  • For the effective classification of complex subjects, a library classification scheme should adopt multiple division principles (or facets). Each of the multiple principles adopted for the division of complex subjects is sequentially applied at each stage of division. The order of application of these multiple principles during the process of division of complex subjects is called citation order. In order for a classification scheme to be consistent and logical, the citation order of division principles applied to classify complex subjects should be concrete and consistent. Especially, in case of enumerative classification system, decisions on citation order to represent complex subjects significantly affect the structure and organization of the classification system. There are basic principles and theoretical canons of the classification theory on the citation order and its application, but they cannot be applied solidly in the process of classification system development for practical reasons. Therefore, this paper first reviews previous works on classification theories regarding citation order, then explores the conditions and circumstances for the application of citation order.

  • As the instruments as well as techniques for hip arthroscopy have developed, the interests and understandings of acetabular labral tear have also increased. As a consequence, the diagnosis itself was increased. However, it is still difficult to be diagnosed accurately in an ordinary clinic. In this brief review, the clinical and radiological characteristics and diagnostic implications of acetabular labral lesions were described to help the surgeon to make a right decision.

  • Experiments were conducted to investigate the effect of topping from mulberry graftages on the their size. Topping season was examined at 10 days intervals from July 15 to August 5 1986 and 1987 on the paddy and upland, respectively. The results were : 1. Topping increased the passed rate of graftages 3.0-15.9%, compared with the control. 2. Optimum season of topping fell around July 15. 3. Topping showed no difference to branch length, survival rate and shoot length in the next year. 4. There was no difference between paddy and upland nursery garden in the passed rate.

  • 수문학적인 물의 순환은 여러 기상인자들과 영향을 주고 받으며 복합적으로 발생하는 자연현상이다. 이에 본 연구에서는 강우패턴에 의한 낙동강 본류 주요지점을 비교 분석하여 유출특성을 파악하였다. 또한 년간 강우량 변화에 따른 유출률 비교를 실시하였다. 선정된 지점은 연속적인 수위-유량관계곡선식이 개발되어 안정적인 시계열자료를 산출할 수 있는 지점으로 낙동강권역의 유역특성을 대표할 수 있는 진동 지점과 도시하천의 특성을 나타내는 금호강유역에 위치한 동촌 지점 및 남강댐 하류에 위치하여 댐방류량에 의한 하천유지유량이 발생하는 정암 지점을 선정하여 유출률분석을 실시하였다. 세 지점의 2008년 순유출률은 30% 내외의 유출률을 나타내고 있으며 주요 호우사상이 집중된 3/4분기의 경우 2007년과 비교하여 약 50% 가량의 작은 유출을 보이고 있다. 특히, 순유출량에 대한 순손실유량은 저 평수기로 대표되는 1, 2, 4분기에서 2007년에 비해 크게 높아지는 결과가 나타나는데 이는 저 평수기 토양 침투 및 증발에 의한 자연적인 손실과 가용하천유량이 적어짐에 따른 취수량의 유출량에 대한 양적 비율의 증가가 원인으로 파악할 수 있다. 2008년 낙동강권역의 순유출률은 2007년에 비해 낮아지는 결과를 나타내며 그 결과, 2008년 낙동강권역의 순유출률은 약 20%~40%의 순유출률을 나타내고 있다.

