The purpose of this study is exploring the expressional characteristics of organic fashion design different from the past by analyzing the expressional characteristics of organic fashion design dependent on the digital paradigm and simultaneously suggesting the theoretical data required to understand the changing trend of organic design in relation to the paradigm of the age. The results of the research is as follows; The expressional characteristics of organic fashion design according to the digital age appeared to have same aspects. Pluralism respecting multi-culture, hybrid of multi-meaning image, circulation that can consistently circulated, non-hierarchical post-structure, de-boundary through dissolution of genres, digital nomad considering mobility, human centered through significant sensitivity, de-materialization of assimilation between reality and non-reality, conceptualization given the concept of designer, technology combining with digital technology. This study found that organic fashion design in the digital age has the same conceptual context as periodical paradigm freely circulating consistently by organically combining each individual. This can be understood as the trend of design implied in conceptual context that organic fashion design requires periodical paradigm.

Current status on the occurrence and the management of the major disease, insect and mite pests were investigated in the organic or non-chemical pest control orchards from 2005 to 2009. Numbers of certified organic or non-chemical apple orchards were increased from 14 in 2005 to 78 in 2008. Severe damages on leaves and fruits occurred by the several diseases such as marssonina blotch, bitter rot, white rot, sooty blotch and flyspeck, and the several insect pests such as apple leaf-curling aphid, woolly apple aphid, oriental fruit moth and peach fruit moth on the almost certified organic or non-chemical pest control orchards. About 10 and 18 environmental-friendly materials were used to control diseases and insect or mite pests respectively. But, lime sulfur and bordeaux mixture to diseases and machine oil, plant oil mixed with egg yolk, and pheromone mating disruptions to insect pests were effective to control under the adequate conditions. At present, it is extremely difficult to produce organic apples in Korea. Growers must consider about and solve so many conditions on the cultivar, weather, local site, marketing and so on, before when they decide to change from conventional or IPM(Integrated Pest Management) to organic or non-chemical pest control orchards.

This study aimed to analyze the effect of demographic characteristics of consumers and quality recognition factors on purchase intention of organic wine, and to provide preliminary data necessary for the development of wine industry. By factor analysis of collected surveys, quality recognition factors of both the experienced and non-experienced group of organic wine environment/health, varieties of grapes, price, and four brand elements. First, among demographic characteristics, only income level hae a significant influence on the changes in quality recognition causes. Each of quality recognition causes of organic wine had a significant relation with purchase intent. The result of our analysis suggested that 'environment/health' was most influential for the experienced group, and 'health' was most influential for the non-experienced group. Therefore, this hypothesis is supported.

This study was performed to examine the effect of ${\gamma}$-irradiation on the volatile organic compounds of Cuscutae Semen (Cuscuta chinensis L.). The volatile organic compounds of non-irradiated and 10 kGy ${\gamma}$-irradiated Cuscutae Semen were isolated using SDE apparatus and analyzed by GC/MS. Limonene, ethanol, (E)-2-decenal, hexadecanol, nonanoic acid and nonanal were detected as dominant compounds. Before irradiation, the total concentration of volatile organic compounds of Cuscutae Semen was approximately 189.90 mg/kg. After irradiation at 10 kGy, total concentrations increased to 299.46 mg/kg, but, the profile of volatile compounds including the essential oils of Cuscutae Semen was not differ from non- and irradiated sample. Therefore it was improved the extraction yield of useful compounds such as limonene, menthol, piperitone and isomenthone by irradiation.

Quantitative data of 50 non-polar organic compounds constituting $PM_{2.5}$ were continuously collected and analyzed from June 2016 to October 2017 (approximately 17 months) at Ichihara, one of the largest industrial areas in Japan. Target non-polar organic compounds including 21 species of polycyclic aromatic hydrocarbons (PAHs), 24 species of n-alkanes and 5 species of phthalate esters(PAEs) were simultaneously measured by gas chromatography/mass spectrometry. Basically, the average concentrations of the total PAHs, n-alkanes and PAEs in each season remained nearly level, and seasonal variations were little throughout the study period. These results suggest that the emission sources, which are not influenced by the seasons, are the dominant inputs for the target organic compounds. Diagnostic ratios of PAHs, assessment of n-alkane homologue distributions, carbon preference index, and the contribution of wax n-alkanes from plants were used to estimate source apportionments. These results indicate that anthropogenic sources were the main contributor for most PAHs and n-alkanes throughout the study period. The concentrations of PAEs selected in this study were low because emission amounts of these chemicals were little within the source areas of the sampling site. To our knowledge, this study is the first attempt to simultaneously measure a high number of non-polar organic compounds in $PM_{2.5}$ collected from the ambient air of Japan, and the resultant data will provide valuable data and information for environmental researchers.

