Purpose: The purpose of this study was to determine the effectiveness of direct and indirect methods of contract-relax techniques in proprioceptive neuromuscular facilitation (PNF) stretching for improving hamstring flexibility. Methods: Twenty-six subjects were randomly assigned to either a direct contract-relax technique group or an indirect contract-relax group. For each group, stretching intervention was performed three times a week for a period of two weeks, with 12 seconds for the contraction and 10 seconds for the relaxation per once. The direct contract-relax technique for hamstring flexibility was applied by asking the subject to press down on the shoulder of the trainer in the straight leg-raising position. Conversely, the indirect contract-relax technique was performed by raising the leg with resistance. To facilitate a comparative analysis of hamstring flexibility between the two groups before and after the stretching intervention, two-way repeated ANOVA was performed. Hamstring flexibility for each group was measured using a passive straight leg-raising test. Results: The results showed significant improvement in hamstring flexibility for all subjects in the two groups. However, there was no significant difference between the groups. Conclusion: In conclusion, both direct and indirect contract-relax techniques are confirmed to be useful for improving hamstring flexibility. The choice of suitable technique has to be made individually according to the condition of each subject.

김난영,Kim, Nan-young The Korea Institute of Information and Commucation 2018 한국정보통신학회논문지 Vol.22 No.9

여행사를 둘러싼 경영환경은 급속도로 변화하여 왔으며 이는 정보통신기술의 성장과 무관하지 않다. 특히, 최근까지 인터넷을 다소 소극적 차원에서 활용했던 한국의 여행사들은 글로벌 온라인 여행사들이 한국 여행시장을 빠르게 잠식해나가는 것에 큰 위협을 느끼고 있다. 이러한 상황을 고려하여 본 연구에서는 정보통신기술이 한국 여행사 경영환경에 미치는 영향력을 중점적으로 분석하고 이러한 분석을 토대로 한국 여행사의 전략적 대응방안을 제시해 보았다. 첫째, 글로벌 관광상품 유통구조에 대응한 플랫폼 개발에 박차를 가해야 한다. 둘째, 빅 데이터를 여행사 경영에 적극적으로 활용할 필요성이 있다. 셋째, 관광 블로그 마케팅 전략을 적극적으로 활용한다. 마지막으로 고객 개인별 더 전문화된 관광 컨설팅 서버스를 제공함으로써 현재 직시한 문제점들을 풀어나가야 할 것이다. Korean travel agencies that have been utilizing the Internet passively feel threatened as global online travel agencies are quickly permeating the Korean travel market. Under these circumstances, this study conducted a focused analysis on how ICT affects the business environment of travel agencies. Based on the analyzed data, it also presents coping strategies for the Korean travel agencies. First, it is imperative to accelerate platform development to counteract the distribution structure of global tourism products. Second, it is essential that travel agencies actively utilize big data, the new paradigm of technology where data are generated at high speed, high volume, and for numerous purposes. Third, it is necessary to actively utilize a travel blog marketing strategy. As a communication tool for travel agencies, the continuing development of the Internet highlights the usefulness of marketing activities using blogs. Finally, it is essential to provide each customer more specialized travel consultancy.

Statement of problem : Porcelain restorations are widely used in restorative dentistry with a high degree of general success. However, porcelain is brittle and may fracture intraorally. Sometimes a repair may be attempted using composite resin and bonding system available. Color stability of porcelain repair resins affects esthetics and prognosis of prosthesis, so that provides important criteria for the choice of porcelain repair resins. Purpose : The purpose of this study was to investigate the color stability of composite resins used widely as porcelain repair system. Materials and method : Composite resins used for this study were Carisma(Kulzer, Germany), Tetric ceram(Ivoclar, Liechtenstein), Filtek Z250(3M, USA), and Arabesk Top(VOCO, Germany). Thirty disc-shaped specimens($10{\times}2mm$) were fabricated from each composite resin. Color changes of specimens after treatment using thermocycling system(KD-TCS30, Kwang-duk F.A. Korea) and after immersion in methylene blue(0.05% by Wt) were measured with colorimeter(Model Tc-6Fx, Tokyo Denshoku Co.) and obtained data were analyzed. Results and Conclusion: The results obtained from this study were as fo11ows. 1. The color change of Filtek Z250 was lesser than those of Tetric ceram and Arabesk Top after thermocycling (12000 times). 2. All of the composite resins in this study showed increase of color change according to increase of thermocycling frequency. 3. After treatment with methylene blue, the color change of Arabesk Top was greater than those of Carisma and Tetric ceram, and Tetric ceram was more stable than others.

