  • As the global semiconductor supply chain falters, major countries are pushing to increase their self-sufficiency in semiconductors. In accordance with these global changes, R&D cooperation is evolving in the semiconductor industry. Previously, as for the case of Interuniversity Microelectronics Center (IMEC) in Europe, many cooperation initiatives were established regardless of nationality for improving productivity through measures such as reducing the time and cost required for joint research. Recently, however, cooperation aimed at strengthening one's own industry has been prominent, such as that led by Taiwan Semiconductor Research Institute (TSRI) and the United States National Semiconductor Technology Center (NSTC). Hence, the Korean semiconductor industry also needs to respond. Internally, technology localization should be promoted by strengthening the foundation for domestic R&D cooperation, while externally, it should expand close cooperation with companies from countries leading the semiconductor industry, such as the United States, Europe, and Japan.

  • The paper examined Southeast Asia as a whole and focused on similarities among countries composing what is now known as the Association of Southeast Asian Nations (ASEAN). In order to determine these similarities, the analysis focused on the fact that during World War II the whole of Southeast Asia was occupied by one political power: Japan. The policies the Japanese implemented in the region were to a degree very similar in terms of pressures and tensions that occurred in the different countries. The paper argues that these pressures and the responses of the various peoples of Southeast Asia instilled a nucleus of common identity in Southeast Asia as a whole. Basically, the policies that the Japanese implemented all over Southeast Asia were the following: the setting up regional administrations; the extraction of resources and emphasis on local self-sufficiency; the implementation of cultural Japanization; and local indigenization policies. The Southeast Asian responses that crystalized this joint Southeast Asian identity may be described as: accommodating and resisting the Japanese; commemorating portraying; and collectively remembering the era. The process of action and reaction between Japan and Southeast Asia was formative of this joint Southeast Asian identity.

  • The Helium cooled ceramic reflector(HCCR) test blanket module(TBM) has been designed and developed to participate the ITER(International Thermonuclear Experimental Reactor) test blanket program in Korea. The TBM was one of the main objectives for developing ITER for proving the tritium self-sufficiency and the heat transfers to produce the electricity with the breeding blanket concept. Among the TBM components, the first wall(FW) was the most important component in safety since it was directly faced a high level of a heat and fast neutrons from the plasma side and could protect the others components inside TBM. In this paper, the FW has been designed through the thermo-mechanical analysis considering ITER operation conditions. With the developed simple models, the stress limit analysis based on RCC-MR code which is the nuclear power plant design codes in France was evaluated for the allowable design criteria. The results showed that the designed FW model satisfied $1.5S_m$ or $3S_m$ of the allowable stress($S_m$) in RCC-MR code at the maximum stress region in the FW.

  • Food policy is considered as the most basic and central issue for all countries, while making efforts to keep each country's food sovereignty and enhance food self-sufficiency. In the case of Korea where the staple food is rice, the rice yield prediction is regarded as a very important task to cope with unstable food supply at a national level. In this study, Korean paddy Rice yield Prediction Model (KRPM) developed to predict the paddy rice yield using meteorological element and MODIS NDVI. A multiple linear regression analysis was carried out by using the NDVI extracted from satellite image. Six meteorological elements include average temperature; maximum temperature; minimum temperature; rainfall; accumulated rainfall and duration of sunshine. Concerning the evaluation for the applicability of the KRPM, the accuracy assessment was carried out through correlation analysis between predicted and provided data by the National Statistical Office of paddy rice yield in 2011. The 2011 predicted yield of paddy rice by KRPM was 505 kg/10a at whole country level and 487 kg/10a by agroclimatic zones using stepwise regression while the predicted value by KOrea Statistical Information Service was 532 kg/10a. The characteristics of changes in paddy rice yield according to NDVI and other meteorological elements were well reflected by the KRPM.

