나영주 한국의류산업학회 1999 한국의류산업학회지 Vol.1 No.4

Twenty-three fabrics of varying thicknesses and weights were subjected to the maximum pressures of 10, 20, 35, 50 and 70 gf/㎠ to yield pressure-thickness curves. Compression properly values were plotted according to the amount of pressure applied to the samples. Pressure increases resulted in decreases in LC (compressional curve linearity), increases in WC (compressional energy) and no change in RC (compressional resilience). The best-fit lines are found separately according to pressures. The thickest fabrics exhibited the highest LC and WC values. The slopes varied different according to the pressure applied, with a pressure 50 gf/㎠ exhibiting the steepest slope at WC. The pressure of 20 gf/㎠ correlated most closely with the hand-evaluation test results, yielding Spearmans correlation coefficients of .86 and .82 respectively for the LC and WC.

겨울철 온맵시 착용과 과거 유행인 엠파이어스타일 로우브의 보온성

나영주,오산,김지수 한국감성과학회 2015 춘계학술대회 Vol.2015 No.-

온맵시란 겨울을 따뜻하게 보낸다의 의미의 온 온과 옷을 차려입은 모양새, 스타일을 의미하는 순 우리말 맵시가 합쳐진 말로 내복이나 보조용품, 여러 기능성 의복을 착용하자는 뜻이 포함한다. 현재 대기오염, 환경파괴, 에너지 낭비 등이 지나치고 나날로 겨울철 쾌적온도가 상승하고 있다. 우리 생활에서 가장 밀접한 관계가 있는 에너지부분은 냉난방이며 이를 조금 줄이는 것만으로도 엄청난 온실가스 저감효과를 볼 수 있다. 그러나 복식사상 하나의 패션으로서 크게 자리 잡은 엠파이어 스타일 로우브의 열저항성에 대한 궁금증을 해소하고자 하였다. 그 당시 엠파이어 스타일 로우브 착용을 통한 자연과 자유, 평등에 대한 이 무모한 갈망은 인체에 해가 되는 환경 조건을 형성하였다. 이러한 대표적인 엠파이어 스타일 패션을 찾아서 고증, 제작한 후 인체 착용의 폐단에 대하여 연구하고자 하였다. 이를 위하여 많은 문헌과 당시의 관련 데이터들의 직접적인 수집과 연구를 통해 연구배경에 대해 이해를 도모하였다. 고증복의 보온성 측정 실험 연구를 위하여 엠파이어 스타일, 즉 쉬미이즈 드레스 robe(죠세핀이 입었던 얇은 속옷 같은 스타일)를 각종 문헌과 자료를 참고하여 고증하고 실물로 제작하여 준비하였다. 이를 위해서는 정밀한 고증과 타당하고도 합리적인 연구방법의 계획이 필수적이므로 이를 발견하기 위한 다양한 방법을 고찰, 시도하는 효과를 갖는다. 각종의복의 열 저항에 대한 데이터베이스가 정립된 반면에 역사적인 의복의 열 저항에 관한 데이터는 부족한 형편이므로, 역사적인 고증, 기후에 따른 적정 의복 착용 등과 관련하여 문헌자료를 참고, 고증하여 엠파이어 스타일 3벌을 제작(가슴둘레 66 사이즈, 드레스폭 250cm, 길이 159cm) 하였으며, 이 의복에 대하여 의복의 보온성을 측정하였는데 의복의 보온성을 thermal manikin(Sweating thermal manikin, MTNW 미국, Newton사, 신호수집 및 모니터링용 PC, 전극/센서 및 cable) 을 이용하여 객관적인 의복의 보온성을 측정하였다. 보온성 시험규격은 ISO 15831이었다.

The purpose of this study is to investigate changes in the handle of wool/nylon blend fabrics bleached by a protease treatment and to compare their dyeing behavior and handle with those bleached by hydrogen peroxide treatment. Stiffness of wool fabric increased with treatment time in the case of $H_2O_2$ bleaching, while it decreased in the case of protease treatment in the order of Savinase, Alcalase, and Alcalase/$H_2O_2$. Smoothness and fullness showed no differences between the bleaching methods, and they increased with treatment time until 40 min and decreased thereafter. The increase in smoothness was smallest in $H_2O_2$ treatment. Total hand value increased until 40 min regardless of the bleaching method and decreased after 60 min treatment, with the protease-bleached fabric decreasing drastically. The rate of dye absorption for the protease-treated fabric was faster than that for the $H_2O$$_2$-treated fabric, whereas time taken for equilibrium to be attained was almost same. K/S value was high in the order of untreated, $H_2O_2$ , Alcalase/$H_2O_2$, and Alcalase and the color of protease-bleached fabric was brighter than that of $H_2O_2$ bleached one.

