Computed tomography is of prime importance in the diagnosis of epilepsy. In a previous study, one of the authors (Chang) reported that the proportion of organic lesion in epilepsy was approximately 49% according to CT examination. In this article, the authors studied the correlation of EEG and CT findings in 232 epileptic patients, who had been managed in Kyung-Hee University Hospital from October 1977 to March 1981. The patient population consisted of 155 males (66.896) and 77 females (33.2%). Age distribution was broad ranging from 3 months to 72 years and 75% of patients were below the age of 40. The types of epilepsy were centrencephalic epilepsy (145 grand mal and 2 petit mal) ; 64.5% (N=147) and focal epilepsy (6 Jacksonian, 12 T.L.E., and 67 others) ; 36.5% (N=85). Data were analysed and the following results were obtained : 1. There were no statistically significant differen ces in abnormal findings by using EEG ( N = 153, 65.9%) and CT (N=144,62.196) in total epileptic patients. 2. Abnormal CT findings in focal epilepsy (75.3%) was more frequent than that of centren cephalic epilepsy (54.4%). 3. According to the rough subdivision of lesion sites (left, right, or diffuse), concordance rate of sites of abnormal EEG and CT was significantly high (74.1%, p < 0 .01). 4. Focal slowings in EEG was associated with higher proportion of abnormal CT (81.2% ), as compared with focal paroxysms (29.4%).

Currently about 70000km public sewer was constructed in Korea. But, the condition is poor. And most of the sewers has whole functional or structural problems. The sewers are deteriorative and continuously required rehabilitation and renovation. Many sewage treatment plants were constructed and the capacities of them were increased in Korea. But, Inflow of underground water and Outflow of sewage from the faulty sewers decreased processing abilities of sewage treatment as 30-50% and polluted underground water. In the past times, the method for construction, renovation and rehabilitation to bring a solution to these problems was the existing excavation method that excavate a road, construct sewer and pave the road again. There were no problems in the excavation method at the past days which was low industrial society and easy conditions of traffic. Today, America, Japan and Europe are concerned about excavate construction come into being problems which are the high construction expenses, the loss of society cost, accident, pollution by industrial growth and the increase of the volume. So, advanced nations develop and supply new methods which are trenchless technology. In this research, we identified the characteristics of the sewers repaired with CIPP method one of the trenchless technologies used at present, and probed the characteristics of the sewers repaired with CIPP method after second damage by I/I test, Strength test and Flow test.

HEC-HMS모형의 Snyder합성단위도법을 이용한 매개변수 민감도분석

권순호(Soon ᅳ,Ho Kwon),정건희(Gunhui Chungt) 호서대학교 공업기술연구소 2015 공업기술연구 논문집 Vol.34 No.2

최근 우리나라는 기상이변으로 인한 가뭄 및 홍수 등의 재해발생이 빈번해지고 있다. 이러한 재해 피해의 최소 화를 위해 적절한 수자원관리는 매우 중요하다. 이러한 자연재해의 피해를 최소화하기 위해 강우와 유출관계를 규명해야 한다. 강우와 유출관계를 규명하는 일은 매우 복잡하여 하천에서의 유출량 추정은 하천 공간 정보의 부족으로 많은 어려운 문제점을 야기되고 있다. 그래서 본 연구는 미국공병단 수문연구소에서 개발한 HEC-HMS모형을 사용하여 대상유역의 매개변수 초기값을 조합하여 산정한 후 Snyder 합성단위도법으로 유출량을 산정하여 매개변 수에 대한 민감도분석을 하고자 한다. Recently, natural disasters caused by drought and food occurs more frequently. To cope w ith these disasters, water resources has to be managed properly and runoff should be calculated more accurately. Runoff calculation is very complicated because of the lack of information about the watershed and the complexity of the relationship in the transform from the rainfall. Therefore, in this study, HEC-HMS is applied to calculate runoff from a watershed and parameter sensitivity is investigated using Snyder synthetic u n it hydrograph.

