朴明鎬 대구보건대학 1988 대구보건대학 論文集 Vol.11 No.-

For the detection of the active cariogenic factors contributing to caries development, some practical methods such as the Snyder test, estimation of salivary flow rate and salivary buffering capacity test were evaluated statistically by comparing DMFT and DMFS indexes. Total 122 children(62 male and 60 female; 64 rural and 58 urban) were selected ramdomly from the 6th grade of the primary school and their salivary cariogenic factors were analysed and evaluated. Among the total 122 children, 78.7% was positive in the snyder test in which the marked, moderate and slight caries activities were 29.5%, 30.3% and 18.9%, respectively. In the Snyder test, 74.45% was positive in urban children while 84.48% was positive in rural children. DMFT and DMFS indexes were markedly lower in negative group than positive group of the Snyder test (P<0.01). The mean and standard deviation of stimulated salivary flow rate was 6.97±2.57 in male and 6.34±2.54 in female but no significant difference was observed in sexuality. The stimulated salivary flow rate of urban children was slightly higher than that of rural but there was no significant difference between them. However, the group that showed below average in the stimulated salivary flow rate was markedly higher in DMFT and DMFS indexes than the group of above average. The mean and standard deviation of stimulated salivary buffering capacity was 7.65±2.19 in male and 6.80±1.67 in female. This difference was significant statistically (P<0.05). Stimulated salivary buffering capacity of urban childen was higher than that of rural. Increases in stimulated salivary flow rate and buffering capacity had reduced the onset of dental caries of 14-year-old permanent tooth.

폴리머 콘크리트 복합체를 이용하여 악천후에도 시인성이 좋고 주위의 경관과 어울리는 자동점멸 표지병을 개발하였다. 아날로그 회로에 비해 설계상의 난해한 점이 있으나 상대적으로 간편한 디지털 회로를 사용하여 자동점멸 회로를 구성하였으며, 작업의 능률을 높이고 개발비를 줄이기 위하여 OrCAD를 사용한 Simulation을 실시후 회로를 구성하였다. 표지병의 시공시와 같은 환경에서의 실험에서는 디지털회로의 작은 전류와 표지병간의 거리, 전선의 저항으로 인하여 클럭 및 클리어 신호에 전압강하와 상승/하강 시간의 증가가 나타났다. 표지병은 전자회로와 함께 설치되어야 하므로 방수성을 고려하여 표지병과 전자회로를 일체형으로 설계하였다. 실제 시공시의 환경에서 시행한 실험에서 나타난 문제점을 검토하였으며, 향후 연구방향에 관하여 고찰하였다. Using polymer concrete composite, the automatic-on/off road marker that is well distinguished in a bad weather condition of rainy or foggy day and is well harmonized with. Digital circuit that is hard to design but simpler than an analog circuit is used in designing the automatic-on/off circuit, and it order to raise the working efficiency and lower the development cost, OrCAD, a simulation tool of electric circuit, was used in simulating the circuit. In an experiment conducted under the circumstance of practical application, voltage drop and raising/lowering time increment in the clock and the clear signals are occurred because of small current of digital circuit and resistance of electrical line. Because that the road marker is assembled with the digital circuit, it is designed as one assembled unit by considering water proof. Some problems occurred in the experiment and the future work are discussed.

In order to examine the effect of testosterone on antinociception and the role of opioid system as an underlying mechanism, thirty-seven adult female mice(Institute of Cancer Research) were randomized to Naloxone(n=18) and Control group(n=19). Testosterone propionate(1mg/kg, ip) with naloxone HCL(2mg/kg, ip) or with normal saline(5ml/kg, ip) was administered on the first and the third experimental days. Nociceptive sensitivity was measured by Tail flick test(TFL, sec) before and after injection on the first and the third experimental days. The same dose of testosterone was injected on the second experimental day. The results were as follows; 1.TFL of control group was significantly increased by testosterone. TFL of control group measured on the first experimental day before and after injection were 5.5±1.1 sec(mean±sd) and 6.3±1.2 sec, respectively, and the change was significant(t=4.06, p=0.001). That measured on the third experimental day before injection was 5.9±1.0, showing a significant increase compared to that of the first experimental day(t=2.37, p=0.029). 2.Testosterone-induced antinociception was blocked by naloxone. In naloxone group, change in TFLs measured before(5.6±0.8) and after(5.3±0.9) injection was not significant on the first experimental day. On the third day, TFL measured before injection(6.6±1.2) was increased significantly than that of the first experimental day(t=2.87, p=0.011), but it decreased to baseline level after injection of naloxone(5.3±1.3; t=4.73, p=0.000). From these results, it is suggested that testosterone has antinociceptive effect, which is mediated by endogenous opioid system.

