        환경친화형 수분산성 불소 아크릴레이트 공중합체에 의한 섬유 표면개질

        유수용,김정두,문명준,서차수,주창식,이민규 한국환경과학회 2004 한국환경과학회지 Vol.13 No.10

        Waterborne fluorinated acrylate copolymer (WFAC) for surface modification of textile was synthesized from perfluoroalkyl ethyl acrylate, octadecyl acrylate, glycidyl methacrylate, surfactant and 3,3 methyl-methoxy butanol. The structures of the synthesized WFAC were determinated by FT-IR and ^(19)F-NMR analysis. The thermal stability investigated with DSC and TGA was decreased with increasing the content of fluorinated acrylate in the copolymer. However, the particle sizes of WFAC were increased with increasing the content of fluorinated acrylate in the copolymer. The surface energies calculated by contact angles of WFAC were in the range of 29.80~3.41 dyne/cm. On the observing SEM of the textile surface treated with WFAC, the textile was swollen and compacted with increasing the concentration of water repellency agent. WFAC synthesized in this study showed a good water repellency.

        ■ Objectives The purpose of this study was to estimate qualitatively various bulk deposition flux of insoluble heavy metal components by applying regional and seasonal distribution. our institution from January 1980 to December 31th, 2001. ■ Materials and Methods Dustfall particles were collected by the modified American dust jar (wide inlet bottle type) at 6 sampling sites in Pusan area from March, 1999 to February, 2000. Five chemical species (Cd, Cr, Mn, Ni and Pb) were analyzed by AAS(Perkin-Elmer 4100ZL). ■ Results The mean values of each heavy metal concentrations were Cd for 3.947 g/㎢/month, Cr for 0.191 ㎏/㎢/month, Mn for 0.375 ㎏/㎢/month, Ni for 0.176 ㎏/㎢/month, and Pb for 0.823 ㎏/㎢/month. ■ Conclusions Insoluble heavy metal amount of regional variations were found in order of industrial zone, coastal zone, commercial zone, agricultural zone and residential zone.

      • 大學 新入生의 道德的 事態判斷 水準 및 槪念化 樣相의 分析

        This study was conducted in order to analyze freshmen's level of cognitive judgment of moral situations and their conceptions of moral situation in different conceptual domains. The research questions to be answered in this study were as follows : 1) What are freshmen's levels of the judgment in moral situations, and are the levels differentiated according to their sex and majors? 2) What are the justifications in each domain? In other words, how do justifications of nonpermissibility, generality, and rule-independency differ in such domains as moral, conventional, and personal? 3) How are freshmen's conceptions of moral situation characterized? Subjects in this study were 200 freshmen(131 boys and 79 girls) randomly sampled from Dong-a University. The instruments were Kim's(1985) Test of Moral Development Judgment which was translated from Rest's(1979) DIT, and 9 interview situations for moral judgment and justfication developed by the current researchers on the basis of Turiel's theory. Subjeects were presented with six moral dilemas and 9 moral situations by 10 research aides who are seniors of education department of dong-A University, specially trained for this study. Data were analyzed statistically to answer the research questions. The major findings of this study were as follows: 1) More freshmen attained level P in terms of judgment of moral situations, while some other students did levels three and four. Therfore, it is considered that a large amount of freshmen start the principled-stage thinking. 2) Many freshmen showed high degree of transitional phase(4½) as level P according to frequencies in each moral stage. This reflects the apparent regression from the hightest stages to stage 2 during freshmen's campus life. Additionally, this kind of regression is found in arts and physical education students rather than other students. 3) There is no sex difference in the levels of freshmen's moral judgment. 4) Freshmen justified the transgressions in moral situations on permissibility and generality. Therefore, they appear to view moral issues as more legitimately subject to moral domain. In part, they tend to view moral issues as subject to conventional domain in that they justify the affairs related to peers of elders on rule-dependence. 5) Freshmen's domain distinction was apparent in that they justified conventional issues on generality. However, they are also seem to moralize since they partly view conventional issues containing relationships with parents as subject to moral domain. 6) Freshmen justified personal issues on rule-dependence and generality. Therfore, it is concluded that they justify the personal issues as subject to conventional domain. 7) Freshmen are more likely to reason about moral issues as personal obligation and sort them as under moral domain. However, within-domain differences in justifications are apparent in that freshmen treated the moral issues as subject to customs or traditions, or personal choice. 8) A strong moralizing is evident in that freshmen conceived conventional issues in terms of other's welfare rather than conventional reason. 9) The within-domain consistence is obvious in that freshment reasoned about personal issues as personal and sort them as under personal domain. However, it is found freshmen's moral conceptions are dependent on situations because some students justified personal issues on other's welfare or obligation while other sutdents did on moral reasons and conventional sanctions or customs.

        This study aims to analyze the moral judgmental levels and the conceptions of transgressions of Korean college students in a series of multifacted events and the aspects of change in terms of moral judgmental level and conceptualizastion after with two years' college experience. The study was based on the Kohlberg's cognitive moral development theory and on the domain-distinction model in which children's intuitive abilities are stressed. This study was consisted of two sub-studies done in 1989 and 1991 respectively. The subjects of the 1st year study were 416 college students in four major cities(Seoul, Taegu, Kwangjoo, and Pusan). The subjects of the longitudinal analysis of second year study were 199 college students who could be followed up among the subjects of the 1st year study after two years. The instruments used in this study were Test of Moral Judgmental Development and Test of Conceptualization on Mulifaceted Events developed by the authors on the basis of Kohlberg's and Turiel's theories respectively. The following conclusions were obtained through the basis of the results and discussions of this study. First, Korean college students' false responses to moral issues decrease but the radical and anti-social responses increase after two years, and ther these responses are replaced by the level Ⅲmoral judgmental responses. Second, college students who are on the higher moral judgmental level conceptualize the transgression in social conventional and personal domains less permissible than those on the lower levels do. The students who are on the lower judgmental level reveal the decrese of nonpermissibility in social conventional domain with two years' college experience than those on the higher level do.
