본 연구는 노인의 주관적 건강, 근로능력, 경제활동 참여, 삶의 만족 간 구조적 관계를 분석하는 데 목적이 있다. 최근 각 사회에서는 생산적 노화, 적극적 노년 등의 관점을 통해 노인에 대한 사회적 부담을 경감시키고 부정적 인식을 완화시키기 위해 노력해 왔으며, 특히 삶의 질을 향상시키기 위한 건강과 참여에 주목하고 있다. 본 연구의 분석 대상은 한국복지패널 10차 데이터(2015년)에서 65세 이상인 노인 3,392명을 대상으로 하였다. 분석 결과, 노인의 건강과 근로능력, 경제활동 참여는 삶의 만족에 직접적인 영향을 미치는 것으로 나타났다. 둘째, 노인의 건강은 근로능력과 경제활동 참여에 유의한 영향을 미쳤다. 셋째, 근로능력은 경제활동 참여에 정적으로 유의한 영향을 미쳤다. 분석결과를 바탕으로, 노인의 삶의 만족을 향상시키기 위한 주요 요인으로써 건강과 근로 관련 요인들에 대해 중요하게 고려할 것을 제언하였다.

본 연구는 장애인들의 취업의사에 영향을 미치는 주요 요인으로서 가족의 긍정적 의사표현, 사회적 관계망, 그리고 장애정체감의 경로를 분석하는 데에 목적이 있다. 이를 위해 2010년 전국가정폭력 실태조사 자료 중 장애인관련 시설을 이용하는 성인장애인 453명을 대상으로 수집된 자료를 바탕으로 구조방정식 모형을 사용하여 주요 변수들의 인과관계를 검증하였다. 연구결과에 의하면, 가족원의 장애인에 대해 긍정적 의사표현의 빈도가 높을수록 장애인의 장애정체감과 취업의사가 증가되었다. 또한 사회적 관계의 빈도가 높을수록 장애인의 장애정체감이 상승되었으나 취업의사에는 직접적으로 영향을 미치지 않는 것으로 나타났다. 마지막으로 장애정체감은 취업의사를 결정하는 주요 요인으로서 파악되었다. 이상의 연구결과를 바탕으로 장애인의 낮은 취업의사로 인한 사회통합의 문제를 완화하고 예방하기 위한 개입 방안을 제언하였다.

This paper presents an approach to derive probability models for use in structural reliability studies. Two main points are made. First, that it is possible to translate engineering and physics knowledge into a requirement on the form of a probability model. And second, that making assumptions about a probability model for structural failure implies either explicit or hidden assumptions about material and structural properties. The work is foundational in nature, but is developed with explicit examples taken from planar and general stress problems, the von Mises failure criterion, and a modified Weibull distribution.

For large structural eigen-analysis, the whole structure is divided into some partitioned structures and through synthesis of partitioned structural model the eigen-data of structure can be obtained. In that case, eigenvalue problem consists of semidefinite mass matrix form because of displacement constraint condition. In this work the eigenvalue problem is considered by means of several method, determinant search and null space reduction method.

A large prropotion of structural failures are due to human error at the design stage of a structural engineering project, and many of these failures could have been prevented if there had been proper design checking. Analyses of the data from the 6 engineering firms and 24 professional engineer practitioners are shown on diagrams, also applicated for suggested models; overview checking. And then analyzed results of current work in this area, which examine the effects of error magnitude, are compared to the limit data obtained from the surveys. Overview checking only is analyzed of three typical design checking processes; self checking; Independent detailed checking, and overview checking.

This paper is concerned with development of the production-oriented structural design information system to predict the inaccuracy level of panel blocks and to consider the result at the structural design stage. Emphasis is placed on that the inaccuracy during production should likely be considered at the structural design stage to reduce the undesirable adjusting work and therefore to enhance the productivity. The primary goal of the present study is to consider the productivity and the efficient design at the same time for a high quality product of panel block. Usefulness of the developed information are illustrated through some application examples.

Generally seismic isolation is achieved by supporting the structure on laminated rubber bearings, friction pendulum bearings, roller bearings etc. Very little work has been performed using soil as a base isolation media. Experiments and analytical work has been performed on a structural model with isolated footing and found encouraging results. Details of this work are presented in this paper.

The purpose of this study is to identify elements of job crafting impacts on work engagement and individual work performance in Vietnamese commercial banks. The research data, collected from 226 bank officers, uses the quantitative research tools as: Cronbach's Alpha Analysis, Explanatory Factor Analysis, Confirmatory Factor Analysis as well as Structural Equation Modeling. The results of the hypothesis test show that only two hypotheses (H2, H3) are accepted: the impact of cognitive crafting on work engagement of bank officers (H2) and the impact of work engagement on individual work performance (H3). However, three remaining relationships (H1, H4, H5) are not accepted in the study: the impact of relational crafting on work engagement of bank officers (H1), the impact of relational crafting on individual work performance of bank officers (H4) and the impact of cognitive crafting on individual work performance of bank officers (H5). The study results indicate that cognition on job crafting leaves positive impacts on work engagement, leading to individual work performance enhancement. On the other hand, the relational crafting element implies contribution on neither collective nor individual working performances. Furthermore, no direct effect of cognition on job crafting to individual performance has been identified.

Purpose The purpose of this study is to examine the effect that insecurity and autonomy of platform work have an influence on work-life balance and psychological well-being in an era of platform economy based on two characteristics of online platform work and self-determination theory. Design/methodology/approach This study suggested the structural equation model integrating two antecedents, insecurity and autonomy, work-life balance, and psychological well-being and proposed five hypotheses driven from the research model. A total of 334 valid samples were collected from platform workers by employing questionnaire including 24 question items of four constructs. Findings Three hypotheses were supported and one hypothesis was not supported at the significance level of 0.05. Insecurity of platform work has a negative influence on work-life balance at the significance level of 0.01, whereas insecurity of platform work has no a significant influence on psychological well-being. Autonomy of platform work has a positive influence on both work-life balance and psychological well-being at the significance level of 0.01. Work-life balance has a positive impact on psychological well-being at the significance level of 0.001. Insecurity have an influence on psychological well-being indirectly through mediation of work-life balance. Implications for academicians and practitioners were suggested.

본 연구는 과수원에서 높은 곳에서의 작업을 진행함에 있어 안정적인 고소작업 기계차의 제작을 위하여 진행하였다. 과수원의 경우 비포장도로 및 경사진 지면이 많아 고소작업 기계차가 과수원에서 작업함에 있어 전복이 되거나 안전성에 관하여 문제가 되고 있는 부분을 해결하기 위함이다. 보다 안정적인 작업을 위하여 Auto leveling system을 설계 하였고 구조해석을 하는 도중 우리가 원하는 기준에 부합하지 않아 수평센서를 추가적으로 설치하였다. INVENTOR를 바탕으로 3D 모델링을 통해 구조해석을 한 결과 작업자가 작업할 수 있는 최대 기울어짐 정도는 좌측 116.49Mpa, 우측 118.26Mpa로 나타났다.
