This paper presents a TS (Takagi-Sugeno) type FLC (Fuzzy Logic Controller) with only 3 rules. The choice of parameters of FLC is very difficult job on design FLC controller. Therefore, the choice of appropriate linguistic variable is an important part of the design of fuzzy controller. However, since fuzzy controller is nonlinear, it is difficult to analyze mathematically the affection of the linguistic variable. So this choice is depend on the expert's experience and trial and error method. In the design of the system, we use a variety of response characteristics like stability, rising time, overshoot, settling time, steady-state error. In particular, it is important for a stable system design to predict the steady-state error because the system's steady-state response of the system is related to the overall quality. In this paper, we propose the method to choose the consequence linear equation's parameter of T-S type FLC in the view of steady-state error. The parameters of consequence linear equations of FLC are tuned according to the system error that is the input of FLC. The full equation of T-S type FLC is presented and using this equation, the relation between output and parameters can represented. As well as the FLC parameters of consequence linear equations affect the stability of the system, it also affects the steady-state error. In this study, The system according to the parameter of consequence linear equations of FLC predict the steady-state error and the method to remove the system's steady-state error is proposed using the prediction error value. The simulation is carried out to determine the usefulness of the proposed method.

This study is about choice attribution of customers make in food and beverage events. The researcher provided practical plans to uplift food-related enterprises and activate management through surveys and positive analyses, targeting customers who use food services. First of all, all event plans must include customer demands, social changes, special qualities of the business, and market research. Second, low demand season must be customers will be induced to the events. Third, prediction for market variable and solutions must be thoroughly examined and plans should look into the future to maintain a long period of time. Fourth, sufficient communication between planners and employees should be made before the event starts, so that food and beverage businesses can gain trust and quality of event services.Fifth, immaterial service and visible goods/menus in business of food and beverage events must be closely matched. Sixth, menus introducing a variety of merchandise, quality of nutrition and health of the business should be developed. Also, events from countries(regions) should be hold to create a market of cultural exchange. Seventh, for hereafter event plans, feedbacks are needed concerning customers needs and demands through customer care, after the food and beverage events. Eight, faculty management for convenience, kindness, safety, and life preserver accommodations in parking areas must be made, as automobiles are necessaries for people in Mycar era. The ninth, off-line and on-line care through on-line business construction and production of homepage must be done, due to the fact that even the well-made events are bound to fail if they are not delivered to the customers.

This study aimed to analyze access mode choice behavior for KTX Passengers. To fulfill the aims of this study, Dong-Daegu Station was selected as a station for a case study. This study takes place in two stages. These are (i) descriptive statistical analysis of transportation status before and after introduction of the KTX, (ii) empirical model estimation for analyzing access mode choice behavior. This study makes use of the data from travel survey from Daegu metropolitan area. The main part of the survey was carried out in the KTX Dong-Daegu station. The data was collected from a sample of 1,800 individuals. The survey data includes the information on travel from Dong-Daegu station to Seoul. From descriptive statistical analysis of transportation status before and after introduction of the KTX, it is found that revealed demand of the KTX is lower than that expected. Moreover, it is found that the low demand of the KTX stems from high cost for the KTX itself and inconvenience( including travel time and cost) of access mode. In order to analyze mode choice behavior for accessing Dong-Daegu station, multinomial logit model structure is used. For the model specification, a variety of behavioral assumptions about the factors which affect the access mode choice, were considered. From the empirical model estimation, it si found that access travel time and access travel cost are significant in choosing access mode. Given the empirical evidence, we see that improvement of access transportation system for Dong-Daegu station is very important for enhancing the use of KTX.

The purpose of this research is to valuate the economic value of the arboretum which will be provided in Multifunctional Administrative City by estimating citizens' willingness to pay with double-bounded dichotomous choice contingent valuation method, and to provide the basic information necessary for designing and managing it for the future by identifying the types of the variables affecting the WTP. It was found that respondent's average WTP for arboretum was \23,508, and when this figures applied to all the Seoul citizens aged between 20 and 59, the economic value of it was \157,000,000,000. The variables affecting the amount of WTP were visit intention, variety seeking tendency, level of income and environmental attitude. However, environmental attitude negatively affected the amount of WTP. Average WTP for the entrance fee was \5,090, and both variety seeking tendency and visit intention were influencing factor affecting the amount of WTP. Respondents were taking charging entrance fee for granted because most of arboretums are commercial. It can be expected that much of maintenance cost will be covered from the entrance fee.

Atopic allergy implies a familial tendency to manifest alone or in combination such as asthma, rhinitis, urticaria and atopic dermatitis. The patient with atopic dermatitis shows a variety of humoral and cell-mediated immune dysfunction, including an elevation of serum IgE level, multiple positive immediate skin tests to a variety of antigen. A 30 year old female patient suffering from an atopic dermatitis on face, has been administered a stellate ganglion block(SGB) with a 1% mepivacaine 5cc. She complained of bronchial hyperresponsivness such as cough, soreness, and inspiration difficulty for 5 days following the treatment, so we have reduced 1% mepivacaine dose from 5cc to 3cc. She had no complain of bronchial hyperresponsivenss and the lesion of atopic dermatitis was improved. From our result we conclude that SGB appears to be a good choice for the treatment of the atopic dermatitis and only 1% mepivacaine 3cc is possible in complete SGB.

In this experiment, we have manufactured thermal-curable silver pastes for direct printing. And to enhance conductivity, printability, adhesion and hardness during polymer direct-gravure prints, we have manufactured Ag pastes by adding variety of filter contents. Then we have investigated characteristics of rheology in paste according to the gravure printability and the properties of printed conductive patterns. Depending on a variety of Ag powder, there was a big difference in sharpness of printed pattern. And also by the use of carbon, there was a big difference in amount of solvent used, conductivity and in hardness. We could improve doctoring and the sharpness of a pattern by adding Ag paste in carbon particle, but as we have used nano-sized particle, there was an increase in the amount of solvent used and also we have found out that it gives a bad effect as adhesive and hardness becomes weaker. Even though Ag particle has the same spherical shape, the surface treatments could differ from one another. And by the appropriate choice and with the suitable combination of Ag powder, excellent printability and conductivity could be obtained.

Although previous studies have emphasized factors affecting people's variety-seeking behavior, research has not been performed to examine the interaction effect of good-bad luck and embodied cognition (hand washing) on variety-seeking behavior. Experience of good and bad luck affects consumer information processing and hand washing is known to reverse the experience of luck. Understanding the interaction effect of good/bad luck and hand washing on variety seeking behavior will shed important light on consumer behavior including choice and product purchase. To do this, a study was performed to investigate the effects of good/bad luck priming and hand washing on variety seeking behavior. Participants were primed with good or bad luck and then were asked to either wash their hands or not. After that, they were led to choose yogurt for the next seven days and the dependent measure was the number of different tastes of yogurt participants picked up. An interaction effect of luck priming and hand washing was found. Results indicate that, in good luck condition, there was no difference in variety seeking behavior between hand washing participants and non-hand washing participants. However, in bad luck condition, hand washing participants chose less diverse tastes of yogurt than non-hand washing participants. Implications of the study findings for the field of consumer psychology and marketing are discussed.
