Objectives: This study aimed to evaluate the primary care quality of a public health center in a rural area using the Korean Primary Care Assessment Tool (KPCAT). It also examined some methodological issues in applying the KPCAT and interpreting its results. Methods: Seventy-nine patients who had visited their doctor more than four times responded to the KPCAT questionnaire. Descriptive statistics and a radar chart were used in analyzing data. Sign test was used to test the KPCAT score difference by don't know option scoring methods. Results: Median and interquartile range of the public health center's KPCAT scores were forty-five and sixteen points, respectively. Only the median of the first contact domain reached the expected value of seventy-five points. The proportions of those who scored under the expected value were under fifty percent in two of four comprehensiveness items, all of three coordinating function items, two of five personalized items and all of four family/community orientation items. There were some methodological issues including, how to score don't know option and make sure response scale consistency. Conclusions: There was much room to improve the primary care quality of the rural public health center. Especially, improvement is needed in the domain of coordinating function and family/community orientation. We also hope that methodological improvement of the KPCAT contributes to more valid and reliable primary care assessment.

Single-channel recordings of TASK-1 and TASK-3, members of two-pore domain $K^+$ channel family, have not yet been reported in dorsal root ganglion (DRG) neurons, even though their mRNA and activity in whole-cell currents have been detected in these neurons. Here, we report single-channel kinetics of the TASK-3-like $K^+$ channel in DRG neurons and up-regulation of TASK-3 mRNA expression in tissues isolated from animals with spinal cord injury (SCI). In DRG neurons, the single-channel conductance of TASK-3-like $K^+$ channel was $33.0{\pm}0.1$ pS at - 60 mV, and TASK-3 activity fell by $65{\pm}5%$ when the extracellular pH was changed from 7.3 to 6.3, indicating that the DRG $K^+$ channel is similar to cloned TASK-3 channel. TASK-3 mRNA and protein levels in brain, spinal cord, and DRG were significantly higher in injured animals than in sham-operated ones. These results indicate that TASK-3 channels are expressed and functional in DRG neurons and the expression level is up-regulated following SCI, and suggest that TASK-3 channel could act as a potential background $K^+$ channel under SCI-induced acidic condition.

The purpose of this descriptive study was to evaluate the clinical validity of QSCCII (Questionnaire for the Sasang Constitution Classification), whose high accuracy as a constitutional diagnostic tool has been recognized by medical professionals. The subjects of this study were 568 clients from an A university hospital in Suwon. Of the subjects, 259 were health center visitors and 292 were ambulatory clinic visitors. Data were collected using self-reported questionnaire and were analyzed by $X^2$-test and one-way ANOVA. The results of this study as follows: 1. In 4 types of constitution, Soeumin type was found in 41.5% of the subjects. Taeumin type in 39.2%.,and Soyangin type in 19.2%, respectively. There was no Tayangin type found in this study. There were no significant differences on types of constitution by demographic characteristics such as age, sex, marital status, education, religion, and economic status. 2. As for 15 item-selective questionnaire, there were statistically significant differences on the response rate of the 12 items, except items such as A4, A11 and A14, by the types of constitution. When the subjects' own criteria on their constitution were compared to the given constitutional criteria on each item, 4 items such as A6, A11, A13 and A14 were advisable to be excluded from the questionnaire or to be reunited to the other criteria. In the meanwhile, 3 items such as A7, A18 and A15 were desirable to be re-categorized to the other constitutional types and reconstructed to the QSCC II questionnaire. 3. In terms of 106 true-false questionnaire, there were statistically significant differences on the response rate of 46 items by the types of constitution. The 46 items include 15 items (32.6%) of the domain of 'handling something/strength and weakness', 4 items (8.7%) of the domain of 'interpersonal relationship', 9 items (19.6%) of the domain of 'state of mind at ordinary times', 2 items (4.3%) of the domain of 'distinctive emotional characteristics' area, 11 items (23.9%) of the domain of 'specific behavioral trait' and 5 items (10.9%) of the domain of 'physical characteristics'. Therefore, the areas of 'handling something/strength and weakness' and' specific behavioral trait' mainly contributed to the classification of constitutional type. 4. When the 106 true-false items were simplified to the 46 items, statistically significant differences were found on the rate of items allocated to the 3 types of constitution. The rate of selection assigned to the 3 constitutional types of the simplified 46-item questionnaire was higher than that of the original 106-item questionnaire. Conclusions; It was concluded that the rate of selection of each lay person about his own constitutional type would be still higher even though the simplified items of QSCC II questionnaire were applied. If more replicated studies are conducted on the diverse population using the simplifying QSCC II questionnaire in the future, a more simplified standardized Sasang Constitution Questionnaire that is available to the public rather than to medical staffs in the clinical settings could be developed. Moreover, the simplified scale will help nurses deliver more efficient nursing care by providing a more rapid way of health assessment.

