In recent years, the number of single-person elderly households has increased, but when an emergency situation occurs inside the house in the case of single-person households, it is difficult to inform the outside world. Various smart home solutions have been proposed to detect emergency situations in single-person households, but it is difficult to use video media such as home CCTV, which has problems in the privacy area. Furthermore, if only a single sensor is used to analyze the abnormal situation of the elderly in the house, accurate situational analysis is limited due to the constraint of data amount. In this paper, therefore, we propose an algorithm of abnormal situation detection fusion inside the house by fusing 2DLiDAR, dust, and voice sensors, which are closely related to everyday life while protecting privacy, based on their correlations. Moreover, this paper proves the algorithm's reliability through data collected in a real-world environment. Adnormal situations that are detectable and undetectable by the proposed algorithm are presented. This study focuses on the detection of adnormal situations in the house and will be helpful in the lives of single-household users.

This study was conducted to examine housing preferences among single-person households and to propose guidelines for housing design choices for single people. One hundred and sixty responses to the questionnaire developed by this researcher were analyzed utilizing frequencies, percentages, and t-tests. There were significant differences between single households and non-single households in various aspects of housing preferences. Differences were found in the desired type and size of housing, needed amount of space, and the importance of space itself. Single persons wanted to live in a small apartment, about 83.45$m^2$ (25.29 pyung) size. They consider the bathroom and the master bedroom more important than the living room and kitchen. They prefer to have specifically function-oriented rooms such as shower, home office, computer room, exercise room, or leisure space. Single persons consider information-technological facilities within an apartment very important. They would like to adopt automatic and electronic technology in the house, such as optical communication network, automatic air-cleaning system, and internet TV. Housing preferences differ significantly according to socio-demographic variables such as gender and age. I propose in this study a small-sized, information-, high-tech- and leisure-oriented design that corresponds with the actual housing preferences of the single-person households.

Recently, Korean society is increaseing "1 person family" phenomenon, which is influenced by changing of young peoples' value, aging society and social economic problems. Increase of single households is a result of complex economic, cultural and social factors. It is because as the individual's financial independence increases due to elevated income and education level, the age of marriage is going up and the individualism, which values the individual's value rather than custom, is spreading. Therefore, this new phenomenon will be impact to between social, economic value structure and living space. An increase with small furnitures are also increasing of R&D and marketing plans for 1 person family. Currently, 1 person family is bigger than last decade and that is requiring more suitable and multi-functional furniture for them. However, in Korea furniture companies are more optimization to traditional family size. Thus, this research explore about developing cheap price sofa bed, which is using at narrow area and small place.

Objectives: This study examined the dietary characteristics and needs for community kitchens among young adults of single-person households in Seoul according to the cooking attitude. Methods: During April 2018, an online survey was conducted on young adults of single-person households in their 20s and 30s residing in Seoul. The respondents were classified into the more positive cooking attitude group (More Positive Group; n=152, mean=4.11) and the less positive cooking attitude group (Less Positive Group; n=190, mean=3.03) based on the mean score (3.51) of the 4-item 5-point Likert scales measuring the cooking attitude. The responses of the two groups were compared. Results: Approximately 90% of the More Positive Group had the cooking ability to prepare ordinary meals or more advanced cooking skills, whereas only 61% of the Less Positive Group had such skills. Approximately a half of the More Positive Group cooked at home three times a week or more; only 30% of the Less Positive Group did so, and more than 30% of the group seldom cooked. The More Positive Group had higher mean scores in the levels of satisfaction with dietary life and care for food safety and nutrition than the Less Positive Group. Approximately 30% of all the respondents expressed their needs for community kitchens. The most frequently answered reason for such needs was "being able to have a meal with others". Conclusions: The young adults of single-person households with a more positive cooking attitude possessed a higher cooking ability, cooked more often, and cared more about food safety and nutrition than those with a less positive cooking attitude. There were moderate needs for community kitchens among young adults of single-person households living in Seoul. Therefore, societal efforts to improve their cooking attitude would be meaningful for improving their quality of dietary life. Cooking lessons or social dining programs based on community kitchens could be an option.

