콘크리트용 혼화재로 사용량이 날로 증대되고 있는 고로슬래그 미분말의 품질 차이가 콘크리트의 중성화에 어떠한 영향을 미치는지를 통계적으로 분석해 보았다. 현행 KS F 2563에 의하면 고로슬래그 미분말을 1종, 2종, 3종으로 구분하는데 3종에 해당하는 분말도 $4000cm^2/g$급 고로슬래그 미분말을 3곳으로부터 입수하여 Type A, B, C로 하여 다른 모든 조건은 동일하게 하고 혼입하였다. 본 연구에서는 기존의 그래프간의 단순비교를 통해 공학적 판단을 하는 오류를 배제하고자 평균값과 분산을 동시에 고려하는 통계적인 기법을 적용하였다. 분석기법에는 A, B, C 3개 집단간의 F검정과 각각의 쌍체비교를 위해 T검정 기법을 적용하여 통계적인 의미를 고찰해 보았다. 그 결과 유의수준 5%에서 중성화에 미치는 영향이 통계적으로 유의미한 것으로 나타났다.

In this paper, we verify the mediating effects of resilience on the relationship between smartphone addition and anger coping strategies, focusing on 299 high school students, and examine the effect of variables on students of general high schools and special purpose high schools. We found that smartphone addiction affects students' resilience and the resilience affects their anger-out and anger-in. It is also found that resilience has mediating effects on the relationship between students' smartphone addiction and anger coping strategies. As for students of general high schools, their smartphone addiction has positive effects on anger-out and anger-in while that of students of special purpose high schools affects their resilience, and the resilience affect their anger-out and anger-in. The results suggest that a high-level of smartphone addiction tends to reduce resilience, which lowers anger moderation, and stress the need of intervention by school type. Finally, this paper discusses implications based on its results and importance of further studies.

The purpose of this study was to examine how congruity between self-image and store image affects a customer's satisfaction with the retailer, loyalty towards that retailer, and patronage behavior toward that retailer in a fashion retailing context. In addition to the direct effects of selfcongruity on consumer responses, the mediating roles of satisfaction and retailer loyalty were also examined. A convenience sample of 137 college students participated in an online survey. Path analysis showed that self-congruity had a direct effect on satisfaction, but not on retailer loyalty and patronage behavior. However, the effect of self-congruity on retailer loyalty and patronage behavior was fully mediated by satisfaction. Satisfaction had a positive effect on both retailer loyalty and patronage behavior. The effect of satisfaction on patronage behavior was partially mediated by retailer loyalty. As supported in the study, self-congruity can induce retailer loyalty. Given that retailers have direct control over developing a certain store image that affects perceptions of self-congruity of their target market, the findings of the study provide useful information for fashion retailers. The findings of the study add to current selfcongruity literature by extending to fashion retailing and also by examining the mediating roles of satisfaction and retailer loyalty on the effects of self-congruity.

Adverse impact of Particulate Matters(PM10, PM2.5; PMs) significantly affects daily lives. Major countermeasures for reducing concentration of PMs were focused on emission source without considering spatial difference of PMs concentration. Thus, this study analyzed spatial·temporal distribution of PMs with observation data as well as potential contributing factors on PMs concentration. The annual average concentration of PMs have been decreased while the particulate matter warnings and alerts were significantly increased in 2018. The average concentration of PMs in spring and winter was higher than the other seasons. Also, the spatial distribution of PMs were also showed seasonality while concentration of PMs were higher in Seoul-metropolitan areas in all seasons. Climate variables, emission source, spatial structure and potential PM sinks were selected major factors which could affects on ambient concentrations of PMs. This paper suggest that countermeasures for mitigating PM concentration should consider characteristics of area. Climatic variables(temperature, pressure, wind speed etc.) affects concentrations of PMs. The effects of spatial structure of cities(terrain, ventilation corridor) and biological sinks(green infrastructure, urban forests) on concentration of PMs should be analyzed in further studies. Also, seasonality of PMs concentration should be considered for establishing effective countermeasures to reduce ambient PMs concentration.

Purpose : This research is descriptive research that investigated the effect of subjective health cognition and self-esteem of saeteomin on depression. Methods : Data had been collected with self-reported questionnaire and telephone interview for 85 people who are over 18 and lived in Gwangju and Jeonnam province from September 1st 2005 to November 30th 2005. Results : In the subjective health cognition of subjects, 33 people(38.8%) were bad and 55.3% was latent patients. To verify the controlling effect of self-efficacy and subjective health cognition on depression, the multiple regression, divided into two different stage, shows that the overall model was significant, where, in the first stage, adding subjective health cognition(F = 14.814, p = 0.000) and in the second stage, self-efficacy(F = 21.621, p = .000). The subjective health cognition affects depression about 14.1%, and self-efficacy affects depression about 18.8%. Both subjective health cognition and self-efficacy affects depression about 32.9%. Conclusion : These findings showed that the health status of Saeteomin was in poor Status. As a result the subjective health cognition and self-efficacy were significant factors to control the depression, those factors can be integral resources to develop effective social support and detailed strategy for Saeteomin.

This thesis is to analyze and investigate the influence of behaviors towards an organization of public officials due to the way their parents raised them. I tried to find out how their parents' raising way influences the individual characteristics, the human relationship, the job satisfaction, and the organizational commitment. It is proved that the personal characteristics of the organization members affect the human relationship in organization strongly. It is also proved that the way their parents raised them affects the personal characteristics. Therefore I can suggest that the way parents raised children affects the organizational behavior strongly. In addition to that, the personal characteristics of each public official highly affect the human relationship such as the relationship with seniors, colleagues, and subordinates in organization. I know that the way their parents raised them strongly affects the human relationships in organization. In order to find out the influence of organizational behavior of public officials due to the way their parents raised them, I used the Pearson's correlation analysis. I find that the public officials who lived with positive parents have high job satisfaction and organizational commitment, and have high self-esteem, self-control, responsibility, and have good relationship with their senior and colleagues administrative public official. Also, from this study we can find out the influence which parents' attitude has on children's satisfaction and devotion as adults. Therefore this study can suggest a new direction of public administration.

Purpose: This study is to investigate the effect of managerial ownership level in distribution and service companies on the stock price crash. The managerial ownership level affects the firm's information disclosure policy. If managers conceal or withholds business-related unfavorable factors over a long period, the firm's stock price is likely to plummet. In a similar vein, management's equity affects information opacity, and information asymmetry affects stock price collapse. Research design, data, and methodology: A regression analysis is conducted using the data on companies listed on the Korea Composite Stock Price Index (KOSPI) between 2012-2017 to examine the effect of the managerial ownership level on stock price crash risks. Results: Logistic and regression results indicate that the stock price crash risk was reduced as managerial ownership levels are increased. The managerial ownership level has a significant negative coefficient on stock price crash risk, negative conditional return skewness of firm-specific weekly return distribution, and asymmetric volatility between positive and negative price-to-earnings ratios. Conclusions: As the ownership and management align, the likeliness of withholding business-related information is reduced. This study's results imply that the stock price crash risk reduces as the managerial ownership level increases because shareholder and manager interests coincide, thereby reducing information asymmetry.
