The purpose of this study was to investigate the relationships between parental childreating behaviors and parental personality, and children’s emotional intelligence. The subjects included 223 children from kindergarten to 6th grade and their parents. The results were as follows: Firstly, children’s Emotional Intelligence(EI) showed sex difference and age difference between two grade-groups(kindergarten~3rd grade, 4th~6th grade). the age-differences being more distinct in other-related EI than in the self-related : Secondly, parental personality explained parental childrearing behaviors better in higher-grade groups than in lower-grade groups, maternal personality predicting maternal childreating behaviors better than paternal personality predicting the paternal childreaing behaviors; Thirdly, childrearing behaviors explained childern’s self-relate EI better than the other-related : Finally, parental personality revealed greater predictive power of children’s EI in higher-grade groups than in lower-grade groups, better explaining sel-related EI than the other-related. Several suggestions were made concerning future EI studies.

Pu-lei is a well-known translator in Chinese literature. He had delivered his experience, knowledge and paternal love to his son who was studying abroad, by hundreds of letters from 1954 to 1966. These letters are appreciated as the perfect expression for paternal love and concerns. Although he had experienced both cultures of the West and the East, his lessons for son are rooted in the oriental‘sprit training’. What he emphasized in his letters is that one should put sound personality first than merely enhancing abilities. Especially, he valued the recreation from meditation and living up to one's belief. Furthermore, he had taught his son to observe the properties, to manage time, and pride of his country and patriotism. The modern family education has overlooked the enhancement of human nature. The egoistic and jaundiced parental love and over-protectiveness led the disorder and the absence of morality today. In this point, the lessons from Pu-lei's letter will give us important suggestions.

This study was conducted to identify the taxonomic differences in the characteristics of Rhodeus ocellatus and Acheilognathus yamatsutae during their early life history via an interspecific hybridization experiment. Results showed that the hatching rates of the cross-bred eggs were 60% for cross OY (R. ocellatus ♀×A. yamatsutae ♂) and 70% for cross YO (A. yamatsutae ♀×R. ocellatus ♂). The dorsal fin rays of YO were similar to those of R. ocellatus. The hybridization test of A. yamatsutae and R. ocellatus living in the same water stream revealed that no interspecies reproductive isolation occurred. OY and YO showed similar maternal and paternal characteristic. The juvenile of OY did not resemble both paternal and maternal fin rays, indicating a difference. The hatching larvae of the hybrids showed the morphological characteristics of their parents but varied in terms of the shapes of their parts.

Relationships of breeding values of sires for first lactation milk yield with pedigree information or indices were examined to identify the optimal criteria of selecting young dairy bulls for future use in artificial insemination (AI). Records of performance data on 1087 crossbred daughters (Holstein - Friesian, Jersey and Brown Swiss with Hariana) of 147 sires, generated at Livestock Production Research (Cattle and Buffaloes) Farm, IVRI, Izatnagar, U.P., during 1972 - 1995 were used to obtain the estimates of sire's breeding values (EBV) using the Best Linear Unbiased Prediction Procedures. The correlations between young bull's EBV and the dam's first lactation milk yield was non-significantly different from zero. However, the young bull's EBV was negatively and significantly related (r = - 0.275 ; P < 0.05) to the dam's best lactation milk yield, suggesting that the selection of young dairy bulls from high yielding elite dams is not a suitable criteria for genetic improvement. The correlations of sire's and paternal grandsire's EBV's with young bull's EBV were high and positive (0.532, 0.844; P < 0.01). The maternal grandsire's EBV was positively but non-significantly related to grandson's EBV. The pedigree index incorporating dam's milk records and sire's EBV's showed a negative and non-significant correlation with young bull's EBV. However, the correlation of a pedigree index $(I_3)$ combining information on sire's and paternal grand-sire's EBV's with young bull's EBV's was considerably high and positive (0.797; P < 0.01). The regression coefficients of young bull's EBV on pedigree index $I_3$, was higher than those on other pedigree information. These results revealed that there was no advantage in basing selection on dam's performance or maternal grand-sire's EBV and that sire's and paternal grandsire's EBV's were reliable pedigree information for selection of young dairy bulls for future use in AI.

