This chapter will describe the biological nature of viruses belonging to the Coronaviridae family. Coronavirus disease or COVID-19 which, with its ever-expanding attack around the globe has become the topic of discussion of the current era. The disease is caused by a SARS-CoV-2 virus which belongs to the Coronaviridae family. This family of the virus has a history of pandemic significance through its attacks of SARS and MERS since the year 2000. They are known to have affinity towards respiratory tract and any disease that erupts out of their group have caused mild and severe respiratory infections globally. Thus, understanding the virus by learning the characteristics of its familial strain will help us to combat their attack even after mutation in the future. This chapter also discusses the pathogenesis of each virus organism in this family, as well as their clinical characteristics and diagnostics, in order to understand their disease-causing pattern and the efficacy of vaccination in mitigating the worst outcomes of the disease.

One hundred twenty-six consecutive cases of sudden and unexpected death in children between the ages of 10 days and 2 years were studied. Anatomic and microbiologic studies were carried out and an investigation was made at the home in each case. Both sexes were equally vulnerable. Eighty-five per cent of the children were less than 6 months old. The peak incidence was at 2 months. Ninety-nine children were found dead and 27 were observed to die. The same variety and severity of anatomic lesions were found in both categories. Sixteen children in the same age range who died rapidly following known lethal voilence were studied as a control group. Of the nontraumatic sudden death ("unexplained") series 106 (84 per cent) revealed microscopic inflammatory changes in 1 or more sites of the respiratory tract, and histologic evidence of inflammatory disease in other organs was seen in many cases. Acute hemorrhagic pulmonary edema was a common anatomic finding (82 per cent). It was usually accompanied by visceral and cerebral congestion and hemorrhages. Special investigative procedures including staining of the liver for glycogen, determination of the glucose level of the cerebrospinal fluid and study of the adrenals for sudanophilia and birefringence indicated that these factors are without significance in sudden death in early life. A variety of congenital and acquired abnormalities, the presence of which had been unsuspected, was demonstrated at necropsy. Eleven per cent of the 126 cases showed no anatomic abnormalities other than the circulatory phenomena. No single bacterial organism or group of organisms was isolated with any degree of consistency from any site. All attempts to isolate viruses were negative. Ante-mortem symptomatology, circumstances of death, history of contact with infectious disease, and past history of repeated respiratory infection were without prognostic significance and were not pathognomic as to the cause of death. Eighty children had histories of mild illness for 48 hours or less prior to death. Fifty-three children had received some form of treatment during this interval. Sixty-nine children had histories of contact with infectious diseases. Forty-one children had past histories of repeated respiratory infections. The cases came from every social level. Sixty-five per cent had received good care while 35 per cent had received poor care. Many of the control cases showed inflamatory disease in the respiratory tract similar to that seen in the natural death group as well as anatomic evidence of lethal trauma. The inflammatory lesions are thus not incompatible with life. Several hypotheses are offered in an effort to link microscopic inflammatory respiratory tract changes with hemorrhagic pulmonary edema and sudden death. Anatomic and anamnestic evidence exclude mechanical suffocation by bedding. No statement as to the cause of death of an infant who has died suddenly and unexpectedly should be made without complete gross and microscopic studies and thorough investigation of the scene and circumstances of death.

The year 2000 was interpreted by theologians of different currents as "special", "final", as one that should determine the further fate of mankind. The points of view for the period that will follow after him, and accordingly the fate of civilization in the future, were quite pessimistic. They can be classified in the following sequence: civilization has reached the limit of its existence, it will gradually die; The global problems of the present (ecological, social, moral) are a sign of the "end of time". From here two perspectives: believers expect salvation, eternity, paradise, the kingdom of God on earth, and nonbelievers, respectively, eternal suffering, non-being. Therefore, the end of 2000, according to theologians, marks a prehistory, and the next millennium - a true story, the history of a new, God's civilization.

