The purpose of this study is to analyse the inclinations and expressions in contemporary architecture. Specially, we call this tendency and architectural movements as architectural metamorphosis. Metamorphosis in architecture present the core of the change of Forms and spirits in a change of outward shape and terrestrial identity. As in Ovid's extended dramatic poem of change and transformation, Metamorphoses, all Souls are deathless, and migrates from one form to another. Like these stories in Metamorphoses, Ovid tells the soul never dies, but leaps one form to anther, and can take any shape. So the architectural form, transformation and deformation in contemporary architecture means architectural sensations and cognitions can even approach the soul of form and shape under the transformation. The expressions and design strategies of metamorphosis in comtemporary architecture reveal continuous and sequential formations of space, linear structure with force and vector, rhythmical wavement and folding surface, lively wiggly flows of volumns and objects, and so on. Such qualities came from the periodical needs; separation of structure and surface, poly-surfacial movement, poly-sensual expression and experience, dematerialization and the dematerialized space, formless of non-formal architecture, digital architecture. Architecture of Metamorphosis is the ways and the needs of our period to overcome the static limits prohibits the liberal thoughts, to find the ways toward the opportunities and diversities and to unlock the imaginaire of the contemporary architecture.

The pillar of the Paris Agreement, which will define the efforts of the international community against climate change since 2020, is the INDCs submitted by each country. In this study, the INDCs of the major industrial and developing countries (EU, USA, Japan, China, India) and South Korea are reviewed and national circumstances are analyzed based on the status of industrial structure, power mix and GHG emissions. We will also present South Korea's strategies in future climate change negotiations. South Korea should ; find out the special differentiating factors favorable to Korea with which the international community can agree; and establish an interagency working group to prepare for the periodical renewal of the INDC.

This study is based on the periodical discourse of women and their costumes, described in modern novels that were published from late 1890s to the 1930s. New cultural phenomena emerged among Korean women in the period of modernization. In particular, rapid increase of jobs for women and preference for western female body shape are very noticeable phenomena that can be observed in novels of the 1930s. In addition, the symbolic meanings of female costumes are variously described in modern novels according to the periodical and spatial environment and jobs for women. The symbolic meanings are organized as 'Trophysm, Expression of sexuality, Liberation from male-dominated society, Symbolic difference between rural and urban areas, Vanity, Decadence, Mechanism tending to hide and Change of values'. And women's costumes kept changing in the boundary of 'Confliction, Coexistence and Harmonization' of traditional and western costumes. 'Confliction' phenomenon got emerged in novels published between 1900 and 1910. The resistance on traditional costumes that restricted woman's life got spread. But western female costumes as a symbol of new culture could not be generalized but accepted as high fashion. 'Coexistence' phenomenon was appeared in novels of the 1920s. At that time, the modernization for traditional costumes by female students was emerged along with trendy fashion. Also, the frequency of using western fashion items was increased in the Korean society. Therefore, it shows that western costumes in the Korean society became popularized in the coexistence with traditional costumes. 'Harmonization' phenomenon was emerged in novels of the 1930s. In the novels, the emergence of western female costumes, personal preference items, and westernized hair style implies that western costumes were absorbed into the Korean society that had kept traditional costumes.

The aim of this study was to describe how the type of appeal and linguistic expression of men's wear advertisement in magazines by analyzing domestic men's and ladies' magazines published from 1990 to 1999. The periodical change in advertisement trend was also discussed. 1. Type of Linguistic expression The type of linguistic expression used in advertisements far men's wear could be classified into the following five categories : emotional expression, sensual expression, egoistic expression, informative expression, and brand name expression. The periodical trend in the use of each type of linguistic expression was as follows: the occupancy rate for the type of emotional expression was roughly 50 percent in the early 90's (1990-1993) and this percentage gradually decreased during the mid 90's (1994-1196) until the late 90's (1997-1990). Despite the decrease in occupancy rate, this type was the most commonly used. While the occupancy rate fur the type of informative expression gradually increased during the decade, occupancy growth fur the type of brand name expression was slight until its rapid expansion in the late 90's. The occupancy rate for the type of egoistic expression steadily increased during the early and mid 90's but decreased to its original percentage in the late 90's. As for the sensual expression, its occupancy was insignificant up to the mid 90's and then rapidly decreased in the late 90's. 2. Type of appeal The type of appeal used in men's wear advertisements could be classified into the four categories, sensitive appeal, sex appeal, image appeal, and quality appeal. The periodical trend in the use of each type of appeal was as follows: sensitive appeal was most commonly used during the decade ; it had an occupancy rate over 50 percent in the early 90's but the rate gradually decreased during the mid and late 90's. Sexual appeal were the least commonly used; though the occupancy rate increased during the early and mid 90's it dropped dramatically in the late 97's. The occupancy rate for image appeal gradually decreased until its growth in the late 90's. The occupancy rate fur quality appeal was insignificant in the early 90's. This percentage rapidly increased in the mid 90's but relapsed in the late 90's.

The change of the chemical structure of graphene oxide (GO) was investigated by periodical sampling of GO during exfoliation by using a sonicator. A significant amount of GO was exfoliated during up to 10 hr of sonication. Raman and Fourier transform infrared spectroscopy revealed a continuous increase of the G/D or C=C/C=O peak ratio of GO, as the sonication time increases. The photoluminescence (PL) intensity of each GO sample also decreased as a function of the sonication time. PL excitation spectra with three major peaks indicate that the sizes of $sp^2$ carbon clusters were enlarged by longer sonication. In addition, new excitation at around 300 nm proves the existence of newly developed small clusters of $sp^2$ carbons as the sonication time increased.

This paper presents the experimental study of drilling for duralumin A2024 with intermittently decelerated feed rate. It is achieved through a programmed periodic increase and decrease in the feed rate using a machining center. The following experimental result were performed with the objective of solving chip to disposal problems. In conventional drilling of aluminum, long continuous chips are produced that wind around the drill causing difficulties in eliminating chips from the cutting zone. In order to acquire the basic data necessary to regulate the chip profile, the relationship between cutting variables and chip shape was investigated. The following conclusions are established from the experimental results. At a suitable feed fluctuation ratio, intermittently decelerated feed drilling proved successful in breaking chips to appropriate lengths while maintaining stable cutting. Thus, it is an effective method for improving chip disposal. The amplitude of the dynamic component of cutting force in intermittent feed frilling is influenced by the feed fluctuation ratio.
