Half-Heusler alloys are a potential thermoelectric material for use in high-temperature applications. In an attempt to produce half-Heusler thermoelectric materials with fine microstructures, TiCoSb was synthesized by the mechanical alloying of stoichiometric elemental powder compositions and then consolidated by vacuum hot pressing. The phase transformations during the mechanical alloying and hot consolidation process were investigated using XRD and SEM. A single-phase, half- Heusler allow was successfully produced by the mechanical alloying process, but a minor portion of the second phase of the CoSb formation was observed after the vacuum hot pressing. The thermoelectric properties as a function of the temperature were evaluated for the hot-pressed specimens. The Seebeck coefficients in the test range showed negative values, representing n-type conductivity, and the absolute value was found to be relatively low due to the existence of the second phase. It is shown that the electrical conductivity is relatively high and that the thermal conductivities are compatibly low in MA TiCoSb. The maximum ZT value was found to be relatively low in the test temperature range, possibly due to the lower Seebeck coefficient. The Hall mobility value appeared to be quite low, leading to the lower value of Seebeck coefficient. Thus, it is likely that the single phase produced by mechanical alloying process will show much higher ZT values after an excess Ti addition. It is also believed that further property enhancement can be obtained if appropriate dopants are selectively introduced into this MA TiCoSb System.

This study examined the dyeing characteristics and spectrum of cotton and silk by using dyeing solution extracted from aronia. The value $L^{\ast}$ which indicates the brightness of cotton regardless of mordant increases with increasing pH from pH 3.5 to pH 10.5. The color difference value(${\Delta}E$) of the cotton was generally high in pH 3.5 regardless of mordant existence. The silk showed the highest ${\Delta}E$ value in pH 3.5 dye solution as cotton did. On the other hand, the silk with mordant dyed showed the highest ${\Delta}E$ value in pH 7. Silk fabrics dyed with Aronia solution turns out red in pH 3.5, blue in pH 7 and yellow in pH 10.5. This is because of the amino acid, one of the silk ingredients, combines with a part of anthocyanin to show blue. As the result of the spectrum measurement, the maximum absorption wavelength of Aronia solution was increased in the order of pH 10.5, pH 3.5 and pH 7, regardless of extraction temperature and mordant. The measurement results of color fastness to washing and color fastness to light are generally low. Therefore, there is a need for further study to improve color fatness in the future.

이 소론은 인성과 가치관의 상호연관성을 해명하는 것을 목적으로 한다. 일반적으로 인성과 인격은 서로 다른 개념으로 사용된다. 그러나 이글에서는 양자가 밀접한 관계에 있음을 밝힐 것이다. 인격 없는 인성은 무의미하고 인성 없는 인격은 성립할 수 없다. 인성은 인격의 성립지반이고 인격은 인성이라는 보편적 토대 위에서 성립하는 개별적인 것이다. 인격은 한 인간이 추구하는 가치의 종합이다. 모든 인간은 가치를 추구한다. 따라서 모든 인간은 인격일 수밖에 없다. 그러나 인격은 그 자체 공통적인 것이 아니라 어디까지나 개별적인 것이다. 정신철학적으로 인격은 곧 개인적 정신이 된다. 그러므로 인격과 무인격으로 구별될 수 있는 것이 아니라 높은 인격과 낮은 인격으로만 구분될 수 있다. 그리고 도덕의 성립근거는 인성에 있는 것이 아니라 인격에 있다. 그가 어떤 가치를 추구하는 가에 따라서 도덕적일 수도 있고 비도덕적일 수도 있기 때문이다. 인성이라는 지반 위에서 인격이 성립하고 하나의 개별적 인간이 추구하는 가치의 종합이 인격이라면, 인성은 곧 가치관을 담는 그릇이 된다. 인성과 가치관은 상호간에 영향을 주고받으면서 변화한다. 양자 모두 당시대의 영향을 받는 시대의 아들이다. 인성과 가치관의 담지자인 인간은 자연적 존재이면서 도덕적 존재이기 때문이다.

Woven wire wick is a very effective structure because of its easiness to insert inside of pipe for a miniature heat pipe. The present study was conducted to predict the porosity and the effective thermal conductivity of liquid-saturated woven wire wick. The porosity and the effective thermal conductivity of the evaporator region indicate different values from those of the condenser region due to the existence of non-flow region. The minimum value of the effective thermal conductivity indicates on condition of the $\theta$=$45^{Wcirc}$ and the values of the effective thermal conductivity increases symmetrically centering around the minimum value. The values of the effective thermal conductivity in the evaporator region at the angle of $45^{Wcirc}$ indicate about 60~80% higher than those in the condenser region for various combinations of copper, and stainless with water and ethanol.

All vague and constructions of contemporary cultural environment have been reorganized and the relationship between people and culture can't follow development speed of rapid material civilization development and being informationalized. Because of the circumstances, physical environment is changing into other cultural environment, existence of human being is at a crisis. Physical value precedes mental value and rapid changing causes culture lag. Modernism design of 20th century suggested standard, simplicity and mass production methods, but nowaday, as human being complexity is increasing, information-media are needed to satisfy that. Namely usual design thoughts have to be changed because our life is surrounded by many kinds of powerful media sings and various mixed cultural circumstances. People predict that the characteristics of new ages are 'Immateriality', 'Sensoriality', 'multimedia'. Amongst them, medial spatial characteristics will be eventually remarkable in commercial space which is coincided with economic logic and multilateral culture. This study is a focus on commercial space which emphasis contemporary medial characteristics and observes medial meaning and various technique through some experimental works in Korea. Also this study's purpose is to examine design directions which correspond with contemporary Korea culture.

In an early paper Skumanich suggested the existence of a scaling law relating the mean sunspot magnetic field with the square-root of the photospheric pressure. This was derived from an analysis of a variety of theoretical spot models including those by Yun (1968). These were based on the Schliiter-Temesvary (S- T) similarity assumption. To answer criticisms that such modeling may have unphysical (non-axial maxima) solutions, the S-T model was revisited, Moon et al. (1998), with an improved vector potential function. We consider here the consequences of this work for the scaling relation. We show that by dimensionalizing the lateral force balance equation for the S- T model one finds that a single parameter enters as a characteristic value of the solution. This parameter yields Skumanich's scaling directly. Using an observed universal flux-radius relation for dark solar magnetic features (spots and pores) for comparison, we find good to fair agreement with Yun's characteristic value, however the Moon et al. values deviate significantly.

For the boundary value problem (BVP) of second order functional differential equations for the one-dimensional $\rho$-Laplaclan: ($\Phi$$_{\rho}$(y'))'(t)+m(t)f(t, $y^{t}$ )=0 for t$\in$[0,1], y(t)=η(t) for t$\in$[-$\sigma$,0], y'(t)=ξ(t) for t$\in$[1,d], suitable conditions are imposed on f(t, $y^{t}$ ) which yield the existence of at least two positive solutions. Our result generalizes the main result of Avery, Chyan and Henderson.