To evaluate the rehabilitative care needs of the patients with spinal cord injury in this regional area, the complications which were seen in the department of rehabilitation medicine in Chungnam National University Hospital during the 1st year since the opening of the isolated rehabilitation medicine ward in September 1989 were analyzed. The study population was consisted of 25 men and 2 women. Nine cases (33.3%) were in the 20-29 age group and 11 cases (40.8%) were injured by traffic accident, the most common cause of traumatic spinal cord injury in this study. Sixteen cases(59.2%) were paraplegics and eleven cases(40.8%) were quardriplegics. The duration from the onset of injury to admission to the department of rehabilitation medicine ranged from 21 days to 14 years with mean of 18 months. The complications seen in this study were as follows. 1. Urinary tract infections, most common complication, were found in 14 cases (51.6%) followed by decubitus ulcers (44.4%), edema of leg (22.2%), spasticity (18.5%). 2. The most common organism of urinary tract infection was E.coli(43.0%). 3. Among the 22 cases which underwent IVP and VCUG, 2 cases showed hydronephrosis in IVP and 4 cases showed vesicoureteral reflux in VCUG. 4 The most common site of pressure sores was sacrum(53.3%). 5. The mean duration of pressure sore healing with non-surgical treatment was 18 days in Grade II and 42 days in Grade III. With the above results, it is concluded that most frequent complications of patients with spinal cord injury were urinary tract infection and pressure sores, with most of them being occurred before the admission to department of rehabilitation medicine and being treated completely during the stay in the department of rehabilitatiom medicine, and that the comprehensive rehabilitation treatment for the prevention of complications is necessary from the onset of injury.

High quality Ta₂O? dielectric films were deposited by low-pressure metalorganic chemical vapor deposition (LPMO-CVD) from Ta(OC₂H?)? and oxygen. The microstructure and Ta₂O?/SiO₂/Si interfacial properties were investigated by XRD, SIMS, SNMS, RBS, SEM and TEM, XRD analysis showed that the structure of as-deposited thin films was amorphous, but it was crystallized to orthorhombic β-Ta₂O? by after-annealing at temperatures higher than 700˚C. The SiO₂layer at TiO₂/Si interface is strongly dependent on after-annealing conditions and dominates the electrical properties of Ta₂O? thin films on Si.

Objective : Bipolar disorder is a disease with diverse clinical profiles and outcomes. In recent years, it is suggested that if bipolar disorder occurs early in one's life, functional and symptomatic prognoses are poor. The prognoses include severe Symp-toms, frequent psychotic symptoms, comorbidity ofmental illnesses, slow improvement of the symptoms, and high suicide rate. We investigated the clinical characteristics of early onset bipolar inpatients. Method : The subjects of this study were selected from the patients who were discharged after hospitalization between January 1, 2001 and May 31, 2005 and diagnosed with bipolar disorder according to DSM-IV criteria. These patients were examined for the following data ; the type of bipolar disorder, comorbid psychiatric disorders, the age at onset of the illness, the acuteness of the disorder, and the duration of the disorder. The presence of four major clinical psychopathology, rapid cycling, Psychotic symptoms, comorbid psychiatric disorders, and suicide attempt, was also examined. The patients whose onset of the illness was before the age of 19 were classified as the early onset group and after the age of 19 were classified as the late onset group. Data on demographics, family histories, four major clinical psychopathologies and other clinical variables were compared between the early onset group and the late onset group. Results : Of the 53 patients, 19 patients belonged to the early onset group. There was higher incidence ofpsychotic Symp-toms in the early onset group than in the late onset group, and the difference was statistically significant according to the χ² - test (84.2% vs 44.1%, P=0.005). The incidence of comorbid psychiatric disorders was higher in the early onset group than in the late onset group, and the difference was also statistically significant according to the χ²-test (52.6% vs 23.5%, P=0.032).However, there was no statistically significant difFerence between the groups regarding the incidence of rapid cycling and suicide attempt. The result of logistics regression showed correlation of psychotic symptoms (0R=6.756 ; 1.655≤95% CI≤27.580) and comorbid psychiatric disorders (0R=3.611 ; 1.088≤95% CI≤11.984) with the early onset group. Conclusion : Early onset of bipolar disorder is related to the manifestation of psychotic symptoms and frequently accom-panies comorbid psychiatric disorders. The results of this study will help understand the mechanism of the onset of complexbipolar disorder and estimate the prognosis.
