  • The production of Korean ginseng, one of the most important medicinal root crops, is limited by many factors including soil sickness, root rots in fields as well as during storage prior to consumption. Although much research has been conducted on the diseases in field condition, little information is available on the control of postharvest roots rots. To obtain better management strategy of postharvest root rots in ginseng, biological control using antagonistic bacteria was attempted. Of 208 bacteria obtained form suppressive soil samples, 4 were selected based on the inhibitory effect on mycelial growth of two major causal fungi for postharvest root rots in ginseng, Botrytis cinerea and Fusarium solani. The culture filtrates of these bacterial antagonists greatly inhibited the conidial germination of both pathogenic fungi and produced abnormal morphology such as swollen germ tubes in F. solani and vacuolation of nongerminated conidia in B. cinerea. The population levels of bacterial antagonists on the ginseng roots were gradually increased up to 8 days of incubation. Postharvest root rots of ginseng caused by f. solani and B. cinerea were controlled in dipping tests in the ranges of 60∼80% by antagonistic Bacillus spp. obtained from suppressive soil. These results suggest that biological control using these antagonistic bacteria would be an alternative strategy to control postharvest root rots in ginseng.

  • Sports drinks help optimize and improve performance by delaying and eliminating the buildup of fatigue-causing substances in the body during exercise. Saengmaeg-san is a nature-friendly traditional beverage that has no side effects on the human body and can quench thirst. However, studies on the relationship between exercise ability and Saengmaeg-san are insufficient. The purpose of this study was to prescribe Saengmaeg-san during the summer training period of 4 weeks and to analyze the effect on body composition and exercise performance. Seventeen male participants were divided into 3 groups (Saengmaeg-san acid intake group [n=9], placebo group [n=8]), and body composition (height, weight, muscle mass, fat mass, BMI) and conducted exercise performance (total exercise time and HRmax). In our study, Saengmaeg-san intake had a positive effect on exercise performance, such as decreased body fat percentage, increased exercise time, and decreased HRmax. Therefore, Saengmaeg-san showed the potential as a sports drink. In the future, additional studies on fatigue-related substances, immune function-markers, and blood lipids are needed in order to clearly explain the change in exercise performance due to consumption of Saengmaeg-san.

  • This research developed satellite account for household production to measure the whole size of production in Korea. The standardized satellite account was designed on the basis of Ironmonger's IO table. Results of this research were summarized as follows. First, the economic values of male and female labor invested for household production was 1,560,000 and 5,380,000 Won, respectively. Female input was greater than male by 3.5 times. Second, the expenditure for durable goods for household production was on average 470,000 Won per year. Among the total expenditure, 36% was spent for household management activities, 25% for food preparation and 25% for cleaning and laundry. Results of examining the expenditure for durable goods in total production activities showed that more than half was spent for household production; 54% for household production, 39% for leisure, 4% for sleeping, and 3% for individual use. Third, among expenditure of consumption for intermediate foods for household production, expenditure for food was the greatest to be followed by expenditures for child care, other houseworks, and cleaning and laundry. Finally, the total value of household production in Korea turned out to reach 171 trillion won which was value of 36% of GDP(482 trillion Won) in 1999.

  • The developments of consumption culture and mass media have caused consumers to take a greater interest in appearance, and as a result, the appearance related industry has been rapidly developed. Since appearance serves as a means to attain a smooth and successful social life, women invest a lot of time in cultivating their appearance more prominently than others and are more agreeable to the criteria of beauty in society. This study is to analyze the degree of satisfaction of appearance in teens to women in their 50s as classified by their lifestyle. For the data analysis, the statistical program, SPSS WIN 14.0 was used. First, the results of examining the degree of interest in appearance, the degree of bodily satisfaction, and the degree of bodily importance showed that the interest in appearance was highest in the fashion pursuing group. The degree of bodily importance was highest in the economy-oriented group. Second, appearance management attitudes showed significant differences m hair attitudes, makeup attitudes, skin attitudes, face-lifting attitudes, and clothing attitudes, depending on the types of lifestyle. Third, it could be seen that the conservative-oriented groups were doing more skin care management than the other groups.

  • This study explores whether consumers' sustainable luxury purchase (SLP), which refers to luxury consumers' conscientious purchase behavior of "buying luxury for its timeless style and durable quality that leads to extended product usage and less waste," leads to luxury consumer pleasure (LCP). Furthermore, the current study examines whether LCP leads to positive post-purchase behavior reflected by sustainable divestment intention (SDI) and repurchase intention (RI). In addition, by building on Coping Theory, we explore whether luxury consumer guilt (LCG) positively moderates the relationship between LCP and SDI. Our empirical findings of the SEM analysis based on 452 valid responses demonstrate the significant relationships between SLP and LCP, between LCP and SDI, and between LCP and RI. This implies the importance of SLP in creating a favorable consumer response, which further leads to consumers' intentions to make a sustainable divestment and to repurchase luxury. Furthermore, the critical moderating role LCG plays in the relationship between LCP and SDI was supported, stressing the importance of guilt as a trigger of consumers' sustainable divestment behavior.

