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.

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.

이미현(Mi Hyun Lee),김대연(Dae Yeon Kim),남덕현(Duck Hyun Nam) 한국체육측정평가학회 2012 한국체육측정평가학회지 Vol.14 No.2

본 연구의 목적은 일축가속도계인 GT1M과 삼축가속도계인 GT3X간의 신체활동량 추정에 관한 타당도 평가이다. 연구대상은 서울, 경기 지역에 거주하는 남자를 대상으로 아동은 28명, 성인은 17명으로 임의 표본 추출하였다. 신체활동량은 두 집단 모두 운동강도가 증가함에 따라 VO2, GT1M, 그리고 GT3X의 Activity Counts가 증가하는 것으로 나타났다. 또한, 두 집단에 대하여 동일한 운동강도에 변화량을 주었을 때 성인에 비해 아동의 VO₂와 METs의 변화량이 큰 것으로 나타났으며, GT1M, GT3X의 Activity Counts에 대해서는 낮은 변화폭을 나타냈다. 가속도계와 준거 도구의 신체활동량에 대한 관계를 살펴본 결과, GT1M과 GT3X가속도계의 Activity Counts와 본 연구에 사용된 K4b² 모든 변인에 대하여 통계적으로 유의한 상관이 있는 것으로 나타났으며 아동보다 성인에게서 더 높은 상관이 있는 것으로 나타났다(p<.01). 설명력은 GT1M과 GT3X가속도계 모두 성인(R²=.798, R²=.801)에게서 아동(R²=.550, R²=.522)보다 높은 것으로 나타났다. Bland-Altman Plot에서는 GT3X가 GT1M 보다 편차가 작은 신뢰구간을 나타냈으며, 성인이 아동보다 편차가 작은 신뢰구간을 나타냈다. 대상별에 따른 좀 더 정확한 결과치를 제공 받을 수 있도록 올바른 가속도계의 선택이 요구된다. The purpose of this study is to evaluate the validation of physical activity between GT1M, the uniaxial accelerometer and GT3X, the triaxial accelerometer. For the subject of the study, 28 children and 17 adults were random sampling who are residing in Gyeonggi province. It is observed that as the exercise intensity increases, the physical activity of VO₂, METs, GT1M and GT3X in both groups are increased. Also, when both two groups have given changes to equivalent exercise intensity, the children showed higher VO₂ and METs changes than those of adults while the value of GT1M and GT3X showed lower changes. As a result of observing the relationship between accelerometer and standard tool, activity counts of GT1M and GT3X and all variables of K4b² which were employed in this study showed statistically significant relation, while showed higher relation in adult than in children(p<.01). Both GT1M and GT3X showed higher explanatory power in adult (R<sup>2</sup=.798, R2=.801) than in children (R<sup>2</sup=.550, R²=.522). In Bland-Altman Plot, GT3X showed confidence interval with less deviation than GT1M, while the adult showed confidence interval with less deviation than the children. To provide a more accurate result value, the correct choice of accelerometer according to the sampling is required.
