본 연구는 직무만족도 변수들의 요인을 분석하기 위하여 한국고용정보원 2005 대졸자 직업이동경로 조사 1차년도 부터 3차년도 자료, 2009 대졸자 직업이동경로조사 1차년도 그리고 고졸자 직업이동경로 조사와 청년패널 자료를 활용하여 분석하였다. 왜냐하면 직무만족을 구성하고 있는 다양한 요인들이 존재하고 있음에도 불구하고 GOMS(대졸자이 동경로조사), HSGOMS(고졸자이동경로조사) 그리고 YP(청년패널) 자료를 기초로 한 다수의 보고서에 서 직무만족도 요인분석 과정에서 합리적이지 못한 부분이 적용되고 있었기 때문이다. 선행 연구들에서 직무만족도는 최소한 내재적 요인과 외재적 요인으로 구분되어 있다는 사실을 확 인하였다. 그러나 본 연구에서는 한국고용정보원 패널 데이터 분석 결과 탐색적 요인 분석에서는 직무 만족도 변수를 내재적 요인과 외재적 요인으로 구분할 수 없었으며, 확인적 요인분석을 통하여 두 개의 요인을 구분할 수 있었다. 그리고 고용패널 선행연구들에서 많이 사용한 전체 변수들을 분석에 이용한 경우를 또 다른 측정 모델로 구성하여 모두 5개의 측정 모델을 구성하였으며, 확인적 요인분석을 통해 모형 적합도를 확인한 결과, 2005 GOMS I, II, III과 2009 GOMS I 모두 일관되게 “인간관계”항목을 내 재적 요인에 포함하여 “직무내용”, “하고 있는 일의 자율성과 권한”, “개인의 발전가능성”항목으로 내재 적 요인을 구성한 모델(2009 GOMS I_3, 2005 GOMS III_3, 2005 GOMS II_3, 2005 GOMS I_3)이 가 장 우수한 적합도 수치를 나타내었다. 따라서 한국고용정보원 패널 데이터로 직무만족도에 대한 구체적인 연구를 진행하고자 하는 경우 탐색적 요인분석을 통하여 직무만족도 요인을 분류하기 보다는 그동안 선행연구를 기초로 내재적 요인 과 외재적 요인으로 구분한 후 확인적 요인분석을 실시하여 내재적 만족도와 외재적 만족도를 구분하 여 분석하는 것이 필요하다. 특히 연구주제가 직무만족도에 초점을 맞추게 되는 경우 본 연구에서 제안 하는 방법을 고려해 볼 필요성이 존재한다고 할 수 있다.

In order to analyzes the factors of job satisfaction variables, This study were analyzed by 2005 GOMS I∼III, 2009 GOMS I, HSGOMS and YP employment panel data. Because despite the fact that there are various factors that make up the job satisfaction, not rational part was being applied in job satisfaction factor analysis from a number of reports on the basis of the GOMS(graduates flyway research), HSGOMS(high school graduates flyway research) and YP (Youth Panel) data . At least, In previous studies confirmed that the intrinsic job satisfaction factors and the extrinsic job satisfaction factors were separated. In this study, however, In that case of Korea Employment Information Service panel data analysis, exploratory factor analysis could not be separated by the intrinsic job satisfaction factors and the extrinsic job satisfaction factors. Just through confirmatory factor analysis was able to distinguish between the two factors. For the relationship of job satisfaction variables prior research has included extrinsic factors, if the configuration of relationships, relationships with colleagues and superiors supervision. However, in the case of Korea Employment Information Institute panel data the relationships is ambiguity whether the relationship is job duties intrinsic relationships or job duties external relationships Therefore, for confirmatory factor analysis three model was constructed. The first model included variables intrinsicl relationships. The second model is included a human relations for extrinsicl variables. The third model did not include any elements in the relationship. In addition, the development potential of individual variables was composed of more than a model in the intrinsic factor. Because through previous research the development of individual potential variables could not be sure that the intrinsic or extrinsic factors. And finally, the fifth confirmatory factor analysis model is measured using the whole lot of variables used in previous studies to analyze employment panel. And through confirmatory factor analysis confirmed the model fitness. The result 2005 GOMS I, II, III and 2009 GOMS I consistently “human relationships”, “job description”, “autonomy and authority of the work, “individuals development potential factors” the configured model intrinsic to the items (2009 GOMS I_3, 2005 GOMS III_3, 2005 GOMS II_3, 2005 GOMS I_3) showed the best fit value.Thus, when you want to proceed to a detailed study on job satisfaction by the KEIS panel data, on the basis of previous studies and to distinguish between the intrinsic job satisfaction factors and the extrinsic job satisfaction factors, it is necessary to analyze a confirmatory factor analysis. Research topic, especially when focused on job satisfaction in this study to suggest that there is a need to consider how you can. The present study is significant that proposed a way for a more systematic analysis of job satisfaction variables in that has been used indiscriminately through the analysis of research data from existing panel data.

