This study was conducted to know how cold tolerance of rice varieties is inherited. Several crosses were made between cold tolerant varieties and susceptible varieties, and their progenies were morphologically and physiologically evaluated each characters at cold water and natural conditions. The segregation modes of leaf discoloration by cold treatment in F$_2$ generations are agreed to simple inheritance ratio of R3 : Sl in four crosses among total seven cross combinations. In F$_1$ and F$_2$ generations, tall one was dominance in culm and panicle length and less reduction in culm and panicle length by cold treatment was overdominance or partial dominance, while more number of panicles per plant was dominance and more increasing of panicle numbers by cold water irrigation was overdominance. Heritability and heterosis in most characters showed high values, and heterosis in remote crosses was especially larger under the cold water treatment condition compare with that under natural condition.

Recently, the use of SNS has been steadily increasing in the 40s and 50s in Korea. In order to increase the number of users in the global service brand, such as Instagram, facing the limit situation of new users, 40 ~ 50 new entrants are needed. However, 40 ~ 50s in Korea are not easily able to use these services because they have difficulties in these services. In this study, usability test is performed in terms of UX / UI about what is difficult for users in 40 ~ 50s to use in instagram, and what is the barriers to entry compared to domestic service The results are as follows. First, when localizing a global service, it is easy to understand, not a simple translation, and proper labeling should be considered. Second, major and frequently used functions should be considered to be intuitive to simplify the depth. Third, the design should be improved to increase the recognition rate of icons in terms of GUI. If possible, the combination of text and icons provided good results.

In this study, we attempted to find alternative materials to rice bran (Japonica in Korea) such as rice bran pellet (Indica in Pakistan), corn distillers dried grains with solubles, sesame oil meal, and kapok meal for bottle cultivation of Pleurotus eryngii. Among all treatments, the total carbon content of the mixed substrate was the highest in T1 and the total nitrogen content was the highest in T4. The C/N ratio of T2 was comparable to that of the control and was higher than that of other treatments. The diameter of the pileus was the largest in T1 and T2, and the length of the stipe was the largest in T1 and T2. The yield and bio-efficiency of the fruit body were higher in T2 than in the other treatments, and were similar to that of the control plot. Therefore, the findings of our study suggest that rice bran pellet (Indica in Pakistan) could be a suitable alternative to rice bran (Japonica in Korea) for the cultivation of P. eryngii.

Post-Modern Multiculturalism is spreading in many ways and other cultural interest has led to the Latin American culture, which has steadily appeared as the main fashion concept of the international collection. Frida Kahlo(1907-1954), a representative of Latin American culture and a Mexican female surrealistic painter, who gives us some inspiration for contemporary fashion design. The purpose of this study is to have a correct understanding of and research on Latin American culture and to expand the expression of fashion design. In the process, this article examines the costume of Mexico belong to the Indio culture which had been regarded as the Other for a long time and understands Frida Kahlo's fashion style: Tehuanas costume and her masculine style. The Tehuanas costume is a traditional style of the city, Tehuantepec, located in the southeast of Mexico, which is characterized by colorful floral patterns and a long skirt. Three fashion concepts were derived from her fashion style: tradition & modern, love & farewell, and masculine & feminine. The scope of this study investigates the Haute Couture and the Pret-a-porter women's wear collections and photos from 1998 to 2010 in Europe, USA and South America. From classifying the collected photos into each concept, three styles such as ethnic, romantic and androgynous style were derived. These fashion styles were analyzed through the formative elements of dress, color, silhouette, pattern, material and clothing construction in order to figure out how costumes of other cultures influenced on contemporary fashion. As a design inspiration, Frida Kahlo extends her influence into innerwear, accessories and hairstyles, as well as women's wear. These inspirations emerge steadily from the past and far into the future as an expression of a fashion design concept.

For the study on the Latin American culture reflected in fashion designs since 2000, the applications of Latin American culture shown in the four major collections from 2000 S/S to 2005 F/W (110 pieces) and some African designers' collections (157 pieces) have been analyzed and compared in three categories - forms, patterns and accessories. First, in the formal application of traditional clothes, the traditional elements of Indio culture are utilized in both the four major collections (76.8%) and the Latin American designers' collection (77.1%). Quechquemitl, the traditional Indio clothes are utilized in various forms in the four major collections, while the Latin American designers adopt various forms of traditional clothes, such as quechquemitl, camisa and pollera. Second, in the textile design, the patterns from Indio's traditional textile design are utilized in both the four major collections (68.7%) and the Latin American designers's collections (5.6%). The remarkable difference between the Latin American designers and the western designers is that the former like to mix the simple and primitive Indio culture with the colorful Iberian culture, and to utilize various patterns of feather, which is an important symbol in the traditional culture, expressing tradition in the modern touch. On the other hand, the western designers change the primitive and handcraft feel of Indio patterns into colorful ones, or mix the colorful Spanish-style flower patterns with primitive and passionate feel. Third, simple and handcraft feel of Indio accessories are utilized in modern fashion in both the four major collections and the Latin American designers' collections. The most remarkable difference between the two group of designers' collections is that various feather patterns are used in Latin American designers' collection, while the accessories reminding of relics of Maya and Inca are widely used in the four major collections.

