        This paper proposes a system to detect sleep posture and breathing cycles for preventing sudden death of infants (SIDS) using MEMS sensors. Infant sudden death syndrome is known to be high in children aged 1 to 4 months. Also, infants under the age of one year are unable to keep their bodies steady, so they spend most of their time in bed, which could cause suffocation in the process of turning or turning over. However, since it is not possible to keep an eye on infants 24 hours a day, it is necessary to develop and introduce a system to address these problems. Thus, after childbirth, a system is proposed to prevent sudden death of infants and children who are over 0 years old and can monitor them through smart devices based on NFC (Near Field Communication). In this paper, the body of a wearable device with MEMS sensor in the abdomen of an infant is used to detect breathing cycle by using algorithms that measure posture during sleep without disturbing the infant's sleep. The outputs of MEMS sensors were analyzed to confirm the possibility as a method of sleeping posture and breathing measurement, and the accuracy of sleep posture and breathing signals were measured in order to verify the practicality of the proposed system. In this paper, we used a sleep posture detection algorithm and the result showed with four sleep posture accuracy of 100%. The respiratory rate was analyzed using the respiration cycle detection algorithm, the mean error rate was 1.96% in the upright posture, 2.37% in the lying posture, 36.72% in the lying down posture, 2.06% in the standing posture. Therefore our study has significant implications for detecting sleep posture and breathing cycle using MEMS sensors, suggesting the possibility of being used as a real-time monitoring device for preventing sudden death of infants. 본 논문에서는 MEMS 센서를 이용하여 무구속 측정방법으로 영유아 돌연사(SIDS)방지를 위한 수면자세 및 호흡주기를 검출하는 시스템을 제안한다. 영유아 돌연사증후군은 생후 1~4개월의 유아에게 발생 빈도가 높은 것으로 알려져 있다. 또한, 생후 1년 이내의 유아들은 몸을 가누기가 쉽지 않기 때문에 많은 시간을 누워서 잠을 자며 지내기에 몸을 뒤집거나 뒤척이는 동작을 하는 과정에서 위험(질식 등)할 수 있다. 유아를 24시간 동안 계속 지켜보는 것은 불가능하기에 이러한 문제점을 해결하는 시스템 개발이 필요하다. 따라서 출산 후, 0세 이상 영유아의 상태를 실시간으로 모니터링하여 근거리 통신 기반으로 스마트기기를 통해 모니터링이 가능하도록 하는 영유아 돌연사 방지를 위한 시스템을 제안한다. 본 논문에서는 영유아의 복부에 MEMS 센서를 내장한 착용단말본체를 착용하여 영유아의 수면을 방해하지 않고 수면 중 자세를 측정 하는 알고리즘과 수면 중 복부움직임 횟수를 이용하여 호흡주기를 검출하는 알고리즘을 개발하여 스마트기기로 제공하고자 한다. MEMS 센서의 출력을 분석하여 수면자세 및 호흡 측정 수단으로써의 가능성을 확인하였고, 제안한 시스템의 실용성을 검증하기 위하여 10명 피 실험자를 대상으로 수면자세 및 호흡신호를 측정하여 검출 정확도를 알아보았다. 본 논문에서 제안한 수면자세 검출 알고리즘을 이용하여 똑바로 누워있는 자세, 옆으로 누워있는 자세, 엎드려 누워있는 자세, 서있는 자세를 분석하여 평가한 결과 100%의 검출 정확도를 보였다. 호흡주기 검출 알고리즘을 이용하여 호흡률을 분석한 결과 레퍼런스 장비의 호흡주기와 비교하여 똑바로 누워있는 자세에서 평균 오차율 1.96%, 옆으로 누워있는 자세에서 평균 오차율 2.37%, 엎드려 누워있는 자세에서 평균 오차율 36.72%, 서있는 자세에서 평균 오차율 2.06%의 결과를 보였다. 본 연구는 MEMS 센서를 이용하여 수면자세와 호흡주기를 무구속 방법으로 검출하였다는 면에서 큰 의미를 가지며 영유아 돌연사 방지를 위한 실시간 모니터링 장비로 활용될 수 있는 가능성을 제시하였다.

