Purpose: This study aims to establish detailed spatial planning by identifying the needs for a seclusion module for emergency psychiatric patients. Methods: The necessity of medical space with seclusion function was analyzed from spatial, medical, and social perspectives. The needs for a space capable of performing three medical functions: protection, isolation, and treatment, was analyzed. Among various types of mobile medical facilities, seclusion space was considered suitable for utilizing modular construction methods, as it is the most rational method that can satisfy the environmental level of fixed healthcare facilities' space. Therefore, seclusion modules based on modular construction were planned, consisting of two protective units for stabilizing patients with psychiatric illness, one for treatment unit that can accommodate both internal and external treatment, and another one for an infectious disease isolation unit equipped with negative pressure equipment. Implications: This study analyzed the necessary medical functions of the interior space of the mobile stabilization module based on the spatial analysis of existing medical facilities, and proposed alternative spatial configurations according to treatment, seclusion, isolation functions.

부동산 시장 분석에 있어 기본이 되는 정량적 데이터는 부동산 가격 지수이다. OECD와 같은 국제기구에서는 국가별 부동산 가격 지수를 공표하고, 한국부동산원에서는 광역시 단위와 시군구 단위의 지수를 산출한다. 그런데 공간단위를 시군구보다 정교한 동단위, 아파트 단지 단위로 설정하는 경우, 여러 문제점을 맞이하게 된다. 대표적인 문제는 결측치이다. 공간적 범위를 좁힐수록 단위 기간에 따라 거래가 적거나 아예 존재하지 않는 경우가 존재하기에 이 경우에는 지수의 산출이 불가능한 결측치가 발생할 수 있다. 본 연구에서는 지도학습 기반의 머신러닝 기법을 활용하여 특정 범위와 기간에 거래가 존재하지 않아 발생할 수 있는 결측치를 보완하는 기법을 제안한다. 본 모형을 통해 부동산 매매 지수의 실제값이 존재하는 것들의 예측을 통해 그 정확도를 검증하고 결측치가 발생한 것들의 예측도 해 볼 수 있었다.

Recently, violent crimes against the socially disadvantaged have become more frequent and became serious social issues. In addition, compared to the past, the crime methods have become more diverse and intricate, which results in larger damages. For those reasons, the public are increasingly concerned about crimes and it is detrimental to the quality of life in general. Currently, safety in alleys and other residential spaces is protected only by mechanical and managerial functions such as CCTV and police patrol. Safe environment from crimes can be achieved only if there are environmental and spatial plans such as CPTED (Crime Prevention through Environmental Design) principles. The purpose of this study is to propose a direction for spatial planning that can prevent crimes through environmental elements, by researching the spatial planning and current status of alleys and residential spaces from the viewpoint of CPTED. To do so, first, a review checklist was created based on five principles of CPTED and field surveys were conducted on the northern districts of Busan with high crime rates. Second, the problems were analyzed through the field surveys and checklist was classified based on five principles of CPTED to propose improvements for each item. Also, a computer graphic simulation was used to suggest a design proposal. We expect that the application of the basic environmental design principles and guidelines for CPTED will have the effect of creating crime-free and safe spaces in alleys and residential environment.

본 연구는 대구지역을 대상으로 공간적 지형특성에 따라 실제 바람생성에 영향을 미치는 공간지형적 요소별로 바람생성 기능을 평가하였다. 바람생성 기능에 영향을 미치는 공간지형적 요소가 매우 다양하고 상호영향관계에 있기 때문에 기본적으로 공간특성에 대한 정확한 기초자료의 확보가 매우 중요하다. 그러나 본 연구에서는 관련자료 취득의 어려움으로 인하여 신뢰성 있는 자료의 확보가 매우 제한적이었다. 이에 본 연구에서는 이에 대한 대안으로 위성영상자료의 활용을 시도하였으며, 그 결과는 다음과 같다. 먼저 대구지역의 공간지형적 특성상 바람생성 기능이 높은 지역이 많음을 확인할 수 있었다. 이들 지역은 대부분 시외곽지에 분포하고 있으며, 상대적으로 시가화된 지역에서는 바람생성기능이 극히 열악한 것으로 나타나 공간적 불균형이 매우 크다는 것을 확인할 수 있었다. 그리고 이들 지역이 시가화된 지역과의 공간적으로 연계되는 부분에서는 바람생성 기능이 매우 약화되고 영향범위가 축소됨을 알 수 있었다. 결국 시가화된 지역으로 유입되는 바람길의 효과가 감소되는 결과를 초래하고 있는 것으로 나타났다. 또한 본 연구를 통하여 바람길 생성 평가를 위한 공간자료의 구축수단으로 위성자료의 활용가능성을 확인할 수 있었다.

