This study outlines measures related to fiscal policies aimed at responding to the financial crisis according to the timing of commencement and then examines impacts of expansionary fiscal policies on macro variables so as to extract policy implications. The size of expansionary fiscal policy to respond to the financial crisis is found to total 59.8 trillion won (6.1% of GDP in 2007), among which a total of 30.5 trillion won was the increased fiscal expenditure made by the 2008 supplementary budget, the 2009 revised budget and the 2009 supplementary budget. In addition, tax reductions are found to be a total of 29.3 trillion won, mainly driven by the tax reforms in 2008 and 2009. Examining dynamic changes in macro variables caused by the temporary increase in fiscal expenditure and the tax reductions reveals that the increase effect of the real GDP growth rate brought by a temporary rise in fiscal expenditure excluding tax reduction effects turned out to be 1.1%p in 2009 and 0.3%p in 2010, compared to the period without the increase in fiscal expenditure. Meanwhile, when taking into account the effect of expansionary fiscal policies including tax reduction effects, the increase effect of real GDP turns out to be much higher. In the case of 2009, the real GDP rose additionally by 1.9%p, in which 1.1%p by the increase in fiscal expenditure and 0.8%p by tax reduction. Based on these results, the expansionary fiscal policy conducted during the financial crisis since the second half of 2008 can be seen to have played a significant role in helping the Korean economy post a higher-than-anticipated recovery pace from the economic slowdown triggered by the crisis.

The purpose of present study was to compare the sedative effect of intranasal and oral midazolam treatment. The study was conducted on twenty eight child patients who required at least two visits. All the patients showed a good physical status (ASA-I). The patient was randomly assigned to receive midazolam either intranasal (Group I, 0.25 mg/kg) or oral (Group II, 0.5mg/kg) route at each visit. Treatment procedure was divided into six stages. In each stage, sleep score, crying score, movement score and overall behavior score were evaluated. The overall results can be summarized as follows: 1. Through all treatment procedures, no significant difference was observed between Group I and Group II in terms of sleep, crying, movement and overall behavior index. 2. In a questionnaire to the parents, 67.8% of parents answered that the child suffered at intranasal administration, while only 17.7% of parents responded the same way at oral administration. 3. In a questionnaire regarding patients' behavior at home after midazolam treatment, 'Similar to normal behavior' was 78.6% in Group I and 57.1% in Group II, indicating that intranasal treatment of midazolam may be more effective for the recovery.

The aim of this study was to evaluate prospectively the impact of the red ginseng extract on circulating interleukin (IL) 2 and 10 in advanced gastric cancer during chemotherapy after operative treatment. Analysis of circulating IL-2 and 10 was performed in 50 patients with advanced gastric adenocarcinoma who underwent a curative surgery or with an unresectable gastric adenocarcinoma by using ELISA and monoclonal antibodies at preoperative day 1, postoperative months 1, and 3. Twenty-five patients as the control group, twenty-six patients as the non-ginseng (NG) group, and twenty-four patients as the ginseng (G) group were eligible in this study. All plasma IL-2 of the NG and G groups was significantly lower an that of the control group on preoperative 1 day. These values of the G group were more increase than these of the NG group during the postoperative chemotherapy. The mean value of serum IL-10 of the control group (0.608pg/ml) was significantly lower than that of the advanced gastric cancer patients including the NG (12.015 pg/ml) and G group (9.409 pg/ml) (p＜0.001). These values of the G group were reduced progressively during the postoperative chemotherapy. The mesh value of the G group were only close to that of the control group on postoperative months 3 (p=0.003). The number of patients who were enrolled in this study was relatively small to fully evaluate the immunologic effects of the red ginseng extract on circulating IL-2 and 10. Despite this limitation, these results suggest that the post-operative intake of the red ginseng extract have potential to improve earlier anti-cancer immunity with recovering IL-2 and reducing IL-10 from the depressed IL-2 and elevated IL-10 by gastric cancer during the postoperative chemotherapy. This study will be based on the future study to evaluate the anti-immunity of the red ginseng extract.

