The objective of this study is to provide new direction on house design in consideration of the user's life pattern. To this end, pc usage status at home, demand for pc using space, and requirements for pc room interior were analyzed. A survey was taken by parents and the SPSS win.10 was applied for analysis. The survey was conducted for 2 months, starting May 2004 to see the computer usage at home, demand and satisfaction for the computer's room. The results of this study were as follows; The oldest son or daughter in a family was the main user of the computer, posting 71%. 42percent of respondents said they used the pc in their son's and daughter's room while 36% answered living room. It reflects that the whole family want to use the pc in their sharing room, or for their children's convenience. Currently, inconvenience of space-related constraints for using the pc was not that high, which possibly stems from a lack of awareness of inconvenience in using the pc. However, the need for furniture and space for refreshment was suggested. Through this study, it is expected that new housing designs need to be made to reflect these requirements into interior design and building plan for user's convenience.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.

Services that enhance user convenience by using various IoT devices are increasing with the development of Internet of Things(IoT) technology. Also, since the price of IoT sensors has become cheaper, companies providing services by collecting and utilizing data from various sensors are increasing. The smart IoT home system is a representative use case that improves the user convenience by using IoT devices. To improve user convenience of Smart IoT home system, this paper proposes a method for the control of related devices based on data analysis. Internal environment measurement data collected from IoT sensors, device control data collected from device control actuators, and user judgment data are learned to predict the current home state and control devices. Especially, differently from previous approaches, it uses deep neural network to analyze the data to determine the inner state of the home and provide information for maintaining the optimal inner environment. In the experiment, we compared the results of the long-term measured data with the inferred data and analyzed the discrimination performance of the proposed method.

Due to the recent development of 3D printers, interest in 3D printing is growing. 3D printing should reflect individual needs and various requirements by designing products to suit the user's requirements. Research on how to use 3D printed products for the purpose of purchasing products according to user's demand characteristics is insufficient. Therefore, this study conducted a survey and statistical analysis to find out the factors influencing the intention of purchasing custom controller products in 3D printing environments. Research has confirmed that user innovation and convenience safety are important factors for the satisfaction and purchase intent of personal-tailored controller products. Considering user innovation, convenience, and safety when producing controller products using 3D printing, it is expected that value of custom controller manufacturing can be increased. Research is needed on the personalized product development framework that successfully introduces and systematically supports the production methods of personalized products in the early stages.

The purpose of this study is to investigate the relationship between product attributes of smart device and user acceptance of technology. Moreover, the authors examined mediating effect of utilitarian and hedonic motivation between product attributes and user acceptance. Previous researches focused on user attitude and behavior intention of new technology based on Technology Acceptance Model(TAM). However, differently from previous researches, which are focused on user attitude like perceived usefulness and perceived ease of use, this research emphasized the relationship product attributes such as product functionality, design, and convenience and user motivation both utilitarian(effort expectancy and performance expectancy) and hedonic motivation(perceived enjoyment) according to UTAUT model. The results shows that 3 motivation variables(effort expectancy, performance expectancy, and perceived enjoyment) have positive impacts on user acceptance intention of smart device. product design has positive relationship to perceived enjoyment and product convenience has positive relationship to both effort and performance expectancy. Furthermore, 3 motivation variables play a full mediation between product attributes and user acceptance intention of new technology. However, product functionality has no relationship to both effort and performance expectancy.
