주장성은 5세기 후반 이후 본격적으로 구축되기 시작하는 신라 석축산성의 가장 발전된 형태라고 할 수 있다. 문무왕12년(672) 신라는 해발 500m가 넘는 남한산에 대규모 산성을 쌓고 당나라와의 전쟁에 대비하였다. 당시 신라는 이미 둘레 8km가 넘는산성을 1년도 안 되는 기간 동안 쌓을 수 있는 조직력과 기술력을 갖추고 있었다. 성돌도 주변에 있는 편마암 석재가 아니라 최소한 11km 이상 떨어진 원거리에서 운반해온 화강암 성돌을 하나 하나 옥수수알 모양으로 치밀하게 가공하여 쌓았다. 보축(保築)으로 성벽을 보강하고 사다리를 타고 올라가야 하는 현문식(懸門式) 성문을 만들었으며, 성벽 위에는 돌로 쌓은 평여장(平女墻)을 쌓았다. 당나라와의 장기전에 대비하여 성 내에는 대형 창고를 지어 많은 군량미와 병장기를 비축하였다. 길이 53m가 넘는 대형 건물에는 기와 한장의 무게가 20kg에 달하는 특대형 기와를 사용하였다. 기와 무게로 인한 엄청난 지붕의 하중을 견딜 수 있도록 돌과 흙을 교대로 판축하여 견고하게 대지를 조성하고 벽체는 두께 2m가 넘도록 하여 기둥이 받는 하중을 분산시키는 등 이 대형건물은 당대 최고 수준의 건축기술로 구축되었음이 밝혀졌다. 인조2년(1624) 조선은 청나라와의 전쟁에 대비하여 남한산성을 수축하였다. 주장성의 옛터를 따라서 성을 쌓고, 주장성 성돌을 재활용하기도 하였지만 현문식 성문을 평문식(平文式)으로 바꾸고, 12개의 암문(暗門)을 새로 만드는 등 남한산성에는 조선중기의 새로운 축성기술이 반영되었다. 병자호란 이후에는 화포공격에 대응할 수 있도록 옹성과 포루가 새롭게 구축되었으며 한봉성과 봉암성, 신남성 등의 외성(外城)이 보강되었다. 성돌의 크기도 커지고 돌로 쌓았던 여장도 벽돌과 석회(石灰)로 다시 쌓아 포탄을 맞아도 쉽게 무너지지 않는 견고한 여장을 만들었다. 이처럼 남한산성은 고대의 축성기술부터 조선시대 후기까지 각 시기 축성기술을 구체적으로 알 수 있는 우리나라 축성기술사의 교과서와 같은 유적이라고 할 수 있다.

As contemporary building construction type is getting higher and deeper,construction equipment usage is getting more, and related fatal accidents are on an increasing trend. In these days, due to the deteriorating construction business circumstance, job finding problem of equipment operator, and dumping contract, equipment lease suppliers are putin jeopardy. In high-rise building construction, especially tower crane, mobile elevated work platform and other High place operation cars among construction equipment cause many critical accidents because of drop supply of construction biding bringing out dumping contract could cause unsafe and poor construction management. Because of this, a method was drawn which could grasp the present state of construction equipment management and manage safety of the equipment more easily for accident prevention by choosing 2 kinds of Construction equipment which cause safety accident frequently among the equipment mainly used in construction site. This study suggested a method about construction equipment safety management using ‘‘smart phone’ base which could be used in safety management for construction equipment by whomever in construction site. After attachment of QR code included safety checklist, It became possible that site managers could check more efficiently by scanning with their smart phone when they inspect equipment. Moreover, by the construction interested who didn’t know what and how they have to inspect could point out unsafe condition in the early stage of equipment entering or take unsafe one out of the site by using new smart phone safety checking system is installed, it became possible that critical accident caused by construction equipment was prevented in advance.

