Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Cutting experiment was conducted to develop a mass propagation method for Spiraea prunifolia var. simpliciflora Nakai. The optimum season for hardwood cutting was between December and early April, but cutting could be done year-round by using rhizome. NAA treatment (100 ppm) was the most effective as rooting promoter. IBA and IAA were also found to be effective. The effect of sand, red clay, loam, silty loam and vermiculite had little differences in rooting especially when cuttings were done earlier than April 5.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

This paper sought to find out the policy measures through case analysis of Kukkiwon - mecca of taekwondo people - becoming corporation with special status as part of measures for promotion of taekwondo, the country’s traditional martial arts. For this, the study conducted analysis of general policy formation process as well as specific policy formation process in Kukkiwon – MOCST (the Ministry of Culture, Sports and Tourism) situation in an effort to generalize logic of such policies. This study is an attempt to recognize and understand conflict between Kukkiwon and MOCST as one among Kukkiwon, the government and taekwondo organizations, and sought to conduct detailed and in-depth analysis in the aspect of policy beyond normal prescriptive discussion - just remaining in the normative level for the present. For this purpose, this study limited its scope to Eom Un-kyu, Lee Seung-wan, legal corporation Kang Won-sik (2008.6.26 - 2010.6.11) and adopted case study as its methodology for its analysis. Case study, which is an empirical research method using multilateral sources of data for its analysis, can be a useful means for researchers to derive results to identify unique characteristics of social objects as their research target. So, this method was considered as an appropriate one for this study. And the study drew following conclusions in the process of Kukkiwon becoming of corporation with special status First, policy formation process was made through complicated process rather than unilinear one. Second, formation structure of legal corporation was based on friendly relations between MOCST, incorporated foundations and legal corporations of Kukkiwon, and its policy was designed and implemented accordingly. Third, there was increase of influences of taekwondo leaders in the process of policy formation process. Through these findings, the study could confirm that policy was the outcome of important political interactions by means of adjustment and negotiations among policy makers, rather than a reasonable decision. Taking this into account, the study suggested proper allocation between each ministry and department as well as systemization in the process of policy-making of taekwondo.

Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.

본 연구는 21품종의 장미꽃에 대한 식품 및 화장품 원료로 사용 가능성을 살펴보기 위해 페놀성 화합물과 항산화 활성을 평가하였다. 총 폴리페놀, 총 플라보노이드 및 타닌 함량은 러버샤이 품종에서 각각 379.70 mg GAE/extract g, 50.10 mg CE/extract g 및 339.44 mg TAE/extract g으로 높게 나타났으며, 칠백리 품종에서 각각 107.25 mg GAE/extract g, 9.46 mg CE/extract g 및 36.31 mg TAE/extract g으로 낮았다. 페놀산 함량은 총 폴리페놀 함량과 유사한 결과를 보였으며, 러버샤이 품종에서 27.40 mg/extract g으로 높았다. 안토시아닌은 대부분 cyanidin-3,5-diglucoside로 확인되었으며 총 안토시아닌 함량은 유니나 품종에서 8.80 mg/extract g으로 가장 높았다. ABTS 및 DPPH 라디칼 소거 활성은 각각 428.10 및 419.59 mg AAE/extract g로 러버샤이 품종에서 가장 높았으며, 항산화 활성과 페놀 화합물의 함량과 높은 양의 상관관계를 보였다. 이러한 결과는 러버샤이와 같은 항산화 활성이 뛰어난 품종들이 관상 목적뿐만 아니라 높은 기능성을 가진 식품 및 화장품의 원료로 사용 가능성이 있다고 판단된다. This study evaluated the functional components and antioxidant activities of 21 different rose flower extracts, to confirm their value as a food and cosmetics ingredient. The highest values of total polyphenol, flavonoid and tannin contents (379.70±1.64 mg GAE/extract g, 50.10±0.76 mg CE/extract g, and 339.44±1.20 mg TAE/extract g, respectively) were obtained in Lover Shy. The proanthocyanidin content ranged from 61.88 mg CE/extract g in the Unina cultivar to 5.34±0.13 mg CE/extract g in the Aileen cultivar. The phenolic acid content obtained was highest in the Lover Shy cultivar (27.40±0.26 mg/extract g), whereas highest levels of anthocyanin (8.83±0.03 mg/extract g) were obtained in the Unina cultivar. High ABTS and DPPH radical scavenging activities were determined in the Lover Shy cultivar (428.10±0.29 and 419.59±3.12 mg AAE/extract g, respectively). Taken together, these results indicate that the antioxidant activity and functional components of Lover Shy cultivar are superior, and this extract can potentially be applied as a food and cosmetic ingredient.
