Sixty medicinal and food plants native to Korea were mainly selected with old traditional habit and antioxidant activity was investigated. The 80% EtOH extracts of sixty medicinal and food plants were screened for antioxidant activity. Antioxidant activity was measured by the TBA (Thiobarbituric acid), DPPH (1, 1-Diphenyl-2-picrylhydrazyl), SOD (superoxide dismutase) which was evaluated by the nitro blue tetrazolium(NBT) reduction method. Among sixty plants, black Glycine max(87. 3%) and Solanum nigrum (80.6%) exhibited the highest antioxidant activity by TBA and DPPH methods, respectively. Also, 10 species extracts including black Glycine max showed the high activity value in these two methods. The SOD characteristics on black Glycine max seed extracts which showed the highest SOD activity (53.5%) exhibited four major SODs; two Cu/ZnSODs and two FeSODs. However, Adenophaora vertidllata which showed lowest SOD value (10.4%) had only Cu/Zn SOD. No varietal differences in the high SOD value were detected in the Cu/Zn SOD isozyme patterns.

Young adults are not met adequately by the traditional public library service patterns, being compared for children and adults even though they belong to the main user groups in number. Adolescence is a unique developmental stage distinct from childhood and adulthood and it is fair to say that today's young adults face complex present and confusing future. Projects are made to address the full spectrum of the young adults needs and the important role of public libraries as partners to solve the social youth problems in the USA. The library professional organizations issued young adult service guidelines, recommendations, and manuals to assist public libraries to offer good service programs to young adults. This paper provides the basics of young adult services in the public libraries to help Korean public libraries acknowledge the importance of young adult services and improve the framework of young adult services.

The purpose of this study was to investigate the dweller's housing needs through the connection between dwellers' living pattern and space usage. The objectives were (1) to examine how to eat and cook in the eating and cooking spaces, (2) to examine how to alter the original housing, (3) to research the dwellers' housing needs for the eating and cooking spaces, and the changing process of dwellers' housing needs, and (4) to classify the type of eating and cooking spcaces. The results of this study were (1) there were changed in eating pattern of space usage according to the season. The eating activities were a Korean living pattern : sitting on the floor and eating at the BAB SANG. (2) There was a difference in the pattern of space usage and the activity for main cooking and KIM CHI. (3) AN BANG (eating space for winter) as well as MARU (eating space for summer) has changed to a larger space. (4) By the changing of living patterns, BU AUK (a main cooking space ) has showed a various alternations: function, dimension of space, facilities, floor materials and floor level. (5) The dwellers' housing needs for eating space were a multipurpose room, and a dining kitchen of western living pattern (using a dining table and chairs) with the present changing life styles. (6) The dwellers' housing needs for cooking space were a multipurpose room of working area, a seperation of heating area, a western living pattern, a plan of flat fllor level and a dining kitchen. (7) BU AUK of eating and cooking spaces was classified into 4 types: a traditional type, a mixing type, a modernized type, and a western type.

This research investigated the needs analysis on consumers of fine dust masks to effectively develop a design prototype. Data were collected through focus group interviews on 32 individuals who have used fine dust masks. As a result, there is a new demand by consumers for technology based design changes that better fit the nose and face. Consumers preferred the smell and feel of traditional Korean paper. Young adults expressed the importance of masks that can be used for protection as well as fashion. The prototype improved the drawbacks of existing models using an origami-inspired design in a variety of colors, patterns and in sizes that are customized to fit the wearer. The proposed prototype is made of Dak felt fibers and jersey materials. It is characterized by downward-facing ear bands made of polyurethane to improve the fit around the ears and chin to more effectively block incoming air. The mask is foldable and has a crease that goes along the chin to increase the amount of enclosed space against the face making it easier to breathe compared to existing mask designs.

Late blight, caused by the hemibiotrophic oomycete pathogen Phytophthora infestans, has been the most important disease limiting potato production worldwide. P. infestans undergo major population shifts in agricultural systems via the successive emergence and migration of asexual lineages. The phenotypic and genotypic bases of these selective sweeps are largely unknown but management strategies need to adapt to reflect the changing pathogen population. Here, we used molecular markers to divide the 86 South Korea isolates into six clonal lineages: KR_1_A1, KR_2_A2, SIB-1, US-11, SIB-1 like, and KR-2 like. We documented the emergence of a new lineage, termed SIB-1 like, and KR-2 like, and their rapid replacement of other lineages to exceed 35% of the pathogen population across South Korea. Genome analyses of the Korean P. infestans populations revealed extensive genetic polymorphism, particularly in effector genes. Importantly, SIB-1 like isolates carry an intact Avr8 effector gene that triggers resistance in potato carrying the corresponding R immune receptor gene R8 cloned from Solarium demissum. These findings point toward a strategy for deploying genetic resistance to mitigate the impact of the SIB-1 like lineage and illustrate how pathogen population monitoring, combined with genome analysis, informs the management of devastating disease epidemics. Further study is being done on pathogenicity of the SIB-1 like isolates on cultivated potatoes and changes in expression patterns of disease effector genes within the SIB-1 like isolates

