The purpose of this study is to suggest the possibility of scenario for the space analysis in Genius Loci. Genius Loci was designed by Japanese architect Ando Tadao. For this study the theory of scenario which is based on the three-act structure was reviewed in order to understand the characteristics of Genius Loci spaces. The next, six scenes were selected to apply three-act structure of scenario and these were analyzed with suggested analysis frame. Analysis frame was made using the three elements-character, event, setting. Each of the element was adapted from scenario elements and they were reorganized for architectural space analysis. As a result of this study, it was found that the characteristics of Genius Loci's spaces are related with three-act structure of scenario. Genius Loci followed the three-act structure of scenario and met its requirements. The study will contribute to the analysis of architectural space to consider the story plot.

This study is assuming that continuous experiences are proportional to viewing satisfaction in a museum. For this reason, this paper researched about the factors of spacial construction which are helping visitors to their satisfaction in a museum. For this purpose, This research studied about Stephen Bitgood’s ‘benefit and cost model’ which suggested that the personal value of continuous experience are related with increasing benefits and reducing costs. however Stephen Bitgood’s studies are limited in terms of ‘benefit’ so, this paper compensated the defects in order to use the ‘benefit and cost model’ for research frame. Suggested research frame was made up of four categories. One is individual factor of benefit, another is relationship factor of benefit, the other is individual factor of cost and the last is relationship factor of cost. Besides, the paper assorted a process of museum trips to research the characteristics of each step. Firstly, in a large percentage of cases, individual factors of benefit were connected with esthetics of the space itself. Secondly, relationship factors of benefit were related with spacial elements that helped to story-making of individuals. Thirdly, individual factors of cost were almost associated with functional aspect such as dimensions or safeties. Fourthly, relationship factors of cost were involved in visitors circulation paths which are inducing malling in museums. 본 연구는 박물관에서의 관람지속이 관람의 만족과 비례한다는 전제 속에서 관람의 지속을 지원하고 유도하는 공간구성요인에 대하여 알아보았다. 이를 위하여 박물관 관람지속의 가치여부는 이익의 증가와 비용의 절감 속에서 나타난다는 스테판 비트굿(Stephen Bitgood)의 이익, 비용 모델을 살펴보았으며, 비용부분에 치우친 문제점을 보완하고 개별적, 관계적 구분을 포함시켜 연구의 방법 틀을 제안하였다. 또한 관람의 시작부터 마침까지를 다섯 단계로 구분하여 각 단계별 특성에 맞는 구성요소를 조사하였다. 연구 결과 관람객이 박물관에서 추구하길 원하는 이익의 개별적 요인들은 대부분 공간 자체의 심미성과 관련되었으며, 관계적 요인들은 주로 관람자 개개인의 이야기 만들기를 통한 자발적 참여를 유도하는데 영향을 주는 공간요인들이었다. 관람을 지속하는데 투자되는 비용과 관련한 개별적 요인들은 주로 단위공간의 크기나 안전성 등 공간의 기능적 측면이었고, 관계적 측면은 타 공간과의 시각연계를 통한 관람자의 지속적인 움직임을 유도하는 요인들이었다. 연구의 결과는 박물관의 복합화 및 엔터테이먼트화 속에서, 타 문화시설과 구별되는 박물관의 본질적 기능인 전시 관람의 재미와 의미를 찾고 확장하는데 기여할 것으로 기대한다.

본 연구는 인공지능 기반의 합성보조지수 모델을 개발하여 경제순환을 예측하는 새로운 방법을 제안한다. 합성보조지수는 다양한 경제지표들을 독립변수로 사용하여 경기선행지수(CLI)와 경기동행지수(CCI)를 예측하고 분석할수 있다. 다중선형회귀모델과 LSTM을 이용하여 모델을 평가하였다. 이 모델은 경기선행지수를 추종하거나 경기동행지수를 추종하는 합성보조지수를 만들 수 있으며, 합성보조지수를 구성하는 독립변수들간의 가중치를 학습시키는 방법으로 딥러닝 모델을 적용할 수 있다. 본 연구의 목적은 인공지능 기반의 합성보조지수 모델을 개발하여 경제순환을 예측하는 것이다. 이를 위해 다음과 같은 방법을 사용하였다. 첫째, 코스피지수, 코스닥 지수, 환율, 국채 10년물 가격, 국채 3년물 가격, 한은기준금리, 구리선물, WTI유 선물, 나스닥종합지수, VIX 지수와 같은 다양한 경제지표들을 독립변수로 사용하여 경기선행지수(CLI)와 경기동행지수(CCI)를 예측하고 분석하였다. 둘째, 다중선형회귀모델과 LSTM을 이용하여 모델을 평가하고 분석하였다. 셋째, 추가로 다양한 딥러닝모형을 연구할 예정이다. 본 연구는 경제순환주기를 예측하여 경영, 경제, 투자 등 전반적인 영역에 도움이 될 뿐만 아니라, 산업계에서도 경기를 예측하고 적절한 대응 전략을 수립하는 데 도움이 될 것으로 기대된다. 또한, 합성보조지수는 경제순환지수의 발표주기가 긴 문제점을 극복하고, 미래의 경기 동향을 신속하고 정확하게 예측할 수 있는 유용한 지표로 사용될 수 있으며, 정책 수립 및 경제에 대한 의사결정을 지원할 수 있다는 잠재력을 가지고 있다. 이 연구는 합성보조지수 모델의 개발과 적용에 관한 기초적인 연구로서, 앞으로 더 다양하고 깊이 있는 연구가 필요하다.

Heterotopia is a representational space of non-mainstream. Therefore, it is not a recognized space, but a space created by the experience of citizens. This study presupposes that Chapel Hill public library has heterotopia characteristics. And the positional meaning was utilized for spatial analysis of heterotopia. First, we looked at the characteristics of Heterotopia of urban cultural space through literature. Second, we searched at the definition of positional meaning. And we looked at the three semantic reactions of the positional meaning. This is a visual relationship, an approach relationship, and a belonging relationship. Third, we investigated the general overview of Chapel Hill Public Library and its program and space composition. Fourth, the positional meaning of Chapel Hill Public Library was analyzed in six scenes. Through this, we looked at the Heterotopia characteristics of Chapel Hill Public Library. As a result, Heterotopia characteristics were found in six scenes of Chapel Hill Public Library. Heterotopia characteristics were oriented toward overcoming homogenization in the mainstream space, Nonhierarchy efforts against hierarchicalization, and the establishment of the totality of fragmented individuals.

The purpose of this study is to suggest the positional meaning of buildings locating in the T-shaped road which is having a distinctive quality. For this study, we researched the reason of generation of the T-shaped road and prepared between the positional meaning to the results of case studies. Firstly, we sought the symmetric forms of buildings which are connected with visual relationship. Secondly, we found out the entrances locating in the middle of the T-shaped road which are connected with accessible relationship.

The purpose is to suggest the spacial type of future elementary classroom based on smart education environments. For this purpose, first, we studied leading researches and case studies about the future classroom and smart education environment. And then we conducted interviews to education expert. Through the studies, we were able to distinguish the differences between physical-environmental and emotional-functional aspects of the future classrooms. The physical-environmental character includes the smart and eco-environments. Emotional-functional character includes the participation, collaboration performance, emotionality, stability and expandability. As a result we proposed the six spacial elements for composing the future classroom. they are co-operational active space, creative-experiential space, emotional-reading space, Exhibition-stage space and ordinary study space. Optimum composition of the 6 elements will be a much better alternative for future classrooms.
