Purpose: G-SEED's evaluation of existing buildings in Korea is an important point because the energy consumption and CO2 emissions of existing buildings are continuously increasing due to the aging of buildings over time. In 2016, the government has set up a 'Green Remodeling Certification Standard' in G-SEED in order to revitalize the green remodeling business of existing buildings. As a result, G-SEED is distinguished between buildings with green remodeling and buildings with general remodeling. Therefore, this study analyzed the system of the certification of the green remodeling building which is aimed at improving the performance of the building. Method: First, we analyze characteristics of the existing building certification standards of G-SEED(Korea), LEED(USA), and BREEAM(UK). Second, the evaluation criteria are based on the G-SEED Green Remodeling Certification, 2016, LEED for BD + C: New construction and major renovation v.4, BREEAM UK Non-Domestic Refurbishment and Fit-out 2014. Based on the analysis results, we propose the improvement direction of G-SEED Green Remodeling Certification Standard. Result: Existing buildings should be classified into 'existing building certification' for re-certification and 'green remodeling certification' accompanied by building performance improvement. In addition, building green buildings through performance improvement should include not only energy performance, but also creating a pleasant indoor environment and minimizing environmental impact. Finally, existing buildings have accumulated information on energy and resource use, and a performance improvement plan should be established based on this information.

Urban green space is often at the centre of the debate on urban substantiality because it provides functions of space, e.g. for wildlife, recreation, growing vegetables, psychological wellbeing, social interaction, etc. Traditionally, the various functions of urban green spaces clearly show that green spaces contain important values that contribute to the overall quality of urban life. After Kyoto protocol, it has becoming important to more accurately evaluate carbon uptake by urban green space. Many studies have analyzed the benefits, costs, and carbon storage capacity associated with urban green space. These studies have been limited by a lack of research on urban tree biomass and carbon uptake by soil, such that estimates of carbon storage in urban systems. This study calculate more accurately the amount of carbon uptake by urban green space. This study also complement the existing methods to estimate the urban green space carbon uptake. It has been studied how to evaluate carbon uptake function of urban green space. The surface area of urban green space increased 5% by complemented method and carbon uptake is also increased. Based on this result, the carbon uptake per capita was analysed and compared to the area of carbon uptake. And this study discussed the reasons for the differences between the new and earlier estimates, as well as implications for our understanding of the global carbon cycle. In conclusion, these results could contribute as preliminary data to policy makers when climate change adaptation strategy is established.

Developed countries in agriculture like Netherlands, Belgium and England, have managed Green Care policy and project during the last decades. The needs in Green Care is also increasing as new growth power in rural area of Korea. This study investigated sites which are already operating as complex with Green Care theme. This study surveyed the operating conditions like type, scale, location pattern, purpose, customer and finance for cases of the complex. The period of the survey is from 2015. 8. 11 to 2015. 09. 10 for the 24 activated cases in aspect of operation and management. Among the 24 cases, 16 cases were classified as Green Care Complex which facilities are aggregated a place, and the other 8 cases as Green Care Cluster which are distributed at several places. The analysis result showed that there were apparent distinction among cases in total budget, costs of construction, capacity for guest, and the total number of annual visitors. Despite of the type and scale the accommodation cost, the number of workers, and amount of sales have small deviation in distribution of values, although the cases have various type of contents and scale of space. The result of this study can be used as data of bench marking to develop the Green Care Complex or Cluster in rural area.

The species of the genus Chlorociboria Seaver are very common on the forest floor, and can be easily distinguished by small and numerous blue-green fruitbody, especially the blue substrate dyed with xylindein produced by this group. This genus has rather high species diversity in the Southern Hemisphere, while a little attention was paid to this group in East Asia area. During a field survey in South Korea, several Chlorociboria specimens were collected. Based on morphological and phylogenetic analyses, three species of Chlorociboria were reported, including one new record in South Korea and one new record in Jeju Island. The key to the species of Chlorociboria from South Korea is provided.

This paper surveys recent remarkable progress in the study of potential theory for symmetric stable processes. It also contains new results on the two-sided estimates for Green functions Poisson kernels and Martin kernels of discontinuous symmetric $alpha$ -stable process in bounded $C^{1,1}$ open sets. The new results give ex-plicit information on how the comparing constants depend on pa-rametrer $alpha$ and consequently recover the green function and Poisson kernel estimates for Brownian motion by passing $alpha{\uparrow}2$. In addition to these new estimates this paper surveys recent progress in the study of notions of harmonicity integral representation of harmonic func-tions boundary harnack inequality conditional gauge and intrinsic ultracontractivity for symmetric stable processes. Here is a table of contents.

A very fast method of moments(MoM) for the analysis of microstrip structure is considered based upon the use of rooftop basis and razor test functions in conjunction with a new closed-form Green's functions. The present method presents a robust approach to obtain the Green's functions which can be derived by use of only one set of approximation parameters independently of operating frequency range. Moreover, using the present MoM scheme, the MoM matrix elements can be analytically evaluated with few number of terms in comparison with the previous method. So, the computational efficiency can be improved significantly without loss of the precision. In order to check the validity of the present method, performance is demonstrated for the example of a coaxially-fed microstrip transmission line and the present results are compared with the previous results.