This study was investigated to test whether paternal DNA that was destined for degradation was properly licensed by testing for the presence of mini-chromosome maintenance protein (MCM) 7 and origin recognition complex (ORC) 2 in the paternal pronuclei. ORC2 is one of the first licensing protein to come on and MCM7 is one of the last licensing protein to come on. Zygotes were prepared by injection of control and treated sperm injection (ICSI). To control for DNA breakage, epididymal spermatozoa were treated with DNase I to fragment the DNA, then injected into oocytes. The presence of MCM7 and ORC2 in the pronuclei of mouse zygotes was tested by immunohistochemistry, just before the onset of DNA synthesis, at 5 h after fertilization, and after DNA synthesis began, at 9 h post fertilization. We found that in all cases, both MCM7 and ORC2 were present in both pronuclei at 5 h after sperm injection, just before DNA synthesis began. This indicates that no matter how extensive the DNA damage, recruitment of licensing proteins to the origins of replication was not inhibited. Sperm DNA fragmentation does not prevent licensing of DNA replication origins. Furthermore, the embryo recognizes DNA that is damaged by nucleases. Our data indicate that the one-cell embryo does harbor a mechanism to prevent the replication of severely damaged DNA from spermatozoa, even though the embryos do not undergo classical apoptosis.

Background: Retinoblastoma is a rare malignant intraocular neoplasm. About 90% of cases feature a germline mutation in the RB1 gene and these will develop retinoblastoma during their early childhood. An association between mutations in germline cells and aging has been demonstrated. This suggests a higher incidence of childhood cancer including retinoblastoma among children of older parents. Materials and Methods: In the present study we aimed to determine the association of paternal and maternal age with an increased risk of retinoblastoma in a case-control study in Iranian population. The study was carried out on 240 persons who were born during 1984-2012 in Mahak and Mofid hospitals in Tehran, Iran. The statistical analysis included studying the mean age of parents and in order to know whether parental age of patients is different from parental age of control group, (t-test) compare averages test is used perfectly. By binary logistic regression, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Results: The results of statistical analysis including the study of mean parental age by the use of (t-test) compare averages test showed a significant difference between parental ages of patients and controls. Logistic regression showed that coefficients were significant for maternal but not paternal age. Conclusions: Our findings indicate that advanced maternal age can increase the risk of retinoblastoma in offspring, but the paternal age has no significant effect.

Pedigree data were used to predict the performance of 1,166 imported Americas Brahman breeder cattle, composed of 104 bulls and 1,062 heifers with an average age of 24.4 months (range of 17 to 40 months). A total of 13 full sib, 10 maternal half sib, and 228 paternal half sib groups were identified, each with average group size of 2.08, 2.00, and 4.49, respectively. Only 758 (64.9% of total) imported cattle were found to have at least one ancestor with expected progeny differences (EPDs) reported in the Spring 1995 Brahman Sire Summary. Moderate average accuracy values of .71, .69, .52, and .52 for birth weight, weaning weight, yearling weight, and maternal milk, respectively, were noted for EPDs of the ancestors. Prediction equations were derived by multiple regression analysis of available EPDs of sire, paternal grand sire, and maternal grand sire. Based on pedigree indexes that involve various combinations of available ancestral information, the average predicted EPDs (lbs) for imported cattle were $1.76{\pm}0.54$, $14.93{\pm}4.86$, $25.10{\pm}9.50$, and $5.86{\pm}2.08$ for birth weight, weaning weight, yearling weight, and maternal milk, respectively. Significant correlations (p < .05) were also found between sire and son EPDs (+.27) for yearling weight; and between sire and paternal grand sire EPDs for birth weight (+.34), weaning weight (+.51), yearling weight (+.49), and maternal milk (+.55).