Interest in environmental pollution is increasing all over the world, and technology development to solve it is actively carried out. In areas where heat is used, especially, combustion is causing countless pollutants in the air environment. Combustion catalyst is a technology that reduces NOx and CO by lowering combustion temperature and enabling complete combustion. Traditional combustion catalysts are expensive and complex in the synthesis process using precious metal catalyst. In this study, hexaaluminate, a high-temperature combustion catalyst, was manufactured using urea, and the properties were investigated according to the synthesis time. The combustion performance and characteristics were evaluated using this catalyst. As the temperature increased, the changing methane conversion rate was shown in two patterns. The conversion rates for 1 hour, 9 hours, and 12 hours were similar, while the conversion rates for 3 hours and 6 hours showed similar patterns. Methane combustion performance increased rapidly as the synthesis time increased from 6 hours to 9 hours, whereas the temperature at T50 was approximately 745 ℃. The performance of the synthesized combustion catalyst for 9 hours was optimum as the NOx emission of this combustion catalyst was not present and the maximum emission of CO was 72 ppm.

The purpose of this study is to improve the usefulness of photogrammetry in the field of cultural heritage recording concentrated on laser scanning. Two measurement methods(laser scanning, photogrammetry) were compared in terms of accuracy and reality for the Rock-carved Standing Buddha in Singyeong-ri, Hongseong. With regard to accuracy, the distances of major points by both shape information and between the two shape information were compared. Only a deviation of about 1mm was found in the distance measurement of the major points by both shape information. In particular, the average distance between two shape information identified through aligning was only about 0.01mm. Also, the absolute deviation within about 2mm accounted for 70% of the total, and the absolute deviation within about 3.5mm was found to be 95.4% of the total. These values showed very high similarity between laser scanning and photogrammetry-based shape information. In respect of reality, the carved depth, texture, and patterns were compared. As a result of comparing four cross-sectional shapes, only slight differences were found in the shape information of both measurement techniques and similar shapes were identified. The overall texture of both shape information was also similar. However, the detailed shape based on the photogrammetry with decimation is realized with a smoother texture than the original and laser scanning. In particular, Photogrammetry also realistically expressed the various ornaments carved in the Rock-carved Buddha and the patterns with shallow depths were comparatively detailed.

This study interpreted the logical validity of the landscape restoration and maintenance patterns of Changgyeonggung Palace, where modern landscapes coexist. The results of the study are as follows; First, the changes in the landscape restoration and maintenance attitude concerning the Changgyeonggung management organization were identified. With the establishment of the Office of the Imperial Garden, an imperial property was nationalized. The Cultural Heritage Managing Department was opened in 1961, and Changgyeonggung Palace were preserved as designated as historical sites in 1963. An environmental purification was implemented by the Changgyeonggung Office as a follow-up measure for restoration in 1983. As the Cultural Heritage Administration promoted in 1999 and the Royal Palaces and Tombs Center was established in 2019, the palace has been managed professionally as a palace landscape to provide a viewing environment. Second, In the 'Purification Period of Changgyeongwon(1954~1977)', environmental purification was carried out to restore amusement facilities, install facilities for cherry blossom viewing, and develop the place into a national zoo. In the 'Reconstruction Period of Changgyeonggung(1983~1986)', restoring function as an urban park, reserving green areas, the outside space was recreated in the traditional feel, and the forest area was generally maintained. In the 'Supplementation Period of Traditional Landscape Architecture Space(1987~2009)', a uniform green landscape was created with pine trees and various vegetation landscapes centered on the flower beds. In the 'Improvement and Maintenance Period of Viewing Environment(2010~2022), a master plan was reestablished on the premise of utilization, but maintenance has been carried out in a small scale centering on unit space. Third, regarding the validity of the landscape restoration and maintenance, It was found in terms of 'originality' that the recovery of the palace system has not been expanded for over 40 years in existing areas. The 'characteristics of the times', which shows whether multi-layered history was taken into account, Changgyeongwon was excluded from the discussion in the process of setting the base year twice. In terms of 'integrity,' the area of the Grand Greenhouse where the historic states coexists needs a maintenance policy that binds the greenhouse, carpet flower bed, and Chundangji Pond. The 'utility' identified as the utilization of spaces suggests the establishment of a sense of place in the Grand Greenhouse area, which is concentrated with programs different from other areas.

The purpose of this study was to determine the preference and purchasing intention on necktie pattern designs according to male consumers' fashion lift style. Written questionnaires were handed out to 300 male consumers of the 20-40 years old in Seoul and surroundings, who were accessed by a convenience sampling method. The questionnaires were to classify male consumer groups according to the fashion life style, to examine characteristics, needs and wants of each group. The stimuli of 8 kinds of necktie patterns in black & white, and the semantic differential scale were applied to evaluate the preference and purchasing intention on necktie pattern design. A total of 265 samples were analyzed by factor analysis, cluster analysis, ANOVA, crosstabs and $X^2$-test through SPSS package program. Six factors in their fashion life style were extracted as follows: those were 'fashion-oriented', 'traditional conservative', 'brand-flaunting', 'personality-oriented', 'practicality-oriented' and 'unconcerned' life style. With these life style sub-dimensions, male consumers were segmented into five groups: these groups were 'strong personal seekers', 'practical brand seekers', 'traditional personal seekers', 'active fashion seekers', 'unconcerned group'. Each of these groups of male consumers showed significant differences in the preference and purchasing Intension of necktie pattern designs according to their fashion life style.
