Highly transparent TiO 2 nanoparticles are explored as a non‐electrochromic (non‐EC) charge‐balancing layer for a high color contrast, bistable electrochromic window (ECW). The TiO 2 nanoparticle (TNP) layer increases the potential at the EC polymer electrode, thereby lowering the working voltage of the ECW. This leads to lower the power consumption of ECWs without loss in the high color contrast (Δ T > 72%) and to remarkably improve the cyclability (Δ T change <1% over 3000 cycles), mainl

Misunderstandings about autism may be more common in South Korea than the United States. Koreans often have clear ideas about how people should act. Another way of saying this is that Korea has a tight culture. Americans are looser, meaning people are freer to act as they like. Autistic people often do not act as people expect them to. This makes autistic people stand out. Autistic people may stand out more in tight cultures like South Korea. We studied how people in South Korea and the United S

An efficient thin film acoustic energy harvester was explored using flexible poly(3,4-ethylene dioxythiophene) (PEDOT) films as electrodes in an all-organic triboelectric generator (AO-TEG). A thin film AO-TEG structured as PEDOT/Kapton//PET/PEDOT was prepared by the solution casting polymerization(SCP) on the dielectric polymer films. As-prepared AO-TEG showed high flexibility and durability due to the strong adhesion between the electrodes and the dielectric polymer. The short-circuit current

Despite a general consensus on the negative consequences of emotion suppression in Western cultures, cross-cultural explorations to date have yielded many inconsistencies on whether such phenomena can be generalized to Eastern cultures. A set of two studies were conducted to examine the role of emotional valence in resolving such inconsistencies on both relationship satisfaction and subjective well-being. In accordance with our hypotheses, our results consistently revealed that the habitual supp

How people report their feelings about autism may be different from how they actually think about autism because some people may not want to reveal their true feelings. People who value the group's goal tend to present themselves as more socially acceptable than people who value one person's interests. We studied how people in South Korea and the United States report their feelings about autism and think about autism. Koreans tend to value the group's goals. Americans tend to prefer one person's

Research in the past 2 decades has made great strides in understanding cross-cultural differences in the correlates and causes of subjective well-being. On the basis of past findings on the cross-cultural differences in temporal perspectives of the self, the present research examined a cross-cultural difference in individuals' subjective well-being as a function of how positively they viewed their present and past selves. Study 1 showed that both European and Asian Americans had higher subjectiv

According to the theories on interpersonal mattering, reciprocal interactions and mutual engagements facilitate the formation of interpersonal mattering within relationships. However, the theoretical framework on mattering has rarely been applied to understand the roles of sexual and verbal exchanges within intimate relationships. To fill this research gap, the authors proposed that heightened perception of mattering captures the common mechanism through which both frequent sex and communication

An intriguing phenomenon that arises from decision making is that the decision maker's choice is often influenced by whether the option is presented in a positive or negative frame, even though the options are, <i>de facto</i>, identical to one another. Yet, the impact of such differential framing of equivalent information, referred to as the attribute framing effect, may not be the same for every culture; rather, some cultures may be more readily influenced by the differentially valenced frames

Emotional suppression has been considered a critical factor in determining one's mental health and psychological well-being in intimate relationships such as marriage. The present study aimed to delineate the nuanced association between emotional suppression and psychological well-being in marriage by considering two critical factors: (a) individual differences in motivational orientation and (b) the perceived level of a partner's emotional suppression. A set of two online survey studies were co

Set by government, corporate, financial, and individual sources, venture capitals(VCs) in South Korea adapted themselves to a new and uncertain VC market through stand-alone as well as syndicated investments. This study raises questions about whether the various financial sources differentially preferred and contributed to their portfolio firms even during the market boom in 2000. Even though there was no single capital source to show better performance, only corporate VCs are found not only to

People from all cultures are averse to looking dumb in front of others, especially if there is a large audience. However, there could be a difference between Face and Dignity cultures in the extent to which their members see themselves as dumb when they perform poorly before a large versus small audience. In the present study, Chinese and Americans were asked to imagine themselves performing poorly on tasks either in front of 10 others or one other and make judgments about how poorly (a) they th

Set by government, corporate, financial and individual sources, venture capitalists in Korea have adapted themselves to the new and uncertain venture capital market through stand-alone and syndicated investments. The present study raises questions about whether various financial sources contributed differentially to their portfolio firms during the market boom of 2000.

The image of an ideal woman often involves her having long, silky hair. However, the dearth of psychological research on hair limits the understanding of how women's hair functions in romantic relationships. While some scholars have found that the appearance of women's hair signals reproductive potential to men, whether women's hair may affect their sexual lives remains unknown. To investigate the function of hair in romantic relationships, we tested whether women's hair quality and length are a
