Citrobacter species is a gram-negative bacilli that can cause opportunistic infections in immunocompromised hosts. Citrobacter braakii refers to the genomospecies 6 of the Citrobacter freundii complex. There are no detailed studies on infections caused by this newly identified specific genetic species in Korea. We herein report a case of a patient with hepatocellular carcinoma who, after undergoing transcatheter arterial chemoembolization, developed biloma which later progressed to C.braakii sepsis and did not respond to treatment. To our knowledge, this is the first reported case in Korea on C. braakii infection resulting in septic shock in a patient with malignancy in Korea.

Culdocentesis is a procedure that checks for abnormal Quid in the space just behind the vagina (cul-de-sac). First, a pelvic examination is done. Then, after exposing the postehor vaginal fonix with a bivalve vaginal speculum the posterior lip of the cervix is grasped with a tenaculum. The cul-de-sac is then entered through the postehor vaginal wall with an 18-20 gauge needle with a syringe inserted. As the cul-de-sac is entered, suction is applied, and the intraperitoneal contents are aspirated. In the recent past, culdocentesis was commonly used in the evaluation of a vahety of common intraperitoneal conditions, principally, the hemorrhage associated with ectopic gestations and ruptured ovarian cysts the presence and/or drainage of purulent associated with pelvic inGammatory disease, and as a screening procedure to facilitate early diagnosis of ovarian neoplasms. Usually 16-18 gauge needle with a syhnge attached was used for culdocentesis. But we have experienced a case of therapeutic culdocentesis with 16 gauge angioneedle in patient of hemoperitoneum. So, report it with a bhef review of literature.

Rail noise and vibration is one of the major problem for the residents living nearby railway tracks. The rail noise may inflict a considerable damage to physiological, spiritual, mental and discomfort to neighboring peoples. Therefore, residents living nearby railway were appeal many troubles. Nevertheless, in our country, adequate guidelines for the rail noise are not yet established because of the lack of basic data and insufficient research works. In this point, this study attempts to surveys the influence of rail noise in urban area using questionnaire. This study also present a basic data in establishing effective plans for rail noise in the future.

This paper presents the design, implementation and operations of the interactive information management system, STI²MS, supporting particular for the system-level testing phase which accounts for up to 50% of the man-months of the total system development phase. The system-level testing process is performed to correspond to the results of the design process. The preparation and analysis of the system-level testing process are jointly executed by the electronic switching system. Therefore, a well-designed support environment which integrates the system-level testing activities and the relevant facilities with an information database is being developed. Thus, we developed the test information management facility, STI²MS, which has the following properties and is possible to run on SUN-3/260(UNIX 4.3BSD) workstation system. ·Interactive man-machine interface ·Information change history management ·Hangul data processing ·Based on Troll/USE relational database management system ·Various output forms generation

Objectives : Diffusion tensor imaging (DTI) is a new technique that can be used to visualize and measure the diffusion of water in brain tissue. It is particularly useful for evaluating white matter abnormalities. In this paper, we investigated the neuropathology of the corpus callosum in patients with schizophrenia through the new methods, diffusion tensor imaging. Methods : Diffuse tensor imaging was performed in 19 schizophrenic patients and 26 healthy controls. One complementary measure, fractional anisotropy (FA), which is considered to be sensitive indices of axonal integrity, was obtained from regions of interest in the five areas of the corpus callosum. Neuropsychological measurement also underwent for measurement of frontal lobe function in two groups. Results : There were no significant differences of FA in the DTI measures for either the schizophrenic patients compared with controls. FA was significantly decreased in women compared with men. Neuropsychological measurements such as Wisconsin card sorting test were correlated with FA of patients with schizophrenia. Conclusion : FA measures revealed no differences between schizophrenia and controls. The findings suggest that the structural integrity of white matter in patient with schizophrenia was not disrupted. The results are discussed in relation to previous studies reporting positive and negative findings. It is concluded that further studies using DTI in larger samples, improved and standardized methods of data acquisition and analysis are needed.

Objectives The authors have evaluated the validity of four currently used screening tools of cognitive function in Korea for dementia and mild cognitive impairment in a community elderly population. Methods We screened 5,085 non-randomly sampled elderly over age 60 in the Gwangju city, Gyeonggi Province. Among those, 927 persons were examined further for evidence of dementia and mild cognitive impairment (MCI). A baseline questionnaire on sociodemographic characteristics and four major screening tests (K-MMSE, MMSE-K, MMSE-KC, and K-HDS) were administered. For the evaluation of validity, we have analyzed the ROC curve and calculated the sensitivity and specificity of each test at its optimal cutoff points. Results ROC analysis of the 3 MMSEs and K-HDS has shown that area under the curve (AUC) was between 0.897 and 0.923 for dementia. Sensitivity and specificity were 0.768 and 0.870, respectively, when the cutoff line was set at 17/18 in K-MMSE. The other two MMSEs had optimal cutoff lines at 16/17 with sensitivity of 0.768 and specificity more than 0.90. K-HDS had its optimal cutoff line at 18/19 with higher sensitivity (0.874) and lower specificity (0.755). Compared with dementia, the four screening tests showed poor validity on MCI, Sensitivity and specificity was in the range of 0.733-0.756 and 0.840-0.855, respectively. Conclusion The validity of the screening tools which are currently being used in Korea to screen for MCI was not significantly different among tests. Because of the difference in the population norm and z-score estimation, use of the common norm is advisable.

ISDN User Part(ISUP) is a defined signalling information control function required a setup/release/supervisor control of circuit-switched calls, and made by monolithic structure(Single level : CCS level 4). A new type of ISDN User Part is hot issues recently. It is possible that it should have minimum impact on the control signalling system and should be modular and structured, against for circuit-switched using new services and broadband ISDN services as a packet mode service and a multimedia call. This paper describes the traditional Monolithic ISUP and the new design concept, the Separated ISUP.

With rapidly industrial development, a railway has become of a main traffic means. But, the rail noise has caused much annoyance for the residents living nearby railway tracks. Therefore, in our country, for established of quite dwelling environment, execute regulation standard of railway noise from January 1, 1997. Efficiency soundproofing measures, however, are very difficult because of the lack of basic data and insufficiency of the existing research. In this point, this study attempts to survey the characteristics of attenuation and propagation of railway noise. And this study intends to get the basic data for establishment of a standard about railway noise.
