본 연구는 옥상녹화에서 무기질계 인공토와 유기질계 인공토가 초본인 돌나물과 목본인 순비기나무의 생육에 미치는 영향을 살펴 봄으로써 유기질계 인공토의 효용성을 제시하고자 한다. 연구기간 은 2013년 5월에서 10월로 약 5개월이며, 식물종은 초본류에 돌나 물을, 목본류에 순비기나무를 대상으로 무기질계 인공토(Inorganic substrate=perlite, IOS), 자연토(natural soil, NS), 유기질계 인공 토Ⅰ(organic substrate=artificial compost Ⅰ, OS1), 유기질계 인공토 Ⅱ(organic substrate=artificial compost Ⅱ, OS2)로 구 성하였다. 돌나물의 초장, 줄기수, 엽수, 상대엽록소함량비는 유기 질계 인공토 Ⅰ처리구(OS1)> 자연토 처리구(NS)> 무기질계 인 공토(IOS) 순으로 높았으며, 통계적인 차이가 뚜렷하였다. 생체중 과 건물중 또한 OS1, NS, IOS 처리구 순으로 생육결과와 비교적 유사한 경향을 보였다. 순비기나무는 수고, 경경, 엽장, 엽폭은 유기 질계 인공토 Ⅱ(OS2)> 자연토 처리구(NS)> 무기질계 인공토 (IOS) 순으로 유의적으로 높았으며, 특히 유기질계 인공토 Ⅱ 처리 구에서 단기간의 실험임에도 불구하고 그 차이가 뚜렷했다. 이에 옥상녹화의 식재지반에서 무기질계 인공토의 단용처리는 식물생 육에 부정적인 영향을 미칠 수 있으므로 식물생육을 위한 적정비율 의 유기질계 인공토의 활용이 요구된다. The main objective of this study was to determine whether Sedum sarmentosum and Vitex rotundifolia growth characteristics were affected by inorganic or organic substrate in growing media, to ascertain the influence of this substrate in green roof system in woody and herb species. The experimental substrate were used with four inorganic or organic substrate(perlite; natural soil, artificial compost type Ⅰ, artificial compost type Ⅱ), then comparison evaluation of their effect on the growth of Sedum sarmentosum and Vitex rotundifolia were conducted. Sedum sarmentosum was grown in different three soil substrates(perlite, natural soil, artificial compost type Ⅰ), plant height, number of stems, leaf length, leaf width, number of leaves, chlorophyll contents, fresh weight, and dry weight were higher in artificial compost I, organic substrate treatment than those in perlite and natural soil. Also, Vitex rotundifolia was grown in three different substrates, perlite, natural soil, and artificial compost type Ⅱ, plant height, root-collar caliper, leaf length, leaf width, chlorophyll contents, fresh weight, and dry weight were higher in artificial compost Ⅱ. This provides evidence of the beneficial effects of inclusion of organic substrate for green roof growing media but highlights the fact that the responses to inclusion of organic substrate may be different for inorganic substrates or plants.

Despite countries' efforts to reduce carbon emissions, carbon emissions have increased in recent decades along with energy use, of which building energy uses account for a large proportion. Energy savings are essential as a strategy to reduce carbon emissions in existing buildings. The field experiment on the roof of a building located in Seoul was designed to measure the temperature reduction effect of green roof with rainwater storage tank to reduce cooling energy consumption in summer. The results showed that the mean mean surface temperature under the green roof was 14.77 degrees lower than that of the non-green roof from 13:00 P.M. to 15:00 P.M., which would have a great effect on reducing cooling energy. From 01:00 A.M. to 03:00 A.M., the effect was 3.36 degrees, showing that tropical nights could be improved. The temperature reduction effect due to the rainwater storage system increased by 1.45 degrees during the day and decreased by 0.63 degrees at night. The storage system can be strategically utilized to reduce carbon emissions during the week when cooling energy increases significantly.