김난영(Nan Young Kim) 한양대학교 관광연구소 2012 觀光硏究論叢 Vol.24 No.1

아산시의 관광은 시간 소비형 실버관광객들에 의해 주도되고 있는 가운데, 관광시장의 다각화를 추구하기 위해 보다 차별화된 관광 이미지 구성을 위한 노력의 필요성이 제기되고 있다. 이러한 시점에서 본 연구에서는 아산시의 이미지를 구성하고 있는 인지적 이미지, 정서적 이미지, 전반적 이미지는 어떠한 영향 관계를 나타내는지 조사하였다. 분석결과 아산시의 인지적 이미지는 6개 유형으로 구분되었으며, 이러한 인지적 이미지는 정서적 이미지와 전반적 이미지에 부분적으로 정(+)의 영향을 미치며, 정서적 이미지는 전반적 이미지에 정(+)의 영향을 미치는 것으로 나타났다. 또한, 인지적 이미지와 전반적 이미지 관계에서 정서적 이미지가 부분적인 완전매개 역할을 수행하고 있는 것으로 나타났다. 이러한 분석결과를 바탕으로 몇 가지 시사점을 제시하였다. In recent years Asan tourism has been mainly led by elderly tourists. In the mean time, the need for diversifying tourism services has been brought in as well in order to make a distinctive tourism image for Asan. The purpose of this study is to examine the relationship of three types of images: cognitive image, affective image and the overall image of Asan. The findings of this study identify six cognitive image types and these factors partly have a positive influence on both affective image and overall image. Affective image has a positive influence on overall image. Furthermore, the affective image partly has a perfect mediating effect on the relationship between cognitive image and overall image. The results suggest several managerial implications.

Kim, Nan-young(김난영) 서울행정학회 2016 한국사회와 행정연구 Vol.27 No.3

이 연구는 정책도구, 일선행정, 집행 환경으로 구성된 정책성과 결정모형을 설정하고 무엇이 정책 성과를 결정하는 지를 규명하는 것을 목적으로 한다. 분석대상 정책 사례는 2000년대 이후 교육분야에서 가장 중요한 정책 중의 하나인 창의교육정책이다. 행정데이터와 191개 고등학교 교사 대상 설문조사 응답자료를 사용하여 분석한 결과 정책도구의 유형에 따라 성과가 달랐다. 수업에서 창의교육방법의 사용비중, 학생평가점수 중 수행평가의 비중으로 측정한 정책성과에 대해 교과서 양 감소, 블록타임제 등 교육과정 규제는 긍정적 영향을 주었지만 창의교육관리 보조금과 교과교실제 시설 보조금의 영향은 통계적으로 유의미하지 않았다. 또한 일선행정에서 교사의 전문성과 창의교육에 부합한 학교 관리의 성과에 대한 영향은 통계적으로 유의미하고 그 방향은 양이었다. 집행환경에서는 교실규모, 부모의 지원의 성과에 대한 영향은 통계적으로 유의미하지 않았으나 대학입학시험(수학능력고사)에서 차지하는 비중이 높은 과목일수록 성과에 부정적 영향을 주었다. This article examines the effect of policy tools, street level administration and implementation condition on policy performance in creativity education policy in Korea using both secondary administrative data and survey data gathered from 191 higher middle school teachers. The findings suggest that the impact of policy tools varies according to type: while curriculum regulation has statistically positive and significant relationship with performance, neither facility improvement grant nor creative management grant does. It is also suggested that street level bureaucrat expertise and school management are positively associated with performance. The article concludes with a discussion of the impact of policy tools, street level administration on policy performance.