  • The design of the blanket and shield play a key role in determining the size of a reactor since it has an impact on the various reactor components. The blanket should produce enough tritium for tritium self-sufficiency and the shield should provide sufficient protection for the superconducting TF coil. Neutronic optimization of the blanket and the shield is necessary, and we coupled the system analysis with a neutronic calculation to account for the interrelation of the blanket and shield with the plasma performance of a reactor system in a self-consistent manner. By using the coupled system analysis code, the operational space for a low aspect ratio (LAR) tokamak reactor with a superconducting toroidal field (TF) coil is investigated with an spect ratio in the range of 1.5 - 2.5. The minimum major radius which satisfies all the physics and engineering requirements increases with the magnetic field at the magnetic axis. A required inboard shield thickness is mainly determined by the requirement on the protection of the TF coil against radiation damage. It is shown that to have a fusion power bigger than 3,000 MW in the LAR tokamak with a superconducting TF coil, a major radius bigger than 4.0 m is required.

  • Purpose: Evidence-based design is the process of making design decisions based on reliable research to achieve the best results, so it is important to accumulate reliable evidence through research. Therefore, the purpose of this study is to present new evidence by applying the evidence-based design process to improve the digital signage for each room spaces in hospitals and verifying its effectiveness. Method: Through the 8-step process of evidence-based design, improved digital signage for each room spaces are installed. It conducted surveys and statistical analysis to prove hypotheses by linking design and research. Results: The hypotheses established in the study are: 1) improvement in the readability of digital signage is correlated with patient satisfaction; 2) Improving the intuitiveness of digital signage correlates with patient satisfaction; 3) Improving the sufficiency of digital signage correlates with patient satisfaction. As a result of satisfaction analysis and correlation analysis, all of the above hypotheses were proven. Implications: Although the hospital sign system is the element that patients rely on most intuitively in the long journey of reception, waiting, examination, and treatment, there is insufficient evidence to refer to or apply it when designing. It is necessary to expand future research to expand the evidence that can be applied to hospital sign design.

  • The food self-sufficiency rate of agricultural products in Korea, excluding rice, is around 20%, and the government is promoting various policies including a Multiple-Purpose Utilization of Paddy Fields project, to increase the self-sufficiency rate of major grains. The project for Multiple-Purpose Utilization of Paddy Fields is being promoted as a part of a program to create farmland infrastructure to facilitate the cultivation of crops other than rice in rice paddies, and pilot projects were started in four regions in 2020. The purpose of this study is to analyze the economic effects of the pilot project for Multiple-Purpose Utilization of Paddy Fields, and to propose policies to increase the effectiveness of the project. In order to analyze the economic effect, we estimated the change in farm income generated by switching from rice to other crops, and measured the effect of welfare change using the Equilibrium Displacement Model (EDM). As a result of the analysis, social welfare is expected to increase when the pilot project for Multiple-Purpose Utilization of Paddy Fields is implemented, and the income of the beneficiary farmers is also expected to improve compared to that of single-cropping when double-cropping is implemented. However, it was found that the economic feasibility of the project differs depending on the crops converted. Juksan-myeon, Gimje-si, which is an area where soybean production was successful, was analyzed from the viewpoint of increasing the economic feasibility of the pilot project. Their success factors were analyzed into four major factors: infrastructure, farming methods, education, and collaboration with local agricultural organizations. If such a success story can be utilized in the future project implementation process, it can contribute to the improvement of farm household income and national economic welfare.

  • Wheat is one of the most important crops in production and consumption. Despite increasing of importance, the self-sufficiency of wheat is less than 2% in Korea. To improve yield potential and broaden the genetic pool of common wheat in Korea, introduction of alien germplasms into the Korean wheat breeding program is suggested. For effective utilization of the germplasm, we introduced total 1,195 germplasms from the world, which were provided by National Plant Germplasm System (NPGS, USDA) and evaluated the yield, field performances and agronomic traits for 8 years. Among 55 countries, germplasms from Canada, Ethiopia, Mexico and United States accounts for 78%, especially germplasms collected from United States accounts for 50%. Yield comparison of germplasms and collected region analysis indicate that the high yielding germplasms are collected from countries or states of particular range of latitude. The combination analysis of the yield and agronomic traits and the geographical information of collected region will be utilized for improving Korean wheat breeding programs.
