In this paper, objectively quantified consonance of complex sound is proposed as a new psychoacoustical parameter. Proposing algorithm quantifies consonance of complex sound after applying psycho acoustical models which are parts of human perception such as masking effect, equal loudness contour, and critical band. To verify proposing algorithm, experiments with 10 car horn signals which have different complex sound were performed. The experiments show cross correlation of 0.95 between objectively quantified consonance by proposing algorithm and subjectively assessed consonance by listening tests. Considering the fact that there are few psychoacoustical parameter except Zwicker parameter, proposing algorithm will help to quantify psychoacoustical effect of complex sounds objectively.

The purpose of this study was to examine the correlations among empathy, humor sense parenting self-efficacy and psychological control in Korean parents with a child. For research, 203 parents with a child under the age of 5 attending kindergarten in Seoul participated in this study. As a result of the study, parenting self-efficacy was the lowest and psychological control was the highest. In adittion, among 'empathy', 'humor sense' and 'autonomy support', 'guilt inducement' on sub factor of psychological control showed a significant correlations. In addition, 'cognitive empathy' on sub factor of empathy was significantly correlated with 'autonomy control' on sub factor of psychological control, and 'preference for humor' on sub factor of humor was significantly correlated with 'identical parenting' on sub factor of psychological control. Among parenting self-efficacy and 'autonomy support', 'guilt inducement', 'autonomy control' on sub factor of psychological control showed a significant negative-correlation. 'Difficulty in parental roles' on sub factor of parenting self-efficacy was negatively correlated with other factors except 'identical parenting' on sub factor of psychological control.

Objectives : We investigated the characteristics of perceived stress response and relationship between some variables of gastrointestinal symptoms(esp., dyspepsia) and subscales of perceived stress response inventory(PSRI) in patients with upper gastointestinal disorder when they perceived stress. Methods : 84 patients with upper gastrointestinal disorder(gastritis, gastric ulcer, duodenal ulcer etc.) and 94 normal controls completed the PSRI developed by Korean psychiatrists. The patient group performed the questionnaire including some variables of gastrointestinal symptoms. Results : Internal consistency was statistically significant in all subscales of PSRI. The patient group was significantly higher at total score of PSRI, general somatic symptom subscale score, specific somatic symptom score than control group. As the result of stepwise regression analysis for relationship between some variables of gastrointestinal symptoms ans subscales of PSRI, specific somatic symptom subsclae closely related with illness duration, past illness history and severity of symptom, and the lowered cognitive function & general negative thinking subscale related with the existence of emotional distress. Conclusion : Patients with upper gastrointestinal disorder showed stronger perceived stress response than control group and they experiences somatic symptoms related to autonomic nervous system and/or gastrointestinal symtoms rather than emotional, cognitive, behavioral symtoms when they perceived stress. They also responded to stress as they expeirenced specific somatic symtom when they had long illness duration, past illness history, and high severity of symptom and the existence of emotional distress could develop lowered congnitive function and general negative thinking.

Recent research has shown that university students experience severe stress and depleted directed attention due to study, social relationships, and economic dependency. Based on the stress reduction theory and the attention restoration theory, this study aims to investigate the effects of natural landscape on university students' stress and cognitive performance through a wide array of measurements including GSR(galvanic skin responsse), IBI(interbeat interval), ZIPERS(Zucherman Inventory of Personal Reactions), and mental arithmetic test. The restorative effects of natural landscape were compared with those of urban landscape. 128 university students participated in the study, and the data of 120 students was analyzed. The results showed that natural landscape was more restorative in relieving psychological stress and in enhancing cognitive performance than urban landscape, which evidenced the restorative effects of natural landscape. Therefore, it could be proposed that natural landscaping of the university campus contributes to students' stress reduction and cognitive enhancement. But such effects were not found in the two physiological measures(both GSR and IBI). Moreover, it was analyzed that urban landscape had a more beneficial effect than natural landscape for IBI, which might resulted from the participants' characteristics and the study landscape. Specifically, the young age span of the participants(average 23.8 years old) and the very natural setting of the university where they were enrolled might lead to the conflicting results in physiological measures. Also, the urban landscape used in the study had a sense of "scope", which is one of the Kaplan and Kaplan's restorative characteristics. Based on this opinion, it was suggested that future study should investigate the impact of the landscape type and contents as well as the participants' characteristics on the restorative effects of natural landscape.

The purpose of this study is to verify the effect of the civil servant superior's coaching leadership on the innovation behavior and cooperative behavior of organizational members of public institutions. And it examines the mediating roles of subordinates' cognitive flexibility and belief of the colleague's potential growth in the relationship between coaching leadership and subordinates' innovative and cooperative behaviors. As a result of the study, first, it was confirmed that the coaching leadership of civil servant superior had a significant positive effect on the innovative and cooperative behaviors of subordinates. Second, it was verified that the superior's coaching leadership had a positive effect on the cognitive flexibility of subordinates and the belief of the colleague's potential growth. Third, it was confirmed that cognitive flexibility mediates between the superior's coaching leadership and innovative behavior. Fourth, it was not significant that the belief of the colleague's growth potential mediates between the superior's coaching leadership and cooperative behavior.