  • The aim of this study was to evaluate effects of modified glucomannan ($Mycosorb^{TM}$) on the antioxidant profile of egg yolk and tissues of newly hatched quail after aurofusarin inclusion in the maternal diet. Fifty-four 45 day-old Japanese quail were divided into three groups and were fed a corn-soya diet balanced in all nutrients ad libitum. The diet of the experimental quail was supplemented with aurofusarin at the level of 26.4 mg/kg feed in the form of Fusarium graminearum culture enriched with aurofusarin or with aurofusarin plus $Mycosorb^{TM}$ at 1 g/kg feed. Eggs obtained after 8 weeks of feeding were analysed and incubated in standard conditions of $37.5^{\circ}C$/55% RH. Samples of quail tissues were collected from newly hatched quail. The main carotenoids, retinol, retinyl esters and malondialdehyde were analysed by HPLC-based methods. Inclusion of aurofusarin in the maternal diet was associated with decreased carotenoid and vitamin A concentrations in egg yolk and liver of newly-hatched quail. Furthermore, lipid peroxidation in quail tissues was enhanced. Inclusion of modified glucomannan ($Mycosorb^{TM}$) in the toxin-contaminated diet provided a significant protective effect against changes in antioxidant composition in the egg yolk and liver. It is suggested that a combination of mycotoxin adsorbents and natural antioxidants could be the next step in counteracting mycotoxins in animal feed.

  • This study aims at reviewing the Kitsch aesthetics, grasping the relation between the Kitsch and consumption culture, and pursuing the intrincis meanings and expressive characteristics of Kitsch in the hair style and head dress in the 1990s. Kitsch generally implies a vulgarity, and a bad taste, and can be considered to be a kind of vicarious experience, the aesthetic deception and self-deception. In spite of these negative inplications of Kitsch, the aesthetic categories of Kitsch have been spread to public and been accepted by the public, with the help of the powerful promotion of the modern day mass media. 1. The intrincis meanings of Kitsch convey 1) escapism, 2) conformity, 3) amusements, 4) identification. 2. The expressive characteristics of Kitsch represent 1) aesthetic inadequacy: hair style and head dress showing the imperpectness, accumulation(superfluous ornaments), vulgarity, untidines. 2) resistance: hair style and head dress featuring deconstructional and violent forms revealing the uneasiness, and unsatisfaction of the given regularity. 3) humor: hair style and head dress featuring the innocence, humor, and fun for a relaxation and diversion. 4) hedonism: hair style and head dress with the erotic and sexual feelings. 5) retro, romantism: hair style and head dress featuring the elegance, femininity, folklore, ethnic, and nostalgia.

  • The purpose of this study is to identify the best firing condition for Celadon, which is one of the famous traditional pottery to represent Korean culture, by minimizing energy consumption, cutting firing time, shortening the time of processing ceramic making, in order to, save energy as well as to protect the potters' health. Most Korean potter starts their reduction from $950^{\circ}C$ to change kiln atmosphere. However on this study, reduction have started from $950^{\circ}C\;to\;1200^{\circ}C$ by increasing $50^{\circ}C$ at a time. Then the results are analyzed to be compared to previous Celadon, in colors, chroma, and brightness. As a results, it is found, that the best temperature for starting reduction is $1100^{\circ}C$, when chroma and brightness values to meet same with previous celadon. Therefore the best condition could be made by starting the reduction on $1100^{\circ}C$ to fire celadon, which would have shorten 2 hours of firing process and, at the same time, it could have saved the energy by 12%.

  • 스마트디바이스의 급속한 발전과 함께 디지털미디어적인 콘텐츠 소비속도가 매우 빨라지고 있다. 그로 인하여 다양한 이야기가 필요하게 되었고, 이야기를 창작하기 위해 문화 원형들의 재현이 많아지고 있다. 원형은 집단적 무의식 안에 내재된 행동이며, 상상과 경험에서 오는 전형적인 본보기인 만큼, 콘텐츠에 재현되는 원형이 왜곡되거나 변질되는 현상들은 민족 전통의 정체성까지도 위협할 수 있다. 본 논문은 원형 재현에 성공한 서양 콘텐츠와 원형재현에 실패한 국내 콘텐츠를 분석하고, 문화원형 재현의 실패에 따른 양상들을 파악하여, 향후의 스토리텔링 방법론을 고찰해 보았다.
