As every commentators has noted, bureaucratic corruption, which has complicated causes, is prevalent phenomenon in Korean society. Especially, most people realize that systemic corruption has a strong negative effect on society; however, only few studies reflect on the nature of 'systemic corruption' and it seems that no established theory explains the phenomenon. Thus, this study suggest that we look more carefully into the nature and mechanisms of 'systemic corruption'. Interdisciplinary approach based on the integrated model of structure-behavior to analyse the nature of bureaucratic corruption. The system dynamics method can test the mechanisms of 'systemic corruption'. With this way, the factors generating systemic corruption represent the relationships reinforcing and balancing within system dynamics model. This paper also consider 'isomorphism' and 'dominance' as control mechanisms to systemic corruption. From the CLD(Causal Loop Diagram), three main areas(rent in organization, networking, control mechanisms) are overlapped and it indicates dynamic relationships of systemic corruption in organizations.

Exhaust system of car is studied by thermal analysis. Temperature is uniformly distributed from $22{^{\circ}C}$ to $200{^{\circ}C}$ on exhaust system due to heat transfer. The largest deformation of 2.6919mm is shown at the left end of muffler. The inner face combined with exhaust manifold is applied by the largest thermal equivalent stress of 914.61MPa. After the elapsed time of 360 second, the end of muffler is shown to have the largest deformation of 2.5538mm and the bolt combined with this muffler is applied by the largest equivalent stress of 887.79MPa. By reinforcing material at the end of muffler or fastened bolt shown with highest thermal deformation or stress, the durability at this system can be improved.

Korea is examining how to coordinate its S&T policies and solidify its position as a leader of infrastructure innovation policy that forms the foundation for many different policies. A number of questions have been raised, such as whether to install a superior coordinating body like the National Science and Technology Council (NSTC) or separate the budget allocation and coordination authority from the budget-planning ministry. Korea has tried using various institutional coordination devices and functions such as reorganizing its administrative ministries based on related functions and installing or reinforcing a superior coordinating body. In line with these discussions, the strengthening of the S&T policy coordination function through the NSTC is currently under review. In order to design an effective S&T coordination system in step with changing political and social demands, it is important to have a clear recognition of the current context as well as the unique institutional characteristics of Korea. This study examines the evolution of Korea's S&T policy coordination systems and analyzes its features.

The purpose of the present study lies in understanding the historical context as well as regulatory and administrative restraints of records and archival management system of Korea, with the case of Korean Government Archives and Records Service(GARS). Insights gained from the historical analysis of GARS are expected to provide strategies to develop and reinvent GARS so that the national agency could be the basis of reforming Korean archival system in the future. The present study firstly reviews historical context of 1960s and 1970s, during which GARS was established, as well as its role and hierarchical standing in Korean administrative system. Second, its organizational system is analyzed, focusing on the extent of its specialization and organizational independence. Third, the study proposes to develop strategies to reinvent GARS through reinforcing the public records and archives management act(1999).

To overcome the common deficiencies found in such two-way slabs, such as excessive cracking around columns, excessive deflections and low punching shear strength, it was proposed to investigate the strategic reinforcing steel distribution detailings. Concentration of the top mat of flexural reinforcement result in a higher punching shear resistance, higher post cracking stiffness, a more uniform distribution of strains in the top bars and smaller cracks at all levels of loading.

In this study, the carbody design of the rubber tired AGT(Automated Guide-way Transit System) under development by KRRI was numerically analysed to evaluate its structural strength according to the standard specifications for Korean LRT (Light Rail Transit). The numerical results showed that the detail design of the carbody was strong enough to satisfy the specifications with respect to the axial compression strength, the vertical strength and the vertical stiffness(natural frequency). However, the carbody design had some problems on the fatigue strength by twist loadings. So, it was recommended that the carbody design should be modified to improve the twisting strength by reinforcing the front end structures.

Recently, geogrid reinforcement has been applied tn the subgrade of the roadway and the railway on the compressible layered soil, and the relevant reserch on the reinforcing mechanism has been performed. In this study, mechanics of geogrid reinforcement and the parameters for the improvement of bearing capacity are evaluated and presented based on the case histories of the field load test on the geogrid-reinforced layered subgrade

Owing to these mechanical properties, carbon nanotubes have the potential to be employed in many future devices and nanostructured materials. As an example, high Young modulus accompanied by their low density, makes them a good choice for reinforcing material in composites. Therefore, we empathize and manually derive the results which shows the utilized lemma and criterion are believed effective and efficient for aircraft structural analysis of composite and nonlinear scenarios. To be fair, the experiment by numerical computation and calculations were explained the perfectness of the methodology we provided in the research.

Technological systems are defined as network(s) consisting of technological infrastructure, industrial organization, and institutional infrastructure. This paper reviews SEMATECH in the U.S. and VLSI Program in Korea as a technological system for semiconductor, which is an advanced technology. Several issues are addressed : how did they get started\ulcorner ; how have they been evolved\ulcorner ; how have the actors and institutions within the system interacted\ulcorner ; what role has the government played in that process\ulcorner Both systems were created by their government, respectively, and they have been evaluated as successful. However, while SEMATECH became complete eough in terms of technological infrastructure, industrial organization, and institutional infrastructure to generate sufficient increasing returns to develop in a self-reinforcing way, a series of VLSI program in Korea is still operated discontinuously under the government subsidy. SEMATECH is more flexible and stable than Korea's VLSI program in that the system has a centralized structure and has been managed and staffed by industry substantially. In addition, both cases show that a technological system may evolve having connections with foreign technological systems and local sub-systems beyond nations, regions and industries. Many other similarities, contrasts, and insights for technological policy from each country's experiences are presented.

The numerical formulation of a two-phase interface element appropriate for porous lining system is presented. The formulation is isoparametric and can be applied both for 2-D and 3-D analysis. Biot's theory is utilized as the basis for the development of the element constitutive theory. In order to be capable of simulating the reinforcing characteristics of some geotextiles utilized as lining system, a reinforcement component has also been implemented into the formulation. By employing this specially developed interface finite element, the influence of soil consolidation on the stress distribution along the lining system of a reservoir and a landfill has been investigated.
