The paper analyzed on the level of consumer member's awareness to green marketing strategies (4P's; product, price, place and promotion strategies) of Hansalim specialty shops for environmentally friendly agri-products. For the study, Hansalim-Cheonanasan members had been surveyed. Consumers purchase environmentally friendly agri-products because quality and freshness of those is good. The difference in amount of the average monthly purchase between loyal customers and disloyal customers is about 130,000 won. And customer's awareness is that the first is promotion strategy, the second product strategy, the third place strategy, the last price strategy. The average monthly purchase is related with product strategy in correlations between the 4P's each other. If Hansalim maintains a product strategy, promotes extensively and keeps their product standard, more consumers will purchase Hansalim products because the most important one of effect of green marketing strategies on consumer behavior is products. Hansalim needs to go into action to increase recognition. Some of consumers have misconcepts or don't know about the 4P's well. If Hansalim promotes positively considering interrelationship about 4P's strategies or other strategies, the consumers awareness will be changed more effectively. This study shows that balanced 4P's is better than only one superior strategy because of the correlation amomg green marketing strategies.

The massive green tide occurred every summer in the Yellow Sea since 2008, and many studies are being actively conducted to estimate the coverage of green tide through analysis of satellite imagery. However, there is no satellite images selection criterion for accurate coverage calculation of green tide. Therefore, this study aimed to find a suitable satellite image from for the comparison of the green tide coverage according to the spatial resolution of satellite image. In this study, Landsat ETM+, MODIS and GOCI images were used to coverage estimation and its spatial resolution is 30, 250 and 500 m, respectively. Green tide pixels were classified based on the NDVI algorithm, the difference of the green tide coverage was compared with threshold value. In addition, we estimate the proportion of the green tide in one pixel through the Linear Spectral Unmixing (LSU) method, and the effect of the difference of green tide ratio on the coverage calculation were evaluated. The result of green tide coverage from the calculation of the NDVI value, coverage of green tide usually overestimate with decreasing spatial resolution, maximum difference shows 1.5 times. In addition, most of the pixels were included in the group with less than 0.1 (10%) LSU value, and above 0.5 (50%) LSU value accounted for about 2% in all of three images. Even though classified as green tide from the NDVI result, it is considered to be overestimated because it is regarded as the same coverage even if green tide is not 100% filled in one pixel. Mixed-pixel problem seems to be more severe with spatial resolution decreases.

The improved Green integral equation using the Kelvin-type Green function in known free of irregular frequencies where the integral over the inner free surface integral is removed from the integral equation, resulting in an overdetermined integral equation. The solution of the overdetermined Green integral equation is shown identical with the solution of the improved Green integral equation Using the B-spline higher order panel method, the overdetermined equation is discretized in two different ways; one of the resulting linear system is square and the other is redundant. Numerical experiments show that the solutions of both are identical. Using the present methods, the exact values and higher derivatives of the potential at any place over the wetted surface of the body can be found with much fewer panels than low order panel method.

The plucking season of green tea leaves is one of the important parameters that decide their metabolic diversity, quality, and prices. The effects of plucking sghlwleasons on green tea metabolites were investigated through metabolite profiling by $^1H$ NMR spectroscopy. The orthogonal projection on latent structure-discriminant analysis (OPLS-DA) showed clear discriminations of green teas by three different grades depending on plucking seasons: Ujeon, Sejak, and Jungjak. These results suggested that the nine peak groups could be used for diagnostics for identification of high quality Ujeon grade of green tea.

Spatial green's functions for a horizontal magnetic dipole in a parallel-plate waveguide are expressed in an improved closed-form with two-level approximation of the spectral green's functions. The results evaluated by the present closed-from green's function with two-level approximation are compard with those obtained the previous closed-form green's function with one-level approximation. The present results are observed to be more acurate than the previous results over wide frequency range as well as whole spatial range. The combination of the present closed-form green's functions and the moment mehtod may help in analyzing the problem of EMP coupling through an aperture into a parallel-plat waveguide and the microstrip slot antenna with a reflector.

Green tourism is a stay-flow activity between people in urban and rural area, using a natural view, tradition, and life in agricultural area. And green tourism provides rest, recreation, and new experience fur people living in urban area as well as opportunities to increase income for people in rural area. In recently, amenity is rapidly rising as a main factor fur a regional competitiveness. Boseong county shows a typical agriculture industrial structure with a weak independent base, but has a beautiful tea fields in full seasons. Boseong county is making an effort to activate the regional economy, but the result fall short of one's expectation. Several methods to activate the green tourism of Boseong county are as follows: i) introduction of specialized theme relating Boseong green tea; ii) provision of information regarding tourist resort and development of experience-program related to green tea business; iii) establishment of a sales network of products through accommodations in private houses; iv) establishment of networks among regions to achieve systematic sales of tourist experience, accommodations in private houses, and local speciality simultaneously.

The plucking season of green tea leaves is one of the important parameters that decide their metabolic quality. Here, we performed the identification and quantity analysis of the metabolites of the green tea using NMR spectroscopy. We assigned the $^1H$ resonances for sixteen metabolites. This analysis found that four metabolites, gallic acid, quinic acid, theobromine and ECG, exhibited clear discrimination of green teas by the three different grades, Ujeon, Sejak and Jungjak. Our results suggest that these four metabolites could be used for diagnostics for quality control of green tea.

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.
