Enuresis is relatively common disorder, affecting approximately 20% in 5 year old children. Although the spontaneous cure rate has been reported to be about 15% per year, 1% at the age of fifteen have still bed wetting problems. 50 to 80% of enuresis is reported to be related to physilolgic or psychlolgic cause. Only eneuresis caused by organic disturbance occupies 1 to 205 at most. A variety of therapies have been attempted in most patients including water deprivation in the night, eneuresis alarm clock, and drugs such as imipramine or desmopressin, without success or with side effects. The follow up study was carried out to evalute the efficacy of Kamisamki Tang on eneuresis in 17 patients. They were 9 females and 8 males ranged 4 to 54 years old. The extract of Kamisamki Tang was administered three times a day about 30 minutes after meal. The patients kept water deprivation in the night, urine voiding before sleep, and also did bladder retension exercise and conscious stream interruption exercise. Three patients did not have wetting problems after administration. Good result was appeared in 6 patients and fair in 4. Other 4 patients were not responded. The three with excellent effect were administered for mean 10.0 days, 4 with good effect were for 16.7 days, 4 with fair were for 26.7 days and 4 with poor effect were for 27.5 days. These result suggests that Kamisamki Tang could be applied on eneuresis effectively.

The prevalence of disease is affected by cultural factors. Changing cultural and social pattern may modify patterns of disease. Today majority of labor force in rural community is elderly population with a concomitant increase in woman. We investigated prevalence of problems in rural population utilizing oriental medical clinic in Changsan-myon, Shinan-gun, Chunnam. The majority of patients in this area were female and in the 40 to 60s. Muscoskeletal problems had the highest incidence. Low back pain was leading complaints in the muscoskeletal problems and knee pain was the most common complaints in the digestive problems, headache in the neurologic problems. cough in the respiratory problems, hypertension in the circulatory problems, ear problems in the sense organ problems, pruritys in the dermatologic problems, leukorrhea and postmenopausal syndrome in the gynecologic problems, and dysuria and enuresis in the urinary problems. These results suggest that oriental medical physicians have attention to health care and management of the expanding population of elderly and female patients with high incidence of muscoskeietal problems in the rural community.

Background and Objectives: The maze procedure is effective in restoring sinus rhythm (SR) in patients with atrial fibrillation (AF). We compared the left atrial mechanical function (LAMF) of patients whose rhythm was converted to SR after maze procedure with that of patients whose rhythm was not converted to SR and determined if preoperative left atrial volume index (LAVI) and immediate postoperative LAMF could predict conversion of AF to SR. Subjects and Methods: We prospectively evaluated 80 patients with AF treated with the maze procedure between March 2005 and February 2007. LAMF was assessed by looking at left atrial ejection volume (LAEV) and ejection fraction (LAEF) during echocardiography before, 2 weeks after, and 6 months after the procedure. Results: Of the 80 enrolled patients, 71 were converted to SR after the maze procedure (SR group), and 9 were not converted to SR (AF group). There were no significant differences in age, sex, hypertension, diabetes mellitus, renal failure, stroke, thyroid dysfunction, or smoking history between the groups. Pre-operative LAVI (p=0.010) was a predictor of conversion of AF to SR. LAEF gradually increased in the SR group during follow-up, but not in the AF group. Conclusion: LAMF recovered in the SR group after the maze procedure, irrespective of clinical presentation and initial LAMF. Preoperative LAVI predicted SR conversion.

