  • Construction Performance measurement and management has been interested by construction practitioners. However, current construction project management practices are related to short-term improvement plans rather than long-term and systematic approaches based upon performance analysis. AR a result, there is a need for developing of a collaborative plan over project life cycle. Therefore, this paper reviews extensive literature and proposes the construction performance estimating model using a system dynamics. The paper proposes casual maps for planning, design, procurement, and construction phases. Each casual map includes all performance indicators and factors that impact on performance directly or indirectly. These casual maps that were developed by system thinking will enhance the understanding of the relationships among performances and factors. After further data gathering, these models can be used to estimate construction performance and eventually these will save project costs and shorten project schedule.

  • The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.

  • Personality traits in insomniac patients have been a subject of many studies. A number of these studies have used the MMPI and have demonstrated elevated scores on several clinical scales reflecting somatic concerns, somatization, depression, anxiety, worry and social alienation. And it was suggested that insomnia was due to a process of internalization of psychological distress. Another hypothesis about psychological mechanisms has focused upon worry. Excessive and uncontrollable cognitive activity seem to be a characteristic feature of many insomniacs. One author emphasized the role of the dependency need and found a characteristic pattern among insomniacs. The central feature of this pattern is frustration of dependency need. The purpose of this paper was to review possible personality variable that may be predisposing causal factors of insomnia. Several factors are suggested by many studies, but in order to explore their causal importance other experimental and longitudinal studies are needed.

  • The purpose of this study was to measure the factors influencing customers’ value perception of foodservice in tourist area’s restaurant. A total of 273 questionnaires were completed. Structural equation model was used to measure the causal effects. Results of the study demonstrated that the confirmatory factor analysis model also indicated excellent model fit. The proposed model yielded a significantly better fit to the data than the parsimonious model and extended model. In proposed model, the effects of perceived sacrifice, overall service quality and customer satisfaction on perceived value were statistically significant. The effects of perceived value on loyalty intention were statistically significant. As expected, the overall service quality had a significant effect on customer satisfaction. Moreover, the customer satisfaction played a mediating role in the relationship between overall service quality and loyalty intention.

  • 원인과 결과 간의 연결 강도에 관한 추정인 인과 추론에는 다수의 처리기제가 다른 처리 시점에 관여하며 따라서 이들 각각에 민감하게 작용하는 개인차 변인은 상이할 가능성이 크다. 특히, 조건부화와 절감 현상은 하나의 결과에 다수의 잠재원인이 존재할 경우 특정 원인과 결과 간의 인과 강도를 추정할 때 일어나는 주요현상에 해당한다. 본 연구에서는 맥락 민감도와 관련된 개인차 변인인 자기 해석을 조작하여 조건부화와 절감 현상에 어떠한 영향을 미치는가를 알아보았다. 그 결과 독립적 자기 조건과 상호의존적 자기 조건 간에는 조건부화 정도의 차이가 발견되지 않았다. 그러나 상호의존적 자기 조건이 더 높은 절감 현상을 보였으며 이는 조건부화와 절감 현상이 각기 다른 처리 기제임을 시사한다고 볼 수 있다.

  • Knowledge management(KM) is emerging as a robust management mechanism with which an organization can remain highly intelligent and competitive in a turbulent market. Organization memory(or knowledge) is at the heart of KM success. How to create organizational memory has been debated among researchers. In literature, a wide variety of methods for creating organizational memory have been proposed only to prove that its applicability is limited to decision-making problems which require shallow or non-causal knowledge type. However, organizational memory with a sense of causal knowledge is highly required in solving complicated decision-making problems in which complex dynamics exist between various factors and influence each other with cause and effect relationship among them. In this respect, we propose a new approach to creating a causal-typed organizational memory (CATOM), which has a form of causal knowledge and is represented in a matrix form, by using an inference diagram. An algorithm for CATOM creation is suggested and applied to an illustrative example. Results show that our proposed KM approach can effectively equip an organization with semi-automated CATOM creation and inference process which is deemed useful in a highly competitive business environment.

  • The purpose of this study is to establish a predictive causal model of codependency that is a main issue of family problem on the base of Triple ABC-X model which is a kind of family stress model. For the purpose of this study, we reviewed the concept and characteristics of codependency, affecting factors of codependency, and then reviewed the basic concept and logic of Triple ABC-X Model as theoretical viewpoint for the purpose of establishing a predictive causal model of codependency. We established it through examining main variables of codependency from Triple ABC-X Model. Main ingredients of the predictive causal model include boundary ambiguity, internal working model, internal and external locus of control, self-regard, social support, individual maladjustment etc. We established a predictive model of codependency basing on logic inferences among the variables. This study is expected to be used basic data to introduce some implications and for hereafter research.

  • The purpose of this study is that analyzing the causal relationship between Infra, Process and Performance of companies which are executing the Supply Chain Quality Management(SCQM) with their subcontractors and partners. Korean Standards Association(KSA) provides the Supply Chain Quality Management Model and Quality Collaboration Index for 4 years, but a few study has investigated the critical variables and their causal relationship to organizational performance. Therefore we examine the SCQM model and related index and choose the quality, human resource and risk management processes for identifying the path to organizational performance. In addition, exploratory factor analysis is conducted for figuring out the major factors among the 3 processes. Structural Equation Model are successively used for determining which characteristics of the infra and processes are the most critical variables to performance. The data was collected from KSA and composed of 52 companies and 346 their partners. The result shows that risk management process has no significant effect on the organizational performance and pre-production process collaboration.

  • 본 연구에서는 우리나라 학생들의 수학 학습 동기와 귀인에 대한 각각의 측정 도구를 개발하고 그 적용 결과를 분석하였다. 수학 학습 통기 측정 도구는 '자기조절효능감' 17문항, '과제난이도' 9문항, '수학 불안' 9문항의 총 35문항으로, 귀인 측정 도구는 성공과 실패 귀인으로 구분하여 개발하였다. 성공귀인은 '노력/능력'이 6문항, '운'이 4문항, '타인'이 3문항의 총 13개로, 실패귀인은 '노력'이 7문항, '운'이 3문항, '능력'이 3문항, '타인(외적)'이 4문항의 총 17개로 이루어졌다. 수학 학습 동기의 세 요인 간의 상관을 분석한 결과, 과제난이도와 자기조절효능감은 정적 관계 나타냈고 수학 불안은 다른 두 요인과 부적 관계를 보였다. 수학 성취가 우수한 집단은 과제난이도와 자기조절효능감이 가장 높았고 수학 불안은 가장 낮았으며 기초이하 집단이 수학 불안이 가장 높았다. 또 남학생이 여학생보다 어려운 문제에 도전적이며, 수학 학습에 대한 자신의 학습 능력과 노력의 정도에 대한 자가 판단이 긍정적이었다. 그러나 수학 불안에서는 여학생이 남학생보다 불안 수준이 높게 나타났다. 동기와 귀인의 각 구성 요인간 상관을 분석한 결과, 과제가 어려운 것을 선호하거나 자기조절효능감이 높은 학생일수록 수학 학습의 성공의 원인을 노력/능력 귀인에서 찾지만, 운의 탓으로 돌리는 경향은 낮았다. 수학 불안이 높은 학생일수록 수학 학습의 성공의 원인을 운으로 귀인시키는 경향이 강하였다.
