Depressive symptoms are one of the mental health problems among Korean American (KA) youth. Although several studies examined mental distress among KA youth, few have examined the associations between different familial factors, negative emotionality, and depressive symptoms among them, especially using longitudinal data. Drawing on the Triadic Model of Family Process (TMFP), this study examined the longitudinal associations between Korean-specific aspects of familial factors and depressive symptoms among KA youth and the mediation role of negative emotionality in the relationships.

Article Synopsis
  • - Asian Americans, the fastest-growing racial group in the U.S., face ongoing mental health disparities, especially during their teenage years, necessitating targeted research and interventions for this demographic.
  • - This study is the first longitudinal analysis focusing on how support from family, religious organizations, and schools influences mental health over time and varies by developmental stage and ethnicity among Filipino and Korean American adolescents.
  • - Key findings include that family support is a consistent protective factor against mental distress, while religious support is beneficial for Filipino American early adolescents, and school support aids all early adolescents, highlighting the need for culturally and developmentally aware mental health approaches.

Among the lead halide perovskite (LHP) family, CsPbI is known to be significantly vulnerable to moisture, which hinders its use in real device applications. It is reported that chalcogen-based ligands can better stabilize CsPbI and revive nanocrystals (NCs). Here, diphenyl diselenide (DPhDSe) ligand is used to revive the degraded CsPbI NCs through a post-synthetic treatment of adding a small amount of DPhDSe in the degraded NC dispersion.

Friendship racial homophily, the tendency to form friendships with individuals who share the same racial background, is a normative developmental phenomenon that holds particular significance for youth of color in a racialized society. Yet, there exists a paucity of longitudinal research elucidating the stability and change of friendship racial composition across developmental span. This study aimed to examine the friendship racial homophily trajectories over a six-year period encompassing four time points.

Although parental academic socialization may be a product of culture, ethnic/racial minority status may play a significant role, above and beyond the impact of culture, in shaping parental academic socialization and its implications for youth adjustments. This study examined Korean youth living in South Korea (N = 524, M = 14.98, SD = 1.

Drawing on Bronfenbrenner's (1977), this study examined the antecedents and outcomes of internalized model minority myth (MMM) within the microsystem of family and the macrosystem of culture. Among Korean immigrant families, we examined how mothers' internalized MMM (i.e.

Asian Americans are less likely than Whites to seek mental care and when they do, there is a substantial delay in help-seeking. Stigma associated with mental health service use is one of the major barriers to help-seeking among Asian Americans. However, few studies have examined multi-layered contextual predictors of stigma to examine joint as well as unique contributions of each predictor.

Wafer-scale growth of single crystal thin films of metals, semiconductors, and insulators is crucial for manufacturing high-performance electronic and optical devices, but still challenging from both scientific and industrial perspectives. Recently, unconventional advanced synthetic approaches have been attempted and have made remarkable progress in diversifying the species of producible single crystal thin films. This review introduces several new synthetic approaches to produce large-area single crystal thin films of various materials according to the concepts and principles.

Parental mental health socialization is a process by which parents shape how youth develop and maintain beliefs, attitudes, and behaviors regarding mental health and help-seeking behaviors. Although culture shapes parental mental health socialization, few studies have examined specific parental socialization practices regarding mental health and help-seeking, especially as a culturally anchored process. Using a qualitative approach, this study explores youth-reported parental socialization of mental health within Chinese American families by examining focus group data from 69 Chinese American high school and college students.

Although it is one of the core cultural values of Asian American families and an influential determinant of youth development, familism remains under-studied among Asian Americans and, despite crucial within-group heterogeneity, lacks subgroup specificity. This study describes the ways in which two major Asian American subgroups of youth, i.e.

The United States and China are top two receiving countries of Korean immigrants in modern history. Minority families in ethnically-racially diverse societies, such as the US and China, use various ethnic-racial socialization practices (cultural socialization, promotion of mistrust, preparation for bias) to help their children navigate the world, yet research in non-U.S.

This study investigates trajectories of racial discrimination, racial and ethnic socialization (RES), and their interaction effects with social positions (nativity and gender) on mental health. A longitudinal study of 786 Filipino American (FA) and Korean American (KA) youth from the Midwestern United States (M  = 15) confirmed that discrimination increased and significantly contributed to the upward trend of mental health distress, whereas the impact of RES differed by its type and by ethnicity. For example, promotion of mistrust and ethnic-heritage socialization were protective among U.

By using the conceptual framework of bilinear acculturation, this study examined Korean immigrant mothers' parenting practices among 389 mother-youth (adolescent children in middle or high school) dyads. We examined (a) how mothers' acculturation and enculturation were related to mainstream (i.e.

We explore the feasibility of implementing stereoscopy-based 3D images with an eye-tracking-based light-field display and actual head-up display optics for automotive applications. We translate the driver's eye position into the virtual eyebox plane via a "light-weight" equation to replace the actual optics with an effective lens model, and we implement a light-field rendering algorithm using the model-processed eye-tracking data. Furthermore, our experimental results with a prototype closely match our ray-tracing simulations in terms of designed viewing conditions and low-crosstalk margin width.

Guided by the concept of ABCDG (Abusive, Burdening, Culturally Disjointed, Disengaged, and Gender Prescriptive) parenting, this study investigated how subdomains of disempowering parenting adversely influence young people's mental health, independently and collectively, using a large-scale longitudinal survey data of community samples among Filipino American (FA) and Korean American (KA) youth ( =15.01, =1,580; 391 FA and 417 KA families). Regression results showed that the subdomains of disempowering parenting, while individually harmful, were differentially associated with mental health.

Berberine chloride (BBR) and evodiamine (EVO) are two main active ingredients of "ZuoJinWan", a classical Chinese herbal medicine, and these compounds are known to have a synergistic inhibitory effect on various cancer cell lines. Several recent studies have reported anti-melanoma effects for both BBR and EVO. However, topical delivery of the two compounds has been challenging, due to their poor aqueous solubility and their low skin penetration.

This study examined how parental cultural orientations and family process are related among Korean immigrant parents (272 mothers, and 164 fathers, =436) and how the relationship varies across fathers and mothers. Multiple scales were used to assess bilinear, multidimensional cultural orientation towards both the culture of origin and mainstream culture. The dimensions of language, identity, and cultural participation as well as the number of years living in U.

In this paper we present an autostereoscopic 3D display using a directional subpixel rendering algorithm in which clear left-right images are expressed in real time based on a viewer's 3D eye positions. In order to maintain the 3D image quality over a wide viewing range, we designed an optical layer that generates a uniformly distributed light field. The proposed 3D rendering method is simple, and each pixel processing can be performed independently in parallel computing environments.
