As science and technology infiltrates every aspects of modern society in terms of economic and social growth and development, funding for research and development (R&D) is growing rapidly. Republic of Korea is not an exception in this trend and the R&D funding in Korea has been grown about 10% every year, recently. However, as the scope and size of funding grows exponentially, need for monitoring and managing these R&D projects becoming more and more imminent. Though different types of project management systems were developed by a variety of agencies and departments and used in monitoring and managing, these systems were developed as standalone silo type systems. These systems are not connected to each other while the same researchers may involved in different projects across agencies and department. Also, these management systems are not linked to the banking systems in which real transactions of funding occurs, such as cost reimbursement and financial audit of each R&D accounts. Historically, a few fraud and malappropriation cases were found and indicted. However, as the number of these incidents grows along with the growth of R&D funding, a large scale integration/linking of project management systems and banking systems. Realizing the importance of systems integration among agencies as well as with the banking systems, situational requirements analyses were conducted concerning the current state of R&D management system. As a results, a Real-time Case Management System (RCMS) was proposed as a solution to current problems. In this paper, the collected systems requirements were documents with analyses of the situation, the architecture of the integrated systems with more user-friendly technological alternatives. This large scale linkage requires interface standardization as well as modularization of interfaces. Proposed systems architecture is introduced here with technical details of Jex Framework used,, followed by resulting technical and economic performance of the Realtime Cashflow Management System (RCMS).

In the general manufacturing sector, prototyping used to reduce the risks that can arise with new conceptual products. However, in AEC area, it does not mass-produce a building, so the prototype itself becomes a building. Therefore, it is challenging to have prototyping of the same scale as the real thing, and the prototyping process in architecture is very inefficient. The prototyping process in the design stage typically assumes making a scaled model, partial model, or digital model. However, it is difficult for these models to correspond to the actual building and the environment of time and space such as scale, material, environment, load, physical properties and deformation, corrosion, etc., unlike the actual building. When using the digital twin concept in the prototyping process, it is possible to measure performance from the design stage to the operation stage. The digital twin was found by a method for monitoring based on physical twins and real-time linkage in the operation stage. Therefore, if the digital twin concept is applied at the design stage, it is possible to predict performance using not only current performance but also history information using real-time information. In order to apply the digital twin concept to the prototyping design process, we analyze the theoretical considerations and the prototyping design process of the digital twin, analyze the cases and research results where the prototyping design was applied, Provide an applied prototyping design process. The proposed process is tested through a pilot project and analyzed for potential use.

In the past decade, there have been many advances in whole-genome sequencing in domestic animals, as well as the development of "next-generation" sequencing technologies and high-throughput genotyping platforms. Consequently, these advances have led to the creation of the high-density SNP array as a state-of-the-art tool for genetics and genomics analyses of domestic animals. The emergence and utilization of SNP arrays will have significant impacts not only on the scale, speed, and expense of SNP genotyping, but also on theoretical and applied studies of quantitative genetics, population genetics and molecular evolution. The most promising applications in agriculture could be genome-wide association studies (GWAS) and genomic selection for the improvement of economically important traits. However, some challenges still face these applications, such as incorporating linkage disequilibrium (LD) information from HapMap projects, data storage, and especially appropriate statistical analyses on the high-dimensional, structured genomics data. More efforts are still needed to make better use of the high-density SNP arrays in both academic studies and industrial applications.

Buildings are becoming more and more high-rise and large-scale in recent years, so in the event of a disaster such as a fire, enormous human and economic damage is expected. Therefore, management, security, and fire control are essential for large buildings in the city. Because these large buildings are very complex outside and inside, they need a three-dimensional control based on 3D modeling rather than a simple flat-oriented control. To do this, this paper designed and implemented a building control system based on 3D modeling. Specifically, we designed a 3D building / facility editing module for 3D modeling of buildings, a 3D based control module for building control, and a linkage module that connects information such as firefighting equipment, electrical equipment and IoT equipment. Based on this design, a building control system based on 3D modeling was implemented.

