Purpose - The adjustment of one country's monetary policy can cause the macroeconomic change of other countries. Due to this, this paper attempts to analyze the impact of China's monetary policy on South Korea's exchange rate. Research design, data, and methodology - Based on the flexible-price monetary model, sets of annual time series from 1980 to 2017 are employed to perform an empirical estimation. The vector error correction model is also used to exploit the short-run relationship between both of them. Of course, the South Korea's real GDP, the China's real GDP, South Korea's interest rate, the South Korea's interest rate and the South Korea's monetary supply are treated as independent variables in this paper. Result - The long-run findings reveal that the China's money supply has a negative effect on South Korea's exchange rate. Respectively, the short-run findings depicts that the China's money supply has negative a effect on South Korea's exchange rate. Of course, other variables selected in this paper also have an effect on South Korea's exchange rate whatever positive or negative. Conclusions - As the empirical evidence shows, the China's monetary policy has a negative effect on South Korea's exchange rate whenever in the long run or in the short run.

The purpose of this study was to find out the relationship of attitudes of parents and their unmarried adult child concerning the family value orientation. In addition to this study examined the relationship to child's family value orientation and related variables. The major findings 1) Gender, mother's value of marriage, religion were influential factors on the child's value of marriage.2) Gender and mother's value of sex role were influential factors on the child's value of sex role. 3) Child's gender was only influential factor on child's value of child. 4) Gender, mother's value of filial piety, father's value of filial piety were significant factors which have some effects on child's attitudes toward value of final piety. 5) Gender, mother's value of familism, religion were significant factors which have some effects on child's attitudes toward value of familism. 6) Gender, mother's family value orientation, father's family value orientation were influential factors on child's family value oreintation. In conclusion, this study found that child's gender was the most influential factor on child's family value orientations. And mother's family value orientations had strong effects on children's family value orientations.

The present study investigated the direct and interactive effects of children's temperament and mothers' reactions to hypothetical vignettes of children's aggression on 3- to 6-year-old children's overt aggression (OA) and relational aggression (RA). A total of 317 mothers of 3- to 6-year-old children and 26 teachers from eight day-care centers and kindergartens were contacted. Each mother reported her child's background, assessed her child's temperament and responded to the Mothers' Reaction to Hypothetical Vignettes of Children's Aggression (MRCA) scale. Children's OA and RA were assessed by teachers. Results showed that high levels of children's surgency predicted children's OA and RA. Although mothers' reactions did not predict children's OA and RA directly, significant interactions indicated that mothers' restrictive reactions were more strongly related to children's OA for children with high levels of surgency and low levels of effortful control. In addition, mothers' responsive reactions were more strongly related to children's OA for children with low levels of surgency. This study demonstrates that relative contributions of children's temperament and mothers' reactions differ according to the form of children's aggression. It also shows that certain types and levels of mothers' reactions to children's aggressive behavior can be critical for children with certain types and levels of temperament in developing children's overt aggression. The findings of this study can be applied to building early prevention and future intervention programs for young children's aggression.

The parentage of the horticulturally important pear cultivar 'Niitaka' was confirmed by determining its S-genotypes based on the S-RNase and $PpSFBB^{-{\gamma}}$ genes, and genotyping using simple sequence repeat (SSR) markers. Previous reports suggested that the cultivars 'Amanogawa' and 'Imamuraaki' were the parents of 'Niitaka', although the cultivars 'Chojuro' and 'Shinchu' were also examined as candidate parents, along with two other cultivars. In the present study, the S-genotype of 'Niitaka' was determined to be $S^3S^9$. The $S^9$-RNase of 'Niitaka' was found to be likely inherited from the parent 'Amanogawa' ($S^1S^9$) and the $S^3$-RNase from 'Chojuro' ($S^3S^5$) or 'Shinchu' ($S^3S^5$). Based on the S-genotypes, the cultivar 'Imamuraaki' ($S^1S^6$) had no contribution to the parentage of 'Niitaka' ($S^3S^9$). A total of 67 polymorphic SSR markers were used to further confirm the parentage of 'Niitaka'. Discrepancies were found at several SSR loci between 'Niitaka' and the cultivars 'Imamuraaki' and 'Shinchu', whereas 'Niitaka' inherited alleles from 'Amanogawa' and 'Chojuro' at all SSR loci. Therefore, our findings established that 'Amanogawa' and 'Chojuro' are the parents of pear cultivar 'Niitaka', and not 'Imamuraaki' as previously reported.

Objective: This study examined the effects of mothers' reactions to children's negative emotions on the children's social power through children's emotional regulation ability. Methods: A total of 339 four-year and five- year old preschoolers, and their mother and teachers in Seoul and Gyeongi participated in the study. Data were analyzed by path analysis using AMOS 21.0 program. Results: The results were as follows: First, mothers' reactions to children's negative emotions were significantly related to children's emotional regulation ability and social power. Also, children's emotional regulation ability was significantly associated with children's social power. Second, mothers' reactions to children's negative emotions had indirect effects on social power - prosocial leadership and social dominance-through children's emotional regulation ability. Conclusion/Implications: The results of this study revealed the mediating role of children's emotional regulation ability between mothers' reactions to children's negative emotions and children's social power. Also, these findings will be helpful in order to understand children's social power and to develop parent education programs.

