BACKGROUND/OBJECTIVES: The increased consumers' interests in health and food safety have increased the demand for organic foods. Many studies have been performed on consumers' purchase intentions for organic foods and their influencing factors, and various studies have shown that the prices of organic foods and the consumers' willingness to pay are important influencing factors. This study examined the payment value of organic foods and agrifood consumer competency index according to the food-related lifestyles in South Korean consumers. SUBJECTS/METHODS: A cross-sectional analysis was performed using the 2019 Consumer Behavior Survey for Food. A total of 6,176 participants aged 19 to 74 years (male: 2,783, female: 3,393) were included in the analysis. RESULTS: Three factors were extracted by factor analysis (rational consumption-seeking type, convenience-seeking type, and health, and safety-seeking type) to explain the consumers' food-related lifestyles. The results of cluster analysis suggested that consumers were classified into 3 food-related lifestyles as the 'exploratory consumers' (n = 2,485), 'safety-seeking consumers' (n = 1,544), and 'passive consumers' (n = 2,147). Exploratory consumers showed a significantly higher willingness to pay for imported organic foods (P < 0.05). Safety-seeking consumers had a significantly higher willingness to pay for domestic organic foods (P < 0.05). For the agrifood consumer competency index, exploratory consumers had the highest score, followed in order by safety-seeking consumers and passive consumers. CONCLUSIONS: These results provide basic data in understanding consumption tendency for organic foods and agrifoods based on food-related lifestyles of South Korean consumers.

`Bio morphism` are constituted in paintings where the artists try to embody the elementary properties of living creature as of growth and durability. They are the most appropriate concept of painting to harmonize human being with nature closely. The formative ways of them attach great importance to both unconsciousness and desire , as well as variations or dynamics, by noticing a flow of natural senses and feelings of human being. In other words, the formative ways are based on a recognition of nature as the intrinsic force of life, with the result that aesthetics of incompleteness is embodied in images. Therefore they are clearly distinguished from that of functional, geometric images. A tendency of painting at that time, in a word, 'return to figure and expression', means a conversion into organic images like the incomplete, atypical, and biomorphic forms, while denying the mechanical or geometric. Elizabeth Murray are analyzed, for these works are remarkable in the characteristics of 'Bio morphism'. Consequently the features of organic images, that is, 'the formative acceptance of natural figures, or an informality' and 'the force of free will, or an incompleteness', could obviously be revealed. It is a type that obtains a motif out of natural figures like an animal, a plant, or the concrete figures of human being. In conclusion, this thesis is focused on not only emphasizing that 'Bio morphism' were a major tendency among the various trends of postmodern painting in the 20th century, but also analysing both the painterly formation of organic images and the structure of them. In addition to these points, it is a central aim to evoke that Bio morphism should accurately be evaluated and positioned in postmodern painting. A new recognition of 'Bio morphism' is a peculiarity of the times that reflects a cultural aspect of the present, hence it should be recognized as another way to approach the postmodern painting.

In this study, 30 kinds of long-term and mature Korean soy sauce were collected and classified by the fermentation period, and the components related to taste and sensory characteristics were analyzed. A total of 4 kinds of organic acids were detected. The total organic acid content was in the range of 97.2~341.6 mg%, but did not show the tendency to increase or decrease in proportion to the aging period. The total free amino acid content was within the range of 3,001.0~3,834.7 mg% and showed a tendency to increase in proportion to the ripening period of the soy sauce. The contents of aspartic acid and glutamic acid subsequently increased in the long-term matured soy sauce. The ratio of essential amino acid to total amino acid was 31.6~35.7%, and the ratio of glutamic acid to total amino acid was 19.6~23.9%, respectively. The panel of 20~29-year-old indicated that the longer the aging period of soy sauce, the lower the preference while the panel of 30 or more years indicated that the longer the aging period of soy sauce, the higher the preference. This study was the first to investigate the quality of long-term matured soy sauce in more than one year.

