Recently, theoretical interests in automatic uses, which can be activated without conscious intention, have been increased. According to previous studies, automatic uses are known to be determined by the strength of habit, the frequency of past uses, and emotional experiences such as cognitive absorption. Concerned on the influences of the above three factors on automatic uses, this paper suggested the following research questions: 'Which effect of cognitive absorption on automatic considering habit?' and 'Does the frequency of past uses always influence habit?'. In order to answer the research questions, this study suggested a research model which would explain the relationship among cognitive absorption, habit, and uses. Especially, cognitive absorption is formed as a moderating variable of the relationship between past use and habit, and the relationships among variables are longitudinally expanded. The suggested research model was empirically tested by surveying 175 'Facebook' users and analysed by partial least square (PLS), which showed the suggested hypotheses are significant. This results answered the research questions as followed: First, cognitive absorption moderates the relationship between habit and automatic use. Second, the frequency of past uses would not always influence the formulation of habit rather but may be influenced by habit.

This study was performed to explore multidimensional customer royalties and relating factors. 900 households, $1\%$ sample were randomly selected from K city located in Kangwon province. Interview survey was performed with structured Questionnaire for the entire people, 923 persons who experienced medical service utilization during one year before survey on time, september, 2004. In comparison of customer royalties by sociodemographic characteristics, the older group showed the higher level of cognitive and attitudinal royalties significantly. Education and income level also, showed negative relationship with cognitive, attitudinal and behavioral loyalties significantly. The more being a female and a visitor at oriental medicine clinic, the higher level of attitudinal loyalties. Customer satisfaction was a critical explaining variable for cognitive, attitudinal and behavioral loyalties. In multiple regression analysis, some sociodemographic characteristics showed significant relation with customer loyalties and customer satisfaction was the strongest relating variable to customer loyalties. In conclusion, multidimensional approach for customer loyalty is useful for understanding customer behaviors comprehensively. Future studies should focus on developing the more specific and valid measurement tools for customer loyalty in medical service.

In recent years, most companies are making strategic strides to respond to changes in the competitive landscape. This trend is proceeding independently from industry to industry, and the Chinese cosmetics industry, which is at its peak, is no exception. In the meantime, the question of whether the concept of strategy group and related theories are suitable for advanced markets and whether they are applicable to emerging markets such as China is an interesting subject of inquiry. The purpose of this study is to classify strategic groups based on the cognitive approach of CEO's in the Chinese cosmetics industry. Some of the existing studies on strategic groups have raised limitations on the theoretical validity of the classification and criteria of strategic groups. However, since the concept of the strategic group becomes a middle level analysis unit between the enterprise and the industry, applying this concept to the Chinese cosmetic industry will help identify the strategic group existing in the industry and grasp the composition of the entire industry.

Managerial intuition is a well-recognized cognitive ability but still poorly understood for the purpose of developing effective decision support systems. this research investigates whether the differences in accuracy of "time series forecasting" are related to the differences in one's cognitive style, using statistical test The hypotheses established in the research model did not have positive correlation The lack of correlation between "cognitive style and physiological measures" and accuracy in forecasting may be caused by uncontrolled external variable. Thus, further analyses on physiological characteristics and brainwaves are needed. The approaches such as neural network and data mining are proposed.

Vascular dementia is a very frequent form of dementia. Debates over classification and diagnostic criteria, and controversy over identifiable treatment targets will continue until distinct pathophysiological mechanism of vascular dementia is found. Clinical diagnostic criteria are sufficiently strong to be useful for clinical trials, but need further refinement. Cognitive changes in vascular dementia are more variable than other disorders, and are dependent on the vascular pathology. Accurate diagnosis of vascular dementia is known to need the presence of reliable cerebrovascular disease on brain imaging. Although it seems obvious that cerebrovascular disease causes pathological damage and impaired cognition, it is very difficult to find the accurate contribution of cerebrovascular pathology to cognitive decline. Most studies have shown a small but significant benefit of cholinesterase inhibitors on cognition, the significance of this effect has been slight and benefits on global functioning, activities of daily living, and behaviour have not been consistently reported. Management of vascular dementia should focus on identifying and managing vascular risk factors.

