청소년이여, 교육포부를 키워라? 이주배경 학생의 학업성취도에 대한 ‘능력주의’ 가설과 ‘기회구조’ 가설 비교

이새롬(Lee, Sae Rom),함승환(Ham, Seung Hwan) 한국교육학회 2021 敎育學硏究 Vol.59 No.1

이 연구는 학생의 교육포부가 학업성취도에 미치는 영향이 학생의 이주배경 여부에 따라 달라지는지 살펴보고자 하였다. 이를 위해 서울과 경기 지역 초등학생 및 중학생 1,450명의 자료를 분석하였다. 분석 결과, 학생의 교육포부 수준이 높을수록 그들의 학업성취도 역시 높은 경향을 확인할 수 있었다. 이는 학생 개인의 포부와 노력을 강조하는 ‘능력주의’ 시각과 일관된 것이다. 그러나 교육포부와 학업성취도 간의 이러한 정적 관계는 비이주배경 학생 집단에 비해 이주배경 학생 집단에서 상대적으로 덜 뚜렷했다. 이러한 결과는 학생이 속한 집단 간 ‘기회구조’의 차이에 주목하는 대안적 관점에 설득력을 더한다. 이주배경 학생의 경우 상대적으로 제한된 기회구조로 인해 개인의 교육포부가 크더라도 그것이 높은 학업성취도로 이어지기 어려울 가능성이 제기된다. 따라서 이주배경 학생의 교육적 취약성을 개선하기 위해서는 기존의 개인 중심적 접근법뿐 아니라 교육생태계 전반에 걸친 종합적이고 연계적인 대책 강구가 요구된다. This paper examines the impact of educational aspirations on academic achievement among students from immigrant backgrounds compared to their native peers. Using data from the Korea Multicultural Education Survey 2017, the academic achievement of 1,450 school children in Seoul and Gyeonggi was analyzed. The result showed a positive association between educational aspirations and academic achievement, supporting the popular ‘meritocratic’ notion of student success. However, this positive association was much weaker for students of immigrant backgrounds, in comparison to their native peers. This pattern was indicative of the uneven ‘opportunity structure’ in which immigrant-background students encounter less opportunities to translate aspirations into achievement. Overall, the findings of the present study suggest that micro-level interventions for immigrant-background minority students need to be complemented by macro-level efforts to reduce systemic exclusions in the educational ecology.

Objectives: Studies on oral health care in North Korea are being pursued in South Korea. However, the covertness of North Korea offers substantial resistance to the access of information from the country, including in the field of oral health care. In this study, we explored North Korea’s oral health care policy and its status in the Kim Jong-Un Era. Methods: We used existing information from Internet searches and also interviewed three health care professionals who had recently contact with North Korea. Results: At present, there are four development policies of oral health care in North Korea: expansion of dental institutions and resource support, strengthening the prevention and treatment of dental diseases, improvement of dental prosthetics, and increasing the responsibility and role of the dental workforce. In addition, there has been an increasing interest in children’s oral health with the development of a few programs. Conclusions: In order to improve overall oral health care, cooperation is required from North Korea in accessing relevant information in the field of children’s oral health, dental prosthetics, and dental materials. For this to occur, there should be a preliminary trust building process between North Korea and South Korea as well as access to information from reliable sources.

이새롬(Sae Rom Lee),강원석(Wonseok Kang) 성신여자대학교 경영연구소 2016 경영관리연구 Vol.9 No.1

본 연구의 목적은 여군 병과 선정 요인 분석과 병과에 대한 이미지 분석을 통해 각 병과에 우수한 인적자원 유입을 위한 이미지 포지셔닝 전략을 제시하는데 있다. 우리는 선행 연구를 통해 선별한 여군들의 병과 선정 요인들 중 8가지의 주 요인을 대상으로 AHP분석의 쌍대비교를 수행했으며, 그 결과 가정생활이 여군의 병과선정 요인들 중 가장 높은 가중치를 갖는 요인임을 알 수 있었다. 또한, 여생도들이 현재 인식하고 있는 병과별 이미지가 선행연구에서 선별된 병과선정요인들에 부합되는지를 분석하기 위해 다차원 척도법을 이용한 유사성 분석 및 속성 평가분석, 속성값 크기비교를 실시하였다. 그 결과 우수한 자원을 모집해야 할 각 병과별 마케팅 차원에서 경쟁관계에 위치해 있는 병과들을 선별할 수 있었으며 각 병과의 속성에 대한 상대적 이미지를 파악하였다. 본 연구는 그동안 일률적인 홍보 및 교육만을 수행해온 병과들에 대해 대상 집단의 특성을 고려한 포지셔닝 전략을 제시한다는데 의의가 있으며 표본의 크기를 확대하고 대상을 다양화했을 때 병과에 대한 집단별 이미지 파악 및 병과별 우수한 인적자원을 획득하기 위한 기반으로 적극 활용될 것으로 기대된다. The purpose of this study is to suggest image positioning strategy for each branch by analyzing branch selection factors for female officers and branch-images. We conduct pairwise comparison of AHP analysis and sort out eight main factors of branch selection reflecting the results of preceding studies for female army officers. As the result, ‘family life’ comes out to be the first priority among the factors. We also conducted similarity analysis, property assessment analysis and property size comparison utilizing multi dimensional-scaling to analyze female cadets’ perception for each branch. The result helps in apprehending several competing branches and understanding relative images depending on attributes of branches. This study is meaningful in that it suggests positioning strategy reflecting the characteristics of relevant groups to branches that have conducted uniform promotion and education until now. Also, it is expected that if the samples were enlarged and the subjects were diversified, this study would be broadly used to seize the image of groups and be utilized as the basis of acquiring outstanding human resources for branches.

이새롬 ( Sae-rom Lee ),이예리 ( Ye-Li Lee ),이상엽 ( Sang-Yeoup Lee ) 대한통합의학회 2021 대한통합의학회지 Vol.9 No.3

Purpose : Recently, there has been a growing social interest in aging well. Consequently, wellness tourism has begun to attract attention. However, no studies on whether wellness tourism has any objective health benefits have been carried out yet. In this study, we assess the health benefits as well as the degree of improvement in health of a wellness tourism program. Methods : The study involved 30 adults over the age of 19 who live in the Gyeongsangnam-do region. Participants were evaluated on health indicator before and after participating in wellness tourism program. Participants took heart rate variability (HRV) test, and LFT, RFT, CBC, FBS HbA1C, and CRP test were conducted before and after the tour. Additionally, a survey was conducted before and after the program, and participant satisfaction was evaluated. Statistical differences in the tests conducted before and after the program were analyzed using a design t-test, a Wilcoxon signed-rank test, and McNemar’s test. Results : The study showed that participants were very satisfied with and had significant health improvements after the wellness tourism program. The program was also found to be beneficial in improving participants' emotions as follows: BDI (p<.001), fatigue recovery (p=.006), stress relief (p=.003), improved quality of life (p<.05), and improved sleep quality (p<.001). Conclusion : Wellness tourism programs are specifically beneficial for improving participants' emotions (depression, anxiety), fatigue, stress levels, quality of life, and sleep. Therefore, they are beneficial to the overall health. Further research in the future by way of a follow-up study on the long-term effects on health after short-term interventions will provide more validation data.
