In this study, the characteristics of body type of Chinese-korean Women between 15 and 17 Years Old Living in China were reviewed by analysing factors and groups in order to provide basic data required to research body types. The following are study results. 1. The study examined average, standard deviation, the minimum value and the maximum value of the 72 items gained from measuring Chinese-korean women between 15~17 years old living in China, and found that 21 items showed more than 4.0 standard deviation among the entire measurements. 2. The current study conducted a factor analysis for the 72 items in order to extract and compare components of body types among Chinese-korean women between 15~17 years old living in China. As a result, 9 factors were extracted, and characteristic values were ranged from 1.15 to 24.71 while the accumulated contributory rate was 75.98%. 3. Chinese-korean women between 15 and 17 years old living in China were classified into three types. Among the 72 items, it was observed that there were differences among groups in 64 items including 15 height items, 10 width items, 16 circumference items, 5 thickness items, 17 length items and weight, excluding neck width, head thickness, shoulder angle, head height, face length, waist back length, scye depth and waist to kip length. 4. As a result of proportion comparison using body indexes of Korean women between 15 and 17 years old living in China and Korea, it was found that, in height item, when regarding the height as 100, Korean women between 15 and 17 years old living in China tended to have longer lower half of the body in relation to the height compared to the Korean.

Previously sailing yachts or leisure yachts were mainly made from FRP(Fiber glass reinforced plastic) in the small shipbuilding, but recently there is a trend to replace it for steel or aluminum to substitute FRP for environmental friendly materials. Although It have to need a many checked item in case of hull girder strength and transverse strength normally evaluate base on calculation of class guideline so called direct calculation method. Otherwise. this method of initial structural design considered enough for safety margin on the structure. But, case of small craft must consider for evaluating local strength through rational method. In this paper, check the bow structure members for satisfying results base on allowable stress criterion of damaged bow structure by dynamic load due to slamming and bottom impact load due to pitching motion through finite element analysis. and investigate engine bed structure considering engine weight load and transverse wave load.
Objectives : The purpose of this study was to develop the Korean Strength Scale and to examine its validity and reliability. Methods : The Korean Strength Scale is a self-report questionnaire that measures 25 valued strengths and is comprised of 124 items ; each item had a 0-5 rating on a 6-point scale. In order to test validity and reliability, data were collected from 355 adults. The measures included the Korean Strength Scale, HEXACO Personality Inventory (HEXACO-PI), Satisfaction with life scale (SWLS), Positive Affect and Negative Affect Schedule (PANAS), and Orientations to Happiness Questionnaire (OHQ). Results : The resulting exploratory factor analysis of the Korean Strength Scale suggested 4 factor structures. The Korean Strength Scale was shown to have acceptable psychometric properties, including acceptable internal-consistency reliabilities, factorial validity, and high convergent correlations. Conclusion : Although there is room on improvement for some facet scales, the Korean Strength Scale appears to be a useful tool for assessing an individual's signature strengths.
The purpose of this study is to develop a multi-dimensional scale measuring consumers' perceived challenge in shopping fashion products online, and to verify its validity and reliability. Relevant literature is first reviewed to identify possible dimensions of perceived challenge. Next, Study 1 is conducted in order to explore the dimensions empirically and to see whether the dimensions that emerged were consistent with prior findings. A total of 190 responses to an open-ended question was qualitatively analyzed by using content analysis. The findings of Study 1 generate 26 items reflecting four dimensions (i.e., product knowledge, previous experience, website functionality, and product availability), which correspond to the dimensions suggested in literature review. Study 2 is subsequently conducted to refine the items so that the perceived challenge scale establishes cross-validation, convergent validity, discriminant validity, reliability, and predictive validity. A total of 238 responses is quantitatively analyzed by using exploratory factor analysis, confirmatory factor analysis, and structural equation modeling. In the results of Study 2, the perceived challenge scale is found to consist of a total of 16 items reflecting three dimensions: E-commerce Challenge (corresponding to Previous Experience reported in Study 1), Retailer Challenge (corresponding to Website Functionality), and Product Challenge (corresponding to Product Knowledge); all Product Availability items have been eliminated through the item refinement process. Specifically, E-commerce Challenge and Retailer Challenge are found to predict flow, supporting flow theory, while Product Challenge fails to lead to flow significantly. Implications, limitations, and suggestions for future studies are also discussed.
