창의성과 지능, 뇌 기능 분화의 관계와 수학 창의성과 지능과의 관계에 대해서는 많은 연구가 이루어지고 있으나 뇌 기능 분화와 수학 창의성, 수학 창의적 문제 해결력과의 관계를 규명은 미흡한 상태이고, Balka(1974)의 연구에서는 수학 창의성과 일반 창의성은 관계가 없다는 연구결과가 있다. 이러한 사실을 바탕으로 생각할 때 뇌 기능 분화와 창의성간의 상관관계의 연구에서 얻어진 결과가 수학 창의성과 관계가 있는지 살펴볼 필요가 있다. 본 연구에서 남녀에 따른 뇌기능 분화의 차이와 좌뇌, 우뇌와 전뇌의 수행 수준이 수학 창의적 문제해결력과는 어떠한 관계가 있는지 알아보기 위해 대구광역시 내에 있는 초등학교 5학년의 40명을 대상으로 뇌 기능 분화 검사, 창의성 검사를 실시하여 서로의 관계를 분석했다. 연구 결과 뇌의 기능 분화 발달은 좌뇌는 남자가 우뇌는 여자가 높았으나 통계적으로 의미가 없었고, 전뇌 집단이 수학 창의적 문제해결력이 가장 높았으므로 전뇌를 고루 발달시킬 수 있는 교수전략에 관한 연구들이 계속 되어져야 할 것이다.

This paper planned to review positively the influence of leading variables - Functional benefits, Emotional benefits, Self-expressive benefits over Consumer-brand relationship, and the structural relationship between Consumer-brand relationship and Brand attachment, Word-of-mouse. For it, we verified our hypothesis utilizing Hierarchial chi-square analysis that was available to statistically verify the size between 2 paths out of Structural models As the result of research, Emotional benefits was more influential than Functional benefits in the formation of Consumer-brand relationship. Additionally, the influential difference between Emotional benefits and Self-expressive benefits was not found in the formation of Consumer-brand relationship. In other words, both Emotional benefits and Functional benefits were proved to have a positive influence on forming Consumer-brand relationship. On the other hand, Self expressive benefits played a more influential role than Functional benefit in the formation of Consumer-brand relationship. The fact was also proved that the higher the formation level of Consumer -brand relationship was, the greater positive influence over Brand attachment and Word-of-mouse Through the above results, it is more desirable to establish brand strategy for forming Consumer-brand relationship through Emotional benefits and Self expressive benefits rather than Functional benefits. Additionally, the Consumer-brand relationship formed by Value benefit is expected not only to get the level of attachment, showing like love, toward the brand deeper, but also to achieve the effect of positive, long term communication through voluntary Word-of-mouse.

The purpose of this study was to investigate the correlation amongst the social function, communication function, activities of daily living and gross motor function beyond existing research on physical function and functional capacity in cerebral palsy. 43 children with cerebral palsy participated in this study and significant correlations were found among social function, communication function, activities of daily living and gross motor function. The greatest significant correlations were found between social function and activities of daily living. Significant higher correlations were found between items of social function and communication, but were lower between social function and gross motor function. The results showed that we consider the social aspects of function of children with cerebral palsy in the area of rehabilitation in order to focus on the problem in real life.

Taking 195 Korean businesses and sorting them out according to the unit types, this study looks into how flexibility strategy in labor market, which consists of numerical flexibility and functional flexibility, takes effect on the organization's outcome variable, which in turn consists of productivity, labor-management cooperation, and job security. In addition, the present study analyzes the role of labor union's moderating effect on the relationship among labor market flexibility, labor-management cooperation, and job security. It is found out as a result that numerical flexibility has no meaningful relation with productivity, labor-management cooperation, and job security, while functional flexibility has a considerably positive relation with them. This result confirms the importance of functional flexibility of business strategy in labor market. The West has continuously insisted the importance of functional flexibility, pointing out problems of numerical flexibility. On the other hand, considering that this study has confirmed functional flexibility's meaningful relation, while it has not found out numerical flexibility's negative relation, it is necessary to study further on the relationship between these two kinds of flexibility. The result of analysis on the role of union power's moderating effect confirms only the union power's interaction effect in the relation between numerical flexibility and labor-management cooperation. The possibility of union's opportunistic behavior can be detected in this result.

