The attempt of the contemporary society to overcome the environmental crisis is considered what the whole world is currently interested in. Since value of resources recycling has become emphasized even more, the field of design is, now, working hard to prove how much they are passionate about this eco-friendly design. Of all those activities that the field of design is involving in, a concept called 'upcycling' is receiving the greatest spotlight as a new trend. When it comes to upcycling, you should understand it as a both functional and aesthetic upgraded idea of conventional 'recycling' which would re-use waste resources. With this upcycling, you will have a chance to re-create an object of a new value, and it is a design concept which would consider environmental aspects but also social aspects. Since the year of 2000, the field of furniture design has been pursuing a new design trend which would intensively concern this upcycling concept. In the light of the present circumstances described on the above, this study conducts a case analysis on how upcycling of different materials is applied to furniture design since the year 2000. In doing so, the study improve understanding on furniture design as proposing new ways for you to look at the concerned design. Not only that, it also comes up with ideas and directions for new upcycling furniture design which could be demanded by the environmental industry.

This study introduced food waste into re-vegetation base materials for surface loss recovery of carry-away highway cut slope. The object of this study is to derive the mixing ratio of food waste by conducting a test installation, monitoring, analysis and evaluation for recovery of carry-away highway cut slope. The following items were investigated and analyzed each experimental zone to draw mixing ratio of re-vegetation base materials and food waste : the physical and chemical properties of the vegetation base materials, soil-hardness, soil-humidity, left out and the collapsed point, established number of trees, species richness of grass species and tree species, coverage, pest status, and invasion of disturbance species. The re-vegetation method was evaluated by each experiment zone which has different mixing ratio. As a result, experiment zone A was rated 45 points out of 60 rating points as the best re-vegetation method. However, this study result has been derived from one construction and short-term monitoring. In order to derive the suitable and dependable mixing ratio, conducting an objective re-vegetation method evaluation and long-term experiment and monitoring is required.

Four recycling scenarios involving pyroprocessing of spent fuel (SF) have been investigated for a 600-MWe transmutation sodium-cooled fast reactor (SFR), KALIMER. Performance evaluation was done with code system REBUS connected with TRANSX and TWODANT. Scenario Number 1 is the pyroprocessing of Canada deuterium uranium (CANDU) SF. Because the recycling of CANDU SF does not have any safety problems, the CANDU-Pyro-SFR system will be possible if the pyroprocessing capacity is large enough. Scenario Number 2 is a feasibility test of feed SF from a pressurized water reactor PWR. Thefsensitivity of cooling time before prior to pyro-processing was studied. As the cooling time sensitivity of cooling time before prior to pyro-processing was studied. As the cooling time increases, excess reactivity at the beginning of the equilibrium cycle (BOEC) decreases, thereby creating advantageous reactivity control and improving the transmutation performance of minor actinides. Scenario Number 3 is a case study for various levels of recovery factors of transuranic isotopes (TRUs). If long-lived fission products can be separated during pyroprocessing, the waste that is not recovered is classified as low- and intermediate-level waste, and it is sufficient to be disposed of in an underground site due to very low-heat-generation rate when the waste cooling time becomes >300 years at a TRU recovery factor of 99.9%. Scenario Number 4 is a case study for the recovery factor of rare earth (RE) isotopes. The RE isotope recovery factor should be lowered to ${\leq}20%$ in order to make sodium void reactivity less than <7$, which is the design limit of a metal fuel.

The idea of Sustainable, first mentioned in "Our Future (Bruntdland)" from the United Nations report released in 1987 has been highly affect design disciplines in developed countries in 21st century. It relocated industrial society and structure's attentions to nature and recourse conservation and reuse. Designed and manufactured products eventually disposed and it leads to waste of resources as well as creates environmental issues. Unfortunately, vast majority of designers starts designing without anticipation of this matter and produce more believing this leads to more sales. However shorter life of a product will create bigger increase of resource consumption and waste than, importance of re-usage and recycle will eventually increase. In modern furniture industry metal and plastics are frequently used beside wood that material has been diverse than in past. However, there are lack of plans and regulations of re-usage of those material due to difficulties of separating each different materials and collecting due to it's size. This study would like to look into recycling rate, methods and usage of three major materials (wood, metal, plastic) that is typically used in current furniture industries. Furthermore, see the potential of sustainable furniture by analyzing furniture practices made by each different recycled material from old furniture and what designers should consider to achieve feasibility of sustainable furniture.

