Green roof policies has helped to advance urban greening by creating green spaces on previously unused rooftops. However, there are no requirements covering matters such as greening methods, operation and maintenance obligations and many problems for sustainability and functioning of green roof and green space have been pointed out. This research is intended to clarify the contents and criteria of green roof policies currently implemented in Korea, Japan and other countries, compare them with the evaluation criteria for sustainable and public benefit rating systems and propose comprehensive indices for evaluating the multidimensional functions of green roof from the perspective of urban open space. As a result, it is found that obligation, grant, reimbursement, density bonus and tax credit are frequently used as green roof policies and 41 criteria including percentage of greening area, percentage of trees or shrubs, reduction of heat island effect, open space, landscape, and promotion of biodiversity are identified as criteria applicable to evaluating the multidimensional functions of green roof from the perspective of urban open space, respectively.

This study has been carried out to verify curative effect of lavender and lawn, a green space composition factor. Thus, the physiological index value of blood pressure, heart rate and salivary amylase were measured with object of 16 women in their 20~30s for stress relaxation effect at lavender garden and lawn square, and impression assessment upon SD method as for psychological value was performed in this study. And a survey was conducted on necessity and reason of urban green space with object of 345 men and women urban workers. As a result of variance analysis between groups and multi test of Turkey upon object place, the blood pressure was lowered the same at lavender garden and lawn square, and especially, high blood pressure was greatly lowered to 30 mmHG at lavender garden. On the other hand, low blood pressure group showed the tendency of a little increasing at the same places. And for the pulse, there was difference between high blood pressure group and normal group at the same places. To conclude, at lavender garden and lawn square the blood pressure was made to be lowered when it’s high, and when it’s low, the effect of returning to sound status, the function of increasing, was verified. In case of impression assessment upon SD method, the lawn square was assessed as resting place and lavender garden diversional place. And over 90% of urban workers responded to the green space’s necessity and curative effect, diversion and resting place were adopted for the reason in high-ranking items. As above the green space pattern that urban workers require and curative effect of lavender garden and lawn square were verified. Therefore, the functional green space plan is required, which curative effect, diversion and resting place are considered, for the future green space plan design.

Hydrophilic polymer is suitable as soil conditioners for green roofs that use rainwater, due to promotion of water retention capacity as well as enhancement of the water absorbing capacity. The objective of the present study was to investigate the effects of different levels of hydrophilic polymer concentrations (0, 0.1, 0.2, 0.4, 0.8% w/w) on the water holding capacity and growth response of 6 species in soils amended with hydrophilic polymer in 5 cm of soil thickness on green roofs. The results showed that the water holding capacity of the amended soil improved with increasing amount of applied polymer. The application of 0.8% w/w of the polymer increased the soil moisture by 87% compared to the control, and decreased slowly in green roofs during an arid period. The growth of Sedum spurium 'Dragon's blood' and Lampranthus spectabilis increased significantly and had greater than 60% relative coverage with higher hydrophilic polymer concentrations. However, Juniperus chinensis var. sargentii and Euonymus fortunei var. radicans had no significant differences upon change of hydrophilic polymer concentrations. In Carex kujuzana and Carex morrowii 'Aurea variegata', growth decreased with increase of hydrophilic polymer concentrations. 30 days after planting, Juniperus chinensis var. sargentii, Euonymus fortunei var. radicans, Carex kujuzana, and Carex morrowii 'Aurea variegata' died back due to lowest soil thickness (5 cm), but Sedum spurium 'Dragon's blood' and Lampranthus spectabilis had greater than 90% survival.

In recent years, the central ministries and regional self are competitively developing program for creating a trail and theme path by the increase of the number of trekkers. Even though these projects are developed in rural areas, it has been pointed out that most of projects do not directly linked to the revitalization of rural villages and improvement of non-farm income because of the main road itself as a resource in rural area. Therefore, in this study, we try to connect the citizen and the agriculture and rural area through the development of the green road which is the experience road with rural resource. To achieve this, we investigated the status and characteristics of the 36 villages where are the village was promoted various major project of first step. In second step, we considered the distinct characteristics of the area with conference of expert and site investigation for the final selection of 15 villages. Through two rounds' expert group consulting with checking, related literatures review and similar case-projects benchmarking, a riverside green road which is linked long distance trail and adjacent to the riverside was developed 15 courses by 2-development types proposed.

