본 연구에서는 리그경기의 요구조건을 분석한 후, 리그경기 일정계획을 위한 모형을 개발하였다. 개발된 모형을 마이크로컴퓨터를 통해 이용자가 사용하기에 간편하도록 구현화했다. 본 연구에서 개발된 리그경기 일정계획 시스템은 각종 리그경기, 특히 연고지를 가진 상업적인 리그경기의 일정계획에 이용될 수 있다. 참가하는 팀들의 요구조건을 적극 반영할 수 있도록 민감도 분석기능을 추가시켰다. 개발된 시스템을 이용할 경우 현재 수작업으로 수행중인 리그경기 일정계획에 많은 도움이 있을 것으로 사료된다. 개발된 시스템에서는 각팀의 이동거리가 비교적 우선순위가 낮은 요구조건으로 분석되었으며 이동거리르 최소화시키는 방법으로 연속 홈경기와 방문경기를 적정수준 이하로 유지시키면서 각팀의 이동거리를 합한 총거리를 최소화하는 방법을 사용했으나 각팀의 실제적인 이동거리가 Critical한 경우에는 Multi-Objective Traveling Salesman기법을 사용하여 향후에 해결이 가능할 것으로 여겨진다.

The purpose of this study is to analyze the problems facing the youth soccer league(i-league) and present their development directions. The study method used focus group interviews. The results of the study are summarized into three: First, promotion and regional league operation were highlighted as problems of i-League and the solution was the unification system of the Korean Olympic Committee(KOC) and the Korea Football Association(KFA), and the operation of each region by itself. Second, issues resulting from the integration of youth club league and i-league were revealed as level differences by teams and leak of the motivation for winning. Operation of the elevating system was proposed as a solution, and such as fare play team award, voluntary activity team award will derive important virtues for youth. Third, KOC and KFA need additional support for various environments and administrative areas such as facility security, training for leaders and officials, and registration of players.

고중량, 부식 등의 문제를 안고 있는 목재/강재 리그매트를 대체할 수 있는 고강도 경량 고내구성 특성을 갖는 복합소재 리그매트를 전통 목재 연결방식의 결구시스템을 응용한 새로운 개념의 스냅핏 방식으로 개발하였다. 본 논문에서는 기존에 개발한 리그매트와 이를 개선한 개선형 리그매트의 스냅핏(snap-fit) 연결부의 안전성을 검증하기 위해 연결부 착탈 거동에 대한 해석 및 구조성능 시험을 실시하였고, 그 결과를 비교 분석하여 스냅핏 연결부의 긍정적인 효과를 입증하였다.

In the current so-called age of emotion marketing, the independent form of handwriting of calligraphy is being revitalized in various fields such as advertising, book designs, film titles, posters, packages, BI, and even fashion. Thus centered on Gyeyang-gu at the city of Incheon, 100 outdoors signs that used calligraphy were chosen and we researched a reform plan that could revitalize calligraphy in outdoor signs by classifying them according to current conditions of the use of calligraphy, actual conditions of practical use, expression tools, and analyzing the use of colors. The result was trial requests not only from the formalities industry, but also the financial sector, public corporations, and several other businesses, but in order to provide not only for franchise brand logotypes manufactured by expensive experts, but also provide production of high-quality calligraphy for low costs for small private enterprises, the development of a diverse calligraphy education program, centered on the regional society, will be needed. In the midst of globalization, in order to advertise the beauty of Korean alphabet and to create our own unique street culture, a variety of tools and tactile expressions are demanded, in the future the research on the calligraphy of outdoor signs must be revitalized.

This study used data of soccer match 5170 games from 1950 to 2008 in five European football professional leagues. We compared average of SGPG (scored goal per game) in each two and three points of win. And we compared average of SGPG in each leagues. In order to predict PtsG (points per game), we executed regression analysis using SGPG and LGPG (lossed goal per game). Finally, We applied regression analysis to a K-league.

Sesame (Sesamum indicum L.) is an ancient oilseed crop, which is usually cultivated for its seeds. Sesame breeding aims to achieve high seed yield and quality, along with resistance to biotic or abiotic stresses. It is estimated that sesame is originated from Asia or Africa continent. In this study, we characterized 10 agronomic traits and evaluated lignan contents in 165 sesame germplasm originated from Asia or Africa, to select high-yield or high-lignan content accessions. Sesame germplasm showed diverse phenotypes and highly variable lignan contents (sesamin: 0.5-12.6 mg/g, sesamolin: 0.1-3.5 mg/g, lignan: 1.1-16.1 mg/g). Based on originated continent, there are significant difference in agronomic traits, but no in lignan content. Correlation analysis revealed that yield-related agronomic traits were negatively related with lignan contents. Also, PCA analysis showed that most agronomic traits and lignan contents were principal components explaining diversity of whole sesame germplasm. Sesame germplasm was clustered into three groups based on agronomic traits and lignan contents. Finally, we selected high-yield (IT29416, IT167042, K276848, K276849) and high-lignan candidate accessions (IT169254, IT170031, IT169250, IT154876, IT170034), respectively. These accessions are expected to be valuable resources for breeding of high-yield and high-lignan contents functional cultivars.

Recently, calligraphy has become popular because people focused on emotion. The strokes, dots, swoops, cracks and shading are the calligraphy factors for expressing various emotions such as joy, anger, sorrow, and delight. However, the emotion which is expressed by cracks and shading can be destroyed in the digital work when the calligraphy is used for a variety sizes of prints. Professionals work with high-resolution images which are obtained through the scanner, however normal users should work with low-resolution images taken with the smart phone for calligraphy image editing. We propose a raster image scaling method focused on calligraphy that maintains the emotion with cracks and shading, when normal users use the low-resolution calligraphy images in the digital work. The method recolors aliasing boundary of enlarged rasterized image. When recolored by our method, our method decreases aliasing by using the image gradient method, vivify calligraphy images, and maintains the emotion in cracks and shading by using the alpha value.
