  • Corn grits spiked with fumonisin B$_1$(FB$_1$) at a level of 5 $\mu$g/g were extrusion cooked in a co-rotating twin screw extruder at different temperatures(140, 160, 18$0^{\circ}C$) and screw speed(80, 100, 120 rpm). About 41~45% of the spiked FB$_1$ was lost when the corn grits were extruded. Both the barrel temperature and the screw speed. however, did not significantly affect the FBI reduction in extruded corn grits. More reduction of FB$_1$ was found in the presence of glucose than with fructose or sucrose when the corn grits were extruded with sugar at 14$0^{\circ}C$, 120 rpm. About 51, 34 and 19% of spiked FB$_1$ were remained in extruded corn grits with glucose at levels of 2.5%, 5%, and 7.5%, respectively.

  • Considering the shape of a valve plate in design is important for reducing the pulsation phenomenon, which is a negative factor in pump performance. The purpose of this study is to propose an optimized method for a valve-plate V-type notch of a piston pump by modeling and simulation. The method uses $SimulationX^{(R)}$, a commercial hydraulic analysis program, and to provide data for the designing of the notch. The opening areas are determined by performing kinematic analysis of the notch part where the opening area changes rapidly. After applying the result analysis, the main effects on maximum pressure pulsation and maximum backflow according to the notch design factors are analyzed by using the full factorial method of experimental design. The optimized solutions are derived for the notch design variables, based on the analyzed data.

  • The ultimate bending moment of ships is one of the principle strength considered in ship design. Several methods have been proposed to predict the ultimate bending moment and its major part is, in general, predicting the ultimate compressive strength of stiffened panels. In this paper, made is the review on the methods and formulae of predicting the ultimate compressive strength and they are applied to predicting the ultimate bending moment. Safely levels of three bulk carriers have been derived evaluated for two loading conditions, stray, light ship condition and full load condition, and wave bending by Classification Society Rule(ABS, DnV and Lloyd Rule). The present reliability analysis problem is strictly non-linear and the Advanced First-Order Reliability Method has been used. From the results of parametric studies, the methods of predicting the ultimate compressive strength of stiffened panels are compared from the view point of their applicability to the reliability assessment of ships structures. The paper ends wish a brief discussion drawn from the parametric studies and the extension of the study is described.

  • This study researched the art-educational thoughts as a modern idea influenced with the social and philosophical transitions in the 19th century. Moreover, this study focused on Frank Lloyd Wright's educational thoughts, because those educational revolutions had appeared as one of the results that Western society's character was rapidly changed by those revolutions, so called, Industrial Revolution, American and French Revolution, and Cultural Revolution of Romanticism, from late 18th century, and eventually because that revolutionary educational ideas had closely and basically many relations with Wright's thought. As a result, even though Wright's education such an apprenticeship was a traditional shape, which was not the old-fashioned educational method discipling to the skillful man, but against the existing education through the self-learning from experiences in nature. That is similar to transcendentalists such as Emerson who searched for having an inspiration in Nature. Namely, Wright himself had struggled against the existing dualistic educational concepts through Wright's monistic thoughts on art-education including architecture based on not naturalism but the philosophy of nature by romantic idealistic philosophers such as Shelling, Fickle, Kant, Hegel including with his Master, Sullivan, and by revolutionary educators such as Freobel, Ruskin, Dewey, and above all by his Unitarian doctrine. However, Wright's thoughts was at that time so radical, and as Wright himself acknowledged that, 'because the philosophy back of it, of course, as you know, is midway I guess between East and West', such all philosophical objects to influence on Wright were so abstruse idea which is usually called 'Romantic' or 'Mystic' that is mingled with East's and West's essence. That is, because Wright himself catched that the theories and methods of the art-educational thoughts would not be easily perceived, and he judged that in a word as a character which could not be taught. After all, Wright's romantic progressivist art-educational thoughts have not been perceived, disseminated in general and widely.

  • In this paper, we consider an efficient design of quantizers at sensor nodes for sequence-based localization (SBL) systems which recently show a competitive performance for in-door positioning, Since SBL systems locate targets by partitioning the sensor field into subregions, each with an unique sequence number, we use the distance samples between sensors and the sequences for quantizer design in order to propose a low weight design process. Furthermore, we present a new cost function devised to assign the number of samples and the number of unique sequences uniformly into each of quantization partitions and design quantizers by searching the quantization partitions and codewords that minimize the cost function. We finally conduct experiments to demonstrate that the proposed algorithm offers an outstanding localization performance over typical designs while maintaining a substantial reduction of design complexity.

