  • The purpose of this study is to determine whether the centralization of information technology activities and the organizational structures, especially the centralization of decision making and the complexity have any effects on the information systems performance. The strategic types, the formalization dimension of organizational structures, and the industrial characteristics, which might have impacts on the dependent variables were controlled. Information systems performance was measured by both user satisfaction and organizational performance. To achieve the research objective, a field study using the structured questionnaires was employed. Thirty large companies participated in this study. Multivariate regression analysis was used to analyze the data collected. Findings of this study are summarized as follows: The centralization of IT activities, the centralization of decision making, the complexity of organizational structure and the interaction effects among these independent variables all turned out to have statistically significant effects on the user satisfaction, while not on the organizational performance. The implication of these findings is that the IT structure must be determined in congruence with the organizational structures and vice versa. One weakness of this study is that the strategic type was not an independent variable but a controlled variable. Further study of using the strategic type as an independent variable with more sample corporations is to be encouraged.

  • Community design education has covered the worldview dimension of the collaborative courses for sustainability draws on the architectural expertise developed in a network of community projects and therefore case studies of design education by the collaborative project-based learning in terms of participants, students, teachers and architects, such as 'Learning By Design' for the K-12 comprehensive program in Massachusetts addresses how a local society can make its community sustainable by both design and education. To understand that community design and education can provide professional development in all levels of skills and knowledge across disciplines and opportunities for collaborative learning and problem-solving, this research consists of case studies of the community design education including social systems that assist in organizing the local educational program as well as promoting the programs with public awareness of the community. It covers the UNESCO-UIA agenda of the community design and education that is to enhance the physical environment relating to human interaction by developing innovative alternatives of existing community and contributing voluntarily to neighborhoods through design. As the community design collaborative of design professionals and users is a structural approach to assess design quality, the cases address how to set up the architectural program in order to share pro bono design service and provide high-quality design resources available for sustainable environment.

  • Based on the Job Demand-Control model which was proposed by R. A. Karasek, this study was designed to investigate the relationships among job demand, job control, and job burnout of nurses. In addition, the other aim of the present study was to test the moderating or buffering role of social supports in the relationship between the job demand and job burnout. The analysis based on data collected from 239 nurses who are working in two general hospitals has produced the following results. We found that job demand was primarily related to the exhaustion component of burnout, whereas (lack of) job control was related to the disengagement dimension of burnout. And social supports from the supervisor attenuated the disengagement, whereas social supports from the colleague diminished the exhaustion. But, we found no interaction effects that were expected in the hypotheses. Specifically, social supports didn't buffer the negative effects of job demand on burnout, while job control had the moderating effect which was in opposite direction. The implications of these analyses and limitations of the study were then discussed.

  • In the present study a parametric analysis is conducted to study the effect of pile dimension and soil properties on the nonlinear dynamic response of pile subjected to lateral sinusoidal load at the pile head. The study is conducted on soil-pile model of different pile diameter, pile length and soil modulus, and results are compared to get the effect. The soil-pile system is modelled using Finite element method. The programming is done in MATLAB. Time history analysis of model is done for varying non-dimensional frequency of load and the results are compared to get the non-dimensional frequency at which pile head displacement is maximum in each case. Maximum possible bending moment and soil-pile interacting forces for the dynamic excitation of the pile is also compared. When results are compared with the linear response, it is observed that non-dimensional frequency is reduced in nonlinear response on account of reduction in the soil stiffness due to yielding. Nonlinear response curve shows high amplitude as compared to linear response curve.

  • A multiscale method is presented for analysis of thin slab structures in which the microstructures can not be reduced to two-dimensional plane stress models and thus three dimensional treatment of microstructures is necessary. This method is based on the classical asymptotic expansion multiscale approach but with consideration of the special geometric characteristics of the slab structures. This is achieved via a special form of multiscale asymptotic expansion of displacement field. The expanded three dimensional displacement field only exhibits in-plane periodicity and the thickness dimension is in the global scale. Consequently by employing the multiscale asymptotic expansion approach the global macroscopic structural problem and the local microscopic unit cell problem are rationally set up. It is noted that the unit cell is subjected to the in-plane periodic boundary conditions as well as the traction free conditions on the out of plane surfaces of the unit cell. The variational formulation and finite element implementation of the unit cell problem are discussed in details. Thereafter the in-plane material response is systematically characterized via homogenization analysis of the proposed special unit cell problem for different microstructures and the reasoning of the present method is justified. Moreover the present multiscale analysis procedure is illustrated through a plane stress beam example.

