Due to the increase in single-person households among the people who have companion animals, it is difficult to feed them to companion animals in the absence of the owner, so an automatic feeding machine was designed. In this paper, we propose an automatic feeding machine that has a drug distribution function as well as feeds using the Arduino platform. It is expected that in the proposed automatic feeding machine, users can access the food service through the website, and experience the convenient and extended food service function through the automatic dispensing system that combines the two materials.

Due to the recent surge in single-person households, solitary death is drawing attention as an important social problem. We herein develop an adaptive monitoring system using RFID to protect the socially disadvantaged who are exposed to the risk of solitary death. The developed system consists of a wearable RFID tag, an RFID reader attached to the residence, and a user monitoring App. The developed system measures the retention time of a user with a wearable tag in a place where a reader is attached. When the retention time exceeds an adaptively determined threshold, an emergency notification is sent to the caregiver. We verify the effectiveness of the designed system by implementing a prototype modeling a residence based on Arduino.

Purpose: This study aims to explore the factors affecting the willingness to pay for chicken delivery services targeting college students. The results of this study provide insights for improving food delivery market services and developing effective marketing strategies. Research design, data and methodology: A survey employing a questionnaire was administered to students at Chungbuk National University over a 10-day period from May 15 to May 24, 2023. Out of 232 distributed surveys, 218 were considered suitable for analysis. Binomial logistic regression analysis was conducted with the willingness to pay for delivery fees contingent on chicken price, serving as the dependent variable. Results: The main findings are following. First, as the price of chicken increases, the percentage of individuals willing to pay more than 2,000 won for delivery services decreases. Second, regardless of chicken price, males exhibit a lower tendency to bear higher delivery service fees compared to females. Lastly, those who lack awareness of their recent delivery fees or have previously paid charges exceeding 3,000 won demonstrate a greater propensity to pay higher delivery service fees compared to those who have paid fees below 3,000 won. Conclusions: It is essential for chicken sellers to identify key customer segments such as single-person households, and offer pricing and services tailored to their needs and preferences.

Accurate household projections are essential for sectors such as housing supply and tax policy planning, given the rapid social changes like declining birthrates, an aging population, and a rise in single-person households that impact household size and type. Korea introduced its first register-based census in 2015, transitioning from five-year general survey-based approach to an annual administrative data-based census. This change in census allows for more frequent and effective capturing the rapid demographic shifts and trends. However, this change in census has caused challenges in future projection by the existing household projection model due to the rapid dynamics. This paper proposes a new household projection method, the N-point Modified Exponential Model (MEM), that accurately reflects register-based census data and mitigates the impact of rapid demographic changes, in three types: the Weighted N-point MEM, the Regression-based N-point MEM, and the Rolling Weighted N+point MEM. Using register-based census data from 2016 to 2020 to forecast household headship rates by age, household size, and household type to 2051, the N-point modified exponential model outperformed the existing model in both long- and short-term forecast accuracy, suggesting its suitability as a future household projection model for Korea.

Purpose - The purpose of this study is to ascertain the influence of individual consumption values and consumption tendencies on repurchase intention. It aims to examine how individual characteristics affect purchasing behavior in response to social environmental changes. Design/Methodology/Approach - This study targeted individuals who have experience purchasing convenience store lunches in Korea and collected 201 survey responses. Exploratory Factor Analysis (EFA) and Multiple Regression Analysis were employed to analyze the data. Findings - Individual consumption values significantly influenced consumption tendencies. Additionally it was found that both consumption values and consumption tendencies have some significant impact on repurchase intention. However, certain factors had a significant influence specifically in the context of negative relationships, which was analyzed to be influenced by social environmental changes. Research Implications and Limitations - This study verified the clear relationship between consumption values, consumption tendencies, and repurchase intention, such as product purchase. However, it also verified that the relationship of these factors does not necessarily have a strictly positive impact. It suggests that future marketing research should also investigate factors such as the increase of single-person households and social environmental changes.

The purpose of this study was to analyze the financial portfolios of single-person households. For the analysis, The purpose of this study is to verify the mediation effect of stress-coping strategies in the relationship between ego-resiliency and burn-out among childcare center teachers. The subjects were 255 childcare center teachers in Gyeongbuk Province. The measurement tools used for this study include ego-resiliency, burn-out, and stresscoping strategy questionnaires. The collected data points were analyzed via Structural Equation Modeling(SEM), Bootstrapping, Pearson Correlation, using SPSS 21.0 and AMOS 20.0 The results of the study analyzing the Structural Equation Model are as follows. First, teachers' ego-resiliency had a negative influence on burn-out. Second, teachers' problem-focused coping strategies had a negative influence on burn-out, while emotionfocused coping strategies had a positive influence on burn-out. Third, teachers' ego-resiliency had a positive influence on both problem-focused and emotion-focused coping strategies. Fourth, teachers' ego-resiliency had an indirect effect on burn-out by improving both problem-focused and emotion-focused coping strategies. This study suggests that education on the use of problem-focused coping strategies in stressful situations is necessary to successfully manage childcare teachers' burn-out in childcare settings in which mandatory evaluation systems are newly implemented.

