Legal analysis of South Korean cosmetic filler litigations for safer medical practices.

Cosmetic filler injections have gained popularity in recent years, but the rise in complications has led to an increase in legal disputes. This study analyzes civil court rulings related to cosmetic filler injection lawsuits in South Korea from 2007 to 2023. A retrospective case analysis was performed using a systematic database search, and a mixed-methods approach was employed for data analysis. The study examined 27 cases, revealing a high rate of liability findings against medical practitioners. Skin necrosis and blindness were the most common complications, and intravascular filler injection was recognized as negligence. Violation of informed consent was found in most cases, with mean compensation awards of ￦193,019,107 KRW ($142,831 USD) for first instance cases and ￦81,845,052 KRW ($60,564 USD) for second instance cases. The findings emphasize the importance of practitioner awareness, adherence to precautionary measures, and proactive prevention and management of complications. Collaboration among stakeholders is crucial for developing strategies that prioritize patient safety and minimize legal disputes in the aesthetic medicine industry. This study provides valuable insights for enhancing medical practices and safeguarding patient well-being in the field of cosmetic filler injections.

The Interplay between Tunneling and Parity Violation in Chiral Molecules.

In this review, the concepts of quantum tunneling and parity violation are introduced in the context of chiral molecules. A particle moving in a double well potential provides a good model to study the behavior of chiral molecules, where the left well and right well represent the L and R enantiomers, respectively. If the model considers the quantum behavior of matter, the concept of quantum tunneling emerges, giving place to stereomutation dynamics between left- and right-handed chiral molecules. Parity-violating interactions, like the electroweak one, can be also considered, making possible the existence of an energy difference between the L and R enantiomers, the so-called parity-violating energy difference (PVED). Here we provide a brief account of some theoretical methods usually employed to calculate this PVED, also commenting on relevant experiments devoted to experimentally detect the aforementioned PVED in chiral molecules. Finally, we comment on some ways of solving the so-called Hund's paradox, with emphasis on mean-field theory and decoherence.

Analytic Formulae for T Violation in Neutrino Oscillations.

Recently, a concept known as µTRISTAN, which involves the acceleration of µ+, has been proposed. This initiative has led to considerations of a new design for a neutrino factory. Additionally, leveraging the polarization of µ+, measurements of T violation in neutrino oscillations are also being explored. In this paper, we present analytical expressions for T violation in neutrino oscillations within the framework of standard three-flavor neutrino oscillations, a scenario involving nonstandard interactions, and a case of unitarity violation. We point out that examining the energy spectrum of T violation may be useful for probing new physics effects.

Updating predictions in a complex repertoire of actions and its neural representation.

Even though actions we observe in everyday life seem to unfold in a continuous manner, they are automatically divided into meaningful chunks, that are single actions or segments, which provide information for the formation and updating of internal predictive models. Specifically, boundaries between actions constitute a hub for predictive processing since the prediction of the current action comes to an end and calls for updating of predictions for the next action. In the current study, we investigated neural processes which characterize such boundaries using a repertoire of complex action sequences with a predefined probabilistic structure. Action sequences consisted of actions that started with the hand touching an object (T) and ended with the hand releasing the object (U). These action boundaries were determined using an automatic computer vision algorithm. Participants trained all action sequences by imitating demo videos. Subsequently, they returned for an fMRI session during which the original action sequences were presented in addition to slightly modified versions thereof. Participants completed a post-fMRI memory test to assess the retention of original action sequences. The exchange of individual actions, and thus a violation of action prediction, resulted in increased activation of the action observation network and the anterior insula. At U events, marking the end of an action, increased brain activation in supplementary motor area, striatum, and lingual gyrus was indicative of the retrieval of the previously encoded action repertoire. As expected, brain activation at U events also reflected the predefined probabilistic branching structure of the action repertoire. At T events, marking the beginning of the next action, midline and hippocampal regions were recruited, reflecting the selected prediction of the unfolding action segment. In conclusion, our findings contribute to a better understanding of the various cerebral processes characterizing prediction during the observation of complex action repertoires.

Different but also alike? Ingroup-outgroup phenomena among cyclists and e-scooter riders.

