The objective of this study was to identify factors affecting the positive and negative responses of undergraduate students to inferiority by using a group counseling program to manage the inferiority of undergraduate students majoring in health science. This study sampled 30 undergraduate students attending the health science department of S University and divided them into a treatment group and a control group. The treatment group received an inferiority management group counseling program twice a week 120 minutes each from November 20, 2018, to January 2, 2019 eight sessions in total. The inferiority response criterion was applied before-treatment, after-treatment, and follow-up to verify the effectiveness of the program. The analysis results showed that the inferiority management group counseling program significantly decreased the negative response of undergraduate students to inferiority and significantly increased the positive response to inferiority. These results suggest that the inferiority management counseling program can lower the negative attitude and enhance the positive attitude toward the inferiority, which is caused by comparing themselves with their peers.

Purpose: This descriptive correlation study was designed to examine the relationship of inferiority to depression and psychosomatic symptoms in female adolescents. In addition, this study investigated the mediating effect of perceived entrapment in relation to inferiority and other variables. Method: Data were collected from 526 female high school students. Self-report questionnaires, which were constructed to include demographic factors, inferiority, perceived entrapment, depression and psychosomatic symptoms, were used for data collection. Results: Students with high inferiority showed significantly higher perceived entrapment, depression and psychosomatic symptoms. here were significant positive correlations among the variables. Perceived entrapment had a significant mediating effect in relation to inferiority, depression and psychosomatic symptoms. Conclusion: Further study is necessary to develop effective nursing interventions for managing inferiority and perceived entrapment in this population.

The objective of this study is to understand the effect of measurement-related investment. That is, this study aims at verifying the correlation between the measurement-related investment and inferiority rate of products by statistical analysis. The samples of this study are 376 industrial companies in Korea, and the research data was analysed on inferiority state of industrial companies with a measurement standard laboratory. The analysis was made by the elementary statistics, the correlation analysis and the regression analysis. The results are summarized as follows : First, the inferioriy rate of the industrial companies with a measurement standard laboratory was relatively lower than that of the other companies without the laboratory by statistical significance. Second, the increment on measurement-related investment had a negative correlation with the increment of inferiority rate, and the increase of measurement-related investment showed decrease of the inferiority rate by regression analysis.

Objectives: The purpose of this study was to explore the vivid and in-depth stories, of inferiority experienced in the lives of current Korean medicine doctors. Methods: In-depth interviews were conducted, with two participants. Collected research data were analyzed, using the narrative inquiry method suggested by Clandinin and Connelly. Results: Common themes found in participants' narrative were summarized, by 'comparison with others' and 'various attempts to overcome inferiority feeling'. Conclusions: This study is meaningful at three levels: personal, social, and practical. Also, it provides readers with an opportunity to reflect on the way they cope with their inferiority complex, which various people experience in different contexts.

Purpose: In this study the effects of a self-growth program on self-esteem, inferiority and peer-relationships in children using a community child center were examined. Methods: A quasi-experimental design was used. Data were collected from August 26 to October 9, 2008. To test the effects of the self-growth program, the children were divided into two groups, an experimental group (28) and a control group (25). The self-growth program was used with the children in the experimental group. Results: The self-growth program effectively increased the self-esteem scores, and the peer-relationships scores of the children, and decreased the inferiority scores. Conclusion: The results suggest that the self-growth program is a useful nursing intervention for improving self-esteem, decreasing inferiority, and positively affecting peer-relationships in these children.

The effect of a new treatment is proven through the comparison of a new treatment with placebo; however, the number of parent non-inferiority trials tends to grow proportionally to the number of active controls. In a non-inferiority trial a new treatment is approved by proof that the new treatment is not inferior to an active control; however, both additional assumptions and historical trials are needed to show (through the comparison of the new treatment with the active control in a non-inferiority trial) that the new treatment is more efficacious than a putative placebo. The two different methods of using the historical data: frequentist principle method and meta-analytic method. This paper discusses the statistical methods and different Type I error rates obtained through the different methods employed.

This study aimed to check the role of SNS upward comparison and SNS usage motivation in the effect of contingent self-esteem on inferiority feelings by verifying the link between each variable in young adults. Depending on passed studies, a study model for the relationship of each variable was founded and the moderated mediation effect was checked. We performed a survey on 400 young adults using SNS through an online survey, and finally, a total of 351 data were employed for analysis. The outcome of the analysis was as follows. First, contingent self-esteem, SNS upward comparison, SNS usage motivation, and inferiority feelings were all affirmed to reveal a positive correlation. Second, contingent self-esteem had an important impact on inferiority feelings, which was mediated by SNS upward comparison. Third, the relationship between SNS upward comparison and inferiority feelings was moderated by SNS usage motivation. Finally, SNS usage motivation moderated the indirect effect of contingent self-esteem on inferiority feelings via SNS upward comparison. Based on the results of this study, we presented the psychological and emotional implications that can experience the inferiority feelings in young adults.

Sample size calculation is very important in clinical trials. In this paper, we propose sample size calculation method for non-inferiority trials using sample size calculation method suggested by Wang et al.(2003) based on Wilcoxon's rank sum test. Also, sample size comparison between parametric method and proposed method are presented.

Normal approximation methods under the null hypothesis of no difference are frequently used to test the two independent proportions in non-inferiority trials. However, these tests are not appropriate under the null hypothesis of non-zero difference. We review the likelihood score methods proposed by Miettinen and Nurminen, Farrington and Manning, and Gart and Nam and compare the performance of these tests. The simulation study shows that the likelihood score tests under the null hypothesis of non-zero difference have better performance at a Type I error and power than usual normal approximation methods.

Non-inferiority trials indicate whether the effect of an experimental treatment is not worse than an active control. Chen et al. (2006) and Kang (2010) proposed a test method for non-inferiority trials using confidence intervals. In this paper, we suggest a new nonparametric method using a confidence interval based on Wilcoxon rank-sum test and Hodges-Lehmann estimator of active control. A Monte-Carlo simulation study compares the type I error and the power of the proposed method with previous methods.
