Recently, the demand for marine leisure industry is rapidly increasing due to the five-day work week and the per capita income approaching US $ 30,000. In particular, the Republic of Korea is surrounded by the sea on three sides and is composed of 3,150 islands and coastline. As shipbuilding infrastructure is abundant and the government is expected to actively support policies as a new growth engine, leisure boat furniture industry is expected to grow rapidly along with leisure boat manufacturing. Therefore, in this paper, after understanding the leisure boat (yacht) and analyzing the requirements of yacht furniture, we proposed a beautiful yacht furniture design that is lightweight, durable and safe using a 120-foot super yacht that can best show the characteristics of yacht furniture using wood bending technology and color variation of woods.

In this paper we consider a design problem of a cyclic queueing network with two stages, each with a local buffer of limited capacity. Based on the theory of reversibility and product-form solution, we derive the throughput function of the network as a key performance measure to maximize. Two cases are considered. In case each stage consists of a single server, an optimal allocation policy of a given buffer capacity and work load between stages as well as the optimal number of customers is identified by exploiting the properties of the throughput function. In case each stage consists of multiple servers, the optimal policy developed for the single server case doesn't hold any more and an algorithm is developed to allocate with a small number of computations a given number of servers, buffer capacity as well as total work load and the total number of customers. The differences of the optimal policies between two cases and the implications of the results are also discussed. The results can be applied to support the design of certain manufacturing and computer/communication systems.

In this paper, we use scratch to design and develop non-formal learning experiences that are linked with contents of secondary science textbook to educational programs. The goal of this paper is to develop a convenient and interesting program for non-formal learning in a learning environment using various smart device. Theoretical approaches to mobile education, such as smartphones, and smart education support policies continue to lead to various research efforts. Although most of the smart education systems developed for students who have difficulty in academic performance are utilized, they are limited to general students. To solve the problem, the learning environment was implanted by combining the scratch, which is an educational programming that can be easily written. The science education program proposed in this paper shows the result of process of programming using ICT device using scratch programming. In the evaluation stage, we were able to display the creations and evaluate each other, so that we could refine them more by sharing the completed ideas.

End-to-end congestion control mechanism have been critical to the robustness and stability of the Internet. Most of today's Internet traffic is TCP, and we expect this to remain so in the future. TCP/IP is the intermediate transport layer candidate for today's applications. TCP uses an adaptive window-based flow control. The congestion avoidance and control algorithms deployed by TCP aims at using the available network bandwidth. This paper compares different congestion control policies, and proposes the new design mechanism for future public networks

As children are known to touch and chew everything, green cleaning procedures are an important step in preventing children from ingesting harmful toxins. The objectives of this study are to develop a new, self-evaluation checklist and to suggest design recommendations which comply with easy, adaptable, economical ways to improve the eco-friendly indoor environment of Korean childcare facilities. The information compiled during this study was collected through literature review and internet surveys1) from July, 2009 to February, 2010. The results of this study show that the current Korean childcare accreditation system and practices emphasize clean building interiors, policies for sanitation and cleanliness, and control of humidity and lighting. On the other hand, the information provided by green-building rating systems from GBCC, LEED, and GBTool offers additional and comparative details regarding indoor environment quality and standards regarding the IAQ performance and management plan, ventilation and thermal comfort systems, views from windows, acoustics, and lighting. In conclusion, this document provides an appropriate and easy-to-follow, self-evaluation checklist composed of eight criteria and 51 practical items. This study also provides the design recommendations composed of 27 practical ideas focusing on interior elements. Both the checklist and design recommendations I have suggested can be a post-occupancy tool for evaluating eco-healthy facility standards as well as tips for continuing to maintain eco-healthy childcare facilities.

This work aims on the one hand at the sublation of the typical image of the existing travel agencies and on the other at the making of new image that meets the clients' wishes. Looking in the face that in the existing travel agencies most clients are straying with the overflowing and selling-oriented informations, this design work pursue the image making of a new atmosphere of travel agency, in which the clients can make a rational choice. In complying with the policies of the travel agency in the Karstadt department store I have arrived at the basic design theme: the desire for travel depends on how organically and reciprocally the interest on the travel and the presentation of the travel information are combined with and permeated into each other, and furthermore how multifariously and plentifully these reciprocal combining and permeating are put on the stage. So it follows that the travel agency must let the clients indirectly experience the wished travel through staging various kinds of experience spaces. Consequentially the basic concept of the design can be summarized in the following: overlapping-transmitting and permeating-suspending.
