본 연구에서는 점차 확대되고 있는 애완학습곤충 시장을 올바르게 이해하고 적절한 대응을 하기 위해 실제 소비자들의 이용행태를 모니터링 함으로써 소비자의 욕구를 파악하고자 하였다. 이를 위해 곤충 관련 박물관, 체험관, 곤충농장 등을 방문한 적이 있거나 곤충을 구매한 경험이 있는 소비자가 자신의 블로그에 올린 게시물들을 대상으로 자료를 수집하였으며, 게시물의 사진 및 텍스트를 중심으로 내용분석을 실시하였다. 분석결과 애완학습곤충 시장은 자녀의 교육목적을 위한 초등학교 저학년 이하의 자녀를 동반한 가족형 방문형태인 것으로 나타났다. 방문 목적지는 주로 서울, 경기의 수도권에 집중되어있으며, 자녀의 방학기간을 이용한 방문이 가장 많았다. 사진 분석 결과 체험활동에 대한 높은 관심도를 확인할 수 있었으며, 만족한 내용도 체험거리가 많고 다양하다는 것이었기 때문에 앞으로도 직접 체험할 수 있는 다양한 형태의 수준별 체험 프로그램을 개발하여 제공해야 할 것이다. 또한 불만족한 내용은 곤충에 대한 거부감인 것으로 나타나 곤충에 대한 친근한 이미지를 형성할 수 있도록 다른 동물이나 식물과 연계한 프로그램의 개발 등 노력이 필요할 것이다. 또한 애완학습곤충 시장이 계속 성장하고 발전하기 위해서는 곤충종의 다양화 및 곤충을 활용한 체계화된 체험프로그램의 개발이 필요할 것으로 보인다. As the market of educational pet insects is expanding, understanding the consumer needs became more crucial. To achieve the ideal analysis on the market, this research monitored the behavior of consumers. The posting on the blogs of consumers, who have visited insect museums and farms, or have bought insects were collected as data. Moreover, the informational contents, photographs and texts, were analyzed. The results showed that the family-unit visitors with elementary school lower graders were the main type of visitors for their children's education. The visiting areas were concentrated in Seoul and the Metropolitans of Gyeonggi province, and the visits were mostly occurred during their children's vacation period. The analysis of posted photographs showed the visitors' high interest in the hands-on program. According to the texts on visitors' blogs, especially, the largest number of visitors satisfied with the variety of program. It implies the necessity of development in diverse and differentiated hands-on program. Otherwise, the programs available to connect insects to other animals and plants should be introduced to reduce aversion against insects, which was reported as the strongest dissatisfaction. In conclusion, diversification on insect species and development in systematized hands-on program seem to be required for the continuous growth of educational pet insects market.

김소윤,이정복,안형수,김경화,양민,Kim, So Yoon,Lee, Jung Bok,Ahn, Hyung Soo,Kim, Kyung Hwa,Yang, Min 한국결정성장학회 2021 한국결정성장학회지 Vol.31 No.4

ε-Ga₂O₃ 박막은 금속 유기 화학 기상 증착법(MOCVD)에 의해 4H-SiC 기판에 성장되었으며, 결정성은 성장 조건에 따라 평가되었다. ε-Ga₂O₃의 최적 조건은 665℃의 성장 온도와 200 sccm의 산소 유량에서 성장한 것으로 나타났다. hexagonal 핵이 합쳐지면서 2차원으로 성장되었고, hexagonal 핵의 배열 방향은 기판의 결정 방향과 밀접한 관련이 있었다. 그러나 ε-Ga₂O₃의 결정 구조는 hexagonal이 아닌 orthorhombic 구조를 가짐을 확인하였다. 결정상 전이는 열처리에 의해 수행되었다. 그리고 상 전이된 β-Ga₂O₃ 박막과 비교하기 위해 4H-SiC에서 β-Ga₂O₃ 박막을 바로 성장하였다. 상 전이된 β-Ga₂O₃ 박막은 바로 성장한 것보다 더 나은 결정성을 보여주었다. ε-Ga₂O₃ thin films were grown on 4H-SiC substrates by metal organic chemical vapor deposition (MOCVD) and crystalline quality were evaluated depend on growth conditions. It was found that the best conditions of the ε-Ga₂O₃ were grown at a growth temperature of 665℃ and an oxygen flow rate of 200 sccm. Two-dimensional growth was completed after the merge of hexagonal nuclei, and the arrangement direction of hexagonal nuclei was closely related to the crystal direction of the substrate. However, it was confirmed that crystal structure of the ε-Ga₂O₃ had an orthorhombic rather than hexagonal. Crystal phase transformation was performed by thermal treatment. And a β-Ga₂O₃ thin film was grown directly on 4H-SiC for the comparison to the phase transformed β-Ga₂O₃ thin film. The phase transformed β-Ga₂O₃ film showed better crystal quality than directly grown one.

