  • This study is intended to look for implications through longitudinal exploratory research on the change of children's problem behaviors for their temperament and parenting behaviors. The results are as follows. The factors influencing children's problem behaviors rose to 62 factors between 1990 and 2000, and 93 factors between 2000 and 2010 from total 41 factors between 1970 and 1990, which they were more than doubled after the 2000s compared with the earlier studies, subdividing children's problem behaviors. The proportion of the factors influencing children's problem behaviors showed that parents' moral thinking had the highest, and their negative thinking or emotion for children were higher than their moral thinking, which their problem behaviors were more greatly affected by parenting attitudes toward them than their own temperament or attitudes. The earlier studies were more likely to find the cause of children's problem behaviors for looking into the factors and causes influencing children's problem behaviors in terms of children's personal mental health, but there was more proportion of social environment, peer and teacher relationship while soaring family, relationship, home environment and child care center environment factors as well as children's personal factors after the 2000s. Consequently, the alternative resources or the environments of the times should be applied in other ways.

  • Several geophysical surveys(electrical resistivity, electromagnetic, seismic refraction, CPR) were conducted to primarily investigate the gallery and the geomembrane at an abandoned mine(Imcheon mine). The subsurface structure mapped from seismic refraction survey mainly consists of three velocity layers(>1000 m/s, 1000∼2000 m/s,<2000 m/s). Top of the bedrock, whose velocities exceed 2000 m/s, appears to be at depth of 7.5∼10m. Higher resistivities (of ten thousands-hundred of thousands ohm-m) are interpreted to be associated with a open(cavities) gallery. The events at depth of approximately 0.5∼0.7m in GPR sections are probably caused by high-density-poly-ethylene geomembrane. Taking into consideration of the differences in the spatial resolution between georadar and electrical surveys, the events of geomembrane correspond to the top of the high resistivities at depth of about 2m. The segments, characterized with the higher conductivities in the electromagnetic data and the lower resistivities in the electrical resistivity data, are probably associated with surface water or tear zone of geomembrane.

  • Rahnella aquatilis AY2000 has an unique characteristic which produces an anti-yeast substance (AYS). The AYS of the strain AY2000 was always secreted on agar plate, however, its activity in liquid culture was labile upon storage of the medium. In this paper, cultural conditions of the strain AY2000 for the AYS production were investigated in liquid culture, and minimal inhibitory concentration (MIC) against Saccharomyces cerevisiae was determined for the AYS activity. MIC of the AYS cultured in PYG broth at $^25{\circ}C$ for 24 hr was $23.5{\mu}g/mL$, however, that in MYCS (pH 5.5) broth at the same condition was $15.5{\mu}g/mL$. The activity of the AYS had increased rather in MYCS broth excluded $NH_4$-citrate than in the same broth contained $NH_4$-citrate, and MIC of the AYS produced in MYCS broth without $NH_4$-citrate was $15.5{\mu}g/mL$. When the strain AY2000 was maintained in MYCS broth without $NH_4$-citrate but added $100{\mu}M$ $FeCl_3$, the activity of the AYS had increased and its MIC was $7.8{\mu}g/mL$. MIC of the AYS was $7.8{\mu}g/mL$ after the strain AY2000 was cultured in MYCS broth containing $100{\mu}M$ $FeCl_3$ without $NH_4$-citrate, however, its MIC was $31.3{\mu}g/mL$ after 48-60 hr culture in the same broth.

  • The goals of this study are to analyze how fashion professionals' attitudes toward Grunge style have changed since the 1990s and to compare aesthetic features of 1990s Grunge style and the style since 2000. By searching Vogue and Women's Wear Daily articles from 1992 to 2014 according to the keyword "Grunge", three collections from the 1990s and 59 collections since 2000 were selected for analysis. Although Grunge collections of the 1990s were harshly criticized by critics and retailers as ugly, the more recent collections have been highly praised for both design and profitability. The common aesthetic features of Grunge style in the 1990s and beyond include loose silhouettes, mix-and-match layerings, plaid patterns, floral prints, and striped patterns. However, Grunge style since 2000 has new features such as ornate fabrics, handcrafted details, a formal and dressy look, and faux plaid flannel shirts in chiffon or organza. These features give the style a more luxurious, feminine, and refined appearance. The results of this study indicate that Grunge style of the 1990s changed high fashion beauty standards and today's designers and consumers prefer to mix various styles to create new ones. They typically do not consider the original spirit or identities of the varied styles.

  • Since Homeros in Greece, Mimesis was thought to be an art to imitate the nature, and it means an imitation of the nature classically. Mimetic theories were set to be a kind of art work in the era of Renaissance, and the terminology of mimesis was widely used to replace it with an originality in the 15th century. The purpose of this study is to understand the aesthetics of mimesis expressed in 2000s fashion. For this purpose, I investigated the theories of the mimesis, categorized the definition, then applied those categories for 2000s fashion. Documentary studies were conducted through aesthetics, fashion books and demonstrative studies were processed by analyzing photos from collection fashion magazines and fashion site of internet. In the history of aesthetics, the mimesis could be defined into three categories; the similarity and the representation mimesis, the symbol mimesis and the abstraction mimesis. In fashion, the representation mimesis included a natural and a folk, a period that of 1900s and ancient representation mimesis. The symbol mimesis included psychology and fear symbol mimesis. The abstraction mimesis included hard color, a geometric simplification and distortion mimesis. Analysis on the mimesis expressed in 2000s modern fashion may provide an excellent method for understanding human aesthetic in costume.

  • The International Chamber of Commerce introduced in September 1999 its new publication Incoterms 2000(ICC Publication No 560). The ICC was building on the past experiences in its revision works. I have discussed and commented constructively some main features and problems of the new set of terms. Incoterms 2000 takes into account, like already its predecessor did, the possibility that the parties may decide to communicate electronically and replace a paper transport document by an equivalent electronic data interchange message. This possibility will certainly be much more used under the present set of terms. Incoterms 2000 is well recognised by the international legal community, taking into account also the endorsements by UNCITRAL to its predecessor in the early 90's. Incoterms 2000 does not have major competitors remaining. However, the ICC still faces a battle to convince more traders to refer to its terms and to teach traders to understand and to apply them correctly. Incoterms 2000 is a tool for international trade created by a global business organisation. Its members decide every day if and to what extent they make use of this tool. The members of the ICC have participated actively in the drafting and commenting of Incoterms 2000 and thereby shown again a great deal of dynamism in creating rules for their own everyday use. Under these circumstances, "ship's rail approach" related to delivery point, risks and costs should be replaced by "on board approach" under FOB, CFR and CIF terms.
