This study was carried to develop of anaerobic reactor to be able to maximize the organic removal efficiency using laboratory-scale anaerobic filter. The ceramic tube and pall ring media were tested for the applicability as packing media of anaerobic filter for the treatment of a dairy waste. This study was conducted to determine the anaerobic treatability of a dairy waste, and investigate the effects of ceramic tube and pall ring media. Anaerobic filters were packed with packing volume of 65% of total working volume. When treating a dairy waste, the organic removal efficiency of anaerobic filter packed with pall rings was a little higher than that of anaerobic filter packed with ceramic tubes. This was because the reactor packed with ceramic tube had clogging problems and substrate transfer limitations. It seemed that the reactor packed with ceramic tubes had uneven packing due to structural characteristics. The COD removals of ceramic tube and pall ring anaerobic filters were greater than about 91% and 94%, respectively, at organic loading rate lower than 5kgCOD/㎥/d. The COD removals of both reactors decreased to 80% with organic loading rate of 10kgCOD/㎥/d. Biomass capture and solid-liquid-gas separation efficiency seemed to vary with the type of media.

The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicit? may plaf a role ip. the degeneration of substantia nigra, which is the Hajorfocus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested. Therefore, the mechanism of neurodegenerafion and protective potential o( nicotine in PD were investigated in the experimental modeB of Pll using a neurotoxin, C57BL/6mice were administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg,j.p.). The degree of neurodegenerafion was determined by immunohistochemical stainiHB oftyrosine hydroxylase (TH). TH-positive cells on nigral sections were found 56.0 ±4, 57.9 ±6,52.315ce11s, 49.0±3cells, and 39,4±Scells at days 1, 2, 3, 4, 5, respectively (controls : 57.6±Scells). Hoechst and TUNEL staining showed no evidence of apoptosis. The exandnation on themice co-adrunistered with nicotine(0.2mgAg) and MPTP(30mgag) revealed a tendency ofnicotine protective effects. At days 4 and 5, the degree of TH-positive cells was decreased by20-30%, In corclusiffn, the role of apoptosis was not evidenced in this MPTP modeB of PB.The possible proteccon by nicotine should be elucidated with further studies.

Stabilization of organic sludges using earthworms was conducted in a laboratory to investigate the effect of feed rate on the vermistabilization, and feasibility of vermistabilization of various sludge was also carried out to further wider application of vermistabilization. Sludges used in this study were septic tank sludge, papermill sludge and brewery sludge. Sludge reduction, cast production, earthworm growth rate and cocoon production were monitored periodically to check degree of stabilization. Feed rate of septic tank sludge did not have a notable effect on the sludge reduction and cast production per unit weight or earthworm. There was also no difference in the earthworm growth rate per unit weight of the sludge removed among the different sludge feed rate. The amount of septic tank sludge, papermill sludge and brewery sludge per gram of earthworm per day were 0.06, 0.05, and 0.02g, respectively. The weight of increase of earthworm per unit weight of the sludge removed was 0.18g/g for the septic tank sludge, 0.21g/g for the papermill sludge, and only 0.06g/g for the brewery sludge. It was therefore concluded that brewery sludge was not suitable for vermistabilization mainly due to high organic content to be easily converted organic acid. The concentrations of several heavy metals, volatile solids, total organic carbon and total kjeldahl nitrogen in the cast were generally lower than those in the raw sludges.

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

A mixed potential integral equation(MPIE) for the induced current on a cylindrical perfect conductor with arbitrary thin cross-section is considered. The equation is applied to a strip for control of scattering field. The control is carried out by prediction of the current distribution for a prescribed pattern and than by extraction of resistance distribution on the strip using the relationship of each distribution which is established by physical optics. Examples of an efficient control is given with the appropriate optimization process for the nonuniform distribution functions.

Individual identification is a very important subject in the medicolegal field, and the main method for individual indentification is the demonstration of blood group substance in the blood, semen, saliva, sweat, urine and vaginal discharge etc. by serological technique with the immunized sera. Extracts of cerain plants contain the substance that agglutinates human red blood cells. This substance is called phytagglutinin, PHA. These PHAs that react only with specific types of red bloood cells, are called lectins. Recently lectins are used for classification or typing of blood or body fludis intstead of the immunized sera. Hemagglutinin acivites were tested for the extract obtained from the seeds of Celosia argentea L. The tests included agglutination titration, absorption test with selected human red blood cells, agglutination inhibition by human sera, savliva and urine. The results of these tests are summarized as follows ; 1. 1. Human red blood cells can be divided into two groups. One group was agglutinated by absorbed Celosia argentea L. extracts and the other was not. Therefore. The frequency of the former Cea(+) type was 96.6%(396) and the latter Cea(-) type was 3.4%(14) among the 410 human blood specimens tested. 2. Human whole blood can be divided into two groups. One group was agglutinated by absorbed Celosia argentea L. extracts and the other was not. The frequncy of former Wcea(+) type was 2.4% (10) and the latter Wcea(-) type was 97.6%(400) among the 410 human blood specimens tested. 3. Human sera can dividad into two groups by agglutination inhibiton status of Celosia argentea L. extracts to human red blood cells ; one group was inhibited and the other was not. The frequency of the former ICH was 97.1%(398) among the 410 human blood specimens tested, and the latter NCH was 2.9% (12). 4. Human saliva can be divided into two groups by the agglutination inhibiton status of C.argentea extracts to human red blood cells ; one group was inhibited and the other was not. The frequency of the former Sa-ICH was 29.0%(119) among the 410 saliva specimens tested, and the latter Sa-NCH was 71.0%(291). 5. Human urine can also be divided into two groups by the agglutination inhibition status of C.argentea extract to human red blood cells ; one group was inhibited and the other was not. The frequency of the former U-ICH was 19.0%(78) among the 410 urine specimes tested and the latter U-NCH was 81.0%(332). 6. It was demonstrated that there was no constant relationship between the blood types and the saliva types or the urine types which were divided by Celosia argentea L. extracts. 7. The intensity and frequency of agglutination inhibition status of Celosia argentea L. extracts were high in the order of the human sera, saliva and urine. Therefore, newly classified blood types, saliva types and urine types by agglutination or agglutination inhibition of Celosia argentea L. extracts may be applicable for the individual identification in the medicolegal field.

This article is an abstract of the prize-winner master plan for Wolmee Park in Incheon, Korea. The main theme of the park is the revival of the Korean traditional garden style. The park provides a place for citizens to understand and experience Korean traditional garden styles by emphasizing Koreas traditional images and feelings. In addition, cultural traditions are harmonized with modern characteristics of the park. The plan includes restoring Wolmee-haenggung(a temporary palace used to be in Wolmee Island) to hold its traditional meaning as garden and plate of the Wolmee Island. Main design ideas are summarized below. First, the conceptual meaning of jeong-won(庭園, garden) is represented separately: jeong(庭) and won(園). Jeong(庭) is a man-made place and reappeared as tangible objects with traditional forms. In contrast, won(園) with the concept of wonrim(園林), the universal principle of Korean traditional garden style, which focuses on the harmony between human and nature, is symbolically represented as wolmeegugok(月尾九曲, nine beautiful landscapes along the river). Second, to deliver the meanings of the place, various historical and cultural elements of Wolmee Island are metaphorically added to the traditional garden frameworks. And third, the plan basically orients to preserve the ecologically healthy natural environment of Mt. Wolmee. The park will contribute for Incheon citizens as well as people nearby by providing healthy environment and various recreational activities.
