Cross-border online shopping is an example of non-mobile transnational consumption behavior that has become more popular over the last decade due to the development of technology and transportation. Based on the Theory of Reasoned Action(TRA), this study proposed and tested the hypothesized model that would explain the relationships among consumption beliefs, attitudes toward cross-border online shopping, subjective norms, and purchase intention. Consumption beliefs were measured by global consumption orientation, consumer orientation, and global brand beliefs. In addition, subjective norms included two types: online and offline norms. Descriptive statistics and path analysis were employed for the analysis of the dataset of 174 participants. As a result, the hypothesized model was generally supported. Consistent with the hypothesis, global consumption orientation and global brand beliefs were positively related to positive attitudes toward cross-border online shopping but negatively associated with consumer ethnocentrism. Offline subjective norms positively predicted both the attitudes and purchase intention whereas online subjective norms only predicted purchase intention. The results reflected that TRA was applicable to the intention of cross-border online shopping in a current on-line shopping context. We also discussed the practical applications and limitations of the study.

As one of the organizational behaviors that contribute to the performance of a company, we introduce 'Service-oriented organizational citizenship behavior(SOCB)'. In this study, we focus on voluntary behaviors than a formal action specified in the job description. Since Organ(1986) proposed the concept -Organizational Citizenship Behavior: OCB-, the reason that many researchers have noted OCB has been discretionary. Our purpose in this study is as follows. First, it is systematically to construct the factors affecting SOCB as a dependent variable in this study. Second, it is to test the antecedent(service orientation) and the mediating variable(service commitment). Third, our study is an attempt to understand the relationship among the variables in overall dimensions.

In this study, we used Brewster-Angle Microscope(BAM) to study on the molecular orientation of monolayer on the water surface. The behaviors of molecules on three different subphase have been observed. Reproducible $\pi$-A isotherm have been obtained only on information about phase transition by molecular area. BAM facilitates the observation of morphology by optical anisotropy and thickness in monolayer and multilayers as BAM is shown to be sensitive to anisotropy of film. Every transition was found by BAM technique, either as a dramatic change in degree of contrast or as a sudden alteration of molecular action and $\pi$-A isotherm.

We study free actions of finite nonabelian groups on 3-dimensional nilmanifolds with the first homology ${\mathbb{Z}}^2{\bigoplus}{\mathbb{Z}}_2$ which yield an orbit manifold reversing fiber orientation, up to topological conjugacy. We show that those nonabelian groups are $D_4$(the dihedral group), $Q_8$(the quaternion group), and $C_8.C_4$(the $1^{st}$ non-split extension by $C_8$ of $C_4$ acting via $C_4/C_2=C_2$).

Around the world, public access to information plays a crucial role in improving lives and facilitating development. People, technology, and information, which also represent common themes of i-Schools, are deemed relevant in adapting to these global challenges. The main purpose of this research is to identify the orientation of curriculums in LIS Schools in South Korea toward technology, information, and people for graduate schools of library and information science. This research also correlates the directions of the schools with the UN 2030 Agenda. Using the Wilson model, this study examines the orientation of courses offered. The result of classification and content analysis revealed that courses offered are leaning towards technology and information content. Courses reviewed in the light of developing knowledge and skills of information professionals to facilitate the fulfillment of global goals can make libraries more responsive to the changing times.

In two previous papers the author presented a general construction of finite, fiber- and orientation-preserving group actions on orientable Seifert manifolds. In this paper we restrict our attention to elliptic 3-manifolds. For illustration of our methods a constructive proof is given that orientation-reversing and fiber-preserving diffeomorphisms of Seifert manifolds do not exist for nonzero Euler class, in particular elliptic 3-manifolds. Each type of elliptic 3-manifold is then considered and the possible group actions that fit the given construction. This is shown to be all but a few cases that have been considered elsewhere. Finally, a presentation for the quotient space under such an action is constructed and a specific example is generated.

We show that the Liechti-Strenner's example for the closed nonorientable surface in [13] minimizes the dilatation within the class of pseudo-Anosov homeomorphisms with an orientable invariant foliation and all but the first coefficient of the characteristic polynomial of the action induced on the first cohomology nonpositive. We also show that the Liechti-Strenner's example of orientation-reversing homeomorphism for the closed orientable surface in [13] minimizes the dilatation within the class of pseudo-Anosov homeomorphisms with an orientable invariant foliation and all but the first coefficient of the characteristic polynomial p(x) of the action induced on the first cohomology nonpositive or all but the first coefficient of p(x)(x ± 1)², p(x)(x² ± 1), or p(x)(x² ± x + 1) nonpositive.

The aim of the paper is to use optimization and advanced numerical computation of a sail fiber-reinforced composite model to increase the performance of a yacht under wind action. Designing a composite-shell system against the wind is a very complex problem, which only in the last two decades has been approached by advanced modeling, optimization and computer fluid dynamics (CFDs) based methods. A sail is a tensile structure hoisted on the rig of a yacht, inflated by wind pressure. Our objective is the multiple criteria optimization of a sail, the engine of a yacht, in order to obtain the maximum thrust force for a given load distribution. We will compute the best possible yarn thickness orientation and distribution in order to minimize the total fiber volume with some displacement constraints and in order to leave the most uniform stress distribution over the whole structure. In this paper our attention will be focused on computer simulation, modeling and optimization of a sail-shape mathematical model in different regatta and wind conditions, with the purpose of improving maneuverability and speed made good.

In this article, we will characterize structures of geometric quotient orbifolds of G-manifold of genus two where G is a finite group of orientation preserving diffeomorphisms using the idea of handlebody orbifolds. By using the characterization, we will deduce the candidates of possible non-hyperbolic geometric quotient orbifolds case by case using W. Dunbar's work. In addition, if the G-manifold is compact, closed and the quotient orbifold's geometry is hyperbolic then we can show that the fundamental group of the quotient orbifold cannot be in the class D.

Objectives: We used participatory mapping as a tool for empowerment training for promoting health and safety of farmers. We would like to introduce the application of participatory mapping method and report our experiences in a rural community in Korea. Methods: A one-day workshop was offered in six rural villages which were designated as 'safe farm zones'. Each workshop started with an orientation session, followed by a village rounding, presentations of best cases, a group exercise to draw and present a healthy village map. Participants were requested to express their ideas and experiences about healthy and safe residential and working environments on their map. Results: A total of 206 farmers(100 male, 106 female) participated in the workshops. In each workshop, an average of 34.3 farmers participated, and their mean age was 59 years. In the six workshops, the participants proposed a total of 137 action plans. The action plans included improvement of co-working condition, building facilities for recreation, improving traffic safety measures, and improving residential environment. Conclusions: Participatory mapping was successfully developed and applied as a tool for empowering Korean farmers. The participants were able to express their ideas and thoughts about healthy and safe village and action plans on the map. Moreover, some of the actions in the action plans were carried out immediately after workshop.
