임지영 ( Jiyoung Lim ) 한국의류학회 2019 한국의류학회지 Vol.43 No.5

This study established a lower garment sizing system for elderly men over 65 years of age based on 535 males selected from the 5th Korean Anthropometric survey. The results are as follows. Most elderly men body measurements were smaller for adult males (except for the waist area); however, abdominal obesity has changed to body type. The standard deviation was applied around the average values of waist circumference and hip circumference for the suggestion of a lower garment sizing system for elderly men. The interval between the designation was ±2.5 cm with an average waist circumference of 86 cm and ±2 cm with an average hip circumference of 92 cm. A total of 13 designation sections were established in consideration of the cover ratio and cover efficiency. The cover ratio in the 13 nominal sections was 77.2%. The segmental distribution rate presented in the results will also be useful for production planning in specific sizes and enable rational production.

임지영 ( Jiyoung Lim ) 한국의류학회 2020 한국의류학회지 Vol.44 No.2

This study established a lower garment sizing system for abdominal obesity adult women aged 30-59 based on 277 females selected from the 7th Size Korean Anthropometric survey. The criteria for subjects in this study were over 25 kg/m² of the BMI, over 85 cm of waist, and over 0.8 waist hip ratio. The results are as follows. The lower body analysis of abdominal obesity adult women showed that average circumference items were larger than the ordinary size, and the average length items were smaller. The standard deviation was applied around the average values of waist circumference and hip circumference for the suggestion of a lower garment sizing system for abdominal obesity adult women. The interval between the designation was ±1.5 cm with a waist circumference of 100 cm and ±2.5 cm with an average hip circumference of 100 cm. We established 13 designation sections in consideration of the cover ratio and cover efficiency. The cover ratio in the 13 nominal sections was 71.5%. The segmental distribution rate presented in the results will also be useful for production planning in specific sizes that helped enable rational production.

임지영(Lim, Jiyoung),박대석(Park, Dae-Seok),김진한(Kim, Jin-Han) 한국산학기술학회 2015 한국산학기술학회논문지 Vol.16 No.8

단일챔버 미생물연료전지에 분리막으로 세라믹막과 나피온막을 적용하여 전기발생특성을 분석함으로써 세라믹막의적용가능성을 구명하고자 하였다. 또한 환원전극으로서 백금촉매가 도포된 탄소천과 일반 탄소천을 사용하여 백금촉매 효과 및 전기발생특성을 비교하였다. 회분식 실험에서 전기발생특성이 가장 안정적인 것은 acetate를 기질로 사용하였을 때였다. Formate는 전기발생특성이 acetate보다 다소 높았으나 불안정하였고 propionate와 butyrate는 acetate에 비하여 전기발생량이상대적으로 낮았다. 환원전극으로서 백금촉매가 도포되어 있는 탄소천과 일반 탄소천을 비교한 결과 백금촉매가 도포된 탄소천의 전력발생량이 일반 탄소천에 비하여 1.2배 높게 나타났지만 약 5배 정도 비용 차이가 있음을 고려하면 미생물연료전지의 적용에 있어 효율성과 경제성은 함께 고려되어야 할 것으로 판단된다. 분리막으로서 세라믹막과 나피온막을 적용한 미생물 연료전지에서 발생한 평균 전압은 합성폐수를 이용한 실험에서 각각 523.67 mV ± 49.41 mV, 424.09 mV ± 79.95 mV이었다. 미생물연료전지에 분리막으로 세라믹막과 나피온막을 적용하여 전력발생 및 유기물제거효율을 비교한 결과, 세라믹막이 나피온막의 대안이 될 수 있음을 확인하였다. This study attempts to verify the applicability of ceramic membrane as a separator by comparing the power generation characteristics in single-chamber MFCs using ceramic membranes to those in the MFCs using nafion membrane. The generated power in MFCs by using acetate as a substrate was more stable than that by using formate, propionate and butyrate, respectively. It was shown that the generated power by using formate substrate in MFCs was unstable and a little higher than that by using acetate, and the power generated by using propionate and butyrate were lower than that by using acetate. In order to find out the Pt catalyst effect, it was compared the power generated in MFCs using Pt-coated carbon cloth as electrode to that power using normal carbon cloth. The power generated in MFCs using Pt-coated carbon cloth as electrode was 1.2 times higher than that using normal carbon cloth. The Pt-coated carbon cloth was about 5 times more expensive than normal carbon cloth. It is suggested that both power generation efficiency and cost together should be considered in selecting electrodes of MFCs. It was found that the ceramic membrane was superior to nafion membrane by comparing to the power generation characteristics obtained. It was shown that average voltage values were 523.67 mV ± 49.41 mV by using synthetic wastewater, in MFCs of ceramic membrane as a separator. While average voltage values were 424.09 mV ± 79.95 mV by using synthetic wastewater, in MFCs of nafion membrane as a separator. The organic removal efficiency, 41.7% by using ceramic membrane was a little bit higher than 40.8% by using nafion membrane. This research implies ceramic membrane can be a valid alternative to nafion membrane as a separator when considering the power generation and the efficiency of organics removal.

