These days, beds have been developed not as furniture to sleep in but Healthcare Furniture. The function of heating, non-electronic-waves and far-infrared rays have been added. Also, eco-friendly materials such as stone, mud, rubber and wood are combined to them together with the radiation-heating method using heat conduction through electronic coil and hot water circulation. Modern people suffer from stress and fatigue. The hot issue is "health." Focused on the health, the development of design for beds considering the influence electronic waves, anions, deep sleep and the density of toxic materials have on human bodies has become urgent. In this study, the trend, specification and efficiency of the functional health-related electronic coil technology are analyzed. Through the analysis, the environmental standards are set. According to them, technology, eco-friendly materials and additional functions for the development of the design are considered. Also, the government is promoting the IEC international standardization for the Korean traditional floor heating style beds. In preparation for that, we adopted new HPT method technology. It enables non-electronic-waves, low electricity and stable temperature maintenance control for the warm top and the cool bottom. Also, the head boards and the frames of the beds can be separated. Through this separation, the beds can be easily moved or installed. Eco-friendly materials such as Hinoki cypress wood and red clay and the existing tables function are combined to the head boards so they can be used as drawers and display shelves. If they are used as separate items, they can be used as covers. This is how we suggest the design for the heating beds.

This study analyzed the domestic and foreign cases of the existing smart home service and grasped the needs of the future smart home service in the future of the Internet of Things. As with all smart homes, the effectiveness of future use is important when comparing needs and random services according to user usability and destination patterns. In order to improve the reliability and to promote the development direction, we conducted a questionnaire survey of 110 people in 20 ~ 30 age group. The survey shows that the reliability of the smart home service is low. The low trust factors include: 1. lack of usability; 2. lack of device recognition; 3. lack of specialization services. Since the smart home service is still in the early stage, various smart home services and ecosystem should be constructed according to user's needs.

This study conducts empirical research on gender differentials of economic resources in old age. The economic resources are assessed by the presence of independent income source and the amount of total income. The study, based on nation-wide survey of the elderly, examines the effects of individual level variables and household level ones. Also, it compares such effects between male and female elderly. The analysis shows that several variables have gender specific effects. Among them, particularly interesting and important are marital status and coresidence with children. The positive effect of having spouse is greater among female elderly than among male elderly. Also, while coresidence with children among male elderly has insignificant or slightly positive relation to their own economic resources, it has a negative relation among female elderly. These results indicate that female elderly are dependent on their husbands and children. The study suggests that future research on the elderly incorporate gender differentials into models attempting to capture diversity within the elderly population.

Recently, people are spending a lot of time inside their homes because of various diseases. It is difficult to ask others for help in the case of a single-person household that is injured in the house or infected with a disease and needs help from others. In this study, an algorithm is proposed to detect emergency event, which are situations in which single-person households need help from others, such as injuries or disease infections, in their homes. It proposes vision pattern detection algorithms using home CCTVs, audio pattern detection algorithms using artificial intelligence speakers, activity pattern detection algorithms using acceleration sensors in smartphones, and dust pattern detection algorithms using air purifiers. However, if it is difficult to use due to security issues of home CCTVs, it proposes a fusion method combining audio, activity and dust pattern sensors. Each algorithm collected data through YouTube and experiments to measure accuracy.

We have focused on the roof construction method of Urban Hanok in Bukchon, Seoul. The Urban Hanok, urban traditional housing type, had been evolved In modern context from 1930's to 1960's. We have confused Urban Hanok with traditional Hanok, because they have similar figures. But Urban Hanok have the characteristics as a result of the roof construction method. The purpose of this paper is to define Urban Hanok more concretely, thus we payed attention to the roof structure, specially to the comer that each roof structure meets. So we got some characteristics of the roof construction method of Urban Hanok in Bukchon. First, the roof construction methods of the roof are transformed at the corner parts, where three purlin structure and five purlin structure meet. The collision of the different roof structure has made a lot of types. Second, the roof slope of Urban Hanok is more gentle than traditional Hanok, that is caused by ornamental double eaves and awnings. Finally these characteristics are results of the compact lot size in urban neighborhood. The construction method is a inclusive word that contain materials, composition, ornament and social common sense. With the understanding on the roof construction method of Urban Hanok, we can define the identity and the value of Urban Hanok, And we can suggest the policy and the design guidelines for the reservation and rehabilitation for Urban Hanok of Bukchon, Seoul.

A major barrier to the spread and vitalization of renewable energy lies in its economic infeasibility. And yet, there is a disparity in estimating the economic feasibility between supply and demand sides. Taking this into account, we calculate an appropriate level of mini-solar panel subsidies provided by the Seoul metropolitan government. More pointedly, this research investigates the receptivity and social equity of the subsidy program based on the analysis of the program's financial feasibility. The results show that the subsidies can have anticipated effects for the heavy electricity consumption group but not for the low electricity consumption group. Specifically, estimated pay-back periods for groups of 401kWh ~ 500kWh (per month) users, 201 kWh ~ 400kWh users and 101kWh ~ 200kWh were approximately 5years, 8 ~ 9 years and 12 years, respectively. This implies that differential scales of the subsidies can better contribute to reducing regressive difference between the groups and meeting the goal of social equity in regards to energy justice.

Annual total values and thereby assets values of natural resources are determined by sample household WTP estimates and the extent of market. In the current domestic practice of CVM, total numbers of national households were used as the target population to measure total economic values including non-use values. This study proposed an alternative method of calculating potential user groups based on distributions of residential area of visitors in the sample using 4 provincial parks in the Chon Buk area as cases. The sample mean of WTP of Moak Mt. visitors, who are mostly from the nearby Chon Buk provincial area, was estimated to be about 8,215 won. On the other hand, the mean of WTP of Sun Woon Mt., whose visitors are evenly distributed from all over the country, was about 4,693 won. When applied national households as the target population, annual total benefits and thereby asset values of Moak Mt. was high enough to be 86 billion and 1.6 trillion won respectively. However, those of Sun Woon Mt. was low to be 52 billion and 1 trillion. On the contrary, when applied potential user groups of each park as the extent of market, annual total benefits and asset values of Sun Woon Mt. was reversed to be high--23 billion won and 400 billion won respectively. However, those of Moak Mt. was lowered to be 10 billion won and 200 billion won. Furthermore, asset values of the same park were differed by 2 to 8 times according to the way of setting the extent of market.