겨울철 작물재배를 위해서 비닐하우스 보온을 위한 수막시설의 이용이 늘어나고 있어 과다한 지하수 이용에 따른 수위 강하 및 하천수 감소를 유발하고 있다. 따라서 수막시설재배 지역에서의 지하수 양수가 지하수 대수층과 연결된 하천에 어떠한 영향을 미치는 지를 정량적으로 평가해야 할 필요가 있다. 본 연구에서는 경기도 이천시 신둔면 수하리 일대 수막시설재배지역에 지하수위와 온도를 계측하기 위한 지하수 관측공을 제내지와 제외지에 설치하고 관측 결과를 분석하여 지하수 양수에 따른 하천-지하수 상호 유동계의 변화를 평가하였다. 연구대상지역은 수위와 수온 관측 결과, 수막시설재배 기간 동안 지하수 양수의 영향으로 하천수가 지하수계로 유입되는 손실하천의 양상을 나타내었다. 하천바닥층에 대해 침윤계 실험을 통해서 유도한 수두차와 침윤량간의 관계에 자동관측된 수위자료를 대입하여 하천과 지하수계 상호간 유동량의 연속적인 변화를 산정한 결과 수막시설재배가 한창인 2월말에는 지하수 이용량의 약 16% 만큼의 하천수가 감소하는 것으로 분석되었다.

들깻잎 생산 전용품종은 대부분 만생종으로서 우량종자를 채종하고자 할 경우 도복 등이 발생하지 않아 생육관리가 용이하면서 종실 충실도가 높은 파종적기를 설정할 필요가 있다. 이에 중부지역 비닐하우스에서 잎들깨 생산 전용 품종 '잎들깨 1호'를 시험재료로 하여 5월 6일부터 7월 15일 까지 10일 간격으로 8회 파종하여 생육, 도복 발생 여부, 적산온도 및 수량성을 분석하였다. 1. 파종시기가 늦을수록 경장이 짧아지고, 주경절수, 분지수, 화방군수와 화방당 삭수는 감소되었다. 그러나 파종시기가 빠를수록 지상부 생육이 왕성하여 도복이 발생하였다. 2. 개화일수는 파종시기가 늦어질수록 직선적으로 감소되었는데 5월 6일을 기준으로 파종이 1일 지연되면 개화일수는 0.86일씩 단축되었고, 개화기부터 성숙기까지의 결실일수는 29~31일로 파종기 이동에 따른 차이가 없었다. 3. 등숙립율과 종실수량은 5월 6일 파종부터 6월 15일 파종까지 유의성이 없었고, 6월 25일 파종 이후부터 급격히 감소되었다. 4. 등숙에 필요한 적산온도, 도복 발생 여부, 등숙립율과 발아율 등으로 판단하면 만생종 잎들깨 품종의 중부지역 비닐하우스에서 파종적기는 6월 5일(정식 7월 5일)~6월 15일(정식 7월 15일)이었고, 이때 10월 28일~11월 3일경에 성숙되어 종자생산이 가능하였다. 5. 연차에 따라 0℃ 이하로 떨어지는 시기가 일찍 오는 경우 한해에 의하여 노지재배는 고사될 우려가 있고, 중부지역에서는 비닐하우스를 이용한 잎들깨 채종재배가 가능하였다.

4가지 인공배합토 모두는 용적밀도와 포장용수량을 고려할 때에 초본류를 적용한 저관리․경량형 옥상녹화뿐만 아니라 관목류를 적용한 혼합형 또는 관리․중량형 옥상녹화에도 활용 가능할 것이다. 전반적으로 시간이 경과하며 인공배합토 모두는 산성화되며 펄라이트 소립과 펄라이트 소립+일반토양(v/v, 2:1)은 적정한 수준을 나타냈고, 세라소일과 세라소일+자연토양(부피비, 2:1)은 알칼리성을 나타냈다. 펄라이트 소립과 펄라이트 소립+일반토양(v/v, 2:1)은 유기물 함량이 낮게 나타났다. 식재 후 1년이 경과한 후에 4가지 인공배합토 모두는 척박하며 건전한 생육을 저해할 것으로 판단된다. 식재 후 1년이 경과한 후에 4가지 인공배합토에서 자란 3종의 상록활엽수는 먼저 6개월이 경과한 후에서의 식물체와 비교하여 불량한 생육을 보였고, 4가지 인공배합토 상호간에도 서로 다른 생육특성을 나타냈다. 구체적으로 다정큼나무는 세라소일, 세라소일+일반토양(v/v, 2:1)에서 상대적으로 높은 생육량을 나타냈고, 남천은 4종의 인공배합토 모두에서 일반토양과 비교하여 상대적으로 낮은 생육량을 나타냈으며, 영산홍은 펄라이트, 펄라이트+일반토양(v/v, 2:1)에서 상대적으로 높은 생육량을 나타냈다. 이것은 보다 건전한 식물생육을 유도하기 위해서 각각의 상록활엽관목의 생육특성을 고려한 인공배합토의 선정이 필요함을 의미한다고 해석할 수 있으며, 또한 보다 다양한 종류의 상록활엽관목을 옥상녹화에 도입하기 위하여 각각의 인공배합토에서 그 생육특성을 평가하는 것이 필요함을 보여주고 있다.