목적 터키인을 위한 한국어교육은 1989년 앙카라대학교에서 한국어문학과가 개설된 이래 본격적으로 시작되었다. 터키인 학습자를 대상으로 한 한국어교육 연구 성과는 지난 30년간 누적되었지만 연구 동향 분석은 아직 한 번도 이루어진 바 없다. 본 연구는 터키인 대상 한국어교육 연구 동향을 분석하여 지금까지의 연구 성과를 확인하고 앞으로의 연구 방향들을 탐색하고 논의하는 데 그 목적이 있다. 방법 연구 자료는 터키인 학습자 대상으로 연구된, 국내에서 출판된 학위논문과 학술논문, 총 58편으로 한정한다. 연구 방법은 분류 기준에 의한 질적 분석과 네트워크 언어분석을 통한 양적 분석으로 이루어진다. 결과 주제 분류 분석 결과, ‘교수 학습 57%>한국어 교육내용 34%>한국어 교육 일반 9%’ 순으로 연구가 많이 진행되었으며, 하위 주제는 ‘문법 22%>교재 16%>한국학 교수 14%>습득 및 학습(오류분석) 10%, 어휘 10%’ 순으로 많이 이루어졌다. 즉 문법, 어휘 등과 같은 기초 교육 내용 마련을 위한 연구, 실제 교수에 시급히 필요한 교재 연구가 주를 이루었으며, 한국학 연구의 비중이 큰 것이 특징적이다. 또한 네트워크 언어분석 결과, ‘대조, 오류, 교재, 문학’이 중심어로 드러났는데, 이는 앞선 주제 분류 분석 결과와 일치하며 연구 전반에 걸쳐 사용된 분석 방법인 ‘대조 분석’까지 도출되었다. 결론 이후 분석 결과에 근거해 한국어 교육 내용 및 교수⋅학습 면에서 향후 보완되어야 할 연구 방향을 제안하였다. Objectives Korean language education for Turks started in earnest in 1989 when the Korean Literature Department was opened at Ankara University. Research results in Korean language teaching on Turkish learners have accumulated over the past 30 years, but no analysis of research trends has yet been carried out. The aim of this study is to analyze research trends in Korean language education for Turks in order to confirm the attainments and discuss future directions of the research. Methods Research material is limited to 58 academic papers and articles published in Korea, which have been studied for Turkish learners. The research method consists of qualitative analysis based on classification criteria and quantitative analysis using network language analysis. Results “Teaching-Learning 57%,” “Korean Education Content 34%,” and “Korean Education General 9%.” The most studied sub-topics are ‘22% Grammar> 16% Textbook> 14% Korean Studies Professor> 10% Acquisition and Learning (error analysis) and 10% Vocabulary’. In other words, research aimed at the preparation of basic educational contents such as grammar and vocabulary, and the research on textbooks which is urgently needed for teaching proper was primarily centered on Korean studies. In addition, network language analysis revealed that “contrast, error, textbook, literature” were the central words. This was consistent with previous subject classification analysis results. And the analysis method used throughout the studies, ‘contrast analysis’, was derived. Conclusions Following the analysis of the topic clssification, numerous studies were conducted in the order of Based on the results of the analysis, we proposed Korean educational content and the direction of the research that should be complemented in the future in terms of teaching and learning.

