Korea's Environmental Life Cycle Assessment
The Life Cycle Assessment (LCA) as an environmental-impact assessment method is gaining increasing attention all over the world due to the urgent need for the preservation and sustainability of the environment. Commonly utilized in the environmental analysis of businesses, industries, products, and services, this assessment method promoted by the United Nations Environment Programme (UNEP)/Society of Environmental Toxicology and Chemistry (SETAC) Life Cycle Initiative, the Forum for Sustainability through Life Cycle Assessment (FSLCI), International reference Life Cycle Database System (ILCD), the European reference Life Cycle Database system (ELCD), and a host of others aims at improving environmental performance towards the achievement of economically viable, safe, and sustainable societies. In Korea, LCA has drawn much attention from both industry and academia since the mid-90s, hence this study assessed the status of environmental LCA studies as it concerns the country. The Life Cycle Assessment technique serves as an important means of identifying the environmental impact of products or services throughout their entire life cycle stages.

Probiotics for Freshwater Fish Farming
Probiotics for freshwater fish farming can be administered as single or multiple mixtures. The expected benefits of probiotics include disease prophylaxis, improved growth, and feed conversion parameters, such as the feed conversion rate (FCR) and specific growth rate (SGR).

Alpha-Emitting Radionuclides in Wild Mushrooms
Alpha-emitting radioisotopes are the most radiotoxic nuclides among all radionuclides. Especially medium- and long-living isotopes that enter the body, are hazardous metals of the greatest importance from the human life point of view. This review focuses on the most common natural and anthropogenic origin alpha-emitting radionuclides in wild mushrooms around the world. Mushrooms are considered as suitable bioindicators of environmental pollution with some metallic elements, for the reason they bioaccumulate a range of mineral ionic constituents including radioactive elements at different levels. Various species have different retain capacities of individual radionuclides. In turn, wild edible mushrooms are food products, mostly consumed regionally and also traded at an international scale. Mushrooms under pollution events situation might cause a risk to consumers due to exposure to highly radiotoxic decay particles produced by alpha emitters.

Cairn
A cairn is a man-made pile (or stack) of stones. The word cairn comes from the Scottish Gaelic: càrn [ˈkʰaːrˠn̪ˠ] (plural càirn [ˈkʰaːrˠɲ]). Cairns have been and are used for a broad variety of purposes, from prehistoric times to the present. In modern times, cairns are often erected as landmarks, a use they have had since ancient times. However, since prehistory, they have also been built and used as burial monuments; for defense and hunting; for ceremonial purposes, sometimes relating to astronomy; to locate buried items, such as caches of food or objects; and to mark trails, among other purposes. Cairns are used as trail markers in many parts of the world, in uplands, on moorland, on mountaintops, near waterways and on sea cliffs, as well as in barren deserts and tundras. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to delicately balanced sculptures and elaborate feats of megalithic engineering. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. An ancient example is the inuksuk (plural inuksuit), used by the Inuit, Inupiat, Kalaallit, Yupik, and other peoples of the Arctic region of North America. Inuksuit are found from Alaska to Greenland. This region, above the Arctic Circle, is dominated by the tundra biome and has areas with few natural landmarks.

List of Cities by Sunshine Duration
The following is a list of cities by sunshine duration. Sunshine duration is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period. An important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes into account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations.

Sustainable Supply Chain Initiatives
The supply chain initiatives can be described as a set of activities performed by the firms for smooth functioning of the holistic supply chain system with the socio-economic and environmental needs in a long term period. The traditional supply chain management (SCM) practices replaced in favor of the sustainable supply chain management (SSCM) initiatives in most of the Asian industries. Nowadays, the adoption of sustainable supply chain initiatives (SSCIs) is critical for the organization to mitigate risk, handle complexities, and business dynamics of the global outsourcing. For managing supply chains smoothly, it is the very important for industries to integrate supply chains through networks designed for achieving higher business volume. This synergistic linking of sustainable supply chain practices moves the organization towards the building of the competitive edge in the global market.

Water-Soluble Organic Aerosols
Water-soluble organic aerosols (OA) are an important component of atmospheric particulate matter and one of the key drivers that impact both climate and human health. Understanding these processes involving water-soluble OA depends on how well the chemical composition of this aerosol component is decoded. Yet, obtaining such a detailed chemical information faces several challenges, of which the complexity of the sample matrix is one of the most demanding issues. A number of different advanced multidimensional analytical techniques are available today with the potential to tackel the complex chemical nature of water-soluble OA, allowing the untargeted profilling of new chemical structures without the need for use of databases or libraries. This critical review is aimed at nonspecialists who are interested in learning more about the potential and impact of such multidimensional non-targeted analytical strategies in water-soluble OA research.

SDHI Fungicide Toxicity and Associated Adverse Outcome Pathways
Succinate dehydrogenase inhibitor (SDHI) fungicides are increasingly used in agriculture to combat molds and fungi, two major threats to both food supply and public health. However, the essential requirement for the succinate dehydrogenase (SDH) complex—the molecular target of SDHIs—in energy metabolism for almost all extant eukaryotes and the lack of species specificity of these fungicides raise concerns about their toxicity toward off-target organisms and, more generally, toward the environment.
