The purpose of this study was to examine group differences in paternal behaviors (i.e., paternal connection, paternal punitiveness, and paternal knowledge) within and across three academic achievement levels-low, moderate, and high, and to explore the effects of paternal behaviors on the academic motivation of Chinese adolescents within these three achievement groups. Analyses of variance (ANOVAs) indicated that adolescents with low achievement perceived their fathers as more punitive than teens with moderate and high academic achievement. Regression analyses also revealed that paternal punitiveness (negative) and paternal knowledge (positive) were significant predictors of academic motivation for teens with low levels of academic achievement; while paternal punitiveness was a significant negative predictor of academic motivation among adolescents with moderate achievement. In contrast, for adolescents with high achievement, paternal connection was a positive significant predictor of academic motivation. The present findings provide some evidence that the impact of parental behaviors on teen's motivation varies across adolescent academic achievement levels, which may prove useful for professionals working with fathers to help target the most effective parenting behaviors to foster academic motivation.

Immediately after fertilization, a chromatin remodeling process in the oocyte cytoplasm extracts protamine molecules from the sperm-derived DNA and loads histones onto it. We examined how the histone H3-lysine 9 methylation system is established on the remodeled sperm chromatin in mice. We found that the paternal pronucleus was not stained for dimethylated H3-K9 (H3-$m_2K9$) during pronucleus development, while the maternal genome stained intensively. Such H3-$m_2K9$ asymmetry between the parental pronuclei was independent of $HP1{\beta}$ localization and, much like DNA methylation, was preserved to the two-cell stage when the nucleus appeared to be compartmentalized for H3-$m_2K9$. A conspicuous increase in H3-$m_2K9$ level was observed at the four-cell stage, and then the level was maintained without a visible change up to the blastocyst stage. The behavior of H3-$m_2K9$ was very similar, but not identical, to that of 5-methylcytosine during preimplantation development, suggesting that there is some connection between methylation of histone and of DNA in early mouse development.

The aim of this study was to explore the types of helicopter parenting among college students, and to examine how the identified types of helicopter parenting are associated with intimacy goals in dating. In order to investigate these purposes, 202 college students were recruited and analyzed. With the use of Mplus 7.4, a latent profile analysis identified latent profiles of helicopter parenting. Additionally, multivariate regression analysis was conducted in order to analyze the links between the types of helicopter parenting and intimacy goals in dating by using SPSS 26.0. The main findings of the study were as follows. Firstly, three helicopter parenting classes were identified: 1) strong decision-making, 2) strong helicopter parenting, 3) weak helicopter parenting. Secondly, college students in the strong helicopter parenting class reported significantly higher levels of intimacy goals in dating than those in the strong decision-making class. On the other hand, no significant connection was identified between the type of 'weak helicopter parenting' and the levels of intimacy goals in dating, referencing the type of 'strong helicopter parenting.' These results indicate that helicopter parenting has a certain number of types in nature, and the control-based parental behavior could have an impact on college students' intimacy goals in dating.

그림책은 글과 일러스트레이션으로 구성되어 상호유기적인 관계를 형성하며 이야기를 전개해 나가는 예술형식이다. 그림책에서 글과 일러스트레이션이 전달하는 의미뿐 만 아니라 상호작용을 통해 새롭게 만들어 내는 상징적 의미를 이해한다면 그림책을 보는 즐거움과 가치를 깨닫게 될 것이다. 그림책의 글과 일러스트레이션을 불가분의 관계에 놓인 하나의 단위로 보고 기호학적으로 분석하는 것은 그림책 이해에 중요한 관점을 제공한다. 세계적인 그림책 작가 앤서니 브라운(Anthony Browne)의 '고릴라'를 기호학자 그레마스(A.J. Greimas)의 의미작용 이론을 통해서 글과 일러스트레이션의 상호보완작용을 이해한다. 또한, 텍스트와 조형표현의 구조적 관계를 심층적으로 분석하고 통합적으로 전달되는 이야기를 새로운 관점으로 접근한다. 기존의 연구들에서 앤서니 브라운의 '고릴라'는 주인공 한나와 아빠의 관계를 단순한 외로움으로 전체 이야기 의미를 해석하였지만, 본 연구를 통해 그 관계에 있어 부성애뿐 만 아니라 이성애가 존재하며 그 갈등의 해소가 주된 관점으로 새롭게 해석될 수 있다.
