This paper proposes a hybrid genetic algorithm(HGA) for the classifier ensemble selection. HGA is added a local search operation for increasing the fine-turning of local area. This paper apply hybrid and simple genetic algorithms(SGA) to the classifier ensemble selection problem in order to show the superiority of HGA. And this paper propose two methods(SSO: Sequential Search Operations, CSO: Combinational Search Operations) of local search operation of hybrid genetic algorithm. Experimental results show that the HGA has better searching capability than SGA. The experiments show that the CSO considering the correlation among classifiers is better than the SSO.

Since around 1990. some experimental and shocking ugliness images have been expressed in Fashion and Make-up as well as Fine arts. The purpose of this study is to investigate the trends of ugliness images expressed in Modern Make-up from 1995 to 2003, especially focusing on color, and to enlarge the expressions through formative elements and to anticipate the prospect of Make-up in the future. Ugliness is the most negative aesthetic value which is lack of beauty. The 20 century art trends representing the ugly shape have been distorted or deformed or destroyed and extremely exaggerated with yellow, red, black, blue, white, green. The image and color of ugliness can be summarized as historical, avant-garde, decadence, de-constructive, humorous, futuristic trend and Most of colors are the achromatic ones like black, white, dark gray and red. blue, dark brown and so on. These colors cause some negative attributes such as fear. anger, death, devil, Pain, bad, ill omen, sorrow, despair and the like. At the turning Point in 21C are to be extended the range of color according to the experimental attempts such as informal, collage, graphic and the forth. Lastly, The characteristics of ugliness images expressed in the color of Modern Make-up have been analyzed into formlessness and inaccuracy and deformation by Karl Rosenkranz＇s theory.

Ever increasing fuel prices, almost doubled in the last three years, and global pressure to reduce their environmental impact have been enforcing commercial vessel operators and designers to re-assess current vessel designs with emphasis on their propulsion systems and operational practices. In this paper the "Inclined Keel Hull (IKH)" concept, which facilitates to use larger propeller diameter in combination with lower shaft speed rates and hence better transport efficiency, is explored for a modern 3600 TEU container vessel with the aim of fitting an 13 % larger diameter propeller (and hence resulting 20% lower rpm) to gain further power saving over the similar size basis container ship with conventional "level keel" configuration. It appears that successful application of the "inclined keel Hull" concept is a fine balance amongst the maximum gain in propulsive efficiency, minimum increase in hull resistance and satisfaction of other naval architectural and operational requirements. In order to make the concept economically more viable, this paper concentrates on the fore body design with the possible combination of increase of volume in its fore body to recover the expected volume loss in the aft body due to the space for larger propeller and its low wave-making resistance to minimize the efficiency loss using a well-established optimization software.

This study was carried out under the appropriate conditions of moisture content(60~70%), C/N ratio(25~30), and C/P ratio(30~35) on the mixed materials of cow dung and rice hulls. The good mixing ratio of cow dung and rice hulls was woth to one on volume basis which was able to adjust to the moisture content and C/N ratio of the mixing material. During fermentation pile period, the mixing ratio of control, non-aerated pile with turning was two to one and that of aerated pile with blower was two ti one. In fermentation pile period, average temperature of aerated pile was $55{\sim}65^{\circ}C$ and it was more higher than control of $40{\sim}50^{\circ}C$ non-aerated pile. While total nitrogen content of aerated pile was lower than that of the control, total carbon content and C/N ratio were higher. In cure pile period, the temperature and C/N ratio of aerated pile were increased at the early stage and then they were decreased, but total nitrogen and total carbon contents of aerated pile were increased in process of days. Final product in aerated pile had more fine particles and was good for the growth of cucumber seedlings than control.