PROBLEM: In many countries, a new road user group, e-scooter riders, share the existing cycling infrastructure. The study aimed to investigate if an individual's status as a cyclist or e-scooter rider affects their social identity and whether it results in ingroup favoritism or outgroup discrimination. METHOD: An online experiment involving 179 cyclists and 64 e-scooter riders was conducted, where they rated the behavior of ingroup or outgroup members in six traffic scenarios. RESULTS: Participants rated dispositional attributions as more causally relevant than situational ones across all traffic scenarios. Cyclists and e-scooter riders were inclined to judge ingroup members' rule violations more harshly than those of outgroup members in terms of dispositional attribution ratings and punishment severity. For situational attributions, few indications of ingroup favoritism were observed for the e-scooter rider group. SUMMARY: Findings suggest initial indications of considerate coexistence, from the perspective of social identity theory, between the two modes of transport, supporting current regulations on the use of cycling infrastructure by e-scooter riders. Indications of ingroup discrimination, however, suggest that safety campaigning may target to promote courtesy within the cyclist and e-scooter rider groups.

To err is human but to persist is diabolical: Toward a theory of interactional policing.

Social interaction is organized around norms and preferences that guide our construction of actions and our interpretation of those of others, creating a reflexive moral order. Sociological theory suggests two possibilities for the type of moral order that underlies the policing of interactional norm and preference violations: a morality that focuses on the nature of violations themselves and a morality that focuses on the positioning of actors as they maintain their conduct's comprehensibility, even when they depart from norms and preferences. We find that actors are more likely to reproach interactional violations for which an account is not provided by the transgressor, and that actors weakly reproach or let pass first offenses while more strongly policing violators who persist in bad behavior. Based on these findings, we outline a theory of interactional policing that rests not on the nature of the violation but rather on actors' moral positioning.

Identification, Evaluation, and Correction of Supracrestal Tissue Attachment (Previously Biologic Width) Violation: A Case Presentation With Literature Review.

The supracrestal tissue attachment (SCTA) is the new terminology for biologic width. SCTA is defined as the physiologic dimension of a solitary functional unit composed of junctional epithelium and connective tissue attachment. Its preservation is critical for the well-being of periodontal health. SCTA has been widely studied and scientific literature is indicative of its significance during the placement of restoration, including prosthetic crowns. This should be taken care of in cases of anterior teeth within the smile zone, where dental crowns are regularly placed subgingivally for aesthetic reasons. In addition, any violation of SCTA while restoring the dentition will present as gingival inflammation and pain, consequently, leading to failure of the clinical procedure.

Impact of bilateral facet joint violation on radiographic degeneration of superior adjacent segments and clinical outcomes.

OBJECTIVE: Facet joint violation (FJV) is associated with postoperative low-back pain and is a confirmed risk factor for adjacent-segment degeneration, a long-term complication of lumbar fusion surgery. The authors' knowledge of its mechanisms comes from in vitro biomechanical research only; there is a lack of radiographic evidence of the effects of violation on the superior adjacent-segment facet joint, intervertebral disc, and other local radiographic parameters. Furthermore, any differences between unilateral and bilateral violation remain relatively unclear. The authors therefore aimed to explore the effects of nonviolation and unilateral and bilateral violation on radiographic degeneration of the facet joint and intervertebral disc at the fusion and superior adjacent segment. Patient-reported clinical outcomes were compared at the 2-year follow-up. METHODS: The authors retrospectively analyzed data from 148 patients with lumbar degenerative diseases who underwent single-segment minimally invasive transforaminal lumbar interbody fusion between 2016 and 2020. FJV and facet joint degeneration were evaluated and graded using Shah's method and Pathria's standard, respectively. Radiographic parameters, including disc height and intervertebral Cobb angle at the fusion and superior adjacent segment, were measured. Clinical outcomes were evaluated using visual analog scale (VAS) and Japanese Orthopaedic Association scores. RESULTS: Preoperative data were comparable among the 3 groups (nonviolation, unilateral violation, and bilateral violation) (p > 0.05). Patient-reported clinical outcomes were followed up for at least 2 years (average duration 28.17 ± 6.17 months). At the last follow-up, facet joint degeneration grades were sequentially increased in the nonviolation, unilateral violation, and bilateral violation groups (p = 0.006). The unilateral (2.45 ± 2.17 mm) and bilateral (2.70 ± 1.94 mm) violation groups had more severe losses of disc height in the superior adjacent segment than did the nonviolation group (1.31 ± 2.01 mm). The VAS low-back pain and Japanese Orthopaedic Association scores in the bilateral (2.57 ± 1.44 and 19.83 ± 2.84, respectively) and unilateral (2.26 ± 0.79 and 20.43 ± 3.85, respectively) violation groups were significantly worse than in the nonviolation group (1.69 ± 1.12 and 21.80 ± 3.36, respectively) (p < 0.05). By contrast, there were no significant between-group differences in disc height, intervertebral Cobb angle in the fusion segment, or VAS leg pain scores (p > 0.05). CONCLUSIONS: FJV was associated with postoperative low-back pain and worse functional outcomes. It also aggravated facet joint and intervertebral disc changes in the superior adjacent segment, especially when bilateral violation occurred; this may be part of the mechanisms of adjacent-segment degeneration.

