李熙玉 ( Lee¸ Hee-ok ) 성균관대학교 대동문화연구원 2020 大東文化硏究 Vol.112 No.-
이 논문은 동아시아학술원의 성균중국연구소의 성과를 통해 한국에서의 중국연구의 위상과 연구 인프라를 점검하고 대학부설 연구소의 목표와 방향을 제시하기 위한 것이다. 그동안 한국의 중국 관련 연구소는 중국연구 수요의 폭증에도 불구하고 학문적 방향성을 확립하지 못했고, 이데올로기적 편향이 남아 있었다. 또한, 중국연구의 생태계가 약해 학문적 의제를 기획하는 능력이 부족했고, 연구의 공론장과 플랫폼이 없는 상태에서 융합연구도 제약되었다. 특히 인문학과 사회과학, 학문과 정책, 교육과 연구의 결합을 시도하지 못하는 등 한국형 중국연구, 한국형 중국연구소의 모형을 구축하는 데도 효과적이지 못했다. 이런 점에서 2012년 성균중국연구소는 새로운 중국연구의 거점을 마련하고 새로운 연구 의제를 기획하고 이를 사회로 확산하는 새로운 플랫폼을 지향했다. 실제로 다양한 국제학술회의, 네트워크, 학문과 정책을 결합한 프로젝트 수행 등을 통해 성과를 입증하였다. 그 결과 한국내 싱크탱크 평가에서 중국연구기관으로는 유일하게 랭크되면서 짧은 시간 내 한국의 대표적 중국연구소로 자리잡았다. 이러한 연구소의 성공모형은 예산, 인력, 공간이라는 연구 인프라와 데이터베이스의 구축을 통한 학문적 수월성의 확보, 안정적인 네트워크, 중국연구 의제와 담론을 적극적으로 개발한 결과라고 볼 수 있다. 그러나 향후 성균중국연구소는 대학 내 분과학문과의 융합, 다른 중국연구소와의 협업, 인공지능시대에 대비한 새로운 연구모형의 개발, 동아시아를 넘어 세계적 소통을 향한 노력, 한국형 중국연구 발신의 문제 등이 향후 과제이다. This paper aims to examine the status and research infrastructure of Chinese studies in Korea and present the goals and directions of the university-affiliated research institute through the achievements of the Sungkyun Institute of China Studies (hereafter: SICS) under the Academy of East Asian Studies. So far, Korea's China-related research institutes have failed to establish academic direction despite a surge in demand for Chinese research, and ideological bias has remained. Besides, due to the weak ecosystem of Chinese research in Korea, the ability to plan academic agendas was insufficient, and convergence research was restricted in the absence of a public forum and platform for research. In particular, it failed to build a model of Korean-style Chinese research, failing to combine humanities with social sciences, academics and policies, education and research. In this regard, the launch of the SICS has greatly contributed to establishing a base for new Chinese research, planning new research agendas, and spreading them into society. It has been proved through various international academic conferences, networks, operation of various activity programs, and carrying out projects combining academic and policy. As a result of these achievements, SICS become one of Korea's leading Chinese research institutes in a short time as it was ranked as the only Chinese research institute in the Korea Think Tank evaluation. The success of the SICS model is the result of an effective combination of research infrastructure―budget, manpower, and space―, database, stable network, Chinese research agenda, and discourse. The future tasks of the SICS for the development of the SICS model will be the multidisciplinary approach, cooperation with other research institutes, development of a new research model for the AI era, efforts toward global communication beyond East Asia.

