Houses have usually been planned for those who are in good physical condition rather than with disabilities. Therefore, it is difficult to provide a high quality residential environment for people with disabilities. To live in their own houses continuously, it is essential to renovate their houses where they have been living. This study focuses on removing the barrier factors from houses by analyzing the characteristics of disability types and purpose of each space. Therefore, this study divides a house into 5 sectors: an accessible path; an entrance hall; a corridor; a living room; and a bedroom to remove the barrier factors from each sector according to the analysis above. As a result, the sectors that show high frequency and importance of renovation should be considered as a top priority for renovation.

In this study, we assumed the kitchen fire raising the highest fire rate in apt. and analyzed the fire risk to use CFD in order to estimate the problem of evacuation equipment and the fire vulnerability of 16 or fewer storey apartment. Fire occurring in the kitchen is expended to the livingroom and other rooms. We analyzed that the temperature effected by heat was more than $60^{\circ}C$ after 90 sec in the entrance of apartment unit. If fire is early recognized by men and men don't escape in time, it have too huge demage to block the exit. When the evacuation equipment suggested in this study was installed in order to solve the problem of evacuation equipment, we analyzed that it was estimated more than safe in safety evaluation by heat and heat flux.

Sprinkler installations shall be operated at normal operating temperature of the atmosphere as a fire sprinkler head in any facility to control and extinguish the fire when the fire initially. Recently, however, some flush type quick response automatic sprinkler heads in slow fire place is a problem that can not be normal operation are raised. In this paper, by using the experimental model of the Apartment house of Commons and Cabinet burner size bedrooms fire conditions to form a slow growth rate and can supply more than 0.2 MPa pressure is the minimum pressure that can be applied inside the pipe in the field experiment was conducted. In the majority of experiments lush type quick response automatic sprinkler heads which is used in the country it was confirmed to be incompletely opened as the Cold Soldering occur. This phenomenon is likely to fail early fire suppression and control because they can cause the spread of fire and casualties needed to complement domestic product testing and type approval standards through additional research.

The possibility to development of floor vibration problem is larger in case of long span structure under service loads. Therefore, to improve the vibration performance of the floor, increasing of its thickness is a common method. But, increasing of thickness can lead to increase of slab self weight and reduce the effectiveness of the building. For this reason, attention for voided slab which reduces the self-weight is increasing. Hence, voided deck slab combined with deck plate and polystyrene void foam which has buoyancy prevention capacity and much developed construct ability has bee developed. By using the developed voided slab, vibration performance of a mock-up building structure has been investigated in the current study. The results according to analysis showed that they can be implemented in living and bedroom which are considered as 1st grade on the basis of "Residential Evaluation Guidelines for Vibration of Buildings" by the Architectural Institute of Japan.

Recent decreased number of family members have caused at least one spare room which is not used as a bedroom in an apartment house. In addition, people who need an apartment house cannot be satisfied with the typical unit plan any more, and rather request more various types of living space. Based on this kind of housing needs trend, we would like to analyze and classify dwelling unit planning methods which may create particular purpose extra rooms to satisfy their unique needs and to give characteristics and individualities by means of study on various cases. As a result of this study, we could find the following planning methods which can produce extra rooms : 1) Utilization of optional plan between living room and adjacent bedrooms, 2) Utilization of optional plan on master bedroom zone, 3) Insertion of transitional space and Utilization of spare space, 4) Insertion of a space for housewives near a kitchen, 5) Positive utilization of a balcony space. This study is also trying to show many unit plan cases of which planning methods can be applied in other cases.

This study compares the space depth and layout of a modern apartment floor plan (MAFP) and the standard floor plan of traditional Korean houses (STKHs), which has preserved the traditional beauty of Korea. Space Syntax was applied to compare the MAFP and STKH. The space within MAFP was more divided into many spaces than the STKH. In both types of floor plans, the living room space had the highest degree of integration and was used for central functions in the each floor plan. The STKH and the space in the MAFP have more segregated space than integrated space. In the STKH, the master bedroom and other rooms were found to be segregated space. However, the master bedroom of the MAFP was highly integrated space. The function of the thet maru has been greatly reduced in the STKH, and the numaru was classified as a highly segregated space. The evacuation space was the most segregated space in the MAFP. The STKH has been adapted and changed according to the trends of the times, and the MAFP reflects our traditional living habits.

The artificial intelligence speaker market is in a new age of mounting displays. This study aimed to analyze the difference of experience using artificial intelligent speakers in terms of usage context, according to the presence or absence of displays. This was achieved by using semantic network analysis to determine how the online review texts of Amazon Echo Show and Echo Plus consisted of different UX issues with structural differences. Based on the physical context and the social context of the user experience, the ego network was constructed to draw out major issues. Results of the analysis show that users' expectation gap is generated according to the display presence, which can lead to negative experiences. Also, it was confirmed that the Multimodal interface is more utilized in the kitchen than in the bedroom, and can contribute to the activation of communication among family members. Based on these findings, we propose a user experience strategy to be considered in display type speakers to be launched in Korea in the future.

In our daily life, quality of sleeping is closely related to happiness index. Whether or not people perceive sleep disturbance as a chronic disease, people complain of many difficulties, and in their daily life, they often experience difficulty breathing during sleep. It is very important to automatically recognize breathing-related disorders during a sleep, but it is very difficult in reality. To solve this problem, this paper proposes a mobile-based non-contact sleeping monitoring for health management at home. Respiratory signals during the sleep are collected by using the sound sensor of the smartphone, the characteristics of the signals are extracted, and the frequency, amplitude, respiration rate, and pattern of respiration are analyzed. Although mobile health does not solve all problems, it aims at early detection and continuous management of individual health conditions, and shows the possibility of monitoring physiological data such as respiration during the sleep without additional sensors with a smartphone in the bedroom of an ordinary home.
