This study empirically examines how policy instrument impacts technological innovation and it also investigates the moderating effects of industry-specific characteristics on the relationship between policy instrument and technological innovation, using 2016 Korean Innovation Survey(KIS) by STEPI. This article classifies policy instrument into regulation, incentives, and information by typology of Vedung(1998). The characteristics of industry are divided into supplier-dominated sector, specialized-suppliers sector, scale-intensive sector and science-based sector according to Pavitt(1984). The main findings are as follows. A multiple regression analysis demonstrates that a high level recognition of regulation and information increases technological innovation, whereas a high level recognition of incentives decreases it. Following regression analysis shows that production intensive sector and science-based sector negatively affect technological innovation. The positive effect of incentives becomes stronger in science-based sector and the positive effect of information gets stronger in production intensive sector. Overall, this study suggests that government support policy needs to be more specific by taking the characteristics and context of enterprises into consideration.

투입산출 구조분해를 통해 본 자동차산업의 성장기여율 분석

원희연,박재운 한국산업경제학회 2009 산업경제연구 Vol.22 No.2

본 연구의 목적은 투입산출 구조분해 (Input-Output Structural Decomposition Analysis)를 통해 자동차산업의 요인별 성장기여율을 분석하는 것이다. 구조분해 분석결과 요인별 성장기여율은 2003-2005년 기간 중 수출수요(38.2%), 기술변화(38.2%), 최종수요(24.5%)의 순으로 나타났다. 국내소비와 투자에 의해 크게 영향을 받는 최종수요 성장기여율이 최근 들어 급격히 낮아졌는데, 동 기간 중 국내소비 및 투자액 감소에 기인한다. 이는 자동차산업에 있어서 국내소비나 투자가 활성화 되지 않을 경우 최종수요의 성장기여율은 낮아질 수밖에 없다는 것을 의미한다. 따라서 자동차산업에 대한 소비활성화 및 중기적 관점의 투자활성화가 필요하다. 또한 수출수요 성장기여율 역시 최근 들어 이전기간의 성장 폭을 훨씬 밑돌고 있을 뿐만 아니라 정체상태를 보이고 있다. 따라서 완성차의 수출확대뿐만 아니라 자동차용엔진 및 부분품에 대한 수출활로를 보다 적극적으로 모색할 필요가 있다. 최종재수입대체 성장기여율의 경우 가장 최근의 두 분석기간 모두 마이너스를 보여 수입최종재로의 대체가 나타났다. 이는 국산최종재로의 대체비율이 낮아져 최종재에 대한 수입의존도가 높아졌다는 의미이다. 따라서 국산자동차에 대한 인지도 제고 및 품질경쟁력을 높일 수 있는 방안 또한 필요하다. The objective of this study is to examine a contribution to the main growth factors on the Korean motor vehicles industry by the input-output structural decomposition analysis. Major findings of this study are as follows; First, Korean motor vehicles industry's demand for export (38.2%), technological change(38.2%), and final demand(24.5%) play key roles among the growth factors. In conclusion, a growth contribution to the final demand has decreased sharply during the Year 2003-2005. This is due to the decreasing of domestic consumption and investment. Thus, for the sustainable growth of the Korean motor vehicles industry, it is required to Promote the motor vehicles industry-related domestic consumption and to enlarge the midterm-based relating R&D investment. It is required not only to expand the motor vehicles-related export, but also to enlarge the motor vehicles-related parts and components aggressively, because the growth contribution to the demand for export has decreased or stagnated since the Year 2000-2003

