Preschool principal’s curriculum leadership indicators: a Taiwan perspective

Chia-Fen Lin 서울대학교 교육연구소 2013 Asia Pacific Education Review Vol.14 No.4

The role of a principal’s curriculum leadership has become an educational issue in Taiwan’s early childhood education. This study represents a pioneering attempt in adopting a target school interview, fuzzy Delphi, and analytic hierarchy process for constructing preschool principal’s curriculum leadership indicators. Fifteen experts and practitioners were involved in the Delphi panel and a two-stage questionnaire survey was administered. The findings revealed that preschool curriculum leadership indicators could be classified as 20 implementation items in six aspects: formation of preschool vision; organization and functioning of the preschool curriculum development team; control of the preschool curriculum implementation process; improvement of teachers’ curriculum professionalism; integration of different educational resources; and assessment of preschool curriculum implementation performance. Analysis of the relative weighting of curriculum leadership indicators reveals that the most important implementation items are “Ability to analyze the preschool’s background and features to provide a basis for development of a curriculum vision,” “Ability to construct a preschool curriculum vision together with other members,” “Ability to call together teachers to jointly establish a curriculum development team,” “Ability to secure resources from inside and outside the school to provide the environment and equipment needed to meet teachers’ curriculum and teaching needs.” These indicators emphasizing organizational cooperation, entrustment, and control under the context of the new leadership in Taiwan are in line with the Western concept of distributed leadership.

Curriculum Development Program in a privately-managed public preschool in Taiwan: overcoming difficulties and establishing a process pattern

Chia-Fen Lin 서울대학교 교육연구소 2016 Asia Pacific Education Review Vol.17 No.2

Preschool curriculum reform is currently underway in Taiwan. Privately-managed public preschools (PMPPs) currently play the role of bellwethers because they stand halfway between public and private preschools, and serve as testing grounds for curriculum reforms promoted by the government. This study originated from Curriculum Development Program (CDP) which is one of Taiwan government’s policies toward PMPPs. The researcher and the research subject consisted of the expert and case school participating in this program. The main objective of this article was to discuss the course about a privately-managed public preschool how to overcome difficulties and establish a process pattern of CDP. This paper employed the qualitative research methods; it included focus group, interviews, and action research. Then, the study made use of grounded theory and conducted data analysis in the three stages of open coding, axial coding, and selective coding. Based on the results of this study, the CDP exerted a mediating effect that harmonized the tensions between external impact and internal resistance. The difficulties for the external impact of CDP included: educational policy reforms, competition in the education market, and parents’ right to choose. The internal resistance of CDP included: changes in the curriculum power structure, limitations on in-school resources, and conflicts of interest among organization members. The process pattern included: use of curriculum guidance experts and action research; integration of interested parties’ resources and organization of a specialist curriculum development team; responding to internal and external needs by establishing a compromise between school-based curriculum vision and assessment approach; harmonizing external impacts and internal resistance to complete the school-based curriculum; and cyclic reflection on and revision of action plan. This study provided practical insights and offered an integrated solution of how an assistance approach with experts’ participation can be combined with curriculum policy and academic research.

In the present study, the stabilizing effect of four different biological osmolytes on Bacillus licheniformis γ-glutamyl transpeptidase (BlGGT) was investigated. BlGGT appeared to be stable under temperatures below 40°C, but the enzyme retained less than 10% of its activity at 60°C. The tested osmolytes exhibited different degrees of effectiveness against temperature inactivation of BlGGT, and sucrose was found to be the most effective among these. The use of circular dichroism spectroscopy for studying the secondary structure of BlGGT revealed that the temperature-induced conformational change of the protein molecule could be prevented by the osmolytes. Consistently, the molecular structure of the enzyme was essentially conserved by the osmolytes at elevated temperatures as monitored by fluorescence spectroscopy. Sucrose was further observed to counteract guanidine hydrochloride (GdnHCl)- and urea-induced denaturation of BlGGT. Taken together, we observed evidently that some well-known biological osmolytes, especially sucrose, make a dominant contribution to the structural stabilization of BlGTT.

