The aim of this investigation was to delineate concepts contributing to the Exercise of Self-Care Agency (E.S.C.A.) Scale developed by Kearney & Fleischer (1979) and to test its construct validity and its predictors. The results are summarized as follows ; 1. By means of principal factor analysis and maximal likelihood factor analysis upon data generated from 280 undergraduate students, the factors of Concern about Health Knowledge, self-Concept, Information - Seeking Behavior, Decision -making and Responsibility, Self-esteem, and Passivity emerged. The total percent of variance explained by the 6 factors was 75.1% 2. To assess factor independence and instrument homogeneity, correlations among the 6 factors were computed. The correlations ranged from .24 to .46 indicating that the factors and the items were not too similar or redundant. 3. Test-retest reliability of the total scale is r＝.70. Cronbach's $\alpha$ coefficient for internal consistency of the total scale is .86 and that of the factors ranged from .750 to .661 (only factor 6 .497). 4. In additional analysis of the Exercise of Self-Care Agency Scale in relationship to Multiple Health Locus of Control, Family Environmental Scale, and Cornell Medical Index using stepwise multiple regression, the Internal Health Locus of Control Score predicted 21.8%(F＝53.34, p＝.0001), Family Environmental Score 8.3%(F＝22.59, P＝.0001), Modified Cornell Medical Index Score 5.4%(F＝15.74, P＝.0001) of the score of the E.S.C.A.

$Premi\grave{e}re$ Vision is a leading textile collection held since 1973. In this study, textiles for 2004/05 F/W season in $Premi\grave{e}re$ Vision were analyzed at the various point of view, such as general trend, sub-theme, fiber content, color trend, structure, yarn trend, pattern, texture, decoration, finishing and other technical treatment, and functionality. There were three general trends; natural/ecology, geometry, and combination. Natural color and texture were widely used over the fabric exhibited, and irregularities expressed the natural trend of textiles. Geometric patterns were used for knit as well as for woven. Geometry expressed by various methods such as weaving, knitting, printing, shearing, embossing, and etc. However, geometry shown in this season was not a clear form expressed by weaving, but a blurry, irregular form expressed by various other methods such as knitting. The combination among heterogeneous fibers, yarns, colors, images, and textures was usual, however, the harmony among them was accomplished.

본 논문에서는 4.4GHz 대역에서 항공기내 무선 통신을 위한 채널 링크 버짓을 분석하였다. 항공기내의 채널을 일반적인 경로 손실, 장애물로 인한 음영효과, 그리고 다중 경로 신호로 인한 페이딩의 조합으로 모델링하였다. 그리고, 항공기내에 존재할 수 있는 송수신기의 다양한 위치에 따라서 채널을 A~F의 6개 그룹으로 분류하고, 6개의 채널 그룹별로 최대 전송 가능 거리와 전송 오류 확률 측면에서 링크 버짓을 분석하였다. 다양한 분석과 컴퓨터 시뮬레이션 결과에 따르면, A, B, F 채널 그룹이 C, D, E 그룹 대비 우수한 전파 특성을 가지며, 그룹 E의 전파 특성이 가장 열악한 것으로 확인되었다. 이러한 결과들은 항공기내 또는 이와 유사한 환경에서의 채널 분석을 위한 기초자료로 활용 가능하다.

We report the crystallographic and magnetic properties of $Ni_{0.3}Fe_{0.7}Ga_2S_4$ by means of X-ray diffractometer (XRD), a superconducting quantum interference device (SQUID) magnetometer, and a M$\ddot{o}$ssbauer spectroscopy. In particular, $Ni_{0.3}Fe_{0.7}Ga_2S_4$ was studied by M$\ddot{o}$ssbauer analysis for evidence of spin reorientation. The chalcogenide material $Ni_{0.3}Fe_{0.7}Ga_2S_4$ was fabricated by a direct reaction method. XRD analysis confirmed that $Ni_{0.3}Fe_{0.7}Ga_2S_4$ has a 2-dimension (2-D) triangular lattice structure, with space group P-3m1. The M$\ddot{o}$ssbauer spectra of $Ni_{0.3}Fe_{0.7}Ga_2S_4$ at spectra at various temperatures from 4.2 to 300 K showed that the spectrum at 4.2 K has a severely distorted 8-line shape, as spin liquid. Electric quadrupole splitting, $E_Q$ has anomalous two-points of temperature dependence of $E_Q$ curve as freezing temperature, $T_f=11K$, and N$\acute{e}$el temperature, $T_N=26K$. This suggests that there appears to be a slowly-fluctuating "spin gel" state between $T_f$ and $T_N$, caused by non-paramagnetic spin state below $T_N$. This comes from charge re-distribution due to spin-orientation above $T_f$, and $T_N$, due to the changing $E_Q$ at various temperatures. Isomer shift value ($0.7mm/s{\leq}{\delta}{\leq}0.9mm/s$) shows that the charge states are ferrous ($Fe^{2+}$), for all temperature range. The Debye temperature for the octahedral site was found to be ${\Theta}_D=260K$.

