The purpose of this study is to find out the relation between co-cognitive factors, personal affective and characteristic features as the basis that prompts talented behaviors and leadership. The subjects of the study were 77 elementary mathematically gifted students attending at the gifted education center affiliated with University of Education in D metropolitan city and 110 elementary students in metropolitan city and provinces. The results of this study are as follows. First, elementary mathematically gifted students had higher levels than general students in every subdirectory of co-cognitive factors and the difference was statistically significant. Second, there was a difference between leadership of elementary mathematically gifted students and that of general students. Also, the level of gifted students' leadership was higher than the latter. Third, when it comes to the relation between co-cognitive factors and leadership, both of gifted students and general students showed positive correlation between subdirectory of co-cognitive factors and that of leadership. Consequently, development of co-cognitive factors will lead to improvement of leadership since co-cognitive factors positively influence on leadership. Therefore, it is desirable that co-cognitive factors are considered when developing a program for leadership.

This study focused on finding how to raise the positive effect of a service employee on the organization by strengthening his sympathetic feeling at the position of business, not the position of customer and how to reduce the negative effect. The specific objectives of the study are: First, the effect factors of the empathy abilities (cognitive empathy, emotional empathy) of a service employee are largely classified as the social support (supervisor support, co-worker support) to the service employee and the self-soothing ability. Therefore, this study tries to verify the relationship between the self-soothing ability, and social support and empathy which are preceding factors of the empathy of a service employee. Second, it also tries to verify the relationship between job stress and empathy ability(cognitive empathy, emotional empathy) of a service employee. As a result of the verification of the study hypothesis, first, the social support was distinguished as supervisor support and co-worker support, and the empathy ability was distinguished as cognitive empathy and emotional empathy. As a result of verifying the relationship between social support and empathy ability, the supervisor support did not have a positive effect on cognitive empathy while the co-worker support did have a positive effect of cognitive empathy. The supervisor support had a positive effect on emotional empathy and the co-worker support had a positive effect on emotional empathy. Second, the self-soothing ability of a service employee had a positive effect on empathy ability and a positive effect on both cognitive empathy and emotional empathy. Finally, the empathy ability(cognitive empathy, emotional empathy) of a service employee was shown to have a negative effect on the job stress of a service employee.

Background and Purpose: Subjective cognitive decline (SCD) refers to the self-perception of cognitive decline with normal performance on objective neuropsychological tests. SCD, which is the first help-seeking stage and the last stage before the clinical disease stage, can be considered to be the most appropriate time for prevention and treatment. This study aimed to compare characteristics between the amyloid positive and amyloid negative groups of SCD patients. Methods: A cohort study to identify predictors for the clinical progression to mild cognitive impairment (MCI) or dementia from subjective cognitive decline (CoSCo) study is a multicenter, prospective observational study conducted in the Republic of Korea. In total, 120 people aged 60 years or above who presented with a complaint of persistent cognitive decline were selected, and various risk factors were measured among these participants. Continuous variables were analyzed using the Wilcoxon rank-sum test, and categorical variables were analyzed using the χ² test or Fisher's exact test. Logistic regression models were used to assess the predictors of amyloid positivity. Results: The multivariate logistic regression model indicated that amyloid positivity on PET was related to a lack of hypertension, atrophy of the left temporal lateral and entorhinal cortex, low body mass index, low waist circumference, less body and visceral fat, fast gait speed, and the presence of the apolipoprotein E ε4 allele in amnestic SCD patients. Conclusions: The CoSCo study is still in progress, and the authors aim to identify the risk factors that are related to the progression of MCI or dementia in amnestic SCD patients through a two-year follow-up longitudinal study.

