Taiwan intends to be nuclear free by 2025. This study employs the Lotka-Volterra competition model for sustainable development to analyze the emissions-energy-economy (3Es) issue to make appropriate policy suggestions for a nuclear-free transition. It also offers a new approach to naming the 3E relationship. The literature review shows that the environmental Kuznets curve accompanies the feedback and conservation hypotheses. In the 3E dynamics relationship analysis, the model shows a good mean absolute percentage error (<15%) for the model estimation. The key findings are as follows: 1) the fossil fuel-led economy exists; 2) CO(2)emissions are reduced with nuclear energy consumption; 3) renewable energy is far from scale; 4) a complementary effect exists between fossil fuel and nuclear energy consumption; and 5) gas retrofitting and phasing out of nuclear seem imminent. In the energy transition, Taiwan drastically cuts nuclear energy without considering energy diversity due to which troubles might ensue. The priority issue for Taiwan's energy mix is energy security. To deal with these concerns, this study suggests the government could improve energy efficiency, build a smart grid, develop carbon capture and storage, and reconsider putting nuclear energy back into the energy mix before renewable energy is scaled.

This paper combines gravity data collected from airborne, shipborne and terrestrial surveys and those derived from satellite altimetry to determine a high-resolution gravimetric and hybrid geoid model (on a 30" x 30 '' grid) in and around Taiwan. Some 6000 new land gravity values at a 0.03-mGal precision make a notable contribution to the geoid modeling. Shipborne gravity data in waters 20 km offshore Taiwan were collected to improve the coastal geoid precision. In a circular area of 50 km around each of the five major tide gauges in Taiwan, gravity data were measured to improve vertical datum connections between Taiwan and its four offshore islands. Height anomalies were computed first and then converted to geoid heights. At > 2000 benchmarks, we obtained measured geoid heights to assess the gravimetric-only geoid and to create a hybrid geoid. Our assessments and formal errors from least-squares collocation indicate few cm of standard deviations for both geoid models, but the gravimetric geoid has mean differences of up to 20 cm with the measured geoidal heights. The hybrid geoid is used in RTK-VBS orthometric heighting, achieving a 5-cm precision. The gravimetric geoid is used to determine the relative differences in the ocean's mean dynamic topography (MDT) between Taiwan and the four offshore islands, which are also compared with those from oceanic and altimetric methods for estimating MDT. Differences in MDT help to identify 41.7 cm and 54.1 cm offsets in the current vertical datums of Penghu and Lanyu islands. In a low-lying, flood-prone region of southern Taiwan, the hybrid geoid improves LiDAR mapping of sub-zero elevation zones by 20 cm, corresponding to 70 years of sea level rise at an assumed rate of 0.286 cm/yr.

Legacy media have not managed to recoup lost revenue by pursuing digital opportunities, so the following question is worth addressing: How does the growth of digital audiences affect the brand equity of news parent brands? This study examined the feedback effects of online brands on parent brand loyalty by analyzing a survey (N = 1,199) of four national newspaper readers in Taiwan. The main results demonstrated that online brand loyalty could be transferred to parent brand loyalty, and the relationship was moderated by perceived fit. Moreover, two factors, personal-networked branding and engaging branding, contribute to the success of online brands, whereas on-demand branding might dilute the brand loyalty of an online news brand.

Background: Nationwide newborn screening for glucose-6-phosphate dehydrogenase (G6PD) deficiency has been implemented in Taiwan since 1987 and the G6PD enzyme activity levels were applied for diagnosis confirmation. As the reference value of G6PD enzyme activity was not available for infants aged 7-90 days, this study was performed to determine the enzyme level in different genotypes. Methods: Between January 1, 2016 and June 30, 2017, 410 term infants aged 7-90 days old visiting National Taiwan University Hospital Hsinchu branch were enrolled. The comparisons of G6PD enzyme activities among genotype groups were performed. Results: G6PD enzyme activity was negatively correlated with age (R = -0.212, p = 0.01). For infants under 30 days of age, the G6PD enzyme activity levels were 1.4 +/- 0.9 U/g Hb in hemizygotes (n = 76), 6.5 +/- 2.0 U/g Hb in heterozygotes (n = 47), and 13.6 +/- 3.7 U/g Hb in those without G6PD mutations (n = 70). Among infants more than 30 days old, G6PD enzyme activity levels were 0.9 +/- 0.5 U/g Hb in hemizygotes (n = 46), 6.0 +/- 2.7 U/g Hb in heterozygotes (n = 23), and 11.7 +/- 3.4 U/g Hb in those without G6PD mutations (n = 148). G6PD levels differed significantly among the groups defined by genotypes. Conclusion: We determined G6PD enzyme activity levels in infants aged between 7 and 90 days in Taiwan. Completing the reference data and determining the cutoff values for different G6PD deficiency disease statuses will help pediatricians to make accurate diagnoses.

