This study aimed to investigate the changes in antioxidant activities, quality characteristics, and storage stability of mayonnaise prepared with perilla oil with the addition of mulberry powder ranging from 0 to 5%. The antioxidant activities of perilla oil mayonnaise (PM), as determined by DPPH and ABTS radical scavenging activity, as well as FRAP and total phenolics content were improved by the addition of mulberry powder compared with the control sample. Antioxidant activities were dependent on the amount of mulberry powder added. Lipid oxidation of PM decreased with a higher amount of mulberry powder, based on measurements of peroxide value. The emulsion stability of PM increased with decreases in the amount of mulberry powder level. The a-value in PM color increased with increasing amount of mulberry powder. Sensory evaluation showed that the highest score in overall acceptability of PM was achieved with 4% mulberry.

Purpose: To compare the efficacies of photodynamic therapy (PDT) using verteporfin combined with intravitreal bevacizumab in choroidal neovascularization secondary to age-related macular degeneration and polypoidal choroidal vasculopathy (PCV). Methods: Photodynamic therapy followed by 3 monthly intravitreal injections of bevacizumab were performed for neovascular age-related macular degeneration (AMD group) and PCV (PCV group). The injections were performed within 2 weeks after PDT and then every 4 to 6 weeks. During the 12-month follow-up period, best-corrected visual acuity (BCVA), central subfield macular thickness (CSMT), and number of reinjections were reviewed retrospectively. Results: Out of 38 eyes, there were 21 eyes in the AMD group (mean age 66.8 years old) and 17 eyes in the PCV group (mean age 66.4 years old). The average follow-up duration was 17.0 months. At 12 months, the BCVA (logMAR) improved from 0.75 at baseline to 0.49 in the AMD group (p = 0.01) and from 0.81 to 0.63 in the PCV group (p = 0.03). The CSMT decreased significantly from 329 to 231 in the AMD group and from 354 to 223 in the PCV group. At 12 months, 20 eyes (95.2%) in the AMD group and 15 eyes (88.2%) in the PCV group increased or maintained BCVA. The numbers of reinjections were 4.3 in the AMD group and 3.0 in the PCV group. There were no significant differences in BCVA, BCVA changes, CSMT, or number of reinjection between the two groups. Conclusions: Combined PDT and intravitreal bevacizumab injections showed no significant difference in stabilization of vision or retreatment rates between neovascular age-related macular degeneration and PCV.

물질주의 가치관에 따른 청소년의 의복행동에 관한 연구

이미현 배화여자대학 2002 培花論叢 Vol.21 No.-

This study deals with the teenagers who take high interest in fashion and their appearances while being susceptible to the influences of their authoritative figures and/or the society due to their psychological instability, and is aimed at verifying if their psychologically variable sense of value has any affect on their clothing behavior in the midst of the consumption-orientated sociological environment where the traditional sense of value had crumbled away and is now surged with materialistic values. The study results showed that the teenagers materialistic tendency are related to their family environments: such as family financial status and forms, age, education background and occupation of their parents, and their monthly allowance and clothing expenses. Since it showed that teenagers materialistic sense of value is higher when their family is of low financial status, nuclear family, young parents with low education background, and if they spend more allowance and clothing expenses, it is second-handedly surmised that younger parents who are not financially stable are more inclined to be materialistic and their children are also influenced by such parents. Materialistic sense of value influences the teenagers clothing behaviors, so that the teenagers with higher materialistic values pay more attention to esthetics when they dress and have higher interest and dependency on clothing compared to the teenagers who are less inclined to materialistic sense of value. Also they have higher tendencies to dress similarly with their peers and show off through their clothes. However, they don't seem to care much for decency when they dress. Materialistic sense of value also influences on teenagers shopping for clothes. Buying motivations of teenagers with higher materialistic sense of value are more impulsive and ostentatious than that of the teenagers with lower materialistic sense of value, whereas their practical or essential buying motivations are relatively lower. Even their sources of information and favorite places for shopping showed difference: teenagers with higher materialistic sense of value facilitate more sources of information and various places to shop, and purchase expensive clothes more frequently while spending much time for shopping. In view of such results, teenagers materialistic sense of value influence considerably on their interests in clothes, dressing and shopping.

민들레 [Taraxacum platycarpum]유식물 절편으로부터 부정아 발생에 미치는 auxin과 cytokinin의 영향 및 식물체 재생

이미현,윤의수,정수진,배기화,서진욱,최용의,Lee, Mi-Hyun,Yoon, Eui-Soo,Jung, Su-Jin,Bae, Ki-Hwa,Seo, Jin-Wook,Choi, Youg-Eui 한국식물생명공학회 2002 식물생명공학회지 Vol.29 No.2

