The main purpose of this study was to explore the moderating effects of fathers' current psychological well-being in the relationships between fathers' experienced parenting from the family of origin and their parenting attitudes to their children. The subjects themselves consisted of 370 fifth-and sixth-grade children and their fathers from elementary schools in Seoul and Daegu. Questionnaires containing items related to experienced parenting and the current psychological well-being reported by fathers and fathers' parenting attitudes reported by their children were used. Regression analyses revealed that a fathers' 'independent encouraging' attitude to their children was predicted by a fathers' psychological well-being whereas a fathers' 'acceptance' attitudes was predicted by both a fathers' experienced 'acceptance' parenting and their psychological well-being. Further, a fathers' psychological well-being played a moderate role in the relationship between fathers' experienced 'independent encouraging' parenting from the family of origin and their 'independent encouraging' attitude to their children.

A specimen of Redigobius bikolanus (29.0 mm SL) belonging to the family Gobiidae was collected by a hand net from the estuary of Changgo-cheon (river) in Andeok-myeon, Jeju Island, Korea. This specimen was characterized by having 26 lateral line scales, 7 predorsal scales, 7 transverse scales, anterior oculoscapular canal, preopercular canal, and four black spots between origin of anal fin and lower origin of caudal fin. The morphological characteristics of the specimen well matched those of Redigobius bikolanus previously reported. Thus, we newly add this species to the list of Korean fish fauna and propose its new Korean name, "Jeom-bak-i-mang-duk".

Let V={(x,y,z):f=z$^{n}$ -npz+(n-1)q=0 for n .geq. 3} be a compled analytic subvariety of a polydisc in $C^{3}$ where p=p(x,y) and q=q(x,y) are holomorphic near (x,y)=(0,0) and f is an irreducible Weierstrass polynomial in z of multiplicity n. Suppose that V has an isolated singular point at the origin. Recall that the z-discriminant of f is D(f)=c(p$^{n}$ -q$^{n-1}$) for some number c. Suppose that D(f) is square-free. then we prove that by Theorem 2.1 .mu.(p$^{n}$ -q$^{n-1}$)=.mu.(f)-(n-1)+n(n-2)I(p,q)+1 where .mu.(f), .mu. p$^{n}$ -q$^{n-1}$are the corresponding Milnor numbers of f, p$^{n}$ -q$^{n-1}$, respectively and I(p,q) is the intersection number of p and q at the origin. By one of applications suppose that W$_{t}$ ={(x,y,z):g$_{t}$ =z$^{n}$ -np$_{t}$ $^{n-1}$z+(n-1)q$_{t}$ $^{n-1}$=0} is a smooth family of complex analytic varieties near t=0 each of which has an isolated singularity at the origin, satisfying that the z-discriminant of g$_{t}$ , that is, D(g$_{t}$ ) is square-free. If .mu.(g$_{t}$ ) are constant near t=0, then we prove that the family of plane curves, D(g$_{t}$ ) are equisingular and also D(f$_{t}$ ) are equisingular near t=0 where f$_{t}$ =z$^{n}$ -np$_{t}$ z+(n-1)q$_{t}$ =0.}$ =0.

The purpose of this study was to examine the social support network for divorced single mother families. The data were gathered through in-depth interviews with seven divorced single mothers who had at least one school-age child. Qualitative analysis of data showed that divorced single mothers evaluated themselves based on other people's perception. There were mainly three different kinds of self-images, which were “a competent divorced woman,” “a bad child to my parents,” and “a socially weak person.” We also found that there were two factors that influenced the everyday lives of single mothers: all of them .;offered hardships in living as a divorced woman with children, and they also had to deal with the weakened solidarity with family of origin, relatives, and neighbors. Single mothers shared common problems yet their lifestyles and adjustment strategies were diverse. Therefore, diverse social welfare policies for education and counseling for single mothers are urgently needed to support and empower divorced single mothers.

The purpose of this study was to find a therapeutic intervention for a couple in the pre-divorce stage. We used data from the case study to examine the factors related to marital conflict and enhancements related to the family of origin. Our sample was the couple in pre-divorce stage who has been married for 3 years. The therapeutic intervention methods used were taken from Positive Psychology, Family Systems Theory, Communication Theory, and Solution-Focused Therapy. We counseled the couple once a week for 10 sessions from $5^{th}$ October to $7^{th}$ December in 2010. Our objective was to give a positive perspective on the couple who was in the pre-divorce stage. We also provided clear-cut, practical techniques for responding productively to inappropriate expressions of anger. The couple acquired strategies to make their relationship work more effectively. Finally, the couple set their family goals for adjustment instead of divorce.

