In this paper an improved one-dimensional frame element for modelling of reinforced concrete beams and columns subjected to impact is presented. The model is developed in the framework of a flexibility fibre element formulation that ignores the shear effect at material level. However, a simple shear cap is introduced at section level to take account of possible shear failure. The effect of strain rate at the fibre level is taken into account by using the dynamic increase factor (DIF) concept for steel and concrete. The capability of the formulation for estimating the element response history is demonstrated by some numerical examples and it is shown that the developed 1D element has the potential to be used for dynamic analysis of large framed structures subjected to impact of air blast and rigid objects.

Purpose - The purpose of this study is to explore and examine the effects of airline deregulation in the United States and South Korea as a comparative analysis. The study focuses on identifying the purposes of airline deregulation and analyzing its benefits and consequences. Research Design, Data, and Methodology - This is a case study, a comparative method, which analyzes and measures the benefits and disadvantages of airline deregulation in both the United States and South Korea. Results - Airline deregulation removed unnecessary and ineffective government controls, resulting in more efficient airline industries in both countries. However, the negative consequences are much greater than the benefits of airline deregulation. Conclusion - The purpose of airline deregulation was to foster an efficient and effective environment in airline industry, and clear evidence of the positive intended effects of airline deregulation e.g., increasing domestic competition, decreasing airfare, increasing productivity, and removing unnecessary government regulations in the beginning of airline deregulation. However, the current state of airline industry in both countries depicts only the consequences of airline deregulation.

This report describes the inception, development and extensive use over 30 years of elliptical polarimeters at the University of Pennsylvania. The initial Mark I polarimeter design utilized oriented retarder plates and a calcite Foster-Clarke prism as the analyzer. The Mark I polarimeter was used on the Kitt Peak 0.9 m in 1969-70 to accomplish a survey of approximately 70 objects before the device was relocated to the 0.72 m reflector at the Flower and Cook Observatory. Successive generations of automation and improvements included the early-80's optical redesign to utilize a photoelastic modulated wave plate and an Ithaco lock-in amplifier-the photoelastic modulating polarimeter. The final design in 2000 concluded with a fully remote operable device. The legacy of the polarimetric programs includes studies of close binaries, pulsating hot stars, and luminous late-type variables.

A novel flexibility-based 1D element that captures the material nonlinearity and second order P-$\Delta$ effects within a reinforced concrete frame member is developed. The formulation is developed for 2D planar frames in the modified fiber element framework but can readily be extended to 3D cases. The nonlinear behavior of concrete including cracking and crushing is taken into account through a modified hypo-elastic model. A parabolic and a constant shear stress distribution are used at section level to couple the normal and tangential tractions at material level. The lack of objectivity due to softening of concrete is addressed and objectivity of the response at the material level is attained by using a technique derived from the crack band approach. Finally the efficiency and accuracy of the formulation is compared with experimental results and is demonstrated by some numerical examples.

In this paper, I investigate the impact of quality management activities on the public sector within the framework of Malcolm Baldrige (MB) national qualify model. The Structural Equation Modeling approach has been employed to investigate the cross influences among the seven MB categories. This empirical study shows that a number of statistical hypotheses are significant. The leadership category is the most important driver among the quality management activities. This, in turn, implies that the main source in quality management is to foster a solid qualify oriented leadership system. Categories such as Information Analysis, Strategic Planning, Human Resource Development and Management, and Process Management are significantly related to the Customer Satisfaction category. In addition, leadership, Information Analysis, and Customer Satisfaction categories ere significantly influential to Management Performance.

The Korean government amended the Environmental Technology and Industry Support Act to foster the environment industry and support the advancement of domestic environmental companies into overseas markets. The amended act reflects changes in the government's policies on environment related issues. This paper uses outcomes of research conducted on environmental policies in foreign countries and the current status of the domestic environment industry to present long-term strategic plans and measures to support the expansion of environmental companies into the global markets and to vitalize the environment industry at home. The suggestions for assisting domestic companies in making inroads into overseas markets are as follows: building up and expanding cooperative network; fostering promising companies and exports by making the right choices and focuses; diversification of export markets and strengthening supports for development of new customers; promoting supports for winning overseas projects; and developing cooperative projects to respond to climate change in developing countries using the Global Climate Fund (GCF).

Our gorvernment announced an educational reformation bill to establish the institutional foundation of educational system on May 31, in 1995. To secure the open education which is to foster students' creativity, individualization and personalization, it was requested that the past teacher-centered system should be changed to learner-centered system. To gurantee such a change, however, there are many conditions that has to be satisfied first. I think that the most important thing for the new system is a close interaction between teachers and students. To accomplish a successful interaction, the teachers' understanding and attitude toward their students must change at first. The purpose of this study is to examine what kind of understanding and attitude the teachers need, and what kind of roles teachers must take charge of. At the same time, I suggest that we need to establish a Teacher Center to give teachers a seperate place to learn new theories, and to exchange among themselves the informations they got from the actual field experience.

Fifth-generation (5G) wireless communication supports low latency of up to 1 ms or less, 20 Gbps of data rate, and more than 1 million connections. With these technical advantages, machines and equipment can be precisely adjusted, allowing 5G to be applied to industrial applications. To expand the industrial application of 5G wireless communications, major countries have introduced dedicated 5G, allowing specific companies to build and use 5G directly. Germany, UK, and Japan allocate 100 MHz, 416 MHz, and 1,200 MHz, respectively, of bandwidth dedicated to 5G. Companies with local licenses from the government are expected to accelerate the application of 5G at a low cost and low-frequency range. Therefore, Korea should introduce private 5G to foster 5G-related industrial ecosystems and successfully implement the fourth industrial revolution.
