친수성 처리된 다공성 지지체를 이용한 폴리아마이드 박막 역삼투 복합막 제조 및 특성 분석

손승희,제갈종건,Son, Seung Hee,Jegal, Jonggeon 한국막학회 2014 멤브레인 Vol.24 No.4

기존의 폴리아마이드 박막 역삼투 복합막(PA TFC RO Membrane)은 우수한 분리투과특성을 지니고 있으나 내염소성이 상대적으로 낮은 단점을 지니고 있다. 본 연구에서는 이를 해결하기 위하여 표면에 -OH나 -COOH 기가 도입된 다공성 지지체를 제조하고, 그 표면에 폴리아마이드 박막을 형성하여 역삼투 복합막을 제조하였다. 제조된 역삼투막의 구조 및 분리투과 특성은 여러 가지 기기분석 방법과 투과테스트 방법으로 분석하였다. 폴리아마이드 박막을 제조하기 위하여 아민계 단량체로는 메타-페닐렌 디아민(MPD)과 2,6-디아민 톨루엔(2,6-DAT)을 사용하였고, 디엑시드계 단량체로는 트리-메소일 클로라이드(TMC)를 사용하였다. 제조된 복합막의 투과도는 800 psi에서 약 $1.0m^3/m^2day$ 이상이었으며 이때 염배제율은 99.0% 이상이었다. 내염소성도 친수성기가 없는 폴리설폰 지지체를 사용한 복합막에 비하여 우수한 것으로 나타났다. It is very well known that the conventional polyamide (PA) thin film composite (TFC) reverse osmosis (RO) membranes have excellent permselective properties, but their chlorine tolerance is not good enough. In this study, to improve such chlorine tolerance, microporous membranes containing hydrophilic functional groups such as -COOH were used as a support to prepare PA TFC RO membranes, employing the conventional interfacial polymerization method. Meta-phenylene diamine (MPD) and 2,6-diamine toluene (2,6-DAT) were used as diamine monomers and tri-mesoyl chloride (TMC) as an acid monomer. The membranes prepared were characterized using various instrumental analytical methods and permeation test set-up. The flux obtained from the membranes prepared so was more than $1.0m^3/m^2day$ at 800 psi of operating pressure, while the salt rejection was over 99.0%. The chlorine tolerance of them was also found to be better than that of the membrane prepared by using conventional polysulfone support without hydrophilic functional groups.

직장 어린이집 보육교사의 업무불안과 역할수행 간의 관계 - 원장 및 동료교사의 사회적 지지의 중재효과

강주연(Joo Yeon Kang),손승희(Seung Hee Son) 한국생애학회 2023 생애학회지 Vol.13 No.2

본 연구에서는 직장어린이집 보육교사의 업무불안과 역할수행, 어린이집에서의 사회적 지지의 관계에 대해 알아보고 업무불안에 따른 역할수행과 사회적 지지의 중재효과를 알아보고자 하였다. 이를 위해 D시에 위치한 직장어린이집에 근무하고 있는 만 3~5세 유아반 담임교사 116명을 대상으로 하였다. 사용된 설문지는 보육교사의 업무불안을 측정하기 위하여 교사용 불안검사지(STAS)를 이혜리(2016)가 번안한 척도를 사용하였다. 보육교사의 사회적 지지를 측정하기 위하여 박지원(1985)이 개발하고 김윤지(2017)가 유치원 교사용으로 수정한 도구를 사용하였다. 또한 보육교사의 역할수행은 이희경과 김성수(2002)가 개발한 도구를 박복매(2011)가 수정ㆍ보완한 척도를 사용하였다. 이 연구의 자료 분석을 위해 SPSS 18.0 프로그램을 사용하여, 기술통계, 독립표본 t검증, ANOVA, Tukey의 사후검증, 상관분석, 위계적 회귀분석을 실시하였다. 주요 연구 결과를 요약하면 다음과 같다. 첫째, 보육교사의 업무불안과 역할수행은 보육교사의 연령과 경력에 따라 유의한 차이가 나타났으며 최종학력에는 차이는 나타나지 않았다. 둘째, 보육교사의 업무불안과 역할수행은 유의한 상관관계가 나타났다. 수업불안을 많이 경험하는 교사일수록 보육 및 기본생활지도나 교육 및 교수활동을 수행하는데 있어 어려움을 겪는다고 할 수 있다. 셋째, 보육교사의 업무불안과 역할수행의 관계에서 원장과 동료교사의 사회적 지지의 중재효과가 나타났다. 원장의 사회적 지지의 중재효과는 불안이 높은 교사가 보육 및 기본생활지도, 교육 및 교수활동을 수행할 때 효과적이었으며, 불안이 낮은 교사의 경우 상담 및 정서적 지원, 연구 및 반성적 실천, 관리적 역할을 수행할 때 효과적인 것으로 나타났다. 동료교사의 사회적 지지의 중재효과는 불안이 높은 교사가 보육 및 기본생활지도, 상담 및 정서적 지원, 관리적 역할을 수행할 때 효과적이었으며, 불안이 낮은 교사가 연구 및 반성적 실천 역할을 수행할 때 효과적인 것으로 나타났다. 결론적으로 보육교사의 업무불안과 역할수행에 어린이집에서의 사회적 지지의 중재효과가 있는 것으로 나타났다. 이를 토대로 보육교사의 역할수행력을 높이기 위해서는 업무불안을 높은 교사들에게는 동료교사의 사회적 지지, 업무불안이 낮은 교사들에게는 원장의 사회적 지지를 통하여 역할을 더 효과적으로 수행할 수 있도록 대상에 맞는 교사 프로그램의 개발 및 실시와 교사 연수 등이 이루어져야 할 것이다. 또한 보육교사에게 사회적 지지를 제공하는 원장과 동료교사도 스트레스나 소진이 올 수 있으므로 이를 해소하고 격려할 수 있는 프로그램 또한 함께 개발되어야 할 것이다. This study confirmed the relationship between work anxiety, role performance of teachers at a childcare centers and social support. In addition, role performance according to work anxiety and the mediated effect of social support were investigated. We selected 116 teachers who teach at a childcare center in Daejoen. Lee Hye-ri’s (2016) and Park Ji-won’s (1985) questionnaires were used and modified by Kim Yun-ji (2017), Lee Hee-kyung and Kim Seong-su (2002), and Park Bok-mae (2011). For statistical analysis, Pearson's correlation analysis and hierarchical regression analysis were used. The results showed a mediating effect of social support on work anxiety and role performance of the childcare teacher. Based on this study, to improve the role performance of childcare teachers, it is necessary to develop and implement suitable programs and teacher training. Teachers with high work anxiety should use the social support of co-worker teachers, whereas teachers with low work anxiety should use the social support of the director. In addition, directors and co-worker teachers who provide social support to childcare teachers can suffer from stress and burn -out. Therefore, teacher education programs should be developed to solve these problems and encourage teachers.

