This study focuses on the finding out the structural effect of consumers' cognitive age affecting consumer innovativeness due to the mediating effect of perceived easy of use of mobile and perceived usefulness of mobile. For this study, a self report survey is conducted through a structured questionnaire, and a parallel double-mediated effect analysis is performed using the process macro of SPSS for the analysis. In the study results, it is found that the cognitive age of consumers directly have a statistically significant negative effect on consumer innovativeness. In addition, in the analysis to verify the mediating effect of perceived easy of use of mobile and perceived usefulness of mobile, it is shown that perceived usefulness of mobile has a positive and significant effect on consumer innovativeness. Through this, The contribution of this study can be attributed to the fact that it analyzed the structural relationship between the perceived ease of use of mobile and the perceived usefulness of mobile in the process of consumers' cognitive age affecting consumer innovativeness.

This study, through the potential research variables constituting smartphine shopping utilization, affects to some extent the social relevance and rapid adaptability of technology according to the cognitive age level perceived by customers. Research hypotheses and research models were established and tested to verify the research results on how they affect brand loyalty within the segmented market to which they belong. The purpose of this study is as follows. First, it was verified through the degree of casual relationship between smartphone shopping usage and potential research variables of innovation, convenience, usefulness, and hedonism that compose it, on the cognitive age level. Second, according to the cognitive age level perceived by customers themselves, it was verified through the degree of casual relationship between the mediators of social relevance and technology quick adaptability. Third, the casual relationship between social relevance, technology quick adaptability, and brand loyalty was verified according to the cognitive age level. Fourth, a theoretical study was conducted on the conceptual and operational definitions of the research variables of the research model of this study.

Objectives : Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects. Methods : To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis. Results : Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R²=0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter. Conclusions : In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.

This paper attempts to highlight such issues as the personal psychological problems due to the aging, and tries to investigate the effectiveness and the potentials of bibliotherapy to heal the wounded hearts of people who suffer from aging. Portrayed through a qualitative surveys and interviews with five subjects selected by the researchers, discussions were elaborated around three factors such as physical, cognitive. and social factors. The participants. throughout the study, came to understand and to narrate their own problems objectively and to discern their wounds. It was also observed that they felt relieved and stable after reading the books presented by the researchers. As a result, physical decline. isolation from family members, solitude in society and decline of self-esteem they have experienced since their mid-40s were recognized as natural changes from aging which were to overcome.

치매라는 말은 Dement라는 라틴어에서 유래된 것으로써 '정상적인 마음과는 거리가 멀어진것', '정신이 없어진 것'이라는 의미를 지니고 있다. 치매는 나이가 들어감에 따라 정상적으로 발달한 뇌가 후천적인 외상이나 질병 등 외부적인 요인에 의해 손상되거나 파괴되어 언어ㆍ학습ㆍ지능 등에 대한 전반적인 인지기능과 고등정신기능이 비정상적으로 감퇴되는 복합적인 임상증후군을 포괄적으로 이르는 것을 말한다.

