  • This study was conducted to evaluate the effect of plant growth inhibitors on "Penncross" creeping bentgrass in the green of golf course for increasing the summer quality. Chlormequat chloride (C) 250$\times$, 500$\times$, 1000$\times$, daminozide (D) 50$\times$, 100$\times$, 200$\times$, paclobutralzol (P) 1000$\times$, 2000$\times$, 4000$\times$, trinexpac-ethyl (T) 1000$\times$, 2000$\times$, 4000$\times$, uniconazole (U) 25$\times$, 50$\times$, 100$\times$ with three concentrations, respectively, were applied to creeping bentgrass. The leaf length, leaf width, and internode length of stolon were inhibited by all plant growth retardants applied as compared to that of control in which D-50, T-2000, and trinexpac-ethyl were the most effective among treatments on the inhibition of leaf length and internode length of stolen, respectively. Leaf thickness increased more in the treatments of C-250, D-50. T-2000 and T-4000 than any other treatments. On the other hand, shoot density which was represented by number of leaves per unit area was found to be the highest in P-2000 and P-4000 treatment. In this case, all plant growth retardants with no significant differences showed increase of 15-20% in density as compared to control. Total dry weight increment was higher in P-2000 and P-4000 while leaf dry weight increment was higher in T-4000. and U-25 and 50 than other treatments. According to the visual evaluation for the purpose of turf quality measurement, it was found that paclo-butralzol, trinexpac-ethyl and uniconazole were not suitable for green maintenance and extension because of making leaves to yellow. In conclusion, it was postulated that C-250, D-50, and T-4000 had possibility to use practically in the green area of golf course.lf course.

  • Tiller numbers per Unit area were increased as plant density heightened followed by little difference in tiller number in 110 days after transplanting(ll0DAT), this being caused by the immediate increment of tiller since' 90DAT During the growth period, the greatest number of green leaves per unit area was attained in 90DAT of both 160-density and 200-density plots, and in l00DAT of 40-, 80-, and I 20-density plots. Thus, the period to reach the maximum green leaf number with the high plant density was earlier than with the' low plant density. The increment of plant density increased the DM weight of ahoveground part and, with 40-densitytreatment. DNI weight was increased 6.1 times as much up to 110DAT as up to 7ODAT but 2 to 2.9 times with other ehe'nsity treatments. The' rate of increase in stolon length was greatest at the period between 80 and 90DAT when DM weight of stolon showed a large increment. Meanwhile, the average number of stolon was 1.7 at 70DAT but was increased up to 10 at 110DAT probably due to accelerative appeance of Ist stolon branch since 8.0DAT. DM weight of stolon was found to exceeded that of root after 90DAT Thus it was concluded that, when turfs is estahlished from sprig. it may be desirable for first mowing practice to be made at least within l00 days after planting.

  • After oil shock, the importance of renewable energy has emerged and it came to the fore again as Korean government declared the policy on low-carbon green growth. Among various renewable energies, it is generally accepted that wind power is the most practical alternative. In this paper we showed the process of producing wind speed map from Gangwon Regional Meteorological Administration's 2008 data. We mapped monthly average and maximum wind speed and compared several interpolation methods applied to the weather data. This wind speed map, which reflects Gangwon's topographical and climatic regional characteristics, is expected to be a good tool for wind farm location analysis.

  • Nowadays, many countries have strived to promote prospective industries and occupations at the national level under the global circumstances such as green growth, job creation and so on. For this reason, the decision making method for qualifications foresight which will be available for the mentioned category-prospective industry and occupation- is required for it's feasibility. Pilot surveys on future workforce demand and promotion policies on service industries which are selected as a prospective industry or occupation by government parties were conducted through this research. Based on them, available qualifications-including not only national(skill) qualification but also private qualification- which can be created for prospective industries and occupations related to green growth and job creation were predicted. On the other hand, observing the change of service industry, occupation and qualification abroad, this research attempts to present the decision making method for verifying the decision' validity on qualification in Korean service industry and related occupation. Applying multicriteria decision making, a preference was examined for checking the validity of the created qualifications by prospective service industries and occupations in both sides-experts and laypeople. Based on it's result, the research was conducted regarding a validity of new qualifications in prospective industries and occupations.

