SOME ELEMENTS OF CULTIVATION TECHNOLOGY OF WINTER BREAD WHEAT VARIETY ‘KRASA DONA’
Authors:   SSE “Agricultural research center «Donskoy»”, Sukharev A.A.
Published: December 2020

The climate of the Rostov region is gradually becoming arid. Therefore, winter wheat crops suffer from autumn drought, which results in germination decrease and the necessity to increase the seeding rate. However, new varieties developed in the Agricultural research center “Donskoy” have high energy of tillering both in autumn and in spring, which makes it possible to reduce the seeding rates without crop productivity decrease. The purpose of the current study was to determine the optimal seeding rates for soft winter wheat variety ‘Krasa Dona’ at different planting dates, which allow obtaining high yields with maximum economic efficiency of grain production. The trials were carried out in the southern part of the Rostov region in 2017–2019. The current study has shown that planting dates significantly affect the productivity of winter bread wheat variety ‘Krasa Dona’ sown after such preceding crops as weedfree fallow and sunflower. When the variety was sown in a weedfree fallow on September 10, the productivity was 7.43–7.62 t/ha, on September 20 it was 8.12–8.26 t/ha, on September 30 it was 7.96–8.11 t/ha, on October 10 it was 7.31–7.62, i.e. there was a significant difference between the variants with seeding rates only at the late sowing period. The seeding rate increase at the late sowing periods, even with profitability decrease, has contributed to an additional conditional net income of up to 1470–1670 rubles/ha due to productivity improvement. Depending on a sowing period, the productivity of the winter bread wheat sown after sunflower was 5.23–5.92 t/ha. Furthermore, an increase in seeding rate from 5 to 6–7 million/ha resulted in productivity increase only by 0.08–0.23 t/ha. When ‘Krasa Dona’ was sown on September 20, September 30 and October 10, the maximum conditional net income 27554–32174 rubles/ha at a seeding rate of 6 million/ha was obtained, that was 536–1064 rubles/ha more than in the variant with a seeding rate of 5 million/ha. Different planting dates and seeding rates had no significant effect on the qualitative traits of grain.

An assessment of the bioclimatic potential of agricultural territories is necessary to evaluate the utilization rate and the development of highly efficient zonal resource-saving farming systems. The purpose of the research was to assess the current level of the bioclimatic resources of the post-virgin regions of the Urals and Western Siberia to determine the levels of climatically provided yields, to identify the limiting factors and reserves of field agrocenoses productivity growth. Data on air temperature, precipitation level, air humidity deficit, and yield of grain crops (1990–2019) in the main post-virgin territories of the Orenburg, Kurgan, Omsk regions, and Altai Krai were the object of research. Comparative assessment of the biological productivity of the studied territories was carried out according to the method of D. I. Shashko in points in the context of average productivity. We established that the economic productivity of grain crops in the analyzed regions today was significantly lower than the potential one (calculated according to the bioclimatic potential (BCP)). Even if the grain yield in the Kurgan and Omsk regions is at the highest level (1.36–1.75 t/ha), the efficiency of BCP using is only 27–38 %. Precipitation is the main limiting climatic factor. Lack of precipitation against the background of growing amounts of effective temperatures is accompanied by an increase in air humidity deficits. The conducted studies allowed us to conclude that with the help of highly efficient use of bioclimatic resources in the post-virgin regions of the Urals and Western Siberia under the conditions of modern natural and anthropogenic changes, a significant (2.0–2.5 times) increase in the yield of grain crops is possible compared to the current level. As priorities, when developing adaptive technological methods, along with the careful implementation of technological discipline, one should also consider the technological methods aimed at more complete preservation of atmospheric precipitation and efficient use of soil moisture, including no-till technologies and components of “digital technologies”, as well as pay attention to the development of irrigation.
Writing and Weaving: The Textual and the Textile in Spenser’s 1590 Faerie Queene, III.i
Authors: Curbet Soler Joan
Published: December 2020

