This study explored mothers' and grandmothers' perception regarding child rearing practices as overprotective behaviors for first to third grade levels of elementary school. The study was conducted on 202 mothers and grandmothers of first to third grade elementary school students. Questionnaires were made with 40 questions on overprotection behaviors selected from the existing questions for preschooler, high grade elementary students, and youth. The questionnaires were distributed to target subjects to answer how they would perceive when each of question is applied to their lower grade elementary students. Based on the collected responses and the factor analysis, it was found out that the overprotective behaviors were classified into four factors such as "reduction in independence," "over-sensitiveness to safety," "interference in daily life," and "health anxiety." There were significant differences in the perception of the overprotective behavior by the subjects depending on the generations, features of children and mothers. This study focused on the lower grade elementary school students who have been removed from studies due to the lack of intervention measures. It has the implication in that the findings of the study can give the basic data for the development of the scale on overprotective behaviors in lower grade elementary school students.

The purpose of this study was to examine the relationships of mothers exhibiting maternal overprotective behavior and their children's aggression, withdrawal and perceived competence. For data collecting, 339 children attending the fifth/sixth grade of elementary school in Kwangju were involved. The major findings were as follows: First, maternal overprotective behavior related to school learning showed a significant difference due to the children's sex. Furthermore, maternal overprotective behavior related to daily life and school learning showed a significant difference due to the children's grade. Second, maternal overprotective behavior related to daily life showed a significant difference due to the mother's education level. Finally, the result of multiple regression analysis on the effects of the mother's overprotective behavior to the children's aggression, withdrawal, and perceived competence indicated that maternal overprotective behavior related to daily life and school learning was the significant contributing factor. All in all, the variables accounted for 11% of the children's aggression, 11% of the children's withdrawal, and 6% of the children's perceived competence.

Purpose : The keeping warm and avoidance of cold are one of important Korean traditional postpartum care, but sometimes overwarm for example over-bundling, an overheated room or a steam bath cause heavy sweats. I observed and treated three　patients complained of heavy sweats, chills, fatigue, malaise, cold sensation and pain caused by keeping overwarm for postpartum care. Although the symptoms have aggravated, they have maintained keeping overwarm because of a belief of Korean traditional postpartum care. The purpose of these cases studies are to report postpartum hyperhidrosis caused by keeping overwarm and to make a point of keeping the appropriate room temperature and humidity during puerperium. Methods : I observed and treated three patients complained of heavy sweats, chills, fatigue, malaise, cold sensation and pain caused by keeping overwarm for postpartum care. I found that a cause of the symptoms was hyperhidrosis by keeping overwarm, and administered herbal medicine and was to keep the appropriate room temperature. Results : After medication of Herbal medicine(補中益氣湯加味方) and keeping the appropriate room temperature, they were improved. Conclusion : Postpartum care is not to keep overwarm but to keep the appropriate room temperature and humidity.

The purpose of this study was to investigate the effects of family-of-origin experiences(family-of-origin health, parents' marital satisfaction, parents' care, and parents' overprotection) on marital intimacy. Data were collected using the self-administered questionnaire method by Internet Survey of 480 married men and women. The results showed that first, there were significant differences between family-of-origin experiences (family-of-origin health, parents' marital satisfaction, parents' care, and parents' overprotection) and marital intimacy according to sex, educational level, income, and the first-rum child's school level. Second, marital intimacy was positively correlated with family-of-origin health, parents' marital satisfaction, and parents' care, but was negatively correlated with parents' overprotection. Third, the results of multiple regression analyses showed that indicated that the marital intimacy of married men and women were influenced by education level, income, the first-born child's school level, and family-of-origin health.

Objective: The purpose of this study was to explore the pathway from mothers' overprotective parenting to their child's peer play interactions mediated by internalizing problems, that is, social immaturity and withdrawal. Methods: Surveys were conducted on mothers and teachers of 341 children aged three to five. SPSS 22.0 was used to analyze the data using descriptive statistics. Structural modeling analysis was also implemented to test theoretical model using AMOS 21.0. Results: Maternal overprotective parenting, which increased social immaturity of their child, indirectly reduced the child's positive interactions with peers during play. Mothers' overprotection led to a higher level of withdrawal of their child while the effect of children's withdrawal on their peer play interaction was not significant. Because overactive parenting of mothers had no direct effect on peer play interaction, the complete mediation model representing a path from maternal overprotection to children's peer play interaction via their internalizing problems was partially supported. Conclusion/Implications: This study shows that overprotective mothers hinder their child to experience confident and mature manners, and eventually lead their child to be socially unskillful and incompetent. It was suggested to explore more individual characteristics of mothers and children to help overprotective mothers to take a step back.

