The berth and crane scheduling problem in a container terminal encompasses the whole process of assigning berth to each ship. determining the duration of berthing, assigning container cranes to each ship, and determining the specific start and end time of each crane service, for all the ships scheduled to be arriving at the terminal during a certain scheduling horizon. This problem is basically a constraint satisfaction problem in which all the constraints should be satisfied. However, it is also an optimization problem because the requested arrival and departure time should be met for as many of the scheduled ships as possible. while the operation cost of the terminal should be minimized. In this paper. I present an effective approach to solving this problem, which combines both constraint satisfaction search and iterative improvement search. I test this method on a real world container terminal problem and the results show that the method can produce better results than any other existing method.

The aim of this work was to investigate the N-terminal amino acid sequence of catechol 2,3-dioxygenase isolated from Delftia sp. JK-2, which could utilize aniline as sole carbon, nitrogen and energy source. Molecular weight of the enzyme was determined to approximately 35 kDa by SDS-PAGE. N-terminal amino acid sequence of C2,3O from strain JK-2 was $^1MGVMRIGHASLKVMDMDAAVRHYENV^{26}$, and exhibited high sequence similarity with that of C2,3O from Pseudomonas sp., Comamonas sp. JS765, Comamonas test-osteroni, or Burkholderia sp. RP007. Approximately 950-bp C2,3O was obtained through PCR using the primers derived from N-terminal amino acid sequence. Analysis of the DNA sequence revealed that the deduced 296 amino acid sequences were determined, and it showed $100\%$ identity with C2,3O from Pseudomonas sp. AW-2 and $97\%$ similarity with Comamonas sp. JS765.

Container terminal yards operate under a high degree of uncertainty as the contact point between inbound and outbound operations of vessels and external trucks. The layout, equipment operations. and job orders at the yards determine the efficacy and delays of the work, so many studies have investigated improvements in efficiency. H company, a container terminal operator developed an index called WDI to distribute work among RTGCs. The WDI is an indicator to prevent congestion in one place by equally distributing the work to each RTGC. This paper analyzes the effect of the WDI introduction and discusses the causes and results of the WDI introduction effect from quantitative and qualitative perspectives.

The measurement of Korea people's Radial-terminal region were frequently measure of the left hand of Radial-terminal region due to the most Korean's are right-handed and it occasionally showed incorrect results. Therefore, in this study, we accessed a correlation with error of measurement and reduced the measurement error invalid. We reviewed 50 adults patients, from March 2012 for a certain period of time, visited the orthopedic center for the neutral position of forearm of plain radiography and measured the left side of the distal radial-terminal region containing the terminal region of the right distal radius. Then we have compared and analysed both T-score. As a result, the lower value of left wrist were 45 out of 75 which is approximately 60% of left wrist group while the lower value of right wrist were 30 out of 75 which is approximately 40% of right wrist group.

This study focuses on prioritizing the technology needed for the Gwangyang Port automated terminal. While the world's leading ports are moving forward with the implementation of full unmanned automation and digital smartisation, South Korea is still in the early stages of this process. In order to enhance domestic smart port capabilities and technological competitiveness, the government is promoting the construction of a fully automated terminal at Gwangyang Port. This terminal will test various advanced technologies in the domestic port sector and build infrastructure capable of responding to increasingly sophisticated technologies. The study defines the concept of a smart port for Gwangyang Port and derives an advanced technology pool from domestic and international research. Expert survey and AHP analysis were used to calculate the weight of each technology attribute based on characteristics and urgency. The integration of these weights and importance scores determined the priority of technology adoption. The results showed that automation and optimisation technologies had the highest priority, while environmental and energy-related technologies ranked lower.

This paper proposes fast speaker adaptation method using artificially distorted speech in telematics terminal under the car noise environment based on eigenspace-based maximum likelihood linear regression (ES-MLLR). The artificially distorted speech is built from adding the various car noise signals collected from a driving car to the speech signal collected from an idling car. Then, in every environment, the transformation matrix is estimated by ES-MLLR using the artificially distorted speech corresponding to the specific noise environment. In test mode, an online model is built by weighted sum of the environment transformation matrices depending on the driving condition. In 3k-word recognition task in the telematics terminal, we achieve a performance superior to ES-MLLR even using the adaptation data collected from the driving condition.

The damage inspection of container surface is performed by the expert inspectors at the container terminal gate of harbor. In this paper, we substitute the expert's capability with the damage inspection system using the artificial intelligent control algorithm and vision system, so we can improve the work environment and effectively decrease the inspection time and cost. Firstly, using six CCD cameras attached to the terminal gate, whole container is partially captured according to eleven sensors aligned with the entering direction of container. Captured partial images are inspected by the fuzzy system which the expert's technology is embedded. Next, we compose partial images to be a complete container image through the correlation coefficient method. Complete container image is saved to solve future troublesome problems. In this paper, the effectiveness of the proposed system was verified through the field test.
