This paper proposes an evaluation to Target Factor Values of Port State Control Inspections(PSCITFV) using AHP because PSCITFV is very simple methode, This AHP is the more rational and objective methode than existing TFV methode. AHP is relative measurement., but, weights should be re-calculation whenever alternative plan add. To this solve, therefore, this paper, used an absolute measurement and involved an marine casualty factor in PSCITFV, that IMO go ahead with it., Also, accomplished with evaluation some ships for the practice.

항만국통제는(Port State Control)은 자국 항만 또는 수역 내에서 기준미달선을 제거하기 위하여 선박이 외국항에 기항하였을 때 해당 항만국의 검사관(Port State Control Officer)이 승선하여 그 선박이 국제협약 또는 항만국의 규정에 적합하게 건조, 정비 및 운용되고 있는지를 확인하고 결함사항이 발견된 선박에 대하여 억류 등의 제제조치를 가하는 제도이다. 최근의 항만국통제는 기항 선박에 대한 Target Matrix를 활용한 점검대상 선박 선정, 집중점검프로그램 운용 및 목표 점검율 상향조정 등으로 항만국통제 활동은 점점 더 강화되고 있다. 우리공단 검사선박의 경우 PSC에 의한 출항정지 척수가 2006년 1척, 2007년 2척 그리고 2008년 4척으로 점차 증가하는 경향을 보이고 있다. 따라서 공단 검사선박의 출항정지율 저감을 위한 방안을 개발하기 위하여 Paris MOU, Tokyo MOU 그리고 USCG의 최근 PSC 점검동향과 우리 공단의 검사선박중 출항정지 선박 및 지적된 결함사항에 대하여 조사 분석한 결과 최근 7년간 출항정지 당한 선박 10척중 6척이 도입선과 2척이 탈급선이고 그리고 주요 지적사항으로는 만재흘수선 관련 결함사항이 가장 많이 지적되었음으로 분석되었다. 따라서 그러한 분석 결과를 바탕으로 공단 검사선박의 출항정지율 저감을 위한 대책을 검토하고 새로 도입되거나 개선되어야 할 점 등에 대한 안을 제시하였다.

In this work, we have studied about an RSFQ (Rapid Single Flux Quantum) switch element. The circuit was designed, simulated, and laid out for mask fabrication. The switch cell was composed of a D flip-flop, a splitter, a confluence buffer, and a switch core. The switch core determined if the input data could pass to the output. “On” and o“off” controls in the switch core could be possible by utilizing an RS flip-flop. When a control pulse was input to the “on” port, the RS flip-flop was in the set state and passed the input pulses to the output port. When a pulse was input to the “off” port, the RS flip-flop was in the reset state and prevented the input pulses from transferring to the output port. We simulated and optimized the switch element circuit by using Xic, WRspice, and Julia. The minimum circuit margins in simulations were more than $\pm$20%. We also performed the mask layout of the circuit by using Xic and Lmeter.

The purpose of this paper is to shed the light on one of the most important influential factors for the development the Palestinian economy, which is logistics system. The discussion about the Palestinian state and its economy arise after the UN General Assembly voted to grant Palestine a nonmember state. Palestine is considered land-locked country, although it has seashore. Although Palestine has seashore, it is considered land-locked country due to the lack of sovereign logistics infrastructure. International Trade with Israel, Jordan, and Egypt is done through land border crossings. Palestinian international trade to European, Asian, and American countries is currently done through Israeli airports and seaports. Almost 99% of the Palestinian imports are through land. Israeli policies and procedures incur Palestinian exports additional transportation costs when delivering their products to Israeli ports and Airport and even when transit these cargos to neighboring countries through Israeli controlled areas. Therefore, without direct access to international markets, the Palestinian economy will not be able to compete in international markets, and will continue its dependence on the Israeli economy. Considering that the current situation will continue, alternative routes for international trade to avoid using the Israeli ports are Aqaba Port in Jordan and Port Said in Egypt. In the long term, having a seaport and Airport in Gaza, Airport in the West Bank, and constructing the Corridor connecting Gaza and the West Bank, is the only solution capable for independently integrating the Palestinian economy with the region and other countries in the world, and therefore creating competitive advantage for the Palestinian exports.

In order to effective manage the construction, disaster prevention plan and the harbor tranquility control, meteorological and sea-state characteristics around Cheju Island have been analyzed. Using results and damage examples of the port facilities under severe sea conditions, a reasonable construction control plan considering the regional characteristics of the sea-state and winds was proposed. That is, in northern part of Cheju Island, the construction work is affected mainly by the winter storms, while the typhoon mainly affects the southern part port facilities during summer to Autumn. Considering their typical characteristics, it is strongly suggested that the main construction work should be carried out during April to July in the northern part, and it should be made during October to next July in the southern part of the island. A permeable TTP mounded breakwater was constructed to protect severe waves as a temporal structure under the long-term development plan in Sogipo port. The transmission characteristics of the structure was discussed using the experimental results. The results show that the transmission coefficient $K_{t}$ is over 20% of incident waves, which cause many problems in the cargo handling in relation to harbor tranquility. In conclusion, this kind of permeable structure can be used only as a temporal structure for the disaster prevention under the construction process. It causes many problems in harbor tranquility if it is used as a permanent harbor structures.s.

Bans on TBT based antifouling paints have been drafted since 1999 by meetings 42, 43, 45 and 46 for the MEPC (Marine Environmental Protection Committee) of the International Marine Organization, and decided finally at a Diplomatic Conference of the IMO in October 2001. It was a key issue that there should be a global prohibition on the application of organo-tin compounds as biocides in Anti-fouling systems by Jan. 2003, and a complete prohibition on te presence of organo-tin compounds on ships by 1 Jan. 2008. This paper suggests a method to design International Anfi-fouling system cretificate, Record of anti-fouling system, Endorsement of the Records, Declaration on Anti-fouling System, Port State Control and reform(legislative) associated a law.

This paper presents the three-port DC-DC converter modeling and controller design procedure, which is part of the solid-state transformer (SST) to interface medium voltage AC grid to bipolar DC distribution network. Due to the high primary side DC link voltage, the proposed converter employs the three-level neutral point clamped (NPC) topology at the primary side and 2-two level half bridge circuits for each DC distribution network. For the proposed converter particular structure, this paper conducts modeling the three winding transformer and the power transfer between each port. A decoupling method is adopted to simplify the power transfer model. The voltage controller design procedure is presented. In addition, the output current sharing controller is employed for current balancing between the parallel-connected secondary output ports. The proposed circuit and controller performance are verified by experimental results using a 30 kW prototype SST system.

China's Marine Industry are growing up gradually as China's economy has advanced. Also China's Sipping Industry has been advanced. China Sipping Company is going to become a top 5 of world marine industry. China's Marine Industry has supervised and controled a manager under the mechanism of market economy. China's Marine Industry has been changed from the state-owned marine enterprise affected by government and government has effected on the formation of the board of directors and manager. So, the supervision function of the board of directors was reduced. The executive' role is emphasized when possessing the state-owned enterprise through disposal or auction, or when inducing the participation of foreign attraction. It is desirable for the Chinese director and officer to prepare for the claims internationally due to the international economic actions, , westernization of the public's consciousness about the compensation for damage followed by the increasing national income, and to prepare the increasing demand of cases due to increasing lawyers.