It is already well known that castration improves marbling quality but exact timing of castration is still highly debated in beef cattle production industry. After castration, blood hormonal changes occur in steer and objective of this study was to investigate the effects of growth hormone (GH) levels on adipocyte differentiation in stromal vascular cells (SVCs) and trans-differentiation into adipocytes in C2C12 myoblasts. Total GH concentrations were measured via enzyme-linked immunosorbent assay (ELISA) in 24 male calves and 4 female calves. Cell proliferation, cellular triglyceride (TG) accumulation, and the cell’s lipolytic capability were measured in C2C12 myoblasts and SVCs. Myogenic, adipogenic, and brown adipocyte-specific gene expression was measured via real-time polymerase chain reaction (PCR) using SYBR green. Serum GH levels were the highest in late-castrated calves. Treatment with 5 ng/mL GH resulted in greater TG accumulation as well as increased CCAAT-enhancer-binding protein (C/EBP)α and peroxisome proliferator-activated receptor (PPAR)γ expression compared to that after treatment with 15 ng/mL GH. Treatment with 5 ng/mL GH also resulted in lower myogenin (myo)G and myoD expression compared to that after treatment with 15 ng/mL GH. The expression of bone morphogenetic protein (BMP) 7 after treatment with 5 ng/ mL GH was higher than that after treatment with 15 ng/mL GH. But carcass characteristics data showed no significant difference between early and late castrated steers. Therefore, our results indicate that castration timing does not seem to be inevitable determinate of carcass qualities, particularly carcass weight and marbling score in Hanwoo beef cattle.

This study was to investigate the role of complementary and alternative medicine in the prevention and treatment of benign prostatic hyperplasia. For this purpose, a randomized, double-blind, placebo-controlled trial was performed over 12 months on 47 benign prostatic hyperplasia patients with average age of 53.3 years and international prostate symptom score over 8. Subjects received either sweet potato starch (group A, placebo, 320 ㎎/day), pumpkin seed oil (group B, 320 ㎎/day), saw palmetto oil (group C, 320 ㎎/day) or pumpkin seed oil plus saw palmetto oil (group D, each 320 ㎎/day). International prostate symptom score, quality of life, serum prostate specific antigen, prostate volume and maximal urinary flow rate were measured. In groups B, C and D, the international prostate symptom score were reduced by 3 months. Quality of life score was improved after 6 months in group D, while those of groups B and C were improved after 3 months, compared to the baseline value. Serum prostate specific antigen was reduced only in group D after 3 months, but no difference was observed in prostate volume in all treatment groups. Maximal urinary flow rate were gradually improved in groups B and C, with statistical significance after 6 months in group B and after 12 months in group C. None of the parameters were significantly improved by combined treatment with pumpkin seed oil and saw palmetto oil. From these results, it is suggested that administrations of pumpkin seed oil and saw palmetto oil are clinically safe and may be effective as complementary and alternative medicine treatments for benign prostatic hyperplasia.

In most marine seismic refraction studies using shots detonated near the sea surface, the location of receivers and shots are usually assumed to be located at the point of deployment and the shot times are accurately known. In the case of bottom shots and receivers, however, the above assumption can be led to big errors in the shot and receiver positions. The errors in the shot and receiver positions can cause severe distort in the interpretation of deep ocean refraction studies. In this study, an inversion algorithm has been developed to reduce the errors in the shot and receiver position. The inversion method has been used to obtain the shot and receiver positions and the shot origin times of a deep ocean refraction seismic experiment which was performed near the Juan de Fuca ridge in 1985. The comparison of two seismic record sections, one using the initial shot and receiver positions and the other using the shot and receiver positions obtained by the inversion algorithm, shows that the seismic signals emerges much more gradually in the latter. This indicated that the posotions of shots and receivers should be relocated using some inversion methods for better interpretation of deep marine seismic refraction studies.
Attenuation Mechanism of Seismic Waves in Young Uppermost Oceanic Crust
Heeok Jung 한국지구과학회 1992 韓國地球科學會誌 Vol.13 No.1
An attenuation profile of young uppermost oceanic crust was obtained using ocean bottom seismometers and explosive sources detonated near the ocean bottom. The quality factor (Q) increased from 6 at the sea floor to 50 at a depth of 500 m. The mechanisms of high attenuation obtained in this experiments was inferred by examining several attenuation mechanisms such as frictional dissipation, viscous shear flow, liquid squirt mechanism and scattering by small pores and large cracks. Comparison of the attenuation value in this experiment and those from other experiments was also used to clarify the mechanism of the high attenuation. Of those mechanisms mentioned above, frictional dissipation, viscous shear flow and scattering do not seem to be the cause of the high attenuation in the uppermost oceanic crust where many small pores and large scale cracks are developed. The most viable mechanism in the young uppermost oceanic crust seems to be liquid squirt mechanism.

