Today, 55% of the world’s population lives in urban areas, a proportion that is expected to increase to 68% by 2050.

The relationship between body mass index (BMI) and mortality remains controversial. Furthermore, the association between BMI and cardiovascular events (CVE) is not conclusive and may differ by ethnicity. We aimed to estimate the associations between the BMI and mortality or cardiovascular disease in a general Korean population.

The purpose of this issue brief is to provide an overview of the latest movement of the emissions trading scheme (ETS), with a focus on the three key Asian carbon markets in Tokyo, China (esp. the pilots) and the Republic of Korea (hereinafter abbreviated as Korea).

This study proposes the new hydrological drought index, Korean Surface Water Supply Index (KSWSI), which overcomes some of the limitations in the calculation of previous SWSI applied in Korea and conducts the probabilistic drought forecasts using KSWSI. In this study, all hydrometeorological variables in the Geum River basin were investigated and appropriate variables were selected as KSWSI components for each sub-basin. And whereby only the normal distributions are applied to all drought components, probability distributions suitable for each KSWSI component were estimated.

Backward trajectories of individual Asian dust storm (ADS) events were calculated using the hybrid single particle Lagrangian integrated trajectory (HYSPLIT) at four representative stations in Korea. A total of 743 ADS events and associated 2229 (endings of altitudes at 1000 m, 1500 m, and 2000 m per ADS event) backward trajectories from four stations were traced from January 2003 to August 2015. Regardless of the locations of the observed stations and the threshold time divide, recent increase of ADS occurrence rate was statistically significant in 99.9 % confidence limit.

The west coast of Korean Peninsula is an area where casualties and property damages by meteo-tsunamis from the Yellow Sea have been reported. A case in point is the event with an estimated maximum amplitude of 240 cm in Yeonggwang (YG) on 31 March 2007. Many studies have been carried out since then in Korea. These researches focused primarily on the oceanographic aspects (e.g., the resonance between the atmosphere and ocean). They wanted to calculate the resonance effects by the propagation velocity and direction of meteo-tsunami.

As the effects of climate change set in, and population and income growth exert increasing pressure on natural resources, food security is becoming a pressing challenge for countries worldwide.

Reintroduction of the threatened red-crowned crane has been unsuccessful. Although gut microbiota correlates with host health, there is little information on gut microbiota of cranes under different conservation strategies. The study examined effects of captivity, artificial breeding and life stage on gut microbiota of red-crown cranes. The gut microbiotas of wild, captive adolescent, captive adult, artificially bred adolescent and artificially bred adult cranes were characterized by next-generation sequencing of 16S rRNA gene amplicons.

According to the OECD report, air pollution is also likely to cost around $2.6 trillion annually, in terms of sick days, medical bills and reduced agricultural output globally.

This study, different from the past researches, has been conducted in all age groups to understand the association between air pollutants, pollen risk indexes, and outpatients with allergic rhinitis (AR), asthma, and atopic dermatitis (AD).
