Pedestrians not only walk along roads, but also pass through buildings or across open spaces. This study defines theseunusual walk routes as social path. Social path is an informal pedestrian route that is not considered in a pedestriannetwork, even though it should be regarded as pedestrian route considering the fact that many people actually use this path. In response, current study related to travel behavior cannot evaluate properly due to lack of consideration for realistic travelbehavior such as social path. In order to deal with this situation, this study analyzes the effect of social path at two complexcenters in Seoul. Evaluation indices are service area analysis and urban network analysis which is one of the spatialnetwork analysis. In particular, we subdivide the network into three steps by the level of network building and analyze eachstep. As a result, it is revealed that step three which includes social path shows the greatest improvement in pedestrianaccessibility. In this regard, we confirm that social path should be considered when evaluating pedestrian accessibility infurther studies. Furthermore, a lot of undervalued facilities will be re-appraised in the field of travel behavior. 보행자는 일반적인 보행로를 따라 이동할 뿐만이 아니라 건물을 통과하거나 넓은 공간을 가로지르는 등 다양한 방식으로이동한다. 본 연구는 이러한 일반적이지 않은 보행 경로를 social path로 정의하여 보행 네트워크 중 하나로 정의하였다. Social path는 일반적인 보행 네트워크상에서는 구현되지 않지만 현실에서는 많은 사람들이 이용해 통행하는 경로를 의미한다. 기존의 보행 접근성 연구에서는 이러한 현실적인 통행 패턴을 구현하지 못함으로 인해 보행로 및 시설의 보행 접근성을올바르게 평가하지 못하였다. 이를 개선하기 위해 본 연구는 서울의 코엑스와 고속터미널 지역을 대상지로 선정하여 socialpath의 효과 분석을 수행하였다. 효과 분석을 위해서는 서비스 권역 분석과 UNA기법을 활용하였다. 특히, 네트워크의 구현정도를 3step으로 구분하여 각 단계별 효과를 분석하였다. 그 결과, social path가 추가된 step3에서 보행 접근성 개선 효과가가장 뛰어난 것으로 나타났다. 이를 통해 향후 관련 연구에서 보행 접근성을 평가하는데 있어 social path를 고려해야 한다는필요성을 확인 할 수 있었다. 또한 social path로 인해 현재 보행 접근성 평가 측면에서 저평가를 받는 다양한 시설물들이 주목받을 것으로 기대한다.

Analysis on the Value Chain Structure of Musical Satisfaction Using Path Analysis Kim, Haw-rye/Kwon, Byung-woong/Kim, Youn-tae Path analysis is a form of statistical analysis used to examine therelationships betweenvariablesand its advantage is to enable direct effect, indirect effect and spuriouseffect which are hard to identify by regression analysis. Using path analysis, this study examined the value chain structure of musical elements such as distribution, planning, production and consumption which are expected to affect musical satisfaction. The selected population was Seoul Citizens who watched musicals at least one time and, through random sampling, 250 were selected as sample at eight musical theaterslocated in Daehakro, Chungmuro, etc. in Seoul. Among the questionnaires collected from the 250 samples, 212 were used for this study except 38 unfit for analysis. Survey is composed with total of 24 questions which include 6 demographic questions, 17 audience tendency questions and 18 satisfaction questions. We made value chain structure analysis by dividing each level of satisfaction in planning, manufacturing, distribution and consumption and executing subsequent factor analysis in those satisfaction questions. Study results after reliability analysis of 18 satisfaction level questions showed high level of 0.893 reliability coefficient and therefore, we can tell there exists high level of internal consistency in each factor.

