This study was conducted in order to better understand the local and specialty foods of the Yeong-ju region. This study provides basic data for new menu development and commercialization. The results of 384 surveys, which were conducted to determine traditional rice cake production methods and their traits, were analyzed. Samgyetang was ranked top in the survey on recognition, public interest, and frequency of the local foods. Dakjuk was ranked second, followed by Baechujeon and Bopguk, in order. The levels of recognition and preference of specialty foods were in the order of hasuo, peach, apple, and meat. Among the answers in the survey on the popularization and commercialization of local foods, changing of the cooking style for younger generations' taste was considered to be the most important. Holding events to promote regional specialty foods and initiate the public to traditional cooking styles were listed sequentially by importance. The survey results show that promotion of local foods through education, and as well as incorporation of new ingredients are both highly effective ways to commercialize local foods for tourism. The results also indicate that taste, nutrition, and appearance of food should be considered in order to improve quality.

The phylogenetic diversity of the bacteria in hot composting samples collected from three spatial locations was investigated by molecular tools in order to determine the influence of gradient effect on bacterial communities during the thermophilic phase of composting swine manure with rice straw. Total microbial DNA was extracted and bacterial near full-length 16S rRNA genes were subsequently amplified, cloned, restriction fragment length polymorphism-screened and sequenced. The superstratum sample had the highest microbial diversity among the three samples which was possibly related to the surrounding conditions of the sample resulting from the location. The results showed that the sequences related to Bacillus sp. were most common in the composts. In superstratum sample, 45 clones (33%) and 36 clones (27%) were affiliated with the Bacillus sp. and Clostridium sp., respectively; 74 clones (58%) were affiliated with the Clostridium sp. in the middle-level sample; 52 clones (40%) and 29 clones (23%) were affiliated with the Clostridium sp. and Bacillus sp. in substrate sample, respectively. It indicated that the microbial diversity and community in the samples were different for each sampling site, and different locations of the same pile often contained distinct and different microbial communities.

The development in information technology resulted in an interest for lifelong education, which caused a rapid growth in the educational web based e-Iearning industry. The spread of e-Iearning industries and educational facilities emphasized the need for educational contents with the purpose of online lecturing along with the rapid development of contents production technology. Flash contents provide multimedia, animation, and etc. with diverse and visual expressions, so the complicated interactions with the learner can be easily materialized. The advantage of having a high quality, user-centered interface is that it provides a trigger of interest and arousal of concentration for the user, but it is difficult for teachers to directly create or manipulate educational flash animation contents. This paper is written to technologically methodize the automation of educational programs that the teachers wish to make by reusing the educational flash animation contents.

This study started from recognizing the problem that neither the identity nor the role of records managers is clarified enough. Therefore, this study identifies the function of the records managers and how it should be carried. The method of functional analysis was used to collect information, and then the AHP method to analyze te core functions of the records managers. As a result, core functions were identified as follows: records management policy making, education, production control, records schedule management, collecting, transferring, description, appraisal, de-accessioning, records center management, disclosure, perusal service, and records management system. Therefore, this study presents that identity and role of the records managers as well as the priorities of the job.

Objectives: Electronic cigarettes are battery powered devices that convert a nicotine-containing liquid into an inhalable vapor. The device aerosolizes nicotine so that it is readily entrained into the respiratory tract, from where it enters the bloodstream. Information on the safety of E-cigarettes is required. Methods: Seventeen articles on studies analyzing toxic substances in the liquid and gas phases of electronic cigarettes were reviewed. Results: Tobacco-specific nitrosamines, bis(2-ethylhexyl) phthalate, formaldehyde and acetaldehyde, known to be carcinogenic agents in humans or animals, were detected in the liquid and gas phases. In addition, diethyl phthalate, acetone, ethanol, cresol, xylene, propylene, styrene, triethylene glycol, tetraethylene glycol, pentaethylene glycol cis-3-hexen-1-ol, methyl cinnamate and undecane were identified in the liquid and gas phases of E-cigarettes. Propylene glycol, glycerin, 1-methoxy-2-propanol, 1-hydroxy-2- propanone, acetic acid, 1-menthone, 2,3-butanediol, menthol, carvone, maple lactone, benzyl alcohol, 2-methyl-2-pentanoic acid, ethyl mantel, ethyl cinnamate, myosamine, benzoic acid, 2,3-bipyridine, cotinine, hexadecanoic acid, and 1'1-oxybis-2-propanol were detected in the vapors of E-cigarettes. Conclusion: The hazardous compounds identified in the liquid and gas phases of E-cigarettes should be controlled for the lowest concentrations in the raw materials and production procedures.