Most often, Ovidian allusions are woven into Edmund Spenser’s The Faerie Queene (Books I–III, 1590) without developing into an open re-telling of myths. One significant exception occurs in Book III, Canto 1: there the action comes to a temporary stop in order to make space for a detailed description of the tapestry in the hall of Castle Joyous, which depicts the story of Venus and Adonis. This article intends to offer a reading of that episode that focuses on the importance of materiality and self-reflexivity as keys to its significance at the opening of Book III, and in the larger structure of The Faerie Queene. Here, the descriptive powers of the poet are both foregrounded and questioned, in a double movement of ekphrasis which gestures towards a serious interrogation of the value of representation, both in poetry and the visual arts. Implicitly, it is the poet (and through him, the reader him/herself) that must question his/her role and participation in the gradual and often painful awareness of the body that is foregrounded throughout Book III.
Truth and Wonder in Richard Head’s Geographical Fictions
Authors: Villegas López Sonia
Published: December 2020

In line with the method prescribed by members of the Royal Society for natural history and travel writing, Richard Head explored the limits of verisimilitude associated with geographical discourse in his three fictions The Floating Island (1673), The Western Wonder (1674) and O-Brazile (1675). In them he argues in favor of the existence of the mysterious Brazile island and uses the factual discourse of the travel diarist to present a semi-mythical place whose very notion stretches the limits of believability. In line with recent critical interpretations of late seventeenth-century fiction as deceptive, and setting the reading of Head’s narrations in connection with other types of travel writing, I argue that Head’s fictions are a means of testing the readers’ gullibility at a time when the status of prose, both fictional and non-fictional, is subject to debate.
КВАЛІМЕТРИЧНЕ ДОСЛІДЖЕННЯ ЕЛЕМЕНТІВ ПРОЦЕСУ УЧІННЯ НА ПРИКЛАДІ ВИВЧЕННЯ ХІМІЧНИХ ДИСЦИПЛІН

Published: December 2020

У праці (Tkachuk, 2019) нами було розкрите формування технології учіння в процесі вивчення хімічних дисциплін у класичних університетах як головної складової навчального процесу. При цьому розглянуті можливості вирішення практичної реалізації всіх восьми запропонованих елементів технології учіння. Однак, в цій праці не вистачає аналізу впливу вхідних і вихідних параметрів елементів технології учіння. Крім того, кваліметрію результатів учіння потрібно розглядати як певний елемент технології учіння. Метою статті є виявлення функціональних зв’язків між вхідними і вихідними параметрами процесу учіння, виявлення на цій основі аналітичних співвідношень, що характеризують процес учіння, розгляд кваліметрії учіння не лише як засобу кількісної оцінки процесів якісного характеру, але як і певний елемент технології учіння. У роботі застосовані теоретичні методи дослідження, експериментальні методи виконання вимірювань фізичних величин, математичне моделювання та комп’ютерна обробка дослідних даних. У праці виявлено, що вихідні параметри досліджених п’яти елементів технології учіння мають не випадковий характер а підпорядковуються математичним законам. Гістограма розподілу підготовки до учіння описується законом рівномірного розподілу. Гістограма розподілу вихідного параметра сприймання має трапецеїдальний характер. Емпіричний закон розподілу вихідного параметра розуміння описується нормальним законом розподілу Гауса. Теоретичні закони вірогідності розподілу та закон розподілу густини вірогідності для запам’ятовування одержані як результат композиції закону розподілу Гауса та закону рівної вірогідності. Густина вірогідності розподілу кваліметричного оцінювання рівня забезпечення міцності знань визначається за законом Сімпсона і є розподілом по рівнобедреному трикутнику. Нами було досліджено п’ять елементів технології учіння. Подальші дослідження визначатимуть вихідні параметри наступних трьох елементів технології учіння і перевірку правдоподібності припущення, як узгоджуються емпіричні результати з гіпотезою про те, чи випадкова величина, яка розглядається, підпорядковується теоретичному закону розподілу. Важливим є питання, чи виявлена в емпіричних даних тенденція до залежності між двома випадковими є дійсно об’єктивною залежністю, або ж вона пояснюється випадковими причинами, що пов’язано з недостатнім обсягом досліджень.

Published: December 2020

The paper presents a sacred painting located on the road arch in St. Kazimierz Church in Lublin, which was forgotten for hundreds of years. The fresco was covered by several layers of paints dated from XIX and XX century. It survived likely because the space was too difficult for adaptation as an industry space. The space was used as a storage or a meeting room. Currently it works as a storeroom and a drying room for people living in the building. The present function is utterly incompatible with surrounding work of art you can see on the wall.

