The Korean environmental impact assessment(EIA) system, and explored ways to improve it as a more efficient and viable institution relevant to the demand of our time and conditions in study. The first problem this study identified is found in the fact that the party to write up the assessment report is itself the business operator or the one who is planning to work out the business plan. This structure translates into placing an order with an agent for EIA report. The reporting job may br subcontracted to the agent at a cost far below the rate specified in the 'Standard for Estimate of Agency Fee for Environmental Impact Assessment.' This practice also causes the vicious circle of producing a report that is written to justify the project or business in question or it leads to rough-and ready and poor documentation to minimize the time required. Second, in order to achieve the goal of the plan or business, which is the target of EIA, the local residents tend to ve regarded as an obstacle. This means elimination of the local people from participating in the EIA or their opinion being frequently ignored. This is the seed of distrust and hostility that sometimes provoke disagreements or fierce conflicts. The first proposal to improve these problem is to improve the factors that cause poor documentation of the assessment report as well as improve the understanding of the EIA system. This study proposes the following measures for improvement. The agency cost for EIA should be paid by the business operator or a third party that can ensure faithful implementation of the payment. A system should be established to verify transparent estimation of the agency cost. In order to enhance the professional quality of EIA agents, there should be implementation of qualification test for industrial engineer of related engineers in addition to the current EIA Qualification Test. The second proposal for improvement is to improve the citizen participation process by instituting a legal framework to make clear the purpose of the briefing session for local residents, which is held as a procedure of EIA, and to ensure more positive publicity during the stage of listening to the opinion of the local community. For a smooth and rational communication process, a moderator and a communicator of opinion, as is the case in a public hearing, could be instituted to clearly get the purpose of the briefing session across to the residents and to help to carry out the explanation and Q & A sessions according to the categories of the opinion of the residents. At present, the notification of the public inspection of the draft of the assessment report and briefing session for the residents is made on the newspaper and internet network. But some people have difficulty with access to this method of announcement. A higher participation rate could be secured if a legal provision is added to specify putting up placards in specific places such as the entrance to the place for the briefing session for residents or the building of administrative agencies of the area concerned.

Vertical farming systems offer many advantages in urban spaces. They have also been proposed as an engineering solution to increase the productivity per unit area of cultivated land by extending crop production in the vertical dimension. However, soil water retention is a major constraint affecting the plant environment. This study analyzed the effects of growth environment of Tropaeolum majus and Fragaria spp., on the vertical farming system, by using four different types of cover material types including sphagnum moss (Control), a shading net (S.N.), multi-layered fabric (M.L.F.), and non-woven fabric (N.W.F.). The volumetric soil moisture contents and plant characteristics were investigated from May to September 2014. Plant materials were individually cultivated in hanging baskets measuring 30×17×17 cm, filled with a mixture of soil and perlite, and placed at 1.5m height. Each treatment was performed in quadruplicate and consisted of five plants, amounting to a total of 20 plants. The analysis indicated that different covers were associated with multiple functions and soil water retention improvements may have a positive impact on the vertical farming system. The difference in soil water retention increased in the following order: M.L.F. > Control > N.W.F. > S.N.. Furthermore, the differences in plant height and survival rate increased in the following order: M.L.F. > Control > N.W.F. > S.N. Therefore, M.L.F yielded satisfactory good response for the vertical farming system of cover materials. Our results clearly demonstrate that vertical spaces represent an attractive alternative to urban farming and suggest that further increases in yield may be achieved via different cover materials in vertical farming using hanging baskets.

The adsorption characteristics of Cu ions were studied using the zeolite Na-A synthesized from Jeju volcanic rocks. The effects of various operating parameters such as initial concentration of Cu ions, contact time, solution pH, and solution temperature were investigated in batch experiments. The adsorption of Cu ions by Na-A zeolite was fitted well by pseudo-second-order kinetics and the Langmuir isotherm model. The maximum adsorption capacity determined using the Langmuir isotherm model was 152.95 mg/g. In addition, the adsorption of Cu ions by zeolite Na-A was primarily controlled by particle diffusion model in comparison with the film diffusion model. As the temperature increased from 303 K to 323 K, ΔG˚ decreased from -2.22 kJ/mol to -3.41 kJ/mol, indicating that the adsorption of Cu ions by Na-A zeolite is spontaneous process.

