This study aimed to assess the attraction effect against Lycorma delicatula and antioxidant activity of hexane, chloroform, butanol and water fraction obtained from Ailanthus altissima methanol extract. The attraction effect of chloroform fraction showed the highest activity (47%) as compared to that of other fractions. In the DPPH radical scavenging activity, methanol and butanol fraction showed higher antioxidant activity than other solvent fractions. From the above results, the potential chloroform fraction was further performed by local irritation test in New Zealand white rabbits. In eye irritation test, chloroform fraction showed moderate irritant at high concentration 0.5 g/site/mL, but there was no eye irritation at low concentration (0.05 g/site/mL). In accordance with the Draize evaluation of skin irritation, the primary irritation index was calculated to 3.3 and 0.68 at high (0.5 g/site/mL) and low concentration (0.05 g/site/mL) causing moderate and mild irritation, respectively. On the basis of this study, Ailanthus altissima chloroform fraction could be safely considered to be a candidate of attractant against Lycorma delicatula.

The purpose of this study was to find out effects of textile motifs and the application methods on wearer's image perception. A survey was conducted to total of 255 male and female university students who are residing in Daejeon and Chungnam province. The stimuli were composed of 2 level tones(dark and light), 3 level complexity(simple, medial and complex), 3 patterns(polka dot, stripe and check) and the 2 way of stimuli application methods(fabric and garment). The instrument for measuring preference of stimuli consisted of 4 items, encouraging, preference, purchasing and popularity. The instrument for measuring image of stimuli consisted 24 pair items. Factor analysis for the adjective pair images(24 inquiries) about the textile patterns which were used in this study was performed. It resulted as three factors which are attraction, salience, and potential. Attraction, salience, and potency dimensions showed the most significant interaction effects of application methods and patterns. And tone and application method effected attraction and salience, tones and patterns effected attraction, tones and complex effected salience. Application methods and patterns effected potential and patterns and complex effected salience. The preferences toward stimuli, it resulted only interaction of tones and patterns affected the preferences('total preference' and 'purchasing'). Pearson's product-moment correlation analysis carried out to find out the relation of images of clothing and preferences. As a result, salience was significant relation with attraction and potency. In correlation between image of textile pattern and preference, attraction is most significant relation with the preference. The results of the study could be used for the marketing strategies of the motif in fashion product.

This paper investigates the circumstances and conditions of Mokpo Port to develop it as an international logistics stronghold and seeks scheme to maximize the local economic ripple effect through construction and activation of Mokpo New Port. Under the circumstances in which neighboring ports vying with each other have built broad spheres of influence, and competition among ports becomes fierce, a priority cargo attraction strategy should be established by using Mokpo's favorable location compared to other ports in order to ensure that a large quantity of goods is transported from Mokpo New Port. Especially, Mokpo New Port needs to be developed as a vehicles-only exporting port, as well as a port for used car exports and an import port for stones and timber.

The striped fruit fly, Zeugodacus scutellata (Diptera: Tephritidae), is one of important pests in Cucurbitaceae plants. The cuelure is currently using with various forms for surveillance to the Z. scutellata male as well as Z. cucurbitae, Z. tau, and Bactrocera tryoni, which are categorized as prohibited-quarantine fruit flies in Korea. This study was conducted to verify the attraction effect of applying the cuelure in different forms in field conditions. In this study, we used cuelure by 3 different forms as solid, liquid, and wax to striped fruit flies using the Steiner trap. The trap was placed in two Jeju and one Gyeongbuk regions and the number of attracted flies by each cuelure form is monitored by every 2 weeks during 2021. Attraction effect on Z. scutellata was significant difference by different cuelure forms in two Jeju regions. Liquid and wax forms of cuelure showed high attraction number to the Z. scutellata male compared with solid form when flies were occurred with high population from July to August in Jeju. However, there was no significant difference on attraction effect at low population in Juju and Gyeongbuk by different forms. Based on field assay, liquid and wax form of cuelure are recommended for surveillance against Z. scutellata male. Furthermore, these results also strongly suggest that the attractant, liquid and wax forms of cuelure, could be effective for surveillance to quarantine fruit flies such as Z. cucurbitae, Z. tau, and B. tryoni in Korea.

Two congener species of Grapholita molesta and G. dimorpha have similar host ranges and adult occurrence patterns. In addition, the two species commonly use cis-8-dodecenyl acetate (Z8-12:Ac) and trans-8-dodecenyl acetate (E8-12:Ac) as their major sex pheromone components. The commercial lures made of the two components, therefore, suffer a mixed attraction of these two species. This study was conducted to assess any effect of their known minor sex pheromone components to reduce the mixed attraction. When cis-8-tetradecenyl acetate (Z8-14:Ac) was added to the commercial sex pheromone consisting of Z8-12:Ac/E8-12:Ac = 85/15, the attraction to G. dimorpha was not affected, but its attraction to G. molesta was significantly reduced. However, the addition of either dodecanyl acetate (12:Ac) or tetradedecanyl acetate (14:Ac) did not influence on the attraction of both species to the commercial lure. The addition of E8-14:Ac to 3-component sex pheromone, Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10, the attraction to G. dimorpha was rather significantly suppressed. From these results, the 3-component sex pheromone, Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10 was suggested as an improved composition of sex pheromone lure for G. dimorpha.

