Objectives To explore the path through which depression contribute to the decrease in psychological well-being, this study examined the validity of a path model that depression leads to psychological well-being through experiential avoidance, nonacceptance of positive emotion, prioritizing of positivity. Methods Depression, avoidance of experience, nonacceptance of positive emotions, prioritizing of positivity, and psychological well-being were measured for 366 undergraduate students. The correlation between variables was analyzed. After item parcel, model fit and significance of paths between latent variables were analyzed using structural equation modeling. Results First, there was no significant correlation between experiential avoidance and prioritizing of positivity, but there were significant correlations between depression, experiential avoidance, nonacceptance of positive emotion, prioritizing of positivity, and psychological well-being. Second, the indirect pathways from depression to experiential avoidance, nonacceptance of positive emotion, prioritizing of positivity, and psychological well-being were found to be significant. Conclusions These results suggest that acceptance of positive emotions and pursuit of positive experiences are necessary to prevent a decrease in psychological well-being due to depression. Finally, the implications and suggestions of this study are discussed. 목적 본 연구는 우울이 심리적 안녕감의 저하에 기여하는 경로를 탐색하기 위하여 선행연구를 기반으로 우울이 경험회피, 긍정정서비수용, 긍정성 추구를 통해 심리적 안녕감으로 이어지는 경로 모형을 설정하여 타당성을 검증하였다. 방법 이를 위하여 대학생 366명을 대상으로, 우울, 경험회피, 긍정정서 비수용, 긍정성 추구, 심리적 안녕감을 측정하였다. 변인간상관관계를 분석하였고, 문항 합산을 통해 변인별 관측변인을 생성한 뒤 구조방정식 모델링을 통해 모형 적합도, 잠재변인간 직접경로 계수의 유의성, 그리고 간접경로의 유의성을 분석하였다. 결과 첫째, 경험회피와 긍정성 추구는 유의한 관련이 없었으나, 이를 제외한 우울, 경험회피, 긍정정서 비수용, 긍정성 추구, 심리적안녕감 간의 유의한 상관관계가 나타났다. 둘째, 우울에서 경험회피, 긍정정서 비수용, 긍정성 추구, 심리적 안녕감에 이르는 직접경로가 유의하였고, 경험회피와 긍정성 추구, 긍정정서 비수용과 심리적 안녕감의 직접경로는 유의하지 않다. 셋째, 우울에서 경험회피, 긍정정서 비수용, 긍정성 추구, 심리적 안녕감에 이르는 간접경로가 유의하게 나타났다. 결론 이러한 결과는 우울로 인한 심리적 안녕감 저하를 예방하기 위해서 긍정정서에 대한 수용과 긍정적 경험의 추구가 필요함을시사한다. 끝으로 본 연구의 함의와 제언을 논의하였다.

The objective of this study was to investigate non-point sources (NPS) pollution and prioritize management areas affected by NPS pollution in the Saemangeum Watershed. AHP (Analytical Hierarchy Process) technique was selected to prioritize sub-watersheds for effectively managing NPS pollution in this study areas. Generation properties of NPS pollution, discharge properties of NPS pollution, and runoff properties of NPS pollution were selected and set for AHP. Weighted descriptors including indicators like numbers of livestock, land- and livestock-system loads, rainfall, and impervious area ratio were generalized from 0 to 1 and multiply each index based on screened 17 survey data. The results were visualized as maps which enable resource managers to identify sub-watersheds for effective improving water quality. The sub-watersheds located in Gongdeok-Myeon, Yongji-Myeon, Hwangsan-Myeon of Gimje-Si were selected for managing NPS pollution control areas. This result presented that these sub-watershed are more affected by the pollution from livestock-system than from land-system. The finding from this study can be used to screen sub-watersheds that need further assessment by managers and decision-makers within the study area.

