새로운 계산 모델의 도입과 프로세서 속도의 향상에도 불구하고 기억장치 시스템은 여전히 컴퓨터 시스템의 성능 향상을 제한하는 요인으로 작용해 왔다. 특히 공유되는 전역 자료가 존재하는 경우 기억장치 시스템은 병렬 계산의 성능을 크게 저하시킬 수 있다. 따라서 병렬 컴퓨터 시스템에서 공유 자료 구조에 대한 접근의 지역성 및 효율성은 성능 향상을 위해 매우 중요하다. 본 논문에서는 함수 언어의 제약을 극복하고자 제안된 비정형적 자료 구조인 I-구조에 대한 접근을 효율적으로 하기 위한 자료 모델을 제시한다. 전역 기억장소의 비정형적 자료 구조로부터 한 번에 몇 개의 값을 읽어오는 묶음 읽기 기법을 제안하고, 묶음 읽기를 위한 두 가지 루프 그래프 분할 기법을 고안하였다. 그리고, 묶음 읽기의 효율적인 구현을 위해 비정형적 자료 구조의 새로운 태그 관리 기법을 제시한다. Even with new computational models and improvements in processor speeds, the memory system is still a stumbling block to achieve comparable performance of parallel computer systems. Especially sharing global data in parallel computing may cause a considerable performance degradation. Therefore, efficient handling of shared data structures has been a critical issue in enhancing performance of parallel computer systems. In this paper, we propose a data model for efficient access to I-structures, which are non-strict data structures proposed for alleviating limitations of functional languages. We provide a mechanism to read several elements of an I-structure in a bundle from the global memory into the local memory of each processing unit, and design two different partitioning schemes of loop graphs for data bundling. Also, we devise a new tagging scheme for efficient implementation of this bundling mechanism.

Purpose: The purpose of this qualitative study was to explore the experience of becoming a mother after childbirth of Chinese immigrant women in Korea. Methods: Ten Chinese immigrant women were recruited from multi-cultural center in the metropolitan area. Qualitative data were collected through in-depth interview from July 2015 to May in 2016. Interview was conducted until the data were theoretically saturated. Data analysis was performed simultaneously with the data collection, and the contents of the interview were analyzed according to the Corbin and Strauss' grounded theory method. Results: In total, 36 concepts were produced through the analysis, and similar concepts were combined to derive 16 categories. Based on the relation between the categories, the core category is analysed as ‘becoming culture integrating mothers’. The attainment process from this procedural approach are described as cultural intimidated stage, cultural conflicting stage, cultural cooperating stage, cultural integrating stage. There are three types of ‘becoming cultural integrating mothers’, integrating type, conflicting type, and intimidated type. Conclusion: Based on these results, it is suggested to develop the nursing intervention program including cultural sensitive education and consultation program for helping becoming a mother in each type of the Chinese immigrant women in Korea. In addition, nurse or nursing student education program to enhance the cultural sensitivity is also needed.

노은하(Eun Ha Roh),송주은(Ju Eun Song),김문선(Moon Sun Kim) 한국교류분석상담학회 2019 교류분석상담연구 Vol.9 No.1

