The Relationship

The physical environment of classrooms has a strong relationship with student learning performance and health. Since the outbreak of COVID-19 in 2019, almost all universities have begun implementing closed instructional management, which has forced students to spend a much longer amount of time inside the classroom. This has also led to an increasing problem of thermal comfort in classroom indoor environments. In this paper, classrooms evolved from three dominant teaching modes at Zhejiang Sci-Tech University (ZSTU), located in the Hot Summer and Cold Winter (HSCW) zone of China, were selected as experimental spaces. Meanwhile, 12 learning groups with 60 students (30 of each sex) were selected as the tested samples. The relationship between thermal comfort and learning efficiency of the tested students was established through thermal comfort questionnaires and learning efficiency tests under the typical natural conditions in transition seasons. Based on this, improvement strategies were proposed for the current state of the classroom environment, providing a database for optimizing the environmental conditions of university classrooms in HSCW zone on the basis of improving students’ learning efficiency.

Hostel buildings prime objective is to provide better thermal environments to the students for their good health and learning performance. In India, a very few studies are done on the thermal environments of multi-storied naturally ventilated hostel buildings. We carried out a thermal comfort study in two mid-rise (~G+5 floors) naturally ventilated (NV) hostel buildings during monsoon season (August-September, 2018). The field study conducted for three consecutive weeks collecting 642 valid subjective responses with objective information regarding thermal parameters of 253 rooms. Statistical analysis of student’s responses and measured thermal environment variables was performed for assessing inter buildings effects, different weather conditions (rainy or cloudy) and daytime duration (morning, afternoon and evening), respectively. The study finds the mean thermal neutrality at 29.9°C for the studied group using Griffiths’ method. The results suggested that more than 80% of subjects were voting within central three categories when indoor operative temperature ranged between 28-32.1°C. The primary adaptive action of occupants includes switching on the fans (100%) followed by the opening of external doors (80%) and opening or closing of windows (55%) to restore thermal comfort in built environments.

ABSTRACT. The purpose of this study is to carry out a climatological analysis of human thermal comfort in the São Paulo city, Brazil, for outdoor and indoor environments, applying different indexes of thermal comfort in order to assess which of them represent best the weather characteristics of the São Paulo city. The relationship between these indexes and the seasons (fall, winter, spring, summer) was investigated in the period from 1980 to 2005, for outdoor environments, and during 2005, for the indoor environments. The results showed that the most appropriate index for São Paulo, both for internal and external conditions was the Effective Temperature Index (ET) as it has a broad classification and can provide appropriate representations of the region’s comfort. According to this index, the mornings during summer in the outdoor environments showed mild discomfort by cold, and the afternoons were comfortable. In winter, there was thermal stress by cold during the mornings and a slight discomfort by cold during the afternoons. For indoor environments in the summer, most of the houses presented comfortable mornings, and afternoons with discomfort in relation to the heat, while in the winter, period proved to be uncomfortable and stressful due to cold and the afternoonscharacterized themselves as comfortable.Keywords: thermal sensation, biometeorology, biometeorological indexes.RESUMO. O objetivo deste estudo é realizar uma análise climatológica do conforto térmico humano na cidade de São Paulo, Brasil, para ambientes externos e internos, aplicando diferentes índices de conforto térmico, a fim de avaliar qual deles melhor representa as características climáticas da cidade de São Paulo. A relação entre esses índices e as estações do ano (outono, inverno, primavera, verão) foi investigada no período compreendido entre 1980 e 2005 para os ambientes externos, como também durante o ano de 2005 para os ambientes internos. Os resultados mostraram que o índice de Temperatura Efetiva (TE) é o mais apropriado para São Paulo, tanto para condições internas quanto externas, pois este possui uma classificação ampla e pode fornecer representações adequadas do conforto da região. Segundo esse índice, as manhãs, durante o verão nos ambientes externos, apresentaram leve desconforto por frio, e as tardes estiveram confortáveis. Já no inverno, observou-se estresse térmico por frio durante as manhãs e um ligeiro desconforto por frio no período das tardes. Para os ambientes internos, a maioria das casas apresentou no verão manhãs confortáveis e tardes com desconforto em relação ao calor; já no inverno, o período das manhã mostrou-se desconfortável e estressante devido ao frio e as tardes caracterizaram-se como confortáveis.Palavras-chave: sensação térmica, biometeorologia, índices biometeorológicos.

Abstract Introduction: Epilepsy is either; idiopathic when there is no underlying cause or secondary if there is an underlying cause of egg brain tumors, stroke. There is a strong in conjunction between epilepsy and valvular lesions. Objective: To study the relationship between valvular lesions and Epilepsy among Sudanese epileptic patients. Methodology: Almost 50 Sudanese patients with valvular lesions were included in the study during Jane 2018 to Jane 2019. Result: Out of 50 patients (48%) males while females (52%). Almost 40% of the patients were found to have generalized tonic colonic epilepsy, while 60% have focal epilepsy. Pure MS was the common valvular lesion observed. 14% of the patients had atrial fibrillation, especially with mitral stenosis .4% of the patients underwent valvotomy. Abnormal EEG was observed in 64% of the patients. Abnormal brain MRI was detected in 50% of the patients. Almost all the patients 100% diagnosed as having valvular lesions before being diagnosed with epilepsy. Conclusion: There is a strong relationship between valvular lesions and epilepsy, most probably due to association with coexist arrhythmias resulting in cerebral infarction, tight valvular lesions, and rarely follow valvotomy valvular replacement.