The service quality survey for the customers of Gwangyang container port has been done since 2005. It has been difficult to compare annual levels or rival ports because the calculation of weights among service dimensions that is the most important procedure of the assessment systems did not be founded. In particular, the calculation results by the Analytical Hierarchy Process that specializes in estimating the weights were very unstable and not comparable because they were fluctuated annually more than 90% for the specific item. The objective of this study is to support the establishment for new assessment system of service quality with cost- and time-effective tools at Gwangyang port. The confirmatory factor analysis methodology applied to 2007-2009 survey data from the customers of Gwangyang port can estimate ex-post weights to measure annually the stable service quality. The proposed methodology allows us to build the assessment system of more scientific and accurate service quality while reducing the survey items. By this study, a port company can measure accurately the quality of service and improve its competitiveness through being compared to previous periods and leading companies.

Extreme sports refers to sports activities with a high level of inherent danger, such as extreme skiing, snow-boarding, mountain biking, motocross bicycling, aggressive in-line skating, wake-boarding, and paragliding. This study investigates the characteristics of extreme sports participants as group identities through an examination of the differences between extreme sports participants and traditional sports groups in lifestyle and sportswear benefits sought. We composed a total 108-item lifestyle profiles characterized by six lifestyle dimensions (dress, diet, home, recreation, consumption, and sense of values); in addition, we developed 32 items for sportswear benefits sought. The surveys targeted 422 sports participants living in Korea (216 men and 206 women, aged 15-23): 119 extreme sports participants and 303 traditional sports participants. All items were evaluated on a 5-point Likert scale, and SPSS 17.0. was used for data analysis. Exploratory factor analysis was conducted to confirm the substructure of each lifestyle dimension and sportswear benefits sought. The results of the factor analysis on each lifestyle dimension are as follows: 5 factors in dress dimension, 4 in diet, 3 in home, 6 in recreation, 5 in consumption, and 6 in sense of values. Six factors of sportswear benefit sought were identified. A t-test revealed that there were significant differences between the two groups in lifestyle dimensions and sportswear benefits sought. This study reveals that the lifestyle characteristics of extreme sports participants are more likely than traditional sports group to be more self-expressive, more distinctive, more fashion-oriented, more conspicuous, and more brand-oriented, while preferring more active sports, more dynamic leisure, and a more sensible life. Another finding is that extreme sports participants seek the distinctive, conspicuous, and latest sportswear benefits.
Objectives: The purpose of this study was to investigate the opinions of Korean dental hygienists on the Korean advanced dental hygienist system in Korea. Methods: The survey was conducted on 328 dental hygienists working at dental clinics and hospitals in Seoul, Gyeonggi-do, Incheon, and Chungcheong-do. Collected data were analyzed with the frequency analysis, independent-samples t-test, and one-way analysis of variance after their reliability and validity were verified through the reliability, exploratory factor, and confirmatory factor analyses. Results: Respondents preferred sectoral advanced dental hygienists to integrated advanced dental hygienists, but 47.0% of respondents did not respond to this questionnaire item. To become an advanced dental hygienist, 'more than 5 years but less than 8 years' of clinical experience was appropriate according to 45.7% of the respondents and 'more than 30 h but less than 40 h' of training period was appropriate according to 25.9% of the respondents. Respondents thought that the duration of the training period for advanced dental hygienists would be directly proportional to expectations from the effect of advanced dental hygienists (p=0.023). Further, respondents who were usually interested in advanced dental hygienists showed higher expectations from the role (p<0.001) and effect (p<0.001) of advanced dental hygienists than those who were not interested. Conclusions: This study suggests various implications of the introduction of the advanced dental hygienist system in Korea.

