Purpose: The purpose of this study was to investigate the level of self management behavior of patients with type 2 diabetes and to compare the factors influencing self management behavior between the elderly and adults. Methods: The participants consisted of 105 adults and 100 elderly who visited the outpatient department of a hospital from August to December 2011. Data was collected by questionnaires and analyzed using the SPSS/WIN 18.0. Results: The elderly showed higher mean scores of subcategory of self management behavior than adults. In stepwise multiple regression analysis, a total of 42% (adults), 52% (elderly) respectively of variance in self management behavior were accounted for by self-efficacy, perceived barriers, perceived benefits, yes or no smoking and regular exercise in adults and readiness, self efficacy, perceived benefits in the elderly. Conclusion: Therefore, a diabetics intervention program should be designed and provided as a tailored one for adults and elderly separately in Korea. In the strategy for adults with type 2 diabetes in the promotion of self efficacy, perceived benefits and reduction of perceived barriers, and correction of life habits such as smoking and exercise are needed, whereas in the elderly promotion of readiness, self efficacy, perceived benefits are required.

The structure of the actual detector was computed using the code of the PENELOPE. Using the standard mixed sources (450, 1,000 ml), compare the effectiveness of each energy according to various densities and height of the PENELOPE computer simulation, and calculate the effectiveness of the various environmental specimens and apply them to various environmental specimens to determine the lower limit. The values obtained by the obtained value were obtained by applying the obtained efficiency to the actual environmental specimens and obtaining the lower limit values. The density correction factor is 1.155 g of the density correction factor of $0.4g/cm^3$ (59.54keV), 1.153 (661 keV), $1.06g/cm^3$ 1.064 (1,836.04keV), 1.03, and 1.033. It was confirmed that the radioactivity concentration of environmental samples decreased as the amount of specimen was measured increases, and the MDA value decreased as time measured increases.

The purpose of this study was to investigate the quantitative data of downward pulling tension in subjects with scapular downward rotation syndrome (SDRS) before and after 6-week self scapular upward rotation exercise (SURE) program. Eleven subjects with bilateral SDRS. The downward pulling tension(DPT) was measured digital tension-meter. The tension force data were collected using a surface electromyography before and after a 6-week self-scapular SURE program. The significance of difference between pre- and post-program was assessed using a paired t-test, with the level of significance set at ${\alpha}$=.05. The results showed that significant differences between pre- and post-SURE program were found for DPT (p<.05). These findings suggest that 6-week self SURE program is effective for reducing DPT in subjects with SDRS. Additionally, our DPT measurement can be useful for maintaining shoulder position and providing quantitative data between pre- and post-SURE program during passive correction of scapular position test.

In this paper, a new method for finding optimal and short span in Convolutional Self-Doubly Orthogonal(CDO) codes are proposed. This new algorithm based on Parallel Implicitly-Exhaustive search, where we applied dynamic search space reduction methods in order to reduce computational time for finding Optimal Span for R=1/2 rate CDO codes. The simulation results shows that speedup and error correction performance of the new algorithm is better.

Purpose: This study aimed to compare the oxygen saturation measured at fingertips with unpolished and self-artificial nails (sticker, tip) using a portable pulse oximeter. Methods: The sample comprised 27 women who had used nail care services. Using a pulse oximeter, oxygen saturation was measured at fingertips with unpolished nails in a stable state. Self-fabricated sticker and tip nails were attached to the right and left hands, respectively, using five nail colors (black, blue, green, purple, and brown). Oxygen saturation was measured at fingertips with self-fabricated nails first in the usual manner and then measured again by rotating the oximeter by 90°. Values of oxygen saturation were compared and analyzed using the Friedman test and Wilcoxon signed-rank test with Bonferroni correction using IBM SPSS 26.0. Results: Oxygen saturation values were significantly different among colors for both sticker nails (p=.036) and tip nails (p=.000), with black self-artificial nails tending to demonstrate lower oxygen saturation. Moreover, oxygen saturation values obtained by measuring the usual way on unpolished nails was significantly different than those obtained by rotating the oximeter by 90° on thumb with sticker (p=.001) and tip nails (p=.001). Conclusion: The findings of this study suggest that oxygen saturation should be measured on other fingers except for thumb instead of removing the self-artificial nails in emergency situations. For patients with black self-artificial nails, is the findings recommend measuring oxygen saturation at other body parts such as toes, earlobes, forehead, etc.

A new method of calculating sensitivity coefficients of core characteristics relative to infinite-dilution cross sections has been developed. Conventional sensitivity coefficients are evaluated for the changes of effective cross sections which are dependent on individual models of core and cell. Therefore a correction has been derived to the conventional sensitivity coefficients based on the perturbation theory. The accuracy of the present method has been verified by comparing numerical results of sensitivity coefficients with a reference Monte-Carlo method.

The purposes of the study are to introduce and apply an activity that can help improve student-initiated learning on the TOEIC Speaking Test (TOEICST) performance and to see students' attitude toward the activity. Twenty-eight university students in Chungcheong province engaged in learning based on this activity. In the present study, the activity proposed by McCormick and Vercellotti (2013) and Stillwell, Curabba, Alexander, Kidd, Kim, Stone, & Wyle (2010) was modified and adapted[14][19]. The outline of the Task Recording Activity (TRA) consisted of three steps: preparation step, Task Recording Activity step, and evaluation step. As data collection of the study, a survey and students' journal were utilized and qualitatively analyzed. The results showed that student-initiated learning activity could be applied positively not only in communicative lessons, but in TOEICST specific lessons as well. Additionally, participants showed positive attitudes toward self-transcription and self-correction. Some implications of the study are that the TRA can be applied to generate autonomous learners studying for the TOEIC Speaking Test, that the guideline for different proficiency can be developed to help them improve their self-reflection, and that students need to have an active attitude to lead their own learning.

PURPOSE: The purpose of this study was to provide clinical basic data to reduce pain and improve function by comparing neck muscle activity and neck alignment using self-stretching and passive stretching exercises for chronic neck pain caused by forward head posture. METHODS: The subjects were divided into 15 subjects assigned to perform self-stretching exercise and 15 subjects assigned to perform passive stretching exercise. The intervention was conducted for a total of 4 weeks. The muscle activity in the neck was measured by surface electromyography (EMG) before intervention, and craniovertebral and cranial rotation angles were measured by X-ray. The 4-week intervention was conducted and the above items re-measured in the same manner and analyzed. RESULTS: Muscle activity within both groups after intervention using self-stretching or passive stretching exercise was significantly different (p < .05)(p < .01). Neck alignment of both groups was significantly different (p < .001)(p < .01). Further, muscle activities of the upper trapezius and splenius capitis muscles showed significant differences (p<.05). Lastly, neck alignment showed statistically significant difference (p < .05). CONCLUSION: Self-stretching exercise activated motor nerves as a posture correction exercise, thereby improving inhibition of muscle activity, muscle contraction delay, and pathological conditions of the muscle. For future research, interventions of self-stretching exercise will be needed for patients with chronic back pain accompanied by forward head posture, and various clinical studies on postural improvement of forward head posture by maintaining a normal muscle tone state are needed.
