Increasing concern about a rice quality, it is considered postharvest technology as well as cultivation management as an important factor. Therefore it is necessary to find optimal drying, storage method that did not affected a rice quality. In order to find the optimum storage period of rice, the rice quality was investigated during storage period. The temperature and humidity of storage bin were greatly changed but those of rice were a little do. The germination rate was slowly decreased as the storage period is long. The content of moisture was affected by a room temperature, it was increased at stored rice in rainy season(10-Jul~20-Jul). As storage period is long, the content of amylose, fatty acidity were a just Little changed but did not showed a constant tendency to it. The content of protein was increased and mechanic palatability value was decreased during storage period. The chromaticity of milled rice showed a range of lightness(L); 75.15~71.75, redness(a); 0.21~0.91, yellowness(b); 16.78~19.28 during storage period.

An easy and rapid resistance detection protocol for the Western flower thrips Frankliniella occidentalis was established based on the residual contact vial bioassay (RCV), in which insecticide resistance levels can be estimated at 8 h-post treatment of diagnostic doses. The RDA strain was used as a reference susceptible strain, which has been reared under laboratory conditions over 10 years without exposure to any insecticides. Seven insecticides were tested for the determination of diagnostic dose. Among them, five insecticides (chlorfenapyr, acrinathrin, spinosad, emmamectin benzoate and thiamethoxam, ranged as 0.03 ~ 0.42 μg-1cm2) were applicable to the RCV. However, two insecticides (omethoate and imidacloprid) were not able to be used for the RCV because the treated inner surface of glass vials by these insecticides were too viscous, causing non-specific mortality. The RCV detection kit was employed for the estimation of resistance levels for the five insecticides in five local populations. Almost field-collected populations revealed high levels of resistance to the four insecticides (acrinathrin, spinosad, emmamectin benzoate and thiamethoxam) by showing less than 50% mortality. The baseline resistance detection by RCV method will facilitate the selection of proper insecticides for farmers to manage insecticide resistant-populations of F. occidentalis.

The purpose of this study is to verify The difference between preference group and non-preference group on volunteer recognition and reward on the volunteering participation behavior, motives, satisfaction. The analysis shows that, in the respects of the volunteering participation behavior, total accumulated time of voluntary activities of the group who has recognition and reward preference is more. In terms of participation motives, recognition and reward preference group is the higher of the two about the value recognition motives, the self-development and self-satisfaction motives, the social relations motives except the economic motives. And in volunteer work satisfaction, satisfaction of the recognition and reward preference group is the higher. As a result, preference group on volunteer recognition and reward is positive in comparison of non-preference group on the volunteering participation behavior, motives, satisfaction. This means that recognition and reward in the volunteer activity needs. But the difference between preference group and non-preference group does not appear in the economic motives. Therefore we have to be careful of material aid, because manage volunteer activity by material aid like money has the possibility of injuring the natural meaning of the volunteer activity.

Two different forms of exercise(aerobic and resistant) were divided into two groups and the combination of different order of aerobic and anaerobic exercises was carried out for 4 weeks. Thus, the purpose of this study is to examine the effects of exercise program with different order on lower extremity strength and static balance The isokinetic strength was measured by using the Isomed 2000(Germany). Peak torque/weight of flexion and extension of knee were measured at angular velocity of 60°/sec. The static balance ability was measured by using the Pedoscan(Germany). The results of this study are summarized as follows. For changes in isokinetic lower extremity strength, right and left sides of peak torque flexion weight, peak torque extension weight based on the order of combined exercises for 4 weeks showed statistically significant difference(p<.05). However, there was no significant difference between two groups. For changes in static balance ability, the mean velocity and sway area showed statistically significant difference (p<.05). However, there was no significant difference between two groups.

The purpose of this study is to inspect the possibility of changing teacher-centered language learning into learner-centered one emphasizing learner’s interaction with self-directed learning contents available on-line for high school students. This study is to develop onㆍoff blended contents and apply them into classroom environment. It also discusses the kind of contents teachers and learners want to use. Reading parts for each lesson are usually dealt for three class hours in high schools. So it is designed that the first and the third period are done through off-line classroom and the second, on-line. Well-linked with the first and third period, on-line contents for the second period were designed, developed and applied into educational environment. More than expected number of teachers and learners were pleased with on-line contents reaching 80~90% of high level in satisfaction and also showed 65% reaching learners’ interaction rate in off-line classroom. If on?off blended learning model is well structured based on enough researches, it will realize its strong potential as a desirable learning model for reading.
