South Korea does not plan to compromise on doctors _strike_ South Korean government is ready to fight to the end

However, in other words, we should know more about it. LANA電子煙 The law of development has brought new vitality to the whole industry and revitalized the market.https://www.lanatw.tw

The medical profession in South Korea has been playing a game with the government for more than half a month, the general election is just around the corner, and the doctors’ strike is escalating.

According to Yonhap news agency quoted by the Global Times, 430 professors from Seoul University School of Medicine attended the meeting on the 11th to issue an ultimatum: if the government does not come up with a sincere and reasonable solution to the situation of interns and residents’ collective resignation, all professors will submit their resignations on the 18th. South Korean media commented that the medical front line is likely to fall into greater chaos.

The South Korean government does not intend to compromise, and responded on the 12th, expressing serious concern about this. South Korean President Yoon Yue issued a directive on the 12th, calling for the rapid promotion of health care reform measures, including expanding the enrollment of medical schools, in accordance with the principles.

In addition, the South Korean government has sent license revocation notices to nearly 5000 doctors who refused to return to work, and decided to send 20 military medical officers and 138public health doctors to 20 hospitals from the same day to meet their urgent needs.

With the intensification of aging, the demand for medical resources in Korean society is increasing day by day. The South Korean government announced plans to expand the enrollment of medical students in early February: the enrollment of medical schools in colleges and universities increased from 3058 at this stage to 5058 in the 2025 academic year. According to South Korean health authorities, if the current enrollment scale remains unchanged, there will be a shortfall of 150000 South Korean doctors by 2035.

But the plan to expand enrollment has drawn strong opposition from doctors’ groups and medical students. They believe that the move will lead to excessive health care, strain the funding of the health care system, and lead to a decline in the quality of medical education. Moreover, South Korea lacks the mechanism to regulate the choice of departments for medical graduates, and blindly increases the number of medical students, which will lead to the accumulation of medical resources in big cities. Some medical staff are also worried that the plan to expand enrollment will lead to a reduction in the income of doctors.

Recently, medical professors at a number of South Korean universities are planning to resign collectively. On the 7th of this month, the Emergency response Committee of the Association of professors of Ulsan University Medical College agreed that the professor would submit his resignation on his own. The Association of Professors of Yonsei University School of Medicine set up an emergency response committee on the 12th, and the Association of professors of Cheng Junkuan University School of Medicine held a meeting on the same day. The School of Medicine of Katuli University will meet this week to discuss whether to take collective action.

In response to the possible collective resignation of medical professors, Oval Office officials insisted that since the president demanded rapid progress in accordance with principles, even professors were no exception for collective actions that left the front line of health care in violation of the Medical Law.

As of the 11th, the South Korean government has sent advance notice of administrative sanctions such as revocation of medical licenses to 5556 interns and residents who have left their posts.

Cao Guihong, head of South Korea’s Ministry of Health and Welfare, said at a meeting on the 12th that the decision of the professor’s collective resignation from the Medical College of Seoul University threatened the lives and health of patients, and that the government would do its utmost to maintain the emergency diagnosis and treatment response system and solve the problem of disorder in the medical scene. He called on professors to protect the lives of patients and work with the government to bring outgoing internships and residents back to the medical front line.

On the 12th, the faculty of Seoul University School of Medicine proposed a compromise. They held a press conference in the Korean National Assembly, saying that both the government and the Korean Physicians Association should abandon their inherent position and entrust overseas authorities and institutions recognized by all parties to analyze South Korea’s health and medical indexes. and according to the results of the analysis to decide whether to increase the number of medical school enrollment, at the same time to build a dialogue mechanism with the participation of the government, medical association, government and opposition, national representatives, professors, internships and residents. Formulate practical basic medical, community and public health policies in the coming year.

However, according to Yonhap news agency, an official from the South Korean President’s Office confirmed on the 12th that the plan to expand the enrollment of medical schools by 2000 students a year will not be adjusted. This figure is scientific, and the government’s determination to promote health care reform has not changed.

Less than a month before South Korea’s parliamentary election on April 10, South Korea’s ruling party has regained a lot of support for its policy of expanding enrollment in medical schools. The results of an opinion poll released by Gallup in South Korea on March 8 showed that the good rate of President Yoon Yue’s administration performance was 39%, and the bad rate was 54%. As for the reasons for praise, the answer to the expansion of medical school enrollment accounted for the largest proportion, accounting for 28%, followed by prompt decision, courage and perseverance (9%). According to an opinion poll released by the agency on February 23, Yin Yue’s good evaluation rate was 34%, and the poor evaluation rate was 58%.

For this protracted standoff, some Japanese media commented that the demand for reconciliation in South Korea is growing day by day. Doctors and the government should not be in the boxing ring. People’s patience is disappearing. We must find a way out of this quagmire through dialogue.

The presidential palace announcement called on all mainstream parties to work together to establish alliances to end the transition period as soon as possible. In an open letter, Macron had previously called for mainstream parties to engage in dialogue and said he would appoint a new prime minister based on mainstream consensus.

On the 7th of this month, France held the second round of voting in the National Assembly election. According to French political tradition, after the National Assembly election, the Prime Minister will submit his resignation to the President regardless of the election outcome. On the 8th, Atar submitted his resignation to Macron, but was asked to stay in office temporarily to ensure national stability.

France’s new National Assembly is scheduled to hold its first plenary session on the 18th of this month and will elect a new speaker. After Attar’s resignation is approved, members of the elected members of Attar’s government can concurrently serve in the National Assembly. Attar himself was also elected to parliament.
