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.

Conditions of fermentation for the production of demethyltetracycline were examined using the mutant, which was obtained through the cell fusion of demeclocycline producing strains, The optimum temperature and the initial pH of broth for demethyltetracycline fermentation were $25^{\circ}C$ and 6.7, respectively. Unlike any other cases, the control of pH with alkali solution during the fermentation process affected the productivity. As a general rule, the larger the inoculum size the higher the early consumption of sugar and the viscosity of broth, which means that fermentation proceeds more rapidly as the inoculum size is increased. The highest productivity was shown when the inoculum size was 5% (v/v), and the phase of seed also influenced the fermentation. Among the parameters of pre-culture thus examined, pH was the most important factor.

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%.

With a rapid development of smart devices, the consumption of digital media contents has become much faster. As a result, there has been a rising demand for diverse stories, and cultural archetypes have been reproduced to crate these stories. An archetype is an act inherent in collective unconsciousness. Since it is a prototype stemming from imagination and experiences, the distortion or deterioration of the archetype could even threaten the identity of national tradition. This study analyzed western contents which have been successful and domestic ones that have failed in the reproduction of their archetype, investigated aspects in the reproduction of cultural archetypes and reviewed future storytelling methodology.

Purpose: The purpose was to develop a preliminary scale to measure Korean adolescents' health behaviors through a qualitative approach, to evaluate the scale psychometrically, and to develop a final scale. Methods: Participants were 61 adolescents for qualitative interviews and 1,687 adolescents for the psychometric evaluation. Procedure included content analysis of interviews to identify health behavior categories for Korean adolescents, pre-test to confirm that preliminary scale items were understandable, content validity by an expert panel, development of the web-based computer-assisted survey (CAS), and psychometric analysis to determine reliability and validity of the final scale. Results: A final scale was developed for both paper-and-pencil and CAS. It consisted of 14 health behaviors (72 items), including stress and mental health (10), sleep habits (5), dietary habits (12), weight control (4), physical activity (4), hygiene habits (5), tobacco use (5), substance use (2), alcohol consumption (4), safety (4), sexual behavior (9), computer use (3), health screening (4), and posture (1). Conclusion: The scale's strong points are: 1) Two thirds of the final scale items are Likert scale items, enabling calculation of a health behavior score. 2) The scale is appropriate to Korean culture. 3) The scale focuses on concrete health behaviors, not abstract concepts.
