This study reports the effectiveness of traditional Korean medicine in treating tetraplegia and respiratory symptoms (including dyspnea) after traumatic cervical spinal cord injury surgery. The patient was treated with complex Korean medical treatment including electroacupuncture, pharmacopuncture, and herbal medicine. The manual muscle test (expanded Medical Research Council system) was used to measure the patient's muscle strength. The Korean version of the modified Barthel index and the functional independent measure were used to evaluate the patient's independence in performing daily activities. Following 2 hospitalizations and treatments, the patient's muscle strength improved > 4+ score for all joints, and the Korean version of the modified Barthel index and functional independent measure scores increased from 26 to 79 and 56 to 95, respectively. Symptoms of dyspnea, coughing, and sputum gradually improved and finally disappeared during hospitalization. This study suggests complex Korean medicine treatment may be effective in the rehabilitation of post-surgical cervical spinal cord injury patients.

본 논문은 정수장에서 사용하는 응집제의 종류와 주입량을 결정하기 위한 시스템 개발에 관한 내용이다 정수장은 여러 단위 처리장으로 구성되며, 탁도와 색도를 제거하기 위하여 혼화지에서 응집제를 주입하여 침전을 시킨다. 현재까지 응집제 결정을 위해 Jar-test를 이용하였는데, 이 방법은 사람의 주관적인 판단에 의존하므로 실험 오차가 발생할 수 있다. 특히정수장의 자동화를 위한 시스템 개발에서 가장 큰 걸림돌로 작용하고 있다. 본 논문은 이러한 문제점을 해결하기 위하여 데이터 마이닝 기법 등을 이용한 응집제 종류와 양을 결정하는 제어기를 개발하였다.

The objectives of this research are to investigate the proper coagulation conditions which are a type and doses of coagulants, mixing conditions (velocity gradients and mixing times), pH and so on through Jar-test, to evaluate the flux variations, permeate, backwashing according to characteristics of pretreatment of the wastewater by means of MF membranes for river maintenance water reuse. The effluent water from B-city K-sewage treatment plant are used for this research. Turbidity and suspended solids(SS) are 14.2 NTU and 10.4 mg/L respectively. This condition causes fouling for membrane process. The flux decline could be reduced when coagulation pretreatment was carried out. Optimal coagulations PAC which are commonly used in the sewage treatment plant was observed in this research. The results indicate that an optimal coagulation dose and pH are 80 ppm and pH of 7 respectively, but coagulation efficiency was lower at strong acid or strong base. Results showed that continuous and steady operations in membrane separation process by means of the effective removal of organic matter and turbidity with coagulation pretreatment of sewage secondary effluent were achieved.

The purpose of this study is to investigate the effect of various types of coagulant on dewaterability and settleability of sewage sludge for the application of dewatering process. Cationic organic coagulants and inorganic coagulants of the aluminium base were used; PAC (Poly Aluminium chloride, $Al_2O_3$ 17%) and C-210P (0.2%). After Jar test, PAC 26 mg/L and 0.2% C-210P 55 mg/L was decided as the optimum concentration of the coagulant according to zeta potential measurement. pH, alkalinity and viscosity were measured in all experiments and the data on sedimentation characteristics is analyzed by SDI, SVI sedimentation rate and solid flux. The SRF(Specific Resistance of Filtration) experiment was conducted with the result of single and dual injection system as the dewaterability experiment. As a result, the organic coagulant making large floc has good characteristics of sedimentation and agglutination. Also, it is observed that the organic coagulants injection has a better dewaterability efficiency of coagulants under the condition of the lowest SRF value, followed by dual and inorganic coagulants injection.

Multiple vertebral compression fractures are a rare condition and are a serious consequence of postpartum osteoporosis. This report describes the case of a 35-year-old woman who had given birth to her first child 2 months before the onset of pain. Magnetic resonance imaging showed compression fractures of 7 vertebrae. The patient was treated with both conventional, and Korean medicine methods including acupuncture and herbal prescriptions. The patient's progress was assessed using self-reported symptoms, scale scores and laboratory test results. Her pain was gradually alleviated and biochemical inflammation marker levels improved, but her functional status remained severely impaired. Clinical practitioners who treat women in the postpartum period must be aware of osteoporosis and potential vertebral fractures and need to consider Korean medicine as an alternative therapy to help such patients.

