  • In order to provide a safe and secure electronic navigational chart information services, AIS information, information on aids to navigation, maritime safety information, weather information, information on a variety of birds such as the data fused S-100 standards-based e-Navigation system should be established. S-101 ENC implement Rendering Engine analyzes the Drawing Instruction set generated by Portrayal Engine of the S-100 General Portrayal Model for is a job to be followed to establish the e-Navigation System to implement the S-101 ENC Should be. In this paper, we analyze the Drawing Instruction of the existing S-57 ENC and S-101 ENC is the basis for the implementation of the S-101 ENC.

  • Nanoparticles of the semiconductor catalyst $Cd_xZn_{1-x}S$ were embedded into the metal organic framework MIL-101(Cr) to obtain $Cd_xZn_{1-x}S@MIL-101$(Cr) nanocomposites. These materials not only possess high surface areas and mesopores but also show good utilization of light energy. The ultraviolet-visible diffuse reflectance patterns of $Cd_xZn_{1-x}S@MIL-101$(Cr) nanocomposites showed that $Cd_{0.8}Zn_{0.2}S@MIL-101$(Cr) possessed good visible light response ability among the synthesized nanocomposites. The photocatalytic performance of the $Cd_xZn_{1-x}S@MIL-101$(Cr) nanocomposites were tested via degradation and mineralization of methylene blue in neutral water solution under light irradiation using a 300W xenon lamp. As a result, using $Cd_{0.8}Zn_{0.2}S@MIL-101$(Cr) as a catalyst, 99.2% of methylene blue was mineralized within 30 min. Due to the synergistic effect of adsorption by the MIL-101(Cr) component and photocatalytic degradation provided by the $Cd_{0.8}Zn_{0.2}S$ component, the $Cd_{0.8}Zn_{0.2}S@MIL-101$(Cr) catalyst displayed superior photocatalytic performance relative to $Cd_{0.8}Zn_{0.2}S$ and MIL-101(Cr). Furthermore, $Cd_{0.8}Zn_{0.2}S@MIL-101$(Cr) possessed excellent stability during photodegradation and exhibited good reusability. The remarkable photocatalytic performance of $Cd_{0.8}Zn_{0.2}S@MIL-101$(Cr) is likely due to the effective transfer of electrons and holes at the heterojunction interfaces.

  • 해상에서의 데이터는 디지털 수로데이터 교환 표준인 국제수로기구(IHO, International Hydrographic Organization)의 S-57을 기반으로 제작된다. 그러나 S-57은 지리정보 외의 정보를 표현하는데 한계를 나타내었다. S-57의 한계를 극복하기 위하여 다양한 해양데이터를 활용할 수 있는 시스템 체계로 수로 데이터를 위한 데이터 모델과 규격을 정의하는 S-100을 제정하였다. S-100을 기반으로 하여 수로데이터를 위한 표준으로 S-101을 제정하고 있으며, 데이터 검색 및 활용을 위한 메타데이터도 포함하여 구성하였다. S-101의 개발에 따라 S-57전자해도를 S-101전자해도로 변환이 요구되고 있으며, 이와 함께 메타데이터에 대한 변환도 필요하다. 본 논문에서는 S-57의 메타데이터 요소와 S-101의 메타데이터 요소를 비교 분석하여 메타데이터 변환모델을 제시하였다.

  • IHO has been developing S-100 and S-101 based on international standards. According to development It is expected to have a effect on the system which can be used to display information of ENC. In this study, S-100 standard completed is reviewed and S-101 in the second phase is analyzed. In conclusion, we organized the trends of S-100 and S-101 standard and the ripple effect into the system used ENC.

  • In this paper, we analyzed driver's and passenger's motions that cause driver's distraction, and recognized 10 driver's behaviors related to mobile phones. First, distraction-inducing behaviors were classified into environments and factors, and related recent papers were analyzed. Based on the analyzed papers, 10 driver's behaviors related to cell phones, which are the main causes of distraction, were recognized. The experiment was conducted based on about 100,000 image data. Features were extracted through SURF and tested with three models (CNN, ResNet-101, and improved ResNet-101). The improved ResNet-101 model reduced training and validation errors by 8.2 times and 44.6 times compared to CNN, and the average precision and f1-score were maintained at a high level of 0.98. In addition, using CAM (class activation maps), it was reviewed whether the deep learning model used the cell phone object and location as the decisive cause when judging the driver's distraction behavior.

  • 101 coding scheme, one of sliding block coding techniques, provides practically attractive features in some compression applications for image sources such as facsimile. This paper presents a new simple model of 101 coder. The results show that the entropy of the output of the 101 coder can be reduced close to the rate distortion bound of a binary first-order markov source.
