The ondol is a uniquely Korean system of providing warmth to room. The ondol rooms never use daily life furniture because the ondol warms the floor surface where people sit. Finally, the ondol floor changed the traditional housings inner space. Before use ondol where daily life furnitures[sang(상) and Tap(탑)] are installed in the room. The origin of daily life furnitures are the ancient tomb mural of Koguryo Period. The daily life furniture can be classified as three large groups in the ancient tomb mural of Koguryo. First, a single seat[Jowa-sang(좌상)] of set up a screen[병풍]. The second, It make possible Many peoples take a seat with no decoration seat[Tap(탑)]. The third, uptodately table and chairs. A radical difference between sang(상) and Tap(탑) whether set up a screen[병풍]. The meaning of sang(상) and Tap(탑) in Koguryo ancient tomb provided Oksa-jo[옥사조] in Samkuk-sagi[삼국사기] with several valuable leads to help solve the sang(상)'s meaning. Furthermore, It will be start ponit of study on constructive shape of inner space in those days.

When a building is planned and designed, the design should be able to minimize the cost during the whole life cycle of the building. This study has begun to analyze LCC about the alternative design which is applicable to renewable energy facility construction. It is reviewed domestic and foreign papers about the trend of LCC technology and it is determined the analytical method to analyze the LCC of renewable energy. Regarding the review of alternatives, it is chosen the three alternatives which are able to designed combing the renewable energy facilities and it is performed the LCC analysis about each alternative. Alternative 1 is Photovoltaic + Solar Thermal + Photovoltaic /Wind Power, Alternative 2 is Geothermal + Photovoltaic, and Alternative 3 is Photovoltaic + Solar Thermal. The LCC analysis is present value method, its analytical period is 40 years and it is applied 3.2% of real discount rate. As a result, it is proved that Alternative 1 and Alternative 3 are not able to collectible the early investment cost during the analytical period and Alternative 2 is analyzed that its pay-back period of early investment cost is about 31 years. As the final outcome of this study on case analysis, it is more advantageous to use the combination of Geothermal and Photovoltaic energy than to use the other combination in LCC aspect.

Superframe in IEEE 802.15.4 Standard is subdivided into an active period and an inactive period to reduce energy consumption. But communication nodes use same data transmission range in an active period, thus communication nodes spend a lot of energy to send data another nodes. In this paper, we proposed reduce energy consumption algorithm that nodes use different transmission power. Cordinator split transmission area into four group and transmit becon message to nodes. Nodes adjust transmission power according to becon message and wates lowe energy than normal nodes. We proposed energy-efficient cross layer protocol that have different PAN (Personal Area Network) by four range group.

This article analyzes the publicness of early modern cities and the character of samurai residences as urban dwellers through the water supply and use of the Edo period in Japan. Firstly, in Edo, a megacity with a population of about one million, the Shogunate organized samurai residences (mainly those of feudal lords, Daimyo) into geographical organizations, and samurai residences paid for the repair of water facility and the water fee, just the same as the townspeople. Next, in Fukui (provincial castle town), samurai residence (Daimyo's vassal) organization for waterway didn't exist. The samurai residences were relieved of the burden of maintaining the waterways due to poverty. And, before the later Edo period, samurai vassals were not punished for violating the rules on water use, but they were eventually included in the punishment. The gap in feudal status between samurai and townspeople narrowed. It was a process of creating a modern urban society composed of equal dwellers. Although Edo and Fukui belonged to the same category as castle towns, the urban publicness and the position of samurai residences were different due to their dissimilar political positions as the Shogunate capital city and the Daimyo's provincial castle town.

The purpose of this research is to analyze the differences between literature (Belles-letters) class in DDC 19 and literature class in KDC 3. The results of the study can be summarized as follows : 1. The section of philosophy and theory of literature in DDC was subdivided according to the properties as including subsection of theory of criticism but KDC didn't subdivide this section. 2. In DDC, the subsections of 'rhetoric in specific languages' and 'rhetoric of specific kinds of composition' in rhetoric section was established and can subdivide according to each languages and subjects. These considerations can be useful as compared with KDC. 3. In DDC, collections or criticism of several literatures in specific forms can be more subdivide according to specific aspects or features dealing with in the collections or criticism by a n.0, pplying Table 3-A when specified more than the literary form. 4. Reviewing a notational rank to be assigned in literatures of specific languages, Latin literature and Classical Greek literature to be ranked in division in DDC was established as subsection in KDC to treat them as literatures of minor languages. 5. The DDC can sometimes a n.0, pply, in literatures of all languages, the notations of Table 3 to be subdivided again as specific kinds of literary forms, but KDC subdivided literary forms as specific kinds of each forms in only Korean, Chinese, Japanese literature. 6. In DDC, even literatures of minor languages are provided with 'the period table for the specific literature' under each literature of specific languages in schedules and these period tables can be a n.0, pplied a n.0, ppropriately, but period numbers in KDC was established in only Korean, Chinese, Japanese literature. 7. The optional use of letter prefixes or special numbers such as 828.99 to distinguish literatures of countries other than the "mother country" which makes the use of period tables feasible, but the KDC can only use to distinguish without the function of dividing a period such as DDC. 8. According to a n.0, pplying Table 3 and 3-A also in literatures of specific languages(810-890), a literature of specific languages, a specific literary form in literature of specific languages and a literature or literary form of specific period, in case of a n.0, pplying 'form divisions 08-09', can subdivide again by a specific aspect or feature dealing with in the works when specified. 9. For grasping the rate of subdividing, after selecting several sample-titles in literary field, they classified by DDC and KDC and gave a definite score in accordance with analytic small subjects. According to the results, the rate of subdividing in literature class of KDC is proved as less 22.8% than DDC. than DDC.

This is a study of discourses on the family used during the Enlightenment period in Korea. To this end, 1 have conducted a qualitative analysis of the editorials taken from the Taehan Maeil Sinbo of that period. The major findings are as follows: First, these Enlightenment period discourses claimed that civilized nations evolved from a family in primitive society. This concept of family is different from the concept of family in a Confucian society. Civilized societies believed the family is less important than the nation. At that time, Korean Press used the term bumoguk (Parental nation) to refer to the nation in an attempt to equate national loyalty to filial piety. Second, the Enlightenment period claimed that the nation belonged in the Public sphere while the family belonged in the private sphere. However, it was stated that it was the duty of the family to discipline the members and make them into good citizens. Finally, Enlightenment discourses used familyism as the basis of their arguments.

Damage to high-rise buildings caused by earthquakes is less frequency due to small distribution of high-rise buildings and low transmissibility of seismic motion to high-rise buildings. However, demand for high-rise buildings is increasing for development of construction technology and efficient land use. In addition, if high-rise buildings are constructed on soft ground such as landfill, transmissibility of seismic motion due to long-periodization of seismic waves is likely to increase. Thus, with development of technology, buildings are required to expand range of seismic design such as safety for long-period seismic waves. Therefore, in this study, dynamic experiments were performed to evaluate response characteristics of high-rise buildings according to period characteristics of seismicwaves and time history analysis was performed to verify them.

In this paper, the estimation of the structure of a logic circuit under test is made from the observation of the input-output correlation function by use of M-sequence, from which we can estimate whether or not any fault exist in the logic circuit. Especially, investigation was made in case of the 2_stage logic circuit. We checked theoretically the sequence of correlation function, and we have shown that the correlation function is a function of period of M-sequence only, land the appearing number of correlation function in a period is a constant value depending on the logic circuit only. And by computer simulations we have shown that the structure of the circuit under test can be estimated from the observation of sequence of correlation function.