Comedy, consensus, and conflict framework: Comedy as a norm violation can build consensus or escalate conflict in negotiations.

In this work, we propose that humor violates norms that can build consensus or escalate conflict in negotiations. Drawing on social identity theory, we propose that humor commits norm violations that are more likely to be perceived as benign among ingroup observers in negotiations, but perceived as offensive to outgroup observers in negotiations. We introduce the Comedy, Consensus, and Conflict Framework to shed light on the interpersonal effect of humor on negotiations. When humor is expressed to an ingroup observer, relative to neutral communication, humor is more likely to violate weak norms that govern social group membership resulting in the violation as being perceived as benign, which promotes cooperative behaviors in negotiations such as concessions and collaborative problem-solving. By contrast, when humor is expressed to an outgroup observer, relative to neutral communication, humor is more likely to violate strong norms that define social group membership resulting in the violation as being interpreted as offensive, which triggers competitive behaviors in negotiations such as aggressive offers and hardened positions. Furthermore, we suggest that humor not only generates appraisals of social identity threats, but also affective responses that influence negotiation behavior. Finally, we expand our theoretical model about humor to consider key relational factors that influence norm strength, which motivates whether negotiators appraise norm violations as offensive or benign.

Cognitive and Relational Processes Associated to Mental Health in Italian High School Students during COVID-19 and Russian-Ukrainian War Outbreaks.

The negative impact of the COVID-19 pandemic on mental health has been widely demonstrated; however, few studies have investigated the psychological processes involved in this impact, including core beliefs violation, meaning-making disruption, interpersonal support, or one's relational functioning. This study explored the mental health of 215 Italian adolescents during the COVID-19 pandemic and the subsequent outbreak of the Russian-Ukrainian war. By administering a set of questionnaires, several cognitive and emotional variables were investigated, including core belief violation, meaning attribution to the pandemic and war, attachment, and emotion regulation, social media addiction, and relationships with significant others and teachers. We conducted some descriptive, mean difference, correlational, and predictive analyses that revealed a significant association between core belief violation caused by war and pandemic, ability to integrate war and pandemic within personal meaning universe, the relational support received, and mental health. The relationship with teachers during these challenging periods improved significantly according to the respondents' opinion, becoming both more authoritative and empathic. This study offers insights into what cognitive and relational processes are useful to intervene on to reduce the distress of adolescents who are facing significant moments of crisis due to events that challenge their cognitive and emotional balance.

Restraint validation of biomolecular structures determined by NMR in the Protein Data Bank.

Biomolecular structure analysis from experimental NMR studies generally relies on restraints derived from a combination of experimental and knowledge-based data. A challenge for the structural biology community has been a lack of standards for representing these restraints, preventing the establishment of uniform methods of model-vs-data structure validation against restraints and limiting interoperability between restraint-based structure modeling programs. The NEF and NMR-STAR formats provide a standardized approach for representing commonly used NMR restraints. Using these restraint formats, a standardized validation system for assessing structural models of biopolymers against restraints has been developed and implemented in the wwPDB OneDep data deposition-validation-biocuration system. The resulting wwPDB restraint violation report provides a model vs. data assessment of biomolecule structures determined using distance and dihedral restraints, with extensions to other restraint types currently being implemented. These tools are useful for assessing NMR models, as well as for assessing biomolecular structure predictions based on distance restraints.

Examining the trajectory of meaning violation and its bidirectional relationship with perceived posttraumatic growth.

Despite extensive theoretical discussions on the dynamic process of meaning violation (MV) and restoration, empirical research on this topic remained lacking. This study aimed to explore the trajectory of MV and the bi-directionality between MV and perceived posttraumatic growth (PPTG). This study employed a 3-wave longitudinal design spanning over 3 months, and a sample of participants from China who experienced any distressing event within the past 3 months was considered eligible. Participants (N = 215; aged 18-38 years old) were instructed to assess MV and PPTG regarding a chosen event. A latent growth model was used to examine changes in MV over time and a random intercept cross-lagged panel model was used to analyze bidirectional associations between MV and PPTG. Results revealed that, at the within-person level, MV at T1 negatively predicted PPTG at T2, while PPTG at T2 negatively predicted MV at T3. These results indicate that the sense of MV may have impeded PPTG in the initial stages, whereas PPTG might serve as a predictor for diminished MV at later stages. At the between-person level, a positive relationship between these two constructs was observed, suggesting that individuals who experienced higher levels of MV, in general, also tended to report greater PPTG. These findings reflect the complex and dynamic nature of meaning reconstruction processes and provide empirical evidence for the meaning-making model.

