The various oriental herbal medicines, which have usually been used for treatment of reducing fever, purging intense heat and detoxication, were screened to determine the antibacterial activity and the minimal inhibitory concentration against antibiotics-resistant Staphylococcus aureus. The results obtained were as follows: 1. Among the 23 oriental medicines tested, the water-soluble extract of Coptis japonica showed very excellent antibacterial activity against antibiotics-sensitive and -resistant S. aureus. A little activity was found in the extracts of Scutellaria baicalensis, Eriobotrya japonica and Prunus mume against antibiotics-sensitive S. aureus and in that extracts of P. mume, Schizandra chinensis and S. baicalensis against antibiotics-resistant S. aureus. When C japonica was used, the high antibacterial activity was shown against Bacillus subtilis and other extracts showed a little or no antibacterial activity against B. subtilis and E. coli as a control. 2. The highest antibacterial activities against antibiotics-resistant S. aureus were found in the ethanol-soluble extract of C japonica. Other ethanol-soluble extracts of S, baicalensis, S. chinensis and P. mume showed a little activity against both antibiotics-sensitive and antibiotics-resistant S. aureus. 3. Among the medicinal herbs tested, the water- and ethanol extracts of C. japonica showed very excellent antibacterial activity against the pathogenic S. aureus and both Escherichia coli and Bacillus subtilis used as a control. 4. When the water-soluble extracts of C. japonica and S. baicalensis, minimal inhibitory concentrations (MICs) against antibiotics-sensitive S. aureus were $20mg/m{\ell}\;and\;30mg/m{\ell}$, respectively. The MICs of the ethanol-soluble extracts of C. japonica and P. scabriosaefolia were $7.5mg/m{\ell}\;and\;12mg/m{\ell}$, respectively. 5. For the MICs against antibiotics-resistant S. aureus, the water-soluble extracts of C. japonica and P. mume showed $15mg/m{\ell}\;and\;10mg/m{\ell}$, respectively. The MICs of the ethanol-soluble extracts of C. japonica and P. mume were $13mg/m{\ell}\;and\;20mg/m{\ell}$, respectively. As a result, the highest antibacterial activity was found in both water- and ethanol-soluble extracts of C. japonica against antibiotics-resistant S. aureus. And the water- and ethanol-soluble extracts of S. baicalensis, S. chinensis and P. mume showed comparatively high antibacterial activities against both antibiotics-sensitive and -resistant S. aureus.

공공 건설사업의 계약에 있어 합리적이며 적정한 예정가격의 산정이 가장 중요한 요소라 할 수 있다. 공공 공사 예정가격 산정 근거로 사용되어 온 표준품셈과 더불어 실적공사비 제도를 단계적으로 확대 도입키로 했다. 본 논문에서는 과거에 낙찰되었던 계약단가 뿐 아니라 모든 입찰단가 자료를 활용하여 산출한 실적단가의 변동패턴을 분석하여 예측하는 일련의 절차 및 방법론을 제시하였다. 본 연구에서는 신뢰성 있는 자료 확보를 위해 저가입찰 등과 같은 전략적 입찰단가를 제거한 실적단가를 활용하여 시계열 자료를 구성하여 이 시계열을 웨이블릿 분석을 통해 변동 패턴과 추세를 파악하고 신경망을 이용하여 공사비를 예측하는 방안을 주요하게 다루고 있다. 건설 공사비는 매우 다양한 특성을 내포하고 있으므로 그 예측이 어려울 뿐만 아니라 그 오차 또한 매우 클 것으로 예상된다. 이에 본 연구에서는 웨이블릿 변환을 통하여 다양한 특성의 변동을 찾아내어 이를 예측에 이용함으로써 예측력을 높이고자 하였다. 다만 시계열이 매우 단기간의 자료로 구축되어 변동의 양상이 정확하게 분석될 수 없었으나 지속적으로 실적공사비 자료기 축적되어 장기간의 자료를 바탕으로 시계열이 구축된다면 향후 수행될 건설사업의 기획 시 개략적인 공사비 산출에 참고할수 있는 유용한 자료로 활용될수 있을 것이다. The Korea Standard of Estimate which has been used as the only basis of Cost estimate of public construction projects is failed to reflect the fluctuation of current construction cost. Therefore, the government decided to gradually introduce historical construction cost into cost estimate of public construction projects from 2004 and to reduce the use of Korean Standard of Estimate. This paper presents a series of process and the methodology for computing Actual Cost and analyzing the fluctuation patterns based on not only previous contract prices which made a successful bid but also all of the other bid prices. Also, this paper mainly handles a device for extracting strategic bid price such as low price bid for assuring reliable data and for predicting the construction cost which is built by Wavelet Analysis of Time series Analysis data and Neural Network. It is anticipated that the effective use of the proposed process for estimating actual unit cost would make the cost estimation more current and reasonable.

