  • When designing a gerotor, designers determine basic dimensions of a gerotor with transmitted power considering strength, interference and so on. But, designers can not easily obtain the tooth profile generated by dimensions as well as the geometry of generating hob for cutting the tooth profile. In order to resolve these problems, an automatic design system creating not only the solid model of a gerotor but also that of the generating hob using the design parameters of dimensions is developed. Through the developed system, designers can improve the efficiency of design and satisfy the variable requirements of design as well. In this research, the three-dimensional solid model of gerotor is generated considering the design parameters. Besides, that of generating hob with respect to the design parameters of hob is created automatically. The system is developed using Visual Basic and its three-dimensional geometric modeling module is constructed using SolidWorks.

  • This research examines the impact of brand personality dimensions on store attitude and store loyalty for department stores. A total of 431 customers participated in the online survey. The participants were women in their 20's to 50's with experience of purchasing apparel from four major department stores. The data were analyzed using factor analysis, reliability test, and structural equation modeling with PASW 18.0 and AMOS 18.0. Analyses revealed three dimensions of the brand personality of department stores: prestige, passion, and sincerity. Among the three dimensions of brand personality, 'passion' and 'sincerity' were shown to be the most influential factors affecting department store attitude. The results suggest that passionate and sincere customers tend to exhibit favorable store attitudes. Customers with more favorable store attitudes then are more likely to express great store loyalty than those with less favorable attitudes. An analysis of the effect of brand personality on attitudes toward department stores provides implications for department store brand management strategies.

  • Business firms and consumers exist within a society, and their activities influence a society, because they are not separated from a society. Thus, consumers as well as business firms have been asked to conduct socially responsible actions (i.e., environmentally friendly production and socially friendly activities). Previous researchers have investigated on the relationship between corporate social responsibilities and business performances. For example, researchers have analyzed the effects of corporate social responsibility on consumer's corporate evaluations. The corporate social responsibility is commonly classified into the three dimensions (economic, social, and environmental responsibility). In this paper, we demonstrated that the consumer social responsibility can also be classified into the three dimensions. Previous researchers have shown that the three dimensions of corporate social responsibility influence consumer's corporate evaluation. However, they have not considered the interaction effect of the corporate social responsibility and the consumer social responsibility on consumers' corporate evaluation. Different from the past studies, this study investigated on the interaction effect of consumer social responsibility (economic, social, environmental responsibility) and corporate social responsibility (economic, social, environmental responsibility) on consumer's corporate evaluation. For the study, we collected survey data of 200 consumers and analyzed the interaction effect with ANOVAs. The result showed that the three dimensions of social responsibility to both corporate and consumers influence positively the corporate evaluation. They also showed that the interaction effect of consumer responsibility and corporate responsibility on the corporate evaluation was statistically significant. This implies that it is necessary for corporate to conduct corporate social responsibility differently depending on consumer's activity for consumer social responsibility.

  • This paper investigates the effect of the width of failure and tension crack (TC) on the stability of cohesive-frictional soil slopes in three dimensions. Working analytically, the slip surface and the tension crack are considered to have spheroid and cylindrical shape respectively, although the case of tension crack having planar, vertical surface is also discussed; the latter was found to return higher safety factor values. Because at the initiation of a purely rotational slide along a spheroid surface no shear forces develop inside the failure mass, the rigid body concept is conveniently used; in this respect, the validity of the rigid body concept is discussed, whilst it is supported by comparison examples. Stability tables are given for fully drained and fully saturated slopes without TC, with non-filled TC as well as with fully-filled TC. Among the main findings is that, the width of failure corresponding to the minimum safety factor value is not always infinite, but it is affected by the triggering factor for failure (e.g., water acting as pore pressures and/or as hydrostatic force in the TC). More specifically, it was found that, when a slope is near its limit equilibrium and under the influence of a triggering factor, the minimum safety factor value corresponds to a near spherical failure mechanism, even if the triggering factor (e.g., pore-water pressures) acts uniformly along the third dimension. Moreover, it was found that, the effect of tension crack is much greater when the stability of slopes is studied in three dimensions; indeed, safety factor values comparable to the 2D case are obtained.

