  • The defatted methanol extract of Raphanus sativus Linn. (Cruciferae) seed (MERS) was evaluated for its antisteroidogenic potential in mature female Swiss albino mice. The methanol extract at the doses of 100 and 200 mg/kg body weight significantly elevated the levels of cholesterol and ascorbic acid contents which serve as a precursor for the synthesis of steroid hormones in ovaries. The extract also significantly inhibited glucose-6-phosphate dehydrogenase and ${\Delta}^5-3{\beta}$-hydroxy steroid dehydrogenase, the two key enzymes involved in ovarian steroidogenesis. Hence the extract (MERS) exhibited significant antisteroidogenic activity.

  • The inflow of infectious diseases is increasing due to the expansion of exchanges between countries and climate change. The public concern and anxiety about the increase of the possibility of infectious disease due to the social environment change are increasing greatly.These pandemics are a serious threat to the economy. Hence, multifaceted efforts are required to prevent them from spreading.In many hospitals, it is very important to promptly report infectious diseases, such as the CDC, when infectious diseases occur. In addition, it is difficult to separate general patients and suspected infected patients in these facilities, so there is a high risk of infection spreading within them. The paper presents the improvements of prevention and nonproliferation by researching the occurrence of infectious diseases, the method of separating infected patients, and the methods of preventing infectious diseases based on the audit results of MERS of the Board of Audit and Inspection.

  • Middle East respiratory syndrome coronavirus (MERS-CoV) belongs to the genus Betacoronavirus and causes severe morbidity and mortality in humans especially when infected patients have underlying diseases such as chronic obstructive pulmonary disease (COPD). Previously, we demonstrated that MERS-CoV-encoded ORF8b strongly inhibits MDA5- and RIG-I-mediated induction of the interferon beta (IFN-β) promoter activities. Here, we report that ORF8b seemed to regulate MDA5 or RIG-I differentially as protein levels of MDA5 were significantly down-regulated while those of RIG-I were largely unperturbed. In addition, ORF8b seemed to efficiently suppress phosphorylation of IRF3 at the residues of 386 and 396 in cells transfected with RIG-I while total endogenous levels of IRF3 remained largely unchanged. Furthermore, ORF8b was able to inhibit all forms of RIG-I; full-length, RIG-I-1-734, and RIG-I-1-228, the last of which contains only the CARD domains. Taken together, it is tempting to postulate that ORF8b may interfere with the CARD-CARD interactions between RIG-I and MAVS. Further detailed analysis is required to delineate the mechanisms of how ORF8b inhibits the MDA5/RIG-I receptor signaling pathway.

  • Recently, the hospital infection has emerged as a major concern in the media. In everyday life, but not good if the infection refers to infection with the population living in the hospital. The case with which the equipment is used in a hospital if the person mediating and mediated, patients sometimes with the pathogen causing the disease to their patients. disease in our country for some time, and Mers is finished, large hospitals are taking place is a change in hygiene and operating systems. The Mers is spreading visits and influenced the patient or patient care. And the hygiene to limit the visiting hours for hospital infection prevention and stabilization of the patient. The infection, especially infection among patients and patients but a number of factors, from the emergency room or intensive care unit of frequent hospital contacts between patients with infection and of course, furniture for storing multiple people to use in the ward also become a source of infection. Hospital, another patient is a Cabinet that used to accept the next patient will cause a secondary infection and the role of infectious agents. Therefore, the general public will have a nervousness in the hospital, also medical care needed to avoid the problem occurred. This study examines such issues for the Cabinet of the hospital with a secondary infection is concerned, eco-friendly and hygienic storage furniture and one-off development that will help to improve the hospital environment for research purposes.

  • Purpose: This study aimed to evaluate the workplace response system (WRS) against infectious disasters (IDs) based on the response attitudes and capacity of occupational health nurses (OHNs) who worked during the 2015 Middle East Respiratory Syndrome (MERS) outbreak in South Korea. Methods: Fifty-one participants who had worked as OHNs at the time of the 2015 MERS outbreak were surveyed from November 20 to December 10, 2016. Data were collected using a self-report questionnaire and analyzed using descriptive statistics and McNemaer's test. Results: According to the survey results, the following were lacking in the WRS: a dedicated ID-response team, manuals, related education programs for OHNs, and health education programs for workers. Results also confirmed that workers were vulnerable to new infectious diseases because of the lack of health checkups and support for workers before and after business trips abroad. Among the respondents, 98.0% answered affirmatively that an ID was important for health management in the workplace, but 64.7% answered that it was difficult to manage an ID. The perceived capacity items to respond to IDs ranged from 3.0 points to 3.3 points. This scores were generally high. Conclusion: As the WRS is currently insufficient, it is necessary to develop an adequate WRS to IDs by addressing the identified problems.

