"Pneumonia pneumokokus merupakan jenis community-acquired pneumonia yang merupakan infeksi saluran pernapasan akut yang disebabkan oleh bakteri Streptococcus pneumoniae. Dalam penelitian ini, model matematis penyebaran Pneumonia pneumokokus dibangun dengan mempertimbangkan intervensi vaksinasi dan perawatan di rumah sakit. Model tersebut dibentuk dengan membagi populasi manusia berdasarkan status kesehatannya. Beberapa faktor dipertimbangkan dalam mengonstruksi model, seperti individu tanpa gejala, fase laten selama infeksi, dan intervensi vaksinasi dan perawatan di rumah sakit. Studi analitik dilakukan untuk menemukan dan menganalisis eksistensi dan stabilitas lokal dari titik-titik keseimbangan, menentukan bilangan reproduksi dasar (R0), dan menyelidiki jenis bifurkasi model. Ditemukan bahwa model yang dikonstruksi mengalami bifurkasi maju ketika R0=1. Hasil ini menunjukkan bahwa R0 perlu dikurangi sebesar mungkin dengan vaksinasi dan/atau perawatan di rumah sakit untuk menghindari terjadinya infeksi di masyarakat. Beberapa pendekatan numerik ditampilkan untuk melihat visualisasi hasil dari model. Hasil simulasi menunjukkan bahwa laju vaksinasi dan laju perawatan hanya memberikan efek yang sangat signifikan di awal dalam menurunkan nilai R0, tetapi tidak begitu signifikan saat nilai kedua laju yang diberikan sudah cukup besar. Didapatkan kesimpulan juga bahwa peningkatan laju vaksinasi lebih berhasil menekan angka manusia terinfeksi Pneumonia pneumokokus dibandingkan dengan peningkatan laju perawatan. Jenis vaksin yang digunakan dalam proses vaksinasi juga berpengaruh besar dalam menurunkan nilai R0.

Pneumococcal pneumonia is a type of community-acquired pneumonia which is an acute respiratory infection caused by Streptococcus pneumoniae bacteria. In this study, a mathematical model on the spread of Pneumococcal pneumonia is constructed by considering vaccination and hospital care interventions. The model is formed by dividing the human population based on their health status. We consider several things in the model’s construction, such as asymptomatic individuals, the latent phase during infection, and interventions of vaccination and hospitalization. Analytical studies are carried out to find and analyze the existence and local stability of the equilibrium points, determining the basic reproduction number (R0) and investigate the type of bifurcation of the model. We find that the model exhibits a forward bifurcation when R0=1. Several numerical experiments are shown to see the visualization of the model. The simulation results show that the rate of vaccination and the rate of hospitalization only have a very significant effect at the beginning in reducing the value of R0. It is also concluded that an increase in the rate of vaccination is more successful in reducing the number of individuals infected with Pneumococcal pneumonia compared to an increase in the rate of hospitalization.

"So we have seen that the Breton Lay of 'Sir Orfeo' follows the conventions of medieval courtly-love poetry, except for one feuture,nwnely that hero and heroine are husband and wife. lhi s, however , i. s not an Innovation of the noet's;it was taken from the classical version of the story.Aa a story 'Sir Orfeo' is well told,although I suggest that the churacters,by virtue of the reasons postulated on pages 25 and 2o,ure flat.In the F'rankli n' a Tule,Chuucer has also used the earlier,he uses them in a different way.As a story the Franklin's Wale is also good,and in its plot,as has al-ready been ahown,each event has a cause;the characters especially that of Dorigene,can he said to he round; the supernatural element,?nagic,i.s explained in detail. The explanation might not be a scientific one,but at least it is explained, whereas in 'Sir Orfeo' it is not. The courtly-love conventions too are used to servo a certain purpose,nwnely to illustrate Chats cer's views about marriage relationships..."
