The purpose of this study is to observe the rapidly changing men's fashion style in the contemporary society and to analyze the features related to the major-subject groups, male university students. This information could be used for clothing companies to plan commodities, divide markets, and develop designs. The results are as follows. First, several opinions were varied among students' majors. For the opinion about the male students focusing on their external appearance, the students from all majors said that it depends on individual preference. For 4 reasons of external appearances, students from all majors frequently said that they should adjust their external appearance for employment. For the opinion about what is considered the most in the purchase of clothing, most of the students considered about the design of the cloth. For the opinion about influences on the purchase of clothing, major of the students were influenced by their friend or colleague. on the other hand, the students from artistic talent and physical education mentioned other opinion that it depends that it depends on situation and own intention is most important. Second, for the question about clothing behavior, with regard to monthly average shopping control expense, the students from all majors mentioned the amount less than KRW 50,000. For the opinion about the number of shopping, most student mentioned once a season. For the opinion about the store to purchase dress, most students mentioned the use of large shopping mall but the students from business administration and economy mentioned the use of discount store. Third, for the question about preferred style and preferred brand, with regard to the opinion about usual style, the students from all majors have worn casual style. For the opinion about the preferred style, most students mentioned casual style. For the opinion about man's accessory wearing, the students from all majors mentioned that it is good and for the opinion about coordination item, most students mentioned bag.

Complexes M($C_7H_2NO_5)3H_2O{\cdot}H_2O{\cdot}0.25MeCN$ (M=Ni, Co) were crystallized from the reactions of $Ni(CH_3COO)_2{\cdot}4H_2O\;or\;Co(CH_3COO)_2{\cdot}2H_2O$ with KSCN and 2,6-dicarboxy-4-hydroxypyridine (chelidamic acid). The structures were characterized by X-ray crystallography. The crystal structures of 1 and 2 show a distorted octahedral coordination geometry around the M(II) ions, which are chelated by one nitrogen atom and two oxygen atoms of the chelidamic acid and three water molecules. Complexes 1 and 2 display the hydrogen-bonded 3D framework. The magnetic behavior of 2 exhibits antiferromagnetic interaction.

Unlike conventional researches, we are able to i) compare the fuzzy logic based BBA with non-fuzzy BBA for verifying the effective performance of the proposed fuzzy logic application ii) dynamically respond to the intrusion using BBA whereas the previous IDS was responding statically and iii) expect that this would be a cornerstone for more practical application researches (analyzing vulnerability and examining countermeasures, etc.) of security simulation. Several simulation tests performed on the targer network will illustrate our techniques. And this paper applies fuzzy logic to reduce the false negative that is one of the main problems of IDS. Intrusion detection is complicated decision-making process, which generally involves enormous factors about the monitored system. Fuzzy evaluation component model, which is a decision agent in the distributed IDS, can consider various factors based on fuzzy logic when an intrusion behavior is detected. The performance obtained from the coordination of intrusion detection agent with fuzzy logic is compared against the corresponding non fuzzy type intrusion detection agent. The results of these comparisons allow us to evaluate a relevant improvement on the fuzzy logic based BBA.

The purpose of the study was to investigate brand images and fashion leaderships of women's wear manufacturers targeting middle-aged women or older women. Thus, this study was to be an exploratory study to investigate clothing behavior of elderly female consumers and search apprel niche-market for them. The questionnaire consists of questions on brand images, fashion leadership, and merchandise assortment. The subjects were to evaluate their brand images and rated on 5 point Likert-type scales of 29 adjectives. The fashion leadership of these brands was evaluated by the degree of fashion trends adopted on 7 aspects including fashion images, silhouettes, fabrics, colors, design details, accessories, and item-coordinations. For the survey, both interview and the subjects were 66 manufacturers which have national brands or designer brands. Among 44 respondents, 30 respondents were designers and the rest of them were merchandiser or shop managers. The SPSS PC+ package was used to calculate frequency, T-test, and cluster analysis. The results from survey of manufacturers targeting middle-aged women or older women are as follow: 1) The brand imges which they pursue are prestigious, practical, and elegance. 2) There were significant differences in brand images, and national brand manufacturers pursue stronger images in prestigious, chic, intelligent, competency, than designer brand manufacturers. 3) 40 brands were divided into two clusters. 36 brands were included in one cluster, and only 4 brand were belong to the other cluster. In this market, the image of feminity was grouped with the image of prestigious, chic, intelligent, competency. 4) In product planning, the adption level of fashion trends in 7 aspects was generally at medium level, but fashion trends were more adopted in fabric, color, and item-coordination.

The culture phenomenon, which the desire of self expression is noticeable and the diversity of gender identity is widely accepted, simply makes a difference in the lifestyle of one human being rather than the dichotomous classification of male and female. Now, the delicate and aesthetic sensitivity classified as the feminine characteristics is no longer the exclusive property of female and this refers to substituting it as a social gender from the concept of biological sex. This phenomenon has influenced on the male culture and is creating various codes according to the cultural gender extended from the gender as a social role. Also, the transition into the western lifestyle has extended the aesthetic emotion to accommodate new codes from the diversification and globalization of lifestyle. The mansumer power, which does not care too much about the money for the emotionally attached items, has enabled various fashion styles. After analyzing the diversified clothing behavior conducted by these people in connection with the social phenomenon, First, this shows the phenomenon of emotional value pursuit that finds pleasure over the clothing as the item of augmented reality is added to the concept of play, in which the real space referred to as garment and virtual space of playing the rock, paper and scissors game meet together within the augmented reality. Second, the convergence concept has enabled the coordination of new style by obscuring the area of design concept and this refers to the changes in design from the development of new items and transformation into double-style details. Third, the divergence that intensively provides specific use/convenience and specialized value shows a change in the fashion market from the phenomenon that admits various gene rations of culture and specifically, takes differently about the recognition of middle-aged males. Fourth, the variety seeking tendency receives attention as the value of future design together with the phenomenon of discriminative value pursuit. In the male fashion, it is linked to the collaboration with the design area and this tells that the fashion with the narcissistic cross-dressing and motto of neutral gender without being sided to male/female is rising.

