崔耕順 新羅大學校 1981 論文集 Vol.11 No.-

The aim of this study is to reveal how fatherless children compare with intact children in manifest anxiety with a view to indentifying an aspect of father's role in relation with children. The children selected for this study are 313 permanently fatherless children, 391 temporarily fatherless children children and 722 intact children wh are all in the 5th grade attending 8 different elementary shcools in Busan. The tets adopted for this study is Choi Jinseung & Jutae Kang's Korean version of Castaneda A. et al(1956). This study set up the following four assumptions: (1) The frequency of abnormal anxiety manfestation of fatherless children would be higher than that ofintact children. (2) The frequency of abnormal anxiety manifcstation of temporarily fatherless children would be higher than that of permanently fatherless children. (3) The frequency of abnormal anxiety manifcstation of fatherless boys would be higher than that of fatheress girls. (4) The frequency of abnormal anxiety manifestation of more permanently fatherless children would be higher than that less permanently fatherless children. The results of the test and its analysis are summarized as follows: 1. It turned out that the assumption(1) is true. Thus, it can be concluded that 'fatherlessness' is a critical factor that influences children's manifest anxiety. 2. There was no difference in the frequency of abnormal anxiety manifestation between temporarily fatherless children and permanently faterless children. But it is noted that temporary fatherlessness turned out to cause deeper anxieties. 3. There was no significant difference between fatherless boys and fatherless girls. This means that fatherlessness influences children regardless of their sexes. 4. The length of period of fatherlessness turned out not to be correlated with the frequency of abnormal anxiety manifestation.

兒童發達에 따른 父親의 役割 : 兒童의 攻擊性·依存性·社會性을 中心으로

崔耕順 新羅大學校 1986 論文集 Vol.21 No.-

The following study treats the role of the father in childhood development. Through field studies of social and emotional behaviour, I observed how the presence of the father influences the personal and social development of children. Before beginning my research in Japan, I conducted a similar study on Korean children. Its results left me with several un answered questions. These and the study itself provided a basis from which I began my research in Japan. In the future, these two separate studies should allow me to compare the father-child relationships in Korea and Japan. I focused on aggression, dependency and sociability of children between the ages of three, four and five, a period considered to be formative in a child`s social development. Employing the statistical data taken from my field work, I first compared the differences between children in families with fathers and those that were fatherless. Next, I contrasted the child-rearing patterns of married parents with those of single mothers. Lastly, I studied the behaviour of fathers toward their children. I classified these observations according to the structure of the family-those with and those without fathers-, the sex and the age of the children. My conclusions are the following: (1) the behaviour of the children On the whole, there was no significant difference in aggression, dependency and sociability between the group of children without and with fathers. However, in detail, a remarkable difference became apparent. 1. Aggresion - In the fatherless families children tended to express their aggressions in indirect and verbal ways. Boys in families with fathers tended to express aggression physically. - The lower the age of children in two-parent families the more frequent they expressed their aggression toward objects. Boys tended to be more aggressive than girls. - In the group of the four-year olds of fatherless families, verbal indirect aggression and aggression toward objects was high. There was no significant difference between boys and girls, but boys tended to grow more aggressive with age. 2. Dependency - The children of fatherless families tended to be very dependent and grew increasingly so with age. - In two-parent families, there was an indirect relationship between age and dependency. Girls tended to be more dependent than boys. - The four-year olds of fatherless families tended to be especially dependent. On the whole, the sex of the child made no difference. But the three-year old girls tended to want attention and physical contact. 3. Sociability - Children of fatherless families tended to be the most participant while those with fathers were more affable. - Children with fathers tended to grow increasingly role taking and affable with age. - Both boys and girls without fathers were very participating. Girls grew more cooperative and less affable with age. Conclusion In the two groups observed, there were differences in the children`s behaviour and the child-rearing patterns. The relationship between fathers and children was weak. Overall, children were cooperative with their mothers. This study clearly demonstrates that fathers and mothers have different influences on their children. The parents had a direct influence on the patterns of aggression and dependency in their children`s behaviour. Because the roles of the father and mother have become less rigid in modern times, I was unable to establish a causal relationship between the father`s influence on the children, distinguished from the mother`s. That is, which behaviours could be attributed to the father`s influence and which to the mother`s remained unclear. While the fathers role in the family seems important, one can not negate the possibility of having this role played by another person. I have shown in this study that whether a child has two parents or one directly influences his or her development. My study does not yet clarify whether or not a parent`s role can be substituted by another person.

