In special effects industry there is a high demand to convincingly mimic the appearance and behavior of natural phenomena such as smoke, waterfall, rain, and fire. Particle systems are methods adequate for modeling fuzzy objects of natural phenomena. This paper presents particle system graphics library for generating special effects in video games and virtual reality applications. The library is a set of functions that allow c++ programs to simulate the dynamics of particles for special effects in interactive and non-interactive graphics applications, not for scientific simulation.

This research presents a method for the initial structural design of a multi-megawatt wind turbine blade. The structural data for a 2-MW blade were applied as the blade structural characteristic data of the reference blade. Tenkinds of blade models were newly designed by replacing the spar cap axial GRRP with a GFRP and CFRP These terms should be defined. at different orientations. The axial stiffness coefficients of the newly designed models were made equal to the coefficient of the reference blade. The required numbers of layers in each section of blades were calculated, and the lay-up designs were based on these numbers. Verification results showed that the design method that used the structural data of the reference blade was appropriate for the initial structural design of a wind turbine blade.

The purpose of this research is to grasp the present state of marine lifelong education and to provide direction for maritime industry. In this research, we first saw our country present ocean industry and the ocean lifelong education concept and definition besides formal school education to secure ocean human capital. Second, we researched about the ocean lifelong education that has been progressing by the organization, and by this, we inferred what to improve from our country ocean lifelong education. As a result, the improvement point for present ocean lifelong education of our country was first, the reflect of variety of marine related information in our country lifelong education is low, second, the learners were mostly children and teenagers, third, most of the were event education. Forth, it is good that there are a lot of experimenting programs, but most of them were experiment of ocean leisure sports and visiting the facilities, and because these are one-time thing so it was hard to secure marine citizenship or help them set their career in marine. Fifth, all facilities had similar contents for the experimenting program, and sixth, education period was concentrated on May and November.

This study aims to investigate changes in the demand for ship officers in response to changes in the shipping industry environment in which Maritime Autonomous Surface Ships (MASS) emerge according to the application of the fourth industrial revolution technology to ships, and it looks into changes in the skill of ship officer. It also analyzes and proposes a plan for nurturing ship officers accordingly. As a result of the degree of recognition and AHP analysis, this study suggests that a new training system is required because the current training and education system may cover the job competencies of emergency response, caution and danger navigation, general sailing, cargo handling, seaworthiness maintenance, emergency response, and ship maintenance and management, but tasks such as remote control, monitoring diagnosis, device management capability, and big data analysis require competency for unmanned and shore-based control. By evaluating the importance of change factors in the duties of ship officers in Maritime Autonomous Surface Ships, this study provides information on ship officer educational institutions' response strategies for nurturing ship officers and prioritization of resource allocation, etc. The importance of these factors was compared and evaluated to suggest changes in the duties of ship officers and methods of nurturing ship officers according to the introduction of Maritime Autonomous Surface Ships. It is expected that the findings of this study will be meaningful as it systematically derives the duties and competency factors of ship officers of Maritime Autonomous Surface Ships from a practical point of view and analyzed the perception level of each relevant expert to diagnose expert-level responses to the introduction of Maritime Autonomous Surface Ships.

This study presents the analysis of relationship between ship speed and local ice load on the Korean Icebreaker ARAON. The relationship curves were made from the data obtained at two areas: the Arctic and the Antarctic; and for two operation condition: the icebreaking condition in sea ice trial and general operation in ice covered sea. The strain data were converted to the equivalent stress value, and the influence of ship speed on the local ice load was analyzed and compared each other. These analysis results are useful in working on a statistically valid hull design approach.

The shock wave process represents an abrupt change in fluid properties, in which finite variations in pressure, temperature, and density occur over the shock thickness which is comparable to the mean free path of the gas molecules involved. This shock wave fluid phenomenon is simulated by using the finite difference lattice Boltzmann method (FDLBM). In this paper, a new model is proposed using the lattice BGK compressible fluid model in FDLBM for the purpose of speeding up the calculation as well as stabilizing the numerical scheme. The numerical results of the proposed model show good agreement with the theoretical predictions.

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.

The paper reviews briefly of the codes above, together with the effects of the successful introduction of the QMS into the shipping industry. This paper suggests a conceptual prototype for a quality management system (QMS) of seafaring labour, which itself would be a sub-system of the total quality management (TQM) system in a shipping company, on the basis of the ISM and the ISMA Codes, ISO 9002, ISO 9004, and other quality management guidelines. The QMS is essential for the survival of the Korean shipping industry. It will contribute not only to assuring the quality of crew, but also, consequently, to increasing the international competitive edge of the shipping companies in Korea.
