루이보스티에서 5종의 phenolic acid (gallic acid, chlorogenic acid, caffeic acid, p-coumaric acid, trans-ferulic acid)와 9종의 flavonoid (procyanidin b1, aspalathin, rutin, vitexin, hyperoside, isoquercitrin, luteolin, quercetin, chrysoeriol)를 UPLC-MSMS를 이용하여 동시 분석하였다. 14종 페놀릭류를 동시 분석하기 위하여 기기조건과 유효성을 검증하였고 확립된 분석방법을 이용하여 시중에 유통중인 루이보스티 30건을 채취하여 페놀릭류를 분석하였다. 루이보스티 1 g 혹은 1티백에 뜨거운 물 100 mL을 가하여 3분, 6분, 30분이 경과 후 그리고 차가운 물 ($25-30^{\circ}C$)에 30분 우려낸 루이보스티의 페놀릭류 함량을 구하였다. 루이보스티에서 전체 실험대상 페놀릭류 중 rutin과 aspalathin이 가장 많이 추출되어 나왔으며 각각 물질의 함량은 제품별로 달랐다. 페놀릭류 성분의 추출효율은 14종 페놀릭류의 총합 기준으로 뜨거운 물 30분 > 6분 > 3분 > 차가운 물 30분 순으로 높았다. A simultaneous determination of 5 phenolic acids (gallic acid, chlorogenic acid, caffeic acid, pcoumaric acid, trans ferulic acid) and 9 flavonoids (procyanidin b1, aspalathin, rutin, vitexin, hyperoside, isoquercitrin, luteolin, quercetin, chrysoeriol) in rooibos tea has been carried out by ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS). A validated analysis method in this study was applied to rooibos aqueous infusions. Rooibos tea is an antioxidant-rich tea which has anti-cancer, anti-aging, anti-inflammatory, anti-diabetic effect. Extraction yield of phenolics depends on steeping time and temperature of water. Tea infusions were prepared by placing 1 g of tea leaves or 1 tea bag in 100 mL of boiled water, and then at 3, 6 and 30 minutes intervals the infused teas were taken to carry out the analysis of phenolic contents. Another tea infusion was conducted with cold water ($25-30^{\circ}C$) for 30 minuntes. As a result, the total amount of phenolics was highest in rooibos tea steeped with hot water for 30 minutes, followed by 6 minutes, 3 minutes and cold water 30minutes and the result has statistical significance.

본 연구는 ‘돌봄’과 ‘배움’의 관점에서 지역아동센터에서의 아동의 일상을 기술하고 이를 기반으로 지역아동센터의 교육적 역할과 한계를 살펴보는 것을 목적으로 한다. 이를 위해 광주지역 두 개의 지역아동센터를 연구지로 선정하고 7개월 이상 참여 관찰과 심층 면담을 실시하여 아동들의 일상과 센터의 구성원들 간의 상호작용을 살펴보았다. 본 연구는 질적 사례연구로 현상학적 방법에 기반하여 아동들의 일상을 시간, 공간, 활동 3가지 차원에서 이해하고 이를 ‘돌봄’과 ‘배움’의 관점에서 범주화하였다. 그 결과, 시간 차원에서 지역아동센터는 가정과 학교를 보완하는 ‘중간지대’로서 ‘돌봄’과 ‘배움’을 지원하였다. 공간의 차원에서 센터의 공간은 다양한 용도로 사용되지만 때때로 서로의 활동 공간을 침해해야 하는 경우가 발생하였다. 활동 차원에서 저학년, 고학년 학생들이 함께 다양한 프로그램 활동에 참여하며 새로운 것을 배우고, 서로 협력하면서 배움의 영역을 넓혀 갔다. 그러나 프로그램이 과도하게 많이 운영되고 있어 아동들은 프로그램 활동을 충분히 음미하고 몰입하지 못하는 경우가 많았다. 전반적으로 지역아동센터는 가정-지역아동센터-학교 중간지대로 방과 후 아동들의 ‘돌봄’과 ‘배움’의 장이 될 뿐 아니라 방과 후 휴식, 쉼을 경험하는 공간이며 다양한 구성원들과 만남을 통한 ‘협력적 배움’의 공동체로서의 역할을 수행하는 것으로 나타났다. The purpose of this study is to describe the daily experiences of children in child community centers from the perspectives of ‘caring’ and ‘learning’, and to explore the educational role and limitations of community child centers based on the perspectives. Two child community centers were selected as research sites, and participation observation and in-depth interviews were conducted for more than seven months to observe children's daily lives based on the interaction between the children and other members of the center. This study is a qualitative case study, understanding children's daily lives in three dimensions (‘time’, ‘space’, and ‘activity’) based on phenomenological methods, and categorizing them in terms of ‘caring’ and ‘learning’. As a result, in the ‘time’ dimension, the child community centers support ‘caring’ and ‘learning’ in the 'middle ground' between home and school. In the ‘space’ dimension, the space in the center is used for a variety of purposes, but sometimes it is necessary to encroach on each other's space of activity. In the ‘activity’ dimension, the children participate in various program activities, learn new things, and cooperate with each other to expand the scope of learning. However, there are cases where children are unable to concentrate on program activities due to overrun programs. Accordingly, community child centers are not only places for ‘caring’ and ‘learning’ after school, but also places to experience rest after school, suggesting the possibility of being a community of ‘cooperative learning’ through encounters with various members.