ProjectDRIVE: study protocol for a randomized controlled trial to improve driving practices of high-risk teen drivers with a traffic violation.

BACKGROUND: Teen drivers with a traffic violation are at increased risk for crashes and crash-related injuries; however, most parent-focused interventions target teen drivers with supervised learner's permits. Very few interventions are implemented at the probationary driver's license stage or target high-risk teen drivers, such as those with traffic violations. This paper describes the protocol of ProjectDRIVE, A Randomized Controlled Trial to Improve Driving Practices of High-Risk Teen Drivers with a Traffic Violation, which targets improving parent-teen communication about safe driving practices to reduce unsafe driving behaviors and traffic violation recidivism of teen drivers cited for traffic violation. METHODS: Teen drivers (ages 16 or 17) cited for a moving violation and the parent/legal guardian most involved with the teen's driving are recruited from juvenile traffic courts following their required court hearing. After completing informed consent/assent, enrolled dyads are randomized into one of three groups using stratified block randomization: control, device feedback only, or device feedback plus parent communication training. Participating dyads are followed for 6 months with 3 months of active intervention. Using in-vehicle device and smartphone application technology, the study provides real-time and cumulative driving feedback to intervention teens and collects continually recorded, objectively measured driving outcome data throughout the teen's study participation. Primary outcomes include rates of risky driving events and unsafe driving behaviors per 1000 miles driven. Secondary outcomes include traffic violation recidivism up to 12 months following study completion and frequency and quality of parent-teen communication about safe driving practices. DISCUSSION: Through partnership with the local juvenile traffic courts, this study integrates recruitment and randomization into existing court practices. Successfully completing this study will significantly impact juvenile traffic court's practices and policies by informing judges' decisions regarding the driving safety programs they refer to teens to prevent motor vehicle crashes and crash-related injuries and deaths. Trial registration The study was registered on ClinicalTrials.gov Registry (NCT04317664) on March 19, 2020, https://clinicaltrials.gov/study/NCT04317664 and updated on April 27, 2021. This protocol was developed per the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) Checklist.

Risk Factors for Multiple Violations of Protective Orders in Intimate Partner Violence Against Women.

This study examined 1,134 cases of violence against women in intimate partner relationships with violations of protective orders in a monitoring period of up to 15 months. The dynamics of time and violence were analyzed in the cases of multiple violation versus one-time violation, with the objective of identifying and thus neutralizing the risk factors for this type of recidivism. The results showed that early violation, serious physical violence, death threats, as well as jealousy, harassment, and control are related to multiple violation. This article discusses the results in comparison with other research and proposes measures to avoid revictimizations.

Pornography Use and the Acceptance of Gender Norm Violation in a School Context.

Although media effect studies have quite extensively investigated the association between pornography use and gendered attitudes, some questions remain. The present study aimed to address two of these questions by exploring how gendered attitudes and gender beliefs may be influenced by gender typicality and pornography use. First, the literature has not yet accounted for individual differences based on gender typicality. Second, the influence of pornography use on gender beliefs going beyond pornography's script application is understudied. This online cross-sectional study (N = 1,440, Mage = 23.86, SD = 4.79) contributes to the field by investigating the indirect association between pornography use and acceptance of gender norm violation through gendered attitudes and the moderating role of gender typicality. Acceptance of gender norm violation was measured via vignettes describing a school context in which a teacher and a student violated gender norms. Findings indicated that gendered attitudes negatively relate to the acceptance of gender norm violation. Moreover, compared to women, men's pornography use indirectly relates to lower acceptance rates through gendered attitudes. Additionally, for men, specific levels of gender typicality and atypicality form a strengthening and buffering role, respectively. This applies to the association between pornography use and gendered attitudes as well as to the indirect relationship of pornography use with acceptance of gender norm violation. These findings suggest that pornography use may also affect gender beliefs that are unrelated to the scripts present in pornography. Future studies should take into account the type of preferred pornography and unravel the specific impact of women's pornography use.

Influence of perceived social support on detection of social norm violation: evidence from N1 and N400.

