  • The purpose of this study was to highlight the importance of 'marital preparation skill' by focusing on more substantial and tangible skills in marriage life, and to conduct an exploratory research to examine the current conditions and gender differences in marital preparation skills of college students. Data were gathered through a self-administered questionnaire in four universities located in Seoul and Gyeong-gi areas in the spring of 2013, and a total of 332 senior students chosen were used for data analysis. Based on the instrument used in Olson & Olson's(2000) PREPARE/ENRICH Program, the present study sought to suggest a measurement tool with the moniker of 'marital preparation skill' that included seven domains: conflict resolution skill, sexual relationship skill, household labor skill, financial management skill, leisure management skill, parenting preparation skill, and parental role skill. Each domain consisted of four items and thus, a total of 28 items were utilized for this study. Descriptive statistics were analyzed in order to examine the degree of marital preparation skills, and t-tests were conducted in order to assess the gender differences in marital preparation skills. The main results of this study are as follows: First, overall the degree of marital preparation skills of male students was higher than that of female students. Particularly, female students were lower than male students in the skills of financial management and conflict resolution. Second, regarding the basic household labor skill related to clothing and housing life, male students showed higher than female students, implying the impact of military life. Third, even though the degree of consciousness about appropriate preparation of parenthood and parental role seemed to be heightened, the actual degree of readiness of college students revealed to be insufficient. Male students had a much higher degree of confidence and sacrifice acceptance about parenthood, and understanding about their parents' child-rearing style than female students, while the mindset of child-rearing participation of male students was lower than that of female students. Findings of this study can be used as basic data for developing more effective and differentiated educational programs of marital preparation skills for men and women.

  • This study presents the tests of an Immersed Membrane BioReactor (IMBR) equipped with a draft tube and focuses on the influence of hydrodynamic conditions on membrane fouling in a pilot-scale using a hollow fiber membrane module of ZW-10 under ambient conditions. In this system, the cross-flow velocities across the membrane surface were induced by a cylindrical draft-tube. The relationship between cross-flow velocity and aeration strength and the influence of the cross-flow on fouling rate (under various hydrodynamic conditions) were investigated using Multi-Dimension Scaling (MDS) analysis. MDS technique is especially suitable for samples with many variables and has relatively few observations, as the data about Membrane Bio-Reactor (MBR) often is. Observations and variables are analyzed simultaneously. According to the results, a specialized form of MDS, CoPlot enables presentation of the results in a two dimensional space and when plotting variables ratio (output/input) rather than original data the efficient units can be visualized clearly. The results indicate that: (i) aeration plays an important role in IMBR performance; (ii) implementing the MDS approach with reference to the variables ratio is consequently useful to characterize performance changes for data classification.

  • 본 연구의 목적은 Antonak(1982)이 개발한 SADP and ATDP-O(Scale of Attitudes for Disabled Persons and Attitudes towards Disabled Persons Scale-Original)척도의 타당도를 검증하고 국내에서의 활용방안을 모색하는 것이다. 이를 위해 공무원, 의료인, 교사, 언론인, 장애인복지시설 종사자로 구성된 표적집단과 일반집단으로 구분한 비장애인 500명을 표집하여 척도의 타당도 및 신뢰도를 검증하고, 표적집단과 일반집단 간의 장애인에 대한 태도 차이를 비교하였다. 탐색적 요인분석 결과, 원 척도는 '염세주의-고정관념', '낙관주의-인권', '손상된 성격' 세 가지 차원의 15개 문항으로 정리되었고, 확인적 요인분석 결과, 재구성한 척도의 적합성은 수용할만한 수준(good/reasonable fit)인 것으로 나타났다. 전체척도의 Cronbach's ${\alpha}$ 값은 .8이 넘어 안정적인 신뢰도를 보였으며, DFS(Disability Factor Scale)와는 전반적으로 높은 수준에서 통계적으로 유의미한 상관관계를 나타내 수렴타당도가 확보되었다. 또한 표적집단이 일반집단보다 장애인에 대해 긍정적인 태도를 지닌 것으로 나타났다. 본 연구에서 타당도가 검증된 도구는 다양한 장애유형에 활용할 수 있도록 장애유형별 검증이 필요하며, 척도의 활용으로 장애인에 대한 태도를 개선하기 위한 임상적, 실천적 방안이 모색되어야 할 것이다.

  • 본 연구는 지역간 소득분포의 수렴/발산의 주요 측면인 베타-수렴을 공간자료분석에 의거하여 비판적으로 검토하고 있다. 베타-수렴에 대한 통상적인 접근법은 두 가지 측면에서 문제점을 갖고 있다. 첫째, 회귀분석 결과 도출되는 잔차의 공간적 자기상관을 고려하지 못한다. 둘째, 베타-수렴의 국지적 변이, 즉 공간적 이질성을 탐색할 어떠한 절차도 제공하지 못한다. 이러한 비판적 검토를 바탕으로, 다양한 공간자료분석 기법들, 즉, 공간적 자기회기 모델(spatial autoregressive models), 이변량 국지통지(bivariate local statistics)를 이용한 탐색적 공간자료분석(ESDA: exploratory spatial data analysis) 기법, 그리고 지리적 가중회귀분석(GWR: geographically weighted regression)을 사용하여 1969-1999년 간의 미국 노동시장지역에 대한 소득 자료를 분석하였다. 주요 결과는 다음과 같다. 첫째, OSL모델을 적용한 결과 베타-수렴은 단지 부분적으로만 드러났고, 베타-수렴 계수도 시기별로 상당한 편차를 보였다. 둘째, 공간적 자기회기 모델의 분석 결과 OLS에 의해 유의한 것으로 나타난 베타-수렴 계수가 99% 신뢰수준에서 유의하지 않은 것으로 드러났다. 셋째, 탐색적 공간자료분석과 지리적 가중회귀분석의 결과는 베타-수렴의 경향에 상당한 정도의 공간적 이질성이 존재한다는 점을 보여주고 있다. 또한 이 공간적 이질성의 양상이 시기별로도 다양하게 드러남이 관찰되었다.
