Biodegradable retinal fixation devices obtain mechnical fixation of the retina with desirable chorioretinal scarring and with the potential for local, sustained release of antimetabolites and steroids to inhibit proliferative vitreoretinopathy. We manufactured a biodegradable retinal tack with barb that was designed in order to prevent intrusion from implantation of retinal tacks. This study was carried to evaluate the efficacy for retinal fixation and the capability for sustained release of drugs with a newly designed biodegradable retinal tack Biodegradable retinal tacks were made of polymers of glycolic acids and were designed with barbs in a shape to prevent the disinsertion. Biodegradale retinal tacks are divided into 3 parts, a conical portion that is inserted into the sclera, a cylinder portion that remains in the vitreous, and a neck portion between the pin and the cylinder. The tapered conical end was manufactured to allow easy insertion through the retina and choroid into the sclera. A cylinder portion was manufactured with a tapered angle that fixes firmly into the orifice of 19 gauge spinal needle. A neck portion, 0.4 mm in diameter, was designed to prevent disinsertion from following implantation of retinal tack. The applicator was a 19 gauge spinal needle and its orifice was prepared to 15°angle to accept the tapered cylinder portion of the retinal tack. The retinal tacks, secured in the needles, were passed through the formed vitreous and inserted into the retina, choroid, and sclera and were released by pushing the internal needle, usually within 2-3mm of the medullary ray of the posterior rabbit retina A retinal tack was placed in each of 8 pigmented rabbit eyes. Slit-lamp biomicroscopy, indirect ophthalmoscopy and fundus photography were performed periodically from 1 day to 8 weeks after surgery. Eight eyes were enucleated and studied by light microscopy at 8 weeks. Biomicroscopic evaluation of the animals revealed edemas adjacent to the retinal surfaces immediately after insertion of the biodegradable retinal tacks in all the animals. These edemas disappeared after 1 week. The first noticeable change in the size of retinal tacks was shown after 2weeks. The size of the retinal tacks gradually got smaller, decreasing to about one-half at 4 weeks and about one-third at 8 weeks. All retinal tacks remained in inserted places without any movement for an 8 week period. On light microscopy, epiretinal proliferations were seen to extend into the vitreous cavity. Cellular capsules that lined the inner aspect of the scleral defect caused by tack insertion were found. However the adjacent retina had a normal cytologic appearance and architecture in all specimens. We manufactured a biodegradable retinal tack that is designed to prevent intrusion from implantation of retinal tacks. All biodegradable retinal tacks reduce in size with time, but no retinal tacks extruded from the inserted place. The newly designed biodegradable retinal tack can be used for retinal fixation and may be used as a vehicle for the introduction of pharmacologic agents to prevent the cellular events that promote proliferative vitreoretinopathy.

The rates of photodegradation, reactivities, and mechanisms of photooxidation for the aqueous solution containing with halogen derivatives of aliphatic hydrocarbons have been discussed with respect to the kinds of photocatalysts, concentration of photocatalytic suspensions, strength of radiant power , time of illumination, changes of pH of substrate solution, wavelength of radiation, and pressure of oxygen gas saturated in the solution. These aqueous solutions suspended with 0.5 gL^-1 TiO_2 powder have been photodecomposed in the range of 100 and 93.8% per 1 hour if it is illuminated with wavelength (λ≥ 300nm) produced from Xe-lamp(450W). The photocatalytic abilities have been increased in the order of Fe_2O_3 < CdS < CeO_2 < Y_O2_3 < TiO_2, and rates of photodegradation for the solution have maximum values in the condition of pH 6∼8 and 3 psi-O_2 gL^-1. These rates for the photooxidation per 1 hour were dependent on the size of molecular weight and chemical bonding for organic halogen compounds and the rates of photodegradation were increased in the order of C_2H_5Br < CH_2Br_2 < C_5H_11Cl C_2H_4Cl_2 < trans-C_2H_2Cl_2 < cis-C_2H_2Cl_2 The t_1/2 and t_99% for these solutions were 5∼21 and 40∼90 minutes, respectively, and these values were coincided with initial reaction kinetics(r_0). It was found that reaction of photodegradation has the pseudo first-order kinetics controlled by the amount of h^+_VB diffused from a surface of photocatalysts.

This study was conducted to investigate effects of cultivation area and planting time on bulb growth and enlargement of Lilium oriental hybrids in seed buld production. Planting time was divided into three periods such as May 15, 30, June 15 and Cultivation areas were alpine Daegwallyong and low land Kangnung area. The results were as follows: 1.The temperature of Daegwallyong from June to September was around 16-18℃ which was the optimum temperature for growth of Lilium oriental hybrids compared with above 20℃ of Kangnung area. 2.The bulb emergence rate in Kangnung area was 1-3 days faster than Daegwallyong. As the planting time was delayed, the bulb emergence rate was faster. 3.There was no significant difference in plant height between cultivation area and cultivars, but as the planting time was delayed, the plant height in Kangnung was much longer than Daegwallyong. 4.The chlorophyll content was high in the early planting time and that in Daegwallyong was higher than Kangnung. 5.The fresh and dry weight of leave was increased in Daegwallyong cultivation, compared with Kangnung. 6.The growth of underground parts such as numbers and length of basic roots and root system of stem roots in Daegwallyong was much better than Kangnung. 7.Virus infection rate in Daegwallyong was lower than Kangnung, but in the phytophthora blight and leaf blight vice versa. 8.The faster the planting time was, the higher the bulb weight was. And the bulb weight in Daegwallyong was 93% higher than Kangnung.

콘크리트 비파괴검사법인 충격공진법의 유용성과 적용 한계를 살펴보기 위하여 실험 및 이론적 연구를 수행하였다. 실험적 연구를 위하여, 다양한 개재물이 포함된 콘크리트 슬래브 공시체를 제작한 후 충격공진법을 적용하여 개재물의 존재 및 매설 위치를 찾아보았다. 공시체들 중 몇 경우에는 개재물의 위치를 정확하게 검출할 수 있었으나, 나머지의 경우에는 검출하지 못하였다. 후자의 경우에 있어서 그 실패 원인을 규명하고, 나아가 본 기법의 유용성을 결정하는 주요 인자들을 알아보기 위하여 유한요소 해석을 수행하였다. 본 연구는 충격공진법의 물리적 이해 증진과 향후 발전에 기여할 것이다. The usefulness and limitations of the impact-resonance method, which is a nondestructive evaluation (NDE) method for concrete, are studied by both experimental and theoretical methods. For the experimental study, several concrete slab specimens with various inclusions embedded were fabricated, and tested by the impact-resonance method. Some of the inclusions have been detected and accurately located, but some have not. The reasons for the failure in the latter cases have been investigated theoretically by using finite element analyses, from which the primary factors determining the success of the method have also been identified. This study will serve to enhance the understanding of the underlying physics and to improve the usefulness of the impact-resonance method as applied to concrete NDE.
