The aim of this paper is to find out different preference of common spaces and shared activities in senior cohousing community between regions in Korea: Seoul and other cities. Social survey was conducted nationwide and the respondents were 50s only, since they are the generation who will face to elderly housing subject within 10 years in turbulent Korean society. Collected data, about 1000, were analyzed by SPSS program using frequency, percentage, and Chi-square test. In summary, respondents mostly would like to move to senior cohousing on circumstance when they remain alone without big difference between regions. Loneliness and housekeeping were considered as the most difficult issues for the elderly to manage by themselves. Among common spaces, exercise room was the most preferred space to meeting room and kitchen. Exercise room was more preferred in Seoul than in other cities, on the contrary meeting room was evidently less preferred in other cities than in Seoul. Regarding shared activities, resident meeting, gardening, and common meal were revealed as less preferred activities than hobby exercise and tea meeting. As a conclusion, I would like to propose that a big common living room is better to be designed for meeting room cum dining and gathering room with flexibility in order to give residents chances to know each other more often. And since common space and shared activity show different preferences by regions, those are to be designed and planned reflecting region's different circumstance.

Critics of height argue that it de-humanizes our cities. Yet a critical mass is a necessity for vibrant city life, and height is a key contributor. If we can overcome the environmental impacts and technicalities of building tall and dense, our cities' streets can thrive and prosper. To make this happen, we must move towards working together to share resources, so we can ensure the continuity of the public realm. We already have the tools to do this; the challenge lies in the coordination of the public and private institutions that govern urban space. District heating and cooling systems; shared logistics spaces; care, responsibility and ownership of the public realm between buildings; seamless connectivity between modes of transport; creative combinations of shelter and seating, and the placement of buildings so that they are not overbearing to the streets around them - these attributes can be found in many places, though rarely all at once. This paper looks at the development of the city and offers Barangaroo South, Sydney, which addresses all these aspects, as a potential template for future city planning.

Purpose: The study was done to develop a shared decision-making scale for end-of-life patients in Korea. Methods: The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 388 adults who lived in one of 3 Korean metropolitan cities: Seoul, Daegu, or Busan. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data. Data collection was done from July to October 2011. Results: Thirty-four items were selected for the final scale, and categorized into 7 factors explaining 61.9% of the total variance. The factors were labeled as sharing information (9 items), constructing system (7 items), explanation as a duty (5 items), autonomy (4 items), capturing time (3 items), participation of family (3 items), and human respect (3 items). The scores for the scale were significantly correlated among shared decision-making scale, terminating life support scale, and dignified dying scale. Cronbach's alpha coefficient for the 34 items was .94. Conclusion: The above findings indicate that the shared decision-making scale has a good validity and reliability when used for end-of-life patients in Korea.

최근 전 세계 많은 도시는 교통량 및 대기오염을 감축하기 위해 공유자전거 시스템을 도입하여 운영하고 있고, 서울시에서도 2015년부터 따릉이 공유자전거 서비스를 제공하고 있다. 공유자전거의 사용이 확산됨에 따라 대여소별로 자전거의 수요는 증가하고 있으나, 제한된 예산 하에서 대여소별로 수요를 관리하기 때문에 운영 및 관리상의 어려움이 존재한다. 현재 자전거 재배치를 통해 대여소별로 수요의 변동을 해결하려고 노력하고 있으나, 불확실한 미래의 사용자 수요를 정확히 예측하는 것이 보다 근본적인 방안이다. 본 연구에서는 통계적 시계열 분석을 통해 서울시 따릉이의 수요를 예측하는 모델을 개발하고, 이를 실제 데이터를 통해 분석하고자 한다. 특히, 전기 사용량의 수요에 사용했던 Holt-Winters방법을 따릉이 수요 예측을 위해 변형하여 적용하였고, 또한 파라미터들의 변동이 실제 수요예측에 어떠한 영향을 미치는지 민감도 분석도 수행하였다.

공유형 전동킥보드의 수요가 날이 갈수록 높아짐에 따라 국내에도 다양한 업체들이 공유형 전동킥보드 대여 서비스를 제공하고 있다. 관련 분야가 급성장함에 따라 사용자들은 주변에서 공유형 전동킥보드를 손쉽게 대여할 수 있게 되었지만 정해진 대여 스테이션이 부재한 이유로 사용 후 관리가 제대로 이루어지지 않고 있고, 대여용 전동킥보드에 대한 무책임한 사용으로 많은 전동킥보드가 훼손되고 있는 상황이다. 이러한 이유로 공유형 전동킥보드에 대한 시민들의 인식이 부정적으로 변하였고, 일부 도시에서는 공유형 전기자전거의 서비스가 제한된다고 한다. 이에 본 논문에서는 무분별한 사용으로 대여 시스템에 부정적 영향을 줄 수 있는 Black Consumer를 추출할 수 있는 사용자 필터링 시스템을 제안한다. 본 시스템이 도입될 경우 안전한 전동킥보드 사용과 관리가 가능할 것으로 기대된다.