In this study, we determined the effect of the mulberry leaf powder on blood lipid metabolism and liver function improvement of mice fed a high fat diet. The mulberry leaf showed a moisture content of $10.74{\pm}0.56%$, ash $9.67{\pm}0.56%$, crude protein $25.24{\pm}1.02%$, and crude fat $2.66{\pm}0.08%$. In the group with high fat diet supplemented with mulberry leaf powder, serum low-density lipoprotein (LDL-cholesterol) and total cholesterol levels were significantly lower (p<0.05); also, serum phospholipid and aspartate amino transferase (AST) levels were significantly lower (p<0.05). Serum insulin and leptin levels were high in mice fed a high fat diet; however, addition of mulberry leaf powder 10% in the diet had no significant effect on blood insulin and leptin control. The results of the study suggested that various plant sterols in mulberry leaf improve lipid metabolism and liver function in ICR-mice.

Since Korean ancient times, powder of Rosa rugosa Thunberg has been used as a folk remedy. This study was conducted to verify the effects of Rosa rugosa Thunberg powder on in vitro antioxidant properties and serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. In the case of Rosa rugosa Thunberg powders, measurement of TPC, ABTS radical scavenging activity of trolox, DPPH radical scavenging activity, and measured value of FRAP were higher in ethanol extract than water extracts. For LDL-cholesterol concentration, mice fed 10% powder of Rosa rugosa Thunberg with high-fat diets showed a high numerical value compared with other groups (p<0.05). When testing for triglyceride concentrations in blood, mice fed 10% and 20% powder of Rosa rugosa Thunberg with high-fat diets showed the lowest numerical values (p<0.05). When testing for blood insulin concentrations, the high-fat diet group showed higher levels than compared to the control group (p<0.05). When testing for blood leptin concentrations, the high-fat diet group was $5.88{\pm}3.53ng/dL$, whereas mice fed 10% powder of Rosa rugosa Thunberg with high-fat diets showed a blood leptin level of $10.36{\pm}5.96ng/dL$ (p<0.05). Therefore, results prove that powder of Rosa rugosa Thunberg reduces triglyceride concentrations in the blood, and could be used as an excellent natural antioxidant in the future.

최경순 이화여자대학교 특수교육학회 2004 이화교육논총 Vol.14 No.-

For this study middle school science instructions were observed and analyzed. It has done how the science instrucions were interacted to improve students'learning. In the middle school science instruction, and in the science instruction process, specific characters of the teachers and students' interaction were found out. This study is for drawing the characters of the interaciton between teachers and students' and facilitating the desirable instrutions. For this study, four teachers of coeducatonals in Kyung-ki province were selected at discretion. then each teacher's instruction was recorded twice and was copied all the contents of observation. The aspects of instrctional contents, instructional methods and instructional circumstances are considered on this study. How teachers and students are interacted in schience instruction was analyzed. The conclusions are as follows. In the aspect of instructional contents, there are several good ways to interact. First, reorganizing the contents of textbooks is much better than just teaching original contents of the textbook. Second, connecting science with students' ordinary life is also a good way. Finally, teachers'using thoughts, understandings and meta questions to read students' responds make strong interaction. In the aspect of instructional method, using audio-visual material in instuciton is better than style one. Because the former can make students participate in instrction positively, the interaction strongly occurs. In the aspect of instructional circumstances, the instruction which contributes to democratic atmosphere showed stronger interaction than opposite case because such instruciton respected students' opinion in maximum.