민간업체의 기술개발의욕을 고취시킴으로써 국내 건설기술의 발전을 도모하고 국가 경쟁력을 제고하기 위하여 건설기술관리법에 의하여 건설신기술지정제도를 운영하고 있다. 해당 법에서는 신기술로 지정받은 기술에 대하여는 일정기간동안의 해당기술을 보호할 수 있도록 하고 있으며, 해당 기술의 사용자에게 기술사용료를 요구할 수 있도록 규정하고 있다. 이처럼 건설 신기술 지정제도는 특허제도와 유사한 형태로 기술을 보호, 활용할 수 있는 제도로 운영되고, 해당 기술의 설계 반영시에는 그 기술의 사용료를 일정 요율로 책정하여 운영토록하고 있다. 본 연구에서는 건설신기술 지정제도와 특허제도와의 차이점을 살펴보고, 표준 설정에서 활용되고 있는 RAND 조건과 전통적 경제학에서의 가격차별 유형을 고려하여, 건설신기술지정제도의 운영 취지에 맞는 운영 방안을 제시하고자 한다.

현재 (초)미세먼지의 주요 발생 원인이 되고 있는 질소화합물(NOx) 및 PM10, PM2.5 미세먼지 입자 제거를 위해 화물차를 비롯한 경유차에 대한 다양한 규제와 정책이 추진되고 있으나 가시적인 개선 효과가 나타나지 않아 근본적인 대책이 필요한 실정이다. 이에 관한 대책으로서 국내에서는 도로 물청소, 분진흡입, 노후 경유차 대도시 운행 제한 등을 시행하고 있으나 구체적인 저감효과에는 한계가 있어 능동적인 대응 방안을 마련이 시급한 실정이다. 또한, 도심부 도로에서 발생하는 미세먼지는 도로변을 걷는 보행자와 차량 운전자의 건강에 직접적인 영향을 주는 심각한 환경문제로 대두됨에 따라 도로변 미세먼지 저감 필요성이 증대되고 있다. 따라서, 이 연구에서는 기능성 건설재료를 활용하여 도로변 미세먼지 저감 기술 개발에 관한 실증 방안을 제시하고자 한다.

This study assesses greenhouse gas evolution from construction-material manufacturing facilities and estimates the potential reduction of these gases via the future massive sequestration of carbon dioxide. The scope of the evaluation specifically targets the global-warming potential in terms of kg-CO2 equivalent/tonnage industrial waste. Life cycle assessment (LCA) is a method to quantitatively analyze the input and output of a specific material resource during its life cycle from raw-material acquisition to final disposal as well as its environmental effect(s). LCA comprises four steps: its objective and definition of the scope, the entire life-cycle analysis list, an evaluation of its effects, and life-cycle analysis. The annual inflow of petro-ash reaches 300,000 tons, and this material is transported via screw-driving systems. The composition of the petro-ash is 1.2% volatile compounds, 6.8% fixed carbon and 92% ash contents. A total of 38,181,891 Nm3/yr of carbon dioxide is sequestrated, which is equivalent to 75,000 tons per annum and 304.5 kg/ton of petro-ash waste, with 250 kg/ton of the latter sequestrated as calcium carbonate. The final analysis on the effect of one ton of petro ash in construction materials showed 27.6 kg-CO2 eq emission. According to the final LCA analysis, only 27.6 kg-CO2 eq/ton was emitted by the petro-ash that was used in construction materials if CO2 fixation during carbonate mineralization was considered, where -250 kg-CO2 eq/ton positively contributed to the LCA. In the future, commercial-scale process modification via the realization of continuous processes and the more efficient reduction of carbon dioxide is anticipated.

