The study investigated the Integration of Information and Communication Technology (ICT) to the Library and Information Science Curriculum: The Practicum in Library Schools in Rivers State. Descriptive survey design was used with a population 374 comprising 21 LIS educators and 353 Four Hundred Level Library and Information Science Students from University of Port Harcourt, Rivers State University, Port Harcourt, and Ignatius Ajuru University of Education Port Harcourt. Census sampling technique was used to select the LIS educators and purposive sampling technique was used to the select the Four Hundred Level LIS students. Questionnaire and checklist were used for data collection. 90% and 97% responses were found valid for analysis for LIS Educators and LIS students respectively. The study was analyzed using mean rating, standard deviation and simple percentage. The study revealed that ICT courses were integrated into LIS curriculum in Library schools in Rivers State but LIS educators lacked the ICT skills to teach ICT practicum consequently, the students were not properly taught ICT practicum. However, students had positive perception of ICT practicum. Notwithstanding, lack of ICT skills, poor policy implementation, lack of state-of-the-art infrastructure and nonchalant attitudes of staff towards the adoption of ICT constituted the challenges faced in the implementation of ICT practicum. The study therefore, recommended that the management of library schools in Rivers State should implement ICT practicum by hiring competent staff maybe from computers science department to teach the practicum for the interim. Subsequently, recruitment of librarians should include strictly ICT compliant.

Automatic docking of small planing ship is a critical aspect of maritime operations, requiring accurate prediction of motion states to ensure safe and efficient maneuvers. This study investigates the use of Artificial Neural Network (ANN) to predict motion state of a small planing ship to enhance navigation automation in port environments. To achieve this, simulation tests were conducted to control a small planing ship while docking at various heading angles in calm water and in waves. Comprehensive analysis of the ANN-based predictive model was conducted by training and validation using data from various docking situations to improve its ability to accurately capture motion characteristics of a small planing ship. The trained ANN model was used to predict the motion state of the small planning ship based on any initial motion state. Results showed that the small planing ship could dock smoothly in both calm water and waves conditions, confirming the accuracy and reliability of the proposed method for prediction. Moreover, the ANN-based prediction model can adjust the dynamic model of the small planing ship to adapt in real-time and enhance the robustness of an automatic positioning system. This study contributes to the ongoing development of automated navigation systems and facilitates safer and more efficient maritime transport operations.

Taking advantage of geographical position of Korea located on the main route of world-wide service, Port Logistics Industry can be strategic industry which secures international competitiveness necessary for Korea to be hub of Northeast Asian's logistics. Along with the advent of super large container vessel, world ports environment changed from "milkway" type, which means vessel calls every port for service to "Hub & Spoke" type, which means vessel calls regional central port and feeder service for the rest ports. As environment changes, regional ports in Northeast Asia are competing each other tougher and tougher and introducing or developing port logistics information system based on state-of-the-art technology in order to adapt themselves to new environment, thus to be Hub port. Taking this situation into consideration, we want to define clearly the meaning and scope of port logistics IT and review the global trend of port logistics IT. Finally we want to find future development of port logistics IT which we have to achieve.

Currently, we are living in the era of the 4th industrial revolution. In the field of shipping industry, the MASS is a revolutionary game changer in the making arising out of such an industrial and technical innovation in the pursuit of radically challenging the pre-existing system of a human-operated vessel. Given this trend, the entire maritime regulatory regime, which has been designed by, and intertwined with, human seaworthiness, abruptly faces the most unprecedented normative confrontations now and increasingly in the coming days. As the constitution of ocean, UNCLOS, provides, every flag state is obliged to effectively exercise its jurisdiction to secure technical and human seaworthiness. Moreover, the coastal state may institute protective proceedings against vessels in respect of any violations of its laws to protect its marine environment in maritime zones of the coastal state. Further, UNCLOS acknowledges that the port state's authority extends to take administrative measures to prevent sub-standard ships from sailing within the ports or offshore-terminals of the state. These three jurisdictional functions will be required to more closely interface with each other than ever over the legal and political implications created by MASS. Although states' jurisdictional nuances are significant in this present world tilting back to protectionism, there are few articles to present jurisdictional issues of states and conceivable normative discourse with regard to MASS. This articles visits potential jurisdictional conflicts underlying MASS and tries to strike balance between contradictory interpretive approaches under UNCLOS while it is undeniable that this doctrinal research tends to strive to find justifications within the current framework of international law.

