Purpose: Based on the health belief model and theory of planned behavior, this study investigated how age group (adolescence and emerging adulthood) moderated the relative effects of perceived susceptibility, perceived severity, and subjective norms on preventive behavior against coronavirus disease 2019 (COVID-19). Methods: This secondary data analysis utilized data from adolescents (n=272) and emerging adults (n=239). Hierarchical multiple regression analysis was performed to test the moderating effect of age group on the relationships among variables. Results: Higher perceived susceptibility (β=.21, p<.001), perceived severity (β=.14, p=.002), subjective norms (friends) (β=.26, p<.001), subjective norms (parents) (β=.44, p<.001), and subjective norms (schools) (β=.28, p<.001) enhanced COVID-19 preventive behaviors. Moderated regression analysis showed that subjective norms (friends and school) impacted preventive behavior in adolescents more than in emerging adults. Conclusion: Given the need to increase perceived susceptibility and severity among adolescents and emerging adults, these findings provide baseline data for designing effective COVID-19 prevention interventions that consider the developmental characteristics of different age groups. Interventions by health centers at universities can strengthen COVID-19 preventive behavior among emerging adults. As adolescents are influenced by friends, their peer roles must be strengthened to enhance adherence to COVID-19 preventive guidelines.

The literature on parent-child relationships in young adulthood lacks a systemic approach that considers the multifaceted nature of intergenerational relationships. In this paper, we identify the latent profiles of young Korean adults' relationships with their parents based on the six dimensions of intergenerational solidarity (structural, associational, affectual, consensual, functional, and normative solidarity) as indicators. We considered solidarity for the mother and the father separately for structural, associational, affectual, and consensual dimensions. In terms of functional and normative solidarity, we measured both upstream and downstream intergenerational support. The sample included 1,015 young adults who were 19-34 years old, never married, not in secondary school, and had both parents living. The latent profile analysis revealed four profiles: (a) independent but intimate (22.7%), (b) coresident, outwardly intimate (32.4%), (c) detached from father (6.7%), and (d) coresident, intimate (38.2%). The factors that predicted each profile included the young adults' education, income, subjective socioeconomic status, and experiencing the features of emerging adulthood along with the parents' marital status, father's employment, and overparenting. The "coresident, intimate" group reported significantly higher levels of life satisfaction and fewer depressive symptoms compared to the other three groups. The lowest levels of psychological adjustment were found in the "coresident, outwardly intimate" group and "detached from father" group.

Objective: The purpose of this study was to examine the reliability and validity of the Korean version of the Helicopter Parenting Scale (HPS) using a sample of Korean young adults aged 19-34. This study is to expand the previous validation studies that exclusively focused on college students. Method: The survey data came from 1,140 young adults (398 19-24 year olds, 376 25-29 year olds, and 366 30-34 year olds) who had never been married and had at least one living parent. The young adults' perceived helicopter parenting was assessed by 10 items of the HPS for the mother and the father separately. All of the analyses including exploratory and confirmatory factor analyses were conducted for three age groups (19-24, 25-29, and 30-34 years) and for the mother and the father separately. Results: We found that three items were problematic for all age groups and for both the fathers' and mothers' helicopter parenting. After removing these three items, confirmatory factor analyses showed that the one-factor model fit our data well and the estimated factor loadings were suitable. The results were consistent throughout the age groups and the parent's gender. We also confirmed criterion-related validity using correlations between paternal and maternal helicopter parenting and three dimensions of parental career expectations indicated a reliable. Conclusion: The Korean version of HPS with seven items was found to be a reliable and valid measure for Korean young adults aged 19-34 years old.