Purpose: The purpose of this study was to evaluate the psychometric properties of the Hypertension Self-Care Behavior Scale for older adults with hypertension in Korea. Methods: A cross-sectional descriptive study was used with 196 participants. Translation and back-translation were performed by bilingual nursing professionals and a nutritionist. Reliability and validity such as content validity, construct validity, and concurrent validity were conducted. To evaluate the concurrent validity, the correlation coefficients between the Korean version of Hypertension Self-Care Behavior and concurrent scales (hypertension adherence scale and self-efficacy scale) were calculated. Results: The total 20 items for the Korean version of the Hypertension Self-Care (HBP-SC) Behavior Scale were retained during item-analysis. In explanatory factor analysis, a two-factor solution was proposed and the two factors named, 'HBP-SC Diet behavior' and 'HBP-SC Health behavior (except diet)'. The two factors accounted for 48.9% of the variances. The Korean version of the Hypertension Self-Care Behavior Scale correlated with concurrent variables such as hypertension adherence and self-efficacy. For reliability of the Korean version of the Hypertension Self-Care Behavior, Cronbach's ${\alpha}=.92$. Conclusion: Findings show that the Korean version of the Hypertension Self-Care Behavior is reliable and valid for measuring self-care behavior of older adults with hypertension.

Background: Reliable and validated instruments are needed in order to study the quality of life in myeloma patients. This study aimed to translate and explore the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) myeloma module (QLQ-MY20) in Iranian patients. Materials and Methods: Two hundred and fifteen patients with multiple myeloma (MM) were recruited from Imam Khomeini Hospital, Tehran. A standard forward-backward translation procedure was implemented. Participating patients were asked to complete the EORTC QLQ-C30 and the QLQ-MY20 three times, at study entry, after two weeks, and again after three months. Data were tested for the range of measurement, internal consistency, test-retest reliability, known group comparison, responsiveness and factor structure. Results: Mean age of the patients was 60.7 years. No floor and ceiling effects were seen for the QLQ-MY20. Cronbach's ${\alpha}$ was greater than 0.80 for all three multi-item scales (ranging from 0.82 to 0.93). All four scales had test-retest reliability of 0.85 or greater. Results of the confirmatory factor analysis that the hypothesized 3-scale measurement model of the QLQ-MY20. Moreover, the Persian version for the QLQ-MY20 differentiated between subgroups of the patients in terms of beta-2 microglobulin, fracture and performance status. The responsiveness of the QLQ-MY20 to change over time was confirmed within 3 months. Conclusions: the results of our study indicate that our Iranian version of the QLQ-MY20 is a feasible, reliable and valid questionnaire for assessing the condition-specific quality of life of patients with MM.
The purpose of this study was to describe 20's to 30's men's fashion lifestyle and develop clusters in grooming related variables. We also tried to interpret profile of clusters, and determine the difference between different level of grooming clusters in appearance care behaviors, and clothing behaviors such as clothing selection, preference of clothing image and design in men's wear. Data was obtained using the survey methods by convenience sampling. Frequency analysis, factor analysis, cluster analysis, chi-square test, and t-test were used for analysis using SPSS 18.0. The result of factor analysis of men's lifestyle show that 5 factors are extracted. Two different clusters were formed after the K-means cluster analysis. We realized that the level of grooming activity is significantly associated with the young men's major expenditure item, and beauty/care items, and the reason for exercise. The level of grooming was strongly associated with clothing selection behaviors. In addition, there is a significant difference in preferred image between two different grooming groups. In the feminine image, HG group favored more than LG group. The preferred design was associated with the degree of grooming as well. Unique and stylish top and bottom styles such as cargo, hiphop, and boots cut were favored more by HG group than LG group. We suggest that we can do market segmentation by the degree of the grooming activity, considering the current men's taste and trend to extend market share.