This study was performed to determine the effects of dietary calcium (Ca) intake, milk and dairy product intake, and serum vitamin D level on bone mineral density. The survey data from the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES) for adults (3,819 males, 5,625 females) aged > 20 years were examined; osteoporosis was defined according to the standards for Asian populations (T-score < -2.5). The risk for osteoporosis significantly decreased as Ca intake increased; this effect persisted (quartile 4 vs. quartile 1 of Ca intake: odds ratio [OR] 0.66; 95% confidence interval [CI]: 0.50-0.87) even after adjustment for gender, age, and other factors (body mass index, serum vitamin D, menstruation, female hormone intake, menopausal status, and the number of days per week of muscular strength exercise). Additionally, the risk for osteoporosis significantly decreased as the Ca/P ratio increased (quartile 4 vs. quartile 1: OR 0.76; 95% CI: 0.58-0.98). The degree of risk was 0.96 (0.66-1.38) in those who consumed < 1 portion of milk or dairy products daily, and 0.71 (0.53-0.96) in those who consumed > 1 portion per day, compared with those who had zero intake. The risk for osteoporosis significantly decreased as the serum 25(OH) vitamin D level increased. From these results, we advocate an increase in Ca, milk, and dairy product intake, and that serum 25(OH) vitamin D levels be maintained within the normal range, for the maintenance of bone health and the prevention of osteoporosis in adults.
A Meta-analysis of Scaffolding Strategies in Higher Education
( Heeok Heo ),( Min Young Doo ) 한국교육공학회 2016 한국교육공학회 학술대회발표자료집 Vol.2016 No.1
The purpose of this study is to analyze the effect of scaffolding strategies in higher education using meta-analysis. Scaffolding can be defined as instructional support provided by a teacher/ tutor that allows students/tutees to meaningfully participate in and gain skills at learning situations (Belland, 2014). Scaffolding does not only help learners challenge the difficult level of tasks beyond their current capabilities, but also it enhances learners`` cognitive development and meta-cognitive skills. For this reason, the research investigating the learning effects of scaffolding has been extensively conducted for the last 10 years in educational technology field. Although there are accumulated research findings about the learning effects of scaffolding strategies, consistent results on the effect of scaffolding strategies cannot be easily found due to their different research purposes and contexts. In particular, many existing studies classify the types of scaffolding strategies relevant to the research context. However, coherent benefits by the types of scaffolding strategies are not judged clearly for a certain learning purpose. In order to find out the benefits of the type of scaffolding strategies, this study employs a meta-analysis as research methodology. Meta-analysis is a statistical technique of integrating the results of a set of studies including common research questions (Cooper and Hedges, 1994). Meta-analyses only can include certain quantitative studies. Qualitative studies are common in the scaffolding literature. Empirical studies of a variety of designs and methodologies are all of great value, and all can contribute to an understanding of the impacts of scaffolding (Belland et al., 2015). Existing studies on scaffolding strategies published between 2005 and 2015 in national and international levels will be examined in this study. The research questions are as follows: 1. What is the magnitude of the overall effect size for scaffolding strategies in higher education? 2. To what extent do the types of scaffolding strategies influence learning outcomes? 3. To what extent do the types of scaffolding strategies and learning context (online, classroom, and blended settings) influence learning outcomes? 4. What are the reasons for observed differences in effect sizes across studies? For the meta-analysis, the coding scheme of the existing studies will be specified in four domains: 1) research context (e.g., target audience, research purpose, study design) 2) the types of scaffolding strategies (e.g., content-oriented, process-oriented, and meta-cognition) 3) learning context (e.g., online, classroom, and blended settings) 4) learning outcomes (e.g., cognitive, affective and social, psycho-motor domain) The result of the study will be discussed in the conference. The main implications of the study is to provide synthesized information on the effects of scaffolding strategies and further direction in scaffolding research.

