Twenty six species of 8 genera of the Korean Cochylini belonging to Tortricidae, excluding a genus Phalonidia, are recognized during the course of this study. Among them 7 species, Aethes citreoflavus Kuznetsov, Cochylidia heydeniana (Herrich- Sch$\ddot{a}$ffer), C. moguntiana (R$\ddot{o}$sier), Eupoecilia angustana (H$\ddot{u}$bner), E. kobeana Razowski, Pseudargyrotoza calvicaput (Walsingham), and Stenodes cuspidatus Ge, are reported for the first time from Korea. A key to the genera is given. Male and female genitalic structures of 7 unrecorded species are briefly redescribed and illustrated.

The WSDL is the specifications which defines the fact that must describe a web service how with the XML. It uses the WSDL and the client discovers a web service and the opening to the public function which the web service provides calling there is a possibility of doing. In this paper application shows the WSDL definition of a simple service providing Slip data process. The service supports a triple web method called WriteSlipXMLFromSql, WriteSlipXMLFromSqlProc, InsertSlipDataToDb which is deployed using the SOAP protocol over HTTP. In this paper, Our proposed web services are expected to contribute to constructing useful world wide web services which are essential in building E-Commerce society.

The practical application of riblet to three dimensional double model, for viscous drag reduction, was studied analytically by intergal solution to three dimensional turbulent boundary layers. The case of a V-groove riblet technique on the shear stress and boundary layer velocities were incooperated in the computation of the flow over a smooth slender ship hull. As the results the possible mechanism of turbulent drag reduction by riblets are then suggested based on detailed studies of near-wall turbulence characteristics. And a turbulent boundary layer calculation scheme based on a momentum integral method was modified for the computer program. An example of the calculation results is presented.

Adsorption experiments were carried out with several clay minerals and PCP hexane solution in order to clarify the status of adsorbed PCP on the clay surface. The amount of PCP adsorption on clay minerals was much greater in the clay-hexane system than in the clay water system. Among the clay minerals, allophane and imogolite ($SiO_2/Al_2O_3$ ratio of about 1) were the most efficient adsorbents of PCP. The PCP adsorption from hexane solution was greatly hindered by the presence of water, suggesting the occurrence of adsorption by a dipole-dipole interaction. PCP adsorption is dependent upon the nature of the clay surface and the exchangeable cations rather than the total surface area.

Black tea extractbsupplemented with 10% sucrose was fermented by fungus at 30$\circ$C. A pellicle thick as 7$\sim$8 mm covered entire surface of the medium and the wxtract converted to acidic beverage(abbreviated below as fermented black tea) by 14 days of fermentation. It was a kind of acetic acid fermentation depending on symbiotic microorganisms. During the fermentation strains of yeasts(Saccharomyces cerevisiae and Eeniella sp.)and bacteria(Bacillus subtilis, Kurthia zopfii, Gluconobacter oxydans and Deinicoccus sp.) were isolated from aqueous layer. Contrastly to it, a bacterial strain(Acetobacter aceti) was isolated from thick pellicle. The bacteria grew as a viscouse cluster on solid agar medium differently from usual strains of A. aceti. Fermented black tea had sweet-sour taste and sweet smell.

Wrap accounts are customized financial services for which investment companies and stock brokers manage investors assets based on their preferences. The success of wrap accounts depend upon the accurate understanding of investment risk propensity and the proper designing of financial portfolio. To this end investment companies should accurately measure investors investment risk propensity with calibrated measures. There, unfortunately, exist few highly calibrated measures of investment risk propensity. Therefore the practices of marketing strategies and customer management often turn out to be less effective and fragile to competition. The purposes of this present study aim to understand the investment risk propensity of wrap accounts customers, to help classify the customers based on the degree of the investment risk propensity, and to implement relevant marketing strategies for different groups of customers. Based on previous studies, two hypotheses were delineated and verified. The findings of the study should help differentiate prospective customers into unique and accessible segments for further targeting and positioning wrap account markets.

An experimental study was performed to observe the in vivo effects of praziquantel on the light and scanning electron microscopic morphology of Fibricola seoulensis. The metacercariae were obtained from the snakes and 1, 000 in each number was orally given to total 15 albino rats; 5 controls and 10 treatment group. Seven days later the 10 rats were treated with 10 mg/kg praziquantcl and sacrificed 1~24 hours later to search for the worms from their small intestines. The major light microscopic changes in the drug-exposed worms were early contraction followed by relaxation of especially their forebody, vacuolization of the tegument and subtegumental parenchymal layers, and narrowing of the intestinal lumens. The scanning electron microscopic findings were characterized by formation of numerous blebs followed by rupture and subsequent destruction of their whole teguments. These results show that the change in worm body is not confined to the tegument but extends to deeper parenchymal portions and also occurs in their intestines. It is suggested that the drug uptake by the worms should be either through their tegument or through the digestive tract.

Trust affects marketing practices and purchasing performance in the context of buying and selling business services. Despite the importance the previous studies on business services have not fully investigated the role of trust and the effects of trust on buying and selling strategies. Additionally in-depth studies exploring the links between trust-strategies-performance have not systematically performed both in domestic and international markets. This study, in the context of purchasing business services, investigates the effect on trust of suppliers' characteristics and relational characteristics between sellers and buyers. This study also explores the effect of trust toward sellers and buyers on purchasing performance. The results of this study should contribute the understanding on the role of trust in purchasing and selling business services. Building and maintaining trust must be one of the major key success factors in the relationship between sellers and buyers of business servies.

An experimental study on the air-side pressure drop of slit fin-tube heat exchanger has been carried out. The data reduction methodology for air-side pressure drop in the literature is not based on a consistent approach. This paper focuses on method of data reduction to obtain the air-side performance of fin-tube heat exchanger using R22 and recommends standard procedures for dry and wet surface pressure drop estimation in fin-tube heat exchanger. A comparison was made between the predictions of previously proposed empirical correlations and experimental data for the air-side pressure drop on design conditions of condenser and evaporator. Results are pre-sented as plots of friction f-factor against Reynolds number based on the fin collar outside diameter and compared with previous studies. The data covers a range of refrigerant mass fluxes of $150{\sim}250\;kg/m^2s$ with air flows at velocity ranges from 0.38 m/s to 1.6 m/s.

Tax-Refund System for foreign tourists is constantly increasing trend because of the discount effect of product. However, in order to get Tax-Refund, foreign tourists are supposed to keep a refund statement of paper issued after the purchases and the existing refund windows involve complicated procedure and poor accessibility, which causes the inconvenience. After recognizing the problems, K company has implemented information systems to relieve the discomfort of the Tax-Refund service by streamlining and reforming complex and inconvenient procedures of the Tax-Refund service so that it is able to plan the shopping convenience of foreign tourists. The K's information system is considered good practice to show that they can play a key role under the competitive environment with the corporate information system that is an essential element in achieving a competitive advantage.