Formation of disinfection by-products (DBPs) including trihalomethans (THMs), haloacetic acid (HAAs), haloacetonitriles (HANs) and others from chlorination of algogenic organic matter (AOM) of Microcystis sp., a blue-green algae. AOM of Microcystis sp. exhibited a high potential for DBPs formation. HAAs formation potential was higher than THMs and HANs formation potential. The percentages of dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) formation potential were 43.4% and 51.4% in the total HAAs formation potential. In the case of HANs formation potential, percentage of dichloroacetonitrile (DCAN) formation potential was 97.7%. Other DBPs were aldehydes and nitriles such as acetaldehyde, methylene chloride, isobutyronitrile, cyclobutanecarbonitrile, pentanenitrile, benzaldehyde, propanal, 2-methyl, benzyl chloride, (2-chloroethyl)-benzene, benzyl nitrile, 2-probenenitrile and hexanal.

The effects were investigated of different lengths and numbers of slitwalls in drainless containers on growth and change in soil moisture volumes on the growth of Diffenbachia amoena 'Marianne' and Begonia rex. Drainless containers filled with amended soil, with square shape (240 mm×240 mm) were used, as well as three different sets of slitwalls (2, 4 or 8, respectively) in addition to non-slitwall containers. Two indoor foliage plants were grown in slitwall containers in randomized blocks with 3 replications in greenhouse conditions, from March to September, 2009. Soil moisture volumes per container were measured by weighing containers every 2 hours during the day. The change in soil moisture volumes showed considerable differences among slitwalls tested in comparison to control containers before and after twice-weekly irrigation. Particularly, the differences in the S2 (195mm, slitwall 2) containers were significantly greater than other containers tested. For Diffenbachia amoena 'Marianne', plant height, length of leaf, dry weight and fresh weight were higher with S2 containers than with those grown in other containers tested. The Begonia rex with the best quality in terms of plant height, length of leaf and width of leaf was grown in S8 (360mm, slitwall 8) containers. Particularly, statistical analysis has indicated that shoot fresh weights of Begonia rex grown in S8 were 3-fold higher than those grown in CS8 containers. The different results obtained within the two species led us to hypothesize a species-specific influence on indoor foliage plant performance. However, plants of both species grown in slitwall containers showed good results compared with plants grown in non-slitwall containers.

Loss of leaf green color results from chlorophyll (Chl) degradation in the chloroplasts, but little is known about how Chl catabolism is tightly regulated throughout development. Using the stay-green (sgr) mutant in rice which maintains leaf greenness during senescence, we identified SGR by map-based cloning. SGR is a function-unknown gene encoding senescence-induced chloroplast protein. Transgenic rice overexpressing SGR produced yellow leaves, indicating that SGR regulates Chl degradation at the transcriptional level. Leaf stay-greenness of the sgr mutant is mainly associated with a failure in the destabilization of light-harvesting complexes (LHCs) of thylakoid membranes, which is a prerequisite event for the degradation of Chl and LHCs during leaf senescence. SGR binds to light harvesting complex of photosystem II (LHCII), but its biochemical role is so far unknown. During senescence, Chl should be degraded rapidly and safely because Chl catabolic intermediates producing ROS under light are extremely toxic to the plant cells. For safe and rapid degradation of Chl and its catabolic intermediates, Chl catabolic enzymes (CCEs) must catch the Chl intermediates effectively. In recent years, although molecular functions of SGR and CCEs have been characterized in detail, their biochemical mechanism for Chl detoxification remain elusive. Here we show that all five CCEs also specifically interact with LHCII. In addition, SGR and CCEs interact directly or indirectly with each other at LHCII, and SGR is essential for recruiting CCEs in senescing chloroplasts. These data indicate a predominant role for the SGR-CCE-LHCII protein interaction in the breakdown of LHCII-located Chl, likely to allow metabolic channeling of phototoxic Chl breakdown intermediates upstream of nontoxic pFCC.

