In this study, a model is developed based on Life Cycle Energy Analysis (LCEA) method with Genetic Algorithm (GA) to determine optimal diameter of Water Distribution System (WDS). For hydraulic analysis the EPANET2.0 program is linked with developed model, pipe-aging equation and pipe-breakage equation are built in to developed model to simulate pipe change through life cycle. The model is then applied to two sample WDSs for optimal energy design. After determining optimal diameter for each WDS, the total cost is calculated based on determined diameter and compared with well-known optimal diameter set of each WDS. Results show that optimal energy design of WDSs through the developed model can be an alternative option for optimal design of WDSs for reducing energy with lower in cost.

The aim of this study is to shed light on essentials of Suprematist artists focusing on Malevich and their works in relation to modem design, and to examine their roles in the modem design industry compared to those of modem designers. The study obtains the following result on Suprematist artists and their works in Russian avant-garde in terms of modem design. Firstly, Suprematist artists had a great deal of interest in practical design although it seemed Suprematist were replaced by utilitarianism in avant-garde during the Russian revolution. Secondly, Suprematist artists were the first artists to bring the birth of modem design trends by applying their art in geometric forms to clothing and fabric design as well as ornaments and handicraft. Thirdly, the artists' attempt to work with needle workers made it possible to set achievements in design and modem decorative art exhibitions in various fields of art-life. As for the role of modem designers, Suprematist artists including Malevich have significant meanings as follows: Firstly, Malevich was a creative, future-oriented artistic designer who realized zaum of painting on the stage and created suprematistic mode in a cosmic point of view in order to agree with the environment. Secondly, Suprematist artists knew the importance of works that were produced by craftsmen and worked together with them. Therefore, the designers could maintain fabric decoration in difficult conditions knowing the importance of the high value-added industry. Thirdly, they were artists in real life who embodied the ideas and theories of Suprematist in sample works by recognizing the need of changes in life environment: they planned to set a new visual world in art but did not confine the idea only to painting.

PURPOSES : This study proposes standards for rural access road pavement section and thickness design considering existing access road construction conditions; the study also proposes a complementary policy that can be used for design convenience. METHODS : Various literature review and case studies had been performed in terms of rural access road section and thickness design, both domestically and internationally, and this was followed by domestic rural access road field surveys. KPRP and KENLAYER were used to analyze the commonalities and predict the remaining life. Data on real cost is used to select an appropriate construction method through economic analysis. RESULTS : The economic efficiency of concrete pavement ($15{\times}15$) was the highest in terms of economic efficiency of performance life and traffic volume. In the case of asphalt pavement, it is considered that the most economical method is to implement micro-surfacing method four times as a preventive maintenance method (once every 10 years and 4.5 years for asphalt concrete pavement and MS construction method, respectively). Repairable asphalt pavement is advantageous for areas where heavy vehicles are expected to pass. In the case of other general areas, it is considered economical to place concrete ($15{\times}15$) pavement. However, as analytical results on its performance life are unavailable, it is to be considered for study in the future. CONCLUSIONS : This study proposed interim design guidelines based on various domestic and international design guidelines and case studies. However, in order to develop the final design criteria applicable to the field, it is necessary to (a) estimate the bearing capacity of the lower level of the pavement at various sites, (b) estimate the daily traffic volume, (c) implement advanced low-cost pavement technologies, and (d) propose maintenance standards and techniques for long-term performance.

Make-up culture has recently emerged as a major trend among adolescents, and their knowledge of this culture is acquired from their peers. Adolescence is a period in which peer relationships have a significant effect on individuals' behavior and self-esteem. Also, adolescents are conscious of others' evaluation because they only want to exhibit their ideal-self. They generally apply make-up for various reasons; pursuing ideal beauty, concealing their insecurities and improving their own self-esteem. The purpose of this study is to design and implement the MUSE(Make-Up & Self-Esteem) project, to reduce self-esteem disparity based on make-up status. Ten female adolescents(mean age=17.0 yrs, SD=1.49) participated in the MUSE project, in which the participants gradually reduced their make-up steps and posted feelings about this on SNS. Also, events were designed for the participants to enhance their interest and become more focused on themselves without make-up. Resultantly, it was obeserved that after the project, the gap between the particiapnts' self-esteem with and without make-up decreased. More specifically, there was no significant difference in self-esteem with make-up before and after participating in the project, but a significant increase was observed in self-esteem without make-up after the project. Although the participants were mostly satisfied with the project, individual interviews were conducted to obtain feedback regarding how the project could be improved. The participants suggested that future project could be developed within their own peer group and the term of the project could be extended so that the participants could become accustomed to daily make-up reducing steps.

The major goal of this study is drawing design plan factors considering residents' life cycle and life style when remodeling design is needed. By drawing such design factors, the study will propose an alternative remodeling design plan. Such design method was defined as Multi-Dimensional module design method. And constructing data-system based on Multi-Dimensional module was secondary goal in this study. The details are as follows: Based on analysis of Residents' demand for remodeling and features of emotion-design applied to remodeling, the system which is suitable for application in remodeling design method was conducted. Based on the type of construction materials, the level value was set up according to emotion-factor application. Also, by conducting coding operation according to the distinction of construction materials, this study seeks the unit drawing method of information for constructing emotion-information system.

The plan that supports the healthy lives of the aged continuously is required as their population increases constantly. The 'healing environment' for the aged has been emphasized in the geriatric hospitals and convalescent hospitals mainly so far, but most of them are experiencing the unstable status such as fatigue and pain at the level that they can barely manage to carry out daily life. So, the plan of applying design pattern of biophilic in lobby of senior welfare center was willing to be sought in this paper to support the psychological stability and constant health within the range of daily life and activities for the aged. In this research, design pattern elements of biophilic and applying characteristics for each indoor space in lobby of senior welfare center were analyzed through the advanced research, theory consideration and case studies in Korea and foreign countries, and total 22 design pattern elements of biophilic and 52 design elements were drawn. It is expected that it can be used as the guideline and design guide for applying design pattern of biophilic hereafter.

Purpose: This study investigated the effect of depression, life stress and resilience on quality of life among middle-aged women. Methods: A descriptive correlation study design was used with a convenience sample consisting of 201 middle-aged women recruited from an urban area. SPSS 21.0 was used for a descriptive analysis, t-test, ANOVA, Pearson's correlations and multiple-regression analysis. Results: Quality of life had a significant positive correlation with resilience(r=.53, p<.001) and negative correlation with life stress(r=-.27, p<.001). The significant factors for quality of life were resilience (B=.425, p<.001) marital-status (B=.227, p=.001) and health status (B=-216, p=.001). These factors explained 36.8% of the variance in quality of life. Conclusions: In conclusion, to promote quality of life middle-aged women, there is a need to develop an intervention program to improve resilience.
