Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

Objectives : Impaired processing of facial information is one of the broad ranges of cognitive deficits seen in patients with Schi-zophrenia. We aimed to elucidate the differences in brain activities involved in the process of facial working memory between schizophrenic patients and healthy comparison subjects. Methods : Twelve patients with schizophrenia were recruited along with twelve demographically matched healthy volunteers as a comparison group. Functional magnetic resonance imaging (fMRI) was used to assess cortical activities during the Perfor-mance of a 2-back working memory paradigm using images of neutral faces as mnemonic content. Rcsults : The patient group performed the tasks with reduced accuracy. Group analysis revealed that the left fusiform gyrus, the right superior frontal gyrus, the bilateral middle frontal gyri/insula, the left middle temporal gyrus, the precuneus, the quadrangular lobules and the vermis of cerebellum showed decreased cortical activities in the patient group. On the other hand, an increased level of activation in the lateral prefrontal cortex and the pahetal lobule was observed from the patient group, all in the right hemisphere. Conulusion : A decreased level of activity in the left fusiform gyrus among the patient group implicates inefficient processing of facial information. An increased level of activation in prefrontal and parietal neural networks from the patient group confirms earlier findings on the impaired working memory of patients with schizophrenia.

This study is carried out to investigate the water quality change trends in Pusan Metropolitan streams. The temperature of the streams are moderate except in winter period and this can be explained by the Korean meterological characteristics. The pH does not vary by the time but some points are a little low. BOD_(5) and COD_(Mn), the index of water contaminants, be shown as characteristic domestic waste water patterns. The nutrient matters, such as total nitrogen and total phosphate, are appeared to be low. The chronic water quality, as BOD_(5) and COD_(Mn), shows that the loading rates in 1998 are smaller than the past(1983, 1992). Some points show a little high loading in autumn, but this needs more investigation to make clear the cause(s).

Mobile nodes in ad hoc mobile networks typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper proposes a solution that allows mobile nodes to access the wired Internet and to roam from base station to base station. And we also develop the efficient method that adapts in Global MANET which can be changed over time. It is observed that we can reduce not only error detection time but also network load, thus increasing the data reception rate in Global MANET Environment.

In the contemporary society, the main purpose of women hall to be changed. The programs should be established and operated to provide an opportunity for social education and welfare for women. Also, it is necessary to provide family-unit programs. Therefore, the purpose of this study is to present an direction for constructional plans for the women hall, which are now under way without much consideration. For this, the author analyzed the current status of women halls and their related offices located in the small and medium sized cities in Kyungi-do area, and then provided a direction for the future plans including the realities of usage and plans of unit space, such as the size, user characteristics, operational status.

Early repolarization is a common electrocardiographic (ECG) feature found in young adults, men and athletes, and has been considered to be a benign feature for the last several decades. But recent studies suggest that early repolarization may be related to idiopathic ventricular fibrillation and sudden cardiac death. We report a young man, 35 years old, who had life threatening ventricular fibrillation and sudden cardiac arrest. He was evaluated for cardiac causes of ventricular fibrillation. There was no explanation other than that his ECG showed an early repolarization pattern so we treated him with implantable cardioverter defibrillator. Thus, we suggest that early repolarization may be related with life threatening ventricular arrhythmia.

A CFD simulation of airflow and temperature filed in a heated room has been described in this paper. The thermal wall jet created by a radiator greatly influences the airflow pattern, temperature distribution. The area close to a heat source has a high risk of air-borne contamination and imposes a harmful effect on occupants in that area. The predicted flow field, temperature results show good agreement with the measured data. As the results were compared with experimental data. the applicability of CFD was satisfactorily verified. Also, the CFD simulation can capture the natural convective flow features. If a CFD simulation is applied ventilation design with a heat source, An effective design will be attained. Further study is required to improve the accuracy of CFD simulation.

Background: Necrotizing enterocolitis is the most common gastrointestinal emergency in the neonates and its course is often fulminating with progressive lethargy. The purpose of this study is to determine the period of NP0(non per os) treatment in the patients with neonatal necrotizing enterocolitis. Matenal and methods: For determining the normal range of CT(Computerized tomography) attenuation coefficients of urine from normal neonates, 60 normal neonates participated in this study. And urine specimens from 16 patients with stage IIB necrotizing enerocolitis were obtained 8-12 hours after the instillation of iohexol enterally. The attenuation coefficients of each urine specimen were determined with CT. Periodic examinations were performed at an interval of two days. As soon as the values of attenuation coefficients reached the normal range, we discontinued NPO treatment. Results: The mean period of NPO treatment of 16 patients with stage IIB necrotizing enterocolitis was 11.1 days. The NPO period of 6 patients were 8 days, two were 10 days, four were 12 days, one was 14 days and three were 16 days. Conclusion: By means of this study, we were able to determine the period of NPO treatment on a case by case basis. The authors think that CT examination of the obtained urine after the instillation of iohexol may be a good method to determine the period of NPO treatment.

Objectives : The purpose of the study was to assess the risk factors assumed to be related to the high frequency hearing loss in the noise-exposed male workers. Methods : 712 occupationally noise-exposed male workers were included in this cross sectional study. The subjects filled out a questionnaire on the history of noise exposure, hearing protection, otologic diseases, tobacco smoking, and were tested on height, weight, hematocrit, serum total cholesterol level, fasting plasma glucose level and arterial blood pressure level. Pure tone audiometry and otoscopy were conducted and the subjects were allocated into two groups according to whether they had 4000 Hz hearing loss or not. Results : The multiple logistic regression analysis showed that military noise exposure, poor wearing status of the hearing protection devices, increased age, long noise exposure duration, mean arterial pressure less than 80mmHg, high fasting plasma sugar are the factors significantly related to high frequency hearing loss (P〈0.05). On the contrary, there was no significant relationship between noise intensity, body mass index, serum total cholesterol level, smelling and high frequency hearing loss. Low hematocrit was shown to be a significant factor with a p-value less than 0.1. Conclusions : High frequency hearing loss in the noise-exposed male workers is related to military noise exposure, use of hearing protection devices, age, noise exposure length, fasting glucose level and mean arterial pressure, in this order. Appropriate use of the hearing protection devices has a great impact on the prevention of the noise-induced hearing loss.