Population growth in Korea is slowing down, and the ratio of 1~2 person households has exceeded 53.3% of the total. And in the future, it is becoming more important how to accommodate as proper planning in residential areas. In this paper, we examine whether the existing district unit plans respond appropriately to the trend of the increase in small-sized housing, and we propose improvement plans for elements of the district unit plan and measures to enhance its applicability in response to small-sized housing. To do this, we analyzed the guidelines and contents of the district unit plans related to small-sized housing in recent 6 residential sites, and derived problems and improvements through literature review and expert consultation. As a result of the study, we proposed the items that need to be reflected in the district unit plan related to various housing type for one person household. And planning elements related to households, housing site, building layout, and architectural shape and appearance were also proposed, which were suitable for single-person households, such as small-sized communal housing, share-house, and single-person housing. It also suggested that single-person households should be considered for housing characteristics, including introduction of auxiliary welfare facilities such as unmanned delivery box and guest houses, and exclusion of low-demand auxiliary welfare facilities such as kindergartens. The suggested content can be used to make guidelines for small-sized housing in district unit plan.

Single-person household is estimated to be about 26.5% of the total household in 2015, which counts as 5060000 in numbers. We opt to acknowledge the various requests of these single residents, and in order to raise their satisfaction, we investigated on how personal taste, psychological interest, and personality attribute affects the user's preference of space organization and furniture in one room housing. Using the qualified psychology program, Enneagram Personality Type Indicator, we surveyed young people under 30 years old (majority of single-person households), regarding space organization and furniture preference. With the help of a specialist, the survey was constructed with appropriate evaluation items (space organization in one room households, bed, sofa, furniture material, etc), and analyzed the relationship between the evaluated items and personality types. Results showed there is a relationship between personality types and spatial structure. First, preference of spatial structure differed for different personality types. Second, the shape and size of furniture was dependent more on the ease of usability and design rather than on the personality types. One thing to consider is that type 1 and 9 accounted for about 50% of the total surveys. This emphasizes that the preferred spatial structure of a dominant specific personality type should not be overlooked.

This study investigates supply patterns and residential characteristics of the Urban-type Housing in Seoul. There have been 3,336 buildings and 71,790 housing units approved until the end of 2012. One-room apartments and small units less than 30 $m^2$ of residential area amount to 81% and 82% of total units, respectively. Major findings are as follows. First, single- and two-person households less than 30 years of age are mostly lived in the housing. Respondents are mainly professional and white-collar (43%) and service and sales workers (27%). Most of them are mid-income classes (67%), which is twice more than that of single- and two-person households in Seoul. They pay 672 thousand won in rent more than average rent of mid-income class. The rent to income ratios are 29.9% for single households and 24.5% for two-person households, which are higher than that of mid-income bracket. Third, their satisfaction level is relatively high in internal environment and access to public service facilities, but not in external environment and community service facilities. They are satisfied with security and daylight, walking and safety, access to public transport and parking space, but not with noise and vibration, natural environment, access to park and cultural and sports facilities, and most community service facilities. It is necessary to reexamine the articles of deregulation and prepare design standards while considering different housing and locational types.

According to a paper on estimating and forecasting the size of the pet-related industry published in 2018, 26.9% of the nation's pet-owned households were in their 30s and one-person households, consisting only of couples, as of 2015. Regarding the social increase in single-person households and double-income couples, it is believed that the surge in neglect time and lack of training time that pets do not want is a problem. This paper conducted the development of hardware and software products for the training and management of companion animals using Lego Mind Storm. Lego mind Storm is equipped with a variety of sensors and can produce equipment to train or care pets with simple programming through easy assembly and visual scripting. It is also expected that switching to new equipment will be easy because it is well modularized. We hope that this study will help the training and management of pets when the expansion of the pet market becomes active through this study.

The purpose of this study is to conduct research from qualitative aspects regarding the development of substantive design research for furniture brand and detailed development direction as single household has increased rapidly. In case of research method, the usability evaluation questionnaire was produced based on Honey Comb Model of Peter Morville. As a result, the single-person household including other household show preference for furniture for the one-man households and tend to purchase and use them. Nonetheless, it was found that places for sharing opinion and reselling the furniture are greatly lacking. Therefore, it is required to vitalize community market for the one-man household. And it is expected that this result of research provides useful implication concerning the single household as well as academic significance to offer primary information of furniture brand development-related research.
