Objectives: The purpose of this study is to evaluate the effectiveness of electroacupuncture on heat sensation of the feet of a 61-year-old female patient with restless leg syndrome. Methods: Electroacupuncture was performed at four acupoints (KI3 (太谿), KI6 (照海), LR3 (太衝), LR2 (行間)) selected to reduce heat sensation in both feet. The patient's symptoms were assessed using the VAS (Visual Analogue Scale), the SF-MPQ (short-form McGill Pain Questionnaire), and the IRLS (International Restless Legs Scale). The treatment was performed from April 20, 2010 to April 24, 2010. Results: During five sessions of electroacupuncture treatments, the VAS, SF-MPQ, and IRLS scores improved throughout the treatment period and afterwards. Conclusions: The results suggest that electroacupuncture at KI3(太谿), KI6(照海), LR3(太衝), LR2(行間) can be effective for reducing hot flush in both feet.

In this study, theoretical analysis and finite element analysis of the behavior of membrane (such as resonance frequency, membrane deflection, collapse deflection and collapse voltage)in thc capacitive micromachined ultrasonic transducer (cMUT) were performed. The design parameters of the cMUT were estimated and are the dimension and thickness of membrane, thickness of sacrificial layer, thickness and size of electrode, size of active element and so on. The resonance frequency of the membrane increased as the thickness of the membrane increased but decreased as the diameter of the membrane increased. The deflection of the membrane increased as d-c bias voltage increased. The collapse voltage of the membrane was predicted.

Generally, the totally paralyzed face can never be made normal by any of the current methods of reconstruction. Careful selection of patients based on sound judgment of what can and cannot be achieved by the proposed surgical technique is paramount to a successful operation and a satisfied patient. The results are related to time of delayed between injury and repair : the shorter the delay the better are the results. The objectives in correcting facial paralysis are to achieve normal appearance at rest ; symmetry with voluntary motion ; control of the ocular, oral, and nasal sphincter; symmetry with involuntary emotion and controlled balance when expressing when expressing emotion ; and no significant functional deficit secondary to the reconstructive surgery. It must be employed a number of concepts, for treatment of the paralyzed face by surgeon, depending on the cause, time interval, and wound characteristics, as well as the availability of and necessity for neuromuscular substitution. Nerve grafts, crossovers, muscle transfers, free muscle and nerve-muscle grafts, micronuerovascular muscle transfers, and regional muscle transpostion are the principal methods being developed. We applied the tmporal musle transposition for reanimation of unilatrally paralyzed faces for long times on two patients. The results of muscle transposition can be enhanced by the patient's learning to activate the transposed muscle by voluntary effort, and are best in patients who are motivated to learn the necessary motor-sensory coordination techniques.

Adsorption characteristics of three endocrine disruptors, amitrol, nonylphenol, and bisphenol-A, were evaluated depending on the type and service duration of activated carbon (AC). Bituminous coal-, wood-, and coconut-based coals were tested. Bituminous coal-based AC (BCAC) had the greatest sorption capacity for the three chemicals tested, followed by wood-based AC (WAC) for nonylphenol and coconut palm-based AC (CAC) for bisphenol-A. During the column test, amitrol removal efficiency increased over time, indicating that hydrophilic endocrine disruptors are biodegraded in the AC column. Removal efficiencies of hydrophobic compounds such as nonylphenol and bisphenol-A decreased over time since the main removal mechanism was adsorption. The order of the amitrol removal was: BCAC-5.9 yr , CAC-3.1 yr > BCAC-2.2 yr > BCAC-virgin > CAC-virgin > WAC-virgin > WAC-3.1 yr. In general, used AC had greater removals than virgin AC. The order of the bisphenol-A removal was: CAC-virgin > BCAC-2.2 yr > CAC-3.1 yr > WAC-virgin > BCAC-5.9 yr > WAC-3.1 yr. The order of the nonylphenol removal was: BCAC-virgin > WAC-virgin > CAC-3.1 yr ,WAC-3.lyr> BCAC-2.2 yr > BCAC-5.9 yr > CAC-3.1 yr. Bituminous coal AC performed the best over time. Endocrine disruptors such as these three compounds appear to be removed effectively by activated carbon through biodegradation and adsorption. Wood and coal based among the virgin ACs and 3.1 years used wood base among the used ACs appeared the lowest carbon usage rate(CUR) for nonylphenol removal by prediction model. Virgin and used coconut base ACs except BCAC had the lowest CUR for removal Bisphenol-A. Biodegradation of nonylphenol and Bisphenol-A did not occurred during the 9,800 bed volume experiment period. BCAC had the highest biodegradation capacity of 46% for amitrol among virgin ACs and the used coal based ACs had 33-44% higher biodegradation capacity than virgin's for amitrol so biodegradation is the effective removal technology for hydrophilic material such as amitrol.

