In this paper, we validate MEDIQUAL constructs through different media users in help desk. In a previous paper only two end-users' constructs were used: assurance and responsiveness. In this paper we extended MEDIQUAL constructs to include reliability, empathy, assurance, tangibles, and responsiveness, which are based on the SERVQUAL theory. The results suggested that: 1) five MEDIQUAL constructs were validated through the factor analysis. That is, importance of the constructs have relatively high correlations between measures of the same construct using different methods and low correlations between measures of construct that are expected to differ (Cronbach, 1971; Campbell and Fiske, 1959) 2) five MEDIQUAL constructs are statistically significant on media users' satisfaction in help desk service by regression analysis.

Recently, traceability systems are introduced as a new food safety information system. To trace food products efficiently, they must have an automatic identification capability at the individual product level. This capability can be gained through RFID technology. But there is not yet any performance evaluation tool on RFID-based traceability systems (RFID-TS). This study developed an evaluation tool of RFID-TS. To develop the tool, this study considered the objective and the components of RFID-TS as their performance constructs. According to Churchill's paradigm, the tool was established through two stages. The final evaluation tool consisted of four constructs (risk, operational benefits, IS (information system), and network) and nine sub-constructs. Among the four constructs, risk and IS were found as the most important performance constructs through regression analysis. Among the nine sub-constructs, service (which belonged to the IS construct) and economic risk (which belonged to the risk construct) were found as the most important performance sub-constructs.

It has been suggested that children's reasons for reading are various; reading efficacy, challenge, curiosity, involvement, importance, recognition, competition, compliance, grades, avoidance and social interactions. To extend previous studies in which only one or two motivational constructs were studied in relation to reading abilities, this study was carried out to examine 11 inter-relationships of motivational constructs and their relationships to reading abilities. Using the MRQ of Wigfield & Guthrie(1997), and the Basic Learning Skills Test of the Korea Educational Development Institute(1989), 334 elementary school children were measured for their reading motivation and abilities. The results showed that 11 motivational constructs were interrelated, which were also related with reading abilities. Out of 11 motivational constructs, importance was able to predict the reading abilities in multiple-regression analyses. From F-tests, those groups with high reading efficacy, challenge, curiosity, involvement, recognition, competition and social interactions outperformed those with low motivational constructs. The findings of this study confirm that children read for various reasons, and internal motivation and social interactions are significantly related with reading abilities. It is proposed that the internal reasons for reading are also more significant factors in explaining reading abilities than external reasons. Finally, cultural influences on reading motivation and comprehension are also discussed.

지난 10년간 이루어진 국제비교연구들에 따르면 우리나라 학생들은 높은 수학 학업 성취도에 비해 정의적 요인과 교사특성에 대한 지각에서 부정적인 결과를 보이고 있다. 이런 일반적인 결과에 더해, 본 연구는 TIMSS 2015 결과를 바탕으로 우리나라 학생들의 정의적 특성 및 교사 특성에 대한 지각에 대해 추가적인 정보를 제공하고자 한다. 본 연구에서는 잠재 프로파일 분석을 사용하여 학생들의 정의적 요인 및 교사특성에 대한 지각과 관련하여 질적으로 다른 다섯 그룹들을 발견하였다. 그 중에서 정의적 요인들에 비해 교사특성에 대한 지각에서 상대적으로 더 부정적인 결과를 보이는 두 그룹에 좀 더 주목할 필요가 있다. 각 그룹의 서로 다른 특징은 그룹에 속하는 학생들의 정의적 측면 및 교사특성에 대한 지각을 향상시키기 위해 서로 다른 접근 방법을 취할 필요가 있음을 시사한다. 이를 위해 학업 성취도뿐만 아니라, 정의적 특성 및 교사특성에 대한 지각에 영향을 미치는 요소들과 관련된 후속 연구가 필요함을 제안한다.

In the service industry brand was getting more importance in marketing and brand should be researched more. So the purpose of this study was to identify the causal relationships of 'constructs of brand evidence-brand satisfaction-feelings-brand satisfaction-customer loyalty'. In this research constructs of brand evidence were brand image, price (value for money), servicescapes, core service, employee service, and self-image congruence. This research used family restaurants settings using a sample of customers visiting and enjoying menus at family restaurant stores of Youngnam province. A total of 222 questionnaires were analyzed with SPSS/PC+12.0 and LISREL8.30. Empirical results were that firstly, price, core service and employee service affected brand satisfaction and secondly, employee service, core service, servicescape affected postive feelings and thirdly, brand evidence constructs except self-image congruence influenced negative feelings and lastly, brand satisfaction influenced customer loyalty. On the basis of these findings, family restaurant manager should pay much attention to constructs of brand evidence and use these variables to appeal to and understand target market.

Technology Acceptance Model (TAM) has been a basis model for testing technology use. Post researches of TAM have been conducted with the updating the TAM by adding new independent variables in order to increase the explanation power of the model. However, one problem is that different independent variables have to be introduced to keep the explanation power whenever applying to particular technology. This reduces the generality of the research model. Thus in order to increase the generality of the model, this study reviewed the previous researches and collected the independent variables used, and regrouped them into three basic independent constructs. New research model was designed with three basic independent constructs with four constructs selected for the mandatory IT environment and voluntary IT environment, and the structured equations analysis(AMOS) was applied to find the significant causal effect relationships between constructs in addition to the explanation power of the model. Finally, this study concluded that new TAM could be used to explain the users' adopting new technology without any adding new particular independent variables.

There is a growing global interest in food choices that could affect health. Consumer food choices are dictated by numerous factors such as attitudes, beliefs, desires and preferences stemming from psychological and physiological attributes. The present study aimed to understand consumers' internal perceptions about cream soup, cream sauce, and tomato sauce using ZMET (Zaltman's Metaphor Elicitation Technique). The 9 step ZMET interview process was conducted for a sample of 36 consumers (12 consumers for each sauce). A content analysis of the survey results was carried out. From this, 56 concepts of cream soup were derived, and 15 constructs that met with the agreement of more than one-third of the total sample consumers were extracted. These 15 constructs included 'Soft', 'Recollection', 'Familiar', 'Warm', 'Comfortable', etc. Similarly, for cream sauce, 67 concepts and 20 constructs 'Silky', 'Warm', 'Restaurant', 'Family', 'Memory', etc. were deduced. A total of 66 concepts and 20 constructs for tomato sauce 'Sourness', 'Sauce Bottle', 'Pleasant', 'Ingredient', 'Cooking', etc. were derived. The analysis of consumers' consensus maps through this study provides a deep and useful understanding of consumers and their latent needs. Also, the results of this study indicate that exploring consumers' internal perceptions is critical to understanding their healthy food choices. This can be used as basic data for formulating marketing strategies.

Background: It is important to validate scales related to cancer screening beliefs in order to better understand perceptions. The aim of this study was to test the psychometric properties of the colorectal cancer screening belief scale based on Health Belief Model (HBM) constructs. Materials and Methods: Data were collected from 600 persons referred to outpatient laboratory units in Iran through a convenience sampling procedure. In this cross-sectional study, exploratory and confirmatory factor analyses were used to examine construct validity of scale. Results: Through exploratory factor analysis, 52 items of the scale converged to five constructs of HBM with 4 items omission. Construct validity was determined by confirmatory factor analysis through which correlated model was supported. Cronbach's alpha coefficient for the whole scale was obtained as 0.78, which indicates reliability of the scale. Conclusions: The study findings showed that this scale is a valid and reliable instrument that can be used for measuring HBM constructs about colorectal cancer screening with the fecal occult blood test.
