The purpose of this study was to analyze factors affecting US beef consumption intention in the future, to identify the causes of US beef import growth and to derive implications and strategies for domestic beef producers. Since the KORUS FTA was signed in 2012, US beef imports in 2017 totaled 379,064 tons, an annual increase of 3.5 percent. US beef imports have been steadily increasing due to cuts in FTA tariffs and changes in consumer preferences. The data used in this study utilized a sample of 3,290 grocery purchasers from the Korea Rural Economic Institute's 2016 Food Consumption Behavior Survey. The analytical method used the Ordered Logit Model to analyze what factors influence a consumer's subjective evaluation. As a result, the major factors affecting US beef consumption intention in the future are price, taste and safety. In particular, it has to do with the recent surge in U.S. imports of good-tasting chilled meat. Because chilled meat does not differentiate the market from Hanwoo beef produced in Korea, it is necessary to have differentiated taste and low price through cost reduction. By age and family group, people aged 30 - 40 years and single-person households are the main consumption group. As a result of this study, it is necessary to establish marketing strategies for producers such as rational pricing, safety, taste promotion, and small-scale sales to extend the demand for Hanwoo beef in the younger generation to enhance the competitiveness of the domestic beef market.

Objective: This study aims to conduct a comprehensive review of monitoring systems to monitor and manage physical function of community-dwelling elderly living alone and suggest future directions of unobtrusive monitoring. Design: Literature review Methods: The importance of health-related monitoring has been emphasized due to the aging population and novel corona virus (COVID-19) outbreak.As the population gets old and because of changes in culture, the number of single-person households among the elderly is expected to continue to increase. Elders are staying home longer and their physical function may decline rapidly,which can be a disturbing factorto successful aging.Therefore, systematic elderly management must be considered. Results: Frequently used technologies to monitor elders at home included red, green, blue (RGB) camera, accelerometer, passive infrared (PIR) sensor, wearable devices, and depth camera. Of them all, considering privacy concerns and easy-to-use features for elders, depth camera possibly can be a technology to be adapted at homes to unobtrusively monitor physical function of elderly living alone.The depth camera has been used to evaluate physical functions during rehabilitation and proven its efficiency. Conclusions: Therefore, physical monitoring system that is unobtrusive should be studied and developed in the future to monitor physical function of community-dwelling elderly living alone for the aging population.

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.

Recently, the number of pet owners has been increasing, and considering that the number of single-person households will increase further due to the low birth rate and aging population, the growth of the pet owner population is expected to continue. Accordingly, the pet-based industry is also expanding its base. In addition, as the time spent at home has increased due to COVID-19, the demand for products that help with pet owner care has increased, further maximizing the growth. Along with the growth of the pet-related industry, the size of the pet clothing and supplies market is also increasing explosively. Meanwhile, in relation to pet styling, services that simulate the expected appearance of a pet wearing a specific product are being developed, but services that assist pet owners in styling that is suitable for the physical and psychological characteristics of their pets are insufficient. Therefore, the purpose of this study is to provide a pet styling service provision device and method that can solve the problem of owners having difficulty judging whether styling is suitable for the physical and psychological characteristics of their pets by using pet fashion simulation.

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.
