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.

Recently, soft tissue expansion technique using tissue expanders has become a popular method for reconstruction of soft tissue defect because it provides high quality tissue with similar color, texture and hair bearing characteristics without significant donor site problems. During the period September, 1983 to December, 1988, we used tissue expanders to treat 36 patients with soft tissue defect, 3 scalp, 10 face, 6 neck, 4 trunk, 10 upper extremity, 3 lower extremity and evaluated the operative techniques, results and complications as follows. 1. We achieved favorable results in 31 cases(86.1%), especially in scalp, face and upper extremity, but poor results in lower extremity, especially below knee in location. 2. We experienced major complications in 2 cases(5.6%) such as implant exposure and minor complications in 7 cases(19.4%) such as hematoma, partial necrosis, infection, underlying bony depression etc. 3. Capsular excision is not desirable, but capsular release may permitted to acquire maximal length of the advancing flap. 4. In case of microtia, expanded tissue which was obtained from expanders is defficient for elevation of framework without skin graft. 5. Accurate and meticulous preoperative evaluation is the most important factor in achieving good and results.

From this research, the performances of a sludge reduction in the sewage sludge aerobic digestion was experimented by using a sludge pretreatment and membrane bioreactor. The submerged plate membrane was used as the solid-liquid separation membrane . After drawing small amounts of sludge in a bioreactor and then doing the alkaline treatment and ozone treatment, the sludge was sent to back to the reactor. The HRT in the reactor was set as 5 days and the operation in the reactor was carried out at the DO of 1㎎/L on average. After 100 days of operation in the reactor, it was shown that the reduction efficiency of total solids was more than 83%. Most of volatile solids were removed through mineralization, and the considerable portion of the nonvolatile solids was dissolved and then flowed out with the effluent. Only about 16.3% of total solids in the sludge was accmulated in the reactor even without the loss of volatile fraction. Also, by deriving nitrification and denitrification in one reactor simultaneously, more than 90% of nitrogen removal effect was realized and the experiment was run smoothly without fouling of membrane, even in the high concentration of MLSS. Based on this experiment. sludge can be reduced considerably at a low HRT by these two newly suggested approach.

This study was conducted to examine the changes in the seed physical characters and germinative properties of three tree species at three different storage times in order to determine the most suitable storage time and condition. Seed physical characters and germinative properties were examined from seeds of Fraxinus rhynchophylla, Zanthoxylum schinifolium and Staphylea bumalda that were stored at -18C for 1, 3 and 10 years, and the growth performance and physiological characters of their seedlings were analyzed. Seed physical characters and germinative properties showed significant differences between three storage times as well as three tree species. Seed moisture content of F. rhynchophylla and S. bumalda and seed fresh weight of Z. schinifolium decreased with increase of storage time. Storage time represented negative correlation with moisture content and fresh weight (r = -0.822, p < 0.01). Seed percent germination of Z. schinifolium and S. bumalda stored for 3 and 10 years decreased less than 15% and 10.7% respectively. Mean germination times for seed of F. rhynchophylla, Z. schinifolium and S. bumalda were delayed 11.9, 5.7 and 9.7 days after a storage time of 10 years, respectively. However the growth and viability of seedlings didn't show a special pattern for storage time and tree species.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

This study on the environmental-ecological functional value of reclaiming from wet land for a standard of refutation on development and preservation. Korean wet land gives us seafood, social and cultural service of human and livelihood to be self-supporting the foods, supports etc, but at the same time wet land has ecologically sensitive and irreversible features. So we need to have maintainable management strategies considered the safe minimum standards. But Korean wet land has been developed 30% since 1980, and other wet land remain undeveloped has been pressured to develop. Pre-studies have been careless about the negative functions about water quality of paddy. But by the results of this study, we can know that total economic values are negative effects. The negative effects of environment pollution are bigger than the affirmative. And we need to compare and analyze the economic value of wet land and reclaimed land in order to produce more exact cost-benefit analysis on the preservation and development. But when we consider economic value of the liquid-quality purification between wet land and reclaimed land, the value of wet land is greater than reclaimed land.
