BACKGROUND/OBJECTIVES: The increased consumers' interests in health and food safety have increased the demand for organic foods. Many studies have been performed on consumers' purchase intentions for organic foods and their influencing factors, and various studies have shown that the prices of organic foods and the consumers' willingness to pay are important influencing factors. This study examined the payment value of organic foods and agrifood consumer competency index according to the food-related lifestyles in South Korean consumers. SUBJECTS/METHODS: A cross-sectional analysis was performed using the 2019 Consumer Behavior Survey for Food. A total of 6,176 participants aged 19 to 74 years (male: 2,783, female: 3,393) were included in the analysis. RESULTS: Three factors were extracted by factor analysis (rational consumption-seeking type, convenience-seeking type, and health, and safety-seeking type) to explain the consumers' food-related lifestyles. The results of cluster analysis suggested that consumers were classified into 3 food-related lifestyles as the 'exploratory consumers' (n = 2,485), 'safety-seeking consumers' (n = 1,544), and 'passive consumers' (n = 2,147). Exploratory consumers showed a significantly higher willingness to pay for imported organic foods (P < 0.05). Safety-seeking consumers had a significantly higher willingness to pay for domestic organic foods (P < 0.05). For the agrifood consumer competency index, exploratory consumers had the highest score, followed in order by safety-seeking consumers and passive consumers. CONCLUSIONS: These results provide basic data in understanding consumption tendency for organic foods and agrifoods based on food-related lifestyles of South Korean consumers.

Purpose: This study aims to identify the factors that influence the experience of falls among older adults living in the community. Methods: The study participants were 70,887 65-year-olds who participated in the 2021 Community Health Survey. The study employed the Rao-scott x 2 test to examine the variation in fall experiences based on the characteristics of the older adults. Multiple logistic regression analysis was conducted to investigate these characteristics' impact on older adults' fall experiences. Results: The proportion of subjects in fall experience was 16.6%. The factors influencing the subject's fall experience were sex (odds ratio [OR]=1.47, 95% confidence interval [CI]=1.37~1.57), age (OR=1.48, 95% CI=1.34~1.65), family structure (OR=1.23, 95% CI=1.15~1.31), body mass index (OR=1.13, 95% CI=1.06~1.20), diabetes (OR=1.12, 95% CI=1.06~1.20), depression experiences (OR=1.56, 95% CI=1.42~1.70), stress (OR=1.12, 95% CI=1.05~1.19), subjective health status (OR=1.77, 95% CI=1.63~1.92), life satisfaction (OR=1.57, 95% CI=1.41~1.76), and chewing discomfort (OR=1.29, 95% CI=1.21~1.38). Conclusion: Efforts should be made to effectively educate and develop various programs aimed at reducing falls among older adults. It is essential to emphasize the importance of continuous and active attention to falls in the older adult population.

Background: Acute rhinosinusitis (ARS) is a common condition encountered in ambulatory practice and is one of the most common reasons for antibiotic prescriptions. This study aimed to evaluate the potentially inappropriate antibiotic prescribing for ARS in South Korea and identify influencing factors. Methods: We analyzed Health Insurance Review and Assessment Service-National Patient Samples data. We selected outpatients aged 20 to 64 with ARS, prescribed antibiotics between February and November 2020. Potentially inappropriate antibiotic prescribing was categorized as: 1) inappropriate antibiotic selection and 2) inappropriate antibiotic dosage or duration. Multiple logistic regression was conducted to estimate the impact of various factors on inappropriate antibiotic prescribing. Results: Of 1,210 patients, 80.83% received potentially inappropriate ARS antibiotic prescriptions. Inappropriate antibiotic selection accounted for 43.55%, and inappropriate antibiotic dosage and duration contributed to 37.28%. Otolaryngologists had higher odds ratio (OR) of potentially inappropriate antibiotic prescribing compared to internal medicine practitioners, while dentists had lower OR. Patients aged 20 to 29 years had a higher OR than other age groups, and those who visited primary care clinics had a higher OR than those who visited hospitals. Conclusion: Potentially inappropriate antibiotic prescribing for ARS is prevalent in South Korea. This study identified physician specialty, patient age group, and the level of healthcare facility as factors influencing potentially inappropriate antibiotic prescriptions. Addressing this issue through targeted interventions, such as improved guidelines adherence and patient education, is imperative to mitigate the risks associated with antibiotic misuse and antibiotic resistance.

Software piracy is widespread throughout the world. It has negative effects on the software industry and the intellectual property market. Despite various deterrent policies, the phenomenon has been getting severe. The current study investigated the antecedents of software piracy attitudes and intention. In order to identify factors and their relationship, a research model for illegal piracy behavior was developed and empirically examined through a path analysis using structural equation model. Also, this study employed a multiple group structural equation model to investigate differences in structural weights across PC software user group and smartphone application user group. It was revealed that perceived benefit, habit, social factor, self-efficacy had positive effect on attitude toward software piracy, whereas perceived risk had a decreasing influence on attitude. Relationships between piracy attitudes and intentions were significant as well. Furthermore, the cross validation between two groups showed the path coefficients of habit to attitude and attitude to intention were significantly different. Implications for research and practice are discussed.

The explosive growth of social commerce engenders a new business model, that is, infomediary. In a social commerce environment, infomediary works as a personal agent who provides information about various web merchants to help consumers select appropriate merchants for their needs. The purpose of this study is to identify the factors influencing consumer attitudes towards infomediaries in social commerce and examine the relationship between intention to provide word of mouth and consumer attitudes. In total, 170 responses were collected from social commerce infomediary users. The results show that competence and integrity significantly influence user attitudes as trust dimensions. Infomediary reputation and two functional factors (information variety and navigation functionality) turn out to be significant antecedents for user attitudes toward infomediary in social commerce. User attitudes in turn significantly influence the intention to provide word of mouth. Future research and practical implications are also discussed.

The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.

Self-consolidating concrete (SCC) is a recently developed innovative construction material. SCC fills in a formwork without any vibrating consolidation, which allows us to eventually achieve robust casting. However, high formwork lateral pressure exerted by SCC is a critical issue regarding its application as cast-in-place concrete. In order to control the risk caused by high formwork pressure, a comprehensive prediction model for the pressure was previously proposed, investigated, and validated with various SCC mixtures. The model was originally designed to simulate the intrinsic pressure response of SCC mixtures while excluding other extrinsic influencing factors such as friction and flexibility of the formwork. The model was then extended to consider extrinsic factors such as friction between SCC mixtures and formwork. In addition, other interesting topics for peak formwork pressure and mineral admixture effects were summarized in the paper.