This study was designed to assess profile preferences among Korean youths in the year 1992. Facial esthetics was evaluated by means of silhouette profiles, eliminating the influence of a number of aspects that may affect judgment when normal lateral photographs are used. The main points of preference to be clarified here are as follows. First, on facial convexity, Second, on nasion depth, Third, on mentolabial sulcus depth, Fourth, on the position of upper and lower lips, Fifth, on facial type according to Angle's classification of malocclusion, Sixth, on Song's tangents. The 54 subjects printed in questionnaire as black and white silhouettes were selected from 300 tracings from cephalometric radiographs of people whose age ranging from 11 to 20 years. Photographs of six female subjects were retouched by computer graphic software and printed in color and black/white photographs which were used for adaptation of eyes of participants in selecting profiles in silhouette. They constitute 2 questions. The 54 subjects were grouped as 22 questions, each of them composed of 6 subjects, according to the aspects to be clarified. Twenty four questions in total were asked to assess profile preferences. For the assessment, the profile line, the facial esthetic triangle, Song's tangents, and Angle's classification of malocclusion were introduced. The profile line is composed of 11 component points which are Trichion, Glabella, Nasion, Pronasale, Subnasale, Labrale superius, Stomion, Labrale inferius, Supramentale, Pogonion, and Gnathion. The facial esthetic triangle is composed of 3 tangents: A-tangent which is the tangent of dorsum of nose, B-tangent which is the line passing through Sn and Ls, and C-tangent which is drawn on the turning point of the curve which lies between mentolabial sulcus (Sm) and pogonion (Pg). Angle's classification has 3 types of malocclusion which are Class I, Class II, and Class III. Class II malocclusion is subdivided into Division 1 and Division 2. The participants of the survey were composed of 861 college students (448 male students, 413 female students) whose majors grouped as Fine Arts. Liberal Arts, and Natural Sciences, and whose mean age 21.8 years. The statistics program SPSS/PC + of SPSS Inc. was used to analyze answers of participants. Crosstabulation, Chi-square test, and Kendall test were done. The conclusions are as follows: First, Korean youths have a tendency to prefer the slightly convex face to the flat or concave face. Second, they prefer a moderately deep nasion. Third, they prefer a moderately deep mentolabial sulcus. Fourth, they prefer the position of lips which are near to Ricketts' E-line. The position of the upper lip which is slightly posterior to E-line is preferred. The upper lip which lies too far anterior or posterior to the lower lip is not perferred. Fifth, they prefer most, according to Angle's Classification of Malocclusion, Class I facial profile which has a slight inclination to Class II division 2. The order of preference is Class I, Class II division 2, Class III, and Class II division 1. Sixth, they prefer the type 2 and 3 of Song's tangents. The facial profile within which A-and B-tangent meet is preferred. The facial profile which has Cotangent that .meets with A-tangent slightly posterior to the crossing point of A-and B-tangent or that parallels with B-tangent is preferred.

"Printing is an Art of reproduction & a Technique of However printing has extended its limitation from a genre of reproduction itself and now it stands on the turning point as an art such as painting or sculpture which expresses artist's originality. Early Printing has had relations in depth with press printing in terms of information recording, preservation, and transmission. It was acknowledged value in a way of information satisfaction different from how it is valued as a pure art today. But, later printing has transferred its function from a mean of reproduction to pure art due to the development of printing skills and photography invention. It can be said that the concept of modern printing is taking over its genealogy as a creative work not as just printing. Also its expression capability is widen to dimensional printing and high-tech multimedia from original tradition techniques. As we discussed above, modern painting is very open to various changes. This modern painting aspect can be seen as an extended interpretation of 'board' concept. This dissertation raises a question why monotype and monoprint couldn't secure its position in printing history in spite of numerous artists' tryouts in its way. Monotype and monoprint fundamentally based on intaglio technique in its history. Yet, its systematic study hasn't been worked out. This is because of the lack of recognition of monotype and monoprint's originality as printing. Especially in monoprint, it has known as an early stage in copperplate printing process which is an attempt to solve the technique limitation or trial work for edition. Likewise the reason why monotype and monoprint remains at the edge of printing border ambiguously is because of conceptual, technical characteristics which are against traditional printing. In traditional printing, the concept of board is important as a method of reproduction. Different from the fact, monotype and monoprint accept the form of medium 'board' conceptually out of limited condition as mentioned. Thus monotype and monoprint hasn't stand out for several reasons until late 20th century when it started come out to public as people starts to have interests that works from famous artists are actually based on monotype and monoprint. This dissertation likes to step into the monotype and monoprint theoretically which is not well known in domestic and try to study the meaning of monotype and monoprint as a printing medium which is also hasn't been considered sincerely. For this study the process follow as below. First, look into how monotype and monoprint has a concept and history. Next, check differences through comparison with traditional printing and how printing can be understood in what aspects at the same time. After, verify how monotype and monoprint have influence on the acceptance of extended concept of 'board'. This study will show the expressional possibility of monotype and monoprint which has already known as 'tableau printing' in today's situation where adventurous experiments of printing medium are going on with the development of technology.

In recent observations on vestibular eye movements in mammals, reported by several different workers, it was indicated that the pattern of reflex eye movement from semicircular canal nerve stimulation in rabbits was different from that observed in the other species such as cats and dogs. Observing the different anatomical features of the extraocular muscles of rabbits, Kim ascribed the different pattern of eye movement of rabbits to the functional difference of inferior and superior oblique muscles from those of other species. Present experiment was carried out to elucidate a physiological mechanism underlying in such particular pattern of reflex eye movement in rabbits. An individual canal nerve was selectively stimulated, under a dissecting microscope, by a fine electrode induced into an ampulla through a hole provided on the wall of corresponding osseous canal, and responses of the extraocular muscles were checked by recording the isotonic changes of muscle length. Following results were obtained. 1. Direct stimulation of the superior or inferior oblique muscles Produced upward or downward movement of the eye turning toward medial side respectively. 2. Stimulation of the unilateral canal nerve Produced a marked contraction of a main contracting ocular muscle and simultaneous relaxation of an antagonistic muscle in both eyes. Less potent contraction of an additional ocular muscle was observed and it appeared to augment the function of the main contracting muscle in the ipsilateral eye. 3. Stimulation of superior semicircular canal nerve caused a primary contraction of superior rectus, synergic contraction of superior oblique and relaxation of inferior rectus in ipsilateral eye. Contraction of inferior oblique and relaxation of superior oblique were observed in the contralateral eye. 4. Stimulation of lateral semicircular canal nerve produced a primary contraction of medial rectus, synergic contraction of superior oblique and relaxation of lateral rectus in the ipsilateral eye. Contraction of lateral rectus and relaxation of medial rectus were observed in the contralateral eye. 5. Stimulation of inferior semicircular canal nerve produced a primary contraction of superior oblique, synergic contraction of superior rectus and relaxation of inferior oblique in the ipsilateral eye. Contraction of. inferior rectus and relaxation of superior rectus were observed in the contralateral eye. 6. Upon stimulation of individual canal nerve, the pattern of eye movement in rabbits is different from those of cats, however, the responses of the extraocular muscles appear to be similar in two species. Therefore, it is concluded that the different Pattern of eye movement in both species are not due to the possible difference of vestibule-ocular reflex pathways but to the functional difference of superior and inferior oblique muslces.

