This essay studied the acting theories of Diderot, Delsarte, Meyerhold, and Artaud to know the historical formation of 'sign acting' and its theoretical and aesthetic appropriateness. The sign acting so far discussed shows the repetitive patterns of idea as follows. The sign acting (1) emphasizes the physical expression such as gesture and movement, (2) assumes that the physical expression functions as a sign evoking special emotion and thought, (3) thus recommends the imitation of the outer sign, (4) uses a tableau for the effective reception of outer sign, (5) aims for the spectator oriented aesthetics as it stresses the result of outer sign rather than the creative process of a role, (6) assumes that the emotional reaction or the intellectual understanding springs from the physical experience, (7) thus emphasizes the physical language rather than speech, (8) can attain the appropriateness of physical language by the recent theories of cognitive science. Besides having such commonness, the sign acting also reveals the individual differences. For instance, the intended sign for Diderot and Delsarte was the sign of emotion, for Meyerhold the stylized sign of circus and acrobatics, and for Artaud the spiritual sign. If Diderot and Meyerhold demands the cool consciousness for the correct sign acting, Artaud's sign acting tends to pursue the state of trance. And if Diderot, Delsarte, and Meyerhold think the sign acting on the level of sensory appeal, Artaud insists that the sign acting should dismantle the spectator's sense. As such the discussion of sign acting shows both recurrent ideas and new visions, forming an unity out of diversity. Perhaps the sign acting is a matter of practice before we consider it as a theory. It is not only supposed to have been existed practically since ancient theatre, but also used by actors consciously and unconsciously in expressing certain emotion and thought. We need to study the sign acting more academically, considering its long history and aesthetic potentials. In fact the sign acting has been an essential element of acting, in spite of bad reputation judging it as a banal and worn-out style. It is true that the sign acting, in the worst case, could produce a stereotypical expression. It was this aspect of sign acting that caused a fierce negative reaction of the realists who sought the natural expression based upon psychological truth. Of course the sign acting has a serious problem when it stays banal and artificial. But we need to see this issue from a different perspective. What is the natural expression of emotion? How is it free from the learned way of expression? In some respect, we use, in reality, a learned expression of emotion that could be accepted socially. For instance, when we attend a funeral, we use the outer sign of mourning gestures learned socially. If a semiotic expression pervades various aspects of our life, the acting, being the representation of life, seems not to be free from codified expression. The sign acting could be used consciously and unconsciously in all kinds of acting.

