The study was designed to examine what type of daily stress factors kindergarten children have and what kind of coping behaviors they apply. A total of two hundred and fifty children was employed for the data to be surveyed and analyzed. The results of the study are summarized as follows. First, kindergarten children were experiencing the following daily stress factors: Difficulty with the family and parents was the most severely stressful factors, and difficulty with the peers, difficulty with the self-esteem, and difficulty with the academic work were shown in decending order, in terems of the severity of the stress. Second, the most severely stressful the kindergartner experiencing were the parents' favoritism toward a particular sibling the family and difficulty with getting along with their peers. Third, in terms of stress factors, the coping behaviors the kindergartner used tended to be emotional and defensive. Especially with relatevely severely stressful factors, they tended to be more defensive. However, with relatively lower level of stressful factors, the children, applied problem-centered copying behaviors. Fourth, in the evaluation of the stress factor and copying behaviors, higher levels of reliability and validity were shown. One of the speculations about the reasons might be study included the person to person interview method in the process of data collection.

황현정,전혜정,최근원,김영채 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

치커리와 쑥갓에 있어 식물조직배양이나 형질전환 과정에 필요한 무균 절편체를 얻기 위한 적절한 방법을 제안하기 위해 기내 파종을 위한 소독조건과 배지조성 및 종류에 관한 실험들이 실시되었다. 치커리 'Precole'은 10% NaOCl, 15분간, 'Chiavari'는 5% NaOCl, 15분간이 기내파종 시 발아 및 자엽전개를 촉진시키고 오염발생을 억제하는 조건으로 선발되었다. 쑥갓에서는 발아 및 자엽전개율에 있어 NaOCl 처리 간에 차이는 없었지만 10% NaOCl, 30분간 처리에서 가장 낮은 오염율이 관측되었다. 치커리와 쑥갓의 발아와 자엽전개율 모두 인조토양배지의 사용으로 MS 배지에 비해 현저히 향상 되었다. 비록 육안으로는 오염여부를 관측할 수는 없었지만 이들 인조토양배지에서 자란 쑥갓 묘의 자엽을 MS배지에 치상하여 배양 시에는 오염증상이 나타났으며 이들을 NaOCl 1%로 15분간 소독 후 치상한 결과 오염율을 현저히 낮출 수 있었다. Experiments on the sterilization condition and medium composition and type for in vitro sowing were conducted to suggest a proper way to produce enough aseptic explants for tissue culture or transformation study in chicory and garland chrysanthemum. Fifteen minutes soaking treatment with 10% NaOCl for chicory 'Precole' and 15 minutes with 5% NaOCl for chicory 'Chiavari' were selected as proper sterilization conditions to promote in vitro germination and cotyledon expansion and inhibit the seedling contamination from seed itself. In garland chrysanthemum, there was no significant difference in germination and cotyledon expansion ratio among NaOCl treatments, but the lowest seedling contamination ratio was observed by 30 minutes soaking with 10% NaOCl. Both germination and cotyledon expansion ratio in chicory and garland chrysanthemum were significantly increased by using the artificial soil media in contrast to MS media. Although seedling contamination with the artificial soil media could not be observed with bare eyes, cotyledon explants harvested from the plants grown on the media showed some fungal growth when they were placed onto MS media for further culture. However the percentage of the contamination from these explants was dramatically decreased by 15 minutes sterilization with 1% NaOCl.

The purpose of this study was to investigate longitudinal growth and development of young children and follow-up effects of the educare program in the PNU Day Care Center. Particularly, the first objective of this second report of study was the comparison the entire domains of development with age between the Oct. of 1995 and the Dec. of 1998. The second objective was to analyze the developmental .changes of 5 children who entered the center in 4 years old since Oct. 1995. The subjects of this study were 448 children(241 boys, 207 girls). The instruments of this study were the KISC and KEDl-WISC(for intelligence test), the Learning Readiness Test, the Social and Emotional Scale, Height Scale and Weight Scale( for physical growth). The tests were carried out 2 times per year (the early of the year and the late of the year). Results from comparsion across the 1st through 7th tests during 3 years indicated that the mean of the height was increased about 1-8cm for all of 2-5 years old children. The mean of the weight also was increased about 1.5-4.0kg except 2 years old children. The intelligence score (T score) by KISC was increased around 6-42 points except 6 years old boys and girls. In the intelligence score by KEDl, there was improvements of average 8 points for 7 years old children. In the learning Readiness Test of 5, 6 years old children, the scores all of children except 6 years old girls got were decreased. The scores of 6 years old girls were incresed 6 points in the Dec. of 1998. In the Social and Emotional Scale, there was big improvement of scores between in the 1st test and in the 7th test. These results were discussed in the view of sample size, developmental characteristics, test instruments and educare program of the PNU day care center.