The purpose of this study is to analyze the 3D geoinformation of a reservoir using a UAV and an echo sounder for effectively monitoring drought conditions in the reservoir. Water surface boundaries were analyzed using RGB imagery obtained by the UAV. Depth information was collected with the echo sounder, which was adapted for unmanned boats in this study. The obtained 3D geoinformation was analyzed using spatial interpolation methods. The maximum depth of the reservoir was determined as 3.2 m. The reservoir bed information differed according to the precision of unmanned boat operation; therefore, improvement in unmanned boat operation is required to accurately analyze the 3D geoinformation of a reservoir. 본 연구는 저수지의 가뭄현상의 효율적인 모니터링을 위해 UAV 및 음향측심기를 활용하여 저수지의 3차원 지형정보를 분석하였다. UAV 영상정보 취득을 통해 저수지 수면 경계 분석하였고, 무인보트에 탑재된 음향측심기에서 취득된 수심정보를 획득하였다. 그리고 공간내삽기법을 통해 3차원 지형정보를 분석하였다. 분석결과, 저수지의 수심은 최고 3.2 m로 나타났다. 저수지의 하상은 무인보트 운용의 정밀성에 따라 결과값의 차이가 있는 것으로 나타났다. 따라서 보다 정밀한 저수지의 3차원 지형정보를 분석하기 위해서는 무인보트의 자동항법기능 추가 등 운용방법에서 개선이 필요할 것으로 보인다.

Infrared thermographic imaging visualizes noninvasively various abnormal condition by detecting the skin temperature. As the imaging represents the objective condition by the changes in blood flow under the control of autonomic nervous system, it is used to diagnosis and monitor the lumboscral radiculopathy. And asymmetry is important in the diagnosis of disc herniation. The most common type of disc herniation occurs psoterolaterally. This frequently causes nerve root compression leading to a radiculopathy in the distribution of the involved nerve root, most of which also provoke the asymmetric changes in thermography. Central disc herniation, which accounts for 5% to 35% of disc herniation, is typically associated with low back pain. But radiculopathy is usually abscent unless central disc heriniaton is large enough to cause compression of the cauda equina. To evalute the diagnostic value of the thermographic imaging in the diagnosis of central disc herniation, the imaging of 15 normal subjects and 48 patients with central disc herniation documented by CT scan were analyzed. The patients had either bilateral radiculophathy or no radiculopathy. The imaging of patient group with non rediculopathy did not show any significant thermal difference to control. While bilateral radiculopathy group reveled hypothermic pattern compared twith control. Thermal difference between left and right side did not present any significance in non radiculopathy group but hypothermia in bilateral radiculopathy group. Large herniation group demonstrated hyperthemic pattern while the others showed no significant change. Cranial caudal thermal difference did not show any difference between experiment groups. These results shows that infrared thermographic imaging can be used central disc herniation with bilateral radiculopathy, while it seems to little useful on the diagnosis of non radiculopathic disc herniation.

The purpose of this study is to minimize damage of chemical accidents through the appropriation analysis of evacuation facility position focused on Ulsan metropolitan city. For analysis, informations such as pollutant release and transfer registers(PRTR), population census, and evacuation facilities were used. After then, damage assessment of chemical accidents, accessibility and appropriation of evacuation facilities were analyzed. Damage of chemical accidents is high in around 5km of industrial complex there is dense of chemical facility and population. Evacuation facilities were mainly situated in hazard area of chemical accidents, but accessibility of evacuation facilities was vulnerable in chemical plant neighborhood. Therefore, safety check of deteriorated plants is important for prevention of chemical accidents. Also, effective evacuation plan considering capacity and scale of evacuation facilities will be established. 본 연구는 울산광역시를 대상으로 화학사고에 대비한 대피시설 위치의 적정성을 분석하여 피해 최소화를 위한 방안을 연구하였다. 연구방법은 화학물질 배출 및 이용량 자료와 인구센서스 집계구 자료, 대피시설 위치정보 등을 활용하여 화학사고 위험성 평가와 대피시설의 접근성을 분석하였다. 이를 통해 대피시설 위치의 적정성을 도출하였다. 화학사고 위험성은 석유화학공장과 인구가 밀집된 석유화학공단지역 인근 5km 이내에서 높았다. 대피시설은 대부분 화학사고 위험지역에 분포하고 있으나, 석유화학공장 인근지역에서 대피시설의 접근성이 취약한 것으로 나타났다. 따라서 우선적으로 화학사고 예방을 위해 노후화된 공장시설의 안전점검도 필요하지만, 대피시설의 수용 인원, 규모 등을 고려하여 보다 효과적인 대피방안을 마련해야 될 것이다.
