This study was accomplished to investigate the prevalence of obesity among the 229 elementary school children(boys; 115 persons, girls; 114 persons) during 4 years by retrospective study. The results were as follows; 1. The mean height and weight of 229 subjects were 143.2cm(boys; 143.4cm, girls; 142.7cm), 38.8kg(boys; 40.4kg, girls; 36.9kg), respectively. And other anthropometric body index such as the mean BMI, Rohrer Index, WLI and Obesity Index of subjects were 18.8(boys; 19.5, girls; 18.0), 1.31(boys; 1.36, girls; 1.26), 115.5(boys; 121.4, girls; 108.9) and 110.6(boys; 114.5, girls; 106.7), respectively. 2. The mean percentile values of height and weight of subjects were higher than the '85 Korean Children's Growth Standard, respectively. In the case of boys, the 75th percentile value of weights was larger than that's 97th's. And in the case of girls, the 75th percentile value of weights was equalled to the that's 90th's. 3. When the subjects were classified into 4 groups such as obese, overweight, normal, and lean groups according to Obesity Index, their percentages were 28.8%(boys; 38.3%, girls; 19.3%), 11.8%(boys; 9.6%, girls; 14.0%), 50.7%(boys; 47.0%, girls; 54.4%) and 8.7%(boys; 5.2%, girls; 12.3%), respectively. And only 1 person(3.3%) is classified into normal group and 2 persons(6.7%) are classified into overweight group when they become 5 grade among 30 persons(13.1%) who were classified into obese group when they were 1 grade. 4. Changes in percentage of subjects differentiated by 3 indices during 4 years(from 1 grade to 5 grade) were as follows; In the case of BMI were 5.2%, 5.2%, 11.8%, 21.0%, 27.5%. In the case of Ro¨hrer Index were 13.1%, 11.8%, 14.4%, 14.8%, 17.8%. And in the case of WLI were 15.7%, 21.6%, 29.5%, 32.2%, 36.7%. 5. There was no significant difference among 4 groups on the skip rate of breakfast(obese; 48.5%, overweight; 55.6%, normal; 55.2%, and lean; 65%). The mean meal time of subjects took about 10 minutes which was short, and the eating rate of obese group was significantly shorter than that of other groups(p<0.05). There was a tendency that the rate of the obese or overweight group eating together in breakfast and dinner was lower than that of normal or lean group. The mean T.V. watching time and the rate of eating out of subjects were 1-2 hours/day and 1 or 2 times/week. In conclusion, the subjects have been grown remarkably compared to the '85 Korean Children's Growth Standard, especially boy's weight. In order to the elementary school children to be grew as healthful citizen they should recognize the importance of meals of everyday, the balanced meals, and desirable eating habits. In addition to these, we should educate the ways of meal-life to them. We also are in need to develope the methods of education for the students themselves and their parents so that could prevent the increase rate of obesity.