Surveys are an important data collection method for national statistics in Korea. As of July 22, 2024, based on data provided by the MDIS of Statistics Korea, approximately 92% of national statistics are compiled using the survey method, and about 85% of these rely primarily on face-to-face interviews for data collection. However, with the increase in single-person households, the nonresponse rate of surveys has been rising each year. This study examined the behaviors of respondents across different survey modes used in the 2020 Korean Crime Victim Survey, whose raw data about survey response modes is available for public use on the MDIS website in Statistics Korea. The results show that, overall, the younger the age group, the higher the proportion of self-administered responses, with this proportion being higher for female than male except over 60 years old. Notably, the 20s age group has a significantly higher percentage of self-administered (TAPI) responses for both male and female. Furthermore, the response using tablets generally has a higher proportion compared to the response using paper across all age groups except for females in their teens, regardless of whether the survey is interviewer-administered or self-administered.

This study is a study on the development of virtual reality to prepare for the increase in disasters of households living with companion animals due to the increase of companion animals. The increase in single-person households and DINKs(Double Income, No Kid) along with the low birth rate and aging population is raising the risk of disasters caused by companion animals in particular. Among these disasters, there is an increase in the occurrence of fires primarily due to the raising of companion animals. Electric stove fires caused by pets are the most common fires. In particular, the frequency of electric stove fires caused by cats is the highest. Careful precautions by the owner are necessary to reduce fires caused by pets. Parenting of companion animals causes pet loss syndrome due to emotional exchange. There are injuries to pets in escalators and injuries to owners in elevators due to disasters caused by the owner's negligence. In order to reduce injuries on escalators and elevators, basic etiquette for using escalators and elevators with pets is required as basic etiquette. It is necessary to utilize virtual reality to reduce disasters caused by such companion animals. Virtual reality can be experienced without a physical space in advance training to overcome disasters, so real disaster cases can be experienced immersively. Therefore, learning how to reduce fires caused by companion animals, disasters caused by owner's negligence, and petloss syndrome through virtual reality will greatly contribute to disaster prevention and reduction of social costs.

The home interior market has been expanding due to the continuing increase of single-person households, the craze for DIY interior design, the increasing demands for old-house renovation and the customer needs for good housing conditions. Now the building materials companies are scrambling for the whole interior market share. The heretofore companies have focused only on the single items, but now they are promoting the comprehensive interior products as total interior brands. Besides, they use their own showrooms to share their brand culture experience and have communication with their customers. As for the show rooms, they have got to represent the identities of the building materials brands. And to present them effectively, it needs to meet the customer needs and emotions. In this connection, the object of this study is to clarify the definitions and the characteristics of the show rooms and the experience design through the literature research, analysis the space characteristics of the experience design in the show rooms of total interior brands, investigate their customer satisfaction and present the direction and the effective methods of the space design for the show rooms of the future. And the study result shows the experience design is the key factor to the high user satisfaction. Thus, the show rooms should provide the well-balanced experience with the adoption of a variety of experience design elements. Especially, the experience design elements are needed in the room to display the merchandise. Lastly, the show rooms are expected to increase constantly, so the study targeted at the specific area, Seoul should be expanded to other areas. And this study based on the customer survey alone have a limit to giving the concrete proposals. Therefore, the follow-up studies with the different methods such as one-to-one interview will be in demand.

A safe residential environment enhances the quality of human life and promotes community development through self-actualization. It significantly affects regional stability by influencing the physical and psychological environment necessary to satisfy basic needs, providing a sense of security and alleviating anxiety. Safety is a major housing need; however, current housing policies tend to focus predominantly on housing supply. This emphasis limits the fulfillment of higher-level needs due to poor housing conditions and housing cost burdens faced by young households. Therefore, this study aims to identify areas affected by the stigma effect by analyzing the discrepancy between perceived crime risk and actual crime occurrence among single-person young households. The study compares these stigmatized areas with regions where the perceived crime risk is lower than the actual crime occurrence to identify differences in housing needs satisfaction and to prioritize policy interventions. Additionally, the study examines differences in housing needs satisfaction and importance based on gender to inform policy priorities. By considering the stigma effect on regional housing needs and gender-specific deficiencies, this study provides significant policy implications.