This study investigates the main trend of LOHAS, examines and analyzes the LOHAS marketing cases of the fashion industry, and proposes an effective LOHAS marketing strategy for the domestic fashion market. Data were collected from Naver, Google and Daum from 2005 (when LOHAS began to be recognized) to October $31^{st}$ 2010. We searched the research material with keywords related to the research subject (such as eco, green, well being, echo-friendly, LOHAS, sustainable, environmental management, and green management) to conduct a theoretical and exploratory study through qualitative analysis. The data are analyzed with three types such as personal value of eco-friendly fabric, economical value of recycled fabric and re-use or re-form, and social-ethical value of distribution and promotion. The research results show that LOHAS marketing activities focused on personal values and social-ethical values (rather than economical value) and from an eco-friendly management centered on merchandise; in addition, an eco-friendly supply chain management incorporated with a management system were applied. LOHAS marketing strategies at home and abroad revealed some differences in the cases of eco-friendly fabric, recycling, and fair trade.

Fashion is one of the main environmental pollution industries. To reduce pollution, much of the deadstock clothes are given a new value by being redesigning based on the designer's competency. This study aims to promote the revitalization of redesigning by analyzing and presenting hybrid design characteristics of the Sacai design collection, as a redesigning brand, and formative element characteristics of redesigning. A theoretical study using previous research on redesigning and related books and an empirical study analyzing the Sacai Collection were conducted. Based on the study results, there are four types of redesigning processes; recombination of heterogeneous clothing structure, reorganization by reversed function and position, reorganized composition by material processing, and mixing of heterogeneous materials. In the recombination of heterogeneous clothing structures, heterogeneous materials and structures coexist by combining the clothing components with other clothing elements. The second is the reconstruction by subversion. The third is reconstruction by material processing. The fourth is a mixture of disparate materials. This study has innovative redesign features from Sacai designs, and there are plans for a follow-up study that will analyze the work of another designer who is recognized for the excellence in redesigning.

Whereas the necessity for recycling and reuse is being emphasized owing to the depletion of resources and waste disposal problems caused by the continuous development of the industry, the importance of remanufacturing has been highlighted recently. Re-manufacturing involves a series of processes in which failed disposal or aging goods are recovered to a state similar to that of a new product. In this regard, machine tools, which are large structures, can achieve the effect of remanufacturing. Among the various elements constituting the machine tool, the main spindle portion that affects the processing precision is critical. Therefore, this study is conducted to derive improvement measures for the main axis of an old Miller planner via reverse engineering and central composite design, which is one of the core processes of remanufacturing.

The study was to grasp features of new material applicable to housing space in the sustainable side by analyzing materialistic features of new material and features of sustainable material with sustainable new material. Through analysis on sustainable new material, the study deducted the below conclusion. First, through the precedent studies, the characteristics of sustainable materials have been classified into eight categories : friendly healthiness, non-toxicity, comfortableness, naturality, recycling, harmlessness of environment, separate collection, reusability. After the criteria have been brought up from new material applicable to housing space in the sustainable. Second, in materialistic Characteristics of new material, 'New Process' was mainly applied. There was no any new material applied to 'new raw material'. Therefore, it is thought that it is necessary to study on development of perfectly new material and to study on new material to apply material used in other fields to finishing material of dwelling space. Third, in Characteristics of sustainable material, 'Re-serviceability' appeared most and 'Non-toxicity' and 'Recycling' appeared in the next. 'Friendly Healthiness' and 'Separate collection' appeared only one on the other side. Therefore, it is judged that it is necessary to develop and study new material including health components considering user's health, function for health increase and function to grope comfort for humans. Finally, after researching and analysis the criteria by recently presented the new material, it has been concluded that the standard can be used as the criteria of new material for the possibility of application in housing space. On the basis of the study, the author will carry out analysis on sustainable new material minutely and utilize it as basic data to suggest a standard of sustainable new material applicable to dwelling space in the future.

Today, many pregnant women also advance up the business ladder and remain very active. They are consequently increasingly aware of the clothes they can wear. Despite these social changes, maternity wear has not been specially designed to satisfy the consumer's demands. From this, the purposes of this study are to investigate the current status of maternity wear and the apparent buying trends of pregnant women through a customers' opinion survey and interviews for the future maternity markets. In summary, the survey and interviews illustrate some important points which are that: Firstly, not all pregnant women buy maternity wear. Some pregnant women said they couldn't find enough difference in maternity wear prices even though they would like to buy some, commenting that maternity clothes were too expensive for such a short period of time. Also some already had maternity wear from a previous pregnancy, or had been passed on from friends and family. Secondly, on the other hand, many respondents were strongly concerned with style and quality rather than price because they agreed that there were not enough suitable maternity clothes for work and special occasions. Therefore some respondents would buy a maternity outfit for a special occasion. It also indicates that for a particular time, place or occasion like a party, wedding or other celebration, some respondents would buy a special outfit to make themselves feel good. Finally, according to the survey, the most important design concept is for wearable designs which change with the body during pregnancy; followed closely by designs which are able to be re-used when the pregnancy has finished. Nowadays, as recycling and saving resources are the biggest issues, if maternity manufacturers are encouraged to develop new products incorporating these new design concepts, more maternity markets will be developed to buy maternity wear.