Together with the accelerated growth in national economy in the past, concentration phenomena of city populations has begun to actualize a burgeoning need for housing according to the principles of supply and demand, and has cultivated a supplier oriented marketplace. Suppliers started to build highly concentrated apartments to accommodate the flourishing population, which resulted in the aforementioned supply oriented housing environments as opposed to a market acclimated to the predilection of the consumer. However, as the housing market approached its oversupply level, the market vacillated to a consumer oriented market. In direct contrast with the previous supply oriented market, customers in the oversupplied environment possess increased income levels and a greatly aggrandized quality of life, unlike the under-supplied environment, dissatisfaction with the supply oriented apartments were myriad. Gradually these complaints have accumulated to egregious proportions. Living environments in apartment housing are not improving in response to the demand of the consumers, provoking various social complications. So far, in contrast to the number of studies on satisfaction with apartment housing decisions, there are remarkably few studies pertaining to the levels of dissatisfaction in these same areas. Thus, the purpose of this study is to analyze complaint factors of apartment housing and providing basic data for improving the quality of housing environments.

This research is about the determinants of ASEAN foreign direct investment inflow from the perspective of political risk. In this research, a political risk was classified as factor analysis to subdivide and characterize them, using a panel regression analysis to analyze the determinants of foreign direct investment inflow. It attempts to be differentiated by investigating which political factors affects in foreign direct investment inflow. In Chapter 2, we examined the determinants of FDI and trends of FDI in ASEAN and analyzed related previous studies. In Chapter 3, we established a research model for analyzing the determinants of FDI in ASEAN countries, collected data, and described the interpretation of the results. Finally, in Chapter 4, we organized the implications and limitations of this study. In order to subdivide the analysis of research, the research model was analyzed by separating it into total indices of political risk and segmented indices through factor analysis. The analysis result of total indices, political risk has a negative effect on FDI in ASEAN, and a analysis result of segmented indices, both administrative risk and legal risk have statistically significant variables. However, the democratic responsibility of government, which was eliminated from the factor analysis, has no a statistically significant to the inflow of FDI. This research has implications as follows. First, as a region based study, the characteristics of the determinants of FDI that only ASEAN countries have been identified and analyzed. Second, a quantitative research model was constructed through political risk data, and based on this, emerged the importance of political risk as a determinant of FDI. Third, from the perspective of ASEAN countries, the factors of political risk needed to be managed was presented to attract FDI.

The purpose of this study was to develop and validate a measurement tool for assessing university students’ social and emotional competence in the context of a changing higher education environment. To achieve this goal, preliminary items were constructed based on a review of previous studies and expert consultation, and both a pilot test and a main survey were conducted with university students across the country. Exploratory factor analysis revealed that social and emotional competence consisted of five factors, that is to say, self-understanding, self-regulation, relationship management, social adaptation, and emotional adaptation. Confirmatory factor analysis further verified the model’s goodness of fit and construct validity. The results indicated that university students’ social and emotional competence reflects not only developmental characteristics but also the requirements of social and emotional adaptation within university life. Accordingly, the developed scale can serve as an empirical basis for objectively diagnosing students’ levels of social and emotional competence and can provide foundational data for establishing various student support systems, including coaching, career guidance, learning support, and extracurricular programs. Furthermore, by comprehensively understanding social and emotional competence, this study contributes to the design of educational intervention models that promote the enhancement and development of such competencies among university students.

