Purpose: The purpose of this study is to examine the mediating effect of children's perceived peer attachment on children's subjective well-being and the effects of self-esteem, one of the variables of individual personality characteristics, on peer attachment and subjective well-being. Design: Data from the 2018 Panel Study on Korean Children were used. Methods: The survey method was conducted by the investigator, and the total number of cases was 1,434 people. Results: First, the higher the child's peer attachment leads to higher subjective well-being and self-esteem, and the higher the self-esteem leads to higher subjective well-being. Second, in the relationship between peer attachment and subjective well-being, self-esteem acts as a mediator variable. Third, children's peer attachment affects subjective well-being and self-esteem, and self-esteem affects subjective well-being. The results explain that the degree of children's peer attachment itself affects subjective well-being and self-esteem, and self-esteem also affects children's subjective well-being. Conclusion: Self-esteem is an important factor influencing subjective well-being and has a mediating effect on the relationship between peer attachment and subjective well-being. In other words, it can be understood that children feel subjective well-being through positive interactions with peers, not only in parent relationships. Based on these results, it is necessary to suggest practical interventions to enhance children's subjective sense of well-being and to develop various programs that can strengthen the sub-factors of peer attachment.

옥수수 알곡(whole corn)을 분쇄(ground corn; GC), 파쇄(cracked corn; CC), 박편(flaked corn; FC) 및 수침(soaked corn; SC)등 가공방법을 달리하여 처리하였을 때 반추가축에 있어서 미생물의 부착양상에 미치는 영향을 구명하고자 한 본 연구의 요약은 다음과 같다. 1. 한우의 반추위내에 각 처리별 옥수수를 12 및 24시간 배양하여 주사 전자현미경을 이용하여 반추 미생물의 부착양상과 사료 기질의 형태를 조사하였다. 2. 분쇄 및 파쇄 옥수수에서 가장 많은 미생물들이 부착되어 있는 것이 관찰되었고 옥수수 알곡 및 수침 옥수수는 전분입자에 미생물의 부착을 관찰 할 수 없었으며, 단지 배양시간이 경과함에 따라 옥수수의 외피에 많은 미생물이 부착되었고 외피의 분해가 일어나는 것이 관찰되었다. 3. SEM 결과를 통하여, 옥수수의 입자가 작게 가공처리 될수록 미생물 군락의 형성이 용이하여, 반추위내 옥수수의 분해율을 향상시킨다고 판단된다.

This study examined the impact of the social features (identification, interaction, information value) and technical features (visibility affordance, metavoicing affordance, social connecting affordance) in live commerce on consumers' attachment, which in turn affects consumers' continued intent to watch live commerce and intent to purchase from the platform. Consumers' attachment was represented by emotional attachment to the live shopping streamer and functional dependence on live commerce. Furthermore, this study investigated the effect of attachment on continuous watching intention and purchase intention. Using a web-based survey and consumers in their 20s and 30s (average age: 30.32) as a sample, this study collected 274 usable responses. The results showed that among the live commerce social system constructs, identification and interaction positively affected emotional attachment to the live commerce streamer. Among the live commerce technical system constructs, visibility affordance and social connecting affordance positively influenced functional dependence on live commerce. Both emotional attachment to the live streamer and functional dependence on live commerce were positively related to a continued intent to watch, which influenced the intent to purchase. This study empirically investigated live commerce based on the socio-technical systems framework and confirmed that both social and technical factors have a significant effect on consumers. This study also identified the impact of live commerce on consumers' attitudes through attachment theory. In addition, it has proved the antecedents and effect of continuous watching of live commerce on purchase behavior by focusing on continuous watching intention where less attention was paid in live commerce research.