The S100 family proteins act as inducers of cancer cell apoptosis and inflammatory mediators. This study examined the pro-apoptotic mechanism caused by S100A8 and S100A9 in human FIP1L1-PDGFRα-positive eosinophilic leukemia cells. S100A8 and S100A9 elicited the death of EoL-1 cells in a time and dose-dependent manner. The activation of PDGFRα was suppressed by a decrease in PDGFRα after treatment with S100A8 and S100A9. Cycloheximide, a translation inhibitor, suppressed PDGFRα expression from 1 h to 5 h, and a co-treatment with S100A8 and S100A9 boosted the decrease in expression. The phosphorylation and expression of STAT5 decreased after treatment with S100A8 and S100A9 in EoL-1 and imatinib-resistant (EoL-1-IR) cells. S100A8 and S100A9 induced the chemotaxis of EoL-1 cells but did not affect the chemoattraction of EoL-1-IR. These findings indicate the cell death mechanism due to S100 family proteins and the development of leukemia therapy using S100A8 and S100A9.

Let R be a commutative ring with identity and S be a multiplicatively closed subset of R. In this article we introduce a new class of ring, called S-multiplication rings which are S-versions of multiplication rings. An R-module M is said to be S-multiplication if for each submodule N of M, sN ⊆ JM ⊆ N for some s ∈ S and ideal J of R (see for instance [4, Definition 1]). An ideal I of R is called S-multiplication if I is an S-multiplication R-module. A commutative ring R is called an S-multiplication ring if each ideal of R is S-multiplication. We characterize some special rings such as multiplication rings, almost multiplication rings, arithmetical ring, and S-P IR. Moreover, we generalize some properties of multiplication rings to S-multiplication rings and we study the transfer of this notion to various context of commutative ring extensions such as trivial ring extensions and amalgamated algebras along an ideal.

공공부분 S/W사업은 분리발주가 원칙이고 일괄발주가 예외지만 현재 많은 공공부분 S/W사업은 일괄 발주 사업으로 진행되고 있다. 일괄발주는 SI업체가 S/W업체도 선택하여 입찰 및 개발하기 때문에 발주자가 원하는 품질 좋은 S/W를 선택할 수 없고, 발주자가 S/W를 업그레이드 및 확장할 때 SI업체에 의존하게 되는 단점이 있다. 이런 단점을 보완하고, S/W분리발주를 활성화시키기 위해 지식경제부(구 정보통신부)에서는 S/W분리발주 매뉴얼을 작성하여 보급 및 교육을 하고 있으며, 발주처에서는 품질이 우수한 S/W를 선택하기 위한 S/W분리발주 BMT를 공인된 시험기관인 한국정보통신기술협회(TTA) SW 시험인증센터에서 BMT를 실시하고 있다. 본 논문은 위협관리시스템(TMS) S/W분리발주 BMT를 공인된 국가 시험인증기관인 한국정보통신기술협회(TTA) SW시험인증센터에서 수행한 사례를 기술하였다

From 1996 to 1999, potato-growing areas in Korea were surveyed for identification and distribution of potato scab pathogens. Potato scab was widely distributed in the mass cultivation areas, especially in Jriu island, southern areas of Chonnam and Gyounggi provinces, and the alpine area of Gangwon province. Jeju island was the most affected area by this disease. A total of 55 Streptomyces strains were isolated from potato scab lesions, among which 40 strains were pathogenic on progeny tubers. Among the pathogenic strain, 21 strains were identified as previously described S. scabies, 7 Strains as S. turgidiscabies, and 5 Strains as S. acidiscabies, while 7 strains were observed as having distinct phenotypic properties. These strains were classified into six distinct clusters based on phenotypic characteristics and selected representative strains for each cluster. S. scabies (S33) had grey spores in a spiral chain. Mean-while, S. turgidiscabies (S27) had grey spores, S. acidiscabies (S71) had white spores, S. luridiscabiei (S63) had yellow-white spores, S. puniciscabiei (S77) had purple-red spores, and S. niveiscabiei (S78) had thin and compact white spores, all in a rectiflexuous chain. Pathogenicity was determined by the production of thaxtomin A and homologs of necl and ORFtnp genes. In TLC, representative strains S27, S71, S63, S77, and S78 produced a yellow band that co-migrated with the authentic thaxtomin A. However, thaxtomin A was not detected in chloroform extracts from oatmeal broth culture and Slice tuber tissue of S. luridiscabiei (S63) and S. puniciscabiei (S77) by HPLC analysis. In addition, no homologs of necl and ORFtnp genes in S. acidiscabies (S71), S. luridiscabiei (S63), S. puniciscabiei (S77), and S. niveiscabiei (S78) were detected by PCR and Southern hybridization analysis.
