$21^{st}$ century customer is voluntary actor, who has hegemony of communication based on digital surrounding. They are co-creator dismantling boundary between production and spending, and digital homonarrance of digital storyteller acting on the emotion. What is more, they prove the utility of 5 sense, value, experience, and story in market. 20th century Me generation is changing into We generation, who overcomes a sense of alienation and aim at smart life style for harmonious symbiosis with earth environments. Customer cultural trends are as follow as that 1) personalization of taste and experience, 2) spreading and sharing about personal use and experience, 3) consumption centered the value, 4) retreat and healthcare, 5) counter trend comes into the reaction about the forceful major trend. Contemporary customer changes essence of the life on the ground of emotion, symbol, image, and value not a commodity, function, and logos, and demands into change about direction of business to mostly enterprises. Customer's need and desire are on the increase as various emotion and value. Therefore, change of customer cultural trend is barometers for the growth and development of new fashion industry in $21^{st}$ century.

지구온난화로 인한 기후변화에 관한 연구에 따르면, 최근 지구온난화의 징후가 매우 뚜렷하며, 강우의 강도는 증가할 것으로 예측되고 있다. 매해 발생하는 극한수문사상으로 인한 피해가 꾸준히 증가하고 있는 추세이며, 증가하고 있는 집중호우의 발생 빈도는 강우자료의 추세에 분명히 영향을 미치고 있다. 현재 수자원 계획이나 설계에 수행되고 있는 확률강우량 산정법은 강우자료가 정상성을 지니고 있다고 가정하여 빈도분석을 실시하고 있다. 이러한 정상성 확률강우량 산정방법은 최근의 관측강우의 증가 추세를 반영하지 못하여 기후변화에 따른 이상강우에 매우 취약할 수 있다. 본 연구에서는 강우시계열에서 나타나는 경향성의 시간적 변동 분석을 위해 현재 경향성이 나타나지 않는 강우관측소 51개 지점에 대하여, 강우 관측자료가 가지는 통계적 특성을 유지하면서 추계학적 시계열 모의발생기법을 이용하여 강우자료를 발생시킨 후 경향성 검정을 실시하였다. 그 결과 대상지점 51개 중 13개 지점에서 향후 10년 이내에 경향성이 나타나는 것을 확인할 수 있었다. 이는 강우의 변동 추이가 현재와 같이 계속 진행된다면, 비록 현재에는 정상 시계열로 판단되는 강우 시계열일지라도 향후 비정상성을 갖게 됨을 반증한다. 따라서 목표연도의 확률강우량을 산정할 경우 강우의 증가 경향성을 충분히 반영할 수 있는 비정상성 확률강우량 산정 방법이 적용되어야 할 것이다.

The changes in thermodynamic and dynamic aspects on near (2025~2049) and long-term (2075~2099) future climate changes between the historical run (1979~2005) and the Representative Concentration Pathway (RCP) 4.5 run with 20 coupled models which employed in the phase five of Coupled Model Inter-comparison Project (CMIP5) over East Asia (EA) and the Korean Peninsula are investigated as an extended study for Moon et al. (2014) study noted that the 20 models' multi-model ensemble (MME) and best five models' multi-model ensemble (B5MME) have a different increasing trend of precipitation during the boreal winter and summer, in spite of a similar increasing trend of surface air temperature, especially over the Korean Peninsula. Comparing the MME and B5MME, the dynamic factor (the convergence of mean moisture by anomalous wind) and the thermodynamic factor (the convergence of anomalous moisture by mean wind) in terms of moisture flux convergence are analyzed. As a result, the dynamic factor causes the lower increasing trend of precipitation in B5MME than the MME during the boreal winter and summer over EA. However, over the Korean Peninsula, the dynamic factor causes the lower increasing trend of precipitation in B5MME than the MME during the boreal winter, whereas the thermodynamic factor causes the higher increasing trend of precipitation in B5MME than the MME during the boreal summer. Therefore, it can be noted that the difference between MME and B5MME on the change in precipitation is affected by dynamic (thermodynamic) factor during the boreal winter (summer) over the Korean Peninsula.

