  • We propose some properties for fuzzy hypothesis test by fuzzy significance probability. First, we define fuzzy number data and fuzzy significance probability for repeatedly observed data with alternated error term. By the agreement index, we compare fuzzy significance probability with significance level and drawing conclusions the degree of acceptance and rejection by agreement index.

  • Purpose: The purpose of this study was to identify the degree of attaining a smoking cessation goal when an agreement on means to achieve smoking cessation among male college student smokers was established. Method: This study was planned as a nonequivalent control group non-synchronized design and the sample was divided into an agreement group and a comparison group by convenience sampling in a college of G city. The data was analysed with SPSS Win10.0 using a Likelihood $x^2-test$, Odds ratio, Paired t-test and ANCOVA. Result: The theory that the degree of smoking cessation will be higher in the agreement group than the Comparison group was rejected (${\delta}$ = 2.567, p = .055). The theory that nicotine dependency will be lower in the agreement group than the comparison group was supported (F = 3.965, P = .049); however, the theory that the number of cigarettes smoked per day will be lower in the agreement group than the comparison group was rejected (F = 1.342, p = .252). Conclusion: It has been shown that an agreement on means to achieve smoking cessation goals is a key factor to success in quitting smoking.

  • Agreement analysis is conducted to assess reliability among rating results performed repeatedly on the same subjects by one or more raters. The kappa statistic is commonly used when rating scales are categorical. The simple and weighted kappa statistics are used to measure the degree of agreement between two raters, and the generalized kappa statistics to measure the degree of agreement among more than two raters. In this paper, we compare the performance of four different generalized kappa statistics proposed by Fleiss (1971), Conger (1980), Randolph (2005), and Gwet (2008a). We also examine how sensitive each of four generalized kappa statistics can be to the marginal probability distribution as to whether marginal balancedness and/or homogeneity hold or not. The performance of the four methods is compared in terms of the relative bias and coverage rate through simulation studies in various scenarios with different numbers of raters, subjects, and categories. A real data example is also presented to illustrate the four methods.

  • The purpose of this study is to investigate the Korean's value of children and perception of parenting difficulty through the agreement to the three kinds of Korean proverbs: difficulty of parenting, preference of son and value of daughter. Also, this study attempted to identify whether the value of children and the perceived difficulty of parenting measured by the agreement of the proverb is related to the number of children they thought as ideal before marriage and the number of children they actually have. Total 385 married men and women who have a job participated in the survey. Main result is as follows. 1) In most cases, the ideal number of children was at least equal or more than the actual number of children. 2) The subjects showed higher degree of agreement to the proverbs regarding the difficulty of parenting than the preference of son or the value of daughter. 3) The degree of agreement to each kind of proverbs were different in terms of some demographic variables such as age and sex. 4) When the age effect controlled, the ideal number of son had correlation with the agreement to the son-preference proverbs while the ideal number of daughter or total children had no correlation with agreement to any kinds of proverb. The actual number of son was positively correlated with agreement to the son-preference proverbs while actual number of daughter was negatively correlated with it. In conclusion, this study suggests the Korean's value of children has been rapidly changing and it has, in part, an effect on the number of children they want to have or they actually have.

  • Korean proverbs concerning parent child relationships were collected from literature. 95 proverbs were selected for this study. The proverbs were categorized by meaning; value of child, affection toward child, boy-preference, positive-negative affection coward daughter, importance of child's education, child-rearing stress, identification of parent, authoritative control, and filial piety. The subjects (223 married men and 224 married women) were asked to indicate their understanding of the meaning of the proverbs. The degree of agreement was analyzed. The results revealed variability in their understanding and the high degree of agreement on the proverbs. Demographic variables, age, educational level, and religion, appeared to be the important factors in the subjects' agreement.

  • We propose some properties for a fuzzy correlation test by reduced-spread fuzzy variance for sample fuzzy data. First, we define the condition of fuzzy data for repeatedly observed data or that which includes error term data. By using the average of spreads for fuzzy numbers, we reduce the spread of fuzzy variance and define the agreement index for the degree of acceptance and rejection. Given a non-normal random fuzzy sample, we have bivariate normal distribution by apply Box-Cox power fuzzy transformation and test the fuzzy correlation for independence between the variables provided by the agreement index.

  • 본 연구는 간 초음파 영상을 활용하여 정량적인 측정 분석을 통해 조직 내 감쇠 지수, 조직 내 산란 분포지수 값 분석과 함께 초음파 영상 소견 간 일치도를 알아보고자 하였다. 2022년 8월부터 2022년 10월까지 지방간이 의심되어 간 초음파 검사 처방을 받은 45명의 환자를 대상으로 간 초음파 검사를 시행하였다. 연구결과, 초음파 영상 소견과 조직 내 감쇠 지수 간 일치도 분석 결과 Kappa 값이 0.82(p<0.05)로 두 검사 방법 간 매우 높은 일치도를 보였다. 또한, 초음파 영상 소견과 조직 내 산란 분포 지수 간 일치도 분석 결과에서도 Kappa 값이 0.642(p<0.05)로 두 검사 방법 간 높은 일치도를 보였다. 지방간 예측 시 간 초음파 소견 및 정량적인 초음파 검사 기법인 조직 내 감쇠 지수, 조직 내 산란 분포 지수를 활용한다면 지방간 환자의 진행 정도를 판단할 때 도움이 될 수 있을 것으로 생각된다.
