Seven varieties of rice were cultivated in the field of BLRI of which three were native (Maloti, Nizershail and Chandrashail) and four were improved ($BR_3$, $BR_{11}$, Pasam and Mala). Yields of straw and grain were recorded and the chemical composition of straw was determined. Both the grain (p < 0.05) and straw (p > 0.05) yields were higher in the improved than the native varities. Relationships of straw dry matter yield with the hights of rice plants, tiller numbers, levels of N fertilizer and lengths of stover were found to be statistically insignificant. No significant differences were observed among the varieties in respect of NDF, cell soluble, cellulose and hemicellulose contents. However, modified acid detergent fibre and insoluble ash content were significantly (p < 0.05) higher in the local varieties. Except $BR_3$, the estimated ME content of straw was higher in the improved than the native varieties. In respect of yield, chemical composition and energy content improved straws were better and Pasam was the best.

Yuza (Citrus junos) has 3 varieties with variable physiochemical properties. This study analyzed these volatile compounds and physiochemical properties according to variety. Three Yuza varieties, native (Citrus junos I), improved I (Citrus junos I+Poncirus trifoliata), improved II (Citrus junos I+C. junos II) were used. The native Yuza weighted more than the improved varieties, but the peel ratio (weight of peel versus pulp) was high in improved one. Protein and ash contents were high in Improved I than native one. Native had 29.6mg% vit. C in pulp and improved I had 57.7mg% vit. C in peel. Free sugar was mainly fructose, and the main organic acid was citric acid in Yuza. Improved I Yuza had high free sugar contents, and the organic acid levels were high in improved II Yuza. Linoleic acid was the most prevalent fatty acid in Yuza; it was distributed in peel or pulp. The most common volatile flavor component was dl-limonene (64~70%); improved II Yuza showed significantly higher contents of dl-limonen and ${\gamma}$-terpinen. Total phenol level of Yuza was identical in all types, but peels had 2.5 times more than pulps.

Heading behaviour of native japonica (GI) and Japanese varieties (GII) grown during 1910-1920s were thermo-sensitive, home bred varieties during 1930s (GIII) - 1950s (GIV) were photo-sensitive and semi-dwarf indica derived varieties released since 1971 (GV) were controlled by basic vegetative phase. Number of leaves on main culm was increased with varietal improvement and culm length was gradually shortened as variety improved. GV variety had the shortest plant height among the groups. The first internode length was about 30cm in all groups and difference of 2nd-4th internode length was caused shortening the culm length. Panicle length and diameter of panicle neck were shortened and became thinner as variety developed from GI to GIV, however, GV had longer panicle and thick panicle neck, respectively. Number of panicles/hill and straw weight/hill increased and became heavier as variety improve from GI to GIV but GV had moderate number of panicle/hill and relatively light straw weight. Number of spikelet/panicle has been reduced with varietal improvement but GV had the biggest number. Grain yield/hill also increased as variety improved, however, it was decreased as transplanting season postponed and GV had shown the most sensitive difference. Top dry matter weight at heading stage and at 20 days after heading (20 DAH) had no difference among the groups except GI which was the smallest. Average grain weight at 20 DAH was heavier in the order of GI > GII, GV > GIV > GIII. It had a little variation in GI & GII while that of other variety group showed significant decrease as transplanting delayed. Harvest index (HI) of GV was the highest at 54% for the earlier transplanting and GIII had the lowest HI. Difference of HI became conspicuous for the later transplanting, the varieties bred later had the lower HI when transplanting of rice delayed. At the earliest transplanting applied (May 15), the grain yield was higher in the order of GI > GIV > GIII > GII > GI, however, that of Tongil type variety (GV) was the lowest for the latest transplanting (June 29). Interrelationship among the agronomical characteristics and grain yield was discussed.

Data mining technology is frequently used in identifying the intention of users over a variety of information contexts. Since relevant terms are mainly hidden in text data, it is necessary to extract them. Quantification is required in order to interpret user preference in association with other structured data. This paper proposes rating and comments mining to identify user priority and obtain improved ratings. Structured data (location and rating) and unstructured data (comments) are collected and priority is derived by analyzing statistics and employing TF-IDF. In addition, the improved ratings are generated by applying priority categories based on materialized ratings through Sentiment-Oriented Point-wise Mutual Information (SO-PMI)-based emotion analysis. In this paper, an experiment was carried out by collecting ratings and comments on "place" and by applying them. We confirmed that the proposed mining method is 1.2 times better than the conventional methods that do not reflect priorities and that the performance is improved to almost 2 times when the number to be predicted is small.

The purpose of this study was to evaluate the relationship between the diversity of food intake and nutrient intake among Korean college students participating in a nutrition education class via the internet. The subjects were 796 college students throughout South Korea (278 males, 518 females). A 3 days dietary recall survey was conducted and results were analyzed using the Computer-aided Nutritional Analysis Program. Dietary variety was assessed by DDS (dietary diversity score), MBS (meal balance score), and DVS (dietary variety score). Dietary quality was assessed by NAR (nutrient adequacy ratio), and MAR (mean adequacy ratio). As the DDS, MBS and DVS increased, the NAR and MAR improved. The subjects with a DDS of above 4 or a MBS of above 10 or a DVS of above 11 met two-thirds of the Korean recommended dietary allowance for most nutrients. The DDS, MBS and DVS correlated positively and significantly with the NAR and MAR. Associations between the NAR and high levels of DVS were more positive than those between the NAR and the DDS. Based on these results, the food intake of these subjects was not adequate. Specially, the dietary intake of calcium and iron were not adequate. Therefore, dietary guidelines should be made considering nutritional characteristics so as to improve the intake from all of the major food groups and provide a variety of foods in their diets.

The purpose of this study was to assess dietary variety by body mass index, waist circumference and exercise habits in 138 female university students residing in Bucheon and its adjacent area. Body mass index(BMI), waist circumference (WC) and exercise habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average BMI, WC, DDS, MBS, and DVS were $20.7{\pm}2.59\;kg/m^2$, $69.3{\pm}5.03\;cm$, $3.87{\pm}0.57$, $7.27{\pm}1.48$, and $12.59{\pm}3.14$, respectively. The DDS for breakfast, lunch, supper and snack were $1.80{\pm}0.92$, $2.45{\pm}0.48$, $2.49{\pm}0.55$ and $0.53{\pm}0.52$, respectively. DDS, MBS, and DVS were not significantly correlated with BMI, WC and exercise habits. However, DDS for breakfast and supper were significantly higher(p<0.05) and lower(p<0.05) respectivly in subjects who exercised regularly compared to those who did not exercise regularly. And DDS for snack was significantly higher in subjects whose awareness of health status was good or somewhat compared to those whose that was bad(p<0.05). These findings suggest that nutritional education based on female university students' eating variety and regular exercise may be required to improved dietary variety.

In 2010, Jeon-Kim proposed HMAP(Hash-based Mutual Authentication Protocol for RFID Environment) to resolve a variety of problem related to security using Mutual authentication scheme, the hash function and secret key is used to update in RFID system. Jeon-Kim proved RMAP was safe for a variety of attacks including eavesdropping attacks through safety analysis. However, unlike the claims of the proposed protocol is vulnerable to next session of the secret key exposure due to eavesdropping. In this paper, we analyze the problem of RMAP and proves it through security analysis. And we also propose improved an RFID Mutual Authentication Protocol based on Hash Function to solve problems of HMAP.
