The social controversy over the government's plan to increase the number of physicians in 2020 has made a medical workforce plan the subject of a political agreement with stakeholders, including people. In the absence of public consensus on the nature of the future health system, an estimation study without an assessment of the current situation would present a conservative result containing the current problems unchanged. Therefore, it is necessary to conceive the future health system before planning its workforce. If the priority policy goal is to suppress the increase in health care expenditure by limiting the number of physicians as at present, it is not necessary to increase the number of physicians. But if we want to improve the quality of health care services, we have to increase the number of physicians to reach the level of advanced countries in the long term, and we also have to bear significant financial requirements, such as a corresponding increase in medical fees.

Objectives: The purpose of this study is to investigate the factors by the spread of coronavirus infection-19 on the different industries, employed, and vulnerable workers, thereafter reviewing literature to make policy recommendations.
Methods: Academic papers, data, and media reports on the socially underprivileged after the spread of coronavirus 19 infection were reviewed. In order to investigate the change of employed persons reported by the National Statistical Office, the change before and after COVID-19 on the employed persons by industry, the change of employed persons by occupation, and the change of employed persons by position were investigated separately.
Results: The working environment of the vulnerable class employees was atrocious to infectious diseases, where the application for industrial accidents was not properly filed. Industrial accidents related to infectious diseases are often treated individually without filing the proper application for the treatment. In further, there was a controversy over whether to apply paid and unpaid leave at the workplace. It is essential to guarantee paid sick leave at the workplace level. In particular, special employment type workers must be benefited with measures for receiving paid sick leave, and a policy proposal to prohibit disadvantages in working conditions such as minimum tenure, guarantee period, salary level, and reinstatement guarantee after paid sick leave must be prepared.
Conclusions: Preparing and promoting fundamental countermeasures for the working environment of the vulnerable should be prioritized, where measures tailored to each type of industry and occupation are prevalent. Above all, with the recognition of the duty of the nation to minimize damage and sacrifices of the vulnerable and workers, countermeasures should be prepared accordingly.

In order to manage health for the vulnerable, it is not a one-time approach, but continuous and detailed health counseling and health services need to be systematically approached. The purpose of this study is to examine the public sector system for health care for the vulnerable in Korea.
Currently, public projects aimed at protecting the right to health of the vulnerable are the visiting health management project and the resident self-governing public service establishment project. The target is the vulnerable group, and the type of visiting project they visit has a common point. The difference is that the visiting health management project is directly managed by the public health center under the Ministry of Health and Welfare, and the resident self-governing public service establishment project is under the Ministry of the Interior and Safety, and the use of computer systems and the affiliation of manpower are different. These commonalities and differences create difficulties in defining tasks and working together.
As a way to solve this problem, the central government needs to present guidelines of the central system for the management system, and local governments need to establish a cooperative system suitable for the community.
