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.

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 was to examine the effect of dance activities on the emotional quotients of children in early childhood. It`s attempted to identify the relationship of their participation in dance activities to their four emotional quotient areas, including self-awareness/expressiveness, ability to control oneself, ability to perceive others, and ability to control others/interpersonal skills. The subjects in this study were girl preschoolers at the age of 5 to 7, who attended a dance academy in the city of Daegu. The findings of the study were as follows : 1. The young children who took part in dance activities for 13 or more months were better at self-awareness/expressiveness, ability to perceive others, and ability to control others/interpersonal skills. 2. The seven-year-old preschoolers excelled the others in self-awareness/expressiveness and ability to control others/interpersonal skills. 3. Those who were actively involved in dance activities outperformed the others in every area including self-awareness/expressiveness. 4. The preschoolers who attended both dance and piano academies or who attended both dance institute and kindergarten outdid the others in self awareness/expressiveness and ability to control others/interpersonal skills. 5. The extent of participating in dance activities had the biggest impact on their emotional quotient in every area, followed by the term of participation, type of academy, age and frequency.

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 is to develop a scale for evaluation of Parent`s Literacy Interaction Rating Scale (PLIRS) for preschool children and to examine its validity and reliability. The participants of this study were 342 Korean mothers with children of 3 to 5 year olds. The methods for data analysis included item analysis, factor analysis for construct validity, Pearson correlations between PLIRS and two sub tests of EC-HOME for concurrent validity, and Cronbach`s α for reliability. The item discrimination was determined by comparing the highest and lowest groups using Chi-square (χ2), and Cramer`s V. The 25 items of the scale were found to be satisfactory in item discrimination. The concurrent validity was also identified by correlation between PLIRS and two sub tests of EC-HOME. Factor analysis revealed that the structure of the PLIRS consisted of three factors: ``open interaction``, ``directive interaction``, and ``picture-book reading interaction``. ``Open interaction`` is based on ``Whole Language Approach``, such as ``I have my child write as he/she likes even if they spell wrongly.`` ``Directive interaction`` is based on ``Code Emphasis Approach``, such as ``I have my child take dictation.`` ``Picture-book reading interaction`` is how parents read picturebook with her/his children, such as ``When I read a picture book to my child, I ask various questions about a book story.`` The Cronbach`s α for internal consistency reliability range was .78 to .87 for three subscales. It was concluded that PLIRS was valid and reliable to examine the literacy interaction between parents and children in home.