유창호(Yu, Chang Ho),나주몽(Na, Ju mong) 한국도시행정학회 2014 도시 행정 학보 Vol.27 No.2

국가와 지방자치단체에서는 자전거 이용률을 제고하기 위해서 자전거 인프라 구축에 많은 비용과 시간을 투자하고 있다. 하지만 많은 국가정책이 그러하듯이 공급자 위주로 정책이 추진되고 있다. 자전거 정책에 있어서도 공급자 위주의 정책이 수립 시행되고 있는데 최근 개통된 4대강 국토 종주 자전거길 역시 그러한 정책과정을 통해 신속하게 조성되었다. 이렇게 공급자 측면에서 조성된 4대강 자전거길의 이용자가 증가하고 있으나 이용자 측면에서 바라본 실질적인 만족도에 대한 연구는 미진한 실정이다. 이에 이용자 관점에서 레저형 자전거길 이용 만족도 영향요인을 분석하여 자전거길 이용 만족도 제고를 위한 개선안을 제시하고자 한다. 이를 위해 4대강 국토 종주자전거길 중에서 영산강 자전거길을 대상으로 자전거길 이용자의 만족도 조사를 수행하였다. 이용 만족도 조사 방법으로는 선행연구와 표적집단면접을 통해 만족도 측정 항목을 3가지 항목 경관 만족도, 부대시설 만족도, 주행환경 만족도로 최종 선정하여 이를 토대로 설문조사를 실시하였고 조사결과를 이용하여 요인분석을 실시한 다음 신뢰도 분석과 상관분석을 통한 자료 검증을 수행하였다. 요인분석을 통해 확인된 3개 요인을 토대로 다중회귀분석을 수행한 결과 영산강 자전거길 이용 만족도에 통계적으로 유의한 영향을 주는 요인은 주행환경 요인(.474), 경관 요인(.314)로 분석되었다. 이와 같은 분석결과를 바탕으로 영산강 자전거길 이용 만족도 제고를 위해 두 가지 측면에서 개선방안을 제시하였다. 주행환경 측면의 개선방안으로는 노면상태에 대한 개선과 주행안전시설물에 대한 추가설치를 제안하였고 다음 경관 측면 개선방안으로는 자전거길 이용자들이 쉴 수 있는 녹음(그늘)에 대한 추가 설치 및 가로식재상태(조경)에 대한 보완을 제안하였다. In order to vitalize the use of bicycles, central and local governments have invested time and considerable amounts of money constructing bicycle infrastructure. However, as with many policies, this is being promoted as provider oriented infrastructural policy. Recently opened bicycle paths along the 4 major rivers were also constructed from a provider point of view. However, studies on the user satisfaction of leisure-type bicycle paths are absent. This thesis intends to present an improvement plan for analyzing factors affecting the satisfaction of leisure-type bicycle paths from the perspective of users and can improve user satisfaction. For this purpose, among national bicycle paths traversing the 4 major rivers, a user satisfaction survey was performed with the Yongsan River bicycle path as the subject. The satisfaction survey method utilized was developed from the aspect of 3 measurement items based on focuse group interviews and previous studies. The questionnaire survey was conducted by using a questionnaire that had been developed. Factor analysis was performed using the results of the questionnaire and the data was then verified through correlation analysis and reliability analysis. Multiple regression analysis was performed using 3 factors which were the result of factor analysis. Results of this analysis revealed landscape(.474) and cycling environment(.314) as the primary statistically significant bicycle path user satisfaction factors. Based on the results of multiple regression analysis, to increase user satisfaction of bicycle paths, proposals for improvement measures were presented from two aspects. In order to improve the riding environment, it is proposed that additional riding safety facilities are installed and the state of the path surface is improved. In order to improve the landscape, it is proposed that landscaping and facilities to provide shade where the user can rest are supplemented.

Objectives The current study aimed to explore the relationship between a person and its embedded ecological systems using multi-group (primary vs. secondary) meta-path analysis. Through this, the significance of the indirect effect of social-emotional competence was determined in the path model of connecting environmental variables of sense of school community and peer relationship to defending behavior. Finally, we tested whether the mediating effect of social-emotional competence in the entire group differed by school level (primary vs. secondary). Methods A multi-group meta-path analysis was conducted on domestic academic journals (29 articles), master's and doctoral dissertations, and candidates for entry journals (28 articles) from 2007 to June 2021. Two-step processes were performed for meta-path analysis (a) the mean correlation coefficient, that is, a pooled correlation matrix was obtained using the random effect model for the correlation between each study, and (b) direct and indirect effects were examined using meta-path analyses. Results In the meta-path analysis for entire and middle school students, direct and indirect effects were significant in all paths among the sense of school community factor, the peer relationship factor, the social-emotional competence factor, and the defending behavior factor. However, in elementary school students, social-emotional competencies mediated fully the relationship between the sense of school community and defending behavior. Still, social-emotional competence did not mediate the relationship between peer relations and defending behavior. Conclusions This study confirmed that elementary and middle school students had different pathways in the model in which sense of school community and peer relationship impacted the defending behavior through individual social-emotional competence. 목적 본 연구는 또래괴롭힘 방어행동 요인에 영향을 미치는 주요 변인으로 채택된 생태체계와 개인 간의 관계를 규명하고자 초⋅중등 전체와 함께 학교급 별로 다집단 메타경로분석을 실시하였다. 이를 통해 환경 변인인 학교공동체의식, 또래관계가 개인 변인인사회⋅정서역량을 매개하여 방어행동에 이르는 경로에서 각 요인 간 직접효과의 유의성을 살펴보았다. 마지막으로 생태체계 요인과 방어행동의 관계에서 개인이 학교급에 따라 매개효과 차이가 있는지를 살펴보고자 하였다. 방법 이를 위해 2009년부터 2021년 6월까지 국내에서 진행된 학술지(29편) 및 석⋅박사 학위 논문 및 등재후보지를 대상으로(28 편) 다집단 메타경로분석을 실시하였다. 메타경로분석의 순서는 각 연구 간의 상관을 랜덤효과모형을 이용해서 평균 상관값인 합동상관행렬을 구한 후 이를 경로분석의 방법을 이용하여 직⋅간접효과를 살펴보았다. 결과 전체와 중등 집단을 대상으로 한 메타경로분석은 학교공동체의식 요인, 또래관계 요인, 사회⋅정서역량 요인, 방어행동 요인간 모든 경로에서 직⋅간접 효과가 모두 나타났다. 하지만 초등집단에서는 학교공동체의식과 방어행동의 관계에서 사회⋅정서역량은 완전매개효과를 나타냈지만 또래관계와 방어행동의 관계에서는 사회⋅정서역량이 매개효과를 나타내지 않았다. 결론 본 연구는 학교공동체의식과 또래관계라는 환경적 요인이 개인의 사회⋅정서역량을 거쳐 방어행동을 일으키는데 있어 초등과중등학생이 경로 차이가 남을 확인하였다.

