오연주,범민준,김동희,백의현,Oh, Yeon-Joo,Beom, Min-Jun,Kim, Dong-Hee,Paik, Eui-Hyun 대한임베디드공학회 2006 대한임베디드공학회논문지 Vol.1 No.2

The home network is generally separated from the Internet, as it is made up of a private network due to security issues and the lack of IPv4 addresses space. Also, a user may want to move from a terminal to another terminal connected in the home network during communicating with people outside the home. In this case, people connected in the Internet, or another home network could not communicate the user at the home. These limitations prevent a SIP-capable device connected in the home network from communicating with another SIP-capable device connected in the Internet or the outside of the home network. To overcome the limitations, This paper proposes the Adaptive SIP Application Server System as a software architecture that a user inside of the home can communicate with people outside of the home when the home is composed of a private IP-based network. Moreover, the proposed architecture provides the session mobility that allows the user to maintain a media session even if changing the terminal inside of the home during the session established. The proposed system was implemented over a home server device which acts functionality as a connection point for transmitting IP packets between a home network and the Internet.

이군희(Gun Hee Lee) 한국경영학회 2006 經營學硏究 Vol.35 No.3

It is difficult to understand and define the home-network industry because the home- network industry has various characteristics stemmed from different industries. The purpose of the study is to define the home-network industry and develop the home-network composite industry index for measuring the current state of home-network industry so that we can look inside of evolution process of home-network industry over years. To identify the home-network industry, we investigate four different sectors - infra sector, solution sector, device sector, and service sector - which are relevant to the home-network industry. For each different sectors, the study develope three index of different aspects ? index related with managerial performance, index related with market, and the index related with future prospect -. Every index score is standardized between 0 and 100 so that 50 indicates average score. After calculation of three different aspect index for each sectors, the final composite index is computed based on the aggregation of four different individual industries. To aggregate the different industry index, the weighted coefficient is utilized based on the market shares of individual industries comparing with the total market size of home-network industry. The final composite index provides 23.5 in 2005. The composite index value is useful if we investigate these values over time. It is interesting to note that the solution and infra industry has high score of both managerial index and market indicator index. On the contrary, the service and solution industry has high score for future prospect index. The implication is that solution and infra industry have major role of the development of home-network industry at present. However, service and device industry have major role for the development of home-network industry for future.The study has several limitations to overcome. Insufficient historical data makes difficulties to understand the relationship between related industries and to make comprehensive framework of measurement model of home-network industry. However the study is the first trial to measure the current state of home-network industry. And more sophisticated measurement model will be expected in further study with sufficient data over long time horizon. The index is useful to understand the evolution process of home-network industry if we investigate the index over several years. The index can be utilized to make strategic decision making for both government and private company as well.

조한진,문성우,김도현,한갑수,박종수,이성우,최성혁,홍윤식 대한응급의학회 2011 대한응급의학회지 Vol.22 No.5

Purpose: Nursing homes continue to increase in number,and more residents are being transferred to emergency departments (EDs). The objective of this study was to investigate the overall characteristics of residents who were transferred to the ED and follow-up their course of treatments. Methods: We identified nursing home residents aged 65years and older who had been transferred to the ED of a regional tertiary university medical center from January 2008 to December 2009. Further attention was paid to those who had been diagnosed with sepsis. Meantime, a separate cohort of sepsis patients was collected, made up of geriatric patients aged 65 years or older who had visited the ED voluntarily from home or through medical institutions other than nursing homes during the same period. We then compared the two cohorts of sepsis patients. Results: A total of 321 patients aged 65 years or older were transferred from nursing homes during the study period. Their mean age was 77.6±7.2 years, and 172 (54.8%)were females. Seventy six (24.2%) patients whose caregivers did not comply with the necessary procedures or refused aggressive management were discharged home or were retransferred to nursing homes. A total of 41 sepsis patients had been transferred from nursing homes, whereas 64 patients had visited the ER voluntarily or through medical institutions other than nursing homes. Even though the difference between the two groups was not significant statistically, patients transferred from nursing homes tended to be discharged or retransferred to nursing homes with inadequate treatment. Conclusion: A considerable number of patients transferred from nursing homes were found to be discharged or retransferred to nursing homes during acute care due to refusal of aggressive treatments. Likewise, the comparison of sepsis patients between the two arms showed a greater portion being retransferred with inadequate treatment as well as a greater rate of mortality among patients transferred from nursing homes.

