This qualitative study investigated different interaction patterns in an online discussion. The data was collected from asynchronous discussion occurred in a graduate course. The data analysis methods include inductive analysis and mapping strategy. The results of the study suggest three layers of interaction: response sequences, interaction amongst participants, and concept map of messages. The visualization of response sequences enabled the researcher to discover complex and dynamic interaction patterns amongst participants. The many-to-many communication feature of online discussion does not always enable direct one-on-one interaction between two participants. Rather, one message contributed to multiple threads in the stream of conversation. In terms of interaction amongst participants, the interaction amongst participants, as indicated in the data, the messages also bind each participant and consequently a group(s) of participants together. It appears that the contribution of one message may not only enable a response to one participant, but also connect many participants to each other. The concept map of messages proposes that response sequences and interaction amongst participants can also be viewed between concepts within messages in the discussion. On the surface, the messages posted by individuals are linked by the system in a linear fashion as they are posted. However, the interaction extends to collaborative conversation amongst participants. Ultimately, a conceptual network of interrelated ideas including multiple perspectives is built in asynchronous discussion.

Background: The multiple hop test is an active performance test that has been commonly used to assess individuals with functional ankle instability. Previous studies have suggested that insufficiency of dynamic postural stability and passive stability during dynamic activities can have an influence on performance in the multiple hop test. However, no study has investigated the effects of dynamic postural stability training and ankle bracing on multiple hop test performance in individuals with functional ankle instability. Objects: The purpose of this study was to compare the immediate effects of dynamic postural stability training versus ankle bracing in the performance of the multiple hop test for participants with functional ankle instability. Methods: Twenty-nine participants with functional ankle instability who scored below 24 in the Cumberland Ankle Instability Tool were selected. The participants were randomly divided into two groups: a dynamic postural stability training group (n1=14) and an ankle bracing control group ($n_2=15$). The multiple hop tests were performed before and after applying each intervention. Dynamic postural stability training was performed using visual-feedback-based balance-training equipment; participants in this group were asked to perform a heel raise in a standing position while watching the centering of their forefoot pressure to prevent excessive ankle inversion. Ankle bracing was applied in the control group. Results: When comparing the pre- and post-intervention period for both groups, both methods significantly improved the results of the multiple hop test (p<.05). However, no significant differences were shown between the dynamic postural stability training and ankle bracing groups (p>.05). Conclusion: Both dynamic postural stability training and ankle bracing showed significant improvement (2.85 seconds and 2.05 seconds, respectively) in test performance. Further study is needed to determine the long-term effects of dynamic postural stability training and to determine whether insufficient dynamic postural stability is a causative factor for functional ankle instability.

Up to the present, the evaluation measures in the production and inventory management have been studied under the pre-condition that the costs for major factors(e.g,. cost of carrying inventory, cost of demand shortage) are given easily, although in practice, it is difficult. The case in which multiple participants have a different viewpoints in production and inventory management has not been studied, in spite of its frequent occurrence. This study suggests a production and inventory model with multiple objectives corresponding to major factors and the related interactive algorithm based on the preference structures of participants. The problem can be solved through a weighting vector generated by an interaction with participants. The concept of equity is also used in order to guarantee the reasonable distribution of group utility in determining the individual relative weights of participants. This study includes the reality of the model and the decision process in the production and inventory management.

Background: The aim of this study is to assess the feasibility of acupuncture treatment for the management of subacute and chronic post-thoracotomy pain in patients with traumatic multiple rib fractures. Methods: A total of 30 participants who have undergone thoracotomy after traumatic multiple rib fractures will be recruited. Participants will be invited and equally randomised into acupuncture plus usual care and usual care alone groups. A computer-generated random number sequence will be used and concealed using opaque, sealed, sequentially numbered envelopes. Twelve sessions of manual and electrical acupuncture performed by Korean medicine doctors will be provided over a span of 3 months to participants allocated to the acupuncture group. Participants in the usual care group will continue pain medication, exercise and physical therapy as required. Study feasibility will be measured based on the proportion of patients who complete the measurement of pain at 12 or 24 weeks after baseline. The clinical outcomes will include; the average pain intensity over the recent week at rest, movement and cough, quality of life, patient's global assessment of recovery, respiratory function measured by the pulmonary function test and use of pain medication at 4, 8, 12 and 24 weeks after enrolment. Adverse events will be recorded for all participants. Written informed consent will be obtained from all participants. The local ethics committee has approved the study. This pilot trial will inform further studies investigating the potential role of acupuncture for subacute and chronic post-thoracotomy pain in patients with traumatic multiple rib fractures.

This study aimed to find the association between geographic proximity and program participation at a Healthy Family Support Center (HFSC). Drawing demographic and geographic information from the participant list at a local HFSC in Seoul for the period 2009 to 2011, this study calculated the geographic distance from the individual residence to the center for 2,343 participants. We found that single time participants had a longer distance from their residence to the center than multiple time participants. When we compared the proximity by program areas, we found that the geographic distance to the center was shorter among education program participants than among non participants. However, there was no difference in the other areas of programs. In terms of the target group, the distance was shorter among adult program participants. Finally, the average distance among participants in multiple session programs was shorter. The results of this study indicated that the relationship between geographic proximity and program participation depended on program areas, target groups, and the number of sessions.

