위축뇌탈출증(atrectic cephalocele)은 중앙의 두피하부에 있는 피부로 덮힌 병변으로서 수막과 아교세포나 중추신경계 조직의 잔유물들을 포함한다. 수직동이 없거나 잔유물로 남아있는 경우 낫형동(falcin sinus)이 다시 관류하게 되어 정맥의 배출이 가능하게 된다. 위축된 뇌탈출증 또는 지속적인 낫형동은 소아에서 주로 기술되어 왔으며, 성인에서는 매우 드문 병변이다. 저자들은 성인에서 자연퇴화된 위축뇌탈출증이 지속적인 낫형동을 동반한 매우 드문증례를 보고하고자 하며 MR영상과 MR정맥조영술은 정확한 해부학적 묘사와 진단에 유용하였다.

Acute viral meningitis and myositis are rare complications of varicella-zoster virus (VZV) reactivation. A 71-years-old immunocompetent man, who presented with lower back pain radiating to the left lower extremities, developed vesicles on the L5 dermatomal area. The next day, he had complained of aberrant vesicles on the trunk, face and scalp, with generalized myalgia, headache and dizziness. He was confirmed with VZV meningitis and myositis, as demonstrated by the presence of VZV DNA in the blood and cerebral spinal fluid using a polymerase chain reaction (PCR) amplification. PCR has been used in patients with a VZV infection associated neurological symptoms, and provides a useful tool for the early diagnosis of VZV-associated neurological disease. The patient was treated with bed rest, with intravenous acyclovir for the VZV infection, and intravenous Patient-controlled Analgesia for pain management and the prevention of postherpetic neuralgia. When he visited the outpatient department 3 months later, the skin lesion, leg pain, headache and myalgia had all improved, without sequelae. Here, this case is reported, with a discussion of the relevant literature on its diagnosis and management.

Ultrasonographic examination in the obstetrics not only makes easy of the diagnosis of Hydrocephalus, placenta previa, anencephalus and ectopic pregnancy, etc, but also guaranteed its excellence in the diagnosis of women gynecology disease. Especially in case that it doesn't affect radiation hazard on the embryo, its efficiency keeps increasing and it is spotlighted to many clinic doctors. Even though in general hospital we often observe congenital hydrocephalus in Med. Dept. which entirly undergoes the medical examination to the insured, we don't observe even the women delivered with child and it is very difficult to find a rare congenital hydrocephlus throughout other present insurance companies. We inspected a congenital hydrocephalus, which other medical equipments of present insurance companies have many difficulties in the medical examination, accompanied by meningoencephalocele by ultrasonic diagnosis. We analyzed and compared the data by ultrasonic diagnosis with that of surgical diagnosis and the results are follows; 1) We could correctly describe meningoencephalocele by ultrasonic diagnosis. 2) It was able to be diagnosed in LMP 22 weeks. 3) BPD has about 10 mm higher than normal value in LMP 22 weeks. 4) Dilatation of lateral ventricle was observed in LMP 22 weeks. 5) As paralled with ultrasonic diagnosis in pregnancy medical examination, accepting declines including the risk rate can be restrained.

One hundred patients requiring appedectomy were studied to determine the minimal effective dose of intrathecal morphine for postoperative analgesia. In double-blind fashion, groups of 20 patients received either 0.02 mg (group I), 0.04 mg (group II), 0.06 mg (group III), 0.08 mg (group IV), or 0.10 mg (group V) intrathecally with 10% dextrose in water 2 ml. Group II to group V patients reported significantly less postoperative pain than group I patients as assessed by the Prince Henry pain scale and required significantly fewer analgesic interventions for 24 hours. The incidences of vomiting and pruritus were considerably high in all groups, but none of them required any treatment. The incidence of urinary catheterization due to urinary retention in group II to V was twice that of group I. No clinically evident respiratory depression occurred in any of the subjects. In conclusion, intrathecal morphine administration of 0.04 mg proved effective in reducing postoperative analgesic requirements and in eliminating postoperative pain following appendectomy and was not associated with significant side effects. It is very likely that such low dose intrathecal morphine would also work in other operations.

금속분말을 연료로 하는 연소기 개발에 있어 발생하는 문제점 중에 하나는 알루미나 slag 처리이다. 연소기 내부에 Water film을 형성시킴으로써 금속분말 연소기의 문제점을 해결할 수 있을 것으로 기대한다. 이를 위한 선행연구로 water film의 형성 조건에 대한 실험을 수행하였다. 실험 모델에 대하여 물 분사 속도가 증가할수록 원형 모델에 대한 water fim 각도가 작아져, 약 10 m/s이상에서 완전한 water film이 형성되는 것을 알 수 있었다.

장티푸스는 10-15%에서 수막염, 폐렴, 심근염, 간염, 골수염, 파종성 혈관내 응고병증등의 심각한 합병증을 유발할수 있다. 소아에서 장티푸스 병발 후 신장에 발생되는 합병증은 국내외 모두 매우 드물다. 우리는 장티푸스 병발후 단백뇨, 고혈압, 신기능 저하가 동반된 급성 사구체 신염 케이스를 경험후 보고하는 바이다. 이 케이스는 대변 배양검사에서 병원체를 확인할 수는 없었지만 상승하는 Widal 수치로 장티푸스를 진단할 수 있었다. 장티푸스는 유병률은 감소하였지만 고열이 있는 경우 여전히 고려해보아야 하는 중요한 질환이다.

Adequate relative humidity is needed in the common living space, for human health, and industrial space, for maintenance and efficiency. Evaporative humidifier systems generally have slow response tendencies of air loads, but relatively low initial investment and maintenance costs. Humidification efficiency in the evaporative humidifier is dependent mostly on the shapes and arrays of humidifying modules. So, we tried to apply the computational fluid dynamics to the evaporative humidifier systems, and studied the humidification efficiency of evaporative humidifiers, through the outlet air conditions.

PURPOSES : This study aims to evaluate the road safety of the super-elevation transition section of a left turn curve and suggest the minimum longitudinal grade of a super-elevation transition section to be used before and after a left curved section. METHODS : We evaluated the road condition by means of the safety-criterion-evaluation method involving side friction factors, and then solve the problem by introducing the minimum longitudinal grade criterion based on conditions described in the hydraulics literature. RESULTS : It was calculated that when a road satisfies hydroplaning conditions, the difference between side friction assumed and side friction demanded is less than -0.04. In this case, the safety criterion for the condition is unsatisfied. Conversely, when a road is in a normal state under either wet or dry conditions, it was calculated that the difference between side friction assumed and side friction demanded is more than 0.01. Thus, the safety criterion for this condition is found to be satisfied. After adjusting the minimum longitudinal grade applied to a super-elevation transition section, the hydroplaning condition can be eliminated and the safety criterion can be met for all sections. CONCLUSIONS : It is suggested that a minimum longitudinal grade should be provided on super-elevation transition sections in order to prevent hydroplaning.

b형 헤모필루스 인플루엔자균 예방접종이 시행된 이후 b형 헤모필루스 인플루엔자균에 의한 감염률은 급격히 감소하였으나, non-b형 헤모필루스 인플루엔자균에 의한 감염의 비율이 증가하는 추세이다. 대뇌 정맥동 혈전증은 드물지만 세균성 수막염의 합병증 중 하나로 발생할 수 있다. 대뇌 정맥동 혈전증이 동반된 f형 헤모필루스 인플루엔자균에 의한 뇌수막염 환자를 진단 및 치료하였기에 보고하는 바이다.