This study was conducted to know how cold tolerance of rice is inherited. Several crosses were made between cold tolerant and susceptible varieties, and their progenies were evaluated for days to heading, spikelet number per panicle and spikelet fertility under both cold water and natural conditions. In F$_1$ and F$_2$ generations, earlier heading, more number of spikelet per panicle and higher spikelet fertility under the cold condition were dominance, and less delay or reduction in heading days and spikelets per panicle by cold treatment were over dominance or partial dominance, while less reduction in spikelet fertility by cold-water irrigation was complete dominance. Heritability in most characters by cold treatment was high and there was less difference of heritabilities in heading days and spikelets per panicle between cold treatment and natural conditions, while there was much difference of heritability in spikelet fertility between two conditions. Heterosis in spikelet fertility was considerably high, while those in heading days and spikelets per panicle were relatively low. Heterosis in remote crosses was especially larger under the cold-water treatment condition compare with that under natural condition.

High density (HD) grains is associated with seedling vigor. Studies were conducted on the relationship of different grain densities and vascular bundle(VB) development and seedling growth. IR58 (indica type) and Unbong 7 (japonica type) were used in this experiment. HD grains had more and bigger VB in the leaf blade and sheath than poor density grain at seedling stage. IR58 had more large VB at the leaf compared with Unbong 7. Higher development of VB in seedling of HD grains can increase transport of assimilate and growth rate. Plant height, leaf number, root growth and dry weight increased with increasing grain density from poor to high. The total area of large VB in the leaf blade and sheath was highly correlated with the dry weight. Higher number and larger area of VB and dry weight can be obtained by using HD grains and these initial advantages can contribute to high yield potential.

Adquate friction resistance is needed to prevent pavement slipperiness and to allow vehicles to stop in a reasonable distance. Performance of the aggregates is reduced over time by wear and polishing as a consequence of vehicular traffic. In this research, the objective was to develop a laboratory method to test Indiana gravel aggregates to predict field performance, and determine causes for the range of values amang gravel aggregates. The assessment of gravel sources was primarily on the basis of individual rock types and those proportions comprising the gravel. Polish and friction values were determined in the laboratory with the British Wheel and Pendulum. The gravels of this study were composed primarily of carbonate aggregates that showed considerable variability in polishing thresholds. Igneous and metamorphic constituents polished to a lesser degree and are expected to improve overall aggregate performance. Estimates of the IFV (Initial Friction Value) and PV (Polished Value) for crushed gravel samples can be made based on the percentage of rock types present in the sample. A weighted average is used to make this calculation.

In this paper, we propose and describe the system to visualize the story of contents such as movies and novels. Character-net is applied as story model in order to visualize story. However, it is the form to be accumulated for total movie story, though it can depict the relationship between characters. We have developed the system that analyzes and shows the variation of Character-net and characters' tendency in order to represent story variation depending on movie progression. This system is composed by two windows that can play and analyze sequential Character-nets by time, and can analyze time variant graph of characters' degree centrality. First window has a function that supports to find important story points like the scenes that main characters appear or meet firstly. Second window supports a function that track each character's tendency or a variation of his tendency through analyzing in-degree graph and out-degree. This paper describes the proposed system and discusses additional requirements.

Interest in the development of urban trails is growing in South Korea. River front trails have been developed in Seoul, Daegu and other major cities. Such trails, and the corridors in which they are developed, often provide a myriad of benefits to the community, including open space, exercise, and stress release. This trend mirrors development patterns found in the United States and European nations. This study examined differences in trail users perceptions of trail attributes, activity participation, willingness to pay for trail access, and perceptions of trail benefits between trail users in the United States and those in South Korea. Perceptions of trail users at three trail sites in the metropolitan area of Daegu were examined, and then were compared to results reported in several studies conducted in the U. S. While this research was exploratory, it did uncover many interesting differences in perceptions of trail attributes between trail users in the two countries. This information may provide insight into the development of greenway systems in South Korea.
