The objective of this study was to contribute to the enhancement of food labeling and the development of food labels which are more informative to consumers. The questionnaires had been collected from adult female consumers living in Seoul, Kyonggi, Choongnam and Chungbuk province. Out of 950 answers collected 792 were analyzed. Ninety two percent of respondents were aware of food labels, however only 67.6% of them knew about the fact that food labeling was regulated by the law. Respondents recognized the major purpose of food labeling as informing and protecting the consumer. Most of the respondents answered that they confirmed the contents of food labels at the time of purchase especially with regard to safety aspects, such as expiration on data and manufacture date. Eighty four percent of the respon dents showed confidence in the contents of food labels.The rests answered they were hot confident because they experienced directly, or indirectly discord of food contents in fact and in label.

This research aimed to determine the quality characteristics of kochujang made of sword bean chunggukjang. The effects of chunggukjang addition were compared in products fermented for 90 days. During the fermentation period of kochujang, sword bean chunggukjang was added at 0, 2, 5, 8, and 10%. The moisture content ranged from 40.24 to 42.83% (w/w). After 90 days of fermentation, sodium chloride was at around 10.2 to 10.3%, which was not much different from that of control kochujang (SBC 0) before and after fermentation. The color values were not significantly different between SBC kochujang and traditional kochujang. The microbial counts in 0, 2, 5, 8, and 10% SBC kochujang fermented for 90 days were around $5.42{\times}10^7$ to $9.59{\times}10^7$ CFU/g for aerobic viable cells, $1.14{\times}10^2$ to $9.73{\times}10^2$ CFU/g for yeast, and $8.49{\times}10^2$ to $1.25{\times}10^3$ CFU/g for Bacillus cereus. Sensory evaluation of kochujang showed that the comprehensive preference was 5.40, 5.15, 6.30, 6.10, and 6.95, respectively, for SBC 0, 2, 5, 8, and 10%. In conclusion, the quality difference between SBC and traditional kochujang was not significant, and sensory evaluation of kochujang showed that SBC 10% received the highest score.

This study was carried out to investigate the proximate composition, mineral content, pH, acidity, color, ASTA value, free sugar content, and capsaicinoid level of Cheongyang pepper (Capscium annuum L.) cultivated in 13 different regions. For proximate composition of Cheongyang pepper, protein, lipid, and ash contents showed wide ranges of 12.74~19.98%, 4.54~7.17%, and 6.07~9.81%, respectively. Calcium, magnesium, iron, sodium, and potassium are major minerals found in Cheongyang pepper. Further, pH, total acidity, a value, and ASTA value showed wide ranges of 4.86~5.26, 2.10~4.25%, 28.89~37.12, and 76.54~139.57, respectively. Free sugars were fructose (8.55~17.06%) and glucose (3.25~10.47%), but sucrose and maltose were not detected. Capsaicin and dihydrocapsaicin contents were in the range of 100.27 to 261.54 mg% and 51.01 to 84.58 mg%, respectively. Capsaicinoid contents were above 200 mg% for the 11 cultivation regions. According to our results, Cheongyang pepper may be affected by environmental conditions such as different cultivation region more than genotype.

This study estimated the fiberboard demand using VAR and econometric model, and compared the prediction accuracy of the two models. And the variance decomposition and impulse response were analyzed using VAR model, and predicted the fiberboard demand. The VAR model was specified with lagged dependent variable, lagged own price, lagged construction product, dummy. The econometric model was specified with own price, substitute price, construction product, dummy. The dummy variable reflected the abrupt decrease in fiberboard demand in the late 1990's. The results showed that the fiberboard demand prediction can be performed more accurately by VAR model than by econometric model. In the VAR model of fiberboard demand, after twelve months, the construction product change accounts for about fifty percent of variation in the demand, and the own price change accounts for about thirty percent of variation in the demand. On the other hand, the impact of a shock to the construction product is significant for about twelve months on the demand of fiberboard, and the impact of a shock to the own price is significant for about six months on the demand of fiberboard.

To investigate the mating system of clones in the seed orchard of Japanese red pine, parameters of mating system, such as outcrossing rates, number of potential pollen contributors, and degree of pollen contamination, were estimated in the seed orchard of Japanese red pines on the basis of DNA data including 4 nSSR and 6 cpSSR markers. Estimates of outcrossing rates were ranged from 94.9 to 100% with an average of 98.9% on the basis of the analysis of cpSSR haplotypes. They were ranged from 90.3% to 100% with an average of 95.9% on the basis of the analysis of nSSR genotypes. However, cross checking of both DNA markers revealed that the seeds presumed to be products of self pollination were turned out to be generated by pollination between mother tree and other tree (i.e., 100% of cumulative outcrossing rate). Estimates of pollen contamination ranged from 43.6% (Gangwon-10) to 56.4% (Gangwon-12) with the average of 48.9%. On the basis of pooled cpSSR haplotype of each seed, maximum number of 21 pollen contributors were verified from the seeds reproduced by Kyungbuk-38. Minimum number of 13 pollen contributors were verified in Gangwon-10. Mean of 16.2 pollen contributors were verified from a total of 5 mother trees. In conclusion, considering pretty high outcrossing rates between clones within a seed orchard, it may be expected that a fairly good genetic potential of the seeds, produced in '77 plot of the seed orchard of Japanese red pines at Anmyeon island, may be guaranteed. Observed results from the analysis of mating system of Japanese red pines in a '77 plot of the seed orchard may also provide useful information for the establishment and management of the seed orchard of the progressive generation.