Users of online games knowdays are increasingly widespread. The duration of playing online games is not recommended more than 4 hours a day. If it exceeds this time, the eyes tend to experience fatigue. Eye fatigue is a dependence on the eyes and is caused by a disturbing sense of vision in the work that requires the ability to see for a long time. In Senior High School 1, students can spend 2-4 hours per day playing online games continuously without adequate rest periods. The aims of the study to determine the relationship of playing online games with complaints of eye fatigue of the students in Senior High School 1 in Delitua. This research used an analytical study with a cross-sectional approach. The sample is 96 students with purposive the sampling technique.

Implication Statement
Acutely traumatic clinical events can exacerbate stress and burnout amongst healthcare providers.  The Simulated Training for Resilience in Various Environments (STRIVE) course may provide a useful framework for medical educators to teach stress management skills to promote resilience amongst physician trainees. The course introduces the Big Four+ techniques (goal setting, visualization, self-talk, progressive muscular relaxation, attention control and tactical breathing) created by the Canadian Armed Forces using clinical scenarios. This framework can be easily adapted across other training contexts to equip future clinicians with a foundational skill set to optimize their response and recovery following critically stressful incidents.
CrowdDetective: Wisdom of the Crowds for Detecting Abnormalities in Medical Scans
Authors: Cheplygina Veronika
Published: December 2020

Machine learning (ML) has great potential for early diagnosis of disease from medical scans, and at times, has even been shown to outperform experts. However, ML algorithms need large amounts of annotated data – scans with outlined abnormalities - for good performance. The time-consuming annotation process limits the progress of ML in this field. To address the annotation problem, multiple instance learning (MIL) algorithms were proposed, which learn from scans that have been diagnosed, but not annotated in detail. Unfortunately, these algorithms are not good enough at predicting where the abnormalities are located, which is important for diagnosis and prognosis of disease. This limits the application of these algorithms in research and in clinical practice. I propose to use the “wisdom of the crowds” –internet users without specific expertise – to improve the predictions of the algorithms. While the crowd does not have experience with medical imaging, recent studies and pilot data I collected show they can still provide useful information about the images, for example by saying whether images are visually similar or not. Such information has not been leveraged before in medical imaging applications. I will validate these methods on three challenging detection tasks in chest computed tomography, histopathology images, and endoscopy video. Understanding how the crowd can contribute to applications that typically require expert knowledge will allow harnessing the potential of large unannotated sets of data, training more reliable algorithms, and ultimately paving the way towards using ML algorithms in clinical practice.
The challenges of public speaking in the wings of culture

Published: December 2020

As a content producer and presenter of the radio show program, "The Wings of Culture", broadcasted live every Friday on Radio Ribat Fm, Monastir, I have faced different challenges. This paper draws on my personal experience to examine the various challenges I have so far met while presenting the program. My presentation tackles in its first part how the radio host should inform, instruct, and entertain simultaneously the audience especially that the program targets British and American literature and civilisation. The second important challenge to address is how to use voice, word choice, and pitch in order to enact an effective public performance, and accordingly help the audience create the required mental picture specifically in the condition of the absence of a visual image. The third part, however, is devoted to talk about how to manage time, work under pressure, and have quick thinking particularly when engaging in conversation with a guest.
First record of Reimerothrix floridensis (Fragilariaceae: Bacillariophyta) for Mexico.
Authors: Hernández -Almeida O. U. , Herrera -Silva J. A.
Published: December 2020

Reimerothrix floridensis is part of a group of arcuate-shaped diatoms that are generally confused with Cylindrotheca closterium, Psammosynedra closterioides and Nitzschia longissima var. reverse. In this work presents the first record of the arcuate diatom Reimerothrix floridensis, collected in Dzilam de Bravo (north coast of the Yucatan Peninsula) in the southern tip of the Gulf of Mexico. This find was carried out within the framework of the identification of the diatom species that formed a proliferation of phytoplankton raised on the coasts of the Yucatan Peninsula during 2011, and where C. closterium and N. longissima var. Reversa were dominant species. The characteristics of R. floridensis coincide with the original description of the species, except for the areolas associated with the sternum. Since this species had only been recorded in Florida Bay, your observation in Mexico on the north coast of the Yucatan Peninsula represents its southernmost record, which extends the geographic range of this species. On the other hand, because the observation of R. floridensis was carried out During the presence of a proliferation of C. closterium and N. longissima, species with which it is generally confused, the importance of making careful taxonomic determinations accompanied by detailed descriptions that give certainty to ecological studies.
Taxonomic inventory of Hydrozoa (Order: Anthoathecata) and Anthozoa (Subclass: Hexacorallia, Octocorallia) of the Enmedio reef, Lobos-Tuxpan Reef System
Authors: De la Cruz -Francisco Vicencio , González -González Marlene , Morales -Quijano Itzel
Published: December 2020

