This study aimed to characterize the mycelial morphologies of Hericium erinaceus isolates, including 18 wild-type collections and cultivatable species 'Noru 1' and 'Noru 2', in Korea. The morphological characteristics were used to classify the species based on aerial or branched mycelia and their brownish or whitish colors when grown on potato dextrose agar. Of the wild-type collections, the isolates KFRI 509, KFRI 1091, KFRI 1093, and KFRI 1623 showed faster mycelial growth than the cultivars 'Noru 1' and 'Noru 2'. Moreover, 60% ethanol extracts of the fruiting body of the mushroom showed the highest phenol content and DPPH and ABTS radical scavenging activity. The DPPH and ABTS radical scavenging activities of KFRI 507, KFRI 508, KFRI 842, and KFRI 1623 were 10-60% higher than those of 'Noru 1' and 'Noru 2', depending on the extract concentrations. Thus, results suggest that these wild-type collections could be useful for breeding genetic sources or processed food materials with high antioxidant activity.

The Knowledge and information are rapidly built through networks; and, through this, epochal changes and developments are reoccurring in diverse societal economic cultural ways. Especially, digital-education emerging together with educational environment changes is taking its place as an educational system which will be able to replace traditional education methods by overcoming the limitations of time and space held by present education methods. The role of GUI(Graphic User Interface) design, which adds user cognitive power and convenience as a method of purveying innumerous information, is growing. Consequently in this research, through the analysis of educational contents utilized in public organizations, research is performed regarding an educational content design for a more effective education of learners.

With the beginning of foreign workers' immigration since 1990, Korea has faced multi-cultural society. At the same time, the number of female marriage immigrants have constantly increased. But the social services for immigrants are not yet prepared. According to the research on the actual condition of immigrants' culture enjoyment, which was done by Ministry of Culture, Sports and Tourism of Korea, the most preferable leisure activity of immigrants is 'sightseeing'. So this study focused on improvement of web contents of tourism information to satisfy the information needs of immigrants. Concretely, this study analysed the present condition of the existing tourism web contents, and analysed deeply the web site 'Tourism Busan' for special reference. Especially this study tried to analyse VOD images among web contents of 'Tourism Busan', and provided concrete improvement plan for that. And also this study processed interview with marriage immigrants to provide web site evaluation at the level of immigrants' eyes. As a result of evaluation, immigrants was the most dissatisfied with 'contents quality', and showed lower dissatisfaction at 'service quality', 'interface quality' factors.

In this research the current situations of libraries of 119 rural elementary schools are examined. These schools are the applicants for the 'Campaign for Libraries for Rural Schools' sponsored by Chosun Ilbo in 2009. Through the content analysis of their applications, the factors of facilities, collection, and environment are described. One the surface, most of these applicants look fine with the current size of collection and annual additions. They, however, commonly document the extremely poor conditions of facilities, unbalanced and low quality of books, lack of financial support, and cultural isolation. Even though they are not the typical rural school libraries, it seems urgent to improve their inferior conditions that any library statistics never shows in numbers. In this research, it is considered significant to make local governments and offices of education change their attitude toward rural school libraries and increase their financial support to them. The suggestions are as follows: First, let them know that school library policies concern the voters in communities; Second, use the visibility of various authoritative library assessments and awards; Third, strengthen the qualitative aspect of library evaluations.

The government is supporting the law not to be uncomfortable in all departments of some sports and cultural activities for the handicapped, making the Welfare Law for People with Disability(Article 25) in Korea. Moreover web sites which are places of business more than 300 employees including other public organizations are making it mandatory to observe web accessibility for the handicapped. This study analyzed in statistical aspects to investigate systematically how professional sports clubs observe the accessibility of web site to some degree. As a result, it turned out that the compliance record on the items of the providing of text alternatives(44.92%) for non-text content and the keyboard accessible(46.79%) was low. However, by and large we are able to recognize that the compliance record of the web site is on an increasing trend with the course of time.

The compressive strength of PEG along processing concentration and solvent is willing to be measured and proper processing condition for exhibition and storage is also willing to be measured by comparing with dimensional stability. In the advanced research of setting PEG-preprocessing concentration & solvent for freeze drying of waterlogged archaeological wood of high water content, vacuum freeze drying showed the highest dimension stability after 40% PEG-preprocessing of aqueous solution. In this study, the compressive strength increased in proportion of processing concentration and water showed the relatively-higher compressive strength than t-butanol regarding solvent. Especially, it showed that there is no big strength difference between PEG 40% and PEG 50% in aqueous solution by 6.6%(16kgf/$cm^2$). According to the above results, it was recognized that it is most effective to implement freeze drying after 40% PEG-preprocessing when want to dimensional stability and compressive strength simultaneously.

This study focuses on reinforcement agents for wall damage, such as cracks, breakage, or delamination, for mural paintings from the Payathonzu temple. Experiments were conducted with filling and grouting agents based on the reinforcing method. In the filling reinforcement experiment, different mixing ratios of lime to sand, and additives (jaggery, seaweed glue, and Primal SF-016) were used. In the grouting reinforcement experiment, the mixing ratio of lime and pozzolan was the same, and the additive types were identical to the filling reinforcement experiment. The filling reinforcement experiment showed that there were fewer physical changes such as contraction, with a greater mixing ratio of lime to sand, however, the compressive strength decreased as the mixing ratio increased. With additives, the change in volume of agent decreased and the compressive strength increased, which was especially prominent for jaggery and Primal SF-016. The grouting reinforcement experiment showed that there was a remarkable contraction with an increased amount of moisture that originates from the characteristic of grouting agents that requires flowability. With additives, the water content of the agent decreased, whereas the compressive strength and adhesion increased. Among the additives, Primal SF-016 exhibited the highest compressive strength, and seaweed glue exhibited the most considerable viscosity and adhesion. The study results showed that the characteristics of reinforcement agents vary according to the mixing ratio and additives of the filling and grouting agents. Therefore, it is necessary to selectively apply the mixing ratio and additives for different reinforcement agents considering the wall damage for conservation treatments.

Tarak is our own traditional fermented milk made through lactic acid fermentation by using makgeolli as inoculum for milk or using already made tarak as inoculum but it is hardly known to people as its related studies are also insufficient. Accordingly, the purpose of this study was to manufacture jelly by using tarak and analyze its quality characteristics for the diversification of consumption promotion and demand of traditional fermented milk tarak. Tarak jelly that was made according to the percentage of adding tarak showed a tendency that the content of crue protein, crude fat and crude ash except for moisture water meaningfully increased as the amount of tarak added increased (P<0.05). In the case of pH, it declines as the amount of tarak added was high. The chromaticity measurement result of tarak jelly was 54.32 in the case of control group for L, and it increased as the amount of tarak added increased. In the case of a, it decreased as tarak was added, whereas b meaningfully increased. There was meaningful difference between samples in the case of chewiness, fracturability and adhesiveness (p<0.05). The sensory test result showed that there was meaningful difference between samples in their appearance and taste but there was no meaningful difference in the case of overall preference, scent and texture.
