Jogwang is a new early maturing japonica rice developed in 2007 from a cross between Milyang187 and YR21113-B-B at the Department of Functional Crop Science, NICS, RDA. This cultivar is very suitable to the rice-cash crop double cropping system. Heading date of Jogwang is 2 days earlier than Keumobyeo under the late transplanting cultivation on July 10 at the Yeongnam plain. The tolerance level of this variety to leaf discoloration at seedling stage is very similar to Keumobyeo. It showed slightly lower viviparous germination and premature heading. This cultivar showed resistant reactions to leaf blast and rice stripe virus disease but susceptible to bacterial blight disease and major insect pests. The ratio of milling and head rice recovery of Jogwang is 76.5% and 64.5%, respectively. The milled kernels are translucent with non glutinous endosperm. This cultivar has 7.3% protein and 18.5% amylose content. In local adaptability test, showed that the milled rice yield of Jogwang is $4.90\;MT\;ha^{-1}$. This cultivar is suitable for planting in the plain paddy fields of Honam and Yeonnam regions in Korea.

생활수준 향상과 주 40시간 근무제 도입등에 따라 해양성 휴양 및 관광 수요는 증가하고 있으나 이를 수용할 수 있는 어항 기반은 매우 취약한 편이다. 다양한 관광수요를 만족시키는 환경친화적 관광기능어항 개발이 절실한 실정인 것이다.

Junamjosaeng is a new japonica rice cultivar developed in 2006 from a cross between Milyang165*3 and Koshihikari at the Department of Functional Crop Science, NICS, RDA. This cultivar is suitable for the double cropping system (i. e., before and after the cash crop). Heading date of Junamjosaeng is 6 days earlier than Keumobyeo under the late transplanting cultivation on July 10. It has a high grain fertility under cold conditions and low premature heading. One of the distinguishing characteristics of this variety is its resistance to major diseases like leaf blast, bacterial blight races ($K_1$, $K_2$, $K_3$) and rice stripe virus disease. However, it showed susceptibility to major insect pests. Milled rice kernels are translucent with non glutinous endosperm and have 6.7% protein and 19.8% amylose contents. Milling recovery of head rice is 75.7%. The palatability of cooked rice is better than Keumobyeo. The milled rice yield of Junamjosaeng in local adaptability tests after harvest of the cash crop was $4.43\;tons\;ha^{-1}$. This cultivar is suitable for planting in the plain paddy fields of Honam and Yeonnam regions in Korea.

Gamifications offer utilities that may have potential to support convergence to become more engaged on their filed. This paper aims to design and implement gamification for the supporting of environment education based on the extended cooperation. We describe game mechanics, the system architecture, and its MDA model, finalizing with a small conclusion. We also discuss the implications of our work for the gamification that support the identified features and activate environment education. The result will be a framework for designing a gamification system that is suited for environment education. Ease, familiarity, relatedness, comfort, and usefulness were confirmed by the opinion polling. Our prototype has updated by reflecting their views and opinions.

This study was conducted to investigate the relationship between the socio-demographic factors and the Korean consumers palatability evaluation grades with Hanwoo sensory evaluation data from 2006 to 2008 by National Institute of Animal Science. The dichotomy logistic regression model and the multinomial logistic regression model are fitted with the independent variables such as the consumer living location, age, gender occupation, monthly income, beef cut and the the palatability grade as the categorical dependent variable and tenderness, 리avor and juiciness as the continuous dependent variable. Stepwise variable selection procedure is incorporated to find the final model and odds ratios are calculated to nd the associations between categories.

A new spray chrysanthemum(Dendranthema grandiflorum Ramat.) cultivar 'Yes Line' was originated from a cross between 'T22319' and 'SP02-037-13'. This cultivar was tested on the characteristics from 2004 to 2007 for the evaluation and selection including shading and retarding culture. The natural flowering time of 'Yes Line' is late October, but year-round production is possible by shading, lighting and retarding culture. This cultivar was single in flower type, with a color of red-purple(RHS 74C), with the flowers of 21.4 per stem. 'Yes Line' showed the vase life of 16.5 days in autumn season. The diameters of flower and flower center were 4.3 cm, 1.2 cm respectively. The days to flower under the short day treatment was 7.5 weeks and preference of consumers were high at 3.86 ranged up to 5.00. It has resistance to white rust and was possible to cultivate all-year-round.

‘Dongjanggun’ was developed at the Gyeongbuk Agricultural Research and Extension Services, Taegu in 2000. It was selected among the local varieties gathered korean native chinese chive from 1993 to 1996. It has longer and narrower leaves, stronger flavor than check variety ‘Greenbelt’. And also, contents of ascorbic acid in the leaves of ‘Dongjanggun’ was higher than the ‘Greenbelt’s. Number of tillers per plant was greater in ‘Dongjanggun’ than that in ‘Greenbelt’ during the winter in unheated plastic house. Its growth and regrowing velocity after cutting of top leaves were vigorous. Number of flowers and seeds per umbel were fewer in ‘Dongjanggun’ than in ‘Greenbelt’. Average yield was 6% higher than ‘Greenbelt’s during the thee years.

In this paper, we analyze the code tracking biases of single and double early-minus-late processing schemes which are widely used code tracking method for global navigation satellite systems. The code tracking bias which results from the distortion in symmetry of correlation values is arisen in the presence of multipath signals. To analyze them, two civil signals which are spreading signals modulated by binary phase shift keying and binary offset carrier are considered.

The study aims to compare our newest mathematics curriculum with Singapore's and analyse the differences of them. Because the levels of our mathematics education have been evaluated to be difficult to our students, we try to find that the evaluation is appropriate and there are other characteristics we have to notice carefully, and provide some implications for our mathematics curriculum. We mainly compared both mathematics curriculums focussed on the national documents of mathematics curriculum, and textbooks in the level of middle school. The results are following. Firstly, Singapore has three tracks based on students' abilities and there are three kinds of textbooks on the tracks. This is a different from our teaching on students level. Secondly, the introductions of our mathematics curriculum contents are not faster than Singapore's, but they have more concrete ranges of contents than us. Thirdly, the focus of Singapore's mathematics education lies on problem solving, and we can find some good examples of contents of textbook focussed on problem solving. Some mathematical concepts are introduced simply without any process of students discoveries or investigations, and the focus lies on the problem solving using the concepts. Fourthly, Singapore's mathematics textbooks are more emphasis on the internal connections than ours.