민들레 (Taraxacum platycarpum)는 오래전부터 민간에서 약용으로 이용되어 왔다. 본 실험에서는 민들레로부터 효율적인 식물체 재분화 조건을 조사하기 위해 수행되었다. 부정아 유도에 있어서 적절한 생장조절제와 그 농도를 조사하기 위하여 auxin (2.4-D, NAA) 또는 cytokinin (BAP, kinetin, 2-ip)을 단독, 조합처리 하였다. Cytokinin 단독 혹은 auxin과 조합처리시 부정아가 유도되었는데 이 중 2mg/L BAP에서 가장 높게 나타났다. Cytokinin 단독처리시 종류에 따라 부위별 부정아 형성률이 다르게 나타나며, 민들레의 경우에는 특이하게 뿌리 절편에서 자엽과 배축 절편보다에서 부정아 형성률이 가장 높게 나타났다. 한편 auxin을 cytokinin과 조합처리한 경우에는 cytokinin 단독처리시보다 뿌리 절편에서 부정아 형성률이 급격히 떨어졌다. 반면 자엽 부위로부터 부정아 형성률은 크게 증가되었다. 부정아로부터 부정근의 유도는 0.2mg/L NAA에서 가장 양호하게 나타났으며 인공배양토의 순화과정에서 93%의 높은 생존율을 보였다. 비무균상태의 마사토에서 100%생존함으로써 기외의 포장이식에 어려움이 없을 것으로 생각된다. Taraxacum platycarpum has been used as a medicinal plant. We investigated optimal condition for efficient plant regeneration through adventitious shoot formation on medium with various kinds of growth regulators. Adventitious shoot formation was achieved when cytokinin was used alone. Shoot formation was higher on MS medium containing 2 mg/L BAP compared to that with 2 mg/L kinetin and 2 mg/L 2-ip. Among root, hypocotyl and cotyledon, roots were the best explant for the adventitious shoot induction. Adventitious shoot formation from roots declined markedly by the combination of both 0.1 mg/L NAA and 2 mg/L BAP, while shoot formation from cotyledons was stimulated by the same combination. Root formation from the regenerated shoots was achieved on 1/3MS medium containing 0.2 mg/L NAA. Regenerated plantlets was acclimatized and transplanted to the soil, showing 100% survival.

목적: 원추각막의 정도에 따른 Pentacam(R)의 각막 전, 후면의 융기 및 시상면만곡도의 변화와 정상안과 차이를 알아보고자 한다. 대상과 방법: 원추각막 81안과 정상 20안을 대상으로 Pentacam(R)을 촬영하였다. 원추각막안은 각막굴절률 평균값에 따라 경도(≤47diopter (D)), 중등도(47-52D), 중증(≥52D)으로 나누고, 각막두께, 굴절률, 각막 전, 후면 융기와 시상면만곡도를 측정하고 정상안과원추각막의 연관성을 조사하였다. 결과: 원추각막 81안 중 경도 56안, 중등도 12안, 중증 13안이었고, 평균 각막중심굴절력은 49.7D, 각막 전, 후면 융기는 22.07 μm, 38.16 μm, 시상면만곡도는 52.76D으로 정상안에 비해 유의하게 증가하였고, 원추각막의 정도가 심할수록 증가하였다. ROC 커브 분석으로 각막 전, 후면의 융기와 시상면만곡도에서 원추각막의 진단을 위한 의미 있는 수치를 얻었다. 결론: 원추각막의 Pentacam(R) 수치가 각막 전, 후면 융기가 각각 5.5 μm, 12.5 μm이고, 시상면만곡도가 44.5D일 때, 원추각막의 확진에 도움이 되며, 원추각막의 진행을 평가하는 데도 기여할 것으로 생각한다. Purpose: To compare changes of anterior and posterior corneal elevation, and sagittal curvature according to the severity of keratoconus and to compare differences between keratoconus and normal cornea. Methods: A total of 81 eyes diagnosed with keratoconus and 20 eyes of normal subjects were evaluated with a Pentacam Scheimpflug camera. The keratoconus eyes were divided into 3 groups according to mean keratometer (K): mild (K ≤ 47.0 diopters (D)), moderate (47.0 to 52.0 D), and severe (52.0 D≥). The following parameters were obtained to evaluate the correlation of keratoconus: corneal thickness, anterior and posterior corneal elevation, and sagittal curvature. Results: Out of 81 keratoconus eyes, 56 eyes were mild, 12 eyes were moderate, and 13 eyes were severe keratoconus. The mean central corneal keratometer, anterior and posterior corneal elevation, and sagittal curvature of the keratoconus eyes were 49.7 D, 22.07 μm, 38.16 μm, 52.76 D and the values increased statistically compared to the normal eyes. Furthermore, the values increased significantly with the severity of keratoconus. ROC curve analysis showed the estimated meaningful value for anterior and posterior corneal elevation and sagittal curvature of keratoconus for diagnosis; there were no diagnostic values for corneal thickness and refractive power. Conclusions: The index of 5.5 μm for mean anterior elevation, 12.5 μm for mean posterior elevation, and 44.5 μm for mean sagittal curvature using the Pentacam(R) are useful to diagnose keratoconus. Variation of anterior and posterior elevation, and sagittal curvature measured by Pentacam(R) are useful in understanding the process of keratoconus. J Korean Ophthalmol Soc 2012;53(10):1432-1437

이미현 ( Mi Hyun Lee ) 대한미용문화예술학회 2013 대한미용문화예술학회지 Vol.2 No.2

This study examines college girls` knowledge about skin and their skin care habit based on the college girls who have just started make up in earnest and are very interested in skin care. According to the findings of this study, college girls are very interested in their own skin and they self-examine their own skin types to the high level and they exert individual great effort to solve skin problems. However, their knowledge about skin care method is unprofessional knowledge. And it seems that though they have knowledge about skin care, they don`t make a habit of caring skin because of economic reason and so on. In college girls` health status and behaviors, the drinking and smoking rates are high while they lack exercise. Thus they should pay attention to the skin problem due to health condition. Therefore, we need to develop education programs about effective skin care consistently so that college girls who are very sensitive about their appearance and skin can improve knowledge related to skin and care their skin effectively. College girls can raise their sense of self-respect after they solve their skin problems by learning professional knowledge of skin care suitable for their skin types through this education.
