잠재프로파일 분석을 통한 중・고등학생의 직업가치 유형 및 영향요인 연구

홍성표(Sungpyo Hong),임한려(Hanryeo Lim) 한국직업교육학회 2024 職業 敎育 硏究 Vol.43 No.1

이 연구의 목적은 국내 중학생 및 고등학생의 직업가치 유형을 파악하고 유형별 영향요인의 특징을 분석하는 데 있었다. 이를 위해 5차년도(2022년) 한국아동・청소년패널조사에 참여한 중학생 및 고등학생의 응답자료를 활용하였다. 결측치를 제외한 표본 규모는 중학생 2,275명, 고등학생 2,205명이었다. 직업가치 유형을 도출하기 위해 잠재프로파일 분석을 실시했으며, 3단계 접근법을 활용하여 유형에 영향을 미치는 선행변인을 탐색하였다. 연구를 통해 도출된 주요 결론은 다음과 같다. 첫째, 중학생과 고등학생의 직업가치 유형은 유사한 패턴을 보였지만, 집단별 표본의 비율과 직업가치별 수준에 차이가 있었다. 중학생에 비해 고등학생의 경우 상대적으로 직업가치 수준의 변화가 적었으며, 전반적으로 직업가치를 높게 인식하는 비율이 증가하는 모습을 보였다. 둘째, 청소년의 직업가치 유형에는 개인, 학교, 가정적 요인이 복합적으로 유의미한 영향을 미쳤다. 셋째, 사회적 기여와 명예로 대표되는 사회적 측면을 중시하는 집단이 확인되었으며, 다양한 주체들과 긍정적인 관계가 해당 집단에 포함될 가능성을 촉진하는 것으로 나타났다. 넷째, 진로교육 경험이 직업가치에 유의미한 영향을 미쳤으며, 청소년의 직업가치 수준을 높일 수 있다. 연구 결과를 바탕으로 한 제언은 다음과 같다. 첫째, 청소년이 자신의 특성 및 환경에 적합한 직업가치를 정확히 인식하고 이와 관련된 진로탐색을 수행할 수 있도록 진로 및 직업교육 개선이 필요하다. 둘째, 청소년의 다양한 주체들과의 관계가 직업가치에 미치는 영향을 심층적으로 분석할 필요가 있다. This study aimed to identify the types of career values among middle and high school students in South Korea and to analyze the characteristics of influencing factors for each type. To achieve this, data from the respondents of the 5th(2022) Korean Children and Youth Panel Survey, were utilized. The sample sizes were 2,275 middle school students and 2,205 high school students. Latent profile analysis was conducted to derive types of career values, and a three-step approach was used to explore antecedent and outcome variables that influence these types. The main conclusions of the research are as follows. First, while the types of career values among middle and high school students showed similar patterns, there were differences in the proportion of the sample by group and the level of career values. Second, personal, school, and familial factors collectively have a significant impact on the types of career values among adolescents. Third, a group that values the social aspects represented by social contribution and honor was identified, and positive relations with various entities were shown to promote the likelihood of inclusion in this group. Based on these findings, the following suggestions are made. Improvements in career and vocational education are needed to allow adolescents to accurately recognize career values suitable for their characteristics and environment, and to conduct related career exploration.

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.

우크라이나전쟁이 한국안보에 주는 시사점

Russian military invaded Ukraine on February 24, 2022. Ukraine applied European Union membership, and many East European countries already joined the EU. Thus, it is natural to join the EU for Ukraine, but Russia tried to stop Ukraine’s moving towards the EU by the invasion. International community, headed by the United Nations, immediately reacted against Russia’s illegal invasion and assisted Ukraine with a lot of military equipment and weapon systems and rescue funds. Russia’s invasion unexpectedly became a protracted war instead of rapid victory. Ukraine military has fought well and defeated Russian army almost all over the frontal lines. Russian military now takes a defensive posture. The lesson of this war for the ROK is as follow: First, the ROK should maintain a liberal democracy that secures basic human rights. Second, the ROK should have reasonably sufficient military power for its national defense. Ukraine failed to defend its nation country due to insufficient defense capability. Without foreign military assistance, Ukraine could not but surrendering already. Thus, the ROK should build a reasonably sufficient defense capability including Kill chain, KAMD and KMPR. Third, Korean-made-defense products are highly evaluated by international community through Ukraine war. Poland already contracted with Korea purchasing 48 FA-50s fighters, 980 K-2 tanks and 648 K-9 Howitzers. And many countries are actively trying to purchase K-defense products. Forth, strategic alliance is crucial for strengthening national security. Ukraine is still fighting well owing to foreign military assistance. Thus, it is very important for the ROK to strengthen the alliances and friendship with foreign countries in peacetime. Finally, the unity of national people is the most important thing for the survival. When the war broke out, President Zellenskii and former president Poroshenko campaigned for patriotic war-fighting against Russian invaders, and it strongly appealed to international community. Thus, many countries joined in supporting Ukraine and provided a lot of military assistance. Owing to this support Ukraine could strongly resist against Russian invasion.
