The need for rapid diagnosis and treatment of life-threatening thoracic and intra-abdominal injury result in controversy over the appropriate triage of unconscious blunt trauma patients. To aid in early decisions for these patients, a prospective analysis of 98 patients with glasgow coma scale(GCS) scores≤8 was undertaken. Although intra-thoracic and intra-abdominal injuries were frequently identified based on systolic blood ressure, the use of clinical signs alone resulted in more missed injuries than did using the emergency ultrasonography. In normotensive patients(n=34), intra-thoracic injuries was identified in one patient(2.9%), and intra-abdominal injuries were in 7 patients(20.6%). In shock(systolic blood pressure<90mmHg) Pa-tients(n=64), thoracic injuries and intra-abdominal injuries were diagnosed in 8(12.5%) and 27 patients(42.3%), thoracic and abdominal combined injuries were identified in 11 patients(17.2%). The sensitivity, specificity, and accuracy of emergency ultrasonography were 96.3%, 91.7%, 94.9%. This study suggests that all unconscious trauma patients undergo immediate emergency ultrasonography to prevent missing life-threatening injuries.

In order to investigate that blood lead levels of lead exposed workers is associated with decreased performance in neurobehavioral tests in adults, we investigate 78 workers in a battery industry. Three items among neurobehavioral core test battery of World Health Organization, including digit span, Santa ana dexterity, digit symbol were administered to workers occupationally lead exposed workers by operational guide for the WHO neurobehavioral core test battery. Blood lead (PbB) and zinc protoporphyrin in whole blood (ZZP) were selected as an index of lead exposure. Detailed occupational history such as exposed agent, age, work duration, smoking and drinking habits, were recorded as confounding factors. After controlling age, the results of digit span and digit symbol among the neurobehavioral tests were significant contributed by PbB.

Vesicovaginal fistula is a distressing complication which may follow hysterectomy, prolonged labor, chemical cauterization due to uterine prolapse, radiation therapy and cervix cancer. The management of vesicovaginal fistula still remains controversial in regard to the type of approach and timing of repair but the classic opinion is to wait 3 to 6 months to allow the surgical inflammatory reaction to subside. We experienced 4 cases of vesicovaginal fistula which were as follows; Case 1: 51-year-old The vesicovaginal fistula, about 3.0cm in diameter, after laparascopic hysterectomy 15 days ago was repaired with interposition of a gracilis muscle flap via the transvaginal route. Case 2: 38-year-old The vesicovagianl fistula, about 2.5cm in diameter, after Cesarean section 5 years ago was repaired with interposition of the omental flap via the transabdominal route because she had been accompanied by an overian cyst. Case 3: 46-year-old The vesicovaginal fistula, about 2.5cm in diameter, after manual self abortion at home 30 years ago was repaired with interposition of fibro-fatty tissue in labia via the transvaginal route. Case 4: 43-year-old The vesicovaginal fistula, about 2.0cm in diameter, after prolonged labor 12 years ago was repaired with interposition of the fibro-fatty tissue in labia via the transvaginal route. There noted no complications or recurrence during the minimal 1 year follow-up.

To improve the therapeutic method for mastitis, treatment effect of chitosan pharmacopuncture was examined in three milking goats(A,B and C). Mastitis was artificially induced in two milking goats(A and B) and one goat(C) was naturally infected case with mastitis. The acupoint used was Yang-Ming and chitosan suspensions(provided from Tottory University, Japan: 30㎎ of chitosan/㎖)were injected to the acupoint with 5㎖/time for 3 days, respectively. As for the change of somatic cells in milk along with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in all udders of B. In addition, as for the change of total leukocyte counts of peripheral blood with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in B and C except A which showed a increasing tendency until on the 7th day. In the change of neutrophil/lymphocyte(N/L) ratio, increasing tendency was seen in A and C but increasing tendency after slight decrease was observed in B. Further, in the change of serum total protein and A/G ratio, serum total protein content was decreased after slightly increase on the 3rd day in A, and they were decreased after increase until on the 7th day in B and C, respectively. As for the change of A/G ratio, different pattern increasing tendency was shown in A, B and C.

The smectite-rich clays were found locally in Paleozoic calcareous sedimentary rocks in the Samcheok area. Their occurrences were investigated in detail, and the physico-chemical properties of the clays were also determined by X-ray diffraction, chemical analysis, thermal analysis and cation exchanging experiment. The smectitie clays occur as the fissure filling dyke developed in calcareous semimentary rock and as alteration products of instrusive rhyolite. Most of clays occur at the contact between the sedimentary rock and the rhyolite, and the alteration zone was observed only in rhyolite body close to the contact. Judging from their occurrences, it is believed that the smectite-rich clays in this area were formed by the hydrothemal alteration. The smectite clays from the area are mainly composed of Ca-montmorillinite, and associated with small quantities of quartz, opal-CT and feldspar. The montmorillinites from this area lower in Fe content, and higher in exchangeable Ca ion, compared to those of bentonite from the Yangnam-Yeongil area.

상관기 진폭 보상에 따른 판별력 조사

황수용,이상이,김남선 서울産業大學校 1996 논문집 Vol.44 No.1

광 JTC는 실시간 상관 시스템에 응용이 가능하다는 장점에 반하여 위상 혹은 진폭성분만을 별도로 처리하기는 어려운 상태에 있었으나, 최근 POC와 POF에 유사한 상관특성을 나타낼수 있는 광 BPEJTC, HPEJTC등이 제안되면서 위상과 진폭이 별도로 처리될 수 있게 되었다. 그러나, 이러한 시스템들은 위상과 진폭이 상관성능에 어떠한 영향을 미치는재 평가하기는 어려운 상태에 있었다. 따라서, 본 논문에서는 진폭이나 위상 성분의 비중을 변동시키며 상관성능을 분석 할 수 있는 것으로 ACMF를 기초로 하는 JTC 시스템인 ACJTC를 수학적 해석을 통해 비교분석하였다. ACJTC는 ACMF의 특성상 위상과 진폭 성분의 비중을 가변시킬수 있으므로 잡음 및 유사표적에 대하여 우수한 상관 판벽력을 나타내게 된다. 이러한 특성을 조사하기 위해 자연게 배경에 다중 표적 영상을 주기적으로 배치하고 컴퓨터 시뮬레이션하였으며, 광 JTC를 통한 실시간 상관 시스템의 구현 가능성을 제시하였다. The optical JTC system has the advantage of being applied to the real-time correlation system, but it has some difficulties that is amplitude and phase signals cannot be separately processed. Recently to solve those problems the BPEJTC and HPEJTC systems having the same characteristics of that of the POC and POF have been proposed. But there is no quantitive analysis how much the amplitude and phase signals are contributed to the correlation outputs respectively. In this paper, a ACJTC system based on the conventional ACMF is discussed through the mathematical analysis. The good correlation discrimination of the system is also analyzed by changing the relative contribution of the phase and amplitude signals for some similar targets. From the successful computer simulation results on the scenario where three same targets are periodically located on the nature background, the possibility of the high performance real-time correlation system based on the optical ACJTC is suggested.
