Over the last few decades, the Internet has brought about a myriad of benefits to almost every aspect of our daily lives. However, malware attacks have also widely proliferated, mainly aiming at legitimate network users, resulting in millions of dollars in damages if proper protection and response measures are not settled and enforced. In this context, the paper at hand proposes MalSEIRS, a novel dynamic model, to predict malware distribution in a network based on the SEIRS epidemiological model. As a result, the time-dependent rates of infection, recovery, and loss of immunity enable us to capture the complex dynamism of malware spreading behavior, which is influenced by a variety of external circumstances. In addition, we describe both offensive and defensive techniques, based on the proposed MalSEIRS model, through extensive experimentation, as well as disclosing real-life malware campaigns that can be better understood by using the suggested model.

In the 4.0 era information has been transforming much faster and influencing daily interactions. Based on social recent phenomenon people were not given the interest to utilize these opportunities to look for the truth instead of prioritizing emotions, preferences to justify. This social atmosphere absolutely reduces the essential meaning of the ‘truth’ itself.  The 'truth' and 'untruth' can not be seen. The capability to analyze by the clear mind of intellect as one of the values of being a religious human has been paralyzed. The truth is claimed by like or dislike to something. How religion especially Christianity has its crucial functions as a social institution to reduce the hoax spreading behavior in its congregation will be provided in this paper. This study took palace in the HKBP Church in Bagansiapiapi, Rokan Hilir, Riau, Indonesia using the qualitative approach by taking the data from observation and interviews. The result shows found that religion by its dogma and religious leader comprehensively reduce the hoax spreading behavior in the congregation.Realitas Kemajuan Informasi 4.0 telah memengaruhi kehidupan. Berdasarkan fenomena terkini memperlihatkan bahwa orang-orang tidak lagi mau memberikan perhatian pada kebenaran yang hakiki dari sebuah informasi yang ia terima. Melainkan cenderung mengklaim kebenaran tersebut seturut dengan preferensi subjektif. Atmosfer kehidupan sosial seperti ini mereduksi perbedaan antara suka-tidak suka dan benar-salah menjadi demikian tipis. Alih-alih menjalani proses nalar yang panjang dan melelahkan, masyarakat cenderung tergesa-gesa mengklaim sesuatu yang disukainya sebagai kebenaran, sebaliknya tergesa-gesa menganggap salah atau sesat sesuatu yang dibenci/tidak disukai. Penelitian ini mencoba mengeksplorasi bagaimana agama sebagai pranata, khususnya agama Kristen memainkan peran yang krusial pada fenomena hoax. Penelitian ini dilaksanakan di Jemaat Gereja HKBP Bagansiapiapi ressort Bagansiapiapi, kabupaten Rokan Hilir, provinsi Riau-Indonesia menggunakan metodologi penelitian kualitatif dengan teknik wawancara dan observasi. Temuan memperlihatkan bahwa agama Kristen secara sistematis dan praksis menjalankan perannya sebagai pranata sosial melalui lembaga gereja. Peran tersebut berakar dari doktrin yang menekan prilaku penyebaran hoax. Penelitian juga memperlihatkan pemuka agama andil dalam menekan perilaku penyebar hoax bagi jemaat

Abstract When the core meltdown accident occurs in the nuclear plant, molten corium falls into a coolant pool of the lower plenum. It is considered that the molten corium jet is broken up, cooled, and solidified with fuel-coolant interaction (FCI). However, the coolant pool could be a shallow condition by the leakage and evaporation of the coolant. In this situation, it is considered that the corium jet bottoms and spreads without the jet breakup. From the viewpoint of safety, understanding a jet behavior and estimating a cooling behavior are needed. The purpose of this study is to clarify the mechanism of the liquid jet behavior in a shallow pool as the fundamental process for estimating the cooling behavior in the real machine. In this paper, we discuss the spreading behavior of the liquid jet after bottoming. The jet injection experiment was conducted using test fluids. By using the 3D-LIF method, the 3D visualization of the liquid jet was Successfully implemented. From the visualization result, the following behaviors were seen. After bottoming, the jet spread radially with the liquid film. As the jet spreading behavior, the liquid film was rolled up to the inside, and the vortex was formed. After a certain time, the vortex was broken. Then the flow and the number density of the fragment were changed.