The status of tafsīr and Qur'anic studies in the Islamic Republic of Iran has changed significantly during recent decades. The essay provides an overview of the state of Qur'anic studies in Iran today, aiming to examine the extent of the impact of studies by Western scholars on Iranian academic circles during the last three decades and the relationship between them. As in most Islamic countries, the major bulk of academic activity in Iran in this field used to be undertaken by the traditional ʿulamāʾ; however, since the beginning of the twentieth century and the establishment of universities and other academic institutions in the Islamic world, there has been increasing diversity and development. After the Islamic Revolution, many gradual changes in the structure and approach of centres of religious learning and universities have occurred. Contemporary advancements in modern sciences and communications technologies have gradually brought the institutions engaged in the study of human sciences to confront the new context. As a result, the traditional Shīʿī centres of learning, which until 50 years ago devoted themselves exclusively to the study of Islamic law and jurisprudence, today pay attention to the teaching of foreign languages, Qur'anic sciences and exegesis, including Western studies about the Qur'an, to a certain extent, and recognise the importance of almost all of the human sciences of the West.

This study examines the influence of receivables on liquidity at PT. Graha Tumarima. Sukabumi City for 5 years, with a sampling technique using a purposive sample in the form of financial statement data from 2010 to 2014 using a table of trade receivables and company liquidity. In this study, researchers refer to the theory of Bambang Riyanto (2008: 94) as the connecting theory of the title. This study aims to determine whether there is a relationship and influence between receivables and liquidity at PT. Graha Tumarima. The research design uses the method of exposing the facto, the method of data collection aims to test the hypothesis by using correlation analysis, determination, regression and hypothesis testing with t-test. The results of this study show the influence of receivables on liquidity is shown by the value of r = 0.888, meaning that receivables have a very strong relationship to liquidity. The nature of the relationship is positive, meaning that if the value of cooperative credit is higher the liquidity will be higher. Conversely, if the value of receivables decreases, liquidity will decrease. The magnitude of the influence of receivables on liquidity is shown by the value of R Square / Determination Coefficient of 0.789 or 78.9% thus the receivables have an effect of 78.9% on cooperative liquidity. Hypothesis testing uses the t test, that t arithmetic = 3.347 while t table = 3.182 means t arithmetic> t table. Means that Ho is rejected and Ha is accepted. There is an influence between the receivables on liquidity at PT. Graha Tumarima, Sukabumi City

Abstract We perform a lattice study of double parton distributions in the pion, using the relationship between their Mellin moments and pion matrix elements of two local currents. A good statistical signal is obtained for almost all relevant Wick contractions. We investigate correlations in the spatial distribution of two partons in the pion, as well as correlations involving the parton polarisation. The patterns we observe depend significantly on the quark mass. We investigate the assumption that double parton distributions approximately factorise into a convolution of single parton distributions.

Abstract Background Language delay is one of the major referral criteria for an autism evaluation. Once an autism spectrum diagnosis is established, the language prognosis is among the main parental concerns. Early language regression (ELR) is observed by 10–50% of parents but its relevance to late language level and socio-communicative ability is uncertain. This study aimed to establish the predictive value of ELR on the progression of language development and socio-communicative outcomes to guide clinicians in addressing parents’ concerns at the time of diagnosis. Methods We used socio-communicative, language, and cognitive data of 2,047 autism spectrum participants from the Simons Simplex Collection, aged 4–18 years (mean = 9 years; SD = 3.6). Cox proportional hazard and logistic regression models were used to evaluate the effect of ELR on language milestones and the probability of using complex and flexible language, as defined by the choice of ADOS module at enrollment. Linear models were then used to evaluate the relationship of ELR and non-verbal IQ with socio-communicative and language levels. Results ELR is associated with earlier language milestones but delayed attainment of fluent, complex, and flexible language. However, this language outcome can be expected for almost all autistic children without intellectual disability at 18 years of age. It is mostly influenced by non-verbal IQ, not ELR. The language and socio-communicative level of participants with flexible language, as measured by the Vineland and ADOS socio-communicative subscales, was not affected by ELR. Limitations This study is based on a relatively coarse measure of ultimate language level and relies on retrospective reporting of early language milestones and ELR. It does not prospectively document the age at which language catches up, the relationship between ELR and other behavioral areas of regression, nor the effects of intervention. Conclusions For autistic individuals with ELR and a normal level of non-verbal intelligence, language development follows a “bayonet shape” trajectory: early first words followed by regression, a plateau with limited progress, and then language catch up.

In the developing economy, tourism is the most visible and steadiest growing facade. Tourism is considered one of the rapidly increasing elements for economic development from the last two decades. Therefore, the proposed study used vector autoregression (VAR) model, error correction model (ECM), and the Granger causality to check the relationship between the tourism industry and economic growth based on the data of the Beijing municipal bureau of statistics from 1994 to 2015. Gross domestic product (GDP) is used as a replacement variable for the economic growth index, while internal tourism revenue is used as a tourism industry indicator. The study supports the tourism-led growth hypothesis proposed in the existing literature in a different survey of tourism and economic development. The results show that there is a strong relationship in the tourism industry and economic growth in the context of Beijing, and at the same time, tourism creates a more significant increase in long run local real economic accomplishments. The results of the VAR model confirm that in the long run, Beijing’s economic growth is affected by domestic tourism, while the ECM model shows unidirectional results in the short term. Similarly, there is a one-way causal relationship between the tourism industry and economic growth in Beijing, China. The empirical results are in strong support of the concept that tourism causes growth.
