Determination of Limiting Nutrient for Algal Growth by Algal Bioassay. Oh, Hee-Mock, Seog June Lee, Seong-Bin Kim, Mi- Kyung Park, Byung-Dae Yoon and Do-Han Kim (Environmental Microbiology Research Unit, Korea Research Institute of Bioscience and Biotechnology, Taejon 305-333, Korea and Water Resources Research Institute, Korea Water Resources Corporation, Taejon 305-390, Korea) Water quaiity and algal growth potential (AGP) using Microcystis aeruginosa were investigated from April to September 1997 in Daechung Reservoir. Secchi disk transparency was 1.1 m in August. Chlorophyll-a concentrations were higher than 10㎍/l at all samples. Total phosphorus concentration was in a range of 0.020∼0.027mg/l which is at the approximate value of 0.03 mg/l, the general critical level of eutrophication. These results indicate that Daechung Reservoir is in an eutrophic state except some temporary times and restricted sites. Phosphorus uptake rate of M. aeruginosa was higher in the water from the epilimnion than in the hypolimnion and also higher under light condition than under dark condition. Therefore, phosphorus uptake rate appears to depend on cellular phosphorous content and light condition, a meaning of endergonic process. Phosphorus was the most frequently limiting nutrient: phosphorus was limiting algal gowth in April and May, nitrogen, phosphorus and trace elements were the limiting factors for algae in August, and trace elements in September. If a fast growing alga, M, aeruginosa, is used as a test organism for assaying AGP, in vivo fluorescence instead of dry weight can be measured for algal biomass and incubation period can be reduced from traditional 14 days to 7 days.

In this study, ozone was adopted for the reduction and stabilization of waste sludge from the municipal sewage treatment plant. The waste sludge used in the experiments was primary sludge, excess sludge and a mixture of the two. The sludge cells and flocs were disrupted by ozonation resulting in the reduction of TSS and VSS concentrations. In the case of the primary sludge with a concentration of 20 gTS/L, the TSS and VSS concentrations were reduced 28%, 33% and the TCOD concentration was reduced 20% respectively. The consumption of ozone was 0.18 gO₃/gSS. In the case of the excess sludge with a concentration of 7.5 gTS/L, the TSS and VSS concentrations were reduced 37%, 41%, and the TCOD concentration was reduced 19% respectively. The consumption of ozone was 0.33 gO₃/gSS. In the case of the mixed sludge of 9.3 gTS/L, the TSS and VSS concentrations were reduced by 45%, 53%, and the TCOD was reduced 26% respectively. The desirable consumption of ozone was 0.27 gO₃/gSS. As ozonation proceeded, the level of SCOD increased due to the release of intracellular materials. However TCOD was reduced due to mineralization resulting from the transformation of organic materials to inorganic materials.

Lipomyelomeningocele is the most common malformation leading to spinal cord tethering. Nonetheless, these lesion continues to pose a challenge in patient management. The purpose of this study was to identify the clinical feature, candidate for surgical repair, and outcome of lipomyelomeningocele in young children and adults. We studied the magnetic resonance images and/or lumbar myelo-CT of lipomyelomeningocele performed between January 1987 and September 1995 at our institutions and reviewed the pertinent medical records and radiologic studies to determine clinical feature, surgical candidate, and outcomes of these patients. Of the 14 cases(11 female and 3 males) studied, the most common factor that caused these patients to seek help was the cosmetic effect of the mass on their back, followed by urinary incontinence, and weakness of lower extremities. The patients' age ranged from 2 months to 21 years(mean, 5.0 years). All the patients underwent immediate surgical management that consisted of removal of lipoma, untethering of the cord, and complete dural sac repair. Follow up for these patients ranged from 6 to 82 months(median, 54 mo). None of the patients that underwent surgical correction before the emergence of neurological deficit had ever developed neurological deficits at the end of the follow up. However a few of the patients, despite presented with neurological deficits or urinary incontinence at the time of surgery, improved significantly. In conclusion, early detection and prophylactic surgery is imperative to prevent permanent neurological deficits and urinary dysfunction.