김난영(Nan-Young Kim),김영국(Young-Kuk Kim),배기자(Ki-Ja Bae),최재호(Jae-Ho Choi),문제학(Jea-Hak Moon),박근형(Geun-Hyung Park),오덕환(Deog-Hwan Oh) 한국식품영양과학회 2005 한국식품영양과학회지 Vol.34 No.6

식품 산업에서 발생되는 부산물의 가치를 재고하는데 있어서 머루 종자 에탄올 추출물을 대상으로 free radical 소거능을 탐색하여 머루종자의 기능성을 찾고자 본 실험을 수행하였다. 그 결과, 추출수율은 에탄올 농도, 추출온도 및 시간에 따라 전반적으로 4~12%를 나타내었으며 90% 에탄올로 70℃에서 12시간 추출한 추출물의 수율은 11.9%로 가장 높았지만 free radical 소거능(RC_(50))은 40.42 ㎍/mL로 나타났다. 그러나 70% 에탄올로 70℃에서 6시간 추출을 하였을 때 추출수율은 6.9%를 나타냈지만 RC_(50)은 20.93 ㎍/mL로 가장 높았고 총 페놀 함량도 330.71 mg GAE/g으로 가장 높게 나타났다. 본 연구결과, free radical 소거능이 높을수록 총 페놀 함량이 가장 높은 것으로 나타났으며 머루종자 에탄올 추출물의 free radical 소거능이 총 페놀 함량과 밀접하게 관련이 있는 것으로 나타났다. 한편, 70% 에탄올을 70℃, 6시간 추출물로부터 유기 용매별로 순차적으로 분획한 결과, 추출수율은 폴리페놀 화합물들을 많이 함유하고 있는 ethyl acetate 분획층에서 약 28%로 높았으며, RC_(50)도 ethyl acetate 분획층에서 8.65 ㎍/mL로 가장 높았고 총 페놀 함량도 ethyl acetate분획층에서 636.77 mg GAE/g으로 가장 높게 나타났다. Wild grape is a traditional medicine plant in north-eastern part of Asia and has been known to have healing properties for various illnesses. This study was to determine the optimum extraction condition and antioxidant activity of ethanol extracts of wild grape (V. coignetiae) seed. Also, organic solvent fractions of hexane, chlo- roform, ethyl acetate and butanol were obtained from the ethanol extract of wild grape seed at different temperatures. Total ethanol extraction yield of wild grape seed ranged from 4% to 12% depending on the ethanol concentration, extraction temperature and time condition. The highest extraction yield of 11.9% was obtained at 90% ethanol condition for 12 hour at 70℃. However, the strongest free radical scavenging effect (RC_(50)) with 20.93 ㎍/mL was observed in 70% ethanol extract of wild grape seed extracted for 6 hour at 70℃, while RC_(50) with 40.42 ㎍/mL was observed in 90% ethanol extract for 12 hour at 70℃. Antioxidant activity of ethanol extracts of wild grape seed increased as total phenol contents increased. Among each fraction obtained from organic solvents, ethyl acetate fraction was found to have the strongest RC_(50) (8.6 ㎍/mL) and 636.77 mg GAE/g phenol contents.

This study aims to analyze various factors in regulatory administration that can cause inconvenience and complaints. For this purpose, this study organized a conceptual framework for analyzing the factors based on a literature review, and conducted a survey of the perceptions of both civil petitioners and civil servants. In particular, compared to existing studies, this study is significant in that the survey included civil petitioners who had been directly involved in regulatory administration. According to the analysis, regulatory redundancy and conflict in terms of policy contents, complicated regulatory procedures, and economic burdens to those regulated proved to be the primary factors causing complaints and inconvenience. Also, the fact that there exists departmental selfishness and that there is little coordination among departments proved to be a big challenge to regulatory administration. In addition, the survey revealed that the attitudes and responsibility of street level bureaucrats were very important factors influencing complaints and inconvenience. From the viewpoint of a civil servant, inadequacy of resources such as staff and finances, and a lack of incentives came out as major obstacles to performing regulatory administration. The difference in perception between the two groups was quite big when it comes to the adequacy of legal authority and the accuracy of application of the law, so substantial communication between them is required.
