In case of stone pagoda structures, the various construction types appear, and various damages occur due to exposure to the outdoors for a long time. Such damages can be classified into non-structural damages and structural damages. However, studies for the effects of structural damages on stone pagoda structures are insufficient. Accordingly, this study intends to perform structural modeling and structural analysis according to structural damages of stone pagoda structure, and to perform risk analysis through the fragility curve. So, we expects that this study gives a great contribution to the preservation and maintenance of stone pagoda structures under the various structural damages.

In the study, a shape finding procedure for the tensegrity system model inspired by the movement pattern of animal backbone was presented. The proposed system is allowing a dynamic movement by introducing the concept of “saddle” for the variable tensegrity structure. Mathematical process and an algorithm for movable tensegrity to specified points were established. Several examples have applied with in established shape finding analysis procedure. The final tensegrity structures were determined well to a object shape.

The purpose of this study is to explore the value structure of sharing economy for consumers, and to construct a model of consumers' continuoususe intentionin the sharing economy. Firstly, based on the characteristics of sharing economy platform technology, this paper explores the composition of platform value (time adaptability, location adaptability, content accessibility) through qualitative analysis. Then through quantitative analysis, this paper explores the influence of platform value on consumers' perception of emotional value and economic value. Finally, on this basis, this paper studies the impact of consumer value of sharing economy on consumer behavior, and compares and analyzes the impact of consumer value of sharing economy on consumers under different product types. In short, this paper aims to study the value creation of sharing economy from the perspective of consumption value, and shape its future development direction.

This study considers the process of regional Re-Birth against the depopulation of Teshima, located in the Seto Inland Sea (Tonosho-town, Shodo-district, Kagawa Prefecture). The island was the subject of a scandal with largest illegal industrial waste since the 1970s. Now, the industrial waste issue on the island is mainly removed the ART SETOUCHI, art festival, attracted 150,000 visitors in 2016, and is held once every three years. The study focuses on the effects of ART SETOUCHI (Contemporary art festival) and the regional characteristics (especially focusing on local foods). Based on these two key characteristics, the structure model of Re-Birth aimed CSV, that is, balancing economic value and social value by Value Co-Creation among various actors centered on Local residents and New residents. In this study, Value Co-Creation defines value recognition by Local residents and New residents, based on the concept of value co-creation (4C's approach) by Muramatsu (2015) , S-D-Logic by Vargo and Lush (2004) and S-Logic by Grönroos (2006). This study explores not only the structure model of Re-Birth, but also how to adapt the model even in such harsh environmental areas, like Fukushima, suffering with depopulation, aging, and reputational damage. We see that, Regional Re-Birth means, the story that Local residents and New residents aim to establish the self-government system to have initiatives against the negative state refined as polluted land. At such time, independent, self-reliance, and self-consideration are important factors as condition of Value Co-Creation.

In previous studies, the pressure distribution on optical mirror surface was measured by CFD analysis assuming various external air conditions on optical structures designed using knowledge-based design techniques. In this study, the KBD model was verified by comparing the pressure data from the mirror surface obtained through CFD analysis with the pressure values from the wind tunnel test of the actual model.

본 연구에서는 인공신경망을 이용해 건물 구조물의 가속도계 설치 위치 및 개수를 선정하는 방법을 제안한다. 인공신경망의 입력 층에는 층에 설치되는 가속도계로부터 얻는 가속도이력데이터가 입력되며, 출력층에는 구조물을 정의하는 각 층의 질량과 강성 값을 출력하도록 신경망을 구성한다. 가속도계의 설치 위치 및 개수를 선정하기 위해 여러 설치 시나리오를 가정하고 훈련을 통해 인공신경망을 구한다. 훈련에 사용되지 않은 예제를 이용해 예측 성능을 비교하였다. 센서 개수 및 위치에 따른 예측 성능을 비교하여 설치위치 및 개수를 선정한다. 6층과 10층 예제 적용을 통해 제안하는 방법을 검증하였다.

제주도 곶자왈 시험림을 대상으로 산림유형을 분류하고 식생구조 특성을 평가하였다. 현지조사를 통해 수집된 수종별 흉고단면적을 이용한 계층적 군집분석을 실시하여 5가지 산림유형으로 분류하였다. 제주도 곶자왈 시험림의 산림유형은 중요치를 고려하여 종가시나무 순림, 종가시나무 우점림, 편백 우점림, 활엽수혼효림, 침활혼효림으로 각각 명명하였다. 종가시나무 우점림과 편백 우점림은 숲 틈의 인위적 조성이 필요할 것으로 보이며, 종가시나무 순림, 활엽수혼효림은 지속적인 모니터링을 통해 교란 위협으로부터 보호가 우선되어야 할 것으로 판단된다. 침활혼효림은 소나무 재선충병 피해지이므로, 고사목 발생으로 인한 식생 교란에 대비해야 할 것으로 보인다. 본 연구는 곶자왈 지역의 산림자원 보전전략 수립에 기여할 것으로 기대된다.
