본 연구는 상사의 변혁적 리더십이 지식경영활동과 조직몰입에 어떠한 영향을 미치는지를 분석하였으며, 상사의 변혁적 리더십과 조직몰입의 관계에서 지식경영활동이 매개효과를 나타내는지를 분석한 실증연구이다. 이를 위한 연구방법으로서 본 논문은 서비스/제조/IT 대기업 종사자 635명을 대상으로 설문조사를 실시하였고, 이를 토대로 산업별 변수간의 관계에 대하여 비교 분석하였다. 본 연구에서 사용한 용어에 대한 정의를 살펴보면, 변혁적 리더십은 목표달성에 그치지 않고 변화와 혁신을 추구하며, 조직구성원들이 지니고 있는 잠재적 역량과 강점을 개발하고 자신감과 열정을 증대시키며, 긍정적 강점을 자극하여 기대했던 것보다 높은 성과를 달성하도록 한다. 이러한 변혁적 리더십은 조직유효성을 증진시키는 선행요인으로 중요하게 인지되었다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 상사의 변혁적 리더십이 지식경영활동에 모두 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 상사의 변혁적 리더십이 조직몰입에 모두 유의한 정(+)의 영향을 미치는 것으로 나타났다. 셋째, 지식경영활동도 조직몰입에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 넷째, 상사의 변혁적 리더십이 조직몰입간에 지식경영활동의 매개역할에 관해서 부분매개효과를 나타내는 것으로 분석되었다. 다섯째, 각 집단별로 분석해보면 상사의 변혁적 리더십이 지식경영활동에 미치는 영향에서는 서비스업이 가장 큰 것으로 나타났으며, 지식경영활동이 조직몰입에 미치는 영향에서도 서비스업이 가장 큰 것으로 나타났다. 또한 상사의 변혁적 리더십이 조직몰입에 미치는 영향에서는 IT업이 가장 큰 것으로 나타났다. 마지막으로 위와 같은 분석결과를 토대로, 변혁적 리더십이 지식경영활동과 조직몰입에 미치는 영향에 대한 결과의 의미와 산업별 차이에 대한 의미를 중심으로 시사점을 논의하였고 연구의 한계점도 제시하였다.

KOIN(한의 사람들, http://www.koin.re.kr)은 한의학에 관심 있는 사용자들이 한의 정보를 공유할 수 있도록 구축된 한의 지식 포털이다. 본 연구의 목적은 KOIN을 본격적으로 서비스하기 전에 향후 KOIN 서비스에 대한 사용자 확보를 위해 콘텐츠와 서비스 측면에서 질적 고도화 방안을 모색하는 데 있다. 이를 위해 크라우드 테스팅 기법을 활용하여 현재 KOIN의 기능성 및 사용성 테스트를 수행하였으며, 국내외에서 KOIN과 유사한 사이트를 조사해 비교하였다. 기능성 테스트 결과 약 150여 개의 기능적 문제점이 발견되어 수정하였으며, 사용성 테스트에서는 평균 3.33점이 나왔는데, 이 중 신뢰성 점수가 가장 높았고 유희성 점수가 가장 낮았다. 또한, 국내외 의료분야에서 KOIN과 유사한 15개의 웹사이트들에 대해서 특징 및 장단점을 분석해서 KOIN의 개선 방향을 도출하였다. 특히, KOIN은 다른 포털들에 비해 근거에 기반한 한의 지식을 제공하는 장점을 가진 것으로 분석되었다. 향후에도 사용자의 요구 사항을 지속적으로 수집하여 사용자들이 필요로 하는 한의 지식 서비스를 제공할 수 있도록 할 계획이다.

