This study attempts to reveal that the connection between consumers' self enhancement and consumer-brand relationship can be formed from brand experiences not only through a direct use of products or brands but also through companies' marketing activities including advertising or promotion, in that consumers' sensual, affective, cognitive, and behavioral response to brands are included in brand experiences. After experiencing the Samsung Galaxy S brand with manipulated stimulus, 248 respondents' positive emotion and self-enhancement were increased. Also the positive emotion induced by brand experience increase self-enhancement. This study also shows that brand experience and self-enhancement can significantly affect consumer-brand relationship which in turn affects brand loyalty such as satisfaction, recommendation intention, and repurchase intention. Experiencing strong, favorable, and attractive brand personalities may help consumers to increase positive emotions with self-enhancement and help companies to have brand loyalty through consumer-brand relationship.

The effects of purple sweet potato anthocyanin (SPA) and Cordyceps mushroom extract (CME) on lipid peroxidation, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and cognitive deficits were examined. Both SPA and CME exhibited DPPH radical scavenging activities with similar potency. In contrast, only SPA was shown to effectively inhibit lipid peroxidation initiated by $Fe^{2+}$ and ascorbic acid in rat brain homogenates. Furthermore, SPA markedly enhanced cognitive performance, assessed by passive avoidance test in ethanol-treated mice. Combined treatments with SPA and CME did not significantly influence the effects of SPA alone. These results demonstrate that anthocyanin prepared from purple sweet potato exhibits memory enhancing effects, which may be associated with its antioxidant properties.

본 논문에서는 파킨슨병이 우리 사회에서 증가하고 있고 노인들 만이 아니라 젊은 사람들에게도 나타날 수 있기 때문에 환자들을 위해 근 기능 및 인지능력을 향상 시키는게 목표이다. 파킨슨병은 현재까지 원인이 알려지지 않았지만 도파민 세포가 손상되는 것으로 알려져 있기 때문에 아직은 약물치료와 식이요법 치료를 통해 질환의 증상을 중지시키거나 느리게 할 수 없다. 파킨슨병의 증강 중 가장 중심이 되는 근 기능 문제와 인지능력을 동시에 향상 시킬 수 있는 기대를 할 수 있으며 이것을 통해 다른 증상들도 느려 질 수 있도록 하는 기대를 할 수 있다. 프로그램을 통한 근 기능 능력이나 인지능력을 동시에 향상하고 대상자 개개인의 능력에 맞게 운동을 할 수 있는 프로그램을 개발하는데 목적이 있는 연구이다.

Finding a way to strengthen human cognitive functions, such as learning and memory, has been of great concern since the moment people realized that these functions can be affected and even altered by certain chemicals. Since then, plenty of endeavors have been made to look for safe ways of improving cognitive performances without adverse side-effects. Unfortunately, most of these efforts have turned out to be unsuccessful until now. In this study, we examine the effect of a natural compound, idesolide, on hippocampus-dependent recognition memory. We demonstrate that idesolide is effective in the enhancement of recognition memory, as measured by a novel object recognition task. Thus, idesolide might serve as a novel therapeutic medication for the treatment of memoryrelated brain anomalies such as mild cognitive impairment(MCI) and Alzheimer's disease.

Several studies have focused on multimedia transmission over wireless sensor networks (WSNs). In this paper, we propose a comprehensive and robust model to transmit images over cognitive radio WSNs (CRWSNs). We estimate the spectrum sensing frequency and evaluate its impact on the peak signal-to-noise ratio (PSNR). To enhance the PSNR, we attempt to maximize the number of pixels delivered to the receiver. To increase the probability of successful image transmission within the maximum allowed time, we minimize the average number of packets remaining in the send buffer. We use both single- and multi-channel transmissions by focusing on critical transmission events, namely hand-off (HO), No-HO, and timeout events. We deploy our advanced updating method, the dynamic parameter updating procedure, to guarantee the dynamic adaptation of model parameters to the events. In addition, we introduce our ranking method, named minimum remaining packet best channel selection, to enable us to rank and select the best channel to improve the system performance. Finally, we show the capability of our proposed image scrambling and filtering approach to achieve noticeable PSNR improvement.