Acquisition Path Analysis Method Derived Using Physical Model

Yonhong Jeong,Sunyoung Chang,Dongjin Kim,Hojung Do,Yein Seo 한국방사성폐기물학회 2022 한국방사성폐기물학회 학술논문요약집 Vol.20 No.1

KINAC is trying to build a comprehensive aerial view of the nuclear material balance to predict North Korea’s weapons-grade nuclear material production capacity. We are creating a visualization model for North Korea’s nuclear facilities as part of these efforts. However, information on North Korea’s nuclear facilities is scarce, and it is not easy to consider additional facilities other than those already known. In addition, in the case of a model that targets only exceptional situations, it is not easy to secure objectivity for model validation, so it is necessary to upgrade to a general-purpose analysis tool that can be applied more generally. The following two examples are proposed as an analysis tool that can be a high degree of analysis. The first case is an Acquisition Path Analysis (APA) utilized to introduce IAEA’s State-Level Approach (SLA). The acquisition path analysis aims to find and evaluate the technically possible pathways to obtain nuclear materials for nuclear weapons or other nuclear explosive development. It can be an acquisition route if it is possible to produce at least 1 Significant Quantity (SQ) of weapongrade nuclear material within five years. The assessment of technologically feasible pathways is based on available information about the country’s past and present nuclear cycle capabilities. The second is the IAEA Physical Model. The IAEA Physical Model was carried out to introduce a comprehensive approach to all information on a country’s nuclear activities. It describes and characterizes the technologies and processes expressed at all levels of the acquisition path, depending on the development objectives. The IAEA Physical Model attempts a multi-tiered acquisition path analysis to identify all known technologies and processes in the nuclear fuel cycle, from raw material production to weapon usable material acquisition. Based on this analysis, the IAEA evaluates the signs of nuclear proliferation in a specific country. Based on the two cases discussed above, we intend to derive the following implications and priorities for extending the existing nuclear cycle model to a more general-purpose for a specific country. First of all, the requirements necessary to evaluate nuclear non-proliferation or verification of denuclearization must be at a level that the international community can recognize. In the stage of actual denuclearization verification, since verification will be conducted through the IAEA, a corresponding level of tools and technology will be required. From this point of view, the following is presented as a prerequisite for adding versatility to the existing physical model: It is necessary to derive all processes related to the nuclear cycle and standardize relevant indicators and data. In order to determine the signs of nuclear activity, detailed information on technologies, materials, by-products, and wastes, which are essential for each process, is required. For denuclearization verification, cumulative information from the past to the time point is required, and a comparative analysis of the operation history information of all facilities and the amount of nuclear material is required. To this end, it is necessary to make it possible to trace the history at every point where it can be determined that nuclear material has been diverted so that missing nuclear material can be found. Based on this, it is expected that it can be possible to evaluate a hypothetical threat state, but it is also expected that it will be easy to verify the model through the evaluation of easily accessible domestic facilities.

