Attempts are being made to use the sand dam as an alternative water resource securement facility by installing and operating sand dams in valleys, where water intake capacity is extremely limited, in areas with limited water supply in the upstream watershed of Korea. In the case of some countries in Africa, where sand dams are known to be most actively installed and used, it is difficult to find examples of establishing and applying a separate legal system for sand dams. A sand dam is a kind of groundwater dam, and in view of its concept, structural and technical form and characteristics, purpose, use, and function, it will be said that it has the legal character and status as a facility for securing groundwater resources specified in the current 「Ground Water Act」. Interpretation and application of regulations on facilities for securing groundwater resources also supports this. Therefore, it is legal and realistic to promote and implement the sand dam project as one of the installation and management projects for securing underground water resources based on the 「Ground Water Act」.

It is major strategy for SMEs to cooperate with other companies or Public Research Institutes(PRIs) as the essential technology is getting more complicated and technological life cycle is getting short. However, It is not easy to perform a proper cooperation with SMEs for PRIs, because they are accustomed to support SMEs in the short run. In addition, previous studies also have mainly focussed on finding determinants of performance as a consequence of temporary cooperation instead of long-term relationships among companies. Therefore this study analyzed which satisfaction is more effective to maintain the long-term cooperative relationship between PRIs and SMEs. As a result, it has found that when SMEs satisfy from quality of input like manpower supports R&D and context of the support program over the output like technological or economical performance, they intend to continue cooperation with PRIs. And this paper shows that the performance has mediated effect rather direct effect on long-term cooperation intention. In light of all the above, to cooperate with SMEs effectively, it will be suggested that PRIs enhance quality of support process and contents instead of quantity of support based on one-time cooperation.

Previous studies have been conducted on domestic materials as a single extract. Research on complex mixtures for maximizing plant characteristics by individual extraction and potential interference with effects is insufficient. Therefore, this study confirmed the GC-MSD according to the extraction of essential oils for Agastache rugosa O. Kuntze(AR), Pinus densiflora Sieb. et Zuccarini(PD), Curcuma longa, Curcuma domestica(CC), Zingiber officinale Roscoe(ZR), Foeniculum vulgare Miller(FV), and Citrus medica L. var. sarcodactylis Swingle(CS). The cytotoxicity, antioxidant, and anti-inflammatory properties of the blending oil were confirmed to confirm its potential as a cosmetic material. As a result of analyzing GC-MSD aroma components, the main components were estragole of AR, à-Pinene for PD, Zingiberene for CC and ZR, Anethole from FV, and D-Limonene for CS. At a concentration of 100 uL/mL with no confirmed cytotoxicity, NO production was inhibited by 70.62%, DPPH radical scavenging activity was 64.03%, and ABTS radical scavenging activity was 89.55%. Through this, blended essential oil suggests the possibility of useful application as a raw material with antioxidant and anti-inflammatory effects in the cosmetic and food industries.

Recently the biometric recognition technology is intensively studied and the standardization of the technology has been highly demanded for its commercialization. Currently many blometric recognition products are being developed based on the BioAPl(Biometric Application Program-ming Interface) specification. However, the reliable testing tools (or scenarios) to evaluate performance and conformance of the products are not shown yet. In this paper, a conformance testing method is presented, which verifies a biometric recognition system to meet the requirements of the BioAPl standard. Two different testing procedures are used in the proposed method. The first procedure evaluates that each functions offered in the BioAPl specification are correctly implemented and that the functions are actually used in the system. Through the Procedure, a BSP(Biometric Service Provider) system is executed on the framework of the BioAPl functions. It requires selection of parameters and prece-dent functions that should be executed first. The second procedure evaluates the abilities of module management, handling operations and ver-ification process by the analysis of the test cases. It tests the correctness of the system operation when a testing scenario is given. The proposed testing method is applied on a fingerprint verification BSP using the sample BSP provided by the BioAPl consortium. The experimental results shows the benefits of the proposed testing method.

We found seed money to complete MVP (Minimum Viable Product) within 1.5 years after establishment, verified PMF (Product-Market Fit) within 1 year, attracted Series A investment within 2.5 years after establishment, and successfully commercialized it. It attracted Series B investment for stable growth within 1.5 years (Series B investment within 4 years from start-up). The results of the study, the division of government programs that support stage-based startup commercialization, that is, within three years and within seven years of establishment, is significant to date. Three directions are suggested for future research. First, develop indicators for monitoring startup growth stages. Second, it continuously updates the annual changes and tracks the growth stages of individual startups. Third, we discover the successful growth law of technology-based startups by applying in-depth case analysis of successful startups to the model.

