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.

This study investigated developmental trends and sex differences in the relation between children's self-esteem and relevant variables by proposing and testing the causal model. The 763 children who participated in the study were 3rd, 5th, and 7th grade students. Major findings were that physical appearance was the most powerful determinant of self-esteem. Students with high self-esteem were more learning oriented, used more motivational behaviors and had higher academic achievement. The findings from this analysis of the causal model revealed remarkable developmental differentiation and stability.

This paper developed measurement indices for intellectual capital of public R&D organizations and investigated causal relationships among the components. We developed 10 measurement factors and 37 indicators and confirmed the reliability of these measurements. We offered an alternative to the existing model for searching causal relationships. From our survey research, using the structural equation model, we found a new relationship. In contrast to the existing model, we found a cycling relationship among three variables: human capital causes structural capital, structural capital causes relational capital, and relational capital causes human capital.

개념과 범주는 관찰하지 못한 속성을 추론할 수 있는 기반을 제공한다. 무의미 속성을 사용한 범주기반 속성추론 연구들은 범주 및 속성의 유사성이 추론을 설명하는 핵심 요인이라는 것을 제안했다(Rips, 1975; Osherson et al., 1990). 이후 연구들은 사람들의 사전지식이 범주기반 추론에 막대한 영향을 미치며 심지어 유사성 효과가 완전히 사라지는 경우도 있음을 보고했다. 본 연구는 범주 속성들이 사전지식의 한 종류인 인과적 지식에 의해 사슬구조로 연결되었을 때의 범주기반 속성추론을 검증했으며 그 결과를 예측하는 속성추론모형을 제안했다. 참가자들은 네 개의 속성들이 사슬구조를 이루는 인과적 범주를 학습한 뒤 해당 범주의 다양한 범주 예시들의 숨겨진 속성에 대한 추론을 실시했다. 그 결과 인과적으로 직접 연결된 속성뿐만 아니라 다른 속성 노드에 의해 차폐된 속성들도 추론에 영향을 미치는 비독립성이 나타났다(인과적 마코프 조건의 위배). 인과모형이론(Sloman, 2005)에 기반한 속성추론모형을 적용하여 참가자들의 추론을 모델링한 결과 인과적 연결의 직접 효과뿐만 아니라 간접 효과 즉 인과추론의 비독립성도 예측하는 것으로 나타났다. 다만 간접적으로 연결된 속성들은 인과적 거리와 무관하게 참가자들의 추론평정에 동일하게 영향을 미쳤지만 모형은 거리가 멀어짐에 따라 추론에 미치는 영향이 작아짐을 예측했다.

This study measured the causal relationships among tourist-perceived sacrifice, service quality, service value, and behavioral intention of employee's service. A total of 224 questionnaires were completed. The equation model was used to measure the causal effect. The results demonstrated that the structural analysis result for the data was an excellent model fit. The influences of perceived value and service quality on service value were statistically significant. As expected, service quality and service value had significant effects on behavioral intention. Moreover, overall service quality played a mediating role in the relationship between perceived sacrifice and service value. Service value played a mediating role in the relationship between service quality and behavioral intention.

범주기반 속성추론에 대한 초기연구들은 전형성, 다양성, 유사성 효과 등 인간 사고에서 나타나는 다양한 현상들을 보고하였다. 이후 연구들은 이러한 추론에서 참가자들의 사전지식이 광범위한 영향을 미친다는 것을 발견하였다. 본 연구에서는 다양한 사전지식들 중 하나인 인과적 지식이 속성추론에 미치는 영향을 검증하고 이를 모델링하였다. 이를 위해 참가자들은 네 개의 속성으로 구성된 범주에서 속성들이 공통원인 혹은 공통효과 인과구조로 연결되었을 때 속성추론과제를 실시하였다. 그 결과 전형성 효과와 더불어 공통원인 구조에서 인과적 마코프 조건(causal Markov condition)에 대한 위배와 공통효과 구조에서 인과적 절감(causal discounting)이 관찰되었다. 이를 모델링하기 위해 참가자들은 표적속성이 존재하는 범주예시와 존재하지 않은 범주예시가 존재할 가능성에 대한 차이값 (즉, $p(E_{F(X)}{\mid}Cat)-p(E_{F({\sim}X)}{\mid}Cat)$에 근거하여 속성추론을 수행한다고 가정하였다. 인과모형이론(Rehder, 2003)에 기반하여 범주예시들의 확률값을 계산한 후 각 표적속성에 대한 추론에 적용하였다. 그 결과 모형은 참가자들의 데이터에서 관찰된 전형성 효과뿐만 아니라 인과적 마코프 조건에 대한 위배 및 인과적 절감을 모두 예측한다는 것이 확인되었다.

