Present-day rules and regulations for the design and construction of ships are almost without exemption of a prescriptive and deterministic nature. Often it is argued that this situation is far from ideal; it does no right to the advances, which have been made during the past decades in engineering tools in marine technology, both in methodology and in computational power. Within IMO this has been realized for some time and has resulted in proposals to use Formal Safety Assessment(FSA) as a tool to improve and to modernize the rule making process. The present paper makes use of elements of the FSA methodology, but instead of working towards generic regulations or requirements, a Risk Assessment Approach, not unlike a 'safety case'; valid for a certain ship or type of ship is worked out. Delft University of Technology investigated the application of safely assessment procedures in ship design, in co-operation with Anthony Veder Shipowners and safety experts from Safely Service Center BV. The ship considered is a semi-pressurized-fully refrigerated LPG carrier. On the basis of the assumption that a major accident occurs, various accident, scenarios were considered and assessed, which would impair the safety of the carrier. In a so-called Risk Matrix, in which accident frequencies versus the consequence of the scenarios are depicted, the calculated risks all appeared lo be in the ALARP('as low as reasonable practicable') region. A number of design alternatives were compared, both on safety merits and cost-effectiveness. The experience gained with this scenario-based approach will be used to establish a set of general requirements for safety assessment techniques in ship design. In the view that assessment results will be most probably presented in a quasi-quantified manner, the requirements are concerned with uniformity of both the safety assessment. These requirements make it possible that valid comparison between various assessment studies can be made. Safety assessment, founded on these requirements, provides a validated and helpful source of data during the coming years, and provides naval architects and engineers with tools experience and data for safety assessment procedures in ship design. However a lot of effort has to be spent in order to make the methods applicable in day-to-day practice.

In Korea, playgrounds have been developed quantitatively and qualitatively. However, there is a lack of interest in the play needs of children with disabilities. With this in mind, this study is concerned about the planning and design process of the inclusive playground constructed in 2016 at Seoul Children's Grand Park. The case study covered the Kkumtle Kkumtle playground in Seoul Children's Grand Park and was completed in December 2015. This playground is the first case of an inclusive playground ever built in Korea. The concept of the inclusive playground established in this study is: (1) a playground where not only children with disabilities but both children with disabilities and children without disabilities can play together; (2) a playground for both children with disabilities accompanied by their families and children without disabilities accompanied by family members with disabilities; (3) a playground that ensures universal accessibility to the entire space including play facilities; and (4) a playground where the most essential functions of a playground-fun, curiosity, and adventure-are centered on various activities. In conclusion, we presented limitations and opinions for improvements to design and policy proposals for social expansion of inclusive playgrounds. There are three ways to overcome limitations in design. First, there is a need for an in-depth study of play characteristics by type of disabilities of children. Second, it is necessary to develop facilities suitable for the actual situation of Korea through various social experiments. Third, if the inclusive playground centered on facilities is presented in this study, then several types of integrated playgrounds should be implemented in the future.

The enforcement of volume-rate disposal system which has been resulted in reducing the household waste and increasing the amount of recycled contents is showing positive effects that are generating social and economic benefits, However due to the lack of user's perception about how to separate and dispose of recycling wastes, some problems are constantly raised, like food waste is disposed in the standard volume-rate garbage bag. By rearranging visual information printed on standard plastic garbage bags (SPGB), this study attempted to find ways to deliver the information regarding how to use them properly. In order to achieve this, from the perspective of visual information design, the study examined the cases of visual information printed on nine SPGB from domestic and overseas. Among these, this study conducted a survey on user's awareness of visual information printed on SPGB in three districts of Seoul, Korea. As a result, user-preferred items were identified. Based on the result, this study selected information to be printed on SPGB, established the hierarchical order of the selected information, and proposed a guideline for using SPGB with informative graphics; therefore, the effectiveness of information delivery was improved. In addition, this study also examined the external validity of the guideline by comparing a survey on user's awareness.

Fresh Kills is the largest landfill in the world located in the west side of Staten Island, New York. The landfill served as a storage area for New York City's trash for more than 50 years. After years of civilian and political pressure, state and local legislation decided its closure of landfill operation in Fresh Kills in March 2001. Soon after, Department of City Planning announced a Fresh Kills international design com-petition: 'Landfill to Landscape'. The winning entry was promised to be outline for the redevelopment of the 2,200 acre site which the size of three times Central Park. Forty-eight teams representing more than 200 offices from around world submitted proposals, from which six finalists that mostly led by landscape architects were selected. In December 2001, a jury of architects, landscape architects and city officials unanimously selected Field Operations as the winner. The plan, named Lifescape, visualizes the gradual 20-year transformation of the whole Staten Island into a 'natural lifestyle island' recognizing that Staten Island is home to coastal wetlands that shelter one of the most diverse ecosystems in the New York metropolitan area. It suggested that an ecologically reconstituted Fresh Kills could become the center of integrated parks and greenways system on the island otherwise fragmented. The project will be one of the largest and most ambitious undertakings in the metropolis in years developing a complex web of habitats and parklands on top of mountain of trash. This study tries to achieve two goals: One is to provide general explanations on the project, Lifescape, breaking down to its background, geographical context, design concepts and phased development plan. Another is to introduce the unique and innovative design approaches by Field Operations that are different from a conventional landscape architectural attitude. Since this project was well published through many magazines and newspapers, main focus will be upon aspects that differentiate this project from usual landscape projects. Conceptually Lifescape brought provocative notions on nature/culture relationship and the role of urban park as an active agency rather than just a green rest area. Also this project introduced pioneering graphics like plan collage, diagrammatic plan, phasing diagram and photo montage as vehicles conveying information, imagination and provocation. Witnessing the influence of the project gradually in the field of academic and practice in the States, this study is intended to become a constructive reference to similar landscape projects dealing with large and complex urban context in conjunction with restructure of contemporary city.

