Moving Singapore from great to excellent : How educational research informs this shift

Shu-Shing Lee,David Hung,Laik Woon Teh 한국교육개발원 2013 KEDI Journal of Educational Policy Vol.10 No.2

The McKinsey report on how the world’s most improved school systems keep getting better evaluated Singapore as a “great” system (Mourshed, Chijioke, & Barber, 2010). While the report identifies factors, such as high quality teachers, that enable high-performing systems to do well, it does not provide suggestions on how countries can shift from “great” to “excellent”. This paper takes a systemic, ecological view to discuss how educational research invested in five levels of the education system― the history and society; cross systems; whole system; school; and classroom levels― can yield research findings that may inform Singapore on how to make this shift. Three areas of change are proposed to help Singapore’s efforts towards excellence ? 1) a more balanced teacher-centric and student-centric pedagogy, 2) improving the performance of lower achieving students, and 3) greater diversity of talent recognition beyond academic achievements.

Performance of Q-learning based resource allocation for D2D communications in heterogeneous networks

Lee Shu-Hung,Shi Xiao-Pei,Tan Tan-Hsu,Lee Yu-Lin,Huang Yung-Fa 한국통신학회 2023 ICT Express Vol.9 No.6

This study investigates energy efficiency issues of device-to-device (D2D) communications in heterogeneous networks. To minimize the total transmitted power, an approach based on Q-learning together with adaptive ɛ -greedy is proposed to optimize the connection of user equipment (UE) with base station (BS) or access point (AP). The proposed adaptive ɛ -greedy can conduct the adequate exploration and exploitation operations for effective optimization. Simulation results indicate that in the single-cell scenario, the proposed method can attain performance close to the best solution.

Taiwanese Parents’ Experience of Making a “Do Not Resuscitate” Decision for Their Child in Pediatric Intensive Care Unit

Shu-Mei Liu,Hung-Ru Lin,Frank L. Lu,Tzu-Ying Lee 한국간호과학회 2014 Asian Nursing Research Vol.8 No.1

Purpose: The purpose of this project was to explore the parental experience of making a “do not resuscitate” (DNR) decision for their child who is or was cared for in a pediatric intensive care unit in Taiwan. Methods: A descriptive qualitative study was conducted following parental signing of a standard hospital DNR form on behalf of their critically ill child. Sixteen Taiwanese parents of 11 children aged 1 month to 18 years were interviewed. Interviews were recorded, transcribed, analyzed and sorted into themes by the sole interviewer plus other researchers. Results: Three major themes were identified: (a) “convincing points to sign”, (b) “feelings immediately after signing”, and (c) “postsigning relief or regret”. Feelings following signing the DNR form were mixed and included “frustration”, “guilt”, and “conflicting hope”. Parents adjusted their attitudes to thoughts such as “I have done my best,” and “the child’s life is beyond my control.” Some parents whose child had died before the time of the interview expressed among other things “regret not having enough time to be with and talk to my child”. Conclusion: Open family visiting hours plus staff sensitivity and communication skills training are needed. To help parents with this difficult signing process, nurses and other professionals in the pediatric intensive care unit need education on initiating the conversation, guiding the parents in expressing their fears, and providing continuing support to parents and children throughout the child’s end of life process.

The tiger population that once inhabited the Korean peninsula was initially considered a unique subspecies (Panthera tigris coreensis), distinct from the Amur tiger of the Russian Far East (P. t. altaica). However, in the following decades, the population of P. t. coreensis was classified as P. t. altaica and hence forth the two populations have been considered the same subspecies. From an ecological point of view, the classification of the Korean tiger population as P. t. altaica is a plausible conclusion. Historically, there were no major dispersal barriers between the Korean peninsula and the habitat of Amur tigers in Far Eastern Russia and northeastern China that might prevent gene flow, especially for a large carnivore with long-distance dispersal abilities. However, there has yet to be a genetic study to confirm the subspecific status of the Korean tiger. Bone samples from four tigers originally caught in the Korean peninsula were collected from two museums in Japan and the United States. Eight mitochondrial gene fragments were sequenced and compared to previously published tiger subspecies' mtDNA sequences to assess the phylogenetic relationship of the Korean tiger. Three individuals shared an identical haplotype with the Amur tigers. One specimen grouped with Malayan tigers, perhaps due to misidentification or mislabeling of the sample. Our results support the conclusion that the Korean tiger should be classified as P. t. altaica, which has important implications for the conservation and reintroduction of Korean tigers.