  • This study aimed to identify the dimensions of benefits and costs that consumers perceive in utilizing locationbased applications (LBAs) on smartphones, and to distinguish consumer groups according to their perceptions of those benefits and costs. A web-based consumer survey was conducted-among consumers who had experience using LBAs. Four hundred participants were 20's to 40's, with 200 women and 200 men. Descriptive statistics, frequency analysis, t -tests, one-way analysis of variance, and cluster analysis were used for data analysis. The findings of this study are as follows: first, LBAs accounted for about 20% of the smartphone apps used by consumers. Second, factor analysis identified the underlying dimensions of the benefits and costs of smartphone LBAs. The underlying dimensions of benefits perceived by consumers were information/economic/convenience, entertainment and personalization. Privacy concerns, lack of trust and lack of behavioral control were the underlying dimensions of the perceived costs of LBAs. Third, ANOVA showed that the perceived benefits and costs of smartphone LBA services differed according to the characteristics of the consumer. Cluster analysis identified three distinctive consumer groups according to the levels of perceive costs and benefits of smartphone LBAs. The three groups were labeled the 'benefit-cost balanced group,' 'cost centered group,' and 'benefit centered group.'

  • Sizing system of Korean structural firefighting protective clothing that is national approved should be met for specification of structural firefighting protective clothing that is identified by Ministry of Public Administration and Security(MOPAS). However if you look over the specification of sizing system, the standard is based on only 'height' and the others are indicated as the size of completed product. KS K ISO 13688 and EN 340 which is met on ISO 13688 which indicates sizing system about protective clothing has the standards of height, chest and waist circumference. Also NFPA 1971 that has standards of sizing system is based on chest circumference, cervical to wrist length, waist circumference and inseam. That is different from Korean standards. Therefore, fire fighting protective clothing standards which is based on only height should be compensated and not be relied on foreign standards like ISO. It is indispensable for developing our own sizing system of structural fire fighting protective clothing. In this studying, Korean new sizing system of structural fire fighting protective clothing was developed for providing basic information of ergonomic structural fire fighting protective clothing. The analyzed target age was between 20 and 59 years old fire fighter who extinguish the fire. And it was analyzed by 3D measurement among data of the $5^{th}$ Size Korea. On conclusion, in case of structural fire fighting protective clothing coat, physical dimension was to be chest circumference, cervical to wrist length. Three dimensions as 5cm space of circumference and four dimensions as 2.5cm space of cervical to wrist length were derived, which means that totally 12 dimensions were defined. Dimension standards of pants was based on the analysis of waist circumference and crotch height. Six dimensions as 5cm space of waist circumference and three dimensions as 5cm space of crotch height were derived, which means that totally 14 dimensions were defined.

  • Three Eum and Three Yang[三陰三陽] is a way of studying the changing of nature from a Eum(陰) and Yang(陽) point of view, Juhakhae(周學海) divides this into two dimensions. The first is the concept of dividing the exterior part of the body excluding the organ into 6 divisions as Eumyang(陰陽) of front and rear characteristic. The second is the concept of dividing the systematic bio-activity of the central organ into another 6 dimensions. The former concept is illustrated in the body as a certain meridian controlling a certain field of the body, while the latter is presented as a certain organ performing an activity of Gi(氣). Three Eum and Three Yang[三陰三陽] is not based on fixed substances. but it is a thought process model of observing the structural-functional changes of the body in disease state. Therefore, by understanding Three Eum and Three Yang[三陰三陽] of field and activity of Gi(氣) respectively and comprehensively putting these into practice, we will be able to approach the essence of the disease state in a more precise manner.
