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.

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.

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.

After the IMF financial crisis, a lot of risks in construction industry have been increased gradually with the expansion of construction industry widely, higher stories of building, and the expansion of the underground space and excavation work. These risks are bringing out constriction accidents such as the death, the injury of worker and so on, not so much as it would be effected the corporation's image. In spite of these situations, many constriction industries still maintain the wrong methods and riot try to decrease construction accidents. Decently, we should focus on the fact that larger construction industries have been endeavoring to decrease the accidents in construction site and the safety management system of the larger constriction also is being good, on the other hand, the condition of the work in the case of smaller construction industries is very poor, construction company have a particular safety management system but it has a difference according to the construction magnitude, construction companies have a particular safety management system but it has a difference depending on the construction magnitude. Thus, we need to study the smaller construction safety management to decrease the construction accident according to the construction magnitude. Therefore, this study will suggest the developed way of construction safety management by the comparison and analysis from the difference between the higher and the smaller construction industries.

배경 : 헤르페스바이러스과에는 단순포진 바이러스(HERPES SIMPLEX VIRUS, HSV), 수두대상포진 바이러스 (VARICELLA-ZOSTER VIRUS, VZV), 엡스타인-바 바이러스 (EPSTEIN-BARR VIRUS, EBV), 그리고 거대세포 바이러스 (CYTOMEGALOVIRUS, CMV) 등이 있다. 헤르페스바이러스 감염은 혈액암환자에서 조혈모세포 이식 환자에서 전파 (dissemination), 이차감염, 세균 중복 감염의 심각한 합병증을 일으킬 수 있다. 하지만 항암약물치료를 받는 림파종 환자에서 항 바이러스 약제의 사용 용량과 기간에 대한 concensus는 없다. 헤르페스바이러스 감염에 대한 발생율과 위험인자를 후향성으로 분석하였다. 방법 : 고신대학교 복음 병원에서 1995년 6월부터 2009 년 2월 사이에 새롭게 진단되어 조혈모세포 이식을 받은 전체 58명의 환자들이 후향적으로 현 연구에 등록했다. 헤르페스 바이러스 감염은 임상적 진단, 혈청학적 검사 또는 병리학적 진단에 기초하여 확진한다. 환자들의 특성은 다음과 같다: 평균 연령은 44세 (범위 19-62세)였고 남녀비는 30:28이었다. 등록된 질환은 백혈병 (n=9, 15.5%), 림프종 (n=30, 51.7%), 다발성 골수종 (n=12, 20.7%), 재생불량성 빈혈 (n=6, 10.3%) 그리고 골수이형성증후군 (n=1, 1.7%)이 포함되었다. 결과는 chi-squre test나 independent samples T test를 사용하여 분석되었다. Multivariate analysises에 대해 logistic regression test를 사용하였다. 결과 : 15명의 환자들 (25.9%)에서 조혈모세포 이식후 헤르페스 바이러스 감염이 발생하였다. 조혈모세포 이식 5년간 누적 발생율은 53.9%였다. Univariate analyses에서 헤르페스 바이러스 감염에 대한 유의한 위험 인자는 없었다. 하지만 조혈모세포 이식후 생존 기간(40.18 ± 30.14 months vs 20.06 ± 26.67 months, p=0.018)은 헤르페스 바이러스 감염의 낮은 발병율과 유의한 관련성이 있었다. 이식 편대 숙주질환 (GVHD)의 존재 (37.5% in developed GVHD vs 0% in no GVHD, p=0.200), 동종조혈 모세포 이식에서 면역억제요법의 기간 (15.98 ± 14.02 months vs 6.78 ± 3.67 months, p = 0.374)은 헤르페스 바이러스 감염에 대한 위험인자가 아니었다. 결론 : 조혈모세포 이식 후 생존 기간은 어사이클로비어 예방을 받은 혈액암 환자에서 헤르페스 바이러스 감염의 낮은 발병율과 연관성이 있는 것으로 보인다. 저용량의 어사이클로비어 예방은 헤르페스 바이러스 감염의 고위험군인 조혈모세포 이식을 받은 혈액암 환자에 필요하리라 생각된다. Background : Herpesviridae family includes herpes simplex virus, varicella zoster virus, Epstein-Barr virus, and cytomegalovirus, etc. Herpesviridae viral infection (HVI) can lead to serious complications including dissemination, secondary infection, bacterial superinfection in patients with hematologic malignancy following hematopoietic stem cell transplantation (HSCT). But there was no consensus on the dose and duration of antiviral agents prophylaxis in patients undergoing chemotherapy. We retrospectively analyzed the incidence and the risk factors for HVI. Method : A total of 58 patients who newly diagnosed and received HSCT with prophylaxis of acyclovir at the Kosin University Gospel Hospital, Busan, Korea between June 1995 and February 2009 were enrolled retrospectively in the current study. HVI was confirmed based on clinical diagnosis, serologic test or pathologic diagnosis. The characteristics of the patients were as follows: the median age was 44 years (range 19-62 years) with a female-to-male ratio of 30:28. The enrolled diseases included leukemia (n=9, 15.5%), lymphoma (n=30, 51.7%), multiple myeloma (n=12, 20.7%), aplastic anemia (n=6, 10.3%) and myelodysplastic syndrome (n=1, 1.7%). The results were analyzed using a chi-square test and independent samples T test. For the multivariate analysis, we used logistic regression test. Results : Fifteen patients (25.9%) developed HVI after HSCT. The cumulative incidence of HVI was 53.8% at 5 years after HSCT. In univariate analysis, there was no significant risk factor for HVI. The presence of graft-versus-host disease (GVHD) (37.5% in developed GVHD vs. 0% in no GVHD, p=0.200), duration of immunosuppressive therapy (IST) in allo-SCT (15.98 ± 14.02 months vs. 6.78 ± 3.67 months, p = 0.374) were not risk factors for HVI. Conclusion : The incidence of HVI was similar to that in historical other studies. There was no risk factor associated with development of HVI. Most of the HVI occurred within the first 24 months after transplantation. So long term use of antiviral prophylaxis may be needed to prevention of HVI after HSCT.

The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.
