This study investigated various alternatives for childcare among dual-earner families and discussed implications for public policy development. Eight employed married women and two of their husbands were interviewed about work-family balance. All the interviewees complained that taking cue of the children in dual-earner families is a challenge. They resort to all available alternatives because public childcare support is insufficient and inadequate. There were five different types chilcare: extended family network, public and private institutions, paid help (nannies), rearranging work schedules, and training their children to take cue of themselves. However, all these alternatives entail various problems. More and better childcare facilities and programs should be built and after-school programs should be designed. On the other hand, parents should also make more effort to prioritize children's needs in finding a balance between work and family.

본 논문에서는 PDA(Personal Digital Assistants)을 이용하여 보안성 있는 흠 네트워크 가전 단말기 제어 시스템을 개발한다. PDA와 같은 이동 단말기가 발달함에 따라 외부 네트워크에서 흠 네트워크에 접속하여 가전 장비들을 제어하는 연구가 매우 중요하다. 그러나 방화벽만으로 홈 네트워크의 장비를 안전하게 제어하기에는 많은 문제점을 지니고 있다. 본 논문에서는 외부네트워크에서 흠 네트워크로의 안전한 접근 및 제어를 위한 가상 사설망(Virtual Private Network)을 흠 네트워크 제어 시스템에 적용하는 방법을 제시한다. 또한 다양한 흠 네트워크 단말기에 적용 할 수 있고 홈 네트워크간의 호환성을 높이기 위해서 OSGi(Open Service Gateway Initiative)프레임워크를 사용한다.

The purpose of this study was to clarify the space use pattern and the daily living activities of the elderly with dementia in the common space (dining room, day corner) of nursing home in Japan. The subjects were six units of the 2 nursing homes in Tokyo. For this, researcher visited from September 5 to December 5 and collected data by observations of behavior of the elderly with dementia in common space and interviews with staff for the information about basic characteristics of the elderly with dementia and administration and operation of the facilities. The data were analyzed using the frequency and percentage with SPSS 11 program and recorded in the form of behavior map. The results revealed as follows: first, 6 types (self-concentration type, physical environment-interest type, passive others-interest type, staffs-interaction type, other elderly-interaction type, visitors-interaction type) of the daily living activities of the elderly with dementia in common space were founded. Second, the daily living activities of the elderly with dementia in common space tended to focus on self-concentration type and physical environment-interest type. Third, physical environmental characteristics of common space affected space usage pattern of the elderly with dementia. And it was perceived like as living oriented space, social interaction space, facility space, staff oriented space. Conclusively it was suggested to plan dining space as semi-private space, day comer as semi-public space.

최근 통신, 교통, 의료, 산업시설 등에서 수요가 급증하고 있는 임베디드 시스템은 단순한 임베디드 시스템이 아닌 다양한 임베디드 기기의 동작이 통신을 통해 관찰되고 제어되는 Cyber Physical System(CPS)으로 확장되었다. 또한 구글 글래스, 삼성 갤럭시 기어, 소니 스마트 워치 등의 웨어러블 기기를 활용한 사물인터넷(IoT) 기술활용에 대한 관심이 증가하고 있다. 이러한 상황에서 삼성전자의 스마트홈(Smart Home)과 LG전자의 홈챗(Home Chat)이 잇따라 출시되고 있다. 하지만 이러한 서비스들은 스마트폰과 가전기기간에만 통신이 가능하며 그 이외의 단말과는 통신이 불가능하며 모든 정보는 상업용 포털이 운영하는 글로벌 메시징 서버를 통하여 통신이 이루어진다는 단점이 있다. 본 논문에서는 앞서 언급한 단점을 보완하기 위해 단위공간 기반 실내위치인지망 구축하는 구조를 제안한다. 이를 통해 기기들 및 개개인에 대한 정보가 외부로 유출되는 것을 방지하면서 사물인터넷 채팅을 통해 망 내에 존재하는 모든 단말과의 선택적 통신이 가능하다. 또한 좀 더 범용적인 기기 제어가 가능해지고 개인정보의 외부유출 방지가 가능하다.

The purpose of this study is to investigate the influence of children's socia-demographic variables(i.e., gender, birth order, and the amount of time staying in kindergarten) on, leadership, self-regulation and children's peer play behaviors. The participants of this study are 336 children aged between five and seven in four classes in a private kindergarten and eight classes in a private preschool located in the capital region. The results revealed that, girls showed more leadership, self-regulation, and play interaction section than boys: whereas, boys showed higher response in play disruption and the lack of play disconnection. However, birth order, did not have a significant effect on the sub-domain of leadership, self-regulation competence, and peer play behaviors. As for the duration children stay in preschool or in preschool or kindergarten, children who spend half-day showed higher reaction in behavioral self-control and emotional taking abilities than children who stay in the preschool or kindergarten full day. On the other hand, self-esteem of full-time children was higher than half-time children. Children who were emotionally sensitive, knew how to lead their peer group, and those who were sociable and self-regulated presented to be more active in peer-interaction than others. Second, as the result of the correlation analysis reveals, children's leadership, self-regulation competence, peer play behaviors, and play interaction had a meaningful effect on the sub-variations of children's leadership and self-regulation and they showed significant influence upon play disruption and play disconnection. In addition, girls who were not able to manage or to inspect their behavior and had insensitive emotion demonstrated higher tendency to play disconnected.
