consistency ratio of 0.05557.During the study restricted zones were omitted. Afterward, the threshold limit and selection criteria were used for potential site selection. The study revealed several potential landfill sites and their suitability. Furthermore, the landfill area required for upcoming years is calculated based on the projected population, and the result of the potential landfill sites map shows the effectiveness of the proposed method. The results from this work showed the effectiveness of potential landfill site suitability for Environmental Sustainability in the selection process.
