지난 수년 간 국내 광학산업은 눈부신 발전을 했다. 디지털카메라, 핸드폰카메라, 정보저장기기, 복사기와 같은 전자제품 시장의 성장, 평판디스플레이의 도약, LED 조명의 출현, 매 순간이 숨 가쁜 변화와 팽창의 연속이었다. 작년에 시작된 미국발 금융위기가 전 세계 신용경색, 실물경제 침체로 이어지면서 국내 광학산업에 먹구름이 드리워지고 위기감이 고조되고 있다. 본 원고는 해외 광학회사, 연구기관들과 협력하면서 고찰한 내용에 필자의 의견을 덧붙인 것이다. 이제는 국내회사들이 지속적으로 성장하기 위해서 세계 시장을 대상으로 '그레이트 게임'을 할 시기이다.

침체된 부동산 시장에 미국발 금융 위기가 찬물을 끼얹었다. 경기 악화로 미분양 아파트들이 대거 급증한 가운데, 금융권의 대출 상환 압박에 시달리면서 건설사들의 유동성 위기가 심각한 수준에 이르고 있다. 이에 대해 정부가 대주단 가입 등 건설 업계 회복을 위해 힘쓰고 있지만, 좀더 적극적인 개입이 필요하다는 목소리가 높아지고 있다.

이 땅에 농약산업이 발 디딘지 반세기가 흘렀고 우리 한국인에 의해 본격 운영된지도 40여년이 가까워 온다. 짧은 역사를 가지고 있지만 그간 어려운 여건 속에서도 괄목할 만한 성장을 거둔 우리 농약산업의 발자취를 더듬어 보는 것도 바람직스러운 일이 아닐 수 없다. 자료가 불충분하고 미비한 점에 대해서는 양해를 구하며 4회에 걸쳐 연재할 계획이오니 많은 참고 있기를 기대합니다.

Three Korean soybean varieties, Dawon, Taekwang, and Myeongiju-namul were investigated for changes in isoflavone and oligosaccharides contents, and dry weight during germination. Soybeans were soaked for 10 hr in water, followed by 8 days germination at $20^{\circ}C$ under dark condition, Highest isoflavone content measured was Myeongju-namul (1.228 mg/g), followed by Taekwang (0.671 mg/g) and Dawon (0.661 mg/g). Total isoflavone content generally increased during initial germination and decreased thereafter. Maximal increase in isoflavone was 20-50%, particularly in aglycone type such as daidzein and genistein. Raffinose and stachyose contents decreased rapidly during germination, while that of sucrose showed relatively slow decrease. Dry weights of soybeans steadly decreased.

This study aimed to enhance rutin contents by controlling germination condition for manufacturing buckwheat sprouts. Two kinds of buckwheat, a common buckwheat (Fagopyrum esculentum Moench) and a tartary buckwheat (Fagopyrum tataricum Gaertner) were used. By comparing the rutin content of two buckwheats, tartary buckwheat was 487 ppm, about 36 times higher than common buckwheat. Both common buckwheat and tartary buckwheat which germinated and grew under the light had higher rutin content relatively. In case of tartary buckwheat, rutin content of over 10 cm sprout was 4,579 ppm (without the light), and 5,160 ppm (with the light). Furthermore, tartary buckwheat was germinated and grew under different light strengths from 2,000 to 22,000 Lux. The rutin contents of tartary buckwheat sprout that was grown under the 22,000 Lux light was the highest. The rutin content was increased dramatically at 14,000 Lux of light. From 14,000 to 22,000 Lux, there was a little change on rutin content. Therefore, the condition of 14,000 Lux light was determined optimal for manufacturing tartary buckwheat sprouts. Also, rutin contents of extracts treated with 60, 70, 80 and $90^{\circ}C$ during different time had no significant difference. Therefore, rutin of tartary buckwheat sprout extract had thermostability up to $90^{\circ}C$.

It is considered that the application of advanced composite materials to the prostheses for the disables is important to improve their bio-mechanical performance. Particularly, energy storing foot prosthesis is mostly important to restore gait ability of the disables with low-extremity amputation since it could provide propulsion at terminal stance enhancing the disables ability to walk long distance even run and jump. Therefore, the energy storing spring of Prosthetic foot keel under cyclic bending moment use mainly of high strength glass fiber reinforced plastic. The main objective of this study was to evaluate the stacking sequence effect using the delamination growth rate(dA$_{D}$/dN) of energy storing spring in glass fiber reinforced plastic under cyclic bending moment. The test results indicated that the shape of delamination zone depends on stacking sequence in GFRP laminates. Delamination area(A$_{D}$) turns out that variable types with the contour increased non-linearly toward the damage zones.nes.

식물병원균 Botrytis cinerea와 Fusarium oxysporum에 대한 생물학적 방제의 기초자료를 얻기 위하여 살충성 진균 Beauveria bassiana의 식물병원균에 대한 균사성장저해, 포자발아 억제, 균사와 포자의 형태변화 등의 효과를 살펴보았다. 평판배지 상에서 두 식물병원균의 균사생장이 저해되었으며, 저해효과는 배지종류에 따라 달랐는데 B. cinerea의 경우 PDA배지에서 가장 크게 저해되었으며 F. oxysporum의 경우에는 TSA배지에서 가장 크게 저해되었다. B. bassiana는 $25^{\circ}C$에서 6일간 배양했을 때 F. oxysporum에 대한 항균력이 가장 높았으며 동시에 최대의 균체량을 생산하였다. 또한 B. bassiana의 배양여액을 식물병원균에 30% 농도로 첨가하여 배양했을 때 식물병원균의 포자 발아율은 B. cinerea, F. oxysporum에서 각각 30%(control: 88.2%), 10.0%(control: 78.6%)로 낮아졌으며 발아 개시 시간도 4~8시간 지연되었다. 현미경을 통한 미세구조관찰에서는 10%의 B. bassiana배양여액을 첨가했을 때 F. oxysporum의 포자 크기가 1/2~1/3으로 줄어들었으며 균사와 격막의 형태도 비정상적으로 변하여 균사외막과 격막-격막 사이의 구분이 불명확해졌다.

Organic matter in dredged soil has a lot of engineering problem in ground including a large settlement, crack propagation, low bearing capacity and low friction angle. From an agricultural point of view, however, organic matter contributes greatly soil quality and plant health. This paper investigated the relationship between engineering and germination characteristics of stabilized mixture consisting of different ratios of organic content (0 %, 10 %, 20 %, 30 %) for recycling dredged soil including organic matter. Several series of laboratory tests such as flow test, unconfined compressive test and consolidation test were performed to find out engineering characteristics. pH, percent of germination and growth of plants were also measured to investigate the germination characteristics. The experimental results indicated that, as organic content increased, unconfined compressive stress decreased and compression and swelling indices increased. However, percent of germination and plant growth increases as organic content increases.

This study was carried out to examine the possibility of using brown rice or paddy as raw materials for sikhe. Brown rice and paddy were soaked in water at $15^{\circ}C$ for 2 days and then germinated at $15,\;20,\;25,\;30^{\circ}C$ for upto 10 days. The higher the germination temperature, the higher the germination speed, the increase of ${\alpha}-amylase$ activity, and the increase of extract amount and its sugar content. The viscosity of extract rapidly decreased first and then slightly increased during germination. The activities of ${\alpha}-amylase$ of germinated brown rice and paddy were much smaller than those of germinated barley; however, the extract amount and its sugar content of germinated brown rice and paddy were similar to those of germinated barley. The germinated brown rice can be used for sikhe not as a saccharifying agent but as a substitute for white rice.