Objective: In this study, we examined the psychometric properties of the Korean Intergenerational Psychological Ambivalence Scale (KIPAS) for young adult children. Method: Data came from 1,140 Korean young adults aged 19-34, who were never married and had at least one living parent. We translated the individual-subjective dimension of Zygowicz's (2006) Intergenerational Ambivalence Scale from English to Korean. The individual-subjective dimension had eight items that directly measured intergenerational psychological ambivalence (D-KIPAS) and 10 items that indirectly measured intergenerational psychological ambivalence (I-KIPAS). Results: The D-KIPAS and I-KIPAS items showed good internal consistency both for the mother and the father. Confirmatory factor analysis showed that D-KIPAS items loaded on one factor after controlling for method effects, which allowed error variances among the four non-reversed items to covary. Both the positive and negative items of I-KIPAS had good reliability and loaded on the same factor. The mean score of D-KIPAS and the calculated score of I-KIPAS were significantly but moderately correlated, which indicates that the D-KIPAS and I-KIPAS assess correlated but distinct aspects of intergenerational ambivalence. Correlations among D-KIPAS, I-KIPAS, and the proxy variables of intergenerational solidarity and conflict supported the discriminant validity of the KIPAS. Conclusion: The results of this study suggest that both D-KIPAS and I-KIPAS are reliable and valid tools to measure intergenerational psychological ambivalence among Korean young adults.

Objectives: Away-from-home (AFH) eating has been associated with poor diet quality and health outcomes like obesity in developed countries. AFH eating is also emerging in low-income countries, but its influence on overall diet quality is under-researched. We examined the prevalence of AFH eating and its influence on the dietary patterns of Ugandan adults. Methods: This cross-sectional study employed a web-based survey to interview Ugandan adults aged 18 ~ 65 years. A qualitative food frequency questionnaire was used to assess the food group intake, which was then converted into daily intake frequencies. Principal component analysis was used to derive dietary patterns. The participants were then classified based on the tertiles (T) of dietary pattern scores. Results: About 75% of the 375 participants reported eating AFH. The young men, food insecure, and urban dwellers were more likely to eat AFH ≥ 5 times/week. Three dietary patterns emerged; the animal-based, beverage pattern; the high fat, sweet pattern; and the traditional, plant-based pattern. Participants who frequently ate AFH were 2.85 times and 5.64 times more likely to be in the second and third tertiles, respectively, of the animal-based, beverage pattern compared to the rare eaters (OR = 2.85, 95% CI: 1.35-6.06 for T2 vs T1; and OR = 5.64, 95% CI: 2.50-12.73 for T3 vs T1). The odds of being in the second tertile of the high fat, sweet pattern was significantly higher for frequent AFH eaters compared to the rare eaters (OR = 2.61, 95% CI:1.23-5.52). Conclusions: The prevalence of AFH eating was high. Frequent AFH eating was common among the young, male, food insecure, and urban dwellers, and was associated with unhealthy dietary patterns.

The purpose of this study was to examine which sibling and parent-child characteristics were associated with siblisng warmth and conflict among Korean young adults. The data came from an online survey of Koreans aged 19-34 years who had at least one sibling and two living parents. We conducted a multilevel regression analysis using data from 193 men with 305 siblings and 203 women with 286 siblings. The results showed that, for men, the levels of warmth were higher when the sibling was younger, when they received more frequent financial and instrumental support from the sibling, and when maternal favoritism was relatively lower. Women reported higher levels of warmth when the sibling was a sister, when they provided more frequent support for the sibling, when they had a more affectionate relationship with the mother, and when paternal favoritism was lower. As for sibling conflict, the number of siblings was positively associated with the levels of conflict among both men and women. Maternal affection was negatively related with conflict for men, and paternal favoritism was positively related to conflict for women. Interestingly, women's sibling warmth and conflict were both higher when the sibling was a sister, which meant that relationships between sisters tended to be ambivalent. This study contributes to our understandings of Koreans' sibling relationships in young adulthood.

The purpose of this research is to investigate young consumer motivation in regards to shopping mall. Young adults are an emerging age group that has economic autonomy and power of making independent decisions. In addition, this young segment providing an interesting challenges and opportunities for marketing professionals. Therefore, it is pertinent to analyse their shopping motivations, so that the marketers can understand and influence the consumption behaviour of this specific group. A survey using self-administered questionnaire was conducted to assess the mall-directed shopping habits and shopping orientations. A total of 164 usable surveys were obtained. In addition of exploratory factor analysis, confirmatory factor analysis and structural equation modeling was applied to prove the hypotheses. We have found that young Australian shoppers were motivated to visit malls primarily by the role enactment and exploration dimensions. They were the strongest motivators which explaining why young Australian consumers patronize malls. Young consumers of Australia enjoyed the mall environment, exploring new things, socializing with friends, comparing prices and the variety of products and services offered. The results of our study have several implications that should be of benefit to the retailing industry and mall management. Developers of malls must develop their mall more than simply a place for buying products. As such, mall management should make sure that their mall atmospherics offer a mall environment that is pleasing to multiple senses, to ensure it is conducive for shoppers to stay and spend more of their time and money. Mall management must execute strategies to maintain their attraction to younger consumers, perhaps by including stores that are futuristic and offer the most advanced styles or technologies, and appeal to somewhat older adults by offering the tenant, entertainment, and experience mix they will prefer. It is recommended that future research utilize random sampling methods to ensure the generalizability of results.