Purpose: This study was designed to construct and test a structural equation modeling on specific domain health status and the Selection Optimization Compensation (SOC) strategy affecting successful aging in elderly people. Methods: The model construction was based on the SOC model by Baltes and Baltes. Interviews were done with 201 elderly people aged 65 or older. Interview contents included demographics, functional health status, emotional health status, social health status, SOC strategies, and successful aging. Data were analyzed using SPSS 15.0 and AMOS 7.0. Results: Model fit indices for the modified model were GFI=.93, CFI=.94, and RMSEA=.07. Three out of 7 paths were found to have a significant effect on successful aging in this final model. Functional health status had a direct and positive effect on successful aging. Emotional health status influenced successful aging through SOC strategies. Conclusion: This study suggests that interventions for improving functional health status and for strengthening SOC strategies are critical for successful aging. Continuous development of a variety of successful aging programs using SOC strategy is suggested.

Objectives: The aim of the present study is to elucidate the relationship of community capacity to health in a metropolitan area in Korea. To do so, a multi-level model to verify the contextual effects of community capacity is presented. Methods: The study materials are the "The 4th Seoul Citizens Health Indicators Surveys" on 404 dong in Seoul. The community capacity indicators were developed in two strata: individual-level indicators with community identity domain; and community-level indicators with participation in community organizations, number of non-profit organizations, degree of organizing of community-based organizations, and volunteer activities. Results: Higher unhealthy probability occurs among those with lower community capacity at the community level, lower individual income, and lower community satisfaction at the individual level. It contributed to explaining self-rated health status and showed that there were contextual effects of the community going beyond the compositional effects of the individual. Conclusions: In the process of building community capacity, a community autonomously finds pending issues and solves related problems, and in so doing, raises the social quality and establishes the conditions for health promotion. Thus, the significance of neighborhood needs to be discovered and created in a new way through the development of community capacity.

This study introduces a software for real-time assessment of combustion stability for utility gas turbines. The software was written with LabView, and implemented the time-domain kurtosis as a parameter to proactively access the instantaneous combustion stability during operation of the industrial gas turbine. The simple time-domain assessment algorithm incorporated in the software is advantageous over conventional frequency-domain signal processing of dynamic pressure signal since it reduces the computational cost, thereby making the algorithm more appropriate for real-time monitoring of combustion stability. Benchmark data obtained from a model gas turbine combustor were used for the reproducibility test of the software. The assessment obtained from the software agreed well with previously published results, indicating that incorporation of the software could enhance the performance of systems monitoring the combustion stability for gas turbines during power generation.

We have developed a tool for annotation of electronic health record (EHR) data. Currently we are in the process of manually annotating a corpus of Norwegian general practitioners' EHRs with mainly linguistic information. The purpose of this project is to attain a linguistically annotated corpus of patient histories from general practice. This corpus will be put to future use in medical language processing and information extraction applications. The paper outlines some of our practical experiences from developing such a corpus and, in particular, the effects of semi-automated annotation. We have also done some preliminary experiments with part-of-speech tagging based on our corpus. The results indicated that relevant training data from the clinical domain gives better results for the tagging task in this domain than training the tagger on a corpus form a more general domain. We are planning to expand the corpus annotations with medical information at a later stage.

The existing fractal compression method is effective in generating an artificial shape by approximating its partial regions to a domain block by re-dividing the whole image into a domain region and dividing it into several domain blocks, but it is difficult to implement a computer. In this study, it is difficult to approximate a complex block such as a large-sized block and an affine transformation because a large amount of calculation is required in searching for a combination of similar blocks through a transformation, so a large amount of coding time is required.

Purpose: To develop and test the validity and reliability of the Korean version of outcome expectations-2 for exercise. Methods: The Korean version of outcome expectations for exercise-2 was developed through forward-backward translation techniques. Content, criterion, and construct validity using confirmatory factor analysis and an internal consistency reliability were conducted. Survey data were collected from 200 older adults living in a community. Results: The Korean version of outcome expectations for exercise-2 had factor loadings of the 13 items ranged from .20 to .76, and was validated by confirmatory factor analysis (CFI=.829, NFI=.754, RMSEA=.086). Also there was a reliable internal consistency with a Cronbach's ${\alpha}$ for the positive domain of outcome expectations for exercise scale-2 of .73. Negative domain, however, reported slightly low Cronbach's ${\alpha}$ of .63. Conclusion: The findings of this study demonstrated that the Korean version of outcome expectations for exercise-2 had satisfactory validity to measure expectations regarding exercise among older adults in Korea. Negative domain, however, should be retested to verify reliability for the further study.

This paper presents the results obtained using time-series-based methods for structural damage assessment. The methods are applied to a wind turbine blade structure subjected to fatigue loads. A 9 m CX-100 (carbon experimental 100 kW) blade is harmonically excited at its first natural frequency to introduce a failure mode. Consequently, a through-thickness fatigue crack is visually identified at 8.5 million cycles. The time domain data from the piezoelectric active-sensing techniques are measured during the fatigue loadings and used to detect incipient damage. The damage-sensitive features, such as the first four moments and a normality indicator, are extracted from the time domain data. Time series autoregressive models with exogenous inputs are also implemented. These features could efficiently detect a fatigue crack and are less sensitive to operational variations than the other methods.