본 연구의 목적은 영유아 자녀를 둔 맞벌이 부모의 양육경험을 내러티브 질적 연구 분석방법을 통해 탐색하여, 그 경험의 의미를 기초로 저출산 극복을 위한 맞벌이 부모됨 적응증진 프로그램을 개발하고자 수행되었다. 본 연구를 위한 자료수집은 2018년 7월부터 12월까지 서울 및 경기 지역에 거주하는 6세 이하의 자녀를 둔 맞벌이 부모 7쌍의 인터뷰를 통하여 진행하였다. 맞벌이 부모의 양육경험의 의미는, 1) 상호보완적인 의사소통으로 결속력 있는 부모로 성장 중, 2) 조부모 의존적인 양육으로 부모는 경제적인 역할에 치우쳐감, 3) 부부 대화 능력 및 시간 부족으로 가정불화가 커지고 자녀들의 건강한 성장을 위협함, 4) 부모로 준비되지 못해 전문적인 부모교육을 필요로 함 등으로 분석되었다. 따라서 향후 맞벌이 부모의 성공적인 부모됨과 긍정적인 양육경험을 도모하기 위해서는 전문가에 의한 부모교육을 제공할 필요가 있으며, 특별히 자녀돌봄에 대한 지식과 정보를 통합적으로 제공하는 교육뿐 아니라 부부간의 의사소통증진을 도모하는 부모됨 적응증진 프로그램이 필요하다고 본다. The purpose of this study was to investigate the early-parenting experiences of dual-income parents of infants and toddlers through narrative qualitative research method. Based on the meaning of experience, it was carried out to develop dual-income parental adaptation program to cope with low birthrate in Korea. In-depth interviews were conducted in Seoul and Gyeonggi Province from July to December 2018 from 7 pairs of dual-income parents of children aged 6 years or under. The Followings are the meaning of early-parenting experience of dual-income parents, 1) Dual-income parents grow to cohesive parents through complementary communication, 2) Grandparent-dependent parenting causes parents inclined toward providing economic support primarily, 3) The lack of talks and time between husband and wife exacerbates family disagreement and threatens the healthy growth of children, 4) They require professional parent education and resources because they have become aware of their lack of preparedness as parents. Therefore, it is necessary to provide parental education by experts in order to achieve successful parenting of dual-income parents and positive early-parenting experience in the future. In addition to education that provides integrated knowledge and information about child care, the parental adaptation promotion program to promote productive and mature communication between husband and wife is needed in the future.

본 연구의 목적은 맞벌이 부모를 위한 맞춤형 부모적응 증진 프로그램을 개발하고, 이의 효과를 규명하는 것이다. 연구 설계는 비동등성 대조군 전후 시차 설계를 활용한 유사실험연구로, 36개월 ~ 72개월 이하 학령전기 자녀를 둔 맞벌이 부모 중 서울과 경기지역에서 대상자를 편의 표집하였다. 대조군의 연구대상자는 2019년 6월 이후 연구대상자 선정기준에 부합하는 맞벌이 부부 20쌍, 총 40명이 될 때까지 모집하고 3차례 설문조사를 진행하였다. 이후 실험군의 대상자는 2019년 8월부터 선착순 20쌍(40명)의 부모를 모집하여, 맞춤형 부모적응증진 교육을 제공하고 교육 2주후(2차 조사), 4주후(3차 조사) 반복측정 하였다. 연구 분석결과, 맞벌이 부모의 적응증진프로그램 제공여부에 따른 실험군과 대조군 간의 부모양육효능감의 변화양상에 차이가 있었다. 본 연구결과를 바탕으로 맞벌이 부모를 위한 교류분석 이론의 정서적 중재를 강화한 효능증진 프로그램 개발이 필요하다고 본다. The purpose of this study is to develop a customized parental adaptation promotion program for working parents and to investigate its effects. The study design is nonequivalent control-group pretest-post-test design quasi-experimental research. Among dual-income parents with children betweeen 36 and 72 months old, who met the selection and exclusion criteria in Seoul and Gyeonggi Province were sampled for convenience. The study subjects of the control group were recruited from 3 data collection institutions to 20 pairs(40 people) since June 2019, and conducted 3 surveys. After that, the experimental group was recruited from August 2019 to the experimental group. Off-line and online customized parent adaptation promotion education was provided, and repeated measurements were made after 2 weeks (2nd survey) and 4 weeks (3rd survey) after training. As a result of the study analysis, parenting efficacy was analyzed by ANOVA, and parenting efficacy according to the timing of education (F=8.032, p=.001) showed a significant difference in experimental group. The other variables were not statistically significant. The results of this study suggest that it is necessary to develop an enhancement program that strengthens the emotional intervention based on Transactional Analysis Theory in terms of educational content.