In this study, a laser sheet technique and PLIF (Planar laser-induced fluorescence) are applied to a laboratory-scale pulverized coal burner of the open type, and the spatial relationship of the pulverized coal particle zone and the combustion reaction zone is examined by simultaneous measurement of Mie scattering and OH-LIF images. It is found that this technique can be used to investigate the spatial relationship of the combustion reaction zone and pulverized-coal particles in turbulent pulverized-coal flames without disturbing the combustion reaction field. In the upstream region, the combustion reaction occurs only in the periphery of the clusters where high-temperature burned gas of the methane pilot flame is entrained and oxygen supply is sufficient. In the downstream region, however, combustion reaction can be seen also within clusters of pulverized-coal particles, since the temperature of pulverized-coal particles rises, and the mixing with emitted volatile matter and ambient air is promoted.

This study aimed to estimate the effect of inoculant application level on chemical composition and bacterial count of fermented chestnut meal (FCM), and its rumen fermentation characteristics. The inoculant contained Lactobacillus acidophilus (1.2 x 1010 cfu/g), Bacillus subtilis (2.1 x 1010 cfu/g), and Saccharomyces cerevisiae (2.3 x 1010 cfu/g). The chestnut meal mixed with molasses, double distilled water, and inoculant at 1 kg, 3 g, 480 mL, and 20 mL ratio for the basal chestnut meal diet. The double distilled water from basal chestnut meal diet was substituted with bacterial inoculant at a level of 0 (Control), 20 (Medium), and 40 mL (High) in the experimental diets. The mixed experimental diets were incubated at 39℃ for 7, 14, and 21 days, respectively. On 7 days of FCM incubation, the contents of crude protein (CP) (quadratic, P=0.043) and neutral detergent fiber (quadratic, P=0.071) decreased by increases of inoculant application levels, whereas bacterial count (quadratic, P=0.065) and rumen NH3-N (linear, P=0.063) increased. By increases of inoculant application levels on 14 days of FCM incubation, the increases were found on dry matter (DM) (quadratic, P=0.085), CP (quadratic, P=0.059), acid detergent fiber (quadratic, P=0.056), in vitro DM digestibility (linear, P=0.002), rumen total volatile fatty acid (VFA) (linear, P=0.057), and rumen iso-butyrate (linear, P=0.054). However, the decreases were found on bacterial count (linear, P=0.002), propionate (linear, P=0.099), and butyrate (quadratic, P=0.082). On 21 days of FCM incubation, in vitro DM digestibility (linear, P=0.002) and total VFA (linear, P=0.001) increased by increases of inoculant application levels, whereas the contents of CP (quadratic, P=0.034) and neutral detergent fiber (quadratic, P=0.047) decreased. These results indicate that the FCM with a medium level of inoculant application and 14 of fermentation had beneficial effects by increasing DM digestibility and rumen total VFA content, without altering bacterial count.

This study was conducted to determine the effects of dietary bentonite supplementation on the fatty acid profiles of eggs in older laying hens. A total of 90 Hy-line Brown layers, 74 weeks of age, were confined in 6 wire cages and then assigned randomly to two groups to receive one of the two diets (3 replicates of 15 older layers each) containing 0 and 0.2% bentonite for 4 weeks. After the 4-week feeding trial, no remarkable differences in individual fatty acid, saturated fatty acid (SFA), unsaturated fatty acid (UFA), and mono unsaturated fatty acid (MUFA) levels were found. However, linoleic acid, docosahexaenoic acid, and poly unsaturated fatty acid (PUFA) and UFA/SFA ratio were influenced by 0.2% bentonite. In conclusion, supplementation with 0.2% bentonite improved the profiles of PUFA more than those of SFA, UFA, and MUFA inthe eggs of the older laying hens.

The influence of various forms of Houttuynia cordata with fermented red koji as feed additives on the performance of duck livestock was evaluated through a field study. Two hundred and forty ducks (Pekins) aged 0-38 d were used. They were randomly assigned to four treatment groups (0%, 1% H. cordata powder with fermented red koji, 1% H. cordata pelleted with fermented red koji, and 1% H. cordata coated with fermented red koji) with four replicates (15 ducks per replication). Foreconomic evaluation, the data (a total of 240 duck) obtained from each treatment were applied to 10,000 ducks per treatment 38-d after the feeding trial. Overall, the results of economic evaluation were the highest in the treatment with 1% H. cordata coated with fermented red koji, followed by 1% H. cordatapelleted with fermented red koji, 1% H. cordatapowder with fermented red koji, and control. In conclusion, using 1% H. cordatawith fermented red koji as coating and pellet type duck diets might be of economic advantage for sustainable environmental management.
