Transporting a large table using multiple robotic agents requires at least two group behaviors of homing and herding which are to bo coordinated in a proper sequence. Existing GP methods for multi-agent learning are not practical enough to find an optimal solution in this domain. To evolve this kind of complex cooperative behavior we use a novel method called fitness switching. This method maintains a pool of basis fitness functions each of which corresponds to a primitive group behavior. The basis functions are then progressively combined into more complex fitness functions to co-evolve more complex behavior. The performance of the presented method is compared with that of two conventional methods. Experimental results show that coevolutionary fitness switching provides an effective mechanism for evolving complex emergent behavior which may not be solved by simple genetic programming.

The purpose of this study is to analyze the structural relationship between customer's pleasure, customer satisfaction, switching cost, and relationship commitment using the fitness center and provide implications. Specifically, this study aims to investigate the effect of the degree of customer's awareness of pleasure on the relationship commitment through the medium of customer satisfaction and switching cost. For this purpose, the structural equation model was constructed based on the previous studies, and the exogenous variables were pleasure, and the endogenous variables were customer satisfaction, switching costs and relationship commitment. The subjects of this study were customers who used fitness centers in the metropolitan area. The sampling method for the sample survey was a total of 277 people using convenience sampling. 257 copies were used as final data except for 20 samples that were not appropriate for the study. The statistical program for data analysis was IBM SPSS Ver. 26.0 and Amos 21.0. The specific data processing method is as follows: First, frequency analysis was conducted to understand the general characteristics of the subjects. In order to verify the validity and reliability of the research tools, confirmatory factor analysis and reliability analysis were conducted. In order to understand the theoretical relationship between each variable, structural equation model was conducted. The results of data processing on the research model are as follows: First, the pleasure of the fitness center customers had a positive effect on customer satisfaction. Second, customer satisfaction had a positive effect on the switching costs. Third, customer satisfaction had a positive effect on the customer commitment. Fourth, switching costs had a positive effect on customer commitment.

The purpose of this study was to understand interrelationships among switching costs, customer satisfaction, and switching intent in a family restaurant. Based on a total of 427 customers obtained from empirical research, this study reviewed the reliability and fitness of the research model and verified a total of five hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model (SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=137.881 (df=50); p< .001; CMIN/df 2.758; GFI= .947; AGFI= .919, NFI= .965; IFI= .978; TLI= .970; CFI= .978; RMR= .047; RMSEA= .064. The results showed that switching cost (${\beta}$= .123) in a family restaurant had a positive (+) influence upon customer satisfaction. Further, switching cost had a significantly negative (-) effect on switching intent (${\beta}$= -.414). In addition, there were moderating effects related to customer knowledge and variety seeking orientation in terms of the causal relationships between switching costs, customer satisfaction, and switching intent. Limitations and future research directions are also discussed.

The purpose of this study was to categorize brand-switching behaviors into subdivided groups by variety seeking and perceived differences between brands and to compare and to analyze brand-switching motive perceived differences between brands clothing-involvement and buying price among the subdivided groups. The subjects were 343 female and male to have jean pants-buying experience in their age of 20-29 living in Seoul and Kyunggi province. For the analysis of the data mean frequency t-test $\chi^2$-Test Factor analysis MANOVA Duncan-test were conducted and the cronbach's $\alpha$ has been calculated to measure the reliability The results are as follows: 1. brand-switching behaviors are categorized into 4 groups by strength of variety-seeking and perceived differences between brands that are small or large which are habitual brand switchers internal derived brand-switchers external derived brand-switchers and combined derived brand-switchers. 2. Among the 4 sub-groups there were significant difference in brand-switching motive according to factors such as change-seeking needs and price & promotion. And there were significant differences in perceived differences between brands according to factors such as apparel design clothing -symbolism fitness except apparel shop. 3. According to strength of variety-seeking levels of clothing-involvement and buying price have increased Combined derived brand-switchers have totally the strongest variety-seeking and the highest clothin-involvement and they purchase the highest priced jean-pants of the other types of consumers.

Many multiagents cooperative problems, such as table transport problem, require several emergent behaviors and a proper coordination of these is essential for successful accompishment of the task. We study in this paper the genetic programming method, called fitness switching, to evolve cooperation strategies of robots in these kind of tasks and show simulation results to demonstrate its effectiveness.