본 연구는 대학 신입생을 대상으로 종교 편견 정도에 따른 다문화 수용성의 차이를 분석하고자 하였다. 이를 위해 대구 소재 대학 신입생 203명을 대상으로 온라인 설문 조사를 실시하였으며, 다문화 수용성 문항은 요인분석을 통해 네 가지 하위 요인으로 도출하였다. 이후 종교 편견 정도에 따라 응답자를 고편견, 중간편견, 저편견 집단으로 구분하고, 각 집단 간 다문화 수용성 하위 요인의 평균 차이를 비교하였다. 분석 결과, 정서적 수용이 두드러진 외국인 유학생 수용 태도 요인에서 집단 간 차이가 가장 뚜렷 하게 나타난 반면, 사실적 문화 지식과 제도 인식을 반영한 요인에서는 차이가 상대적 으로 적게 나타났다. 이러한 결과는 대학 신입생들의 다문화 수용성이 종교적 편견 정 도에 따라 특정 요인에서 더 두드러지게 나타나며, 특히 정서적 태도의 함양이 다문화 교육에서 중요한 과제로 고려되어야 함을 보여준다.

This study aimed to examine differences in multicultural acceptance among university freshmen according to their level of religious prejudice. An online survey was conducted with 203 freshmen at a university in Daegu, and multicultural acceptance items were subjected to factor analysis, resulting in four sub-factors. Respondents were then classified into high-prejudice, moderate-prejudice, and low-prejudice groups based on their level of religious prejudice, and the mean differences of the multicultural acceptance sub-factors across groups were compared. The analysis revealed that the group differences were most pronounced in the international student acceptance factor reflecting emotional receptivity, whereas differences were relatively smaller in the factor reflecting factual cultural knowledge and institutional awareness. These findings suggest that multicultural acceptance among university freshmen is influenced by religious prejudice more strongly in specific factors rather than overall, highlighting the importance of fostering emotional attitudes as a key aspect of multicultural education.

The purpose of this study was to verify the construct validity of the Parenting Attitude Scale of the Integrated Evaluation Parenting Attitude–Stress Test (IE-PAS) by conducting factor analyses of its seven subscales, and to provide basic data for establishing higher-order factors. Data were collected from a standardized sample of 1,241 parents with children aged 3 to 16, and analyzed using SPSS 23.0 and R version 4.4.2. Results from the exploratory factor analysis revealed two factors: positive parenting attitude (autonomy, warmth, rationality) and negative parenting attitude (indifference, inconsistency, rejection, control). The confirmatory factor analysis further demonstrated that the two-factor structure showed acceptable parsimony and model fit. This study is significant in that it explored and confirmed the factor structure inherent in the IE-PAS, thereby supporting its applicability in clinical and counseling settings.

