        국내 무용심리학 연구의 내용분석

        장윤정 한국스포츠심리학회 2005 한국스포츠심리학회지 Vol.16 No.2

        The purpose of this study was to systematically investigate the trends of research activities in Korean dance psychology. From 'Academic Achievement & Perspectives of Dance Studies in Korea'(Jang & Park, 2005), 85 articles conducted from 1976 to 2004 in Korea were selected. Characteristics of all articles were categorized according to type of participants, research area, research topic, methodology, and statistical utility. The results indicated that most studies used college students(26.5%), middle and high school students(25.9%), and adults(15.35) as participants. With regard to research topic, most studies were focused on dancers' anxiety and stress(27.0%), health-related issues(24.7%), psychological skills for performance enhancement(17.6%), personality(16.5%), and creativity(7.0%). Survey studies were most frequently used by researchers, field experimental research and qualitative research showed gradually increasing tendency. Among statistical analyses used in the studies, descriptive statistics(26.1%), t-test(21.1%), and ANOVA(20.0%) were most frequently used in the studies. Future research directions of dance psychology in Korea were suggested with respect to the results. 본 연구는 지금까지 국내의 체육 및 무용관련학회지에 발표된 무용심리관련 연구물을 대상으로 연구대상의 특성, 연구 주제, 연구방법, 통계분석방법 등을 시기별로 분석하고 향후 무용심리학의 연구방향을 제시하는데 목적을 두었다. 국내 무용심리학 관련연구의 경향을 규명하기 위하여 『한국 무용학 연구의 성과와 전망』(장윤정, 박중길, 2005)의 부록에 수록되어 있는 452편의 무용심리학 관련논문 중에서 무용 및 체육관련 학회지에 공식 게재된 논문으로서 원문 수집(한국학술정보 DB)이 가능한 85편의 연구물을 선정하여 내용분석을 실시하였다. 분석결과, 대부분의 연구들은 대학생(26.5%)과 중고등학생(25.9%) 및 일반인(15.3%)을 대상으로 실시되었고, 연구 주제는 무용수의 불안과 스트레스 (27.0%), 건강심리(24.7%), 수행 향상을 위한 심리기술(17.6%), 성격(16.5%), 창의성(7.0%)의 순으로 나타났다. 연구방법은 주로 심리검사지를 사용한 조사연구(61.2%)가 가장 많았고, 현장실험연구(24.7%), 질적연구(8.2%)와 문헌연구(5.9%) 순으로 이용되었다. 통계분석기법은 기술통계가 전체의 26.11%로 가장 많은 비중을 차지하였고, 다음으로 t-검증(21.1%), ANOVA(20.0%), 회귀분석(10.0%), 상관관계분석(8.3%) 등의 순으로 이용되었다. 분석 결과에서 나타난 문제점은 크게 연구대상의 제한 및 기본적인 정보 누락, 연구주제의 편중, 스포츠심리학이론의 무비판적 수용, 특정 연구방법에의 편중 등으로서 향후 연구대상의 확대, 무용 장면에 맞는 연구주제 개발 및 현장 중심의 연구가 수행되어야 함을 시사하고 있다.

        Enhancement of DNA mediated energy transfer by Mg2+

        장윤정,김종문,이현미,조태섭,Biao,Jin 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.21 No.1

        The excited energy of ethidium transferred to meso-tetrakis(N-methylpyridinium-4-yl) porphyrin(TMPyP) when they are simultaneously intercalated between DNA base-pairs. The minimum number ofbase-pairs between ethidium and TMPyP required for excited ethidium to emit a photonwas 36Å or 10.6base-pairs. The distance was extended to 72 Å or 21.2 base-pairs in the presence of 100mM Mg2+ ionsalthough the conformation of TMPyP complexed with DNA, whichwas investigated by circular and lineardichroism spectroscopy, was unaffected by the presence of Mg2+ ions.

        Comparison of Binding Stoichiometry of [Ru(1,10-phenanthroline)2dipyrido [3,2-a:2',3'-c]phenazine]2+ and its Bis-derivative to DNA

        장윤정,이현미,Il-Bong,Lee 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.12

        A new bis-Ru(II) complex, in which two [Ru(1,10-phenanthroline)2dipyrido[3,2-a:2',3'-c]phenazine]2+ were tethered by a 1,3-bis(4-pyridyl)propane linker, was synthesized and its binding mode and stoichiometry to DNA was investigated by optical spectroscopy including linear dichroism (LD) and fluorescence intensity measurement. The magnitude of the negatively reduced LD signal of the bis-Ru(II) complex in the dipyrido[3,2-a:2',3'-c]phenazine (DPPZ) ligand absorption region appeared to be similar compared to that in the DNA absorption region, which is considered to be a diagnostic for DPPZ ligand intercalation. The binding stoichiometry measured from its LD magnitude and enhanced fluorescence intensity corresponds to one ligand per three DNA bases, effectively violating the nearest neighbouring site exclusion model for classical DNA intercalation. This observation is in contrast with monomer analogue [Ru(1,10-phenanthroline)2dipyrido[3,2-a:2',3'-c]phenazine]2+, which is saturated at the DPPZ ligand to DNA base ratio of 0.25, or one DPPZ ligand per four nucleobases.

