The purpose of this study was to predict the future urban activities effectively and rationally. For the purpose, a simulation model, based on SD, was built by integrating economic activities, land use and traffic of a city and by dividing Daegu Metropolitan City into seven districts and one county. To identify the effect of the development of a new city in the Dalsung County area, the future population and traffic volume of the city were predicted, using the model. The results are summarized as follows. The future population according to the development of a new city in the Dalsung County area was predicted, and the effects before and after the development twenty years later were compared. The future population of the Dalsung County was found to have slightly increased, whereas that of the adjoining Dalsuh Metropolitan District was found to has slightly decreased. For the other districts, there were no changes of the future population. It was found, therefore, that the development of a new city would have no effect on other districts. Then, the traffic volume according to the development of a new city in the Dalsung County area was also predicted. It was found that in the initial stage the traffic volume would increase with the increase in population of Dalsung County. It was predicted that particularly,. the traffic volume for the purpose of business would greatly increase. The traffic volume of Dalsuh Metropolitan District showed a slight decrease, whereas for the other districts, there were no changes of the traffic volume.

In this paper, to analyze the meaning of middle-aged men's economic activities, TEXTOM was used to analyze them. The data collection period is set from 2017 to 2019. Among the collected data, 100 refined words were converted into a matrix in which the degree of social connection was calculated, and the keyword network analysis was performed again with the NetDraw program. According to the study, middle-aged men put more meaning on their current work and family than their future retirement. Also, the related word commonly included in the top five for all three years was 'work'. Related words commonly included in the top 10 were 'old age', 'family', and 'work', and in 2018 and 2019, 'health' was included in the top 10. As a result of this, the middle-aged men living in the modern age are the generation who keep their families through economic activities and are increasingly interested in health and prepare for retirement. Therefore, policy support for stable economic activities is needed to improve the quality of life for middle-aged men. It is necessary to extend the retirement age, expand jobs and provide effective vocational training so that it can handle its role as the head of a family. In addition, measures should be taken to reduce the wage gap between highly skilled and low-skilled workers.

This study was performed to investigate the antioxidant and antidiabetic activities of soybean fermented with Monascus. Also, the changes in the content of isoflavones and Monacolin K were analyzed. It was observed that the glycoside forms of daidzin and genistin were converted to aglycones of daidzein and genistein within 6 days of fermentation. The product can be used as a health functional material that can increase bioavailability. Monacolin K production was found to increase significantly with the progression of fermentation with an increase to 0.04 mg/g and 0.44 mg/g on 6 and 12 days of fermentation, respectively. The DPPH radical scavenging activity of soybean fermented with Monascus was significantly increased compared to that of soybean. The protein expression of inflammation-related genes (TNF-α, IL-6, and COX-2) in the MIN cell was significantly increased in the presence of alloxan compared to the normal group, but a decrease was observed in the presence of soybean fermented with Monascus. In conclusion, soybean fermented with Monascus showed the highest antidiabetic and antioxidant effects. These results suggest that soybean fermented with Monascus has the potential to be used as a beneficial ingredient with antidiabetic and antioxidant effects.

본 연구에서는 실시간 통신 기술을 적용한 온라인 수업 토론 활동의 중층적 구조와 역동적 전개 양상을 개념적 수준에서 분석하였다. 문화역사적 활동이론에 근거하여 온라인상에서의 개별 발화를 활동체제의 산물로 간주하였으며, Alderfer의 욕구 위계이론을 주체의 동기와 의도를 분석하는 틀로 활용하였다. 온라인 수업 토론은 전체로서 하나의 활동체제로 작동하며, 특별히 활동 주체들의 욕구에 따라 기본 방향과 성격이 규정된다. 주체의 존재, 관계, 성장의 욕구에 따라 이들의 수업 토론 활동은 물리/생물적 차원, 문화/제도적 차원, 사회/관계적 차원, 협력적 지식 구성의 차원으로 규정된다. 이는 개별 활동 체제 안에 중층적으로 존재하며, 각자의 관심과 처지에 따라 배열이 달라지고, 동시에 활동체제 간의 협력과 갈등의 요인으로 작용한다. 이를 통해 집단적 토론 활동은 복잡하고 역동적으로 발전한다.

Honey was diluted with different percentages of water and was analysed rheologically at room temperature of 27℃. The rheological profiles of pure and impure honey samples were measured at low shear rates (0.01-4.16s^-1). This work developed a structural kinetic model, which correlated well with the rheological data. The new model was used to categorise honey samples using their average molecular weights as one of the distinctive properties. Also, the kinetics order in the new model predicts the number of active components in the "honey" undergoing deformation. Honey produced third order kinetics to depict the monomers, oligomers and water content in honey. Pure honey exhibits peculiar non-Newtonian rheological behaviour. The behaviour of water is Newtonian. Dilution of honey with different percentages of water turns the resulting fluid Newtonian from 10% dilution with water. This study analysed the antibacterial activities of honey and serially adulterated samples against Staphylococcus aureus and Pseudomonas aeruginosa. The antibacterial analyses of honey were conducted using Kirby Bauer's well diffusion method. The results indicated that pure honey exhibited a zone of inhibition against both organisms. Also, the diameter of the zone of inhibition decreased with increasing dilution of honey, suggesting a correlation with the rheological method.

The purpose of this study was to investigate the factors that determine whether college graduates majoring in culinary arts are employed. To achieve this purpose, this study largely divided the factors affecting the status of employment into the personal background, college life, and employment preparation activities factors. And, the data of 164 graduates who graduated from culinary arts-related departments participating in the Graduate Occupational Mobility Survey (GOMS) were used. The analysis results are summarized as follows. First, it was found that the health status and experience of job-seeking activities of college graduates majoring in culinary arts decreased the employment probability. On the other hand, major satisfaction and certification acquisition were found to increase the employment probability. Second, the health status and experience of job-seeking activities of graduates who participated in 2018GOMS were found to decrease the employment probability, and major satisfaction and grade were found to increase the employment probability. Third, it was found that only the health status of graduates who participated in 2019GOMS affected the status of employment. Therefore, in order to increase the employment rate of culinary arts majors at the end of COVID 19, universities need to make efforts to increase their satisfaction with their majors and their grades while attending college.

Flavonoids including quercetin and rutin are a group of naturally occurring compounds widely distributed in plants, especially in buckwheat. Thus, cereal and the leaf of the plant have increasingly used as a source of nutritional and functional foods such as noodle, cake or soup in Korea, Japan and other countries. This study investigated comparative effects of dietary rutin rich in buckwheat and its aglycone, quercetin, on serum biomarkers and antioxidant parameters in rats treated with chronic ethanol. Rats were fed with the liquid diets prepared by the method of Lieber Decarli. Serum alanine transaminase (ALT) and aspartate transaminase (AST) activities increased significantly by alcohol feeding. Dietary flavonoids including rutin, quercetin and their mixtures (1/1, v/v) decreased significantly the activities of serum ALT whereas the feeding of quercetin decreased only the activity of serum AST. The concentration of serum malondialdehydes elevated by chronic alcohol feeding decreased markedly in all the experimental groups that were fed with the flavonoids; however, the combined administration of quercetin or rutin, but not that of rutin or quercetin alone decreased significantly the concentration of liver malondialdehydes to the normal range in rats fed without ethanol. Our results suggested that dietary combined mixture of rutin and quercetin might be effective in ameliorating adverse responses seen in rats exposed to ethanol chronically.

The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization's safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.
