Objective: Cyberbullying is increasing every year and poses a serious problem worldwide; although the rate of adult cyberbullying is increasing every year, still cyberbullying studies mainly focused on youths. This study examined the moderating effect of Internet ethics on the relationship between cyberbullying victimization and perpetration among adults. Methods: An online self-report survey was conducted with 601 participants aged 20 to 59. A final total of 593 participants were included in the analysis. Confirmatory factor analysis of the Internet Ethics Scale was performed using AMOS 22.0, and the moderating effect was verified using PROCESS Macro v3.5. Results: First, cyberbullying victimization was found to positively predict perpetration. These results indicate that the higher the cyberbullying victim experience, the more the cyberbullying behavior increases. Second, the moderating effect of Internet ethics on the relationship between cyberbullying victimization and perpetration was significant. Third, in the relationship between cyberbullying victimization and perpetration, the moderating effects of respect, responsibility, justice, and non-maleficence, which are subfactors of Internet ethics, were found to be significant. Conclusion This study demonstrated the preventive effect of Internet ethics on the relationship between cyberbullying victimization and perpetration among adults. Based on this, a theoretical basis for the intervention of education and programs for adult cyberbullying prevention was provided.

Objective: This study investigated the mediating effect of loneliness on the relationship between anhedonia and suicidal ideation, and the moderated mediating effect of emotional intelligence on the relationship between loneliness and suicidal ideation. Methods: Participants (390 adults; males=194, females=196) aged between 19–59 years completed self-report questionnaires. Frequency and descriptive statistics, correlation analysis, mediating effect analysis, moderating effect analysis, and moderated mediating effect analysis were conducted using SPSS Statistics version 23.0 and the PROCESS Macro for SPSS version 4.2. Results: Loneliness partially mediated the relationship between anhedonia and suicidal ideation. Additionally, emotional intelligence and its four subfactors moderated the relationship between loneliness and suicidal ideation. Finally, emotional intelligence and its subfactors (self-emotional appraisal, others’ emotional appraisal, emotion utilization) moderated the mediating effect of anhedonia on suicidal ideation through loneliness, verifying the moderated mediating effect. Conclusion It clarified the path that anhedonia has on suicidal ideation and confirmed the role of emotional intelligence.

Purpose: This study evaluated the postoperative quality of life (QoL) after various types of gastrectomy for gastric cancer. Materials and Methods: A multicenter prospective observational study was conducted in Korea using the Korean Quality of Life in Stomach Cancer Patients Study (KOQUSS)-40, a new QoL assessment tool focusing on postgastrectomy syndrome. Overall, 496 patients with gastric cancer were enrolled, and QoL was assessed at 5 time points: preoperatively and at 1, 3, 6, and 12 months after surgery. Results: Distal gastrectomy (DG) and pylorus-preserving gastrectomy (PPG) showed significantly better outcomes than total gastrectomy (TG) and proximal gastrectomy (PG) with regard to total score, indigestion, and dysphagia. DG, PPG, and TG also showed significantly better outcomes than PG in terms of dumping syndrome and worry about cancer. Postoperative QoL did not differ significantly according to anastomosis type in DG, except for Billroth I anastomosis, which achieved better bowel habit change scores than the others. No domains differed significantly when comparing double tract reconstruction and esophagogastrostomy after PG. The total QoL score correlated significantly with postoperative body weight loss (more than 10%) and extent of resection (P<0.05 for both).Reflux as assessed by KOQUSS-40 did not correlate significantly with reflux observed on gastroscopy 1 year postoperatively (P=0.064). Conclusions Our prospective observation using KOQUSS-40 revealed that DG and PPG lead to better QoL than TG and PG. Further study is needed to compare postoperative QoL according to anastomosis type in DG and PG.