Due to an overall increase of income, the general standard of living has improved and people have begun to be interested in being more healthy in their lives. This tendency has affected the food market, especially in relation to organic and eco-friendly food. Thus, the overall market size for those products has grown to give more choices to consumers. To examine the effect of the motive for choosing certain food products on the actual attitude and intent to purchase the products, a survey was given to 330 people living in Seoul, which resulted in 235 usable responses. The content of the questionnaire consisted of 18 questions on food choice motives, 3 questions on the attitude toward organic foods and 3 questions on the intention of purchasing for organic foods. The SPSS 12.0 statistics program was used to analyze of following: frequency analysis, factor analysis, reliability analysis, t-test, one way ANOVA and regression analysis. Five factors of food choice motives were obtained from the analysis: health, convenience, price, familiarity and environmental protection. The regression analysis showed that food choice motive, health and environmental protection factors have a positive relationship with organic food attitudes and organic food attitudes have a positive relationship with the intent to purchase organic food.

Objectives : This study was designed to evaluate the correlation between patterns of dyspepsia(acute dyspepsia, functional dyspepsia, dyspepsia with the organic disease) and autonomic nerve system dysfunction using HRV analysis. Methods : The patient group consisted of 88 patients diagnosed as a dyspepsia (Acute dyspepsia group-35 patients, Functional dyspepsia group-28 patients, Dyspepsia with the organic disease group-28 patients) who visited in the Oriental Medical Hospital of Dong-eui University from 2005.3.OO to 2008.8.OO. And the control group consisted of 33 patients diagnosed as a normal state of stomach during the same period. We checked HRV of the 4 groups over 5 minutes and compared the HRV index between groups. Results : 1. HF, LF, VLF and TP were significantly lower in the acute dyspepsia, functional dyspepsia and organic dyspepsia patient group than in the control group. 2. HF, LF, VLF and TP were higher in the acute dyspepsia patient group than in the organic dyspepsia patient group, but the differences were not statistically significant. 3. HF, LF, VLF and TP were higher in the acute dyspepsia patient group than in the functional dyspepsia patient group, but the differences were not statistically significant. 4. HF, LF, VLF and TP were lower in the functional dyspepsia patient group than in the organic dyspepsia patient group, but the differences were not statistically significant. Conclusions : Compared to the control group, all of the dyspepsia patient groups showed the tendency that the overall activity of the autonomic nervous system and the activity of sympathetic nerves decreased. Although there was no significant difference in the suppression of the autonomic nervous system, chronic dyspepsia patient group was lower than acute dyspepsia patient group, functional dyspepsia patient group was lower than the organic dyspepsia patient group in HRV.

The study examined fire resistance of concrete followed by change of mixed rate in PP and NY composite fiber and the results were as follows. In the event of fluidity in concrete not set, plane satisfied 600±100, its target slump flow, and fluidity was reduced as organic fiber's mixed rate was increased. Air amount satisfied 3.0±1.0, its target air amount, and didn't have distinct differences in reduction and increase according to organic fiber's kind and change of its mixed rate. However, it had a tendency that fluidity was reduced as the mixed rate was increased. In characteristics of hardening concrete, the 28th day compressive strength followed by organic fiber's kind and change of its mixed rate didn't have a lot of differences and satisfied high strength scope as about 70MPa. In spalling characteristics after fire resistance test, spalling was happened in non-mixture, plane combination, and P1N0. In other combinations, spalling resistance was happened. The relic compressive strength rate was 56%, the best condition, in P3N1(PP0.03%, NY0.01% compositeness) mixing PP fiber with NY fiber at once.