Trajectory planning is vital for autonomous systems like robotics and UAVs, as it determines optimal, safe paths considering physical limitations, environmental factors, and agent interactions. Recent advancements in trajectory planning and future location prediction stem from rapid progress in machine learning and optimization algorithms. In this paper, we proposed a novel framework for Spatial-temporal transformer-based feed-forward neural networks (STTFFNs). From the traffic flow local area point of view, skip-gram model is trained on trajectory data to generate embeddings that capture the high-level features of different trajectories. These embeddings can then be used as input to a transformer-based trajectory planning model, which can generate trajectories for new objects based on the embeddings of similar trajectories in the training data. In the next step, distant regions, we embedded feedforward network is responsible for generating the distant trajectories by taking as input a set of features that represent the object's current state and historical data. One advantage of using feedforward networks for distant trajectory planning is their ability to capture long-term dependencies in the data. In the final step of forecasting for future locations, the encoder and decoder are crucial parts of the proposed technique. Spatial destinations are encoded utilizing location-based social networks(LBSN) based on visiting semantic locations. The model has been specially trained to forecast future locations using precise longitude and latitude values. Following rigorous testing on two real-world datasets, Porto and Manhattan, it was discovered that the model outperformed a prediction accuracy of 8.7% previous state-of-the-art methods.

Ever since the industrial revolution, large cities have become a field of new lifestyle and urbanization, causing climate change and environmental pollution. As a result, countermeasures for revolving these problems is needed. In addition, large cities in the information age have become a space where each nation executes its public policy to express the competitiveness of each city. In this study, countermeasures for the environmental crises caused by urbanization as well as the sustainable spatial designs for the cities are investigated as a new source of urban competitiveness, and the environmental aesthetics for designing public space is considered. The purpose of this study is to suggest a direction for sustainable designs and planning that is applicable to public space. According to the definition of sustainability, the items of the spatial implementation of ecological, economical and social sustainability are categorized. Based on this categorization, the sustainable designs of public space are classified into five types, and a comprehensive analysis of good public spaces from previous literature is conducted. The concepts of design and three elements--public space, sustainability, and their instrumental meanings, are integrated in this study. The significance of this study lies in the actual application of the classification to the planning and design of sustainable public space in cities, rather than being a conceptual classification.

본 연구는 2012년부터 2021년까지 동북아시아 해역에서 발생한 해수고온현상을 Communication, Ocean, and Meteorological Satellite (COMS)/Meteorological Imager sensor (MI)와 GEO-KOMPSAT-2A (GK-2A)/Advanced Meteorological Imager sensor (AMI) 정지궤도 위성 해수면온도 자료를 통해 탐지하였다. 특히 2018년 이후 및 2020년에 해수고온현상의 빈도와 강도가 눈에 띄게 증가하였음을 발견하였다. Optimal Interpolation Sea Surface Temperature (OISST) 자료와 천리안위성 자료를 활용한 T-test 통계적 검증은 해수면 온도가 통계학적으로 유의미하게 상승했다는 것을 확인시켜 주었으며, 이는 기후 변화의 직접적 영향이라는 결론을 뒷받침한다. 이 연구 결과는 해수고온현상의 지속적인 모니터링과 정밀한 분석의 중요성을 강조한다. 복잡한 지형과 다양한 기후 조건을 가진 동북아시아에서 이루어진 연구는 글로벌 기후 변화가 지역 환경에 미치는 영향을 이해하는 데 있어 중요한 통찰을 제공한다.
