Purpose: This study focuses on developing a structural equation model of variables influencing loyalty to buying and selling food products through e-marketplaces in Thailand. The variables investigated comprised food attributes, online system attributes, marketing innovations, attitudes, and satisfaction. Research design, data and methodology: An online questionnaire was used to collect data from a sample group (200 buyers and 200 sellers) using quota sampling. The data were analyzed using the structural equation model. Results: The developed structural equation model was consistent with the empirical data. Factors in the model could explain 40.1% of the variance in loyalty to buying and selling food products through e-marketplaces. Food attributes and online system attributes influenced satisfaction directly. Online system attributes, market innovation, and attitudes directly influenced loyalty. The developed model had no variation between groups of buyers and sellers. Conclusions: This research demonstrated the causal factors leading to consumer loyalty to buying and selling food products through e-marketplaces. The research findings help e-marketplace providers manage factors of buying and selling to comply with the needs of buyers and sellers, which will increase the number of buyers and sellers, help generate long-term profits for service providers, and increase the country's financial value.

본 튜토리얼은 PLS 경로분석 수행을 지원하는 R 패키지인 "plspm"을 이용하여 구조방정식모형을 분석하는 방법을 제시하고 있다. 본 튜토리얼에서는 이를 위해 기존 연구들에서 제시하고 있는 PLS구조방정식모형을 분석하기 위한 기준들을 정의하고, 하나의 예시 연구모형을 제시하여 실질적으로 R을 이용하여 이 예시 모형을 분석하는 것을 보여준다. 본 튜토리얼은 PLS를 처음 접하는 연구자들에게는 연구모형에 대한 실증분석을 위한 유용한 가이드가 될 것이며, 이미 PLS에 익숙한 연구자들에게는 R을 이용한 새로운 PLS 구조방정식모형 분석기법 제시를 통하여 R이라는 통합된 통계 소프트웨어 운영환경에서 심도 있는 분석을 위한 기반 지식을 제공할 것이다.

Purpose: This study was designed to construct and test a structural equation model on sexual function in women with gynecologic cancer. Methods: The model was constructed and tested under the hypotheses that women's physical changes in sexual function after gynecologic cancer treatment did not automatically lead to sexual dysfunctions. Women's psychosocial factors were considered to be mediating variables. Two hundred twelve women with cervical, ovarian, and endometrial cancer were recruited and asked to complete a survey on their physical factors, psychosocial factors and sexual function. Data was analyzed using SPSS WIN 12.0 and Amos WIN 5.0. Results: Predictors of sexual function in the final model were sexual attitude affected by physical distress and couple's age, sexual information affected by physical distress and couple's age, depression affected by physical distress, and marital intimacy affected by physical distress. Tumor stage and time since last treatment directly affected women's sexual function without any mediating psychosocial variables. However, body image did not affect women's sexual function. Conclusion: Nursing professionals should develop a tailored educational program integrating both physical and psychosocial aspects, and apply it to women and their spouses in order to promote sexual function in women with gynecologic cancer.

Purpose: This study was designed to construct and test a structural equation model for life satisfaction in grandmothers who were parenting grandchildren Methods: Grandmothers assuming part-time parenting responsibilities for grandchildren were recruited in four cities in South Korea. They were asked to complete a questionnaire through face to face interviews or self reports, and 248 data units were analyzed with Structural Equation Modeling. Results: Model fit indices for the final model revealed a fit at an excellent level, and all of the 12 paths were statistically significant explaining 51% of the variance. Predictors of life satisfaction in the final model were parenting efficacy, perceived health status, parenting stress, amount of parenting, and demographic factors. The new findings of this study were as follows: First, the satisfaction with life of part-time parenting grandmothers was less than that of non-parenting grandmothers. Second, parenting stress and parenting efficacy revealed determinants to life satisfaction. Third, motivation of parenting and amount of parenting affect both parenting stress and parenting efficacy. Conclusion: The value of parenting and the grandmother-adult children relationship quality should also be considered in developing a grandmothers' educational program, because these are the factors which strengthen parenting efficacy and alleviate parenting stress.

