The purpose of this study was to investigate removal efficiencies of contaminants in night soil treatment plant using the B3 system. The samples were collected from retaining tank and settlement tank in Yechon night soil plant. We experimented concentrations of BOD, COD, SS, TN and TP. Concentration data were processed using removal efficiencies by season and correlation analysis with pilot running parameters. Removal efficiencies of total organic carbon was over 96% , TN was 98% during summer, 80.9% during winter. In the case of TP, the highest removal efficiencies was 94.1% during fall and the lowest removal efficiencies was 82% during spring. Results of correlation analysis showed two positive correlation groups and one negative group. Positive correlations were among temperature, BOD and TN. The others were pH, BOD, COD, SS, TN and TP. Negative correlation were among MLSS, BOD, COD, SS, TN, TP.

초등학교 학교폭력 책임교사가 경험하는 스트레스에 대한 개념도 연구
김은석(Kim Eun Seok),서윤하(Seo Yun ha),이지연(Lee Jee Yon) 고려대학교 교육문제연구소 2018 敎育問題硏究 Vol.31 No.2
본 연구는 초등학교 학교폭력 책임교사들이 학교폭력 사안처리와 관련하여 어떠한 스트레스를 경험하고 있는지를 살핌으로써 이들을 전문적으로 조력하기 위한 방안을 모색하는 것을 목적으로 실시되었다. 이를 위해 학교폭력 책임교사 11명을 대상으로 초등학교 학교폭력 책임교사가 경험하는 스트레스에는 어떠한 것이 있나요? 라는 초점 질문을 사용하여 인터뷰를 실시하여 이들의 스트레스의 개념적 구조를 확인하였다. 인터뷰 자료를 바탕으로 최종적으로 64개의 핵심 진술문이 생성되었으며, 연구 참여자들의 분류 및 평정 작업을 거친 자료로 다차원 척도법과 위계적 군집분석을 실시하였다. 연구 결과, 초등학교 학교폭력 책임교사들이 경험하는 스트레스는 관계-시스템 및 부정적 정서-정체감 혼란 의 두 가지 차원으로 구성된 개념도 상에 위치하는 것으로 나타났으며, 이들이 주요하게 경험하는 스트레스로 (1) 업무 처리에 불만과 심리적 부담감을 느낌, (2) 학부모간 분쟁 조정에 어려움을 느낌, (3) 학부모의 감정적 협박과 경계 침범으로 힘듦, (4) 처리 절차가 학생에게 교육적인지 회의감이 느껴짐, (5) 전문적 협력 체계의 부재로 인한 곤란을 느낌, (6) 부과된 역할이 모호하고 광범위하여 압도됨의 여섯 가지 군집이 도출되었다. 이러한 연구 결과가 의의하는 바와 제한점, 그리고 후속 연구를 위한 제언을 논의하였다. The present study aims to clarify the conceptual structure of the stress experienced by teachers in charge of school violence at an elementary school and to search for ways to support them. For this purpose, the focus interview question was What are your stress experiences as a teacher in charge of school violence . Based on the interview materials, we extracted 64 core statements and conducted multidimensional scaling and hierarchical cluster analysis after grouping and evaluating statements by participants. The results showed teachers experience stress along with two dimensions, Relationship-System and Psychological Problem-Professional Problem . Their major stress were (1) Experiencing complaints and psychological burden, (2) Having difficulties in controling troubles between parents, (3) Suffering from emotional threat and boundary violation by parents, (4) Feeling skepticism whether the procedure is educational, (5) Having difficulties in seeking professional assistance, (6) Being overwhelmed by role overload and role uncertainty. Finally, implications. limitations, and suggestions for future research were discussed.

한국 Z세대의 관계적 자기, 자기합리화, SNS 인증샷 행위가 상징적 소비성향에 미치는 영향요인: Moschis와 Churchill의 소비자사회화 이론을 기반으로

Purpose: This study was aimed to identify the influencing factors of relational self, self-rationalization, and SNS photo-sharing activities on the symbolic consumption disposition of Generation Z in Korea. Methods: The subjects of this study were 191 college students from 8 provinces in Korea. Data were collected using scales for relational self, self-rationalization, SNS photo-sharing activities, and symbolic consumption disposition. Statistical analysis was conducted using a stepwise multiple linear regression model in SPSS 25. Results: The most influential factors of self-oriented symbolic consumption disposition were product attributes as a type of self-rationalization (ß=.35, p<.001), receiving support as a type of relational self (ß=.27, p<.001), and satisfaction with SNS photo-sharing activities (ß=.25, p<.001) accounting for 34% of the variance. Meanwhile, emotional consolation as a facet of self-rationalization (ß=.31, p<.001), the social capital aspect of SNS photo-sharing activities (ß=.27, p<.001), and the instrumental aspect of relational self (ß=.24, p<.001) were the most influential factors of other-oriented consumption disposition, explaining 38% of the variance. Conclusion: Findings of this study indicate that self-rationalization is the most influential factor on consumption disposition of Generation Z. As self-rationalization is an immature defensive mechanism, there is a need to develop new educational content to promote more rational consumption behavior among this generation.
