This study evaluated the characteristics and sensibility of work clothes materials developed that took into account the work environment of major industrial settings, for which a selection was made according to spring/autumn use and winter use. The physical properties of the existing and test weaving of the work clothes materials were compared after the test weaving of work clothes materials through material design, which altered the yarn count, composition, weave and density of material. To evaluate sensibility of work clothes materials subjectively, seven ranks' semantic differential scale questions were developed with polar adjective pairs. The test weaving of work clothes materials showed improved performance (such as tensile strength, dimensional change, water vapor permeability, and color fastness) compared to the existing materials. The common factor analysis indicated that the explanatory power of the cumulative variance for the spring/autumn use and winter use was 71.19% and 69.53%, respectively.

This study collected powder extinguishers with 6-10 years of elapsed life from January 2012 to January 2017 in market, factory, and apartment areas to experiment with changes in fineness and to examine the characteristics of extinguishing power. First, in the case of ABC powder, 98.3 wt% of the 8-year market area and 98.6 wt% of the 10-year apartment complex were found to be inappropriate in the first, second, and third arithmetic average analysis of the powder extinguisher from 6 to 10 years. That is, the fine distribution and size of the powder extinguishing agent particles should be managed within an appropriate range. It is analyzed that the powder fire extinguisher may experience a change in the fineness of the powder depending on the external environment exposure, placement, management status, and age of use, resulting in a decrease in digestive power or inability to radiate. Second, the fire extinguisher cannot be used in the initial fire suppression depending on the place of deployment, the environment of deployment, the progress of the number of years of use, and maintenance, so it is necessary to strengthen the device that enables fire extinguisher maintenance and inspection. Third, in the manufacturing process, the charging method should also be reviewed in consideration of the conditions of the workplace, the humid season, and the rainy environment.

From designers' viewpoint, today, the major environmental change can be found in the digital environment. Especially, more than the development of physical product which can be characterized as the backup of old function and realization of new function in the field of product design, as the digital product development of program style that exists without substance is deepened, the development of the digital design media has been accelerating. However, it is the recent matter that the link with educational system about the added value which could be embodied by digitech, and the interdisciplinary research about producing goods become regular. The construction of the industrial design development process based on the digital environment must be the major research object. Therefore, the goal of my research is to present the concept of the product design process model required in the digital environment.

Man has always striven to create a thermally comfortable environment. This is reflected in building traditions around the world - from ancient history to present day. Today, creating a thermally comfortable environment is still one of the most important parameters to be considered when designing buildings. It is defined in the ISO 7730 standard as being "That condition of mind which expresses satisfaction with the thermal environment". A definition most people can agree on, but also a definition is not easily converted into physical parameters. Thermal comfort is a matter of many physical parameters, and not just one, as for example the air temperature that is set by air-conditioner. The most important matter Today's common offices and homes are only depending on air-conditioning as a cooling system during the summer. This kind of system tends to be focused on the person who controls it and those who are around the air-conditioner while thermal-comfort is neglected. Futhermore, the people's body conditions are not considered during each time that beginning, middle, last of the air-conditioning which causing displeasure of the residents more and more. This kind of operating system is set for a long time may causes unbalanced air condition and man's psychologic displeasure goes to increase.

The Antarctic continent exposed to strong wind, very low temperature, and extremely dry condition. The freezing-thawing cycles under this extreme environment change the mechanical characteristics of rocks near the ground surface. To investigate the effect of freezing-thawing cycles under the extreme environment understand on geotechnical properties of rocks, rocks from the Antarctica were collected from two places: (1) West Antarctic Cape Burks and (2) East Antarctic Terra Nova Bay areas. The rock characteristics of these two areas were described and compared. For Terra Nova Bay area, rock characteristics of rocks near the surface and depths exceeding 2.9 m were examined. The 'near-the-surface rocks' averages of absorption rate, P-wave velocity, and unconfined compressive strength were 0.56%, 3,717 m/s, and 109MPa, respectively; while, those values of 'deep-sited rocks' were 0.24%, 4,670 m/s, and 88MPa. From the measurements, it was found that the effects of weathering were not significant on mechanical characteristics (strength) but were pronounced on physical characteristics(absorption and P-wave velocity).

Our natural desire to exuviate old theory and search for new ideas means conversion and reformation. Howev-er, the new idea of the present moment will soon become an ancient history when the next generation emerges with more advanced ideas. Naturally, we have learned to accept the past history and utilized it as a the foundation for the future. Through the repeated process of the learning method, the popula-tion cultivate themselves with proper understanding and appropriate attitude toward design. By analyzing social behaviors of the past and living conditions, we can ex-pand our imaginations beyond limits. Each society and its local condition have tremendous effects on the develop-ment and progress of artistic theories, techniques and craftsmanship, and potential design of every day use products. Today, interior design can not afford to ignore the or-ganic relationship of life style and space. Thus, the plan-ning of space means the planning of life style. Life style, as it is, has a vast definition and changes with time. That is why spaces, which consider the life style and its environment when designed, show different aspects ac-cording to its corresponding time. Interior design, in particular, differs by time and re-gion to create its unique style. The change in space is the natural result of the change in life style which again is sensitive to the change in cultural and environmental elements. Design is no longer designing of mere physical elements and environment. Design should be taken as the equivalent of creating spiritual culture.

The purpose of this study is to grasp the change of modern space concept and analyze how to adopt and embody the change in modern fashion. The study researched wearer's costume space and analyzed space shown in supermodern fashion design by classifying it into response to non-space, allowance of wearer-based space, scientific space of architectural skill and embodiment of space image. As a study method, literature and study material of sociology, anthropology, fashion sociology and design field were referred. For picture data of supermodern fashion work, specialized book, designer, brand collection material and internet site pictures were collected and analyzed. The study result shows the following features of fashion design space embodiment corresponding to the change of supermodern environment. First, supermodern design secures closet space like pocket for portable objects and uses design space in order to provide the space for convenience of movement. Second, supermodern design creates wearer-based independent space in order to secure person's physical and mental stability in city environment. Third, supermodern design uses space scientifically from the aspect of detail and shape by applying space of architectural skill to space. Fourth, supermodern design shows aesthetic feature that embodies interpretation of space by conceptualizing space image and using fashion.

Purpose: This study was intended to discover the effect of the turning training on figure of 8 tract on stroke patients' static and dynamic balance, as well as walking. Methods: A total of 42 stroke patients participated in this study. The training group was trained on the figure of 8 tract, while the control group was trained on the straight path for 30 minutes per day, for 4 weeks. Berg balance scale was used to measure the balance of the patients, before and after the training, and Good balance system was used to measure the sway speed and the distance of COG while standing. To measure the ability of walking, TUG and FSST were also used. Results: There were significant increases in the average score of Berg balance scale, in both groups after the training, and also significant difference between both groups were observed. The training group showed significant differences in the static balance ability, as well as anteroposterior and mediolateral sway speed. Further, there were significant increases in the dynamic balance ability, COP total distance, and TUG in both groups. The results showed more differences in comparing the control group with that of the training group. In FSST, there was no change in the control group, but there was a significant increase in the training group. Conclusion: Turning training on figure of 8 tract in stroke patients significantly increased the static and dynamic balance and walking ability. Based on the results, it can be seen that the training on the figure of 8 tract can influence the ability of balance and walking, which can lead to appropriate reactions to the change of environment and various tasks. Thus, it is assumed that turning training on figure of 8 tract as a means of improving the condition of stroke patients can be a meaningful program.