이 연구는 Tankebe(2013)가 최초로 제시한 경찰 정당성 인식의 4 요인 구조를 국내 에서 김소영·엄유진·정재훈(2024)이 3 요인 구조로 수정하여 제안한 모델을 실증적으 로 검증하는 것을 목적으로 하였다. 이를 위해 2020년 10월 성인 서울시민 510명을 대 상으로 한 설문조사 자료를 활용하여 타당성을 분석하였다. 탐색적 요인분석 결과, 합 법성, 절차적 정의, 분배적 정의로 구성된 3 요인 모델이 적절하지 않은 것으로 나타나 병렬분석을 수행하였으며, 그 결과 단일 요인 구조가 타당한 것으로 확인되었다. 이어 탐색적 요인분석에서도 모든 문항이 하나의 요인에 유의하게 적재되었으며, 신뢰도 분 석과확인적요인분석 결과타당도가 확보되었음을 확인하였다. 이러한 분석 결과는 합 법성, 절차적 정의, 분배적 정의가 독립된 요인이 아니라 하나의 통합된 규범적 요인으 로 인식될 수있음을시사한다. 따라서경찰활동의 정당성을강화하기 위해서는 규범적 요인을 분리하여 접근하기보다 통합적으로 반영하는 것이 효과적임을 제안한다. 이 연 구는 규범적인 단일 요인 구조로 구성되는 경찰 정당성 인식의 타당성을 실증적으로 제시하였다는 점에서 학술적·실무적의의가있으며, 향후 표본의 다양화와 반복 검증을 통해 연구를 발전시켜 나갈 필요가 있다.

This study aimed to empirically examine the validity of the three-factor model of perceived police legitimacy proposed by Kim, Eom, and Jung (2024) in South Korea, which was adapted from Tankebe’s (2013) original four-factor structure. Using survey data collected from 510 adult residents of Seoul in October 2020, the study conducted a series of validity analyses. The exploratory factor analysis revealed that the three-factor model—comprising lawfulness, procedural justice, and distributive justice—was not suitable. Parallel analysis indicated that a single-factor structure was more appropriate, and subsequent exploratory factor analysis confirmed that all items loaded significantly onto a single factor. Reliability testing and confirmatory factor analysis further demonstrated strong construct validity. These findings suggest that lawfulness, procedural justice, and distributive justice are not perceived as independent dimensions, but rather as components of an integrated normative construct. Therefore, enhancing police legitimacy may be more effective when normative elements are addressed holistically rather than in isolation. This study holds both academic and practical significance in that it empirically demonstrates the validity of a normative single-factor structure of perceived police legitimacy, and it highlights the need for further development of the research through sample diversification and repeated validation in the future.

This study investigates the changes in factors influencing aircraft utilization based on aircraft types during the pandemic period. The analysis categorizes the periods into three phases: pre-pandemic, during the pandemic, and post-pandemic, while the aircraft types are classified into two groups (C-class and E-class or higher). Utilizing SHAP and Random Forest methodologies, the study analyzes the importance of various factors for each group and examines the significance of differences in importance across the specified periods and aircraft types through group difference testing. The findings reveal that for C-class aircraft, the importance of the USD/KRW exchange rate and the lagging composite index was notably high before the pandemic. However, during the pandemic, there was a substantial surge in the significance of the JPY/KRW exchange rate, and post-pandemic, the importance of economic indicators increased. E-class or higher aircraft exhibited a similar trend, with a significant rise in the importance of the CNY/KRW exchange rate observed after the pandemic. The Kruskal-Wallis test confirmed that most average changes among the groups were not statistically significant, except for the C-class aircraft in the Random Forest analysis. This indicates that there were no substantial changes in the underlying factors between the pre-pandemic and post-pandemic periods, suggesting that the impact of the pandemic on airline fleet utilization extends beyond short-term changes. Furthermore, the findings highlight the need for airlines to enhance their sensitivity to external environments and develop utilization strategies in volatile markets. Additionally, there is a possibility that long-term dependency on network strategies may become more pronounced than reliance on external factors like the pandemic. By providing an in-depth analysis of the pandemic's impact on aircraft utilization, this study contributes to the formulation of effective utilization strategies for airlines navigating an uncertain economic environment.

