The robot for narrow space is used in searching, investigating or cleaning. Up to now variety of researches on in-pipe robots have been introduced. However it is still hard to overcome vertical or curved passage. In most cases of narrow space robots are able to travel just aimed diameter which was selected when those are developed. Also, a large percentage of robots are not able to detect the configuration of pipe or circumstance. In this paper we present a robot called PAROYSⅡ for narrow space with vertical and curved passage. This proposed robot is not affected at all to variance of pipes, vertical or horizontal passages, curved pipes, projecting parts and parallel planes. In addition to that, it will perceive the internal configuration of pipe and terrain, which will be not only available to control navigating scheme by itself, but also mappable about the passage which the robot traveled. Core points in the design and structure are introduced and preliminary verification is given.

In this paper, we report a small-scale emerging island and double arc loops, which are associated with a M6.5 flare, in Active Region 12371. We investigate the spatial and temporal changes of both photospheric magnetic fields using SDO/HMI data and coronal magnetic structures obtained from nonliner force-free field (NLFFF) extrapolation. From the vector magnetograms, we find a small-scale emerging island near the main polarityy inversion line about three hours before the flare. The island has a strong shear angle, which is determined by difference between transverse component of observed field and potential field, of around 90 degrees. Furthermore, the NLFFF well reproduces a sigmoidal structure seen in SDO/AIA 94, which is consistent with the double arc loops configuration suggested by Ishiguro and Kusano (2017) who introduced a magnetic configuration showing the double arc instability. The observed emerging island is located among the double arc loops, which is also supproted by their model. Finally, there was an eruption (M6.5 flare) associated with the loops. We discuss a possible role of the double arc instability for the eruption.

Korea Protestant slower growth and social church's changes in the environment of the traditional worship center for the sermon to a variety of changes was required, because of this period reflects the availability of a new type of worship was to appear. These changes in the type of worship in the form of the worship space, and space configuration is affecting many more. This study was the type of church korea today, the type is classified as a traditional worship and contemporary worship, and to characterize the category by a change in the type of church worship space in the configuration that affects cases throughout the analysis was to investigate, study follows. Traditional worship the center of the altar, the altar placed platform form, a vertical elevation of the platform sheet form, the installation of the cross, place the side of the choir seats, church chair type attribute appears tradition and in part compressed pulpit appears symbolism. Contemporary worship to the exclusion of the symbolic elements of the platform open, flat sheet form and the platform was the preferred form of minor elevations of the flat, multi-purpose space used for worship to sermon platform placed around the altar of the adjustable type, the choir seats placed in scheelite, preferred form of scheelite was an individual chair. However, the characteristics of traditional and contemporary worship space features a mix of worship space, quite a lot of cases that have been found. Integrated and consistent element of the worship space, the worship of the discrepancy in the form of systematic theological depth analysis did not come true without lust about contemporary culture is changing rapidly to accommodate sprawl is judged. Therefore, the characteristics of the type of worship and prayer to understand the changes in the church building is a prerequisite to be a very important aspect.

여가공간에서의 경험은 이용객들이 움직이는 동안 직접적이고 연속적인 시각적 접촉을 통해 형성된다. 이용객의 움직임은 획득하는 지식과 정보의 양을 결정하는 중요한 인자이다. 따라서 이용객의 움직임을 고려한 보행동선은 시설이용을 용이하게 하여 쾌적하고 활력적인 공간을 조성하는 필수적인 요소이다. 합리적인 동선계획은 공간의 이용 및 활성화, 만족도에 영향을 주고, 궁극적으로 공간의 이용가치를 증대시키는 수단이고, 무질서한 동선체계는 길찾기(wayfinding)의 어려움으로 인해 부정적 경험을 유발한다. 본 연구는 공간구문론(Space Syntax)을 활용하여 여가공간의 공간구조 지표와 보행량의 상관관계, 방문객의 움직임 등 보행동선 체계를 분석하였다. 연구대상지인 외암마을은 민속마을로 지정되어 많은 관람객이 방문하는 전통마을로 정주공간이 여가공간으로 이용되고 있는 대표적 사례이다. 연구 결과, 외암마을의 보행동선 구조는 전형적인 트리(tree)구조를 지니고 있어 자연스러운 동선을 형성하고 있지만, 여가공간의 측면에서는 공간의 인지도가 낮아 방문객들이 공간체험 시 길을 잃을 위험이 많고, 경제적인 관람을 유도하기가 어려운 구조를 가진 것으로 분석되었다. 따라서 정주공간인 전통마을이 여가공간으로 이용되는 과정에서는 추가적으로 보행체계의 조정과 보충이 필요하다. 또한, 공간구문론은 다른 유형의 여가공간에서 공간구조 및 보행체계 분석에 적용할 필요가 있다.