The purpose of this study was to investigate Korean undergraduate students' metacognitive awareness and preference of effective learning strategies. To achieve this goal, a scenario-based survey was conducted focusing on the metacognitive awareness, preference, and use of seven effective learning strategies (modality effect, static-media presentations, absence of extraneous details, testing, distributed learning, interleaved learning, generation) that were empirically supported. This study also aimed to explore the relationships between grade point average (GPA), metacognitive self-regulation, and the aforementioned variables to investigate which students know about, prefer, and use effective learning strategies. The majority of students were unknowledgeable about four of the seven strategies (modality effect, static-media presentations, absence of extraneous details, interleaved learning). Only half of the students were correctly aware of effectiveness of the two strategies (testing, generation). Moreover, students showed low preference for effective learning strategies. GPA did not show a significant correlation with metacognitive awareness and preference of effective learning strategies; however, it showed a significant positive correlation with the use of effective learning strategies. Only for a few learning strategies, metacognitive self-regulation showed a positive correlation with metacognitive awareness, preference, and/or their use. This study suggests that it is important to teach effective learning strategies to undergraduates with a specific direction of instruction. In addition, this study distinguishes metacognitive awareness from preference, suggesting that these two may reflect different constructs.

The purpose of this study is to propose optimized cognitive warfare strategies for the Korean Peninsula by analyzing recent war case studies. Through the analysis of the Armenia-Azerbaijan war, the Israel-Palestine conflict, the Ukraine-Russia war, and the Israel-Hamas conflict, it was found that the following aspects are crucial in conducting cognitive warfare: 1) applying methods according to objectives, 2) organizing and structuring appropriately to the objectives and means, and 3) utilizing various means from both civilian and military sectors. Based on these findings, cognitive warfare strategies optimized for the operational environment of the Korean Peninsula were suggested in terms of the three elements of military innovation. From the aspect of methodology, it is recommended to develop cognitive warfare scenarios based on legitimacy and legality, and to integrate roles according to the level of warfare. Regarding organization and structuring, the establishment of a national-level control tower and the construction of an integrated response system involving civilians, government, military, and police based on legislation are proposed. In terms of means, it is suggested to utilize various tools from the civilian, government, military, and police sectors, such as North Korean defectors, psychological warfare broadcasts against North Korea, social media, and cyber operations, for auditory, visual, and message delivery. In future battlefields characterized by hyper-connectivity and hyper-intelligence, the execution of cognitive warfare will become increasingly important. Therefore, it is necessary to continuously develop optimized cognitive warfare strategies for the Korean Peninsula through comprehensive national efforts.

This study was carried out to examine whether children had the naive psychological knowledge that the mental states ate requited to understand the intentional actions, whether their psychological knowledge was organized as a theory, and in what aspects the knowledge changed as children get older. Three- to 11-year-olds were presented with two types of tasks. In action explanation tasks, children were presented with simple descriptions of two characters engaging in specific actions and then asked to explain the characters' action. In action prediction tasks, they were told stories depicting a character's desire and belief and then asked to predict the action of the character. Three-year-olds explained the action in terms of abstract construct such as emotion, intention, and desire, and they predicted the character's action on the basis of her/his desire and explicit belief but not on the basis of inferred false belief and traits. In addition when they were asked to explain one mental state, they explained in terms of other mental states, suggesting the coherence of their knowledge. The present results suggested that even 3-year-olds' psychological knowledge was organized as a theory, in that it was used as a causal device in explaining and predicting human actions, and it had abstractness and coherence. Older children's knowledge was different from 3-year-olds' in that older children explained the action in terms of more complicated mental states such as beliefs and traits. The nature of the developmental change in psychological knowledge was discussed.

This study investigated the navigation ability of patients with MCI in Virtual Environments(VE) and on the visual functioning. The participants consisted of elderly adults with/without MCI. Neuropsychological tests(RCFT, BVRT, TMT, and Digit Span), the Groton Maze Learning Test(12trials), and the VE navigation learning task(6 trials) were performed. As a result, there were significant group differences for the RCFT and BVRT, but not for the GMLT. For the VE task, there was a significant difference between the MCI and normal group and no interactions between the groups and trials were found. The VE task was correlated with The RCFT, the BVRT, and the GMLT and omnibus the RCFT and the BVRT accounted for 45% of VE performances. Thus, we concluded that patients with MCI are inferior to VE navigation and visual retention/memory play a role in navigation abilities.
