This study focuses on how clothing can increase in the age of the shared economy and as an alternative to the capitalist economy of the 21st century. This study investigates how infants and children use clothes as they undergo many changes based on physical growth, identifies use and disposal methods for surplus clothing from the perspective of a shared economy and explores plans to foster an environment for the healthy use of clothes. The objectives of this study are as follows. First, identify the need for new clothes based on physical changes in the human body; second, propose an alternative to permanent disposal by making used clothes appropriate for temporary disposal (renting and leasing). In sharing services, the condition and quality of the product were found to be the most important factors. The condition and quality of the product (70.0%) were the most important factors in sharing services. The sharing services for clothes and goods of infants and children could become popular quickly if there was a reliability guarantee offered by such sharing services. In addition, providing trial services and aggressive publicity for sharing services is urgent for the expansion of opportunities for general consumers.

Purpose: The main objective of this paper is to propose an RD method by developing a neural network (NN)-based estimation approach in order to provide an alternative aspect of response surface methodology (RSM). Methods: A specific modeling procedure for integrating NN principles into response function estimations is identified in order to estimate functional relationships between input factors and output responses. Finally, a comparative study based on simulation is performed as verification purposes. Results: This simulation study demonstrates that the proposed NN-based RD method provides better optimal solutions than RSM. Conclusion: The proposed NN-based RD approach can be a potential alternative method to utilize many RD problems in competitive manufacturing nowadays.

The Purpose of this study is to analyze the mechanism of permanent death and playing aspects in Rogue-like games. The death in digital game is not only punishment of failure, but reward for player's growth. However the mechanism of permanent death which does not allow to resurrect is critical penalty for players and causes play-cycle with high anxiety. In the mechanism of permanent death, players do critical play to evade the death. But when they replay the game they modify their unethical choices to build alternative game world. Through the mechanism of permanent death which demands critical and alternative play, it could be possible to find the way to design games with serious choice.

The imbalance of energy demand and supply caused by rapid industrialization around the world and the associated environmental issues require and alternative energy source with possible renewable fuels. Political instability and depletion of cruel oils are other factors that cause fluctuation of oil price. Securing a new alternative energy source for the next century became an urgent issue that our nation is confronting with. As a matter of fact, the fuel cell technology can be widely used as next generation energy regardless of regions and climate. Specially, the ability of expansion and quick installation enable one to apply it for distributed power, where the technology is already gaining remarkable attentions for the application. Particularly, leading industrialized nations are focusing on the PEM fuel dell with anticipation that this technology will find their place of applications in the vehicles and homes. In this study, demonstrate the multi physics modeling of a proton exchange membrane(PEM) fuel cell with interdigitated flow field design. The model uses current balances, mass balance(Maxwell-Stefan diffusion for reactant, water and nitrogen gas) and momentum balance(gas flow) to simulate the PEM fuel cell behavior.

The supercritical $CO_2$ Brayton cycle energy conversion system is presented as a promising alternative to the present Rankine cycle. The principal advantage of the S-$CO_2$ gas is a good efficiency at a modest temperature and a compact size of its components. The S-$CO_2$ Brayton cycle coupled to a SFR also excludes the possibilities of a SWR (Sodium-Water Reaction) which is a major safety-related event, so that the safety of a SFR can be improved. KAERI is conducting a feasibility study for the supercritical carbon dioxide (S-$CO_2$) Brayton cycle power conversion system coupled to KALIMER(Korea Advanced LIquid MEtal Reactor). The purpose of this research is to develop S-$CO_2$ Brayton cycle energy conversion systems and evaluate their performance when they are coupled to advanced nuclear reactor concepts of the type under investigation in the Generation IV Nuclear Energy Systems. This paper contains the research overview of the S-$CO_2$ Brayton cycle coupled to KALIMER-600 as an alternative energy conversion system.

R407C is considered as an alternative refrigerant to R22 for air conditioners. An experimental investigation was made to study the characteristics of the condensation heat transfer and pressure drop for R407C flowing in a fin-and-tube heat exchanger used for commercial air-conditioning units. Experiments were carried out under the conditions of inlet refrigerant temperature of 6$0^{\circ}C$ and refrigerant mass flux varying from 150 to 250 kg/$m^2$s for refrigerant side. The inlet air has dry bulb temperature of 35$^{\circ}C$ , relative humidity of 50% and air velocity varying from 0.8 to 1.6 m/s. Experiments show that air velocity increased by 25% is needed for R407C than that of R22 for subcooling temperature of 5$^{\circ}C$, which resulted in air-side pressure drop increase of 28.8% for R407C as compared to R22. As a consequence, in order to provide the same design condition of a condenser, the fan requires higher electric-power consumption with R407C than that with R22.

The application of composites as an alternative material for marine steel hatch covers is the subject of this study. Two separate approaches are considered; weight reduction approach and strengthening approach. For both approaches Finite Element Analysis (FEA) was performed using ANSYS software. Critical design parameters of the composite hatch cover and FEA are discussed in details. Regarding the weight reduction approach; steel hatch covers of a bulk carrier were replaced by composite covers and a weight reduction of 44.32% was achieved leading to many benefits including fuel saving, Deadweight Increment and lower center of gravity of the vessel. For the strengthening approach; the foremost hatch cover was strengthened to withstand 150% of the load required by IACS for safer navigation while no change in weight was made between the steel and composite covers. Results show that both approaches are feasible and advantageous.

The purpose of this research is to provide basic data for the promotion strategy to activate modular construction system as residential facilities, through a study on the architectural planning, institutions and policies and research on connection details, for the use as residential facilities of the modular construction that is not actively supplied for the general residential facilities. As a result, I suggest sample model plan of domestic and foreign case analysis and characteristic of modular construction and practical application of modular construction for Residential Facilities. Owing to many advantages including short construction period structural stability and economic benefits, modular construction is expected to play a role as residential alternative of socially controversial affordable housing and weekend homes, and potential housing shortage after reunification; and to contribute to the development of design automation and industrialized constructions. Though Korea is still lacking development of the system that meets the domestic context, if supported by ongoing researches on the development of construction methods, materials and details, the settlement of appropriate modular residential facilities to suit the national situation will serve a possible alternative solution for many housing and environmental problems.
