EU시장통합에 의욕을 가진 미테랑 대통령은 경제기반의 강화, 금융.자본시장의 개혁에 적극적인 태도를 보였다. 1992년에는 14년 만에 약 57억 달러에 이르는 무역흑자를 기록하는 등 농산물과 군수품 및 첨단 분야의 수출이 호조를 보였다. 제2차 세계대전 후 비약적인 발전에 대응하여 농업도 큰 변화를 계속하고 있다. 농업의 비중은 다른 선진 공업국에 비해 큰 편으로, 오늘날에도 여전히 공업국인 동시에 농업국으로서의 위치를 지키고 있다. 지금은 기계화 중심의 대규모 농업이 이루어진다. 그 결과 농업경영의 통합이 촉진되어 농가수가 크게 줄어드는 경향으로, 농촌인구의 도시 유출이 현저하다. 프랑스에서 산출되는 농산물의 종류는 대단히 풍부하다. 국토의 25%가 목초지인 프랑스는 소와 말 사육을 비롯한 축산업도 활발하게 진행되고 있으며, 북경 오리생산업체인 Orvia가 프랑스에 있다.

Objective: This study was conducted to comprehensively analyze domestic and international literature on the oral sensorimotor intervention approaches and evaluation/non-instrumental assessment methods for children with cerebral palsy with feeding disorders. Methods: One hundred and seventy-six papers published from January 2009 to December 2018 were screened. Forty-seven papers were selected based on the abstract and title, and five papers were selected through a secondary search. Results: The PEDro scale of the selected papers was high with an average of 7 points, and the therapeutic intervention period was found to be between 2 and 6 months, providing therapeutic interventions once to 5 times a week, at least 15 minutes to 1 hour a day. The treatment approach was used with impairment-based intervention and adaptive-based intervention, and the assessment method was divided into clinical evaluation and non-instrumental assessments. Conclusion: Through this systematic review, we found that there are a variety of oral sensorimotor interventions for children with cerebral palsy with feeding disorders. This study provides support for planning oral sensorimotor intervention programs for occupational therapy in clinical practice for children with cerebral palsy.

Where an interchange is located just after a tunnel not only it is impossible to install the traffic signs in tunnel sections but also sufficient sight distance to identify the interchange can't be provided. The objective of this study is to suggest the safety based spacing between tunnel and interchange. For this study accident rate was used as an index representing characteristics for vehicle operation to suggest the appropriate spacing. Traffic volume and the number of accidents on freeway from 1992 to 1997 were analyzed. The relationship between accident rate and spacing represents negative logarithm function such that shorter spacing increases accident rate. An appropriate safety based spacing between tunnel and interchange for four lane freeway with the design speed of 100kph was found as 2.6km.

It was verified that the effect of the distance between current input point and output point on direct current potential drop(DCPD) in the material with two-dimensional surface notch. If the distance between potential drop measuring points was fixed at a certain distance, the potential drop was decreased with increasing the distance between current input and output points. Hence it is the effect way to increase sensitivity in DCPD that the current input and output points should be located near the potential measuring points. DCPD was a useful method for surface crack sizing because the potential drop was proportional to the length of notch. When the current input and output points are located near the potential measuring points, even small length crack can be measured by DCPD technique.

This study was conducted to investigate the effect of tall type mixtures(TM) and tall + short type mixtures(TSM) on nutritive utilization. DM intake, digestibility and utilization of nitrogen and energy of herbages from pastures by Korean native goats were determined. This experiment was conducted by total collection method in laboratory, 2000. The experimental herbage included two treatments: Tall type mixtures(orchardgrass, Potomac 40+tall fescue, Fawn 20+Festulolium braunii, Paulita 10+perennial ryegrass. Reveille 10+timothy, Climax 10+red clover, Kenblue 5+alfalfa, Vernal 5%), Tall+short type mixtures {orchardgrass, Potomac 40+tall fescue, Fawn 20+Kentucky bluegrass, New port(turf type) 10+redtop, Barricuda(turf type) 10+perennial ryegrass, Palmer III(turf type) 10+red fescue, Flyer II(turf type) 5+white clover, Regal 5%}. The voluntary dry matter(DM) intake of Korean native goats fed with herbages from tall+short type mixtures(TSM) was slightly higher than that of tall type mixtures(TM), but no difference was observed between TSM and TM(p > 0.05). The digestibility of DM, neutral detergent fiber, cellular contents and acid detergent fiber of herbage from TSM was slightly higher than that of TM, but no difference was detected between TSM and TM(p > 0.05). The utilization of nitrogen and energy by Korean native goats did not showed any difference in herbages from TSM and TM(p > 0.05). In conclusion, the herbage utilization by Korean native goats did not showed any significant difference. Thus, there is a possibility that turf grasses in mixtures can be used as a forage sources.

Three kinds of natural pesticides extracted from plants which are being sold in the Korean markets, were estimated effects on materials of art of museum. Tested samples were 1) silk fabrics : undyed, dyed(amur cork tree, gallut, gallut(alum post mordancy), gallut(copperas post mordancy), gardenia, turmeric, acorn, acorn(copperas post mordancy), gromwell, madder, madder(alum post mordancy), safflower, sappanwood, sappanwood(alum pre mordancy, post mordancy), indigo, indigo+amur cork tree, indigo+sappanwood) 2) cotton fabrics : undyed, dyed(amur cork tree, gallut, gallut(alum post mordancy), gardenia, acorn, acorn(copperas post mordancy), gromwell, madder, madder(alum post mordancy), safflower, sappanwood, sappanwood(alum pre mordancy, post mordancy), indigo, indigo+sappanwood) 3) undyed ramie fabric 4) Korean papers : undyed, dyed(sappanwood, indigo, gardenia, amur cork tree, safflower) 5) pigments : azurite, malachite, red lead, litharge, orpiment, hematite, iron oxide, cinnabar, vermilion, indigo, lake indigo, kaolin, lead white, oyster shell white 6) painted plates : azurite, malachite, red lead, litharge, orpiment, hematite, iron oxide, cinnabar, vermilion, indigo, lake indigo, kaolin, lead white, oyster shell white. Conditions of tests were that after samples were exposed to 10 times of promoted concentration for 9 months in relative humidity $55{\pm}1%$ and temperature $20{\pm}2^{\circ}C$, they were compared with standards. Items of estimation were color difference(${\Delta}E^*$) and tenacity. After exposure to pesticides, undyed silk cotton ramie fabrics and Korean papers were not nearly changed in their colors, but colors of most of dyed samples were clearly changed by pesticides except for partial samples(acorn- and madder-dyed fabrics etc, gardenia-dyed samples). Especially changes of colors of turmeric-dyed silk fabrics were most distinct. And colors of pigments and painted plates containing lead, copper, arsenic, mercury and vegetable pigments, were clearly changed. Tenacities of yams of undyed silk fabrics were not nearly changed and undyed cotton fabrics were a little reduced as compared with standards. But tenacities of yams of dyed silk and cotton fabrics were clearly reduced or increased as compared with standards. Especially, madder-dyed silk fabrics were increased 10% or more and indigo-dyed silk fabrics were reduced 10% or less in all pesticides. Also madder- and sappanwood(alum post mordancy)-dyed cotton fabrics were increased 10% or more in all pesticides.
