AbstractThis article examines how people's confidence in their governments changed in the context of South Korean decentralisation. South Korea provides a unique case to answer the question because it is one of the world's most rapid modernisers and has maintained autonomous local systems across three decades of decentralisation. Analysing data from the first and fourth wave of the Asian Barometer Survey in a seemingly unrelated regression (SUR) model, we find that the trust function of the local governments correlates with the trust function of the national government in 2003 and then disappears in 2015. We understand this finding as a piece of indirect evidence that South Korean local autonomy encourages local government trust, which does not reflect merely trust in the national government. This article also discusses the need for normalisation of the National Assembly, the creation of regional political parties and the dispersion of presidential power.

This project creates a toolkit that run in ArcGIS and allows users to project where EV owners will live, work, and charge. There are three distinct modules: market analysis, workplace charging, and home charging presented in block group level. The tool can be updated by the MPO users to reflect new technologies and policies, and to be used by local planners using the web interface. DVRPC has uploaded the tool's results to an ArcGIS online interface so that interested parties may use the results in their own analyses. The researchers expect these results to be useful for electric distribution companies, businesses, developers, EV charging companies, and all levels of governments in their EV planning efforts.View the NCST Project Webpage

Plug-in electric vehicles (EVs) are quickly moving to the broader consumer market. While the home is still the primary location for recharging these vehicles, public EV charging infrastructure at workplaces, public destinations, and along travel corridors will be critical for the continued market growth of EVs. Governments will need to ensure that sufficient charging infrastructure is available at these locations to meet future demand. Researchers at the University of California, Davis Plug-In Hybrid & Electric Vehicle Research Center previously developed a planning toolbox for public charging infrastructure based on data available in California. The toolboxis a user-friendly set of modeling tools that allows planners to anticipate the future geographic distribution of EVs and the resulting optimal locations of charging infrastructure.To date, however, the tools have only been applied in California contexts with California-specific data. For this project, the UC Davis researchers adapted the toolbox to be used outside of California, collaborating with the Delaware Valley Regional Planning Commission to develop a case study for using this toolbox for EV infrastructure planning in the Greater Philadelphia region. This policy brief summarizes the findings from that research and provides policy implications.View the NCST Project Webpage

Government agencies, utilities, automakers, and charging network companies are increasingly investing in charging infrastructure to encourage the adoption of plug-in electric vehicles (PEVs), which include both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). Public infrastructure is particularly important for those without access to home charging and for vehicles with driving range limitations. However, it is difficult to quantify the optimal number and location of public chargers needed for a growing number of PEVs. Finding the answer will depend on a mix of behavioral and economic factors that drive charging demand. Much is at stake. Too little infrastructure could cause congestion at the chargers and inhibit the adoption and use of PEVs, while developing more infrastructure than is needed would create unnecessary costs. For example, Level 2 public chargers can cost up to 15 times more than Level 2 at-home chargers. Researchers at UC Davis analyzed the choice of charging infrastructure of more than 3,000 PEV commuters who had access to home, work, and public locations to understand the importance of various factors driving demand for charging infrastructure at the three locations. Key factors include the cost of charging, driver characteristics, accessibility of charging infrastructure, and vehicle characteristics.

We report substrate thermal conductivity effect on heat dissipation and lifetime improvement of organic light-emitting diodes (OLEDs). Heat dissipation behavior of top-emission OLEDs fabricated on silicon, glass, and planarized stainless steel substrates was measured by using an infrared camera. Peak temperature measured from the backside of each substrate was saturated to be 21.4, 64.5, and 40.5 °C, 180 s after the OLED was operated at luminance of 10 000 cd/m2 and 80% luminance lifetime was about 198, 31, and 96 h, respectively. Efficient heat dissipation through the highly thermally conductive substrates reduced temperature increase, resulting in much improved OLED lifetime. ; This work supported by the Korea Research Foundation Grant funded by the Korean Government (MOEHRD, Basic Research Promotion Fund) (Grant No. KRF-2008-331-D00216).

BACKGROUND: The Korean Health Insurance Review and Assessment Service (HIRA) has launched the Chronic Obstructive Pulmonary Disease (COPD) Quality Assessment Program (CQAP) since 2014. We aimed to reveal the influence of this national program on clinical outcomes and the burden of COPD in Korea. METHODS: The CQAP is conducted annually. We used healthcare claims data linked with the results of the program provided by HIRA between May 2014 and April 2017. Patients were considered to have COPD if they visited a hospital for COPD management during the assessment term. Those who visited a medical institution for COPD and were prescribed COPD medications at least twice were assessed by the CQAP (assessed subjects, AS; not-assessed subjects, NAS). CQAP evaluated the pulmonary function test conduction rate, regular visitation rate, and prescription rates of COPD medications. RESULTS: Among the 560,000 patients with COPD, about 140,000 were assessed by the CQAP annually. In both groups, the pulmonary function test conduction rate and inhaled bronchodilator prescription rate improved since 2014. Compared to the NAS group, the risk of admission and all-cause mortality rate in the AS group were significantly reduced by 21.2% and 40.7%, respectively. In patients who were assessed for 3 consecutive years, all of the above variables were high at baseline and were not improved much from implementation of CQAP. In matching analysis, we observed this improvement to be limited in the COPD quality assessment year. CONCLUSIONS: The CQAP by the health insurance bureau has improved the management protocol and prognosis of COPD.
