Background: The purpose of this study was to determine the effectiveness of percutaneously place self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. Materials and Methods: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self-expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. Results: There were 4 cased of Bismuth type Ⅱ,21 cases of Bismuth typeⅢa 8 cases of Bismuth type Ⅲb and 15 cases of Bismuth type Ⅳ. Stent placement was technically successful in all patients All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage of 91.9% There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and median survival time were 303 days (range, 60~815) and 338 days (range, 60 ~1175), respectively. Conclusion: Placement of a percutaneous metallic stent is an effective and safe method of palliation of patients with hilar cholangiocarcinoma.

Thirty three species belonging to twenty genera in the subfamily Gobiinae of Korea were reviewed and key to species and genera were provided. Among them twenty seven species captured during 1985-1987 were examined on the cephalic sensory canal systems for the taxonomic review, and classified into 4 groups based on the presence or absence of the canal and their canal pore patterns. It was confirmed that the pore patterns of preopercular and anterior ocular-scapular canal were important in the diagnosis of gobiid genera or species and in the discussion of the specialized species group. It was considered that the genus of Acentrogobius masago should be transferred to Pseudogobius from Acentrogobius, because A. masago was more similar to P. javanicus than to A. pflaumi and its congeneric species in their cephalic sensory canal systems. Some populations of Chaenogobius annularis and Acanthogobius lactipes showed the geographical variations in cephalic pit organs and the number of predorsal scales. The endemic gobiid species was not found the Korean waters, but some species showed a disjunct distributions between the west and the east coast waters in Korea. The south coast was inhabited by the abundant species including twenty seven species of seventeen genera. The genera of Acanthogobius, Chaenogobius, and Chasmichthys were considered to be the common genera in Korean waters.

In speaker identification systems, it was proved in previous other experimental theses that the performance of GMM is better than that of any other speaker modeling techniques. The EM algorithm is used to build a GMM-based speaker identification system. This paper introduces the modified EM algorithm to enhance the identification rate. The experiments examine algorithmic issues (initialization, variance limiting and model order selection). As a result of the experiments, the modified EM algorithm achieves 95.044% identification accuracy comparing with basic EM algorithm (94.605% identification accuracy) and is shown to outperform the basic EM algorithm.

The International standard such as H.261, MPEG(Moving Picture Expert Group) has been used block-based motion estimation technique. Wavelet transform is very popular in these video processing recently, because wavelet based compression has the advantages of efficient decorrelation each consecutive image frame and reduced-complexity in multiresolution motion estimation technique (MRME). We propose a technique to improve coding performance of baseline wavelet-based coder. The motion vectors are calculated using adaptive threshold method from subimage. In order to find wrong-searched block, threshold factor is defined for comparing with energy of reference block. The experiment results show that the proposed method improved bit-rate and PSNR of decoder.

The purpose of this study examined and analyzed the historical changes of KSC and reconfirmed its effects and influences upon athletic activities in Korea and in other countries by theoretical frame based on philological way. In addition. it also presents characteristics of the changes and process of KSC and offers the visions of progress. Accordingly. the researcher made a specific purpose of the study. Firstly, a analysis on the of formation of KSC periodically. Secondly, a analysis on process of changes of KSC periodically. Thirdly, a new vision to offer for the progress of KSC. A periodical division of KSC: 1) KSC as an optional body(1915-1953). 2) KSC as a corporation(1954-1967). 3) KSC as an integration body(1968-1982), 4) KSC as a special corporation(1988-now). This study offers the visions for progress of KSC. The results of this study were as follows: 1) re-establishment an idea of physical education. 2) make healthy policies and systems of physical education. 3) integration of KSC and NACOSA. 1) separation KSC from KOC. 5) expansion of finance of physical education. 6) improvement of financial independence of member organizations. In conclusion. KSC has to be an organization of physical education and athletics for all the people, balancing with historical progress and according with purposes of the enterprise, it also has to improve its ability to do the duty and roles as a leader which generalizes physical education and athletics in Korea.

In this paper, design and construction of mobile robot are conducted and the error reduction and obstacle avoidance techniques are introduced. Up to now, in the design of most mobile robots, there is emphasis on the compensation of tracking errors using the additional sensors and guidance method, rather than the reduction of the tracking errors of motor itself and wheel errors. In this purpose, high performance motor and encoder are used for the driving actuator, and the acceleration/deceleration technique and caster encoder are introduced to reduced the driving errors. Also ultrasonic sensor performs obstacle avoidance, which is proved using the driving test.

In this study, the bone mineral density (BMD) of the femoral neck, trochanter, Ward's Triangle and lumbar vertebrae, and were measured using dual photon absorptiometry and the results compared in healthy young males involved in indoor ball games. The results were as follows. 1. In the priority of order among college indoor ball game players, the lumbar vertebra BMD was highest in those engaged in volleyball(mean 1.4814±0.1531)g/㎠ and 1.4441±0.1314g/㎠ in handball, 1.3394±0.1271g/㎠ in basketball, 1.1585±0.0273g/㎠ in college students respectively.(P<01) 2. In the priority of order among college indoor ball game players, the femoral neck BMD was highest in those engaged in volleyball(mean 1.4503±0.0652)g/㎠ and 1.3749±0.0825g/㎠ in handball, 1.3040±0.1624g/㎠ in basketball, 1.2807±0.1543g/㎠ in college students respectively. (P<5) 3. In the priority of order among college indoor ball game players, the Ward's Triangle BMD was highest in those engaged in volleyball(mean 1.3775±0.0637)g/㎠ and 1.3149±0.824g/㎠ in handball, 1.2443±0.1588g/㎠ in basketball, 1.1585±0.0273g/㎠ in college students respectively.
