The construction period of the ondol (Korean floor heating system) at Hoeamsa Temple Site is known as Joseon. The main reason is that a large number of remains in the Joseon era were excavated from the ondol floor with an all-around ondol method. This article partially accepts the theory of the creation of Ondol at Hoeamsa Temple Site during the Joseon Dynasty and suggests a new argument that some Ondol remains were built during the Goryeo Dynasty. The grounds for them are as follows. First, through the building sites consistent with the arrangement of the Cheonbosan Hoeamsa Sujogi (天寶山檜 巖寺修造記, Record of Repair and Construction of Hoeamsa at Cheonbosan Mountain), it is highly likely that the ondol remains as a basic floor was maintained during the reconstruction period in Goryeo. Second, the all-around ondol method of the Monastery Site has already been widely used since the Goryeo Dynasty. Third, some ondol remains consist of "Mingaejari" and "Dunbeonggaejari," which were the methods of the gaejari (which dug deeper and stayed in the smoke) in the pre-Joseon Dynasty. Based on the above evidence, this study argues that the building sites such as Dongbangjangji, Seobangjangji, Ipsilyoji, Sijaeyoji, Susewaryoji, Seogiyoji, Seoseungdangji, Jijangryoji, and Hyanghwaryoji were constructed during the late Goryeo Dynasty.

As a result of reviewing various documents and existing researches, since the late Goryeo period, the most active period in the Ondol(溫突, Korean floor heating system) facilities is the 17th century. The phenomenological reason was recovering the buildings destroyed by the Japanese Invasion of Korea in 1592(壬辰倭亂]) & the Manchu War of 1636(丙子胡亂), but the underlying cause was an abnormal climate in which a pair of summer and winter cold continued. In the 17th century, as the Ondol facilities grew rapidly without distinction between regions and classes, the supply and demand of fuel caused economic and natural environmental problems. And a negative and positive view on Ondol was suggested. Since the middle of the 18th century, when the demand and supply of Ondol reached its peak, which could no longer increase, a new awareness of Ondol began to grow. The room was called the Panbang(板房)and the Ondol, depending on the material that made up the floor. It was considered natural to have the Ondol from this time on. The Incan(□火間) and Jo(竈) that were made to burn were started to be recorded as a kitchen, regardless of size and function. Changes in social awareness of Ondol have led to concerns about heating efficiency. A variety of architectural explorations were conducted. Such a search was later realized in concrete architectural form. There is a double Ondoll structure, and the column spacing is reduced compared to the previous one. The heat buffer space is formed around the Ondol room, and the double window can control the light and the air going in and out.

In Hanoks which are Korean traditional houses, gudeuls (ondols) are more important than other elements. Recently, demand for Hanoks has been rapidly increasing thanks to the effects of Korean waves and rediscovery of traditions. This paper traced the process of development of gudeul construction technology to examine the definitions of terns and changes in the types of gudeuls and discussed the prospect of future gudeul construction technology.

Gudul is a traditional heating system which was created by our ancestors. This study is focused to the developments of new flooring material through the physical and chemical analyses of the Gudul rocks. The study proceeded with selecting the theme and study areas, sampling, geological survey, several analyses of the rocks, development of new floor material (a kind of porcelain). Gudul rocks are sampled from a total of twenty one cities and counties are assigned to nine tuffs, five quartz porphyries, four gneisses and three schists in rock type. From the geological study, these rocks are very similar to ones in surrounding areas. Comparing Gudul rocks to others not used in Ondol, Gudul rocks show low densities, higher porosities and brittle features. Analyzed in thermal properties, the rocks are lower in conductivity but higher in conservation and resistance in the aspects of the properties. Considering mutual relations between thermal properties and chemistries of the rocks, conservative characteristics are proportional to MgO contents but not to SiO2. In particular, minute quartz grains in the rocks were gradually cracked and rejected under torch flames. Those features may indicate that quartz grains are closely related with the thermal resistances of the rocks. On the basis of above rock characteristics, new flooring material was made. The material includes the mixed states of amphibolite sludges with high MgO contents and white china soils (bearing kaolinte). Then, the material was tested in the above thermal properties under the variable mixed ratios. At the results, 4:6 (sludge : soil) ratio was the most excellent among above tested materials. So, the textiles used in architecture and the electric heating cushion and the mugcups were produced as test goods.

A MOCS(Mobile Ondol heating Control System) is designed for the context-aware inference and the control of the device using mobile phone. The MOCS prepares indoor thermal environments and corresponds to the situation like resident’s coming home. Ondol Heater can be controlled as if the resident came home already. The MOCS adopts direct or indirect awareness of context in housing environment. In this research, it deals with the system making up with agent control module for the direct control and DBMS including the inference for the indirect control. Agent control module is made up of MainServer module for receiving control command and HomeAgent module that operates transmission and receiver by USN(Ubiquitous Sensor Network) device. DBMS consists of the event log data and the control log data including various databases. The structure of database has systemic information using the hierarchy of physical and electronic context for the inference. Furthermore, we suggest and implement what to provide, control and manage the home service in the mobile environment. Finally, it is expected to embody the ubiquitous housing and apply an ondol heating system communicating between human and home at anytime and in anyplace.

Ondol is the unique traditional heating system of Korea, which is excellent in thermal comfort. Whereas it has several merits as a wet construction method, its work process is complicated and disadvantageous in protecting noise and has concrete heat storage layer. So it is necessary to develop a new material to cover these demerits. In this research the material that can resolve the problems of construction and noise prevention while keeping heating function of existing wet floor structure has been developed through manufacturing artificial wooden floor panel utilizing waste tires. The developing tendency of existing floor structure companies was studied for experimental contents, and through testing of manufactured materials' degree of strength of bending and pressure the function and similarity of natural wooden material could be confirmed. These floor structure can be shortened of its construction period through simple method which results in saving construction cost and convenience of maintenance, and especially it can be said that as 70~80% of its material is powder of waste tires, it has excellent function against floor impact noise and it utilizes recycling material more than anything. It is likely that through more tests and research, the construction method for linking part between panels which hasn't been dealt with in this research will be improved.
