While child care policy has mainly focused on the financial support for child care centers, the Ministry of Health, Welfare and Family Affairs recently announced the introduction of a child care allowances. The purpose of this study is to investigate how mothers and directors of child care centers perceived this child care allowance. One hundred and seventeen directors and one hundred and fifty six mothers in the Seoul, Kyunggi-Do, and Cheonbuk-Do areas participated in the survey. The results demonstrated that both the mothers and the directors of child care center exhibit more differences than similarities in terms of their views of child care allowances. Moreover, the perception on some issues of child care allowance differed significantly depending on the types of child care center in question, the mother's economic participation or family income. Issues of importance to the successful introduction of a child care allowance system were also discussed.

C. Vetro [4] gave the concept of weak non-Archimedean in fuzzy metric space. Using the same concept for Menger PM spaces, Mishra et al. [22] proved the common fixed point theorem for six maps, Also they introduced semi-compatibility. In this paper, we generalized the theorem [22] for family of maps and proved the common fixed point theorems using the pair of semi-compatible and reciprocally continuous maps for one pair and R-weakly commuting maps for another pair in Menger WNAPM-spaces. Our results extends and generalizes several known results in metric spaces, probabilistic metric spaces and the similar spaces.

In this study, we analyzed consumers' extra willingness-to-pay for the organic farmed laver, which recently is related to the increased interests in health. Survey questionnaires, which are targeted the urban consumers and based on the equivalent surplus concept, were intended to calculate extra willingness-to-pay for the organic farmed laver. Payment card format was used as the questionnaires type and tobit model was used for the analysis. Variables used for the analysis are sex, age, region, occupation, number in family and income. The results were that the consumers had extra willness-to-pay of 17.16% on average for the eco-friendly organic farmed laver. The higher the income and the more the family number, the customers had more extra willingness-to-pay.

Family with sequence similarity 189, member B (FAM189B), alias COTE1, a putative oncogene selected by microarray, for the first time was here found to be significantly up-regulated in hepatocellular carcinoma (HCC) specimens and HCC cell lines. mRNA expression of COTE1 in HCC samples and cell lines was detected by reverse transcription-polymerase chain reaction (RT-PCR) and real-time PCR, while protein expression of COTE1 in HCC tissues was assessed by immunohistochemistry. In addition, invasion of HCC cells was observed after overexpressing or silencing COTE1. In the total of 48 paired HCC specimens, compared with the adjacent non-cancer tissues, the expression of COTE1 was up-regulated in 31 (p<0.01). In HCC cell lines, COTE1 expression was significantly higher than in normal human adult liver (p<0.01). Overexpression of COTE1 enhanced HCC-derived LM6 and MHCC-L cellular invasion in vitro. In contrast, COTE1 knockdown via RNAi markedly suppressed these phenotypes, as documented in LM3 and MHCC-H HCC cells. Mechanistic analyses indicated that COTE1 could physically associate with WW domain oxidoreductase (WWOX), a tumor suppressor. COTE1 may be closely correlated with invasion of hepatocellular carcinoma (HCC) cells and thus may serve as an effective target for gene therapy.

FAM176A (family with sequence similarity 176 member A) is a novel molecule related to programmed cell death. A decreased expression of FAM176A has been found in several types of human tumors in including lung cancers. In the present study, we investigated the biological activities of FAM176A on the human non-small cell lung cancer cell line H1299 cells. We constructed a recombinant adenovirus 5-FAM176A vector (Ad5-FAM176A) and evaluated the expression and anti-tumor activities in vitro. Cell viability analysis revealed that the adenovirus-mediated increase of FAM176A inhibited the growth of the tumor cells in a dose- and time-dependent manner. This inhibitory effect was mediated by both autophagy and apoptosis that involved caspase activation. In addition, cell cycle analysis suggested that Ad5-FAM176A could induce cell cycle arrest at the G2/M phase, all of which suggested that adenovirus-mediated FAM176A gene transfer might present a new therapeutic approach for lung cancer treatment.

The genus Prunus (family: Rosaceae) consists of over 400 plant species and exhibits vast biodiversity worldwide. Given the wide distribution of this genus, its taxonomic classification is important. Anatomical characteristics are conserved and stable and can therefore be used as an important tool for the taxonomic characterization of plants. Therefore, this study aimed to assess and document the anatomical characteristics of the leaf, stem, and seed of P. africana using micrographs and photographs for possible use in the identification, quality control, and phylogenetic analysis of the species. The anatomical sections of a young stem revealed a cortex consisting of isodiametric parenchyma cells, druse crystals, primary vascular bundles, and pith. The mature stem bark majorly consisted of the rhytidome, with the periderm densely arranged in multiple layers; a cluster of stone cells; and sclerenchyma. The leaf sections were hypostomatic, with stomata sizes ranging from 18.90-(22.34)-26.90 × 15.41-(18.40)-21.22 ㎛. The leaf sections showed the presence of characteristic druse crystals, vascular bundles, and mesophyll layers. The pericarp contained the epicarp, mesocarp, and endocarp, with their thickness being approximately 350-400, 300-350, and 30-50 ㎛, respectively. In addition, it contained a seed testa with a thickness of approximately 50-60 ㎛. The morphological and anatomical characteristics observed in P. africana leaves, stems, and seeds in this study could serve as useful data for the taxonomic identification of this species.

