This paper offers the theory and method for regression analysis of the regression model with operational parameter variables based on the fundamentals of mathematical statistics. Regression coefficients are usually constants related to the problem of regression analysis. This paper considers that regression coefficients are not constants but the functions of some operational parameter variables. This is a kind of method of two-step fitting regression model. The second part of this paper considers the experimental step numbers as recursive variables, the recursive identification with unknown operational parameter variables, which includes two recursive variables, is deduced. Then the optimization and the recursive identification are combined to obtain the sequential experiment optimum design with operational parameter variables. This paper also offers a fast recursive algorithm for a large number of sequential experiments.

Reengineering to object-oriented system is needed to maintain the system and satisfy requirements of structure change. Target systems which should be reengineered to object-oriented system are difficult to change because these systems have no design document or their design document is inconsistent of source code. Using design document to identifying objects for these systems is improper. There are several researches which identify objects through procedural source code analysis. In this paper, we propose automatic object identification method based on clustering of VTFG(Variable-Type-Function Graph) which represents relations among variables, types, and functions. VTFG includes relations among variables, types, and functions that may be basis of objects, and weights of these relations. By clustering related variables, types, and functions using their weights, our method overcomes limit of existing researches which identify too big objects or objects excluding many functions. The method proposed in this paper minimizes user's interaction through automatic object identification and make it easy to reenginner procedural system to object-oriented system.

본 연구는 K항공사를 이용하는 고객을 대상으로 고객가치가 브랜드 동일시 및 충성도에 미치는 영향관계를 분석하고자 연구모형을 설정하였다. 이론연구의 고찰을 통해 변수를 추출하였으며 각 변수간의 관계를 살펴보기 위해 구조방정식 모형을 활용하였다. 실증분석 결과는 아래와 같다. 첫째, 고객가치 중 기능적 가치와 감성적 가치가 브랜드 동일시에 모두 유의한 영향을 미치는 것으로 나타나 가설 1은 채택되었다. 둘째, 현재의 소비자는 제품이나 서비스의 선택에 있어 감성적인 면을 더 추구한다는 것을 확인하였다. 즉 자아 이미지와 동일하거나 자신의 가치관 혹은 라이프 스타일에 일치한다고 생각하는 항공사 브랜드를 이용함으로써 항공사와의 브랜드 동일시를 추구하고 있다. 셋째, 고객 가치 중 기능적 가치와 감성적 가치 모두 브랜드 충성도에 영향을 미치지 않는 것으로 나타나 고객가치는 브랜드 동일시를 통해 충성도가 강화됨을 알 수 있다. K항공은 소비자들의 브랜드 충성도를 상승시키기 위해서는 다른 매개변수의 역할도 고려되어야 하겠지만 고객의 브랜드 동일시 제고에 관심을 가져야 할 것으로 사료된다.

The static state estimation are divided into two groups; estimation and detection & identification. This paper centers on detection and identification algorithm. Especially, the identification of line errors is focused on and is performed by the extended W.L.S. algorithm with line swithching states. Here, line switching states mean the discrete values of line admittance which are influenced by unexpected line switching. The numerical results are obtained from the assumption that the noise vector is independent zero mean Gaussian random variables.

In this paper, the kinematic and dynamic analyses of spatial complex kinematic chain are studied. Through the new method both using the set of identification numbers and applying the DenavitHartenberg link representation method to the spatial complex kinematic chain, the kinematic configuration of the chain is represented. Some link in the part of closed chain being fictitiously cutted, the complex kinematic chain is transformed to the branched chain. The kinematic constraint equations are derived from the constraint conditions which the cutted sections of the link have to satisfy. And the joint variables being partitioned in the independent joint variables and the dependent joint variables, the dependent variables are calculated from the independent variables by using the Newton-Raphson iterative method and the pseudoinverse matrix. The equations of motion are derived under the independent joint variables by using the principle of virtual work. Algorithms for dynamic analysis are presented and simulations are done to verify accuracy and efficiency of the algorithms.

We propose a multi-objective space search algorithm (MSSA) and introduce the identification of fuzzy inference systems based on the MSSA and information granulation (IG). The MSSA is a multi-objective optimization algorithm whose search method is associated with the analysis of the solution space. The multi-objective mechanism of MSSA is realized using a non-dominated sorting-based multi-objective strategy. In the identification of the fuzzy inference system, the MSSA is exploited to carry out parametric optimization of the fuzzy model and to achieve its structural optimization. The granulation of information is attained using the C-Means clustering algorithm. The overall optimization of fuzzy inference systems comes in the form of two identification mechanisms: structure identification (such as the number of input variables to be used, a specific subset of input variables, the number of membership functions, and the polynomial type) and parameter identification (viz. the apexes of membership function). The structure identification is developed by the MSSA and C-Means, whereas the parameter identification is realized via the MSSA and least squares method. The evaluation of the performance of the proposed model was conducted using three representative numerical examples such as gas furnace, NOx emission process data, and Mackey-Glass time series. The proposed model was also compared with the quality of some "conventional" fuzzy models encountered in the literature.

Purpose: This study aims to verify whether avatars that embody different brand concepts offer different experiences to users. Furthermore, this study explores the relationship between user identification with avatars and their actual brand purchase intentions. Research design, data and methodology: The research design employed a between-subjects approach, with two independent variables: brand concept and avatar. The measured dependent variables were brand experience in extended reality (XR) and purchase intention. Additionally, brand attitude served as a control variable. Results: First, in virtual brand spaces with symbolic benefits, ideal avatars were found to elicit higher levels of brand experience than actual avatars. Specifically, participants reported elevated levels of entertainment and relational assembly experiences in symbolic brand spaces. Second, this research reveals that the relationship between users' identification with avatars and their intention to make actual brand purchases is mediated by brand experience in XR. Conclusions: The findings suggest that ideal avatars evoke higher levels of brand experience within symbolic brand spaces, particularly in entertainment, relational connection, and a sense of community. Furthermore, this study establishes the role of brand experience in XR as a mediator between avatar identification and purchase intentions.

Objectives : The aim of this study was to determine the relationship between the core properties of professional socialization and social status satisfaction, economic reward satisfaction, and subjective class identification. Methods : Medical knowledge and skill, autonomy, and professional value factors were used as essential properties of professional socialization to determine the association with job satisfaction and subjective class identification. The authors used a self-administered questionnaire survey and collected nationwide data between July and August 2003, with 211 responses used for final analysis. Results : 'Age' and 'trust and respect' were positively associated with social status satisfaction, and 'occupation' was negatively associated. 'Income' and 'trust and respect' were positively related to economic reward satisfaction, and 'practicing for oneself', and 'a sense of duty and attendance' were negatively related. 'Practicing for oneself', 'not believing explanations', and 'a sense of duty and attendance' had a positive relationship with subjective class identification. 'Income', 'knowledge system', 'medical mistakes', 'treating like goods', 'meaning and joy', and 'trust and respect' had a negative relationship. Conclusions : The core property variables of professional socialization had a different relationship with social status satisfaction, economic reward satisfaction and subjective class identification. In particular, many core property variables were associated with subjective class identification positively or negatively. The development of professional socialization would help promote job satisfaction and subjective class identification.