We review the research literature on relationship between environmental regulation and industrial development in three aspects of environmental regulation and investment, environmental regulation and efficiency, environmental regulation and trade. Indeed, the linkage between environmental regulation and material consumption of industrial system is absent. Environmental regulation is measured as the expenditure share for industrial pollutants abatement, and effluent charge intensity. Using panel-level data from 31 provinces, municipalities and autonomous regions in China, we build correlation models between material consumption and environmental regulation, results show that: (1) there are significant quadratic function relationship between material consumption and environmental regulation. And there is the fact that inflection point exists. (2) On basis of inflection points, we make two remarkable reflections. Firstly, the inflection points are the most important scale to judge reasonability and performance of regulations. Secondly, a Pareto improvement may occur when the regulations achieve a certain target. (3) Both intensities of industrial pollutants abatement expenditure and effluent charge have not yet achieved the expected target in most regions of mainland China at present. And most of regions of material consumption decreasing are distributed in western China. Main reasons lie in the impacts of industrial features as well as the regulations.

Vortex-induced oscillation is a type of aeroelastic phenomenon, to which extended structures such as long-span bridges are most susceptible. The vortex-induced vibration (VIV) behaviors of a concerned bridge were investigated conventionally in virtue of wind tunnel tests on string-mounted sectional models. This necessitates the building of a linkage between the response of the sectional model and that of the prototype structure. Although many released literatures have related to this issue and provided suggestions, there is a lack of consistency among them. In this study, some theoretical models describing the vortex-induced structural motion, including the linear empirical model, the nonlinear empirical model and the modified (or generalized) nonlinear empirical model, are firstly reviewed. Then, the concept of equivalent mass density is introduced based on the principle that an equal input of energy should result in identical structural amplitudes. Based on these, the theoretical linkages between the amplitude of a section model and that corresponding to the prototype bridge are discussed with different analytical models. Theoretical derivation indicates that such connections are dependent mainly on two factors, one is the presupposed shape of deformation, and the other is the theoretical VIV model employed. The theoretical analysis in this study shows that, in comparison to the nonlinear empirical models, the linear one can result in obvious larger estimations of the full bridges' responses, especially in cases of cable-stayed bridges.

For the vibration control of residential buildings, a multiple type slim damper system is developed and dynamic performance test is performed in this study. In conventional damping systems, larger installation space is required in order to achieve acceptable seismic performance, and as a result, it is difficult to determine efficient damping capacity of the device. The proposed damping device is composed of several small slim type dampers and linkage units. It can control damping capacity easily by changing the number of the small damper. To evaluate the proposed damping device, three slim type dampers (single-type, triple-type and penta-type) are designed and manufactured in real scale. Dynamic loading tests are performed by using the three manufactured dampers. From the tests, it is shown that damping coefficient is proportional to the number of the damper combined. Thus, test results validates the practicality of the proposed slim type dampers. applying nonlinear curve fitting technique, numerical model of the dampers are developed and presented.

The objectives of the study are to identify the issues and problems encountered in Korea's current integrated rural regional development(IRRD) program and to suggest policy remedies to cope with them. Secondary data and materials ate mainly used for the study. Since the mid-1980s, rural settlement planning has been carried out in the Republic of Korea, In the planning process,'scale of economy'perspectives and settlement policy have been emphasized for increasing the efficiency of investment. During the 1990s, rural settlement and major village development projects have been implemented under the rural structure transformation programs. Agricultural structure adjustment projects for land consolidation and sizable farming have been separated from the rural settlement and mojor village development projects. Based on the evaluative analysis for the rural structure transformation policy and program, some problematic issues were raised as follows: (a) lack of integrative control function in the program'(b) weak linkage between living environment improvement and agricultural development projects: and (c) lack of comprehensive village development planning and implementation system. The policy issues to solve the problems were suggested as follows: (a) adoption of bottom-up approach in new IRRD planning and project system : (b) projection of comprehensive development planning and project at the village level; and (c) introduction of new regional agriculture development projects such as direct payment system for farming in less favorable areas and organic farming.