본 연구에서는 fMRI 기법을 이용하여 경쟁 상황 노출 여부에 따라 개인이 타인의 상황을 이해하고 인지적 공감을 유발하는 신경학적 기제의 차이를 조사하였다. 공감은 타인에 대한 이해를 바탕으로 적절한 반응을 보이는 심리적 반응이며, 인간의 생존에 있어서 적응적 요소로 알려져 있다. 연구의 목적은 Preston과 de Waal(2002)에 기초하여 거의 자동적인 반응인 공감이 타인을 이겨야 하고 본인의 수행에 따라 보상이 달라지는 경쟁 상황에서도 1) 타인이 처한 상황을 인지할 수 있는지, 2) 인지한다면 인지적 공감이 유발되는지를 확인해 보는 것이다. 대학생 21명(남:여=9:12)을 대상으로, 일상생활에서 경험할 수 있는 6가지 정서가 제시된 그림자극을 보고 '나'의 관점에서 유발되는 정서가 긍정정서인지 부정정서인지 평정하는 과제 수행동안 뇌 활성화를 촬영하였다. 경쟁 유무에 따라 공감과정에서 두뇌 활동의 차이를 비교하기 위해 실험보조자 1인이 경쟁자 역할을 수행하고, 수행 결과의 정확도와 반응 시간을 기준으로 피험자가 경쟁자(실험보조자)를 이길 경우 보상(돈)을 제공하는 조건으로 경쟁심을 유발하여 경쟁 조건을 조작하였다. 연구결과, 피험자들의 판단 반응시간은 비경쟁 상황보다 경쟁에 노출되었을 때 통계적으로 유의하게 빠름을 확인하였고, 경쟁 상황에서는 전대상회(ACC, BA 32), 내측전두엽(mPFC, BA 6), 측두두정연합부의 한 부분인 연상회(SMG, BA 40), 시상(thalamus), 중전두엽(middle frontal gyrus, BA 10) 등이 활성화 된 반면, 비경쟁 상황에서는 인접대상회(paracingulate, BA 32), 측두엽극(temporal pole, BA 38), 복내측전전두엽(vmPFC, BA 11), 상후두엽/쐐기소엽(superior occipital gyrus/cuneus, BA 19) 등의 영역에서 활성화가 관찰되었다. 또한 경쟁상황에서 개인의 공감 수준에 따라 두뇌 영역과의 상관을 알아보기 위해 공감에 대한 자기 보고식 반응 점수를 공변량으로 이용하여 중다회귀분석을 실시한 결과, 경쟁 상황에서는 우측 연상회(rSMG, BA 40), 하전두엽(inferior frontal gyrus, BA 47/45), 내측전두엽(mPFC, BA 10/6), 시상(thalamus), 피각(putamen), 방추형회(fusiform gyrus, BA 20/21)영역과의 상관이 높은 반면, 비경쟁 상황에서는 공감 수준이 높을수록 측두두정연합부/상측두엽(temporoparietal junction/superior temporal gyrus) 영역이 높은 상관을 보였다. 이 연구의 결과를 통해 경쟁 노출 여부에 따라서 타인에 대한 공감적 인지과정에 서로 다른 두뇌영역이 사용되며, 특히 개인의 공감 수준이 높을수록 경쟁 상황에서도 타인의 상황에 대해 이해하는 인지적 공감과 관련한 두뇌 영역이 높은 상관을 보여 개인차에 따라 경쟁 지각이 다르게 반응함을 알 수 있었다.

Objectives : Phencyclidine(PCP) or PCP-like substances such as ketamine have been known to rekindle the cognitive dysfunction in schizophrenia. The aims of this study were to identify whether PCP-like substances can produce cognitive deficit in schizophrenia, to discuss relation with aging process, and finally to speculate underlying neurochemical mecha-nisms by various drug responses. Methods : In experiment I, radial maze tests were done in 24 Sprague-Dawley rats for 3 days to get baseline data. Being divided into 4 groups(6 rats respectively) of normal aged, normal adult controls, atropine-treated and ketamine-treated, the radial maze tests were repeated on every week for 6 weeks, and then the rats were sacrificed by intracardiac perfusion with phosphate-buffered 10% formaldehyde solution for histology. The brain specimen was stained with hematoxylin-eosin to count cells in the prefrontal cortex and hippocampus. In experiment II, radial maze tests were done for 48 rats before any drug treatment and only after ketamine administration. Thereafter, haloperidol, bromocriptine, clonidine, nimodipine, tacrine, valproic acid, naloxone and fluoxetine were intramuscularly injected on every other day in addition to ketamine. Radial maze tests were repeated on every week for 6 weeks, and then rats were prepared by the same procedure for histology. Results : 1) Reaction times of radial maze tests of atropine-treated rats were significantly prolonged than those of normal aged(p<0.05) or normal adult controls(p<0.05). Cell numbers of prefrontal cortex & hippocampus in ketamine-treated rats were significantly reduced than those in normal aged (p<0.05) or normal adult controls(p<0.005). 2) Reduced cell numbers by ketamine became significantly raised by tacrine administration in prefrontal cortex & hippocampus(p<0.05), while there were no significant changes on radial maze tests. Cell numbers also tended to be raised by nimodipine, fluoxetine and haloperidol administration. Conclusions : In conclusion, the visuospatial memory disorders in ketamine-induced psychotic rats might be partly asso-ciated with aging process. Furthermore, the responses to the various drugs suggested cholinergic system might have an important role in the neurochemical mechanism of the cognitive dysfunction in ketamine-induced psychosis. Otherwise, calcium metabolism as well as serotonergic and dopaminergic systems seemed to be possibly related.