The purpose of this study was to examine the mediating effect of functional and dysfunctional expressions of anger on the relationship between covert narcissism and dating violence among college students. The study also investigated gender differences with regard to covert narcissism, dating violence, and functional and dysfunctional expressions of anger. To this end, 339 college students (133 males, 206 females) with heterosexual dating experiences in the Busan Metropolitan area were recruited. They responded to the Covert Narcissism Scale, the Revised Conflict Tactics Scale 2, and the Korean adaptation of the State-Trait Anger Expression Inventory. The results were as follows. First, covert narcissism, dating violence, and functional and dysfunctional expressions of anger differed significantly by gender. Second, there were statistically significant correlations between covert narcissism, dating violence, and functional and dysfunctional expressions of anger. Third, multiple regression analysis showed that dysfunctional expressions of anger for males were positively correlated with dating violence while functional expressions of anger were negatively correlated. For females, dysfunctional expressions of anger were positively correlated with dating violence while functional expressions of anger were not significantly correlated. Fourth, dysfunctional expressions of anger completely mediated the relationship between covert narcissism and dating violence for both males and females, but functional expressions of anger had no mediating effect. These results suggest that dysfunctional anger expression control program should be developed for students which may help those with covert narcissistic tendencies to functionally express their anger. Future research should analyze dating violence prevention and counseling programs.

본 연구는 1982년부터 1996년까지의 유로달러선물과 T-bill 선물의 일별 시계열 자료를 이용하여 단기금리선물의 가격발견기능을 실증적으로 검정하고 있다. 분석방법은 시계열의 불안정성 여부를 알아보는 단위근검정, 장기균형관계를 알아보는 Johansen 공적분검정, 공적분관계가 있는 시장에 대해 설정오류의 문제를 피하고 변수들간의 인과관계를 파악하기 위해 Granger 인과관계모형을 사용하였다. 주요한 결과로 각 금리시계열들은 일차누적 시계열 I(1)임이 확인되었고 공적분관계를 분석한 결과, 각 금리 시계열의 선형결합은 안정적인 장기균형관계가 있음을 나타내 주고 있다. 따라서 각 시장은 서로 밀접한 인과관계가 있음을 암시하고 있다. 또한 선물금리와 현물금리를 대상으로 인과관계검정 결과 유로달러시장의 경우 전기에서는 피드백효과가 있고 후기에는 선물금리의 가격발견기능이 나타났다. T-bill 시장의 경우는 전기에 현물금리가 선물금리에 대해 선행하였고 후기에는 피드백효과가 나타났다. 이렇게 유로달러선물이 후기에서 가격발견기능이 있는 것은 정보통신의 발달과 유로시장의 적은 규제 등으로 유로달러선물시장이 1980년대 후반부터 급성장한 것이 그 원인으로 분석된다.

Objective : This study aimed to examine the association between the structural and functional aspects of social networks and health-promoting behaviors in community-dwelling older adults. Methods : Social networks based on structural and functional aspects and health-promoting behaviors by lifestyle were measured in 226 community-dwelling adults aged 65 years and over. To analyze the collected data, an independent t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical regression were performed. Results : The network size was the highest in the friend network, and the frequency of contact and social support was the highest in the non-living family network. Health-promoting behaviors were highest for activities of daily living and lowest for productive and social activities. All subfactors of social networks showed significant positive correlations with health-promoting behaviors. Hierarchical regression showed social support from neighbors as the variable with a significant effect on health-promoting behaviors; gender and depression were also influencing factors, and this model showed 37% explanatory power. Conclusion : To promote healthy behaviors of older adultsin the community, the development of health promotion programs and related policies considering social networks centering on social support from neighbors is required.

Objective : The typical decline in function due to aging includes limitations in vision, hearing, cognitive function, and activities of daily living. Therefore, this study evaluated the mediating effect of cognitive function on the relationship between vision and hearing and activities of daily living. Methods : The participants in this study were 36,767 persons from the long-term care database on older adults provided by the National Health Insurance Sharing Service. The extracted variables were: (i) independent variables: visual and hearing; (ii) dependent variables: basic and instrumental daily living activities; and (iii) mediator variables: cognitive function. Regression analysis was performed evaluate the mediating effects of the extracted variables. Results : Cognitive function showed a mediating effect of 30% on the relationship between vision and basic daily life activities and 42% in the relationship with instrumental daily life activities. The mediating effect was 50% in the relationship between hearing and basic activities of daily living, and 53% in the relationship with instrumental activities of daily living. Conclusion : Prevention programs for functional decline due to aging are in progress in Korea. Based on the results of this study, establishing a prevention program would help promote successful aging.
