Probiotics are functional microorganisms that exhibit various biological activities, such as allergic reactions, inflammation, and aging. The aim of this study is to evaluate the effects of Bifidobacterium lactis CBT BL3 (BL) on the amyloid beta (Aβ)- mediated cognitive impairments. Oral administration of live BL to intracerebroventricularly Aβ-injected mice significantly attenuated short- and long-term memory loss estimated using the Y-maze and Morris water maze tests. We found that expression of apoptosisrelated proteins such as caspase-9, caspase-3, and cleaved poly (ADP-ribose) polymerase was significantly elevated in the brain tissues of Aβ-injected mouse brains when compared to that of the control mouse group. Interestingly, these expression levels were significantly decreased in the brain tissue of mice fed BL for 6 wk. In addition, the abnormal over-phosphorylation of mitogen-activated protein kinases (MAPKs) such as ERK1/2, p38 MAPK, and JNK in the brain tissue of intracerebroventricularly Aβ-injected mice was significantly attenuated by oral administration of BL. Taken together, the results indicate that Aβ-induced cognitive impairment may be ameliorated by the oral administration of BL by controlling the activation of MAPKs/apoptosis in the brain. This study strongly suggests that BL can be developed as a functional probiotic to attenuate Aβ-mediated cognitive deficits.

디지털 기술의 진화에 따라 유무선통합, 음성데이터 통합, 방송통신융합이 구현되는 신규 서비스들이 등장하였고 디지털 컨버전스를 통해 도시의 유비쿼터스화(U-city)가 사회 전반에 걸쳐 진행됨에 따라 IPTV와 같은 융합 서비스가 등장하고, 콘텐츠의 제작방식 및 유통경로가 다양화 되는 등 여러 산업 분야에서 많은 변화가 나타나고 있다. 이에 따라 본 논문에서는 교육, 금융, 공공행정, 쇼핑 등 방송통신융합 서비스를 통해 이용될 수 있는 산업을 조사하고, 방송통신융합 서비스가 이들 산업과 관련된 시장 및 사업자에게 미치는 영향에 대한 가치사슬융합을 분석하였다. 이들 산업들은 방송통신융합 서비스를 통해 더욱 다양하고 혁신적인 내용의 서비스가 제공될 것이며, 이에 따라 창출되는 가치들과 서비스 이용자들의 행태 변화를 예측해보았다.
b-시클로덱스트린(b-Cyclodextrin)과 톨루엔(toluene) 결합특성에 관한 연구

Surfactants, such as -cyclodextrin (-CD), have frequently been used to desorb hydrophobic organic compounds (HOCs) from the soil and to enhance the bioavailability of HOCs. This study was performed to investigate the binding characteristics between toluene and -CD with batch experiment and the column study. The results showed that -CD formed an efficient complex with toluene. As the -CD concentration increased, the amount of toluene complexed with the -CD rapidly increased, up to 40% of the initially added concentration at equilibrium. The effect of -CD on the desorption of toluene from the soil in a water/soil system showed that as the -CD concentration increased, the amount of toluene desorbed into the water increased up to 100% of their initial toluene concentrations. In the column experiment, toluene was effectively transported through the column in the presence of -CD without sorption or retardation.

Different from governmental/government-financed construction projects, private construction projects in North Korea are placed in a complex and specific circumstance, thus being involved with a lot of risks. In this vein, it is necessary to take measures to manage such risk factors, but not many private construction projects in North Korea have been carried out so far and data and preceding studies on its risk management plans could be hardly found. Therefore, the purpose of this study was to examine the risks of private construction projects in North Korea and suggest some risk management plans through some examples. For this, the investigator interviewed with people who were working for constructors and their collaborators, and used data on the training of government officials. Study findings are as follows: 1)from planning to completion, risk factors of construction projects in North Korea were analyzed and measures were presented, centering on the approval of construction, shipping of materials, visiting procedures, stays, on-site construction, and safety supervision. 2) since the risk factors of private construction projects in North Korea are quite different from those of general construction projects, it is necessary to talk over a contract with the said party in North Korea fully in advance. 3) since the construction projects in North Korea are carried out in a specific site with which regular contacts are impossible, thorough advanced preparation is a must in order not to face the risks of cost and time.
