For strategic planning of municipal solid waste management, the goals and action plans should be predicted and adopted after proper evaluations of the previous achievements. Thus, this long-term plans for past and future 10 years were evaluated and developed by completing the procedures for current and future status analysis, the evaluation of the 2nd Seoul Solid Waste Management Plan (SWMP), the development of the 3rd Seoul SWMP, expert forum, public hearing, and "Prior Environmental Review" of Korea Ministry of Environment. The greatest achievements during the 2nd Seoul SWMP (2002-2011) were good performances of waste treatment methods and their rates and greenhouse gas (GHG) saving effects. The 3rd Seoul SWMP induces three policy stances and six directions of waste management from 2012 to 2021 in Seoul. The project section in this plan is divided into six policy stages and eighteen action plants in whole. The goals of the 3rd plan are direct landfill 5.4 % and resource recovery 72 % by 2021. Optimization index analysis shows the increases of the index from 62.2 % in 2009 to 79.2 % in 2021. As well as optimization index analysis, further analysis results for public budget, GHG emissions, and job creation supports that the 3rd Seoul SWMP has been successfully planned. These findings suggest several courses of action for evaluation and development of long-term solid waste management plan in various countries. © 2014 Springer Japan. Source

Emerging concern over social implications of large-scale adoption is a motivation to require certification of the sustainable origins of biofuels. In terms of the feasibility of biofuel supply in Japan, this study examines the behavioral intentions of sustainable activities by using social criteria of international levels in the context of bioethanol feedstock production in Khon Kaen, Thailand. The models adapted from the theory of planned behavior were tested by using the structural equation model. The main results are as follows: (1) In terms of the perception of working rights and conditions, which was largely influenced by the "awareness: real conditions" and "awareness: real conditions for the participants' personal lives", "personal norm" indicated the highest score. (2) "Education" had the greatest impact on solutions for personal welfare and well-being with respect to sustainable activities. (3) The scores of the importance for social welfare and well-being included six categories: reasonable compensation, reasonable working hours, healthcare and safety, fair treatment of all workers, good communication, and education with the similar ranges of scores and regression weights. (4) The "attitude toward the behavior" was the most influential predictor of "behavioral intention". Results of this investigation give an implication to design a social criteria framework in agriculture activities such as the ethanol feedstock production. © 2014 by the author(s). Source

Researchers examined difference in the abundance of mammals in post-fire silvicultural management stands within a pine forest in Samcheok, Gangwon province, South Korea, from 2008-2010. Researchers recorded the tracks of 12 mammal species, amur hedgehogs (Erinaceus amurensis), Japanese moles (Mogera wogura), raccoon dogs (Nyctereutes procyonoides), Siberian weasels (Mustela sibirica) European badgers (Meles meles), Bengal cats (Prionailurus bengalensis), wild boars (Sus scrofa), roe deer (Caproelus pygargus), water deer (Hydropotes inermis), Korean hares (Lepus coreanus), red squirrels (Sciurus vulgaris) and Siberian chipmunks (Tamias sibiricus). There were significant differences in the number of species and tracks linked to mammals among unburned, post-burned Japanese red pine planted and post-burned untreated stands. Of the 12 mammal species analyzed, six species were related to habitat variables in a stepwise approach with repeated measures. Long-term ecological research is needed to understand post-fire pine forest management. © Medwell Journals, 2012. Source

Carsharing, an alternative to car ownership, is being encouraged by many national governments as a means to alleviate air pollution and traffic congestion. Previously, many carsharing companies determined service locations through trial and error, but they currently define their parking locations in metropolitan cities for maximum customer coverage. However, identifying carsharing locations according to the experiences of the pioneering cities might not yield valid results in some Asian countries where carsharing systems are unknown. Hence, this study examines the characteristics of carsharing users in Daejeon, a small Korean city, to determine that city’s optimal carsharing service locations. A geographic information system was used to analyze and determine the best spatial areas according to two data categories: internal and external demand factors. Suitable carsharing locations were ranked by the results of a grid analysis. Thirty optimal locations were then determined from the location-allocation model in a network analysis module. Determining optimal carsharing locations should also be directly correlated with the reduction of carbon dioxide emissions. Carbon dioxide emission reduction from carsharing was predicted at 62,070 tCO2eq for the year 2013; emission reductions were predicted to increase further to 172,923 tCO2eq by 2020. Thus, carsharing is an innovative strategy for traffic demand management that can alleviate air pollution. The results of this study indicate that further research is necessary to examine the relationship between optimal carsharing locations and carbon dioxide emission reduction from using lower-emission carsharing vehicles, such as electric vehicles. © 2014, Islamic Azad University (IAU).