Purpose: The purpose of this study is to analyze the effect of college sport club participants' ego-resilience on the college adjustment. Research design, data, and methodology: To accomplish the purpose, 360 participants were sampled by means stratified cluster random sampling method. Only 317 questionnaires were statistically processed, while 43 questionnaires were excluded because their respondents failed to complete instrument and judged insincere in filling out questionnaire. To analyze the data collected, statistical techniques, such as descriptive statistics, reliability analysis, independent-sample t-test, and one-way ANOVA, multiple regression analysis were used, and as for difference verification between individual groups in relation to significant results, Duncan's multiple range was conducted. Results: The following results have been drawn out via hypothesis test. First. the background variable of the college sport club participants of was proved to affect the degree of their ego-resilience on the college adjustment. Specifically, their period of participation, frequency of participation and expenses made a statistically meaningful. Second, the college sport club participants of ego-resilience were proved to affect the college adjustment. Academic adjustment, social adjustment, personal-emotional adjustment and institutional attachment made a statistically meaning-full difference. Conclusions: The findings indicate the function of sport club participants' ego-resilience in assisting their adjustment.

Physical activity (PA) professionals and participants recognize enhanced quality of life (QoL) as a benefit of and motivator for PA. However, QoL measures are often problematic and rarely consider the participants' perspective. This paper focuses on recent findings from a larger project on the role of QoL in PA and health promotion. More specifically, we focus on the views of participants and potential participants to better understand the relationship of PA and QoL. In earlier stages of the project we began with a conceptual model of QoL and developed a survey. We now focus on participants' views and ask two questions: 1) what is QoL? and 2) how does PA relate to QoL? We first asked those questions of a large sample of university students and community participants as open-ended survey items, and then asked focus groups of community participants. Overall, participants' responses reflected the multidimensional, integrative QoL model, but the responses and patterns provided information that may not be picked up with typical survey measures. Findings suggest that PA contributes to multiple aspects of QoL, that social and emotional benefits are primary motivators and outcomes for participants, and that the meaning of QoL and PA benefits is subjective and contextualized, varying across individuals and settings. Programs that directly target and highlight the multiple dimensions and integrative QoL, while considering the individual participants and contexts, may enhance both PA motivation and participants' health and QoL.

Background: Poor sleep quality is associated with psychoactive substance abuse/addiction/withdrawal. Auricular acupuncture (AA) is a nonpharmacological method used for the treatment of sleep disturbances. This study aimed to examine the quality of sleep before and after AA in participants with mental and behavioral disorders due to prior multiple drug use in the therapeutic community. Methods: This was a consecutive case series of 27 participants (25 male [92.6%]). The median age was 35.0 years (interquartile range [IQR], 29.0-37.2 years), methadone/buprenorphine were not used, and the participants were treated with AA (median number of treatments, 15.0 [IQR, 12.0-18.0]) during a median period of 51.0 days (IQR, 49.0-51.0 days) according to the National Acupuncture Detoxification Association (NADA)-Acudetox protocol. Sleep quality was determined using the Pittsburgh Sleep Quality Index (PSQI), a self-rated questionnaire that assesses sleep quality and disturbances over a 1-month interval. Results: The global PSQI score dropped (indicating better sleep quality) by a median of 3.0 points (IQR, 0.0-8.0 points) after treatment. In the multivariate logistic regression analysis, with an increase in global PSQI score during AA by 1 point, there was a 0.73-fold reduction in the risk of poor sleep quality post-AA (adjusted odds ratio, 0.73; 95% confidence interval, 0.52-1.01; p<0.055; Nagelkerke's R² =0.66). Conclusion: The results revealed a positive effect of AA (by the NADA-Acudetox protocol) on sleep quality (as measured by PSQI) among participants in a treatment center with mental and behavioral disorders due to multiple drug use.

The purpose of this study was to identify the relationships between Healthy Family Support Center (HFSC) program participation and family strengths and program needs based on HFSC participants' individual, family, and community characteristics. A total of 695 HFSC participants who were married and had participated in HFSC programs were recruited through 25 local HFSCs in Seoul. A multiple regression method was conducted for data analysis. The major findings are as follows. Family strengths was related to the variables of age, education, monthly household income, and participation in family counseling and sharing family care programs. In terms of program needs, the variables of marital conflict, difficulty in care, financial distress, family strengths, and family-friendly community were associated with HFSC program needs while participants' socio-demographic characteristics were not related to program needs. This study highlights that HFSC programs have different target populations considering that the level of family strengths was different among the various programs' participants. In addition, program needs are different depending upon the HFSC participants' experiences in the family and community. These findings suggest that it is important to consider participants' family and community characteristics as well as participants' socio-demographic characteristics to provide appropriate programs for all HFSC participants.