Self-reported difficulties in speech-in-noise (SiN) recognition are common among tinnitus patients. Whereas hearing impairment that usually co-occurs with tinnitus can explain such difficulties, recent studies suggest that tinnitus patients with normal hearing sensitivity still show decreased SiN understanding, indicating that SiN difficulties cannot be solely attributed to changes in hearing sensitivity. In fact, cognitive control, which refers to a variety of top-down processes that human beings use to complete their daily tasks, has been shown to be critical for SiN recognition, as well as the key to understand cognitive inefficiencies caused by tinnitus. In this article, we review studies investigating the association between tinnitus and cognitive control using behavioral and brain imaging assessments, as well as those examining the effect of tinnitus on SiN recognition. In addition, three factors that can affect cognitive control in tinnitus patients, including hearing sensitivity, age, and severity of tinnitus, are discussed to elucidate the association among tinnitus, cognitive control, and SiN recognition. Although a possible central or cognitive involvement has always been postulated in the observed SiN impairments in tinnitus patients, there is as yet no direct evidence to underpin this assumption, as few studies have addressed both SiN performance and cognitive control in one tinnitus cohort. Future studies should aim at incorporating SiN tests with various subjective and objective methods that evaluate cognitive performance to better understand the relationship between SiN difficulties and cognitive control in tinnitus patients.

The aim of this research is to find out the common emotional factors that elementary school teachers feel when they experience in teaching children with ADHD and to know their responding process through experiential analysis. Seven elementary school teachers took part in this research as co-investigators, and I led the experiential approach. The co-investigators have analyzed their emotional experiences during 4 sessions. They learnt about the method of experience analysis and discussed their emotional experiences of children with ADHD. And they found out some factors concerning their emotional experiences and had the time to discuss in odor to search for the common factors of that process. Finally the co-investigators took part in a session to examine the factors which they have all agreed in, and then I verified this result. 1 interpreted the factors found and constructed a psychological resolution process. Two main objectives and the results of this research are as follows. First, are there any common factors among teachers who experience in treating children with ADHD? This research showed that elementary school teachers get angry and irritated with ADHD children's troubles. Second, what kind of psychological process is there in teachers' experiences children with ADHD? The psychological process of teachers dealing children with ADHD could be conceptualized in 5 steps, the step of recognizing an action of children with ADHD, the step of first cognitive consideration, the step of giving meaning and cognitive appraisal, the step of experiencing emotion, and the step of dealing with emotion. Teachers seemed to experience a little bit different psychological process. According to whether they thought about children's behavior positively or negatively in the second step, they had different emotional experiences. If they had a positive thought, they could take children's nonadaptive behaviors as personal characteristics. However, if they took them negatively, they considered them impolite and disobedient. Even when the teachers experienced negative emotions, their responses were divided into two groups whether they took it positively or negatively. This research showed that if teachers could control their negative emotional experiences, they could calm down with children with ADHD and treat them positively.

Objective : The aims of this study were to investigate the prevalence of co-morbid depression and related factors of depression in mild cognitive impairment (MCI) patients. Methods : Nine hundred and six MCI individuals were included in this study. Depression was defined as major and minor depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). Depression-related demographic and clinical factors were also explored through multivariate logistic regression analysis. Results : In MCI patients, the prevalence of depression as defined according to the DSM-IV diagnostic criteria was 1.8% for major depressive disorder, 11.4% for minor depressive disorder, and overall 13.2% for both. Multivariate logistic regression showed that increased prevalence of overall depression was associated with female gender and non-amnestic subtype of MCI. Conclusion : Our findings based on a large number of MCI subjects who visited memory clinic indicated that more than ten percent of MCI patients have comorbid depression. In addition, female and non-amnestic subtype of MCI patients seems to be more vulnerable to depression.

The purpose of this study was to identify between the successful aging-related predictive factors and the successful aging in the middle aged office. The predictive factors of successful aging such as subjective health condition, cognitive functions, self-esteem, and social support were confirmed by the existing literature. The population of the study was the middle aged office employees, who are generally defined an age group from 40 to 60. The sample of this study was targeted to employees working at companies registered to securities, KSDAQ, and KONEX in Korea. SPSS WIN 23.0 and AMOS 21.0, and M-plus 6.12 were used for the data analysis. The findings of this study were presented below. First, the result of the structural relationship between the predictive factors of successful aging (subjective health condition, cognitive function, self-esteem, and social support) and successful aging was appropriate as RMSEA=.059, TLI=.932, CFI=.944. Second, subjective health condition and social support were significant variables for successful aging but cognitive function and self-esteem were not significant. Third, social support, which is a social factor, was the most influential among other variables. Based on the results, theoretical and practical implications were presented.
