Socio-Economic Adaptation of New Immigrant Groups and their Divergence across Large US Metropolitan Areas under Economic Restructuring (미국 대도시지역 산업재구조화에 따른 신이민집단의 사회ㆍ경제적 적응양태의 도시별 다양성에 관한 연구)

  • This study attempts to understand new immigrants' socio-economic adaptation by linking them with the restructuring economies in large US metropolitan areas. Selecting Los Angeles, New York, Chicago, and Atlanta, we examine the industrial distribution of employed Hispanic and Asian immigrant groups with respect to the industrial change experienced between 1980 and 1990, and residential concentration represented by higher location quotients. The findings are that new immigrant groups are employed in overall industrial sectors close to that of total population and their large residential concentrations are displayed near downtown as well as outlying areas. These suggest that new immigrant groups experience different socio-economic adaptation from those generalized in the previous European immigrants, concentrated in manufacturing sector and near downtown area. This study proposes that divergent economic restructuring across metropolitan areas and new immigrants' backgrounds should be considered for better understanding of immigrants' economic adaptation in the current economic restructuring and its spatial manifestation in the US contexts.

  • Recently, the need to prevent or treat cognitive impairment in older adults has been arising. In particular, they tried to diagnose MCI as an early stage of Alzheimer's disease and to delay the progression to dementia through training cognitive function. Most of cognitive function training have been manufactured to game contents which related to several cognitive function, and it needs to be verified quantitatively whether subjects are paying attention to cognitive function training. Thus in this study, we measured and analyzed EEG signals while performing attention training game contents. As an analysis method, we utilized CI, which shows how much they are focusing on, and RI, which shows how stable they are. The result of this study can be seen that all the subjects' CI were increased, which means that the subjects performed game contents with concentration.

  • This study aims to investigate the effects of an 8-week complex attention concentration program on the brain function index and attention concentration in adolescents with ADHD. The subjects of the study were 18 male adolescents from H School located in I City, divided into three groups: 6 participants in the complex attention concentration program group, 6 in the target-related physical activity group, and 6 in the no-treatment control group. Data analysis included calculating means and standard deviations for group comparisons, and two-way (2RM×6RM) ANOVA was conducted to test differences at various measurement points. Post-hoc tests were performed to examine significant interaction effects (p<.05). The results indicated that the integrated attention training program had a more positive effect on brain function sub-indices compared to both the target-related physical activity group and the no-treatment group. Similarly, the program showed a more positive effect on attention levels compared to the other two groups. Based on these results, it can be concluded that the integrated attention training program significantly improves overall brain function in ADHD students and is advantageous due to its ease of participation. It is suggested that this program could be widely used due to these benefits.

  • 국내 의료용 레이저 업체들은 아직까지 국내시장만을 목표로 한 소극적인 투자로 값싼 제품의 조립 생산에서 벗어나지 못하고 있는 실정이어서 대폭적인 인식 변화가 필요하다. 또한 레이저 개발은 광학기술, 고압전기전자기술, 기계기술, 컴퓨터기술 등이 종합적으로 어우러진다는 점을 감안해 관련 기술의 집중육성도 병행돼야 한다.
