The chi-square type test statistic is the most commonly used test in terms of measuring testing goodness-of-fit for multinomial logistic regression model, which has its grouped data (binomial data) and ungrouped (binary) data classified by a covariate pattern. Chi-square type statistic is not a satisfactory gauge, however, because the ungrouped Pearson chi-square statistic does not adhere well to the chi-square statistic and the ungrouped Pearson chi-square statistic is also not a satisfactory form of measurement in itself. Currently, goodness-of-fit in the ordinal setting is often assessed using the Pearson chi-square statistic and deviance tests. These tests involve creating a contingency table in which rows consist of all possible cross-classifications of the model covariates, and columns consist of the levels of the ordinal response. I examined goodness-of-fit tests for a proportional odds logistic regression model-the most commonly used regression model for an ordinal response variable. Using a simulation study, I investigated the distribution and power properties of this test and compared these with those of three other goodness-of-fit tests. The new test had lower power than the existing tests; however, it was able to detect a greater number of the different types of lack of fit considered in this study. I illustrated the ability of the tests to detect lack of fit using a study of aftercare decisions for psychiatrically hospitalized adolescents.

The purpose of this research was to determine the relation between clothing evaluative criteria and personality types. Primary factor analysis was used to classify the clothing evaluative criteria and the continual scores of Myers Briggs Type Indicator (MBTI) were used for classifying the personality types. Correlation analysis and multiple regression analysis were used to determine the relation between the clothing evaluative criteria and the personality types. The data for this research were collected from questionnaires of 309 female university students in Seoul. In the results, the clothing evaluative criteria were grouped into 4 underlying dimensions： practical, situational, appearance producible and symbolic. Partially significant relations between the 4 clothing evaluative criteria and the 4 indicators of MBTI personality types were found through correlation analysis. Multiple regression analysis revealed that the variables explaining the dimension of Sensing and Intuition (SN) were appearance producible and symbolic clothing evaluative criteria; the appearance producible criterion had an inclination toward Intuition while the symbolic criterion had an inclination toward Sensing. The variable explaining the dimension of Judging and Perceiving (JP) was situational clothing evaluative criterion, which had an inclination toward Judging.

This study analyzes the effect of clothing involvement using meta-analysis. Metal-analysis (the analysis of analyses) is widely used in various academic areas to integrate individual empirical studies and generalize the knowledge of a specific research field. Previous studies regarding clothing involvement published since 1990 were researched from the KISS database using clothing involvement and fashion involvement as a keyword; subsequently, 127 articles were identified. Studies that had insufficient statistics or included clothing involvement as a moderating (or intervening variable) were eliminated; subsequently, 36 articles provided a total of 75 data sets that were used for the final analysis. Dependent variables were grouped into 10 categories to compare the differences between high and low involvement groups. The effect size of clothing involvement was large in non-personal information source; however, it was small in utility, brand royalty and quality. In the 7 categories of relational studies that showed homogeneity, the relation size regarding conformity was smaller than the personal information source.

The nucleotide sequences of the internal transcribed spacer (ITS) regions of the ribosomal DNA including the 5.8S ribosomal RNA gene (rDNA) have been determined for 11 species in order to analyze their intrageneric relationships. The total length of these sequences ranged from 530 nucleotides for Trichoderma reesei KCTC 1286 to 553 nucleotide for Trichoderma koningii IAM 12534. Generally speaking, the length of ITS1 region was about 30 nucleotides longer than that of the ITS2 region. Also, the sequences of 5.8S rDNA were more conserved in length and variation than those of ITS regions. Although the variable ITS sequences were often ambiguously aligned, the conserved sites were also found. Thus, a neighbor-joining tree was constructed using the full sequence data of the ITS regions and the 5.8S rDNA. The Trichoderma genus used to be grouped on the basis of the morphological features and especially the shape of phialides needs to be reexamined. The phylogenetic tree displayed the presence of monophylogeny in the species of Trichoderma. Therefore, it was difficult to distinguish the intrageneric relationships in the Trichoderma genus.

This study examines the furniture usage behavior of the apartment dwellers in tile city of furniture usage by resident’s characteristics, such as floor space size, household income, the stage of family life cycle and housewife’s age. To this end, interviews were conducted with 304 individuals, either household heads or their spouses living in three residential areas in Seoul. The sample was selected among people living in apartment units with the 30s and 40s pyong of floor space size.The major findings of this study are as fllows ; The furniture and furnishings selected for the study are grouped into four clusters such as conversation-space components, ordinary decoration, high-quality decoration and miscellaneous components. Families in the stage of primary school life cycle were likely to possess fewer furniture and decorations than those in the stage of high school life cycle and in the launching stage. Younger housewives are less likely to possess ordinary and high-quality decorations than the older. Those living in the larger apartment units are likely to decorate their living room in an ornamental rather than functional way, and to possess more ordinary and high-quality decorations than those in the smaller. In this study, the size of floor space appers a variable most powerful to explain the pattern of furniture usage.

Although an extensive body of research exists on sports uniform colors in the West,there is a dearth of research on South Korean sports uniforms, especially in the domain of professional teams ports. This study aims to identify and analyze the colors of sports uniforms of 56 professional teams listed on the Korea Professional Sports Association (KPSA) for a range of team sports (e.g. football, baseball, basketball, volleyball, and golf). The number of colors of each team's uniform and the ordinal ranking of these colors were recorded and analyzed. Furthermore,the number of colors and parent company colors were grouped by gender and league. Overall, 80.4% of the teams preferred three to four colors with white, black, blue, and red being the most popular colors. Every team's primary, secondary, or graphic logo colors on their uniforms included white. The gender variable was partially significant, emphasizing culturally significant colors such as pink. The parent company's color showed a significant connection with the team's uniform colors. This result was related to the historical origins of South Korean professional team sports and their unique relationship with chaebols. Based on the findings, this study concludes that visibility and contrast factors, as well as historical aspects relating to the concept of glocalization play an important role in the color choices of South Korean team uniforms.

Purpose: To evaluate the overall results and its major affecting factors(athlete/associated injury) of modified Brostrom procedure for chronic ankle lateral instability. Materials and Methods: Fifty-one patients (51 ankles) with chronic ankle lateral instability were sub-grouped athletes and non-athletes and again sub-grouped with associated injury and without associated injury. Associated injuries were osteochondral defect(6), peroneal tendon abnormality(10), os subfibularae(4), os subtibialae(4), anterior impingement(5) and loose body(2). The overall surgical results were evaluated and also see whether or not athletes and associated injury affect the result. Result: Of the 51 operations performed, there were 39 excellent, 8 good and 4 fair as a whole. Of the 24 athletes operated, there were 19 excellent, 3 good, and 2 fair. Among the 27 non-athletes, there were 20 excellent, 5 good and 2 fair results. The average time to ordinary life in the non-athlete group was 2.5 months and average time to sports activity in the athlete was 4.5 months postoperatively. Those who didn't have any associated injury had all excellent result, on the contrary, those who had associated injuries, 14 excellent, 8 good and 4 fair results. All the fair results were associated with osteochondral lesion of talus. Whether or not the patient is athlete does not affect the surgical results, but whether or not there were associated injuries does affect the surgical results. Conclusion: Modified Brostrom procedure for chronic ankle lateral instability itself is an excellent to good operation. This procedure can be used in athletic populations who need high demand of sports activity. But chronic ankle lateral instability with associated injury group showed variable, less satisfactory results than those without associated injury. Careful preoperative and intraoperative examination should be done to find out the associated injury with chronic ankle lateral instability.