Transfer path analysis of rumbling noise in a passenger car based on in-situ blocked force measurement

Shin, Taejin,Kim, Yeon Soo,An, Kanghyun,Lee, Sang Kwon Elsevier 2019 Applied acoustics Vol.149 No.-

<P><B>Abstract</B></P> <P>This paper presents the In-Situ blocked force transfer path analysis (BF-TPA) to identify the structure-borne path of rumbling noise in vehicle cabin. The control of rumbling noise is one of the major strategic targets of interior sound quality inside the cabin of a passenger car. To effectively control rumbling noise in a passenger car, the transfer path of the rumbling noise should be initially identified. It is known that the major source of this noise is the combustion force of an engine. The combustion force excites the engine and induces vibrations of the powertrain. These vibrations are then transferred to the body of the vehicle via its structural transfer path. Moreover, the vibrations of the vehicle’s body emit internal vibra-acoustic noise. This noise is often referred to as the rumbling noise due to the structural borne path. If there are structural resonances among the structural paths such as the engine, transmission, mount bracket, suspension, and the vehicle’s body, the rumbling noise could be amplified. To identify the major resonances of the structural transfer path, classical transfer path analysis (CTPA) has been traditionally utilized. The method has a significant limitation in that it is necessary to decouple the substructures to obtain the contact force between individual components and to identify the transfer path of the structure-borne sound. Recently, In-Situ BF-TPA was introduced and this approach does not require the decoupling of the substructures. In this study, we identify the structure-borne path of rumbling sound based on In-Situ BF-TPA in a passenger car. In addition to identification, the passive control method for rumbling sound is presented.</P>

A Study on Preference and Behavior of Forest Path Users

Seo, Yeongwan,Jung, Sanghyun,Jeong, Sooncheol,Kim, Soyeon,Choi, Jungkee Institute of Forest Science 2021 Journal of Forest Science Vol.37 No.3

This study was conducted to grasp users' preferences and behavior of forest paths and to provide basic data for forest path construction in the future. Among forest path users, males and females over 20 years old were surveyed on forest path preferences, motives for visiting, using time and distance, companions, and sources for obtaining information on forest paths. A total of 587 people participated in the questionnaire, and cross-analysis was conducted simultaneously using the SPSS statistical program. In analyzing the preference of forest paths, it was found that male and the general public preferred trekking path for activities while female and foresters preferred forest path for relaxation and healing (p<0.05). As for the motives for visiting forest paths, the response that they visited for a walk/rest was the highest in gender, occupation, and age group. As for the number of annual visits, less than 5 was the highest in overall, and foresters tended to visit forest path more often than the general public, and the number of visits to the forest paths increased with age (p<0.01). The most common route to acquire information about forest paths is the Internet, while the Internet use is relatively low in those over 60s (p<0.05). The response ratio of accompanying their family in visiting forest paths were the highest, while the response in their 20s and 60s was the most in accompanying their friends (p<0.05).

고전읽기 수업의 외국인과 한국인 학생의 학습 변인과 학습효과의 차이에 대한 실증분석

유경애,이재득 한국교양교육학회 2020 교양교육연구 Vol.14 No.3

This study analyzes empirically the relationship between the learning variables and learning effects of classics reading lessons between Korean and foreign students using cross tabulation table analysis, discriminant analysis, regression analysis, and path analysis. As the results of cross tabulation table analysis, even though there is no significant difference in the recognition about the necessity and importance on the classics, foreign students like the classics more than Korean students. Korean student estimated higher than foreign students the classic class in improving the logical thinking, the formation of value of judgement, and the usefulness of movies and discussions. As the results of discriminant analysis, Foreign student also estimated lower than Korean students the value and the usefulness of classic classes. Korean students have more satisfied the learning effects of classics reading lessons. As the results of regression analysis, the recognition on the importance of the classics can affect positively the satisfaction of classics reading class, the expression power, and presentation. While the recognition variable on importance of the classic did not directly affect the learning effects such as necessity of the classics and recommendation intention to friends according to the regression analysis, it indirectly influenced on the learning effects via the mediate variables of the enhancement of presentation and expression power and the value of life according to the path analysis. 본 연구는 우리나라 대학에서 수강하고 있는 한국인과 외국인 학생들을 대상으로 학습자 변인과 고전읽기 수업의 학습효과의 차이성과 연관성 등을 교차분석, 판별분석, 회귀분석과 경로분석 등을 통하여 실증적으로 분석하였다. 교차분석 결과, 한국인 학생과 외국인 학생 간에는 평소 고전의 필요성, 중요성 등에 대한 인식의 차이가 없었으나 외국인 학생들이 고전에 대한 취향이 더 높았다. 수업을 통하여 발표력과 표현력 향상에는 국적별로 차이가 없었으나, 논리적 사고력, 가치관 형성 등과 영화감상과 토론의 유용성 등에서 한국인 학생들이 더 높게 나타났다. 판별분석 결과, 고전 수업의 가치와 유용성에 대해서 외국인 학생들이 더 낮게 평가하고 있으며, 한국인 학생들의 학습효과가 더 높게 나타났다. 회귀분석 결과, 고전의 중요성에 대한 인식이 수업의 학습효과인 그 만족도와 표현력과 발표력에 유의한 향상을 가져왔다. 경로분석 결과, 고전에 대한 인식은 고전수업의 필요성에 직접적인 영향을 미치지 않은 반면, 매개변인들인 표현력과 발표력, 그리고 삶의 가치관 형성 등을 통해 고전수업의 필요성 등에 간접적인 영향을 미치는 것으로 나타났다.