      • 영등포구 신길 7, 8구역 재개발 단지계획 : 경사지 집합주택의 공유 공간을 중심으로

        신승우 이화여자대학교 과학기술대학원 2003 국내석사

        RANK : 247631

        본 논문은 노후 주거지 재개발 시에 집합주택 단지를 계획하고 디자인을 제안하는 것으로 특히 경사지형을 고려한 주민 공유공간을 중심으로 진행한다. 서울의 자연발생적인 노후 주거지는 대부분 완만한 경사지인데 영등포구 신길 7,8구역이 그 한 예가 된다. 그러나 기존의 주택 재개발 사업은 지형을 고려하기보다는 무리한 성토 및 절토로 대규모 획일적인 단지를 조성하였기 때문에 경사지형이나 평지에 조성된 집합주택의 계획 및 디자인이 거의 차이를 보이지 않고 있다. 때문에 거주환경이나 도시 경관의 측면에서 많은 문제를 낳고 있다. 이 논문은 재개발이란 과거의 것을 없애고 새로운 것을 생산하는 것이 아니라, 과거와 현재 그리고 미래를 이어주는 매개로 이해하고 거주 형태가 단독 주택, 혹은 다가구, 다세대(4층짜리)주택에서 아파트로 변화되었을 때에도 기존 주민 고유의 커뮤니티 문화를 지속하고 시각적, 심리적으로 뿐만 아니라 기능적으로도 소통하며 이웃 인접지역과 조화를 이루는 것을 계획의 필요조건으로 설정하였다. 이와 같은 조건 안에서 재개발의 특성상 기존 거주자들이 재정착한다는 점을 전제하였을 때 대부분 소형평수가 예상되는데 집합주택 단지 계획 시에 부족한 공유 공간을 확보하고 대상지 지형의 변형을 최소화 하며 이용하는 문제를 다루었다. 또한 경사지에 계획되는 중층 집합주택의 공유공간에 관한 연구는 전무한 실정이다. 그래서 이 논문은 특히 경사지 중층집합주택의 주민 커뮤니티 공간 디자인에 집중한다. 이와 같은 배경 안에서 본 연구는 경사지 성격을 고려한 적절한 주거지 환경 개선방향으로서 중, 저층 집합주택형식을 제안하고 조건에 맞는 공유공간을 계획 및 디자인 한다. 연구의 진행과정은 다음과 같다. 첫째, 기존 경사지 주택 재개발 상황을 살펴보고 문제점 인식을 통하여 주택 형태의 변화 필요성을 이해한다. 둘께, 연구 대상지의 현황과 조건을 조사한다. 현황의 특성을 분석하고 물리적, 사회, 문화적 특징에 따라 정리 한다. 셋째, 대상지 골목길 커뮤니티와 거주자 행태 관계를 이해한다. 넷째, 디자인 개념 및 계획 요소를 끌어내고 적용하여 단지 계획 및 디자인 한다. 연구의 결과는 다음과 같다. 경사 주거지 재개발은 site의 잠재성을 최대한 이용하고 지형변화를 최소화하는 환경적인 고려와 기존 거주 문화의 지속가능과 이웃지역과의 조화를 고려해야 한다. 구역 내 주민들의 커뮤니티 공간으로서 접촉하고 교류하는 공간은 골목길이다. 이 골목길은 단순히 통과로서만이 아니라 입체 녹지 공간이자 놀이 및 작업행위가 이루어지는 studio로서의 성격을 갖는다. 골목길은 마을 전체 커뮤니티의 유기체적 구성의 단위이다. 이 개념은 재개발 시, 공유 공간 계획에서 일상 및 비 일상의 이벤트가 벌어지는 하나의 field를 조성하는 모티브가 된다. 주동 단위 공유 공간은 경사지 level 차를 이용하여 base level을 전면부로 확장하고 보행 deck를 두며 deck 하부에 주차 서비스를 계획한다. 때문에 기존 base level 공유 공간의 불리한 점(채광, 통풍)을 극복하고 보행 deck 에서 단지 공유공간과 연결을 용이하게 하여 거주자간에 물리적, 시각적 소통이 이루어지도록 한다. 이러한 경사지에 적합한 집합주택 타입을 제안하고 공유 공간을 개선하기 위해서는 기존의 건축법을 수정하고 경사도 및 향에 따라 적용할 수 있는 기준이 만들어져야 한다. 나아가 현실적으로 경제성 측면에 재개발의 가치기준이 놓여 있는 상황에서 사회적 인식의 전환이 필요하고 때문에 향후 건설비와 공급에 관한 문제에 관해서도 연구되어야 한다. This thesis is to propose the planning and the design of a collective housing block in senior housing redevelopment projects. Its special focus is on planning and design of community public space on sloping site conditions. In Seoul, most of the naturally generated senior housing districts have sloping site conditions. The study site, Shin Gil 7,8 district In Young Deung Po-Gu is not an exception. However, in present housing redevelopment projects the site conditions are not well reflected in its planning and design. Excessive pile and cut of the site with mass reproduction of the blocks hardly create planning and design differences between collective housing built on a sloping site and that built on a flat site. These current situations generate many problems in housing environments and further in urban landscapes. The thesis redefines the concept of 'redevelopment'. Redevelopment is seen not as destruction of the past and construction of the new, but as a medium that link the past, present and the future. This thesis assumes that change to a certain housing typology, be it a single, or multiple housing, will carry on the identity of the local residents' community culture, further complement it visually, psychologically, and functionally, and harmonize with the neighboring precincts. Considering the characteristics of redevelopment that the local residents are relocated within the conditions mentioned above, small size nits are expected. Therefore, this thesis deals with problem of providing generous community space in the housing blocks while preserving the