  • 본 연구에서는 대규모 항만시설물을 계획함에 따라 발생될 수 있는 인근 소규모 어항의 안정성에 대하여 일예를 들어 검토하였다. 제주해군기지 건설로 인해 인근어항(강정항)의 기축조분 84m를 제외한 잔량분 126m에 대한 평면수정이 불가피할 것으로 판단됨에 따라 수치모형실험(SWAN)을 통해 강정항의 현 상태 및 기지건설 후의 항내파고 분포에 대하여 검토하였다. 또한 남방파제 잔량분이 미 시행됨에 따라 발생할 수 있는 항내정온도를 확보하기 위하여 대안을 연구한 결과 제주해군기지 서방파제 시점부에 파제제 50.0m를 설치함으로써 보다 효율적이고 경제적으로 인근어항(강정항)의 항내정온도를 크게 개선시킬 수 있을 것으로 판단된다.

  • Environmental and safety problems are one of the most important factors in designing coastal wave control structures and maintaining facilities in coastal zone. This study suggests the multi-cylinder piles as a profitable structure for preserving coastal zone as well as controlling the wave effectively. The hydraulic model experiment was performed to investigate the effect of erosion control of the structure. The experimental study was carried out to research the effect of erosion control in the coastal zone for existing a concrete wave breaker and the structure with multi-cylinder piles placing at the same location. As a result multi-cylinder piles reduced erosion at each sides of structure and occured sedimetation at front of structure.

  • In order to effectively control waves in a coastal zone, Multi-Cylinder Piles have been suggested as economic structures. A numerical analysis was conducted using the Delft-3D: WAVE module based on SWAN, which considered wave shoaling and refraction. Moreover, irregular waves were used to investigate the hydrodynamic characteristics of the wave interaction with the structure. In this paper, a numerical analysis was carried out to research the effect of wave control through a wave height analysis concerning an existing, concrete wave breaker and multi-cylinder piles placed at the same location. As a result, the effect of the wave control is shown using the wave breaker, multi-cylinder piles, and existing data.

  • In this study, expanded poly(tetrafluoro ethylene) (ePTFE) graft was modified to be used as a hemodialysis vascular access. Biodegradable poly(D,L-lactide-$co$-glycolide) (PLGA) was coated onto the inner surface of ePTFE graft with paclitaxel, which is often used as an anti-cancer agent and for reducing neointimal hyperplasia. Surface characterization before and after PLGA coating was carried out by SEM and ATR-FTIR. Porous sturcture of ePTFE was maintained after coating of PLGA solution. The amounts of coated PLGA and paclitaxel determined by ATR-FTIR and HPLC were 1.96 and 0.263 mg/$cm^2$, respectively. Young's modulus was decreased and tensile strength was increased by PLGA coating. Released paclitaxel as a function of incubation time was monitored by HPLC. Approximately 35% of coated paclitaxel was released steadily for 4 weeks with the biodegradation of PLGA. From these results, it is expected that the effect of paclitaxel on reducing neointimal hyperplasia and stenosis is maintained for a long time.

  • Field application of the entomopathogenic nematode, Steinernema carpncapsae, is limited by its susceptibility to UV irradiation and desiccation especially at leaf spray control. This study was conducted to develop the control technique using alginate biocapsulation of the nematodes against the beet armyworm, Spodoprera exigua and the tobacco cutworm, Sp. litura that are normally infesting hosts above ground level. The alginate capsules including infective juveniles gave significant feeding toxicities to the larvae of the two lepidopteran species. The lethality followed a typical sigmoid dose-mortality pattern with increase of the nematode densities embedded in the capsules. Moisture content in the capsule was critical to the survival of the infective juveniles. More than 80% nematodes could survive above 10% moisture content remained in the capsule. Remaining moisture content within the capsule was dependent on relative humidity, ambient temperature, and capsule size, but not on citric acid reaction time during capsule formation. More than 80% of infective juveniles in the alginate capsules could survive in distilled water at 15$^{\circ}C$ for 60 days. When these nematode capsules containing welsh onion extract as another phagostimulant were applied on the 3rd instar larvae of Sp. exigua infesting peanut plants, they resulted in about 90% control efficacy. These results indicate that the alginate capsulation can be used for leaf-spray agent of the entomopathogenic nematodes as well as for improved storage purpose.

  • Objective : This study was aimed at investigating the therapeutic effects of acupuncture on gastrointestinal side effect of Levodopa on idiopathic Pakinson's disease patients. Methods : The subjects of this study were 42 patients with idiopathic Parkinson's disease. We divided them into two groups; acupuncture treatment group, no treatment group. We treated the former group with acupuncture therapy focusing on gastrointestinal side effect of Levodopa while administering Levodopa as well. And the latter group was also dosed up with Levodopa without acupuncture therapy. To see the effect of acupuncture treatment clearly, we used gastrointestinal syndrome rating scale (GSRS) and visual analog scale (VAS) and compared the GSRS grade and VAS score of two groups statistically, after 1, 2, 3, 4 weeks since they have been under the treatment. Results : This study suggests that the group who has been treated with acupuncture on gastrointestinal side effect of Levodopa on idiopathic pakinson's disease patients showed higher GSRS grade and VAS score than the one that has not. But, We could't find statistical significance between the two groups on improvement of GSRS grade and VAS score. Conclusions : These results proved that acupucture theraphy might be available for re lieving symptoms related with gastrointestinal side effect of Levodopa than the one that has not. But further studies are necessary.

  • Four different plant growth retardants (PGRs), paclobutrazol, flurprimidol, daminozide, and chlormequat, were applied to potted Saxifraga rosacea 'Kumoma' and 'Kumoma-Gusa' plants for control of the growth and flowering. Paclobutrazol (10, 20, 40, $80mg{\cdot}L^{-1}$), flurprimidol (5, 10, 20, $40mg{\cdot}L^{-1}$), daminozide (500, 1000, 2000, $4000mg{\cdot}L^{-1}$), and chlormequat (50, 100, 200, $400mg{\cdot}L^{-1}$) were applied to the plants by a foliar spray or drenching. In 'Kumoma', application of $40mg{\cdot}L^{-1}$ paclobutrazol by a foliar spray or drenching reduced plant height by 12.5 and 12.6 cm, and flower length by 3.4 and 3.3 cm, respectively. On the other hand, in 'Kumoma-Gusa', drenching of paclobutrazol reduced plant height by 10.7 to 12.6 cm and flower length by 2.0 to 3.9 cm with increasing concentration, but the number of florets almost fell to 20 as compared to 40.5 in the control. 'Kumoma-Gusa' plants drenched with $80mg{\cdot}L^{-1}$ paclobutrazol and sprayed with $40mg{\cdot}L^{-1}$ flurprimidol had the shortest heights of 10.7 and 9.9 cm, and floral length of 2.0 and 1.5 cm, respectively. A flurprimidol drenching at $40mg{\cdot}L^{-1}$ delayed the harvest by 3-13 days as compared to the control and the smallest number of florets, 15.6, was observed in this treatment. In both cultivars, chlormequat and daminozide did not effectively influence the growth and flowering. However, number of florets increased to more than 41 at all concentrations and up to 63, the greatest floret number, with chlormequat drench in 'Kumoma-Gusa'. These results demonstrated that over $40mg{\cdot}L^{-1}$ of paclobutrazol or 5 to $20mg{\cdot}L^{-1}$ of flurprimidol could be used as PGRs to control the growth of floral length and flowering for improving potted plant quality in S. rosacea 'Kumoma' and 'Kumoma-Gusa'.
