W-CDMA 하향 링크에서 다수의 송신 안테나가 있을 때, 레일리 페이딩 채널에서 이동국 다중 경로 검색기의 설계 및 성능을 분석한다. 이론적 분석을 확증하기 위해, 송신 안테나가 1개, 2개, 그리고 4개일 경우 송신기 및 수신기 구조를 제시하고, 컴퓨터 시뮬레이션으로 수신동작특성(ROC, receiver operating characteristics)을 구하여 이론 값과 비교 및 분석을 한다. 또한 double-dwell 직렬 검색기의 파라미터들을 송신 안테나 수에 따라 최적화하는 절차를 제안한다. 이론적 성능 분석 및 시뮬레이션 결과는 송신 안테나가 4개 이상일 경우 post-detection 적분이 필요 없으며, 송신 다이버시티 차수가 증가한다고 항상 검출(detection) 성능이 향상되는 것은 아니고, 오히려 수신 파일럿의 수신 세기가 상대적으로 작을 때는 송신 안테나 수가 증가할 때 검출 성능이 저하되기도 함을 보인다. 본 논문의 성능 분석 결과는 송신 다이버시티 차수를 증가시키는데 매우 실제적인 기준을 제공한다. In this paper, we present the performance analysis of a multi-path searcher operating over Rayleigh fading channels when multiple transmit antennas are employed in the down-link of W-CDMA system. The simulation results for the receiver operating characteristics (ROC) for 1, 2, and 4 transmit antennas are presented to corroborate the theoretical analyses. We also propose a procedure to find the optimum parameters of double-dwell serial searcher according to the number of the multiple transmit antennas. Our analyses and simulations indicate that post-detection integration is not necessary when the number of transmit antennas is more than two. Finally, we found that increasing transmit diversity order does not necessarily improve the detection performance when the received pilot signal strength is relatively low. Therefore, this gives us a practical criterion on increasing transmit diversity order.

Objectives The purpose of this study is to investigate the effects of Crataegi Fructus Pharmacopuncture(CFP) on the adipogenesis in 3T3-L1 cells, lipolysis in rat epididymal adipocytes and histological changes in porcine adipose tissue. Methods Inhibiton of preadipocyte differentiation and/or stimulation of lipolysis play important roles in reducing obesity. 3T3-L1 preadipocytes were differentiated with adipogenic reagents by incubating for 3days in the absence or presence of CFP ranging from 0.01 to 1mg/mL. The effect of CFP on adipogenesis was examined by measuring GPDH activity and by Oil Red O staining. Mature adipocytes from rat epididymal fat pad was incubated with CFP ranging from 0.01 to 1mg/mL for 3 hrs. The effect of CFP on lipolysis was examined by measuring free glycerol released. Fat tissue from pig skin was injected with CFP ranging from 0.1 to 10mg/mL to examine the effect of CFP on histological changes under light microscopy. Results The following results were obtained from present study on adipogenesis of preadipocytes, lipolysis of adipocytes and histological changes in fat tissue. 1. Crataegi Fructus Pharmacopuncture inhibited adipogenic differentiation at the concentration of 1.0mg/mL. 2. Crataegi Fructus Pharmacopuncture decreased the activity of glycerol-3-phosphate dehydrogenase(GPDH) at the concentration of 0.1mg/mL. 3. Crataegi Fructus Pharmacopuncture ok. lipolysis at the concentration of 0.1mg/ml. 4. Crataegi Fructus Pharmacopuncture ranging 0.1 to 10mg/mL failed to exert lysis of cell membrane in porcine fat tissue. Conclusions These results suggest that Crataegi Fructus Pharmacopuncture at relatively high concentration inhibited adipogenesis and increased lipolysis of adipocytes. However, Crataegi Fructus Pharmacopuncture didn't exert any effect on lysis of cell membrane in fat tissue.

According to the increase of container flows and the appearance of large-sized container vessels, the container handling equipment in ports is evolving continuously. This research introduces the simulation model for evaluating in detail the mechanical productivity of container cranes. The model considers a single trolley and dual trolleys as the mechanism of a container crane and a single lift, a twin lift, and a tandem lift as the spreader type of it. Additionally, the detail specifications such as the dimension and the speed of a container crane are inputted and the kinematic characteristics of it are simulated. The model also considers the size of a vessel, the storage position of containers in the vessel, and the weight of containers as external physical constraints. Experimental conditions can be configured conveniently because various parameters in the model are separated. Moreover, the model can accommodate flexibly new equipment types and the changes of the existing equipment because it is designed and developed in object-oriented concept.

