Electro-osmotic pumps were fabricated by using two types of porous glass frits. The performance of these pumps was characterized in terms of maximum flow rate, current, and pressure using deionized water and 1 mM sodium tertraborate decahydrate buffer. Maximum flow rate and current when ROBU porous glass frits were used were higher than those when DURAN porous glass frits were used because of the high porosity of the ROBU glass frits. However, the maximum pressure when ROBU glass frits were used was similar to that when DURAN glass frits were used. The therrmodynamic efficiency of a pump with ROBU porous glass frits is approximately twice that of a pump with DURAN porous glass frits. Further, the maximum flow rate at maximum current in the case of ROBU porous glass frits is high. However, it is lower than the maximum pressure at maximum current in the case of DURAN porous glass frits. Further, in this study, we also verified the effectiveness of ROBU glass frits when high flow rate is required and of DURAN glass frits when a high pressure is required.

The East has recognized 'similar forms' and 'similar spirits' as important topics in expressing an object. Figure painting, in particular, has attached importance to 'transmission of spirit'. Gu Kaizhi (345-406) definitely presented the transmission concept and made it the moot important criterion in painting criticism. By identifying the possibility of revealing spirit through a form, he recognized the 'expression of will' in a creator's work and the experience of such 'expressed will' by an appreciator to be the essential acts of art. Thus, he said, a figure painting revealed the character and nature of the depicted object rather than reproducing its form. Regarding art as a person creating the saintly way of life via developing own character, he attached importance to the will of an artist as the central aesthetic subject. This dissertation explores the keynote of the spirit expressing an artist's inner world and the external shape of a figure. It is carried out by investigating the process of Gu Kaizhi's theory (namely spirit transmission and revelation in painting) leading to Su Dongpo's assertion that "the nature of things" and later leading to Yun Duseo's "theory of the way of painting" as the spirit-transmission theory faithful to the principle of revealing spirit through a form in Chosun. The chronological study of the aforementioned works reveals that the relation between an artist and an object is important at the stage of setting aim in producing a work, and this dissertation analyzed it with four elements: (1) creating work based on the viewpoint of nature that heaven and man are one; (2) reflection of the creator's character (including his/her nature, temperament, spirituality, and emotion during the creation) and the artistic merit of a picture; (3) the dialectic unification between the true and the false through space which is a volitional state as creative thinking space; (4) importance of artist's will above the technique used such that a purposeless, inactive and plain work (where human will is combined with heavenly one) was pursued because the picture is regarded coming from the mind created in the unity of host/artist and guest/object. Thus, through his/her intuitive insight is the world where self is united with the cosmos symbolized. Such expression of an artist's inner world and the external shape of a thing pursues the stage of materialization and creates the new modes such as using space, a variety of brushstrokes, and accidentality and improvisation of India ink. In particular, the writer sees that such expression which enables a creator to express his/her nature or personality (and even the emotion) at the time of creation will be highly worth studying in the future, in accord with the pursuit of contemporary painting being expressed as an abstract aspect.

The purpose of this study was to evaluate the competence level of the caregiver and verify empirically the evaluated score of the competence level of the caregiver depending on the type of career and employment to propose a measure to improve the quality of care services. To more accurately evaluate the competence level of caregiver, the collected data were analyzed using fuzzy relationships for identifying the extent of relationship, after setting weighted values for the evaluation factors for working levels and service qualities. Such approach has a significance in that individual evaluation factors and individual's competence levels for caregivers may be more suitably and exactly identified. The analysis results are as follows. Care skill, reliability, assurance, typicality were statistically significant according to the caregiver's career. Also, according to the types of employment, job consciousness, responsiveness, empathy, typicality were statistically significant. To improve the competence level of the caregiver, it may be seen that improvement of job consciousness considering the career and employment types and making environments for acquiring the care skills should be done, while providing stability of the employment types rather than careers is more meaningful to improve the quality of services.
