  • New knowledge is created through the dynamic interaction of knowledge that depends largely on a social context within the organization. Social processes influence the nature of knowledge and learning. This paper is rooted in the concept of social capital. Social capital theory emphasizes the importance of social relationship. Using social capital theory, this paper suggests three factors that must be satisfied for the development of knowledge combinative capability. The first factor is that the opportunity exists to make the exchange or combination of knowledge. The second factor is that people is motivated for the creation of new knowledge. The third factor is that people must share the common knowledge. This paper examines the change case of KIPO (Korean Intellectual Property Office). This case provides evidence that the three factors can develop social relationship, and build knowledge combinative capability. The man finding from this research is that social factors play an important part in the creation of knowledge, and processes of knowledge exchange and combination heavily rely upon social patterns, practices and processes in ways which emphasize the value and importance of collective action and knowledge sharing. This research may have several implications for the development of the knowledge creation mechanisms.

  • Terzaghi's tunnel pressure theory is generally used to estimate primary design pressures on tunnel support for shield and urban NATM tunnels until now. A trial is made in this paper to investigate the interaction between the ground deformation behavior and Terzaghi's tunnel pressure, which assumes pound's limit (or critical) state, by considering results of 'Terzaghi's tunnel pressure theory. two-dimensional reduced-scale model tunnel tests and nonlinear numerical analysis based on strain softening modeling. A full understanding between tunnel pressure and ground deformation behavior under the tunnel excavation and an effective utilization of this interaction lead to an economical tunnel support design and a safe construction of tunnel.

  • This is qualitative research using grounded theory to examine the experiences that mothers of children with epilepsy can have. Data were collected through in-depth interviews, observation, and memo-taking with a total of 13 participants in this study-10 mothers taking care of children with epilepsy and 3 principal informants-and the data were analyzed using the method developed by Strauss and Corbin (1998). As a result of data analysis, 163 concepts, 26 subcategories and 8 categories were formed through open coding. Such categories were analyzed by the paradigm of the grounded theory, and as a result the experiences of the mothers of epileptic children were based on a causal condition of 'confrontation' and the central phenomenon of 'Wandering around the forest under a yoke'. The contextual conditions, which exerted influence on phenomena, were 'stigma cognition', 'personality traits' and 'health of children.' The action/interaction strategy selected by participants was 'Quietly pulling through: Bracing myself, Getting to know my enemy and myself, Taking care while hiding, Putting out one step at a time, Establishing a foothold. The intervening condition affecting action/interaction was 'the support system', and its result was 'watching.'

  • An asymptotic local plane strain elasticity theory is reformulated for the static analysis of a simply-supported, multiple graphene sheet system (MGSS) in cylindrical bending and resting on an elastic medium. The dimension of the MGSS in the y direction is considered to be much greater than those in the x and z directions, such that all the field variables are considered to be independent of the y coordinate. Eringen's nonlocal constitutive relations are used to account for the small length scale effects in the formulation examining the static behavior of the MGSS. The interaction between the MGSS and its surrounding foundation is modelled as a Winkler foundation with the parameter kw, and the interaction between adjacent graphene sheets (GSs) is considered using another Winkler model with the parameter cw. A parametric study with regard to some effects on the static behavior of the MGSS resting on an elastic medium is undertaken, such as the aspect ratio, the number of the GSs, the stiffness of the medium between the adjacent layers and that of the surrounding medium of the MGSS, and the nonlocal parameter.

  • The very definitions of posture and balance have changed, as has our understanding of the underlying neural mechanisms, In rehabilitation science, there awe at least two different conceptual theories to describe the neural control of posture and balance : the reflex/hierarchical theory and system theory. A reflex/hierarchical theory suggests the posture and balance result from hierarchically organized reflex responses triggered by independent sensory systems. The systems approach suggests that action emerges from an interaction of the individual with the task and environment. That is to say, the systems approach implies that the ability to control our body's position in space emerges from a complex interaction of musculoskeletal and neural systems, collectively referred to as the postural control system. The specific organization of postural systems determined both by the functional task and the environment in which it is being performed, The postural control system is divided into three basic functional components for assessment : 1) musculoskeletal components, 2) motor coordination components, and 3) sensory organization components. It is proposed that a systemic functional understanding of human balance is critical to effective programs for balance rehabilitation. Thus, this article briefly reviews the basic functional components to consider in designing treatment plan and for the benefit of the balance assessment.