The aim of the present study is to evaluate effects of Spheroid 9000NS applied to 10 elderly patients with Chronic Low Back Pain. The effects were measured and analyzed by means of MPQWL, VRS, VAS-I and VAS-U after 4, 8 and 12 weeks, respectively, during the 12-week application of the Spheroid 9000NS. From the findings of the measurement and analysis, following conclusion could be drawn: 1. Significant reductions in MPQWL were confirmed at each period of measurement since the use of Spheroid 9000NS(p<.001). 2. Significant reductions were also revealed in VRS at each period of the measurement(p<.001). 3. Significant reductions were also revealed in VAS-I at each period of the measurement(p<.001). 4. The same reductions were found as well in VAS-U 4, 8 and 12 weeks after the application of the Spheroid 9000NS(p<.001). In sum, it may be concluded from the outcomes that the use of Spheroid 9000NS may help reduce drastically Chronic Low Back Pain, mostly effective to remove them speedily and safely. Patients, rehabilitation therapists and health experts are, therefore, recommended to employ the products as safe and effective means to control pains. Continued researches and experiments should further be conducted to collect more data from the larger population of patients with particular diseases in clinical situation, though.

Painful stiffness of the shoulder is an ill-defined clinical entity that is difficult to assess and delicate to treat. The nomenclature used is broad and includes terms such as frozen shoulder, adhesive capsulitis, focal algodystrophy, stiff shoulder, contracted shoulder, and others. Apart from its idiopathic form, the disease can be initiated by trauma, infection, tumour, radiation, systemic and local metabolic disturbances. Pathoanatomically, the common denominator is an inflammatory vascular proliferation followed by thickening, scarring, and retraction of the joint capsule. The inflammatory process often starts at the rotator interval and may extend to the subacromial space. Clinical diagnosis is based on history and physical examination. Generally the onset of pain precedes the perception of a reduced range of motion by weeks or months. In early stages of the disease, the inflammatory type of pain dominates, i.e., the patient's main complaint ist pain at night. In the later stage, range of motion gradually decreases. Patients do not often complain about reduced motion, probably because of its slow onset. The purpose of this study is to find out the effectiveness of the massage applied to the patients with Frozen Shoulder by measuring, assessing and analyzing the changes in intensity and unpleasantness of pain and range of motion(ROM) before and after massage. Surveyed from Jan. 2001 to December 2002 were 104 patients suffering from Frozen Shoulder. In the therapeutic massage program, such methods as Effleurage, Petrissage and Deep transverse friction were selected as they are among traditional massage treatments frequently used for joints with pain and restricted ROM. Effleurage and Petrissage were applied for 20 minutes in total before and after Deep Transverse Friction. After massage program, the intensity and unpleasantness of pain were measured and analyzed by means of VAS(visual analogue scale)-I and VAS-U, while ROM was measured and analyzed by using Goniometer. The major findings from this study are as follows; 1. The surveyed patients range from 28 to 75 in age, with highest numbers of 44(42.31%) registered in the fifties and next ones of 24(23.08%) in the forties. Divided by sex, 59 are women and 45 are men totalling 104 with average age of 51.4. 2. There was significant decrease in the intensity of pain and unpleasantness of pain after massage(p<.05). 3. There appeared, however, significant increase in ROM after massage(p<.05). 4. From the analysis into chronological changes in ROM before and after massage with ANOVA, it became evident that the longer the period of treatment was, the higher the ROM increases drastically, while significant difference was shown in Abduction and in External and Internal Rotation(p<.05). Summed up, it can be generally concluded that massage is an effective treatment to rid the patients with Frozen Shoulder of pains safely and promptly. This study was conducted to determine more accurate impact of massage. From the above outcomes, it was revealed that massage has proven to reduce the pains, exercising huge influence to increase ROM. It is, therefore, suggested to continue and expand the study on the cure of Frozen Shoulder and to motivate patients, orthopedists, physiatrists, physiotherapists, and sports massagists etc. to consider massage as safest and most efficient pain remedy.