In this study, we used the Flux Balance Analysis (FBA) program to examine the behavior of hydrogen and organic acids according to seasonal changes in food wastewater collected from D city. The results showed that average hydrogen conversion rates in spring, summer, autumn, and winter were 1.06, 0.71, 1.21, and 1.13 mol H₂/mol of hexose_added, respectively, indicating a significantly lower hydrogen conversion rate in summer than in other seasons. This phenomenon is believed to occur because the carbohydrate concentration of the incoming food wastewater is low. In addition, Lactobacillus, the lactic acid-producing bacterium, was 21.3% in spring, 27.2% in summer, 17.5% in autumn, and 22.6% in winter. The most distinctive feature of the microbial community in summer was that 15.3% of the Ilyobacter was analyzed. It was confirmed that Ilyobacter, which is involved in the production of acetic acid and propionic acid, is closely associated with the tendency of increasing acetic acid and propionic acid and thus contributes to organic acid change. Clostridium, a hydrogen-producing bacterium, was 76.2%, 50.8%, 78.3%, and 74%, in spring, summer, autumn, and winter, respectively. It was confirmed that Clostridium dominates the microbial community by approximately 70% or more in all seasons except summer.

A total of 120 finishing pigs ([Yorkshire${\times}$Landrace]${\times}$Duroc) with an average body weight (BW) of $49.72{\pm}1.72kg$ were used in 12-wk trial to evaluate the effects of protected organic acids on growth performance, nutrient digestibility, fecal micro flora, meat quality and fecal gas emission. Pigs were randomly allotted to one of three dietary treatments (10 replication pens with 4 pigs per pen) in a randomly complete block design based on their initial BW. Each dietary treatment consisted of: Control (CON/basal diet), OA1 (basal diet+0.1% organic acids) and OA2 (basal diet+0.2% organic acids). Dietary treatment with protected organic acid blends linearly improved (p<0.001) average daily gain during 0 to 6 week, 6 to 12 week as well as overall with the increase in their inclusion level in the diet. The dry matter, N, and energy digestibility was higher (linear effect, p<0.001) with the increase in the dose of protected organic acid blends during 12 week. During week 6, a decrease (linear effect, p = 0.01) in fecal ammonia contents was observed with the increase in the level of protected organic acid blends on d 3 and d 5 of fermentation. Moreover, acetic acid emission decreased linearly (p = 0.02) on d7 of fermentation with the increase in the level of protected organic acid blends. During 12 weeks, linear decrease (p<0.001) in fecal ammonia on d 3 and d 5 and acetic acid content on d 5 of fermentation was observed with the increase in the level of protected organic acid blends. Supplementation of protected organic acid blends linearly increased the longissimus muscle area with the increasing concentration of organic acids. Moreover, color of meat increased (linear effect, quadratic effect, p<0.001, p<0.002 respectively) and firmness of meat showed quadratic effect (p = 0.003) with the inclusion of increasing level of protected organic acid in the diet. During the 6 week, increment in the level of protected organic acid blends decreased (linear effect, p = 0.01) Escherichia coli (E. coli) counts and increased (linear effect, p = 0.004) Lactobacillus counts. During 12-wk of experimental trial, feces from pigs fed diet supplemented with organic acid blends showed linear reduction (p<0.001) of E. coli counts and the tendency of linear increase (p = 0.06) in Lactobacillus count with the increase in the level of organic acid blends. In conclusion, 0.2% protected organic acids blends positively affected growth performance, nutrient digestibility, fecal gas emission and meat quality in finishing pigs without any adverse effects on blood parameters.

The purpose of this study presents useful data on the choice or development of floor covering from slip viewpoint by examining closely the impact of the changes in sliding experiments due to the wear of floor covering by walk. The result of wear practical test per ten thousand walks enforces some kind of popular floor covering and measure of coefficient of slip resistance as follows: (1) When surface of floor covering is in the state of wet, the degree of wear doesn't affect greatly in slip. (2) When surface of floor covering is in dry and clean state, most floor coverings have the tendency to lower the coefficient of slip resistance with the amount of walk on it. (3) Change in the tendency of slip resistance by wear appeared mainly due to the differences in the state of floor covering and organic floor covering appeared to have great reduction of coefficient of slip resistance than the inorganic ones. (4) According to the result of investigation on changes in tendency of coefficient of slip resistance due to the increase in the number of walk and if two hundred thousand walks were done, regardless of surface shape or kind of site, etc, the safety of floor covering, in slip viewpoint, greatly reduces.
