The purpose of this study is to analyze the influences on resource transfers between middle-aged parents and their married children. This study used 2009 data from the National Research Foundation of Korea regarding inter-generational resource transfers and preparation for later life (kfr-2009-c00010). A sample of 1208 households of middle-aged parents with married children was used. The study found that parents provided financial resource transfers to their married children in the following circumstances: where parents received financial resource transfers from their married children, where the household income of parents was high, where the children were younger, and where the children were male. Parents provided instrumental resource transfers to their married children in the following circumstances: where parents received instrumental resource transfers from their married children, where the gender of children was female, where the children were employed, where married children had their own children who were either younger than a preschooler, and where household incomes of married children were high. Parents received financial resource transfers from their married children in these circumstances: where their emotional ties with their children was high, where the household income of the parents was low, where the household income of the married children was high, and where married children had preschoolers. The circumstances in which parents received instrumental resource transfers from their married children were where parents provided instrumental resource transfers and the household incomes of married children were high.

We examined if intergenerational proximity might be associated with upstream financial transfer from adult children to older parents, and whether adult child gender might moderate the association. We considered siblings' proximity to parents, as well as that of the adult child. Prior work conducted in the US and other countries has suggested that children living further from parents might provide financial support to compensate for instrumental support provided more by siblings living closer to parents. Data were drawn from the Korean Longitudinal Study of Ageing (2014). Our analytic sample consisted of older adults 60+ and their children aged 35 and 55. None of the children co-resided with parents. Parental households consisted of either widowed individuals or married couples. For within-family analyses, fixed effects and random effects regression models were estimated. Results suggest first, sons living within a 30-minute distance, or within an hour to two-hour distance provided more monetary support to married parents compared to daughters. Second, contrary to existing findings, greater financial assistance was provided by sons and daughters when no children lived within an hour distance from their parents. For widowed parents living alone, intergenerational proximity was not associated with the amount of financial transfer from adult children.

The purpose of this study was to examine the resource transfer process from female baby boomers to their children who have gotten married or plan on getting married. The following research questions were explored. (1)To what extent have female baby boomers been transferring their resources to their children supporting marriage or vice versa? (2)What are the opinions of female baby boomers on future resource transfer plans to their children? (3)What are the opinions of female baby boomers on supporting themselves in their old age, and those of their children on supporting their aging parents? In-depth interviews were conducted with 11 female baby boomers who were born between 1955 to 1963. A case study research method was used to analyze the interview results. The findings were as follows. First, economic resource was the most common type of resources that the interviewees transferred to their children. Those who could not transfer their economic resources instead transferred their instrumental resources. Second, it was anticipated that the current trend of interviewees' resource transfers would be similar in the future. In other words, those who used to transfer a large amount of economic resources to their children showed their willingness to do the same in the future. Third, the interviewees did not expect support from their children, but rather were trying to prepare for their old age by themselves. Based on the overall results, the female baby boomers' transferring economic resources to their children implied that they took responsibility for their children. This appears to stem more from to altruistic motivation than reciprocal motivation. Moreover, it can be cautiously concluded that female baby boomers have different perspectives on the transfer of their resources from male's since the interviewees had different opinions on it from their husbands'.

In this paper, we describe the design details and their implementation of a workflow model (or business process model) analysis system to be used for enhancing resource allocation efficiency and operational performance of enterprise workflows. In other word, the analysis works, proposed in this paper, on XPDL-based workflow models aim to verify the static aspects of the workflow models. Also, the system implemented in the paper is able to not only analyze structural patterns and resource allocation plans' efficiency of enterprise workflows modeled by the XPDL process definition language developed by the international standardization organization, WfMC, but also provide various forms of analytical reports. Conclusively, we strongly believe that the workflow analysis system developed in the paper enables workflow modelers to not only analyze and scrutinize structural patterns of their workflow models but also estimate their process resources assigning and planning measurements in order to improve accuracy, reliability and efficiency of enterprise workflows.