Chiang, Ting-Yu,Wang, Chao-Hui,Lin, Yu-Fen,Chou, Shu-Lan,Wang, Ching-Ting,Juang, Hsiao-Ting,Lin, Yung-Chang,Lin, Mei-Hsiang Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.8

Background: Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. Materials and Methods: This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). Results: A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (p<0.001), poor performance(p<0.001), changes in medical condition (p<0.001), timing of case manager contact (p=.026), the methods by which case manager contact patients (p<0.001) and the frequency that case managers contact patients (${\geq}10times$) (p=0.016). Conclusions: Cancer patients who refuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

Background Bupivacaine, a common local anesthetic, can cause neurotoxicity and permanent neurological disorders. Crocin has been widely reported as a potential neuroprotective agent in neural injury models. Objective The aim of this study was to investigate the role and regulatory mechanism of crocin underlying bupivacaine-induced neurotoxicity. Method Human neuroblastoma SH-SY5Y cells were treated with bupivacaine and/or crocin for 24 h, followed by detecting cell viability using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay. The effect of crocin or bupivacaine on SH-SY5Y cell proliferation was measured by Ki67 immunofluorescence assay. The levels of apoptosis-related proteins and the markers in the PI3K/Akt signaling pathway were examined using western blot analysis. The activities of caspase 3, catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) were tested using respective commercial assay kits. Flow cytometry analysis was executed for detecting SH-SY5Y cell apoptosis. Result Crocin attenuated bupivacaine-induced neurotoxicity in SH-SY5Y cells. Meanwhile, crocin inhibited SH-SY5Y cell apoptosis induced by bupivacaine via repressing the activity of caspase-3, reducing Bax expression, and elevating Bcl-2 expression. Moreover, crocin mitigated oxidative stress in SH-SY5Y cells by increasing the content of CAT, SOD, GSH-Px and reducing the content of MDA. Additionally, crocin protected against bupivacaine-induced dephosphorylation of Akt and GSK-3β. The protective effects of crocin against bupivacaine-induced neurotoxicity in SH-SY5Y cells were counteracted by the Akt inhibitor. Conclusion These results suggested that crocin may exert a neuroprotective function by promoting cell proliferation and suppressing apoptosis and oxidative stress in SH-SY5Y cells. Thus, crocin might become a promising drug for the treatment of bupivacaine-induced neurotoxicity.

Association of Single Nucleotide Polymorphisms in the Prostaglandin-endoperoxide Synthase 2 (PTGS2) and Phospholipase A₂ Group IIA (PLA2G2A) Genes with Susceptibility to Esophageal Squamous Cell Carcinoma

Liu, Fen,Wei, Wen-Qiang,Cormier, Robert T.,Zhang, Shu-Tian,Qiao, You-Lin,Li, Xin-Qing,Zhu, Sheng-Tao,Zhai, Yan-Chun,Peng, Xiao-Xia,Yan, Yu-Xiang,Wu, Li-Juan,He, Dian,He, Yan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Background: The prostaglandin-endoperoxide synthase 2 (PTGS2) and phospholipase A2 group IIA (PLA2G2A) genes encode enzymes that are involved in arachidonic acid and prostaglandin biosynthesis. Dysregulation of both genes is associated with inflammation and carcinogenesis, including esophageal squamous cell carcinoma (ESCC). We therefore hypothesized that there is an association between single nucleotide polymorphisms (SNPs) in these genes and susceptibility to ESCC. Methods: We performed a gene-wide tag SNP-based association study to examine the association of SNPs in PTGS2 and PLA2G2A with ESCC in 269 patients and 269 healthy controls from Taihangshan Mountain, Henan and Hebei Provinces, the rural area of China which has the highest incidence of esophageal cancer in the world. Thirteen tag SNPs in PLA2G2A and 4 functional SNPs in PTGS2 were selected and genotyped using a high-throughput Mass Array genotyping platform. Results: We found a modest increased risk of ESCC in subjects with the PTGS2 rs12042763 AA genotype (OR=1.23; 95% CI, 1.00-3.04) compared with genotype GG. For PLA2G2A, a decreased risk of ESCC was observed in subjects with the rs11677 CT (OR=0.51, 95%CI, 0.29-0.85) or TT genotype (OR=0.51, 95%CI, 0.17-0.96) or the T carriers (CT+TT) (OR=0.52, 95%CI, 0.31-0.85) when compared with the CC genotype. Also for PLA2G2A, rs2236771 C allele carriers were more frequent in the control group (P=0.02). Subjects with the GC (OR=0.55, 95%CI, 0.33-0.93) or CC genotype (OR=0.38, 95% CI, 0.16-0.94) or the C carriers (GC+CC) (OR=0.52, 95%CI, 0.32-0.85) showed a negative association with ESCC susceptibility. Conclusions: Our results suggest that PTGS2 and PLA2G2A gene polymorphisms may modify the risk of ESCC development.

