드론(drone)이라 불리는 무인항공기(UAV)가 무인전투기, 무인정찰기 등 군사용도를 벗어나 일상생활의 다양한 영역에서 그 쓰임새를 빠르게 찾아가고 있다. 미국 아마존과 구글, 독일 DHL, 중국 알리바바 등이 배달전용 드론을 시범 운영하고 있다. 미국 미네소타 주에 위치한 메이요(Mayo) 병원은 주변 소재 작은 병원에 수혈용 피를 운반하는데 드론을 이용하고 있다. 미국의 경우 수혈용 피 대부분이 대형 병원에 비축되어 있다. 지역의 작은 병원의 경우 1-2명의 환자를 위한 응급 피를 보관하고 있을 뿐이다. 이런 상황에서 혈액 배달 드론은 유용하게 기능할 수 있다. 그렇다고 벌떼처럼 드론이 도심을 떠다니는 일은 당분간 없을 것이다. 미국의 경우 드론사업과 관련하여 현재까지 매우 엄격한 '사전허가'가 요구된다. 그 누구도 하늘을 떠다니는 드론이 폭풍과 같은 기상 이변을 만나 자신의 머리 위로 또는 주택 위로 떨어지는 것을 원치 않기 때문이다.

It needs to be developed for more various ones which considered in the way of their economic and physical conditions. This case study was aimed to supply (or a basic data for developing a housing for tow income elderly through the analysis of elderly housing of Melbourne in Australia. This study evaluated two types of government housing and five types of community housing available to elderly People on low income allowing them to live independently. Results of the research were as follows. 1) High rise apartment living was differentiated from other housing types. Such accommodation had drawbacks, for example it made the elderly difficult to get along with neighbours. 2) Community housing had more various types of housing than government housing and was aimed at encouraging community interaction between residents. Some community housing residents joined the management of the housing committee. As a result, it made the elderly very confident and promoted a good relationship between them and young generations. 3) The strength of community housing was that the elderly could choose the place to live within the community which was familiar to them. 4) The managers in broth government housing and community housing had many roles as adviser and mediator for residents as well as managing the complex. 5) A policy of housing for low income elderly is changing now from management by government appointees to one governed by the community 6) Most elderly prefer to live close to facilities such as medical and shopping centers and convenient transportation and wished to remain in their familiar community as long as possible.

Recently, "aging in place" has become the principle philosophy of elderly housing policy in many countries. However, since there is ambiguity surrounding the universal definition of it, the meaning of AIP has been defined by political expediency. This study aims to discuss the meaning of AIP by examining the transition of elderly housing issues and policy in Japan. During the last two decades, the Japanese government has tried to launch a new elderly welfare system to shift the responsibility of elderly care from the family to the society and from the society to the region. And the focus of elderly housing policy has shifted from the promotion of three-generation dwellings to supporting the development of private residences. However, since the main goal has been limiting the welfare budgets rather than enhancing the quality of life, elderly housing issues have been reduced to a matter of choosing either elderly care facilities frequently located in suburbs or not. This paper suggest that we should pursue the true AIP idea in housing policy, and argues that to do so we need to consider AIP from diverse aspects such as temporal continuity, the range of space, the dynamics of place experience and the capability of communities.

현재 세계적으로, 홍수를 비롯한 자연재해로 인한 피해가 증가하고 있다. 우리나라의 경우, 매년 여름철에 발생하고 있는 장마로 인해 지역 곳곳에 침수피해가 심각해지고 있으며, 이에 대한 피해액 또한 증가하고 있는 실정이다. 또한, 여러 재해의 피해반복과 새롭게 반복되는 건축물 설계로 인해 지형이 바뀌고 있으며, 이로 인해, 기존의 실시된 홍수취약성 분석결과가 현실적으로 반영이 되기 힘든 상태이다. 피해를 줄이기 위해서는 변형된 환경에 맞춰 새로운 홍수취약성 분석을 실시하여 지역의 우선순위를 파악하여야 한다. 본 연구에서는 우리나라중 인구와 건물밀집도가 가장 높은 서울시 25개 구를 대상지역으로 선정하였으며, 인자들을 Pessure-State-Response (PSR) 구조로 나누었다. 압력지수(PI) 에는 유역면적, 주택 수 등 9개의 인자로, 상태지수(SI)는 연 홍수 피해액 등 4개의 인자로 선정하였으며, 대책지수(RI)의 경우에는 재정자립도, 홍수복구금액등 7개의 인자로 나누었다. 분석방법으로는 의사결정과정에서 발생할 수 있는 불확실성을 정량적으로 반영한 AHP방법과 AHP방법에 Fuzzy이론을 결합한 Fuzzy AHP 방법을 통해 각각의 결과를 비교분석하였다. 그 결과, 3개의 지수 모두 인자들의 지역별 취약순위가 바뀌었다. 본 연구의 결과를 바탕으로 홍수 방재 관련 정책 수립 등의 사업 등을 실시할 경우 해당지역에 대한 우선순위를 판단하는데 도움이 될 것으로 판단된다.