Objectives: Cassia occidentalis L. is a weed belonging to the Caesalpiniaceae family. The root of this medicinal plant is used for the treatment of various ailments, including kidney diseases. The present study was aimed at evaluating the nephroprotective effects of HAE of the roots of Cassia occidentalis L. against gentamicininduced renal toxicity in albino Wistar rats. Methods: The renal toxicity was induced by subcutaneous administration of gentamicin at 100 mg/kg in the rats belonging to the disease control and treatment groups from the 4^th to the 8^th day. The rats in the treatment group received HAE of the roots of Cassia occidentalis L. at 67 mg/kg b. w. orally for 8 days, while no treatment was given to the rats in the disease control and plain control groups. At the end of the experiment, renal biomarkers viz; s. creatinine, b. urea, and s. uric acid, were investigated. The histopathological examination of the kidney specimens was also carried out. Results: The results of the present study revealed that renal function biomarkers such as s. creatinine, b. urea, and s. uric acid were significantly reduced in the rats of the treatment group as compared to those of the disease control group. Moreover, the histoarchitecture reports of the treatment group's kidney specimens showed significant improvements. Conclusion: The results suggested that the HAE of Cassia occidentalis L. roots promisingly prevented kidney injury in gentamicin-induced nephrotoxic rats. This effect might be due to improved clearance of gentamicin from the renal tubule and decreased generation of reactive oxygen species (ROS).

The purpose of this study is to establish family life cycle of farm and to analyze changes of economic conditions-income, consumption expenditures, savings, assets, and debts-in farm household according to the family life cycle. Income, consumption expenditures, savings, assets, and debts functions are also estimated by age of household head. The data of Farm Household Economy Survey which was conducted in 1983 by Ministry of Agriculture and Fisheries is used in this study. Among total data of 2000, 1603 are analyzed for mean, percentage, and regression using CRISP Program at Office of Rural Development. The results of study can be summarized as follows; 1) Eight stages of family life cycle of farm are established according to the growth of the first child. They are: Establishment stage, Child bearing and preschool stage, Elementary school stage, Middle and high school stage, College and vocational adjustment stage, Period of children's marriage, Re-adjustment stage, and isorganizing stage. 2) The economic conditions of farm household are significantly fluctuated by family life cycle. Among the eight stages, stage Ⅱ is considered relatively comfortable living period and stage Ⅲ, Ⅳ are the most difficult periods of farm household economy. 3) The estimated functions of income, consumption expenditures, savings, assets, and debts by age of household head are as follows; Y(income) = 2, 354, 832+98,456T-1,036T2(F=11.746) C(consumption expenditures) = 81,876+154,976T-1,552T2 (F=37.272) S(savings) = 2,272,956+56,511T+516T2(F=4.262) D(debts) = 903,929+28,300T-438T2(F=3.339) A(assets) = 200,816+1,213,336T-12,930T2(F=21.069) To carry on a reasonable farm household management, a suitable measure to cope with the desire of family and the economic conditions of farm household should be prepared.

This study attempted to understand awareness for the overall need of family counseling and aims at providing a direction of support for family counseling that is leveled at married immigrant women and their families. To achieve this, this study analyzed data from the 2010 National Multicultural Families Survey, which was conducted by the Ministry of Health and Welfare. Frequency, distribution, and hierarchical multipleregression analyses on demographic variables, Korean language skills, social support, satisfaction of family relations, and experience of family counseling were conducted in view that these were factors that affected awareness for family counseling, with a total of 58,072 immigrant women who came to Korea. The results of this study are as follows: First, Korean language skills, social support, satisfaction of family relations, the study revealed that subjects recognized the need for family counseling as moderate and their Korean language skills were also moderate. Social supporters did not exceed more than two people including from both Koreans and their country natives, and subjects were satisfied with the relationships to their spouse, children, and parents in-law. Second, there were differences in opinion between the nationalities of the married immigrant women regarding the need for family counseling. Third, the following is the result of the influence of the awareness of the need for family counseling based on the demographic variables of the existence or non-existence of Korean language ability, social support, satisfactory family relationships and previous experience of family counseling.
