  • The purpose of this study was to assess the concurrent validity and reliability of goniometric measurement of joint motion. Subjects were 40 healthy university students. Measurements were performed by 4 inexperienced physical therapy students. Four different instruments were used and three readings were taken with each instrument in random order making a total of 12 readings for flexion of the right elbow of each subject. Goniometers used were 1. universal 2. fluid-based goniometer/inclinometer 3. digital LCD goniometer 4. electronic goniometer/torsiometer. The results were as follows: Concurrent validity was highest (r= .94) with the universal and digital LCD tools. Interrater reliability (Pearson Product Moment Correlation) was good for each tool. Interrater reliability calculated by ICC(2,1) was highest (.96) with the tensiometer and lowest (.78) with the digital LCD goniometer. Intrarater reliability calculated by ICC was excellent (${\geq}.90$) for all instruments. These results show that concurrent validity, intrarater and interrater reliability are very good in the used of all four types of goniometers/inclinometer/tensiometer, even with inexperienced raters. These results confirm the almost universal reliance on hand held goniometers for joint measurement by physical therapists as being a reliable practice. Further research should be done clinically with actual patients.

  • The spread of internet media is accelerating companies to create their own on-line brand community as one of their marketing communication tools because of the advantages in terms of cost-saving and raising their brand loyalty. The purpose of this study was to examine how the consumer's activities in the customer self-driven on line fashion brand community ultimately affect building a structural relationship between brand attitude and brand loyalty. In order to conduct this study, on-line field survey was conducted including a series of filtering questions measuring respondent's level of the community participation. SPSS 18.0 and AMOS 18.0 were used for the structure equation modeling. The result of empirical analysis showed that the attachment and the loyalty of online community have significant influences on brand attitude and brand loyalty. Also, brand attitude partly played a role as a mediating variable in the path to influence brand loyalty. Lastly, the mediating effects of brand attitude may depend on participation level of these online fashion brand community relationships.

  • The objective of this study were 1) to review concepts of user information satisfaction (UIS), 2) to analyze tools for measuring user information satisfaction, 3) to identify factors affecting information satisfaction. The study was carried out by the analysis of literatures related to information system. The construct of UIS has been operationalized in many different ways. Several studies employed single-item rating scales; such scales have been criticized as unreliable. Single-item scales also provide little information as to what the user finds dissatisfying(satisfying) and are thus of limited utility outside a research setting. Multiple-item UIS measures have become increasingly common. Generally, they are of two types. The first focuses on the information system product. With such diverse names as "system acceptance", "output quality", and "appreciation", these scales focus on the content of the information system and the manner in which the information is presented. The second type of multiple-item scale includes the organizational support for developing and maintaining the system as well as the system product itself. This type of instrument contains items concerned with training, documentation, development procedures, systems maintenance, etc., as well as items related to system content. Thus it provides an indicator of the overall quality of information services provided by an information service function. Generally, UIS measures have not been carefully validated. Recently, however, several rigorous attempts have been made to develop valid and reliable UIS measure.

  • Purpose: This follow up study was performed to survey the problem in performing ADLs at home after surgery. Method: Twenty elderly patients were assessed 3 times; from the time of hospitalization for surgery until 3 weeks after discharge. Measuring tools are numeric rating scales (NRS) for pain and 3 questionnaires developed by the authors to measure difficulties in ambulation, performing indoor ADLs, and emotional status. Pearson correlation, variance analysis and descriptive statistics were used to analyze the data. Result: The level of pain significantly decreased after surgery, but the difference between pain at the time of discharge and that of 3 weeks after discharge were not significant. Pain showed a positive relationship with emotional difficulties. Elderly with a higher education, family caregiver, and regular exercise showed a lower level of emotional difficulties. Conclusion: Comprehensive approaches for chronic pain including physical, psychological, and social aspects should be considered when caring for the elderly with spinal surgery. In addition, home care nursing interventions should include an exercise program to promote adaptation and rehabilitation after discharge.

  • High-throughput transcriptome sequencing, also known as RNA sequencing (RNA-Seq), is a standard technology for measuring gene expression with unprecedented accuracy. Numerous bioconductor packages have been developed for the statistical analysis of RNA-Seq data. However, these tools focus on specific aspects of the data analysis pipeline, and are difficult to appropriately integrate with one another due to their disparate data structures and processing methods. They also lack visualization methods to confirm the integrity of the data and the process. In this paper, we propose an R-based RNA-Seq analysis pipeline called TRAPR, an integrated tool that facilitates the statistical analysis and visualization of RNA-Seq expression data. TRAPR provides various functions for data management, the filtering of low-quality data, normalization, transformation, statistical analysis, data visualization, and result visualization that allow researchers to build customized analysis pipelines.

  • Purpose: The purpose of this study is to examine the impact of type D personality on health status and health promoting behaviors in middle-aged women. Methods: A cross-sectional study design was used with 220 middle aged women. All participants completed 3 measuring tools: a 14-item Type D Personality Scale, a 12-item Short Form Health Survey Questionnaire version 2, and Health Promoting Lifestyle Profile-version II. All were completed in November 2010. Results: The prevalence of type D personality was 34.5%. Type D women had significantly lower physical (p=.020) and mental health status (p<.001) compared with non-type D women. In addition Type D women reported significantly poorer performance of health responsibility (p=.015), physical activity (p=.001), nutrition (p=.027), spiritual growth (p<.001), interpersonal relations (p<.001) and stress management (p<.001) techniques in health behaviors than non-type D women. Conclusion: Type D personality is a vulnerability factor that affects health status and is associated with poor health promoting behaviors in middle aged women. Therefore, screening for Type D personality is important to detect women at risk for health status and quality of life in community settings in Korea.