The rates of aquation of sparteine cobalt(II) halide and sparteine copper(II) halide were investigated in the citrate buffer solutions. The aquation of cobalt(II) complexes proceeds via D-mechanism and the catalytic effect of halide ions is not observed. The aquation of copper(II) complexes proceeds via $I_d$-mechanism and is catalyzed by the presence of cyanide and halide ions, and the aquation rate is pH dependent. The different mechanistic behavior of cobalt(II) complexes from corresponding copper(II) complexes seems to be attributed to the weakness of Co-N bond in the coordination sphere.

In this study, we tried to scrutinize the status and problems of domestic cosmetics industry. On the basis of theoretical study, we examined the strategic marketing skill and tactics of foreign products to devise a strategy for domestic cosmetics with the help of marketing mix of foreign competitors: so to say 4 Ps. The core of the empirical research is hereby the effect of consumers' behavior. The conclusion of the research can be summarized as following: the most important problem of domestic cosmetics industry is the poor brand power. It has been confirmed that the consumer needs are various and dynamic. Analysis of 4 Ps of marketing factors of foreign goods shows this very clearly. Consumers tend to rely upon the brand name of the product rather than the quality, when they don't have enough information or knowledge on the product. This conclusion teaches us to make an effective strategy of marketing. It is brand power and brand cultivating. This study may give domestic marketers a motive to predict the future and succeed in existence and prosperity.

Background: Panax vietnamensis Ha et Grushv. or Vietnamese ginseng (VG) is a recently discovered ginseng species. Studies on its chemical constituents have shown that VG is remarkably rich in ginseng saponins, particularly ocotillol saponins. However, the psychopharmacological effects of VG have not been characterized. Thus, in the present study we screened the psychopharmacological activities of VG in mice. Methods: VG extract (VGE) was orally administered to mice at various dosages to evaluate its psychomotor (open-field and rota-rod tests), sedative-hypnotic (pentobarbital-induced sleeping test), anti-stress (cold swimming test), anxiolytic (elevated plus-maze test), and cognitive (Y-maze and passive-avoidance tests) effects. Results: VGE treatment increased the spontaneous locomotor activity, enhanced the endurance to stress, reduced the anxiety-like behavior, and ameliorated the scopolamine-induced memory impairments in mice. In addition, VGE treatment did not alter the motor balance and coordination of mice and did not potentiate pentobarbital-induced sleep, indicating that VGE has no sedative-hypnotic effects. The effects of VGE were comparable to those of the Korean Red Ginseng extract. Conclusion: VG, like other ginseng products, has significant and potentially useful psychopharmacological effects. This includes, but is not limited to, psychomotor stimulation, anxiolytic, antistress, and memory enhancing effects.

The reduction behavior of silver ions to silver nanoparticles is an important topic in polymer/silver salt complex membranes to facilitate olefin transport, as this has a significant effect on the long-term performance stability of the membrane. In this study, the effects ofthe solvent type on the formation of silver nanoparticles, as well as the long-term membrane performance of a solid polymer/silver salt complex membrane were investigated. These effects were assessed for solid complexes of poly(N-vinyl pyrrolidone) $(PVP)/AgBF_4$, using either an ionic liquid (IL), acetonitrile (ACN) or water as the solvent for the membrane preparation. The membrane performance test showed that long-term stability was strongly dependent on the solvent type, which increased in the following order: IL > ACN >> water. The formation of silver nanoparticles was more favorable with the solvent type in the reverse order, as supported by UV-visible spectroscopy. The poor stability of the $(PVP)/AgBF_4$ membrane when water was used as the solvent might have been due to the small amount of water present in the silver-polymer complex membranes actively participating in the reduction reaction of the silver ions into silver nanoparticles. Conversely, the higher stability of the $(PVP)/AgBF_4$, membrane when an IL was used as the solvent was attributable to the cooperative coordination of silver ions with the IL, as well as with the polymer matrix, as confirmed by FTIR spectroscopy.

Developmental disability shows life-long behavioral abnormality with no significant physical malformation. This study was undertaken to develop an animal model for developmental disability by using two-factor approach. Lipopolysaccharide (LPS), a bacterial toxin, and NAN-190, a $5-HT_{1A}$ receptor antagonist, were administered to Sprague-Dawley rats on postnatal day (PND) 5 to induce inflammation and an altered 5-HT system, respectively. Long-term alteration of behavior occurred in the drug-treated groups. The LPS-treated group showed impaired motor coordination in the Rota-rod test. The LPS- treated or both LPS and NAN-190-treated groups showed impaired fore-paw muscle power in the wire maneuver test. These groups also showed decreased white matter volume and increased serotonergic fibers. The LPS and NAN-190-treated group also exhibited neurologic deficit in the placing reaction test and impaired equilibrium function in the tilt table test. The results showed that a variety of altered behaviors can be generated by two factor model, and suggested that combination of important etiologic factors and possible underlying defects is a promising strategy of establishing an animal model for developmental disabilities.
