Plant growth promoting (PGP) hormones, which are produced in a small quantity by bacteria, affect in plant growth and development. PGPs play an important role on the crop productivity in agricultural field. In this study, a photosynthetic bacterial strain producing the PGP was isolated from paddy soil. Bacterial isolate was gram negative, rod-shaped and motility positive. From the 16s rRNA gene sequence analysis, the isolate was identified as Rhodobacter capsulatus PS-2. The mass cultivation of R. capsulatus PS-2 was optimized by considering of the carbon, nitrogen and inorganic salt sources. Optimal medium composition was determined as Na-succinate 4.5 g, yeast extract 5 g, $K_2HPO_4$ 1 g, $MgSO_4$ 5 g, per liter. From the result of 500 L fermentation for 2 days using the optimal medium, the viable cells were $8.7{\times}10^9cfu/mL$. R. capsulatus PS-2 strain produced the carotenoid and indole-3-acetic acid (IAA). The carotenoid extraction and quantitative analysis were performed by HCl-assisting method. Total carotenoid contents from R. capsulatus PS-2 culture broth were measured as $7.02{\pm}0.04$ and $6.93{\pm}0.05mg/L$ under photoheterotrophic and chemoheterotrophic conditions, respectively. To measure the productivity of IAA, colorimetric method was employed using Salkowski reagent at optical density 535 nm. The results showed that the highest content of IAA was $197.44{\pm}5.92mg/L$ in the optimal medium supplemented with 0.3% tryptophan.

DA-3711 is a novel anti-wrinkle agent containing growth factors derived from culture medium of artificial human skin. Photoprotective effect by DA-3711 against chronic UVB (ultraviolet B)-induced skin damage was investigated in hairless mice model. Methods: After hairless mice were irradiated to induce photodamage for 8 weeks with UVB, grouped mice were treated topically once a day with lotion base, DA-3711 (30% or l5%), Cylasphere retinol$^{\circed{R}}$ (2500 I.U.), NouriCel$^{\circed{R}}$ along with concomitant exposure to UVB for further 8 weeks. Then mice were sacrificed to assess photodamage-protective effect by replica analysis, biochemistry and histology. DA-3711 of 30% lotion significantly reduced UVB radiation-induced wrinkling, histological alterations and increased collagen contents. Whereas DA-3711 of l5% lotion and NouriCel$^{\circed{R}}$ treatment showed a partial protective effect on skin wrinkle, epidermal and dermal thickness, and collagen content, Cylasphere retinol$^{\circed{R}}$ showed no protective effects. These results demonstrate that topical application of DA-3711 can alleviate UVB-induced photodamage and potentially be used for reduction of UVB-induced photodamage.

An experiment was conducted to examine the effects of Kalopanax pictus Nakai (Kalopanax) on in vitro rumen fermentation and methane (CH4) reduction. Kalopanax trunk was extracted with 70% ethanol and 70% methanol. Rumen fluid, alfalfa hay and buffer (control: C) supplemented with 0.3% Kalopanx juice (T1), 0.3% ethanol extract (T2) and 0.3% methanol extract (T3) in the total volume of culture medium were incubated at $38^{\circ}C$ for 24h and 48h. Rumen pH was lower in all Kalopanax treatments during all incubations than that in control (p<0.05). Total VFA and total gas production in T2 and T3 was significantly higher than that in C at 48h incubation (p<0.05). Ammonia-N was decreased in all treatments compared with C during the incubation periods (p<0.05). At 24h incubation, $CH_4$ contents were significantly reduced by both alcohol extracts. It is concluded that supplementing Kalopanax extracts can stimulate ruminal fermentation of rumen microorganisms and inhibit methanogenesis.

