        Korea is a chronic agricultural importer with low self-sufficiency in food and grain. The scale of agricultural production and the number of farm workers are decreasing continuously. Korea is expected to be forced to fully open its agricultural market as it loses its status as a developing country in the agricultural sector within the WTO. Despite the agricultural slowdown and the food security weakness, the obligation to contribute to the international community has been highlighted in proportion to the level of economic development, which has failed to actively discuss and prepare for the nation"s policy to strengthen food security. South Korea, however, needs to recognize the instability of food security and diversify its policies to strengthen food security along with continued interest at the national level. This study looks at the status of domestic and foreign responses to food security, as well as understanding the concept of food security, and what are the problems related to Korea"s food security. In particular, it argues that Korea"s food security situation is not good and its policy response is not satisfactory in light of the cases of China and Japan, which have high agricultural (industrial) and economic interdependencies with Korea. Of course, South Korea has pushed for or discussed various efforts to strengthen food security, including setting and managing targets for food self-sufficiency and grain self-sufficiency, promoting overseas agricultural development projects, establishing a grain procurement system and enacting related laws. Nevertheless, in Korea, food security issues are not treated as a core policy at the national level, as they are discussed intermittently before and after the collapse of the world grain market, and the parties to the discussion are also very limited. This study reviews Korea"s food security situation and its policy alternatives from the perspective of food (or grain) self-sufficiency, self-reliance, and self-suppliance capacity (emergency response) and presents an innovative policy based on agricultural science and technology that can positively be linked those policy alternatives for food security in Korea. The followings are the policy alternatives based on the agricultural science and technology innovation to strengthen Korea"s food security. First, it is necessary to establish a national food security emergency response system from the perspective of self-suppliance capacity (emergency response). Since food security should be recognized and prepared at the system level, the national food security emergency response system should be established as a constant response system based on the enactment of relevant laws. The system consists of the International Grain Early Warning System, the National Food Crisis Diagnosis System, the National Food Security Organization and the danger-level manual (food emergency production and space utilization). Here, the R&D and list-up of crops for emergency production are based on the innovation policy in the agricultural science and technology. Second, the promotion of international (research) cooperation in agriculture is necessary to strengthen the self-reliance level. The government should link international cooperation in the agricultural science and technology, as well as rural development, with international aid policies, and promote the advance of Korean agriculture into North Korea. Finally, the efficiency of investment in agriculture R&D should be strengthened to raise self-sufficiency. This means reexamining investment strategies related to agricultural R&D targets, purposes and subjects, and adjusting them to the purpose of strengthening food security.

      • 지역 산업기술지형의 변화 양태와 시사점

        As a result of pursuing regional industrial policies based on balanced and specialized development, there is no contradiction in the positive aspects of the expansion of local industry and innovation bases. But others have questioned the effectiveness and validity of the policies. In the context of the demand for re-establishing regional industrial policies or re-establishing the direction, it is necessary to thoroughly examine and reflect on various points of view in order to prevent distortions in policy evaluation and lead to careful decisions. Therefore, this study analyzes the structure of regional technical knowledges represented by patents in a multifaceted way, especially related to the regional industrial policies. This is intended to escape from the old point of view to evaluate regional industrial policies with quantitative economic indicators such as sales, employment and production. This study utilizes patents as a representative indicator for observing regional industrial technology topography. Based on analyzing the linkage, transformation and network between IPC(International Patent Classification) and KSIC(Korean Standard Industrial Classification), This study examine the relationship between industrial technology topography and strategic industries in case regions. The case regions are Jeollabuk-do and Gangwon-do. The data utilized are registered patents from 2000 to 2016. Chapter 2 examines literature on regional innovation system, regional industrial policy and patent-based regional industrial technology topography. Chapter 3 outlines the process and status of regional industrial policies. Chapter 4 and 5, which correspond to the core analysis part of this study, deal with the analysis of three parts on the changing patterns of industrial technology topography in Jeollabuk-do and Gangwon-do, respectively. More specifically, three parts are as follows. ① The structure and connection characteristics of the regional technical knowledge structure. ② Major trends in regional technical knowledge structure change. ③ the characteristics of industrial linkages and element technology linkages. Chapter 6 diagnose the relevance between regional technical knowledge bases and strategic industries. Finally, chapter 7 suggests comprehensive conclusions and policy implications. This study found that it is reasonable to accept that regional industrial policies in Korea for about 20 years have produced positive effects on regional industrial and innovative capacity establishment. Of course, it can be denied from the old point of view to evaluate regional industrial policies with quantitative economic indicators. But we have to examine the meaning, value and effects of regional industrial policies in various aspects, before evaluating, re-establishing, sustaining or abolishing the policies. In this sense, the study presents a qualitative analysis and policy implications from different angle different from the major economic or quantitative ones. In short, despite the limitation of study that should be improved in the future, this study provides some meaningful results and suggestions for the regional industrial policy. Of course, this study is a pilot one to evaluate, diagnose, discuss the meaning, value, effects of existing regional industrial policy in Korea. The key contribution is the positioning of strategic industries of case regions to a two-dimensional matrix, consisted of an industrial policy aspect axis and a science & technology policy aspect axis. As a result, we suggest that strategic directions of regional industrial policy should be different according to the characteristics of strategic industries, regional industrial bases and technical knowledge ones. To obtain more effective conclusions, subsequent studies are needed.

