There are two standards for evaluation of fabric aesthetics, the feeling of fabric and the fabric sense of sight. Its drapalility with lustre is one of factors to decide the fabric sense of sight. This study was carried out to investigate the drape property property of fabrics. The fabric characteristics and the physisical properties of fabrics were tested. And the effect of the laundering on the drape properties was examined. RESULTS : 1. The drape coefficients of sampled fabrics were increasd as the thickness of fabrics were increased, excluding the fabric consisting of 60% polyester$\times$40% wool. 2. The drape coefficient of sampled fabrics were decreased as the cover faders of fabrics were increased, excluding the summer clothes and the fabrics of 100% wool. 3. The drape coefficients of fabrics other than sumer clothes were increased as the weight of fabrics were in creased. 4. Positive correlation was observed between the stiffness and the drape coefficient. 5. Negative correlation was observed between the fabric shrinkage and the drape coefficient. 6. The drape coefficient was decreased to a certain limit by laundering.But as the laundering was repeated up to certain number, the drape coefficient and the node number, a significant correlation was observed between the drape coefficient and the node shape.

본 연구에서는 고유함수 전개법을 이용하여 다양한 형태의 함몰지형 위를 통과하는 파랑의 반사율을 계산하였다. 기울기와 곡률이 변하는 지역에 고유함수 전개법을 적용하여 해석 시 필요한 적절한 구간의 수와 소멸파 성분의 개수를 제안하였다. 천해역 및 중간수심영역을 만족하는 조건에서 다양한 형태의 함몰지형에 대해 반사율을 계산하여 최적의 효율을 가지는 단면의 형상을 제시하였으며 최적 단면을 2열 및 3열로 배열하여 배열 간격에 따른 반사율을 계산하였다.

The fluctuating wind pressure of the low rise ratio(f/D=0.1) for the elliptical dome roof was analyzed to compare it with the previous studies of circular dome roofs. Wind tunnel test were conducted on a total of 10 wind directions from 0° to 90° while changing wall height-span ratios(H/D=0.1-0.5). For this, meanCP, rmsCP and wind pressure spectrum were analyzed. The analysis result leads to find differences in the shape of the spectra in the spanwise direction and leeward of the elliptical dome according to the wind direction variations of the elliptical dome roof.

본 연구의 목적은 만성질환자의 건강 관련 의사결정에 대한 자율성 선호도에 영향을 미치는 요인을 확인하기 위함이다. 대상자는 일개 보건소에 등록된 만성질환자 522명이다. 수집된 자료는 SPSS Win 26.0 ver. 프로그램을 이용하여 기술통계, t-test, ANOVA, Scheffe-test, Pearson's correlation coefficients, multiple linear regression으로 분석하였다. 연구결과, 만성질환자의 일반적 의사결정 선호도의 영향요인은 건강에 대한 관심정도(β=-.17, p<.001)이었으며. 정보추구 선호도의 영향요인은 성별(β=-.20, p<.001)과 진료 시 질문하는 횟수(β=.09, p=.030)이었다. 본 연구는 만성질환자들이 본인의 치료 과정에서 주도적으로 역할을 할 수 있도록 환자의 특성을 고려해야 하며, 환자의 주도적이고 효율적인 의사결정을 돕기 위하여 의료인의 효과적인 의사소통 전략 수립이 필요함을 시사한다.

FACES II & III do not capture the high extremes of the dimension and are linear rather than curvilinear measure. FACES IV is the latest revision of FACES series and can capture two extreme dimension of Circumplex Model. The purpose of this study is to examine reliability and validity of reconstructed FACES using by FACES II, III, IV. Factor analysis showed that Cohesion and Adaptability consisted 3 factors (disengaged, connected, emmeshed/rigid, flexble, chaotic) Extremes on each dimension conceptually were opposite and they were uncorrelated with each other. FACES effectively predicted family function. Reliability coefficients of subscales ranged from 61~85 Reconstructed FACES had good internal consistency and construct and criterion related validity.

This paper was studied changes of physical properties of Lining fabrics by washing and difference between dry method. I experimented four kinds of Lining fabrics for the sample . The analysis was performed by correlation coefficient analysis and significance tested between correlation coefficients. The results are summarized as follows : 1) Increasing rate of shrinkage tends to call high density and weight. 2) Rayon fabrics is shown the most high rate of shrinkage and decreasing strength by increasing washing times. 3) Drip dry makes little change of physical properties. 4) Polyester fabrics is little by washing times and dry method.

본 연구는 유역 추적에 자주 쓰이는 합성단위 유량도(synthetic unit hydrograph) 방법의 하나인 Snyder 방법에 있어서의 계수를 남한강수계에서 재조정하는 과정(procedure)을 제시하였다. 그 과정을 간략하게 설명하며, 이전에 구한 남한강 수계에서의 snyder 계수를 초기치로 하여 HEC-1 program을 이용하여 계수를 재조정한다. 이와 같은 과정을 통하여 재조정된 계수는 그 전의 계수에 의한 합성단위 유량도보다 지체시간($$)이 작아지고 첨두(peak)값이 커지는 특성을 가지고 있다.

The purpose of this study was to investigate the relationship between children's attributional style and their self-perceived competence. The subjects of this study were 301 third and sixth grades. For data analysis, two-way ANOVA, Pearson's correlation coefficients, and multiple regression were used. Results indicated that there was significant correlation between children's attributional style and their self-perceived competence. Children who attributed good events to intemal, stable, or global causes and bad events to extemal, unstable, or specific causes perceived themselves more competent.