The purpose of this study was to understand the interrelationships among customers'perceived values, switching cost, and loyalty to a family restaurant. Based on 328 patrons obtained from empirical research, this study reviewed the reliability and fitness of a research model and verified three hypotheses using the Amos program. The hypothesized relationships were tested in the model simultaneously using a structural equation model (SEM). The proposed model provided an adequate fit to the data, $x^2$=341.01 (df=154), p<0.001, CMIN/df 2.21, GFI 0.91, NFI 0.94, IFI 0.97, TLI 0.96, CFI 0.97, RMSEA 0.06. The results showed that utilitarian values (${\beta}$=0.27) as customers' perceived values elements in a family restaurant, had a positive (+) influence upon switching cost. Switching cost had a significant positive (+) effect on the behavioral loyalty (${\beta}$=0.16) and attitudinal loyalty (${\beta}$=0.16). Hedonic values (${\beta}$= 0.41) and utilitarian values (${\beta}$=0.26) had a positive (+) influence on customer's behavioral loyalty. Additionally, a customers hedonic values (${\beta}$= 0.30) and utilitarian values (${\beta}$=0.32) had a significant positive (+) effect on attitudinal loyalty. Limitations and future research directions are also discussed.

이 연구의 목적은 영업사원의 이직을 조장/억제하는데 영향을 미치는 요인들을 규명하는데 있다. 이를 위해 생명보험회사에 종사하고 있는 영업사원을 대상으로 실증분석을 통해 영업사원의 직무성과, 직무스트레스와 이직의도 간의 인과관계를 검증하였다. 구체적으로 직무성과와 직무스트레스가 이직의도에 미치는 영향에서 직무갈등의 매개적 효과와 직무교육 및 전환손실의 조절적 역할에 대해 검증하는데 연구의 초점을 맞추었다. 실증분석 결과 직무성과가 높을수록 직무갈등이 감소하고, 직무스트레스가 증가할수록 직무갈등도 높아지는 것으로 나타났으며, 직무갈등을 통해 이직의도에 영향을 미치는 것으로 나타났다. 직무교육과 전환손실의 조절적 역할을 분석한 결과 직무 교육을 많이 받은 영업사원이 적게 받은 영업사원에 비해 직무성과가 직무갈등에 미치는 부(-)적 효과가 더 강한 것으로 나타났지만, 직무스트레스가 직무갈등에 미치는 효과에 대해서는 직무교육이 조정적 역할을 하지 못하는 것으로 나타났다. 마지막으로 직무갈등이 이직의도에 미치는 영향에 있어 전환손실이 조절적 역할을 하는 것으로 나타났다.

국내 대형마트 점포 수는 2008년 기준 403개로 포화시점에 근접하고 있다. 이러한 경쟁상황에서 '점포충성도(store loyalty)'가 지속적 경쟁우위를 위한 전략적 도구로써 그 활용성이 점점 더 중요시 되고 있다. 다양한 관점에서 점포충성도를 대형마트 연구의 핵심적 과제 다루어왔으나, 통합적인 연구 접근 방법이 미흡한 실정이다. 따라서 본 연구에서는 통합적 관점에서 점포충성도가 형성되는 두 가지 경로를 제안하였다. 이중경로모형은 첫째, 내재적 경로 '서비스품질$\rightarrow$고객만족$\rightarrow$점포충성도', 둘째, 외재적 경로 '점포개성$\rightarrow$점포동일시$\rightarrow$점포 충성도'로 구성된다. 조사대상은 대형마트를 이용하는 소비자들을 대상으로 진행하였으며, 구조방정식모형 분석을 통하여 제안된 이중경로모형의 적합성 및 가설검증을 실시하였다. 연구결과, 모형의 적합지수들은 상당히 좋은 값들을 보여주고 있다. 또한 본 연구에서 새롭게 제시된 내재적 경로인 서비스품질은 고객만족에 정의 영향을 미치고, 고객만족은 결과변수인 대형마트의 점포충성도에 매우 유의하게 영향을 준 것으로 나타났다. 그리고 외재적 경로에서 대형마트의 점포개성은 점포동일시에 긍정적인 영향을 주고 매개변수인 점포개성은 점포충성도에 영향을 미치는 것으로 나타났다. 이를 통해 본 연구는 대형마트의 점포충성도 형성에 관한 두 가지 경로를 제시함으로써, 이론적, 관리적 시사점을 도출하였고 연구의 한계점과 미래연구방향을 제시하였다.