We constructed marine forest to restore barren grounds which are expanding in the east coast of Korea using 2 methods of (1)seedlings transplantation method and (2)underwater floating ropes method. We transplanted 3 macroalgae species, Ecklonia cava, Undaria pinnatifida, and Saccharina. japonica to construct marine forest. Blade length of Undaria pinnatifida on underwater floating ropes was 56.70±8.69㎜ in April and grew 68.75±22.30㎜ in May and 70.75±14.36㎜ in July. Blade length of S. japonica was shown 97.95-143.00㎜ in April to June. Blade length of Ecklonia cava was 30.50±1.91㎜ in May, 41.55±1.84㎜ in August, 45.30±2.57㎜ in November, 2009 and 45.30±1.99㎜ in February, 2010. The survey on Dangsa area, Ulsan-city in January, 2009 found a total number of 15 algal species(1 brown algae, 14 red algae species) with the highest variety at 5m depth of A station and the lowest at 8m depth of A and B stations. The March survey showed a total of 24 species (1 green algae, 1 brown algae, 22 red algae species) with the highest variety of 11 at depths of 3m and 5m of B station and the lowest of 6 at 10m of B station. In May, total biomass was 3,755.4g (green algae 1.2g, brown algae 199.0g, red algae 3,555.2g). From January, 2009, we found that E. cava was dominant at the depths of 3m and 5m of A and B stations while Peyssonnelia capensis was dominant at the depth of 8m of A station. The 8m depth of B station was dominated by Acrosorium polyneurum. In May, Grateloupia lanceolata was dominant at 8m depth of A station while other depths were dominated by Phycodrys fimbriata. In June, the dominant species were G. lanceolata at the 3m depth, E. cava at the 5m and P. fimbriata at the depths of 8m and 10m of A station. Under B station, G. lanceolata was dominant at the depths of 3m and 5m while P. fimbriata was dominant at the depths of 8m and 10m.

본 연구에서는 도심지 토사재해로부터 안전한 삶과 방재환경 확보 차원에서 토사재해 발생시 인명피해를 최소화하고 도시기능을 신속하게 복구할 수 있는 통합관리시스템 및 개발될 방어기술의 성능검증 및 적용성 평가를 위한 실증단지 구축 방안에 대하여 검토하였다. 추가적으로 여러 가지 토사재해 방어기술 중 산지에서 인근 도심지의 주요건물로 유입되는 토석류를 막기 위해 토석류의 강도와 피해에 적합하게 대응할 수 있는 가변형 토석류차단벽을 설계하였다. 최근 기후변화와 관련하여 집중호우로 인한 산사태 발생 빈도가 증가하고 있으며, 도심지에서의 토사재해는 막대한 재산피해 및 사망, 실종, 부상 등 인명피해가 속출하고 있다. 피해를 방지하기 위하여 여러 방어시설물과 관련 시스템이 개발되고 있으나 연구 성과물에 대한 검증 및 관리가 부실하여 실용화가 매우 저조한 실정이다. 이로 인해 연구 결과에 대한 객관적인 성능검증과 적용성 평가의 필요성이 부각되고 있다. 본 연구는 요소기술의 적용성을 평가하기 위한 실증단지를 구축함으로 개발된 기술들의 연계-통합에 의한 통합관리시스템 개발과 실용화에 기여할 수 있을 것으로 판단된다.

Nowadays, wireless sensor network applications have been used in several important areas, such as healthcare, construction, critical infrastructure, environmental monitoring, and manufacturing. However, due to the limitation of WSNs in terms of memory, energy, computation, and scalability, efficient management of the large number of WSNs data in these areas is an important issue to deal with. There is a need for a high-performance computing and massive storage infrastructure for real-time processing and storing of the data as well as analysis of the information. In this paper, we present a technology and application of sensor cloud computing based on IoT and service to manage monitoring sensor data for the f construction design-build projects. With this IoT sensor cloud platform, the entire project participants can efficiently share information to identify and solve issues in the design build phase.

Genetic map provides basic and important informations for breeding. Therefore, genetic map construction is a essential process in plant research. Panax ginseng is one of the most famous medical plant in the world. However, genetic informations of this medical plant for breeding are not enough. Because of little informations, genetic map construction of panax ginseng provides very useful information for breeding. Using Solexa next generation sequencing (NGS) technology, we have been produced a lot of expressed sequence tags (ESTs) and whole genome sequences from Chunpoong (368 Gb) and Yunpoong (6 Gb) cultivar. To develop large amount of DNA markers and thus construct high resolution genetic map, we inspect large scale of SSR motif and putative SNP sites which can be used as dCAPs markers using produced ginseng’s sequence data. As a result, we can find a number of DNA markers that have polymorphism between Yunpoong and Chunpoong cultivar. These developed DNA markers were analyzed for F2 population of Yunpoong x Chunpoong to find markers showing Mendelian segregation ratio 1:2:1.
