The purpose of this study is to propose cognitive ecological effects of fractal patterns in space design. This study investigated the perception and cognition problems regarding landscape patterns showing fractal properties from the cognitive perspective instead of the traditional speculative approach. In particular, the researcher has verified that fractal geometry theory and fractal pattern concept provide insight in space aesthetic values and cognitive effects. Research results are as follows. First, most environmentally-friendly fractal urban forms provide cognitive connectivity. In particular, this space provides a positive emotional response and preference to humans and displays self-organized complexity. This study found that such complexity of space form has characteristics corresponding to parallel cognitive structures of the human brain. Simultaneously, the researcher suggests that the fractal landscape pattern is an alternative for stiff and homogenized modern space. Second, fractal patterns provide hierarchical connectivity within the brain through continuous difference and repetition. In particular, self-similarities of fractal patterns administer significant visual grouping and coherence in human perception. It can be determined whether scaling coherence facilitates easier organization in cognitive organization. Third, fractal patterns in space design provide the basic method for achieving the connection between concept, construction, and urban factors. As a result, the researcher has suggested that scale distribution of geometrical factors, such as fractal patterns, an be a design method to connect various space typologies.

Using a psychometric paradigm, risk perception of 30 hazards was investigated for three social groups-college students, experts of technologies, and employees of environmental organizations. The aim of this study was to examine psychological dimensions of risk perception, namely, to replicate the psychological dimensions - dread and knowledge -, which Slovic et al(1978; 1984; 1987) found and to forker explore discrepancies between societal groups. The results confirmed the same psychological dimensions Slovic et al have found. However, there are a number of significant differences in perceived risk such as perceived social benefits and other risk characteristics between three groups that suggest differences in ecological attitudes. The results were compared with those of Slovic et af and the nature of differences in risk perception among three groups were discussed.

The present study investigated how one's cognitive resources are related to speech perception by examining Korean speakers' executive function (EF) capacity and its association with voice onset time (VOT) and f0 sensitivity in identifying Korean stop laryngeal categories (/t'/ vs. /t/ vs. /t^h/). Previously, Kong et al. (under revision) reported that Korean listeners (N = 154) in Seoul and Changwon (Gyeongsang) showed differential group patterns in dialect-specific cue weightings across educational institutions (college, high school, and elementary school). We follow up this study by further relating their EF control (working memory, mental flexibility, and inhibition) to their speech perception patterns to examine whether better cognitive ability would control attention to multiple acoustic dimensions. Partial correlation analyses revealed that better EFs in Korean listeners were associated with greater sensitivity to available acoustic details and with greater suppression of irrelevant acoustic information across subgroups, although only a small set of EF components turned out to be relevant. Unlike Seoul participants, Gyeongsang listeners' f0 use was not correlated with any EF task scores, reflecting dialect-specific cue primacy using f0 as a secondary cue. The findings confirm the link between speech perception and general cognitive ability, providing experimental evidence from Korean listeners.

Purpose: The aim of this study is to examine the reciprocal causal relationship between social activities and health with reference to the cognitive function level among community-dwelling older adults. Methods: We conducted a longitudinal data analysis using the $4^{th}$ (Time 1) and $5^{th}$ (Time 2) waves from the Korean Longitudinal Study of Ageing adopting cross-lagged panel analysis (CLPA). Results: A total of 3,473 community-dwelling older adults were included in the analysis: 2,053 in the normal cognitive function group, 912 in the mild cognitive impairment group, and 508 in the moderate to severe cognitive impairment group. The CLPA revealed that higher levels of social activities at Time 1 significantly influenced better subjective health perception at Time 2 in all three groups. In addition, better subjective health perception at Time 1 significantly influenced higher levels of social activities at time 2 only in the normal cognitive function group. Conclusion: This study demonstrates that participating in social activities has positive effects on health regardless of the cognitive function level in community-dwelling older adults. This finding suggests that there is a need to develop strategies that can be used to encourage older adults with cognitive decline to maintain participation in social activities.