This study was designed to develop and lest a structural model for paternal adaplation and family stress in the families with the handicapped children. A hypothetical model was constructed on the basis of family stress theory developed by McCubbin etc. The model included 6 theoretical concepts and 11 paths. For the purpose of the model testing, empirical data were collected from May to August, 1992. The subject of the study constituted 190 mothers whose children admitted in the five special schools and one privale institutes in Seoul and Choong Nam. In data analysis, SPSS PC+ and PC-LISREL 7.13 computer program were utilized for descriptive and covariance structure analysis. The results of lhe study were as follows. (1) Hypothetical model showed a good fit to the empirical data [Chi-square = 21.19 (df = 7, P = o. 003), Goodness of Fit Index=O.986, Adjusted Goodness of Fit Indes=0.946, Root Mean Square lesidual=0.048), Non Normed Fit Index = 0.80, Normed Fit Index=0.91]. (2) The results of Hypothesis testing indicated: 1) Social support(${\gamma}_11=.238$, T=2.352), Family Functioning(${\gamma}_12=.729$, T=5.957) had direct effects on situational definition. 2) life event stress(${\gamma}_23=.284$, T=5.220) had direct effects on the effect of the handicapped chid on the family. 3) Family functioning(${\gamma}_32=-.239$, T= -3.370) had direct effects on paternal adapation. From the above results, the significance of this study can be delineated as follows : The construction and testing of the comprehensive model seem to be the first trial in Korea. The model was supported by empirical dala. Thus it was suggested that model could be adequately applied to framily nusing care with the handicapped.

The purpose of this study was to validate a hypothetical path model of maternal childhood attachment, emotions, parenting behaviors, and child behavioral problems. The research was conducted with 240 sets or mothers and their children 70 mother-child teams from seven counseling organizations including the Children's Counseling Clinic, Community Social Welfare Service Center, and Welfare Service Center for the Disabled in Seoul, Incheon, and Pyeongtaek, and 170 elementary school children from Seoul and their mothers. Consequently, a total of 200 mother-child teams were selected for this study. The data in this study were analyzed with SPSS 12.0 program and LISREL 8.3 program. The result of this study is as follows: (1) Examining the path of paternal attachment and the internalizing and externalizing behavioral problems, it was noted that paternal attachment had the indirect effect of anxiety and over-protection on the path to internalizing problems and the indirect effect of anxiety also noted is that there is a full-mediation of anxiety and over-protection between paternal attachment and the internalizing problems. (2) Examining the path of maternal attachment and the internalizing problems, it was noted that maternal attachment has direct effect on the internalizing problems. Maternal attachment has the indirect effect of self-esteem depression, anxiety and over-protection on the Path, and the indirect effect of self-esteem, anxiety and over-protection. (3) Examining the path of maternal attachment and the externalizing problems, it was noted that maternal attachment has direct effect on the externalizing problems and on the path to the externalizing problems, and maternal attachment has the indirect effect of depression, the indirect effect of self-esteem and authoritarian control, and the indirect effect of self-esteem and depression.

The purposes of this study were to show general trends in the aspects of psychological family environment (parental communication), peer factor, academic performance factor, depression perceived by adolescents and to examine possible changes in such trends in accordance with demographic variables and the family structure environment (parental marital status, family economic status, and parents' education level), and then to determine the effect of these variables on adolescents' depression. The subjects were 1009 middle and high school students in Seoul and Gyeonggi province. The main results were as follows: 1) Paternal communication was significantly lower in technical high school students, divorced/ separated parents, and families of lower economic status. Maternal communication was significantly lower in male students, divorced/sepa-rated parents, and families of lower economic status. Academic performance problems was significantly higher in males, technical high school students, divorced/ separated parents, families of lower economic status, and a less educated father. Peer relations was significantly lower in students of divorced / separated parents, and of families of lower economic status. Depression was significantly higher in technical high school students, divorced / separated parents, and families of lower economic status. 2) In the case of male students, paternal communication had both a direct and an indirect negative effect through peer relations on depression, while academic performance problems had both a direct and an indirect positive effect through peer relations on depression. Both peer relations and maternal communication had a positive and a negative direct effect on depression. School grade had both a direct and an indirect negative effect through paternal communication on depression. Parental marital status(divorced or separated) had both a direct and an indirect positive effect through academic performance problems on depression. Family economic status had only an indirect effect on discussed.
