인공위성영상을 이용하여 벡터 지도 생성은 지형에 따른 건물, 도로, 농지 등에 관한 벡터를 추출하는 작업이 필요하다. 이 작업의 정확도는 지도의 정확도와 상관관계가 있기 때문에 건물 추출의 정확성이 달라진다. 따라서 건물추출의 정확성을 향상시키기 위해 본 연구에서는 위성영상에서 건물 추출 알고리즘을 제안하였다. 이 알고리즘은 인공신경망을 이용하여 건물의 그림자를 추적하고 이를 중심으로 건물위치와 외형을 추정하는 알고리즘을 제안하고 실험하였으며, 양호한 결과를 얻었다.

Effect of BA concentrations and culture methods on in vitro plant multiplication from shoot-tip cultures of Wasabia japonica was studied. Shoot-tips with leaf primordia and apical meristem were cultured on MS basal medium for all the experiments. Liquid medium for 2 weeks followed by semi-solid medium for 4 weeks containing 1.0 mg/L BA was the best to number of shoots (22.8) and shoot length (3.5 cm). Shoots proliferated could be divided into ca. 5 to 11 of cultures for the multiplication of plantlets. Divided plantlets showed root formation (90%) well onto MS basal medium without growth regulators like IBA and NAA. After rooting, all the plantlets transferred into the pots containing composed soil (bio-media Co., peatmoss $8{\sim}10%$, coir dust $66{\sim}70%$, zeolite $13{\sim}17%$, vermiculite $3{\sim}7%$, perlite $2{\sim}4%$) and grown well into whole plants with multiple shoots.

Iliacus muscle tears are a rare injury seen after the high-energy trauma or as a result of low-energy injuries in patients with a bleeding diathesis as coagulopathy, receiving anticoagulation therapy and hemophiliac. Femoral nerve palsy due to compression from a hematoma by iliacus muscle rupture are rarely reported. Routine evaluation includes MRI to confirm and define the pathologic abnormality supplemented by EMG and nerve conduction studies to evaluate patterns and extent of femoral nerve injury. Hematologic evaluation for bleeding diathesis may preceded, if suspicion of coagulopathy is present. We report the case of a healthy 32-year-old male with iliacus rupture and concomitant femoral nerve palsy sustained by kicking motion during soccer game. After 6 months of observation with non-operative treatment regimen, satisfactory results were obtained, so we report it with a review of the literatures.

To develop a new propagation method of Korean ginseng (Panax ginseng C.A. Meyer) by cutting, stem cuttings with leaflets obtained from ginseng seedlings were planted in rooting media treated with three levels of NAA concentration. NAA solution of 1.0 ppm was the most effective for the rooting of ginseng stem cuttings as well as for root growth after initiation of the roots from cuttings. A mixture of sand and leaf compost as a rooting medium for ginseng stem cuttings showed the best results in rooting percentage of cuttings and root growth after rooting. An acril film cap covering was very effective to prevent water loss by transpiration from the leaflets of stem cuttings and for rooting and root growth after rooting. Cuttings of leaf petiole with 5 leaflets from 2 year old ginseng plants showed good rooting as well as root growth after rooting in a mixture of sand and leaf compost treated with 1.0 ppm NAA.

This study was conducted to determine the optimum rooting media composition for the production of high-quality rose cuttings. The percentage of rooting was highest in peatmoss (P) and coarse vermiculite (CV) mixture (1:2, v/v). In 'Little Mable' and 'Suplesse', the rate was above 95%, and 'Red Velvet', 'Noblesse', 'Rote Rose', and 'Sweetness' showed 100% rooting rate. 'Rote Rose' showed lowest rooting rate, but in the composition, the rate was 100%. In the composition, root growth was accelerated. Root number, root weight, and root diameter increased in P:CV (1:2) mixture. However, root length increased in peatmoss and perlite mixture (1:2). This results might be caused by the water holding capacity and porosity of the rooting media composition.

This study was conducted to investigate effect of activated charcoal on growth and yield of Scutelltaria baicalensis G. in different degree of activated charcoal consistency. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal 30%, and short in control. Also stem diameter was shown the thickest in activated charcoal 30%, and thin in control. Length of main root and thickness of main root were good in activated charcoal 30%. Quality and yield of Scutellaria baicalensis G. were the highest by activated charcoal 30%. Therefore, optimum consistency of activated charcoal was activated charcoal 30%.

The optimum culture conditions for tropane alkaloid production in hairy root cultures of Korea native Scopolia paviflora Nak. were investigated. Hairy root was induced from the rhizome of the mother plant on B5 medium containing 1.0 mg/L IBA. Among the culture media examined, 1/2 B5 medium was the best for tropane alkaloid production, whereas the growth of hairy root increased in SH medium. The best result on the growth of hairy root was obtained in 1.0 mg/L NAA, and tropane alkaloid production was obtained in plant growth regulator-free medium. Of the carbone sources tested, 3% sucrose promoted the growth of hairy root, whereas 5% sucrose increased tropane alkaloid production. Optimum inoculum densities for root growth and tropane alkaloid production were 0.5 g and 1 g, respectively. The addition of XAD resins (1 % w/v) to hairy root cultures led to increases in tropans alkaloid production, and the release of alkaloid into the medium and its adsorption by the resin accounted for about 50 to 80％ of total production. It is concluded that optimized culture conditions and the addition of XAD resins could be used in the development of a bioprocess for tropane alkaloid production in hairy root cultures of S. paviflora Nak.

This study was conducted to investigate the effect of activated charcoal on growth and yield of taro in different degree of activated charcoal concentration. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal of 10-20％, but shorter in control. Also stem diameter was shown the thickest in activated charcoal of 10-20%, but thinner in control. Length of main root and thickness of main root were good in activated charcoal of 10-20%. Quality and yield of Bupleurum fatcatum was the highest in activated charcoal of 10-20%. Therefore, optimum consistency of activated charcoal was 10-20%.
