김정혜,박종면,오훈일,Kim, Jung-Hye,Park, Jong-Myeon,Oh, Hoon-Il 고려인삼학회 1994 Journal of Ginseng Research Vol.18 No.3

A study was designed to investigate the sorption characteristics of binary mixture of red ginseng powder and maltodextrin(DE-17) or lactose stored at various relative humidities ranging from 52% to 93%. At low relative humilities below RH 67%, the sorption equilibrium was easily achieved, whereas at higher relative humidity values over 75%, all of the mixtures tended to absorb moisture continuously with an increase in storage time. A linear equation of log(dw/dt): a log(t)+ log b was found to be valid between the sorption rate and storage time with respect to storage humilities. A linearity was also found between log(1-Aw) and the amount of water absorbed over the Aw range of 0.52∼0.93 and the slope was affected by the kind of sugar added with that of red ginseng powder and maltodextrin mixture being the smallest.

김정혜(Jung Hye Kim),하기룡(Ki Ryong Ha),전하나(Ha Na Jeon) 한국고분자학회 2012 폴리머 Vol.36 No.3

본 연구에서는 실리카 나노입자의 표면을 실란 커플링제인 bis[3-(trimethoxysilyl)propyl]amine(BTMA)을 사 용하여 개질하였다. BTMA의 가수분해 시간, 농도 및 개질 시간의 변화가 실리카 표면 개질 반응에 미치는 영향을 Fourier transform infrared spectroscopy(FTIR), elemental analysis(EA) 및 고체 상태 cross-polarization magic angle spinning(CP/MAS) nuclear magnetic resonance spectroscopy(NMR)법을 사용하여 분석을 수행하였다. 연구 결과 BTMA의 가수분해 시간, 농도 및 표면 개질 시간이 증가할수록 3737 cm-1에 나타나는 실리카의 고립 실란올 (isolated silanol) 피크의 세기는 점점 약해지고, 도입되는 BTMA의 -CH2 기에 의한 신축(stretching) 및 굽힘 (bending) 진동 피크는 점점 강하게 나타났다. EA 분석을 통한 N 및 C의 함량에서도 같은 경향을 나타내었다. BTMA를 사용한 실리카 입자의 처리 조건 중, BTMA의 농도 변화는 실리카 입자 표면과 반응하는 BTMA의 양에 큰 영향을 미치지만, BTMA의 가수분해 시간 및 표면 개질 반응 시간의 영향은 크지 않은 것으로 나타났다. In this study, we treated silica nanoparticles with bis[3-(trimethoxysilyl)propyl]amine (BTMA) silane coupling agent to modify their surfaces. We investigated the effects of BTMA hydrolysis time, BTMA concentration and BTMA treatment time on the degree of silanization reaction of silica nanoparticles. We used Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA) and solid state cross-polarization magic angle spinning (CP/MAS) nuclear magnetic resonance spectroscopy (NMR) to obtain quantitative data. We found the decrease of isolated Si-OH peak intensity at 3747 cm-1 and the increase of -CH2 stretching and bending peaks with increasing hydrolysis time, concentration and treatment time of BTMA. EA analysis results also supported this trend. We found a strong effect of BTMA concentration on the degree of silanization of the silica particles, but weak effects of the hydrolysis time and the treatment time.

The purpose of the study was to comprehensively examine the relationship between physical activity participation of people with disabilities and their mental well-being through a meta-analysis. The analysis included academic journals and dissertations that have analyzed mental well-being for people with disabilities participating in physical activity in Korea from 2005 to 2020. After a total of 76 research papers were selected during the preliminary investigation, the papers that didn’t have clear indication which were the information required to compute the effect sizes, were excluded during the review of the individual paper. The remaining 22 papers were used to extract 372 effect sizes for the analysis. The random-effects model of the meta analysis was used along with the variable-level and research-level analyses at the same time as the analysis methods. The conclusions drawn through the above process were as follows. First, the positive effect sizes of the independent variables on mental well-being were exercise addition (g=1.605), social support (g=1.533), and life sports participation (g=1.522), while the negative effective sizes were leisure constraint (g=-.669) and loneliness (g=-.440). Second, as a result of the research level analysis, the overall effect size of the 22 studies was found to be g=.525. Third, as a result of the publication bias review, 372 individual studies that verify the relationship between mental well-being of the people with disabilities and their participation in physical activities only suggested the high effect sizes. After the adjusted effective sizes were calculated through the Trim and Fill method, fhe Funnel Plot became symmetrical when a total of 71 individual studies were inserted. Also, the average effect size was decreased from g=.419 to g=.298.

Art education is one of core subjects that help students develop creativity and its key task is to present active approaches to the development of creativity on the field of teaching. But, art education based on this idea has been neglected on the field of schooling due to factors of academic environment in curriculum and class hours. The essence of art education is not merely in cultivation of esthetic emotion and training of professional artists but in cultivation of artistic gift, ability and creativity inherent in everyone. This research is aimed to double the effect of creativity development through the use of objects in art class for first-grade middle school students. In addition, it focuses on seeking practical and concrete ways for them to participate in art class. The effects of art education through the use of objects are as follows. For starters, the use of objects is very effective in drawing interests from students as it is linked directly with their daily lives. Moreover, it is possible to have students participate in art class by encouraging them to look for objects used in schooling for themselves, The use of objects in art education is principal media of schooling that provide activities in which students can conceive their own way of self-expression by accepting diversity and variability and at the same time, it can promote creative thinking. They come to have a fresh approach to a problem on the basis of various information and ideas with the form of expression called the object. Through this research on the basis of the above effects, we find that art education through the use of objects can extend the activities from simple painting or making things to visual and tactual experience with objects. Besides, it offers concrete ways to maximize creative expression of learners through idea exploration and elaboration process by help of the method for creative solution for a problem.
