Leveraging electronic collaboration to promote interorganizational learning     

Sujeong Choi  Ilsang Ko 《International Journal of Information Management》2012

By combining research on interorganizational learning (IOL) with that on IT-enabled collaboration, this study examines the role of electronic collaboration (e-collaboration) enabled through the use of interorganizational information systems in the development of a firm's capabilities such as IOL. Moreover, this study examines IOL as a capability posited between electronic collaboration and firm performance. Finally, we conceptualize IOL as a multidimensional construct composed of information sharing, relationship-specific knowledge memory, and the development of shared meaning and verify the relationships between them. The study provides an empirical analysis of the proposed model and hypotheses by considering data from various industries. The results indicate that e-collaboration was positively related to all three components of IOL. In terms of the relationships between these components, information sharing had a positive effect on relationship-specific knowledge memory, which in turn facilitated the development of shared meaning. Only the development of shared meaning had a significant effect on firm performance. Discussions and implications of the results are provided.  相似文献   

Congenital atresia of the left main coronary artery in an infant     

Su Ye Sohn  Gi Young Jang  Byung Min Choi 《Journal of Zhejiang University. Science. B》2010,11(7):539-541

Congenital atresia of the left main coronary artery is a rare occurrence, and surgical revascularizationbypass graft is required. We here report a rare case of congenital coronary anomaly in an infant. A 10-month-old male infant was admitted to the hospital with heart failure symptoms. Echocardiographic examinations revealed mitral valve regurgitation and ischemic changes of the anterolateral papillary muscle and chordae. Coronary angiography showed atresia of the left main coronary artery with a severe hypoplastic left anterior descending artery and a circumflex coronary artery. Unfortunately, sudden cardiac arrest occurred after catheterization and the infant did not recover despite of immediate cardiopulmonary resuscitation. Further studies are needed to find a newer diagnostic method to detect coronary anomaly in an infant, and coronary angiography, if necessary, has to be performed very carefully.  相似文献   

Comparative analysis of OECD member countries’ competitive advantage in National Human Resource Development system     

Hunseok Oh  Yeseul Choi  Myungweon Choi 《Asia Pacific Education Review》2013,14(2):189-208

The purpose of this study was to assess, evaluate, and compare the competitive advantages of the human resource development systems of advanced countries. The Global Human Resource Development Index was utilized for this study, since it has been validated through an expert panel’s content review and analytic hierarchy process. Using a sample of 34 OECD member countries, the following conclusions were drawn. First, Switzerland, Sweden, and United States ranked top three in order in National Human Resource Development (NHRD) competitiveness and such Nordic countries as Sweden, Finland, Denmark, Norway, and Iceland showed outstanding NHRD competitiveness. Second, thirty-four countries differed significantly in key aspects of supply, demand, environment, and supporting systems of NHRD. Strong, intermediate, and weak groups classified based on NHRD competitiveness significantly differed from one another in all factors of the NHRD system. Third, changes in NHRD competitiveness between 2005 and 2011 did not exhibit specific patterns depending on the level of economic development. Fourth, little changes in NHRD system occurred in a short period of time. The most significant positive changes in NHRD competitiveness were identified in only two cases of Luxemburg (△6) and Poland (△6) among 34 countries. Only striking case of decrease in NHRD competitiveness was Israel (▽6). The findings of this research will be able to assist each country in identifying its strengths and weaknesses in the NHRD system.  相似文献   

Molecular diffusion analysis of dynamic blood flow and plasma separation driven by self-powered microfluidic devices     

Sung Oh Woo  Myungkeun Oh  Kyle Nietfeld  Bailey Boehler  Yongki Choi 《Biomicrofluidics》2021,15(3)

Integration of microfluidic devices with pressure-driven, self-powered fluid flow propulsion methods has provided a very effective solution for on-chip, droplet blood testing applications. However, precise understanding of the physical process governing fluid dynamics in polydimethylsiloxane (PDMS)-based microfluidic devices remains unclear. Here, we propose a pressure-driven diffusion model using Fick''s law and the ideal gas law, the results of which agree well with the experimental fluid dynamics observed in our vacuum pocket-assisted, self-powered microfluidic devices. Notably, this model enables us to precisely tune the flow rate by adjusting two geometrical parameters of the vacuum pocket. By linking the self-powered fluid flow propulsion method to the sedimentation, we also show that direct plasma separation from a drop of whole blood can be achieved using only a simple construction without the need for external power sources, connectors, or a complex operational procedure. Finally, the potential of the vacuum pocket, along with a removable vacuum battery to be integrated with non-PDMS microfluidic devices to drive and control the fluid flow, is demonstrated.  相似文献   