본 연구는 간호대학생의 자기조절학습에 영향을 주는 요인들의 구조 방정식 모형을 만들고 검증하기 위함이다. 이를 위해 재학 중인 간호대학생들에게 자가보고식 설문지를 작성하게 하여 273부의 자료를 구조방정식 모형으로 분석하였다. 분석결과 모형 적합지수는 적절한 수준을 나타내었고, 6개 경로 중 5개 경로는 통계적으로 유의미하여 분산의 68%를 설명하였다. 따라서 간호대학생의 자기조절학습을 증진시킬 수 있도록 자기결정동기, 대인관계유능, 성취목표지향을 향상시키는 교육이 필요하며, 이를 위해 간호대학생의 자율성과 관계성을 증진시킬 역량 강화 프로그램이 개발되어야 할 것이다.

최근 4차 산업으로의 산업 패러다임의 변화가 이미 시작되었으며, 이러한 4차 산업 시대에 무형 지식재산인 특허의 중요성은 날로 증대되고 있다. 특허의 기술가치평가는 전문가의 의견에 따라서 산정되기 때문에 많은 비용과 시간이 소모되므로 비전문가들의 주관적인 의견에 기인하여 특허의 질적 수준을 판단하게 된다. 따라서 특허의 질적 수준에 대한 객관적이고 합리적인 평가 체계 개발이 필요하다. 본 논문에서는 특허의 가치평가를 기술성, 권리성, 활용성으로 구분하고 베이지안 구조방정식을 사용하여 특허의 정량화되고 객관적인 평가 모델링에 대해 고려하였다. 특히, 한국발명진흥회에서 수집한 자료를 토대로, 직접적으로 측정되기 어려운 질적 성과들을 모형화하고 평가하는데 탁월한 구조방정식과 사전 정보를 활용함으로써 작은 표본 하에서도 안정적인 모형화가 가능한 베이지안 접근법을 함께 적용하여 특허 평가 모형을 개발하였다.

Purpose: This study is aimed to introduce the application of phantom approach with structural equation modelling method for online learning. By integrating these innovative methodologies, the research seeks to advance the understanding of how the phantom approach can effectively complement and augment structural equation modeling techniques. Research design, data and methodology: A theoretical framework of Technology Acceptance Model (TAM) was modified and updated. A questionnaire was developed and used to extract information from 189 instructors who used online learning as their primary medium. The Covariance Based Structural Equation Modelling (CBSEM) was applied to test the direct effects and the phantom approach is used to handle the 2 mediators in the model. Results:social influence, perceived usefulness, and perceived ease of use exerted discernible impacts on instructors' intentionsto engage in online learning. These findings illuminate the intricate dynamics influencing instructor behavior within the realm of online education, underscoring the significance of various factors in shaping their intentions. Conclusions: In additions, the perceived usefulness and perceived ease of use had mediated the effect of social influence and instructor intention using phantom approach. Therefore, one can have concluded that this modified model was also confirmed, thereby reinforcing distribution strategies to online learning and overall education presence.

청보리는 국내에서 자급자족되는 중요한 동계 풀사료이다. 본 연구는 구조방정식 모형을 이용하여 온도, 강수 및 일조시간과 관련 있는 기후요인이 청보리의 생산량에 미치는 경로와 영향력을 파악하였다. 청보리의 소표본 자료의 한계를 보완하기 위하여 베이지안 구조방정식 방법을 사용하였다. 베이지안 방법의 사전분포로 표준정규분포, 청보리 자료의 빈도론적 구조방정식 결과와 가장 대중적인 동계 풀사료인 이탈리안 라이그라스의 빈도론적 구조방정식 결과를 이용하였다. 또한, 사전분포의 헤이우드 케이스 수정을 하지 않은 경우와 수정한 경우에 대하여 구한 사후분포의 결과를 비교하여 동계작물의 생육특성과 잘 부합하는 사전분포를 탐색하였다. 분석 결과, 사전분포의 헤이우드 케이스를 수정하여 이탈리안 라이그라스의 빈도론적 구조방정식 결과를 사전분포로 사용하는 것이 가장 적절하였다. 그러므로 본 연구의 베이지안 접근법을 통해 표본 수집이 어려운 풀사료 연구에 좋은 제안이 될 것이다.

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.
