Structure-activity relationship studies of allylamine type of antimycotics were carried out to evaluate the effect of naphthyl and methyl portion of naftifine. Compounds with 2,4-difluorophenyl( 2a-5a), 2,5-difluorophenyl(2b-5b), 4-ethylphenyl(2c-5c), 2-hydroxyphenyl(2d-5d) and 2-methylnaphthyl(2e-5e) instead of naphthyl group with hydrogen(3a-3e), methyl(4a-4e), and ethyl(5a-5e) in the place of methyl in naftifine were synthesized and tested their in vitro anti-fungal activity against five different fungi. Eight compounds( 3a, 4a, 5a, 3d, 4d, 4d, 5d, 3e, and 4e) showed significant anti-fungal activity against T. mentagroPhytes. (E)-N-(3-Phenyl-2-propenyl)-2- hydroxy-benzenemethaneamine( 3d) displayed moderate antifungal activity against all five different fungi.

$Moire\'{e}$ interferometry is a useful technique to assess the reliability of electronic package because $Moire\'{e}$ interferometry can measure the whole-field and real-time deformations. The shear strain of a small crack site is important to the reliability assessment of electronic package. The optical limitation of $Moire\'{e}$ interferometry makes ambiguous the shear strain of a small area. An atomic force microscope (AFM) is used to measure the profile of a micro site. High resolution of AFM can apply to the $Moire\'{e}$ technique. AFM $Moire\'{e}$ technique is useful to measure the shear strain of a small area. In this research, the method to accurately measure the deformation of a small area by using AFM $Moire\'{e}$ is proposed. A phase-shifting method is applied to improve the resolution of AFM $Moire\'{e}$.

The Internet is changing old organizational schemes, including education. A growing number of universities are creating curriculums to reflect these changes. Economic market is being opened to the international world, and in order to overcome the difficulties are demanding continuous supply of men power from university to efficiently manage human resource and implement superior e-business model. Technology innovation plays an important role in the sustainable grows of the firm in the global economy. The objective of this study is to suggest an e-business curriculum for e-business department. We will analyze what kind of people is needed for e-business, and provide appropriate curriculum for educating suitable human resources, which could be for university program. This study may contribute to the much needed systematic analysis for e-business curriculum. We prioritize e-business curriculum selected and rank their importance through an exploratory study for suggesting the undergraduate curriculum.

As the rapidly changing e-business environment and development of IT, it is difficult to predict appropriate demand and supply of human resources in e-business industry. Such problem causes the imbalance of needs in demand and supply and the difficulty of proving useful information about fostering necessary e-business human resource and so forth. This study present a manpower training plan in e-business industry by investigating e-business human resource in the market and by analyzing curriculums in selected universities. To achieve this objective, we conducted a survey study of e-business companies, educational organizations and workers. From the results of this study, we present the current status of e-business human resource market and the problems of past manpower training system, and provide recommendations. This study would help policy makers, the private companies and academic institutions in developing effective strategies for the e-Biz human resource sector.

The World has been rapidly changing into either technological aspects or perception of those who has utilised to the corresponding informational impact. Whatever areas we have actually been involved in are strongly connected with this evolution of informational technology in one way or another. Logistics is not a exception as well as trade. Two main routes in distribution channel such as commercial and physical flow of goods, have been operating in terms of I-business. In order to activate E-trade with E-commerce, E-logistics should be utilised and emphasized in more efficient and effective manner of doing job as a facilitator. So, in this paper, it studied the role of E-logistics to make E-trade better work as well as to look into present situations in E-commerce. Then, it was identified that some facilities as 3PL or shipping company have to adopt information in their business process with a view of valued add service providers. This means those who have implemented E-Logistics activities, should be more competitive in the market, only when they provide the value-added total logistics services.

Let E be a real Banach space. Let T : E longrightarrow E be a map with F(T) : = { x $\in$ E : Tx = x} $\neq$ 0 and satisfying the accretive-type condition $\lambda\$\mid$x-Tx\$\mid$^2$, for all $x\inE,\;x^*\inf(T)\;and\;\lambda >0$. We prove some necessary and sufficient conditions for the convergence of the Mann iterative sequence to a fixed point of T.

The International Chamber of Commerce (ICC) eUCP came into force on 1 April 2002. The eUCP is a supplement to the current existing Uniform Customs and Practice for Documentary Credits (UCP500), which governs the use of electronic presentation. The eUCP is not a revision of the UCP. It is a supplement intended to deal with situations where presentations are made electronically. That is to say, the eUCP is a supplement to the UCP that, when used in conjunction with the UCP, will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. The purpose of this paper is to study on the criterion of examination of electronic records under the eUCP.

E-shopping is traditional method to purchase products in a modern society. Fashion products are one of the most popular product categories sold and impulsively bought online. This study examined the causal relationship of shopping value, positive emotion, urge to buy impulsively, and e-impulse buying in the context of shopping for apparel products. A self-administered questionnaire developed from the literature was administered in class to 501 female college students in Busan. AMOS 21.0 estimated the structural equation model of e-impulse buying using a correlation matrix with a maximum likelihood. The analysis of the data supported most of the predictions. The results suggested that consumer shopping values (hedonic shopping value and utilitarian shopping value) had a positive effect on positive emotion; in addition, positive emotion urge to buy impulsively directly affected the e-impulse buying of apparel products. In the structural model, e-impulse buying of consumers can be predicted by the attitudinal component (e.g., shopping values), emotional factors (e.g., enthusiastic or proud), and the urge to buy impulsively felt by young consumers. There are implications that both positive emotion and impulsive buying are important predictors for the e-impulse buying of apparel products by consumers. Moreover, the urge to buy impulsively was an important mediator to determine the e-impulse buying of apparel products. This study provides insight to retailers and researchers to understand the structural relationship of consumer characteristics and the e-impulse buying of apparel products.

This study was conducted to investigate the genetic analysis of esterase isozymes in maize with tillers. The materials used for the study were stele tissue for five day old seedlings of IK inbred line with tiller and A-type inbred line with no tiller, their Fl and F,. The methods employed for the study were same as previous report by Lee and Choe. A total of thirteen isoesterase enzyme bands were identified and five zones were distinguised according to both migration distance and genetic segregation patterns. The E$\sub$0.3/, E$\sub$0.4/ and E$\sub$0.5/ loci appeared from orgin to 0.5cm migration distance were controlled by the two alleles in (IK/A-type)F$_2$ and the E$\sub$0.3/+E$\sub$0.4/ of variants was controlled by codominant alleles. The E$\sub$1.0/, E$\sub$1.2/, E$\sub$1.5/ and E$\sub$1.8/ loci appeared from 1.0cm to 1.8cm were also controlled by the two alleles. However, the null band was functioned alleles. The E$\sub$2.8/, E$\sub$3.0/ and E$\sub$3.5/ loci appeared from 2.8cm to 3.5cm migration distance were very active and near location. A total of individuals with two paried bands of these loci were more than those of three paired bands(x$^2$=0.327$\^$**/). The activity of bands appeared over 3.8cm were very low and these were controlled by the two alleles. In above results, genetic segregations of stele tissue of maize with tillers were suggested to be controlled by Mendelian genetic laws.
