This study is intended to estimate the demand for the green health industry market, to seek for the strategies to develop human resources and to provide fundamental data for development of local green health industry specialization programs in the manner of investigating the intentions to participate in and opinions about the green health industry. Data were collected from 190 and surveyed from 5 to 19 in November 2010. Based upon the priority survey and factor analyses of educational contents for development of human resources specializing in the green health industry, there is some difference in the classification of all domains between the two groups, however the results concerning the cognition of the language education of educational contents and the priority of medical tourism marketing are similar between the two groups. As one of the biggest problems with medical tourism is the difficulty of communication during medical examination and treatment, it is desirable to develop professional human resources with global competitiveness based on customized education as well as excellent language skills by the specialized fields of green health industry.

Global warming affects water supply and water resources throughout the world. In many countries, climate change affects significantly on the fresh water resources. Vietnam is exposed mainly, to landslides and floods triggered by tropical storms and monsoon rains, although storm surge, whirlwind, river bank and coastal line erosion, hail rain. In addition to the prevalent drought, there are many major water challenges, including water availability, stress, scarcity and accessibility, because of poor resource management. Fast growth of urbanization, industrialization and population growth, agricultural activities and climate change cause heavy pressure on water quality. Both domestic and industrial wastewater, as well as storm water shares the same drainage. The common facilities for wastewater treatment are not available. Therefore, wastewater is treated only superficially and then discharged directly into rivers and lakes causing serious pollution of surface water environment. In this paper, we reported the severe water crisis and massive green algal blooms formation in Vietnam rivers and lakes. This is the biggest evidence of climate change variations in Vietnam.

In this study, soybean pods of 45 soybean landraces (or varieties) were classified as yellow (19 samples), black (23 samples), or black in green (3 samples) based on soybean seed coat color. Total polyphenol and flavonoid contents were measured, and antioxidant, anti-inflammatory, anti-obesity, and estrogen-like activities were assessed. Total polyphenol and flavonoid content ranges were 24.13-108.03 mg GAE/g and 3.31-72.02 mg CE/g, respectively, and were highest in the black group followed by the yellow group and were least in the black in green group, while ABTS and DPPH activities followed the order black in green > black > yellow. Estrogen-like and estrogen receptor-α activity ranges were 29.06-35.58 pg/mL and 7.05-10.13 pg/mL and were followed the order yellow > black > black in green and black in green > yellow > black, respectively. Nitric oxide (NO) inhibitory and UCP-1 activities followed the same order as estrogen receptor-α activities. Our findings suggest that soybean pods are excellent sources of antioxidants and high-quality functional materials.

Rapid urbanization has taken environmental toll on the surrounding which can be witnessed by the advent of global warming and climate change. Driven by environmental needs, Green Building Index (GBI) was established in Malaysia to drive initiative to lead the property industry towards becoming more environmental friendly. Green roofs (roof with vegetated cover) as one of the assessment criteria of GBI, are gaining attention in the Malaysian society as a versatile new environmental friendly mitigation technology. This paper evaluates the qualitative and quantitative performances of an extensive green roof at Humid Tropics Centre under local tropical climate. Simulations showed that the extensive green roof system could reduce the peak discharge up to 26% in relation to impervious brown roof. Its reduction ability decreased for storms with intense rainfall. Increment of pH was observed for the green roof runoff and the runoff water quality ranged between class I and II under Water Quality Index (WQI). High concentrations of phosphate were noticed in the runoff samples and substrates (fertilized planting soil) might be the potential contributor. Findings indicate that there was a reduction of around $1.5^{\circ}C$ for indoor temperature of the building after installation of the extensive green roof.