In this paper, a monopole antenna applicable to WLAN/WiMAX system is designed and fabricated. The proposed antenna is designed to have three lines and one slit based on microstrip feeding to have triple band characteristics. We optimized the lengths and slits of the three lines to obtain the required characteristics for this paper. The proposed antenna has $32.0mm(W2+W3){\times}47.1mm$ (L3+L4+L5+L8) on a dielectric substrate of $42.5mm(W1){\times}52mm(L1){\times}1.0mm$ size. From the fabrication and measurement results, bandwidths of 158 MHz (813 to 971MHz), 630 MHz (2.10 to 2.73GHz) and 1190 MHz (4.83 to 6.02GHz) were obtained based on the impedance bandwidth. The fabricated antenna also obtained the measured gain and radiation pattern in the required triple band. 본 논문에서는 W-LAN/WiMAX 시스템에 적용 가능한 모노폴 안테나를 설계 제작하였다. 제안된 안테나는 마이크로스트립 급전을 바탕으로 세 개의 선로와 하나의 슬릿을 갖도록 구성하여 삼중대역 특성을 갖도록 설계하였다. 세 개의 선로의 길이와 슬릿을 적절하게 조정하여 본 논문에서 요구되는 특성을 얻기 위한 최적화된 수치를 얻었다. 제안된 안테나는 $42.5mm(W1){\times}52mm(L1){\times}1.0mm(t)$의 유전체 기판 위에 $32.0mm(W2+W3){\times}47.1mm$ (L3+L4+L5+L8)의 크기로 제작되었다. 제작 및 측정 결과로부터 158 MHz (813 ~ 971MHz), 630 MHz (2.10 ~ 2.73GHz) 그리고 1190 MHz (4.83 ~ 6.02GHz)의 대역폭을 얻었다. 또한 제작된 안테나의 통해 삼중대역 안테나에서 요구되는 이득과 방사 패턴 특성을 확인하였다.

The basic type construction cost which is the base of the building cost estimation is being adjusted according to the price changes by utilizing the apartment construction cost index in order to flexibly operate it. In this study, we analyzed the change trends and characteristics of the housing cost index for the basic type building cost model project operated from September, 2012 to March, 2018. As a result, the increase in material costs is slight while the share of the labor cost increased in the construction cost due to the rise of labor unit price, leading to a perceived increase in sensitivity of labor costs. We should be careful to keep the sensitivity of the material cost and the labor cost to an appropriate level so that the index may not be distorted.

PURPOSE: This study was conducted to investigate the effects of vibration frequency and amplitude on scapular winging during the knee push-up plus exercise. METHODS: A total of 26 female subjects with scapular winging were evaluated while performing the knee push-up plus exercise with no vibration, low-frequency/low-amplitude (5 Hz/3 mm) vibration, low-frequency/high-amplitude (5 Hz/9 mm) vibration, high-frequency/low-amplitude (15 Hz/3 mm) vibration, and high-frequency/high-amplitude (15 Hz/9 mm) vibration. The surface EMG of the serratus anterior (SA) muscle was compared between the vibration frequency and amplitude. The EMG amplitude was normalized using the maximal voluntary isometric contraction (MVIC). The statistical significance of the results was evaluated using one-way ANOVA. RESULTS: The SA muscle EMG values increased at low-frequency/low-amplitude vibration and at low-frequency/high-amplitude vibration compared to no vibration. Furthermore, the same values increased at high-frequency/low-amplitude vibration and high-frequency/high-amplitude vibration compared to no vibration. In general, a higher vibration frequency and amplitude was associated with higher EMG values of the SA muscle, with particularly greater increases observed during high-frequency/high-amplitude vibration. There was also a significant difference between each condition with a high-frequency/high-amplitude vibration (p<.05). CONCLUSION: This study suggests that there were remarkable clinical effect of the knee push-up plus exercise with vibration, which enhanced the SA muscle activation in persons with scapular winging. Furthermore, applying a higher vibration frequency and amplitude more effectively increased for increasing SA muscle activation.

박원영(Park, Won-Young),이선미(Lee, Sun-Mi) 한국영유아보육학회 2021 한국영유아보육학 Vol.- No.126

본 연구는 어린이집에서 영유아와 함께 놀이하는 보육교사들의 경험을 탐색하기 위해 현상학적 질적 연구방법으로 실시되었다. 서울 지역 소재의 사단법인 A어린이집에서 근무하는 보육교사 8명을 대상으로 6개월 간 심층적 개별면담을 실시하였다. 연구결과는 첫째, 보육교사가 경험한 놀이는 보편적으로 부정적이었다. 둘째, 실외 놀이에서 보육교사의 자율성이 증가하였다. 보육교사가 영유아의 놀이에 집중하면서 놀이시간과 유형이 확대되었고, 자연스럽게 보육교사의 자율성이 확장되는 경험으로 연계되었다. 이와 같은 과정을 통해 보육교사는 영유아가 원하는 놀이를 발견하고, 운영하면서 보육 전문가로서의 놀이 경험의 폭과 질을 함양시키는 것으로 파악할 수 있었다. 향후 영유아와 보육교사가 함께 계획 · 실행하고 평가하는 놀이 교육과정 즉, 서로의 의견이 존중된 놀이를 확장함으로써 영유아와 보육교사 모두가 개인적 성장과 발달에 기여하는 경험을 공유할 수 있을 것으로 기대된다. The purpose of this study is to look into the experiences of child care teachers who play with young children at a daycare center, using a phenomenological qualitative research method. The study was conducted by carrying out individual in-depth interviews for six months with eight child care teachers working at daycare center ‘A’ located in Seoul. The study came up with two outcomes. First, the child care teachers generally experienced negative play. Second, the level of autonomy of the teachers increased during outdoor play. When the child care teachers paid more attention to the play of young children, the playtime, the types of play, as well as the level of autonomy of the teachers increased accordingly. It was observed that through this process, the child care teachers were able to develop themselves as child care professionals with in-depth and quality playing experiences by discovering and running the play that young children actually liked. In this regard, it can be expected that both young children and child care teachers can share the benefits of personal growth and development by planning, implementing and assessing the play curriculum together, or in other words, by having more play time that reflect the opinions of both sides.