This paper aims to explore the relationship between organizational competencies and performance by analysing perception survey data of R&D management agencies in Korea. The regression analysis results show the perceived performance measured by policy contribution and R&D management efficiency may be enhanced by organizational competencies such as professionalism and efficiency of R&D management specialized agencies. The paper suggests several improvement measures for strengthening professionalism of R&D management agencies in Korea. First, expertise competencies for strategic planning, management, evaluation need to be empowered in the whole process of R&D cycles. Second, in order to stabilize financial resources of R&D management specialized agencies, the existing R&D budget for Planing, Evaluation and Management should be reformed. Third, R&D management specialized agencies need setting up special organizations for managing inter-organizational collaboration with other R&D organizations. And the agencies should employ special experts in each position for strategic planning, management, evaluation, performance and commercialization. Finally, different R&D management procedures of each R&D management specialized agency need to be standardized in order to promote innovative R&D culture.

Recently, as living standards have improved, many people are becoming more interested in health, and self-training is increasing through exercise to prevent and manage pre-illness. In general, an imbalance of muscles causes asymmetry of posture, which can cause various diseases by accompanying an adjustment force, circulation action, displacement of internal organs, etc.. In this study, the development of fitness software that can be self - training among smart wears has attracted considerable attention in recent years. In this study, a technology was proposed for the commercialization of self - trainer fitness wear by a simulation through Android - based applications. Self - trainer fitness software was developed by combining a conductive polymer, fashion design, sewing, and electric and electronic technology to monitor the unbalance of the muscles during exercise and make smart wear that can calibrate the asymmetry by oneself. In particular, a polymer sensor was fabricated by deriving the optimal MWCNT concentration, and the electrode signal was collected by attaching the electrode to the optimal position, where the electrode signal line using the conductive fiber was designed and attached to collect the signal. A signal module that converts the bio-signals collected through electrical signal conversion and transmits them using Bluetooth communication was designed and manufactured. Self-trainer fitness software that can be commercialized was developed by combining noise cancellation with Android-based self-training application using a software algorithm method.

The startup ecosystem is experiencing a paradigm shift in founding due to the acceleration of digital transformation, online platform companies have grown significantly into unicorns, but the lack of differentiated approaches and strategic support for deep tech startups has led to the inactivity of the startup ecosystem. is lacking. Therefore, in this study, we proposed ways to develop domestic startup development policies, focusing on the US system, which is an advanced example overseas. Focusing on the definition and characteristics of deep tech startups, current investment status, success stories, support policies, etc., we comprehensively analyzed domestic and international literature and derived suggestions. In particular, he proposed specific ways to improve support policies for domestic deep tech startups and presented milestones for their development. Currently, the United States is significantly strengthening the role of the government in supporting deep tech startups. The US government provides direct financial support to deep tech startups, including detergent support and infrastructure support. It has also established policies to foster deep tech startups, established related institutions, and systematized support. It is worth noting that US universities play a core role in nurturing deep tech startups. Leading universities in the United States operate deep tech startup discovery and development programs, providing research and development infrastructure and technology. It also works with companies to provide co-investment and commercialization support for deep tech startups. As a result, the growth of domestic deep tech startups requires the cooperation of diverse entities such as the government, universities, companies, and private investors. The government should strengthen policy support, and universities and businesses should work together to support R&D and commercialization capabilities. Furthermore, private investors must stimulate investment in deep tech startups. Through such efforts, deep tech startups are expected to grow and Korea's innovation ecosystem will be revitalized.

The purpose of this study is to provide a common model and implementation strategies for reusing GIS components in local governments. The common model includes several solutions to remove stumbling blocks step by step in reusing or exchanging GIS application systems between local governments. Elements of the model are component architecture, common business process model, common function model, and data model. The elements are the minimum standards for reusability. In order to realize the desirable common model at present, however, the following problems remain : usable components are insufficient in spatial domains and existing GIS application systems require reinvestment to accommodate the new component technology. Three questions are raised to maximize reusability from a monolithic structure toward layered and the componentized GIS application systems : (1) How can the application systems be reused within a local government?, (2) Can the systems be exchanged when they are in the same computing platform?, and (3) When the systems are componentized by standardized interfaces, are the components replaceable between the systems in local governments? Some strategies are presented to accomplish the objectives implicated in the questions. For the actual implementation, several issues such as evaluation procedures for component products, ownership and commercialization issues, will be brought up in the future. Central and local governments, and commercial party need to co-operate each other to maximize the reusability. Reducing overlapping investments in local governments and obtaining competitive component technology in the commercial party should be recognized as critical tasks for the more efficient and economical GIS implementation.
