We investigated electro-optic and ionic properties of twisted nematic cells by using control of chiral pitch. These properties are observed in practical experiment and simulations. C-V and V-T curve characteristics were obtained from three types of cells with d/p. It is shown that d/p ratio of short cells exhibit faster response time improved by 20% than normal cell. Also, inter-gray response time is improved each rise time and decay time. And, the increase of saturation voltage is happened because of the small twist angel change from initial state at high voltage near 5V. To compensate for longer black level tail, gamma curve index was varied from g = 2.2 to g = 2.7 in module status. Additionally, adding chiral dopant into TN cells improved ionic characteristics such as increasing VHR, Ion density and DC Hysteresis were decreased..

The survey of research and development (R&D) in science and technology (S&T) covers the current status of R&D activities in S&T in Korea, and provides a basis for decision making regarding S&T policy. Continuous improvement of the survey is widely needed to present reliable national basic statistics. Therefore, the purpose of the study is two-fold: to introduce sampling survey method in industrial sector and to make statistical technique to deal with non-response data from industrial sector. To these ends, first, case studies of the United States and Japan are illustrated. A new sampling design for the R&D survey is proposed and implementing stratified random sampling scheme is suggested. Moreover, statistical analysis of the non-response data is dealt with. Based on several screening criteria, we develop a new imputation method suitable for the R&D survey and also provide more detailed implementation plan. Various solutions to a problem arising from non-response item are also presented. Finally, some implications of the results are discussed.

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.

Recently, various Ni doping systems and thermal annealing systems have been developed for fabrication of polycrystalline silicon film using SGS (super grain silicon) for medium and largesize AMOLED panels. In this study, we compare the potential of Ni doping systems including ALD (atomic layer deposition), AMD (atmospheric metal deposition), in-line sputter, and crystallization annealing systems including batch type furnace, inline furnace, and RTA (rapid thermal annealing) developed for the SGS method. Additional requirements for those systems to be used for mass production of large AMOLED TVs are suggested based on evaluation results for both poly-Si films and TFT backplanes.

In recent years, there has been a gradual increase in the number of R&D projects for solving societal problems. However, government-funded research institutes(GRIs) are going through many trials and errors due to the lack of R&D systems suitable for solving societal problems. In this regard, this study attempted to discuss the improvement directions for evaluation systems of GRIs, which serves as a major influencing factor in performing R&D initiatives for solving societal problems. Towards this end, a study of R&D initiatives for solving societal problems was conducted first, and improvement directions for effective promotion were presented after deriving limits in terms of R&D initiatives for solving societal problems, along with the current status of evaluation systems by GRIs. Lastly, implications and limitations of this study were discussed. This study has its significance in that it is the first research to propose evaluation indicators in terms of solving societal problems at the level of GRIs and is expected to be a foundation for future research of related fields.

With the rise of the metaverse industry worldwide, relevant national strategies and nurturing systems have been prepared in Korea. As the complexity of policies increases, the importance of establishing data-based policymkaing is growing, and studies diagnosing national R&D trends in the metaverse field are still lacking. Therefore, this paper collected NTIS national R&D information for 9,651 R&D projects promoted from 2002 to 2020. And this study looked at the current status and identified major topics based on the topic modeling, and considered time-series changes in the topics. Eleven major topics of R&D tasks in the metaverse field were derived, hot topics were service/content/platform development and medical/surgical fields of application fields, and cold topics were urban/environment/spatial information fields. Strategic R&D Management, metaverse-related laws, and institutional studies were proposed as policy directions.

This paper aims to measure and analyze R&D productivities and efficiencies of 17 major OECD countries including Korea over the 1984-2008 period by using the Malmquist Productivity Index and Data Envelopment Analysis, classifying R&D performance into an output and outcome aspects. It also searches the Korea's current status and characteristics in each R&D stage to enhance Total Factor Productivity (TFP) compared with other developed countries. Our major findings are the followings: (i) Korea's productivity index of R&D input vis-a-vis R&D output is very high (13.39% annual growth rate) compared with those of major advanced countries, whereas the annual average of efficiency index is very low (0.33), i.e. Korea's technical efficiency index has risen to 0.83 at the last time series started at 0.10 point and come up to the level of major advanced countries. (ii) the Korea's productivity index of R&D output vis-a-vis R&D outcome is very low (14.02% annual reduction rate) compared with those of major advanced countries, whereas the annual average of efficiency index is very high (0.22), i.e. Korea's integrated frontier technical efficiency index has dropped to 0.057 at the last time series started at 1.00 point and coming up to the level of major advanced countries. (iii) The productivity of R&D input vis-a-vis R&D outcome is positively correlated with that of R&D output vis-a-vis R&D outcome and the growth of R&D input factors. In a nutshell, it implicates that the effort to take advantage of R&D outputs, namely establishing the diffusion and commercialization system of technical knowledge to the level of developed countries, should be strengthened over that on the growth of R&D investment and output for enhancing R&D productivity and efficiency in Korea.

This study suggested the necessity of the management of R & D management records produced from government-supported science research institutes (the so-called "gwagichulyeon") and of a record management manual (item). As such, it gathered rules with regard to record management, conducted a survey, and interviewed general R & D managers. As a result of the research, the ratio of the arrangement of R & D managers to R & D management departments is 100%; however, the ratio of the arrangement of record managers is 33.3%-50%, and the ratio of the arrangement of record management departments is 23.1%, which was poor. The enactment ratio of record management rules is 26.4%, and 73.7% of institutes has managed their records under the provision only of document management rules or only of office management rules. R & D management records has been collected according to an institute's capability without a prescribed collection scope, and the conditions with regard to the omission, damage, and loss of records were poor. There are institutes that did not comprehend the production status of R & D management records. Thus, as a response, this study suggested a record management manual (item) established for the arrangement duties of record managers and record management departments as well as for notifications on the status of R & D management records. In addition, this study produced a standardized collection scope and described how to manage R & D management records.
