The purpose of this study is to understand how the silhouette changed throughout 1970s and assess how US women express their identities through their dress, which may explain societies' attitudes through the way women dresses. US Vogue fashion magazines were used to explore all the information on fashion and style trends, social trends, beauty, and travel. A content analysis was performed on the issues of the March and September for the years 1970 to 1979. The findings for this study about the 1970s were all about perpetual change, constantly moving forward with innovation. The color ranged from bright, cheery and bold to deep and passionate to subtle neutrals. There were a few constant colors through the decade like white, black and navy. Occasionally the trend would completely change from one season to the next within the same year. They would be full and oversized and then be slim and body conscious. The one trend that stayed true for the entire decade was wrapping. Skirts, pants, dresses, tops, shoes and jewelry; everything wrapped in one-way or another. Clothes steadily became more revealing as the years progressed. Fabrics over all were soft and knitted. Casual and comfortable was the phase heard most often. In the 1970s there was constant change in prints. They were bold and large or subtle and small, ethnic or floral. Hair was mostly smooth and sleek however towards the style moved to a fuller look.

This study looks into the change of the concept of museum and the programs as well from sociocultural point of view Since the very beginning in history, the museum has been a place to educate people with diverse evidences regarding on the human history by preserving legacies of the past. Throughout the long history, the concept of museum and its programs have been revised in accordance with social changes. Consequently, these changes brought the transformation of museums' roles nowadays. The reason is the public in diverse society are so accustomed to stimulus and dynamic cultural changes has induced those change in some senses. The study points that the variation of museum programs are to be developed and museum marketing strategies including global management of art museums should seriously be considered. It also brings new form of museum architecture. The concept of revitalizing museum can expand the band of public and provide them opportunities a place for various cultural activities which can lead a new trend in this society.

The problem of trend change in the failure rate is great interest in the reliability and survival analysis. In this paper we develop a test statistic for testing whether or not the failure rate changes its trend based on a complete sample. Monte Carlo simulations are conducted to investigate the speed of convergence of the proposed test statistic.

This study aims at finding the trend changes of spatial configuration in housing units of Korean apartments in the 2000s. Among the housing units in the apartments built by large construction companies, we have selected ones with small and regular sizes, $59m^2$ and $84m^2$ respectively, and investigated the number of bays, the location of wet zone and the spatial flexibility in the housing units selected for analysis. In conclusion, the number of bays in the housing unit has gradually increased, after allowing for the structural change of the balcony in the legal. It is estimated that the trend has came from the intent to increase the numbers of the externally exposed surfaces of the balcony, ensure a good view, lighting, ventilation and spatial flexibility. The location of wet zone, water-needed space such as a bathroom or a kitchen, has changed in the direction to facilitate the expansion and modification of space. Variable range of space has gradually expanded by using the balcony and wet zone as much as possible. In order to configure more effectively spaces in housing environments, the future study should be implemented to develop tools for realizing sustainable housing environment at the levels of not only the housing unit. but also the entire building, housing site, and city.

Precipitation is a crucial meteorological variable widely used as essential input data in most hydrological models. However, due to climate change, there is an escalating precipitation variability. Trend analysis plays an important role in planning and operating water resources systems. As recently developed, Innovative Polygon Trend Analysis (IPTA) is useful in identifying and and analyzing the trends of hydrologic variables. In this study, the IPTA was applied to monthly precipitation data obtained from 13 meteorological observatories in Jeolla province, along with synthesized precipitation data according to Shared Socioeconomic Pathways (SSP) scenarios. The trend results were compared those obtained from the Mann-Kendall test and the Sen's slope estimation which are generally used in practice. The results revealed monthly precipitations from February to July and November had increasing trends, and monthly precipitation in October had a decreasing trend. IPTA, Mann-Kendall test, and Sen's slope estimation detected trends in 75.00 %, 5.13 %, and 5.13 % of 156(13 stations × 12 months) time series of monthly precipitation, respectively, which indicates that the IPTA is more sensitive in trend detection compared to the Mann-Kendall test and Sen's slope estimation.

This study employs a structural time series method in order to model and estimate stochastic trend of surface temperatures of the globe, Northern Hemisphere, and Northeast Asia ($20^{\circ}N{\sim}60^{\circ}N$, $100^{\circ}E{\sim}150^{\circ}E$). For this study the reanalysis data CRUTEM3 (CRU/Hadley Centre gridded land-surface air temperature Version 3) is used. The results show that in these three regions range from $0.268^{\circ}C$ to $0.336^{\circ}C$ in 1997, whereas these vary from $0.423^{\circ}C$ to $0.583^{\circ}C$ in 2007. The annual mean temperature over Northeast Asia has increased by $0.031^{\circ}C$ in 2007 compared to 1997. The climate change in surface temperatures over Northeast Asia is slightly higher than that over the Northern Hemisphere.

The railway has been developed largely by the characteristic factors of the railway through change of the society and culture. The railway trends has been changing from instinctive methods to settle the mass transport of the early days, to sensitive methods to pursue the railway culture centering around human being. As dividing by period according to the changes of railway trends into the external nation, there are to analyze the development history of the railway design. Accordingly each nation (United Kingdom, Germany, France, Japan) and the style's change, to confirm the changes into the design applied in society and culture needs, and to analyze by a year in changes of the environment and the railway history from the 1800's to 2005, so there contribute in the development of railway design to present the paradigm of the future railway by analyzing the trend according to the changes of railway design and the life environment in this paper.

The relationship between temperature and apparent logarithmic hardness of ointments were clearly demonstrated. The followings were obtained as the results: 1. When the ointment base was mixed with additives and heated or cooled at various temperatures, the apparent logarithmic hardness in the first trend before reaching the critical point is subject to change mainly by the contents of the additive while in the secondary trend after reaching the critical point is subject to change mainly by the temperature. 2. No Change in the critical point was observed at different temperatures. It is assumed that the crittical point of such ointment bases has no relationship with temperatures and that the critical point itself should rather depend on the physicochemical properties of the additives.