최승현 ( Choi Seunghyeon ),김정빈 ( Kim Jungbin ) 한국공간디자인학회 2023 한국공간디자인학회논문집 Vol.18 No.8

(연구배경 및 목적) 2020년 정부는 장애인을 위한 안전한 지역사회 환경의 구축과 장애인 그룹홈 시설의 유형 개발을 선언하였다. 매년 꾸준히 증가하고 있는 발달장애인에게 자립과 사회성 함양에 긍정적 영향을 미치는 것으로 알려진 장애인 그룹홈은 탈시설 정책으로 인한 공급 확대를 기대할 수 있겠지만, 장애인 그룹홈을 대상으로 도시공간 중심의 연구는 수행된 바가 없는 실정이다. (연구방법) 장애인 그룹홈이 발달장애인과 주류사회와의 사회통합을 이념으로 삼는 점을 토대로, 사회통합 실천 가능성이 높은 경기도 지역을 연구의 범위로 삼아 연구를 수행하였다. 그리고 장애인 그룹홈의 공간정보 데이터를 구축하여 시설의 공간 중심 유형화 과정을 수행하였다. 이후 거주자의 특성에 대한 이해를 중심으로 유형별 장애인 그룹홈의 공간적 특성을 분석하기 위해 대표 시설을 선정하여 현장방문을 수행하였다. 그리고 종사자 간 인터뷰, 거주자의 특성과 활동 내용을 토대로 유형별 장애인 그룹홈의 내부환경과 지역사회 환경의 공간적 특성을 도출하였다. (결과) 먼저 경기도의 장애인 그룹홈을 중심으로 기초 현황 및 공간정보 데이터를 구축한 결과, 장애인 그룹홈은 경기도의 다양한 입지를 중심으로 운영중인 것으로 확인되었다. 그 중 일반주거지역 내에는 다가구주택, 다세대주택, 아파트 유형의 그룹홈이 주요 주거유형으로 선정되었고, 비주거지역 내에는 단독 주택과 사회복지시설 유형이 주요 주거 유형으로 선정되었다. 유형별 대표 장애인 그룹홈의 내부와 지역사회 환경을 분석한 결과, 장애인 그룹홈의 입지지역은 거주자의 주간 활동의 다양성과 사회 적응훈련 시설 간 접근 방식에 영향을 미치는 것으로 확인되었다. (결론) 첫째, 단독주택과 다가구주택 및 10세대 미만의 다세대주택에 장애인 편의시설이 설치될 수 있도록 제도적 보완이 요구된다. 둘째, 아파트 유형을 제외한 일반주거지역 내 주거유형의 경우 거주자들의 안전한 지역사회 참여활동을 보장할 수 있도록 보차분리가 적용된 보행환경이 요구된다. 셋째, 비주거지역 내 장애인 그룹홈의 거주자들이 지역사회 활동에 참여하고 적응훈련을 수행할 수 있도록 접근성을 갖춘 인프라와 복지서비스의 구축이 요구된다. (Background and Purpose) In 2020, the government declared the establishment of a safe community environment and the development of various types of group-home facilities for the disabled. Group homes for the disabled―known to have a positive effect on fostering independence and sociality for the developmentally disabled―are steadily increasing every year and can be expected to expand supply due to de-facility policies. However, no research has been conducted focusing on urban spaces for disabled group homes. (Method) Based on the fact that group homes for the disabled have an ideology of social integration between the developmentally disabled and mainstream society, this study was conducted in the area of Gyeonggi-do, which is highly likely to practice social integration. By constructing spatial data on group homes for the disabled, a spatially centered categorization process of facilities was performed. Subsequently, to analyze the spatial characteristics of group homes for the disabled by type, focusing on understanding the characteristics of residents, representative facilities were selected and field visits were conducted. Furthermore, based on interviews with workers and the characteristics and activities of residents, the spatial characteristics of the internal and community environments of group homes for the disabled by type were derived. (Results) First, by constructing basic status and spatial information data centered on the group homes for the disabled in Gyeonggi-do, it was confirmed that these group homes operate in various locations in Gyeonggi-do. Among them, group homes with multifamily housing and apartment types were selected as the main types of housing in general residential areas, whereas single-family housing and social welfare facilities were selected as the main types of housing in non-residential areas. By analyzing the internal and community environment of the group homes for the disabled by type, it was confirmed that the location of these group homes affected the diversity of residents’ weekly activities and the approach between social adaptation training facilities. (Conclusion) First, institutional supplementation is required so that convenience facilities for the disabled can be installed in detached, multifamily, and multifamily houses with fewer than 10 households. Second, in the case of housing types in general residential areas, excluding apartments, a walking environment with pedestrian separation is required to ensure safe community participation activities of residents. Third, it is necessary to establish accessible infrastructure and welfare services so that residents of group homes for the disabled in nonresidential areas can participate in community activities and conduct adaptation training.
