Objective : This study was to investigate the effects of several herbs on the levels of MT1 and MT2 melatonin receptorsMethods : For this study, we carried out dementia assessment examination of 34 patients with memory disturbance who have come to Cheongju oriental hospital of Daejeon university from April 2005 to February 2006. This study classified the patients as none-dementia(ND), questionable dementia(QD), and dementia(DA) groups and analyzed the result of examination. Results : 1. The water extracts of Dimocarpus long (WEDL) induced the levels of MT2 melatonin receptor expression in a concentration-dependent manner without altering the levels of MT1 melatonin receptor expression. 2. The treatment with the water extract of Zizyphus vulgaris (WEZV) induced the levels of MT1 melatonin receptor expression and the levels of MT2 melatonin receptor expression was not affected. 3. The levels of MT1 as well as MT2 melatonin receptor expression were markedly up-regulated in the water extract of Fossilia ossis (WEFO) and the water extract of Ostreae caro (WEOC)-treated C6 cells. 4. The combination treatment with WEDL and WEZV induced not only the levels of MT1 melatonin receptor expression but also MT2 melatonin receptor expression, but the synergic effects of the combination treatment with WEFO and WEOC were not detected in C6 cells. Conclusion : The study provides important new insights into the possible mechanisms on the regulation of melatonin receptor synthesis by WEDL, WEZV, WEFO and WEOC.

본 연구에서는 제주도에서 채집한 Hizikia fusiformis biochar를 이용하여 수용액 상에서 $Cr^{6+}$과 $As^{3+}$ 중금속의 흡착 특성을 평가하였다. $Cr^{6+}$과 $As^{3+}$ 흡착에 있어서 최적 pH는 각각 pH 2와 pH 6이었다. 동역학적 실험 결과, 대부분의 중금속이 처음 100 min 동안 흡착이 되었으며, 300 min 이후 평형에 도달하였다. 또한, 해초 biochar의 $Cr^{6+}$과 $As^{3+}$ 중금속 흡착은 유사 1차 모델과 2차 모델에서 모두 잘 부합하고 있는 것으로 나타났다. 평형 흡착 실험 결과는 Langmuir 모델에 잘 부합했고, $Cr^{6+}$ (25.91 mg/g)이 $As^{3+}$ (16.54 mg/g)보다 흡착량이 높았다. 본 연구 결과를 통해, 오염된 환경에서 해초 biochar는 $Cr^{6+}$ 및 $As^{3+}$ 중금속의 효과적인 흡착제임을 보였다. This study examined the adsorption characteristics of $Cr^{6+}$ and $As^{3+}$ in the aqueous solution by Hizikia susiformis biochar which was collected from Jeju Island. The optimal pH for $Cr^{6+}$ and $As^{3+}$ adsorption were 2 and pH 6, respectively. Kinetic data showed that the adsorption occurred during the first 100 min, and the most of heavy metals were bound to biochars within 300 min. Moreover, the kinetic data presented that the course of adsorption follows the Pseudo first and second order models. The equilibrium data were well fitted by the Langmuir model and the $Cr^{6+}$ adsorption capacity (25.91 mg/g) was higher than that of $As^{3+}$ (16.54 mg/g). From these results, the seaweed biochar was shown to be a efficient adsorbent for $Cr^{6+}$ and $As^{3+}$ metals in a contaminated environment.

Dynamic range on the digital detector can be a representation to the ratio of maximum and minimum of pixel value. Wide dynamic range and post processing ability of the digital detector made difficult to recognize visually to high or low dose images. We were evaluated a change of mean pixel value on the original and processed image, when we controlled the kVp, mA, exposure time on the digital detector. On the kVp of a constant condition, we were acquired an original and processed image by changes of mA, exposure time. According to the thickness of the subject under the same conditions, to determine a relation of pixel value and X-ray intensity, we used an aluminum step wedge. When mA and exposure times were changed under the kVp of a constant condition, the X-ray intensity was decreased by the reduction of the mean pixel value. In addition when kVp was increased in a constant condition of mAs, the mean pixel value was increased according to the increment of the X-ray intensity. Therefore, low kVp, high mA and short exposure time were a way to reduce a patient dose.