Background : Demands have increased for a variety of welfare services and customized services for persons with disabilities(PWD). A management System focused on PWD was needed to provide for comprehensive services. The purpose of this study was to design a disability database and an application system in order to provide continuous and comprehensive rehabilitation service for PWD. Methods : We analyzed local and abroad disability-related policies and systems and derived the contents that should be included in the integrated database for PWD through a survey among rehabilitation specialists. Result : The integrated database for PWD was composed of 7 categories including General Characteristics, Health & Medicine, Assistance, Education, Employment, Economics and Daily & Social Life. The applicable system of integrated database for PWD was proposed to help conducting policies in such areas as follows ; 'welfare', 'education and culture', 'economic activity', 'social participation' and 'Health'. Conclusion : The main goal of disability policy and strategy should be established by systematically analyzing disability-related data integrating database of PWD. Accordingly, specific objectives and directions for disability policies should be set and efficiently managed and operated. The integrated database for PWD may be utilized for disability-related policies and service monitering, sustainable and integrated management and community participation and integration based on the rights of the disabled.

The purpose of this study is research on the characteristics of post-modernism expressed on western hair styles in the late 20th century. Therefore this thesis analyzed the relationship of modernism & the hair styles of that mage and post-modernism & the hair styles of that mage. That will re-illuminate the same beauty worth of same age as to accurate the concept of post-modernism & the hair styles of that mage. And the last, criticizing the post-modernism design and that hair design, helping to find new trends. The method of this study was the literature research & analysis of visual materials focus on upper bust image that can know the relationship of modernism & the hair styles of that mage, and post-modernism & the hair styles of that mage. First, the literature research is composed of analysis of theses, magazines on art, clothing and cosmetology having the contents of 20th century western culture, art and hair styles. Second, the analysis of visual materials is composed of analysis of video films, slide films and photographs of books, magazines, and internet home-pages. Modern western hair styles, appeared after 1910's, is represented as a short cut & permanent wave. That express experimentalism, functionalism, and purism, that is same as the other art's trend of same age. Post-modern western hair styles, appeared after 1960's, also show the same trend with same age's. This summarized & characterized 8 categories; historical method, pluralism, negotiation, escape from the formality, recovery of humanity, ornament, connection with race, metaphor & symbolism. But post-modernism concentrating pluralism makes easy making low quality art and absence of criticism, so this thesis criticised it 5 categories; absence of ideas, absence of the social sense of responsibility, lost of one's characteristics, decline of skills, decline of worth of usages.

This study was conducted to investigate the effects on chemical properties of soil and yield of chinese cabbage when the piggery liquid slurry (ADS) digested anaerobically in the biogas plant was sprinkled to the soils. Treatments were composed of non-nitrogen plot (PK), chemical fertilizer plot (NPK) and ADS plot, and were arranged by randomized block design with 3 replications. The ADS was an alkali (pH 8.6) fertilizer containing 0.55% of total nitrogen, optimal levels of phosphorus, potassium and other components. When based (100%) on the yield of chinese cabbage in the NPK, those of the ADS and the PK were 114% and 43%, respectively. The nitrogen absorption of chinese cabbage at 50-d after transplant was significantly greater (p<0.05) in the ADS than other treatment. Heavy metal contents of soil were not difference between before and after experiment. With supplementing phosphorus and potassium sources in it, the ADS should be an excellent fertilizer in cabbage culture.

Generally, human eye blinks are closely associated with the cognitive state or visual attention such as attentional requirements on visual stimuli. These previous studies have reported that eye blinks are related to explicit visual attention using blink rate, pattern and blink timing across subjects. However, these results have been obtained in a well-controlled experimental settings. So, it would prove difficult to investigate human's natural response in a continuous and realistic situation. In our study, we measured the eye blink intervals while participants viewed a movie clip. And we analyzed the blink interval data for relationship between visual attention and eye blink intervals. 24 participants took part in two experimental sessions, first session to measure the IEBI while viewing the movie clip and second session to conduct a memory performance test using a self-questionnaire, which were spaced 3 weeks apart. The results indicate significantly higher memory performance at long IEBI period than short IEBI period while watching a movie clip(t = 3.257, df = 17, p < 0.005, 2-tailed). In addition, memory performance score significantly correlated with the IEBI value(spearman's rho = 0.40, N = 36, p < 0.01, 2-tailed). Our results suggest that IEBI is used to measure or assess visual attention while wiewing the movie that it is capable of simulating aspects of real-life experiences by visual attention. Thus, we expect IEBI to be used to measure or assess our visual attention, cognition, further emotion about not only movies, advertisements and other cultural contents but also cognitive science.