  • With the developement of non-invasive surgical techeniques, coronary artery bypass graft without cardiopulmonary bypass has become popular. We compared the preoperative risk factors and in-hospital outcomes of patients having off-pump CABG with these having on-pump CABG. Material and Method: From January 2001 to June 2003, 87 patients underwent CABG. Thirty-sin patients underwent on-pump CABG, fifty-one patients under-went off-pump CABG. Preoperative risk factors, extent of coronary disease, operative time, postoperative endotracheal intubation time, duration of ICU stay & hospital stay, the amount of bleeding and postoperative levels of cardiac enzymes were compared in both groups, Result: The were no differences in their sex ratios, ages, preoperative risk factors, preoperative Ml, Canadian classes, extent of coronary artery diseases and, echocardio-graphic ejection fraction between Off-pump CABG and On-pump CABG groups. Off-pump CABG group had significantly lower mean operative time (270$\pm$79.3 min vs 372$\pm$142.2 min, p<0.001), mean ventilation time (17.1$\pm$13.4 hr vs 24.3$\pm$17.8 hr) and CK-MB level (8,9$\pm$18.7 IU/L vs 25.7$\pm$8.4 IU/L) than on-pump CABG groups, On-pump CABG group had more distal grafts (2.2$\pm$0.5 vs 1.7$\pm$0.71 than Off-pump CABG groups did. There were no differences in their postoperative complications and outcomes including amount of postoperative bleeding for 24 hrs, reoperation for bleeding control, mean in-hospital days, postoperative infection, renal failure and neurologic complications between Off-pump CABG and On-pump CABG groups. Conclusion: This study showed that patients who underwent Off-pump CABG had less operation time & intubation time and lower CK-MB level; however, they also have less distal graft. Even though CABG without CPB provided satisfactory results, more clinical experience & longer follow-up is required.

  • This study was conducted to investigate the effects of powdered young barley leaf and its water extract on body weight and lipid metabolism in high-fat fed mice. Male mice were divided into normal group, high-fat (HF) group, high-fat group supplemented with powdered young barley leaf (HF-YBL) and high-fat group supplemented with water extract of the powdered young barley leaf (HF-WYBL). The powdered young barley leaf or its water extract was added to a standard diet based on 1% dried young barley leaf (1 g YBL/100 diet and 0.28 g WYBL/100 g diet) for 8 weeks. Supplementation of YBL and WYBL significantly reduced body weight and epididymal adipose tissue weight in high-fat fed mice. Food intake and daily energy intake were significantly lower in the YBL group than in the HF group. After 8 weeks, plasma triglyceride and cholesterol concentrations were significantly higher in the HF group than in the Normal group; however, both YBL and WYBL significantly lowered those of the high-fat fed mice. The ratio of HDL-cholesterol/total cholesterol of the YBL and WYBL groups were significantly elevated compared to that of HF group. Both YBL and WYBL significantly increased fecal excretion of triglyceride in high-fat fed mice, whereas they did not affect fecal cholesterol concentration. The triglyceride levels of liver, adipose tissue and heart were significantly lower in the YBL and WYBL groups than in the HF group. Supplementation of WYBL also lowered the kidney triglyceride and heart cholesterol concentrations compared to those of HF group. Hepatic lipid regulating enzyme activities, fatty acid synthase, HMG-CoA reductase and acyl-coenzyme A: cholesterol acyltransferase, were significantly lower in the YBL and WYBL groups than in the HF group. Accordingly, these results suggest that YBL and WYBL improve plasma and organ lipid levels partly by increasing fecal lipid excretion and inhibiting fatty acid and cholesterol biosynthesis in the liver.

  • This study was performed for the comparison of the general components, minerals, amino acids, organic acids, free sugars, ascorbic acid, polyphenol content and DPPH free radical scavenging activity of steamed-treated reed (sprout and root) to those of raw reed. Moisture content of sprout and root of reed after steaming treatment decreased from 81.28% and 81.64% to 70.18% and 65.50%, respectively. Crude ash content was the highest in raw sprout and steam-treated root. Crude lipid content of raw sprout and root were almost similar. In addition, crude lipid content of steam-treated sprout was greater than that of root. Nitrogen free extract content of root was 2 times as high as that of sprout. Total free sugar contents of raw sprout and root increased from 1,311.39 mg% and 4,130.98 mg% to 1,157.79 mg% and 3,750.90 mg%, respectively, after steam treatment. Furthermore, the organic acid contents of sprout and root of reed after steam treatment were less than those of raw sprout and root. Calcium and potassium contents were the highest among others in both steam-treated and raw reed. Amino acid content of sprout was higher than that of root in both before and after steam treatment. Among the amino acids, serine content was the best presented in both before and after steam treated reed. Vitamin C content of steam-treated sprout and root of reed decreased from 61.74 mg% and 6.57 mg% to 4.54 mg% and 80.79 mg%, respectively. Total polyphenol content of sprout was greater than that of root in raw and steam-treated reed. DPPH free radical scavenging activity of ethanol extraction of root was greater than those of other extracts of root.