김소윤,윤성희,이윤아,최미경,So-Yun Kim,Seong-Hee Yoon,Yun-A Lee,Mi-Kyeong Choi 대한영양사협회 2023 대한영양사협회 학술지 Vol.29 No.2

This study examined the nutritional information using the nutrition labels of gimbap sold at convenience stores and evaluated nutritional adequacy compared to dietary reference intakes for Korean adolescents. Thirty gimbaps (triangular gimbaps and regular gimbaps according to the main ingredients of vegetables, fish, and meat) were purchased at five convenience stores of different brands with many stores in Korea. The food and nutrition labels of the gimbaps were investigated, and nine minerals were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). The average price of gimbap was 1,906.7 won, and average energy was 292.0 kcal, and the protein content was 15.5% of the recommended intake for Korean male adolescents aged 15~18 years. The mineral content ranged from 6.9% for zinc to 39.0% for selenium. Except for sodium and selenium, the energy, protein, and mineral content did not meet 1/3 of dietary reference intakes for adolescents. For the index of nutritional quality (INQ), calcium and zinc were the lowest in the triangular and regular gimbap, respectively. The INQ of potassium was significantly higher in triangular gimbap with vegetables. The content and INQ of selenium were in regular gimbap with fish, and the zinc INQ was in regular gimbap with meat. Overall, gimbap sold in convenience stores has a high sodium content, and the contents of energy, protein, and minerals, except selenium, are insufficient for a single meal.

Purpose: To evaluate device efficacy using the corneal curvature value. Methods: Prospectively, 35 patients (70 eyes) were enrolled in the present study. Three sets of corneal curvature values were obtained using the autorefractor (RK-F1Ⓡ), manual keratometer (OM-2Ⓡ), partial coherence interferometry keratometer (IOL MasterⓇ), wavefront analyzer (KR-1WⓇ), and videokeratography (Orbscan IIⓇ). Repeatability of each device was evaluated by coefficient of variation, standard deviation, and intraclass correlation coefficient. RM-ANOVA on ranks was used to compare the differences in corneal curvatures among the devices. The Bland-Altman plot was performed to assess measurement agreement among the devices. Results: The coefficient of variation values from each device ranged from 2.92% (IOL masterⓇ) to 3.06% (Orbscan IIⓇ), and the values of intraclass correlation coefficient ranged from 0.965 (KR-1WⓇ) to 0.997 (IOL masterⓇ). Compared with the manual keratometer, there was a maximum corneal curvature difference of 1.23 D in KR-1WⓇ, while the other devices had differences less than 0.82 D. Conclusions: When assessing corneal curvature, the repeatability values were similar among the 5 devices, although a difference greater than 1 D was observed when comparing the KR-1WⓇ to the manual keratometer.

Purpose: To identify the muscle weakening effect and the change of muscle tension according to degree of superior rectus Z-myotomy in rabbits. Methods: After dissection of superior rectus in 15 rabbits (30 eyes), marking was done on 10 mm apart from muscle insertion. Then, Z-myotomy was done on 2 mm and 8 mm apart from muscle insertion which are two different positions on apposite sides. 25%, 50% and 75% Z-myotomy were defined as group 1 (10 eyes), group 2 (10 eyes) and group 3 (10 eyes). After Z-myotomy, the change of muscle lengthening between muscle insertion and marking, and muscle tension were measured. At 4 weeks after Z-myotomy, all parameters were re-measured. Results: After Z-myotomy all markings moved posteriorly, and showed result as 10.83 ± 0.13 mm in group 1, 11.02 ± 0.17 mm in group 2 and 12.01 ± 0.23 mm in group 3 respectively. Muscle tension result showed as 3.98 ± 0.22 mm in group 1, 3.54 ± 0.18 mm in group 2 and 2.87 ± 0.25 mm in group 3. In comparison of three groups, group 2 and group 3 showed the significant results (p < 0.05). At 4 weeks after Z-myotomy the markings showed result as 10.55 ± 0.14 mm, 10.85 ± 0.20 mm, 11.91 ± 0.14 mm respectively, and in group 2 and group 3 the significant changes were seen (p < 0.05). Muscle tensions were 4.01 ± 0.31 mm, 3.88 ± 0.53 mm, 3.12 ± 0.42 mm respectively. There were significant results in group 2 and group 3 (p < 0.05). Conclusions: 75% Z-myotomy of superior rectus showed significant results in muscle weakening and decreasing muscle tension.