Cognitive radio is a paradigm for wireless communication in which either network of wireless node itself changes particular transmission or reception parameters to execute its tasks efficiently without interfering with the licensed users. This paper represents a performance of the cognitive radio technology on dual polarized MIMO system using six-port receiver. Six-port technology is well known direct conversion receiver. In this paper, a six-port phase discriminator based polarization signal separation is shown. That is, the SER(Symbol Error Rate) performance is improved using polarization separator and simple receiver architecture is proposed applying six-port receiver. The six-port technology has priority to adapt changeable frequency system and variable environments for cognitive radio. In general, dual polarized MIMO system has good capacity and quality using polarization separator [1].

Digital knowledge and information goods as experience goods have some unique characteristics such as close to zero reproduction and distribution cost, high price volatility, and low price acceptability. For the reasons, the pricing policies of digital knowledge goods are very difficult and complicate. Also, most consumers of digital goods have experienced cognitive dissonance after buying decision. The purpose of this paper is to investigate what factors affect the price acceptability level and cognitive dissonance of digital knowledge goods buyers. This paper suggest a structural model that was established by the cognitive dissonance theory and S-O-R(Stimulus-Organization-Response) model. The model is consisted of four exogenous variables and three endogenous variables. The empirical test and statistical analysis suggest following results and practical implications. The variables such as product involvement and perception of price fairness that have positive roles to price acceptability have strong influence on the all the three endogenous variables. But the variables such as sale proneness and price mavenism that have negative roles to price acceptability have little influence on the all the three endogenous variables. In the model, the payment intention was very important mediating variable between exogenous variables and two dependent variables, ie. price acceptability and cognitive dissonance. These results imply that the digital knowledge portals must have some differentiated pricing policies to the customers who have price consciousness and price mavenism. Also, they need some special promotions to whom have positive attitude to the value of digital goods.

PURPOSE: The progression of the center of pressure (COP) velocity of the stance phase may have important roles for predicting gait speed in older adults with cognitive decline. This study was conducted to identify the correlation between gait speed and the velocity of COP progression during the stance phase in older adults with cognitive decline. METHODS: Forty adults aged 65 years or older (twenty participants without cognitive decline, 20 participants with cognitive decline) were recruited. The COP progression velocity was measured using an F-scan pressure-sensitive insole system. The stance phase was divided into four sub-stages. (loading response, mid-stance, terminal stance, and pre-swing). Gait speed, double support phase, and cadence were also measured. Correlations and multiple regression analyses were performed. RESULTS: Gait speed was associated with the COP progression velocity in midstance (r = .719, p < .05), cadence (r = .719, p < .05) and the COP progression velocity in loading response velocity (r = .515, p < .05) in older adults with cognitive decline. However, no correlation was found in older adults without cognitive decline. In multiple regression analysis using gait speed as a dependent variable, the COP progression velocity in midstance and cadence were significant predictors of gait speed, with the COP progression velocity being the most significant predictor. CONCLUSION: The COP progression velocity is an important factor for predicting gait speed in older adults with cognitive decline, suggesting that the cognitive function influences gait speed and the velocity of COP progression.

This study examined gender differences of the effect of playfulness on the social skills of young children. The subjects were 242 4- to 6-year-old children at five nursery schools and kindergartens. Results showed that playfulness influenced social skills of young children. In particular, young children's playfulness was a more effective variable of assertion than self-control, cooperation and responsibility. Cognitive spontaneity and social spontaneity were the most effective variable of social skills. Playfulness had variable influences on social skills by gender: Among boys, playfulness was a less effective variable of cooperation than the other variables of social skills. Among girls, playfulness was a less effective variable of self-control than other variables of social skills.
