These days, it is getting important to have more chances to visit natural environment for the wellbeing life. The advancement of digital technologies allows us to get useful information regardless of time and location. In this paper, we investigate a way of improving user experience in the natural green environment using the digital technologies. This paper proposes a system called Green-UX-Story which supports users to create and share their story through the online and offline green experience. The system consists of two main systems: the "Story-Field" and the "Story-Tree". The Story-Field consists of a certain number of the Story-Trees allocated to a certain green site. In the Story-Field, users can see the Story-Trees that are owned by other users and share their stories. The Story-Tree contains the user-story in each branch and green information that are captured by the user on the web. The Story-Tree is generated using the L-system algorithm as the user adds stories. The main purpose of the system is to enable users to write their green stories from the both online and offline experiences. This paper describes the system configuration and the user scenario of the Green-UX-story.

A narrative structure is essential for a story generator to create a story plot. In digital storytelling system, a narrative structure can be generally designed as a tree or a graph, and the story generator in the digital storytelling system creates continuous story plots based on the narrative structure. When a narrative structure is designed with a tree or a graph, it is hard for the story generator to create various kinds of story-plots due to the inflexible nature of a tree or graph structure. It may result in degrading the quality of story-plots to provide similar story-plot to various kind of user. In this paper, we proposed an approach to create a story-plot based on association analysis of data mining to overcome the disadvantage. In detail, we defined a narrative structure which consists of narrative patterns, and then implemented a story generator which creates a story-plot using the proposed narrative structure. As a result, we confirmed that implemented story generator was able to create a story-plot according to understanding level of user in case study.

본 연구는 앞서 가족이야기(familyStory)를 중심으로 인터렉티브 스토리텔링을 지원하는 데이터의 서술구조연구를 바탕으로 가족콘텐츠 스토리족보 저작시스템 설계 및 구현에 대한 연구이다. 한 인간이 태어나서 가지게 되는 이름, 생년월일, 가계도와 같이 정체성 있는 1차적 정보와 본인과 가족구성원이 경험하는 업적, 에피소드, 경험 등의 2차적 정보를 '가족콘텐츠'라고 정의한다. 본 저작 시스템에서 제시하는 '스토리가 있는 가계도(족보)'를 한 줄로 정의하면 가계도에 스토리텔링을 적용하여 가족스토리를 만드는 것으로, 현존하는 1세대가 생존기간 동안 한 가족의 광범위한 역사를 이후 세대들에게 남기는 것으로서 매우 가치 있고 중요한 일이다. 가족콘텐츠 스토리족보 저작도구는 1,2세대의 경험적 지식의 이야기를 텍스트, 이미지, 영상 등 디지털 매체를 사용하여 쉽게 저작할 수 있으며, 저작된 다양한 장르의 가족이야기를 가지고 3세대와의 소통을 위한 도구로 활용하거나, 이야기를 재구성하여 창작이야기를 작성하는데 활용 가능하다.

수강생들의 정보와 경험 부족을 극복하기 위해, 의사 결정 트리를 활용한 콘텐츠 기획 트리를 개발하였다. 콘텐츠 기획 트리는 수강생들이 개발할 주제와 스토리를 선택하는 나무 몸통 생성단계, 해당 스토리를 바탕으로 개발 가능한 형태 '범주'를 선택하는 부모 가지 생성단계, 해당 콘텐츠를 효과적으로 제작하는 흥미 '효과'를 선택하는 자식가지 생성단계 그리고 시각화할 멀티미디어 표현 '요소'를 선택하는 잎사귀 생성단계로 구성된다. 교육 모델은 게임기획 디자인과 정보시각화 강의에 적용되었고, 각 강의에서 사용된 범주, 효과 그리고 요소의 예를 사례로 제시한다. 교육 모델은 145개 팀 프로젝트에 사용되었고, 단계별 학습 프로세스로 효율성을 확인하였다.

A Korean endemic and evergreen small tree ' Dendropanax morbifera $L_{EV}$.(Araliaceae)' is a component of evergreen forest and mainly idstributein sourthern region and islands in Korea. A local population of D. morbifera which is located between evergreen and deciduous forest within 50m x 50m quadrate was investigated to ascertain the change of population structure, emergence and growth dynamics of seedlings and saplings, and pattern of spatial distribution by the temproal and spatial expansion of population . The result of analysis of population structure by Importnace Value(IV), evergreen forest showed a high species diversity of evergreen tree species such as Cinnamomum japonicum, Machilus japonica, Neolitsea serica, Daphniphyllum macropodum, Ligustrum japonicum, and etc, in middle and under story than in upper story where Camelia japonica and Quercus acuta were dominant. And in conterminous deciduous fores, the major component of evergreen forest in this region, Camellia japonica, Quercus acuta, evergreen tree of Lauraceae and etc. were abundant in only under story. IV of D. morbifera differed from among three story. In comparative analysis of emergence and growth dynamics of D. morbifera seedlings and saplings between evergreen and deciduous forest, emergece and density of seedlings were significantly greater in evergreen than in deciduous forest, and growth of height and basal diameter of seedlings and saplings were slightly larger in evergreen than in deciduous forest. The spatial distribution patterns by Moristia's index mapping of indivuduals using a lattice method of XY axis within this population showed that seedlings(age up to 2 years) and saplings (age>2 years and height<1m) both evergreen and deciduous forest were more or less aggregated apart from mature trees, and thougth intermediate trees(height>1m and dbh<10cm) had a aggregated distribution pattern, mature trees(dbh>10cm were uniform. In conclusion , the expansion of D. morbfera population from evergreen to deciduous forest accompanied with a mumber of evergreen woody species, and also, emergence and recruitment, and growth of seedlings were greatly influenced moisture and canopy by around community structure.

The purpose of this study was to evaluate the seismic performance of weak-axis column-tree type connections used in steel moment frames. These connections are composed of a shop-welded and fieldbolted steel structure and can improve welding quality. On this basis, column-tree type connections are widely used in steel moment resisting frames in Korea and Japan. In this study, splices designed with a semirigid concept regarding the seismic performance of column-tree connections were experimentally evaluated. The structures can absorb energy in an inelastic state rather than the elastic state of the structures by the capacity design method. For this reason, the plastic hinge might be located at the splice connection at the weak-axis column-tree connection by reducing the splice plate thickness. The main variable was the distance from the edge of the column flange to the beam splice. CTY series specimens having column-tree connections with splice length of 600 mm and 900 mm were designed, respectively. For comparison with two specimens with the main variable, a base specimen with a weak-axis column-tree connection was fabricated and tested. The test results of three full-scale test specimens showed that the CTY series specimens successfully developed ductile behavior without brittle fracture until 5% story drift ratio. Although the base specimen reached a 5% story drift ratio, brittle fracture was detected at the backing bar near the beam-to-column connection. Comparing the energy dissipation capacity for each specimen, the CTY series specimens dissipated more energy than the base specimen.