The rural living improvement in Japan operates in considerations of socio-eoonomic circumstances of rural community as in Korea. After 1945 the program emphasized the improvement of living conditions such as poverty alienation improvement of house and toilet nutrition after war, From 1955, health programs including better cooking and nutrition, house modification and improved living conditions corresponding to the goal of the developed country were carried out. In 1965. the goal of the rural home economics was focused on the harmonized production and living, improvement of the levels of rural living, health and building rural community. From 1975, the goals of the program were to organize the farming in the better ways and improvement of rural women's role. In 1985, making agreeable living conditions was emphasized under the goal of vital rural society. From the period of Heysey(1989${\sim}$), for better living of rural people the government is emphasizing the programs including farm labor management, utilization of farm products, farm management and rural environments. Recognizing the important influencing resources of agents in extension services, on the job and education was implemented step by step from basic to planning to upgrade competencies. The government is trying to construct better with infrastructures, encouraging direct selling the value-added processed food from local farm products with rural people's real name and other countryside resources. Major programs in the 21st centuries are building better rural society with men and women together and considering elders as well as new farmers.

Surveys for visitor's awareness and on-the-spot investigations at Odae Mountain National Park were conducted for activation of nature interpretation. As a result, many problems on observation trails as the object of the nature interpretation were identified. The nature interpretation is not functioning fully for the side of environmental education. The situation and problems of nature interpretation were analyzed in depth based on the survey of the visitors. In order to improve roles of the nature observation trails and solve the present problems immediately, suggestions are as the followings. I) Road resurfacing and space development needed to solve the problems of existing nature observation trail. 2) Public relations for nature observation trail and production of signboards promoting visitor's interest. 3) Development of nature observation trail used only for nature interpretation 4) Development of adequate Korean interpretation program based on systematic nature interpretation models from other developed countries

For a large scaled optimization based on response surface methods, an efficient quadratic approximation method is presented in the context of the trust region model management strategy. If the number of design variables is η, the proposed method requires only 2η+1 design points for one approximation, which are a center point and tow additional axial points within a systematically adjusted trust region. These design points are used to uniquely determine the main effect terms such as the linear and quadratic regression coefficients. A quasi-Newton formula then uses these linear and quadratic coefficients to progressively update the two-factor interaction effect terms as the sequential approximate optimization progresses. In order to show the numerical performance of the proposed method, a typical unconstrained optimization problem and two dynamic response optimization problems with multiple objective are solved. Finally, their optimization results compared with those of the central composite designs (CCD) or the over-determined D-optimality criterion show that the proposed method gives more efficient results than others.

Laccase (EC 1.10.3.2) is a small group of enzymes that catalyze the oxidation of a broad range of phenolic compounds including hazardous and recalcitrant pollutants in the environment. This study attempted to develop an efficient system for production of a recombinant laccase by chloroplast genetic transformation of tobacco. Chloroplast transformation vector was constructed and introduced into the tobacco chloroplast genome using particle bombardment. Chloroplast-transformed plants were subsequently regenerated. PCR and southern blot analyses confirmed stable integration of the laccase gene into the chloroplast genome. Northern blot analysis revealed that mRNA of the laccase gene was highly expressed in chloroplast-transformed plants.