코팅 피치의 물성제어를 통한 흑연 음극재의 전기화학 성능 향상 연구

김보라,김지홍,강석창,임지선,Kim, Bo Ra,Kim, Ji Hong,Kang, Seok Chang,Im, Ji Sun 한국공업화학회 2022 공업화학 Vol.33 No.5

A pitch coating method was proposed for the purpose of improving the electrochemical properties of natural graphite. The synthesis conditions of pitch coating were optimized via measuring electrochemical properties of pitch-coated graphite anodes. As the synthesis temperature increased, the thermal stability was improved in addition to an increase in the softening point and residual carbon weight. However, the synthesis temperature of 430 ℃ resulted in the synthesis of a large amount of NI (NMP Insoluble) due to excessive condensation reaction. As the surface uniformity and coating thickness increased due to high thermal stability, the initial coulombic efficiency and rate capability of the pitch-coated graphite were improved. However, the graphite coated with the pitch containing excessive NI showed lower electrochemical properties than the uncoated graphite. NI had low dispersibility and formed spheres after heat treatment, so it formed the heterogeneous and thicker SEI layer. The optimum conditions for forming a uniform surface and an appropriate coating layer were investigated.

회분식 고강도 광원 처리에 의한 막걸리 효모의 살균

김보라 ( Bo Ra Kim ),김애진 ( Ae Jin Kim ),홍희정 ( Hee Jung Hong ),신정규 ( Jung Kue Shin ) 한국산업식품공학회 2013 산업 식품공학 Vol.17 No.2

UV 파장이 차단된 고강도 광원을 활용한 광펄스 시스템을 이용하여 막걸리로부터 분리한 효모의 살균 효과에 대하여 연구하였다. 광펄스 처리의 주요 변수인 빛의 세기와 처리시간 그리고 frequency에 따른 효모의 사멸 효과를 살펴본 결과 광원의 빛의 세기(전압의 세기)가 높아질수록 그리고 처리시간이 길어질수록 높은 사멸율을 나타내어 1000V, 50 sec 처리 후 모든 균(약 7 log CFU/mL) 이 사멸하였으며, 처리시간에 따라 직선적으로 사멸하는 경향을 보였다. 일정한 빛의 세기와 처리시간에서는 frequency가 증가할수록 사멸 효과가 증가하였지만 실제 처리시간(처리시간×펄스수)이 같으면 frequency에 상관없이 같은 사멸효과를 보여 frequency에 따른 사멸율의 영향은 없었다. 시료내에 초기 균수 농도가 높을수록 투명도의 감소에 의해 광원의 투과력이 떨어져 사멸효과는 감소하였으며, 시료의 깊이가 증가할수록 사멸효과는 감소하여 시료의 깊이가 5 mm이상일 경우 사멸효과가 급격히 떨어졌다. 광펄스 처리 중 시료의 온도는 변화가 없었다. 이상의 결과로 미루어 볼 때 광펄스 처리가 실제 공정에 적용될 경우 온도의 변화없이 시료 내의 미생물을 사멸하는데 효과는 있으나 이를 위해서는 시료의 탁도와 초기균수 그리고 깊이를 고려하여 설계되어야 할 것으로 보인다. Intense pulsed light (IPL) treatment is one of the emerging non-thermal techniques being investigated as an alternative to conventional thermal treatment because it has been proven to be effective for microbial inactivation in air, water, and foods. The aim of this study was to evaluate the possibility of using IPL treatment for the effective inactivation of isolated yeast in makgeolli. The key parameters of intense pulsed light are light intensity (input voltage), treatment time, frequency of pulse, and depth of sample. The results show that there is a significant reduction of population along with an increase of light intensity and IPL treatment duration. The highest level of inactivation achieved in this study was approximately a 7 log CFU/mL reduction. In addition, the inactivation rates of yeast cells decrease with increasing initial cell population and depth of samples. But pulse frequency did not affect the inactivation of yeast. Temperature was not changed during IPL treatment.

