System on Panel (SOP) can integrate many functions by Thin Film Transistor (TFT) circuits on an insulator substrate without using external driver LSIs. However, to make practical SOP has become more and more difficult because of rapid cost reduction of the driver LSIs. This paper will review the circuit design technology trend for SOP and introduce an example of a practical SOP, 2.0inch QVGA full color active matrix OLED with 8bit source driver.

We have studied on response time of the fringe-field switching (FFS) TFT-LCD using the LCs with negative dielectric anisotropy related to rubbing angle. Simulation and experimental results shows that when a rubbing angle approached $45^{\circ}$, a slope of voltage-dependent curve is decreased such that the operation voltage is increased, however the whole response characteristic between inter-gray levels have a trend to be fast.

In recent years, flexible e-paper displays based on electrophorectic materials continue to attract enormous interest from technologists and are expected to be in the market soon. To realize a flexible e-paper, several key technologies for TFT backplane have been developed, while it still lacks good color reproduction and requires input function for use in its various applications. Thus, the technical issues for implementing color and touch functions in a flexible e-paper are discussed, and then our development status along with technology trend of it is described.

The field of construction and transportation R&D has been increased and improved wih the integration into the ICT. With the rapid trend changes like the Fourth Industrial Revolution, new direction and solution of R&D policy is being explored to prepare for the convergence era with other diverse research areas. In order to present new direction, it is necessary to analyze the external environment influencing construction and transportation field. In this regard, this study analyzes the science and technology policy plan and goal in Korea. In conclusion, through the policy analysis, this study suggests new direction of construction and transportation R&D in Korea.

Trend of R&D expenditure in Korea during the last 10 years, the R&D expenditure has been constantly increasing at an average rate of 10%. The government R&D ekpenditures or subsidies are increasing rapidly But the studies of evaluating impact of government R&D subsidies are few. This study attempts to empirically investigate the effects of government R&D subsidies on private firm's R&D investment in Korean industry by using Propensity score matching method which sign as to whether the relationship between government subsidies and private R&D investments is on stimulating or displacing private R&D expenditures. Empirically, a firm with government R&D subsidy are 733 million dollar more expenditure then don't receive any government R&D funding. Also Government R&D subsidies greatly increase (statistically significant) company financed R&D expenditures only for large firms but had no effect on the R&D expenditures of small & medium sized firms and venture firms.

This study analyzed keywords for agricultural R&D using the textmining method to examine the trend of agricultural R&D. Data used for the analysis included R&D project information provided by NTIS, and the research and development step by year from 2003 to 2018 were classified and applied. The TF-IDF approach was used as the analysis method, and ranking was derived based on score. Furthermore, we analyzed by grouping for similar keywords. The main analysis results are as follows. First, agricultural R&D trends are changing according to the introduction of new technologies and changes in the external environment. Second, keyword changes appeared with a time lag in the R&D step. The main keywords are changing in the order of basic research - applied research - development research. Third, the main keyword of agricultural R&D was 'rice.' However, the direction and purpose of the research were changing according to changes in the domestic and foreign agricultural environments.

Due to the development of modern technology and the enlargement of industrial scale, the scale of many projects is expanding and the complexity is also increasing. Individual management of existing projects cannot effectively manage projects in this trend, and it is necessary to systematically manage the entire process from initiation to completion. Accordingly, the need for integrated management and life cycle management that can efficiently manage the entire project is emerging, and for this, a systematic project management system is also required. PMS enables efficient project management by linking business processes such as resource, schedule, scope, and output management of a project with separately separated infrastructure accordingly. In this paper, a research model was proposed to manage the project from the perspective of implementing integrated management and life cycle management, especially during R&D project execution, and to prove the mediating role between PMS and R&D project performance for this purpose. The proposed research model will be able to help companies and organizations that feel the need to implement integrated management and life cycle management and are preparing to build a PMS-type system or that have already been established to efficiently perform project management.

Food security and its sovereignty have become among the most important key issues due to changes in the international situation. Regarding these issues, many countries now give attention to smart agriculture, which would increase production efficiency through a data-based system. The Korean government also has attempted to promote smart agriculture by 1) implementing the agri-food ICT (information and communications technology) policy, and 2) increasing the R&D budget by more than double in recent years. However, its endeavors only centered on large-scale farms which a number of domestic farmers rarely utilized in their farming. To promote smart agriculture more effectively, we diagnosed the government R&D trends of smart agriculture based on NTIS (National Science and Technology Information Service) data. We identified the research trends for each R&D period by analyzing three pieces of information: the regional information, research actor, and topic. Based on these findings, we could suggest systematic R&D directions and implications.

In order to implement nano-level accuracy of precision equipments, a nano control system is one of the key components. The control system consists of a controller, actuators and sensors having nano-level resolution. In this paper, application area and technical trend on the nano control system are introduced. Some required techniques for realizing nano-level resolution of a controller or actuator are presented. Technical innovation of a control system by IT-fusion and its effect are also described. Finally, domestic research activities for development of the IT-based nano control system are introduced.
