Purpose: This study compared the effectiveness of three methods, fascial distortion model (FDM), myofascial release (MFR), self-myofascial release (SMR), on the neck range of motion and pain. Methods: In this study, the collected data were processed statistically using SPSS version 22.0 for Windows. Descriptive statistics were used to analyze the general characteristics of the subjects. Repeated measure ANOVA was conducted to analyze the range of motion of the neck of the group and VAS, and Contras was used to see the difference in significance over time. One-way ANOVA was used to compare the differences among the groups and a post-hoc test was used. The significance level (${\alpha}$) was 0.05. Results: In the range of motion, the flexion and extension of the neck, right rotation, and left rotation were significantly different in the SMR, FDM, and MFR groups. The right lateral flexion showed significant differences in the FDM, MFR, and SMR groups. The VAS was similar in the groups at 2 and 4 weeks, but there was a significant difference among the FDM, MFR, and SMR groups at 6 weeks. Conclusion: In this study, MFR and MSR as well as FDM were effective in controlling the range of motion and pain control of the neck. Further studies will be needed to determine the effects of long-lasting treatments other than pain control. These studies and the present study will be used as a basis for ongoing research into the duration and method of application for musculoskeletal therapies.

Degenerative arthritis is a common joint disease that affects many elderly people and is typically diagnosed through radiography. However, the need for remote diagnosis is increasing because knee pain and walking disorders caused by degenerative arthritis make face-to-face treatment difficult. This study collects three-dimensional joint coordinates in real time using Azure Kinect DK and calculates 6 gait features through visualization and one-way ANOVA verification. The random forest classifier, trained with these characteristics, classified degenerative arthritis with an accuracy of 97.52%, and the model's basis for classification was identified through classification algorithm by features. Overall, this study not only compensated for the shortcomings of existing diagnostic methods, but also constructed a high-accuracy prediction model using statistically verified gait features and provided detailed prediction results.

The purpose of this study was to examine the influences of their money attitudes to spending behaviors of middle, high, and college students. The total number of students selected for this study were 1,252. Factor analysis, Cronbach' ${\alpha}$, two-way ANOVA, Duncan' multiple range test, Pearson correlation analysis, and multiple regression were used for statistical analysis. The results were summarized as followings: 1) The tendency of attitude that money is good was highest. Also, the tendency of attitude that money represents freedom and power was slightly high. On the other hand the attitudes that money represents achievement, and that money is evil were low. Especially the attitude that money represents respect was lowest. 2) Resulting from two-way ANOVA, the attitudes that money is good and represents achievement showed significant interaction effects between sex and age. The altitude that money is good showed significant differences by sex especially among middle and high school students. The altitude that money represents achievement showed significant differences by age among the male students. Three types of attitudes that money is evil, money represents respect, and money represents both freedom and power showed significant main effects in different age groups. Also the attitude that money represents freedom and power showed significant main effect by different sexes. 3) Four different types of measuring spending behaviors scored slightly low mark. 4) Resulting from two-way ANOVA, four different spending behaviors showed significant difference only by sexes and ages. Planned spalding behavior and conscious spending behavior showed significant differences in ages and sexes separately. While impulsive spending behavior by different age groups resulted in significant differences. Excessive spending behavior by sexes resulted in significant differences. 5) Regression analysis showed that planned spending behavior had the linear relationships in no, sex, self-esteem, and attitude that money is good. Conscious spending behavior had the linear relationships in ses, and attitudes that money represent achievement. respect, and freedom. Impulsive spending behavior had the linear relationships in age, self-esteem, and attitudes that money is good and that money is evil, and attitude that money represent freedom, Excessive spending behavior had the linear relationships in sex, self-esteem, and attitudes that money represent achievement, respect and freedom.

This study aims to explore age-related differences with the assessment tools in the web-based 3D virtual model house and to propose the 3D model house criteria which everyone can use easily. The participants came from three age groups, ranging from their 20s to their over 40. Presence, Usability and Space perception and cognition in the experiment for navigating and evaluating the web-based 3D model house were measured and compared through one-way ANOVA and two-way ANOVA. The results and conclusions are as follows. (1) The younger the participants were, the more positive they evaluated the experiment on Presence. However, 20s needed higher presence than other two groups. (2) 30s and over 40 groups evaluated that the 3D virtual model house was more efficient than an actual model house on Usability. When the participants were younger, the values of 'expressivity' factor were higher. (3) The younger the participants were, the more positive they perceived the virtual environment (VE) on Space perception and cognition scale. There were no significant differences in the selection of dwelling size and the floor plan type. There were no significant differences of interaction effects between age and online gaming experience on Presence and Usability. The results of the current study demonstrate that there are differences among age groups and older groups have difficulty navigating and assessing in a VE. Although older groups take longer to adapt in the VE, they regard the 3D model house as an effective tool for purchase of house.

Objectives: This study assessed the effect of water storage on the flexural strength (FS) of low shrinkage composites. Materials and Methods: A total of 165 bar-shaped specimens ($2{\times}2{\times}25mm$) were fabricated of 2 low shrinkage composites (Filtek P90 [3M ESPE], GC Kalore [GC International]) and a conventional methacrylate-based composite (Filtek Z250 [3M ESPE]). The specimens were subjected to 3-point bending test at 6 time intervals, namely: immediately after curing, at 24 hours, 1 week, 1 month, 6 months, and 1 year following storage in wet and dry conditions. The FS of the specimens were measured by applying compressive load at a crosshead speed of 1.0 mm/min. Data was analyzed using 3-way analysis of variance (ANOVA) and Tukey's test. Results: Three-way ANOVA revealed significant interactions between time, type of composite, and storage condition (p = 0.001). Tukey's multiple comparison test revealed significant reductions in FS of all composites after 6 months and 1 year of storage in distilled water compared to dry condition. Conclusions: Filtek P90 showed the highest and GC Kalore showed the lowest FS after 1 year storage in distilled water. The immediate high strength of Filtek Z250 significantly decreased at 1 year and its final value was lower than that of Filtek P90.
