Pleural effusion due to hepatic cirrhosis with ascites is well known, although hepatic hydrothorax in the absence of ascites is a rare condition, the pathogenesis of which is still unknown. We report a case of hepatic hydrothorax without ascites confirmed by the intraperitoneal injection of Tc-99m mecroaggregated serum albumin (Tc-99m MAA) that demonstrated the passage of Tc-99m MAA into the right pleural cavity.

In this paper, we propose multi-frame based super resolution algorithm by using motion vector normalization and edge pattern analysis. Existing algorithms have constraints of sub-pixel motion and global translation between frames. Thus, applying of algorithms is limited. And single-frame based super resolution algorithm by using discrete wavelet transform which robust to these problems is proposed but it has another problem that quantity of information for interpolation is limited. To solve these problems, we propose motion vector normalization and edge pattern analysis for 2*2 block motion estimation. The experimental results show that the proposed algorithm has better performance than other conventional algorithms.

This paper focuses on dispatching strategy for AGVs(Automated Guided Vehicle). The goal of AGV dispatching is assigning AGVs to requested job to minimizing the delay of QCs and the travel distance of AGVs. Due to the high dynamic nature of container terminal environment, the effect of dispatching is hard to predict thus it leads to frequent modification of dispatching decisions. In this situation, approaches based on a single rule are widely used due to its simplicity and small computational cost. However, these approaches have a limitation that cannot guarantee a satisfactory performance for the various performance measures. In this paper, dispatching strategy based on multicriteria heuristics is proposed. The Proposed strategy consists of multiple decision criteria. A multi-objective evolutionary algorithm is applied to optimize weights of those criteria. The result of simulation experiment shows that the proposed approach outperforms single rule-based dispatching approaches.

FinTech, which has brought innovation to the financial industry thanks to the advancements in ICT since 2010, has contributed to the growth of the financial ecosystem and increased consumer benefits. Furthermore, there has been a growing demand for social responsibility and sustainability in financial institutions, which have a significant impact on governments, businesses, and people's lives. Despite this, many FinTech companies and traditional financial institutions are still in the early stages of establishing ESG (Environmental, Social, and Governance) management philosophy or lack long-term plans. In this study, we aim to examine the impact of ESG management on the FinTech industry, focusing on representative domestic cases, and derive policy and institutional measures to spread it in the financial industry. Specifically, we will adopt MSCI rating indicators, which are internationally accepted by various industries such as manufacturing, healthcare, and transportation, to evaluate the 35 ESG management subcategories of FinTech companies. As a result, a total of 22 compliance items were disclosed in the ESG report, and it was possible to confirm the detailed management. Through this, we intend to propose effective management strategies for the organizational structure, operations, programs, and performance evaluation of FinTech companies, which are positioning themselves as sustainable growth drivers in the domestic industry.

To testy time division scheme, we performed some experiments in a circular water tank(13m in diameter and 1m deep). A result of that is shown in figure 4. The 2-dimensional position of the pinger was calculated by the method of hyperbolic line of position calculation. The resolution of the time difference on the base line is 2.5cm. In experiments, the multiple pingers of a single frequency were distinguished and tracked successfully. When the experiment is carried out in the water tank, some multi-path pulses always occur. To delete it, several 10 ms of time delay is inserted onto the program after a group of the normal signals are received. Some normal pulses are not received by the time delay, however there is no problem, practically, for the distinction and the tracking of the pulse. In 2-dimensional positioning, the pinger position can be calculated with three hydrophones. However, if four hydrophones are available, the positioning accuracy will be higher than three hydrophones only by some techniques. Another good feature of the use of four hydrophones is that the positioning of the pinger is capable if a hydrophone fails in receiving them. We also tested this distinguishing method in the field using another type pingers(APPENDIXA).

The most famous algorithm of splitting and connecting Snake for extracting the boundary of multiple objects is the nearest method using the distance between snake points. It often can't split and connect Snake due to object topology. In this paper, its problem was discussed experimentally. The new algorithm using vector between Snake segment is proposed in order to split and connect Snake with complicated topology of objects. It is shown by experiment of two test images with 3 and 5 objects that the proposed one works better than the nearest one.

A simple numerical modelling technique is proposed for estimating the shear lag effects of framed-tube system with multiple internal tubes. The tube(s)-in-tube structure is analysed by using an analogy approach in which each tube is individually modelled by a beam that can accounts for the flexural and shear deformations, as well as the shear lag effects. The numerical analysis is based on the minimum potential energy principle in conjunction with the variational approach. The shear lag phenomenon of such structures is studied with additional bending stresses. Structural parameters governing the shear lag behaviour in tube(s)-in-tube structures are also investigated through thirty-three numerical examples.

