We rely on clean water to sustain human life, ecosystems, and food supply. In Florida and southwest Georgia, the Floridan Aquifer supplies much of the water we use. As populations grow and regional economies expand, the impacts of human activity on water pollution become more widespread. We must take preventative actions to minimize water pollution to maintain the quality of our water sources, and thus, our quality of life.

ABSTRACTThis research was conducted to determine the status of Lake Toba water quality in the area of Toba Samosir (Tobasa) Regency and the feasibility of its use. This study revealed that BOD, COD, iron and free Cl2 of Lake Toba Tobasa regency exceed water quality criteria for Class I and Class II based on Governor Decree No. 1 Year 2009 on Raw water quality of Lake Toba in North Sumatera. High COD and BOD values imply that Lake Toba water was polluted by organic matter presumably originated from floating net cages (KJA), while free Cl2 is thought to originate from domestic waste activities in Parapat City and its surroundings. In general, it was concluded that the water of Lake Toba in the Tobasa Regency did not meet the criteria for clean water and water tourism.Keywords: Lake Toba, raw water, pollution, water qualityABSTRAKPenelitian ini dilakukan untuk mengetahui kualitas air Danau Toba wilayah Kabupaten Toba Samosir (Tobasa) dan kelayakan peruntukannya. Penelitian ini mengungkapkan bahwa air Danau Toba wilayah Kabupaten Tobasa memiliki BOD, COD dan konsentrasi besi dan Cl2 bebas melebihi kriteria mutu air Kelas I dan Kelas II pada Peraturan Gubernur Sumatra Utara No 1 Tahun 2009. Tingginya nilai COD dan BOD mengisyaratkan bahwa perairan Danau Toba tercemar oleh bahan organik yang diduga berasal keramba jaring apung (KJA), sedangkan Cl2 bebas diduga berasal dari limbah domestik kegiatan Kota Parapat dan sekitarnya. Secara umum disimpulkan bahwa air Danau Toba di wilayah Kabupaten Tobasa tidak/belum memenuhi kriteria untuk air baku air minum  dan wisata air.Kata kunci: danau Toba, bahan baku air, pencemaran, baku mutu

The scientific problem of economics “Managing the quality of human life” is formulated on the basis of artificial intelligence, algebra of logic and logical-probabilistic calculus. Managing the quality of human life is represented by managing the processes of his treatment, training and decision making. Events in these processes and the corresponding logical variables relate to the behavior of a person, other persons and infrastructure. The processes of the quality of human life are modeled, analyzed and managed with the participation of the person himself. Scenarios and structural, logical and probabilistic models of managing the quality of human life are given. Special software for quality management is described. The relationship of human quality of life and the digital economy is examined. We consider the role of public opinion in the management of the “bottom” based on the synthesis of many studies on the management of the economics and the state. The bottom management is also feedback from the top management.

To the Editor.— The commentary by Singer1 must not go unchallenged. This member of the American Academy of Pediatrics takes exception to this statement, and he in no way espouses "religious mumbo-jumbo" which Singer applies to his possible opponents. Nor does this writer espouse the application of heroic measures to the preservation of human life under all circumstances. There is such latitude in Singer's discussion that "quality of life" can mean almost anything. I will not belabor the many aspects of Singer's rhetoric but must make two points.

Annotation. The problem of suicide and euthanasia has been particularly updated with the spread of the COVID-19 pandemic, which caused a strong explosion of suicide, because medicine was not ready for it, and the man was too weak in front of its pressure. The article considers the issue of euthanasia and suicide based on philosophical messages from the position of a doctor, which today goes beyond medicine and medical ethics and becomes one of the important aspects of society. Medicine has achieved success in the continuation of human life, but it is unable to ensure the quality of life of those who are forced to continue it. In these circumstances, the admission of suicide or euthanasia pursues the refusal of the subject to achieve an adequate quality of life; an end to suffering for those who find their lives unacceptable. The reasoning that banned suicide: no one should harm or destroy the basic virtues of human nature; deliberate suicide is an attempt to harm a person or destroy human life; no one should kill himself. The criterion may be that suicide should not take place when it is committed at the request of the subject when he devalues his own life. According to supporters of euthanasia, in the conditions of the progress of modern science, many come to the erroneous opinion that medicine can have total control over human life and death. But people have the right to determine the end of their lives while using the achievements of medicine, as well as the right to demand an extension of life with the help of the same medicine. They believe that in the era of a civilized state, the right to die with medical help should be as natural as the right to receive medical care. At the same time, the patient cannot demand death as a solution to the problem, even if all means of relieving him from suffering have been exhausted. In defense of his claims, he turns to the principle of beneficence. The task of medicine is to alleviate the suffering of the patient. But if physician-assisted suicide and active euthanasia become part of health care, theoretical and practical medicine will be deprived of advances in palliative and supportive therapies. Lack of adequate palliative care is a medical, ethical, psychological, and social problem that needs to be addressed before resorting to such radical methods as legalizing euthanasia.