The present work reports the first inventory of corals, sea anemones, zoanthids and octocorals ofthe Enmedio reef, ecosystem that is part of the Lobos-Tuxpan Reef System. The information was gathered during the April 2014-November 2015 period. Five sampling sites were established in the leeward, flatland and windward area. At each site random surveys were carried out to record species. The reef areas were characterized by considering the number of species recorded and using the Jaccard index to determine differences/similarities. A total of 46 species were recorded, which are   represented by two classes, six orders, 25 families and 31 genera. The order Scleractinia was the most diverse in species. There is an extension in the distribution range of Palythoa grandis and Eunicea mammosa for the southwest Gulf of México. Ten species of sea anemones and five species of scleractinian corals were added as new records to the Lobos-Tuxpan Reef System. The reef areas are dissimilar in species composition and define a marked zonation. The leeward zone had the most importance because it has the highest species richness, an attribute that decreases towards the windward zone. The Enmedio reef is consideredimportant in species diversity and merits special attention because it includes three species with special protection status (Acropora cervicornis, Acropora palmata y Plexaurella dichotoma) according to Mexican laws.
Hydrographic characteristics off the coast of Bahia Magdalena, BCS, Mexico during El Niño 2015.
Authors: CERVANTES-DUARTE RAFAEL , GARCíA-ROMERO FELIPE DE JESUS
Published: December 2020

During 2015 an El Niño was recorded in the Eastern Pacific coast, which produced different environmental effects along the coasts of Mexico. The aim of this study was to describe the  hydrological conditions,nutrients and chlorophyll variations along the coast of Bahia Magdalena, during 2015. Monthly samples were obtained during neap tides in 9 sites located within the lagoon margins. Temperature and salinity were measured in each sampling site using a CTD. Surface, midwater and bottom samples of seawater were obtained to measure nutrient concentrations (ammonium, nitrite, nitrate, phosphate and silicate) and chlorophyll a. The sea surface temperature data evidenced the presence of the El Niño, with values above the annual average (> 2.5 oC in July and August) with the domain of Subtropical Surface Water in the second semester. The water column was generally mixed, except in the warmer months, when some sites showed stratification. Nutrients mean values at surface,except silicate, tended to be lower than previously recorded, especially in the upwelling season. Chlorophyll data in the water column showed a wide range (0.05 to 12.94 mg m-3) with maximum values in midwater and bottom from April to June and minimum values in August and September. The warming effect produced by El Niño in neritic waters could have being mitigated by local processes, such as turbulent mixing, which may have carried nutrients to the mixed layer maintaining high biomass of phytoplankton and zooplankton. However, changes in Magdalena Bay were sufficient to modify the trophic web and produce an impact on the distribution and abundance of organisms in the area.
Spatial distribution of abalone (Haliotis fulgens and H. corrugata) and its time variability; implications for their management.
Authors: Guzmán -Del Próo Sergio , Borges -Souza José Manuel
Published: December 2020

Abalone fisheries in the central pacific coast of Baja California relies on the exploitation of Haliotisfulgens (green abalone) and H. corrugata (pink abalone). Their catch is regulated under a quotas system annually assessed by the fisheries authority. Because they are sedentary species it is assumed that their density and biomass are roughly constant along the time. Thus, annual biomass assessments are realized only once a year. However, a central question emerges: whether this assumption is true, or density and biomass are changing even in a short time? To respond this question, submarine surveys were carried out at different times, in eight reefs along the same fixed sampling stations. Results showed that both the density and spatial distribution changed just after 24 and 72 h. Similar changes were observed 24 days later. Total abundance changed from 79 specimens at the beginning of the experiment to 46 at the end. In some sites, abundance falls less than 50 %. Changes in spatial distribution wereobserved commonly. The average of the minimum distance within the abalone patches was 0.5 m; however, most patches were only of 2 individuals. We conclude that it is necessary to undertake more than one annual survey assessment to attain average confident figures of density and biomass population, with less uncertainty. Furthermore,assessments should include measurement of size and frequency of the patches, which should be numerous enough to guarantee a successful reproduction, in-order-to maintain the stocks at a sustainable level.

