An optimal controller, e.g. LQG controller, may not be realistic in the sense that the required control power may not be achieved by existing actuators, and the measured output is not satisfactory. To be realistic, the controller should meet such constraints as sensor or actuator limitation, performance limit, etc. In this paper, the lnput/Output Variance Constrained (IOVC) control problem will be considered from the viewpoint of mathematical programming. A dual version shall be developed to solve the IOVC control problem, whose objective is to find a stabilizing control law attaining a minimum value of a quadratic cost function subject to the inequality constraint on each input and output variance for a stabilizable and detectable plant. One approach to the constrained optimization problem is to use the Kuhn-Tucker necessary conditions for the optimality and to seek an optimal point by an iterative algorithm. However, since the algorithm uses only the necessary conditions, the convergent point may not be optimal solution. Our algorithm will guarantee a sufficiency.

The purpose of this study is to compare a supposedly "pot boiler", Sanctuary and Sanctuary: The Original Text and examine the fact that Horace Benbow in The Original Text is a more complicated and many-sided character who has suppressed desire, Oedipus complex, sense of guilt for a long time, until he came to confront Temple-Popeye case. Since literary narration means unconscious procedure, Horace's incestuous love for his step daughter and Oedipal relation reveals Faulkner's own psychology. In this sense, The Original Text serves as a matrix of many of Faulkner's major novels in terms of themes, characters, and the relationship between past and present. Among these novels are The Sound and the Fury, As I Lay Dying, and Flags in the Dust. Faulkner, while writing about his own world creating Yoknapatawpha County, tries to portray characters with artistic value through whom he wanted to express the deep anxiety and turmoil of the 1920s. Starting with Horace Benbow, Quentin Compson, Darl Bundren and young Bayard Sartoris can be doubling through his major works, conveying author's profound despair in the context of modern world.

In the period from the year 1500 to 1980. at least 14 large earthquake with epicenters in the northeastern China and Yellow Sea were felt or destructive in the Korean Peninsula. The most sigmificant events among them were the 1668 July 25 Tancheng earthquake of mamnitude 8.5, and the 1975 Feb. 4 Haicheng earthquake of magnitude 7.3. The Haicheng earthquake of the year 1975 in am extraordinary one among those occurred in the northeastern China in the 20th century in the sense the Shake of the event affected all over the Korean Peninsula. The tremor was felt even at the southeastern tip of the Korea and northern part of Kyushu 700km far away from the epicenter. In order to see the variation and trend of the effect of the Haicheng earthquake on the Korean Peninsula, the two data sets of the northern and southern parts of the peninsula were merged into one combined data set. The spatial variation of intensity shows smooth decrease from the value 4 of the northwestern region near the source to the value 1 of the Cheju Island and Kjushu. However, there are four regions of locally high intensity value. They are the region along downstream of Abrok(Yalu) River with intensity 5, the region around Shinpo of intensity 4, the area comprising Seoul and Chuncheon Cities of intensity 4, and Pohang-Pusan area of intensity 3. We suppose that there might be three types of possible mechanisms. The first one is concerned with the lateral inhomogeneity of velocity in the crust caused by wide distribution of relatively fractured rock. The second one is related with reflections of surface waves caused by the crestal thinning effect at border regions of the Peninsular in contact with the Ulleung Basin and the Japan Basin. The third possibility is local site effect caused by thick Tertiary or Quaternary rocks and soil layers.

Cultural sensation by appearance of Elvis Aaron Presley is thought to have been greatly influenced by spread of popular culture beginning to form with the development of mess media in USA that was changed rapidly after the war, changing aspect of popular music in U.S.A through the media development and teenager culture of USA that has rapidly emerged. Elvis intended to change into 'music to be seen' deviating from 'music to be simply listened to' with expressing the conversion of sexual consciousness, defiance to older generation and a sense of value on wealth, and the like, and also suggested a new culture and style to the young people at that time. Flow of Elvis's fashion may be categorized into the classifications such as the fashion in the period. First, Formative period(before 1954) distinguished by pimp look and sideburns with tough image and wild clothes. Second, Establishment period(1954-57) may be categorized into the hot rockabilly style which showed a glittering fashion by brilliant and colorful costumes, the cool rockabilly style which changed him to a fashionable star of modem image(1958-60). Third, re-heyday(after 1968) where a brilliant and bold decoration was displayed. In Elvis fashion, the masculine sensualism, defiance to main value and expression of luxury and consuming culture, etc. are included as a unique aesthetic consciousness. 'Expression of masculine sensualism' represented the sensualism through sexual objectification of men's body by men's sexual ostentation which was prohibited. 'Defiance to main value' means that attempts of non-mainstream image for social class are expressed with an exercise of power by young people through the public. Although the Elvis look has fanned an anti-culture, it was expressed and accepted as having a normally capitalistic appearance. In addition, it being thought of as the standard, symbolizing a success and a wealth through the presentation of image which accepted this material benefit, we may classify this into 'expression of luxury and consuming culture'.

Using the official marker of the Korea's national symbol to inform the world of the country's existence to the global community in the $21^{st}$century enhances the autonomy and the competitiveness of Korea. It is thought that selecting a motif for promoting the national identity through cultural products or costumes can prepare an opportunity for gaining competitiveness internationally. The purpose of this study is to enhance understanding on the use of a traditional Korean symbol, Mugunghwa, and how it increases the cultural value of Korea, and develops the modern Korean image. The specific contents of this study are as follow. First, searching for the scope of usage of the national flower Mugunghwa from various angles for enhancing the Korean image. Second, developing a national symbol image of modern sense that reflects trend by using Mugunghwa. Third, clarifying the application scope and role of the national symbol image using Mugunghwa, and present a specific usage plan for creating more value. As for the study method, the study is conducted through theoretical and empirical research and six pieces of work of modern Mugunghwa image are presented as the result. Based on the development of the image of Mugunghwa as a national symbol, this study proposed a role of a cultural ambassador by applying Mugunghwa to fashion products or costumes. As for the expected effect, it can provide an opportunity for developing another national symbol and a new perspective on national symbol will appear. It is thought that the cultural value of a national symbol can be understood through this study and it can provide an opportunity for developing various national symbols for enhancing the national image.

