From a sustainability perspective, the characteristics of upcycling fashion design by Marine Serre were analysed to understand upcycling fashion design, which can be an important way to follow sustainability values in the fashion industry, and to provide solutions for moving towards sustainable fashion. In order to derive the characteristics of upcycling fashion design from a sustainability perspective, the values of sustainable designs and the characteristics of the upcycling design were derived though the analysis of Marine Serre's seasonal collections from the 2018 F/W season to the recent 2022 F/W season. The research results are summarized as follows. First, the value of sustainable fashion design could be classified into environmental, economic, social, and cultural values. Second, Marine Serre's upcycling fashion design was driven by the characteristics of sustainable upcycling fashion design, such as environmentality, originality, variability, economy, handicraft, time, and availability. Third, Marine Serre's upcycling fashion design contained all environmental, economic, social, and cultural sustainability values. From a sustainability perspective, Marine Serre's upcycling fashion design can be said to be an upcycling fashion design with convergent values that encompasses all of the sustainability core values of environmental, economic, social, and cultural aspects.

현대의 일러스트레이션 디자인은 독창성을 필요로 하는데, 해양생물의 형태와 색채는 일러스트레이션 창작에 풍부한 소재를 제공한다. 일러스트레이션은 디자인적 창조 가치가 매우 높다. 본 연구는 해양생물을 거울삼아 색채학적 지식과 시각적 형태설계를 통해 이를 밝히고, 일러스트레이션 디자인과 해양생물을 주요 연구대상으로 하였다. 본 연구목적은 ① 해양생물의 전형적 특징을 색과 형태 중심으로 정리, ② 이를 해양생물을 대표하는 그래픽 기호로 도출하여, ③ 일러스트레이션으로 접목할 수 있음을 해양생물 일러스트레이션 제작으로 사례를 제시하였다. 연구를 통해서 결론을 도출하고, 해양생물과 육지생물을 구분하는 전형적인 특징 중 하나로 곡선적인 특징을 부각시켰다. 열대어 색채 현상에 대한 분류 연구와 비교분석을 통해 도출한 열대어류의 색채 특성을 바탕으로 해수 열대어의 색채를 추출 및 가공하여 일러스트레이션 디자인에 활용할 수 있다.

The number of marine accidents have been decreased since various equipments for navigation control have been introduced to the marine vessels. However, disastrous marine accidents such as ship collisions are occurred more frequently. Therefore, IMO(International Maritime Organization) is enforcing the design requirement of structural strength for marine vessel. Also EU countries are developing new design methodologies and design tools to suggest the design guidance which can minimize the damage of commercial vessels in case of marine collision accidents. In this study, an integrated design system for the safety assessment has been presented to enhance the safety of damaged ships in marine collision accidents. The architecture of system is described by use-cases and IDEF functional analysis. Then an integrated system for safety assessment of damaged ship which is considering both damage stability and structural safety has been developed to support the ship design in early stage.

An Independent Administrative Corporation Japan Agency for Marine-Earth Science and Technology (JAMSTEC) is developing light-and-small Autonomous Underwater Vehicles (AUV)$^{1)}$, named 'MR-X1' (Marine Robot Experimental 1), which can cruise, investigate and observe by itself without human's help. In this paper, we consider the motion control problem of 'MR-X1' and derive a controller. Since the dynamic property of 'MR-X1' is changed by the influence of the speed, the mathematical model of 'MR-X1' becomes the nonlinear model. In order to design a controller for 'MR-X1', we generally apply nonlinear control theories or linear control theories with some constant speed situation. If we design a controller by applying Linear Quadratic (LQ) optimal control theory, the obtained controller only compensates t e optimality at the designed speed situation, and does not compensate the stability at another speed situations. This paper proposes a controller design method using Linear Matrix Inequalities (LMIs)$^{2),3),4)}$, which can adapt the speed variation of 'MR-X1'. And examples of numerical analysis using our designed controller are shown.

For the reuse of the existing 3D block model of a ship, we analyze the hull modeling process using AVEVA Marine which is a representative CAD (Computer-Aided Design) system for the shipbuilding. In the AVEVA Marine environment where the design engineer makes 3D model on the 2D view that is so-called 2.5D, it cannot be possible to copy to reuse the block model just simply copying the 3D feature model itself like in the general mechanical CAD system or Smart Marine 3D which are on the basis of the 3D model representation. In this paper, we analyze the scheme file where the 3D model is defined in AVEVA Marine so that we develop the program for the block copy and the translation using this scheme file. It is significant that this program can be immediately available as a real-world application on the AVEVA Marine environment.

Harbour marine steel structures, which are served in severe marine environment, should be protected in appropriate method to reduce corrosion problems. Cathodic protection, one of the protection methods in terms of practical and economical point of view is being widely used to marine steel structures mentioned above. Recently it has been reported that the life of Al alloy anode with sacrificial anode for protection of harbour marine steel structures was shortened significantly than the original design life. In this study, the optimum cathodic protection design of harbour marine steel structures was investigated with parameter of sea water pollution degree.

The assessment of the potential for the design of marine renewable energy systems is reviewed and the current situation for marine renewable energy is promising. The most studied forms of marine renewable energy are ocean wind energy, ocean wave energy and tidal energy. Wind turbine generators include mostly horizontal axis type and vertical axis type. But also more exotic ideas such as a kite design. Wave energy devices consist of designs converting wave oscillations in electric power via a power take off equipment. Such equipment can take multiple forms to be more efficient. Nevertheless, the technology alone cannot be the only step towards marine renewable energy. Many other steps must be overcome: policy, environment, manpower as well as consumption habits. After reviewing the current conditions of marine renewable energy development, the authors analyzed the key factors for developing a strong marine renewable energy industry and pointed out the huge potential of marine renewable energy.

To predict the consolidation behavior of dredged and reclaimed marine clays exhibiting consolidation settlement with large strains, the finite strain consolidation theory must be used. However, challenges in appropriately applying the theory and determining input parameters make design and analysis studies difficult. To address these challenges, design charts for predicting the consolidation settlement of reclaimed marine clays are developed by a numerical approach based on the finite strain consolidation theory. To prepare the design charts, a sensitivity analysis of parameters is performed, and influencing parameters, such as initial void ratio and initial height, as well as the non-linear constitutive void ratio-effective stresspermeability relation, are confirmed. Six representative Korean marine clays obtained from different locations with different liquid limits are used. The design charts for estimating the consolidation times corresponding to various degrees of consolidation are proposed for each of the six representative clays. The consolidation settlements predicted from the design charts are compared to those in previous studies and at an actual construction site and are found to agree well with them. The proposed design charts can therefore be used to solve problems related to the consolidation of reclaimed marine clays having large strains.

This paper presents a structural design review of a marine loading arm used for the fluid transfer of a liquid cargo from a ship or offshore plant. The marine loading arm is installed on a ship, offshore plant, or jetty in order to load or unload liquid cargo such as crude oil, liquefied natural gas (LNG), chemical products, etc. The structural design of this marine loading arm is obliged to comply with the design and construction specifications regulated by the oil companies and international marine forum (OCIMF). In this paper, the structural safety of the initial design for the marine loading arm is evaluated for the design load conditions required by various operational modes. The evaluated results based on a finite element analysis (FEA) are reviewed in relation to the OCIMF specifications.
