        The Impact of Technology Licensing Payment Mechanisms on Firms’ Innovative Performance: Evidence from Small- and Medium-Sized Enterprises

        이정은,김영훈,최동혁,김연배 한국혁신학회 2010 한국혁신학회지 Vol.5 No.2

        Although numerous papers have examined the ways in which firms can improve their innovative performance through technology alliances, empirical research on the effect of contract structures in technology licensing has been scarce. This study provides evidence that the payment mechanisms agreed upon in licensing contracts affect the licensee firms’innovative performance. Based on a dataset of technology licensing contracts concluded by small- and medium-sized enterprises around the world, this paper analyzes the influence of fixed-fee payments and ongoing payments-including royalty, milestone, and equity payments-on firm performance. The findings reveal that ongoing payments are more likely to positively influence the innovative performance of licensee firms. These outcomes provide crucial insights into the ways in which small high-tech firms can utilize their external technology resources.

      • 시외버스터미널 인근 초미세입자(PM2.5)와 블랙카본(BC) 실시간 농도 사이의 상관성 평가 : 부천과 안산 지역

        이정은,박수정,윤동민,김성렬 순천향대학교 기초과학연구소 2017 순천향자연과학연구 Vol.23 No.2

        The objective of this study was to measure concentrations of black carbon(BC) and particulate mätters with äerödynämic diämeter öf 2.5 μm ör less (PM2.5) which were potentially emitted from mobile diesel emission related sources. PM2.5 and BC measurements were conducted with SidePak AM510 Personal Aerosol Monitor (TSI, Inc., St. Paul, MN) and MicroAeth Model AE51 (Magee Scientific, Berkeley, CA). Our measurements were conducted on weekdays between 8 a.m. and 10 a.m., and between 6 p.m. and 8 p.m. to capture the morning and afternoon distributions of these pollutants during the daily rush-hour period from October, 2012, to March, 2013. Local bus terminals have been selected randomly for convenient sampling. The data logging interval was one minute for both PM2.5 and BC. The median concentrations of PM2.5 and BC were 30.1 g/m3 and 8.3 g/m3 at bus terminals. The overall correlation coefficient between PM2.5 and BC was 0.6 and the coefficients ranged from 0.5 to 0.7 depending on our selected sampling site. In this study, we found median or high correlation coefficients between PM2.5 and BC concentration at bus terminals coupled by diesel vehicles and association, between two pollutants were likely different depending on time and space

        International Human Rights Regime and Domestic Politics in South Korea: An Analysis of the Human Rights Agenda between 1948-1960

        이정은 한국학중앙연구원 한국학중앙연구원 2008 THE REVIEW OF KOREAN STUDIES Vol.11 No.3

        This paper treats historically the implications of a human rights agenda under the Syngman Rhee government during the 1950s. In the process of forming an international human rights regime and the reorganization of the world order after World War II, Korea was introduced to basic rights and human rights as a modular mechanism of a nation-state. With the establishment of the Republic of Korea, the basic rights of the people were provided for in the constitution and the government commemorated Human Rights Day and Human Rights Week. Apart from the influence of the international human rights regime, the political tactics of the Syngman Rhee government worked largely to institutionalize domestic human rights. Arguing that it was “the only legal government recognized by the United Nations,” the government began to commemorate and propagate United Nations Human Rights Day. Commemorated since 1950, it worked as an instrumental justification to maintain the anticommunist state of Syngman Rhee.

        독거노인의 사회서비스 욕구 유형 및 특성에 관한 연구

        이정은,류진아,하태정,오다은 충남대학교 사회과학연구소 2021 사회과학연구 Vol.32 No.3

        The purpose of this study is to identify the types of social service needs of older adults living alone, and to examine the characteristics and various predictive factors of each type. In order to achieve these study objectives, 552 single households aged 65 and over were analyzed from the data of the 2019 Social Service Demand and Supply Survey. First, we conducted latent class analysis to classify latent groups representing similar patterns of social service needs. Multinomial logistic regression was then conducted to identify the characteristics and influencing factors of each group type. As a result, the latent groups of older adults living alone considering the type of social service needs were classified into three groups: health/social participation/leisure-oriented cluster (8.7%), health/adult care/residential environment-oriented cluster (22.1%), and health-oriented cluster (69.1%). Results of multinomial logistic analysis revealed that the common factor separating the ‘health-oriented cluster’ and the other two groups was the subjective economic level. Based on this study, various policy interventions need to be implemented based on the complex needs of older adults living alone. In addition, this study can be used as a basis for designing customized services for integrated case management of older adults living alone. 본 연구는 독거노인의 사회서비스 욕구 유형을 확인하고, 각 유형별 특성 및 다양한 예측 요인을 파악하는 것을 목적으로 한다. 이를 위해 ‘2019년 사회서비스 수요․공급 실태조사’ 자료를 활용하여 만 65세 이상 노인 1인가구 552가구를 대상으로 분석을 실시하였다. 비슷한 욕구 패턴을 보이는 잠재 집단들을 분류하기 위해 잠재계층분석(Latent Class Analysis)을 수행하였으며, 다항로지스틱 회귀분석(Multinomial logistic regression)을 실시하여 각 집단 유형별 특성과 영향요인을 확인하였다. 잠재계층분석 결과, 독거노인의 사회서비스 욕구 유형은 ‘건강/사회참여/문화여가 중심형(8.7%)’, ‘건강/돌봄/주거환경 중심형(22.1%)’, ‘건강 중심형(69.1%)’이라는 상이한 사회서비스 욕구 패턴을 갖는 집단으로 구분되었다. 학력이나 주관적 경제상태가 높고 대도시에 거주하는 독거노인의 경우 복합적 욕구의 출현이 낮은 것으로 나타났다. 다항로지스틱 분석에서는 ‘건강중심형’과 나머지 두 집단을 구분하는 공통 변인은 주관적 경제상태인 것을 확인하였다. 이러한 분석 결과를 바탕으로 독거노인의 욕구에 기반한 다양한 정책적 개입과 함께 독거노인의 통합사례관리를 위한 맞춤형 서비스 설계의 필요성을 제안하였다.

