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.

The dietary effect of water extracts of Liriopis tuber(WELT) in the diabetic SD-rats on the level of blood sugar and serum cholesterol was investigated. The experimental plots divided into normal group(N), diabetic control(DC), 5% WELT-group(WELT-Ⅰ) and 10% WELT-group (WELT-Ⅱ). Each group was fed for 6 weeks, then continuously fed for 1 more week after streptozotocin injection. The loss of the body weight fed for one week after induction of the diabetes was 2.2~6.3% in the WELT-Ⅰ and -Ⅱ groups, but it was 18.6% in the DC-group. There was no significant difference in the feed intakes after diabetes induction between N-group and WELT-group, while it was significantly increased in DC-group. The feed efficiency ratios before diabetes induction were 1.70 in WELT-Ⅰgroup, 1.53~1.59 in the N, DC and WELT-Ⅱ group, while the ratios after diabetes induction were 0.92 in DC-group, 1.51~1.83 in the N, WELT-Ⅰ and -Ⅱ group. While the amounts of water intakes for one week after diabetes induction was 625.4 mL in the DC-group, and it were 364.3~371.1 mL in the WELT-groups showing no significant difference with N-group. The excretion amounts of urine were 431.96 mL in DC-group for one week after diabetes induction, and it was 182~192.84 mL in WELT-groups. The ratios of liver weight against body weight were 2.74% in N-group, 2.93~2.96% in WELT-groups, but it was 4.01% in DC-group. The level of blood glucose in WELT-groups fed for one week after diabetes induction were 136.8~138.6 ㎎/dL showing no significant difference with N-group, but it was 357.8 ㎎/dL in DC-group. The level of serum triacylglycerol and serum total cholesterol were 93.8 and 68.7 ㎎/dL in N-group, 120.1 and 101.6 ㎎/dL in DC-group, 97.4~100.6 and 60.8~67.7 ㎎/dL in WELT-groups, respectively, showing no significant difference between N-group and WELT-groups. HDL-cholesterolltotal cholesterol ratio were 0.63 in N-group, 0.57~0.67 in WELT-groups, which was significantly higher than that of DC-group(p<0.05). Atherogenic index were 0.58 in N-group, 0.49~0.74 in WELT-groups, but it was 1.32 in DC-group. The above results suggest that the WELT diets may have both preventive and curing effects against the diabetes.

This study was to investigate the effect of selenium on hepatic antioxidative defense system and oxidative damage in lead-administered rats. Male Sprague-Dawley rats weighing 140±5g were divided into one normal group(Se, 0 ppm) and three lead groups according to dietary levels of selenium supplementation: Pb0(Se, 0 ppm), PbS(Se, 0.5 ppm), and PbSS(Se, 1.0 ppm). All experimental groups were fed the experimental diet ad libitum for 4 weeks, and lead groups fed one containing 2,000 ppm lead acetate. Liver superoxide dismutase(SOD) activities in Pb0 group increased compared with other experimental groups. Liver gluthathione peroxidase(GSH-px) activities in Pb0 group decreased compared with normal group, but those of PbS and PbSS groups significantly increased compared with Pb0 group. Glutathione S-transferase(GST) activities decreased in Pb0 group and not significantly different from PbS and PbSS groups compared with normal group. Reduced glutathione(GSH) contents and GSH/GSSG of liver in Pb0 group were lower than those of other groups, Liver vitamin E contents in Pb0 group were about 50% of the normal group, but those of PbSS and PbS increased more than Pb0 group. Liver damage in electron microphotography process decreased in RER, showed an increase in lysosome and also an increase in swelling of mitochondria, and ordered as follows: PbSS. PbS, and Pb0. It was concluded that high levels of dietary selenium had protective effects on peroxidative damage of hepatic cell accompanied with increased antioxidative defense system in lead-administered rats.

무주(武周)의 성립 배경과 통치기반

추교순 ( Gyo Soon Chu ) 충북대학교 사학회 2010 忠北史學 Vol.24 No.-

According to previous studies, Empress Wu took part in politics from the era of Emperor Gaozon and reigned supreme as a de facto ruler. Some scholars argue that Empress Wu was involved in politics in the Tang Dynasty for 40 to 50 years. However, it seems that Empress Wu exercised governing power as a de facto ruler for about 20 years from 684 to 704. During the period, Empress Wu`s ruling power was independent of the era of Emperor Gaozon, and it needs to be classified as the era of Empress Wu. At that time, Empress Wu did not participate in politics as the Queen. Empress Wu created her own power base and exercised power as a de facto emperor. According to the study, it has been found that there were several reasons why Empress Wu came into power and established the Wu-Zhou Dynasty. First, when Emperor Gaozon died, he expressed his dying wish asking Empress Wu to make decisions on important state affairs. Emperor Gaozon meant assistingthe next emperor and guarding the Tang Dynasty. However, the new emperor was dethroned by Empress Wu and subjects in two months. Another emperor acceded to the throne, but Empress Wu already held real power to make important decisions on state affairs as Emperor Gaozon said at his last moment of life. Second, Li Jingye`s rebellion in 684 was a strong threat posed against Empress Dowager Wu. It was soon suppressed, and Empress Wu was able to strengthen her power as an independent emperor not as Emperor Gaozon`s wife or Emperor`s mother. After defeating the rebellion, Empress acquired confidence that she could rule the world and furthered her ambition to become the emperor. Third, after suppressing Li Jingye`s rebellion, Empress Wu was able to control subjects, and as she defeated a rebellion by Li Zhen and his son who were the descendants of the Emperor Taizong, she was able to control the Royal family. During 15 years of the Wu-Zhou Dynasty, Empress Wu chose to ascend the throne to rule the world instead of controlling opponents with a high handand by force. As Empress Wu succeeded to the throne, the dynasty was replaced, and it was no customary for a woman to become an emperor. Empress Wu had to overcome male domination in the ancient China and acquired legitimacy at a time of replacing the Li Dynasty with the Wu Dynasty. Empress Wu took advantage of a propitious site to justify the Wu Dynasty and manipulated the public opinion to create a favorable environment where she can naturally succeed to the throne. Although Empress Wu held real power and opened the Wu-Zhou Dynasty, she was also vulnerable to threats posed by opponents. For this reason, she administered justice rigidly and conducted a reign of terror by appointing cruel subjects. The degree of the reign of terror was further strengthened or weakened every time. However, the reign of terror in the Wu-Zhou Dynasty continued for as long as 15 years.

This study is to analyzing needs on sofa of the aged through identifying the demanded trend and examining physical discomfort experienced by whom had used them. The subjects were 103 people aged 60 and over who had visited a welfare center in Seoul. Data were collected by a questionnaire, and analyzed using x² -test and Pearson’s correlation coefficient. As a result of the study, about 43% of subjects were using the sofa for 5 hours or more, and 82% were using sofa to watch TV. For the most important part of the sofa, 70% answered seating comfort, and 48% demanded increasing in height of a backseat whose head could be reclined. As for price, 74% thought that 1 million won or less was appropriate, and about 75%, showed that the period of use of sofa should be less than 15 years. It was perceived beneficial when it relieves the muscular tension on the knee joint, hip joint, and lower back. Subjects mostly complained the firmlessness of the cushion and discomfort of the depth of the floor cushion. On the basis of this study, design of sofa for the aged, the height of the backrest, the seating comfort, the firmness and durability of the cushion, price should be considered.
