This study examined how the resources from work, family and community lowered family-to-work conflict (FWC) and enhanced family-to-work facilitation (FWF) of employed women with a child younger than 18 years old in order to provide empirical support for the Korean government's effort to create a family-friendly community as a way to help employed mothers balance work and family life. Information from 608 employed mothers living in 45 different communities were extracted from the 4th-wave of the Korean Longitudinal Survey of Women and Families in 2012, while community resources indicators were selected from the 2012 database of the Korean Statistical Information Service. Findings from the HLM analysis were as follows. First, there were significant variation in FWC and FWF among employed mothers depending on the communities they resided in. Second, work satisfaction, representative of work resource, relieved FWC and enhanced FWF, but spousal support, which represents family resource, affected neither FWC nor FWF. Third, community resources, as represented by family-friendly environment and frequent volunteering by community residents, lowered FWC but failed to enhance FWF. Lastly, family-friendly community resources served to mitigate the negative relationship between work satisfaction and FWC. This study is meaningful in that it provided empirical evidence for the contribution of community resources to work-family balance of employed mothers.

The fiber wall filling(FWF) technology, which is based on Precipitatin of fillers in the micropores of the cell wall structure of never-dried chemical pulp fiber, has been developed to improve filling and loading process in papermaking. In presenting FWF technique here, micropores of pulp fiber are first impregnated with an ionic solution of water soluble salt and consecutively impregnated with the second salt solution. This procedure generates an insoluble precipitate within the micropores of cell wall by chemical interaction of these two ionic salt solutions This is the first attempts to use FWF technology for the quality of waste paper grade which is recycled in papermaking, even though this FWF technology has been impressively improved for never-dried chemical pulp in filling and loading process of papermaking. The precipitated amount of CaCO$_3$ and SrCO$_3$ reached 5-6% and 4-5% of the waste paper weight respectively, which was measured by ash content of the burned waste paper fiber. On the other way the precipitated amounts of those materials impregnated into never-dried chemical pulp fiber have reached 17-18% and 16-18% respectively. The micropore loading technique gives optical and physical properties to the handsheets formed with celt-wall-filled fibers which are better than those handsheet properties resulting from conventional loading. The papers made from the cell-wall-filled pulps are stronger than those with the customary location of filler between the fibers.

We experimentally measured the dependence of FWM efficiency on channel spacing for G.652, G.653, G.655 optical fiber with various dispersion values and compared the results with analytical results. Also, we investigated the dependence of XPM efficiency on channel spacing and dispersion in pump-probe experimental configuration.