existing topography. Lack of studies about this issue also provides the need of this thesis to concentrate on the design of community space in mid-rise collective housing with sloping site conditions. Under these background, this study, with the purpose of showing the reasonable direction of improvement of housing environment conforming to characteristics of sloping site, proposes a low and midium-rise collective housing as a desirable sloping housing form and proper plan and design way of community space in that condition. Within these circumstances, this thesis proposes mid and low-rise collective housing as the reasonable housing typology that well reflects the sloped site condition. The process of this study is as follows; First, understand the current state of housing redevelopments on sloping sites, then by recognizing its problems understand the need of change in the housing typology. Second, survey the designated study area's environment and its conditions of needs. Third, analyze the features of the environment md classify them according to its physical, social, and cultural characteristics. Finding out the interrelationship between residents and alley activity. Fourth, understand the relationship between alley(pathway) community and resident's activity. Fifth, bring forth the design concept and planning elements and apply them in the design and planning of the housing block. It is possible to establish the design bases throughout the study mentioned above. Then offer a project as a desirable example of the sloping site collective housing with alley(pathway) community concept. The conclusion of the study is as follows: Sloping site housing redevelopment must be a housing projects considering the environmental characteristics of the site and making the best use of potentiality of it. for example, road ,parking service and community. Housing redevelopment with sloping site conditions needs to make best use of the site's potential. It also needs to consider environmental issues such as minimizing the transformation of the topology, continuance of local culture, and harmonization with the neighboring areas. The community space for the residents, the alley, is where the residents contact and communicate with each other. This does more than serving as a circulation. It serves as a three-dimensional green space and a studio, where play and work activities happen. The alley turns into an element of the whole community organization. This concept becomes a motive to create a field, a community space which is planned in redevelopment projects, where daily and special events take place. Utilizing the level difference, the block community space will expand the front facade in the lower level and create a pedestrian deck and a parking space below it. This will therefore improve the problems of the current base level community space. This also activates the link between the pedestrian deck and the community space, which leads to the improvement of physical and visual connection among the residents. In order to propose the optimal collective housing type in sloping site conditions and to improve the community space, current law need to be modified. Also, a standard that could be applied according to its gradient and orientation need to be made. Further, considering that the value of redevelopment lies in its economical aspect, it is necessary to study about cost reduction and industrialization for mass production.

