Happiness is no more than a pleasant mental state that we can feel everyday. How to seek happiness is the key subject of positive psychology, for which we also need a clear neural system so that our emotional life can be accomplished. This is an issue in people with neural problems (such as psychopathy or hypochondria) as they can not achieve such emotional clarity. In this sense neuroscience is thought of as a new approach that can replace the traditional rational insight which has been aimed at completing a virtual life. But there is also a limit: we can not reach a virtual life with only a confirmation of our transitive state. A practice of virtue which our moral ethos aims at, has been a problem of rational insight. Here is a gap between our emotional life and our rational insight in which an anguish of psychology results. So a task we should combine organically is band between neuroscientific fact and ethical practice; a new addition to psychology. But unfortunately psychology can not solve this problem by itself, for it is a meta-question arising beyond psychology. Thus an explication of this meta-question is, I believe, a new theory of moral philosophy; one that can only be explored using an interdisciplinary approach.

Objectives: This study investigated the relationship between clock-drawing test (CDT) performance and neuropsychological functions in patients with chronic schizophrenia. Methods: Thirty-one patients with schizophrenia and 30 healthy controls participated in this study. The CDT was administered in three conditions and analyzed using both quantitative and qualitative scoring systems. Comprehensive neuropsychological tests were administered. Results: The results of the quantitative analysis showed that the schizophrenia group performed significantly worse in all three conditions of the CDT compared with the control group. However, no significant differences were observed between the two groups, when the IQ and educational level were controlled. The qualitative analysis showed that the schizophrenia group exhibited significantly more errors in "graphic difficulty" compared with the control group. In addition, CDT quantitative scores were significantly correlated with visuospatial function, memory, attention and executive functions in patients with schizophrenia. Conversely, each qualitative error type was correlated with specific cognitive domains. Furthermore, "graphic difficulty" and "spatial/planning deficit" were identified as predictors of depression symptoms in patients with schizophrenia. Conclusion: The present study demonstrated that the CDT is useful for assessing cognitive dysfunctions in patients with schizophrenia, while qualitative analyses provide more specific information about cognitive deficits compared with quantitative analyses.

The goal of neuropsychological tests is to identify the neuropsychological dysfunction in psychiatric disorders such as organic mental disorders and schizophrenia, to develop the exe-cutive and monitor treatment plan and to make a cognitive rehabilitation program. Also, it will provide a more useful information that neurpsychological tests will be applied to neurotic out-patients in combination with conventional psychological test. However, many researches should be performed to further clarify the usefulness of neuropsychological test in neurosis.

Schiophrenia is characterized by a variety of cognitive dysfunctions. A number of research findings suggest that schizophrenic patients have global deficits in cognitive functions, such as attention, memory, executive functions, and motor functions. These cognitive deficits, once they arise, tend to become relatively stable. In spite of much efforts to search for the cognitive dysfunctions in schizophrenia, there are no specific deficits or localizations found. It is necessary that future neuropsychological research of schizophrenia should include relationships between symptoms and cognitive dysfunctions and their relationships to treatment.

First, the author reviewed the relationship between human brain development and cognitive functions such as attention, perception, memory, and language. And then Luria's neurodevelopmental theory and its application on the Neuropsychological test battery for children were reviewed. Finally, various assessment tools to evaluate attention, intellectual function, visual-perception, visual-motor coordination, and executive function were examined.

최근 들어 인공지능과 뇌과학 분야의 연구성과를 힘입어 뇌의 기본기능을 이해하고 재구축하고자 하는 시도가 활발히 전개되고 있다. 뇌의 정보처리 기능을 실험관찰 방법으로 밝히고자 하는 신경과학, 마음의 정보 처리 기능을 역시 실험관찰 방법으로 이해하고자 하는 심리학, 그리고 정보처리모형의 구성법을 제시하는 컴퓨터과학을 통합함으로써 뇌와 마음의 작동을 정보과학의 입장에서 해명하고자 하는 접근방식이 현재 가장 가능성이 있다고 생각된다. 본 논문에서는 그와 같은 맥락에서 인공적으로 뇌를 구현하기 위하여 제안된 CAM-Brain을 소개하고, 로봇을 제어하는 문제에 적용한 예를 통하여 그 가능성을 보이고자 한다.

Objectives The Behavioral Activation of Depression Scale (BADS) has been reported to be a valid tool for assessing the different behavioral aspects of depression, such as activation, rumination or avoidance, and functional impairment. The aim of this study was to assess the reliability and validity of the Korean version of BADS (K-BADS). Methods A sample of 196 outpatients completed the K-BADS and the data were analyzed for internal consistency and factor structures. An additional 51 outpatients re-filled the K-BADS after two weeks for the test-retest reliability. To test for the validity, the Hospital Anxiety and Depression Scale (HADS), Working Alliance Inventory (WAI), Drug Attitude Inventory-10 (DAI-10), and Mindfulness Attention Awareness Scale (MAAS) were administered. Results Internal consistency of K-BADS was good (Cronbach's alpha=0.843) and principal component factor analysis revealed the four-factor structure. The K-BADS showed a reasonable test-retest reliability (r=0.863, p<0.001). The total score of K-BADS correlated significantly with the total scores of the HADS depression (r=-0.694) and HADS anxiety (r=-0.681). No correlations were found between the K-BADS and the K-WAI (r=0.170) and between the K-BADS and the K-DAI-10 (r=0.311). Conclusion The K-BADS is a reliable and valid instrument for measuring the behavioral activation for depression in Korean patients with depressive symptoms.

Early diagnosis and intervention of dementia is critical to minimize future risk and cost for patients and their families. The purpose of this study was to develop and validate Figure-Copy Test(FCT), as a new dementia screening test, that can measure neurological damage and cognitive impairment, and then to examine whether the grading precesses for screening can be automated through machine learning procedure by using FCT imag es. For this end, FCT, Korean version of MMSE for Dementia Screening (MMSE-DS) and Clock Drawing Test were administrated to a total of 270 participants from normal and damaged elderly groups. Results demonstrated that FCT scores showed high internal constancy and significant correlation coefficients with the other two test scores. Discriminant analyses showed that the accuracy of classification for the normal and damag ed g roups using FCT were 90.8% and 77.1%, respectively, and these were relatively higher than the other two tests. Importantly, we identified that the participants whose MMSE-DS scores were higher than the cutoff but showed lower scores in FCT were successfully screened out through clinical diagnosis. Finally, machine learning using the FCT image data showed an accuracy of 73.70%. In conclusion, our results suggest that FCT, a newly developed drawing test, can be easily implemented for efficient dementia screening.

This study deals with exploring qualitative steps and paths that appear as YouTube users' usage time increases quantitatively. For the study, I applied theories from psychology and neuroscience, subdivided the interval between the personalization algorithm of the recommendation system, and active use and analyzed the relationship between variables in this process. According to the theory behavioral model theory (FBM), variable reward, and dopamine addiction were applied. Personalization algorithms easy clicks as triggers according to associated content presentation functions in behavioral model theory (FBM). Variable rewards increase motivational effectiveness with unpredictability of the content you search, and dopamine nation is summarized as stimulating the dopaminergic nerve to continuously and actively consume content. This study is expected to make an academic and practical contribution in that it divides the purpose of use of content in the personalization algorithm and active use section into four stages from a psychological perspective: first use, reuse, continuous use, and active use, and analyzes the path.
