Purpose: To overcome the question that depends too much on expert's subjective judgment in traditional risk identification, this paper structure the multilevel generalized fuzzy comprehensive evaluation mathematics model of the risk identification of project, to research the risk identification of the project. Research design, data and methodology: This paper constructs the multilevel generalized fuzzy comprehensive evaluation mathematics model. Through iterative algorithm of AHP analysis, make sure the important degree of the sub project in risk analysis, then combine expert's subjective judgment with objective quantitative analysis, and distinguish the risk through identification models. Meanwhile, the concrete method of multilevel generalized fuzzy comprehensive evaluation is probed. Using the index weights to analyse project risks is discussed in detail. Results: The improved fuzzy comprehensive evaluation algorithm is proposed in the paper, at first the method of fuzzy sets core is used to optimize the fuzzy relation matrix. It improves the capability of the algorithm. Then, the method of entropy weight is used to establish weight vectors. This makes the computation process fair and open. And thereby, the uncertainty of the evaluation result brought by the subjectivity can be avoided effectively and the evaluation result becomes more objective and more reasonable. Conclusions: In this paper, we use an improved fuzzy comprehensive evaluation method to evaluate a railroad engineering project risk. It can give a more reliable result for a reference of decision making.

Objectives : Our purpose of this study was to evaluate the association between abdominal adipose tissue and oriental obesity pattern identification. Methods : This study was performed in 78 healthy obese(BMI(body mass index)${\geq}25kg/m^2$) women in Seoul. Subjects underwent abdominal CT(computed tomography) scanning and were asked to complete the oriental obesity pattern identification questionnaire. Subjects were given written consent and this study was performed under permission of institutional review board of Kyung-hee East-west Neo medical center. Results : 1. VFA(visceral fat area) and VSR(visceral/subcutaneous adipose tissue ratio) were significantly correlated with stagnation of the liver qi(肝鬱, gan-yu)(p<0.05). But, other patterns were not significantly correlated with oriental obesity pattern identification(p>0.05). 2. We evaluated a difference of oriental obesity pattern identification score in visceral obesity group(n=34) versus non-visceral obesity group(n=44). Scores of all patterns except food accumulation(食積, shi-ji) were significantly higher in the visceral obesity group than in the non-visceral obesity group(p<0.05). Especially, there was a further significant difference in stagnation of the liver qi(肝鬱, gan-yu)(p<0.01). Conclusions : Generally, the stagnation of the liver qi(肝鬱, gan-yu) has a close relation with stress and depression. This study suggests that stress and depression might be correlated with visceral fat, and the use of oriental obesity pattern identification would be helpful for planning a treatment schedule of visceral obesity in the clinic.

The objectives of this study were to explore rural elderly's perception on rural area as a proper place to live for the elders and to find out their residential satisfaction and its related variables. The data were gathered through the questionnaire survey from 241 rural elderly over 70 aged living in Gyeonggi province during July 2005. The major findings of this study were as follows: 1) Those who are men, having experience living in urban area, and favorable perception to social relation with other residences prefer the rural area to urban area as living place for the elderly ; 2) Those who are subjectively perceived healthy and favorable perception to social relation with other residences tend to be in higher residential satisfaction than other groups ; 3) Such variables as age, educational background, living term in community and urban area were not significant to rural elderly's perception on rural area as a proper place to live for the elders and residential satisfaction; 4) Such variables as identification as community residences, people-oriented personality, sex and having experience living in urban area explained 26.4% of variance in rural elderly's perception on rural area as a proper place to live for the elders ; 5) Such three variables as identification as community residences, relationship with the primary group and age explained 55.2% of variances in residential satisfaction; 6) In shortly, the most influential factor to rural elderly's perception on rural area as a proper place to live for the elder and residential satisfaction was their identification as community residences.

Objectives: Metabolic syndrome is considered a coronary heart disease risk factor and its prevalence rate is increasing in Korea. Because obesity is relevant to metabolic syndrome, we investigated the relationship between metabolic syndrome and the Obesity Pattern Identification Questionnaire in middle-aged health check-up examinees. Methods: This was a cross-sectional study with 125 patients who visited a health promotion center of university hospital from October 2012 to January 2013. We analyzed the association of Obesity Pattern Identification Questionnaire and the diagnostic criteria of metabolic syndrome. Results: Pi deficiency (脾虛), phlegm (痰飮), liver stasis (肝鬱) and food accumulation (食積) pattern showed significantly highs score in the group with hypertriglyceridemia. Also, females demonstrated significantly high scores of liver stasis (肝鬱) and food accumulation (食積) in the group with hypertriglyceridemia. The questions of Pattern Identification that showed especially significant high score in the group of hypertriglyceridemia are as follows: 'Easily get annoyed', 'Usually worried', 'Frequently overeating or bingeing', and 'Having more after getting full'. There are positive correlations between triglyceride and the score of Pi deficiency (脾虛), phlegm (痰飮) and food accumulation (食積) pattern. Conclusions: Obesity Pattern Identification Questionnaire can be used for the management of hypertriglyceridemia in an effort to prevent metabolic syndrome.

