  • This paper deals with space Beltrami system with three characteristic matrices in even dimensions, which can be regarded as a generalization of space Beltrami system with one and two characteristic matrices. It is transformed into a nonhomogeneous $p$-harmonic equation $d^*A(x,df^I)=d^*B(x,Df)$ by using the technique of out differential forms and exterior algebra of matrices. In the process, we only use the uniformly elliptic condition with respect to the characteristic matrices. The Lipschitz type condition, the monotonicity condition and the homogeneous condition of the operator A and the controlled growth condition of the operator B are derived.

  • This study investigated the basic data of architectural design about framework dimensions inherent in a folk house of Yeosu city generally and systematically. We investigated the common dimensions of framework constitution for folk house (main building) seen a lot in Yeosu city. Most of the folk houses in Yeosu city were common people houses built from the end of 19th century to the 1960s and have maintained the same style for a long time. As a result of the study, common dimensions were calculated in two ways. One is Front toi/3ryang house and the other is Front/back toi/2kozu5ryang house. Front/back toi house was large in the case of full width, total height, and member thickness but, width of the front kan is no big difference. In other words, the scale of Front toi house and Front/back toi house is difference only in the rest except front kan (width). Among calculated common dimensions, the front kan of Front toi house and Front/back toi house in the plan, the kitchen is the widest, and the size is the same at 8.7 chucks degree. The next became small little by little in order of room 1(main room), room 2(center room), room 3(end room). As a result, the size of the room 3 of Front toi house reaches 7.7 chucks, and room 3 of Front/back toi house reaches 8.0 chucks. In the section dimensions, pillar height is in sum of floor height and pillar core height, Front toi house is 7.9 chucks, and Front/back toi house is 8.2 chucks. The investigation of basic data of architectural design is not only makes possible to grasp specific and simple to three-dimensional universal aspect on framework dimensions, but also documentation of folk house design know-how is done, and the architectural design standards of Korean folk house is written in the contents according to the area.

  • This study intended arousal of other viewpoints that deal with and understand spaces and shapes, by describing the concept of 'dimensions' into visual patterns. Above all, the core concept of spatial dimensions was defined as 'expandability'. Then, first, the 'golden ratio', 'Fibonacci sequence', and 'fractal theory' were defined as elements of each dimension by stage. Second, a 'unit cell' of one dimension as 'minimum unit particles' was set. Next, Fibonacci sequence was set as an extended concept into two dimensions. Expansion into three dimensions was applied to the concept of 'self-similarity repetition' of 'Fractal'. In 'fractal dimension', the concept of 'regularity of irregularity' was set as a core attribute. Plus, Platonic solids were applied as a background concept of the setting of the 'unit cell' from the viewpoint of 'minimum unit particles'. Third, while 'characteristic patterns' which are shown in the courses of 'expansion' of each dimension were embodied for the visual expression forms of dimensions, expansion forms of dimensions are based on the premise of volume, directional nature, and concept of axes. Expressed shapes of each dimension are shown into visually diverse patterns and unexpected formative aspects, along with the expression of relative blank spaces originated from dualism. On the basis of these results, the 'unit cell' that is set as a concept of theoretical factor can be defined as a minimum factor of a basic algorism caused by other purpose. In here, by applying diverse pattern types, the fact that meaning spaces, shapes, and dimensions can be extracted was suggested.

  • The dimensions of affection structure from hand movements was developed for the purpose of understanding relationship between affective words and physical factors to apply it to computing environment. To analyze hand movements, three dimensions -direction, time, weight- were found through reconstructing sub-properties of Laban Movement Analysis. The direction dimension has five freedoms of movement (horizontal, vertical, sagittal, circular, shaking) while the time and weight dimensions both have two sub categories each, (sudden, sustained), (light, strong) respectively. By factorial design using the three dimensions, twenty movement were videotaped. Participants rated a list of fifty korean affective words on each twenty movements. The results were studied by nonlinear principal component analysis. The results suggested that time and weight dimensions are closely related with arousal level dimension of affection. Strong and sudden movements associated with highly aroused affection, while light and sustained movements associated with the opposite affection. The direction sub-dimensions were found to be associated with the kinds of affection. Linear movements like horizontal, vortical and sagittal direction were correlated to highly aroused negative affection. Circular movements were found to correlate closely by fun and delight on the graph, while shaking movements were correlated to anxiety and impatience. These results imply that the dimensions of affection structure and sub-properties of hand movements are closely connected with each other.