본 연구는 lab-scale로 제작된 가압식 마이크로버블 발생장치의 버블크기 분포를 분석하여 장치의 최적 운전조건을 검토하고 벤튜리 노즐 제원에 따른 마이크로버블 발생 특성을 확인하였다. 실험결과, 실험실 규모의 가압식 마이크로버블 발생장치의 운전조건은 공기 주입율 0.3 LPM, 가압탱크압력 3 bar, 벤튜리 노즐을 수조와 직접 연결 하였을 때, 상대적으로 우수한 성능을 나타내었다. 벤튜리 노즐 제원을 달리한 마이크로버블 발생 특성에서는 노즐의 제원에 따른 버블크기 분포에 미치는 영향은 낮지만, 버블 발생의 성능적 측면에서는 노즐의 목 직경이 3-4 mm 일 때, D50이 54.98– 61.19 ㎛(D3L15, D4L15), 50 ㎛이하의 버블 분율은 각각 0.326, 0.345(D3L15, D4L15)로 상대적으로 우수함을 확인하였으며, 노즐 목 길이의 경우 목 길이가 20 mm인 노즐의 D50이 49.40–54.98㎛, 50 ㎛이하의 버블 분율은 0.447로서, 마이크로버블을 비교적 안정적 으로 발생시키는 것을 확인 할 수 있었다. This research was performed to review operating parameters, optimum condition and check characteristic of microbubble generation for using bubble size distribution according to venturi specification. Optimum operating condition have airflow rate 0.3 LPM, 3 bar(pressure tank) and connecting nozzle directly(without valve), it is advantageous to generate microbubble. In case of characteristic of microbubble generation according to venturi specification, effect that nozzle specification affects bubble size distribution is low impact. But considering performance aspects, when using nozzle that throat diameter 3-4 mm, D50 are 54.98– 61.19 ㎛(D3L15, D4L15), fraction of bubble less than 50 ㎛ are 0.326, 0.345. And it is superior to others. Besides, D50 and fraction of bubble less than 50 ㎛ of throat length 20 mm are 49.40–54.98 ㎛, 0.447, respectively And nozzle that throat length 20 mm is relatively tendency to generate microbubble stably.

Objective: The purpose of this study was to quantitatively evaluate the Wii Balance Board (WBB)-based jump performance forthe elderly and to confirm the difference in jump performance according to age. Design: Cross-sectional study. Methods: 40 young adults (aged 22.5±2.2 years) and 33 elderly (aged 75.1±5.2 years) without orthopedics disease participated inthis study. Standing on the WBB then, with the signal “start,” jump vertically to the maximum height at which you can jump, land on the force plate after jump and keep it standing on both feet. All subjects were required to practice the jump sufficiently beforestarting the measurement, each measuring three times, and the mean values were used. A one-minute break was provided betweeneach trial. Evaluators waited within 1meter for every test to prepare for fall. Results: The vertical ground reaction force of elderly and young adults when jumping using WBB showed a significant difference(p<0.05) and demonstrated discriminant validity. Between two groups, there were significant differences in overall jump time (p<0.05), maximum value (p<0.05), minimum value (p<0.05), center of pressure (COP) pathlength (p<0.05), and flight time p<0.05). Conclusions: This study found that performing the vertical jump, the elderly showed longer jump time, lower vertical groundreaction force, COP pathlength and shorter flight phase than healthy young adults using WBB and demonstrated that as a measurement tool, WBB discriminated vertical jump performance between elderly and young adults.
