The objective of the research being presented was to construct and calibrate a spectrometer for the analysis of single kernels of corn. In light of the difficulties associated with capturing the spatial variability in composition of corn kernels by single-beam spectrometry, a hyperspectral imaging spectrometer was constructed with the intention that it would be used to analyze single kernels of corn for the prediction of moisture and oil content. The spectrometer operated in the range of 750- 1090 nanometers. After evaluating four methods of standardizing the output from the spectrometer, calibrations were made to predict whole-kernel moisture and oil content from the hyperspectral image data. A genetic algorithm was employed to reduce the number of wavelengths imaged and to optimize the calibrations. The final standard errors of prediction during cross-validation (SEPCV) were 1.22% and 1.25% for moisture and oil content, respectively. It was determined, by analysis of variance, that the accuracy and precision of single-kernel corn analysis by hyperspectral imaging is superior to the single kernel reference chemistry method (as tested).

Many countries have adopted a single, well-described approach to the use of phototrophs for monitoring river water quality, which involves the use of indices related to diatom composition at a site. Increasingly these indices have focussed on assessing ambient phosphate concentration. However, there is a wide range of other methods which can provide additional information to make up for any weaknesses in the standard method. Some of these methods are reviewed briefly here. They can be useful, for instance, when considering temporal and spatial variability in phosphate concentration at a particular site and providing much more insight on heavy metal or pesticide pollution than revealed by routine water analysis.

The purpose of this study is to recognize the living space and life pattern transition which is expressed in the modernization course with the analysis of the Jeju rural houses. For this study, I choose 72 residences examples in 8 villages as the subjects which are changed by the spontaneous purpose of the inhabitants who live in Jeju area were chosen as the subjects. As for the research method, after visiting the subject residence directly, and the field study such as the actual estimation, observation and interview were performed.The conclusion of the study with these purpose are as follows. First, The opened spatial composition of the sitting-inclination is composed of the form which has the individual opened room and living room with the mechanism to grant the flexibility to the limited space and the structure for enduring the much-humid oceanic climate. Second, The life pattern shows the sitting life which usually uses the an-bang and living room with the seasonal change.

The purpose of this study is to grasp musical expression in the Monastery of La Tourette, an architectural work produced by an architect, Le Corbusier and a musician, Iannis Xenakis based on a musical piece, Metastasis. The results of the study on musical expression in the Monastery of La Tourette, which was done through analysis of correlation in expression between architecture and music, and spatial characteristics of this monastery, are as follows: First, in modern architecture and music, the expression of the space-time continuum concept is emphasized. Second, the architectural characteristics in this monastery that constitute musical expression are the Modular, confliction and fluidity in composition, plastic (acoustic) shape and symbolic shape. Third, these architectural characteristics are found to be expressed as counterpoint, alteration, temporality, acoustics and canon of music.

The purpose of this study is to examine the characteristics of unit plans in the high-rise mixed-use condominium and to provide the data fur architectural planning and design. The tools of statistical analysis are frequency, percentage, mean, cross-tab, and correlation. The results of this study are as fellows; The most frequently found shape of unit is a deformed polygon. The common rooms in housing units are dressing room, powder room, offset-kitchen, family room, passage, hallway, and foyer. The specially prepared spaces are wash room, home bar, independent porch, and garden. As to room size and area ratio in a dwelling unit, those of living room are biggest and highest irrespective of unit size. As the floor area of unit increases, does the size of each room and space but the area ratio of each room decreases. This research is made to develop an Apartment Information System. This integrated information system is to be designed to provide residents of high-rise mixed-use condominiums with convenient, economical, and safe life.

The evaluation of economy of wards is based on the building area. The parameters are nursing area per bed, occupied area per patient, and the portion of movement area. Three areas such as patient area, nurse area, and corridor area are devided. The results of analysis are as follows. At first, allocation of patient area has the highest priority. Even though nurse area is small, the patient area is relatively large. Secondly, the patient area is mostly determined by the type of rooms, such as single, double, etc.. Finally, the type of alley on the floor is important to economy. The single corridor type is the most economical followed by the double corridor type. the single loaded type shows the worst economy.

Large hospital designs try to accommodate functional needs and spatial organization. The purpose of this study is to propose an effective compositional method by horizontal interconnection of public circulation spaces with 'hospital street'. 'Hospital street' and network of public circulation spaces are major elements of consideration for the design of large hospitals, which not only connect functional components but also provide satisfying environment, amenity and patients' life.

This study employed the Semantic Differential(SD) technique for an empirical analysis of the borrowed landscape-the so-called interaction of landscape between space and nature-in traditional Korean space against the cultural backdrop of confucian ideology. Its findings are as follows: First, the study conducted a comparative analysis of the borrowed landscape between Sarangchae(Men's quarters) and Anchae(Women's quarters) and between Soteuldaemun(A lofty gate) and Sadangdaemun(A gate to an ancestral shrine), using the SD technique. Consequently, their marked distinction in the borrowed landscape were found to illustrate the influence of confucian ideology over spatial composition. Second, both the garden and the sky of Sarangchae appeared more open and dynamic, and soft, and comfortable, and warm compared to Anchae. Also, Soteuldaemun looked more open and dynamic than Sadangdaemun. In conclusion, traditional Korean space applies a monistic view of the world to nature and human beings, thereby embodying a philosophical and aesthetic space where humans enjoy their life in harmony with nature while playing with the landscape in a traditional space.

Recently, new functionally graded material(FGM) that has a spatial variation in composition and properties is developed because of its good quality. This material yields the demands for resistance to corrosion and high temperature in turbine blade, wear resistance as in gears and high strength machine parts. Especially coating treatment in FGM surface brings forth a mechanical weak at the interface due to discontinuous stress resulting from a steep material change. It often, leads cracks or spallation in a coating area around an interface. The behavior of propagation cracks in FGMs was here investigated. The interface stresses were reduced because of graded material properties. Also graded material parameter with exponential equation was founded to influence the stress intensity factor. And the resistance curve with FGM coating was slightly increased.

From the point of tectonic manner which is 'how to build a house' this study considers the characteristics of Kan in Hyangdan(香壇) at Yang-Dong Village. It was analysed with primary elements such as Kan, condition of a site, module, structural system, roofing system and their relationships in spatial and formal composition. Through the analysis, findings were achieved that characteristics of Kan to form a rectangle of 1 to root 2 proportion plan, enable irregularity in usage and regularity in compositional aspect and structural system to achieve intended roof design. In addition, Kan as a module is found to have a relative value that also regulates the whole in structural and aesthetical aspects.
