Appearance management is evolving as a means of self-expression or as a way of expressing one's individuality. In particular, hairstyle is the most important part of a person's appearance and accounts for 70% of the appearance. Improving people's appearance by changing their hairstyle gives them confidence. Among them, the fringe hair style plays an important role in determining the first impression and reflects the trend. Fringe is shorter and simpler than general hair treatment, but even these small treatments have the effect of changing the impression, so women are trying to transform into a fringe hair style. A previous study was conducted on four lines classified: round, heart, square, and triangular. In this study, we added them to define 5 hairlines and created them by combining each hairline. that have been produced 5 fringe hair styles that suit the shape of the face. It is expected that the results of this study will be used as educational materials for hair line and fringe hair styles in the field, contributing to the beauty industry.

A Container terminal is a physical link between the ocean and land modes of transport and a major component of the container physical distribution system. A number of projects to increase terminal productivity in the world were found to be tied directly to increasing the efficiency of the intermodal activities, that is, to improving the physical distribution process. This is an indication that the productivity of container terminal is being considered withing a system prospective. The purpose of this study is to establish a model of the container physical distribution system for Pusan port linked with 4 sub-systems including Navigational aids system, Cargo handling/transfer/storage system on dock, Off-dock CY system and In-land transport connection system. and to analyze the system. From this analysis, we found that the system had three bottlenecks on the container physical distribution process in Pusan port : a) cargo handling b) storage and c) inland transport, and showed a way to improve the system.

Smart home in the 4th industrial revolution environment is where all devices in the home are connected to each other to provide the optimal living environment desired by the user. Artificial intelligence speakers are being used as a way to manage and control all devices used in this environment. The function of an artificial intelligence speaker ranges from simple music playback to serving as an interface that controls and manages all devices in a smart home space. In this study, we investigated and analyzed the usability of artificial intelligence speakers based on the current status of domestic and overseas markets and the survey contents of two organizations (Korea Consumer Agency and Korea Information and Communication Policy Institute (KISDI)). In addition, we investigated and analyzed the usability of artificial intelligence speakers. Based on the results of responses from users from two related organizations, major problems were derived, and major improvement measures, such as discovering new functions and improving voice recognition performance, were also described.

Tangible user interfaces have attracted strong attention in the HCI(Human and Computer Interface) community for their ability to take advantage of skills humans develop in the real world. We are developing "tangible media aided design system" which employs physical objects i.e., brick as interfacing media for 3D graphic modeling. This system is targeting for persons who are afraid of experiencing 3D graphic modeling and virtual space, or have a sense of reluctance in approaching to them. Our approach suggests the easiest way for people to experience computer system and virtual space carefree while developing and improving their space sense. This work is one of initial explorations of media aided design system using tangible user interfaces.

The current three-stage cold farming process to produce a flange is investigated for the purpose of improvement of manufacturing process. The main goal of this study is to obtain an appropriate process sequence, which can produce the required part with less manufacturing cost. The current process sequence is simulated using finite element method and design criteria are examined. Based on the results of simulation of the current three-stage process. a design strategy for improving the process sequence is analyzed using the thick-walled pipes. Because it has a reduced process-sequence without buckling of the workpiece or overloading of tools, the new process has distinct advantages over the conventional process. Numerical results show that the newly proposed process with selected presses is the most economical way to produce the required part.

Strengthening as well as correcting unsightly deflections of reinforced concrete (RC) beam may be accomplished by retrofitting. An innovative way to do this retrofitting that is proposed in this study utilizes turnbuckle to apply external post-tensioning. This Turnbuckle External Post-Tensioning (T-EPT) was experimentally proven to improve the serviceability and load carrying capacity of reinforced concrete beams. The T-EPT system comprises a braced steel frame and a turnbuckle mechanism to provide the prestressing force. To further develop the T-EPT, this research aims to develop a numerical scheme to analyze the structural performance of reinforced concrete beams with this kind of retrofitting. The fiber method analysis was used as the numerical scheme. The fiber method is a simplified finite element method that is used in this study to predict the elastic and inelastic behavior of a reinforced concrete beam. With this, parametric study was conducted so that the effective setup of doing the T-EPT retrofitting may be determined. Different T-EPT configurations were investigated and their effectiveness evaluated. Overall, the T-EPT was effective in improving the serviceability condition and load carrying capacity of reinforced concrete beam.

This paper overviews the concept of the strategic niche management, which emphasises the social aspects of new technologies and calls for relevant government policies for socio-technical transition. Hydrogen energy technologies remain in the niche level, thus the SNM perspective is appropriate to be applied. The reason why, and the way how to see hydrogen as a socio-technical niche are discussed, followed by an analytic argument on hydrogen policies and their SNM characteristics. Final part of the paper deals the design of the socio-technical experiment. It is expected that this paper would contribute to not only policy development but also improving understandings on the socio-technical nature of hydrogen energy of hydrogen community.
