Algorithms from the research of the layout migration were proposed in the paper. These are automatic recognition algorithm for the VLSI devices from it, graph based construction algorithm to maintain the constraints, dependencies, and design rule between the devices, and high speed compaction algorithm to reduce size of the VLSI area and reuse the design with compacted size for the new technology. Also, this paper describes that why proposed algorithms are essential for the era of the SoC (System on a Chip), design reuse, and IP DB, which are the big concerns in these days. In addition to introduce our algorithms, the benchmark showed that our performance is superior by 27 times faster than that of the commercial one, and has better efficiency by 3 times in disk usage.

The control surveying which aims at identifying the coordinate system of satellite images with that of ground is a repeatedly performed essential process to produce digital ortho - photos and it acts as the main factor to increase the production cost of the photos by duplicated budgets and redundant works when executing the projects for acquiring basic geographical information from high density satellite images. During the experimentation, an application system was established for producing a stereo image chip by the analysis of DPPDB file structure, the stereo image chip was produced with SPOT and IKONOS images, the analysis of 3D modeling accuracy was performed to secure the required accuracy and to present the optimal number and deployment of the control points, and a 3D modeling was performed for new SPOT images and lastly, 3D ground coordinates were extracted by the observation of the same points through the overlapping with the new images. As the results of the research, it is proved that the stereo image chip can be used as the ground controls through the accuracy analysis between the coordinates of the images and the ground, close results were obtained between the coordinates by the ground survey and those by the 3D modeling using new images and the observation of the same points, positional changes were not found during observing the same points, and the research presented the methodology for improving the process of the control survey by showing the availability of the image controls on the stereo image chip instead of the ground controls.

Family companies are the unique industry-academic cooperation-related systems of Korean universities created by universities to promote various forms of industry-academic cooperation with companies. It is important to figure out the current status of family companies in order to understand the achievements of industrial-academic cooperation projects that have been actively pursued since the early 2000s. A lot of studies on industry-academic cooperation have focused mainly on the university's position. On the contrary, this study focuses on understanding the current status of the family company system and the status of industry-academic cooperation. Introduced in 2004, the Family Company System expanded rapidly as it was used as a performance indicator for college financial support projects related to industry-academic cooperation, with 174,425 companies registered as family companies as of 2017. A survey of family companies registered in universities carrying out the LINC+ project shows that companies registered in multiple universities are increasing, with relatively high demand and satisfaction for industry-academic cooperation among companies. Family companies were found to be relatively satisfied in terms of the use of R&D equipment or joint research, while they were relatively less satisfied in terms of workforce training and retraining. While companies have assessed product quality improvements through industry-academic cooperation, they have underestimated the effect of increasing sales and reducing production costs. Further, it was found that it was urgent to expand incentive systems and improve online information services to boost corporate participation in order to enhance the effectiveness of industry-academic cooperation.

The purposes of the study were to; 1) examine the diffusion and adoption of new agricultural technology in rice farming, 2) survey the status of agricultural education institutions on technology transfer, and 3) explore the linkages between agricultural education and extension for more effective reinforcement strategies to further the diffusion and adoption of new agricultural technology in Korea. Literature review, field survey and panel discussions were employed to strengthen the linkages among agricultural education, research and extension in Korea. As the results of analysis of the diffusion and adoption of new agricultural technology in rice farming following recommendations were offered; 1. Extension services have helped Korean farmers in achieving self-sufficiency in rice and year-round supply of green vegetables as well as upbringing rural youth, however, government changed the status of extension educators from central government staff to county/city government staff since 1997. This brought about various problems such as: decreased morale and number of extension educators, thus weakening the extension education function, weakened linkages between national and local extension offices, less opportunity for in-service education of extension educators, and weakened linkages between agricultural research and extension, etc. 2. In order to insure that extension educators are high caliber professional individuals, it is crucial to establish a system that nationally recognizes these individuals as such, and that provides a professional development path. It is important to restore the morale of extension educators to continually achieve the national goals of food production, balanced national development and preservation of environment, at the same time to meet increasing needs of farmers. 3. Because of the critical importance of diffusing innovations to agricultural producers in order to ensure quality and steady food supply, it is crucial that these issues be addressed before the extension service further deteriorates. Further research activities on agricultural extension should be conducted for more effective agricultural extension system in Korea to achieve a greater rural, national and regional development. 4. Research and implementation activities should be emphasized and encouraged to improve the cooperation and collaboration among agricultural education research and extension to better serve farmers' educational and information needs. National level research activities should be encouraged to improve the effectiveness of agricultural technology transfer including internet education programs for farmers in Korea.