        The purpose of this study was to determine the relationship between structural elements of community of practice and individual and organizational performance. The population of the study was all member of community of practice in Korean corporate. Using the purposeful sampling technique, 530 members of 23 companies were sampled for this study. A survey questionnaire was developed by research to collect the information needed for the study, which consisted of structural element scale, individual and organizational performance. The scale consisted of 5-point Likert-type. Two hundred eighty seven out of 530 questionnaires were returned (a response rate of 59.8%), of which two hundred sixty nine were used for analysis after data cleaning. Based on the findings of the study, the structural elements of community of practice had a significant relationship with the individual and organizational performance of community of practice. The individual performance was explained by domain, community, and practice. And the organizational performance was explained by domain and practice. That is individual performance will be high as the structural elements of community of practice prepared. Especially, it is important sharing and creating of the knowledge through the relationship and membership of members in individual performance. In organizational performance, it is important to select and share adaptable topic, and share and create knowledge through the participation. And actual knowledge sharing and creation will make better organizational performance. 이 연구의 목적은 실행공동체의 구조적 요인과 개인 및 조직성과의 관계를 구명하는데 있었다. 모집단은 기업체 임직원들 중 실행공동체 활동을 경험한 사람들이었으나, 이들에 대한 현실적인 접근성의 제약으로 인해 유의표집(purposive sampling)을 사용하여 총 23개 기업의 실행공동체 참가자 530명을 조사대상으로 선정하였다. 조사도구는 실행공동체 구조적 요인, 개인 및 조직성과, 실행공동체 특성, 개인특성 조사문항으로 구성된 질문지를 사용하였으며, 이는 선행연구를 바탕으로 한 내용 구조화, 전문가 검토, 예비조사를 거쳐 개발되었다. 최종 개발된 실행공동체 구조적 요인 척도는 지식의 영역 4문항, 공동체 9문항, 프랙티스 7문항으로 총 20개의 문항이었고, 개인 및 조직성과 척도는 개인성과 12문항, 조직성과 19문항으로 5점 척도로 반응하도록 구성되었다. Cronbach의 α값은 지식의 영역 0.87, 공동체 0.95, 프랙티스 0.85, 개인성과 0.94, 조직성과 0.96이었다. 자료수집은 우편조사 및 방문조사를 통해 이루어졌고, 총 287개가 수집되어 회수율은 약 59.8%였다. 이중 일부 자료는 무응답 및 불성실응답 등의 이유로 제거되어 최종분석에는 269명의 자료가 사용되었다. 분석결과, 개인성과는 지식의 영역, 공동체, 프랙티스와 통계적으로 유의미한 높은 정적 상관을 보였고, 이들 모두가 개인성과를 유의하게 설명하는 예측변인으로 나타났다. 또한, 조직성과는 지식의 영역, 공동체, 프랙티스와 통계적으로 유의미한 높은 정적 상관을 보였고, 지식의 영역과 프랙티스만이 조직성과를 유의하게 설명하는 것으로 나타났다. 즉, 실행공동체의 구조적 요인이 잘 갖추어질수록 개인성과가 높아지며, 특히 구성원들 간의 유대감과 소속감의 향상과 적극적인 참여를 통한 지식의 공유와 창출이 개인성과 향상에 매우 중요하다. 조직성과도 적합한 주제 선정과 이것의 공유, 적극적인 참여를 통한 지식 공유와 창출이 매우 중요하며, 개인성과를 넘어 조직성과를 항상 시키기 위해서는 실제로 지식 공유와 창출 활동이 활발하게 일어나야 한다. 이러한 결론을 토대로, 실행공동체 구조적 요인에 대한 더욱 세부적이고 다양한 후속연구들이 계속되기를 제안한다.
