This paper presents the test results of biological aerated filtration(BAF) process to replace activated sludge process by enhancing treated effluent quality and reducing the costs. In BAF process both BOD and SS compounds in wastewater are degraded and removed by biological reaction and filtration. Upflow BAF with expanded polypropylene media and downflow BAF with ceramic media were used to investigate the effects of hydraulic and organic loads on effluent quality. As a result, in BAF processes which has different media, upflow BAF reactor shows 5% higher efficiency than downflow BAF and this phenomena caused by backwashing methods and operational conditions. The results of influence factors analyzed by Factor Analysis Method in BOD and SS treatment efficiency are the size of media, hight of media bed and type of media. The quantitative effects of media size are 5.73% in TBOD, 5.78% in SBOD and 7.65% in TSS, so we confirmed the main factor is media size.

Objectives : The aim of the present study is to evaluate the wound healing-enhancing and anti-inflammatory effects of Pinus densiflora, Cornus officinalis, Zingiber officinale, Ganoderma japonicum and Scutellaria baikalensison human keratinocyte, HaCaT cells. Methods : We adopted in vitro wound healing assay to measure the proliferation-and migration-enhancing effects in HaCaT cells. The expressions of cytokine genes were measured in HaCaT cells using real-time PCR analysis. Results : The extracts of Pinus densiflora, Cornus officinalis, Zingiber officinale, Ganoderma japonicum and Scutellaria baikalensis enhanced the proliferation and migration of HaCaTcells. The expression of keratinocyte growth factor receptor(FGFR2-IIIb) gene was also induced. The extracts inhibited iNOS, IL-$1{\beta}$ and TNF-$\alpha$ gene expression. Conclusions : The extract of Pinus densiflora, Cornus officinalis, Zingiber officinale, Ganoderma japonicum and Scutellaria baikalensis has wound healing-enhancing effects and anti-inflammatory effects.

Objectives : The study was performed to evaluate a traditional Korean Medicine content in drama "Daejanggeum". Methods : One hundred sixty-nine participants in Taiwan responded to the survey with 10 items, regarding components of success of drama "Daejanggeum". Principal component factor analysis and multiple regression analysis were performed to identify the possible factors to satisfaction with watching drama "Daejanggeum". Results : Factor analysis revealed that dramatic factor(44.8%), content factor(12.3%), and cultural factor(11.3%) were the most important factors to success of drama "Daejanggeum". Multiple regression analysis showed that dramatic factor(beta = .342), content factor(beta = .278), and cultural factor(beta = .131) were associated with the satisfaction with watching drama "Daejanggeum"($R^2$ = .394, with F = 32.280, p<.001). Conclusions : This study demonstrated that dramatic factor, content factor, and cultural factor are the most important factors associated with satisfaction with drama "Daejanggeum" in Taiwan. These findings suggest that a traditional Korean Medicine as a content factor would be very influential in enhancing the possibility of success of drama.

This study was performed to compare in vitro immune enhancing effects of polysaccharides extracted from cultivated mycelia of Agaricus blazei Murill. Carbohydrate contents of semi-purified polysaccharides were 85.6% and 95.3%, while ${\beta}$-glucan conents were 67.9% and 88.1% for intracellular and extracellular polysaccharide, respectively. Samples were adjusted to the same in their carbohydrate contents before efficacy tests. Both intracellular and extracellular polysaccharide increased nitric oxide (NO) synthesis of macrophage RAW 264.7 in dose dependent manner, and the maximum increase rate was 53.9 and 53.1% in intracellular and extraceltular polysaccharide, respectively. The polysaccharides also increased synthesis of cytokines such as interleukin (IL)-$1{\beta}$, IL-6 and tumor necrosis factor (TNF)-${\alpha}$ in RAW 264.7. For all the 3 cytokines, the increase rate of synthesis was much higher in extracellular polysaccharide compared to intracellular polysaccharide, especially at low concentration. Both polysaccarides increased the proliferation of splenocytes in vitro, intracellular polysaccharide showed increase in dose dependent manner while extraceltular polysaccharide showed increase untill medium concentration ($250\;{\mu}g/ml$). They did not show direct cytotoxicity against cancer cells such as B16F0 melanoma. As results, it was regarded that the both intracellular and extracellular polysaccharide from A. blazei showed immune enhancing effects in vitro, but the activity is higher in extracellular polysaccharide compared to intracellular polysaccharide.

The expansion on the scale of international trade and rapid economic growth in Northeast Asia have caused intense competition among global companies for securing international logistics center in Northeast Asia. Analyzing location competitiveness for international logistics center in Northeast Asia, this paper aims to extract implications for enhancing locational competitiveness. Employing the relative importance among location selection factors extracted from AHP analysis in prior study, we evaluated the major five port-cities in Northeast Asia including Busan, Gwangyang, Shanghai, Qingdao and Tokyo. In the evaluations, Shanghai (3.926) ranked as the first, followed by Busan (3.859), Qingdao (3.555), Tokyo (3.013) and Gwangyang (2.915). Furthermore, the causal relationships between determinants for location choice decision (logistics factor, cost factor, market factor, service factor and environmental factor) and dependent variables (competitiveness of international logistics center, potentiality to growth, present intention to move into and future plan to move into) were analyzed to provide implications. Results provide useful insights for further improvements, and helps strategic agenda for future development of port-cities.

The purpose of this study was to find out the dance sports athlete's factor that presents performance problems and performance enhancing for competitions. To achieve purpose of study carried out open-ended question and structural inquiry of succession in the dance sports athlete of 25 people, the open-ended questions data were examined through inductive content analysis procedure, conducted preliminary investigation to 100 people. Preliminary investigation and main survey were verified to the dance sports athlete of 137 people through exploratory factor analysis, and confirmatory factor analysis was conducted. On the basis of the results, the conclusions were drawn as follows; First, hinders factors to athletic performance is discord with partner, condition, contest environment, limit of physical strength, limit of economic strength. Second, the measurement scale of dance sports athlete's performance enhancing to competition with 23 items which are consisted of 7 main factors. The determination factors of dance sports athlete performance were partnership, ability to invest, spiritual factors, training factors, ability of physical factors, the leader, environment of competition.

A combinatorial library of artificial transcription factors (ATFs) was introduced into the bacterial cells that expressed the Akt1-GFP fusion protein. By measuring the level of fluorescence generated by the transformed E. coli cells, we were able to obtain clones in which ATFs increased the solubility of the Akt1. Our results show that ATF library is a useful tool for increasing the solubility of selected recombinant proteins in E. coli.
