While the Korean government has increased the budgetary supports on small businesses since the late 1990s, the competitiveness gap between large and small firms has been widened. This study explores various policy measures under the Roh-government, classifying them and pointing out their problems from a technological innovation perspective. Analyzing eight policies in different functional areas, such as funding, venture incubation, technology development supports, marketing supports, management consulting, information providing, labor supply and cooperation among businesses, this study finds that most of government support programs are not effective for the technological innovations of small business. It seems to be originated from short-termed policy goals and resource-input oriented policy implementation. Based upon the analyses, several policy alternatives are suggested to facilitate the technological innovations of small businesses.

Based on the survey data from 550 Korean corporate R&D centers, this study is to analyzes the patterns of industry-academy collaborations in Korean national innovation system. The analysis reveals that more than half of the corporate R&D centers involved in the collaborations with local universities and/or public R&D institutes. However, the outcomes of the collaboration are not so sufficient to improve technological capabilities of participant firms. Most of the collaborations are short-term, application oriented, small cooperative R&D projects which are not helpful for the accumulation of advanced technologies. The data also shows that the collaboration between industry-academy is quite vivid while the industry-industry collaboration is rare. These results imply the cooperative R&D activities of firms in Korea are quite dependent on the government support program and subsidy. Finally, this study proposed several policy alternatives to change Korean industry-academy collaboration system from government driven to market driven system.

Purpose - The purpose of this study was to examine the effect of government R&D programs on firm innovation activities. Design/methodology/approach - This study analyzed survey data on innovation survey in Korea. To investigate our research hypothesis we used ordered logit regression analysis. Findings - This study unveils different effects of diverse government R&D programs on firm innovation activities. Most of government programs-R&D tax incentives, information/training, and marketing supports-have positive effects on management innovation activities and negative effects of the usage of procurement programs on management innovation efforts. Some government programs-R&D tax incentives, R&D grants, information/training-have positive effects on technological innovation activities. Research implications or Originality - This paper investigates the effects of diverse government R&D programs on technological and management innovation activities. We examine simultaneous effects of multiple government R&D programs rather than effects of independent R&D programs. This result can contribute to develop more effective government R&D programs to support firm innovation activities.

Peptides exhibit lower affinity and a shorter half-life in the body than antibodies. Conversely, peptides demonstrate higher efficiency in tissue penetration and cell internalization than antibodies. Regardless of the pros and cons of peptides, they have been used as tumor-homing ligands for delivering carriers (such as nanoparticles, extracellular vesicles, and cells) and cargoes (such as cytotoxic peptides and radioisotopes) to tumors. Additionally, tumor-homing peptides have been conjugated with cargoes such as small-molecule or chemotherapeutic drugs via linkers to synthesize peptide–drug conjugates. In addition, peptides selectively bind to cell surface receptors and proteins, such as immune checkpoints, receptor kinases, and hormone receptors, subsequently blocking their biological activity or serving as hormone analogs. Furthermore, peptides internalized into cells bind to intracellular proteins and interfere with protein–protein interactions. Thus, peptides demonstrate great application potential as multifunctional players in cancer therapy.
DQ: Two approaches to measure the degree of decentralization of blockchain
이재승,Byungheon Lee,Jaeyoung Jung,심호준,김황남 한국통신학회 2021 ICT Express Vol.7 No.3
Blockchain technology innovatively removes the need for intermediaries and establishes a trust-less trust system by peer-to-peer networks and distributed ledger technology. It is still difficult to clarify the specific degree of decentralization of blockchain even though the decentralized characteristic of the system is derived from this system structure. Namely, the criteria for determining whether decentralized are not well established and do not reflect the real world well. So we propose two approaches to measure the degree of decentralization of blockchain system that currently exists: Censorship resistance and geographical diversity. This paper outlines the meaning of each decentralization quotient and explains how those indexes can be applied in respect of the user protection.

As an exploratory attempt, this study examines the patterns of strategic changes of the firms and changes in strategic group structure in response to environmental changes of the industry. Empirical analyses of 39 firms in the Korean tile industry for the period of 1986~1990 reveals that : 1) environmental changes had different impacts on attractiveness of different product/market segments : 2) the relatively large firms in less attractive product/market segments were more likely to change their domains : 3) according to their specific target product/market segments, the firms tended to strengthen different resource capabilities which were identified as key success factors to compete in each target segment : and 4) these differences in strategic changes of the firms resulted in the changes in strategic group structure during the same period. Implications and the limitations of this study are finally discussed.

