Chang Hyon-Gwang(1554-1637) compared the relationship between Ipam and the 28 places with that of the Polestar and 28 constellations. And he considered the ipam to be the core of the universe. This paper aims to identify the meaning of christening to the places for him. I analyzed contents of Chang's , and which preserved the traditional view of the site and writings. As a result, christening to the natural places mean that promote the environment for housing. It is a architecture by itself.

The Periplus of the Erythraean Sea is a Roman period guide to trade and navigation in the Indian Ocean. Justly famous for offering a contemporary and descriptive account of early Indian Ocean trade, the work has been subject to and a point of departure for numerous studies. Its extensive influence on scholarship is, however, also problematic, as it reflects the limited information and cultural and personal bias of its unknown author. Arguably this might have led scholars to overemphasise so-called western or Roman participation in early Indian Ocean trade. Network analysis allows us to map, visualize and measure interconnectedness in the Periplus Maris Erythraei. Many of these connections are not explicitly mentioned in the text, but by connecting not only places with places, but also products with places that export and import them, we get a partly different impression of Indian Ocean trade from that conventionally gathered from the Periplus. It allows us to ask questions about the relationship between coastal cabotage and transoceanic shipping, to identify regional trading circuits, and unexpected centres of long-distance exchange.

In this paper, we present a practical place and object recognition method for guiding visitors in building environments. Recognizing places or objects in real world can be a difficult problem due to motion blur and camera noise. In this work, we present a modeling method based on the bidirectional interaction between places and objects for simultaneous reinforcement for the robust recognition. The unification of visual context including scene context, object context, and temporal context is also. The proposed system has been tested to guide visitors in a large scale building environment (10 topological places, 80 3D objects).

The purpose of this study was to identify the relationship between family-friendly policies in working places and the childbearing intentions of married-employed women. The analysis included 415 married working women from the 2012 wave of the Korean Longitudinal Survey of Women and Family. The factors influencing the childbearing intentions of the women were age, education, number of children under age 18, childbirth leave, childcare facilities, and flextime. The women whose work-places provided childbirth leave had stronger childbearing intentions. The women under age 35 had stronger childbearing intentions when their work-places had flextime policies. In conclusion, my recommendation is that the government should pay more attention to the micro-personal factors, such as the Family-friendly Workplace Practices proposed in this study, when executing policies to reverse the current trend of low fertility.

The standard of living has been getting higher by reason of industrialization and economic growth. It makes people have more cultural desire(wants). Because of reasons mentioned above, a number of entertainment place and performance with high-tech is increased. This has been brought also increasing a number of electrical accident such as electrical shock, electrical fires and accidents of electrical facilities. This paper suggests technical, operational and special precautions of actual electric main line systems in entertainment places and is also written on the purpose of being applied with related provisions to designing electrical facilities, construction, check-up and inspection and maintenance for preventing further electrical disasters in entertainment places.

This paper proposes a way to measure the displacement of a multi-point by using a pattern recognition from video signal. Generally in measuring displacement, gab sensor, which is a displacement sensor, is used. However, it is difficult to measure displacement by using a common sensor in places where it is unsuitable to attach a sensor, such as high-temperature areas or radioactive places. In this kind of places, non-contact methods should be used to measure displacement and in this study, images of CCD camera were used. When multi-point is measure by using a pattern recognition, it is possible to measure displacement with a non-contact method. It is simple to install and multi-point displacement measuring device so that it is advantageous to solve problems of spatial constraints.

This paper investigated the human distribution in subway station areas in Seoul, using geotweets and subway ridership data. Eight stations were selected from the districts of Gangnam and Gangbuk. Geotweets located within a 600-meter radius of the central coordinates of each station were extracted, and distances between the center of station and each tweet location were calculated. Donut-shaped dimension and pie-shaped dimension were generated, using the Haversine distance formula and the Azimuth angle formula respectively. By combining the two dimensions, Dartboard-shaped space division is created. Popular places within the subway station areas identified from this research are almost the same as the current well-known popular places, and this is an important case showing that people send tweets from various places where they engage in daily activities. We expect this study can be a methodological guideline for social scientists who use spatio-temporal or GPS data for their research.

해상에서 발생하는 대형 해양사고는 재산상의 손실뿐만 아니라 심각한 해양환경 오염피해를 유발하고 있다. 국제해사기구(IMO)에서는 해양사고 발생으로 인한 2차적인 해양환경오염 피해를 최소화하기 위하여 "원조를 필요로 하는 선박"에 선박 피난처를 제공하도록 결의서 Res. A.949(23)로 채택하였다. 해상교통 환경 요소 등에 의한 데이터를 바탕으로 종합적인 측면에서 잠재적 위험평가를 실시하여 위험도의 레벨이 일정한 크기를 초과하게 되면 피난처로 지정될 필요가 있고, 선박의 통항안전성, 혼잡도 및 위험도의 정량화/표준화된 기술을 기반으로 선박 피난처 지정 시스템 기술개발이 시급하다. 또한, 선박 피난처를 지정하는 문제는 연안국의 자연환경을 보호하기 위한 국가 정책과 밀접한 관련이 있기 때문에 관련 법안을 마련하는 것이 최우선이다. 본 연구에서는 선박 피난처를 지정 운영하고 있는 외국 사례 분석을 통해 효율적인 국내 선박 피난처 도입방안을 마련하고자 하였다.

Movable scaffolding has been used to work in high places. The scaffolding is economical and convenient to move to other places, but it has the risk of falling down. This paper proposes a fixed bracing system to prevent the falling down of a movable scaffolding, and evaluates its usability by making a small-sized model. Further studies of structural stability, safety, and economical efficiency is necessary to use the system practically.