원승환 ( Seung Hwan Won ),조성우 ( Sung Woo Cho ),이주호 ( Joo Ho Lee ) 한국해운물류학회(구 한국해운학회) 2015 해운물류연구 Vol.31 No.2

부산항은 해상운송에 대한 접근성이 매우 우수하지만 중국 항만의 위협에 따른 최근의 환경 변화에 대응하기 위해 인프라, 장비, 운영 등의 측면에서 종합적인 대응 전략이 필요하다. 본 연구는 컨테이너선의 대형화에 초점을 맞춘 부산항의 대응 방안을 제안하고자 한다. 먼저 선박 대형화가 항만에 미치는 영향을 정리한다. 선박이 대형화됨에 따라서 보다 깊은 수심의 확보, 선석 길이의 증가, 하역장비 사양의 변화, 하역 생산성의 향상 등이 요구된다. 이어서 최근 부산항에 입항하였던 선박 자료를 조사하여 부산항의 대형 선박 입항 현황을 파악하고 미래의 상황을 추정한다. 또한 부산항의 현재 선박 수용 환경을 토대로 선박 대형화가 보다 가속화될 미래에 대형선박을 수용 가능할지를 분석한다. 이상의 분석을 기반으로 컨테이너선 대형화에 따른 부산항의 대응 방안으로 입출항 해협 및 안벽전면의 수심 확보를 통한 접안 조건의 개선, 선박 길이의 증가에 따른 선석의 재배치, 선폭 증가에 따른 하역장비 사양의 변화, 선박의 평균 처리량 증가에 대비한 생산성의 혁신 등이 제시된다. As the size of trade between countries increased, there are rapid changes in the logistics environment concerning ports. The world container handling volume in 2013 is 642 million TEUs, which grew by 80 percent compared to 360 million TEUs in 2004. It is forecasted to reach 840 million TEUs in 2018, which grew by over 2 times compared to the amount in 2004. Due to this, the marine transportation industry has made Mega-Carrier appear through mergers and acquisitions between shipping lines to expand market dominance, and they are continuing to make enormous investments for securing mega ships over 10,000 TEUs in order to strengthen the competitiveness in shipping cost. According to such changes in the shipping environment, large ports in the world are engaging in fierce competition for hub ports by continents in order to attract mega fleet, and this is leading to the trend of strengthening port competitiveness through the securing and operation of efficient port facilities. In other words, the world’s leading ports such as Singapore, Shanghai, Hong Kong, Shenzhen, Busan, Rotterdam, and Hamburg are not only developing large-sized terminals but also investing highly productive handling equipment for the efficiency of port operation. By the requirements of shipbuilders and shipping companies, very large container ships are becoming a reality, and 20,000 to 30,000 TEUs or more ultra large vessels are also expected a few years after. In these situations, the world’s major ports are faced with important challenges. The provision of container terminal infrastructure has to be enhanced to reduce the time that vessels need to stay in port. It is imperative for container ports and individual terminals to be efficient in order to survive in today’s competitive environment. Busan Port has a very excellent accessibility to international intermodal transportation network but is facing a serious threat from the rapid growth of Chinese Ports. Now Busan Port needs the total counter-strategies considering infrastructure, equipment, and operation. The objective of this research is to propose the counter-strategies of Busan Port against growing container vessel size. In order to achieve the objective, we firstly summarize the effects of growing container vessel size on ports. The enlargement of vessels requires deeper water level, longer berth length, bigger container handling equipment, and higher handling productivity. Second, we analyze the calling situation of large container vessels at Busan Port by investigating the historical data of vessels which recently called at Busan Port, and also estimate the future status of Busan Port. Third, we also analyze the calling acceptability of large container vessels at Busan Port in the future based on the current calling conditions of Busan Port. Finally, we suggest the counter-strategies of Busan Port against the expansion of container vessel size based on the results of analyses: the improvement of berthing condition through keeping deeper water level of sea route and quay inside the ports, the rearrangement of berths according to longer vessel length, the specification acceptance of container handling equipment according to wider vessel width, and the innovative improvement of productivity against increasing the average handling amounts of vessels.