The present study examined how the psychological well-being of young adults was affected by the perceived parental rearing attitudes and how self-concept clarity and the perceptions of emerging adulthood mediated this causal relationship based on Arnett's the theory of emerging adulthood. We specially focused on affectionate or rejective types of perceived parental rearing attitudes and possibility or instability perceptions of emerging adulthood. We performed survey research with 358 university students from six universities located in Seoul, and other cities in South Korea and analyzed collected data using SPSS 25.0 and SPSS Macro. As a result, we found correlational relationships between psychological well-being of emerging adulthood and other variables. Also, we found the mediating effect of the self-concept clarity in the relationship between the psychological well-being and the perceived parental attitudes: affectionate, rejective. However, we only found the mediating effect of the perceived possibility perception of emerging adulthood was significant in the relationship between the psychological well-being and affectionate parental rearing attitudes. Finally, we found a sequential mediation effect that the self-concept clarity and then perceived instability perception of emerging adulthood affected in the relationship between psychological well-being and rejective parental rearing attitudes of emerging adulthood. Based on results, implications and suggestions for counseling service and psychological education for university students faced emerging adulthood were discussed.

This study examined the biological characteristics of the insect and examined potential cultural controls using peduncle topping methods. Ginseng stem fungus gnat eggs hatched after 5 days; ecdysis lasted 3-4 weeks, and after 5 days pupation, adults emerged. Adults deposited eggs 1-2 days after emerging, and the entire life cycle lasted 32-40 days. The fungus gnats laid eggs $327\times220{\mu}m$ in size on cut planes of stems, but not on intact stem parts that had not been topped or wounded. Analyses of major weather data for the experimental areas and weather data for the past 30 years acquired from the Korea Meteorological Administration revealed that fungus gnat dispersion was prevalent under highly humid conditions and in areas with thick and frequent fogging. Among the topping times examined, fungus gnat damage to ginseng was lowest when topping occurred in late May. Among the five different topping methods evaluated on experimental ginseng farms, the cumulative fungus gnat damage to ginseng was low (0.8%) under partial peduncle topping (removal of peduncle with lateral fruit remaining) and removal of only flower buds (0.6%), with fungus gnat control effects of 82% and 86%, respectively, compared to conventional topping (removal of peduncle about 5 cm above its base). No fungus gnat damage to ginseng was observed under the no-topping treatment. These results suggest that partial topping of peduncles, while letting lateral fruits remain, is a potentially environmentally friendly method of controlling the ginseng stem fungus gnat.

As an effort to further extend the existing understanding on the Psychology of Working Theory, this study examined gender differences in the paths to the attainment of decent work with Korean emerging adults. A total of 311 South Korean employees (mean age = 25.96, men = 94, women = 217) completed online questionnaires. We found that economic constraints inversely predicted work volition and career adaptability, which were positively relatedin turn, led to decent work. The overall indirect effect of work volition and career adaptability between economic constraints and decent work was significant., hHowever, the specific indirect effect of work volition and career adaptability was not significant. Further analyses showed a gender difference in the paths. Specifically, economic constraint was significantly negatively associated with work volition, and work volition predicted decent work only for women, but not for men. Moreover, economic constraint was significantly inversely associated with career adaptability, and career adaptability positively predicted decent work only for men, but not for women. Work volition mediated between economic constraints and decent work for women, while career adaptability had a mediating effect for men. It suggests that career resources for obtaining a decent work may be distinctive by genderdifferent groups.