Monitoring of diphenylhydantoin (DPH) serum level has become a subject of clinical interest for it’s usefulness in detecting noncom pliance, confirming suspected intoxication, evaluating inadequate control of seizure, and in determining the appropriate dosage. Sometimes ignorant uses of DPH have brought in difficulties in proper management of the epileptics before the close of l970’s in Korea, when the monitoring of the serum level became available and few reports have been published. The authors tried to investigate 100 epileptics, who have maintained DPH in Kyung Hee University Hospital,to confirm the serum levels of DPH in relation to daily dosage, dosage based on body weight, response to maintenance therapy, and toxic effects. And the following, results were obtained 1. The mean serum levels of the adult patients were 12.4 ± 12.2ug/ml in a group with DPH 200mg daily and 12.3 ± 7 .6 /ug /ml with 300mg daily, 10.6± 10.1ug/ml in a group with 4—4. 9 mg/kg/day, 12 .3 ± 6 .3ug/ml with 5—5. 9mg/kg/day and 12.4 ± 6.7ug/ml with 6—6 .9mg/kg/day. 2. Among the patients with 300mg daily, the mean serum level was 10.4 ± 8 .0ug/ml in a group with 4-4 . 9mg/kg/day and 12.7 ± 6.1 ug/ml with 5ᅳ 5 .9 mg/kg/day based on body weight. 3. About 45% were controlled completely with DPH maintenance below the level of 9.9ug/ml 26% in the range of 10—19.9/ug/ml and the mean serum level of the patients who were controlled completely was 10.2±8.5ug/ml So the serum levels could not be regarded as an absolute indicator of clinical efficacy in DPH maintenance. 4. Nystagm us and ataxia were noticed in 4 patients and the serum levels were below effective therapeutic range in 2 patients among them.

Computed tomography (CT) is a new diagnostic radiologic procedure for defining cranial and intracranial structures and provides a fresh approach to the study of epilepsy. Since the introduction of CT, the authors have had the opportunity to investigate 189 patients in whom the clinical diagnosis of a epilepsy was suspected and then who had been performed brain CT in the Kyung-Hee University Hospital from Oct. 1977 to May 1979 and have analized the CT findings in epilepsies. The sex distribution of the patients took 66. 1% (n=125) of male and 33.9% (n=64) of female. The most common age group was below ten years (29.1%) followed by the teens (25.4% ), the thirties (16.9% ) and the twenties (15.9% ). The results were as follows. 1. With regard to the types of epilepsy, centrencephalic type (grand mal: 157,petit mal : 2) was 84.1 % (n=159) and focal type (Jacksonian epilepsy:4,T.L.E .:5, others:21) was 15.9% (n=30) of whole patients. 2. In grand mal type, 38.2% slowed abnormal CT findings and 61.8% normal. Abnormal CT revealed cortical atrophy(35% ), infarction (23.396) ttumor (21.7% ) and others (2096). 3. In petitmal type, all (n = 2 ) showed normal CT findings. 4. In the cases of focal epilepsy, 53. 396 showed abnormal CT findings and 46.7% normal. Abnormal CT revealed cortical atrophy (37.5% ), tumor (31.3%) pineal gland calcification (12.596), infarction (12.5% ) and paragonimiasis (6.3% ).

The authors experienced and reported a 21-years-ᄋId female patient who was severely deteriorated following uncontrolled grand mal seizures lasting for more than 10 years. At first petit mal seizure was developed at the age of 7 and then the pattern of seizure was changed to grand mal type. She had achieved normal physical and mental developments till the appearance of grand mal seizure, but she has become deteriorated gradually with repeated seizures of 7-8 times a day. Deteriorations have been progressed markedly and finally she became a severely deteriorated dementic like a 1-2 years old baby since the age of 19. She could not walk and speak a word except “mamma” when she was brought to emergency room. Diffuse scattering of slow waves and spikes were noticed on the E.E.G. and moderate degree of cerebral atrophy on computerized tomography of the brain. With the beginning of anticonvulsant therapy, the seizure was controlled almost completely and hence her mental and physical states have become improved steadily during 9 months of follow-up treatment. And at the end of follow-up period, she became to be able to speak freely with others and carry out usual life activities with minimal limitations. In this case, we can presume that her severe deterioration have been resulted primarily from long-standing hypoxia of the brain due to repeated clinical and subclinical seizures. But the possibilities that the other factors such as adverse effects of anticonvulsants, folate deficiency and social factors could play a role in part can not be excluded entirely. And also we call attention to the fact that epileptic deterioration can be prevented through adequate control of seizures and support of epileptic individuals by various means.