2014년 1월부터 아 태지역 Tokyo-MOU에서는 새로운 점검체제인 NIR를 도입하여 항만국통제(PSC)를 시행하고 있다. NIR의 가장 큰 특징은 기존 TF방식과 달리 회사의 안전관리수준까지 평가하여 선박의 위험도 수준을 고위험, 표준위험, 저위험 선박 등 3단계로 분류하고 그 수준에 따라 PSC 점검주기를 달리하는 것이다. 특히, 국제안전경영(ISM)코드의 안전관리체제(SMS)와 관련된 결함과 6개이상의 결함수, 출항정지이력 등은 선박의 위험도수준 평가에 큰 영향을 미치게 되었다. 이에 따라 선박과 회사들은 변화된 PSC환경에 대비하기 위하여 종전과는 다른 안전관리체제의 적절한 이행과 시스템 보장이 각별히 요구된다. 정부대행기관 및 주관청에서도 기존과는 다른 새로운 PSC 대응방안이 필요하다. 구체적으로는 선박과 회사간 유기적인 협력과 지원체제 강화, 심사주체와 객체의 변경을 통한 타성 극복, 정부대행기관에 대한 주관청의 관리감독 강화 그리고 민 관 협력체제 운영을 위한 네트워크 구축 등의 방안이 있다.

복잡한 수심을 가진 연안해역에서 조석, 바람과 파에 의해 발생된 흐름의 영향까지를 고려한 파랑모델의 도입은 대부분의 해안공학 설계나 방재 문제에 매우 중요한 요소이다. 근해역에서 수심변화에 의한 굴절 및 천수효과, 흐름에 의해 유발되는 굴절효과, 파형경사에 따른 쇄파, 회절, 바람에 의한 파의 성장, 파랑 상호간의 간섭 및 에너지 재분포 등을 다를 수 있다는 점에서 정상상태 스펙트럼 모델의 현장 적용은 지금까지 여러 모델이 다루지 못한 부분을 해소하게 될 것이다. 본 연구에서는 부만 신항만 건설이 이루어지고 있는 가덕인접의 및은 수역에 대해 파랑의 변환과정을 보다 합리적으로 해석하기 위해 스펙트럼 모델을 적용하고 기존의 모델 결과와 비교 분석하는 것을 골자로 하고 있다. 이러한 시도가 가까운 장래에 항만설계 및 방재시스템 분야에서 보다 안전하고 널리 스펙트럼 모델을 적용하게 하는 계기가 되도록 의도하였다.

Brushless Dual-Mechanical-Port Electrical Machine (BLDMPEM) is a new type of motor designed for Hybrid Electric Vehicle (HEV), which contains two mechanical ports and two electric ports. Compared with Dual-Mechanical-Port Electrical Machine (DMPEM), the brushless structure brings higher reliability and easier maintenance. In this paper, the model of BLDMPEM is discussed. In Chapter 2, the energy flow and mathematical model of BLDMPEM are analyzed. Then a novel three-phase half-bridge controlled rectifier topology and its control strategy for cruising mode of HEV based on BLDMPEM are proposed in Chapter 3. Compared with the Field Oriented Control (FOC) strategy of BLDMPEM, the proposed method does not require accurate motor parameters, and it is much simpler and easier to be implemented. At last, simulation and experiment results show the feasibility and validity of the proposed strategy.