2003년 11월에 개봉된 영화<올드보이>는, 으로 유명해진 박찬욱 감독의 복수극 3부작의 제2편으로 알려진 작품이다. 3부작의 첫 편인 <복수는 나의 것>의 연장선상에서 이 영화를 예견했던 평론가들과 관객들은 전작이 가지지 못했던 상업성까지 겸비한 이 영화의 독특한 스타일과장르, 그리고 신선한 소재에 감탄하고 열광했다.영화<올드보이>는 기본적으로 상업적으로 ‘잘만들어진(well-made)’ 영화이다. 말하고자 하는 것도 명징(明澄)해 관객들을 혼란스럽거나 지루하지 않게 만들며, ‘멜로’적요소와‘느와르’적요소, 거기에‘미스테리’요소까지 들어 있어 관객들의 시선을 쉴틈없이 붙잡아 둔다. 화려한 색감과 음울하면서도 압도적인 오리지널 사운드 트랙의 선율, 신선한 촬영기법(특히, 영화 속 최민식의 3분동안의 롱테이크‘장도리 액션’장면은 이 영화의 압권이다), 그리고중간 중간 보이는 블랙 코미디의 요소까지. 물론 이 영화를‘잘만들어지게’만든데에는 최민식이라는 배우의 뛰어난 연기력과 그외의 배우들의 호연도 큰몫을 했다. 그래서 관객들은 이 영화가 숨겨둔 ‘비밀’의 섬뜩함과 불편함에도 불구하고 이영화를 ‘재미있게’ 보러 왔다. 그 덕분에 <올드보이>는 흥행면에서 꽤 큰 성공을 거두어 300만명 이상의 관객을 동원했다. 그리고 2004년 5월 화제를 뿌리며 칸느 영화제에서 심사위원대상이라는 쾌거를 거둔다. 뿐만 아니라 2003년 청룡영화상, 2004년 대한민국영화대상 등 국내영화제에서도<올드보이>의 활약은 대단했다. 2003년흥행과 작품성 모두에서 인정을 받은<살인의추억>의 자리를 이 영화가 물려 받고 있다고 할만하다. 한마디로 말해, 우리가 늘 주목하는‘잘된콘텐츠’의 전형적인 예인 것이다. 바로 그 지점 때문에 우리는 이 영화에 대해 이야기할 필요가 생긴다.

A lot of cultured flounders died by ascitic disease blooming during the summer season in 2002, southern parts of Korea. This study was conducted to investigate the microbial flora for the ascitic cultivated olive flounder (Paralichthys olivaceus) which were collected in the Koe-je island in the southern of Korea from July 2002 to October 2003. Three Genera (Vibrio, Photobacterium and Edwardsiella), seven species of bacteria (V. harveyi, V. alginolyticus, V. parahaemolyticus, V. carcariae, V. metschenikovii, P. damsela and E. tarda) and a fish pathogenic birnavirus (marine birnavirus, MABV) were isolated from the liver, dropsy, spleen and identified by biochemical and molecular biological characterization.

인터넷상의 생물학 자원들을 이용하는 에이전트 시스템들에는 몇 가지 특징들이 있는데, 그중 하나가 바로 사용자 에이전트와 공개 데이터베이스들을 대신하는 에이전트들간의 자원 이용과정에서 발생하는 정보를 효율적으로 중계하고 조정하는 역할을 하는 기능이 존재해야 한다는 것이다. 공개 데이터베이스 자원들을 이용하는 경우 서로 다른 데이터 양식과 용어 체계, 제공하는 정보의 양과 정보를 제공하는데 걸리는 시간 등의 차이점이 존재하며, 또한 하나의 UI 에이전트로부터 복수 개의 질의를 수행하는 경우나 복수 개의 UI 에이전트들로부터 복수 개의 질의가 이루어지는 경우, 다양한 형태와 제공 정보로 인해 발생하는 자원들의 특성이 존재하게 된다. 이를 해결하기 위해서는 자원들의 다양성에 대한 고려, 메시지 트랜잭션의 관리와 더불어 다양한 플랫폼들에서 운용이 가능한 메시지 형식을 띠고 있어야 한다. 본 논문에서는 현재 개발중인 단백질 구조예측 연구를 지원하는 APSS 시스템 내에서의 사용자 에이전트와 여러 분석 및 자원 에이전트들 간의 효율적인 메시지 중재 및 조정기능을 갖는 CODY 에이전트를 설계하였고 이에 관하여 기술하고자 한다.
