For a further understanding of the Chinese consumer, this study investigated 1) the effects of aesthetic consciousness on make-up attitude, and 2) the differences in the effect of aesthetics consciousness on make-up attitude among age groups. An online survey was conducted on female consumers belonging to the post-80s and 90s generations, living in Xian China. SPSS 24.0 and Amos 18.0 was used for data analysis. Confirmatory factor analysis for the research variables were performed and three factors of aesthetic consciousness (social relations consideration, internal consideration, and external consideration), and four factors of make-up attitude (psychological pleasure, self-satisfaction, consciousness of others, and tool of transformation) were identified. The results from the model test were : 1) aesthetics consciousness was found to vary depending on make-up attitude. Social relations consideration had a positive effects on psychological pleasure, self-satisfaction, and tool of transformation. Internal consideration had a positive effect on self-satisfaction and tool of transformation, and a negative effect on psychological pleasure. External consideration had positive effects on all four factors of make-up attitude. 2) In the post-80s participants, social relations consideration and external consideration had positive effects on all four factors of make-up attitude. Internal consideration s had a negative effect on consciousness of others and a positive effect on tool of transformation. In the post-90s participants, social relations consideration had positive effects on psychological pleasure, self-satisfaction, and tool of transformation. Internal consideration had positive effects on psychological pleasure and self-satisfaction.

Recently, there has been a lot of discussion about the regional pricing of electricity and electricity self-sufficiency. In Korea, power generation facilities are highly ubiquitous and there is an imbalance between electricity production and consumption regions. So it is proposed to charge different price by region, instead of the current nationwide uniform price, and the regional electricity self-sufficiency rate is proposed as a criterion for identifying electricity production and consumption regions. However, many discussions set the spatial unit for measuring electricity self-sufficiency by 17 Si·Do, which needs to be analyzed for its appropriateness. In this study, we analyzed the electricity self-sufficiency rate using 17 provinces and 229 Si·Gun·Gu as the spatial unit. As a result of the analysis, there are 7 and 10 electricity producing and consuming regions at Si·Do level, but 38 and 191 at Si·Gun·Gu level. In addition, although the electricity self-sufficiency rate measurement has the advantage of identifying electricity production and consumption areas in a simple and intuitive way, we points out that it has some problems with the criteria for regional pricing of electricity.

Renewable and unutilized energy (biogas power generation, wind power, solar, small hydro-power, sewage heat source, etc.) seems to be suitable to install for the sewage treatment facilities. There are 357 sewage treatment plants in 2007. 17 plants among these have been operating for self-supporting energy by using solar power, small hydro-power and biogas in 2008. Newly built sewage treatment plant of 96,000 $m^3$/day for a newtown is expected to get up to energy consumption of 10 GWh/yr. If solar energy, small hydro-power and biogas-equipments were applied to the new treatment plant, self-supporting energy of the new sewage treatment plant will get up to 56.1%. As a results, about 2,379ton $CO_2$/yr $CO_2$ emission reduction can be expected by using renewable energy. These efforts for self-supporting energy will lead sewage treatment plant to new energy recycle center.

nZEH (net-Zero Energy House) is defined as a self-sufficient energy building where the sum of energy output generated from new & renewable energy system and annual energy consumption is zero. The electricity generated by new & renewable energy system with the form of distributed generation is preferentially supplied to electrical demand, and surplus electricity is transmitted back to grid. Due to the recent expansion of houses with photovoltaic system and the nZEH mandatory by 2025, the rapid increase of distributed generation is expected. Which means, we must prepare for an electricity-power accident and stable electricity supply. Also electricity charges have to be reduce and the grid-connected should be operated efficiently. The introduction of ESS is suggested as a solution, so the analysis of the load matching and grid interaction is required to optimize ESS design. This study analyzed the load matching and grid interaction by expected consumption behavior using actual data measured in one-minute intervals. The experiment was conducted in three nZEH with photovoltaic system, called all-electric houses. LCF (Load Cover Factor), SCF (Supply Cover Factor) and $f_{grid}$ (Grid Interaction Index) were evaluated as an analysis indicator. As a result, LCF, SCF and $f_{grid}$ of A house were 0.25, 0.23 and 0.27 respectively; That of B house were 0.23, 0.23, 0.19, and that of C were 0.20, 0.19, 0.27 respectively.

