Experiment was conducted to select the rice varieties and lines resistant to the smaller brown planthopper, Laodelphax striatellus Fallen, and study the cause of varietal resistance to the insect. The nature of varietal resistance was evaluated from the viewpoints of feeding and ovipositional preferences and antibiosis. Among the IRRI sources the varieties H 105, Muthumanikam, Vellailangalayan, Karsamba Red ASD-7. Manavari Co 22, Mudgo, PTB-18, IR 8 and IR 20 were selected as resistant sources. Among the domestic sources. only Suweon 213-1, Suweon 214 and Suweon 215 originated from the IR667 lines were resistant, and other leading varieties ail susceptible. The cause of resistance of rice to the insect seemed to be highly related with the non-feeding preference, not non-ovipositional preference. Nymphal mortality and rate of adult emergence were significantly different from the resistant and susceptible varieties. The rate of adult emergence was significantly lower in the resistant than In the susceptible varieties. The primary cause of lower adult emergence seemed to be due to the fact that the infects were suffered higher nymphal mortality in the resistant than in the susceptible varieties.

The success of a product is only possible on the basis of user preference for products and the user preference for products is greatly influenced by the design. Designers have to understand user preference and convert it into the combination of specified design attribute, and after that they should design products which have the image that they want to get. Then the product will be sure to be a hit. Therefore, on the point of view of design, it is necessary to find oui definitely the consumer preference frame : the relationship among design preference - design images - design attribute. This study will give you guidelines on which designers can select and design some more objective and reliable design factors, finding out the relation of cause and effect by which they can know what kind of product designs their consumers like and how the popular image which that products offer is composed of. Therefore, in this study, after we developed the consumer response framework which is proposed by Bloch(1995) : distinct relationship model among preference - design image adjective - design factors, we analyzed the relationship among preference-design image adjective - design factors through the empirical researches. And then we give the way of design.

When a mail was given to users, each user's response could be different according to his or her preference. This paper presents a solution for this situation by constructing a user preferred ontology for anti-spam systems. To define an ontology for describing user behaviors, we applied associative classification mining to study preference information of users and their responses to emails. Generated classification rules can be represented in a formal ontology language. A user preferred ontology can explain why mail is decided to be spam or ron-spam in a meaningful way. We also suggest a new rule optimization procedure inspired from logic synthesis to improve comprehensibility and exclude redundant rules.

The functional responses of the female Cyrtorhinus lividipennis on brown planthopper (BPH), Nilaparvata lugens, eggs and their predation behavior were investigated at six temperature conditions; 20, 23, 26, 29, 32, and $35^{\circ}C$. C. lividipennis was found to prefer young BPH eggs, especially 3-day-old eggs the most. The functional responses for female C. lividipennis on BPH eggs fitted the Holling's Type-I true predator-prey Rogers' (1972) model at all temperatures tested except $35^{\circ}C$ at which the negative Th value was produced. With the temperature increased up to 32$^{\circ}C$, the instantaneous attacking rate(a) increased from 0.1923 at $20^{\circ}C$ to 0.5085 at $32^{\circ}C$, while the handling time (Th) was gradually decreased as low as 0.0151 at $32^{\circ}C$. C. lividipenis preferred the BPH eggs laid on the upper part of rice stem when the BPH egg density was high, but there was no significant difference in the preference when the egg density was low. The preference was more obvious in high temperature conditions such as above 29$^{\circ}C$.

In this paper, it would be shown that individuals can have different responses to the same email based on their preferences through computing the distributions of user clusters' email responses from clustering results based on email users' preference information. This paper presents an approach that incorporates user preferences to construct an anti-spam mail system, which is different from the conventional content-based ones. We consider email category information derived from the email content as well as user preference information. We also build a user preference ontology to formally represent the important concepts and rules derived from a data mining process and then apply a rule optimization procedure to exclude unnecessary rules. Experimental results show that our user preference based system achieves good performance in terms of accuracy, the rules derived from the system and human comprehensibility.

Experiment was conducted to study resistance of rice varieties and lines originated from Korea and IRRI sources to the zigzag-striped leafhopper, Recilia (Inazuma) dorsalis MOTSCHULSKY The nature of varietal resistance to the insect was evaluated from the viewpoints of feeding and ovipositional preferences and antibiosis. The varieties Su-Yai-20, Muthumanikam, PTB-18 and Vellanlangalayan were resistant and DV-139 moderately resistant to tile zigzag-striped leafhopper, and the other varieties tested were susceptible. Feeding and ovipositional preferences were significantly different among the varieties, but no correlation was observed between the two preferences. The nature of resistance of rice to the insect seemed to be related with The non-feeding preference, not non-ovipositional preference. The resistant (Vellanlangalyan and Su-Yai 20) and moderately resistant(DV-139) varieties had high antibiosis against the zigzag-striped leafhopper.

This study intended to grasp image association on human's product and cognition response characteristic, and analyze their correlation with product preference. For this, photos of mobile phones and proposal-type products were selected for experiment stimuli, and an experiment expressing associated word and an experiment evaluating preference of each product's photo were made. With the experiments, two results were derived. First, in linguistic cognition response on product with use experience, application of emotional expression increased as the level of preference increased by mixing expressions of metaphor languages and emotional image. Second, non-use experience of product induces response corresponding to understanding on the object of cognition only perceptually and considering similarities with general experience information.

The variety Tong-il from the IR667 lines have been reported as a variety resistant to the smaller brown planthopper, Laodelphax striatellus Fallen, in Korea. The resistance of Tong-il to the insect, however, have been mainly evaluated from a viewpoint of plant reaction of rice at the seedling stage. In this study, the nature of resistance of Tong-il to the insect was furthermore evaluated from the standpoints of feeding preference, antibiosis and plant tolerance in comparison with the resistant varieties Karsamba Red ASD-7 and Vellailangalayan. and the susceptible variety Jinheung which have been reported to the insect. The smaller brown planthopper much more prefered Tong-il for feeding than the resistant varieties ASD-7 and Vellailangalayan. The degree of antibiosis of Tong-il to the smaller brown planthopper was significantly lower than ASD-7 and Vellailangalayan. The results showed significantly lower nymphal mortality and higher adult emergence in Tong-il and Jinheung than other two resistant varieties. The degree o( tolerance of Tong-il to the insect was also lower than ASD-T and Vellailangalayan. Only. Tong-il seemed to be relatively more tolerable than Jinheung. The reason of showing resistant reaction of Tong-il in the mass screening test might be related with relatively lower feeding preference and more tolerance than Jinheung and other susceptible varieties.
