  • An asteroid specimen was collected in adjacent water of Gisamun, Gangwon-do in the East Sea, Korea at a depth of 170 m by fishing net at May 2013. It was identified as Nearchaster (Nearchaster) pedicellaris (Fisher, 1910) belonging to family Benthopectinidae of order Notomyotida, which was new to the Korean fauna. The genus, family, and order of this species were also new to Korean waters. The partial sequence of mitochodrial cytochrome c oxidase subunit 1 (CO1) was determined for the first time and registered at GenBank.

  • This study aimed to investigate the diversity of the Butyrivibrio group bacteria in goat rumen and its response to garlic oil (GO) supplementation as revealed by molecular analysis of cloned 16S rRNA genes. Six wethers fitted with ruminal fistulas were assigned to two groups for a cross-over design with 28-d experimental period and 14-d interval. Goats were fed a basal diet without (control) or with GO ruminal infusion (0.8 g/d). Ruminal contents were used for DNA extraction collected before morning feeding on d 28. A total bacterial clone library was firstly constructed by nearly full-length 16S rRNA gene cloned sequences using universal primers. The resulting plasmids selected by Butyrivibrio-specific primers were used to construct a Butyrivibrio group-specific bacterial clone library. Butyrivibrio group represented 12.98% and 10.95% of total bacteria in control and GO group, respectively. In libraries, clones were classified to the genus Pseudobutyrivibrio, Butyrivibrio and others within the family Lachnospiraceae. Additionally, some specific clones were observed in GO group, being classified to the genus Ruminococcus and others within the family Ruminococcaceae. Based on the criterion that the similarity was 97% or greater with database sequences, there were 29.73% and 18.42% of clones identified as known isolates (i.e. B. proteoclasticus and Ps. ruminis) in control and GO groups, respectively. Further clones identified as B. fibrisolvens (5.41%) and R. flavefaciens (7.89%) were specifically found in control and GO groups, respectively. The majority of clones resembled Ps. ruminis (98% to 99% similarity), except for Lachnospiraceae bacteria (87% to 92% similarity) in the two libraries. The two clone libraries also appeared different in Shannon diversity index (control 2.47 and GO group 2.91). Our results indicated that the Butyrivibrio group bacteria had a complex community with considerable unknown species in the goat rumen.

  • This study analyzes child and family department curricula at domestic universities and research topics in articles found in related representative domestic journals. Curricula were collected from the web pages of 26 out of 90 departments of 77 universities. Research topics were collected from the Family Environment Research, Journal of Child Studies, and Journal of Korean Association of Family Relations published from 2000 to February 2015. From those journals, the number of articles related to child studies were 1,843 and family studies 1,239. Among those articles, 6,593 keywords related to child studies and 4,748 keywords related with family studies were collected and analyzed. The results of this study were: first, we found four types of curricula provided by Child and Family Departments such as Child Studies, Child and Family Studies, Home Economics Education, and Family Welfare. Second, the identified research topics in child studies were child development, education & childcare, parent education, counseling & therapy, cross cultural study, instrument development, and policy. Family research topics were also categorized by individual family members, child rearing & education, family dynamics & problems, families & culture, work & family, family formation, dissolution & diversity, family practice, family theories & methods, and midlife & later years. We suggest several future careers in child and family studies based on these findings.

  • The purpose of this study is to introduce the evolution of corporate family-friendly policies and programs, a recent business issue throughout the world. In addition, this study suggests implications for a corporate reference guide to work-family policies and programs by providing a comparative analysis of the typical stages of development of U.S. corporate family-friendly policies and programs, and by presenting model initiatives of Korean and American family-friendly companies. Just as technological changes at the time of the Industrial Revolution altered the relationship between workers and their work, more recent technological advances have again transformed this relationship, offering the promise of a society in which work demands a smaller portion of the worker's time and permitting the worker more freedom and control over work conditions. These new work arrangements have the promise of producing a new paradigm for work and family, based on which many industrialized nations have developed family-friendly policies already. Family-friendly policies and programs can be grouped into four discernable stages in the evolution of a corporate work-family agenda. According to these stages, most companies in Korea are in the predevelopment stage or stage 1. Development of scales to assess company family-friendliness is needed to create a family-friendly workplace environment, policies, and programs. It is critical that companies have champions who have the vision to step out in kent, and the determination to ensure that the family-friendly programs are solidly grounded. Companies should develop their work-family initiatives as an integral part of a program for managing diversity focusing on needs of women and minority employees.