  • Purpose - This research paper aims to examine the impact of entrepreneurial orientation (EO) and government support programs (GSP) on new product performance in Korean Small and Medium-sized Enterprises (SME). We specifically focus on the interaction between these two factors and their influence on the new product performance of Korean SMEs. Research design, data, and methodology - We collected survey questionnaires from SMEs that are certified with Inno-biz by the Korean Ministry of SMEs and Startups. The collected data was analyzed using SPSS 26 and AMOS to create an integrated model. Result - Based on the analysis, our findings indicate that the proactiveness and innovativeness dimensions of EO have a positive effect on new product performance. However, the risk-taking dimension of EO has a negative effect. Additionally, GSP exhibit both positive and negative moderating effects on different dimensions of EO. Conclusion - It is important to recognize that GSP are not a universal solution for all challenges faced by SMEs. Hence, it is crucial for policy-makers to have a clear understanding of SMEs' capabilities and the level of EO dimensions in order to identify types of GSP that could lead to positive outcomes, while minimizing the negative effects of GSP.

  • The purpose of this study is to investigate the effect of achromatic shirt and chromatic tie combination on image of menswear. This experiment was designed by shirt color(N9, N7, N4, N2), tie color(red, orange, yellow, green, blue, purple), tie tone(vivid, light, dull, dark), and perceiver gender(a male, a female). The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 96 upper body photographs and 26 7-point bi-polar adjectives were used to evaluate the image. The subjects of this research were 480 male and 480 female college students. The data was analyzed by using SPSS program. Analysis methods were four-way ANOVA. The items of the adjectives were classified into 4 image factor: potency, activity, attractiveness, and visibility. Shirt color, tie color, tie tone influenced on the 4 image dimension greatly by interaction as well as independently. Dull or dark tone tie had an effect on the formation of potency image. And white color shirt, vivid or light tone tie had an effect on the formation of activity image. White or black shirt had a positive effect on attractiveness, and black shirt or vivid tone tie was effective for visible image.

  • Purpose - This study examines the role of e-commerce resulting from technological innovation as a new approach toward internationalization. We study the relationship between e-commerce export and country distance, measured in CAGE distance, which has hindered traditional internationalization. As a control variable, entrepreneurship was introduced to check the moderating effect on the relationship between country distance and e-commerce export. Design/methodology - Based on empirical analysis, e-commerce exports from the Republic of Korea to 96 countries were used as dependent variables. First, hierarchical regression analysis was conducted to test the hypothesis about each country's distance, measured by CAGE distance, and each dimension of CAGE, on e-commerce exports. Next, the hypothesis was tested through the interaction term to examine the moderating effect of entrepreneurship. Findings - The analysis showed that the hypothesis, which postulated e-commerce exports as affected negatively by the country's distance, was supported but not that all CAGE dimensions affected it. Specifically, geographical distance and economic distance have negative effects, but cultural distance and administrative distance did not affect e-commerce exports. Thus, in contrast to the expectation that distance restrictions in e-commerce would not exist, this study confirmed that distance still matters to internationalization and that entrepreneurship can mitigate the adverse effects. Originality/value - Through these results, when export firms try to enter new markets and start internationalization through e-commerce, the entrepreneurship of the importing country should be considered.

  • This study was to find the difficulties students faced in their mathematical learning and to identify the instructional dimensions a teacher provided for the students from multi-cultural background. Since the study was focused on the process of students' learning, the qualitative method was chosen through clinical interviews with 2 students in a total of 11 units which played a role of compensating their learning of mathematics as an extra curriculum. The students solved the computational problems relying on formal procedure without understanding of concepts and principles and solved the word problems based on own interpretation of certain words without semantic comprehension out of math sentences. As the instructional dimensions of teaching mathematics, tasks, a tool and classroom norm were found in the activities they performed. For the tasks, situated tasks, challenging tasks, tasks with lack of conditions, and open-ended exploratory tasks were used. As the tool, pictorial representations were very useful to describe their ideas. Finally, as the classroom norm, consider equity for everyone, and cooperate and encourage each other were found.