대도시의 대기질은 1960년대 이후 지속되어온 국토개발과 성장위주의 경제모델이 각 도시 지형적 특성을 고려하지 못한 채 일률적으로 적용되면서 점차 심화되어 가고 있는 실정이다. 특히 1990년대 이후 연료정책 등 가시적인 효과를 거두고 있는 황산화물(SOx)도 도시권의 일부 지역에서는 인구유입에 따른 주택건설, 산업시설과 교통시설의 확충 등으로 절대량에 있어서 점차 증가추세를 나타내고 있다. 이러한 대도시에서의 대기질 현상을 규명할 수 있는 가장 객관적인 방법은 자동측정망의 활용이라 할 수 있으나, 수도권을 제외한 대도시에서의 대기측정망 수는 운영비용, 지역면적 및 인구밀도 등을 고려 할 때 현실적으로 부족한 실정이다.

They are also confirmed factors that affect a rise of used-housing price in other studies. Third, brand value of apartments affects new housing prices. For example, if the major construction companies build the new apartment, it shows a rising trend than any other housing. Therefore, the local construction companies are expected to be put on a disadvantage places than major construction companies. Fourth, the lotting prices are the most important cause that lead to rise the new housing prices.

The purpose of this study is to improve the private utilization of military welfare facilities that are aging or underutilized in urban areas. It also aims to develop ways to strengthen cooperative win-win strategies between the military and local communities. The use of military welfare facilities by the private sector refers to activities where the private sector generates additional benefits or added value by allowing the use of these facilities, including both private use and improvements to facilities or development of land through private sector involvement. From the perspective of the city and the locals, military welfare facilities are perceived as resident-friendly and excellent urban resources that can promote reciprocal satisfaction between the military and local communities. From the perspective of the military, military welfare facilities are important for enhancing the welfare of military personnel. However, they often face limitations in providing various welfare services due to the aging of facilities and limited operations with a single purpose. The improvement of private utilization of military welfare facilities will bring diverse reciprocal benefits to the military, the city, and the locals. Above all, improving the private utilization of military welfare facilities can help the military and local communities jointly address diverse urban issues. To establish cooperative governance and find flexible and diverse development strategies that can promote the welfare of the military and enhance the quality of life for the locals, it is important that both the military and local communities make continuous efforts.

There have been a growing number of studies that show huge discrepancies between individuals' perceptions of relative economic position and the economic position based on the reported income in the survey. If this is the case, it is expected that the impact of perceived income status on individual happiness can be different from that of objective income status based on the reported income. The aim of this study is to investigate the factors affecting the discrepancies between perception and reality with respect to relative income status, focusing on the 'Reference group theory'. This study also tries to extend existing knowledge of the relative status on the happiness level of individuals, by examining how individual's happiness can be changed by providing the accurate information about their objective income level. There are systematic biases in perceived income status. A majority of people who actually rank in the lower part of income ladder place themselves in higher positions, while a significant portion of rich individuals underestimate their actual income status. Secondly, the misperception about the income distribution is affected by a variety of individual, household characteristics and reference group income. Thirdly, providing individuals with accurate information has a considerable effect on their happiness level.

Investors should understand and actively consider factors like location, future value, policies, pricing, market trends, and their income, as these elements can shift with changing local, social, economic, and policy environments. This study seeks to clarify the impact of investment factors on the performance and reinvestment intentions of Sejong City investors by surveying those who have invested in real estate. This study employs a structural equation model with confirmatory factor analysis, focusing on four aspects: value, economic and policy, psychological, and financial. We find that the investment value factor has the largest impact on investment performance, indicating that investors prioritize the investment value of real estate in Sejong City. In addition, factors increasing asset value and expected satisfaction were significant, indicating that real estate investment in Sejong City yields high returns and investor satisfaction. with a positive outlook for future reinvestment.