  • This study presents a conceptual framework for the growth process as a manager based on data gathered from the sales experiences and careers of fashion brand managers. The study participants were seven managers with over 15 years of sales experience in a women's clothing brand in Gwangju. Data were collected through in-depth interviews from January 2018 to September 2018 and analyzed using open coding, axis coding, and selective coding according to Strauss and Corbin's grounded theory method. The study results are as follows. First, this study found six categories and 17 sub-categories based on the shop manager's sales experiences and careers. Second, we found the central job category as well as categories with causality, interaction, moderating and outcome relationships. Third, we developed a paradigm model that links the main phenomena, causal conditions, contextual conditions, intervening conditions, action/interaction strategies, and consequence categories. Fourth, the process of growing as a fashion brand manager was described by an integrated story.

  • This study analyzes the role of market actors in the energy transition process and the interaction between them and ordinary citizens, primarily focusing on the mini-PV project in Seoul. The study also proposes measures to harness market actors' activities and successfully implement the distribution of mini-PV systems in Seoul. In this study, practice theory is used as a theoretical resource to analyze the interaction between market actors and civil society actors and to help understand how market actors influence the decisions of regular citizens in installing mini-PV at their properties. After conducting surveys and hosting in-depth interviews with ordinary citizens and market actors, it was found that to further promote the role of market actors, the Seoul Metropolitan Government should actively support and monitor the public relations activities of market actors, while concurrently managing selected companies and establishing relevant administrative systems for continued effective use post-installation of mini-PV systems. In future studies of the energy transition process, market actors should also be recognized as key players, along with government and civil society actors, and their roles should be studied in a balanced way.

  • This study aimed to identify a difference in project implementation between villages that had executed rural village community activation support work successfully and those that had quit in the middle from the new endogenous development theory perspective. As a result, it was found that the main factors used for promoting to increase endogeneous development capabilities existed more in villages that executed project implementation support work successfully than in villages that had quit in the middle. Successful villages have a difference from the villages that had quit in the middle in that they have established a participatory decision making and cooperation system for stable operation even before their support work began, they have more assets for promoting community activity, residents' interaction and communal activity are becoming more active, and reciprocity-based mutual aid culture exists in many forms. In conclusion, seeing from the new endogenous development theory perspective, villages are developed under the interaction between internal and external factors, but the outcome of project implementation depends on whether village community holds its endogenous development capability to operate and develop such whole process of development. Therefore, village community activation policies need to be reinforced in the direction toward promoting to create the main factors for enhancing endogenous development capabilities.

  • Electromagnetic interference (EMI) is defined as the interaction phenomena of electromagnetic waves scattered from a large structure or complex terrain. In this study, the propagation of linear wave is modeled with ray theory, direct simulation Monte Carlo (DSMC), and some classical theories on flat plates. The wave physics of reflection, refraction, and diffraction are simulated for the investigation of front and back scattering of the one-dimensional plane wave from a tower with ray theory and DSMC, respectively. The effect of rotating disk idealized from the real wind-turbine blades is modeled with a simplified version of the classical electromagnetic theory as well as DSMC based on the ray theory.

  • This paper presents the method of numerical analysis concerned with the hydropdynamic forces and moments of the floating bodies exerted by waves. The analytic methods of hydrodynamic wave forces and moments for large volume structures are generally classified into four categories ; the strip method, the boundary element method, the finite element method, and the potential matching method. In the case of the comparatively large structures, diffraction theory can be applied. However, there are no application limits of diffraction theory which have been known concerning with the analytic method of the rectangular structures. In this paper, the two-dimensional B.E.M. is treated for a moored small rectangular structure in order to evaluate applicability of diffraction theory. Numerical calculation is carried out for the structure. The results are compared with some other ones for verification. The result shows that diffraction theory is applicable to structures smaller than 0.15 in the ratio of the representative structure length d to wave length L for rectangular ones.
