Sesame (Sesamum indicum) is an important oil seed crop of Asia. Yields can be negatively impacted by various factors, including disease, particularly those caused by fungi which create problems in both production and storage. Foliar diseases of sesame such as Alternaria leaf blight may cause significant yield losses, with reductions in plant health and seed quality. The work reported here determined the incidence of Alternaria species infecting sesame seeds grown in the Punjab, Pakistan. A total of 428 Alternaria isolates were obtained from 105 seed samples and grouped into 36 distinct taxonomic groups based on growth pattern and morphological characters. Isolation frequency and relative density of surface sterilized and non-surface sterilized seeds showed that three isolates (A13, A47 and A215) were the most common morphological groups present. These isolates were further identified using sequencing of the Internal Transcribed Spacer (ITS) region of ribosomal DNA (rDNA) and the Alternaria major allergen gene (Alt a 1). Whilst ITS of rDNA did not resolve the isolates into Alternaria species, the Alt a 1 sequences exhibited > 99% homology with Alternaria alternata (KP123850.1) in GenBank accessions. The pathogenicity and virulence of these isolates of Alternaria alternata was confirmed in inoculations of sesame plants resulting in typical symptoms of leaf blight disease. This work confirms the identity of a major source of sesame leaf blight in Pakistan which will aid in formulating effective disease management strategies.

The genus of leafy green algae, Prasiola Meneghini, includes marine, terrestrial, and freshwater species. A total of 11 species and one variety have been identified in China, Korea, and Japan. In Korea, Prasiola formosana var. coreana has been reported in Muncheon, North Korea, while a different type of Prasiola species has been reported in South Korea. The South Korean species has been found growing along a small stream originating from Chodanggul Cave, a limestone cave in Samcheok, Gangwon Province. Here, we revised the morphological characteristics of the South Korean Prasiola species and analyzed plastid rbcL, psaB, and tufA genes to clarify its identity. Although the external and anatomical morphologies varied among individuals, our results were very similar to previous reports. Plastid three genes sequences of the South Korean specimens were identical to those of P. japonica collected from Japan as well as to published sequences of P. yunnanica from China. A short rbcL-3P sequence (196 bp) from P. formosana var. coreana, which was identified in the type specimen, was also identical to a sequence from P. japonica. These Prasiola species and variety from Korea, Japan, and China are all distributed in areas characterized by limestone bedrock. Based on morphological, phylogenetic, and distributional features, the South Korean Prasiola species is regarded herein as P. japonica. Here, we also propose to synonymize P. formosana var. coreana and P. yunnanica with P. japonica.

The purpose of this study is to identify characteristic of Swedish craft and modern design in especially furniture and interior design through the philosophy and humanitarian functionalism of Svenskt Tenn. The study completed through researching what the design paradigm of architecture and furniture design in those days was, and theoretically analyzing how this unique brand became a leading modern Swedish style in the European stream of functionalism design. Working upon this research, the study concludes the concept of the humanitarian functionalism design what Firma Svenskt Tenn wanted to realize through analyzing the aspects of form and material of Josef Frank' works who mainly contributed to form the Svenskt Tenn's unique design identity and comparing them to the other design examples of those days. The result are as follows: 1) Organic composition of space and elements, styles and functions, 2) Unique space composition of amalgamation, 3) Open space with abstract patterns, 4) Furniture shapes of displaying space environment, 5) Overcoming the limits of pragmatic functionalism based on rationalism.

The term "ya-o-ii" which is referred as a homosexual comics in Korea came from Japan and it became one of popular genres in both Japan and Korea's comics market. People create yo-o-ii with their own idea or borrow male characters from the pre-existed comics or animation and create a whole new story. Homosexual comics which is based on teenage readers deals with sex and focuses on homosexuality. For that reason it reflects social phenomenon than general material for comics. Before we focus on influence of homosexual comics on teenagers and social phenomenon, this study is for fundamental understanding on homosexual comics itself. In order to look into current state of homosexual comics, the survey was conducted at "Comic World" which is well known as the biggest offline comic event in Korea. This study analyzes range of age and awareness of readers of homosexual comics on the basis of the survey. Hopefully, this study helps better understand an influence of homosexual comics on teenage readers with problem of sex identity and contribute to the study of market segmentations of homosexual comics.

The objective of this study was to determine genetic variation of five Korean native chicken lines using 30 microsatellite (MS) markers, which were previously recommended by ISAG (International Society for Animal Genetics). The initial study indicated that two microsatellite markers, MCW0284 and LEI0192, were not amplified in these lines and excluded for further analysis. Twenty eight microsatellite markers were investigated in 83 birds from five Korean native chicken lines. The identified mean number of alleles was 4.57. Also, the expected, observed heterozygosity (He, Ho) and polymorphism information content (PIC) values were estimated in these markers and they ranged from 0.31~0.868, 0.145~0.699, and 0.268~0.847, respectively. The results were used for the discrimination of five chicken lines using genetic distance values and also neighbor-joining phylogenetic tree was constructed. Based on the He and PIC values, eighteen markers are enough for the discrimination of these Korean native chicken lines for the expected probability of identity values among genotypes of random individuals (PI), random half sibs ($PI_{half-sibs}$) and random sibs ($PI_{sibs}$). Taken together, these results will help the decision of conservation strategies and establishment of traceability system in this native chicken breed. Also, the use of ISAG-recommended microsatellite markers may indicate that the global comparison with other chicken breeds is possible.