      • 大統領의 施政演說과 豫算配分의 關係

        신승우 高麗大學校 大學院 2004 국내박사

        RANK : 247631

        During the second half of last century, Korea had been developing economically and politically faster than ever. Within this process, the Korean government intervened in various fields of policy directly and indirectly, especially the President, who has influenced the overall national policies with strong power. The Korean president is the chief of the nation and the administrative head, and is therefore an important participant in the process of policy-making and budget distribution. In spite of that fact, it seems there are relatively not many studies conducted regarding specifically how much influence the President wields upon the political decision-making process and prioritization of various policies and budget distribution scheme. The purpose of this study can be regulated through four(4) categories and the analytical methods are as follows. First, the purpose of this study is to analyze how political intentions in budget speech notes of Presidents in successive generations appear in each field of policy. In order to accomplish this research objective, I have divided the policies into five(5) categories according to national purpose or function politics administrative policies, diplomacy and security policies, economic development policies, social development policies, and education and cultural policies- and ascertained what parts, and how much, each former president was interested in national administration, through the analysis of their budget speeches. In this stage, the content analysis was chosen to analyze each sectors political importance and priority as ranked according to the budget speeches of the former presidents. As a result of the content analysis, according to previous national administrations, how much each president's political will reflected on every sector of government was settled objectively. Secondly, I based the purpose of this study on how former presidents' political will show in each field of budget allocation and with what rates and functions. In this stage, I classified estimated general accounting expenditures by functions after 1948, they are 1) defense expenses 2) educational expenses 3) social development 4) economic development 5) general administration 6) local government finance(granted local finance) 7) redemption of debt and so forth(which was exempted from this analysis). Thirdly, the purpose of this study is to investigate the relationship between presidential political will, as suggested through presidential budget speeches, and the budget allocated for each sector. In this stage, I analyzed the connection between government policies and budget apportionment, correlation, and the direction and the intensity of the changes using PDI analysis method, interrelation analysis method, and chronological organization method with vector. Fourthly, this study's purpose is to evaluate the effects of systematic variables and situational variables influencing decisions of policies and budget distribution for each government sector, as adjudicated by each of the former presidents. For this, presidential election, unified government and divided government, to show the power structure between the president and congress, were chosen as systematic variables to impact upon the rate of political administrative policies, diplomacy and security policies, economic development policies, social development policies, education and cultural policies and budget distribution. And for the situational variables, historical events, which are related to domestic and international politics or economical changes, were considered. The result of this study is as follows. First, the purpose of this study was to analyze how political intentions noted in the budget speeches of successive Presidents favored each government sector, and as a result of the content analysis demonstrated that each President's ideology and interest is a key factor in decisions made relating to individual policy, and also the domestic and international or systematic variables influencing this process. Moreover, this study showed the political will of Presidents, as observed through their budget speeches, is closely connected to the proportion of funds allocated to each sector. The research analysis result regarding the relationship between the Presidential budget speech and budget apportionment presented the political will of former Korean presidents, as shown in their budget speeches, is closely connected to national budget distribution, in each division of government, for the last half century. In other words, we can say that the Korean president had been presenting a long-term national development direction as a strategic leader and had been strongly influencing the decisions for policies and budgets according to that direction. Korean former presidents have a common characteristic in considering national security and economic development policies as being the most important issues. Initially, Presidents focused on security and economic development, due to insufficient resources, and as such we had substantial growth economically in 1960's and 1970's. After that time, from the 1980's, government considered divisional equilibrium and sensed the people's desire for democracy, which in turn increased the importance or social development policies, allowing Korea to advance economically and politically for only half a century. Although there were some methods involving the 'trial and error' system according to policy fields, Korean Presidents were valued for their contribution towards national development with proper strategy choices according to the circumstances in each era. Secondly, this study was devised to analyze how former presidents granted the budget for each department, and with a functional budget analysis, the result objectively showed what priority each government had held, and how, with what pattern budget proportionment had changed. It's not easy to judge if the reins of government really had an effective on policies, or simply acted a symbolic token. But we draw a reasonably objective conclusion by analyzing the records about budget expenditures of that time. And we need to analyze the contents of each budget in order to understand the properties and substance about successive presidents' policies. Policies that are executed into effect may be considerably different from that which the government has promised, and may not even be close. Individual President's declaration about a certain policy can be checked more objectively by examining the budget distribution records. Consequently, to grasp the details of former governments we can compare budget allocations of each president's budget speech to recorded budget allocations. This result focused on analysis of how Korean Presidents rated the importance of policies and their accomplishments, and is significant as it is based on the objective information. The result from this attaches political meaning as followings. First, in this study I investigated how former presidents organized the policies and budget and why they made those strategic decisions. I discovered this is related to the ideology and interests of each president and relevant to the quickening of their government proceedings and fluctuations process. Any specific political power has a financial limitation that the era permitted. This research can offer political meaning by providing a standpoint for policies and budget construction to future strategic decision-makers, and also provide a point of view for how they priorities budget allocation for each government sector. Second, this research focused on the study about the connection between the president's political influence regarding policy and budget distribution, and with the result, I could confirm how budgets changed according to the priority the President of each term placed on specific policies and issues. But, also in many cases there was no obvious connection between the policy and the budget. This analysis result has a political significance because it shows the importance of the relationship between policy and budget to policy decision makers. Third, this study has a purpose to analyze the situation factors that influence presidential political will and budget distribution, and the result exhibited that the situations that the presidents recognized and reorganized subjectively influenced policy decisions and the dispersal of governmental funds. The outcome suggests that the world-view and political ideology of the President, who is responsible for making decisions about the nation's future as a strategic leader, redefines the situations in the process of recognition, requires a more balanced world view and standards of conformity. I hope this research to confirm the possibility of objective judgment about how Korean former Presidents' policies and budget reports were for last half century through positive methods, and provide a proper point of view about the importance of organic connection between policy and budget. The analysis of these matters, based on the objective information, is necessary in order to make a sound judgment regarding the intentions and conduct of former presidents and current political leaders, who are involved in the political decision-making process, and for those who may be assigned to this role in the future

