정순화(Soon Hwa Chung),정옥분(Ock Boon Chung) 한국아동학회 1994 兒童學會誌 Vol.15 No.1
The primary purpose of this study was to investigate the validity of a component model of gender role and differences in children`s gender concepts with age and sex. The secondary purpose was to investigate the relationship between children`s gender schema and memory as well as preference for gender related task. 181 children were interviewed about gender concepts and gender related tasks. Results indicated that three dimensions of the component model (i. e., gender label-component links, within-component links, between-component links) were significantly related to each other. The mean scores of gender role knowledge and attitude were different with age but not with sex. The results of the regression analysis showed that children`s age, sex, and gender role attitude explained both memory and preference for gender related tasks. The component model had better explanatory power than the simple model. The findings of the present study suggest that children`s gender concepts are better described in terms of the component model than the simple model and may contribute to a theoretical rationale for gender schema theory.

정순화(Soon Hwa Chung) 한국아동학회 1992 兒童學會誌 Vol.13 No.2
The purpose of this study was to investigate children`s conceptions about gender and the relation between gender conceptions and preference for gender related tasks. 130 children were interviewed about gender and gender related tasks. Data were analyzed with the component model of gender schema. Results indicated that children`s gender schema in the attitudes domain was significantly different with age in all components but not different with sex. The gender schema in the knowledge domain was significantly different with age in within component and between component links, and with sex in the gender label-component and within component links. The difference between the gender inhibitory score and gender facilitative score was significantly different with age, sex, and children`s gender schema. The findings that gender schema influenced the children`s preferences for gender related tasks suggests a theoretical rationale of gender schema theory.

The purpose of this study was to understand children`s viewpoints on their fathers from a phenomenological perspective. Sixty nine elementary school children (2nd and 5th grade) were asked to write poems about their fathers. Through the poems, they described their feelings towards their fathers in their own words. Results indicated that the most prominent and popular description for the father was in terms of the provider of the family. Because of the excessive emphasis on the provider role, fathers are very busy and tired, and can not Participate actively in their children`s daily life. As a result, many fathers are in an on-looker position in their homes, and their children are spoiled. On the other hand, children described their fathers as warm, kind- hearted, respectable and great images that gave everything to their children. They liked and sincerely appreciated these aspects of their fathers. Because of the gap between the ideal image of the father and the actual provider image of the father, children experience conflict and a psychological deficit of a father. We believe that this problem will be improved through the fathers` own awareness of their role which pays more attention to our children`s wellbeing and a reform of the existing social system.

정서발달의 관점에서 본 우리나라의 전통태교 : 태교신기를 중심으로
정순화 ( Soon Hwa Chung ) 대한가정학회 2014 Human Ecology Research(HER) Vol.52 No.1
The purpose of this study was to analyse the principles and methods of Taegyo-Singi with regard to emotion and to review basic informations on Taegyo programs for promoting prenatal development. Taegyo-Singi was analyzed as follows. First, the contents of Taegyo-Singi were classified into principles and methods of Taegyo . Second, the domains of emotion were categorized into emotional perception, emotional expression, emotional understanding, and emotional regulation based on the classification of Mayer and Salovey, and Moon. Third, the contents of Taegyo-Singi were classified into the four domains of emotion. Finally, the reliability and validity of the classification were obtained through inter-rater agreement and analysis of content validity. The results indicated that first, the principles of Taegyo presuppose parental influence on temperament formation, and that the emotional states of the mother in the prenatal and prepregnancy period is the most influential variable in a child``s temperament formation. Second, the methods of Taegyo presuppose that the human mind interacts with their behavior. Therefore, through emotional support of family members, ``jon-sim (the serene mind)`` and ``chung-sim (the mind from rectitude)`` are the key methods of Taegyo . This means that the Korean tradition of Taegyo focused on the emotional domain of development, especially emotional regulation. This coincides with the emotion-focused temperament theory that individual differences in temperament reflect individual differences in emotion.

