Objectives : This study investigates the association between disease behind the Beijing Epidemic of 1232 and fever causing internal damages as mentioned in the Neiwaishang Bianhuolun. Methods : In order to narrow the fever causing diseases in the Neiwaishang Bianhuolun, the retrospective diagnostic method was used in analysis. Disease behind the 1232 Beijing Epidemic and the fever causing internal damages were categorized. Results : Fever causing diseases in the Neiwaishang Bianhuolun could be categorized as infectious disease, inflammatory disease, irritable bowel syndrome, and fever of unknown origin. The Beijing Epidemic was limited in scale with high fatality, of which possible diseases include infectious disease and inflammatory disease with epidemic medium. Fever from internal damage has a mild prognosis, is non-epidemic, and lacks accompanying symptoms such as acute stomachache, even when it happens with external damage. This narrows the possible diseases to IBS and fever of unknown origin. Conclusions : Among internal damage fever cases treated by Li Dongyuan, there were infectious diseases from the 1232 epidemic and inflammatory diseases with mild prognosis.

As over 1000 new cases of HIV/AIDS occur in Korea annually, preventive health programs against HIV/AIDS are urgently needed. Since phylodynamic studies have been suggested as a way to understand how infectious diseases are transmitted and evolve, phylodynamic inferences can be a useful tool for HIV/AIDS research. In particular, phylodynamic models are helpful for dating the origins of an epidemic and estimating its basic reproduction number. Thus, the introduction of phylodynamics would be a highly valuable step towards controlling the HIV/AIDS epidemic in Korea.

An epidemic infectious disease model consists of six compartments viz. Susceptible, Exposed, Infected, Quarantine, Recovered, and Virus with nonlinear saturation incidence rate is proposed to know the viral disease dynamics. There exist two biological equilibrium points for the model system. The system's local and global stability is done through Lyapunov's direct method about equilibrium points. The sensitivity analysis has been performed for the basic reproduction number and equilibrium points through the normalized forward sensitivity index. Sensitivity analysis shows that virus growth and quarantine rates are more sensitive parameters. In support of mathematical conclusions, numerical experimentation has been shown.

Infectious disease emergency hospitals are usually temporarily built during the pneumonia epidemic with higher requirements regarding diagnosis and treatment efficiency, hygiene and safety, and infection control.This study aims to identify how the Building Information Modeling (BIM) + Industrialized Building System (IBS) approach could rapidly deliver an infectious disease hospital and develop site epidemic spreading algorithms. Coronavirus-19 pneumonia construction site spreading algorithm model mind map and block diagram of the construction site epidemic spreading algorithm model were developed. BIM+IBS approach could maximize the repetition of reinforced components and reduce the number of particular components. Huoshenshan Hospital adopted IBS and BIM in the construction, which reduced the workload of on-site operations and avoided later rectification. BIM+IBS integrated information on building materials, building planning, building participants, and construction machinery, and realized construction visualization control and parametric design. The delivery of Huoshenshan Hospital was during the most critical period of the Coronavirus-19 pneumonia epidemic. The development of a construction site epidemic spreading algorithm provided theoretical and numerical support for prevention. The agent-based analysis on hospital evacuation observed "arched" congestion formed at the evacuation exit, indicating behavioral blindness caused by fear in emergencies.

Due to the global epidemic of infectious diseases, it has become important for all industries to respond to the risk of infectious diseases. Ports in each country are also responding to the risk of infectious diseases, but the occurrence of infectious diseases in ports of various countries is causing a lot of damage to the logistics of ports. Korea is in the same situation, and cases of infectious diseases in ports are steadily being announced. Therefore, this paper conducted semi-quantitative Bow-Tie risk assessment by substituting measures to cope with infectious disease risks in Korean ports into actual cases of port infectious diseases in Korea, deriving improvements and suggesting directions. As a result, it was concluded that it was necessary to standardize some of the countermeasures against infectious diseases and develop more countermeasures.

The spatial spread of a disease in an SIRS epidemic model with immunity imparted by subclinical infection on a population has been considered. The incidence rate of infection and the rate of immunization are both of nonlinear type. The dynamics of the infectious disease and its endemicity in local and global sense have been investigated.

Several studies have suggested the possibility of airborne transmission of infectious diseases such as tuberculosis, pandemic influenza. because the number of patients increases explosively, if infectious disease had a high basic reproduction number, pharmaceutical interventions such as vaccination, chemoprophylaxis in the early stage of epidemic. Thus, non-pharmaceutical interventions such as mask-wearing, installing air cleaners, school closure are important to control and prevent the infectious diseases. However, the current technology on the mask, air cleaning, ventilation, and etc., seems to be not originated from the understanding of infection via airborne transmission. It is important to estimate the aerodynamic behavior of saliva droplets by coughing or speaking in order to understand the phenomena of airborne infection. In addition, the prediction of transmission of infectious diseases through the air is critical to prevent or minimize the damage of infection. In this review, we reviewed the recent studies on the airborne infection by focusing on the aerodynamic characteristics of saliva droplets and modeling of airborne transmission.

Objective: This study aims to provide empirical data on epidemic management measures and childcare teacher education in centers. It examines the relationship between infectious disease knowledge, health control knowledge, and self-efficacy in relation to the practice of preventive behaviors among infant and toddler teachers during the COVID-19 pandemic. Methods: The study involved 300 teachers from Seoul and Gyeonggi Province. Data were collected through questionnaires and analyzed using SPSS 23.0. Results: The study found that there is a positive relationship between childcare teachers' knowledge of infectious diseases and their engagement in preventive behavior. Additionally, internal control among the health care factors of childcare teachers also showed a positive relationship. Furthermore, the study revealed that the self-efficacy of childcare teachers is positively associated with their practice of preventive behavior. Overall, infectious disease knowledge, internal control measures, and self-efficacy were all found to have positive relationships with preventive behavior. Conclusion/Implications: This study proposes a new direction for future teacher education by highlighting the effectiveness of psychological factors, specifically health control materials and self-efficacy, in addition to focusing on improving infectious disease knowledge.

Purpose: This study aims to examine how elementary, middle and high school health teachers in Gyeonggi province react to infectious disease like MERS. Methods: This is a descriptive study using a convenience sample of 1,267 school health teachers. Results: When MERS was an epidemic, school health teachers who took the 'leading' role were 92.4%. A school heath teacher's countermeasures against infectious diseases showed a high score during MERS outbreak (3.81) compared to regular days (3.59). Conclusion: Based on such results, it has been determined that schools need to keep two types of procedures manual, such as 'countermeasures on a regular basis' and 'countermeasures in the event of a pandemic disease outbreak' manual in the staff offices so that anyone can view them at any time. It is necessary to prepare regulations to strengthen their authority so that school health teachers can take the role of control tower, in a professional capacity, when communicable disease is spreading. In order to prevent any confusion and chaos, there should be a unitary reporting system at each school when dealing with an epidemic. School health teachers need to get continuous training to reinforce their abilities to react to communicable diseases.
