Purpose: There has been a need to integrating the self-help program for arthritis with the TaiChi for arthritis patient. The purpose of this study was to develop and to examine the effect of the Self-help and Tai Chi for arthritis (SHTCA) program for arthritis. Method: This study was designed non equivalent control group pre-post test, quasi-experimental design. A total 40 participants were recruited in W-city, 29 participants(14-experimental group and 15-control group) completed post test. The experimental group participated in the SHTCA once a week for 8 weeks. SHTCA program was consisted of understanding of the arthritis, contracting of the promise, exercise for muscle strength and joint flexibility and 8 movements of Tai Chi exercise. Coloring plus program to cellular phone was used to encourage the exercise and participation by the KT-SHUT twice a week. Measures used to examine the effect of the SHTCA were EQ-5D standardized five dimensions(mobility, self-care, usual activities, pain & discomfort, and anxiety & depression), and health perception, joint flexibility, grasping power, and balance. Collected data was analyzed by SPSS WIN 14.0. Results: The experimental group had significantly increased the EQ-mobility(p=.033), health perception(p=.000), right shoulder flexibility(p=.007), and left shoulder flexibility(p=.002) compared to the control group. In addition, pain was decreased(p=.052) and right grip was increased(p=.052) after 8 weeks program in the experimental group.

Purpose: Head movement during brain perfusion SPECT (Diamox) scan is a one of important issues which decreases image quality. It also causes repeated scans. This study was designed to evaluate variable factors causing scan failures. Materials and Methods: 676 patients (359 men, 317 women, age average $54.5{\pm}18.4$) for brain perfusion SPECT (Diamox) scan from March, 2010 to Feb. 2011 were used as a subject. Age data and the kind of disease(Moyamoya disease (MMD), None moyamoya disease (NMMD), Cerebral infarction (CI)), test performance outcome (success,failure) were collected. The head movement factors(gender, disease, age, head fixation device) were evaluated by chi-square test and logistic regression analysis Results: The result showed that men had higher scan failure rate than women. Seniors in seventies(men 3.4%, women 1.5%) showed the most highest failure rate. Using head fixation device increased scan success rate up to 94.4~97.7%. The scan success rate is dependent upon gender, head fixation device by chi-square test(${\chi}^2$=3.8 (df=1, p<0.05), ${\chi}^2$=10.4 (df=1, p<0.001)) Gender, disease(CI), head fixation device showed very effective result in logistic regression analysis.(Wald=3.3 (p<0.07), Wald=3.7 (p<0.05), Wald=9.3 (p<0.05) Conclusion: It is demonstrated that gender, disease, using head fixation device is statistically very useful factors. Especially, head fixation device is a main key minimizing repeated scan.

The main objective of this paper is to test the major prediction of the Aspect Hypothesis on interlanguage narratives collected from 171 Ibibio ESL learners in a classroom setting using sets of picture stories. Aspect Hypothesis predicts that lexical aspectual classes of verbs would determine the pattern of acquisition and distribution of tense-aspect morphology at the very early stages of L2 acquisition of tense-aspect verbal morphology. That is, telic verbs would be marked with the past tense-aspect verbal morphology before atelic verbs in the interlanguage of ESL learners irrespective of their L1 background. The results of our data analyses show a significant effect from the lexical aspect on the acquisition and distribution of tense-aspect morphology with chi-square statistics of ($x^2=196.92$,df = 6, n = 1664, p = <.0001). However, the effect of the lexical aspect is shown to be more prominent among Ibibio ESL learners at higher levels of proficiency. This is contrary to the prediction regarding Aspect Hypothesis. The paper concludes that the influence of the lexical aspect on the pattern of acquisition and distribution of tense-aspect morphology may be universal but the actual point along the developmental pathway when such influence is obtainable is yet to be determined. This calls for more research into the pattern of the L2 acquisition of tense-aspect verbal morphology.

When the number of parameters in the time series model are diverse, it is hard to forecast because of the increasing error by a parameter estimation. If the homogeneity hypothesis which was obtained from the same model about severeal data for the time series is selected, it is easy to get the predictive value better. Nonlinear time-series panel data for each parameter for each time series, since there are so many parameters that are present, and the large number of parameters according to the parameter estimation error increases the accuracy of the forecast deteriorated. Panel present in the time series of multiple independent homogeneity is satisfied by a comprehensive time series to estimate and to test of the parameters. For studying about the homogeneity test for the m independent non-linear of the time series panel data, it needs to set the model and to make the normal conditions for the model, and to derive the homogeneity test statistic. Finally, it shows to obtain the limit distribution according to ${\chi}^2$ distribution. In actual analysis,, we can examine the result for the homogeneity test about nonlinear time series panel data which are 2 groups of stock price data.

Purpose: This study examined the effects of a hospice palliative education program for adults on their perception of hospice, attitude towards death, and meaning of life. Methods: This study was a quasi-experimental study with a non-equivalent control group design. Among 43 participants, 22 were assigned to the non-equivalent experimental group and 21 to the control group. The hospice palliative education program comprised 10 three-hour sessions, each given once a week. Data were analyzed by descriptive statistics, t-test and ${\chi}^2-test$ using SPSS version 20.0. Results: Significant differences between the experimental and control groups were observed in their perception of hospice (t=6.63, P<0.001), attitude towards death (t=2.36, P=0.023), and meaning of life (t=5.06, P<0.001). Conclusion: The results indicate that this education program could positively affect the perception of hospice, attitude toward death, and meaning of life in adults. More studies are warranted to explore the effects of this education program for various age groups so that it may help more people get positive understanding of hospice palliative care. The results suggest this program could help improve the negative perception of hospice, negative attitude towards death and meaning of life that are generally held by the public.

The aim of this study was to evaluate the microleakage of teeth according to root canal preparation with & without apical enlargement in various size of apical foramen. 60 extracted one canal roots were cross-cutted at 5 mm from root apex and divided into two groups according to their apical foramen size of large (L) and small (S). Each group was subdivided into two groups accordance with their cross-sectional configuration at 5 mm from apex, round (R) and ovoid (O); SR Group, SO Group LR Group, LO Group. Each group was shaped in .02 taper by Quantec series Nickel-Titanium (NiTi) rotary file, obturated by lateral condensation method. Leakage was measured using a fluid transport model under 40 $cmH_2O$ pressure. After the leakage test, blocks which had showed the leakage retreated with .04 taper and ,06 taper and evaluated the degree of fluid filtration in each group. The data was analysed statistically using chi-square test and fisher's exact test. The results obtained were as follows : 1. Significant difference in leakage was found in groups which had different apical foramen size in .02 taper instrumentation (p < 0.05), but not in .04 taper instrumentation (p > 0.05) 2. The difference in microleakage according to the shape of canal was not evident at 5 mm from apex (p > 0.05). 3. There was correlation between .02 taper instrumentation and .04 taper instrumentation in LR group, LO group (p < 0.05).
