The International Hurricane Research Center (IHRC) at Florida International University (FIU) is pursuing research to better understand hurricane-induced effects on residential buildings and other structures through full-scale aerodynamic and destructive testing. The full-scale 6-fan Wall of Wind (WoW) testing apparatus, measuring 4.9 m tall by 7.3 m wide, is capable of generating hurricane-force winds. To achieve windstorm simulation capabilities it is necessary to reproduce mean and turbulence characteristics of hurricane wind flows. Without devices and methods developed to achieve target wind flows, the full-scale WoW simulations were found to be unsatisfactory. To develop such devices and methods efficiently, a small-scale (1:8) model of the WoW was built, for which simulation devices were easier and faster to install and change, and running costs were greatly reduced. The application of such devices, and the use of quasiperiodic fluctuating waveforms to run the WoW fan engines, were found to greatly influence and improve the turbulence characteristics of the 1:8 scale WoW flow. Reasonable reproductions of wind flows with specified characteristics were then achieved by applying to the full-scale WoW the devices and methods found to be effective for the 1:8 scale WoW model.

The purpose of this study was to investigate how student felt the strengths and shortness of presentation methods for formation of interior spaces. For this study, the process of the interior architecture design class was divided into three stages: the programming. the design development, and the design completion. In the design development stage, students used presentation methods: hand sketch, scale model, computer modeling, and virtual realty. The strengths of hand sketch was that quick expression. Models provided three-dimensional feelings. Computer modelling provide realistic color and texture. Virtual reality provided three-dimensional immersion and real scale. It is effective that students collect brain storm images using quick hand sketch in the beginning of design development stage. After that, they compose interior spaces in study models with small scale. Watching the models, they design details of spaces by using hand sketch and computer modelling. Using virtual reality, they can check the scale and circulation. Finally, they complete computer modelling by texture mapping and check the final design in virtual reality.

Simulation is performed to analyze the characteristics of turbulent spray combustion in a diesel engine condition. An extended Conditional Moment Closure (CMC) model is employed to resolve coupling between chemistry and turbulence. Relevant time and length scales and dimensionless numbers are estimated at the tip and the mid spray region during spray development and combustion. The liquid volume fractions are small enough to support validity of droplets assumed as point sources in two-phase flow. The mean scalar dissipation rates (SDR) are lower than the extinction limit to show flame stability throughout the combustion period. The Kolmogorov scales remain relatively constant, while the integral scales increase with decay of turbulence. The chemical time scale decreases abruptly to a small value as ignition occurs with subsequent heat release. The Da and Ka show opposite trends due to variation in the chemical time scale. More work is in progress to identify the spray combustion regimes.

요 지 : 본 연구에서는 먼저 우리나라 해역별 해양환경 특성이 담긴 장기 파랑 관측자료로부터 Goda 모형을 활용하여 파력과 양력 시계열자료를 생성하였다. 이어 이렇게 생성된 시계열자료부터 Three-parameter Weibull distribution에 기반한 파력과 양력 확률모형을 개발하였다. 해역별로 다른 우리나라 해양환경은 파력과 양력 확률모형 모수에서도 그 차이를 확연하게 드러내었다. 충분히 발달한 풍성 파가 우월한 남해안의 경우 큰 Scale Coefficient, 작은 Location Coefficient, 1.3 전후의 Shape Coefficient로 특정되는 것을 확인하였다. 이에 비해 파랑의 성장이 취송거리에 의해 제한되는 서해를 마주하고 있는 군산의 경우 작은 Scale Coefficient, 큰 Location Coefficient, 2.0 전후의 Shape Coefficient로 특정되었다. 서해와 남해가 만나는 해역을 마주하고 있는 목포의 경우 작은 Scale Coefficient, 큰 Location Coefficient, 제일 작은 Shape Coefficient를 지녀 남해와 서해의 해양환경이 혼재한다는 사실도 확인할 수 있었다.

This study is concerned with the identification of the concepts and characteristics of the traditional access of small scale fishery and traditional small scale fishery based on the classification of fisheries under Fisheries Law, As we called, these fisheries are the small scale of artisanal fisheries. These traditional small scale of artisanal fisheries have been developed throughout the most coastal fisheries but have never been included the institutional fishery system and policy since industrial fisheries have been exploited. By this reason there was no studies to understand and identify these fisheries as fisheries under category of institutional fishery system. Recently by the Fisheries Law, my Person who desires to operate these fisheries, shall report to the provincial governor and then these fisheries were incorporated into the category of fisheries to be reported. But this case of the administrative practices should be not consistent with the classification of fisheries under Fisheries Law. The traditional access of small scale fishery is a derivative concept of fishery categories under the institutional fakery system Because this fishery under institutional fishery system can not be establish the right of fishing by fishery right system technically but the right of fishing is supported by the fishing access system only. Therefore, It is a mistake for the provincial fishery governor to adopt such a policy that the fishing right of the traditional access of small scale fishery which is different from the fishing based right is restricted by the factors of fisheries to be reported. On the other hand the traditional small scale fishery is coincident with the traditional access of small scale fishery and the common fishery under the style of utilization of fishing gear and fishing gear and methods. But this fishery has never been included the fishery categories supported by the government subsidy policies and considerations and has been remained with indifference during the last few decades. Anyhow the fishing right of these fisheries have been assured under the institutional fishery system, any person who desires to operate this fishery should have a fishing right against the public or private uses of fishing ground such as land reclamations and other coastal zone development. A deprivation of the fishing right of this fishery by the conflicts of these public and private uses of fishing ground is not regarded as appropriate according to the social welfare policy. Also it is the administrative expediency to support the fishing right of this fishery under the fisheries lobe reported.

This study examined the regulation status on wastewater treatment in agro-food processing and a case study on effluent treatment m ethods was carried out to evaluate any change after the mitigation of regulation. First, in order to clarify the area of investigation, the definition of small-scale agro-processing facilities was reviewed through literature survey and local government ordinance. The current law were separately analyzed into four areas; effluent treatment facilities, development of agro-processing industries, land use and food processes equipment. The exclusion clauses on wastewater discharging facility in the enforcement regulation were defined in detail, which can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, was carried out. As the result, this survey confirmed the positive effects of the deregulation on promoting sewer system service in rural areas, introducing the new processing construction and so on. In addition, it was found that some matters to be considered to determine whether to introduce wastewater treatment plan for public food processing facilities.