With massive and dense production, the livestock industry is rapidly moving into a large-scale, capital-intensive industry especially in swine, poultry, and ducks. However, livestock epidemics can pose a serious threat to the livestock industry and the lives of the people. The government has established and operates the National Animal Protection and Prevention System (KAHIS) since 2013 in order to control the threat, in accordance with the five stages. The digitalized data and information are excellent in ease of management, but it is also pointed out that it is difficult to take countermeasures through linkage with the data in an emergency situation. Recently, the technology of the fourth industrial revolution such as Internet of Things (IoT), Big Data, Artificial intelligence (AI) has been rapidly implemented to the livestock industry, which makes smart livestock disease control system possible. Therefore, this study investigated the domestic and overseas cases which apply 4th Industrial Revolution technology in the industry, and derived 13 possible candidate tasks in the near future. In order to ascertain the priority of policy formulation, we surveyed the expert groups and examined the priority of each of the five stages of the prevention and the priority of each stage. The results of this study are expected to contribute to the establishment of policies for the advancement of smart livestock disease control research and livestock protection.

In South Korea, there is a growing domestic need for a biotope map which contains ecological and environmental geographic information of a city. After the production of a Urban Ecological Maps(biotope map) by the Seoul metropolitan government in 2000, Natural Environment Conservation Act was revised in 2017 to make it mandatory for a local government to draw up its own urban ecological map. The aim of the present study was to find out ways to utilize an urban ecological map as a mean of communication between natural environment planning and urban planning sectors in a preliminary stage before introducing a big framework of 'environmental and ecological planning.' The northern area of Incheon metropolitan city was selected as the target area for this study. The major research content includes a comparative analysis of special-purpose zones, urban planning zones, restricted development zones, and conservation forests with focus on biotope types and Grades 1 of 'Biotope Type Assessment.' Farmland biotopes and forest biotopes within an area designated as an urban zone (residential, commercial and industrial zones) need to be redesignated as a zone which can conserve them. Especially considering a high possibility of damage to a large scale of natural green areas, these areas need to be readjusted immediately. If the entire area designated as an urban planning zone is to be developed, it is likely to cause serious damage to natural biotopes in the area (56.2%), including farmland biotope (30.4%), forest biotope (15.0%) and grassland biotope (10.8%), and thus, readjustment is needed. In case of a conservation forest, as it can possibly be damaged by the designation of special-purpose zones, it is necessary to match the designation of conservation forests or a special-purpose zones with their biotope types. In conclusion, we present a variety of thematic maps for utilization of an urban ecological map and propose a phase-specific environmental and ecological plan. Phase 1 is the establishment of a urban plan in consideration of ecological status; Phase 2 is the independent establishment of an environmental and ecological plan by an environment department; Phase 3 is an integrated management of ecological planning system and urban planning system.

Due to the impact of COVID-19, untact performances where performance videos are recorded, edited and distributed have begun to be activated in a non-face-to-face environment. Performance halls are supporting untact performance services such as video production and broadcasting so that performances can be viewed through online platforms. Therefore, this study intends to study the satisfaction and continued use intention of the untact performance service in the concert hall for experts who have experience using the untact performance service in the concert hall. A total of 9 hypotheses were rejected and 10 hypotheses were adopted as a result of developing and analyzing a research model suitable for the untact performance service of the concert hall by fusion of the information system success model and the expectation inconsistency model. Excluding content quality, it was found that in both system quality and service quality, inconsistency occurs through the comparison of expectations and performance after expectations arise. This positive discrepancy affects satisfaction, and the higher the satisfaction, the higher the intention to continue using it. This study is a basic study on the untact performance service and is expected to provide a new perspective for quality improvement.

This study aimed at analyzing the educational needs of home economics teachers for food literacy cultivation education in secondary school home economics. A total of 192 home economics teachers were surveyed about their perceptions of importance and performance of food literacy education content categories and elements, and their priorities were identified. Among the 38 content elements presented, home economics teachers recognized that the current performance level was significantly lower than that of the importance over 34 content elements. Based on the Borich educational needs assessment and the Locus for Focus Model, we identified five content elements with 'very high' educational needs ('food security/food sovereignty', 'reducing food-related waste', 'food waste management and recycling', 'food-related waste recycling', and 'country of origin information'), and four content elements with 'high' educational needs ('genetically modified food', 'ethical food consumption', 'food additives', and 'eco-friendly agricultural products'). These results indicate that dietary education in secondary school home economics should emphasize both the production and disposal of food. The findings of this study suggest implications for the needs for a new dietary education in secondary school home economics that allows students to learn all stages of food system. These results can also be used as a basis for dietary education for cultivating food literacy in secondary school home economics education.
