The rapid increase in apartments of Korea brought about overall changes in the life style, and definitely played the biggest role to convert into western style. Since 1960, furniture has been changed for 50 years along with apartments, but furniture companies and the academic world had insufficient historical materials and lack of study. In addition, considering the changing trend according to residents' life style, the data of furniture industries should be collected to study every year or in 5 years at least. Therefore, this study aims to provide basic data that gives historical materials or design clues based on recent AV equipment-oriented storage furniture in the living room that prioritized design in public space. Accordingly, the study looked into the periodical trends of Korean furniture industries, analyzed 10 furniture companies in Korea which is actively doing business as the sample and arranged key points of periodical changes of furniture in the table, and suggested the conclusion according to the image map, style, color, material, and function.

This thesis is focused on the visitors varied experiences of the current museum architecture. The current trend and periodical development of visitors experiences are discussed by analyzing the factors such as the external symbol scheme, the exhibition space scheme, and the visitors circulation scheme which are involved with a visitors experience and thus classifying the experiences related to each sample museum. Examining and providing logical descriptions on each of the schemes helps comprehend the visitors varied experiences. This research, which deals with thoroughly understanding a museum as an architecture followed by taking visitors experiences into account, is aimed to contribute to improving visitors experiences in the course of designing a museum. The above-mentioned types of combination applied to each museum chosen for the research help understand the following : National museums show predominance of specific visitors experiences. As for the external symbol scheme, most of national museums have adopted the temple type, whereas international museums have equally adopted with the temple type and the showroom type which are characterized by its dedication to function and being in balance between contents and formalities.

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.

In this paper, To estimate monthly water distribution volume required optimization control of operating scheme & water distribution management for water transmission system in water supply, both Thomas-Fiering technique and Fourier series are compared and analyzed, respectively. Since water distribution volume is periodically repeated and has a linear fluctuation trend, parameters in each element are estimated through dividing into linear fluctuation trend component and periodical component. Finally, results of time-series analysis are proved to be more reasonable than that of Thomas-Fiering techniques by comparing simulation with observation data.
