A subway station is a prominent multi-purpose facility where the quantitative management of fine dust, generated by various factors, is conducted. Recently, eco-friendly air purification methods using air-purifying plants are being discussed, with the focus on biofiltration through vegetation. Previous research in this field has confirmed the reduction effects of transition metals such as Fe, which have been identified as harmful to human health. This study aimed to identify the sources of fine dust dispersion within subway stations and derive an efficient operational strategy for air-purifying plants that takes into account the behavior characteristics of fine dust within multi-purpose facilities. The experiment monitored regional fine dust levels through IAQ stations established based on prior research. Also, the data was analyzed through time-series and correlation analyses by linking it with passenger counts at subway stations and the frequency of train stops. Furthermore, to consider energy efficiency, we conducted component-specific power consumption monitoring. Through this study, we were able to derive the optimal operational strategy for air-purifying plants based on time-series comprehensive analysis data and confirm significant energy efficiency.

The guideline of selection of Integrated Management Practices (IMPs), such as wood, green roof, lawn, and porous pavement, for Low Impact Development (LID) design was proposed by ranking the reduction rate of surface runoff using LIDMOD1.0. Based on the guideline, LID was designed with several scenarios at two apartment complexes located at Songpa-gu, Seoul, Korea, and the effect of LID on surface runoff was evaluated during last 10 years. The effect of runoff reduction of IMP by land use change was highly dependent on the kind of hydrologic soil group. The wood planting is the best IMPs for reduction of surfac runoff for all hydrologic soil groups. Lawn planting is an excellent IMP for hydrologic soil group A, but reduction rate is low where soil doesn't effectively drains precipitation. The green roof shows constant reduction rate of surface runoff because it is not influenced by hydrologic soil group. Compared to the rate of other IMPs, the green roof is less effect the surface runoff reduction for hydrologic soil group A and is more effect for hydrologic soil group C and D followed to planing wood. The porous pavement for the impervious area is IMPs which is last selected for LID design because of the lowest reduction rate for all hydrologic soil group. As a result of LID application at study areas, we could conclude that the first step of the strategy of LID design at apartment complex is precuring pervious land as many area as possible, second step is selecting the kind of plant as more interception and evapotranspiration as possible, last step is replacing impervious land with porous pavement.

Sustainable consumption is the consumer's preference for the products that are environmentally friendly however, non-consumption also plays a major role in sustainability. A counter movement of anti-consumption runs from the beginning of mass-consumption of societies. Consumers can choose not to consume products/brands that can cause a harm to the environment or are incompatible with their ideology on conservation. The underlying notion of these non-consumption practices or anti-consumption is that the consumer is concerned about the effects that a purchasing choice has, not only on themselves but also on the external world. Anti-consumption is a resistance to, distaste of or even resentment of consumption. There is low adaptation rate of green consumption in terms of household products which shows that the non-green consumers reflect the mainstream population and indicates that consumers following anti-consumption is a niche segment reflecting the need of research in this area. So it is consequential to explore the available literatures regarding the subject matter and conduct a quantitative study. Following the notion this paper aims analyzing the factors influencing the anti-consumption behavior of household products in Nepalese context.

In this paper, a new green clustering algorithm is proposed to be as a first approach in the framework of an energy efficient strategy for centralized enterprise high-density WLANs. Traditionally, in order to maintain the network coverage, all the APs within the WLAN have to be powered-on. Nevertheless, the new algorithm can power-off a large proportion of APs while the coverage is maintained as its always-on counterpart. The two main components of the new approach are the faster procedure based on K-means and the more accurate procedure based on Evolutionary Algorithm (EA), respectively. The two procedures are processes in parallel for different designed requirements and there is information interaction in between. In order to implement the new algorithm, EA is applied to handle the optimization of multiple objectives. Moreover, we adapt the method for selection and recombination, and then introduce a new operator for mutation. This paper also presents simulations in scenarios modeled with ray-tracing method and FDTD technique, and the results show that about 67% to 90% of energy consumption can be saved while it is able to maintain the original network coverage during periods when few users are online or the traffic load is low.

This study investigates consumers' purchasing behavior and perception of the low-carbon certificated agricultural product. To this end, we surveyed 1,000 consumers and the main findings are as follows. First, Even after six years of national certification, it is important to promote the low-carbon certification system due to insufficient awareness and purchase experience. Second, the certificated area is small at around 5% of the area of environment-friendly agricultural products and GAP certification, and certification is concentrated on fruit trees. Third, an appropriate level of high-priced strategy can be useful considering the cost of low-carbon certification, image management of low-carbon certificated agricultural products, and quality is the most important factor for consumers to consider when purchasing fresh agricultural products. Fourth, consumers recognized that the contribution of low carbon certification in reducing greenhouse gas emissions and preserving the environment was higher than that of environment-friendly agricultural products or GAP certification. Considering that, promotional activities linked to environment-friendly agricultural products and GAP certification may be effective when promoting low-carbon certification. Finally, the Ministry of Agriculture, Food and Rural Affairs is implementing a carbon point system linked to Green Card to revitalize low carbon certification, but 25.7% of consumers are aware of it, and 8.4% have little experience in issuing it.

Green Standard for Energy and Environmental Design(G-SEED) has been used for environmental friendly building certification since 2002. The certification criteria initialed with multi-residential building and now it expands to 10 criteria for new and existing building types. The purpose of this study is to understand current recognition of G-SEED from the survey of multi-complex residences in newtown. From the general question, 75.2% of responders answered the period of living term between 1~3 years, 58.6% lived in $102.48{\sim}132.23m^2$ residential area and 65.2% owned their residences. The 43.2% of respondents recognized that their residences gained G-SEED certification by G-SEED emblem(31.6%). This is the significant meaning to understand public recognition of G-SEED and how to approach the strategy for raising the G-SEED recognition. The responders expected positive influence for economical value from G-SEED and also 75.3% of responders agreed with that G-SEED would be a decision make to buy and rent their residences. Second, residents responded that the consideration issue for green building is energy & prevention of environmental pollution(27.7%) which carries equal concern in G-SEED criteria category. The result of this survey verifies that the current level recognition of G-SEED of the responder's perspectives still is not well-known but it confirmed they have a positive expectation. Therefore, from this result, G-SEED needs to draw road map with detail plans for developing G-SEED with public participation.

The purpose of this study is to identify landscaping costs for apartment landscapes, landscape facility factors, and the transition of spatial composition for landscapes. In addition, based on the questionnaires and analysis results for workers in related fields such as landscape design companies and construction companies, this study aimed at acquiring results for the development of current apartment landscapes and directions for improvement in the future. Through the results, it aimed at providing basic data for apartment landscapes in the future. Results showed that there was approximately a 2.6 times increase for landscaping expenses of actual apartment landscapes, and a 7.0 to 11.5 times increase in the future can be expected. The cause of such increase is the continuously growing demand for a more pleasant environment. Landscape facilities factors have been diversified, and most facilities are used as multi-purpose spaces rather than serving simple facilities. Questionnaires and field investigations showed that water facilities underwent the biggest changes, and the cause for such changes were found to be the introduction of new facilities such as water facilities and environmental structures, as well as the creation of integrated functions and spaces. Spatial composition for landscapes showed that multi-purpose spaces were established, and for the apartment differentiation strategy, there were many different changes such as theming of green areas and places for exchange among residents. For changes, the most changes were in green areas, and studies also showed that there were many changes for rest areas as well. The cause for such change is judged to have been brought about by the increase of landscape space by placing parking areas underground, and investigations showed that compared to green areas composed of large grass patches, recent apartments are establishing diverse and experience-based green areas.
