There has been no studies that compare services of residential care centers, group homes, and foster homes although out-of-home care services differ from each other depending on the types of out-of-home care. This study compared care satisfaction of 481 children in residential care centers, group homes, and foster homes for five years. Futhermore, factors that predict care satisfaction of the children were identified using multi-level modeling analyses. As results, this study found that care satisfaction of children in group homes was the higher than that in foster homes and residential care centers. In addition, self-esteem, social support, and types of out-of-home services were identified as significant predictors of changes in care satisfaction. Based on the study results, suggestions to help children adapt to out-of-home care and improve out-of-home care satisfaction were made.

The purpose of this study was to examine the abuse experience of adolescents in out-of-home care on their psychosocial adjustment and the mediating effects of self-regulation skills. A survey was conducted on the adolescents who resided in the city of Busan and received out-of-home care service. The findings of the study were as follows: First, abuse experience was found to have exerted a negative influence on self-regulation skills. Second, abuse experience was found to have exerted a negative influence on psychosocial adjustment. Third, self-regulation skills were found to have exercised a positive influence on psychosocial adjustment. Fourth, self-regulation skills were found to have had a mediating effect on the relationship between abuse experience and psychosocial adjustment. The findings of this study were of significance in that neglect and emotional abuse should be prevented to promote the psychosocial adjustment of teenagers with abuse experience who are in out-of-home care, and in that the importance of the intervention of counseling programs which could foster the self-regulation skills of adolescents was urged.

Drawing on social and cultural capital theory, the study investigates the influences of social capital and cultural capital on the academic achievement of children in out-of-home care. We collected data from 494 children living in out-of-home services, including institutional care facilities, foster care homes, and group homes. To analyze the collected data, a multiple regression analysis method was used. In addition, the IV (instrumental-variables) estimation was utilized to rule out the possibility of reverse causality. The level of children's social capital was measured through children's relationships with parents and friends, parental monitoring, etc. The level of children's cultural capital was measured by their cultural activities, such as going to museums, and playing musical instruments. Children's personal characteristics and placement history in out-of-home services were used as control variables. We found that among personal characteristic variables, self-esteem, depression and anxiety, and delinquency affected the academic achievement of the children. Cultural capital, but not social capital, positively affected the level of academic achievement of the children. Based on the study results, implications for child welfare practice were discussed.

As an introduction of an open spectrum allocation approach with technology and service neutrality is expected as a way to solve problems of frequency shortage due to the expansion of demand for wireless multimedia communications, recently, the new management model of interferences and its standard setting are required. In this paper, as a model for this new interference management considering several candidates, Block Edge Mask(BEM) approach is chosen as the most appropriate model. And to investigate the effects of interference resulting from the standard setting of BEM, assuming the use of LTE systems in the Digital Dividend, BEM out-of-band baseline in the boundaries between digital terrestrial television (DTV) service and LTE mobile communications services which are heterogeneous systems for analysis is derived and the effect of setting guard band is analyzed.

We usually expect that children in residential care are not able to have excellent academic achievement, even though their school achievement in adolescence is crucial as a part of whole lifespan development. The purpose of this study is to carefully understand characteristics and experiences of only a few academically talented children in residential care and to find out the practical suggestion to support the academic performance of children in residential care. For this purpose, we had interviewed eight children in depth and analyzed the data using a qualitative case study method. As a result, we found a total of 21 subcategories and 5 categories. The categories included that 'always being faithful despite being not fast', 'believing myself when I face limitations', 'conflict in high support and high expectation', 'sometimes refusing to support on me, but I am leaning on my mind', 'relieving anxiety by studying'. In conclusion, we found that the central theme of 'running to change prejudice into hope' were found through the cases with excellent academic achievement. Based on the results, we suggested the guidelines to consider when developing and providing the academic support services for children in residential care.

2013년 12월 2일에 아마존의 제프 베조스가 드론을 통하여 30분 배송을 실현하겠다고 배송 테스트를 했다. 고객이 주문한 물건을 플라스틱 보호 박스에 잘 담아 드론에 싣고 고객의 마당에 떨구고 돌아오는 모습을 담았다. 미국의 모든 언론은 드론에 대하여 대서특필하였고, 30분 배송의 실현 가능성에 대한 논쟁을 벌였다. 그 해 연말, 아마존은 쇼핑특수를 누렸다. 돈 안들이고 광고를 독특하게 한 셈이다. 나는 개인적으로 아마존의 드론 배달을 '쇼'라고 생각했다. 고객들의 주거 형태, 드론 비행의 법적인 문제, 드론으로 발생되는 사고, 사람들의 인식 등등 문제가 산적해 있기 때문이다. 그런데 2015년 초부터 알리바바는 1시간 내 차(Tea) 배달 서비스를 상하이와 광저우에서 테스트 중이라고 한다. 또한, DHL이 바다를 건너 섬으로 의약품을 수송하는 시연을 했다. CES 2015에서는 드론 전용관을 만들어 많은 사람들과 언론의 주목을 받았다. 마치 꿈과 같던 것이 실현되는 느낌이었다. 드론을 띄울 수 있는 권리 외에도 드론을 떨어뜨릴 권리도 논의되고 있다. 일본 총리관저에 드론이 떨어지기도 했다. 미국에서는 소형 드론에 폭발물을 탑재하여 타격하는 영상을 보이기도 했다. 개인적인 프라이버시가 존중되어야 할 가정집 위로 카메라가 달린 드론이 날아다니기도 하며, 재소자들의 수감시설에 마약과 담배를 실어 나르다 적발되기도 하였다. 부작용도 만만치 않다는 이야기이다. 나는 학생들에게 100만 원이 넘는 드론을 구매하여 주었더니, 동력인 배터리가 20분밖에 안 된다고 투덜거린다. 영상에 그리고 비행에 소리가 너무 난다고 또 투덜거린다. 바람에 밀려 조정이 어렵다고 또한 투덜투덜하더니만, 결국은 비행 중 조절이 안 되고 떨어져서 결국 박살이 났다. 내구성이 약하다는 이야기는 곧 전반적으로 아직 한계가 있으며 개선할 점이 많다는 의미이다. 위와 같은 부정적인 요인에도 불구하고 드론은 새로운 서비스의 융합으로 신시장이 기대되는 만큼 많은 국가와 기업들이 주목하고 있다. 미국가전협회(CEA)는 2015년 세계 드론 시장이 2014년보다 무려 55% 성장한 1억 3,000만 달러의 규모로 성장하고 5년 뒤에는 10억 달러까지 증가할 것으로 전망하면서 드론 산업의 가능성을 높게 평가하기도 했다.