Paprika is known to contain polyphenolic compounds that have good antioxidant properties. This study was conducted to investigate the benefits of adding paprika juice of different colors to yogurt and to determine how paprika affects the quality characteristics of yogurt. Stirred yogurt samples supplemented with different levels of red, orange, or yellow paprika juice were inoculated with mixes of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus. Paprika addition decreased the pH but increased titratable acidity, lactic acid bacteria (LAB) counts, total polyphenol content (TPC), levels of vitamin A and C, and antioxidant activity. Proteolysis and viscosity of paprika-containing yogurts were significantly higher than those of the control yogurt without paprika juice (p<0.05). In particular, the viscosity of red paprika yogurt was significantly higher than that of yogurts containing 5% orange and yellow paprika juices (each p<0.05). The antioxidant activity of the methanol extract of the yogurt containing 2.5% orange paprika juice was the highest. Storage at 4℃ for 15 days only slightly altered LAB counts, antioxidant activity, and TPC of paprika yogurt. These results indicate that paprika could be used as a natural food additive for the development of functional yogurts.

제4차 산업혁명에 따른 사회 및 경제 구조의 변화에 대비하는 인재 양성과 교육에 컴퓨팅 사고력을 기반으로 하는 고차적인 문제 해결력, 창의·융합 능력의 증진에 관한 관심이 전 세계적으로 집중되고 있다. 우리나라에서도 2015 개정 교육과정에 따라 초·중학교에서 소프트웨어(SW)교육 역량을 증진하기 위한 교육을 시행하고 있다. 이에 따라 SW교육의 효과 증진을 위한 다양한 연구와 실천이 이어지고 있다. 본 연구에는 SW교육의 핵심 목표인 컴퓨팅 사고력에 초점을 두고 있다. 컴퓨팅 사고력은 문제를 이해하고 해결하기 위하여 컴퓨팅 기술을 활용하는 능력을 말하며, 분석, 설계, 실현, 평가 능력으로 구성될 수 있다. 본 연구의 목적은 학생들의 컴퓨팅 사고력 유형을 분석하고 각 유형의 특징을 살펴보면서 효과적인 SW교육을 위한 시사점을 얻는 데 있다. 이를 위하여, 중학생 2,949명을 대상으로 컴퓨팅 사고력 기반의 문제해결 과정을 조사하고 그 결과를 토대로 학생들의 특성을 군집분석 방법으로 파악하였다. K-means 군집분석을 실시한 결과, 1차 모델로 5가지 유형을 도출하고 유형별로 중학생들의 흥미와 효능감 간의 유의한 차이가 있음을 발견하였다. 한편, 흥미와 효능감을 포함한 2차 군집모델을 중심으로 4가지 유형으로 구성된 군집과 이에 따른 학생의 성별, 지역 규모, 거주지 권역, 선도/일반학교 여부 등에서 유의한 차이를 확인하였다. 도출된 군집 유형은 학생들의 컴퓨팅 사고력 수준을 파악하는 것뿐만 아니라, 하위 능력별 강점과 약점 역량에 따른 교육 방향을 설정하는 데에 활용될 수 있다. The forth industrial revolution leads the social and economic changes which require human to enhance complex problem-solving, creativity, and convergence based on the computational thinking. The Korean national curriculum revised in 2015 highlights the software education for the elementary and middle school students. Since then various research and practices have conducted to improve the quality of software education as focusing on computational thinking. Therefore, the purpose of this study was to analyze the level and patterns of computational thinking of middle school students. Computational thinking is defined by the process of approaching a complex problem in a systematic manner and solving it in the way the computer science experts carry out. It consists of the subsets including the analysis of problem, design of algorithm, execution of solution, and evaluation. This study assessed computational thinking competency of 2,949 middle school students and analyzed their levels and patterns of the competency. The first clustering model including five patterns on computational thinking was derived by the K-means methods and the differences according to students’ interest and efficacy on information education were revealed significantly. Consequently, the second clustering model based on the six variables including four subsets of computational thinking and the two affective variables (interest and efficacy) produced four clusters with the balanced silhouette. Also, students’ demographic characteristics such as gender, the size and division of the residence, the school characteristics were significantly different according to the four clusters. Finally, some implications of the results were discussed for effective software education.
