The purpose of this study was to analyze the characteristics of the Junk Art represented in the second half 20the century fashion. The highly developed material civilization resulted in human alienations environmental distruption. By this fact human being of the 20the century was to overcome social com-plexity. In this respect this research was focused that how the characteristics of the junk Art was expressed in the second half 20th century fashion. The concepts of the Junk Art lied in the creation of art work in the 2-dimentional plane of 3-dimentional space through the application of all junks (wood pieces industrial debris trash ready-made goods etc) cast by the mod-ern industrial society and the mass production system. Juck Art had been further envigorated in the footstep of the development of the collage method based on the creation of object aes-thetics. And junk artists have untitled social environments with art by assembling junks as a way of exploring the material world of cur-rent society and provided infinite possibilities of expressional medium and technique. Above all junk Art has been reflected in the fashion as well as other art. Especially a lot of the fashion design by the use of junks and the expressive image of junks is produced in the 20th century. That is many of fashion designers have always been aware of what is happening in the arts and have always been able to use the dis-coveries and ideas of the artist to help them solve design problems and creat fashion which are new inventive and reflective of their time. The fashion designers of the junk fashion design could be said to have presented much more possibilities and new development for-mulas to modern fashion design and provided a new order of other formative arts. Unlike the negative and destructive punk cyberpunk fashion junk fashion was a positive and optimistic aesthetics. junk fashion that keeps pace with science and the development of technology is devoted to trying to grasp the real form of ultimate re-ality.

Uymsikdimibang(음식디미방) - a book written around 1670 and implying the methods of understanding the taste of food and drink - records many kinds of alcoholic drinks. it is obviously a practical problem to explain the process of brewing alcoholic drinks. However, if we intend to approach the alcoholic drinks on the practical aspect, we can not explain why many kinds of alcoholic drinks were brewed. I acknowledge only that it was true to have brewed rice wine easily on the basis of the increase of the production of rice and the two-crop farming system of rice and barley in a paddy field as well as, for many kinds of alcoholic drinks to have increased as a result of the development of brewage since the middle and second half of Chosun. It is not until we approach the alcoholic drinks of those days on the level of meaning, value, and symbol that we can get a correct answer as to why Uymsikdimibang records many kinds of alcoholic drinks. In the second half of Chosun, confucian ideology was firmly established in country village societies, the idea of clan rules was instituted, and patriarchal system was organized. Such a social atmosphere was to emphasize the practice of confucian moral principle such as performing religious service on one's ancestors and receiving a guest, and in the course of it, the alcoholic drinks were recognized as important materials all the more. It seems that the subdivision and elaborateness of the meaning of the alcoholic drinks were in progress. As a result, I think that the alcoholic drinks would vary in kind and be graded. From ancient times, the alcoholic drinks were men's favorite foods, and the significance of the authority and prestige given to the alcoholic drinks was increasingly promoted by the rise of the social position of men in the second half of Chosun under the influence of confucian ideology. Subsequently, the alcoholic drinks became symbols which represented even the family's tradition and dignity. Therefore, men born of the nobility(Yangban) tried to brew the various and dignified alcoholic drinks relatively. Through the brewage such as this, they endeavored to maintain their privilege. I think that the diversification of alcoholic drinks was developed in the process of a series of social-institutional change.

The purpose of this study was intended to analyze mechanical beauty of the art style represented on the second half of the 20th century fashion. From the early 20th century, when the mechanical civilization began to develop in full scale, various distinctive styles of art began to emerge by the denial of the traditional artistic style, which is said to be an inevitable consequence fo the 20th century's spirit. That is, the diversified styles of modern art, which has developed in line with the rapid growth of civilizations, experienced environmental pollution, non-humanization and un-individualization. Those phenomena became mental anguish for artists and designers, they have come to meet with changes, by their efforts to find new way. SO, the mechanical beauty is becoming a very important factor arts. Especially, the collage of the Cubism have used as art techniques of positive mechanical beauty. And in the transition from Dada to Surrealism, the objects provided an important harmony, suggesting that all things, even those achieved by chance or presented in new associations or radical dissociations, could be said to have meaning. Pop Art that expressed daily living of spending culture in the post industrial society, scaled up the induction of mass media which was much more realistic than Dada or Surrealism. According to the results of this study, the second half of the 20th century fashion has generated mechanical beauty was examined and plundered by modern art styles. The mechanical beauty of modern art was represented in the modern fashion as the positive and negative formativeness. Above all, the best way that the fashion design should take in the future, is in the search of ways how to restore humanity that was lost due to use of machine, how t develop its merits and how to harmonized with mechanical civilization.

