While institutional matters such as improvement on Basic Guidelines for Construction Safety are greatly concerned to reduce falling accidents at construction sites, there are short of studies on how to practically predict accident signs at construction sites and to preemptively prevent them. As one of existing accident prevention methods, it was attempted to build the early warning system based on standardized accident scenarios to control the situations. However, the investment cost was too high depending on the site situation, and it did not help construction workers directly since it was developed to mainly provide support operational work support to safety managers. In the long run, it would be possible to develop the augmented reality based accident prevention method from the worker perspective by extracting product information from BIM, visually rendering it along with site installation materials term and comparing it with the site situation. However, to make this method effective, the BIM model should be implemented first and the technology that can promptly process site situations should be introduced. Accordingly, it is necessary to identify risk signs through lightweight image processing to promptly respond only with currently available resources. In this study, it was intended to propose the system concept that identified potential risk factors of falling accidents by histogram equalization, which was known as the fastest image processing method presently, used visual words, which could enhance model classification by wording image records, to determine the risk factors and notified them to the work manager.

The following study from the perspective that the identity of a brand is determined by the creative work of the designer, will review the design identity of fashion house, which have maintained a basic concept of couture house until recently. For this purpose, first, the concepts of fashion house and identity could be examined, and then the design identity of both the past couture designer and the present house designer could be comparatively analyzed. This study focused on John Galliano of Dior, and was carried out under the method of document study and case study. Based on this, the analytic results of the design identity of fashion houses are as follows. The design identity of fashion house, which has its origins in the past couture house, appears from the house characteristics, design characteristics and the design image. The original design identity of Dior House seems to be feminism and elegant extravagance, which naturally models the body line of women into diverse lines. The new design identity of Dior House by Galliano, while reflecting wit and fantasy, at the same time is expressed as sexy and romantic elegance which attempts to express the beauty of modern women. The pursue of chic elegance, which is the characteristic of early Dior design, have changed into avant garde and unique designs with tendencies of multi-culturalism due to the most recent house designers. Finally, Dior house design has successfully maintained the master of handcrafted quality based on craftsmanship, the history from the house archive, and the modern trends appropriately added by the creativity of Galliano.

On the general trends of weight control for slimness, this study surveyed and compared eating attitude influenced by eating disorder, eating habits, and nutrition knowledge by obesity index in middle school girls. The purpose of this study was to investigate the eating disorders and eating habits, and analyzed these data by degree of obesity. This will provide basic information of nutrition education for adolescents who need to have proper body shape and dieting habits. This survey was conducted to one of girls' middle school in Incheon and all the data was analysed by SAS(Statistical Analysis System) program. The average height, weight and PIBW were 158.7cm, 48.2kg, and 93.9% in students. However, 50.8% of students were underweight or severely underweight. Most of female students perceived that they were normal or overweight even though they had underweight or normal. There was a significant difference in experience and intention of weight control by degree of obesity. In the overweight group, EAT-26 score tendency was high, especially preoccupation with losing weight(factor 1). It shows that obesity index had meaningful correlation with EAT-26 score and factor1. In dietary habit, overweight group showed more irregular meals tendency, and overeat frequently. On the other hand, this group had lower frequency and of smaller amount snacks. The intake frequency of meals and snacks showed in the affirmative way regardless of degree of obesity. The average score for nutrition knowledge about calorie and weight control was low. Correct answer rates were increased in higher overweight group. In conclusion, teenage girls who concerned too much about their slim body image need to be educated about accuracy concept of the body image. Also, practical and systematic nutrition education should be done for the correct nutrition knowledge and its application ability of individuals.

The present age is requested designer to be a generalist. The educational methods of university is changing over from intention of the technical education which is one of the traditional education methods to intention of a talented man with multiple knowledge. Also, the universities are establishing special curricular for cultivating men of ability. Many of an employer want to engage not only the specialist as the talented men in their own major field, but the generalist as the multiple knowledge in several field. Designer should have both a good stock of knowledge and personality. Also design should be able to easy access to all as a generalist instead of an obstinate streak as a monopoly of their specialist. This study was focused on development of basic research for understanding about design to generalist. It is purposed to suggest a research for a new recognition of design.