The purpose of this experimental study was to examine the effects of attitude similarity and ingroup/outgroup membership on interpersonal attraction. 2(Attitude similarity: Similar/Dissimilar) × 2(Group membership: Ingroup/Outgroup) between-subject design was used. The results revealed the significant main effect of attitude similarity. That is, participants preferred a person who had similar attitude with him/herself compared to the person who had dissimilar attitude. Furthermore, the significant 2-way interaction effect revealed that attitude similarity produced greater attraction for ingroup than for outgroup members and attitude dissimilarity produced stronger repulsion effects for ingroup than for outgroup members. These results could contribute to workplaces and organizations by suggesting that considering attitude similarity between team members could be a way to improve organizational productivity. The necessity for expanding these results to research on work-team performance and improvement of organizational productivity was discussed.

This study analyzed the influence of other customers' perception (similarity, physical attraction, and suitable behavior) of the fashion retail environment on male customers' store attitude and behavioral response. In addition, comparing the effect of store type, this study comprehensively provides the effect of other customers' perception in fashion retailing. In order to investigate research questions, an online survey was conducted and 220 responses were analyzed using AMOS 18.0. The results of this research were as follow. First, the dimensions of physical attraction and suitable behavior of other customers influenced toward target customer's fashion store attitude. Second, the effect of store attitude towards the perceiver's behavioral response was proven. Third, customers established their store attitude by other customers' physical attraction in luxury stores, while others' behavior was meaningful in SPA store. Fourth, other customer's similarity dimension did not influence the male customers' store attitude. This study contributes to a comprehensive understanding of other customer's effect in fashion stores by examining different store types. In addition, managers may establish a customer portfolio strategy and training based on this research.

This study is directed to examine the most useful restoration strategies for turning the customers' dissatisfaction caused by unsuccessful spa service to the satisfaction through each fair factors and tries to suggest the practical schemes to cope with complaints and dissatisfaction of spa service customers by establishing the system dealing with customers' complaints. And this verifies the relationship between the alternative attraction and the intention of conversion as the action after the restoration from the unsuccessful services. Moreover, it analyzes the mediation effect that a formation of reliance through the restoration of unsuccessful services has. To achieve the purpose of this study, the subject got decided as women who are customers of private spa facilities situated in Seoul and Gyeonggi-do region for the purpose of skin care in 1 year recently. After understanding their experiences of complaining about the services, this study investigates the alternative attraction and the intention of conversion as the next action and the perception of fairness and trust in the efforts of Spa service business for recovery. As the result of verifying hypothesis, it is shown that the recovery satisfaction increases when the 3 points of the distributive justice, procedural justice, and interactional justice, which are the fairness factors of the effort to restore services according to the quality of service, are more positive. In the relation among recovery satisfaction, trust, the alternative attraction, and the intention of conversion, the result was that recovery satisfaction affects trust in positive way and alternative attraction in negative way. However, the positive and meaningful result came out in contrast with the hypothesis which predicted the negative effect of recovery satisfaction on the intention of conversion. Furthermore, it means that indirect effectiveness which carries trust and alternative attraction should be considered instead of the direct effectiveness that the recovery satisfaction affects on the intention of conversion. In this study, it can be interpreted that the combined increase of the trust and the alternative attraction makes the intention of conversion higher rather than the higher intention of conversion following the decrease of the recovery satisfaction in view of the result that the indirect effectiveness is high between the recovery effort and the intention of conversion. In the relation among the intention of conversion, trust, and alternative attraction, the intention of conversion got influenced in positive way and negative way by trust and alternative attraction respectively and trust influenced the alternative attraction negatively as well. It means the high quality of services or the recovery of services has a direct causation which carries conviction to the customers' intention of action.

This paper presents a characteristics of linear induction motor considering airgap variation for railway transit in order to achieve high performance of the vehicle. The operating principle of a LIM(Linear induction motor) is identical to a rotary induction motor. Space-time variant magnetic fields are generated by the primary part across the airgap and induce the electro-motive force(EMF) in the secondary part, a conducting sheet. This EMF generates the eddy currents, which interact with the airgap flux and so produce the thrust force known as Loren's force. Even though the operating principal is exactly same as a rotary motor, the linear motor has a finite length of the primary or secondary parts and it causes static and dynamic end-effect which is the discontinuous airgap flux phenomenon. This end-effect causes the deterioration of the system performance, especially in high-speed operation. Another problem is that construction tolerance restricts the minimum airgap in order to prevent a collision between the primary part and the secondary reaction plate. More over, as the airgap length is getting smaller, the attraction force between the primary part and secondary parts is getting larger dramatically and the attraction force would be another friction against propulsion. Therefore, it is necessary to figure out the characteristics of linear induction motor considering airgap variation in order to achieve high performance of the vehicle. The dynamic model of LIM taking into account end-effects is derived. Then the modified mechanical load equation considering the effect of the attraction and thrust force according to the airgap variation is analyzed. The simulation results are presented to show the effect of the LIM according to the airgap variation.