동해 울릉분지의 탄산칼슘 포화상태

김소윤,정성희,이동섭,KIM, SO-YUN,JEONG, SEONGHEE,LEE, TONGSUP 한국해양학회 2019 바다 Vol.24 No.3

동해 울릉분지의 탄산칼슘 포화상태를 1999, 2014, 2017, 2018년도 해양 조사를 통해 수집된 pH, 용존무기탄소(DIC), 총알칼리도(TA) 자료를 이용하여 계산하였다. 1999년에 비해 2010년대에 전 수심에서 탄산염 포화상태는 유의하게 감소하였다. 2018년 현재 방해석과 선석의 포화면 수심은 각각 약 500 m와 200 m로 상승하였다. 탄산칼슘 포화상태를 결정하는 주된 화학종인 탄산이온은 상층과 심층에서 다른 분포를 보였다: 상층에서는 약 $175{\mu}mol\;kg^{-1}$로 비교적 높고, 심층에서는 $50{\mu}mol\;kg^{-1}$ 이하로 아주 낮게 나타났다. 그러나 탄산이온 농도의 감소 경향은 심층보다 상층에서 두드러졌는데, 이는 2000년대에 대기에서 이산화탄소의 침투가 주로 상층에서 일어나는 것이 반영된 결과로 해석된다. The calcium carbonate saturation state in the Ulleung Basin of East Sea was calculated using bottle data set of pH, dissolved inorganic carbon and total alkalinity obtained from the year 1999, 2014, 2017, and 2018 cruise. In the 2010s calcium carbonate saturation state was significantly lowered at all depth compared to the 1999 reference state. Accordingly calcite saturation horizon and aragonite saturation horizon shoaled to 500 m and 200 m, respectively. A key chemical species for the calcium carbonate saturation state, carbonate ion showed distinctive profile between upper and deep waters: it is moderately high (${\sim}175{\mu}mol\;kg^{-1}$) in upper waters and very low (< ${\sim}50{\mu}mol\;kg^{-1}$) in the deep waters. However the decreasing trend of carbonate ion concentration was pronounced in the upper water than deep waters, suggesting atmospheric $CO_2$ penetration is largely confined to the upper waters in the 2000s.

Vietnamese cities have a high risk of flooding under climate change due to their geographical characteristics. In this situation, the urban area is expanding with rapid growth of urban population. However, the risk of flooding is increasing due to the increase in impermeable areas and insufficient infrastructure. This study analyzed the urban expansion trend at the national level in Vietnam for the past 10 years (2007-2017) by using the Urban Expansion Intensity Index. Also, this study selected Hue City as a region with a large impact of climate change and a rapid expansion and found the possibility of flooding in the urban expansion area. The result showed that cities have been expanded around major cities in the Red River Delta, Mekong Delta, and coastal areas. In the case of Hue City, the area with fast expansion rate has a higher expected flood area. It implies that the risk of flood disasters may increase if the urabn expansion is carried out without disaster prevention measures. It is expected that Korean urban disaster prevention policies such as urban climate change disaster vulnerability analysis system will be helpful in establishing urban plans considering climate change in the fast growing regions such as Vietnam. 베트남의 도시들은 지리적 특성으로 인해 기후변화에 따른 홍수 위험성이 높은 상황인데, 빠르게 도시지역이 확장됨에 따라 홍수위험성은 더욱 가중되고 있다. 본 연구에서는 도시확장강도지수를 활용하여 지난 10년간(2007년-2017년) 베트남 국가차원에서의 도시확장 추세를 확인한 후, 기후변화 영향이 크고 확장속도가 빠른 지역으로서 후에시를 선정하여 홍수발생가능성을 확인하였다. 그 결과 홍강델타, 메콩델타, 해안지역의 주요 도시 주변으로 확장되었으며, 후에시의 경우 확장속도가 빠른 지역일수록 예상침수면적이 높은 것으로 나타났다. 이는 향후에 홍수재해 위험성이 더욱 커질 수 있음을 의미한다. 재해취약성분석 제도 등 국내의 도시방재정책은 베트남 급성장지역에서 기후변화를 고려한 도시계획 수립 시 도움이 될 것이다.