휠체어 이용자의 도시철도역사 이용편의성 향상을 위한 정책 우선순위 분석: 비대칭 영향-성과 분석을 활용하여

황진욱 대한교통학회 2023 대한교통학회지 Vol.41 No.6

교통약자의 이동권은 우리나라 법에 명시된 기본적인 권리이다. 그러나 실상은 교통약자의 이동권이 보장되지 못하여 일상생활과 사회참여에 부당한 제약을 겪는 경우가 많다. 교통약자 중에서도 장애인은 개인의 신체적·정신적 조건의 특수성으로 인해 비장애인의 경우와는 다른 정책 대안을 고려하여 이동권을 보장하는 노력이 필요하다. 특히, 휠체어 이용자는 이동하기 위해 반드시 휠체어라는 이동 보조 장치를 사용해야 하므로 더욱 세밀한 대안 마련이 필요하다. 이에 본 연구는 휠체어 이용자의 이동권 보장을 위해 주요 대중교통수단 중 하나인 도서철도 서비스의 이용편의성 향상을 위한 개선사항을 도출하고 그 우선순위를 결정하는 데 근거로 활용할 수 있는 자료를 제공하고자 한다. 이를 위해 본 논문에서는 부산 지역의 도시철도역 이용편의성 평가를 중심으로 연구를 수행하였다. 연구를 위해 휠체어 이용자를 대상으로 설문조사를 수행하였고, 수집된 자료를 바탕으로 비대칭 영향-성과 분석(asymmetric impact-performance analysis)을 사용하여 도시철도역의 이용편의성 제고를 위한 개선사항 및 우선순위를 도출하였다. 비대칭 영향-성과 분석은 전통적으로 사용된 중요도-만족도 분석(importance-performance analysis) 기법을 이론적·방법론적으로 개선한 분석기법으로 분석결과에 대한 신뢰성을 높였다고 할 수 있다. 본 연구의 분석결과에 따르면 휠체어 이용자의 도시철도역 이용편의성 향상을 위해 가장 시급한 과제는 역에 설치된 엘리베이터의 개선이며, 휠체어 리프트, 승강장의 접근성, 안내표지 및 역무원 서비스 순으로 개선의 우선순위를 정할 수 있었다. The right of mobility is a fundamental entitlement protected by Korean law for individuals facing transportation disadvantages. However, practical implementation often falls short, resulting in unjust constraints on daily life and societal engagement. Among those with transportation disadvantages, dedicated efforts are crucial to secure the rights of individuals with disabilities, considering their physical and/or mental conditions. Wheelchair users, in particular, require tailored solutions due to their reliance on mobility aids. This study seeks to furnish evidence for establishing priorities and enhancements to improve the accessibility of urban railway services, a key mode of public transportation for people with disabilities. To achieve this, the research focused on evaluating the convenience of using urban railway stations in Busan, Korea, through a survey targeting wheelchair users. Employing asymmetric impact-performance analysis, a theoretical and methodological enhancement over traditional importance-performance analysis, the study aimed to derive reliable results. The findings underscore the pressing need to enhance station elevators as the foremost priority for improving the convenience of urban railway stations for wheelchair users. Additionally, suggested areas for improvement, in order of priority, include wheelchair lifts, platform accessibility, and information signage and service staff assistance.

Developing Build-Own (or Operate)-Transfer (BOT) nuclear power project carrying large capital in the long term requires initially well-made multi-decision which it prevents sorts of risks from unexpected situation of target countries. In order to analyze the feasibility of project country, the Analytic Hierarchy Process is adopted. Firstly, the factors influencing the success of BOT nuclear power project in overseas countries were investigated through the literature survey for the country risk and were evaluated by expert interview for estimating comparative weight through pairwise comparison between such factors. Finally, it is developed comparative database of alternate countries with respect to each factor. This analytic method enables the developer to select and focus on the country which has preferable circumstance so that it enhances the efficiency of the project promotion. Also, it enables the developer to quantify the qualitative factors so that it diversifies the project success strategy and policy for the target country.

장종화,이상엽 한국자치행정학회 2012 한국자치행정학보 Vol.26 No.1

드림스타트사업의 지역 간 욕구차이를 감안하여 농촌지역 드림스타트사업 프로그램의 우선순위를 결정하기위해 관련 전문가 35명을 대상으로 설문조사를 실시하였다. AHP 분석을 이용하여 프로그램의 상대적 중요도를 도출한 결과, 보건복지부 드림스타트센타에서 제시하는 프로그램 중 농촌지역에서 가장 우선적으로 필요한 서비스 프로그램 50개는 정서/행동 부문(21개), 신체/행동 부문(20개), 인지/언어(9개)로 분석되었다. 드림스타트사업 프로그램의 측정영역별 상대적 중요도는 정서/행동 부문(0.349), 신체/건강 부문(0.317), 인지/언어 부문(0.265), 기타 부문(0.068)의 순이었다. 신체/건강 부문에 대한 중요도 인식은 프로그램별 차이가 많았으며, 부모교육, 정신건강, 건강검진 및 예방의 순으로 높고 치료지원 영역이 가장 낮았다. 인지/언어 부문의 중요도 인식은 다소 낮게 분석되었지만, 기초학습 영역 프로그램인 한글깨치기, 쉽게 쓰는 일기는 높은 수준으로 나타났다. 반면 정서/행동 부문에서는 전반적으로 중요도 인식이 높았으며, 특히 기본생활습관교실과 사회성향상프로그램, 분노조절프로그램, 성폭력예방 등의 프로그램이 높은 수준으로 나타났다.

Integration of Heuristic and Statistical Methods for Estimation of Cyclist Injury Severity

주신혜,정소영,오철 대한토목학회 2017 KSCE JOURNAL OF CIVIL ENGINEERING Vol.21 No.1

The number of crashes that involve bicycles and result in severe injuries has increased every year in the Republic of Korea, though bicycling is a promising alternative transportation mode that can help address transportation emission problems. Correspondingly, this study intends to quantitatively examine the impacts of contributing factors on the cyclist injury severity levels and to provide meaningful insight into prioritizing and specifying strategies for improving cyclist safety. To this end, a decision tree and ordered probit regression were integrated in this study. The findings showed that heavy vehicle use and cyclist age should be preferentially considered when implementing cyclist safety improvement strategies: targeting young heavy-vehicle drivers or cyclists, driver education regarding proper curve maneuvering and a law enforcement prohibition of speeding are suggested, and ITS-based traffic management system and road facilities would help enhance light vehicle driver visibility and senior cyclist alertness, particularly in horizontally curving road sections. These data-driven results could quantitatively support the policy makers or practitioners making decisions about prioritizing cyclist safety improvement strategy implementations and further specifying such strategies.