This research has a significant meaning to observe and understand the historical condition of a furniture industry and the characteristics of Korean home furniture's formation, ability, skill and materials from 1980s when there were an economic growth and a historical development of Korean home furniture occurred to present days. During 1980s, there was an automatic system available and has enforced and settled the standards on its quality and price in a furniture industry. Also, there was a big trend of black furniture as well as an entrance of corporation and high glossy furniture due to technical cooperation from Europe. In 1990s, there was an entrance of furniture which various techniques was applied due to a high development of the materials and skills, and also various sizes of height and weight and enlargement of acceptance function using highly-technological hardware. After 2000 and now, pro-environmental products is embossed in the Korean home furniture where they added a public issue which is the concept of well being, and A.I and sub material has been pro-environment. There also was a natural unity between nature and technology because of increased usage of trees with its natural patterns, metals, and glasses. For the future development of home furniture design, This problem should be promptly recognized that current home furniture designs are now on the verge of being lack of originality and are just following the market demand and recent trend as it is. Then, there should be a development of its specialized, detailed, unique design as well as a development of advanced materials, production management, distribution, and so on, and carrying out a diversified research continuously. There also should be a systematic education, which is necessary for training specialists to lead the Korean home furniture design industry as well as preparing a basic level for the future without a negligence.

We need to seek after new direction and order of design that puts more value on the spirits and culture of human beings in the 21st century, creating a new, all-inclusive value in which individual human being, the society and the environment can co-exist in a peaceful relationship by overcoming the materialistic, analytical, competitive, and differentiated values of traditional industrial society. The aim of this study, then, is to present a new method of design that can meet the demands of the 21st century in a civic age of information, knowledge and culture, by focusing on Monistic ideals derived from a deeply rooted Oriental philosophy. The concept of Monism is embodied by a mind set that treasures the benefit to others over rewards to the self, puts more importance on the spiritual life hidden behind physical phenomena, thinks more of what lacks than what exceeds, elevates the mind over the body, and seeks after beauty via a total harmony of balance and development that can be feasible only by combining all these elements. Ultimately, the new design principle based on the Monism consists of three basic elements: (1) identification of the subject and the object between things under the perception that all things are one (Unification); (2) the ability that helps things exist with appropriate beauty maintaining balance and stability (Harmony); and (3) the attitude of sharing to maintain sustainable vitality by filling up what lacks or is missing in a whole(Change).

Decomposed granite soils are in a wide range of conditions depending on the degrees of weathering. This paper is intended to examine laboratory tests such as consolidation tests and conventional triaxial compression tests conducted in order to find out the mechanical properties of Cheongju granite soil. Along with the foregoing, the results of basic physical tests conducted in order to grasp the physical properties of Cheongju granite soil were described and based on the results, methods to calculate the mechanical parameters of numerical approaches using Lade's double surface work-hardening constitutive model were examined. Finally, it is intended to explain the stress properties of Cheongju granite soil used as a geotechnical material based on its shear behavior and critical state concept using the results of isotropic consolidation tests and triaxial compression tests. As a conclusion, it can be seen that in the relationship between confining stress and maximum deviator stress, the slope is maintained at a constant value of 2.95. In the drained CTC test, maximum deviator stress generally existed in a range of axial strain of 6~8% and larger dilatancy phenomena appeared when confining stress was smaller. Finally, based on the results of the CTC tests on Cheongju granite soil, although axial strain, deviator stress and pore water pressure showed mechanical properties similar to those of overconsolidated soil, Cheongju granite soil showed behavior similar to that of normally consolidated soil in terms of volumetric strain.

In this study, we developed and applied 15 evaluation questions about light to 30 middle school students in K University Science Education Institute for the Gifted. Then we used the theory of knowledge space and analyzed the middle school Science Gifted Students' knowledge state about light. By schematizing the hierarchy from it, we intended to not only measure students' knowledge state about light, but use it as the basic materials to improve teaching methods. To achieve the purpose of this study, we analyzed the evaluation results and individual knowledge state and hierarchy of questions. As a result, there were different knowledge structures in the individual, and we found that we should diagnose them differently. In addition, we have had implications that it has the connection with each questions and the individual knowledge state.