Weld defects degrade the strength and safety of astructure and are resulted from the various cases. The complexity of causal relation of weld defects requires an expert for the analysis of weld defects and the measures counter to them. An expert system has the intelligent functions such as the representation of knowledge and the inference. On this research, weld defect are systematically analysed and their causal model is developed. This information is saved to the knowledge base. The suitable inference algorithm for the diagnosis of weld defects is developed and realized with C++ programming.

Purpose The purpose of this study is to analyze causal relationship between quantity and quality for deriving ranking model of Online reviews. Thus, we propose implications for deriving the ranking model for retrieving Online reviews more effectively. Design/methodology/approach We collected Online review from Tripadvisor web sites which might be a kind of world-famous tourism web sites. We transformed the natural text reviews to quantified data which consists of quantified positive opinions, quantified negative opinions, quantified modification opinions, reviews lengths and grade scores by using opinion mining technologies in R package. We executed corelation and regression analysis about the data. Findings According to the empirical analysis result, this study confirmed that the review length influenced positive opinion, negative opinion and modification opinion. We also confirmed that negative opinion and modification opinion influenced the grade score.

Purpose: The ultimate purpose of this work is to investigate gender differences in the relationships between product quality cues and perceived values at a food select shop. Specifically, this study examines the effects of internal and external cues, which are indicators of product quality, on emotional and social values based on gender differences. Research design, data and methodology: In this study, a questionnaire technique was used to collect the data necessary to test the proposed model. 183 data were collected through this technique. PLS SEM (Partial Least Squares Structured Equation Model) was used to test the research model. Results: First, there is no gender difference between intrinsic cue and emotional value. When using male and female data, there was no significant causal relationship between intrinsic cues and emotional values. Second, we found no gender difference between intrinsic cue and social value. When analyzed with female data, there was no significant causal relationship between intrinsic cue and social value. On the other hand, in the case of men, it was found that a weak causal relationship exists. Third, this study found gender difference between extrinsic cue and emotional value. In the case of men, it was found that a weak causal relationship exists, whereas in the case of women, a strong causal relationship exists between extrinsic cue and emotional value. Fourth, we found gender difference between extrinsic cue and social value. In the case of men, there was no causal relationship, whereas in the case of women, there was a strong causal relationship between extrinsic cue and social value. Finally, we found that there are moderating roles of gender in the relationship between external cues and perceived quality. Conclusions: As a result of analysis, it is necessary to focus on extrinsic clues of product in order to increase the perceived emotional and social values of women. On the other hand, in order to improve the perceived emotional and social values of men, it is necessary to pay attention to both intrinsic and extrinsic cues of product. Therefore, it is necessary to consider what clues and values are important to core customers.

The effective supply chain management(SCM) is a matter of survival in many firms because successful supply chains will effectively coordinate their processes, focus on delivering customer value, eliminate unnecessary costs in key functional areas, and create performance measurement systems. The balanced scorecard(BSC) is widely used to measure the performance of the SCM. The BSC framework suggests that balance is obtained by adopting performance measures from four different areas. In this study, we analyzed the causal relationship of SCM performance based on BSC framework. First, we reviewed the nested causal relationships among four different perspective of the BSC, namely, business process perspective, customer perspective, financial perspective, and innovation and learning perspective. Then, we used the chi-square difference test to identify the best model to fit the causal relationship of SCM performance. Of the 800 questionnaires posted, a total of 265 questionnaires were returned after one follow-up. A total of 66 questionnaires were eliminated due to largely missing values. The major finding says alternative model 3 is dominant to other models to fit causal relationships among four different perspective of the BSC. Innovation and learning perspective positively influence on customer perspective, business process perspective, and financial perspective. Business process perspective also positively influence on customer perspective and financial perspective whereas customer perspective does not influence on financial perspective significantly.