The significance of high-quality development and green total factor productivity has attracted widespread attention and research, while few studies on green total factor productivity that considers the use of water resources have been conducted in the context of water shortages and water stress. In this study, the green total factor productivity of water use from 2005 to 2015 in mainland China is evaluated based on the global Malmquist-Luenberger productivity index. Results show that: (1) China's green total factor productivity of water use has been improving since 2005 with an annual global Malmquist-Luenberger productivity index of 1.0104. (2) At the regional level, the eastern zone in mainland China owns the highest green total factor productivity of water use, while that in the intermediate zone ranks last. (3) The green total factor productivity of water use in the southern region (1.0113) significantly higher than that in the northern region (1.0095), and also higher than the national average level in the same period. BPC index has been the most important incluencing factor of green total factor productivity of water use at both national level and regional level since 2011.

Climate change has recently become a serious global issue, and carbon emissions and energy consumption are increasing, particularly in cities where economic activities and populations are concentrated. Accordingly, various countries worldwide are promoting the Green New Deal and promoting urban-centered climate change response policies with the aim of carbon neutrality. In Korea, following the "smart green city" project that creates a city where humans and the environment coexist, a similar "carbon neutral green city" policy is set to be introduced. Therefore, in this study, implications and directions for the sustainable introduction of the carbon neutral green city policy will be derived by comparing and analyzing the State and Tribal Assistance Grants of the U.S. bipartisan infrastructure law and the smart green city of the Korean new deal.

This study was carried out to investigate the changes of plant species and soil physicochemical properties on green roofs established at Seoul Women's University in 2005, 2006 and 2007. The plant species and soil properties were investigated in 2013. The areas of green roof sites ranged $90{\sim}100m^2$. There were floras of vascular plants of 12 families, 20 genera and 22 species in the 2005 site, 24 families, 37 genera and 38 species in the 2006 site, 14 families, 27 genera and 31 species in the 2007 site. The total number of plant species decreased in the 2005 and 2006 sites and increased in the 2007 site since established. High proportion of dispersal type was barochory in the 2005 and 2006 site, and autochory in the 2007 site. And the proportion of the compositae family was high in the introduced plants over the sites for the all study sites. Average pH and organic matter concentration of green roof soil were ranged from 5.25 to 5.96 and 7.17 to 8.96% in study sites. The organic matter concentration and pH of green roof soil were lower in 2013 than in the three establishment years. Carbon concentration of green roof soil in the three study sites were ranged from 4.16 to 5.30% and total soil carbon in 10cm depth were ranged form 1.57 to $1.98kg/m^2$.

Nowadays, stormwaters have been affected by urbanization and climate change. These transition can cause many problems for hydrologic cycle by increasing runoff volume like flood and low water quality. As with other metropolises and peninsulas, Busan has involved with these problems too. Therefore, it is really vital to do some arrangements to solve them by low impact development (LID) technology. In fact, LID has been introduced to reduce runoff by applying some techniques such as green infrastructure (GI). In order to deal with the aforementioned issues in Busan, this study attempts to design and construct a hybrid green roof-planter box system at Pusan National University GI/LID Facility based on local weather. For this purpose, we used experiment and modeling method on some planter boxes and optimized them by trial and error method.

The aqueous Green tea comes to be used with the Oriental medicine plant, it has the numerous health benefits, including antioxidant, anti-inflammatory, and anti- carcinogenic properties. Epidermal progenitor cells give rise to multiple skin lineages: hair follicle, sebaceous gland and the overlying interfollicular epidermis. Sebocytes are the cells of the sebaceous gland, which synthesize and accumulate lipid dropolets. In order to determine the effect of Green tea on lipid production, several experiments were performed in SZ95 cells (sebocytes). We found that Green tea increased lipid droplets compared with control in a dose-dependent manner. Human sebaceous glands produce sebum, a lipid mixture of squalene, wax esters, triglycerides, cholesterol esters, and free fatty acids that is secreted onto the skin. Therefore, to investigate the effects of Green tea on intracellular lipid levels, we treated SZ95 cells with Green tea, and then examined cholesterol and triglyceride levels. After treatment of the cells with Green tea, the cholesterol and triglyceride levels of SZ95 cells were increased significantly in a dose-dependent manner.
