This study attempts to evaluate the prognostic value of the APACHE II scoring system in patients of surgical intensive care unit(SICU) and to examine its usefullness in stratifying these patients according to their surgical risk and as a potential aid in making rational and objective treatment decision. The records of 161 patients admitted to the Department of Surgery, Gyeong-Sang National University Hospital between Jan. 1991 and Dec. l995 were reviewed. 1) Of a total of 161 patients, 87 were male, 74 were female, and male to female ratio was 1.71: 1. 2) This group was seen most commonly in the age group of 55-64 which occupied 30.3% of entire group. 3) The distribution of patients according to the etiology were 74 patients(46%) in trauma, 61 patients(37%) iin postop-complication, 26 patients(9%) in others. 4) The distribution of patients according to the APACHE II scores was 9 to 29 point in adm. Day and the most patients was located between 10 and 14 of 62 patient(39%). 5) The length of hospitalization was 9 days in survived patients and 8 days in non-survived patients. The length of hospitalization of 77% of patients in this study was below 10 days. 6) The death rate was 45.45%(73 patient), this patients according to APACHE II scores was 13 to 29, median 19.2 in adm. Day, the most patients was located 20 to 24(20%). Non of the survived patients had the APACHE II score of above 20 points, but all recovered patients were below 13 points. 7) The median APACHE II score in survived patients was 10.52 point at adm. Day and 6.55 point at 5 days after admission. And non-survived patients was 20.25 point at adm. Day and 30.48 point 5 days after admission(p$lt;0.001). 8) Among the patients with low APACHE II score (below 14 points), there was no mortality. But, there was mortality with APACHE II score of above l5 points. We conclude that APACHE II scoring system is useful in measuring the severity of acute disease and predicting the outcome.

In this thesis, a RFID baseband system is implemented based on the international standard ISO/IEC 18000-6 Type-B using FPGA, and also anti-collision algorithm is implemented to improve the system performance. We compares the performance of the proposed anti-collision algorithm with that binary tree algorithm and bit-by-bit algorithm, and also validated analytic results using OPNET simulation. The convolutional encoding, viterbi decoding and spread spectrum is also implemented to improve the system performance

To investigate a horizontal windrose and the mixing height in Masan coastal area, a local atmospheric flow and the concentration of air pollutants were analyzed by abserved data from AWS, airsonde and air sampler. The land-sea breeze model and the ISCST2 model of U. S. EPA(Environmental Protection Agency) were used to predict the concentration of air pollutants such as SO2 and TSP. As a result, during spring the principal wind direction in the Masan region is mainly represented by windrose of the WNW and NW, which can be induced by land breeze and the SE and SSW of sea breeze even if weak wind speed. The mixing height during the measurement was marked with the range from 400 m(0900 LST) to 1450 m(1500 LST), and the height of an inverse layer was presented as the range from 30 m(2100 LST) to 150 m(0300 LST). It is very important to cosider the local wind field for the accurate diffusion and movement of air pollutants in coastal urban area. The atmospheric flow was simulated by the two-dimensional local wind model upon considering the orographic characteristics such as land-sea contrast, mountain valley and urban building. The result of air quality simulated by ISCST2 support that the dispersion pattern of the pollutants in that area was followed as local circulation system in coastal urban area.

Bone fractures are most often seen in racetrack horses because of the high level of intensity in racing. These issues are the main cause of decreased performance in racehorses. Mesenchymal stem cells (MSCs) have been explored to improve intra-articular therapy in racehorses. MSCs are essential for the repair and regeneration of damaged tissues. In this study, the effect of intra-articular injection of MSCs in racehorses was investigated. Before accessing the MSC therapy, synovial fluids were obtained from the fracture site of racehorses, and adipose tissue was collected for MSC isolation. Using the MSC specific marker, adipose tissue-derived MSCs were identified. The racehorses received intra-articular injection of autologous MSCs (or allogeneic) (3 × 107 cells/3 mL). After 1 or 2 weeks, synovial fluids were collected from racehorses. To test the effect of MSC injection using ELISA, we analyzed inflammatory factors from the untreated samples compared to MSC-treated samples of racehorses. The level of pro-inflammatory factors (interleukin-1β and prostaglandin E2) was significantly decreased in synovial fluids of MSC-injected racehorses, compared to before accessing the MSC therapy, whereas, the level of anti-inflammatory factor (interleukin-10) was higher than prior to accessing the MSC therapy. Further studies are needed to investigate the anti-inflammatory mechanism of MSC in racehorses.

Purpose: Endoscopic submucosal dissection (ESD) in early gastric cancer causes an artificial gastric ulcer and local inflammation that has a negative intraprocedural impact on additional laparoscopic gastrectomy in patients with noncurative ESD. In this study, we analyzed the effect of ESD on short-term surgical outcomes and evaluated the risk factors. Materials and Methods: From January 2003 to January 2013, 1,704 patients of the National Cancer Center underwent laparoscopic gastrectomy with lymph node dissection because of preoperative stage Ia or Ib gastric cancer. They were divided into 2 groups: (1) with preoperative ESD or (2) without preoperative ESD. Clinicopathologic factors and short-term surgical outcomes were retrospectively evaluated along with risk factors such as preoperative ESD. Results: Several characteristics differed between patients who underwent ESD-surgery (n=199) or surgery alone (n=1,505). The mean interval from the ESD procedure to the operation was 43.03 days. Estimated blood loss, open conversion rate, mean operation time, and length of hospital stay were not different between the 2 groups. Postoperative complications occurred in 23 patients (11.56%) in the ESD-surgery group and in 189 patients (12.56%) in the surgery-only group, and 3 deaths occurred among patients with complications (1 patient [ESD-surgery group] vs. 2 patients [surgery-only group]; P=0.688). A history of ESD was not significantly associated with postoperative complications (P=0.688). Multivariate analysis showed that male sex (P=0.008) and laparoscopic total or proximal gastrectomy (P=0.000) were independently associated with postoperative complications. Conclusions: ESD did not affect short-term surgical outcomes during and after an additional laparoscopic gastrectomy.

We investigated a total of 335 samples of Korean native mushroom extracts as part of our lipoxygenase (LOX) inhibitor screening program. Among the mushroom-methanolic extracts we investigated, 35 exhibited an inhibitory activity greater than 30% against LOX at a concentration of 100 ${\mu}g/mL$. Especially, Collybia maculata, Tylopilus neofelleus, Strobilomyces confusus, Phellinus gilvus, P. linteus, P. baumii, and Inonotus mikadoi exhibited relatively potent LOX inhibitory activities of 73.3%, 51.6%, 52.4%, 66.7%, 59.5%, 100.0%, and 85.2%, respectively. Bioassay-guided fractionation led to the isolation of inoscavin A from the methanolic extract of P. baumii, which showed the most potent activity and was identified by spectroscopic methods. Specifically, inoscavin A exhibited potent LOX inhibitory activity with an $IC_{50}$ value of $6.8{\mu}M$.