After the modern age, the rapid urbanizationhad a big impact on the then architecture. R. Venturi and A. Rossi are two of the leading architects, developing architecture in cities in the US and Europe respectively. This study shed light on a tangible and intangible meaning and interpretation of urban landscapes through their architectural thoughts and architectures. The followings are the physical and intangible meaning and interpretation in architectural thoughts and works of those two architects. Venturi understood that iconological landscapes at the roadside in large citiesare the nature of physical landscapes. To Venturi, the façades of buildings at the roadside are a part of signage such as traffic lights and road signs, and those façades have the meaning of symbolic systems beyond simple physical landscapes. To A. Rossi, types of buildings as physical townscapes are a key role supporting raw data of classification in architecture. And also, those types have significance of the basic data shedding light on the principles and history of cities. For intangible factors in R. Venturi's architecture, daily routine, function and use, time, a use for a building and others form complex architecture. And also, those factors describe shared values of the same period as the façades of buildings and complex symbols and formative lexicons in metaphorical terms. For A. Rossi's intangible factors, 'collective memory' is buried in inhabitants of the city, and with that, the city is a place for memory to its inhabitants. What is more, cities' monuments have intangible landscapes like 'sustainability', 'permanence' and so on. With lots of events happening throughoutcities, those monuments are the whole images of cities giving the value to the urban buildings that reside in cities. Finally, R. Venturi's all-encompassing complex architecture concept was extended on a tangible and intangible point of townscapes. It was found that A. Rossi's tangible thought was formed from the whole landscape of historic cities in then Italy as the background of time and place. Also, With types of urban buildings and 'collective memory', A. Rossi drew architectural norms and formats of unchangeable types.

As shared electric kick scooters spread to cities worldwide as a result of the proliferation of personal mobility, they have emerged as a significant social issue, impacting pedestrian and user safety, as well as urban aesthetics. In this study, we propose solutions to the unique problems associated with shared electric kick scooters, such as illegal parking, charging, and redistribution. Furthermore, we present research on supplementary services utilizing electric kick scooters in urban areas to enhance citizen safety and user satisfaction through the development of an autonomous electric kick scooter system structure and operational strategies. We suggest a low-cost autonomous electric kick scooter structure and propose AI processing, sensor fusion, and system operation methods to add autonomous capabilities to affordable electric kick scooters. Additionally, we propose operational systems and related technologies for offering various supplementary services.

This study aims to propose a smart city governance logic model that can accommodate more diverse information service systems by mixing hub-and-spoke and blockchain technologies as a data management model. Specifically, the research focuses on deriving the logic of an operating system that can work across smart city planning based on the two data governance technologies. The first step of the logic is the generation and collection of information, which is first divided into information that requires information protection and information that can be shared with the public, and the information that requires privacy is blockchainized, and the shared information is integrated and aggregated in a data hub. The next step is the processing and use of the information, which can actively use the blockchain technology, but for the information that can be shared other than the protected information, the governance logic is built in parallel with the hub-and-spoke type. Next is the logic of the distribution stage, where the key is to establish a service contact point between service providers and beneficiaries. Also, This study proposes the establishment of a one-to-one data exchange relationship between information providers, information consumers, and information processors. Finally, in order to expand and promote citizen participation opportunities through a reasonable compensation system in the operation of smart cities, we developed virtual currency as a local currency and designed an open operation logic of local virtual currency that can operate in the compensation dimension of information.

This study explores the significance of AI-driven smart cities and their geopolitical implications, focusing on efficient smart economies, social and environmental connectivity, and sustainability. France is leading in AI development and adoption within Europe, possessing the necessary infrastructure and technology for smart city implementation, yet it must address social inequality and the digital divide. Japan is leveraging AI for smart city development to tackle its aging population, excelling in technology innovation and infrastructure, but it faces challenges in social acceptance and data privacy. Ireland, as a European hub for major IT companies, is well-positioned for AI smart city construction, though it must overcome issues like housing shortages and infrastructure expansion. The Netherlands must address social conflicts and housing shortages caused by high population density and increasing immigration. For successful AI smart city development, it is crucial to integrate immigrants, expand housing, and create economic opportunities. South Korea's major platforms like Naver and Kakao, are poised to play a central role in the AI smart city era, leveraging their vast data analytics capabilities, robust telecommunications infrastructure, and strong user base to enhance global competitiveness.