Due to its less invasive nature and superior visual field, video-assisted thoracescopic excision of mediastinal mass is thought to be comparable to open thoracotomy. Material and Method : From January 1995 to August 2001, the medical records of 38 patients who underwent video-assisted thoracoscopic excision of mediastinal mass was retrospectively analyzed. The outcome of these patients were compared with 5 patients who converted to thoracotomy Result: Male to female ratio was 13(34.2%) : 25(65.8%), and mean age was 39.2$\pm$35.4 years. Regarding the pathology, there were 8 neurilemmomas(21.1%), 6 thymic cysts (15.8%), 5 teratomas(13.2%), 5 ganglioneuromas(13.2%), 4 bronchogenic cysts(10.5%), 3 pericardial cysts(7.9%), 3 thymomas(7.9%), and 2 lymphangiomas(5.3%). The mean operation time was 110.6$\pm$7.0 minutes, mean postoperative tube stay was 4.2$\pm$0.4 days, mean postoperative hospital stay was 5.2$\pm$0.4 days, and mean number of injection of analgesics was 1.9$\pm$0.4 times. Although the mean values for the above indices were less than those of the thoracotomy conversion cases, they were statistically insignificant. Postoperative complications of videoassisted thoracoscopic excision included chylothorax, prolonged air leakage, and unilateral phrenic nerve palsy, all of which recovered before patient discharge. There was, however, permanent unilateral ptosis in one patient. Conclusion : As video-assisted thoracoscopic excision of mediastinal mass is safe, less painful, conducive to earlier recovery and cosmetically more appealing, a more active application of this technique is recommeded.

This study was performed to investigate the effect of pork on the cadmium detoxification in rats. Ninety male Sprague-Dawley strains were divided into five stoups based on cadmium treatment(0, 25, 50, 100, 250 ppm) and cadmium intoxication was observed for 8 weeks. During following 8 weeks, casein was replaced by Pork and the effect of pork was compared with casein. During intoxicating, the growth mte was lessened. Feed efficiency ratio was significantly low, as cadmium intake was high Discontinuing cadmium feeding, the body weights were relieve4 Pork-fed groups seemed to have higher body weight than casein-fed groups. During intoxication, hemoglobin and hematocrit were dependent upon cadmium intake. However, they became normal at detocification stage. Cadmium accumulation of the pour-fed group was lower than that of casein. Especially, the factors which affected the cadmium content in kidney were Cd(p<0.001) and $Cd^*pork(p<0.001)$. Metallothionein(MT) was increased with cadmium, and MT was not likely to be affected by pork. This study may provide scientific background of pork for detoxification from heavy metals such as cadmium.

Background: Recent advance in video technology, endoscopic equipments, and surgical techniques have expanded the use of thoracoscopy from diagnosis of the pleural diseases to treatment of the various intrathoracic diseases. Video Assisted Thoracoscopic Surgery(VATS) is a pretty new and fascinating thoracic surgical modality, and so we present our early VATS resuls. Methods: Using Video Thoracoscopic techniques in 30 patients for 10 months from July 1992 to April 1993, we had performed a variety of procedures. These incuded (1) bleb resections in 18 patients (19 cases), (2) mediastinal tumor excision in 4, (3) lung biopsies for parenchymal pulmonary disease in 3, (4) pleural biopasies in 3, (5) pleural tumor excision in 1, (6) and pleuropericardial window in 1. Results: There were no mortality associated with the procedures. We had minor 8 complications; prolonged air leak in 3 patients, prolonged serous drainage in 2, recurrence of pneumothorax in 1, Honer's syndrome in 1, and hoarseness in 1 patient. None of the 30 patients had reverted to the conventional full thoracotomies. Mean postoperative hospital stay of non-complicated pneumothoraces was about 5 days, which was a little shorter than conventional thoracotomy group. Conclusion: Though we had somewhat higher postoperative complication rate due to lack of experiences in the begining, we were able to convince that VATS had benifical value for patients; lesser postoperative pain, shorter hospitalization, quicker recovery time, and cosmetically superior scar. The role of VATS can be expanded to the diagnosis and treatment of various thoracic diseases, even to the cardiovascular diseases, with satisfactory outcome and less postoperative morbidity.

