이 논문은 중국 정주의 도시 공원을 중심으로 여가 관여도, 체험의 질 그리고 행동의도간의 관계를 연구하였다. 총 335개의 설문지를 8개의 정주의 도시공원에서 수집하였다. 조사에 참가한 335명의 주민을 대상으로 설문지를 수집하였고, 데이터 처리과정에서 부분 응답과 일관성 없는 (불일치) 39개의 설문지를 제거하여 분석목적으로 296개의 설문지를 코드화하였다. 연구 분석을 위해서 SPSS 24.0을 이용하였으며 기술분석, 빈도분석, 요인분석, 다중회귀 분석을 하였다. 연구 결과 주민들의 도시공원에서의 체험의 질은 여가 관여도의 자기 체험의 질보다 여가 관여도의 매력요인(유인요소)과 중심성 요인에 더 많은 영향을 받는 것으로 나타났다. 또한 체험의 질을 구성하는 모든 요인들이 도시공원에서 행동의도에 긍정적 영향을 유의미하게 미치는 것은 아니라는 점을 이 연구의 결과는 보여주고 있다. 교육의 질 요인, 심미요인, 회피체험 요인이 행동의도를 예측하는데 중요하다는 점이 연구결과 도출되었다. 반면, 오락 체험의 질은 행동의도와 유의미한 긍정적(+)인 관계를 나타내지 않았다. 도출된 연구결과를 바탕으로 몇 가지 중요한 연구시사점이 제안되었다. This study focused on relationships among leisure involvement, experience quality and behavioral intention in the urban parks. A total of 335 were collected, and during the data refinement process, 39 questionnaires were eliminated from the study due to partial and inconsistent responses. thus leading to 296 usable questionnaires out of 335. In the final result, 296 questionnaires were coded for the analysis purpose. The hypothesized conceptual model was used to analyze the Descriptive Analysis and Frequency Analysis, Exploratory Factor Analysis, and Multiple Regression Analysis using SPSS 24.0. The result indicated this: residents’ experience quality in urban parks depends on more attraction and centrality of leisure involvement than on the self-experience quality of leisure involvement. The results of this study also indicate that not all experience dimensions are important for resulting in positive behavioral intentions to urban parks. The quality of education, esthetic, and escape experience showed a significant predictor of behavioral intentions, while the quality of entertainment experience did not show a significant positive relationship with behavioral intentions.

유선영 ( Yu¸ Sunyoung ),박선혜 ( Park¸ Seonhye ),조해연 ( Cho¸ Heayoun ) 미래유아교육학회 2021 미래유아교육학회지 Vol.28 No.4

본 연구는 네트워크 분석을 활용하여 공립유치원 교사 임용후보자 선정 경쟁시험 교직논술의 특성 및 경향성을 분석하는 데 목적이 있다. 이를 위해 2001학년도부터 2021학년도까지 임용시험에 출제된 교직논술 문항을 분석대상으로 선정하였으며, 워드클라우드, 연결망 시각화, 빈도, 연결정도중앙성, 사이중앙성을 제시하고 주요 핵심 단어를 분석하였다. 연구결과 첫째, 1기(2001-2008학년도)에는 교육, 2기(2009-2012학년도)와 3기(2013-2021학년도)에는 교사가 가장 중요한 단어로 나타났다. 1기에서는 교육, 학교, 학습과 관련된 주제에서 2기와 3기에서는 교사에 관련된 주제가 주로 출제되는 것으로 경향이 변화하였다. 교직논술 시험 문항이 교과학습지도와 관련성이 높으며, 이론과 지식을 복합적으로 통합한 형태로 출제되고 있음을 확인할 수 있었다. 둘째, 2001학년도부터 2021학년도까지 임용시험에서 등장 순위가 가장 높은 핵심 키워드 5개는 교사, 유아, 부모, 교육, 유치원이었다. 각각의 단어들은 매 시기별로 반복해 등장하지만, 연결된 단어들을 살펴보면 중점을 둔 방향이 서로 상이하다. ‘교육’ 중심 네트워크는 1기에서 가장 강조되었다가 상대적으로 점차 등장 빈도가 줄어들었고 3기에는 인성이 새롭게 등장하였다. ‘교사’는 2ㆍ3기로 갈수록 빈번하게 출제되는 경향으로 변화하였고, 3기에서는 교사를 중심으로 부모, 유치원, 유아, 교육, 상담 등 단어가 제시되는 등 교사 전문성 향상 관련 단어들이 나타나 교육 현장에서 경험할 상황이 출제되었음을 알 수 있었다. 이러한 결과를 통해 교직논술 시험이 현장을 토대로 고차원적이고 창의적 사고를 평가하는 방향으로 개선이 필요하다는 시사점을 얻었다. This study aimed to analyze the characteristics and trends of the essay type kindergarten teacher appointment examination questions using network analysis. For this purpose, this study used the essay type examination questions that were carried out from the year of 2001 to 2021. The text network analysis was used for investigate the key words, work clouds, frequency, degree centrality, and between centrality. The results were as follows. First, the main key word in the first term(from the year of 2001 to 2008) is ‘education’. The main key words in the second term(from the year of 2009 to 2012) and third term(from the year of 2013-2021) are ‘teacher’. The topics in the first term was related to education, school, and learning and most of the essay questions in the second and third term were related to teacher. Second, the top frequency key words from the year of 2001 to 2021 were teacher, children, parents, education, and kindergarten. The ‘education’ centered network was most emphasized in the first term, but the frequency of its appearance gradually decreased, and the ‘personality’ newly appeared in the third term. The ‘teacher’ appeared frequently in the second and third term, and the words related to improving teacher professionalism were presented in the third term. Through these results, it was suggested that the essay questions need to improve in the direction of evaluating higher and creative thinking based on the education field.

