The Psychomotor Vigilance Test (PVT) is a simple and reliable performance test that measures sustained attention, alertness level, and fatigue level. The PVT is a convenient tool that can be used in real time in situ through a mobile device without the assistance of experts and therefore can be used to improve safety and prevent accidents. However, the original PVT is vulnerable to the subject's intentional concentration on the test, and the variance range among tests is narrow; these factors limit its usefulness in classifying the level of fatigue.

  • South Korea decided to reach "carbon neutrality" by 2050 and is now figuring out whether to use renewable energy or nuclear power to help achieve this goal.
  • A survey with 1,000 people showed that 60.3% preferred renewable energy over nuclear power, which was only preferred by 27.7% of respondents.
  • Although more people liked renewable energy, those who liked nuclear power felt more strongly about it, and researchers analyzed the reasons behind these preferences.

EG-Mirotin (active ingredient EGT022) targets nonproliferative diabetic retinopathy (NPDR), the early stage of retinopathy. EG-Mirotin reverses capillary damage before NPDR progresses to an irreversible stage. EG-Mirotin safety and efficacy were investigated in patients with type 1 or type 2 diabetes mellitus and moderate to severe NPDR.

Aurelia aurita (AA), a legally registered harmful marine organism in South Korea, is damaging marine human leisure activities, local residents' tourism income, fisheries, and cooling water intake at power plants. The government is therefore seeking to eradicate AA by removing AA-attached larvae (polyps). This article looks into the public willingness to pay (WTP) for the eradication, utilizing a contingent valuation.

Background/purpose: Because complete microbial elimination of the infected root canal system is nearly impossible to achieve, the use of root canal fillings with antibacterial effects may help to minimize intracanal infections. Our previous study, MTA modified by CaF addition, improved the biocompatibility and mineralization potential of human dental pulp cells without adverse effect on the physical properties. In this study, the antibacterial effect of MTA after CaF addition was evaluated for use as a root canal sealer.

Air pollution is an important global issue, and governments are making efforts to reduce air pollutant emissions. The elaborate calculation of the social costs of air pollution is essential for justifying the substantial public expenditure on air pollution control policies. This study aims to derive the monetary value of reducing different kinds of air pollutants through the public's willingness to pay (WTP).

  • - The South Korean government is investigating the environmental conservation value (ECV) of the endangered plant Cypripedium japonicum, listed as a priority species by the Ministry of Environment and on the International Union for Conservation of Nature’s Red List.
  • - A survey conducted in May 2020 with 1,000 participants determined that the average household is willing to pay approximately KRW 3,770 (USD 3.07) annually for its conservation, totaling about KRW 76.72 billion (USD 62.42 million) nationally.
  • - Since the estimated ECV of the plant appears to exceed the costs of conservation, the paper concludes that preserving Cypripedium japonicum is socially beneficial and recommends ongoing conservation

Background/purpose: Glass ionomers undergo degradation when exposed to fluoride, which changes the physico-chemical characteristics of the materials. The purpose of this study was to evaluate the surface changes of resin-modified glass ionomer (RMGI) when immersed in a sodium fluoride (NaF) solution according to pH and time.

Materials And Methods: 120 RMGI specimens were prepared, and 30 specimens were placed in four types of storage solutions for four weeks; pH 7 artificial saliva with or without 0.

South Korea is pursuing an energy transition policy (ETP) of expanding the use of renewable energy and natural gas and decreasing that of nuclear energy and coal in total generation. An investigation of whether the public is for or against the ETP is needed by the government. This article explores the public preference toward the ETP employing the data collected through a survey of 1000 individuals.

  • The South Korean Government is considering making Jaran Bay a marine protected area to help the endangered Neophocaena asiaeorientalis species, but they need to assess public support and economic benefits first.
  • A nationwide survey of 1,000 households was conducted to determine how much people are willing to pay (WTP) for the designation, using a specific questioning method about annual income tax contributions.
  • The average WTP per household was estimated at KRW 2,665 (about USD 2.27), leading to a potential national value of KRW 53 billion (USD 45.3 million), but over 64% of respondents indicated they would not pay anything, showing challenges in gaining public consensus.

Onshore wind farms have the advantage of a lower cost than offshore wind farms, but their negative environmental impact has been pointed out as a problem. If this environmental impact can be lessened, public acceptance of onshore wind farms will be significantly increased. This study investigates public attitudes to the lessening of the environmental impact of onshore wind farms, focusing on three specific attributes: visual impact, ecosystem destruction and noise pollution.

Combined heat and power (CHP), which produces both heat and electricity at the same time, is so efficient that it can reduce energy use and emit less carbon dioxide (CO) than conventional fossil fuel use. This article attempts to look empirically into the impact of CHP share in total electricity generation on CO emissions in a cross-country context. Data from 35 countries during the period 2009-2015 are used.