The purpose of this study is to predict the usefulness and predictable effects of the use of dementia prevention games and dementia management applications provided in smart-phones for the elderly. First, 6 dementia diagnostic tools used to verify the effectiveness of the dementia prevention program were selected and the cognitive domains tested by each diagnostic tool were extracted. Second, 29 smart-phone dementia prevention game applications and dementia management applications were selected and the expected effects after using these applications were analyzed in connection with the cognitive domain extracted from the dementia diagnosis tool. As a result, it was expected that it would be helpful to manage dementia prevention by improving cognitive function in certain areas when playing games or managing dementia continuously using smart-phone dementia prevention applications. Smart-phone dementia prevention applications will be useful in improving the cognitive ability of the elderly and preventing dementia by supplementing the limitations of the dementia prevention program that is operated offline through time-space ease of use, continuous usability and economic feasibility.

Context : Oriental medicine deals with mind cardinally and effectiveness of CBT on weight control is well-known. but there is no well-structured psychotherapy for weight control like CBT in Oriental medicine so far. Therefore It is necessary to develop new cognitive program based on the theory of Oriental medical. Objective: This study examined whether Yangsung program based on new cognitive weight regulation model is effective on weight loss, self esteem and self control. Design and setting: 44 women were assigned randomly to 2 groups; experimental group(n=24) and control group(n=10). experimental group had 11 sessions consisted of cognitive therapy, meditation, general diet and exercise education. Control group had personal interview with general diet and exercise education and ear acupuncture once a week for two months. All subjects were weighed and evaluated with Rosenberg self esteem scale, and three factor eating questionnaires at the beginning of the program and at the end of the program. Result: Experimental group reported significant changes of weight, self esteem, restraint eating, disinhibition and hunger(p<0.01). Compared with control group, more significant(p<0.05) Weight reduction and self-esteem enhancement were reported in experimental group than control group. There is no significant difference between two groups in changes of restraint eating, disinhibition and hunger.

The life review means a process of appraising life of oneself and it is essential for finding the meaning of life in old age. The memoir writing is a kind of method of life review. The memoir writing program used in this study focused especially on enhancing the cognitive skills by providing priming and retrieval support for memory performance in reminiscing past experiences. All fourteen participants were healthy and normal community dwellers and attended four-month long programof memoir writing classes which are consisted of different themes for each week. The aim of this study was to examine if the memoir writing program would render the positive effect on mental health and cognitive ability of the elderly. The results were that quality of life, life satisfaction, ego integrity of the participants showed positive change and the level of depression was significantly reduced compared to that of the control group. The findings in the present study suggest that the memoir writing can serve as one of the community initiative program to the growing population of the elderly for their emotional and cognitive challenges that they face everyday. To warrant the validity of the program, further study is needed for other sectors of elderly population, such as elderly living alone or those with both physical and/or cognitive disadvantages.

Landmarks like high-rise building are one of the important elements for the enhancement of city identity and provides the hierarchy of city streets, playing a central and symbolic role in cities. Research on physical attribute of landmarks, such as height, distance, location and shape, which are suitable for a city scale, can help a city create a distinct image and maintain comprehensible structure. To achieve this purpose, it is necessary to understand the spatial and cognitive characteristics of a landmark for the establishment and management of it. The results of this study can be summarized as follows: 1. The level of representativeness of a landmark increases in proportion to the degree of cognitive intensity on it. The relation between representativeness and cognitive intensity can be explained as the log-function as follows: Log(the number of people who respond "It has representativeness")=$-1.2579+1.5908{\times}$(cognitive intensity); 2. There are a few differences based on the attributes of respondents: while gender has no distinct influence, residential period and age show statistically meaningful influence on cognitive intensity of a vertical landmark Cognitive intensity of an individual landmarks especially, differs according to the class of main users. Because of frequent changes in occupation or employment, respondents consider the distance from a residential area more important than the distance from a working area in evaluating cognitive intensity of landmarks; 3. landmark can be classified into two kinds: a district landmark and an urban landmark A district landmark is closely connected with physical attributes of the landmark itself, such as distance, size and height. An urban landmark is mainly related to cognitive attributes such as the image and identity of a city as a whole. As a result, the landmark analysis data in this research provides spatial order and identity in a city. It is difficult to establish and reinforce the image of a city as a single element ike a landmark. However, withy steady follow-up research, this study could be seen as a systematic and logical model to improve urban landscape and image.