The present study investigated children's self-perceived competence as related to (1) their perception of parental warmth and control (2) age and sex of child (3) the relationship of this perception to parents' educational level and children's sex. The subjects were 303 fourth and sixth grade children selected from three elementary schools in Seoul. The instruments were a children's self-perceived competence scale, and a perception of parental warmth and control scale. Frequencies, percentiles, mean, t-test, one-way-ANOVA, and $Scheffe{\acute{e}}$-test were used for data analysis. There were significant differences in children's self-perceived competence by perception of parental warmth and control. The children who perceived more parental warmth and control perceived themselves higher in cognitive and social competence and in self-worth. Children whose parents' were college graduates perceived highest parental warmth. Fourth grade children perceived themselves higher than sixth grade children in cognitive competence and in global self-worth. Boys perceived themselves higher than girls in physical competence. Boys perceived higher parental control than girls.

The present study examined if individual listeners' perceptual variations were associated with their cognitive characteristics indexed by the Autistic Spectrum Quotient (AQ). This study first investigated the perception of the lexical pitch accent contrast in the Kyungsang Korean currently undergoing a sound change, and then tested if listeners' perceptual variations were correlated with their AQ scores. Eighteen Kyungsang listeners in their 20s participated in the perception experiment where they identified two contrastive accent words for auditory stimuli systematically varying F0 scaling and timing properties; the participants then completed the AQ questionnaire. In the results, the acoustic parameters reporting reduced phonetic differences across accent contrasts for younger Kyungsang generation played a reliable role in perceiving the HH word from HL, suggesting the discrepancy between the perception and the production in the context of sound change. This study also observed that individuals' perceptual variations were negatively correlated with their AQ sub scores. The present findings suggested that the sound change might appear differently between production and perception with a different time course, and deviant percepts could be explained by individuals' cognitive measure.

The purpose of this study was to examine the relationship between preschoolers’ self-perception, peer competence and giftedness. The subjects in this study were 101 preschoolers between the ages of 4 and 5 who attended childcare centers and private kindergartens in Pohang city area. The major findings of this study were as follows: Firstly, there were significant negative correlation between cognitive ability variables of self-perception and aggressive and asocial variables of peer competence. Secondly, there were significant positive correlation between cognitive ability variables of self-perception and humor variables of giftedness. Furthermore there were significant positive correlation between mother acceptance variables of selfperception and logical thinking, task commitment and humor variables of giftedness. Finally, there were significant negative correlation between hyper-distractible variables of peer competence and independence variables of giftedness.

This survey was performed to evaluate and compare cognitive function, self-esteem and depression in the elderly related to aging. The data were collected from 200 elders in eight homes for the elderly in Taegu. Data collection was done from June 1 to 31, 1996. The scale used to measure cognitive function was the MMSE-K(Mini-Mental State Examination-Korea), Self-esteem was measmed using Rosenberg's self-esteem scale and depression using SDS(Self-rating Depression Scale). A comparison of cognitive function, self-esteem and depression by aging were summarised as follows : 1. There were significant differences on the cognitive function score in the elderly according to age group(F=24.81, P<.01). 2. There were significant differences on the self-esteem score in the elderly according to age group(F=3.84, P<.5). 3. There were significant differences on the depression score in the elderly according to age group (F=5.90, P<.1). 4. The general characteristics which affected the cognitive function scores of the elders were sex (F=8.45, P<.5), educational level(F=8.86, P<.5), spousing(F=34.59. P<.01), and the perception of health(F=4.63, P<.5). 5. The general characteristic which affected the self-esteem scores of the elders was the perception of health(F=3.81. P<.5). 6. The general characteristic which affected the depression scores was the educational level(F=3.96, P<.5).

This study was to develope a structural model for risk perception and individual response against terrorism, including several psychological factors - cognitive, social and emotional factors. In this model we measured perceived probability of terrorism, perceived seriousness of the aftermath, and perceived coping(cognitive factors), trust in authorities, in expert group and in preparedness of institutions(social factors), fear and worry(emotional factors), individual preparedness, information seeking, information analysis, and checking relational network(individual behavior responses). Major finding was that cognitive and social factors influenced on emotional factors and then emotional factors influenced on the individual responses. The perceived coping, which one of cognitive factors was linked with individual responses directly and indirectly via emotion factors. We discussed the importance of perceived coping in preparing for terrorism.
