Purpose - This study investigated the effect of consumers' personal characteristics on their attitude toward social commerce focusing on the theory of reasoned action. Specifically, consumers' personal characteristics were further classified into personal characteristics, personal values concerning social commerce consumption, and consumption emotion concerning social commerce. Research Design, Data, and Methodology - The study investigated the relationship among consumers' personal characteristics, and the personal values of affirmative beliefs and attitudes of individuals toward social commerce based on the theory of reasoned action. A total of 151copies question nairewere evaluated, after excluding 13 copies having poor answers. Results - Consumers' personal characteristics were found to have a significant positive effect on their attitude toward social commerce. In addition, the most important personal characteristic affecting consumers' attitude toward social commerce was utilitarian value. Consumers' personal values were found to have a significant positive moderating effect between shopping value (i.e., hedonic and utilitarian values) and their attitude toward social commerce. Conclusion - The findings suggest that consumers' attitudes when trading with social commerce are affected by utilitarian value, and that companies should increase consumers' shopping value and build positive value about social commerce itself.

Jeong Si-Han(1625-1707), one of the main representatives of Toegye School in The mid-Korea Dynasty, seeking to live in seclusion of his life engaged in research work, respected by scholars for generations. He, Together with Yi Hyeon Il(1627-1704), carried out a systematic study of Toekye's Interpretation of the "Four Buddings" and "Seven Feelings". In this paper, from a comparative point of view, The author studied Jung Sihan's Li-Qi Theory, Four-Seven Theory, Human Mind and Mind of the Dao. Although his theory of interpretation about Li-Qi Theory, Four-Seven Theory, is the tendency of compromise Toegye and Yulgok's thought, but from the master and servant and upper and lower relationship between Li-Qi and Four-Seven Theory, Jung Sihan preferred the thought of Toegye. The characteristics of Human Mind and Mind of the Dao is Emphasis on Zhu Xi's theory about human mind of "is-to-be"

The purpose of this study is to explore the possibility of qualitative evaluation and applicable models in the evaluation area of educational program. To this end, the concept and characteristics of qualitative evaluation are examined, and grounded theory is selected as a suitable methodology for evaluation, and its characteristics and procedures are described. Because qualitative evaluation focuses on the spontaneous practice elements of the site, it can supplement the quantitative evaluation of the variables set in advance. The researcher presented the theory of qualification as a methodology for qualitative evaluation, aiming to extract the theory explaining the phenomenon among the qualitative methodologies.

In this work, dynamic behavior of functionally graded (FG) porous nano-beams is studied based on nonlocal nth-order shear deformation theory which takes into the effect of shear deformation without considering shear correction factors. It has been observed that during the manufacture of "functionally graded materials" (FGMs), micro-voids and porosities can occur inside the material. Thus, in this work, the investigation of the dynamic analysis of FG beams taking into account the influence of these imperfections is established. Material characteristics of the FG beam are supposed to be vary continuously within thickness direction according to a "power-law scheme" which is modified to approximate material characteristics for considering the influence of porosities. A comparative study with the known results in the literature confirms the accuracy and efficiency of the current nonlocal nth-order shear deformation theory.

The diffusion of the pollutants released into atmosphere is dependent on its chemical reaction, topography and micrometeorological characteristics. The purpose of the study is to investigate how much micrometeorological characteristics such as stability, wind speed and mixing height affect the diffusion of the air pollutants. For this purpose, this paper let 1) the basic theory be K-theory, 2) eddy diffusivity and wind speed be dependent on mixing height and stability, and 3) Grout method be used for numeric calculation. The result was 1) the more unstable condition, the higher mixing height and the higher wind speed we, the lower pollutants concentration appears, 2) the most intensive effect on the distribution of the pollutant concentration is the atmospheric stability.

In this paper, the flow characteristics of an axial fan spraying isothermal compact jet in a confined space were investigated by the experimental methods, the numerical method, and the free jet theory According to the results, the numerical result and the experimental result are agreed well qualitatively and different quantitatively within $\pm1.0%$ for the centerline velocity, the entrainment ratio, and the maximum throw. However, the free jet theory can reasonably predict the centerline velocity except the entrainment ratio and the maximum throw. In other words, the entrainment ratio and the maximum throw by 1.he free jet theory are hard to estimate the characteristics of jet because of restriction of c confined space.

The effect of static preload on the dynamic properties of rubber materials is rather important, especially when good isolation characteristics are required at high frequencies. However, there are still few papers for dynamic characteristics of compressed rubber components. It was demonstrated in reference (4) that for bonded rubber material of a cylindrical shape, a simplified theory equation between linear dynamic and nonlinear static behavior of rubber material was useful to predict their combined effects. This paper presents the second part of the study. It is confirmed that for the compressed rubber material, the stress can be factored into a function of frequency and a function of strain(stretch). The finite element methodis applied to analyze non-linear large deformation of rubber material and its results are compared with those of a simplified theory equation. The predicted dynamic material properties based on non-linear static finite element analyses have a good agreement of experimental results and those based on simplified theory equation.

Although aspiration towards quality of life and holistic health has been growing faster in our modern society and the affordance of health in built environment has been more acknowledged, there has been hardly any development on built environment planning and design theory that can be comfortably and confidently used in creating built environment to promote holistic health. Thereby, this study sets out to experimently formulate a composite theory that explains the relationship between health and built environment. The main methodology of this study is literature review and analysis. Theories that have been applied in other similar fields were chosen to be analyzed by health related perspectives and graft those theories onto holistic health viewpoints to compose a comprehensive theory. Selected theories that were considered useful to be analyzed were Lawton's Environment Press Theory, Carp & Carp's Complementary & Congruence Theory, Valins' Activity-based Design Criteria Theory, Atchley's Continuity Theory, Murtha & Lee's User Benefit Criteria Theory, and Alexander's Pattern Language Theory. Characteristics of these theories were compared by their abstractness and concreteness, and the range of application, and analyzed by a holistic health perspective. Then, these theories were comprehensively structuralized and synthesized as a built environment for health theory. This study has its significance in providing a base to develop healthy built environment research further as it introduced a conceptual framework which explains spatial elements in the health functionality point of view.