This study conducted nonlinear finite element analysis to figure out the influence of shear performance on the ${\beta}$ of girders with trapezoidal corrugated web. Through the experiment specimen, analysis model which is highly accurate was verified. Based on this, a parameter analysis was conducted on key variables affecting ${\beta}$. Proposed formulas of previous studies were analyzed using parameter analysis result. Eurocode was designed to be safer than other proposals. Only models that are included in the inelastic area, depending on the Moon's proposal, were satisfied the proposed formulas by Kim to enhance economic design.

The role and importance of VE have been enlarged since VE application was mandatory by law in public sector in March, 2000. Public organizations have widened the technological horizon through VE competitions and applied VE technique to private investment projects. Many studies have been carried out on function analysis and VE procedure. In practice it is common that clients make a decision one-sidedly on whether or not VE proposals are selected. The VE procedure itself is not smooth. This study gives some suggestions on VE appraisal procedure and criteria at the last phase on VE process in order to smooth the progress of VE. The results of this study can be used as a tool to improve efficiency in the management of VE.

Although it is widely accepted that the interaction -between masonry infill and structural members significantly affects the seismic response of reinforced concrete (RC) frames, this interaction is generally neglected in current design-oriented seismic analyses of structures. Moreover, the role of masonry infill is expected to be even more relevant in the case of existing frames designed only for gravitational loads, as infill walls can significantly modify both lateral strength and stiffness. However, the additional contribution to both strength and stiffness is often coupled to a modification of the global collapse mechanisms possibly resulting in brittle failure modes, generally related to irregular distributions of masonry walls throughout the frame. As a matter of principle, accurate modelling of masonry infill should be at least carried out by adopting nonlinear 2D elements. However, several practice-oriented proposals are currently available for modelling masonry infill through equivalent (nonlinear) strut elements. The present paper firstly outlines some of the well-established models currently available in the scientific literature for modelling infill panels in seismic analyses of RC frames. Then, a parametric analysis is carried out in order to demonstrate the consequences of considering such models in nonlinear static and dynamic analyses of existing RC structures. Two bay-frames with two-, three- and four-storeys are considered for performing nonlinear analyses aimed at investigating some critical aspects of modelling masonry infill and their effects on the structural response. Particularly, sensitivity analyses about specific parameters involved in the definition of the equivalent strut models, such as the constitutive force-displacement law of the panel, are proposed.

In order to bear a relationship between the devices in the IoT environment whereby the task of navigating the device and relationship should be preceded before. The new device transmits a search signal in order to find a device and a peripheral device that receives this will determine the distance information of the device and determines the intensity of the transmitted signal. M2M (Machine to Machine) method has been used in conventional sends the search signal to all of the peripheral devices in a single device, a peripheral device that is greater the search time becomes long, a problem that a loss of information, the more devices that are far there is. In this paper, a method to compensate for problems of existing methods of M2M devices and new shortening of the search time when the search for the peripheral device, an algorithm to reduce the information loss of time to send and receive signals from the navigation device and away proposals were discussed and used in the field.

Men's fashion has not much changed due to the pervasive patriarchy Because of the change of gender roll and attitude towards one's appearance and fashion, men began to express themselves with fashion in the late 90's. The purpose of this study is to categorize men's image and their fashion styles from Korean TV dramas to provide informations for predicting men's fashion trend in rapidly changing market. Through the analysis of three dramas with 30% or more of audience rating by all age groups from January to July, 2009, nine distinctive male images were selected and their styles were analyzed; silhouette, details, materials, color, accessories, and hair-style. The results are as follows: In the past holding neat and straight line silhouettes but today shows tight silhouette. In color and detail, the use of brilliant chromatic colors, use of hight saturation colors, big and brilliant pattern, ruffles, frills, beads, knitwear, mix matched new composed materials, and light materials are dominant. While short and simple shape of hair-styles were predominant in the past, now we see more varied hair length. Not only that, variety of perms and colors are showed on TV screens. Hence, the results show that a lot of radical change has happened in the men's fashion, and marketing propositions that reflects this change in men's fashion market are requested along with trendy emotional product development and coordination proposals, and finally calls for more multilateral study and market search of male consumers.
