In this paper, we analyzed audience satisfaction procedures in performing art, specifically in musical, in terms of Expectation Disconfirmation Theory. We analyzed one's expectations and outcomes over time; we first classified audience expectations and outcomes about environmental elements as 'the first expectation'/'the first outcome' and about watching situation & content itself as 'the second expectation'/'the second outcome', then analyzed by comparing those two. Through surveying and analyzing the result, this paper serves that the ultimate fact which affects on the final audience satisfaction is 'the second outcome', which is the outcome about watching situation & content itself. This paper also shows that audience expectation toward physical quality of environment affects to 'the second expectation', then 'the second expectation' affects to 'the second outcome', so then affects to the final satisfaction. However, 'the first outcome' doesn't affect to 'the second expectation'; in other words, the physical environment does not affect much to the audience final satisfaction. We expect that our study provides clues for venue management in performing arts.

The purpose of this study is to investigate the various perspectives that children can provide by utilizing specific physical spaces for play, and to study how to effectively apply them to surrounding spaces and environments. AHP was used to analyze the preferred elements for effectively designing a play area. The main keywords were derived through case studies of various domestic and foreign play space designs, and each keyword was grouped and a keyword of a higher concept was derived. The results of the comparison of 14 keywords that were finally drawn using AHP for each element were used to derive the priority for the preferred elements. As a result, preference was derived in the order of "Openness", "Safety", and "Diversity" in the morphological properties of the play space, and "Adventure", "Five senses elements", "Visual elements" and "Interactivity" in the content properties of the play space.

This study aimed to find out the formation of ecologically educational place identity of nature trails in national parks, which elementary school students to adults can understand, by analyzing the connectivity between characteristics (signs) of nature trails and elementary science environment-related key concepts and the domain of ecological education in the course of environment and by developing a semiotic interpretation model of place identity based on Barthes's semiotic theory. When analyzing correlations between the interpretation board-focused surrounding environment of nature trails and the content system of ecological education, this study found out that it showed the highest connectivity with the domain of 'System of Ecological Environment'. When analyzing the formation of place identity of nature trails in terms of semiotics, this study discovered that geographical locations or landscapes, artificial environments and physical elements as characteristics of surrounding environments mostly acted on the formation of placeness. Besides, it was found that both knowledge and attachment elements equally could act on the formation of a sense of place. Being likely to develop through interaction between placeness and a sense of place, place identity was mostly composed of behavioral internal stages and sympathetic internal stages. To diversify the formation of place identity, however, this study found it necessary to develop environment education projects and create surrounding environments and interpretation boards with the environmental uniqueness of nature trails reflected much more.

무선 센서 네트워크의 센서 노드들은 한번 배치되면 다시 회수되지 않으며, 외부 전원의 공급 없이 배터리만을 사용하여 작동하게 된다. 따라서 각 센서 노드는 매우 제한된 자원을 사용하여 환경을 감지하거나 주변 노드들과 통신을 해야 한다. 결국 무선 센서 네트워크에서 가장 중요한 요소는 센서 노드가 소모하는 에너지를 최대한 절약하여 네트워크의 수명을 늘리는 것이라고 할 수 있다. 본 논문에서는 에너지 효율적인 그라디언트 기반의 라우팅 기법을 제안한다. 이 기법은 패킷 발생 및 전달 횟수를 새로운 메트릭으로 사용하여 주변 노드의 에너지 사용량을 추정한다. 이를 통하여 에너지 소모가 특정 노드에게 집중되지 않도록 기존의 그라디언트 라우팅을 개선하였으며, 패킷 듣기(Packet Overhearing) 방식을 통하여 별도로 메시지를 주고받는 일 없이 메트릭을 측정할 수 있도록 하였다.

본 연구에서는 침출수를 비롯한 매립지의 각종 오염물질 배출로 수자원이 오염되어 피폭체의 피해가 빈발하는 문제를 해결하기 위해서, 매립지의 상대적 유해성을 평가하여 한정된 환경관리 예산의 합리적 배분을 위한 우선순위를 결정할 수 있는 의사결정 지원도구로서 LHR(Landfill Site Hazard Ranking)모형을 개발했다. LHR모형은 다요소의사결정(多要素意思決) 기법에 정성적 위해성(危害性) 평가기법을 접맥시켜 주관적 가중치를 모형에 반영한 가치내재화(價値內在化) 모형이다. LHR모형은 피폭체의 주요 피폭경로를 지하수 이동경로와 지표수 이동경로로 보았으며, 각 이동경로별로 누출 가능성, 폐기물 특성 및 피폭체 특성으로 요소범주를 3종류로 구분하여 폐기물의 독성이나 매립량같은 특성이 매립지의 수리지질학적 요소 및 자연지리적 요소에 의해 결정되는 오염물질의 누출 가능성을 통해 매립지 주변의 지역주민과 취약한 수생태계 같은 피폭체에 끼치는 매립지의 유해성을 상대적으로 평가했다. 그리고 LHR모형에서는 매립지 유해성을 공기 이동경로 및 사회경제적 측면에서도 평가하기 위해 매립지 이격거리별 토지이용 형태의 유해성을 평가했다. 그리고 각 평가요소별 가중치는 위계분석과정(位階分析過程)의 쌍대비교법(雙對比較法)에 의하여 할당했으며, 민감도 분석으로 LHR모형을 검증했다.