지난 수십년간 인류에게 핵심적인 에너지 자원이었던 화석연료가 갈수록 고갈되고 있고, 산업발전에 따른 오염이 심해지고 있는 환경을 보호하기 위한 노력의 일환으로, 친환경 이차전지, 수소발생 에너지 장치, 에너지 저장 시스템 등과 관련한 새로운 에너지 기술들이 개발되고 있다. 그 중에서도 리튬이온 배터리 (Lithium ion battery, LIB)는 높은 에너지 밀도와 긴 수명으로 인해, 대용량 배터리로 응용하기에 적합하고 산업적 응용이 가능한 차세대 에너지 장치로 여겨진다. 하지만, 친환경 전기 자동차, 드론 등 증가하는 배터리 시장을 고려할 때, 수명이 다한 이유로 어느 순간부터 많은 양의 배터리 폐기물이 쏟아져 나올 것으로 예상된다. 이를 대비하기 위해, 폐전지에서 리튬 및 각종 유가금속을 회수하는 공정개발이 요구되는 동시에, 이를 재활용할 수 있는 방안이 사회적으로 요구된다. 본 연구에서는, 폐전지의 재활용 전략소재 중 하나인, 리튬이온 배터리의 대표적 양극 소재 Li2CO3의 나노스케일 패턴 제조 방법을 소개하고자 한다. 우선, Li2CO3 분말을 진공 내 가압하여 성형하고, 고온 소결을 통하여 매우 순수한 Li2CO3 박막 증착용 3인치 스퍼터 타겟을 성공적으로 제작하였다. 해당 타겟을 스퍼터 장비에 장착하여, 나노 패턴전사 프린팅 공정을 이용하여 250 nm 선 폭을 갖는, 매우 잘 정렬된 Li2CO3 라인 패턴을 SiO2/Si 기판 위에 성공적으로 형성할 수 있었다. 뿐만 아니라, 패턴전사 프린팅 공정을 기반으로, 금속, 유리, 유연 고분자 기판, 그리고 굴곡진 고글의 표면에까지 Li2CO3 라인 패턴을 성공적으로 형성하였다. 해당 결과물은 향후, 배터리 소자에 사용되는 다양한 기능성 소재의 박막화에 응용될 것으로 기대되고, 특히 다양한 기판 위에서의 리튬이온 배터리 소자의 성능 향상에 도움이 될 것으로 기대된다. For the past few decades, as part of efforts to protect the environment where fossil fuels, which have been a key energy resource for mankind, are becoming increasingly depleted and pollution due to industrial development, ecofriendly secondary batteries, hydrogen generating energy devices, energy storage systems, and many other new energy technologies are being developed. Among them, the lithium-ion battery (LIB) is considered to be a next-generation energy device suitable for application as a large-capacity battery and capable of industrial application due to its high energy density and long lifespan. However, considering the growing battery market such as eco-friendly electric vehicles and drones, it is expected that a large amount of battery waste will spill out from some point due to the end of life. In order to prepare for this situation, development of a process for recovering lithium and various valuable metals from waste batteries is required, and at the same time, a plan to recycle them is socially required. In this study, we introduce a nanoscale pattern transfer printing (NTP) process of Li2CO3, a representative anode material for lithium ion batteries, one of the strategic materials for recycling waste batteries. First, Li2CO3 powder was formed by pressing in a vacuum, and a 3-inch sputter target for very pure Li2CO3 thin film deposition was successfully produced through high-temperature sintering. The target was mounted on a sputtering device, and a well-ordered Li2CO3 line pattern with a width of 250 nm was successfully obtained on the Si substrate using the NTP process. In addition, based on the nTP method, the periodic Li2CO3 line patterns were formed on the surfaces of metal, glass, flexible polymer substrates, and even curved goggles. These results are expected to be applied to the thin films of various functional materials used in battery devices in the future, and is also expected to be particularly helpful in improving the performance of lithium-ion battery devices on various substrates.

For the past several decades, various next-generation patterning methods have been developed to obtain welldesigned nano-to-micro structures, such as imprint lithography, nanotransfer printing (nTP), directed self-assembly (DSA), Ebeam lithography, and so on. Especially, nTP process has much attention due to its low processing cost, short processing time, and good compatibility with other patterning techniques in achieving the formation of high-resolution functional patterns. To transfer functional patterns onto desirable substrates, the use of soft materials is required for precise replication of master mold. Here, we introduce a simple and practical nTP method to create highly ordered structures using various polymeric replica materials. We found that polymethyl methacrylate (PMMA), polystyrene (PS), and polyvinylpyridine (PVP) are possible candidates for replica materials for reliable duplication of Si master mold based on systematic analysis of pattern visualization. Furthermore, we successfully obtained well-defined metal and oxide nanostructures with functionality on target substrates by using replica patterns, through deposition and transfer process. We expect that the several candidates of replica materials can be exploited for effective nanofabrication of complex electronic devices.

서은덕,강영림 慶南大學校 附設 工業技術硏究所 1997 硏究論文集 Vol.15 No.1

n-부틸알코올-플라즈마중합박막을 폴리에스테르 표면위에 생성시켜 표면의 특성을 개질 하였다. 폴리에스테르의 표면은 생성된 박막 내의 친수성기에 의해 친수성으로 개질되었으며 친수성의 정도는 박막내의 산소함량과 밀접한 관계가 있었다. 한편 박막은 발수 및 방오의 효과를 갖는 보호성 차단막으로서의 특성도 나타내었다. We have modified surface property of polyster by deposition of the n-butyl alcohol plasma polymerized thin film. The surface property of polyester was modified to hydrophilic and the hydrophylicity depended closely on the oxygen content of the thin films. The thin film has also protactive barrier property, water repellency, and stain proof property.
