This paper delves into the recent 'paintings' of African-American artist David Hammons, which combine rubbish-like plastic wraps with the abstract-expressionist style paintings. In straddling between rubbish and art object, his works tend to blur the boundary drawn between two opposite categories in value, art and garbage, provoking the sophisticated taste of Upper-East-side white community in Manhattan, New York. Choosing the venue of his exhibition at a commercial gallery, Hammons's creative efforts is also a critique of what can be seen as the dominance of abstract expressionism and white elitism in American art history. The artist is known for his use of unconventional materials in art making such as black hair, barbecue bones, and elephant droppings, ones that are often associated with African-American experiences in all different levels. Since his debut in the art scene in the 1970s, Hammons has pursued the view of art-making as a medium for provoking contentious issues of racial relations in the States. On the other hand, the reception of Hammons's work as African-American art can be potentially quite limiting, overlooking as it does multi-faceted meanings of his art practice. His unconventional approach to art often took him outside art galleries and museums, where he was seen using a variety of common materials for site-specific installations and performances. Staged in different parts of Manhattan, these acts of art making traverse seemingly opposite communities and cultures, often blurring their boundaries. Hammons's artistic practice can label him what Abdul Jan Mohamed calls "specular border intellectual", revealing as it does the symbiosis of binary oppositions that is basic to the experience of communnal living.

This study traces the origin, evolution, and current state-of-the-art of engineering-oriented water-quality management and modeling. Three attributes of polluted water underlie human concerns for water quality: rubbish (aesthetic impairment), stink (ecosystem impairment), and death (public health impairment). The historical roots of both modern environmental engineering and water-quality modeling are traced to the late nineteenth and early twentieth centuries when European and American engineers worked to control and manage urban wastewater. The subsequent evolution of water-quality modeling can be divided into four stages related to dissolved oxygen (1925-1960), computerization (1960-1970), eutrophication (1970-1977) and toxic substances (1977-1990). Current efforts to integrate these stages into unified holistic frameworks are described. The role of water-quality management and modeling for developing economies is outlined.

For the construction of safe and clear urban environment, it is necessary that we identify the rubbish waste volume and we know the accuracy volume. In this paper, we developed the algorithm which computes the waste volume using the stereo camera for enhancing the environment of waste repository. Using the stereo vision camera, we first computed the distortion parameters of stereo camera and then we obtained the points cloud of the object surface by measuring the target object. Regarding the points cloud as the input of the volume calculation algorithm, we obtained the waste volume of the target object. For this purpose, we suggested two volume calculation algorithm based on the uniform meshing method. The difference between the measured volume such as today's one and yesterday's one gives the reposit of waste volume. Using this approach, we can get the change of the waste volume repository by reading the volume reports weekly, monthly and yearly, so we can get quantitative statistics report of waste volume.

The purpose of this study were to examine actual conditions of apartment residents living with their companion animals and to identify their residential stress and needs of planning elements under those conditions. Questionnaire survey was adopted in this study, and 100 cases were used for data analysis. The subjects for this study were limited to the residents breeding pets in their apartments. The results of this study are as follows: Most of the residents share their living spaces with pets together like their family without spatial restrictions. They indicated problems related to breeding pets in their residence such as walking the dog, cleaning home, leaving pets alone, noise and unpleasant smell. However, they didn't seem to be stressed a lot for their living environments. In terms of residential planning elements, floor plans for effective natural ventilation, balcony with sufficient sunlight, sound proof system, easy-maintenance interior material, unlash area, rubbish bin, mechanical ventilation and central vacuum system and safe electric outlet were highly indicated.

This paper addresses major issues in localising sound sources in space using the experimental data set of head-related responses in the time or frequency domain. They come from the technical realisation steps for implementing the convolution of HRIR's with sound sources, the cross-talk cancellation for transaural filtering, the matched time delay compensation, etc. in real, those technical matters seem to be minor because they can be realised in off-line signal processing schemes. This paper puts much emphasis on what we misunderstood about the sets of HRTF's or HRIR's, More specifcaily, the sets of HRTF's or HRIR's of course supply relevant information to sound localisation but include much useless 'rubbish' that have made for us to fail to put spatial image into real souno signals such as voices and music's. This paper proposes possible reasons for such failure and, furthermore, introduces detained subjects that should be challenged so as to resolve them.

This study was undertaken to investigate the ratio and compositions of tailings of the tailings return unit in the commercially available head-feed combines. The ratio of the returned tailings to the sum of the threshed grain and the returned tailings was 2.3~7.2% for various varieties of rice and operational conditions of combines tested and increased as the feeding rate and the cleaning air volume increased. The analysis of the returned tailings showed that the composition of rubbish and short straw was decreased as the feeding rate and the cleaning air volume increased.

The purpose of this study is to investigate safety and dangerous awareness of environment on walking trails. For this purpose, questionnaire survey are carried out by people who had experience using walking trails during 2016. It is evaluated that environments of walking trails located inside big cities are inferior than ones located in small and medium-sized cities and countryside in air pollution, bed smell, water pollution, noise, and waste. Needs about management and number installed public restroom are high for hygienic environment of walking trails. With waste treatment, users of 2.4 percentage are showed improper behavior that they left their rubbish at the place out of view but others bring their trash. Accident likelihood is highly appreciated and possibility of physical accident like slipping is showed at the highest. The reasons of accident on walking trails are responded with carelessness of walkers and improper of installation or management of safety facility at the most. For safety environment of walking trails, needs of installation of safety fences and notices of dangerous area are requested. In order to separate prevention from paths of walking trails, signposts are needed at visual clearness, maintenance, installation with proper interval and location, and correct contents. Respondents of 2.4 percentage have experiences of accident on walking trails and physical accident like slipping is occurred at the most.