Employees’ perceptions of interpersonal competence: The case of South Korea     

Changdai Kim  Kyung Wha Min  Sook Kyeong Yune  Hanna Choi  Eun Hye Gong 《Asia Pacific Education Review》2008,9(2):221-232

This study examined employees’ perceptions of interpersonal competence at work through the research methodology known as concept mapping. The purpose of this study was to identify the phenomenally derived components of interpersonal competence in work environments and employees’ underlying cognitive structures of interpersonal competence at work. Multidimensional scaling analysis indicated that the participants conceptualized interpersonal competence in the following two dimensions: (i) work-specific domain versus general domain and (ii) unilateral domain versus bilateral domain. In addition, hierarchical clustering on the MDS coordinates produced six clusters: Caring & Considerate, Sociable & Out-going, Kind & Gentle, Reliable & Leadership skills, and Confident & Responsible. Our results were discussed with respect to future research and educational approaches to the issues surrounding interpersonal competencies at work.  相似文献

Data‐driven refinements of a genetics learning progression     

Moraima Castro‐Faix  Ravit Golan Duncan  Jinnie Choi 《科学教学研究杂志》2021,58(1):3-39

Learning progressions are theoretical models that describe learning of scientific ideas and practices over time. These hypothetical progressions need to be tested and refined in order to productively inform instruction and assessment. In this paper, we report our attempts to revise a learning progression in genetics. In particular, we focused on two constructs that embody core ideas in classical genetics and one molecular construct. The revisions are based on analysis of pre‐ and postinterview data obtained from sixty 11th grade students before and after they engaged in a 10‐week unit that addressed these concepts. We found that while many of the students held ideas that aligned with the progression, there were several distinct dimensions of student reasoning that were not captured and led to substantial revisions of the constructs including: (a) the splitting of the construct dealing with meiosis (E) into two subconstructs (E1‐physical passage of genetic information and E2 – the role of sex cells), (b) the addition of new levels to constructs dealing with the universal nature and organization of the genetic code (A) and construct (F). For Construct A, the lower levels were expanded to include ideas about the localization of DNA in cells and to include ideas about the composition of DNA that were not captured in the progression. Revisions to Construct F included the expansion of existing levels and the addition of modes of inheritance such as codominance and incomplete dominance. The research we present offers insights about a methodological approach that can be used to test and refine progressions, as well as insights about student learning in genetics as we further describe and expand the stepping‐stone ideas in the progression and discuss further the multidimensional nature of learning progressions.  相似文献   

An analysis of the nature of epistemological beliefs: Investigating factors affecting the epistemological development of south korean high school students   总被引：1，自引：0，他引：1  

Inn Youn  Kye-Min Yang  In-Jae Choi 《Asia Pacific Education Review》2001,2(1):10-21

The purpose of this study is to investigate the nature of epistemological beliefs about learning (or learning beliefs) by analyzing the type of factors involved in the epistemological development of South Korean high school students (N=455). Learning beliefs are implicit assumptions held by learners about the source and certainty of knowledge and the ways to obtain knowledge. Previous studies on the epistemological development of American high school students showed that American students learning beliefs are positively related with their age, amount of formal education, and academic achievement. Multiple regression analysis of this study, however, showed that no such relationships were identified from the present South Korean sample except between students beliefs and their academic achievement. In addition, the present study showed that South Korean students learning beliefs were related with their independent-self construal (individualistic self-view) but not with their interdependent self-construal (collectivistic self-view). These results reconfirmed the culture-specific nature of epistemological beliefs which was identified from previous comparative studies with South Korean and American college students (Youn, Kim, & Yang, 1999; Youn, 2000). The differences between the present results and previous findings with South Korean college students will be further discussed in terms of the sub-cultural variations between South Korean young generations.

Out of the book and into the classroom: The experiences of Korean social studies pre-service teachers in an international teaching practicum in the United States     

Yeji Kim  Minsik Choi 《Asia-Pacific Journal of Teacher Education》2019,47(2):176-192

Despite the growing interest and importance of pre-service teachers’ cross-cultural experiences, a review of the literature shows that few studies have discussed the international teaching practicum experiences of pre-service teachers from Asian countries. Bridging this gap, this qualitative case study examined the perceptions and experiences of 15 Korean social studies pre-service teachers who participated in an international teaching practicum in the United States. The findings of the study demonstrated that although participants encountered difficulties in speaking a foreign language and adjusting to a different culture, they also gained confidence and self-efficacy by negotiating and actively participating in the teaching and learning process. This international teaching practicum also helped participants promote their own understanding of multiculturalism and their different perspectives of the teachers’ roles, teaching pedagogies, and local education systems. This study offers implications for future multicultural professional development in teacher education and contributes to developing a body of research and scholarship on international teaching practicums from Asian contexts that have, to date, been largely underexplored.  相似文献
