The present study set out to investigate influencing factors on family strength. The sample consisted of 249 male and female married adults who were in the class of social welfare in S cyber university. Analysis revealed that married adults' family strength level was 3.86(above the moderate). Among variables, marital status, religion, income, economic problems couple conflict, conflict with mother-in-law, children's problem, family of origin experiences were associated with family strength. Regression analysis revealed that family cooperation and harmony of family were associated with family strength among 8 sub-factors : overall emotional health of family, conflict resolution, acceptance of separation and loss, permission to others, harmony of family, family cooperation, independence in extended family, power balance in family. These findings highlight the collective characteristics of Korean family and traditional values emphasizing the harmony influences the family strength through the generation.

The purpose of this study was to prove the effects of parents' family-of-origin experiences on their parenting efficacy among 260 parents with children aged between 3 and 7. The results were as follows. First, depending on parents' gender, with children aged between 3 and 7, both parents were found to positively perceive each factor in their family-of-origin experience and parenting efficacy. Second, fathers showed differences based on their income satisfaction and their mothers' employment status in their family of origin. Mothers showed differences in parenting efficacy according to their age, monthly average family income, and economic status in their family of origin. Third, both parents' experiences with their family of origin were correlated with their parenting efficacy. Fourth, family-of-origin health was found to be the most significant family-of-origin variable influencing parents' parenting efficacy. Wealth and experience of triangulation were found to be the influential factors common to both parents. Fathers' experiences of acceptance from their parents in their family of origin was a predictive factor of parenting efficacy. In contrast, in the case of mothers with more than two kids, when their family of origin was an extended family and when the mother in their family of origin had stayed at home, they showed higher parenting efficacy in their current parenting.

Samples are often found to be too heterogeneous to be explained by a one-parameter family of models in the sense that the implicit mean-variance relationship in such a family is violated by the data. This phenomenon is often called over-dispersion. The most frequently used method in dealing with over-dispersion is to mix a one-parameter family creating a two parameter marginal mixture family for the data. In this paper, we investigate performance of estimators such as maximum likelihood estimator, method of moment estimator, and maximum quasi-likelihood estimator in negative binomial and beta-binomial distribution. Simulations are done for various mean parameter and dispersion parameter in both distributions, and we conclude that the moment estimators are very superior in the sense of bias and asymptotic relative efficiency.

This study investigated various alternatives for childcare among dual-earner families and discussed implications for public policy development. Eight employed married women and two of their husbands were interviewed about work-family balance. All the interviewees complained that taking cue of the children in dual-earner families is a challenge. They resort to all available alternatives because public childcare support is insufficient and inadequate. There were five different types chilcare: extended family network, public and private institutions, paid help (nannies), rearranging work schedules, and training their children to take cue of themselves. However, all these alternatives entail various problems. More and better childcare facilities and programs should be built and after-school programs should be designed. On the other hand, parents should also make more effort to prioritize children's needs in finding a balance between work and family.

This study explores the overall attitudes of family life used data from dual-earner wives(N=773) who contribute to household economics. The major hypothesis of this study is that employed wives are more likely to be equal in performing their roles at home than full-time homemakers. However, a pattern of asymmetry exists concerning the role performance of wives regardless of their employment The specific findings are as follows : (1) Wives indicate the instrumental and the dual(mixed the traditional value with the developmental value) perceptions of marriage. (2) It is not equal in the distribution of family resources and the procedure of decision-making among couples. (3) The household labor is mainly performed by wives. (4) Wives are mainly responsible for child-rearing and indicate the inconsistent perception of mothering From the findings study suggests that : (1) Future research might investigate the reason of low family contribution among employed wives (2) The egalitarianism (role sharing) in household labor and child rearing might be extended. 93) women might be educated to pursue an independent life.

A case report of a post-traumatic syringomyelia in a 29-year old male, developed 15 years after an L1 burst fracture, is presented. On preoperative MRI, the syrinx extended cephalad above the fracture site through the whole thoracic and cervical cord. Serial myelo-CT was performed to evaluate the dynamics of CSF. It was managed by lysis of the arachnoid adhesions, syringosubarachnoid shunt, and expansile duraplasty. After surgery, the patient's symptoms improved, and marked decrease of the syrinx was seen on postoperative MRI. The pathophysiology, the role of preoperative diagnostic methods especially serial myelo-CT, and the contmporary management modalities for posttraumatic syringomyelia is reviewed along with the pertinent literature.