INVESTIGATIONS ON MESOPHOTIC CORAL ECOSYSTEMS IN CUBA (1970-1973) AND MEXICO (1983-1984)

After a pioneering study of Jamaican coral reefs, the Cuban archipelago was the second to be surveyed by SCUBA for scleractinian corals and reef life to a depth of 90m, sampling all phenotypes.Â  Regrettably, the published data on the mesophotic coral ecosystems (MCEs) of Cuba, collected 1970 to 1973, have been ignored.Â  This is also true for the published data on the MCEs of the Mexican Yucatán Peninsula, collected 1983 to 1984.Â  These two investigations described immense areas exhibiting a rich continuum of coral life, from shallow reefs into MCEs without scleractinian faunal break, and no depth-specialists species complex.Â  Instead, a morphological changeover of three-dimensional corallum into two-dimensional corallum was observed and documented.Â  The existing data on the Cuban and Mexican MCEs (now 45 and 34 years old, respectively) present a unique opportunity for long-term status and ecosystem trends analysis.Â  MCEs require terminological clarification from collaborative efforts to effectively use the globally available data.Investigaciones sobre ecosistemas coralinos mesofóticos en Cuba (1970-1973) y México (1983-1984)RESUMEN. Después de un estudio pionero en arrecifes de Jamaica sobre corales escleratinios y vida arrecifal, el archipiélago cubano fue el segundo que se estudió mediante buceo SCUBA a profundidades de hasta 90m, incluyendo muestras de todos los fenotipos. Infortunadamente, los datos publicados sobre ecosistemas coralinos mesofóticos (ECM), recabados entre 1970 y 1973 han sido soslayados, al igual que los datos publicados sobre los ECM de la Pení­nsula de Yucatán, México, recabados entre 1983 y 1984.Â  Ambas investigaciones describen áreas inmensas que exhiben un rico continuo de vida coralina, desde arrecifes someros hasta ECM sin ruptura en la fauna escleratinia y sin complejos de especies especialistas de profundidad. En vez de esto, se observó y documentó un reemplazamiento de formas tridimensionales de corales por formas bidimensionales.Â  La información existente sobre ECM cubanos y mexicanos con antigüedades de 45 y 34 años, respectivamente ofrecen una oportunidad única para realizar análisis sobre estatus a largo plazo y tendencias de ecosistema.Â  Los ECM requieren aclaración terminológica de esfuerzos de colaboración para utilizar efectivamente los datos disponibles globalmente.

Previous studies have demonstrated that macro-scale climatic events such as ENSO, cause changes in meteorological and hydrological conditions, inducing physicochemical changes in the water column, as well as in coastal and estuarine communities in the Atlantic Ocean. Rio de la Plata (RdlP) is the second largest estuary of South America, where ENSO is a macro-scale environmental driving force. In this paper, the species composition, abundance, as well as the temporal and horizontal variation of the mesozooplankton in the north coast of the RdlP during 2009-2010 ENSO were analyzed. Zooplankton samples were collected with sub-surface trawls in fifteen stations during eleven sampling surveys. Physico-chemical parameters of the water column (temperature, salinity, dissolved oxygen, turbidity, and chlorophyll a) were determined and related to the RdlP flows. The holoplankton was dominated by estuarine copepod (Acartia tonsa), freshwater cladocerans (Bosmina hagmanni, Ceriodaphnia dubia, Moina sp.), and in the meroplankton, barnacle larvae were the most abundant group. Temporal variability was reflected in abundance differences and ecological indexes between both ENSO phases. The copepods abundance showed a positive association with RdlP flow during El Niño (Nov 2009-Apr 2010), and negative during La Niña-Neutral (Sep 2010-Jan 2011). During El Niño months, the higher richness of typical freshwater cladocerans was observed, promoting a horizontal heterogeneity in the study area. During La Niña-Neutral, the zooplankton showed lower species richness and was dominated by copepods typical of the RdlP (Acartia tonsa). Canonical Correspondence Analysis showed that salinity, RdlP flow, and chlorophyll a explained 88.4% of the total variance of the species-environment relationships. This paper presents new information on zooplanktonic organisms’ response to climatic and hydrological events in the RdlP estuary.

