The purpose of this study was to identify the ecological variables related with children's emotional intelligence, examine their recognition of all the variables affecting their emotional intelligence and classify the variables into the categories of children (gender, grade, self-efficacy), home environment (employed mother or unemployed mother, communication between parents and child, type of family composition, number of siblings), and peer group environment (peer group). The study subjects were 680 elementary school students. Data were analyzed via t-test, F-test, correlation, and multiple regression. The results of this study were as follows. First, emotional intelligence showed significant difference and relationship among the children variables, home environment variables, and peer group environment variable. (Ed- also note the absence of 'fourth' above) Second, emotional intelligence in children was relatively reviewed by the above three variables and the most affecting variable was self-efficacy in children.

In this study, the formation of nanoparticles by a reaction of ozone with the volatile organic compounds(VOCs) emitted from a commercial home cleaner liquid was investigated using a $1-m^3$ reaction chamber($1{\times}1{\times}1m$). The home cleaner liquid was found to contain many VOCs, particularly terpenes. Some of these VOCs are known to readily react with ozone, forming indoor secondary pollutants. The correlation of particle concentration and reacted ozone concentration was examined with injections of three different ozone concentrations; 50, 100 and 200 ppb. The secondary nanoparticles were formed faster, with their numbers and mass concentrations becoming higher on increasing the concentration of ozone injected.

Smart home in the 4th industrial revolution environment is where all devices in the home are connected to each other to provide the optimal living environment desired by the user. Artificial intelligence speakers are being used as a way to manage and control all devices used in this environment. The function of an artificial intelligence speaker ranges from simple music playback to serving as an interface that controls and manages all devices in a smart home space. In this study, we investigated and analyzed the usability of artificial intelligence speakers based on the current status of domestic and overseas markets and the survey contents of two organizations (Korea Consumer Agency and Korea Information and Communication Policy Institute (KISDI)). In addition, we investigated and analyzed the usability of artificial intelligence speakers. Based on the results of responses from users from two related organizations, major problems were derived, and major improvement measures, such as discovering new functions and improving voice recognition performance, were also described.

With a rapidly aging population, the proportion of elderly households with low income has been increasing. Despite the poor housing environment, it is not easy to improve their housing environment due to the high cost of modification. However, as many elderly want to keep living in their current houses, it is urgent to improve their housing environment. The purpose of this study was to develop the guidelines on home modification for low-income elderly. This study set the scope of home modification categories through literature analysis in advance to develop the guidelines. Based on the literature analysis and small group workshops, the primary and secondary guidelines were derived and a total of 169 final guidelines were produced based on the scope of home modification categories. Those guidelines were composed of the categories by space, divided into mandatory and recommended by details. Those guidelines proposed in this study were classified and composed under the objective standards, so that they were systemic and objective based on the verification of experts. They are considered to get closer to the user's demand on the basis of the demand of low income elderly for home modification and the improvement categories under the system to support home modification for low income elderly at home and abroad. In addition, as the standards to apply each guideline, separated into mandatory and recommended, was suggested, those guidelines may help expand the scope of improvement under the economic conditions for home modification.

The purpose of this study is to propose a model for evaluating comfort of indoor environment based on residents' subjective respones. The questionnaire survey was given to the residents at apartment complex located in Ilsan, Kyunggi-Do. The following are the results obtained in this thesis. The results of path analysis on comfort revealed that direct effects to comfort were the satisfaction on thermal environment, indoor air environment and sound environment, and the cognition on indoor air environment and sound environment. An evaluation formula of comfort by the factors of direct effects was given. This formula is recommended to evaluate comfort for pp.O.E(post occupancy evaluation)by residents.