  • Parametric bodies reproduce the actual shape of human body parts and should be convenient for general users to change size to judge the visual fit of clothes on-line. In this study, three parametric bodies(i.e. I, C, D ) were compared to verify the accuracy of the provided body dimensions and reproducibility to a target model. To compare reproducibility, the 20s female standard virtual model developed for an apparel industry by Korean agency for technology and standards is used. The investigation of existing parameters showed that the numbers and kinds of parameters provided by each program were different with some errors in notation; in addition, some of virtual body dimensions went beyond the maximum allowable error. The result of changing each parametric body to the 20s female standard body showed that D, C, I in order produced better reproducibility for body dimensions. There were different levels of protrusion and concavity in the virtual cross sections and virtual longitudinal sections despite the small differences in body dimensions and cross sectional areas; in addition, some parametric body was not bilateral symmetry. The results of this study can be used as basic information in the standardization of a virtual model used in a virtual garment program.

  • Brand equity is the added value endowed by the brand to the product. This concept born in the 1980's has aroused intense interest among market managers and business strategists from a wide variety of industries. Brand equity can be approached in different perspectives according to the motivations and the objectives of the studies. Consumer-based brand equity is examined internally by consumers' cognition and feeling and externally by consume behavior in the market By analyzing the relationship between them we can understand how brand value is made in the mind of consumers and how it is converted into the consumer behavior,. The brand is an especially important extrinsic cue in clothing products and the apparel industry has higher brand equity when it is actually compared with the brand equity of many other industries measured as a financial asset. Therefore the purpose of this study was to find out brand value of clothing products through clothing brand equity and to understand consumer behavior of the brand. And so we focused in consumer-based brand equity. For the empirical study three brands that are predicted to have different level of brand equity were selected based on prices and market shares of the brands. As the result the consumer-based brand equity is composed of emotional and cognitive dimensions and each dimension has several sub-dimensions. These diverse dimensions of brand equity bring about differences in consumers' purchase behavior market share and price premium of brands.

  • Reverse engineering involves duplicating a physical part by measuring and analyzing its physical dimensions, features, and material properties. By combining reverse engineering with three-dimensional (3D) printing, engineers can simply fabricate and evaluate functional prototypes. This design methodology has been attracting increasing interest with the advent of the Fourth Industrial Revolution. In the present study, we apply reverse engineering and 3D printing technologies to evaluate a fabricated automotive inner ring prototype. Through 3D printing, inner rings of various densities were prepared. Their physical dimensions were measured with a 3D scanning system. Of our interest was the effect of inner ring density on the physical dimensions of the fabricated prototype. We compared the design dimensions and physical dimensions of the fabricated prototypes. The results revealed that even the 20% density of inner ring was effective for 3D printing in terms of satisfying the design requirements.

  • Purpose - This study aims to conceptualize the construct of social media (SM) fatigue. Design/methodology/approach - A qualitative approach is employed to understand how SM users currently perceive (or interpret) the goals of SM usage and to conceptualize SM fatigue and its dimensions. We collected data through in-depth interviews of three SM users and group discussions among eighty SM users. Findings - we draw a definition of SM fatigue from a resource view that excessive SM use might lead to SM fatigue by depleting the internal resources of SM users. Further, through the analysis of the qualitative data from interviews and group discussions, we find the multi-dimensional nature of SM fatigue and identify five dimensions of SM fatigue-fatigue from the social obligation to interact with people, the importance of self-appearance, the quality of information, the quantity of information, and undesirable events-and common sources of fatigue in each dimension. Research implications or Originality - The conceptualization of SM fatigue elaborated in this study could enable scientific exploration of the role of SM fatigue in users' attitudes or behavior formation and change. On a practical front, this study would be valuable to companies by facilitating systematic investigations of their customers' fatigue through the lens of the SM fatigue dimensions.

  • Purpose: The study's objective was to examine the impact of brand personality dimensions on consumer behavior for laptop purchases in Nepal. Research Materials and Methods: The study included descriptive and explanatory research designs. A structured questionnaire with a purposive sampling method was employed to gather the necessary information for the study. The survey data were analyzed using a quantitative approach. The study used descriptive statistics to characterize the response conditions. Correlation analysis was used to investigate the relationship between brand personality dimensions and consumer behavior. Regression path analysis was employed to identify the effect of brand personality dimensions and consumer behavior. Results: The result of regression path analysis showed that the three dimensions - competency, ruggedness, and sophistication, have a significant effect on consumer behavior, and the two dimensions- sincerity and excitement do not have a substantial impact on consumer behavior in laptop buying in Nepal. Conclusions and Implications: Such findings can serve as pioneering empirical evidence and provide a framework for marketers and future studies in various scenarios. The study's findings can help marketing managers in handling information management. Manufacturers, wholesalers, and retailers can also use the results in formulating marketing strategies, and marketers need to be aware of such considerations for influencing consumer behavior.
