The purpose of this study is to report the patients with common peroneal nerve palsy, who improved by motion style treatment.(M.S.T.) The clinical study on 2 case of patients with herniation of nucleus pulposus, L4-5, L5-S1 combined foot drop, who had been hospitalized in Ja-Seng Oriental Hospital. We checked the motor grade and subjective improvement at interval of 3days under the treatment of M.S.T. After 2-3 weeks of treatment, the movement and power of ankle joint improved to nearly normal range. The subjective improvement was 70% compared with Rt. ankle and range of active motion increased from Gr.1-2 to Gr.4

The purpose of this study was to develop a portable and convenient closed-loop contrel type electrical stimulator for patients with foot drop. This system restores walking movement as well as prevents from atrophy or necrosis of lower limb muscles and increases blood circulation in hemiplegic patients caused by traffic accident, industrial disaster or stoke. This system detects the changes of the ankle joint angle during walking, and then controls the stimulus intensity automatically to maintain the programmed level of the ankle joint angle. Also, this automatic system controls the stimulus intensity which is affected by increased electrode impedance resulting from long time use. The system detects the joint angle by an optical sensor and includes modified PID control which adjusts the stimulus intensity if the joint angle deviates from the preset value. Stimulus parameters are 30~80 volt, 40 Hz, and 0.2 ms. The system was applied to five hemiplegic patients for 42 days. Duration of stimulation was 15 min/day for the first week and then the duration was gradually increased to 30, 60, 90 and 120 min/day. The muscle force was increased up to 29.7%, muscle fatigue was decreased compared with the level before stimulation and the pattern of locomotion was improved. These results suggest that the electrical stimulator with closed-loop control type is more convenient and effective in restoration of locomotion of patients with foot drop than open-loop system.

The polycyclic aromatic hydrocarbon (PAH) content in sewage sludge and in farm soils were determined by gas chromatography linked to mass spectrometry (GC/MS) with use 2-ethylantracene as internal standards. Twelve PAH were identified in both sludges with naphthalene ($0.78{\mu}g/g$) being the most predominant in industrial sludge and pyrene ($0.26{\mu}g/g$) in municipal sludge. The total PAR content in industrial sludge and in municipal sludge were $1.74{\mu}g/g$ and $1.19{\mu}g/g$ respectively. PAH were contained in paddy soils and the concentration were very low in the range of $0.01-0.04{\mu}g/g$. The total PAH content in industrial and in municipal sludge were about 9.2 times and 6.3 times greater than in paddy soils ($0.19{\mu}g/g$).

The Foot drop is led by the conditional palsy of dorsal flexor according to some causes. In this case, it is caused by peroneal nerve palsy. It brings the difficulty in waking and standing up. We observed 2 cases of patient with Foot drop. Two patients were treated by the same method and treatment was performed by means of electroacupuncture(2-4Hz frequency, intensity was adjusted so that localized muscle contraction could be seen). As the result, symptoms are improved.

Objectives: The purpose of this study is to evaluate the clinical effects of Muscle Energy Technique (MET) for peroneal nerve palsy after normal delivery. Methods: Two patients with peroneal nerve palsy were treated with acupuncture, moxibustion, cupping and MET. MET was performed in piriform, gluteus medius, anterior tibial and adductor muscles. To evaluate the effect of MET, we analyzed Ankle dorsiflexion range of motion (ROM), Manual Muscle Test (MMT), Numerical Rating Scale (NRS) and Ankle Hindfoot Scale (AHS). Results: In Case 1, ROM score was changed from −5 to 20, and MMT score was changed from 0 to 4. NRS score was changed from 5 to 1, and her AHS score was changed from 54 to 94 after treatment. In Case 2, ROM score was changed from 0 to 20, and her MMT score was changed from 1 to 5. NRS score was changed from 4 to 1, and her AHS score was changed from 64 to 97 after treatment. Conclusions: MET may be a useful treatment for patients who, shortly after childbirth or while breastfeeding, strongly refuse to treat the irritation.

This study was to evaluate a case of foot drop treated with placenta pharmacopuncure. After thirteen times of treatment, I evaluated this case by the angle of dorsiflexion, the total sum of gaiting points, the time of heel standing. As a result of evaluation, the angle of dorsiflexion, total sum of gaiting points, time of heel standing were improved. The placenta pharmacopuncture can be used for foot drop and other peripheral nerve palsy.

In order to evaluate the levels and distribution patterns, the concentrations of PAHs and chlorophenols were investigated in sludge samples discharged from 6 WWTPs located along Nak-dong river and 7 STPs in Busan, Korea. Levels of 16 PAHs and 19 chlorophenols in sludge samples ranged from 1.28 to 44.9 mg/kg dry wt. and from 213 to 3,850 $\mu$g/kg dry wt., respectively. Levels of PAHs in sludge samples except I5 and S4 were detected lower than those of previous studies. The distribution patterns of PAHs and chlorophenols varied with industrial wastewater sludge samples because industrial wastewater sludge had different industrial input sources. However, the distribution patterns of PAHs and chlorophenols in sewage sludge were pretty similar. Phenanthrene, fluoranthene and pyrene were dominant and the fractions of these 3 PAHs relative to 16 PAHs in sewage sludge ranged from 30.8 to 50.7%. 2-chlorophenol is dominated in most sewage sludge samples and the fraction ranged from 36.0 to 66.8%.

The purpose of this study is to the distributive property of organic pollutants in effluents of domestic sewage treatment plants around Youngsan River using simultaneous analysis method of 310 chemicals. The numerous organic pollutants were detected in five sampling sites, and the major chemicals were pesticides, CH type chemicals such as benzenes and polycyclic compounds, ande CHO type chemicals such as phenols and phthalates. About 14 pesticides were detected in the effluent and most of them were found in summer. 1-Chlorobenzen and p-octylphenol were frequently detected in the concentration range of $0.52{\sim}0.61\;{\mu}g/L$ and $0.04{\sim}0.89\;{\mu}g/L$, respectively. Moreover, 18 kinds of endocrine disrupters include diethylphthalate were detected in effluents. From the results of this study, therefore, we confirmed that the pesticides, CH and CHO type chemicals in domestic effluents throughout Youngsan River are required specific regulation.