Enhancement of Allergen-induced Airway Inflammation by NOX2 Deficiency

원희연,황은숙,장은정,민현정 대한면역학회 2011 Immune Network Vol.11 No.3

Background: NADPH oxidase (NOX) modulates cell proliferation,differentiation and immune response through generation of reactive oxygen species. Particularly, NOX2 is recently reported to be important for regulating Treg cell differentiation of CD4+ T cells. Methods: We employed ovalbumin-induced airway inflammation in wild-type and NOX2-deficient mice and analyzed tissue histopathology and cytokine profiles. Results: We investigated whether NOX2-deficiency affects T cell-mediated airway inflammation. Ovalbumin injection which activates T cell-mediated allergic response increased airway inflammation in wild-type mice, as evidenced by increased immune cell infiltration, allergic cytokine expression,and goblet cell hyperplasia in the lung. Interestingly,NOX2 knockout (KO) mice were more susceptible to allergen-induced lung inflammation compared to wild-type mice. Immune cells including neutrophils, lymphocytes, macrophages,and eosinophils were drastically infiltrated into the lung of NOX2 KO mice and mucus secretion was substantially increased in deficiency of NOX2. Furthermore, inflammatory allergic cytokines and eotaxin were significantly elevated in NOX2 KO mice, in accordance with enhanced generation of inflammatory cytokines interleukin-17 and interferon-γ by CD4+ T cells. Conclusion: These results indicate that NOX2 deficiency favorably produces inflammatory cytokines by T cells and thus increases the susceptibility to severe airway inflammation.

Transcriptional modulation of regulatory T cell development by novel regulators NR4As

원희연,Eun Sook Hwang 대한약학회 2016 Archives of Pharmacal Research Vol.39 No.11

Regulatory T (Treg) cells with high expressionof both CD25 and Foxp3 are developed in the thymus andalso peripheral tissues. Treg cells suppress the activationand functions of effector T cells raised against specificantigens and are crucial for maintaining immune home-ostasis. Treg cell development is associated with theinduction of and epigenetic alterations of forkhead tran-scription factor Foxp3. Foxp3 expression is increased bythe activation of several transcription factors includingnuclear factor-kappa B (NF-jB), nuclear factor of activatedT cells (NFAT), and Smad3 in response to various signalssuch as TGFb, retinoic acid, and rapamycin. Recently, theorphan nuclear receptor 4A proteins (NR4As) includingNR4A1 (Nur77), NR4A2 (Nurr1), and NR4A3 (Nor1) arereported to regulate Treg cell development through acti-vation of Foxp3 and have therapeutic potentials in treatingimmune disorders. This review summarizes the functionand regulatory mechanisms of Treg cells and also impli-cates current advances in immunomodulatory functions ofNR4As and their therapeutic potentials in inflammationand cancer.

공공기관의 전략과 정당성-한국농수산식품유통공사 사례 분석

원희연 ( Hee-yeoun Won ) 국민대학교 사회과학연구소 2020 社會科學硏究 Vol.33 No.1

본 연구에서는 공공기관의 전략과 정당성에 관하여 검토하기 위하여, Boyne & Walker (2004)의 전략 자세(strategic stance) 유형에 관한 이론과 Suchman(1995)의 정당성에 관한 이론을 aT(한국농수산식품유통공사)에 적용하였다. 연구 결과, 첫째, Boyne & Walker(2004) 전략 유형 분류를 적용하였을 때, 공공기관도 상위기관의 지시에 수동적으로 따르는 반응형(reactor) 뿐만 아니라, 주도적이고 능동적으로 변화에 대응하는 공격형 (prospector)이나 방어형(defender) 전략을 사용한다는 점을 확인할 수 있었다. 둘째, 실질적 정당성(pragmatic legitimacy) 뿐만 아니라 도의적 정당성(moral legitimacy), 인지적 정당성(cognitive legitimacy)이 공공조직 변화의 원인이 되며, 공공기관의 변화를 결정 하는 타 상위기관의 근거가 된다. This historical research examines the strategy and the legitimation of Korea Agro-Fisheries & Food Trade Corporation, which is a public institution in the quasi-governmental sector. This article classifies strategic stances into prospector, defender, and reactor according to the typology of Boyne & Walker(2004). The characteristics of legitimacy are divided into pragmatic legitimacy, moral legitimacy, and cognitive legitimacy according to Suchman(1995). The main findings are as follows. First, public organizations in the quasi-governmental sector act as prospectors and defenders, not only as reactors. Second, moral legitimacy and cognitive legitimacy can cause structural changes of public institutions. In particular, changes of public organizations are warranted in the eyes of government, the president or the assembly, on a basis of moral and cognitive legitimacy as well as pragmatic legitimacy. This suggests the reasons for changes in public organizations differ from in private institutions.