  • Tropaeolum majus, with a high decorative and food demand for vertical greening systems, has been utilized to revitalize urban agriculture. The effects of number of non-woven fabrics in a non-water environment and the adaptability of T. majus to this system were investigated. Planting ground composition of the container-type wall vertical greening system was made using non-woven fabric in one, two, three, or four layers. The results showed that the soil water content remained the highest when the non-woven fabric comprised 4 sheets. The morphological properties showed more growth with the 4 sheets than with 1, 2, and 3 sheets. In terms of physiological characteristics, chlorophyll content was mostly high in the 4 sheets, while shoot fresh weight value was in the order of 3 > 4 > 2 > 1 sheet, and root fresh weight value was in the order of 4 > 2 > 1 > 3 sheets. The dry weight of the measured values in the shoot was in the order of 4 > 3 > 2 > 1 sheet while no clear difference was found in the root of each treatment. The difference in the flowring characteristics was not different, but in evaluating the characteristics as a whole, the growth in the three layers of non-waven fabric was the best. In addition, the soil moisture contents and the growth characteristics were statistically significant as a positive correlation between the groups. Thus, greater the non-woven fabric, the higher is the adaptability of T. majus to dry stress under soil water-free conditions by maintaining soil moisture content. This showed that it represented an effective alternative as a method of vertical greening system for lower maintenance urban agriculture.

  • This study was carried out to investigate the effects of soil depth and planting density on the growth of lettuce, crown daisy, and strawberry on a rooftop condition using artificial soil as a growth media. The vegetable crops showed better growth for plant height (cm), plant width (cm), plant fresh weight (g), and Fo, Fm and Fv/m on 20cm depth soil than 10cm depth soil except strawberry. Planting density of $16/m^2$ and $64/m^2$ did not show significant differences on the growth of the crops. Soil moisture content and EC were low for 10cm depth soil in lettuce plots, whereas there was no significant differences on soil moisture and EC between two soil depth in strawberry plots. Hunter's L, a, and b values showed the leaf color of lettuce dark green on 20cm depth soil and reddish on 10cm depth soil. Results showed that soil depth suitable for crop growth on rooftop conditions was 20cm rather than 10cm. Growth response of the crops showed no significant difference between $16/m^2$ and $64/m^2$, indicating that planting density of 64 $plants/m^2$ could be practiced on rooftop conditions. Lettuce growth rapidly changed in control treatment in which leaves were not pinched out, while slowly changed in plants which leaves were periodically pinched out. In the case of control plot, it was impossible to harvest because withering of lower leaves after blossom on June 22. The plant of crown daisy in which pinching was not conducted, blossomed on June 7, and the plants were removed since its aesthetical value was lost. Strawberry seemed to be a suitable vegetable crop for rooftop conditions based on its high covering rate and extended growth period until late October. The soil depth 20cm and planting density 64 $plants/m^2$ were suitable for vegetable crops on green roof system using artificial soil.

  • In the midst of increasing interest in the environmental responsibility of companies, this study investigates how eco-friendly activities affect the creation of management performance. To this end, the effect of companies' green marketing on consumers' word-of-mouth intention, the mediating effect of brand reliability, and the moderating effect of consumers' pro-environmental behavior were verified. The results of the collected data analysis are as follows. First, companies' green marketing has a positive (+) effect on consumers' word-of-mouth intention. Second, brand reliability takes a positive (+) mediating role in the relationship between companies' green marketing and consumers' word-of-mouth intention. Third, consumers' pro-environment behavior has a moderating role between Brand Reliability and their word-of-mouth intention. Therefore, companies' eco-friendly strategies and their implementation will help enhance both brand reliability and consumers' word-of-mouth intention. By revealing the effect of companies' eco-friendly strategies and their implementation on brand reliability and consumers' word-of-mouth intention it is meaningful to analyze the relationship between green marketing and the possibility of consumers' spontaneous word-of-mouth intention. The results suggest to companies that it is necessary to establish an eco-friendly marketing strategy for sustainable growth.
