For fit satisfaction evaluation, the subjects were asked to put on the jackets from the seven manufacturers in random order, view how the jackets fit in a full-body mirror and answer questions regarding fitting in 22 specific areas, including the neck, shoulders, waist, hips and arms, as well as eight questions related to maneuverability. The surveys and evaluations were conducted between October 2007 and November 2008, and the compiled data were analyzed using the SPSS 14.0 statistics program. The One-way analysis of variance was performed to comparatively analyze the differences among the products from the seven manufacturers. Post-hoc tests were performed based on Duncan's test for the criteria that displayed significant differences. The results were summarized as follows. Fit evaluations were performed for the size 88 formal jackets from the seven manufacturers. All items, except the center front line, displayed significant differences at p<0.05 or higher among the manufacturers. The age group 20-39 felt that the main problems were in the shoulder, armscye, upper arm, waist, abdomen and hip areas. Modifying the shoulder area, armscye depth and hip areas severely compromises the jacket's balance, and attention to these areas must be given developed pattern design.

Purpose: This study was done to test the validity and reliability of the Adolescent Mental Problem Questionnaire (AMPQ) for Korean high school students. Methods: The AMPQ was designed to assess adolescents', mental health status and problem behavior (Ahn, 2006). A methodological study design was used with exploratory factor analysis, Pearson's correlation coefficients, and a fitness of the modified model for validity. Also, Cronbach's alpha coefficients and alternative-form method for reliability were used. AMPQ was tested with a sample of 36,313 high school students. The participants consisted of 18,701 males and 17,612 females. Results: Seven factors were extracted through factor analysis: 'Psychiatric problems', 'Delinquency', 'Academic troubles', 'Family problems', 'Hazardous behavior', 'Harmful circumstance', 'Eating problems'. These factors explained 51.1% of the total variance. The fitness of the modified model was good ($X^2$=38,413.76, Goodness of Fit Index [GFI]=.94, Adjusted Goodness of Fit Index [AGFI]=.93, Comparative Fit Index [CFI]=.95, Root Mean Square Error of Approximation [RMSEA]=.05), and concurrent validity with Korea-Youth Self-Report [K-YSR] was .63. Cronbach's alpha coefficient of the 31 items was .85. Conclusion: The results of present study suggest that the modified AMPQ instrument may be useful for efficiently assessing mental health status and problem behavior in late adolescent, high school students.

The Y generation born between 1981 and 1995 is the largest consumer group in the United States. This study is to provide an insight of understanding Y generation's decision factors of purchasing Jeans and the fit issues. This study investigated their purchasing decisions factors, including fit, cost, brand, color, and the media/internet influences. It is revealed that the Y generation might have access to the internet, but they still rely more on their peers and savvy skills to decide what they purchase. They preferred to shop from the land based retail stores rather than the internet. The fit was the most important factor of their purchasing decision, but less concerns of the brand. In this study, 87% of them chose "fit" as the reason to buy a pair of jeans. Fit problems were related to the price category. This study suggests apparel manufacturers should understand Y generation's fit issues in the global market.

The recent fashion market failed to satisfy the needs of female customers in their 30s who are demanding a slim jacket that makes the wearer look young and slim. Accordingly, the slim-fit jackets of domestic brands targeting the women in their 30s were collected to conduct look and movement fitting evaluations based on the standard somatotype, and a slim-fit tailored jacket prototype was developed based on the present findings. This research aims to increase the satisfaction level of the slim-fit jacket customers reflecting a variety of somatotypes of women in their 30s. The research process was developing jacket patterns fully reflecting the properties in terms of extra space and design lines for different somatotypes of women in their 30s based on the jacket pattern formulated through the advanced research, and then suggesting pattern design methods for the different somatotypes. In this sense, this research attempted to identify the problems concerning the slim-fit tailored jacket fitting for different somatotypes of women in their 30s. The main aim was to suggest ways to improve the customers' satisfaction level regarding the fit, and enable the manufacturers to produce a well-fitting jacket reflecting the peculiarities of each somatotype.