청 · 민국시기 合夥의 계약관습과 법

손승희(Son, Seung-Hee) 동양사학회 2019 東洋史學硏究 Vol.146 No.-

‘Co-partnership’(合夥) during the Ming and Qing dynasties refers to the way of management or capital organization of merchants. Despite the introduction of the Western corporation system in the late Qing period, co-partnership in Shanghai industrial enterprises still accounted for a large portion even in the 1930s. This article focuses on how the co-partnership of the Ming Dynasty changed in the Republic of China and how it appeared in contract documents. Through this, I reviewed the process and aspects which the private contract practices that existed as a social norm enter the national legal system according to the implementation of modern civil law. The legitimacy of a business in a co-partnership system was in the agreement between parties. By clearly describing the contents, contract documents secured considerable binding power among the parties to the contract. Therefore, the contracts are legal documents that confirm the rights and obligations between partners. In traditional Chinese society where a related national law was absent, private order was maintained by long-term private contract practices. Contracts included basic terms such as the name of the business, the place and type of business, the name of the shareholders, the total amount of capital and the number of shares. When the Republic of China adopted contracts, they also recorded the shareholders’ meeting, the audit committee, the distribution of profits and sharing of debt repayment, which was more normative and complete. It seems to be normative as if it were similar to the agreements of modern companies due to the influence of modern corporate law. The most controversial issue in the operation of a business partnership was the liability for debt repayment, in which it was customary to adhere to the principle of sharing according to the amount of investment. However, the Civil Code in 1911 stipulated joint sharing, and the Civil Code in 1929 promulgated an infinite solidarity responsibility, resulting in conflicts among merchants. The government originally intended to enact a modern corporate law and convert traditional companies into modern companies, but merchants preferred traditional companies. Therefore, in order to minimize these conflicts, the government respected the existing status of traditional companies that did not belong to the modern Enterprise Law(公司法), but instead tried to put it into the legal system in the Civil Law(民法). The government recognized the traditional ways and systems established through contractual practices between parties. However, since the rights of creditors were not sufficiently protected, the law stipulated that they should be responsible for the repayment of debts.

The purpose of this study investigate the differences in children`s reading abilities of environmental print according to children`s age and types of parental literacy interaction. The subjects comprised 111 illiterate children, 3 to 4 years of age, and their mothers. The Children`s Reading Abilities of Environmental Print Scale (CRAEPS), Parent`s Literacy Interaction Rating Scale (PLIRS) as developed by Son (2012) were used in this study. The collected data are analyzed by means of descriptive analysis, K-mean cluster analysis, Correlations, and two-way ANOVA. The results of this study are as follows: Illiterate Korean children, aged 3 to 4 years, can read environmental print which are familiar to them, and an ‘open interaction style`` plays an important role in developing the child`s reading ability of environmental print. Therefore, in order to develop child literacy, it is necessary to research, not only teaching methods for using environmental print in the home, child care centers, and in kindergarten, but also parent education programs regarding the importance of the mother`s literacy interaction style.

The purpose of this study was to explore the effects of fathers socio-demographic variables and fathers literacy beliefs on fathers literacy interaction. Participants were 204 fathers who have children in 3 to 5 years of age. Data were analyzed by descriptive statistics, correlation analysis and stepwise multiple regression analysis. The findings are summarized as follows: (1) Father’s education level was generally correlated with ‘father role efficiency’, ‘open interaction’, ‘picture-book reading interaction’ (2) Monthly income of the household was related ‘father role efficiency’, ‘positive feelings on reading books’. (3) ‘Literacy ability development from books’, ‘father role efficiency’, ‘positive feeling on reading books’ were correlated ‘open interaction’ and ‘picture book reading’. But, ‘literacy ability development from books’, ‘father role efficiency’, ‘positive feeling on reading books’ were negatively correlated ‘direct interaction’. (4) The most influential factor on fathers ‘open interaction’, ‘direct interaction’ was ‘literacy ability development from books’. The most influential factor on fathers ‘picture-book reading’ was ‘positive feeling on reading books’. These findings highlight that ‘literacy ability development from books’ and ‘positive feeling on reading books may play critical roles in fathers literacy interaction. So, it is very important that adequate training and support on father’s literacy beliefs for fathers high quality literacy interaction.
