This research aims to verify the generation transfer of proper manners from mothers to adolescent children and the relationship between adolescents' proper manners and strengths of family life. The data from 826 questionnaires (413 pairs of adolescents and mothers) were used for the final analysis. The findings of the study are summarized as follows: First, as for the extent of the implementation of manners of mothers and adolescent children both parties generally abided by good manners, but a significant difference emerged in the patterns. Second, both mothers and adolescent children were influenced by psychological determinants of self-esteem, values of humanism, emotional intimacy between mother and child, and social support for the implementation of good manners. On the other hand, adolescent children were affected the most by the emotional intimacy with mothers. Third, children generally showed significant differences in their implementation of manners according to the manners their mothers. Fourth, there were significant differences in the strengths of family life for adolescent children depending on their implementation of manners. Fifth, when comparing the relative contribution of the mothers' psychological determinants on strengths of family life and adolescent children's psychological determinants on the implementation of manners, strengths of family life gained more credibility as more variables were added.

It is known that there is an infinite family of general pretzel knots, each of which has Rasmussen s-invariant equal to the negative value of its signature invariant. For an instance, homologically ${\sigma}$-thin knots have this property. In contrast, we find an infinite family of 4-strand pretzel knots whose Rasmussen invariants are not equal to the negative values of signature invariants.

In this paper, a family of decentralized adaptive controller is proposed to control robot manipulators which are governed by highly nonlinear dynamic equations. The controller is computationally efficient since it does not require mathematical model or parameter values of the manipulators. The stability of the manipulators with the controller is proved by Lyapunov theory. The results of numerical simulations show that the system is stable, and has excellent trajectory tracking performance.

In this article, we prove some normality criteria for a family of meromorphic functions having zeros with some multiplicity. Our main result involves sharing of a holomorphic function by certain differential polynomials. Our results generalize some of the results of Fang and Zalcman [4] and Chen et al. [2] to a great extent.

In this paper we present a new family of identities for parametric Euler sums which generalize a result of David Borwein et al. [2]. We then apply it to obtain a family of identities relating quadratic and cubic sums to linear sums and zeta values. Furthermore, we also evaluate several other series involving harmonic numbers and alternating harmonic numbers, and give explicit formulas.

This study searched for the common and different aspects of social community welfare centers and health family support centers for family welfare practice of the community. We also tried to find out the awareness of workers and the performance function for each institution. Through the interviews and review of literature, and comparative analysis of operating status, we looked for the common and different aspects, and the direction of development, which evolved family welfare into the community by way of function and relationships of both institutions. As a result, the participants of this study pursued common purposes. They however made aware of the issues of discrimination about social values and each institution's functions. We suggest that the social community welfare center focuses on individuals and families, in order to integrate the community. A health family support center should play the role to fulfill needs for family welfare according to family life cycle, and have good accessibility for individuals and families in the community.

This study aimed to determine a tourist family's perceptions of dining at a holiday destination. A key assumption of this study was that dining at an unfamiliar locale at a tourist resort is engaging in risk-taking behavior by the tourist family. In this unfamiliar setting, participation in the local food market takes on a significant role in the tourist family's sense of satisfaction and loyalty. For the purpose of this study, involvement pertains to the family's perceived relevance of the objective of this study based on inherent needs, values, and interests. For this study, 151 subjects vacationing with his/her family on Jeju Island participated. To perform research on perceived risk and involvement in terms of the decision maker's capacity, only one member of each family responded to the survey, which examined the impact on sense of satisfaction of perceived risk and involvement in the local food scene. Perceived risks were divided according to financial, performance, physical, social-psychological, and time-risk factors. Perceived risk and involvement were found to be significant predictors of the overall satisfaction of the tourist family's local food consumption. Furthermore, performance risk was determined to be significantly linked to the tourist family's dining sense of satisfaction and loyalty. These findings provide some meaningful marketing implications for Jeju Island's tourism industry. Reducing the performance risk and increasing the local food involvement may activate rural tourism and local food consumption. Theoretical and practical contributions to local food marketing are discussed.

The purpose of this study was to explore what social media posts tell us about family life during the COVID-19 pandemic by examining the keywords and topics underlying posts on blogs and online forums. Our criteria for web crawling were (a) blog and forum posts on Naver and Daum, the top portal sites in Korea, (b) posts between February 23 and April 19, 2020, the period of the first heightened social distancing orders, and (c) inclusion of "COVID" and "family" or "COVID" and "home." We analyzed 351,734 posts using TF-IDF values and topic modeling based on latent Dirichlet allocation. We identified and named 22 topics including COVID-19 prevention, family infection, family health, dietary life and changes, religious life, stuck at home, postponed school year, family events, travel and vacations, concerns about family and friends, anxiety and stress, disaster and damage, COVID-19 warning text messages, family support policies, Shin-cheon-ji and Daegu. The results show that COVID-19 impacted various domains of family life including health, food, housing, religion, child care, education, rituals, and leisure as well as relationships and emotions.

Residential space has come to maintain a degree of specialization dependent upon the division of space according to function, while roles and functions have either expanded or ceased to exist corresponding to shifts in social values. However, various human behaviors connected to lifestyle habits and values are in fact becoming obsolete. This research will examine the mental, social, and functional aspects of the relationship between residential work spaces in modern homes and the sarangche as well as the communal space of daily and social life of the Chosun Dynasty to enhance the value and function of traditional residential space. As the boundary between family and work blurs with the home office environment of today, we are experiencing a deterioration of health and seeing problems in securing family domain as well as the prolonging of overwork. While the function of the traditional sarangchae encompassed a wider variety of activities than today's homes, the sarangchae achieved an efficient use of space divisions between rooms according to the particular purpose and situation. Accordingly, a reinterpretation of modern residential work space is needed through its connection to the sarangchae with consideration to the philosophy and values of the life of the noble class and the habits of our traditional lifestyle that have previously taken place within the sarangchae in an exterior space.