  • Le Corbusier (1887-1965) is known as a great architect ranking with such master architects as Frank Lloyd Wright and Mies van der Rohe who produced great architectural achievements in an era from the dawning to the maturity of the modem architecture. His works are marked for their peculiarity in expressing his architectural concept as perceived through his artistic sensibility. He has brought the form of his architecture to perfect through the influence of Purism. His architectural concept has instigated him to construct the relations between structure, form and the notion of space through the 'Dom-ino' structural system and the 'Five Principles of the Modem Architecture.' As a result, he has become such an architect as has ripened his works by adopting the 'Modulor' for human measurement. During the decade from 1929 to 1939, he made public the 'Museum of Unlimited Growth' programs in an attempt to give a concrete form to his concept of 'unlimited space' spreading to all directions, which was actually visualized by the constructions of three art museums, located Ahmedabad and Chandigarh in India and Tokyo in Japan. Although a number of researches have so far been publicized on the works and the architectural ideas of Le Corbusier, no systematic research has yet been released on the idea of 'Museum of Unlimited Growth' as a matter of fact. Therefore, this study has set its purpose to grasp the peculiarities of his exhibition space design through an analysis on the characteristics of the 'Museum of Unlimited Growth' so designed as to reflect the concept of a space, which is centrifugally growing. With this purpose in mind, this research is also to suggest how the design of the 'Museum of Unlimited Growth' would influence the modem museum exhibit space. The contents of this study comprise the consideration on the early ideas of Le Corbusier, the typical features of the growing museum and the analysis as well as the integration of his works.

  • Composite column design is strongly influenced by the computation of the critical buckling load, which is very sensitive to the effective flexural stiffness (EI) of the column. Because of this, the behaviour of a composite column under lateral loading and its response to deflection is largely determined by the EI of the member. Thus, prediction models used for composite member design should accurately mirror this behaviour. However, EI varies due to several design parameters, and the implementation of high-strength materials, which are not considered by the current composite design codes of practice. The reliability of the design methods from six codes of practice (i.e., AS 5100, AS/NZS 2327, Eurocode 4, AISC 2010, ACI 318, and AIJ) for composite columns is studied in this paper. Also, the reliability of these codes of practice against a serviceability limit state criterion are estimated based on the combined use of the test-based statistical procedure proposed by Johnson and Huang (1997) and Monte Carlo simulations. The composite columns database includes 100 tests of circular concrete-filled tubes, rectangular concrete-filled tubes, and concrete-encased steel composite columns. A summary of the reliability analysis procedure and the evaluated reliability indices are provided. The reasons for the reliability analysis results are discussed to provide useful insight and supporting information for a possible revision of available codes of practice.

  • The qualitative and quantitative analyses of phospholipids in chloroform-methanol extracted crude and hexane extracted deodorized soybean oils were carried out by High-Performance Liquid Chromatography (HPLC). The phosphorus contents in hexane extracted crude, degummed, refiend, bleached and deodorized soybean oil were 510, 120, 5, 1.4 and 1 ppm, respectively. The chloroform-methanol extracted crude soybean oil had 800 ppm phosphorus. The phospholipids found in crude oil were phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine and phosphatidic acid. Only phosphatidylchonine and phosphatidylethanolamine were detected in the deodorized soybean oil. The HPLC method described in this report can separate and detect individual phospholipids in soybean oil at 0.1 ppm level in 30 min.

  • Vilhelm Wohlert is the Danish architect who designed Louisiana Museum of Modern Art near Copenhagen. Because of Louisiana Museum's popularity, Vilhelm Wohlert's name was started to be aware since 1990s. Although he is a well-known architect in Denmark, unfortunately his name is unknown in other countries. He designed various design projects from small scale furniture design to large scale museum and public projects. There are three programmatic categories in his architecture: exhibition programs including Louisiana Museum, residential program including private houses, and public programs including churches and schools. This thesis focuses on his residential design projects. Even though he designed a multi-family houses, Wohlert's house design consists of mainly one-off large private houses located in a nice natural environment. In chapter 3, the general history of his house projects was studied. Among them, the first exhibition house for Forum was explained more deeply to show Wohlert's early house design philosophy. In chapter 4, three built house projects were analyzed in detail. Analytical diagrams were used to show the key elements in the residential space. They are program composition, circulation, spatialization elements, final construction. His buildings have been compared with Alvar Aalto, Frank Lloyd Wright, and other Scandinavian architects. But there are some major differences that make Wohlert's design unique. In chapter 5, the case analysis results were summarized together to highlight the specific design characteristics found in Wohlert's residential design process. The universal spatial quality found in his residential projects can be applied in contemporary spatial designs.

  • The purpose of this study is to make a comparative analyzation toward abstracted emotional properties appeared in the museum exhibition spaces designed by the three masters of the modern architecture;Frank Lloyd Wright, Le Corbusier and Mies van der Rohe. In addition, this study will also aim to inquire into how the emotional properties have affected the third generation architects. It is especially expected that the 'emotional tendency' emerging in various fields of the present time can serve as useful information through the analysis of emotional design properties appeared in the exhibition space which is directly linked with the human lives. In order to achieve the purpose of the study, in New York by Wright, in Tokyo by Le Corbusier and in Berlin by Mies Van der Rohe were selected. As for the analyzation methodology to be adopted for deriving the aiming points at the emotional design, five criteria of analyzation have been established in order to understand the properties of the emotional area: they are (1) spatial affordance, (2) human congeniality, (3) emotional factors of the area, (4) constitution of the area and (5) expressive division of the area. Using these criteria, this study will reveal what are some of the emotional characteristics shown in each museums and its analytical result will be useful to apply to future museum design. It is especially expected that the 'emotional tendency' emerging in various fields of the present time can serve as useful information through the analysis of emotional design properties appeared in the exhibition space of design which is directly linked with the human behavior.