Theoretically, it is said that economies of scope can be realized in the cropelivestock cycling organic farming. Thus, it is also used as the principle of organic farming. However, it is difficult to find the cases of the empirical analysis of it in Korea. In that sense, this study is meaningful in that it analyzed the agricultural data of case farms of obtaining the approval of both organic agricultural products and organic animal products and practicing cycling farming for 4 years and tested the hypothesis. This study measured economies of scope by using the actual measurement value and estimation value farming performance statistics for 4 years of case farms. This farmhouse conducted nutrient cycling in the farm like self-manufacturing and injecting organic agricultural byproduct and wild grass as organic livestock feed and fermenting organic livestock manure to organic compost to return it 100%. The results can be summarized as follows: According to the result of cycling farming of combining and producing organic agriculture and organic livestock, economies of scope were found to be realized in this case farmhouse. That is, although not strong, EOS>0, there were economies of scope. The measurement value appeared as 0.0722, 0.00378, 0.04667 and 0.13127 in 2012, 2013, 2014 and 2015, respectively. It was improved as time passes and the scale gets smaller. Therefore, in order to further improve economies of scope, there should be measures of reducing duplication costs between agriculture-livestock as low as possible and lowering the production cost of organic feed. That is, there is a need for the management strategy to adjust the import function and cost function according to the change in management paradigm and cropping system.

As the design of the day focuses more on human-centered design, this shift creates value for society and also fulfills on a sense of social responsibility. In the area of fashion, the design activity is used as a type of fashion design to realize the social value of design in a changed society; this concept was defined as Fashion Design Activism. The objective of this study is to empirically research design activity as a practical value of the day when the social contributions of fashion design are rising in the overall society through the research on the practice of Fashion Design Activity which is adapting to changes in the fashion design paradigm. Regarding the study method, the literature research and case study were combined. We examined the meaning of social design by reviewing the literature related to this social paradigm, and we analyzed cases in which the effects of fashion design on society were realized through practical activities. Also, we defined the role of fashion design based on an analysis of design types based on previous research. This study divided the roles of fashion design in a pattern based on the social roles that design inhabited, in terms of how 'fashion design fulfilled on social responsibility', 'anthropocentric fashion design putting emphasis on users', and 'fashion design aiming for eco-efficient changes'. This study aimed to seek measures to develop fashion design that could promote changes focusing on society, humans, and the environment.

This study aims to get basic data for an objective searching examination into the value of household production through grasping the relation between homemaker's consciousness or attitude on it and the socio-economic related variables in today, the economic period of currency exchange. the approach of this study depends on the consultation of concerned references and social survey by questionnaire to explore the homemaker's consciousness. Homemakers with children over six years old were selected as object and stratified, considering each age of them and variety of socio-economic status. 450 homemakers among 600 selected with collecting the data. But only 353 samples are helpful for this analysis. They were calculated by frequency, percentage and the mean value for general characteristics of the families, and the noteworthy degree applied the Chi-square(x2) was measured to investigate the correlation between the related variables and each of items. The data was treated by the SPSS program of Computer Center, Korea Science Institute. The conclusions of this study are as follows; 1) The majority of homemakers have had affirmative consciousness on the household production as well as strong sense of responsibility in doing their duties. But the higher educational background or the standard of living are, the more want they to have a job also have a tendency to have leave the household production to others. 2)The reason that housemaker does not have a job is for being faithful to home life. But the higher educational background she have, the more weight is given to the management such as to husband or to children card, than to household affairs. 3) Homemaker's educational background and experiences in job affect on her spirit of inquiry for rationalization of the household production and social compensation mentality, by having more strong needs of learning for the household production or of socially proper compensation for casualty. 4) Homemakers mostly have affirmative consciousness on division of household affairs, that they think in need to feel the family as one body among themselves and to cultivate co-operative mind.

This study focuses on the genealogical analysis of the urban public spaces by the local history of Seoul which is significantly different from western cities. The analysis targets the discourse of the urban street which defines urban space-structure among the urban public spaces. Based on the analysis, we define the progress levels of urban public design policy in Seoul. Firstly, in 1960's and 1970's, 'urban reconstruction' was intensively carried out for the country modernization, and 'vehicle preferred street expansion' resulted in damages to historical inheritance, in-humanized street, and cultural uniformity. 1980's and 1990's would be defined as 'politic acceptance of plural values to the urban street.' There were the Olympic Games held in Seoul in 1988, which were the celebrations of the 600th capital establishment and the autonomous local government system. In the meanwhile, diverse values on the urban street were discussed in terms of globalization. There also were the self-reflection for the urban skyscrapers and high-population rate, the cultural uniformity of urban street, and the commercialization in downtown with urban reconstruction plans. Then, the sense of landscape and amenity was focused. Various urban projects and regulations were held according to the changes of value recognition. 2000's can be defined as 'introduction to the organic integration and the urban public design governance.' In the 21st century, types of recognition have changed significantly, which include publicness, humanism, sustainability, symbolism, artistry, placeness, and communication. They cause the establishment of ordinances and the installation of integrated organization via urban design administration. The legislation has been revised in order to support the various methods for the maintenance and operation of urban landscape in terms of local characteristics. New regulations were established for residents to participate in the processes of the urban planning with street design policy.