The green rice leafhopper (GRH), Nephotettix cincticeps Uhler, is one of the most serious insect pests affecting cultivated rice (Oryza sativa L.) in temperate regions of East Asia. To understand the genetic basis of the GRH resistance, a F2 population derived from across between a highly resistant variety,Cheongnam and a susceptible variety, Junambyeo was analyzed by genetic analysis and association mapping. GRH resistance was evaluated using the F2 populations. The results showed that a single dominant gene in Cheongnam. DNA from 22 F2 individuals being either resistant or susceptible were pooled to produce bulk resistant and bulk susceptible DNA samples. Parents and bulks were screened with 192 SSR markers and twolinked SSRmarker, RM6082 and RM20145 were identified.Subsequent mapping in the original mapping population showed that thelocusis flanked by the SSR markers, RM20130 and RM20152 on chromosome 6. To physically map this locus, the-linked markers were landed on the artificial chromosome clones of the reference cv., Nipponbare, released by the International Rice Genome Sequencing Project. The DNA markers found to be closely linked to Grh3 would be useful for marker-assisted selection for the improvement of resistance to GRH in rice.

As cases of unexpected environment catastrophes drastically increased because average temperature of Earth is increased by accumulated greenhouse gases in atmosphere due to the excessive use of fossil energy, it is necessary to decrease the greenhouse gas emission in urban planning aspect. However, current researches on urban planning and design method for carbon neutrality in national level is still in early stage. This study suggested absorption method for unavoidable outbreak of carbon dioxide by deducting planning factors and estimate of absorption according to the CO2 absorption objective.

The purpose of this study was to identify the irrigation intervals and the amount of suitable growing substrate needed to achieve the desired shallow-extensive green roof system during a dry summer in Korea. In terms of treatment, three types (SL, P6P2L2, P4P4L2) with varying soil mixture ratios and two types (15 cm, 25 cm) with varying soil depths were created. The results have been analyzed after measuring growth and soil water contents. The difference of growth by treatment was significant in terms of green coverage, height, leaf width and photosynthesis. In measurement of chlorophyll content, no difference was detected when measured against soil depth. According to the growth measurement of Zoysia japonica with respect to differing soil mixture ratios in the 15 cm-deep treatment, a statistical difference was detected at the 0.05 significance level in photosynthesis. In case of green coverage, height, chlorophyll content and leaf width, no statistical significance was observed. In case of the 25 cm-deep treatment, a statistical significance was observed in height and photosynthesis. In terms of green coverage, chlorophyll content and leaf width, no statistical significance was detected. In comparisons of soil moisture tension and soil water contents, the irrigation interval and amount were 8 days and 14.9 L in the SL (15 cm) treatment, respectively. The irrigation interval showed for 10 days a 1.3-fold increase, and the irrigation amount was 27.4 L 1.8-fold more than SL (25 cm), respectively. For P6P2L2 (15 cm) treatment, the irrigation interval and amount were 12 days and 20.7 L, respectively. However, an irrigation interval under P6P2L2 (25 cm) was for 15 days 1.3 times longer than P6P2L2 (15 cm), and an irrigation amount of 40 L was 1.9 times more than that under P6P2L2 (15 cm). In P4P4L2 (15 cm) treatment, it was indicated that the irrigation interval was 15 days, and the irrigation amount was 19.2 L. It was not needed to irrigate for 16 days under P4P4L2 (25 cm) treatment during the dry summer and the longest no-rain periods. The irrigation interval and amount under P4P4L2 were 1.8-fold and 1.3-fold, respectively, more than SL treatment as affected by soil mixture ratio. Comparatively P4P4L2 had more 1.3-fold and 0.9-fold in irrigation interval and amount more than P6P2L2. Therefore, it can be noted that different soil depth and soil mixture ratios had a significant effect on the irrigation interval and amount.