Purpose: This study was to explore the postnatal care experiences among first time Chinese immigrant mothers living in Korea. Methods: Data were collected by focus group interviews with 12 first time Chinese immigrant mothers utilizing 3 focus groups. After obtaining written informed consent from all participants, each session of the focus group was audio-recorded and transcribed verbatim. Data were analyzed by content analysis to identify major themes. Results: Four major themes for postnatal care experiences were extracted from the data as follows. 1) Range over traditional, modern, Korean or Chinese postnatal care, 2) Struggle with newborn care, 3) Another struggle with breastfeeding, and 4) Difficulties in becoming a mother as an immigrant. Conclusion: Based on their postpartum care experiences, it is concluded that participants requested more professional practical and individualized education/training for successful breastfeeding and newborn care. Health care providers need to develop and implement integrated support and mentoring programs that include information and peer support system for the first time Chinese immigrant mothers living in Korea. This would decrease the difficulties of becoming a mother.

Purpose: This study aimed to describe knowledge status of current research related to maternal adaptation of women immigrants by marriage in Korea. Methods: Eighteen quantitative current researches published from January, 2006 to August, 2014 that met the inclusion and exclusion criteria. These 18 articles finally selected for systemic review from 5,168 articles. All current researches included the mother within one year after childbirth and one variable related to maternal adaptation at least. Results: Variables related to psychological adaptation (48.1%) were mostly studied. In detail, parenting stress (17.3%) and parenting competency (15.4%) were frequently surveyed. Also, social support (7.7%), husband rearing support (5.8%) of relational adaptation, and acculturation (3.8%) of cultural adaptation were importantly studied. In addition, frequently used instruments for each study variable were analyzed and evaluated. As major results, parenting stress and parenting efficacy were significantly influenced by social support or husband rearing support and acculturation, and had an effect on parenting behaviors. Various maternal education programs were effective in improving maternal role confidence or parenting efficacy and decreasing parenting stress. Conclusion: Nursing intervention programs for improving maternal adaptation should focus on decreasing parenting stress and increasing parenting efficacy by improving social support and acculturation level of women immigrants by marriage in Korea.

DAVRID 다중스레드 구조에서 비정형적 자료 구조에 대한 자료 병렬성의 극대화

김흥환,노은하 서원대학교 응용과학연구소 1995 응용과학연구 Vol.4 No.1

Even with introduction of new computational models and improvements in processor speeds, the memory system is still a stumbling block to achieve comparable performance of computer systems. Especially the existence of shared global data may cause a considerable performance degradation in parallel computing. Therefore, it is very important to exploit data locality by distributing data structure and scheduling computations according to the distributed data. In this paper, we present a data parallelism scheme in nonstrict data structures for a multithreaded architecture DAVRID. We suggest a data parallel programming language, DAPID(DAta Parallel ID), which is an extension of parallel programming language Id. In a bundle. For the efficient implementation of this mechanism, we also suggest a new structure and a new scheme of tag manipulation in nonstrict data structures.

대학 IT 교과과정의 요구분석과 점진적 개발

박수희,노은하 同德女子大學校 情報科學硏究所 2005 정보과학연구 Vol.9 No.-

산업체 수요지향적인 대학 IT 교과과정 개발 방법론에서는 여러 반복단계를 거치면서 완성도 높은 교과과정을 산출한다. 하나의 반복단계는 준비, 요구분석, 설계, 구현, 실현, 평가 등의 과정으로 나뉘는데, 이 중 요구분석 과정은 새로운 반복단계에서 양질의 산출물을 얻기 위한 주요 과정이다. 본 논문에서는 이전 반복단계의 수행 결과를 바탕으로 이해관계자로부터 요구사항을 수집하고 분석하여 새로운 반복단계를 준비하여 IT 교과과정을 점진적으로 개발하는 과정을 다룬다. 이러한 점진적 개발 프로세스는 지속적으로 발전하는 IT 분야의 특성상 끊임없이 반복되어야 한다. In the methodology of industrial demand-driven college IT curriculum development, the in-depth curriculum development is done throughout many iterations. A single iteration is consisted of several phases: preparation, requirement analysis, design, implementation, realization, and evaluation. Among them, the requirement analysis is an important phase to produce artifacts of good quality. In this paper, based on the artifacts of the previous iteration, stakeholders' requirements are collected and analyzed. A new iteration is started and IT curriculums are incrementally developed. This incremental process needs to be repeated in order to catch up continuous growth of the IT industry.