Nonlinear spring element was imported into explicit finite element program for vehicle crash analyses. Axial-crush and bending-collapse of the box beam were expressed by nonlinear spring element in combination with Belytschko beam element, using axial crush and bending collapse theories. Some verifications were compared with those of commercial finite element code, PAMCRASH. Shell models and nonlinear spring models for box beams were analyzed for axial crush and bending collapse and the results of the latter were on good accordance with those of the former.<br/>

이란 사파비왕조(1501~1722) 청화도기에 보이는 중국 수출자기의 영향

朴信喜(Park Shinhee) 미술사연구회 2013 미술사연구 Vol.- No.27

Following the increase in marine trade in the eighth century, Chinese ceramics emerged as an important product in seafaring trade between East and West. The fragility, weight and volume of ceramics were such that the sea, which offered greater stability and allowed the carrying of heavier loads, provided a more suitable option for transport than land routes. This fact is confirmed by the huge quantities of ceramic shards, dating from the Tang to the Qing dynasties, which had been excavated at the major international marine trading outposts on the way to the West Asia, including the Malay Peninsula, Indonesia, Sri Lanka, India, Iraq and as well as Egypt. Chinese ceramics in the collections of Iran’s Ardebil Shrine and Turkey’s Topkapi Palace Museum, moreover, offer us some idea of the large quantity in which they reached Iran and neighboring countries. Chinese ceramics were unfailingly copied in every region that they reached, offering further proof of the high demand for them. This study explores the influence, divided into four distinct periods, of Chinese export porcelains on blue-and-white wares of the Safavid Dynasty(1701~1722), the most powerful Persian political entity since the Sasanian Empire. This period saw the production of the finest and most advanced pieces in the history of Islamic ceramics; it is also the period that showed the greatest influence from Chinese export porcelains. The study begins by examining the various styles of Chinese export wares that reached Persia at the time, their forms and routes by which they reached West Asia, in order to explain their particular characteristics. Chinese export wares reached the Safavid Dynasty during the late-Ming and early-Qing dynasties by three routes: tributary trade; trade via European East India companies; and through trading by hawkers at major international trading ports in Southwest and Southeast Asia. Safavid blue-and-white wares imitating the Chinese export wares that reached Persia via these three routes can be divided into the following four periods, according to different characteristics. The first period, which spans the 16th century, is that during which blue-and-white wares inherited characteristics from those of the preceding Timurid Dynasty. The second period, in the first half of the 17th century, saw unprecedented support for the arts on the part of the Safavid Dynasty. The third, in the second half of the 17th century, saw a decline in royal authority but an emphasizing of tradition and independence in Persian culture, while the fourth period spans the end of the 17th and beginning of the 18th century and saw the collapse of the Safavid Dynastye amid economic difficulties, religious persecution, chaotic public sentiment and threats from neighbouring countries, accompanied by the influence of new porcelains from the Qing Dynasty. Finally, the study attempts to explain the circumstances that allowed the potters of the Safavid Dynasty to produce ceramics similar to those of China and which were of a higher quality than those in other West Asian countries at the time and of previous eras.

본 연구는 학업 및 취업스트레스를 많이 받고 있는 대학생을 대상으로 이들이 인식한 학업 및 취업스트레스와 대학생활적응 관계에서 회복탄력성과 사회적지지의 매개효과를 검증하는데 목적을 둔 실증적 조사연구이다. 본 연구의 목적을 달성하기 위해 광주 C대학교에 재학 중인 중학교 1~4학년 246명을 연구대상으로 선정하여 2019년 12월 30일부터 2020년 1월 3일까지 4일 간 설문조사를 수행하였다. 수집된 설문자료는 SPSS 프로그램을 이용하여 빈도분석, 신뢰도 검증, 상관관계분석, 중다회귀분석을 실시하여 다음과 같은 연구결과를 도출하였다. 첫째, 지방대학생이 인식한 학업 및 취업스트레스, 회복탄력성, 사회적지지, 대학생활적응 간의 유의한 관련성이 나타났고, 학업 및 취업스트레스, 회복탄력성, 사회적지지지 변인은 대학생활적응을 예측하는 유의한 변인으로 나타났다. 둘째, 학업 및 취업스트레스와 대학생활적응 관계에서 회복탄력성과 사회적지지의 부분매개효과는 유의한 것으로 나타났다. 따라서 대학생들의 학업 및 취업스트레스를 완화 및 조절하고 대학생활적응을 향상시킬 수 있도록 대학 차원에서 이들의 회복탄력성 강화 프로그램을 도입하고 지도교수를 비롯한 대학 내 안전한 사회적지지 체계를 구축해 적용하는 방안을 적극적으로 검토할 필요가 있을 것이다. This study is an empirical investigation into the mediation effects of resilience and social support on the relationship between study and job-seeking stress and adaptation to college among students at a university. For the study, 246 students who are attending University C in Gwangju, South Korea, were selected as subjects and took survey from December 30, 2019 until January 3, 2020. The collected data from the questionnaire were analyzed by using SPSS based on frequency analysis, reliability test, correlation analysis, and multiple-regression analysis. The findings were as follows: first, significant correlation was found among the study and job-seeking stress, resilience, social support, and adaptation to college, as perceived by provincial university students, and study and job-seeking stress, resilience, and social support were significant variables that predict the students adaptation to college. Second, in the relationship between study and job-seeking stress and adaptation to college, resilience and social support had significant partial mediation effects. Therefore, in order to mediate and control study and job-seeking stress of students at provincial universities, the universities will need to introduce resilience enhancement programs and establish a safe social support system based on professors and others.
