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.

This paper is results of extensive centrifuge model experiments about design factors influencing the bearing capacity and the settlement behaviors of SCP (Sand Compaction Pile). Centrifuge model tests were carried out changing design factors for SCP method such as replacement area ratio (as= 20, 40, 70%), improvement ratio to footing width (W/B = 1, 2, 3), and amount of fines in sand pile (#200 = 5, 10, 15). Therefore, the effects of these design factors on the bearing capacity and the settlement behavior of SCP were investigated and changes of stress concentratio rato due to such an design factors were also investigated. Centrifuge model testing technique for preparing and installing centrifuge model of sand compaction pile, using freezing them, was also developed. As results of centrifuge model tests, more fines in sand compaction pile increases the bearing capacity of SCP. Optimum improvement ratio to footing width was found to be 2. Values of stress concentration ratio was in the ranges of 1.5 - 3.5. The depth of bulging in sand piles was found in the range of 2.0 - 2.5 times of pile diameter.

Background & Purpose: The study for inhibitors of gene products participating in multistep carcinogenetic event of human cancer is important target relevant to chemoprevention or adjuvant therapy of cancer. This study was performed to search basic data for chemoprevention or adjuvant therapy of human non-small cell lung cancer and to evaluate coexpression of each gene product, the relationship between the expression of each gene product and clinicopathologic factor or prognosis. Method: The following formalin-fixed paraffin embedded surgical specimen was immunohistochemically stained by avidin-biotin complex method for C-erbB-2 and COX-2; 55 cases of squamous cell carcinoma and 29 cases of adenocarcinoma of lung. Results: Positive C-erbB-2 and COX-2 expression is more often seen in adenocarcinoma compared with squamous cell carcinoma. Correlation between early and advanced cancer was insignificant. Coexpression of C-erbB-2 and COX-2 expression is more often seen in adenocarcinoma compared with squamous cell carcinoma. Conclusion: These results suggested that degree of C-erbB-2 and COX-2 expression depended upon histologic type of non-small cell lung cancer. However, further studies are required for the determination of significant relationship in coexpression of two gene products and clinicopathologic indices.

The purpose of this study was to investigate how exercise affect the cardiorespiratory function and level of serum lipids in adolescent obesity. The test subjects were twenty obesity men(obesity group) and twenty general men(general group) enrolled at N.S junior high school in March, 1997. The age of subjects were distributed between thirteen and fifteen. The heart rate(HR), VO_2max, systolic blood pressure, and serum lipids were measured before and after the Ergometer exercise for 12 minutes. All data were processed by IBM package SPSS-PC^+ for statistical analysis. The results obtained in this study were summarized as follows; 1. The %fat were 13.9±1.86% in general group and 24.5±1.68% in obesity group. 2. The Heart Rate at resting were 75.4±7.02beats/min in general group and 85.8±5.53beats/min in obesity group. And the HR after twelve minutes ergometer exercise were 163.2±4.52beats/min in general group, 175.5±5.13beats/min in obesity group. 3. The Systolic Blood Pressure at resting were 117.0±7.32mmHg in general group and 121.0±6.41mmHg in obesity group. And the Systolic Blood Pressure after twelve minutes ergometer exercise were 160.3±6.58mmHg in general group, 169.0±8.67mmHg in obesity group. 4. The VO_2max were 45.38±6.22㎖/㎏/min in obesity group. 5. The serum Total-Cholesterol level at resting were 133.3±16.01㎎/㎗ in general group and 179.9±30.82㎎/㎗ in obesity group. And the serum Total-Cholesterol level after twelve minutes ergometer exercise were 136.5±15.04㎎/㎗ in general group and 184.5±33.14㎎/㎗ in obesity group. 6. The serum Triglyceride level at resting were 61.8±11.77㎎/㎗ in general group and 112,3±22.55㎎/㎗ in obesity group. And the serum Triglyceride level after twelve minutes ergometer exercise were 69.7±12.08㎎/㎗ in general group and 120.9±20.09㎎/㎗ in obesity group. 7. The serum HDL-C level at resting were 48.4±4.97㎎/㎗ in general group and 36.9± 4.69㎎/㎗ in obesity group. And the serum HDL-C level after twelve minutes ergometer exercise were 49.2±4.49㎎/㎗ in general group and 38.9±5.79㎎/㎗ in obesity group. 8. The serum FFA level at resting were 565.1±125.09㎎/㎗ in general group and 679.2 ±179.76㎎/㎗ in obesity group. And the serum FFA level after twelve minutes ergometer exercise were 720.1±131.59㎎/㎗ in general group and 882.9±191.57㎎/㎗ in obesity group.

As the use of preservatives in foods has been increased, the misuse and overuse of preservatives are occasionally occurred. As the variety of food has risen, it is necessary to establish the screening method to determine preservatives in various foods. In this study, benzoic acid, sorbic acid, methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, i-propyl p-hydroxybenzoate, n-butyl p-hydroxybenzoate were analyzed by TLC and HPLC. In order to determine the recoveries from food, these preservatives were spiked into foods. As a result, solvent systems of 8:2:0.45:0.05 and 12:2:0.45:0.05 of pentane:acetic acid:chloroform:ethanol were appropriate for TLC analysis of preservatives. All preservatives were well resolved with solvent system of 2% ammonium acetate in 2.5% acetic acid:methanol (90/10~10/90) by HPLC. Direct extraction of preservatives from food proved to be more proper than distillation and extraction method. The recoveries by direct extraction method showed 93.7~104.6% of preservatives studied.

Emissions from aircraft have impacts on the air pollution of airport and the surrounding area. There are methods of emissions calculated as Tier 1, Tier2, Tier 3A and Tier 3B. Thus, this study investigated emissions from aircraft at the Gimhae International Airport using EDMS(Emissions & Dispersion Modeling System) program. Results of estimation from aviation emissions, Tier 3B considering all parts which can occur at the airport has the largest amount emissions. In order to understand the relation between aviation emissions and distribution of ozone concentration over airport area, numerical evaluation were carried out. Although the difference of surface ozone distribution between numerical assessment with and without aviation emissions was little, effects of air pollution at airport area from aviation emissions of NOx and VOCs.
