트럼프 행정부의 대북정책 전망

홍성표 ( Sungpyo Hong ),정맹석 ( Maengsuk Jung ) 한국군사학회 2016 군사논단 Vol.88 No.-

Mr Donald Trump was elected as the 45th President of the United States of America by general election on November 8, 2016. Trump won the election despite most of the medias` prediction of Clinton`s advantage. During the presidential election campaign, Trump was harshly criticized by the public including the Republicans due to his unpredictable behaviors. However, he overcame all the huddles, and finally won against Clinton. President-elect Trump has named four retired military officers as head of the National Security Council, Defense, Homeland Security and Central Intelligence Agency. All four are hard-liners on foreign and security policy, particularly on counter-proliferation of weapons of mass destruction. Thus, Trump administration`s policy towards North Korea can be predicted in three categories: First, the possibility of operating surgical strikes to demolish WMDs and to end Kim`s regime is highly probable. The second possibility is to make a deal with Pyongyang by providing economic incentives in exchange of the removal of WMDs. Like Libya and Iran cases, it has already been proven as a very useful solution, bringing a significant benefit to both sides avoiding harmful military conflict. Third, following in the footsteps of the Obama administration can be another option for Trump administration. Whenever North Korea made military provocation, the US played a leading role in the UN Security Council for adopting a resolution against their actions.

이스라엘-하마스 전쟁이 한국안보에 주는 시점

홍성표 ( Sungpyo Hong ) 한국군사학회 2023 군사논단 Vol.116 No.-

Palestine armed group, the Hamas, made a surprise attack on Israel on October 7, 2023. They killed some 1,200 Israeli people and took some 240 hostage from Israel. Israeli Prime Minister Benjamin Netanyahu immediately declared a war against the Hamas, and made a merciless counter attack on Gaza Stripe. Some 17,000 Palestinians were killed by Israeli air strikes, and many cities including Gaza City and Khan Younis in Gaza Stripe were devastated. Two months later, Israeli military goal of complete removal of the Hamas on earth are almost fulfilled. Israeli military has attacked all the spots mercilessly no matter where the Hamas were hidden including the hospitals, schools or refugee camps. The Hamas originally could not stand against the Israeli military even though they made a significant success at the surprise attack on October 7. It is because of the lack of airpower. The Hamas does not have airpower while Israel has a superb airpower. The reason why the Hamas broke this war is to grasp the political power in the Palestinians. The Israeli government has recognized the Patah, a rival group of the Hamas, as the representative of Palestine while the Hamas recognized as a terrorist group. This war is very similar to the 1982 Lebanon war. Those days Prime Minister Menachem Begin led the war against the Palestine Liberation Organizations(PLO), and ended it after devastating the PLO. PM Netanyahu has repeatedly declared this war will end after complete demolishment of the Hamas, and he does not care anything for fulfilling this goal. This war gives lots of lessons for the ROK. First of all, the ROK national leaders should learn Israel’s strong leadership for the security of its people. Natanyahu does not care any internal or external pressures, but only care Israeli people’s security.

대학 소재지에 따른 청년의 노동시장 이행 궤적 분석 : 수도권과 지방대학 졸업생의 비교를 중심으로

홍성표(Hong Sungpyo),임한려(Lim Hanryeo) 한국노동연구원 2020 노동정책연구 Vol.20 No.4

이 연구는 청년들의 대학 소재지에 따른 노동시장 이행 궤적을 유형화하고 비교 분석함으로써 청년들의 노동시장에서의 지위 변화를 이해하고 청년고용 촉진을 위한 방향을 제시하는 데 목적이 있다. 청년패널에서 4년제 대학을 졸업한 955명(2007~11년)의 8년(96개월)간 경제활동상태 자료를 활용했으며, 집단중심추세분석과 차이분석을 사용하여 대학 소재지에 따른 이행집단과 특성을 분석하였다. 주요 연구결과는 다음과 같다. 지방대학 졸업생의 노동시장 이행은 수도권 대학 졸업생에 비해 변동성과 불완전성이 높았다. 둘째, 대학 소재지에 관계없이 여성은 노동시장에서 열악한 지위에 위치하고 있었다. 셋째, 계열별 노동시장 이행과정에서 지방대학 인문계열 졸업생의 상용직 진입이 제한적이었다. 넷째, 노동시장 이행과정에서 자격취득 및 진로상담의 유의미한 차이는 확인되지 않았다. 이러한 연구결과를 바탕으로 지방대학 졸업생의 고용시장 진입과 유지를 촉진할 수 있는 제도적 접근 강화, 지역의 노동시장개선과 대학의 연계 촉진, 여성 및 계열별 노동시장 이행을 위한 맞춤형 취업 및 진로지원에 대한 제언을 제시하였다. The purpose of this study was to understand the change in the status of youth in the labor market and to provide implications for facilitating youth employment by categorizing and comparing the trajectory of labor market transition according to the university’s location. Economic status data of 8 years(96 months) of 955 graduates(2007~2011) who graduated from university of youth panel was used to analyze the trajectory of labor market transition. The method of analysis used group-based trajectory analysis and difference analysis. The main research results are as follows. First, the labor market transition of local university graduates was higher in volatility and incompleteness than those in metropolitan areas. Relatively, the proportion of graduates from the metropolitan area entering and maintaining regular jobs was high, and in the long run, the ratio of local university graduates to non-wage labor was high. Second, regardless of where the university was located, women were in poor positions in the labor market. Women were less likely to enter regular jobs than men, or were converted into non-economically active populations or non-wage labor after entring. Third, in the transition of labor market status by majors, entry into regular jobs by graduates of humanities from local universities was limited. Fourth, there was no significant difference between certificate acquisition and career counseling in the process of labor market transition. Based on the results of these studies, the following suggestions were made. Reinforcing institutional approach to promote entry and maintenance of labor market for local university graduates, improving local labor market and facilitating linkage with universities, and customized employment and career support for women and liberal arts students.