Background: To evaluate whether ${\geq}3$ adjunct acupuncture sessions accompanying embryo transfer, increases the chance of pregnancy amongst post-myomectomy women aged ${\geq}35$ years. Methods: This was a prospective study carried out at Nordica Fertility Center. Following written informed consent, 75 patients undergoing assisted reproduction therapy and who had good quality embryos, were age-matched and grouped into post-myomectomy (n = 24) and normal women who had no evidence of fibroids or previous myomectomy (n = 51). Between 1 and 3 sessions of acupuncture were performed on 6 post-myomectomy and 19 infertile women who had not undergone myomectomy, while > 3 acupuncture sessions were performed on 18 post-myomectomy and on 32 normal patients, approximately 25 minutes before and after embryo transfer. Results: A positive pregnancy test was defined as ultrasonographic evidence indicating presence of a fetal sac 6 weeks after embryo transfer. Of the 5 post-myomectomy women who were pregnant, only 1 (20.0%) received 1-3 adjunct acupuncture sessions whilst the remaining 4 (80.0%) received > 3 acupuncture sessions. Of the 11 normal pregnant women, 5 (45.4%) received 1-3 adjunct acupuncture sessions while 6 (54.5%) received > 3 adjunct acupuncture sessions. Conclusion: Pregnancy rates in infertile post-myomectomy women may be improved by > 3 adjunct acupuncture sessions.

Coagulation/precipitation process has been widely used for the removal of phosphate within domestic wastewater. Although Fe and Al are typical coagulants used for phosphate removal, these have some shortages such as color problem and low sedimentation velocity. In this study, both Fe and Al were used to overcome the shortages caused by using single one, and anionic polymer coagulant was additionally used to enhance sedimentation velocity of the precipitate formed. Batch experiments using a jar test were conducted with real wastewater, which was an effluent of the second sedimentation tank in domestic wastewater treatment plant. Response Surface Methodology was used to examine the responsibility of each parameter on phosphate removal as well as to optimize the dosage of the three coagulants. Economic analysis was also done on the basis of selling prices of the coagulants in the field. Phosphate removal efficiency of Fe(III) was 30% higher than those of Fe(II). Considering chemical price, optimum dosage for achieving residual phosphate concentration below 0.2 mg/L were determined to be 18.14 mg/L of Fe(III), 2.60 mg/L of Al, and 1.64 mg/L of polymer coagulant.

The purpose of this study was to analyze water treatment characteristics, including the efficiency of removing algae from water purification plants, by installing a demonstration facility for decontamination of algae, including natural algae remover injection equipment, in the water purification plant. Jar-test showed that the optimum injection of natural decontaminant was 20 mg/L. Of the water contaminant treatment efficiency of the intake and water purification plants, Chl-a averaged 74.0% elimination efficiency from $5.0mg/m^3$ to $1.3mg/m^3$ and the maximum treatment efficiency was 91.5% removal efficiency when the inflow concentration of Chl-a was $11.8mg/m^3$. In addition, 51.2% and 47.1% of the taste and odor indicator items, geosmin and 2-MIB, resulted from the overgrowth and decaying of algae, respectively, to identify toxic substances and odor reduction effects. In addition, elimination efficiencies of SS and Turbidity materials were higher than 70.0%. In the injection of natural algae remover, no effects such as sudden changes in water quality due to secondary reactions were found, and appropriate levels were maintained under water treatment conditions.

Two patients with sequelae of peripheral facial nerve palsy were treated with Facial Chuna Manual Therapy (FCMT) and acupuncture over 6 months. The House-Brackmann (HB) scale, facial nerve grading system 2.0 (FNGS), the scale of Peitersen, the scale of Murata, and the Numeric Rating Scale (NRS) were used to assess the effects of treatment. The HB scale, FNGS and NRS scores showed improvement for both patients (Case 1: HB scale 5 to 3, FNGS 4 to 2, NRS 10 to 5; Case 2: HB scale 5 to 3, FNGS 4 to 3, NRS 10 to 2.5) following 6 months of treatment. The scores for the Peitersen and Murata scales showed improvement over 6 months in Case 1 (Peitersen 2 to 1, Murata 10 to 7), but there was no change in Case 2 over the test period (4 months). FCMT and acupuncture may help patients with sequelae of facial palsy.
