With the strengthening of human activities, more and more sulfur had entered soil system. The sulfur pollution of soil had threaten environment and human health. This paper reviews the status, sources and danger of sulfur pollution soils, and the physical-chemical remediation and bioremediation technology are also discussed. In addition, the future study on remediation technology for sulfur pollution soils was prospected.

Environment refers to the entire physical and biological world. In which organisms live, grow, thrive and develop their natural tendencies. The truth is that the existence of life is basically dependent on the environment. Changes in the physical, chemical or biological characteristics of any element of the environment that are harmful to humans or other beings is called environmental pollution.Environmental pollution has taken the form of a worldwide problem today and in India also this problem is seen in various forms. Due to industrial and technological development, rapid population growth, urbanization etc., the environmental pressure started increasing. Today, the greatest need is "destruction-free development" but due to human activities, environmental imbalance increases, which pollutes the environment and endangers the existence of other animals and flora including humans. Environmental pollution affects human health, causing fatal diseases. पर्यावरण का तात्पर्य समूचे भौतिक एवं जैविक विश्व से है। जिसमें जीवधारी रहते हैं, बढ़ते हैं, पनपते हैं और अपनी स्वाभाविक प्रवृत्तियों का विकास करते हैं। सत्य तो यह है कि जीवन का अस्तित्व मूलतः पर्यावरण पर निर्भर है। पर्यावरण के किसी भी तत्व के भौतिक, रासायनिक अथवा जैविक विशेषताओं में परिवर्तन जो मानव या अन्य प्राणियों के लिए हानिकारक हो पर्यावरण प्रदूषण कहलाता है। पर्यावरण प्रदूषण आज एक विश्वव्यापी समस्या का रूप ले चुका है और भारत में भी यह समस्या विविध रूपों में दृष्टिगत होती है। औद्योगिक एवं तकनीकी विकास, तीव्र जनसंख्या वृद्धि, शहरीकरण आदि के कारण पर्यावरण के दबाव में निरन्तर बढ़ोतरी होने लगी। आज सबसे बड़ी आवश्यकता है ‘‘विनाश रहित विकास’’ किन्तु मानवीय क्रियाकलापों से पर्यावरणीय असंतुलन बढ़ता ही जाता है जिससे पर्यावरण प्रदूषित हो जाता है और मानव सहित अन्य प्राणियों एवं वनस्पतियों का अस्तित्व खतरे में पड़ता जा रहा है। पर्यावरण प्रदूषण मानवीय स्वास्थ्य को प्रभावित करता है जिससे घातक रोग उत्पन्न होते हैं।

This study explored the underlying processes associated with the policy of increasing qualified physical education teachers (QPETs) in Singapore primary schools. Data were collected from the National Archives of Singapore, Newslink, NewpaperSG and documents. An ‘archaeological analysis’ by Foucault (1972) was used to trace the discursive conditions which enabled and facilitated the policy. Three distinct elements were borrowed from ‘The Archaeology of Knowledge and the Discourse on Language’, namely: the status – as reflected in the positions of individuals influencing the PE policies and initiatives; the institutional sites – as in the locations of the decisions being exercised, and; the situation – identified by the key events leading to the decision to increase QPETs in primary schools. The conclusions based on the analysis of these elements offer a clearer understanding of the various contributions to the adoption of the policy and serve to provide an insightful lens to policymakers who might seek to redesign the future shape of Physical Education.

Alvin Toffler’s writings encapsulated many of the tensions of futurism: the way that futurology and futures studies oscillated between forms of utopianism and technocracy with global ambitions, and between new forms of activism, on the one hand, and emerging forms of consultancy and paid advice on the other. Paradoxically, in their desire to create new images of the future capable of providing exits from the status quo of the Cold War world, futurists reinvented the technologies of prediction that they had initially rejected, and put them at the basis of a new activity of futures advice. Consultancy was central to the field of futures studies from its inception. For futurists, consultancy was a form of militancy—a potentially world altering expertise that could bypass politics and also escaped the boring halls of academia.

AbstractThis research quantitatively and qualitatively analyzes the factors responsible for the water level variations in Lake Toba, North Sumatra Province, Indonesia. According to several studies carried out from 1993 to 2020, changes in the water level were associated with climate variability, climate change, and human activities. Furthermore, these studies stated that reduced rainfall during the rainy season due to the El Niño Southern Oscillation (ENSO) and the continuous increase in the maximum and average temperatures were some of the effects of climate change in the Lake Toba catchment area. Additionally, human interventions such as industrial activities, population growth, and damage to the surrounding environment of the Lake Toba watershed had significant impacts in terms of decreasing the water level. However, these studies were unable to determine the factor that had the most significant effect, although studies on other lakes worldwide have shown these factors are the main causes of fluctuations or decreases in water levels. A simulation study of Lake Toba's water balance showed the possibility of having a water surplus until the mid-twenty-first century. The input discharge was predicted to be greater than the output; therefore, Lake Toba could be optimized without affecting the future water level. However, the climate projections depicted a different situation, with scenarios predicting the possibility of extreme climate anomalies, demonstrating drier climatic conditions in the future. This review concludes that it is necessary to conduct an in-depth, comprehensive, and systematic study to identify the most dominant factor among the three that is causing the decrease in the Lake Toba water level and to describe the future projected water level.

Incidence of ischemic stroke and transient ischemic attack in young adults is rising. However, etiology remains unknown in 30–40% of these patients when current classification systems designed for the elderly are used. Our aim was to identify risk factors according to a pediatric approach, which might lead to both better identification of risk factors and provide a stepping stone for the understanding of disease mechanism, particularly in patients currently classified as “unknown etiology”. Risk factors of 656 young stroke patients (aged 18–50) of the FUTURE study were categorized according to the “International Pediatric Stroke Study” (IPSS), with stratification on gender, age and stroke of “unknown etiology”. Categorization of risk factors into ≥1 IPSS category was possible in 94% of young stroke patients. Chronic systemic conditions were more present in patients aged <35 compared to patients ≥35 (32.6% vs. 15.6%, p < 0.05). Among 226 patients classified as “stroke of unknown etiology” using TOAST, we found risk factors in 199 patients (88%) with the IPSS approach. We identified multiple risk factors linked to other mechanisms of stroke in the young than in the elderly . This can be a valuable starting point to develop an etiologic classification system specifically designed for young stroke patients.

Augustan poets refer curiously often to the possible composition of a Gigantomachy, as in Prop. 2.1 and 3.9, Ov. Am. 2.1.11 ff., Trist. 2.61 ff. and 331 ff., and the future study of natural philosophy, as in Verg. Georg. 2.475 ff. and Prop. 3.5.25 ff. These ambitions are rejected, abandoned, or firmly set in the future. I suggest that the function of both is closely similar since they provide traditionally sublime themes to contrast the poet's present ‘humbler’’ task.

There are various signs indicating that the Earth's natural environment is changing toward unfavorable direction for species, which is highly suspected to be connected with human activities. In the last century, people all over the world have realized the severity of environmental issues. In the long history, Chinese ancient had already development good rules and methods to reach balance between economic development and environment sustainability. This paper will discuss how environmental concepts forms and which methods could be applied in the future.
