  • The objective of this paper is to present the implementation of a joint modeling system able to evaluate the propagation of the polluting agents in the marine environment. The system is composed by circulation model (Mohid) and a spectral wave model (SWAN). The results coming from the circulation model are provided as input to the SWAN simulations. Following this target the Mohid water circulation model was implemented and calibrated in the Black Sea basin. The current simulations were run for one year (2010) with a time step of 24 hours, using wind fields from ECMWF. The results concerning the current fields were introduced into SWAN, and the difference between the results of the SWAN simulations with and without the current input from Mohid was assessed. In this regard, 10 points where the significant wave height difference is higher were considered and analyzed. The conclusion of the work is that such a joint system provides more reliable results concerning the wave and current conditions in the Black Sea as it is very useful in providing the support in the case of the environmental alerts that may occur in marine environments.

  • The purpose of this study is to look into a Pilotis as a space of flow in Le Corbusier's works. The first of his principals, "pilotis" shown in "5 principals in new architecture" represents the articulated relationship between architecture and site. The study is based on the flow concept of Pilotis regarding especially its functional, environmental, and visual perspective. Le Corbusier describes his architecture as a circulation representing the modern society. The Pilotis space is often reserved for this circulation while this space is also suggested as a place for the leisure or the garden uninterrupted. So it seems to be meaningful to find out the real usage of the Pilotis space in Le Corbusier's work in order to clarify the relationship between the articulated space and its use proposed. The second question is concerning to the Pilotis space as a space of flow of the light and the air. This issue is not only related to the plastic aspects of the buildings, but also caused from the social, or environmental problematic of those days. Finally, the continuity of the regard is one of the most important characteristics derived from the raised volume by Pilotis.

  • 현재 기계굴착공법인 올케이싱, 어스 드릴, 역순환공법이 널리 활용되고 있음에도 불구하고, 시공 현장에서 발생되는 부조화로 인하여 말뚝의 품질이 저하되거나 부실시공이 빈번히 발생되고 있다. 본 연구에서는 이 문제를 줄이는 방법으로 올케이싱, 어스 드릴, 역순환공법을 중심으로 현장 콘크리트타설 말뚝 시공시 발생되는 부조화 종류별로 부조화 발생요인을 현장기술자들을 대상으로 설문조사를 수행 하였다. 그리고 설문분석결과를 토대로 부조화 종류별로 빈번히 발생되는 부조화 요인을 분석함으로서 대응방안을 제시하였다. 본 연구에서 분석된 자료는 향후 건설현장에서 기계굴착공법으로 시공될 때, 부조화를 최소화 할 수 있는 효과적인 자료가 될 것으로 사료된다.

  • This study aimed at revaluating Frank Gehry's freeform constructions. To this end, the study analyzed the way the space composition and circulation system of general constructions are connected with newly extended parts in the Art Gallery of Ontario and, based on this, comparatively analyzed freeform constructions before and after the art gallery, finding out what changes were made in the exterior and interior spaces of freeform constructions built after the art gallery. The results of the study are as follows. First, starting from extending the Art Gallery of Ontario, Gehry came to use glass instead of metal as main material of freeform constructions. In order to create the circulation connecting the existing building and the extended mass, Gehry applied continuing circulation for the first time to the gallery. Third, in addition to design motives, such as the woodblock print depicting a carp by Hiroshige, still life depicting a glass bottle by Morandi and the crease of the shawl in Vermeer's paintings, which Gehry applied to freeform constructions, the design motif which was recently acquired from Pyrenees rock was added. Fourth, the trend of mall construction appeared before and after the Art Gallery of Ontario. Finally, Gary used the shape of fish as a design motif for his work at an important turning point in his Freeform Architecture.

  • In the present work, a new freeze protection method has been proposed for a natural circulation system of solar water heater. Though electrothermal wire is popularly used for the purpose, there are freezing troubles by wire cut-off and shortage of excessive electric power consumption. In the experimental device, hot water in storage tank was used to heat the outlet pipe from the tank if the pipe surface temperature falls lower than a set point. The cold water pipe to the storage tank was installed to directly contact the hot water pipe surface temperature rose by transferred heat.

  • The aim of this work is to analyze changes in cerebral hemodynamics and intracranial pressure mediated by cerebral blood flow challenges in patients with acute heart arrest. Lumped parameter model with feedback mechanism is utilized to simulate the hemodynamics of brain blood flow in case 40 min T-PLS operation is applied to patients of cardiac arrest. Numerical solutions show that cerebral blood flow and perfusion pressure in patients of cardiac arrest are sharply recovered in the initial state of T-PLS operation.

  • Is not used by consistency transport at transport of freight nothing but is using Pallet only by pedestal when work palletized unit load or materials handling when keep simplicity receptacle which fill raw material or product in factory in our country. Therefore, pallet that is most important function of Pallet is not empled circulation to end consumer from manufacturing plant which is circulation process whole path being done and factory. It is real condition stopping only in extremely determinate part process use of warehouse back. Additionally, it is possible to figure out the flow of all the materials loaded on the RFID pallet; product, material, raw material immediately, so that epoch-making management is possible and it contributes to the reduction of logistics cost because there are little loss or outflow of pallet. The materials flow is getting speedy and inventory is decreasing in the logistics process, and also bad inventory and loss problems are prevented. As a result, not only logistics cost of company but also national logistics cost is decreased. Thus it contributes to the strength of national competitiveness.

  • 최근 농촌지역이 쇠퇴하면서 농촌사회의 중심공간이었던 전통정기시장이 점차 축소되고 상권이 붕괴되면서 존폐를 위협하고 있는 실정이다. 다양한 분야에 걸쳐 전통정기시장의 활성화를 위한 대안을 제시하고 있지만 사회적, 지리적 관점에서 이루어진 연구는 정량적으로 분석하는데 한계가 있었다. 이에 본 연구에서는 강원도의 대표적인 5일장이었던 평창 대화장을 대상으로 정량적인 분석방법인 공간구문론을 활용하여 공간구조 및 보행동선을 분석하였다. 분석결과, 전체적인 공간구조는 통합도와 명료도가 높게 나타나 방문객이 전체 공간을 인지하고 이동하기에 효율적인 구조이지만 소비를 촉진시키는 전략이 필요할 것으로 판단되었다. 또한 보행동선을 분석한 결과 시장의 중심부에 위치하거나 주요시설 주변에 분포하는 동선의 통합도가 높게 나타났다. 자연발생적으로 생겨난 전통정기시장은 단순하고 명료한 공간구조를 갖고 있다는 점에서 문제점이 있으며, 쇠퇴한 정기시장을 활성화하기 위해서는 장소성을 강화하고 방문객의 소비를 촉진하는 전략이 필요할 것으로 사료된다.