Acording to the trend of highly increasing the public telephone, understanding consumer's design sensibility is based on designing consumer products reflecting user's identity and it comes out as a result of wore competitive products. For this study, consumer's desirous sensibility of the public telephone has been measured in checkable numbers. First of all, 35 sensible words are narrowed down from 168 whole sensible(adjective) words using the SD method. By this result, 7 scale form the SD method is applied to reserch on 10 current distributed products form 30 male and female university students. Element factor analysis is used to group the selected sensible words, duster analysis is used yo dassify them, and finally discriminant analysis is used to predict the relationship between design elements and the sensible words. As a result, words of human sensibility is known to divide into 3 factors; esthetics, functionality and safety, and the correlation of design factor is closely related with the the telephone's body, handset, dial board, dial button, ontrol button, color and material. To sum up, better public telephone design comes out from scientific and systematic consumer's desire analysis not designer's design technique.

The aim of this study is to provide practical guide for exterior design in apartment and to propose a device to improve the quality of residential environment by the color planning. Color is a language of context and used as a visual aid to recognize the objects and spaces in the world around us. In this sense, each color perception is unique to its own setting and not subject to any universal rules of thumbs, Therefore, when designing with color, each setting will demand its own specific set of rules. A balanced color scheme has to make the environment more pleasant for people to live in . Fro the exterior in housing the use of color has to be considered not just in its wider context of the architecture or surrounding but as an element of the life of the inhabitant. So it is considered on the type of people who will live in and visual condition of site. In this study , the objective model of systematic design process for environmental color planning is proposed on the basis of theroetical background and references investigated, By the existing thesis, resident's preference of the exterior color and foumular of composition in apartment was invastigated . In general theories, based on the theory Birren's color harmony for color coordination an design principles, a device of exterior color design in apartment was suggested by the course of reasonable design process. Color in environment plays many different roles. It integrates the architecture with the site. If color is use well, it can soften architecture that is too harsh, it can give a sense of identity to different part of site and improve a city's image. The environmental color is effective media to enhance the aesthetic value of architecture and environment.

On-line game business has emerged as the most lucrative entertainment industry, with over 4 million players in China, with more than 45% of the market dominated by Korean on-line games. While the interactive entertainment market continues to expand, with many new Korean on-line game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions (i.e., intention to play, brand-identity, word of mouth, flow, etc.) in this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' intention to play, social norms, word of mouth, flow, and the impacts of several other key game-related constructs. A conceptual framework is proposed and a simultaneous equation model is developed. This paper develops the exploratory LISREL model for identifying the factors affecting the players' intention to play for on-line games. Based on data collected from on-line questionnaire survey in China, the validity of the model has been tested and interesting conclusions have been developed concerning the relationships between the game-related constructs. It is hoped that this result might provide the useful guidelines for developing the successful on-line game contents. With better understanding of the players' behavioral intentions, Korean on-line game developers should be able to penetrate the China market with sustainable advantage over their competition.

The USIM(universal subscriber identity module)-unlock introducing in July 1, 2008 might be led to a significant change that mobile service provider's dominance is considerably dispersed to the handset manufacturer and distributor. Under USIM-unlock environment, mobile service provider, handset manufacturer, and distributor have to make their decisions on their handset distribution channel strategies: the closed distribution channel strategy or the open distribution channel strategy. The change of distribution channel strategy between members in distribution channel can be understood as a matter of strategy choice, and we have developed a theoretical model and analyzed how to make a decision for the member's optimal distribution strategy based on 3-person game model between members of mobile phone distribution channel, under both of '1 subscriber-1 handset' and '1 subscriber-multiple handset' assumptions. Under '1 subscriber-1 handset' assumption, the closed strategy controlled by mobile service provider is all players' optimal solution because the maximum size of the mobile phone market is limited by subscribers. But, as total expected profit by the handset and distribution subsides is a deficit, mobile service provider have to choose the open strategy and consider the conversion to MNO(mobile network operator). Under '1 subscriber-multiple handset' assumption, mobile service provider is trying to find the way how to lock-in its service and mobile phone and how to maximize ARPU(average revenue per unit), while handset manufacturer and distributor have to look for the way how to maximize the mobile phone market using their own marketing efforts, because it is expected that total mobile handset demand for the open market is bigger than demand for the closed market under '1 subscriber-multiple handset' assumption.

As the injunctive effect on the real estate gets announced in public once the seizure register gets exercised in terms of auction and the action of disposal by the real estate owner afterwards becomes nullified in the relationship with a seizure creditor or a successful bidder, the register performed by the cause of disposal action that cannot confront with the seizure or provisional seizure, becomes cancelled in virtue of a registration officer's office. Accordingly, in case of being a singular successor who relatively loses property in a relationship toward the successful bidder due to the injunctive effect of provisional seizure, the identity with building owner and land owner as the precondition of establishing legal superficies according to the custom must be decided based on the time of provisional seizure. The Supreme Court Decision 2010Da52140 delivered on October 18, 2012 has great significance from the fact that it has settled inconsistency in existing precedent cases with such purpose.