In this study, the anti-inflammatory effects of Lespedeza cuneata extract on macrophages and wound-healing in wound-induced animal experiments were investigated. In an anti-inflammatory test, 0.1 mg/mL of Lespedeza cuneata extract did not affect growth of RAW 264.7 cells, and Lespedeza cuneata extract suppressed nitric oxide (NO) generation from inflammation-induced macrophages in a concentration-dependent manner. Wounds on the skin of rats were treated with vehicle containing Lespedeza cuneata extract (SSP), vehicle (SCO), and commercial ointment (CCO). The wound and scar sizes in the SSP group were significantly reduced in comparison to the SCO and CCO groups (P<0.05). The epidermis and dermis of the SSP group also recovered faster than the SCO group based on Masson's trichrome staining. The gene expression levels of vascular endothelial growth factor (VEGF) decreased and transforming growth factor-beta 1 (TGF-${\beta}1$) increased in wound tissue from the SSP group compared to that from the SCO group. These results show that Lespedeza cuneata extract accelerates wound-healing through anti-inflammatory activity and induction of collagen regeneration as well as reduces the scar area surrounding wounds. Accordingly, Lespedeza cuneata extract could be useful as a cosmeceutical in the cosmetic industry.

Preterm infants with oligohydramnios after preterm premature rupture of membranes can present with severe respiratory distress immediately after birth, and the most common cause is pulmonary hypoplasia. Unlike infants with pulmonary hypoplasia, some cases have shown dramatic improvement with aggressive ventilatory support during the initial 1-2 days of distress: those patients have been defined as having dry lung syndrome. It is assumed that oligohydramnios leads to functional pulmonary hypoplasia by compression of the fetal lungs: some of the improvement in dry lung syndrome may thus have resulted from inflation of compressed lung tissue and increase of lung compliance. We report two incidences of dry lung syndrome that were treated successfully with high inflation pressure and inhaled nitric oxide (NO): these are the first dry lung syndrome cases to be reported in Korean infants.

With the rapid industrialization and economical development, the electricity demands of the industrial facilities and densely populated large cities are continuing to increase in Korea. The increase in the power consumption requires the extension of power facilities, but it is difficult to secure spaces for equipment installation in the limited space of urban areas. In addition, the 154 kV or 345 kV transmission systems in Korea has a short transmission distance, and are connected to one another in network structures that ensure the high reliability and stability of power supply. This structure reduces the impedance during the fault in power system, and increases the magnitude of in the short circuit fault current. The superconducting fault current limiter (SFCL) was devised to effectively address these existing problems. The SFCL is a new-concept eco-friendly protective device that ensures fast operation and recovery time for the fault current and does not need additional fault detection devices. Therefore, many studies are being conducted around the world. In this paper, based on the wiring method the initial fault current characteristics, current limiting characteristics, according to the incident angle and the change in inductance current limiting characteristics were analyzed in a multifaceted methods.

Nonvolatile memory technology is evolving continuously and commercial products such as FeRAM and PRAM are now challenging their markets. As NVRAM has properties of both memory and storage, it can store persistent data objects while allowing fast and random access. To utilize NVRAM for general purpose storing of frequently updated data across power disruptions, some essential features of the file system including naming, recovery, and space management are required while exploiting memory-like properties of NVRAM. Conventional file systems, including even recently developed NVRAM file systems, show very low space efficiency wasting more than 50% of the total space in some cases. To efficiently utilize the relatively expensive NVRAM, we design and implement a new extent-based space-thrifty file system, which we call NEBFS (NVRAM Extent-Based File System). We analyze and compare the space utilization of conventional file systems with NEBFS and validate the results with experimental results observed from running the file system implementations on a system with actual NVRAM installed as well as on systems emulating NVRAM. We show that NEBFS has high space efficiency compared to conventional file systems.