As street space is composed of many facilities, behaviors of users should be carefully considered. Most of the past urban facilities were confusing, focusing on economic and functional aspects, but present urban space has actively been engaged to express urban elements considering aesthetic design. At this point when guidelines on public facility installation and standard design have been announced by each local government, it is necessary to evaluate present public facilities.Therefore, this study analysed whether present public facilities which were installed through the past deliberation are suitable for standard guidelines and present public facilities reflect guidelines properly and the results are presented as follows: First, facilities in Gwanju and Jeonnam which have been reorganized based on organized and systematic guidelines have similar shapes, colors and textures, which seems that the degree recommended standards are reflected is low. Second, it is suggested that present guidelines need specific recommendations considering structures, shapes and characteristics of streets targeting hierarchical goals and integrated strategies of public facilities and space. Third, partial replacement and revision of the recommended installation guidelines of each local government are needed for reorganization of public space. Keywords : 교통시설물, 국제행사장, 가이드라인

도서지역 마을공동체사업의 주민참여 특성 및 제약요인 연구

김보라 ( Bo Ra Kim ),강신겸 ( Shin Kyum Kang ) 한국도서학회 2016 韓國島嶼硏究 Vol.28 No.1

본 연구는 도서지역 마을공동체사업에 참여하는 주민들의 참여 특성과 제약요인을 분석하고 개선방향을 제안하는데 있다. 행정자치부‘찾아가고 싶은 섬’으로 선정되어 마을공동체사업이 진행되고 있는 여수시 금오도·안도를 사례로 연구하였다. 인구통계학적 변수에 따른 제약요인 인식 분석에서 거주년도에 따른 제약요인 인식 차이에서 유의한 차이가 있는 것으로 나타났다. 현재 금오도에서 평생 거주 그룹과 귀촌 인구 그룹 간에 갈등, 소득사업, 운영지원 및 인프라 요인에 대한 인식 차이가 존재함을 알 수 있다. 현재 사업 참여 여부 및 참여사업의 유형에 따라 제약요인 인식에서 차이가 있으며, 고령층 주민의 대다수가 사업관련 정보와 네트워크에서 소외되어 있는 것으로 나타났다. 참여동기에 따른 제약요인 인식 차이에서는 참여동기가 ‘소득 향상’이라고 응답한 그룹이 제약요인을 높게 느끼는 것으로 나타났다. 또한 향후 사업 참여의향이 있는 집단이 그렇지 않은 집단보다 제약요인을 높게 느끼는 것으로 나타났다. 이는 마을공동체사업 참여함에 있어 소득향상이 주민들의 실질적 이익을 가져다주는 것을 고려할 때, 적극적으로 참여한 그룹일수록 각 요인들을 큰 제약요인으로 느끼며, 개선할 필요성이 있다고 판단하고 있다. IPA분석을 통해 도서지역 마을공동체사업 진행에 따른 제약요인과 개선시급성 분석을 실시한 결과, 개선 당면 과제는 관광편의시설, 정부예산지원을 확대하는 것이며, 주민교육과 주민의견 수렴 확대, 전문가 컨설팅 확대 등으로 나타났다. 이러한 분석을 바탕으로 도서지역 마을공동체 사업의 개선을 위해서는 지자체와 중간지원 조직, 그리고주민과의 끊임없는 소통과 의견교환이 이루어지는 상호작용적 시스템구축이 필요함을 제안하였다. The purpose of this study is to analyze the constraint factors associated with the participation characteristics of residents in the process of project implementation among the local residents who participated in the community business development project of Geumo-island and An-island. Also, this study aimed to propose improvement direction and vitalization measures in relation to the constraint factors. The empirical analysis showed the following results. There was a significant difference in the recognition of constraint factors depending on residence period. One of the issues is a conflict between the local resident group and the returnee group. Also, the constraint factors of participation community business and participation motivation differed significantly. This was mainly caused by the fact that the elderly people within the villages were alienated from business related information and network. The group showed willingness to participate in the constraint factors that depended on participation intention. By using IPA analysis, this study analyzed the constraint factors and improvement emergency through conducting a village community business in the island area. The IPA results were classified into the 4 following items. The imminent tasks for improvement are tourist facilities, government support, business model, resident training and consultation. In order to improve the community business in the island area, it is definitely required to build an interactive system that allows continuous communication with local governments, mid-level support organizations and local residents.