Public libraries in Korea have undergone changes from libraries for just reading or keeping books to libraries with cultural facilities that provide information through various media. It was because of the "plan for building the information-oriented library" in 2000 that made the complexation of public library in progress. The alterations of the system have changed the structure as well as the grade ranks but haven't been considered enough for administrators or visitors. Hereupon, we are to study of the features by analyzing how the application of the system changed the structure of library. There are four stages in research methods. First, concept of public library and functional elements requested in the process of complexation were studied from literature. Second, vertical, horizontal and circulate changes were studied by applying subject libraries into prior research stereotyping the libraries. Third, mutual relations between each place were studied through J-Graph by elements. Lastly, rank changes according to centrality of space and users were quantitatively studied with space syntax. 4 notable changes were found in these analyses. (1)Vertical, horizontal and circulate structure of public libraries were homogenized. Since 2001, however, they have become diversified as all-in-one or detachable. (2)The space structure of library before 2001 was shallow tree shape while in 2001, period of transition, was the tree shape mixed with ring shape. As time goes on, it has become shallow tree shape again but connected by ring shape in part of reading and common space and in digital reference room. (3)Digital reference room was center of the space around 2001 and it ranked top for integration. After 2007, however, it has become setting off-center. (4)About the purpose of using public libraries, using it as space for administrators ranked top followed by space for visitors and common space before. For now, common space ranks top and space for visitors and administrators. 5 subject public libraries were selected respectively before and after 2001.

This study was designed to derive the characteristics of shared space composition of shared housing for one-person household through an examination on domestic and overseas cases. To examine the systematic approach to the planning of shared space, the concept and current status of shared housing were analyzed; and, the concept of shared space was derived based on the concept of Altman and, through the analysis on cases of shared housing, the shared space was classified into shared spaces for living support, passage, and community. And then, based on the standard of classification of shared space, the configuration of shared space in shared housing was examined through the analysis on domestic and oversea cases. Thereby, the arrangement and function of each type of compartment in shared space were examined and the configuration of the shared space prepared for an entrance of residents was analyzed and classified into 6 types. Each type revealed a relationship between privacy, living, passage and internal community which were all provided with respective configurative characteristics of each space. Result obtained from this study is estimated that they could be used as a basic data for the design or planning of shared spaces in shared and further, they could also be employed for the design or development of shared spaces of such houses taken the type and characteristics of residents into account.

The premise of this study is that an ultimate objective in planning an exhibition space is visitors' experiences created by a result of their first-hand experiences and responses within an exhibition space, and this result can be recognized in the visitors' movement. Thus, the exhibition layout that can directly affects viewers' main line of flow and movement patterns was examined vis--vis a mutually complementary relation in a triangular composition with the structure of exhibition space and the exhibition contents. This study, with the subjects of standing exhibit halls of Gwacheon National Science Museum, Daejeon National Science Museum, and Tokyo National Museum of Emerging Science and Innovation, analyzed 'the correlation between the configuration of the exhibition area and the visitors' movement. The targeted subjects were analyzed from the perspectives of type of architectural space and organization of the exhibition method, and the purpose of this study was to find a spatial evidence to predict the spectator movement formed within the exhibition halls of science museums. The main indicators used are: Based on the investigation/analysis as described above, the following conclusion could be drawn. Diversity of exhibition environment and spectator movement: besides the two big categories of the types of architectural space and types of exhibition method, the construction of vertical circulation and size and shape of the exhibition space, distribution characteristics of exhibition medium, organization of symbolic space and such other diverse organizations and combinations of exhibition environment are implied to have the capability to alter the scope and degree of predicting spectator movement. As an example, the types of architectural space comprising the wide-area viewing circulation was found to be able to change the system of planar circulation according to the composition of vertical circulation. Along with this, it was implied that the format of architectural space influences the form of the exhibition space, and may also act as a factor directly influencing the diversity and arrangement of the exhibition methods. That is, the spatial elements comprising the exhibition environment acts inter-complexly, and exhibits characteristics of limiting or controlling spectator movement.
