본 연구는 정상인 집단과 정신분열증 환자집단의 MMPI 반응에서 긍정왜곡에 관한 차이를 알아보기 위한 것으로 329명의 정상군과 110명의 정신분열증 환자군의 MMPI의 결과를 비교하였다. 정상군과 정신분열증 환자군의 긍정왜곡 반응은 통계적으로 유의한 차이를 보이지 않았다. The present study attempted to detect the difference between the normal group and schizophrenic patient group, in faking-good attitude in MMPI responses. Four hundred thirty none subjects were selected and administered the MMPI. The results of 329 normal group were compared to 110 schizophrenic patients. The result reveals the normal group did more faking-good than the schizophrenic group but not significant statistically. On the other hand when L equals or excells 9, K equals or excells 17 and F-K is less than -11, the two groups showed a great difference among the clinical scales, that is, the scale of psychopathic deviates at the significant level P<.05, the scales of psychasthenia, schizophrenia and social introversion at the significant level P<.001. It is recommended that the clinical scales should be used in diagnosing neuropsychiatric diseases.

The objective of this study was to investigated the pretreatment characteristics of sewage sludge by ultrasonic process. Excess sewage sludge was sampled from N sewage treatment plant (STP) in B city. The ultrasonic processor was designed to operate with 28 kHz and 40 kHz,independently. During sonication experiment, sludge samples were stirred by agitator. The acoustic densities were changed 33 to 139 W/L by control of current strength. The sonication time was in the range of 10 min and 40 min. The total chemical oxygen demand (TCOD) and soluble chemical oxygen demand (SCOD) of sludge were analyzed with K2Cr207 Closed Reflux Method. The results showed that sonication with 28 kHz of acoustic frequency is better than sonication of 40 kHz in incensement of SCOD/TCOD ratio. Also, the sludge solubilization rates increased as the sonication time and acoustic density increased. The application of dual frequency sonication for sludge pretreatment can be interest for sewage treatment plants having problems in sludge treatment and disposal.

Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.

Carboxymethyl chitosan의 항균성과 항곰팡이성
선우양일,박현숙,탁연수,최윤정,김광 동아대학교 환경문제연구소 1997 硏究報告 Vol.20 No.1
Chitin was converted to chitosan by deacetylation, and then carboxymethyl chitosan(CM-chitosan)was obtained by carboxymethlation of chitosan. The antibacterial activity was estimated using the miminum inhibitory concentration (MICwt%) assay. MICwt% of Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, candida albican and Staphylococcus aureus were 0.5, 0.5, 0.25, 0.25, 0.75 respectively. CM-chitosan was tested for antifungal antivity which is measured the inhibition of hyphal extension of the fungi. MIC_(50)wt% of CM-chitosan was shown half growth of the experimental over control group. MIC_(50)wt% of Penicillium citrinum, Myrothecium verrucaria and Verticillium albo-atrum were 0.5, and Gliocladium virens was 0.75, respectively. These results showed that CM-chitosan had the high inhibitory effect on the growth of the bacteria and fungi.

Study Design : Two patients who had painful Schmorl's node at thoracic level from acute trauma were adopted and taken operation for its treatment Objectives : To document the effect of operation for the treatment of painful Schmorl's node at thoracic level summary of background data : Schrmorl's nodes are common spinal lesion generally believed to be asymptomatic, but in some cases there were painful symptom by Schmorl's node. This case report is to explain the effect of operative treatment for the painful Schmorl's node. Methods : Two patients were adopted who had traumatic painful Schmorl's node at thoracic level for our case report. They were treated conservative methods at first but it's effect were poor, so they were taken anterior decompression and fusion, and checked back pain symptom. Result : In all two patients, the symptom of back pain by Schmorl's nodes at thoracic level was almost subsided. conclusion : For the treatment of traumatic painful Schmorl's node, most of surgeon says that conservative treatments were treatment of choice, but operative treatments are also benefit to subsidence of back pain by Schmorl's node.

본 저자들은 인위적인 인슐린 투여로 인한 인간성 저혈당증 1예에서 보존적인 치료로 의식기능은 회복하였으나, 현저한 인지능력 저하를 하였기에 문헌고찰과 함께 보고하는 바이다. Factitious hypoglycemia is a covert attempt to lower the blood glucose concentration with insulin or a sulfonylurea agent. This attempt is mainly performed by the patients themselves. In a large series of diabetics who had overdosed on drug, less than 5% had used insulin for suicidal or homicidal purposes. Additionally, 4 of 204 hypoglycemic episodes were due to a suicide attempt with insulin. The onset of insulin action, its peak level, and duration, and the degree of hypoglycemia, are determined by insulin's pharmacokinetics. However, the final outcomes are not associated with the amount of insulin used. The complications related to insulin overdose are cerebral damage and hypokalemia. Other complications include, pulmonary edema attributed to congestive heart failure and hypertensive crisis, as well as respiratory insufficiency. We report this case with a review of the literature.

Taxol, a natural product with significant anti-tumor activity, stabilizes microtubules and arrests cells in the G2/M phase of the cell cycle. It has been reported that taxol has additional effects on the cell such as an increase in tyrosine phosphorylation of proteins and activation of mitogen-activated protein (MAP) kinase. This phosphorylated kinase translocates into the nucleus and phosphorylates its substrate c-jun, c-fos, ATF2, and ATF3. The MAP kinase family is comprised of key regulatory proteins that control the cellular response to both proliferation and stress signals. First examination was cytotoxicity and apoptosis-induced concentration with paclitaxel in HeLa cell. A half-maximal inhibition of cell proliferation ($IC_{50}$) occurred at 13 nM paclitaxel. When DNA fragmentation was analyzed by agarose gel electrophoresis, a nucleosomal ladder became evident 24 h after a taxol (50 nM) addition to the cells. In addition, an apoptotic body was detected by electron microscopy. Taxol-treated cells were arrested at the S phase at 10 nM. Treatment of 50 nM taxol activated the extracellular signal-regulated protein kinase (ERK1), and a fraction of the activated MAP kinases entered the nucleus. It was also discovered that nucleus substrates c-jun was phosphorylated and activated in the cell. The activated ERK1 could subsequently translocate into the nucleus and phosphorylate its substrate c-jun as well. This study suggests that taxol-induced apoptosis might be related with signal transduction via MAP kinases.