Purpose: The purpose of this study was to compare smoking prevalence and risk factors of smoking between Korean and Korean-Chinese middle school students. Methods: Data was collected from seventh and eighth grade students from 12 schools in Korea and 6schools in China. Descriptive statistics, Chi-square test, and t test were performed. Results: For data analysis 10,002 usable surveys were utilized. The smoking prevalence was higher in Korean-Chinese students than in Korean students. Risk factors, such as father smoking, friends smoking,gender, grade, academic achievement, alcohol use, and family income were associated with current smoking, and the differences in the two samples were significant. Korean-Chinese students were more likely than Korean students to have friends who smoked and a father who smoked. Smokers had a significantly higher rate of friends smoking, father smoking, and alcohol use. Korean-Chinese male students smoking prevalence was more than three times higher than Korean students. Korean students could sense a more anti-tobacco atmosphere in their environment. Korean-Chinese students were more likely than Korean students to perceive that it was easy to buy cigarettes and to smoke cigarettes in a public computer room. Conclusion: These results highlight the differences of smoking prevalence and risk factors between Korean-Chinese students and Korean students. The findings may help health educators and researchers to better understand adolescent smoking and risk factors cross culturally and aid in the development of more effective education programs, which could lead to preventing tobacco use among these populations.

Purpose The purposes of this study were to explore postpartum stress and breast symptoms in postpartum breastfeeding of parturient mothers as well as to identify the factors influencing the breast symptoms in breastfeeding women after cesarean section delivery. Methods A cross-sectional survey was conducted. A total of 162 breastfeeding women after cesarean section delivery were recruited from five hospitals in Taiwan. Structured questionnaires were used to collect data. Results The five highest postpartum stress comes from the flabby flesh of maternal belly, the baby getting sick suddenly, interrupted sleep, insufficient breast milk, and discomfort due to breast engorgement. The most two common breast symptoms in breastfeeding encountered by subjects in this study were breast engorgement and breast hardening, whereas the least common one was nipple bloody discharge. Cesarean section women with early suckling on the operating table had more breast symptoms in postpartum breastfeeding; and the higher the postpartum stress of them, the more the breast symptoms. Conclusions Breastfeeding in a comfortable condition is a key factor of precipitating breast milk secretion,so early suckling on the operating table may result in discomfort and stress of the woman and interfere with the secretion or production of breast milk. Additionally, it is a crucial factor of the success in breastfeeding that the nursing personnel can provide women help in maintaining breast milk production and secretion, taking care of a baby, and reminding women’s families (especially their husbands) of giving their assistance, encouragement and praises to relieve women’s postpartum stress.

Jia-Fen Wu,Xiaoxiao Lin 한국과학학술지편집인협의회 2021 Science Editing Vol.8 No.1

Purpose This study analyzed the bibliometric characteristics of publications on inclusive education in the Social Science Citation Index and Science Citation Index Expanded in the Web of Science Core Collection from 1992 to 2020. Methods Terms related to “inclusive education” and “inclusion of education” were used as keywords to search for journal articles on July 3, 2020. Results There were 1,786 articles, representing 3,376 authors, in the 345 journals scanned. The United States, United Kingdom, and Australia were the three leading countries/regions in this field. In the top 12 countries, the top 15 institutions and the top 10 most-cited journals were identified by either the number of publications or the number of total citations. Core themes from the 30 most highly-cited articles were teachers’ attitudes, teachers’ self-efficacy, and the effects of inclusive education. Teachers included both pre-service and in-service teachers; students represented those with and without special educational needs. Conclusion The results indicate that the United States, United Kingdom, and Australia dominated inclusive education research, originating most of the highly-cited articles, having more prolific authors, and presenting the most-cited institutions. Furthermore, three emerging core themes from the 30 most highly-cited articles were teachers’ attitudes, teachers’ self-efficacy, and the effects of inclusive education. Frontline teachers are recommended to submit manuscripts about their teaching experiences to the most-cited journals, which have a large readership. To measure the effects of inclusive education, it is essential to formulate reliable, valid, and culture-free research instruments for future studies.
