The jadeite powder has a disadvantage affecting the stability of the formulation due to the agglomeration of the powder when applied to cosmetic formulations. To overcome this problem, a new composite powder was prepared by modifying the surface of jadeite powder and applied to foundation pact and sun stick. In this study, a triethoxycaprylylsilane among various surface modifiers was selected as an optimum component, and applied to each formulation by making the jadeite powder composite. As a result, the foundation pact maintained the clarity of the product color, and the sun stick gave about 30% higher UV blocking effect in the UVB area compared with that of the blank. In the user sensory evaluation, the formulation containing the jadeite powder composite showed a high score for the overall indicator. The stability evaluation of the formulation was also confirmed that it was stable against discoloration, detachment and hardness. In conclusion, the jadeite powder composite is stable as an inorganic pigment which is applicable to cosmetics as a multifunctional material while maintaining the color clarity of the product and acting as a booster for sunscreen agents.

The purpose of this study is to analyze the influence of university students' dependence on smart-phone on career attitude maturity and the mediating effect of interpersonal problem in the analysis path. For this purpose, the study implemented a survey on students of universities in Seoul and Gyeonggi-do area and carry out a structural equation for empirical verification with a total of 218 copies. As a result, first, high level of daily life disturbance and virtual world orientation of university students, have a positive effect on interpersonal problems. Second, high level of daily life disturbance and virtual world orientation of university students, have a negative effect on career attitude maturity. Third, interpersonal problems of college students had a negative effect on career attitude maturity, and they were found to be fully mediated in relation to smart-phone dependence and career attitude maturity. Therefore, this study suggests that it can be used as a basic data for the development and application of various programs promoting the career attitude maturity of university students.

The purpose of this study was to examine music-color association response(MCAR) of people with visual impairment through music-emotion scale and music-color scale. The study was conducted on 60 participants(30 congenital/ 30 adventitious) who are using services of two welfare centers at S and B cities. For this, four basic emotions (happiness, sadness, anger, and fear) mediated by music were selected, and MCAR to emotion-inducing music were analyzed through self-report method. As a result, first, there were found contrasts in MCAR between happiness and sadness according to type of emotion, however, similar in anger and fear. Second, in MCAR among three variables of the music-emotion scale(valence, arousal and intensity), valence was congruent with MCAR according to type of emotion, arousal marked high scores in negative emotions, and scores of intensity in happiness and sadness were higher than those in anger and fear. Third, there were no significant differences between two groups of people with congenital and adventitious visual impairments. It is meaningful that this study showed the MCAR can be mediated by music through investigating those of people with visual impairment.

This study purpose to empirically investigated the effects of Learning Presence perceived by university students at general universities who took Remote Classification in the first semester of 2020 on Learning Outcomes and the mediating effects of Learning Immersion. A total of 293 students were surveyed by conducting an online survey for about a month from Sep. 15, 2020, targeting college students attending general universities in Seoul and Gyeonggi-do. The results of the study are as follows: First, Learning Presence had an effect on Learning Immersion and Learning Outcomes, and Learning Immersion had an effect on Learning Outcomes. Second, Learning Immersion had a mediating effect on the relationship between Learning Presence and Learning Outcomes. This study is meaningful in that it verified the relationship between Learning Presence, Learning Outcomes, and Learning Immersion perceived by college students who took Remote Classification in COVID19 response dimension.

The purpose of this study is to explore the characteristics of spatial expression in the works of Terunobu Fujimori, Japan's leading eco-friendly architect, in line with the contemporary background on environmental issues. As a method of research, we will select five representative multi-room spaces from the 1990s to the present and explore the characteristics of expression in the space through literature research. As a result of the analysis, we were actively using the strategy of using natural materials to finish the space and introduce plants into the building. Japan's strategy of borrowing traditional methods was to use them as a way of expressing space, a way of expressing fantasy and deviance. We expect that the demands of modern people seeking novelty in this era and the eco-friendly building plan of feasible alternatives can be presented as another methodology for spatial design.

The study attempted to examine the structural model of the effects of health status and retirement aging anxiety on middle-aged workers. The subjects were collected from 263 40-59 year old middle-aged workers who work at three institutions in C and G cities. Results First, the variables affecting aging anxiety were aging preparation and health status, and these variables accounted for 52% of aging anxiety. Second, health status had a significant effect on retirement preparedness, and there was a significant indirect effect on aging anxiety through retirement preparedness. There was a partial control effect due to the difference in the path coefficient between health status and aging anxiety in the multi-group moderating effect of 40~49 and 50~59 years. Therefore, in order to reduce aging anxiety, it is important to find ways to prepare for various retirement, and a systematic management system is necessary.