This study was conducted to investigate the farm situation about bovine leukemia virus(BLV) infection that greatly influence productivity in dairy cattle and compare the accuracy of diagnosis for BLV infection between PCR and ELISA techniques. Blood samples of 193 heads from 5 herds in Chungnam and Chungbuk area were used to analyze BLV gene and serum, and the results were obtained as follows. The amplified BLV gene in dairy cattle by PCR technique resulted in 226 bp, 596 bp and 434 bp, respectively, for gag, pol and env, which were well amplified. The infection rates of BLV virus diagnosed by PCR and ELISA techniques ranged from 80.55 to 100% and from 22.22 to 86.95%, respectively, and the infection rates among 5 herds were significantly different in both methods (P<0.05). Further, the average infection rates of 5 herds were 87.05 and 63.21%, respectively, for PCR and ELISA techniques. Kappa statistics for examining consistency of diagnosis by PCR and ELISA techniques showed 0.246, which represents low consistency. Consequently, PCR based BLV technique was considered as a corrective measure for diagnosis of BLV infection in Holstein dairy cattle.

Teachers as brokers: Bridging formal and informal learning in the 21st century

David Hung,Shu-Shing Lee,Kenneth Y.T. Lim 한국교육개발원 2012 KEDI Journal of Educational Policy Vol.9 No.1

A review of schooling practices from learners’ and teachers’ perspectives relative to 21st century goals is conducted. Although schools try to embed 21st century literacies into the curriculum, there is an overemphasis on content knowledge. The instructional orientation used in schools is inconsistent with the softer skills of 21st century literacies. Instead of embedding 21st century literacies in the already packed curricula, a proposition is made for teachers to become brokers who bridge students’ learning in classroom and informal contexts such as sports activities and social media environments. Using a case study, we posit that metacognitive brokering with learners plays a critical function in bridging formal and informal learning. To encourage learners to tinker, teachers’ roles in classrooms can be transformed from one of content sages to brokers who help learners see similarities and recontextualize learning across contexts. The brokering process bridges learning across disciplines and contexts to gradually restructure schools as interdisciplinary avenues of learning. We recognize that teachers have workload and time constraints. Thus, technologies can be a mediatory tool to help teachers engage in the brokering process.

Fang-Hsin Lee,Yung-Mei Yang,Hsiu-Hung Wang,Joh-Jong Huang,Shu-Chen Chang 한국간호과학회 2015 Asian Nursing Research Vol.9 No.2

Purpose: Intimate partner violence (IPV) is a serious public health issue among women. IPV victims usually seek help from hospitals, and emergency nurses are the frontline staff with whom the victims come into contact first. This study examined the conditions and patterns of IPV in southern Taiwan. Methods: From designated hospitals in Kaohsiung under the Department of Health Injury Assessment Clinic, data were collected on 497 women regarding their injury assessment for IPV reported to the Kaohsiung City Government. Results: Taiwanese survivors were older compared to immigrant survivors. Taiwanese survivors also had higher education levels compared to immigrant survivors. Taiwanese survivors had higher employment rate than immigrant survivors did. The time between IPV and medical help seeking was longer for divorced than married women. Conclusions: These results can facilitate understanding of the conditions and patterns of IPV in Taiwan, increase the awareness of nurses, especially the emergency nurses for the prevention of IPV, and increase professional competency for the provision of appropriate healthcare services to survivors of IPV.