신규 합성 당지질 함유 리포솜의 In Vitro 안정성
송충길,정순화,성하수,조선행,신병철,Song, Chung-Kil,Jung, Soon-Hwa,Seong, Ha-Soo,Cho, Sun-Hang,Shin, Byung-Cheol 대한화학회 2007 대한화학회지 Vol.51 No.1
리포솜은 수십~수백 나노미터 크기의 소포체(small vesicle)로서 약물전달에 유용한 구조체이나 체내 혈류 순환계(blood circulatory system)에서 구조적 불안정성에 의해 체내 순환시간이 짧고 세망내피계(reticuloendothelial system)에 의해 소실되어 이를 개선하기 위한 다양한 연구가 시도되고 있다. 본 연구에서는 이당류(disaccharide)로서 락토오스와 슈크로스가 1,2-디스테아로일-sn-글리세로-3-포스포에탄올아민(1,2-Distearoylsn-glycero-3-phosphoethanolamine, DSPE)과 공유결합된 새로운 당-DSPE 유도체를 합성하고 이를 리포솜의 구성성분으로 하는 리포솜을 제조함으로써 리포솜의 표면이 이당으로 수식된 리포솜을 제조하였다. 제조된 리포솜의 입자크기는 대략 100 nm였으며, 표면전하 값은 당이 수식되지 않은 대조군 리포솜이 -10 mV를 나타내었으나 당-DSPE 유도체를 함유한 리포솜의 경우 리포솜 표면에 존재하는 당의 수산화기에 의하여 표면전하의 값은 -25 mV를 나타내었다. 리포솜 내부에 모델약물인 독소루비신(doxorubicin)의 로딩효율은 약 90%를 나타내었다. 당-DSPE 유도체 함유 리포솜의 in vitro 안정성은 혈청 내에서 단백흡착량의 변화 및 리포솜의 입자크기를 관찰하여 평가하였다. 당-인지질 유도체를 함유한 리포솜은 당-인지질 유도체를 함유하지 않은 리포솜 또는 폴리에틸렌글리콜(PEG) 수식 리포솜에 비해 단백흡착의 양과 혈청 내 입자크기의 변화가 적은 것으로 관찰되었다. 이당이 결합된 DSPE와 이를 함유한 리포솜은 혈액내 안정성이 향상되어 체순환계 내에서 장시간 순환이 가능한 약물전달체로서 유용할 것이라 사료된다. Liposomes having particle size from several tens to hundreds nanometers are efficient carriers for injectable drug delivery. Enhancement of liposome stability in bloodstream has been studied because of its relatively short circulation time and fast clearance from human body by reticuloendothelial system (RES) in blood vessel. In this study, new disaccharide-1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) derivatives in which lactose or sucrose as the disaccharide molecule was conjugated covalently to DSPE were synthesized. Liposomes of which surface had disaccharide molecules were prepared by incorporating the disaccharide-DSPE into liposomes as one of their lipid components. Particle size of the prepared liposomes was approximately 100 nm. The liposomes of which surface were modified with the disaccharide-DSPE showed -25 mV of zeta potential value due to the presence of hydroxyl groups on their surface, while the unmodified control liposomes showed -10 mV of zeta potential value. Loading efficiency of model drug, doxorubicin, into liposomes was about 90%. Stability of the disaccharide-modified liposomes in vitro was evaluated by monitoring the amount of protein adsorption and particle size of the liposomes in serum. Disaccharide-modified liposomes were more stable in serum than unmodified control liposomes or polyethyleneglycol (PEG)-modified liposomes due to less adsorption of serum protein and hence less increase of their particle size. The liposomes of which surface was modified with disaccharide-DSPE conjugate can be used as long-circulating carriers for drugs having high toxicity or short half-life time due to their enhanced stability in blood circulatory system.

Researchers examined elementary school children`s experiences and the way that their mothers scolded them. In their writings, the children reported that their mothers under-estimated them, and assumed that they were not able to do anything by themselves. This reflected on the way that the mothers disciplined their children. The mothers were not a good model of proper behavior and did not treat the siblings fairly. The mothers were directive and valued results over effort. The children confessed that they felt suicidal, miserable and wanted to run away from home. They had a love-hate relationship with their mothers. They had to hide their real feelings and show love and respect towards their mothers. They had conflicts in dealing with these feelings. Their inability to show their real feelings and their dependency on their mothers made them return home, much like a boomerang. As a result, the children learned how to respond quickly in avoiding scolding situations. Furthermore, they learned the most important lesson; that it is all right to be abusive as long as it is for their or anybody else`s own good.