나영주,김선국 대한건축학회지회연합회 2017 대한건축학회연합논문집 Vol.19 No.4

PC부재를 현장생산 하는 경우 운송비와 공장의 O&P 절감으로 인해 공장생산 대비 20% 내외의 원가를 절감 될 수 있는 것은 기존의 연구로 확인되었다. 그러나 아직 제한된 공간에서 현장 생산하는 것은 매우 어려운 것으로 인식되고 있다. 이러한 부정적 인식은 공기, 원가 및 생산성을 개선할 기회를 상실할 수 있다. 이러한 문제를 해결하기 위하여 주어진 조건 하에서 PC부재의 현장생산을 체계적으로 수행하는 프로세스 연구가 필요하다. 따라서 본 연구의 목적은 프리캐스트 콘크리트 부재의 효율적 생산을 위한 프로세스를 제안하는 것이다. 본 연구를 위해 사례현장을 선정하여 PC부재 현장생산 계획을 수립하였다. 수립된 계획에 따라 현장생산을 수행하고, 그 결과를 분석하였다. 분석된 내용을 바탕으로 세부작업(detail activities)별 개선사항과 효율적 현장생산 프로세스를 제안하였다. 본 연구의 결과는 생산성 향상을 위한 work process 개선 연구에 학문적으로 기여하고, 실무적으로 현장생산 계획의 체계적 수립을 지원한다. It has been confirmed by previous studies that costs can be reduced by about 20% compared to factory production due to overhead and profit savings of plants with transportation costs when the PC member is produced in site. However, in-situ production in a limited space is perceived as very difficult. These negative perceptions can lead to loss of opportunities to improve time and cost issues with productivity. To solve these problems, it is necessary to study the process of systematically carrying out in-situ production of PC members under given conditions. Therefore, the purpose of this study is to propose a process for the efficient in-situ production of precast concrete members. For this study, the case site was selected and the production plan of the PC member site was established. In-situ production was carried out according to the established plans and the results were analyzed. Based on the analyzed results, the authors propose improvements for detail activities and efficient in-situ production process. The results of this study contribute academically to the improvement of the work process to improve the productivity and support the systematic establishment of the in-situ production plan in practice.

국내외 교육시설물 내진보강공법에 대한 가이드라인 비교 분석 연구

나영주,하선근,손승현,손기영,이주형 한국건축시공학회 2019 한국건축시공학회지 Vol.19 No.2

The domestic earthquake-resistant regulation was legislated firstly in 1988. However, The magnitude and frequencyof earthquakes has been risen in South Korea. Therefore, the mandatory target of earthquake-resistant has beenexpanded. The earthquake-resistant rates of public facilities have been increased by 58.3%. On the other hand,education facilities are low with 24.8%. For the reason, more than 50% of the educational facilities are expected to bedamaged by the earthquake. Especially, the 45% of educational facilities were damaged at Po-Hang earthquake. As aresult, the importance of the seismic retrofit for applying existing education facilities was ended up attracting people’sinteresting. In this respect, in order to develop a effective seismic retrofit method, many researchers have beenconducted researches and it is expected to be actively carried out in the future. However, it is insufficient to considerthat how far technology has been developed. Therefore, the purpose of this study is a comparative analysis ofprecedent guidelines in regard to seismic retrofit applying existing education facilities between domestic and othercountries. Finally, the directions of future research are suggested. 국내 내진규정은 1988년에 최초로 제정되었으나 국내에서 발생하는 지진의 규모와 발생빈도가 증가하면서 내진 의무대상을 지속적으로 확대시켜왔다. 공공 시설물의 내진율은 58.3%로 증가한 반면에 교육 시설물의 내진율은 24.8%에 그치고 있는 실정이다. 이로 인해, 지진발생 시 국내 교육시설물의 50% 이상이 대규모피해를 받을 것이라 예측되고 있다. 실제로 포항지진에 의해 발생한 피해는 45%가 교육시설물로 나타남에 따라 국내 기존 교육시설물에 대한 내진 보강은 국민들의 주요 관심사가 되었다. 보다 효과적인내진 공법을 개발하기 위하여 국내의 많은 연구자들이 연구를 수행해왔으며 앞으로도 활발히 진행될 것으로 예상된다. 하지만, 국내 기술의 발전이 어느 정도까지 이루어졌는가에대한 고찰은 부족한 실정이다. 이에 본 연구에서는 국내·외 기존 교육시설물의 내진에 대한 가이드라인을 비교·분석하고 향후 연구 방향을 제언하고자 한다.
