As a part of Avant-Garde movement centered in Russia before and after the Revolution in 1917, Russian Constructivism was born as most experimental and avant-garde modernity artistic movement. Russian Constructivism played a significant part in relative to Avant-Garde in the beginning of twentieth century and has contributed to a series of artistic movement, it deserves a status befitting its contribution to modem abstract art. Noticing the fact that Constructivist approaches are being attempted in modern architecture with the new rise of Constructivist design theory and increased interest in Constructivism, this thesis explores the design elements characterizing Constructivism in art and architecture To be specific, it suggests the relation of Plastic paradigm in formalistic, elemental and technical aspects and categories into Plastic characteristics. Thereby, the thesis aims to categorize the elements in terms of contradicting two trends of pure plastic and scientific expressions, and to analyze comparatively the related Plastic trends represented in modern space design. The thesis recolonizes that attempts to break out from stereotypes of Constructivism to reinvent itself constantly have contributed to an unconventional forms and new aesthetic standards and have a great impact on idealistic forms in many genres.

This study was carried out to investigate the occurrence and characteristics of off-type rice plant according to agronomic conditions. The occurrence density of the off-type rice plant in farmer's paddy field was greater as the years of self-produced seed use increased, and in the direct sowing paddy field it was twice as much as in the transplanting paddy field. When the long-grain red rice and the short-grain red rice in the cultivated field of cultivar were artificially sown, in the direct sowing on a flooded paddy surface culture rather than in the machine transplanting culture the off-type rice plant occurred much more, the culm length was longer, and the number of productive culm per plant increased. These characteristics were more conspicuous in the long-grain red rice than in the short-grain red rice. In the transplanting farmer's paddy fields, the off-type rice plant that occurred outside of the hills of the cultivar rice ranged 0 to 6%. Whereas in was 70.6 to 91.9% when the long-grain red rice and short-grain red rice were artificially sown. Therefore, it was assumed that most of the off-type rice plants occurred in the farmer's paddy fields was caused by seed contamination.

By analyzing the characteristics and meaning of dystopia in Korean juvenile science fiction, this study aims to search for the principles of juvenile literature responding to the contradictions of scientific technologism in collusion with state capitalism, and to consider its limitations and significance. This study focuses on the juvenile science fiction in which children or teenagers fight against system dystopia functioning as a setting of the story. System dystopia consists of 'fake utopia' and 'concentration camps' holding those excluded from this 'fake utopia'. Young people whose right to life are violated under the system dystopia escape from concentration camps and fight against political power. We don't have many novels that have focused on environmental dystopia, but a nomadic subject is found in works set on Earth after environmental pollution or nuclear explosion. In short, juvenile dystopia science fiction deepens the contradictions of the hierarchical society based on scientific technologism, criticizing the repressive, material-oriented and differential educational realities of our society. They hope that children or teenagers will act as a resistance that sees through the deception and hypocrisy of the social system. These works are significant in that they expose the biopolitics strategy of political power in collusion with industrial capitalism and induce us to reflect on it. However, it seems to be the limit of humanism to equate human life with nature and to warn of dangers of technology, machinery, and material civilization as the counterpart. This paper has the significance of taking a general survey of juvenile dystopia science fiction since the 2000s, and revealing the writers' perception of scientific technologism and its limitations.

Recently a variety of study of Korean parsing system is carried out by many software engineers and linguists. The parsing system mainly uses the method of machine learning or symbol processing paradigm. But the parsing system using machine learning has long training time because the data of Korean sentence is very big. And the system shows the limited recognition rate because the data has self error. In this thesis we design system using feature module which can reduce training time and analyze the recognized rate each the number of training sentences and repetition times. The designed system uses the separated modules and sorted table for binary search. We use the refined 36,090 sentences which is extracted by Sejong Corpus. The training time is decreased about three hours and the comparison of recognized rate is the highest as 84.54% when 10,000 sentences is trained 50 times. When all training sentence(32,481) is trained 10 times, the recognition rate is 82.99%. As a result it is more efficient that the system is used the refined data and is repeated the training until it became the steady state.

In this paper, correlation analysis was performed between questionnaire and machine learning based aggressive tendency measurements. this study is part of a aggressive driver detection using machine learning and questionnaire. To collect two types tendency from questionnaire and measurements system, we constructed experiments environments and acquired the data from 30 drivers. In experiment, the machine learning based aggressive tendency measurements system was designed using a driver behavior detection model. And the model was constructed using accelerate and brake position data and hidden markov model method through supervised learning. We performed a correlation analysis between two types tendency using Pearson method. The result was represented to high correlation. The results will be utilize for fusing questionnaire and machine learning. Furthermore, It is verified that the machine learning based aggressive tendency is unique to each driver. The aggressive tendency of driver will be utilized as measurements for advanced driver assistance system such as attention assist, driver identification and anti-theft system.