구조방정식 모델과 경로분석에서 측정오차가 경로계수에 미치는 영향에 관한 연구

우종필(Yu, Jong Pil) 한국서비스경영학회 2015 서비스경영학회지 Vol.16 No.3

Structural equation modeling and path analysis have a common character that can simultaneously estimate several causal relationships among variables, but these two technique are categorized by the existence of measurement errors. While structural equation modeling estimates path coefficient without measurement errors of observed variables, path analysis estimates path coefficient with them. To solve this limitation, several statistical techniques which calculating measurement errors in the path analysis model have been introduced, especially, ‘(1-α)×variance’ technique is generally used among them. However, very few empirical studies that examine the impact of ‘(1-α)×variance’ technique on path coefficients have been researched. Based on this issue, in this study, data were classified as 4 samples (2×2) in terms of measurements reliability and variance that influence measurement errors, and then the statistical results of samples were compared. Also, Cronbach"s alpha and composite reliability were used as reliability coefficient individually in ‘(1-α)×variance’ technique. The study shows that the results of ‘(1-α)×variance’ technique in path analysis are much similar to the those of structural equation modeling than those of common path analysis. Especially, as the measurement errors has increased, the path coefficients in ‘(1-α)×variance’ technique has shown accurate results. However, there is no big differences between when cronbach"s alpha used as reliability coefficient and composite reliability used as reliability coefficient in ‘(1-α)×variance’ technique.

유아교사의 이직의도에 대한 직무스트레스와 사회적지지의 메타경로분석

홍희주,최효정 한국유아교육학회 2023 유아교육연구 Vol.43 No.4

This study examines the relationship between job stress and turnover intention, which has been mentioned as a major variable influencing the social support of early childhood teachers, by using meta-path analysis. For this purpose, 42 research articles on turnover intention-related topics published in domestic journals and master's and doctoral dissertations from 2010 to July 2022 were meta-analyzed. The meta-analyzed correlation matrix was used to verify the model of this study, and path analysis was performed. As a result of the analysis, first, it was found that job stress had a direct and positive effect on turnover intention, and showed a medium average effect size. Second, job stress had a direct and negative effect on social support, and showed a medium average effect size. Third, job stress had an indirect effect on turnover intention through social support, and social support partially mediated the relationship between job stress and turnover intention. This study analyzed the turnover intention of early childhood teachers from a comprehensive perspective on the relationship between job stress and social support through a meta-path analysis. Consequently, this meta-analysis is meaningful as it synthesized the relationship between variables and a path analysis based on a structural equation model. 본 연구의 목적은 메타경로분석을 활용하여 유아교사의 이직의도에 영향을 미치는 직무스트레스와 사회적지지의 영향 관계를 검증하는 것이다. 이를 위해 2010년부터 2022년 7월까지 국내 석· 박사 학위논문과 등재 학술지에 게재된 이직의도 관련 주제의 42편의 연구물을 메타분석 하였고, 연구모형을 검증하기 위해 메타분석 된 합동상관행렬을 이용하여 경로분석을 실시하였다. 분석결과, 첫째, 직무스트레스는 이직의도에 정적으로 직접적인 영향을 미치며 평균효과크기는 중간 정도의 효과크기를 보였다. 둘째, 직무스트레스는 사회적지지에 부적으로 직접적인 영향을 미치며평균효과는 중간 정도의 효과크기를 보였다. 셋째, 직무스트레스는 이직의도에 직접적인 영향뿐만아니라 사회적지지를 매개로 간접 영향을 미치며, 사회적지지는 직무스트레스와 이직의도와의 관계에서 부분매개하는 것으로 나타났다. 본 연구는 기존의 연구결과를 종합 분석하는 메타경로분석을 통해 직무스트레스가 이직의도에 미치는 영향과 사회적지지의 매개효과에 대한 종합적인 관점에서 분석하였다는 점에서 의의가 있다.
