In this paper, we propose two kinds of chaos dimensions, the fuzzy correlation and fuzzy Lyapunov dimensions, for speaker recognition. The proposal is based on the point that chaos enables us to analyze the non-linear information contained in individual's speech signal and to obtain superior discrimination capability. We confirm that the proposed fuzzy chaos dimensions play an important role in enhancing speaker recognition ratio, by absorbing the variations of the reference and test pattern attractors. In order to evaluate the proposed fuzzy chaos dimensions, we suggest speaker recognition using the proposed dimensions. In other words, we investigate the validity of the speaker recognition parameters, by estimating the recognition error according to the discrimination error of an individual speaker from the reference pattern.

The objectives of this study were to explore theoretically the factors that were associated with role conflict of rural extension educators, to investigate the consequences of this conflict, and to suggest possible solutions to the role conflict. This study was carried out through literature review. The findings from this study were as follows : 1) The causes of role conflict were divided into individual characteristics and social or organizational characteristics. Existing research papers examining the cause of rural extension educators' role conflict had focused mainly on individual characteristics. Therefore, social characteristics of the role conflict should be included in future research activities. 2) The consequences of role conflict were made up of individual dimensions and organizational dimensions. However, pervious researches on rural extension educators' role conflict had dealt with the individual dimensions only. Therefore, the consequences of organizational dimensions should be added to future researches. 3) Revision of roles and job specifications, developing professional competencies, and raising achievement motivation were some of the possible solutions to rural extension educators' role conflict. These solutions, if managed effectively, may improve the performance of extension organizations, as well as that of the individuals by solving the role conflict of rural extension educators.

Purpose: The Covid-19 pandemic has accelerated and triggered changes in online shopping especially in an emerging market. This paper develops a modification of SERVQUAL model to examine the relationship between individual dimensions of e-service quality, online trust and purchase intentions in singular online shopping platform. Research design, data and methodology: Data from an online survey of 385 Lazada's shoppers were used to test the research model. The structural equation modeling technique was performed to test the research model. Results: The analytical results revealed that five dimensions of e-service quality were positively correlated with one another whereas some dimensions were negatively correlated with purchase intentions. The results of this study provide new insight into the literature as well as practical implications for marketers especially in Thai online market. Conclusion: This study develops the instrument dimensions of e-service quality through modifying the SERVQUAL model to examine the e-commerce context and to testify how these individual dimensions are interlinked with one another. It also suggests that responsiveness has two-sided affects that in responses which are too prompt and insistent could make the customer feel uncomfortable and perhaps ending up with no interaction and transaction.

The fractal study in river basin has been performed for the sinuosity of an individual stream and bifurcation of the stream network. The previous studies has suggested many methods or equations for the fractal dimension estimation in a river network. This study used those many equations for the estimation of fractal dimensions on the streams such as Bokha, Gonjiam, and Pocheon streams. The estimated dimensions are in the range of 1 to 1.359 for the individual stream and 1.634 to 2 for the stream network. The most of equations were suggested based on the assumption of self-similarity of a river basin for the individual stream and stream network. However, the real river basin could be characterized by self-affinity rather than self-similarity. Even though we estimate the dimensions by using many equations, we could not recommend which one is better equation for the estimation of fractal dimension. This might be from the self-similarity assumption of equations. Therefore, the assumption and research work of self-affinity will be needed for the appropriate estimation of fractal dimension in river basin.

Social capital contains relational, structural and cognitive dimensions. This study regards social capital as diminishing factor in innovation resistance. Trust, structuring individual tie and vision sharing which are representatives of three dimensions of social capital diminish innovation resistance. So innovation becomes more successful.

In modern manufacturing, a product consists of many components created by different processes. Variations in the individual component dimensions and in the processes may result in unacceptable final assemblies. Thus, engineers have increased pressure to properly set tolerance specifications for individual components and to control manufacturing processes. When a proper variation stack-up analysis is not performed for all of the components in a functional system, all component parts can be within specifications, but the final assembly may not be functional. Thus, in order to improve the performance of the final assembly, a proper variation stack-up analysis is essential for specifying dimensional tolerances and process control. This research provides a detailed case example of the use of variation stack-up analysis using a Monte Carlo simulation method to improve the defect rate of a complex process, which is the commutator brush track undercut process of an armature assembly of a small motor. Variations in individual component dimensions and process mean shifts cause high defect rate, Since some dimensional characteristics have non-normal distributions and the stack-up function is non-linear, the Monte Carlo simulation method is used.

This study attempted to identify not only dimensions of clothing brand experience, but dimensions of perceived consumer-brand relationship. In addition, this study investigated the relationships among clothing brand experience, consumer-brand relationship and brand loyalty. 354 questionnaires were distributed to female and male respondents aged 20 to 30, and then analyed by SPSS and AMOS program. The results were as follows. First, it was identified that the dimension of clothing brand experience was composed of two dimensions; individual experience(personal dimension) and relational experience(social cultural dimension). Second, the type of consumer-brand relationship was found out as three dimensions; interdependence, love and passion, and partner. Third, these results showed that individual and relational experience of clothing brand was the most influential factor for love and passion dimension of consumer-brand relationship. Forth, love and passion dimension through clothing brand experience was the most influential factor for brand loyalty. Above results imply that the key of strong brand relationship lies in the emotion of love such as human relationship.