내장형 시스템의 개발에 있어서 자원의 효율적인 활용과 정확한 설계를 위해 SystemC를 이용한 통합설계 방식이 많이 사용되고 있다. 하지만 시스템이 점점 복잡해 지면서 단순한 언어차원에서의 개발 뿐 아니라 개발 이전에 시스템의 정확성을 검증해야 할 필요성이 대두되었다. 이를 위해 정형기법 및 테스팅과 같은 방법을 사용하게 되었다. 본 논문에서는 SystemC로부터 정형기법 도구인 VIS의 입력 언어인 BLIF-MV로 자동 변환하는 알고리즘을 제시하고, SystemC 코드로부터의 자동 검증 방법을 제안하고자 한다.

국립기상연구소는 2000년부터 2010년까지(11년)의 위성자료와 수치모델의 재분석 자료를 이용하여 한반도영역에 대해서 $4km{\times}4km$ 해상도의 태양-기상자원지도를 계산하였다. 이러한 태양-기상자원지도를 기반으로 GIS 분석도구를 이용하여 지역별 태양에너지의 분포와 지역별 태양광의 기후특성을 분석하였다. 연구영역의 행정구역을 구분하고 각 지역별 에너지분포 및 변화특성을 쉽게 분석하기 위하여 GIS 분석도구를 사용하였다. 평균 연누적 태양에너지 자료를 분석한 결과 한반도에서는 경상도가 가장 풍부한 태양광에너지를 받고 있었으며 특히 대구광역시(5047MJ), 부산광역시(5019.4MJ)가 높게 나타났다. 북한지역에서는 함경남도(4719.1MJ)가 가장 풍부한 자원을 가지고 있는 것으로 나타났다. 월별 분포를 분석한 결과 대체로 연누적과 동일하게 남부지방의 경상도가 높은 태양광 에너지를 나타났다. 특히 7월 등의 여름철은 1월에 비해 절대적으로 에너지양이 많았다. 그러나 위도 38도를 중심으로 빈번한 장마전선을 동반한 구름의 이동으로 중부지방이 남부지방과 북부지방에 비해 낮게 나타났다. 또한 2000년 1월부터 2010년 12월까지 월별 시계열 변화를 분석해본 결과 한반도 전역에서 태양광의 증가추세가 나타났다. 특히 부산광역시는 10년간 3.75MJ이 증가하였으며, 서울특별시는 3.645MJ/decade, 함경북도는 3.499MJ/decade의 증가경향을 보였다. 월별 시계열 그래프를 보면 2003년 8월과 2005년 4월을 기준으로 3부분에서 다른 특성이 나타나는데 이것은 각 구간별로 구름산출을 위하여 사용된 정지기상위성이 다르기 때문이다. 각 구간에서 사용된 위성은 GMS-5(2003년 8월 이전), GOES-9(2003년 8월~2005년 3월) 그리고 MTSAT-1R(2005년 4월이후)이다. 추후에는 태양광 자원이 풍부한 지역에 대해서 더욱 상세하게 태양광 에너지의 분포와 변화를 분석해보자 한다. 이러한 지역별 자원분석 자료는 지방자치단체들이 신재생에너지 개발계획을 세우는데 도움을 줄 수 있을 것이다.

Construction of multi-site Cloud Infrastructure with OpenStack, the most popular cloud open source project with various ICT infrastructure technologies, has operational inefficiency due to installation complexity and geographical limitation. To address this inefficiency, we gradually developed automated installation/configuration tools to automate installation/configuration of Linux and OpenStack by complying with DevOps methodology over a multi-site OpenStack testbed called OF@KOREN SmartX Playground. However, the pre-developed installation tools can be used only for limited cases. Therefore, we designed and developed a prototype of SmartX Provisioning Framework which could conducts Playground-wide provisioning flexibly by following three steps of resource management in Software-defined Infrastructure. We verified the efficiency of the provisioning functionality of the framework by demonstrating an example of automated multi-site cloud construction.