The course of the COVID‑19 pandemic imposes a significant burden on healthcare systems, including on primary care, when it is necessary to correctly suspect and determine further management. The symptoms non-specificity and the manifestations versatility of the COVID‑19 impose difficulties in identifying suspicions. To improve the definition of COVID‑19 symptom checkers and medical decision support systems (MDSS) can potentially be useful. They can give recommendations for determining the disease management. The scientific analysis shows the manifestations versatility and the occurrence frequency COVID‑19. We structured the manifestations by occurrence frequency, classified them as “large” and “small”. The rules for their interaction were determined to calculate the level of suspicion for COVID‑19. Recommendations on patient management tactics were developed for each level of suspicion. NLP models were trained to identify the symptoms of COVID‑19 in the unstructured texts of electronic health records. The accuracy of the models on the F-measure metric ranged from 84.6% to 96.0%. Thus, a COVID‑19 prediction method was developed, which can be used in symptom checkers and MDSS to help doctors determine COVID‑19 and support tactical actions.

This study investigates the interaction effects of process variables on photocatalytic phenol degradation in oil produce water. A series of ZnO/Fe2O3 nanocomposite prepared using the sol-gel method and calcined at a temperature range of 400-600 oC were employed as photocatalysts. The characterization analysis using different instrument techniques revealed that the ZnO/Fe2O3 nanocomposites have suitable physicochemical properties as photocatalysts. The photocatalytic activity of the ZnO/Fe2O3 nanocomposite was examined in photo-reactor considering the degradation of the phenol and the reduction in chemical oxygen demand (COD) in the oilfield produced water under direct sunlight. It was ascertained that process variables such as irradiation time, calcination temperature of the ZnO/Fe2O3 nanocomposites, and the ZnO/Fe2O3 nanocomposites concentration significantly influenced the chemical oxygen demand and phenol removal. Based on the analysis of variance (ANOVA), the effects of the process variables on the phenol and COD removal can be ranked as irradiation time (p-value < 0.0001) > calcination temperature of the ZnO/Fe2O3 nanocomposite (p-value = 0.0003) > ZnO/Fe2O3 concentration (p-value = 0.0013). The interaction between the parameters was observed to have a substantial effect on COD and phenol removal. However, the interaction effect that produced the most significant influence on the COD and phenol removal was recorded between the irradiation time and the ZnO/Fe2O3 nanocomposite concentration.

Authors: Alamir Mahmoud A. , Che Sidik Nor Azwadi
Published: December 2020

Thermoacoustic refrigerators and heat pumps are considered one of the important emerging green technologies. They are based on the use of acoustic pressure waves to supply cooling or heating effects. The oscillating gas interaction with a solid wall called the stack generates thermoacoustic effects. This study presents the effects of the operating conditions and geometric parameters on the temperature difference across the stack and the coefficient of performance of a thermoacoustic heat pump at different cooling loads. The design steps of these systems were also demonstrated. Theoretical study of the operation conditions and geometric parameters was presented using “DeltaEC”. The results showed that higher harmonics are less desirable for thermoacoustic phenomena as they lower the temperature difference across the stack. Further insights into the effects of amplitude pressure, mean pressure and stack geometries were also demonstrated. This study helps to establish the concepts and design steps for thermoacoustic refrigerators and heat pumps.

Construction workers are particularly susceptible to heat-related illnesses, for the weather is very hot and humid. The objective of this study is to investigate the interaction between the temperature and relative humidity to the physiological parameters such as heart rate (HR) and volume oxygen uptake (VO2 max) of the workers in the construction industry. The experiment was conducted in an environmental chamber which simulates the environment of the construction industry with three conditions combining air temperature and relative humidity (34 °C/74 %, 34 °C/92 %, 38 °C/83 %). The HR and the VO2 max of three subjects were monitored, and all the data were continuously recorded every 15 minutes. For each condition, the activity levels such as lifting the heavy sand (10 kg) were conducted for subjects. In the VO2 case, a significant correlation was observed between air temperature (p=0.043) and the relative humidity (p=0.000). Meanwhile, in HR case, a significant correlation was also observed between air temperature (p=0.004) and the relative humidity (p=0.028). The high-risk thermal environment (38 °C/83 %) and subject were identified. In conclusion, it can be empirically proved that environmental factor such as temperature and relative humidity have a significant impact on workers’ performance.