A nonthermally sterilized raw apple vinegar was manufactured using an ultra-fine filtration process (0.2 ㎛ membrane filter) and its quality was comparable to commercially available vinegar products. First, using apple concentrate as a raw material, it was possible to produce non-thermal sterilized Using a two-stage fermentation process of alcohol and acetic acid fermentations, a non-thermally sterilized raw apple vinegar with pH 2.94 and an acidity of 6.20% was produced from an apple concentrate. The fermentation process increased the browning index significantly. However, the fundamental quality parameters of the non-thermal sterilized raw apple vinegar (A) with sterilized apple vinegar (B) did not differ significantly. The pH (2.92-2.95) of apple vinegar (A and B) was higher than that (pH 2.65-2.70) of commercial vinegar (C and D), and the total acidity, which is in the range of 6.20-6.21% and 6.53-6.90%, respectively, was higher in samples C and D than in samples A and B. However, four kinds of organic acids were detected in non-thermal sterilized raw apple vinegar (A), and its total organic acid content (6,245.00 mg%) was significantly higher than that of other samples (B, C, D) (p<0.05). In particular, malic acid content, as a main organic acid in apples, was very high in sample (A) (244.83 mg%) and sample (B) (210.21 mg%), compared to commercial products C (125.78 mg%) and D (86.90 mg%). The total polyphenol content and antioxidant activity of fermented apple vinegar (A, B) were more than twice as high as those of commercial products (C, D). Vinegar A had higher total polyphenol content than vinegar B. The above results suggest it is possible to manufacture and commercialize non-thermal sterilized raw apple vinegar with higher organic acid content and antioxidant properties using ultra-fine filtration.

Changes in taste components of Backilju, an traditional alcoholic beverage of Korea, were investigated. Ethanol(17%) was the most abundant, and then isoamylalcohol(23mg%) and methanol(8mg%) were also detected in a small amount in Backilju. Major non-volatile organic acids were lactic and malic acid, followed by citric, fumaric and succinic acid. Arginine, phenylalanine and glutamic acid were major free amino acids and essential amino acid content was 230∼560 mg%, which was 45∼48% of total free amino acids. The major fatty acid of total lipid was palmitic acid(37∼43%). It has been found that the Backilju contained more free amino acids and alcohols than other Korean Yokjus.

Eviction characteristics of two typical friction materials (non-asbestos organic and low-steel friction materials) for an automotive brake system were investigated using an inertial brake dynamometer. In particular, the effect of sliding speed on friction coefficient was carefully investigated employing various test modes. The two friction materials were developed for commercial applications and were different mainly in the type and the amount of metallic ingredients in the friction material. The dynamometer test showed that the low-steel friction material was sensitive to the sliding speed exhibiting a negative $\mu$-v relation. On the other hand, the non-asbestos organic friction material was less sensitive to the sliding speed. The low steel friction materials with a negative $\mu$-v relation also induced larger vibration amplitude during brake applications.

Volatile aroma components, non-volatile organic acids in lamina and stems of flue-cured(NC 2326) and burley ( Burley 21) were analyzed by gas chromatography and mass spectrometry, respectively. Then compositional differences of these components between lamina and stems were discussed. The contents of volatile components were higher in flue-cured than in burley tobacco, and it was also higher in lamina then in stem. The major aroma components in lamina were neophytadiene , nicotine, solanone and benzyl alcohol but those in stems were palmitic acid, neophytadiene, nicotine, solanone and phenyl ethyl acetate. On the other hand, the contents of non-volatile organic acids were higher in burley than in flue-cured tobacco, and these values of burley tobacco were higher in lamina than in stem but flue-cured tobacco were higher in stem than in lamina. The major acids in all the above four tabacco samples were malic, citric, oxalic and linolenic acid.