( Sunyoung Park ),( Kui Young Park ),( In Kwon Yeo ),( Sung Yeon Cho ),( Young Chang Ah ),( Hyun Ju Koh ),( Won Seok Park ),( Beom Joon Kim ) 대한피부과학회 2014 Annals of Dermatology Vol.26 No.3

Background: A variety of hyaluronic acid (HA) fillers demonstrate unique physical characteristics, which affect the quality of the HA filler products. The critical factors that affect the degradation of HA gels have not yet been determined. Objective: Our objective was to determine the characteristics of HA gels that affect their resistance to the degradation caused by radicals and enzymes. Methods: Three types of HA fillers for repairing deep wrinkles, Juvederm Ultra Plus (J-U), Restylane Perlane (Perlane), and Cleviel, were tested in this study. The resistance of these HA fillers to enzymatic degradation was measured by carbazole and displacement assays using hyaluronidase as the enzyme. The resistance of these fillers to radical degradation was measured by the displacement assay using H2O2. Results: Different tests for evaluating the degradation resistance of HA gels can yield different results. The filler most susceptible to enzymatic degradation was J-U, followed by Perlane and Cleviel. The HA filler showing the highest degree of degradation caused by H2O2 treatment was Perlane, followed by J-U, and then Cleviel. Cleviel showed higher enzymatic and radical resistances than J-U and Perlane did. Furthermore, it exhibited the highest resistance to heat and the lowest swelling ratio among all the fillers that were examined. Conclusion: The main factor determining the degradation of HA particles is the gel swelling ratio, which is related to the particle structure of the gel. Our in vitro assays suggest that the decrease in the swelling ratio will lead to a retarding effect on the degradation of HA fillers. (Ann Dermatol 26(3) 357∼362, 2014)

Cotinine-conjugated aptamer/anti-cotinine antibody complexes as a novel affinity unit for use in biological assays

Sunyoung Park,Dobin Hwang,정준호 생화학분자생물학회 2012 Experimental and molecular medicine Vol.44 No.9

Aptamers are synthetic, relatively short (e.g., 20-80 bases) RNA or ssDNA oligonucleotides that can bind targets with high affinity and specificity, similar to antibodies, because they can fold into unique, three-dimensional shapes. For use in various assays and experiments, aptamers have been conjugated with biotin or digoxigenin to form complexes with avidin or anti-digoxigenin antibodies, respectively. In this study, we developed a method to label the 5' ends of aptamers with cotinine, which allows formation of a stable complex with anti-cotinine antibodies for the purpose of providing another affinity unit for the application in biological assays using aptamers. To demonstrate the functionality of this affinity unit in biological assays,we utilized two well-known aptamers: AS1411, which binds nucleolin, and pegaptanib, which binds vascular endothelial growth factor. Cotinine-conjugated AS1411/ anti-cotinine antibody complexes were successfully applied to immunoblot, immunoprecipitation, and flow cytometric analyses, and cotinine-conjugated pegaptanib/ anti-cotinine antibody complexes were used successfully in enzyme immunoassays. Our results show that cotinine-conjugated aptamer/anti-cotinine antibody complexes are an effective alternative and complementary technique for aptamer use in multiple assays and experiments.

Performance Evaluation Index of TRM: A Korean Case for SMEs

Park, SunYoung,Son, JongKu,Seo, JuHwan,Seo, Jinny Asian Society for Innovation and Policy 2013 Asian Journal of Innovation and Policy Vol.2 No.1

There is the need for performance evaluation and the identification of key success factors for utilizing technology roadmaps (TRM), but relevant research does not yet exists in this field. In Korea, the Small and Medium Business Administration has implemented the "Support Program for the Individual Company Technology Roadmaps" to promote the establishment of technology development strategies by SMEs. This study developed the framework and indices for performance analysis, designed and implemented survey for TRM performance analysis, and analyzed TRM performance of the companies that have participated in the above program from 2008 to 2011. This study compared the supported 97 companies and 102 companies not supported and analyzed quantitative and qualitative performance and satisfaction levels among the supported companies to compare low-performance companies and high-performance companies. This study aims to examine the KSF of TRM in terms of input and process. Also we suggested significant insights into the performance of TRM in terms of output.