The purpose of this study is to produce slacks pattern for pregnant women in the mid or second half period of their pregnancy according to the development figure of the body shell from a follow-up measurement. We here would like to produce slacks pattern for pregnant women constructed to fit better with their individual property in their figure and to help maintain the shape and beauty of the lower half of body and would compare it with two manufactured slacks pattern. The results of the study were as follows; 1. As the pregnancy proceeds, the height of natural-waist line went up spontaneously due to the projection of abdominal region, therefore, it was given darts at the front zipper part so that they could maintain a nice figure and to avoid possibility of feeling oppressed. To acquire a slimmer outfit, we made of the slacks-bottom narrower than the width at the knee line, and it worked out. 2. Sensory evaluation for appearance: According to the statistical of the result of 19items on the questionaire, all items showed significant difference(a$\leq$0.01) between the new and A(bunka) B(Kim's pattern) method slacks pattern, with the new pattern having higher scores. The new drafting method proved to be better fitted, to fit the shape of bodies properly and to get a visual effect to look slim.

This study investigated the association between the expenditures for childrearing and the intention to have the second childbirth applying the recursive equation models. The major results were as follows. First, more than half of the households with one child did not have an intention to have the second childbirth. Second, about 40% of the household expenditure was spent for childrearing. About 36% of the childrearing expenditure was spent on the childcare and education, and about 64% on purchase of goods and services for child. Third, the variables which had a significant effect on the intention to have the second childbirth were child's age, mother's education, father's income, the private educational expenditure, and consumption expenditure for child. The intention to have the second childbirth did not have a significant effect on the level of childrearing expenditure. The implications for the family policies were suggested.

This paper considers the problem of regulating the output voltage of a current doubler rectified asymmetric half-bridge (CDRAHB) DC/DC converter via fuzzy integral control. First, we model the dynamic characteristics of the CDRAHB converter with the state-space averaging method, and after introducing an additional integral state of the output regulation error, we obtain the Takagi-Sugeno (TS) fuzzy model for the augmented system. Second, the concept of parallel distributed compensation is applied to the design of the TS fuzzy integral controller, in which the state feedback gains are obtained by solving the linear matrix inequalities (LMIs). Finally, numerical simulations of the considered design method are compared to those of the conventional method, in which a compensated error amplifier is designed for the stability of the feedback control loop.

In this paper, we consider maximum likelihood estimators of the location and scale parameters for the half-logistic distribution when samples are multiply Type I hybrid censored. The scale parameter is estimated by approximate maximum likelihood estimation methods using two different Taylor series expansion types ($\hat{\sigma}_I$, $\hat{\sigma}_{II}$). We compare the estimators in the sense of the root mean square error (RMSE). The simulation procedure is repeated 10,000 times for the sample size n=20 and 40 and various censored schemes. The approximate MLE of the second type is better than that of the first type in the sense of the RMSE. Further an illustrative example with the real data is presented.

In this paper, Takagi-Sugeno (TS) fuzzy integral control is investigated to regulate the output voltage of an asymmetric half-bridge (AHB) DC/DC converter; First, we model the dynamic characteristics of the AHB DC/DC converter with state-space averaging method and small perturbation at an operating point. After introducing an additional integral state of the output regulation error, we obtain the $5^{th}$-order TS fuzzy model of the AHB DC/DC converter. Second, the concept of the parallel distributed compensation is applied to design the fuzzy integral controller, in which the state feedback gains are obtained by solving the linear matrix inequalities (LMIs). Finally, simulation results are presented to show the performance of the considered design method as the output voltage regulator and compared to the results for which the conventional loop gain method is used.