The purpose of this study was to identify the causal relationship between the brand, the brand equity and brand equity of a tourist destination. The effect of love mark on self identification is that the relationship between love mark performance and self-identification time is significant, and that of love mark is in the order of self identification. Trust mark of love mark has a significant relationship with self identification. The relationship between brand intimacy and brand quality and the relationship between trust and brand quality were significant in relation to the brand mark, but brand mark was not significant. In addition, in the relationship between brand value and love-mark, there is a significant relationship between performance and brand value, relationship between intimacy and brand value, and performance is not significant in brand value. There was a significant relationship between gender and behavioral intention. The relationship between gender identity and behavioral intention was positively related to brand equity.

The problem of the structural identification becomes important, particularly with relation to the rapid increase of the number of the damaged or deteriorated structures, such as highway bridges, buildings, and industrial facilities. This paper summarizes the recent studies related to those problems by the present authors. The system identfication methods are generally classified as the time domain and the frequency domain methods. As time doamin methods, the sequential algorithms such as the extended Kalman filter and the sequential prediction error method are studied. Several techniques for improving the convergences are incorporated. As frequency domain methods, a new frequency response function estimator is introduced. For damage estimation of existing structures, the modal perturbation and the sensitivity matrix methods are studied. From the example analysis, it has been found that the combined utilization of the measurement data for the static response and the dynamic (modal) properties are very effictive for the damage estimation.

This paper is concerned with a computational method for recovering a crack shape of steam generator tubes of nuclear plants. Problems on the shape identification are discussed arising in the characterization of a structural defect in a conductor using data of eddy current inspection. A surface defect on the generator tube ran be detected as a probe impedance trajectory by scanning a pancake type coil. First, a mathematical model of the inspection process is derived from the Maxwell's equation. Second, the input and output relation is given by the approximate model by virtue of the hybrid use of the finite element and boundary element method. In that model, the crack shape is characterized by the unknown coefficients of the B-spline function which approximates the crack shape geometry. Finally, a parameter estimation technique is proposed for recovering the crack shape using data from the probe coil. The computational experiments were successfully tested with the laboratory data.

Since its birth in 1993, fuzzy time series have seen different classes of models designed and applied, such as fuzzy logic relation and rule-based models. These models have both advantages and disadvantages. The major drawbacks with these two classes of models are the difficulties encountered in identification and analysis of the model. Therefore, there is a strong need to explore new alternatives and this is the objective of this paper. By transforming a fuzzy number to a real number via integrating the inverse of the membership function, new autoregressive models can be developed to fit the observation values of a fuzzy time series. With the new models, the issues of model identification and parameter estimation can be addressed; and trends, seasonalities and multivariate fuzzy time series could also be modeled with ease. In addition, asymptotic behaviors of fuzzy time series can be inspected by means of characteristic equations.

This paper describes the development of adult authentication system using numerical recognition. Nowadays, the automats are very popular and they are dealing in many item suck as coffee, soft drinks, alcoholic drinks and cigarettes, etc. Among these items, some are harmful to the minor, and so the sale of these to the minor must be prohibited. In relation to this, adult authentication system is required to be equipped to the automat which deals in items harmful to minor. According to these demands, we develop the adult authentication system. This system capture the image of a residence certificate card by the identification card-reader, and recognize its numbers and identify it as adult or minor by main computer, where numeral recognition is accomplished by using image processing methods and neural network recognizer. The characteristic test of the system is carried out, and its result reveals that the system has the error of less than 1%. Thus, It is thought that the system can be used for identifying adult in the automats.

In this study, we proposed the fuzzy modeling method and designed a model-based logic controller for Activated and Sludge Process(A.S.P.) in sewage treatment. The identification of the structure of fuzzy implications is carreid out by use of fuzzy c-means clustering algorithm. And to identify the parameters of fuzzy implications, we used the complex and the least square method. To tune the premise parameters automatically the complex method is implemented. The model-based fuzzy controller is designed by rules generated from the identified A.S.P. fuzzy model. The feasibility of the proposed approach is evaluated through the identification of the fuzzy model to describe an input-output relation of the A.S.P.. The performance of identified model-based fuzzy controller is evaluated through the computer simulations.