        본 연구에서는 음의 프와송비를 가지는 지지체를 제작하고 프와송비에 따른 연골세포의 반응을 조사하였다. PLCL과 PU 를 사용하여 각각 지지체를 제작하였다. 대조군 시편으로 PLCL은 염침출법을 사용하여 지지체를 제작하였고, PU는 60ppi foam을 구입하여 사용하였으며 양의 프와송비를 보였다. 음의 프와송비를 가지는 지지체를 제작하기 위해서 PLCL과 PU 지지체를 유리천이 온도 이상으로 열처리 하여 가소성을 가지는 형태로 만든 다음 일정한 부피비로 압축시키고 냉각시켜서 음의 프와송비를 가지는 지지체를 제작하였다. 음의 프와송비를 가지는 지지체를 실험군 시편으로 설정하였다. 프와송비의 측정은 시편이 0, 0.5, 1.0, 1.5, 2.0, 2.5 의 압축 strain을 받는 시점에서 사진을 촬영하고, 측정된 이미지 데이터를 바탕으로 간접적으로 계산하였다. 세포 성장을 알아보기 위해서 각 지지체에 2.0×105(cells/scaffolds) 농도로 세포를 seeding 하고, 15% 의 압축을 가하여 인큐베이터에서 배양하였다. 세포성장의 분석에는 CCK-8 assay방법을 통하여 분석하였다. PLCL의 경우에는 음의 프와송비를 가지는 지지체가 제작되지는 않았지만 실험군 지지체의 경우 프와송비가 0에 가까운 값을 보였고 대조군 그룹과 통계학적 유의성을 보였다. PU의 경우 음의 프와송비를 가지는 지지체가 제작되었다. 연골세포의 증식에서는 PLCL과 PU모두 대조군 시편보다 실험군 시편에서 증식률이 뛰어난 결과를 보였다. 세포 seeding 후 3 일 까지는 증식률이 음의 프와송비를 가지는 지지체가 우수하였지만, 5일 후의 증식률은 두 그룹모두 큰 차이를 보이지 않았다. 이는 재료가 가지는 물리적 특징인 stress relaxation이 일어나 지지체가 가지는 프와송비의 효과가 감소 또는 사라지게 되고, 이 현상이 연골세포에게 영향을 주지 못하게 되기 때문이라고 사료된다. 결론적으로 음의 프와송비를 가지는 지지체는 연골세포의 성장에 유리한 조건을 제공 할 것으로 기대된다.