        A Fuzzy Approach to Social Worker's Turnover Intention

        장윤정 한국지능시스템학회 2010 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.10 No.3

        This study seeks to find the factors associated with social workers' turnover intention and show us how to manage turnovers by looking for some rules affecting turnover intentions. Our investigation surveying 331 social workers reveals that social workers' turnover intentions are affected by organizational commitment, job satisfaction, and burnout. Our pattern analyses using fuzzy ID3 show that the higher their commitment, the higher their job satisfaction stemming from promotion opportunities, rewards, and personal relations with peers and bosses. In addition, turnover intentions decreases (even if burnouts--the job-related stress--are very serious) when organizational commitment increases. We come to understand that organizational commitment could be a more important variable than job satisfaction and burnouts. Such results suggest that it would be necessary to consider how to improve social workers' organization-wide commitment rather than satisfaction and burnout related to jobs and environments.

        Evaluating integrated land use and transport strategies in the urban regeneration projects toward sustainable urban structure: case studies of Hafen City in Germany and Shinagawa Station in Tokyo

        장윤정,고주연,이승일 서울시립대학교 도시과학연구원 2011 도시과학국제저널 Vol.15 No.3

        Due to the emergence of urban regeneration, there have been many case studies on urban regeneration projects. However, there has been little research on a successful project that may be helpful for the execution of a sustainable urban structure policy. This study analyses the strategies and characteristics of two successful representative urban regeneration projects that aimed toward a sustainable urban structure, from the viewpoint of land-use transport interaction. For this purpose,we conducted a literature review on the theory of sustainable urban structures and land-use transport interaction and analysed the major strategies and planning characteristics of HafenCity and Shinagawa Station area. In this study, we found that two cases considered an integrated approach of land use and transport to achieve sustainable urban structures that also emphasized regional characteristics and planning factors based on the goal of the projects. As a result, we concluded that a sustainable urban regeneration project should be based on integrated consideration in local context, transport systems and regional characteristics.

        Clinicopathologic characteristics of HER2-positive pure mucinous carcinoma of the breast

        장윤정,정혜라,김한나,서유정,Emad,Alsharif,남석진,김석원,이정은,박연희,조은윤,조수연 대한병리학회 2020 Journal of Pathology and Translational Medicine Vol.54 No.1

        Background: Pure mucinous carcinoma (PMC) is a rare type of breast cancer, estimated to represent 2% of invasive breast cancer. PMC is typically positive for estrogen receptors (ER) and progesterone receptors (PR) and negative for human epidermal growth factor receptor 2 (HER2). The clinicopathologic characteristics of HER2-positive PMC have not been investigated. Methods: Pathology archives were searched for PMC diagnosed from January 1999 to April 2018. Clinicopathologic data and microscopic findings were reviewed and compared between HER2-positive PMC and HER2-negative PMC. We also analyzed the differences in disease-free survival (DFS) and overall survival according to clinicopathologic parameters including HER2 status in overall PMC cases. Results: There were 21 HER2-positive cases (4.8%) in 438 PMCs. The average tumor size of HER2-positive PMC was 32.21 mm (± 26.55). Lymph node metastasis was present in seven cases. Compared to HER2-negative PMC, HER2-positive PMC presented with a more advanced T category (p < .001), more frequent lymph node metastasis (p = .009), and a higher nuclear and histologic grade (p < .001). Microscopically, signet ring cells were frequently observed in HER2-positive PMC (p < .001), whereas a micropapillary pattern was more frequent in HER2-negative PMC (p = .012). HER2-positive PMC was more frequently negative for ER (33.3% vs. 1.2%) and PR (28.6% vs. 7.2%) than HER2-negative PMC and showed a high Ki-67 labeling index. During follow-up, distant metastasis and recurrence developed in three HER2-positive PMC patients. Multivariate analysis revealed that only HER2-positivity and lymph node status were significantly associated with DFS. Conclusions: Our results suggest that HER2-positive PMC is a more aggressive subgroup of PMC. HER2 positivity should be considered for adequate management of PMC.

        A Study on Contents for Leisure Travel Survey Applying Gamification

        장윤정 한국관광연구학회 2015 관광연구저널 Vol.29 No.4

        The processes of the collection and database construction of leisure travel data are essential for the establishment of leisure environment plans in urban spaces; or related polices; however, the leisure travel survey method still relies on conducting household surveys through interviewers. With the rapid spread of information and communication technologies, modern technologies, such as GPS devices and smartphones, have been available for over a decade. However, the previous smartphone-assisted travel survey contents developed in different countries do not have a motivating tool to collect data. In particular, leisure travel surveys have been applied to encourage active participation from the travel survey. This paper discusses the contents of gamification as a methodology that promotes motivation for an active engagement in leisure travel surveys for the collection of leisure and tourism trips data assisted by smartphones; we propose issues for consideration when a leisure travel survey should be conducted. Contents that use the methodology of gamification can be categorized into input of socio-demographic data points, satisfaction of residential environments, and travel survey functions. We can apply an integrated travel data collection method of both passive data collection and active data collection. In addition, the ability to modify the input data must be included along with the data input feature. Contents created using the methodology of gamification can also produce the followings; incorporating entertainment and motivation for participation encourages active survey participation, individual travelers can use their personal travel information as a source of creating value.
