Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.

In order to raise the accuracy of meteorological data, several numerical experiments about the usefulness of data assimilation to prediction of air pollution was carried out. Used data for data assimilation are surface meteorological components observed by Automatical Weather System with high spatial density. The usage of surface data assimilation gives changes of temperature and wind fields and the change caused by the influence of land-use on meterological simulation is more sensitive at night than noon. The data quality in assimilation is also one of the important factors to predict the meteorological field precisely and through the static IOA (Index of Agreement), simulated meteorological components with selected limited surface data assimilation are agree well with observations

Background: High-sensitivity C-reactive protein (hsCRP), the classic acute-phase reactant, is an extremely sensitive systemic marker of inflammation. A variety of factors seems to influence hsCRP levels. The aim of this study was to elucidate the gender differences in the association between hsCRP and features of the metabolic syndrome (MS) among Korean. Methods: The study population included 1,283 men and 3,265 women aged 40 years and over who were enrolled in Korean Health Examinee Cohort. They were examined in 10 General hospitals from November 2004 to September 2005. The height, weight, waist circumference, and systolic and diastolic blood pressure of the subjects were examined and on concentrations of fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, and hsCRP in peripheral venous blood were measured. Results: In both sexes, there were significant positive correlations between age, smoking, body mass index, waist circumference, systolic and diastolic blood pressure, triglyceride, and fasting glucose and hsCRP, whereas significant negative correlations were present between drinking, and HDL cholesterol and hsCRP. Mean concentrations of hsCRP in men with 0, 1, 2, 3, and ≥4 components of MS were 0.13, 0.16, 0.18, 0.20, and 0.22 mg/L, respectively. The respective mean concentrations of hsCRP for women were 0.08, 0.09, 0.12, 0.14 and 0.14 mg/L. Results of stratified analyses by the number of components of the metabolic syndrome of 0, 1, 2, 3, and ≥4 revealed that an increase in hsCRP concentrations was greater in men than women with an increased number of components of the MS. Conclusion: There was a difference in concentrations of hsCRP between men and women, and especially an increase in hsCRP concentrations associated with risk factor-clusteringof MS was more prnounced in men.

The deterioration behavior by freezing and thawing of concrete has been studied in this paper. The deterioration mechanism has also been investigated by the experimental tests of freezing and thawing of the concrete. The restrict strain due to the difference between inside and utside temperature of concrete was measured by the strain gauge. And it is considered that the deterioration of freezing and thawing is advanced by expansion strain due to the freezing of capillary water and the restrict strain. According to the results of the test, it showed that the durability of concrete was increased by the air entrained admixture and the expanded poly-styrene.

This paper is investigated on the study of uniformity improvement and electrical characteristics for the 1×128 diode array used Hg^0.7Cd^0.3Te. The electrical characteristics were measured for the device manufactured by several different annealing processes and temperatures being discrepant from existing method of annealing processes and temperatures. The results of uniformity were improved from 60∼80[%], the rate of existing uniformity, to 99[%]. The results obtained from analyzing and examining the characteristics of current-voltage(I-V) and capacitance-voltage(C-V) are following. First, the reverse current show 6[㎁] or so. It is seemed to be resulted from the decrease of direct tunneling and trap tunneling of the device. Second, when the input bias voltage is zero, the maximum value of reverse resistance show 12[GΩ], and the mean value of reverse resistance show 5[GΩ]. Third, it is shown that the voltage of the maximum value of resistance is shifted 0.1[V] to the reverse direction.