  • The family Mesorhabditidae $Andr{\acute{a}}ssy$, 1976 is the most abundant group in Rhabditoidea and occurs all over the world. Over 85 valid species have been reported from Mesorhabditidae; however, only 2 species have been recorded in South Korea. In this study, Bursilla vernalis $Andr{\acute{a}}ssy$, 1982, Mesorhabditis inarimensis (Meyl, 1953) Dougherty, 1955, and M. minuta $Bostr{\ddot{o}}m$, 1991 belonging to the family Mesorhabditidae (Rhabditomorpha), are newly reported from South Korea. Species in this family are distinguished from other rhabditomorphs by a posteriorly located vulva and an unpaired prevulval female gonad. Details of the morphological characters and morphometrics of B. vernalis, M. inarimensis, and M. minuta are described and illustrated based on optical and/or scanning electron microscopy.

  • Mites in the family Veigaiidae, order Mesostigmata, subclass Acari are widely distributed in subsoil habitats. They are mostly free-living and predaceous on small arthropod eggs and larvae, and prefer habitats with rich organic matters including litter and humus layers of forest soil. The genus Veigaia Oudemans, 1905 of the family Veigaiidae (Acari: Mesostigmata) is one of the ubiquitous genera from the Holarctic Region. Until now, only two genera and five species of the family were recorded from Korea. Here we provide a report of the species Veigaia tibbetsi Farrier, 1957 with detailed redescription. Even though V. tibbetsi had appeared in some ecological literature, this is the first record of this species in Republic of Korea. This species was mostly found from pine forest(Pinus densiflora) of northeastern mountainous parts of the Korean Peninsula, in Gangwon and Gyeongbuk Provinces. We provided some ecological characteristics of the family Veigaiidae, which will help to further exploration of acarine biodiversity.

  • We aimed to investigate associations of dietary diversity (DD) with gut microbial diversity and the development of hen's egg allergy (HEA) in infants. We enrolled 68 infants in a high-risk group and 32 infants in a control group based on a family history of allergic diseases. All infants were followed from birth until 12 months of age. We collected infant feeding data, and DD was defined using 3 measures: the World Health Organization definition of minimum DD, food group diversity, and food allergen diversity. Gut microbiome profiles and expression of cytokines were evaluated by bacterial 16S rRNA sequencing and real-time reverse transcriptase-polymerase chain reaction. High DD scores at 3 and 4 months were associated with a lower risk of developing HEA in the high-risk group, but not in the control group. In the high-risk group, high DD scores at 3, 4, and 5 months of age were associated with an increase in Chao1 index at 6 months. We found that the gene expression of IL-4, IL-5, IL-6, and IL-8 were higher among infants who had lower DD scores compared to those who had higher DD scores in high-risk infants. Additionally, high-risk infants with a higher FAD score at 5 months of age showed a reduced gene expression of IL-13. Increasing DD within 6 months of life may increase gut microbial diversity, and thus reduce the development of HEA in infants with a family history of allergic diseases.

  • This study set out from the perception that one should develop and activate differentiated programs from those 5 programs of the Health Family Support Center (family counseling program, family education support project, family affinity culture support project, care support project, diversity family support project) on the subjects (n=299) of residents in G metropolitan city by reflecting the levels of family values, communication between family members and family relationship. To achieve the study purposes above, this study devised research questions as follows: Research question 1. What are the levels of local residents for their family values, communication between family members and family relationship? Research question 2. Is there any difference in demanding family support project programs according to the local residents' family values, communication between family members and family relationship? Following are the results of this study: First, the levels were analyzed to be more than the average (on a maximum scale of 5 points) with local residents' family values (M=3.55, S.D.=.664), communication between family members (M=3.65, S.D.=.669), family relationship (M=3.69 S.D=.584) Second, the necessity levels for family values, communication between family members and family relationship of the group below the average as compared with the group over the average was found to be significantly high in family education support project, family affinity culture support project, care support project and diversity family support project except family counseling program. Accordingly, strategic plans for increasing the participation rate for the programs by the Health Family Support Center and activating those programs could be by investigating in advance the levels of family values, communication between family members and family relationship by each program respectively and differentiating the target level for the program by the group, or by giving preference to the group below the average who have high needs of program necessity when making decisions for the participation preference of the programs.