AS a medical imaging technology, dual-energy computed tomography (DECT) has attracted attention owing to its higher accuracy in terms of material separation compared with conventional single-energy CT imaging. A multi-material decomposition (MMD) technique that can separate two or more materials from DECT images has recently been developed. Although a highly accurate material separation can be obtained when MMD technology is applied to CT images, the inevitable addition of noise to the image is a disadvantage. Thus, block-matching and 3D fltering (BM3D) denoising algorithm was modeled to evaluate its applicability to CT images of materials separated using MMD technology. The simulation results confrmed that when the BM3D denoising algorithm was applied to CT images separated from the material using MMD technology, the root mean square (RMS), structural similarity index, and coefcient of variation (COV) were improved by 92.44%, 16.44%, and 92.82%, respectively, compared to when only MMD was applied. In addition, the experimental results showed the same tendencies as the simulations, and volume fraction accuracy (VFA) along with the RMS and COV evaluation parameters showed the best results when BM3D was applied to CT images. Improved results were obtained using the BM3D denoising algorithm when applying the MMD technique to DECT images.
기업가정신이 창업 의도에 미치는 영향 : 창업자 성별과 나이, 창업환경의 조절 효과를 중심으로
알탄줄(ALTANZUL),이병헌(Byungheon Lee),김선영(Sun-Young Kim) 기업가정신학회 2020 기업가정신연구 Vol.1 No.2
구조적인 경기침체가 지속되면서 기술기반 창업의 중요성이 커지는 오늘날 기업가정신이 창업으로 실현되도록 하는 요인에 관한 연구가 필요하다. 본 연구는 기업가정신과 창업 의도 간에 정(+)의 관계를 밝히고, 그 관계를 창업가의 개인적 특성(성별, 연령)과 국가 간 창업환경의 차이가 어떻게 조절하는지 실증했다. 이를 위해 직장에 소속된 표본 3,285개(한국 1,042명, 중국 1,379명, 미국 865명)를 대상으로 조절변수를 포함한 회귀분석을 시행했다. 분석 결과, 기업가정신의 하위차원인 혁신성, 진취성, 위험감수성은 모두 창업 의도에 정(+)의 영향을 끼쳤다. 성별의 조절효과는 위험감수성과 창업 의도 간에 관계에서만 유의했는데, 여성일 때 위험감수성이 높아질수록 창업 의도가 좀 더 강해졌다. 연령의 조절효과는 혁신성과 진취성이 창업 의도에 미치는 영향에 대해 유의미했는데, 혁신성은 연령대가 높을 때, 진취성은 젊은 층에서 강화 관계가 나타났다. 그러므로 관련 교육 프로그램을 설계할 때 여성과 중장년층, 청년층에 적합한 내용을 맞춤식으로 제공한다면 기업가정신이 창업으로 좀 더 강하게 발현할 수 있을 것이다. 마지막으로 국가 간 창업환경에 의한 차이는 확인할 수 없었다. 국가별 대규모 표본을 수집하였으며 직장에 소속된 잠재적 창업가의 기업가정신과 창업 의도를 살펴보았다는 차별점을 가진다. 그럼에도 자기보고식 응답에 의존하여 분석한 점, 기업가정신 교육의 수료 정도, 국가 간 차이를 측정하는 다양한 변수 등을 포함하지 않고 분석했다는 한계가 존재한다. Today, as the structural economic downturn continues, the importance grows for the technology-based startups and thus there is a need for a research on the factors that turn the entrepreneurship into launching of a business. This study revealed the positive (+) relationship between entrepreneurship and entrepreneurial intention and demonstrated how the relationship is moderated by the entrepreneur s personal characteristics (gender, age) and the differences in entrepreneurship environment between countries. To this end, regression analysis which included moderating variables was done for 3,285 samples employed in the workplace (1,042 in Korea, 1,379 in China, and 865 in the US). As a result of the analysis, innovativeness, initiative, and risk sensitivity, which are the sub-levels of entrepreneurship, had a positive (+) effect on the entrepreneurial intention. The moderating effect of gender was significant only in the relationship between risk sensitivity and entrepreneurial intention. Particularly, in the case of women, the higher the risk sensitivity, the stronger the entrepreneurial intention became. The moderating effect of age was significant in terms of the effect of innovativeness and initiative on entrepreneurial intention. Innovativeness was reinforcing among older age groups while initiative, among younger ones. Therefore, when designing related education programs, the entrepreneurship is more likely to lead to a business launching if the content is more appropriately tailored to the female group, the middle-aged, and the younger generation. Lastly, the difference could not be confirmed between the countries due to the entrepreneurship environment. The significance of this study is that it has collected a large sample from each country and that it examined the entrepreneurship and the entrepreneurial intention of potential entrepreneurs still employed at the workplace. Nevertheless, there is a limit to the study in that the analysis was based on self-reported responses and that the various variables were not included such as the completion level of entrepreneurship education or the differences between countries.
