French poststructuralists Gilles Deleuze and Felix Guattari pointed out that the minority age already has come in the modern society through discussing minority topic. Futhermore, they supported 'Becoming' as new methodology that minorities escape from suppressed reality. 'Becoming' is the practical concept for how one identity could split into different lives and subjects, thus it could be explained as an exemplary that autonomous change and actively entering into different lives. The purpose of this study seeks the practical way for elder women can independently participate in media education which is based on concretely 'becoming woman'. For this, the article examines the main concept and thought of Deleuze and Guattari. The reason why this article premises this theory is for changing 'desire' of elder women's approach to 'becoming women' through new interpretation about minority and minorities which were defined by quantitative criteria. Consequently, this article would suggests the direction of senior media education for seniors for the positive and specific effect.

Effects of material surface property, hydrophobic or hydrophilic, on the bio-fouling occurred on the bodies submerged in the sea water are investigated experimentally. 4 test models are used in the experiment, which includes aluminum foil in common use, AAO applied hydrophobic surface, HDFS coated hydrophobic surface and hydrophilic surface. Hydrophobic surfaces with numerous micro & nano-scale pillars on it seems to play very important role of preventing them from fouling in initial stage while the effects disappear in long term sense of fouling process. It is concluded that the surface hydrophobicity retards the initial fouling until the fouling thickness is smaller than the heights of the pillars on it but the effects diminish with the fouling proceeds so that the thickness grows bigger than the pillar heights.

To obtain basic information for characteristics of naked barley cultivars, awn length and weight, kernel weight along spikelet positions of some cultivars bred in Korea were investigated. Awn length and weight of third to fifth spikelet, and kernel weight of second to fourth spikelet from spike tip were not different from each mean value for total of spike. From the spike base, awn of third to fourth spikelet was longest and heaviest, and kernel weight of fifth to sixth spikelet was heaviest. Value for awn length, awn weight, and kernel weight of lateral row florets was lower 13 to 26％, 26 to 41％, and 18 to 25％, respectively than one for those of central row floret. Difference for awn length and weight between central and lateral row in nami type cultivars compared to uzu type cultivars was small. In the ratio of weight/length of awn, awn of uzu type cultivars was thicker than that of nami type cultivars, and awn of central row was thicker than those of lateral rows. Kernel weight was linearly related to awn weight. When one spike was divided into three parts, awn length and weight of low part were not different from those of central part, but were longer and heavier than those of upper part. The order of kernel weight was central$\geq$low>upper part.

This study was conducted to examine the effect of aqueous chlorine dioxide treatment as a washing method on removal of pesticide residues. Three pesticides of chlorpyrifos, diazinon, and metalaxyl, which are commonly used in vegetable crops, were treated with 10, 50, and 100 ppm of aqueous chlorine dioxide and decomposition of the pesticides was determined using gas chromatography. Three pesticides used in this study were decomposed by aqueous chlorine dioxide treatment and removal rate was proportional to treatment time as well as concentration of aqueous chlorine dioxide. In particular, 100 ppm of aqueous chlorine dioxide treatment decreased the pesticides efficiently. In addition, lettuce was treated by dipping in distilled water and 100 ppm aqueous chlorine dioxide, respectively, and was compared regarding removal efficiency of the pesticides. The results revealed that washing with 100 ppm aqueous chlorine dioxide for 10 min was the most effective for removing the pesticides. These results suggest that aqueous chlorine dioxide can be used as a washing method of fresh produce to remove the residual of pesticides.

The purpose of this study was to identify pre-service teachers' Pedagogical Content Knowledge (PCK) about decimal calculation. A written questionnaire was developed dealing with decimal calculation. A total of 152 pre-service teachers from 3 universities were selected for this study; they had taken an elementary mathematics teaching method course and had no teaching experience. The results were as follows: First, with regard to the method of decimal calculation, most pre-service teachers were familiar with algorithms introduced in the textbook. But with regard to the meaning of decimal calculations, they had difficulties in understanding decimal multiplication or decimal division with decimal number. Second, pre-service teachers recognized reasons of errors as well as errors patterns that student might make. But this recognition was limited mainly to errors related to natural number calculation. Third, pre-service teachers frequently commented about decimals algorithms, picture models, the meanings of decimal calculations, and connections to natural number calculations. Many of them represented the meanings of decimal calculations through picture models as to help students' understanding, while they just mentioned algorithms or treated decimal calculation as natural number calculations with decimal point.

This study describes the evaluation results on the effect of soil particle surfaces coated with various hydrophobic conditions on spectral information according to water content. Wettability test and spectral information evaluation test were performed on the hydrophobic coated standard sand. When the standard sand was coated with 1%, 3%, and 5% hydrophobic, the contact angles of sand-water interface were 130°~143°, 129°~144°, and 131°~144°, respectively. This means that the contact angle increased as the degree of hydrophobic coating increased at the same drying time, but the range of the contact angle had the same wettability. This means that the contact angle increases as the hydrophobic coating degree increases at the same drying time, whereas the contact angle range has the same wettability. As a result of spectral information evaluation, the maximum spectral reflectance of the dried sand with hydrophobic condition decreased compared to that of the hydrophilic sand, as the degree of hydrophobic increased. However, the maximum spectral reflectance was increased by increasing the degree of hydrophobic under the same water content conditions.

The aim of this study is to explore the relationships among paranoid tendencies, cognitive characteristics and prejudice. Revised Minnesota Multiphasic Personality Inventory Pa scale, Harris-Lingoes Naivetes(Pa3), dichotomous thinking(DT), attributional style, prejudice toward minority groups(migrant workers, homosexuals, and homeless people) were administered to 557 college students. High Pa3 group was significantly low in prejudice toward minority groups. Also, the group with higher DT showed more prejudice toward minorities. The suggestions and the limitations of this study, and the directions of future study were discussed.

This research investigated the influence of subjective well-being on attitude towards minority group members. In a cross-sectional data, the higher subjective well-being predicted more positive cognitive beliefs, affective feelings, and behavioral intentions towards foreign laborers and children of international couples. The causal link from subjective well-being to greater tolerance for cultural diversity was found again in a large longitudinal sample. The rate of life satisfaction increase from Time 1 to Time 2 significantly predicted multicultural receptiveness at Time 2. Overall, the findings suggest that subjective well-being may contribute to the formation of favorable attitude towards minority group members.

The hydrophobicity of the microbial cell surface is responsible for the various interactions between microorganisms and different surface, and results in the flocculation of microbial cells, their adhesion to liquid or solid materials, and the floatation of microorganisms at the air-water interface. Accordingly, cell surface hydrophobicity is important not only in medicine but in other areas of biotechnology. This article reviews the role of cell surface hydrophobicity and its applications.
