Various approaches directly using vibrations of speakers have been suggested to effectively display the aural information such as the music to the hearing-impaired or the deaf. However, in these approaches, the human can't sense the frequency information over the maximum perceivable vibro-tactile frequency (around 1kHz). Therefore, in this study, an approach via spectral modulation of compressing the high frequency audio information into perceivable vibro-tactile frequency domain and outputting the modulated signals through the designated speakers is proposed. Then it is shown, through simulations of using Short-Time Fourier Transform (STFT) with Hanning windows and through preliminary experiments of using the vibro-tactile display testbed which is built and interfaced with a notebook PC, that the modulated signal of a natural sound composing sounds of a frog, a bird, and a water stream could produce the noise-free signal suitable enough for vibro-tactile speakers without causing Significant interfering disturbances, Lastly, for three different combinations of information provided to the subject, that is, i) with only video image, ii) with video image along with the modulated vibro-tactile stimuli as proposed in this study to the forearm of the subject, and iii) with video image along with full audio information, the effects to the human sense of reality and his emotion to given audio-video clips including various sounds and images are investigated and compared. It is shown from results of those experiments that the proposed method of providing modulated vibro-tactile stimuli along with the video images to the human has very high feasibility to transmit pseudo-aural sense to the human.

The purpose of this research is to obtain and analyze dynamic responses from human volunteers for the development of the human-like mechanical or mathematical model for Korean males in automotive rear collisions. This paper focused on the introduction to a low-speed rear impact sled test involving Korean male subjects, and the accumulation of the motion of head and neck. A total of 50 dynamic rear impact sled tests were performed with 50 human volunteers, who are 30-50 year-old males. Each subject can be involved in only one case to prevent any injury in which he was exposed to the impulse that was equivalent to a low-speed rear-end collision of cars at 5-8 km/h for change of velocity, so called, ${\Delta}V$. All subjects were examined by an orthopedist to qualify for the test through the medical check-up of their necks and low backs prior to the test. The impact device is the pendulum type, tuned to simulate the crash pulse of a real vehicle. All motions and impulses were captured and measured by motion capture systems and pressure sensors on the seat. Dynamic responses of head and T1 were analyzed in two cases(5 km/h, 8 km/h) to compare with the results in the previous studies. After the experiments, human subjects were examined to check up any change in the post medical analysis. As a result, there was no change in MRI and no injury reported. Six subjects experienced a minor stiffness on their back for no more than 2 days and got back to normal without any medical treatment.

The decision-making by agents in games is commonly based on reinforcement learning. To improve the quality of agents, it is necessary to solve the problems of the time and state space that are required for learning. Such problems can be solved by Macro-Actions, which are defined and executed by a sequence of primitive actions. In this line of research, the learning time is reduced by cutting down the number of policy decisions by agents. Macro-Actions were originally defined as combinations of the same primitive actions. Based on studies that showed the generation of Macro-Actions by learning, Macro-Actions are now thought to consist of diverse kinds of primitive actions. However an enormous amount of learning time and state space are required to generate Macro-Actions. To resolve these issues, we can apply insights from studies on the learning of tasks through Programming by Demonstration (PbD) to generate Macro-Actions that reduce the learning time and state space. In this paper, we propose a method to define and execute Macro-Actions. Macro-Actions are learned from a human subject via PbD and a policy is learned by reinforcement learning. In an experiment, the proposed method was applied to a car simulation to verify the scalability of the proposed method. Data was collected from the driving control of a human subject, and then the Macro-Actions that are required for running a car were generated. Furthermore, the policy that is necessary for driving on a track was learned. The acquisition of Macro-Actions by PbD reduced the driving time by about 16% compared to the case in which Macro-Actions were directly defined by a human subject. In addition, the learning time was also reduced by a faster convergence of the optimum policies.

The recognition of the environment and its importance have generated various types of parks, such as the ecological put the environmental put and the natural academy. They are considered the connecting media for the creation of space as a new paradigm in design for the 21st century from the late 1990s, environmental designs in space planning have been created from various angles of Perspectives including restoration of the natural ecosystem and introduction of natural circulation systems. Based on the aye facts and through theoretical examination of environmental park models, this research (1) establishes the concept and the significance of environmental parte; and, based on this, classifies the types of industrial sublimity; (2) presents environmental designing principles and standards; and (3) presents the "Chung Ra pro-Environmental Park plan" based on these ideas. The following is the summary of research results: First, while existing city parks are human-oriented, interior-oriented, and shape-centered, an environmental park considers human and nature equally and gives great importance to the relationship between the internal and external of the subject. It is a mark of environmental education that considers the natural ecosystem. Therefore, the environmental park is the 21st Century′s type of an open park for creating new forms of nature, as well as for incorporating culture and values through education. In such an environmental system, nature, culture, and human beings pursue balance, harmony, and security through mutual recognition. Second, in a broad sense, the types of environmental park can be classified into Cultural Restoration, Ecological Conservation, and Environmental Replacement. Third, by selecting Chung na environmental park in Incheon, which is a filtration plant lot, as a research subject, I have presented alternative planning for environmental parte in which culture and nature coexist on the basis of environmental planning principles and standards.

This study investigated how the contents of biology domains that were dealt with in the 7th national elementary-school science curriculum were in turn dealt with in the other subject matter areas. Through this, it was hoped that the place and identity of biology as a subject could be more clearly established and defined and additionally, more basic data for developing the new national science curriculum could be acquired at the same time. Subject matter areas that overlapped with biology in the 7th national elementary-school curriculum were practical arts, social studies and physical education. The structure and composition of specific components that were dealt with by these subject matter areas were very different from those of science, and the analysis showed that they failed to correspond across grades. Moreover, topics such as 'natural calamities and the environment' and 'human reproduction' that were dealt with by other subject matter areas, but not in science must be included for developing the new national science curriculum. Accordingly, when it comes to composing the contents of each subject matter area during creation of the new national curriculum, the relevant experts in related subject matter areas should be mobilized to conduct in-depth analysis of the following areas: viability, the most appropriate level of difficulty, and appropriateness of any hierarchy of relative importance between subjects. Additionally, efforts to reflect any improvements in the way the new national curriculum is developed which come about through this research are needed.

The purpose of this research was to assess the trends in research and curriculum of college education program in fashion marketing, and to suggest the implications for the research and education of fashion marketing business. The data extracted from the articles published in JKSC/IJCF and the college education curricula from 2006 to 2015 were examined to compare the result with the trend for the last 30 years of JKSC/IJCF research trend and education curricular based on the previous research. The results indicated that more than 70% of research was focused on consumer- oriented subject, such as consumer decision making process and consumer behavior, while more than 70% of education program was directed on firm-oriented subject, such as merchandising and marketing management. These results implied a slight shift for the academic research from consumer to firm oriented when comparing the result with the last 30 years of data, although the education was reclined conversely. The academic research and education program should be related in order to provide fashion industries with well educated human resources.