        We are facing economic and social crises due to the low-growth global economy, the New Normal, the worsening struggle for hegemony between the US and China, accelerating climate change, and prolonged COVID-19. How to recognize, prepare for, and utilize crises is critical to future growth. Therefore, in this study, the perspective of ‘growth’ is reviewed and growth strategies are sought. This study is divided into two main categories. First, it explores and proposes growth engines (industry and technology) considering existing growth engines (market competitiveness, technological competitiveness, job creation effects, investment conditions) and environmental, social, and governance (ESG) perspectives, and finally A plan for fostering growth engines was proposed. Second, the current status and problems of organizational issues (promotion system) as an implementation basis for the stable implementation of growth engine policies and legal system issues (promotional legislation) as a basis for implementation were reviewed, and improvement measures were suggested. Chapter 1 introduced the background and necessity of the study, the purpose of the study, and the structure and method of the study. In Chapter 2, the preceding literature on crisis and growth and domestic and foreign policy trends were reviewed. In Chapter 3, the ‘Green Economy’, ‘Digital Economy’ and ‘Bio Economy’ were divided into promising growth engines (industry, technology) candidates for each economy, and a survey was conducted on related experts. Through the survey results, a promising growth engine for each module was finally proposed. Chapter 4 analyzed the growth issues (current status, issues, etc.) for each module, and suggested policy nurturing plans for each growth engine in terms of technology, industry (company), legal system, and manpower. Chapter 5 dealt with organizational and legal system issues separately from the final proposed individual growth engines. Chapter 6 draws general conclusions and implications.

        A novel one-body dual laser profile based vibration compensation in 3D scanning

        Lim, Yongseok,Choi, Woong,Park, Yongju,Oh, Sangwook,Kim, Younghun,Park, Jongsun Elsevier 2018 MEASUREMENT -LONDON- Vol.130 No.-

        <P><B>Abstract</B></P> <P>Recently, the 3D laser profile scanner has often been used for the precise measurement of 3D surface information (object surface) such as height, area, and slope. However, a difficulty encountered with the conventional laser scanning method is that it cannot compensate for the errors resulting from vibration, so the scanned object should be measured in a fixed (immobile) state. In this paper, we propose a novel dual laser profile method and its error compensation algorithm to compensate for vertical vibration, even with a moving object. In order to remove errors caused by vibration, the proposed system projects two laser profiles onto the surface, such that the projected position overlaps the one with the previous position. With the overlapped position, the height difference between the measured objects is used to calculate the vibration errors. To generate two laser profiles simultaneously, we present a novel approach for generating two laser profiles from one laser-emitting source (a one-body dual line laser using a triangular structured blazed grating reflector). By exploiting the one-body dual line laser and error compensation algorithm, the proposed 3D laser profile scanner system achieves an error reduction of about 96.3% in the root mean square error (RMSE), compared to the conventional approach.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Overlapping two laser profiles with time difference allows vibration compensation. </LI> <LI> One laser source generates two precise laser profiles using grating structure. </LI> <LI> Global compensation algorithm corrects error from superimposing two laser profiles. </LI> </UL> </P>

        The existing standard for soil erosion risk assessment has limitations in sustainable topsoil management since the fixed criteria are applied to determination of soil erosion risk areas regardless of land use types. It may not be necessary to apply soil erosion best management practices to agricultural areas with high potential of soil erosion because human or economic damage derived from soil erosion might be tiny in that region. Furthermore, the fixed criterion with absolute values can select too many hot spots of soil erosion to conduct efficient soil erosion management. Thus, objective of this study was to suggest the relative criteria using statistical analysis for efficient soil erosion management. In future, the relative indices for soil erosion prevention should be improved to provide a priority of soil erosion management considering economic damage from soil erosion or functional values of soil with quantitative soil erosion. Additional researches will be needed to reflect a regional characteristics and to consider various land use types and different criteria.

        대면적 대상물 변위계측을 위한 스테레오 카메라 3차원 DIC 시스템 기초설계 및 검증에 관한 연구

        고영훈 ( Younghun Ko ),서승환 ( Seunghwan Seo ),임현성 ( Hyunsung Lim ),김태렬 ( Tailie Jin ),정문경 ( Moonkyung Chung ) 대한화약발파공학회 2020 화약발파 Vol.38 No.2

        이미지 영상 상관법(DIC)은 대상물의 변위, 변형을 측정하기 위해 잘 확립된 방법이라 할 수 있다. 스테레오 카메라를 이용한 3차원 DIC 시스템은 기계산업 분야에서 재료의 변형 등을 측정하기 위해서 개발된 방법이다. 3차원 DIC 시스템을 지반 및 구조물의 변위측정 등을 위해 적용하는 부분에서의 문제는 대상물의 면적이 매우 크다는 것이 중요한 해결사항이다. DIC 알고리즘에는 대상 영역(FOV)에 대한 스케일링 기능이 있지만, 단일 카메라 시스템으로는 높은 정밀도의 시스템을 구현할 수 없다. 본 연구에서는 설정 대상물 면적(30m×20m)에서 0.5mm의 z변위 정밀도로 측정 할 수 있는 3차원 DIC 시스템의 스테레오 비전 조건을 실험을 통하여 제시하였다. Digital Image Correlation is a well-established method for displacements, strains and shape measurements of engineering objects. Stereo-camera 3D Digital Image Correlation (3D-DIC) systems have been developed to match the specific requirements for measurements posed by material and mechanical industries. Although DIC method provides the capabilities of scaling a field-of-view(FOV), dimensions of Geotechnical structure objects in many cases are too big to be measured with DIC based on a single camera pair. It can be the most important issue with applying 3D DIC to the measurement of Geotechnical structures. In this paper, We were present stereo vision conditions in a 3D DIC system that can be measured for large FOV(30X20m) and high precisions(z-displacement 0.5mm) of the ground objects with Stereo-camera DIC systems.
