  • 한국산 담수어류인 버들치(Moroco)속의 동버들개(M. percnums)는 한반도 이북에 서식하며 이남지역에는 분포하지 않는 것으로 보고되어 있었으나 본 형태연구 결과와 유전적 연구(Yang and Min, 1989) 결과, 강원도 강릉 경포호지역에서 동버들개가 서식 분포하는 것이 확인되어, 동버들개의 분포상 최남단 지역으로 보고하며, 한국산 버들치속 어류는 총 5종이 한반도 이남지역에 분포하는 것으로 확인되었다.

  • A new three-dimensional transition solid elements was presented for the automated three-dimensional adaptive h-refinement where the steep stress gradient exists. To be consistent with 8-node solid element with nonconforming modes in accuracy, these transition elements were improved through the addition of the associated nonconforming modes. Numerical examples show that the performance of the element and the applicability to 3D adaptations are satisfactory.

  • Water quality was monitored from a watershed with small-scale livestock production farms. To evaluate pollution potential, land use, population, the size of livestock production of each farm, and livestock management were surveyed. Climate and stream flow data were gathered. Water samples were taken periodically for base conditions and some storm events. Pollutant loading was estimated by flow volume and concentrations of constituents.

  • This study was to evaluate the effect of leaf temperature on daily evapotranspiration of crop. A transpiring crop will be cooled by the vaporization of water to a temperature below that of the surrounding air. Leaf temperature was measured a infrared thermometer. Crop evapotranspiration was measured by the method of lysimeter. A statistical model for estimating evapotranspiration was developed and tested. It was showed that the model was applicable.

  • Salt accumulation is one of themajor problems in soils under protected cultivation . Since protected cultivation does not have rainfall or excessive irrigation, salt accumulaiton inthe soils is inevitable. In this study, characteristics of salt accumulation in soil column were ivestigated, and a salt-extracting method was tested to see its effectiveness. The results showed that the concentration of salt in top soil layers increased and electrical conductivity as thesalt concentration decreased especially in the top soil layer .When extraction medium was applied.

  • This paper presents an experimental study of a solar drying system designed and installed by KIER. Experiments have been performed using the KIER system for the drying of marine products, such as squid. Presented in detail are the experimental observations of collector air temperature, solar intensity, absorber plate temperature, drying chamber temperature, humidity and other measures of drying chamber performance with variation of air mass flow rate. As a result, average temperature attained in the drying chamber during autumn weather has been adequated for drying of squids.