As directly imported apparel brands are actively entering the domestic market, studies of the marketing aspects of these imported apparel products and their overall consumption trend have been done. However, studies of whether are not the directly imported apparel products provide Korean consumers with an appropriate fit are not as common. Therefore, this study investigates the satisfaction with and problems associated with the fit along with the recognition of and preference for directly imported US apparel brands. 100 female college students who purchased directly imported US apparel brands participated in a survey. The results of this survey showed that their recognition of, preference for, possession rate of and satisfaction with the directly imported US apparel brands tend to be high. The major purchasing motivations were the excellent 'design' and 'color' of the products. The subjects reported that they were satisfied with the quality of 'materials' and 'sewing condition'. However, they were not satisfied with the 'comfort' or the 'size'. Their level of satisfaction with the fit of these products differed depending on the specific item. Their level of satisfaction with the fit of T-shirts and knits was high, whereas the level for pants was relatively low. They complained mostly about the sleeve length and garment length of upper-body garments and coats. They were not satisfied with how the pants fit. The areas of dissatisfaction regarding the pants were the waist girth, the crotch length and the pants length.

The new better than used failure rate (NBUFR), Abouammoh and Ahmed (1988), and new better than average failure rate (NBAFR) Loh (1984) classes of life distributions, have been considered in the literature as natural weakenings of NBU (NWU) property. The paper considers testing exponentiality against strictly NBUFR (NBAFR) alternatives, or their duals, based on goodness of fit approach that is possible in life testing problems and that it results in simpler procedures that are asymptotically equivalent or better than standard ones. They may also have superior finite sample behavior. The asymptotic normality are proved. Powers, Pitman asymptotic efficiency and critical points are computed. Dealing with censored data case also studied. Practical applications of our tests in the medical sciences are present.

The NDT(Non-Destructive Testing) is valid for the defect detection of rolling stocks because it can be used to detect the defect in many invisible parts. For example, fatigue cracks are initiated in press fit parts that suffer from fretting fatigue damage such as the wheel seat and the NDT technique can detect those cracks. But the conventional ICFPD method can not apply to detect such cracks in press fit parts of the axle by some technical problems. In this study, we have introduced the new concept ICFPD method that can be applied in press fit parts of the axle. And we have shown the basic techniques of FEM about the new concept ICFPD method.

A brake system in automobile is one of the important parts that directly affect the safety of passengers. Particularly, disk brake module is applied to almost all kinds of automobile brake system due to its remarkable braking power and braking distance. In the disk brake module of an automobile, the bolt for tire wheel is assembled to the disk brake hub by interference fit(bolt pressing process). The process induces small deformation whose range is within tens of ${\mu}m$ and this deformation may cause the runout badness of the whole disk brake module, and even braking problems such as judder or squeal phenomena which makes the loss of braking efficiency. In this study, bolt pressing fit into hub was simulated by $ANSYS^{TM}$, a commercial structure analysis program. Also, the aspect and the cause of hub displacement were analyzed and the solution for decreasing runout of hub was proposed.

Purpose: This study was done to identify the relationship between goodness-of-fit for mother-preschool child dyads and parenting stress experienced by the mother. Methods: Study participants were 500 mothers who had children aged 3 to 5 who attended one of ten kindergartens or infant schools in M City or B City. Descriptive statistics and Pearson's correlation coefficients were calculated using the SPSS program. Results: Comparison of goodness-of-fit scores for mother-preschool child dyad according to the characteristics of the participants, showed a significant difference according to child's age, gender, and birth order, mother's education and occupation, father's age and education, family income, and the chief caregiver in the family. There was a positive correlation between goodness-of-fit scores for mother-child dyad and parenting stress scores for mothers. Conclusion: The findings of the study indicate a need to identify differences between children's behavioral problems and parenting styles according to the degree of discord in the mother-child temperaments. It is also necessary to develop and apply nursing programs to promote harmonizing of temperaments, programs in which the characteristics of the child and the mother are considered.