The major purpose of the present research was to examine the effect of adolescents's perception of parents' marital relationship and attachment with their parents on school adjustment. This study also tried to investigate the inter-relationship among related variables, and the differences in the level of school adjustment according to adolescents' general characteristics. The participants were 355 middle and high school students who lived in Chollabuk-Do province. The major results of this research were as follows. First, there were significant differences in the level of school adjustment according to sex, age, and grade point. average That is, the level of school adjustment was higher for males, for older adolescents, and for those recording higher grade point, than for females, for younger, and for those recording relatively lower grade point. Second, parents' marital relationship was positively correlated with positive aspects of attachment with their parents(i.e., communication and trust), and with school adjustment. but negatively correlated with negative aspect of attachment(i.e., alienation from their parents). Finally, multiple regression analyses were performed to analyze the relative significance of the related variables influencing on school adjustment after controlling the effect of sex, age, and grade point. It was found that communication with fathers was the most powerful predictor of school adjustment, while attachment with mothers was not found to be a significant predictor of school adjustment.

Biological attachment device is optimized in insect legs for attachment onto the variety of natural substrate. We have studied the microstructural characteristics of the tarsal appendages in the ladybug Harmonia axyridis using scanning electron microscopy to reveal the attachment system of their legs. The attachment devices are composed of claws and adhesive pads. The claws are connected with pretarsal segment, and their apical diverged hooks are developed to hold rough substrates. In contrast, the adhesive pads have an adhesive function onto smooth surface. The pads are interspersed at the ventral part of each tarsomere, and are composed of two kinds of hairy setae. The discoid tip seta (DtS) has a spoon-shaped endplate usually with a rounded concave structure, whereas the pointed tip seta (PtS) has a pointed tip, usually with a hooked endplate. While the PtS is broadly localized concentrically on the marginal area of both the proximal and distal pads, the DtS can be seen at the central areas of each adhesive pad except for the hind legs. Our findings demonstrate the presence of the direction-dependence pattern of the fibrillar system as well as a functional modification of the tenent setae to achieve proper contact with almost any kind of substrates.

Clusters of parental and peer variables associated with adolescent risk behaviors are explored using the mixture model. Questionnaires were completed by 917 high school freshmen in the Daegu Kyungpook area and included measures of risk behaviors, parental attachment, autonomy, parental monitoring, and peers' risk behaviors and desirable behaviors. As a result of the mixture model, five clusters were produced. Two of the subgroups were consistent with the literature of showing linear relationships among adolescent risk behaviors and above variables; a group of higher parental attachment and autonomy as well as parental monitoring, lower friends' risk behaviors, and lower adolescent risk behaviors, and a group of lower parental attachment and autonomy as well as parental monitoring, higher friends' risk behaviors, and higher adolescent risk behaviors. Two other subgroups were similar in parental attachment and autonomy, but differed in parental monitoring, friends' risk behaviors, and adolescent risk behaviors. The last subgroup was characterized by scoring the lowest parental attachment and autonomy, parental monitoring, friends' risk behaviors, and lower adolescent risk behaviors compared to other subgroups. The utility of the mixture model in research on adolescent risk behaviors is discussed in the conclusion.

Recently, office workers are increasingly aware of the right to disconnect because of the pressure from strong connections with Internet messengers. In this study, we examined the reason why the perception of the right to disconnect increases and how to deal with it. This research model is that smart working and psychological attachment from work affect right to disconnect, and that open communication and gender moderate the intensity of these effects. To verify this research model, survey questionnaires were distributed to workers in smart working environments, and 400 data were collected and analyzed using Smart-PLS. As results of data analysis, it was verified that smart working and psychological attachment from work had a significant influence on right to disconnect, that open communication group had a lesser effect of psychological attachment from work on right to disconnect than closed communication group, and that women had a lesser effect of psychological attachment from work on right to disconnect than men. Organizations need to maintain a desirable level of right to disconnect in order to improve the quality of working life. But, if it is impossible, They need to change the way of communication more openly so as to absorb the burden of strong connection by Internet. And they need to perform task assignment or stress relief policy reflecting gender characteristics.