David Magnusson has been the most articulate spokesperson for a holistic, systems approach to personality. This paper considers three concepts relevant to a dynamic systems approach to personality: dynamics, systems, and levels. Some of the history of a dynamic view is traced, leading to an emphasis on the need for stressing the interplay among goals. Concepts such as multidetermination, equipotentiality, and equifinality are shown to be important aspects of a systems approach. Finally, attention is drawn to the question of levels of description, analysis, and explanation in a theory of personality. The importance of the issue is emphasized in relation to recent advances in our understanding of biological processes. Integrating such advances into a theory of personality while avoiding the danger of reductionism is a challenge for the future.

Abstract. In this article, we reflect on 50 years of the journal Social Psychology. We interviewed colleagues who have witnessed the history of the journal. Based on these interviews, we identified three crucial periods in Social Psychology’s history, that are (a) the early development and further professionalization of the journal, (b) the reunification of East and West Germany, and (c) the internationalization of the journal and its transformation from the Zeitschrift für Sozialpsychologie to Social Psychology. We end our reflection with a discussion of changes that occurred during these periods and their implication for the future of our field.

Infeksi saluran pernafasan akut atau yang sering disebut ISPA merupakan infeksi pada saluran pernafasan baik saluran pernafasan atas atau bawah.ISPA juga kebanyakan terjadi pada anak balita karena daya tahan tubuh mereka tidak kuat dalam menghadapi penyakit ISPA. ISPA mengakibatkan kematiansekitar15%-20% per tahun pada usia balita di Negara berkembang. Tujuan penelitian ini adalah untuk mengetahui dan menganalisa peran ibu dalam meningkatkan sistem imun anak dengan ISPA.Metode penelitian yang digunakan dalam penelitian ini adalah kualitatif deskriptif dengan sampel purposive sampling.Populasi dan sampel penelitian ini adalah ibu yang mempunyai anak dengan riwayat dan saat ini menderita penyakit ISPA di Batu Gajah Kota Ambon.Partisipan dalam penelitian ini berjumlah 5 orang. Hasil dari penelitian mendapati 4 kategori yaitu pemberian nutrisi pada anak untuk memenuhi kebutuhan agar sistem imunnya terjaga, kebersihan lingkungan, peran ibu dalam melakukan pencegahan pada anaknya yang mengalami ISPA, dan  peran ibu dalam menjaga dan mempertahankan kesehatan anaknya.   Kata kunci: peran ibu, sistem imun, ispa THE ROLE OF MOTHERS IN INCREASING IMMUNE SYSTEM OF CHILDREN WITH ACUTE RESPIRATORY INFECTION    ABSTRACT Acute respiratory infections or often called ARI is an infection of the upper or lower respiratory tract. ARI occurs mostly in children under the age of five because their endurance is not strong in dealing with ARI. ARI results in deaths of around 15%-20% per year at the age of under-five in developing countries. The purpose of this study was to determine and analyze the role of mothers in improving the immune system of children against ARI. The research method used in this study was qualitative descriptive with a purposive sampling sample. Respondents and samples of this study were five mothers who had children with a history of ARI and currently suffering from the disease in Batu Gajah, Ambon City. The results of the study found 4 categories, namely providing nutrition to children to meet their needs so that their immune systems are maintained, clean environment, mother's role in preventing children with ARI, and mother's role to preserve and maintain the health of their children. The findings indicated that in terms of coping or improving the immune system of a child to avoid ARI, it is necessary to have role the of mothers in providing nutrition so that the immune system is boosted, besides that the mother can prevent and protect her child from various diseases, especially ARI. Keywords: role of mothers, immune system, acute respiratory infections

The article is devoted to the history of reception and interpretation of the ideas of Marx and Engels. The author considers the reasons for divergence between Marxist and neoclassical economic theories. He also analyzes the ways of vulgarization of Marx’s theory and the making of Marxist voluntarism. It is shown that the works of Marx and Engels had a certain potential for their over-simplified interpretations. The article also considers academic ("Western") Marxism and evaluates the prospects of Marxist theory in the future.
