In the present paper, we are to find the conditions that a cubic Finsler space is a Berwald space and a two-dimensional cubic Finsler space is a Landsberg space. It is shown that if a two-dimensional cubic Finsler space is a Landsberg space, then it is a Berwald space.

This study aims to identify the Spatial Changes and the main agent of space creation in Samrye Area during the Japanese Occupation Period. As for the urban space in the Samrye area, the urban space was expanded to the Hujeong-ri area from the construction of the Jeonbuk light railway. Before 1914, the urban space of Samrye was formed around Samrye Station in Samrye-ri, which oversees Samrye-do from the Goryeo Dynasty to the Joseon Dynasty, but when Samrye Station of Jeonbuk light railway was established in Hujeong-ri in 1914, the foundation of a ladder-type street network visible from the central space of the current Samrye area was formed until the 1930s. And it was the Japanese and Korean landowners who took the lead in the construction of the Jeonbuk light railway, not the government, who expanded the urban space of Samnye from Samrye-ri to Hujeong-ri. The background of the establishment of Jeonbuk light railway is the reason why Dongsan Farm has difficulty in transporting rice to the Honam Line during the rice harvest. At that time, Park Ki-soon, famous as the land king, took charge of the established chairman of the railroad installation and established it, and with the establishment of Samrye Station, the access road was connected to his farm. In addition, a new road was built on the farm land that owned the Hujeong-ri area to the Seoul-Mokpo Interroad in Samrye-ri, thereby expanding the urban space. In other words, unlike Gunsan and Iksan, which were built under the leadership of the Japanese colonial eran government, the urban space in Samrye area was expanded by a farmer who grew up as a large landowner based on agriculture, which was the economic base at the time.

Two dominant components of polar motion are the Chandler and the annual components. Recently, the existence of 500-day period component in the Earth's polar motion has been manifested. But its existence is not clear on Fourier spectrum. One cause of difficulty involved here is that the amplitudes of the two main components are slightly variable in time by certain amounts (Chandler: 0.15~0.28 arcsec, annual: 0.09~0.15 arcsec). A residual polar motion time series excluding the two main components for a time span between 1962 Jan and 2010 Nov from IERS C04 time series dataset was constructed by least square fitting. For faithful fitting, 43 time segments of 6.8 year length (each starts on January 1st of successive years) were separately acquired and later combined together. The period of dominant peak in the spectrum of this residual polar motion time series is 490 days. Next peaks have their periods as semi-annual, 300~330 days, ~560 days, 670 days, and 1360 days.

The main purpose of this study is to reveal the properties and specialities of architectural space after Modernism. Space was the main theme of Modernity in architecture and they insist Modern architectural space had its own characteristics compared with the earlier period. With view that another paradigm of space is rising as a criticism of and departure from Modernity, this study try to show what is the contents of difference and how it express in reality. We can find a new trends in architectural spaces, that are the production of totally different circumstantial background as like information society, digital media environment, post structuralism, new science and heterotopian situation in urbanism. We can call it Post Modernity in architectural space that would find the 'Otheness' and expand the territory of architecture. It means not only the change of architectural space itself but also different cognition and perception of space is taking place. Contemporaru architectural space has lost its materiality and conventional socio-cultural functions. Dematerialization and media or image -like being is the new characteristics instead. It demands a new way of being in a different life-world as well as the new expenence of architecture.

This study aims to define concepts on Hospital Design Focused on System to respond to the development and change by comparing general design methods of the General hospital architecture in Korea and analyze elements suitable to concepts on Hospital Design Focused on System in the General hospital architecture through examining the transformation of General hospitals in Korea. Essential architectural elements composing the Hospital Design Focused on System are as follows. First of all, the elements which can react to development of hospital architecture are HOSPITAL STREET and site situation. Secondly, core, equipment shaft, column, MAIN STREET and air handling unit room are elements of great importance as the location of these elements determines the dimensions and scale of the space which hospital functions are assigned to. Third, the area in regard to the rate of change is formed by MAIN STREET, which is the primary element, and envelope. The depth between MAIN STREET and envelope is defined as space depth. The flexible area is determined depending on this space depth and thus how to set up this flexible area determines the degree of readiness in responding to the change.

This study has main purpose to understand and interpret the house Nok-U-dang, an upper class built in Chosun dynasty, not by outsider researcher's view but insider dweller's view. To interpret correctly, dweller's everyday life in the space and form is examined on a microscale beyond the physical space and form of the house, main object of architectural history To understand the present form exactly, the study restore traditional life in past era, 1940s. Main method of restoration is the ethnographic interview, based on cultural anthropology. Like any other upper-class house, the house has been influenced under ruling Confucian ideology in Chosun dynasty: separation of man's and woman's quarters and hierachical arrangement by generation, and worshipping ceremony for ancestor. However, it is by practical management for agricultural production that every court and building of the Noku-Dang can be explained correctly; preparing seed for sowing, tool storing, preparing and serving meal for laborers, making manure, harvesting, threshing grain, storing grain and so on. Precedent studies interpreted the house by the Confucian principle too much and made conclusion of dignity and austerity of ritual: woman's quarter, is closed and serene space. However this study shows that the space is semi-opened and composite space by agricultural works. And the Sarangchae, master's quarter, is located properly at visual center to control every agricultural activity.

In the present paper, we treat a Finsler space with a special (${\alpha},\;{\beta}$)-metric $L({\alpha},\;{\beta})\;\;C_1{\alpha}＋C_2{\beta}+{\alpha}^2/{\beta}$ satisfying some conditions. We find a condition that a Finsler space with a special (${\alpha},\;{\beta}$)-metric be a Berwald space. Then it is shown that if a two-dimensional Finsler space with a special (${\alpha},\;{\beta}$)-metric is a Landsberg space, then it is a Berwald space.

This study is to inspect and analyse the historical background, spacial organization and architectural features about the traditional government office building of Gangwon Gamyoung(the supreme local government office of Gangwondo in Chosun dynasty). The results are as follows. - Gangwon Gamyoung was located at the center of Gangwondo in consideration of distance to each small local office. And also it was located in consideration of geographical connection between Hanseong(today's Seoul). - The spatial organization of Gamyoung was divided into the three parts of entrance space, government office building space and backyard space. The entrance space was composed of three gates(Pojungru-Jungsammun-Naesammun). The government office building Space was consisted of business and living building as center of Sunhwadang(the main office building). And the backyard space was composed of Yonji(pond), Jungja(bower), and so on - The way to enter the space of Gamyoung follows the order from Pojungru(the first & outer main gate with a bower), Jungsammun(the second & intermediate gate), Naesammun(the third & inner gate) to Sunhwadang at last. - There were a beautiful Yonji(pond) which to be rectangular type and to have a round island with Bongraegak(bower) at Gamyoung backyard, the drain conduit and pedestrian road covered with pebble in the ground.