The Echinacea, which has been commonly known as a species of composite herb of dicotyledonous plant, has been used in native American traditional medicine for the treatment of diseases like colds or other infections in North America. We artificially cultured the adventitious roots of Echinacea angustifolia using the bioreactor culture system from Echinacea angustifolia and evaluated the efficacy as a cosmetic ingredient for skin care. Several studies previously have reported neogenesis, wound healing and inflammatory inhibition effect of Echinacea angustifolia but other efficacies were not well known. In the present study, we investigated the cosmetic efficacy to know applicable value of adventitious roots cultured from Echinacea angustifolia as a cosmetic ingredient. The adventitious roots extract of Echinacea angustifolia has superior anti-oxidant effect and matrix metalloproteinase-2 inhibitory effect, compared to natural Echinacea angustifolia. These results indicate that the adventitious roots extract cultured from Echinacea angustifolia presents a new possibility of being applicable to skin care and anti-wrinkle products as a cosmetic ingredient.

A standard for national seismological observatory was proposed on 1999. Since then, Quanterra digitizer has been installed and is operating on almost all of seismic stations which belong to major seismic monitoring organizations. Quanterra digitizer produce and transmit real-time event packet and data packet. Characteristics of event packet and arrival time of each channel's data packet on data center were investigated. Packet selection criteria using signal to noise ratio (hereafter SNR) and signal period from real-time event packet based on 100 samples per second (hereafter sps) velocity data were developed. Estimation of epicenter using time information of the selected event packet were performed and tested. A series of experiment show that event packets were received approximately 3~4 second earlier than data packets and the number of event packet was only 0.3% compare to data packets. Just about 5% against all of event packets were selected as event packet were related P wave of real earthquake. Using the selected event packets we can estimate an epicenter with misfit less than 10 km within 20 sec for local earthquake over magnitude 2.5.

The red ginseng marc was roasted at various conditions and its organo-leptic properties and flavor components were investigated. Scorched-rice odor and roasted odor and the roasted red ginseng marc powder were much stronger than those from the unroasted red ginseng marc powder while earth odor, old-rice odor, metalic off-odor and woody odor were much weaker than those from the unroasted red ginseng marc. Savory odor and scorched-rice odor as well as savory taste and astringent taste from the water-extract of red ginseng marc roasted at $200^{\circ}C$ were stronger, but smoky odor, woody odor, biner taste and rough taste were weaker than those roasted at $230^{\circ}C$. Seven kinds of pyrazines, two kinds of carbonyl compounds, seven kinds of acids, two kinds of esters, five kinds of phenolic compowlds, maltol and six other compounds were identified as flavor components in distillate from red ginseng marc roasted at $200^{\circ}C$ for twenty minuties. Of them pyrazines and maltol are thought to be compounds which have characteristic odor such as roasted odor and/or scorchedrice odor in the roasted red ginseng marc.

Recently, service-related products have gained more attention than general products on the existing social commerce sites. Based on the situation, the effect that the service quality of social commerce has on customer satisfaction was analyzed in this study. It is a study that analyzes how much the service quality affects the customer satisfaction after the purchase, targeting consumers who have made purchases of social commerce products. In the case of social commerce, it is well-known that the diversity and convenience of products have a significant effect on customer satisfaction. Social commerce is currently being dumped beyond the 900 sites and dozens of cases of news, real-time searches of popular portal sites appeared not to be bored enough to related sites to drive the popularity coming quickly dug into our everyday lives of human beings. Yet the perception of social commerce seems not properly established because of the new concept was suddenly going to go through penetration without a collective interpretation and acceptance process. Most of the companies that often mimic the syoseol commerce is large, the blame did not depart from the forms of social shopping. We believe that personal and exhibit their skills and talents, and to wonder to see the social rather than the individuals who make unilateral companies.

For 20 taxa of Korean Allium, including 16 species and 5 varieties, examined were morphological characters (i.e. sexuality, structure and shape of underground part, types and growing patterns of leaf and scape, and shapes of perianth, filament and pistil). The specialization and the evolutionary trends of taxonomic characters were inferred from morphological examination. Taxonomic relationships and system of Korean Allium were also studied. The characters showing evolutionary trends were the structure and shape of underground part including rhizome and bulb, leaf, scape, inflorescens, filament and ovary. It seemed that thin and short rhizome developed from thick and long one, and the membranous simple bulb tunic evolved into fibrous reticulate one. The presence of hyaline sheath in A. monanthum of sect. Microscordum was apomorphic. Both angular leaf blade with 2-rowed vascular bundle and flat blade with 1-rowed vascular bundle were developed from terete one with 2-rowed vascular bundle. The base of filament have differentiated from entire to toothed, and 2-ovuled ovary as well as erect scape before flowering was plesiomorphic type. In addition, sexuality, structure of underground part, the presence of hyaline sheath and cross-section structure of leaf were taxonomic characters with the level of the subgenus in this genus. Shape of rhizome, bulb, leaf, scape and pedicel discriminated each section from other ones in the subgenera easily. The shape and arrangement of perianth and filaments were the diagnostic characters for species level along with shape of ovary and stigma.