우리 사회에서 1인 가구의 증가는 전 연령대를 통하여 관찰되고 있으며 이러한 현상은 앞으로 지속해서 나타날 것으로 예측된다. 이 연구는 계속 증가하는 1인 가구 중에서 중년 남성 1인 가구를 대상으로 사회적 자본이 삶의 만족도에 미치는 영향력을 검증하고 향후 삶의 만족도에 관한 정책 집행을 위한 기초적인 자료를 구성하는 것을 목표로 진행되었다. 연구의 데이터는 대구광역시에서 발간하는 대구사회조사(2022) 마이크로데이터에서 추출된 총 521명의 중년 남성 1인 가구로 구성하였다. 연구방법으로는 요인분석과 다중 로지스틱 회귀분석이 활용하였다. 먼저 요인분석으로 사회적 자본을 측정하였다. 또한 다중 로지스틱 회귀분석을 활용해 사회적 자본이 삶의 만족도에 미치는 영향력을 검증하였다. 분석을 위 한 독립변수로는 요인분석을 통해 측정된 사회적 자본과 월평균 가구 소득, 교육정도, 경제 생활 현황 등의 변수를 활용하였다. 그리고 종속변수는 삶의 만족도 정도로 설정하였다. 분 석결과, 사회적 자본이 삶의 만족도에 유의미한 통계적 영향력을 미치는 점을 확인할 수 있었으며 소득, 교육, 그리고 경제생활 현황 변수의 영향력도 확인할 수 있었다. 이 연구는 상대적으로 정책적 지원과 관심이 높지 않은 중년 남성 1인 가구를 대상으로 사회적 자본 이 삶의 만족도 대한 영향력을 검증하여 중년 남성 1인 가구에 대한 정책적 기반 조성과 더불어 사회적 자본 활용의 필요성에 대한 정책적 함의를 제공하였다.

The increase in one-person households in our society is being observed across all age groups and is expected to continue in the future. This study aims to verify the impact of social capital on life satisfaction among middle-aged male one-person households and to provide essential data for future policies related to life satisfaction. The data for the analysis was derived from the Daegu Survey (2022) microdata published by Daegu Metropolitan City, focusing on a total of 521 middle-aged men living alone. The primary analytical methods used in this study were factor analysis and multiple logistic regression analysis. Factor analysis was used to measure social capital. To examine the effect of social capital on life satisfaction, multiple logistic regression analysis was applied. The analysis utilized variables such as measured social capital, average monthly household income, educational level, and economic status as independent variables, with life satisfaction designated as the dependent variable. The results of the analysis confirmed that social capital has a significant statistical influence on life satisfaction, as well as the effects of income, education, and economic circumstances. This study provided insights into the importance of social capital for life satisfaction among middle-aged male one-person households, a group that relatively lacks policy supports and attentions, and highlighted the need for policies to enhance social capital.

Tactical Urbanism is the specialization of place values that utilize idle space and quickly experience policy effects under the premise of a limited use period. Sinchon Box Square is a representative example of tactical urbanism, which has been operated for six years as an urban regeneration technique applied to a declining commercial area, and can identify the change process of commercial space and urban regeneration effect factors in the cycle and temporal flow of commercial areas. In order to analyze the urban regeneration effects of tactical urbanism introduced to Sinchon Shopping District, a declining university commercial district, this study conducted an empirical analysis using a survey and exploratory factor analysis to determine which attributes of perceived factors positively contributed to the policy effects of the Sinchon Urban Regeneration Project. As a result of the factor analysis, the characteristics of tactical urbanism were converged into six factors, which are fashionability, local context, realization of social needs, spatial attractiveness, change flexibility, and environmental changeability, respectively, and the analysis confirmed that they have a statistically significant positive effect on satisfaction. This study proved the research hypothesis that tactical urbanism as a means of urban regeneration affects visit satisfaction and policy effectiveness, and these findings suggest that tactical urbanism is effective as an alternative policy direction as a new urban regeneration method. It is hoped that this study will serve as a starting point for more detailed and diverse empirical research on Tactical Urbanism and urban regeneration projects in the future.