The quality of life depends on water quality. Good water quality and the rational use of water are an absolute need of the new millennium. Although it is an ecological and health priority to prohibit the contamination of water and water protection, it is a responsibility for environmental engineers and chemists to develop and apply effective methods for monitoring and controlling of water quality, and at that way prevent ecological and technological catastrophe on time. In this paper modern methods and process for monitoring, control and detection of cyanide in water and wastewater are presented. Recent developments in instrumental techniques and treatment for determination of this toxic substance in water are described, particularly the methods according to green analytical aspects.

The environment is closely related to nature and its creation. Problems faced by humans related to environmental conditions are things that have a big impact. The influence of the environment is very large on human life which makes the benchmark for good or bad human behavior. Because human life depends on the circumstances around him. Problems are often new things, but the things we often encounter in the environment are a variety of problems, such as the most common environment. According to Tung and Wihardjo (in Ramadhan et al, 2019), problems that occur in the environment caused by careless and intensive human activities in the area where he lives, this is done to improve the quality of life of each. Humans are more selfish without the environment when doing things that damage the environment. Whereas the consequences of their own actions will cause various impacts that are detrimental to themselves and others, such as floods that occur due to waste.

This article presents the study results of the change dynamics in the chemical composition of water in Lake Iskanderkul and the rivers flowing into it, as well as the comparison of water quality in the water bodies of the Iskanderkul Basin and several mid-stream tributaries of the Zarafshan River. It was established that the chemical composition of water in Lake Iskanderkul and its tributaries meets the requirements of the corresponding state standard (GOST 2874-82 “Drinking Water”). However, in terms of dissolved oxygen, copper, zinc, lead and iron the water in Lake Iskanderkul does not satisfy fish farming requirements. The main water pollution sources in the area include such natural phenomena as floods, avalanches, mudslides, and rock dissolution.

This study is only the second to use DNA fingerprinting technology in Maryland to identify fecal coliform sources in order to guide the implementation of water pollution control practices in a watershed with bacterial impairment. By combining the use of digital air photos and GPS with GIS, fieldwork is planned and conducted more efficiently because sample sites can be selected that accurately represent the physical environment of the study area. We can also return to the field and find our sample sites or locate new ones, even in the remotest part of the study area. It is also possible to more accurately map the data directly in the context of its physical environment, greatly increasing the quality of analysis. The integration of DNA fingerprinting techniques with GIS shows great promise for extending our capabilities to identify the controls on water quality and point sources of waterborne health hazards.

This essay offers a reading of “A Most Useful Discussion Concerning Proposals for War against the Turks.” What we have in the “Useful Discussion” is a mock consultation, a literary creation in which Erasmus appears to offer judicious advice on how Christendom might wage a successful war against the Turks, only to undercut the very prospects for such a war by means of various strategies of indirection, hesitation, and ironic reversal. Erasmus works critically and ironically on several levels at once—unsettling the dogmatism of war-mongers, surprising Luther and his critics, frustrating the interests of the powerful, and nudging everyone to think seriously about fundamental questions of human life. Though the “Useful Discussion” may appear to address a specific question about a specific war, it in fact speaks—in its pendular and ironic manner—to more basic questions, inviting readers to reflect with amazement and remorse upon the numbness and deafness of human beings before God; and, on that basis, to work to enhance the moral quality of life.
