Product quality and shelf-life effect of sodium lactate (SL) in combined with chitosans with various molecular weights (MW) in low-fat sausages (LFSs) stored at $10^{\circ}C$ were evaluated. LFSs with SL and chitosans had 75-76% moisture, 1-2% fat, and 15.8-17.1% protein with a pH range of 6.3-6.6. Water holding capacity was decreased, but most textural properties were increased with the addition of chitosan with MW of 30-40 kDa. Hunter a (redness) values were also increased with the addition of sodium lactate and chitosans in combination with laccaic acid at the level of 0.05%, resulting in similar Hunter a value of 150 ppm of sodium nitrite. The combination of SL and chitosans slightly extended the shelf-life of LFSs approximately 3-6 days at $10^{\circ}C$, resulting in inhibition the growth of L. monocytogenes and E. coli O157:H7, as compared to the control. However, the inhibition of microbial growth at $10^{\circ}C$ was not as strong as that at $4^{\circ}C$. Thus, the storage temperature should be as low ($<4^{\circ}C$) as possible to have a maximum antimicrobial activity in LFS containing SL and various chitosans.

본 연구는 동충하초 추출물을 PC12 및 BV2 세포에서 인지능력 개선에 대한 효능을 평가하고자 하였다. 동충하초 추출물을 증류수로 추출하여 PC12 및 BV2 세포로 MTT 분석을 통해 세포 생존율을 확인하고 L-glutamate로 유도한 PC12 세포를 통해 세포 보호 효능과 아세틸콜린 함량 및 아세틸콜린에스테아제 활성을 평가하였다. 또한, LPS로 유도한 BV2 세포를 통해 nitric oxide (NO) 및 prostaglandin E2 (PGE2) 생성량 등의 항염증 효능을 측정하고 western blot 분석을 통해 $NK-{\kappa}B$, p38, JNK, caspase-3 등의 단백질 발현량을 확인하였다. 동충하초 추출물은 $200{\mu}g/m{\ell}$ 농도를 제외하고 1, 10, $100({\mu}g/m{\ell})$ 농도에서 세포 독성이 나타나지 않았다. L-glutamate로 유도한 PC12 세포에서 유의성있게 세포 보호 효능과 아세틸콜린 함량의 증가, 아세틸콜린에스테아제 활성 감소가 나타났다. 또한, 동충하초 추출물은 NO 및 PGE2 생성량과 $NK-{\kappa}B$, p38, JNK, caspase-3 등의 단백질 발현을 억제하였다. 이와 같은 결과는 동충하초 추출물이 인지능력에 대한 예방 및 개선 효능이 있음을 나타낸다. 따라서 동충하초 추출물은 인지능력 개선을 위한 새로운 천연 소재로 활용될 수 있다. The aim of this study is to evaluate the efficacy of cordyceps militaris extracts for the improvement of cognitive dysfunction in PC12 and BV2 cells. Cordyceps militaris extracts was prepared by extracting with distilled water. Cell viability was assessed by MTT assay using PC12 cells and BV2 cells. Confirmed effects of L-glutamate induced cytotoxicity test, Acetylcoline (ACh) concentration, and Acetylcolinestase (AChE) activity in PC12 cells. Anti-inflammatory activities of cordyceps militaris extracts was measured through changes in the levels of nitric oxide (NO), and prostaglandin E2 ($PGE_2$) on lipopolysaccharide(LPS)-induced BV2 cell. In addition, we measured the expression of $NF-{\kappa}B$, p38, JNK, and caspase-3 in western blot analysis. Cordyceps militaris extracts showed no cytotoxicity at the concentrations of 1, 10, and $100{\mu}g/m{\ell}$ except for the concentration of $200{\mu}g/m{\ell}$. Cordyceps militaris extracts protected the cell and exhibited significant increases in the ACh concentration and a significant decrease in the AChE activity in L-glutamate induced PC12 cells. Moreover, cordyceps militaris extracts inhibited the productions NO, and PGE2 level and the protein expression of $NF-{\kappa}B$, p38, JNK, caspase-3 in LPS-induced BV2 cells. These results indicate that cordyceps militaris extracts possible prevented and improved cognitive dysfuction symptoms. Thus, cordyceps militaris extracts may be a novel natural material option for the improvement of cognitive dysfunction.

본 연구는 그동안의 공동체 미디어 실천연구들이 전통적 방식의 지상파(전파) 방송에 국한되어 온 것에 대한 문제의식에서 출발하였다. 기존연구들에서 소홀하게 다루어진 온라인 기반 위에서 실천되고 있는 지역 공동체 미디어의 특성과 콘텐츠 제작 및 유통의 특성을 규명하고자 대덕밸리라디오의 사례를 분석하여 다음과 같은 연구결과와 시사점을 얻을 수 있었다. 첫째, 온라인 공동체 미디어 활동은 지역 공동체의 가치를 담아내는 시민미디어(civic/citizen media) 활동이다. 둘째, 미디어 콘텐츠 제작과 유통전략에 따라 퍼블릭 액세스(Public Access)를 통하지 않고도 공동체의 지역성을 실현하는 효과적인 매체 활용을 할 수 있다. 셋째, 온라인 미디어의 콘텐츠는 공동체를 연결하며 개인이 연결점(node)이 되어 온라인과 오프라인에서 상호작용한다. 따라서 본 연구를 통해 온라인 기반 공동체 미디어 실천은 시민들의 미디어 활동의 지속가능성을 높일 수 있는 틈새(니치) 미디어로서 기능할 수 있다는 것을 밝힐 수 있었다. This study started from the consciousness that the community media practice studies have been confined to the traditional terrestrial broadcasting. The following research results and implications were obtained by analyzing Daedeok-valley Radios case to elucidate characteristics of online-based community media and content production and distribution characteristics neglected in previous researches. First, online community media activities are civic/citizen media activities that capture the value of local communities, and this locality is realized through media content production and its online distribution. Second, contents of online community media link members of the community, and individuals become nodes, interacting both online and offline. Therefore, online-based citizen media activities can be utilized effectively as a means to enhance civic participation and to achieve the locality of community in online and offline spaces depending on strategies for online contents production and distribution. Utilizing online infrastructures for media content creation and distribution in Korea demonstrates potential opportunities of local online media to be considered as niche media that can increase its own sustainability.

The result of cleansing hairs using the product after permanent hair dye is given as follows. We can see that contaminations are removed by using white scalp materials and hair dye, rather than by using usual detergents. The results of measuring a color degree using a color meter step in terms of scalp and hairs before and after dye using the product are given as follows. The color degree, L* value, is 43.797, and red and yellow are included very much. However, after dyeing, the color degree of the scalp, L* value, is 29.925; the color of the scalp becomes dark; red is reduced. When we measured the color degree using the scalp cleansing product, the L* value is 37.198; the same color pattern is shown. The scalp has its bright color and is clean; especially the red portion is increased to recover it to its original form. However, there are little different color, comparing with the color before the dye (L* 17.693); the scalp cleansing product increase the brightness (L* 18.144); especially the portion of red is increased. Therefore, the collected results show that after the permanent dye, coloring hair chemicals are not removed after washing, but the specialized scalp cleansing product removes effectively the coloring hair chemicals and remaining.