  • Purpose: Crisis is inevitable to every organization and therefore, successful crisis management is critical to the organizations' survival and prosperity. With the understanding, this study aims to draw propositions for successful crisis management of hospitals when facing infectious disease outbreak. For the purpose, a case of a small and medium sized hospital's experience of crisis management during 2015 Middle East Respiratory Syndrome outbreak was analyzed. Methodology/Approach: The detailed internal circumstances and experiences of the hospital during the MERS outbreak were identified by in-depth interview as well as the extensive material review, and analyzed under the view of the theories of accident, error, and crisis in relation of organization management Findings: Overall, nine propositions are drawn by the phase of crisis. In pre-crisis phase, for example, 'the hospital preparedness has positive influence on the effective responding to the crisis'. In detection phase, 'the mindfulness of the hospital organizations' as well as the individuals' has positive influence on detecting the crisis signals'. In crisis phase, for example, 'improvising naturally occurs in crisis by the unknown disease, therefore, a component site supervisor coordinating such improvision is important'. Lastly, in post-crisis phase, 'successful crisis responding experience facilitates the positive hospital culture'. Practical implication: From the experience of a small and medium size hospital, it is suggested that proactive system approach oriented by safety is beneficial for effective crisis management.

  • In May 2015, the first case of Middle East Respiratory Syndrome occurred, leaving 186 patients, 38 deaths, and 16,693 quarantine patients. The government has carried out a monitoring of people in contact with the confirmed or suspected patients to prevent the spread of MERS infection. The management staff conducted monitoring of the quarantine subject twice a day during the 14-day period, to check compliance with isolation. However, as the number of people subject to isolation was increased explosively, such issues as the occurrence of residents occurred due to limitations of management personnel. Managers have also admitted that their home quarantine rules have become nominal when they checked the status of quarantine subject by using a call only two or three times a day, and that it is virtually impossible to control when the departees leave without permission. In this paper, home quarantine equipments and their means of authentication are proposed and verified. As a result of the verification, the proposed methods in this paper are expected to be used later as their own authentication method for home quarantine equipments.

  • The presentation of this paper was triggered by the spread of MERS in Korea in the year 2015. The analysis of the present acts related with MERS is necessary in order to cope efficiently with any probable spread of such infectious diseases as MERS in future. The acts that should be analyzed in this paper include 'Medical Service Act' and 'Infectious Disease Control And Prevention Act' (hereafter, IDCAPA). At first the classification of the infectious diseases in IDCAPA should be referred to. The Act does not properly classify them because the scope of concept of each group of the infectious diseases overlaps each other. This overlap should be removed. The present system in IDCAPA is not proper for the efficient notification and reporting of the infectious disease patients. This is so in some viewpoints including the persons obligated to make the notification and reporting, the persons to whom they should notify and report such patients, and the process of notification and reporting. The efficient approach to the information related with the infectious disease is necessary for the rapid prevention of its spread. Cohort isolation and quarantine of the infectious patients and exposed contacts are the strongest and most efficient steps for the prevention of spread of the infectious diseases. One of the great problems related with such steps would be the conflict of powers or attributions, the likelihood of which is inevitable under the present system of IDCAPA. The IDCAPA distributed the power or attribution to take the steps to the three governments including the central government, the metropolitan government and the primary local government. The power should be concentrated in the central government, which could afford financially to compensate for the huge amount of damages caused likely by the steps. The power to take the steps would be actually just a useless thing for its holder without such financial capacity. The remedy for the victims by the fault of spreader should be approached to in the sense of national wealth. The general principle of tort law could not supply the victims with the sufficient remedy because the damages would be likely too huge for the wealth of such spreader to cope with. In future another parliamentary inspection could reveal another problems in the administration by the government of the MERS event in the year 2015. Any problem caused by defect in the legal system of the control and prevention of the infectious diseases should be taken into consideration when the legal system would be reformed in future.

  • A cluster of severe pneumonia of unknown etiology in Wuhan City, Hubei province in China emerged in December 2019. A novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was isolated from lower respiratory tract sample as the causative agent. The current outbreak of infections with SARS-CoV-2 is termed coronavirus disease 2019 (COVID-19) by the World Health Organization (WHO). COVID-19 rapidly spread into at least 114 countries and killed more than 4,000 people by March 11, 2020. WHO officially declared COVID-19 a pandemic on March 11, 2020. There have been 2 novel coronavirus outbreaks in the past 2 decades. The outbreak of severe acute respiratory syndrome (SARS) in 2002-2003 caused by SARS-CoV had a case fatality rate of around 10% (8,098 confirmed cases and 774 deaths), while Middle East respiratory syndrome (MERS) caused by MERS-CoV killed 858 people out of a total 2,499 confirmed cases between 2012 and 2019. The purpose of this review is to summarize known-to-date information about SARS-CoV-2, transmission of SARS-CoV-2, and clinical features of COVID-19.
