The existential space concept which introduced the sense of place that began emerging recently together with the change of space concept results from people's fundamental existential humane aspect as the subject of perceptive experience. The tendencies of enlargement layering and diversification which we can see in contemporary architecture imply the possibility that elements of urban image can be incorporated into interior design. This study utilizes Kevin Lynch's theory which tries to relate environment to existential space. In this study we re-analyze and apply Lynch's $\ulcorner$the Theory of Urban Image$\lrcorner$to interior space and using the conclusion from a case study examine the applicability of the theory about visual perception to interior design. This study considers a new method of analysis to perceive and grasp interior space through the understanding of the cognitive map and image concept.

Structural control technologies have attracted great interest from the earthquake engineering community over the last few decades as an effective method of reducing undesired structural responses. Traditional structural control systems employ large quantities of cables to connect structural sensors, actuators, and controllers into one integrated system. To reduce the high-costs associated with labor-intensive installations, wireless communication can serve as an alternative real-time communication link between the nodes of a control system. A prototype wireless structural sensing and control system has been physically implemented and its performance verified in large-scale shake table tests. This paper introduces the design of this prototype system and investigates the feasibility of employing decentralized and partially decentralized control strategies to mitigate the challenge of communication latencies associated with wireless sensor networks. Closed-loop feedback control algorithms are embedded within the wireless sensor prototypes allowing them to serve as controllers in the control system. To validate the embedment of control algorithms, a 3-story half-scale steel structure is employed with magnetorheological (MR) dampers installed on each floor. Both numerical simulation and experimental results show that decentralized control solutions can be very effective in attaining the optimal performance of the wireless control system.

The usage of this paper is to analyze the characteristics of architectural publicity expressed in the spaces of mixed-use facilities in Japan. The research method was as follows: 1) preparatory study and literature research review to extract the elements of architectural publicity 2) A survey, to check architectural publicity elements 3) Based on the elements of architectural publicity, each mixed-use facility was evaluated; 4) Spaces of the facilities were classified based on Kevin Lynch's. The Image of the City element. The results show that the mixed-use facilities Include aspects of "space use aspect" and "space structural aspect". Second, the entrance areas of the facilities were characterized by strengthened spatial legibility and sense of area. Third, the paths were characterized by visual openness, accessibility, inter-relatedness, and space amenity, Fourth, the spaces that perform certain functions within the facilities were characterized by improved space amenity, convenience, and social interchange. Fifth, the nodes were characterized by increased social interchange and spatial transferability. Sixth, the landmark spaces were characterized by improved spatial legibility.

This study evaluated the Hook-up installation of an offshore site construction process, which is the final step in an offshore site installation process. During Hook-up installation, the offshore structure can have a detrimental effect on the work stability due to low-frequency motion. Moreover, economic costs can be incurred by the increase in available days of a tugboat. Therefore, this study developed a numerical analysis program to assess the dynamic behavior of mooring systems during hook-up installation to analyze the generally performed installation process and determine when the tugboat should be released. In this program, the behavior of an offshore structure was calculated using Cummin's time-domain motion equation, and the mooring system was calculated by Lumped mass method (LMM). In addition, a tugboat algorithm for hook-up installation was developed to apply the Hook-up procedure. The model used in the calculations was the barge type assuming FPSO (Floating production storage and off-loading) and has a taut mooring system connected to 16 mooring lines. The results of the simulation were verified by comparing with both MOSES, which is a commercial program, and a calculation method for restoring coefficient matrix, which was introduced by Patel and Lynch (1982). Finally, the offset of the structure according to the number of tugboats was calculated using the hook-up simulation, and the significant value was used to represent the calculation result.

유용성 평가는 컴퓨터를 사용함에 있어 사용자 인터페이스를 설계하는데 가장 고려되어져야 할 중요한 측면이다. 유용성 평가 방법은 Human Computer Interaction(HCI) 전문가들이 주로 사용하는데, 가장 보편적으로 많이 사용되는 Nielsen이 제시한 평가 기준은 한국 실정에서 실제로 검증된 바가 없다. 지난 연구에서 Nielsen의 heuristics은 일반적인 부분들이 많아 적용하기가 너무 보편적일 수 있고, 또 평가 기준이 영어로 되어 있어 문화적 차이 등의 이유로 몇 가지 기준들이 이해하고 적용되기 어려웠다는 것을 발견하였다. 이에 본 연구에서는 유용성 평가에서 대표적으로 사용되는 Jakob Nielsen의 10가지 usability heuristics를 컴퓨터 전문가 집단을 대상으로 설문조사하여 유용성 정도와 삭제 및 추가 평가 기준의 논리적 근거를 마련하였다. 본 연구에서 분석된 결과물은 추후 새로운 평가 기준안을 도출하는데 많은 도움이 될 것이다.

본 연구는 전 세계의 관심을 받는 한반도의 판문점과 주변 DMZ의 가치를 제대로 보여줄 원천 스토리 발굴과 콘텐츠 개발 및 활용방안에 관한 연구이다. 판문점과 주변 DMZ의 고품격 브랜드화를 위한 연구로 세 가지 방법을 사용하였다. 첫 번째는 조셉 캠벨의 '영웅의 여행'이론을 이용, 여행 사이클을 통한 예비 방문객의 흥미 유발 부분이다. 두 번째는 현대 여행의 트렌드인 주관적 여행과 감성 자극 부분에 롤랑 바르트의 '제3의 의미'를 접목해보았다. 세 번째는 케빈 린치의 이론을 도입해 핵심장소인 판문점이라는 공간에 경로, 경계, 구역, 교차점, 랜드마크의 다섯 가지 요소를 배치해 보았다. 연구를 통해 판문점과 주변 DMZ의 콘텐츠 발굴은 역사적 사건의 정리와 더불어 관련 인물들의 이야기를 듣는 직접인터뷰 방식을 이용해 제3의 의미까지 수집할 필요가 있다. 80세 이상의 대상자를 우선순위로 진행하며 적어도 3번 이상 그리고 3대에 걸쳐 인터뷰가 이루어져야 한다. 이를 아카이브로 구축하고 스토리를 선별한 후 문화 콜라주 작업을 거치며 네트워크화와 브랜드화로 이어지는 과정은 5단계에 걸쳐 이루어진다. 이를 통해 원천 스토리 발굴-스토리텔링을 통한 콘텐츠 가공-콘텐츠 활용-지역 일자리 창출-지역경제 활성화라는 선순환의 구조를 만들어 낼 수 있다. 콘텐츠 개발은 시간성, 역사성, 장소성, 고유성, 진정성을 살리면서도 감성을 건드릴 수 있어야 한다. 관광과 여행, 개발과 훼손의 우려 사이에서 중심을 잡으며 신중하면서도 장기적인 계획과 다량의 원천 스토리 발굴이 이루어져야 하고, 적절한 스토리텔링이 필요함에 대한 공감대 형성이 요구된다.