The purpose of this study was to investigate the effect of weekend forest healing programs using urban forest on family cohesion and family relationship improvement and parental satisfaction with programs. 21 families (65 people)participated in the weekend forest healing program in Incheon Grand Park from April to August 2018. The program using family forest experience activity and forest healing therapy was newly constructed and implemented with 4 times 8 hours for 2 hours each week. The results of this study is that weekend forest healing programs for family gave a positive effect on family cohesion and family relationship, and parents' satisfaction showed high satisfaction in most items. Therefore, we concluded that forest healing activities are suitable for effective healing activities in modern society where functions such as family cohesion and emotional bond are recognized as important by improving family cohesion and family relationship. Further research should be extended to different types of families, and the development of diverse and interesting family-experience forest healing programs that reflect family needs should continue.

Background: TAP1 and TAP2 are two ABC transporter genes located within the class II region of the human MHC. Their protein products form a heterodimer whose function is to transport peptides from the cytoplasm into the endoplasmic reticulum. This study was performed to examine the polymorphism of TAP genes and the distribution of HLA-TAP haplotypes in the Korean population through family analysis. Methods: The subjects used in this study were 50 healthy Korean families consisting of 233 individuals. TAP1 (codons 333 and 637) and TAP2 (codons 379, 565, 577, 651, 665, and 687) typings were carried out by the PCR-restriction fragment length polymorphism (RFLP) method. HLA-DRB1 and DQB1 genotyping results from a previous study were used for HLA-TAP haplotype analysis. Results: The number (gene frequency) of TAP1 and TAP2 alleles detected were 3 for TAP1 (A 81.5%, B 17.0%, and C 1.5%) and 8 for TAP2 (A1 32.0%, A2 12.5%, B 34.0%, Bky2 6.5%, C 7.0%, D 3.0%, E 4.5%, and G 0.5%). Eleven TAP1-TAP2 haplotypes were observed with $frequency{\geq}1%$, among which 4 haplotypes (A-B, B-A1, A-Bky2, and C-E) showed weak but significant positive linkage disequilibrium (P<0.05). When DRB1-DQB1 haplotypes were extended to TAP1 and TAP2 loci, much diversification of haplotypes was observed: 19 different DRB1-DQB1 haplotypes formed 58 different haplotypes extended to TAP1 and TAP2 loci. These results add more evidence to the view that recombination hotspot is present within and around TAP gene region. Conclusion: The allele frequencies of TAP1 and TAP2 genes and the distribution of TAP1-TAP2 and HLA-TAP haplotypes were studied in Koreans based on a family study.

Let X be a nonempty set and $\mathcal{F}$(X) be the set of nonempty finite subsets of X. The paper deals with the extended metrics ${\tau}:\mathcal{F}(X){\rightarrow}\mathbb{R}$ recently introduced by Peter Balk. Balk's metrics and their restriction to the family of sets A with ${\mid}A{\mid}{\leqslant}n$ make possible to consider "distance functions" with n variables and related them quantities. In particular, we study such type generalized diameters $diam_{{\tau}^n}$ and find conditions under which $B{\mapsto}diam_{{\tau}^n}B$ is a Balk's metric. We prove the necessary and sufficient conditions under which the restriction ${\tau}$ to the set of $A{\in}\mathcal{F}(X)$ with ${\mid}A{\mid}{\leqslant}3$ is a symmetric G-metric. An infinitesimal analog for extended by Balk metrics is constructed.

R-curve based on the size effect law previously developed for geometrically similar specimens (geometry type III) is extended to geometries with variable depth (geometry type I) as well as with variable notch (geometry type II), where the R-curve is defined as the envelope of the family of critical strain energy release rates from specimens of different sizes. The results show that the extended R-curve for type I tends to be the same for different specimen configurations, while it is greatly dependent on specimen geometry in terms of the initial crack length. Furthermore, the predicted load-deflection responses from the suggested R-curve are found to agree well with the testing results on concrete and rock materials. Besides, maximum loads for type II specimen are predicted well from the extended R-curve.