Background Leptospirosis (LS) is a neglected tropical zoonosis of global importance. A nationwide investigation of characteristics, epidemiology, risk factors and outbreak is crucial for awareness of this disease. Methods A nationwide database of reported LS cases from October 2007 to December 2014 obtained from the Centers for Disease Control, Taiwan, was analysed. Geographic information system software was used to map the distribution of confirmed LS cases and pigs. Cross-matching with the databases of Q fever, scrub typhus and murine typhus was conducted to identify possible coinfections. Results A total of 10,917 reported cases of LS were recorded in the database, which included 665 (6.1%) confirmed LS and 10,252 (93.9%) non-confirmed LS cases. The major residences of confirmed LS were the Kaohsiung-Pingtung (248, 37.3%) and Taipei (174, 26.2%) regions. The average annual incidence was 0.4/100,000 people. Compared with non-confirmed LS cases, confirmed LS cases had significantly higher percentages of male gender (83.6% vs. 67.9%, p < .001), high-risk occupations (farmer, animal husbandry or veterinarian) (24.8% vs. 13.7%, p < .001), residence in the Kaohsiung-Pingtung region (37.3% vs. 19.6%, p < .001) and exposure to rats (8.6% vs. 4.9%, p = .001) or pigs (9.4% vs. 1.9%, p < .001) but a lower mean age (47.8 +/- 15.1 vs. 51.+/- 18.5 years old). Rat and pig exposure trends were found in the northern and southern regions, respectively. Distribution of LS was consistent with pigs, and one outbreak associated with flooding and pigs occurred in the Pingtung region in 2009. Twenty-three and four patients with LS were coinfected with scrub typhus and Q fever, respectively. Conclusions LS is an endemic disease in Taiwan, particularly in the Kaohsiung-Pingtung and Taipei regions. High-risk occupations and animal exposure history are important for the clinical presumptive diagnosis of LS, particularly for rats in northern Taiwan and pigs in southern Taiwan. Although uncommon, clinicians should be aware of coinfection of LS with endemic rickettsial diseases.

Background Information on functional strengths and weaknesses of mucopolysaccharidosis (MPS) patients is important for early intervention programs and enzyme replacement therapy (ERT). Methods We used the Functional Independence Measure for Children (WeeFIM) questionnaire to assess the functional skills of 63 Taiwanese MPS patients (median age, 13 years 3 months; range, 3-20 years) from January 2012 to December 2018. Results Mean total WeeFIM score was 75.4 of a potential score of 126. Mean total WeeFIM scores of each type (MPS I, MPS II, MPS IIIB, MPS IVA, and MPS VI) were 103.8, 76.2, 41.6, 92.2, and 113.6, respectively. Mean scores for self-care, mobility, and cognition domains were 30 (maximum 56), 23 (maximum 35), and 22 (maximum 35), respectively. MPS type IIIB patients had the lowest scores in self-care, mobility, cognition, and total domains compared to other types of MPS. All patients with ERT in MPS I, II, and IVA had higher scores in self-care and mobility domains than patients without ERT. Most patients required assistance for self-care skills, especially in grooming and bathing. Conclusion MPS patients require support and supervision in self-care tasks. For cognition tasks, MPS IIIB patients also require help. This questionnaire is useful to identify the strengths and limitations of MPS patients.

Successfully enforcing insider trading law, as well as determining the effectiveness of that enforcement, is one of the quandaries of securities law. The main reason for this perplexity is that there is no tally of how many illegal trading activities are actually taking place. To solve this problem, this study proposes to use pre-announcement price run-up as a proxy for measuring the effectiveness of an insider trading law. After examining mergers and acquisitions data from Taiwan's Financial Supervisory Commission from 2003 to 2016 and adjusting for market effect, we arrive at an average cumulative abnormal return of 6.62% before the official announcement of the events. This constitutes a 58.9% run-up compared with the post-announcement price increase. This investigation is important because it is the first to suggest an objectively empirical observation that approximates the overall size of illegal insider trading activities in a market. This method could serve as a sensitive tool for measuring temporal changes brought about by different legal arrangements within a single country or for measuring comparatively across different legal regimes.

Due to budgetary constraints, the government releases the right to ancillary business development for private investors to increase profits in PPP projects. However, the ancillary business scale is not specified in the regulations, and there is little relevant research on modeling the scale. Thus, our research aims to create a model with mathematical analysis to evaluate the ancillary business scale. The model is constructed based on the discounted cash flow model to calculate the ancillary business scale attracting private investors with a case study of a social housing project. For this case, the calculated ancillary business minimum scale (ratio of ancillary business to project in total floor area) based on the 7-year (2009-2016) and 17-year (2000-2016) data are 30.81% and 52.79%, respectively; neither is able to meet the scale listed in the tender condition regulated by the government, i.e., 25%. Moreover, this study performs a sensitivity analysis on the expected rate of return and rent discount of the case. The government needs to raise the proportion of ancillary businesses or to increase the rent of social housing to successfully attract private investors.

Taiwan launched its evidence-based health-promoting school (HPS) program via an action-research approach in 2010. The program featured a collaborative partnership between schools, local education authorities and university support networks. This study was focused on examining whether an HPS action-research approach was effective in advancing HPS implementation, perceived HPS impact and perceived HPS efficacy in Taiwan. In 2011, questionnaires were sent to 900 sample schools in Taiwan. A total of 621 schools returned the questionnaire, including 488 primary schools and 133 middle schools. The response rate was 69%. This study compared the difference in HPS implementation status, perceived HPS impact and perceived HPS efficacy between those schools that had implemented action-research HPS (138 schools) and those that had not (483 schools). The univariate analysis results indicated that the HPS implementation levels for components that included school health policies, physical environment, social environment, teaching activities and school-community relations were significantly higher in action-research schools than in non-action-research schools. Teachers in action-research schools reported significantly higher levels of HPS impact and HPS efficacy than non-action-research schools. The multivariate analysis results indicated that after controlling for school level and HPS funding, the HPS action-research approach was significantly positively related to greater levels of HPS implementation, perceived HPS impact and perceived HPS efficacy.
