The purpose of this study was to investigate the effect of green dietary life recognition and low-carbon green life practice on health-related dietary habits in high school students. The subjects were 367 high school students in the Incheon area. This cross-sectional survey was conducted using a questionnaire, and data were analyzed with the SPSS 20.0 program. According to the findings, green dietary life recognition were categorized into two sub-factors: 'Eco-friendly traditional dietary life', and 'Life of consideration and thanks'. Low-carbon green life practice was 'Low-carbon green life', and health-related dietary habits were categorized into four sub-factors: 'Vegetables-oriented traditional dietary habits', 'Balanced dietary habits', 'Life practice for health', and 'Various cereals intake'. Green dietary life recognition showed a significantly positive relationship with all sub-factors of health-related dietary habits (p<0.05), whereas 'Eco-friendly traditional dietary life' had no significant effect on 'Balanced dietary habits'. Low-carbon green life practice showed a significantly positive relationship with all sub-factors of health-related dietary habits (p<0.01). Students who received green growth education showed significantly higher health-related dietary habits than those who did not (p<0.01). Girls showed significantly higher green dietary life recognitions and low-carbon green life practice than boys (p<0.01). Therefore, more green dietary life and low-carbon green life education programs targeting students are need. Voluntary activities, along with green dietary life and low-carbon green life education will help students improve their health-related dietary habits.

Moss is used as an important material in indoor landscaping as well as outdoor landscaping. Moss is vivid green during growth and excellent in ornamental value. But when temperature drops, moss stops growth, turns brown or loses its ornamental value. In the present experiment, for the purpose of classifying native mosses according to the growth response to low temperature, the temperature of the plant growth chamber was set to 15℃/5℃ (16h/8h, day/night) and 5℃ (24h) for 8 weeks using nine native moss species. Thereafter, the temperature of the plant growth chamber was set to 20℃, and then the changes of moss block area and moss color were measured. The changes of moss block area and moss color were measured using a Photoshop program, after each moss block was photographed. As a result, Atrichum undulatum (Hedw.). Beauv., Etodon luridus (Griff.) A. Jaeger, Bachythecium plumosum (Hedw.) Schimp, Plagiomnium cuspidatum (Hedw.) T.J. Kop, and Hypnum plumaeforme Wilson showed a small decrease in moss block area at low temperature, and their recovery were the fastest at 20℃. These three species had higher green values at low temperature compared to other species, and the greenness increased rapidly at 20℃. On the other hand, Atrichum undulatum (Hedw.). Beauv., Marchantia polymorpha L., and Thuidium cymbifolium (Mitt.) A. Jaeger showed the smallest block area at low temperature and the lowest recovery even at 20℃. Their green values also decreased significantly at low temperature, and maintained low green value even at 20℃. These results showed that these three moss species are sensitive to low temperature. The remaining Myuroclada maximowiczii, Plagiomnium cuspidatum, and H. erectiusculum showed moderate responses to low temperature compared to other six species of mosses.

개량조개의 인공종묘생산을 위한 유생사육의 최적 사육환경과 먹이생물의 종류에 따른 유생의 성장 및 생존을 조사하였다. 수온에 따른 유생의 성장은 $18^{\circ}C$에서 $33^{\circ}C$까지 수온이 높을수록 빨랐으며, $23^{\circ}C$ 이상에서는 사육 14일째 $230{\mu}m$ 이상 성장하였으나 $18^{\circ}C$에서는 $151.1{\mu}m$로 성장이 부진하였다. 염분별 유생사육 시 염분 30 psu에서 일간 성장은 $11.3{\mu}m$로 가장 빨랐고, 생존율도 65.8%로 가장 높았다. 개량조개 유생은 사육수 1 ml 당 10개체 이하의 밀도에서는 성장과 생존율이 양호하였으나 20개체 이상에서는 다소 성장이 늦어 유생의 사육밀도는 1 ml 당 10개체 이하가 가장 효과적이었다. 개량조개 유생의 빠른 성장과 생존율을 높일 수 있는 유생사육 최적 조건은 수온 $23^{\circ}C$, 염분 30-35 psu, 유생 수용밀도 1-10 개체/ml이었다. 유생사육 시 먹이생물은 미세조류 4종 [Isochrysis galbana, Pavlova lutheri, Isochrysis sp. (green), Chlorella ellipsoidea] 을 혼합 공급한 실험구에서 빠른 성장과 생존율을 높일 수 있으며, 먹이생물을 단일종만을 공급시 I. galbana와 Isochrysis sp. (green) 실험구에서 빠른 성장과 생존율을 높일 수 있었다. 따라서 개량조개 유생의 적정먹이는 I. galbana와 Isochrysis sp. (green)를 포함한 2종 이상을 혼합 공급하는 것이 적합할 것으로 판단된다.

