Purpose: As the importance of software has been emphasized recently, the size of the software market is continuously expanding. The development of the software market is being adversely affected by software piracy. In this study, we try to classify countries around the world based on the macro environmental factors, which influence software piracy. We also try to identify the differences in software piracy for each classified type. Design/methodology/approach: The data-driven approach is used in this study. From the BSA, the World Bank, and the OECD, we collect data from 1990 to 2015 for 127 environmental variables of 225 countries. Cronbach's ${\alpha}$ analysis, item-to-total correlation analysis, and exploratory factor analysis derive 15 constructs from the data. We apply two-step approach to cluster analysis. The number of clusters is determined to be 5 by hierarchical cluster analysis at the first step, and the countries are classified by the K-means clustering at the second step. We conduct ANOVA and MANOVA in order to verify the differences of the environmental factors and software piracy among derived clusters. Findings: The five clusters are identified as underdeveloped countries, developing countries, developed countries, world powers, and developing country with large market. There are statistically significant differences in the environmental factors among the clusters. In addition, there are statistically significant differences in software piracy rate, pirated value, and legal software sales among the clusters.

Objectives The Beck Depression Inventory (BDI) is one of the most widely used self-report measures of depression in both research and clinical practice. The Beck Depression Inventory Second Edition (BDI-II) is the most recent version of the BDI. Validity of the BDI-II has been documented in other countries. This study examined the factor structure of the Korean version of BDI-II in a large sample of university students. Method Data were obtained from 2,529 students of Kongju National University. The factor structures of the Korean version of BDI-II were assessed using exploratory and confirmatory factor analysis. Results A high level of internal consistency and reliability (Cronbach's ${\alpha}$ = 0.91) and item homogeneity was confirmed. Exploratory factor analysis showed a two-factor structure (cognitive and somatic-affective), which was almost identical to the original model demonstrated by Beck et al. The following confirmatory factor analysis also supported the two-factor structure (cognitive and somatic-affective) is a better fit than the other two-factor structure (cognitive-affective and somatic). The higher mean score for women compared to men is consistent with the results of previous reports. Conclusion These data support the reliability and concurrent validity of the Korean version of BDI-II as a measure of depressive symptoms in nonclinical samples.

Background: Given that there are many Iranian women who have never had a Pap smear, this study was designed to develop and validate a measurement tool based on the Protection Motivation Theory to assess factors influencing the Iranian women's intention to perform first Pap testing. Materials and Methods: In this psychometric research, to determine the Content Validity Index (CVI) and the Content Validity Ratio (CVR), a panel of experts (n=10) reviewed scale items. Reliability was estimated through the Intraclass Correlation Coefficient (n=30) and internal consistency (n=240). Also, factor analysis (exploratory and conformity) was performed on the data of the sample women who had never had a Pap smear test (n=240). Results: A 26-item questionnaire was developed. The CVI and CVR scores of the scale were 0.89 and 0.90, respectively. Exploratory factor analysis loaded a 26-item with seven factors questionnaire (perceived vulnerability and severity, fear, response costs, response efficacy, self-efficacy, and protection motivation (or intention)) that jointly accounted for 72.76% of the observed variance. Confirmatory factor analysis indicated a good fit for the data. Internal consistency (range 0.70-0.93) and test-retest reliability (range 0.72-0.96) of sub-scales were acceptable. Conclusions: This study showed that the designed instrument was a valid and reliable tool for measuring the factors influencing the women's intention to perform their first Pap testing.

This study analyzes the type of preferred shopping items based on tourism shopping value pursued by tourists through shopping at travel destinations as well as verifies their impact on satisfaction. A survey on 310 adult men and women aged 20 to 69 collected data samples representing tourism shoppers in Korea. Based on the collected data, a factor analysis and a structural model equation analysis were performed using SPSS 25.0 and AMOS. Tourism shopping value was divided into functional value, emotional value, exploratory value, and shared value. In addition, shopping items were categorized as physical materials and experience materials to identify the difference in preferred item types according to the value that tourists perceive. It also confirmed the adjustment effect of tourism motivation that affects tourism shopping behavior. According to the analysis results, the more tourists perceive functional and emotional values when shopping, the more physical material they prefer, and the more they perceive exploratory values, the higher the preference for experience goods. However, the shared value affected both physical materials and experience materials. Based on escape-seeking motivation, the adjustment effect of tourism motivation (a major variable to understand the behavior of tourists) on tourism shopping behavior was confirmed. Based on the academic and practical implications of this study, we hope to broaden our understanding of tourism shopping and revitalize research on tourism shopping.

Purpose: This study aimed to translate the Infertility Stigma Scale (ISS) into Korean and to evaluate its reliability and validity in the Korean context. Methods: Data were collected from 350 women who underwent in vitro fertilization (IVF). Data were analyzed using SPSS WIN 25.0 and AMOS 22.0. Content validity was analyzed using the item-level content validity index (I-CVI) and scale-level content validity index/averaging (S-CVI/Ave). The preliminary survey was conducted on 20 women who had experienced IVF at least once to check the level of understanding of the tool and the time required to fill out the questionnaire. Exploratory and confirmatory factor analyses were used to test construct validity. Additionally, hypothesis-testing construct validity were tested. Cronbach's α was used to assess the reliability. Results: The Korean-ISS (K-ISS) consists of 25 items, excluding two items from the original ISS questionnaire. Exploratory factor analysis identified four factors, which explained 75.6% of the total variance. The four distinct factors were infertility stigma with self-devaluation (56.8%), public stigma (8.1%), social withdrawal (6.5%), and family stigma (4.2%). In the confirmatory factor analysis, the 25 items in the four-factor structure were validated (χ² /df ≤ 3, RMSEA ≤ 10). The hypothesis-testing construct validity of K-ISS against FPI (r = .58~.71, p < .001) and FQI (r = - .49~- .65, p < .001) was tested and found to be significant. The internal consistency reliability of the K-ISS, assessed using Cronbach's α, was .97. Conclusion: The K-ISS has satisfactory construct validity and reliability; therefore, it can help minimize the negative impact of stigma by measuring the stigma associated with women experiencing infertility.

In recommender systems which are used widely at e-commerce, collaborative filtering needs the information of user-ratings and neighbor user-ratings. These are an important value for recommendation in recommender systems. We investigate the in-formation of rating in NBCFA (neighbor Based Collaborative Filtering Algorithm), we suggest new algorithm that improve prediction accuracy of recommender system. After we analyze relations between two variable and Error Value (EV), we suggest new algorithm and apply it to fitted line. This fitted line uses Least Squares Method (LSM) in Exploratory Data Analysis (EDA). To compute the prediction value of new algorithm, the fitted line is applied to experimental data with fitted function. In order to confirm prediction accuracy of new algorithm, we applied new algorithm to increased sparsity data and total data. As a result of study, the prediction accuracy of recommender system in the new algorithm was more improved than current algorithm.