본 연구는 조선 중기 밀양의 부호세력이었던 여주이씨 일가의 금시당 이광진 유적을 중심으로 그림, 시문, 기문등에 나타나고 있는 문화경관으로서의 특성을 파악하고자 하였다. 금시당 이광진은 사회적 혼란기였던 문정왕후의 죽음 이후 중기 벼슬을 버리고 고향으로 돌아와 응천강변의 백곡에 터를 잡고 금시당을 건립하여 별서를 경영하고자 하였는데, 그가 경영한 금시당은 숙부이자 스승인 월연 이태로부터 자연관과 효행, 산수경영 등 많은 영향을 받은 것으로 판단된다. 또한, 금시당십이경도는 이경홍이 병환으로 위중한 아버지 이광진을 위로하고자 금시당 주변의 아름다운 12경관을 그린 것으로 구전되며, 꾀꼬리봉, 용두산, 무봉사, 마암산, 월연대, 사인당 마을, 영남루, 밀양읍성, 배나무 소, 밤나무 숲, 밀양강변, 삼문동들 등 당시 여주이씨 일가가 소유하고 있었던 땅과 관아를 경관 대상으로 하여 소상팔경이나 사시팔경의 관념적인 산수화가 아닌 실경을 담고 있는 산수화이다. 금시당십이경시는 금시당십이경도에 근거하여 작성된 제화시로서 이광진의 11대손 이용구가 지은 것으로 시간과 계절 그리고 기상의 변화를 노래하였다. 시 12수 모두 칠언절구로 글자 수가 모두 28자로 이루어졌으며, 단순히 그림의 외형적인 묘사가 아닌 작자의 개성에 의해 재산출되었기 때문에 그림에서 보이는 요소들과 완전히 일치하지 않는다. 따라서 금시당십이경도는 단순히 효행의 의미뿐만 아니라 밀양의 부호세력으로서 여주이씨 일가 소유의 장원을 나타내고 있으며, 금시당십이경시는 그림을 재산출하여 특정한 명승지로 변화시켜 여주이씨 일가 소유의 영역성을보다 강화시킬 목적으로 이루어진 것으로 생각된다. This study has been examined characteristics of Yeoju Lee family, rich group at Miryang in the middle of the Joseon Dynasty, around Geumsidang(今是堂) Lee Gwang-jin remains as a cultural landscape appeared in pictures, poetry, and a strange story. Geumsidang Lee Gwang-jin returned to his old home abandoned the middle government post after the death of Moonjeong queen in socially confused stage and tried to manage an annex to a Geumsidang located in Baekgok of Eungchun riverside, and Geumsidang he managed was affected by his teacher and uncle Wolyoun Lee Tae of a view of nature, filial behavior, and nature management etc. Also, ``Painting of 12 landscapes to Geumsidang`` is landscape painting with the actual view not like the ``8 landscapes of So-Sang`` or ``8 landscapes of Sa-Si`` which is abstract landscape and Lee Gyeong-hong drew 12 landscapes of Geumsidang that includes Angbong(鶯峰: nightingale peak), Yongdu mountain(龍頭山), Mubong Buddhist temple(舞鳳寺), Maam mountain(馬巖山), Wolyeon-dae(月淵臺), Saindang village(舍人堂村), Youngnam-ru(嶺南樓), Miryang eubseong(密陽邑城), Eyeonso(梨淵沼: pear tree deep water), Yullim(栗林: chestnut tree forest), Miryang river(密陽江), Sammundong fields(沙門野), land and government office owned by Yeoju Lee family as landscape objects. ``Poems of 12 landscapes to Geumsidang`` by Lee Yong-gu 11th sons of Lee Gwang-jin was written based on ``Painting of 12 landscapes to Geumsidang``, and sang for time, season, and changes of the weather. All 12 poems are all a quatrain with seven Chinese characters in each line consisted of all 28 words, but does not match completely with shown elements in pictures because it is not a simple description of pictures but it is recreated by writer``s personality. Therefore these painting shows not only th meaning of filial behavior but also village owned by Yeoju Lee family rich group in Miryang, and these poem recreated the pictures by changing as certain scenic spot with the object of enforcing territory of Yeoju Lee family.

Thermal environment of city is getting worse due to severe urban heat island caused by climate change and urbanization. Green roof improves the urban thermal environment and save the cooling energy in buildings. This study presented a green roof combined with a storage system that stores rainwater and supplies water through a wick and evaluated the temperature reduction effect as surface temperature and amount of evapotranspiration. For about a week, the surface temperature using a infrared thermal imager and the evapotranspiration by recording change of module weight were measured at intervals of 30 minutes from sunrise to sunset. The results show that the mean surface temperature of the green roof was 15.4 degrees lower than that of the non-green roof from 12:00 P.M. to 14:00 P.M. There was no significant difference between mean surface temperature of green roof with and without storage system immediately after rain, but more than a week after rain, there was a difference with average of 2.49 degrees and maximum of 4.72 degrees. The difference in daily amount of evapotranspiration was measured to be 1.66 times on average. As drought stress increased over time, the difference in daily amount of evapotranspiration and surface temperature between with/without storage system increased simultaneously. The results of the study show a more excellent cooling effect of green roof combined with the rainwater storage system.