어머니가 지각한 영아기질과 어머니 역할수행에 대한 자신감 및 만족도의 관계

이영은,강양희,박혜선,황은주,문미영 고신대학교 전인간호과학연구소 2003 전인간호과학연구 학술모음집 Vol.2 No.-

Method : The subjects of this study were 300 mothers of infant at the age of 1-12 months who visited well baby clinic in 4 hospitals in Busart city and Kyoung-Nam province. Final analysis was performed in 293 cases. Seven cases was excluded in this study because of its inappropriate data collection. The data was collected from 1st July to 15th August 2002. The questionnaries which were fill-up by mother were collected. Infant temperament was measured by using the tool of "what my baby is like''(WBL) which was developed by Priham et. al.(1994) and translated by Bang(1999). The scale of postpartum self evaluation which was developed by Lederman et al( 1981) and translated by Lee( 1992) was used for the confidence and satisfaction of maternal role. All statistical analyses were performed using SPSS-PC for window, version 10.0: frequency, percentage, minimum, maximum, mean, SD, t-test, ANOVA, Post-hoc test(Scheffe's test), Pearson Correlation Coefficients. Purpose : This study was intended to search the relationship between perception of the infant temperament in mother of infant at the age of 1-12 months and maternal confidence and satisfaction in performing maternal role, and to submit a basic data to establish a nursing intervention program which is helpful for determination of infant development and performing maternal role promotion by identify variables associated with infant temperament perception of the infant temperament was 6.17±1.04, and mother recognized her infant as positive. The mean score of confidence of maternal role was 2.89±.41 and this revealed in an average level. The mean score of satisfaction of maternal role was 3.29± .51 and this revealed in a higher level. There was a weak significant positive correlation between the score of maternal perception of infant temperament and confidence of maternal role(r=0.176, P= .003), but there was no significant correlation between satisfaction of maternal role(P> .05). It revealed the more maternal perception of the infant temperament as positive, the higher confidence of maternal role. There was a moderate significant positive correlation between confidence of maternal role and satisfaction of maternal role(r=0.410, P= .000). It revealed the more confidence of maternal role, the higher satisfaction of maternal role. The variables related with the score of maternal perception of infant temperament were the type of delivery (t=-2.600, P= .010), experience of learning baby care(t=2.382, P= .018), maternal perception on baby's health status(F=3.467, P= .033), maternal perception on her health status(F=3.467, P= .027), baby's age(F= .080, P= .028). Conclusion : Our result showed the confidence of maternal role was increased as the maternal perception of infant temperament was positive, and conformed that the confidence of maternal role was also related with satisfaction of maternal role. Prenatal education, type of delivery, baby's age were also related with the maternal perception of infant temperament. So, nursing intervention program of developmental stage maybe necessary in order to help maternal perception of infant temperament as positive, and it will be increased the confidence of maternal role and satisfaction of performing maternal role which was considered as real indicate of achievement of maternal role.

PVC 및 Olefin계 Copolymer의 열안정성에 관한 연구(II) : 열안정 영향 인자 Thermal Stability Factor

송해영,황택성,맹기석,박인환 忠南大學校 産業技術硏究所 1986 산업기술연구논문집 Vol.1 No.2

Several structural factors which governs the thermal stability of poly(vinyl chloride) were investigated by IR and H¹-NMR spectroscopy. PVC-Olefin copolymers having diverse structure were prepared by same reaction conditions such as reaction temperature and comonomer composition. It was found that keto allyl groups in the polymer backbone which were formed through a side reaction show the most pronauncing effect. The content of keto allyl group appeared to increase with the relative amount of olefin comonomers. On the other hand, neither chain branching nor tecticity influenced the thermal stability of copolymer. Also, the content of double bond fromed at chain ends was unrelated to the thermal stability.
