The aim of this study was to evaluate the effect of 3 environment- friendly farming materials on the growth of pepper and tomato seedlings under low level of solar radiation. The pepper and tomato seedlings were separately grown on commercial substrate and non-fertilizer substrate under 30% shading condition, respectively. The microbe-, enzyme-, and amino acid-supplements were used for the foliar application to the seedlings. The application of enzyme- and amino acid-supplements significantly enhanced the growth of tomato and pepper seedlings grown on non-fertilizer substrate, while there was no significant effect on the seedlings grown on commercial substrate. The foliar application of enzyme- and amino acid-supplements reduced the days to flowering by 3 to 4 days and lowered the node order of fruit set in tomato plants grown on non-fertilizer substrate. The results showed that the enzyme- and amino acid-supplements could enhance the seedling growth and lower the node order of fruit set under limited nutritional conditions.

Cylindrical chamber silencers with an extended inlet and outlet are widely used to reduce the propagated noise in ducts in many application fields. In this study, an acoustic analysis is carried out for concentric extended pipes inserted into a simple expansion chambers An algebraic equation is derived by using the eigenfunction expansion and orthogonality principle. Using this analytical method, transmission losses are predicted for several configurations of the concentric extended systems.

A real time process control package was developed in an INTEL 80386 based PC and MS OS/2 environment using MS-C and MS-FORTRAN. RTACS(Real Time Advanced Control System), process control computer software for distributed or centralized architectures, is a package which meets functional requirements specified for typical continuous process applications like chemical processes. The package consists of 5 parts, which are DB(data base), OCF(Operator Console Functions), CL (Control logic Library), MSM(Multitasking and Scheduling, Manager) and UAI(User Applications Interface), based upon a table and function block architecture to improve the system performance.

본 연구에서는 도로 빗물받이의 차집효율을 분석하기 위하여 측구 부분을 대상으로 수리모형을 제작하여 실험을 실시하고, 실측된 결과를 FHWA의 범용프로그램인 Visual Urban 모형의 해석결과와 비교하여 이 모형의 국내 적용성을 분석하였다. 실험에는 국내 표준규격인 40x50cm의 쇠살대 유입구(grater inlet)를 사용하였으며, 측구의 유량은 도로의 차선 및 빗물받이의 간격을 고려하여 $4\~13{\ell}/sec$를 선택하였다. 도로의 종경사는 $2,\;4,\;6\%$를 선택하고, 측구의 횡경사는 $4,\;6,\;8\%$를 선택하여, 총 36회의 실험을 실시하였다. Visual Urban 모형을 적용하여 모의한 결과와 실측값을 비교한 결과 종$\cdot$횡경사가 작은 경우에는 오차의 범위가 $6\%$정도였으며 종경사 $4\%$, 횡경사 $8\%$이상이면 비교적 일치하였다.

춘천지역에서 포획한 한국 야생랫드(시궁쥐)에서 Capillaria hepatica에 자연감염된 예를 보고한다. Capillaria hepatica의 충란이 포획된 68마리의 랫드중 17마리에서 발견되었다. Capillaria에 감염된 랫드의 간장은 충란과 함께 림프구, 단핵구, 호산구의 침윤이 관찰되었고 심한 괴사소견을 보였다. 또한 섬유화, 출혈 hemosiderin의 침착이 뚜렷하게 관찰되었다. 최근 국내에서 자연에서 채집된 랫드의 Capillaria hepatica의 감염을 보고한 자료가 없는 것으로 미루어 Capillaria hepatica의 숙주감염을 파악하는 자료로 활용될 수 있을 것이다.

In this paper, we introduce the definition and concept of trusted reality (TR) technology, which is a new paradigm that is required as human communication methods change into "see-thru communication." The trends related to a TR-see-direct interface, TR-privacy, a TR-physical/cyber object/service connection, and TR-open platform technology as core technologies for realizing TR are also introduced. In addition, we present a new ICT stream that can be used to build a new ICT ecosystem for the post-smartphone era.
