Water quality improvement processes for stagnant area consist mainly of technologies applying vegetation and artificial water circulation, and these existing technologies have some limits to handle pollution loads effectively. To improve the purification efficiency, eco-friendly technologies should be developed that can reinforce self-purification functions. In this study, a multi-functional floating island combined with physical chemical biological functions ((1) flotation and oxidization using microbubbles, (2) vegetation purification and (3) bio-filtration with improved adsorption capacity) has been developed and basic experiments were performed to determine the optimal combination conditions for each unit process. It has been shown that it is desirable to operate the microbubble unit process under conditions greater than $3.5kgf/cm^2$. In vegetation purification unit process, Yellow Iris (Iris pseudacorus) was suggested to be suitable considering water quality, landscape improvement and maintenance. When granular red-mud was applied to the bio-filtration unit process, it was found that T-P removal efficiency was good and its value was also stable for various linear velocity conditions. The appropriate thickness of filter media was suggested between 30 and 45 cm. In this study, the optimal design and operating parameters of the multi-functional floating island have been presented based on the results of the basic experiments of each unit process.

This study began with the question: "what influence would the width of river surface have on visual preference, provided that the environment surrounding the river does not change?" to evaluate the visual preference factors of the river scenery which could vary according to the change of water level. To estimate the minimum flow needed for river sceneries, field survey of Youngsan river was carried out to collect the field data and evaluated the visual preference factors to obtain a most preferred W/B ratio. At Youngsan bridge location, the feeling of open space factors, physical characteristic factors and complexity factors appeared to have significant relations to visual preferences. At Imgok bridge location, complexity factors, aesthetic factors and physical characteristic factors have significance to visual preferences. As a result of multi regression modeling, it was found that physical factors affected visual preferences the most at urban river locations and complexity factors affected the most visual preferences at rural river locations. As a results of this study, the most preferred W/B ratio was estimated as which vary from 0.5 to 0.7 and this results can contribute to the field of river landscape design to maximize the users' satisfaction level.

When a human being grew older, followed by visually and perceptually impaired, and dementia, it jeopardizes safety and life unless supportive design is secured for a living environment. This supportive space is based on universal design concept which offers safe-oriented, and simple use by incorporating gender and physical/mental limitation. The study of purppose was to examine the appropriateness of barrier-free standard for seniors' living in apartment through IPA. Chi-square analysis found that satisfaction with BF space is lowered as aging is continued and for female group. Regression analysis indicated that sink was the prime predictor in satisfaction, and stair/elevator was the most important variable. IPA concluded that sink, bath, shower/locker and alert/egress were prime BF indexes to be improved among 14 elements, implying careful design in sanitation area for seniors.

Background and Objective : Soft palate plays a great role in function of speech and swallowing. Ablation of tonsil cancer results in multi-demensional defect including soft palate in most cases and restoration of the postoperative oral cavity function is a continuing surgical challenge. Although a variety of techniques are available, radial forearm free flap has been known as an effective method for these defect, which offers a thin, pliable, and relatively hairless skin, and a long vascular pedicle. The aim of the present study is to report the speech and swallowing function test results of our 5 consecutive radial forearm free flaps used for tonsil cancers. Materials and Methods : We reviewed the medical records of 5 patients who were offered intraoral reconstruction with a radial forearm free flap after ablative surgery for tonsil cancers, from Dec. 1997 to Oct. 1998, and analyzed the surgical methods, complications, and speech and swallowing function test results. We have examined with modified barium swallow to evaluate postoperative wallowing function and articulation and resonance test for speech. Results : The tumor sizes by TNM stage(AJCC, 1997) were T1(1), T2(2), and T4(3). The paddles of flaps were tailored in multilobed designs from oval shape to pentalobed design and in variable size from 24$cm^2$ to 108$cm^2$(average size = 78.4$cm^2$), according to the defect after ablation. This procedures resulted in satisfactory flap success and functional results all but 1 case of flap contracture in 2 postoperative week, achieved early oral diet until 16-57 postoperative day(average, 28 days) and social speech. The oropharyngeal defect including soft palate reconstruction with radial forearm free flap might be an excellent method for the maximal functional results, after ablative surgery of tonsil cancer that results in multidimensional defect.

Current principles of designating a smoking area within a non-smoking area rely on mere compartmentalization. This causes non-smokers aversion against smokers and smokers complaints about anti-smoking policies, which means both of them are not satisfied with the current scheme. In addition, such a system, far from the original intent of the law, does not provide appropriate respect for people's rights. The biggest problem of the current scheme is that smoking areas are not separated from non-smoking areas. Japan has continued installing independent smoking areas since 2002 and witnessed a decrease in the smoking rate. The country's success is attributable to: the state's active intervention in connection with enterprises; continuous environmental improvements and creation of goods; 'smoking etiquette' campaigns; and the sociality and group consciousness of Japanese people. It is recognized that the synergy of the designation of independent smoking areas and such multi-faceted efforts has led to the nation's accomplishment. Hence, it is required to install independent smoking areas in non-smoking areas in Seoul in order to respect the rights of smokers and non-smokers and resolve conflicts between them. It is not suitable to merely model after Japan's case, however, studies and guidelines that are tailored to Korea's own environment and social atmosphere are required. To ensure that the people recognize the necessity for smoking areas, a social consensus is formed and proper smoking areas are established in a systemic manner, a system for that purpose should connote a symbol of the social consensus and consequent guidelines should take physical elements, human activities and semantic assignment into consideration. This study aims to present basic guidelines to install separated smoking areas, which will keep distance between smokers and non-smokers, form a social consensus and establish a sound smoking culture. These would ensure that the rights of both smokers and non-smokers are fully respected and that government policies are trusted by the people.