The Musculoskeletal Disease has been ignored or turned away due to the difficulty of diagnosis and the vagueness of judgement up to now. Contrary to other diseases, there were many cases where the character of the Musculoskeletal Disease wasn't revealed through the objective inspection. And that's because the Musculoskeletal Disease appears for the most part due to muscular defect so it is impossible to diagnose the muscle by X-ray diagnosing the bone and it is also impossible to diagnose the fine damage of the muscle or tendon even by advanced device like MRI. As the nervous blood vessels or acupunctures pass through or are next to the muscle, the tension of the muscle put pressure on these so can become the direct or indirect causes of various kinds of pains or intern diseases. But in spite of that, for lack of proper equipment diagnosing the state of the muscle(Shortened.. Relaxed... or Hardened...) the muscle has been disregarded or neglected intentionally or unintentionally. While many people think themselves to be a muscular expert, if they don't see the shape of the muscle, that is just like blind treatment. But as now the equipment diagnosing the state of the muscle is developed, it seems that this problem can be settled. It was attempted in this study that the muscle or skeleton of the Musculoskeletal disease patients was diagno the treatment order and method were decided by a questionnaire survey and simple inspection, and the Musculoskeletal correction exercise using the muscle management and sling system made them escape from the Musculoskeletal disease, turning their muscle into more flexible and stronger muscle. As a result notwithstanding the limited treatment period '12 times', the improvement rate was as high as 74%, which showed that the muscle management and Musculoskeletal correction exercise had a great effect on the symptom improvement of the patients. If the treatment times had increased, the improvement rate also would have increased more.

Despite the fact that the importance of islands and oceans is increasingly being emphasized as they are recognized as alternative spaces for the future, some islands that have not been designated as cultural assets have lost their natural and cultural landscapes to development projects and other plans for turning islands into tourist resources, and are still in the process of being destroyed. Unlike old perceptions of islands, islands, in the minds of people living in the modern age, have become places for taking a quiet rest or enjoying and appreciating the undamaged beauty of nature itself. Keeping up with the trend of people increasingly visiting the islands these days, it is high time to prepare plans for the promotion, preservation management, and usages of islands based on researches of islands with excellent natural landscapes and through the designation of these islands as cultural properties. As the first step of studying island landscape resources as resources of cultural assets, the current study includes literature reviews and field investigations of Gwanmaedo and Yeongsando, two islands that have been selected as prestigious villages and are part of the Dadohaehaesang National Park. Based on these preliminary investigations, landscape resources showing distinctive natural landscapes and cultural sceneries were selected and analyzed in detail, thus presented for their value as resources of Scenic site and future research.

Polly-pigs technique was developed to remove internal rusts and scales from service pipes in the building by using Polly-pigs that were used as various applications in conventional plant pipelines. Results of cleaning experiments on 15mm GSP(Galvanic Steel Pipe) showed that hydraulic cross sectional area was more increased from 3.5% to 15.4% for straight part or elbow parts of several test pieces. Results of optical analysis also showed that rust and scale removed mostly by KDP series(only consisted of Polyurethane) were outside red colored scale ($Fe_2O_3{\cdot}H_2O$), and there was a limitation to the removal of black colored scale($Fe_2O{\cdot}nH_2O$) that was below red colored scale. But it was evaluated that KDPS series coated fine sand with KDP series could remove not only red colored scale but also black colored scale and more increase hydraulic cross sectional areas of 15mm GSP old service pipes from 13.0% to 17.9%. After KDPS series cleaning, hydraulic cross sectional areas of them were recovered from 95.9% to 99.5%. Turning force of Polly-pigs was largely improved by the effect of Helical guide vane(Cleaning v/v) and Rotating wing(Pigs), and the number of pig rotating also more increased sixteen times compared with conventional cleaning system without Helical guide vane and Rotating wing. After KDPC series cleaning of 100mm GSP old service pipes that hydraulic cross sectional areas were 90%, hydraulic cross sectional areas were almost recovered perfectly like new service pipes. Additionally pressure necessary to run Polly-pigs m 100mm GSP was lower and cleaning efficiency also was higher than 15mm GSP cleaning. Therefore it was thought that as the diameter of pipe was more increased, pressure necessary to clean service pipes was more decreased and cleaning efficiency was more increased in Polly-pigs cleaning.