This paper explores the role of entrepreneurship education in a modern economy and how the government, academic, and nonprofit sectors in the United States have responded to this growing field. There are several sectors that play important roles in the entrepreneurship education landscape in the United States. Over the past decade, there has been increasing participation of Federal and state governments. This recent trend suggests the field may be increasing in maturity and legitimacy, showing promise for expanding the reach of entrepreneurship education programs. Programs sponsored by nonprofit organizations and private foundations complement government initiatives and display an effective means of leveraging knowledge and resources across the relevant sectors. Thus, new initiatives, whether initiated by government or academia, should learn from the successes of this sector as well as be carefully considered within the context of existent programs and services. Nonetheless, the potentially dynamic environment of the entrepreneurship education field in the United States offers a specific opportunity to leverage the experience in mentorship activities at the post-secondary education to address a possible gap in these activities at the secondary education level.

This study presents a model to better understand the shear behavior of reinforced concrete walls subjected to lateral load. The scope of the study is limited to squat walls with height to length ratios not exceeding two, deformed in a double-curvature shape. This study is based on limited knowledge of the shear behavior of low-rise shear walls subjected to double-curvature bending. In this study, the wall ultimate strength is defined as the smaller of flexural and shear strengths. The flexural strength is calculated using a strength-of-material analysis, and the shear strength is predicted according to the softened strut-and-tie model. The corresponding lateral deflection of the walls is estimated by superposition of its flexibility sources of bending, shear and slip. The calculated results of the proposed procedure correlate reasonably well with previously reported experimental results.

As reflected in the title, the main objective of the paper is to explore an appropriate approach to promote technological innovation for developing countries. Aiming to this goal, the paper studies three main innovation system approaches, whose implantation is being attempted in developing countries: first, national innovation systems (NIS), which was developed in OECD countries; second, the system of innovation for development (SID), which is a concept that tries to adapt NIS to developing countries; and third, inclusive innovation which is a pro-poor innovation system. Based on the strengths and the weaknesses of each concept and their potential adaptation in developing countries, the paper proposes an integrated approach of innovation system for developing countries. Compared to developed countries, the concept of innovation system in developing countries should be more complex because it involves not only the formal sector such as enterprises, universities, research institutes, government, and financial system but it also involves NGOs, informal companies, grassroots inventors, local and indigenous knowledge, etc. The last part of the paper discusses the ideas that innovation stakeholders in developing countries can use to promote their proper innovation system.

Deep Learning is used nowadays in Nuclei segmentation. While recent developments in theory and open-source software have made these tools easier to implement, expert knowledge is still required to choose the exemplary model architecture and training setup. We compare two popular segmentation frameworks, U-Net and Mask-RCNN, in the nuclei segmentation task and find that they have different strengths and failures. we compared both models aiming for the best nuclei segmentation performance. Experimental Results of Nuclei Medical Images Segmentation using U-NET algorithm Outperform Mask R-CNN Algorithm.

Project-based joint ventures are often used in the construction industry to assemble an organization that meets a client's project needs and matches or exceeds the capacities of competitors. The joint venture / partnerships provides the means for a firm to quickly add resource, political, technical, or other required strengths that will increase project acquisition. This paper sets out to study the types of joint ventures, different issues or problems while having joint ventures and the critical factors that contribute to successful joint ventures. A questionnaire was designed and administered to survey the issues and present practices of joint ventures in the South Florida construction industry. Along with the questionnaire, personnel interviews were also conducted to get first hand knowledge about the subject matter. The results are presented in the paper. These results specifically identify the overall practice of joint ventures in South Florida as well as indicate the most significant factors leading to failure or success of these ventures.

Facilitating critical thinking is important for students' cognitive growth and knowledge acquisition. This study examines the dimensions of tutors' roles in facilitating the critical thinking required for problem solving in online discussions. The research procedures include identifying the research problems related to critical thinking skills; synthesizing theories and perspectives on critical thinking skills; and analyzing, validating, and determining tutors' roles. Using the results of this study, problem solving processes are divided into four phases: analyzing, judging, inferencing, and meta-cognitively evaluating. Tutors' roles in online problem solving can be categorized into four domains: cognitive, social, managerial, and technical. Tutors' roles in each domain are specifically analyzed, and the strengths, weaknesses, and improvements in tutors' facilitation of critical thinking for online problem solving are evaluated.