외상후 뇌손상은 대표적이며, 가장 중요한 신경정신계 질환의 하나이다. 더욱이 외상후 뇌손상 환자들은 각종의 사고 및 산업재해 등으로 인해 그 수가 급증하고 있으며, 특히 인지기능의 장애로 인한 다양한 기질성 정신장애로 고통을 겪게 된다. 따라서 외상후 뇌손상은 손상의 시점에서부터 정확하고 올바른 평가는 물론 손상후의 경과 및 치료대책의 수립에 있어서 체계적이며 종합적인 신경인지기능의 평가는 필수적이다. 왜냐하면 신경인지기능평가는 뇌의 손상부위와 이와 관련된 기능장애 및 행동의 변화에 대한 객관적인 자료를 제시해 주기 때문이다. 신경인지기능 평가의 영역은 지각, 운동기능은 물론 주요인지기능인 기억, 언어, 실행 및 감정조절능력에 이르기까지 다양하며, 외상후 뇌손상환자들은 손상부위 및 정도에 따라 신경인지기능의 장애를 초래하게 된다. 대표적인 신경인지기능평가 도구로는 KWIS, Halstead-Reitan, Luria-Nebraska batteries, 특히 전두엽기능검사인 Wisconsin Card Sorting Test (WCST)를 비롯하여, 현재는 PC/S Vienna Test System 및 Stim등의 각종 전산화 인지기능검사가 개발되어 임상에서 활발히 사용되고 있다. 즉 외상후 뇌손상환자를 위한 신경인지기능평가의 목적은 뇌손상과 관련된 신경인지기능장애를 정확히 평가하여, 환자 개개인에 적합한 인지재활치료 계획을 수립하는데 있다. 물론 여기에는 신경정신상태검사(neuropsychiatric mental status examination)를 통하여 외상 후 뇌손상의 경과 및 예후에 결정적인 영향을 미칠 수 있는 나이, 의식소실 및 외상후 기억 손상 시간의 정확한 측정은 물론 심리 사회 문화적인 상태와 두부외상전 환자의 지적수준 및 사회 적용기능이 함께 평가되어야 할 것이다.

모든 생명체는 나이를 먹으면서 노화해간다. 이러한 노화를 방지해 보려는 인간의 꿈은 노화의 본질이 무엇인지와 노화는 왜 일어나는지에 대한 의문 등을 끊임없이 제기하고 있다. 이런 노력들은 단순히 수명을 연장하기 위해서라기 보다는 살아있는 동안만이라도 젊음을 유지하고자 하는 욕망에서 비롯한 것일 것이다. 노화의 과장은 우리몸의 눈, 뇌, 심장등 구성기관 모두에서 나이를 먹으면서 일어나고 있다. 피부도 마찬가지여서 나이에 따라 어쩔 수 없이 노화해 간다. 즉 각질형성세포, 멜라닌세포, 땀샘들의 기능이 점차 떨어져 간다. 어린이들의 터질듯한 팽창력과 유연성을 가진 피부가 어느덧 청소년기의 매끄럽고 윤기가 흐르던 시절을 지나 성년기에 이르면 거칠고 메마른 상태가 되며, 그 후 주름이 지고 탄력성이 소실되는 노화 피부상태에 도달하게 된다. 피부, 눈, 신경 등 생체 노화과정의 생리적 규명이 현재 의학의 한 첨단분야로 등장하고 있으며, 피부노화에 대해서도 많은 연구가 진행중이다.

아이들은 항상 안전사고에 노출되어 있다. 특히 걷거나 뛰기 시작하는 나이에는 위험에 대한 인지 능력이 부족하기 때문에 생각지도 못한 곳에서 다치기 쉽다. 이때 놀란 부모가 허둥대다가 제대로 대처하지 못하거나 잘못된 의학상식만을 믿고 자의적인 처치를 해 상처가 덧나게 할 수도 있다. 일상생활에서 알아두면 유용한 아동 응급처치 요령을 상황별에 맞춰 알아보도록 하자.

Objectives：The study was performed to compare the executive function(EF；Inhibition, Planning and Working memory) between ADHD and normal group, and to controll the effect of age and intelligence. And the function of inhibition was assessed in two dimensions(cognitive inhibition and motor inhibition). Methods：K-WISC III and EF test(Go-No-Go, Stroop test, Tower of Hanoi, Digit) was administered to both 25 children with ADHD and 25 normal control participants, all aged between 7 and 12. The results were analyzed after statistically controlled for age and intelligence. Results：Children in the ADHD group had significantly lower IQ score than those in the control group and consistent relations were found between the child's age and the study's major variables. Once IQ and age were controlled, results indicated that children with ADHD had deficit only cognitive inhibition and motor inhibition. There was no significant difference in planning and working memory. Conclusion：These results suggested that specific deficits in inhibition control rather than general EF deficits are associated with ADHD. So inhibition is the core problem of children with ADHD. Thus, the therapeutic approach focused on cognitive inhibition and motor inhibition is required.