Introduction: The perceived social support individuals receive from their others plays a crucial role in shaping conformity with social norms. However, the specific mechanism underlying perceived social support and the detection of social norms remains unclear. Methods: In this study, college students with high and low levels of perceived social support were asked to judge the appropriateness of stranger's behaviors (e.g., singing) in different situations (e.g., library). The participants' electroencephalography activities were analyzed aiming to uncover the neural mechanism underlying how perceived social support influences the detection of others' normative behavior. Results: The ERP results indicate that, for individuals with a lower level of perceived social support, larger amplitudes of the N1 component (related to primary processing) and the N400 component (related to cognitive conflict) were observed when detecting others' social norm violation compared to the conformity condition. However, for individuals with a higher level of perceived social support, no significant differences were found in detecting others' conformity or violation of social norms. Discussion: The results indicate that, when the perceived social support level of the individual is low, detecting others' social norm violation elicits deeper primary processing and stronger cognitive conflict compared to conformity condition.

Effectiveness of exposure-based treatment for childhood anxiety disorders: An open clinical trial to test its relation with indices of emotional processing and inhibitory learning.

BACKGROUND AND OBJECTIVES: The current study examined how effectiveness of exposure-based CBT was related to indices of emotional processing and inhibitory learning during exposure exercises. METHODS: Adolescents with anxiety disorder(s) (N = 72; age 11-19; 85% girls) received a group-based, intensive two-week treatment of which effectiveness was indexed by the SCARED and by ratings of anxiety and approach towards individualized goal situations. To index emotional processing, subjective units of distress (SUDs) were used to indicate both initial and final fear level, and absolute, relative, and total dose of fear reduction. To index inhibitory learning, subjective threat expectancies (STEs) were used to indicate initial and final threat expectancy, and absolute, relative, and total dose of expectancy change. RESULTS: From pre-treatment to follow-up, there was a large-sized reduction of anxiety symptoms, small-sized decrease of subjective anxiety and a large-sized increase in subjective approach towards individual treatment goals. Higher fear levels prior to exposure were related to a larger decrease of symptoms. Higher threat expectancies after exposure exercises were independently associated with less decrease of anxiety and increase of approach towards treatment goals. Total dose of experienced fear reduction and total dose of experienced expectancy change were (partly) independently related to more increase in approach towards individualized goal situations. LIMITATIONS: As patients also received other treatment elements, the results cannot be interpreted unequivocally. CONCLUSIONS: The pattern of findings seems to indicate that emotional processing (as indexed by fear reduction) and inhibitory learning (as indexed by expectancy change) are both relevant in exposure-based CBT.

Humor and morality in organizations.

Successful leaders often use humor to motivate, inspire, and lead. Yet, recent research suggests that the use of humor is risky for leaders. Our review suggests that humor must be morally offensive to some people for it to be perceived as funny. This inherent tension between humor and morality implies that the use of humor can sometimes act as a signal of acceptable moral standards in organizations, where a leader's use of humor carries significant risks because of the norm-violating message it sends to subordinates, or it can even be dangerous in extreme cases. We conclude the paper by offering future research directions on the study of workplace humor.

Preexposure to one social threat alters responses to another social threat: Behavioral and electrophysiological evidence.

A recent Cyberball study has indicated that the experience of loss of control can affect how people process subsequent social exclusion. This "preexposure effect" supports the idea of a common cognitive system involved in the processing of different types of social threats. To test the validity of this assumption in the current study, we reversed the sequence of the preexposure setup. We measured the effects of social exclusion on the subsequent processing of loss of control utilizing event-related brain potentials (ERPs) and self-reports. In the control group (CG, n = 26), the transition to loss of control elicited significant increases in both the P3 amplitude and the self-reported negative mood. Replicating the results of the previous preexposure study, these effects were significantly reduced by the preexposure to an independent social threat (here: social exclusion). In contrast to previous findings, these effects were not modulated by the discontinuation (EG1disc, n = 25) or continuation (EG2cont, n = 24) of the preexposure threat. Given that the P3 effect is related to the violation of subjective expectations, these results support the notion that preexposure to a specific social threat has widespread effects on the individuals' expectancy of upcoming social participation and control.

Violations of Lab-Learned Phonological Patterns Elicit a Late Positive Component.

The experimental study of artificial language learning has become a widely used means of investigating the predictions of theories of language learning and representation. Although much is now known about the generalizations that learners make from various kinds of data, relatively little is known about how those representations affect speech processing. This paper presents an event-related potential (ERP) study of brain responses to violations of lab-learned phonotactics. Novel words that violated a learned phonotactic constraint elicited a larger Late Positive Component (LPC) than novel words that satisfied it. Similar LPCs have been found for violations of natively acquired linguistic structure, as well as for violations of other types of abstract generalizations, such as musical structure. We argue that lab-learned phonotactic generalizations are represented abstractly and affect the evaluation of speech in a manner that is similar to natively acquired syntactic and phonological rules.
