This project is mainly related to evaluation of total energy consumption of low energy house, the exterior envelope of which was wholly composed of structural insulated panels(SIP). The U-value of applied SIP was in the range of 0.189 to $0.269W/m^2{\cdot}K$ and the U-value of pair glass from 0.78 to $1.298W/m^2{\cdot}K$ was applied for window dependent to its function respectively. For comparison of total energy performance, the energy simulation for pilot house was performed to compare with the control house having insulation criteria of Korean building regulation in 2009. Based on simulation of dynamic energy performance, the pilot house saved 48.3% of annual energy consumption while the control house in 2009 consumed as 85.7GJ/y. In case of heating, the result showed that the energy saving ratio amounted to 76.7%. For $CO_2$ emission, the pilot house diminished approximately 35.4% from $6,208.4kgCO_2$ to $4,009.2kgCO_2$. In payback period to early investment, it was analyzed the pilot house took 7.8 years, when the low energy house built by other insulation method with same thermal perfusion took 11.5 years. From this result, it is considered that the SIP is more effective, economic to Green Home application.

Objectives Collaboration medicine means cooperate with western medicine and traditional korean medicine to treat the one disease. In Korea, Interest in collaboration medicine is increasing, But the number of studies is scare. Therefore we will conduct collaboration medicine study for the low back pain. Methods This study composes prospective cohort registry study. If the patients who need collaboration medicine by doctor come, we will ask regist this study. And patient select collaboration treatment group and single treatment group. Total 120 patients will recruit from collaboration pilot project hospitals. Each group patient will observed 4 weeks. Telephone research will conducted after 1 month from the last follow up. During the treatment, patients are treated usual treatment type of each medicine. Primary outcome is NRS and secondary outcomes are EQ-5D and ODI. We will analyze difference of 1 week and 4 week outcome result. Conclusions This study is the first large sample size study effect of collaboration medicine in Korea for low back pain. We check present collaboration system and improve collaboration system. Aim of this study is to find the effectiveness collaboration medicine for low back pain in the real condition. And we expect this pilot study will provide the clinical collaboration information and basis.

County는 비용과 부지소요는 최소화하면서도 증가하는 지역적 물수요에 부합되는 높은 유량에서 정수장의 성능을 최대화해야하는 필요성에 직면해있다. 개선사항을 찾아내기 위하여 시설물에 대한 상세한 성능평가가 행해졌다. 성능평가는 여과와 소독공정이 운전방식의 조정과 함께 추가시설의 건설에 의하여 개선될 수 있음을 나타내었다. Pilot test는 실험된 여러 가지 대안들 중에서 혼화, 응집, 이중 여과방식이 입자의 제거와 정수 수질에 가장 좋은 것임을 보여주었다. 소독에 대한 분석 결과는 소독방법을 교정하고 추가적인 염소접촉시간을 주는 것이 소독의 안전성을 확보함과 동시에 정수의 소독부산물 농도를 최소한으로 하고 강화되는 규제치와 부합할 수 있는 최선의 방법이 될 것이라는 것을 보이고 있다. Pilot test는 저수두 자동역세척여과지가 1차여과지(roughing filter)로서 효과적이라는 것을 보여주었다. 실험결과는 이중여과가 최종유출수의 탁도를 평균 0.1NTU이하로 감소시키며 입자의 제거율을 3 log로 증가시킴을 나타내고 있다. 정수공정 전반에서의 입자의 제거는 여러 개의 공정의 개별적 성과의 합이 아니므로 시설물들을 건설하기 전에 정수장 전체적으로 예상되는 개선정도를 수량화하기 위하여 Pilot 실험이 필요하였다. Pilot test중에 탁도보다는 입자측정이 유량, 응집제의 주입량, 및 여타 운전조건의 변화에 훨씬 민감함을 보여주었다. 이러한 점이 입자측정이 특히 저탁도 원수에서 처리공정의 성능을 나타내 주는 적절한 추가적 수질인자라는 결론을 보강하여 주었다. 물수요에 부합하기 위하여 Freedom District 정수장을 성공적으로 개선하는 데는 원수의 수질, 단위공정의 성능, 활용가능한 수리학적 수두, 현시설의 배치, 운전양태 등과 같은 기술적 사항에 대한 고려가 필요하였다. 비록 모든 사항들이 각각 일정정도의 영향을 가지고 있으나, 상기의 모든 것들이 수질에 영향을 미쳤으며 수질의 성공적인 개선은 정수장 운전의 모든 부분을 파악할 수 있는 상세한 성능평가를 통하여 가장 잘 달성될 수 있다.

Pretreatment technologies are defined as technologies that prepare or condition dredged material for subsequent, more rigorous treatment processes. The objectives of this study are to test the feasibility of treating dredged sediment using pretreatment process(hydrocyclone, sedimentation basin, and flotation), and to estimate design parameters for a pilot-plant design. The final goal of the project is to recycle the dredged sediment that is otherwise reused as construction materials.

The highly maneuverable fighter aircraft such as F-22, F-16 and F-15have the high maneuverability to maximize the combat performance, whereas the high maneuver characteristics might degrade the pilot's mission efficiency due to fatigue's increase by exposing him to the high gravity and, in the worst case, the pilot could face GLOC (Gravity-induced Loss Of Consciousness). The advanced aerospace company has applied the various technologies to improve the pilot's tolerance to the gravity acceleration, in order to prevent the pilot from entering the situation of the loss of consciousness. Especially, the Anti-G Suit(AGS) equipment to protect the pilot against the high gravity in flight could improve the mission success rate by decreasing the pilot's fatigue in the combat maneuver as well as prevent the pilot from facing GLOC. In this paper, a control algorithm is developed and verified to provide an optimal air pressure to AGS according to the gravity increase during the high performance maneuver. This result is expected, as the key technology, to contribute to the KF-X(Korean Fighter eXperimental), project in the near future.
