Purpose: The no-contact and economic downturn caused by COVID-19 have further grown the used market. The second-hand trading industry has established itself as a popular consumption culture, leading to exponential growth in the size of the market. This study aims to identify the types of shopping motivation for used products targeting Korean consumers, and to examine the relationship between shopping motivations for second-hand transactions, consumption values, and re-use intentions. Research design, data and methodology: The first study was conducted on 63 used trading platform users and the second study was conducted on 441 used trading platform users to identify the types of consumers' motivation for shopping for used products. Results: As a result of the first study, the shopping motivation types of Korean used product consumers were classified into convenience motivation, economic motivation, hedonistic motivation, information Acquisition motivation, and free time utilization motivation. As a result of the second study, it was found that convenience motivation had the greatest influence on functional values and hedonic motivation had the greatest influence on emotional values, and that functional values had a great influence on platform reuse intentions. Conclusions: This study provides practical implications for the establishment of marketing strategies for used trading platforms and academic implications for research related to used trading.

Purpose. Despite the high prevalence of back pain and its subsequent effects in post-partum women, intervention programs are scarce. The purpose of this study was to test the effects of a back-pain-reducing program on post-partum women who experienced low-back pain during pregnancy. Methods. A non-equivalent control-group pretest-posttest design was used. Pregnant women who attended a hospital for prenatal check-ups and experienced back pain participated in an intervention program (n=27), and the results were compared with women in a control group from another hospital (n=25). Results. At 8 weeks post-partum, the pain intensity, functional limitations were lower in the intervention group than in the control group. However, differences in mean change of the pain intensity and functional limitations between 36 and 39 weeks of gestation and at 8 weeks post-partum were not statistically significant between the groups. Moreover, the flexibility, post-partum functional status, and post-partum depression did not differ significantly between the groups. Conclusions. A back-pain-relief program in this study was not effective to reduce the back-pain intensity in post-partum women and to decrease the associated functional limitations. The implications for nursing practice and directions for future research are discussed.

Purpose - This study is to investigate the effects of consumption values of retailers on the importance of store attributes, and to determine the influence on the consumption values of consumers who shop at complex shopping malls on the empirical and functional attributes in those malls as well as on the influence of on/off-line channels. Research design, data, and methodology - With 344 surveyed questionnaires, this study was conducted by using SPSS 22.0 to verify the reliability and validity of the measured variables. Structural equation model (SEM) was employed as a statistical method for the hypotheses test of this study. Results - The results showed that hedonic value has more influence on the importance of empirical attribute than that of functional attribute in shopping malls. In addition, practical value has more influence on functional attributes than empirical properties of shopping malls. However, these relationships showed the difference in on/off-line channels. As for off-line channels, consumers' consumption values were more influential on empirical attributes, while functional attributes were more important in on-line channels Conclusions - This study analyzed the influence on the importance of the consumption values in store attributes, and the effects of each channel with suggesting practical implications.

Purpose: The purposes of this study were to explore the functional status of elderly residents and to analyze time use, and finally identify factors to predict nursing care needs in relation to functional status and health related variables. Methods: In this study a descriptive-correlational design was used. Functional status of participants was obtained through interviews, and nursing care time was examined using a 1 min time-motion study with a standardized instrument developed by Korea Long-Term Care Planning Committee (2005). Results: The mean total functional score was 65 (range 28-125) and mean total nursing care time was 144.15 min per day. There were significant positive relationships between total nursing care time, marital status, back pain, dementia, and vision impairment. Multiple regression analyses showed that a liner combination of number of illnesses, types of primary disease, ADL, IADL, cognitive function, nursing demand, and rehabilitation demand explained 42.8% of variance of total nursing time. ADL (${\beta}$=-.533) was the most significant predictor of nursing service need. Conclusion: Identifying factors that result in variations of service need has implications for adequate nursing service, estimation of optimum nurse to patient ratio, quality of care and patient safety.

The purpose of this research was to investigate the factors influencing global expansion/scalability of Kenyan Small and Medium Enterprises (SMEs). Factor analysis and multiple/multivariate regression analysis to determine the functional relationship between independent variables (factors) and the dependent variable was used. The independent variables were: innovation & technology, fitness/appropriateness of management, global marketing strategy; and support environment and the dependent variable, global expansion/scalability. Data was collected from a survey of randomly selected firms of 205, drawn from a population of 440 firms from Kenya Manufacturers Directory, with 175 firms responding. The key findings from the research in relation to Kenyan SMEs were that: there is a functional relationship between global market strategy and global expansion; there is a functional relationship between innovation and technology orientation and global expansion, there is no significant functional relationship between supportive environment of firms and their global expansion; and there is no significant functional relationship between fitness/appropriateness of management and global expansion/scalability. The implications for practice is that the ranking of the factors in order of priority supports focusing concern on the orientation of business strategy toward global market strategy, market research geared at obtaining foreign market intelligence, innovation and technology, product adaptation, service orientation, collaborative ventures, and long-range vision as key factors in making Kenyan firms successful in the international market. The implication for policy and practice is that there is need for collaboration between industry and government in pursuing policies for global expansion/scalability and among SMEs and large enterprises particularly in areas of rapid technological change.

The implications of germline de novo variants (DNVs) in diseases are well documented. Despite extensive research, inconsistencies between studies remain a challenge, and the distribution and genetic characteristics of DNVs need to be precisely evaluated. To address this issue at the whole-genome scale, a large number of DNVs identified from the whole-genome sequencing of 1,902 healthy trios (i.e., parents and progeny) from the Simons Foundation for Autism Research Initiative study and 20 healthy Korean trios were analyzed. These apparently nonpathogenic DNVs were enriched in functional elements of the genome but relatively depleted in regions of common copy number variants, implying their potential function as triggers of evolution even in healthy groups. No strong mutational hotspots were identified. The pathogenicity of the DNVs was not strongly elevated, reflecting the health status of the cohort. The mutational signatures were consistent with previous studies. This study will serve as a reference for future DNV studies.