이 연구는 1993년도에 우리나라의 연간 슬러지발생량이 약 3500만m³에 이르고 있으며, 이들 대부분이 매립되고 있다. 그러나 매립부지의 확보가 점점 어려워 지고 있으며 아울러 매립처분비용도 상승하고 있기 때문에 oil화, 퇴비화등으로 재자원화 하는 방법과 소각후의 소각회를 유효이용하는 방법 등이 연구 개발되고 실용화되고 있다. 슬러지의 oil화는 현재 연구단계에 있으나 앞으로 슬러지의 유효이용기술로서, 가장 좋은 방법이 되리라 기대되고 있다. 그러나 소각후의 소각회의 이용방법은 현재 일본등에서는 실용화 되어 건설자재 등으로 다양하게 이용하고 있다. 우리나라에서도 서울시 등을 비롯한 대도시에서는 하수처리장에서 발생하는 슬러지를 소각한 후에 소각회를 건설 자제용으로서 지자체의 공사에는 반드시 사용하도록 하는 제도를 만든다면 유효이용방법으로 충분한 타당성이 있을 것이다. 이때 소각방법으로는 용융소각방법이 보다 효과적일 것이다. With increasing sewage and wastewater sludge, it has become difficult to dispose the sludge by landfilling and ocean dumping. To solve this problem, efforts have been made to delelop sewage and wastewater sludge utilization technologies in many advanced countries. Some technologies have already been developed; conversion of sludge to compost and fuel, producing artificial light-weight aggregate from ashes. This paper describes the technical status of sludge utilization technologies.

Granulocytic sarcoma, a rare extramedullary solid tumor arising from early myeloid precursors, is capable of invading the meninges or the brain parenchyma. The tumor may occur during or after the onset of systemic myelogenous leukemia. On rare occasions, the tumor may evolve before the onset of systemic myelogenous leukemia. Children are affected more often than adults, but sex is not related. Although no definite target area of the brain can be demonstrated, there may be some predilection of the tumor for the posterior fossa. The authors report a case of 4-year-old-boy with granulocytic sarcoma occuring in the posterior fossa presenting with gait disturbance and torticollis. The patient was treated by surgical removal of the tumor, thereby avoiding the potentially lethal complication of a posterior fassa mass. This rare case is reported together a review of the literature.

The presence of traumatic subarachnoid hemorrhage on the initial computerized tomographic scans has been known to be associated with worse results. By means of a simple and reliable computerized tomographic grade system proposed by Greene and his colleagues, prognostic factors of the traumatic subarachnoid hemorrhage was significantly related to clinical outcome at the time of discharge from acute hospitalization. Between February 1992 and August 1995, 3975 patients were admitted to our department of neurosurgery due to head injury. Clinical data were retrospectively reviewed to ascertain the relationship of the thickness of traumatic subarachnoid hemorrhage, its location, evidence of mass lesion(s), midline shift, obliteration of the basal cistern, and cortical sulcal effacement to outcome. Additionally initial Glasgow coma scale score, arterial gas study systemic blood pressure and prothrombin time were also analyzed for the same purpose. Among 3975 head-injured patients. 213 patients were identified to have traumatic subarachnoid hemorrhage on the initial computerized tomographic scan. Among 213 traumatic subarachnoid hemorrhage patients, the patients treated with calcium channal blocker(32 patients) and 3 patients lost to follow-up were excluded from this study for a total of 178. The computerized tomographic scan findings were divided into a 3 grade system : Grade 1 indicating only traumatic subarachnoid hemorrhage. Grade 2 indicating traumatic subarachnoid hemorrhage with mass lesion(s). Grade 3 indicating traumatic subarachnoid hemorrhage with mass lesion(s) and midline shift. All these data were compared to Glasgow outcome scale on discharge, and arbitarily these were divided into the good(good recovery and moderate disability) and the bad(severe disability, vegetative state and death). The authors conclude that the contributing factors to outcome at discharge were as follows : 1 midline shift(p=0.002), PT≤70%(p<0.001), obliteration of the basal cistern(p=0.001) and cortical sulcal effacement(p=0.001) were shown to the statistically significant. 2. initial computerized tomographic grade contributed to outcome at discharge.