교통관리에서 교통상황을 판단하는 판단지표의 중요성과 필요성은 계속해서 높아지고 있다. 기존 교통상황 판단지표들은 속도, 교통량, 밀도 기반으로 각각의 특성에 맞춰 개발되었지만, 속성별 가지는 문제점과 종합적인 상황을 보여줄 수 없어 모니터링 지표로는 적합하지 않았다. 이에 본 연구에서는 도로 소통상황과 안전도를 판단하는 지표들을 통합하여 모니터링에 적합한 통합지표 개발을 목표로 하였다. 교통상황의 변화를 판단할 수 있고 안전도를 판단할 수 있는 지표들을 검토하고 실시간 ITS 데이터를 적용할 수 있도록 지표를 재정립하였다. 요인분석을 통해 지표 간 관계성을 분석하여 가중치를 도출한 뒤 하나의 통합지표를 개발하였다. 통합지표는 교통상황의 변화와 안전도의 변화를 보여줄 수 있는 지표로 향후 교통정보센터에 적용하여 종합 적인 교통상황을 모니터링할 수 있는 교통환경으로의 발전에 기여할 수 있을 것이다.

In traffic management, gaps in understanding traffic conditions continue to exist. While the self-belonging problem indicator develops relative to speed, belonging, and self-based relative inclination, it does not apply elimination criteria that may indicate situations that contrast with attribute-specific problems. In this study, we develop integrated indicators that specify communication situations and safety levels for modeling. We review indicators of changes in traffic conditions and raise safety issues, reviewing the indicators so that ITS data can be applied, analyzing the relationships between indicators through factor analysis. We develop combined, integrated indicators that can show changes and stability in traffic situations and that can be applied in traffic information centers to contribute to the development of a traffic environment that can monitor related traffic conditions.

[연구목적] 본 연구는 초등학생 행위주체성의 개념 및 구성 요인을 밝히고 이를 측정하기 위한 도구를 개발하여, 초등학생 행위주체성 개념의 의미를 공유하고 실천적으로 논의하 는 것을 목적으로 시행하였다. [연구방법] 이러한 목적을 달성하기 위해 문헌 연구를 바탕으로 문항을 구안하였으며, 구안한 문항에 대한 전문가 검토로 내용타당도를 검증하였고, 탐색적 요인분석과 확인적 요인분석으로 구인타당도를 검증하였다. 마지막으로 준거 도구와의 상관관계를 확 인하여 공인타당도를 검증하였다. [연구결과] 초등학생 행위주체성은 ‘긍정적 자기 신념’, ‘도덕적 책임 의식’, ‘협력적 참여’, ‘자 기 결정적 학습’, ‘목표지향 행동’, ‘자기 인식’, ‘실천적 확산’의 7개 요인, 32개 문 항으로 이루어진 개념이었으며, 이를 측정하는 도구는 본 연구를 통해 타당성을 입 증하였다. [결 론] 초등학생 행위주체성은 7개 요인이 총체적으로 상호작용하며 구성하는 개념이다. 또한 초등학생은 학생 내부의 자아, 개인 및 공동체의 생활과 학습의 영역에서 자 기 자신, 동료, 교사와 상호작용하며 행위주체성을 발휘한다는 사실을 알 수 있다.

Purpose: This study was conducted for the purpose of sharing and practically discussing the meaning of the concept of agency in elementary school by identifying the concept and constructs of student agency in elementary school and developing inventory to measure it. Methods: For this purpose, the questions were devised through literature research, the content validity was verified through expert review of the devised questions, and the construct validity was verified through exploratory factor analysis and confirmatory factor analysis. Finally, the concurrent validity was verified by confirming the correlation with the reference inventory. Results: Agency of elementary school students was a concept consisting of 7 constructs and 32 items. The seven factors were 'positive self-belief', 'sense of moral responsibility', 'cooperative participation', 'self-determined learning', 'goal-oriented behavior', 'self-awareness', and 'practical expansion'. And the inventory for measuring this was verified through this study. Conclusion: Agency of elementary school students is a concept composed of seven factors interacting and constructing as a whole. In addition, it was found that elementary school students interact with themselves, colleagues, and teachers in the areas of life and learning within students.