Recently major construction companies are building Housing Cultural Center instead of existing model house or housing gallery for accomplishing new marketing strategy. This Housing Cultural Center are different with existing model house or housing gallery on scale, spacial composition and operating program. And Background of differentiation is caused by change of housing market's environment, consumer's awareness level, service and marketing strategy. Because existing model house or housing gallery can not supply various consumer's needs and change of awareness level. Therefore, recent Housing Cultural Center is focused on cultural marketing for rapidly adjusting to new customer's need, including new customer acquisition and old customer retention. In accordance with this situation, it is very important to analyze out type and trend of Housing Cultural Center as facility for enlargement of cultural service and companies's social role for consumer. Therefore, the purpose of this study is an analysis about the trend of Housing Cultural Center as cultural space and a presentation of concept, function and direction when other construction companies build Housing Cultural Center hereafter.

Temperature increase due to climate changes causes change of water temperature in rivers which results in change of water quality etc. and the change of river ecosystem has a great impact on human life. Analyzing the impact of current climate changes on air and water temperature is an important thing in adapting to the climate changes. This study examined the effect of climate changes through analyzing air temperature trend for Nakdong river basin and analyzed the elasticity of air-water temperature to understand the effect of climate changes on water temperature. For analysis air temperature trend, collecting air temperature data from the National Weather Service on main points in Nakdong river basin, and resampling them at the units of year, season and month, used as data for air temperature trend analysis. Analyzing for elasticity of air-water temperature, the data were collected by the Water Environment Information system for water temperature, while air temperature data were collected at the National Weather Service point nearest in the water temperature point. And using the results of trend analysis and elasticity analysis, the effect of climate changes on water temperature was examined estimating future water temperature in 20 years and 50 years after. It is judged that analysis on mutual impact between factors such as heat budget, precipitation and evapotranspiration on river water temperature affected by climate changes and river water temperature is necessary.

The purpose of this study was performed to analyze the trend of bodytype change of adult males. Subjects were 1290 Korean adult males and their age range was from 19 to 54 year, ; old. 75 variables(66 variables from the direct anthropometric data and 9 variables from the multiplication method) in total were applied to analyze. The principal component analysis was applied to the data with orthogonal rotation after extraction of major factors. The high factor loading items extracted by factor analysis were analyzed for the trend of bodytype change by the age group respectively. The result of factor analysis indicated that the first factor was composed with about 30 items, girth, depth and width-measures in 4 age groups and was analysed as form factors. Especially, age-related change was caused by increase of waist girth, depth and width. The second factor was composed with about 23 items, length and height-measures in all age groups. Stature has a constant factor loading value in 4 groups. Front and back waist-height and the navel-height have the highest factor loading value. The third, fourth and fifth factors were composed with different variables among the age groups.

A Gaussian smoothing algorithm obtained from a cascade of convolutions with a seven-point kernel is described. We prove that the change of local sums after applying our algorithm to sinusoidal signals is reduced to about two thirds of the change by the binomial coefficients. Hence, our seven point kernel is better than the binomial coefficients when trend curves are needed to be generated. We also prove that if our Gaussian convolution is applied to sinusoidal functions, the amplitude of higher frequencies reduces faster than the lower frequencies and hence that it is a low pass filter.

As fashion is a reflection of a way of life, jean fashion seems to be a reflection of the background and process of social-human psychology. Modern jeans reflect personality and trend rather than traditional practicality as indicated by the concept and emphasis of fashion. Since the early 1990s, practical use of jeans has appeared consistently in products for interior use, various kinds of fashion-ware and fashion properties, as well as in fashion that is a conversion and interpretation of an outstanding fashion trend. And the search, providing that various symbols of jeans are sensualism, deviation, ostentation, amusement and multi-culture, shows that jeans represent the multifarious aspects of fashion culture. For the purpose and necessity of this search to meet different consumers' desires by the practical use of jeans and the development of fashion-ware. First, investigate the trend of jeans in 2005. Second, try to change the various uses of jeans by reflecting the trend of jeans. Finally, extend the range of choice by developing various goods. As a result, basic jeans have the strength of function, activity, and originality. Use of ornamental jeans can fully show their value as well as their emphasis of individuality in beauty. If we consider these points, we can minimize the limitations of jeans and make a practical use of the fashion trend, If we make the function of jeans stand out through the use of varieties of materials, the modem characteristic consumption will be met by the various change of use as well as by the clothes.