River and stream are the important water supply source in our lives. Eutrophication causes excessive green algae growth including microcystis, which makes harmful to ecosystem and human health. Therefore, the water purification process to remove green algae is essential. In Korea, green algae alarm system exists depending on the concentration of green algae cells in river or stream. To maintain the growth amount under control, green algae monitoring system is being used. However, the unmanned, small and automatic monitoring system would be preferable. In this study, we developed the 3D printed device to measure the concentration of green algae cell using microfluidic droplet generator and deep learning. Deep learning network was trained by using transfer learning through pre-trained deep learning network. This newly developed microfluidic cell counter has sufficient accuracy to be possibly applicable to green algae alarm system.

Plant biomass is a huge carbon-complex that has potential as a nutrient. Therefore we extracted and separated useful materials for plant growth from tea leaf and stem. The pre-treatment process including high temperature ($200^{\circ}C$) and pressure (20-40 kgf/$cm^2$) was treated for several minutes and extracted at $120^{\circ}C$ for 30-60 minutes. After that the chemical compositions and ingredients were analyzed from that plant-nutrient. As a result of mineral contents, calcium and magnesium concentrations are higher than other minerals. Also the result of carbohydrates analyses has shown that the sugar oligomer consists of xylose(95.3%) and glucose(4.7%), and the sugar monomer consists in the order of xylose (52.7%) > manose (22.8%) > arabinose (10.8%) > galactose (10.2%) > glucose (3.5%). Before applied to field, in vitro plant growth system and formulation were examined. To evaluate the effect of the nutrients, both strawberry green-house and persimmon fields were used in this test. The treated persimmons were heavier than controls scored at 13-22%. In addition, the storage-period was extended in the treated strawberries. Interestingly in the treated strawberry, the contents of polyphenols were increased (38-57%). These results suggest that the plant-nutrient can afford to help for plant growth and storage, and it can be substituted for other commercial nutrients. In conclusion, this plant-nutrient may help to extend eco-friendly or organic farming in Hadong-gun area.

The effect of ionic osmotic potential (Ψ$\pi$), and matric potential (Ψm) in the range of -0.2 to -4.0 Mpa on mycelial growth of three species of Pleurotus (P.florida, P.ostrenatus and P.safor-caju) were determined over a range of temperature (15-3$0^{\circ}C$) on a 2% malt extract agar medium and compared with the Ψ$\pi$ effect on growth of two strains of Trichoderma green mould. With the ionic solute KCl, optimun Ψ$\pi$for growth was -0.2 MPa for P.floreda and in the range of -0.2 to -0.5 MPa, with slight growth at -3.0 MPa and with nogrowth at -4.0 MPa. Of the species of Pleurotus, P.florida grew signigicantly slower than the other two species. Growt of the species of Pleurocus was significantly slower when water potential (Ψ$\omega$) was modified matrically with polyethylene glycol (PEG) 8000 then osmotically with KCl. They were also more sensitive to changes in Ψm than Ψ$\pi$The optimum Ψm of the Pleurotus was -0.5 Ψm, with no growth below -3.0 MPa. Of the species of Pleurotus, P.florida was most sensitive and P.sajor-caju was more tolerent to lowered Ψ$\pi$,but P.sajor-caju was most sensitive to lowered Ψm. The growth rate of the Trichoderma green mould strains was much faster than that observed for the Pleurotus spp. Optimum growth for bot strains of Trichoderma was in the range of -0.2 to -0.5 MPa. Strain CNU 503 was more tolerant to water stress than strain CNU 501. Both strains were able to grow up to 30% of optimum growth at -4.0 MPa at 25-3$0^{\circ}C$.

This study investigated the effects of soil depths and soil organic fertilizer application on the growth characteristics of Spiraea bumalda 'Gold Mound' in a extensive green roof system. The treatments were 3 soil depths (10, 15 and 25 cm) and 5 soil types in mixture of artificial soil and organic fertilizer. We measured plant height, leaf width, leaf length, number of flowers, visual quality and survival rate from March to October in 2011. The growing medium of 10 cm soil depth showed the highest plant growth in $A_1$ (amended soil 100%), and the lowest plant growth in $O_1A_4$ (organic fertilizer 20% + amended soil 80%) treatment. In case of 15 cm soil depth, Spiraea bumalda 'Gold Mound' showed a high leaf length and visual quality in $O_1A_2$(organic fertilizer 33% + amended soil 67%) treatment and high leaf width and number of flowers in $O_1$ (organic fertilizer 100%) treatment. $A_1$ treatment without organic fertilizer showed the lowest leaf length and poorest visual quality, and $O_1A_4$ treatment showed the lowest plant height and lowest number of flowers. At soil depth 25 cm, $O_1A_1$ (organic fertilizer 50% + amended soil 50%) treatment showed greater plant height, visual quality and number of flowers than other treatments. The leaf length and leaf width were more effective in $O_1$ treatment. $A_1$ treatment showed a relatively low leaf length, leaf width and visual quality. The higher the organic conditioner, the better the plant growth. And, survival rates of Spiraea bumalda 'Gold Mound' showed 92%, 88% and 76% at soil depths of 25 cm, 15 cm and 10 cm, respectively, in this a extensive green roof system. Therefore, the results showed that the growth of Spiraea bumalda 'Gold Mound' was affected by both soil quality and soil depth. Different optimal mixtures of organic fertilizer and amended soil were determined, depending upon soil depth.
