In order to determine whether vegetation would be one of the factors for the selection of otter home range, vegetation structure and other potential factors were studied in Hwacheon, Korea. Thirteen sites, otter’s activity found and not found, were investigated in North Han River and connected tributary streams of Hwacheon-gun. Three types of vegetation were classified by cluster analysis, which is short grass, tall grass and shrub type. Vegetation zone of each channel is composed of either one type, or mosaic of tall grass and shrub type. Short grass type is common in Lake Paro and upper North Han-river where water level is highly variable throughout a year. Therefore, annual species such as Persicaria nodosa, Fimbristylis dichotomam and Chenopodium ficifolium are the most dominant. Shrub type is common at the downstream sites of Jichon stream and along mainstream of North Han River down Lake Paro. A shrub species, Salix koreensis, is the most common. Tall grass type is dominant occupying the most vegetation zone of the tributary channels. Phragmites japonica is absolutely dominant. Due to its dense cover, a few plant species are co-existed. Otter activity was found in all three vegetation types and no marked activity was found at some sites of tall grass type. There is no difference in species composition and physiognomy between tall grass sites with and without otter activity, while it shows significant difference in fish availability between two groups. Overall we found that home range of otters in the region is along the mainstream and downstream of tributary streams with high fish availability in all vegetation types and in various human activity levels.

This study was undertaken to observe the morphological changes of young adult worms(45th day after infection) of Paragonimus westermani obtained from experimentally infected dogs after treatment with praziquantel. For this study 8 dogs were artificially infected with metacercariae isolated from crayfish, Cambaroides similes. After 45th and 90th day of infection, three dogs were each given praziquantel 3×25 mg/kg×1day respectively, and autopsied at 24 hours after the last medication. With the young adult worms from the cysts in the lungs of treated dogs, the fine structural changes were observed by means of scanning and transmission electron-microscope. The findings were compared with those of adult worms in treated and untreated control host. The results are as follows: 1. The majority of the young adult worms obtained from the treated dogs showed a large balloon-shape structure on the tegumental surface between oral and ventral suckers. This structural change has never been reported in the adult worms obtained from the treated hosts. 2. The scanning electron-microscopy revealed formations of bleb-like structures on sensory papillae near the oral and ventral suckers. 3. The transmission electron-microscopy showed that the axons of the nerve endings in the sensory papillae around two suckers were degenerated and formed large vesicles which upon rupturing on the tegumental surface have formed bleb-like structures. 4. The numerous mitochondriae in the tegumental syncytium of the worms in treated hosts appeared to be degenerated and formed small vacuoles, and a different size of vacuoles interspersed in the distal part of the tegumental syncytium. These vacuoles were fused to each other and led to the disruption of the apical region of tegumental syncytium along the basement layer, which was finally detached from the circular muscles of the worm. 5. Many host cells (granulocytes) invaded and destroyed the degenerated tegument by the occurrence of blebs or the exposed muscular layer of the worm after exfoliation of the tegument.

Sealapex was comparied with a zinc oxide euaenol sealer over a 24-wk interval to examine solubility in an in vitro situation. After obturation with gutta percha and the appropriate sealer, speciemens were immediately immersed in a saline solution to challenge the solubility oh the sealers. The solutions were changed weekly to allow for a continued dissolution of the sealers. Aget immersed in methylene blue solution for 3 days, the speiemens were made transpatent by a clearing process. Microscopic examination was used to determine the lenear penetration of dye for each speciemen. Result revealed that sealapex had no greater dissolution than ZOE. Key words : Z.O.E., Sealapex, Solubility, Clearing process, Dissolution
위암환자에서 BrdU에 의하여 유도되는 Fragile sites의 발현

The expression frequency of BrdU-induced fragile sites was examined in stomach cancer patients to determine whether this parameter could be used as a marker of genetic susceptibility in at-risk individuals. G banding performed to detect fragile sites. No difference was found in expression frequency between the stomach cancer patients and a group of normal individuals(p=0.7). This indicates that the expression frequency of BrdU-induced fragile sites is not a suitable marker for assessing genetic susceptibility in stomach cancer patient.

Objectives : High serum cholesterol is one of the major risk factors of coronary artery disease. We investigated the lipid-towering property and the side effects of sesamin, an unsaturated fatty add extracted from sesame oil, for the primary prevention of coronary artery disease. Methods : The 37 patients (20 mates and 17 females) with hyperlipidemia, ages ranging from 22 years to 70 years old (48±12), who did not have atherosderotic diseases except essential hypertension were given three capsules of sesamin once daily for 6 weeks. The lipid profile of the patients were examined before and after sesamin treatment, and the patients were grouped according to the presence or abscence of hypertension, smoking habit and obesity. Result : Compared with pretreatment, the total cholesterol level of sesamin treated group decreased significantly (254.2±29.6 versus 241.6 34.0 ㎎/dl, p< 0.05). The level of LDL-cholesterol (162.6±24.3 versus 156.6±32.8 ㎎/dl)HDL- cholesterol (47.5±10.0 versus 47.0±8.7 ㎎/dl) and triglyceride (196.5±95.4 versus 179.3±96.7 ㎎/dl) and the ratio of LDL/HDL- cholesterol (3.6±0.9 versus 3.4±0.9) were not significantly different. The effect of cholesterol lowering property of sesamin was predominant in hypertensive, non- smoking and obese group (P< 0.05 vs pretreatment). The laboratory tests including complete blood cell counts, serum transaminases, total protein, albumin, blood urea nitrogen, creatinine and blood glucose did not change significantly. Conclusion : The lipid lowering effect of sesamin was statistically significant on the total cholesterol particularly with obese, non-smoking and hypertensive patients. There was no significant side effect during sesamin administration. Therefore, three capsules of sesamin as a single daily dose were effective in lowering total cholesterol and safe to administer in patients with hyperlipidemia.

As for the properties on both the aluminum and the CFRP which are used to make A17075/CERP multi-layered hybrid composites, CRALL(carbon reinforced aluminum laminate). For CRALL specimen, FEM analysis is compared with experimental results. It is shown that the rule of mixture is well agreed with experiment result in A/C 0001 layered 1 ply. However, differences are conceivable in A/C 0003 and A/C and A/C 0005 because of the effect of fiber volume fraction. In the A/C 0001 specimen case, the elastic modulus of the unnotched and circular notched CRALL specimen by FEM analysis are agreed with the experimental results, but that of A/C 0003 and A/C 0005 specimens had high CFRP volume fraction doesn't agree with experimental results.

The aim of this study is to prove that reconstruction policy has more effect on reconstruction projects than market by analysing the characteristics of reconstruced projects in Seoul from 1987 to 2002. The average of the expected life span of reconstructed housing is only 20.5 year. 296,637 housing unit was newly constructed where 163,485 housing unit was demolished in the case of Seoul. According to the change of reconstruction policy of housing, the number of reconstruction union and cases has been changed, The less regulated, the number of them increased while the more regulated, the number of them decreased.
