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.

Human races have used various heating methods, since fire was founded in the world. It is very the important work to trace the history of Ondol, which originated and developed in the Korean peninsula. Especially, the study on ancient Ondol would contribute to improving the present heating methods and predicting future ones. In this paper, we shall study through the analysis of documents such as oriental ancient documents, the document of Choseon dynasty, Europe documents and American documents. In order to discover the origins of Ondol as one of the excellent heating method all over the world, This study aims at identifying the history of Ondol and characteristics in the Korean peninsula, through document analysis. Results of this study are as follows. 1) The first record about Ondol is related to Ondol at Kwankyesa in the border land between Gogooryo and the northeast of China. 2) Ondol built in the period of Balhae dynasty had single flue(Hanjool Gorae) and double flue(Doojool Gorae). 3) The overspreading of Ondol made the quality of Ondol poor in the last of Choseon dynasty. 4) If the layout of Bulmok had been poor, it might have caused the backflow of fire. 5) Korean Ondol has been used as a heating method for a long time and the period is longer than that of the west.

This paper introduces the basic classification of Ondol, the number and form of main entrance, distribution as a basis for classification. And it introduces the various practices and structural characteristics of Ondol. Details are introduced in various forms Ondol of the working principle. In the paper, it also did a more detailed exposition for some of the concepts right.

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.

This paper describes the traditional Ondol medical care, the specific combination of ancient and contemporary examples to be articulated. As a traditional Korean culture, to be extracted from the historical perspective, it described the relationship and origins between them, From a health perspective, in accordance with the logic and pharmacologyit introduced Ondol as the important principle of health care equipment. The modern architecture of some common harmful to the body, from the perspective of Ondol, it should be improved and based on scientific proof to the theory.

This study is for analyzing a house and underfloor heating systems called gudle of Korean Chinese, Manchurian and Chinese that are located in the northeast China, which is north of Korean peninsula. Thus it has the similarity and difference among the form of gudle of each folks. The basic form of gudle in Manchurian area of China differs and falls into four categories: U-shaped kang, L-shaped kang, /-shaped kang and whole gudle(gudle that is composed of the whole place). In case of U-shaped kang, it is a basic form of Manchurian and designed for protecting cold weather in northeast area. U-shaped kang has a long space that can be heated so that it enables as many as family members to sleep. It has the advantage of making the best use of space. The form of Chinese is /-shaped kang. As Chinese has traditionally lifestyle of chair sitting culture, so it has the form of tonggudle, or a room equipped with gudle unlike yoegudle that a fire was made under a stone like goindoel and is suitable for lifestyle of chair sitting culture. As for the kang of Korean Chinese, it is called gudle and has the largest in width compared with that of Manchurian and Chinese. Also, the height of gudle is much lower than other houses by about 30~40cm because Korean Chinese have been living "floor sitting culture"on gudle, which means the tradition of removing one's shoes before entering and sitting on the floor, while other folks like Manchurian has lifestyle of "chair sitting culture". Therefore the study found out that the folk housing of each tribe in the northeast China has similarity and difference at the same time. In particular, the form and size of gudle(kang) varies depending on the way of life.

This study is to develop the new type of environmentally friendly Ondol system for improvement of energy efficiency, improvement of impact sound insulation of floors and reduction of material & resources in apartment houses. The prototypes for development of the Environmentally Friendly Ondol System of Double layer (E02 System) are designed and are made as the manufactures in order to improve energy efficiency & the impact sound insulation of floors and reduce material & resources in apartment houses. The performance measurement of impact sound insulation of floors is tested. and the performance on the E02 System is compared with the existing Ondol system. As a result, the impact sound insulation of floors of the E02 System is improved more 15 dB than standard level. The E02 System got the first grade Certificate on the impact sound insulation of floors. The performance of thermal insulation and energy efficiency is compared the E02 System with the existing Ondol system. The E02 System is evaluated as more 9% of energy efficiency than the existing Ondol system. The component weight per area of the E02 system is 96 kglm', and it is evaluated as reduction of the existing structure weight. Therefore the E02 system will be utilized as solution for pending problems in apartment houses in Korea.

As we all know Ondol has been the most efficient and comfortable heating system of the rural residence in the Northeast of China for hundreds of years. But recently, through field survey, it was found that some country people replace the Ondol with homemade heating blindly. The result of this replacement is that heating effect of residence in winter is worse. And at the same time, it aggravates air pollution and increases heating payout. According to our real situation of energy sources reserve, environmental pollution and economic income of rural people, it is not only inpractical but also unreasonable, that in the northeast of China Ondol is replaced by homemade heating completely in winter. Ondol has its unique heating and hygienic efficacy. And it stands for cultural tradition and life custom of the country's cold areas. So we should improve Ondol combining resident structure and material. And it can make the Ondol system flourish with vigor and promote sustainable development of the country's traditional Ondol residence.

Gudul has been used since it was invented, and will be used continuously. But recently, we used rarely. One of the this reason is unequally floor temperature in Gudle because the distribution of heating air is not constant. So flow field in Gudul must be known for uniform temperature in floor. Recently, many fluid engineer have been performed the numerical analysis for the understanding of thermal and flow field based on the development of CFD(Computational Fluid Dynamics). In this paper, to find out the variation of temporal temperature in floor of traditional Gudle, we have performed numerical analysis. Initial temperature in floor is 20 t:' after 880 seconds later, maximum temperature become 2i.Oi t:'. ihour later, maximum temperature in floor become 34.5 t:' because continuously increase from 880 seconds.

When processing with wood floor covering on wet ondol floor, there are frequent defects caused by floor condensation, floor loosening, lowering of adhesiveness, wood contraction and swelling. The working method is still conventional with problems of lower indoor heating efficiency. Accordingly, ordinary wood floor covering is too expensive without any special functions or features, and it is necessary to suggest reasonable solutions or methods.

This study is regarding the property evaluation of mortar for ‘ONDOL’ floor (Korean floor heating system) finishing with reduced drying and shrinking properties to use it in the form of ready-mixed concrete mortar. The mortar utilized furnace slag based inorganic binding agent NSB, which has the characteristic of CaO included in HCFA generated from the fluidized-bed-firing power plant. Based on the test results, it is judged that mortar for ‘ONDOL’ floor finishing based on NSB including HCFA can be used in the form of ready-mixed concrete. According to site test construction, the flow property was relatively poor because fine gravel at ready-mixed concrete factory was used. However, since finishing property, crack resistance and water content are good, it is believed that it can be used at construction site in the form of ready-mixed concrete mortar. More study on adhesion property with floor plate would be required in the future.