In order to reduce the social and economic costs due to the increase in dementia patients, which is a representative senile disease in an aging society, it will be important to prevent dementia and to detect and treat early in high-risk groups. This study reported the results of treatment for the elderly with high risk of dementia and depression who received Korean medicine (KM) treatment in 9 KM clinics. Medical charts were surveyed on 116 patients with high risk of dementia and depression who received KM treatment at 9 KM clinics in Gangseo-gu from September 1, 2020 to December 31, 2020. The majority of the patients were female(76.72%), the average age was 71.66±7.18 years old, and the average education level was 8.96±3.91 years. The average treatment period was 61.47±10.30 days, the average number of treatments was 15.38±1.06 times, and both acupuncture and herbal medicine were administered. After receiving KM treatment, cognitive assessment scores such as MMSE-DS and MoCA-K, depression-related GDSSF-K score, dementia knowledge, attitude, and preventive behavior, blood debilitation scale, and GQOL-D score were improved compared to before. There was no specific adverse reaction except that one patient with elevated AST and ALT levels was observed. This study showed improvement in cognitive function, depression, dementia-related scale, and quality of life in high-risk groups for dementia and depression over 60 years old who received KM treatment. More systematic and large-scale planned clinical studies will be needed.

As the modern society is called the narcissistic society, the narcissism is widespread in the personality of individuals and the society at large. In consideration of this side, this study explored for several characteristics of the narcissistic personality and the job stress, and explored for the relationships between the two things theoretically. The narcissism is an attempt to repair self-esteem weakened by the splitting anxiety, the lack and the pathological fusion of self-structure. The job stress is a factor that a characteristic of the job influenced on the behavioral and affective response of the person on the job directly or indirectly. This study selected organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development as factors of the job stress. This study viewed that the stress is made from an interaction between environmental stimulus and personal particular reaction by defining the stress as an interaction model of stimulus-response and personal reaction is caused by psychological adjustment process, personal differences. On this occasion, this study discussed that the narcissistic personality is easy to get stress and weak in the job stress with regarding the personality as a mediation variation of psychological process. As a result, the narcissists estimated themselves positively and their self-esteem is high, but they excessively showed a self biased cognitive and affective response about the negative feedback to protect themselves. Moreover, this positive estimate on themselves and high self-esteem was vulnerable and weak in the self threat. In this view, the narcissistic personality is easy to get more job stress such as organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development.

Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.

The event-related potentials are difined as the changes in voltage that occur at paticular time before, during and after something that happens in the physical world or some psychological processes. The possibilities of clinical applications of ERP are considered because the endogenous potentials such as P3 and contingent negative variation(CNV) are determined by the psychological significance of the stimulus. The P3 is a positive wave that occurs when a subject detects an informative task-relevant stimulus. The P3 amplitude and latency are affected by the various factors as subjective probabilites, stimulus meaning and information transmission. It is suggested that P3 wave is associated with the decision making, cognitive or perceptual closure, memory updating and transfer of information to consciousness etc. Although the intracerebral origin of the P3 wave is not known, the P3 may have multiple intracerebral generators. The CNV is a slow potential shift occuring during the foreperiod, between warning and response signals, in a reaction time experiment. It is related to expectancy, preparation etc. The abnormal findings of P3 wave and CNV in various psychiatric disorders are also discussed.

The purpose of this study was to investigate the effects of training and use of worked-example on chemical problem-solving learning. Schema acquisition and rule automation are the basic components of skilled problem-solving, which are dependent on appropriately focused attention and sufficient cognitive resources. Training and use of worked-example facilitate schema acquisition and rule automation, so improve problem-solving learning. The subjects of this study were 60 high school students. The average age was 17 years old. Then, they were randomly assigned to each groups and the chemical reaction problems used as experimental materials. The independent variables of this study were training and use of worked-examples and dependent variables were time for solution and the number of error. The results of this study were as follows; 1. The worked-example groups spent significantly less time on solution for acquisition problems than the conventional problem groups. 2. The long-acquisition groups spent significantly less time on solution for acquisition problems than the short-acquisition groups. 3. The modified worked-example groups did not spend significantly less time on solution for acquisition problems than the worked-example groups.