Objective: This study examined the moderating effect of young children's temperament on the relationship between maternal anxiety and overprotection. Methods: A total of 250 mothers with 5-year-old children responded to online survey questionnaires, which included questions about maternal anxiety, overprotection, and their children's temperament. Results: The results of the study revealed several important findings. First, maternal anxiety had a positive correlation to the overall level of overprotection and all sub-factors. The correlation between young children's temperament and maternal overprotection had different results depending on the sub-factors of overprotection. Second, there was a significant moderating effect of young children's temperament on the relationship between maternal anxiety and overprotection. That is, When the reactivity of a child was low, the positive effect of maternal anxiety on maternal overprotection was greater. Looking at the sub-factors of overprotection, only reactive temperament showed a significant moderating effect in the relationship between maternal anxiety and intrusive overprotection. On the relationship between maternal anxiety and permissive overprotection, reactivity and adaptability had significant moderating effects. Conclusion/Implications: This study showed that mother's overprotection was associated with varying levels of their own anxiety and children's temperament. These findings offer basic knowledge for development of a program for improving parenting behaviors.

Objective: This study aims investigate the moderating effect of mothers' overprotective parenting in the influence of young children's competence, as determined by their temperament, on mastery motivation. Methods: An online survey was conducted on 429 mothers with children aged 3-5. The collected data was analyzed using K-means clustering in SPSS 23.0 and the Process macro Model 2. Results: Children's temperaments were categorized into four types : easy-active temperament, easy-inactive temperament, slow temperament, and difficult temperament. It was confirmed that children's competence directly affected their mastery motivation when they had easy-inactive, slow, or difficult temperament. It was also found that mothers' intrusive control had a direct main effect on object persistence when children had easy temperament, while there was no effect on mastery pleasure. The moderating effects of mothers' anxious protection on the pathway from children's competence to object persistence were significant only among children with a slow temperament. Conclusion/Implications: This study highlights the need for mothers to adapt their parenting behavior to their children's temperament type. The study confirmed partial moderating effects of mothers' overprotective parenting in the influence of children's competence, as determined by their temperament, on mastery motivation.

Purpose: At the beginning of PET/CT, Computed Tomography was mainly used only for Attenuation Correction (AC), but as the performance of the CT have been increase, it could give improved diagnostic information with Contrast Media. But it was controversial that Contrast Media could affect AC on PET/CT scan. Some submitted thesis' show that Contrast Media could overestimate when it is for AC data processing. On the contrary, the opinion that Contrast Media could be possible to affect the alteration of SUV because of the overestimated AC. But it does not have a definite effect on the diagnosis. Thus, the affection of Contrast Media on AC was investigated in this study. Materials and Methods: Patient inclusion criteria required a history of a malignancy and performance of an integrated PET/CT scan and contrast- enhanced CT scan within a 1-day period. Thirty oncologic patients who had PET/CT scan from December 2007 to June 2008 underwent staging evaluation and met these criteria. All patients fasted for at least 6 hr before the IV injection of approximately 5.6 MBq/kg (0.15 mCi/kg) of $^{18}F$-FDG and were scanned about 60 min after injection. All patients had a whole body PET/CT performed without IV contrast media followed by a contrast-enhanced CT on the Discovery STe PET/CT scanner. CT data were used for AC and PET images came out after AC. The ROIs drew and measured SUV. A paired t-test of these results was performed to assess the significance of the difference between the SUV obtained from the two attenuation corrected PET images. Results: The mean and maximum Standardized Uptake Values (SUV) for different regions averaged over all Patients. Comparing before using Contrast Media and after using, Most of ROIs have the increased SUV when it did Contrast Enhanced CT compare to Non-Contrast enhanced CT. All regions have increased SUV and also their p value was under 0.05 except the mean SUV of the Heart region. Conclusion: In this regard, the effect on SUV measurements that occurs when a contrast-enhanced CT is used for attenuation correction could have significant clinical ramifications. But some submitted thesis insisted that the percentage change in SUV that can determine or modify clinical management of oncology patients is small. Because there was not much difference that could be discovered by interpreter. But obviously the numerical change was occurred and on the stage finding primary region, small change would be base line, such as the region of liver which has greater change than the other regions needs more attention.

Most experiments carried out in the previous studies dealt with the highly reinforced concrete beams (RC beams) in case of rehabilitating with external tendon. However, the reinforcing effect of external tendons cannot be clearly analyzed in this kind of RC beams because the rehabilitating tendon quantity for it is too small. By this reason, this study chose the low RC beams rehabilitated with external tendons. Therefore, in this study, 7 test beams were manufactured and flexural behavior tests were performed to assess the reinforcing effect and to find more proper rehabilitating method by external tendon. The reinforcing effect increased according to the quantity of tendons, and was especially added by repairing cracks with epoxy resin. It was shown that the design equations of AASHTO 1994 and ACI-318 did not show a good agreement with test results. The result of this study will be able to be used effectively in finding the more proper rehabilitating method of the damaged RC beams.
