배트 염료를 이용한 메타아라미드 직물의 염색성 및 견뢰도
김미리,이정진,Kim, Mi Ri,Lee, Jung Jin 한국섬유공학회 2013 한국섬유공학회지 Vol.50 No.6
Herein, 100% meta-aramid woven fabric was dyed with three vat dyes and their dyeing and fastness properties were investigated. Color yields of the vat dyes on the meta-aramid fabric were dependent on dyeing temperature, amount of reducing agent, and amount of salt. Dyeing behavior of the vat dye on the meta-aramid fiber was very similar to that on cellulose fibers. It was found that the meta-aramid fabric dyed with 1% owf of Indanthren Black 5589 satisfied the tolerance of the NIR reflectance spectrum of charcoal color in the Korean military standard. Wash and perspiration fastness was generally good, while rubbing fastness was moderate and light fastness was unsatisfactory.

The purpose of this study was to evaluate of black carrot on the antioxidant activity and quality characteristics of Sulgidduk. Sulgidduk was prepared with different amounts (0, 1, 2, 3, 4%) of black carrot. As the amount of added black carrot increased, the moisture content (p<0.05) and pH were decreased (p<0.001). Sugar content results showed the increase with the addition of black carrot (p<0.01). L (lightness) values and b (yellowness) values decreased whereas a (redness) values increased with an increased concentration of black carrot powder (p<0.001). The mechanical texture of Sulgidduk was decreased by the addition of black carrot considering hardness, chewiness and gumminess (p<0.001) while those of springiness, cohesiveness increased. Consumer acceptability test revealed that the 2% black carrot groups had a higher score than the other groups in respect to color, flavor, taste, texture, overall palatability. To examine antioxidant activities of Sulgidduk, total phenolic, DPPH radical scavenging activity, and total anthocyanin were tested. Total phenolic, DPPH radical scavenging activity, and total anthocyanin showed good vitality as amounts of black carrot powder increased (p<0.001). Based on the various aspects of results, 2% of black carrot added into Sulgidduk showed the best functionality and sensory qualities.

도로건설사업 시 지형 훼손 최소화를 위한 절·성토 높이 기준 연구
김미리,김수련,신지훈,성현찬,Kim, Mi-Ri,Kim, Su-Ryeon,Shin, Ji-Hoon,Sung, Hyun-Chan 한국조경학회 2014 韓國造景學會誌 Vol.42 No.1
본 연구의 목적은 경기도 도로건설사업의 환경영향평가서를 대상으로 도로 건설시 절 성토 높이와 비탈면 높이와의 관계를 분석하고, 도로 건설사업 시 지형적 훼손을 최소화할 수 있는 합리적인 비탈면 높이 기준을 제시하는 데에 있다. 이를 위해 도로건설사업 환경영향평가서 내 비탈면 높이와 관련된 전문가 의견이 제시된 44개의 사례를 검토하고, 그 중에서 절 성토고 높이에 관해 언급된 23개의 사례를 추출하여 분석에 활용하였다. 본 연구의 결과를 요약하면 다음과 같다. 환경영향평가서 상에 제시된 대부분의 절 성토 높이 및 비탈면 높이는 기준 높이인 20~30m(성토 높이), 그리고 10~15m(절토 높이)를 초과하고 있으며, 도로변의 절 성토 높이가 비탈면의 높이와 높은 상관관계가 있다는 것을 보여주고 있다. 그리고 회귀분석 결과에 따르면 각각의 절 성토 높이는 절토 높이의 경우 25.33~33.23m, 성토 높이의 경우 14.56~18.08m로 나타났으며, 이러한 높이 기준은 일반적인 높이 기준보다 높은 것으로 나타나, 향후 환경영향평가서 검토 시에 충분히 고려되어야할 사항으로 판단된다. 본 연구는 환경영향평가서에 제시된 절 성토 높이 및 비탈면 높이만을 고려하고 있어, 실제 제안된 높이가 지형 훼손을 최소화할 수 있는지에 대한 검증은 불가능하였으며, 따라서 본 연구에서 제시된 높이 기준을 바탕으로 비탈면 높이에 대한 친환경성 검증을 위한 심층적인 연구가 진행될 필요가 있다. The purpose of this study is to analyze the relationship between height of cutting and filling as well as the height of slope of roadsides. It also suggests the rational height of slope to minimize topographical damage in road construction. Hence, in this study, 44 cases of expert's opinions related to height of slope in Environmental Impact Assessment(EIA) for road construction projects are reviewed, and 23 cases of data related to height of cutting and filling in EIA for road construction projects are used for analyzing relationship between height of slopes and height of cutting or filling of roadside. The results are as follows; Most of heights of cutting, filling and slope in EIA for road construction are over the required standards 20 or 30m(in case of cutting) and 10 or 15m(in case of filling). It also shows that there is high-level correlation between height of cutting and filling and height of slope of roadside. According to regression analysis, it is suggested that the general standard of each heights of cutting and filling are 25.33~33.23m(in case of cutting) and 14.56~18.08m(in case of filling), but it should be considered in EIA review for road construction projects that these heights suggested in this study are over the required standards.