Migration studies that assume that decision making is done on an individual basis is overlooking the importance of the family factor. Considering that must people belong to families, it is more appropriate to view migration decision from the perspective of the family. This study analyzes the household migration decision whereby the alternatives are to stay, 10 undertake family migration or to undertake single migration of a member. In developing a conceptual model of household migration decision, it is assumed that the household's objective is to maximize household income which is a function of individual members' earnings. The benefits and costs of household migration and individual migration are identified and the household chooses the migration strategy that maximizes expected household income. When household members have conflicting earning prospects in the potential destination, the household considers single migration of the member with the best earning potentials. However, lone migration by a household member involves cost of family separation which is both monetary and psychic, and this study shows that lone migration is undertaken only when its net gains to the family are greater than the separation cost of the family. The major benefit of choosing single migration is the retention of home base in the place of origin which can serve as an insurance against the uncertainty of obtaining a job in the destination, the benefit that is unavailable in family migration. The conceptual analysis shows how a household's migration decision would depend on its members' economic roles and prospects in the destination. Besides the economic variables, social and life cycle variables of the family translate into separation costs and benefits of migration. This study indicates that one - earner family in low economic status but with good earning prospects and high separation costs is more likely to choose family migration over single migration.

Sin Dae-woo was a scholar representing the Ganghwa School in the late Joseon Dynasty. He was Jeong Je-du's grandson-in-law and also in charge of organizing Jeong Je-du's collection of writings. His three sons had a particularly close relationship with their father, so even when they published a collection of writings after his father's death, the names of the three were combined and marked as Jin-jak-shin. The records they left include Seokcheon Il-seung, who described the history of the family along with the collection of writings, Seongdo Il-rok, a diary of the time of Seongcheon Busa, and many letters exchanged over time. These records draw attention as they contain records of medical life, such as eye diseases that the family suffered, infectious diseases that caused many casualties, and Yakro (distilled herbal essence) that showed records of being used for treatment at the time. In this paper: 1) We examine the medicines, prescriptions, acupuncture, and medication used to treat eye diseases. 2) We carefully examine the epidemic, the responses of the parties to it, and the attitudes of those who stood at the boundary between death and life. 3) We look for clues to the use of Western-origin drugs called Yakro. Intellectuals of the time looked deeper into Lee Kyugyung's book and Seo Yu-gu's book on how they were reflected in Joseon's medical life. In conclusion, in the 18th and 9th centuries, we see that the influential families of the Ganghwa school freely brought in famous acupuncturists, used prescriptions that were included in medical books or not, and used Yakro from western origin that were not traditional methods of Joseon. Thus, we reveal that doctors of the Joseon had the capacity to pursue their medical life more actively and had open-minded exchanges than our existing perceptions.

We previously identified the origin of replication of p703/5, a small cryptic plasmid from the KBL703 strain of Enterococcus faecalis. The origin of replication contains putative regulatory cis-elements required for replication and a replication initiator (RepA) gene. The replicon of p703/5 is similar in its structural organization to theta-type plasmids, and RepA is homologous to a family of Rep proteins identified in several plasmids from Gram-positive bacteria. Here, we report molecular interactions between RepA and the replication origin of p703/5. DNase I footprinting using recombinant RepA together with electrophoretic mobility shift assays confirmed the binding of RepA to the replication origin of p703/5 via iterons and an inverted repeat. We also demonstrated the formation of RepA dimers and the different binding of RepA to the iteron and the inverted repeat using gel filtration chromatographic analysis, a chemical crosslinking assay, and electrophoretic mobility shift assays in the presence of guanidine hydrochloride. Our results suggest that RepA plays a regulatory role in the replication of the enterococcal plasmid p703/5 via mechanisms similar to those of typical iteroncarrying theta-type plasmids.

To obtain antibiotic resistant profiles of Bifidobacterium, minimum inhibitory concentrations (MIC) of 14 antibiotics for 93 Bifidobacterium isolates from Korean intestine origin were determined. All strains tested were sensitive to chloramphenicol, rifampicin, and amoxicillin, whereas resistant to aminoglycoside family, nalidixic acid, and vancomycin. Among vancomycin-resistant strains, 34% were resistant at more than $100\;{\mu}g/mL$, and showed variant resistances toward tetracycline, erythromycin, and penicillin. Their resistances against penicillin, cephalothin, and tetracycline were higher than ten years ago. MIC of ten isolates from commercial yoghurt products were very similar to those of strains from Korean intestine origin, and 20% strains showed resistance at higher than $100\;{\mu}g/mL$ vancomycin. These results indicated patterns of antibiotic resistance against Bifidobacterium from Korean intestine origin and commercial yoghurts were very similar,and prevalence of vancomycin resistance for Bifidobacterium was 20%. To develop new probiotic, antibiotic resistance of vancomycin and risks involved should be evaluated.
