S. cerevisiae ATCC 24858을 이용한 ethanol 생산에서, aeration 효과를 ethanol 수율, specific ethanol production rate, ethanol 생산성 측면에서 분석하여, 반복 유가식 공정전략을 설계하였다. Ethanol 수율과 ethanol 생산성은 공기를 0.33 vvm 넣었을 때, 공기를 넣지 않고 배양한 것에 비하여 더 큰 값을 보였고, 24시간 마다 배지를 교체한 배양이 36시간 마다 배지를 교체한 배양 보다 더 큰 값을 보였다. 총 ethanol 생산량 값이 가장 큰 경우는 0.33 vvm의 공기를 넣고, 배지를 24시간마다 완전히 갈아주었을 때이고, 이때 가장 많은 703.8 g의 ethanol이 생산되었다.

Methods of lichen-derived culture were spore- and thallus-derived cultures. Spore-derived culture was modified and thallus-derived culture was established for our two decades. We maintained about 500 lichen-derived cultures by using both methods. In recent several years, we have investigated to screen various pharmacological activities in lichen-derived cultures for the first time and found some activities in our cultures.

Aspergillus을 이용하요 생리적 제성질을 조사하였던 바 다음과 같은 결론을 얻었다. 1) 각 균주들은 각각 그들의 특성을 가지고 있었으며 이로서 균동정의 가능성을 나타내었다. 2)Amilase측정결과에서 보면 비교적 역가가 높은 균주들이 관찰되었으며, 이는 일주문의 경과에 따라 역가가 증가하였으나 protease의 역가는 우수한 균주를 발견키가 어려웠다. 3)Iodine의 착색대와 비착색대의 비율에 의한 역가의 정성적인 측정이 가능하였다.

Consumer behavior is driven by culture; and culture is contextual. Therefore, human behaviors such as those exhibited in consumption behavior should not be measured and compared cross-culturally by using cultural specific mea-sures or paradigms which assume a universal reality, time and context free. Since it is known that consumption behavior is influenced by culture, and cultures in the United States differ from those in Korea, the assumption of universal ‘truths’ which can be known is inappropriate. To employ a paradigm with invalid assumptions automatically leads to the lack of validity, a must for truth claims in the positivist paradigm. Thus, 'truths' in the research reported must be suspect.

Information culture is a concept with multiple and sometimes conflicting definitions. Nevertheless at a time when social and cognitive aspects of information and communication systems are recognized as being of similar significance as the technological functionality, the concept of information culture is demonstrating considerable value. This paper explains the concept of information culture and considers its value from two main perspectives: firstly as providing an analytical tool, and secondly as a means of providing practitioners with insight and sensitivity to the organisational contexts of their workplaces.

Optimum conditions for vacuum-drying ad cultivation of yeast cells for the production of active dry yeast were examined. At lower temperature, more drying time was required to dry the yeast pellet to reach the desirable water content(8%). Optimum temperature of vaccum oven and time for drying was 63$^{\circ}C$ and 90 min, respectively. Optimum medium composition for flask culture using cane molasses as the substrate were 0.25% sugar, 0.013% $K_2$HPO$_4$, 0.1% $K_2$HPO$_4$. and 0.125% (NH$_4$)$_2$SO$_4$. Culture temperature $25^{\circ}C$ gave the highest survival rate of dired yeast. After finishing fed-batch culture and the culture was left in the fermentor without adding any sugar or nutrient, survival of the dried yeast harvested from the fermentor increased to 86.0% after 36 hr. It was also observed that the yeast cells with higher budding rates showed lower survival rate.

Reflecting a particular place and time, from the agrarian society, through the Industrial Age, furniture has been one of the closest factors to our housing life and developed continuously. The information age representing digital, information and telecommunication generally gave a wide range of individuals and societies various phases of culture shock that had never been experienced so far, among which the change of the attitude toward work and marriage influenced on housing life style, they have required unexplored style and function of furniture additionally. People so called the singles has recently become a culture code reflecting the present time, they already have built their own territories in society, economy and culture. The ideas about a variety of furniture for the singles, which consider the housing culture of the singles, has been floated, therefore furniture for the singles are main streamed into home furniture category, required characteristics of furniture for the singles are drawn, furthermore some design examples are suggested on the basis of those characteristics in this study.

Roridin E, produced by Podostroma cornu-damae, is a mycotoxin with anticancer activity. To increase the content of roridin E, submerged culture conditions were optimized using response surface methodology. Three factors, namely, medium initial pH, incubation time and agitation speed were optimized using a Box-Behnken design. The optimum submerged culture conditions to increase the content of roridin E included a medium with an initial pH of 4.0, an incubation time of 12.90 days, and an agitation speed of 63.03 rpm. The roridin E content in the submerged culture, under the aforementioned conditions, was 40.26 mg/L. The findings of this study can help lower the current price of roridin E and promote its related research.

Modernization drastically changed the cosmetic culture of Korea and Japan. A classic case that shows this is the appearance of the term 'Hyangjang (香粧)'. This paper investigated the background to the formation of the term Hyangjang (香粧), and reviewed the aspects of cosmetic culture that changed with the emergence of Hyangjangpum (香粧品), or cosmetics containing perfume. The investigation revealed that the term Hyangjang (香粧) appeared for the first time in Hirano (1899), a literature published in the Meiji period in Japan, and that the new term Hyangjang (香粧) had been formed against the background of advanced Western synthetic perfume and played an important role in contemporary techniques for the manufacture of cosmetics. The term Hyangjang (香粧) and cosmetics containing perfume, or Hyangjangpum (香粧品) were then introduced from Japan to Korea. In Korea, the term 'Hyangjang (香粧)' appeared for the first time in an advertising copy written by Hyeon Hui-un, a pioneer of the Korean modern theater movement during the period of Japanese colonial rule. At that time, cosmetic companies in Korea and Japan were releasing cosmetic products that contained perfume that stimulated a women's desire to purchase them by emphasizing 'fragrance' in their advertising. Existing public tendencies to regard a fragrant smell from a made-up face as vulgar were changing and the public perception of fragrance were also changing. The appearance of Hyangjangpum (香粧品) indicates that the existing cosmetic culture revolving around visual sense changed into a complex cosmetic culture involving olfaction. This change in culture is significant in that it heralded the direction of future development towards cosmetic culture that uses increase combinations of different senses including touch, taste, and hearing.

Objective: The time to positivity (TTP) of blood culture reflects bacterial load and has been reported to be associated with outcome in bloodstream infections. This study was performed to evaluate the relationship between the TTP of blood culture and the mortality rates associated with sepsis and septic shock according to the site of infection. Methods: We performed a retrospective cohort study on patients with sepsis and septic shock. The rates of blood culture positivity and mortality as well as the relationship between the TTP and 28-day mortality rate were compared among patients with different sites of infection, such as the lungs, abdomen, urogenital tract, and other sites. Results: A total of 2,668 patients were included, and the overall mortality rate was 21.6%. The rates of blood culture positivity and mortality were different among the different infection sites. There was no relationship between the TTP and mortality rates of total, lung, and urogenital infections. Patients with abdominal infections showed a negative correlation between the TTP and 28-day mortality rate. In patients with abdominal infections, a TTP<20 hours was independently associated with 28-day mortality compared with patients with negative blood culture (hazard ratio, 1.73; 95% confidence interval, 1.16-2.58). However, there was no difference in mortality rates of patients with a $TTP{\geq}20$ hours and a negative blood culture. Conclusion: The shorter TTP in patients with abdominal infections in sepsis and septic shock was associated with a higher 28-day mortality rate.