PDGF-BB와 IGF-I 혼합 투여가 비글견 인공 치근단 병소의 치유에 미치는 영향에 관한 연구
김미리,김민겸,윤수한,Kim, Mi-Ri,Kim, Min-Kyum,Yoon, Soo-Han 대한치과보존학회 2000 Restorative Dentistry & Endodontics Vol.25 No.1
It is difficult to treat the endodontic apical perforation successfully. In this study, we hypothesized that the application of PDGF-BB and IGF-I into periapical perforation site may accelerate periapical healing and lead to bone deposition. And the specificity of osteonectin in periapical healing was investigated. The experiments were performed on the upper and lower 51 premolar teeth of 4 beagle dogs. The pulp chamber of each tooth was opened and the dental plaque was inserted into the canal for developing the periapical lesion for 5 weeks. Then, the roots were artificially perforated at the apex with the number 4 profile of .06 taper. In each step, standard periapical radiographs were taken to compare the size of lesion each other. The radiographs were scanned and analyzed by image analysis system. The mean and standard deviation of periradicular radiolucency ratios were calculated in each group. ANOVA was used for comparison. 51 premolars were grouped into 3 groups; control group, calcium hydroxide-treated group and calcium hydroxide plus growth factors-treated group. In the control group, the apical perforations were not sealed and obturated with gutta-percha and ZOE sealer by lateral condensation technique. In the experimental groups, the apical perforation were sealed with calcium hydroxide and with/without $4{\mu}g$ of PDGF-BB & IGF-I in cellulose gel and obturated by lateral condensation technique. Fluorescent bone markers were used to measure new bone formation. Following 2, 4, 12 weeks after experiment the dogs were sacrificed and histologic sections were prepared. Each tooth block including periapical lesion was sectioned mesiodistally. One half of the sections were decalcified with 6% nitric acid and processed by standard paraffin embedding technique. The sections were stained by hematoxylin and eosin, and immunostained for osteonectin. Histomorphometrical measurement of neoformed bone was performed using a light microscope. And the other half of the sections were prepared by undecalcified preparation, and confocal laser scanning microscopic investigations were done.

COVID-19 led to an increased need for mountainous urban parks in the city that can be enjoyed while moving rather than staying put. However, studies on the economic value of mountainous urban parks have been insufficient. As a result, this study investigates the economic value of Gyeyangsan, a mountainous urban park located in the city, by quantifying the value of natural resources provided to residents and analyzing the factors affecting these values. The results are summarized below. First, according to the economic value assessment of Gyeyangsan, the use value was 2,210 won per person or 4.42 billion won per year, and the preservation value was 6,182 won per household, or 129.37 billion won. Gyeyangsan's total assets value was assessed as 3.68 trillion won. Second, according to the estimates of the willingness to pay and the determinants for the use-value, the frequency of visits, age, and use satisfaction significantly impacted the intention to pay for the use-value. Third, according to the estimates of the willingness to pay and the determinants for the preservation value, the intention to revisit, volunteer participation, educational level, gender, and residence significantly influenced the intention to pay for the preservation value. According to the findings of this study, it will be possible to make crucial policy implications when setting a direction for future park management by presenting a practical policy plan for the maintenance of mountain parks in downtown areas and will broaden the scope of research.