With the development of related industries, there is a growing demand for the training of beauty professionals. At a time when there is a growing social interest in Cosmetology, there is a need to review functional Beauty Education. Generation Z, born after 1995, has the characteristics of a 'Digital Native' and is expected to be the main driver of future consumption. This study is intended to propose the orientation of Beauty Education of University considering the characteristics of the digital generation, Generation Z, in an era of declining school-age population. The results from the preceding and literary studies are as follows: First, Generation Z regards cosmetology as fun tool for self-realization. Second, Beauty Education of University should be designed as a creative curriculum combined with psychology, philosophy, aesthetics, etc., as well as acquiring professional skills. Third, it is believed that the learner-centered Beauty Education method using mobile video contents will be effective. Since the discussion of Beauty Education considering the characteristics of Generation Z is still in its early stages, further research on the direction of Education needs to be made in the future.

The purpose of this study is to critically interpret generational trends in contemporary Korea through understanding the consumer experiences of luxury bag purchases of women in their late 20s and early 30s. Previous studies on luxury consumption tend to focus on an analysis of the value of luxury products as a sign and a symbol, the characteristics or class identity of luxury consumers, or expressive behavior in terms of ideal self-image. While including these factors, this study also expands the scope to a reflexive understanding of the social structural context behind the phenomenon of personal consumption. This was achieved by considering consumption in terms of the style and practice of everyday life, as well as its opportunities and limitations. In particular, we pay attention to how luxury bags are reproduced as media, which is a process that is circulated back to consumption, and through this process, this study reflects on capitalist life and subjects.

Recent concerns about environmental conditions have triggered the growing interest in using green energy resources. These sources of energy, however, bring new challenges mainly due to their uncertainty and intermittency. In order to alleviate the concerns on the penetration of intermittent energy resources, this paper investigates impacts of realizing demand-side potentials. Among different demand-side management programs, this paper considers demand response wherein consumers change their consumption pattern in response to changing prices. The research studies demand response potentials from different load sectors on generation system well-being. Consumers' sensitivity to time-varying prices is captured via self and cross elasticity coefficients. In the calculation of well-being indices, sequential Monte Carlo simulation approach is accompanied with fuzzy logic. Finally, IEEE-RTS is used as the test bed to conduct several simulations and the associated results are thoroughly discussed.

This study sought to investigate the relationship between perception, body awareness, and beauty management behavior in the untact era in their MZ generation's, and as a result of the study, it was confirmed that there is a causal relationship between variables. For the empirical analysis of the study, a survey was conducted online(Google questionnaire) in Seoul/Gyeonggi area from June 7 to 26, 2021. Of the 548 questionnaires, 512, excluding 36, were analyzed using SPSS V.21.0. Among the sub-factors of perception in the untact era, it was confirmed that the social environment perception and human relationship perception are key factors that negatively affect body consciousness and beauty management behavior, and so does self-awareness(p<.05). Next, it was confirmed that, among the sub-factors of body consciousness, appearance management awareness and appearance/body care effort were key factors that positively affected beauty management behavior, and that appearance confidence was also an important factor that positively affected beauty management behavior(p<.05). Therefore, through this study, we intend to provide basic data for product development, programs, and marketing strategies that can cope with changes in the beauty consumption market in preparation for the post-COVID era.

The idea of identification have become a subject of discussion ever since the time man started to contemplate on the meaning and value of his being. However, the concept of identity defined by theorists such as sociologists or cultural historians influence the consumption pattern of the major consumer group, in conjunction with the advent of the mass consuming age. The conflict and mutual realization among variable generations and residential areas of different. consumer levels profoundly affect the formation of the identity of the new generation and the role and experience of women. This series of transit is progressing more rapidly due to the characteristic situation of the expiration of a millenium. Advertising strives to control our interests and ideas on the products we choose to use and affects our identity by manipulating images of successful people. People tend to be influenced more significantly by the mass-culture than by people around them, such as family or friends, in rendering their self?identity; in which process, adopting the identity produced by mass-media and advertising. Such identity is conducted partly of the product identity and the stereotyped image suggested by mass-media. This study bears significance in the attempt to provide actual data and expand the realm of ideas and planning in future advertising through demonstrative analysis of self-identity creative in Korean TV advertising.