연안지역은 강우, 조위, 월파 등 다양한 재해 요소에 의해 침수될 수 있다. 또한, 이러한 재해 요소는 동시에 발생하여 큰 침수 피해를 유발하기도 한다. 하지만 각각의 재해 요소를 대상으로 하는 기술 분야가 상이하기 때문에 물리 모형 기반의 과학적 방법으로 복합적인 재해 요소를 고려한 침수 분석에 관한 연구는 제약되었다. 이 연구는 강우-유출 및 2차원 지표면 흐름 해석의 수공학적 분석 기술과 조석, 파랑, 월파 등의 해양공학적 기술을 연계하여 연안지역에 대한 복합 외력을 고려한 침수 분석 기술을 제시하는데 목적이 있다. 우선, 먼 바다로부터 예상되는 파랑, 조위 분석에는 ADCIRC와 UnSWAN 모형을 연계한 ADCSWAN이 사용되었다. 연안 주변의 복잡한 흐름 해석과 해안 구조물을 범람하여 발생하는 월파량 산정에는 FLOW-3D 모형을 이용하였다. 그리고 강우-유출 분석과 바다의 조위 및 월파량을 고려할 수 있을 뿐만 아니라 2차원 지표면 침수 해석이 가능한 XP-SWMM을 이용하여 연안지역의 침수 모의를 수행하였다. 모형 간 연계에 의한침수 해석의 적절성을 검토하기 위해 2016년 10월의 태풍 차바 시 대대적인 침수가 발생한 부산 마린시티 지역에 대하여 적용하였다. 침수 모의 결과는 당시의 현장 사진, 침수흔적도와 비교하여 검토되었고, 실제 침수 현상과 유사한 결과가 도출되었다. 이 연구는 연안지역의 복합적인 재해요인에 대한 침수 해석에 수문 분야와 해양공학 분야의 기술 연계를 통해 실제 현상의 재현성을 높인 것에 의의가 있다. 또한, 이 연구에서 제시한 해석 방법은 다양한 연안지역의 침수 원인 분석과 적절한 재해 방지 대책 수립에 활용될 수 있을 것으로 판단된다.

Highway design speed is a very important design element which determines highway design level. When determining highway design speed, one would estimate it utilizing the most likelihood of design speed and vehicle operating speed relationship. Existing operating speed prediction models only include highway geometric characteristics and their impacts on speed, which usually can not consider the impact of highway design speed on surrounding roadway environment and land use pattern. If this happens, excessive highway construction cost and huge environmental impact can occur. In this research project, a new vehicle operating speed prediction model was developed which can reflect the effect of surrounding roadway environment into vehicle speed prediction. The followings are the research findings : Firstly, highway terrain types and land use pattern on national roads were classified and integrated into drivers' visual recognition pattern. This was performed using a data management software. Secondly, the developed highway terrain types and land use pattern were related to vehicle speeds and it was found that there were significant statistical differences among vehicle speed for each different terrain and land use pattern. Thirdly. the General Linear Model analysis was employed to analyze the effects of highway geometric features, terrain types, and land use patterns. For two-lane highway and four-lane highway tested in this research project, it was found that R squares were 0.67 and 0.85, respectively. Additionally an optimal highway design speed range table, based on this research project. was proposed for practical use. This table can be reliably used on South Korean national road design, but discretion is required for applying this table to other types of highways including provincial roads and municipal roads.

This paper is concerned with developing infinite elements which are applicable to wave diffraction and radiation problems in the vertical plane. The near need region surrounding the solid body is modeled using conventional finite elements. but the far fold region is represented using the infinite elements developed in this study. The shape functions for the infinite elements are derived from the analytical eigenseries solution of the scattered waves in the far field region. The system matrices of the elements are constructed by performing the integration in the infinite direction analytically to achieve computational efficiency. Numerical analysis is carried out for two floating bodies with different cross-sectional shapes to prove the efficiency and validity of the elements. Numerical experiments are also performed to determine the suitable location of the infinite elements which directly affect accuracy and efficiency of the solution.