This study pursued to find out the degree to which educational objectives are pursued in the 3rd and 5th grade science instructional of an elementary school. Twenty science instruional hours are observed during two month from May to July, 1989. Klopfer's science educational objectives system is used as the tool of objective analysis. Questionnaires for the ideal proportions of the educational objectives are answered by the professors and elementary school teachers. The writers regarded those results as the ideal proportions of the educational objectives. Results from the analysis of the instruction are as follows : 1. Results from analysis of the instruction in the third grade are as follows : knowledge and comprehension (A. 0) objectives are found to be pursued. about 40%. scientific inquiry process(B. 0-E. 0) objectives, about 29%, application of scientific knowledge and methods(F. 0) objectives. about 10%, manual skills(G. 0) objectives, about 11%, scientific attitudes and interests(H. 0) objectives, about 10% and orientation(I. 0) objectives is not pursued. 2. Results from analysis of the instruction in the fifth grade are as follows: knowledge and comprehension(A. 0) objectives are found to be pursued. about 31%, scientific inquiry process (B. 0-E. 0) objectives. about 38%, application of scientific knowledge and methods (F. 0) objectives, about 13%, manual skills(G. 0) objectives, about 7%, scientific attitudes and interests(H. 0) objectives, about 10%. 3. Results from the ideal proportions are as follows : Knowledge and comprehension(A. 0) objectives, 20.5%, scientific inquiry process(B. 0-E. 0) objectives, 46.5%, application of scientific knowledge and methods(F. 0) objectives. 8%, manual skills(G. 0) objectives. 9.5%, scientific attitudes and interests (H. 0) objectives, 9% and orientation(I. 0) objectives, 6.5%. 4. "You ideality index" is 29 in the third grade and 23 in the fifth grade.

For any given function f, we focus on the so-called prescribed mean curvature problem for the measure e^-f(|x|2)dx provided thate^-f(|x|2) ∈ L¹(ℝⁿ⁺¹). More precisely, we prove that there exists a smooth hypersurface M whose metric is ds² = dρ² + ρ²d𝜉² and whose mean curvature function is ${\frac{1}{n}}(\frac{u^p}{{\rho}^{\beta}})e^{f({\rho}^2)}{\psi}(\xi)$ for any given real constants p, β and functions f and ψ where u and ρ are the support function and radial function of M, respectively. Equivalently, we get the existence of a smooth solution to the following quasilinear equation on the unit sphere 𝕊ⁿ, $${\sum_{i,j}}({{\delta}_{ij}-{\frac{{\rho}_i{\rho}_j}{{\rho}^2+|{\nabla}{\rho}|^2}})(-{\rho}ji+{\frac{2}{{\rho}}}{\rho}j{\rho}i+{\rho}{\delta}_{ji})={\psi}{\frac{{\rho}^{2p+2-n-{\beta}}e^{f({\rho}^2)}}{({\rho}^2+|{\nabla}{\rho}|^2)^{\frac{p}{2}}}}$$ under some conditions. Our proof is based on the powerful method of continuity. In particular, if we take $f(t)={\frac{t}{2}}$, this may be prescribed mean curvature problem in Gauss measure space and it can be seen as an embedded result in Gauss measure space which will be needed in our forthcoming papers on the differential geometric analysis in Gauss measure space, such as Gauss-Bonnet-Chern theorem and its application on positive mass theorem and the Steiner-Weyl type formula, the Plateau problem and so on.

To analyze th frequency modulation system the characteristic equation of the F-M system, i.e., Mathieu's equation, is derived from the equivalent circuits of direct modulation system. The analysis of F-M equation is undertaken by the Yonsei 101 Analog Computer. And the computer solution is compared with the theoretical solution. It is concluded that not only the frequency but also the amplitude of the carrier wave are changed by varying the modulation index and the system becomes unstable if the modulation index is increased near to unity.
