The port, differently from general working place, is a closed area to execute security, customs, and quarantine procedures. The loading and unloading is being done differently by cargoes, ships, berths, and equipments. To load and unload a lot of equipments and different types of labor are required, in which work flow is very complicated. As above mentioned the port is very unique and deteriorated working place including danger. The purpose of this thesis is to propose ways to analyze and establish the preventive measure for cargo handling accidents in port. We have collected 923 accidents happened at Incheon Port during the period from 1994 to 2003. And to analyze and establish the preventive measure we have employed an advanced 6sigma DMAIC technology presently in spotlight as the best tool for management innovation. For the purpose of effective safety management of cargo handling in port, this thesis will help to revise and establish the law, system, standard, and standard working manual with respect to the port loading and unloading system. Now frequency of cargo handling accidents in port is highest for the second time among all industries, so we proposed the new safety management system to substitute port safety committee and to take full charge of safety in Ministry of Maritime Affairs and Fisheries.

Since traffic congestion ratio at any given port fluctuates on the number of arriving and departing vessels, the total tonnage of freight volume being handled, and the number of berth in operation and other factors, there exists a need to numerically analyze the waterway traffic volume. However, there are no effective regulations in regards to the waterway traffic analysis prior to expansion of a port facility. The current analysis requires the traffic analysis in relation only to the width of the waterway, which clearly falls short of achieving a comprehensive evaluation study that could be used in consideration of port expansion.This study provides five scenarios to execute a comprehensive evaluation study and base for the sensitivity study by analyzing the scenarios. As a result of the sensitivity analysis, the A, B, and C scenarios varies the average arrival ratio of the berth shows 1.1, 1.19, and 1.28 times of delays respectively. Also, The D and E scenarios take place malfunctions of pier shows 1.21 and 1.53 times of delays respectively. Therefore, various strategies of harbor development and method of harbor management are needed for the flexible correspondence to the environmental changes such as the excessive increasing of the freight volume and often taking place of malfunctioning.

The instability of rock slopes caused by heavy rainfall and soil mass sliding needs the preventable and reinforcing method. The most important factor for the stability is the shear strength available in the planar part of the failure surface, which shows that a progressive failure takes place and a reinforcing of rock slope using FRP grout is effectively available. In this study, a grouting bolting interval predictions by limit equilibrium analysis and Matlab mathematical computer codes in several cases is presented for FRP reinforced rock slope. The proposed mathematical computer code can be easily applied for seeking properly FRP grout intervals prior to design and execute a reinforcement of a rock slope in practice.

플래시 메모리는 하드 디스크와 여러 면에서 다른데 특히 덮어쓰기가 되지 않는다는 것이 가장 큰 차이점이다. 그로 인해 대부분의 플래시 메모리 파일 시스템들은 파일을 수정할 때 not-in-place 수정 기법을 사용하고 있다. 그 과정에서 가끔 플래시 메모리 파일 시스템들은 가용 공간의 확보를 위해 무효 페이지들이 많은 블록들의 유효 페이지들을 다른 블록으로 옮기고 블록들을 쓸 수 있는 빈 페이지로 만들어 주는 작업인 블록 클리닝 작업을 수행한다. 블록 클리닝 작업은 플래시 메모리의 성능을 직접적으로 좌우하는 요소이다. 그래서 이 논문은 유효 페이지와 무효 페이지를 동시에 가진 블록의 수를 최소화하여 블록 클리닝 비용을 줄일 수 있는 효율적인 페이지 할당 기법을 제안한다. 그리고 실험 결과는 원래의 YAFFS에 비해 블록 클리닝 비용이 확연하게 줄어들었음을 보여 준다.

Recently, an embedded flash memory has been widely used for the Internet of Things(IoT). Due to its nonvolatility, economical feasibility, stability, low power usage, and fast speed. With respect to power consumption, the embedded memory system must consider the most significant design factor. The objective of this research is to design high performance and low power NAND flash memory architecture including a dual buffer as a replacement for NOR flash. Simulation shows that the proposed NAND flash system can achieve better performance than a conventional NOR flash memory. Furthermore, the average memory access time of the proposed system is better that of other buffer systems with three times more space. The use of a small buffer results in a significant reduction in power consumption.

Chinese law does not directly stipulate the criteria for determining the nationality of arbitral awards, and the Civil Procedure Law stipulates that arbitral awards are divided into domestic arbitral awards and foreign arbitral awards based on the location of the arbitration institution managing the arbitration cases. This indirectly classifies the nationality of the arbitral award based on the location of the arbitral institution. However, with regard to the nationality of eight arbitral awards in this paper made in China by the foreign arbitration institutions, the Chinese courts determined the nationality by arbitrarily selecting the criteria for the location of the arbitration institution and the criteria for the place of arbitration, except for arbitral awards made in Hong Kong. China's unclear attitude toward the criteria for determining the nationality of arbitral award has resulted not only obscures the country that can exercise the right to revoke arbitral award, but also obscures the laws and regulations applied to the approval and execution of arbitral awards. In other words, since the right to revoke the arbitral awards resides with the country of nationality of the awards, such an ambiguous attitude in China prevents the parties from responding to the cancellation lawsuit by predicting the nationality of the arbitral awards in advance. Furthermore, since China made a declaration of reciprocity reservations while joining the New York Convention, in cases where the criteria for location of the arbitral institution is applied, if the arbitration institution belongs to a contracting state, the it must apply the New York Convention to approve and execute arbitration decisions, but if it is not a contracting state, it must be approved and executed by mutual arbitration agreements or reciprocity principles. These results can lead to different results in approval and execution of the same arbitral awards depending on how the nationality is determined.