The satirical content of the absurd play, centered on Lee Keun-sam's play, represents the family image of a modern capitalist society where only duty is emphasized while the characters are lost in love with the family. They show humans becoming subordinate to economic logic as traditional relationships and family relationships change into material ones due to the rapid development of the economy. The narrator expresses the roles of the performer and the narrator together. It also presents the plot as a characteristic element of epic and absurd dramas, and directs actors as directors. It also foretells the events that will take place in the future, presents the inner consciousness of the characters in the play, and reduces and expands events and times. In terms of conflict, in order to fulfill the financial responsibility of their children, the professor translates them like a machine and the wife distributes the money they earn as they demand. The middle-aged professor and his wife are not willing to make a difference in the real world, so specific conflicts are not revealed. Therefore, no concrete conflict appears within this work. The plot of consisted of 22 epicentre compartments, consisting of a time frame from evening to the next morning. And no special events happen and show only one family's daily life. In addition, materials that show simple repetition of daily life such as newspapers, rice, birthdays, etc. are effectively showing the character of absurdity through repeated structure. The linguistic features of the absurd play focus on expressing anxiety, despair, fantasy and the sense of loss that the object's purpose has disappeared. The stage system avoids detailed portrayals of naturalist plays and creates a thoroughly simplified image that the theme of the play demands, which shows that the stage unit is also an important element that characterizes the absurdity of reflexes.

The suppression of fluid force acting on a square prism near plane wall was studied by attaching fences on the corners of the prism. The height of the fence was 10% of the square width and the range of Reynolds number considered was Re=$2.0{\times}10^4$. The experimental parameters were the attaching position and numbers of fences, the space ratios G/B(G/B=0.1${\sim}$1.2) between prism and plane wall. The average drag coefficients were increased and the average lift coefficients were decreased and increased with the space ratios toward plane wall. The drag of the prism was reduced average 7.6% with the space ratios by attaching the normal fence at the rear and upper corner and the horizontal normal fence at the rear and lower corner on the prism. In this case, the separated flow at the front and upper corner was reattached on the upper side of the prism and the vortex streets between the prism and plane wall were appeared more slowly than that of prism without fences.

The design process of the motor driven tilt/telescopic steering column is established by axiomatic design approach in conceptual design stage. By selecting independent design variables for improvin g performance of the steering system, each detailed design can be carried out independently. In the detailed design, the safety in crash environment and vibration reduction are considered. An occupant analysis code SAFE(Safety Analysis For occupant crash Environment) is utilized to simulate the body block test. Segments, contact ellipsoids and spring-damper elements are used to model the steering column in SAFE. The model is verified by the result of the body block test. After the model is validated, the energy absorbing components are designed using an orthogonal array. Occupant analyses are performed for the cases of the orthogonal array. Final design is determined for the minimum occupant injury. For vibrational analysis, a finite element model of the steering column is defined for the modal analysis. The model is validated by the vibration experiment. Size and shape variables are selected for the optimization process. An optimization is conducted to minimize the weight subjected to various constraints.

Through the 20th century architectural theory of rational thinking and the principles according to the statement of the firm, Le Corbusier's early works by analyzing the language of architecture, including his architectural concepts and helps the understanding of modern architecture. Masters of modern architecture as a place among the works of Le Corbusier in the 1920s, 'Le Corbusier's White Period' homes to target by age, and that his initial concept of the formation process of clarifying, further the construction of his golden age will be the key to understand. I selected housings from Maison Citrohan to villa Savoye, the category of architectural elements by considering the development process, he examines developments of the concept of modern architectural space. In analysis process, First of all, I am focused on between each element in the development process to review and explicate the integration process. The advent of the machine which he lived, because of its incredible potential reorganization of human society, as well as to celebrate the start of a new lifestyle. His architectural language of the times in the machinism could achieve progress and modern art, which is a new interpretation of the natural world.

Fine wires made from platinum have been used as sensors to evaluate the convection performance of nanofluids. However, the wire sensor is difficult to handle due to its fragility. Additionally, an unrealistic convective heat transfer coefficient (h) is obtained if a rigorous calibration process combined with precision equipment is not used for measurement. This paper proposes a new evaluation apparatus for h of nanofluids that uses a thermistor sensor instead of the platinum wire. The working principles are also explained in detail. Validation experiments for pure engine oil comparing h from the two sensors confirmed numerous practical benefits of the thermistor. The proposed system can be used as a useful tool to justify the adoption of developed nanofluids.
